Stock-Based Compensation

Stock-Based Compensation

Note 9. Stock-Based Compensation

We account for stock-based compensation in accordance with the provisions of ASC Topic 718, Compensation-Stock Compensation (“ASC 718”), which established accounting for stock-based awards exchanged for employee services. Stock-based compensation cost is measured at each grant date, based on the fair value of the award, and is recognized as expense over the employee’s requisite service period of the award. All of our stock compensation is accounted for as an equity instrument.

The following table summarizes compensation costs related to our stock-based awards (in thousands, except per share data):


		Three Months Ended						Nine Months Ended
		September 30,						September 30,
		2023			2022			2023			2022
Cost of revenue		$	102		$	51		$	310		$	277
Selling, general and administrative			639			806			1,926			2,480
Research and development			150			179			482			504
Net effect on net income (loss)		$	891		$	1,036		$	2,718		$	3,261

As of September 30, 2023, the unamortized compensation costs related to unvested stock options granted to employees under our stock option plan was approximately $18,000, net of estimated forfeitures of $2,000. These costs will be amortized on a straight-line basis over a weighted-average period of approximately 0.1 years and will be adjusted for subsequent changes in estimated forfeitures. We did not capitalize any stock-based compensation to inventory as of September 30, 2023 and December 31, 2022 due to the immateriality of the amount.

We estimate the fair value of stock options using the Black-Scholes option pricing model, consistent with the provisions of ASC 718. There were no options granted in the three and nine months ended September 30, 2023 and 2022.

The following table summarizes the stock option transactions during the nine months ended September 30, 2023 (in thousands, except per share data):

The aggregate intrinsic value in the table above represents the total pretax intrinsic value, based on our closing price of $2.40 on September 29, 2023, which would have been received by the option holder had all option holders exercised their options on that date.

At-Risk, Performance Shares

In February 2022 and March 2023, the Company issued at-risk, performance shares classified as equity awards. Expense is recognized quarterly on a straight-line method over the requisite service period, based on the probability of achieving the specified financial performance metric, with changes in expectations recognized as an adjustment to earnings in the period of change. Compensation cost is not recognized for at-risk, performance shares that do not vest because service or performance conditions are not satisfied and any previously recognized compensation cost is reversed. At-risk, performance shares are eligible to receive dividend equivalents under the Company’s 2015 Equity Incentive Plan (the “Plan”), as determined by the Board of Directors. The Company will recognize forfeitures as they occur.

The Company's at-risk, performance shares are classified as equity and contain performance and service conditions that must be satisfied for an employee to receive the shares. The financial performance metric for the at-risk, performance shares issued in February 2022 is based upon year-end 2021 actual results as compared to the Company’s year-end actual results in 2022. The financial performance metrics for the at-risk, performance shares issued in March 2023 are based upon the Company’s year-end actual results in 2023. All performance shares, if earned, are still subject to annual vesting over a four-year period, except that no shares are vested on the first anniversary because the performance measurement is based on year-end results for the year 2022 and 2023, respectively.

The fair value of the at-risk, performance shares is determined based on the closing price of the Company’s common stock on the first day after the public issuance of the Company’s earnings release for the most recent fiscal quarter, following the Compensation Committee and Board of Directors approval, which is considered the grant date. The fair value per share of the at-risk, performance shares classified as equity awards granted in February 2022 and March 2023 was $7.83 and $3.71, respectively.

On February 17, 2021, the Compensation Committee recommended, and the Board of Directors approved, the grant to Dr. Morris Young, our Chief Executive Officer, of 113,130 at-risk, performance shares under the Plan. On February 17, 2021, the Compensation Committee approved the grant to Gary Fischer, our Chief Financial Officer and Corporate Secretary, of 38,475 at-risk, performance shares under the Plan. On March 14, 2022, the Compensation Committee met and certified the year-over-year annual revenue growth rate achieved for fiscal year 2021, expressed as a percentage, was 44%. Therefore, all of the at-risk performance shares became eligible to vest.

On February 15, 2022, the Compensation Committee recommended, and the Board of Directors approved, the grant to Dr. Morris Young of 114,320 at-risk, performance shares under the Plan. On February 15, 2022, the Compensation Committee approved the grant to Gary Fischer of 32,100 at-risk, performance shares under the Plan. On February 14, 2023, the Compensation Committee met and certified the year-over-year annual revenue growth rate achieved for fiscal year 2022, expressed as a percentage, was 2.7%. Therefore, none of the at-risk performance shares became eligible to vest.

On March 15, 2023, the Compensation Committee recommended, and the Board of Directors approved, the grant to Dr. Morris Young of 223,590 at-risk, performance shares under the Plan. On March 15, 2023, the Compensation Committee approved, the grant to Gary Fischer of 77,600 at-risk, performance shares under the Plan. If the minimum financial metric is achieved, then based upon a performance formula, a corresponding portion of the 223,590 shares issued to Dr. Young would be eligible to vest and a corresponding portion of the 77,600 shares issued to Mr. Fischer would be eligible to vest. If the target financial metric is exceeded and an additional financial metric is achieved, additional shares above the target number of shares are earned based on such performance formula and the maximum number of additional shares earned is capped at 100% of the target. If the minimum financial metric is not achieved, then these awards are forfeited based upon the pre-determined revenue metric for the year ending December 31, 2023.
