Defined Benefit Pension Plans and Defined Benefit Postretirement Plans Disclosure [Abstract] |
Pension and Postretirement Benefit Plans | Postretirement Benefit Plans The Company provides certain health care and life insurance benefits for nine retired employees who have met certain eligibility requirements. All other employees retiring after reaching age 65 and having at least 15 years of service with the Company will be allowed to stay on the Company’s group life and health insurance policies, but will be required to pay premiums. The Company’s share of the estimated costs that will be paid after retirement is generally being accrued by charges to expense over the employees’ active service periods to the dates they are fully eligible for benefits. Generally Accepted Accounting Principles (“GAAP”) requires the Company to recognize the funded status (i.e. the difference between the fair value of plan assets and the projected benefit obligations) of its postretirement benefit plans in the consolidated balance sheet, with a corresponding adjustment to accumulated other comprehensive income, net of taxes. The following amounts that have not been recognized in the net periodic benefit cost of the postretirement benefit plan for the year ended December 31, 2015 but are included in other comprehensive income: unrecognized net actuarial gain of $39 thousand. The transition obligation included in other comprehensive income and expected to be recognized in the net periodic benefit cost of the postretirement benefit plan during 2016 is $2 thousand. The following tables provide a reconciliation of the changes in the benefit obligations and fair value of assets for 2015, 2014, and 2013 and a statement of the funded status at December 31, 2015, 2014 and 2013 for the postretirement benefit plans of the Company. The Company uses a December 31st measurement date for its plans.

The benefit obligation for the postretirement benefit plan was calculated using a weighted average discount rate of 3.00% for 2015, 3.50% for 2014, and 2.75% for 2013. For measurement purposes, a 10.00% annual rate of increase in the per capita cost of covered health care benefits was assumed for 2016 and 2017, 8.00% for 2018 and 2019, and 6.00% for 2020 and thereafter. If these rates were increased by 1.00% in each year, the benefit obligation at December 31, 2015 would have increased by $5 thousand and the net periodic benefit cost for 2015 would have increased by less than $1 thousand. If these rates were decreased by 1.00% in each year, the benefit obligation at December 31, 2015 would have decreased by $4 thousand and the net periodic benefit cost for 2015 would have decreased by less than $1 thousand. Estimated future benefit payments at December 31, 2015, which reflect expected future service, as appropriate, were as follows:
| Postretirement Benefits

2016 | $ | 13 |
2017 | 13 |
