1. Background

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.

Alexandria Real Estate Equities, Inc. (NYSE:ARE), is a self-administered and self-managed investment-grade REIT, and is the largest and leading REIT focused on unique collaborative campuses in urban innovation clusters located in key coastal science and technology gateway cities, with a total market capitalization of $11.3 billion as of March 31, 2015, and an asset base of 30.7 million square feet, including 18.5 million RSF of operating and current value-creation projects, as well as an additional 2.2 million square feet of near-term value-creation development projects and 10.0 million square feet of future ground-up development projects. Alexandria pioneered this niche in 1994 and has since established a dominant market presence in AAA locations, including Greater Boston, the San Francisco Bay Area, New York City, San Diego, Seattle, Maryland, and Research Triangle Park. Alexandria is known for its high-quality and diverse client tenant base, with approximately 52% of its total annualized base rent (“ABR”) (as of March 31, 2015) generated from investment-grade client tenants. Alexandria has a longstanding and proven track record of developing Class A assets clustered in urban science and technology campuses that provide its innovative client 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. We believe these advantages result in higher occupancy levels, longer lease terms, higher rental income, higher returns, and greater long-term asset value. For additional information on Alexandria, please visit our website at www.are.com.

Our asset base consisted of the following, as of March 31, 2015:

	Square Feet
Operating properties	16,620,690
Development properties (includes unconsolidated joint ventures)	1,763,531
Redevelopment properties	143,777
Total operating and current value-creation projects	18,527,998
Near-term value-creation projects (CIP)	2,164,780
Future value-creation projects	9,961,508
	12,126,288
Total	30,654,286

• Investment-grade client tenants represented approximately 52% of our total annualized base rent;

• Approximately 94% 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 indexes;

• Approximately 95% of our leases (on an RSF basis) were triple net leases, requiring client tenants to pay substantially all real estate taxes, insurance, utilities, common area, and other operating expenses (including increases thereto) in addition to base rent; and

• Approximately 93% of our leases (on an RSF basis) provided for the recapture of certain 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.

Any references to the number of buildings, square footage, number of leases, occupancy, and any amounts derived from these values in the notes to the consolidated financial statements are unaudited and outside the scope of our independent registered public accounting firm’s review of our interim consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board.

10

2. Basis of presentation and summary of significant accounting policies

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 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, 2015.  These consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in our annual report on Form 10-K for the year ended December 31, 2014.

Basis of presentation and consolidation

The accompanying 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.

In certain circumstances, we may enter into joint venture arrangements with outside partners. On a quarterly basis, we evaluate each joint venture arrangement under the VIE model, and if the entity is determined not to be a VIE, then we evaluate the entity under the voting model to determine if the entity should be consolidated.

Under the VIE model, an entity is determined to be a VIE if it has any of the following characteristics:

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

• The equity holders, as a group, lack the characteristics of a controlling financial interest; or

• The legal entity is established with non-substantive voting rights.

If an entity is determined to be a VIE, we evaluate whether or not we are the primary beneficiary using qualitative analyses. Factors considered include, but are not limited to, the purpose and design of the VIE, risks that the VIE was designed to create and pass through, the form of our ownership interest, our representation on the entity’s governing body, the size and seniority of our investment, our ability to participate in policy-making decisions, and the rights of the other investors to participate in the decision-making process and/or liquidate the venture, if applicable. We consolidate VIEs whenever we determine that we are the primary beneficiary.

If an entity is determined not to be a VIE, we then evaluate such entity under the voting model. Under the voting model, if we are the general partner or managing member, or have a similar role that can direct the operations of the entity, we have a presumption that we control the entity and we should consolidate regardless of our ownership percentage. If we determine that the other equity holders have any one of the following rights, it is assumed that we do not control the entity and therefore should not consolidate the entity: (i) the substantive ability to dissolve the entity or remove us from the lead role of the entity, or (ii) substantive rights that allow them to participate in the activities that most significantly impact the entity’s economic performance.

As of March 31, 2015, we had two joint ventures that did not meet the requirements for consolidation and were accounted for under the equity method of accounting. Refer to Note 3 – “Investments in Real Estate,” appearing elsewhere in this quarterly report on Form 10-Q, for further information on our unconsolidated joint ventures.

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.

2. Basis of presentation and summary of significant accounting policies (continued)

Investments in real estate and properties classified as “held for sale”

We recognize real estate acquired (including the intangible value of above or below market leases, acquired in-place leases, client tenant relationships, and other intangible assets or liabilities), liabilities assumed, and any noncontrolling interest in an acquired entity at their fair value as of the acquisition date.  If there is a bargain fixed-rate renewal option for the period beyond the non-cancelable lease term of an in-place lease, 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 the property 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 purchase option will be exercised, we consider its impact 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, considering 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.  We also recognize the fair values of assets acquired, the liabilities assumed, and any noncontrolling interest in acquisitions of less than a 100% interest when the acquisition constitutes a change in control of the acquired entity.  Acquisition-related costs related to the acquisition of businesses, including real estate acquired with in-place leases, are expensed as incurred.

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 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 an increase (for below market leases) or a decrease (for above market leases) to rental income. 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.

We are required to capitalize project costs, including predevelopment costs, interest, property taxes, insurance, and other costs directly related and essential to the acquisition, development, redevelopment, predevelopment, or construction of a project.  Capitalization of development, redevelopment, predevelopment, and construction costs is required while activities are ongoing to prepare an asset for its intended use.  Fluctuations in our development, redevelopment, predevelopment, 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, predevelopment, 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.

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.” Prior to our adoption of the new discontinued operations standard on October 1, 2014, the operations of properties “held for sale” were classified as discontinued operations in our consolidated statements of income, and amounts for all prior periods presented were reclassified from continuing operations to discontinued operations.

Subsequent to the adoption of the new standard, if the disposal of the 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 geographical area, (iii) a major equity method investment, or (iv) other major parts of an entity, then the operations of the property “held for sale,” 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 discontinued operations.

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 amount of a long-lived asset may not be recoverable.  The 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, and land held for development, are assessed by project and include significant fluctuations in estimated rental revenues less rental operating expenses, 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 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.”

Investments

We hold equity investments in certain publicly traded companies and investments in certain privately held entities primarily involved in the science industry.  All of our investments in actively traded public companies are considered “available for sale” and are reflected in the accompanying consolidated balance sheets at fair value.  Fair value has been determined based upon the closing price as of each balance sheet date, with unrealized gains and losses shown as a separate component of comprehensive income.  The classification of each investment is determined at the time each investment is made, and such determination is reevaluated at each balance sheet date.  The cost of each investment sold is determined by the specific identification method, with realized gains or losses classified in other income in the accompanying consolidated statements of income.  Investments in privately held entities are generally accounted for under the cost method when our interest in the entity is so minor that we have virtually no influence over the entity’s operating and financial policies. Certain investments in privately held entities are 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 recognize our investment initially at cost and adjust the amount of the investment to recognize our share of the earnings or losses of the investee subsequent to the date of our investment.  Additionally, we limit our ownership percentage in the voting stock of each individual entity to less than 10%.  As of March 31, 2015, and December 31, 2014, our ownership percentage in the voting stock of each individual entity was less than 10%.

We monitor each of our equity investments throughout the year for new developments, including operating results, results of clinical trials, capital-raising events, and merger and acquisition activities. Individual investments are evaluated for impairment when changes in conditions may indicate an impairment exists.  The factors that we consider in making these assessments include, but are 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 there are no identified events or changes in circumstances that might have an adverse effect on our cost method investments, we do not estimate the investment’s fair value.  For all of our investments, if a decline in the fair value of an investment below the carrying value is determined to be other than temporary, such investment is written down to its estimated fair value with a charge to current earnings.

Recognition of rental income and tenant recoveries

Rental income from leases is recognized on a straight-line basis over the respective lease terms.  We classify amounts currently recognized as income, and expected to be received in later years, as deferred rent in the accompanying consolidated balance sheets.  Amounts received currently, but recognized as income 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 income at the date the property is ready for its intended use and the client tenant takes possession of or controls the physical use of the property.

13

2. Basis of presentation and summary of significant accounting policies (continued)

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.

Tenant receivables consist primarily of amounts due for contractual lease payments, reimbursements of common area maintenance expenses, property taxes, and other expenses recoverable from client tenants.  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 client tenants to make payments required under the terms of the lease and for tenant recoveries due.  If a client 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, 2015, and December 31, 2014, we had no allowance for uncollectible tenant receivables and deferred rent.

Monitoring client tenant credit quality

During the term of each lease, we monitor the credit quality of our client tenants by (i) reviewing the credit rating of client tenants that are rated by a nationally recognized credit rating agency, (ii) reviewing financial statements of the client 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 client tenants and their respective businesses, and (iv) monitoring the timeliness of lease payments. We have a team of employees who, among them, have graduate and undergraduate degrees in biology, chemistry, and industrial biotechnology and experience in the science and technology industries, as well as in finance. Our research team is responsible for assessing and monitoring the credit quality of our client tenants and any material changes in credit quality.

Interest and other income

Interest and other income was $485 thousand and $862 thousand during the three months ended March 31, 2015 and 2014, respectively. Interest income is included in other income in the accompanying consolidated statements of income.

Income taxes

We are organized and qualify 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 shareholders annually and meets certain other conditions is not subject to federal income taxes, but could be subject to certain 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, 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 calendar years 2010 through 2013.

Recent accounting pronouncements

In February 2015, the FASB issued an Accounting Standards Update that requires reporting entities to evaluate whether they should consolidate certain legal entities. The Accounting Standards Update modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities and eliminates the presumption that a general partner should consolidate a limited partnership. This Accounting Standards Update affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. The Accounting Standards Update is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. A reporting entity may apply the amendments in the Accounting Standards Update using: (i) a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption; or (ii) by applying the amendments retrospectively. We are currently assessing the potential impact that the adoption of the Accounting Standards Update will have on our consolidated financial statements.

In April 2015, the FASB issued an Accounting Standards Update that requires reporting entities to present debt issuance costs as a direct deduction from the face amount of that note payable presented in the balance sheet. The Accounting Standards Update is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. A reporting entity is required to apply the amendments in the Accounting Standards Update retrospectively to all prior periods. We are currently assessing the potential impact that the adoption of the Accounting Standards Update will have on our consolidated financial statements.

