Treasury Stock — Treasury stock represents shares of common stock repurchased or withheld by the Company and not yet retired. The Company has applied the cost method in recording its treasury shares. Below is a summary of the Company’s treasury stock activity for the three months ended March 31, 2012:

⁽¹⁾  The Company withheld restricted shares as a result of the election by certain employees to satisfy their tax liabilities upon vesting in restricted stock. The Company determined the number of shares to be withheld based upon market values ranging from $21.95 to $22.40 per share.

As of March 31, 2012, the Company had no plans to retire any shares of treasury stock.

As of March 31, 2012, there was no remaining unrecognized compensation expense related to outstanding stock options as all outstanding options fully vested on April 2, 2009.

Restricted Stock – During the three months ended March 31, 2012, the Company granted 618,230 shares of restricted stock to employees of the Company. The fair value of the restricted stock granted was determined based on the market value of the Company’s common stock on the date of grant, which was $21.63 per share. The Company assumed forfeiture rates ranging from 0% to 5% for the restricted stock awards. Certain of the restricted stock granted vests over three years based on continued service and the remaining restricted stock granted vests over four years based on continued service. The recipients of restricted stock are entitled to receive dividends and to vote their respective shares, however the sale and transfer of the restricted shares is prohibited during the restriction period.

Below is a summary of restricted stock activity for the three months ended March 31, 2012:

	Shares of			Weighted Average
	Restricted			Grant Date
	Stock			Fair Value
Outstanding at January 1, 2012		1,384,390		$	16.85
Granted		618,230		$	21.63

The Company receives an income tax deduction upon vesting of the restricted stock awards. The total fair value of shares that vested during the three months ended March 31, 2012 was $7,636. The Company recognized a tax benefit of approximately $1,067 during the three months ended March 31, 2012 related to these vested shares.

The Company recorded compensation expense of $2,534 and $1,315 related to restricted stock awards during the three months ended March 31, 2012 and 2011, respectively. As of March 31, 2012, the remaining unrecognized compensation expense related to restricted stock awards was $24,996 and the weighted average period over which this remaining compensation expense will be recognized is approximately three years.

Restricted Stock Units – During the three months ended March 31, 2012, the Company granted restricted stock units representing 152,955 hypothetical shares of common stock to employees of the Company. The restricted stock units vest based on a combination of financial performance factors and continued service. The financial performance factors are based on an implied equity value concept that determines an internal rate of return (“IRR”) during the three fiscal year period ending December 31, 2014 based on a formula utilizing a multiple of Adjusted EBITDA subject to certain specified adjustments (as defined in the restricted stock unit award agreement). The financial performance factors for the restricted stock units have a threshold, target and maximum level of payment opportunity. If the IRR for the three year period is at least 8.5%, which is the threshold, one-third of the restricted stock units vest. If the IRR for the three year period is at least 10.5%, which is the target, two-thirds of the restricted stock units vest. If the IRR for the three year period is at least 12.5%, which is the maximum, 100% of the restricted stock units vest. Grantees are eligible to receive a ratable portion of the common stock issuable if the IRR is within the targets previously noted. All payouts of restricted stock units that vest will be subject to an additional one year service requirement and will be paid in the form of common stock if the participant continues to provide services through March 2015, which is the fourth anniversary of the grant date. Restricted stock unit award participants are eligible to receive dividend equivalent payments if and at the time the restricted stock unit awards vest.

Below is a table summarizing the potential number of shares that could vest under restricted stock unit awards granted during the three months ended March 31, 2012 at each of the three target levels of financial performance (excluding forfeiture assumptions):

	Number of
	Shares		Value at
	Vesting		Grant
at IRR of at least 8.5%		50,981	$	1,103
at IRR of at least 10.5%		101,974	$	2,206
at IRR of at least 12.5%		152,955	$	3,308

Due to the fact that the IRR for the three year performance period could not be determined at the time of grant, the Company estimated that the most likely outcome is the achievement of the mid-point IRR level. The fair value of the restricted stock unit awards was determined based on the market value of the Company’s common stock on the date of grant, which was $21.63 per share. The Company assumed a forfeiture rate of 5% for the restricted stock unit awards. If during the service period, additional information becomes available to lead the Company to believe a different IRR level will be achieved for the three-year performance period, the Company will reassess the number of units that will vest for the grant and adjust its compensation expense accordingly on a prospective basis over the remaining service period.

There were no forfeitures of restricted stock unit awards during the three months ended March 31, 2012. The Company recorded compensation expense of $781 and $698 related to restricted stock unit awards during the three months ended March 31, 2012 and 2011, respectively.

During the three months ended March 31, 2012, 113,456 restricted stock unit awards vested. Upon vesting, each restricted stock unit was converted into one share of the Company’s common stock. In addition, the Company paid approximately $346 in dividends on the vested restricted stock units, which represented dividends that had accumulated on the awards since they were granted in 2008. The fair value of the restricted stock unit awards that vested during the three months ended March 31, 2012 was approximately $2,541. The Company recognized a tax benefit of approximately $2,863 during the three months ended March 31, 2012 related to these vested awards.

As of March 31, 2012, the remaining unrecognized compensation expense related to the outstanding restricted stock unit awards was $6,153. The weighted average period over which this remaining compensation expense will be recognized is approximately two years. As of March 31, 2012, the Company had restricted stock units outstanding that represented a total of 1,077,269 hypothetical shares of common stock, net of actual cumulative forfeitures of 19,918 units, assuming the maximum IRR of at least 12.5% is achieved for all of the grants.
