Retirement Plans and Postretirement Medical Benefits | Retirement Plans and Postretirement Medical Benefits We provide certain retirement benefits to our U.S. employees hired prior to January 1, 2005 and to eligible employees outside the U.S. under various defined benefit retirement plans. Benefit accruals under most of our significant defined benefit plans have been frozen. We also provide certain employer subsidized health care and employer provided life insurance benefits in the U.S. and Canada to eligible retirees and their dependents. Employees hired before January 1, 2005 in the U.S. and April 1, 2005 in Canada become eligible for retiree medical benefits after reaching age 55 and with the completion of the required service period. The cost of these benefits is recognized over the period the employee provides credited service to the company.

The discount rate for our U.S. pension and postretirement medical benefit plans is determined by matching the expected cash flows associated with our benefit obligations to a pool of corporate long-term, high-quality fixed income debt instruments available as of the measurement date. The discount rate for our largest foreign plan, the U.K. Qualified Pension Plan (the U.K. Plan), is determined by using a model that discounts each year's estimated benefit payments by an applicable spot rate derived from a yield curve created from a large number of high quality corporate bonds. For our other smaller foreign pension plans, the discount rate is selected based on high-quality fixed income indices available in the country in which the plan is domiciled. The expected return on plan assets is based on historical and expected rates of return for current and planned asset classes in the plans' investment portfolio after analyzing historical experience and future expectations of the returns and volatility of the various asset classes. The overall expected rate of return for the portfolio is based on the target asset allocation of our global pension plans, adjusted for historical and expected experience of active portfolio management results, when compared to the benchmark returns. During 2020 , we estimate making contributions of $9 million to our U.S. pension plans and $10 million to our foreign pension plans. Investment Strategy and Asset Allocation - U.S. Pension Plans The investment strategy of our U.S. pension plans is to maximize returns within reasonable and prudent levels of risk, to achieve and maintain full funding of the accumulated benefit obligation and the actuarial liabilities and to earn an expected rate of return. Pension plan assets are invested in accordance with our strategic asset allocation policy to achieve these objectives. Pension plan assets are exposed to various risks, such as interest rate, market and credit risks. Investments are diversified across asset classes and within each class to reduce the risk of large losses and are periodically rebalanced. Derivatives, such as swaps, options, forwards and futures contracts may be used for market exposure, to alter risk/return characteristics and to manage foreign currency exposure. We do not have any significant concentrations of credit risk within the plan assets. Investment objectives and investment managers are reviewed periodically. Target and actual asset allocations for the U.S. pension plans were as follows: Target allocation Percent of Plan Assets at December 31, 2020 2019 2018 Asset category Equities 30 % 30 % 26 % Fixed income 63 % 63 % 64 % Real estate 5 % 5 % 7 % Private equity 2 % 2 % 3 % Total 100 % 100 % 100 % Investment Strategy and Asset Allocation - Foreign Pension Plans Our foreign pension plan assets are managed by outside investment managers and monitored regularly by local trustees and our corporate personnel. Investment strategies vary by country and plan, with each strategy tailored to achieve the expected rate of return within an appropriate risk level, depending upon the liability profile of plan participants, local funding requirements, investment markets and restrictions. The U.K. Plan comprises 77% of the total foreign pension plan assets. The U.K. pension plan's investment strategy is to maximize returns within reasonable and prudent levels of risk, to achieve and maintain full funding of the accumulated benefit obligation and the actuarial liabilities and to earn an expected rate of return. Plan assets are invested in accordance with our strategic asset allocation policy to achieve these objectives. Pension plan assets are exposed to various risks, such as interest rate, market and credit risks. Investments are diversified across asset classes and within each class to minimize the risk of large losses and are periodically rebalanced. Derivatives, such as swaps, options, forwards and futures contracts may be used for market exposure, to alter risk/return characteristics and to manage currency exposure. We do not have any significant concentrations of credit risk within the plan assets. Investment objectives and investment managers are reviewed periodically. Target and actual asset allocations for the U.K. Plan were as follows: Target Allocation Percent of Plan Assets at December 31, 2020 2019 2018 Asset category Equities 30 % 35 % 38 % Fixed income 50 % 46 % 41 % Real estate 10 % 9 % 10 % Diversified growth 10 % 9 % 10 % Cash — % 1 % 1 % Total 100 % 100 % 100 % The target asset allocation used to manage the investment portfolios is based on the broad asset categories shown above. The plan asset categories presented in the fair value hierarchy are subsets of the broad asset categories. The fair value of the U.K. plan assets was $516 million and $426 million at December 31, 2019 and 2018 , respectively, and the expected long-term weighted average rate of return on these plan assets was 6.25% in both 2019 and 2018 .

Money market funds are principally used for overnight deposits. • Equity Securities: include U.S. and foreign stocks, American Depository Receipts, preferred stock and commingled funds. There are no shares of our common stock included in the plan assets of our pension plans. • Commingled Fixed Income Securities: mutual funds that invest in fixed income securities of the U.S. government and its agencies, corporate debt, mortgage-backed securities and asset-backed securities. Fair value is based on the market value of the underlying investments owned by each fund, minus its liabilities, divided by the number of shares outstanding as reported by the fund manager. • Government and Related Securities: include treasury notes and bonds, foreign government issues, U.S. government sponsored agency debt and commingled funds. Municipal debt securities include general obligation securities and revenue-backed securities. Fair value is based on benchmarking model derived prices to quoted market prices and trade data for identical comparable securities. • Corporate Debt Securities : comprised of both investment grade debt and high-yield debt. Fair value is determined using recently executed transactions, market price quotations where observable, or bond spreads. • Mortgage-Backed Securities / Asset-Backed Securities : mortgage-backed securities (MBS) are comprised of agency-backed MBS, non-agency MBS, collateralized mortgage obligations, commercial MBS and commingled funds. Asset-backed securities (ABS) are primarily comprised of credit card receivables, auto loan receivables, student loan receivables and Small Business Administration loans. These securities are valued based on external pricing indices, external price/spread data or broker quotes. • Private Equity : comprised of units in fund-of-funds investment vehicles. Fund-of-funds consist of various private equity investments and are used in an effort to gain greater diversification. Investments are valued in accordance with the most appropriate valuation techniques. • Real Estate: include units in open-ended commingled real estate funds. Investments are valued in accordance with the most appropriate valuation techniques. • Diversified Growth Funds: comprised of units in commingled diversified growth funds. Investments are valued based on the net asset value (NAV) per unit as reported by the fund manager. • Securities Lending Fund: represents a commingled fund through our custodian's securities lending program. The U.S. pension plan lends securities that are held within the plan to other banks and/or brokers, and receives collateral, typically cash. This collateral is invested in a short-term fixed income securities commingled fund. This amount invested in the fund is offset by a corresponding liability reflected in the U.S. pension plan's net assets available for benefits.