Acquisitions

During the three months ended March 31, 2015, we acquired 640 Memorial Drive located in our Cambridge submarket, for $176.5 million. This property is a 225,504 RSF Class A, LEED^® Gold certified, office/laboratory building located in mid-Cambridge, near the Massachusetts Institute of Technology campus, and is 100% leased to two high-quality life science client tenants pursuant to long-term leases. In connection with the acquisition, we assumed a secured note payable of $82.0 million with a contractual interest rate of 3.93% and a maturity date in 2023. The property is also subject to a long-term ground lease.

Sales of real estate assets and related impairment charges

During the three months ended March 31, 2015, we completed the sale of our land and land improvements at 661 University Avenue in Toronto, Canada, for $54.1 million. Also, during the three months ended March 31, 2015, we sold a 21,859 RSF rental property located in Pennsylvania for $1.9 million. The sales price less cost to sell for each of the dispositions approximated their carrying value at December 31, 2014, and resulted in no gain or loss on sale.

During the three months ended December 31, 2014, we completed the development of the core and shell for a 175,000 RSF building in Hyderabad, India. Also during this time, we evaluated an offer from an Indian multispecialty healthcare provider to acquire the building in its current condition, subject to a successful permitting to allow for hospital or patient-care use. This entity intended to operate the asset as a hospital or a patient-care facility, requiring additional government permits to complete the building construction, which significantly limited the likelihood that this entity would acquire the building. We intended to complete the development and lease the building if we failed to reach reasonable sale terms with this entity. As a result, we completed a probability-weighted cash flow analysis for this building, inclusive of the estimated costs to complete, and determined that the estimated undiscounted cash flows exceeded the carrying amount of the building as of December 31, 2014.

In March 2015, we determined that the building in Hyderabad, India met the criteria for classification as “held for sale” including, among others, the following: (i) management committed to sell the real estate and executed a purchase and sale agreement on March 23, 2015, and (ii) management determined that the sale was probable within one year. Upon classification as “held for sale,” we recognized an impairment charge of $14.5 million to lower the carrying costs of the real estate to its estimated fair value less cost to sell, including an estimated $4.2 million foreign exchange loss. On March 26, 2015, we completed the sale of the building to the Indian multi-specialty healthcare provider for $12.4 million.

As a result of our sales in Canada and India discussed above, we realized an aggregate $9.2 million of losses related to foreign currency translation that were previously classified in accumulated other comprehensive income (loss) on our accompanying consolidated balance sheets.

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 a probability-weighted approach if multiple outcomes are under consideration.

Current value-creation development and redevelopment projects

As of March 31, 2015, we had seven ground-up development projects in process in North America aggregating 1.8 million RSF, including two unconsolidated joint venture development projects. We also had two projects undergoing redevelopment in North America aggregating 143,777 RSF.

Investments in unconsolidated joint ventures

Refer to our consolidation policy described in Note 2 – “Basis of Presentation and Summary of Significant Accounting Policies.”

360 Longwood Avenue

We are currently developing a building aggregating 413,536 RSF in the Longwood Medical Area of the Greater Boston market through an unconsolidated joint venture. The cost at completion for this unconsolidated joint venture real estate project is approximately $350.0 million. As of March 31, 2015, the project was 38% occupied, primarily by Dana-Farber Cancer Institute, Inc. We currently have an additional 103,752 RSF, or 25% of the property, under lease negotiation and expect to reach stabilized occupancy at this property by 2016. The joint venture has a secured construction loan with commitments aggregating $213.2 million, with $166.5 million outstanding as of March 31, 2015. The remaining cost to complete the development is expected to be funded primarily from the remaining commitments of $46.7 million under the secured construction loan. The secured construction loan bears interest at LIBOR+3.75%, with a floor of 5.25%. The maturity date of of the loan is April 1, 2017, with two one-year options to extend the stated maturity date to April 1, 2019, subject to certain conditions.

16

3. Investments in real estate (continued)

We have a 27.5% interest in this unconsolidated joint venture that we account for under the equity method of accounting. Our investment under the equity method of accounting was $49.2 million as of March 31, 2015, and is classified in investments in real estate in our accompanying consolidated balance sheets.

1455/1515 Third Street

In September 2014, Alexandria and Uber Technologies, Inc. (“Uber”) entered into a joint venture agreement and acquired two land parcels supporting the development of two buildings aggregating 422,980 RSF at 1455/1515 Third Street in the Mission Bay submarket of the San Francisco Bay Area market for a total purchase price of $125.0 million. We have a 51% interest and Uber has a 49% interest in this unconsolidated joint venture. The purchase price was funded by contributions into the joint venture by Uber and us. We account for our investment in this joint venture under the equity method of accounting. Our investment under the equity method of accounting was $70.8 million as of March 31, 2015, and is classified in investments in real estate in our accompanying consolidated balance sheets. The project is expected to be funded by equity contributions from Uber and us. We may also fund a portion of the project with proceeds from a secured construction loan. The project is 100% leased to Uber for a 15-year term, commencing upon completion of development.

Near-term value-creation projects in North America (CIP)

Land undergoing predevelopment activities is classified as CIP and is undergoing activities prior to commencement of construction of aboveground building improvements.  We generally will not commence ground-up development of any parcels without first securing pre-leasing for such space, except when there is solid market demand.  If aboveground construction is not initiated at completion of predevelopment activities, the land parcel will be classified as future value-creation projects.  Our objective with predevelopment is to reduce the time it takes to deliver projects to prospective client tenants.  Additionally, during predevelopment, we focus on the design of cost-effective buildings with generic and reusable infrastructure to accommodate single tenancy and multi-tenancy. As of March 31, 2015, we had $227.6 million of land undergoing predevelopment activities in North America aggregating 2.2 million square feet.

Predevelopment costs generally include the following activities prior to commencement of vertical construction:

• Traditional predevelopment costs, including entitlement, design, construction drawings, BIM (3-D virtual modeling), budgeting, sustainability and energy optimization reviews, permitting, and planning for all aspects of the project; and

• Site and infrastructure construction costs, including belowground site work, utility connections, land grading, drainage, egress and regress access points, foundation, and other costs to prepare the site for construction of aboveground building improvements.

Future value-creation projects

Future value-creation projects represent land that we plan to develop in the future, but for which, as of each period presented, no construction or predevelopment activities were ongoing. As a result, interest, property taxes, insurance, and other costs are expensed as incurred. As of March 31, 2015, we had $270.3 million of land held for future development supporting an aggregate of 10.0 million square feet of ground-up development.

4. Investments

We hold investments in certain publicly traded companies and privately held entities involved primarily in the science industry.  Our investments in privately held entities are primarily accounted for under the cost method. Our investments in publicly traded companies are principally marketable equity securities which are accounted for as “available for sale” securities that are carried at their fair values.  Investments in “available for sale” securities with gross unrealized losses as of March 31, 2015, had been in a continuous unrealized loss position for less than 12 months. We have the ability and intent to hold these investments for a reasonable period of time sufficient for the recovery of our investment. We believe that these unrealized losses are temporary and accordingly there are no other-than-temporary impairments in accumulated other comprehensive income related to “available for sale” securities as of March 31, 2015, or December 31, 2014.

The following table summarizes our investments as of March 31, 2015, and December 31, 2014 (in thousands):

	March 31, 2015			December 31, 2014
“Available-for-sale” marketable equity securities, cost basis	$	33,851		$	21,898
Unrealized gains	83,513			53,625
Unrealized losses	(1,608		)	(1,258		)
“Available-for-sale” marketable equity securities, at fair value	115,756			74,265
Investments accounted for under cost method	167,306			162,124
Total investments	$	283,062		$	236,389

The following table outlines our investment income, which is classified in other income in the accompanying consolidated statements of income (in thousands):

	Three Months Ended March 31,
	2015			2014
Investment gains	$	5,937		$	4,040
Investment losses	(2,225		)	(1,694		)
Investment income	$	3,712		$	2,346

5. Fair value measurements

We are required to disclose fair value information about all financial instruments, whether or not recognized in the balance sheet, 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 that are observable at commonly quoted intervals.  “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, 2015 and 2014.

5. Fair value measurements (continued)

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, 2015, and December 31, 2014 (in thousands):

			March 31, 2015
Description	Total		Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs
Assets:
“Available-for-sale” securities	$	115,756	$	115,756	$	—	$	—
Liabilities:
Interest rate swap agreements	$	3,417	$	—	$	3,417	$	—

			December 31, 2014
Description	Total		Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs
Assets:
“Available-for-sale” securities	$	74,265	$	74,265	$	—	$	—
Liabilities:
Interest rate swap agreements	$	909	$	—	$	909	$	—

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.  Our “available-for-sale” marketable equity securities and our interest rate swap agreements, respectively, have been recognized at fair value.  Refer to Note 7 – “Interest Rate Swap Agreements,” for further details on our interest rate swap agreements. The fair values of our secured notes payable, unsecured senior notes payable, unsecured senior line of credit, and unsecured senior bank term loans were estimated using widely-accepted valuation techniques, including discounted cash flow analyses of “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, 2015, and December 31, 2014, the book and estimated fair values of our marketable equity securities, interest rate swap agreements, 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, 2015				December 31, 2014
	Book Value		Fair Value		Book Value		Fair Value

7. Interest rate swap agreements

We use interest rate swap agreements to hedge the variable cash flows associated with certain of our existing LIBOR-based variable-rate debt, including our unsecured senior line of credit and unsecured senior bank term loans.  The ineffective portion of the change in fair value of our interest rate swap agreements is required to be recognized directly in earnings.  During the three months ended March 31, 2015 and 2014, our interest rate swap agreements were 100% effective; because of this, no hedge ineffectiveness was recognized in earnings.  Changes in fair value, including accrued interest and adjustments for non-performance risk, on the effective portion of our interest rate swap agreements that are designated and that qualify as cash flow hedges are classified in accumulated other comprehensive loss. Amounts classified in accumulated other comprehensive loss 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 $1.3 million in accumulated other comprehensive loss to earnings as an increase to interest expense. As of March 31, 2015, and December 31, 2014, the fair values of our interest rate swap agreements aggregating a liability balance of $3.4 million and $909 thousand, respectively, 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. Under our interest rate swap agreements, we have no collateral posting requirements.

The Company has agreements with certain of its derivative counterparties that contain a provision wherein (i) the Company could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Company’s default on the indebtedness; or (ii) if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. If the Company had breached any of these provisions as of March 31, 2015, it could have been required to settle its obligations under the agreements at their termination value of $3.4 million.

