Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Since March 2015, over 50 putative class action complaints were filed by contact lens consumers alleging that contact lens manufacturers, in conjunction with their respective Unilateral Pricing Policy (UPP), conspired to reach agreements between each other and certain distributors and retailers regarding the prices at which certain contact lenses could be sold to consumers. The plaintiffs are seeking damages against CooperVision, Inc., other contact lens manufacturers, distributors and retailers, in various courts around the United States. In June 2015, all of the class action cases were consolidated and transferred to the United States District Court for the Middle District of Florida. In August 2017, CooperVision entered into a settlement agreement with the plaintiffs, without any admission of liability, to settle all claims against CooperVision. In July 2018, the Court approved the plaintiffs’ motion for preliminary approval of the settlement, and the Company paid the $3.0 million settlement amount into an escrow account. The settlement remains subject to final Court approval at a future hearing to be set by the Court. The Company is involved in various lawsuits, claims and other legal matters from time to time that arise in the ordinary course of conducting business, including matters involving our products, intellectual property, supplier relationships, distributors, competitor relationships, employees and other matters. The Company does not believe that the ultimate resolution of these proceedings or claims pending against it could have a material adverse effect on its financial condition or results of operations. At each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under ASC 450, Contingencies.

Income Taxes, during fiscal 2017, the U.K. Tax Authorities began an inquiry regarding our application of DPT in fiscal 2015.

On December 20, 2017, the U.K. Tax Authorities issued a DPT charging notice of approximately GBP 31.0 million with respect to the transfer out of the United Kingdom of certain intellectual property rights in connection with the 2014 acquisition of Sauflon Pharmaceutical Ltd. Although taxes were paid on the transfer, the U.K. Tax Authorities are challenging the value assigned to such property. We intend to contest the charging notice vigorously.
