3 Months Ended

Mar. 30, 2019

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and footnotes included in our Annual Report on Form 10-K for the year ended December 31, 2018.

Principles of consolidation

all adjustments (consisting of normal recurring accruals and other adjustments) considered necessary for a fair presentation of the unaudited Condensed Consolidated Financial Statements have been included and include our accounts and the accounts of all majority-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

Recently Issued Accounting Standards

Recent Accounting Standard Pronouncements

Below are recent Accounting Standard Updates ("ASU") that we are still assessing to determine the effect on our Condensed Consolidated Financial Statements. We do not believe that any other recently issued accounting standards could have a material effect on our Condensed Consolidated Financial Statements. As new accounting pronouncements are issued, we will adopt those that are applicable under the circumstances.



Recently Issued Accounting Standards Not Yet Adopted
Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters
ASU 2018-15: Intangibles-Goodwill and Other- Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract	This guidance requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred.	January 1, 2020	We currently plan to adopt the standard prospectively on the effective date. Upon adoption, no impact is currently expected, however, future hosting arrangements treated as service contracts will need to be evaluated for capitalizable costs during implementation. The Consolidated Financial Statement impact will align with the presentation of the underlying hosting contracts, which will be included within Operating expenses.
ASU 2018-13: Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement	This guidance amends ASC 820 to add, remove, and modify certain disclosure requirements for fair value measurements.	January 1, 2020	We currently plan to adopt the standard on the effective date. Upon adoption, we will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurement. We will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy.
ASU 2017-04 Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill	The objective of this update is to reduce the cost and complexity of subsequent goodwill accounting and simplify the impairment test by removing the Step 2 requirement to perform a hypothetical purchase price allocation when the carrying value of a reporting unit exceeds its fair value. If a reporting unit’s carrying value exceeds its fair value, an entity would record an impairment charge based on that difference, limited to the amount of goodwill attributed to that reporting unit. This will not change the guidance on completing Step 1 of the goodwill impairment test and would be applied prospectively. Early adoption is permitted.	January 1, 2020	We currently plan to adopt the standard prospectively on the effective date. Upon adoption, we will no longer be required to calculate the implied fair value of goodwill to measure a goodwill impairment. Rather, a Step 1 failure will result in an immediate impairment charge based on the carrying value of the reporting unit.
ASU 2016-13: Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ASU 2018-19 Codification Improvements for Topic 326: Measurement of Credit Losses on Financial Instruments	This guidance changes the impairment model for most financial assets and certain other instruments, replacing the current "incurred loss" approach with an "expected loss" credit impairment model, which will apply to most financial assets measured at amortized cost, and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities and off-balance sheet credit exposures such as letters of credit.	January 1, 2020	We are currently evaluating the implications of adoption on our Consolidated Financial Statements.
ASU 2018-18 Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606	This guidance amends ASC 808 to clarify that certain transactions between participants in a collaborative arrangement should be accounted for under ASC 606 when the counterparty is a customer. The proposed guidance would be applied retrospectively to the date of initial adoption of Topic 606.	January 1, 2020	We are currently evaluating the implications of adoption on our Consolidated Financial Statements.
ASU 2018-14: Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans	This guidance amends ASC 715 to add, remove, and clarify disclosure requirements related to defined benefit pension and other post-retirement plans.	December 31, 2020	We are currently evaluating the implications of adoption on our Consolidated Financial Statements.

Derivatives instruments and hedging

On January 1, 2019, we adopted Accounting Standards Update No. 2017-12 Targeted Improvements to Accounting for Hedge Activities ("ASU 2017-12") using a modified retrospective approach. Among other provisions, the new standard required modifications to existing presentation and disclosure requirements on a prospective basis. As such, certain disclosures for the three months ended March 31, 2018 and the year ended December 31, 2018 below conform to the disclosure requirements prior to the adoption of ASU 2017-12.

Prior to the adoption of ASU 2017-12, we were required to separately measure and reflect the amount by which the hedging instrument did not offset the changes in the fair value or cash flows of hedged items, which was referred to as the ineffective amount. We assessed hedge effectiveness on a quarterly basis and recorded the gain or loss related to the ineffective portion of derivative instruments, if any, in Other (income) expense, net on the Condensed Consolidated Statements of Operations. Pursuant to the provisions of ASU 2017-12, we are no longer required to separately measure and recognize hedge ineffectiveness. Therefore, we no longer recognize hedge ineffectiveness separately on our Condensed Consolidated Statements of Income, but instead recognize the entire change in the fair value of:


•	Cash flow hedges included in the assessment of hedge effectiveness in OCI. The amounts recorded in OCI will subsequently be reclassified to earnings in the same line item on the Condensed Consolidated Statements of Operations as impacted by the hedged item when the hedged item affects earnings; and


•	Fair value hedges included in the assessment of hedge effectiveness in the same line item on the Condensed Consolidated Statements of Operations that is used to present the earnings effect of the hedged item.

Prior to the adoption of ASU 2017-12, we excluded option premiums and forward points (excluded components) from our assessment of hedge effectiveness for our foreign exchange cash flow hedges. We recognized all changes in fair value of the excluded components in Other (income) expense, net, on the Condensed Consolidated Statements of Operations. The amendments in ASU 2017-12 continue to allow those components to be excluded from the assessment of hedge effectiveness and add cross-currency basis spread as an allowable excluded component. The provisions of ASU 2017-12 allow a policy election to either continue to recognize changes in the fair value of the excluded components currently in earnings or to recognize the initial value of the excluded component using an amortization approach. We have elected to recognize the initial value of the excluded component on a straight-line basis over the life of the derivative instrument, within the same line item on the Condensed Consolidated Statements of Operations that is used to present the earnings effect of the hedged item. The cumulative effect adjustment between Accumulated Other Comprehensive Income ("AOCI") and Retained earnings (accumulated deficit) from applying this policy on existing hedges at the date of adoption was immaterial.

