Income Taxes

Our effective tax rate for the three months ended October 31, 2023 was 48.3%, which includes a net discrete tax expense of $2,049,000 primarily related to our decision to sell our Power Systems Technology product line in a taxable transaction and settlement of stock-based awards. Our effective tax rate for the three months ended October 31, 2022 was 5.2%, which includes a net discrete tax benefit of $111,000 primarily related to the deductible portion of CEO transition costs, partially offset by the settlement of stock-based awards.

Excluding discrete items, our effective tax rate for the three months ended October 31, 2023 and 2022 was 122.0% and 19.0%, respectively. The increase in our effective tax rate, excluding discretionary items, is primarily due to changes in expected product and geographic mix.

At October 31, 2023 and July 31, 2023, total unrecognized tax benefits were $9,258,000 and $9,166,000, respectively, including interest of $245,000 and $210,000, respectively. Unrecognized tax benefits result from income tax positions taken or expected to be taken on our income tax returns for which a tax benefit has not been recorded in our consolidated financial statements. We believe it is reasonably possible that the gross unrecognized tax benefits could decrease by as much as $610,000 in the next twelve months due to the expiration of a statute of limitations related to federal, state and foreign tax positions.

Our U.S. federal income tax returns for fiscal 2020 through 2022 are subject to potential future Internal Revenue Service ("IRS") audit. None of our state income tax returns prior to fiscal 2019 are subject to audit. Future tax assessments or settlements could have a material adverse effect on our consolidated results of operations and financial condition.
