Private equity's investment objective is to generate returns on capital from a diversified portfolio of primary fund investments, secondaries and co-investments. The plan's unfunded commitments to private equity were approximately $180 million at December 31, 2024. However, the managers also expect to make significant cash flow distributions in 2025 and 2026.

(k)Real Estate investments are open-end real estate funds that invest in a portfolio of real properties that are broadly diversified by geography and property type. The real estate asset class is expected to produce returns from income and capital appreciation. Real estate also provides a hedge against inflation.

(l)Hedge Funds are structured as a custom fund of one and can invest in external hedge fund managers that pursue a wide array of strategies including event driven, fundamental long/short, relative value, directional trading, and direct sourcing.

The net assets held in the 401(h) account are calculated based on a pro-rata percentage allocation of the net assets in the pension plan. The related obligations for health benefits are not included in the pension plan’s obligations and are included in the Companies’ other postretirement benefit obligation. See Note F. (n)Pending activities include security purchases and sales that have not settled, interest and dividends that have not been received and reflects adjustments for available estimates at year end.
