| | For the purpose of computing the ratio of earnings to fixed charges, earnings consist of earnings (loss) from continuing operations before income taxes and changes in accounting
principle plus fixed charges. Fixed charges consist of interest expense, amortization of debt issuance cost, and one-third of rent expense, which is deemed to be representative of interest expense.
