Primary Pension Plan Lump-Sum Payment Offer and VERP
In April 2020, the Company initiated a Voluntary Early Retirement Program (VERP) for approximately 4,300 eligible associates. Eligibility for the VERP included home office, stores and supply chain personnel who met certain criteria related to age and years of service as of October 23, 2019. The consideration period for eligible associates to accept the VERP ended on May 29, 2020. Based on the approximately 2,600 associates who elected to accept the VERP, we incurred a total charge of $94 million for enhanced retirement benefits. The enhanced retirement benefits increased the projected benefit obligation (PBO) of the Primary Pension Plan and the Supplemental Pension Plans by $85 million and $9 million, respectively. In addition, we incurred curtailment charges of $4 million related to our Primary Pension Plan and $1 million related to Supplemental Pension Plans as a result of the reduction in the expected years of future service related to these plans. As a result of these curtailments, the assets and the liabilities for our Primary Pension Plan and the liabilities of certain Supplemental Pension Plans were remeasured as of July 31, 2020. The discount rate used for the remeasurements was 2.64% compared to the fiscal year 2019 discount rate of 3.08%. The remeasurement and curtailment resulted in the PBO of our Primary Pension Plan increasing by
$117 million and the related assets increasing by $74 million, and the PBO of our Supplemental Pension Plans decreasing by $0.4 million.

During the third quarter of 2020, we remeasured the Plan assets and liabilities as a result of settlement accounting and recognized settlement expense of $16 million. Settlement accounting was due to lump-sum payment activity to retirees and other separated associates primarily as a result of the VERP, store closures, and other reduction in workforce initiatives executed earlier in the year. The lump-sum payments reduced our pension obligation by $215 million. The discount rate used for the remeasurement as of October 31, 2020 was 3.00% compared to the July 2020 remeasurement discount rate of 2.64%. Following these payments and the completion of the remeasurement of plan assets and liabilities, the Plan's funded status is 100% as of October 31, 2020. Please see Note 16, Subsequent Events, for additional information regarding the Plan.

Other Unfunded Benefit Plans
The Company also sponsors other supplemental retirement plans, primarily the Supplemental Retirement Program, the Benefit Restoration Plan and the Mirror Savings Plan, that were unfunded as of the Petition Date. Liabilities for those plans total $166 million and have been classified as Liabilities subject to compromise in the unaudited interim Consolidated Balance Sheets.
