Share-Based Payment Arrangement, Recognized Amount [Abstract]

In February 2015, the Company's Board of Directors adopted the 2015 Incentive Award Plan (the "2015 Plan"), replacing the 2005 Equity Incentive Plan which expired in January 2015. The 2015 Plan was approved at the Company's Annual Meeting of Shareholders in May 2015. A maximum of 4,900,000 shares of common stock are authorized for issuance under the 2015 Plan upon exercise of stock options, stock appreciation rights and other awards, or upon vesting of restricted stock unit ("RSU") or deferred stock awards. The Company granted 80,000 stock options, 10,000 of which were forfeited, with 4,830,000 shares of common stock available for future grant under the 2015 Plan as of September 30, 2023.

Share-based compensation expenses for all stock options granted or modified are based on their estimated grant-date fair values. These compensation costs are recognized on a straight-line basis over the requisite service period of the award. The

Company estimates forfeitures expected to occur in determining the amount of compensation cost to be recognized in each period. As of September 30, 2023, all outstanding stock options have a term of ten years from the date of grant and become exercisable in four equal installments on the first through fourth anniversaries of the grant date. The fair value of stock option awards is estimated using the Black-Scholes option pricing model with the grant-date assumptions and weighted-average fair values.

In February 2018, the Compensation Committee of the Company's Board of Directors awarded a total of 80,000 stock options to four senior executives under the 2015 Plan, which vested over the four-year requisite service period, except for 10,000 of these stock options that were forfeited in February 2019 following the departure of a senior executive. The fair values of these stock options were estimated on the date of grant using a closed-form option valuation model (Black-Scholes).

The following table provides the assumptions used in the calculation of grant-date fair values of these stock options based on the Black-Scholes option pricing model:


Weighted-average grant-date fair value	$	8.09
Expected volatility	33.18		%
Risk-free interest rate	2.62		%
Expected dividend yield	5.40		%
Expected term in months	72

Expected volatilities are based on historical volatility of the Company’s stock over the term of the stock options. The expected term of stock options represents the period of time that stock options granted are expected to be outstanding, and is estimated based on historical exercise patterns and post-vesting termination behavior. The risk-free interest rate is determined based on U.S. Treasury yields with equivalent remaining terms in effect at the time of the grant.

As of September 30, 2023, the Company had no unrecognized compensation expense related to stock options awarded under the 2015 Plan.

No share-based compensation awards were granted during the nine months ended September 30, 2023.
