Industry and Market Data
Industry and market data used throughout this report were obtained through internal research, surveys and studies conducted by unrelated third parties and publicly available industry and general publications. We have not independently verified market and industry data from external sources. While we believe internal partnership estimates are reliable and market definitions are appropriate, neither such estimates nor these definitions have been verified by any independent sources.
ii
Production Capacity
Unless we state otherwise, annual production capacity estimates used throughout this report represent rated capacity of the facilities at December 31, 2024. We calculated rated capacity by estimating the number of days in a typical year that a production unit of a plant is expected to operate, after allowing for downtime for regular maintenance, and multiplying that number by an amount equal to the unit's optimal daily output based on the design feedstock mix. Because the rated capacity of a production unit is an estimated amount, actual production volumes may be more or less than the rated capacity.

PART I
Item 1. Business
General
We are a Delaware limited partnership formed by Westlake in March 2014 to operate, acquire and develop ethylene production facilities and related assets. On August 4, 2014, we completed our initial public offering (the "IPO") of 12,937,500 common units representing limited partner interests. In connection with the IPO, we acquired an initial 10.6% interest in OpCo and a 100% interest in OpCo GP, which is the general partner of OpCo. As of December 31, 2018, we had an aggregate 18.3% limited partner interest in OpCo. On March 29, 2019, we completed a private placement of 2,940,818 common units and used the net proceeds to purchase an additional 4.5% interest in OpCo, effective January 1, 2019, resulting in us owning an aggregate 22.8% limited partner interest in OpCo.
Our business and operations are conducted through OpCo. Because we own OpCo's general partner, we have control over all of OpCo's assets and operations. As of December 31, 2024, Westlake held a 77.2% limited partner interest in OpCo and held a 40.1% limited partner interest in us (consisting of 14,122,230 common units), our general partner interest and our incentive distribution rights.
OpCo's assets are comprised of three ethylene production facilities, which primarily convert ethane into ethylene and have an aggregate annual capacity of approximately 3.7 billion pounds, and a 200-mile ethylene pipeline. OpCo derives substantially all of its revenue from these ethylene production facilities. Ethylene is the world's most widely used petrochemical in terms of volume and is a key building block used to produce a number of key derivatives, such as polyethylene ("PE") and polyvinyl chloride ("PVC"), which are used in a wide variety of end markets, including packaging, construction and transportation. Westlake's downstream PE and PVC production facilities consume a substantial majority of the ethylene produced by OpCo. OpCo generates revenue primarily by selling ethylene to Westlake and others, as well as through the sale of co-products of ethylene production, including propylene, crude butadiene, pyrolysis gasoline and hydrogen. Our sole revenue generating asset is our 22.8% limited partner interest in OpCo.
Our assets and operations are organized into a single reportable segment and are all located and conducted in the United States. See "Item 8. Financial Statements and Supplementary Data" for financial information on our operations and assets; such information is incorporated herein by reference.
Among other agreements entered into in connection with the closing of the IPO, OpCo entered into an ethylene sales agreement with Westlake with an initial term of 12 years, under which Westlake agreed to purchase 95% of OpCo's planned ethylene production each year, on a cost-plus basis that is expected to generate a fixed margin per pound of $0.10 (the "Ethylene Sales Agreement"). Any ethylene not sold to Westlake and all co-products that are produced by OpCo will be sold to third parties on either a spot or contract basis. OpCo also entered into a feedstock supply agreement with Westlake that supplies OpCo with ethane (and any other feedstocks) required for OpCo to produce ethylene under the Ethylene Sales Agreement (the "Feedstock Supply Agreement"). OpCo primarily uses ethane (a component of natural gas liquids, or NGLs) to produce ethylene.

Our Assets and Operations
Our sole revenue generating asset is our 22.8% limited partner interest in OpCo. We also own the general partner interest of OpCo. OpCo owns:
•two ethylene production facilities at Westlake's Lake Charles, Louisiana site ("Petro 1" and "Petro 2," collectively referred to as "Lake Charles Olefins"), with an annual combined capacity of approximately 3.0 billion pounds;
•one ethylene production facility at Westlake's Calvert City, Kentucky site ("Calvert City Olefins"), with an annual capacity of approximately 730 million pounds; and
•a 200-mile common carrier ethylene pipeline that runs from Mont Belvieu, Texas to the Longview, Texas chemical site, which includes Westlake's Longview PE production facility (the "Longview Pipeline").
As the owner of the general partner interest of OpCo, we control all aspects of the management of OpCo, including its cash distribution policy. See "—OpCo's Assets."
OpCo's Assets
Ethylene Production Facilities
OpCo operates three ethylene production facilities that are situated on real property leased to OpCo by Westlake pursuant to two 50-year site lease agreements. See "Our Agreements with Westlake—Site Lease Agreements" for a description of the site leases. Ethylene can be produced from either NGL feedstocks, such as ethane, propane and butane, or from petroleum-derived feedstocks, such as naphtha. Lake Charles Olefins and Calvert City Olefins use primarily ethane as their feedstock. Calvert City Olefins can also use propane as a feedstock and Petro 2 can also use an ethane/propane mix, propane, butane or naphtha as a feedstock.
The following table provides information regarding OpCo's ethylene production facilities as of December 31, 2024:
| Plant Location (Description) | Annual Production Capacity (millions of pounds) | Feedstock | Primary Uses of Ethylene | ||||||||||||||||||||
| Lake Charles, Louisiana (Petro 1) | 1,500 | Ethane | PE and PVC | ||||||||||||||||||||
| Lake Charles, Louisiana (Petro 2) | 1,490 | Ethane, ethane/propane mix, propane, butane or naphtha | PE and PVC | ||||||||||||||||||||
| Calvert City, Kentucky (Calvert City Olefins) | 730 | Ethane or propane | PVC | ||||||||||||||||||||
| Total | 3,720 | ||||||||||||||||||||||
Lake Charles Olefins
Two of OpCo's ethylene production facilities, which we refer to as Petro 1 and Petro 2 and, collectively, as Lake Charles Olefins, are located at Westlake's Lake Charles site. The combined capacity of these two ethylene production facilities is approximately 3.0 billion pounds per year.
Within Westlake's Lake Charles site, Petro 1 and Petro 2 are connected by pipeline systems to Westlake's polyethylene plants. Westlake may use the ethylene it purchases from OpCo at its Lake Charles facilities or transfer it to its Geismar facility or its Longview facility, either through physical transportation or via exchange transactions. Westlake may also use the ethylene it purchases from OpCo with chlorine to produce ethylene dichloride and transport it via barge to Westlake's Calvert City site.
In addition, OpCo produces ethylene co-products including chemical grade propylene, crude butadiene, pyrolysis gasoline and hydrogen. OpCo sells its output of these co-products to external customers.
Calvert City Olefins
One of OpCo's ethylene production facilities is located at Westlake's Calvert City site, which we refer to as Calvert City Olefins. The capacity of Calvert City Olefins is approximately 730 million pounds per year.
3
Pipeline
OpCo owns a 200-mile 10-inch diameter ethylene pipeline system that connects the Equistar Pipeline, the Flint Hills Pipeline and the Lone Star Storage Facility in Mont Belvieu to the Longview, Texas chemical site, which includes Westlake's Longview PE production facility. The system has a capacity of 3.5 million pounds per day of ethylene and is operated as a common carrier pipeline by Buckeye Development & Logistics I LLC. As a common carrier intrastate pipeline in Texas, the system is subject to rate regulation under the Texas Utilities Code, as implemented by the Texas Railroad Commission, or the TRRC, and has a tariff on file with the TRRC.
Technology
OpCo has perpetual and paid-up licenses for steam cracking and process recovery technology used at its ethylene plants.
Our Agreements with Westlake
Except as otherwise indicated, the agreements described below became effective on August 4, 2014, concurrent with the closing of the IPO.
Ethylene Sales Agreement
OpCo and Westlake are parties to the Ethylene Sales Agreement, which has an initial term through December 31, 2026 and automatic 12-month renewal periods until terminated at the end of the initial term or any renewal term on 12-months' notice. The Ethylene Sales Agreement requires Westlake to purchase OpCo's planned ethylene production each year, subject to certain exceptions and a maximum commitment of 3.8 billion pounds per year, less product sold by OpCo to third parties equal to approximately 5% of the annual output. Westlake's purchase price for its minimum commitment of ethylene under the Ethylene Sales Agreement includes a $0.10 per pound margin, the total costs incurred by OpCo for the feedstock and natural gas to produce each pound of ethylene (subject to a usage cap and a floor), and estimated operating costs, maintenance capital expenditures and other turnaround expenditures, less net proceeds from co-products sales. This purchase price is not designed to cover capital expenditures for expansion. Variable costs not incurred by OpCo due to a deficiency in purchases by Westlake are rebated to Westlake. Under specified circumstances, unrecovered costs may be carried forward for recovery in subsequent years. If OpCo's actual production is in excess of planned ethylene production, Westlake has the option to purchase up to 95% of production in excess of planned production. The price for the sale of such excess ethylene to Westlake is based on a formula similar to that used for the minimum purchase commitment, with the exception of certain fixed costs.
Certain of the pricing components that make up the price for ethylene sold under the Ethylene Sales Agreement are modified to reflect the portion of OpCo's production capacity that is used to process Westlake's purge gas instead of producing ethylene. Costs specific to the processing of Westlake's purge gas are recovered under the Services and Secondment Agreement (as described below), and not the Ethylene Sales Agreement.
Under the Ethylene Sales Agreement, OpCo has the option to curtail up to approximately 5% of its ethylene production annually in the event OpCo reasonably determines that its sales of such ethylene to third parties during the relevant period would be uneconomic.
Pursuant to the Ethylene Sales Agreement, Westlake's obligation to pay for the annual minimum commitment (95% of OpCo's budgeted ethylene production), which is measured on an annual basis, is not reduced for a force majeure event lasting fewer than 45 consecutive days. In the event of a force majeure event, the Partnership recognizes buyer deficiency fees representing fixed margin and unavoided operating and maintenance capital expenditures and maintenance expenses per pound of volume committed by Westlake during the force majeure period. In the event Westlake purchases less than its annual commitment, we recognize buyer deficiency fees representing fixed margin and all expenses and expenditures incurred per pound of volume committed but not taken by Westlake. Payment for the buyer deficiency fee is scheduled to be received by the Partnership after the conclusion of the year in which the force majeure event occurred.
Under the Ethylene Sales Agreement, if production costs billed to Westlake on an annual basis are less than 95% of the actual production costs incurred by OpCo during the contract year, OpCo is entitled to recover the shortfall in such production costs (proportionate to the volume sold to Westlake) in the subsequent year ("Shortfall"). The Shortfall is generally recognized during the period in which the related operating, maintenance or turnaround activities occur.
The Ethylene Sales Agreement provides that, if compliance with any law adopted or modified following our IPO results in OpCo incurring additional costs in excess of $500,000 in any contract year, OpCo is entitled to charge Westlake a monthly surcharge following efforts to mitigate the effects of such compliance.
4
Feedstock Supply Agreement
OpCo and Westlake are parties to the Feedstock Supply Agreement, which has an initial term through December 31, 2026 and automatic 12-month renewal periods until terminated at the end of the initial term or any renewal term on 12-months' notice. Under the Feedstock Supply Agreement, Westlake sells OpCo ethane and other feedstock in amounts sufficient for OpCo to produce the ethylene to be sold under the Ethylene Sales Agreement. The price at which ethane and feedstock is sold includes an indexed price for spot gas liquids at Mont Belvieu and applicable transportation, storage and other costs.
Services and Secondment Agreement
OpCo and Westlake are parties to the Services and Secondment Agreement, pursuant to which OpCo provides Westlake with various utilities and utility services in exchange for Westlake providing OpCo with various utility services, comprehensive operating services for OpCo's units, services for the maintenance and operation of the common facilities and seconded employees to perform all services required under the agreement.
Site Lease Agreements
OpCo and Westlake are parties to two 50-year site lease agreements (the "Site Leases"). Under the Site Leases, OpCo leases the real property underlying Calvert City Olefins and Lake Charles Olefins and is granted certain use and access rights related thereto, for a base rental amount of $1 per year per site. Each of the Site Leases is terminable by the lessor upon the occurrence of certain events of default or by OpCo if Calvert City Olefins or Lake Charles Olefins, as applicable, is destroyed by casualty. Pursuant to the Site Leases, Westlake has the right to restore and repurchase the units for fair market value if OpCo fails to expeditiously restore Calvert City Olefins or Lake Charles Olefins, as applicable, following a casualty loss. Subject to the foregoing repurchase right, OpCo may remove its ethylene production facilities and other related improvements for up to one year after expiration or termination of the applicable Site Lease, so long as such removal can be accomplished without material damage or harm to Westlake's property or operations and provided that any assets that are not timely removed by OpCo will be deemed to have been surrendered to Westlake.
Omnibus Agreement
We, OpCo and Westlake are parties to the Omnibus Agreement, pursuant to which we granted Westlake, among other things, a right of first refusal on any proposed transfer of (1) our equity interests in OpCo, (2) the ethylene production facilities that serve Westlake's other facilities or (3) certain other assets we may acquire from Westlake. The Omnibus Agreement also provides for reimbursement to Westlake for the provision of various administrative services and direct expenses incurred on our behalf and in connection with the operation of our business. Under the Omnibus Agreement, Westlake will indemnify us against certain environmental and other losses, and we will indemnify Westlake against certain environmental and other losses for which Westlake is not otherwise obligated to indemnify us and certain other losses and liabilities to the extent resulting from the provision of services by Westlake to us.
Exchange Agreement
OpCo and Westlake are parties to an exchange agreement, which had an initial term through August 1, 2015 and continues on an annual basis unless and until terminated by either party. Under the exchange agreement, OpCo may require Westlake to deliver up to 200 million pounds of ethylene for OpCo per year from the Site Leases to an ethylene hub in Mont Belvieu, Texas, for which OpCo would be required to pay Westlake an exchange fee of $0.006 per pound.
OpCo Partnership Agreement
We, OpCo GP and Westlake are parties to an agreement of limited partnership for OpCo (the "OpCo LP Agreement"). The OpCo LP Agreement governs the ownership and management of OpCo and designates OpCo GP as the general partner of OpCo. OpCo GP generally has complete authority to manage OpCo's business and affairs. We control OpCo GP, as its sole member, subject to certain approval rights held by Westlake.
5
Investment Management Agreement
On August 1, 2017, we, OpCo and Westlake executed an Investment Management Agreement that authorizes Westlake to invest the Partnership's and OpCo's excess cash with Westlake for durations of up to a maximum of nine months. Per the terms of the Investment Management Agreement, the Partnership earns a market return plus five basis points and Westlake provides daily availability of the invested cash to meet any liquidity needs of the Partnership or OpCo.
See "Liquidity and Capital Resources" in Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" for a discussion of the Partnership's and OpCo's debt agreements with Westlake and "Interest Rate Risk" in Item 7A. "Quantitative and Qualitative Disclosures about Market Risk" for a discussion of the Partnership's interest rate contract with Westlake.
Environmental
As is common in our industry, we and OpCo are subject to environmental laws and regulations related to the use, storage, handling, generation, transportation, emission, discharge, disposal and remediation of, and exposure to, hazardous and non-hazardous substances and wastes in all of the jurisdictions in which we do business. National, state or provincial and local standards regulating air, water and land quality affect substantially all of our manufacturing locations. Compliance with such laws and regulations has required and will continue to require capital expenditures and increased operating costs. Pursuant to our arrangement with Westlake, Westlake will indemnify us for liabilities that occurred or existed (in connection with compliance with such laws and regulations) prior to August 4, 2014.
It is our policy to comply with all environmental, health and safety requirements in the jurisdictions in which we and OpCo operate and to provide safe and environmentally sound workplaces for our employees. In some cases, compliance can be achieved only by incurring capital expenditures. In 2024, OpCo incurred capital expenditures of $3.5 million related to environmental compliance. We estimate that OpCo will make capital expenditures of approximately $3.6 million in 2025 and $3.6 million in 2026, respectively, related to environmental compliance. We anticipate that stringent environmental regulations will continue to be imposed on us and the industry in general. Under the Ethylene Sales Agreement, we may be entitled to charge Westlake a monthly surcharge as a result of complying with certain changes in law occurring after our IPO. See "Business—Our Agreements with Westlake—Ethylene Sales Agreement." Although we cannot predict with certainty future expenditures, management believes that our current spending trends for environmental compliance will continue.
Also, see the discussion of our environmental matters contained in "Item 1A. Risk Factors" and "Item 3. Legal Proceedings" below.
Human Capital
Neither we nor OpCo has any employees. Under the Services and Secondment Agreement with Westlake, Westlake seconds employees to OpCo to allow OpCo to operate its facilities, and we sometimes refer to these individuals, for drafting convenience only, as our employees because they provide services directly to us. Such seconded employees are under OpCo's control while they work on OpCo's facilities. As of December 31, 2024, 153 employees of Westlake were seconded to OpCo. Of these, 25 are covered by collective bargaining agreements. On November 1, 2024, bargaining unit employees of Local Lodge No. 2781 of the International Association of Machinists and Aerospace Workers ("IAM") began a strike at our Calvert City, Kentucky, facility, after the IAM members, who work in the OpCo's ethylene facility and Westlake's chlorine units, did not accept Westlake's final offer for a new collective bargaining agreement. The ethylene unit continued to operate without disruption with the use of management and other salaried personnel. The strike ended on November 8, 2024, after the IAM accepted Westlake's offer for a new collective bargaining agreement, which will expire on November 9, 2029. Despite the recent strike, we believe that Westlake's relationship with local union officials and bargaining committees is open and positive. Westlake is responsible for human capital management policies, including any human capital measures and objectives that management focuses on in managing the business.
Legal Proceedings
In the ordinary conduct of our business, we and Westlake and our and Westlake's subsidiaries, including OpCo, are subject to lawsuits, investigations and claims, including environmental claims and employee related matters. Although we cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against us, we do not believe that any currently pending legal proceeding or proceedings to which we or Westlake or any of our or Westlake's subsidiaries, including OpCo, are a party will have a material adverse effect on our business, results of operations, cash flows or financial condition.
6
Competition
Due to the Ethylene Sales Agreement and integration with Westlake, OpCo does not directly compete with other ethylene producers for 95% of the planned volumes it produces. It is only on the 5% of planned ethylene volumes and any excess volumes not sold to Westlake where OpCo competes with other regional merchant ethylene producers, including LyondellBasell Industries, N.V., Shell Chemical Company, BASF Corporation and Motiva Enterprises LLC.

