CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Disclosure controls and procedures are defined in Rule 13a-15(e) under the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), to mean controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the United States Securities and Exchange Commission’s (the “Commission”) rules and forms.

At the direction of the Registrant’s Chief Executive Officer and Chief Financial Officer, management evaluated disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, management concluded that the Registrant’s disclosure controls and procedures were effective as at December 31, 2019.

See the disclosure provided under the heading “Disclosure Controls and Procedures and Internal Control over Financial Reporting” on pages 33 - 34 of Exhibit 99.3, the Registrant’s Management’s Discussion and Analysis (the “MD&A”) which is incorporated by reference herein.

Management’s Annual Report on Internal Control over Financial Reporting and Attestation Report of the Registered Public Accounting Firm

Management is responsible for establishing and maintaining adequate disclosure controls and procedures and internal control over financial reporting as described in the annual MD&A. Management evaluated the effectiveness of the design and operation of internal control over financial reporting based on the framework and criteria established in the Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that evaluation, management concluded that the Registrant's internal control over financial reporting was effective as of December 31, 2019.

Internal control, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives and due to its inherent limitations, may not prevent or detect all misrepresentations. Furthermore, the effectiveness of internal control is affected by change and subject to the risk that internal control effectiveness may change over time.

This annual report does not include an attestation report of the Registrant’s registered public accounting firm regarding internal control over financial reporting.

The report of management on our internal control over financial reporting is provided under the heading “Management’s Report” in the Registrant’s audited consolidated financial statements, which is filed as Exhibit 99.2 and is incorporated by reference herein.

Changes in Internal Control Over Financial Reporting

There were no significant changes in the design of the Registrant’s internal control over financial reporting during the year ended December 31, 2019 that have materially affected, or are reasonably likely to materially affect, the operation of the Registrant’s internal control over financial reporting.

IDENTIFICATION OF THE AUDIT COMMITTEE

The Registrant has a separately-designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Exchange Act (the “Audit Committee”). The Audit Committee comprises Russel Robertson (Chair), Anne Giardini, David Hay, Jessica McDonald and William Sheffield. The board of directors of the Registrant has determined that each member of the Audit Committee is “independent” as defined in the Exchange Act and the New York Stock Exchange’s listing standards applicable to the Registrant. Each of the Audit Committee members has an

understanding of the accounting principles used to prepare the Registrant’s financial statements and varied experience as to the general application of such accounting principles, as well as an understanding of the internal controls and procedures necessary for financial reporting.

AUDIT COMMITTEE FINANCIAL EXPERT

The board of directors of the Registrant has determined that it has two audit committee financial experts serving on its audit committee. Russel Robertson and David Hay have each been designated as an audit committee financial expert and are each independent, as such term is defined in the New York Stock Exchange’s listing standards applicable to the Registrant. The Commission has indicated that the designation or identification of an audit committee financial expert does not deem an “expert” for any purpose, impose any duties, obligations or liability on such expert that are greater than those imposed on members of the audit committee and board of directors who do not carry this designation or identification, or affect the duties, obligations or liability of any other member of the audit committee or board of directors.

AUDIT COMMITTEE PRE-APPROVAL POLICIES AND PROCEDURES

The charter of the Audit Committee requires that the Audit Committee review and approve all policies and procedures for the pre-approval of services to be rendered by external auditors. All permissible non-audit services to be provided to the Registrant or any of its affiliates by external auditors or any of their affiliates that are not covered by pre-approval policies and procedures approved by the Audit Committee, are subject to pre-approval by the Audit Committee. During the fiscal year ended December 31, 2019, the waiver of pre-approval provisions set forth in the applicable rules of the Commission were not utilized for any services related to Audit-Related Fees, Tax Fees or All Other Fees and the Audit Committee did not approve any such fees subject to the waiver of pre-approval provisions.

Therefore, actual outcomes and results may differ materially from what is expressed, implied or forecasted in such

forward-looking information. Hydro One does not intend, and it disclaims any obligation to update any forward-looking information, except as required by law.

The forward-looking information in this annual information form is based on a variety of factors and assumptions including, but not limited to: no unforeseen changes in the legislative and operating framework for Ontario’s electricity market; favourable decisions from the OEB and other regulatory bodies concerning outstanding and future rate and other applications; no unexpected delays in obtaining required regulatory approvals; no unforeseen changes in rate orders or rate setting methodologies for Hydro One’s distribution and transmission businesses; no unfavourable changes in environmental regulation; continued use of U.S. GAAP; a stable regulatory environment; no significant changes to the Company’s current credit ratings; no unforeseen impacts of new accounting pronouncements; and no significant event occurring outside the ordinary course of business. These assumptions are based on information currently available to Hydro One, including information obtained from third-party sources. Actual results may differ materially from those predicted by such forward-looking information. While Hydro One does not know what impact any of these differences may have, Hydro One’s business, results of operations, financial condition and credit stability may be materially adversely affected if any such differences occur. Factors that could cause actual results or outcomes to differ materially from the results expressed or implied by forward-looking information include, among other things:

•	regulatory risks and risks relating to Hydro One’s revenues, including risks relating to rate orders and the rate-setting models for transmission and distribution, actual performance against forecasts and capital expenditures, the regulatory treatment of the deferred tax asset, the recoverability of total compensation costs or denials of applications;
•	risks associated with the Province’s share ownership of Hydro One and other relationships with the Province, including potential conflicts of interest that may arise between Hydro One, the Province and related parties, risks associated with the Province’s exercise of further legislative and regulatory powers in the implementation of the Hydro One Accountability Act and the Fixing the Hydro Mess Act, risks relating to the ability of the Company to attract and retain qualified executive talent or the risk of a credit rating downgrade for Hydro One Inc. and its impact on the Company’s funding and liquidity;
---	---
•	risks relating to the location of the Company’s assets on Reserve lands and the risk that Hydro One may incur significant costs associated with transferring assets located on Reserves;
---	---

ELECTRICITY INDUSTRY OVERVIEW

General Overview

The electricity industry is made up of businesses that generate, transmit, distribute and sell electricity. While traditionally a mature and stable industry, the electricity industry is facing technological change and increasing innovation. Hydro One’s business is focused on the transmission and distribution of electricity.

•	Transmission refers to the delivery of electricity over high voltage lines, typically over long distances, from generating stations to local areas and large industrial customers.
•	Distribution refers to the delivery of electricity over low voltage lines to end users such as homes, businesses and institutions.
---	---

Overview of an Electricity System

The basic configuration of a typical electricity system showing electricity generation, transmission and distribution is illustrated in the following diagram:

Note:

The above image shows a typical electricity system with transmission-connected generation.

Transmission and distribution networks are sometimes referred to as the “electricity grid” or simply “the grid”.

THE ELECTRICITY INDUSTRY IN ONTARIO

Regulation of Transmission and Distribution

General

The Electricity Act and the Ontario Energy Board Act establish the general legislative framework for Ontario’s electricity market. The activities of transmitters and distributors in Ontario are overseen by three main regulatory authorities: (i) the OEB, (ii) the IESO, and (iii) the Canadian Energy Regulator. The Minister of Energy is responsible for developing long-term energy plans and has the power to issue directives to the IESO and the OEB regarding implementation of such plans.

Ontario Energy Board

The OEB is an independent regulatory agency. The Ontario Energy Board Act provides the OEB with the authority to regulate Ontario’s electricity market, including the activities of transmitters and distributors.

The OEB has the following legislated objectives in relation to the electricity industry:

•	to protect the interests of consumers with respect to prices and the adequacy, reliability and quality of electricity service,
•	to promote the education of consumers,
---	---
•	to promote economic efficiency and cost effectiveness in the generation, transmission, distribution, sale and demand management of electricity and to facilitate the maintenance of a financially viable electricity industry,
---	---
•	to promote electricity conservation and demand management in a manner consistent with the policies of the Province, including having regard to the consumer’s economic circumstances,
---	---
•	to facilitate the implementation of a smart grid in Ontario, and
---	---
•	to promote the use and generation of electricity from renewable energy sources in a manner consistent with the policies of the Province, including the timely expansion or reinforcement of transmission systems and distribution systems to accommodate the connection of renewable energy generation facilities.
---	---

The OEB is responsible for, among other things, approving transmission and distribution rates in Ontario. It also approves the construction, expansion, or reinforcement of transmission lines greater than two kilometres in length, as well as mergers, acquisitions, amalgamations and divestitures involving distributors, transmitters and other entities which it licenses. The activities of transmitters and distributors are subject to

the conditions of their licences and a number of industry codes issued by the OEB. These codes and other requirements prescribe minimum standards of conduct and service for licensed participants in the electricity market.

In December 2017, the OEB posted its Strategic Blueprint: Keeping Pace with the Evolving Energy Sector (“Strategic Blueprint”), setting out the OEB’s commitment to modernize its approach to regulation over the next five years. The OEB established the Advisory Committee on Innovation (“ACI”) to identify steps to develop a modern regulatory framework in response to technological changes occurring in the energy sector. The ACI presented its report to the OEB in November 2018. The report focused on electricity distribution and identified four broad actions for the OEB to take to create an environment that supports innovation that brings value to customers: provide a transparent and level playing field; remove disincentives to innovative solutions; encourage market-based solutions and customer choice; and embrace simplified regulation. In January 2019, the OEB launched its “Innovation Sandbox” which is in line with recommendations made by the ACI that the OEB provide a way for utilities and unregulated companies to discuss regulatory issues with the OEB. The Innovation Sandbox is meant to advance the OEB’s focus on innovation and customer choice, pursuant to the Strategic Blueprint. In March 2019, the OEB initiated two consultation processes, Utility Remuneration and Responding to Distributed Energy Resources, to support the evolution of the sector in response to the recommendations by the ACI. Subsequent to an initial stakeholder session held in September 2019, the OEB indicated that it would prepare and issue for comment a scoping paper to identify the specific objectives and issues to be considered for each consultation. In January 2020, the OEB announced an additional stakeholder session to be held, following which the OEB has invited stakeholder comments until March 20, 2020.

Also in December 2017, the Province established a panel to modernize the OEB. The panel was tasked with providing advice on opportunities to strengthen the governance and operational framework of the OEB. In March 2019, the panel released the Ontario Energy Board Modernization Review Panel Final Report, which outlined its recommendations for opportunities to reform the OEB’s governance and operations. Flowing from the recommendations of the panel’s report, the Fixing the Hydro Mess Act reforms the OEB’s governance structure. See “The Electricity Industry in Ontario – Issues Affecting the Electricity Industry Generally – Recent Government Electricity Sector Changes – Fixing the Hydro Mess Act”.

IESO

The IESO delivers key services across the electricity sector, including managing the power system in real time, planning for Ontario’s future energy needs, enabling conservation and designing a more efficient electricity marketplace to support sector evolution. Transmitters and other wholesale market participants must comply with the Market Rules issued by the IESO. The Market Rules require transmitters to comply with mandatory North American reliability standards for transmission issued by the North American Electric Reliability Corporation (“NERC”) and the Northeast Power Coordinating Council, Inc. (“NPCC”). The IESO enforces these reliability standards and coordinates with system operators and reliability agencies in other jurisdictions to ensure energy adequacy and security across the interconnected bulk electricity system in North America.

In March 2019, the Province directed the IESO to assume accountability for centralized delivery of conservation programs, in contrast to a local distribution company delivery model. The Province also directed the IESO to discontinue the 2015-2020 CDM framework and to implement a new interim framework. The IESO implemented an interim framework, in effect from April 1, 2019 to December 31, 2020, which offers energy-efficiency incentives and rebates to electricity customers. See “Business of Hydro One – Distribution Business Segment – Regulation – Conservation and Demand Management” for more details.

Canadian Energy Regulator

In August 2019, the Canadian Energy Regulator Act came into force, replacing the National Energy Board Act. As a result of the new statute, the National Energy Board became the Canadian Energy Regulator. Any decision or order made by the National Energy Board is considered to have been made under the Canadian Energy Regulator Act and may be enforced as such.

The Canadian Energy Regulator has jurisdiction over the construction and operation of international power lines, as well as interprovincial lines that are designated as being under federal jurisdiction (of which there are currently none). As Hydro One owns and operates 11 active international power lines connecting Ontario’s transmission system with transmission systems in Michigan, Minnesota and New York, Hydro One holds several certificates and permits with the Canadian Energy Regulator.

Transmission

Transmission companies own and operate transmission systems that deliver electricity over high voltage lines. Hydro One’s transmission system accounts for approximately 98% of Ontario’s electricity transmission capacity based on the revenues approved by the OEB. The Company’s transmission system is interconnected to systems in Manitoba, Michigan, Minnesota, New York and Quebec and is part of the North American electricity grid’s Eastern Interconnection. The Eastern Interconnection is a contiguous electricity transmission system that extends from Manitoba to Florida and from east of the Rocky Mountains to the North American east coast. Being part of the Eastern Interconnection provides benefits to Ontario, such as greater security and stability for Ontario’s transmission system, emergency support when there are generation constraints or shortages in Ontario, and the ability to exchange electricity with other jurisdictions.

Distribution

Distributors own and operate distribution systems that deliver electricity over power lines at voltages of 50kV or less to end users. A local distribution company is responsible for distributing electricity to customers in its OEB-licensed service territory, and in some cases to other distributors. A service territory may cover large portions or all of a particular municipality, or an otherwise-defined geographic area. Distribution customers include homes, commercial and industrial businesses and institutions such as governments, schools and hospitals.

In Ontario, as per the OEB’s 2018 Yearbook of Electricity Distributors, as at December 31, 2018, 63 local distribution companies provided electricity to approximately five million customers. The distribution industry in Ontario is fragmented, with the 15 largest local distribution companies accounting for approximately 83% of the province’s customers.

Through its wholly-owned subsidiary Hydro One Inc., Hydro One owns the largest local distribution business in Ontario, which serves approximately 1.4 million predominantly rural customers, or approximately 26% of the total number of customers in Ontario.

Issues Affecting the Electricity Industry Generally

Tax Incentives

Tax incentives were included in the 2015 Ontario budget to promote consolidation in the electricity distribution sector. The 2015 Ontario budget announced a reduction in the tax rate for transfers of electricity assets from 33% to 22% and to nil for distributors with fewer than 30,000 customers. In addition, the budget introduced a capital gains exemption where capital gains arise as a result of exiting the payments in lieu of corporate taxes regime. These incentives are in place until December 31, 2022.

Ontario 2017 Long-Term Energy Plan

In October 2017, the Province released its 2017 Long-Term Energy Plan, which set out a number of initiatives for Ontario’s energy system, including: ensuring affordable and accessible energy, ensuring a flexible energy system, innovating to meet the future, improving value and performance for consumers, strengthening its commitment to energy conservation and efficiency, responding to the challenge of climate change, supporting First Nation and Métis capacity and leadership, and supporting regional solutions and infrastructure. The IESO and the OEB developed implementation plans in support of the objectives of the 2017 Long-Term Energy Plan, and each implementation plan was approved by the Minister of Energy in February 2018.

Recent Government Electricity Sector Changes

Fixing the Hydro Mess Act

In May 2019, the Fixing the Hydro Mess Act received Royal Assent. The following key changes flowed from this statute:

•	Reform of the OEB’s structure through the creation and appointment of a board of directors, led by a chair, responsible for governance and strategic oversight of the OEB; the creation of the role of CEO, separate from the chair, to provide executive leadership; and the creation of commissioners to adjudicate hearings and determine matters within the OEB’s jurisdiction;
•	Upload of conservation programs from local distribution companies to the IESO;
---	---
•	Limiting residential electricity rate increases to the rate of inflation; and
---	---

•	Insertion of on-bill rebates on customer bills.

Legislative Provisions Specific to Hydro One

In addition to legislation in Ontario that impacts all transmitters and distributors, there is legislation that is specific to Hydro One. Specifically, the Electricity Act requires Hydro One’s head office and principal grid control centre to be maintained in Ontario, restricts the disposition of substantially all of its OEB-regulated transmission or distribution business, prohibits any change to its jurisdiction of incorporation, requires the Company to have an ombudsman, contains a 10% ownership restriction with respect to Voting Securities and restricts the Province from selling Voting Securities if it would own less than 40% of the Voting Securities of any class or series as a result of the sale.

Ombudsman

The Electricity Act requires the Company to have an ombudsman to act as a liaison with customers and to establish procedures for the ombudsman to inquire into and report to the Board on matters raised with the ombudsman by or on behalf of customers. See “Business of Hydro One – Ombudsman” for more information.

10% Ownership Restriction

The Electricity Act imposes share ownership restrictions on the Voting Securities. These restrictions provide that no person or company (or combination of persons or companies acting jointly or in concert) may beneficially own or exercise control or direction over more than 10% of any class or series of Voting Securities, including common shares of the Company (the “Share Ownership Restrictions”). The Share Ownership Restrictions do not apply to Voting Securities held by the Province, nor to an underwriter who holds Voting Securities solely for the purpose of distributing those securities to purchasers who comply with the Share Ownership Restrictions. The articles of Hydro One Limited provide for comprehensive enforcement mechanisms that are applicable in the event of a contravention of the Share Ownership Restrictions.

Maintenance of 40% Ownership

As of December 31, 2019, the Province owned approximately 47.3% of Hydro One Limited’s common shares. See the Annual MD&A under the heading “Risk Management and Risk Factors” for more information.

The Electricity Act restricts the Province from selling Voting Securities (including common shares of Hydro One Limited) if it would own less than 40% of the outstanding number of Voting Securities of that class or series after the sale. If as a result of the issuance of additional Voting Securities by Hydro One Limited, the Province owns less than 40% of the outstanding number of Voting Securities of any class or series, the Province must, subject to the approval of the Lieutenant Governor in Council and the necessary appropriations from the Legislature, take steps to acquire as many Voting Securities of that class or series as are necessary to increase the Province’s ownership to not less than 40% of the outstanding number of Voting Securities of

that class or series. The manner in which, and the time by which, the Province must acquire these additional Voting Securities will be determined by the Lieutenant Governor in Council.

The Province has been granted pre-emptive rights by Hydro One Limited to assist it in meeting its ownership requirements under the Electricity Act as described under “Agreements with Principal Shareholder – Governance Agreement – Other Matters – Pre-emptive Rights”.

Hydro One Accountability Act

In August 2018, the Province passed the Hydro One Accountability Act, requiring the Board to establish a new compensation framework for the Board, CEO and certain other executives, as defined in the legislation, in consultation with the Province and the other five largest shareholders of Hydro One Limited. In accordance with this legislation, the Province was required to approve the new executive compensation framework and is required to approve any amendments to it. In February 2019, pursuant to the Hydro One Accountability Act, the Province issued a directive to Hydro One which set out certain compensation-related requirements for the CEO, other executives and the Board that Hydro One is required to follow when developing its board and executive compensation framework, and in March 2019, the Province approved a new compensation framework that Hydro One submitted in compliance with the directive. Key highlights of the new compensation framework include, among other things, a maximum total direct compensation for the CEO and other executives and a cap on annual board compensation. Also in accordance with the Hydro One Accountability Act, the Ontario Energy Board Act was amended to preclude the OEB from approving or fixing rates for Hydro One that include any amount in respect of compensation paid to the CEO and certain other executives.

The Hydro One Accountability Act also requires Hydro One to annually provide public disclosure concerning compensation paid to certain executives. Our compensation framework can be found on our website.

Elimination of Certain Legislation With Respect to Hydro One

In 2015 and 2016, Hydro One Inc. and its subsidiaries ceased to be subject to a number of Ontario statutes that apply to entities owned by the Province. Hydro One Limited is similarly not subject to those statutes. Notwithstanding the elimination of certain legislation with respect to Hydro One, the Company is required under the Financial Administration Act and the Auditor General Act to provide financial information to the Province for the Province’s public reporting purposes.

RATE-REGULATED UTILITIES

Rate Applications in Ontario

Framework

The term “rate-regulated” is used to refer to an electricity business whose rates for transmission, distribution and other services are subject to approval by a regulator. The rate base of a rate-regulated utility means the net book value of the regulated assets of the utility, plus an allowance for working capital. The OEB is the regulator that approves electricity transmission and distribution rates in Ontario. Transmission and distribution rates have historically been determined using either a cost-of-service model or a performance-based model, which typically includes a cost-of-service base year. These models are reviewed and modified by the OEB from time to time. The OEB is currently considering alternative approaches to utility remuneration and incentives.

In a cost-of-service model, a utility charges rates for its services that allow it to recover the costs of providing its services and earn an allowed return on equity. A utility’s return on equity, or “ROE”, is the rate of return that a regulator allows the utility to earn on the equity portion of the utility’s rate base. The utility’s costs of providing its services must be prudently incurred. Cost savings are typically passed on to customers in the form of lower rates reflected in future rate decisions.

Cost of Service ($)	+	Return on Equity ($)	=	Revenue Requirement ($)

In a performance-based model, a utility also charges rates for its services that allow it to recover the costs of providing its services and earn an allowed return on equity. However, rates are adjusted formulaically in years subsequent to the initial rebasing of costs. The formulaic adjustments in a performance-based model consider inflation and expectations regarding productivity. They assume that the utility becomes increasingly efficient over time. If a utility achieves cost savings in excess of those established by the regulator, the utility may retain some or all of the benefits of those cost savings, which may permit the utility to earn more than its allowed return on equity. In Ontario, transmission and distribution rates, including those of Hydro One, are now generally determined using a performance-based model.

GENERAL DEVELOPMENT OF THE BUSINESS

Chronological Development of the Business

Background

In August 2015, Hydro One Limited was incorporated by the Province as its sole shareholder. In November 2015, Hydro One Limited completed its initial public offering on the TSX by way of a secondary offering of 81,100,000 common shares by the Province. Hydro One Limited did not receive any proceeds from the initial public offering. Prior to the closing of the initial public offering, all of the issued and outstanding common shares of Hydro One Inc. were acquired by Hydro One Limited. In April 2016, the Province completed a further secondary offering of approximately 83,300,000 common shares of Hydro One Limited.

The following key events occurred from 2017 to 2019 in respect of Hydro One, beginning in 2017.

2017

2017 Secondary Common Share Offering

In May 2017, the Province completed a secondary offering of 120,000,000 common shares of Hydro One Limited at a price of $23.25 per share for aggregate gross proceeds to the Province of approximately $2.79 billion. Following completion of this offering, the Province held approximately 49.9% of Hydro One’s total issued and outstanding common shares. Hydro One did not receive any of the proceeds from the sale of the common shares by the Province.

Exemptive Relief – Disclosure of Ownership by the Province

In June 2017, the Canadian securities regulatory authorities granted (i) the Minister of Energy, (ii) Ontario Power Generation Inc. (on behalf of itself and the segregated funds established as required by the Nuclear Fuel Waste Act) and (iii) agencies of the Crown, provincial Crown corporations and other provincial entities (collectively, the “Non-Aggregated Holders”) exemptive relief, subject to certain conditions, to enable each Non-Aggregated Holder to treat securities of Hydro One that it owns or controls separately from securities of Hydro One owned or controlled by the other Non-Aggregated Holders for purposes of certain takeover bid, early warning reporting, insider reporting and control person distribution rules and certain distribution restrictions under Canadian securities laws. Hydro One was also granted relief permitting it to rely solely on insider reports and early warning reports filed by Non-Aggregated Holders when reporting beneficial ownership or control or direction over securities in an information circular or annual information form in respect of securities beneficially owned or controlled by any Non-Aggregated Holder, subject to certain conditions.

Agreement to Acquire Avista Corporation

In July 2017, Hydro One reached an agreement to acquire Avista Corporation, a utility headquartered in Spokane, Washington, for approximately U.S. $5.3 billion in an all-cash transaction, comprised of an equity purchase price of U.S. $3.4 billion and the assumption of U.S. $1.9 billion of debt. The closing of the proposed acquisition of Avista Corporation by Hydro One Limited (the “Merger”) was subject to receipt of certain regulatory and government approvals, and the satisfaction of customary closing conditions.

In September 2017, Hydro One and Avista Corporation filed applications with certain state utility commissions, as well as with the Federal Energy Regulatory Commission, requesting regulatory approval of the Merger. In December 2018 and January 2019, state utility commissions for Washington and Idaho, respectively, denied the Merger. In January 2019, Hydro One and Avista Corporation mutually terminated the Merger Agreement. See “General Development of the Business – Chronological Development of the Business – 2019 – Termination of Merger Agreement with Avista Corporation” for more information.

Convertible Debenture Offering

In August 2017, in connection with the acquisition of Avista Corporation, Hydro One Limited and its wholly-owned subsidiary, 2582764 Ontario Inc. (the “Selling Debentureholder”), completed the sale of $1.54 billion aggregate principal amount of 4.00% convertible unsecured subordinated debentures (the “Debentures”) represented by instalment receipts. See “General Development of the Business – Chronological Development of the Business – 2019 – Redemption of Convertible Debentures Represented by Instalment Receipts” and “Description of Capital Structure – Convertible Debentures and Instalment Receipts” for more information.

First Nations and Hydro One Limited Shares

In December 2017, the Province sold approximately 14 million common shares of Hydro One Limited to OFN Power Holdings LP, a limited partnership wholly-owned by Ontario First Nations Sovereign Wealth LP, which is in turn owned by 129 First Nations in Ontario. This represented approximately 2.4% of the outstanding common shares of Hydro One Limited owned by the Province. Following this transaction, the Province owned approximately 47.4% common shares of the Company. Hydro One Limited was not a party to this transaction and did not receive any proceeds from the sale of the shares by the Province.

2018

Directors and Executive Officers

In July 2018, Hydro One Limited, on behalf of itself and its wholly owned subsidiary Hydro One Inc., announced that it had entered into an agreement with the Province (the “Letter Agreement”) for the purpose of the orderly replacement of the boards of directors of both companies and for the retirement of Mayo Schmidt as the CEO.

In accordance with the Letter Agreement, Hydro One has agreed to consult with the Province in respect of future matters of executive compensation. In addition, the then-existing Hydro One Limited and Hydro One Inc. boards of directors volunteered and agreed to immediately reduce board compensation to the levels contemplated by the pre-January 1, 2018 director compensation policy. The then-existing Hydro One Limited and Hydro One Inc. boards of directors also volunteered and agreed to forego any compensation for their service after June 30, 2018. Hydro One Limited also announced the appointment of Paul Dobson as Acting President and CEO of Hydro One Limited and Hydro One Inc. effective July 11, 2018 (prior to this appointment, Mr. Dobson was CFO of Hydro One Limited and Hydro One Inc.).

In August 2018, Hydro One Limited announced a new board of directors. The directors of Hydro One Limited and Hydro One Inc. are the same in accordance with the provisions of the Governance Agreement. Four directors were nominated by the Province, Hydro One Limited’s largest shareholder, and six directors were nominated by an ad hoc nominating committee of Hydro One Limited’s three largest shareholders excluding the Province. Each of the directors appointed were independent of both Hydro One Limited and the Province in accordance with the Governance Agreement.

Between July 2018 and April 2019, most of Hydro One Limited and Hydro One Inc.’s executive officers departed. Effective September 6, 2018, Tom Woods was appointed as Chair of the boards of directors of Hydro One Limited and Hydro One Inc. Also effective September 6, 2018, Chris Lopez (previously Senior Vice President, Finance of HONI) was appointed as Acting CFO of Hydro One Limited and Hydro One Inc. Mr. Lopez was subsequently appointed CFO of Hydro One Limited and Hydro One Inc. effective May 9, 2019.

See “Directors and Officers” and “Agreements with Principal Shareholder – Governance Agreement” for more information.

The Avista Corporation Merger

In December 2018, the Washington Utilities and Transportation Commission denied the Merger. Hydro One and Avista Corporation filed a petition requesting reconsideration of the denial, but in January 2019 the Washington Utilities and Transportation Commission declined to hear the petition. In January 2019, the Idaho Public Utilities Commission also denied the Merger.

In January 2019, Hydro One and Avista Corporation mutually terminated the Merger Agreement. See “General Development of the Business – Chronological Development of the Business – 2019 – Termination of Merger Agreement with Avista Corporation” for more information.

Financing the Merger

On November 23, 2018, Hydro One Holdings Limited (“HOHL”), an indirect wholly-owned subsidiary of Hydro One Limited, filed a U.S. debt short form base shelf prospectus with securities regulatory authorities in Canada and the United States for the purposes of, but not limited to, funding a portion of the cash purchase price of the Merger (“U.S. Debt Prospectus”). The U.S. Debt Prospectus allows HOHL to offer, from time to time in one or more public offerings, up to U.S. $3.0 billion of debt securities, unconditionally guaranteed by Hydro One Limited, during the 25-month period ending December 23, 2020. In order to facilitate funding for the Merger, on June 8, 2018, HOHL, as issuer, and Hydro One Limited, as guarantor, entered into a trust indenture (the “HOHL Indenture”) with Computershare Company, N.A., as United States trustee, and Computershare Company of Canada, as Canadian trustee, governing the issuance by HOHL of unsecured debentures, notes or other evidences of indebtedness in one or more series, unconditionally guaranteed as to payment by Hydro One Limited. To date, no debt has been issued under the HOHL Indenture.

In February 2019, the Debentures issued pursuant to the August 2017 offering were redeemed. See “General Development of the Business – Chronological Development of the Business – 2019 – Redemption of Convertible Debentures Represented by Instalment Receipts” for more information.

Universal Base Shelf Prospectus

On June 18, 2018, Hydro One Limited filed a universal short form base shelf prospectus in Canada to replace the universal base shelf prospectus that expired in April 2018. The universal short form base shelf prospectus allows Hydro One Limited to offer, from time to time in one or more public offerings, up to $4.0 billion of debt, equity or other securities, or any combination thereof, during the 25-month period ending July 18, 2020.

Exemptive Relief – U.S. GAAP

In March 2018, Hydro One Limited was granted exemptive relief by securities regulators in each province and territory of Canada, allowing Hydro One Limited to continue reporting its financial results in accordance with U.S. GAAP. This exemptive relief will remain in effect until the earlier of: (i) January 1, 2024; (ii) the first day of Hydro One Limited’s financial year that commences after Hydro One Limited ceases to have activities subject to rate regulation; and (iii) the effective date prescribed by the International Accounting Standards Board for the mandatory application of a standard within International Financial Reporting Standards specific to entities with activities subject to rate regulation.

Agreement to Acquire Orillia Power

In August 2016, Hydro One Inc. reached an agreement to acquire Orillia Power, an electricity distribution company located in Simcoe County, Ontario, from the Corporation of the City of Orillia for approximately $41 million, including the assumption of approximately $15 million in outstanding indebtedness and regulatory liabilities, subject to closing adjustments. In April 2018, the OEB issued a decision denying Hydro One Inc.’s proposed acquisition of Orillia Power. In May 2018, Hydro One Inc. and Orillia Power filed a motion to review and vary the OEB’s decision, and in August 2018, the OEB upheld its April 2018 decision denying the acquisition. In September 2018, Hydro One Inc. filed a new MAAD application with the OEB to acquire Orillia Power. The acquisition is subject to the satisfaction of customary closing conditions as well as approval by the OEB. See “Business of Hydro One – Distribution Business Segment – Acquisitions – Agreement to Acquire Orillia Power” for more information.

Agreement to Acquire the Business and Distribution Assets of Peterborough Distribution Inc.

In July 2018, Hydro One Inc. reached an agreement to acquire the business and distribution assets of Peterborough Distribution Inc., an electricity distribution company located in the County of Peterborough, from the Corporation of the City of Peterborough. Hydro One Inc. will pay the Corporation of the City of Peterborough approximately $105 million, subject to closing adjustments. The acquisition is subject to the satisfaction of customary closing conditions as well as approval by the OEB. See “Business of Hydro One – Distribution Business Segment – Acquisitions – Agreement to Acquire the Business and Distribution Assets of Peterborough Distribution Inc.” for more information.

HOSSM

In October 2016, following OEB approval, Hydro One completed the acquisition of Great Lakes Power, an Ontario regulated electricity transmission business operating along the eastern shore of Lake Superior, north and east of Sault Ste. Marie, Ontario. In January 2017, the name Great Lakes Power was changed to HOSSM. In October 2018, HOSSM was operationally integrated into HONI, including its employees and transmission customers. HOSSM is expected to exist as a separate affiliate until 2023.

Niagara Reinforcement Limited Partnership – 2018

In September 2018, the Niagara Reinforcement Limited Partnership (“NRLP”) was formed for the purpose of owning a new 230 kV transmission line in the Niagara region (the “Niagara Line”) to enable generators in the Niagara area to connect to load centres of the Greater Toronto and Hamilton areas.

In September 2018, HONI filed a transmission licence application with the OEB for NRLP. In October 2018, HONI filed two other applications with the OEB relating to NRLP requesting approval for HONI to sell the Niagara Line to NRLP, and approval of interim rates to include in the 2019 uniform transmission rates. On December 20, 2018, the OEB issued a decision finding that the request for approval for an interim revenue requirement effective January 1, 2019 was premature but indicated that there would be an opportunity to adjudicate the matter at a later date. See “Business of Hydro One – Transmission Business Segment – Regulation – Recent Transmission Rate Applications - Niagara Reinforcement Limited Partnership” for more information.

2019

Termination of Merger Agreement with Avista Corporation

In January 2019, following denials of the Merger by the Washington Utilities and Transportation Commission and the Idaho Public Utilities Commission, Hydro One Limited and Avista Corporation announced that they mutually agreed to terminate the Merger Agreement.

As required under the Merger Agreement, Hydro One Limited paid Avista Corporation a U.S. $103 million termination fee as a result of the termination of the Merger Agreement. A copy of the Termination Agreement is available on SEDAR at www.sedar.com.

Redemption of Convertible Debentures Represented by Instalment Receipts

In January 2019, Hydro One Limited announced that, as a result of the termination of the Merger Agreement, it would redeem (the “Redemption”) all of its outstanding $1.54 billion Debentures represented by instalment receipts. On February 8, 2019, the Redemption occurred pursuant to the terms of the trust indenture pursuant to which the Debentures were issued and the instalment receipt and pledge agreement governing the instalment receipts. On February 8, 2019, the instalment receipts, which were listed and posted for trading on the TSX under the symbol “H.IR”, were delisted.

Niagara Reinforcement Limited Partnership – 2019

In January 2019, construction on the Niagara Line was halted due to a land dispute with the Haudenosaunee Confederacy Chiefs Council (“HCCC”). In March 2019, HONI filed a letter with the OEB requesting that the three previously-filed applications be heard together once the land dispute was resolved. Also in March 2019, the OEB put the NRLP applications in abeyance per HONI’s request. HONI filed a Statement of Claim

with the Ontario Superior Court of Justice for injunctive relief against members of the HCCC, among others. In July 2019, HONI was granted the injunction and resumed construction of the Niagara Line shortly thereafter. The construction of the Niagara Line was completed at the end of August 2019.

In August 2019, HONI filed an update to the three previously-filed OEB applications and asked that the OEB resume adjudication of the applications. In September 2019, the OEB granted NRLP a transmission licence and also granted HONI leave to sell the Niagara Line to NRLP.

In September 2019, the Niagara Line was transferred from HONI to NRLP for $119 million and operation of the Niagara Line was contracted to HONI. Subsequently, on the same date, HONI sold to the Six Nations of the Grand River Development Corporation and, through a trust, to the Mississaugas of the Credit First Nation a 25.0% and 0.1%, respectively, equity interest in NRLP for total consideration of approximately $12 million, representing the fair value of the equity interest acquired. At the time of this sale, the Mississaugas of the Credit First Nation received an option to purchase an additional 19.9% equity interest in NRLP from HONI at a price based on the value of the Niagara Line on the date of closing. The Mississaugas of the Credit First Nation exercised this option in December 2019, for a consideration of approximately $9 million. This purchase transaction closed in January 2020. Following this transaction, the Company’s interest in NRLP was reduced to 55% with the Six Nations of the Grand River Development Corporation and, through a trust, the Mississaugas of the Credit First Nation owning 25% and 20%, respectively, of equity interest in NRLP. See “Business of Hydro One – Transmission Business Segment – Regulation – Recent Transmission Rate Applications - Niagara Reinforcement Limited Partnership” for more information.

We will make it easier to do business with Hydro One by strengthening the customer experience through innovative customer-centric practices. We will help our customers make informed decisions with deeper insights and leverage our position as energy experts. We will expand access to energy offerings to become the provider of choice to our customers.

•	Innovate And Grow The Business

We will continue to invest responsibly in our core transmission and distribution business. In addition, we will pursue incremental regulated and unregulated business opportunities through innovation and our focused presence in Ontario.

General Development of the Business

In addition to the chronological development of the business, the following general developments in the business have occurred and continue to be relevant.

Customer Focus

Our continued focus on customer service remains a critical aspect of our success as a Company. Greater corporate accountability for performance outcomes, and company-wide improvements in productivity and efficiency, align with our customers’ expectations of how Hydro One should operate. Hydro One intends to continue to offer affordable and reliable electricity, advocate for our customers and empower them to make informed decisions about their energy usage, and respond to emerging customer needs.

Customer Service

Hydro One is committed to delivering value to its customers by becoming easier to do business with, being available when customers need assistance, and always staying connected. This includes specific, measurable commitments that encompass all areas of service. This focus on customer service resulted in improved satisfaction survey scores in 2019. Residential and small business customer satisfaction scores were the highest in ten years at 86%, transmission customer satisfaction saw a slight decrease from 2018 results, from 90% to 87%, while customer satisfaction for commercial and industrial customers was at 79%, reflecting a company-wide dedication to improving customer service. Another area of focus has been to shift customer interactions to digital channels to meet customers’ needs while reducing operational costs and increasing customer satisfaction. Hydro One is on a multi-year journey to transform the customer experience by creating digital channels that enhance existing services, introduce new services and offer innovative solutions to better anticipate and meet the needs of customers.

Review of Operations

Hydro One has been focused on the identification of opportunities for improved corporate performance and the development of strategies to drive more efficient, cost-effective operations. Hydro One conducts regular reviews of key corporate activities and programs, covering areas such as construction services and project management practices, asset deployment and controls, information technology and cybersecurity, vegetation management practices, fleet services and utilization, supply chain management and business continuity planning. Operational and cost improvements across work planning and execution have already been observed and implemented. Hydro One has included productivity cost savings in its applications before the OEB.

Sustainability and Environmental Reporting

In August 2019, Hydro One Limited published its 2018 Sustainability Report, highlighting its progress in 2018 and its plans for future years. The report reviews Hydro One’s performance in five key areas: putting customers first, management of environmental impacts, employees and workplace, a commitment to supporting stronger communities, and investments to improve service reliability and the long-term viability of the Company. In September 2019, Hydro One Limited outlined its actions to address climate change in its 2018 submission to the Carbon Disclosure Project, an organization which supports the disclosure of the environmental impact of major corporations.

BUSINESS OF HYDRO ONE

Segments

Through its wholly-owned subsidiary Hydro One Inc., Hydro One is Ontario’s largest electricity transmission and distribution utility with approximately $27.1 billion in assets and 2019 revenues of approximately $6.5 billion. Hydro One owns and operates substantially all of Ontario’s electricity transmission network and is the largest electricity distributor in Ontario by number of customers. The Company’s regulated transmission and distribution operations are owned by Hydro One Inc. Hydro One delivers electricity safely and reliably to approximately 1.4 million customers across the province of Ontario, and to large industrial customers and municipal utilities. Hydro One Inc. owns and operates approximately 30,000 circuit kilometres of high-voltage transmission lines and approximately 123,000 circuit kilometres of primary low-voltage distribution lines.

Hydro One has three segments: (i) transmission business; (ii) distribution business; and (iii) other. Each of the three segments is described below.

