Earnings (Loss) Per Share

As discussed in Note 2, "Emergence from Chapter 11", on the Effective Date, the old common stock awards and warrants then outstanding under the Company’s prior equity compensation plans were extinguished without recovery.

The Company calculates basic earnings (loss) per share by dividing net income (loss) by the weighted average number of

common shares outstanding, excluding restricted shares. The Company calculates diluted earnings (loss) per share by dividing net income (loss) by the weighted average number of common shares outstanding plus the dilutive effect of outstanding share-based awards, including stock options and restricted stock awards. Warrants generally are included in basic and diluted shares outstanding if there is little or no consideration paid upon exercise of the Warrants. Antidilutive instruments are not considered in this calculation. The Company applies the two-class method to calculate earnings per share. Because both classes share the same rights in dividends and earnings, earnings per share (basic and diluted) are the same for both classes.

The following table presents the reconciliation of basic to diluted weighted average common shares (in thousands):
