SHARE-BASED COMPENSATION
We maintain a share-based compensation incentive plan that authorizes the granting of stock options, restricted stock, restricted stock units (“RSUs”), and other equity-based awards to employees and nonemployee directors. At December 31, 2025, a total of 7,100,000 shares were authorized under the plan, with 3,729,002 shares available for future grants.
All share-based payments to employees, including stock option grants, are recognized as compensation expense based on their grant date fair values and reflect any associated service or performance vesting requirements. The fair value of an equity award is estimated on the grant date using an appropriate valuation model, which incorporates post-vesting restrictions, but excludes service or performance vesting conditions.
All share-based awards are classified as equity instruments. Compensation expense is included in “Salaries and employee benefits” on the consolidated statement of income, with the corresponding equity effect included in shareholders’ equity. Forfeitures of share-based awards are recognized as they occur. Substantially all share-based awards—including stock options, restricted stock, and RSUs—feature graded vesting, which is recognized on a straight-line basis over the applicable vesting period.
The following schedule presents compensation expense and the related tax benefit for all share-based awards:
| | | | | | | | | | | | | | | | | |
| (In millions) | 2025 | | 2024 | | 2023 |
| | | | | |
| Compensation expense | $ | 35 | | | $ | 31 | | | $ | 33 | |
| Reduction of income tax expense | 10 | | | 7 | | | 9 | |
At December 31, 2025, the unrecognized compensation expense related to nonvested share-based awards was approximately $43 million. This amount is expected to be recognized over a weighted average period of 2.7 years.
Stock Options
Stock options granted to employees generally vest one-third per year and expire seven years after the grant date. No stock options were granted in 2025 or 2024 following management's changes to incentive compensation programs. For stock options granted in 2023, the Black-Scholes option pricing model was used to estimate the grant date fair value for purposes of determining compensation expense.
The following schedule presents the weighted average grant date fair value and the significant assumptions used in the Black-Scholes model for these options:
| | | | | | | | | | | | | | | | | |
| 2025 | | 2024 | | 2023 |
| | | | | |
| Weighted average value for options granted | $ | — | | | $ | — | | | $ | 11.23 | |
| Weighted average assumptions used: | | | | | |
| Expected dividend yield | — | % | | — | % | | 3.0 | % |
| Expected volatility | — | % | | — | % | | 27.0 | % |
| Risk-free interest rate | — | % | | — | % | | 4.00 | % |
| Expected life (in years) | 0.0 | | 0.0 | | 4.5 |
The assumptions for expected dividend yield, expected volatility, and expected life reflect management’s judgment and incorporate historical experience. Expected volatility is based in part on historical volatility. The risk-free interest rate is derived from the U.S. Treasury yield curve in effect at the grant date, matched to the expected life of the option.

We issue new authorized common shares upon the exercise of stock options. The total intrinsic value of stock options exercised was approximately $1 million in 2025, and $2 million in both 2024 and 2023. Cash received from the exercise of stock options totaled $5 million in 2025, $9 million in 2024, and $2 million in 2023.

1 The weighted average remaining contractual life excludes 5,223 stock options without a fixed expiration date that were assumed in the Amegy acquisition. These options expire one year after the employee's termination date, subject to certain conditions.
The aggregate intrinsic value of outstanding stock options was $7 million at December 31, 2025, compared with $4 million at December 31, 2024. The aggregate intrinsic value of exercisable options was $6 million and $4 million at those same respective dates. For exercisable options, the weighted average remaining contractual life was 2.2 years at December 31, 2025, and 2.6 years at December 31, 2024, excluding the stock options previously noted that do not have a fixed expiration date. At December 31, 2025, there were 92,559 unvested stock options outstanding, with a weighted average exercise price of $52.90, a weighted average remaining contractual life of 3.9 years, and an aggregate intrinsic value of $522 thousand.
Restricted Stock and Restricted Stock Units
Restricted stock represents common shares that are subject to trading restrictions and potential forfeiture. These awards typically vest over a four-year period. Holders of restricted stock have full voting rights and receive dividend equivalents during the vesting period. Additionally, holders may elect to be taxed on the grant date rather than at vesting.
RSUs represent the right to receive one share of common stock per unit and generally vest over a four-year period. Holders of RSUs receive dividend equivalents during the vesting period, but do not possess voting rights. Compensation expense is determined based on the number of restricted shares or RSUs granted and the market price of our common stock on the grant date. During 2025, 2024, and 2023, we granted 25,101, 25,866, and 39,771 RSUs, respectively, to nonemployee directors. These RSUs vested immediately upon grant.
