We record the service cost component of net periodic benefit cost (benefit) in the same line item as other employee compensation costs. The non-service components of net periodic benefit cost (benefit), such as interest cost, expected return on assets, amortization of prior service cost, and actuarial gains or losses, are recorded within “other income (expense), net” in the condensed consolidated statement of operations.
We did not contribute to our U.S. defined benefit plans or U.S. post-retirement benefit plan during the three and nine months ended July 31, 2026 and 2025. We contributed $2 million and $3 million to our non-U.S. defined benefit plans during
the three months ended July 31, 2026 and 2025, respectively, and $7 million and $8 million during the nine months ended July 31, 2026 and 2025, respectively.
For the remainder of 2026, we do not expect to contribute to our U.S. defined benefit plans and U.S. post-retirement benefit plan, and we expect to contribute $3 million to our non-U.S. defined benefit plans. The amounts we contribute depend on, among other factors, legal requirements, underlying asset returns, the plan’s funded status, the anticipated tax deductibility of the contributions, local practices, employee retirements, market conditions, interest rates, and other factors.