Item 1A. Risk Factors
Limited partner interests are inherently different from the capital stock of a corporation, although many of the business risks to which we are subject are similar to those that would be faced by a corporation engaged in a similar business. Security holders and potential investors should carefully consider the following risk factors together with all of the other information included in this report. If any of the following risks were actually to occur, our business, financial condition, results of operations or cash flows could be materially adversely affected.
Risk Factor Summary
Risks Inherent in Our Business
Operational Relationship with Westlake
•We are substantially dependent on Westlake for our cash flows. If Westlake does not pay us under the terms of the Ethylene Sales Agreement or if our assets fail to perform as intended, we may not have sufficient cash from operations following the establishment of cash reserves and payment of costs and expenses, including cost reimbursements to our general partner and its affiliates, to enable us to pay the minimum quarterly distribution to our unitholders.
•OpCo is subject to the credit risk of Westlake on a substantial majority of its revenues, and Westlake's leverage and creditworthiness could adversely affect our ability to make distributions to our unitholders.
•OpCo is a restricted subsidiary under certain indentures governing Westlake's senior notes.
•The ethylene sales price charged under the Ethylene Sales Agreement is designed to permit OpCo to cover the substantial majority of its operating costs, but not our public partnership, debt and other OpCo costs, which reduce our net operating profit.
•If OpCo is unable to renew or extend the Ethylene Sales Agreement beyond the initial 12-year term or the other agreements with Westlake upon expiration of these agreements, our ability to make distributions in the future could be materially adversely affected and the value of our units could decline.
•OpCo has the right to use the real property underlying Lake Charles Olefins and Calvert City Olefins pursuant to two, 50-year site lease agreements with Westlake. If OpCo is not able to renew the site lease agreements or if the site lease agreements are terminated by Westlake, OpCo may have to relocate Lake Charles Olefins and Calvert City Olefins, abandon the assets or sell the assets to Westlake.
•OpCo depends upon Westlake for numerous services and for its labor force.
•Cost reimbursements due to our general partner and Westlake for services provided to us or on our behalf reduce our earnings and therefore our cash available for distribution to our unitholders. The amount and timing of such reimbursements are determined by our general partner.
7
Business Operations
•Substantially all of OpCo's sales are generated at three facilities located at two sites. Any adverse developments at any of these facilities or sites could have a material adverse effect on our results of operations and therefore our ability to distribute cash to unitholders.
•The amount of cash we have available for distribution to holders of our units depends primarily on our cash flow and not solely on profitability, which may prevent us from making cash distributions during periods when we record net income.
•If we are unable to make acquisitions from Westlake or third parties on economically acceptable terms, our future growth would be limited, and any acquisitions we make may reduce, rather than increase, our cash generated from operations on a per unit basis.
•Our operations and assets are subject to climate-related risks and uncertainties.
•Our variable-rate debt exposes us to increases in interest rates, which could have a material impact on our financial position, results of operation and cash flows, and could reduce the price at which our common units trade.
•The impact and effects of public health crises, pandemics and epidemics could materially adversely affect OpCo's business, financial condition and results of operations.
Risks Relating to Our Partnership Structure
Our General Partner
•Westlake owns and controls our general partner, which has sole responsibility for conducting our business and managing our operations. Our general partner and its affiliates, including Westlake, may have conflicts of interest with us and have limited duties, and they may favor their own interests to our detriment and that of our unitholders.
•Our general partner has limited its liability regarding our obligations.
•Our partnership agreement replaces our general partner's fiduciary duties to holders of our units.
•Westlake and other affiliates of our general partner may compete with us.
•Holders of our common units have limited voting rights and are not entitled to elect our general partner or its directors, which could reduce the price at which our common units trade.
•Even if holders of our common units are dissatisfied, they cannot currently remove our general partner without its consent.
•Control of our general partner may be transferred to a third party without unitholder consent.
•Our general partner has a call right that may require unitholders to sell their common units at an undesirable time or price.
Cash Distributions to Unitholders
•The board of directors may modify or revoke our cash distribution policy at any time at its discretion. Our partnership agreement does not require us to pay any distributions at all.
•We expect to distribute a significant portion of our available cash to our partners, which could limit our ability to grow and make acquisitions.
Ownership of Our Common Units
•We may issue additional units without unitholder approval, which would dilute existing unitholder ownership interests.
•The market price of our common units could be adversely affected by sales of substantial amounts of our common units in the public or private markets, including sales by Westlake or other large holders.
8
Tax Risks
•Our tax treatment depends on our status as a partnership for U.S. federal income tax purposes, and not being subject to a material amount of entity-level taxation. Our cash available for distribution to unitholders may be substantially reduced if we become subject to entity-level taxation as a result of the Internal Revenue Service ("IRS") treating us as a corporation or legislative, judicial or administrative changes, and may also be reduced by any audit adjustments if imposed directly on the partnership.
•Even if unitholders do not receive any cash distributions from us, unitholders will be required to pay taxes on their share of our taxable income. A unitholder's share of our taxable income may be increased as a result of the IRS successfully contesting any of the U.S. federal income tax positions we take.
•Tax-exempt entities and non-U.S. unitholders face unique tax issues from owning our common units that may result in adverse tax consequences to them.
Risks Inherent in Our Business
Operational Relationship with Westlake
We are substantially dependent on Westlake for our cash flows. If Westlake does not pay us under the terms of the Ethylene Sales Agreement or if our assets fail to perform as intended, we may not have sufficient cash from operations following the establishment of cash reserves and payment of costs and expenses, including cost reimbursements to our general partner and its affiliates, to enable us to pay the minimum quarterly distribution to our unitholders.
Currently, all of our cash flow is generated from cash distributions from OpCo, and a substantial majority of OpCo's cash flow is generated from payments by Westlake under the Ethylene Sales Agreement. Westlake's obligations to purchase ethylene under the Ethylene Sales Agreement may be temporarily suspended to the extent OpCo is unable to perform its obligations caused by certain events outside the reasonable control of OpCo. Such events include, for example, acts of God or calamities which affect the operation of OpCo's facilities; certain labor difficulties (whether or not the demands of the employees are within the power of OpCo to concede); and governmental orders or laws. In addition, Westlake is not obligated to purchase ethylene with respect to any period during which OpCo's facilities are not operating due to scheduled or unscheduled maintenance or turnarounds other than under certain circumstances relating to the occurrence of force majeure. We expect that each of OpCo's facilities will have a turnaround approximately once every five to eight years and will not operate for typically between 30 and 60 days during each separate turnaround. However, the duration of any turnaround activities may be longer than expected or may cost more than originally estimated. Furthermore, facility expansions may also coincide with turnarounds, which may complicate and delay the completion of such turnarounds. A suspension of Westlake's obligations under the Ethylene Sales Agreement, including during periods where OpCo's facilities are not operating due to scheduled or unscheduled maintenance or turnarounds, would reduce OpCo's revenues and cash flows, and could materially adversely affect our ability to make distributions to our unitholders.
9
Westlake may be unable to generate enough cash flow from operations to meet its minimum obligations under the Ethylene Sales Agreement if its business is adversely impacted by competition, operational problems, international trade barriers, general adverse economic conditions or the inability to obtain feedstock. For example, lower prices of crude oil could lead to a reduction in the cost advantage for natural gas liquids-based ethylene derivatives in North America, such as Westlake's, as compared to naphtha-based ethylene derivatives. Additionally, Westlake operates internationally and could be adversely affected by trade barriers, tariffs and duties, or violations of international fair trade laws by global competitors. As a result, Westlake's margins and cash flows could be negatively impacted during such period. If Westlake is not able to meet its minimum payment obligations to OpCo as a result of any one or more of these factors, our ability to make distributions to our unitholders would be reduced or eliminated. The amount paid by Westlake will depend upon its ability to satisfy its minimum obligations under the Ethylene Sales Agreement and its ability and election to increase volumes above the minimums specified in the Ethylene Sales Agreement, which in turn are dependent upon, among other things, the level of polyethylene and polyvinyl chloride production at Westlake's other facilities, as well as industry capacity expansion in these downstream products in North America, a number of which have been recently completed. If Westlake is unable to generate sufficient cash flow from its operations to meet its obligations, or otherwise defaults on its obligations, under the Ethylene Sales Agreement, OpCo will not have sufficient available cash to distribute to us to enable us to pay the minimum quarterly distribution set forth in our cash distribution policy. As a result, our ability to pay the minimum quarterly distribution is based on the following factors, some of which are beyond our control:
•severe financial hardship or bankruptcy of Westlake or one of our other customers, or the occurrence of other events affecting our ability to collect payments from Westlake or our other customers, including any of our customers' default;
•volatility and cyclical downturns in the chemicals industry and other industries which materially and adversely impact Westlake and our other customers;
•Westlake's inability to perform, or any other default on its obligations, under the Ethylene Sales Agreement, the Services and Secondment Agreement and the Omnibus Agreement;
•the age of, and changes in the reliability, efficiency and capacity of the various equipment and operating facilities used in OpCo's operations, and in the operations of Westlake and our other customers, business partners and/or suppliers;
•the cost of environmental remediation at OpCo's facilities not covered by Westlake or third parties;
•changes in the expected operating levels of OpCo's assets;
•OpCo's ability to meet minimum volume requirements, yield standards and ethylene quality requirements in the Ethylene Sales Agreement;
•OpCo's ability to renew the Ethylene Sales Agreement or to enter into new, long-term agreements for the sale of ethylene under terms that are similar or more favorable;
•changes in the marketplace that may affect supply and demand for ethane or ethylene, including decreased availability of ethane (which may result from greater restrictions on hydraulic fracturing, any reduction in hydraulic fracturing due to low crude oil prices or exports of natural gas liquids from the United States, for example), increased production of ethylene (a number of new ethylene capacity expansions have been recently completed) or export of ethane or ethylene from the United States;
•changes in overall levels of production, production capacity, pricing and/or margins for ethylene;
•OpCo's ability to secure adequate supplies of ethane, other feedstocks and natural gas from Westlake or third parties;
•the need to use higher priced or less attractive feedstock due to the unavailability of ethane;
•the effects of pipeline, railroad, barge, truck and other transportation performance and costs, including any transportation disruptions;
•the effects of inflation and fluctuations in interest rates;
•the availability and cost of labor;
•risks related to employees and workplace safety;
•the effects of adverse events relating to the operation of OpCo's facilities and to the transportation and storage of hazardous materials (including equipment malfunction, explosions, fires, spills and the effects of severe weather conditions);
•changes in product specifications for the ethylene that we produce;
•changes in insurance markets and the level, types and costs of coverage available, and the financial ability and willingness of our insurers to meet their obligations;
10
•changes in, or new, statutes, regulations or governmental policies by federal, state and local authorities with respect to protection of the environment;
•changes in accounting rules and/or tax laws or their interpretations;
•nonperformance or force majeure by, or disputes with or changes in contract terms with, Westlake, our other major customers, suppliers, dealers, distributors or other business partners; and
•changes in, or new, statutes, regulations, governmental policies and taxes, or their interpretations.
In addition, the actual amount of cash we will have available for distribution will depend on other factors, including:
•the amount of cash we or OpCo are able to generate from sales of ethylene, and associated co-products, to third parties, which will be impacted by changes in prices for ethane (or other feedstocks), natural gas, ethylene and co-products and lower prices of crude oil, new ethylene capacity expansions in North America (a number of which have been completed recently), and could be less than the margin we earn from ethylene sales to Westlake;
•the level of capital expenditures we or OpCo make;
•the cost of acquisitions;
•construction costs;
•fluctuations in our or OpCo's working capital needs;
•our or OpCo's ability to borrow funds (including under our or OpCo's revolving credit facilities) and access capital markets;
•our or OpCo's debt service requirements, including interest owed on variable rate debt, and other liabilities;
•restrictions contained in our or OpCo's existing or future debt agreements; and
•the amount of cash reserves established by our general partner.
We will require a significant amount of cash to service our debt and OpCo's debt, including borrowings under our and OpCo's credit facilities with Westlake. Our ability to make payments on and refinance this debt will depend on our ability to generate cash in the future, which is subject to the same factors described above in connection with our ability to pay quarterly distributions to unitholders. Cash that is used to service debt will be unavailable for distributions to our unitholders.
OpCo is subject to the credit risk of Westlake on a substantial majority of its revenues, and Westlake's leverage and creditworthiness could adversely affect our ability to make distributions to our unitholders.
Our ability to make distributions to unitholders is substantially dependent on Westlake's ability to meet its minimum contractual obligations under the Ethylene Sales Agreement and its obligations under the Services and Secondment Agreement and the Omnibus Agreement. If Westlake defaults on its obligations, our ability to make distributions to our unitholders would be reduced or eliminated. Westlake has not pledged any assets to us as security for the performance of its obligations.
Westlake has not agreed with us to limit its ability to incur indebtedness, pledge or sell assets or make investments, and we have no control over the amount of indebtedness Westlake incurs, the assets it pledges or sells or the investments it makes.
OpCo is a restricted subsidiary under certain indentures governing Westlake's senior notes.
All of our cash is currently generated from cash distributions from OpCo. Certain indentures governing Westlake's senior notes impose significant operating and financial restrictions on OpCo. These restrictions limit OpCo's ability to:
•incur additional indebtedness;
•create liens; and
•sell all or substantially all of its assets or consolidate or merge with or into other companies.
These covenants may adversely affect OpCo's ability to finance future business opportunities. A breach of any of these covenants could result in a default in respect of the related debt. If a default occurred, the relevant lenders could elect to declare the debt, together with accrued interest and other fees, to be immediately due and payable and proceed against any collateral securing that debt, including OpCo and its assets. In addition, any acceleration of debt under Westlake's credit facility will constitute a default under some of Westlake's other debt, including the indentures governing its senior notes.
11
The ethylene sales price charged under the Ethylene Sales Agreement is designed to permit OpCo to cover the substantial majority of its operating costs, but not our public partnership, debt and other OpCo costs, which reduce our net operating profit.
The purchase price under the Ethylene Sales Agreement is based on OpCo's actual ethane, other feedstock and natural gas costs and an annual estimate of other operating costs and maintenance capital expenditures and other turnaround expenditures. The price is designed to permit OpCo to recover the portion of its costs of feedstocks and other costs to operate the ethylene production facilities associated with the percentage of its production capacity purchased by Westlake and generate a fixed margin per pound of ethylene purchased by Westlake. The price is not designed to allow OpCo to recover any capital expenditures related to expansion. The ethylene sales price also does not increase to cover our cost of debt or public partnership costs. All of these costs reduce our net operating profit.
The fee structure of the Ethylene Sales Agreement may limit OpCo's ability to take advantage of favorable market developments in the future.
The Ethylene Sales Agreement sets a $0.10 per pound margin for a substantial majority of OpCo's ethylene production, limiting OpCo's ability to take advantage of potential decreased ethane and other feedstock prices, potential increased ethylene prices or other favorable market developments. Under these circumstances, OpCo may not be in a position to enable its partners, including us, to benefit from favorable market developments (including any potential ethylene price increase in the future) through increased distributions. In addition, under these circumstances, OpCo may be disadvantaged relative to those of its competitors that are in a better position to take advantage of favorable market developments.
If OpCo is unable to renew or extend the Ethylene Sales Agreement beyond the initial 12-year initial term or the other agreements with Westlake upon expiration of these agreements, our ability to make distributions in the future could be materially adversely affected and the value of our units could decline.
Westlake's obligations under the Ethylene Sales Agreement, the Feedstock Supply Agreement and the related Services and Secondment Agreement continue in effect until December 31, 2026, after which such agreements will extend on an annual basis unless and until terminated by either party upon at least 12 months' prior written notice. If OpCo were unable to reach agreement with Westlake on an extension or replacement of these agreements, then our ability to make distributions on our common units could be materially adversely affected and the value of our common units could decline.
OpCo has the right to use the real property underlying Lake Charles Olefins and Calvert City Olefins pursuant to two, 50-year site lease agreements with Westlake. If OpCo is not able to renew the site lease agreements or if the site lease agreements are terminated by Westlake, OpCo may have to relocate Lake Charles Olefins and Calvert City Olefins, abandon the assets or sell the assets to Westlake.
Westlake has (1) leased to OpCo the real property underlying Lake Charles Olefins and Calvert City Olefins and (2) granted OpCo rights to access and use certain other portions of Westlake's facilities that are necessary to operate OpCo's units at such facilities. The site lease agreements each have a term of 50 years and may be renewed if agreed to by the parties. If an event of default with respect to bankruptcy of OpCo occurs, if Westlake terminates the Ethylene Sales Agreement in accordance with its provisions either for cause or due to a force majeure event, or if OpCo ceases to operate Lake Charles Olefins or Calvert City Olefins for six consecutive months (other than due to force majeure or construction following a casualty loss), Westlake may terminate the applicable site lease following notice and expiration of a cure period to remedy the default. In addition, if OpCo fails to act in good faith to expeditiously restore Lake Charles Olefins or Calvert City Olefins following a casualty loss, Westlake has the ability to terminate the applicable site lease agreement, to restore Lake Charles Olefins or Calvert City Olefins, as the case may be, and to purchase such ethylene production facilities at fair market value. If OpCo is unable to renew the site lease agreements or if Westlake terminates one or both of the site lease agreements, OpCo may have to relocate Lake Charles Olefins and Calvert City Olefins, abandon the assets or sell the assets to Westlake, the result of which may have a material adverse effect on our business, results of operations and financial condition.
12
OpCo depends upon Westlake for numerous services and for its labor force.
Pursuant to the Services and Secondment Agreement, Westlake is obligated to provide OpCo operating services, utility access services and other key site services. Westlake provides the services of certain of its employees, who act as OpCo's agents in operating and maintaining OpCo's ethylene production facilities and other assets. If this agreement is terminated or if Westlake or its affiliates fail to satisfactorily provide these services or employees, OpCo would be required to hire labor, provide these services internally or find a third-party provider of these services. Any services or labor OpCo chooses to provide internally may not be as cost effective as those that Westlake or its affiliates provide, particularly in light of OpCo's lack of experience as an independent organization. If OpCo is required to obtain these services or labor from a third party, it may be unable to do so in a timely, efficient and cost-effective manner, the services or labor it receives may be inferior to or more costly than those that Westlake is currently providing, or such services and labor may be unavailable. Moreover, given the integration of OpCo's ethylene production facilities and Westlake's Lake Charles and Calvert City facilities, it may not be practical for us or for a third party to provide site services or labor for OpCo's ethylene production facilities separately.
Additionally, certain of Westlake's employees in North America are represented by labor unions and works councils. Our operations may be adversely affected by strikes, work stoppages and other labor disputes involving those employees that operate and maintain OpCo's ethylene production facilities and other assets. For example, on November 1, 2024, bargaining unit employees of Local Lodge No. 2781 of the IAM began a strike at our Calvert City, Kentucky facility, after the IAM members did not accept Westlake's final offer for a new collective bargaining agreement. The strike ended on November 8, 2024, after the IAM accepted Westlake's offer for a new collective bargaining agreement. Any future strikes or work stoppages could be significant and have an adverse effect on our financial condition and results of operations.
OpCo's ability to receive greater cash flows from increased production may be limited by the Ethylene Sales Agreement.
OpCo's ability to increase throughput volumes through its assets is constrained by the capacity limitations of those assets, which are currently operating at close to full capacity. OpCo's ability to increase its cash flow by selling ethylene to third parties may be limited by the Ethylene Sales Agreement. OpCo's ability to sell ethylene to third parties is limited to available excess capacity, since Westlake has the right to purchase the substantial majority of production from OpCo's facilities through its minimum purchase commitment and option to purchase additional ethylene under the Ethylene Sales Agreement. The Ethylene Sales Agreement provisions may prohibit OpCo from competing effectively for third party business for this excess production given the limited volumes available for sale. For example, so long as Westlake is not in default under the Ethylene Sales Agreement, Westlake has the right to purchase 95% of OpCo's production in excess of planned capacity.
Cost reimbursements due to our general partner and Westlake for services provided to us or on our behalf reduce our earnings and therefore our cash available for distribution to our unitholders. The amount and timing of such reimbursements are determined by our general partner.
We are obligated under our partnership agreement to reimburse our general partner and its affiliates for all expenses they incur and payments they make on our behalf, including expenses we and OpCo incur under the Services and Secondment Agreement and the Omnibus Agreement. Our partnership agreement does not set a limit on the amount of expenses for which our general partner and its affiliates may be reimbursed. These expenses include all expenses incurred under the Services and Secondment Agreement and the Omnibus Agreement, including salary, bonus, incentive compensation and other amounts paid to persons who perform services for us or on our behalf and expenses allocated to our general partner by its affiliates. Our partnership agreement provides that our general partner determines the expenses that are allocable to us. The reimbursement of expenses and payment of fees, if any, to our general partner and its affiliates reduce the amount of our earnings and, thereby, our ability to distribute cash to our unitholders.
13
Business Operations
Substantially all of OpCo's sales are generated at three facilities located at two sites. Any adverse developments at any of these facilities or sites could have a material adverse effect on our results of operations and therefore our ability to distribute cash to unitholders.
OpCo's operations are subject to significant hazards and risks inherent in ethylene production operations. These hazards and risks include, but are not limited to, equipment malfunction, explosions, fires and the effects of severe weather conditions, any of which could result in production and transportation difficulties and disruptions, pollution, personal injury or wrongful death claims and other damage to our properties and the property of others. There is also risk of mechanical failure of OpCo's facilities both in the normal course of operations and following unforeseen events. Any adverse developments at any of OpCo's facilities could have a material adverse effect on our results of operations and therefore our ability to distribute cash to unitholders.
Because substantially all of OpCo's sales are generated at three facilities located at two sites, any such events at any facility or site could significantly disrupt OpCo's ethylene production and its ability to supply ethylene to its customers. For example, OpCo's Lake Charles facility was shut down for a significant period of time in the months of August, September and October 2020 in the aftermath of Hurricanes Laura and Delta. Any similar or other sustained disruption in OpCo's ability to meet its supply obligations under the Ethylene Sales Agreement could have a material adverse effect on our results of operations and therefore our ability to distribute cash to unitholders.
The amount of cash we have available for distribution to holders of our units depends primarily on our cash flow and not solely on profitability, which may prevent us from making cash distributions during periods when we record net income.
The amount of cash we have available for distribution depends primarily upon our cash flow, including cash flow from reserves and working capital or borrowings (including any under our and OpCo's credit facilities) and not solely on profitability, which will be affected by non-cash items. As a result, we may pay cash distributions during periods when we record net losses for financial accounting purposes and may be unable to pay cash distributions during periods when we record net income. We may be unable to access our and OpCo's revolving credit facilities when we do not have sufficient cash flows to pay cash distributions.
If we are unable to make acquisitions from Westlake or third parties on economically acceptable terms, our future growth would be limited, and any acquisitions we make may reduce, rather than increase, our cash generated from operations on a per unit basis.
Our strategy to grow our business and increase distributions to unitholders is dependent on our ability to make acquisitions that result in an increase in our cash distributions per unit. If we are unable to make acquisitions of additional interests in OpCo from Westlake on acceptable terms or we are unable to obtain financing for these acquisitions, our future growth and ability to increase distributions will be limited. In addition, we may be unable to make acquisitions from third parties as an alternative avenue to growth. Furthermore, even if we do consummate acquisitions that we believe will be accretive, they may in fact result in a decrease in our cash distributions per unit. Any acquisition involves potential risks, some of which are beyond our control, including, among other things:
•mistaken assumptions about revenues and costs, including synergies;
•the inability to successfully integrate the businesses we acquire;
•the inability to hire, train or retain qualified personnel to manage and operate our business and newly acquired assets;
•the assumption of unknown liabilities;
•limitations on rights to indemnity from the seller;
•mistaken assumptions about the overall costs of equity or debt;
•the diversion of management's attention from other business concerns;
•unforeseen difficulties in connection with operating in new product areas or new geographic areas; and
•customer or key employee losses at the acquired businesses.
If we consummate any future acquisitions, our capitalization and results of operations may change significantly, and unitholders will not have the opportunity to evaluate the economic, financial and other relevant information that we will consider in determining the application of our funds and other resources.
14
Many of our assets have been in service for many years and require significant expenditures to maintain them. As a result, our maintenance or repair costs may increase in the future. In addition, while we establish cash reserves in order to cover turnaround expenditures, the amounts we reserve may not be sufficient to fully cover such expenditures.
Many of the assets we use to produce ethylene are long-lived assets. As a result, some of those assets have been in service for many decades. The age and condition of these assets could result in increased maintenance or repair expenditures. In addition, while we establish certain cash reserves to cover our expected turnaround expenditures, the amounts we reserve may be insufficient to fully cover such expenditures. Any significant and unexpected increase in these expenditures could adversely affect our results of operations, financial position or cash flows, as well as our ability to pay cash distributions.
Our production facilities process volatile and hazardous materials that subject us to operating risks that could adversely affect our operating results.
Our operations are subject to the usual hazards associated with commodity chemical manufacturing and the related use, storage, transportation and disposal of feedstocks, products and wastes, including:
•pipeline leaks and ruptures;
•explosions;
•fires;
•severe weather and natural disasters;
•long-term impacts of climate change; including rising sea levels and changes in weather patterns, such as drought and flooding;
•mechanical failure;
•unscheduled downtime;
•labor difficulties;
•transportation interruptions;
•chemical spills;
•discharges or releases of toxic or hazardous substances or gases;
•storage tank leaks;
•other environmental risks; and
•terrorist attacks.
All of these hazards can cause personal injury and loss of life, catastrophic damage to or destruction of property and equipment and environmental damage, and may result in a suspension of operations and the imposition of civil or criminal penalties. We could become subject to environmental claims brought by governmental entities or third parties. A loss or shutdown of operations over an extended period at any one of our three major operating facilities would have a material adverse effect on us. Through Westlake, we maintain property, business interruption and casualty insurance that we believe is in accordance with customary industry practices, but we cannot be fully insured against all potential hazards incident to our business, including losses resulting from wars or terrorist acts, among other things. In addition, certain policies may be subject to coverage limitations, which may affect the extent of any recovery thereunder. As a result of market conditions and past claims, premiums and deductibles for certain insurance policies can increase substantially and, in some instances, certain insurance may become unavailable or available only for reduced amounts of coverage. If we were to incur a significant liability for which we were not fully insured, it could have a material adverse effect on our financial position.
15
Our operations and assets are subject to extensive environmental, health and safety laws and regulations.
We use hazardous substances and generate hazardous wastes and emissions in our manufacturing operations. Our industry is highly regulated and monitored by various environmental regulatory authorities such as the Environmental Protection Agency (the "EPA"). As such, we are subject to extensive federal, state and local laws and regulations pertaining to pollution and protection of the environment, health and safety, which govern, among other things, emissions to the air, discharges onto land or waters, the maintenance of safe conditions in the workplace, the remediation of contaminated sites, and the generation, handling, storage, transportation, treatment and disposal of waste materials. Some of these laws and regulations are subject to varying and conflicting interpretations. Many of these laws and regulations provide for substantial fines and potential criminal sanctions for violations and require the installation of costly pollution control equipment or operational changes to limit pollution emissions or reduce the likelihood or impact of hazardous substance releases, whether permitted or not. For example, our petrochemical facilities may require improvements to comply with certain changes in process safety management requirements.
In April 2016, the EPA issued an Information Collection Request ("ICR") for ethylene production facilities to inform the agency's mandatory Risk and Technology Review of the existing ethylene maximum available technology ("MACT") rule, which regulates the emissions of organic Hazardous Air Pollutants ("HAP") including benzene, toluene and xylene among others. The EPA evaluated companies' responses and testing data from the ICR and published a final rule amending the ethylene MACT rule in July 2020. Among other things, the final rule strengthens heat exchange system and storage vessel control requirements, adds monitoring and operational requirements for flares, and removes exemptions for periods of startup, shutdown, and malfunctions. On April 27, 2023, the EPA proposed amendments to the National Emission Standards for Hazardous Air Pollutants ("NESHAPs") for ethylene production following the receipt of several petitions for reconsideration for the provisions addressing work practice standards for pressure relief devices, emergency flaring, and degassing of floating roof storage vessels. On April 4, 2024, the EPA finalized the proposed amendments, removing the force majeure exemption for pressure relief devices and emergency flaring, clarifying degassing requirements for floating roof storage vessels, and addressing other corrections and clarifications.
In April 2023, the EPA proposed amendments to new source performance standards for the synthetic organic chemical manufacturing industry and amendments to the national emissions standards for hazardous air pollutants for the synthetic organic chemical manufacturing industry and group I & II polymers and resins industry. The proposed amendments were finalized on May 16, 2024 and became effective July 15, 2024. These amendments, among other things, impose tougher emissions limits, additional leak detection and repair obligations, certain performance standards for the operation of flares at applicable facilities, and new fenceline air monitoring for several chemicals. The amendments may require us to incur further capital expenditures and increase operating costs.
16
Our operations also produce greenhouse gas ("GHG") emissions, which have been the subject of increased scrutiny and regulation. In December 2015, the United States joined the international community at the 21st Conference of the Parties of the United Nations Framework Convention on Climate Change in Paris, France. The resulting Paris Agreement calls for the parties to undertake "ambitious efforts" to limit the average global temperature and to conserve and enhance sinks and reservoirs of greenhouse gases. The United States signed the Paris Agreement in April 2016, and the Paris Agreement went into effect in November 2016. In November 2019, the United States submitted formal notification to the United Nations that it intended to withdraw from the Paris Agreement. The withdrawal took effect in November 2020. However, President Biden signed an executive order on January 20, 2021 for reentry of the United States into the Paris Agreement and on February 19, 2021, President Biden formally rejoined the Paris Agreement. As part of rejoining the Paris Agreement, President Biden announced that the United States would commit to a 50 to 52 percent reduction from 2005 levels of GHG emissions by 2030 and set the goal of reaching net-zero GHG emissions by 2050. To measure progress towards this target, the Paris Agreement requires the parties to complete a global stocktake, assessing members' collective efforts and achievements in reducing GHG emissions and adapting to the impacts of climate change, every five years. On December 13, 2023, the 28th annual United Nations Climate Change Conference ("COP 28"), which was held in Dubai, issued its first global stocktake, which calls on parties, including the United States, to contribute to the transitioning away from fossil fuels, reduce methane emissions, and increase renewable energy capacity, among other things, to achieve net zero emissions by 2050. In January 2025, the United States submitted formal notification to the United Nations that it intends to withdraw from the Paris Agreement. Pursuant to the terms of the Paris Agreement, the withdrawal will take effect in January 2026. Legislation to regulate GHG emissions has periodically been introduced in the United States Congress, and such legislation may be proposed or adopted in the future. There has been a wide-ranging policy debate regarding the impact of these gases and possible means for their regulation. Some of the proposals would require industries to meet stringent new standards that would require substantial reductions in carbon emissions. The adoption and implementation of any international, federal or state legislation or regulations that restrict emissions of GHGs could result in increased compliance costs or additional operating restrictions. The EPA has adopted rules requiring the reporting of GHG emissions from specified large GHG emission sources on an annual basis including our facilities in Lake Charles and Calvert City. Various jurisdictions have considered or adopted laws and regulations on GHG emissions, with the general aim of reducing such emissions. The EPA currently requires certain industrial facilities to report their GHG emissions and to obtain permits with stringent control requirements before constructing or modifying new facilities with significant criteria pollutant and GHG emissions. As our chemical processing results in GHG emissions, these and other GHG laws and regulations could affect our costs of doing business.
Various jurisdictions have considered or adopted laws and regulations on GHG emissions, with the general aim of reducing such emissions. The EPA currently requires certain industrial facilities to report their GHG emissions, and to obtain permits with stringent control requirements before constructing or modifying new facilities with significant GHG emissions.
On March 6, 2024, the U.S. Securities and Exchange Commission ("SEC") adopted a new set of rules that require a wide range of climate-related disclosures, including material climate-related risks, information on any climate-related targets or goals that are material to the registrant's business, results of operations, or financial condition, Scope 1 and Scope 2 GHG emissions on a phased-in basis by certain larger registrants when those emissions are material and the filing of an attestation report covering the same, and disclosure of the financial statement effects of severe weather events and other natural conditions including costs and losses. Multiple lawsuits have been filed challenging the SEC's new climate rules, and on April 4, 2024, the SEC issued an order staying the final rules until judicial review is complete. In September 2023, California passed climate-related disclosure mandates that are broader than the SEC's rules. As our chemical processing results in GHG emissions, these and other environmental disclosure laws and regulations could affect our costs of doing business.
We also may face liability for alleged personal injury or property damage due to exposure to chemicals or other hazardous substances at our facilities or to chemicals that we otherwise manufacture, handle or own. Although these types of claims have not historically had a material impact on our operations, a significant increase in the success of these types of claims could have a material adverse effect on our business, financial condition, operating results or cash flow.
Environmental laws may have a significant effect on the nature and scope of, and responsibility for, cleanup of contamination at our current and former operating facilities, the costs of transportation and storage of raw materials and finished products, the costs of reducing emissions and the costs of the storage and disposal of wastewater. The U.S. Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") and similar state laws impose joint and several liability for the costs of remedial investigations and actions on the entities that generated waste, arranged for disposal of the waste, transported to or selected the disposal sites, and the past and present owners and operators of disposal sites. All such potentially responsible parties (or any one of them, including us) may be required to bear all of such costs regardless of fault, legality of the original disposal or ownership of the disposal site. In addition, CERCLA and similar state laws could impose liability for damages to natural resources caused by contamination.
17
Although we seek to take preventive action, our operations are inherently subject to accidental spills, discharges or other releases of hazardous substances that may make us liable to governmental entities or private parties. This may involve contamination associated with our current and former facilities, facilities to which we sent wastes or by-products for treatment or disposal and other contamination. Accidental discharges may occur in the future, future action may be taken in connection with past discharges, governmental agencies may assess damages or penalties against us in connection with any past or future contamination, or third parties may assert claims against us for damages allegedly arising out of any past or future contamination. In addition, we may be liable for existing contamination related to certain of our facilities for which, in some cases, we believe third parties are liable in the event such third parties fail to perform their obligations.
Our operations and assets are subject to climate-related risks and uncertainties.
We are subject to increasing climate-related risks and uncertainties, many of which are outside of our control. Climate change may result in more frequent severe weather events, potential changes in precipitation patterns, flooding, sea level rise and variability in weather patterns, which can disrupt our operations as well as those of our customers, partners and suppliers. Climate change may result in heightened hurricane activity in the Gulf of Mexico and other weather and natural disaster hazards that pose a risk to OpCo's facilities, particularly those in Louisiana. The transition to lower greenhouse gas emissions technology, the effects of carbon pricing, changes in public sentiment, regulations, taxes, public mandates or requirements, increases in climate-related lawsuits, insurance premiums and implementation of more robust disaster recovery and business continuity plans may increase costs to maintain or resume our operations, which could in turn negatively impact our business and results of operations.
We are subject to operational and financial risks and liabilities associated with the implementation of and efforts to achieve carbon emission reduction goals.
Westlake has publicly announced a target 20% reduction in its Scope 1 and Scope 2 CO2 equivalent emissions intensity per ton of production by 2030 from a 2016 baseline. Developing and implementing plans for compliance with voluntary climate commitments can lead to additional capital, personnel, operations and maintenance expenditures and could significantly affect the economic position of existing facilities and proposed projects. Westlake's failure or perceived failure to pursue or fulfill its sustainability-focused goals, targets and objectives within the timelines announced, or at all, could adversely affect our business or reputation, as well as expose us to potential government enforcement actions and private litigation. We cannot predict the ultimate impact of achieving Westlake's emissions reduction goal, or the various implementation aspects, on our financial condition and results of operations.
Failure to adequately protect critical data and technology systems could materially affect our operations.
We are increasingly dependent on digital technologies and services to conduct our business. We use these technologies for internal and operational purposes, including data storage, processing, and transmission, as well as in our interactions with our business associates, such as customers and suppliers.
Information technology system failures, network disruptions and breaches of data security due to internal or external factors including cyber-attacks could have material adverse impacts on our business or cause disruptions to our operations. Such disruptions could include, but are not limited to, delaying or cancelling customer orders, impeding the manufacture or shipment of products or causing standard business processes to become ineffective, or the unintentional or malicious disclosure of proprietary, confidential or other sensitive information. Cyber-attacks could include, but are not limited to, ransomware attacks, malicious software, attempts to gain unauthorized access to our systems or data or other electronic security breaches that could lead to disruptions in critical systems, unauthorized release, corruption or loss of data including protected information such as personal information of our employees, interruptions in communication, loss of our intellectual property or theft of our sensitive or proprietary technology, loss or damage to our data delivery systems, or other cybersecurity and infrastructure systems, including our property and equipment, diversion of management or work force attention, or increased costs required to prevent, respond to or mitigate the incident. In addition, cybersecurity risk is exacerbated with the advancement of technologies like artificial intelligence, which malicious third parties are using to create new, sophisticated and more frequent attacks.
Westlake's and our employees, systems, networks, products, facilities and services remain potentially vulnerable to sophisticated cyber-attacks, including the additional cybersecurity risks posed by the increased use of remote networking technologies and services, and, as such, there can be no assurance that a system failure, network disruption or data security breach will not have a material adverse effect on our operations, business, financial condition, operating results or cash flow. In addition, laws and regulations governing cybersecurity, data privacy, and the unauthorized disclosure of confidential or protected information pose increasingly complex compliance challenges, and failure to comply with these laws could result in penalties and legal liability.
18
Our variable-rate debt exposes us to increases in interest rates, which could have a material impact on our financial position, results of operation and cash flows, and could reduce the price at which our common units trade.
We are exposed to interest rate risk with respect to our outstanding debt, all of which is variable-rate debt. At December 31, 2024, we had $399.7 million in principal amount of variable-rate debt outstanding, including $22.6 million outstanding under the OpCo Revolver and $377.1 million outstanding under the MLP Revolver. Each of the OpCo Revolver and the MLP Revolver have interest rates in-part based on SOFR at the time of any borrowing.
The Board of Governors of the Federal Reserve System increased benchmark interest rates four times in 2023 and lowered benchmark interest rates three times in 2024. However, rates remain above the ten-year average and may rise in future periods. Should interest rates increase significantly, the amount of cash required to service our debt would increase. As a result, significant increases in interest rates could have a material impact on our financial position, results of operations and cash flows.
An increase in interest rates may also cause a corresponding decline in demand for equity securities in general, and in particular, for yield-based equity securities such as our common units. A reduction in demand for our common units may cause their trading price to decline.
A terrorist attack or armed conflict could harm our business.
