RETIREMENT AND POSTRETIREMENT PLANS |
RETIREMENT AND POSTRETIREMENT PLANS | 14. RETIREMENT AND POSTRETIREMENT PLANS The Bank maintains two noncontributory pension plans that existed before the Merger: (i) the Retirement Plan of Dime Community Bank (“Employee Retirement Plan”) and (ii) the BNB Bank Pension Plan, covering all eligible employees. ​ Employee Retirement Plan The Bank sponsors the Employee Retirement Plan, a tax-qualified, noncontributory, defined-benefit retirement plan. Prior to April 1, 2000, substantially all full-time employees of at least 21 years of age were eligible for participation after one year of service. Effective April 1, 2000, the Bank froze all participant benefits under the Employee Retirement Plan. On December 21, 2023, the Company’s Board of Directors adopted a resolution to terminate the Employee Retirement Plan effective December 31, 2023. Retirement benefits of the plan were vested as they were earned. For the year ended December 31, 2023, the Bank used December 31st as its measurement date for the Employee Retirement Plan. BNB Bank Pension Plan During 2012, Bridge Bancorp, Inc., (“Bridge”) amended the BNB Bank Pension Plan by revising the formula for determining benefits effective January 1, 2013, except for certain grandfathered Bridge employees. Additionally, new Bridge employees hired on or after October 1, 2012 were not eligible for the BNB Bank Pension Plan. Effective December 31, 2023, the Bank froze all participant benefits under the BNB Pension Plan, the impact of which is reflected in the recorded curtailment as of December 31, 2023. On December 21, 2023, the Company’s Board of Directors adopted a resolution to terminate the BNB Bank Pension Plan effective December 31, 2023. Retirement benefits of the plan were vested as they were earned. For the year ended December 31, 2023, the Bank used December 31st as its measurement date for the BNB Bank Pension Plan. The following tables represent the components of net periodic (credit) benefit cost included in other non-interest expense, except for service cost, which is reported in salaries and employee benefits expense, in the Consolidated Statements of Operations. Net expenses associated with these plans were comprised of the following components: ​

​ There were no contributions to the BNB Bank Pension Plan or the Employee Retirement Plan for the three or nine months ended September 30, 2024. ​ 401(k) Plan The Company maintains a 401(k) Plan (the “401(k) Plan”) that existed before the Merger. The 401(k) Plan covers substantially all current employees. Newly hired employees are automatically enrolled in the plan on the first day of the month following the 60th day of employment, unless they elect not to participate. Participants may contribute a portion of their pre-tax base salary, generally not to exceed $23,000 for the calendar year ended December 31, 2024. Under the provisions of the 401(k) Plan, employee contributions are partially matched by the Bank as follows: 100% of each employee’s contributions up to 1% of each employee’s compensation plus 50% of each employee’s contributions over 1% but not in excess of 6% of each employee’s compensation for a maximum contribution of 3.5% of a participating employee’s compensation. Participants can invest their account balances into several investment alternatives. The 401(k) Plan does not allow for investment in the Company’s common stock. The 401(k) Plan held Company common stock within the accounts of participants totaling $6.3 million at September 30, 2024. During the three and nine months ended September 30, 2024, total expense recognized as a component of salaries and employee benefits expense for the 401(k) Plan was $566 thousand and $2.2 million, respectively. During the three and nine months ended September 30, 2023, total expense recognized as a component of salaries and employee benefits expense for the 401(k) Plan was $513 thousand and $2.0 million, respectively. ​
