Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's effective tax rate in the first half of 2018 was 19.6% compared with 21.1% in the first half of 2017 and 69.6% for the full year 2017. The effective tax rate in 2017 was impacted by the U.S. government's enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "Act"). Excluding the impact of a one-time $99,214 of discrete tax expense related to the Act, partially offset by a benefit of $2,514 on the prior year repatriation, the effective tax rate would have been 20.2% for the full year 2017. The decrease in the first half of 2018 effective tax rate from the full year 2017 adjusted rate is primarily due to the application of the provisions within recent guidance issued by the U.S. Department of Treasury and the resulting tax impact (see discussion below), an adjustment to certain international valuation reserves and an increase in the projected change in the mix of earnings attributable to lower-taxing jurisdictions. The decrease is partially offset by a new provision within the Act that is designed to tax global intangible low-taxed income ("GILTI"), the absence of the adjustment of the Swiss valuation reserves, the absence of the settlement of tax audits and closure of tax years for various tax jurisdictions, the expiration of certain tax holidays and the decrease in the excess tax benefit on stock awards. The U.S. Department of Treasury released Notice 2018-26 in April 2018 (the "Notice"). The Notice provides additional guidance to assist companies in calculating the one-time Transition Tax. Various states have also issued guidance related to calculating the tax impacts of the Act, as well as clarifications describing how States will tax income arising from the application of provisions within the Act. As a result of the recent guidance, the Company has reduced the tax expense related to the impact of the Act recorded as of December 31, 2017 by $1,522 in the three month period ended June 30, 2018. Additional guidance related to Transition Tax, both from a federal and state standpoint, is anticipated by the end of 2018. The Company has determined that foreign earnings for the period beginning January 1, 2018 will be indefinitely reinvested. Accordingly, a deferred tax liability has not been recorded for the excess of the tax basis over the financial statement (book) basis arising since January 1, 2018. For the period ended December 31, 2017, the Company recorded a deferred tax liability of $6,932 on the portion of earnings it expects to repatriate. The Company continues to analyze its position in regards to the excess of the tax basis over the financial statement (book) basis arising for the period prior to January 1, 2018. As of June 30, 2018, the Company has not completed the accounting related to the income tax effects for certain sections of the Act and therefore the amount remains provisional. The Aerospace and Industrial segments were previously awarded international tax holidays. All significant tax holidays for which the Company received benefit have expired.