Terrorist activities, anti-terrorist efforts and other armed conflicts involving the United States or other jurisdictions could adversely affect the United States and global economies and could prevent us from meeting financial and other obligations. We could experience loss of business, delays or defaults in payments from customers or disruptions of fuel supplies and markets if North American and global utilities are direct targets or indirect casualties of an act of terror or war. Terrorist activities and the threat of potential terrorist activities and any resulting economic downturn could adversely affect our results of operations, impair our ability to raise capital or otherwise adversely impact our ability to realize certain business strategies.
The impact and effects of public health crises, pandemics and epidemics could materially adversely affect OpCo's business, financial condition and results of operations.
Public health crises, pandemics and epidemics, such as the COVID-19 pandemic, could materially adversely affect OpCo's business, financial condition and results of operations. Such events have resulted in and may again result in authorities implementing numerous measures to try to contain the disease, such as travel bans and restrictions, quarantines, shelter-in-place orders and shutdowns, among others. Such events have had and could again have widespread adverse impacts on the global economy, many of OpCo's facilities and its employees, customers and suppliers. These and similar events have caused and may again cause supply chain constraints and disruptions and workforce availability issues as well.
Risks Relating to Our Partnership Structure
Our General Partner
Westlake owns and controls our general partner, which has sole responsibility for conducting our business and managing our operations. Our general partner and its affiliates, including Westlake, may have conflicts of interest with us and have limited duties, and they may favor their own interests to our detriment and that of our unitholders.
Westlake owns and controls our general partner and appoints all of the directors of our general partner. Although our general partner has a duty to manage us in a manner that it believes is not adverse to our interests, the executive officers and directors of our general partner have a fiduciary duty to manage our general partner in a manner beneficial to Westlake. Therefore, conflicts of interest may arise between Westlake or any of its affiliates, including our general partner, on the one hand, and us or any of our unitholders, on the other hand. In resolving these conflicts of interest, our general partner may favor its own interests and the interests of its affiliates over the interests of our common unitholders. These conflicts include the following situations, among others:
•our general partner is allowed to take into account the interests of parties other than us, such as Westlake, in exercising certain rights under our partnership agreement;
•neither our partnership agreement nor any other agreement requires Westlake to pursue a business strategy that favors us;
•our partnership agreement replaces the fiduciary duties that would otherwise be owed by our general partner with contractual standards governing its duties, limits our general partner's liabilities and restricts the remedies available to our unitholders for actions that, without such limitations, might constitute breaches of fiduciary duty;
19
•except in limited circumstances, our general partner has the power and authority to conduct our business without unitholder approval;
•our general partner determines the amount and timing of asset purchases and sales, borrowings, issuances of additional partnership securities and the level of reserves, each of which can affect the amount of cash that is distributed to our unitholders;
•our general partner determines the amount and timing of any cash expenditure and whether an expenditure is classified as a maintenance capital expenditure, which reduces operating surplus, or an expansion capital expenditure, which does not reduce operating surplus. This determination can affect the amount of cash from operating surplus that is distributed to our unitholders;
•our general partner may cause us to borrow funds in order to permit the payment of cash distributions, even if the purpose or effect of the borrowing is to make incentive distributions or may cause us not to borrow funds to pay cash distributions when we do not otherwise have the funds to pay such cash distributions;
•our partnership agreement permits us to distribute up to $28.0 million as operating surplus, even if it is generated from asset sales, non-working capital borrowings or other sources that would otherwise constitute capital surplus. This cash may be used to fund distributions on the incentive distribution rights;
•our general partner determines which costs incurred by it and its affiliates are reimbursable by us;
•our partnership agreement does not restrict our general partner from causing us to pay it or its affiliates for any services rendered to us or entering into additional contractual arrangements with its affiliates on our behalf;
•our general partner intends to limit its liability regarding our contractual and other obligations;
•our general partner may exercise its right to call and purchase common units if it and its affiliates own more than 80% of the common units;
•our general partner controls the enforcement of obligations that it and its affiliates owe to us;
•our general partner decides whether to retain separate counsel, accountants or others to perform services for us; and
•our general partner may elect to cause us to issue common units to it in connection with a resetting of the target distribution levels related to Westlake's incentive distribution rights without the approval of the conflicts committee of the board of directors or the unitholders. This election may result in lower distributions to the common unitholders in certain situations.
In addition, we may compete directly with Westlake and entities in which it has an interest for acquisition opportunities and potentially will compete with these entities for new business or extensions of the existing services provided by us. See "—Risks Relating to Our Partnership Structure—Our General Partner—Westlake and other affiliates of our general partner may compete with us" below.
Our general partner has limited its liability regarding our obligations.
Our general partner has limited its liability under contractual arrangements between us and third parties so that the counterparties to such arrangements have recourse only against our assets, and not against our general partner or its assets. Our general partner may therefore cause us to incur indebtedness or other obligations that are nonrecourse to our general partner. Our partnership agreement provides that any action taken by our general partner to limit its liability is not a breach of our general partner's duties, even if we could have obtained more favorable terms without the limitation on liability.
Our partnership agreement replaces our general partner's fiduciary duties to holders of our units.
Our partnership agreement contains provisions that eliminate and replace the fiduciary standards to which our general partner would otherwise be held by state fiduciary duty law. For example, our partnership agreement permits our general partner to make a number of decisions in its individual capacity, as opposed to in its capacity as our general partner, or otherwise free of fiduciary duties to us and our unitholders. This entitles our general partner to consider only the interests and factors that it desires and relieves it of any duty or obligation to give any consideration to any interest of, or factors affecting, us, our affiliates or our limited partners. Examples of decisions that our general partner may make in its individual capacity include:
•how to allocate business opportunities among us and its affiliates;
•whether to exercise its call right;
•how to exercise its voting rights with respect to the units it owns;
20
•whether to exercise its registration rights;
•whether to elect to reset target distribution levels; and
•whether or not to consent to any merger or consolidation of the partnership or amendment to the partnership agreement.
By purchasing a common unit, a unitholder is treated as having consented to the provisions in the partnership agreement, including the provisions discussed above.
Our partnership agreement restricts the remedies available to holders of our units for actions taken by our general partner that might otherwise constitute breaches of fiduciary duty.
Our partnership agreement contains provisions that restrict the remedies available to unitholders for actions taken by our general partner that might otherwise constitute breaches of fiduciary duty under state fiduciary duty law. For example, our partnership agreement provides that:
•whenever our general partner makes a determination or takes, or declines to take, any other action in its capacity as our general partner, our general partner is generally required to make such determination, or take or decline to take such other action, in good faith, and will not be subject to any higher standard imposed by our partnership agreement, Delaware law, or any other law, rule or regulation, or at equity;
•our general partner and its officers and directors will not be liable for monetary damages or otherwise to us or our limited partners resulting from any act or omission unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that such losses or liabilities were the result of conduct in which our general partner or its officers or directors engaged in bad faith, meaning that they believed that the decision was adverse to the interest of the partnership or, with respect to any criminal conduct, with knowledge that such conduct was unlawful; and
•our general partner will not be in breach of its obligations under the partnership agreement or its duties to us or our limited partners if a transaction with an affiliate or the resolution of a conflict of interest is:
(1) approved by the conflicts committee of the board of directors, although our general partner is not obligated to seek such approval; or
(2) approved by the vote of a majority of the outstanding common units, excluding any common units owned by our general partner and its affiliates.
In connection with a situation involving a transaction with an affiliate or a conflict of interest, other than one where our general partner is permitted to act in its sole discretion, any determination by our general partner must be made in good faith. If an affiliate transaction or the resolution of a conflict of interest is not approved by our common unitholders or the conflicts committee, then it will be presumed that, in making its decision, taking any action or failing to act, the board of directors acted in good faith, and in any proceeding brought by or on behalf of any limited partner or the partnership, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption.
Our partnership agreement provides that the conflicts committee of the board of directors may be comprised of one or more independent directors. If the board of directors establishes a conflicts committee with only one independent director, your interests may not be as well served as if the conflicts committee was comprised of at least two independent directors. A single-member conflicts committee would not have the benefit of discussion with, and input from, other independent directors.
Westlake and other affiliates of our general partner may compete with us.
Affiliates of our general partner, including Westlake, are not prohibited from engaging in other businesses or activities, including those that might be in direct competition with us. In addition, Westlake may compete with us for investment opportunities and may own an interest in entities that compete with us.
Pursuant to the terms of our partnership agreement, the doctrine of corporate opportunity, or any analogous doctrine, does not apply to our general partner or any of its affiliates, including its executive officers and directors and Westlake. Any such person or entity that becomes aware of a potential transaction, agreement, arrangement or other matter that may be an opportunity for us will not have any duty to communicate or offer such opportunity to us. Any such person or entity will not be liable to us or to any limited partner for breach of any fiduciary duty or other duty by reason of the fact that such person or entity pursues or acquires such opportunity for itself, directs such opportunity to another person or entity or does not communicate such opportunity or information to us. This may create actual and potential conflicts of interest between us and affiliates of our general partner and result in less than favorable treatment of us and our unitholders.
21
Holders of our common units have limited voting rights and are not entitled to elect our general partner or its directors, which could reduce the price at which our common units trade.
Compared to the holders of common stock in a corporation, unitholders have limited voting rights and, therefore, limited ability to influence management's decisions regarding our business. Unitholders will have no right on an annual or ongoing basis to elect our general partner or its board of directors. The board of directors, including the independent directors, is chosen entirely by Westlake, as a result of it owning our general partner, and not by our unitholders. Unlike publicly-traded corporations, we do not conduct annual meetings of our unitholders to elect directors or conduct other matters routinely conducted at annual meetings of stockholders of corporations. As a result of these limitations, the price at which the common units trade could be diminished because of the absence or reduction of a takeover premium in the trading price.
Even if holders of our common units are dissatisfied, they cannot currently remove our general partner without its consent.
If our unitholders are dissatisfied with the performance of our general partner, they currently cannot remove our general partner. Unitholders currently are unable to remove our general partner without its consent because our general partner and its affiliates own sufficient units to be able to prevent its removal. The vote, including Westlake, of the holders of at least 66 2/3% of all outstanding common and subordinated units voting together as a single class is required to remove our general partner. As of February 26, 2025, Westlake owned an aggregate of 40.1% of our common units. This condition provides Westlake, at its current ownership levels, the ability to prevent the removal of our general partner.
Control of our general partner may be transferred to a third party without unitholder consent.
Our general partner may transfer its general partner interest to a third party without the consent of our unitholders. Furthermore, our partnership agreement permits Westlake to transfer ownership of our general partner to a third party, also without the consent of our unitholders. The new owner of our general partner would then be in a position to replace the board of directors and executive officers of our general partner with its own designees and thereby exert significant control over the decisions taken by the board of directors and executive officers of our general partner. This effectively permits a "change of control" without the vote or consent of the unitholders.
22
Our general partner has a call right that may require unitholders to sell their common units at an undesirable time or price.
If at any time our general partner and its affiliates own more than 80% of the common units, our general partner will have the right, which it may assign to any of its affiliates or to us, but not the obligation, to acquire all, but not less than all, of the common units held by unaffiliated persons at a price equal to the greater of (1) the average of the daily closing price of the common units over the 20 trading days preceding the date three days before notice of exercise of the call right is first mailed and (2) the highest per-unit price paid by our general partner or any of its affiliates for common units during the 90-day period preceding the date such notice is first mailed. As a result, unitholders may be required to sell their common units at an undesirable time or price and may not receive any return or a negative return on their investment. Unitholders may also incur a tax liability upon a sale of their units. Our general partner is not obligated to obtain a fairness opinion regarding the value of the common units to be repurchased by it upon exercise of the limited call right. There is no restriction in our partnership agreement that prevents our general partner from causing us to issue additional common units and then exercising its call right. If our general partner exercised its limited call right, the effect would be to take us private and, if the units were subsequently deregistered, we would no longer be subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act.
Cash Distributions to Unitholders
The board of directors may modify or revoke our cash distribution policy at any time at its discretion. Our partnership agreement does not require us to pay any distributions at all.
The board of directors of our general partner adopted a cash distribution policy pursuant to which we intend to distribute quarterly at least $0.2750 per unit on all of our units to the extent we have sufficient cash after the establishment of cash reserves and the payment of our expenses, including payments to our general partner and its affiliates. However, the board may change such policy at any time at its discretion and could elect not to pay distributions for one or more quarters.
In addition, our partnership agreement does not require us to pay any distributions at all. Accordingly, investors are cautioned not to place undue reliance on the permanence of such a policy in making an investment decision. Any modification or revocation of our cash distribution policy could substantially reduce or eliminate the amount we distribute to our unitholders. The amount of distributions we make, if any, and the decision to make any distribution at all will be determined by the board of directors, whose interests may differ from those of our common unitholders. Our general partner has limited duties to our unitholders, which may permit it to favor its own interests or the interests of Westlake to the detriment of our common unitholders.
We expect to distribute a significant portion of our available cash to our partners, which could limit our ability to grow and make acquisitions.
We plan to distribute most of our available cash, which may cause our growth to proceed at a slower pace than that of businesses that reinvest their cash to expand ongoing operations. To the extent we issue additional units in connection with any acquisitions or expansion capital expenditures, the payment of distributions on those additional units may increase the risk that we will be unable to maintain or increase our per unit distribution level. There are no limitations in our partnership agreement on our ability to issue additional units, including units ranking senior to the common units. The incurrence of additional commercial borrowings or other debt to finance our growth strategy would result in increased interest expense, which, in turn, may impact the cash that we have available to distribute to our unitholders.
23
The holder or holders of our incentive distribution rights may elect to cause us to issue common units to it in connection with a resetting of the target distribution levels related to the incentive distribution rights, without the approval of the conflicts committee of our board of directors or the holders of our common units. This could result in lower distributions to holders of our common units.
The holder or holders of a majority of our incentive distribution rights (currently Westlake) have the right, at any time when there are no subordinated units outstanding and we have made cash distributions in excess of the then-applicable third target distribution for each of the prior four consecutive fiscal quarters, to reset the initial target distribution levels at higher levels based on our cash distribution levels at the time of the exercise of the reset election. Following a reset election by such holder or holders, the minimum quarterly distribution will be calculated equal to an amount equal to the prior cash distribution per common unit for the fiscal quarter immediately preceding the reset election (such amount is referred to as the "reset minimum quarterly distribution") and the target distribution levels will be reset to correspondingly higher levels based on percentage increases above the reset minimum quarterly distribution. If such holder or holders elects to reset the target distribution levels, they will be entitled to receive common units as consideration for such election. The number of common units to be issued to such holder or holders will equal the number of common units that would have entitled the holder to an aggregate quarterly cash distribution for the quarter prior to the reset election equal to the distribution on the incentive distribution rights for the quarter prior to the reset election.
Westlake, as the current holder of our incentive distribution rights, could exercise this reset right in order to facilitate acquisitions or internal growth projects that would not be sufficiently accretive to cash distributions per unit without such conversion. However, Westlake may transfer the incentive distribution rights at any time. It is possible that Westlake or a transferee could exercise this reset election at a time when we are experiencing declines in our aggregate cash distributions or at a time when the holders of the incentive distribution rights expect that we will experience declines in our aggregate cash distributions in the foreseeable future. In such situations, a holder of the incentive distribution rights may be experiencing, or may expect to experience, declines in the cash distributions it receives related to the incentive distribution rights and may therefore desire to be issued our common units rather than retain the right to receive incentive distributions based on the initial target distribution levels. As a result, a reset election may cause our common unitholders to experience reduction in the amount of cash distributions that they would have otherwise received had we not issued new common units to the holders of the incentive distribution rights in connection with resetting the target distribution levels.
The incentive distribution rights may be transferred to a third party without unitholder consent.
Westlake may transfer the incentive distribution rights to a third party at any time without the consent of our unitholders. If Westlake transfers the incentive distribution rights to a third party, it would not have the same incentive to grow our partnership and increase quarterly distributions to unitholders over time. For example, a transfer of incentive distribution rights by Westlake could reduce the likelihood of it accepting offers made by us relating to assets owned by Westlake, as it would have less of an economic incentive to grow our business, which in turn would impact our ability to grow our asset base.
Ownership of Our Common Units
We may issue additional units without unitholder approval, which would dilute existing unitholder ownership interests.
Our partnership agreement does not limit the number of additional limited partner interests we may issue at any time without the approval of our unitholders. We are party to an Equity Distribution Agreement pursuant to which we may offer and sell common units from time to time to or through the investment banks, as our sales agents or as principals, having an aggregate offering amount of up to $50.0 million. The issuance of additional common units or other equity interests of equal or senior rank will have the following effects:
•our existing unitholders' proportionate ownership interest in us will decrease;
•the amount of earnings per each unit may decrease;
•the ratio of taxable income to distributions may increase;
•the relative voting strength of each previously outstanding unit may be diminished; and
•the market price of the common units may decline.
24
The market price of our common units could be adversely affected by sales of substantial amounts of our common units in the public or private markets, including sales by Westlake or other large holders.
Westlake has registration rights with respect to the common units it holds. Sales by Westlake or other large holders of a substantial number of our common units in the public markets, or the perception that such sales might occur, could have a material adverse effect on the price of our common units or could impair our ability to obtain capital through an offering of equity securities.
Our partnership agreement restricts the voting rights of unitholders owning 20% or more of our common units.
Our partnership agreement restricts unitholders' voting rights by providing that any units held by a person or group that owns 20% or more of any class of units then outstanding, other than our general partner and its affiliates, their transferees and persons who acquired such units with the prior approval of the board of directors, cannot vote on any matter.
Unitholders may have liability to repay distributions.
Under certain circumstances, unitholders may have to repay amounts wrongfully returned or distributed to them. Under Delaware law, we may not make a distribution to our unitholders if the distribution would cause our liabilities to exceed the fair value of our assets. Delaware law provides that for a period of three years from the date of the impermissible distribution, limited partners who received the distribution and who knew at the time of the distribution that it violated Delaware law will be liable to the limited partnership for the distribution amount. Liabilities to partners on account of their partnership interests and liabilities that are non-recourse to the partnership are not counted for purposes of determining whether a distribution is permitted.
Public and investor sentiment towards climate change and other sustainability matters could adversely affect our cost of capital and the price of our common units.
There have been intensifying efforts within the investment community (including investment advisors, investment fund managers, sovereign wealth funds, public pension funds, universities and individual investors) to promote the divestment of, or limit investment in, the equity of companies in the petrochemical industry. There has also been pressure on lenders and other financial services companies to limit or curtail financing of companies in the industry. Because we operate within the petrochemical industry, if these efforts continue or expand, our stock price and our ability to raise capital may be negatively impacted.
Members of the investment community are increasing their focus on sustainability practices and disclosures by public companies, including practices and disclosures related to climate change and sustainability, D&I initiatives and heightened governance standards. On March 6, 2024, the SEC adopted a new set of rules that require a wide range of climate-related disclosures, including material climate-related risks. Multiple lawsuits have been filed challenging the SEC's new climate rules, and on April 4, 2024, the SEC issued an order staying the final rules until judicial review is complete. In September 2023, California passed climate-related disclosure mandates that are broader than the SEC's rules. As a result, we may continue to face increasing pressure regarding our sustainability disclosures and practices. Additionally, members of the investment community may screen companies such as ours for sustainability disclosures and performance before investing in our common units. Over the past few years, there has also been an acceleration in investor demand for sustainability investing opportunities, and many large institutional investors have committed to increasing the percentage of their portfolios that are allocated towards sustainability investments. With respect to any of these investors, our sustainability disclosures and efforts may not satisfy the investor requirements or their requirements may not be made known to us. If we or our securities are unable to meet the sustainability standards or investment criteria set by these investors and funds, we may lose investors or investors may allocate a portion of their capital away from us, our cost of capital may increase, and our common unit price may be negatively impacted.
Tax Risks
Our tax treatment depends on our status as a partnership for U.S. federal income tax purposes, and not being subject to a material amount of entity-level taxation. If the Internal Revenue Service ("IRS"), were to treat us as a corporation for U.S. federal income tax purposes, or we become subject to entity-level taxation for state tax purposes, our cash available for distribution to our unitholders would be substantially reduced.
The anticipated after-tax economic benefit of an investment in our common units depends largely on our being treated as a partnership for U.S. federal income tax purposes. Despite the fact that we are organized as a limited partnership under Delaware law, we would be treated as a corporation for U.S. federal income tax purposes unless we satisfy a "qualifying income" requirement. Based upon our current operations and current Treasury Regulations, we believe we satisfy the qualifying income requirement.
25
Prior to our initial public offering, we requested and obtained a favorable private letter ruling from the IRS to the effect that, based on facts presented in the private letter ruling request, our income from the production, transportation, storage and marketing of ethylene and its co-products constitutes "qualifying income" within the meaning of Section 7704 of the Internal Revenue Code of 1986, as amended (the "Code"). However, no ruling has been or will be requested regarding our treatment as a partnership for U.S. federal income tax purposes. Failing to meet the qualifying income requirement or a change in current law could cause us to be treated as a corporation for U.S. federal income tax purposes or otherwise subject us to taxation as an entity.
If we were treated as a corporation for U.S. federal income tax purposes, we would pay U.S. federal income tax on our taxable income at the corporate tax rate. Distributions to our unitholders would generally be taxed again as corporate distributions, and no income, gains, losses or deductions would flow through to our unitholders. Because a tax would be imposed upon us as a corporation, our cash available for distribution to our unitholders would be substantially reduced. Therefore, treatment of us as a corporation would result in a material reduction in the anticipated cash flow and after-tax return to our unitholders, likely causing a substantial reduction in the value of our common units.
Our partnership agreement provides that if a law is enacted or existing law is modified or interpreted in a manner that subjects us to taxation as a corporation or otherwise subjects us to entity-level taxation for U.S. federal, state, local or foreign income tax purposes, the minimum quarterly distribution amount and the target distribution amounts may be adjusted to reflect the impact of that law or interpretation on us. At the state level, several states have been evaluating ways to subject partnerships to entity-level taxation through the imposition of state income, franchise or other forms of taxation. We currently own assets and conduct business in several states, most of which impose entity-level franchise or gross receipt taxes on partnerships. In the future, we may expand our operations. Imposition of similar entity-level taxes on us in other jurisdictions that we may expand to, could substantially reduce our cash available for distribution to our unitholders.
The tax treatment of publicly-traded partnerships or an investment in our units could be subject to potential legislative, judicial or administrative changes or differing interpretations, possibly applied on a retroactive basis.
The present U.S. federal income tax treatment of publicly-traded partnerships, including us, or an investment in our common units, may be modified by administrative, legislative or judicial changes or differing interpretations at any time. Members of Congress and the President have frequently proposed and considered substantive changes to the existing U.S. federal income tax laws that would affect publicly-traded partnerships, including proposals that would eliminate our ability to qualify for partnership tax treatment. Recent proposals have provided for the expansion of the qualifying income exception for publicly traded partnerships in certain circumstances and other proposals have provided for the total elimination of the qualifying income exception upon which we rely for our partnership tax treatment. Further, while unitholders of publicly traded partnerships are, subject to certain limitations, entitled to a deduction equal to 20% of their allocable share of a publicly traded partnership's "qualified business income," this deduction is scheduled to expire with respect to taxable years beginning after December 31, 2025.
In addition, the Treasury Department has issued, and in the future may issue, regulations interpreting those laws that affect publicly-traded partnerships. On January 24, 2017, final regulations regarding which activities give rise to qualifying income within the meaning of Section 7704 of the Code (the "Final Regulations") were published in the Federal Register. The Final Regulations, consistent with our private letter ruling, treat our income from the production, transportation, storage and marketing of ethylene and its co-products as "qualifying income." There can be no assurance that there will not be further changes to U.S. federal income tax laws or the Treasury Department's interpretation of the qualifying income rules in a manner that could impact our ability to qualify as a partnership in the future.
Any modification to the U.S. federal income tax laws and interpretations thereof may or may not be retroactively applied and could make it more difficult or impossible for us to meet the exception for certain publicly-traded partnerships to be treated as partnerships for U.S. federal income tax purposes. We are unable to predict whether any changes or other proposals will ultimately be enacted. Any future legislative changes could negatively impact the value of an investment in our common units. You are urged to consult with your own tax advisor with respect to the status of regulatory or administrative developments and proposals and their potential effect on your investment in our common units.
26
If the IRS were to contest the U.S. federal income tax positions we take, it may adversely impact the market for our common units, and the costs of any such contest would reduce our cash available for distribution to our unitholders.
The IRS may adopt positions that differ from the positions we take. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions we take. A court may not agree with some or all of the positions we take. Any contest with the IRS may materially and adversely impact the market for our common units and the price at which they trade. Moreover, the costs of any contest between us and the IRS will result in a reduction in our cash available for distribution to our unitholders and thus will be borne indirectly by our unitholders.
If the IRS makes audit adjustments to our income tax returns, it (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustments directly from us, in which case our cash available for distribution to our unitholders might be substantially reduced and our current and former unitholders may be required to indemnify us for any taxes (including any applicable penalties and interest) resulting from such audit adjustments that were paid on such unitholders behalf.
If the IRS makes audit adjustments to our income tax returns, it (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustments directly from us. To the extent possible under these rules, our general partner may elect to either pay the taxes (including any applicable penalties and interest) directly to the IRS or, if we are eligible, issue a revised information statement to each unitholder and former unitholder with respect to an audited and adjusted return. Although our general partner may elect to have our unitholders and former unitholders take such audit adjustment into account and pay any resulting taxes (including applicable penalties or interest) in accordance with their interests in us during the tax year under audit, there can be no assurance that such election will be practical, permissible or effective in all circumstances. As a result, our current unitholders may bear some or all of the tax liability resulting from such audit adjustment, even if such unitholders did not own units in us during the tax year under audit. If, as a result of any such audit adjustment, we are required to make payments of taxes, penalties and interest, our cash available for distribution to our unitholders might be substantially reduced and our current and former unitholders may be required to indemnify us for any taxes (including any applicable penalties and interest) resulting from such audit adjustments that were paid on such unitholders behalf. Additionally, we may be required to allocate an adjustment disproportionately among our unitholders, causing our publicly traded units to have different capital accounts, unless the IRS issues further guidance.
In the event the IRS makes an audit adjustment to our income tax returns and we do not or cannot shift the liability to our unitholders in accordance with their interests in us during the year under audit, we will generally have the ability to request that the IRS reduce the determined underpayment by reducing the suspended passive loss carryovers of our unitholders (without any compensation from us to such unitholders), to the extent such underpayment is attributable to a net decrease in passive activity losses allocable to certain partners. Such reduction, if approved by the IRS, will be binding on any affected unitholders.
Even if unitholders do not receive any cash distributions from us, unitholders will be required to pay taxes on their share of our taxable income.
Unitholders are required to pay U.S. federal income taxes and, in some cases, state and local income taxes, on their share of our taxable income, whether or not they receive cash distributions from us. Unitholders may not receive cash distributions from us equal to their share of our taxable income or even equal to the actual tax due from them with respect to that income.
A unitholder's share of our taxable income, and its relationship to any distributions we make, may be affected by a variety of factors, including our economic performance, which may be affected by numerous business, economic, regulatory, legislative, competitive and political uncertainties beyond our control, and certain transactions in which we might engage. For example, we may engage in transactions that produce substantial taxable income allocations to some or all of our unitholders without a corresponding increase in cash distributions to our unitholders, such as a sale or exchange of assets, the proceeds of which are reinvested in our business or used to reduce our debt, or an actual or deemed satisfaction of our indebtedness for an amount less than the adjusted issue price of the debt. A unitholder's ratio of its share of taxable income to the cash received by it may also be affected by changes in law.
From time to time, in connection with an offering of our common units, we may state an estimate of the ratio of U.S. federal taxable income to cash distributions that a purchaser of common units in that offering may receive in a given period. These estimates depend in part on factors that are unique to the offering with respect to which the estimate is stated, so the expected ratio applicable to other common units will be different, and in many cases less favorable, than these estimates. Moreover, even in the case of common units purchased in the offering to which the estimate relates, the estimate may be incorrect, due to the uncertainties described above, challenges by the IRS to tax reporting positions which we adopt, or other factors. The actual ratio of taxable income to cash distributions could be higher or lower than expected, and any differences could be material and could materially affect the value of the common units.
27
Tax gain or loss on the disposition of our common units could be more or less than expected.
If a unitholder sells common units, the unitholder will recognize a gain or loss equal to the difference between the amount realized and that unitholder's tax basis in those common units. Because distributions in excess of a unitholder's allocable share of our net taxable income decrease such unitholder's tax basis in its common units, the amount, if any, of such prior excess distributions with respect to the units a unitholder sells will, in effect, become taxable income to a unitholder if it sells such units at a price greater than its tax basis in those units, even if the price such unitholder receives is less than its original cost. In addition, because the amount realized includes a unitholder's share of our nonrecourse liabilities, if a unitholder sells its units, a unitholder may incur a tax liability in excess of the amount of cash received from the sale.
A substantial portion of the amount realized from a unitholder's sale of our units, whether or not representing gain, may be taxed as ordinary income to such unitholder due to potential recapture items, including depreciation recapture. Thus, a unitholder may recognize both ordinary income and capital loss from the sale of units if the amount realized on a sale of such units is less than such unitholder's adjusted basis in the units. Net capital loss may only offset capital gains and, in the case of individuals, up to $3,000 of ordinary income per year. In the taxable period in which a unitholder sells its units, such unitholder may recognize ordinary income from our allocations of income and gain to such unitholder prior to the sale and from recapture items that generally cannot be offset by any capital loss recognized upon the sale of units.
Unitholders may be subject to limitation on their ability to deduct interest expense incurred by us.
In general, we are entitled to a deduction for interest paid or accrued on indebtedness properly allocable to our trade or business during our taxable year. However, our deduction for "business interest" is limited to the sum of our business interest income and 30% of our "adjusted taxable income." For the purposes of this limitation, our adjusted taxable income is computed without regard to any business interest expense or business interest income. In the case of taxable years beginning on or after January 1, 2022, our adjusted taxable income is computed by taking into account any deduction allowable for depreciation, amortization, or depletion.
If our "business interest" is subject to limitation under these rules, our unitholders will be limited in their ability to deduct their share of any interest expense that has been allocated to them. As a result, unitholders may be subject to limitation on their ability to deduct interest expense incurred by us.
Tax-exempt entities face unique tax issues from owning our common units that may result in adverse tax consequences to them.
Investment in our common units by tax-exempt entities, such as employee benefit plans and individual retirement accounts (known as IRAs) raises issues unique to them. For example, virtually all of our income allocated to organizations that are exempt from U.S. federal income tax, including IRAs and other retirement plans, will be unrelated business taxable income ("UBTI") and will be taxable to them. Tax-exempt entities should consult a tax advisor before investing in our common units.
28
Non-U.S. Unitholders will be subject to U.S. taxes and withholding with respect to their income and gain from owning our units.
Non-U.S. unitholders are generally taxed and subject to income tax filing requirements by the United States on income effectively connected with a U.S. trade or business. Income allocated to our unitholders and any gain from the sale of our units will generally be considered to be "effectively connected" with a U.S. trade or business. As a result, distributions to a non-U.S. unitholder will be subject to withholding at the highest applicable effective tax rate and a non-U.S. unitholder who sells or otherwise disposes of a unit will also be subject to U.S. federal income tax on the gain realized from the sale or disposition of that unit.
In addition to the withholding tax imposed on distributions of effectively connected income, distributions to a non-U.S. unitholder will also be subject to a 10% withholding tax on the amount of any distribution in excess of our cumulative net income. Due to the complexity of the calculation and lack of clarity in how it would apply to us, we intend to treat all of our distributions as being in excess of our cumulative net income for such purposes and subject to such 10% withholding tax. Accordingly, distributions to a non-U.S. unitholder will be subject to a combined withholding tax rate equal to the sum of the highest applicable effective tax rate and 10%.
Moreover, the transferee of an interest in a partnership that is engaged in a U.S. trade or business is generally required to withhold 10% of the "amount realized" by the transferor unless the transferor certifies that it is not a foreign person. While the determination of a partner's "amount realized" generally includes any decrease of a partner's share of the partnership's liabilities, the Treasury Regulations provide that the "amount realized" on a transfer of an interest in a publicly-traded partnership, such as our common units, will generally be the amount of gross proceeds paid to the broker effecting the applicable transfer on behalf of the transferor, and thus will be determined without regard to any decrease in that partner's share of a publicly-traded partnership's liabilities. For a transfer of interests in a publicly traded partnership that is effected through a broker on or after January 1, 2023, the obligation to withhold is imposed on the transferor's broker. Current and prospective non-U.S. unitholders should consult their tax advisors regarding the impact of these rules on an investment in our common units.
We treat each purchaser of our common units as having the same tax benefits without regard to the common units actually purchased. The IRS may challenge this treatment, which could adversely affect the value of our common units.
Because we cannot match transferors and transferees of common units, we have adopted certain methods for allocating depreciation and amortization deductions that may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to the use of these methods could adversely affect the amount of tax benefits available to our unitholders. It also could affect the timing of these tax benefits or the amount of gain from any sale of common units and could have a negative impact on the value of our common units or result in audit adjustments to a unitholder's tax returns.
We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular unit is transferred. The IRS may challenge this treatment, which could change the allocation of items of income, gain, loss and deduction among our unitholders.
We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our units on the first day of each month (the "Allocation Date"), instead of on the basis of the date a particular unit is transferred. Similarly, we generally allocate (i) certain deductions for depreciation of capital additions, (ii) gain or loss realized on a sale or other disposition of our assets and (iii) in the discretion of the general partner, any other extraordinary item of income, gain, loss or deduction based upon ownership on the Allocation Date. Treasury Regulations allow a similar monthly simplifying convention, but such regulations do not specifically authorize all aspects of our proration method. If the IRS were to challenge our proration method, we may be required to change the allocation of items of income, gain, loss and deduction among our unitholders.
29
A unitholder whose units are the subject of a securities loan (e.g., a loan to a "short seller" to cover a short sale of units) may be considered to have disposed of those units. If so, such unitholder would no longer be treated for tax purposes as a partner with respect to those units during the period of the loan and may recognize gain or loss from the disposition.
Because there are no specific rules governing the U.S. federal income tax consequence of loaning a partnership interest, a unitholder whose units are the subject of a securities loan may be considered to have disposed of the loaned units. In that case, the unitholder may no longer be treated for tax purposes as a partner with respect to those units during the period of the loan to the short seller and the unitholder may recognize gain or loss from such disposition. Moreover, during the period of the loan, any of our income, gain, loss or deduction with respect to those units may not be reportable by the unitholder and any cash distributions received by the unitholder as to those units could be fully taxable as ordinary income. Unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a securities loan are urged to consult a tax advisor to determine whether it is advisable to modify any applicable brokerage account agreements to prohibit their brokers from borrowing their units.
We have adopted certain valuation methodologies in determining a unitholder's allocations of income, gain, loss and deduction. The IRS may challenge these methodologies or the resulting allocations, which could adversely affect the value of our common units.
In determining the items of income, gain, loss and deduction allocable to our unitholders, we must routinely determine the fair market value of our assets. Although we may, from time to time, consult with professional appraisers regarding valuation matters, we make many fair market value estimates using a methodology based on the market value of our common units as a means to measure the fair market value of our assets. The IRS may challenge these valuation methods and the resulting allocations of income, gain, loss and deduction.
A successful IRS challenge to these methods or allocations could adversely affect the timing or amount of taxable income or loss being allocated to our unitholders. It also could affect the amount of gain recognized from the sale of our common units, have a negative impact on the value of our common units or result in audit adjustments to our unitholders' tax returns without the benefit of additional deductions.
Our unitholders will likely be subject to state and local taxes and income tax return filing requirements in jurisdictions where they do not live as a result of investing in our common units.
In addition to U.S. federal income taxes, our unitholders may be subject to other taxes, including foreign, state and local taxes, unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we conduct business or own property now or in the future, even if they do not live in any of those jurisdictions. Our unitholders will likely be required to file foreign, state and local income tax returns and pay state and local income taxes in some or all of these various jurisdictions. Further, our unitholders may be subject to penalties for failure to comply with those requirements.
We currently own property and conduct business in a number of states, most of which currently impose a personal income tax on individuals, and most of which also impose an income or similar tax on corporations and certain other entities. As we make acquisitions or expand our business, we may own assets or conduct business in additional states that impose similar taxes. It is our unitholders' responsibility to file all U.S. federal, foreign, state and local tax returns and pay any taxes due in these jurisdictions. Unitholders should consult with their own tax advisors regarding the filing of such tax returns, the payment of such taxes, and the deductibility of any taxes paid.

