As of June 30, 2023, the intrinsic value of the RSUs and PSUs outstanding and vested or expected to vest was $8.8 million. There was approximately $12.1 million of total compensation costs related to stock-based awards not yet recognized as of June 30, 2023, which is expected to be recognized on a straight-line basis over a weighted-average remaining vesting period of 0.7 years.

Stock Options

The Company uses the Black-Scholes option pricing model to calculate the estimated fair value of stock options on the date of grant. Option awards are generally granted with an exercise price equal to the market price of the Company's stock at the date of grant. The following weighted-average assumptions are used in the Black-Scholes valuation model to estimate the fair value of stock option awards, as granted.

•Expected term of the option – For options granted to employees and directors, the Company estimates the term over which option holders are expected to hold their stock option by using the "simplified method" in accordance with Staff Accounting Bulletin ("SAB") No. 107, Share-Based Payments, and SAB No. 110, Simplified Method for Plain Vanilla Share Options, to calculate the expected term of stock options determined to be "plain vanilla." The Company's stock option exercise history does not provide a reasonable basis to compute the expected term for stock options. Under this approach, the expected term is presumed to be a midpoint between the vesting date and the contractual end of the stock option grant. For options granted to non-employees, the Company elected to use the contractual term as the expected term.

•Risk-free interest rate – Based on the daily yield curve rates for U.S. Treasury obligations with terms that approximate the expected term of the stock options.

•Expected volatility – Due to the absence of the Company's historical price volatility for the expected contractual term of the stock options, the Company utilized the historical price volatility of a peer group.

•Expected dividend yield – The Company has not declared dividends, nor does it expect to in the foreseeable future. Therefore, a zero value was assumed for the expected dividend yield.

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying stock option awards and the quoted closing price of the Company's common stock as of June 30, 2023.

The fair value of the stock options is expensed on a straight-line basis over the vesting period of one year, including the stock options granted to directors, as the next annual stockholders meeting is expected to occur at the same approximate time each year.

During the three and six months ended June 30, 2023, the stock-based compensation expense on stock options recorded as part of general and administrative expenses was immaterial, with no similar expense in 2022. As of June 30, 2023, there were approximately $0.4 million of unrecognized compensation costs related to non-vested stock options.
