1. Background

As used in this quarterly report on Form 10-Q, references to the “Company,” “Alexandria,” “we,” “our,” and “us” refer to Alexandria Real Estate Equities, Inc. and its consolidated subsidiaries.

Alexandria Real Estate Equities, Inc. (NYSE:ARE), with a total market capitalization of approximately $9.3 billion as of June 30, 2014, and an asset base of 31.4 million square feet, including 17.9 million rentable square feet (“RSF”) of operating and current value-creation projects, as well as an additional 13.5 million square feet in future ground-up development projects, is the largest and leading real estate investment trust (“REIT”) uniquely focused on Class A assets in collaborative science and technology campuses located in urban innovation clusters. 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, San Diego, New York City, Maryland, Seattle, and Research Triangle Park. Alexandria is known for its high-quality and diverse client tenant base. Alexandria is the Landlord of Choice to the Life Science Industry^®, and approximately 52% of its total annualized base rent (“ABR”) results 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 collaborative science and technology campuses that provide its client tenants with a highly collaborative, 24/7, live/work/play environment, as well as the critical ability to successfully recruit and retain best-in-class talent. 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 June 30, 2014:

	Square Feet
Operating properties	15,804,327
Development properties	1,879,492
Redevelopment properties	197,289
Total operating and current value-creation projects	17,881,108
Near-term value-creation projects in North America (CIP)	2,474,163
Future value-creation projects	10,760,108
Land subject to sale negotiations	262,950
Total	31,378,329

Ÿ Investment-grade client tenants represented approximately 52% of our total ABR;

Ÿ Approximately 96% of our leases (on an RSF basis) contained effective annual rent escalations that were either fixed (generally ranging from 3% to 3.5%) or indexed based on a consumer price index or other index;

Ÿ Approximately 94% 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;

Ÿ Approximately 93% of our leases (on an RSF basis) provided for the recapture of certain capital expenditures (such as heating, ventilation, and air conditioning (“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.

2. Basis of presentation

We have prepared the accompanying interim consolidated financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) and in conformity with the rules and regulations of the Securities and Exchange Commission (“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, 2014.  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, 2013.

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.

We hold interests, together with certain third parties, in companies that we consolidate in our financial statements. We consolidate the companies because we exercise significant control over major decisions by these entities, such as investment activity and changes in financing.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation for discontinued operations.

Use of estimates

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

Investments in real estate, net, and discontinued operations

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, 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.  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 lives 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.

10

2. Basis of presentation (continued)

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 activities 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.  When all of these criteria have been met, the property is classified as “held for sale,” and if (i) the operations and cash flows of the property have been or will be eliminated from the ongoing operations, and (ii) we will not have any significant continuing involvement in the operations of the property after the sale, then its operations, 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.  Depreciation of assets ceases upon designation of a property as “held for sale.”

Impairment of long-lived assets

Long-lived assets to be held and used, including our rental properties, land held for development, construction in progress, 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, land held for development, and construction in progress, are assessed by project and include significant fluctuations in estimated net operating income (“NOI”), 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.”

We hold equity investments in certain publicly traded companies and investments in certain privately held entities primarily involved in the life 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 and limited partnerships 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 and limited partnerships are accounted for under the equity method when our interest in the entity is not deemed 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 interest of each individual entity to less than 10%.  As of June 30, 2014, and December 31, 2013, our ownership percentage in the voting interest of each individual entity was less than 10%.

We monitor each of our investments throughout the year for new developments, including operating results, results of clinical trials, capital-raising events, and merger and acquisition activities. Individual investments 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 would 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.

Income taxes

We are organized and qualify as a REIT pursuant to the Internal Revenue Code of 1986, as amended (the “Code”).  Under the Code, a REIT that distributes 100% of its REIT taxable income as a dividend to its shareholders each year and that meets certain other conditions is not subject to federal income taxes, but could be subject to certain state and local taxes.  We have distributed 100% or more of our taxable income.  Therefore, no provision for federal income taxes is required.  We file tax returns, including returns for our subsidiaries, with federal, state, and local jurisdictions, including jurisdictions located in the United States (“U.S.”), Canada, India, China, and other international locations.  Our tax returns are subject to examination in various jurisdictions for the calendar years 2009 through 2013.

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 an asset in 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.

Tenant recoveries related to reimbursement of real estate taxes, insurance, utilities, repairs and maintenance, 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 rent and deferred rent receivables arising from the straight-lining of rent.  As of June 30, 2014, and December 31, 2013, we had no allowance for estimated losses.

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 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 life science industry, as well as in finance. This research team is responsible for assessing and monitoring the credit quality of our client tenants and any material changes in credit quality.

Interest income

Interest income was $911 thousand and $990 thousand during the three months ended June 30, 2014 and 2013, respectively. Interest income was $1.8 million and $2.3 million during the six months ended June 30, 2014 and 2013, respectively.  Interest income is included in other income in the accompanying consolidated statements of income.

Impact of recently issued accounting standards

In April 2014, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) on the reporting of discontinued operations, which raises the threshold for disposals to qualify as discontinued operations. Under this ASU, a discontinued operation is (i) a component of an entity or group of components that has been disposed of by sale, that has been disposed of other than by sale, or that is classified as “held for sale” and represents a strategic shift that has had or will have a major effect on an entity’s operations and financial results or (ii) an acquired business or nonprofit activity that is classified as “held for sale” on the date of the acquisition. A strategic shift that has or will have a major effect on an entity’s operations and financial results could include the disposal of (i) a major line of business, (ii) a major geographic area, (iii) a major equity method investment, or (iv) other major parts of an entity. Under current GAAP, an entity is prohibited from reporting a discontinued operation if it has certain continuing cash flows or involvement with the component after the disposal. This ASU eliminates these criteria and is effective for public companies during the interim and annual periods, beginning after December 15, 2014. We are required to adopt this ASU no later than January 1, 2015 and may early adopt this ASU during interim periods, as applicable. We expect the adoption of this ASU to result in fewer real estate sales qualifying for classification as discontinued operations in our consolidated financial statements.

In May 2014, the FASB issued an ASU that replaces substantially all industry-specific revenue recognition requirements and converges areas under this topic with International Financial Reporting Standards. The ASU implements a five-step process for customer contract revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards. The ASU also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows from contracts with customers. Other major provisions in this ASU include capitalizing and amortizing certain contract costs, ensuring the time value of money is considered in the applicable transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. The ASU is effective for reporting periods beginning after December 15, 2016, and early adoption is prohibited. The ASU does not apply to lease contracts accounted for under current GAAP. We are currently evaluating the impact of the adoption of this ASU will have on our financial position and results of operations.

Acquisitions

In January 2014, we acquired 3545 Cray Court, a 116,556 RSF laboratory/office property located in the Torrey Pines submarket of San Diego, for $64.0 million. The property was 100% occupied on the date of acquisition. In connection with the acquisition, we assumed a $40.7 million non-recourse secured note payable with a contractual interest rate of 4.66% and a maturity in January 2023.

In March 2014, we acquired 225 Second Avenue, a vacant 112,500 RSF office property located in the Route 128 submarket of Greater Boston, for $16.3 million. In May 2014, we leased 100% of the project to accommodate expansion requirements of an existing tenant. The property is undergoing conversion into laboratory/office space through redevelopment.

In March 2014, we acquired 4025/4031/4045 Sorrento Valley Boulevard, three adjacent buildings aggregating 42,566 RSF located in the Sorrento Valley submarket of San Diego, for a total purchase price of $12.4 million. These properties were 100% occupied on the date of acquisition. In connection with the acquisition, we assumed a $7.6 million non-recourse secured note payable with a contractual interest rate of 5.74% and a maturity in April 2016.

In April 2014, we acquired 500 Townsend Street, a land parcel supporting approximately 300,000 gross square feet, in the South of Market (“SoMa”) submarket of the San Francisco Bay Area for a purchase price of $50.0 million. We are in the process of perfecting entitlements, marketing for lease, and subject to market conditions, we plan to commence construction as soon as possible in 2015.

Current development and redevelopment projects

As of June 30, 2014, we hadsixground-up development projects in process in North America aggregating1.4 millionRSF, including an unconsolidated joint venture development project. We also hadthreeprojects undergoing redevelopment in North America aggregating197,289 RSF.

Investment in unconsolidated real estate entity

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 is approximately $350.0 million. The project is 37% pre-leased to Dana-Farber Cancer Institute, Inc. The joint venture had a construction loan with commitments aggregating $213.2 million with $128.0 million outstanding as of June 30, 2014. The remaining cost to complete the development is expected to be funded primarily from the remaining commitments of $85.2 million under the construction loan. The construction loan bears interest at LIBOR+3.75%, with a floor of 5.25%, and has a maturity date of April 1, 2019, inclusive of two separate one-year options to extend the stated maturity date of April 1, 2017.

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 $48.0 million as of June 30, 2014.

We do not qualify as the primary beneficiary of the unconsolidated joint venture since we do not have the power to direct the activities of the entity that most significantly impact its economic performance. The decisions that most significantly impact the entity’s economic performance require both our consent and that of our partners, including all major operating, investing, and financing decisions, as well as decisions involving major expenditures. Consequently, we do not consolidate this joint venture, and we account for our investment under the equity method of accounting.

Land undergoing predevelopment activities (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 undergoing predevelopment activities without first securing pre-leasing for such space, except when there is significant market demand.  If aboveground construction is not initiated at completion of predevelopment activities, the land parcel will be classified as land held for development.  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 and multi-tenancy. As of June 30, 2014, we held land undergoing predevelopment activities in North America aggregating 2.5 million RSF. The largest project included in land undergoing predevelopment activities consists of substantially all of our 1.1 million square feet at the Alexandria Center™ at Kendall Square located in East Cambridge, Massachusetts.

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

Ÿ 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

Ÿ 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. For example, site and infrastructure costs for the 1.1 million RSF primarily related to 50, 60, and 100 Binney Street of the Alexandria Center™ at Kendall Square are classified as predevelopment prior to commencement of vertical construction.

Land held for development

Land held for development represents real estate 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 June 30, 2014, we had land held for development in North America supporting an aggregate of 3.2 million RSF of ground-up development.

Dispositions

During the six months ended June 30, 2014, we sold a land parcel for consideration of $19.0 million to a buyer expected to reposition the property for multi-family residential use. We recognized a gain of $0.8 million on the sale. This gain is classified in gain on sale of land parcel in the accompanying consolidated statements of income.

