Defined Pension Plans

Note 9 – Defined Pension Plans

The Company has a noncontributory defined-benefit pension 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. Disclosure information is based on a measurement date of December 31 of the corresponding year. The following table represents the components of the net periodic pension costs:

	Estimated			Actual
(In thousands)	2018			2017
Service cost – benefits earned during the year	$	4,294		$	3,733
Interest cost on projected benefit obligations		3,655			3,621
Expected return on plan assets		(5,206	)		(4,681	)
Net amortization		1,409			1,382
Net periodic pension cost	$	4,152		$	4,055

Pension costs recorded to expense were $1,049,000 and $1,020,000 for the three-month periods ended March 31, 2018 and 2017, respectively. Pension costs increased in 2018 primarily due to a decrease in the discount rate. The Company made no contribution to the plan during the three-month period ended March 31, 2018 and is evaluating the amount of additional contributions, if any, in the remainder of 2018.

In addition to the above funded benefit plan, the Company has an unfunded supplemental executive retirement plan which covers key executives of the Company. This is a noncontributory plan in which the Company and its subsidiaries make accruals designed to fund normal service costs on a current basis using the same method and criteria as its defined benefit plan. The following table represents the components of the net periodic pension costs for 2017 and an estimate for 2018:

	Estimated		Actual
(In thousands)	2018		2017
Service cost – benefits earned during the year	$	92	$	143
Interest cost on projected benefit obligation		348		360
Net amortization		581		324
Net periodic pension cost	$	1,021	$	827

Pension costs recorded to expense were $255,000 and $209,000 for the three-month periods ended March 31, 2018 and 2017, respectively.