Hydro One’s transmission and distribution businesses are both operated primarily through HONI. This allows both businesses to utilize common operating platforms, technology, work processes, equipment and field staff and thereby take advantage of operating efficiencies and synergies. For regulatory purposes, HONI has historically filed separate rate applications with the OEB for each of its licensed transmission and distribution businesses. A single application will be filed for transmission and distribution for the period 2023 to 2027.

Transmission Business Segment

Overview

Hydro One’s transmission business consists of owning, operating and maintaining Hydro One’s transmission system, which accounts for approximately 98% of Ontario’s transmission capacity based on revenue approved by the OEB. All of the Company’s transmission business is carried out through HONI, a wholly-owned subsidiary of Hydro One Inc., through its subsidiary HOSSM (formerly Great Lakes Power), as well as through the Company’s approximately 66% interest in B2M Limited Partnership and 75% interest in NRLP. Hydro One’s 75% interest in NRLP was reduced to 55% following the closing of a purchase transaction in January 2020. Hydro One’s transmission business represented approximately 56% of its total assets as at December 31, 2019, and accounted for approximately 49% of its total revenue in 2019, net of purchased power and 52% of its total revenue in 2018, net of purchased power.

The Company’s transmission business is a rate-regulated business that earns revenues mainly from charging transmission rates that are subject to approval by the OEB. The Company’s transmission rates are generally determined using a performance-based model, which typically includes a cost-of-service base year. Transmission rates are collected by the IESO and are remitted by the IESO to Hydro One on a monthly basis, which means that Hydro One’s transmission business has no direct exposure to end-customer counterparty risk.

Transmission rates are based on monthly peak electricity demand across Hydro One’s transmission network. This gives rise to seasonal variations in Hydro One’s transmission revenues, which are generally higher in the summer and winter due to increased demand, and lower during other periods of reduced demand. Hydro One’s transmission revenues also include revenues associated with exporting energy to markets outside of Ontario. Ancillary revenue includes revenues from providing maintenance services to generators and from third-party land use.

Business

The Company’s transmission system serves substantially all of Ontario and transported approximately 135 TWh of energy throughout the province in 2019. Hydro One’s transmission customers consist of 38 local distribution companies (including Hydro One’s own distribution business) and 83 large industrial customers connected directly to the transmission network, including automotive, manufacturing, chemical and natural resources businesses. Electricity delivered over the Company’s transmission network is supplied by 133 generators in Ontario and electricity imported into the province through interties. Interties are transmission interconnections between neighbouring electric systems that allow power to be imported and exported.

The high voltage power lines in Hydro One’s transmission network are categorized as either lines which form part of the “bulk electricity system” or “area supply lines”. Power lines which form part of the bulk electricity system typically connect major generation facilities with transmission stations and often cover

long distances, while area supply lines serve a local region. Ontario’s transmission system is connected to the transmission systems of Manitoba, Michigan, Minnesota, New York and Quebec through the use of interties, allowing for the import and export of electricity to and from Ontario.

Hydro One’s transmission assets were approximately $15 billion as at December 31, 2019 and include transmission stations, transmission lines, a control centre and telecommunications facilities. Hydro One has approximately 309 in-service transmission stations and approximately 30,000 circuit kilometres of high voltage lines whose major components include cables, conductors and wood or steel support structures. All of these lines are overhead power lines except for approximately 270 circuit kilometres of underground cables located in primarily urban areas.

Hydro One’s transmission network is managed from a central location. This centre monitors and controls the Company’s entire transmission network, and has the capability to remotely monitor and operate transmission equipment, respond to alarms and contingencies and restore and reroute interrupted power. There is also a backup facility which would be staffed in the event of an evacuation of the centre. In September 2019, Hydro One Inc. announced plans to build a new Ontario grid control centre.

Hydro One uses telecommunications systems for the protection and operation of its transmission and distribution networks. These systems are subject to very stringent reliability and security requirements, which help the Company meet its reliability obligations and facilitate the restoration of power following service interruptions.

B2M Limited Partnership is Hydro One’s partnership with the Saugeen Ojibway Nation with respect to the Bruce-to-Milton transmission line. B2M Limited Partnership owns the transmission line assets relating to two circuits between Bruce TS and Milton TS, while Hydro One owns the transmission stations where the lines terminate. Hydro One maintains and operates the Bruce-to-Milton line and has an approximately 66% economic interest in the partnership.

NRLP is Hydro One’s partnership with Six Nations of the Grand River Development Corporation and, through a trust, the Mississaugas of the Credit First Nation. NRLP owns the Niagara Line. Hydro One maintains and operates the Niagara Line, and had a 75% interest in the partnership at year end, which reduced to 55% following the closing of the purchase transaction in January 2020. See “General Development of the Business – Chronological Development of the Business – 2019 – Niagara Reinforcement Limited Partnership – 2019” for more information.

In 2018, Hydro One completed the operational integration of HOSSM (formerly Great Lakes Power), which was acquired in October 2016. See “General Development of the Business – Chronological Development of the Business – 2018 – HOSSM” for more information.

Regulation

Transmission Rate Setting

The OEB provides two revenue plan options for transmission rates in Ontario: the Custom Incentive Rate Setting Plan (the “Custom IR Method”) and the Incentive-Based Revenue Index Rate Setting Plan (the “Revenue Cap Index”).

Under the Revenue Cap Index, the first year’s revenue requirement reflects the transmitter’s cost of service; and annually thereafter, this amount is subject to a formulaic increase reflecting inflation, partially offset by a productivity factor. The revenue requirement in these subsequent years is set on the assumption that the transmitter will achieve efficiency or productivity improvements to offset the productivity factor imposed by the regulator. Under the Custom IR Method, a similar methodology to the Revenue Cap Index may be used; however, applications are multi-year and are designed to reflect a transmitter-specific revenue trend for the application term. For example, a transmitter may request incremental capital funding beyond amounts established in the base year revenue requirement.

The OEB sets transmission rates based on a two-step process. First, all transmitters apply to the OEB for the approval of their revenue requirements. Second, the OEB aggregates the total revenue requirements of all transmitters in Ontario and applies a formula to arrive at a single set of rates that are charged to ratepayers for the three types of transmission services applicable in Ontario, namely: network services, line connection services and transformation connection services. The three separate rates charged for these services are the same for all transmitters and are referred to as “uniform transmission rates”. Uniform transmission rates for all transmitters are set by the OEB on an annual basis, using the revenue requirements set out in the most recent rate decision issued for each transmitter.

The filing requirements for transmitters mandate the integration of core RRF (defined below under “Business of Hydro One – Distribution Business Segment – Regulation – Distribution Rates”) concepts into revenue requirement applications. Transmitters applying for revenue requirements under the Custom IR Method or Revenue Cap Index must include: (i) evidence of the continuous improvement and efficiency gains anticipated to be achieved over the rate term; (ii) a mechanism to protect ratepayers in the event of earnings significantly in excess of the regulatory net income supported by the return on equity established in the approved revenue requirement; and (iii) proposed performance metrics applicable to their individual circumstances. A key component of rate–setting under the RRF is benchmarking evidence to support cost forecasts and system planning proposals.

Recent Transmission Rate Applications

HONI, B2M Limited Partnership, HOSSM and NRLP file separate applications to the OEB for the approval of their transmission revenue requirement for transmission services.

HONI

In September 2017, the OEB issued its decision on HONI’s application for 2017-2018 transmission revenue requirement. In the decision, the OEB concluded that the net deferred tax asset resulting from the transition from the payments in lieu of tax regime under the Electricity Act to the federal and provincial tax regimes in connection with the 2015 initial public offering should not accrue entirely to Hydro One Limited’s shareholders, but rather a portion should be shared with HONI’s ratepayers. The OEB proposed a basis for sharing a portion of the tax savings resulting from the deferred tax asset with HONI’s ratepayers by reducing the amount of taxes approved for recovery in HONI’s 2017-2018 transmission revenue requirement. In November 2017, the OEB issued a decision and order that established the portion of the tax savings that should be shared with HONI’s ratepayers.

In October 2017, HONI filed with the OEB a motion to review and vary the OEB’s decision, and filed an appeal with the Ontario Divisional Court. The motion, among other things, sought allocation to Hydro One Limited’s shareholders of the full amount of the future tax savings arising from the deferred tax asset. In both the motion and the appeal, HONI’s position was that the OEB made errors of fact and law in its determination of the allocation of the tax savings between Hydro One Limited’s shareholders and HONI’s ratepayers. An OEB hearing of the merits of the motion was held in February 2018. In August 2018, the OEB granted the motion and returned the portion of the decision relating to the deferred tax asset to an OEB panel for reconsideration. In March 2019, the OEB upheld its original decision on the allocation of the deferred tax asset between Hydro One Limited’s shareholders and HONI’s ratepayers. As a result, the Company has recorded an $867 million one-time decrease in net income as a reversal of revenues of $68 million, and a charge to deferred tax expense of $799 million, which is expected to result in an annual decrease to funds from operations in the range of $50 million to $60 million in the near term, and this range will decline over time. In April 2019, HONI filed an appeal with the Ontario Divisional Court with respect to the OEB’s deferred tax asset decision. The appeal was heard in November 2019, and a decision is pending. See the Annual MD&A under the subheading “Risk Management and Risk Factors – Risks Relating to Hydro One’s Business – Regulatory Risks and Risks Relating to Hydro One’s Revenues – Risks Relating to Regulatory Treatment of Deferred Tax Asset” for a description of related risks.

In March 2018, the OEB requested that HONI file the transmission revenue requirement application for a four-year test period from 2019 to 2022.

A one-year inflation-based application for the 2019 transmission revenue requirement was filed with the OEB in October 2018. In December 2018, the OEB issued a decision declaring HONI’s 2018 transmission revenue requirement of approximately $1,521 million and specifying the 2019 uniform transmission rates, both interim and effective as of January 1, 2019. In April 2019, the OEB issued its decision on HONI’s transmission rate application and set the revenue index at 1.4% on a final basis effective May 1, 2019.

In March 2019, HONI filed a three-year custom incentive rate application with the OEB for its 2020-2022 transmission revenue requirements. The application requested the OEB’s approval of revenue requirements

of $1,623 million for 2020. In June 2019, HONI filed updates to the application reflecting recent financial results and other adjustments. The hearing concluded in November 2019. The OEB decision is pending.

On December 10, 2019, the OEB approved HONI’s 2019 transmission revenue requirement and charges as interim effective January 1, 2020 until the new transmission revenue requirement and charges are approved by the OEB.

The OEB has also requested that HONI file a single application for distribution rates (including Hydro One Remote Communities Inc.) and transmission revenue requirement for the period from 2023 to 2027. HONI intends to comply with this request. See also “Business of Hydro One – Distribution Business Segment – Regulation – Recent Distribution Rate Applications – HONI”.

B2M Limited Partnership

In December 2015, the OEB approved B2M Limited Partnership’s revenue requirement for years 2015 to 2019, subject to annual updates in each of 2016, 2017, 2018 and 2019 to adjust its revenue requirement for the following year consistent with the OEB’s updated cost of capital parameters. In May 2018, the OEB issued its decision and rate order on B2M Limited Partnership’s 2018 transmission application reflecting a revenue requirement of $36 million, effective January 1, 2018.

In November 2018, a revised 2019 revenue requirement using the updated cost of capital parameters was filed with the OEB. In December 2018, the OEB issued its decision on uniform transmission rates effective January 1, 2019, approving the requested 2019 revenue requirement of approximately $33 million.

In July 2019, B2M Limited Partnership filed a transmission rate application for 2020-2024, seeking a base revenue requirement of $36 million for 2020, and a 1.4% revenue cap escalator index for 2021 to 2024. On December 9, 2019, B2M Limited Partnership reached a settlement on all issues with OEB staff and Intervenors on the 5-year revenue cap rate application for 2020-2024 to be effective January 1, 2020. The settlement accepts all of B2M Limited Partnership’s cost submissions, but includes additional reliability reporting and a capital adjustment (reduction) factor of 0.6% to account for the lower rate base value. On January 6, 2020, the settlement agreement was filed with the OEB for approval, which was granted on January 16, 2020.

HOSSM

HOSSM is under a ten-year deferred rebasing period for years 2017-2026, following receipt of approval by the OEB of Hydro One’s acquisition of HOSSM in October 2016. HOSSM’s 2016 approved revenue requirement of $41 million remained in effect for 2017 and 2018.

In July 2018, HOSSM filed a 2019 application to allow for inflationary increase (“revenue cap escalator factor”) to its previously approved revenue requirement. The revenue cap escalator factor is designed to add inflationary increases to the revenue requirement on an annual basis. In June 2019, the OEB approved the revenue cap escalator index at 1.1% (net) which was applied to HOSSM's base revenue requirement for

2019, effective February 1, 2019, and also approved the 2019-2026 revenue cap framework. In December 2019, the OEB issued a decision on HOSSM’s request for transmission revenue requirement for 2020. The OEB approved the revenue cap adjustment requesting an increase to the 2020 revenue requirement of 1.5% (inflation factor of 1.8% less stretch factor of 0.3%).

Niagara Reinforcement Limited Partnership

In September 2019, the OEB granted NRLP a transmission licence and granted HONI leave to sell the Niagara Line to NRLP. Also in September 2019, the OEB approved NRLP’s request to establish a deferral account to record NRLP’s 2019 revenue requirement prior to its inclusion in the uniform transmission rates. In October 2019, NRLP filed its revenue cap incentive rate application for 2020-2024. In December 2019, the OEB approved NRLP’s proposed 2020 revenue requirement of $9 million as interim effective January 1, 2020. See “General Development of the Business – Chronological Development of the Business – 2018 – Niagara Reinforcement Limited Partnership – 2018” and “General Development of the Business – Chronological Development of the Business – 2019 – Niagara Reinforcement Limited Partnership – 2019” for more information.

Reliability Standards for Transmission

The Company’s transmission business is required to comply with various mandatory regulations for transmission reliability, including mandatory standards, directories and market rules established by NERC, NPCC, and the IESO, which are international, regional and Ontario reliability regulatory authorities, respectively, involved in regulating, promoting and otherwise improving the reliability of transmission networks in North America. Hydro One’s compliance with these reliability regulations is enforced by both the IESO and the Canadian Energy Regulator.

Among the various regulations, NERC has established a set of currently enforced standards and continues to issue new and revised standards to ensure that utilities and other users, owners and operators of the bulk electricity system in North America implement and sustain preventive, detective and corrective measures to mitigate cyber and physical security risks to critical infrastructure. Hydro One’s physical, electronic and information security measures have been and are being upgraded to meet these revised requirements. Hydro One expects to continue to perform additional work and incur further costs to comply with these and other reliability requirements. Hydro One anticipates that these costs will be incurred annually over a number of years and will be recovered in rates. See the Annual MD&A under the subheadings “Risk Management and Risk Factors – Risks Relating to Hydro One’s Business – Compliance with Laws and Regulations”, “Risk Management and Risk Factors – Risks Relating to Hydro One’s Business – Risk Associated with Information Technology, Operational Technology Infrastructure and Data Security” and “Risk Management and Risk Factors – Risks Relating to Hydro One’s Business –Risks Relating to Asset Condition, Capital Projects and Innovation” for more information.

Regional Planning

The OEB oversees regional planning processes to ensure that transmission and distribution investments are coordinated at a regional level. One of the OEB objectives for regional planning is to review and/or rely on regional planning studies and reports to support rate applications submitted by transmitters and distributors and “leave to construct” applications submitted by transmitters. In Ontario, the first phase of the regional planning process is led by the transmitter responsible for a particular geographic region. For this purpose, the province is divided into 21 regions. As the largest transmitter in Ontario, Hydro One plays a key role in the regional planning process and is responsible for leading the regional planning process in 20 of the 21 designated regions. The first cycle of the regional planning process was completed in 2017. The second cycle of the regional planning process is currently in progress. Recommended transmission and distribution investments from the regional planning process will be undertaken by the transmitter responsible for each region and by distributors in each region for their respective service territories.

In conducting regional planning, Hydro One works closely with the IESO and all distributors in the region through study teams to jointly identify needs and develop transmission and distribution investment options. Hydro One also coordinates with the IESO on its Integrated Regional Resource Planning which is another phase of the regional planning process.

Capital Expenditures

The Company anticipates that it will spend in the range of approximately $1,181 million to $1,382 million per year, over the next five years, on capital expenditures relating to its transmission business. The Company’s capital expenditure plans are included in Hydro One’s applications to the OEB for transmission rates and are subject to approval by the OEB. See “Capital Investments – Future Capital Investments” and “Capital Investments – Major Transmission Capital Investment Projects” in the Annual MD&A for more information on future capital expenditures.

The Company incurs both sustaining capital expenditures and development capital expenditures. Sustaining capital expenditures are those investments required to replace or refurbish our assets and facilities to ensure that the transmission system continues to function as originally designed. Hydro One’s plans to maintain, refurbish or replace existing assets are based upon risk assessments, asset condition assessments and end-of-service life criteria specific to each type of asset. Priorities are assigned to each type of investment based upon the extent of the risks that it mitigates.

Investments to sustain Hydro One’s transmission assets are critical to maintain the safety, reliability and integrity of its existing transmission network. Hydro One’s sustainment capital plan is designed to maintain Hydro One’s transmission reliability performance, as determined by measures such as the average length (in minutes) of unplanned interruptions per delivery point. The Company expects that significant investments will be required to sustain its existing infrastructure over the long term.

The Company’s development capital expenditure plan is designed to address Ontario’s expected change in the generation profile, accommodate load growth in areas throughout Ontario and support the economic growth in Ontario including industrial and agricultural growth and connection of the remote communities in the northern part of the province. Development capital expenditures include those investments required to develop and build new large-scale projects such as new transmission lines and stations as well as smaller projects such as transmission line or station reinforcements, extensions or additions to connect generation or serve load.

The Company engages with various stakeholders, including its customers, as it develops its capital plans. It also engages affected communities and parties who may be impacted by individual projects. The Company also consults with Indigenous communities whose rights may be affected by its projects.

Competitive Conditions

Within our principal market of Ontario, the Company operates and maintains substantially all of the transmission system. Competition for transmission services in Ontario is currently limited. The adoption by the OEB of uniform transmission rates that apply to all transmitters also reduces the financial incentive for customers to seek alternative transmission providers, since each transmitter in Ontario charges the same uniform rate for transmission services. Hydro One competes with other transmitters for the opportunity to build new large-scale transmission facilities in Ontario. The competitive process was amended in 2016 by the proclamation of the Energy Statute Law Amendment Act to allow for the selection of a transmitter outside the existing competitive process. The 2017 Long-Term Energy Plan directed the IESO to develop a transmission procurement process that is clear, cost-effective, efficient and able to respond to changing policy, market and system needs. This process is currently underway.

Hydro One does not compete with other transmitters with respect to investments which are made to sustain or develop its existing transmission infrastructure.

Distribution Business Segment

Overview

Hydro One’s distribution business consists of owning, operating and maintaining Hydro One’s distribution system, which Hydro One, through Hydro One Inc., owns primarily through its wholly-owned subsidiary, HONI, the largest local distribution company in Ontario. The Company’s distribution system is also the largest in Ontario. The Company’s distribution business is a rate-regulated business that earns revenues mainly by charging distribution rates that are subject to approval by the OEB. Hydro One’s distribution business also includes the business of its wholly-owned subsidiary, Hydro One Remote Communities Inc., which supplies electricity to customers in remote communities in northern Ontario. The Company’s distribution rates are generally determined using a performance-based model, except for the distribution rates of Hydro One Remote Communities Inc., which are set on a cost-recovery basis and do not include a return on equity.

Hydro One’s distribution business represented approximately 37% of its total assets as at December 31, 2019, and accounted for approximately 50% of its total revenue in 2019, net of purchased power and 47% of its total revenue in 2018, net of purchased power. Distribution revenues include distribution rates approved by the OEB and amounts to reimburse Hydro One for the cost of purchasing electricity delivered to its distribution customers. Distribution revenues also include minor ancillary service revenues, such as fees related to the joint use of the Company’s distribution poles by participants in the telecommunications and cable television industries, as well as miscellaneous charges such as charges for late payments.

As at December 31, 2019, Hydro One’s distribution assets were approximately $10 billion.

Business

Hydro One delivers electricity through its distribution network to approximately 1.4 million residential and business customers, most of whom are located in rural areas, as well as 47 local distribution companies (including Hydro One’s own distribution business).

Hydro One’s distribution system includes approximately 123,000 circuit kilometres of primary low-voltage distribution lines and approximately 1,000 distribution and regulating stations. Other distribution assets include poles, transformers, service centres and equipment.

Hydro One’s distribution system services a predominantly rural territory. As a result of the lower population density in the Company’s service territory, the Company’s costs to provide distribution services may be higher than those of distributors who service urban areas. Furthermore, unlike the distribution systems found in urban areas, most of Hydro One’s distribution system was not designed with redundancy, to be interconnected in loops with other distribution lines, with the result that interruptions experienced at any point along a distribution line in Hydro One’s network can cause all customers downstream of the interruption point to lose power. Accordingly, the reliability of Hydro One’s distribution system is lower than that of local distribution companies which service urban territories that typically have redundancy built into their systems.

The Company engages in vegetation management activities to maintain the reliability of Hydro One’s distribution system on a preventive basis and to protect public health and safety. This consists of the trimming or removal of trees to lower the risk of contact with distribution lines, thereby reducing the risk of power outages, and preventing potential injury to the public or employees. The Company’s monitoring systems assist with determining areas of priority and with system restoration. The Company relies on its local line crews for these restoration activities.

Hydro One’s distribution business is involved in the connection of new sources of electricity generation, including renewable energy. Hydro One invests in upgrades and modifications to its distribution system to accommodate these new sources of generation and ensure the continued reliability of its distribution network. As at December 31, 2019, there were approximately 17,000 small, mid-size and large embedded generators connected to Hydro One’s distribution network, including approximately 16,000 generators with capacities

of up to 10 kW. As at December 31, 2019, Hydro One also had approximately 800 generators pending connection.

Hydro One has played a significant role in the installation of smart meters and the migration of distribution customers to time of use pricing in Ontario. Smart meters are regarded as an integral means of promoting a culture of conservation and allow customers to change their electricity consumption patterns and reduce their costs. Hydro One has completed all material activities associated with the implementation of smart meters and has transitioned the vast majority of its customers to time of use pricing.

Acquisitions

Agreement to Acquire Orillia Power

In August 2016, Hydro One Inc. reached an agreement to acquire Orillia Power, an electricity distribution company located in Simcoe County, Ontario, from the Corporation of the City of Orillia for approximately $41 million, including the assumption of approximately $15 million in outstanding indebtedness and regulatory liabilities, subject to closing adjustments. The acquisition is subject to the satisfaction of customary closing conditions as well as approval by the OEB. In April 2018, the OEB issued a decision denying Hydro One Inc.’s proposed acquisition of Orillia Power. Hydro One Inc. and Orillia Power filed a motion to review and vary the OEB’s decision, and in August 2018, the OEB issued a decision upholding its April 2018 decision to deny Hydro One Inc.’s proposed acquisition of Orillia Power. In September 2018, Hydro One Inc. filed a new MAAD application with the OEB to acquire Orillia Power. The evidence in this MAAD application has been updated to reflect current variables to costs and other metrics, as well as future cost structures pertaining to the acquired entity. In 2019, Hydro One filed supplemental evidence, and a technical conference and an oral hearing were held in respect of the acquisition. A decision by the OEB is pending.

Agreement to Acquire the Business and Distribution Assets of Peterborough Distribution Inc.

In July 2018, Hydro One Inc. reached an agreement to acquire the business and distribution assets of Peterborough Distribution Inc., an electricity distribution company located in the County of Peterborough, from the Corporation of the City of Peterborough. Hydro One Inc. will pay the Corporation of the City of Peterborough approximately $105 million, subject to closing adjustments. The acquisition is subject to the satisfaction of customary closing conditions as well as approval by the OEB and the Competition Bureau. In October 2018, Hydro One Inc. filed a MAAD application with the OEB for approval of the acquisition. In November 2018, the Competition Bureau issued a no-action letter, stating that it does not intend to take action against the acquisition. In 2019, Hydro One filed supplemental evidence, and a technical conference and an oral hearing were held in respect of the acquisition. A decision by the OEB is pending.

Regulation

Distribution Rates

Distribution rates in Ontario are determined using a performance-based model set out in the OEB’s Renewed Regulatory Framework for Electricity Distributors: A Performance-Based Approach, which is sometimes referred to as the “RRF”. Under the RRF, distributors in Ontario may choose one of three rate-setting methods, depending on their capital requirements: 4^th^ Generation Incentive Rate-Setting (now known as “Price Cap IR”), Custom IR Method, or Annual Incentive Rate-Setting Index.

The RRF contemplates that under the Price Cap IR method, a distributor will apply for the approval of its revenue requirement for an initial base year, reflecting the distributor’s cost of service. The revenue requirement for subsequent years is determined based on a formula that accounts for inflation and certain productivity factors set by the regulator. The revenue requirement in these subsequent years is set on the assumption that the distributor will achieve efficiency or productivity improvements to offset the productivity factor imposed by the regulator.

Under the Custom IR Method, a similar methodology to the Price Cap IR may be used; however, applications are multi-year and are designed to reflect a distributor-specific revenue trend for the application term. For example, a distributor may request incremental capital funding beyond amounts established in the base year revenue requirement.

The scope of applications under the Annual Incentive Rate-Setting Index option is limited to formulaic adjustments to prior year OEB-approved rates. The adjustment provides an increase based on inflation, partially offset by a productivity factor. Distributors under this plan do not have access to mechanisms for additional capital funding beyond the formulaic adjustment.

The RRF allows the distributor to retain all or a portion of the cost savings achieved in excess of the estimate established by the regulator during the period covered by the rate decision, subject to any sharing mechanisms that may be required by the OEB, as indicated in the decision of each rate application. This approach allows the distributor an ability to earn more than its allowed return on equity. The RRF also requires distributors to demonstrate certain performance outcomes, namely: customer focus, operational effectiveness, public policy responsiveness and financial performance. The OEB has indicated that customer focused outcomes and continuous performance improvements by distributors are central to the RRF framework objectives and are considered as part of a distributor rate application.

Performance measures are an important part of the RRF, and the OEB has established a standard performance scorecard for all distributors which is reported annually. Distributors may also propose additional performance measures for approval by the OEB. In its most recent distribution application, Hydro One submitted additional measures relating to areas that are of particular interest, such as customer service and reliability, as well as operational efficiency in key areas like pole replacements, distribution station

refurbishments and vegetation management. In subsequent rate applications, distributors are required to report to the OEB on their performance against the performance measures approved.

The OEB’s review process of the anticipated cost of service for providing distribution services under the RRF follows a process similar to that of a transmission rate application. Once the revenue requirement for distribution services is determined, it is allocated across the distributor’s customer rate classes using a methodology approved by the OEB resulting in the setting of individual rates for distribution services based on each customer rate class. Hydro One currently has 13 customer rate classes. Distribution rates in Ontario are not the same for all distributors and reflect the particular circumstances of each distributor, including its own costs of providing electricity service to its own particular customers. The OEB policy, A New Distribution Rate Design for Residential Electricity Customers, changes the current distribution rate design for residential customers (a combination of a fixed monthly rate and a variable charge) to a fixed monthly charge only. In December 2015, the OEB increased the transition period for certain customer classes of HONI to eight years to mitigate bill impacts. Implementation will be completed over the next four years for HONI’s residential customers, depending on rate class.

The OEB is considering possible changes to the design of rates for commercial industrial customers. Changes to rate design will not impact the total revenue to be collected from these customer classes.

Recent Distribution Rate Applications

The Company’s distribution rates, other than the distribution rates of Hydro One Remote Communities Inc., are determined by using a performance-based model.

HONI

In March 2017, HONI filed a custom application with the OEB for its 2018-2022 distribution rates. The application reflects the level of capital investments required to minimize degradation in overall system asset condition, to meet regulatory requirements, and to maintain current reliability levels. . In accordance with the OEB decision, HONI filed its draft rate order reflecting updated revenue requirements of $1,459 million for 2018, $1,498 million for 2019, $1,532 million for 2020, $1,578 million for 2021, and $1,624 million for 2022. In June 2019, the OEB approved the rate order confirming these updated revenue requirements.

In March 2018, the OEB issued a letter stating that the OEB expected HONI to file a joint distribution-transmission rate application for 2023-2027, including rates for Hydro One Remote Communities Inc. See “Business of Hydro One – Transmission Business Segment – Regulation – Recent Transmission Rate Applications – HONI” for more information.

In March 2019, HONI received the OEB’s decision on its 2018-2022 distribution rates application, which included reductions to Hydro One’s capital and operating costs. In accordance with the OEB decision, HONI filed its draft rate order reflecting updated revenue requirements. In June 2019, the OEB approved the rate order confirming the updated revenue requirements. At the end of March 2019, HONI filed a motion to

review and vary the OEB’s decision on HONI’s 2018-2022 distribution rates application as it relates to rates revenue requirement recovery of employer pension costs. Concurrently, an appeal to the Ontario Divisional Court was filed. The appeal was held in abeyance pending the outcome of the motion made before the OEB. In December 2019, the OEB affirmed its earlier decision with respect to recovery of the revenue requirement associated with pension costs. HONI has decided to discontinue its appeal of the OEB’s decision.

Hydro One Remote Communities Inc.

In August 2017, Hydro One Remote Communities Inc. filed an application seeking approval of the 2018-2022 revenue requirements and customer rates for the distribution and generation of electricity in the Hydro One Remote Communities service area. New rates were implemented on May 1, 2018.

In November 2018, Hydro One Remote Communities Inc. filed an application with the OEB seeking approval for increased base rates effective May 1, 2019. In February 2019, the OEB issued a draft decision approving the requested increase, which was later finalized in March 2019.

In November 2019, Hydro One Remote Communities Inc. filed an application and evidence in support of its proposed 2020 distribution rates. The application requested an increase to the base rates for the distribution and generation of electricity of 2.0% effective May 1, 2020. A decision from the OEB is pending.

Hydro One Remote Communities Inc.’s business is exempt from a number of sections of the Electricity Act which relate to the competitive market. For example, Hydro One Remote Communities Inc. continues to apply bundled rates to customers in remote communities. Hydro One Remote Communities Inc.’s business is operated on a break-even basis, without a return on equity included in rates. As a result, any net income or loss in the year related to the regulated operations of Hydro One Remote Communities Inc. is recorded in a regulatory variance account for inclusion in the calculation of future customer rates. See the Annual MD&A under the heading “Regulation – Electricity Rates Applications – Hydro One Remote Communities” for more information.

Conservation and Demand Management

Until March 2019, under the IESO’s 2015-2020 Conservation First Framework, distributors in Ontario offered CDM programs to customers to achieve specific energy savings targets. Distributors were responsible for developing and delivering CDM plans approved and funded by the IESO and reporting on their progress towards achieving projected energy savings targets.

In March 2019, the Province directed the IESO to cancel the 2015-2020 Conservation First Framework and assume accountability for centralized delivery of conservation programs under an interim framework. Hydro One continues to deliver CDM programs to those customers for whom CDM project applications had already been approved. The interim framework is in effect from April 1, 2019 to December 31, 2020 and offers energy-efficiency incentives and rebates to electricity customers. Under the interim framework, distributors,

including Hydro One, are allowed to offer local programs that do not overlap with the IESO’s program offerings.

Capital Expenditures

Hydro One’s asset sustainment activities are based on an assessment of asset condition. Distribution asset renewals are undertaken when assessments indicate there is a high risk of failure and where further maintenance activities are not appropriate. The Company expects capital expenditures for its distribution business in the near term to focus on new load connections, storm damage, wood pole replacement, and system capability reinforcement. In addition, the Company expects to continue to construct new distribution lines and stations in response to system growth forecasts, continued suburban community development, high load relief requirements and requirements to connect new sources of generation. The Company expects that it will spend in the range of approximately $632 million to $750 million per year over the next five years on capital expenditures relating to its distribution business. The projections are subject to approval by the OEB.

Hydro One is continuing to modernize its distribution system through the deployment of smart devices (including remotely controllable switches and breakers as well as faulted circuit indicators) as power system assets are renewed. Hydro One has implemented a Distribution Management System (“DMS”) at its Ontario Grid Control Centre. The DMS has enabled distribution components to be monitored and controlled, perform real-time analysis and determine, with greater precision, the location of equipment failures. Additional functionality is planned to allow field staff to view system conditions remotely in real-time. Smart metering data will also be used to deliver operational and asset management benefits such as better notification of outages and their scope, asset loading information and other data. See the Annual MD&A under the subheading “Capital Investments – Future Capital Investments” for more information on future capital expenditures.

Competitive Conditions

Hydro One’s distribution service area is described in its distribution licence issued by the OEB. Only one distributor is permitted to provide distribution services in a service territory, and distributors have exclusive rights to provide service to new customers located within their service territory. As a result, there is very little direct competition for distribution services in Ontario, except near the borders of adjoining service territories, where a distributor may apply to the OEB to claim the right to serve new customers or new loads not currently connected to its distribution grid.

To create more efficiency in the distribution sector, the Province continues to endorse the need for faster consolidation among local distribution companies in Ontario, resulting in competition for acquisition or merger opportunities. Potential acquirers may include strategic and financial buyers, in addition to other local distribution companies. Hydro One believes that it is well-positioned to continue to pursue consolidation opportunities within Ontario that are beneficial to all stakeholders. Consolidation continues within Ontario.

Other Segment

Hydro One’s other segment consists principally of its telecommunications business, which provides telecommunications support for the Company’s transmission and distribution businesses. The telecommunication business is carried out by its wholly-owned subsidiary HOTI. It also offers comprehensive communications and information technology services and solutions (for example, cloud services, managed services and security-based services) that extend beyond HOTI’s fibre optic network, in a competitive commercial market.

HOTI is not regulated by the OEB. However, HOTI is registered with the Canadian Radio-television and Telecommunications Commission as a non-dominant, facilities-based carrier, providing broadband telecommunications services in Ontario with connections to Montreal, Quebec; Buffalo, New York; and Detroit, Michigan.

The other segment also includes certain corporate activities including a deferred tax asset. The deferred tax asset arose on the transition from the provincial payments in lieu of tax regime to the federal tax regime in connection with the Company’s initial public offering and reflects the revaluation of the tax basis of Hydro One’s assets to fair market value.

The other segment represented approximately 7% of Hydro One’s total assets as at December 31, 2019, and accounted for approximately 1% of its total revenue, net of purchased power, in 2019 and 2018.

Indigenous Communities

Hydro One believes that building and maintaining respectful, positive and mutually beneficial relationships with Indigenous communities across the province is important to achieving the Company’s corporate objectives. Hydro One has established an Indigenous Relations Policy, demonstrating the Company’s desire to work proactively to build relationships with Indigenous communities based on understanding, respect and mutual trust. Hydro One is committed to working with Indigenous communities in a spirit of cooperation, partnership and shared responsibility. Hydro One’s equity partnerships with the Saugeen Ojibway Nation in respect of the Bruce-to-Milton transmission line and with the Six Nations of the Grand River Development Corporation and the Mississaugas of the Credit First Nation in respect of the Niagara Line demonstrate the Company’s commitment to these principles. In keeping with the Company’s Indigenous Relations Policy, Hydro One’s Indigenous Relations team provides guidance and advice to support the Company in developing and advancing positive relationships. Hydro One also has several programs related to Indigenous communities and their citizens. These include educational and training opportunities which provide opportunities for work terms, Indigenous procurement partnership agreements along with community investments, customer support and outreach. Together, HONI and Hydro One Remote Communities Inc. serve 104 First Nation communities.

The Company’s Health, Safety, Environment and Indigenous Peoples Committee of the Board is responsible for assisting the Board in discharging the Board’s oversight of responsibilities relating to effective occupational health and safety and environmental policies and practices at Hydro One, and its relationship with Indigenous communities.

Outsourced Services

Hydro One has outsourced certain non-core functions, including facilities management services with respect to its stations and other facilities, and certain back-office services such as information technology, payroll, supply chain and accounting services. The Company’s back-office services are provided by a third-party service provider under an agreement that expires on December 31, 2020 for finance, accounting and payroll services, on February 28, 2021 for information technology services, and on October 31, 2021 for supply chain services. The Company has decided not to renew its arrangement with the third-party service provider for settlements services, and has brought those services back into its operations commencing January 1, 2020. The Company has an option to renew the agreement in relation to the finance, accounting and payroll services for an additional term of one year. The Company’s facilities management services are provided by a third-party service provider under an agreement that expires on December 31, 2024, with an option for the Company to renew the agreement for an additional term of three years.

Employees

As at December 31, 2019, Hydro One had approximately 8,000 regular and non-regular employees province-wide comprised of a mix of skilled trades, engineering, professional, managerial and executive personnel. The average number of Hydro One employees in 2019 was approximately 8,800, consisting of approximately 5,800 regular employees and approximately 3,000 non-regular employees. Hydro One’s regular employees are supplemented primarily by accessing a large external labour force available through arrangements with the Company’s trade unions for contingent workers, sometimes referred to as “hiring halls”, and also by access to contract personnel. The hiring halls offer Hydro One the ability to access highly trained and appropriately skilled workers on a project-by-project basis. This arrangement provides the Company with more flexibility to address seasonal needs and unanticipated changes to its budgeted work programs. The Company also offers apprenticeship and technical training programs to ensure that future staffing needs will continue to be met.

On March 25, 2019, Hydro One Inc. and the Society of United Professionals (“Society”) announced the tentative settlement of a two-year collective agreement covering approximately 1,500 employees in critical engineering, supervisory and administrative roles. The agreement, covering the period from April 1, 2019 to March 31, 2021, was ratified by the Society on April 30, 2019. Collective agreements requiring renewal in 2020 include the Power Workers’ Union (“PWU”) and PWU customer service operations agreements.

See the Annual MD&A under the headings “Hydro One Work Force” and “Collective Agreements” for more information on employees.

Health, Safety and Environmental Management

Hydro One has an integrated Health, Safety and Environment Management System that includes key elements for the successful minimization of risk and continued performance improvements. Health, safety and environmental hazards and risks are identified and assessed, and controls are implemented to mitigate significant risks. The Company has policies in place regarding Health and Safety, Environment, Workplace Violence and Harassment and Public Safety.

HONI is a designated “Sustainable Electricity Company” by the Canadian Electricity Association. This designation demonstrates Hydro One’s commitment to responsible environmental, social and economic practices, and to the principles of sustainable development.

Given the nature of the work undertaken by Hydro One employees, health and safety remains one of the Company’s top priorities. Safety is one of Hydro One’s core values. The Company has developed and is continuing to develop a number of programs and initiatives for incident prevention and to minimize the risk of injury to its employees and the public associated with its facilities and operations.

Since 2004, Hydro One’s recordable incident rate, its key health and safety performance measure, has seen a reduction of approximately 89%. While we will continue to monitor and focus on reducing our recordable incident rate, our primary focus will be on the elimination of all serious injuries and fatalities as our key Health & Safety performance measure. We will also be raising the profile of our near miss accident reporting to ensure that we learn from and address the procedures, training and policies that lead to a safer workplace. All measures are monitored by management and by the Health, Safety, Environment and Indigenous Peoples Committee, a committee of the Board. Management compensation has been tied, in part, to meaningfully improving annual health and safety performance targets. In the event of a fatality and subject to a system investigation, this component of management compensation would not be paid. A program allowing for an effective early and safe return to work has allowed the Company to ensure that, when injuries occur, employees recover and return to the workplace as soon as possible.

