EXPLANATORY NOTE REGARDING THIS AMENDMENT

The sole purpose of this Amendment No. 1 on Form 10-Q/A (this “Amendment”) to BioMed Realty Trust, Inc.'s and BioMed Realty, L.P.'s Quarterly Report on Form 10-Q for the quarter ended March 31, 2012, filed with the Securities and Exchange Commission on May 2, 2012 (the “Original Filing”), is to re-file the Original Filing under both BioMed Realty Trust, Inc. and BioMed Realty, L.P.  The Original Filing was filed solely under BioMed Realty Trust, Inc.

No amendments have been made to the Original Filing in this Amendment.  This Amendment does not reflect events occurring after May 2, 2012, the date of the Original Filing, or modify or update those disclosures that may have been affected by subsequent events.  

EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the quarter ended March 31, 2012 of BioMed Realty Trust, Inc., a Maryland corporation, and BioMed Realty, L.P., a Maryland limited partnership of which BioMed Realty Trust, Inc. is the parent company and general partner. Unless otherwise indicated or unless the context requires otherwise, all references in this report to “we,” “us,” “our” or “our company” refer to BioMed Realty Trust, Inc. together with its consolidated subsidiaries, including BioMed Realty, L.P. Unless otherwise indicated or unless the context requires otherwise, all references in this report to “our operating partnership” or “the operating partnership” refer to BioMed Realty, L.P. together with its consolidated subsidiaries.

BioMed Realty Trust, Inc. operates as a real estate investment trust, or REIT, and the general partner of BioMed Realty, L.P. As of March 31, 2012, BioMed Realty Trust, Inc. owned an approximate 98.1% partnership interest and other limited partners, including some of our directors, executive officers and their affiliates, owned the remaining 1.9% partnership interest (including long term incentive plan units) in BioMed Realty, L.P. As the sole general partner of BioMed Realty, L.P., BioMed Realty Trust, Inc. has the full, exclusive and complete responsibility for the operating partnership's day-to-day management and control.

There are a few differences between our company and our operating partnership, which are reflected in the disclosure in this report. We believe it is important to understand the differences between our company and our operating partnership in the context of how BioMed Realty Trust, Inc. and BioMed Realty, L.P. operate as an interrelated consolidated company. BioMed Realty Trust, Inc. is a REIT, whose only material asset is its ownership of partnership interests of BioMed Realty, L.P. As a result, BioMed Realty Trust, Inc. does not conduct business itself, other than acting as the sole general partner of BioMed Realty, L.P., issuing public equity from time to time and guaranteeing certain debt of BioMed Realty, L.P. BioMed Realty Trust, Inc. itself does not hold any indebtedness but guarantees some of the secured and unsecured debt of BioMed Realty, L.P. BioMed Realty, L.P. holds substantially all the assets of the company and holds the ownership interests in the company's joint ventures. BioMed Realty, L.P. conducts the operations of the business and is structured as a partnership with no publicly traded equity. Except for net proceeds from public equity issuances by BioMed Realty Trust, Inc., which are generally contributed to BioMed Realty, L.P. in exchange for partnership units, BioMed Realty, L.P. generates the capital required by the company's business through BioMed Realty, L.P.'s operations, by BioMed Realty, L.P.'s direct or indirect incurrence of indebtedness or through the issuance of partnership units.

Noncontrolling interests and stockholders' equity and partners' capital are the main areas of difference between the consolidated financial statements of BioMed Realty Trust, Inc. and those of BioMed Realty, L.P. The operating partnership and long term incentive plan units in BioMed Realty, L.P. that are not owned by BioMed Realty Trust, Inc. are accounted for as partners' capital in BioMed Realty, L.P.'s financial statements and as noncontrolling interests in BioMed Realty Trust, Inc.'s financial statements. The noncontrolling interests in BioMed Realty, L.P.'s financial statements include the interests of joint venture partners. The noncontrolling interests in BioMed Realty Trust, Inc.'s financial statements include the same noncontrolling interests at the BioMed Realty, L.P. level as well as the limited partnership unitholders of BioMed Realty, L.P., not including BioMed Realty Trust, Inc. The differences between stockholders' equity and partners' capital result from the differences in the equity issued at the BioMed Realty Trust, Inc. and the BioMed Realty, L.P. levels.

We believe combining the quarterly reports on Form 10-Q of BioMed Realty Trust, Inc. and BioMed Realty, L.P. into this single report:

• better reflects how management and the analyst community view the business as a single operating unit,

• enhances investor understanding of our company by enabling them to view the business as a whole and in the same manner as management,

3

• is more efficient for our company and results in savings in time, effort and expense, and

• is more efficient for investors by reducing duplicative disclosure and providing a single document for their review.

To help investors understand the significant differences between our company and our operating partnership, this report presents the following separate sections for each of BioMed Realty Trust, Inc. and BioMed Realty, L.P.:

• consolidated financial statements,

• the following notes to the consolidated financial statements:

• Equity / Partners' Capital,

• Debt, and

• Earnings Per Share / Unit,

• Liquidity and Capital Resources in Management's Discussion and Analysis of Financial Condition and Results of

Operations, and

• Unregistered Sales of Equity Securities and Use of Proceeds.

This report also includes separate Item 4. Controls and Procedures sections and separate Exhibit 31 and 32 certifications for each of BioMed Realty Trust, Inc. and BioMed Realty, L.P. in order to establish that the Chief Executive Officer and the Chief Financial Officer of BioMed Realty Trust, Inc. have made the requisite certifications and BioMed Realty Trust, Inc. and BioMed Realty, L.P. are compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934 and 18 U.S.C. §1350.

BIOMED REALTY TRUST, INC.

BIOMED REALTY, L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Organization of the Parent Company and Description of Business

BioMed Realty Trust, Inc., a Maryland corporation (the “Parent Company”), operates as a fully integrated, self-administered and self-managed real estate investment trust (“REIT”) focused on acquiring, developing, owning, leasing and managing laboratory and office space for the life science industry principally through its subsidiary, BioMed Realty, L.P., a Maryland limited partnership (the “Operating Partnership” and together with the Parent Company referred to as the “Company”). The Company's tenants primarily include biotechnology and pharmaceutical companies, scientific research institutions, government agencies and other entities involved in the life science industry. The Company's properties are generally located in markets with well-established reputations as centers for scientific research, including Boston, San Francisco, San Diego, Maryland, New York/New Jersey, Pennsylvania and Seattle.

The Parent Company is the sole general partner of the Operating Partnership and, as of March 31, 2012, owned a 98.1% interest in the Operating Partnership. The remaining 1.9% interest in the Operating Partnership is held by limited partners. Each partner's percentage interest in the Operating Partnership is determined based on the number of operating partnership units and long-term incentive plan units (“LTIP units” and together with the operating partnership units, the “OP units”) owned as compared to total OP units (and potentially issuable OP units, as applicable) outstanding as of each period end and is used as the basis for the allocation of net income or loss to each partner.

2. Basis of Presentation and Summary of Significant Accounting Policies

The accompanying interim financial statements are unaudited, but have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in conjunction with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all the disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments and eliminations, consisting of normal recurring adjustments necessary for a fair presentation of the financial statements for these interim periods have been recorded. These financial statements should be read in conjunction with the audited consolidated financial statements and notes therein included in the Company's annual report on Form 10-K for the year ended December 31, 2011.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, partnerships and limited liability companies it controls, and variable interest entities for which the Company has determined itself to be the primary beneficiary. All material intercompany transactions and balances have been eliminated. The Company consolidates entities the Company controls and records a noncontrolling interest for the portions not owned by the Company. Control is determined, where applicable, by the sufficiency of equity invested and the rights of the equity holders, and by the ownership of a majority of the voting interests, with consideration given to the existence of approval or veto rights granted to the minority stockholder. If the minority stockholder holds substantive participating rights, it overcomes the presumption of control by the majority voting interest holder. In contrast, if the minority stockholder simply holds protective rights (such as consent rights over certain actions), it does not overcome the presumption of control by the majority voting interest holder.

Investments in Partnerships and Limited Liability Companies

The Company has determined that it is the primary beneficiary in six variable interest entities, or VIEs, consisting of single-tenant properties in which the tenant has a fixed-price purchase option, which are consolidated and reflected in the accompanying consolidated financial statements. Selected financial data of the VIEs at March 31, 2012 and December 31, 2011 consist of the following (in thousands):

Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed

The Company reviews long-lived assets and certain identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The review of recoverability is based on an estimate of the future undiscounted cash flows (excluding interest charges) expected to result from the long-lived asset's use and eventual disposition. These cash flows consider factors such as expected future operating income, trends and prospects, as well as the effects of leasing demand, competition and other factors. If impairment exists due to the inability to recover the carrying value of a long-lived asset, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair-value of the property. The Company is required to make subjective assessments as to whether there are impairments in the values of its investments in long-lived assets. These assessments have a direct impact on the Company's net income because recording an impairment loss results in an immediate negative adjustment to net income. The evaluation of anticipated cash flows is highly subjective and is based in part on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results in future periods. Although the Company's strategy is to hold its properties over the long-term, if the Company's strategy changes or market conditions otherwise dictate an earlier sale date, an impairment loss may be recognized to reduce the property to the lower of the carrying amount or fair-value, and such loss could be material.

