Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP), and include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. As further discussed below in this Note 2 to these consolidated financial statements, the Company adopted Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2014-09, Revenue (Topic 606): Revenue from Contracts with Customers (ASU 2014-09) and ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other than Inventory (ASU 2016-16) effective December 31, 2017. All prior period amounts and disclosures set forth in this Annual Report on Form 10-K have been updated to comply with the applicable method of adoption, as indicated by the “as adjusted” notation.
Fiscal Periods | Fiscal Periods The Company follows a conventional 52/53 week fiscal year. Under a conventional 52/53 week fiscal year, a 52 week fiscal year includes four quarters of 13 fiscal weeks while a 53 week fiscal year includes three 13 fiscal week quarters and one 14 fiscal week quarter. The Company’s last 53 week fiscal year was fiscal year 2014. Fiscal year 2018 is a 52 week fiscal year. All references to years in these notes to consolidated financial statements are fiscal years unless otherwise noted.
Use of Estimates | Use of Estimates The Company prepares its financial statements in conformity with GAAP, which requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates include the determination of accounts receivable allowances, inventory reserves, warranty reserves, rebate accruals, valuation of the Company’s equity awards, goodwill valuation, deferred taxes and any associated valuation allowances, royalty revenues, deferred revenue, deferred costs, uncertain income tax positions, and litigation costs and related accruals. In addition, for the year ended December 30, 2017, certain estimates were made in calculating the provision for income taxes related to the impact of the Tax Cuts and Jobs Act of 2017 (2017 Tax Act). Actual results could differ from such estimates.
Reclassifications | Reclassifications Certain amounts in the consolidated financial statements for prior periods have been reclassified to conform to the current period presentation.
Fair Value Measurements | Fair Value Measurements Authoritative guidance describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:
• | Level 1 - Quoted prices in active markets for identical assets or liabilities.
• | Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that can be corroborated by observable market data for substantially the full term of the assets or liabilities.
• | Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Pursuant to current authoritative guidance, entities are allowed an irrevocable option to elect the fair value for the initial and subsequent measurement for specified financial assets and liabilities on a contract-by-contract basis. The Company did not elect to apply the fair value option under this guidance to specific assets or liabilities on a contract-by contract basis. There were no transfers between Level 1, Level 2 and Level 3 inputs during the years ended December 29, 2018 or December 30, 2017. The Company carries cash and cash equivalents at cost which approximates fair value. As of December 29, 2018 and December 30, 2017, the Company had an insignificant amount of other financial assets that were required to be measured under the fair value hierarchy, the measurement of which were based on Level 1 and Level 2 inputs.
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity from date of purchase of three months or less, or highly liquid investments that are readily convertible into known amounts of cash, to be cash equivalents.
Accounts Receivable and Allowance for Doubtful Accounts | Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable consist of trade receivables recorded upon recognition of product revenues, reduced by reserves for estimated bad debts and returns. Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Credit is extended based on an evaluation of the customer’s financial condition. Collateral is generally not required. The allowance for doubtful accounts is determined based on historical write-off experience, current customer information and other relevant factors, including specific identification of past due accounts, based on the age of the receivable in excess of the contemplated or contractual due date. Accounts are charged off against the allowance when the Company believes they are uncollectible.
Inventories | Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined using a standard cost method, which approximates the first in, first out method, and includes material, labor and overhead costs. Inventory reserves are recorded for inventory items that have become excess or obsolete or are no longer used in current production and for inventory items that have a market price less than carrying value in inventory.
Property and Equipment | Property and Equipment Property and equipment are stated at cost. Depreciation is calculated using the straight-line method over estimated useful lives as follows:
| Useful Lives
Aircraft and components | 10 to 20 years
Buildings | 39 years
Building improvements | 7 to 15 years
Computer equipment | 2 to 6 years
Demonstration units | 3 years
Furniture and office equipment | 2 to 6 years
Leasehold improvements | Lesser of useful life or term of lease
Machinery and equipment | 5 to 10 years
Tooling | 3 years
Vehicles | 5 years
Land is not depreciated and construction in progress is not depreciated until placed in service. Normal repair and maintenance costs are expensed as incurred, whereas significant improvements that materially increase values or extend useful lives are capitalized and depreciated over the remaining estimated useful lives of the related assets. Upon sale or retirement of depreciable assets, the related cost and accumulated depreciation or amortization are removed from the accounts and any gain or loss on the sale or retirement is recognized in income. For the years ended December 29, 2018, December 30, 2017 and December 31, 2016, depreciation and amortization expense of property and equipment was $16.3 million, $15.2 million and $13.0 million, respectively.
