NOTE 13 – BENEFIT PLANS

Multi-employer pension plan:

CFBank participates in the Pentegra Defined Benefit Plan for Financial Institutions (the “Pentegra DB Plan”), a multi-employer contributory trusteed pension plan. The retirement benefits to be provided by the plan were frozen as of June 30, 2003 and future employee participation in the plan was stopped. The plan was maintained for all eligible employees and the benefits were funded as accrued. The cost of funding was charged directly to operations.

The unfunded liability under the Pentegra DB Plan at June 30, 2017 totaled $36 and at June 30, 2016 was $53. CFBank’s contributions for the plan years ending June 30, 2017 and June 30, 2016, totaled $32, and $42, respectively. Contributions to the plan may vary from period to period due to the change in the plan's unfunded liability. The unfunded liability is primarily related to the change in plan assets and the change in plan liability from one year to the next. The change in plan assets is based on contributions deposited, benefits paid and the actual rate of return earned on those assets. The change in plan liability is based on demographic changes and changes in the interest rates used to determine plan liability. In the event the actual rate of return earned on plan assets declines, the value of the plan assets will decline. In the event the interest rates used to determine plan liability decrease, plan liability will increase. The combined effect of each change determines the change in the unfunded liability and the change in the employer contributions.

The Pentegra DB Plan is a tax-qualified defined-benefit pension plan. The Pentegra DB Plan operates as a multi-employer plan for accounting purposes and as a multiple-employer plan under the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code.
