Employee Benefit Plans

The Company provides a contributory trusteed 401(k) deferred compensation and profit sharing plan, which covers substantially all employees. The Company agrees to match certain employee contributions under the 401(k) portion of the plan, while profit sharing contributions are discretionary and are subject to determination by the Board of Directors. Company contributions were $1,328, $1,121, and $999 for 2017, 2016, and 2015, respectively.

The Company self-insures employee health benefits. Stop loss insurance covers annual losses exceeding $150 per covered family as well as an aggregating specific deductible of $255 for the Company. Management’s policy is to establish a reserve for claims not submitted by a charge to earnings based on prior experience. Charges to earnings were $4,192, $3,153, and $2,666 for 2017, 2016, and 2015, respectively.

The Company maintains deferred compensation plans for the benefit of certain directors and officers. Under the plans, the Company agrees in return for the directors and officers deferring the receipt of a portion of their current compensation, to pay a retirement benefit computed as the amount of the compensation deferred plus accrued interest at a variable rate. Accrued benefits payable totaled $1,896 and $1,882 at December 31, 2017 and 2016. Deferred compensation expense was $187, $297, and $149 for 2017, 2016, and 2015, respectively. In conjunction with the plans, the Company purchased life insurance on certain directors and officers.

The Company entered into early retirement agreements with certain officers of the Company. Accrued benefits payable as a result of the agreements totaled $84 and $136 at December 31, 2017 and 2016, respectively. Expense associated with these agreements totaled $48, $0, and $215 during 2017, 2016, and 2015, respectively. The benefits under the agreements will be paid through 2018.

Multi-Employer Pension Plan

Through the acquisition of River Valley Bancorp, the Company acquired a participation in a multi-employer defined benefit pension plan. Effective December 31, 2015, the plan was frozen. Pension expense was approximately $63 and $54 during 2017 and 2016, respectively. Specific plan asset and accumulated benefit information for the Company's portion of the fund is not available. Under the Employee Retirement Income and Security Act of 1974 ("ERISA"), a contributor to a multi-employer pension plan may be liable in the event of complete or partial withdrawal for the benefit payments guaranteed under ERISA, but currently there is no intention to withdraw.

The Company participates in the Pentegra Defined Benefit Plan for Financial Institutions (the "Pentegra DB Plan"), 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 ERISA and the Internal Revenue Code. There are no collective bargaining agreements in place that require contributions to the Pentegra DB Plan.

The Pentegra DB Plan is a single plan under Internal Revenue Code Section 413(c) and, as a result, all of the assets stand behind all of the liabilities. Accordingly, under the Pentegra DB Plan, contributions made by a participating employer may be used to provide benefits to participants of other participating employers.

Total contributions made to the Pentegra DB Plan, as reported on Form 5500, equal $153,186 and $163,183 for the plan years ended June 30, 2016 and 2015, respectively. The Company's contributions to the Pentegra DB Plan for the fiscal year ending December 31, 2017 were not more than 5% of total contributions to the Pentegra DB Plan.
