The ratios are calculated by dividing earnings by fixed charges. For the purposes of computing the ratio of earnings to fixed charges, earnings consist of pretax income from continuing operations plus fixed charges. Total earnings is computed as pre-tax income (loss) adjusted for interest expense since fixed charges consist only of interest expense.