In April 2012, the Company completed the exchange of a property for another real estate operating property. As a result, as of March 31, 2012, the property being disposed of was reclassified as held for sale. This property was written down to its estimated fair-value of $28.0 million, less costs to sell, which resulted in an impairment loss of $4.6 million, which is included in loss from discontinued operations, for the three months ended March 31, 2012. The parties to the exchange determined and agreed upon the fair-value of the property received in the transaction, which we consider to be a level 2 input in the fair value hierarchy. See Note 11 for discussion of discontinued operations.

Deferred Leasing Costs, Net

Deferred leasing costs, net of accumulated amortization at March 31, 2012 consisted of the following (in thousands):

	Balance at		Accumulated
	March 31, 2012		Amortization			Net
Acquired in-place leases	$	272,330	$	(158,499	)	$	113,831

	$	337,709	$	(180,454	)	$	157,255

Investments

Investments in equity securities, which are included in other assets on the accompanying consolidated balance sheets, consisted of the following (in thousands):

	March 31, 2012			December 31, 2011
Available-for-sale securities, historical cost	$	5,298		$	5,585
Other-than-temporary unrealized loss	(4,359		)	(4,595		)
Unrealized loss	(239		)	(2		)
Available-for-sale securities, fair-value(1)	700			988
Privately-held securities, cost basis	5,370			4,245
Total equity securities	$	6,070		$	5,233

____________

(1) Determination of fair-value is classified as Level 1 in the fair-value hierarchy based on the use of quoted prices in active markets.

The Company's investments in available-for-sale securities of two publicly traded companies currently have fair-values that are less than the Company's cost basis, net of previous other-than-temporary impairment in these securities due to decreases in their respective stock prices during the three months endedMarch 31, 2012. However, management has the intent and ability to retain the investments for a period of time sufficient to allow for an anticipated recovery in market value. Management will continue to periodically evaluate whether any investment, the fair-value of which is less than the Company's cost basis, should be considered other-than-temporarily-impaired. If other-than-temporary impairment is considered to exist, the related unrealized loss will be reclassified from accumulated other comprehensive loss and recorded as a reduction of net income.

The Company's remaining investments consisted of securities in privately-held companies or funds, which are recorded at cost basis due to the Company's lack of control or significant influence over such companies or funds. The Company owned equity securities of three privately-held companies and two privately-held funds during the three months endedMarch 31, 2012. There were no identified events or changes in circumstances that may have a significant adverse effect on the carrying value of the Company's cost basis investments and therefore, no evaluation of impairment was performed during the three months endedMarch 31, 2012 on the Company's cost basis investments.

Management's Estimates

Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reporting of revenue and expenses during the reporting period to prepare these consolidated financial statements in conformity with GAAP. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and reported amounts of revenue and expenses that are not readily apparent from other sources. Actual results could differ from those estimates under different assumptions or conditions.

3. Equity of the Parent Company

During the three months endedMarch 31, 2012, the Parent Company issued restricted stock awards to the Company's employees totaling 218,911 shares of common stock (180,525 shares of common stock were surrendered to the Company and subsequently retired in lieu of cash payments for taxes due on the vesting of restricted stock during the same period), which are included in the total of common stock outstanding as of the period end.

During the three months endedMarch 31, 2012, the Parent Company awarded 408,888 performance units (the “Performance Units”) to certain of its executive officers, which represent the maximum number of Performance Units that may vest. Each Performance Unit represents a contingent right to receive one share of the Parent Company's common stock if vesting conditions are satisfied. Performance Units vest ratably over one, two and three year periods (each, a “Performance Period”) based upon the Parent Company's total stockholder return relative to its peer group. The grant date fair-value of the Performance Units was estimated using a Monte Carlo simulation which considered the likelihood of achieving the vesting conditions. The grant date fair-value of these awards of approximately $3.3 million will be recognized as compensation expense on a straight-line basis over each respective Performance Period. The total compensation to be expensed in future periods as of March 31, 2012 was $3.0 million over a weighted-average of approximately 1.8 years. No dividends will be paid or accrued on the Performance Units, and shares of the Parent Company's common stock will not be issued until vesting of the Performance Units occurs.

Common Stock, Operating Partnership Units and LTIP Units

As of March 31, 2012, the Company had outstanding 154,163,339 shares of the Parent Company's common stock and 2,593,538 and 362,970 operating partnership and LTIP units, respectively. A share of the Parent Company's common stock and the operating partnership and LTIP units have essentially the same economic characteristics as they share equally in the total net income or loss and distributions of the Operating Partnership.

Dividends and Distributions

The following table lists the dividends and distributions declared by the Parent Company and the Operating Partnership during the three months endedMarch 31, 2012:

Declaration Date	Securities Class	Amount Per Share/Unit		Period Covered	Dividend and Distribution Payable Date	Dividend and Distribution Amount
						(In thousands)
March 15, 2012	Common stock and OP units	$	0.21500	January 1, 2012 to March 31, 2012	April 16, 2012	$	33,781
March 15, 2012	Series A preferred stock/units	$	0.46094	January 16, 2012 to April 15, 2012	April 16, 2012	$	3,651

Total 2012 dividends and distributions declared through March 31, 2012 (in thousands):

Common stock and OP units	$	33,781
Series A preferred stock/units	3,651
	$	37,432

Noncontrolling Interests

Noncontrolling interests on the consolidated balance sheets of the Parent Company relate primarily to the OP units in the Operating Partnership that are not owned by the Parent Company. With respect to the noncontrolling interests in the Operating Partnership, noncontrolling interests with redemption provisions that permit the issuer to settle in either cash or common stock at the option of the issuer are further evaluated to determine whether temporary or permanent equity classification on the balance sheet is appropriate. Because the OP units comprising the noncontrolling interests contain such a provision, the Company evaluated this guidance, including the requirement to settle in unregistered shares, and determined that the OP units meet the requirements to qualify for presentation as permanent equity.

The Company evaluates individual redeemable noncontrolling interests for the ability to continue to recognize the noncontrolling interest as permanent equity in the consolidated balance sheets. Any redeemable noncontrolling interest that fails to qualify as permanent equity will be reclassified as temporary equity and adjusted to the greater of (1) the carrying amount, or (2) its redemption value at the end of the period in which the determination is made.

The redemption value of the OP units not owned by the Parent Company, had such units been redeemed at March 31, 2012, was approximately $56.4 million based on the average closing price of the Parent Company's common stock of $19.07 per share for the ten consecutive trading days immediately preceding March 31, 2012.

The following table shows the vested ownership interests in the Operating Partnership were as follows:

	March 31, 2012			December 31, 2011
	Operating Partnership Units and LTIP Units	Percentage of Total		Operating Partnership Units and LTIP Units	Percentage of Total
BioMed Realty Trust	152,814,354	98.1	%	152,435,271	98.1	%
Noncontrolling interest consisting of:
Operating partnership and LTIP units held by employees and related parties	2,339,314	1.5	%	2,332,318	1.5	%
Operating partnership and LTIP units held by third parties	588,801	0.4	%	588,801	0.4	%
Total	155,742,469	100.0	%	155,356,390	100.0	%

4. Capital of the Operating Partnership

Operating Partnership Units and LTIP Units

As of March 31, 2012, the Operating Partnership had outstanding 156,756,877 operating partnership units and 362,970 LTIP units. The Parent Company owned 98.1% of the partnership interests in the Operating Partnership at March 31, 2012, is the Operating Partnership's general partner and is responsible for the management of the Operating Partnership's business. As the general partner of the Operating Partnership, the Parent Company effectively controls the ability to issue common stock of the Parent Company upon a limited partner's notice of redemption. In addition, the general partner of the Operating Partnership has generally acquired OP units upon a limited partner's notice of redemption in exchange for shares of the Parent Company's common stock. The redemption provisions of OP units owned by limited partners that permit the issuer to settle in either cash or common stock at the option of the issuer are further evaluated in accordance with applicable accounting guidance to determine whether temporary or permanent equity classification on the balance sheet is appropriate. The Operating Partnership evaluated this guidance, including the requirement to settle in unregistered shares, and determined that these OP units meet the requirements to qualify for presentation as permanent equity.

The redemption value of the OP units owned by the limited partners, not including the Parent Company, had such units been redeemed at March 31, 2012, was approximately $56.4 million based on the average closing price of the Parent Company's common stock of $19.07 per share for the ten consecutive trading days immediately preceding March 31, 2012.

5. Debt

Debt of the Parent Company

The Parent Company does not hold any indebtedness. All debt is held directly or indirectly by the Operating Partnership; however, the Parent Company has guaranteed the Operating Partnership's Exchangeable Senior Notes due 2030 (the “Notes due 2030”), Unsecured Senior Notes due 2016 (the “Notes due 2016”), Unsecured Senior Notes due 2020 (the “Notes due 2020”), Unsecured Senior Term Loan (the “Term Loan”) and unsecured line of credit.

____________

(1) During the three months endedMarch 31, 2012, the Operating Partnership repaid in full the outstanding mortgage notes totaling approximately $26.2 million pertaining to the Sidney Street property resulting in a gain on extinguishment, representing the write-off of unamortized debt premium, partially offset by the write-off of deferred loan fees, which is included in other income / (expense).

(2) The unamortized debt discount will be amortized through April 15, 2016, the maturity date of the Notes due 2016.

(3) The unamortized debt discount will be amortized through April 15, 2020, the maturity date of the Notes due 2020.