Item 1C. Cybersecurity
OpCo has entered into the Services and Secondment Agreement with Westlake and we, OpCo and Westlake have entered into the Omnibus Agreement. Pursuant to these Agreements, Westlake performs various services for us, including those related to cybersecurity. As such, this disclosure addresses our cybersecurity policies and practices, some of which are executed by Westlake under the Services and Secondment Agreement and the Omnibus Agreement.
From time to time, we and OpCo experience cybersecurity threats and attempted breaches and other incidents. Westlake classifies and tracks these events based on significance and implements remediation actions that it considers appropriate to address the risks to the Partnership and OpCo relating to such incidents. Although we and OpCo have not experienced material impacts to our business strategy, results of operations or financial condition from any such incidents in the past three years, we cannot guarantee that a material incident will not occur in the future. See "Item 1A. Risk Factors—Failure to adequately protect critical data and technology systems could materially affect our operations."
As part of our incident response planning, Westlake also maintains cross-functional response teams involving personnel outside of its cybersecurity organization, both globally and regionally, in order to be prepared to respond to an incident.
Item 2. Properties
Information regarding our properties is contained in "Item 1. Business—OpCo's Assets" and "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations."

Item 3. Legal Proceedings
In the ordinary conduct of our business, we and Westlake and Westlake's subsidiaries, including OpCo, are subject to lawsuits, investigations and claims, including environmental claims and employee related matters. See the discussions of our environmental matters contained in "Item 1. Business—Environmental" and Note 16 to the consolidated financial statements included in Item 8 of this Form 10-K. Although we cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against us, we do not believe that any currently pending legal proceeding or proceedings to which we or Westlake or any of our or Westlake's subsidiaries, including OpCo, are a party will have a material adverse effect on our business, results of operations, cash flows or financial condition.
Under the Omnibus Agreement, certain subsidiaries of Westlake have agreed to indemnify the Partnership for certain environmental and other liabilities relating to OpCo's processing facilities and related assets that occurred or existed prior to August 4, 2014.
Item 4. Mine Safety Disclosure

PART II
Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities
Our Partnership Interests
Our common units are listed and traded on the New York Stock Exchange ("NYSE") under the symbol "WLKP." As of the close of business on February 26, 2025, based upon information received from our transfer agent, there were five holders of record of our common units.
We are a publicly-traded partnership and are not subject to federal income tax. Instead, unitholders are required to report their allocable share of our income, gain, loss and deduction, regardless of whether we make distributions.
Following the Partnership's cash distribution for the second quarter of 2017, the requirement under the Partnership's partnership agreement for the conversion of all subordinated units was satisfied. As a result, effective August 30, 2017, all of the subordinated units owned by Westlake were converted into common units on a one-for-one basis and thereafter participate on terms equal with all other common units in distributions of available cash.
Selected Information from our Partnership Agreement
Set forth below is a summary of the significant provisions of our partnership agreement that relate to cash distributions, minimum quarterly distributions and incentive distribution rights.
Cash Distribution Policy
Our partnership agreement provides that our general partner will make a determination as to whether to make a distribution, but our partnership agreement does not require us to pay distributions at any time or in any amount. Instead, the board of directors adopted a cash distribution policy in connection with the closing of the IPO that sets forth our general partner's intention with respect to the distributions to be made to unitholders. Pursuant to our cash distribution policy, within 60 days after the end of each quarter, we intend to make a minimum quarterly distribution of $0.2750 per unit to the extent we have sufficient cash after establishment of cash reserves and payment of fees and expenses, including payments to our general partner and its affiliates.
The board of directors may change our cash distribution policy at any time and from time to time, and even if our cash distribution policy is not modified or revoked, the amount of distributions paid under our policy and the decision to make any distribution is determined by our general partner.
Operating Surplus and Capital Surplus
Any distribution we make is characterized as made from "operating surplus" or "capital surplus." Distributions from operating surplus are made differently than cash distributions we would make from capital surplus. Operating surplus distributions will be made to our unitholders and, if we make quarterly distributions above the first target distribution level described below, to the holder of our incentive distribution rights. We do not anticipate that we will make any distributions from capital surplus. In such an event, however, any capital surplus distribution would be made pro rata to all unitholders, but the incentive distribution rights would generally not participate in any capital surplus distributions. Any distribution of capital surplus would result in a reduction of the minimum quarterly distribution and target distribution levels and, if we reduce the minimum quarterly distribution to zero and eliminate any unpaid arrearages, thereafter capital surplus would be distributed as if it were operating surplus and the incentive distribution rights would thereafter be entitled to participate in such distributions. In determining operating surplus and capital surplus, we will only take into account our proportionate share of our consolidated subsidiaries that are not wholly owned, such as OpCo.
33
Minimum Quarterly Distribution
On July 27, 2018, the partnership agreement was amended to revise the minimum quarterly distribution thresholds for the Partnership's incentive distribution rights. The amended partnership agreement provides that the Partnership will distribute cash each quarter to all the unitholders, pro-rata, until each common unit has received a distribution of $1.2938. If cash distributions to the Partnership's unitholders exceed $1.2938 per common unit in any quarter, the Partnership's unitholders and Westlake, as the holder of the Partnership's incentive distribution rights, will receive distributions according to the percentage allocations per the amended partnership agreement. For more information on the Partnership's amended distribution allocation percentages, see Note 9, "Distributions and Net Income Per Limited Partner Unit," to the consolidated financial statements included in Item 8 of this form 10-K.
General Partner Interests and Incentive Distribution Rights
Our general partner owns a non-economic general partner interest in us, which does not entitle it to receive cash distributions. However, our general partner may in the future own common units or other equity interests in us and will be entitled to receive distributions on any such interests. Incentive distribution rights represent the right to receive increasing percentages (15.0%, 25.0% and 50.0%) of quarterly distributions from operating surplus after the target distribution levels have been achieved. Westlake currently holds the incentive distribution rights, but may transfer these rights separately from its general partner interest.
Unregistered Sales of Equity Securities
We did not have any unregistered sales of equity securities during the quarter or fiscal year ended December 31, 2024 that we have not previously reported on a Quarterly Report on Form 10-Q or a Current Report on Form 8-K.
Issuer Purchases of Equity Securities
None.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations
Overview
This Management's Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the accompanying consolidated financial statements, the notes thereto, and the other financial information appearing elsewhere in this report. The following discussion includes forward-looking statements that involve certain risks and uncertainties. See "Cautionary Statement Regarding Forward-Looking Statements" and "Item 1A. Risk Factors" included within this report.
We are a Delaware limited partnership formed by Westlake to operate, acquire and develop ethylene production facilities and related assets. On August 4, 2014, we closed our initial public offering (the "IPO") of 12,937,500 common units. In connection with the IPO, we acquired a 10.6% interest in OpCo and a 100% interest in OpCo GP, which is the general partner of OpCo. On April 29, 2015, we purchased an additional 2.7% newly-issued limited partner interest in OpCo, resulting in an aggregate 13.3% limited partner interest in OpCo effective April 1, 2015. The 12,686,115 subordinated units of the Partnership, all of which were previously owned by Westlake, were converted into common units of the Partnership on August 30, 2017. On September 29, 2017, we completed a secondary public offering of 5,175,000 common units and purchased an additional 5.0% newly-issued limited partner interest in OpCo, resulting in an aggregate 18.3% limited partner interest in OpCo effective July 1, 2017. On March 29, 2019, we completed a private placement of 2,940,818 common units and used the net proceeds to purchase an additional 4.5% interest in OpCo, effective January 1, 2019, resulting in us owning an aggregate 22.8% limited partner interest in OpCo.
Currently, our sole revenue generating asset is our 22.8% limited partner interest in OpCo, a limited partnership formed by Westlake and us in anticipation of the IPO to own and operate an ethylene production business. We control OpCo through our ownership of its general partner. Westlake retains the remaining 77.2% limited partner interest in OpCo as well as a significant interest in us through its ownership of our general partner, 40.1% of our limited partner units (consisting of 14,122,230 common units) and our incentive distribution rights. OpCo's assets include (1) two ethylene production facilities ("Petro 1" and "Petro 2" and, collectively, "Lake Charles Olefins") at Westlake's Lake Charles, Louisiana site; (2) one ethylene production facility ("Calvert City Olefins") at Westlake's Calvert City, Kentucky site; and (3) a 200-mile common carrier ethylene pipeline (the "Longview Pipeline") that runs from Mont Belvieu, Texas to Westlake's Longview, Texas facility.
How We Generate Revenue
We generate revenue primarily by selling ethylene and the resulting co-products we produce. OpCo and Westlake have entered into an ethylene sales agreement (the "Ethylene Sales Agreement") pursuant to which we generate a substantial majority of our revenue. The Ethylene Sales Agreement is a long-term, fee-based agreement with a minimum purchase commitment and includes variable pricing based on OpCo's actual feedstock and natural gas costs and estimated other costs of producing ethylene (including OpCo's estimated operating costs and a five-year average of OpCo's expected future maintenance capital expenditures and other turnaround expenditures based on OpCo's planned ethylene production capacity for the year), plus a fixed margin per pound of $0.10 less revenue from co-products sales. Pursuant to the Ethylene Sales Agreement, Westlake's obligation to pay for the annual minimum commitment (95% of OpCo's budgeted ethylene production), which is measured on an annual basis, is not reduced for a force majeure event lasting fewer than 45 consecutive days. In the event of a force majeure event, we recognize buyer deficiency fees representing fixed margin and unavoided operating and maintenance capital expenditures and maintenance expenses per pound of volume committed by Westlake during the force majeure period. In the event Westlake purchases less than its annual commitment, we recognize buyer deficiency fees representing fixed margin and all expenses and expenditures incurred per pound of volume committed but not taken by Westlake. Payment for the buyer deficiency fee is scheduled to be received by the Partnership after the conclusion of the year.
Westlake has an option to take 95% of volumes in excess of the minimum commitment on an annual basis under the Ethylene Sales Agreement if we produce more than our planned production. Under the Ethylene Sales Agreement, the price for the sale of such excess ethylene to Westlake is based on a formula similar to that used for the minimum purchase commitment, with the exception of certain fixed costs.
In addition, under the Ethylene Sales Agreement, if production costs billed to Westlake on an annual basis are less than 95% of the actual production costs incurred by OpCo during the contract year, OpCo is entitled to recover the shortfall in such production costs (proportionate to the volume sold to Westlake) in the subsequent year ("Shortfall"). The Shortfall is generally recognized during the period in which the related operating, maintenance or turnaround activities occur.

The Ethylene Sales Agreement provides that, if compliance with any law adopted or modified following our IPO results in OpCo incurring additional costs in excess of $500,000 in any contract year, OpCo is entitled to charge Westlake a monthly surcharge following efforts to mitigate the effects of such compliance.
We sell ethylene production in excess of volumes sold to Westlake, as well as all associated co-products resulting from the ethylene production, directly to third parties on either a spot or contract basis. Net proceeds (after transportation and other costs) from the sales of associated co-products that result from the production of ethylene purchased by Westlake are netted against the ethylene price charged to Westlake under the Ethylene Sales Agreement, thereby substantially reducing our exposure to fluctuations in the market prices of these co-products. During 2024, all third-party ethylene and associated co-products sales generated 16.3% of our total revenues.
Under the Services and Secondment Agreement, OpCo uses a portion of its production capacity to process purge gas for Westlake. On August 4, 2016, OpCo and Westlake entered into an amendment to the Ethylene Sales Agreement in order to provide that certain of the pricing components that make up the price for ethylene sold thereunder would be modified to reflect the portion of OpCo's production capacity that is used to process Westlake's purge gas instead of producing ethylene and to clarify that costs specific to the processing of Westlake's purge gas would be recovered under the Services and Secondment Agreement, and not the Ethylene Sales Agreement.
Please refer to Note 2 to the consolidated financial statements included in Item 8 of this form 10-K for more information on the Ethylene Sales Agreement.
How We Source Feedstock
OpCo has entered into a 12-year feedstock supply agreement (the "Feedstock Supply Agreement") with Westlake Petrochemicals LLC, a wholly owned subsidiary of Westlake, under which Westlake Petrochemicals LLC supplies OpCo with ethane and other feedstocks that OpCo uses to produce ethylene under the Ethylene Sales Agreement. For its approximately 5% merchant sales, OpCo may purchase the ethane and other feedstocks to produce ethylene and resulting co-products to sell to unrelated third parties from Westlake Petrochemicals LLC.
Please refer to Note 2 to the consolidated financial statements included in Item 8 of this form 10-K for more information on the Feedstock Supply Agreement.
How We Evaluate Operations
Our management uses a variety of financial and operating metrics to analyze our performance. These metrics are significant factors in assessing our operating results and profitability and include: (1) production volumes, (2) operating and maintenance expenses, including turnaround costs, and (3) MLP distributable cash flow and EBITDA.
Production Volumes
The amount of profit we generate primarily depends on the volumes of ethylene and resulting co-products we are able to produce at Calvert City Olefins and Lake Charles Olefins. Although Westlake has committed to purchasing minimum volumes from us under the Ethylene Sales Agreement, our results of operations are impacted by our ability to:
•produce sufficient volumes of ethylene to meet our commitments under the Ethylene Sales Agreement or recover our estimated costs through the pricing provisions of the Ethylene Sales Agreement;
•contract with third parties for the remaining uncommitted production capacity;
•add or increase capacity at our existing production facilities, or add additional production capacity via organic expansion projects and acquisitions; and
•achieve or exceed the specified yield factors for natural gas, ethane and other feedstock under the Ethylene Sales Agreement.
36
Operating Expenses, Maintenance Capital Expenditures and Turnaround Costs
Our management seeks to maximize the profitability of our operations by effectively managing operating expenses, maintenance capital expenditures and turnaround costs. Our operating expenses are comprised primarily of feedstock costs and natural gas, labor expenses (including contractor services), utility costs (other than natural gas) and turnaround and maintenance expenses. With the exception of feedstock (including natural gas) and utilities-related expenses, operating expenses generally remain relatively stable across broad ranges of production volumes but can fluctuate from period to period depending on the circumstances, particularly maintenance and turnaround activities. Our maintenance capital expenditures and turnaround costs are comprised primarily of maintenance of our ethylene production facilities and the amortization of capitalized turnaround costs. These capital expenditures relate to the maintenance and integrity of our facilities. We capitalize the costs of major maintenance activities, or turnarounds, and amortize the costs over the period until the next planned turnaround of the affected facility. We commenced the next maintenance turnaround at Petro 1 in the first quarter of 2025.
Operating expenses, maintenance capital expenditures and turnaround costs are built into the price per pound of ethylene charged to Westlake under the Ethylene Sales Agreement. Because the expenses other than feedstock costs and natural gas are based on forecasted amounts and remain a fixed component of the price per pound of ethylene sold under the Ethylene Sales Agreement for any given 12-month period, our ability to manage operating expenses, maintenance expenditures and turnaround costs may directly affect our profitability and cash flows. The impact on profitability is partially mitigated by the fact that we generally recognize any Shortfall as revenue in the period such costs and expenses are incurred. We seek to manage our operating and maintenance expenses on our ethylene production facilities by scheduling maintenance and turnarounds over time to avoid significant variability in our operating margins and minimize the impact on our cash flows, without compromising our commitment to safety and environmental stewardship. In addition, we reserve cash on an annual basis from what we would otherwise distribute to minimize the impact of turnaround costs in the year of incurrence. The purchase price under the Ethylene Sales Agreement is not designed to cover capital expenditures for expansions.
MLP Distributable Cash Flow and EBITDA
The body of accounting principles generally accepted in the United States is commonly referred to as "GAAP." For this purpose, a non-GAAP financial measure is generally defined by the Securities and Exchange Commission ("SEC") as a numerical measure of a registrant's historical or future financial performance, financial position or cash flows that (1) excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with GAAP in the statement of income, balance sheet or statement of cash flows (or equivalent statements) of the registrant; or (2) includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measure so calculated and presented. We use the non-GAAP measures of MLP distributable cash flow and EBITDA to analyze our performance. We define distributable cash flow as net income plus depreciation, amortization and disposition of property, plant and equipment, less contributions for turnaround reserves, maintenance capital expenditures and mark-to-market adjustment on derivative contracts. We define MLP distributable cash flow as distributable cash flow less distributable cash flow attributable to Westlake's noncontrolling interest in OpCo and distributions attributable to the incentive distribution rights holder. MLP distributable cash flow does not reflect changes in working capital balances. We define EBITDA as net income before interest expense, income taxes, depreciation and amortization. We use each of MLP distributable cash flow and EBITDA to analyze our performance. Fees for a buyer deficiency and Shortfall are included in net income in the periods in which they are recognized. MLP distributable cash flow and EBITDA are non-GAAP supplemental financial measures that management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess our operating performance as compared to other publicly-traded partnerships; our ability to incur and service debt and fund capital expenditures; and the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.
MLP distributable cash flow is not a substitute for the GAAP measures of net income and net cash provided by operating activities. MLP distributable cash flow has important limitations as an analytical tool because it excludes some but not all items that affect net income and net cash provided by operating activities. EBITDA is not a substitute for the GAAP measures of net income, income from operations and net cash provided by operating activities. In addition, it should be noted that companies calculate EBITDA differently and, therefore, EBITDA as presented for us may not be comparable to EBITDA reported by other companies. EBITDA has material limitations as a performance measure because it excludes interest expense, depreciation and amortization, and income taxes. Reconciliations for each of MLP distributable cash flow and EBITDA are included in the "—Results of Operations" section below.

Factors Affecting Our Business
Supply and Demand for Ethylene and Resulting Co-products
We generate a substantial majority of our revenue from the Ethylene Sales Agreement. This contract is intended to promote cash flow stability and minimize our direct exposure to commodity price fluctuations in the following ways: (1) the cost-plus pricing structure of the Ethylene Sales Agreement is expected to generate a fixed margin of $0.10 per pound, adjusting automatically for changes in feedstock costs; and (2) Westlake is committed to purchase 95% of the annual planned output, subject to a maximum commitment of 3.8 billion pounds of ethylene per year, with an option to purchase an additional 95% of actual output in excess of the planned output on a contract year basis. As a result, our direct exposure to commodity price risk is limited to approximately 5% of our total ethylene production, which is that portion sold to third parties, assuming Westlake exercises its option to purchase 95% of the over production, as well as to our co-products sales.
We also have indirect exposure to commodity price fluctuations to the extent such fluctuations affect the ethylene consumption patterns of third-party purchasers. Demand for ethylene exhibits cyclical commodity characteristics as margins earned on ethylene derivative products are influenced by changes in the balance between supply and demand, the resulting operating rates and general economic activity. While we believe we have substantially mitigated our indirect exposure to commodity price fluctuations during the term of the Ethylene Sales Agreement through the minimum purchase commitment and the cost-plus based pricing, our ability to execute our growth strategy in our areas of operation will depend, in part, on the demand for ethylene derivatives in the geographical areas served by our ethylene production facilities.
Recent Development
Petro 1 Turnaround
During the first quarter of 2025, we commenced our planned maintenance turnaround of the Petro 1 production facility.

