Stock-Based Compensation

Stock-Based Compensation

The Company recognizes compensation expense for all stock-based awards granted to employees and directors based on the grant date estimate of fair value for those awards. The fair value of RSUs is based on the grant date price of the Company's common stock, reduced by the present value of estimated dividends foregone during the requisite service period. For time-based RSUs, compensation expense is recognized ratably over the requisite service period for the entire award based on the grant date fair value, and net of actual forfeitures recorded when they occur. For performance-based RSUs, compensation expense is recognized ratably over the requisite service period for each separately-vesting portion of the award based on the grant date fair value, net of actual forfeitures recorded when they occur and remeasured each reporting period until the total number of RSUs to be issued is known. The Company recognized stock-based compensation expense of $2,146,000 in the second quarter of 2018, $1,441,000 in the second quarter of 2017, $3,610,000 in the first six months of 2018 and $2,736,000 in the first six months of 2017 within selling, general, and administrative (SG&A) expenses in the accompanying condensed consolidated statement of income. Unrecognized compensation expense related to stock-based compensation totaled approximately $8,374,000 at June 30, 2018, and will be recognized over a weighted average period of 1.8 years.

On May 16, 2018, the Company granted 10,800 RSUs in the aggregate to its non-employee directors with a grant date fair value of $1,019,000. Half of these RSUs vested on June 1, 2018 and the remaining shares will vest ratably on the last day of the third and fourth fiscal quarters of 2018.