(4) The effective interest rate includes the impact of interest rate swap agreements (see Note 9 for further discussion of interest rate swap agreements).

(5) At March 31, 2012, the Operating Partnership had additional borrowing capacity under the unsecured line of credit of up to approximately $723.1 million (net of outstanding letters of credit issued by the Operating Partnership and drawable on the unsecured line of credit of approximately $910,000). During the three months endedMarch 31, 2012, the Operating Partnership amended the credit agreement governing the unsecured line of credit, which provides for a revision to the definition of “gross asset value” to conform to the definition included in the Term Loan credit facility and certain other revisions to reflect the existence of the Term Loan, including changes pertaining to cross-default provisions and negative pledge restrictions. All other material terms under the credit agreement governing the unsecured line of credit remain unchanged.

Unsecured Senior Term Loan

On March 30, 2012, the Operating Partnership entered into a $400.0 million Term Loan with KeyBank National Association as Administrative Agent and Co-Lead Arranger, Wells Fargo Securities, LLC as Co-Lead Arranger and Wells Fargo Bank National Association as Co-Syndication Agent, U.S. Bank National Association as Co-Syndication Agent and Co-Lead Arranger and other lenders. The Term Loan has a maturity date of March 30, 2017. Subject to the Administrative Agent's reasonable discretion, the Operating Partnership may increase the amount of the borrowings to $500.0 million under the Term Loan upon satisfying certain conditions. Borrowings under the Term Loan are guaranteed by the Parent Company.

7

Borrowings under the Term Loan bear interest at a floating rate equal to, at the Operating Partnership's option, either (1) reserve adjusted LIBOR plus a spread which ranges from 115 to 205 basis points, depending on the Company's credit ratings, or (2) the highest of (a) the prime rate then in effect plus a spread which ranges from 15 to 120 basis points, (b) the federal funds rate then in effect plus a spread which ranges from 65 to 170 basis points or (c) one-month LIBOR plus a spread which ranges from 115 to 205 basis points, in each case, depending on the Parent Company's credit ratings.

Concurrent with the closing of the Term Loan the Operating Partnership entered into interest rate swap agreements, which are intended to have the effect of fixing interest payments associated with $200.0 million of the $400.0 million outstanding under the Term Loan at approximately 2.81% for a five-year term, subject to change depending on the Parent Company's credit ratings.

The Term Loan includes certain restrictions and covenants which require compliance with financial covenants relating to the minimum amounts of net worth, fixed charge coverage, unsecured debt service coverage, overall leverage and unsecured leverage ratios, the maximum amount of secured indebtedness and certain investment limitations. The Term Loan specifies a number of events of default (some of which are subject to applicable cure periods), including, among others, the failure to make payments when due, noncompliance with covenants and defaults under other agreements or instruments of indebtedness. Upon the occurrence of an event of default, the lenders may terminate the Term Loan and declare all amounts outstanding to be immediately due and payable. Management believes that it was in compliance with the covenants as of March 31, 2012.

As of March 31, 2012, principal payments due for the Operating Partnership's consolidated indebtedness (excluding debt premiums and discounts) were as follows (in thousands):

2012	$	12,159
2013	8,291
2014	339,020
2015	32,253
2016	543,426
Thereafter(1)	877,109
	$	1,812,258

____________

(1) Includes $180.0 million in principal payments of the Notes due 2030 based on a contractual maturity date of January 15, 2030.

6. Earnings Per Share of the Parent Company

Through March 31, 2012 all of the Company's participating securities (including the OP units) received dividends/distributions at an equal dividend/distribution rate per share/unit. As a result, the portion of net income allocable to the weighted-average restricted stock outstanding for the three months endedMarch 31, 2012 and 2011 has been deducted from net income available to common stockholders to calculate basic earnings per share. The calculation of diluted earnings per share for the three months endedMarch 31, 2012 and 2011 includes the outstanding OP units (both vested and unvested) in the weighted-average shares, and net income attributable to noncontrolling interests in the Operating Partnership has been added back to net income available to common stockholders. For the three months endedMarch 31, 2012, the Performance Units were anti-dilutive to the calculation of diluted earnings per share as calculated, assuming that March 31, 2012 is the end of the Performance Units' Performance Period. For the three months endedMarch 31, 2012 and 2011, the restricted stock was anti-dilutive to the calculation of diluted earnings per share and was therefore excluded. As a result, diluted earnings per share was calculated based upon net income available to common stockholders less net income allocable to unvested restricted stock and distributions in excess of earnings attributable to unvested restricted stock. No shares were issuable upon settlement of the excess exchange value pursuant to the exchange settlement feature of the Operating Partnership's Exchangeable Senior Notes due 2026 (the “Notes due 2026”) as the common stock price at March 31, 2011 did not exceed the exchange price then in effect. In addition, shares issuable upon settlement of the exchange feature of the Notes due 2030 were anti-dilutive and were not included in the calculation of diluted earnings per share based on the “if converted” method for the three months endedMarch 31, 2012 and 2011. No other shares were considered anti-dilutive for the three months endedMarch 31, 2012 and 2011.

Computations of basic and diluted earnings per share (in thousands, except share data) were as follows:

	Three Months Ended

7. Earnings Per Unit of the Operating Partnership

Through March 31, 2012 all of the Operating Partnership's participating securities received distributions at an equal distribution rate per unit. As a result, the portion of net income allocable to the weighted-average unvested OP units outstanding for the three months endedMarch 31, 2012 and 2011 has been deducted from net income available to unitholders to calculate basic earnings per unit. For the three months endedMarch 31, 2012 and 2011 the unvested OP units were anti-dilutive to the calculation of earnings per unit and were therefore excluded from the calculation of diluted earnings per unit, and diluted earnings per unit is calculated based upon net income attributable to unitholders. For the three months endedMarch 31, 2012, the Performance Units were anti-dilutive to the calculation of diluted earnings per share as calculated, assuming that March 31, 2012 is the end of the Performance Units' Performance Period. No shares of common stock of the Parent Company were contingently issuable upon settlement of the excess exchange value pursuant to the exchange settlement feature of the Notes due 2026 as the common stock price at March 31, 2011 did not exceed the exchange price then in effect. In addition, units issuable upon settlement of the exchange feature of the Notes due 2030 were anti-dilutive and were not included in the calculation of diluted earnings per unit based on the “if converted” method for the three months endedMarch 31, 2012 and 2011. No other units were considered anti-dilutive for the three months endedMarch 31, 2012 and 2011.

Computations of basic and diluted earnings per unit (in thousands, except share data) were as follows:

8. Investment in Unconsolidated Partnerships

The accompanying consolidated financial statements include investments in two limited liability companies with Prudential Real Estate Investors (“PREI”), and in 10165 McKellar Court, L.P. (“McKellar Court”), a limited partnership with Quidel Corporation, the tenant which occupies the McKellar Court property.

9. Derivatives and Other Financial Instruments

On March 30, 2012, the Company entered into four interest rate swaps with an aggregate notional amount of $200.0 million under which at each monthly settlement date the Company either (1) receives the difference between a fixed interest rate (the “Strike Rate”) and one-month LIBOR if the Strike Rate is less than one-month LIBOR or (2) pays such difference if the Strike Rate is greater than one-month LIBOR. The interest rate swaps hedge the Company's exposure to the variability on expected cash flows attributable to changes in interest rates on the first interest payments, due on the date that is on or closest after each swap's settlement date, associated with the amount of one-month LIBOR-based debt equal to each swap's notional amount. These interest rate swaps, with a notional amount of $200.0 million, are currently intended to hedge interest payments associated with the Operating Partnership's Term Loan. No initial investment was made to enter into the interest rate swap agreements.

As of March 31, 2012, the Company had deferred interest costs of approximately $47.4 million in accumulated other comprehensive loss related to forward starting swaps, which were settled with the corresponding counterparties in March and April 2009. The forward starting swaps were entered into to mitigate the Company's exposure to the variability in expected future cash flows attributable to changes in future interest rates associated with a forecasted issuance of fixed-rate debt, with interest payments for a minimum of ten years. The deferred interest costs will be amortized as additional interest expense over a remaining period of approximately seven years.

The following is a summary of the terms of the interest rate swaps and stock purchase warrants and their respective fair-values, which are included in derivative instruments on the accompanying consolidated balance sheets (dollars in thousands):

8

	Notional Amount						Fair-Value(1)
			Strike Rate		Effective Date	Expiration Date	March 31, 2012			December 31, 2011
	$	75,000	1.163	%	March 30, 2012	March 30, 2017	$	(88	)	$	—
	50,000		1.163	%	March 30, 2012	March 30, 2017	(39		)	—
	50,000		1.163	%	March 30, 2012	March 30, 2017	(97		)	—
	25,000		1.163	%	March 30, 2012	March 30, 2017	(65		)	—
Interest rate swaps	200,000						(289		)	—
Other(2)	—						1			9
Total derivative instruments	$	200,000					$	(288	)	$	9

____________

(1) Fair-value of derivative instruments does not include any related accrued interest payable, which is included in accrued expenses on the accompanying consolidated balance sheets. Derivative valuations are classified in Level 2 of the fair-value hierarchy.

(2) Includes stock purchase warrants recorded as derivative instruments. Changes in the fair-values of stock purchase warrants are included in earnings in the period in which they occur.

