Retirement Benefits [Abstract] |
Pension Plans | NOTE N — PENSION PLANS We sponsor several pension plans for our associates, including our principal plan (the “Retirement Plan”), which is a non-contributory defined benefit pension plan covering substantially all domestic non-union associates. Pension benefits are provided for certain domestic union associates through separate plans. Associates of our foreign subsidiaries receive pension coverage, to the extent deemed appropriate, through plans that are governed by local statutory requirements. The Retirement Plan provides benefits that are based upon years of service and average compensation with accrued benefits vesting after five years. Benefits for union associates are generally based upon years of service, or a combination of years of service and average compensation. Our pension funding policy considers contributions in an amount on an annual basis that can be deducted for federal income tax purposes, using a different actuarial cost method and different assumptions from those used for financial reporting. For the fiscal year ending May 31, 2026, we are required, based on minimum funding rules, to contribute approximately $6.1 million to our foreign plans. Required contributions, based on minimum funding rules, to the retirement plans in the United States for fiscal 2026 are immaterial. During the year, we will evaluate whether to make contributions in excess of the minimum required amounts. During fiscal 2025, we contributed $45.5 million to the pension plans in the United States which was in excess of the required immaterial contributions but serves to improve the funded status of the plans. Net periodic pension cost consisted of the following for the year ended May 31:

The fair value of the assets held by our pension plans has increased at May 31, 2025 since our previous measurement date at May 31, 2024, due to contributions and market returns. Total plan liabilities increased due to benefit accruals, an increase in interest cost caused by an increase in the discount rate, as well as a smaller actuarial gain than in the prior year. We have recorded an overfunded position for the net status of our pension plans. We expect pension expense in fiscal 2026 to be lower than our fiscal 2025 expense level due to an increase in discount rates, an increase in the market value of assets, an increase in expected return on plan assets and a reduction in the amortization of the net actuarial loss to be recognized. Any future declines in the value of our pension plan assets or increases in our plan liabilities could require us to decrease our recorded asset for the net funded status of our pension plans and could also require accelerated and higher cash contributions to our pension plans. Amounts recognized in the Consolidated Balance Sheets for the years ended May 31, 2025 and 2024 are as follows:

In measuring the projected benefit obligation and net periodic pension cost for our plans, we utilize actuarial valuations. These valuations include specific information pertaining to individual plan participants, such as salary, age and years of service, along with certain assumptions. The most significant assumptions applied include discount rates, expected return on plan assets and rate of compensation increases. We evaluate these assumptions, at a minimum, on an annual basis, and make required changes, as applicable. In developing our expected long-term rate of return on pension plan assets, we consider the current and expected target asset allocations of the pension portfolio, as well as historical returns and future expectations for returns on various categories of plan assets. Expected return on assets is determined by using the weighted-average return on asset classes based on expected return for the target asset allocations of the principal asset categories held by each plan. In determining expected return, we consider both historical performance and an estimate of future long-term rates of return. Actual experience is used to develop the assumption for compensation increases. The following weighted-average assumptions were used to determine our year-end benefit obligations and net periodic pension cost under the plans:
|  | U.S. Plans |  | Non-U.S. Plans |  |
Year-End Benefit Obligations |  | 2025 |  | 2024 |  | 2025 |  | 2024

The primary objective for the investments of the Retirement Plan is to provide for long-term growth of capital without undue exposure to risk. This objective is accomplished by utilizing a diversified portfolio strategy of equities, fixed-income securities and cash equivalents in a mix that is conducive to participation in a rising market, while allowing for adequate protection in a falling market. Our Investment Committee oversees the investment allocation process, which includes the selection and evaluation of investment managers, the determination of investment objectives and risk guidelines, and the monitoring of actual investment performance. In order to manage investment risk properly, Plan policy prohibits short selling, securities lending, financial futures, options and other specialized investments, except for certain alternative investments specifically approved by the Investment Committee. The Investment Committee reviews, on a quarterly basis, reports of actual Plan investment performance provided by independent third parties, in addition to its review of the Plan investment policy on an annual basis. The investment objectives are similar for our plans outside of the United States, subject to local regulations. The goals of the investment strategy for pension assets include: the total return of the funds shall, over an extended period of time, surpass an index composed of the MSCI World Stock Index (equity), the Barclays Long-Term Government/Credit Index (fixed income), and 30-day Treasury Bills (cash), weighted appropriately to match the asset allocation of the plans. The equity portion of the funds shall surpass the MSCI World Stock Index over a full market cycle, while the fixed-income portion shall surpass Barclays Long-Term Government/Credit Index over a full market cycle. The purpose of the fixed-income fund is to reduce the overall volatility of the plan liabilities and provide a hedge against interest rate fluctuations. Therefore, the primary objective of the fixed-income portion is to match the Barclays Long-Term Government/Credit Index. We expect to pay the following estimated pension benefit payments in the next five years (in millions): $75.3 in 2026, $77.5 in 2027, $81.5 in 2028, $89.2 in 2029 and $89.1 in 2030. In the five years thereafter (2031-2035), we expect to pay $448.3 million. In addition to the defined benefit pension plans discussed above, we also sponsor associate savings plans under Section 401(k) of the Internal Revenue Code, which cover most of our associates in the United States. We record expense for defined contribution plans for any employer-matching contributions made in conjunction with services rendered by associates. The majority of our plans provide for matching contributions made in conjunction with services rendered by associates. Matching contributions are invested in the same manner that the participants invest their own contributions. Matching contributions charged to income wer e $31.3 million, $29.8 million and $27.6 million for the years ending May 31, 2025, 2024 and 2023, respectively.
