EARNINGS PER SHARE

13. EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income by the weighted average number of common shares (including restricted stock and vested but unissued restricted stock units) outstanding during the period. Diluted earnings per share is based on the combined weighted average number of common shares and common share equivalents outstanding, which include, where appropriate, the assumed exercise of employee stock options, unvested restricted stock awards and unvested restricted stock units. In computing diluted earnings per share, we utilize the treasury stock method.