Hydro One continues with its “Journey to Zero” safety initiative that began in 2009. This initiative compares Hydro One to other companies to identify performance gaps. Safety perception assessments were completed in 2009, 2013, 2015, 2017 and 2019. The assessment identified opportunities for improvement and a cross-functional team from across the Company will use this, and other inputs, to recommend activities that will make a significant difference to safety in the workplace.

Environmental Regulation

Hydro One is subject to extensive federal, provincial and municipal regulation relating to the protection of the environment that governs, among other things, environmental assessments, discharges to water and land and the generation, storage, transportation, disposal and release of various hazardous substances. Estimated environmental liabilities are reviewed annually or more frequently if significant changes in regulation or other relevant factors occur. Estimated changes are accounted for prospectively.

Permits and Approvals

The Company is required to obtain and maintain specified permits and approvals from federal, provincial and municipal authorities relating to the design, construction and operation of new and upgraded transmission and distribution facilities. Examples include environmental assessment approvals, permits for facilities to be located in parks or other regulated areas, water crossing permits, and approvals to discharge to air and water. Some projects may require environmental approvals from the federal government. Interconnections with neighbouring utilities in other provinces and states also require federal approval and will be subject to federal regulatory review.

In general, larger projects are subject to an individual environmental assessment process, pursuant to the Environmental Assessment Act. The majority of approvals fall under a class environmental assessment process which provides for more streamlined approvals. The scope, timing and cost of environmental assessments are dependent on the scale and type of project, the location (urban versus rural), the environmental sensitivity of affected lands and the significance of potential environmental effects.

Regulation of Releases

Federal, provincial and municipal environmental legislation regulates the release of specific substances into the environment through the prohibition of discharges that will or may have an adverse effect on the environment, which can include liquids, gasses and noise. Releases occur in the course of the Company’s normal operations. Accordingly, Hydro One has spill, leak prevention and leak mitigation programs involving the testing, replacement, repair and installation of containment systems including re-gasketting of transformers and sulphur-hexafluoride-filled equipment. In addition, the Company has an emergency response capability which the Company believes is sufficient to minimize the environmental impact of spills and to comply with its legal obligations.

Hazardous Substances

Hydro One manages a number of hazardous substances, such as PCBs, herbicides, and wood preservatives. In addition, some facilities have substances present which are designated for special treatment under occupational health and safety legislation, such as asbestos, lead and mercury. The Company has environmental management programs in place to deal with PCBs, herbicides, asbestos, and other hazardous substances.

Land Assessment and Remediation

Hydro One has a proactive land assessment and remediation program in place to identify and, where necessary, remediate historical contamination that has resulted from past operational practices and uses of certain long-lasting chemicals at the Company’s facilities. These programs involve the systematic identification of contamination at or from these facilities and, where necessary, the development of remediation plans for the Company’s properties and affected adjacent private properties. As at December 31, 2019, future expenditures related to Hydro One’s land assessment and remediation program were estimated at approximately $51 million. These expenditures are expected to be spent over the period ending 2044. Additional acquisitions could add to land assessment and remediation expenditures. The expenditures on this program for 2019 were approximately $8 million. These costs are expected to be recovered in the Company’s transmission and distribution rates.

Insurance

Hydro One maintains insurance coverage, including liability, all risk property, boiler and machinery and directors’ and officers’ insurance. The Company also maintains other insurance coverage that is required by law, covering risks such as automobile liability, pesticide liability and aircraft liability. The Company does not have insurance for damage to its transmission and distribution wires, poles or towers located outside transmission and distribution stations, including damage caused by severe weather, other natural disasters or catastrophic events or for environmental remediation costs. The OEB has generally permitted the recovery of costs associated with extreme weather events.

Ombudsman

The Electricity Act requires that the Company have an ombudsman to act as a liaison with customers and to establish procedures for the ombudsman to inquire into and report to the Board on matters raised with the ombudsman by or on behalf of customers. These procedures are set out in a written mandate and terms of reference.

The role of the ombudsman is to facilitate resolution of complaints by customers of the Company that remain unresolved after having been processed through the Company’s complaints handling process. The ombudsman is an impartial and independent investigator, who makes recommendations to facilitate the resolution of both individual and systemic issues with a view to achieving a resolution that is fair to both

the customer and the Company. The main purposes of the ombudsman are to address procedural and substantive unfairness, handle unresolved complaints, conduct systemic reviews that will lead to improvements in programs and systems, support the Company in holding its employees accountable for carrying out the Company’s directives and their responsibilities, and support the Board in its mandate to govern in a just, fair, and equitable manner. The ombudsman is mandated to work with the OEB to maintain integrated procedures for liaising with the Company and inquiring into matters raised by customers with the ombudsman. The ombudsman is an office of last resort within the Company.

Dividend Policy

The Board has established a dividend policy pursuant to which Hydro One Limited expects to pay an annualised dividend amount on its common shares, based on a target payout ratio of 70% to 80% of net income. The amount and timing of any dividends payable by Hydro One Limited will be at the discretion of the Board and will be established on the basis of Hydro One’s results of operations, maintenance of its deemed regulatory capital structure, financial condition, cash requirements, the satisfaction of solvency tests imposed by corporate laws for the declaration and payment of dividends and other factors that the Board may consider relevant.

The preferred shares of Hydro One Limited are entitled to a preference over the common shares with respect to the payment of dividends. Other than the foregoing, there is currently no restriction that would prevent the company from paying dividends at current levels.

For more information on dividends, see the notes to the audited consolidated financial statements of Hydro One Limited as at and for the years ended December 31, 2019 and 2018.

Dividend Reinvestment Plan

In February 2016, the Board approved the creation of a dividend reinvestment plan (the “Dividend Reinvestment Plan”) which is currently in place. The Dividend Reinvestment Plan enables eligible shareholders to have their regular quarterly cash dividends automatically reinvested in additional Hydro One common shares acquired on the open market.

DESCRIPTION OF CAPITAL STRUCTURE

The following description may not be complete and is subject to, and qualified in its entirety by reference to, the terms and provisions of Hydro One Limited’s articles, as they may be amended from time to time.

Common Shares

Holders of common shares are entitled to receive notice of and to attend all meetings of shareholders, except meetings at which only the holders of another class or series of shares are entitled to vote separately as a class or series, and holders of common shares are entitled to one vote per share at all such meetings of shareholders. Hydro One Limited’s common shares are not redeemable or retractable. Subject to the rights, privileges, restrictions and conditions attaching to any other class or series of shares, including the Series 1 preferred shares and Series 2 preferred shares, holders of common shares are entitled to receive dividends if, as, and when declared by the Board. Subject to the rights, privileges, restrictions and conditions attaching to any other class or series of shares, including the Series 1 preferred shares and Series 2 preferred shares, holders of common shares are also entitled to receive the remaining assets of Hydro One Limited upon its liquidation, dissolution or winding-up or other distribution of Hydro One Limited’s assets for the purposes of winding-up its affairs.

The Voting Securities of Hydro One Limited, which include the common shares, are subject to share ownership restrictions under the Electricity Act and certain other provisions contained in the articles of Hydro

Preferred Shares

Hydro One Limited may from time to time issue preferred shares in one or more series. Prior to issuing shares in a series, the Board is required to fix the number of shares in the series and determine the designation, rights, privileges, restrictions and conditions attaching to that series of preferred shares.

Subject to the OBCA, holders of Hydro One Limited’s preferred shares or a series thereof are not entitled to receive notice of, to attend or to vote at any meeting of the shareholders of Hydro One Limited except that votes may be granted to a series of preferred shares when dividends have not been paid on any one or more series as determined by the applicable series provisions. Each series of preferred shares ranks on parity with every other series of preferred shares with respect to dividends and the distribution of assets and return of capital in the event of the liquidation, dissolution or winding up of Hydro One Limited. The preferred shares are entitled to a preference over the common shares and any other shares ranking junior to the preferred shares with respect to payment of dividends and the distribution of assets and return of capital in the event of the liquidation, dissolution or winding up of Hydro One Limited.

For the period commencing from October 31, 2015, and ending on and including November 19, 2020, the holders of Series 1 preferred shares will be entitled to receive fixed cumulative preferential dividends of $1.0625 per share per year, if and when declared by the Board, payable quarterly on the 20^th^ day of November, February, May and August in each year.

The holders of Series 2 preferred shares will be entitled to receive quarterly floating rate cumulative dividends, if and when declared by the Board, at a rate equal to the sum of the then three-month Government of Canada treasury bill rate and 3.53% as reset quarterly. The Series 2 preferred shares will be redeemable by Hydro One Limited at a redemption price equal to $25.00 for each Series 2 preferred share redeemed if redeemed on November 20, 2025, or on November 20 every fifth year thereafter or $25.50 for each Series 2 preferred share redeemed if redeemed on any other date after November 20, 2020, in each case plus any accrued or

In the event of the liquidation, dissolution or winding-up of Hydro One Limited, or any other distribution of assets of Hydro One Limited for the purpose of winding-up its affairs, the holders of Series 1 preferred shares and Series 2 preferred shares will be entitled to receive $25.00 for each Series 1 preferred share and each Series 2 preferred share held by them, plus any unpaid dividends, before any amounts are paid or any assets of Hydro One Limited are distributed to holders of common shares and any shares ranking junior to the Series 1 preferred shares and Series 2 preferred shares. After payment of those amounts, the holders of Series 1 preferred shares and Series 2 preferred shares will not be entitled to share in any further distribution of the property or assets of Hydro One Limited.

Except as required by the OBCA, neither the holders of Series 1 preferred shares nor the holders of Series 2 preferred shares shall be entitled to receive notice of, or to attend meetings of shareholders of Hydro One Limited and shall not be entitled to vote at any such meeting, unless Hydro One Limited fails for eight quarters, whether or not consecutive, to pay in full the dividends payable on the Series 1 preferred shares or Series 2 preferred shares, as applicable, whereupon the holders of Series 1 preferred shares and Series 2 preferred shares, as applicable, shall become entitled to receive notice of and attend all meetings of shareholders, except class meetings of any other class of shares, and shall have one vote for each Series 1 preferred share or Series 2 preferred share held at such meetings, as applicable.

The Governance Agreement and the Registration Rights Agreement were entered into in connection with the completion of the initial public offering of Hydro One Limited in November 2015 and the Letter Agreement was entered into in connection with the retirement of the CEO and replacement of the Board in July 2018. The material terms of each are summarized below. A copy of each of the Governance Agreement, the Registration Rights Agreement and the Letter Agreement has been filed on SEDAR and is available under Hydro One Limited’s profile at www.sedar.com. The discussion in this annual information form concerning the Governance Agreement, the Registration Rights Agreement and the Letter Agreement is not complete, and is qualified in its entirety to the text of the Governance Agreement, the Registration Rights

Agreement and the Letter Agreement, each of which should be referred to. Not all of the terms of the Governance Agreement, the Registration Rights Agreement and the Letter Agreement are described in this annual information form.

Governance Agreement

Governance Matters

The Governance Agreement specifically addresses the following governance matters:

•	The governance principles under which Hydro One Limited and its subsidiaries will be managed and operated.
•	The nomination of directors, which includes: (i) the requirement for a fully independent board of directors (other than the CEO), and (ii) the maximum number of directors that may be nominated by the Province.
---	---
•	The election and replacement of directors.
---	---
•	Approvals requiring a special resolution of the directors.
---	---

Governance Principles

The Governance Agreement provides that the business and affairs of Hydro One Limited will be managed and operated in accordance with certain governance principles.

The governance principles provide that:

•	Hydro One Limited will maintain corporate governance policies, procedures and practices consistent with the best practices of leading Canadian publicly listed companies, having regard to Hydro One Limited’s ownership structure and the Governance Agreement.
•	The board of directors of Hydro One Limited is responsible for the management of the business and affairs of Hydro One Limited.
---	---
•	With respect to its ownership interest in Hydro One Limited, the Province will engage in the business and affairs of Hydro One Limited as an investor and not a manager, and the Province intends to achieve its policy objectives through legislation and regulation, as it would with respect to any other utility operating in Ontario.
---	---

Nomination of Directors

The Governance Agreement establishes qualification standards for director nominees, provides for the number of directors that may be nominated and establishes a process for confirming nominees. The Governance Agreement recognizes that the Board is to be a fully independent board (independent of both Hydro One and the Province), except the CEO, as described under the subheading “Independence” below.

Director Qualification Standards

Under the Governance Agreement, the Province and the Governance Committee (formerly the Nominating, Corporate Governance, Public Policy & Regulatory Committee) have agreed to nominate as directors qualified individuals of high quality and integrity who have the experience, expertise and leadership appropriate to manage a business of the complexity, size and scale of the business of Hydro One Limited, on a basis consistent with the highest standards for directors of Canada’s leading public companies.

In addition, a majority of the directors must be resident Canadians (as defined in the OBCA).

Independence

Each director nominee must, among other things:

•	be independent of Hydro One Limited (other than the CEO) within the meaning of Ontario securities laws governing the disclosure of corporate governance practices;
•	be independent of the Province (other than the CEO). A director will be independent of the Province if he or she would be independent of Hydro One Limited within the meaning of Ontario securities laws governing the disclosure of corporate governance practices if the Province and each Specified Provincial Entity were treated as Hydro One Limited’s parent under that definition. In addition, he or she may not be an employee or official of the Province or any Specified Provincial Entity, either: (i) currently or (ii) within the last three years; and
---	---
•	meet the requirements of applicable securities and other laws and any exchange on which the voting securities are listed.
---	---

A “Specified Provincial Entity” means (1)(a) the Ontario Financing Authority, (b) the IESO, (c) Ontario Power Generation Inc., (d) the Electrical Safety Authority, (e) Ontario Electricity Financial Corporation, (f) Infrastructure Ontario, or (g) a subsidiary of, or a person controlled by, any organization listed in (a) to (f); and (2) the OEB.

Number of Directors

Under the articles of Hydro One Limited and pursuant to the terms of the Governance Agreement, the Board will consist of no fewer than 10 and no more than 15 directors, with the initial Board consisting of 15 directors until the first annual meeting of shareholders following the completion of the initial public offering of Hydro One Limited.

Board Nominees

The nominees to be proposed for election to the Board by Hydro One Limited at annual meetings of shareholders will be determined as follows:

•	The CEO will be nominated.
•	The Province will be entitled to nominate that number of nominees equal to 40% of the number of directors to be elected (rounded to the nearest whole number), subject to certain exceptions.
---	---
•	The Governance Committee will nominate the remaining directors.
---	---

Board Nomination Process

Under the Governance Agreement, the Province and representatives of the Governance Committee are to meet after each annual meeting of shareholders to discuss expected upcoming departures from the Board (whether due to resignation, retirement or otherwise) and the impact such departures will have on the Board, having regard to continued compliance with the Governance Agreement and the ability of the Board to satisfy the Board’s skills matrix, diversity policy and other governance standards. Under the Governance Agreement, at this meeting the Governance Committee is to make recommendations to the Province respecting potential candidates for director, including potential candidates for nomination by the Province. The Province has no obligation to nominate any of the individuals recommended as one of its director nominees.

Not later than 60 days prior to the date by which proxy solicitation materials must be mailed for Hydro One’s annual meeting of shareholders, each of the Province and the Governance Committee will notify the other of its proposed director nominees. If a proposed nominee is not already a director of Hydro One, or is then a director but whose circumstances have materially changed in a way that would affect whether she or he would continue to meet the director qualification standards under the Governance Agreement, then the Province or the committee, as the case may be, will have 10 business days to confirm that nominee or reject that nominee on the basis that the nominee does not meet those director qualification standards.

If a director nominee of the Province or the Governance Committee is rejected, then the Province or the committee will be entitled to nominate additional candidates until a nominee is confirmed by the other. If no replacement nominee is confirmed for a director who was expected to depart from the board and that director does not resign, that director shall be re-nominated. The Province and the committee will use commercially reasonable efforts to confirm director nominees prior to the date by which proxy solicitation

materials must be mailed for the annual meeting of shareholders.

Election and Replacement of Directors

The Governance Agreement provides for how:

•	the Province will vote with respect to director nominees, including its nominees and those of the Governance Committee,
•	the Province may vote at contested elections,
---	---
•	the Province may seek to replace the Board by withholding votes or voting for removal, and
---	---
•	Board vacancies will be filled.
---	---

Voting on Director Elections

At any meeting of shareholders to elect directors, the Province is required to vote in favour of the nominees selected by the Province and the Governance Committee in accordance with the board nomination process set out in the Governance Agreement, except in the case of contested director elections or where the Province seeks to replace the Board in accordance with the Governance Agreement.

Contested Elections

At any meeting of shareholders to elect directors of Hydro One Limited at which there are more nominees for directors than there are directors to be elected, the Province may vote its Voting Securities in its sole discretion (including to vote in favour of other candidates instead of the Province’s nominees), except that the Province will vote in favour of the election of the CEO as a director.

Right to Withhold Votes

The Province is required under the Governance Agreement to vote in favour of all director nominees of Hydro One Limited, subject to the Province’s overriding right to withhold from voting in favour of all director nominees and its right to seek to remove and replace the entire Board, including in each case its own director nominees but excluding the CEO and, at the Province’s discretion, the Chair. Depending on the number of withheld votes a director nominee receives at a meeting of shareholders at which directors are to be elected, that director nominee may be required to tender his or her resignation to the Board in accordance with Hydro One Limited’s majority voting policy.

Province’s Right to Replace the Board

The Province may at any time notify Hydro One Limited that it intends to request that Hydro One Limited hold a meeting of shareholders for the purposes removing all of the directors in office, including those

nominated by the Province, with the exception of the CEO and, at the sole discretion of the Province, the Chair (a “Removal Notice”). If the Province gives Hydro One a Removal Notice, then the Chair shall coordinate the establishment of an ad hoc nominating committee comprising one representative of each of the five largest beneficial owners of Voting Securities known to the Company (or if at least three such owners are not willing to provide a representative, then the individuals the Province proposes to nominate as replacement directors). The Province and the ad hoc nominating committee will identify and confirm replacement directors to be nominated at the shareholders’ meeting pursuant in accordance with the process set out in the Governance Agreement. Each replacement director nominee must meet the same qualification and independence standards under the Governance Agreement as for any director nominee. Hydro One Limited will call the shareholders’ meeting once the replacement director nominees are confirmed pursuant to this process, and will hold the shareholders’ meeting within 60 days of this confirmation. At the shareholders’ meeting, the Province will vote in favour of removing the current directors with the exception of the CEO and, at the Province’s discretion, the Chair, and will vote in favour of the new independent director nominees.

Board Approvals Requiring a Special Resolution of the Directors

The Governance Agreement provides that certain actions require approval by a resolution of the Board passed by at least two-thirds of the votes cast at a meeting of the directors, or consented to in writing by all of the directors (a “Special Board Resolution”). Matters requiring approval by a Special Board Resolution include:

•	the appointment and annual confirmation of the Chair,
•	the appointment and annual confirmation of the CEO, and
---	---
•	changes to certain specified governance standards specified in the Governance Agreement to be “Hydro One’s governance standards”.
---	---

The governance standards subject to this special approval requirement include the Board’s skills matrix, the Ombudsman’s Mandate, the Diversity Policy and the Majority Voting Policy, the Corporate Governance Guidelines, the mandates of the Board and its committees, position descriptions for the CEO, the Chair, the directors and committee chairs, and the Stakeholder Engagement Policy.

Other Matters

In addition to the governance matters noted above, the Governance Agreement also addresses the following matters:

•	Restrictions on the right of the Province to initiate fundamental changes.
•	Pre-emptive rights provided to the Province with respect to future issuances of Voting Securities by Hydro One Limited.
---	---
•	Acquisition limits with respect to the Province’s acquisition of outstanding Voting Securities.
---	---

Restrictions on Province’s Right to Initiate Fundamental Changes

The Province has agreed not to initiate a fundamental change to Hydro One Limited (as defined in Part XIV of the OBCA), including not to initiate any arrangement or amalgamation involving Hydro One Limited or any amendment to the articles of Hydro One Limited. The Province may, however, vote its Voting Securities as it sees fit in the event any fundamental change is initiated by Hydro One Limited or another shareholder of Hydro One Limited.

Pre-emptive Rights

Hydro One Limited has granted to the Province a pre-emptive right to acquire additional Voting Securities as part of future offerings by Hydro One Limited of Voting Securities. If Hydro One Limited proposes to issue Voting Securities in the future, whether pursuant to a public offering or a private placement, Hydro One Limited must notify the Province of the proposal and provide information in accordance with the provisions of the Governance Agreement at least 30 days in advance and must offer the Province the right to purchase up to 45% of the Voting Securities being offered. Any Voting Securities not purchased by the Province pursuant to the offer may be purchased by any other person pursuant to the proposed offering.

The pre-emptive right also applies with respect to any proposed issuance by Hydro One Limited of securities convertible into or exchangeable for Voting Securities except securities convertible into or exchangeable for Voting Securities: (i) pursuant to certain employee or director compensation plans; (ii) pursuant to any dividend re-investment arrangement of the Company that is consistent with dividend reinvestment arrangements of other publicly traded utilities in Canada (including as to discount rates) and that does not include a cash purchase option; (iii) pursuant to a rights offering that is open to all shareholders of Hydro One Limited; or (iv) pursuant to any business combination, take-over bid, arrangement, asset purchase transaction or other acquisition of assets or securities of a third-party.

45% Acquisition Limit

The Province has agreed in the Governance Agreement, subject to certain exceptions, not to acquire previously issued Voting Securities if, after that acquisition, the Province would own more than 45% of any class or series of Voting Securities. This restriction does not limit the Province from acquiring Voting Securities on an issuance by Hydro One Limited, including pursuant to the exercise by the Province of its pre-emptive right. See “Agreements with Principal Shareholder – Governance Agreement – Other Matters – Pre-emptive Rights” above.

Registration Rights Agreement

Demand Registration

Pursuant to the Registration Rights Agreement, Hydro One Limited has granted the Province certain demand registration rights providing that, from time to time while the Province is a “control person” of Hydro One Limited within the meaning of applicable Canadian securities laws, the Province can require Hydro One Limited to file, at the expense of the Province (except for internal expenses of Hydro One Limited or other expenses that Hydro One Limited would have incurred in the absence of such a request), and subject to certain exceptions, one or more prospectuses and take other procedural steps as may be reasonably necessary to facilitate a secondary offering in Canada of all or any portion of the common shares or preferred shares (“shares”) held by the Province.

“Piggy-Back” Registration

If Hydro One Limited proposes to undertake a Canadian public offering by prospectus, the Province is entitled, while it is a “control person” of Hydro One Limited within the meaning of applicable Canadian securities laws, to include shares owned by it as part of that offering, provided that the underwriters may reduce the number of shares proposed to be sold if in their reasonable judgment all of the shares proposed to be offered by Hydro One Limited and the Province may not be sold in an orderly manner within a price range reasonably acceptable to Hydro One Limited. In that case, the shares to be sold will be allocated pro rata between Hydro One Limited and the Province based on their relative proportionate number of shares requested to be included in the offering. Hydro One Limited and the Province will share the expenses of the offering (except for internal expenses of Hydro One Limited) in proportion to the gross proceeds they each receive from the offering.

Private Placements

Hydro One Limited has also agreed to use commercially reasonable efforts to assist, at the Province’s expense, the Province in any sale by it of shares of Hydro One Limited pursuant to an exemption from the prospectus requirements, in the preparation of an offering memorandum and other documentation and by facilitating due diligence by the prospective buyer.

Customary Agreements

Hydro One Limited and the Province have also agreed to enter into customary agreements, including “lock-up” agreements, on customary market terms in connection with such transactions. Hydro One Limited also agreed to certain indemnification and contribution covenants in favour of the Province and any underwriters involved in such transactions.

Letter Agreement

The Letter Agreement set out the agreement between Hydro One Limited and the Province with respect to the orderly replacement of the Company’s Board and the retirement of Mr. Mayo Schmidt as the CEO effective July 11, 2018.

In addition to certain provisions dealing specifically with the 2018 replacement of the Company’s Board and the retirement of Mr. Schmidt as the CEO in July 2018, other key highlights of the Letter Agreement include:

•	Hydro One Limited agreed to consult with the Province in respect of future matters of executive compensation; and
•	The Province ratified and reaffirmed its obligations under the Governance Agreement and agreed that except as set out in the Letter Agreement, the Letter Agreement did not amend or modify the Governance Agreement and the Governance Agreement remained in full force and effect.
---	---

INTEREST OF MANAGEMENT AND OTHERS IN MATERIAL TRANSACTIONS

Other than as noted below and elsewhere in this annual information form, there are no material interests, direct or indirect, of any director or executive officer of the Company, any shareholder that beneficially owns, or controls or directs (directly or indirectly), more than 10% of any class or series of Hydro One Limited’s outstanding voting securities, or any associate or affiliate of any of the foregoing persons, in any transaction within the three most recently completed financial years or during the current financial year, up to the date of this annual information form, that has materially affected or is reasonably expected to materially affect the Company.

Relationships with the Province and Other Parties

Overview

The Province is Hydro One Limited’s principal shareholder. The OEB is the principal regulator of Ontario’s electricity industry. The Province appoints the board members of the OEB and fills any vacancies on the OEB. The OEB is obligated to implement approved directives of the Province concerning general policy and objectives to be pursued by the OEB and other directives aimed at addressing existing or potential abuses of market power by industry participants. The IESO, among other matters, directs the operation of the Ontario power system by balancing supply and demand of electricity and directing electricity flow and assumed the responsibility for forecasting supply and demand of electricity over the medium and long term to meet the needs of the province. The board of directors of the IESO, other than its CEO, is appointed by the Province in accordance with the regulations in effect from time to time under the Electricity Act.

In connection with the initial public offering of Hydro One Limited, the Company entered into the Governance

Agreement and the Registration Rights Agreement with the Province. Following the election of a new government in Ontario in June 2018, the Company and the Province entered into the Letter Agreement. See “Agreements with Principal Shareholder”.

Transfer Orders

The transfer orders pursuant to which Hydro One Inc. acquired Ontario Hydro’s electricity transmission, distribution and energy services businesses as of April 1, 1999, did not transfer certain assets, rights, liabilities or obligations where the transfer would constitute a breach of the terms of any such asset, right, liability or obligation or a breach of any law or order (the “trust assets”). The transfer orders did not transfer title to assets located on Reserves, which assets are held by OEFC. See the Annual MD&A under the subheading “Risk Management and Risk Factors – Risks Relating to Hydro One’s Business – Risk from Transfer of Assets Located on Reserves” for more information.

Until it has obtained all consents necessary to complete the transfer of title to these assets to Hydro One, Hydro One is obligated under the transfer orders to manage both the trust assets and the assets otherwise retained by OEFC that relate to Hydro One’s businesses. Hydro One has entered into an agreement with OEFC under which it is obligated, in managing these assets, to take instructions from OEFC if Hydro One’s actions could have a material adverse effect on OEFC. OEFC has retained the right to take control of and manage the assets, although it must notify and consult with Hydro One before doing so and must exercise its powers relating to the assets in a manner that will facilitate the operation of Hydro One’s businesses. The consent of OEFC is also required prior to any disposition of these assets.

The Province also transferred officers, employees, assets, liabilities, rights and obligations of Ontario Hydro in a similar manner to its other successor transferees. These transfer orders include a dispute resolution mechanism to resolve any disagreement among the various transferees with respect to the transfer of specific assets, liabilities, rights or obligations.

The transfer orders do not contain any representations or warranties from the Province or OEFC with respect to the transferred officers, employees, assets, liabilities, rights and obligations. Furthermore, under the Electricity Act, OEFC was released from liability in respect of all assets and liabilities transferred by the transfer orders, except for liability under Hydro One’s indemnity from OEFC. The parties, with the consent of the Minister of Finance, agreed to terminate such indemnity effective October 31, 2015. By the terms of the transfer orders, each transferee indemnifies OEFC with respect to any assets and liabilities related to that transferee’s business not effectively transferred, and is obligated to take all reasonable measures to complete the transfers where the transfers were not effective.

Hydro One has indemnified OEFC in respect of the damages, losses, obligations, liabilities, claims, encumbrances, penalties, interest, taxes, deficiencies, costs and expenses arising from matters relating to the Company’s business and any failure by Hydro One to comply with its obligations to OEFC under agreements dated as of April 1, 1999. These obligations include obligations to employ the employees transferred to Hydro One under the transfer orders, make and remit employee source deductions (including tax withholding

amounts, and employer contributions), manage the real and personal properties which OEFC continues to hold in trust or otherwise and take any necessary action to transfer all of these properties to the Company, to pay realty taxes and other costs, provide access to books and records and to assume other responsibilities in respect of the assets held by OEFC in trust for the Company.

Departure Taxes

By virtue of being wholly owned by the Province, Hydro One was exempt from tax under the federal Income Tax Act and the Province’s Taxation Act (the “Tax Acts”). However, under the Electricity Act, Hydro One was required to make payments in lieu of tax to OEFC. The payments in lieu of tax were, in general, equivalent to the amount of tax that Hydro One would otherwise be liable to pay under the Tax Acts if it was not exempt from taxes under those statutes.

In connection with the initial public offering of Hydro One Limited, Hydro One’s exemption from tax under the Tax Acts ceased to apply. Under the Tax Acts, Hydro One was deemed to have disposed of its assets immediately before it lost its tax exempt status resulting in Hydro One making payments in lieu of tax under the Electricity Act totalling approximately $2.6 billion in respect thereof, calculated by reference to the federal Income Tax Act (“departure tax”).

Hydro One Inc. also paid OEFC approximately $0.3 billion in additional payments in lieu of tax in connection with the period prior to the initial public offering.

For a discussion of the departure tax and the related financial implications on the Company, see “Business of Hydro One – Transmission Business Segment – Regulation – Recent Transmission Rate Applications” as well as the Annual MD&A under the heading “Risk Management and Risk Factors – Risks Relating to Hydro One’s Business – Risks Relating to Regulatory Treatment of Deferred Tax Asset”.

MATERIAL CONTRACTS

The following are the only material contracts, other than those contracts entered into in the ordinary course of business, which Hydro One Limited has entered into since the beginning of the last financial year, or entered into prior to such date but which contract is still in effect:

(a)	a termination of merger agreement dated January 23, 2019, between Hydro One Limited, Olympus Holding Corp., Olympus Corp. and Avista Corporation (the “Termination Agreement”), which terminated the Merger Agreement. The Termination Agreement provided that Hydro One Limited pay Avista Corporation a U.S. $103 million termination fee, as required by the Merger Agreement;
(b)	the Governance Agreement, described under “Agreements with Principal Shareholder”;
---	---
(c)	the Registration Rights Agreement, described under “Agreements with Principal Shareholder”; and
---	---

(d)	the Letter Agreement, described under “Agreements with Principal Shareholder”.

Copies of the foregoing material agreements have been filed with the Canadian securities regulatory authorities and are available on SEDAR at www.sedar.com. As of the date of this annual information form, HOHL has not issued any debt securities pursuant to the HOHL Indenture and accordingly the HOHL Indenture is not considered a material agreement. If and when such debt securities are issued pursuant to the HOHL Indenture, such agreement may be considered a material agreement.

LEGAL PROCEEDINGS AND REGULATORY ACTIONS

The Company is from time to time involved in legal proceedings of a nature considered normal to its business. Except as disclosed below, Hydro One believes that none of the litigation in which it is currently involved, or has been involved since the beginning of the most recently completed financial year, individually or in the aggregate, is material to its consolidated financial condition or results of operations. The Company is not subject to any material regulatory actions.

Hydro One Inc., HONI, Hydro One Remote Communities Inc., and Norfolk Power were defendants in a class action suit commenced on September 9, 2015 in which the representative plaintiff was seeking up to $125 million in damages related to allegations of improper billing practices. The plaintiff’s motion for certification was dismissed by the Superior Court of Ontario in November 2017. The plaintiff’s application for leave to appeal the lower court’s refusal to certify the lawsuit as a class action was denied by the Ontario Court of Appeal in March 2019, which means that the lawsuit has effectively ended.

In connection with the reorganization of Ontario Hydro, Hydro One Inc. succeeded Ontario Hydro as a party to various pending legal proceedings relating to the businesses, assets, real estate and employees transferred to it. Hydro One Inc. also assumed responsibility for future claims relating to the businesses, assets, real estate and employees acquired by Hydro One Inc. and arising out of events occurring prior to, as well as after, April 1, 1999. In addition to claims assumed by the Company, it is, from time to time, named as a defendant in legal actions arising in the normal course of business. There are currently no actions that are outstanding which are expected to have a material adverse effect on the Company.

There were four putative class action lawsuits filed by Avista Corporation shareholders in relation to the Merger. First, Fink v. Morris, et al. was filed in Washington state court and an amended complaint named as defendants Avista Corporation’s directors, Hydro One, Olympus Holding Corp., Olympus Corp., and Bank of America Merrill Lynch. The suit alleged that Avista Corporation’s directors breached their fiduciary duties in relation to the Merger, aided and abetted by Hydro One, Olympus Holding Corp., Olympus Corp. and Bank of America Merrill Lynch. Second, Jenß v. Avista Corp., et al., Samuel v. Avista Corp., et al., and Sharpenter v. Avista Corp., et al., were each filed in the US District Court for the Eastern District of Washington and named as defendants Avista Corporation and its directors; Sharpenter also named Hydro One, Olympus Holding Corp., and Olympus Corp. The lawsuits alleged that the preliminary proxy statement omitted material facts necessary to make the statements therein not false or misleading. All of these class action lawsuits have now been dismissed.

HYDRO ONE LIMITED

MANAGEMENT'S REPORT

The Consolidated Financial Statements, Management’s Discussion and Analysis (MD&A) and related financial information have been prepared by the management of Hydro One Limited (Hydro One or the Company). Management is responsible for the integrity, consistency and reliability of all such information presented. The Consolidated Financial Statements have been prepared in accordance with United States Generally Accepted Accounting Principles and applicable securities legislation. The MD&A has been prepared in accordance with National Instrument 51-102.

The preparation of the Consolidated Financial Statements and information in the MD&A involves the use of estimates and assumptions based on management’s judgment, particularly when transactions affecting the current accounting period cannot be finalized with certainty until future periods. Estimates and assumptions are based on historical experience, current conditions and various other assumptions believed to be reasonable in the circumstances, with critical analysis of the significant accounting policies followed by the Company as described in Note 2 to the Consolidated Financial Statements. The preparation of the Consolidated Financial Statements and the MD&A includes information regarding the estimated impact of future events and transactions. The MD&A also includes information regarding sources of liquidity and capital resources, operating trends, risks and uncertainties. Actual results in the future may differ materially from the present assessment of this information because future events and circumstances may not occur as expected.

Management is responsible for establishing and maintaining adequate disclosure controls and procedures and internal control over financial reporting as described in the annual MD&A. Management evaluated the effectiveness of the design and operation of disclosure controls and procedures and internal control over financial reporting based on the framework and criteria established in the Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that evaluation, management concluded that the Company’s internal control over financial reporting was effective at a reasonable level of assurance as of December 31, 2019. As required, the results of that evaluation were reported to the Audit Committee of the Hydro One Board of Directors and the external auditors.

The Consolidated Financial Statements have been audited by KPMG LLP, independent external auditors appointed by the shareholders of the Company. The external auditors’ responsibility is to express their opinion on whether the Consolidated Financial Statements are fairly presented in all material respects in accordance with United States Generally Accepted Accounting Principles. The Independent Auditors’ Report outlines the scope of their examination and their opinion.

The Hydro One Board of Directors, through its Audit Committee, is responsible for ensuring that management fulfils its responsibilities for financial reporting and internal control over reporting and disclosure. The Audit Committee of Hydro One met periodically with management, the internal auditors and the external auditors to satisfy itself that each group had properly discharged its respective responsibility and to review the Consolidated Financial Statements before recommending approval by the Board of Directors. The external auditors had direct and full access to the Audit Committee, with and without the presence of management, to discuss their audit findings.

On behalf of Hydro One’s management:

HYDRO ONE LIMITED

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors of Hydro One Limited

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Hydro One Limited (the Company) as of December 31, 2019 and 2018, the related consolidated statements of operations and comprehensive income (loss), changes in equity, and cash flows for each of the years in the two-year period ended December 31, 2019, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2019, in conformity with US generally accepted accounting principles.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the US federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Evaluation of regulatory assets and liabilities and the impact of rate regulation on the financial statements

As discussed in Notes 2 and 12 to the consolidated financial statements, the Company accounts for its regulated operations in accordance with Financial Accounting Standards Board Accounting Standard Codification Topic 980, Regulated Operations (ASC 980). Under ASC 980, the actions of the Company’s regulator may result in the recognition of revenue and costs in time periods that are different than non-rate-regulated enterprises. When this occurs, the Company records incurred and accrued costs that it has assessed are probable of recovery in future electricity rates as regulatory assets. Obligations imposed or probable to be imposed by the regulator to refund previously collected revenue or to spend revenue collected from customers on future costs are recorded as regulatory liabilities. Under ASC 980, the carrying amounts of property, plant and equipment are impacted by the regulator’s actions to the extent that incurred costs are allowed or disallowed to be recovered for rate-making purposes. As at December 31, 2019, the Company’s regulatory assets were $2,728 million and regulatory liabilities were $212 million.

We identified the evaluation of regulatory assets and liabilities and the impact of rate regulation as a critical audit matter. Accounting for regulated operations under ASC 980 affects multiple financial statement accounts and disclosures in the Company’s consolidated financial statements. Assessing the accounting for regulated operations requires significant knowledge thereof and auditor judgment due to interpretations of regulatory decisions and judgments involved in evaluating the Company’s assessment of the probability associated with recovery of regulatory assets and property, plant and equipment and disposition of regulatory liabilities.

The primary procedures we performed to address the critical audit matter included the following. We tested certain internal controls over the initial recognition of amounts as regulatory assets and liabilities and the monitoring and evaluation of regulatory developments that may affect the likelihood of recovering costs in future rates or obligations for disposition of regulatory liabilities. We evaluated the Company’s assessment of the probability of recovery of the carrying amount of regulatory assets and property, plant and equipment and the disposition of regulatory liabilities, through consideration of on-going regulatory proceedings and decisions, assessment of the Company’s interpretations of regulatory decisions and reading the opinion of the Company’s external legal

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For the years ended December 31, 2019 and 2018

1. DESCRIPTION OF THE BUSINESS

Hydro One Limited (Hydro One or the Company) was incorporated on August 31, 2015, under the Business Corporations Act (Ontario). On October 31, 2015, the Company acquired Hydro One Inc., a company previously wholly-owned by the Province of Ontario (Province). The acquisition of Hydro One Inc. by Hydro One was accounted for as a common control transaction and Hydro One is a continuation of business operations of Hydro One Inc. At December 31, 2019, the Province held approximately 47.3% (2018 - 47.4%) of the common shares of Hydro One. The principal businesses of Hydro One are the transmission and distribution of electricity to customers within Ontario.

Rate Setting

The Company's transmission business consists of the transmission system operated by Hydro One Inc.’s subsidiaries, Hydro One Networks Inc. (Hydro One Networks) and Hydro One Sault Ste. Marie LP (HOSSM), as well as an approximately 66% interest in B2M Limited Partnership (B2M LP), a limited partnership between Hydro One and the Saugeen Ojibway Nation (SON), and an approximately 75% interest in Niagara Reinforcement Limited Partnership (NRLP), a limited partnership between Hydro One and Six Nations of the Grand River Development Corporation and the Mississaugas of the Credit First Nation (collectively, the First Nations Partners). See Note 4 - Business Combinations and Note 34 - Subsequent Events for additional information. Hydro One’s distribution business consists of the distribution system operated by Hydro One Inc.'s subsidiaries, Hydro One Networks and Hydro One Remote Communities Inc. (Hydro One Remote Communities).

