Retirement Benefits [Abstract]  
PENSION, HEALTH CARE AND OTHER POSTRETIREMENT BENEFITS PENSION, HEALTH CARE AND OTHER POSTRETIREMENT BENEFITS
The Company provides pension benefits to substantially all full-time employees through primarily noncontributory defined contribution or defined benefit plans and certain health care and life insurance benefits to domestic active employees and eligible retirees. In accordance with the Retirement Benefits Topic of the ASC, the Company recognizes an asset for overfunded defined benefit pension or other postretirement benefit plans and a liability for unfunded or underfunded plans. In addition, actuarial gains and losses and prior service costs of such plans are recorded in AOCI. The amounts recorded in AOCI will continue to be modified as actuarial assumptions and service costs change, and all such amounts will be amortized to expense over a period of years through the net pension cost (credit) and net periodic benefit cost (credit).
Health Care Plans
The Company provides certain domestic health care plans that are contributory and contain cost-sharing features such as deductibles and coinsurance. There were 29,016, 27,782 and 27,030 active employees entitled to receive benefits under these plans at December 31, 2021, 2020 and 2019, respectively. The cost of these benefits for active employees, which includes claims incurred but not reported, amounted to $336.0 million, $298.8 million and $301.6 million for 2021, 2020 and 2019, respectively.
Defined Contribution Pension Plans
The Company’s annual contribution for its domestic defined contribution pension plan was $85.3 million, $77.0 million and $72.7 million for 2021, 2020 and 2019, respectively. The contribution percentage ranges from two percent to seven percent of compensation for covered employees based on an age and service formula. Assets in employee accounts of the domestic defined contribution pension plan are invested in various investment funds as directed by the participants. These investment funds did not own a significant number of shares of the Company’s common stock for any year presented.
The Company’s annual contributions for its foreign defined contribution pension plans, which are based on various percentages of compensation for covered employees up to certain limits, were $17.9 million, $22.5 million and $24.5 million for 2021, 2020 and 2019, respectively. Assets in employee accounts of the foreign defined contribution pension plans are invested in various investment funds. These investment funds did not own a significant number of shares of the Company’s common stock for any year presented.
Defined Benefit Pension Plans
In 2018, the Company’s domestic defined benefit pension plan was split into two separate overfunded plans: one that will continue to operate, and one that was frozen and subsequently terminated during 2018 (Terminated Plan). Active participants in the Terminated Plan were moved to the Company’s domestic defined contribution plan (Qualified Replacement Plan). The Company settled the liabilities of the Terminated Plan through a combination of (i) lump sum payments to eligible participants who elected to receive them and (ii) the purchase of annuity contracts for participants who either did not elect lump sums or were already receiving benefit payments. The lump sum payments were paid in December 2018. During the first quarter of 2019, the Company purchased annuity contracts to settle the remaining liabilities of the Terminated Plan. The annuity contract purchase resulted in a settlement charge of $32.4 million in the first quarter of 2019. The remaining surplus of the Terminated Plan is being used, as prescribed in the applicable regulations, to fund Company contributions to the Qualified Replacement Plan. During 2019, the Company transferred the remaining surplus of $242.2 million to a suspense account held within a trust for the Qualified Replacement Plan. This amount included $131.8 million of Company common stock (900,000 shares). The shares are treated as treasury stock in accordance with ASC 715. See Note 11. The remaining surplus consists of investment funds held at fair value. See Note 16.
At December 31, 2021, the domestic defined benefit pension plan was overfunded, with a projected benefit obligation of $120.8 million, fair value of plan assets of $155.2 million and excess plan assets of $34.4 million. The plan was funded in accordance with all applicable regulations at December 31, 2021.
The Company has thirty-three foreign defined benefit pension plans. At December 31, 2021, twenty-seven of the Company’s foreign defined benefit pension plans were unfunded or underfunded, with combined accumulated benefit obligations, projected benefit obligations, fair values of net assets and deficiencies of plan assets of $95.2 million, $108.5 million, $29.5 million and $79.0 million, respectively.
The Company expects to make the following benefit payments for all domestic and foreign defined benefit pension plans: $15.2 million in 2022; $14.8 million in 2023; $16.1 million in 2024; $16.9 million in 2025; $23.1 million in 2026; and $105.4 million in 2027 through 2031. The Company expects to contribute $5.8 million to the foreign plans in 2022.
The estimated net actuarial losses and prior service credits for the defined benefit pension plans that are expected to be amortized from AOCI into the net pension costs in 2022 are $0.3 million and $(0.2) million, respectively.
The following table summarizes the components of the net pension costs and AOCI related to the defined benefit pension plans:

The Company employs a total return investment approach for the domestic and foreign defined benefit pension plan assets. A mix of equities and fixed income investments are used to maximize the long-term return of assets for a prudent level of risk. In determining the expected long-term rate of return on defined benefit pension plan assets, management considers the historical rates of return, the nature of investments and an expectation of future investment strategies. The target allocations for plan assets are 35% – 65% equity securities, 35% – 55% fixed income securities and 0% – 10% other (including alternative investments and cash).
The following tables summarize the fair value of the defined benefit pension plan assets at December 31, 2021, 2020 and 2019. The presentation is in accordance with the Retirement Benefits Topic of the ASC.
