Basic earnings per share excludes the dilutive effects of stock options, unvested restricted stock and unvested restricted share units. Diluted earnings per share includes only the dilutive effects of common stock equivalents such as stock options and unvested restricted stock awards. The Company used income from continuing operations as the control number in determining whether potential common shares were dilutive or anti-dilutive. The same number of potential common shares used in computing the diluted per share amount from continuing operations was also used in computing the diluted per share amounts from discontinued operations even if those amounts were anti-dilutive. Anti-dilutive stock options and restricted stock awards totaling 4,000 and 591,000 for the three months and 39,000 and 833,000 for the nine months ended March 31, 2012 and 2011, respectively, were excluded from our earnings per share calculations.