Summary
For the year ended December 31, 2024, net income was $369.2 million on net sales of $1,135.9 million. This represents an increase in net income of $34.6 million as compared to net income of $334.6 million on net sales of $1,190.8 million for the year ended December 31, 2023. Net income attributable to the Partnership in 2024 was $62.4 million as compared to $54.3 million in 2023, an increase of $8.1 million. Income from operations was $390.4 million for 2024, as compared to $357.7 million for 2023, an increase of $32.7 million. Net sales for 2024 decreased by $54.9 million as compared to 2023 primarily due to lower ethylene sales prices to Westlake in 2024 compared to 2023, including the impact of the sale of excess quantities of ethylene in 2024 at prices that excluded certain non-variable costs of production pursuant to the Ethylene Sales Agreement, partially offset by higher ethylene and co-products sales volumes and higher third-party ethylene sales prices. Income from operations, net income and net income attributable to the Partnership for 2024 increased compared to 2023 due to higher third-party ethylene sales prices, lower ethane feedstock and natural gas costs and higher ethylene and co-products sales volumes, partially offset by lower ethylene sales prices to Westlake including the impact of the sale of excess quantities of ethylene at prices that excluded certain non-variable costs of production.
2024 Compared with 2023
Net Sales. Net sales decreased by $54.9 million, or 4.6%, to $1,135.9 million in 2024 from $1,190.8 million in 2023. The decrease in net sales in 2024 was primarily due to lower ethylene sales prices to Westlake in 2024 as compared to 2023 including the impact of the sale of excess quantities of ethylene at prices that excluded certain non-variable costs of production, partially offset by higher ethylene and co-products sales volumes and higher third-party ethylene sales prices. Lower average sales prices in 2024 contributed to a 6.6% decrease in net sales compared to 2023. Higher sales volumes in 2024 contributed to a 2.0% increase in net sales compared to 2023.
Gross Profit. Gross profit was $418.9 million in 2024, as compared to gross profit of $387.5 million in 2023. The gross profit margin was 36.9% in 2024 as compared to 32.5% in 2023. The increased gross profit margin in 2024 was primarily due to lower ethane feedstock and natural gas costs and higher third-party ethylene sales prices in 2024 as compared to 2023.
Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased by $1.3 million, or 4.4%, to $28.5 million in 2024 from $29.8 million in 2023. The decrease in 2024, as compared to 2023, was mainly attributable to lower service costs.
Interest Expense—Westlake. Interest expense remained relatively consistent at $25.7 million in 2024 compared to $26.5 million in 2023.
Other Income, net. Other income, net increased by $1.1 million to $5.3 million in 2024 from $4.2 million in 2023 primarily due to an increase in interest earned on the balance with Westlake under the Investment Management Agreement due to a higher average amount of cash invested in 2024 as compared to 2023.
Provision for Income Taxes. Provision for income taxes remained consistent at $0.8 million in 2024 as compared to $0.8 million in 2023.
MLP Distributable Cash Flow. MLP distributable cash flow increased by $4.3 million to $66.9 million in 2024 from $62.6 million in 2023. The increase in MLP distributable cash flow was primarily a result of higher net income, partially offset by higher reserves for future turnarounds.
EBITDA. EBITDA increased by $35.5 million to $507.6 million in 2024 from EBITDA of $472.1 million in 2023. The increased EBITDA, as compared to the prior year, was primarily due to higher third-party ethylene sales prices, lower ethane feedstock and natural gas costs and higher ethylene and co-products sales volumes in 2024 as compared to 2023, partially offset by lower ethylene sales prices to Westlake including the impact of the sale of excess quantities of ethylene at prices that excluded certain non-variable costs of production.

Cash Flows
Operating Activities
Operating activities provided cash of $485.0 million in 2024 as compared to cash provided by operating activities of $452.0 million in 2023. The $33.0 million increase in cash flows from operating activities was mainly due to higher income from operations, which was partially offset by a decrease in cash provided by working capital. Changes in components of working capital, which we define for the purposes of this cash flow discussion as accounts receivable, net—Westlake, accounts receivable, net—third parties, inventories, prepaid expenses and other current assets less accounts payable—Westlake, accounts payable—third parties and accrued and other liabilities, provided cash of $24.8 million in 2024 as compared to $34.4 million of cash provided in 2023, resulting in a unfavorable change of $9.6 million. The unfavorable change in working capital was mainly attributable to unfavorable changes in accrued and other liabilities and accounts payable—third parties primarily due to higher maintenance costs accrual at December 31, 2023 as compared to December 31, 2024. These unfavorable changes were partially offset by a favorable change in accounts receivable, net—third parties due to collection of a maintenance cost reimbursement and lower third party receivables at the end of 2024.
Investing Activities
Net cash used for investing activities during 2024 was $89.0 million as compared to net cash used for investing activities of $75.9 million in 2023. The $13.1 million increase in cash used for investing activities was mainly due to an increase in net cash invested under the Investment Management Agreement in 2024 as compared to 2023. During 2024, we invested $40.0 million with Westlake. During 2023, we invested $174.1 million with Westlake, and $145.0 million of such investments matured. Capital expenditures were $49.0 million in 2024 as compared to $46.8 million in 2023. Capital expenditures during 2024 and 2023 were related to projects to improve production capacity or reduce costs, maintenance and safety and environmental projects at our facilities.
Financing Activities
Net cash used for financing activities during 2024 was $396.3 million as compared to net cash used for financing activities of $382.2 million in 2023. The cash outflows during 2024 were related to distributions of $329.9 million to the noncontrolling interest retained in OpCo by Westlake and of $66.4 million to unitholders by the Partnership. The cash outflows during 2023 were related to distributions of $315.8 million to the noncontrolling interest retained in OpCo by Westlake and of $66.4 million to unitholders by the Partnership.
Liquidity and Capital Resources
Liquidity and Financing Arrangements
Pursuant to the terms of the Equity Distribution Agreement, entered in October 2018 and amended in February 2020, among the Partnership and various investment banks, the Partnership may offer and sell the Partnership's common units from time to time to or through the investment banks, as the Partnership's sales agents or as principals, having an aggregate offering amount of up to $50.0 million (the "ATM Program"). The Partnership intends to use the net proceeds of sales of the common units, if any, for general partnership purposes, which may include the funding of potential drop-downs and other acquisitions. No common units had been issued under the ATM Program as of December 31, 2024.
Based on the terms of our cash distribution policy, we expect that we will distribute to our partners most of the excess cash generated by our operations. To the extent we do not generate sufficient cash flow to fund capital expenditures, we expect to fund them primarily from external sources, including borrowing directly from Westlake, as well as future issuances of equity interests or debt.
The Partnership maintains separate bank accounts, but Westlake continues to provide treasury services on our behalf under the Omnibus Agreement. Our sources of liquidity include cash generated from operations, the OpCo Revolver, the MLP Revolver and, if necessary and possible under then current market conditions, the issuance of additional equity interests or debt. We believe that cash generated from these sources will be sufficient to meet our short-term working capital requirements and long-term capital expenditure requirements and to make quarterly cash distributions. Westlake may also provide other direct and indirect financing to us from time to time, although it is not obligated to do so.
42
In order to fund non-annual turnaround expenditures, we cause OpCo to reserve an amount for turnaround costs during each twelve-month period designed to cover future turnaround activities. Each of OpCo's ethylene production facilities requires turnaround maintenance approximately every five to eight years. By reserving additional cash annually, we intend to reduce the variability in OpCo's cash flow. Although we had previously planned to commence the next maintenance turnaround at the Petro 1 ethylene unit in the third quarter of 2024, we made the decision to defer the planned turnaround in order to maintain production and capitalize on higher average third-party ethylene sales prices during the third quarter of 2024. We commenced the planned maintenance turnaround in the first quarter of 2025. Westlake's purchase price for ethylene purchased under the Ethylene Sales Agreement includes a component (adjusted annually) designed to cover, over the long term, substantially all of OpCo's turnaround expenditures.
Our cash is generated from cash distributions from OpCo. OpCo is a restricted subsidiary under certain indentures governing Westlake's senior notes, and these restrictions limit OpCo's ability to incur additional debt, among other things. Westlake's credit facility and various indentures do not prevent OpCo from making distributions to us.
We, OpCo and Westlake are parties to an Investment Management Agreement that authorizes Westlake to invest the Partnership's and OpCo's excess cash with Westlake for durations of up to a maximum of nine months. Per the terms of the Investment Management Agreement, cash invested with Westlake earns a market return plus five basis points and Westlake provides daily availability of the invested cash to meet any liquidity needs of the Partnership or OpCo.
On January 27, 2025, the board of directors of Westlake Chemical Partners GP LLC, our general partner, approved a quarterly distribution of $0.4714 per unit payable on February 25, 2025 to unitholders of record as of February 7, 2025, which equates to a total amount of approximately $16.6 million per quarter, or approximately $66.4 million per year in aggregate, based on the number of common units outstanding on December 31, 2024. We do not have a legal or contractual obligation to pay distributions on a quarterly basis or any other basis at our minimum quarterly distribution rate or any other rate.
Capital Expenditures
Westlake has historically funded expansion capital expenditures related to Lake Charles Olefins and Calvert City Olefins. No such funding was required by OpCo during 2024, 2023 or 2022. Total capital expenditures for the years ended December 31, 2024, 2023 and 2022 were $49.0 million, $46.8 million, and $54.1 million, respectively. We expect that Westlake will loan additional cash to OpCo to fund its expansion capital expenditures in the future, but Westlake is under no obligation to do so.
Cash and Cash Equivalents
As of December 31, 2024, our cash and cash equivalents totaled $58.3 million. In addition, we have cash invested under the Investment Management Agreement and a revolving credit facility with Westlake available to supplement cash on hand, if needed, as described under "Indebtedness" below.
As described above, we, OpCo and Westlake are parties to an Investment Management Agreement that authorizes Westlake to invest the Partnership's and OpCo's excess cash with Westlake for durations of up to a maximum of nine months. The Partnership had $134.6 million of cash invested under the Investment Management Agreement at December 31, 2024.
Indebtedness
OpCo Revolver
In connection with the IPO, OpCo entered into a $600.0 million revolving credit facility with an affiliate of Westlake, as amended in June 2017, September 2018 and July 2022 (the "OpCo Revolver") that may be used to fund growth projects and working capital needs. The OpCo Revolver is scheduled to mature on July 12, 2027. On July 12, 2022, OpCo entered into the Second Amendment (the "OpCo Revolver Amendment") to the OpCo Revolver. The OpCo Revolver Amendment, among other things, extended the maturity date to July 12, 2027 and provided for the replacement of the London Interbank Offered Rate ("LIBOR") with the Secured Overnight Financing Rate, as administered by the Federal Reserve Bank of New York ("SOFR"). Borrowings under the OpCo Revolver bear interest at a variable rate of either (a) SOFR plus the Applicable Margin plus a 0.10% credit spread adjustment or, if SOFR is no longer available, (b) the Alternate Base Rate plus the Applicable Margin minus 1.0%. The Applicable Margin under the OpCo Revolver is 1.75%. As of December 31, 2024, outstanding borrowings under the OpCo Revolver totaled $22.6 million and bore interest at SOFR plus the Applicable Margin and credit spread adjustment, which is accrued in arrears quarterly.
43
MLP Revolver
In 2015, we entered into a senior, unsecured revolving credit agreement with an affiliate of Westlake, as amended in August and November 2017, March 2020 and July 2022 (the "MLP Revolver"). The MLP Revolver has a borrowing capacity of $600.0 million and is scheduled to mature on July 12, 2027. On July 12, 2022, the Partnership entered into the Fourth Amendment (the "MLP Revolver Amendment") to the MLP Revolver. The MLP Revolver Amendment, among other things, extended the maturity date to July 12, 2027 and provided for the replacement of LIBOR with SOFR as the reference rate. Borrowings under the MLP Revolver bear interest at a variable rate of either (a) SOFR plus the Applicable Margin plus a 0.10% credit spread adjustment or, if SOFR is no longer available, (b) the Alternate Base Rate plus the Applicable Margin minus 1.0%. The Applicable Margin under the MLP Revolver varies between 1.75% and 2.75%, depending on the Partnership's Consolidated Leverage Ratio. The MLP Revolver provides that we may pay all or a portion of the interest on any borrowings in kind, in which case any such amounts would be added to the principal amount of the loan. The MLP Revolver requires that we maintain a consolidated leverage ratio of either (1) during any one-year period following certain types of acquisitions (including acquisitions of additional interests in OpCo), 5.50:1.00 or less, or (2) during any other period, 4.50:1.00 or less. The MLP Revolver also contains certain other customary covenants. The repayment of borrowings under the MLP Revolver is subject to acceleration upon the occurrence of an event of default. As of December 31, 2024, the outstanding borrowings under the MLP Revolver totaled $377.1 million and bore interest at SOFR plus the Applicable Margin and credit spread adjustment, which is accrued in arrears quarterly. We intend to use the MLP Revolver to purchase additional limited partnership interests in OpCo in the future, in the event OpCo desires to sell such additional interests to us, for other acquisitions and for general partnership purposes.
Contractual Obligations and Commercial Commitments
The Partnership's material cash requirements for contractual obligations and commercial commitments in the near term (next 12 months) and the long-term period (2026 and thereafter) include repayment of long-term debt, interest payments, operating leases and purchase obligations.
Debt Obligations and Interest Payments. As of December 31, 2024, we had $25.8 million of debt related interest expense due within the near term, and debt obligations of $399.7 million and related interest expense of $39.4 million due over the long-term period, respectively. All $399.7 million of our outstanding debt matures in 2027. See Note 8, "Long-Term Debt," in the Notes to Consolidated Financial Statements in Item 8 of this form 10-K for further information on our debt obligations and the expected timing of future principal and interest payments.
Operating Leases. As of December 31, 2024, there was $1.7 million in operating lease obligations due within the near term and $2.2 million due over the long-term period related to noncancelable operating leases with respect to rail cars that are subleased to OpCo.
Purchase Obligations. Purchase obligations include agreements to purchase goods and services that are enforceable and legally binding and that specify all significant terms, including a minimum quantity and price. As of December 31, 2024, we had $128.7 million of enforceable and legally binding purchase commitments due within the near term, and none due over the long-term period. Additionally, we are party to various agreements to purchase goods and services, including the Services and Secondment Agreement, in the ordinary course of our business, as well as various agreements related to our capital projects.
Critical Accounting Policies and Estimates
Critical accounting policies are those that are important to our financial condition and require management's most difficult, subjective or complex judgments. Different amounts would be reported under different operating conditions or under alternative assumptions. We have evaluated the accounting policies used in the preparation of the accompanying consolidated financial statements and related notes and believe those policies are reasonable and appropriate. Our significant accounting policies are summarized in Note 1 in the Notes to Consolidated Financial Statements in Item 8 of this form 10-K.
Critical accounting estimates are those estimates made in accordance with GAAP that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on our financial condition or results of operations. Our more critical accounting estimates include those related to long-lived assets, fair value estimates, goodwill impairment and environmental and legal obligations. Inherent in such estimates are certain key assumptions. We periodically update the estimates used in the preparation of the financial statements based on our latest assessment of the current and projected business and general economic environment. We believe the following to be our most critical accounting estimates required for the preparation of our financial statements.
44
Long-Lived Assets. Key estimates related to long-lived assets include useful lives, recoverability of carrying values and existence of any retirement obligations. Such estimates could be significantly modified. The carrying values of long-lived assets could be impaired by significant changes or projected changes in supply and demand fundamentals (which would have a negative impact on operating rates or margins), new technological developments, new competitors with significant raw material or other cost advantages, adverse changes associated with the U.S. and world economies, the cyclical nature of the chemical and refining industries and uncertainties associated with governmental actions.
We evaluate long-lived assets for potential impairment indicators whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, including when negative conditions such as significant current or projected operating losses exist. Our judgments regarding the existence of impairment indicators are based on legal factors, market conditions and the operational performance of our businesses. Actual impairment losses incurred could vary significantly from amounts estimated. Long-lived assets assessed for impairment are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Additionally, future events could cause us to conclude that impairment indicators exist and that associated long-lived assets of our businesses are impaired. Any resulting impairment loss could have a material adverse impact on our financial condition and results of operations.
The estimated useful lives of long-lived assets range from three to 40 years. Depreciation and amortization of these assets, including amortization of deferred turnaround costs, under the straight-line method over their estimated useful lives totaled $111.9 million, $110.2 million and $121.1 million in 2024, 2023 and 2022, respectively. If the useful lives of the assets were found to be shorter than originally estimated, depreciation or amortization charges would be accelerated.
We defer the costs of planned major maintenance activities, or turnarounds, and amortize the costs over the period until the next planned turnaround of the affected unit. Total costs deferred on turnarounds were $21.5 million, $30.9 million and $6.7 million in 2024, 2023 and 2022, respectively. Amortization of previously deferred turnaround costs was $25.1 million, $25.4 million and $26.0 million in 2024, 2023 and 2022, respectively. As of December 31, 2024, deferred turnaround costs, net of accumulated amortization, totaled $129.6 million. Expensing turnaround costs as incurred would likely result in greater variability of our quarterly operating results and would adversely affect our financial position and results of operations.
Additional information concerning long-lived assets and related depreciation and amortization appears in Notes 5 and 7 to the consolidated financial statements included in Item 8 of this form 10-K.
Fair Value Estimates. We develop estimates of fair value to allocate the purchase price paid to acquire a business to the assets acquired and liabilities assumed in an acquisition, to assess impairment of long-lived assets and goodwill and to record derivative instruments. We use all available information to make these fair value determinations, including the engagement of third-party consultants. We record all derivative instruments at fair value. The fair value of the financial instruments is estimated using quoted market prices in active markets and observable market-based inputs or unobservable inputs that are corroborated by market data when active markets are not available or unobservable inputs that are not corroborated by market data. There were no derivative positions during the years ended December 31, 2024, 2023 and 2022. However, we may enter into derivative arrangements in the future.
Goodwill. Goodwill is evaluated for impairment when events or changes in circumstances indicate the fair value of a reporting unit with goodwill has been reduced below its carrying value, and otherwise at least annually. At December 31, 2024, recorded goodwill was $5.8 million, all of which was associated with the acquisition of the Longview Pipeline as part of the past acquisition of Westlake's Longview production facilities. We perform our annual impairment assessment in the fourth quarter. We may elect to perform an optional qualitative assessment to determine whether a quantitative impairment analysis is required. The qualitative assessment considers factors such as macroeconomic conditions, industry and market considerations, cost factors related to raw materials and labor, current and projected financial performance, changes in management or strategy, and market capitalization. Alternatively, we may unconditionally elect to bypass the qualitative assessment and perform a quantitative goodwill impairment assessment in any period. Significant assumptions used in the discounted cash flow projection impairment assessment for goodwill include future sales volumes based on production capacities. The future cash flows are discounted to present value using a discount rate. The significant assumptions used in determining the fair value of the reporting unit using the market value methodology include the determination of appropriate market comparables and the estimated multiples of EBITDA a willing buyer is likely to pay. We elected to perform the qualitative assessment in the fourth quarter of 2024 and concluded that it is more likely than not that the fair value of the reporting unit exceeds the carrying amount and, as such, the quantitative impairment test was not required.
45
Environmental and Legal Obligations. We consult with various professionals to assist us in making estimates relating to environmental costs and legal proceedings. We accrue an expense when we determine that it is probable that a liability has been incurred and the amount is reasonably estimable. While we believe that the amounts recorded in the accompanying consolidated financial statements related to these contingencies are based on the best estimates and judgments available, the actual outcomes could differ from our estimates. Additional information about certain legal proceedings and environmental matters appears in "Item 1. Business—Environmental" and in Note 16 to the consolidated financial statements included in Item 8 of this form 10-K.
The Partnership has conditional asset retirement obligations for the removal and disposal of hazardous materials and the remediation of the cause of any such release from certain of the Partnership's manufacturing facilities. However, no asset retirement obligations have been recognized because the fair value of the conditional legal obligation cannot be measured due to the indeterminate settlement date of the obligation. Settlement of these conditional asset retirement obligations is not expected to have a material adverse effect on the Partnership's financial condition, results of operations or cash flows in any individual reporting period.
Recent Accounting Pronouncements
See Note 1 to the consolidated financial statements included in Item 8 of this form 10-K for a full description of recent accounting pronouncements, including expected dates of adoption and estimated effects on results of operations and financial condition, which is incorporated herein by reference.
Item 7A. Quantitative and Qualitative Disclosures about Market Risk
Commodity Price Risk
A substantial portion of the Partnership's products and raw materials are commodities whose prices fluctuate as market supply and demand fundamentals change. However, our direct exposure to commodity price risk is limited to approximately 5% of our total ethylene production, which is the portion sold to third parties. We believe we have substantially mitigated our indirect exposure to commodity price fluctuation during the term of the Ethylene Sales Agreement through the minimum purchase commitment and the cost-plus based pricing. Additionally, we may use derivative instruments to reduce price volatility risk on feedstocks and ethylene associated with the production and sales to third parties. There were no derivative positions during the years ended December 31, 2024, 2023 and 2022.
Interest Rate Risk
We are exposed to interest rate risk with respect to our outstanding debt, all of which is variable rate debt. As of December 31, 2024, we had variable rate debt of $399.7 million outstanding, all of which was owed to wholly-owned subsidiaries of Westlake. On July 12, 2022, OpCo entered into the OpCo Revolver Amendment. The OpCo Revolver Amendment, among other things, provided for the replacement of LIBOR with SOFR as the reference rate. Borrowings under the OpCo Revolver bear interest at a variable rate of either (a) SOFR plus the Applicable Margin plus a 0.10% credit spread adjustment or, if SOFR is no longer available, (b) the Alternate Base Rate plus the Applicable Margin minus 1.0%. The Applicable Margin under the OpCo Revolver is 1.75%. On July 12, 2022, the Partnership entered into the MLP Revolver Amendment. The MLP Revolver Amendment, among other things, provided for the replacement of LIBOR with SOFR as the reference rate. Borrowings under the MLP Revolver bear interest at a variable rate of either (a) SOFR plus the Applicable Margin plus a 0.10% credit spread adjustment or, if SOFR is no longer available, (b) the Alternate Base Rate plus the Applicable Margin minus 1.0%. The Applicable Margin under the MLP Revolver varies between 1.75% and 2.75%, depending on the Partnership's Consolidated Leverage Ratio. The weighted average variable interest rate of our debt as of December 31, 2024 was 6.4%. We will continue to be subject to interest rate risk with respect to our variable rate debt as well as the risk of higher interest cost if and when this debt is refinanced. A hypothetical increase in our average interest rate on variable rate debt by 100 basis points would increase our annual interest expense by approximately $4.0 million, of which $3.8 million would relate to the MLP Revolver and $0.2 million would relate to the OpCo Revolver based on the December 31, 2024 debt balance.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
The management of Westlake Chemical Partners LP (the "Partnership") is responsible for establishing and maintaining adequate internal control over financial reporting. The Partnership's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.
The management of the Partnership assessed the effectiveness of the Partnership's internal control over financial reporting as of December 31, 2024. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework (2013). Based on its assessment, the Partnership's management has concluded that the Partnership's internal control over financial reporting was effective as of December 31, 2024 based on those criteria.
PricewaterhouseCoopers LLP, the independent registered public accounting firm that audited the financial statements included in this Annual Report on Form 10-K, has also audited the effectiveness of internal control over financial reporting as of December 31, 2024 as stated in their report that appears on the following page.

Report of Independent Registered Public Accounting Firm
To the Partners of Westlake Chemical Partners LP and
Board of Directors of Westlake Chemical Partners GP LLC
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Westlake Chemical Partners LP and its subsidiaries (the "Partnership") as of December 31, 2024 and 2023, and the related consolidated statements of operations, of changes in equity and of cash flows for each of the three years in the period ended December 31, 2024, including the related notes (collectively referred to as the "consolidated financial statements"). We also have audited the Partnership's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Partnership as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Partnership maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Partnership's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 8. Our responsibility is to express opinions on the Partnership's consolidated financial statements and on the Partnership's internal control over financial reporting 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 Partnership in accordance with the U.S. 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, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements 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. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
49
Definition and Limitations of Internal Control over Financial Reporting
A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions 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 generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) 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 matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Revenue from the Ethylene Sales Agreement
As described in Notes 2 and 11 to the consolidated financial statements, the Partnership recognized net sales to Westlake Corporation ("Westlake") of $951 million for the year ended December 31, 2024. The Ethylene Sales Agreement requires Westlake to purchase a minimum volume of ethylene each year equal to 95% of Westlake Chemical OpCo LP's ("OpCo") planned ethylene production per year, subject to certain exceptions and a maximum commitment of 3.8 billion pounds per year. So long as Westlake is not in default under the Ethylene Sales Agreement, if OpCo's actual production exceeds planned production, Westlake has the option to purchase up to 95% of the excess production (the "Excess Production Option"). The fee for each pound of ethylene purchased by Westlake from OpCo up to the minimum commitment will equal (i) the actual price OpCo pays Westlake to purchase ethane, (ii) plus the actual price OpCo pays Westlake to purchase natural gas, (iii) plus OpCo's estimated operating costs divided by OpCo's planned ethylene production for the year, (iv) plus a five-year average of OpCo's expected future maintenance capital expenditures and other turnaround expenditures divided by OpCo's planned ethylene production capacity for the year, (v) less the proceeds received by OpCo from the sale of co-products associated with producing the ethylene purchased by Westlake, (vi) plus a $0.10 per pound margin. The fee for the Excess Production Option, if exercised, equals OpCo's estimated variable operating costs of producing the incremental ethylene, net of revenues from co-products sales plus a $0.10 per pound margin. The result of the fee structure is that OpCo should generally recover the portion of its total operating costs and maintenance capital expenditures and other turnaround expenditures corresponding to the portion of OpCo's aggregate production that is purchased by Westlake. Any shortfall in recovery of such costs is generally recognized during the period in which the related operating, maintenance or turnaround activities occur and is recoverable from Westlake in the subsequent year. Under the Ethylene Sales Agreement, if production costs billed to Westlake on an annual basis are less than 95% of the actual production costs incurred by OpCo during the contract year, OpCo is entitled to recover the shortfall in such production costs (proportionate to the volume sold to Westlake) in the subsequent year ("Shortfall"). In the event Westlake purchases less than its annual commitment, the Partnership recognizes buyer deficiency fees representing fixed margin and all expenses and expenditures incurred per pound of volume committed but not taken by Westlake. Westlake exercised the Excess Production Option in 2024.
The principal considerations for our determination that performing procedures relating to revenue from the Ethylene Sales Agreement is a critical audit matter are the significant audit effort in performing procedures and evaluating the calculation of the fee for each pound of ethylene.
50
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the accuracy of the fees used to determine revenue from the Ethylene Sales Agreement. These procedures also included, among others (i) testing the completeness and accuracy of underlying inputs used in the fee for each pound of ethylene purchased by Westlake, buyer deficiency fee and Shortfall calculations; and (ii) testing the accuracy of the volume of ethylene purchased by Westlake as part of the Ethylene Sales Agreement.