We had the following outstanding interest rate swap agreements that were designated as cash flow hedges of interest rate risk as of March 31, 2015 (dollars in thousands):

		Number of Contracts	Weighted Average Interest Pay Rate (1)	Fair Value as of 3/31/15			Notional Amount in Effect as of
Effective Date	Maturity Date						3/31/15		12/31/15		12/31/16

Total				$	(3,417	)	$	950,000	$	950,000	$	600,000

(1) In addition to the interest pay rate for each swap agreement, interest is payable at an applicable margin for borrowings outstanding as of March 31, 2015. Borrowings under our unsecured senior bank term loans include an applicable margin of 1.20% and borrowings outstanding under our unsecured senior line of credit include an applicable margin of 1.10%.

During April 2015, we executed additional interest rate swap agreements that were designated as cash flow hedges of interest rate risk (dollars in thousands):

		Number of Contracts	Weighted Average Interest Pay Rate (1)	Fair Value as of 3/31/15	Notional Amount in Effect as of
Effective Date	Maturity Date				3/31/15		12/31/15		12/31/16

(1) In addition to the interest pay rate for each swap agreement, interest is payable at an applicable margin for borrowings outstanding as of March 31, 2015. Borrowings under our unsecured senior bank term loans include an applicable margin of 1.20% and borrowings outstanding under our unsecured senior line of credit include an applicable margin of 1.10%.

(1) Our March 31, 2015, balance includes a noncontrolling interest purchase liability related to the $108.3 million acquisition of the outstanding 10% noncontrolling interest in our 1.2 million RSF, flagship campus at Alexandria Technology Square^®. For additional information, refer to Note 11 – “Noncontrolling Interests” to our unaudited consolidated financial statements under Item 1 of this report.

9. Earnings per share

We use income from continuing operations attributable to Alexandria’s common stockholders as the “control number” in determining whether potential common shares are dilutive or antidilutive to EPS.  Pursuant to the presentation and disclosure literature on gains or losses on sales or disposals by REITs and EPS required by the SEC and the FASB, gains or losses on sales or disposals by a REIT that do not qualify as discontinued operations are classified below income from discontinued operations in the consolidated statements of income and included in the numerator for the computation of EPS for income from continuing operations.

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 7% series D cumulative convertible preferred stock (“Series D Convertible Preferred Stock”) is not a participating security, and is not included in the computation of EPS using the two-class method.  Under the two-class method, we allocate net income after preferred stock dividends, 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.  Diluted EPS is computed using the weighted average shares of common stock outstanding determined for the basic EPS computation plus the effect of any dilutive securities. We had no dilutive securities outstanding during the three months ended March 31, 2015 and 2014.

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, 2015 and 2014 (in thousands, except per share amounts):

	Three Months Ended March 31,
	2015			2014
Income from continuing operations	$	25,051		$	40,911
Dividends on preferred stock	(6,247		)	(6,471		)

10. Stockholders’ equity

Dividends

In March 2015, we declared cash dividends on our common stock for the first quarter of 2015, aggregating $53.3 million, or $0.74 per share.  Also in March 2015, we also declared cash dividends on our Series D Convertible Preferred Stock for the first quarter of 2015, aggregating approximately $4.2 million, or $0.4375 per share.  Additionally, we declared cash dividends on our Series E cumulative redeemable preferred stock (“Series E Preferred Stock”) for the first quarter of 2015, aggregating approximately $2.1 million, or $0.403125 per share.  In April 2015, we paid the cash dividends on our common stock, Series D Preferred Stock, and Series E Preferred Stock for the first quarter of 2015.

Accumulated other comprehensive loss

Accumulated other comprehensive loss attributable to Alexandria, consists of the following (in thousands):

	Unrealized Gain on Marketable Securities		Unrealized Loss on Interest Rate Swap Agreements			Unrealized Loss on Foreign Currency Translation			Total
Balance as of December 31, 2014	$	52,367	$	(909	)	$	(52,086	)	$	(628	)

Balance as of March 31, 2015	$	81,905	$	(3,417	)	$	(49,275	)	$	29,213

Preferred stock and excess stock authorizations

Our charter authorizes the issuance of up to 100.0 million shares of preferred stock, of which 14.7 million shares were issued and outstanding as of March 31, 2015.  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, 2015.

26

11. Noncontrolling interests

Noncontrolling interests represent the third-party interests in certain entities in which we have a controlling interest.  These entities owned four projects as of March 31, 2015, and are included in our 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.

The following table represents income from continuing operations and discontinued operations attributable to Alexandria Real Estate Equities, Inc., for the three months ended March 31, 2015 and 2014, excluding the amounts attributable to these noncontrolling interests:

	Three Months Ended March 31,
	2015			2014
Income from continuing operations attributable to Alexandria	$	24,559		$	39,716
Loss from discontinued operations	$	(43	)	$	(162	)

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 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.  Distributions, profits, and losses related to these entities are allocated in accordance with the respective operating agreements.  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.

During the three months ended March 31, 2015, we executed an agreement to purchase the outstanding 10% noncontrolling interest in our 1.2 million RSF, flagship campus at Alexandria Technology Square^® for $108.3 million. The first installment of $54.3 million was paid on April 1, 2015, and the second installment of $54.0 million is due on April 1, 2016.

Upon execution of the purchase agreement, we recognized a liability representing the fair value of the aggregate consideration, primarily consisting of the purchase price in the accounts payable, accrued expenses, and tenant security deposits line of our accompanying balance sheet. We measured the fair value of the liability using significant observable inputs including a discount rate that approximates our cost of debt capital in effect during the period the liability is outstanding. The difference between the noncontrolling interest purchase liability and the noncontrolling interest balance of $48.5 million was recognized as a reduction of additional paid-in capital.

12. Discontinued operations/assets classified as “held for sale”

On October 1, 2014, we adopted an Accounting Standards Update on the reporting of discontinued operations that raised the threshold for classification of assets “held for sale” as discontinued operations. This Accounting Standards Update is applied prospectively, and since our adoption of this Accounting Standards Update, no additional properties have met the criteria for classification as a discontinued operation in our consolidated financial statements. Prior to the adoption of this Accounting Standards Update, certain properties met the previous criteria for classification as discontinued operations and are included in the summary of income from discontinued operations below. For additional information, refer to the section titled “Recent Accounting Pronouncements” in Note 2 – “Basis of Presentation and Summary of Significant Accounting Policies” to our unaudited consolidated financial statements under Item 1 of this report.

13. Subsequent events

Amended employment agreement with Mr. Marcus

In April 2015, we amended the employment agreement with Joel S. Marcus to, among other items, extend his term as our Chief Executive Officer (“CEO”) through March 31, 2018.

Key leasing activity

In April 2015, we leased 80,000 RSF to Juno Therapeutics, Inc. (“Juno”), at 400 Dexter Avenue North in our Lake Union submarket in Seattle. Juno has an expansion option for 71,000 RSF. We expect to commence ground-up development of our 287,806 RSF project in 2015, upon receipt of master use plan approval. Also in April 2015, we leased 300,000 RSF, or 100%, to Stripe, Inc. at 510 Townsend Street in our SoMa submarket of the San Francisco Bay Area.

Interest rate swap agreements

We executed additional interest rate swap agreements in March and April 2015, with an aggregate notional amount of $750 million to increase notional hedged variable-rate debt to $950 million during 2015 and a minimum of $800 million during 2016.

14. 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 Company’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, 2015, and December 31, 2014, and the condensed consolidating statements of income, condensed consolidating statements of comprehensive income, and condensed consolidating statements of cash flows for the three months ended March 31, 2015 and 2014, for the Issuer, the Guarantor Subsidiary, and the Combined Non-Guarantor Subsidiaries, as well as the eliminations necessary to arrive at the information for Alexandria Real Estate Equities, Inc., on a consolidated basis, and consolidated amounts. 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.

Overview

We are a Maryland corporation formed in October 1994 that has elected to be taxed as a REIT for federal income tax

purposes. We are a fully integrated, self-administered, and self-managed REIT. We are the largest and leading REIT uniquely focused on collaborative science campuses in urban innovation clusters located in key coastal gateway cities, with a total market capitalization of $11.3 billion as of March 31, 2015, and an asset base of 30.7 million RSF, including 18.5 million RSF of operating and current value-creation projects, as well as an additional 2.2 million square feet of near-term and 10.0 million square feet of future ground-up development projects. Alexandria pioneered this niche in 1994 and has since established a dominant market presence in AAA locations, including Greater Boston, the San Francisco Bay Area, New York City, San Diego, Seattle, Maryland, and Research Triangle Park. Alexandria is known for its high-quality and diverse client tenant base, with approximately 52% of total annualized base rent as of March 31, 2015, generated from investment-grade client tenants – a REIT industry-leading percentage. Alexandria has a longstanding and proven track record of developing Class A assets clustered in urban science and technology campuses that provide its innovative client 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. We believe these advantages result in higher occupancy levels, longer lease terms, higher rental income, higher returns, and greater long-term asset value.

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 assets clustered in urban campuses. These key urban campus locations are characterized by high barriers to entry for new landlords, and a limited supply of available space. They represent highly desirable locations for tenancy by 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, science, and technology relationships in order to identify and attract new and leading client tenants and to source additional value-creation real estate opportunities.

Executive summary

Our results for the first quarter of 2015 highlight both the strength of our operating fundamentals and our unique real estate platform strategy focused on Class A assets in urban innovation cluster campuses located in Greater Boston, the San Francisco Bay Area, New York City, and San Diego. Our growth in FFO and NAV continued into the first quarter of 2015, as we reported FFO per share of $1.28, up 9.4% over the first quarter of 2014. Growth in FFO and cash flows for the quarter was again driven by strong internal growth, including 18.5% cash rental rate increases on lease renewals/re-leasing of space and a 7.8% cash same property NOI increase. Our value-creation pipeline continued to deliver significant earnings and NAV growth with highly leased projects located in collaborative urban innovation campuses. Furthermore, we delivered 494,477 RSF into service, including 388,270 RSF at 75/125 Binney Street in March 2015.  We also commenced the ground-up development at 50/60 Binney Street in our Cambridge submarket, with 98% of the project leased or under negotiation, including 251,234 RSF leased to Sanofi for 97% of 50 Binney Street. Our value-creation deliveries during the quarter decreased our non-income producing assets as a percentage of total assets to 12%.

