Earnings Per Share
5. Earnings Per Share

Basic earnings per share was calculated by dividing our net income by the weighted average number of common shares outstanding during the period, excluding nonvested restricted stock which is considered to be contingently issuable. To calculate diluted earnings per share, common share equivalents are added to the weighted average number of common shares outstanding. Common share equivalents are computed based on the number of outstanding stock options and unvested restricted stock as calculated using the treasury stock method. However, in periods when the exercise price of our stock options, by grant, is greater than our average stock price during the period, those common share equivalents are considered anti-dilutive and are excluded from the calculation of diluted earnings per share. Options to purchase 25,000 and 15,000 shares were outstanding at March 31, 2012 and March 26, 2011, respectively, but were excluded from the calculation of dilutive earnings per share as their effect would have been anti-dilutive.

The following table sets forth the computation of basic earnings per share and diluted earnings per share:
