Industry and corporate responsibility leadership: catalyzing and leading the way for positive change to benefit human health and society

Industry leadership

•In November 2020, Alexandria was ranked as the #1 public REIT for construction-in-progress in 2019 from Engineering News-Record’s (ENR) Top 50 List. ENR recognizes leaders in the construction industry, and its top ranking of our construction activity highlights our commitment to creating and delivering life-changing and essential facilities to our tenant community.

•In December 2020, we achieved the following in the 2020 Global Real Estate Sustainability Benchmark (“GRESB”) Real Estate Assessment: (i) #1 global ranking in the Science & Technology sector, (ii) #1 global ranking and 5 Star Rating (out of 5 stars) in our Diversified Listed Peer Group for highly sustainable development initiatives, and (iii) our third consecutive “A” disclosure score.

Pioneering social responsibility initiatives to continue to drive unique, disruptive, and highly impactful solutions to tackle some of society’s most complex and pressing challenges

Alexandria is profoundly committed to driving forward significant collaborative and innovative solutions to address some of today’s most urgent and widespread societal challenges, including the COVID-19 pandemic, the opioid epidemic, and the educational achievement gap.

At the vanguard and heart of the life science ecosystem’s fight against COVID-19

•As a testament to our comprehensive and industry-leading COVID‑19 prevention guidelines and practices, in October 2020, we became the first-ever company to achieve a Fitwel Viral Response Certification with Distinction, the highest designation within the new Viral Response Module developed by the world’s leading healthy building certification system. Additionally, in November 2020, we achieved the world’s first WELL Health-Safety Rating for Laboratory Space at Alexandria LaunchLabs® – New York City. This latest evidence-based, third-party verified rating further affirms our longstanding and robust practices to help keep our tenants, employees, visitors, service providers, and key industry stakeholders healthy and safe.

•Throughout the COVID-19 pandemic, Alexandria has been a critical partner to several impactful organizations supporting communities adversely affected by the COVID-19 pandemic. In total, Alexandria has donated more than $1 million to non-profit organizations on the front lines of combating the devastating impact of the COVID-19 pandemic, including Robin Hood, New York City’s largest poverty-fighting organization. As a member of the Robin Hood Board of Directors, Joel Marcus has played a key leadership role in the distribution of over $60 million to 575 organizations across all five New York City boroughs, providing critical emergency support for New Yorkers in need through food, housing, financial assistance, job security, and more.

•In lieu of tenant holiday gifts, in December 2020, Alexandria made donations to several regional COVID-19-related non-profit programs, including Seattle Foundation’s COVID-19 Relief Fund, Robin Hood COVID-19 Relief Fund, SF New Deal COVID-19 Relief for San Francisco, Nourish Now in Maryland, and the Greg Hill Foundation’s Restaurant Strong Fund in Boston.

Pioneering a groundbreaking, data-driven, and evidence-based model to help solve the opioid epidemic

•Determined to reverse the trajectory of the U.S. opioid epidemic, which is one of the most pervasive public health challenges in our nation’s history, Alexandria partnered with Verily Life Sciences to establish an innovative, non-profit healthcare ecosystem dedicated to the full and sustained recovery of people living with addiction. Together, we pioneered a fully integrated campus in Dayton, Ohio, to house an evidence-based comprehensive treatment model encompassing a full continuum of care with dedicated facilities and services for treatment, residential housing, group therapy, family reunification, workforce development programs, job placement, and community transition.

•Over the last year, we completed construction of the OneFifteen Outpatient Clinic; the Crisis Stabilization Unit; and most recently, OneFifteen Living, the residential housing component that opened in late 2020.

•Overdose deaths continue to rise dramatically during the COVID-19 pandemic, demonstrating the tremendous need for the OneFifteen ecosystem. Since opening in the fall of 2019, OneFifteen has made a positive and comprehensive impact on the local community and the way addiction is treated, seeing approximately 2,200 patients in 2020, including over 1,150 people during the three months ended December 31, 2020. It is our hope that OneFifteen’s unique approach to treatment will serve as a model of recovery for the rest of the country to replicate.

Building educational foundations for students to pave paths for long-term success and close the achievement gap

•Alexandria is deeply committed to driving educational opportunities and providing the support and resources needed to build the foundations for underserved, low-income students to succeed and become engaged and leading members of society. Understanding that education is one of the most fundamental foundations for a safe, healthy, and good life and essential for opportunity and economic mobility, we have forged deep partnerships in our communities with highly impactful organizations that provide holistic educational resources to underserved populations.

•In December 2020, Alexandria celebrated the culmination of the Emily Krzyzewski Center’s $15 million Game Changer Campaign, in which Alexandria played a critical leadership role. The Emily K Center paves a path to success in higher education for academically focused, low-income K–12 students in Durham, North Carolina. Students receive holistic support that encompasses academic skills development, personal management and leadership training, college planning, and career exploration. Of those who complete Emily K’s Scholars to College program, nearly 100% are accepted to college each year.

