(1)          FundsFrom Operations (“FFO”) is used by industry analysts and investors as asupplemental operating  performancemeasure of an equity real estate investment trust (“REIT”) like our GeneralPartner. FFO is calculated in accordance with the definition that was adoptedby the Board of Governors of the National Association of Real Estate InvestmentTrusts (“NAREIT”).  NAREIT created FFO asa supplemental measure of REIT operating performance that excludes historicalcost depreciation, among other items, from net income determined in accordance with United States generallyaccepted accounting principles (“GAAP”). FFO is a non-GAAP financial measure developed by NAREIT to compare theoperating performance of REITs.  The mostcomparable GAAP measure is net income (loss). FFO should not be considered as a substitute for net income or any othermeasures derived in accordance with GAAP and may not be comparable to othersimilarly titled measures of other companies.

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 presentationof operating results for real estate companies that use historical costaccounting to be insufficient by themselves. FFO, as defined by NAREIT,represents GAAP net income (loss)), excluding extraordinary items as definedunder GAAP and gains or losses from sales of previously depreciated operatingreal estate assets, plus certain non-cash items such as real estate assetdepreciation and amortization, and after similar adjustments for unconsolidatedpartnerships and joint ventures.

Managementbelieves that the use of FFO, combined with the required primary GAAPpresentations, has improved the understanding of operating results of REITsamong the investing public and made comparisons of REIT operating results moremeaningful. Management considers FFO to be a useful measure for reviewingcomparative operating and financial performance (although FFO should bereviewed 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 provides a useful comparison of theoperating performance of our real estate between periods or as compared todifferent companies.