WESTLAKE CHEMICAL PARTNERS LP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(in thousands of dollars, except unit amounts and per unit data)
1. Description of Business and Significant Accounting Policies
Description of Business
Westlake Chemical Partners LP (the "Partnership") is a Delaware limited partnership formed in March 2014 to operate, acquire and develop ethylene production facilities and related assets. On August 4, 2014, the Partnership completed its initial public offering (the "IPO") of 12,937,500 common units representing limited partner interests.
In connection with the IPO, the Partnership acquired a 10.6 % limited partner interest in Westlake Chemical OpCo LP ("OpCo") and a 100 % interest in Westlake Chemical OpCo GP LLC ("OpCo GP"), which is the general partner of OpCo. OpCo owns three ethylene production facilities and one common carrier ethylene pipeline (collectively, the "Contributed Assets"). Since the IPO, the Partnership has periodically purchased additional limited partner interest in OpCo. Most recently, on March 29, 2019, the Partnership purchased an additional 4.5 % newly-issued limited partner interest in OpCo for approximately $201,445 , resulting in an aggregate 22.8 % limited partner interest in OpCo, effective January 1, 2019. The remaining 77.2 % limited partner interest in OpCo is owned by Westlake Corporation. References to "Westlake" refer collectively to Westlake Corporation and its subsidiaries, other than the Partnership, OpCo and OpCo GP.
OpCo and Westlake entered into an ethylene sales agreement (the "Ethylene Sales Agreement") pursuant to which the Partnership generates a substantial majority of its revenue. For more information, see Note 2.
Basis of Presentation
The accompanying consolidated financial statements have been prepared in conformity with the accounting principles generally accepted in the United States.
The Partnership holds a 22.8 % limited partner interest and the entire non-economic general partner interest in OpCo. The remaining 77.2 % limited partner interest in OpCo is owned directly by Westlake, which has no rights to direct the activities that most significantly impact the economic performance of OpCo. As a result of the fact that substantially all of OpCo's activities are conducted on behalf of Westlake, and the fact that OpCo exhibits disproportionality of voting rights to economic interest, OpCo was deemed to be a variable interest entity. The Partnership, through its ownership of OpCo's general partner, has the power to direct the activities that most significantly impact the economic performance of OpCo, and it also has the obligation or right to absorb losses or receive benefits from OpCo that could potentially be significant to OpCo. As such, the Partnership was determined to be OpCo's primary beneficiary and therefore consolidates OpCo's results of operations and financial position. The Partnership's operations consist exclusively of the variable interest entity's operations and, as such, no additional variable interest entity disclosures are considered necessary. Westlake's retained interest of 77.2 % is recorded as noncontrolling interest in the Partnership's consolidated financial statements.

Cash and Cash Equivalents
Cash equivalents consist of highly liquid investments that are readily convertible into cash and have a maturity of three months or less at the date of acquisition.
Allowance for Credit Losses
The determination of the allowance for credit losses is based on estimation of the amount of accounts receivable that the Partnership believes are unlikely to be collected. Estimating this amount requires analysis of the financial strength of the Partnership's customers, the use of historical experience, the Partnership's accounts receivable aged trial balance, customer specific collectability analysis and an evaluation of economic conditions. The allowance for credit losses is reviewed quarterly. Past due balances over 90 days and high risk accounts, as determined by the analysis of financial strength of customers, are reviewed individually for collectability.
Inventories
Inventories primarily include product, material and supplies. Inventories are stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out ("FIFO") or average method.
Property, Plant and Equipment
Property, plant and equipment are carried at cost, net of accumulated depreciation. Cost includes expenditures for improvements and betterments that extend the useful lives of the assets and interest capitalized on significant capital projects.
Interest expense is capitalized for qualifying assets under construction. Capitalized interest costs are included in property, plant and equipment and are depreciated over the useful life of the related asset. Capitalized interest was $197 , $164 and $80 for the years ended December 31, 2024, 2023 and 2022, respectively. Repair and maintenance costs are charged to operations as incurred. Gains and losses on the disposal or retirement of property, plant and equipment are reflected in the statement of operations when the assets are sold or retired.
The accounting guidance for asset retirement obligations requires the recording of liabilities equal to the fair value of asset retirement obligations and corresponding additional asset costs, when there is a legal asset retirement obligation as a result of existing or enacted law, statute or contract. The Partnership has conditional asset retirement obligations for the removal and disposal of hazardous materials from certain of the Partnership's manufacturing facilities. However, no asset retirement obligations have been recognized because the fair value of the conditional legal obligation cannot be measured due to the indeterminate settlement date of the obligation. Settlement of these conditional asset retirement obligations is not expected to have a material adverse effect on the Partnership's financial condition, results of operations or cash flows in any individual reporting period.
Depreciation is provided by utilizing the straight-line method over the estimated useful lives of the assets as follows:

Impairment of Long-Lived Assets
The accounting guidance for the impairment or disposal of long-lived assets requires that the Partnership assess long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, including when negative conditions such as significant current or projected operating losses exist. Other factors considered by the Partnership when determining if an impairment assessment is necessary include, but are not limited to, significant changes or projected changes in supply and demand fundamentals (which would have a negative impact on operating rates or margins), new technological developments, new competitors with significant raw material or other cost advantages, adverse changes associated with the United States and world economies and uncertainties associated with governmental actions. Long-lived assets assessed for impairment are grouped by asset group, the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net undiscounted cash flows expected to be generated by the asset group. Assets are considered to be impaired if the carrying amount of an asset exceeds the future undiscounted cash flows. The impairment recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or estimated fair value less costs to sell.
Impairment of Goodwill
The accounting guidance requires that goodwill be tested for impairment at least annually, or when events or changes in circumstances indicate the fair value of a reporting unit with goodwill has been reduced below its carrying amount. The impairment test for the recorded goodwill was performed in the fourth quarter of 2024 and did not indicate impairment of the goodwill. As of December 31, 2024, the Partnership's recorded goodwill was $5,814 . See Note 6 for more information on the Partnership's annual goodwill impairment test.
Turnaround Costs
The Partnership accounts for turnaround costs under the deferral method. Turnarounds are the scheduled and required shutdowns of specific operating units in order to perform planned major maintenance activities. The costs related to the significant overhaul and refurbishment activities include maintenance materials, parts and direct labor costs. The costs of the turnaround are deferred when incurred at the time of the turnaround and amortized (within depreciation and amortization) on a straight-line basis until the next planned turnaround, which typically ranges from to years. Deferred turnaround costs are presented as a component of deferred charges and other assets, net. The cash outflows related to these costs are included in operating activities in the consolidated statement of cash flows.
Concentration of Credit Risk
Revenue Recognition
Revenue is recognized when OpCo transfers control of inventories to customers. Amounts recognized as revenues reflect the consideration to which OpCo expects to be entitled in exchange for those inventories. The Partnership and OpCo incorporate production volume and production cost forecasts in the estimated transaction prices from sales to Westlake under the Ethylene Sales Agreement.
The Partnership recognizes revenue and accounts receivable upon transferring control of inventories to its customers. Ethylene sold to Westlake under the Ethylene Sales Agreement is transferred to Westlake immediately after production and recognized in sales. Control of inventories sold to third parties generally transfers upon shipment to the customer. The Partnership excludes taxes collected on behalf of customers from the estimated contract price. Provisions for discounts, rebates and returns are incorporated in the estimate of variable consideration and reflected as reduction to revenue in the same period as the related sales.
The Partnership does not disclose the value of unsatisfied performance obligations because its contracts with customers (1) have an original expected duration of one year or less or (2) have only variable consideration that is calculated based on market prices at a specified date and is allocated to wholly unsatisfied performance obligations.

WESTLAKE CHEMICAL PARTNERS LP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(in thousands of dollars, except unit amounts and per unit data)
The Partnership generates a substantial majority of its revenue from sales to Westlake under the Ethylene Sales Agreement. The Ethylene Sales Agreement is intended to generate a long-term, fixed cash margin per pound. See Note 2 for a description of the terms of the Ethylene Sales Agreement. The Partnership's direct commodity price risk is limited to the sales to third parties. See the Partnership's consolidated statements of operations for the disaggregation of net sales to Westlake and net sales to third parties.
Transportation and Freight
Amounts billed to customers for freight and handling costs on outbound shipments are included in net sales in the consolidated statements of operations. Transportation and freight costs incurred by the Partnership on outbound shipments are included in cost of sales in the consolidated statements of operations.
Environmental Costs
Income Taxes
The Partnership is a limited partnership and is treated as a partnership for U.S. federal income tax purposes and, therefore, is not liable for entity-level federal income taxes. The Partnership is, however, subject to state and local income taxes. Deferred tax expense or benefit is the result of changes in the deferred tax assets and liabilities during the period. Valuation allowances are recorded against deferred tax assets when it is considered more likely than not that the deferred tax assets will not be realized on a separate tax return basis.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual results could differ from those estimates.
Other Comprehensive Income
The Partnership has not reported consolidated statements of comprehensive income for the years ended December 31, 2024, 2023 and 2022 due to immateriality of the components of other comprehensive income.
Recently Issued Accounting Pronouncements
Income Taxes (ASU No. 2023-09)
In December 2023, the Financial Accounting Standards Board ("FASB") issued an accounting standards update to require additional tax disclosures under Topic 740 primarily related to the rate reconciliation and income taxes paid disclosures. The amendments in this update will be effective for fiscal years beginning after December 15, 2024 and are to be applied on a prospective basis. Retrospective application is also permitted. The update is not expected to have a material impact on the Partnership's disclosures.

Disaggregation of Income Statement Expenses (ASU No. 2024-03)
In November 2024, the FASB issued an accounting standards update requiring public entities to disclose on an annual and interim basis detailed information about the types of expenses in relevant expense captions presented on the face of the income statement, including amounts for inventory purchases, employee compensation, depreciation and amortization of intangible assets and a qualitative description for remaining amounts not separately disaggregated. Additionally, the update requires disclosure of total selling expenses, and in annual periods, an entity's definition of selling expenses. The amendments in this update are effective for annual reporting periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027 and are to be applied either prospectively or retrospectively. Early adoption is permitted. The Partnership is currently evaluating the impact of the update on the disclosures in the Partnership's financial statements.
Recently Adopted Accounting Standard
Segment Reporting (ASU No. 2023-07)
In November 2023, the FASB issued an accounting standards update requiring public entities to disclose on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker ("CODM"), the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. The update also requires that a public entity that has a single reportable segment provide all disclosures required by the update as well as all existing segment disclosures in Topic 280. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 and are to be applied retrospectively to all prior periods presented in the financial statements. Early adoption is permitted. The Partnership adopted this accounting standard effective for the annual 2024 financial statements, and the adoption resulted in additional segment disclosures (see Note 17) and will result in additional segment disclosures in the Partnership's interim period financial statements thereafter.
2. Agreements with Westlake and Related Parties
Ethylene Sales Agreement
OpCo has entered into an ethylene sales agreement with Westlake (the "Ethylene Sales Agreement") with an initial term of 12 years. The Ethylene Sales Agreement requires Westlake to purchase a minimum volume of ethylene each year equal to 95 % of OpCo's planned ethylene production per year (the "Minimum Commitment"), subject to certain exceptions and a maximum commitment of 3.8 billion pounds per year. So long as Westlake is not in default under the Ethylene Sales Agreement, if OpCo's actual production exceeds planned production, Westlake has the option to purchase up to 95 % of the excess production (the "Excess Production Option").
The fee for each pound of ethylene purchased by Westlake from OpCo up to the Minimum Commitment in any calendar year will equal:
•the actual price OpCo pays Westlake to purchase ethane (or other feedstock, such as propane, if applicable) to produce each pound of ethylene, subject to a specified cap and a floor on the amount of feedstock that should be needed to produce each pound of ethylene; plus
•the actual price OpCo pays Westlake to purchase natural gas to produce each pound of ethylene, subject to a specified cap and a floor on the amount of natural gas that should be needed to produce each pound of ethylene; plus
•OpCo's estimated operating costs (including selling, general and administrative expenses), divided by OpCo's planned ethylene production for the year (in pounds); plus
•a five-year average of OpCo's expected future maintenance capital expenditures and other turnaround expenditures, divided by OpCo's planned ethylene production capacity for the year (in pounds); less
•the proceeds (on a per pound of ethylene basis) received by OpCo from the sale of co-products (including, but not limited to, propylene, crude butadiene, pyrolysis gasoline and hydrogen) associated with producing the ethylene purchased by Westlake; plus
•a $0.10 per pound margin.
The fee for the Excess Production Option, if exercised, equals OpCo's estimated variable operating costs of producing the incremental ethylene, net of revenues from co-products sales plus a $0.10 per pound margin.
60
WESTLAKE CHEMICAL PARTNERS LP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(in thousands of dollars, except unit amounts and per unit data)
The estimated operating costs and the expected future maintenance capital expenditures and other turnaround expenditures will be adjusted at the end of each year, to be applicable for the fee for the next calendar year, to reflect certain changes in forecasted costs.
Under the Ethylene Sales Agreement OpCo has the option to curtail up to approximately 5 % of its ethylene production annually in the event OpCo reasonably determines that its sales of such ethylene to third parties during the relevant period would be uneconomic.
Certain of the pricing components that make up the price for ethylene sold under the Ethylene Sales Agreement are modified to reflect the portion of OpCo's production capacity that is used to process Westlake's purge gas instead of producing ethylene. Costs specific to the processing of Westlake's purge gas are recovered under the Services and Secondment Agreement (as described below), and not the Ethylene Sales Agreement.
Pursuant to the Ethylene Sales Agreement, Westlake's obligation to pay for the annual minimum commitment (95 % of OpCo's budgeted ethylene production), which is measured on an annual basis, is not reduced for a force majeure event lasting fewer than 45 consecutive days. In the event of a force majeure event, the Partnership recognizes buyer deficiency fees representing fixed margin and unavoided operating and maintenance capital expenditures and maintenance expenses per pound of volume committed by Westlake during the force majeure period. In the event Westlake purchases less than its annual commitment, the Partnership recognizes buyer deficiency fees representing fixed margin and all expenses and expenditures incurred per pound of volume committed but not taken by Westlake. Payment for the buyer deficiency fee is scheduled to be received by the Partnership after the conclusion of the year in which the force majeure event occurred.
The result of the fee structure is that OpCo should generally recover the portion of its total operating costs and maintenance capital expenditures and other turnaround expenditures corresponding to the portion of OpCo's aggregate production that is purchased by Westlake. Any shortfall in recovery of such costs is generally recognized during the period in which the related operating, maintenance or turnaround activities occur and is recoverable from Westlake in the subsequent year. Under the Ethylene Sales Agreement, if production costs billed to Westlake on an annual basis are less than 95 % of the actual production costs incurred by OpCo during the contract year, OpCo is entitled to recover the shortfall in such production costs (proportionate to the volume sold to Westlake) in the subsequent year ("Shortfall").
The Ethylene Sales Agreement provides that, if compliance with any law adopted or modified following the IPO results in OpCo incurring additional costs in excess of $500 in any contract year, OpCo is entitled to charge Westlake a monthly surcharge following efforts to mitigate the effects of such matter.
The Ethylene Sales Agreement has an initial term extending until December 31, 2026 and automatically renews thereafter for successive 12 -month terms unless terminated.
Feedstock Supply Agreement
OpCo has entered into a feedstock supply agreement with Westlake, pursuant to which Westlake sells to OpCo ethane and other feedstock in amounts sufficient for OpCo to produce the ethylene to be sold under the Ethylene Sales Agreement (the "Feedstock Supply Agreement"). The Feedstock Supply Agreement provides that OpCo may obtain feedstock from Westlake based on Westlake's total cost of purchasing and delivering the feedstock, including applicable transportation, storage and other costs. Title and risk of loss for all feedstock purchased by OpCo through the Feedstock Supply Agreement passes to OpCo upon delivery to one of three delivery points described in the Feedstock Supply Agreement.
The Feedstock Supply Agreement has an initial term extending until December 31, 2026 and automatically renews thereafter for successive 12 -month terms unless terminated by either party; provided, however, that such agreement can only be renewed in the event the Ethylene Sales Agreement is renewed simultaneously. The Feedstock Supply Agreement may, in certain circumstances, terminate concurrently with the termination of the Ethylene Sales Agreement.
Services and Secondment Agreement
OpCo has entered into a Services and Secondment Agreement with Westlake, pursuant to which OpCo provides Westlake with certain services required for the operation of Westlake's facilities; and Westlake provides OpCo with comprehensive operating services for OpCo's facilities, ranging from services relating to the maintenance and operations of the common facilities necessary for the operation of OpCo's units, to making available certain shared utilities such as electricity and natural gas that are necessary for the operation of OpCo's units. Westlake also seconds employees to OpCo to allow OpCo to operate its facilities. Such seconded employees are under the control of OpCo while they work on OpCo's facilities.
61
WESTLAKE CHEMICAL PARTNERS LP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(in thousands of dollars, except unit amounts and per unit data)
The Services and Secondment Agreement has an initial 12 -year term. The Services and Secondment Agreement may be renewed thereafter upon agreement of the parties and shall automatically terminate if the Ethylene Sales Agreement terminates under certain circumstances. Westlake and OpCo each can terminate the Services and Secondment Agreement under certain circumstances, including if the other party materially defaults on the performance of its obligations and such default continues for a 30 -day period.
Site Lease Agreements
OpCo has entered into two site lease agreements with Westlake pursuant to which Westlake leases to OpCo the real property underlying Lake Charles Olefins and Calvert City Olefins and grants OpCo rights to access and use certain other portions of Westlake's ethylene production facilities that are necessary to operate OpCo's production facilities. OpCo owes Westlake one dollar per site per year. The site lease agreements each have a term of 50 years. Each of the site lease agreements may be renewed if agreed by the parties.
Omnibus Agreement
The Partnership has entered into an Omnibus Agreement with Westlake that addresses (1) Westlake's indemnification of the Partnership for certain matters, including environmental and tax matters, (2) the provision by Westlake of certain management and other general and administrative services to the Partnership and its general partner and (3) the Partnership's reimbursement to Westlake for such services. The Omnibus Agreement also addresses Westlake's right of first refusal on any proposed transfer of the ethylene production facilities that serve Westlake's other facilities and Westlake's right of first refusal on any proposed transfer of the Partnership's equity interests in OpCo.
Exchange Agreement
OpCo and Westlake are parties to an exchange agreement, which continues on an annual basis, unless and until terminated by either party. Under the exchange agreement, OpCo may require Westlake to deliver up to 200 million pounds of ethylene for OpCo per year from the Site Leases to an ethylene hub in Mt. Belvieu, Texas, for which OpCo would be required to pay an exchange fee of $0.006 per pound.
OpCo Partnership Agreement
The Partnership, OpCo GP and Westlake are parties to an agreement of limited partnership for OpCo (the "OpCo LP Agreement"). The OpCo LP Agreement governs the ownership and management of OpCo and designates OpCo GP as the general partner of OpCo. OpCo GP generally has complete authority to manage OpCo's business and affairs. The Partnership controls OpCo GP, as its sole member, subject to certain approval rights held by Westlake.
Investment Management Agreement
The Partnership, OpCo and Westlake are parties to an Investment Management Agreement that authorizes Westlake to invest the Partnership and OpCo's excess cash with Westlake for durations of up to a maximum of nine months . Per the terms of the Investment Management Agreement, the Partnership earns a market return plus five basis points and Westlake provides daily availability of the invested cash to meet any liquidity needs of the Partnership or OpCo. The Partnership had $134,557 of invested cash under the Investment Management Agreement at December 31, 2024.

| 2024 | 2023 | |||||||||||||
| OpCo Revolver | $ | $ | ||||||||||||
| MLP Revolver | ||||||||||||||
| Long-term debt payable to Westlake | $ | $ | ||||||||||||
On August 4, 2014, OpCo entered into a $600,000 senior unsecured revolving credit facility agreement with Westlake (as subsequently amended, the "OpCo Revolver"). On July 12, 2022, OpCo entered into the Second Amendment (the "OpCo Revolver Amendment") to the OpCo Revolver. Prior to the OpCo Revolver Amendment, the OpCo Revolver bore interest at the London Interbank Offered Rate ("LIBOR") plus 2.0 %. The OpCo Revolver Amendment, among other things, extended the maturity date of the OpCo Revolver from September 25, 2023 to July 12, 2027 and provided for the replacement of LIBOR with the Secured Overnight Financing Rate, as administered by the Federal Reserve Bank of New York ("SOFR"). Borrowings under the OpCo Revolver now bear interest at a variable rate of either (a) SOFR plus the Applicable Margin plus a 0.10 % credit spread adjustment or, if SOFR is no longer available, (b) the Alternate Base Rate plus the Applicable Margin minus 1.0 %. The Applicable Margin under the OpCo Revolver is 1.75 %. As of December 31, 2024, outstanding borrowings under the OpCo Revolver bore interest at SOFR plus the Applicable Margin and credit spread adjustment.
On April 29, 2015, the Partnership entered into a $300,000 revolving credit facility agreement with an affiliate of Westlake (as subsequently amended, the "MLP Revolver"). In 2017, the Partnership entered into an amendment to the MLP Revolver credit agreement, increasing borrowing capacity from $300,000 to $600,000 . On July 12, 2022, the Partnership entered into the Fourth Amendment (the "MLP Revolver Amendment") to the MLP Revolver. Prior to the MLP Revolver Amendment, the MLP Revolver bore interest at a variable rate of either (a) LIBOR plus 2.0 % or, if LIBOR were no longer available, (b) the Alternate Base Rate plus 1.0 %. The MLP Revolver Amendment, among other things, extended the maturity date of the MLP Revolver from March 19, 2023 to July 12, 2027 and provided for the replacement of LIBOR with SOFR as the reference rate. Borrowings under the MLP Revolver now bear interest at a variable rate of either (a) SOFR plus the Applicable Margin plus a 0.10 % credit spread adjustment or, if SOFR is no longer available, (b) the Alternate Base Rate plus the Applicable Margin minus 1.0 %. The Applicable Margin under the MLP Revolver varies between 1.75 % and 2.75 %, depending on the Partnership's Consolidated Leverage Ratio. As of December 31, 2024, outstanding borrowings under the MLP Revolver bore interest at SOFR plus the Applicable Margin and credit spread adjustment. The MLP Revolver provides that the Partnership may pay all or a portion of the interest on any borrowings in kind, in which case any such amounts would be added to the principal amount of the loan. The MLP Revolver requires that the Partnership maintain a consolidated leverage ratio of either (1) during any one-year period following certain types of acquisitions (including acquisitions of additional interests in OpCo), 5.50 :1.00 or less, or (2) during any other period, 4.50 :1.00 or less. The MLP Revolver also contains certain other customary covenants. The repayment of borrowings under the MLP Revolver is subject to acceleration upon the occurrence of an event of default.
As of December 31, 2024, the Partnership was in compliance with all of the covenants under the OpCo Revolver and the MLP Revolver.
The weighted average interest rate on all long-term debt was 6.4 % and 7.2 % at December 31, 2024 and 2023, respectively.
As of December 31, 2024, the Partnership had no scheduled maturities of long-term debt until 2027. The OpCo Revolver and the MLP Revolver are scheduled to mature on July 12, 2027.

9. Distributions and Net Income Per Limited Partner Unit
On January 27, 2025, the board of directors of Westlake Chemical Partners GP LLC ("Westlake GP"), the Partnership's general partner, declared a quarterly cash distribution for the period from October 1, 2024 to December 31, 2024 of $0.4714 per common unit. This distribution was paid on February 25, 2025 to unitholders of record as of February 7, 2025.
Distributions are declared subsequent to quarter end; therefore, the table below represents total cash distributions declared from earnings of the related periods pertaining to such distributions.

Distribution in excess of net income | $ | ( | $ | ( | $ | ( | |||||||||||||||||||||||
Net income per unit applicable to common limited partner units is computed by dividing the respective limited partners' interest in net income by the weighted-average number of common units outstanding for the period. Because the Partnership has more than one class of participating securities, it uses the two-class method when calculating the net income per unit applicable to limited partners. The classes of participating securities include common units and incentive distribution rights. Net income attributable to the Partnership is allocated to the unitholders in accordance with their respective ownership percentages in preparation of the consolidated statements of changes in equity. However, when distributions related to the incentive distribution rights are made, net income equal to the amount of those distributions is first allocated to the general partner before the remaining net income is allocated to the unitholders based on their respective ownership percentages. Basic and diluted net income per unit is the same because the Partnership does not have any potentially dilutive units outstanding for the periods presented.

The amended Partnership Agreement provides that the Partnership will distribute cash that is deemed to be an appropriate portion of the Partnership's total operating surplus. If cash distributions to the Partnership's unitholders exceed $1.2938 per common unit in any quarter, the Partnership's unitholders and Westlake, as the holder of the Partnership's incentive distribution rights, will receive distributions according to the following percentage allocations:

11. Related Party Transactions
Related party transactions between the Partnership, OpCo and Westlake are primarily based on agreements such as the Ethylene Sales Agreement, the Feedstock Supply Agreement, the Services and Secondment Agreement, Site Lease Agreements, the Omnibus Agreement, the Investment Management Agreement, the Exchange Agreement, the OpCo Partnership Agreement, the OpCo Revolver and the MLP Revolver. These agreements, discussed in detail in Notes 2 and 8, reflect the pervasive effect of the relationship with Westlake on the Partnership's operations and its consolidated financial statements. Pursuant to these agreements, the Partnership and OpCo regularly enter into transactions with Westlake. See below for descriptions and details of significant related party transactions.
Sales to Related Parties
OpCo sells ethylene to Westlake under the Ethylene Sales Agreement. Additionally, the Partnership and OpCo from time to time provide other services or products for which it charges Westlake a fee.
OpCo sells a significant portion of its ethylene production to Westlake. Sales to related parties were as follows:
| Year Ended December 31, | ||||||||||||||||||||
| 2024 | 2023 | 2022 | ||||||||||||||||||
| Net sales—Westlake | $ | $ | $ | |||||||||||||||||
As a result of the Partnership's decision to postpone the previously announced maintenance turnaround at the Petro 1 facility from the third quarter of 2024 to the first quarter of 2025, OpCo's production resulted in "excess quantities" of ethylene for the contract year ended December 31, 2024. Pursuant to the terms of the Ethylene Sales Agreement, the excess quantities produced by the Partnership during the year ended December 31, 2024 were sold to Westlake at prices that excluded certain non-variable costs of production.
Based on OpCo's 2022 production, the Partnership recognized buyer deficiency fees of $23,835 during the year ended December 31, 2022. The buyer deficiency fee is measured periodically based upon the lower of the actual production deficiency at period end or the estimated annual production deficiency based upon OpCo's annual anticipated production. These periodic estimates are updated at the end of the year based on actual annual production. The buyer deficiency fees are classified as a component of net sales—Westlake. The buyer deficiency fee was received by the Partnership in January 2023.
Cost of Sales from Related Parties
Charges for goods and services purchased by the Partnership and OpCo from Westlake and included in cost of sales relate primarily to feedstock purchased under the Feedstock Supply Agreement and services provided under the Services and Secondment Agreement.
A significant portion of the Partnership's inputs included in cost of sales are supplied by Westlake. Charges from related parties for significant inputs included in cost of sales were as follows:

12. Unit-based Compensation
The Westlake Chemical Partners LP Long-Term Incentive Plan (the "Plan") was adopted on July 15, 2014 and provides for grants of unit options, restricted units, phantom units, unit awards, distribution equivalent rights ("DERs") and other unit-based awards. The purpose of the Plan is to attract and retain the services of individuals who are essential for the growth and profitability of the Partnership and to encourage such individuals to devote their best efforts to advancing the business of the Partnership and its affiliates. Awards under the Plan are determined by the board of directors of the Partnership's general partner or a committee thereof (the "Committee"). Under the Plan, DERs may be granted, which represent a contingent right to receive an amount in cash, units, restricted units and/or phantom units, as determined by the Committee at its sole discretion, equal in value to the cash distributions made by the Partnership with respect to a common unit during the period such award is outstanding. The terms and conditions of each award are determined by the Committee. The maximum number of common units of the Partnership that may be delivered with respect to awards under the Plan is 1,270,000 . The phantom units along with a corresponding number of DERs were granted to certain non-employee directors of the general partner of the Partnership during the years ended December 31, 2024, 2023 and 2022. These phantom units vest on the first anniversary of the grant date. There were no forfeitures under the Plan during 2024, 2023 and 2022. The total fair value of phantom units that vested during the years ended December 31, 2024, 2023 and 2022 was $423 , $278 and $284 , respectively.
Non-vested phantom unit awards as of December 31, 2024 and 2023 and changes during the period were as follows:
| Number of Units | Weighted Average Fair Value | |||||||||||||
| Non-vested balance at December 31, 2023 | $ | |||||||||||||
| Granted | ||||||||||||||
| Vested | ( | |||||||||||||
| Non-vested balance at December 31, 2024 | $ | |||||||||||||
Each phantom unit represents the right to receive, upon vesting, either a cash payment equal to the fair market value of one Partnership common unit or a Partnership common unit. Each DER has distribution rights only so long as the phantom units to which it relates to has not vested or been settled.
The awards, which are classified as liability awards for financial accounting purposes, are measured at fair value on the grant date of the award and are re-measured at each reporting date until they vest based on the market price of the Partnership's units. The total units available for grant at December 31, 2024 were 1,192,349 . The total compensation cost recognized during the years ended December 31, 2024, 2023 and 2022 was $373 , $349 and $282 , respectively, and is included in selling, general and administrative expenses and the related liability is classified as accrued and other liabilities in the consolidated financial statements of the Partnership. The unrecognized compensation cost associated with all grants under the Plan at December 31, 2024 was $201 and the weighted average remaining term of the units at December 31, 2024 was 0.6 years.
13. Fair Value Measurements
The Partnership reports certain assets and liabilities at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). Under the accounting guidance for fair value measurements, inputs used to measure fair value are classified in one of three levels:
Level 1: Quoted market prices in active markets for identical assets or liabilities.
Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.
Level 3: Unobservable inputs that are not corroborated by market data.