•The campaign funds will support ongoing programs to prepare students for life-changing college access while bolstering their achievement and developing their character and leadership; an endowment to ensure support for students in years to come; and a new 7,500 square foot facility designed for the specific needs of college-access programs to provide much needed classroom space as well as rooms for quiet study and one-on-one advising and financial aid discussions.

Alexandria Fighting COVID-19 on Multiple Fronts
---
December 31, 2020

Alexandria and our innovative tenants are at the vanguard and heart of the life science ecosystem advancing solutions for COVID-19

Safe and effective vaccines and therapies, in addition to widespread testing, continue to be critically needed to combat the global COVID-19 pandemic. By maintaining essential continuous operations across our campuses, Alexandria has enabled several of our life science tenants to pursue mission-critical COVID-19-related research and development. The heroic work being done by so many of our tenants and campus community members to help test for, treat, and prevent COVID-19, as well as provide medical supplies and protective equipment to neighboring hospitals, is profound and inspiring. We are currently tracking approximately 100 tenants across our cluster markets that have contributed meaningful time and resources to advancing solutions for COVID-19.

Developing preventative vaccines

A prophylactic vaccine is critically needed to resolve the global COVID-19 pandemic. As such, researchers around the world are working tirelessly to develop a safe and effective vaccine in record time. Furthermore, to help expedite the development, manufacturing, and distribution of COVID-19 vaccines, the U.S. government initiated an unprecedented public-private collaboration, allocating several billions of dollars to these efforts.

This support along with the internal vaccine development expertise and innovative technology platforms of our tenants Pfizer Inc. (in partnership with BioNTech) and Moderna, Inc. (in partnership with the National institutes of Health), culminated in the FDA providing Emergency Use Authorization (“EUA”) in December 2020 for their respective mRNA based COVID-19 vaccines. The U.S. has begun a large-scale COVID-19 vaccination campaign and will continue to roll out vaccines across the nation, prioritizing frontline and essential workers, the elderly, and individuals considered high-risk.

Additional tenants, including AstraZeneca plc, Emergent BioSolutions Inc., FUJIFILM Diosynth Biotechnologies, GlaxoSmithKline, Johnson & Johnson, Novavax, Inc., and Sanofi, have similarly received strong government support for their efforts in the development, manufacturing, and/or distribution of COVID-19 vaccines. Many of these companies will report critical trial data over the coming months, which, if positive, could help bolster the widespread delivery of a safe and effective COVID-19 vaccine around the world.

Advancing new and repurposed therapies

Safe and effective therapies are important for mitigating the impact of COVID-19, decreasing hospitalizations, and improving patient outcomes overall. On October 22, 2020, the FDA approved Veklury® (remdesivir), developed by our tenant Gilead Sciences, Inc., as the first antiviral treatment approved for COVID-19 patients requiring hospitalization. Subsequently, in November 2020, the FDA granted EUAs to tenant Eli Lilly and Company’s bamlanivimab for the treatment of newly infected high-risk patients with mild or moderate disease, as well as to Regeneron Pharmaceutical’s antibody cocktail for a similar indication.

In addition, over 300 experimental therapies to treat COVID-19 are being studied in over 900 clinical trials around the world, as well as over more than 150 therapeutic candidates in preclinical development. A substantial number of these programs are sponsored by our tenants, including the following:

•Vir Biotechnology, Inc. and GlaxoSmithKline announced on October 6, 2020, that their most advanced antibody therapy for the early treatment of patients with COVID-19 has entered Phase III and that they expect complete results in the first quarter of 2021.

•AbbVie Inc., Amgen, AstraZeneca plc, Atreca Inc., Enanta Pharmaceuticals, Inc., Novartis AG, and Pfizer Inc. are similarly endeavoring to develop novel therapies and repurpose existing and investigational drugs to provide near-term treatments for moderate and severe COVID-19 patients and those at highest risk.

Improving testing quality and capacity

Abbott Laboratories, Adaptive Biotechnologies Corporation, Color, Cue Health Inc., Laboratory Corporation of America Holdings, Quest Diagnostics, Quidel Corporation, Roche, Thermo Fisher Scientific Inc., Verily Life Sciences, and others are working to improve testing quality, capacity, and turnaround time to more effectively determine who has an active COVID-19 infection, who has been exposed to the virus, and who has developed immunity against it. The increased availability of widespread COVID-19 testing is critical for curtailing the pandemic and facilitating a safer reopening of workplaces, communities, and society overall.

We present our equity investments at fair value whenever fair value or net asset value (“NAV”) is readily available. Adjustments for our limited partnership investments represent changes in reported NAV as a practical expedient to estimate fair value. For investments without readily available fair values, we adjust the carrying amount whenever such investments have an observable price change, and further adjustments are not made until another price change, if any, is observed. Refer to “Investments” in the “Definitions and reconciliations” of this Supplemental Information for additional details.

(1)Represents the weighted-average interest rate as of the end of the applicable period, including expense/income related to the amortization of loan fees, amortization of debt premiums (discounts), and other bank fees.

