For this purpose, earnings include income before income taxes and fixed charges. Fixed charges include interest and amortization of debt expenses, and the estimated interest component of rentals. Certain amounts for prior years have been restated to conform to the current presentation. During the six months ended June 30, 1997 and five years ended December 31, 1996, there were no shares of preferred stock outstanding. Accordingly, the ratio of earnings to combined fixed charges and preferred stock dividends for each of the six months and five years is the same as the ratio of earnings to fixed charges.
