The accumulated balances related to each component of Other Comprehensive Income/(Loss), net of taxes, were as follows: BMS sponsors defined benefit pension plans, defined contribution plans and termination indemnity plans for regular full-time employees. The principal defined benefit pension plan was the Bristol-Myers Squibb Retirement Income Plan (the “Plan”), which covered most U.S. employees. Future benefits related to service for the Plan were eliminated in 2009. BMS contributed at least the minimum amount required by ERISA. Plan benefits were based primarily on the participant’s years of credited service and final average compensation. In December 2018, BMS announced plans to fully terminate the Plan. Pension obligations related to the Plan were to be distributed through a combination of lump sum payments to eligible Plan participants who elected such payments and through the purchase of group annuity contracts from wholly owned insurance subsidiaries of Athene Holding Ltd. (“Athene”). In 2019, $1.3 billion was distributed to Plan participants who elected lump sum payments during the election window, and group annuity contracts were purchased from Athene for $2.6 billion for the remaining Plan participants for whom Athene irrevocably assumed the pension obligations. These transactions fully terminated the Plan and resulted in a $1.5 billion non-cash pre-tax pension settlement charge in 2019. BMS acquired Celgene on November 20, 2019. Certain of Celgene's international subsidiaries have both funded and unfunded defined benefit pension plans. We have recorded the fair value of the Celgene plans using assumptions and accounting policies consistent with those disclosed by BMS. Upon acquisition, the excess of projected benefit obligation over the plan assets was recognized as a liability and previously existing deferred actuarial gains and losses and unrecognized service costs or benefits were eliminated. 94 Note 17.
