Segment Reporting [Abstract]
Segment Reporting Policy	Mylan reports segment information on a geographic basis. This approach reflects the company’s focus on bringing its broad and diversified portfolio of generic, branded generic, brand-name and over-the-counter products to people in markets everywhere. Our North America segment comprises our operations in the U.S. and Canada. Our Europe segment comprises our operations in more than 35 countries, including France, Italy, Germany, the U.K. and Spain. Our Rest of World segment reflects our operations in more than 120 countries, including Japan, Australia, China, Brazil, Russia, India, South Africa and certain markets in the Middle East and Southeast Asia. The Company’s chief operating decision maker is the Chief Executive Officer, who evaluates the performance of its segments based on total revenues and segment profitability. Segment profitability represents segment gross profit less direct R&D and direct SG&A. Certain general and administrative and R&D expenses not allocated to the segments, including certain special items, net charges for litigation settlements and other contingencies, amortization of intangible assets, impairment charges and other expenses not directly attributable to the segments are reported separately or outside of segment profitability. Items below the earnings from operations line on the Company’s Condensed Consolidated Statements of Operations are not presented by segment, since they are excluded from the measure of segment profitability. The Company has revised segment profitability for Rest of World to conform with the current presentation by reclassifying approximately $78.2 million of net gains to litigation settlements and other contingencies for the nine months ended September 30, 2017. The Company does not report depreciation expense, total assets and capital expenditures by segment, as such information is not used by the chief operating decision maker. The accounting policies of the segments are the same as those described in Note 2 Revenue Recognition and Accounts Receivable above and the “Summary of Significant Accounting Policies” included in the 2017 Form 10-K. Intersegment revenues are accounted for at current market values and are eliminated at the consolidated level.