Intangible Assets | Intangible Assets Intangible assets consist primarily of patents, trademarks, software development costs, customer relationships and acquired technology. Costs related to patents and trademarks, which include legal and application fees, are capitalized and amortized over the estimated useful lives using the straight-line method. Patent and trademark amortization commences once final approval of the patent or trademark has been obtained. Patent costs are amortized over the lesser of 10 years or the patent’s remaining legal life, which assumes renewals, and trademark costs are amortized over 17 years, and their associated amortization cost is included in selling, general and administrative expense in the accompanying consolidated statements of operations. For intangibles purchased in an asset acquisition or business combination, which mainly include patents, trademarks, customer relationships and acquired technology, the useful life is determined in the same manner as noted above. The Company’s policy is to renew its patents and trademarks. Costs to renew intangibles are capitalized and amortized over the remaining useful life of the intangible. The Company continually evaluates the amortization period and carrying basis of patents and trademarks to determine whether any events or circumstances warrant a revised estimated useful life or reduction in value. Capitalized application costs are charged to operations when it is determined that the patent or trademark will not be obtained or is abandoned. For the years ended December 29, 2018, December 30, 2017 and December 31, 2016, amortization of intangible assets was $4.8 million, $4.9 million and $3.8 million, respectively. As of December 29, 2018 and December 30, 2017, the total costs of patents not yet amortizing was $5.3 million and $4.3 million, respectively. As of December 29, 2018 and December 30, 2017, the total costs of trademarks not yet amortizing was $0.5 million and $0.6 million, respectively. For the years ended December 29, 2018 and December 30, 2017, total renewal costs capitalized for patents and trademarks was $0.5 million and $0.6 million, respectively. As of December 29, 2018, the weighted-average number of years until the next renewal was one year for patents and five years for trademarks. Costs related to the research and development of new software products and enhancements to existing software products are expensed as incurred until technological feasibility of the product has been established, at which time such costs are capitalized, subject to expected recoverability. For the years ended December 29, 2018 and December 30, 2017, the Company capitalized $0.7 million and $0.2 million of software development costs, respectively. For the year ended December 31, 2016, the Company did not capitalize any software development costs. The capitalized costs are amortized over the estimated life of the products, which is generally seven years. For the years ended December 29, 2018, December 30, 2017 and December 31, 2016, the Company amortized $2.0 million, $1.9 million and $1.8 million of capitalized costs, respectively. The Company had unamortized software development costs of $1.4 million and $0.8 million at December 29, 2018 and December 30, 2017, respectively, which is included within intangible assets, net, on the consolidated balance sheets.
Impairment of Goodwill, Intangible Assets and Other Long-Lived Assets | Impairment of Goodwill, Intangible Assets and Other Long-Lived Assets Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the acquired net tangible and intangible assets. Goodwill is not amortized, but instead is tested annually for impairment, or more frequently when events or changes in circumstances indicate that goodwill might be impaired. In assessing goodwill impairment for each of its reporting units, the Company has the option to first assess the qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The Company’s qualitative assessment of the recoverability of goodwill considers various macroeconomic, industry-specific and Company-specific factors, including: (i) severe adverse industry or economic trends; (ii) significant Company-specific actions; (iii) current, historical or projected deterioration of the Company’s financial performance; or (iv) a sustained decrease in the Company’s market capitalization below its net book value. If, after assessing the totality of events or circumstances, the Company determines it is unlikely that the fair value of a reporting unit is less than its carrying amount, then a quantitative analysis is unnecessary. However, if the Company concludes otherwise, or if the Company elects to bypass the qualitative analysis, then the Company must perform a quantitative analysis that compares the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not considered impaired; otherwise, a goodwill impairment loss is recognized for the lesser of: (a) the amount that the carrying amount of a reporting unit exceeds its fair value; or (b) the amount of the goodwill allocated to that reporting unit. The annual impairment test is performed during the fourth fiscal quarter. The Company reviews long-lived assets and identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted operating cash flows expected to be generated by the asset. If such asset is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount exceeds the fair value of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.