With our operating properties generating steady growth and our value-creation pipeline producing significant additional growth of NOI, EBITDA, and NAV, we remain confident in our ability to deliver strong results in 2015, while improving our net debt to adjusted EBITDA to less than 7.0 times by year-end.

Development, redevelopment, and future value-creation projects

A key component of our business model is our disciplined allocation of capital to Class A development and redevelopment projects located in highly dynamic and collaborative campuses in key coastal science and technology gateway cities that inspire innovation. These projects are focused on providing high-quality, generic, and reusable space to meet the real estate requirements of, and that are reusable by, a wide range of client tenants. During the period of construction, these assets are non-income-producing assets. A significant number of our active development and redevelopment projects are leased and expected to be substantially delivered in the near term. Upon completion, each value-creation project is expected to generate significant revenues and cash flows. Our development and redevelopment projects are generally in locations that are highly desirable to high-quality science and technology entities, which we believe results in higher occupancy levels, longer lease terms, and higher rental income and returns.

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 Class A office/laboratory or tech office space without first securing significant pre-leasing for such space except when there is solid market demand for high-quality Class A facilities. Predevelopment activities include entitlements, permitting, design, site work, and other activities preceding commencement of construction of aboveground building improvements. The advancement of predevelopment efforts is focused on reducing the time required to deliver projects to prospective client 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.

Our initial stabilized yield is calculated as the quotient of the estimated amounts of NOI upon stabilization and our investment in the property, and excludes the impact of leverage. Our cash rents related to our value-creation projects are expected to increase over time, and our average cash yields are expected, in general, to be greater than our initial stabilized yields (cash basis). 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. Average cash yield reflects cash rents, including contractual rent escalations after initial rental concessions have elapsed, calculated on a straight-line basis. The stabilized occupancy date represents the estimated date on which the project is expected to reach occupancy of 95% or greater.

Non-income-producing assets

The charts below show our current breakdown and our target range of non-income-producing assets as a percentage of our gross investments in real estate, including our share of non-income-producing assets related to our unconsolidated joint ventures.

Overview of value-creation pipeline

A substantial portion of our value-creation pipeline is expected to be delivered in the near term. The completion of these projects is expected to contribute additional operating cash flow and significant growth in NOI and EBITDA. The following table sets forth the expected year in which our current value-creation development and redevelopment projects and our near-term value-creation development projects are forecasted to contribute incremental NOI:

(1) Increase in yields and cost of completion compared to previously disclosed amounts. Previously disclosed estimated yields were 9.1% average cash yield, 8.0% for initial stabilized yield (cash basis), and 8.2% for initial stabilized yield and cost of completion was $351.4 million. The updated information reflects the final terms of our lease with ARIAD Pharmaceuticals, Inc., and excludes an additional $25 per RSF tenant improvement allowance available to the tenant in the future.  If the tenant elects to use this allowance, the total cost at completion could increase up to an additional $10 million with an increase in rental income and an estimated 0.1% increase in our initial stabilized yield from 8.3% to 8.4%.

(2) Consistent with previously disclosed yields.

External growth – acquisitions

The following table presents acquisitions completed during the three months ended March 31, 2015 (dollars in thousands):

													Unlevered

			8		$	284,750		$	82,000		1,407,139

(1) Represents a secured note payable with a contractual rate of 3.93% and a maturity date in 2023.

(2) During the three months ended March 31, 2015, we executed an agreement to purchase the outstanding 10% noncontrolling interest in our 1.2 million RSF, flagship campus at Alexandria Technology Square^® for $108.3 million. Upon execution of the purchase agreement, we recognized a liability representing the fair value of the aggregate consideration, primarily consisting of the $108.3 million purchase price. The first installment of $54.3 million was paid on April 1, 2015, and the second installment of $54.0 million is due on April 1, 2016. For additional information, refer to Note 11 – “Noncontrolling Interests” to our unaudited consolidated financial statements under Item 1 of this report.

(3) We believe there is further upside in our projected returns as we anticipate significant rent growth from 81% of the leases contractually ending in the next five years. Additionally, we believe we can increase our 1.2 million RSF campus by an additional 100,000 RSF and further increase NOI. The campus is currently 99.5% occupied and subject to a long-term ground lease. After considering the $108.3 million purchase of the outstanding 10% noncontrolling interest in this flagship campus and the anticipated near and medium-term upside in NOI from rental rate growth and campus expansion, we estimate that we can enhance our unlevered yields on our aggregate investment in the campus over the next five years to 8.5% and 8.1% (cash).

(1) Annualized using actual results for the quarter ended prior to date of sale or March 31, 2015, for pending and projected asset sales and other assets “held for sale” as of March 31, 2015.

(2) Represents sale price for assets sold, estimated sale price for pending and projected asset sales, and net book value as of March 31, 2015, for other assets “held for sale.”

(3) Represents land and land improvements that were subject to a ground lease prior to the sale with the Company as the lessee. Our annualized net operating loss of $1.4 million primarily represented ground rent expense. Prior to the the completion of the sale in January 2015, our land and land improvements were leased to a client tenant, and the client tenant was completing the construction of a 780,540 RSF building. Rental payments from the client tenant were anticipated to commence in the future upon completion and stabilization of the building.

(4) During the three months ended March 31, 2015, we committed to the sale of a vacant 175,000 RSF building located in Hyderabad, India. Accordingly, we recognized an impairment charge of $14.5 million to reduce the property’s NBV to our estimate of its fair value less cost to sell of $12.4 million. The impairment is primarily related to $7.5 million of increased project costs incurred during a longer-than-anticipated government permitting process to address additional building zoning requirements that arose subsequent to our acquisition of the building, as well as $4.2 million of foreign exchange losses. We estimated that $8.1 million of additional capital expenditures would have been required to complete and lease the building.

(5) Represents estimated 80% (mid-point of range from 70% to 90%) joint venture share of annualized NOI of $13.3 million for the entire property for the three months ended March 31, 2015.

(6) Includes annualized net operating loss of $172 thousand related to one vacant building aggregating 21,940 RSF classified in discontinued operations in our accompanying consolidated statements of income. This is the only property classified in discontinued operations as of March 31, 2015.

Investments in unconsolidated joint ventures

360 Longwood Avenue

We are currently developing a building aggregating 413,536 RSF in the Longwood Medical Area of the Greater Boston market through an unconsolidated joint venture. We expect to earn unlevered yields on our share of the gross real estate in the joint venture as follows: (i) an initial stabilized yield of 8.9%, (ii) an initial stabilized yield (cash basis) of 8.3%, and (iii) average cash yield during the term of the initial leases of 9.3%. Our projected unlevered yields are based upon our share of the investment in real estate of the joint venture at completion of approximately $109.0 million, including costs incurred directly by us outside the joint venture. In addition to these yields, we will receive recurring monthly property management fees thereafter from this project. Construction management and other fees have been excluded from our estimate of unlevered yields. Refer to discussion at Note 3 – “Investments in Real Estate”.

1455/1515 Third Street

Alexandria and Uber entered into a joint venture agreement and acquired two land parcels supporting the development of two buildings aggregating 422,980 RSF at 1455/1515 Third Street in the Mission Bay submarket of the San Francisco Bay Area for a total purchase price of $125.0 million. We are in the process of finalizing the design and construction budget with Uber, and we expect to provide the total estimated cost at completion and estimate of yields in the near future. Refer to discussion at Note 3 – “Investments in Real Estate”.

Rental revenues

Total rental revenues for the three months ended March 31, 2015, increased by $13.0 million, or 10.0%, to $143.6 million, compared to $130.6 million for the three months ended March 31, 2014. The increase was primarily due to rental revenues from our Non-Same Properties, including development and redevelopment projects aggregating 793,788 RSF that were delivered after January 1, 2014, and operating properties aggregating 518,357 RSF that were acquired after January 1, 2014. In addition, rental revenues from our Same Properties for the three months ended March 31, 2015, increased by $1.8 million, or 1.5%, to $125.0 million, from $123.2 million for the three months ended March 31, 2014. Average occupancy of Same Properties increased by 60 bps to 96.0% for the three months ended March 31, 2015, from 95.4% for the three months ended March 31, 2014.

Tenant recoveries

Tenant recoveries for the three months ended March 31, 2015, increased by $6.7 million, or 16.1%, to $48.4 million, compared to $41.7 million for the three months ended March 31, 2014. This increase is consistent with an increase in our rental operating expenses of $8.7 million, or 16.6%. Same Properties tenant recoveries increased by $2.6 million, or 6.4%, primarily as a result of our continued increase in occupancy of Same Properties and an increase in Same Properties rental operating expenses of $1.7 million, or 3.4%. Rental operating expenses increased during the three months ended March 31, 2015, compared to the three months ended March 31, 2014, due to higher repairs and maintenance, and higher utilities, including an increase in heating and snow removal expenses due to a more severe winter in 2015. Non-Same Properties tenant recoveries increased by $4.1 million as a result of a Non-Same Properties rental operating expense increase of $7.0 million.

Other income

Other income for the three months ended March 31, 2015 and 2014, consisted of the following (in thousands):

	Three Months Ended March 31,
	2015		2014		Change
Management fee income	$	554	$	726	$	(172	)
Interest and other income	485		862		(377		)
Investment income	3,712		2,346		1,366
Total other income	$	4,751	$	3,934	$	817

Rental operating expenses

Total rental operating expenses for the three months ended March 31, 2015, increased by $8.7 million, or 16.6%, to $61.2 million, compared to $52.5 million for the three months ended March 31, 2014. Approximately $7.0 million of the increase was due to an increase in rental operating expenses from our Non-Same Properties, primarily related to recently completed development and redevelopment projects, and acquired operating properties as mentioned above. The remaining increase in rental operating expenses of $1.7 million was primarily due to the increase in occupancy and higher utilities and repairs and maintenance as described in “Tenant Recoveries” above.

General and administrative expenses

General and administrative expenses for the three months ended March 31, 2015, increased by $1.2 million, or 8.8%, to $14.4 million, compared to $13.2 million for the three months ended March 31, 2014. General and administrative expenses increased primarily due to higher expenses related to growth in both the depth and breadth of our operations in multiple markets. As a percentage of total assets, our general and administrative expenses were relatively consistent at 0.7% and 0.6% for the trailing 12 months ended March 31, 2015 and 2014, respectively.

