Income Tax [Abstract]
Income Taxes	INCOME TAXES Our effective tax rates were (10.5)% and 7.9% in the three months 2018 and 2017. The decrease in the effective tax rate was primarily due to adjustments related to the Tax Cuts and Jobs Act (the Act) of 2017. Our effective tax rates were 12.6% and 10.3% in the nine months 2018 and 2017. The increase in the effective income tax rate was primarily due to adjustments related to the Act and restructuring-related activities to integrate recent acquisitions. In December 2017 we recorded a provisional transition tax charge and a change in deferred tax accounts associated with the Act. Subsequent to the Act being signed into legislation, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 to provide guidance that allows provisional amounts associated with the Act to be updated during a measurement period ending December 22, 2018. Our accounting for the impact of the Act is not complete and the final impact of the Act may differ from our estimates due to changes in interpretation of the Act, additional legislative action, or guidance issued by tax authorities or regulatory bodies.

INCOME TAXES

Our effective tax rates were (10.5)% and 7.9% in the three months 2018 and 2017. The decrease in the effective tax rate was primarily due to adjustments related to the Tax Cuts and Jobs Act (the Act) of 2017.

Our effective tax rates were 12.6% and 10.3% in the nine months 2018 and 2017. The increase in the effective income tax rate was primarily due to adjustments related to the Act and restructuring-related activities to integrate recent acquisitions.

In December 2017 we recorded a provisional transition tax charge and a change in deferred tax accounts associated with the Act. Subsequent to the Act being signed into legislation, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 to provide guidance that allows provisional amounts associated with the Act to be updated during a measurement period ending December 22, 2018. Our accounting for the impact of the Act is not complete and the final impact of the Act may differ from our estimates due to changes in interpretation of the Act, additional legislative action, or guidance issued by tax authorities or regulatory bodies.
