Non-GAAP Financial Measures
FFO, EBITDA and Hotel EBITDA
The Company considers the non-GAAP measures of FFO (including FFO per share/unit), EBITDA and hotel EBITDA to be key supplemental measures of the Company's performance and should be considered along with, but not as alternatives to, net income or loss as a measure of the Company's operating performance. Historical cost accounting for real estate assets implicitly assumes that the value of real estate assets diminishes predictably over time. Since real estate values instead have historically risen or fallen with market conditions, most real estate industry investors consider FFO, EBITDA and hotel EBITDA to be helpful in evaluating a real estate company's operations.
The White Paper on FFO approved by NAREIT in April 2002, as revised in 2011, defines FFO as net income or loss (computed in accordance with GAAP), excluding gains or losses from sales of properties, impairment write-downs and items classified by GAAP as extraordinary, plus real estate-related depreciation and amortization (excluding amortization of deferred finance costs) and after comparable adjustments for the Company's portion of these items related to unconsolidated entities and joint ventures. The Company computes FFO consistent with 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 the Company.
With respect to FFO, the Company believes that excluding the effect of extraordinary items, real estate-related depreciation and amortization, and the portion of these items related to unconsolidated entities, all of which are based on historical cost accounting and which may be of limited significance in evaluating current performance, can facilitate comparisons of operating performance between periods and between REITs, even though FFO does not represent an amount that accrues directly to common shareholders. However, FFO may not be helpful when comparing the Company to non-REITs.
