Employee Benefit Plans

Employee Benefit PlansThe Corporation sponsors a contributory defined contribution Section 401(k) plan. The plan permits eligible employees to make pre-tax and Roth contributions up to 70% of salary. Employees 21 years of age or over with a minimum of one-year with 1,000 hours of service are eligible for matching contributions by the Corporation at 100% for every 1% contributed up to 3% then 50% for every 1% contributed up to the next 2% in total of the employee’s compensation. The Corporation’s matching contribution and related expenses were $1.6 million, $1.2 million and $1.1 million for the years ended December 31, 2022, 2021, and 2020, respectively. A profit sharing discretionary non-contributory pension plan component is in place for employees 21 years of age or over with a minimum of one-year with 1,000 hours of service and allows employer contributions in an amount equal to a percentage of eligible compensation plus 5.7% of the compensation in excess of $147 thousand, subject to a $305 thousand salary limit. The Corporation recognized profit sharing expense of $2.9 million, $2.0 million and $1.9 million for the year ended December 31, 2022, 2021, and 2019 respectively.

The Corporation has adopted a non-qualified supplemental executive retirement plan ("SERP") for certain executives to compensate those executive participants in the Corporation’s retirement plan whose benefits are limited by compensation limitations under current tax law. The SERP is considered an unfunded plan for tax and ERISA purposes and all obligations arising under the SERP are payable from the general assets of the Corporation. At December 31, 2022 and 2021, obligations of $9.7 million and $8.8 million, respectively, were included in other liabilities for this plan. Expenses related to this plan were $1.3 million for the year ended December 31, 2022, $2.1 million for the year ended December 31, 2021 and $992 thousand for the year ended December 31, 2020.

The Corporation has established a Survivor Benefit Plan for the benefit of outside directors. The purpose of the plan is to provide life insurance benefits to beneficiaries of the Corporation’s directors who at the time of their death are participants in the plan. The plan is considered an unfunded plan for tax and ERISA purposes and all obligations arising under the plan are payable from the general assets of the Corporation. At December 31, 2022 and 2021, obligations of $1.6 million and $1.5 million, respectively, were included in other liabilities for this plan. Expenses (benefits) related to this plan were $81 thousand for the year ended December 31, 2022, $196 thousand for the year ended December 31, 2021 and $253 thousand for the year ended December 31, 2020.

On December 31, 2021, the Corporation adopted a Defined Contribution Plan for several employees (the "Plan"), pursuant to which the Corporation will make certain annual contributions to the Plan on the employee's behalf, which will be paid to the employee following their termination of employment from the Corporation or, if earlier, upon the employee becoming disabled. The Plan became effective as of January 2, 2022.

The Corporation has an unfunded post-retirement benefits plan which provides certain health care benefits for retired employees who have reached the age of 60 and retired with 30 years of service. The plan was amended in 2013 to include only employees hired prior to January 1, 2000. Benefits are provided for these retired employees and their qualifying dependents from the age of 60 through the age of 65.
