Funds From Operations does not represent cash flow from operations as defined by generally accepted accounting principles, should not be considered as an alternative to net income as an indicator of the Company's operating performance, and is not indicative of cash available to fund all cash flow needs. In March 1995, NAREIT issued a clarification of its definition of FFO effective for years beginning after December 31, 1995. The clarification provides that amortization of deferred financing costs and depreciation of non-rental real estate assets are no longer to be added back to net income in arriving at FFO. The Company adopted these changes effective January 1, 1996, and the calculations of FFO for the quarterly periods during the year ended December 31, 1995 have been revised accordingly.
