88 Bluxome Street is the first and only project to win full approval in Central SoMa

In July 2019, we, along with TMG Partners, won full project approval to develop a 1.07 million RSF mixed-use campus at 88 Bluxome Street in Central SoMa. Anchored by a 490,000 RSF lease with Pinterest, Inc., the future development, which is the first and only project in Central SoMa to receive full approval and 100% of its Prop M allocation from the San Francisco Planning Commission, is nearly 60% pre-leased. Construction is expected to commence in 2020, and initial delivery is expected in 2022.

New issuance of $1.25 billion unsecured senior notes to elongate debt maturities

In July 2019, we opportunistically issued $1.25 billion of unsecured senior notes payable, with a weighted-average interest rate of 3.72% and a weighted-average maturity of 19.5 years. The proceeds were used to refinance $1.125 billion of unsecured senior notes payable and unsecured senior bank term loan, with a weighted-average interest rate of 3.94% and a weighted-average maturity of 2.4 years, with remaining proceeds used to reduce the outstanding balance of our unsecured senior line of credit. Upon completion of the refinancing, the pro forma weighted-average remaining term on our outstanding debt is 10.1 years, with no debt maturing until 2023.

Increased common stock dividend

Common stock dividend declared for 2Q19 of $1.00 per common share, up three cents, or 3.1%, over 1Q19; continuation of our strategy to share growth in cash flows from operating activities with our stockholders while also retaining a significant portion for reinvestment.

Corporate responsibility, industry leadership, and strategic initiatives

• In April 2019, we announced the launch of a new strategic agricultural technology (agtech) business initiative and the opening of Phase I of the Alexandria Center^® for AgTech – Research Triangle, the first and only fully integrated, amenity-rich, multi-tenant agtech R&D and greenhouse campus, in the heart of Research Triangle, the most important, dense, and diverse agtech cluster in the United States. The campus opened with a 97% leased, 175,000 RSF first phase redevelopment at 5 Laboratory Drive.

• In June 2019, we announced our partnership with Columbia University to open our second Alexandria LaunchLabs^® in New York City in the spring of 2020. The full-service platform will offer member companies 13,298 RSF of highly flexible, turnkey office/laboratory space and feature a high-tech event center to host workshops, networking events, and educational opportunities for the entrepreneurial life science community.

• In June 2019, we celebrated the opening of the first facilities within a tech-focused opioid rehabilitation campus in Dayton, Ohio. In partnership with Verily Life Sciences, LLC, we are leading the design and development of this 59,000 RSF state-of-the-art campus to provide a comprehensive model of care dedicated to the recovery of people suffering from opioid addiction.

Subsequent events

• In July 2019, we opportunistically issued $1.25 billion of unsecured senior notes payable, with a weighted-average interest rate of 3.72% and a weighted-average maturity of 19.5 years, including $750.0 million of 3.375% unsecured senior notes due 2031 and $500.0 million of 4.00% unsecured senior notes due 2050. The proceeds were used to refinance $1.125 billion of unsecured senior notes payable and unsecured senior bank term loan, with a weighted-average interest rate of 3.94% and a weighted-average maturity of 2.4 years, consisting of the following:

(i) Refinancing of an aggregate $950.0 million of unsecured senior notes payable comprising $400.0 million of 2.75% unsecured senior notes payable due 2020 and $550.0 million of 4.60% unsecured senior notes payable due 2022, pursuant to a cash tender offer completed on July 17, 2019, and subsequent call for redemption. The redemption is expected to settle on August 16, 2019.

(ii) Partial repayment of $175.0 million on our unsecured senior bank term loan. The remaining outstanding balance of the term loan will mature on January 2, 2025, if not repaid before maturity.

• As a result of our refinancing and partial repayment, we expect to recognize a loss, primarily related to the early extinguishment of debt, of $43 million, or $0.38 per share, in 3Q19.

• The remaining proceeds were used to reduce the outstanding balance of our unsecured senior line of credit.

• Upon completion of the refinancing, the pro forma weighted-average remaining term on our outstanding debt is 10.1 years, with no debt maturing until 2023.

