As of September 30, 2022, unrecognized equity-based compensation expense related to unvested stock options and unvested RSUs was $2.3 million and $7.8 million, respectively. This is expected to be recognized over the years 2022 through 2027.

Included in the above-noted stock options outstanding and stock compensation expense are performance-based stock options which vest only upon the achievement of certain targets. Performance-based stock options are generally granted at-the-money, contingently vest over a period of 1 to 2 years, depending on the nature of the performance goal, and have contractual lives of 10 years. These options were valued in the same manner as the time-based options, with the assumption that performance goals will be achieved. The inputs for expected volatility, expected dividends, and risk-free rate used in estimating those options’ fair value are the same as the time-based options issued under the Company's equity incentive plans. The expected term for performance-based stock options is 5 to 7 years. However, the Company only recognizes stock compensation expense to the extent that the targets are determined to be probable of being achieved, which triggers the vesting of the performance options.

During 2020, the Company granted 105,000 performance-based stock options. Of these performance-based stock options, performance obligations had been met for 90,000 options which became exercisable in a prior period. Of these performance-based stock options, 90,000 options expired during the nine months ended September 30, 2022. No performance-based stock options were outstanding as of September 30, 2022.

Included in the above-noted RSU and restricted stock award outstanding amounts are performance-based RSUs which vest only upon the achievement of certain targets. Performance-based RSUs contingently vest over a period of 1 to 3 years, depending on the nature of the performance goal, and have contractual lives of 10 years. These units were valued in the same manner as other RSUs, based on the published closing market price on the day before the grant date. However, the Company only recognizes stock compensation expense to the extent that the targets are determined to be probable of being achieved, which triggers the vesting of the performance options.

During 2020, the Company granted performance-based RSUs of which 165,974 were outstanding as of September 30, 2022. No changes occurred during the nine months ended September 30, 2022.

During 2021, the Company granted performance-based RSUs of which 111,806 were outstanding as of September 30, 2022. No changes occurred during the nine months ended September 30, 2022.
