Accounting Policies [Abstract] |
Significant Accounting Policies [Text Block] | Summary of Significant Accounting Policies The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. The Company’s significant accounting policies have not materially changed during the nine months ended October 1, 2017. Recent accounting pronouncements Accounting Pronouncement Recently Adopted In March 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting" (Topic 718), which simplifies the accounting for share-based payment transactions. The new guidance requires excess tax benefits and tax deficiencies to be recorded in the income statement when stock awards vest or are settled. In addition, cash flows related to excess tax benefits will no longer be separately classified as an inflow from financing activities with a corresponding outflow from operating activities but will be classified along with other income tax cash flows as an operating activity. The standard also allows the entity to repurchase more of an employee’s vesting shares for tax withholding purposes without triggering liability accounting, clarifies that all cash payments made to tax authorities on an employee’s behalf for withheld shares should be presented as a financing activity on the cash flows statement, and provides an accounting policy election to account for forfeitures as they occur. The new guidance became effective for the Company in the first quarter of fiscal 2017. Upon adoption on January 1, 2017, the Company prospectively recorded all excess tax benefits and tax deficiencies arising from stock awards vesting or settlement as income tax expense or benefit rather than in equity. For the three and nine months ended October 1, 2017, the impact of the adoption was the recognition of $0.3 million and $2.1 million, respectively, excess tax benefits as a component of the provision for income taxes. The Company elected to account for forfeitures as they occur, rather than estimating expected forfeitures, which resulted in net cumulative-effect adjustment of $0.2 million decrease to retained earnings as of January 1, 2017. The Company elected to apply the presentation requirements for cash flows related to excess tax benefits retrospectively to all periods presented, which resulted in an increase to both net cash provided by operating activities and net cash used in financing activities of $2.3 million for the nine months ended October 2, 2016, respectively, on the unaudited condensed consolidated statements of cash flows. The presentation requirement for cash flows related to employee taxes paid for withheld shares had no impact to any of the periods presented on the consolidated statements of cash flows since the Company has historically been presented such cash flows as a financing activity. Accounting Pronouncements Not Yet Effective In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers" (Topic 606), which was further updated in March, April, May and December 2016. The guidance in this update supersedes the revenue recognition requirements in Topic 605, "Revenue Recognition". Under the new guidance, an entity should recognize revenue to depict the transfer of promised 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. The guidance also specifies the accounting for some costs to obtain or fulfill a contract with a customer. An entity should apply the amendments in the update either retrospectively to each prior reporting period presented (full retrospective method) or retrospectively with the cumulative effect of initially applying this update recognized at the date of initial application (modified retrospective method). On July 9, 2015, the FASB concluded to delay the effective date of the new revenue standard by one year. ASU 2014-09 is effective for the Company beginning in the first quarter of fiscal 2018 and early adoption is permitted. The Company anticipates adopting the new standard effective January 1, 2018. The Company has identified major revenue streams, performed an analysis of a sample of contracts to evaluate the impact of the standard, and begun the drafting of its accounting policies and evaluating the new disclosure requirements. To date, the Company believes the new standard could impact the amount or the timing of its revenue on a go forward basis and could impact the timing, but not the amount, of past recognition. The new standard requires entities to determine the separate units of account or ‘‘performance obligations’’ in their customer contracts. The Company is still in the process of evaluating the impact of this guidance with respect to its multiple performance obligations and the resulting accounting treatment. Furthermore, the Company believes it will be impacted by the requirement of the new standard to estimate for yet to be committed sales incentives at the time revenue is recognized. Under Topic 605, these incentives are recognized as a reduction of revenue at the later of when the related revenue is recognized or when the program is offered to the channel partner. Applying Topic 606, where customary business practice of providing such incentives is determined, there is a timing difference and will require the Company upon adoption to record an estimate of yet to be committed future sales incentives with respect to revenue already recognized. The actual impact upon adoption will be based on open contracts existing at the earlier of the period presented under either full retrospective method or modified retrospective method, whichever the Company choses to adopt. In addition, the Company has determined that the presentation of certain reserve balances currently shown net within accounts receivable will be presented as refund liabilities within current liabilities upon adoption. The Company expects to complete the assessment process, including selecting a transition method for adoption, and to complete the implementation process, including adding procedures and evaluating necessary disclosures, prior to the first quarter of fiscal 2018. In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities" (Subtopic 825-10), which addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. This guidance requires equity investments to be measured at fair value with changes in fair value recognized in net income. This guidance simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. This guidance also clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The Company expects to adopt the new guidance in the first quarter of