Stock-Based Compensation

6 Months Ended

Jun. 30, 2018

STOCK-BASED COMPENSATION

The Company applies the provisions of ASC 718, “Compensation – Stock Compensation,” to account for the Company’s stock-based compensation. Stock-based compensation cost is measured at the grant date based on the calculated fair value of the award and is recognized over the employees’ requisite service period. The Company recorded stock compensation expense related to fully-vested stock awards, restricted stock awards, and performance unit awards of $822 and $558 for the three-month periods ended June 30, 2018 and 2017, respectively, and $1,904 and $725 for the six-month periods ended June 30, 2018 and 2017, respectively. At June 30, 2018, unrecognized compensation expense for awards that the Company expects to vest approximated $5,561. The Company will recognize this expense over the upcoming 3.8 years through April 2022.

Shares issued as a result of vested stock-based compensation awards generally will be from previously issued shares that have been reacquired by the Company and held as treasury stock or authorized and previously unissued common stock.

Restricted Stock Awards and Performance Unit Awards

Under the 2006 Omnibus Plan, the Company grants eligible employees restricted stock and performance unit awards. The forfeitable restricted stock awards granted prior to March 2015 generally time-vest after a four-year period, and those granted subsequent to March 2015 generally time-vest ratably over a three-year period, unless indicated otherwise by the underlying restricted stock agreement. Since May 2018, awards of restricted stock are subject to a minimum one-year vesting period, including those granted to non-employee directors. Prior to May 2018, awards to non-employee directors were made in fully-vested shares. Performance unit awards are offered annually under separate three-year long-term incentive programs. Performance units are subject to forfeiture and will be converted into common stock of the Company based upon the Company’s performance relative to performance measures and conversion multiples, as defined in the underlying program. If the Company’s estimate of the number of performance stock awards expected to vest changes in a subsequent accounting period, cumulative compensation expense could increase or decrease. The change will be recognized in the current period for the vested shares and would change future expense over the remaining vesting period.

Since May 1, 2017, non-employee directors have been permitted to defer receipt of annual stock awards and equity elected to be received in lieu of quarterly cash compensation. If so elected, these deferred stock units will be issued as common stock six months after the separation from their service on the Board of Directors.

During the quarter ended March 31, 2018, the Compensation Committee approved the 2018 Performance Share Unit Program and the Executive Annual Incentive Compensation Plan (consisting of cash and equity components). The Compensation Committee also certified the actual performance achievement of participants in the 2015 Performance Share Unit Program. Actual performance resulted in no payout relative to the 2015 Performance Share Unit Program target performance metrics.
