(a) Fixed charges include the portion of rental expense that management believes is representative of the interest component.

The earnings to fixed charges ratio is calculated by dividing earnings available for fixed charges for each period by fixed charges for that period. Earnings available for fixed charges is calculated by adding pre-tax income from continuing operations and fixed charges. Fixed charges are the sum of interest expense, amortization of premiums, discounts and capitalized expenses related to indebtedness, and an estimated interest component of rental expense (from both continuing and discontinued operations). All interest expense for the Company is classified within continuing operations.
