Earnings Per Share [Abstract]

Loss Per Share

5. Loss Per Share

We present basic and diluted net income (loss) per share on our Condensed Consolidated Statements of Operations.  Basic net income (loss) per share excludes dilution and is computed by dividing net income (loss) by the weighted-average number of common shares outstanding for the period. Diluted net income (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock (common share equivalents) were exercised or converted into common stock, unless the effect would be antidilutive.  For all periods in which we experience a net loss, all shares of common stock issuable upon exercise of outstanding stock appreciation rights and vesting of outstanding restricted stock units have been excluded from the calculation of weighted-average shares because their inclusion would be antidilutive.

The following table sets forth the share effects of stock-based awards excluded from the computations of diluted loss per share (in thousands).
