Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The income tax benefit for the three and nine months ended July 1, 2017 included certain discrete benefits of $2,801 recognized during the three months ended July 1, 2017 which consisted of additional U.S. tax benefits for prior fiscal years associated with domestic manufacturing, deductible PCB acquisition-related expenses and U.S. R&D tax credit. Excluding the impact of these discrete benefits, the effective tax rate for the three and nine months ended July 1, 2017 declined compared to the prior year periods primarily due to lower income before taxes and a more favorable geographic mix of earnings. The income tax provision for the three months ended July 2, 2016 included a one-time tax cost of $577 associated with non-deductible PCB acquisition-related expenses. The income tax provision for the nine months ended July 2, 2016 included a $2,283 discrete benefit for retroactive reinstatement of the U.S. R&D tax credit as well as a one-time tax cost of $577 associated with non-deductible PCB acquisition-related expenses. As of July 1, 2017, the liability for unrecognized tax benefits was $6,475, of which $3,700 would favorably affect our effective tax rate, if recognized. As of October 1, 2016, the liability for unrecognized tax benefits was $6,232, of which $3,429 would favorably affect our effective tax rate, if recognized. As of July 1, 2017, we do not expect significant changes in the amount of unrecognized tax benefits during the next twelve months.
