| NET INCOME PER COMMON SHARE       | NET INCOME PER COMMON SHAREThe Company utilizes the two-class method of calculating basic net income per common share, as holders of the Company’s Series A convertible preferred stock participated in dividends with holders of the Company’s common stock prior to the conversion in 2012 of such convertible preferred stock into common stock. Net losses are not allocated to holders of the Series A convertible preferred stock.The Company computed its basic and diluted net income per common share as follows: 2012 2011 2010Net income$433,840 $275,697 $54,377Less:     Common stock dividends paid to holders of Series A convertible preferred stock(366) (628) (471)Allocation of income to Series A convertible preferred stock(12,179) (15,557) (2,098)Net income available to common stockholders for basic net income per common share421,295 259,512 51,808Add back:     Common stock dividends paid to holders of Series A convertible preferred stock366 628 471Allocation of income to Series A convertible preferred stock12,179 15,557 2,098Net income available to common stockholders for diluted net income per common share$433,840 $275,697 $54,377      Weighted average common shares outstanding for basic net income per common share70,392 67,158 62,744Weighted average impact of dilutive securities1,397 1,576 1,455Weighted average impact of dilutive warrant— — 72Weighted average impact of assumed convertible preferred stock conversion2,087 4,189 3,107Total shares for diluted net income per common share73,876 72,923 67,378      Basic net income per common share$5.98 $3.86 $0.83      Diluted net income per common share$5.87 $3.78 $0.81Potentially dilutive securities excluded from the calculation of diluted net income per common share were as follows: 2012 2011 2010Weighted average potentially dilutive securities305 345 287Contingently issuable shares that have not met the necessary conditions as of the end of a reporting period are not included in the calculation of diluted net income per common share for that period. The Company had contingently issuable awards outstanding that did not meet the performance conditions as of February 3, 2013, January 29, 2012 and January 30, 2011 and, therefore, were excluded from the calculation of diluted net income per common share for each applicable year. The maximum number of potentially dilutive shares that could be issued upon vesting for such awards was 100, 590 and 611 as of February 3, 2013, January 29, 2012 and January 30, 2011, respectively. These amounts were also excluded from the computation of weighted average antidilutive securities. |
