| 1 | For purposes of calculating the ratio of earnings to fixed charges, earnings are defined as income from continuing operations before income taxes and cumulative effect of change in accounting principles plus fixed charges. Fixed charges include interest expense (including amortization of deferred financing costs) and an estimate of operating rental expense, approximately 20%, which management believes is representative of the interest component. |
