Non-GAAP Financial Measures

Funds from Operations (“FFO”) is a non-GAAP financial measure. We believe FFO, as defined by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”), is generally an appropriate measure of performance for an equity REIT. While FFO is a relevant and widely used measure of operating performance for equity REITs, it does not represent cash flow from operations or net income as defined by GAAP, and it should not be considered as an alternative to these indicators in evaluating liquidity or operating performance.

We define FFO as net income, computed in accordance with GAAP, excluding gains and actual or estimated losses from sales of properties, plus real estate related depreciation and amortization, impairments, if any, and after adjustments for unconsolidated partnerships and joint ventures. Adjustments for unconsolidated partnerships and joint ventures are calculated to reflect FFO on the same basis. We receive up-front non-refundable payments from the entry of right-to-use contracts. In accordance with GAAP, the up-front non-refundable payments and related commissions are deferred and amortized over the estimated customer life. Although the NAREIT definition of FFO does not address the treatment of non-refundable right-to-use payments, we believe that it is appropriate to adjust for the impact of the deferral activity in our calculation of FFO.

Normalized Funds from Operations (“Normalized FFO”) is a non-GAAP measure. We define Normalized FFO as FFO excluding the following non-operating income and expense items: a) the financial impact of contingent consideration; b) gains and losses from early debt extinguishment, including prepayment penalties and defeasance costs; c) property acquisition and other transaction costs related to mergers and acquisitions; and d) other miscellaneous non-comparable items.

We believe that FFO and Normalized FFO are helpful to investors as supplemental measures of the performance of an equity REIT. We believe that by excluding the effect of depreciation, amortization and actual or estimated gains or losses from sales of real estate, all of which are based on historical costs and which may be of limited relevance in evaluating current performance, FFO can facilitate comparisons of operating performance between periods and among other equity REITs. We further believe that Normalized FFO provides useful information to investors, analysts and our management because it allows them to compare our operating performance to the operating performance of other real estate companies and between periods on a consistent basis without having to account for differences not related to our operations. For example, we believe that excluding the early extinguishment of debt, property acquisition and other transaction costs related to mergers and acquisitions and the change in fair value of our contingent consideration asset from Normalized FFO allows investors, analysts and our management to assess the sustainability of operating performance in future periods because these costs do not affect the future operations of the properties. In some cases, we provide information about identified non-cash components of FFO and Normalized FFO because it allows investors, analysts and our management to assess the impact of those items.

Investors should review FFO and Normalized FFO along with GAAP net income and cash flow from operating activities, investing activities and financing activities, when evaluating an equity REIT’s operating performance. We compute FFO in accordance with our interpretation of standards established by NAREIT, which may not be comparable to FFO reported by other REITs that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently than we do. Normalized FFO presented herein is not necessarily comparable to normalized FFO presented by other real estate companies due to the fact that not all real estate companies use the same methodology for computing this amount. FFO and Normalized FFO do not represent cash generated from operating activities in accordance with GAAP, nor do they represent cash available to pay distributions and should not be considered as an alternative to net income, determined in accordance with GAAP, as an indication of our financial performance, or to cash flow from operating activities, determined in accordance with GAAP, as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to make cash distributions.