Transmission

On March 7, 2019, the Ontario Energy Board (OEB) issued a decision on its reconsideration of its decision and order on Hydro One Networks' 2017 and 2018 transmission rates revenue requirement dated September 28, 2017 (Original Decision) with respect to the rate-setting treatment of the benefits of the deferred tax asset resulting from the transition from the payments in lieu of tax regime under the Electricity Act, 1998 (Ontario) to tax payments under the federal and provincial tax regimes which occurred when Hydro One became a public company listed on the Toronto Stock Exchange. See Note 12 - Regulatory Assets and Liabilities for additional information. On October 26, 2018, Hydro One filed a one-year inflation-based application with the OEB for 2019 transmission revenue requirement. On April 25, 2019, the OEB issued its decision on Hydro One Networks’ 2019 transmission rate application, and set the revenue index at 1.4% on a final basis effective May 1, 2019.

In December 2015, the OEB approved B2M LP’s 2015-2019 rates revenue requirements of $39 million, $36 million, $37 million, $38 million and $37 million for the respective years. On November 23, 2018, B2M LP filed a revised 2019 revenue requirement with the OEB using the updated cost of capital parameters. On December 20, 2018, the OEB issued its decision approving the requested 2019 revenue requirement of $33 million, effective January 1, 2019.

HOSSM is under a 10-year deferred rebasing period for years 2017-2026, as approved in the OEB Mergers Acquisitions Amalgamations and Divestitures (MAAD) decision dated October 13, 2016. In July 2018, HOSSM filed a 2019 application for permission to include a revenue cap escalator index, which would allow for inflationary increases to its previously approved revenue requirement. On June 20, 2019, the OEB approved the revenue cap escalator index at 1.1% (net) which was applied to HOSSM's base revenue requirement for 2019, effective February 1, 2019, and also approved the 2019-2026 revenue cap framework.

On September 26, 2019, the OEB approved NRLP’s request to establish a deferral account to record NRLP’s 2019 revenue requirement prior to its inclusion in the Uniform Transmission Rates (UTRs).

Distribution

In March 2017, Hydro One Networks filed an application with the OEB for 2018-2022 distribution rates. On March 7, 2019, the OEB rendered its decision on the distribution rates application. In accordance with the OEB decision, the Company filed its draft rate order reflecting updated revenue requirements of $1,459 million for 2018, $1,498 million for 2019, $1,532 million for 2020, $1,578 million for 2021, and $1,624 million for 2022. On June 11, 2019, the OEB approved the rate order confirming these updated revenue requirements. See Note 12 - Regulatory Assets and Liabilities for additional information.

On March 26, 2019, the Company filed a motion to review and vary the OEB's decision with respect to recovery of pension costs. On December 19, 2019, the OEB affirmed its earlier decision with respect to recovery of the pension costs. See Note 12 - Regulatory Assets and Liabilities for additional information.

On November 5, 2018, Hydro One Remote Communities filed an application with the OEB seeking approval for increased base rates of 1.8% effective May 1, 2019. On March 28, 2019, the OEB issued a decision approving the requested increase.

2. SIGNIFICANT ACCOUNTING POLICIES

Basis of Consolidation and Presentation

These Consolidated Financial Statements (Consolidated Financial Statements) include the accounts of the Company and its subsidiaries. Inter-company transactions and balances have been eliminated.

HYDRO ONE LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

For the years ended December 31, 2019 and 2018

On March 25, 2019, the Company filed amended consolidated financial statements as at and for the year ended December 31, 2018 to reflect the impact of the March 7, 2019 decision issued by the OEB relating to the Deferred Tax Asset portion of the OEB's decision on Hydro One Networks' 2017 and 2018 transmission revenue requirement, for which the OEB previously granted a Motion to Review and Vary. The comparative information in these Consolidated Financial Statements reflects the amended consolidated financial statements as at and for the year ended December 31, 2018.

Basis of Accounting

These Consolidated Financial Statements are prepared and presented in accordance with United States (US) Generally Accepted Accounting Principles (GAAP) and in Canadian dollars.

Use of Management Estimates

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues, expenses, gains and losses during the reporting periods. Management evaluates these estimates on an ongoing basis based upon historical experience, current conditions, and assumptions believed to be reasonable at the time the assumptions are made, with any adjustments being recognized in results of operations in the period they arise. Significant estimates relate to regulatory assets and regulatory liabilities, environmental liabilities, pension benefits, post-retirement and post-employment benefits, asset retirement obligations, goodwill and asset impairments, contingencies, unbilled revenues, and deferred income tax assets and liabilities. Actual results may differ significantly from these estimates.

Regulatory Accounting

The OEB has the general power to include or exclude revenues, costs, gains or losses in the rates of a specific period, resulting in a change in the timing of accounting recognition from that which would have been applied in an unregulated company. Such change in timing involves the application of rate-regulated accounting, giving rise to the recognition of regulatory assets and liabilities. The Company’s regulatory assets represent amounts receivable from future customers and costs that have been deferred for accounting purposes because it is probable that they will be recovered in future rates. In addition, the Company has recorded regulatory liabilities that generally represent amounts that are refundable to future customers. The Company continually assesses the likelihood of recovery of each of its regulatory assets and continues to believe that it is probable that the OEB will include its regulatory assets and liabilities in setting future rates. If, at some future date, the Company judges that it is no longer probable that the OEB will include a regulatory asset or liability in setting future rates, the appropriate carrying amount would be reflected in results of operations prospectively from the date the Company’s assessment is made, unless the change meets the requirements for a subsequent event adjustment.

Cash and Cash Equivalents

Cash and cash equivalents include cash and short-term investments with an original maturity of three months or less.

Revenue Recognition

Nature of Revenues

Transmission revenues predominantly consist of transmission tariffs, which are collected through OEB-approved UTRs which are applied against the monthly peak demand for electricity across Hydro One's high-voltage network. OEB-approved UTRs are based on an approved revenue requirement that includes a rate of return. The transmission tariffs are designed to recover revenues necessary to support the Company's transmission system with sufficient capacity to accommodate the maximum expected demand which is influenced by weather and economic conditions. Transmission revenues are recognized as electricity is transmitted and delivered to customers.

Distribution revenues attributable to the delivery of electricity are based on OEB-approved distribution rates and are recognized on an accrual basis and include billed and unbilled revenues. Billed revenues are based on electricity delivered as measured from customer meters. At the end of each month, electricity delivered to customers since the date of the last billed meter reading is estimated, and the corresponding unbilled revenue is recorded. The unbilled revenue estimate is affected by energy consumption, weather, and changes in the composition of customer classes.

Revenues also include amounts related to sales of other services and equipment. Such revenue is recognized as services are rendered or as equipment is delivered. Revenues are recorded net of indirect taxes.

Accounts Receivable and Allowance for Doubtful Accounts

The Company early-adopted Accounting Standard Update (ASU) 2016-13 Financial Instruments - Credit Losses (along with related ASUs as disclosed in Note 3 - New Accounting Pronouncements) with a transition date of January 1, 2019 using the modified retrospective method. Upon adoption, there was no material impact to the Consolidated Financial Statements, and no adjustments were made to prior period financial statements.

Billed accounts receivable are recorded at the invoiced amount, net of allowance for doubtful accounts. Unbilled accounts receivable are recorded at their estimated value, net of allowance for doubtful accounts. Overdue amounts related to regulated billings bear

9

HYDRO ONE LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

For the years ended December 31, 2019 and 2018

interest at OEB-approved rates. The allowance for doubtful accounts reflects the Company’s current lifetime expected credit losses (CECL) for all accounts receivable balances. The Company estimates the CECL by applying internally developed loss rates to all outstanding receivable balances by aging category. Loss rates applied to the accounts receivable balances are based on historical overdue balances, customer payments and write-offs. Accounts receivable are written-off against the allowance when they are deemed uncollectible. The allowance for doubtful accounts is affected by changes in volume, prices and economic conditions.

Noncontrolling interest

Noncontrolling interest represents the portion of equity ownership in subsidiaries that is not attributable to shareholders of Hydro One. Noncontrolling interest is initially recorded at fair value and subsequently the amount is adjusted for the proportionate share of net income and other comprehensive income (OCI) attributable to the noncontrolling interest and any dividends or distributions paid to the noncontrolling interest.

If a transaction results in the acquisition of all, or part, of a noncontrolling interest in a subsidiary, the acquisition of the noncontrolling interest is accounted for as an equity transaction. No gain or loss is recognized in consolidated net income or comprehensive income as a result of changes in the noncontrolling interest, unless a change results in the loss of control by the Company.

Income Taxes

Current and deferred income taxes are computed based on the tax rates and tax laws enacted as at the balance sheet date. Tax benefits associated with income tax positions are recorded only when the more-likely-than-not recognition threshold is satisfied and are measured at the largest amount of benefit that has a greater than 50% likelihood of being realized upon settlement. Management evaluates each position based solely on the technical merits and facts and circumstances of the position, assuming the position will be examined by a taxing authority having full knowledge of all relevant information. Significant management judgment is required to determine recognition thresholds and the related amount of tax benefits to be recognized in the Consolidated Financial Statements. Management re-evaluates tax positions each period using new information about recognition or measurement as it becomes available.

Deferred Income Taxes

Deferred income taxes are provided for using the liability method. Under this method, deferred income tax assets and liabilities are recognized on all temporary differences between the tax bases and carrying amounts of assets and liabilities, including the carry forward unused tax credits and tax losses to the extent that it is more-likely-than-not that these deductions, credits, and losses can be utilized. Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply in the period when the liability is settled or the asset is realized, based on the tax rates and tax laws that have been enacted as at the balance sheet date. Deferred income taxes that are not included in the rate-setting process are charged or credited to the consolidated statements of operations and comprehensive income.

Management reassesses the deferred income tax assets at each balance sheet date and reduces the amount to the extent that it is more likely than not that the deferred income tax asset will not be realized. Previously unrecognized deferred income tax assets are reassessed at each balance sheet date and are recognized to the extent that it has become more likely than not that the tax benefit will be realized.

The Company recognizes deferred income taxes associated with its regulated operations and records offsetting regulatory assets and liabilities for the deferred income taxes that are expected to be recovered or refunded in future regulated rates charged to customers.

Investment tax credits are recorded as a reduction of the related expenses or income tax expense in the current or future period to the extent it is more likely than not that the credits can be utilized.

Materials and Supplies

Materials and supplies represent consumables, small spare parts and construction materials held for internal construction and maintenance of property, plant and equipment. These assets are carried at average cost less any impairments recorded.

Property, Plant and Equipment

Property, plant and equipment is recorded at original cost, net of customer contributions, and any accumulated impairment losses. The cost of additions, including betterments and replacement asset components, is included on the Consolidated Balance Sheets as property, plant and equipment.

The original cost of property, plant and equipment includes direct materials, direct labour (including employee benefits), contracted services, attributable capitalized financing costs, asset retirement costs, and direct and indirect overheads that are related to the capital project or program. Indirect overheads include a portion of corporate costs such as finance, treasury, human resources, and information technology (IT). Overhead costs, including corporate functions and field services costs, are capitalized on a fully allocated basis, consistent with an OEB-approved methodology.

10

HYDRO ONE LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

For the years ended December 31, 2019 and 2018

Property, plant and equipment in service consists of transmission, distribution, communication, administration and service assets and land easements. Property, plant and equipment also includes future use assets, such as land, major components and spare parts, and capitalized project development costs associated with deferred capital projects.

Transmission

Transmission assets include assets used for the transmission of high-voltage electricity, such as transmission lines, support structures, foundations, insulators, connecting hardware and grounding systems, and assets used to step up the voltage of electricity from generating stations for transmission and to step down voltages for distribution, including transformers, circuit breakers and switches.

Distribution

Distribution assets include assets related to the distribution of low-voltage electricity, including lines, poles, switches, transformers, protective devices and metering systems.

Communication

Communication assets include fibre optic and microwave radio systems, optical ground wire, towers, telephone equipment and associated buildings.

Administration and Service

Administration and service assets include administrative buildings, personal computers, transport and work equipment, tools and other minor assets.

Easements

Easements include statutory rights of use for transmission corridors and abutting lands granted under the Reliable Energy and Consumer Protection Act, 2002, as well as other land access rights.

Intangible Assets

Intangible assets separately acquired or internally developed are measured on initial recognition at cost, which comprises purchased software, direct labour (including employee benefits), consulting, engineering, overheads and attributable capitalized financing charges. Following initial recognition, intangible assets are carried at cost, net of any accumulated amortization and accumulated impairment losses. The Company’s intangible assets primarily represent major computer applications.

Capitalized Financing Costs

Capitalized financing costs represent interest costs attributable to the construction of property, plant and equipment or development of intangible assets. The financing cost of attributable borrowed funds is capitalized as part of the acquisition cost of such assets. The capitalized financing costs are a reduction of financing charges recognized in the Consolidated Statements of Operations and Comprehensive Income. Capitalized financing costs are calculated using the Company’s weighted average effective cost of debt.

Construction and Development in Progress

Construction and development in progress consists of the capitalized cost of constructed assets that are not yet complete and which have not yet been placed in service.

Depreciation and Amortization

The cost of property, plant and equipment and intangible assets is depreciated or amortized on a straight-line basis based on the estimated remaining service life of each asset category, except for transport and work equipment, which is depreciated on a declining balance basis.

The Company periodically initiates an external independent review of its property, plant and equipment and intangible asset depreciation and amortization rates, as required by the OEB. Any changes arising from OEB approval of such a review are implemented on a remaining service life basis, consistent with their inclusion in electricity rates. The most recent reviews resulted in changes to rates effective January 1, 2015 and January 1, 2017 for Hydro One Networks’ distribution and transmission businesses, respectively. A summary of average service lives and depreciation and amortization rates for the various classes of assets is included below:

	Average	Rate
	Service Life	Range	Average
Property, plant and equipment:
Transmission	55 years	1% - 3%	2	%
Distribution	46 years	1% - 7%	2	%
Communication	16 years	1% - 15%	5	%
Administration and service	21 years	1% - 20%	5	%
Intangible assets	10 years	10%	10	%

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

For the years ended December 31, 2019 and 2018

In accordance with group depreciation practices, the original cost of property, plant and equipment, or major components thereof, and intangible assets that are normally retired, is charged to accumulated depreciation, with no gain or loss being reflected in results of operations. Where a disposition of property, plant and equipment occurs through sale, a gain or loss is calculated based on proceeds and such gain or loss is included in depreciation expense.

Acquisitions and Goodwill

The Company accounts for business acquisitions using the acquisition method of accounting and, accordingly, the assets and liabilities of the acquired entities are primarily measured at their estimated fair value at the date of acquisition. Costs associated with pending acquisitions are expensed as incurred. Goodwill represents the cost of acquired companies that is in excess of the fair value of the net identifiable assets acquired at the acquisition date. Goodwill is not included in rate base.

Goodwill is evaluated for impairment on an annual basis, or more frequently if circumstances require. The Company performs a qualitative assessment to determine whether it is more likely than not that the fair value of the applicable reporting unit is less than its carrying amount. If the Company determines, as a result of its qualitative assessment, that it is not more likely than not that the fair value of the applicable reporting unit is less than its carrying amount, no further testing is required. If the Company determines, as a result of its qualitative assessment, that it is more likely than not that the fair value of the applicable reporting unit is less than its carrying amount, a goodwill impairment assessment is performed using a two-step, fair value-based test. The first step compares the fair value of the applicable reporting unit to its carrying amount, including goodwill. If the carrying amount of the applicable reporting unit exceeds its fair value, a second step is performed. The second step requires an allocation of fair value to the individual assets and liabilities using purchase price allocation in order to determine the implied fair value of goodwill. If the implied fair value of goodwill is less than the carrying amount, an impairment loss is recorded as a reduction to goodwill and as a charge to results of operations.

Based on assessment performed as at September 30, 2019, the Company has concluded that goodwill was not impaired at December 31, 2019.

Long-Lived Asset Impairment

When circumstances indicate the carrying value of long-lived assets may not be recoverable, the Company evaluates whether the carrying value of such assets, excluding goodwill, has been impaired. For such long-lived assets, the Company evaluates whether impairment may exist by estimating future estimated undiscounted cash flows expected to result from the use and eventual disposition of the asset. When alternative courses of action to recover the carrying amount of a long-lived asset are under consideration, a probability-weighted approach is used to develop estimates of future undiscounted cash flows. If the carrying value of the long-lived asset is not recoverable based on the estimated future undiscounted cash flows, an impairment loss is recorded, measured as the excess of the carrying value of the asset over its fair value. As a result, the asset’s carrying value is adjusted to its estimated fair value.

Within its regulated business, the carrying costs of most of Hydro One’s long-lived assets are included in rate base where they earn an OEB-approved rate of return. Asset carrying values and the related return are recovered through approved rates. As a result, such assets are only tested for impairment in the event that the OEB disallows recovery, in whole or in part, or if such a disallowance is judged to be probable.

Hydro One regularly monitors the assets of its unregulated Hydro One Telecom Inc. subsidiary for indications of impairment. Management assesses the fair value of such long-lived assets using commonly accepted techniques. Techniques used to determine fair value include, but are not limited to, the use of recent third-party comparable sales for reference and internally developed discounted cash flow analysis. Significant changes in market conditions, changes to the condition of an asset, or a change in management’s intent to utilize the asset are generally viewed by management as triggering events to reassess the cash flows related to these long-lived assets. As at December 31, 2019 and 2018, no asset impairment had been recorded for assets within either the Company’s regulated or unregulated businesses.

Costs of Arranging Debt Financing

For financial liabilities classified as other than held-for-trading and for convertible debentures, the Company defers the external transaction costs related to obtaining financing and presents such amounts net of related debt or convertible debentures on the Consolidated Balance Sheets. Deferred issuance costs are amortized over the contractual life of the related debt or convertible debentures on an effective-interest basis and the amortization is included within financing charges in the Consolidated Statements of Operations and Comprehensive Income. Transaction costs for items classified as held-for-trading are expensed immediately.

Comprehensive Income

Comprehensive income is comprised of net income and OCI. Hydro One presents net income and OCI in a single continuous Consolidated Statement of Operations and Comprehensive Income.

Financial Assets and Liabilities

All financial assets and liabilities are classified into one of the following five categories: held-to-maturity; loans and receivables; held-for-trading; other liabilities; or available-for-sale. Financial assets and liabilities classified as held-for-trading are measured at

fair value. All other financial assets and liabilities are measured at amortized cost, except accounts receivable and amounts due from related parties, which are measured at the lower of cost or fair value. Accounts receivable and amounts due from related parties are classified as loans and receivables. The Company considers the carrying amounts of accounts receivable and amounts due from related parties to be reasonable estimates of fair value because of the short time to maturity of these instruments. The Company estimates the CECL for all accounts receivable balances, which are recognized as adjustments to the allowance for doubtful accounts. Accounts receivable are written-off against the allowance when they are deemed uncollectible. All financial instrument transactions are recorded at trade date.

The Company determines the classification of its financial assets and liabilities at the date of initial recognition. The Company designates certain of its financial assets and liabilities to be held at fair value, when it is consistent with the Company’s risk management policy disclosed in Note 18 - Fair Value of Financial Instruments and Risk Management.

Derivative Instruments and Hedge Accounting

The Company closely monitors the risks associated with changes in interest rates on its operations and, where appropriate, uses various instruments to hedge these risks. Certain of these derivative instruments qualify for hedge accounting and are designated as accounting hedges, while others either do not qualify as hedges or have not been designated as hedges (hereinafter referred to as undesignated contracts) as they are part of economic hedging relationships.

The accounting guidance for derivative instruments requires the recognition of all derivative instruments not identified as meeting the normal purchase and sale exemption as either assets or liabilities recorded at fair value on the consolidated balance sheets. For derivative instruments that qualify for hedge accounting, the Company may elect to designate such derivative instruments as either cash flow hedges or fair value hedges. The Company offsets fair value amounts recognized on its consolidated balance sheets related to derivative instruments executed with the same counterparty under the same master netting agreement.

For derivative instruments that qualify for hedge accounting and which are designated as cash flow hedges, any unrealized gain or loss, net of tax, is recorded as a component of accumulated OCI (AOCI). Amounts in AOCI are reclassified to results of operations in the same period or periods during which the hedged transaction affects results of operations and presented in the same line item as the earnings effect of the hedged item. Any gains or losses on the derivative instrument that represent hedge components excluded from the assessment of effectiveness are recognized in the same line item of the consolidated statements of operations as the hedged item. For fair value hedges, changes in fair value of both the derivative instrument and the underlying hedged exposure are recognized in the consolidated statements of operations and comprehensive income in the current period. The gain or loss on the derivative instrument is included in the same line item as the offsetting gain or loss on the hedged item in the consolidated statements of operations and comprehensive income. The changes in fair value of the undesignated derivative instruments are reflected in results of operations.

Embedded derivative instruments are separated from their host contracts and are carried at fair value on the consolidated balance sheets when: (a) the economic characteristics and risks of the embedded derivative are not clearly and closely related to the economic characteristics and risks of the host contract; (b) the hybrid instrument is not measured at fair value, with changes in fair value recognized in results of operations each period; and (c) the embedded derivative itself meets the definition of a derivative. The Company does not engage in derivative trading or speculative activities and had no embedded derivatives that required bifurcation at December 31, 2019 or 2018.

Hydro One periodically develops hedging strategies taking into account risk management objectives. At the inception of a hedging relationship where the Company has elected to apply hedge accounting, Hydro One formally documents the relationship between the hedged item and the hedging instrument, the related risk management objective, the nature of the specific risk exposure being hedged, and the method for assessing the effectiveness of the hedging relationship. The Company also assesses, both at the inception of the hedge and on a quarterly basis, whether the hedging instruments are effective in offsetting changes in fair values or cash flows of the hedged items.

Employee Future Benefits

Employee future benefits provided by Hydro One include pension, post-retirement and post-employment benefits. The costs of the Company’s pension, post-retirement and post-employment benefit plans are recorded over the periods during which employees render service.

The Company recognizes the funded status of its defined benefit pension, post-retirement and post-employment plans on its consolidated balance sheets and subsequently recognizes the changes in funded status at the end of each reporting year. Defined benefit pension, post-retirement and post-employment plans are considered to be underfunded when the projected benefit obligation (PBO) exceeds the fair value of the plan assets. Liabilities are recognized on the consolidated balance sheets for any net underfunded PBO. The net underfunded PBO may be disclosed as a current liability, long-term liability, or both. The current portion is the amount by which the actuarial present value of benefits included in the benefit obligation payable in the next 12 months exceeds the fair value of plan assets. If the fair value of plan assets exceeds the PBO of the plan, an asset is recognized equal to the net overfunded PBO. The post-retirement and post-employment benefit plans are unfunded because there are no related plan assets.

Hydro One recognizes its contributions to the defined contribution pension plan (DC Plan) as pension expense, with a portion being capitalized as part of labour costs included in capital expenditures. The expensed amount is included in operation, maintenance and administration (OM&A) costs in the consolidated statements of operations and comprehensive income.

Defined Benefit Pension

Defined benefit pension costs are recorded on an accrual basis for financial reporting purposes. Pension costs are actuarially determined using the projected benefit method prorated on service and are based on assumptions that reflect management’s best estimate of the effect of future events, including future compensation increases. Past service costs from plan amendments and all actuarial gains and losses are amortized on a straight-line basis over the expected average remaining service period of active employees in the plan, and over the estimated remaining life expectancy of inactive employees in the plan. Pension plan assets, consisting primarily of listed equity securities, corporate and government debt securities as well as private real estate and private infrastructure investments, are recorded at fair value at the end of each year. Hydro One records a regulatory asset equal to the net underfunded PBO for its pension plan. Defined benefit pension costs are attributed to labour costs on a cash basis and a portion directly related to acquisition and development of capital assets is capitalized as part of the cost of property, plant and equipment and intangible assets. The remaining defined benefit pension costs are charged to results of operations (OM&A costs).

Post-retirement and Post-employment Benefits

Post-retirement and post-employment benefits are recorded and included in rates on an accrual basis. Costs are determined by independent actuaries using the projected benefit method prorated on service and based on assumptions that reflect management’s best estimates. Past service costs from plan amendments are amortized to results of operations based on the expected average remaining service period.

For post-retirement benefits, all actuarial gains or losses are deferred using the “corridor” approach. The amount calculated above the “corridor” is amortized to results of operations on a straight-line basis over the expected average remaining service life of active employees in the plan and over the remaining life expectancy of inactive employees in the plan. The post-retirement benefit obligation is remeasured to its fair value at each year end based on an annual actuarial report, with an offset to the associated regulatory asset, to the extent of the remeasurement adjustment.

For post-employment obligations, the associated regulatory liabilities representing actuarial gains on transition to US GAAP are amortized to results of operations based on the “corridor” approach. The actuarial gains and losses on post-employment obligations that are incurred during the year are recognized immediately to results of operations. The post-employment benefit obligation is remeasured to its fair value at each year end based on an annual actuarial report, with an offset to the associated regulatory asset, to the extent of the remeasurement adjustment.

All post-retirement and post-employment benefit costs are attributed to labour costs and are either charged to results of operations (OM&A costs) or capitalized as part of the cost of property, plant and equipment and intangible assets for service cost component and to regulatory assets for all other components of the benefit costs, consistent with their inclusion in OEB-approved rates.

Stock-Based Compensation

Share Grant Plans

Hydro One measures share grant plans based on fair value of share grants as estimated based on the grant date common share price. The costs are recognized in the financial statements using the graded-vesting attribution method for share grant plans that have both a performance condition and a service condition. The Company records a regulatory asset equal to the accrued costs of share grant plans recognized in each period. Costs are transferred from the regulatory asset to labour costs at the time the share grants vest and are issued, and are recovered in rates. Forfeitures are recognized as they occur.

Deferred Share Unit (DSU) Plans

The Company records the liabilities associated with its Directors’ and Management DSU Plans at fair value at each reporting date until settlement, recognizing compensation expense over the vesting period on a straight-line basis. The fair value of the DSU liability is based on the Company’s common share closing price at the end of each reporting period.

Long-term Incentive Plan (LTIP)

The Company measures the awards issued under its LTIP, at fair value based on the grant date common share price. The related compensation expense is recognized over the vesting period on a straight-line basis. Forfeitures are recognized as they occur.

Loss Contingencies

Hydro One is involved in certain legal and environmental matters that arise in the normal course of business. In the preparation of its Consolidated Financial Statements, management makes judgments regarding the future outcome of contingent events and records a loss for a contingency based on its best estimate when it is determined that such loss is probable and the amount of the loss can be reasonably estimated. Where the loss amount is recoverable in future rates, a regulatory asset is also recorded. When a range estimate for the probable loss exists and no amount within the range is a better estimate than any other amount, the Company records a loss at the minimum amount within the range.

Management regularly reviews current information available to determine whether recorded provisions should be adjusted and whether new provisions are required. Estimating probable losses may require analysis of multiple forecasts and scenarios that often depend on judgments about potential actions by third parties, such as federal, provincial and local courts or regulators. Contingent liabilities are often resolved over long periods of time. Amounts recorded in the Consolidated Financial Statements may differ from the actual outcome once the contingency is resolved. Such differences could have a material impact on future results of operations, financial position and cash flows of the Company.

Provisions are based upon current estimates and are subject to greater uncertainty where the projection period is lengthy. A significant upward or downward trend in the number of claims filed, the nature of the alleged injuries, and the average cost of resolving each claim could change the estimated provision, as could any substantial adverse or favourable verdict at trial. A federal or provincial legislative outcome or structured settlement could also change the estimated liability. Legal fees are expensed as incurred.

Environmental Liabilities

Environmental liabilities are recorded in respect of past contamination when it is determined that future environmental remediation expenditures are probable under existing statute or regulation and the amount of the future expenditures can be reasonably estimated. Hydro One records a liability for the estimated future expenditures associated with contaminated land assessment and remediation (LAR) and for the phase-out and destruction of polychlorinated biphenyl (PCB)-contaminated mineral oil removed from electrical equipment, based on the present value of these estimated future expenditures. The Company determines the present value with a discount rate that produces an amount at which the environmental liabilities could be settled in an arm’s length transaction with a third party. As the Company anticipates that the future expenditures will continue to be recoverable in future rates, an offsetting regulatory asset has been recorded to reflect the future recovery of these environmental expenditures from customers. Hydro One reviews its estimates of future environmental expenditures annually, or more frequently if there are indications that circumstances have changed.

Asset Retirement Obligations

Asset retirement obligations are recorded for legal obligations associated with the future removal and disposal of long-lived assets. Such obligations may result from the acquisition, construction, development and/or normal use of the asset. Conditional asset retirement obligations are recorded when there is a legal obligation to perform a future asset retirement activity but where the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the Company. In such a case, the obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and/or method of settlement. This uncertainty is incorporated in the fair value measurement of the obligation.

When recording an asset retirement obligation, the present value of the estimated future expenditures required to complete the asset retirement activity is recorded in the period in which the obligation is incurred, if a reasonable estimate can be made. In general, the present value of the estimated future expenditures is added to the carrying amount of the associated asset and the resulting asset retirement cost is depreciated over the estimated useful life of the asset. The present value is determined with a discount rate that equates to the Company’s credit-adjusted risk-free rate. Where an asset is no longer in service when an asset retirement obligation is recorded, the asset retirement cost is recorded in results of operations.

Some of the Company’s transmission and distribution assets, particularly those located on unowned easements and rights-of-way, may have asset retirement obligations, conditional or otherwise. The majority of the Company’s easements and rights-of-way are either of perpetual duration or are automatically renewed annually. Land rights with finite terms are generally subject to extension or renewal. As the Company expects to use the majority of its facilities in perpetuity, no asset retirement obligations have been recorded for these assets. If, at some future date, a particular facility is shown not to meet the perpetuity assumption, it will be reviewed to determine whether an estimable asset retirement obligation exists. In such a case, an asset retirement obligation would be recorded at that time.

The Company’s asset retirement obligations recorded to date relate to estimated future expenditures associated with the removal and disposal of asbestos-containing materials installed in some of its facilities.

Leases

Effective January 1, 2019, the Company adopted Accounting Standards Codification (ASC) 842 - Leases using the modified retrospective transition approach using the effective date of January 1, 2019, as its date of initial application. In the Company's transition to ASC 842, the Company elected the package of practical expedients and the land easement practical expedient. As a result, a Right-of-Use (ROU) asset and a corresponding lease obligation of approximately $27 million was recognized on the

15

HYDRO ONE LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

For the years ended December 31, 2019 and 2018

Consolidated Balance Sheet at January 1, 2019, and no adjustments were made to prior period financial statement amounts. There was no material impact to the Consolidated Statement of Operations and Comprehensive Income. On adoption, the Company did not identify any finance leases.

At the commencement date of a lease, the minimum lease payments are discounted and recognized as a lease obligation. Discount rates used correspond to the Company's incremental borrowing rates. Renewal options are assessed for their likelihood of being exercised and are included in the measurement of the lease obligation when it is reasonably certain they will be exercised. The Company does not recognize leases with a term of less than 12 months. A corresponding ROU asset is recognized at the commencement date of a lease. The ROU asset is measured as the lease obligation adjusted for any lease payments made and/or any lease incentives and initial direct costs incurred. ROU assets are included in other long-term assets, and corresponding lease obligations are included in other current liabilities and other long-term liabilities on the Consolidated Balance Sheets.

Subsequent to the commencement date, the lease expense recognized at each reporting period is the total remaining lease payments over the remaining lease term. Lease obligations are measured as the present value of the remaining unpaid lease payments using the discount rate established at commencement date. The amortization of the ROU assets are calculated as the difference between the lease expense and the accretion of interest, which is calculated on the effective interest method. Lease modifications and impairments are assessed at each reporting period to assess the need for a re-measurement of the lease obligations or ROU assets.

4. BUSINESS COMBINATIONS

NRLP

In 2018, Hydro One entered into an agreement with the First Nations Partners, wherein a noncontrolling equity interest in Hydro One’s limited partnership, NRLP, would be made available for purchase at fair value by the First Nations Partners. On September 19, 2018, NRLP was formed to own a new 230 kV transmission line (Niagara Line) in the Niagara region. The Niagara Line enables generators in the Niagara area to connect to the load centres of the Greater Toronto and Hamilton areas. Hydro One Networks maintains and operates the Niagara Line in accordance with an operation and management services agreement. On September 12, 2019, the OEB granted NRLP a transmission licence and granted Hydro One Networks leave to sell the applicable Niagara Line assets to NRLP.

On September 18, 2019, the applicable Niagara Line assets were transferred from Hydro One Networks to NRLP for $119 million and operation of the line was contracted to Hydro One Networks. This transfer was financed with 60% debt ($71 million) and 40% equity ($48 million). The cash payment of $71 million was financed by debt sourced by NRLP from a Hydro One subsidiary, and the $48 million equity comprised partnership units issued by NRLP to Hydro One Networks. Subsequently, on the same date, Hydro One Networks sold to the Six Nations of the Grand River Development Corporation and to the Mississaugas of the Credit First Nation, through a trust, a 25.0% and 0.1%, respectively, equity interest in NRLP for total consideration of $12 million, representing the fair value of the equity interest acquired.

NRLP is fully consolidated in these Consolidated Financial Statements as it is controlled by Hydro One. The First Nations Partners' 25.1% noncontrolling interest in NRLP is classified within equity. Net income attributable to the First Nations Partners' noncontrolling interest for the period from September 18, 2019 to December 31, 2019 was not significant. See Note 28 - Noncontrolling Interest for additional information.

In addition, the Mississaugas of the Credit First Nation had an option to purchase an additional 19.9% equity interest in NRLP from Hydro One Networks at a price based on the value of the Niagara Line assets on the date of closing, subject to certain conditions. On December 31, 2019, the Mississaugas of the Credit First Nation exercised the option. The transaction closed on January 31, 2020. See Note 34 - Subsequent Events for additional information.

Avista Corporation Purchase Agreement

In July 2017, Hydro One reached an agreement to acquire Avista Corporation (Merger). On January 23, 2019, Hydro One and Avista Corporation announced that the companies have mutually agreed to terminate the Merger agreement. As a result of the termination of the Merger agreement, on January 24, 2019, Hydro One paid a US$103 million termination fee to Avista Corporation as required by the Merger agreement. In January 2019, the Company cancelled the $1.0 billion non-revolving equity bridge credit facility and the US$2.6 billion non-revolving debt bridge credit facility (Acquisition Credit Facilities), with no amounts drawn. On February 1, 2019, Hydro One entered into a credit agreement for a $170 million unsecured demand operating credit facility (Demand Facility) which was used to fund the payment of the Merger termination fee and other Merger-related costs. On June 6, 2019, the $170 million drawn on the Demand Facility was repaid, and the Demand Facility is no longer available. On February 8, 2019, Hydro One redeemed the convertible debentures and paid the holders of the Instalment Receipts $513 million ($333 per $1,000 principal amount) plus accrued and unpaid interest of $7 million. The redemption of the convertible debentures was paid with cash on hand. As a result of the termination of the Merger agreement, the deal-contingent foreign-exchange forward contract (Foreign-Exchange Contract) terminated, with no amounts paid or received by Hydro One.

The following amounts related to the termination of the Merger agreement were recorded by the Company during the year ended December 31, 2019. All amounts were recognized in the first quarter.

•	$138 million for payment of the US$103 million Merger termination fee recorded in operation, maintenance and administration costs;
•	$22 million financing charges, due to reversal of previously recorded unrealized gains upon termination of the Foreign-Exchange Contract;
---	---
•	redemption of $513 million convertible debentures and payment of related interest of $7 million; and

Orillia Power Purchase Agreement

In August 2016, the Company reached an agreement to acquire Orillia Power Distribution Corporation (Orillia Power), an electricity distribution company located in Simcoe County, Ontario, from the City of Orillia for approximately $41 million, including the assumption of approximately $15 million in outstanding indebtedness and regulatory liabilities, subject to closing adjustments and regulatory approval by the OEB. In 2016, Hydro One filed an application with the OEB to acquire Orillia Power, which was denied by the OEB in April 2018. In September 2018, Hydro One filed a new application with the OEB for approval to acquire Orillia Power. An OEB oral hearing was held on December 2-3, 2019. A decision by the OEB is pending.

Peterborough Distribution Purchase Agreement

In July 2018, Hydro One reached an agreement to acquire the business and distribution assets of Peterborough Distribution Inc., an electricity distribution company located in east central Ontario, from the City of Peterborough for approximately $105 million. The acquisition is conditional upon the satisfaction of customary closing conditions and approval by the OEB and the Competition Bureau. In October 2018, the Company filed an application with the OEB for approval of the acquisition. In November 2018, the Competition Bureau issued no action letter, meaning that transaction can proceed from the Competition Bureau’s position. An OEB oral hearing was held on December 2-3, 2019. A decision by the OEB is pending.

Deferred Income Tax Assets and Liabilities

Deferred income tax assets and liabilities that are expected to be included in the rate-setting process are offset by regulatory assets and liabilities to reflect the anticipated recovery or disposition of these balances within future electricity rates. Deferred income tax assets and liabilities arise from differences between the tax basis and the carrying amounts of the assets and liabilities. At December 31, 2019 and 2018, deferred income tax assets and liabilities consisted of the following:

December 31 (millions of dollars)	2019		2018

Deferred Income Tax Regulatory Asset and Liability

Deferred income taxes are recognized on temporary differences between the carrying amount of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable income. The Company has recognized regulatory assets and liabilities that correspond to deferred income taxes that flow through the rate-setting process. In the absence of rate-regulated accounting, the Company’s income tax expense would have been recognized using the liability method and there would be no regulatory accounts established for taxes to be recovered through future rates. As a result, the 2019 income tax expense would have been higher by approximately $221 million (2018 - lower by $686 million).

On September 28, 2017, the OEB issued its decision and order on Hydro One Networks' 2017 and 2018 transmission rates revenue requirements (Original Decision). In its Original Decision, the OEB concluded that the net deferred tax asset resulting from transition from the payments in lieu of tax regime under the Electricity Act, 1998 (Ontario) to tax payments under the federal and provincial tax regime should not accrue entirely to Hydro One shareholders and that a portion should be shared with ratepayers. On November 9, 2017, the OEB issued a decision and order that calculated the portion of the tax savings that should be shared with ratepayers. The OEB's calculation would result in an impairment of a portion of both Hydro One Networks' transmission and distribution deferred income tax regulatory asset. In October 2017, the Company filed a Motion to Review and Vary (Motion) the Original Decision and filed an appeal with the Ontario Divisional Court (Appeal). In both cases, the Company's position was that the OEB made errors of fact and law in its determination of allocation of the tax savings between the shareholders and ratepayers. On December 19, 2017, the OEB granted a hearing of the merits of the Motion which was held on February 12, 2018. On August 31, 2018, the OEB granted the Motion and returned the portion of the Original Decision relating to the deferred tax asset to an OEB panel for reconsideration.

On March 7, 2019, the OEB issued its reconsideration decision and concluded that their Original Decision was reasonable and should be upheld. Also, on March 7, 2019 the OEB issued its decision for Hydro One Networks’ 2018-2022 distribution rates, in which it directed the Company to apply the Original Decision to Hydro One Networks’ distribution rates. As a result, as at December 31, 2018, the Company recognized an impairment charge of Hydro One Networks' distribution deferred income tax regulatory asset of $474 million and Hydro One Networks' transmission deferred income tax regulatory asset of $558 million, an increase in deferred income tax regulatory liability of $81 million, and a decrease in the foregone revenue deferral regulatory asset of $68 million. The

22

HYDRO ONE LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

For the years ended December 31, 2019 and 2018

regulatory balances relating to deferred tax asset sharing will continue to decrease as the tax savings are shared with ratepayers. Notwithstanding the recognition of the effects of the decision in the financial statements, on April 5, 2019, the Company filed an appeal with the Ontario Divisional Court with respect to the OEB's deferred tax benefit decision. The appeal was heard on November 21, 2019 and a decision is pending.

