       Plan assets are generally invested with the long-term objective of producing earnings to adequately cover expected benefit obligations. The expected rates of return on plan assets reflect subjective assessments of expected long-term investment returns. Generally, past investment returns are not given significant consideration when establishing assumptions for expected long-term rates of return on plan assets. Actual experience will differ from the assumed rates of return.

       Our subsidiaries may also sponsor defined contribution retirement plans, such as 401(k) or profit-sharing plans. Employee contributions are subject to regulatory limitations and specific plan provisions. Several of these plans provide for employer matching contributions as specified in the plans and may provide for additional discretionary employer contributions. Our defined contribution plan expense was approximately $1.3 billion in 2024, $1.1 billion in 2023 and $0.8 billion in 2022.
