Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share are computed using the weighted average number of common shares outstanding during the period. Diluted earnings per share incorporate the incremental shares issuable upon the assumed exercise of stock options and the assumed vesting of RSUs and restricted stock. Certain of our RSUs and stock options were excluded from the calculation of diluted earnings per share because they were antidilutive, but these equity instruments could be dilutive in the future.

The following chart sets forth the computation of earnings per share (in thousands, except per share amounts):