Pension Benefit Regulatory Asset

In accordance with OEB rate orders, pension costs are recovered on a cash basis as employer contributions are paid to the pension fund in accordance with the Pension Benefits Act (Ontario). The Company recognizes the net unfunded status of pension obligations on the Consolidated Balance Sheets with an offset to the associated regulatory asset. A regulatory asset is recognized because management considers it to be probable that pension benefit costs will be recovered in the future through the rate-setting process. The pension benefit obligation is remeasured to the present value of the actuarially determined benefit obligation at each year end based on an annual actuarial report, with an offset to the associated regulatory asset, to the extent of the remeasurement adjustment. In the absence of rate-regulated accounting, OCI would have been lower by $597 million (2018 - higher by $435 million) and OM&A expenses would have been lower by $20 million (2018 - higher by $1 million).

Environmental

Hydro One records a liability for the estimated future expenditures required to remediate environmental contamination. A regulatory asset is recognized because management considers it to be probable environmental expenditures will be recovered in the future through the rate-setting process. The Company has recorded an equivalent amount as a regulatory asset. In 2019, the environmental regulatory asset decreased by $3 million (2018 - $15 million) to reflect related changes in the Company’s PCB and LAR environmental liabilities. The environmental regulatory asset is amortized to results of operations based on the pattern of actual expenditures incurred and charged to environmental liabilities. The OEB has the discretion to examine and assess the prudency and the timing of recovery of all of Hydro One’s actual environmental expenditures. In the absence of rate-regulated accounting, 2019 OM&A expenses would have been lower by $3 million (2018 - $15 million). In addition, 2019 amortization expense would have been lower by $25 million (2018 - $22 million), and 2019 financing charges would have been higher by $4 million (2018 - $6 million).

Post-Retirement and Post-Employment Benefits

In accordance with OEB rate orders, post-retirement and post-employment benefits costs are recovered on an accrual basis. The Company recognizes the net unfunded status of post-retirement and post-employment obligations on the Consolidated Balance Sheets with an incremental offset to the associated regulatory assets. A regulatory asset is recognized because management considers it to be probable that post-retirement and post-employment benefit costs will be recovered in the future through the rate-setting process. The post-retirement and post-employment benefit obligation is remeasured to the present value of the actuarially determined benefit obligation at each year end based on an annual actuarial report, with an offset to the associated regulatory asset or liability as the case may be, to the extent of the remeasurement adjustment. In the absence of rate-regulated accounting, 2019 OCI would have been lower by $235 million (2018 - higher by $166 million).

Post-Retirement and Post-Employment Benefits - Non-Service Cost

Hydro One applied to the OEB for a regulatory asset account to record the components other than service costs relating to its post-retirement and post-employment benefits that would have previously been capitalized to property, plant and equipment and intangible assets prior to adoption of ASU 2017-07. In May 2018 and March 2019, the OEB approved the regulatory asset account for Hydro One Networks' transmission business and distribution business, respectively. Hydro One has recorded the components other than service costs relating to its post-retirement and post-employment benefits that would have been capitalized to property, plant and equipment and intangible assets, in the Post-Retirement and Post-Employment Benefits - Non-Service Cost regulatory asset. Hydro One proposed disposition methodologies for the accumulated balance in the 2020-2022 transmission rate application which is pending an OEB decision.

Foregone Revenue Deferral

The foregone revenue deferral account is primarily made up of the difference between revenue earned based on distribution rates approved by the OEB in Hydro One Networks' 2018-2022 distribution rates application, effective May 1, 2018, and revenue earned under the interim rates until the approved 2018 and 2019 rates were implemented on July 1, 2019. The balance of this account is being recovered from ratepayers over an 18-month period ending December 31, 2020. The foregone revenue deferral account also records the difference between revenue earned based on transmission rates approved by the OEB in Hydro One Networks' 2019 transmission rate application, effective May 1, 2019, and the revenue earned under the interim rates until the approved 2019 rates were implemented on July 1, 2019. The balance of this account was being recovered from ratepayers over a 6-month period ended December 31, 2019. The 2019 revenue requirement related to NRLP (see Note 1 - Description of the Business and Note 4 - Business Combinations) is also recorded in this account.

Stock-based Compensation

The Company recognizes costs associated with share grant plans in a regulatory asset as management considers it probable that share grant plans' costs will be recovered in the future through the rate-setting process. In the absence of rate-regulated accounting, there would be no material impact to OM&A expenses (2018 - OM&A expenses would be higher by $1 million). Share grant costs

23

HYDRO ONE LIMITED

For the years ended December 31, 2019 and 2018

are transferred to labour costs at the time the share grants vest and are issued, and are recovered in rates in accordance with recovery of said labour costs.

Debt Premium

The value of debt assumed in the acquisition of HOSSM has been recorded at fair value in accordance with US GAAP - Business Combinations. The OEB allows for recovery of interest at the coupon rate of the Senior Secured Bonds and a regulatory asset has been recorded for the difference between the fair value and face value of this debt. The debt premium is recovered over the remaining term of the debt.

Distribution System Code (DSC) Exemption

In June 2010, Hydro One Networks filed an application with the OEB regarding the OEB’s new cost responsibility rules contained in the OEB’s October 2009 Notice of Amendment to the DSC, with respect to the connection of certain renewable generators that were already connected or that had received a connection impact assessment prior to October 21, 2009. The application sought approval to record and defer the unanticipated costs incurred by Hydro One Networks that resulted from the connection of certain renewable generation facilities. The OEB ruled that identified specific expenditures can be recorded in a deferral account subject to the OEB’s review in subsequent Hydro One Networks distribution applications. In 2015, the OEB also approved Hydro One’s request to discontinue this deferral account. The remaining balance in this account at December 31, 2016, including accrued interest, was approved for disposition by the OEB in March 2019, and was transferred to the 2019-2020 Rate Rider.

Tax Rule Changes Variance

The 2019 federal and Ontario budgets (Budgets) provided certain time-limited investment incentives permitting Hydro One to deduct accelerated capital cost allowance of up to three times the first-year rate for capital investments acquired after November 20, 2018 and placed in-service before January 1, 2028. The Budgets measures enacted in the second quarter of 2019 required Hydro One to refund the tax benefits related to the accelerated depreciation rules to ratepayers. The tax benefit to be returned to ratepayers in the future gave rise to a regulatory liability and resulted in a decrease in revenues as current rates do not include the benefit of the accelerated tax; therefore, the revenue subject to refund cannot be recognized.

Distribution Rate Riders

In March 2019, as part of its decision on Hydro One Networks' distribution rates application for 2018-2022, the OEB approved the disposition of certain deferral and variance accounts which were accumulated in a 2019-2020 Rate Rider. The Distribution Rate Riders balance includes the 2019-2020 Rate Rider, where amounts are currently being disposed of over an 18-month period ending December 31, 2020, and the 2015-2017 Rate Rider balance, representing over-collected amounts to be returned to ratepayers in a future rate application.

Pension Cost Differential

Variances between the pension cost recognized and the cost embedded in rates as part of the rate-setting process for Hydro One Networks' transmission business are recognized as a regulatory asset or regulatory liability, as the case may be. Similar variances were recognized for the distribution business prior to January 1, 2018, but are no longer recognized based on the March 7, 2019 decision. In March 2019, the OEB approved the disposition of the distribution business portion of the balance as at December 31, 2016, including accrued interest, and the balance was transferred to the 2019-2020 Rate Rider. The transmission portion of the balance as at December 31, 2018, including accrued interest, was requested for disposition in the 2020-2022 transmission rate application. On March 26, 2019, the Company filed a motion to review and vary the OEB's decision as it relates to rates revenue requirement recovery of employer pension costs. Concurrently, the Company filed an appeal with the Ontario Divisional Court. The appeal was held in abeyance pending the outcome of the motion made before the OEB. During the year, the Company reflected a portion of pension costs incurred in the Hydro One Networks' distribution Pension Cost Differential regulatory account, pending the outcome of the motion before the OEB. On December 19, 2019, the OEB affirmed its earlier decision with respect to recovery of the revenue requirement associated with pension costs. As a result, Hydro One derecognized the portion relating to pension costs charged to operations as a reversal of revenues of $13 million as this amount is no longer probable for recovery. Hydro One also transferred to property, plant and equipment and intangible assets the portion attributable to capital expenditures in the amount of $37 million. Hydro One has decided to discontinue its appeal of the OEB decision with the Ontario Divisional Court. In the absence of rate-regulated accounting, 2019 revenue would have been higher by $5 million (2018 - $29 million).

Green Energy Expenditure Variance

In April 2010, the OEB requested the establishment of deferral accounts which capture the difference between the revenue recorded on the basis of Green Energy Plan expenditures incurred and the actual recoveries received. The smart grid variance account balance as at December 31, 2016, including accrued interest, was approved for disposition by the OEB in March 2019, and was transferred to the 2019-2020 Rate Rider.

Retail Settlement Variance Account (RSVA)

Hydro One has deferred certain retail settlement variance amounts under the provisions of Article 490 of the OEB’s Accounting Procedures Handbook. The RSVA account tracks the difference between the cost of power purchased from the Independent

24

HYDRO ONE LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

Electricity System Operator (IESO) and the cost of power recovered from ratepayers. The balance as at December 31, 2014, including accrued interest, was approved for disposition by the OEB in March 2019, and was transferred to the 2019-2020 Rate Rider.

Earnings Sharing Mechanism Deferral

In March 2019, the OEB approved the establishment of an earnings sharing mechanism deferral account for Hydro One Networks distribution to record over-earnings, if any, realized for any year from 2018 to 2022. Under this mechanism, Hydro One shares 50% of regulated earnings that exceed the OEB-approved regulatory return-on-equity by more than 100 basis points with distribution ratepayers. This account is asymmetrical to the benefit of ratepayers.

External Revenue Variance

The external revenue variance account balance reflects the difference between actual export service revenue and external revenues from secondary land use, and the OEB-approved amounts. The account also records the difference between actual net external station maintenance, engineering and construction services revenue, and other external revenue, and the OEB-approved amounts. In September 2017, the OEB approved the disposition of the external revenue variance account as at December 31, 2015, including accrued interest, which was returned to customers over a two-year period ended December 31, 2018. The balance as at December 31, 2018, including accrued interest, was requested for disposition in the 2020-2022 transmission rate application.

The unrealized mark-to-market net loss is offset by a $1 million unrealized mark-to-market net gain (2018 - $5 million net loss) on the related fixed-to-floating interest-rate swap agreements, which are accounted for as fair value hedges.

(a) Hydro One Inc. long-term debt

At December 31, 2019, long-term debt of $11,345 million (2018 - $10,573 million) was outstanding, the majority of which was issued under Hydro One Inc.’s Medium Term Note (MTN) Program. The maximum authorized principal amount of notes issuable under the current MTN Program prospectus filed in March 2018 is $4,000 million. At December 31, 2019, $1,100 million remained available for issuance until April 2020.

In 2019, Hydro One Inc. issued long-term debt totalling $1,500 million (2018 - $1,400 million) and repaid long-term debt of $728 million (2018 - $750 million) under its MTN Program.

17. CONVERTIBLE DEBENTURES

The following table presents the change in convertible debentures during the years ended December 31, 2019 and 2018:

Year ended December 31 (millions of dollars)	2019		2018
Carrying value - beginning	489		487

Derecognition of deferred financing costs (Notes 4, 6)	24		—
Redemption (Note 4)	(513	)	—
Carrying value - ending	—		489
Face value - ending	—		513

In August 2017, in connection with the proposed Merger (see Note 4 - Business Combinations), the Company completed the sale (Debenture Offering) of $1,540 million aggregate principal amount of 4.00% convertible unsecured subordinated debentures (Convertible Debentures). The Convertible Debentures were sold on an instalment basis at a price of $1,000 per Convertible Debenture, of which $333 (Initial Instalment) was paid on closing of the Debenture Offering and the remaining $667 (Final Instalment) would have been payable following the satisfaction of certain conditions precedent to the closing of the Merger. The gross proceeds received from the Initial Instalment were $513 million. The Company incurred financing costs of $27 million, which had been initially deferred and were being amortized to financing charges.

As a result of the termination of the Merger agreement (see Note 4 - Business Combinations), on February 8, 2019, Hydro One redeemed the Convertible Debentures and paid the holders of the instalment receipts $513 million ($333 per $1,000 principal amount) plus accrued and unpaid interest of $7 million. In addition, unamortized deferred financing costs of $24 million were derecognized and expensed in financing charges. The interest expense recorded in 2019 was $7 million (2018 - $62 million).

18. FAIR VALUE OF FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

Fair value is considered to be the exchange price in an orderly transaction between market participants to sell an asset or transfer a liability at the measurement date. The fair value definition focuses on an exit price, which is the price that would be received in the sale of an asset or the amount that would be paid to transfer a liability.

28

HYDRO ONE LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

For the years ended December 31, 2019 and 2018

Hydro One classifies its fair value measurements based on the following hierarchy, as prescribed by the accounting guidance for fair value, which prioritizes the inputs to valuation techniques used to measure fair value into three levels:

Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that Hydro One has the ability to access. An active market for the asset or liability is one in which transactions for the asset or liability occur with sufficient frequency and volume to provide ongoing pricing information.

Level 2 inputs are those other than quoted market prices that are observable, either directly or indirectly, for an asset or liability. Level 2 inputs include, but are not limited to, quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active and inputs other than quoted market prices that are observable for the asset or liability, such as interest-rate curves and yield curves observable at commonly quoted intervals, volatilities, credit risk and default rates. A Level 2 measurement cannot have more than an insignificant portion of the valuation based on unobservable inputs.

Level 3 inputs are any fair value measurements that include unobservable inputs for the asset or liability for more than an insignificant portion of the valuation. A Level 3 measurement may be based primarily on Level 2 inputs.

Non-Derivative Financial Assets and Liabilities

At December 31, 2019 and 2018, the Company’s carrying amounts of cash and cash equivalents, accounts receivable, due from related parties, short-term notes payable, accounts payable, and due to related parties are representative of fair value due to the short-term nature of these instruments.

Fair Value Measurements of Long-Term Debt

The fair values and carrying values of the Company’s long-term debt at December 31, 2019 and 2018 are as follows:

	2019	2019	2018	2018
December 31 (millions of dollars)	Carrying Value	Fair Value	Carrying Value	Fair Value
Long-term debt measured at fair value:
$50 million of MTN Series 33 notes	50	50	49	49

Long-term debt, including current portion	11,475	13,472	10,709	11,665

Fair Value Measurements of Derivative Instruments

Fair Value Hedges

At December 31, 2019, Hydro One Inc. had interest-rate swaps with a total notional amount of $350 million (2018 - $850 million) that were used to convert fixed-rate debt to floating-rate debt. These swaps are classified as fair value hedges. Hydro One Inc.’s fair value hedge exposure was approximately 3% (2018 - 8%) of its total long-term debt. At December 31, 2019, Hydro One Inc. had the following interest-rate swaps designated as fair value hedges:

•	a $50 million fixed-to-floating interest-rate swap agreement to convert $50 million of the $350 million MTN Series 33 notes maturing April 30, 2020 into three-month variable rate debt; and
•	a $300 million fixed-to-floating interest-rate swap agreement to convert the $300 million MTN Series 39 notes maturing June 25, 2021 into three-month variable rate debt.
---	---

Cash Flow Hedges

At December 31, 2019, Hydro One Inc. had a total of $800 million in 3-year pay-fixed, receive-floating interest-rate swap agreements designated as cash flow hedges. These cash flow hedges are intended to offset the variability of interest rates on the issuances of short-term commercial paper between January 9, 2020 and March 9, 2023.

At December 31, 2019 and 2018, the Company had no interest-rate swaps classified as undesignated contracts.

In October 2017, the Company entered into a Foreign-Exchange Contract to convert $1,400 million Canadian to US dollars at an initial forward rate of 1.27486 Canadian per 1.00 US dollars, and a range up to 1.28735 Canadian per 1.00 US dollars based on the settlement date. The Foreign-Exchange Contract was contingent on the Company closing the proposed Merger (see Note 4 - Business Combinations) and was intended to mitigate the foreign currency risk related to the portion of the Merger purchase price financed with the issuance of Convertible Debentures. This contract was an economic hedge and did not qualify for hedge accounting. It has been accounted for as an undesignated contract with changes in fair value being recorded in earnings as they occurred. As a result of the termination of the Merger agreement (see Note 4 - Business Combinations) in January 2019, the Foreign-Exchange Contract was terminated and previously recorded unrealized gains of $22 million were reversed in financing charges. No payment was due or payable by Hydro One related to the Foreign-Exchange Contract.

^1^ Derivative assets are included in other current assets on the consolidated balance sheets.

^2^ Derivative liabilities are included in other long-term liabilities on the consolidated balance sheets.

The fair value of the hedged portion of the long-term debt is primarily based on the present value of future cash flows using a swap yield curve to determine the assumption for interest rates. The fair value of the unhedged portion of the long-term debt is based on unadjusted period-end market prices for the same or similar debt of the same remaining maturities.

There were no transfers between any of the fair value levels during the years ended December 31, 2019 or 2018.

Changes in the Fair Value of Financial Instruments Classified in Level 3

The following table summarizes the changes in fair value of financial instruments classified in Level 3 for the years ended December 31, 2019 and 2018.

Risk Management

Exposure to market risk, credit risk and liquidity risk arises in the normal course of the Company’s business.

Market Risk

Market risk refers primarily to the risk of loss which results from changes in costs, foreign exchange rates and interest rates. The Company is exposed to fluctuations in interest rates, as its regulated return on equity is derived using a formulaic approach that takes anticipated interest rates into account. The Company is not currently exposed to material commodity price risk or material foreign exchange risk.

The Company uses a combination of fixed and variable-rate debt to manage the mix of its debt portfolio. The Company also uses derivative financial instruments to manage interest-rate risk. The Company may utilize interest-rate swaps designated as fair value hedges as a means to manage its interest rate exposure to achieve a lower cost of debt. The Company may also utilize interest-rate derivative instruments, such as cash flow hedges, to manage its exposure to short-term interest rates or to lock in interest-rate levels in anticipation of future financing.

A hypothetical 100 basis points increase in interest rates associated with variable-rate debt would not have resulted in a significant decrease in Hydro One’s net income for the years ended December 31, 2019 and 2018.

HYDRO ONE LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

For the years ended December 31, 2019 and 2018

For derivative instruments that are designated and qualify as fair value hedges, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in the Consolidated Statements of Operations and Comprehensive Income. The net unrealized loss (gain) on the hedged debt and the related interest-rate swaps for the years ended December 31, 2019 and 2018 were not material.

For derivative instruments that are designated and qualify as cash flow hedges, the unrealized gain or loss, net of tax, on the derivative instrument is recorded as OCI and is reclassified to results of operations in the same period during which the hedged transaction affects results of operations. The unrealized gain, net of tax, on the cash flow hedges for the year ended December 31, 2019 recorded in OCI was $2 million (2018 - $nil), resulting in an AOCI balance of $2 million related to cash flow hedges at December 31, 2019 (2018 - $nil). No amounts were reclassified to results of operations during 2019 or 2018. The Company estimates that the amount of AOCI, net of tax, related to cash flow hedges to be reclassified to results of operations in the next 12 months is not significant. Actual amounts reclassified to results of operations depend on the market risk in effect until the derivative contracts mature. For all forecasted transactions, the maximum term over which the Company is hedging exposures to the variability of cash flows is approximately three years.

Credit Risk

Financial assets create a risk that a counterparty will fail to discharge an obligation, causing a financial loss. At December 31, 2019 and 2018, there were no significant concentrations of credit risk with respect to any class of financial assets. The Company’s revenue is earned from a broad base of customers. As a result, Hydro One did not earn a material amount of revenue from any single customer. At December 31, 2019 and 2018, there was no material accounts receivable balance due from any single customer.

At December 31, 2019, the Company’s allowance for doubtful accounts was $22 million (2018 - $21 million). The allowance for doubtful accounts reflects the Company's current lifetime expected credit losses for all accounts receivable balances, which are based on historical overdue balances, customer payments and write-offs. At December 31, 2019, approximately 5% (2018 - 5%) of the Company’s net accounts receivable were outstanding for more than 60 days.

Hydro One manages its counterparty credit risk through various techniques including: entering into transactions with highly rated counterparties; limiting total exposure levels with individual counterparties; entering into master agreements which enable net settlement and the contractual right of offset; and monitoring the financial condition of counterparties. The Company monitors current credit exposure to counterparties on both an individual and an aggregate basis. The Company’s credit risk for accounts receivable is limited to the carrying amounts on the Consolidated Balance Sheets.

Derivative financial instruments result in exposure to credit risk since there is a risk of counterparty default. The credit exposure of derivative contracts, before collateral, is represented by the fair value of contracts at the reporting date. At December 31, 2019 and 2018, the counterparty credit risk exposure on the fair value of these interest-rate swap contracts was not material. At December 31, 2019, Hydro One’s credit exposure for all derivative instruments, and applicable payables and receivables, had a credit rating of investment grade, with three financial institutions as the counterparties.

Liquidity Risk

Liquidity risk refers to the Company’s ability to meet its financial obligations as they come due. Hydro One meets its short-term operating liquidity requirements using cash and cash equivalents on hand, funds from operations, the issuance of commercial paper, and the Operating Credit Facilities. The short-term liquidity under the Commercial Paper Program, Operating Credit Facilities, and anticipated levels of funds from operations are expected to be sufficient to fund normal operating requirements.

On June 18, 2018, Hydro One filed a short form base shelf prospectus (Universal Base Shelf Prospectus) with securities regulatory authorities in Canada. The Universal Base Shelf Prospectus allows Hydro One to offer, from time to time in one or more public offerings, up to $4.0 billion of debt, equity or other securities, or any combination thereof, during the 25-month period ending on July 18, 2020. On November 23, 2018, HOHL filed a short form base shelf prospectus (US Debt Shelf Prospectus) with securities regulatory authorities in Canada and the US. The US Debt Shelf Prospectus allows HOHL to offer, from time to time in one or more public offerings, up to US$3.0 billion of debt securities, unconditionally guaranteed by Hydro One, during the 25-month period ending on December 23, 2020. At December 31, 2019, no securities have been issued under the Universal Base Shelf Prospectus or the US Debt Shelf Prospectus.

19.	CAPITAL MANAGEMENT

The Company’s objectives with respect to its capital structure are to maintain effective access to capital on a long-term basis at reasonable rates, and to deliver appropriate financial returns. In order to ensure ongoing access to capital, the Company targets to maintain strong credit quality. At December 31, 2019 and 2018, the Company’s capital structure was as follows:

December 31 (millions of dollars)	2019		2018
Long-term debt payable within one year	653		731
Short-term notes payable	1,143		1,252
Less: cash and cash equivalents	(30	)	(483	)
	1,766		1,500
Long-term debt	10,822		9,978
Convertible debentures	—		489
Preferred shares	418		418
Common shares	5,661		5,643
Retained earnings	3,667		3,459
Total capital	22,334		21,487

Hydro One Inc. and HOSSM have customary covenants typically associated with long-term debt. Long-term debt and credit facility covenants limit permissible debt to 75% of its total capitalization, limit the ability to sell assets and impose a negative pledge provision, subject to customary exceptions. At December 31, 2019, the Company was in compliance with all financial covenants and limitations associated with the outstanding borrowings and credit facilities.

20. PENSION AND POST-RETIREMENT AND POST-EMPLOYMENT BENEFITS

Hydro One has a defined benefit pension plan (Pension Plan), a DC Plan, a supplemental pension plan (Supplemental Plan), and post-retirement and post-employment benefit plans.

DC Plan

Hydro One established a DC Plan effective January 1, 2016. The DC Plan covers eligible management employees hired on or after January 1, 2016, as well as management employees hired before January 1, 2016 who were not eligible or had not irrevocably elected to join the Pension Plan as of September 30, 2015. Members of the DC Plan have an option to contribute 4%, 5% or 6% of their pensionable earnings, with matching contributions by Hydro One up to an annual contribution limit. There is also a Supplemental DC Plan that provides members of the DC Plan with employer contributions beyond the limitations imposed by the Income Tax Act (Canada) in the form of credits to a notional account. Hydro One contributions to the DC Plan for the year ended December 31, 2019 were $1 million (2018 - $1 million).

Pension Plan, Supplemental Plan, and Post-Retirement and Post-Employment Plans

The Pension Plan is a defined benefit contributory plan which covers eligible regular employees of Hydro One and its subsidiaries. The Pension Plan provides benefits based on highest three-year average pensionable earnings. For management employees who commenced employment on or after January 1, 2004, and for the Society of United Professionals (Society)-represented staff hired after November 17, 2005, benefits are based on highest five-year average pensionable earnings. After retirement, pensions are indexed to inflation. Membership in the Pension Plan was closed to management employees who were not eligible or had not irrevocably elected to join the Pension Plan as of September 30, 2015. These employees are eligible to join the DC Plan.

Company and employee contributions to the Pension Plan are based on actuarial reports, including valuations performed at least every three years, and actual or projected levels of pensionable earnings, as applicable. The most recent actuarial valuation was performed effective December 31, 2018 and filed on September 30, 2019. The next actuarial valuation will be performed no later than effective December 31, 2021. Total annual cash Pension Plan employer contributions for 2019 were $61 million (2018 - $75 million). Estimated annual Pension Plan employer contributions for the years 2020, 2021, 2022, 2023 and 2024 are approximately $66 million, $65 million, $64 million, $64 million, and $64 million, respectively.

The Supplemental Plan provides members of the Pension Plan with benefits that would have been earned and payable under the Pension Plan beyond the limitations imposed by the Income Tax Act (Canada). The Supplemental Plan obligation is included with other post-retirement and post-employment benefit obligations on the Consolidated Balance Sheets.

Hydro One recognizes the overfunded or underfunded status of the Pension Plan, and post-retirement and post-employment benefit plans (Plans) as an asset or liability on its Consolidated Balance Sheets, with offsetting regulatory assets and liabilities as appropriate. The underfunded benefit obligations for the Plans, in the absence of regulatory accounting, would be recognized in AOCI. The impact of changes in assumptions used to measure pension and post-retirement benefit obligations is generally recognized over the expected average remaining service period of the employees and using the corridor approach for the post-retirement benefit

^2^ Includes $nil (2018 - $7 million) relating to HOSSM post-employment benefit plans. Effective January 1, 2019, liabilities associated with the HOSSM post-employment benefit plans were transferred to the Hydro One post-employment benefit plans.

The funded or unfunded status of the Plans refers to the difference between the fair value of plan assets and the PBO for the Plans. The funded/unfunded status changes over time due to several factors, including contribution levels, assumed discount rates and actual returns on plan assets.

The following table provides the PBO, accumulated benefit obligation (ABO) and fair value of plan assets for the Pension Plan:

December 31 (millions of dollars)	2019	2018

During the year ended December 31, 2019, post-retirement and post-employment costs of $123 million (2018 - $121 million) were attributed to labour, of which $50 million (2018 - $52 million) was charged to operations, $39 million (2018 - $41 million) was recorded as regulatory assets, and $34 million (2018 - $28 million) was capitalized as part of the cost of property, plant and equipment and intangible assets.

Assumptions

The measurement of the obligations of the Plans and the costs of providing benefits under the Plans involves various factors, including the development of valuation assumptions and accounting policy elections. When developing the required assumptions, the Company considers historical information as well as future expectations. The measurement of benefit obligations and costs is impacted by several assumptions including the discount rate applied to benefit obligations, the long-term expected rate of return on plan assets, Hydro One’s expected level of contributions to the Plans, the incidence of mortality, the expected remaining service period of plan participants, the level of compensation and rate of compensation increases, employee age, length of service, and the anticipated rate of increase of health care costs, among other factors. The impact of changes in assumptions used to measure the obligations of the Plans is generally recognized over the expected average remaining service period of the plan participants. In selecting the expected rate of return on plan assets, Hydro One considers historical economic indicators that impact asset returns, as well as expectations regarding future long-term capital market performance, weighted by target asset class allocations. In general, equity securities, real estate and private equity investments are forecasted to have higher returns than fixed-income securities.

The following weighted average assumptions were used to determine the benefit obligations at December 31, 2019 and 2018:

	Pension Benefits				Post-Retirement and<br><br>Post-Employment Benefits
Year ended December 31	2019		2018		2019		2018

The following weighted average assumptions were used to determine the net periodic benefit costs for the years ended December 31, 2019 and 2018. Assumptions used to determine current year-end benefit obligations are the assumptions used to estimate the subsequent year’s net periodic benefit costs.

Year ended December 31	2019		2018
Pension Benefits:
Weighted average expected rate of return on plan assets	6.50	%	6.50	%
Weighted average discount rate	3.90	%	3.40	%

Post-Retirement and Post-Employment Benefits:
Weighted average discount rate	4.00	%	3.40	%
Rate of compensation scale escalation (long-term)	2.50	%	2.50	%
Rate of cost of living increase	2.00	%	2.00	%
Average remaining service life of employees (years)	15.5		15.5
Rate of increase in health care cost trends^1^	4.04	%	4.04	%

^1^5.19% per annum in 2019, grading down to 4.04% per annum in and after 2031 (2018 -^^5.26% per annum in 2018, grading down to 4.04% per annum in and after 2031)

The discount rate used to determine the current year pension obligation and the subsequent year’s net periodic benefit costs is based on a yield curve approach. Under the yield curve approach, expected future benefit payments for each plan are discounted by a rate on a third-party bond yield curve corresponding to each duration. The yield curve is based on “AA” long-term corporate bonds. A single discount rate is calculated that would yield the same present value as the sum of the discounted cash flows.

The effect of a 1% change in health care cost trends on the PBO for the post-retirement and post-employment benefits at December 31, 2019 and 2018 is as follows:

December 31 (millions of dollars)	2019		2018
Projected benefit obligation:
Effect of a 1% increase in health care cost trends	281		230
Effect of a 1% decrease in health care cost trends	(213	)	(175	)

The effect of a 1% change in health care cost trends on the service cost and interest cost for the post-retirement and post-employment benefits for the years ended December 31, 2019 and 2018 is as follows:

Year ended December 31 (millions of dollars)	2019		2018
Service cost and interest cost:
Effect of a 1% increase in health care cost trends	21		23
Effect of a 1% decrease in health care cost trends	(16	)	(16	)

The following approximate life expectancies were used in the mortality assumptions to determine the PBO for the pension and post-retirement and post-employment plans at December 31, 2019 and 2018:

December 31	2019	2018
Life expectancy at age 65 for a member currently at:	(years)	(years)
Age 65 - male	22	22
Age 65 - female	25	25
Age 45 - male	23	23
Age 45 - female	26	25

Estimated Future Benefit Payments

At December 31, 2019, estimated future benefit payments to the participants of the Plans were:

Pension Plan Assets

Investment Strategy

On a regular basis, Hydro One evaluates its investment strategy to ensure that Pension Plan assets will be sufficient to pay Pension Plan benefits when due. As part of this ongoing evaluation, Hydro One may make changes to its targeted asset allocation and investment strategy. The Pension Plan is managed at a net asset level. The main objective of the Pension Plan is to sustain a certain level of net assets in order to meet the pension obligations of the Company. The Pension Plan fulfils its primary objective by adhering to specific investment policies outlined in its Statement of Investment Policies and Procedures (SIPP), which is reviewed and approved by the Human Resource Committee of Hydro One’s Board of Directors. The Company manages net assets by engaging knowledgeable external investment managers who are charged with the responsibility of investing existing funds and new funds (current year’s employee and employer contributions) in accordance with the approved SIPP. The performance of the managers is monitored through a governance structure. Increases in net assets are a direct result of investment income generated by investments held by the Pension Plan and contributions to the Pension Plan by eligible employees and by the Company. The main use of net assets is for benefit payments to eligible Pension Plan members.

Pension Plan Asset Mix

At December 31, 2019, the Pension Plan target asset allocations and weighted average asset allocations were as follows:

	Target Allocation (%)	Pension Plan Assets (%)
Equity securities	45	52
Debt securities	35	35
Real Estate and Infrastructure	20	13
	100	100

At December 31, 2019, the Pension Plan held $21 million (2018 - $18 million) Hydro One corporate bonds and $504 million (2018 - $546 million) of debt securities of the Province.

Concentrations of Credit Risk

Hydro One evaluated its Pension Plan’s asset portfolio for the existence of significant concentrations of credit risk as at December 31, 2019 and 2018. Concentrations that were evaluated include, but are not limited to, investment concentrations in a single entity, concentrations in a type of industry, and concentrations in individual funds. At December 31, 2019 and 2018, there were no significant concentrations (defined as greater than 10% of plan assets) of risk in the Pension Plan’s assets.

The Pension Plan's Statement of Investment Beliefs and Guidelines provides guidelines and restrictions for eligible investments taking into account credit ratings, maximum investment exposure and other controls in order to limit the impact of this risk. The Pension Plan manages its counterparty credit risk with respect to bonds by investing in investment-grade and government bonds and with respect to derivative instruments by transacting only with highly rated financial institutions, and also by ensuring that exposure is diversified across counterparties. The risk of default on transactions in listed securities is considered minimal, as the trade will fail if either party to the transaction does not meet its obligation.

Fair Value Measurements

The following tables present the Pension Plan assets and liabilities measured and recorded at fair value on a recurring basis and their level within the fair value hierarchy at December 31, 2019 and 2018:

Changes in the Fair Value of Financial Instruments Classified in Level 3

The following table summarizes the changes in fair value of financial instruments classified in Level 3 for the years ended December 31, 2019 and 2018. The Pension Plan classifies financial instruments as Level 3 when the fair value is measured based on at least one significant input that is not observable in the markets or due to lack of liquidity in certain markets. The gains and losses presented in the table below could, therefore, include changes in fair value based on both observable and unobservable inputs. The Level 3 financial instruments are comprised of pooled funds whose valuations are provided by the investment managers. Sensitivity analysis is not provided as the underlying assumptions used by the investment managers are not available.

Year ended December 31 (millions of dollars)	2019		2018
Fair value, beginning of year	651		549
Realized and unrealized gains (losses)	(4	)	59
Purchases	463		90
Sales and disbursements	(31	)	(47	)
Fair value, end of year	1,079		651

There were no significant transfers between any of the fair value levels during the years ended December 31, 2019 and 2018.

Valuation Techniques Used to Determine Fair Value

Pooled funds mainly consist of private equity, real estate and infrastructure investments. Private equity investments represent private equity funds that invest in operating companies that are not publicly traded on a stock exchange. Investment strategies in private equity include limited partnerships in businesses that are characterized by high internal growth and operational efficiencies, venture capital, leveraged buyouts and special situations such as distressed investments. Real estate and infrastructure investments represent funds that invest in real assets which are not publicly traded on a stock exchange. Investment strategies in real estate include limited partnerships that seek to generate a total return through income and capital growth by investing primarily in global and Canadian limited partnerships. Investment strategies in infrastructure include limited partnerships in core infrastructure assets focusing on assets that generate stable, long-term cash flows and deliver incremental returns relative to conventional fixed-income investments. Private equity, real estate and infrastructure valuations are reported by the fund manager and are based on the valuation of the underlying investments which includes inputs such as cost, operating results, discounted future cash flows and market-based comparable data. Since these valuation inputs are not highly observable, private equity and infrastructure investments have been categorized as Level 3 within pooled funds.

Cash equivalents consist of demand cash deposits held with banks and cash held by the investment managers. Cash equivalents are categorized as Level 1.

Short-term securities are valued at cost plus accrued interest, which approximates fair value due to their short-term nature. Short-term securities are categorized as Level 2.

Derivative instruments are used to hedge the Pension Plan’s foreign currency exposure back to Canadian dollars. The notional principal amount of contracts outstanding as at December 31, 2019 was $742 million (2018 - $299 million), the most significant currencies being hedged against the Canadian dollar are the United States dollar, euro, British pound sterling, and Japanese yen. The net realized gain on contracts for the year ended December 31, 2019 was $1 million (2018 - $7 million net realized loss). The terms to maturity of the forward exchange contracts at December 31, 2019 are within three months. The fair value is determined using standard interpolation methodology primarily based on the World Markets exchange rates. Derivative instruments are categorized as Level 2.

Corporate shares are valued based on quoted prices in active markets and are categorized as Level 1. Corporate shares which are valued based on quoted prices in active markets, but held within a pension investment holding company, are categorized as Level 2. Investments denominated in foreign currencies are translated into Canadian currency at year-end rates of exchange.

Bonds and debentures are presented at published closing trade quotations, and are categorized as Level 2.

Less: discounting environmental liabilities to present value	(10	)	(1	)	(11	)
Discounted environmental liabilities	108		57		165

At December 31, 2019, the estimated future environmental expenditures were as follows:

December 31 (millions of dollars)	2019
2020	30
2021	31
2022	29
2023	25
2024	8
Thereafter	25
	148

Hydro One records a liability for the estimated future expenditures for LAR and for the phase-out and destruction of PCB-contaminated mineral oil removed from electrical equipment when it is determined that future environmental remediation expenditures are probable under existing statute or regulation and the amount of the future expenditures can be reasonably estimated.

There are uncertainties in estimating future environmental costs due to potential external events such as changes in legislation or regulations, and advances in remediation technologies. In determining the amounts to be recorded as environmental liabilities, the Company estimates the current cost of completing required work and makes assumptions as to when the future expenditures will actually be incurred, in order to generate future cash flow information. A long-term inflation rate assumption of approximately 2% has been used to express these current cost estimates as estimated future expenditures. Future expenditures have been discounted using factors ranging from approximately 2.0% to 6.3%, depending on the appropriate rate for the period when expenditures are expected to be incurred. All factors used in estimating the Company’s environmental liabilities represent management’s best estimates of the present value of costs required to meet existing legislation or regulations. However, it is reasonably possible that numbers or volumes of contaminated assets, cost estimates to perform work, inflation assumptions and the assumed pattern of annual cash flows may differ significantly from the Company’s current assumptions. In addition, with respect to the PCB environmental liability, the availability of critical resources such as skilled labour and replacement assets and the ability to take maintenance outages in critical facilities may influence the timing of expenditures.

PCBs

The Environment Canada regulations, enacted under the Canadian Environmental Protection Act, 1999, govern the management, storage and disposal of PCBs based on certain criteria, including type of equipment, in-use status, and PCB-contamination thresholds. Under current regulations, Hydro One’s PCBs have to be disposed of by the end of 2025, with the exception of specifically exempted equipment. Contaminated equipment will generally be replaced, or will be decontaminated by removing PCB-contaminated insulating oil and retro filling with replacement oil that contains PCBs in concentrations of less than 2 ppm.

At December 31, 2019, the Company’s best estimate of the total estimated future expenditures to comply with current PCB regulations was $97 million (2018 - $118 million). These expenditures are expected to be incurred over the period from 2020 to 2024. As a result of its annual review of environmental liabilities, the Company recorded a revaluation adjustment in 2019 to decrease the PCB environmental liability by $5 million (2018 - $15 million).

LAR

At December 31, 2019, the Company’s best estimate of the total estimated future expenditures to complete its LAR program was $51 million (2018 - $58 million). These expenditures are expected to be incurred over the period from 2020 to 2044. As a result of its annual review of environmental liabilities, the Company recorded a revaluation adjustment in 2019 to increase the LAR environmental liability by $2 million (2018 - $nil).

