Post-Retirement Benefits

Note 19—Post-Retirement Benefits

At December 31, 2020, the Company and its subsidiary have two post-retirement health and life insurance benefit plans, South State Bank Retiree Medical Plan (the “retiree medical plan”) and the First Federal Retiree Welfare Plan (the “retiree welfare plan”).

Retiree Medical Plan

Under the retiree medical plan, post-retirement health and life insurance benefits are provided to eligible employees, such benefits being limited to those employees of the Company eligible for early retirement under the pension plan on or before December 31, 1993, and former employees who are currently receiving benefits. The plan was unfunded at December 31, 2020, and the liability for future benefits has been recorded in the consolidated financial statements.

The following sets forth the retiree medical plan’s funded status and amounts recognized in the Company’s accompanying consolidated financial statements:

​

​	​	​	​	​	​	​	​	​	​	​

Employer contribution	​		32	​		33	​		41	​

Fair value of plan assets at end of year	​		—	​		—	​		—	​
Funded status	​	$	(209)	​	$	(254)	​	$	(309)	​

​

Weighted-average assumptions used to determine benefit obligations and net periodic benefit cost are as follows:

​

​	​	​	​	​	​	​	​
​	​	Year Ended December 31,
​	​	2020	​	2019	​	2018
Weighted-average assumptions used to determine benefit obligation at December 31:							​
Discount rate		1.60	%	2.70	%	3.80	%
Weighted-average assumptions used to determine net periodic benefit cost for years ended December 31:	​	​	​	​	​	​	​
Discount rate		2.70	%	3.80	%	3.20	%
Assumed health care cost trend rates at December 31:	​	​	​	​	​	​	​
Health care cost trend rate assumed for next year		5.00	%	5.00	%	5.00	%

​

Components of net periodic benefit cost and other amounts recognized in other comprehensive income are as follows:

​

​	​	​	​	​	​	​	​	​	​	​
​	​	Year Ended December 31,
(Dollars in thousands)	​	2020		​	2019		​	2018
Interest cost		$	6		$	11		$	10	​
Recognized net actuarial loss	​		2	​		6	​		6	​
Net periodic benefit cost	​		8	​		17	​		16	​
Net (gain) loss	​		(19)	​		(33)	​		2	​
Amortization of gain	​		(2)	​		(6)	​		(6)	​
Total amount recognized in other comprehensive income	​		(21)	​		(39)	​		(4)	​
Total recognized in net periodic benefit cost and other comprehensive income	​	$	(13)	​	$	(22)	​	$	12	​

​

There is no estimated net loss for the retiree medical plan that will be amortized from other comprehensive income into periodic benefit cost over the next fiscal year.

Assumed health care cost trend rates have a significant effect on the amounts reported for the post-retirement benefit plan. A one-percentage point change in assumed health care cost trend rates would have the following effects at the end of 2020:

​

​	​	​	​	​	​	​	​
​	​	One-Percentage Point
(Dollars in thousands)	​	Increase		​	Decrease
Effect on total of interest cost		$	1		$	(1)	​
Effect on postretirement benefit obligation	​		10	​		(10)	​

​

Estimated future benefit payments (including expected future service as appropriate):

​

​	​	​	​	​
(Dollars in thousands)			​
2021	​	$	27	​
2022	​		25	​
2023	​		24	​
2024	​		22	​
2025	​		20	​
2026-2030	​		71	​
​	​	$	189	​

​

The Company expects to contribute approximately $27,000 to the retiree medical plan in 2021.
