The ratios of earnings to combined fixed charges and preferred unit distributions 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 gains or losses from sale of property, purchase price fair value adjustments, gains and losses on equity investment and marketable securities and the cumulative effect of changes in accounting principles. With respect to SL Green Operating Partnership, L.P., fixed charges and preferred unit distributions consist of interest expense including the amortization of debt issuance costs, rental expense deemed to represent interest expense and preferred distributions paid on its 7.625% Series C, its 7.875% Series D and its 6.50% Series I cumulative redeemable preferred units.