22. ASSET RETIREMENT OBLIGATIONS

Hydro One records a liability for the estimated future expenditures for the removal and disposal of asbestos-containing materials installed in some of its facilities. Asset retirement obligations, which represent legal obligations associated with the retirement of certain tangible long-lived assets, are computed as the present value of the projected expenditures for the future retirement of specific assets and are recognized in the period in which the liability is incurred, if a reasonable estimate can be made. If the asset remains in service at the recognition date, the present value of the liability is added to the carrying amount of the associated asset in the period the liability is incurred and this additional carrying amount is depreciated over the remaining life of the asset. If an asset retirement obligation is recorded in respect of an out-of-service asset, the asset retirement cost is charged to results of operations. Subsequent to the initial recognition, the liability is adjusted for any revisions to the estimated future cash flows associated with the asset retirement obligation, which can occur due to a number of factors including, but not limited to, cost escalation, changes in technology applicable to the assets to be retired, changes in legislation or regulations, as well as for accretion of the liability due to the passage of time until the obligation is settled. Depreciation expense is adjusted prospectively for any increases or decreases to the carrying amount of the associated asset.

In determining the amounts to be recorded as asset retirement obligations, the Company estimates the current fair value for completing required work and makes assumptions as to when the future expenditures will actually be incurred, in order to generate future cash flow information. A long-term inflation assumption of approximately 2% has been used to express these current cost estimates as estimated future expenditures. Future expenditures have been discounted using factors ranging from approximately 2.0% to 4.0%, depending on the appropriate rate for the period when expenditures are expected to be incurred. All factors used in estimating the Company’s asset retirement obligations represent management’s best estimates of the cost required to meet existing legislation or regulations. However, it is reasonably possible that numbers or volumes of contaminated assets, cost estimates to perform work, inflation assumptions and the assumed pattern of annual cash flows may differ significantly from the Company’s current assumptions. Asset retirement obligations are reviewed annually or more frequently if significant changes in regulations or other relevant factors occur. Estimate changes are accounted for prospectively. As a result of its annual review of asset retirement obligations, no revaluation adjustment to the asset retirement obligations was recorded in 2019 (2018 - revaluation adjustment was recorded to increase the asset retirement obligations by $1 million).

At December 31, 2019, Hydro One had recorded asset retirement obligations of $10 million (2018 - $10 million), primarily consisting of the estimated future expenditures associated with the removal and disposal of asbestos-containing materials installed in some of its facilities. The amount of interest recorded is nominal.

Preferred Shares

The Company is authorized to issue an unlimited number of preferred shares, issuable in series. At December 31, 2019 and 2018, two series of preferred shares were authorized for issuance: the Series 1 preferred shares and the Series 2 preferred shares. At December 31, 2019 and 2018, the Company had 16,720,000 Series 1 preferred shares and no Series 2 preferred shares issued and outstanding.

Hydro One may from time to time issue preferred shares in one or more series. Prior to issuing shares in a series, the Hydro One Board of Directors is required to fix the number of shares in the series and determine the designation, rights, privileges, restrictions and conditions attaching to that series of preferred shares. Holders of Hydro One’s preferred shares are not entitled to receive notice of, to attend or to vote at any meeting of the shareholders of Hydro One except that votes may be granted to a series of preferred shares when dividends have not been paid on any one or more series as determined by the applicable series provisions. Each series of preferred shares ranks on parity with every other series of preferred shares, and are entitled to a preference over the common shares and any other shares ranking junior to the preferred shares, with respect to dividends and the distribution of assets and return of capital in the event of the liquidation, dissolution or winding up of Hydro One.

For the period commencing from the date of issue of the Series 1 preferred shares and ending on and including November 19, 2020, the holders of Series 1 preferred shares are entitled to receive fixed cumulative preferential dividends of $1.0625 per share per year, if and when declared by the Board of Directors, payable quarterly. The dividend rate will reset on November 20, 2020 and every five years thereafter at a rate equal to the sum of the then five-year Government of Canada bond yield and 3.53%. The Series 1 preferred shares will not be redeemable by Hydro One prior to November 20, 2020, but will be redeemable by Hydro One on November 20, 2020 and on November 20 of every fifth year thereafter at a redemption price equal to $25.00 for each Series 1 preferred share redeemed, plus any accrued or unpaid dividends. The holders of Series 1 preferred shares will have the right, at their option, on November 20, 2020 and on November 20 of every fifth year thereafter, to convert all or any of their Series 1 preferred shares into Series 2 preferred shares on a one-for-one basis, subject to certain restrictions on conversion. At December 31, 2019, no preferred share dividends were in arrears.

The holders of Series 2 preferred shares will be entitled to receive quarterly floating rate cumulative dividends, if and when declared by the Board of Directors, at a rate equal to the sum of the then three-month Government of Canada treasury bill rate and 3.53% as reset quarterly. The Series 2 preferred shares will not be redeemable by Hydro One prior to November 20, 2020, but will be redeemable by Hydro One at a redemption price equal to $25.00 for each Series 2 preferred share redeemed, if redeemed on November 20, 2025 or on November 20 of every fifth year thereafter, or $25.50 for each Series 2 preferred share redeemed, if redeemed on any other date after November 20, 2020, in each case plus any accrued or unpaid dividends. The holders of Series 2 preferred shares will have the right, at their option, on November 20, 2025 and on November 20 of every fifth year thereafter, to convert all or any of their Series 2 preferred shares into Series 1 preferred shares on a one-for-one basis, subject to certain restrictions on conversion.

Share Ownership Restrictions

The Electricity Act imposes share ownership restrictions on securities of Hydro One carrying a voting right (Voting Securities). These restrictions provide that no person or company (or combination of persons or companies acting jointly or in concert) may beneficially own or exercise control or direction over more than 10% of any class or series of Voting Securities, including common shares of the Company (Share Ownership Restrictions). The Share Ownership Restrictions do not apply to Voting Securities held by the Province, nor to an underwriter who holds Voting Securities solely for the purpose of distributing those securities to purchasers who comply with the Share Ownership Restrictions.

26. EARNINGS PER COMMON SHARE

Basic earnings per common share (EPS) is calculated by dividing net income (loss) attributable to common shareholders of Hydro One by the weighted-average number of common shares outstanding.

Diluted EPS is calculated by dividing net income (loss) attributable to common shareholders of Hydro One by the weighted-average number of common shares outstanding adjusted for the effects of potentially dilutive stock-based compensation plans, including the share grant plans and the LTIP, which are calculated using the treasury stock method.

The common shares contingently issuable as a result of the Convertible Debentures are not included in diluted EPS for the year ended December 31, 2019 and 2018, as conditions for closing the Merger were not met. As a result of the termination of the Merger agreement (see Note 4 - Business Combinations), the Convertible Debentures were redeemed on February 8, 2019.

27. STOCK-BASED COMPENSATION

Share Grant Plans

Hydro One has two share grant plans (Share Grant Plans), one for the benefit of certain members of the PWU (PWU Share Grant Plan) and one for the benefit of certain members of the Society (Society Share Grant Plan).

The PWU Share Grant Plan provides for the issuance of common shares of Hydro One from treasury to certain eligible members of the PWU annually, commencing on April 1, 2017 and continuing until the earlier of April 1, 2028 or the date an eligible employee no longer meets the eligibility criteria of the PWU Share Grant Plan. To be eligible, an employee must be a member of the Pension Plan on April 1, 2015, be employed on the date annual share issuance occurs and continue to have under 35 years of service. The requisite service period for the PWU Share Grant Plan began on July 3, 2015, which is the date the share grant plan was ratified by the PWU. The number of common shares issued annually to each eligible employee will be equal to 2.7% of such eligible employee’s salary as at April 1, 2015, divided by $20.50, being the price of the common shares of Hydro One in its Initial Public Offering (IPO). The aggregate number of common shares issuable under the PWU Share Grant Plan shall not exceed 3,981,763 common shares. In 2015, 3,979,062 common shares were granted under the PWU Share Grant Plan.

The Society Share Grant Plan provides for the issuance of common shares of Hydro One from treasury to certain eligible members of The Society annually, commencing on April 1, 2018 and continuing until the earlier of April 1, 2029 or the date an eligible employee no longer meets the eligibility criteria of the Society Share Grant Plan. To be eligible, an employee must be a member of the Pension Plan on September 1, 2015, be employed on the date annual share issuance occurs and continue to have under 35 years of service. Therefore, the requisite service period for the Society Share Grant Plan began on September 1, 2015. The number of common shares issued annually to each eligible employee will be equal to 2.0% of such eligible employee’s salary as at September 1, 2015, divided by $20.50, being the price of the common shares of Hydro One in its IPO. The aggregate number of common shares issuable

under the Society Share Grant Plan shall not exceed 1,434,686 common shares. In 2015, 1,433,292 common shares were granted under the Society Share Grant Plan.

The fair value of the Hydro One 2015 share grants of $111 million was estimated based on the grant date share price of $20.50 and is recognized using the graded-vesting attribution method as the share grant plans have both a performance condition and a service condition. In 2019, 462,942 common shares (2018 - 481,460) were issued under the Share Grant Plans. Total share-based compensation recognized during 2019 was $9 million (2018 - $12 million) and was recorded as a regulatory asset.

A summary of share grant activity under the Share Grant Plans during the years ended December 31, 2019 and 2018 is presented below:

Directors' DSU Plan

Under the Directors’ DSU Plan, directors can elect to receive credit for their annual cash retainer in a notional account of DSUs in lieu of cash. Hydro One’s Board of Directors may also determine from time to time that special circumstances exist that would reasonably justify the grant of DSUs to a director as compensation in addition to any regular retainer or fee to which the director is entitled. Each DSU represents a unit with an underlying value equivalent to the value of one common share of the Company and is entitled to accrue common share dividend equivalents in the form of additional DSUs at the time dividends are paid, subsequent to declaration by Hydro One’s Board of Directors.

A summary of DSU awards activity under the Directors' DSU Plan during the years ended December 31, 2019 and 2018 is presented below:

For the year ended December 31, 2019, an expense of $1 million (2018 - $1 million) was recognized in earnings with respect to the Directors' DSU Plan. At December 31, 2019, a liability of $1 million (2018 - $1 million) related to Directors' DSUs has been recorded at the December 31, 2019 closing price of the Company's common shares of $25.08. This liability is included in long-term accounts payable and other liabilities on the Consolidated Balance Sheets.

Management DSU Plan

Under the Management DSU Plan, eligible executive employees can elect to receive a specified proportion of their annual short-term incentive in a notional account of DSUs in lieu of cash. Each DSU represents a unit with an underlying value equivalent to the value of one common share of the Company and is entitled to accrue common share dividend equivalents in the form of additional DSUs at the time dividends are paid, subsequent to declaration by Hydro One’s Board of Directors.

Employee Share Ownership Plan

In 2015, Hydro One established Employee Share Ownership Plans (ESOP) for certain eligible management and non-represented employees (Management ESOP) and for certain eligible Society-represented staff (Society ESOP). Under the Management ESOP, the eligible management and non-represented employees may contribute between 1% and 6% of their base salary towards purchasing common shares of Hydro One. The Company matches 50% of their contributions, up to a maximum Company contribution of $25,000 per calendar year.

LTIP

Effective August 31, 2015, the Board of Directors of Hydro One adopted an LTIP. Under the LTIP, long-term incentives are granted to certain executive and management employees of Hydro One and its subsidiaries, and all equity-based awards will be settled in newly issued shares of Hydro One from treasury, consistent with the provisions of the plan which also permit the participants to surrender a portion of their awards to satisfy related withholding taxes requirements. The aggregate number of shares issuable under the LTIP shall not exceed 11,900,000 shares of Hydro One.

The LTIP provides flexibility to award a range of vehicles, including Performance Share Units (PSUs), Restricted Share Units (RSUs), stock options, share appreciation rights, restricted shares, DSUs, and other share-based awards. The mix of vehicles is intended to vary by role to recognize the level of executive accountability for overall business performance.

Amounts recognized in 2019 were affected by the reversal in the third quarter of 2019 of approximately $3 million of previously recognized compensation expense to reflect forfeitures of PSUs and RSUs in the third quarter of 2019. The expense recognized in 2018 included $5 million related to previously awarded PSUs and RSUs to the Company's former President and Chief Executive Officer for which costs had not previously been recognized.

Stock Options

The Company is authorized to grant stock options under its LTIP to certain eligible employees. No stock options were granted in 2019 (2018 - 1,450,880 stock options were granted). The stock options granted are exercisable for a period not to exceed seven years from the date of grant.

B2M LP

On December 16, 2014, transmission assets totalling $526 million were transferred from Hydro One Networks to B2M LP. This was financed by 60% debt ($316 million) and 40% equity ($210 million). On December 17, 2014, the SON acquired a 34.2% equity interest in B2M LP for consideration of $72 million, representing the fair value of the equity interest acquired. The SON’s initial investment in B2M LP consists of $50 million of Class A units and $22 million of Class B units.

The Class B units have a mandatory put option which requires that upon the occurrence of an enforcement event (i.e., an event of default such as a debt default by the SON or insolvency event), Hydro One purchase the Class B units of B2M LP for net book value on the redemption date. The noncontrolling interest relating to the Class B units is classified on the Consolidated Balance Sheet as temporary equity because the redemption feature is outside the control of the Company. The balance of the noncontrolling interest is classified within equity.

The following tables show the movements in B2M LP noncontrolling interest during the years ended December 31, 2019 and 2018:

Capital Contributions

Hydro One enters into contracts governed by the OEB Transmission System Code when a transmission customer requests a new or upgraded transmission connection. The customer is required to make a capital contribution to Hydro One based on the shortfall between the present value of the costs of the connection facility and the present value of revenues. The present value of revenues is based on an estimate of load forecast for the period of the contract with Hydro One. Once the connection facility is commissioned, in accordance with the OEB Transmission System Code, Hydro One will periodically reassess the estimated load forecast which will lead to a decrease, or an increase in the capital contributions from the customer. The increase or decrease in capital contributions is recorded directly to property, plant and equipment in service. In 2019, capital contributions from these reassessments totalled $3 million (2018 - $7 million), which represents the difference between the revised load forecast of electricity transmitted compared to the load forecast in the original contract, subject to certain adjustments.

31. CONTINGENCIES

Legal Proceedings

Hydro One is involved in various lawsuits and claims in the normal course of business. In the opinion of management, the outcome of such matters will not have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.

Hydro One Inc., Hydro One Networks, Hydro One Remote Communities, and Norfolk Power Distribution Inc. were defendants in a class action suit commenced in 2015 in which the representative plaintiff was seeking up to $125 million in damages related to allegations of improper billing practices. The plaintiff’s application for leave to appeal the lower court’s refusal to certify the lawsuit as a class action was denied by the Ontario Court of Appeal on March 26, 2019, which means that the lawsuit has effectively ended.

There were four putative class action lawsuits filed by Avista Corporation shareholders in relation to the Merger. The plaintiffs in the four lawsuits were, respectively, Fink, Jenß, Samuel and Sharpenter. All of these class action lawsuits have now been dismissed.

Transfer of Assets

The transfer orders by which the Company acquired certain of Ontario Hydro’s businesses as of April 1, 1999 did not transfer title to some assets located on Reserves (as defined in the Indian Act (Canada)). Currently, the OEFC holds these assets. Under the terms of the transfer orders, the Company is required to manage these assets until it has obtained all consents necessary to complete the transfer of title of these assets to itself. The Company cannot predict the aggregate amount that it may have to pay, either on an annual or one-time basis, to obtain the required consents. In 2019, the Company paid approximately $2 million (2018 - $2 million) in respect of consents obtained. If the Company cannot obtain the required consents, the OEFC will continue to hold these assets for an indefinite period of time. If the Company cannot reach a satisfactory settlement, it may have to relocate these assets to other locations at a cost that could be substantial or, in a limited number of cases, to abandon a line and replace it with diesel-generation facilities. The costs relating to these assets could have a material adverse effect on the Company’s results of operations if the Company is not able to recover them in future rate orders.

---	---

Prudential Support

Purchasers of electricity in Ontario, through the IESO, are required to provide security to mitigate the risk of their default based on their expected activity in the market. The IESO could draw on these guarantees and/or letters of credit if these purchasers fail to make a payment required by a default notice issued by the IESO. The maximum potential payment is the face value of any letters of credit plus the amount of the parental guarantees.

Retirement Compensation Arrangements

Bank letters of credit have been issued to provide security for Hydro One Inc.’s liability under the terms of a trust fund established pursuant to the supplementary pension plan for eligible employees of Hydro One Inc. The supplementary pension plan trustee is required to draw upon these letters of credit if Hydro One Inc. is in default of its obligations under the terms of this plan. Such obligations include the requirement to provide the trustee with an annual actuarial report as well as letters of credit sufficient to secure Hydro One Inc.’s liability under the plan, to pay benefits payable under the plan and to pay the letter of credit fee. The maximum potential payment is the face value of the letters of credit. A bank letter of credit has also been issued to provide security for Hydro One's retirement compensation arrangement trust agreement.

33. SEGMENTED REPORTING

Hydro One has three reportable segments:

•	The Transmission Segment, which comprises the transmission of high voltage electricity across the province, interconnecting more than 70 local distribution companies and certain large directly connected industrial customers throughout the Ontario electricity grid;

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

Other Segment

The telecommunication business is carried out by Hydro One's wholly-owned subsidiary Hydro One Telecom Inc. (Hydro One Telecom). It also offers comprehensive communications and information technology services and solutions (for example, cloud services, managed services and security-based services) that extend beyond Hydro One Telecom's fibre optic network, in a competitive commercial market. Hydro One Telecom is not regulated by the OEB. However, Hydro One Telecom is registered with the Canadian Radio-television and Telecommunications Commission as a non-dominant, facilities-based carrier, providing broadband telecommunications services in Ontario with connections to Montreal, Quebec; Buffalo, New York; and Detroit, Michigan.

Corporate activities include the deferred tax asset which arose on the transition from the provincial payments in lieu of tax regime to the federal tax regime at the time of the Company’s initial public offering in 2015 and reflects the revaluation of the tax basis of Hydro One’s assets to fair market value.

PRIMARY FACTORS AFFECTING RESULTS OF OPERATIONS

Transmission Revenues

Transmission revenues primarily consist of regulated transmission rates approved by the OEB which are charged based on the monthly peak electricity demand across Hydro One’s high-voltage network. Transmission rates are designed to generate revenues necessary to construct, upgrade, extend and support a transmission system with sufficient capacity to accommodate maximum forecasted demand and a regulated return on the Company’s investment. Peak electricity demand is primarily influenced by weather and economic conditions. Transmission revenues also include export revenues associated with transmitting electricity to markets outside of Ontario. Ancillary revenues include revenues associated with providing maintenance services to power generators and from third-party land use.

Distribution Revenues

Distribution revenues primarily consist of regulated distribution rates approved by the OEB, as well as the recovery of purchased power costs. Distribution rates are designed to generate revenues necessary to construct and support the local distribution system with sufficient capacity to accommodate existing and new customer demand and a regulated return on the Company’s investment. Accordingly, distribution revenues are influenced by distribution rates, the cost of purchased power, and the amount of electricity the Company distributes. Distribution revenues also include ancillary distribution service revenues, such as fees related to the joint use of Hydro One’s distribution poles by the telecommunications and cable television industries, as well as miscellaneous revenues such as charges for late payments.

Purchased Power Costs

Purchased power costs are incurred by the distribution business and represent the cost of the electricity purchased by the Company for delivery to customers within Hydro One’s distribution service territory. These costs are comprised of: (i) the wholesale commodity cost of energy; (ii) the Global Adjustment, which is the difference between amounts the IESO pays energy producers for the electricity they produce and the actual fair market value of this electricity; and (iii) the wholesale market service and transmission charges levied by the IESO. Hydro One passes on the cost of electricity that it delivers to its customers, and is therefore not exposed to wholesale electricity commodity price risk.

Operation, Maintenance and Administration Costs

OM&A costs are incurred to support the operation and maintenance of the transmission and distribution systems, and include other costs such as property taxes related to transmission and distribution stations and buildings, and the operation of information technology (IT) systems. Transmission OM&A costs are required to sustain the Company’s high-voltage transmission stations, lines, and rights-of-way, and include preventive and corrective maintenance costs related to power equipment, overhead transmission lines, transmission station sites, and forestry control to maintain safe distances between line spans and trees. Distribution OM&A costs are required to maintain the Company’s low-voltage distribution system to provide safe and reliable electricity to the Company's residential, small business, commercial, and industrial customers across the province. These include costs related to distribution line clearing and forestry control to reduce power outages caused by trees, line maintenance and repair, land assessment and remediation, as well as issuing timely and accurate bills and responding to customer inquiries.

Hydro One manages its costs through ongoing efficiency and productivity initiatives, while continuing to complete planned work programs associated with the development and maintenance of its transmission and distribution networks.

Depreciation, Amortization and Asset Removal Costs

Depreciation and amortization costs relate primarily to depreciation of the Company’s property, plant and equipment, and amortization of certain intangible assets and regulatory assets. Asset removal costs consist of costs incurred to remove property, plant and equipment where no asset retirement obligations have been recorded on the balance sheet.

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

Financing Charges

Financing charges relate to the Company’s financing activities, and include interest expense on the Company’s long-term debt and short-term borrowings, as well as gains and losses on interest rate swap agreements, contingent foreign exchange or other similar contracts, net of interest earned on short-term investments. A portion of financing charges incurred by the Company is capitalized to the cost of property, plant and equipment associated with the periods during which such assets are under construction before being placed in-service.

RESULTS OF OPERATIONS

Net Income

Net income attributable to common shareholders for the year ended December 31, 2019 of $778 million is an increase of $867 million or 974.2% from the prior year. Significant influences on earnings included:

•	higher revenues, net of purchased power, primarily resulting from:
•	an increase in distribution revenues, net of purchased power, due to the OEB's decision on the 2018 and 2019 distribution rates; partially offset by
---	---
•	lower average monthly Ontario 60-minute peak demand and energy consumption driven by less favourable weather in 2019; and
---	---
•	lower revenues as a result of deferred tax asset sharing mandated by the OEB and deferred tax regulatory adjustment related to accelerated tax depreciation (Accelerated CCA), both of which will flow through to customers and are offset with lower taxes, with no impact on regulated return-on-equity (ROE);
---	---
•	higher OM&A costs primarily resulting from the payment of the termination fee related to the terminated acquisition of Avista Corporation (Merger) and higher vegetation management coverage; partially offset by lower corporate support costs, insurance proceeds received in 2019, and lower spend on station and lines maintenance programs;
---	---
•	higher financing charges primarily resulting from an increase in interest expense on long-term debt; and increased Merger-related financing charges; and
---	---
•	lower income tax expense as a result of the prior year charge to deferred tax expense related to the impairment of Hydro One's deferred income tax regulatory asset, as well as the deferred tax asset sharing and Accelerated CCA, both of which will flow through to customers and are offset with lower revenues, with no impact on regulated ROE.
---	---

EPS and Adjusted EPS

EPS was $1.30 in 2019, compared to a loss per share of $0.15 in 2018. The increase in EPS was driven by higher earnings in 2019, as discussed above. Adjusted EPS, which adjusts for income and costs related to the Merger, including gains and losses on the deal-contingent foreign-exchange forward contract (Foreign-Exchange Contract), as well as the impacts related to the DTA Decision was $1.54 in 2019, compared to $1.35 in 2018. The increase in Adjusted EPS was driven by higher net income in 2019, as discussed above, but excluding the impacts of the Merger and the DTA Decision. See section "Non-GAAP Measures" for description and reconciliation of Adjusted EPS.

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

Transmission Revenues

Transmission revenues decreased by 2.0% in 2019 primarily due to the following:

•	lower average monthly Ontario 60-minute peak demand driven by less favourable weather in 2019; and
•	deferred tax regulatory adjustment related to Accelerated CCA; partially offset by
---	---
•	the 2018 impact of the OEB decision in respect of the deferred tax asset;
---	---
•	increased OEB-approved transmission rates for 2019; and
---	---
•	revenue related to NRLP assets placed in-service in late August 2019.
---	---

Distribution Revenues, Net of Purchased Power

Distribution revenues, net of purchased power, increased by 10.1% in 2019 primarily due to the following:

•	the OEB's decision on the 2018 and 2019 distribution rates; partially offset by
•	deferred tax asset sharing mandated by the OEB and deferred tax regulatory adjustment related to Accelerated CCA; and
---	---
•	deferred regulatory adjustment related to Earnings Sharing Mechanism in 2019.
---	---

OM&A Costs

Year ended December 31 (millions of dollars)	2019	2018	Change
Transmission	355	409	(13.2	%)
Distribution	610	602	1.3	%
Other	216	94	129.8	%
	1,181	1,105	6.9	%

Transmission OM&A Costs

The decrease of 13.2% in transmission OM&A costs for the year ended December 31, 2019 was primarily due to:

•	higher insurance proceeds received in 2019;
•	lower spend on station and lines maintenance programs;
---	---
•	lower project write-offs in 2019;
---	---
•	lower volume of work on transmission vegetation management coverage;
---	---
•	lower property taxes due to a reassessment of municipal property taxes; and
---	---
•	lower corporate support costs; partially offset by
---	---
•	higher spend related to IT projects as a result of the implementation of new tools to support ongoing operations.
---	---

Distribution OM&A Costs

The increase of 1.3% in distribution OM&A costs for the year ended December 31, 2019 was primarily due to:

•	higher volume of work on distribution vegetation management coverage;
•	higher emergency power restoration costs due to a higher volume of non-storm related emergency calls; and
---	---
•	higher spend related to IT projects; partially offset by
---	---
•	lower corporate support costs;
---	---
•	lower costs resulting from the repatriation of the Call Centre;
---	---
•	mutual storm assistance costs in the first quarter of 2018 (net income neutral); and
---	---
•	lower project write-offs in 2019.
---	---

Other OM&A Costs

The increase in other OM&A costs for the year ended December 31, 2019 was primarily due to the payment of the Merger termination fee and higher project write-offs related to the regulatory decision on the Lake Superior Link project, partially offset by lower corporate support costs.

Depreciation, Amortization and Asset Removal Costs

The increase of $41 million or 4.9% in depreciation, amortization and asset removal costs in 2019 was mainly due to the growth in capital assets as the Company continues to place new assets in-service, consistent with its ongoing capital investment program.

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

Financing Charges

The increase of $55 million or 12.0% in financing charges for the year ended December 31, 2019 was primarily due to:

•

an increase in interest expense on long-term debt and short-term notes payable, primarily driven by higher balances outstanding in 2019; and

•

higher Merger-related financing charges, including the write-off of deferred financing costs related to the convertible debentures redeemed in February 2019, the reversal of previously recorded unrealized gains on the Foreign-Exchange Contract, and unrealized gain on the Foreign-Exchange Contract recorded in 2018, partially offset by a decrease in interest expense related to the convertible debentures.

---

Income Tax Expense

Income tax recovery was $6 million for the year ended December 31, 2019, compared to an income tax expense of $915 million in 2018. The Company realized an effective tax rate (ETR) of approximately (0.8%) in 2019, compared to approximately 107.6% in 2018.

As prescribed by the regulators, the Company recovers income taxes and is required to accrue its tax expense based on the tax liability determined without accounting for temporary differences recoverable from or refundable to customers in the future.

The decrease in income tax expense for the year ended December 31, 2019 was primarily attributable to the following:

•	the prior year charge to deferred tax expense related to the impairment of Hydro One's deferred income tax regulatory asset;
•	deferred tax asset sharing mandated by the OEB; and
---	---
•	Accelerated CCA resulting from the enactment of certain 2019 federal and Ontario budget measures in the second quarter of 2019; partially offset by
---	---
•	tax recovery on the termination fee and financing charges related to the Merger.
---	---

Common Share Dividends

In 2019, the Company declared and paid cash dividends to common shareholders as follows:

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

Net Income (Loss) - 2018 compared to 2017

Net loss attributable to common shareholders for the year ended December 31, 2018 of $89 million represents a $747 million or 113.5% reduction in earnings from the prior year. Significant influences on earnings included:

•	higher income tax expense primarily attributable to a one-time charge to deferred tax expense in 2018 related to the impairment of Hydro One's deferred income tax regulatory asset;
•	higher OM&A costs primarily resulting from higher vegetation management costs, property taxes, project write-offs, and demand maintenance work on power equipment and overhead lines; partially offset by savings related to the renewed IT contract and lower costs related to the Merger; and
---	---
•	higher Merger-related financing charges, including an increase in interest expense incurred on the convertible debentures, partially offset by revaluation of the Foreign-Exchange Contract; partially offset by
---	---
•	an increase in transmission and distribution revenues primarily due to higher energy consumption resulting from favourable weather; and higher transmission revenues driven by increased OEB-approved transmission rates.
---	---

EPS and Adjusted EPS - 2018 compared to 2017

EPS was a loss of $0.15 in 2018, compared to earnings of $1.11 in 2017. The decrease in EPS was driven by lower earnings in 2018, as discussed above. Adjusted EPS was $1.35 in 2018, compared to $1.17 in 2017. The increase in Adjusted EPS was driven by net income impacts discussed above, but excluding the impacts of the Merger and the DTA Decision.

Variations in revenues and net income over the quarters are primarily due to the impact of seasonal weather conditions on customer demand and market pricing, as well as timing of regulatory decisions.

CAPITAL INVESTMENTS

The Company makes capital investments to maintain the safety, reliability and integrity of its transmission and distribution system assets and to provide for the ongoing growth and modernization required to meet the expanding and evolving needs of its customers and the electricity market. This is achieved through a combination of sustaining capital investments, which are required to support the continued operation of Hydro One’s existing assets, and development capital investments, which involve both additions to existing assets and large-scale projects such as new transmission lines and transmission stations.

^1^ The Niagara Reinforcement Project was placed in-service in August 2019. Total costs include $119 million for the construction of a new 230 kV transmission line (Niagara Line), as well as $16 million for costs relating to other assets, including stations. In September 2019, the Niagara Line assets were transferred from Hydro One Networks to NRLP. See section Regulation - NRLP for additional information.

^2^ The majority of the East-West Tie Station Expansion project is expected to be placed in-service in 2021, enabling the connection and energization of the new East-West Tie transmission line. Additional work to complete the upgrades is expected to be placed in-service in 2022.

^3^ The in-service date and the costs of the Waasigan Transmission Line project (formerly known as Northwest Bulk Transmission Line Development project) relate to the development phase.

^4^ The Leamington Area Transmission Reinforcement project consists of the construction of a new double-circuit line between Chatham and Leamington and associated transmission stations and connections. The project is currently in the development stage. The anticipated in-service dates for the line and stations are between 2020 and 2026, and the total estimated cost is in the range of $290 million to $325 million, with approximately $249 million of the total estimated cost included in the projected capital investments tables in section "Future Capital Investments" below.

^5^ Approximately $76 million of the total estimated cost is included in the projected capital investments tables in section "Future Capital Investments" below.

Future Capital Investments

Following is a summary of estimated capital investments by Hydro One over the years 2020 to 2024. The Company’s estimates are based on management’s expectations of the amount of capital expenditures that will be required to provide transmission and distribution services that are efficient, reliable, and provide value for customers, consistent with the OEB’s Renewed Regulatory Framework.

The 2020 to 2022 distribution capital investments estimates differ from 2018 year end disclosures, representing a decrease to reflect Hydro One’s five-year rate application for 2018-2022 distribution rates. The 2020 to 2022 transmission capital investments and 2023 distribution capital investments estimates are lower than the prior year disclosures as the Company has updated its plan for timing and pacing of future capital investments, as well as reprioritization of work. Changes in other capital investments are due to timing and new planned capital investments by Hydro One Telecom, as well as capital investments by Ontario Charging Network LP (OCN LP), a joint venture limited partnership between a subsidiary of Hydro One and Ontario Power Generation Inc. (OPG). The projections and the timing of the transmission 2020-2024 expenditures and the distribution 2023-2024 expenditures are subject to approval by the OEB.

The following table summarizes Hydro One’s annual projected capital investments for 2020 to 2024, by business segment:

SUMMARY OF SOURCES AND USES OF CASH

Hydro One’s primary sources of cash flows are funds generated from operations, capital market debt issuances and bank credit facilities that are used to satisfy Hydro One’s capital resource requirements, including the Company’s capital expenditures, servicing and repayment of debt, and dividend payments.

Year ended December 31 (millions of dollars)	2019		2018
Cash provided by operating activities	1,614		1,575
Cash provided by (used in) financing activities	(439	)	399
Cash used in investing activities	(1,628	)	(1,516	)
Increase (decrease) in cash and cash equivalents	(453	)	458

Cash provided by operating activities

Cash from operating activities increased by $39 million for the year ended December 31, 2019 compared to 2018. The increase was impacted by various factors, including higher cash earnings in 2019, changes in accrued purchased power costs resulting from higher energy rates and lower generation rebates from the IESO, partially offset by a higher receivable from IESO due to introduction of the new Ontario Electricity Rebate in November 2019, changes in certain regulatory variance and deferral accounts, as well as changes in receivable balances mainly due to higher non-energy revenues in 2019 related to secondary land use.

Cash provided by (used in) financing activities

Sources of cash

•	The Company issued $1,500 million of long-term debt in 2019, compared to $1,400 million issued in 2018.
•	The Company received proceeds of $4,217 million from the issuance of short-term notes in 2019, compared to $4,242 million received in 2018.
---	---

Uses of cash

•	The Company repaid $4,326 million of short-term notes in 2019, compared to $3,916 million repaid in 2018.

---	---
•	The Company redeemed $513 million of convertible debentures in 2019, compared to no convertible debentures redeemed in 2018.
---	---
•	Dividends paid in 2019 were $588 million, consisting of $570 million common share dividends and $18 million of preferred share dividends, compared to dividends of $560 million paid in 2018, consisting of $542 million common share dividends and $18 million of preferred share dividends.
---	---

Cash used in investing activities

Capital expenditures were higher in 2019, primarily due to higher volume and timing of capital investment work.

LIQUIDITY AND FINANCING STRATEGY

Short-term liquidity is provided through FFO, Hydro One Inc.’s commercial paper program, and the Company’s consolidated bank credit facilities. Under the commercial paper program, Hydro One Inc. is authorized to issue up to $2,300 million in short-term notes with a term to maturity of up to 365 days. On March 25, 2019, the maximum number of short-term notes authorized for issuance was increased from $1,500 million to $2,300 million.

At December 31, 2019, Hydro One Inc. had $1,143 million in commercial paper borrowings outstanding, compared to $1,252 million outstanding at December 31, 2018. The interest rates on the commercial paper borrowings outstanding at December 31, 2019 ranged from 1.8% to 1.9%. In addition, the Company has revolving bank credit facilities (Operating Credit Facilities) with total availability of $2,550 million. On June 3, 2019, the maturity dates for the Operating Credit Facilities were extended from November 2021 and June 2022 to June 2024. At December 31, 2019 and 2018, no amounts were drawn on the Operating Credit Facilities. The Company may use these credit facilities for working capital and general corporate purposes. The short-term liquidity under the

10

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

commercial paper program, the Operating Credit Facilities, and anticipated levels of FFO are expected to be sufficient to fund the Company’s normal operating requirements.

On February 1, 2019, Hydro One entered into a credit agreement for a $170 million unsecured demand operating credit facility (Demand Facility) which was used to fund the payment of the Merger termination fee and other Merger-related costs. On June 6, 2019, the $170 million drawn on the Demand Facility was repaid, and the Demand Facility is no longer available.

At December 31, 2019, the Company had long-term debt outstanding in the principal amount of $11,486 million, which included $11,345 million of long-term debt issued by Hydro One Inc. and long-term debt in the principal amount of $141 million issued by HOSSM. The majority of long-term debt issued by Hydro One Inc. has been issued under its Medium Term Note (MTN) Program. The long-term debt consists of notes and debentures that mature between 2020 and 2064, and at December 31, 2019, had a weighted-average term to maturity of approximately 15.7 years and a weighted-average coupon rate of 4.2%. The maximum authorized principal amount of notes issuable under the current MTN Program prospectus filed in March 2018 is $4.0 billion. At December 31, 2019, $1,100 million remained available for issuance until April 2020. A new MTN Program prospectus is expected to be filed in the first half of 2020.

On June 18, 2018, Hydro One filed a short form base shelf prospectus (Universal Base Shelf Prospectus) with securities regulatory authorities in Canada. The Universal Base Shelf Prospectus allows Hydro One to offer, from time to time in one or more public offerings, up to $4.0 billion of debt, equity or other securities, or any combination thereof, during the 25-month period ending on July 18, 2020. On November 23, 2018, Hydro One Holdings Limited (HOHL), an indirect wholly-owned subsidiary of Hydro One, filed a short form base shelf prospectus (US Debt Shelf Prospectus) with securities regulatory authorities in Canada and the US for the purposes of, but not limited to, funding a portion of the cash purchase price of the Merger. The US Debt Shelf Prospectus allows HOHL to offer, from time to time in one or more public offerings, up to US$3.0 billion of debt securities, unconditionally guaranteed by Hydro One, during the 25-month period ending on December 23, 2020. At December 31, 2019, no securities have been issued under the Universal Base Shelf Prospectus or the US Debt Shelf Prospectus.

Acquisition Credit Facilities

In June 2018, for the purpose of bridge financing for the Merger, the Company secured a $1.0 billion non-revolving equity bridge credit facility, and a US$2.6 billion non-revolving debt bridge credit facility (Acquisition Credit Facilities). As a result of the termination of the Merger agreement, in January 2019, the Company cancelled the Acquisition Credit Facilities, with no amounts drawn.

In addition, the Foreign-Exchange Contract entered into in October 2017 that was intended to mitigate the foreign currency risk related to the portion of the Merger purchase price financed by the issuance of convertible debentures was terminated and revalued to $nil, resulting in a loss of $22 million recorded in 2019, compared to an unrealized gain of $25 million recorded in 2018. No amounts were paid or received by Hydro One.

Compliance

At December 31, 2019, the Company was in compliance with all financial covenants and limitations associated with the outstanding borrowings and credit facilities.

Credit Ratings

Various ratings organizations review the Company’s and Hydro One Inc.’s debt ratings from time to time. These ratings organizations may take various actions, positive or negative. The Company cannot predict what actions rating agencies may take in the future. The failure to maintain the Company’s current credit ratings could adversely affect the Company’s financial condition and results of operations, and a downgrade in the Company’s credit ratings could restrict the Company’s ability to access debt capital markets and increase the Company’s cost of debt.

On November 20, 2019, Moody's Investors Service (Moody’s) upgraded Hydro One Inc.'s long-term debt rating to "A3" from "Baa1", and affirmed the short-term rating for commercial paper at "P-2". Moody's maintained the stable outlook on the ratings. The upgrade reflects Moody’s view of an increased probability of extraordinary support from the provincial government due to the Company’s exclusive focus on its businesses in Ontario for at least the next five years.

On November 8, 2019, S&P Global Ratings (S&P) affirmed the Company’s issuer credit rating and Hydro One Inc.’s issuer and issue-level credit ratings and revised its ratings outlook on Hydro One and Hydro One Inc. to stable from negative, based on expectations that Hydro One’s operating environment has stabilized and that the Company will focus on regulated operations in Ontario, without expansion outside Ontario.

