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.

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 three months ended March 31, 2018 and April 1, 2017, the change in the U.S. dollar value of the Company's euro denominated debt was an increase of $16,047 ($13,043 net of taxes) and $6,781 ($4,238 net of taxes), respectively, 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 - Recently Adopted On January 1, 2018, the Company adopted the new accounting standard, ASC 606, Revenue from Contracts with Customers and all the related amendments (“ASC 606”) and applied the provisions of the standard to all contracts using the modified retrospective method. The cumulative effect of adopting the new revenue standard was immaterial and no adjustment has been recorded to the opening balance of retained earnings. Prior year information has not been restated and continues to be reported under the accounting standards in effect for those periods. Substantially all of the Company’s revenue continues to be recognized at a point in time when the product is either shipped or received from the Company's facilities and control of the product is transferred to the customer. The Company reviewed all of its revenue product categories under ASC 606 and the only changes identified were that an immaterial amount of revenue from intellectual property ("IP") contracts result in earlier recognition of revenue, new controls and processes designed to meet the requirements of the standard were implemented, and the required new disclosures are presented in Note 3, Revenue from Contracts with Customers. The adoption of ASC 606 did not have a material impact on the amounts reported in the Company's consolidated financial position, results of operations or cash flows. On January 1, 2018, the Company adopted the new accounting standard, ASU 2016-15, Statement of Cash Flows (Topic 230). The effect of adopting the new standard was not material. On January 1, 2018, the Company adopted the new accounting standard, ASU 2017-01, Business Combinations (Topic 805): Clarifying the definition of a business. The effect of adopting the new standard was not material. Recent Accounting Pronouncements - Effective in Future Years 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, including identification of new controls and processes designed to meet the requirements of the topic and required new disclosures upon adoption, and may identify additional impacts this guidance will have on its consolidated financial statements and disclosures. In January 2017, the FASB 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.
