Earnings Per Share

(18) Earnings per Share

Basic earnings per share is computed by dividing income available to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed in the same manner as basic earnings per share, except that the denominator is increased to include the number of additional shares of common stock that could have been outstanding assuming the exercise of stock options and the conversion of restricted stock units.

Diluted earnings per share for the Successor Period, Successor Quarter, Prior Predecessor Period and Prior Predecessor Quarter do not include any potentially dilutive shares as these periods reflected a net loss.