For derivatives designated as cash flow hedges, the effective portion of changes in the fair-value of the derivative is initially reported in accumulated other comprehensive income (outside of earnings) and subsequently reclassified to earnings in the period in which the hedged forecasted transaction affects earnings. During the three months endedMarch 31, 2012, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt and future variability in the interest-related cash flows from forecasted issuances of debt. The ineffective portion of the change in fair-value of the derivatives is recognized directly in earnings.

The Company's use of proceeds from its March 2011 unsecured debt offering to repay a portion of the outstanding indebtedness on its unsecured line of credit caused the amount of variable-rate indebtedness to fall below the combined notional value of the outstanding interest rate swaps on March 30, 2011, causing the Company to be overhedged. As a result, the Company re-performed tests to assess the effectiveness of its interest rate swaps. Although the interest rate swaps with an aggregate notional amount of $150.0 million passed the assessment tests and the $115.0 million swap continued to qualify for hedge accounting, the $35.0 million swap no longer qualified for hedge accounting due to the lack of variable rate debt expected to be outstanding during the remaining term of the swap. As a result, the Company accelerated the reclassification of amounts deferred in accumulated other comprehensive loss to earnings related to the hedged forecasted transactions that became probable of not occurring during the period in which the Company was overhedged. From the date that hedge accounting was discontinued on the $35.0 million swap, changes in the fair-value associated with this interest rate swap were recorded directly to earnings, resulting in the recognition of a gain of approximately $31,000 for the three months ended March 31, 2011, which is included as a component of loss on derivative instruments. These swaps expired in August 2011.

During the three months ended March 31, 2012, the Company recorded total losses on derivative instruments of $8,000, primarily related to changes in the fair-value of stock purchase warrants. During the three months endedMarch 31, 2011, the Company recognized a loss of approximately $1.0 million primarily related to the reduction in the amount of the variable-rate indebtedness relating to the remaining $150.0 million interest rate swaps (see above), hedge ineffectiveness on cash flow hedges due to mismatches in maturity dates and interest rate reset dates between the interest rate swaps and corresponding debt and changes in the fair-value of other derivative instruments.

Amounts reported in accumulated other comprehensive loss related to derivatives will be reclassified to earnings during the period in which the hedged forecasted transaction affects earnings. The change in net unrealized (loss) / gain on derivative instruments includes reclassifications of net unrealized losses from accumulated other comprehensive loss as (1) an increase to interest expense of $1.8 million and $3.4 million for the three months endedMarch 31, 2012 and 2011, respectively, and (2) a loss on derivative instruments, which is included in other income / (expense), of $8,000 and $1.0 million for the three months endedMarch 31, 2012 and 2011, respectively. During the next twelve months, the Company estimates that an additional $8.5 million will be reclassified from accumulated other comprehensive loss as an increase to interest expense.

The following is a summary of the amount of loss recognized in other comprehensive income related to the derivative instruments (in thousands):

	Three Months Ended
	March 31,
	2012			2011

Total loss on derivative instruments	$	(8	)	$	(1,011	)

____________

(1) Amount represents payments made to swap counterparties for the effective portion of interest rate swaps that were recognized as an increase to interest expense for the periods presented (the amount was recorded as an increase and corresponding decrease to accumulated other comprehensive loss in the same accounting period).

(2) Amount represents reclassifications of deferred interest costs from accumulated other comprehensive loss to interest expense related to the Company's previously settled forward starting swaps.

10. Fair-Value of Financial Instruments

The Company's disclosures of estimated fair-value of financial instruments at March 31, 2012 and December 31, 2011 were determined using available market information and appropriate valuation methods. Considerable judgment is necessary to interpret market data and develop estimated fair-value. The use of different market assumptions or estimation methods may have a material effect on the estimated fair-value amounts.

The carrying amounts for cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other liabilities approximate fair-value due to the short-term nature of these instruments.

The Company utilizes quoted market prices to estimate the fair-value of its fixed-rate and variable-rate debt, when available. If quoted market prices are not available, the Company calculates the fair-value of its mortgage notes payable and other fixed-rate debt based on a currently available market rate assuming the loans are outstanding through maturity and considering the collateral. In determining the current market rate for fixed-rate debt, a market credit spread is added to the quoted yields on federal government treasury securities with similar terms to debt. In determining the current market rate for variable-rate debt, a market credit spread is added to the current effective interest rate. The carrying values of interest rate swaps are reflected at their fair-values. The Company receives quotations from a third party to use in estimating these fair-values.

At March 31, 2012 and December 31, 2011, the aggregate fair-value and the carrying value of the Company's financial instruments were as follows (in thousands):

	March 31, 2012						December 31, 2011
	Fair-Value (1)			Carrying Value			Fair-Value (1)		Carrying Value
Mortgage notes payable, net	$	632,072		$	559,111		$	670,931	$	587,844

Derivative instruments (2)	(288		)	(288		)	9		9
Available-for-sale securities	700			700			988		988

____________

(1) Fair-values of debt and derivative instruments are classified in Level 2 of the fair-value hierarchy. Fair-value of available-for-sale securities are classified in Level 1 of the fair-value hierarchy.

(2) The Company's derivative instruments are reflected in other assets and other liabilities on the accompanying consolidated balance sheets based on their respective balances (see Note 9).

11. Discontinued Operations

In April 2012, the Company completed the exchange of an operating property on Forbes Boulevard in South San Francisco for an office property located in Redwood City, California. As a result, during the three months endedMarch 31, 2012, the Company reclassified the Forbes Boulevard property as held for sale. The table below reflects the details of the property held for sale and the exchange (in thousands):

Property	Date of Sale	Original Acquisition Date	Sales Price (1)		Impairment loss
Forbes Boulevard	April 27, 2012	September 5, 2007	$	28,000	$	(4,552	)

_________

(1) The sales price was equal to the fair-value of the office property received as consideration for the exchange from the independent third party. As of March 31, 2012, the assets associated with the Forbes Boulevard property held for sale of $28.0 million are classified within other assets in the accompanying consolidated balance sheets. As of March 31, 2012, there are no significant liabilities related to the Forbes property.

The results of operations of the Forbes Boulevard property are reported as discontinued operations for all periods presented in the accompanying consolidated financial statements. The following table summarizes the revenue and expense components that comprise (loss) / income from discontinued operations (in thousands):

	Three Months Ended
	March 31,
	2012			2011
Total revenues	$	351		$	352
Total expenses	219			211
Income from discontinued operations before loss on impairment	132			141
Impairment loss	(4,552		)	—
(Loss) / income from discontinued operations	$	(4,420	)	$	141

Discontinued operations have not been segregated in the consolidated statements of cash flows. Therefore, amounts for certain captions will not agree with respective data in the consolidated statements of operations.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTSOF OPERATIONS

As used herein, the terms “we,” “us,” “our” or the “Company” refer to BioMed Realty Trust, Inc., a Maryland corporation, and any of our subsidiaries, including BioMed Realty, L.P., a Maryland limited partnership of which BioMed Realty Trust, Inc.

10

is the parent company and general partner, which may be referred to herein as the “operating partnership.”

The following discussion should be read in conjunction with the consolidated financial statements and notes thereto appearing elsewhere in this report. We make statements in this report that are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. In particular, statements pertaining to our capital resources, portfolio performance and results of operations contain forward-looking statements. Forward-looking statements involve numerous risks and uncertainties and you should not rely on them as predictions of future events. Forward-looking statements depend on assumptions, data or methods which may be incorrect or imprecise, and we may not be able to realize them. We do not guarantee that the transactions and events described will happen as described (or that they will happen at all). You can identify forward-looking statements by the use of forward-looking terminology such as “believes,” “expects,” “may,” “will,” “should,” “seeks,” “approximately,” “intends,” “plans,” “estimates” or “anticipates” or the negative of these words and phrases or similar words or phrases. You can also identify forward-looking statements by discussions of strategy, plans or intentions. The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements: adverse economic or real estate developments in the life science industry or in our target markets, including the inability of our tenants to obtain funding to run their businesses; reductions in asset valuations and related impairment charges; our dependence upon significant tenants; our failure to obtain necessary outside financing on favorable terms or at all, including the continued availability of our unsecured line of credit; general economic conditions, including downturns in the national and local economies; volatility in financial and securities markets; defaults on or non-renewal of leases by tenants; our inability to compete effectively; increased interest rates and operating costs; our inability to successfully complete real estate acquisitions, developments and dispositions; risks and uncertainties affecting property development and construction; our failure to successfully operate acquired properties and operations; the loss of services of one or more of our executive officers; our failure to qualify or continue to qualify as a REIT; failure to maintain our investment grade credit ratings with the rating agencies; government approvals, actions and initiatives, including the need for compliance with environmental requirements; the effects of earthquakes and other natural disasters; lack of or insufficient amounts of insurance; and changes in real estate, zoning and other laws and increases in real property tax rates. We disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

The risks included here are not exhaustive, and additional factors could adversely affect our business and financial performance, including factors and risks included in other sections of this report. In addition, we discussed a number of material risks in our annual report on Form 10-K for the year ended December 31, 2011. Those risks continue to be relevant to our performance and financial condition. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to predict all such risk factors, nor can it assess the impact of all such risk factors on our company's business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results.

