8.	STOCK PLANS:

In addition to grants of stock options to its directors and employees, the Company’s Amended and Restated 2006 Omnibus Incentive Plan permits the award of restricted stock and restricted stock units. The fair value of restricted stock and restricted stock units with time-based vesting or performance conditions 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 nine months ended September 30, 2014, the Company granted 0.1 million restricted stock units with a weighted-average grant date fair value of $42.60 per award. At September 30, 2014 and December 31, 2013, 0.6 million restricted stock units were outstanding.

The compensation expense that has been charged against pre-tax income for all of the Company’s stock-based compensation plans was $1.5 million and $1.8 million for the three months ended September 30, 2014 and 2013, respectively, and $4.2 million and $6.4 million for the nine months ended September 30, 2014 and 2013, respectively.
