Notes to Consolidated Financial Statements

1.	Organization and basis of presentation

Alexandria Real Estate Equities, Inc. (NYSE:ARE), an S&P 500 ^® company, is an urban office REIT uniquely focused on collaborative life science and technology campuses in AAA innovation cluster locations. As used in this quarterly report on Form 10‑Q , references to the “Company,” “Alexandria,” “ARE,” “we,” “us,” and “our” refer to Alexandria Real Estate Equities, Inc. and its consolidated subsidiaries. The accompanying unaudited consolidated financial statements include the accounts of Alexandria Real Estate Equities, Inc. and its consolidated subsidiaries. All significant intercompany balances and transactions have been eliminated.

We have prepared the accompanying interim consolidated financial statements in accordance with GAAP and in conformity with the rules and regulations of the SEC. In our opinion, the interim consolidated financial statements presented herein reflect all adjustments, of a normal recurring nature, that are necessary to fairly present the interim consolidated financial statements. The results of operations for the interim period are not necessarily indicative of the results that may be expected for the year ending December 31, 2018 . These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our annual report on Form 10‑K for the year ended December 31, 2017 . Any references to our market capitalization, number or quality of buildings, quality of location, square footage, number of leases, occupancy percentage, and tenants, and any amounts derived from these values in the notes to consolidated financial statements, are outside the scope of our independent registered public accounting firm’s interim review.


2.	Summary of significant accounting policies

Consolidation

On an ongoing basis, as circumstances indicate the need for reconsideration, we evaluate each legal entity that is not wholly owned by us in accordance with the consolidation guidance. Our evaluation considers all of our variable interests, including equity ownership, as well as fees paid to us for our involvement in the management of each partially owned entity. To fall within the scope of the consolidation guidance, an entity must meet both of the following criteria:


•	The entity has a legal structure that has been established to conduct business activities and to hold assets; such entity can be in the form of a partnership, limited liability company, or corporation, among others; and


•	We have a variable interest in the legal entity – i.e., variable interests that are contractual, such as equity ownership, or other financial interests that change with changes in the fair value of the entity’s net assets.

If an entity does not meet both criteria above, we apply other accounting literature, such as the cost or equity method of accounting. If an entity does meet both criteria above, we evaluate such entity for consolidation under either the variable interest model if the legal entity meets any of the following characteristics to qualify as a VIE, or under the voting model for all other legal entities that are not VIEs.

A legal entity is determined to be a VIE if it has any of the following three characteristics:


1)	The entity does not have sufficient equity to finance its activities without additional subordinated financial support;


2)	The entity is established with non-substantive voting rights (i.e., where the entity deprives the majority economic interest holder(s) of voting rights); or


3)	The equity holders, as a group, lack the characteristics of a controlling financial interest. Equity holders meet this criterion if they lack any of the following:


•	The power, through voting rights or similar rights, to direct the activities of the entity that most significantly influence the entity’s economic performance, as evidenced by:


•	Substantive participating rights in day-to-day management of the entity’s activities; or


•	Substantive kick-out rights over the party responsible for significant decisions;


•	The obligation to absorb the entity’s expected losses; or


•	The right to receive the entity’s expected residual returns.


2.	Summary of significant accounting policies (continued)

Once we consider the sufficiency of equity and voting rights of each legal entity, we then evaluate the characteristics of the equity holders’ interests, as a group, to see if they qualify as controlling financial interests. Our real estate joint ventures consist of limited partnerships or limited liability companies. For an entity structured as a limited partnership or a limited liability company, our evaluation of whether the equity holders (equity partners other than us in each of our joint ventures) lack the characteristics of a controlling financial interest includes the evaluation of whether the limited partners or non-managing members (the noncontrolling equity holders) lack both substantive participating rights and substantive kick-out rights, defined as follows:


•	Participating rights provide the noncontrolling equity holders the ability to direct significant financial and operating decisions made in the ordinary course of business that most significantly influence the entity’s economic performance.


•	Kick-out rights allow the noncontrolling equity holders to remove the general partner or managing member without cause.

If we conclude that any of the three characteristics of a VIE are met, including that the equity holders lack the characteristics of a controlling financial interest because they lack both substantive participating rights and substantive kick-out rights, we conclude that the entity is a VIE and evaluate it for consolidation under the variable interest model.

If an entity is determined to be a VIE, we evaluate whether we are the primary beneficiary. The primary beneficiary analysis is a qualitative analysis based on power and benefits. We consolidate a VIE if we have both power and benefits – that is, (i) we have the power to direct the activities of a VIE that most significantly influence the VIE’s economic performance (power), and (ii) we have the obligation to absorb losses of the VIE that could potentially be significant to the VIE, or the right to receive benefits from the VIE that potentially could be significant to the VIE (benefits). We consolidate VIEs whenever we determine that we are the primary beneficiary. Refer to Note 4 – “Consolidated and Unconsolidated Real Estate Joint Ventures” to these unaudited consolidated financial statements for information on specific joint ventures that qualify as VIEs. If we have a variable interest in a VIE but we are not the primary beneficiary, we account for our investment using the equity method of accounting.

Voting model

If a legal entity fails to meet any of the three characteristics of a VIE (due to insufficiency of equity, existence of non-substantive voting rights, or lack of a controlling financial interest), we then evaluate such entity under the voting model. Under the voting model, we consolidate the entity if we determine that we, directly or indirectly, have greater than 50% of the voting shares and that other equity holders do not have substantive participating rights. Refer to Note 4 – “Consolidated and Unconsolidated Real Estate Joint Ventures” to these unaudited consolidated financial statements for further information on our unconsolidated real estate joint ventures that qualify for evaluation under the voting model.

Use of estimates

The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, and equity; the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements; and the amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates.

Investments in real estate

Evaluation of business combination or asset acquisition

We evaluate each acquisition of real estate or in-substance real estate (including equity interests in entities that predominantly hold real estate assets) to determine whether the integrated set of assets and activities acquired meets the definition of a business and need to be accounted as a business combination. An acquisition of an integrated set of assets and activities that does not meet the definition of a business is accounted for as an asset acquisition. If either of the following criteria is met, the integrated set of assets and activities acquired would not qualify as a business:


•	Substantially all of the fair value of the gross assets acquired is concentrated in either a single identifiable asset or a group of similar identifiable assets; or


•	The integrated set of assets and activities is lacking, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs (i.e., revenue generated before and after the transaction).


2.	Summary of significant accounting policies (continued)

An acquired process is considered substantive if:


•	The process includes an organized workforce (or includes an acquired contract that provides access to an organized workforce) that is skilled, knowledgeable, and experienced in performing the process;


•	The process cannot be replaced without significant cost, effort, or delay; or


•	The process is considered unique or scarce.

Generally, we expect that acquisitions of real estate or in-substance real estate will not meet the revised definition of a business because substantially all of the fair value is concentrated in a single identifiable asset or group of similar identifiable assets (i.e., land, buildings, and related intangible assets) or because the acquisition does not include a substantive process in the form of an acquired workforce or an acquired contract that cannot be replaced without significant cost, effort, or delay. When evaluating acquired service or management contracts, we consider the nature of the services performed, the terms of the contract relative to similar arm’s-length contracts, and the availability of comparable vendors in evaluating whether the acquired contract constitutes a substantive process.

Recognition of real estate acquired

For acquisitions of real estate or in-substance real estate that are accounted for as business combinations, we recognize the assets acquired (including the intangible value of acquired above- or below-market leases, acquired in-place leases, tenant relationships, and other intangible assets or liabilities), liabilities assumed, noncontrolling interests, and previously existing ownership interests at fair value as of the acquisition date. Any excess (deficit) of the consideration transferred relative to the fair value of the net assets acquired is accounted for as goodwill (bargain purchase gain). Acquisition costs related to business combinations are expensed as incurred.

Acquisitions of real estate and in-substance real estate that do not meet the definition of a business are accounted for as asset acquisitions. The accounting model for asset acquisitions is similar to the accounting model for business combinations except that the acquisition consideration (including acquisition costs) is allocated to the individual assets acquired and liabilities assumed on a relative fair value basis. As a result, asset acquisitions do not result in the recognition of goodwill or a bargain purchase gain. Additionally, because the accounting model for asset acquisitions is a cost accumulation model, preexisting interests in the acquired assets, if any, are not remeasured to fair value but continue to be accounted for at their historical cost. Direct acquisition costs are capitalized if an asset acquisition is probable. If we determine that an asset acquisition is no longer probable, no new costs are capitalized and all capitalized costs that are not recoverable are expensed.

The relative fair values used to allocate the cost of an asset acquisition are determined by the same methodologies and assumptions we utilize to determine fair value in a business combination.

If a real estate property is acquired with an in-place lease that contains a bargain fixed-rate renewal option for the period beyond the non-cancelable lease term, we evaluate factors, such as the business conditions in the industry in which the lessee operates, the economic conditions in the area in which the property is located, and the ability of the lessee to sublease its space during the renewal term, in order to determine the likelihood that the lessee will renew. When we determine there is reasonable assurance that such bargain renewal option will be exercised, we consider the option in determining the intangible value of such lease and its related amortization period. The value of tangible assets acquired is based upon our estimation of value on an “as if vacant” basis. The value of acquired in-place leases includes the estimated costs during the hypothetical lease-up period and other costs that would have been incurred in the execution of similar leases under the market conditions at the acquisition date of the acquired in-place lease. We assess the fair value of tangible and intangible assets based on numerous factors, including estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors, including the historical operating results, known trends, and market/economic conditions, that may affect the property.

The values allocated to buildings and building improvements, land improvements, tenant improvements, and equipment are depreciated on a straight-line basis using the shorter of the term of the respective ground lease and up to 40 years for buildings and building improvements, an estimated life of up to 20 years for land improvements, the respective lease term for tenant improvements, and the estimated useful life for equipment. The values of acquired above- and below-market leases are amortized over the terms of the related leases and recognized as either increases (for below-market leases) or decreases (for above-market leases) to rental revenue. The values of acquired above- and below-market ground leases are amortized over the terms of the related ground leases and recognized as either increases (for below-market ground leases) or decreases (for above-market ground leases) to rental operating expense. The values of acquired in-place leases are classified in other assets in the accompanying consolidated balance sheets and amortized over the remaining terms of the related leases.


2.	Summary of significant accounting policies (continued)

Capitalized project costs

We capitalize project costs, including pre-construction costs, interest, property taxes, insurance, and other costs directly related and essential to the development, redevelopment, pre-construction, or construction of a project. Capitalization of development, redevelopment, pre-construction, and construction costs is required while activities are ongoing to prepare an asset for its intended use. Fluctuations in our development, redevelopment, pre-construction, and construction activities could result in significant changes to total expenses and net income. Costs incurred after a project is substantially complete and ready for its intended use are expensed as incurred. Should development, redevelopment, pre-construction, or construction activity cease, interest, property taxes, insurance, and certain other costs would no longer be eligible for capitalization and would be expensed as incurred. Expenditures for repairs and maintenance are expensed as incurred.

Real estate sales

A property is classified as held for sale when all of the following criteria for a plan of sale have been met: (i) management, having the authority to approve the action, commits to a plan to sell the property; (ii) the property is available for immediate sale in its present condition, subject only to terms that are usual and customary; (iii) an active program to locate a buyer and other actions required to complete the plan to sell have been initiated; (iv) the sale of the property is probable and is expected to be completed within one year ; (v) the property is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (vi) actions necessary to complete the plan of sale indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Depreciation of assets ceases upon designation of a property as held for sale.

If the disposal of a property represents a strategic shift that has (or will have) a major effect on our operations or financial results, such as (i) a major line of business, (ii) a major geographic area, (iii) a major equity method investment, or (iv) other major parts of an entity, then the operations of the property, including any interest expense directly attributable to it, are classified as discontinued operations in our consolidated statements of income, and amounts for all prior periods presented are reclassified from continuing operations to discontinued operations. The disposal of an individual property generally will not represent a strategic shift and, therefore, will typically not meet the criteria for classification as a discontinued operation.

Impairment of long-lived assets

On a quarterly basis, we review current activities and changes in the business conditions of all of our properties prior to and subsequent to the end of each quarter to determine the existence of any triggering events requiring an impairment analysis. If triggering events are identified, we review an estimate of the future undiscounted cash flows for the properties, including, if necessary, a probability-weighted approach if multiple outcomes are under consideration.

Long-lived assets to be held and used, including our rental properties, CIP, land held for development, and intangibles, are individually evaluated for impairment when conditions exist that may indicate that the carrying amount of a long-lived asset may not be recoverable. The carrying amount of a long-lived asset to be held and used is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. Impairment indicators or triggering events for long-lived assets to be held and used, including our rental properties, CIP, land held for development, and intangibles, are assessed by project and include significant fluctuations in estimated net operating income, occupancy changes, significant near-term lease expirations, current and historical operating and/or cash flow losses, construction costs, estimated completion dates, rental rates, and other market factors. We assess the expected undiscounted cash flows based upon numerous factors, including, but not limited to, construction costs, available market information, current and historical operating results, known trends, current market/economic conditions that may affect the property, and our assumptions about the use of the asset, including, if necessary, a probability-weighted approach if multiple outcomes are under consideration. Upon determination that an impairment has occurred, a write-down is recognized to reduce the carrying amount to its estimated fair value. If an impairment loss is not required to be recognized, the recognition of depreciation is adjusted prospectively, as necessary, to reduce the carrying amount of the real estate to its estimated disposition value over the remaining period that the real estate is expected to be held and used. We may adjust depreciation of properties that are expected to be disposed of or redeveloped prior to the end of their useful lives.

We use the held for sale impairment model for our properties classified as held for sale. The held for sale impairment model is different from the held and used impairment model. Under the held for sale impairment model, an impairment loss is recognized if the carrying amount of the long-lived asset classified as held for sale exceeds its fair value less cost to sell. Because of these two different models, it is possible for a long-lived asset previously classified as held and used to require the recognition of an impairment charge upon classification as held for sale.

International operations

In addition to operating properties in the U.S., we have three operating properties in Canada and one operating property in China. The functional currency for our subsidiaries operating in the U.S. is the U.S. dollar. The functional currencies for our foreign subsidiaries are the local currencies in each respective country. The assets and liabilities of our foreign subsidiaries are translated into U.S. dollars at the exchange rate in effect as of the financial statement date. Income statement accounts of our foreign subsidiaries are translated using the weighted-average exchange rate for the periods presented. Gains or losses resulting from the translation are classified in accumulated other comprehensive income as a separate component of total equity.

Whenever a foreign investment meets the criteria for classification as held for sale, we evaluate the recoverability of the investment under the held for sale impairment model. We may recognize an impairment charge if the carrying amount of the investment exceeds its fair value less cost to sell. In determining an investment’s carrying amount, we consider its net book value and any cumulative unrealized foreign currency translation adjustment related to the investment.

The appropriate amounts of foreign exchange rate gains or losses classified in accumulated other comprehensive income are reclassified to net income when realized upon the sale of our investment or upon the complete or substantially complete liquidation of our investment.

Investments

We hold investments in publicly traded companies and privately held entities primarily involved in the life science and technology industries. As a REIT, we generally limit our ownership percentage in the voting stock of each individual entity to less than 10% .

Prior to January 1, 2018

Prior to the adoption of a new ASU on financial instruments effective January 1, 2018, all of our equity investments in actively traded public companies were considered available-for-sale and were reflected in the accompanying consolidated balance sheets at fair value. Fair value was determined based upon the closing price as of each balance sheet date, with unrealized gains and losses shown as a separate component of other comprehensive income within equity (excluded from net income). The classification of each investment was determined at the time each investment was made, and such determination was reevaluated at each balance sheet date. The cost of each investment sold was determined by the specific identification method, with realized gains or losses classified in other income in the accompanying consolidated statements of operations. Investments in privately held entities were generally accounted for under the cost method when our interest in the entity was so minor that we had virtually no influence over the entity’s operating and financial policies. Investments in privately held entities were accounted for under the equity method unless our interest in the entity was deemed to be so minor that we had virtually no influence over the entity’s operating and financial policies. Under the equity method of accounting, we recognized our investment initially at cost and adjusted the carrying amount of the investment to recognize our share of the earnings or losses of the investee subsequent to the date of our investment.