WESTLAKE CHEMICAL PARTNERS LP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(in thousands of dollars, except unit amounts and per unit data)
The Partnership has financial assets and liabilities subject to fair value measures. These financial assets and liabilities include cash and cash equivalents, accounts receivable, net, accounts payable and long-term debt payable to Westlake, all of which are recorded at carrying value. The amounts reported in the consolidated balance sheets for cash and cash equivalents, accounts receivable, net and accounts payable approximate their fair value due to the short maturities of these instruments. The carrying and fair values of the Partnership's long-term debt at December 31, 2024 and December 31, 2023 are summarized in the table below. The fair value of long-term debt is determined based on the present value of expected future cash flows using a discounted cash flow methodology. Because the Partnership's valuation methodology used for long-term debt requires the use of significant unobservable inputs, the inputs used to measure the fair value of the Partnership's long-term debt are classified as Level 3 within the fair value hierarchy. Inputs used to estimate the fair values of the Partnership's long-term debt include the selection of an appropriate discount rate.

14. Income Taxes
The Partnership is a limited partnership and is treated as a partnership for U.S. federal income tax purposes and, therefore, is not liable for entity-level federal income taxes. The Partnership is, however, subject to state and local income taxes.

All insurance recovery proceeds were collected as of December 31, 2024. These recoveries were related to the settlement of insurance claims for Hurricane Laura, which impacted OpCo's Petro 1 and Petro 2 units in the second half of 2020 and impacted production in the subsequent periods.
Cash Flow Information
Non-cash Investing Activity
Capital expenditure related liabilities, included in accounts payable—third parties and accrued and other liabilities, were $9,863 , $7,809 , and $6,372 at December 31, 2024, 2023, and 2022, respectively.
Interest and Income Taxes
Interest paid by the Partnership, net of interest capitalized, was $26,528 , $24,537 and $10,850 for the years ended December 31, 2024, 2023 and 2022, respectively.

Operating Leases
Right-of-use assets obtained in exchange for operating lease obligations were $758 , $5,079 and $0 for the years ended December 31, 2024, 2023 and 2022, respectively.
16. Commitments and Contingencies
The Partnership is subject to environmental laws and regulations that can impose civil and criminal sanctions and that may require the Partnership to mitigate the effects of contamination caused by the release or disposal of hazardous substances into the environment. These laws include the federal Clean Air Act, the federal Water Pollution Control Act, the Resource Conservation and Recovery Act, the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"), the Toxic Substances Control Act and various other federal, state and local laws and regulations. Under CERCLA, an owner or operator of property may be held strictly liable for remediating contamination without regard to whether that person caused the contamination, and without regard to whether the practices that resulted in the contamination were legal at the time they occurred. Because the Partnership's production sites have a history of industrial use, it is impossible to predict precisely what effect these legal requirements will have on the Partnership. Pursuant to the Omnibus Agreement, certain subsidiaries of Westlake will indemnify the Partnership for liabilities that occurred or existed prior to August 4, 2014.
The Partnership is also involved in other legal proceedings incidental to the conduct of its business. After considering all relevant facts and circumstances, including applicable insurance and indemnification by Westlake, the Partnership does not believe that any of these legal proceedings will have a material adverse effect on its financial condition, results of operations or cash flows.
Other Commitments
The Partnership has various purchase commitments for its capital projects and for materials, supplies and services incident to the ordinary conduct of business.

17. Segment Information
The Partnership has one operating segment, which is the Partnership's reportable segment, OpCo. The operating results of the segment are reviewed by the Partnership's Chief Executive Officer, the chief operating decision maker ("CODM"). The CODM evaluates segment performance based on net income. The CODM reviews the OpCo segment's actual net income trends to allocate resources and assess performance.
The OpCo segment's operations consist of two ethylene production facilities in Lake Charles, Louisiana, one ethylene production facility in Calvert City, Kentucky and a 200-mile common carrier ethylene pipeline that runs from Mont Belvieu, Texas to Longview, Texas. OpCo derives substantially all of its revenue from these production facilities primarily by selling ethylene to Westlake and others, as well as through the sale of co-products of ethylene production, including propylene, crude butadiene, pyrolysis gasoline and hydrogen. All of the OpCo segment's operations are located and conducted in the United States. All of the OpCo segment's sales are attributed to the United States.
Sales to Westlake accounted for more than 10% of sales in the OpCo segment, totaling $950,801 , $1,026,655 and $1,342,910 for the years ended December 31, 2024, 2023 and 2022, respectively. Consolidated net sales and provision for income taxes as disclosed in the consolidated statements of operations and depreciation and amortization and additions to property, plant and equipment as disclosed in the consolidated statements of cash flows are fully attributed to the OpCo segment, and as such, separate OpCo segment amounts are not repeated in the tables below.
The accounting policies of the OpCo segment are the same as those described in Note 1.

PART III
Item 10. Directors, Executive Officers and Corporate Governance
We are managed and operated by the board of directors and executive officers of our general partner, Westlake Chemical Partners GP LLC, a wholly-owned subsidiary of Westlake. As a result of owning our general partner, Westlake has the right to appoint all members of the board of directors of our general partner (the "board" or the "board of directors"), including at least three directors meeting the independence standards established by the NYSE and the Exchange Act. Our unitholders are not entitled to elect our general partner or its directors or otherwise directly participate in our management or operations. Our general partner owes certain contractual duties to our unitholders as well as a fiduciary duty to its owner, Westlake.
Our general partner has eight directors, three of whom are independent as defined under the standards established by the NYSE and the Exchange Act. The NYSE does not require a listed, publicly-traded partnership, such as ours, to have a majority of independent directors on the board of directors or to establish a compensation committee or a nominating committee. However, our general partner is required to have an audit committee of at least three members, and all its members are required to meet the independence and experience standards established by the NYSE and the Exchange Act.
All of the executive officers of our general partner listed below allocate their time between managing our business and affairs and the business and affairs of Westlake. The amount of time that our executive officers devote to our business and the business of Westlake varies in any given period based on a variety of factors. We expect our general partner's executive officers to devote as much time as is necessary for the proper conduct of our business and affairs. However, their fiduciary duties to Westlake and other obligations may prevent them from devoting sufficient time to our business and affairs.
We reimburse our general partner and its affiliates, including Westlake, for all expenses they incur and payments they make on our behalf. The Partnership Agreement does not set a limit on the amount of expenses for which our general partner and its affiliates may be reimbursed. For the year ended December 31, 2024, we paid approximately $197.6 million for such expenses. These expenses include those we and OpCo incur under the Services and Secondment Agreement and the Omnibus Agreement, including salary, bonus, incentive compensation and other amounts paid to persons who perform services for us or on our behalf and expenses allocated to our general partner by Westlake.
In evaluating director candidates for our general partner, Westlake will assess whether a candidate possesses the integrity, judgment, knowledge, experience, skill and expertise that are likely to enhance the board's ability to manage and direct our affairs and business, including, when applicable, to enhance the ability of committees of the board to fulfill their duties.
Executive Officers and Directors of Our General Partner
The following table shows information for the executive officers and directors of our general partner as of February 28, 2025. Directors hold office until their successors have been elected or qualified or until the earlier of their death, resignation, removal or disqualification. Executive officers serve at the discretion of the board. The Executive Chairman of the Board of Directors and the Senior Chairman of the Board of Directors are brothers. Otherwise, there are no familial relationships among any of our general partner's directors or executive officers. Some of the directors and most of the executive officers of our general partner also serve as executive officers of Westlake. The directors and executive officers of our general partner have a fiduciary duty to manage our general partner in a manner beneficial to Westlake. Please read "Item 1A. Risk Factors—Risks Relating to Our Partnership Structure." Each director and executive officer of our general partner will be fully indemnified by us for actions associated with being a director or executive officer to the fullest extent permitted under Delaware law pursuant to the Partnership Agreement.

Director Independence
In accordance with the rules of the NYSE, the board of directors of our general partner currently has three independent directors. The board of directors of our general partner has determined that each of Messrs. Finley and Woelfel and Ms. Friel is independent as defined under the independence standards established by the NYSE and the Exchange Act.
Committees of the Board of Directors of our General Partner
The board of directors of our general partner has one standing committee: the audit committee. The board of directors of our general partner may also form a conflicts committee from time to time.
Audit Committee
The audit committee of our general partner's board of directors (the "audit committee") has been established in accordance with Section 3(a)(58)(A) of the Exchange Act, and consists of Messrs. Finley and Woelfel and Ms. Friel, all of whom are independent. Mr. Finley is the current chairman of the audit committee. The board of directors of our general partner has determined that each of Messrs. Finley and Woelfel and Ms. Friel is an "audit committee financial expert" within the meaning of the SEC rules and "financially literate" within the meaning of the NYSE regulations. The audit committee operates pursuant to a written charter, an electronic copy of which is available on our website at www.wlkpartners.com.
The audit committee assists the board of directors of our general partner in its oversight of the integrity of our consolidated and combined financial statements and our compliance with legal and regulatory requirements and partnership policies and controls. The audit committee has the sole authority to (1) retain and terminate our independent registered public accounting firm, (2) approve all auditing services and related fees and the terms thereof performed by our independent registered public accounting firm, and (3) pre-approve any non-audit services and tax services to be rendered by our independent registered public accounting firm. The audit committee is also responsible for confirming the independence and objectivity of our independent registered public accounting firm. Our independent registered public accounting firm is given unrestricted access to the audit committee and our management, as necessary.
79
Conflicts Committee
As set forth in the limited liability company agreement of our general partner, our general partner's board of directors may, from time to time, form a conflicts committee to which the board of directors of our general partner will appoint independent directors and which may be asked to review specific matters that the board believes may involve conflicts of interest between us, our limited partners and Westlake. The conflicts committee will determine the resolution of the conflict of interest in any manner referred to it in good faith. The members of the conflicts committee may not be officers or employees of our general partner or directors, officers or employees of its affiliates, including Westlake, and must meet the independence standards established by the NYSE and the Exchange Act to serve on an audit committee of a board of directors, along with other requirements in the Partnership Agreement. Messrs. Finley and Woelfel and Ms. Friel serve on the conflicts committee. Mr. Woelfel is the current chair of the conflicts committee. Any matters approved by the conflicts committee in good faith will be conclusively deemed to be fair and reasonable to us, approved by all of our partners and not a breach by our general partner of any duties it may owe us or our unitholders.
Meetings of the Board
During the last fiscal year, our general partner's board of directors held ten meetings and our general partner's audit committee held seven meetings. Our general partner's conflicts committee did not hold any meetings in the last fiscal year. None of the directors attended fewer than 75% of the aggregate number of meetings of the board of directors and committees of the board on which the director served.
The board of directors holds regular executive sessions in which the independent directors meet without any non-independent directors or members of management. The purpose of these executive sessions is to promote open and candid discussion among the independent directors. The rules of the NYSE require that one of the independent directors must preside over each executive session, and the role of presiding director is rotated among each of the independent directors.
Communication with the Board of Directors
A holder of our units or other interested party who wishes to communicate with the non-management directors may do so by contacting our corporate secretary at the address or phone number appearing on the front page of this report. Communications will be relayed to the intended recipient of the board of directors except in instances where it is deemed unnecessary or inappropriate to do so pursuant to the procedures established by the audit committee. Any communications withheld under those guidelines will nonetheless be recorded and available for any director who wishes to review them.
Corporate Governance Guideline and Code of Ethics
We have adopted a Code of Ethics for the Principal Executive Officer, Principal Financial Officer and Principal Accounting Officer (the "Code of Ethics") that applies to each of the Principal Executive, Financial and Accounting Officers of our general partner, as required by Section 406 of the Sarbanes-Oxley Act of 2002. Furthermore, we have adopted Principles of Corporate Governance and a charter for our audit committee. Each of the foregoing is available on our website at www.wlkpartners.com in the "Corporate Governance" section of our Investor Relations tab. We provide copies, free of charge, of any of the foregoing upon receipt of a written request. We disclose amendments and director and executive officer waivers with regard to the Code of Ethics, if any, on our website or by filing a Current Report on Form 8-K to the extent required. Furthermore, the certifications of our general partner's Chief Executive Officer and Chief Financial Officer, as required by Section 302 of the Sarbanes-Oxley Act, have been included as exhibits to this report.
NYSE Corporate Governance Listing Standards
The NYSE requires the chief executive officer of each listed company to certify annually that he is not aware of any violation by the company of the NYSE corporate governance listing standards as of the date of the certification, qualifying the certification to the extent necessary. The Chief Executive Officer of our general partner provided such certification to the NYSE in 2024 without qualification. You can also find information about us at the offices of the NYSE, 20 Broad Street, New York, New York 10005 or at the NYSE's Internet site (www.nyse.com).

Item 11. Executive Compensation
Compensation Discussion and Analysis
Overview
Neither we nor our general partner directly employ any of the persons responsible for managing our business. All of our general partner's executive officers are employees of Westlake. In accordance with the terms of the Omnibus Agreement with Westlake, effective August 4, 2014, as amended, we reimburse Westlake for compensation-related expenses attributable to the portion of our executive officers' time dedicated to providing services to us. In connection with Westlake's annual budget process, Westlake determines a budgeted allocation rate, which represents an estimated average percentage of expected time that will be spent by each of the executive officers on our business during the succeeding year. The executive officers provide input as to what those estimated percentages should be. Those estimates are revised each year based on historical experience and business plans for the following year. The executive officers do not keep logs of their time spent on our matters. Since the allocation rate is initially estimated, the actual time spent by an executive officer on our behalf may vary from the budgeted allocation rate, and we may recognize an adjustment at the end of the year if allocating more or less of that executive officer's compensation than the actual percentage of his time spent on our behalf in a given year. During 2024, Mr. Albert Chao, who served as President and Chief Executive Officer until July 2024, devoted approximately 5% of his total business time to our general partner, our consolidated subsidiaries (including OpCo) and us and Jean-Marc Gilson, who was appointed President and Chief Executive Officer in July 2024, devoted approximately 5% of his total business time to our general partner, our consolidated subsidiaries (including OpCo) and us. Mr. Steven Bender devoted approximately 10% of his total business time to our general partner, our consolidated subsidiaries (including OpCo) and us. The allocation of the executive officers' time in future years and, in turn, future compensation allocations may differ from the time and compensation allocated for each executive officer in 2024.
Westlake has determined that only the base salary of each of the Westlake executive officers shall be allocated to us based on the percentages of business time set forth above. This is because Westlake's other compensation components such as Westlake equity awards and annual and quarterly cash incentive plans are determined based on the achievement of specific performance goals of Westlake's business, and not our business. Westlake has significant assets and holdings outside of us and our general partner.
Named Executive Officers
For 2024, our named executive officers ("NEOs") consisted of our general partner's principal executive officers, Mr. Albert Chao (in such position until July 15, 2024) and Mr. Jean-Marc Gilson (appointed to such position on July 15, 2024), and our general partner's principal financial officer, Mr. Steven Bender. The compensation allocated to us in 2024 for each of the other executive officers of our general partner did not exceed $100,000. Therefore, none of the other executive officers are considered NEOs for 2024.
Compensation Decisions
Westlake has ultimate decision-making authority with respect to the total compensation of our NEOs because our NEOs are employed by Westlake. Any such compensation decisions will not be subject to any approvals by us, the board of directors or any committees thereof.
Except for amounts that we pay to Westlake under the Omnibus Agreement, we do not otherwise pay or reimburse any compensation amounts to or for our NEOs. Each of our executive officers (including our NEOs) is eligible to receive grants of unit-based awards under the Westlake Chemical Partners LP Long Term Incentive Plan (as amended and restated effective May 8, 2024) (the "LTIP"), but none has to date received any awards (including options or similar equity awards) under the LTIP. As a result, we have not adopted a policy regarding the timing of grants of option awards. Any awards under the LTIP must be approved by the board of directors.
Westlake Compensation Committee Oversight
The board of directors of Westlake has established a compensation committee (the "Westlake Compensation Committee") to review and provide oversight of the compensation programs of Westlake and the compensation of the principal executive officer of Westlake (the "Westlake PEO"), the other named executive officers of Westlake (together with the Westlake PEO, the "Westlake NEOs") and other employees designated as executive officers of Westlake (collectively, the "Westlake Executives").
81
External Advisors
To assist the Westlake Compensation Committee in respect of its oversight responsibilities, the Westlake Compensation Committee periodically utilizes the services of independent third-party compensation consultants to conduct compensation surveys and determine compensation trends, analyze and assess Westlake's compensation systems and programs (which includes the compensation of the Westlake Executives), review current legal, accounting and administrative matters associated with executive compensation and offer opinions as to the effectiveness and competitiveness of the program. For 2024, the Westlake Compensation Committee directly engaged the services of Willis Towers Watson as a compensation consultant to advise the Westlake Compensation Committee on executive compensation matters. Willis Towers Watson assists the Westlake Compensation Committee by providing comparative market data on compensation programs and practices of peer competitors, the broader-based chemical and building products industries and general industry. Willis Towers Watson also assists Westlake with general compensation consultation regarding employees other than the Westlake NEOs. In 2024, Westlake paid Willis Towers Watson approximately $162,000 for compensation advisory services and approximately $2.1 million for other services (primarily related to the administration of Westlake's legacy defined benefit retirement plans). The decision to engage Willis Towers Watson for the non-executive-compensation services of Westlake was made by Westlake management and approved by the Westlake Compensation Committee. In February 2025, the Westlake Compensation Committee assessed whether the work of Willis Towers Watson for Westlake during 2024 raised any conflict of interest and concluded that no conflict of interest exists.
The Deliberative Process
In establishing targeted levels of executive compensation, the Westlake Compensation Committee has selected a set of peer group companies (the "Peer Group") from among companies of relative comparable size to Westlake, with executive positions of similar scope and responsibility, and from among companies with which Westlake may compete for executive talent. With the assistance of Willis Towers Watson, the Westlake Compensation Committee reviews the Peer Group on a regular basis. To validate current peers and identify potential new peer companies, Willis Towers Watson conducts a comprehensive review using both objective and qualitative criteria that the Westlake Compensation Committee deems to be appropriate, including recent developments with current peer companies (e.g., merger and acquisition activity and changes in financial performance), revenue, industry classification, market capitalization and other financial data, peers of peers analysis, business and product portfolios, peers as identified by proxy advisory firms such as ISS and Glass Lewis, and business and labor market competitors, with an overall objective of achieving approximately a median ranking for Westlake within the Peer Group.
The following companies from both the chemicals and building products industries made up the Peer Group as adopted by the Westlake Compensation Committee for purposes of determining compensation for the Westlake NEOs for 2024:
| Builders FirstSource, Inc. | LyondellBasell Industries N.V. | |||||||
| Celanese Corporation | Masco Corporation | |||||||
The Chemours Company | The Mosaic Company | |||||||
Dow Inc. | Olin Corporation | |||||||
| DuPont de Nemours, Inc. | Owens Corning | |||||||
| Eastman Chemical Company | PPG Industries, Inc. | |||||||
Ecolab Inc. | RPM International Inc. | |||||||
Huntsman Corporation | The Sherwin-Williams Company | |||||||
As disclosed in Westlake's 2024 Proxy Statement, in November 2023, as part of its annual evaluation process, and upon recommendation by Willis Towers Watson, the Westlake Compensation Committee determined, and the Westlake board of directors agreed, the 2024 selected Peer Group would be updated to achieve an approximately median ranking for Westlake relative to the peer group. Going forward, the Westlake Compensation Committee will continue to evaluate and make changes in the Peer Group as warranted to reflect changes in the size, business profile and publicly-listed status of the companies to help ensure that companies comparable in size and business profile to Westlake are included and continue to be appropriate for the compensation decision-making process.
82
In addition to referring to the Peer Group, Willis Towers Watson utilizes survey data from its proprietary compensation databases, including, but not limited to, the Willis Towers Watson CDB Executive Survey and other relevant market information. These surveys compare the compensation of executives at numerous companies to similar positions as the Westlake NEOs (the "Market Survey"). The Market Survey is used in conjunction with the Peer Group data (collectively, the "Reference Points") to help validate the market findings and more specifically establish market compensation rates for positions with limited Peer Group data and/or for positions that are not industry-specific and for which Westlake would need to recruit on a broader basis (for instance, Chief Financial Officer). Finally, in establishing the target executive compensation, the Westlake Compensation Committee takes a total compensation view to include base pay, cash bonuses and long-term incentives, so that as long as the composite total compensation of a Westlake NEO is competitive with the Reference Points, individual components may fall below or above the median of the Reference Points. In conducting its surveys for the Reference Points, Willis Towers Watson reports directly to the Westlake Compensation Committee on each component and on a composite total compensation basis.
The Westlake Compensation Committee meets annually in February to address the compensation of the Westlake NEOs and other Westlake Executives, including each of our NEOs. During this meeting, the Westlake Compensation Committee reviews the achievement of Westlake's goals and objectives, including Westlake's Economic Value Added (defined as the net operating profit after taxes in relation to capital employed) and performance relative to its competitors within the chemical and building products industries, including those direct competitors within the Peer Group, the Reference Points and other relevant factors established by the Westlake Compensation Committee. During this deliberation, the Westlake PEO is excused from the meeting to allow the members of the Westlake Compensation Committee to deliberate independently regarding the Westlake PEO's compensation. During this annual review meeting, the Westlake PEO also presents his recommendations to the Westlake Compensation Committee regarding the compensation to be provided to the other Westlake NEOs and other Westlake Executives. The Westlake PEO and the Westlake Compensation Committee, after considering data from the Reference Points and other relevant factors, set the compensation for these Westlake Executives.
Compensation Philosophy and Program Objectives of Westlake
Westlake has designed and maintains a comprehensive executive compensation program as a means of:
•attracting, rewarding and retaining top executive talent in support of Westlake's vision, mission and objectives;
•maintaining market competitiveness with Westlake's peer group compensation programs and practices;
•encouraging and rewarding the achievement of specific individual, business segment and corporate goals and objectives;
•placing a significant portion of total compensation at risk through variable pay components, including upside potential where targeted objectives are exceeded, to promote management action to create added stockholder value;
•aligning management interests with the interests of Westlake's stockholders; and
•balancing short-term objectives with long-term strategic initiatives.
Establishing Compensation Levels
On an annual basis as the Westlake Compensation Committee meets to set the target compensation for the Westlake PEO, other Westlake NEOs and other Westlake Executives, the Westlake Compensation Committee considers the responsibility and scope of the individual job assignments as well as the Westlake Executive's job performance and achievements measured against a variety of goals and objectives. As a first step, the Westlake PEO provides his evaluation of each Westlake Executive based upon the achievement of goals and objectives unique to a business segment or a corporate assignment and an assessment of the Westlake Executive's individual contribution and effort and a variety of managerial success factors. Next, the Westlake Compensation Committee may make its own assessment of each Westlake Executive based upon the interaction Westlake Compensation Committee members have had with the Westlake Executive throughout the year. Lastly, once the Westlake Compensation Committee considers all of these factors in tandem with the Reference Points, the Westlake Compensation Committee establishes the compensation target for each element of the total compensation program.
83
Base Pay—This element is the principal cash compensation component of Westlake's program and is designed to provide the Westlake Executive with a market-competitive minimum level of compensation. In setting base pay rates for 2024, the Westlake Compensation Committee considered the Reference Points, the scope and range of responsibility, accountability and business impact of the position as well as current economic conditions to aid it in evaluating and matching the positions with the market and setting fair-market competitive base pay targets. In setting base pay rates for Westlake Executives, the Westlake Compensation Committee has determined that, based on advice of its independent consultant, Willis Towers Watson, the base pay of the Westlake Executives can generally be considered as competitive if targeted to be within 90% to 110% of the 50th percentile of the market depending on the performance of the individual Westlake Executive, the magnitude of adjustments deemed necessary by the Westlake Compensation Committee to ensure retention of the Westlake Executive and the performance of Westlake. The Westlake Compensation Committee also recognizes that market pricing is an inexact science and that base pay above or below that range may be required to meet market demand or to recognize individual performance or experience levels. The Westlake Compensation Committee does not set a specific fixed target percentage for any of the Westlake NEOs but generally works to set the base pay of each Westlake NEO to be within the range at its discretion based upon market and performance factors. Base pay is evaluated on an annual basis using then current market information, and the Westlake Compensation Committee may authorize an adjustment to:
•ensure that the Westlake Executive's current base pay is within the acceptable target level as determined by the Westlake Compensation Committee;
•ensure internal equity;
•recognize individual performance and contributions; or
•recognize changes in responsibility or the scope of the Westlake Executive's position.
For additional information regarding compensation decisions made by the Westlake Compensation Committee during 2024, including Westlake's equity awards and annual and quarterly cash incentive plans, see the proxy statement that is expected to be filed by Westlake in connection with its 2025 annual meeting of stockholders. In February 2025, the Westlake Compensation Committee elected to increase the base salary for Mr. Gilson to $1,300,000 from $1,250,000 and for Mr. Bender to $785,000 from $755,000.
Employment Agreements; Termination or Change-in-Control Arrangements
Employment Agreements—Westlake does not have employment agreements with any of the Westlake NEOs; however, each Westlake Executive, including each of the Westlake NEOs, is typically provided an offer letter of employment containing the principal elements of the employment arrangement, including compensation.
Termination or Change-in-Control Arrangements—Although none of the offer letters contain a provision for payments by us upon termination or a change in control, in 2023, following shareholder approval, Westlake incorporated change in control provisions into its annual cash incentive plan and long-term equity incentive plan that provide for certain benefits on a qualifying termination of employment within a twenty-four-month period following a change in control of Westlake for awards that are assumed or replaced with equivalent awards or protections in connection with a change in control of Westlake if such awards were not assumed or replaced with equivalent awards. Furthermore, award agreements under Westlake's long-term equity incentive plan contain provisions that provide for certain accelerated vesting benefits in the event of termination by reason of death, normal retirement or, in certain circumstances, without cause, and Westlake's annual cash incentive plan provides for the payment of a prorated bonus and certain banked amounts in the event of termination by reason of death, permanent disability, normal retirement or an approved reduction-in-force. For additional information on termination and change in control provisions, see the section titled "2024 Potential Payments Upon Termination or Change in Control" of the proxy statement that is expected to be filed by Westlake in connection with its 2025 annual meeting of stockholders. We are not required to reimburse Westlake for any portion of such benefits that may become payable to our NEOs either in connection with or following a termination of employment or a change in control of Westlake.
84
Recovery of Erroneously Awarded Compensation
In November 2023, the board of directors approved a policy for recovering erroneously awarded compensation, or "clawback" policy, applicable to executive officers. The policy implements the incentive-based compensation recovery provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 as required under the listing standards of the New York Stock Exchange, and requires recovery of incentive-based compensation received by current or former executive officers during the three fiscal years preceding the date it is determined that the Partnership is required to prepare an accounting restatement, including to correct an error that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. The amount required to be recovered is the excess of the amount of incentive-based compensation received over the amount that otherwise would have been received had it been determined based on the restated financial measure. As of the date hereof, none of our current or former executive officers have received incentive-based compensation from us for their services.

