	Stock-Based Compensation

We recognize compensation expense for stock-based compensation awards issued to employees that are expected to vest. Compensation cost is based on the fair value of awards as of the grant date.

The following table summarizes the pre-tax stock-based compensation expense included in reported net income (in thousands):



	Three months ended June 30,				Six months ended June 30,
	2015		2014		2015		2014
Non-qualified stock options	$	52	$	122	$	114	$	254

Pursuant to our 2011 Stock Incentive Plan (the “2011 Plan”), we may grant awards of non-qualified stock options, incentive stock options, restricted stock, stock units, performance shares, performance units and other incentives payable in cash or in shares of our common stock to officers, employees or members of the Board of Directors. As of June 30, 2015, we had non-qualified stock options and restricted stock units outstanding under these plans as discussed below.

Restricted Stock Units

In addition to stock options, we issue restricted stock units to key employees and members of the Board of Directors based on meeting certain service goals. The stock units vest to the recipients at various dates, up to five years, based on fulfilling service requirements. We recognize the value of the market price of the underlying stock on the date of grant as compensation expense over the requisite service period. Upon vesting, the stock units are settled in shares of our common stock. Summarized share information for our restricted stock units is as follows:



	Six Months Ended June 30, 2015		Weighted average grant date fair value
	(In shares)		(In dollars)
Outstanding and unvested, beginning of period	263,084		$	25.00
Granted	82,120		36.71
Vested	(4,276	)	17.05
Forfeited	(508	)	25.30
Outstanding and unvested, end of period	340,420		$	27.92

On March 30, 2015, the Compensation Committee approved an incentive program providing for the issuance to certain executives of the Company a combination of performance-based and time-based restricted stock units under the 2011 Plan. Under the program, a target level of equity compensation is set for each officer. The total equity compensation is divided into performance-based and time-based restricted stock units. Under the program, the Compensation Committee sets the performance-based goals within the first 90 days of each year.

On March 30, 2015, the Compensation Committee granted 52,476 performance-based restricted stock units ("PSU's") to certain officers of the Company. Vesting of the PSU's is contingent upon the employee's continued employment and the Company's achievement of certain performance goals during a three-year performance period. The performance goals are established by the Compensation Committee and for the 2015-2017 performance period are based on financial targets, including an average annual return on invested capital (“ROIC”) and average annual growth in earnings before interest, taxes, depreciation and amortization (adjusted to exclude the effect of acquisitions, dispositions, and certain other nonrecurring or extraordinary items) (“Adjusted EBITDA”). We recognize compensation expense, net of estimated forfeitures, for PSU's on a straight-line basis over the performance period based on the probable outcome of achievement of the financial targets. At the end of each reporting period, we estimate the number of PSU's expected to vest, based on the probability and extent to which the performance goals will be met, and take into account these estimates when calculating the expense for the period. If the number of shares expected to be earned changes during the performance period, we will make a cumulative adjustment to compensation expense based on the revised number of shares expected to be earned.

Also on March 30, 2015 in conjunction with the grant of PSU's, the Compensation Committee granted a total of 29,644 time-based restricted stock units to the same officers of the Company. Vesting of the time-based restricted stock units is subject to the employee's continued employment through December 31, 2017.
