This Supplemental Operating and Financial Data package contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 based on current expectations, forecasts and assumptions that involve risks and uncertainties that could cause actual outcomes and results to differ materially. These risks and uncertainties include, without limitation: general risks affecting the real estate industry (including, without limitation, the inability to enter into or renew leases, dependence on tenants’ financial condition, and competition from other developers, owners and operators of real estate); adverse economic or real estate developments in the life science industry or the company’s target markets; risks associated with the availability and terms of financing, the use of debt to fund acquisitions, developments and other investments, and the ability to refinance indebtedness as it comes due; failure to maintain the company’s investment grade credit ratings with the ratings agencies; failure to manage effectively the company’s growth and expansion into new markets, or to complete or integrate acquisitions and developments successfully; reductions in asset valuations and related impairment charges; risks and uncertainties affecting property development and construction; risks associated with downturns in foreign, domestic and local economies, changes in interest rates and foreign currency exchange rates, and volatility in the securities markets; ownership of properties outside of the United States that subject the company to different and potentially greater risks than those associated with the company’s domestic operations; risks associated with the company’s investments in loans, including borrower defaults and potential principal losses; potential liability for uninsured losses and environmental contamination; risks associated with the company’s potential failure to qualify as a REIT under the Internal Revenue Code of 1986, as amended, and possible adverse changes in tax and environmental laws; and risks associated with the company’s dependence on key personnel whose continued service is not guaranteed. For a further list and description of such risks and uncertainties, see the reports filed by the company with the Securities and Exchange Commission, including the company’s most recent annual report on Form 10-K and quarterly reports on Form 10-Q. The company disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. All amounts shown in this report are unaudited. This Supplemental Operating and Financial Data package is not an offer to sell or solicitation to buy securities of BioMed Realty Trust, Inc.

NON-GAAP FINANCIAL MEASURE DEFINITIONS
SEPTEMBER 30, 2012
This document includes certain non-GAAP financial measures that management believes are helpful in understanding our business, as further described below. Our definition and calculation of non-GAAP financial measures may differ from those of other REITs, and therefore, may not be comparable. The non-GAAP measures should not be considered an alternative to net income as an indicator of our performance and should be considered only a supplement to cash flows from operating, investing or financing activities as a measure of liquidity, computed in accordance with GAAP.
Funds from Operations (FFO), Core Funds from Operations (CFFO), and Adjusted Funds from Operations (AFFO)
We present funds from operations, or FFO, core funds from operations, or CFFO, and adjusted funds from operations, or AFFO, available to common shares and partnership and LTIP units because we consider them important supplemental measures of our operating performance and believe they are frequently used by securities analysts, investors and other interested parties in the evaluation of REITs, many of which present FFO, CFFO, and AFFO 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 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.
We calculate CFFO by adding acquisition-related expenses to FFO. We calculate AFFO by adding to CFFO: (a) non-cash revenues and expenses, (b) recurring capital expenditures and second generation tenant improvements, and (c) leasing commissions.
Our computation of FFO, CFFO and AFFO may differ from the methodology for calculating FFO, CFFO and AFFO utilized by other equity REITs and, accordingly, may not be comparable to such other REITs. Further, FFO, CFFO and AFFO do 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, CFFO and AFFO 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. FFO, CFFO and AFFO should be considered only as supplements to net income computed in accordance with GAAP as measures of our operations.
Earnings before Interest, Taxes, Depreciation and Amortization (EBITDA) and Adjusted EBITDA
EBITDA is defined as earnings before interest, taxes, depreciation and amortization. We calculate adjusted EBITDA by adding to EBITDA: (a) noncontrolling interests in our operating partnership, (b) impairments, (c) dividends payable on and cost on redemption of our series A preferred stock, (d) non-cash adjustments for marketable securities, (e) gains or losses from sales of real estate, and (f) acquisition-related expenses. Management uses EBITDA and adjusted EBITDA as indicators of our ability to incur and service debt. In addition, we consider EBITDA and adjusted EBITDA to be appropriate supplemental measures of our performance because they eliminate depreciation and interest, which permits investors to view income from operations without the impact of non-cash depreciation or the cost of debt. However, because EBITDA and adjusted EBITDA are calculated before recurring cash charges including interest expense and taxes, and are not adjusted for capital expenditures or other recurring cash requirements of our business, their utility is limited.
Coverage Ratios
We present interest and fixed charge ratios as supplemental liquidity measures. Management uses these ratios as indicators of our financial flexibility to service current interest expense and debt amortization from current cash net operating income. In addition, we believe that these coverage ratios represent common metrics used by securities analysts, investors and other interested parties to evaluate our ability to service fixed cash payments. However, because these ratios are derived from adjusted EBITDA, their utility is limited by the same factors that limit the usefulness of adjusted EBITDA as a liquidity measure.
Net Operating Income (NOI)
We use net operating income, or NOI, as a performance measure and believe NOI provides useful information to investors regarding our financial condition and results of operations because it reflects only those income and expense items that are incurred at the property level. We compute NOI by adding or subtracting certain items from net income, noncontrolling interest in the operating partnership, gains/losses from investment in unconsolidated partnerships, interest expense, interest income, depreciation and amortization, and general and
administrative expenses. NOI presented by us may not be comparable to NOI reported by other REITs that define NOI differently. NOI should not be considered as an alternative to net income as an indication of our performance or to cash flows as a measure of liquidity or ability to make distributions.
