STOCK-BASED COMPENSATION

The following table summarizes the total number and type of awards granted during the three- and nine-month periods ended September 30, 2011, as well as the related weighted-average grant-date fair values:

	Three Months Ended			Nine Months Ended
	September 30, 2011			September 30, 2011
	Shares	Weighted Average Grant-Date Fair Value		Shares	Weighted Average Grant-Date Fair Value
Restricted stock awards	26,091	$	54.13	180,305	$	48.45
Performance stock awards	3,551	$	50.87	73,499	$	50.87
Total awards	29,642			253,804

All shares and weighted average grant date fair values included in the above table have been adjusted for the two-for-one stock split discussed in Note 1, “Basis of Presentation.” Certain performance stock awards granted in June 2011 are subject to both achieving predetermined revenue and EBITDA targets for a specified period of time and service conditions.  As of September 30, 2011, based on year-to-date results of operations, management determined that it was probable that the performance targets for the 2011 performance awards will be achieved by December 31, 2011. As a result, the Company recognized cumulative expense through sales, general and administration expenses during the three and nine months ended September 30, 2011 related to the 2011 performance stock awards.