• In July 2019, we acquired a 55% interest in 4224 and 4242 Campus Point Court and 10210 Campus Point Drive, located adjacent to our Campus Pointe by Alexandria campus in our University Town Center submarket of San Diego, for $140.3 million. The joint venture will include three operating properties aggregating 314,092 RSF, which are currently 83% occupied by multiple tenants. The properties, which have future value-creation opportunities, will be integrated into the current campus to create a 1.9 million RSF mega campus.

The asset base in North America includes 24.5 million RSF of operating properties and 1.5 million RSF of Class A properties undergoing construction, with projected initial occupancy in 2019, 2.2 million RSF of Class A properties undergoing construction or pre-construction, with projected initial occupancy in 2020, 4.4 million RSF of Class A properties undergoing or nearing pre-construction, with projected initial occupancy in 2021 or 2022, and 4.5 million of future development projects. Founded in 1994, Alexandria pioneered this niche and has since established a significant market presence in key locations, including Greater Boston, San Francisco, New York City, San Diego, Seattle, Maryland, and Research Triangle. Alexandria has a longstanding and proven track record of developing Class A properties clustered in urban life science, technology, and agtech campuses that provide our 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. Alexandria also provides strategic capital to transformative life science and technology companies through our venture capital arm.

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.

Summary of Debt
June 30, 2019

Debt maturities chart⁽¹⁾ 

(In millions)

Pro Forma Weighted-Average Remaining Term of 10.1 Years⁽¹⁾ 

(1) In July 2019, we opportunistically issued $1.25 billion of unsecured senior notes payable, with a weighted-average interest rate of 3.72% and a weighted-average maturity of 19.5 years, including $750.0 million of 3.375% unsecured senior notes due 2031 and $500.0 million of 4.00% unsecured senior notes due 2050. The proceeds were used to refinance $1.125 billion of unsecured senior notes payable and unsecured senior bank term loan, with a weighted-average interest rate of 3.94% and a weighted-average maturity of 2.4 years, consisting of the following:

(i) Refinancing of an aggregate $950.0 million of unsecured senior notes payable comprising $400.0 million of 2.75% unsecured senior notes payable due 2020 and $550.0 million of 4.60% unsecured senior notes payable due 2022, pursuant to a cash tender offer completed on July 17, 2019, and subsequent call for redemption. The redemption is expected to settle on August 16, 2019.

(ii) Partial repayment of $175.0 million on our unsecured senior bank term loan. The remaining outstanding balance of the term loan will mature on January 2, 2025, if not repaid before maturity.

• As a result of our refinancing and partial repayment, we expect to recognize a loss, primarily related to the early extinguishment of debt, of $43 million in 3Q19.

• The remaining proceeds were used to reduce the outstanding balance of our unsecured senior line of credit.

• Upon completion of the refinancing, the pro forma weighted-average remaining term on our outstanding debt is 10.1 years, with no debt maturing until 2023.

(2) Represents balance outstanding as of June 30, 2019. See footnote 1 for refinancing subsequent to June 30, 2019.

(3) We generally have limited outstanding borrowings under our $2.2 billion unsecured senior line of credit as of December 31. Our average outstanding balance as of December 31 for the past three years under our unsecured senior line of credit has been approximately $109.3 million. Additionally, we generally amend and extend the maturity date of our unsecured senior line of credit every two to three years.

Adjusted EBITDA margin	69%			70%			69%			69%			69%

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, and impairments of real estate. 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 real estate and non-real estate investment and disposition decisions, financing decisions, 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, and significant impairments and significant gains on the sale of non-real estate investments allows investors to evaluate performance from period to period on a consistent basis without having to account for differences recognized because of real estate and non-real estate investment and disposition decisions. 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.

