Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General The accompanying unaudited interim consolidated financial statements and related notes should be read in conjunction with the audited Consolidated Financial Statements of the Cooper Companies, Inc and its subsidiaries (the Company) and related notes as contained in the Company’s Annual Report on Form 10-K for the fiscal year ended October 31, 2017. The unaudited interim financial statements include all adjustments (consisting only of normal recurring adjustments) and accruals necessary in the judgment of management for a fair statement of the results for the periods presented. Readers should not assume that the results reported here either indicate or guarantee future performance. Accounting Pronouncements Issued Not Yet Adopted In March 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The ASU requires an entity to disaggregate the service cost component from the other components of net benefit cost. The service cost component is presented in the same line items as other compensation costs arising from services rendered by the pertinent employees during the period and the other components of net benefit costs are presented separately as other income/expense below income from operations. ASU 2017-07 is effective for the Company in our fiscal 2019 and is not expected to have a significant impact on the Company's consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. ASU 2016-18 provides guidance on the classification and presentation of changes in restricted cash and cash equivalents in the statement of cash flows. ASU 2016-18 will be effective for the Company in fiscal 2019 and is not expected to have a significant impact on the Company's Consolidated Statements of Cash Flows. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which requires entities to recognize the income tax consequences on an intra-entity transfer of an asset other than inventory when the transfer occurs. The ASU changes the timing of the recognition of the income tax consequences of non-inventory transfers which under current guidance defers the income tax consequences until the asset is sold to an outside party or otherwise recognized. The guidance for the amendments of ASU 2016-16 requires companies to apply a modified retrospective approach with a cumulative catch-up adjustment to opening retained earnings in the period of adoption. We are currently evaluating the impact of ASU 2016-16 which is effective for the Company in our fiscal year and interim periods beginning on November 1, 2018. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). ASU 2016-02 requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. We are currently evaluating the impact of ASU 2016-02, which is effective for the Company in our fiscal year and interim periods beginning on November 1, 2019. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 requires revenue recognition to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 sets forth a new revenue recognition model that requires identifying the contract, identifying the performance obligations, determining the transaction price, allocating the transaction price to performance obligations and recognizing the revenue upon satisfaction of performance obligations. The amendments in the ASU can be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the update recognized at the date of the initial application along with additional disclosures. We have been monitoring the activity of the FASB and the Transition Resource Group as it relates to specific industry interpretive guidance and further overall interpretations and clarifications. In fiscal year 2017, we began our plan on adoption of ASU 2014-09. Our plan entails activities such as reviewing significant revenue streams (and related costs) and representative contracts to determine the potential changes to existing accounting policies, completion of an accounting guidance gap analysis, and identifying and addressing the impact that ASU 2014-09 will have on business processes, systems and internal controls to support the recognition and disclosure requirements. We are currently in the process of completing our accounting gap analysis. We are currently evaluating the full impact of ASU 2014-09 and related amendments on our consolidated financial statements and related disclosures. Currently, we have not identified any material expected changes due to the adoption of ASU 2014-09 on the Company’s consolidated financial statements, and are in the process of quantifying the impact. We plan to adopt ASU 2014-09, in our fiscal year and interim periods beginning on November 1, 2018 and we currently expect to apply the modified retrospective transition method. This would result in an adjustment to retained earnings for the cumulative effect, if any, of applying the ASU 2014-09 to contracts in process as of the adoption date. Under this method, the Company would not restate the prior consolidated financial statements presented. However, the Company would include additional disclosures of the amount by which each financial statement line item is affected in the current reporting period during our fiscal year 2019, as compared to the guidance that was in effect before the change, and an explanation of the reasons for significant changes, if any. Accounting Pronouncements Recently Adopted In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. Under current guidance, an entity subsequently measures inventory at the lower of cost or market, with market defined as replacement cost, net realizable value (NRV), or NRV less a normal profit margin. An entity uses current replacement cost provided that it is not above NRV (i.e., the ceiling) or below NRV less an approximately normal profit margin (i.e., the floor). ASU 2015-11 eliminates this analysis and requires entities to measure inventory “at the lower of cost and NRV.” ASU 2015-11 is effective prospectively for annual periods beginning after December 15, 2016, and interim periods therein. The Company adopted this guidance on November 1, 2017, and it did not have a material impact on the Company's reported financial results.