fiscal 2018, when it is effective for the Company. The Company is currently evaluating the impact the guidance will have on its financial statements and related disclosures, including accounting policies and processes. To date, the Company believes the most significant impact will be that the adoption of the new guidance could increase the volatility of its other income (expense), net, as a result of the re-measurement of its equity securities that are classified as cost method investments under the current guidance upon the occurrence of observable price changes and impairments. In February 2016, FASB issued ASU 2016-02, "Leases" (Topic 842), which requires lessees to recognize on the balance sheets a right-of-use asset, representing its right to use the underlying asset for the lease term, and a corresponding lease liability for all leases with terms greater than twelve months. The liability will be equal to the present value of lease payments while the right-of-use asset will be based on the liability, subject to adjustment, such as for initial direct costs. In addition, ASU 2016-02 expands the disclosure requirements for lessees. Upon adoption, the Company will be required to record a lease asset and lease liability related to its operating leases. ASU 2016-02 will be applied using a modified retrospective transition method and is effective for the Company in the first quarter fiscal 2019, with early adoption permitted. The Company does not plan to early adopt the guidance and is currently evaluating the impact the update will have on its financial position, results of operations and cash flows and related disclosures. In June 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments" (Topic 326), which replaces the incurred-loss impairment methodology and requires immediate recognition of estimated credit losses expected to occur for most financial assets, including trade receivables. Credit losses on available-for-sale debt securities with unrealized losses will be recognized as allowances for credit losses limited to the amount by which fair value is below amortized cost. ASU 2016-13 is effective for the Company beginning in the first quarter of 2020 and early adoption is permitted. The Company continues to assess the potential impact of the new guidance, but does not expect it to have material impacts on its financial position, results of operations or cash flows. In October 2016, the FASB issued ASU 2016-16, "Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory" (Topic 740), which requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. This removes the exception to postpone recognition until the asset has been sold to an outside party. ASU 2016-16 is effective for the Company in the first quarter of fiscal 2018 and early adoption is permitted. The Company does not plan to early adopt the guidance. Upon adoption, the Company anticipates the recognition of a deferred tax asset estimated at $30 million resulting from differences in the tax basis of assets and the consolidated book basis of assets resulting from intra-entity transfers of intangible assets. Other than the recognition of the deferred tax asset that will be established in retained earnings upon adoption, the Company estimates that adoption of the standard will increase tax expense by an approximate $1.5 million annually. The Company does not anticipate it to have a material impact on its cash flows. In January 2017, the FASB issued ASU 2017-01, "Business Combinations: Clarifying the Definition of a Business" (Topic 805), which changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. ASU 2017-01 is effective for the Company in the first quarter of fiscal 2018 and early adoption is permitted. The guidance should be applied prospectively to any transactions occurring on or after the adoption date. The Company does not expect it to have material impacts on its financial position, results of operations or cash flows. In January 2017, the FASB issued ASU 2017-04, "Intangibles-Goodwill and Other: Simplifying the Test for Goodwill Impairment" (Topic 350), which simplifies the subsequent measurement of goodwill by removing Step 2 of goodwill impairment test that requires the determination of the fair value of individual assets and liabilities of a reporting unit. The new guidance requires goodwill impairment to be measured as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 will be applied prospectively and is effective for the Company in the first quarter of fiscal 2020, with early adoption permitted. The Company does not expect it to have material impacts on its financial position, results of operations or cash flows. In May 2017, the FASB issued ASU 2017-09, "Compensation—Stock Compensation: Scope of Modification Accounting" (Topic 718), which clarifies when changes to the terms or conditions of a share-based payment award must by accounted for as modifications. Under the new guidance, an entity will not apply modification accounting if the award's fair value, vesting conditions and classification are the same immediately before and after the change. ASU 2017-09 is effective for the Company in the first quarter of fiscal 2018 and early adoption is permitted. The guidance should be applied prospectively to award modified on or after the adoption date. The Company does not expect it to have material impacts on its financial position, results of operations or cash flows. In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities" (Topic 815), which expands and refines hedge accounting for both non-financial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The guidance also makes certain targeted improvements to simplify the application of hedge accounting guidance and ease the administrative burden of hedge documentation requirements and assessing hedge effectiveness. ASU 2017-12 is effective for the Company in the first quarter of fiscal 2019 and early adoption is permitted. Entities should apply the guidance to existing cash flow and net investment hedge relationships using a modified retrospective approach with a cumulative effect adjustment recorded to opening retained earnings on the date of adoption. The guidance also provides transition relief to make it easier for entities to apply certain amendments to existing hedges where the hedge documentation needs to be modified. The Company is currently evaluating what impact, if any, the adoption of this guidance will have on its financial position, results of operations and cash flows.
