Stock-based Compensation

In August 2008, the Company’s stockholders approved the 2008 Long-Term Incentive Plan (the "Incentive Plan"), which replaced the 1992 Stock Option Plan, as amended, and the 1992 Director Stock Option Plan, as amended. As of June 30, 2015, the Incentive Plan is authorized to issue stock options, restricted stock units and performance shares, among other types of awards, for up to 5,199,210 shares of common stock, par value $0.001 per share (the "common stock").

The Company recognized stock-based compensation expense of $2,279 and $2,312 for the three-months ended June 30, 2015 and 2014, respectively. The Company recognized total income tax benefit for stock-based compensation arrangements of $870 and $843 for the three-months ended June 30, 2015 and 2014, respectively. Stock-based compensation expense is recorded in Selling, general & administrative expense within the Company’s Consolidated Statements of Operations.

Stock options

Stock option awards are granted with an exercise price equal to the closing market price of the common stock on the date of grant; such stock options generally become exercisable in equal amounts over a three-year period and have a contractual life of ten-years from the grant date. The fair value of stock options is estimated on the grant date using the Black-Scholes option pricing model, which includes the following weighted-average assumptions.



	Three-months ended
	June 30
	2015		2014
Expected life (in years)	7.5		7.7
Risk free interest rate	2.0	%	2.3	%
Annual forfeiture rate	1.5	%	1.5	%
Expected Volatility	43.9	%	45.1	%
Dividend yield	1.8	%	1.3	%

The following table summarizes the Company’s stock option activity:



	Shares (in 000’s)		Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Life (Years)	Intrinsic Value (000’s)
Outstanding at March 31, 2015	1,844		$	31.65
Granted	160		19.51
Exercised	—		—
Forfeited or cancelled	(85	)	34.19
Outstanding at June 30, 2015	1,919		$	30.52	3.8	$	231
Exercisable at June 30, 2015	1,613		$	32.28	2.7	$	—

The weighted-average grant-date fair value of options granted during the three-months ended June 30, 2015 and 2014 was $7.79 and $9.59, respectively. The intrinsic value of options exercised during the three-months ended June 30, 2015 and 2014 was $0 and $0, respectively. The aggregate intrinsic value in the preceding table is based on the closing stock price of the common stock on June 26, 2015, which was $20.96.

The following table summarizes certain information regarding the Company’s non-vested stock options:



	Shares (in 000’s)		Weighted-Average Grant-Date Fair Value
March 31, 2015	290		$	9.68
Granted	160		7.79
Vested	(135	)	9.62
Forfeited	(9	)	9.74
June 30, 2015	306		$	8.72

As of June 30, 2015, there was $2,400 of total unrecognized pre-tax stock-based compensation expense related to non-vested stock options, which is expected to be recognized over a weighted-average period of 2.2 years.

Restricted stock units

Restricted stock unit awards are subject to a service condition and typically vest in equal amounts over a three-year period from the grant date. The fair value of restricted stock units is determined based on the number of restricted stock units granted and the closing market price of the common stock on the date of grant.

The following table summarizes the Company’s restricted stock unit activity:



	Shares (in 000’s)		Weighted-Average Grant-Date Fair Value
March 31, 2015	262		$	23.34
Granted	170		19.53
Vested	(151	)	22.41
Forfeited	(12	)	22.99
June 30, 2015	269		$	21.47

The total fair value of shares that vested during the three-months ended June 30, 2015 and 2014 was $2,979 and $3,401, respectively.

As of June 30, 2015, there was $4,135 of total unrecognized pre-tax stock-based compensation expense related to non-vested restricted stock units, which is expected to be recognized over a weighted-average period of 2.2 years.

Performance share awards

Performance share awards are subject to one of the performance goals - the Company's Relative Total Shareholder Return ("TSR") Ranking or cumulative Adjusted EBITDA - each over a three-year period. The Company’s Relative TSR Ranking metric is based on the three-year cumulative return to stockholders from the change in stock price and dividends paid between the starting and ending dates. The fair value of performance share awards (subject to cumulative Adjusted EBITDA) is determined based on the number of performance shares granted and the closing market price of the common stock on the date of grant. The fair value of performance share awards (subject to the Company’s Relative TSR Ranking) is estimated on the grant date using the Monte-Carlo simulation valuation method which includes the following weighted-average assumptions.



	Three-months ended
	June 30
	2015		2014
Risk free interest rate	0.9	%	0.8	%
Expected Volatility	39.9	%	44.7	%
Dividend yield	2.0	%	1.3	%

The following table summarizes the Company’s performance share award activity:



	Shares (in 000’s)		Weighted-Average Grant-Date Fair Value
March 31, 2015	275		$	24.69
Granted	106		19.56
Vested	—		—
Forfeited	(90	)	22.79
June 30, 2015	291		$	23.41

The total fair value of shares that vested during the three-months ended June 30, 2015 and 2014 was $0 and $0, respectively.

As of June 30, 2015, there was $2,334 of total unrecognized pre-tax stock-based compensation expense related to non-vested performance share awards, which is expected to be recognized over a weighted-average period of 2.3 years.
