2017 Omnibus Incentive Plan Description | The Company adopted an equity-based incentive plan in October 2017 (the 2017 Plan). Under the 2017 plan, the Company reserved for issuance 500,000 shares of common stock for awards to employees and directors, against which full value awards (stock-based awards other than stock options and stock appreciation rights) are to be counted on a 2.5-for-1 basis. The 2017 Plan authorized awards to be made to employees, officers, and directors by a committee of outside directors. The committee held the power to set vesting requirements for each award under the 2017 Plan. Under the 2017 Plan, stock awards and shares issued pursuant to exercised options may be issued from either authorized but unissued shares, or treasury shares. |  |
