(1)          FundsFrom Operations (“FFO”) is used by industry analysts and investors as asupplemental operating performance measure of an equity real estate investmenttrust (“REIT”) like our General Partner. FFO is calculated in accordance withthe definition that was adopted by the Board of Governors of the NationalAssociation of Real Estate Investment Trusts (“NAREIT”).  NAREIT created FFO as a supplemental measureof REIT operating performance that excludes historical cost depreciation, amongother items, from net income determined in accordance with United Statesgenerally accepted accounting principles (“GAAP”).  FFO is a non-GAAP financial measure developedby NAREIT to compare the operating performance of REITs.  The most comparable GAAP measure is netincome (loss).  FFO should not beconsidered as a substitute for net income or any other measures derived inaccordance with GAAP and may not be comparable to other similarly titledmeasures 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 analysts and investors have considered presentationof operating results for real estate companies that use historical costaccounting to be insufficient by themselves. FFO, as defined by NAREIT, representsGAAP net income (loss), excluding extraordinary items as defined under GAAP andgains or losses from sales of previously depreciated real estate assets, pluscertain non-cash items such as real estate asset depreciation and amortization,and after similar adjustments for unconsolidated partnerships and jointventures.

 

Managementbelieves that the use of FFO, combined with the required primary GAAPpresentations, improves the understanding of operating results of REITs amongthe investing public and makes comparisons of REIT operating results moremeaningful. Management believes FFO is 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 real estate assets and excluding real estate assetdepreciation and amortization, FFO provides a useful comparison of theoperating performance of our real estate between periods or as compared todifferent companies.