4. Investments

We hold investments in certain publicly traded companies and privately held entities, including limited partnerships, involved primarily in life science and related industries.  Our investments in publicly traded companies are accounted for as “available for sale” securities and are carried at their fair values.  Investments in “available for sale” securities with gross unrealized losses as of June 30, 2014, 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 have not recognized other-than-temporary impairments related to “available for sale” securities as of June 30, 2014. As of June 30, 2014, and December 31, 2013, there were no unrealized losses in our investments in privately held entities, including limited partnerships.

The following table summarizes our investments as of June 30, 2014, and December 31, 2013 (in thousands):

	June 30, 2014				December 31, 2013
“Available-for-sale” marketable equity securities, cost basis	$	12,937			$	2,879
Unrealized gains	19,338			(1)	2,177
Unrealized losses	(1,297		)		(587		)
“Available-for-sale” marketable equity securities, at fair value	30,978				4,469
Investments accounted for under cost method	143,824				135,819
Total investments	$	174,802			$	140,288

(1) The increase in our investments during the six months ended June 30, 2014, was primarily related to an increase in unrealized gains of approximately $16.0 million related to our investments in publicly traded life science companies. These unrealized gains are a component of our comprehensive income, within our stockholders’ equity, and have not been recognized in the accompanying consolidated statement of income for the six months ended June 30, 2014.

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

	Three Months Ended June 30,						Six Months Ended June 30,

6. 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 six months ended June 30, 2014 and 2013, 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 $3.1 million in accumulated other comprehensive loss to interest expense as an increase to interest expense. As of June 30, 2014, and December 31, 2013, the fair values of our interest rate swap agreements aggregating an asset balance were classified in other assets, and those aggregating a liability balance were classified in accounts payable, accrued expenses, and tenant security deposits, based upon their respective fair values. Under our interest rate swap agreements, we have no collateral posting requirements.

As of June 30, 2014, the fair value of derivatives in a net liability position was $2.6 million. 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 at June 30, 2014, it could have been required to settle its obligations under the agreements at their termination value of $2.6 million.

We had the following outstanding interest rate swap agreements that were designated as cash flow hedges of interest rate risk as of June 30, 2014 (dollars in thousands):

Effective Date	Maturity Date	Number of Contracts	Weighted Average Interest Pay Rate (1)	Fair Value as of 6/30/14			Notional Amount in Effect as of

(1) In addition to the interest pay rate, borrowings outstanding as of June 30, 2014, 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%.

7. 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 and six months ended June 30, 2014 and 2013.

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 June 30, 2014, and December 31, 2013 (in thousands):

			June 30, 2014
Description	Total		Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs
Assets:
“Available-for-sale” securities	$	30,978	$	30,978	$	—	$	—
Interest rate swap agreements	$	46	$	—	$	46	$	—
Liabilities:
Interest rate swap agreements	$	2,668	$	—	$	2,668	$	—

			December 31, 2013

Interest rate swap agreements	$	2,870	$	—	$	2,870	$	—
Liabilities:
Interest rate swap agreements	$	6,191	$	—	$	6,191	$	—

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” securities and our interest rate swap agreements, respectively, have been recognized at fair value.  See Note 6 – 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.

8. 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 earnings per share.  Pursuant to the presentation and disclosure literature on gains or losses on sales or disposals by REITs and earnings per share 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 earnings per share for income from continuing operations.

The land parcels we sold during the three and six months ended June 30, 2014 and 2013, did not meet the criteria for classification as discontinued operations because the land parcels did not have significant operations prior to disposition.  Accordingly, for the three and six months ended June 30, 2014 and 2013, we classified approximately $797 thousand and $772 thousand, respectively, as gain on sale of land parcel below income from discontinued operations, net, in the accompanying consolidated statements of income, and included the gain in income from continuing operations attributable to Alexandria’s common stockholders in the “control number,” or numerator, for computation of earnings per share.

We account for unvested restricted stock awards that contain nonforfeitable rights to dividends as participating securities and include these securities in the computation of earnings per share using the two-class method.  Our Series D cumulative convertible preferred stock (“Series D Preferred Stock”) is not a participating security, and is not included in the computation of earnings per share 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 earnings per share is computed using the weighted average shares of common stock outstanding determined for the basic earnings per share computation plus the effect of any dilutive securities, including the dilutive effect of stock options using the treasury stock method, during the period the securities were outstanding.

Earnings per share – basic and diluted	$	0.39		$	0.38		$	0.85		$	0.74

For purposes of calculating diluted earnings per share, we did not assume conversion of our Series D Preferred Stock for the three and six months ended June 30, 2014 and 2013, since the impact was antidilutive to earnings per share attributable to Alexandria’s common stockholders from continuing operations during those periods.

Preferred stock and excess stock authorizations

Our charter authorizes the issuance of up to 100.0 million shares of preferred stock, of which 15.2 million shares were issued and outstanding as of June 30, 2014.  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 June 30, 2014.

11. Noncontrolling interests

Noncontrolling interests represent the third-party interests in certain entities in which we have a controlling interest.  These entities owned 10 properties and three development parcels as of June 30, 2014, 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.

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.  As of June 30, 2014, and December 31, 2013, our redeemable noncontrolling interest balances were $14.4 million and $14.4 million, respectively.  Our remaining noncontrolling interests, aggregating $67.7 million and $47.7 million as of June 30, 2014, and December 31, 2013, respectively, do not have rights to require us to purchase their ownership interests and are classified in total equity in the accompanying consolidated balance sheets.

Net proceeds of $694 million were used to repay $125 million of our 2016 unsecured senior bank term loan (“2016 Unsecured Senior Bank Term Loan”) and $569 million of the amounts 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 $0.5 million.

Alexandria Real Estate Equities, Inc. (the “Issuer”) has sold certain debt securities registered under the Securities Act, 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.

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

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

• Industrial factors such as adverse developments concerning the life science industry and/or our life science client tenants;

• Governmental factors such as any unfavorable effects resulting from U.S., state, local and/or foreign government policies, laws, and/or funding levels;

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

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

This list of risks and uncertainties is not exhaustive. Additional information regarding risk factors that may affect us is included under “Item 1A. Risk Factors” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our annual report on Form 10-K for the fiscal year ended December 31, 2013.  Readers of this quarterly report on Form 10-Q should also read our other documents filed publicly with the SEC for further discussion regarding such factors.

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 the largest and leading REIT uniquely focused on Class A collaborative science and technology campuses in urban innovation clusters, with a total market capitalization of approximately $9.3 billion as of June 30, 2014, and an asset base of 31.4 million square feet, including 17.9 million RSF of operating and current value-creation projects, as well as an additional 13.5 million square feet in future ground-up development projects. We pioneered this niche in 1994 and have since established a dominant market presence in AAA locations including Greater Boston, the San Francisco Bay Area, San Diego, New York City, Maryland, Seattle, and Research Triangle Park. We are known for our high-quality and diverse client tenant base, and approximately 52% of our total ABR results from investment-grade client tenants (a REIT industry-leading percentage). We have a longstanding and proven track record of developing Class A assets clustered in urban science and technology campuses that provide client tenants with highly collaborative, 24/7, live/work/play ecosystems, as well as the critical ability to successfully recruit and retain best-in-class talent and enhance productivity. We believe these advantages result in higher occupancy levels, longer lease terms, higher rental income, higher returns, and greater long-term asset value.

Executive summary

We remain focused on our goal to provide stable and consistent funds from operations (“FFO”) per share and net asset value growth driven by strong core performance and healthy demand for our active and near-term value-creation pipeline.  Our performance thus far in 2014 has been solid and we anticipate solid results for the remainder of the year.  We remain committed to our goal of funding our 2014 capital needs with earnings before interest, taxes, depreciation, and amortization (“EBITDA”) growth and sales of land parcels. Cash flows from operating activities after dividends and a significant increase in EBITDA is forecasted to provide significant capacity in 2015 to fund our growth, including construction, while maintaining our target net debt to adjusted EBITDA of 6.5x in 2015.

External growth: value-creation projects and acquisitions

Value-creation projects

• 79% of our development and redevelopment projects aggregating 1,934,431 RSF in North America are leased or under lease negotiations

• Key deliveries during the three months ended June 30, 2014, from our value-creation projects included the following:

• 72,216 RSF to Illumina, Inc. at 499 Illinois Street in our Mission Bay submarket

• 37,943 RSF to several tenants at 430 East 29th Street, the Alexandria Center^TM for Life Science, in our Manhattan submarket

42

• During the three months ended June 30, 2014, we commenced development of 3013/3033 Science Park Road, a 165,938 RSF project in the Torrey Pines submarket of San Diego. This development project is currently 63% leased/under negotiation, including 25% pre-leased to a publicly traded life science company. Our ability to preserve the existing steel frame in a section of the project will allow us to reduce the time to deliver a portion of the project for initial occupancy in early 2015.

• Delivery of high value pre-leased development and redevelopment projects will drive significant increases in EBITDA, cash flows, net asset value, and per share earnings. Additionally, deliveries over the next few quarters will drive non-income-producing assets (CIP and land) to 12% of gross real estate by the first quarter of 2015.

Acquisitions

• In April 2014, we acquired a land parcel at 500 Townsend Street, supporting the ground-up development of approximately 300,000 gross square feet, in the SoMa submarket of the San Francisco Bay Area for a purchase price of $50.0 million. We are in the process of perfecting entitlements and marketing for lease. Subject to market conditions, we plan to commence construction as soon as possible in 2015.

Dispositions of land parcels

• In May 2014, we completed the sale of a land parcel at 810 Dexter Avenue North in the Seattle market for a sales price of $19.0 million and a gain of $797 thousand. The buyer is expected to reposition the property for multi-family residential use.

• In July 2014, we completed the sale of two land parcels in a non-cluster market for a sales price of $7.9 million and a gain of $207 thousand. The buyer is expected to use the land for academic institution purposes.

Balance sheet

• In July 2014, we completed an offering of $700 million aggregate principal amount of unsecured senior notes payable, consisting of the following:

• $400 million of aggregate principal amount of our 2.75% Unsecured Senior Notes

• $300 million of aggregate principal amount of our 4.50% Unsecured Senior Notes

• Weighted average interest rate of 3.50% and maturity of 9.6 years

• Weighted average remaining term of outstanding debt extended from 5.1 years to 6.3 years while prudently laddering debt maturities

• Net proceeds of $694 million 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 $0.5 million, or $0.01 per share.