(2)The commercial paper notes bear interest at short-term fixed rates and can generally be issued with a maturity of 30 days or less and with a maximum maturity of 397 days from the date of issuance. Borrowings under the program are used to fund short-term capital needs and are backed by our unsecured senior line of credit. The commercial paper outstanding as of December 31, 2020, matured on January 13, 2021. In the event we are unable to issue commercial paper notes or refinance outstanding borrowings under terms equal to or more favorable than those under our unsecured senior line of credit, we expect to borrow under the unsecured senior line of credit at L+0.825%. As such, we calculate the weighted-average remaining term of our commercial paper using the maturity date of our unsecured senior line of credit. Using the maturity date of our outstanding commercial paper, the consolidated weighted-average maturity of our debt remains at 10.6 years. The commercial paper notes sold during the three months ended December 31, 2020, were issued at a weighted-average yield to maturity of 0.26% and had a weighted-average maturity term of 12 days.

Adjusted EBITDA margin	69%		67%			69%		68%		68%

(1)Includes the acceleration of stock compensation expense aggregating $4.5 million related to the resignation of an executive officer.

We use Adjusted EBITDA as a supplemental performance measure of our operations, for financial and operational decision-making, and as a supplemental means of evaluating period-to-period comparisons on a consistent basis. Adjusted EBITDA is calculated as earnings before interest, taxes, depreciation, and amortization (“EBITDA”), excluding stock compensation expense, gains or losses on early extinguishment of debt, gains or losses on sales of real estate, impairments of real estate, and significant termination fees. Adjusted EBITDA also excludes unrealized gains or losses and significant realized gains and impairments that result from our non-real estate investments. These non-real estate investment amounts are classified in our consolidated statements of operations outside of revenues.

We believe Adjusted EBITDA provides investors with relevant and useful information as it allows investors to evaluate the operating performance of our business activities without having to account for differences recognized because of investing and financing decisions related to our real

estate and non-real estate investments, our capital structure, capital market transactions, and variances resulting from the volatility of market conditions outside of our control. For example, we exclude gains or losses on the early extinguishment of debt to allow investors to measure our performance independent of our indebtedness and capital structure. We believe that adjusting for the effects of impairments and gains or losses on sales of real estate, significant impairments and gains on the sale of non-real estate investments, and significant termination fees allows investors to evaluate performance from period to period on a consistent basis without having to account for differences recognized because of investing and financing decisions related to our real estate and non-real estate investments or other corporate activities that may not be representative of the operating performance of our properties.

In addition, we believe that excluding charges related to stock compensation and unrealized gains or losses facilitates for investors a comparison of our business activities across periods without the volatility resulting from market forces outside of our control. Adjusted EBITDA has limitations as a measure of our performance. Adjusted EBITDA does not reflect our historical expenditures or future requirements for capital expenditures or contractual commitments. While Adjusted EBITDA is a relevant measure of performance, it does not represent net income (loss) or cash flows from operations calculated and presented in accordance with GAAP, and it should not be considered as an alternative to those indicators in evaluating performance or liquidity.

In order to calculate Adjusted EBITDA margin, we also make comparable adjustments to our revenues. We adjust our total revenues by realized gains, losses, and impairments related to our non-real estate investments and significant termination fees to arrive at revenues, as adjusted. Our calculation of Adjusted EBITDA margin divides Adjusted EBITDA by our revenues, as adjusted. We believe that consistent application of these comparable adjustments to both components of Adjusted EBITDA margin provides a more useful calculation for the comparison across periods.

Annual rental revenue

Annual rental revenue represents the annualized fixed base rental obligations, calculated in accordance with GAAP, for leases in effect as of the end of the period, related to our operating RSF. Annual rental revenue is presented using 100% of the annual rental revenue of our consolidated properties and our share of annual rental revenue for our unconsolidated real estate joint ventures. Annual rental revenue per RSF is computed by dividing annual rental revenue by the sum of 100% of the RSF of our consolidated properties and our share of the RSF of properties held in unconsolidated real estate joint ventures. As of December 31, 2020, approximately 94% of our leases (on an RSF basis) were triple net leases, which require tenants to pay substantially all real estate taxes, insurance, utilities, repairs and maintenance, common area expenses, and other operating expenses (including increases thereto) in addition to base rent. Annual rental revenue excludes these operating expenses recovered from our tenants. Amounts recovered from our tenants related to these operating expenses, along with base rent, are classified in income from rentals in our consolidated statements of operations.

Cash interest

Cash interest is equal to interest expense calculated in accordance with GAAP plus capitalized interest, less amortization of loan fees and debt premiums (discounts). Refer to the definition of fixed-charge coverage ratio for a reconciliation of interest expense, the most directly comparable financial measure calculated and presented in accordance with GAAP, to cash interest.

Class A properties and AAA locations

Class A properties are properties clustered in AAA locations that provide innovative tenants with highly dynamic and collaborative environments that enhance their ability to successfully recruit and retain world-class talent and inspire productivity, efficiency, creativity, and success. Class A properties generally command higher annual rental rates than other classes of similar properties.

