Restricted Stock Units – During the three months ended March 31, 2013, the Company granted restricted stock units representing 115,107 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, 2015 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 2017, 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, 2013 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%		38,366	$	1,129
at IRR of at least 10.5%		76,741	$	2,259
at IRR of at least 12.5%		115,107	$	3,389

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 $29.44 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, 2013. The Company recorded compensation expense of $862 and $781 related to restricted stock unit awards during the three months ended March 31, 2013 and 2012, respectively.

During the three months ended March 31, 2013, 279,697 restricted stock unit awards vested. Upon vesting, each restricted stock unit was converted into one share of the Company’s common stock.

The weighted average period over which this remaining compensation expense will be recognized is approximately two years. As of March 31, 2013, the Company had restricted stock units outstanding that represented a total of 830,081 hypothetical shares of common stock, assuming the maximum IRR level is achieved for each of the grants.