• Certain statistics as of June 30, 2014, on a pro forma basis for the $700 million unsecured senior notes payable offering completed in July 2014:

• Liquidity of $1.8 billion

• Unhedged variable-rate debt as a percentage of total debt of 7%

• Cash flows from operating activities, after dividends, plus increases in EBITDA in 2015, are expected to provide significant capacity to fund $500 million to $600 million of growth, including construction, in 2015

• Unencumbered NOI as a percentage of total NOI of 84% for the three months ended June 30, 2014

LEED statistics

• In May 2014, our 225 Binney Street property achieved LEED Gold certification.

• In June 2014, our 1201 Eastlake Avenue East achieved LEED Silver Existing Building Operations and Maintenance (“EB O&M”) certification. This building is part of only a handful of labs in the entire world with LEED Silver EB O&M certification.

• As of June 30, 2014, our asset base had 29 LEED certified projects with an additional 27 LEED certifications in process.

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 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 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 life science industry, as well as in finance. This research team is responsible for assessing and monitoring the credit quality of our tenants and any material changes in credit quality.

Value-creation projects and external growth

Development, redevelopment, and future value-creation projects

A key component of our business model is our value-creation development and redevelopment projects. These programs are focused on providing high-quality, generic, and reusable science and technology space to meet the real estate requirements of 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 pre-leased and expected to be substantially delivered over the next six quarters. 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, which we believe results in higher occupancy levels, longer lease terms, and higher rental income and returns.

Development projects generally consist of the ground-up development of generic and reusable facilities. Redevelopment projects generally consist of the permanent change in use of office, warehouse, and shell space into generic science and technology space. We generally will not commence new development projects for aboveground construction of Class A science and technology space without first securing pre-leasing for such space except when there is significant market demand for high-quality Class A facilities. Predevelopment activities include entitlements, permitting, design, site work, and other activities prior to commencement of construction of aboveground building improvements. Our objective also includes the advancement of predevelopment efforts to reduce 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 for the Company. The largest project in our land undergoing predevelopment activities in North America includes 1.1 million RSF at Alexandria Center^TM at Kendall Square in East Cambridge, Massachusetts.

Our initial stabilized yield is calculated as the quotient of the estimated amount of stabilized NOI 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 on a cash basis. Our estimates for initial yields, initial yields on a cash basis, and total costs at completion represent our initial estimates at the commencement of each project. Initial stabilized yield reflects cash rents, 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 on a cash basis reflects rental income less straight-line rent 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.

As of June 30, 2014, we had six ground-up development projects in process in North America, including an unconsolidated joint venture development project, aggregating 1.4 million RSF. We also had three projects undergoing conversion into laboratory/office or tech office space through redevelopment, aggregating 197,289 RSF. These projects, along with recently delivered projects, certain future projects, and contribution from Same Properties, are expected to contribute significant increases in rental income, NOI, and cash flows.

The charts below show (i) the historical and projected trend, and our near and medium-term target of non-income-producing assets as a percentage of our gross investments in real estate and (ii) the allocation of our non-income-producing assets by category:

The projected non-income-producing assets as a percentage of our gross investments in real estate is expected to decrease as we deliver our current value-creation projects under development with significant pre-leasing and completed land sales.

Investment in unconsolidated real estate entity

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 is approximately $350.0 million. The project is 37% pre-leased to Dana-Farber Cancer Institute, Inc. The joint venture had a construction loan with commitments aggregating $213.2 million with $128.0 million outstanding as of June 30, 2014. The remaining cost to complete the development is expected to be funded primarily from the remaining commitments of $85.2 million under the construction loan. The construction loan bears interest at LIBOR+3.75%, with a floor of 5.25%, and has a maturity date of April 1, 2019, inclusive of two separate one-year options to extend the stated maturity date of April 1, 2017.

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 $48.0 million as of June 30, 2014.

We expect to earn unlevered yields on our share of the gross real estate in the joint venture as follows: (i) initial stabilized yield of 8.9%, (ii) initial stabilized yield of 8.3% on a cash basis, and (iii) average cash yields 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 by the joint venture at completion of approximately $108.3 million. In addition to these yields, we will receive construction management and other fees in aggregate of approximately $1.1 million through 2015, and recurring annual property management fees thereafter from this project. Development management fees have been excluded from our estimate of unlevered yields.

Value-creation projects – commencement of development and redevelopment projects in North America

During the six months ended June 30, 2014, we commenced the development of 3013/3033 Science Park Road in the Torrey Pines submarket of San Diego. See further information under “Current value-creation development projects in North America” below.

During the six months ended June 30, 2014, we commenced the redevelopment of two projects in North America, including our redevelopment of 225 Second Avenue in the Route 128 submarket of Greater Boston and 10121 Barnes Canyon Road in the Sorrento Mesa submarket of San Diego. See further information under “Current value-creation redevelopment projects in North America” below.

(1) We have a 27.5% interest in this unconsolidated joint venture accounted for under the equity method of accounting. See further discussion under “Investment in unconsolidated real estate entity” above.

(2) In the three months ended September 30, 2013, we completed the preliminary design and budget for interior improvements for use by ARIAD Pharmaceuticals, Inc. (“ARIAD”). Based upon our lease with ARIAD, we expect an increase in both estimated NOI and estimated cost at completion, with no significant change in our estimated yields. In light of certain changes in ARIAD’S business, ARIAD is reassessing its plans to occupy the entire facility. As a result, plans and drawings for the interior improvements for the project have not been prepared and approved by ARIAD in accordance with the timelines specified in the lease. We expect ARIAD to finalize the design and budget for all or a portion of their interior improvements in the future and will provide an update on our estimated cost at completion and targeted yields. Pursuant to the terms of the lease we expect rent to commence in late March 2015.

Results of operations

Same Properties

As a result of changes within our total property portfolio, the financial data presented in the table in “Comparison of the Three Months Ended June 30, 2014, to the Three Months Ended June 30, 2013” and “Comparison of the Six Months Ended June 30, 2014, to the Six Months Ended June 30, 2013” shows significant changes in revenue and expenses from period to period. In order to supplement an evaluation of our results of operations, we analyze the operating performance for all properties that were operating for the periods presented (“Same Properties”), separate from properties acquired subsequent to the beginning of the earliest period presented, properties currently undergoing development or redevelopment, and corporate entities (legal entities performing general and administrative functions), which are excluded from Same Property results (“Non-Same Properties”). Additionally, rental revenues from lease termination fees, if any, are excluded from the results of the Same Properties.

Rental revenues

Total rental revenues for the three months ended June 30, 2014, increased by $20.5 million, or 17.9%, to $135.0 million, compared to $114.5 million for the three months ended June 30, 2013. The increase was primarily due to rental revenues from our Non-Same Properties, including 11 development and redevelopment projects that were completed and delivered after January 1, 2013, and seven operating properties that were acquired after January 1, 2013. In addition, rental revenues from our Same Properties for the three months ended June 30, 2014, increased by $4.7 million, or 4.3%, to $113.1 million, from $108.4 million for the three months ended June 30, 2013. Occupancy of Same Properties increased by 320 bps to 96.6% for the three months ended June 30, 2014, from 93.4% for the three months ended June 30, 2013.

Tenant recoveries

Tenant recoveries for the three months ended June 30, 2014, increased by $5.1 million, or 14.1%, to $40.9 million, compared to $35.9 million for the three months ended June 30, 2013. This increase is consistent with the increase in our rental operating expenses of $6.1 million. Same Properties tenant recoveries increased by $2.4 million, or 7.1%, primarily as a result of an increase in Same Properties rental operating expenses of $1.9 million, or 4.5%, and higher occupancy for these properties in 2014. Rental operating expenses increased during the three months ended June 30, 2014, compared to the three months ended June 30, 2013, due to higher utilities and repairs and maintenance costs in the three months ended June 30, 2014. Our utility consumption and maintenance costs increased primarily due to our 320 bps increase in occupancy of our Same Properties. Non-Same Properties tenant recoveries increased by $2.7 million as a result of a Non-Same Properties rental operating expense increase of $4.1 million for the development and redevelopment properties delivered since June 30, 2013. As of June 30, 2014, approximately 94% 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.

Other income

Other income for the three months ended June 30, 2014 and 2013, of $0.5 million and $3.6 million, respectively, consisted of the following (in thousands):

	Three Months Ended June 30,
	2014			2013		Change
Management fee income	$	916		$	501	$	415
Interest income	911			990		(79		)
Investment (loss) income	(1,361		)	2,077		(3,438		)
Total other income	$	466		$	3,568	$	(3,102	)

Rental operating expenses

Total rental operating expenses for the three months ended June 30, 2014, increased by $6.1 million, or 13.1%, to $52.4 million, compared to $46.3 million for the three months ended June 30, 2013. Approximately $4.1 million of the increase was due to an increase in rental operating expenses from our Non-Same Properties, primarily related to 11 development and redevelopment projects that were completed and delivered after January 1, 2013, and seven operating properties that were acquired after January 1, 2013.

General and administrative expenses

General and administrative expenses for the three months ended June 30, 2014, increased by $1.4 million, or 11.1%, to $13.8 million, compared to $12.5 million for the three months ended June 30, 2013. General and administrative expenses increased primarily because of higher property acquisition-related expenses due to our recent acquisitions and costs for deals we ultimately did not acquire, higher income taxes related to our foreign operations, and higher professional fees. As a percentage of total assets, our annualized general and administrative expenses were 0.7% and 0.7% for the three months ended June 30, 2014 and 2013, respectively.

62

Interest expense

Interest expense for the three months ended June 30, 2014, increased by $1.5 million, or 9.1%, to $17.4 million, compared to $16.0 million for the three months ended June 30, 2013, detailed as follows (in thousands):

	Three Months Ended June 30,
Component	2014			2013			Change
Secured notes payable	$	7,087		$	9,745		$	(2,658	)
Unsecured senior notes payable	11,241			7,642			3,599
Unsecured senior line of credit	2,698			1,867			831
Unsecured senior bank term loans	3,757			6,076			(2,319		)
Interest rate swaps	1,123			3,834			(2,711		)
Amortization of loan fees and other interest	2,829			2,497			332
Unsecured senior convertible notes	—			7			(7		)
Subtotal	28,735			31,668			(2,933		)
Capitalized interest	(11,302		)	(15,690		)	4,388
Total interest expense	$	17,433		$	15,978		$	1,455

Total interest expense increased by $1.5 million during the three months ended June 30, 2014, compared to the three months ended June 30, 2013, primarily as a result of the $4.4 million reduction in the amount of capitalization of interest related to development and redevelopment construction projects, which results in the expensing of interest costs for the projects upon delivery into service. The lower amount of capitalization of interest was due to the completion of eight projects since June 30, 2013. Gross interest decreased by $2.9 million during the three months ended June 30, 2014, compared to the three months ended June 30, 2013, primarily as a result of reductions in our unsecured senior bank term loan balances of $100.0 million and reductions in our secured notes payable by $95.5 million subsequent to June 30, 2013, and the decrease in expense related to the expiration, subsequent to June 30, 2013, of interest rate swap agreements aggregating $250.0 million with rates approximating 4.9%. In addition, we amended our unsecured senior line of credit and unsecured senior bank term loans in July 2013 and August 2013 to reduce our interest rate, by reducing our credit spread over LIBOR, on outstanding borrowings. The decrease in interest costs was partially offset by an increase in interest expense from the issuance of the $500.0 million unsecured senior notes payable at a fixed rate of 3.90% in May 2013. The decrease in interest costs was also partially offset by an increase in interest expense from a higher overall debt balance, which increased by $375.4 million, to $3.33 billion as of June 30, 2014, compared to $2.96 billion as of June 30, 2013.

