Pension and Other Postretirement Benefits Disclosure [Text Block]	Note 12. Supplemental Executive Retirement Plan The Bank has entered into Supplemental Executive Retirement and Death Benefit Agreements (the “SERP Agreements”) with certain of the Bank’s executive officers, which upon the executive’s retirement, will provide for a stated monthly payment for such executive’s lifetime, subject to certain death benefits described below. The retirement benefit is computed as a percentage of each executive’s projected average base salary over the five years preceding retirement, assuming retirement at age 67. The SERP Agreements provide that (a) the benefits vest ratably over six years of service to the Bank, with the executive receiving credit for years of service prior to entering into the SERP Agreement, (b) death, disability and change-in-control shall result in immediate vesting, and (c) the monthly amount will be reduced if retirement occurs earlier than age 67 for any reason other than death, disability or change-in-control. The SERP Agreements further provide for a death benefit in the event the retired executive dies prior to receiving 180 monthly installments, paid either in a lump sum payment or continued monthly installment payments, such that the executive’s beneficiary has received payment(s) sufficient to equate to a cumulative 180 monthly installments. The SERP Agreements are unfunded arrangements maintained primarily to provide supplemental retirement benefits and comply with Section 409A of the Internal Revenue Code. The Bank financed the retirement benefits by purchasing fixed annuity contracts with four insurance carriers totaling $11.4 million that have been designed to provide a future source of funds for the lifetime retirement benefits of the SERP Agreements. The primary impetus for utilizing fixed annuities is a substantial savings in compensation expenses for the Bank as opposed to a traditional SERP Agreement.