We periodically assessed our investments in available-for-sale equity securities and privately held companies accounted for under the cost method for other-than-temporary impairment. We monitored each of our investments throughout the year for new developments, including operating results, results of clinical trials, capital-raising events, and merger and acquisition activities. Individual investments were evaluated for impairment when changes in conditions indicated an impairment may exist. The factors that we considered in making these assessments included, but were not limited to, market prices, market conditions, available financing, prospects for favorable or unfavorable clinical trial results, new product initiatives, and new collaborative agreements. If an unrealized loss related to an available-for-sale equity security was determined to be other-than-temporary, such unrealized loss was reclassified from other comprehensive income within equity into earnings. For a cost method investment, if a decline in the fair value of an investment below its carrying value was determined to be other-than-temporary, such investment was written down to its estimated fair value with a charge to earnings. If there were no identified events or changes in circumstances that might have had an adverse effect on our cost method investments, we did not estimate the investment’s fair value.


2.	Summary of significant accounting policies (continued)

Effective January 1, 2018

Beginning on January 1, 2018, under the new ASU, equity investments (except those accounted for under the equity method and those that result in consolidation of the investee) are measured at fair value, with changes in fair value recognized in net income, as follows:

•

Investments in publicly traded companies are classified as investments with readily determinable fair values. These investments are carried at fair value, with changes in fair value recognized through earnings, rather than other comprehensive income within equity. The fair values for our investments in publicly traded companies continue to be determined based on sales prices/quotes available on securities exchanges, or published prices that serve as the basis for current transactions.


•	Investments in privately held entities without readily determinable fair values fall into two categories:


•	Investments in privately held entities that report net asset value per share (“NAV”), such as our privately held investments in limited partnerships, are carried at fair value using NAV as a practical expedient with changes in fair value recognized in net income.


•	Investments in privately held entities that do not report NAV are accounted for using a measurement alternative which allows these investments to be measured at cost, adjusted for observable price changes and impairments, with changes recognized in net income.

For investments in privately held entities that do not report NAV, 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. For these transactions to be considered observable price changes, we evaluate whether the investments have similar rights and obligations including voting rights, distribution preferences, conversion rights, and other factors to the investments we hold.

Investments in privately held entities that do not report NAV will continue to be evaluated on the basis of a qualitative assessment for indicators of impairment, utilizing the same monitoring criteria described above. If such indicators are present, we are required to estimate the investment’s fair value and immediately recognize an impairment loss, without consideration as to whether the impairment is other-than-temporary, in an amount equal to the investment’s carrying value in excess of its estimated fair value.

Investments in privately held entities will continue to be accounted for under the equity method unless our interest in the entity is deemed to be so minor that we have virtually no influence over the entity’s operating and financial policies. Under the equity method of accounting, we continue to recognize our investment initially at cost and adjust the carrying amount of the investment to recognize our share of the earnings or losses of the investee subsequent to the date of our investment.

Initial adoption of new ASU

On January 1, 2018, we recognized the following adjustments upon adoption of the new ASU:


•	For investments in publicly traded companies, reclassification of unrealized gains as of December 31, 2017, aggregating $49.8 million , from accumulated other comprehensive income to retained earnings.


•	For investments in privately held entities without readily determinable fair values that were previously accounted for under the cost method:


•	Adjustment to investments for unrealized gains aggregating $90.8 million related to investments in privately held entities that report NAV, representing the difference between fair value as of December 31, 2017, using NAV as a practical expedient, and the carrying value of the investments as of December 31, 2017, with a corresponding adjustment to retained earnings.

•

No adjustment was required for investments in privately held entities that do not report NAV. The ASU requires a prospective transition approach for investments in privately held entities that do not report NAV. The FASB clarified that it would be difficult for entities to determine the last observable transaction price existing prior to the adoption of this ASU. Therefore, unlike our investments in privately held entities that report NAV that were adjusted to reflect fair values upon adoption of the new ASU, our investments in privately held entities that do not report NAV were not retrospectively adjusted to fair values upon adoption. As such, any initial valuation adjustments made for investments in privately held entities that do not report NAV subsequent to January 1, 2018 as a result of future observable price changes will include recognition of cumulative unrealized gains or losses equal to the difference between the carrying basis of the investment and the observable price at the date of measurement.


2.	Summary of significant accounting policies (continued)

Recognition of rental income and tenant recoveries

Rental revenue from operating leases is recognized on a straight-line basis over the respective lease terms. We classify amounts currently recognized as rental revenue in our consolidated statements of income, and amounts expected to be received in later years as deferred rent in the accompanying consolidated balance sheets. Amounts received currently but recognized as revenue in future years are classified in accounts payable, accrued expenses, and tenant security deposits in the accompanying consolidated balance sheets. We commence recognition of rental revenue at the date the property is ready for its intended use and the tenant takes possession of or controls the physical use of the property.

Rental revenue from direct financing leases is recognized over the respective lease terms using the effective interest rate method. At lease inception, we record an asset within other assets in our consolidated balance sheets, which represents our net investment in the direct financing lease. This initial net investment is determined by aggregating the total future minimum lease payments attributable to the direct financing lease and the estimated residual value of the property less unearned income. Over the lease term, the investment in the direct financing lease is reduced and rental income is recognized as rental revenue in our consolidated statements of income and produces a constant periodic rate of return on the net investment in the direct financing lease.

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

Tenant receivables consist primarily of amounts due for contractual lease payments and tenant recoveries. These tenant receivables are expected to be collected within one year . We may maintain an allowance for estimated losses that may result from the inability of our tenants to make payments required under the terms of the lease and for tenant recoveries due. If a tenant fails to make contractual payments beyond any allowance, we may recognize additional bad debt expense in future periods equal to the amount of uncollectible tenant receivables and deferred rent arising from the straight-lining of rent. As of March 31, 2018 , and December 31, 2017 , no allowance for uncollectible tenant receivables and deferred rent was deemed necessary.

Monitoring tenant credit quality

During the term of each lease, we monitor the credit quality of our tenants by (i) monitoring the credit rating of tenants that are rated by a nationally recognized credit rating agency, (ii) reviewing financial statements of the tenants that are publicly available or that are required to be delivered to us pursuant to the applicable lease, (iii) monitoring news reports regarding our tenants and their respective businesses, and (iv) monitoring the timeliness of lease payments. Our research team is responsible for assessing and monitoring the credit quality of our tenants and any material changes in their credit quality.

Income taxes

We are organized and operate as a REIT pursuant to the Internal Revenue Code (the “Code”). Under the Code, a REIT that distributes at least 90% of its REIT taxable income to its stockholders annually (excluding net capital gains) and meets certain other conditions is not subject to federal income tax on its distributed taxable income, but could be subject to certain federal, foreign, state, and local taxes. We distribute 100% of our taxable income annually; therefore, a provision for federal income taxes is not required. In addition to our REIT returns, we file federal, foreign, state, and local tax returns for our subsidiaries. We file with jurisdictions located in the U.S., Canada, India, China, and other international locations. Our tax returns are subject to routine examination in various jurisdictions for the 2012 through 2016 calendar years.

On December 22, 2017, the U.S. President signed a tax reform bill commonly referred to as the Tax Cuts and Jobs Act into law. The tax reform legislation is a far-reaching and complex revision to the U.S. federal income tax laws with disparate and, in some cases, countervailing effect on different categories of taxpayers and industries. The legislation is unclear in many respects and will require clarification and interpretation by the U.S. Treasury Department and the Internal Revenue Service (“IRS”) in the form of amendments, technical corrections, regulations, or other forms of guidance, any of which could lessen or increase the effect of the legislation on us or our stockholders. The outcome of this legislation on state and local tax authorities, and the response by such authorities, is also unclear. We will continue to monitor changes made to, or as a result of, the federal tax law and its potential effect on us.


2.	Summary of significant accounting policies (continued)

Employee share-based payments

We account for forfeitures of share-based awards granted to employees when they occur. This entity-wide accounting policy election only applies to service conditions; for performance conditions, we continue to assess the probability that such conditions will be achieved. As a result of this election, we recognize expense on share-based awards with the time-based vesting condition without reduction for an estimate of forfeitures. Expenses related to forfeited awards are reversed as forfeitures occur. In addition, all nonforfeitable dividends paid on share-based payment awards are initially recognized in retained earnings and reclassified to compensation cost only if forfeitures of the underlying awards occur.

Recent accounting pronouncements

Lease accounting

Overview related to both lessee and lessor accounting

In February 2016, the FASB issued an ASU that sets 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 ASU is effective for us no later than January 1, 2019, with early adoption permitted. We expect to adopt the new lease accounting standard on January 1, 2019. The ASU requires us to identify lease and nonlease components of a lease agreement. This ASU will govern the recognition of revenue for lease components. Revenue related to nonlease components under our lease agreements will be subject to the new revenue recognition standard, effective upon adoption of the new lease accounting standard. However, in March 2018, the FASB tentatively approved significant changes to the application of this ASU by lessors to lease and nonlease components within lease agreements. See further discussion related to this update and other proposed changes in the “Lessor Accounting” section below.

The lease ASU sets new criteria for determining the classification of finance leases for lessees and sales-type leases for lessors. The criteria to determine if a lease should be accounted for as a finance (sales-type) lease include the following: (i) ownership is transferred from lessor to lessee by the end of the lease term, (ii) an option to purchase is reasonably certain to be exercised, (iii) the lease term is for the major part of the underlying asset’s remaining economic life, (iv) the present value of lease payments exceeds substantially all of the fair value of the underlying asset, and (v) the underlying asset is specialized and is expected to have no alternative use at the end of the lease term. If any of these criteria is met, a lease will be classified as a finance lease by the lessee and as a sales-type lease by the lessor. If none of the criteria are met, a lease will be classified as an operating lease by the lessee, but may still qualify as a direct financing lease or an operating lease for the lessor. The existence of a residual value guarantee by either the lessee or any other third party unrelated to the lessor may qualify the lease as a direct financing lease by the lessor. Otherwise, the lease will be classified as an operating lease by both the lessee and lessor.

The lease ASU requires the use of the modified retrospective transition method and does not allow for a full retrospective approach. However, it provides two options for the application of the modified retrospective transition method:

•

Under the first option, this ASU requires application of the standard to all leases that exist at, or commence after, January 1, 2017 (the beginning of the earliest comparative period presented in the 2019 financial statements), with a cumulative adjustment to the opening balance of retained earnings on January 1, 2017, for the effect of applying the standard at the date of initial application, and restatement of the amounts presented prior to January 1, 2019.


•	Under the second option, an entity may elect a practical expedient package, which allows for the following:


•	An entity need not reassess whether any expired or existing contracts are or contain leases;


•	An entity need not reassess the lease classification for any expired or existing leases; and


•	An entity need not reassess initial direct costs for any existing leases.

This practical expedient package is available as a single election that must be consistently applied to all existing leases at the date of adoption. Lessors that adopt this package are not expected to reassess expired or existing leases at the date of initial application, which is January 1, 2017, under the ASU. This option enables entities to “run off” their existing leases for the remainder of the respective lease terms, which eliminates the need to calculate a cumulative adjustment to the opening balance of retained earnings.


2.	Summary of significant accounting policies (continued)

Recent accounting pronouncements (continued)

Lease accounting (continued)

Furthermore, in March 2018, the FASB directed its staff to issue an ASU that provides an optional transition method to make January 1, 2019, the initial application date of the ASU, rather than January 1, 2017. Consequently, entities that elect both the practical expedient package and the optional transitional method will apply the new lease ASU prospectively to leases commencing or modified after January 1, 2019, and will not be required to apply the disclosures under the new lease ASU to comparative periods.

Under either option above, lessees will be required to recognize a right-of-use asset and a lease liability for all operating leases on the date of the initial application based on the present value of the remaining minimum rental payments that were tracked and disclosed under current accounting standards.

The FASB has also clarified that the lease ASU will require an assessment of whether a land easement meets the definition of a lease under the new lease ASU. An entity with existing land easements that are not accounted for as leases under the current lease accounting standards, however, may elect a practical expedient to exclude those land easements from assessment under the new lease accounting standards. The new lease ASU will be applied to all land easement arrangements entered into or modified on and after the ASU effective date; however, it is expected to have little or no effect on land easements that contain minimal or no consideration.

Lessor accounting

We recognized revenue from our lease agreements aggregating $307.2 million for the three months ended March 31, 2018 . This revenue consisted primarily of rental revenue and tenant recoveries aggregating $234.1 million and $73.2 million , respectively.

Under current accounting standards, we recognize rental revenue from our operating leases on a straight-line basis over the respective lease terms. We commence recognition of rental revenue at the date the property is ready for its intended use and the tenant takes possession of or controls the physical use of the property. We recognize rental revenue from direct financing leases over the lease term using the effective interest rate method.

Under current accounting standards, tenant recoveries related to payments of real estate taxes, insurance, utilities, repairs and maintenance, common area expenses, and other operating expenses are considered lease components. We recognize these tenant recoveries as revenue when services are rendered in an amount equal to the related operating expenses incurred that are recoverable under the terms of the applicable lease. Under the new lease ASU, tenant recoveries for utilities, repairs and maintenance, and common area expenses are expected to primarily be categorized as nonlease components. Tenant recoveries for taxes and insurance are expected to be neither lease nor nonlease components under the lease ASU but instead will be considered additional lease revenue to be recognized by the lessor and classified within rental income in our consolidated statements of income.

Under the lease ASU, each lease agreement will be evaluated to identify the lease components and nonlease components at lease inception. The total consideration in the lease agreement will be allocated to the lease and nonlease components based on their relative standalone selling prices. Lessors will continue to recognize the lease revenue component using an approach that is substantially equivalent to existing guidance for operating leases (straight-line basis). Sale-type and direct financing leases will be accounted for as financing transactions with the lease payments being allocated to principal and interest utilizing the effective interest rate method.

In March 2018, the FASB directed its staff to issue an ASU to allow lessors to elect, as a practical expedient, not to allocate the total consideration to lease and nonlease components based on their relative standalone selling prices. If adopted, this single-lease component practical expedient will allow lessors to elect a combined single-lease component presentation if (i) the timing and pattern of transfer of the lease component and the nonlease component(s) associated with it are the same, and (ii) the lease component would be classified as an operating lease if it were accounted for separately. Nonlease components that do not meet the criteria of this practical expedient will be accounted for under the new revenue recognition ASU. The Board also decided to require lessors to account for a combined component that meets these two criteria under the new revenue recognition ASU if the nonlease component is the predominant component. If the nonlease component is not the predominant component, entities will be able to account for the combined component as an operating lease in accordance with the new lease ASU.


2.	Summary of significant accounting policies (continued)

Recent accounting pronouncements (continued)

Lease accounting (continued)

If we elect the single-lease component practical expedient mentioned above, tenant recoveries that qualify for this expedient will be presented in rental revenue as a single-lease component and accounted for under the new lease ASU, primarily as variable consideration. Tenant recoveries that do not qualify for the single-lease component practical expedient and are considered nonlease components will be accounted for under the new revenue recognition ASU upon adoption of the new lease ASU.

Costs to execute leases

The new ASU will require that lessors and lessees capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease (e.g. commissions paid to leasing brokers). Under this ASU, allocated payroll costs and legal costs incurred as part of the leasing process prior to the execution of a lease will no longer qualify for classification as initial direct costs but will instead be expensed as incurred. During the three months ended March 31, 2018 , we capitalized $4.2 million of such costs. Under the new lease ASU, these costs will be expensed as incurred. We will have the option, under the practical expedient package provided by the lease ASU, to continue to amortize previously capitalized initial direct costs incurred prior to the adoption of the ASU.

Lessee accounting

Under the new lease ASU, lessees are required to apply a dual approach by classifying leases as either finance or operating leases based on the principle of whether the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, which corresponds to a similar evaluation performed by lessors. In addition to this classification, a lessee is also required to recognize a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification, whereas a lessor is not required to recognize a right-of-use asset and a lease liability for any operating leases. Leases with a lease term of 12 months or less will be accounted for in a manner similar to existing guidance for operating leases (straight-line basis).