Depreciation and amortization

Depreciation and amortization for the three months ended June 30, 2014, increased by $11.0 million, or 23.7%, to $57.3 million, compared to $46.3 million for the three months ended June 30, 2013. Depreciation increased primarily due to depreciation related to our recent acquisitions and the 11 development and redevelopment projects that were completed and delivered after January 1, 2013, and seven operating properties that were acquired in North America after January 1, 2013.

Loss on early extinguishment of debt

During the three months ended June 30, 2013, we recognized a loss on early extinguishment of debt related to the write-off of a portion of unamortized loan fees totaling $560 thousand, upon our $150 million partial repayment of the outstanding principal balance of our 2016 Unsecured Senior Bank Term Loan.

(Loss) income from discontinued operations

Loss from discontinued operations of $147 thousand for the three months ended June 30, 2014, includes the results of operations of four operating properties that were classified as “held for sale” as of June 30, 2014.

Income from discontinued operations of $249 thousand for the three months ended June 30, 2013, includes the results of operations of four operating properties that were classified as “held for sale” as of June 30, 2014, and the results of operations of one property sold subsequent to April 1, 2013.

Rental revenues

Total rental revenues for the six months ended June 30, 2014, increased by $39.5 million, or 17.5%, to $265.6 million, compared to $226.0 million for the six months ended June 30, 2013. The increase was primarily due to rental revenues from our Non-Same Properties, including 11 development and redevelopment projects that were completed and delivered after January 1, 2013, and seven operating properties that were acquired after January 1, 2013. In addition, rental revenues from our Same Properties for the six months ended June 30, 2014, increased by $7.8 million, or 3.7%, to $221.1 million from $213.2 million for the six months ended June 30, 2013. Occupancy of Same Properties increased by 340 bps to 96.5% for the six months ended June 30, 2014, from 93.1% for the six months ended June 30, 2013.

Tenant recoveries

Tenant recoveries for the six months ended June 30, 2014, increased by $11.2 million, or 15.7%, to $82.6 million, compared to $71.4 million for the six months ended June 30, 2013. This increase is consistent with the increase in our rental operating expenses of $13.4 million. Same Properties tenant recoveries increased by $5.2 million, or 7.7%, primarily as a result of an increase in Same Properties rental operating expenses of $4.4 million, or 5.2%, and higher recoveries from increases in occupancy for these properties in 2014. Rental operating expenses increased during the six months ended June 30, 2014, compared to the six months ended June 30, 2013, due to higher utilities, contract services, and repairs and maintenance costs in the six months ended June 30, 2014. Our East Coast properties incurred additional heating, snow removal, and other maintenance costs due to a severe winter in 2014. Operating expenses also increased in our operating portfolio due to our increase in occupancy since 2013. Our utility consumption and maintenance costs increased primarily due to our 340 bps increase in occupancy of our Same Properties. Non-Same Properties tenant recoveries increased by $5.9 million as a result of a Non-Same Properties rental operating expense increase of $9.0 million.

Other income

Other income for the six months ended June 30, 2014 and 2013, of $4.4 million and $6.6 million, respectively, consisted of the following (in thousands):

	Six Months Ended June 30,
	2014		2013		Change
Management fee income	$	1,642	$	2,106	$	(464	)
Interest income	1,773		2,317		(544		)
Investment income	985		2,137		(1,152		)
Total other income	$	4,400	$	6,560	$	(2,160	)

Rental operating expenses

Total rental operating expenses for the six months ended June 30, 2014, increased by $13.4 million, or 14.6%, to $104.9 million, compared to $91.5 million for the six months ended June 30, 2013. Approximately $9.0 million of the increase was due to an increase in rental operating expenses from our Non-Same Properties, primarily related to 11 development and redevelopment projects that were completed and delivered after January 1, 2013, and seven operating properties that were acquired after January 1, 2013.

General and administrative expenses

General and administrative expenses for the six months ended June 30, 2014, increased by $3.0 million, or 12.3%, to $27.1 million, compared to $24.1 million for the six months ended June 30, 2013. General and administrative expenses increased primarily because of higher property acquisition-related expenses due to our recent acquisitions and costs for deals we ultimately did not acquire, higher income taxes related to our foreign operations, and professional fees. As a percentage of total assets, our annualized general and administrative expenses were 0.7% and 0.7% for the six months ended June 30, 2014, and 2013, respectively.

65

Interest expense

Interest expense for the six months ended June 30, 2014, increased by $2.6 million, or 7.5%, to $36.6 million, compared to $34.0 million for the six months ended June 30, 2013, detailed as follows (in thousands):

	Six Months Ended June 30,
Component	2014			2013			Change
Secured notes payable	$	15,058		$	19,549		$	(4,491	)
Unsecured senior notes payable	22,481			13,977			8,504
Unsecured senior line of credit	4,737			4,761			(24		)
Unsecured senior bank term loans	7,499			12,301			(4,802		)
Interest rate swaps	4,613			8,142			(3,529		)
Amortization of loan fees and other interest	5,483			4,966			517
Unsecured senior convertible notes	—			13			(13		)
Subtotal	59,871			63,709			(3,838		)
Capitalized interest	(23,315		)	(29,711		)	6,396
Total interest expense	$	36,556		$	33,998		$	2,558

Total interest expense increased by $2.6 million during the six months ended June 30, 2014, compared to the six months ended June 30, 2013, primarily as a result of the $6.4 million reduction in the amount of capitalization of interest related to development and redevelopment construction projects which results in the expensing of interest costs for the projects upon delivery into service. The lower amount of capitalization of interest was due to the completion of eight projects since June 30, 2013. Gross interest decreased by $3.8 million during the six months ended June 30, 2014, compared to the six months ended June 30, 2013, primarily as a result of reductions in our unsecured senior bank term loan balances by $100.0 million and reductions in our secured notes payable by $95.5 million subsequent to June 30, 2013, and the decrease in expense related to the expiration, subsequent to March 31, 2013, of interest rate swap agreements aggregating $300.0 million with rates approximating 4.9%. In addition, we amended our unsecured senior line of credit and unsecured senior bank term loans in July 2013 and August 2013 to reduce our interest rate, by reducing our credit spread over LIBOR, on outstanding borrowings. The decrease in interest costs was partially offset by an increase in interest expense from a higher overall debt balance, which increased by $375.4 million, to $3.33 billion as of June 30, 2014, compared to $2.96 billion as of June 30, 2013.

Depreciation and amortization

Depreciation and amortization for the six months ended June 30, 2014, increased by $15.6 million, or 16.9%, to $107.7 million, compared to $92.2 million for the six months ended June 30, 2013. Depreciation increased due to building improvements, including 11 development and redevelopment projects that were completed and delivered after January 1, 2013, and seven operating properties that were acquired in North America after January 1, 2013.

Loss on early extinguishment of debt

During the six months ended June 30, 2013, we recognized a loss on early extinguishment of debt related to the write-off of a portion of unamortized loan fees totaling $560 thousand, upon our $150 million partial repayment of the outstanding principal balance of our 2016 Unsecured Senior Bank Term Loan.

(Loss) income from discontinued operations

Loss from discontinued operations of $309 thousand for the six months ended June 30, 2014, includes the results of operations of four operating properties that were classified as “held for sale” as of June 30, 2014.

Income from discontinued operations of $1.1 million for the six months ended June 30, 2013, includes the results of operations of four operating properties that were classified as “held for sale” as of June 30, 2014, and the results of operations of seven properties sold subsequent to January 1, 2013.

Projected results

Based on our current view of existing market conditions and certain current assumptions, we have updated guidance for earnings per share attributable to Alexandria’s common stockholders – diluted and FFO per share attributable to Alexandria’s common stockholders – diluted, each for the year ended December 31, 2014, 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 earnings per share, the most directly comparable GAAP measure, and other key assumptions and key credit metrics included in our guidance for the year ended December 31, 2014.

EPS and FFO Per Share Attributable to Alexandria’s Common Stockholders – Diluted	2014 Guidance
Earnings per share	$1.63 – $1.69
Add back: depreciation and amortization	3.13
Other (1)	(0.03)
FFO per share	4.73 – 4.79
Add back: loss on early extinguishment of debt (2)	0.01
FFO per share, as adjusted	$4.74 – $4.80

(1) Includes an adjustment to eliminate the $0.01 per share gain realized on the sale of a land parcel in the second quarter of 2014.

(2) Represents loss on early extinguishment of debt related to the write-off of unamortized loan fees of $0.01 per share as a result of the $125 million partial repayment of our 2016 Unsecured Senior Bank Term Loan in July 2014.

	2014 Guidance
Key Assumptions (Dollars in thousands)	Low		High
Occupancy percentage for operating properties in North America at December 31, 2014:	96.7%		97.2%
Same property performance:
NOI increase	3%		5%
NOI increase (cash basis)	4%		6%
Lease renewals and re-leasing of space:
Rental rate increases	11%		14%
Rental rate increases (cash basis)	4%		6%
Straight-line rents	$	42,000	$	47,000
General and administrative expenses	$	48,000	$	52,000
Capitalization of interest	$	37,000	$	47,000
Interest expense	$	76,000	$	92,000

Key Credit Metrics	As of December 31, 2014
Net debt to Adjusted EBITDA – fourth quarter of 2014 annualized	6.8x
Net debt to Adjusted EBITDA – trailing 12 months	7.2x
Fixed charge coverage ratio – fourth quarter of 2014 annualized	3.3x
Fixed charge coverage ratio – trailing 12 months	3.3x
Unhedged variable-rate debt as a percentage of total debt	≤11%
Non-income-producing assets as a percentage of gross investments in real estate	≤15%

On a short-term basis, our unhedged variable-rate debt as a percentage of total debt may range up to 25%. Our strategy is to have unhedged variable-rate debt available for repayment as we issue unsecured senior notes payable, extend our maturity profile, transition variable-rate debt to fixed rate debt, and enhance our long-term capital structure.

