Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes VPG calculates the tax provision for interim periods using an estimated annual effective tax rate methodology based on projected full-year pre-tax earnings among the taxing jurisdictions in which we operate with adjustments for discrete items. The effective tax rate for the fiscal quarter ended March 28, 2020 was 32.3% compared to 27.2% for the fiscal quarter ended March 30, 2019. The tax rate in the current fiscal quarter is higher than the prior year fiscal quarter primarily due to changes in the mix of worldwide income. The Company and its subsidiaries are subject to income taxes imposed by the U.S., various states, and the foreign jurisdictions in which we operate. Each jurisdiction establishes rules that set forth the years which are subject to examination by its tax authorities. While the Company believes the tax positions taken on its tax returns for each jurisdiction are supportable, they may still be challenged by the jurisdiction's tax authorities. In anticipation of such challenges, the Company has established reserves for tax-related uncertainties. These liabilities are based on the Company’s best estimate of the potential tax exposures in each respective jurisdiction. It may take a number of years for a final tax liability in a jurisdiction to be determined, particularly in the event of an audit. If an uncertain matter is determined favorably, there could be a reduction in the Company’s tax expense. An unfavorable determination could increase tax expense and could require a cash payment, including interest and penalties.
