Retirement and employee benefit plans, description | The Pentegra DB Plan is a single plan under Internal Revenue Code Section 413(c) and, as a result, all of the assets stand behind all of the liabilities. Accordingly, under the Pentegra DB Plan contributions made by a participating employer may be used to provide benefits to participants of other participating employers. Total contributions made to the Pentegra DB Plan, as reported on Form 5500, equal $138.3 million and $164.6 million for the plan years ended June 30, 2019 and 2018, respectively. Our contributions for fiscal 2020 and 2019 were not more than 5% of the total contributions made to the Pentegra DB Plan. Pension expense is the net contributions, which are based upon covered employees’ ages and salaries and are dependent upon the ultimate prescribed benefits of the participants and the funded status of the plan. The Company recognized expense related to the plans totaling approximately $935,000 and $1.2 million for the fiscal years ended June 30, 2020 and 2019, respectively. There are no collective bargaining agreements in place that require contributions to the Pentegra DB Plan. As of July 1, 2019, the most recent period for which information is available, the Banks had an adjusted funding target attainment percentage (“AFTAP”) of 86.98%. There are no funding improvement plans or surcharges to participants. Effective July 1, 2016, sponsorship of the plan was transferred to the Company, benefits ratios were standardized and prospectively each bank will contribute to the plan based generally on its pro rata share of future benefits. Effective April 1, 2019, the Company elected to freeze benefits to its employee participants. |  |