The ASU requires the recognition of a right-of-use asset and a related liability to account for our future obligations under our ground and office lease arrangements for which we are the lessee. At the date of initial application, depending on the practical expedients we elect as discussed above, we will be required to recognize a lease liability measured based on the present value of the remaining lease payments. The right-of-use asset will be equal to the corresponding lease liability, adjusted for initial direct leasing cost and any other consideration exchanged with the landlord prior to the commencement of the lease.

As of March 31, 2018 , the remaining contractual payments under our ground and office lease agreements for which we are the lessee aggregated $590.7 million , and the estimated present value of these payments is in the range from $170.0 million to $230.0 million . This estimated present value range is based on a weighted average remaining lease term of 48 years and within a one-percent range of the current weighted average incremental borrowing rate of 5.96% . The actual lease liability and right-of-use asset to be recognized upon adoption of the new lease ASU will vary depending on changes to our incremental borrowing rate and the practical expedients we elect as discussed above.

All of our existing ground and office leases for which we are the lessee are currently classified as operating leases. Under the practical expedient package provided by the lease ASU, we will have the option to continue to classify these leases as operating leases upon adoption of the lease ASU. We are still evaluating the effect to our consolidated financial statements from the initial recognition of each lease asset and liability upon adoption, and the pattern of recognition of ground lease expense subsequent to adoption.

Allowance for credit losses

In June 2016, the FASB issued an ASU that changes the impairment model for most financial instruments by requiring companies to recognize an allowance for expected losses, rather than incurred losses as required currently by the other-than-temporary impairment model. The ASU will apply to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities, net investments in leases, and off-balance-sheet credit exposures (e.g., loan commitments). The ASU is effective for reporting periods beginning after December 15, 2019, with early adoption permitted, and will be applied as a cumulative adjustment to retained earnings as of the effective date. We are currently assessing the potential effect the adoption of this ASU will have on our consolidated financial statements.

Revenue Recognition

Recognition of revenue arising from contracts with customers

On January 1, 2018, we adopted an ASU on revenue recognition that requires a new model for recognition of revenue arising from contracts with customers, as well as recognition of gains and losses from the transfer of nonfinancial assets arising from contracts with noncustomers. A customer is distinguished from a noncustomer by the nature of the goods or services that are transferred. Customers are provided with goods or services that are generated by a company’s ordinary output activities, whereas noncustomers are provided with nonfinancial assets that are outside of a company’s ordinary output activities.

The core principle underlying the ASU on recognition of revenue arising from contracts with customers is that an entity must recognize revenue to represent the transfer of goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in such exchange. This requires entities to identify contractual performance obligations and determine whether revenue should be recognized at a point in time or over time, based on when control of goods and services transfers to a customer. The ASU requires the use of a new five-step model to recognize revenue from customer contracts. The five-step model requires that we (i) identify the contract with the customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, including variable consideration to the extent that it is probable that a significant future reversal will not occur, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) we satisfy the performance obligation.

An entity is also required to determine if it controls the goods or services prior to the transfer to the customer in order to determine if it should account for the arrangement as a principal or agent. Principal arrangements, where the entity controls the goods or services provided, results in the recognition of the gross amount of consideration expected in the exchange. Agent arrangements, where the entity simply arranges but does not control the goods or services being transferred to the customer, results in the recognition of the net amount the entity is entitled to retain in the exchange. Upon adoption of the new lease ASU in 2019, we will be required to classify our tenant recoveries into lease and nonlease components, whereby the nonlease components would be subject to the ASU on recognition of revenue arising from contracts with customers. However, if we elect a practical expedient as discussed in “Lessor Accounting ” within the “Lease Accounting” section above, tenant recoveries for goods and services that are categorized as nonlease components but which have the same timing and pattern of transfer as the related lease component may (subject to the predominance test) be accounted for under the new lease ASU. Tenant recoveries that do not qualify for the practical expedient will be accounted for under the ASU on recognition of revenue arising from contracts with customers upon adoption of the new lease ASU. Property services categorized as nonlease components that are reimbursed by our tenants may need to be presented on a net basis if it is determined that we hold an agent arrangement.

Entities had options to transition to the ASU on recognition of revenue arising from contracts with customers using either the full retrospective or the modified retrospective method. We adopted this ASU using the modified retrospective method, which requires a cumulative adjustment for effects of applying the new standard to periods prior to 2018 to be recorded to retained earnings as of January 1, 2018. We also elected to apply this ASU only to contracts not completed as of January 1, 2018. For all contracts within the scope of this ASU that were not completed as of January 1, 2018, we evaluated the revenue recognition under accounting standards in effect prior to January 1, 2018, and under the new ASU, and determined that amounts recognized and the pattern of revenue recognition were consistent. Therefore, the adoption of the ASU on recognition of revenue arising from contracts with customers did not result in an adjustment to our retained earnings on January 1, 2018.

Recognition of revenue arising from contracts with customers (continued)

The table below provides the detail of our consolidated revenue for the three months ended March 31, 2018 , by (i) revenues that are subject to the ASU on recognition of revenue arising from contracts with customers, and (ii) revenues subject to other accounting standards (in thousands):



	Three Months Ended March 31, 2018
	Subject to the ASU on Recognition of Revenue Arising from Contracts with Customers		Subject to Other Accounting Guidance		Consolidated
Rental revenues	$	10,433	$	234,052	$	244,485
Tenant recoveries	—		73,170		73,170
Other income	2,020		464		2,484
Total revenue	$	12,453	$	307,686	$	320,139

Rental revenues, subject to the new revenue recognition ASU, aggregating $10.4 million for the three months ended March 31, 2018 , consist primarily of parking revenues. Parking revenues consist primarily of short term rental revenues that are not considered lease revenue. Under the previous accounting standards, we recognized parking and other revenue when the amounts were fixed or determinable, collectibility was reasonably assured, and services were rendered. Under the new ASU, the recognition of such revenue occurs when the services are provided and the performance obligations are satisfied. Parking services are normally provided at a point in time; therefore, revenue recognition under the new ASU is substantially similar to the recognition pattern under accounting standards that were in effect prior to January 1, 2018.

Other income, subject to the new revenue recognition ASU, aggregating $2.0 million for the three months ended March 31, 2018 , consists primarily of construction management fees. We earn construction management fees for the day-to-day management of third-party construction projects. Construction management services represent a series of services that are substantially the same and that can be combined into a single performance obligation. Under the previous accounting guidance, we recognized construction management fees using the percentage of completion method. Under the new ASU, we recognize construction management fees using the output method, which is substantially similar to the percentage of completion method used under the guidance in effect prior to January 1, 2018.

In addition to the analysis above, we evaluated the following qualitative and quantitative disclosure requirements outlined in this ASU during the three months ended March 31, 2018 , as follows:


•	Prior to the adoption of this ASU, we did not have material contract assets and contract liabilities related to contracts with customers subject to the ASU on recognition of revenue arising from contracts with customers and no additional contract assets or contract liabilities were necessary subsequent to adoption on January 1, 2018.


•	Parking and construction management services subjected to the ASU on recognition of revenue arising from contracts with customers do not normally create obligations for returns, refunds, warranties, and other similar obligations. Therefore, no corresponding disclosures were necessary.

Recognition of revenue arising from contracts with noncustomers

On January 1, 2018, we also adopted a new ASU on the derecognition of nonfinancial assets in transactions, including real estate sales, with noncustomers. Our ordinary output activities consist of the leasing of space to our tenants in our operating properties, not the sales of real estate. Therefore, sales of real estate qualify as contracts with noncustomers and are subject to this new ASU.

The new ASU on the derecognition of nonfinancial assets requires entities to apply certain recognition and measurement principles consistent with the new ASU on recognition of revenue arising from contracts with customers. The derecognition model is based on the transfer of control. If a real estate sale contract includes ongoing involvement by the seller with the property, the seller must evaluate each promised good or service under the contract to determine whether it represents a separate performance obligation, constitutes a guarantee, or prevents the transfer of control. If a good or service is considered a separate performance obligation, an allocated portion of the transaction price should be recognized as revenue as the entity transfers the related good or service to the buyer.

The recognition of gain or loss on the sale of a partial interest also depends on whether the seller retains a controlling or noncontrolling interest. Under the new standards, a partial sale of real estate in which the seller retains a controlling interest will result in the seller’s continuing to reflect the asset at its current book value, recording a noncontrolling interest for the book value of the partial interest sold, and recognizing additional paid-in capital for the difference between the consideration received and the partial interest at book value, consistent with the current accounting standards. Conversely, a partial sale of real estate in which a seller retains a noncontrolling interest will result in the recognition by the seller of a gain or loss as if 100% of the real estate was sold.

We adopted the new ASU on the derecognition of nonfinancial assets using the modified retrospective method, the same transition method used to adopt the ASU on recognition of revenue arising from contracts with customers. We also elected to apply this ASU on the derecognition of nonfinancial assets only to contracts not completed as of January 1, 2018. We had no contracts with noncustomers that were not completed as of January 1, 2018; therefore, the adoption of the ASU on the derecognition of nonfinancial assets had no effect on our consolidated financial statements.

During the three months ended March 31, 2018 , we did complete any partial or full sale of real estate assets.


2.	Summary of significant accounting policies (continued)

Joint venture distributions

On January 1, 2018, we adopted an ASU that provides guidance on the classification in the statement of cash flows of cash distributions received from equity method investments, including unconsolidated joint ventures. The ASU provides two approaches to determine the classification of cash distributions received from equity method investees: (i) the “cumulative earnings” approach, under which distributions up to the amount of cumulative equity in earnings recognized are classified as cash inflows from operating activities, and those in excess of that amount are classified as cash inflows from investing activities, and (ii) the “nature of the distribution” approach, under which distributions are classified based on the nature of the underlying activity that generated cash distributions. An entity could elect either the “cumulative earnings” or the “nature of the distribution” approach. If the “nature of the distribution” approach is elected and the entity lacks the information necessary to apply it in the future, that entity will have to apply the “cumulative earnings” approach as an accounting change on a retrospective basis. We adopted this ASU using the “nature of the distribution” approach and applied it retrospectively, as required by the ASU. We previously presented distributions from our equity method investees utilizing the “nature of the distribution” approach; therefore, the adoption of this ASU had no effect on our consolidated financial statements.

Restricted cash

On January 1, 2018, we adopted an ASU that requires entities to include restricted cash with cash and cash equivalents when reconciling the beginning of period and end of period total amounts shown in the statement of cash flows. The ASU requires disclosure of a reconciliation between the balance sheet and the statement of cash flows when the balance sheet includes more than one line item for cash, cash equivalents, restricted cash, and restricted cash equivalents. An entity with material restricted cash and restricted cash equivalents balances is required to disclose the nature of the restrictions. The ASU required a retrospective application to all periods presented. Subsequent to the adoption of this ASU, restricted cash balances are included with cash and cash equivalents balances as of the beginning and ending of each period presented in our consolidated statements of cash flows; separate line items reconciling changes in restricted cash balances to the changes in cash and cash equivalents are no longer presented within the operating, investing, and financing sections of our consolidated statements of cash flows.

Hedge accounting

On January 1, 2018, we adopted an ASU that simplifies hedge accounting. The ASU is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The purpose of this updated ASU is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. For cash flow hedges that are highly effective, the new standard requires all changes (effective and ineffective components) in the fair value of the hedging instrument to be recorded in other comprehensive income within equity and to be reclassified into earnings only when the hedged item affects earnings.

Prior to the adoption of this ASU, a quantitative assessment was made on an ongoing basis to determine whether a hedge is highly effective in offsetting changes in cash flows associated with the hedged item. Previously applied hedge accounting guidance required hedge ineffectiveness to be recognized in earnings. Under the new ASU, an entity is still required to perform an initial quantitative test. However, the new standard allows an entity to elect to subsequently perform only a qualitative assessment, unless facts and circumstances change. We made this election upon adoption of the new ASU on January 1, 2018.

For cash flow hedges in existence at the date of adoption, an entity is required to apply a cumulative-effect adjustment for previously recognized ineffectiveness from retained earnings to accumulated other comprehensive income as of the beginning of the fiscal year when an entity adopts the amendments in this ASU.

We utilize interest rate hedge agreements to hedge a portion of our exposure to variable interest rates primarily associated with borrowings based on LIBOR. As a result, all of our interest rate hedge agreements are designated as cash flow hedges. We performed an analysis of all our cash flow hedges existing on January 1, 2018, and determined that all hedges had been highly effective since their inception; therefore, no cumulative-effect adjustment of previously recognized ineffectiveness from retained earnings to accumulated other comprehensive income was needed. During the three months ended March 31, 2018 and 2017 , we did not have any hedge ineffectiveness related to our interest rate hedge agreements. The adoption of this ASU had no effect on our financial statements on January 1, 2018, or the three months ended March 31, 2018.


3.	Investments in real estate

Our consolidated investments in real estate consisted of the following as of March 31, 2018 , and December 31, 2017 (in thousands):

Acquisitions

Our real estate asset acquisitions during the three months ended March 31, 2018 , consisted of the following (dollars in thousands):

We evaluated each of the transactions detailed below to determine whether the integrated set of assets and activities acquired met the definition of a business. Acquisitions that do not meet the definition of a business are accounted for as asset acquisitions. An integrated set of assets and activities does not qualify as a business if substantially all of the fair value of the gross assets is concentrated in either a single identifiable asset or a group of similar identifiable assets, or if the acquired assets do not include a substantive process.

We evaluated each of the completed acquisitions and determined that substantially all of the fair value related to each acquisition is concentrated in a single identifiable asset or a group of similar identifiable assets, or is a land parcel with no operations. Accordingly, each transaction did not meet the definition of a business and consequently was accounted for as an asset acquisition. In each of these transactions, we allocated the total consideration for each acquisition to the individual assets and liabilities acquired on a relative fair value basis.

Mission Bay/SoMa, San Francisco

1655 and 1725 Third Street

In March 2018, we acquired a 10% interest in a real estate joint venture with Uber Technologies, Inc. (“Uber”) and the Golden State Warriors in 1655 and 1725 Third Street, located in our Mission Bay/SoMa submarket. The joint venture is developing two buildings aggregating 593,765 RSF that are integrated within the new Golden State Warriors complex under development. The buildings are 100% leased to Uber. At the closing of the joint venture agreement, we contributed equity totaling $32.0 million .

The building is an expansion of the Alexandria Technology Center ^® – Gaithersburg II campus. We are redeveloping 58,186 RSF from existing office space into office/laboratory space. Refer to Note 4 – “Consolidated and Unconsolidated Real Estate Joint Ventures” to these unaudited consolidated financial statements for additional information.

Sales of real estate assets

In January 2017, we completed the sale of a vacant property at 6146 Nancy Ridge Drive located in our Sorrento Mesa submarket of San Diego for a purchase price of $3.0 million and recognized a gain of $270 thousand .


4.	Consolidated and unconsolidated real estate joint ventures

From time to time we enter into joint venture agreements through which we own a partial interest in real estate entities that own, develop and operate real estate properties. As of March 31, 2018 , we had the following properties that were held by our real estate joint ventures:

(2)	Represents our ownership interest; our voting interest is limited to 50%.


(3)	Joint venture with a distinguished retail real estate developer for the development of a 90,000 RSF retail shopping center.

