Non-GAAP Financial Measures
This presentation contains certain non-GAAP measures used by management that we believe are helpful in understanding our business, as further discussed in the paragraphs below. We believe investors should review these non-GAAP measures, along with GAAP net income and cash flow from operating activities, investing activities and financing activities, when evaluating an equity REIT’s operating performance. Our definitions and calculations of these non-GAAP financial and operating measures and other terms may differ from the definitions and methodologies used by other REITs and, accordingly, may not be comparable. These non-GAAP financial and operating measures 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 flows from operating activities, determined in accordance with GAAP, as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to make cash distributions.
FUNDS FROM OPERATIONS (FFO). We define FFO as net income, computed in accordance with GAAP, excluding gains or losses from sales of properties, depreciation and amortization related to real estate, impairment charges and adjustments to reflect our share of FFO of unconsolidated joint ventures. Adjustments for unconsolidated joint ventures are calculated to reflect FFO on the same basis. We compute FFO in accordance with our interpretation of standards established by the National Association of Real Estate
Investment Trusts (“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. We receive non-refundable upfront payments from membership upgrade contracts. In accordance with GAAP, the non-refundable upfront payments and related commissions are deferred and amortized over the estimated membership upgrade contract term. Although the NAREIT definition of FFO does not address the treatment of non-refundable upfront 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). We define Normalized FFO as FFO excluding the following non-operating income and expense items: a) gains and losses from early debt extinguishment, including prepayment penalties and defeasance costs, and b) other miscellaneous non-comparable items. 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.
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 gains or losses from sales of properties, depreciation and amortization related to real estate and impairment charges, 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, and other miscellaneous non-comparable items from 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.
25

NON-GAAP FINANCIAL MEASURES CONTINUED
EARNINGS BEFORE INTEREST, ADJUSTED TAX, DEPRECIATION EBITDARE. AND AMORTIZATION FOR REAL ESTATE (EBITDARE) AND WE DEFINE EBITDARE AS NET INCOME OR LOSS EXCLUDING INTEREST INCOME AND EXPENSE, INCOME TAXES, DEPRECIATION AND AMORTIZATION, GAINS OR LOSSES FROM SALES OF PROPERTIES, IMPAIRMENTS CHARGES, AND ADJUSTMENTS TO REFLECT OUR SHARE OF EBITDARE OF UNCONSOLIDATED JOINT VENTURES. WE COMPUTE EBITDARE IN ACCORDANCE WITH OUR INTERPRETATION OF THE STANDARDS ESTABLISHED BY NAREIT, WHICH MAY NOT BE COMPARABLE TO EBITDARE 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. WE RECEIVE NON-REFUNDABLE UPFRONT PAYMENTS FROM MEMBERSHIP UPGRADE CONTRACTS. IN ACCORDANCE WITH GAAP, THE NON-REFUNDABLE UPFRONT PAYMENTS AND RELATED COMMISSIONS ARE DEFERRED AND AMORTIZED OVER THE ESTIMATED CUSTOMER LIFE. ALTHOUGH THE NAREIT DEFINITION OF EBITDARE DOES NOT ADDRESS THE TREATMENT OF NON-REFUNDABLE UPFRONT PAYMENTS, WE BELIEVE THAT IT IS APPROPRIATE TO ADJUST FOR THE IMPACT OF THE DEFERRAL ACTIVITY IN OUR CALCULATION OF EBITDARE. WE DEFINE ADJUSTED EBITDARE AS
EBITDARE EXCLUDING NON-OPERATING INCOME AND EXPENSE ITEMS, SUCH AS GAINS AND LOSSES FROM EARLY DEBT EXTINGUISHMENT, INCLUDING PREPAYMENT PENALTIES AND DEFEASANCE COSTS, AND OTHER MISCELLANEOUS NON-COMPARABLE ITEMS. WE BELIEVE THAT EBITDARE AND ADJUSTED EBITDARE MAY BE USEFUL TO AN INVESTOR IN EVALUATING OUR OPERATING PERFORMANCE AND LIQUIDITY BECAUSE THE MEASURES ARE WIDELY USED TO MEASURE THE OPERATING PERFORMANCE OF AN EQUITY REIT. 26
