|Share-based Payment Arrangement [Abstract]|
|STOCK-BASED COMPENSATION||STOCK-BASED COMPENSATIONThe Stock Option Plan for Key Employees, as well as, the Non-Employee Director Stock Option Plan (hereinafter collectively referred to as the “Stock Option Plans”), were approved by the Company’s stockholders in July 2008. The Stock Option Plans allot for the issuance of up to 1,000,000 shares.
The Trecora Resources Stock and Incentive Plan (the “Plan”) was approved by the Company’s stockholders in June 2012. As amended, the Plan allots for the issuance of up to 2.5 million shares in the form of stock options or restricted stock unit awards.
The Company recognized stock-based compensation expense of approximately $0.6 million and $0.5 million for the three months and $1.7 million and $1.4 million for the nine months ended September 30, 2021 and 2020, respectively.
Stock Options and Warrant Awards
Stock options and warrants granted under the provisions of the Stock Option Plans permit the purchase of our common stock at exercise prices equal to the closing price of Company common stock on the date the options were granted. The options have terms of 10 years and generally vest ratably over terms of 4 to 5 years. There were no stock options or warrant awards issued during the three or nine months ended September 30, 2021 or 2020, respectively.
A summary of the status of the Company’s stock option and warrant awards is as follows:
The aggregate intrinsic value of options was calculated as the difference between the exercise price of the underlying awards and the quoted price of our common stock. At September 30, 2021, options to purchase approximately 0.1 million shares of common stock were in-the-money.
Since no options were granted, the weighted average grant-date fair value per share of options granted during the three and nine months ended September 30, 2021 and 2020, respectively, was zero.
The Company has no non-vested outstanding options as of September 30, 2021.
Restricted Stock Unit Awards
Generally, restricted stock unit awards are granted annually to officers and directors of the Company under the provisions of the Plan. Restricted stock units are also granted ad hoc to attract or retain key personnel, and the terms and conditions under which these restricted stock units vest vary by award. The fair market value of restricted stock units granted is equal to the Company’s closing stock price on the date of grant. Restricted stock units granted to directors vest ratably over a 1 year period, while restricted stock units granted to officers generally vest ratably over 3 years. Certain awards also include vesting provisions based on performance metrics measured over a 3 year period. Upon vesting, the restricted stock units are settled by issuing one share of the Company's common stock per unit.