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

At December 31, 2019, Hydro One’s corporate credit ratings were as follows:

Rating Agency	Corporate Credit<br><br>Rating
S&P	A-

At December 31, 2019, Hydro One Inc.’s long-term and short-term debt ratings were as follows:

Rating Agency	Short-term Debt<br>Rating	Long-term Debt<br>Rating
DBRS Limited	R-1 (low)	A (high)
Moody's	Prime-2	A3
S&P	A-1 (low)	A-

Hydro One has not obtained a credit rating in respect of any of its securities. An issuer rating from S&P is a forward-looking opinion about an obligor’s overall creditworthiness. This opinion focuses on the obligor’s capacity and willingness to meet its financial commitments as they come due but it does not apply to any specific financial obligation. An obligor with a long-term credit rating of ‘A’ has strong capacity to meet its financial commitments but is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligors in higher-rated categories.

The rating above is not a recommendation to purchase, sell or hold any of Hydro One’s securities and does not comment on the market price or suitability of any of the securities for a particular investor. There can be no assurance that the rating will remain in effect for any given period of time or that the rating will not be revised or withdrawn entirely by S&P at any time in the future. Hydro One has made, and anticipates making, payments to S&P pursuant to agreements entered into with S&P in respect of the rating assigned to Hydro One and expects to make payments to S&P in the future to the extent it obtains a rating specific to any of its securities.

Effect of Interest Rates

The Company is exposed to fluctuations of interest rates as its regulated ROE is derived using a formulaic approach that takes into account changes in benchmark interest rates for Government of Canada debt and the A-rated utility corporate bond yield spread. The Company issues debt from time to time to refinance maturing debt and for general corporate purposes. The Company is therefore exposed to fluctuations in interest rates in relation to such issuances of debt. See section “Risk Management and Risk Factors - Risks Relating to Hydro One’s Business - Market, Financial Instrument and Credit Risk” for more details.

Pension Plan

In 2019, Hydro One made cash contributions of $61 million to its pension plan, compared to cash contributions of $75 million in 2018, and incurred $41 million in net periodic pension benefit costs, compared to $75 million incurred in 2018.

In September 2019, Hydro One filed an actuarial valuation of its pension plan as at December 31, 2018. Hydro One estimates that total Company pension contributions for 2020, 2021, 2022, 2023 and 2024 are approximately $66 million, $65 million, $64 million, $64 million, and $64 million, respectively.

The Company’s pension benefits obligation is impacted by various assumptions and estimates, such as discount rate, rate of return on plan assets, rate of cost of living increase and mortality assumptions. A full discussion of the significant assumptions and estimates can be found in the section “Critical Accounting Estimates - Employee Future Benefits”.

OTHER OBLIGATIONS

Off-Balance Sheet Arrangements

There are no off-balance sheet arrangements that have, or are reasonably likely to have, a material current or future effect on the Company’s financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

REGULATION

The OEB approves both the revenue requirements and the rates charged by Hydro One’s regulated transmission and distribution businesses. The rates are designed to permit the Company’s transmission and distribution businesses to recover the allowed costs and to earn a formula-based annual rate of return on its deemed 40% equity level invested in the regulated businesses. This is done by applying a specified equity risk premium to forecasted interest rates on long-term bonds. In addition, the OEB approves rate riders to allow for the recovery or disposition of specific regulatory deferral and variance accounts over specified time frames.

Electricity Rates Applications

Hydro One Networks - Transmission

On September 28, 2017, the OEB issued its decision and order on Hydro One Networks' 2017 and 2018 transmission rates revenue requirements (Original Decision), with 2017 rates effective January 1, 2017.

In its Original Decision, the OEB concluded that the net deferred tax asset resulting from transition from the payments in lieu of tax regime under the Electricity Act, 1998 (Ontario) to tax payments under the federal and provincial tax regime should not accrue entirely to Hydro One shareholders and that a portion should be shared with ratepayers. On November 9, 2017, the OEB issued a decision and order that calculated the portion of the tax savings that should be shared with ratepayers. The OEB's calculation would result in an impairment of a portion of both Hydro One Networks' transmission and distribution deferred income tax regulatory asset. In October 2017, the Company filed a motion to review and vary (Motion) the Original Decision and filed an appeal with the Ontario Divisional Court (Appeal). In both cases, the Company's position was that the OEB made errors of fact and law in its determination of allocation of the tax savings between the shareholders and ratepayers. On December 19, 2017, the OEB granted a hearing of the merits of the Motion which was held on February 12, 2018. On August 31, 2018, the OEB granted the Motion and returned the portion of the Original Decision relating to the deferred tax asset to an OEB panel for reconsideration.

On March 7, 2019, the OEB issued its reconsideration decision (DTA Decision) and concluded that their Original Decision was reasonable and should be upheld. Also, on March 7, 2019, the OEB issued its decision for Hydro One Networks’ 2018-2022 distribution rates, in which it directed the Company to apply the Original Decision to Hydro One Networks’ distribution rates. As a result, as at December 31, 2018, the Company recognized an impairment charge of Hydro One Networks' distribution deferred income tax regulatory asset of $474 million and Hydro One Networks' transmission deferred income tax regulatory asset of $558 million, an increase in deferred income tax regulatory liability of $81 million, and a decrease in the foregone revenue deferral regulatory asset of $68 million. After recognition of the related $314 million deferred tax asset, the Company recorded an $867 million one-time decrease in net income as a reversal of revenues of $68 million, and charge to deferred tax expense of $799 million, which is expected to result in an annual decrease to FFO in the range of $50 million to $60 million in the near term, and this range will decline over time. Notwithstanding the recognition of the effects of the DTA Decision in the 2018 financial statements, on April 5, 2019, the Company filed an appeal with the Ontario Divisional Court with respect to the OEB's DTA Decision. The appeal was heard on November 21, 2019, and a decision is pending.

On October 26, 2018, Hydro One filed a one-year inflation-based application with the OEB for the 2019 transmission revenue requirement. On December 20, 2018, the OEB issued a decision approving Hydro One's 2018 revenue requirement as interim for 2019. On April 25, 2019, the OEB issued its decision on Hydro One’s 2019 transmission rate application, and set the revenue index at 1.4% on a final basis effective May 1, 2019.

On March 21, 2019, Hydro One Networks filed a three-year Custom Incentive Rate application with the OEB for 2020-2022 transmission rates. On June 19, 2019, Hydro One filed updates to the application reflecting recent financial results and other adjustments. The hearing began on October 21, 2019, and concluded on November 4, 2019. The OEB decision is pending.

On December 10, 2019, the OEB approved Hydro One Networks' 2019 transmission revenue requirement and charges as interim effective January 1, 2020 until the new transmission revenue requirement and charges are approved by the OEB.

Hydro One Networks - Distribution

On March 31, 2017, Hydro One Networks filed a custom application with the OEB for 2018-2022 distribution rates under the OEB’s incentive-based regulatory framework (2018-2022 Distribution Application), which was subsequently updated on June 7 and December 21, 2017. The application reflects the level of capital investments required to minimize degradation in overall system asset condition, to meet regulatory requirements, and to maintain current reliability levels.

On March 7, 2019, the OEB rendered its decision on the 2018-2022 Distribution Application (2018-2022 Distribution Decision). In accordance with the 2018-2022 Distribution Decision, as well as the DTA Decision as noted above in “- Hydro One Networks - Transmission”, the Company filed its draft rate order reflecting updated revenue requirements of $1,459 million for 2018, $1,498 million for 2019, $1,532 million for 2020, $1,578 million for 2021, and $1,624 million for 2022. On June 11, 2019, the OEB approved the rate order confirming these updated revenue requirements, which include impacts of both the 2018-2022 Distribution Decision and the DTA Decision.

On March 26, 2019, the Company filed a motion to review and vary the OEB's decision as it relates to rates revenue requirement recovery of employer pension costs. Concurrently, the Company filed an appeal with the Ontario Divisional Court. The appeal was held in abeyance pending the outcome of the motion made before the OEB. During the year, the Company reflected a portion of pension costs incurred in the Hydro One Networks' distribution Pension Cost Differential regulatory account, pending the outcome of the motion before the OEB. On December 19, 2019, the OEB affirmed its earlier decision with respect to recovery of the revenue requirement associated with pension costs. As a result, Hydro One derecognized the portion relating to pension costs charged to operations as a reversal of revenues of $13 million as this amount is no longer probable for recovery. Hydro One also transferred to property, plant and equipment and intangible assets the portion attributable to capital expenditures in the amount of $37 million. Hydro One has decided to discontinue its appeal of the OEB decision with the Ontario Divisional Court.

Hydro One Remote Communities

On November 5, 2018, Hydro One Remote Communities filed an application with the OEB seeking approval for increased base rates of 1.8% effective May 1, 2019. On February 11, 2019, the OEB issued a draft decision approving the requested increase, which was later finalized on March 28, 2019. On November 15, 2019, Hydro One Remote Communities filed an application with the OEB seeking approval for increased base rates of 2.0% effective May 1, 2020. A decision from the OEB is pending.

Hydro One Remote Communities is fully financed by debt and is operated as a break-even entity with no ROE.

NRLP

On September 19, 2018, NRLP was formed to own and operate a new 230 kV transmission line (Niagara Line) in the Niagara region. The Niagara Line enables generators in the Niagara area to connect to the load centres of the Greater Toronto and Hamilton areas.

On September 27, 2018, Hydro One filed a transmission licence application with the OEB for NRLP. On October 25, 2018, Hydro One filed two other applications with the OEB relating to NRLP requesting approval for Hydro One Networks to sell the applicable Niagara Line assets to NRLP, and approval of interim rates to include in the 2019 Uniform Transmission Rates (UTRs). On December 20, 2018, the OEB issued a decision finding that the request for approval for an interim revenue requirement effective January 1, 2019 was premature but indicated that there would be an opportunity to adjudicate the matter at a later date.

In January 2019, construction on the project was halted due to a land dispute with the Haudenosaunee Confederacy Chiefs Council (HCCC). On March 1, 2019, Hydro One filed a letter with the OEB requesting that the three previously filed applications be heard together once the land dispute was resolved. On March 15, 2019, the OEB put the NRLP applications in abeyance per Hydro One’s request. Hydro One filed a Statement of Claim with the Ontario Superior Court of Justice for injunctive relief (injunction) against members of the HCCC among others. On July 15, 2019, Hydro One was granted the injunction. Hydro One resumed construction shortly thereafter.

On August 1, 2019, Hydro One filed an update to the three previously filed OEB applications and asked that the OEB resume adjudication of the applications. On August 30, 2019, the construction of the Niagara Line was completed, and on September 12, 2019, the OEB granted NRLP a transmission licence and granted Hydro One Networks leave to sell the applicable Niagara Line assets to NRLP. On September 18, 2019, the applicable Niagara Line assets were transferred from Hydro One Networks to NRLP. See section "Other Developments - NRLP" for additional information.

On September 26, 2019, the OEB approved NRLP’s request to establish a deferral account to record NRLP’s 2019 revenue requirement prior to its inclusion in the UTRs. On October 25, 2019, NRLP filed its revenue cap incentive rate application for 2020-2024. The OEB decision is pending.

On December 19, 2019, the OEB approved NRLP’s proposed 2020 revenue requirement of $9 million as interim effective January 1, 2020.

HOSSM

HOSSM is under a 10-year deferred rebasing period for years 2017-2026, as approved in the OEB MAAD decision dated October 13, 2016. In July 2018, HOSSM filed a 2019 application to allow for inflationary increase (revenue cap escalator index) to its previously approved revenue requirement. The revenue cap escalator index is designed to add inflationary increases to the revenue requirement on an annual basis. On June 20, 2019, the OEB approved the revenue cap escalator index at 1.1% (net) which was applied to HOSSM's base revenue requirement for 2019, effective February 1, 2019, and also approved the 2019-2026 revenue cap framework.

On December 17, 2019, the OEB issued a decision on HOSSM’s request for transmission revenue requirement for 2020. The OEB approved the revenue cap adjustment requesting an increase to the 2020 revenue requirement of 1.5% (inflation factor 1.8% less stretch factor 0.3%).

B2M LP

On July 31, 2019, B2M LP filed a transmission rate application for 2020-2024, seeking a base revenue requirement of $36 million for 2020, and a 1.4% revenue cap escalator index for 2021 to 2024. On December 9, 2019, B2M LP reached a settlement on all issues with OEB staff and Intervenors on the 5-year revenue cap rate application for 2020-2024 to be effective January 1, 2020. The settlement accepts all of B2M LP’s cost submissions, but includes additional reliability reporting and a capital adjustment (reduction) factor of 0.6% to account for the lower rate base value. On January 6, 2020, the settlement agreement was filed with the OEB for approval, and was approved on January 16, 2020.

MAAD Applications

Orillia Power MAAD Application

In 2016, Hydro One filed a MAAD application (2016 Application) with the OEB to acquire Orillia Power Distribution Corporation (Orillia Power) from the City of Orillia, Ontario. On April 12, 2018, the OEB issued a decision denying Hydro One's proposed acquisition of Orillia Power. On September 26, 2018, Hydro One filed a new MAAD application (2018 Application) with the OEB to acquire Orillia Power. The evidence in the 2018 Application is similar to that provided in the 2016 Application. However, it includes

additional information that was not available at the time Hydro One filed its 2016 Application, including updates to reflect current variables to costs and other metrics, as well as future cost structures pertaining to the acquired entity.

On October 16, 2018, the School Energy Coalition (SEC) filed a motion with the OEB seeking an order dismissing the 2018 Application. On January 16, 2019, Hydro One and Orillia Power filed submissions on the SEC motion, maintaining that the motion should be dismissed, and that the 2018 Application should be heard by the OEB. On March 12, 2019, the OEB dismissed SEC's motion. At the request of Hydro One, on March 21, 2019, the OEB cancelled the deadlines for interrogatories to allow Hydro One to file amended or supplemental evidence in response to the OEB decision on Hydro One’s 2018-2022 Distribution Application. Hydro One filed the supplemental evidence on April 26, 2019. A transcribed technical conference was held on October 3-4, 2019, followed by an oral hearing on December 2-3, 2019. A decision by the OEB is pending.

Peterborough Distribution MAAD Application

On October 12, 2018, the Company filed an application with the OEB for approval of the acquisition of the business and distribution assets of Peterborough Distribution Inc. (Peterborough Distribution). On October 25, 2018, an advance ruling certification application was filed with the Competition Bureau. On November 14, 2018, the Competition Bureau issued a no action letter, meaning that the transaction can proceed from the Competition Bureau’s perspective. At the request of Hydro One, on March 21, 2019, the OEB allowed Hydro One to file amended or supplemental evidence in response to the OEB decision on Hydro One’s 2018-2022 Distribution Application. Hydro One filed the supplemental evidence on April 26, 2019. A transcribed technical conference was held on October 3-4, 2019, followed by an oral hearing on December 2-3, 2019. A decision by the OEB is pending.

2019 Federal and Ontario Budgets

Certain 2019 federal and Ontario budget measures enacted during the year ended December 31, 2019 provide certain time-limited investment incentives permitting Hydro One to deduct Accelerated CCA of up to three times the first-year rate for eligible capital investments acquired after November 20, 2018 and placed in-service before January 1, 2028. In 2019, the Accelerated CCA resulted in a temporary reduction in the Company’s ETR and the recognition of a tax regulatory liability relating to the Accelerated CCA that has not been reflected in the OEB approved rates. The timing of the disposition of the tax regulatory liability is subject to OEB approval, and may have a material impact on Hydro One’s future cash flows in the near term.

Impact

Hydro One expects that the OEB’s March 7, 2019 decision relating to the sharing of the Company’s deferred tax asset, the Merger-related costs, and the Accelerated CCA will lower the Company's ETR to a range of approximately 6% to 13% in the next five years.

Disclosure of Ownership by the Province

On June 6, 2017, the Canadian securities regulatory authorities granted (i) the Minister of Energy, (ii) OPG (on behalf of itself and the segregated funds established as required by the Nuclear Fuel Waste Act (Canada)) and (iii) agencies of the Crown, provincial Crown corporations and other provincial entities (collectively, the Non-Aggregated Holders) exemptive relief, subject to certain conditions, to enable each Non-Aggregated Holder to treat securities of Hydro One that it owns or controls separately from securities of Hydro One owned or controlled by the other Non-Aggregated Holders for purposes of certain take-over bid, early warning reporting, insider reporting and control person distribution rules and certain distribution restrictions under Canadian securities laws. Hydro One was also granted relief permitting it to rely solely on insider reports and early warning reports filed by Non-Aggregated Holders when reporting beneficial ownership or control or direction over securities in an information circular or annual information form in respect of securities beneficially owned or controlled by any Non-Aggregated Holder subject to certain conditions.

US GAAP

On March 27, 2018, Hydro One was granted exemptive relief by securities regulators in each province and territory of Canada which allows Hydro One to continue to report its financial results in accordance with US GAAP (Exemptive Relief). The Exemptive Relief will remain in effect until the earlier of: (i) January 1, 2024; (ii) the first day of Hydro One’s financial year that commences after Hydro One ceases to have activities subject to rate regulation; and (iii) the effective date prescribed by the International Accounting Standards Board for the mandatory application of a standard within International Financial Reporting Standards specific to entities with activities subject to rate regulation.

NRLP

In 2018, Hydro One entered into an agreement with the First Nations Partners, wherein a noncontrolling equity interest in Hydro One’s limited partnership, NRLP, would be made available for purchase at fair value by the First Nations Partners. On September 19, 2018, NRLP was formed to own the Niagara Line in the Niagara region. The Niagara Line enables generators in the Niagara area to connect to the load centres of the Greater Toronto and Hamilton areas. Hydro One Networks maintains and operates the Niagara Line in accordance with an operation and management services agreement.

On September 18, 2019, the applicable Niagara Line assets were transferred from Hydro One Networks to NRLP for $119 million and operation of the line was contracted to Hydro One Networks. This transfer was financed with 60% debt ($71 million) and 40% equity ($48 million). The cash payment of $71 million was financed by debt sourced by NRLP from a Hydro One subsidiary, and the $48 million equity comprised of partnership units issued by NRLP to Hydro One Networks. Subsequently, on the same date, Hydro One Networks sold to the Six Nations of the Grand River Development Corporation and, through a trust, to the Mississaugas of the Credit First Nation a 25.0% and 0.1%, respectively, equity interest in NRLP for total consideration of $12 million, representing the fair value of the equity interest acquired.

In addition, the Mississaugas of the Credit First Nation had an option to purchase an additional 19.9% equity interest in NRLP from Hydro One Networks at a price based on the value of the Niagara Line assets on the date of the closing, subject to certain conditions. On December 31, 2019, the Mississaugas of the Credit First Nation exercised the option.

On January 31, 2020, the Mississaugas of the Credit First Nation purchased an additional 19.9% equity interest in NRLP. On this date, Hydro One Networks sold to the Mississaugas of the Credit First Nation, through a trust, a 19.9% equity interest in NRLP for total consideration of $9 million. Following this transaction, Hydro One's interest in NRLP was reduced to 55%, with the Six Nations of the Grand River Development Corporation and the Mississaugas of the Credit First Nation owning 25% and 20%, respectively, of equity interest in NRLP.

Avista Corporation

In July 2017, Hydro One reached an agreement to acquire Avista Corporation. On January 23, 2019, Hydro One and Avista Corporation announced that the companies had mutually agreed to terminate the Merger agreement. As a result of the termination of the Merger agreement, on January 24, 2019, Hydro One paid a US$103 million termination fee to Avista Corporation as required by the Merger agreement. In January 2019, the Company cancelled the Acquisition Credit Facilities, with no amounts drawn. On

February 1, 2019, Hydro One entered into the Demand Facility which was used to fund the payment of the Merger termination fee and other Merger-related costs. On June 6, 2019, the $170 million drawn on the Demand Facility was repaid, and the Demand Facility is no longer available. On February 8, 2019, Hydro One redeemed the convertible debentures issued in 2017 and paid the holders of the instalment receipts $513 million ($333 per $1,000 principal amount) plus accrued and unpaid interest of $7 million. The redemption of the convertible debentures was paid with cash on hand. As a result of the termination of the Merger agreement, the Foreign-Exchange Contract terminated, with no amounts paid or received by Hydro One.

The following amounts related to the termination of the Merger agreement were recorded by the Company during the year ended December 31, 2019. All amounts were recognized in the first quarter.

•	$138 million for payment of the US$103 million Merger termination fee recorded in OM&A costs;
•	$22 million financing charges, due to reversal of previously recorded unrealized gains upon termination of the Foreign-Exchange Contract;

At December 31, 2019, Hydro One had a skilled and flexible work force of approximately 5,700 regular employees and 2,300 non-regular employees province-wide, comprising a mix of skilled trades, engineering, professional, managerial and executive personnel. Hydro One’s regular employees are supplemented primarily by accessing a large external labour force available through arrangements with the Company’s trade unions for contingent workers, sometimes referred to as “hiring halls”, and also by access to contract personnel. The hiring halls offer Hydro One the ability to flexibly use highly trained and appropriately skilled workers on a project-by-project and seasonal basis.

^1^^^Includes 675 non-regular “hiring hall” employees covered by the PWU agreement.

^2^	The average number of Hydro One employees in 2019 was approximately 8,800, consisting of approximately 5,800 regular employees and approximately 3,000 non-regular employees.

Collective Agreements

The current collective agreement with the PWU (for classifications other than Customer Service Operations (CSO)) expires on March 31, 2020. The collective agreement with the PWU for CSO was set to expire on September 30, 2019; however, it was extended to allow for bargaining at the same time as the non-CSO agreement. In January 2020, Hydro One and the PWU commenced collective bargaining with the official exchange of bargaining agendas. Both sides acknowledged their commitment to working towards the timely completion of collective bargaining.

In March 2019, Hydro One reached an agreement with the Society for a renewal of the collective agreement covering approximately 1,500 employees in critical engineering, supervisory and administrative roles. The agreement is for a two-year term, covering April 1, 2019 to March 31, 2021. The agreement was ratified by the Society on April 30, 2019.

Hydro One’s five-year collective agreement with the CUSW expires on April 30, 2022.

The construction building trade unions have collective agreements with the Electrical Power Systems Construction Association (EPSCA). EPSCA is an employers’ association of which Hydro One is a member. A number of the EPSCA construction collective agreements, which bind Hydro One, expire on April 30, 2020. Ratified five-year renewal collective agreements, covering May 1, 2020 to April 30, 2025, have been reached with The Carpenters, The Boilermakers, The United Association of Plumbers and Pipefitters, The Painters, and The Sheet Metal Workers. EPSCA is currently in the process of negotiating agreements or scheduling negotiating dates with the other building trades.

Stock-based Compensation

The Company granted awards under its LTIP, consisting of Performance Share Units (PSUs), Restricted Share Units (RSUs), and Stock Options. At December 31, 2019 and 2018, the following LTIP awards were outstanding:

December 31 (number of units)	2019	2018
PSUs	171,344	605,180
RSUs	206,993	442,470
Stock Options	403,550	949,910

NON-GAAP MEASURES

FFO, basic and diluted Adjusted EPS, adjusted net income, revenues, net of purchased power, and distribution revenues, net of purchased power are not recognized measures under US GAAP and do not have a standardized meaning prescribed by US GAAP. They are therefore unlikely to be directly comparable to similar measures presented by other companies. They should not be considered in isolation nor as a substitute for analysis of the Company’s financial information reported under US GAAP.

FFO

FFO is defined as net cash from operating activities, adjusted for (i) changes in non-cash balances related to operations, (ii) dividends paid on preferred shares, and (iii) distributions to noncontrolling interest. Management believes that FFO is helpful as a supplemental measure of the Company’s operating cash flows as it excludes timing-related fluctuations in non-cash operating working capital and cash flows not attributable to common shareholders. As such, FFO provides a consistent measure of the cash generating performance of the Company’s assets.

Adjusted Net Income and Adjusted EPS

The following adjusted net income, and basic and diluted Adjusted EPS have been calculated by management on a supplementary basis which adjusts net income under US GAAP for income and costs related to the Merger. Adjusted net income and Adjusted EPS are used internally by management to assess the Company’s performance and are considered useful because they exclude the impact of Merger-related costs, including gains and losses on the Foreign-Exchange Contract, as well as the impacts related to the OEB's DTA Decision on Hydro One Networks' distribution and transmission businesses. Adjusted net income and Adjusted EPS provide users with a comparative basis to evaluate the current ongoing operations of the Company compared to prior year.

RISK MANAGEMENT AND RISK FACTORS

Hydro One is subject to numerous risks and uncertainties. Critical to Hydro One’s success is the identification, management, and to the extent possible, mitigation of these risks. Hydro One’s Chief Risk Officer has accountability for the Company’s Enterprise Risk Management (ERM) program, which assists decision-makers throughout the organization with the management of key business risks, including new and emerging risks and opportunities.

The material risks relating to Hydro One and its business that the Company believes would be the most likely to influence an investor’s decision to purchase Hydro One’s securities are set out in the risk factors below. These risks could have a materially adverse effect on the Company or its business, financial condition, or operations. This list is not a comprehensive list of all the risks to the Company, and the actual effect of any of the risks cited below could be materially different from what is described below. Additionally, other risks may arise or risks currently not considered material may become material in the future.

Risks Relating to Hydro One’s Business

Regulatory Risks and Risks Relating to Hydro One’s Revenues

Risks Relating to Obtaining Rate Orders

The Company is subject to the risk that the OEB will not approve the Company’s transmission and distribution revenue requirements requested in outstanding or future applications for rates. Rate applications for revenue requirements are subject to the OEB’s review process, usually involving participation from intervenors and a public hearing process. There can be no assurance that resulting decisions or rate orders issued by the OEB will permit Hydro One to recover all costs actually incurred, costs of debt and income taxes, or to earn a particular ROE. A failure to obtain acceptable rate orders, or approvals of appropriate returns on equity and costs actually incurred, may materially adversely affect: Hydro One’s transmission or distribution businesses, the undertaking or timing of capital expenditures, ratings assigned by credit rating agencies, the cost and issuance of long-term debt, and other matters, any of which may in turn have a material adverse effect on the Company. In addition, there is no assurance that the Company will receive regulatory decisions in a timely manner and, therefore, the Company may incur costs before having an approved revenue requirement and cash flows could be impacted.

Risks Relating to Actual Performance Against Forecasts

The Company’s ability to recover the actual costs of providing service and earn the allowed ROE depends on the Company achieving its forecasts established and approved in the rate-setting process. Actual costs could exceed the approved forecasts if, for example, the Company incurs operations, maintenance, administration, capital and financing costs above those included in the Company’s approved revenue requirement. The inability to obtain acceptable rate decisions or to recover any significant difference between forecast and actual expenses could materially adversely affect the Company’s financial condition and results of operations.

Further, the OEB approves the Company’s transmission and distribution rates based on projected electricity load and consumption levels, among other factors. If actual load or consumption materially falls below projected levels, the Company’s revenue and net

23

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

income for either, or both, of these businesses could be materially adversely affected. Also, the Company’s current revenue requirements for these businesses are based on cost and other assumptions that may not materialize. There is no assurance that the OEB would allow rate increases sufficient to offset unfavourable financial impacts from unanticipated changes in electricity demand or in the Company’s costs.

The Company is subject to risk of revenue loss from other factors, such as economic trends and conditions, changes in service territory, and weather conditions that influence the demand for electricity. The Company’s overall operating results may fluctuate substantially on a seasonal and year-to-year basis based on these trends and weather conditions. For instance, a cooler than normal summer or warmer than normal winter can be expected to reduce demand for electricity below that forecast by the Company, causing a decrease in the Company’s revenues from the same period of the previous year.

The Company’s load could also be negatively affected by successful CDM programs whose results exceed forecasted expectations.

Risks Relating to Other Applications to the OEB

Hydro One may face increased competition with other transmitters for opportunities to build new, large-scale transmission facilities in Ontario. The Company is subject to the risk that it will not be selected to build new transmission in Ontario, which could impair growth, disrupt operations and/or development, or have other adverse impacts. The Company is also subject to the risk that it will not obtain, or will not obtain in a timely manner, required regulatory approvals for other matters, such as leave to construct applications, applications for mergers, acquisitions, amalgamations and divestitures, and environmental approvals. Decisions to acquire or divest other regulated businesses licensed by the OEB are subject to OEB approval. Accordingly, there is the risk that such matters may not be approved, that the Company may not be selected to build new transmission as part of the competitive process, or that unfavourable conditions will be imposed by the OEB.

Risks Relating to Rate-Setting Models for Transmission and Distribution

The OEB approves and periodically changes the rate-setting models and methodology for the transmission and distribution businesses. Changes to the application type, filing requirements, rate-setting model or methodology, or revenue requirement determination may have a material negative impact on Hydro One’s revenue and net income. For example, the OEB may in the future decide to reduce the allowed ROE for either of these businesses, modify the formula or methodology it uses to determine the ROE, or reduce the weighting of the equity component of the deemed capital structure. Any such reduction could reduce the net income of the Company. Similarly, the OEB is currently considering other utility remuneration models, and any such change could affect Hydro One’s revenue and net income.

The OEB’s recent Custom Incentive Rate-setting model requires that the term of a custom rate application be for multi-year periods. There are risks associated with forecasting key inputs such as revenues, operating expenses and capital over such a long period. For instance, if unanticipated capital expenditures arise that were not contemplated in the Company’s most recent rate decision, the Company may be required to incur costs that may not be recoverable until a future period or not recoverable at all in future rates. This could have a material adverse effect on the Company.

When rates are set for a multi-year period, including under a Custom Incentive Rate application, the OEB expects there to be no further rate applications for annual updates within the multi-year period, unless there are exceptional circumstances, with the exception of the clearance of established deferral and variance accounts. For example, the OEB does not expect to address annual rate applications for updates for cost of capital (including ROE), working capital allowance or sales volumes. If there were an increase in interest rates over the period of a rate decision and no corresponding changes were permitted to the Company’s allowed cost of capital (including ROE), then the result could be a decrease in the Company’s financial performance.

To the extent that the OEB approves an In-Service Variance Account for the transmission and/or distribution businesses, and should the Company fail to meet the threshold levels of in-service capital, the OEB may reclaim a corresponding portion of the Company’s revenues.

Risks Relating to Capital Expenditures

In order to be recoverable in rates, capital expenditures require the approval of the OEB. There can be no assurance that all capital expenditures, including any imposed by or resulting from government or regulatory bodies, incurred by Hydro One will be approved by the OEB. For example, capital cost overruns, unexpected capital expenditures in maintaining or improving the Company’s assets, unexpected costs as a result of proposed legislation, including that relating to the expansion of broadband service in Canada, may not be recoverable in transmission or distribution rates. To the extent possible, Hydro One aims to mitigate this risk by ensuring expenditures are reasonable and prudent, and also by seeking from the regulator clear policy direction on cost responsibility, and by obtaining pre-approval of the need for capital expenditures.

Any regulatory decision by the OEB to disallow or limit the recovery of any capital expenditures would lead to a lower-than-expected approved revenue requirement or rate base, potential asset impairment or charges to the Company’s results of operations, any of which could have a material adverse effect on the Company.

Risk of Recoverability of Total Compensation Costs

Hydro One manages all of its total compensation costs, including pension and other post-employment and post-retirement benefits (OPEBs), subject to restrictions and requirements imposed by the collective bargaining process and legislative requirements. Any element of total compensation costs which is disallowed in whole or part by the OEB and therefore not recoverable from customers

in rates could result in costs which could be material and could decrease net income, which could have a material adverse effect on the Company. Legislation restricts Hydro One from recovering specified executive compensation costs from the OEB.

The Company provides OPEBs, including workers compensation benefits and long-term disability benefits to qualifying employees. Hydro One currently maintains the accrual accounting method with respect to OPEBs. If the OEB directed Hydro One to transition to a different accounting method for OPEBs or otherwise adjusted the basis of recovery for OPEB costs, this could result in income volatility, due to an inability of the Company to book the difference between the accrual and cash as a regulatory asset, and the Company might not be able to recover some costs. A determination that some of the Company’s post-employment and post-retirement benefit costs are not recoverable could have a material adverse effect on the Company.

Risks Relating to Regulatory Treatment of Deferred Tax Asset

As a result of leaving the payments in lieu of corporate income taxes (PILs) regime and entering the federal tax regime in connection with the 2015 initial public offering (IPO) of the Company, Hydro One recorded additional deferred tax assets due to the revaluation of the tax basis of Hydro One’s fixed assets at their fair market value and recognition of eligible capital expenditures. At the time of the IPO, the Company determined the tax savings derived from the additional deferred tax assets should accrue to the shareholders of Hydro One Limited. The OEB’s September 28, 2017 Original Decision (see details above in “Regulation - Electricity Rates Applications - Hydro One Networks - Transmission”) altered Hydro One’s allocation of the tax savings derived from the additional deferred tax assets and determined that a portion of the tax savings should accrue to ratepayers. In October 2017, the Company filed a motion to review and vary (Motion) the Original Decision and filed an appeal with the Ontario Divisional Court (Appeal) which was stayed pending the outcome of the Motion. In both cases, the Company's position was that the OEB made errors of fact and law in its determination of the allocation of the tax savings between shareholders and ratepayers.

On March 7, 2019, the OEB issued a decision upholding its Original Decision on the handling of the deferred tax asset. Also, on March 7, 2019, the OEB issued its decision for Hydro One Networks’ 2018-2022 distribution rates in which it directed the Company to apply the Original Decision to Hydro One Networks’ distribution rates. Based on these decisions, the Company recognized a total one-time $867 million decrease to net income. On April 5, 2019, the Company filed a motion to commence a new appeal with respect to the OEB’s deferred tax asset decision. The appeal was heard on November 21, 2019, and a decision is pending. Loss of the appeal, in whole or in part, could have a material adverse effect on the Company.

Risks Relating to Government Action

The Province is, and is likely to remain, the largest shareholder in Hydro One Limited. The Province may be in a position of conflict from time to time as a result of being an investor in Hydro One Limited and also being a government actor setting broad policy objectives in the electricity industry. Government actions may not be in the interests of the Company or investors.

Governments may pass legislation or issue regulations at any time, including legislation or regulation impacting Hydro One, which could have potential material adverse effects on Hydro One and its business. Such government actions may include, but are not limited to, legislation, regulation, directives or shareholder action intended to reduce electricity rates, place constraints on compensation, or affect the governance of Hydro One. Such government actions could adversely affect the Company’s financial condition and results of operations, as well as public opinion and the Company’s reputation. Government action may also hinder Hydro One’s ability to pursue its strategy and/or objectives.

Additionally, involvement by the Province in placing constraints on executive compensation (through the compensation framework implemented as a result of the Hydro One Accountability Act, 2018) may inhibit the Company’s ability to attract and retain qualified executive talent, which may also impact the Company’s performance, strategy and/or objectives. The failure to attract and retain qualified executives could have a material adverse effect on the Company.

Government action may also impact the Company’s credit ratings as the Company’s credit ratings reflect, in part, the rating agencies’ assessment of government involvement in the business of Hydro One. The Company cannot predict what actions rating agencies may take in the future, positive or negative, including in response to government action or inaction relating to or impacting Hydro One. The failure to maintain the Company’s current credit ratings could adversely affect the Company’s financial condition and results of operations, and a downgrade in the Company’s credit ratings could restrict the Company’s ability to access debt capital markets and increase the Company’s cost of debt.

Indigenous Claims Risk

Some of the Company’s current and proposed transmission and distribution assets are or may be located on reserve (as defined in the Indian Act (Canada)) (Reserve) lands, or lands over which Indigenous people have Aboriginal, treaty, or other legal claims. Some Indigenous leaders, communities, and their members have made assertions related to sovereignty and jurisdiction over Reserve lands and traditional territories (land traditionally occupied or used by a First Nation, Métis or Inuit group) and are increasingly willing to assert their claims through the courts, tribunals, or direct action. These claims, and/or the settlement or resolution of these claims could have a material adverse effect on the Company or otherwise materially adversely impact the Company’s operations, including the development of current and future projects.

The Company’s operations and activities may give rise to the Crown’s duty to consult and potentially accommodate Indigenous communities. Procedural aspects of the duty to consult may be delegated to the Company by the Province or the federal government. A perceived failure by the Crown to sufficiently consult an Indigenous community, including communities with a traditional governance model not recognized under the Indian Act, or a perceived failure by the Company in relation to delegated consultation obligations,

25

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

could result in legal challenges against the Crown or the Company, including judicial review or injunction proceedings, or could potentially result in direct action against the Company by a community or its citizens. If this occurs, it could disrupt or delay the Company’s operations and activities, including current and future projects, and have a material adverse effect on the Company.

Risk from Transfer of Assets Located on Reserves

The transfer orders by which the Company acquired certain of Ontario Hydro’s businesses as of April 1, 1999 did not transfer title to assets located on Reserves. The transfer of title to these assets did not occur because authorizations originally granted by the federal government for the construction and operation of these assets on Reserves could not be transferred without required consent. In several cases, the authorizations had either expired or had never been issued.

Currently, OEFC holds legal title to these assets and it is expected that the Company will manage them until it has obtained permits to complete the title transfer. To occupy Reserves, the Company must have valid permits. For each permit, the Company must negotiate an agreement (in the form of a memorandum of understanding) with the First Nation, OEFC and any members of the First Nation who have occupancy rights. The agreement includes provisions whereby the First Nation consents to the issuance of a permit. For transmission assets, the Company must negotiate terms of payment. It is difficult to predict the aggregate amount that the Company may have to pay to obtain the required agreements from First Nations. If the Company cannot reach satisfactory agreements with the relevant First Nation to obtain federal permits, it may have to relocate these assets to other locations and restore the lands at a cost that could be substantial. In a limited number of cases, it may be necessary to abandon a line and replace it with diesel generation facilities. In either case, the costs relating to these assets could have a material adverse effect on the Company if the costs are not recoverable in future rate orders.

Executive Recruitment and Retention Risk

Involvement by the Province relating to executive compensation, and Hydro One executive compensation constraints flowing from the Hydro One Accountability Act, 2018, may inhibit the Company’s ability to attract and retain qualified executive talent. The Company’s strategy is tied to its ability to continue to attract and retain qualified executives. The failure to attract and retain qualified executives could have a material adverse effect on the Company.

Compliance with Laws and Regulations

Hydro One must comply with numerous laws and regulations affecting its business, including requirements relating to transmission and distribution companies, environmental laws, employment laws and health and safety laws. The failure of the Company to comply with these laws could have a material adverse effect on the Company’s business. See also “- Environment Risk” and “- Health and Safety Risk”.

For example, Hydro One’s licensed transmission and distribution businesses are required to comply with the terms of their licences, with codes and rules issued by the OEB, and with other regulatory requirements. In Ontario, the Market Rules issued by the IESO require the Company to, among other things, comply with applicable reliability standards established by the North American Electric Reliability Corporation (NERC) and Northeast Power Coordinating Council, Inc. (NPCC). The costs associated with compliance with these reliability standards are expected to be recovered through rates, but there can be no assurance that the OEB will approve the recovery of all of such costs. Failure to obtain such approvals could have a material adverse effect on the Company.

There is the risk that new legislation, regulations, requirements or policies will be introduced in the future. These may reduce Hydro One’s revenue, or may require Hydro One to incur additional costs, which may or may not be recovered in future transmission and distribution rates.

Risk of Natural and Other Unexpected Occurrences

The Company’s facilities are exposed to the effects of severe weather conditions, natural disasters, man-made events including, but not limited to, cyber and physical terrorist type attacks, events which originate from third-party connected systems, and any other potentially catastrophic events. The Company’s facilities may not withstand occurrences of these types in all circumstances.

The Company could also be subject to claims for damages from events which may be proximately connected with the Company’s assets (for example, forest fires), claims for damages caused by its failure to transmit or distribute electricity or costs related to ensuring its continued ability to transmit or distribute electricity.

