Employee and Non-Employee Benefit Plans

Employee and Non-Employee Benefit Plans.

Equity-Based Compensation Plans.  The Company’s equity-based compensation plans provide for the awarding of stock options, stock appreciation rights, shares of restricted stock ("Restricted Stock"), and restricted stock units ("RSUs") for senior executives and salaried employees, as well as non-employee directors. The Company has two active equity-based compensation plans: the Employee Equity Incentive Plan of 2014 (the "2014 Plan") and the Non-Employee Director Equity Incentive Plan (the "Directors' Plan"). The 2014 Plan replaced the inactive Stock Incentive Plan of 2004.

As of June 30, 2017, 280,074 RSUs had been granted under the 2014 Plan, with 14,616 of those forfeited for termination of employment. 62,995 shares had been granted related to the Directors' Plan as of June 30, 2017 and 497,492 shares of unvested RSUs were outstanding under the Company’s active and inactive long-term incentive plans.

As of June 30, 2017, the estimated unaccrued amount of liability-classified awards yet to be granted in 2018, net of estimated forfeitures, was $1,268.
