Accounting Policies [Abstract]
General	General Interim Reporting The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with instructions to Form 10-Q and do not include all of the information and footnotes required by U.S. generally accepted accounting principles ("U.S. GAAP") for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. These statements should be read in conjunction with the consolidated financial statements and notes thereto, and the Company’s description of critical accounting policies, included in the Company’s 2016 Annual Report on Form 10-K, as filed with the Securities and Exchange Commission. Results for interim periods are not necessarily indicative of the results for the year. Hedges of Net Investments in Non-U.S. Operations The Company has numerous investments outside the United States. The net assets of these subsidiaries are exposed to changes and volatility in currency exchange rates. The Company uses foreign currency denominated debt to hedge some of its non-U.S. net investments against adverse movements in exchange rates. The gains and losses on the Company's net investments in its non-U.S. operations are partially economically offset by gains and losses on its foreign currency borrowings. The Company designated its €500,000 2.00% Senior Notes borrowing as a net investment hedge against a portion of its European operations. For the nine months ended September 30, 2017, the change in the U.S. dollar value of the Company's euro denominated debt was an increase of $64,684 ($40,427 net of taxes), which is recorded in the foreign currency translation adjustment component of other comprehensive income (loss). The increase in the U.S. dollar value of the Company's debt partially offsets the euro-to-dollar translation of the Company's net investment in its European operations. Recent Accounting Pronouncements - Effective in Future Years In May 2014, the FASB issued Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers. This topic converges the guidance within U.S. GAAP and International Financial Reporting Standards ("IFRS") and supersedes ASC 605, Revenue Recognition. The new standard requires companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. The new standard will also result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively, and improve guidance for multiple-element arrangements. The new guidance is effective for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period and early application is not permitted. On July 9, 2015, the FASB decided to defer the effective date of ASC 606 for one year. The deferral results in the new revenue standard being effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2017. The Company will adopt the provisions of this new accounting standard at the beginning of fiscal year 2018, using the cumulative effect method. The Company continues to analyze the adoption of ASC 606, including certain contracts that could result in a change in the timing of the recognition of revenue, the identification of new controls and processes designed to meet the requirements of the standard, and the required new disclosures upon adoption. At this time ASC 606 is not expected to have a material impact on the amounts reported in the Company's consolidated financial position, results of operations or cash flows. In February 2016, the FASB issued ASU 2016-02, Leases. The amendments in this Update create Topic 842, Leases, and supersede the requirements in Topic 840, Leases. Topic 842 specifies the accounting for leases. The objective of Topic 842 is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. The guidance in this update is effective for annual reporting periods beginning after December 15, 2018 including interim periods within that reporting period and early adoption is permitted. The Company plans to adopt the provisions of this update at the beginning of fiscal year 2019. Based on a preliminary assessment, the Company expects the adoption of this guidance to have a material impact on its assets and liabilities due to the recognition of right-of-use assets and lease liabilities on its consolidated balance sheets at the beginning of the earliest period presented. The Company is continuing its assessment, which may identify additional impacts this guidance will have on its consolidated financial statements and disclosures. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230). This update clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. ASU 2016-15 also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. Additionally, the FASB issued ASU 2016-18 in November 2016 to address the classification and presentation of changes in restricted cash on the statement of cash flows. The guidance in these updates should be applied retrospectively and are effective for fiscal years beginning after December 15, 2017, and interim periods within those years. Early adoption is permitted. The Company plans to adopt the provisions of these updates at the beginning of fiscal year 2018 and is currently assessing the impact on its consolidated statement of cash flows. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the definition of a business. The amendments clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of businesses. The guidance in this update is effective for fiscal years beginning after December 15, 2017, and interim periods within those years. In January 2017, the FASB also issued ASU 2017-04, Intangibles - Goodwill and other (Topic 350): Simplifying the test for goodwill impairment. The amendments remove the second step of the current goodwill impairment test. An entity will apply a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit's carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The new guidance does not amend the optional qualitative assessment of goodwill impairment. This guidance is effective for impairment tests in fiscal years beginning after December 15, 2019. Recent Accounting Pronouncements - Recently Adopted In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. This update changes the measurement principle for inventory for entities using FIFO or average cost from the lower of cost or market to lower of cost and net realizable value. Entities that measure inventory using LIFO or the retail inventory method are not affected. This update will more closely align the accounting for inventory under U.S. GAAP with IFRS. The Company currently accounts for inventory using the FIFO method. The Company adopted the provisions of this update at the beginning of fiscal year 2017. This update did not have a material impact on the Company's consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. This update simplifies several aspects of the accounting for employee share-based payment transactions for both public and nonpublic entities, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Company adopted the provisions of this update at the beginning of fiscal year 2017, with the statement of cash flows classifications applied retrospectively. Accordingly, cash paid for shares redeemed for taxes of $11,879 was reclassed to financing activities from operating activities for the nine months ended October 1, 2016. Additionally, excess tax benefits are now classified with other tax flows as an operating activity with $3,782 reclassified from financing activities for the nine months ended October 1, 2016. The Company has also elected to continue to estimate the number of awards that are expected to vest when accounting for forfeitures.