67

Interest expense

Interest expense for the three months ended March 31, 2015 and 2014, was as follows (in thousands):

	Three Months Ended March 31,
Component	2015			2014			Change
Secured notes payable	$	7,709		$	7,971		$	(262	)
Unsecured senior notes payable	17,405			11,240			6,165
Unsecured senior line of credit	2,072			2,039			33
Unsecured senior bank term loans	3,341			3,742			(401		)
Interest rate swaps	505			3,490			(2,985		)
Amortization of loan fees and other interest	3,175			2,654			521
Total interest incurred	34,207			31,136			3,071
Capitalized interest	(10,971		)	(12,013		)	1,042
Total interest expense	$	23,236		$	19,123		$	4,113

Total interest expense increased by $4.1 million during the three months ended March 31, 2015, compared to the three months ended March 31, 2014, as a result of a $3.1 million increase in interest incurred and a $1.0 million reduction in the amount of capitalization of interest related to development and redevelopment projects completed subsequent to January 1, 2014, as mentioned above.

The increase of $3.1 million in total interest incurred was primarily due to an increase in our weighted average interest rate from 3.09% as of March 31, 2014, to 3.17% as of March 31, 2015, and an approximate $0.7 billion increase in outstanding debt. Interest from unsecured senior notes payable increased by $6.2 million, offset by a decrease in interest from our secured notes payable, unsecured senior bank term loans, and interest rate swaps by an aggregate $3.6 million, as we continued to transition from variable-rate bank debt to long-term unsecured fixed-rate debt. Interest rate swaps aggregating $200.0 million with rates approximating 5.0% expired on March 31, 2014. In July 2014, we completed an offering of $700 million of unsecured senior notes payable with a weighted average interest rate of 3.50% and maturity of 9.6 years. Proceeds from our July 2014 offering were used to reduce our 2016 unsecured senior bank term loan (“2016 Unsecured Senior Bank Term Loan”) and reduce amounts outstanding under our unsecured senior line of credit.

Depreciation and amortization

Depreciation and amortization for the three months ended March 31, 2015, increased by $8.5 million, or 16.9%, to $58.9 million, compared to $50.4 million for the three months ended March 31, 2014. Depreciation increased primarily due to depreciation related to recently completed development and redevelopment projects, and recently acquired operating properties subsequent to January 1, 2014, as mentioned above.

Impairment of real estate

During the three months ended March 31, 2015, we determined that a 175,000 RSF life science building in Hyderabad, India, met the criteria for classification as “held for sale” and consequently recognized an impairment charge of $14.5 million to lower the carrying costs of the real estate to its estimated fair value less cost to sell, including an estimated $4.2 million foreign exchange loss. On March 26, 2015, we completed the sale of the vacant building for $12.4 million. For additional information, refer to the section titled “Sales of Real Estate Assets and Related Impairment Charges” in Note 3 - “Investments in Real Estate” to our accompanying consolidated financial statements under Item 1 of this report.

Equity in earnings from unconsolidated joint ventures

Equity in earnings of unconsolidated joint ventures of $574 thousand for the three months ended March 31, 2015, includes the results of our ground-up development project at 360 Longwood Avenue in Greater Boston. As of March 31, 2015, we had leased and delivered 157,631 RSF, primarily to our anchor client tenant, the Dana-Farber Cancer Institute, Inc. As of March 31, 2014, 255,905 RSF were still under construction.

68

Loss from discontinued operations

Loss from discontinued operations of $43 thousand and $162 thousand for the three months ended March 31, 2015 and 2014, includes the results of operations of one property that was classified as a discontinued operation as of March 31, 2015, as well as the results of operations (prior to disposition) and gain/loss on sales of real estate attributable to five properties sold subsequent to January 1, 2014.

Projected results

Based on our current view of existing market conditions and certain current assumptions, we have updated guidance for EPS attributable to Alexandria’s common stockholders – diluted and FFO per share attributable to Alexandria’s common stockholders – diluted, each for the year ending December 31, 2015, as set forth in the table below.  The table below provides a reconciliation of FFO per share attributable to Alexandria’s common stockholders – diluted, a non-GAAP measure, to EPS, the most directly comparable GAAP measure, and other key assumptions and key credit metrics included in our guidance for the year ending December 31, 2015.

Summary of Key Changes in Guidance				Description

Net Debt to Adjusted EBITDA	Fixed Charge Coverage Ratio

As of March 31, 2015, we had construction in progress related to our seven North American development projects and two North American redevelopment projects, respectively. The completion of these projects, along with recently delivered projects, certain future projects, and contributions from Same Properties, is expected to contribute significant increases in rental income, NOI, and cash flows. Operating performance assumptions related to the completion of our development and redevelopment projects in North America, including the timing of initial occupancy, stabilization dates, and initial stabilized yield, are included in the “Value-Creation Projects and External Growth” section of this report.Certain key assumptions regarding our projections, including the impact of various development and redevelopment projects, are included in the tables above and in the “Projected Construction Spending” table in the “Summary of Capital Expenditures” subsection of “Value-Creation Projects and External Growth” in this report.

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 these costs will be expensed as incurred. Our projection assumptions for Same Property NOI increase, rental rate increases, straight-line rents, general and administrative expenses, capitalization of interest, interest expense, and key credit metrics are included in the tables above and are subject to a number of variables and uncertainties, including those discussed under the “Forward-Looking Statements” section of Part I, the “Risk Factors” section of Item 1A, and the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section under Item 7, of our annual report on Form 10-K for the year ended December 31, 2014. 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.

Liquidity and capital resources

Overview

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-generating expenditures, and scheduled debt maturities, through net cash provided by operating activities, periodic asset sales, strategic joint venture capital, and long-term secured and unsecured indebtedness, including borrowings under our unsecured senior line of credit, unsecured senior bank term loans, and the issuance of additional debt and/or equity securities.

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 for reinvestment in acquisitions and/or development and redevelopment projects;

• Maintain adequate liquidity from net cash provided by operating activities, cash and cash equivalents, and available borrowing capacity under our unsecured senior line of credit and available commitments under our secured construction loans;

• Reduce the amount of our unsecured bank debt;

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

• Manage the amount of debt maturing in a single year;

• Mitigate unhedged variable-rate debt 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 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;

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

• Maintain solid key credit metrics, including net debt to Adjusted EBITDA and fixed charge coverage ratio, with some variation from quarter to quarter and year to year.

Unsecured senior line of credit and unsecured senior bank term loans

We have unsecured bank debt totaling $1.40 billion as of March 31, 2015, under our 2016 Unsecured Senior Bank Term Loan, 2019 unsecured senior bank term loan (“2019 Unsecured Senior Bank Term Loan”), and amounts outstanding on our $1.5 billion unsecured senior line of credit. The table below reflects the outstanding balances, maturity dates, applicable rates, and facility fees for each of these facilities.

	Balance as of March 31, 2015			As of March 31, 2015
Facility				Maturity Date (1)	Applicable Rate	Facility Fee
2016 Unsecured Senior Bank Term Loan	$	375	million	July 2016 (2)	L+1.20%	N/A
2019 Unsecured Senior Bank Term Loan	$	600	million	January 2019	L+1.20%	N/A
$1.5 billion unsecured senior line of credit	$	421	million	January 2019	L+1.10%	0.20%

(1) Includes any extension options that we control.

(2) We expect to partially repay a portion of this loan and extend the maturity date to 2021.

The maturity date of the unsecured senior line of credit is January 2019, assuming we exercise our sole right to extend the stated maturity date, twice, by an additional six months after each exercise.  Borrowings under the unsecured senior line of credit bear interest at LIBOR or the base rate specified in the amended unsecured senior line of credit agreement, plus in either case a specified margin, (“Applicable Margin”).  The Applicable Margin for LIBOR borrowings under the unsecured senior line of credit is based on our existing credit rating as set by certain rating agencies. Our 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 of LIBOR+1.10%. In addition to the Applicable Margin, our unsecured senior line of credit is subject to an annual facility fee of 0.20% based upon aggregate outstanding commitments.

The requirements of, and our actual performance with respect to, the key financial covenants under our unsecured senior line of credit and unsecured senior bank term loans as of March 31, 2015, were as follows:

Covenant Ratios (1)	Requirement	Actual (2)
Leverage Ratio	Less than or equal to 60.0%	37.4%
Secured Debt Ratio	Less than or equal to 45.0%	7.1%
Fixed Charge Coverage Ratio	Greater than or equal to 1.50x	3.14x
Unsecured Leverage Ratio	Less than or equal to 60.0%	41.8%
Unsecured Interest Coverage Ratio	Greater than or equal to 1.50x	7.84x

(1) For definitions of the ratios, refer to the amended unsecured senior line of credit and unsecured senior bank term loan agreements, each dated as of August 30, 2013, which were filed as exhibits to the Company’s quarterly report on Form 10-Q filed with the SEC on November 7, 2013.

(2) Actual covenants are calculated pursuant to the specific terms to our unsecured senior line of credit and unsecured senior bank term loan agreements.

72

Unsecured senior notes payable

The requirements of, and our actual performance with respect to, the key financial covenants under our 2.75% unsecured senior notes (“2.75% Unsecured Senior Notes”), 3.90% unsecured senior notes (“3.90% Unsecured Senior Notes”), 4.60% unsecured senior notes (“4.60% Unsecured Senior Notes”), and 4.50% unsecured senior notes (“4.50% Unsecured Senior Notes”) as of March 31, 2015, were as follows:

Covenant Ratios (1)	Requirement	Actual
Total Debt to Total Assets	Less than or equal to 60%	42%
Secured Debt to Total Assets	Less than or equal to 40%	8%
Consolidated EBITDA to Interest Expense	Greater than or equal to 1.5x	6.2x
Unencumbered Total Asset Value to Unsecured Debt	Greater than or equal to 150%	233%

(1) For definitions of the ratios, refer to the indenture at Exhibit 4.3 and related supplemental indentures at Exhibits 4.4, 4.7, 4.9, and 4.11, which are each listed in Item 6 of this report.

In addition, the terms of the indentures, among other things, limit the ability of the Company, Alexandria Real Estate Equities, L.P., and the Company’s subsidiaries to (i) consummate a merger, or consolidate or sell all or substantially all of the Company’s assets, and (ii) incur certain secured or unsecured indebtedness.