Our consolidation guidance is fully described under the “Consolidation” section within Note 2 – “Summary of Significant Accounting Policies” to these unaudited consolidated financial statements. This guidance is highly technical, but its framework is primarily based on the controlling financial interests and benefits of the joint ventures. We generally consolidate a joint venture that is a legal entity that we control (i.e., we have the power to direct the activities of the joint venture that most significantly affect its economic performance) through contractual rights, regardless of our ownership interest, and where we determine that we have benefits through the allocation of earnings or losses and fees paid to us that could be significant to the joint venture (VIE model). We also generally consolidate joint ventures when we have a controlling financial interest through voting rights and where our voting interest is greater than 50% (Voting model). Voting interest differs from ownership interest for some joint ventures. We account for joint ventures that do not meet the consolidation criteria under the equity method of accounting, recognizing our share of income and losses. The table below shows our categorization of our existing joint ventures under the consolidation framework:



Property	Consolidation Model	Voting Interest	Consolidation Analysis	Conclusion

225 Binney Street	VIE model	Not applicable under VIE model	We have control, and benefits that can be significant to the joint venture, therefore we are the primary beneficiary of each VIE	Consolidated

Noncontrolling interests’ share of equity	527,509		520,977
Total liabilities and equity	$	1,166,858	$	1,157,338

In determining whether to aggregate the balance sheet information of our consolidated VIEs, we considered the similarity of each VIE, including the primary purpose of these entities to own, manage, operate, and lease real estate properties owned by the VIEs, and the similar nature of our involvement in each VIE as a managing member. Due to the similarity of the characteristics, we present the balance sheet information of these entities on an aggregated basis. For each of our consolidated VIEs, none of its assets have restrictions that limit their use to settle specific obligations of the VIE. There are no creditors or other partners of our consolidated VIEs that have recourse to our general credit. Our maximum exposure to all our VIEs is limited to our variable interests in each VIE.

Unconsolidated real estate joint ventures

As of March 31, 2018 , our investments in unconsolidated real estate joint ventures accounted for under the equity method of accounting presented in our consolidated balance sheet aggregated $169.9 million , which consists of the following (in thousands):

6.	Investments

We hold investments in publicly traded companies and privately held entities primarily involved in the life science and technology industries. On January 1, 2018, we adopted a new ASU on financial instruments that prospectively changed how we recognize, measure, present, and disclose these investments.

Key differences between prior accounting standards and the new ASU

Prior to January 1, 2018


•	Investments in publicly traded companies were reflected at fair value in the accompanying balance sheet, with changes in fair value recognized in other comprehensive income classified in accumulated other comprehensive income within equity.


•	Investments in privately held entities were accounted for under the cost method of accounting.


•	Gains or losses were recognized in net income upon the sale of an investment.

•

Investments in privately held entities required accounting under the equity method unless our interest in the entity was deemed to be so minor that we had virtually no influence over the entity’s operating and financial policies. Under the equity method of accounting, we recognized our investment initially at cost and adjusted the carrying amount of the investment to recognize our share of the earnings or losses of the investee subsequent to the date of our investment. We had no investments accounted for under the equity method as of December 31, 2017.


•	Investments were evaluated for impairment, with other-than-temporary impairments recognized in net income.

Effective January 1, 2018


•	Investments in publicly traded companies are reflected at fair value in the accompanying balance sheet, with changes in fair value recognized in net income.


•	Investments in privately held entities without readily determinable fair values previously accounted for under the cost method are accounted for as follows:


•	Investments in privately held entities that report NAV are reflected at fair value using NAV as a practical expedient, with changes in fair value recognized in net income.


•	Investments in privately held entities that do not report NAV are carried at cost, adjusted for observable price changes and impairments, with changes recognized in net income.


•	One time adjustments recognized on January 1, 2018:


•	For investments in publicly traded companies, reclassification of cumulative net unrealized gain as of December 31, 2017, aggregating $49.8 million , from accumulated other comprehensive income to retained earnings.


•	For investments in privately held entities without readily determinable fair values that were previously accounted for under the cost method:

•

Adjustment to investments for cumulative unrealized gains related to investments in privately held entities that report NAV, representing the difference between fair value as of December 31, 2017, using NAV as a practical expedient, and the carrying value of the investments as of December 31, 2017, previously accounted for under the cost method, aggregating $90.8 million , with a corresponding adjustment to retained earnings.

•

Investments in privately held entities will continue to require accounting under the equity method unless our interest in the entity is deemed to be so minor that we have virtually no influence over the entity’s operating and financial policies. Under the equity method of accounting, we recognize our investment initially at cost and adjust the carrying amount of the investment to recognize our share of the earnings or losses of the investee subsequent to the date of our investment. We had no investments accounted for under the equity method as of March 31, 2018.

Changes in fair value for investments in publicly traded companies and investments in privately held entities that report NAV, and observable price changes for investments in privately held entities that do not report NAV, are recognized as unrealized gains or losses and classified as investment income in our consolidated statements of income. For further information regarding the new ASU, refer to the “Investments” section within Note 2 – “Summary of Significant Accounting Policies” to these unaudited consolidated financial statements.

Cumulative unrealized gains on investments in privately held entities that do not report NAV aggregating $11.0 million as of March 31, 2018 , consisted of upward adjustments representing unrealized gains of $11.4 million and downward adjustments representing unrealized losses of $353 thousand recognized in net income during the three months ended March 31, 2018 . We adjusted our investments in privately held entities that do not report NAV based on observable price changes from subsequent equity offerings. The subsequent equity offerings observed were for similar securities to those we hold as the securities had similar (i) voting rights, (ii) distribution preferences, and (iii) conversion rights.

Investments in privately held entities that report NAV

Investments in privately held entities that report NAV consist primarily of investments in limited partnerships that invest in life science and technology entities. We are committed to funding approximately $175.7 million for all investments over the next several years, primarily consisting of $173.0 million related to these investments.

These investments are not redeemable by us, but we normally receive distributions from these investments throughout their term. Our investments in privately held entities that report NAV generally have an expected initial term in excess of 10 years. Weighted average remaining term during which these investments are expected to be liquidated was 4.6 years as of March 31, 2018 .

8.	Fair value measurements

We provide fair value information about all financial instruments for which it is practicable to estimate fair value. We measure and disclose the estimated fair value of financial assets and liabilities utilizing a fair value hierarchy that distinguishes between data obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions. This hierarchy consists of three broad levels, as follows: (i) quoted prices in active markets for identical assets or liabilities, (ii) significant other observable inputs, and (iii) significant unobservable inputs. Significant other observable inputs can include quoted prices for similar assets or liabilities in active markets, as well as inputs that are observable for the asset or liability, such as interest rates, foreign exchange rates, and yield curves. Significant unobservable inputs are typically based on an entity’s own assumptions, since there is little, if any, related market activity. In instances in which the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level of input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. There were no transfers between the levels in the fair value hierarchy during the three months ended March 31, 2018 and 2017 .

The following tables set forth the assets and liabilities that we measure at fair value on a recurring basis by level within the fair value hierarchy as of March 31, 2018 and December 31, 2017 (in thousands):



			March 31, 2018
Description	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Our investments in publicly traded companies have been recognized at fair value. Investments in privately held entities that report NAV, which are carried at their reported NAV as a practical expedient to fair value, are excluded from the fair value hierarchy above as required by the fair value standards. Investments in privately held entities that do not report NAV, measured at cost less impairments, adjusted for observable price changes, which do not necessarily represent fair value, are also excluded from the fair value hierarchy above. Refer to Note 6 – “Investments” to these unaudited consolidated financial statements for further details.

Our interest rate hedge agreements have been recognized at fair value. Refer to Note 10 – “Interest Rate Hedge Agreements” to these unaudited consolidated financial statements for further details. The carrying values of cash and cash equivalents, restricted cash, tenant receivables, other assets, accounts payable, accrued expenses, and tenant security deposits approximate fair value.


8.	Fair value measurements (continued)

The fair values of our secured notes payable, unsecured senior notes payable, $1.65 billion unsecured senior line of credit, and unsecured senior bank term loans were estimated using widely accepted valuation techniques, including discounted cash flow analyses using significant other observable inputs such as available market information on discount and borrowing rates with similar terms, maturities, and credit ratings. Because the valuations of our financial instruments are based on these types of estimates, the actual fair value of our financial instruments may differ materially if our estimates do not prove to be accurate. Additionally, the use of different market assumptions or estimation methods may have a material effect on the estimated fair value amounts.

As of March 31, 2018 , and December 31, 2017 , the book and estimated fair values of our investments in privately held entities that report NAV, secured notes payable, unsecured senior notes payable, unsecured senior line of credit, and unsecured senior bank term loans were as follows (in thousands):



	March 31, 2018				December 31, 2017

3.45% Unsecured senior notes payable due in 2025

In November 2017, we completed a $600.0 million public offering of our unsecured senior notes payable due on April 30, 2025 , at a stated interest rate of 3.45% . We used the net proceeds, after discounts and issuance costs, of 593.5 million to repay two secured notes payable aggregating $389.8 million and for general corporate purposes including the reduction of the outstanding balance on our $1.65 billion unsecured senior line of credit.

3.95% Unsecured senior notes payable due in 2028

In March 2017, we completed a $425.0 million public offering of our unsecured senior notes payable due on January 15, 2028 , at a stated interest rate of 3.95% . We used the net proceeds, after discounts and issuance costs, of $420.5 million to repay outstanding borrowings under our $1.65 billion unsecured senior line of credit.

Repayment of unsecured senior bank term loan

During the three months ended March 31, 2017, we completed a partial principal repayment of $200 million of our 2019 Unsecured Senior Bank Term Loan, reducing the total outstanding balance from $400 million to $200 million , and recognized a loss on early extinguishment of debt of $670 thousand related to the write-off of unamortized loan fees.

Interest expense

The following table summarizes interest expense for the three months ended March 31, 2018 and 2017 (in thousands):



	Three Months Ended March 31,

Gross interest	$	50,275		$	42,948
Capitalized interest	(13,360		)	(13,164		)
Interest expense	$	36,915		$	29,784


10.	Interest rate hedge agreements

We use interest rate derivatives to hedge the variable cash flows associated with certain of our existing LIBOR-based variable-rate debt, including our $1.65 billion unsecured senior line of credit, unsecured senior bank term loans, and secured notes payable, and to manage our exposure to interest rate volatility.

Changes in fair value, including accrued interest and adjustments for non-performance risk, on our interest rate hedge agreements that are designated and that qualify as cash flow hedges are classified in accumulated other comprehensive income. Amounts classified in accumulated other comprehensive income are subsequently reclassified into earnings in the period during which the hedged transactions affect earnings. During the next 12 months, we expect to reclassify approximately $5.8 million from accumulated other comprehensive income to earnings as a decrease of interest expense. As of March 31, 2018 , and December 31, 2017 , the fair values of our interest rate hedge agreements aggregating an asset balance were classified in other assets, and the fair values of our interest rate hedge agreements aggregating a liability balance were classified in accounts payable, accrued expenses, and tenant security deposits, based upon their respective fair values, without any offsetting pursuant to master netting agreements. Refer to Note 8 – “Fair Value Measurements” to these unaudited consolidated financial statements for further details. Under our interest rate hedge agreements, we have no collateral posting requirements.

We have agreements with certain of our derivative counterparties that contain a provision wherein we could be declared in default on our derivative obligations (i) if repayment of the underlying indebtedness is accelerated by the lender due to our default on the indebtedness, or (ii) if we default on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender. If we had breached any of these provisions, we could have been required to settle our obligations under the agreements at their termination value. As of March 31, 2018 , none of our interest rate hedge agreements were in a liability position, so there were no associated termination obligations.

We had the following outstanding interest rate hedge agreements that were designated as cash flow hedges of interest rate risk as of March 31, 2018 (dollars in thousands):



		Number of Contracts	Weighted-Average Interest Pay Rate ⁽¹⁾	Fair Value as of 3/31/18		Notional Amount in Effect as of

Total	$	783,986	$	763,832

Some of our properties may contain asbestos, which, under certain conditions, requires remediation. Although we believe that the asbestos is appropriately contained in accordance with environmental regulations, our practice is to remediate the asbestos upon the development or redevelopment of the affected property. We recognize a liability for the fair value of a conditional asset retirement obligation (including asbestos) when the fair value of the liability can be reasonably estimated. For certain properties we do not recognize an asset retirement obligation when there is an indeterminate settlement date for the obligation because the period in which we may remediate the obligation may not be estimated with any level of precision to provide for a meaningful estimate of the retirement obligation.


12.	Earnings per share

In January 2018, we entered into forward equity sales agreements to sell an aggregate of 6.9 million shares of our common stock (including the exercise of underwriters’ option) at a public offering price of $123.50 per share, before underwriting discounts. In March 2018, we settled 843,600 shares from our forward equity sales agreements and received proceeds of $100.2 million , net of underwriting discounts and adjustments provided in the forward equity sales agreements. We expect to receive proceeds of $713.7 million upon settlement of the remaining outstanding forward equity sales agreements, to be further adjusted as provided in the sales agreements. The remaining forward equity sales agreements expire no later than April 2019, and we expect to settle these agreements in 2018.

In March 2017, we entered into agreements to sell an aggregate of 6.9 million shares of our common stock, which consisted of an initial issuance of 2.1 million shares and 4.8 million shares subject to forward equity sales agreements, at a public offering price of $108.55 per share less issuance costs, underwriters’ discount, and further adjustments as provided in the sales agreements. We issued the initial 2.1 million shares at closing in March 2017 for net proceeds, after underwriters’ discount and issuance costs, of $217.8 million and settled the forward equity sales agreements on the remaining 4.8 million shares of common stock in December 2017 for net proceeds, after underwriters’ discount and issuance costs, of $484.6 million .

To account for the forward equity sales agreements, we considered the accounting guidance governing financial instruments and derivatives and concluded that our forward equity sales agreements were not liabilities as they did not embody obligations to repurchase our shares nor did they embody obligations to issue a variable number of shares for which the monetary value was predominantly fixed, varying with something other than the fair value of our shares, or varying inversely in relation to our shares. We then evaluated whether the agreements met the derivatives and hedging guidance scope exception to be accounted for as equity instruments and concluded that the agreements can be classified as equity contracts based on the following assessment: (i) none of the agreements’ exercise contingencies were based on observable markets or indices besides those related to the market for our own stock price and operations; and (ii) none of the settlement provisions precluded the agreements from being indexed to our own stock.


12.	Earnings per share (continued)

We also considered the potential dilution resulting from the forward equity sales agreements on the EPS calculations. At inception, the agreements do not have an effect on the computation of basic EPS as no shares are delivered until settlement. We use the treasury stock method to determine the dilution resulting from the forward equity sales agreements during the period of time prior to settlement. The common shares issued upon the settlement of the forward equity sales agreements, weighted for the period these

common shares were outstanding, are included in the denominator of basic EPS. The number of weighted-average shares outstanding – diluted used in the computation of EPS for the three months ended March 31, 2018 , includes the effect from the assumed issuance of common stock pursuant to the settlement of forward equity sales agreements outstanding during the period at the contractual price, less the assumed repurchase of common shares at the average market price using the net proceeds, adjusted as provided for in the forward equity sales agreements. The effect to our weighted-average shares – diluted for the three months ended March 31, 2018 , was 270 thousand weighted-average incremental shares. For the three months ended March 31, 2017 , the effect to our weighted-average shares – diluted from similar forward equity sales transactions was 53 thousand weighted-average incremental shares. The common shares issued upon the settlement of the forward equity sales agreements in March 2018 aggregating 843,600 , weighted for the period these common shares were outstanding, were included in the denominator of basic EPS.

For purposes of calculating diluted EPS, we did not assume conversion of our 7.00% Series D cumulative convertible preferred stock (“Series D Convertible Preferred Stock”) for the three months ended March 31, 2018 and 2017 , since the result was antidilutive to EPS attributable to Alexandria Real Estate Equities, Inc.’s common stockholders from continuing operations during those periods. Refer to the “7.00% Series D Cumulative Convertible Preferred Stock Repurchases” section within Note 13 – “Stockholders’ Equity” to these unaudited consolidated financial statements for further discussion of the partial repurchases of our Series D Convertible Preferred Stock.

We account for unvested restricted stock awards that contain nonforfeitable rights to dividends as participating securities and include these securities in the computation of EPS using the two-class method. Our Series D Convertible Preferred Stock and forward equity sales agreements are not participating securities and, therefore, are not included in the computation of EPS using the two-class method. Under the two-class method, we allocate net income (after dividends on preferred stock, preferred stock redemption charge, and amounts attributable to noncontrolling interests) to common stockholders and unvested restricted stock awards based on their respective participation rights to dividends declared (or accumulated) and undistributed earnings.

