*Earnings related to income taxes reflect a $3.0 million and $12.0 million decrease for the
twelve months ended December 31, 1999 and 1998, due to a financial statement reclassification related to Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes. The ratio of earnings to fixed charges, absent this
reclassification equals 2.65 and 2.69 for the twelve months ended December 31, 1999 and 1998.
