Postretirement Benefits Other Than Pensions PENSION BENEFITS
The Company previously sponsored a qualified defined benefit pension plan (the “Pension Plan”). Effective January 1, 2006, the Pension Plan was closed to new hires and, effective June 30, 2016, benefit accruals were frozen for substantially all of the participants under the Pension Plan. The Pension Plan has since been fully terminated.
During 2023, all plan liabilities were settled by either a lump-sum distribution or assumed by a third-party in exchange for a transfer of assets from the pension plan trust fund. After giving effect to these transactions, the Company
NOTE 19. PENSION BENEFITS (Continued)
recorded a $70.2 million noncash settlement charge ($55.5 million after-tax) for the unamortized net unrecognized postretirement benefit costs related to the settled obligations. Subsequently, during 2024, the Company received $2.6 million as a post-settlement adjustment which was recorded in Insurance and Other Expenses in the accompanying Consolidated Statements of Income (Loss).
During 2024, the Company distributed $4.7 million to eligible participants in the Company’s defined contribution benefit plans and reverted the remaining $13.1 million of assets for general corporate use. The Company incurred $7.3 million of pre- and post-tax expenses related to the reversion of assets within the pension trust, which included $4.7 million distributed to eligible participants in the Company’s defined contribution benefit plans and $2.6 million of excise taxes paid by the Company on the remaining $13.1 million made available for general corporate use. As of December 31, 2024, no assets remained in the pension trust.

Postretirement Benefits Other Than Pensions POSTRETIREMENT BENEFITS OTHER THAN PENSIONS
Kemper and Infinity Property and Casualty Corporation (“Infinity”) sponsor other than pension postretirement employee benefit plans (“OPEB”) that together provide medical, dental and/or life insurance benefits to approximately 300 retired and 100 active employees.
NOTE 20. POSTRETIREMENT BENEFITS OTHER THAN PENSIONS (Continued)
Kemper has historically self-insured the benefits under the Kemper OPEB Plan. The Kemper medical plan generally provides for a limited number of years of medical insurance benefits at retirement based on the participant’s attained age at retirement and number of years of service until specified dates and generally has required participant contributions, with most contributions adjusted annually. On December 30, 2016, Kemper amended the Kemper OPEB Plan and, effective December 31, 2016, no longer offers coverage to post-65 Medicare-eligible retirees and Medicare-eligible spouses under the self-insured portion of its coverage. Rather, beginning on January 1, 2017, the Kemper OPEB Plan offers access to a private, third-party Medicare exchange and provides varying levels of a Company-determined subsidy via health reimbursement accounts to certain Medicare-eligible retirees and spouses in order to help fund a portion of the participants’ cost. Further, the amendment eliminates the requirement for such participants to contribute to the Kemper OPEB Plan.
In conjunction with the amendment, the Company recorded a pre-tax reduction to its Accumulated Postretirement Benefit Obligation of $11.0 million through Other Comprehensive (Loss) Income. This prior service credit is being amortized into income over the remaining average life of the Kemper OPEB Plan’s participants.
