Earnings Per Share [Abstract]

Loss Per Share

6. Loss Per Share

We present basic and diluted net loss per share on our unaudited Condensed Consolidated Statements of Operations.  Basic net loss per share excludes dilution and is computed by dividing net loss by the weighted-average number of shares of common stock outstanding for the period.  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 stock-based awards excluded from the computations of diluted loss per share (in thousands).
