Net income (loss) per share: |  |  |  |  |  |  |  |  |
Basic |  | $ | (3.62 | ) |  | $ | 1.11 |  |  | $ | 2.62 |
Diluted |  | $ | (3.62 | ) |  | $ | 0.97 |  |  | $ | 2.37 |
Incremental shares from stock options and restricted stock awards are computed by the treasury stock method. The weighted average shares listed below were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the periods presented or were otherwise excluded under the treasury stock method. The treasury stock method calculates dilution assuming the exercise of all in-the-money options and vesting of restricted stock, reduced by the repurchase of shares with the proceeds from the assumed exercises, unrecognized compensation expense for outstanding awards and the estimated tax benefit of the assumed exercises.