AAA locations are in close proximity to concentrations of specialized skills, knowledge, institutions, and related businesses. Such locations are generally characterized by high barriers to entry for new landlords, high barriers to exit for tenants, and a limited supply of available space.

Development, redevelopment, and pre-construction

A key component of our business model is our disciplined allocation of capital to the development and redevelopment of new Class A properties, and property enhancements identified during the underwriting of certain acquired properties, located in collaborative life science, technology, and agtech campuses in AAA urban innovation clusters. These projects are generally focused on providing high-quality, generic, and reusable spaces that meet the real estate requirements of, and are reusable by, a wide range of tenants. Upon completion, each value-creation project is expected to generate a significant increase in rental income, net operating income, and cash flows. Our development and redevelopment projects are generally in locations that are highly desirable to high-quality entities, which we believe results in higher occupancy levels, longer lease terms, higher rental income, higher returns, and greater long-term asset value.

Development projects generally consist of the ground-up development of generic and reusable facilities. Redevelopment projects consist of the permanent change in use of office, warehouse, and shell space into office/laboratory, tech office, or agtech space. We generally will not commence new development projects for aboveground construction of new Class A office/laboratory, tech office, and agtech space without first securing significant pre-leasing for such space, except when there is solid market demand for high-quality Class A properties.

Pre-construction activities include entitlements, permitting, design, site work, and other activities preceding commencement of construction of aboveground building improvements. The advancement of pre-construction efforts is focused on reducing the time required to deliver projects to prospective tenants. These critical activities add significant value for future ground-up development and are required for the vertical construction of buildings. Ultimately, these projects will provide high-quality facilities and are expected to generate significant revenue and cash flows.

Development, redevelopment, and pre-construction spending also includes the following costs: (i) certain tenant improvements and renovations that will be reimbursed, (ii) amounts to bring certain acquired properties up to market standard and/or other costs identified during the acquisition process (generally within two years of acquisition), and (iii) permanent conversion of space for highly flexible, move-in-ready office/laboratory space to foster the growth of promising early- and growth-stage life science companies.

Revenue-enhancing and repositioning capital expenditures represent spending to reposition or significantly change the use of a property, including through improvement in the asset quality from Class B to Class A.

Non-revenue-enhancing capital expenditures represent costs required to maintain the current revenues of a stabilized property, including the associated costs for renewed and re-leased space.

Dividend payout ratio (common stock)

Dividend payout ratio (common stock) is the ratio of the absolute dollar amount of dividends on our common stock (shares of common stock outstanding on the respective record dates multiplied by the related dividend per share) to funds from operations attributable to Alexandria’s common stockholders – diluted, as adjusted.

Dividend yield

Dividend yield for the quarter represents the annualized quarter dividend divided by the closing common stock price at the end of the quarter.

Fixed-charge coverage ratio

Fixed-charge coverage ratio is a non-GAAP financial measure representing the ratio of Adjusted EBITDA to fixed charges. We believe this ratio is useful to investors as a supplemental measure of our ability to satisfy fixed financing obligations and preferred stock dividends. Cash interest is equal to interest expense calculated in accordance with GAAP plus capitalized interest, less amortization of loan fees and debt premiums (discounts).

The following table reconciles interest expense, the most directly comparable financial measure calculated and presented in accordance with GAAP, to cash interest and fixed charges:

	Three Months Ended

Funds from operations and funds from operations, as adjusted, attributable to Alexandria’s common stockholders

GAAP-basis accounting for real estate assets utilizes historical cost accounting and assumes that real estate values diminish over time. In an effort to overcome the difference between real estate values and historical cost accounting for real estate assets, the Nareit Board of Governors established funds from operations as an improved measurement tool. Since its introduction, funds from operations has become a widely used non-GAAP financial measure among equity REITs. We believe that funds from operations is helpful to investors as an additional measure of the performance of an equity REIT. Moreover, we believe that funds from operations, as adjusted, allows investors to compare our performance to the performance of other real estate companies on a consistent basis, without having to account for differences recognized because of real estate acquisition and disposition decisions, financing decisions, capital structure, capital market transactions, variances resulting from the volatility of market conditions outside of our control, or other corporate activities that may not be representative of the operating performance of our properties.

On January 1, 2019, we adopted standards established by the Nareit Board of Governors in its November 2018 White Paper (the “Nareit White Paper”) on a prospective basis. The Nareit White Paper defines funds from operations as net income (computed in accordance with GAAP), excluding gains or losses on sales of real estate, and impairments of real estate, plus depreciation and amortization of operating real estate assets, and after adjustments for our share of consolidated and unconsolidated partnerships and real estate joint ventures. Impairments represent the write-down of assets when fair value over the recoverability period is less than the carrying value due to changes in general market conditions and do not necessarily reflect the operating performance of the properties during the corresponding period.

