Net Income Per Common Share

Note 11. Net Income Per Common Share

The computation of basic net income per common share for all periods presented is derived from the information on the consolidated statements of income, and there are no reconciling items in the numerator used to compute diluted net income per common share. The total shares used in the denominator of the diluted net income per common share calculation includes 3.9 million, 346 thousand and zero potentially dilutive common equivalent shares outstanding for fiscal 2012, 2011 and 2010, respectively, that are not included in basic net income per common share by applying the treasury stock method to the impact of incremental shares issuable assuming conversion of the debentures (see “Note 14. Convertible Debentures and Revolving Credit Facility”). Additionally, the total shares used in the denominator of the diluted net income per common share calculation includes 4.5 million, 3.6 million and 941 thousand potentially dilutive common equivalent shares outstanding for fiscal 2012, 2011 and 2010, respectively, that are not included in basic net income per common share by applying the treasury stock method to the impact of our equity incentive plans.

Outstanding stock options, RSUs and warrants (See “Note 14. Convertible Debentures and Revolving Credit Facility” for more discussion of warrants) to purchase approximately 30.6 million, 32.7 million, and 44.0 million shares, for fiscal 2012, fiscal 2011, and 2010 respectively, under the Company’s stock award plans were excluded from diluted net income per common share, applying the treasury stock method, as their inclusion would have been antidilutive. These options, RSUs and warrants could be dilutive in the future if the Company’s average share price increases and is greater than the combined exercise prices and the unamortized fair values of these options, RSUs and warrants.
