| | (1) | The ratio was calculated by dividing the sum of the fixed charges into the sum of the
earnings and fixed charges. In calculating this ratio, earnings include income before income taxes and before fixed charges. Fixed charges include interest expense and one-third of all rent expense (considered representative of the interest factor).