Overview

We operate as a fully integrated, self-administered and self-managed REIT focused on acquiring, developing, owning, leasing and managing laboratory and office space for the life science industry. Our tenants primarily include biotechnology and pharmaceutical companies, scientific research institutions, government agencies and other entities involved in the life science industry. Our properties are generally located in markets with well-established reputations as centers for scientific research, including Boston, San Francisco, San Diego, Maryland, New York/New Jersey, Pennsylvania, and Seattle.

At March 31, 2012, we owned or had interests in a portfolio with an aggregate of approximately 12.4 million rentable square feet, excluding properties classified as held for sale.

The following reflects the classification of our properties, excluding properties held for sale, between stabilized properties (operating properties in which more than 90% of the rentable square footage is under lease), lease up properties (operating properties in which less than 90% of the rentable square footage is under lease), long-term lease up properties (our Pacific Industrial Center, Pacific Research Center North and Pacific Research Center South properties), redevelopment properties (properties that are currently being prepared for their intended use), unconsolidated partnership properties (properties which we partially own, but are not included in our consolidated financial statements) and development potential (representing management's estimates of rentable square footage if development of these properties was undertaken) at March 31, 2012:

Factors Which May Influence Future Operations

Our long-term corporate strategy is to continue to focus on acquiring, developing, owning, leasing and managing laboratory and office space for the life science industry. As of March 31, 2012, our current consolidated operating portfolio was 90.7% leased on a weighted-average basis to 177 tenants. As of December 31, 2011, our current consolidated operating portfolio was 90.2% leased on a weighted-average basis to 170 tenants. The increase in the overall leased percentage was due to an increase in leased square feet related to increased leasing activity. Our current operating portfolio increased by approximately 48,600 rentable square feet at March 31, 2012 compared to December 31, 2011, and total leased square footage increased by approximately 319,500 square feet, or 3.2%, during the same period.

Our leasing strategy for 2012 focuses on leasing vacant space, negotiating renewals for leases scheduled to expire during the year, and identifying new tenants or existing tenants seeking additional space to occupy the spaces for which we are unable to negotiate such renewals. We may proceed with additional new developments and acquisitions, as real estate and capital market conditions permit. As of March 31, 2012, leases representing 3.8% and 4.7% of our leased square feet are scheduled to expire during 2012 and 2013, respectively. The success of our leasing and development strategy will be dependent upon the general economic conditions and more specifically real estate market conditions and life science industry trends in the United States and in our target markets. We cannot provide any assurance that leases will be renewed or that available space will be released at rental rates equal to or above the current contractual rental rates or at all.

As a direct result of the recent economic recession, we believe that the fair-values of some of our properties may have declined below their respective carrying values. However, to the extent that a property has a substantial remaining estimated useful life and management does not believe that the property will be disposed of prior to the end of its useful life, it would be unusual for undiscounted cash flows to be insufficient to recover the property's carrying value. During the three months endedMarch 31, 2012, the Company reclassified one property from held and used to held for sale due to the disposition of the property in April 2012 in an exchange with a third party for another operating property. As the carrying value of the property disposed of was less than the consideration received in exchange an impairment loss was recorded. Other than the property held for sale, we presently have the ability and intent to continue to own and operate our existing portfolio of properties and estimated undiscounted future cash flows from the operation of the properties are expected to be sufficient to recover the carrying value of each property. Accordingly, we do not believe that the carrying value of any of our other properties is impaired. If our ability and/or our intent with regard to the operation of our properties otherwise dictate an earlier sale date, an additional impairment loss may be recognized to reduce the property to fair-value and such loss could be material.

A discussion of additional factors which may influence future operations can be found below under Part II, Item 1A, “Risk Factors” and in our annual report on Form 10-K for the year ended December 31, 2011.

Leased square feet as of March 31, 2012	10,395,328

____________

(1) Current annualized base rent per leased square foot is the monthly contractual rent per leased square foot as of the current period ended, or if rent has not yet commenced, the first monthly rent payment per leased square foot due at each rent commencement date, multiplied by 12 months.

(2) Current annualized base rent per leased square foot - GAAP basis is the monthly contractual rent per square foot as of the current period ended, or if rent has not yet commenced, the first monthly rent payment per square foot due at each rent commencement date, multiplied by 12 months as adjusted for straight line rent, fair-value lease revenue, and lease incentive revenue.

(3) Includes the Forbes Boulevard property which was considered held for sale at March 31, 2012 and sold subsequent to quarter end.

(4) Leases on space which, in management's evaluation, require significant improvements to prepare or condition the premises for its intended purpose or enhance the value of the property. This generally includes capital expenditures for development, redevelopment or repositioning a property.

(5) Leases which are not considered by management to be first generation leases.

The following table summarizes our leasing activity and associated leasing costs for the three months ended March 31, 2012:

	Number of leases	Square feet	Tenant improvement costs per square foot		Lease commission costs per square foot		Tenant concession costs per square foot (1)
Renewals, amendments, and extensions (2)	6	70,894	$	10.31	$	2.99	$	7.99

(2) Excludes costs associated with speculative leasing.

(3) Our estimate of the time in which redevelopment will be substantially complete. We estimate that the projects will be substantially complete and held available for their intended use upon the completion of tenant improvements, but no later than one year from the cessation of major construction activities.

The following summarizes our cash spent on capital expenditures (dollars in thousands):

	Three Months Ended March 31,							Percent
	2012		2011		Change			Change
Development	$	443	$	15,449	$	(15,006	)	(97.1	)%

Total capital expenditures	$	42,070	$	41,898	$	172		0.4	%

___________

(1) Recurring capital expenditures exclude (a) capital improvements that were taken into consideration when underwriting the purchase of a building, (b) items associated with the expansion of a building or its improvements, (c) renovations to a building which change the underlying classification of the building, incurred to prepare or condition the premises for its intended purpose (for example, from office to laboratory) or (d) capital improvements that represent an addition to the property rather than the replacement of property, plant, or equipment. Includes revenue enhancing and non-revenue enhancing recurring capital expenditures.

Total capital expenditures increased $172,000 to $42.1 million for the three months endedMarch 31, 2012 from $41.9 million for the three months endedMarch 31, 2011. The change was primarily the result of the three new redevelopment projects described above and increased tenant improvement requirements related to increased leasing activity, partially offset by the placement into service of a development property that was under development in 2011 totaling 176,000 square feet. See discussion in Liquidity and Capital Resources of BioMed Realty, L.P. for further information on obligations for capital expenditures expected to be incurred in the future.

revenue.

(2) Adjustments to cash basis exclude adjustments to expenses accrued in rental operations, but include straight line rents, fair-value lease revenue, lease incentive revenue, bad debt expense and other revenue (including lease termination revenue).

The following table provides a reconciliation of net operating income - cash basis to net income for the three months ended March 31, 2012 and 2011 (dollars in thousands):

Net income	$	2,282		$	9,878		$	(7,596	)	(76.9	)%

Net Operating Income. Net operating income increased $9.2 million to $83.3 million for the three months endedMarch 31, 2012 compared to $74.1 million for the three months endedMarch 31, 2011. This increase was due to the following:

• The acquisition of properties totaling 708,185 square feet in 2011 and properties totaling 286,878 square feet in 2012 contributed an additional $6.5 million in net operating income for the three months endedMarch 31, 2012 compared to the three months endedMarch 31, 2011.

• The placement into service of a development property that was under development in 2011 totaling 176,000 square feet resulted in an increase of $1.6 million in net operating income for the three months endedMarch 31, 2012 compared to the three months endedMarch 31, 2011.

• Same property net operating income increased $1.6 million to $76.3 million for the three months endedMarch 31, 2012 compared to $74.7 million for the three months endedMarch 31, 2011. This increase was primarily due to increased leasing activity in our same property portfolio during 2011 and 2012, which increased the leased percentage from 81.6% at March 31, 2011 to 86.3% at March 31, 2012, and resulted in the following:

• An increase in the percentage of recoverable expenses in our same property portfolio to 84.9% for the three months endedMarch 31, 2012 compared to 81.3% for the three months endedMarch 31, 2011. This increase in the percentage of recoverable expenses contributed an additional $1.1 million in net operating income for the three months endedMarch 31, 2012.

• An increase in rental revenue of $1.2 million directly attributable to the commencement of leases in our same property portfolio. On a GAAP basis, the current annualized base rent per square foot decreased to $37.72 at March 31, 2012 from $38.70 at March 31, 2011 due to lease up of previously vacant space at a lower average rent than our total overall portfolio on a per square foot basis.

• These increases were partially offset by a decrease of $685,000 in other revenue which related to lease termination payments received during the three months endedMarch 31, 2011. On an ongoing basis, we evaluate the credit quality of our tenants. Factors we consider as part of this evaluation include, among other things, the financial strength of the tenant and any guarantors, a review of publicly filed documents and analyst research reports (as a majority of

16

our tenants are public companies), a review of the tenant's cash balance and estimated cash “burn” rate if the tenant's cash flow from operations is negative, and the tenant's payment history.During the three months endedMarch 31, 2012, based on managements review, there have been no changes in tenant credit quality that have had or are expected to have a material impact on our consolidated financial statements.

Depreciation and Amortization Expense. Depreciation and amortization expense increased $11.2 million to $44.9 million for the three months endedMarch 31, 2012 compared to $33.7 million for the three months endedMarch 31, 2011. The increase was primarily due to the acquisition of properties totaling 708,185 square feet with an acquisition date fair value of $431.5 million in 2011 and properties totaling 286,878 square feet with an acquisition date fair value of $119.0 million in 2012.

