Retirement Benefits [Abstract]  
Employee Benefit and Retirement Plans Employee Benefit and Retirement Plans
The Company and its subsidiaries have noncontributory pension, profit sharing and contributory 401(k) plans covering substantially all of their international and domestic employees. Plan benefits are generally based on years of service and/or compensation. The Company’s funding policy is to contribute not less than the minimum amounts required by the Employee Retirement Income Security Act of 1974, as amended, the Internal Revenue Code of 1986, as amended, or foreign statutes to ensure that plan assets will be adequate to provide retirement benefits.
The amount of AOCL expected to be recognized in pension and postretirement benefit expense for 2020 is $20.3 million and is substantially comprised of net unrecognized actuarial losses.

The Company has a Supplemental Executive Retirement Plan (“SERP”), which is a nonqualified defined benefit and defined contribution plan pursuant to which the Company will pay supplemental benefits to certain key employees upon retirement based upon the employees’ years of service and compensation. The SERP is primarily funded through a trust agreement with a trustee that owned life insurance policies on both active and former key employees with aggregate net death benefits of $311 million. At December 31, 2019 and 2018, the life insurance contracts were accounted for using the investment method and had a cash surrender value of $134 million and $135 million, respectively, and are included in other assets in the Consolidated Balance Sheets. All premiums paid and proceeds received associated with the life insurance policies are included in accrued liabilities and other in the Consolidated Statements of Cash Flows. The projected benefit obligation was $118 million and $115 million at December 31, 2019 and 2018, respectively. The SERP liabilities are included in the pension table below; however, the value of the Company’s investments in the life insurance contracts, cash and mutual funds are excluded from the table, as they do not qualify as plan assets.

The Company’s matching contributions to the contributory 401(k) plans were $31.6 million, $24.8 million and $30.2 million for 2019, 2018 and 2017, respectively.

(1)
The accumulated benefit obligation for all defined benefit pension plans was $2.1 billion and $1.9 billion at December 31, 2019 and 2018, respectively.
There are no plan assets associated with the Company’s postretirement benefit plans.
The current healthcare cost trend rate gradually declines through 2038 to the ultimate trend rate and remains level thereafter. A one percentage point change in assumed healthcare cost trend rate would not have a material effect on the postretirement benefit obligation or the service and interest cost components of postretirement benefit costs.

Plan Assets
The Company employs a total return investment approach for its pension plans whereby a mix of equities and fixed income investments are used to maximize the long-term return of pension plan assets. The intent of this strategy is to minimize plan expenses by outperforming plan liabilities over the long run. Risk tolerance is established through careful consideration of plan liabilities, plan funded status, and the Company’s financial condition. The domestic investment portfolios contain a diversified blend of equity and fixed-income investments. The domestic equity investments are diversified across geography and market capitalization through investments in U.S. large-capitalization stocks, U.S. small-capitalization stocks and international securities. The domestic fixed income investments are primarily comprised of investment-grade and high-yield securities through investments in corporate and government bonds, government agencies and asset-backed securities. The Level 1 investments are primarily based upon quoted market prices. The domestic Level 3 investments are primarily comprised of insurance contracts valued at contract value. The investments excluded from the fair value hierarchy are NAV-based hedge fund investments that generally have a redemption frequency of 90 days or less, with various redemption notice periods that are generally less than a month. The notice periods for certain investments may vary based on the size of the redemption. The international Level 2 investments are primarily comprised of insurance contracts whose fair values are estimated based on the future cash flows to be received under the contracts discounted to the present using a discount rate that approximates the discount rate used to measure the associated pension plan liabilities. The international Level 3 investments are primarily comprised of insurance contracts valued at contract value. Investment risk is measured and monitored on an ongoing basis through annual liability measurements, periodic asset/liability studies and quarterly investment portfolio reviews.
The expected long-term rate of return for plan assets is based upon many factors, including expected asset allocations, historical asset returns, current and expected future market conditions, risk and active management premiums. The expected long-term rate of return is adjusted when there are fundamental changes in expected returns on the Company’s defined benefit pension plan’s investments. The target asset allocations for the Company’s domestic pension plans may vary by plan, based in part due to plan demographics, funded status and liability duration. In general, the Company’s target asset allocations are as follows: equities approximately 20% to 40%; fixed income approximately 40% to 60%; and cash, alternative investments and other, approximately 10% to 30% at December 31, 2019. Actual asset allocations may vary from the targeted allocations for various reasons, including market conditions and the timing of transactions. The Company maintains numerous international defined benefit pension plans. The asset allocations for the international investment may vary by plan and jurisdiction and are primarily based upon the plan structure and plan participant profile.
The composition of domestic pension plan assets at December 31, 2019 and 2018 is as follows (in millions):