The Company does not have insurance for damage to its transmission and distribution wires, poles and towers located outside its transmission and distribution stations resulting from these or other events. Where insurance is available for the Company’s other assets and for damage claims, such insurance coverage may have deductibles, limits and/or exclusions that may still expose the Company to material losses. Losses from lost revenues and repair costs could be substantial, especially for many of the Company’s facilities that are located in remote areas.

In the event that the Company is unable to recover such costs, this could have a material adverse effect on the Company.

Environment Risk

The Company is subject to extensive Canadian federal, provincial and municipal environmental regulation. Failure to comply could subject the Company to fines or other penalties. In addition, the presence or release of hazardous or other harmful substances could lead to claims by third parties or governmental orders requiring the Company to take specific actions such as investigating,

26

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

controlling and remediating the effects of these substances. Although Hydro One is not a large emitter of greenhouse gases, the Company monitors its emissions to track and report on all sources, including sulphur hexafluoride or “SF6”. The Company could be subject to costs and other risks related to emissions. Contamination of the Company’s properties could limit its ability to sell or lease these assets in the future.

In addition, actual future environmental expenditures may vary materially from the estimates used in the calculation of the environmental liabilities provided for in the Company’s financial statements. The Company does not have insurance coverage for these environmental expenditures.

There is also risk associated with obtaining governmental approvals, permits, or renewals of existing approvals and permits related to constructing or operating facilities. This may require environmental assessment or result in the imposition of conditions, or both, which could result in delays and cost increases. Failure to obtain necessary approvals or permits could result in an inability to complete projects which may have a material adverse effect on the Company.

The Company’s facilities are exposed to the effects of severe weather conditions and natural disasters. The Company recognizes the risks associated with potential climate change and has developed plans to respond as appropriate. Climate change may have the effect of shifting weather patterns and increasing the severity and frequency of extreme weather events and natural disasters, which could impact Hydro One’s business. The Company’s facilities may not withstand occurrences of these types in all circumstances. Notwithstanding Hydro One’s efforts to adapt and increase grid resilience, the Company’s facilities are exposed to risks which may have an adverse effect on grid resilience. The Company could also be subject to claims for damages from events which may be proximately connected with the Company’s assets (for example, forest fires), claims for damages caused by its failure to transmit or distribute electricity or costs related to ensuring its continued ability to transmit or distribute electricity. The Company does not have insurance for damage to its transmission and distribution wires, poles and towers located outside its transmission and distribution stations resulting from these or other events. Where insurance is available for the Company’s other assets and for damage claims, such insurance coverage may have deductibles, limits and/or exclusions that may still expose the Company to material losses. Losses from lost revenues and repair costs could be substantial, especially for many of the Company’s facilities that are located in remote areas.

In the event that the Company is unable to recover such costs, this could have a material adverse effect on the Company.

Risk Associated with Information Technology (IT), Operational Technology (OT) Infrastructure and Data Security

The Company’s ability to operate effectively in the Ontario electricity market is, in part, dependent upon it developing, modernizing, maintaining and managing complex IT and OT systems which are employed to operate and monitor its transmission and distribution facilities, financial and billing systems and other business systems. The Company’s increasing reliance on information systems and expanding data networks, as well as growing volume and complexity of data, increases its vulnerability, and exposure to information security threats. The Company’s transmission business is required to comply with various rules and standards for transmission reliability, including mandatory standards established by the NERC and the NPCC. These include standards relating to cyber-security and OT, which only apply to certain of the Company’s assets (generally being those whose failure could impact the functioning of the bulk electricity system). The Company may maintain different or lower levels of security for its assets that are not subject to these mandatory standards. The Company must also comply with various cyber-security and privacy-related regulatory requirements under the OEB’s Ontario Cyber Security Framework and legislative and licence requirements relating to the collection, use and disclosure of personal information and information regarding consumers, wholesalers, generators and retailers.

Cyber-attacks or unauthorized access to corporate IT and OT systems could result in service disruptions and system failures, which could have a material adverse effect on the Company, including as a result of a failure to provide electricity to customers. Because it operates critical infrastructure, Hydro One may be at greater risk of cyber-attacks from third parties (including state run or controlled parties) that could impair or incapacitate its assets. In addition, in the course of its operations, the Company collects, uses, processes and stores information which could be exposed in the event of a cyber-security incident or other unauthorized access or disclosure, such as information about customers, suppliers, counterparties, employees and other third parties.

Security and system disaster recovery controls are in place; however, there can be no assurance that there will not be system failures or security breaches or that such threats would be detected or mitigated on a timely basis. Upon occurrence and detection, the focus would shift from prevention to isolation, remediation and recovery until the incident has been fully addressed. Any such system failures or security breaches could have a material adverse effect on the Company.

Labour Relations Risk

The substantial majority of the Company’s employees are represented by either the PWU or the Society. Over the past several years, significant effort has been expended to increase Hydro One’s flexibility to conduct operations in a more cost-efficient manner. Although the Company has achieved improved flexibility in its collective agreements, the Company may not be able to achieve further improvements. The Company reached an agreement with the Society for a collective agreement, covering the period from April 1, 2019 to March 31, 2021. The Company also reached a collective agreement with the PWU, covering the period from April 1, 2018 to March 31, 2020, and a collective agreement with the CUSW, covering the period from May 1, 2017 to April 30, 2022. Additionally, EPSCA and a number of building trade unions have agreements, to which Hydro One is bound, covering the period from May 1, 2015 to April 30, 2020, some of which have been renewed to cover the period from May 1, 2020 to April 30, 2025 (see “Hydro One Work Force - Collective Agreements” for details). Agreements were also reached with the Society and the PWU to facilitate the insourcing of CSO services effective March 1, 2018. Future negotiations with unions present the risk of a labour

27

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

disruption or dispute, risk to the Company’s ability to sustain the continued supply of energy to customers, as well as potential risks to public safety. The Company also faces financial risks related to its ability to negotiate collective agreements consistent with its rate orders. Any of these could have a material adverse effect on the Company. Collective agreements requiring renewal in 2020 include the PWU and PWU CSO agreements, as well as the agreements between EPSCA and the building trades (see “Hydro One Work Force - Collective Agreements” for details). Failure to renew these agreements on terms acceptable to Hydro One could have a material adverse effect on its business and results of operations and expose Hydro One to the risks notes above.

Work Force Demographic Risk

By the end of 2019, approximately 15% of the Company’s employees who are members of the Company’s defined benefit and defined contribution pension plans were eligible for retirement, and by the end of 2020, approximately 17% could be eligible. These percentages are not evenly spread across the Company’s work force, but tend to be most significant in the most senior levels of the Company’s staff and among management staff. During 2019, approximately 3% of the Company’s work force (down from 4% in 2018) elected to retire. Accordingly, the Company’s continued success will be tied to its ability to continue to attract and retain sufficient qualified staff to replace the capability lost through retirements and meet the demands of the Company’s work programs.

In addition, the Company expects the skilled labour market for its industry will remain highly competitive. Many of the Company’s current and potential employees being sought after possess skills and experience that are also highly coveted by other organizations inside and outside the electricity sector. The failure to attract, retain and deploy qualified personnel for Hydro One’s business could have a material adverse effect on the Company.

Risk Associated with Arranging Debt Financing

The Company expects to borrow to repay its existing indebtedness and to fund a portion of capital expenditures. Hydro One has substantial debt principal repayments, including $653 million in 2020, $803 million in 2021, and $604 million in 2022. In addition, from time to time, the Company may draw on its syndicated bank lines and/or issue short-term debt under Hydro One Inc.’s $2,300 million commercial paper program which would mature within one year of issuance. The Company also plans to incur continued material capital expenditures for each of 2020 and 2021. Cash generated from operations, after the payment of expected dividends, will not be sufficient to fund the repayment of the Company’s existing indebtedness and capital expenditures. The Company’s ability to arrange sufficient and cost-effective debt financing could be materially adversely affected by numerous factors, including the regulatory environment in Ontario, the Company’s results of operations and financial position, market conditions, the ratings assigned to its debt securities by credit rating agencies, an inability of the Company to comply with its debt covenants, and general economic conditions. A downgrade in the Company’s credit ratings could restrict the Company’s ability to access debt capital markets and increase the Company’s cost of debt. Any failure or inability on the Company’s part to borrow the required amounts of debt on satisfactory terms could impair its ability to repay maturing debt, fund capital expenditures and meet other obligations and requirements and, as a result, could have a material adverse effect on the Company.

Market, Financial Instrument and Credit Risk

Market risk refers primarily to the risk of loss that results from changes in costs, foreign exchange rates and interest rates. The Company is exposed to fluctuations in interest rates as its regulated ROE is derived using a formulaic approach that takes into account anticipated interest rates. The Company issues debt from time to time to refinance maturing debt and for general corporate purposes. The Company is therefore exposed to fluctuations in interest rates in relation to such issuances of debt. The Company is not currently exposed to material commodity price risk or material foreign exchange risk.

The OEB-approved adjustment formula for calculating ROE in a deemed regulatory capital structure of 60% debt and 40% equity provides for increases and decreases depending on changes in benchmark interest rates for Government of Canada debt and the A-rated utility corporate bond yield spread. For the transmission and distribution businesses in 2021, after transmission rates are set as part of a Custom Incentive Rate application, the OEB does not expect to address annual rate applications for updates to allowed ROE, so fluctuations will have no impact to net income. The Company has interest rate exposure on issuances of short- and long-term debt maturing in 2020 and beyond. The Company periodically uses interest rate swap agreements to mitigate elements of interest rate risk.

Financial assets create a risk that a counterparty will fail to discharge an obligation, causing a financial loss. Derivative financial instruments result in exposure to credit risk, since there is a risk of counterparty default. Hydro One monitors and minimizes credit risk through various techniques, including dealing with highly rated counterparties, limiting total exposure levels with individual counterparties, entering into agreements which enable net settlement, and by monitoring the financial condition of counterparties. The Company does not trade in any energy derivatives. The Company is required to procure electricity on behalf of competitive retailers and certain local distribution companies for resale to their customers. The resulting concentrations of credit risk are mitigated through the use of various security arrangements, including letters of credit, which are incorporated into the Company’s service agreements with these retailers in accordance with the OEB’s Retail Settlement Code.

The failure to properly manage these risks could have a material adverse effect on the Company.

28

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

Risks Relating to Asset Condition, Capital Projects and Innovation

The Company continually incurs sustainment and development capital expenditures and monitors the condition of its assets to manage the risk of equipment failures and to determine the need for and timing of major refurbishments and replacements of its transmission and distribution infrastructure.

While traditionally a mature and stable industry, the electricity industry is facing significant technological change and increasing innovation, the consequences of which could have a material adverse effect on the Company.

Execution of the Company’s capital expenditure programs is partially dependent on external factors, such as environmental approvals, municipal permits, equipment outage schedules that accommodate the IESO, generators and transmission-connected customers, and supply chain availability for equipment suppliers and consulting services. There may also be a need for, among other things, Environmental Assessment Act (Ontario) approvals, approvals which require public meetings, appropriate engagement with Indigenous communities, OEB approvals of expropriation or early access to property, and other activities. Obtaining approvals and carrying out these processes may also be impacted by opposition to the proposed site of the capital investments. Delays in obtaining required approvals or failure to complete capital projects on a timely basis could materially adversely affect transmission reliability or customers’ service quality or increase maintenance costs which could have a material adverse effect on the Company. Failure to receive approvals for projects when spending has already occurred would result in the inability of the Company to recover the investment in the project as well as forfeit the anticipated return on investment. The assets involved may be considered impaired and result in the write off of the value of the asset, negatively impacting net income. External factors are considered in the Company’s planning process. If the Company is unable to carry out capital expenditure plans in a timely manner, equipment performance may degrade, which may reduce network capacity, result in customer interruptions, compromise the reliability of the Company’s networks or increase the costs of operating and maintaining these assets. Any of these consequences could have a material adverse effect on the Company.

Increased competition for the development of large transmission projects and legislative changes relating to the selection of transmitters could impact the Company’s ability to expand its existing transmission system, which may have an adverse effect on the Company. To the extent that other parties are selected to construct, own and operate new transmission assets, the Company’s share of Ontario’s transmission network would be reduced.

Health and Safety Risk

Hydro One’s work environment can be inherently dangerous and there is a risk to health and safety of both the public and our employees, as well as possible resultant operational and/or financial impacts. The Company is subject to federal and provincial legislation and regulations relating to health and safety. Findings of a failure to comply with these requirements could result in penalties and reputational risk, which could negatively impact the Company. Failure to comply could subject the Company to fines or other penalties. Any regulatory decision to disallow or limit the recovery of such costs could have a material adverse effect on the Company.

Pension Plan Risk

Hydro One has the Hydro One Defined Benefit Pension Plan in place for the majority of its employees. Contributions to the pension plan are established by actuarial valuations which are required to be filed with the Financial Services Regulatory Authority of Ontario on a triennial basis. The most recently filed valuation was prepared as at December 31, 2018, and was filed in September 2019, covering a three-year period from 2019 to 2021. Hydro One’s contributions to its pension plan satisfy, and are expected to continue to satisfy, minimum funding requirements. Contributions beyond 2021 will depend on the funded position of the plan, which is determined by investment returns, interest rates and changes in benefits and actuarial assumptions at that time. A determination by the OEB that some of the Company’s pension expenditures are not recoverable through rates could have a material adverse effect on the Company, and this risk may be exacerbated if the amount of required pension contributions increases.

Hydro One currently reports and recovers its pension costs on a cash basis, and maintains the accrual method with respect to OPEBs. Transitioning from the cash basis to an accrual method for pension may have material negative rate impacts for customers or material negative impacts on the Company should recovery of costs be disallowed by the OEB.

See also “- Regulatory Risks and Risks Relating to Hydro One’s Revenues - Risk of Recoverability of Total Compensation Costs” for risks relating to recovery of pension costs.

Risk Associated with Outsourcing Arrangements

Hydro One has entered into an outsourcing arrangement with a third party for the provision of back office and IT services. If the services are disrupted, it could have a material adverse effect on the Company. Additionally, if the outsourcing arrangement or statements of work thereunder are terminated for any reason or expire before a new supplier is selected and fully transitioned, the Company could be required to transfer to another service provider or insource, which could have a material adverse effect on the Company’s business, operating results, financial condition or prospects.

Risk from Provincial Ownership of Transmission Corridors

The Province owns some of the corridor lands underlying the Company’s transmission system. Although the Company has the statutory right to use these transmission corridors, the Company may be limited in its options to expand or operate its systems.

29

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

Also, other uses of the transmission corridors by third parties in conjunction with the operation of the Company’s systems may increase safety or environmental risks, which could have a material adverse effect on the Company.

Litigation Risks

In the normal course of the Company’s operations, it becomes involved in, is named as a party to and is the subject of, various legal proceedings, including regulatory proceedings, tax proceedings and legal actions, relating to actual or alleged violations of law, common law damages claims, personal injuries, property damage, property taxes, land rights, the environment and contract disputes. The outcome of outstanding, pending or future proceedings cannot be predicted with certainty and may be determined adversely to the Company, which could have a material adverse effect on the Company. Even if the Company prevails in any such legal proceeding, the proceedings could be costly and time-consuming and would divert the attention of management and key personnel from the Company’s business operations, which could adversely affect the Company. See also “Other Developments - Litigation”.

Transmission Assets on Third-Party Lands Risk

Some of the lands on which the Company’s transmission assets are located are owned by third parties, including the Province and federal Crown, and are or may become subject to land claims by First Nations. The Company requires valid occupation rights to occupy such lands (which may take the form of land use permits, easements or otherwise). If the Company does not have valid occupational rights on third-party owned or controlled lands or has occupational rights that are subject to expiry, it may incur material costs to obtain or renew such occupational rights, or if such occupational rights cannot be renewed or obtained it may incur material costs to remove and relocate its assets and restore the subject land. If the Company does not have valid occupational rights and must incur costs as a result, this could have a material adverse effect on the Company or otherwise materially adversely impact the Company’s operations.

Reputational, Public Opinion and Political Risk

Reputation risk is the risk of a negative impact to Hydro One’s business, operations or financial condition that could result from a deterioration of Hydro One’s reputation. Hydro One’s reputation could be negatively impacted by changes in public opinion, attitudes towards the Company’s privatization, failure to deliver on its customer promises and other external forces. Adverse reputational events or political actions could have negative impacts on Hydro One’s business and prospects including, but not limited to, delays or denials of requisite approvals, such as denial of requested rates, and accommodations for Hydro One’s planned projects, escalated costs, legal or regulatory action, and damage to stakeholder relationships.

Risks Associated with Acquisitions

Acquisitions include inherent risks that some or all of the expected benefits may fail to materialize, or may not occur within the time periods anticipated, and Hydro One may incur material unexpected costs. Realization of the anticipated benefits would depend, in part, on the Company’s ability to successfully integrate the acquired business, including the requirement to devote management attention and resources to integrating business practices and support functions. The failure to realize the anticipated benefits, the diversion of management’s attention, or any delays or difficulties encountered in connection with the integration could have an adverse effect on the Company’s business, results of operations, financial condition or cash flows.

Risks Relating to the Company’s Relationship with the Province

Ownership and Continued Influence by the Province and Voting Power; Share Ownership Restrictions

The Province currently owns approximately 47.3% of the outstanding common shares of Hydro One. The Electricity Act restricts the Province from selling voting securities of Hydro One (including common shares) of any class or series if it would own less than 40% of the outstanding number of voting securities of that class or series after the sale and in certain circumstances also requires the Province to take steps to maintain that level of ownership. Accordingly, the Province is expected to continue to maintain a significant ownership interest in voting securities of Hydro One for an indefinite period.

As a result of its significant ownership of the common shares of Hydro One, the Province has, and is expected indefinitely to have, the ability to determine or significantly influence the outcome of shareholder votes, subject to the restrictions in the Governance Agreement. Despite the terms of the Governance Agreement in which the Province has agreed to engage in the business and affairs of the Company as an investor and not as a manager, there is a risk that the Province’s engagement in the business and affairs of the Company as an investor will be informed by its policy objectives and may influence the conduct of the business and affairs of the Company in ways that may not be aligned with the interests of other investors. Notwithstanding the Governance Agreement, and in light of actions historically taken by the Province, there can be no assurance that the Province will not take other actions in the future that could be detrimental to the interests of investors in Hydro One. See “Risks Relating to Government Action” above.

The share ownership restrictions in the Electricity Act (Share Ownership Restrictions) and the Province’s significant ownership of common shares of Hydro One together effectively prohibit one or more persons acting together from acquiring control of Hydro One. They also may limit or discourage transactions involving other fundamental changes to Hydro One and the ability of other shareholders to successfully contest the election of the directors proposed for election pursuant to the Governance Agreement. The Share Ownership Restrictions may also discourage trading in, and may limit the market for, the common shares and other voting securities.

30

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

Nomination of Directors and Confirmation of CEO and Chair

Although director nominees (other than the CEO) are required to be independent of both the Company and the Province pursuant to the Governance Agreement, there is a risk that the Province will nominate or confirm individuals who satisfy the independence requirements but who it considers are disposed to support and advance its policy objectives and give disproportionate weight to the Province’s interests in exercising their business judgment and balancing the interests of the stakeholders of Hydro One. This, combined with the fact certain matters require a two-thirds vote of the Board, could allow the Province to unduly influence certain Board actions such as confirmation of the Chair and confirmation of the CEO.

Board Removal Rights

Under the Governance Agreement, the Province has the right to withhold from voting in favour of all director nominees and has the right to seek to remove and replace the entire Board, including in each case its own director nominees but excluding the CEO and, at the Province’s discretion, the Chair. In exercising these rights in any particular circumstance, the Province is entitled to vote in its sole interest, which may not be aligned with the interests of other stakeholders of Hydro One.

More Extensive Regulation

Although under the Governance Agreement, the Province has agreed to engage in the business and affairs of Hydro One as an investor and not as a manager and has stated that its intention is to achieve its policy objectives through legislation and regulation as it would with respect to any other utility operating in Ontario, there is a risk that the Province will exercise its legislative and regulatory power to achieve policy objectives in a manner that has a material adverse effect on the Company. See “Risks Relating to Government Action” above.

Prohibitions on Selling the Company’s Transmission or Distribution Business

The Electricity Act prohibits the Company from selling all or substantially all of the business, property or assets related to its transmission system or distribution system that is regulated by the OEB. There is a risk that these prohibitions may limit the ability of the Company to engage in sale transactions involving a substantial portion of either system, even where such a transaction may otherwise be considered to provide substantial benefits to the Company and the holders of the common shares.

Future Sales of Common Shares by the Province

Although the Province has indicated that it does not intend to sell further common shares of Hydro One, the registration rights agreement between Hydro One and the Province dated November 5, 2015 (available on SEDAR at www.sedar.com) grants the Province the right to request that Hydro One file one or more prospectuses and take other procedural steps to facilitate secondary offerings by the Province of the common shares of Hydro One. Future sales of common shares of Hydro One by the Province, or the perception that such sales could occur, may materially adversely affect market prices for these common shares and impede Hydro One’s ability to raise capital through the issuance of additional common shares, including the number of common shares that Hydro One may be able to sell at a particular time or the total proceeds that may be realized.

Limitations on Enforcing the Governance Agreement

The Governance Agreement includes commitments by the Province restricting the exercise of its rights as a holder of voting securities, including with respect to the maximum number of directors that the Province may nominate and on how the Province will vote with respect to other director nominees. Hydro One’s ability to obtain an effective remedy against the Province, if the Province were not to comply with these commitments, is limited as a result of the Proceedings Against the Crown Act (Ontario). This legislation provides that the remedies of injunction and specific performance are not available against the Province, although a court may make an order declaratory of the rights of the parties, which may influence the Province’s actions. A remedy of damages would be available to Hydro One, but damages may not be an effective remedy, depending on the nature of the Province’s non-compliance with the Governance Agreement.

CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS

The preparation of Hydro One Consolidated Financial Statements requires the Company to make key estimates and critical judgments that affect the reported amounts of assets, liabilities, revenues and costs, and related disclosures of contingencies. Hydro One bases its estimates and judgments on historical experience, current conditions and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities, as well as identifying and assessing the Company’s accounting treatment with respect to commitments and contingencies. Actual results may differ from these estimates and judgments. Hydro One has identified the following critical accounting estimates used in the preparation of its Consolidated Financial Statements:

Revenues

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

estimated, and the corresponding unbilled revenue is recorded. The unbilled revenue estimate is affected by energy consumption, weather, and changes in the composition of customer classes.

Regulatory Assets and Liabilities

Hydro One’s regulatory assets represent certain amounts receivable from future electricity customers and costs that have been deferred for accounting purposes because it is probable that they will be recovered in future rates. The regulatory assets mainly include amounts related to the deferred income taxes, pension benefit liability, post-retirement and post-employment benefits, post-retirement and post-employment non-service costs, share-based compensation costs, foregone revenue, and environmental liabilities. The Company’s regulatory liabilities represent certain amounts that are refundable to future electricity customers. They pertain primarily to deferral and variance accounts. The regulatory assets and liabilities can be recognized for rate-setting and financial reporting purposes only if the amounts have been approved for inclusion in the electricity rates by the OEB, or if such approval is judged to be probable by management. If, at some future date, management judges that it is no longer probable that the OEB will allow the inclusion of a regulatory asset or liability in future electricity rates, the appropriate carrying amount would be reflected in results of operations prospectively from the date the Company’s assessment is made, unless the change meets the requirements for a subsequent event adjustment.

Environmental Liabilities

Hydro One records a liability for the estimated future expenditures associated with the removal and destruction of polychlorinated biphenyl (PCB)-contaminated insulating oils and related electrical equipment, and for the assessment and remediation of chemically contaminated lands. There are uncertainties in estimating future environmental costs due to potential external events such as changes in legislation or regulations and advances in remediation technologies. In determining the amounts to be recorded as environmental liabilities, the Company estimates the current cost of completing required work and makes assumptions as to when the future expenditures will actually be incurred, in order to generate future cash flow information. All factors used in estimating the Company’s environmental liabilities represent management’s best estimates of the present value of costs required to meet existing legislation or regulations. However, it is reasonably possible that numbers or volumes of contaminated assets, cost estimates to perform work, inflation assumptions and the assumed pattern of annual cash flows may differ significantly from the Company’s current assumptions. Environmental liabilities are reviewed annually or more frequently if significant changes in regulations or other relevant factors occur. Estimate changes are accounted for prospectively.

Employee Future Benefits

Hydro One’s employee future benefits consist of pension and post-retirement and post-employment plans, and include pension, group life insurance, health care, and long-term disability benefits provided to the Company’s current and retired employees. Employee future benefits costs are included in Hydro One’s labour costs that are either charged to results of operations or capitalized as part of the cost of property, plant and equipment and intangible assets. Changes in assumptions affect the benefit obligation of the employee future benefits and the amounts that will be charged to results of operations or capitalized in future years. The following significant assumptions and estimates are used to determine employee future benefit costs and obligations:

Weighted Average Discount Rate

The weighted average discount rate used to calculate the employee future benefits obligation is determined at each year end by referring to the most recently available market interest rates based on “AA”-rated corporate bond yields reflecting the duration of the applicable employee future benefit plan. The discount rate at December 31, 2019 decreased to 3.10% (from 3.90% at December 31, 2018) for pension benefits and decreased to 3.10% (from 4.00% at December 31, 2018) for the post-retirement and post-employment plans. The decrease in the discount rate has resulted in a corresponding increase in employee future benefits liabilities for the pension, post-retirement and post-employment plans for accounting purposes. The liabilities are determined by independent actuaries using the projected benefit method prorated on service and based on assumptions that reflect management’s best estimates.

Expected Rate of Return on Plan Assets

The expected rate of return on pension plan assets of 5.75% is based on expectations of long-term rates of return at the beginning of the year and reflects the current pension plan asset mix. A new investment policy was adopted by Hydro One effective May 14, 2018 and is being implemented over several years. Hydro One’s current expectation is that the new investment policy will not be fully implemented until 2021-2022. As such, with the implementation timing noted above, the actual asset mix as at November 1, 2019 is appropriate for the December 31, 2019 disclosures and the 2020 registered pension plan costs.

Rates of return on the respective portfolios are determined with reference to respective published market indices. The expected rate of return on pension plan assets reflects the Company’s long-term expectations. The Company believes that this assumption is reasonable because, with the pension plan’s balanced investment approach, the higher volatility of equity investment returns is intended to be offset by the greater stability of fixed-income and short-term investment returns. The net result, on a long-term basis, is a lower return than might be expected by investing in equities alone. In the short term, the pension plan can experience fluctuations in actual rates of return.

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

Rate of Cost of Living Increase

The rate of cost of living increase is determined by considering differences between long-term Government of Canada nominal bonds and real return bonds, which decreased from 1.40% per annum as at December 31, 2018 to approximately 1.30% per annum as at December 31, 2019. Given the Bank of Canada’s commitment to keep long-term inflation between 1.00% and 3.00%, management believes that the current rate is reasonable to use as a long-term assumption and as such, has used a 2.0% per annum inflation rate for employee future benefits liability valuation purposes as at December 31, 2019.

Salary Increase Assumptions

Salary increases should reflect general wage increases plus an allowance for merit and promotional increases for current members of the plan, and should be consistent with the assumptions for consumer price inflation and real wage growth in the economy. The merit and promotion scale was developed based on the salary increase assumption review performed in 2017. The review considers actual salary experience from 2002 to 2016 using valuation data for all active members as at December 31, 2016, based on age and service and Hydro One’s expectation of future salary increases. Additionally, the salary scale reflects negotiated salary increases over the contract period.

Mortality Assumptions

The Company’s employee future benefits liability is also impacted by changes in life expectancies used in mortality assumptions. Increases in life expectancies of plan members result in increases in the employee future benefits liability. The mortality assumption used at December 31, 2019 is 95% of 2014 Canadian Pensioners Mortality Private Sector table projected generationally using improvement Scale B.

Rate of Increase in Health Care Cost Trends

The costs of post-retirement and post-employment benefits are determined at the beginning of the year and are based on assumptions for expected claims experience and future health care cost inflation. For the post-retirement benefit plans, a trend study of historical Hydro One experience was conducted in 2017, which resulted in a change in the prescription drug, dental and hospital trends used for 2018 and 2019 year-end reporting purposes. A 1% increase in the health care cost trends would result in a $21 million increase in 2019 interest cost plus service cost, and a $280 million increase in the benefit liability at December 31, 2019.

Valuation of Deferred Tax Assets

Hydro One assesses the likelihood of realizing deferred tax assets by reviewing all readily available current and historical information, including a forecast of future taxable income. To the extent management considers it is more likely than not that some portion or all of the deferred tax assets will not be realized, a valuation allowance is recognized.

Asset Impairment

Within Hydro One’s regulated businesses, the carrying costs of most of the long-lived assets are included in the rate base where they earn an OEB-approved rate of return. Asset carrying values and the related return are recovered through OEB-approved rates. As a result, such assets are only tested for impairment in the event that the OEB disallows recovery, in whole or in part, or if such a disallowance is judged to be probable. The Company regularly monitors the assets of its unregulated Hydro One Telecom subsidiary for indications of impairment. As at December 31, 2019, no asset impairment had been recorded for assets within Hydro One’s regulated or unregulated businesses.

Goodwill is evaluated for impairment on an annual basis, or more frequently if circumstances require. Hydro One has concluded that goodwill was not impaired at December 31, 2019. Goodwill represents the cost of acquired distribution and transmission companies that is in excess of the fair value of the net identifiable assets acquired at the acquisition date.

DISCLOSURE CONTROLS AND PROCEDURES AND INTERNAL CONTROL OVER FINANCIAL REPORTING

Disclosure controls and procedures are the processes designed to ensure that information is recorded, processed, summarized and reported on a timely basis to the Company’s management, including its CEO and CFO, as appropriate, to make timely decisions regarding required disclosure in the MD&A and financial statements. At the direction of the Company’s CEO and CFO, management evaluated disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, management concluded that the Company’s disclosure controls and procedures were effective as at December 31, 2019.

Internal control over financial reporting is designed by, or under the direction of the CEO and CFO to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with US GAAP. The Company’s internal control over financial reporting framework includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and disposition of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with US GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorization of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or

33

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the Company’s consolidated financial statements.

The Company’s management, at the direction of the CEO and CFO, evaluated the effectiveness of the design and operation of internal control over financial reporting based on the criteria established in the Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that evaluation, management concluded that the Company’s internal control over financial reporting was effective as at December 31, 2019.

There were no changes in the design of the Company’s internal control over financial reporting during the three months ended December 31, 2019 that have materially affected, or are reasonably likely to materially affect, the operation of the Company’s internal control over financial reporting.

Management will continue to monitor its systems of internal control over reporting and disclosure and may make modifications from time to time as considered necessary.

Net Income

Net income attributable to common shareholders for the quarter ended December 31, 2019 of $211 million is an increase of $916 million or 129.9% from the prior year. Significant influences on earnings included:

•	higher revenues, net of purchased power, primarily resulting from the 2018 impact of the OEB decision in respect of the sharing of the deferred tax asset;
•	lower OM&A costs primarily resulting from lower corporate support costs and higher insurance proceeds, as well as the timing of work performed with respect to stations and lines maintenance and vegetation management compared to the prior year; partially offset by higher IT expenditures; and
---	---
•	lower income tax expense primarily attributable to the prior year charge to deferred tax expense related to the impairment of Hydro One's deferred income tax regulatory asset, as well as Accelerated CCA and deferred tax asset sharing mandated by the OEB, both of which will flow through to customers and are offset with lower revenues, with no impact on regulated ROE.

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

EPS and Adjusted EPS

EPS was $0.35 in the fourth quarter of 2019, compared to a loss per share of $1.18 in the fourth quarter of 2018. The increase in EPS was driven by higher earnings for the fourth quarter of 2019, as discussed above. Adjusted EPS was $0.35 in the fourth quarter of 2019, compared to $0.30 in the fourth quarter of 2018 which was driven by higher net income for the fourth quarter of 2019, but excluding the impacts of the Merger and the DTA Decision.

Revenues

The quarterly increase of $65 million or 19.0% in transmission revenues was primarily due to the following:

•	the 2018 impact of the OEB decision in respect of the sharing of the deferred tax asset;
•	increased OEB-approved transmission rates for 2019;
---	---
•	higher average monthly Ontario 60-minute peak demand driven by favourable weather in the fourth quarter of 2019; and
---	---
•	revenue related to NRLP assets placed in-service in late August 2019; partially offset by
---	---
•	deferred tax regulatory adjustment related to Accelerated CCA.
---	---

The quarterly decrease of $13 million or 3.3% in distribution revenues, net of purchased power, was primarily due to the following:

•	deferred regulatory adjustment related to Earnings Sharing Mechanism; and
•	deferred tax asset sharing mandated by the OEB and deferred tax regulatory adjustment related to Accelerated CCA; partially offset by
---	---
•	increased OEB-approved distribution rates for 2019; and
---	---
•	higher energy consumption resulting from favourable weather in the fourth quarter of 2019.
---	---

See section "Non-GAAP Measures" for description and reconciliation of revenues, net of purchased power.

OM&A Costs

The quarterly decrease of $55 million or 48.2% in transmission OM&A costs was primarily due to the following:

•	higher insurance proceeds received in the fourth quarter of 2019;
•	lower spend on station and lines maintenance programs;
---	---
•	lower volume of work on vegetation management coverage, as certain work was done earlier in 2019 as a result of favourable weather conditions;
---	---
•	lower corporate support costs;
---	---
•	lower project write-offs; and
---	---
•	lower property taxes due to a reassessment of municipal property taxes; partially offset by
---	---
•	higher spend related to IT projects.
---	---

The quarterly decrease of $5 million or 3.0% in distribution OM&A costs was primarily due to the following:

•	lower corporate support costs; and
•	lower operating costs resulting from the repatriation of the Call Centre; partially offset by
---	---
•	higher spend related to IT projects.
---	---

A further decrease of $9 million in other OM&A is driven primarily by lower support costs.

Financing Charges

The quarterly decrease of $7 million or 5.7% in financing charges was primarily due to lower Merger-related interest expense on the convertible debentures, partially offset by an increase in interest expense on long-term debt driven by higher weighted-average long-term debt balance outstanding in 2019.

Income Taxes

Income tax expense for the fourth quarter of 2019 decreased by $798 million compared to 2018. This resulted in a realized ETR of approximately 0.9% in the fourth quarter of 2019, compared to approximately 784.3% in the fourth quarter of the prior year. The lower tax expense was primarily attributable to the prior year charge to deferred tax expense related to the impairment of Hydro One's deferred income tax regulatory asset. Taxes were further lowered by the Accelerated CCA, deferred tax asset sharing mandated by the OEB, and changes in income before taxes in 2019 compared to 2018.

Assets Placed In-Service

The decrease in transmission assets placed in-service during the fourth quarter was primarily due to the following:

•	assets placed in-service in the fourth quarter of 2018 for station sustainment investments (Horning, Centralia, London, and St. Isidore transmission stations, as well as the Bruce Special Protection System end-of-life equipment replacement project); partially offset by
•	assets placed in-service for major development project at Leamington transmission station in 2019; and
---	---
•	higher volume of IT and work equipment purchases.

HYDRO ONE LIMITED

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)

For the years ended December 31, 2019 and 2018

The increase in distribution assets placed in-service during the fourth quarter was primarily due to the following:

•	higher volume of IT and work equipment purchases; and
•	higher volume of storm-related asset replacements in the fourth quarter of 2019.
---	---

Capital Investments

The increase in transmission capital investments during the fourth quarter was primarily due to the following:

•	higher volume of IT and work equipment purchases;
•	higher volume of transmission station refurbishments and replacements; and
---	---
•	higher investments in multi-year development projects in the fourth quarter of 2019 (primarily East-West Tie Expansion), partially offset by the work related to the Lake Superior Link project and completion of the Clarington transmission station in 2018.
---	---

The increase in distribution capital investments during the fourth quarter was primarily due to the following:

•	transfer of pension costs from the Pension Cost Differential regulatory account subsequent to the OEB’s decision on the motion to review and vary its decision as it relates to the recovery of pension costs;
•	higher investments in distribution system connections (Leamington and Enfield transmission stations) and increased investment in distribution modernization initiatives;
---	---
•	higher volume of IT and work equipment purchases; and
---	---
•	higher volume of storm-related asset replacements.

Words such as “expect”, “anticipate”, “intend”, “attempt”, “may”, “plan”, “will”, “believe”, “seek”, “estimate”, “goal”, “aim”, “target”, and variations of such words and similar expressions are intended to identify such forward-looking statements. These statements are not guarantees of future performance and involve assumptions and risks and uncertainties that are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed, implied or forecasted in such forward-looking statements. Hydro One does not intend, and it disclaims any obligation, to update any forward-looking statements, except as required by law.

These forward-looking statements are based on a variety of factors and assumptions including, but not limited to, the following: no unforeseen changes in the legislative and operating framework for Ontario’s electricity market or for Hydro One specifically; favourable decisions from the OEB and other regulatory bodies concerning outstanding and future rate and other applications; no unexpected delays in obtaining the required approvals; no unforeseen changes in rate orders or rate setting methodologies for the Company’s distribution and transmission businesses; continued use of US GAAP; a stable regulatory environment; no unfavourable changes in environmental regulation; no significant changes to the Company's current credit ratings; no unforeseen impacts of new accounting pronouncements; and no significant event occurring outside the ordinary course of business. These assumptions are based on information currently available to the Company, including information obtained from third-party sources. Actual results may differ materially from those predicted by such forward-looking statements. While Hydro One does not know what impact any of these differences may have, the Company’s business, results of operations, financial condition and credit stability may be materially adversely affected. Factors that could cause actual results or outcomes to differ materially from the results expressed or implied by forward-looking statements include, among other things:

•	regulatory risks and risks relating to Hydro One’s revenues, including risks relating to rate orders and the rate-setting models for transmission and distribution, actual performance against forecasts and capital expenditures, the regulatory treatment of the deferred tax asset, the recoverability of total compensation costs or denials of applications;
•	risks associated with the Province’s share ownership of Hydro One and other relationships with the Province, including potential conflicts of interest that may arise between Hydro One, the Province and related parties, risks associated with the Province’s exercise of further legislative and regulatory powers in the implementation of the Hydro One Accountability Act, risks relating to the ability of the Company to attract and retain qualified executive talent or the risk of a credit rating downgrade for Hydro One Inc. and its impact on the Company’s funding and liquidity;
---	---
•	risks relating to the location of the Company’s assets on Reserve lands and the risk that Hydro One may incur significant costs associated with transferring assets located on Reserves;
---	---
•	the risk that the Company may be unable to comply with regulatory and legislative requirements or that the Company may incur additional costs for compliance that are not recoverable through rates;
---	---
•	the risk of exposure of the Company’s facilities to the effects of severe weather conditions, natural disasters, man-made events or other unexpected occurrences for which the Company is uninsured or for which the Company could be subject to claims for damage;
---	---
•	the risk of non-compliance with environmental regulations and inability to recover environmental expenditures in rate applications;
---	---
•	risks associated with information system security and maintaining complex IT and OT system infrastructure, including system failures or risks of cyber-attacks or unauthorized access to corporate IT and OT systems;
---	---
•	the risk of labour disputes and inability to negotiate or renew appropriate collective agreements on acceptable terms consistent with the Company’s rate decisions;
---	---
•	risks related to the Company’s work force demographic and its potential inability to attract and retain qualified personnel;
---	---
•	the risk that the Company is not able to arrange sufficient cost-effective financing to repay maturing debt and to fund capital expenditures;
---	---
•	risks associated with fluctuations in interest rates and failure to manage exposure to credit and financial instrument risk;
---	---
•	risks associated with economic uncertainty and financial market volatility;
