Retirement Benefits [Abstract] |
Employee Benefit Plans | Note 10 Employee Benefit Plans Defined Benefit Plan The Company has a noncontributory defined-benefit pension plan (the “Plan”), which covers most of its employees. Effective December 31, 2016, the Plan was closed to all new participants. The Company accrues and makes contributions designed to fund normal service costs on a current basis using the projected unit credit with service proration method to amortize prior service costs arising from improvements in pension benefits and qualifying service prior to the establishment of the Plan over a period of approximately 30 years. A summary of the activity in the Plan’s projected benefit obligation, assets, funded status and amounts recognized in the Company’s consolidated balance sheets is as follows:

The following represent the major assumptions used to determine the projected benefit obligation of the Plan. For 2017, 2016 and 2015, the Plan’s expected benefit cash flows were discounted using the Citibank Above Median Curve. For 2017, the RP-2014 Mortality Table and the MP-2017 Mortality Improvement Table were used. For 2016, the RP-2014 Mortality Table and MP-2016 Mortality Improvement Table were used. For 2015, the RP-2014 Mortality Table and MP-2015 Mortality Improvement Table were used.

The accumulated benefit obligation was $85,236,000 and $74,425,000 as of December 31, 2017 and 2016, respectively. The Company does not expect to make a contribution to the Plan in 2018. The following pension benefit payments, which reflect expected future service, as appropriate, are expected to be paid by the Plan:
| Amount
2018 | $ | 2,679,000
2019 |  | 2,823,000
2020 |  | 3,045,000

2022 |  | 3,693,000
2023-2027 |  | 23,682,000
The Plan’s pension cost included the following components:

The following represent the major assumptions used to determine the net pension cost of the Plan:
|  | 2017 |  | 2016 |  | 2015
Weighted average discount rate |  | 4.25 | % |  | 4.50 | % |  | 4.00 | %

For 2017, the RP-2014 Mortality Table and the MP-2016 Mortality Improvement Table were used. For 2016, the RP-2014 Mortality Table and the MP-2015 Mortality Improvement Table were used. For 2015, the RP-2014 Mortality Tables and the MP-2014 Mortality Improvement scale were used. The investment objective for the Plan is to maximize total return with a tolerance for average risk. Asset allocation is a balance between fixed income and equity investments, with a target allocation of approximately 45% fixed income, 25% U.S. equity and 30% non-U.S. equity. Due to volatility in the market, this target allocation is not always desirable and asset allocations can fluctuate between acceptable ranges. The fixed income component is invested in pooled investment grade securities. The equity components are invested in pooled large cap, small/mid cap and non-U.S. stocks. The expected one-year nominal returns and annual standard deviations are shown by asset class below:
|  |  |  |  | One-Year Nominal |  | Annual Standard
Asset Class |  | % of Total Portfolio |  | Return |  | Deviation
Core Fixed Income |  | 51 | % |  | 4.55 | % |  | 4.55 | %
Large Cap U.S. Equities |  | 14 | % |  | 7.00 | % |  | 15.85 | %
Small Cap U.S. Equities |  | 5 | % |  | 8.10 | % |  | 19.70 | %
International (Developed) |  | 25 | % |  | 7.99 | % |  | 17.93 | %
International (Emerging) |  | 5 | % |  | 10.56 | % |  | 27.35 | %
Applying appropriate correlation factors between each of the asset classes the long-term rate of return on assets is estimated to be 6.50%. A summary of the fair value measurements by type of asset is as follows:

Supplemental Executive Retirement Plan The Company also has an unfunded supplemental executive retirement plan (“SERP”) which covers key executives of the Company whose benefits are limited by the Internal Revenue Service under the Company’s qualified retirement plan. The SERP is a noncontributory plan in which the Company’s subsidiaries make accruals designed to fund normal service costs on a current basis using the same method and criteria as the Plan. A summary of the activity in the SERP’s projected benefit obligation, funded status and amounts recognized in the Company’s consolidated balance sheets is as follows:

| Amount
2018 | $ | 314,000
2019 |  | 313,000
2020 |  | 311,000
2021 |  | 367,000
2022 |  | 711,000
2023-2027 |  | 3,813,000