The table below is a reconciliation of the numerators and denominators of the basic and diluted EPS computations for the three months ended March 31, 2018 and 2017 (in thousands, except per share amounts):

Common stock, preferred stock, and excess stock authorizations

Our charter authorizes the issuance of 200.0 million shares of common stock, of which 100.7 million shares were issued and outstanding as of March 31, 2018 . Our charter also authorizes the issuance of up to 100.0 million shares of preferred stock, of which 3.0 million shares were issued and outstanding as of March 31, 2018 . In addition, 200.0 million shares of “excess stock” (as defined in our charter) are authorized, none of which were issued and outstanding as of March 31, 2018 .


14.	Noncontrolling interests

Noncontrolling interests represent the third-party interests in certain entities in which we have a controlling interest. These entities owned eight properties as of March 31, 2018 , and are included in our unaudited consolidated financial statements. Noncontrolling interests are adjusted for additional contributions and distributions, the proportionate share of the net earnings or losses, and other comprehensive income or loss. Distributions, profits, and losses related to these entities are allocated in accordance with the respective operating agreements. During the three months ended March 31, 2018 and 2017 , our consolidated joint ventures distributed $7.2 million and $5.3 million , respectively, to our joint venture partners.

We sold partial interests in 10290 Campus Point Drive and 10300 Campus Point Drive in 2016, and 9625 Towne Centre Drive in 2017. We retained controlling interests in both joint ventures following the sales and continued to consolidate these entities, therefore we accounted for the proceeds received as equity financing transactions. These transactions did not qualify as sales of real estate and did not result in purchase accounting adjustments to the carrying value. Accordingly, the carrying amounts of our partner’s share of assets and liabilities are reported at historical cost basis.

Certain of our noncontrolling interests have the right to require us to redeem their ownership interests in the respective entities. We classify these ownership interests in the entities as redeemable noncontrolling interests outside of total equity in the accompanying unaudited consolidated balance sheets. Redeemable noncontrolling interests are adjusted for additional contributions and distributions, the proportionate share of the net earnings or losses, and other comprehensive income or loss. If the amount of a redeemable noncontrolling interest is less than the maximum redemption value at the balance sheet date, such amount is adjusted to the maximum redemption value. Subsequent declines in the redemption value are recognized only to the extent that previous increases have been recognized.


15.	Assets classified as held for sale

In 2016, we decided to monetize our real estate investments located in Asia in order to invest capital into our highly leased value-creation pipeline. During 2016 and 2017, we completed the sale of all real estate investments in India and China, except for one operating property discussed below. As a result of the completion of sales in our India submarket, we also liquidated legal entities through which we owned our real estate investments in our India submarket and reclassified the remaining cumulative foreign currency translation loss of $2.4 million related to the real estate investments in India into earnings during the three months ended March 31, 2017, upon completion of the liquidations.

As of March 31, 2018 , we have one remaining real estate investment in Asia consisting of one operating property in China aggregating 334,144 RSF currently classified as held for sale. As of March 31, 2018 , cumulative unrealized foreign currency translation gains related to this property aggregated $2.1 million , which will be reclassified from accumulated other comprehensive income to net income upon completion of the sale of this remaining investment.

The following is a summary of net assets as of March 31, 2018 , and December 31, 2017 , for our remaining real estate investment in Asia that was classified as held for sale (in thousands):



	March 31, 2018			December 31, 2017
Total assets	$	32,642		$	31,578
Total liabilities	(1,946		)	(1,809		)

The loan matures on May 1, 2035 , and bears interest at a fixed rate of 4.53% .


17.	Condensed consolidating financial information

Alexandria Real Estate Equities, Inc. (the “Issuer”) has sold certain debt securities registered under the Securities Act of 1933, as amended, that are fully and unconditionally guaranteed by Alexandria Real Estate Equities, L.P. (the “LP” or the “Guarantor Subsidiary”), an indirectly 100% owned subsidiary of the Issuer. The Issuer’s other subsidiaries, including, but not limited to, the subsidiaries that own substantially all of its real estate (collectively, the “Combined Non-Guarantor Subsidiaries”), will not provide a guarantee of such securities, including the subsidiaries that are partially or 100% owned by the LP. The following condensed consolidating financial information presents the condensed consolidating balance sheets as of March 31, 2018 , and December 31, 2017 , the condensed consolidating statements of income and comprehensive income for the three months ended March 31, 2018 and 2017 , and the condensed consolidating statements of cash flows for the three months ended March 31, 2018 and 2017 , for the Issuer, the Guarantor Subsidiary, and the Combined Non-Guarantor Subsidiaries, as well as the eliminations necessary to arrive at the information on a consolidated basis. In presenting the condensed consolidating financial statements, the equity method of accounting has been applied to (i) the Issuer’s interests in the Guarantor Subsidiary and the Combined Non-Guarantor Subsidiaries, (ii) the Guarantor Subsidiary’s interests in the Combined Non-Guarantor Subsidiaries, and (iii) the Combined Non-Guarantor Subsidiaries’ interests in the Guarantor Subsidiary, where applicable, even though all such subsidiaries meet the requirements to be consolidated under GAAP. All intercompany balances and transactions between the Issuer, the Guarantor Subsidiary, and the Combined Non-Guarantor Subsidiaries have been eliminated, as shown in the column “Eliminations.” All assets and liabilities have been allocated to the Issuer, the Guarantor Subsidiary, and the Combined Non-Guarantor Subsidiaries generally based on legal entity ownership.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Certain information and statements included in this quarterly report on Form 10‑Q, including, without limitation, statements containing the words “forecast,” “guidance,” “projects,” “estimates,” “anticipates,” “believes,” “expects,” “intends,” “may,” “plans,” “seeks,” “should,” or “will,” or the negative of these words or similar words, constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements involve inherent risks and uncertainties regarding events, conditions, and financial trends that may affect our future plans of operations, business strategy, results of operations, and financial position. A number of important factors could cause actual results to differ materially from those included within or contemplated by the forward-looking statements, including, but not limited to, the following:


•	Operating factors such as a failure to operate our business successfully in comparison to market expectations or in comparison to our competitors, our inability to obtain capital when desired or refinance debt maturities when desired, and/or a failure to maintain our status as a REIT for federal tax purposes.


•	Market and industry factors such as adverse developments concerning the life science and technology industries and/or our tenants.


•	Government factors such as any unfavorable effects resulting from federal, state, local, and/or foreign government policies, laws, and/or funding levels.


•	Global factors such as negative economic, political, financial, credit market, and/or banking conditions.


•	Other factors such as climate change, cyber intrusions, and/or changes in laws, regulations, and financial accounting standards.

This list of risks and uncertainties is not exhaustive. Additional information regarding risk factors that may affect us is included under “Item 1A. Risk Factors” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our annual report on Form 10‑K for the fiscal year ended December 31, 2017 . Readers of this quarterly report on Form 10‑Q should also read our other documents filed publicly with the SEC for further discussion regarding such factors.

In addition, on December 22, 2017, the President signed a tax reform bill commonly referred to as the Tax Cuts and Jobs Act into law. The tax reform legislation is a far-reaching and complex revision to the U.S. federal income tax laws with disparate and, in some cases, countervailing effect on different categories of taxpayers and industries. The legislation is unclear in many respects and will require clarification and interpretation by the U.S. Treasury Department and the IRS in the form of amendments, technical corrections, regulations, or other forms of guidance, any of which could lessen or increase the effect of the legislation on us or our stockholders. The outcome of this legislation on state and local tax authorities, and the response by such authorities, is also unclear. We will continue to monitor changes made to, or as a result of, the federal tax law and its potential effect on us.

Overview

We are a Maryland corporation formed in October 1994 that has elected to be taxed as a REIT for federal income tax purposes. W e are an S&P 500 ^® urban office REIT uniquely focused on collaborative life science and technology campuses in AAA innovation cluster locations with a total market capitalization of $17.9 billion and an asset base in North America of 30.2 million SF as of March 31, 2018 . The asset base in North America includes 20.8 million RSF of operating properties and 3.5 million RSF of development and redevelopment of new Class A properties currently undergoing construction and pre-construction activities with target delivery dates ranging from 2018 through 2020. Additionally, the asset base in North America includes 5.9 million SF of intermediate-term and future development projects, including 3.6 million SF of intermediate-term development projects. Founded in 1994, we pioneered this niche and have since established a significant market presence in key locations, including Greater Boston, San Francisco, New York City, San Diego, Seattle, Maryland, and Research Triangle Park. We have a longstanding and proven track record of developing Class A properties clustered in urban life science and technology 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 its venture capital arm. We believe these advantages result in higher occupancy levels, longer lease terms, higher rental income, higher returns, and greater long-term asset value.

As of March 31, 2018 :


•	Investment-grade or large cap tenants represented 57% of our total annual rental revenue;


•	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, common area expenses, and other operating expenses (including increases thereto) in addition to base rent;


•	Approximately 95% of our leases (on an RSF basis) contained effective annual rent escalations that were either fixed (generally ranging from 3% to 3.5% ) or indexed based on a consumer price index or other index; and


•	Approximately 94% of our leases (on an RSF basis) provided for the recapture of capital expenditures (such as HVAC systems maintenance and/or replacement, roof replacement, and parking lot resurfacing) that we believe would typically be borne by the landlord in traditional office leases.

Our primary business objective is to maximize stockholder value by providing our stockholders with the greatest possible total return and long-term asset value based on a multifaceted platform of internal and external growth. A key element of our strategy is our unique focus on Class A properties clustered in urban campuses. These key urban campus locations are characterized by high barriers to entry for new landlords, high barriers to exit for tenants, and a limited supply of available space. They represent highly desirable locations for tenancy by life science and technology entities because of their close proximity to concentrations of specialized skills, knowledge, institutions, and related businesses. Our strategy also includes drawing upon our deep and broad real estate, life science, and technology relationships in order to identify and attract new and leading tenants and to source additional value-creation real estate.

Executive summary

Increased common stock dividend

Common stock dividend for the three months ended March 31, 2018 , of $0.90 per common share, up 7 cents , or 8% , over the three months ended March 31, 2017 ; continuation of our strategy to share growth in cash flows from operating activities with our stockholders while also retaining a significant portion for reinvestment.

Improvement in credit rating outlook

In February 2018, S&P Global Ratings raised its credit outlook for our corporate credit rating to BBB/Positive from BBB/Stable. The positive outlook reflects S&P’s belief that “there is further ratings upside over the next couple of years stemming from the company’s high quality operating portfolio and projects under development, combined with a prudent financial policy.”

Investments in real estate

A key component of our business model is our disciplined allocation of capital to the development and redevelopment of new Class A properties located in collaborative life science and technology campuses in AAA urban innovation clusters. These projects are 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 values. Our pre-construction activities are undertaken in order to get the property ready for its intended use and include entitlements, permitting, design, site work, and other activities preceding commencement of construction of aboveground building improvements. Our investments in real estate consisted of the following as of March 31, 2018 (dollars in thousands):

Results of operations

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 our most recent annual report on Form 10-K, and our subsequent quarterly reports on Form 10-Q. We believe this tabular presentation promotes a better understanding of corporate-level decisions and activities that significantly affect comparison of our operating results from period to period. We also believe this tabular presentation will supplement an understanding of our disclosures and real estate operating results. 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 from 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. Significant items, whether a gain or loss, included in the tabular disclosure for current periods are described in further detail within this Item 2 . Items included in net income attributable to Alexandria’s common stockholders are as follows:

Rental revenues

Total rental revenues for the three months ended March 31, 2018 , increased by $37.3 million , or 18.0% , to $244.5 million , compared to $207.2 million for the three months ended March 31, 2017 . The increase was primarily due to an increase in rental revenues from our Non-Same Properties totaling $30.1 million primarily related to 1,502,982 RSF of development and redevelopment projects placed into service subsequent to January 1, 2017 , and 15 operating properties totaling 1,333,498 RSF acquired subsequent to January 1, 2017 .

Rental revenues from our Same Properties for the three months ended March 31, 2018 , increased by $7.2 million , or 3.6% , to $204.4 million , compared to $197.2 million for the three months ended March 31, 2017 . The increase was primarily due to significant rental rate increases on lease renewals and re-leasing of space since January 1, 2017 . Refer to “Leasing” within the “Operating Summary” section of this Item 2 for additional information on our leasing activity.

Tenant recoveries

Tenant recoveries for the three months ended March 31, 2018 , increased by $11.8 million , or 19.3% , to $73.2 million , compared to $61.3 million for the three months ended March 31, 2017 . As of March 31, 2018 , 97% of our leases (on an RSF basis) were triple net leases, which require tenants to pay substantially all real estate taxes, insurance, utilities, common area expenses, and other operating expenses (including increases thereto) in addition to base rent. Non-Same Properties’ tenant recoveries increased by $5.6 million primarily due to the increase in recoverable operating expenses for the three months ended March 31, 2018 , as discussed under “Rental Operating Expenses” below.

Same Properties’ tenant recoveries for the three months ended March 31, 2018 , increased by $6.2 million , or 10.3% , to $66.4 million , compared to $60.2 million for the three months ended March 31, 2017 , primarily due to the increase in recoverable operating expenses for the three months ended March 31, 2018 .

Rental operating expenses

Total rental operating expenses for the three months ended March 31, 2018 , increased by $14.7 million , or 19.0% , to $91.8 million , compared to $77.1 million for the three months ended March 31, 2017 . Approximately $8.7 million of the increase was due to an increase in rental operating expenses from our Non-Same Properties primarily related to 1,502,982 RSF of development and redevelopment projects placed into service subsequent to January 1, 2017 , and 15 operating properties totaling 1,333,498 RSF acquired subsequent to January 1, 2017 .

Same Properties’ rental operating expenses increased by $6.0 million , or 8.4% , during the three months ended March 31, 2018 , compared to the three months ended March 31, 2017 , primarily due to higher property taxes and repairs and maintenance expenses during the three months ended March 31, 2018 .

General and administrative expenses

General and administrative expenses for the three months ended March 31, 2018 , increased by $3.2 million , or 16.6% , to $22.4 million , compared to $19.2 million for the three months ended March 31, 2017 . General and administrative expenses increased primarily due to the continued growth in the depth and breadth of our operations in multiple markets, including an 18.0% increase in total rental revenues to $244.5 million for the three months ended March 31, 2018 , compared to $207.2 million for the same period in 2017 , and including a 5.1 million RSF, or 20.2% , increase in our North America asset base subsequent to January 1, 2017. As a percentage of total assets, our general and administrative expenses for the three months ended March 31, 2018 and 2017 , quarter annualized, remained consistent at 0.7% .

(1)	Represents the interest rate as of the end of the applicable period, plus the effect of debt premiums/discounts, interest rate hedge agreements, and deferred financing costs.

Depreciation and amortization

Depreciation and amortization expense for the three months ended March 31, 2018 increased by $17.0 million , or 17.5% , to $114.2 million , compared to $97.2 million for the three months ended March 31, 2017 . The increase is primarily due to additional depreciation from 1,502,982 RSF of development and redevelopment projects placed into service subsequent to January 1, 2017 , and 15 operating properties totaling 1,333,498 RSF acquired subsequent to January 1, 2017 .

Investment income

Effective January 1, 2018, we adopted a new accounting standard on financial instruments. Under the new standard, changes in fair value for investments in publicly traded companies and investments in privately held entities that report NAV, and observable price changes for investments in privately held entities that do not report NAV, are recognized in investment income in our accompanying consolidated statements of income. For detailed discussion related to this new standard refer to the “Investments” section within Note 2 – “Summary of Significant Accounting Policies” and Note 6 – “Investments” to these unaudited consolidated financial statements under Item 1 of this report.

