Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On December 22, 2017, the President of the U.S. signed into law the Tax Cuts and Jobs Act (H.R. 1) (the “Act”), which is expected to have a materially favorable impact to the Company's net income, cash flows, and diluted earnings per share in future periods. The Act reduces the federal corporate tax rate from 35% to 21% effective January 1, 2018. Additionally, the Company will be required to evaluate the Act's impact on certain discrete items, including the remeasurement of the Company's net deferred tax liabilities and the taxation of the Company's accumulated unremitted foreign earnings. The Company is currently reviewing the components of the Act and evaluating its impact on its financial position, operations, and future cash flows.
