4. Stock-Based Compensation Plans

Employee Stock Purchase Plan

Under the Company’s 1999 Employee Stock Purchase Plan, as amended (the “ESPP”), a total of 1,500,000 shares of the Company’s common stock have been reserved for issuance to eligible employees. Participating employees are permitted to designate up to the lesser of $25,000 or 10% of their annual base compensation for the purchase of common stock under the ESPP. Purchases under the ESPP are made one calendar month after the end of each fiscal quarter. The price for shares of common stock purchased under the ESPP is 85% of the stock’s fair market value on the last business day of the three-month participation period. Shares issued under the ESPP during the three months ended March 31, 2012 and 2011 totaled 12,483 and 11,373, respectively.

Stock-Based Payments

A summary of stock options issued pursuant to the Company’s stock incentive plans is as follows:


	Number of Shares			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (Years)		Aggregate Intrinsic Value of In-the-Money Options
Outstanding as of December 31, 2011		3,490,056		$	23.28
Granted		14,984			39.25
Exercised		(302,224	)		14.55
Forfeited		(24,966	)		21.64
Expired		(1,500	)		10.04

Outstanding as of March 31, 2012		3,176,350		$	24.20		5.26	$	51,042,035

Exercisable as of March 31, 2012		2,052,169		$	23.92		4.55	$	33,553,777

As of March 31, 2012, the Company expects that 94.6% of the options will vest over the vesting period.

The weighted-average grant date fair value of stock options granted during the three months ended March 31, 2012 was $18.51. No options were granted during the three months ended March 31, 2011. The Company issued treasury shares for the exercise of stock options during the three months ended March 31, 2012 and 2011. The total intrinsic value of stock options exercised during the three months ended March 31, 2012 and 2011 was $7.0 million and $2.8 million, respectively.

The fair value of options granted during the three months ended March 31, 2012 was estimated on the date of grant using the Black-Scholes option-pricing model, a pricing model acceptable under U.S. GAAP, with the following weighted-average assumptions:


	Three Months Ended March 31, 2012
Expected life (years)		5.55
Interest rate		1.1	%
Volatility		51.3	%
Dividend yield		—

Expected volatilities are based on the Company’s historical common stock volatility derived from historical stock price data for historical periods commensurate with the options’ expected life. The expected life of options granted represents the period of time that options granted are expected to be outstanding. The expected option life was the average number of years that the Company estimated that the options will be outstanding, based primarily on historical employee option exercise behavior.

The risk-free interest rate is based on the implied yield currently available on United States Treasury zero coupon issues with a term equal to the expected term at the date of grant of the options. The expected dividend yield is zero as the Company has historically paid no dividends and does not anticipate dividends to be paid in the future.

A summary of nonvested long-term incentive program performance share awards (“LTIP performance shares”) outstanding as of March 31, 2012 and changes during the period are as follows:


Nonvested LTIP Performance Shares	Number of Shares at Expected Attainment			Weighted- Average Grant Date Fair Value
Nonvested as of December 31, 2011		931,571		$	23.33

Stock Incentive Plan — S1 Corporation 2003 Stock Incentive Plan, as amended and restated

In relation to the acquisition of S1 Corporation discussed in Note 2, the Company amended the S1 Corporation 2003 Stock Incentive Plan, as previously amended and restated (the “S1 2003 Incentive Plan”). Restricted share awards (“RSAs) were granted to S1 employees by S1 Corporation prior to the acquisition by the Company in accordance with the terms of the Transaction Agreement (“Transaction RSAs”) under the S1 2003 Incentive Plan. These are the only equity awards currently outstanding under the S1 2003 Incentive Plan and no further grants will be made.

Under the terms of the Transaction Agreement with S1, upon the acquisition, the S1 Transaction RSAs were converted to RSAs of the Company’s stock. These awards have requisite service periods of four years and vest in increments of 25% on the anniversary of the original grant date of November 9, 2011. If an employee is terminated without cause within 12 months from the acquisition date, the RSAs 100% vest. Stock is issued without direct cost to the employee. The RSA grants provide for the payment of dividends on the Company’s common stock, if any, to the participant during the requisite service period (vesting period) and the participant has voting rights for each share of common stock. The conversion of the Transaction RSAs was treated as a modification and as such they were valued immediately prior to and after modification. The Company recognizes compensation expense for RSAs on a straight-line basis over the requisite service period. The incremental fair value as measure upon modification will be recognized on a straight-line basis from modification date through the end of the requisite service period.

A summary of nonvested Transaction RSAs issued under the S1 2003 Stock Incentive Plan as of March 31, 2012 and changes during the period are as follows:


Nonvested Transaction Restricted Share Awards	Number of Restricted Share Awards			Weighted-Average Grant Date Fair Value
Nonvested as of December 31, 2011		—		$	—
Transaction RSAs converted upon acquisition of S1		170,205			35.41
Vested		(67,857	)		35.41
Forfeited		(747	)		35.41

Nonvested as of March 31, 2012		101,601		$	35.41

During the three months ended March 31, 2012, 67,857 shares of the Transaction RSAs vested. The Company withheld 27,310 of those shares to pay the employees’ portion of the minimum payroll withholding taxes.

As of March 31, 2012, there were unrecognized compensation costs of $6.3 million related to nonvested stock options, $3.5 million related to the nonvested RSAs, and $11.8 million related to the LTIP performance shares, which the Company expects to recognize over weighted-average periods of 2.1 years, 3.0 years and 2.1 years, respectively.

The Company recorded stock-based compensation expenses for the three months ended March 31, 2012 and 2011 related to stock options, LTIP performance shares, RSAs, and the ESPP of $5.6 million and $2.4 million, respectively, with corresponding tax benefits of $2.0 million and $0.9 million, respectively. Tax benefits in excess of the option’s grant date fair value are classified as financing cash flows. Estimated forfeiture rates, stratified by employee classification, have been included as part of the Company’s calculations of compensation costs. The Company recognizes compensation costs for stock option awards that vest with the passage of time with only service conditions on a straight-line basis over the requisite service period.

Cash received from option exercises for the three months ended March 31, 2012 and 2011 was $4.4 million and $1.8 million, respectively. The actual tax benefit realized for the tax deductions from option exercises totaled $2.5 million and $1.1 million for the three months ended March 31, 2012 and 2011, respectively.
