Retirement Benefits [Abstract]
Benefit Plans	Benefit Plans Deferred Compensation Plans We established a Deferred Compensation Plan, which allows certain key management personnel designated by the Board of Directors of the Bank to defer up to 80% of their salary and 100% of their annual bonus. Amounts deferred earn interest that is equal to the prime rate as published in the Wall Street Journal, on the first business day of the year, which was 3.25% on January 1, 2022 and January 1, 2021. As part of the acquisition of AMRB in August 2021, we assumed $2.9 million of deferred compensation plans for former members of AMRB's management team and non-employee directors. Prior to January 1, 2022, amounts deferred earned interest based on the 5-year U.S. Government Treasury rate plus 4.0%. This rate was 4.36% for 2021. Beginning January 1, 2022, the rate converted to the prime rate. A similar Deferred Director Fee Plan, which allows members of the Board of Directors to defer the cash portion of their director compensation, went into effect on January 1, 2021, and the first deferral of their fees was in July 2021. Our deferred compensation obligation under these plans totaled $7.1 million and $7.9 million at December 31, 2022 and 2021, respectively, and is included in interest payable and other liabilities. 401(k) Defined Contribution Plan Our 401(k) Defined Contribution Plan, which includes a Roth 401(k) option (the “401(k) Plan”), is available to all regular employees at least eighteen years of age who complete ninety days of service, and enter the plan during one of the four open enrollment dates (January 1, April 1, July 1, and October 1) of each year. Under the 401(k) Plan, employees can defer between 1% and 50% of their eligible compensation, up to the maximum amount allowed by the Internal Revenue Code. The Bank provides employer-match of 70% of each participant's contribution, with a maximum of $5 thousand of matching contribution per participant per year. Employer matching contributions to the 401(k) Plan vest at a rate of 20% per year over five years, per plan provisions. Employer contributions totaled $949 thousand, $991 thousand and $929 thousand for the years ended December 31, 2022, 2021 and 2020, respectively, and are recorded as part of salaries and benefits expense. Employee Stock Ownership Plan Our Employee Stock Ownership Plan (the “Plan”) is also available to all employees under the same eligibility criteria of the 401(k) Plan; however, employee contributions are not permitted. The Board of Directors determines a specific portion of the Bank's profits to be contributed to the employee stock ownership each year either in common stock or in cash for the purchase of Bancorp stock to be allocated to all eligible employees based on a percentage of their salaries, regardless of whether an employee is participating in the 401(k) plan or not. For all participants, employer contributions vest over a five-year service period, per plan provisions. After five years of service, all employer contributions vest immediately. Bancorp issued shares of common stock, contributed them to the ESOP and recognized expenses of $1.6 million in 2022 and $1.3 million in 2021 and 2020, based on the quoted market price on the date of contribution. Cash dividends paid on Bancorp stock held by the ESOP are used to purchase additional shares in the open market. All shares of Bancorp stock held by the ESOP are included in the calculations of basic and diluted earnings per share. The employer contributions to the ESOP are included in salaries and benefits expense. Salary Continuation Plan A Salary Continuation Plan was established for a select group of executive management, who, upon retirement, will receive twenty-five percent of their estimated salary at retirement as salary continuation benefit payments that are fixed and will be made between five to fifteen years, depending on the executives' service period at the Bank. Each participant will need to participate in this plan for five years before vesting begins. After five years, the participant will vest ratably in the benefit over the remaining period until age 65. As part of previous acquisitions, we assumed the salary continuation agreements for former executive officers and directors. These plans are unfunded and nonqualified for tax purposes and for purposes of Title I of the Employee Retirement Income Security Act of 1974. At December 31, 2022 and 2021, respectively, our total liability under the salary continuation plans was $4.7 million and $5.3 million recorded in interest payable and other liabilities.
