Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill As part of our on-going assessment of goodwill at September 30, 2017, we noted that third quarter 2017 sales, profitability and cash flow of our Mexico reporting unit (within the Latin America segment) significantly underperformed in comparison to the forecast, and expectations for the fourth quarter of 2017 were lowered as well. These factors, as well as continuing competitive pressures, long term weakness of the Mexican peso relative to the U.S. dollar, and an increase in the discount rate of 70 basis points since December 31, 2016 to September 30, 2017, all contributed to increased pressure on the outlook of the reporting unit. As a result, we determined a triggering event had occurred for our Mexico reporting unit. Accordingly, an interim impairment test was performed as of September 30, 2017, indicating that the carrying value of the Mexico reporting unit exceeded its fair value, and in accordance with the early adoption of ASU 2017-04, we recorded a non-cash impairment charge of $79.7 million during the third quarter of 2017. After the impairment charge at September 31, 2017, the remaining net goodwill balance was $46.0 million in our Mexico reporting unit. There has been no goodwill impairment charge in 2018, and there were no goodwill impairment indicators that led to a conclusion that an impairment was more likely than not as of September 30, 2018. For a complete discussion on how we measure each reporting unit's fair value, please refer to note 4, "Purchased Intangible Assets and Goodwill," in our 2017 Annual Report on Form 10-K.