We record derivative instruments on the balance sheet on a gross basis as either an asset or liability measured at fair value (refer to Note 5). Additionally, changes in a derivative's fair value, which are measured at the end of each period, are recognized in earnings unless a derivative can be designated in a qualifying hedging relationship.

Designated derivatives meet hedge accounting criteria, which means the fair value of the hedge is recorded in shareholders’ equity as a component of OCI, net of tax. The deferred gains and losses are recognized in income in the period in which the hedged item affects earnings. We have elected to recognize the fair value of the excluded component in OCI and amortize on a straight-line basis over the life of the derivative instrument, within the same line item on the Condensed Consolidated Statements of Operations that is used to present the earnings effect of the hedged item. All of our designated derivatives are assessed for hedge effectiveness quarterly. All of our designated derivatives were classified as cash flow hedges as of March 30, 2019 and December 31, 2018.

We also have economic non-designated derivatives that do not meet hedge accounting criteria. These derivative instruments are adjusted to current market value at the end of each period through earnings. Gains or losses on these instruments are offset substantially by the remeasurement adjustment on the hedged item.

We are exposed to credit loss in the event of nonperformance by the counterparties on derivative contracts. It is our policy to manage our credit risk on these transactions by dealing only with financial institutions having a long-term credit rating of "Aa3" or better and by distributing the contracts among several financial institutions to diversify credit concentration risk. Should a counterparty default, our maximum exposure to loss is the asset balance of the instrument. The maximum term of our forward currency exchange contracts is 18 months.

We enter into certain derivative financial instruments, when available on a cost-effective basis, to mitigate our risk associated with changes in interest rates and foreign currency exchange rates as follows:

Interest rate risk management - We are exposed to the impact of interest rate changes through our cash investments and borrowings. We utilize a variety of strategies to manage the impact of changes in interest rates including using a mix of debt maturities along with both fixed-rate and variable-rate debt. In addition, we may enter into treasury-lock agreements and interest rate swap agreements on certain investing and borrowing transactions to manage our exposure to interest rate changes and our overall cost of borrowing.

Foreign currency exchange risk management - We conduct business in several major currencies other than the U.S. dollar and are subject to risks associated with changing foreign exchange rates. Our objective is to reduce cash flow volatility associated with foreign exchange rate changes on a consolidated basis to allow management to focus its attention on business operations. Accordingly, we enter into various contracts that change in value as foreign exchange rates change to protect the value of existing foreign currency assets and liabilities, commitments, and anticipated foreign currency sales and expenses.

All derivative instruments are managed on a consolidated basis to efficiently net exposures and thus take advantage of any natural offsets. Gains and losses related to the derivative instruments are expected to be offset largely by gains and losses on the original underlying asset or liability. We do not use derivative financial instruments for speculative purposes.

Leases

We adopted ASU 2016-02, Leases ("Topic 842"), as of January 1, 2019, using the modified retrospective transition approach, with a cumulative-effect adjustment to the opening balance of retained earnings as of the effective date. The financial results reported in periods prior to 2019 are unchanged. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classification.

Adoption of the new standard resulted in additional operating lease liabilities and lease assets, including the transition of existing capital lease liabilities and lease assets to finance classification, of approximately $166.5 million and $164.0 million, respectively, as of January 1, 2019. Upon adoption, the difference between the lease assets and lease liabilities partially related to existing deferred lease liabilities reclassified to lease assets and the transition of capital lease assets and liabilities at their carrying values. In addition, historical build-to-suit assets and liabilities were removed on transition and recorded as an adjustment to retained earnings, net of deferred tax impact. The standard did not materially impact our consolidated net income or cash flow classification.

We lease certain office buildings, warehouse facilities, vehicles, and plant, office, and computer equipment. Lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease.

We evaluate arrangements at inception to determine if lease components are included. An arrangement includes a lease component if it identifies an asset and we have control over the asset. For new leases beginning January 1, 2019 or later, we have elected for all asset classes not to separate lease components from the non-lease components included in an arrangement when measuring the leased asset and leased liability.

Lease assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet. We recognize lease expense for leases on a straight-line basis over the lease term. We apply the portfolio approach to certain groups of computer equipment and vehicle leases when the term, classification, and asset type are identical. The discount rate selected is the incremental borrowing rate we would obtain for a secured financing of the lease asset over a similar term.

Many of our leases include one or more options to extend the lease term. Certain leases also include options to terminate early or purchase the leased property, all of which are executed at our sole discretion. Optional periods may be included in the lease term and measured as part of the lease asset and lease liability if we are reasonably certain to exercise our right to use the leased asset during the optional periods. We generally consider

renewal options to be reasonably certain of execution and included in the lease term when significant leasehold improvements have been made by us to the leased assets. The depreciable lives of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.

Certain of our lease agreements include contingent rental payments based on per unit usage over contractual levels (e.g., miles driven, or machine hours used) and others include rental payments adjusted periodically for market reviews or inflationary indexes. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.