Our investment income recognized in our consolidated statement of income during the three months ended March 31, 2018 consisted of the following (in thousands):



Component	Three Months Ended March 31, 2018
Realized gains and losses	$	13,332
Unrealized gains and losses:
Investments in publicly traded companies	46,099
Investments in privately held entities without readily determinable fair values:
Investments in privately held entities that report NAV	15,087
Investments in privately held entities that do not report NAV (upward adjustments for observable price changes)	11,043
Unrealized gains and losses	72,229

Investment income	$	85,561

During the three months ended March 31, 2017 , we recognized investment income of approximately $1.5 million , which consisted of realized gains and losses on our equities securities classified as available-for-sale and equity securities accounted for under the cost method in accordance with the accounting standards in effect prior to January 1, 2018. During the three months ended March 31, 2017 , investment income was classified within other income in our consolidated statements of income. The variance between investment income recognized during the three months ended March 31, 2018 , compared to the three months ended March 31, 2017 , is primarily due to the recognition of unrealized gains and losses on our equity investments aggregating $72.2 million during the three months ended March 31, 2018 , in net income as required by the new ASU adopted on January 1, 2018. For more information, refer to the “Investments” section within Note 2 – “Summary of Significant Accounting Policies” to these unaudited consolidated financial statements under Item 1 of this report.

Sale of real estate assets

During the three months ended March 31, 2017 , we completed the sale of a vacant property at 6146 Nancy Ridge Drive located in our Sorrento Mesa submarket of San Diego for a purchase price of $3.0 million and recognized a gain of $270 thousand .

Loss on early extinguishment of debt

During the three months ended March 31, 2017 , we completed a partial principal repayment of $200 million of our 2019 Unsecured Senior Bank Term Loan, reducing the total outstanding balance from $400 million to $200 million , and recognized a loss on early extinguishment of debt of $670 thousand related to the write-off of unamortized loan fees. No such losses were recognized during the three months ended March 31, 2018 .

Preferred stock redemption charge

During the three months ended March 31, 2017 , we repurchased 501,115 outstanding shares of our Series D Convertible Preferred Stock and recognized a preferred stock redemption charge of $5.8 million .

In March 2017, we announced the redemption of our Series E Redeemable Preferred Stock and recognized a preferred stock redemption charge of $5.5 million related to the write-off of original issuance costs. On April 14, 2017 , we completed the redemption of all 5.2 million outstanding shares of our Series E Redeemable Preferred Stock.

Projected results

We present updated guidance for EPS attributable to Alexandria’s common stockholders – diluted, and funds from operations per share attributable to Alexandria’s common stockholders – diluted, based on our current view of existing market conditions and other assumptions for the year ending December 31, 2018 , as set forth, and as adjusted, in the table below. The tables below also provide a reconciliation of EPS per share attributable to Alexandria’s common stockholders – diluted, the most directly comparable GAAP measure, to funds from operations per share and funds from operations per share, as adjusted, non-GAAP measures, and other key assumptions included in our updated guidance for the year ending December 31, 2018 . Updates to guidance include: a) two cent increases to the midpoints, and reduction of the ranges from 20 cents to 10 cents for EPS - diluted, FFO per share - diluted, and FFO per share - diluted, as adjusted, and b) updating the EPS and FFO per share - diluted guidance ranges to include an investment gain of $8.3 million related to one non-real estate investment in a life science entity and unrealized gains of $72.2 million related to non-real estate investments during the three months ended March 31, 2018 . There can be no assurance that actual amounts will be materially higher or lower than these expectations. Refer to our discussion of “Forward-Looking Statements” within this Item 2.

Refer to the “Investments” section within Note 2 – “Summary of Significant Accounting Policies” to these unaudited consolidated financial statements under Item 1 for additional information.

(3)

The completion of our development and redevelopment projects will result in an increase in interest expense and other project costs because these project costs will no longer qualify for capitalization and will, therefore, be expensed as incurred. Our assumptions for occupancy, rental rate growth, Same Properties net operating income growth, straight-line rent revenue, general and administrative expenses, capitalization of interest, and interest expense are included in the tables above and are subject to a number of variables and uncertainties, including those discussed as “Forward-Looking Statements” under Part I; “Item 1A. Risk Factors”; and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our annual report on Form 10‑K for the year ended December 31, 2017 . To the extent our full-year earnings guidance is updated during the year, we will provide additional disclosure supporting reasons for any significant changes to such guidance.


(4)	Approximately 50% of straight-line rent revenue represents initial free rent on recently delivered and expected 2018 deliveries of new Class A properties from our development and redevelopment pipeline.

Consolidated and unconsolidated real estate joint ventures

We present components of balance sheet and operating results information for the noncontrolling interests’ share of our consolidated real estate joint ventures and for our share of investments in unconsolidated real estate joint ventures to help investors estimate balance sheet and operating results information related to our partially owned entities. These amounts are estimated by computing, for each joint venture that we consolidate in our financial statements, the noncontrolling interest percentage of each financial item to arrive at the cumulative noncontrolling interest share of each component presented. In addition, for our real estate joint ventures that we do not control and do not consolidate, we apply our economic ownership percentage to the unconsolidated real estate joint ventures to arrive at our proportionate share of each component presented. Refer to Note 4 – “Consolidated and Unconsolidated Real Estate Joint Ventures” to these unaudited consolidated financial statements under Item 1 of this report for further discussion.

Investments

Adoption of new accounting standard on financial instruments

On January 1, 2018, we adopted a new accounting standard which requires us, on a prospective basis, to present our equity investments at fair value whenever fair value is readily available or observable. During the three months ended March 31, 2018 , we recognized within earnings approximately $72 million of unrealized gains from changes in fair value of investments in publicly traded companies and investments in privately held entities without readily determinable fair values.

We expect to meet certain long-term liquidity requirements, such as requirements for development, redevelopment, other construction projects, capital improvements, tenant improvements, property acquisitions, leasing costs, non-revenue-enhancing capital expenditures, scheduled debt maturities, distributions to noncontrolling interests, repurchase/redemption of preferred stock, and dividends through net cash provided by operating activities, periodic asset sales, strategic real estate joint venture capital, and long-term secured and unsecured indebtedness, including borrowings under our $1.65 billion unsecured senior line of credit, unsecured senior bank term loans, and the issuance of additional debt and/or equity securities, including settlement of our forward equity sales agreements.

We expect to continue meeting our short-term liquidity and capital requirements, as further detailed in this section, generally through our working capital and net cash provided by operating activities. We believe that the net cash provided by operating activities will continue to be sufficient to enable us to make the distributions necessary to continue qualifying as a REIT.

Over the next several years, our balance sheet, capital structure, and liquidity objectives are as follows:


•	Retain positive cash flows from operating activities after payment of dividends and distributions to noncontrolling interests for investment in development and redevelopment projects and/or acquisitions;


•	Improve credit profile and long-term cost of capital;


•	Maintain diverse sources of capital, including sources from net cash provided by operating activities, unsecured debt, secured debt, selective asset sales, partial interests sales, preferred stock, and common stock;


•	Maintain commitment to long-term capital to fund growth;


•	Maintain prudent laddering of debt maturities;


•	Maintain solid credit metrics;


•	Maintain significant balance sheet liquidity;


•	Mitigate unhedged variable-rate debt exposure through the reduction of short-term and medium-term variable-rate bank debt;


•	Maintain a large unencumbered asset pool to provide financial flexibility;


•	Fund preferred stock and common stock dividends and distributions to noncontrolling interests from net cash provided by operating activities;


•	Manage a disciplined level of value-creation projects as a percentage of our gross investments in real estate; and


•	Maintain high levels of pre-leasing and percentage leased in value-creation projects.

The following table presents the availability under our $1.65 billion unsecured senior line of credit, available commitments under our secured construction loans, investments in publicly traded companies, outstanding forward equity sales agreements, cash, cash equivalents, and restricted cash as of March 31, 2018 (dollars in thousands):

Cash, cash equivalents, and restricted cash

As of March 31, 2018 , and December 31, 2017 , we had $259.0 million and $277.2 million , respectively, of cash, cash equivalents, and restricted cash. We expect existing cash, cash equivalents, and restricted cash, cash flows from operating activities, proceeds from asset sales, borrowings under our $1.65 billion unsecured senior line of credit, secured construction loan borrowings, issuances of unsecured notes payable, and issuances of common stock to continue to be sufficient to fund our operating activities and cash commitments for investing and financing activities, such as regular quarterly dividends, distribution to noncontrolling interests, scheduled debt repayments, acquisitions, and certain capital expenditures, including expenditures related to construction activities.

Cash flows

We report and analyze our cash flows based on operating activities, investing activities, and financing activities. The following table summarizes changes in our cash flows (in thousands):



	Three Months Ended March 31,
	2018			2017			Change
Net cash provided by operating activities	$	128,921		$	107,644		$	21,277
Net cash used in investing activities	$	(598,038	)	$	(468,356	)	$	(129,682	)
Net cash provided by financing activities	$	451,319		$	388,690		$	62,629

Operating activities

Cash flows provided by operating activities are primarily dependent upon the occupancy level of our asset base, the rental rates of our leases, the collectability of rent and recovery of operating expenses from our tenants, the timing of completion of development and redevelopment projects, and the timing of acquisitions and dispositions of operating properties. Net cash provided by operating activities for the three months ended March 31, 2018 , increased to $128.9 million , compared to $107.6 million for the three months ended March 31, 2017 . This increase was primarily attributable to (i) cash flows generated by our highly leased development and redevelopment projects recently placed into service, (ii) income-producing acquisitions since January 1, 2017 , and (iii) increases in rental rates on lease renewals and re-leasing of space since January 1, 2017 .

Investing activities

Cash flows used in investing activities for the three months ended March 31, 2018 and 2017 , consisted of the following (in thousands):

Net cash used in investing activities	$	(598,038	)	$	(468,356	)	$	(129,682	)

The change in net cash used in investing activities for the three months ended March 31, 2018 , is primarily due to an increased use of cash for property acquisitions and construction related to our highly leased pipeline. Refer to Note 3 – “Investments in Real Estate” and Note 6 – “Investments” to these unaudited consolidated financial statements under Item 1 of this report for further information.

Capital resources

We expect that our principal liquidity needs for the year ending December 31, 2018 , will be satisfied by the following multiple sources of capital, as shown in the table below. There can be no assurance that our sources and uses of capital will not be materially higher or lower than these expectations.

We have completed transactions aggregating $908 million through April 2018. This includes completed and projected settlement of our forward equity sales agreements and completed sales under our ATM program, including 6.9 million shares of our common stock subject to forward equity sales agreements executed in January 2018. Additionally, in March 2018, we settled 843,600 shares from the forward equity sales agreements and received proceeds of $100.2 million , net of underwriting discounts and adjustments provided in the forward equity sales agreements. We expect to receive proceeds of $713.7 million upon settlement of the remaining outstanding forward equity sales agreements, to be further adjusted as provided in the sales agreements, in 2018. Also, includes 782,967 shares of common stock sold in April 2018 under our ATM program at $122.20 per share, with net proceeds of $94.2 million .


(2)	Refer to the “Acquisitions” section within this Item 2 for additional information.

The key assumptions behind the sources and uses of capital in the table above include a favorable capital market environment, performance of our core operating properties, lease-up and delivery of current and future development and redevelopment projects, and leasing activity. Our expected sources and uses of capital are subject to a number of variables and uncertainties, including those discussed as “Forward-Looking Statements” under Part I; “Item 1A. Risk Factors”; and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our annual report on Form 10‑K for the year ended December 31, 2017 . We expect to update our forecast of sources and uses of capital on a quarterly basis.

Sources of capital

Net cash provided by operating activities after dividends

We expect to retain $140.0 million to $180.0 million of net cash flows from operating activities after payment of common stock and preferred stock dividends, and distributions to noncontrolling interests. Changes in operating assets and liabilities are excluded from this calculation as they represent timing differences. For the year ending December 31, 2018 , we expect our recently delivered projects, our highly pre-leased value-creation projects expected to be completed, along with contributions from Same Properties and recently acquired properties, to contribute significant increases in rental revenue, net operating income, and cash flows. We anticipate significant contractual near-term growth in annual cash rents of $76 million , of which $60 million will commence through the fourth quarter of 2018 ( $35 million in the second quarter of 2018, $13 million in third quarter of 2018, and $12 million in the fourth quarter of 2018). This is related to initial free rent granted on development and redevelopment projects recently placed into service (and no longer in our value-creation pipeline) that are currently generating rental revenue. Refer to the “Cash Flows” section within this Item 2 of this report for a discussion of net cash provided by operating activities for the year ended March 31, 2018 .

Debt

The table below reflects the outstanding balances, maturity dates, applicable margins, and facility fees for each of the following facilities (dollars in thousands):



	As of March 31, 2018
Facility	Balance		Maturity Date ⁽¹⁾	Applicable Margin	Facility Fee
$1.65 billion unsecured senior line of credit	$	490,000	October 2021	L+1.00%	0.20%
2019 Unsecured Senior Bank Term Loan	$	199,622	January 2019	L+1.20%	N/A
2021 Unsecured Senior Bank Term Loan	$	348,575	January 2021	L+1.10%	N/A


(1)	Includes any extension options that we control.

Borrowings under the $1.65 billion unsecured senior line of credit bear interest at LIBOR or the base rate specified in the amended $1.65 billion unsecured senior line of credit agreement plus, in either case, a specified margin (the “Applicable Margin”). The Applicable Margin for LIBOR borrowings under the $1.65 billion unsecured senior line of credit is based on our existing credit ratings as set by certain rating agencies.

We use our $1.65 billion unsecured senior line of credit to fund working capital, construction activities, and, from time to time, acquisition of properties. Borrowings under the $1.65 billion unsecured senior line of credit will bear interest at a “Eurocurrency Rate” or a “Base Rate” specified in the amended $1.65 billion unsecured line of credit agreement plus, in either case, the Applicable Margin. The Eurocurrency Rate specified in the amended $1.65 billion unsecured line of credit agreement is, as applicable, the rate per annum equal to either (i) the LIBOR or a successor rate thereto as approved by the administrative agent for loans denominated in a LIBOR quoted currency (i.e., U.S. dollars, euro, sterling, or yen), (ii) the average annual yield rates applicable to Canadian dollar bankers’ acceptances for loans denominated in Canadian dollars, (iii) the Bank Bill Swap Reference Bid rate for loans denominated in Australian dollars, or (iv) the rate designated with respect to the applicable alternative currency for loans denominated in a non-LIBOR quoted currency (other than Canadian or Australian dollars). The Base Rate means, for any day, a fluctuating rate per annum, equal to the highest of (i) the federal funds rate plus 1/2 of 1.00%, (ii) the rate of interest in effect for such day as publicly announced from time to time, by Bank of America as its “prime rate,” and (iii) the Eurocurrency Rate plus 1.00%. Our $1.65 billion unsecured senior line of credit contains a feature that allows lenders to competitively bid on the interest rate for borrowings under the facility. This may result in an interest rate that is below the stated rate. In addition to the cost of borrowing, the facility is subject to an annual facility fee of 0.20% based on the aggregate commitments outstanding.

We expect to fund a significant portion of our capital needs in 2018 from the issuance of unsecured senior notes payable, and from borrowings under our $1.65 billion unsecured senior line of credit.

In March 2017, we completed an offering of $425.0 million of unsecured senior notes, due in 2028 , at an interest rate of 3.95% . Net proceeds of $420.5 million were used initially to reduce outstanding borrowings on our $1.65 billion unsecured senior line of credit.

Refer to the “3.95% Unsecured Senior Notes Payable Due in 2028” section within Note 9 – “Secured and Unsecured Senior Debt” to our unaudited consolidated financial statements under Item 1 of this report for additional information regarding our unsecured senior notes payable.

During the three months ended March 31, 2017 , we completed a partial repayment of $200 million of our 2019 Unsecured Senior Bank Term Loan, reducing the total outstanding balance from $400 million to $200 million , and recognized a loss on early extinguishment of debt of $670 thousand related to the write-off of unamortized loan fees.

Real estate dispositions and common equity

We expect to continue the disciplined execution of select sales of non-strategic land and non-core operating assets. The sale of non-strategic land and non-core operating assets provides an important source of capital to fund a portion of our highly leased value-creation development and redevelopment projects. We may also consider additional sales of partial interests in core Class A properties and/or development projects. For 2018 , we expect real estate dispositions, partial interest sales, and issuances of common equity ranging from $1.1 billion to $1.3 billion . The amount of asset sales necessary to meet our forecasted sources of capital will vary depending upon the amount of EBITDA associated with the assets sold. In addition, the amount of common equity issued will be subject to market conditions.