General and Administrative Expenses. General and administrative expenses increased $1.2 million to $8.6 million for the three months endedMarch 31, 2012 compared to $7.4 million for the three months endedMarch 31, 2011. The increase was primarily due to an increase in aggregate compensation costs due to higher headcount as compared to the prior year.

Acquisition Related Expenses. Acquisition related expenses increased to $633,000 for the three months endedMarch 31, 2012 compared to $320,000 for the three months endedMarch 31, 2011. The increase was primarily due to an increase in acquisition activities in the three months endedMarch 31, 2012 as compared to the prior year period.

Equity in Net Loss of Unconsolidated Partnerships. Equity in net loss of unconsolidated partnerships decreased $293,000 to $355,000 for the three months endedMarch 31, 2012 compared to $648,000 for the three months endedMarch 31, 2011. The decreased loss primarily reflects our acquisition of PREI's interest in certain assets held by PREI I LLC in December 2011. Up to the date of the acquisition, our interest in the related assets was accounted for using the equity method of accounting. Since our acquisition of PREI's interest in December 2011, the related assets have been wholly-owned by us and consolidated within our financial statements.

Interest Expense, Net. Interest cost incurred for the three months endedMarch 31, 2012 totaled $24.6 million compared to $22.7 million for the three months endedMarch 31, 2011. Total interest cost incurred increased primarily as a result of higher average debt balances outstanding during 2012 and increases in the average interest rate on our outstanding borrowings due to the issuance of new fixed-rate indebtedness with a higher interest rate than the variable-rate indebtedness it replaced, partially offset by the expiration of derivative instruments and repayment of certain higher coupon mortgage notes payable. Interest expense, net increased$1.0 million to $22.2 million for the three months endedMarch 31, 2012 compared to $21.2 million for the three months endedMarch 31, 2011. Interest expense, net increased primarily as a result of the increase in interest cost incurred partially offset by an increase in capitalized interest.

Loss on derivative instruments	(8		)	(1,011		)
Total other income / (expense)	$	174		$	(1,054	)

During the three months endedMarch 31, 2012, we repaid in full the outstanding mortgage note totaling approximately $26.2 million pertaining to the Sidney Street property. This resulted in the recognition of a gain on extinguishment of debt representing the write-off of unamortized debt premium, partially offset by the write-off of deferred loan fees. During the three months endedMarch 31, 2011, we repaid in full the outstanding mortgage notes totaling approximately $25.5 million pertaining to the Road to the Cure and the 10255 Science Center Drive properties, prior to their maturity date. The repayments resulted in the recognition of a loss on extinguishment of debt (representing a prepayment penalty and the write-off of deferred loan fees partially offset by the write off of unamortized debt premium). The loss on derivative instruments in 2012 relates to decreases in the value of warrants held, and the loss on derivative instruments in 2011 reflects hedging ineffectiveness associated with certain interest rate derivative contracts.

(Loss) / Income from Discontinued Operations. During the three months endedMarch 31, 2012, a property was reclassified as held for sale and an impairment loss was recorded as the carrying value of the property exceeded the value of the consideration received when the property was disposed of in April 2012.

Cash Flows

Comparison of the Three Months EndedMarch 31, 2012 to the Three Months EndedMarch 31, 2011

Net cash provided by operating activities increased$23.2 million to $64.6 million for the three months endedMarch 31, 2012 compared to $41.4 million for the three months endedMarch 31, 2011. The increase was primarily due to cash flow generated by acquisitions and cash rent starts on new leases.

Net cash used in investing activities increased$116.4 million to $159.2 million for the three months endedMarch 31, 2012 compared to $42.8 million for the three months endedDecember 31, 2011. The increase reflects increased acquisition activity during the three months endedMarch 31, 2012 compared to the three months endedMarch 31, 2011.

Net cash provided by financing activities increased$92.3 million to $91.5 million for the three months endedMarch 31, 2012 compared to a cash outflow of $747,000 for the three months endedMarch 31, 2011. The increase primarily reflects increased financing requirements due to increased acquisition activity during the three months endedMarch 31, 2012 compared to the three months endedMarch 31, 2011. The proceeds from the issuance of our Term Loan in March 2012 were primarily used to repay balances due under our unsecured line of credit and mortgage notes payable. The proceeds from the issuances of our Notes due 2016 in March 2011 were primarily used to repay balances due under our unsecured line of credit and mortgage notes payable.

Funds from Operations

We present funds from operations, or FFO, available to common shares and OP units because we consider it an important supplemental measure of our operating performance and believe it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs, many of which present FFO when reporting their results. FFO is intended to exclude GAAP historical cost depreciation and amortization of real estate and related assets, which assumes that the value of real estate assets diminishes ratably over time. Historically, however, real estate values have risen or fallen with market conditions. Because FFO excludes depreciation and amortization unique to real estate, gains and losses from property dispositions and extraordinary items, it provides a performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, development activities and interest costs, providing perspective not immediately apparent from net income. We compute FFO in accordance with standards established by the Board of Governors of the National Association of Real Estate Investment Trusts, or NAREIT. As defined by NAREIT, FFO represents net income (computed in

18

accordance with GAAP), excluding gains (or losses) from sales of property, impairment charges on depreciable real estate, real estate related depreciation and amortization (excluding amortization of loan origination costs) and after adjustments for unconsolidated partnerships and joint ventures. Our computation may differ from the methodology for calculating FFO utilized by other equity REITs and, accordingly, may not be comparable to such other REITs. Further, FFO does not represent amounts available for management's discretionary use because of needed capital replacement or expansion, debt service obligations, or other commitments and uncertainties. FFO should not be considered as an alternative to net income (loss) (computed in accordance with GAAP) as an indicator of our financial performance or to cash flow from operating activities (computed in accordance with GAAP) as an indicator of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to pay dividends or make distributions.

Our FFO available to common shares and OP units and a reconciliation to net income for the three months endedMarch 31, 2012 and 2011 (in thousands, except per share and share data) was as follows:

(1) Net income allocable to noncontrolling interests in the operating partnership is included in net income available to unitholders of the operating partnership as reflected in the consolidated financial statements of BioMed Realty, L.P., included elsewhere herein.

(2) Reflects interest expense adjustment of the Notes due 2030 based on the “if converted” method. The three months ended March 31, 2012 and 2011 include 10,127,232 and 9,914,076 shares of common stock potentially issuable pursuant to the exchange feature of the Notes due 2030 based on the “if converted” method, respectively. The three months ended March 31, 2012 and 2011 include 1,483,706 and 1,488,424 shares of unvested restricted stock, which are considered anti-dilutive for purposes of calculating diluted earnings per share, respectively.

Liquidity and Capital Resources of BioMed Realty Trust, Inc.

In this “Liquidity and Capital Resources of BioMed Realty Trust, Inc.” section, the term the “Company” refers only to BioMed Realty Trust, Inc. on an unconsolidated basis, and excludes the operating partnership and all other subsidiaries. For further discussion of the liquidity and capital resources of the Company on a consolidated basis, see the section entitled “Liquidity and Capital Resources of BioMed Realty, L.P.” below.

The Company's business is operated primarily through the operating partnership. The Company issues public equity from time to time, but does not otherwise generate any capital itself or conduct any business itself, other than incurring certain expenses in operating as a public company which are fully reimbursed by the operating partnership. The Company itself does not hold any indebtedness, and its only material asset is its ownership of partnership interests of the operating partnership. The Company's principal funding requirement is the payment of dividends on its common and preferred shares. The Company's principal source of funding for its dividend payments is distributions it receives from the operating partnership.

19

As of March 31, 2012, the Company owned an approximate 98.1% partnership interest and other limited partners, including some of our directors, executive officers and their affiliates, owned the remaining 1.9% partnership interest (including LTIP units) in the operating partnership. As the sole general partner of the operating partnership, BioMed Realty Trust, Inc. has the full, exclusive and complete responsibility for the operating partnership's day-to-day management and control.

The liquidity of the Company is dependent on the operating partnership's ability to make sufficient distributions to the Company. The primary cash requirement of the Company is its payment of dividends to its stockholders. The Company also guarantees some of the operating partnership's debt, as discussed further in Note 5 of the Notes to Consolidated Financial Statements included elsewhere herein. If the operating partnership fails to fulfill certain of its debt requirements, which trigger the Company's guarantee obligations, then the Company will be required to fulfill its cash payment commitments under such guarantees. However, the Company's only significant asset is its investment in the operating partnership.

We believe the operating partnership's sources of working capital, specifically its cash flow from operations, and borrowings available under its unsecured line of credit, are adequate for it to make its distribution payments to the Company and, in turn, for the Company to make its dividend payments to its stockholders. However, we cannot assure you that the operating partnership's sources of capital will continue to be available at all or in amounts sufficient to meet its needs, including its ability to make distribution payments to the Company. The unavailability of capital could adversely affect the operating partnership's ability to pay its distributions to the Company, which would in turn, adversely affect the Company's ability to pay cash dividends to its stockholders.

Our short-term liquidity requirements consist primarily of funds to pay for future dividends expected to be paid to the Company's stockholders, operating expenses and other expenditures directly associated with our properties, interest expense and scheduled principal payments on outstanding indebtedness, general and administrative expenses, construction projects, capital expenditures, tenant improvements and leasing commissions.

