INCOME TAXES INCOME TAXES
For the three and six months ended April 30, 2025, our income tax expense was $45 million with an effective tax rate of 17.3 percent and $94 million with an effective tax rate of 15.0 percent, respectively. For the three and six months ended April 30, 2025, there were no significant discrete items.

For the three and six months ended April 30, 2024, our income tax expense was $66 million with an effective tax rate of 17.6 percent and $121 million with an effective tax rate of 15.6 percent, respectively. For the three and six months ended April 30, 2024, our effective tax rate and the resulting provision for income taxes were impacted by the tax expense of $12 million related to the settlement of an audit in Singapore.

In the U.S., tax years remain open back to the year 2021 for federal income tax purposes and 2020 for significant states. In other major jurisdictions where we conduct business, the tax years generally remain open back to the year 2014.

With these jurisdictions and the U.S., it is reasonably possible that some tax audits may be completed over the next twelve months. However, management is not able to provide a reasonably reliable estimate of the timing of any other future tax payments or change in unrecognized tax benefits, if any.
