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

	Three and Six Months Ended June 30, 2011
	Shares	Weighted- Average Grant-Date Fair Value
Restricted stock awards	154,214	$	48.43
Performance stock awards	69,948	$	48.13
Total awards	224,162

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 June 30, 2011, based on year-to-date results of operations, management did not believe that it was probable that the performance targets, which must be attained by December 31, 2012, would be achieved and as a result, no expense was recorded during the three and six months ended June 30, 2011 related to the 2011 performance stock awards.
