The Company calculates FFO consistent with the NAREIT definition, or net income (computed in accordance with GAAP), excluding gains (or losses) from sales of property and impairment losses on depreciable real estate, plus real estate-related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. Real estate-related depreciation includes amortization of capitalized leasing expenses, tenant allowances or improvements, and excludes amortization of deferred financing costs.The Company calculates CAD by further adjusting FFO to exclude straight-line rent adjustments, stock-based compensation, above or below market rent amortization and non-cash interest income and expense, and to include routine capital expenditures on investments in real property and capitalized interest expense (if any). The Company will also adjust its CAD computations to exclude certain non-cash or unusual items. For example, CAD for the 2012 and 2011 periods have been adjusted to exclude non-recurring gains or losses on investments and any gain or loss on extinguishment of debt. The Company also discloses FFO as adjusted for items that affect comparability, as it believes this measure is a useful proxy for existing portfolio performance and, therefore, provides a meaningful presentation of operating performance. Items that affect comparability currently include gains or losses on the Company’s debt investments which, unlike gains or losses on owned properties, are not excluded from FFO under the NAREIT definition, gain or loss on debt extinguishment, debt modification costs and property acquisition costs. FFO as adjusted for items that affect comparability should not be considered as an alternative to net income or earnings per share determined in accordance with GAAP as an indicator of our operating performance or as an alternative to cash flow as a measure of liquidity. It also differs from the NAREIT’s definition of FFO and may not be comparable to similarly titled measures reported by other companies.
