Retirement Benefits, Description [Abstract] |
Employee Benefit Plans | Employee Benefit Plans 401(k) Plan The Bank has a defined contribution plan available to substantially all employees who have completed 3 months of service. Employees may contribute up to Internal Revenue Service ("IRS") determined limits and the Bank may match employee contributions not to exceed 3.0% of compensation depending on contribution level. Subject to a vote of the Board of Directors, the Bank may also make a profit-sharing contribution to the Plan. Such contribution equaled 2.0% of each eligible employee's compensation in 2017. The amount for 2018 has not been established. The expense related to the 401(k) plan was $414,000 and $364,000 for the nine months ended September 30, 2018 and 2017, respectively. Deferred Compensation and Supplemental Retirement Benefits The Bank also provides unfunded supplemental retirement benefits for certain officers, payable in installments over 20 years upon retirement or death. The agreements consist of individual contracts with differing characteristics that, when taken together, do not constitute a postretirement plan. The costs for these benefits are recognized over the service periods of the participating officers in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 712 "Compensation – Nonretirement Postemployment Benefits". The expense of these supplemental retirement benefits was $129,000 for the nine months ended September 30, 2018 and $161,000 for the the same period in 2017. As of September 30, 2018, the associated accrued liability included in other liabilities in the balance sheet was $2,973,000 compared to $3,060,000 and $3,040,000 at December 31, 2017 and September 30, 2017, respectively. Post-Retirement Benefit Plans The Bank sponsors two post-retirement benefit plans. One plan currently provides a subsidy for health insurance premiums to certain retired employees and a future subsidy for six active employees who were age 50 and over in 1996. These subsidies are based on years of service and range between $40 and $1,200 per month per person. The other plan provides life insurance coverage to certain retired employees and health insurance for retired directors. None of these plans are pre-funded. The Company utilizes FASB ASC Topic 712 to recognize the overfunded or underfunded status of a defined benefit postretirement plan as an asset or liability in its balance sheet and to recognize changes in the funded status in the year in which the changes occur through comprehensive income (loss). The following table sets forth the accumulated postretirement benefit obligation and funded status:
| At or for the nine months ended September 30,
| 2018 |  | 2017
Change in benefit obligation |  |  |
Benefit obligation at beginning of year | $ | 1,874,000 |  |  | $ | 1,870,000 |
Interest cost | 57,000 |  |  | 57,000 |
Benefits paid | (84,000 | ) |  | (96,000 | )
Benefit obligation at end of period | $ | 1,847,000 |  |  | $ | 1,831,000 |
Funded status |  |  |
Benefit obligation at end of period | $ | (1,847,000 | ) |  | $ | (1,831,000 | )
Unamortized loss | 186,000 |  |  | 156,000 |
Accrued benefit cost at end of period | $ | (1,661,000 | ) |  | $ | (1,675,000 | )
The following table sets forth the net periodic pension cost:
| For the nine months ended September 30, | For the quarter ended September 30,
| 2018 |  | 2017 | 2018 |  | 2017
Components of net periodic benefit cost |  |  |  |  |  |
Interest cost | $ | 57,000 |  |  | $ | 57,000 |  | $ | 19,000 |  |  | $ | 19,000 |
Net periodic benefit cost | $ | 57,000 |  |  | $ | 57,000 |  | $ | 19,000 |  |  | $ | 19,000 |
Amounts not yet reflected in net periodic benefit cost and included in accumulated other comprehensive income (loss) are as follows:
| September 30, 2018 |  | December 31, 2017 |  | September 30, 2017
Unamortized net actuarial loss | $ | (186,000 | ) |  | $ | (186,000 | ) |  | $ | (156,000 | )
Deferred tax benefit at 21% (for September 30, 2018 and December 31, 2017) and 35% (for September 30, 2017) | 39,000 |  |  | 39,000 |  |  | 54,000 |
Net unrecognized postretirement benefits included in accumulated other comprehensive income (loss) | $ | (147,000 | ) |  | $ | (147,000 | ) |  | $ | (102,000 | )
A weighted average discount rate of 4.25% was used in determining the accumulated benefit obligation and the net periodic benefit cost. The assumed health care cost trend rate is 7.0%. The measurement date for benefit obligations was as of year-end for prior years presented. The expected benefit payments for all of 2018 are $128,000. Plan expense for 2018 is estimated to be $77,000. A 1% change in trend assumptions would create an approximate change in the same direction of $100,000 in the accumulated benefit obligation, $7,000 in the interest cost and $1,000 in the service cost.
