 (1) Funds From Operations (“FFO”) is used by industry analysts and investorsas a supplemental operating  performancemeasure of an equity real estate investment trust (“REIT”). FFO is calculatedin accordance with the definition that was adopted by the Board of Governors ofthe National Association of Real Estate Investment Trusts (“NAREIT”). FFO, asdefined by NAREIT, represents net income (loss) determined in accordance withgenerally accepted accounting principles (“GAAP”), excluding extraordinaryitems as defined under GAAP and gains or losses from sales of previouslydepreciated operating real estate assets, plus certain non-cash items such asreal estate asset depreciation and amortization, and after similar adjustmentsfor unconsolidated partnerships and joint ventures.

 

Historical costaccounting for real estate assets in accordance with GAAP implicitly assumesthat the value of real estate assets diminishes predictably over time. Sincereal estate values instead have historically risen or fallen with marketconditions, many industry investors and analysts have considered thepresentation of operating results for real estate companies that use historicalcost accounting to be insufficient by themselves. Thus, NAREIT created FFO as asupplemental measure of REIT operating performance that excludes historicalcost depreciation, among other items, from GAAP net income. Management believesthat the use of FFO, combined with the required primary GAAP presentations, hasimproved the understanding of operating results of REITs among the investingpublic and made comparisons of REIT operating results more meaningful.Management considers FFO to be a useful measure for reviewing comparativeoperating and financial performance (although FFO should be reviewed inconjunction with net income which remains the primary measure of performance)because by excluding gains or losses related to sales of previously depreciatedoperating real estate assets and excluding real estate asset depreciation andamortization, FFO assists in comparing the operating performance of a company’sreal estate between periods or as compared to different companies.
