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 reflect the sum of interest expense, the amount amortized for debt financing costs, and an estimate of the amount of interest within the Company’s rental expense. All interest expense for the Company is classified within continuing operations.