The Company may from time to time seek to repurchase or redeem the operating partnership's outstanding debt, the Company's shares of common stock or preferred stock or other securities in open market purchases, privately negotiated transactions or otherwise. Such repurchases or redemptions, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

For the Company to maintain its qualification as a REIT, it must pay dividends to its stockholders aggregating annually at least 90% of its ordinary taxable income. While historically the Company has satisfied this distribution requirement by making cash distributions to its stockholders, it may choose to satisfy this requirement by making distributions of cash or other property, including, in limited circumstances, the Company's own stock. As a result of this distribution requirement, the operating partnership cannot rely on retained earnings to fund its ongoing operations to the same extent that other companies whose parent companies are not REITs can. The Company may need to continue to raise capital in the equity markets to fund the operating partnership's working capital needs, acquisitions and developments.

The Company is a well-known seasoned issuer with an effective shelf registration statement which was amended in November 2010 that allows the Company to register an unspecified amount of various classes of equity securities and the operating partnership to register an unspecified amount of various classes of debt securities. As circumstances warrant, the Company may issue equity from time to time on an opportunistic basis, dependent upon market conditions and available pricing. When the Company receives proceeds from preferred or common equity issuances, it is required by the operating partnership's partnership agreement to contribute the proceeds from its equity issuances to the operating partnership in exchange for preferred or partnership units of the operating partnership. The operating partnership may use the proceeds to repay debt, including borrowings under its unsecured line of credit, develop new or existing properties, acquire properties, or for general corporate purposes.

Liquidity and Capital Resources of BioMed Realty, L.P.

In this “Liquidity and Capital Resources of BioMed Realty, L.P.” section, the terms “we,” “our” and “us” refer to the operating partnership together with its consolidated subsidiaries or our operating partnership and BioMed Realty Trust, Inc. together with their consolidated subsidiaries, as the context requires. BioMed Realty Trust, Inc., or our Parent Company, is our sole general partner and consolidates our results of operations for financial reporting purposes. Because we operate on a consolidated basis with our Parent Company, the section entitled “Liquidity and Capital Resources of BioMed Realty Trust, Inc.” should be read in conjunction with this section to understand our liquidity and capital resources on a consolidated basis.

Our short-term liquidity requirements consist primarily of funds to pay for future dividends expected to be paid to our Parent Company's stockholders, operating expenses and other expenditures directly associated with our properties, interest expense and scheduled principal payments on outstanding indebtedness, general and administrative expenses, construction projects, capital expenditures, tenant improvements and leasing commissions.

The remaining principal payments due for our consolidated and our proportionate share of unconsolidated indebtedness (excluding debt premiums and discounts) as of March 31, 2012 were as follows (in thousands):

Debt maturities through 2013 include a mortgage on our 6828 Nancy Ridge Drive property, with an outstanding balance of $6.3 million, as of March 31, 2012. Debt maturities in 2014 include the mortgage secured by our Center for Life Science | Boston property.

Our $341.3 million mortgage loan, which is secured by our Center for Life Science | Boston property in Boston, Massachusetts, includes a financial covenant relating to a minimum amount of net worth. Management believes that it was in compliance with this covenant as of March 31, 2012.

The terms of the indentures governing the Notes due 2016 and Notes due 2020 require compliance with various financial covenants, including limits on the amount of total leverage and secured debt maintained by us and which require us to maintain minimum levels of debt service coverage. Management believes that it was in compliance with these covenants as of March 31, 2012.

On March 30, 2012, we entered into the Term Loan with KeyBank National Association, as administrative agent, and certain other lenders, providing for borrowings to us of $400.0 million.

The Term Loan and the credit agreement governing our unsecured line of credit include certain restrictions and covenants which require compliance with financial covenants relating to the minimum amounts of net worth, fixed charge coverage, unsecured debt service coverage, overall leverage and unsecured leverage ratios, the maximum amount of secured indebtedness and certain investment limitations. Management believes that it was in compliance with these covenants as of March 31, 2012.

Our long-term liquidity requirements consist primarily of funds to pay for scheduled debt maturities, construction obligations, renovations, expansions, capital commitments and other non-recurring capital expenditures that need to be made periodically, and the costs associated with acquisitions of properties that we pursue. At March 31, 2012, we had entered into construction contracts and lease agreements, with a remaining commitment totaling approximately $99.7 million related to tenant improvements, leasing commissions and construction-related capital expenditures, of which $87.1 million are expected to be paid in 2012, and $12.6 million are expected to be paid in 2013 or thereafter.

We expect to satisfy our short-term liquidity requirements through our existing working capital and cash provided by our operations, long-term secured and unsecured indebtedness, the issuance of additional equity or debt securities and the use of net proceeds from the disposition of non-strategic assets. Our rental revenues, provided by our leases, generally provide cash inflows to meet our debt service obligations, pay general and administrative expenses, and fund regular distributions. We expect to satisfy our long-term liquidity requirements through our existing working capital, cash provided by operations, long-term secured and unsecured indebtedness and the issuance of additional equity or debt securities. We also expect to use funds available under our unsecured line of credit to finance acquisition and development activities and capital expenditures on an interim basis. In addition, we have an investment grade rating, which we believe will provide us with continued access to the unsecured debt markets, providing us with an additional source of long term financing.

BioMed Realty Trust, Inc.'s total capitalization at March 31, 2012 was approximately $5.0 billion and comprised the following:

____________

(1) Amount excludes debt premiums of $2.9 million recorded upon the assumption of the outstanding indebtedness in connection with our purchase of the corresponding properties.

(2) Amount excludes a debt discount of $2.1 million.

(3) Amount excludes a debt discount of $2.2 million.

(4) Aggregate amount based on the market closing price of the common stock of our Parent Company of $18.98 per share on the last trading day of the quarter (March 30, 2012). Limited partners who have been issued OP units have the right to require the operating partnership to redeem part or all of their OP units, which right with respect to LTIP units is subject to vesting and the satisfaction of other conditions. We may elect to acquire those OP units in exchange for shares of our Parent Company's common stock on a one-for-one basis, subject to adjustment. At March 31, 2012, 154,163,339 of the outstanding OP units had been issued to our Parent Company upon receipt of the net proceeds from the issuance of an equal number of shares of our Parent Company's common stock.

(5) Based on the liquidation preference of $25.00 per share of our Parent Company's 7.375% Series A preferred stock (we have issued a corresponding number of 7.375% Series A preferred units).

Although our organizational documents do not limit the amount of indebtedness that we may incur, our Parent Company's board of directors has adopted a policy of targeting our indebtedness at approximately 50% of our total asset book value. At March 31, 2012, the ratio of debt to total asset book value was approximately 39.9%. However, our Parent Company's board of directors may from time to time modify our debt policy in light of current economic or market conditions including, but not limited to, the relative costs of debt and equity capital, market conditions for debt and equity securities and fluctuations in the market price of our Parent Company's common stock. Accordingly, we may increase or decrease our debt to total asset book value ratio beyond the limit described above. In addition, the terms of the indentures governing our Notes due 2016 and Notes due 2020, the Term Loan credit facility and the credit agreement governing our unsecured line of credit require compliance with various financial covenants and ratios, which are discussed in detail above and in Note 5 in the Notes to Consolidated Financial Statements contained elsewhere herein.

We may from time to time seek to repurchase or redeem our outstanding debt, OP units or preferred units (subject to the repurchase or redemption of an equivalent number of shares of common stock or preferred stock by our Parent Company) or other securities, and our Parent Company may seek to repurchase or redeem its outstanding shares of common stock or preferred stock or other securities, in each case in open market purchases, privately negotiated transactions or otherwise. Such repurchases or redemptions, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors.

Off-Balance Sheet Arrangements

As of March 31, 2012, we had investments in the following unconsolidated partnerships: (1) McKellar Court limited partnership, which owns a single tenant occupied property located in San Diego; and (2) two limited liability companies with PREI, which own a portfolio of properties located in Cambridge, Massachusetts (see Note 8 of the Notes to Consolidated Financial Statements included elsewhere herein for more information).

The McKellar Court partnership is a VIE; however, we are not the primary beneficiary. The limited partner at McKellar Court is the only tenant in the property and will bear a disproportionate amount of any losses. We, as the general partner, will receive 22% of the operating cash flows and 75% of the gains upon sale of the property. We account for our general partner interest using the equity method. The assets of the McKellar Court partnership were $14.3 million and $14.4 million and the liabilities were $10.5 million and $10.5 million at March 31, 2012 and December 31, 2011, respectively. Our equity in net income of the McKellar Court partnership was $227,000 and $225,000 for the three months ended March 31, 2012 and 2011, respectively. In December 2009, we provided funding in the form of a promissory note to the McKellar Court partnership in the amount of $10.3 million, which matures at the earlier of (1) January 1, 2020, or (2) the day that the limited partner exercises an option to purchase our ownership interest. Interest-only payments on the promissory note are due monthly at a fixed rate of 8.15% (the rate may adjust higher after January 1, 2015), with the principal balance outstanding due at maturity.

