Note 13. Employee Benefit Plans Pension Plans The Company maintains the Bremer Retirement Plan (“Pension Plan”), which is a qualified defined benefit pension plan designed to provide retirement benefits to substantially all the employees of the Company, its subsidiaries, and OBT. An employee who has attained the age of 21 and completed 1,000 hours of service within a 12-month period shall become a participant in the Pension Plan on the next semiannual entry date. In addition, the Company has a Supplemental Executive Retirement Plan (“SERP”), an unfunded plan designed to supplement the benefits determined under the Pension Plan for certain highly compensated employees of the Company to the extent the benefits under the Pension Plan are capped by compensation limits. Other Postretirement Benefits The Company provides certain retiree health care benefits relating primarily to medical insurance co-payments to retired employees between the ages of 55 and 65. The Company amended the Company’s Retiree Medical Plan effective January 1, 2006, which gradually eliminated the medical premium subsidy for retired employees over a period of ten years ending December 31, 2015, while continuing to allow retired employees access to the Company’s group medical coverage. The Company accrues the cost of these benefits during the employees’ active service, and benefits are funded as incurred. Pension Plans and Other Postretirement Benefits The Company recognizes actuarial gains or losses and prior service costs or credits, and measures plan assets and pension obligations, and accumulated other comprehensive income or loss, net of tax, at December 31 of each year. The Company expects to amortize the following amounts from accumulated
