|(1) | For purposes of calculating the ratio of earnings to fixed charges, earnings are defined as (a) income before income taxes, (income) loss from equity investees and
minority interest plus (b) amortization of capitalized interest and (c) fixed charges, minus interest capitalized. Fixed charges consists of interest expensed and capitalized plus the portion of rental expense considered to be
a reasonable approximation of interest plus the amortization of the discount related to unsecured convertible senior term notes. Effective October 1, 2002, we ceased recording goodwill amortization expense as required by SFAS No. 142. The
ratios shown for the years ended September 30, 2001 and 2002, include goodwill amortization expense.