We compute funds from operations, as adjusted, as funds from operations calculated in accordance with the Nareit White Paper, excluding significant gains, losses, and impairments realized on non-real estate investments, unrealized gains or losses on non-real estate investments, gains or losses on early extinguishment of debt, gains or losses on early termination of interest rate hedge agreements, significant termination fees, acceleration of stock compensation expense due to the resignation of an executive officer, preferred stock redemption charges, deal costs, the income tax effect related to such items, and the amount of such items that is allocable to our unvested restricted stock awards. Neither funds from operations nor funds from operations, as adjusted, should be considered as alternatives to net income (determined in accordance with GAAP) as indications of financial performance, or to cash flows from operating activities (determined in accordance with GAAP) as measures of liquidity, nor are they indicative of the availability of funds for our cash needs, including our ability to make distributions.

The following table reconciles net income to funds from operations for the share of consolidated real estate joint ventures attributable to noncontrolling interests and our share of unconsolidated real estate joint ventures:

	Noncontrolling Interest Share of<br>Consolidated Real Estate JVs				Our Share of Unconsolidated <br>Real Estate JVs
	December 31, 2020				December 31, 2020

Funds from operations	$	30,681	$	118,145	$	6,569	$	27,205

Initial stabilized yield (unlevered)

Initial stabilized yield is calculated as the estimated amounts of net operating income at stabilization divided by our investment in the property. Our initial stabilized yield excludes the benefit of leverage. Our cash rents related to our value-creation projects are generally expected to increase over time due to contractual annual rent escalations. Our estimates for initial stabilized yields, initial stabilized yields (cash basis), and total costs at completion represent our initial estimates at the commencement of the project. We expect to update this information upon completion of the project, or sooner if there are significant changes to the expected project yields or costs.

•Initial stabilized yield reflects rental income, including contractual rent escalations and any rent concessions over the term(s) of the lease(s), calculated on a straight-line basis.

•Initial stabilized yield (cash basis) reflects cash rents at the stabilization date after initial rental concessions, if any, have elapsed and our total cash investment in the property.

Investment-grade or publicly traded large cap tenants

Investment-grade or publicly traded large cap tenants represent tenants that are investment-grade rated or publicly traded companies with an average daily market capitalization greater than $10 billion for the twelve months ended December 31, 2020, as reported by Bloomberg Professional Services. In addition, we monitor the credit quality and related material changes of our tenants. Material changes that cause a tenant’s market capitalization to decline below $10 billion, which are not immediately reflected in the twelve-month average, may result in their exclusion from this measure.

Investments

We hold investments in publicly traded companies and privately held entities primarily involved in the life science, technology, and agtech industries. We recognize, measure, present, and disclose these investments as follows:

		Statements of Operations
	Balance Sheet	Gains and Losses
	Carrying Amount	Unrealized	Realized
			Difference between proceeds received upon disposition and historical cost
Publicly traded companies	Fair value	Changes in fair value
Privately held entities without readily determinable fair values that:
Report NAV	Fair value, using NAV as a practical expedient	Changes in NAV, as a practical expedient to fair value
Do not report NAV	Cost, adjusted for observable price changes and impairments	Observable price changes	Impairments to reduce costs to fair value, which result in an adjusted cost basis and the differences between proceeds received upon disposition and adjusted or historical cost

For investments in privately held entities that do not report NAV per share, an observable price is a price observed in an orderly transaction for an identical or similar investment of the same issuer. Observable price changes result from, among other things, equity transactions for the same issuer executed during the reporting period, including subsequent equity offerings or other reported equity transactions related to the same issuer. For these transactions to be considered observable price changes of the same issuer, we evaluate whether these transactions have similar rights and obligations, including voting rights, distribution preferences, conversion rights, and other factors, to the investments we hold.

Joint venture financial information

We present components of balance sheet and operating results information related to our real estate joint ventures, which are not presented, or intended to be presented, in accordance with GAAP. We present the proportionate share of certain financial line items as follows: (i) for each real estate joint venture that we consolidate in our financial statements, which are controlled by us through contractual rights or majority voting rights, but of which we own less than 100%, we apply the noncontrolling interest economic ownership percentage to each financial item to arrive at the amount of such cumulative noncontrolling interest share of each component presented; and (ii) for each real estate joint venture that we do not control and do not consolidate, and are instead controlled jointly or by our joint venture partners through contractual rights or majority voting rights, we apply our economic ownership percentage to each financial item to arrive at our proportionate share of each component presented.

The components of balance sheet and operating results information related to our real estate joint ventures do not represent our legal claim to those items. For each entity that we do not wholly own, the joint venture agreement generally determines what equity holders can receive upon capital events, such as sales or refinancing, or in the event of a liquidation. Equity holders are normally entitled to their respective legal ownership of any residual cash from a joint venture only after all liabilities, priority distributions, and claims have been repaid or satisfied.

We believe this information can help investors estimate the balance sheet and operating results information related to our partially owned entities. Presenting this information provides a perspective not immediately available from consolidated financial statements and one that can supplement an understanding of the joint venture assets, liabilities, revenues, and expenses included in our consolidated results.