PREI II LLC is a VIE; however, we are not the primary beneficiary. PREI will bear the majority of any losses incurred. PREI I LLC does not qualify as a VIE. In addition, consolidation is not required as we do not control the limited liability companies. In connection with the formation of the PREI joint ventures in April 2007, we contributed 20% of the initial capital. However, the amount of cash flow distributions that we receive may be more or less based on the nature of the circumstances underlying the cash distributions due to provisions in the operating agreements governing the distribution of funds to each member and the occurrence of extraordinary cash flow events. We account for our member interests using the equity method for both limited liability companies. The assets of the PREI joint ventures were $248.3 million and $249.7 million at March 31, 2012 and December 31, 2011, respectively, and the liabilities were $141.0 million and $140.2 million at March 31, 2012 and December 31, 2011, respectively. Our equity in net loss of the PREI joint ventures was $581,000 and $873,000 for the three months endedMarch 31, 2012 and 2011, respectively.

We are the primary beneficiary in six other VIEs, consisting of single-tenant properties in which the tenant has a fixed-price purchase option, which are consolidated and reflected in our consolidated financial statements.

Our proportionate share of outstanding debt related to our unconsolidated partnerships is summarized below (dollars in thousands):

					Principal Amount(1)
Name	Ownership Percentage		Interest Rate(2)		March 31, 2012		December 31, 2011		Maturity Date
PREI I LLC(3)	20	%	3.3	%	$	27,795	$	27,795	August 13, 2013
Total					$	27,795	$	27,795

____________

(1) Amount represents our proportionate share of the total outstanding indebtedness for each of the unconsolidated partnerships.

(2) Effective or weighted-average interest rate of the outstanding indebtedness as of March 31, 2012.

(3) Amount represents our proportionate share of a secured loan, which bears interest at a LIBOR-indexed variable rate with a borrowing capacity of up to $139.0 million. The secured loan was executed by a wholly owned subsidiary of PREI I LLC in connection with the construction of the 650 East Kendall Street property. In accordance with the loan agreement, Prudential Insurance Corporation of America has guaranteed repayment of the secured loan.

Cash Distribution Policy

We elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, or the Code, commencing with our taxable year ended December 31, 2004. To qualify as a REIT, we must meet a number of organizational and operational requirements, including the requirement that we distribute currently at least 90% of our ordinary taxable income to our stockholders. It is our intention to comply with these requirements and maintain our REIT status. As a REIT, we generally will not be subject to corporate

23

federal, state or local income taxes on taxable income we distribute currently (in accordance with the Code and applicable regulations) to our stockholders. If we fail to qualify as a REIT in any taxable year, we will be subject to federal, state and local income taxes at regular corporate rates and may not be able to qualify as a REIT for subsequent tax years. Even if we qualify as a REIT for federal income tax purposes, we may be subject to certain state and local taxes on our income and to federal income and excise taxes on our undistributed taxable income, i.e., taxable income not distributed in the amounts and in the time frames prescribed by the Code and applicable regulations thereunder.

While we most recently paid a dividend on shares of common stock at an annual dividend rate of $0.86 per share, the actual dividend payable in the future will be determined by our board of directors based upon the circumstances at the time of declaration and, as a result, the actual dividend payable in the future may vary from the current rate. The decision to declare and pay dividends on shares of our common stock in the future, as well as the timing, amount and composition of any such future dividends, will be at the sole discretion of our board of directors in light of conditions then existing, including our earnings, financial condition, capital requirements, debt maturities, the availability of debt and equity capital, applicable REIT and legal restrictions and the general overall economic conditions and other factors.

The following table provides historical dividend information for our common and preferred stock for the prior two fiscal years and the three months endedMarch 31, 2012:

Quarter Ended	Date Declared	Date Paid	Dividend per Common Share		Dividend per Preferred Share
March 31, 2010	March 15, 2010	April 15, 2010	$	0.140	$	0.46094

March 31, 2012	March 15, 2012	April 16, 2012	0.215		0.46094

Inflation

Some of our leases contain provisions designed to mitigate the adverse impact of inflation. These provisions generally increase rental rates during the terms of the leases either at fixed rates or indexed escalations (based on the Consumer Price Index or other measures). We may be adversely impacted by inflation on the leases that do not contain indexed escalation provisions. In addition, most of our leases require the tenant to pay an allocable share of operating expenses, including common area maintenance costs, real estate taxes and insurance. This may reduce our exposure to increases in costs and operating expenses resulting from inflation, assuming our properties remain leased and tenants fulfill their obligations to reimburse us for such expenses.

Portions of our unsecured line of credit bear interest at a variable rate, which will be influenced by changes in short-term interest rates, and will be sensitive to inflation.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our future income, cash flows and fair-values relevant to financial instruments depend upon prevailing market interest rates. Market risk is the exposure to loss resulting from changes in interest rates, foreign currency exchange rates, commodity prices and equity prices. The primary market risk to which we believe we are exposed is interest rate risk. Many factors, including governmental monetary and tax policies, domestic and international economic and political considerations and other factors that are beyond our control contribute to interest rate risk.

As of March 31, 2012, our consolidated debt consisted of the following (dollars in thousands):

24

					Effective Interest
			Percent of		Rate at
	Principal Balance (1)		Total Debt		March 31, 2012
Fixed interest rate (2)	$	1,384,860	76.5	%	5.58	%
Variable interest rate (3)	426,000		23.5	%	1.88	%
Total/weighted-average effective interest rate	$	1,810,860	100.0	%	4.71	%

(1) Principal balance includes only consolidated indebtedness.

(2) Includes five mortgage notes payable secured by certain of our properties (including $2.9 million of unamortized premium), our Notes due 2030, our Notes due 2016 (including $2.1 million of unamortized debt discount), and our Notes due 2020 (including $2.2 million of unamortized debt discount).

(3) Includes our Term Loan and our unsecured line of credit, which bear interest at a LIBOR-indexed variable interest rate, plus a credit spread. The stated effective rate for the variable interest debt excludes the impact of any interest rate swap agreements. We have entered into four interest rate swaps, which are intended to have the effect of initially fixing the interest rate on $200.0 million of the outstanding amount under our Term Loan at a weighted-average interest rate of approximately 2.81% (including applicable credit spreads for the underlying debt), subject to adjustment based on our credit ratings.

To determine the fair-value of our outstanding consolidated indebtedness, we utilize quoted market prices to estimate the fair-value, when available. If quoted market prices are not available, we calculate the fair-value of our mortgage notes payable and other fixed-rate debt based on an estimate of current lending rates, assuming the debt is outstanding through maturity and considering the notes’ collateral. In determining the current market rate for fixed-rate debt, a market credit spread is added to the quoted yields on federal government treasury securities with similar terms to debt. In determining the current market rate for variable-rate debt, a market credit spread is added to the current effective interest rate. At March 31, 2012, the fair-value of the fixed-rate debt was estimated to be $1.5 billion compared to the net carrying value of $1.4 billion (includes $2.9 million of unamortized debt premium, $2.1 million of unamortized debt discount associated with the Notes due 2016 and $2.2 million of unamortized debt discount associated with the Notes due 2020). At March 31, 2012, the fair-value of the variable-rate debt was estimated to be equal to the net carrying value of $426.0 million. We do not believe that the interest rate risk represented by our fixed-rate debt or the risk of changes in the credit spread related to our variable-rate debt was material as of March 31, 2012 in relation to total assets of $4.5 billion and equity market capitalization of $3.2 billion of BioMed Realty Trust, Inc.’s common stock and preferred stock, and BioMed Realty, L.P.’s OP units.

Based on the unhedged outstanding balances of our unsecured line of credit, our Term Loan and our proportionate share of the outstanding balance for the PREI joint ventures’ secured construction loan at March 31, 2012, a 1% change in interest rates would change our interest costs by approximately $2.5 million per year. This amount was determined by considering the impact of hypothetical interest rates on our financial instruments. This analysis does not consider the effect of any change in overall economic activity that could occur in that environment. Further, in the event of a change of the magnitude discussed above, we may take actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, this analysis assumes no changes in our financial structure.

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 swaps, caps and treasury locks in order to mitigate our interest rate risk on a related financial instrument. The use of these types of instruments to hedge our exposure to changes in interest rates carries additional risks, including counterparty credit risk, the enforceability of hedging contracts and the risk that unanticipated and significant changes in interest rates will cause a significant loss of basis in the contract. To limit counterparty credit risk we will seek to enter into such agreements with major financial institutions with high credit ratings. There can be no assurance that we will be able to adequately protect against the foregoing risks and will ultimately realize an economic benefit that exceeds the related amounts incurred in connection with engaging in such hedging activities. We do not enter into such contracts for speculative or trading purposes.

ITEM 5. OTHER INFORMATION

On April 27, 2012, we completed the exchange of our Forbes Boulevard property in South San Francisco, California, for the property owned and occupied by a life sciences company located at 550 Broadway Street (the “Broadway Property”) in Redwood City, California, adjacent to the Stanford Medicine Outpatient Center (the “Exchange”).

In connection with the Exchange, the parties to the transaction determined and agreed that the fair value of the consideration exchanged in the transaction was $28.0 million and, as a result, we recognized a non-cash impairment charge of approximately $4.6 million on the Forbes Boulevard property in the first quarter of 2012, which reduced net income for the quarter by the same amount. The non-cash impairment charge had no impact on our funds from operations or adjusted funds from operations results. The non-cash impairment charge represents the excess of the book value of the Forbes Boulevard property plus other transaction costs, over the estimated fair-value of the consideration received in the transaction. We do not anticipate that the impairment charge will result in any material future cash expenditures.
