(3) Stock-Based Compensation

The Company calculates the fair value of stock-based awards granted to employees and directors on the date of grant and recognizes the calculated fair value, net of estimated forfeitures, as compensation expense over the requisite service periods of the related awards. The following table reflects the total stock-based compensation expense amounts included in the Company's Consolidated Statements of Operations for the periods indicated:



	Three Months Ended
	March 31,
	2013		2012
	(In thousands)
Cost of ATM operating revenues	$	205	$	203
Selling, general, and administrative expenses		2,960		2,357
Total stock-based compensation expense	$	3,165	$	2,560

The increase in stock-based compensation expense during the three months ended March 31, 2013 was due to the issuance of additional shares of restricted stock awards ("RSAs") and restricted stock units ("RSUs") to certain of the Company's employees and directors during the last twelve months and additional expense recognition associated with grants of certain awards to employees who have met the qualified retirement provisions of our RSUs. All grants during the periods above were made under the Company's Amended and Restated 2007 Stock Incentive Plan (the "2007 Stock Incentive Plan").

Restricted Stock Awards. The number of the Company's outstanding RSAs as of March 31, 2013, and changes during the three months ended March 31, 2013, are presented below:



	Number of Shares		Weighted Average Grant Date Fair Value
RSAs outstanding as of January 1, 2013		632,107	$	16.36
Granted		73,901	$	26.15
Vested		(210,502)	$	13.60
Forfeited		(10,000)	$	29.57
RSAs outstanding as of March 31, 2013		485,506	$	18.75

As of March 31, 2013, the unrecognized compensation expense associated with all outstanding restricted share grants was approximately $7.1 million, which will be recognized on a straight-line basis over a remaining weighted-average vesting period of approximately 2.2 years.

Restricted Stock Units. In the first quarters of each year since 2011, the Company granted RSUs under its respective year’s Long Term Incentive Plans ("LTIPs"), which are equity programs under the 2007 Plan. The ultimate number of RSUs to be earned and outstanding are approved by the Compensation Committee of the Company's Board of Directors (the "Committee"), and are based on the Company's achievement of certain performance levels during the calendar year of its grant. The majority of these grants have both a performance-based and a service-based vesting schedule (“Performance-RSUs”), and the Company recognizes the related compensation expense based on the estimated performance levels that management believes will ultimately be met. Starting with the grants made in 2013, a portion of the awards have only a service-based vesting schedule (“Time-RSUs”), for which the associated expense is recognized ratably over four years. Performance-RSUs and Time-RSUs are convertible into the Company’s common stock after the passage of the vesting periods, which are 24, 36, and 48 months from January 31 of the grant year, at the rate of 50%, 25%, and 25%, respectively. Performance-RSUs will be earned only if the Company achieves certain performance levels. Although the RSUs are not considered to be earned and outstanding until at least the minimum performance metrics are met, the Company recognizes the related compensation expense over the requisite service period (or to an employee’s qualified retirement date, if earlier) using a graded vesting methodology.

The number of the Company's non-vested RSUs as of March 31, 2013, and changes during the three months ended March 31, 2013, are presented below:



	Number of Units		Weighted Average Grant Date Fair Value
Non-vested RSUs as of January 1, 2013		749,948	$	20.01
Granted		119,744	$	27.10
Vested		(261,000)	$	16.98
Forfeited		(10,567)	$	22.67
Non-vested RSUs as of March 31, 2013		598,125	$	22.70

The above table only includes earned RSUs; therefore, the Performance-RSUs granted in 2013 but not yet earned are not included, but the Time-RSUs are included as granted.

As of March 31, 2013, the unrecognized compensation expense associated with earned RSUs was approximately $7.8 million, which will be recognized using a graded vesting schedule for Performance-RSUs and a straight-line vesting schedule for Time-RSUs, over a remaining weighted-average vesting period of approximately 2.5 years.

Options. The number of the Company's outstanding stock options as of March 31, 2013, and changes during the three months ended March 31, 2013, are presented below:



	Number of Shares		Weighted Average Exercise Price
Options outstanding as of January 1, 2013		552,799	$	9.68
Exercised		(37,935)	$	6.51
Forfeited		(1,875)	$	11.05
Options outstanding as of March 31, 2013		512,989	$	9.91

Options vested and exercisable as of March 31, 2013		487,239	$	10.03

As of March 31, 2013, the unrecognized compensation expense associated with outstanding options was approximately $48,000, which will be recognized on a straight-line basis over a remaining weighted-average vesting period of approximately 0.7 years.
