​ Employee Retirement Plan: The Company has a funded noncontributory defined benefit retirement plan covering substantially all of its salaried employees who were hired before September 1, 2005 (the “Retirement Plan”). The benefits are based on years of service and the employee’s compensation during the three consecutive years out of the final ten years of service, which was completed prior to September 30, 2006, the date the Retirement Plan was frozen, that produces the highest average. The Bank’s funding policy is to contribute annually the amount recommended by the Retirement Plan’s actuary. At December 31, 2024 and 2023, the Bank's Retirement Plan is invested 100% in fixed income funds. The Company did not make a contribution to the Retirement Plan during the years ended December 31, 2024, 2023, and 2022. Net pension (benefit) expense is recorded in salaries and employee benefits on the Consolidated Statements of Operations. The Company uses a December 31 measurement date for the Retirement Plan. The following table sets forth, for the Retirement Plan, the change in benefit obligation and assets, and for the Company, the amounts recognized in the Consolidated Statements of Financial Condition at December 31: ​

​ The long-term rate of return on assets assumption was set based on historical returns earned by fixed income securities, adjusted to reflect expectations of future returns as applied to the plan’s target allocation of asset classes. Fixed income securities were assumed to earn real rates of return in the ranges of 3-5%. When these overall return expectations are applied to the plans target allocation, the result is an expected rate return of 5.00% for 2024. The Retirement Plan’s weighted average asset allocations by asset category at December 31: ​

​ At December 31, 2024, Plan assets are invested in a diversified mix of fixed income funds. The long-term investment objectives are to maintain plan assets at a level that will sufficiently cover long-term obligations and to generate a return on plan assets that will meet or exceed the rate at which long-term obligations will grow. Adjustments to this mix are made periodically based on current capital market conditions and plan funding levels. Performance of the investment fund managers is monitored on an ongoing basis using modern portfolio risk analysis and appropriate index benchmarks. The Company does not expect to make a contribution to the Retirement Plan in 2025. The following table sets forth the Retirement Plan’s assets at the periods indicated: ​

The fair value of the mutual fund is determined daily using quoted market prices in an open market (level 1). The fair value of the pooled separate accounts is determined by the investment manager and is based on the value of the underlying assets held at December 31, 2024 and 2023. These are measured at net asset value under the practical expedient with future redemption dates. The fair values of the Plan’s investments in pooled separate accounts are calculated each business day. All investments can be redeemed on a daily basis without restriction. The investments in pooled separate accounts, which are valued at net asset value, have not been classified in the fair value hierarchy in accordance with Accounting Standards Update (“ASU”) No. 2015-07 “Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)”. ​ Other Postretirement Benefit Plans: The Company sponsors two unfunded postretirement benefit plans (the “Postretirement Plans”) that cover all retirees hired prior to January 1, 2011, who were full-time permanent employees with at least five years of service, and their spouses. Effective January 1, 2011, the Postretirement Plans are no longer available for new hires. One plan provides medical benefits through a 50% cost sharing arrangement. Effective January 1, 2000, the spouses of future retirees were required to pay 100% of the premiums for their coverage. The other plan provides life insurance benefits and is noncontributory. Effective January 1, 2010, life insurance benefits are not available for future retirees. Under these programs, eligible retirees receive lifetime medical and life insurance coverage for themselves and lifetime medical coverage for their spouses. Net postretirement (benefit) expense is recorded in salaries and employee benefits on the Consolidated Statements of Operations. The Company reserves the right to amend or terminate these plans at its discretion. Comprehensive medical plan benefits equal the lesser of the normal plan benefit or the total amount not paid by Medicare. Life insurance benefits for retirees are based on annual compensation and age at retirement. As of December 31, 2024, the Company has not funded these plans. The Company used a December 31 measurement date for these plans.

​ Defined Contribution Plans: The Bank maintains a tax qualified 401(k) plan which covers substantially all salaried employees who have completed one year of service. Currently, annual matching contributions under the Bank’s 401(k) plan equal 50% of the employee’s contributions, up to a maximum of 3% of the employee’s base salary. In addition, the 401(k) plan includes the Defined Contribution Retirement Plan (“DCRP”), under which the Bank contributes an amount equal to 4% of an employee’s eligible compensation as defined in the plan, and the Profit Sharing Plan (“PSP”) under, which at the discretion of the Company’s Board of Directors, a contribution is made. Employees hired after December 31, 2019 are not eligible to receive DCRP and PSP contributions. Contributions for the DCRP and PSP are made in the form of Company common stock at or after the end of each year. Annual contributions under these plans are subject to the limits imposed under the Internal Revenue Code. Contributions by the Company into the 401(k) plan vest 20% per year over the employee’s first five years of service. Contributions to these plans are 100% vested upon a change of control (as defined in the applicable plan). Compensation expense recorded by the Company for these plans amounted to $4.6 million, $3.4 million, and $4.7 million for the years ended December 31, 2024, 2023, and 2022, respectively. The Bank provides a non-qualified deferred compensation plan as an incentive for officers who have achieved the designated level and completed one year of service. In addition to the amounts deferred by the officers, the Bank matches 50% of their contributions, generally up to a maximum of 5% of the officers’ base salary. Matching contributions under this plan vest 20% per year for five years. The non-qualified deferred compensation plan assets are held in a rabbi trust totaling $21.1 million and $18.9 million at December 31, 2024 and 2023, respectively. Contributions become 100% vested upon a change of control (as defined in the plan). Compensation expense recorded by the Company for this plan amounted to $0.5 million for each of the years 2024, 2023, and 2022. Outside Director Retirement Plan: The Bank has an unfunded noncontributory defined benefit Outside Director Retirement Plan (the “Directors’ Plan”), which provides benefits to each non-employee director who became a non-employee director before January 1, 2004. Upon termination an eligible director will be paid an annual retirement benefit equal to $48,000. Such benefit will be paid in equal monthly installments for 120 months. In the event of a termination of Board service due to a change of control, an eligible non-employee director will receive a cash lump sum payment equal to 120 months of benefit. In the event of the director’s death, the surviving spouse will receive the equivalent benefit. No benefits will be payable to a director who is removed for cause. The Holding Company has guaranteed the payment of benefits under the Directors’ Plan, for this reason the Bank has assets held in a rabbi trust totaling $2.1 million and $2.0 million at December 31, 2024 and 2023, respectively. Net pension (benefit) expense is recorded in other operating expense on the Consolidated Statements of Operations. The Bank uses a December 31 measurement date for the Directors’ Plan.
