Income Taxes Income Taxes
The Company accounts for income taxes in accordance with ASC 740. The provision for income taxes is attributable to U.S. federal, state, and foreign income taxes. The Company’s effective tax rate used for interim periods is based on an estimated annual effective tax rate including the tax effect of items required to be recorded discretely in the interim periods in which those items occur. The Company’s effective tax rate for the nine months ended December 31, 2022, increased significantly over the same period last year primarily due to a provision in the TCJA. Research and development expenditures incurred by the Company after March 31, 2022, must be capitalized and amortized ratably over five or fifteen years for tax purposes, depending on the location in which the research activities are conducted. The resulting capitalization of research and development expenditures impacts the calculation of the Company’s Global Intangible Low-Taxed Income (GILTI), which is treated as a period cost, beginning in the first quarter of fiscal 2023.

The Company's effective tax rate is different than the statutory rates in the U.S. due to foreign income taxed at different rates than the U.S., changes in uncertain tax benefit positions, changes to valuation allowances, generation of tax credits, and the impact of GILTI in the United States. In addition, the Company has numerous tax holidays it receives related to its Thailand manufacturing operations based on its investment in property, plant and equipment in Thailand. The Company's tax holiday periods in Thailand expire at various times in the future, however, the Company actively seeks to obtain new tax holidays. The material components of foreign income taxed at a rate lower than the U.S. are earnings accrued in Thailand, Malta, and Ireland.

The Company files U.S. federal, U.S. state, and foreign income tax returns.  For U.S. federal, and in general for U.S. state tax returns, the fiscal 2007 and later tax years remain open for examination by tax authorities.  For foreign tax returns, the Company is generally no longer subject to income tax examinations for years prior to fiscal 2007.
