(2) A supplemental calculation of the ratio of earnings to fixed charges is presented to exclude nonrecurring merger costs and interest rate swap termination costs. During the nine months ended September 30, 1998, we recorded $92.8 million of fees and expenses related to the Merger and to the integration of the combined companies. In April 1998, we recorded $9.8 million related to interest rate swap termination costs. The ratio of earnings to fixed charges is computed by dividing fixed charges into earnings. Earnings is defined as pretax income from continuing operations adjusted by adding fixed charges and excluding interest capitalized during the period. Fixed charges means the total of interest expenses and amortization of financing costs, the estimated interest component of rental expense on operating leases and preferred stock dividends.