The components of balance sheet and operating results information related to our real estate joint ventures are limited as an analytical tool as the overall economic ownership interest does not represent our legal claim to each of our joint ventures’ assets, liabilities, or results of operations. In addition, joint venture financial information may include financial information related to the unconsolidated real estate joint ventures that we do not control. We believe that in order to facilitate for investors a clear understanding of our operating results and our total assets and liabilities, joint venture financial information should be examined in conjunction with our consolidated statements of operations and balance sheets. Joint venture financial information should not be considered an alternative to our consolidated financial statements, which are prepared in accordance with GAAP.

Key items included in net income attributable to Alexandria’s common stockholders

We present a tabular comparison of items, whether gain or loss, that may facilitate a high-level understanding of our results and provide context for the disclosures included in this Supplemental Information, our most recent annual report on Form 10-K, and our subsequent quarterly reports on Form 10-Q. We believe such tabular presentation promotes a better understanding for investors of the corporate-level decisions made and activities performed that significantly affect comparison of our operating results from period to period. We also believe this tabular presentation will supplement for investors an understanding of our disclosures and real estate operating results. Gains or losses on sales of real estate and impairments of held for sale assets are related to corporate-level decisions to dispose of real estate. Gains or losses on early extinguishment of debt, gains or losses on early termination of interest rate hedge agreements, and preferred stock redemption charges are related to corporate-level financing decisions focused on our capital structure strategy. Significant realized and unrealized gains or losses on non-real estate investments and impairments of real estate and non-real estate investments are not related to the operating performance of our real estate assets as they result from strategic, corporate-level non-real estate investment decisions and external market conditions. Impairments of non-real estate investments are not related to the operating performance of our real estate as they

represent the write-down of non-real estate investments when their fair values decline below their respective carrying values due to changes in general market or other conditions outside of our control. Significant items, whether a gain or loss, included in the tabular disclosure for current periods are described in further detail in this Supplemental Information and accompanying Earnings Press Release.

Lease accounting

On January 1, 2019, we adopted new lease accounting standards that set out the principles for the recognition, measurement, presentation, and disclosure of leases for both parties to a lease agreement (i.e., lessees and lessors). The new lease accounting standards did not result in material changes in neither the amount nor the timing of lease-related revenues that we recognized from our tenants. However, the new standards affected our financial statement presentation primarily in three specific areas.

Key differences between the prior accounting standard and the new lease accounting standards:

Prior to January 1, 2019, we classified rental revenues and tenant recoveries as separate line items on our consolidated statements of operations. Effective January 1, 2019, based on our election of a practical expedient, we are required to disclose the combined components of rental revenues and tenant recoveries as a single lease component, which is classified on our consolidated statements of operations as income from rentals. As a result, we do not disclose tenant recoveries as a separate GAAP revenue measure. Refer to the definition of tenant recoveries below for additional details on tenant recoveries revenue and its usefulness to investors.

The new lease accounting standard requires that lessors and lessees capitalize, as initial direct costs, only incremental costs of a lease that would not have been incurred if the lease had not been obtained. Effective January 1, 2019, costs that we incur to negotiate or arrange a lease, regardless of its outcome, such as for fixed employee compensation, tax, or legal advice to negotiate lease terms, and other costs, are expensed as incurred.

Under the package of practical expedients and optional transition method that we elected on January 1, 2019, we are not required to reassess whether initial direct leasing costs capitalized prior to the adoption of the new lease accounting standard in connection with the leases that commenced prior to January 1, 2019, qualify for capitalization under the new lease accounting standard. Therefore, we continue to amortize these initial direct leasing costs over the respective lease term.

In addition, the new lease accounting standards require companies to recognize a lease liability and a corresponding right-of-use asset on the consolidated balance sheets, and to represent the net present value of future rental payments related to operating leases in which we are the lessee. As a result, on January 1, 2019, we recognized a lease liability classified in accounts payable, accrued expenses, and other liabilities on our consolidated balance sheets, and a corresponding right-of-use asset included in other assets on our consolidated balance sheets, related to our ground leases existing as of January 1, 2019, for which we are the lessee. The net present value of the remaining future rental payments of our ground leases was calculated for each operating lease using the respective remaining lease term and a corresponding estimated incremental borrowing rate, which is the estimated interest rate that we would have to pay to borrow on a collateralized basis over a similar term for an amount equal to the lease payments.

Net cash provided by operating activities after dividends

Net cash provided by operating activities after dividends includes the deduction for distributions to noncontrolling interests. For purposes of this calculation, changes in operating assets and liabilities are excluded as they represent timing differences.

Net debt and preferred stock to Adjusted EBITDA

Net debt and preferred stock to Adjusted EBITDA is a non-GAAP financial measure that we believe is useful to investors as a supplemental measure in evaluating our balance sheet leverage. Net debt and preferred stock is equal to the sum of total consolidated debt less cash, cash equivalents, and restricted cash, plus preferred stock outstanding as of the end of the period. Refer to the definition of Adjusted EBITDA and Adjusted EBITDA margin for further information on the calculation of Adjusted EBITDA.

The following table reconciles debt to net debt and preferred stock and computes the ratio to Adjusted EBITDA:

Net operating income is a non-GAAP financial measure calculated as net income, the most directly comparable financial measure calculated and presented in accordance with GAAP, excluding equity in the earnings of our unconsolidated real estate joint ventures, general and administrative expenses, interest expense, depreciation and amortization, impairments of real estate, gains or losses on early extinguishment of debt, gains or losses on sales of real estate, and investment income or loss. We believe net operating income provides useful information to investors regarding our financial condition and results of operations because it primarily reflects those income and expense items that are incurred at the property level. Therefore, we believe net operating income is a useful measure for investors to evaluate the operating performance of our consolidated real estate assets. Net operating income on a cash basis is net operating income adjusted to exclude the effect of straight-line rent and amortization of acquired above- and below-market lease revenue adjustments required by GAAP. We believe that net operating income on a cash basis is helpful to investors as an additional measure of operating performance because it eliminates straight-line rent revenue and the amortization of acquired above- and below-market leases.

Furthermore, we believe net operating income is useful to investors as a performance measure for our consolidated properties because, when compared across periods, net operating income reflects trends in occupancy rates, rental rates, and operating costs, which provide a perspective not immediately apparent from net income or loss. Net operating income can be used to measure the initial stabilized yields of our properties by calculating net operating income generated by a property divided by our investment in the property. Net operating income excludes certain components from net income in order to provide results that are more closely related to the results of operations of our properties. For example, interest expense is not necessarily linked to the operating performance of a real estate asset and is often incurred at the corporate level rather than at the property level. In addition, depreciation and amortization, because of historical cost accounting and useful life estimates, may distort comparability of operating performance at the property level. Impairments of real estate have been excluded in deriving net operating income because we do not consider impairments of real estate to be property-level operating expenses. Impairments of real estate relate to changes in the values of our assets and do not reflect the current operating performance with respect to related revenues or expenses. Our impairments of real estate represent the write-down in the value of the assets to the estimated fair value less cost to sell. These impairments result from investing decisions or a deterioration in market conditions. We also exclude realized and unrealized investment income or loss, which results from investment decisions that occur at the corporate level related to non-real estate investments in publicly traded companies and certain privately held entities. Therefore, we do not consider these activities to be an indication of operating performance of our real estate assets at the property level. Our calculation of net operating income also excludes charges incurred from changes in certain financing decisions, such as losses on early extinguishment of debt, as these charges often relate to corporate strategy. Property operating expenses included in determining net operating income primarily consist of costs that are related to our operating properties, such as utilities, repairs, and maintenance; rental expense related to ground leases; contracted services, such as janitorial, engineering, and landscaping; property taxes and insurance; and property-level salaries. General and administrative expenses consist primarily of accounting and corporate compensation, corporate insurance, professional fees, office rent, and office supplies that are incurred as part of corporate office management. We calculate operating margin as net operating income divided by total revenues.

We believe that in order to facilitate for investors a clear understanding of our operating results, net operating income should be examined in conjunction with net income or loss as presented in our consolidated statements of operations. Net operating income should not be considered as an alternative to net income or loss as an indication of our performance, nor as an alternative to cash flows as a measure of our liquidity or our ability to make distributions.

Operating statistics

We present certain operating statistics related to our properties, including number of properties, RSF, occupancy percentage, leasing activity, and contractual lease expirations as of the end of the period. We believe these measures are useful to investors because they facilitate an understanding of certain trends for our properties. We compute the number of properties, RSF, occupancy percentage, leasing activity, and contractual lease expirations at 100% for all properties in which we have an investment, including properties owned by our consolidated and unconsolidated real estate joint ventures. For operating metrics based on annual rental revenue, refer to our discussion of annual rental revenue herein.

Same property comparisons

As a result of changes within our total property portfolio during the comparative periods presented, including changes from assets acquired or sold, properties placed into development or redevelopment, and development or redevelopment properties recently placed into service, the consolidated total income from rentals, as well as rental operating expenses in our operating results, can show significant changes from period to period. In order to supplement an evaluation of our results of operations over a given quarterly or annual period, we analyze the operating performance for all consolidated properties that were fully operating for the entirety of the comparative periods presented, referred to as same properties. We separately present quarterly and year-to-date same property results to align with the interim financial information required by the SEC in our management’s discussion and analysis of our financial condition and results of operations. These same properties are analyzed separately from properties acquired subsequent to the first day in the earliest comparable quarterly or year-to-date period presented, properties that underwent development or redevelopment at any time during the comparative periods, unconsolidated real estate joint ventures, properties classified as held for sale, and corporate entities (legal entities performing general and administrative functions), which are excluded from same property results. Additionally, termination fees, if any, are excluded from the results of same properties.

