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 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 March 31, 2018, 319,301 RSUs had been granted of the 1,500,000 shares approved under the 2014 Plan. 65,793 shares had been granted of the 300,000 shares approved under the Directors' Plan. As of March 31, 2018, 338,375 unvested RSUs were outstanding under the Company’s long-term incentive plans.
