Net Earnings Per Share [Abstract]

Net Earnings Per Share

11.Net Earnings per Share

Basic net earnings per share is computed by dividing net earnings available for basic common shares by the weighted average common shares outstanding during the period.  Diluted net earnings per share is computed by dividing net earnings available for diluted common shares by the sum of weighted average common shares outstanding and dilutive  potential common shares.  For periods with outstanding participating securities, diluted net earnings per share reflects the more dilutive of the “if‑converted” treasury stock method or the two-class method.  For periods with no outstanding participating securities, diluted net earnings per share is calculated using the “if-converted” treasury stock method.  There were no outstanding participating securities during the three months and six months ended August 31, 2012.

Nonvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and should be included in the computation of net earnings per share pursuant to the two-class method.  Our restricted stock awards are considered participating securities because they contain nonforfeitable rights to dividends and are included in the computation of net earnings per share pursuant to the two-class method.  Nonvested MSUs do not receive nonforfeitable dividend equivalent rights, and therefore, are not considered participating securities.  RSUs are nonparticipating, non-equity instruments, and therefore, are excluded from net earnings per share calculations.

⁽¹⁾As discussed in Note 2, fiscal 2012 reflects the revisions to correct our accounting for sale-leaseback transactions.

Certain weighted-average options to purchase shares of common stock were outstanding and not included in the calculation of diluted net earnings per share because their inclusion would have been antidilutive.  For the three months ended August 31, 2012 and 2011, weighted average options to purchase 4,266,794 shares and 3,255,021 shares of common stock, respectively, were not included.  For the six months ended August 31, 2012 and 2011, weighted-average options to purchase 3,678,076 shares and 2,912,288 shares of common stock, respectively, were not included.