Stabilized occupancy date

The stabilized occupancy date represents the estimated date on which the project is expected to reach occupancy of 95% or greater.

Tenant recoveries

Tenant recoveries represent revenues comprising reimbursement of real estate taxes, insurance, utilities, repairs and maintenance, common area expenses, and other operating expenses and earned in the period during which the applicable expenses are incurred and the tenant’s obligation to reimburse us arises.

We classify rental revenues and tenant recoveries generated through the leasing of real estate assets within revenue in income from rentals in our consolidated statements of operations. We provide investors with a separate presentation of rental revenues and tenant recoveries in “Same Property Performance” of this Supplemental Information because we believe it promotes investors’ understanding of our operating results. We believe that the presentation of tenant recoveries is useful to investors as a supplemental measure of our ability to recover operating expenses under our triple net leases, including recoveries of utilities, repairs and maintenance, insurance, property taxes, common area expenses, and other operating expenses, and of our ability to mitigate the effect to net income for any significant variability to components of our operating expenses.

The following table reconciles income from rentals to tenant recoveries:

Unencumbered net operating income as a percentage of total net operating income

Unencumbered net operating income as a percentage of total net operating income is a non-GAAP financial measure that we believe is useful to investors as a performance measure of the results of operations of our unencumbered real estate assets as it reflects those income and expense items that are incurred at the unencumbered property level. Unencumbered net operating income is derived from assets classified in continuing operations, which are not subject to any mortgage, deed of trust, lien, or other security interest, as of the period for which income is presented.

The following table summarizes unencumbered net operating income as a percentage of total net operating income:

	Three Months Ended
(Dollars in thousands)	12/31/20		9/30/20		6/30/20		3/31/20		12/31/19
Unencumbered net operating income	$	315,586	$	388,575	$	296,358	$	295,001	$	270,903
Encumbered net operating income	11,367		16,024		16,687		15,815		15,359
Total net operating income	$	326,953	$	404,599	$	313,045	$	310,816	$	286,262
Unencumbered net operating income as a percentage of total net operating income	97%		96%		95%		95%		95%

Weighted-average interest rate for capitalization of interest

The weighted-average interest rate required for calculating capitalization of interest pursuant to GAAP represents a weighted-average rate based on the rates applicable to borrowings outstanding during the period, including expense/income related to interest rate hedge agreements, amortization of loan fees, amortization of debt premiums (discounts), and other bank fees. A separate calculation is performed to determine our weighted-average interest rate for capitalization for each month. The rate will vary each month due to changes in variable interest rates, outstanding debt balances, the proportion of variable-rate debt to fixed-rate debt, the amount and terms of interest rate hedge agreements, and the amount of loan fee and premium (discount) amortization.

The following table presents the weighted-average interest rate for capitalization of interest:

	Three Months Ended
	12/31/20	9/30/20	6/30/20	3/31/20	12/31/19
Weighted-average interest rate for capitalization of interest	3.66%	3.64%	4.03%	3.80%	3.88%

Weighted-average shares of common stock outstanding – diluted

From time to time, we enter into capital market transactions, including forward equity sales agreements (“Forward Agreements”), to fund acquisitions, to fund construction of our highly leased development and redevelopment projects, and for general working capital purposes. We are required to consider the potential dilutive effect of our forward equity sales agreements under the treasury stock method while the forward equity sales agreements are outstanding. As of December 31, 2020, we had Forward Agreements outstanding to sell an aggregate of 362 thousand shares of common stock.

Prior to the conversion of our remaining outstanding shares in October 2019, we considered the effect of assumed conversion of our outstanding 7.00% Series D Convertible Preferred Stock when determining potentially dilutive incremental shares to our common stock. When calculating the assumed conversion, we add back to net income or loss the dividends paid on our Series D Convertible Preferred Stock to the numerator and then include additional common shares assumed to have been issued (as displayed in the table below) to the denominator of the per share calculation. The effect of the assumed conversion is considered separately for our per share calculations of net income or loss; funds from operations, computed in accordance with the definition in the Nareit White Paper; and funds from operations, as adjusted. Prior to the conversion of our remaining outstanding shares in October 2019, our Series D Convertible Preferred Stock was dilutive and assumed to be converted when quarterly and annual basic EPS, funds from operations, or funds from operations, as adjusted, exceeded approximately $1.75 and $7.00 per share, respectively, subject to conversion ratio adjustments and the impact of repurchases of our Series D Convertible Preferred Stock. The effect of the assumed conversion was included when it was dilutive on a per share basis. The dilutive effect to both numerator and denominator may result in a per share effect of less than a half cent, which would appear as zero in our per share calculation, even when the dilutive effect to the numerator alone appears in our reconciliation.

The weighted-average shares of common stock outstanding used in calculating EPS – diluted, FFO per share – diluted, and FFO per share – diluted, as adjusted, during each period are calculated as follows:

	Three Months Ended					Year Ended
(In thousands)	12/31/20	9/30/20	6/30/20	3/31/20	12/31/19	12/31/20	12/31/19