73

Sources and uses of capital

We expect that our principal liquidity needs for the year ending December 31, 2015, 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.

Key Sources and Uses of Capital (Dollars in thousands)	As of March 31, 2015			2015 Guidance
				Low			High
Sources of capital:
Net cash provided by operating activities after dividends	$	31,000		$	115,000		$	135,000

Incremental debt	$	189,000		$	190,000		$	270,000

(1) See page 61 for discussion on dispositions and other sources of capital.

The key assumptions behind the sources and uses of capital in the table above are 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 under the “Forward-Looking Statements” section of Part I, the “Risk Factors” section of Item 1A, and the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section under Item 7, of our annual report on Form 10-K for the year ended December 31, 2014. We expect to update our forecast of sources and uses of capital on a quarterly basis.

Net cash provided by operating activities after dividends

We expect to retain $115.0 million to $135.0 million of net cash flows from operating activities after payment of common stock and preferred stock dividends. For the year ending December 31, 2015, we expect the completion of our highly pre-leased value-creation projects, along with recently delivered projects, certain future projects, and contributions from Same Properties, to contribute significant increases in rental income, NOI, and cash flows. Refer to the “Cash Flows” section appearing elsewhere in this section of this quarterly report on Form 10-Q for a discussion of net cash provided by operating activities for the three months ended March 31, 2015.

Real estate sales

We continue the disciplined execution of selected sales of land, non-core operating assets, high-value “core-like” operating properties, and joint venture interests in high-value operating properties located in high barrier-to-entry submarkets. 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.

For additional information, refer to the section titled “Sales of Real Estate Assets and Related Impairment Charges” in Note 3 – “Investments in Real Estate” to our unaudited consolidated financial statements under Item 1 of this report and the section titled “Real Estate Asset Sales” in “Value-Creation Projects and External Growth” under Item 2 of this report. The sale of non-strategic

74

non-income-producing-assets and non-core/”core-like” operating assets provides a significant source of capital to fund our highly pre-leased value-creation development and redevelopment projects described above.

Liquidity

The following table presents the availability under our unsecured senior line of credit, secured construction loans, and cash and cash equivalents as of March 31, 2015 (dollars in thousands):

Description	Stated Rate	Total Commitments		Outstanding Balance		Remaining Commitments
$1.5 billion unsecured senior line of credit	LIBOR + 1.10%	$	1,500,000	$	421,000	$	1,079,000

Cash and cash equivalents						90,641
Total						$	1,309,228

Debt

We expect to fund a significant portion of our capital needs in 2015 from the issuance of unsecured senior notes payable, borrowings available under existing secured construction loans, unsecured senior line of credit, new secured construction loans, and acquired secured notes payable.

In July 2014, we completed public offerings of $400 million aggregate principal amount and $300 million aggregate principal amount of unsecured senior notes payable at stated interest rates of 2.75% and 4.50%, respectively, at a weighted average interest rate of 3.50% and a weighted average tenor of 9.6 years. The 2.75% Unsecured Senior Notes were priced at 99.793% of the principal amount with a yield to maturity of 2.791% and are due January 15, 2020. The 4.50% Unsecured Senior Notes were priced at 99.912% of the principal amount with a yield to maturity of 4.508% and are due July 30, 2029. Both the 2.75% Unsecured Senior Notes and the 4.50% Unsecured Senior Notes are unsecured obligations of the Company and are fully and unconditionally guaranteed by Alexandria Real Estate Equities, L.P., a 100% owned subsidiary of the Company. Both the 2.75% Unsecured Senior Notes and the 4.50% Unsecured Senior Notes rank equally in right of payment with all other senior unsecured indebtedness. However, the 2.75% Unsecured Senior Notes and the 4.50% Unsecured Senior Notes are subordinated to existing and future mortgages and other secured indebtedness (to the extent of the value of the collateral securing such indebtedness) and to all existing and future preferred equity and liabilities, whether secured or unsecured, of the Company’s subsidiaries, other than Alexandria Real Estate Equities, L.P. Net proceeds of $694 million from the offering were used to reduce variable-rate debt, consisting of the partial repayment of $125 million of our 2016 Unsecured Senior Bank Term Loan and the reduction of $569 million of borrowings outstanding on our unsecured senior line of credit. In connection with the partial repayment of $125 million of our 2016 Unsecured Senior Bank Term Loan, we recognized a loss on the early extinguishment of debt related to the write-off of unamortized loan fees totaling $525 thousand. We expect to refinance our 2016 Unsecured Senior Bank Term Loan and extend the maturity date to 2021.

Refer to the “Liquidity” section for a discussion of our secured construction loans and unsecured senior line of credit.

Refer to Note 3 – “Investments in Real Estate” to our unaudited consolidated financial statements under Item 1 of this report for a discussion of our acquired debt completed in January 2015 related to 640 Memorial Drive.

Secured construction loans

Refer to Note 6 – “Secured and Unsecured Senior Debt,” to our unaudited consolidated financial statements appearing elsewhere in this quarterly report on Form 10-Q for a discussion of our secured construction loans.

Unsecured senior line of credit

We use our unsecured senior line of credit to fund working capital, construction activities, and, from time to time, acquisition of properties.

Borrowings under the unsecured senior line of credit will bear interest at a “Eurocurrency Rate” or a “Base Rate” specified in the amended unsecured line of credit agreement, plus, in either case, the Applicable Margin. The “Eurocurrency Rate” specified in the amended unsecured line of credit agreement is, as applicable, the rate per annum equal to (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%, (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 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 of LIBOR +1.10%. 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.

Cash and cash equivalents

As of March 31, 2015, and December 31, 2014, we had $90.6 million and $86.0 million, respectively, of cash and cash equivalents.  We expect existing cash and cash equivalents, cash flows from operating activities, proceeds from asset sales, borrowings under our 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, scheduled debt repayments, and certain capital expenditures, including expenditures

related to construction activities.

Restricted cash

Restricted cash consisted of the following as of March 31, 2015, and December 31, 2014 (in thousands):

Uses of capital

Summary of capital expenditures

Our primary use of capital relates to the development, redevelopment, predevelopment, and construction of properties. In North America, we currently have development projects under way for 2,308,726 RSF of office/laboratory and tech office space, including two unconsolidated joint venture development projects. We also have two projects undergoing redevelopment in North America aggregating 167,713 RSF. We incur construction costs related to development, redevelopment, predevelopment, and other construction activities and additional project costs, including interest, property taxes, insurance, and other costs directly related and essential to the development or construction of a project during periods when activities necessary to prepare an asset for its intended use are in progress. Refer to Item 2 – “Summary of Capital Expenditures” 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, 2015 and 2014, of $11.0 million and $12.0 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, and construction projects, aggregating $3.5 million and $4.7 million for the three months ended March 31, 2015 and 2014, respectively. Additionally, 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.  When construction activities cease, the asset is transferred out of construction in progress and classified as rental property.  Also, if vertical aboveground construction is not initiated at completion of predevelopment activities, the land parcel is classified as land held for future development.  Expenditures for repairs and maintenance are expensed as incurred. 

Fluctuations in our development, redevelopment, predevelopment, 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 $1.6 million for the three months ended March 31, 2015.

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 fringe benefits directly related to time spent performing activities previously described and related to the respective lease that would not have been performed but for that lease. Total initial direct leasing costs capitalized during three months ended March 31, 2015 and 2014, were $8.5 million and $8.5 million, respectively, of which $2.8 million and $3.4 million, respectively, represented capitalized and deferred payroll costs directly related and essential to our leasing activities during such periods.

Total	$	5,224,971	$	150,460	$	1,078,681	$	1,229,662	$	2,766,168

(1) Amounts represent principal amounts due and exclude unamortized premiums/discounts reflected on the consolidated balance sheets.

(2) Payment dates include any extension options that we control.

(3) Estimated interest payments on our fixed-rate debt and hedged variable-rate debt are based upon contractual interest rates, including the impact of interest rate swap agreements, interest payment dates, and scheduled maturity dates.

(4) The interest payments on variable-rate debt are based on the interest rates in effect as of March 31, 2015.

Secured notes payable

Secured notes payable as of March 31, 2015, consisted of 14 notes secured by 33 properties. Our secured notes payable typically require monthly payments of principal and interest and had weighted average interest rates of approximately 4.30% as of March 31, 2015. The total book values of rental properties, land held for future development, and construction in progress securing debt were approximately $1.6 billion as of March 31, 2015. As of March 31, 2015, our secured notes payable, including unamortized discounts, were composed of approximately $482.7 million and $277.8 million of fixed and variable-rate debt, respectively.

Estimated interest payments

Estimated interest payments on our fixed-rate debt and hedged variable-rate debt were calculated based upon contractual interest rates, including the impact of interest rate swap agreements, interest payment dates, and scheduled maturity dates. As of March 31, 2015, approximately 81% of our debt was fixed-rate debt or variable-rate debt subject to interest rate swap agreements.  Refer to Note 7 – “Interest Rate Swap Agreements”, to our consolidated financial statements (unaudited) appearing elsewhere in this quarterly report on Form 10-Q for further information. The remaining 19% of our debt as of March 31, 2015, 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, 2015.  Refer to additional information regarding our debt under Note 6 – “Secured and Unsecured Senior Debt”, to our consolidated financial statements (unaudited) appearing elsewhere in this quarterly report on Form 10-Q.

Interest rate swap agreements

We utilize interest rate swap agreements to hedge a portion of our exposure to variable interest rates primarily associated with our unsecured senior line of credit and unsecured senior bank term loans. These 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 our interest rate swap agreements is based on the 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.

78

We have entered into master derivative agreements with each counterparty. 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 counterparties to address and minimize certain risks associated with our interest rate swap agreements. In order to limit our risk

of non-performance by an individual counterparty under our interest rate swap agreements, our interest rate swap agreements are

spread among various counterparties. As of March 31, 2015, the largest aggregate notional amount of the interest rate swap

agreements in effect at any single point in time with an individual counterparty was $250.0 million. If one or more of our

counterparties fail to perform under our interest rate swap agreements, we may incur higher costs associated with our variable-rate

LIBOR-based debt that are higher than the interest costs we originally anticipated. We have not posted any collateral related to our interest rate swap

agreements.

Ground lease obligations

Ground lease obligations as of March 31, 2015, included leases for 28 of our properties, which accounted for approximately 15% of our total number of properties and two land development parcels.  Excluding one ground lease related to one operating property that expires in 2036 with a net book value of $9.9 million as of March 31, 2015, our ground lease obligations have remaining lease terms ranging from 40 to 100 years, including extension options. Refer to Note 12 – “Commitments and Contingencies,” to our consolidated financial statements appearing in the annual report on Form 10-K for further information on our ground leases.

Commitments

As of March 31, 2015, remaining aggregate costs under contract for the construction of properties undergoing development, redevelopment, and improvements under the terms of leases approximated $559.9 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 are also committed to funding approximately $83.2 million for certain investments over the next several years. We have one joint venture with a commitment to contribute our share of equity into this joint venture to complete the project. The additional funding commitment as of March 31, 2015, for this joint venture was pending completion of the final design of the building. Our other joint venture does not have a commitment to contribute additional equity. In addition, we have letters of credit and performance obligations of $11.0 million primarily related to our construction management requirements.

We have minimum development requirements under project development agreements with government entities for some of our future value-creation projects. As of March 31, 2015, we had land and land improvements with an aggregate book value of $23.1 million for which we had construction commitment obligations aggregating approximately 300,000 RSF and 100,000 RSF that need to be fulfilled by 2016 and 2017, respectively. The estimated cost to develop these projects is approximately $125 to $175 per square foot. If we do not meet, extend, or eliminate these commitments, we may default under our existing agreements. The government entities, in turn, have certain obligations to us under those project development agreements. We are working with these entities to fulfill or amend certain existing obligations in a mutually beneficial manner.

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.

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,
	2015			2014			Change
Net cash provided by operating activities	$	106,841		$	73,259		$	33,582
Net cash used in investing activities	$	(170,052	)	$	(162,719	)	$	(7,333	)
Net cash provided by financing activities	$	67,671		$	106,474		$	(38,803	)

Operating activities

Cash flows provided by operating activities for the three months ended March 31, 2015 and 2014, consisted of the following amounts (in thousands):

	Three Months Ended March 31,
	2015			2014		Change
Net cash provided by operating activities	$	106,841		$	73,259	$	33,582
(Less) add: changes in operating assets and liabilities	(16,590		)	8,861		(25,451		)
Net cash provided by operating activities before changes in operating assets and liabilities	$	90,251		$	82,120	$	8,131

Cash flows provided by operating activities are primarily dependent on the occupancy level of our asset base, the rental rates of our leases, the collectability of rent and recovery of operating expenses from our client tenants, the delivery of development projects, the timing and delivery of redevelopment projects, and the timing of acquisitions of operating properties. Net cash provided by operating activities for the three months ended March 31, 2015, increased to $106.8 million, compared to $73.3 million for the three months ended March 31, 2014.  Net cash provided by operating activities before changes in operating assets and liabilities for the three months ended March 31, 2015, increased by $8.1 million, or 9.9%, to $90.3 million, compared to $82.1 million for the three months ended March 31, 2014.  This increase was primarily attributable to an increase in our Same Properties NOI (cash basis) of $8.2 million, or 7.8%, to $113.8 million for the three months ended March 31, 2015, compared to $105.6 million for the three months ended March 31, 2014. In addition, the increase in operating cash flows was attributable to our delivery of development and redevelopment projects aggregating 793,788 RSF that were delivered after January 1, 2014, and operating properties aggregating 518,357 RSF that were acquired in North America after January 1, 2014. These increases were partially offset by the sale of five non-strategic properties aggregating 259,205 RSF over the same period.

Investing activities

Cash flows used in investing activities for the three months ended March 31, 2015 and 2014, consisted of the following (in thousands):

	Three Months Ended March 31,
	2015			2014			Change
Proceeds from sales of real estate	$	67,616		$	—		$	67,616
Additions to real estate	(104,632		)	(111,587		)	6,955
Purchase of real estate	(93,938		)	(42,338		)	(51,600		)
Investment in unconsolidated real estate entities	(2,539		)	(747		)	(1,792		)
Deposits for investing activities	(28,000		)	—			(28,000		)
Other	(8,559		)	(8,047		)	(512		)
Net cash used in investing activities	$	(170,052	)	$	(162,719	)	$	(7,333	)

80

The change in net cash used in investing activities for the three months ended March 31, 2015, is primarily due to a higher use of cash for property acquisitions offset by a higher source of cash from property dispositions and lower capital expenditures incurred on our development and redevelopment projects. The increase in cash used in investing activities was also driven by deposits during the three months ended March 31, 2015, for future acquisitions.

Value-creation opportunities and external growth

For information on our key development and redevelopment projects for the three months ended March 31, 2015, refer to “Development, Redevelopment, and Future Value-Creation Projects” located earlier within Item 2 of this report.

Financing activities

Cash flows provided by financing activities for the three months ended March 31, 2015 and 2014, consisted of the following (in thousands):

	Three Months Ended March 31,
	2015			2014			Change
Borrowings from secured notes payable	$	29,585		$	51,030		$	(21,445	)

Net cash provided by financing activities	$	67,671		$	106,474		$	(38,803	)

Secured construction loans

Refer to Note 6 – “Secured and Unsecured Senior Debt”, to our consolidated financial statements (unaudited) appearing elsewhere in this quarterly report on Form 10-Q for a discussion of our secured construction loans.

Dividends

During the three months ended March 31, 2015 and 2014, we paid the following dividends (in thousands):

	Three Months Ended March 31,
	2015		2014		Change
Common stock dividends	$	53,295	$	48,714	$	4,581
Series D Preferred Stock dividends	4,150		4,375		(225		)
Series E Preferred Stock dividends	2,097		2,096		1
	$	59,542	$	55,185	$	4,357

The increase in dividends paid on our common stock was primarily due to an increase in the related dividends to $0.74 per common share for the three months ended March 31, 2015, from $0.70 per common share for the three months ended March 31, 2014. 

81

Inflation

As of March 31, 2015, approximately 95% of our leases (on an RSF basis) were triple net leases, requiring client 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 94% of our leases (on an RSF basis) contained effective annual rent escalations that were either fixed (generally ranging from 3.0% to 3.5%) or indexed based on a consumer price index or other indexes.  Accordingly, we do not believe that our cash flows or earnings from real estate operations are subject to significant risks from inflation.  An increase in inflation, however, could result in an increase in the cost of our variable-rate borrowings, including borrowings related to our unsecured senior line of credit and unsecured senior bank term loans.

Critical accounting policies

Refer to our annual report on Form 10-K for the year ended December 31, 2014, for a discussion of our critical accounting policies, which include rental properties, net; land held for future development; CIP, discontinued operations; impairment of long-lived assets; capitalization of costs; accounting for investments; interest rate swap agreements; recognition of rental income and tenant recoveries; and monitoring of client tenant credit quality.  There were no significant changes to these policies during the three months ended March 31, 2015.

Non-GAAP measures

FFO and FFO, as adjusted

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 Board of Governors of the NAREIT established the measurement tool of FFO.  Since its introduction, FFO has become a widely used non-GAAP financial measure among equity REITs.  We believe that FFO is helpful to investors as an additional measure of the performance of an equity REIT.  Moreover, we believe that FFO, as adjusted, is also helpful because it allows investors to compare our performance to the performance of other real estate companies on a consistent basis, without having to account for differences caused by investment and disposition decisions, financing decisions, terms of securities, capital structures, and capital market transactions.  We compute FFO in accordance with standards established by the Board of Governors of NAREIT in its April 2002 White Paper and related implementation guidance (“NAREIT White Paper”).  The NAREIT White Paper defines FFO 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 unconsolidated partnerships and joint ventures.  Impairments of real estate relate to decreases in the fair value of real estate due to changes in general market conditions and do not necessarily reflect the operating performance of the properties during the corresponding period.  Impairments of real estate represent the write-down of assets when fair value over the recoverability period is less than the carrying value.  We compute FFO, as adjusted, as FFO calculated in accordance with the NAREIT White Paper, plus losses on early extinguishment of debt, preferred stock redemption charges, impairments of real estate - land parcels, impairments of investments, and the amount of such items that is allocable to our unvested restricted stock awards.  Our calculations of both FFO and FFO, as adjusted, may differ from those methodologies utilized by other equity REITs for similar performance measurements, and, accordingly, may not be comparable to those of other equity REITs.  Our computation of FFO, as adjusted, further adds back impairment write-downs of non-depreciable real estate. Neither FFO nor FFO, as adjusted, should be considered as an alternative to net income (determined in accordance with GAAP) as an indication of financial performance, or to cash flows from operating activities (determined in accordance with GAAP) as a measure of liquidity, nor are they indicative of the availability of funds for our cash needs, including funds available to make distributions.

AFFO

AFFO is a non-GAAP financial measure that we use as a supplemental measure of our performance.  We compute AFFO by adding to or deducting from FFO, as adjusted: (i) non-revenue-enhancing building improvements (excluding amounts recoverable from our client tenants), non-revenue-enhancing tenant improvements and leasing commissions (excluding revenue-enhancing and development and redevelopment expenditures); (ii) effects of straight-line rent revenue and straight-line rent expense on ground leases; (iii) capitalized income from development projects; (iv) amortization of acquired above and below market leases, loan fees, and debt premiums/discounts; (v) stock compensation expense; and (vi) allocation of AFFO attributable to unvested restricted stock awards.

82

We believe that AFFO is a useful supplemental performance measure because it further adjusts FFO to: (i) deduct certain expenditures that, although capitalized and classified in depreciation expense, do not enhance the revenue or cash flows of our properties; (ii) eliminate the effect of straight-lining our rental income and capitalizing income from development projects; and (iii) eliminate the effect of items that are not indicative of our core operations and that do not actually reduce the amount of cash generated by our operations.  We believe that eliminating the effect of charges related to share-based compensation facilitates a comparison of our operations across periods and among other equity REITs without the variances caused by different valuation methodologies, the volatility of the expense (which depends on market forces outside our control), and the assumptions and the variety of award types that a company can use.  We believe that AFFO provides useful information by excluding certain items that are not representative of our core operating results because such items are dependent upon historical costs or subject to judgmental valuation inputs and the timing of our decisions.

