In February 2022, our shareholders approved a proposal to authorize our 2021 Stock-Based Compensation Plan (“2021 Plan”), which replaced our 2011 Stock-Based Compensation Plan (“2011 Plan”). Our 2021 Plan provides for the grant of stock options, stock appreciation rights, restricted stock, stock units, bonus stock, dividend equivalents, other stock related awards, and performance awards (collectively “awards”), that may be settled in cash, stock, or other property. Our 2021 Plan is designed to attract, motivate, retain, and reward our executives, employees, officers, directors, and independent contractors by providing such persons with annual and long-term performance incentives to expend their maximum efforts in the creation of shareholder value. The total number of shares of our common

stock that may be subject to awards under the 2021 Plan is equal to 1,000,000 shares, plus: (i) any shares available for issuance and not subject to an award under the 2007 Plan or the 2011 Plan, which was 545,729 in aggregate at the time of the approval of the 2021 Plan; (ii) the number of shares with respect to which awards granted under the 2021 Plan, the 2011 Plan or the 2007 Plan terminate without the issuance of the shares or where the shares are forfeited or repurchased; (iii) with respect to awards granted under the 2021 Plan, the 2011 Plan and the 2007 Plan, the number of shares that are not issued as a result of the award being settled for cash or otherwise not issued in connection with the exercise or payment of the award; and (iv) the number of shares that are surrendered or withheld in payment of the exercise price of any award or any tax withholding requirements in connection with any award granted under the 2021 Plan, the 2011 Plan or the 2007 Plan. The 2021 Plan terminates in February 2032, and awards may be granted at any time during the life of the 2021 Plan. The dates on which awards vest are determined by the Board of Directors or the Plan Administrator. The Board of Directors has appointed the Compensation Committee as the Plan Administrator. The exercise prices of options are determined by the Board of Directors or the Plan Administrator and are at least equal to the fair market value of shares of common stock on the date of grant. The term of options under the 2021 Plan may not exceed ten years. The options granted have varying vesting periods. To date, we have not settled or been under any obligation to settle any awards in cash.

During the three months ended December 31, 2022, 5,000 options were granted. No options were granted for the three months ended December 31, 2021. The weighted average grant date fair value of options granted during the three months ended December 31, 2022 was $15.53. The total intrinsic value of options exercised during the three months ended December 31, 2021 and 2022, was $1.1 million and $0.1 million, respectively.

We used the Black-Scholes model to estimate the fair value of options granted. The expected term of options granted is estimated based on historical experience. Volatility is based on the historical volatility of our common stock. The risk-free rate for periods within the contractual term of the options is based on the U.S. Treasury yield curve in effect at the time of grant.