For additional information, refer to the “Real Estate Asset Sales” under the “Investments in Real Estate” section within this Item 2.

ATM common stock offering program

In October 2016, we established an ATM common stock offering program that allowed us to sell up to an aggregate of $600.0 million of our common stock. During the six months ended June 30, 2017, we completed our ATM program with the sale of 2.1 million shares of common stock for gross proceeds of $245.8 million , or $118.97 per share, and net proceeds of approximately $241.8 million .

In August 2017, we established a new ATM common stock offering program that allows us to sell up to an aggregate of $750.0 million of our common stock. As of December 31, 2017 , we sold an aggregate of 2.8 million shares of common stock under this program for gross proceeds of $336.6 million , or $121.37 per share, and received net proceeds of $331.2 million . As of March 31, 2018 , the remaining aggregate amount available under our current program for future sales of common stock was $413.4 million . During the three months ended March 31, 2018 , we did not sell any shares under this program. During April 2018, we sold 782,967 shares of common stock under our ATM program for $122.20 per share and received net proceeds of $94.2 million .

Forward equity sales agreements

In March 2017, we executed an offering to sell an aggregate 6.9 million shares of our common stock, consisting of an initial issuance of 2.1 million shares and the remaining 4.8 million shares subject to forward equity sales agreements, at a public offering price of $108.55 per share, less underwriters’ discount. Approximately 60% of the proceeds was initially targeted to fund value-creation acquisitions and construction, with approximately 40% targeted to fund balance sheet improvements, including reduction in our projected net debt to Adjusted EBITDA – fourth quarter of 2017, annualized by 0.2x, and redemption of our Series E Redeemable Preferred Stock. Aggregate net proceeds from the sale, after underwriters’ discount and issuance costs, of $702.4 million consisted of the following:


•	2.1 million shares issued at closing in March 2017 with net proceeds of $217.8 million ; and


•	4.8 million shares issued in December 2017 with net proceeds of $484.6 million .

In January 2018, we entered into forward equity sales agreements to sell an aggregate 6.9 million shares of our common stock (including the exercise of underwriters’ option to purchase an additional 900,000 shares), at a public offering price of $123.50 per share, before underwriting discounts. The agreements must be settled no later than April 8, 2019. In March 2018, we settled 843,600 shares from our forward equity sales agreements and received proceeds of $100.2 million , net of underwriting discounts and adjustments provided in the forward equity sales agreements. We expect to settle the remaining shares under our forward sales agreements in 2018 and expect to receive proceeds of $713.7 million upon settlement of the remaining outstanding forward equity sales agreements, which will be further adjusted as provided in the forward equity sales agreements. We intend to use the net proceeds received upon the settlement of the forward equity sales agreements to fund acquisitions and the construction of on-going highly leased development projects, with any remaining proceeds to be held for general working capital and other corporate purposes, including the reduction of the outstanding balance on our unsecured senior line of credit, if any.

Other sources

Under our current shelf registration statement filed with the SEC, we may offer common stock, preferred stock, debt, and other securities. These securities may be issued, from time to time, at our discretion based on our needs and market conditions, including, as necessary to balance our use of incremental debt capital.

Additionally, we hold interests, together with joint venture partners, in joint ventures that we consolidate in our financial statements. These joint venture partners may contribute equity into these entities primarily related to their share of funds for construction and financing-related activities. During the three months ended March 31, 2018 , we received $6.6 million in contributions from and sales of noncontrolling interests.

Uses of capital

Summary of capital expenditures

Our primary use of capital relates to the development, redevelopment, pre-construction, and construction of properties. We currently have projects in our visible growth pipeline aggregating 3.5 million RSF of new Class A office/laboratory and tech office space, and intermediate-term and future value-creation projects supporting an aggregate of 5.9 million SF of ground-up development in North America. We incur capitalized construction costs related to development, redevelopment, pre-construction, and other construction activities. We also incur additional capitalized project costs, including interest, property taxes, insurance, and other costs directly related and essential to the development, redevelopment, pre-construction, or construction of a project, during periods when activities necessary to prepare an asset for its intended use are in progress. Refer to the “Development and Redevelopment of New Class A Properties: 2018 – 2020 Deliveries”, and “Summary of Capital Expenditures” sections under “Investments in Real Estate” within this Item 2 for more information on our capital expenditures.

We capitalize interest cost as a cost of the project only during the period for which activities necessary to prepare an asset for its intended use are ongoing, provided that expenditures for the asset have been made and interest cost has been incurred. Capitalized interest for the three months ended March 31, 2018 and 2017 , of $13.4 million and $13.2 million , respectively, is classified in investments in real estate. Indirect project costs, including construction administration, legal fees, and office costs that clearly relate to projects under development or construction, are capitalized as incurred during the period an asset is undergoing activities to prepare it for its intended use. We capitalized payroll and other indirect project costs related to development, redevelopment, pre-construction, and construction projects, which aggregated $5.6 million for the three months ended March 31, 2018 and 2017 , respectively. Capitalized payroll and other indirect project costs for the three months ended March 31, 2018 , compared to the same period in 2017 , remained consistent. 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. Should we cease activities necessary to prepare an asset for its intended use, the interest, taxes, insurance, and certain other direct project costs related to this asset would be expensed as incurred. Expenditures for repairs and maintenance are expensed as incurred.

Fluctuations in our development, redevelopment, and construction activities could result in significant changes to total expenses and net income. For example, had we experienced a 10% reduction in development, redevelopment, and construction activities without a corresponding decrease in indirect project costs, including interest and payroll, total expenses would have increased by approximately $1.9 million for the three months ended March 31, 2018 .

We also capitalize and defer initial direct costs to originate leases with independent third parties related to evaluating a prospective lessee’s financial condition, negotiating lease terms, preparing the lease agreement, and closing the lease transaction. Costs that we capitalized and deferred relate to successful leasing transactions, result directly from and are essential to the lease transaction, and would not have been incurred had that lease transaction not occurred. The initial direct costs capitalized and deferred also include the portion of our employees’ total compensation and payroll-related benefits directly related to time spent performing the activities described above and related to the respective lease that would not have been performed but for that lease. Total initial direct leasing costs capitalized during the three months ended March 31, 2018 and 2017 , were $15.5 million and $17.0 million , respectively, of which $4.2 million and $4.0 million , respectively, represented capitalized and deferred payroll costs and legal costs directly related and essential to our leasing activities during each respective period. The decrease in direct leasing costs capitalized during the three months ended March 31, 2018 , compared to three months ended March 31, 2017 , was due to a decrease in leasing activity related to our consolidated properties. Our overall leasing activity increased to approximately 1.5 million RSF for the three months ended March 31, 2018 compared to 1.3 million RSF for the three months ended March 31, 2017 . However, a greater portion of the RSF leased during the three months ended March 31, 2018 , related to leases at properties owned by our unconsolidated joint ventures. Leasing costs incurred by our unconsolidated joint ventures are accounted for under the equity method of accounting, and are not reflected in the total initial direct leasing costs reported above.

Acquisitions

Refer to the “Acquisitions” section within Note 3 – “Investments in Real Estate” to our unaudited consolidated financial statements under Item 1 and “Acquisitions” under the “Investments in Real Estate” section within this Item 2 of this report for more information on our acquisitions.

7.00% Series D cumulative convertible preferred stock repurchases

As of March 31, 2018 , we had 3.0 million shares of our Series D Convertible Preferred Stock outstanding. During the three months ended March 31, 2018 , we did not repurchase any additional outstanding shares of our Series D Convertible Preferred Stock.

However, during 2018, we may seek to repurchase additional shares of our Series D Convertible Preferred Stock, subject to market conditions. To the extent that we repurchase additional shares of our Series D Convertible Preferred Stock, we expect to fund such amounts with the proceeds from issuances of our common stock, subject to market conditions.

6.45% Series E cumulative redeemable preferred stock redemption

In March 2017, we announced the redemption of our Series E Redeemable Preferred Stock. On April 14, 2017 , we completed the redemption of all 5.2 million outstanding shares of our Series E Redeemable Preferred Stock at a redemption price of $25.00 per share, or an aggregate $130.0 million , plus accrued dividends.

Dividends

During the three months ended March 31, 2018 and 2017 , we paid the following dividends (in thousands):



	Three Months Ended March 31,
	2018		2017		Change
Common stock dividends	$	91,060	$	73,705	$	17,355
7.00% Series D cumulative convertible preferred stock dividends	1,302		1,520		(218		)
6.45% Series E cumulative redeemable preferred stock dividends	—		2,097		(2,097		)
	$	92,362	$	77,322	$	15,040

The increase in dividends paid on our common stock for the three months ended March 31, 2018 , compared to the three months ended March 31, 2017 , was primarily due to an increase in number of common shares outstanding at each record date of December 31, 2017 , and December 31, 2016 , as a result of common stock issuances under our ATM program, settlement of forward equity sales agreements, and partially due to the increase in the related dividends to $0.90 per common share paid during the three months ended March 31, 2018 , from $0.83 per common share paid during the three months ended March 31, 2017 . Dividends paid on our Series D Convertible Preferred Stock remained consistent for the three months ended March 31, 2018 and 2017 , respectively. The decrease in dividends paid on our Series E Redeemable Preferred Stock was due to the redemption of all 5.2 million outstanding shares of our Series E Redeemable Preferred Stock on April 14, 2017 .

Estimated interest payments

Estimated interest payments on our fixed-rate and hedged variable-rate debt were calculated based upon contractual interest rates, including estimated interest expense related to interest rate hedge agreements, interest payment dates, and scheduled maturity dates. As of March 31, 2018 , approximately 85% of our debt was fixed-rate debt or variable-rate debt subject to interest rate hedge agreements. Refer to Note 10 – “Interest Rate Hedge Agreements” to our unaudited consolidated financial statements under Item 1 of this report for further information. The remaining 15% of our debt as of March 31, 2018 , was unhedged variable-rate debt based primarily on LIBOR. Interest payments on our unhedged variable-rate debt have been calculated based on interest rates in effect as of March 31, 2018 . Refer to Note 9 – “Secured and Unsecured Senior Debt” to our unaudited consolidated financial statements under Item 1 of this report for additional information regarding our debt.

Interest rate hedge agreements

We utilize interest rate derivatives to hedge a portion of our exposure to volatility in variable interest rates primarily associated with our $1.65 billion unsecured senior line of credit, unsecured senior bank term loans, and variable-rate secured construction loans. Our derivative instruments consisted of interest rate swaps.

Our interest rate swap agreements involve the receipt of variable-rate amounts from a counterparty in exchange for our payment of fixed-rate amounts to the counterparty over the life of the agreement without the exchange of the underlying notional amount. Interest received under all of our interest rate swap agreements is based on one-month LIBOR. The net difference between the interest paid and the interest received is reflected as an adjustment to interest expense in our consolidated statements of income.

We have entered into master derivative agreements with our counterparties. These master derivative agreements (all of which are adapted from the standard International Swaps and Derivatives Association, Inc. form) define certain terms between us and each of our respective counterparties to address and minimize certain risks associated with our interest rate hedge agreements. In order to limit our risk of non-performance by an individual counterparty under our interest rate hedge agreements, these agreements are spread among various counterparties. The largest aggregate notional amount in effect at any single point in time with an individual counterparty in our interest rate hedge agreements existing as of March 31, 2018 , was $100.0 million . If one or more of our counterparties fail to perform under our interest rate hedge agreements, we may incur higher costs associated with our variable-rate LIBOR-based debt than the interest costs we originally anticipated. We have not posted any collateral related to our interest rate hedge agreements.

Ground lease obligations

Ground lease obligations as of March 31, 2018 , included leases for 27 of our properties, which accounted for approximately 12% of our total number of properties, and one land development parcel. Excluding one ground lease related to one operating property that expires in 2036 with a net book value of $9.1 million as of March 31, 2018 , our ground lease obligations have remaining lease terms ranging from approximately 36 to 97 years, including extension options.

As of March 31, 2018 , the remaining contractual payments under our ground and office lease agreements for which we are the lessee aggregated $586.9 million and $3.8 million , respectively. Under the new lease ASU effective on January 1, 2019, described in detail under the “Lease accounting” subsection of “Recent accounting pronouncements” section within Note 2 – “Summary of Significant Accounting Policies” to our unaudited consolidated financial statements under Item 1 of this report, we will be required to recognize a right-of-use asset and a related liability to account for our future obligations under our ground and office lease arrangements for which we are the lessee. The lease liability will be measured based on the present value of the remaining lease payments. The right-of-use asset will be equal to the corresponding lease liability, adjusted for initial direct leasing cost and any other consideration exchanged with the landlord prior to the commencement of the lease. As of March 31, 2018 , the estimated present value of the remaining contractual payments under our ground and office lease agreements for which we are the lessee is in the range from $170.0 million to $230.0 million .

Commitments

As of March 31, 2018 , remaining aggregate costs under contract for the construction of properties undergoing development, redevelopment, and improvements under the terms of leases approximated $630.2 million . We expect payments for these obligations to occur over one to three years, subject to capital planning adjustments from time to time. We may have the ability to cease the construction of certain properties, which would result in the reduction of our commitments. We have existing office space at 161 First Street/50 Rogers Street in our Alexandria Center ^® at Kendall Square (“ACKS”) campus that we are required to partially convert to multifamily residential space, pursuant to our entitlements for our ACKS campus. Pursuant to these requirements, we expect to begin construction of the conversion to multifamily residential in 2018. In addition, we have letters of credit and performance obligations aggregating $840 thousand primarily related to construction projects.

In March 2018, we acquired a 10% interest in a real estate joint venture with Uber and the Golden State Warriors at 1655 and 1725 Third Street, located in our Mission Bay/SoMa submarket. Our total equity contribution commitment is $78.0 million , of which we have contributed $32.0 million through March 31, 2018 . In November 2017, we entered into an agreement with a real estate developer in the San Francisco Bay Area to own a 49% interest in a real estate joint venture at Menlo Gateway in our Greater Stanford submarket of San Francisco. Our total equity contribution commitment is $269.0 million , of which we have contributed $94.0 million through March 31, 2018 .

We are also committed to funding approximately $175.7 million for non-real estate investments over the next several years.

Exposure to environmental liabilities

In connection with the acquisition of all of our properties, we have obtained Phase I environmental assessments to ascertain the existence of any environmental liabilities or other issues. The Phase I environmental assessments of our properties have not revealed any environmental liabilities that we believe would have a material adverse effect on our financial condition or results of operations taken as a whole, nor are we aware of any material environmental liabilities that have occurred since the Phase I environmental assessments were completed. In addition, we carry a policy of pollution legal liability insurance covering exposure to certain environmental losses at substantially all of our properties.

(1)

On January 1, 2018, we adopted an ASU that amended the accounting for investments. Upon adoption, we reclassified cumulative net unrealized gains related to public investments aggregating $49.8 million related to investments with fair values from accumulated other comprehensive income to retained earnings. Additionally, we recognized a cumulative adjustment aggregating $90.8 million to retained earnings related to private investments in limited partnerships that report NAV per share.

Interest rate hedge agreements

Changes in our accumulated other comprehensive income balance relate to the change in fair value of our interest rate hedge agreements. We reclassify amounts from accumulated other comprehensive income as we recognize interest expense related to the hedged variable-rate debt instrument.

Foreign currency translation

Changes in our accumulated other comprehensive income balance relate to changes in the foreign exchange rates for our real estate investments in Canada and Asia. Additionally, we reclassify unrealized foreign currency translation gains and losses into net income as we dispose of these holdings.

Critical accounting policies

Refer to our annual report on Form 10‑K for the year ended December 31, 2017 , for a discussion of our critical accounting policies related to investments in real estate and properties classified as held for sale, impairment of long-lived assets, capitalization of costs, recognition of rental revenue and tenant recoveries, and monitoring of tenant credit quality. There were no significant changes to these policies during the three months ended March 31, 2018 . The changes to our critical accounting policies related to accounting for our equity investments in publicly traded companies and privately held entities primarily involved in the life science and technology industries are discussed below.