67

Net Debt to Adjusted EBITDA	Fixed Charge Coverage Ratio

Our guidance assumes 7.2x and 6.8x net debt to adjusted EBITDA for the trailing 12 months ended and three months annualized December 31, 2014, respectively.

Key capital planning considerations

We expect to generate significant internal funding capacity from the delivery of pre-leased development and redevelopment projects that will drive a substantial decline in non-income producing assets, contribute additional operating cash flow and produce significant growth in EBITDA. We expect our growth in EBITDA will allow us to fund construction through additional borrowings while maintaining our target leverage ratio of 6.5x debt to EBITDA.

(1) Represents non-income-producing assets as a percentage of gross investments in real estate. See pre-leasing of current projects on pages 54 and 55.

(2) Represents estimated net cash provided by operating activities after dividends.

(3) Represents amount of construction that can be funded by debt through growth in adjusted EBITDA on a leverage neutral basis (6.5x net debt to adjusted EBITDA by 4Q15). Excludes EBITDA from projected acquisitions.

Liquidity and capital resources

Overview

We expect to meet certain long-term liquidity requirements, such as requirements for property acquisitions, development, redevelopment, predevelopment, other construction projects, capital improvements, tenant improvements, 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:

• Reduce our amount of 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 ventures, preferred stock, and common stock;

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

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

• 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 secured construction loans;

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

• Fund preferred stock and common stock dividends from net cash provided by operating activities;

• Retain positive cash flows from operating activities after payment of dividends for reinvestment in acquisitions and/or development and redevelopment projects;

• Continue to reduce our non-income-producing assets as a percentage of our gross investment in real estate through our continued delivery of development and redevelopment projects, and selective land sales; 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 $1.7 billion as of June 30, 2014, under our 2016 unsecured senior bank term loan (“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 at June 30, 2014				As of June 30, 2014
Facility					Maturity Date (1)	Applicable Rate	Facility Fee
2016 Unsecured Senior Bank Term Loan	$	500	million	(2)	July 2016	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	$	571	million	(2)	January 2019	L+1.10%	0.20	%

(1) Includes any extension options that we control.

(2) Net proceeds of $694 million from our unsecured senior notes payable offering completed on July 18, 2014, were used to reduce variable-rate debt, including 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.

69

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 will 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. 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 June 30, 2014, were as follows:

Covenant Ratios (1)	Requirement	Actual (2)
Leverage Ratio	Less than or equal to 60.0%	34.2%
Secured Debt Ratio	Less than or equal to 45.0%	6.3%
Fixed Charge Coverage Ratio	Greater than or equal to 1.50x	2.94x
Unsecured Leverage Ratio	Less than or equal to 60.0%	36.8%
Unsecured Interest Coverage Ratio	Greater than or equal to 1.50x	9.08x

(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.

Unsecured senior notes payable

The requirements of, and our actual performance with respect to, the key financial covenants under our 3.90% Unsecured Senior Notes and 4.60% Unsecured Senior Notes as of June 30, 2014, were as follows:

Covenant Ratios (1)	Requirement	Actual
Total Debt to Total Assets	Less than or equal to 60%	38%
Secured Debt to Total Assets	Less than or equal to 40%	7%
Consolidated EBITDA to Interest Expense	Greater than or equal to 1.5x	6.9x
Unencumbered Total Asset Value to Unsecured Debt	Greater than or equal to 150%	266%

(1) For definitions of the ratios, refer to the indenture and related supplemental indentures, which were filed as exhibits to our Current Reports on Form 8-K with the SEC on February 29, 2012, and June 7, 2013, respectively.

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.

Sources and uses of capital

We expect that our principal liquidity needs for the year ended December 31, 2014, 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.

(1) Includes two non-recourse secured notes payable aggregating $48.3 million assumed in connection with the acquisition of two operating assets in the three months ended March 31, 2014, as well as borrowings under secured construction loans.

The key assumptions behind the sources and uses of capital in the table above are a favorable capital market environment and performance of our core operations in areas such as delivery of current and future development and redevelopment projects, leasing activity, and renewals.  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, 2013.  We expect to update our forecast of sources and uses of capital on a quarterly basis.

Sources of capital

2.75% and 4.50% unsecured senior 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% (“2.75% Unsecured Senior Notes”) and 4.50% (“4.50% Unsecured Senior Notes”), respectively.  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 effectively 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, including 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.

Real estate sales/strategic joint venture capital

We continue the disciplined execution of our asset recycling program to monetize non-strategic non-income-producing assets as a source of capital through asset sales or from joint venture proceeds. For 2014, we expect to monetize $145.0 million to $245.0 million through the sale of real estate or from joint venture proceeds related to non-income-producing assets. 

As of June 30, 2014, we also had four properties classified as “held for sale” with an aggregate book value of $7.7 million.

Secured construction loans

See Note 5 – 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.

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.  In July 2014, we completed a $700 million unsecured senior notes payable offering. Net proceeds from this offering were used to reduce approximately $569 million of borrowings outstanding on our unsecured senior line of credit and increased our borrowing capacity under the unsecured line to approximately $1.5 billion.

72

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 banker’s 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%. The Applicable Margin for LIBOR borrowings under the unsecured senior line of credit as of June 30, 2014, was 1.10%, which is based on our existing credit rating as set by certain rating agencies. Our unsecured senior line of credit is subject to an annual facility fee of 0.20% based on the aggregate commitments outstanding.

Cash and cash equivalents

As of June 30, 2014, and December 31, 2013, we had $61.7 million and $57.7 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 material capital expenditures, for at least the next 12 months, and thereafter for the foreseeable future.

Restricted cash

Restricted cash consisted of the following as of June 30, 2014, and December 31, 2013 (in thousands):

	June 30, 2014		December 31, 2013
Funds held in trust under the terms of certain secured notes payable	$	16,804	$	14,572

The funds held in escrow related to construction projects will be used to pay for certain construction costs.

Other sources

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

We hold interests, together with certain third parties, in companies that we consolidate in our financial statements.  These third parties may contribute equity into these entities primarily related to their share of funds for construction-related and financing-related activities. In January 2014, our joint venture partner funded $20.9 million related to the repayment of our $208.7 million secured note payable collateralized by Alexandria Technology Square^®.

We also hold an interest, together with certain third parties, in a joint venture that is not consolidated in our financial statements. The following table presents information related to debt held by our unconsolidated joint venture (dollars in thousands):

Loan Collateral	Total Commitments		Total Outstanding		Third Party Share		ARE Share			Maturity Date			Interest Rate
360 Longwood Avenue	$	213,200	$	128,003	$	92,802	$	35,201	(1)		4/1/2017	(2)		5.25	%	(3)

(1) We have a 27.5% equity interest in this unconsolidated joint venture.

(2) We have two, one-year options to extend the stated maturity date to April 1, 2019, subject to certain conditions.

(3) Secured construction loan bears interest at LIBOR+3.75%, with a floor of 5.25%.

Uses of capital

2016 Unsecured Senior Bank Term Loan partial repayment

In July 2014, we repaid $125 million of the outstanding principal balance of our 2016 Unsecured Senior Bank Term Loan by utilizing a portion of the proceeds generated by the issuance of our 2.75% Unsecured Senior Notes and 4.50% Unsecured Senior Notes. As a result of the $125 million partial repayment, we recognized a loss on early extinguishment of debt related to the write-off of a portion of unamortized loan fees in July 2014, totaling $0.5 million.

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 1,000,500 RSF of laboratory/office space. In addition, we have a 27.5% interest in an unconsolidated joint venture that is currently developing a building aggregating 413,536 RSF in the Longwood Medical Area of the Greater Boston market. 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.

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 six months ended June 30, 2014 and 2013, of $23.3 million and $29.7 million, respectively, is classified in investments in real estate, net.  We also capitalize indirect project costs, including construction administration, compensation costs, legal fees, and office costs that clearly relate to projects under development or construction, during the period an asset is undergoing activities to prepare it for its intended use.  We capitalized compensation and other indirect project costs related to development, redevelopment, predevelopment, and construction projects, aggregating $8.9 million and $7.4 million for the six months ended June 30, 2014 and 2013, 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 properties, net.  Also, if aboveground construction is not initiated at completion of predevelopment activities, the land parcel will be 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, predevelopment, and construction activities without a corresponding decrease in indirect project costs, including interest and payroll, total expenses would have increased by approximately $3.1 million for the six months ended June 30, 2014.

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.  The initial direct costs capitalized and deferred also included compensation costs for employees related to time spent directly performing leasing activities previously described and related to leasing responsibilities that would not have been performed had the leasing transaction not occurred. Total initial direct leasing costs capitalized during the six months ended June 30, 2014 and 2013, were $19.2 million and $21.1 million, respectively, of which $6.5 million and $5.4 million, respectively, represented capitalized and deferred payroll costs directly related and essential to our leasing activities during such periods.

Acquisitions

Refer to the “External Growth – Acquisitions” section.

Dividends

We are required to distribute at least 90% of our REIT taxable income on an annual basis in order to continue to qualify as a REIT for federal income tax purposes.  Accordingly, we intend to make, but are not contractually bound to make, regular quarterly distributions to preferred and common stockholders from cash flow from operating activities.  All such distributions are at the discretion of our Board of Directors.  We may be required to use borrowings under our unsecured senior line of credit, if necessary, to meet REIT distribution requirements and maintain our REIT status.  We consider market factors and our performance in addition to REIT requirements in determining distribution levels.

Cash flows

We report and analyze our cash flows based on operating activities, investing activities, and financing activities.  The following table summarizes changes in the Company’s cash flows for the six months ended June 30, 2014 and 2013 (in thousands):

	Six Months Ended June 30,
	2014			2013			Change
Net cash provided by operating activities	$	144,491		$	144,141		$	350
Net cash used in investing activities	$	(273,177	)	$	(216,472	)	$	(56,705	)
Net cash provided by financing activities	$	131,854		$	235,525		$	(103,671	)

Operating activities

Cash flows provided by operating activities consisted of the following amounts (in thousands):

	Six Months Ended June 30,
	2014		2013		Change
Net cash provided by operating activities	$	144,491	$	144,141	$	350
Add back: Changes in operating assets and liabilities	24,018		7,545		16,473
Net cash provided by operating activities before changes in operating assets and liabilities	$	168,509	$	151,686	$	16,823

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 tenants, the delivery of development projects, and the timing and delivery of redevelopment projects. Net cash provided by operating activities for the six months ended June 30, 2014, increased to $144.5 million, compared to $144.1 million for the six months ended June 30, 2013.  Net cash provided by operating activities before changes in assets and liabilities for the six months ended June 30, 2014, increased by $16.8 million, or 11.1%, to $168.5 million, compared to $151.7 million for the six months ended June 30, 2013.  This increase was primarily attributable to an increase in our Same Properties NOI (cash basis) of $9.3 million, or 5.0%, to $193.3 million for the six months ended June 30, 2014, compared to $184.0 million for the six months ended June 30, 2013. In addition, the increase in operating cash flows was attributable to our delivery of 11 development and redevelopment projects since January 1, 2013, and seven operating properties that were acquired after January 1, 2013. These increases were partially offset by the sale of seven non-strategic properties over the same period.

Investing activities

Net cash used in investing activities for the six months ended June 30, 2014, was $273.2 million, compared to $216.5 million for the six months ended June 30, 2013.  This change consisted of the following (in thousands):

	Six Months Ended June 30,
	2014			2013			Change
Proceeds from sales of properties	$	17,868		$	101,815		$	(83,947	)
Additions to properties	(210,792		)	(298,927		)	88,135
Purchase of properties	(97,785		)	—			(97,785		)
Proceeds from repayment of note receivable	29,851			—			29,851
Other	(12,319		)	(19,360		)	7,041
Net cash used in investing activities	$	(273,177	)	$	(216,472	)	$	(56,705	)

The change in net cash used in investing activities for the six months ended June 30, 2014, is primarily due to a higher use of cash for property acquisitions and a lower source of cash from property dispositions, offset by lower capital expenditures incurred on our development and redevelopment projects, as construction completed on many of the 11 development and redevelopment projects that were completed and delivered after January 1, 2013, and offset by the collection of a note receivable during the six months ended June 30, 2014, as compared to the six months ended June 30, 2013.

For information on our key development and redevelopment projects for the six months ended June 30, 2014, see “Investment in Real Estate, Net – Development, Redevelopment, and Future Value-Creation Projects” located earlier within Item 2 of this report and preceding “Investment in Unconsolidated Real Estate Entity.”

Financing activities

Net cash provided by financing activities for the six months ended June 30, 2014, decreased by $103.7 million, to $131.9 million, compared to cash provided by financing activities of $235.5 million for the six months ended June 30, 2013.  This decrease consisted of the following amounts (in thousands):

	Six Months Ended June 30,
	2014			2013			Change
Borrowings from secured notes payable	$	77,762		$	26,114		$	51,648

$700 million offering of unsecured senior notes payable

In July 2014, we completed an offering of $700 million aggregate principal amount unsecured senior notes payable at a weighed average interest rate of 3.50% and a weighted average tenor of 9.6 years. The offering included $400 million aggregate principal amount of our 2.75% Unsecured Senior Notes and $300 million aggregate principal amount of our 4.50% Unsecured Senior Notes. The net proceeds of $694 million were used to repay $125 million of our 2016 Unsecured Senior Bank Term Loan and to reduce $569 million 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 $0.5 million, or $0.01 per share.

Secured construction loans

See the “Secured Construction Loans” section under “Sources and Uses of Capital” in Item 2 of this report for details.

Dividends

During the six months ended June 30, 2014 and 2013, we paid the following dividends (in thousands):

	Six Months Ended June 30,
	2014		2013		Change
Common stock dividends	$	98,867	$	73,932	$	24,935
Series D Preferred Stock dividends	8,750		8,750		—
Series E Preferred Stock dividends	4,193		4,192		1
	$	111,810	$	86,874	$	24,936

76

The increase in dividends paid on our common stock was primarily due to an increase in the related dividends to $1.38 per common share for the six months ended June 30, 2014, from $1.16 per common share for the six months ended June 30, 2013.  The increase was also due to an increase in the number of shares of common stock outstanding to 71.3 million shares as of June 30, 2014, compared to 71.0 million shares as of June 30, 2013.

Inflation

As of June 30, 2014, approximately 94% 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 96% 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 another index.  Accordingly, we do not believe that our cash flow or earnings from real estate operations are subject to any significant risk 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.

Contractual obligations and commitments

Contractual obligations as of June 30, 2014, consisted of the following (in thousands):

			Payments by Period
	Total		2014		2015 – 2016		2017 – 2018		Thereafter
Secured and unsecured debt (1) (2)	$	3,336,112	$	11,624	$	814,433	$	148,447	$	2,361,608
Estimated interest payments on fixed rate and hedged variable-rate debt (3)	500,301		47,697		153,443		113,358		185,803
Estimated interest payments on variable-rate debt (4)	38,772		3,640		20,536		14,596		—
Ground lease obligations	682,638		5,936		20,498		21,343		634,861
Other obligations	9,118		837		2,923		3,209		2,149
Total	$	4,566,941	$	69,734	$	1,011,833	$	300,953	$	3,184,421

(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 were 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 were based on the interest rates in effect as of June 30, 2014.

Estimated interest payments

As of June 30, 2014, 72% of our debt was fixed rate debt or variable-rate debt subject to interest rate swap agreements.  See additional information regarding our interest rate swap agreements under “Liquidity and Capital Resources – Contractual Obligations and Commitments – Interest Rate Swap Agreements.”  The remaining 28% of our debt is 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 June 30, 2014.  See additional information regarding our debt under Note 5 – 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

See Note 6 – Interest Rate Swap Agreements to our consolidated financial statements (unaudited) appearing elsewhere in this quarterly report on Form 10-Q for further information.

Ground lease obligations

Ground lease obligations as of June 30, 2014, included leases for 29 of our 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 $10.2 million at June 30, 2014, our ground lease obligations have remaining lease terms ranging from 40 to 100 years, including extension options.

77

Commitments

In addition to the above, as of June 30, 2014, remaining aggregate costs under contract for the construction of properties undergoing development, redevelopment, and generic science and technology infrastructure improvements under the terms of leases approximated $323.4 million.  We expect payments for these obligations to occur over one to three years, subject to capital planning adjustments from time to time.  We are also committed to funding approximately $50.4 million for certain investments over the next several years. In addition, we have letters of credit and performance obligations of $13.8 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. At June 30, 2014, we have land and land improvements with an aggregate book value of $20.9 million for which we have construction commitment obligations aggregating approximately 300,000 RSF that need to be fulfilled by 2016. 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 also 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 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.

Off-balance sheet arrangements

Our off-balance sheet arrangements consist of our investment in a real estate entity that is a variable interest entity for which we are not the primary beneficiary.  We account for the investment in the real estate entity under the equity method of accounting.  See Notes 3 and 5 to our consolidated financial statements (unaudited) appearing elsewhere in this quarterly report on Form 10-Q, as well as Notes 2 and 3 to our consolidated financial statements appearing in our annual report on Form 10-K for the year ended December 31, 2013.

Critical accounting policies

Refer to our annual report on Form 10-K for the year ended December 31, 2013, for a discussion of our critical accounting policies, which include rental properties, net, land held for future development, construction in progress, 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 client tenant credit quality.  There were no significant changes to these policies during the six months ended June 30, 2014.

Non-GAAP measures

Funds from operations and funds from operations, 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 National Association of Real Estate Investment Trusts (“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 land parcels, impairments of investments, deal costs, 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.  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.

Adjusted funds from operations

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 and straight-line rent 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.

We believe that AFFO is a useful supplemental performance measure because it further adjusts 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 most directly comparable GAAP financial measure to AFFO.  We believe that AFFO is a widely recognized measure of the operations of equity REITs, and our presentation of AFFO will enable investors to assess our performance in comparison to that of 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.

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 (“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 and land parcels, deal costs, and impairments. 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 land parcels, deal costs, and impairments.  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							Six Months Ended					Year Ended

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, 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 June 30, 2014, and on our annual report on Form 10-K, as of December 31, 2013.

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.  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 June 30, 2014, and December 31, 2013 (dollars in thousands):

	As of June 30, 2014			As of December 31, 2013

NOI

NOI is a non-GAAP financial measure equal to income from continuing operations, the most directly comparable GAAP financial measure, excluding loss (gain) on early extinguishment of debt, impairment of land parcel, depreciation and amortization, interest expense, and general and administrative expense.  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

83

cash basis is helpful to investors as an additional measure of operating performance because it eliminates straight-line rent adjustments to rental revenue.

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 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.  Real estate impairments have been excluded in deriving NOI because we do not consider impairment losses to be property-level operating expenses.  Real estate impairment losses 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 real estate impairments 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 condensed 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 Property 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

Unencumbered NOI as a percentage of total NOI is a non-GAAP financial measure that we believe is useful to investors as a performance measure of our 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 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 that are not subject to any mortgage, deed of trust, lien, or other security interest as of the period for which income is presented.  Unencumbered NOI for periods prior to the three months ended June 30, 2014, has been reclassified to conform to current period presentation related to discontinued operations.  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 and six months ended June 30, 2014 and 2013 (dollars in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2013		2014		2013
Unencumbered NOI	$	103,951	$	74,966	$	207,047	$	146,109
Encumbered NOI	20,098		32,687		40,681		66,441
Total NOI from continuing operations	$	124,049	$	107,653	$	247,728	$	212,550

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% increase/decrease 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 June 30, 2014 (in thousands):

Annualized impact to future earnings due to variable-rate debt:
Rate increase of 1%	$	(5,749	)
Rate decrease of 1%	$	876
Effect on fair value of total consolidated debt and interest rate swap agreements:
Rate increase of 1%	$	(122,358	)
Rate decrease of 1%	$	106,398

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 June 30, 2014.  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 or 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 June 30, 2014 (in thousands):

Equity price risk:
Increase in fair value of 10%	$	17,480
Decrease in fair value of 10%	$	(17,480	)

85

Foreign currency exchange rate risk

We have exposure to foreign currency exchange rate risk related to our subsidiaries operating in Canada and Asia.  The functional currencies of our foreign subsidiaries are the respective local currencies.  Gains or losses resulting from the translation of our foreign subsidiaries’ balance sheets and statements of income are classified in accumulated other comprehensive income as a separate component of total equity.  Gains or losses will be reflected in our 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% increase or decrease in foreign currency rates relative to the U.S. dollar would have on our earnings, based on our current operating assets outside the U.S. as of June 30, 2014 (in thousands):

Foreign currency exchange rate risk:
Increase in foreign currency exchange rate of 10%	$	(157	)
Decrease in foreign currency exchange rate of 10%	$	157

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 six months ended June 30, 2014, 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 June 30, 2014, we had performed an evaluation, under the supervision of our Chief Executive Officer (“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 June 30, 2014.

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 June 30, 2014, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

86

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, 2013.  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.

Acquisitions

In January 2014, we acquired 3545 Cray Court, a 116,556 RSF laboratory/office property located in the Torrey Pines submarket of San Diego, for $64.0 million. The property was 100% occupied on the date of acquisition. In connection with the acquisition, we assumed a $40.7 million non-recourse secured note payable with a contractual interest rate of 4.66% and a maturity in January 2023.

In March 2014, we acquired 225 Second Avenue, a vacant 112,500 RSF office property located in the Route 128 submarket of Greater Boston, for $16.3 million. In May 2014, we leased 100% of the project to accommodate expansion requirements of an existing tenant. The property is undergoing conversion into laboratory/office space through redevelopment.

In March 2014, we acquired 4025/4031/4045 Sorrento Valley Boulevard, three adjacent buildings aggregating 42,566 RSF located in the Sorrento Valley submarket of San Diego, for a total purchase price of $12.4 million. These properties were 100% occupied on the date of acquisition. In connection with the acquisition, we assumed a $7.6 million non-recourse secured note payable with a contractual interest rate of 5.74% and a maturity in April 2016.

In April 2014, we acquired 500 Townsend Street, a land parcel supporting approximately 300,000 gross square feet, in the South of Market (“SoMa”) submarket of the San Francisco Bay Area for a purchase price of $50.0 million. We are in the process of perfecting entitlements, marketing for lease, and subject to market conditions, we plan to commence construction as soon as possible in 2015.

Current development and redevelopment projects

As of June 30, 2014, we hadsixground-up development projects in process in North America aggregating1.4 millionRSF, including an unconsolidated joint venture development project. We also hadthreeprojects undergoing redevelopment in North America aggregating197,289 RSF.

Investment in unconsolidated real estate entity

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 is approximately $350.0 million. The project is 37% pre-leased to Dana-Farber Cancer Institute, Inc. The joint venture had a construction loan with commitments aggregating $213.2 million with $128.0 million outstanding as of June 30, 2014. The remaining cost to complete the development is expected to be funded primarily from the remaining commitments of $85.2 million under the construction loan. The construction loan bears interest at LIBOR+3.75%, with a floor of 5.25%, and has a maturity date of April 1, 2019, inclusive of two separate one-year options to extend the stated maturity date of April 1, 2017.

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 $48.0 million as of June 30, 2014.

We do not qualify as the primary beneficiary of the unconsolidated joint venture since we do not have the power to direct the activities of the entity that most significantly impact its economic performance. The decisions that most significantly impact the entity’s economic performance require both our consent and that of our partners, including all major operating, investing, and financing decisions, as well as decisions involving major expenditures. Consequently, we do not consolidate this joint venture, and we account for our investment under the equity method of accounting.

Land undergoing predevelopment activities (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 undergoing predevelopment activities without first securing pre-leasing for such space, except when there is significant market demand.  If aboveground construction is not initiated at completion of predevelopment activities, the land parcel will be classified as land held for development.  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 and multi-tenancy. As of June 30, 2014, we held land undergoing predevelopment activities in North America aggregating 2.5 million RSF. The largest project included in land undergoing predevelopment activities consists of substantially all of our 1.1 million square feet at the Alexandria Center™ at Kendall Square located in East Cambridge, Massachusetts.

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

Ÿ 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

Ÿ 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. For example, site and infrastructure costs for the 1.1 million RSF primarily related to 50, 60, and 100 Binney Street of the Alexandria Center™ at Kendall Square are classified as predevelopment prior to commencement of vertical construction.

Land held for development

Land held for development represents real estate 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 June 30, 2014, we had land held for development in North America supporting an aggregate of 3.2 million RSF of ground-up development.

Dispositions

During the six months ended June 30, 2014, we sold a land parcel for consideration of $19.0 million to a buyer expected to reposition the property for multi-family residential use. We recognized a gain of $0.8 million on the sale. This gain is classified in gain on sale of land parcel in the accompanying consolidated statements of income.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of presentation

Basis of presentation

We have prepared the accompanying interim consolidated financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) and in conformity with the rules and regulations of the Securities and Exchange Commission (“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, 2014.  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, 2013.

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.

We hold interests, together with certain third parties, in companies that we consolidate in our financial statements. We consolidate the companies because we exercise significant control over major decisions by these entities, such as investment activity and changes in financing.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation for discontinued operations.

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

Investments in real estate, net, and discontinued operations

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, 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.  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 lives 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 activities 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.  When all of these criteria have been met, the property is classified as “held for sale,” and if (i) the operations and cash flows of the property have been or will be eliminated from the ongoing operations, and (ii) we will not have any significant continuing involvement in the operations of the property after the sale, then its operations, 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.  Depreciation of assets ceases upon designation of a property as “held for sale.”

Impairment of long-lived assets

Long-lived assets to be held and used, including our rental properties, land held for development, construction in progress, 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, land held for development, and construction in progress, are assessed by project and include significant fluctuations in estimated net operating income (“NOI”), 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 life 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 and limited partnerships 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 and limited partnerships are accounted for under the equity method when our interest in the entity is not deemed 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 interest of each individual entity to less than 10%.  As of June 30, 2014, and December 31, 2013, our ownership percentage in the voting interest of each individual entity was less than 10%.

We monitor each of our investments throughout the year for new developments, including operating results, results of clinical trials, capital-raising events, and merger and acquisition activities. Individual investments 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 would 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.

Income taxes

We are organized and qualify as a REIT pursuant to the Internal Revenue Code of 1986, as amended (the “Code”).  Under the Code, a REIT that distributes 100% of its REIT taxable income as a dividend to its shareholders each year and that meets certain other conditions is not subject to federal income taxes, but could be subject to certain state and local taxes.  We have distributed 100% or more of our taxable income.  Therefore, no provision for federal income taxes is required.  We file tax returns, including returns for our subsidiaries, with federal, state, and local jurisdictions, including jurisdictions located in the United States (“U.S.”), Canada, India, China, and other international locations.  Our tax returns are subject to examination in various jurisdictions for the calendar years 2009 through 2013.

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 an asset in 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.

Tenant recoveries related to reimbursement of real estate taxes, insurance, utilities, repairs and maintenance, 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 rent and deferred rent receivables arising from the straight-lining of rent.  As of June 30, 2014, and December 31, 2013, we had no allowance for estimated losses.

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 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 life science industry, as well as in finance. This research team is responsible for assessing and monitoring the credit quality of our client tenants and any material changes in credit quality.

Interest income

Interest income was $911 thousand and $990 thousand during the three months ended June 30, 2014 and 2013, respectively. Interest income was $1.8 million and $2.3 million during the six months ended June 30, 2014 and 2013, respectively.  Interest income is included in other income in the accompanying consolidated statements of income.

Impact of recently issued accounting standards

In April 2014, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) on the reporting of discontinued operations, which raises the threshold for disposals to qualify as discontinued operations. Under this ASU, a discontinued operation is (i) a component of an entity or group of components that has been disposed of by sale, that has been disposed of other than by sale, or that is classified as “held for sale” and represents a strategic shift that has had or will have a major effect on an entity’s operations and financial results or (ii) an acquired business or nonprofit activity that is classified as “held for sale” on the date of the acquisition. A strategic shift that has or will have a major effect on an entity’s operations and financial results could include the disposal of (i) a major line of business, (ii) a major geographic area, (iii) a major equity method investment, or (iv) other major parts of an entity. Under current GAAP, an entity is prohibited from reporting a discontinued operation if it has certain continuing cash flows or involvement with the component after the disposal. This ASU eliminates these criteria and is effective for public companies during the interim and annual periods, beginning after December 15, 2014. We are required to adopt this ASU no later than January 1, 2015 and may early adopt this ASU during interim periods, as applicable. We expect the adoption of this ASU to result in fewer real estate sales qualifying for classification as discontinued operations in our consolidated financial statements.

In May 2014, the FASB issued an ASU that replaces substantially all industry-specific revenue recognition requirements and converges areas under this topic with International Financial Reporting Standards. The ASU implements a five-step process for customer contract revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards. The ASU also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows from contracts with customers. Other major provisions in this ASU include capitalizing and amortizing certain contract costs, ensuring the time value of money is considered in the applicable transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. The ASU is effective for reporting periods beginning after December 15, 2016, and early adoption is prohibited. The ASU does not apply to lease contracts accounted for under current GAAP. We are currently evaluating the impact of the adoption of this ASU will have on our financial position and results of operations.

[1] Represents the weighted average interest rate as of the end of the period plus the impact of debt premiums/discounts and our interest rate swap agreements. The weighted average interest rate excludes bank fees and amortization of loan fees.

[2] Includes any extension options that we control.

[3] These amounts do not reflect our unsecured senior notes payable offering completed on July 18, 2014. Net proceeds of $694 million were used to reduce variable-rate debt, including 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. See Note 13 – Subsequent Events, to our consolidated financial statements (unaudited) appearing elsewhere in this quarterly report on Form 10-Q for further information.

[4] In addition to the stated rate, the unsecured senior line of credit is subject to an annual facility fee of 0.20%.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Background

Background

As used in this quarterly report on Form 10-Q, references to the “Company,” “Alexandria,” “we,” “our,” and “us” refer to Alexandria Real Estate Equities, Inc. and its consolidated subsidiaries.

