|(1) | For purposes of computing the ratio of earnings to fixed charges, earnings consist of income before income tax plus fixed charges. Fixed charges consist of interest expense and a
portion of operating rental expense that management believes is representative of the interest component of rental expense. For periods in which the ratio of earnings is less than 1.0, the amounts shown as Deficiency represent the additional
earnings that would be necessary to raise the ratio to 1.0. For the Predecessor periods, the ratio of earnings to fixed charges is not meaningful, given the fact that debt was not held by the Predecessor business.