Prior to January 1, 2018

Effective January 1, 2018

•


•	Investments in privately held entities without readily determinable fair values fall into two categories:


•	Investments in privately held entities that report net asset value per share (“NAV”), such as our privately held investments in limited partnerships, are carried at fair value using NAV as a practical expedient with changes in fair value recognized in net income.


•	Investments in privately held entities that do not report NAV are accounted for using a measurement alternative which allows these investments to be measured at cost, adjusted for observable price changes and impairments, with changes recognized in net income.

100

For investments in privately held entities that do not report NAV, 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, 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.

Investments in privately held entities will continue to be accounted for under the equity method unless our interest in the entity was deemed to be so minor that we have virtually no influence over the entity’s operating and financial policies. Under the equity method of accounting, we recognized our investment initially at cost and adjust the carrying amount of the investment to recognize our share of the earnings or losses of the investee subsequent to the date of our investment.

Initial adoption of new ASU

On January 1, 2018, we recognized the following adjustments upon adoption of the new ASU:


•	For investments in publicly traded companies, reclassification of cumulative unrealized gains and losses as of December 31, 2017, aggregating $49.8 million , from accumulated other comprehensive income to retained earnings.


•	For investments in privately held entities without readily determinable fair values that were previously accounted for under the cost method:


•	Adjustment to investments for cumulative unrealized gains related to investments in privately held entities that report NAV, representing the difference between fair values as of December 31, 2017, using NAV as a practical expedient, and the carrying value of the investments as of December 31, 2017, aggregating $90.8 million , with a corresponding adjustment to retained earnings.

•

Non-GAAP measures

This section contains additional information of certain non-GAAP financial measures and the reasons why we use these supplemental measures of performance and believe they provide useful information to investors, as well as the definitions of other terms used in this report.

Funds from operations and funds from operations, as adjusted, attributable to Alexandria Real Estate Equities, Inc.’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. We compute funds from operations in accordance with standards established by the Nareit Board of Governors in its April 2002 White Paper and related implementation guidance (the “Nareit White Paper”). The Nareit White Paper defines funds from operations as net income (computed in accordance with GAAP), excluding gains (losses) from sales of depreciable real estate and land parcels, and impairments of depreciable real estate (excluding land parcels), 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. The definition of funds from operations in the Nareit White Paper does not include adjustments related to unrealized gains and losses on non-real estate investments, which are affected by market conditions outside of our control. Consequently, unrealized gains and losses on non-real estate investments recognized in earnings, affects our reported funds from operations as computed in accordance with the Nareit White Paper.

We compute funds from operations, as adjusted, as funds from operations calculated in accordance with the Nareit White Paper excluding significant realized gains or losses on the sale of non-real estate investments, unrealized gains or losses on non-real estate investments, losses on early extinguishment of debt, preferred stock redemption charges, impairments of non-depreciable real estate, impairments of non-real estate investments, and 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 tables present a reconciliation of net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders, the most directly comparable financial measure calculated and presented in accordance with GAAP, including our share of amounts from consolidated and unconsolidated real estate joint ventures, to funds from operations attributable to Alexandria Real Estate Equities, Inc.’s common stockholders – diluted, and funds from operations attributable to Alexandria Real Estate Equities, Inc.’s common stockholders – diluted, as adjusted, and the related per share amounts.

Adjusted EBITDA and Adjusted EBITDA margins

We use Adjusted EBITDA as a supplemental performance measure of our operations, for financial and operational decision making, and as a supplemental or additional 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 land parcels, unrealized gains or losses on non-real estate investments, and impairments.

We believe Adjusted EBITDA provides investors with relevant and useful information, as it allows investors to evaluate our operating performance 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. For example, we exclude gains or losses on the early extinguishment of debt to allow investors to measure our performance independent of our capital structure and indebtedness. We believe that adjusting for the effects of impairments and gains or losses on sales of real estate allows investors to evaluate performance from period to period on a consistent basis without having to account for differences recognized because of real estate investment and disposition decisions. We believe that excluding charges related to share-based compensation and unrealized gains or losses on non-real estate investments facilitates a comparison of our operations across periods without the variances caused by the volatility of the amounts (which depends on market forces outside our control). Adjusted EBITDA has limitations as a measure of our performance. Adjusted EBITDA does not reflect our historical cash expenditures or future cash requirements for capital expenditures or contractual commitments. While Adjusted EBITDA is a relevant measure of performance, it does not represent net income 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.

The following table reconciles net income, the most directly comparable financial measure calculated and presented in accordance with GAAP, to Adjusted EBITDA (dollars in thousands):



	Three Months Ended March 31,
	2018			2017
Net income	$	141,518		$	47,555
Interest expense	36,915			29,784

Loss on early extinguishment of debt	—			670
Gain on sales of real estate – rental properties	—			(270		)
Unrealized gain on non-real estate investments	(72,229		)	—
Adjusted EBITDA	$	228,611		$	180,941

Revenues, as adjusted ⁽¹⁾	$	333,471		$	270,877

Adjusted EBITDA Margins	69		%	67		%


(1)	Revenues, as adjusted, include realized gains or losses on non-real estate investments. We use revenues, as adjusted, in our calculation of Adjusted EBITDA margin. We believe using revenues, as adjusted, provides a more accurate Adjusted EBITDA margin calculation.

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 March 31, 2018 , 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, 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 are classified in “tenant recoveries” in our consolidated statements of income.

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. See 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.

105

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 fixed-charge coverage ratio calculation below is not directly comparable to the computation of ratio of earnings to fixed charges as defined in Item 503(d) of Regulation S-K and to the “Computation of Consolidated Ratio of Earnings to Fixed Charges and Computation of Consolidated Ratio of Earnings to Combined Fixed Charges and Preferred Stock Dividends” included in Exhibit 12.1 to this quarterly report on Form 10‑Q.

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 (dollars in thousands):



	Three Months Ended March 31,
	2018			2017
Adjusted EBITDA	$	228,611		$	180,941

Interest expense	$	36,915		$	29,784

Fixed-charge coverage ratio:
– period annualized	4.6x			4.1x
– trailing 12 months	4.3x			3.8x

Development, redevelopment, and pre-construction

Development projects 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 or tech office space. We generally will not commence new development projects for aboveground construction of new Class A office/laboratory and tech office 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.

106

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 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 large cap tenants

Investment-grade or large cap tenants include tenants that are investment-grade rated or have their most recently reported market capitalization or private valuation greater than $10 billion as of March 31, 2018 .

Joint venture financial information

We present components of balance sheet and operating results information related to our joint ventures, which are not in accordance with or intended to be presentations 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. The joint venture agreement for each entity that we do not wholly own 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 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. Refer to Note 4 – “Consolidated and Unconsolidated Real Estate Joint Ventures” to our unaudited consolidated financial statements under Item 1 of this report for more information on our unconsolidated real estate joint ventures.

We believe that in order to facilitate 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 income 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.

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.

107

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 period end. Refer to “Adjusted EBITDA” within this section of this Item 2 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 as of March 31, 2018 , and December 31, 2017 (dollars in thousands):

Net operating income and operating margin

The following table reconciles net income to total net operating income (in thousands):



	Three Months Ended March 31,
	2018			2017
Net income	$	141,518		$	47,555

Equity in earnings of unconsolidated real estate joint ventures	(1,144		)	(361		)
General and administrative expenses	22,421			19,229
Interest expense	36,915			29,784

Net operating income	$	228,368		$	193,790

Revenues	$	320,139		$	270,877

Operating margin	71%			72%

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 (losses) 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. 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 evaluating the operating performance of our 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.

Further, we believe net operating income is useful to investors as a performance measure 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. 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 on a straight-line basis 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 and deterioration in market conditions. We also exclude realized and unrealized investment income 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 loss on early extinguishment of debt, as these charges often relate to corporate strategy. Property operating expenses that are 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

109

rent, and office supplies that are incurred as part of corporate office management. We believe that in order to facilitate a clear understanding of our operating results, net operating income should be examined in conjunction with net income as presented in our consolidated statements of income. Net operating income should not be considered as an alternative to net income as an indication of our performance, nor as an alternative to cash flows as a measure either of 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 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 rate revenue, see 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 rental revenues, tenant recoveries, 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 period, we analyze the operating performance for all properties that were fully operating for the entirety of the comparative periods presented, referred to as same properties. These properties are analyzed separately from properties acquired subsequent to the first day in the earliest comparable period presented, properties that underwent development or redevelopment at any time during the comparative periods, and corporate entities (legal entities performing general and administrative functions), which are excluded from same property results. Additionally, rental revenues from lease 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.

Total market capitalization

Total market capitalization is equal to the sum of total equity market capitalization and total debt. Total equity market capitalization is equal to the sum of outstanding shares of 7.00% Series D cumulative convertible preferred stock and common stock multiplied by the related closing price of each class of security at the end of each period presented.

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 for the three months ended March 31, 2018 and 2017 (dollars in thousands):



	Three Months Ended March 31,
	2018		2017
Unencumbered net operating income	$	198,599	$	157,391
Encumbered net operating income	29,769		36,399
Total net operating income	$	228,368	$	193,790
Unencumbered net operating income as a percentage of total net operating income	87%		81%

110

Weighted-average shares of common stock outstanding – diluted

We enter into capital market transactions from time to time to fund acquisitions, fund construction of our highly leased development and redevelopment projects, and for general working capital purposes. In March 2017 and January 2018, we entered into forward equity sales agreements to sell shares of our common stock. 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.

We also consider the effect of assumed conversions 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. Under the assumed conversion, we add back to net income dividends paid on our Series D Convertible Preferred Stock to the numerator and then include additional common shares assumed to have been issued to the denominator of the per share calculation. On January 1, 2018, we adopted an ASU that requires changes in the fair value of our non-real estate investments to be recognized in net income. Upon adoption of the ASU, we recognized a large unrealized gain in our investment income. As a result of the significant amount of unrealized gain recognized during the three months ended March 31, 2018 , our Series D Convertible Preferred Stock had a dilutive effect on funds from operations attributable to Alexandria Real Estate Equities, Inc.’s common stockholders – diluted, computed in accordance with the definition in the Nareit White Paper. Refer to the “Investments” section within Note 2 – “Summary of Significant Accounting Policies” to these unaudited consolidated financial statements under Item 1 for additional information.

The weighted-average shares of common stock outstanding – diluted during each period include the following shares related to our forward equity sales agreements and Series D cumulative convertible preferred incremental dilutive common stock:



	Three Months Ended March 31,
(In thousands)	2018	2017
Potential additional shares upon conversion/settlement:
Outstanding forward equity sales agreements	6,056	4,755
7.00% Series D Convertible Preferred Stock	2,975	2,975

Incremental dilutive common shares:
Outstanding forward equity sales agreement	270	53
EPS – diluted and funds from operations, as adjusted – diluted	270	53

7.00% Series D Convertible Preferred Stock	741	—
Funds from operations – diluted	1,011	53

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate risk

The primary market risk to which we believe we are exposed is interest rate risk, which may result from many factors, including government monetary and tax policies, domestic and international economic and political considerations, and other factors that are beyond our control.

In order to modify and manage the interest rate characteristics of our outstanding debt and to limit the effects of interest rate risks on our operations, we may utilize a variety of financial instruments, including interest rate swap agreements, caps, floors, and other interest rate exchange contracts. The use of these types of instruments to hedge a portion of our exposure to changes in interest rates carries additional risks, such as counterparty credit risk and the legal enforceability of hedging contracts.

Our future earnings and fair values relating to financial instruments are primarily dependent upon prevalent market rates of interest, such as LIBOR. However, our interest rate hedge agreements are intended to reduce the effects of interest rate fluctuations. The following table illustrates the effect of a 1% change in interest rates, assuming a LIBOR floor of 0%, on our variable-rate debt, including our $1.65 billion unsecured senior line of credit, unsecured senior bank term loans, and secured construction loans, after considering the effect of our interest rate hedge agreements, secured debt, and unsecured senior notes payable as of March 31, 2018 (in thousands):



Annualized effect on future earnings due to variable-rate debt:
Rate increase of 1%	$	(5,756	)
Rate decrease of 1%	$	5,756

Effect on fair value of total consolidated debt and interest rate hedge agreements:
Rate increase of 1%	$	(225,500	)
Rate decrease of 1%	$	242,423

These amounts are determined by considering the effect of the hypothetical interest rates on our borrowing cost and our interest rate hedge agreements in existence on March 31, 2018 . These analyses do not consider the effects of the reduced level of overall economic activity that could exist in such an environment. Further, in the event of a change of such magnitude, we would consider taking actions to further mitigate our exposure to the change. Because of the uncertainty of the specific actions that would be taken and their possible effects, the sensitivity analyses assume no changes in our capital structure.

Equity price risk

We have exposure to equity price market risk because of our equity investments in publicly traded companies and privately held entities. All of our investments in actively traded public companies are reflected in the consolidated balance sheets at fair value. Our investments in privately held entities that report net asset value per share are measured at fair value using NAV as a practical expedient to fair value. Our equity investments in privately held entities that do not report NAV are measured at cost less impairments, adjusted for observable price changes during the period. Changes in fair value for public investments, changes in NAV reported by privately held entities, and observable price changes for privately held entities that do not report NAV are recognized as unrealized gains or losses in our consolidated statements of income. There is no assurance that future declines in value will not have a material adverse effect on our future results of operations. The following table illustrates the effect that a 10% change in the value of our equity investments would have on earnings as of March 31, 2018 (in thousands):



Equity price risk:
Fair value increase of 10%	$	72,431
Fair value decrease of 10%	$	(72,431	)

112

Foreign currency exchange rate risk

We have exposure to foreign currency exchange rate risk related to our subsidiaries operating in Canada and Asia. The functional currencies of our foreign subsidiaries are the respective local currencies. Gains or losses resulting from the translation of our foreign subsidiaries’ balance sheets and statements of income are classified in accumulated other comprehensive income as a separate component of total equity. Gains or losses will be reflected in our consolidated statements of income when there is a sale or partial sale of our investment in these operations or upon a complete or substantially complete liquidation of the investment. The following table illustrates the effect that a 10% change in foreign currency rates relative to the U.S. dollar would have on our potential future earnings and on the fair value of our net investment in foreign subsidiaries based on our current operating assets outside the U.S. as of March 31, 2018 (in thousands):



Effect of potential future earnings due to foreign currency exchange rate:
Rate increase of 10%	$	74
Rate decrease of 10%	$	(74	)

Effect on the fair value of net investment in foreign subsidiaries due to foreign currency exchange rate:
Rate increase of 10%	$	11,035
Rate decrease of 10%	$	(11,035	)

This sensitivity analysis assumes a parallel shift of all foreign currency exchange rates with respect to the U.S. dollar; however, foreign currency exchange rates do not typically move in such a manner, and actual results may differ materially.

Our exposure to market risk elements for the three months ended March 31, 2018 , was consistent with the risk elements presented above, including the effects of changes in interest rates, equity prices, and foreign currency exchange rates.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures

As of March 31, 2018 , we had performed an evaluation, under the supervision of our principal executive officers and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures. These controls and procedures have been designed to ensure that information required for disclosure is recorded, processed, summarized, and reported within the requisite time periods. Based on our evaluation, the principal executive officers and principal financial officer concluded that our disclosure controls and procedures were effective as of March 31, 2018 .

Changes in internal control over financial reporting

There has not been any change in our internal control over financial reporting during the three months ended March 31, 2018 , that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

113

PART II – OTHER INFORMATION

ITEM 1A. RISK FACTORS

In addition to the information set forth in this quarterly report on Form 10‑Q , one should also carefully review and consider the information contained in our other reports and periodic filings that we make with the SEC, including, without limitation, the information contained under the caption “Item 1A. Risk Factors” in our annual report on Form 10‑K for the year ended December 31, 2017 . Those risk factors could materially affect our business, financial condition, and results of operations. The risks that we describe in our public filings are not the only risks that we face. Additional risks and uncertainties not currently known to us, or that we presently deem to be immaterial, also may materially adversely affect our business, financial condition, and results of operations.
