(1) We account for our common share investments in Senior Housing Properties Trust, or Senior Housing, and Hospitality Properties Trust, or Hospitality Properties, using the equity method of accounting. During the nine months ended September 30, 2004, we sold 3,148 of our Senior Housing common shares and recognized a gain of $14,805. In addition, we recognized gains of $4,708 and $5,040 during the nine months ended September 30, 2005 and 2004, respectively, as a result of share issuances by Senior Housing and Hospitality Properties at prices above our per share carrying value.

(2) We compute FFO as shown in the calculation above. Our calculation of FFO differs from the National Association of Real Estate Investment Trusts, or NAREIT, definition because we add loss on early extinguishment of debt unless settled in cash. We consider FFO to be an appropriate measure of performance for a REIT, along with net income and cash flow from operating, investing and financing activities. We believe that FFO provides useful information to investors because by excluding the effects of certain historical costs, such as depreciation expense and gains or losses on sales of properties, FFO can facilitate a comparison of current operating performance among REITs. FFO does not represent cash generated by operating activities in accordance with generally accepted accounting principles, or GAAP, and should not be considered an alternative to net income or cash flow from operating activities as a measure of financial performance or liquidity. FFO is one important factor considered by our Board of Trustees in determining the amount of distributions to shareholders. Other important factors include, but are not limited to, requirements to maintain our status as a REIT, limitations in our revolving bank credit facility and public debt covenants, the availability of debt and equity capital to us and our expectations of future capital requirements and operating performance.