Our calculation of Adjusted EBITDA margin divides Adjusted EBITDA by our revenues, as adjusted. We believe that revenues, as adjusted, provides a denominator for Adjusted EBITDA margin that is calculated on a basis more consistent with that of the Adjusted EBITDA numerator. Specifically, revenues, as adjusted, includes the same realized gains on, and impairments of, non-real estate investments that are included in the reconciliation of Adjusted EBITDA. We believe that the consistent application of results from our non-real estate investments to both the numerator and denominator 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 amount, 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 June 30, 2019, approximately 97% 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.

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 investment and disposition decisions, financing decisions, capital structure, capital market transactions, and variances resulting from the volatility of market conditions outside of our control. 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 real estate-related depreciation and amortization, 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, preferred stock redemption charges, deal costs, 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 Consolidated Real Estate JVs				Our Share of Unconsolidated Real Estate JVs
	June 30, 2019				June 30, 2019
(In thousands)	Three Months Ended		Six Months Ended		Three Months Ended		Six Months Ended
Net income	$	8,412	$	16,071	$	1,262	$	2,408
Depreciation and amortization	6,744		12,163		973		1,819
Funds from operations	$	15,156	$	28,234	$	2,235	$	4,227

Initial stabilized yield (unlevered)

Initial stabilized yield is calculated as the quotient of the estimated amounts of net operating income at stabilization and 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 June 30, 2019, 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 and technology 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 joint ventures, which are not presented in accordance with, 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, 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, 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 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 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 for the year ended December 31, 2018, 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 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 a non-real estate investment when its fair value declines below its carrying value 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.

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 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 “Tenant Recoveries” below for additional information on our definition of 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 tenant security deposits 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 to Adjusted EBITDA and net debt and preferred stock to Adjusted EBITDA

Net debt to Adjusted EBITDA and net debt and preferred stock to Adjusted EBITDA are non-GAAP financial measures that we believe are useful to investors as supplemental measures in evaluating our balance sheet leverage. Net debt is equal to the sum of total consolidated debt less cash, cash equivalents, and restricted cash. Net debt and preferred stock is equal to the sum of net debt, as discussed above, 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 to net debt and preferred stock, and computes the ratio of each 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, impairment 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 the quotient of net operating income generated by a property and 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 calculated under a new ASU effective January 1, 2018, 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, and 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

(1) Includes 9880 Campus Point Drive, a building we acquired in 2001. The building was occupied through January 2018 and subsequently demolished. The 98,000 RSF project is currently in active development.

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 comprised of 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.

On January 1, 2019, we adopted a new lease accounting standard and, among other practical expedients and policies, we elected the single component accounting policy. As a result of our election of the single component accounting policy, we account for rental revenues and tenant recoveries generated through the leasing of real estate assets that qualify for this policy as a single component, and classify associated revenue in income from rentals in our consolidated statements of operations. Prior to the adoption of the new lease accounting standard, we presented rental revenues and tenant recoveries separately in our consolidated statements of operations. We continue to provide investors with a separate presentation of rental revenues and tenant recoveries in the “Same Property Performance” section of this Supplemental Information because we believe it promotes investors’ understanding of the changes in our operating results. We believe that 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)	6/30/19		3/31/19		12/31/18		9/30/18		6/30/18
Unencumbered net operating income	$	251,397	$	243,191	$	213,285	$	213,107	$	204,843
Encumbered net operating income	16,770		14,150		29,496		28,957		28,283
Total net operating income	$	268,167	$	257,341	$	242,781	$	242,064	$	233,126

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 our 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
	6/30/19	3/31/19	12/31/18	9/30/18	6/30/18
Weighted-average interest rate for capitalization of interest	4.14%	3.96%	4.01%	4.06%	3.92%

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, 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 June 30, 2019, we had Forward Agreements outstanding to sell an aggregate 8.1 million shares of common stock, including 4.4 million shares expiring in June 2020 and 3.7 million shares expiring in July 2020.

We also consider the effect of assumed conversion of our outstanding 7.00% Series D cumulative convertible preferred stock (“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. Our Series D Convertible Preferred Stock is dilutive and assumed to be converted when quarterly and annual basic EPS, funds from operations, or funds from operations, as adjusted, exceed 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 is included when it is 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:
