The ratios of earnings to combined fixed charges and preferred stock dividends were computed by dividing earnings by fixed charges. For the purpose of calculating the ratios, the earnings have been calculated by adding fixed charges to income from continuing operations before adjustment for noncontrolling interests plus distributions from unconsolidated joint ventures, excluding purchase price fair value adjustments, gains and losses on equity investment and the cumulative effect of changes in accounting principles. With respect to SL Green Realty Corp., fixed charges and preferred stock dividends consist of interest expense including the amortization of debt issuance costs, rental expense deemed to represent interest expense and preferred dividends paid on its Series I Preferred Stock.