Director Compensation
Officers or employees of Westlake or its affiliates who also serve as directors do not receive additional compensation for such service.

All phantom unit awards vest on the first anniversary of their grant date. Mr. Finley, the audit committee chairman, received an additional cash retainer of $20,000.
In addition, each non-employee director is reimbursed for out-of-pocket expenses in connection with attending board and committee meetings. Each director is fully indemnified by us for actions associated with being a director to the fullest extent permitted under Delaware law pursuant to the Partnership Agreement.

(1)The amounts reflected in this column represent the grant date fair value of phantom unit awards granted to the non-employee directors, computed in accordance with FASB ASC Topic 718, as the product of (i) the number of phantom units granted and (ii) the average of the high and low prices of our common units reported on the New York Stock Exchange on the grant date. For a discussion of the related valuation assumptions, please see Note 12 to our consolidated financial statements included in this report. As of December 31, 2024, Ms. Friel and Messrs. Finley and Woelfel each held 4,882 phantom units, which will become fully vested on August 7, 2025.
(2)The amounts reflected in this column represent the amount of cash paid with respect to distribution equivalent rights granted in tandem with the phantom unit awards.
CEO Pay Ratio Analysis
The table below sets forth comparative information regarding: (1) the annualized total compensation of our Chief Executive Officer, Mr. Gilson, who has served as President and Chief Executive Officer since July 15, 2024, for the year ended December 31, 2024, determined on the basis set forth below; (2) the median of the annual total compensation of all seconded employees of Westlake that provide services to OpCo under the Services and Secondment Agreement, which excludes our Chief Executive Officer, for the year ended December 31, 2024, determined on the basis described below; and (3) a ratio comparison of those two amounts. These amounts were determined in accordance with rules prescribed by the SEC.
Neither we nor OpCo have any employees. However, for purposes of this disclosure, we have included the employees of Westlake and its other affiliates who are seconded to OpCo under the Services and Secondment Agreement for the production of ethylene (the "Seconded Employees"). For purposes of determining the median of the annual total compensation of our Seconded Employee population, excluding our Chief Executive Officer, for the year ended December 31, 2024, the applicable SEC rules require us to identify the median Seconded Employee by using either annual total compensation for all such employees or another consistently applied compensation measure. For these purposes, we used total taxable earnings, plus certain non-taxable items, including retirement plan contributions and perquisites, as determined from the payroll records of Westlake and its affiliates providing the services of the Seconded Employees to OpCo for the period from January 1, 2024 through December 31, 2024 (the "Measurement Date"), as our consistently applied compensation measure. We included all Seconded Employees of Westlake who provided services to OpCo as of the Measurement Date whether employed on a full-time, part-time or seasonal basis. We did not use statistical sampling or include any cost-of-living adjustments for purposes of this determination. After identifying the median Seconded Employee as of the Measurement Date, based on the process described above, we calculated 2024 total compensation for the median Seconded Employee and our Chief Executive Officer using the same methodology we used for determining total compensation for 2024 for our NEOs as set forth in the Summary Compensation Table. Since Mr. Gilson was not our Chief Executive Officer for all of 2024, to determine the Chief Executive Officer's annual total compensation, we included in the table below his base salary as reported in the Summary Compensation Table, annualized as if he had served for the entire year and multiplied by an annualized allocation percentage of 10%.
| Chief Executive Officer annual total compensation (A) | $ | 113,546 | ||||||
| Median annual total compensation of all employees (excluding Chief Executive Officer) (B) | $ | 169,913 | ||||||
| Ratio of (A) to (B) | 0.67 | |||||||

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters
The following table sets forth, as of February 21, 2025, the beneficial ownership of our outstanding common units and subordinated units held by:
•our general partner;
•Westlake;
•each director and named executive officer of our general partner; and
•all of the directors and executive officers of our general partner as a group.
We report the amounts and percentage of units beneficially owned on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. The rules of the SEC deem a person a "beneficial owner" of a security if that person has or shares "voting power" that includes the power to vote or to direct the voting of the security, or "investment power" that includes the power to dispose of or to direct the disposition of the security. In computing the number of common units beneficially owned by a person and the percentage ownership of that person, common units subject to options or warrants held by that person that are currently exercisable or exercisable within 60 days of February 21, 2025, if any, are deemed outstanding, but are not deemed outstanding for computing the percentage ownership of any other person. Unless otherwise noted, the address for each beneficial owner listed below is 2801 Post Oak Boulevard, Suite 600, Houston, Texas 77056. None of the units beneficially owned as set forth below is pledged as security.

Item 13. Certain Relationships and Related Transactions, and Director Independence
Westlake owns 14,122,230 common units, representing an aggregate approximate 40.1% limited partner interest in us; a 100% interest in our general partner; and our incentive distribution rights. Transactions with Westlake and its affiliated entities are considered to be related party transactions because Westlake and its affiliates own more than 5% of our equity interests; in addition, certain of Westlake's directors and executive officers also serve as directors and executive officers of our general partner.
Whenever a conflict arises between our general partner or its owners, on the one hand, and us or our limited partners, on the other hand, the resolution, course of action or transaction in respect of such conflict of interest shall be conclusively deemed approved by us and all our limited partners and shall not constitute a breach of the Partnership Agreement, of any agreement contemplated thereby or of any duty, if the resolution, course of action or transaction in respect of such conflict of interest is:
•approved by the conflicts committee of our general partner; or
•approved by the holders of a majority of our outstanding common units, excluding any such units owned by our general partner or any of its affiliates.
Our general partner may, but is not required to, seek the approval of such resolutions or courses of action from the conflicts committee of its board of directors or from the holders of a majority of the outstanding common units as described above. If our general partner does not seek approval from the conflicts committee or from holders of common units as described above and the board of directors approves the resolution or course of action taken with respect to the conflict of interest, then it will be presumed that, in making its decision, the board of directors acted "in good faith," and in any proceeding brought by or on behalf of us or any of our unitholders, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption and proving that such decision was not in good faith. Unless the resolution of a conflict is specifically provided for in the Partnership Agreement, the board of directors or its conflicts committee, as applicable, may consider any factors it determines in good faith to consider when resolving a conflict. An independent third party is not required to evaluate the resolution. Under the Partnership Agreement, all determinations, other actions or failures to act by our general partner, the board of directors or any committee thereof (including the conflicts committee) will be presumed to be "in good faith," and in any proceeding brought by or on behalf of us or any of our unitholders, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption and proving that such determination was not in good faith.
The information required by Item 407(a) of Regulation S-K is included in "Item 10. Directors, Executive Officers and Corporate Governance."
Procedures for Review, Approval and Ratification of Transactions with Related Persons
If a conflict or potential conflict of interest arises between our general partner or its affiliates, on the one hand, and us or our unitholders, on the other hand, the resolution of any such conflict or potential conflict should be addressed by the board of directors in accordance with the provisions of the Partnership Agreement. At the discretion of the board in light of the circumstances, the resolution may be determined by the board in its entirety or by a conflicts committee meeting the definitional requirements for such a committee under the Partnership Agreement.
Distributions and Payments to our General Partner and its Affiliates
We will generally make cash distributions to our unitholders, including Westlake, pro rata. In addition, if distributions exceed the minimum quarterly distribution and other higher target distribution levels, Westlake, as the holder of our incentive distribution rights, will be entitled to increasing percentages of the distributions, up to 50% of the distributions above the highest target distribution level.
Assuming we have sufficient available cash to pay the full minimum quarterly distribution of $0.2750 per unit on all of our outstanding units for four quarters, Westlake would receive an aggregate annual distribution of approximately $15.5 million on its common units. During 2024, we made aggregate distributions of $1.8856 per unit to all of our unitholders, resulting in Westlake receiving approximately $26.6 million.
Our general partner and its affiliates are entitled to reimbursement for all expenses they incur on our behalf, including salaries and employee benefit costs for employees who provide services to us, and all other necessary or appropriate expenses allocable to us or reasonably incurred by our general partner and its affiliates in connection with operating our business. Except to the extent specified in the Omnibus Agreement or the Services and Secondment Agreement, our general partner will determine the expenses that are allocable to us in good faith, but there is no limit on the amount of expenses for which our general partner and its affiliates will be reimbursed. For the year ended December 31, 2024, we paid approximately $197.6 million for such expenses.
91
If our general partner withdraws or is removed, its incentive distribution rights will either be sold to the new general partner for cash or converted into common units, in each case for an amount equal to the fair market value of those interests.
If we are ever liquidated, the partners, including Westlake, will be entitled to receive liquidating distributions according to their respective capital account balances.
Agreements with Westlake
Except as otherwise indicated, the agreements described below became effective on August 4, 2014, concurrent with the closing of the IPO. For amounts paid by us or Westlake, as applicable, under the agreements described below, see Note 11 to our consolidated financial statements.
Ethylene Sales Agreement
OpCo and Westlake are parties to the Ethylene Sales Agreement, which has an initial term through December 31, 2026 and automatic 12-month renewal periods until terminated at the end of the initial term or any renewal term on 12-months' notice. The Ethylene Sales Agreement requires Westlake to purchase OpCo's planned ethylene production each year, subject to certain exceptions and a maximum commitment of 3.8 billion pounds per year, less product sold by OpCo to third parties equal to approximately 5% of the annual output. Westlake's purchase price for its minimum commitment of ethylene under the Ethylene Sales Agreement includes a $0.10 per pound margin, the total costs incurred by OpCo for the feedstock and natural gas to produce each pound of ethylene (subject to a usage cap and a floor), and estimated operating costs, maintenance capital expenditures and other turnaround expenditures, less net proceeds from co-products sales. This purchase price is not designed to cover capital expenditures for expansion. Under specified circumstances, unrecovered costs may be carried forward for recovery in subsequent years. Variable costs not incurred by OpCo due to deficiencies in purchases by Westlake are rebated to Westlake. If OpCo's actual production is in excess of planned ethylene production, Westlake has the option to purchase up to 95% of production in excess of planned production. The price for the sale of such excess ethylene to Westlake is based on a formula similar to that used for the minimum purchase commitment, with the exception of certain fixed costs.
Certain of the pricing components that make up the price for ethylene sold under the Ethylene Sales Agreement are modified to reflect the portion of OpCo's production capacity that is used to process Westlake's purge gas instead of producing ethylene. Costs specific to the processing of Westlake's purge gas are recovered under the Services and Secondment Agreement, and not the Ethylene Sales Agreement.
On November 1, 2018, OpCo and Westlake entered into an amendment to the Ethylene Sales Agreement that provides OpCo with the option to curtail up to 5% of its ethylene production annually in the event OpCo reasonably determines that its sales of such ethylene to third parties during the relevant period would be uneconomic.
Feedstock Supply Agreement
OpCo and Westlake are parties to the Feedstock Supply Agreement, which has an initial term through December 31, 2026 and automatic 12-month renewal periods until terminated at the end of the initial term or any renewal term on 12-months' notice. Under the Feedstock Supply Agreement, Westlake agreed to sell OpCo ethane and other feedstock in amounts sufficient for OpCo to produce the ethylene to be sold under the Ethylene Sales Agreement. The price at which ethane and feedstock is sold includes an indexed price for spot gas liquids at Mont Belvieu and applicable transportation, storage and other costs.
Services and Secondment Agreement
OpCo and Westlake are parties to the Services and Secondment Agreement, pursuant to which OpCo provides Westlake with various utilities and utility services and in exchange for Westlake providing OpCo with various utility services, comprehensive operating services for OpCo's units, services for the maintenance and operation of the common facilities and seconded employees to perform all services required under the agreement.
92
Lease Agreements
OpCo is obligated to Westlake under various long-term and short-term noncancelable operating leases, primarily related to rail car leases and land.
OpCo and Westlake are parties to two 50-year site lease agreements (the "Site Leases"). Under the Site Leases, OpCo leases the real property underlying Calvert City Olefins and Lake Charles Olefins and is granted certain use and access rights related thereto, for a base rental amount of $1 per year per site. Each of the Site Leases is terminable by the lessor upon the occurrence of certain events of default or by OpCo if Calvert City Olefins or Lake Charles Olefins, as applicable, is destroyed by casualty. Pursuant to the Site Leases, the lessor has the right to restore and repurchase the units for fair market value if OpCo fails to expeditiously restore Calvert City Olefins or Lake Charles Olefins, as applicable, following a casualty loss. Subject to the foregoing repurchase right, OpCo may remove its ethylene production facilities and other related improvements for up to one year after expiration or termination of the applicable Site Lease, so long as such removal can be accomplished without material damage or harm to the lessor's property or operations; provided that any assets that are not timely removed by OpCo will be deemed to have been surrendered to the lessor.
Omnibus Agreement
We, OpCo and Westlake are parties to the Omnibus Agreement, pursuant to which we granted Westlake, among other things, a right of first refusal on any proposed transfer of our equity interests in OpCo, the ethylene production facilities that serve Westlake's other facilities, or certain other assets we may acquire from Westlake. The Omnibus Agreement also provides for reimbursement to Westlake for the provision of various administrative and professional services and direct expenses incurred on our behalf and in connection with the operation of our business, including, but not limited to, legal, accounting services, audit services, human resources, insurance, tax, credit, finance, government affairs and regulatory affairs. Under the Omnibus Agreement, Westlake will indemnify us against certain environmental and other losses, and we will indemnify Westlake against certain environmental and other losses for which Westlake is not otherwise obligated to indemnify us and certain other losses and liabilities to the extent resulting from the provision of services by Westlake to us.
OpCo Partnership Agreement
We, OpCo GP and Westlake are parties to an amended and restated agreement of limited partnership of OpCo (the "OpCo LP Agreement"). The OpCo LP Agreement governs the ownership and management of OpCo and designates OpCo GP as the general partner of OpCo. OpCo GP generally has complete authority to manage OpCo's business and affairs. We control OpCo GP, as its sole member, subject to certain approval rights held by Westlake. The OpCo LP Agreement was amended in December 2017 in connection with the passage of the Bipartisan Budget Act of 2015, which amended certain partnership tax audit rules.
OpCo Revolver
On August 4, 2014, OpCo entered into a $600 million senior unsecured revolving credit facility agreement with Westlake (as subsequently amended, the "OpCo Revolver"). The OpCo Revolver matures on July 12, 2027. Borrowings under the OpCo Revolver bear interest at a variable rate of either (a) SOFR plus the Applicable Margin plus a 0.10% credit spread adjustment or (b) if SOFR is no longer available, the Alternate Base Rate plus the Applicable Margin minus 1.0%. The Applicable Margin under the OpCo Revolver is 1.75%.
MLP Revolver
On April 29, 2015, we entered into a $300 million revolving credit facility agreement with an affiliate of Westlake (as subsequently amended, the "MLP Revolver") to fund our purchase of an additional 2.7% newly-issued, limited partner interest in OpCo for approximately $135.3 million. In 2017, we entered into an amendment to the MLP Revolver credit agreement, increasing borrowing capacity from $300 million to $600 million. On March 29, 2019, we borrowed approximately $123.5 million under the MLP Revolver to partially fund the purchase of the additional 4.5% interest in OpCo. The MLP Revolver matures on July 12, 2027. Borrowings under the MLP Revolver bear interest at a variable rate of either (a) SOFR plus the Applicable Margin plus a 0.10% credit spread adjustment or (b) if SOFR is no longer available, the Alternate Base Rate plus the Applicable Margin minus 1.0%. The Applicable Margin under the MLP Revolver varies between 1.75% and 2.75%, depending on our Consolidated Leverage Ratio. The MLP Revolver provides that we may pay all or a portion of the interest on any borrowings in kind, in which case any such amounts would be added to the principal amount of the loan.
93
Exchange Agreement
OpCo and Westlake are parties to an exchange agreement, which had an initial term through August 1, 2015 and is continuing year to year thereafter, unless and until terminated by either party. Under the exchange agreement, OpCo may require Westlake to deliver up to 200 million pounds of ethylene for OpCo per year from the Site Leases to an ethylene hub in Mt. Belvieu, Texas, for which OpCo would be required to pay Westlake an exchange fee of $0.006 per pound.
Investment Management Agreement
On August 1, 2017, we, OpCo and Westlake executed an Investment Management Agreement that authorizes Westlake to invest our and OpCo's excess cash with Westlake for durations of up to a maximum of nine months. Per the terms of the Investment Management Agreement, we earn a market return plus five basis points and Westlake provides daily availability of the invested cash to meet any liquidity needs of us or OpCo.

WESTLAKE CHEMICAL PARTNERS LP
Insider Trading Policy
Revised and effective as of May 10, 2023
I.PURPOSE & SCOPE
1.0 In the normal course of business, the officers, directors, and employees of the general partner of Westlake Chemical Partners LP (the “Partnership”) and its subsidiaries and affiliates (collectively, “WLKP”) may come into possession of significant, sensitive information related to WLKP, another company with which WLKP is conducting business, or a possible transaction between WLKP and another company. This policy sets forth WLKP’s guidelines for the handling of confidential information and focuses specifically on confidential information with respect to U.S. federal securities laws related to “insider trading”. Further, the purpose of this policy statement is to:
•inform persons that are affiliated with WLKP of their responsibilities in this area of the law;
•establish a policy for those persons to follow to maintain confidentiality of information related to WLKP and other companies and to prevent misuse of that information; and
•explain the consequences of violating the law and this policy.
II. POLICY
2.0 U.S. Insider Trading Laws: The Partnership is a registrant with the Securities and Exchange Commission (“SEC”) and as such is subject to the U.S. federal insider-trading laws. These laws generally prohibit any director, officer, board member or employee of WLKP who possesses material non-public information concerning WLKP or another public company from buying or selling securities of WLKP or the other company or passing on that information to others, such as friends or family members, who do so. It is WLKP’s policy that all personnel must refrain from insider trading of the securities of WLKP and other public companies in violation of federal law.
2.1 Compliance: All WLKP officers, directors, and employees must strictly comply with this policy. Moreover, no person should engage in any transaction in which he or she may even appear to be trading while in possession of inside information. Failure to observe this policy may result in serious legal difficulties for the employee, as well as WLKP. Persons violating this policy will be subject to disciplinary action, up to and including dismissal from WLKP.
2.2 Restrictions on Purchases and Sales: It is WLKP’s policy that if you possess material non-public information concerning WLKP or another company, neither you nor your spouse, minor children, or other adults living in your household, nor any family members who do not live in your household but whose transactions in securities of WLKP or another company are directed by you or subject to your influence or control,
nor any entity controlled by you, may (i) buy or sell securities of WLKP or such other company (or options on such securities) or (ii) pass on such information to others.
2.3 Policy on Maintaining Confidentiality: All officers, directors, and employees should avoid communicating non-public company information to any person (including family members and friends) unless the person has a need to know the information for an appropriate business-related reason. This policy applies without regard to the materiality of the information. Consistent with the foregoing, officers, directors, and employees should be discreet with non-public information and refrain from discussing it in public places where it can be overheard, such as elevators, restaurants, and on public transportation. To avoid even the appearance of impropriety, you should at all times refrain from providing advice or making recommendations regarding the purchase or sale of the Partnership’s securities or the securities of other companies of which you have knowledge as a result of employment or association with WLKP. If an officer, director, or employee communicates information that someone else uses to trade illegally in securities, the legal penalties described in this policy are applicable, whether or not any personal benefit was derived from the illegal trading.
III. RULE 10B5-1 TRADING PLANS
3.0 Plan Requirements: The Partnership requires that all trading plans adopted under Rule 10b5-1 of the Securities Exchange Act of 1934 (“Rule 10b5-1”) by an officer, employee or director be approved in writing by the Legal Department in advance of such adoption or amendment. A Rule 10b5-1 trading plan must be in writing and specify (including by formula) the amounts of, dates of, and prices at which the securities are to be traded or delegate discretion on those matters to an independent third party. A Rule 10b5-1 trading plan may not be adopted when the officer, employee or director is in possession of material nonpublic information about the Partnership. An officer, employee or director who wishes to enter into a Rule 10b5-1 trading plan must submit a written certification to the Legal Department certifying that the plan meets all of the requirements set forth in Rule 10b5-1, that such officer, employee or director is not aware of any material nonpublic information about the Partnership at such time, and that such officer, employee or director is adopting the plan in good faith and not as part of a plan or scheme to evade the prohibitions on insider trading.
3.2 Transactions Pursuant to a 10b5-1 Trading Plan: If such certification is provided and the trading plan meets the requirements of Rule 10b5-1, this policy permit officers, directors, employees and consultants to trade in Partnership securities regardless of their awareness of material nonpublic information. Once the Rule 10b5-1 trading plan is adopted, the officer, employee or director must not exercise any influence over the number of securities to be traded, the price at which they are to be traded or the date of the trade. If the officer, employee or director modifies or changes the number of securities to be purchased or sold, price or timing of the purchase or sale, or the formula, price or timing of the purchase or sale of securities, it will be deemed under Rule 10b5-1 to be a termination of the Rule 10b5-1 trading plan and the adoption of a new Rule 10b5-1 trading plan. Overlapping Rule 10b5-1 trading plans will not be approved if the overlapping plan does not fit within one of the exceptions specified in Rule 10b5-1.
2
3.3 Cooling Off Period: The first transaction under a Rule 10b5-1 trading plan may not be made until the later of (i) ninety (90) days after the adoption of the Rule 10b5-1 plan and (ii) two business days after the release of the Partnership’s financial results for the quarter in which the plan was adopted or modified.
IV. RESPONSIBILITIES
4.0 Employees: Each employee is responsible to ensure his/her individual compliance with this policy and the corresponding law. Employees are further responsible to report any violations of this policy. They may do so by contacting the General Counsel.
4.1 Managers and Executives: Each manager and executive is responsible to ensure that all employees under his/her charge are made aware of the applicable provisions of this policy and to provide the necessary clarification and instructions to ensure compliance.
4.2 Legal Department: The Legal Department is charged with the administration of this policy to include: monitoring compliance, reviewing and recommending changes to the President and CEO, informing and training employees and responding to questions of officers, directors or employees of WLKP.
4.3 Modifications: The President and CEO is authorized to approve any changes to this policy.
V. BLACKOUT PERIODS
5.0 Quarterly Blackout Periods: The Partnership’s announcement of its quarterly financial results almost always has the potential to have a material effect on the market for Partnership securities. Therefore, to avoid even the appearance of trading while aware of material nonpublic information, directors, officers and those employees designated on the “insider trading list” are prohibited from trading, and will not be pre-cleared to trade in Partnership securities, during the period beginning on the first business day of the month following the month that includes the 15th business day after the Partnership’s issuance of its quarterly earnings release and ending after the first full business day following the Partnership’s issuance of its next quarterly earnings release. From time to time, the General Counsel may, in consultation with the Chief Financial Officer, reduce, expand or otherwise amend the blackout periods.
3
5.1 Event-specific Blackout Periods: From time to time, an event may occur that is material to the Partnership and is known by only a few employees with material non-public information, directors and officers. So long as the event remains material and non-public, employees with material non-public information, directors and officers may not trade in Partnership securities. The existence of an event-specific blackout will not be announced, other than to those who are aware of the event giving rise to the blackout. If, however, a person whose trades are subject to pre-clearance requests permission to trade in Partnership securities during an event-specific blackout, the Legal Department may inform the requester of the existence of a blackout period, without disclosing the reason for the blackout. Any person made aware of the existence of an event-specific blackout should not disclose the existence of the blackout to any other person. The failure of the Legal Department to designate a person as being subject to an event-specific blackout will not relieve that person of the obligation not to trade while aware of material nonpublic information.

DETAILED POLICY INFORMATION AND DEFINITIONS
I. FEDERAL INSIDER-TRADING LAWS
Summary of the Law. Federal insider-trading laws generally prohibit any officer, director, or employee (or any person related to an officer, director or employee) of WLKP who possesses material, non-public information (also referred to as “inside information”) relating to WLKP or another public company from buying or selling securities of WLKP or such other company or any publicly traded options on WLKP’s or that other company’s securities, or engaging in any other action to take advantage of, or pass on to others, that information. The mere fact that a person knows the information is generally enough to bar him or her from trading, even if the reasons for the potential trade are not based on that information.
Materiality. Information is considered “material” if there is a substantial likelihood that a reasonable investor would consider that information (whether positive or negative) important in making a decision to buy, hold or sell securities, or such information could affect the price of the security. There is no bright-line standard for assessing materiality; rather, materiality is based on an assessment of facts and circumstances, and is often evaluated by enforcement authorities with the benefit of hindsight. By way of example, it is probable that the following information, in most circumstances, would be deemed material:
•annual, quarterly or monthly financial results;
•a change in earnings or earnings projections or other earnings guidance;
•negotiations and agreements regarding, or the occurrence of, a significant pending or proposed merger, acquisition, business combination or tender offer;
•material developments with creditors or significant changes in credit facilities or financing sources;
•impending announcements of bankruptcy or financial liquidity problems;
•a significant sale of assets or the disposition of a subsidiary;
•significant changes in prices, customers or suppliers;
•planned changes in dividend policies;
•declaration of a stock split or the offering of additional debt or equity securities;
•entering into of significant new contracts or the non-performance by a party under a significant existing contract;
•significant threatened litigation or significant developments in existing litigation;
•significant labor disputes;
•significant contracts;
•significant changes in the value of our derivatives portfolio;
•top management changes; and
•significant new products or discoveries, or results of important research and development.
5
This list is not intended to be exhaustive; other types of information may also be material. Before engaging in any securities transactions, officers, directors, and employees should consider carefully how the SEC and others might view such a transaction in hindsight.
When Information is Public. Information is considered “public” and no longer “inside” only after it has been effectively disclosed in a manner sufficient to ensure its availability to the investing public. This disclosure generally requires reporting on the Dow Jones tapes in the United States, the Associated Press or another wire service, Reuters Economic Services, or in the newspapers in major financial areas, or disclosure in filings with the SEC. Selective disclosure to a few persons does not make information public. Furthermore, adequate dissemination requires allowing enough time after the announcement for the market to react to the information. Generally, information will be deemed for purposes of this policy to have been adequately disseminated to and absorbed by the market by the beginning of the third business day after (and including) the date of its release to the communications media.
Tipping. Information that could have an impact on a company’s securities prices, including customers, suppliers, or potential parties to contracts, must not be passed on to other companies or people (such as family members, friends, relatives or business associates). When “tipping” occurs, both the “tipper” and the “tippee” may be held liable, and this liability may extend to all those to whom the tippee gives the information. The legal penalties described in this policy are applicable whether or not a person derives any benefit from another’s actions.
II. COMPLIANCE AND PENALTIES
Surveillance. The SEC and the national securities exchanges in the U.S. have extensive surveillance facilities that are used to monitor trading in stocks and other securities. Frequently, these institutions have cooperative arrangements with comparable institutions outside the U.S. If a security transaction becomes the subject of scrutiny, the transaction will be viewed after the fact. As a result, before engaging in any transaction, all persons covered by this policy should carefully consider how regulators and others might view the transaction in hindsight.
Penalties. The consequences of insider-trading violations can be severe under federal law. The SEC takes the position that these laws apply to all transactions in securities or options of companies listed for trading in the U.S., whether or not the actual trades take place in the U.S. For individuals who trade on inside information (or tip information to others), penalties include:
•a civil penalty of disgorgement, or return, of profit gained or loss avoided, plus a fine of up to three times the profit gained or loss avoided;
•a criminal fine (no matter how small the profit) of up to $5 million; and
•a jail term of up to 20 years.
In addition to civil and criminal penalties, persons contemporaneously trading at the time of a violation of the insider trading laws have the right to sue the insider for an amount equal to the profit gained or loss avoided by the insider in such transaction, offset by any amounts the insider is required to disgorge by the SEC.
For a company (as well as any supervisory person of a company) that fails to take appropriate steps to prevent illegal trading, penalties include:
6
•a civil penalty of up to the greater of $1 million or three times the profit gained or loss avoided as a result of the employee’s violation; and
•a criminal penalty of up to $25 million.
Disciplinary Action by the Partnership. Persons who violate this Policy shall be subject to disciplinary action by the Partnership, which may include termination or other appropriate action.
