            For purposes of calculating the ratio of earnings to fixed charges, "earnings" have been computed by adding fixed charges, excluding capitalized interest, to income (loss) from continuing operations including income from minority interests and our share of income (loss) from 50%-owned affiliates which have fixed charges, and including distributed operating income from unconsolidated joint ventures instead of income from unconsolidated joint ventures. There are generally no restrictions on our ability to receive distributions from our joint ventures where no preference in favor of the other owners of the joint venture exists. "Fixed charges" consist of interest costs, whether expensed or capitalized, the interest component of rental expenses and amortization of debt issue costs.

            The computation of ratio of earnings to fixed charges has been restated to comply with FASB Statement No. 144 which requires the operating results of the properties sold in the current year to be reclassified to discontinued operations and requires restatement of previous years' operating results of the properties sold to discontinued operations.
