Note 7 - Share-based compensation
Share-based compensation represents the cost related to share-based awards, typically stock options or stock grants, granted to employees, non-employees, officers and directors. Share-based compensation is measured at grant date, based on the estimated aggregate fair value of the award on the grant date, and such amount is charged to compensation expense on a straight-line basis (net of estimated forfeitures) over the requisite service period. For the six month periods ended June 30, 2023 and 2022, share-based compensation expense of $1.8 million and $0.6 million, respectively, is reflected in Selling, general and administrative expenses in the consolidated Income Statements.
Share-based awards have historically been made as stock options, and recently also as stock grants, issued pursuant to the terms of the Company’s stock option and stock incentive plans (collectively, the “Plans”), described below. The Plans may be administered by the Board of Directors or the Compensation Committee of the Board or by another committee appointed by the Board from among its members as provided in the Plans. Presently, the Plans are administered by the Company’s Compensation Committee of the Board of Directors. As of June 30, 2023 there were an aggregate of 4,227,261 shares of the Company’s common stock available under the Plans for issuance for future stock option grants or other stock based awards.
Stock option awards, which allow the recipient to purchase shares of the Company’s common stock at a fixed price, are typically granted at an exercise price equal to the Company’s stock price at the date of grant. Typically, the Company’s stock option awards have vested from immediately to two years from the grant date and have had a contractual term ranging from three to ten years. ISOs granted under the Plans may not be granted at a price less than the fair market value of the common stock on the date of grant (or 110% of fair market value in the case of persons holding 10% or more of the voting stock of the Company). Nonqualified options granted under the Plans may not be granted at a price less than the fair market value of the common stock. Options granted under the Plans expire not more than ten years from the date of grant (five years in the case of ISOs granted to persons holding 10% or more of the voting stock of the Company).
Effective September 17, 2014, the Company adopted its 2014 Stock Incentive Plan (“2014 Plan”) pursuant to which 3,000,000 shares of common stock were reserved for issuance (i) upon the exercise of options, designated as either ISOs under the Code or nonqualified options, or (ii) as stock, deferred stock or other stock-based awards. ISOs may be granted under the 2014 Plan to employees and officers of the Company. Non-qualified options, stock, deferred stock or other stock-based awards may be granted to consultants, directors (whether or not they are employees), employees or officers of the Company. Stock appreciation rights may also be issued in tandem with stock options. Unless the 2014 Plan is sooner terminated, the ability to grant options or other awards under the 2014 Plan will expire on September 17, 2024.
Effective June 7, 2018, the Company adopted its 2018 Stock Incentive Plan (“2018 Plan”) pursuant to which 4,000,000 shares of common stock were reserved for issuance (i) upon the exercise of options, designated as either ISOs under the Code or nonqualified options, or (ii) as stock, deferred stock or other stock-based awards. ISOs may be granted under the 2018 Plan to employees and officers of the Company. Non-qualified options, stock, deferred stock or other stock-based awards may be granted to consultants, directors (whether or not they are employees), employees or officers of the Company. Stock appreciation rights may also be issued in tandem with stock options. Unless the 2018 Plan is sooner terminated, the ability to grant options or other awards under the 2018 Plan will expire on June 7, 2028.