Alexandria Real Estate Equities, Inc. (NYSE:ARE), with a total market capitalization of approximately $9.3 billion as of June 30, 2014, and an asset base of 31.4 million square feet, including 17.9 million rentable square feet (“RSF”) of operating and current value-creation projects, as well as an additional 13.5 million square feet in future ground-up development projects, is the largest and leading real estate investment trust (“REIT”) uniquely focused on Class A assets in collaborative science and technology campuses located in urban innovation clusters. 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, San Diego, New York City, Maryland, Seattle, and Research Triangle Park. Alexandria is known for its high-quality and diverse client tenant base. Alexandria is the Landlord of Choice to the Life Science Industry^®, and approximately 52% of its total annualized base rent (“ABR”) results 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 collaborative science and technology campuses that provide its client tenants with a highly collaborative, 24/7, live/work/play environment, as well as the critical ability to successfully recruit and retain best-in-class talent. 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 June 30, 2014:

	Square Feet
Operating properties	15,804,327
Development properties	1,879,492
Redevelopment properties	197,289
Total operating and current value-creation projects	17,881,108
Near-term value-creation projects in North America (CIP)	2,474,163
Future value-creation projects	10,760,108
Land subject to sale negotiations	262,950
Total	31,378,329

Ÿ Investment-grade client tenants represented approximately 52% of our total ABR;

Ÿ Approximately 96% of our leases (on an RSF basis) contained effective annual rent escalations that were either fixed (generally ranging from 3% to 3.5%) or indexed based on a consumer price index or other index;

Ÿ Approximately 94% 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;

Ÿ Approximately 93% of our leases (on an RSF basis) provided for the recapture of certain capital expenditures (such as heating, ventilation, and air conditioning (“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.

Noncontrolling Interest [Abstract]

Noncontrolling interests

Noncontrolling interests

Noncontrolling interests represent the third-party interests in certain entities in which we have a controlling interest.  These entities owned 10 properties and three development parcels as of June 30, 2014, 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.

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.  As of June 30, 2014, and December 31, 2013, our redeemable noncontrolling interest balances were $14.4 million and $14.4 million, respectively.  Our remaining noncontrolling interests, aggregating $67.7 million and $47.7 million as of June 30, 2014, and December 31, 2013, respectively, do not have rights to require us to purchase their ownership interests and are classified in total equity in the accompanying consolidated balance sheets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Interest rate swap agreements

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 six months ended June 30, 2014 and 2013, 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 $3.1 million in accumulated other comprehensive loss to interest expense as an increase to interest expense. As of June 30, 2014, and December 31, 2013, the fair values of our interest rate swap agreements aggregating an asset balance were classified in other assets, and those aggregating a liability balance were classified in accounts payable, accrued expenses, and tenant security deposits, based upon their respective fair values. Under our interest rate swap agreements, we have no collateral posting requirements.

As of June 30, 2014, the fair value of derivatives in a net liability position was $2.6 million. 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 at June 30, 2014, it could have been required to settle its obligations under the agreements at their termination value of $2.6 million.

We had the following outstanding interest rate swap agreements that were designated as cash flow hedges of interest rate risk as of June 30, 2014 (dollars in thousands):

Fair Value Disclosures [Abstract]

Fair value measurements

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 and six months ended June 30, 2014 and 2013.

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 June 30, 2014, and December 31, 2013 (in thousands):

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” securities and our interest rate swap agreements, respectively, have been recognized at fair value.  See Note 6 – 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 June 30, 2014, and December 31, 2013, the book and fair values of our “available-for-sale” 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):

Earnings Per Share [Abstract]

Earnings per share

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 earnings per share.  Pursuant to the presentation and disclosure literature on gains or losses on sales or disposals by REITs and earnings per share 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 earnings per share for income from continuing operations.

The land parcels we sold during the three and six months ended June 30, 2014 and 2013, did not meet the criteria for classification as discontinued operations because the land parcels did not have significant operations prior to disposition.  Accordingly, for the three and six months ended June 30, 2014 and 2013, we classified approximately $797 thousand and $772 thousand, respectively, as gain on sale of land parcel below income from discontinued operations, net, in the accompanying consolidated statements of income, and included the gain in income from continuing operations attributable to Alexandria’s common stockholders in the “control number,” or numerator, for computation of earnings per share.

We account for unvested restricted stock awards that contain nonforfeitable rights to dividends as participating securities and include these securities in the computation of earnings per share using the two-class method.  Our Series D cumulative convertible preferred stock (“Series D Preferred Stock”) is not a participating security, and is not included in the computation of earnings per share 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 earnings per share is computed using the weighted average shares of common stock outstanding determined for the basic earnings per share computation plus the effect of any dilutive securities, including the dilutive effect of stock options using the treasury stock method, during the period the securities were outstanding.

The table below is a reconciliation of the numerators and denominators of the basic and diluted earnings per share computations for the three and six months ended June 30, 2014 and 2013 (dollars in thousands, except per share amounts):

Discontinued operations	—			—			—			0.02
Earnings per share – basic and diluted	$	0.39		$	0.38		$	0.85		$	0.74

For purposes of calculating diluted earnings per share, we did not assume conversion of our Series D Preferred Stock for the three and six months ended June 30, 2014 and 2013, since the impact was antidilutive to earnings per share attributable to Alexandria’s common stockholders from continuing operations during those periods.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of presentation

Basis of presentation

We have prepared the accompanying interim consolidated financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) and in conformity with the rules and regulations of the Securities and Exchange Commission (“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, 2014.  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, 2013.

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.

We hold interests, together with certain third parties, in companies that we consolidate in our financial statements. We consolidate the companies because we exercise significant control over major decisions by these entities, such as investment activity and changes in financing.

Reclassifications

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation for discontinued operations.

Use of estimates

Use of estimates

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

Investments in real estate, net, and discontinued operations

Investments in real estate, net, and discontinued operations

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, 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.  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 lives 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 activities 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.  When all of these criteria have been met, the property is classified as “held for sale,” and if (i) the operations and cash flows of the property have been or will be eliminated from the ongoing operations, and (ii) we will not have any significant continuing involvement in the operations of the property after the sale, then its operations, 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.  Depreciation of assets ceases upon designation of a property as “held for sale.”

Impairment of long-lived assets

Impairment of long-lived assets

Long-lived assets to be held and used, including our rental properties, land held for development, construction in progress, 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, land held for development, and construction in progress, are assessed by project and include significant fluctuations in estimated net operating income (“NOI”), 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

Investments

We hold equity investments in certain publicly traded companies and investments in certain privately held entities primarily involved in the life 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 and limited partnerships 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 and limited partnerships are accounted for under the equity method when our interest in the entity is not deemed 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 interest of each individual entity to less than 10%.  As of June 30, 2014, and December 31, 2013, our ownership percentage in the voting interest of each individual entity was less than 10%.

We monitor each of our investments throughout the year for new developments, including operating results, results of clinical trials, capital-raising events, and merger and acquisition activities. Individual investments 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 would 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.

Income Taxes

Income taxes

We are organized and qualify as a REIT pursuant to the Internal Revenue Code of 1986, as amended (the “Code”).  Under the Code, a REIT that distributes 100% of its REIT taxable income as a dividend to its shareholders each year and that meets certain other conditions is not subject to federal income taxes, but could be subject to certain state and local taxes.  We have distributed 100% or more of our taxable income.  Therefore, no provision for federal income taxes is required.  We file tax returns, including returns for our subsidiaries, with federal, state, and local jurisdictions, including jurisdictions located in the United States (“U.S.”), Canada, India, China, and other international locations.  Our tax returns are subject to examination in various jurisdictions for the calendar years 2009 through 2013.

Recognition of rental income and tenant recoveries

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 an asset in 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.

Tenant recoveries related to reimbursement of real estate taxes, insurance, utilities, repairs and maintenance, 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 rent and deferred rent receivables arising from the straight-lining of rent.  As of June 30, 2014, and December 31, 2013, we had no allowance for estimated losses.

Monitoring client tenant credit quality

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 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 life science industry, as well as in finance. This research team is responsible for assessing and monitoring the credit quality of our client tenants and any material changes in credit quality.

Interest income

Interest income

Interest income was $911 thousand and $990 thousand during the three months ended June 30, 2014 and 2013, respectively. Interest income was $1.8 million and $2.3 million during the six months ended June 30, 2014 and 2013, respectively.  Interest income is included in other income in the accompanying consolidated statements of income.

Impact of recently issued accounting standards

Impact of recently issued accounting standards

In April 2014, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) on the reporting of discontinued operations, which raises the threshold for disposals to qualify as discontinued operations. Under this ASU, a discontinued operation is (i) a component of an entity or group of components that has been disposed of by sale, that has been disposed of other than by sale, or that is classified as “held for sale” and represents a strategic shift that has had or will have a major effect on an entity’s operations and financial results or (ii) an acquired business or nonprofit activity that is classified as “held for sale” on the date of the acquisition. A strategic shift that has or will have a major effect on an entity’s operations and financial results could include the disposal of (i) a major line of business, (ii) a major geographic area, (iii) a major equity method investment, or (iv) other major parts of an entity. Under current GAAP, an entity is prohibited from reporting a discontinued operation if it has certain continuing cash flows or involvement with the component after the disposal. This ASU eliminates these criteria and is effective for public companies during the interim and annual periods, beginning after December 15, 2014. We are required to adopt this ASU no later than January 1, 2015 and may early adopt this ASU during interim periods, as applicable. We expect the adoption of this ASU to result in fewer real estate sales qualifying for classification as discontinued operations in our consolidated financial statements.

In May 2014, the FASB issued an ASU that replaces substantially all industry-specific revenue recognition requirements and converges areas under this topic with International Financial Reporting Standards. The ASU implements a five-step process for customer contract revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards. The ASU also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows from contracts with customers. Other major provisions in this ASU include capitalizing and amortizing certain contract costs, ensuring the time value of money is considered in the applicable transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. The ASU is effective for reporting periods beginning after December 15, 2016, and early adoption is prohibited. The ASU does not apply to lease contracts accounted for under current GAAP. We are currently evaluating the impact of the adoption of this ASU will have on our financial position and results of operations.

We hold investments in certain publicly traded companies and privately held entities, including limited partnerships, involved primarily in life science and related industries.  Our investments in publicly traded companies are accounted for as “available for sale” securities and are carried at their fair values.  Investments in “available for sale” securities with gross unrealized losses as of June 30, 2014, 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 have not recognized other-than-temporary impairments related to “available for sale” securities as of June 30, 2014. As of June 30, 2014, and December 31, 2013, there were no unrealized losses in our investments in privately held entities, including limited partnerships.

The following table summarizes our investments as of June 30, 2014, and December 31, 2013 (in thousands):

Condensed consolidating financial information

Condensed consolidating financial information

Alexandria Real Estate Equities, Inc. (the “Issuer”) has sold certain debt securities registered under the Securities Act, 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 June 30, 2014, and December 31, 2013, and the condensed consolidating statements of income and comprehensive income for the three and six months ended June 30, 2014 and 2013, and condensed consolidating cash flows for the six months ended June 30, 2014 and 2013, for the Issuer, the Guarantor Subsidiary, the Combined Non-Guarantor Subsidiaries, 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.
