Stock Plans [Abstract]
STOCK PLANS	11. STOCK PLANS: In addition to grants of stock options to its directors and employees, the Company’s 2006 Omnibus Incentive Plan (the “Plan”) permits the award of restricted stock and restricted stock units (“Restricted Stock Awards”). The fair value of Restricted Stock Awards is determined based on the market price of the Company’s stock at the date of grant. The Company generally records compensation expense equal to the fair value of each Restricted Stock Award granted over the vesting period. During the six months ended June 30, 2011, the Company granted 186,470 Restricted Stock Awards with time- based vesting and a weighted-average grant-date fair value of $34.02 per award. Additionally, the Company granted 67,400 Restricted Stock Awards to certain members of its management team which may vest in 2014. The number of awards that will ultimately vest will be based on Company performance relative to the annual budgets approved by the Company’s board of directors. The Company will not begin recognizing compensation cost for these awards until the fourth quarter of 2012 when the 2013 budget is approved and the key terms and conditions of the awards will be deemed to be established and a grant date will have occurred. At June 30, 2011 and December 31, 2010, Restricted Stock Awards of 622,050 and 471,894 shares, respectively, were outstanding. The compensation cost that has been charged against pre-tax income for all of the Company’s stock-based compensation plans was $2.5 million and $1.9 million for the three months ended June 30, 2011 and 2010, respectively, and $4.8 million and $3.5 million for the six months ended June 30, 2011 and 2010, respectively.