AFFO is not intended to represent cash flow for the period, and is intended only to provide an additional measure of performance. We believe that net income attributable to Alexandria’s common stockholders is the GAAP financial measure most comparable to AFFO.  We believe that AFFO is a widely recognized measure of the operations of equity REITs, and presenting AFFO will enable investors to assess our performance in comparison to other equity REITs.  However, other equity REITs may use different methodologies for calculating AFFO and, accordingly, our AFFO may not be comparable to AFFO calculated by other equity REITs.  AFFO should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of financial performance, or to cash flows from operating activities (determined in accordance with GAAP) as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to make distributions.

The following table presents a reconciliation of net income attributable to Alexandria’s common stockholders – basic, the most directly comparable financial measure calculated and presented in accordance with GAAP, to FFO attributable to Alexandria’s common stockholders – basic, FFO attributable to Alexandria’s common stockholders – diluted, as adjusted, and AFFO attributable to Alexandria’s common stockholders – diluted, for the periods below.

Adjusted EBITDA

EBITDA represents earnings before interest, taxes, depreciation, and amortization, a non-GAAP financial measure, and is used by us and others as a supplemental measure of performance.  We use adjusted EBITDA to assess the performance of our core 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 EBITDA, excluding stock compensation expense, gains or losses on early extinguishment of debt, gains or losses on sales of real estate, deal costs, and impairments (“Adjusted EBITDA”). We believe Adjusted EBITDA provides investors relevant and useful information because it permits investors to view income from our operations on an unleveraged basis before the effects of taxes, depreciation and amortization, stock compensation expense, gains or losses on early extinguishment of debt, gains or losses on sales of real estate, and impairments, including our share from our unconsolidated joint ventures.  By excluding interest expense and gains or losses on early extinguishment of debt, EBITDA and Adjusted EBITDA allow investors to measure our performance independent of our capital structure and indebtedness and, therefore, allow for a more meaningful comparison of our performance to that of other companies, both in the real estate industry and in other industries.  We believe that excluding charges related to share-based compensation facilitates a comparison of our operations across periods and among other equity REITs without the variances caused by different valuation methodologies, the volatility of the expense (which depends on market forces outside our control), and the assumptions and the variety of award types that a company can use.  We believe that adjusting for the effects of gains or losses on sales of real estate and land parcels, deal costs, and impairments provides useful information by excluding certain items that are not representative of our core operating results.  These items are dependent upon historical costs, and are subject to judgmental inputs and the timing of our decisions.  EBITDA and Adjusted EBITDA have limitations as measures of our performance.  EBITDA and Adjusted EBITDA do not reflect our historical cash expenditures or future cash requirements for capital expenditures or contractual commitments.  While EBITDA and Adjusted EBITDA are relevant and widely used measures of performance, they do not represent net income or cash flows from operations as defined by GAAP, and they should not be considered as alternatives to those indicators in evaluating performance or liquidity.  Further, our computation of EBITDA and Adjusted EBITDA may not be comparable to similar measures reported by other companies.

Adjusted EBITDA margins

We calculate Adjusted EBITDA margins by dividing Adjusted EBITDA by total revenues. Because our total revenues exclude revenues from discontinued operations, for the purposes of calculating the margin ratio, we exclude the Adjusted EBITDA generated by our discontinued operations for each period presented. We believe excluding Adjusted EBITDA for discontinued operations improves the consistency and comparability of the Adjusted EBITDA margins from period to period. The following table reconciles Adjusted EBITDA to Adjusted EBITDA – excluding discontinued operations (dollars in thousands):

	Three Months Ended				Year Ended
	3/31/15		12/31/14		12/31/14

Fixed charge coverage ratio

The fixed charge coverage ratio is the ratio of Adjusted EBITDA to fixed charges. This ratio is useful to investors as a supplemental measure of our ability to satisfy financing obligations and preferred stock dividends.  Cash interest is equal to interest expense calculated in accordance with GAAP, plus capitalized interest and unconsolidated joint venture cash interest, less amortization of loan fees and amortization of debt premiums/discounts. The fixed charge coverage ratio calculation below is not directly comparable to the computation of “Consolidated Ratio of Earnings to Fixed Charges and 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 for the three months ended March 31, 2015, and on our annual report on Form 10-K, as of December 31, 2014.

The following table presents a reconciliation of interest expense, the most directly comparable GAAP financial measure to cash interest and fixed charges (dollars in thousands):

	Three Months Ended						Year Ended

Net debt to Adjusted EBITDA

Net debt to Adjusted EBITDA is a non-GAAP financial measure that we believe is useful to investors as a supplemental measure in evaluating our balance sheet leverage.  Net debt is equal to the sum of total consolidated debt less cash, cash equivalents, and restricted cash.  Beginning with the three months ended March 31, 2015, our calculation includes our share of unconsolidated joint venture debt and cash. See “Adjusted EBITDA” for further information on the calculation of Adjusted EBITDA.

The following table summarizes the calculation of net debt to Adjusted EBITDA as of March 31, 2015 and 2014 (dollars in thousands):

	As of			As of
	March 31, 2015			December 31, 2014

NOI

NOI is a non-GAAP financial measure equal to income from continuing operations, the most directly comparable GAAP financial measure, excluding loss on early extinguishment of debt, impairment of real estate, depreciation and amortization, interest expense, and general and administrative expense, including our share from our unconsolidated joint ventures.  We believe NOI 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 NOI is a useful measure for evaluating the operating performance of our real estate assets.  NOI on a cash basis is NOI, adjusted to exclude the effect of straight-line rent adjustments required by GAAP.  We believe that NOI on a cash basis is helpful to investors as an additional measure of operating performance because it eliminates straight-line rent adjustments to rental revenue.

87

Further, we believe NOI is useful to investors as a performance measure because when compared across periods, NOI reflects the impact on operations from trends in occupancy rates, rental rates, and operating costs, providing perspective not immediately apparent from income from continuing operations.  NOI can be used to measure the initial stabilized yields of our properties by calculating the quotient of NOI generated by a property on a straight-line basis, and our investment in the property, excluding the impact of leverage. NOI excludes certain components from income from continuing operations 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 operating performance at the property level.  Impairments of real estate have been excluded in deriving NOI 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 the deterioration in market conditions that adversely impact underlying real estate values.  Our calculation of NOI also excludes charges incurred from changes in certain financing decisions, such as losses on early extinguishment of debt, as these charges often relate to the timing of corporate strategy.  Property operating expenses that are included in determining NOI consist of costs that are related to our operating properties, such as utilities, repairs and maintenance; rental expense related to ground leases; contracted services, such as janitorial, engineering, and landscaping; property taxes and insurance; and property-level salaries.  General and administrative expenses consist primarily of accounting and corporate compensation, corporate insurance, professional fees, office rent, and office supplies that are incurred as part of corporate office management.  NOI presented by us may not be comparable to NOI reported by other equity REITs that define NOI differently.  We believe that in order to facilitate a clear understanding of our operating results, NOI should be examined in conjunction with income from continuing operations as presented in our consolidated statements of income.  NOI should not be considered as an alternative to income from continuing operations as an indication of our performance, or as an alternative to cash flows as a measure of liquidity or our ability to make distributions.

Same Properties NOI

See discussion of Same Properties and reconciliation of NOI to income from continuing operations in “Results of Operations.”

Unencumbered NOI as a percentage of total NOI from continuing operations

Unencumbered NOI as a percentage of total NOI from continuing operations 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 primarily reflects those income and expense items that are incurred at the unencumbered property level.  We use unencumbered NOI as a percentage of total NOI from continuing operations, including our share from unconsolidated joint ventures, in order to assess our compliance with our financial covenants under our debt obligations, because the measure serves as a proxy for a financial measure under such debt obligations.  Unencumbered NOI is derived from assets classified in continuing operations, including our share from unconsolidated joint ventures, that are not subject to any mortgage, deed of trust, lien, or other security interest as of the period for which income is presented.  See the reconciliation of NOI to income from continuing operations in “Results of Operations.”

The following table summarizes unencumbered NOI as a percentage of total NOI for the three months ended March 31, 2015 and 2014 (dollars in thousands):

	Three Months Ended March 31,
	2015		2014
Unencumbered NOI	$	111,957	$	103,096
Encumbered NOI	24,433		20,583
Total NOI from continuing operations	$	136,390	$	123,679
Unencumbered NOI as a percentage of total NOI	82%		83%

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 swap agreements are intended to reduce the effects of interest rate changes.  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 unsecured senior line of credit and unsecured senior bank term loans, after considering the effect of our interest rate swap agreements, secured debt, and unsecured senior notes payable as of March 31, 2015 (in thousands):

Annualized impact to future earnings due to variable-rate debt:
Rate increase of 1%	$	(5,493	)
Rate decrease of 1%	$	968
Effect on fair value of total consolidated debt and interest rate swap agreements:
Rate increase of 1%	$	(158,814	)
Rate decrease of 1%	$	157,261

These amounts are determined by considering the impact of the hypothetical interest rates on our borrowing cost and our interest rate swap agreements in existence on March 31, 2015.  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.  However, 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 certain publicly traded companies and privately held entities.  We classify investments in publicly traded companies as “available for sale” and, consequently, recognize them in the accompanying consolidated balance sheets at fair value, with unrealized gains or losses reported as a component of accumulated other comprehensive income (loss).  Investments in privately held entities are generally accounted for under the cost method because we do not influence any of the operating or financial policies of the entities in which we invest.  For all investments, we recognize other-than-temporary declines in value against earnings in the same period during which the decline in value was deemed to have occurred.  There is no assurance that future declines in value will not have a material adverse impact on our future results of operations.  The following table illustrates the effect that a 10% change in the fair value of our equity investments would have on earnings as of March 31, 2015 (in thousands):

Equity price risk:
Fair value increase of 10%	$	28,306
Fair value decrease of 10%	$	(28,306	)

89

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 (loss) as a separate component of total equity.  Gains or losses will be reflected in our 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 the fair value of our net investment in foreign subsidiaries based on our current operating assets outside the U.S. as of March 31, 2015 (in thousands):

Impact of potential future earnings due to foreign currency exchange rate:
Rate increase of 10%	$	(178	)
Rate decrease of 10%	$	178
Effect on the fair value of net investment in foreign subsidiaries due to foreign currency exchange rate:
Rate increase of 10%	$	26,411
Rate decrease of 10%	$	(26,411	)

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, 2015, 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, 2015, we had performed an evaluation, under the supervision of our CEO and Chief Financial Officer (“CFO”), 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 CEO and CFO concluded that our disclosure controls and procedures were effective as of March 31, 2015.

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, 2015, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

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, 2014.  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.
