10.   Income Taxes

​

The Company’s effective tax rate was 19.5% and 21.0% for the three months ended December 31, 2023 and 2022, respectively. The most significant items contributing to the difference between the statutory U.S. federal corporate tax rate of 21.0% and the Company’s effective tax rate for the three-month period ended December 31, 2023 were a tax benefit of $13.0 million related to income tax credits and incentives, tax expense of $11.3 million related to foreign residual income, a tax benefit of $6.9 million related to an audit settlement, tax expense of $4.4 million related to changes in valuation allowances, and tax expense of $4.2 million related to state income taxes. All these items, except for the audit settlement, are expected to have a continuing impact on the effective tax rate for the remainder of the fiscal year.

​

The most significant items contributing to the difference between the statutory U.S. federal corporate tax rate of 21.0% and the Company’s effective tax rate for the three-month period ended December 31, 2022 were a tax benefit of $8.6 million related to income tax credits and incentives and tax expense of $8.5 million related to foreign residual income.

​

During the first quarter of fiscal 2024, the Company settled its tax audit in Hong Kong for fiscal year 2011 through fiscal year 2021 and recorded a tax benefit of $6.9 million due primarily to changes in uncertain tax positions.

​

The Company is utilizing the annual effective tax rate method under ASC 740 to compute its interim tax provision. The Company’s effective tax rate fluctuates from quarter to quarter due to various factors including the change in the mix of global income and expenses, outcomes of administrative audits, changes in the assessment of valuation allowances due to management’s consideration of new positive or negative evidence during the quarter, and changes in enacted tax laws. The U.S.and many international legislative and regulatory bodies have proposed legislation that could significantly impact how our business activities are taxed. These proposed changes could have a material impact on the Company’s income tax expense and deferred tax balances.

​

The Company is currently under tax audit in several jurisdictions including the U.S. and believes the outcomes which are reasonably possible within the next twelve months, including lapses in statutes of limitations, could result in future adjustments in the liability for uncertain tax positions, but an estimate of the range of the reasonably possible outcomes cannot be made.

​

Generally, the Company does not provide for U.S. taxes or foreign withholding taxes on gross book-tax differences in its non-U.S. subsidiaries because such basis differences of approximately $1.3 billion are able to and intended to be reinvested indefinitely. If these basis differences were distributed, foreign tax credits could become available under current law to partially or

fully reduce the resulting U.S. income tax liability. There may also be additional U.S. or foreign income tax liability upon repatriation, although the calculation of such additional taxes is not practicable.
