(1)  Funds From Operations(“FFO”) is used by industry analysts and investors as a supplementaloperating  performance measure of anequity real estate investment trust (“REIT”). FFO is calculated in accordancewith the definition that was adopted by the Board of Governors of the NationalAssociation of Real Estate Investment Trusts (“NAREIT”). FFO, as defined byNAREIT, represents net income (loss) determined in accordance with accountingprinciples generally accepted in the United States (“GAAP”), excludingextraordinary items as defined under GAAP and gains or losses from sales ofpreviously depreciated operating real estate assets, plus certain non-cashitems such as real estate asset depreciation and amortization, and afteradjustment for unconsolidated partnerships and joint ventures.

 

Historical cost accounting for real estate assets in accordance withGAAP implicitly assumes that the value of real estate assets diminishedpredictably over time. Since real estate values instead have historically risenor fallen with market conditions, many industry investors and analysts haveconsidered the presentation of operating results for real estate companies thatuse historical cost accounting to be insufficient by themselves. Thus, NAREITcreated FFO as a supplemental measure of REIT operating performance thatexcludes historical cost depreciation, among other items, from GAAP net income.Management believes that the use of FFO, combined with the required primaryGAAP presentations, has improved the understanding of operating results ofREITs among the investing public and made comparisons of REIT operating resultsmore meaningful. As a REIT subsidiary, thePartnership’s management considers FFO to be a useful measure forreviewing comparative operating and financial performance (although FFO shouldbe reviewed in conjunction with net income which remains the primary measure ofperformance) because by excluding gains or losses related to sales ofpreviously depreciated operating real estate assets and excluding real estateasset depreciation and amortization, FFO assists in comparing the operatingperformance of a company’s real estate between periods or as compared todifferent companies.