Income Taxes | Income Taxes The Company accounts for income taxes using the asset and liability method, under which the Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and for net operating loss and tax credit carryforwards. Tax positions that meet a more-likely-than-not recognition threshold are recognized in the first reporting period that it becomes more-likely-than-not such tax position will be sustained upon examination. A tax position that meets this more-likely-than-not recognition threshold is recorded at the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Previously recognized income tax positions that fail to meet the recognition threshold in a subsequent period are derecognized in that period. Differences between actual results and the Company’s assumptions, or changes in the Company’s assumptions in future periods, are recorded in the period they become known. The Company records potential accrued interest and penalties related to unrecognized tax benefits in income tax expense. As a multinational corporation, the Company is subject to complex tax laws and regulations in various jurisdictions. The application of tax laws and regulations is subject to legal and factual interpretation, judgment and uncertainty. Tax laws themselves are subject to change as a result of changes in fiscal policy, changes in legislation, evolution of regulations and court rulings. Therefore, the actual liability for U.S. or foreign taxes may be materially different from the Company’s estimates, which could result in the need to record additional liabilities or potentially to reverse previously recorded tax liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. A valuation allowance is recorded against any deferred tax assets when, in the judgment of management, it is more likely than not that all or part of a deferred tax asset will not be realized. In assessing the need for a valuation allowance, the Company considers all positive and negative evidence, including recent financial performance, scheduled reversals of temporary differences, projected future taxable income, availability of taxable income in carryback periods and tax planning strategies. The 2017 Tax Act introduced certain international provisions effective for the Company beginning in the year ended December 29, 2018. As part of these provisions, an accounting policy election is available to either (1) treat taxes due on certain inclusions in U.S. taxable income as a current-period expense when incurred (“period cost method”) or (2) factor such amounts into the measurement of its deferred taxes (“deferred method”). The Company has elected to use the period cost method. See Note 18 - Income Taxes for additional information related to the impact of the 2017 Tax Act on the Company’s tax provision, taxes payable and deferred taxes for the periods presented in these consolidated financial statements.
Revenue Recognition, Deferred Revenue and Other Contract-Related Liabilities | Revenue Recognition, Deferred Revenue and Other Contract Liabilities Effective December 31, 2017, the Company adopted ASU No. 2014-09, Revenue (Topic 606): Revenue from Contracts with Customers (ASU 2014-09). Accounting Standards Codification (ASC) Topic 606 (ASC 606) provides a single, principles-based five-step model to be applied to all contracts with customers and generally provides for the recognition of revenue in an amount that reflects the consideration to which the Company expects to be entitled, net of allowances for estimated returns, discounts or sales incentives, as well as taxes collected from customers that are remitted to government authorities, when control over the promised goods or services are transferred to the customer. The Company derives the majority of its product revenue from four primary sources: (i) direct sales under deferred equipment agreements with end-user hospitals where the Company provides up-front monitoring equipment at no up-front charge in exchange for a multi-year sensor purchase commitment, (ii) other direct sales of noninvasive monitoring solutions to end-user hospitals, emergency medical response organizations and other direct customers; (iii) sales of noninvasive monitoring solutions to distributors who then typically resell to end-user hospitals, emergency medical response organizations and other customers; and (iv) sales of integrated circuit boards to OEM customers who incorporate the Company’s embedded software technology into their multiparameter monitoring devices. Subject to customer credit considerations, the majority of such sales are made on open account using industry standard payment terms based on the geography within which the specific customer is located. The Company enters into agreements to sell its monitoring solutions and services, sometimes as a part of arrangements with multiple performance obligations that include various combinations of product sales, equipment leases and services. In the case of contracts with multiple performance obligations, the authoritative guidance provides that the total consideration be allocated to each performance obligation on the basis of relative standalone selling prices. When a standalone selling price is not readily observable, the Company estimates the standalone selling price by considering multiple factors including, but not limited to, features and functionality of the product, geographies, type of customer, contractual prices pursuant to Group Purchasing Organization (GPO) contracts, the Company’s pricing and discount practices, and other market conditions. While the majority of the Company’s revenue contracts and transactions contain standard business terms and conditions, there are some transactions that contain non-standard business terms and conditions. As a result, contract interpretation, judgment and analysis is required to determine the appropriate accounting, including: (i) the amount of the total consideration, including variable consideration, (ii) how the arrangement consideration should be allocated to each performance obligation when multiple performance obligations exist, including the determination of standalone selling price, (iii) when to recognize revenue on the performance obligations, and (iv) whether uncompleted performance obligations are essential to the functionality of the completed performance obligations. Changes in judgments on these assumptions and estimates could materially impact the timing of revenue recognition. Sales under deferred equipment agreements are generally structured such that the Company agrees to provide at no up-front charge certain monitoring-related equipment, software, installation, training and/or warranty support in exchange for the hospital’s agreement to purchase sensors over the term of the agreement, which generally ranges from three to six years. The Company generally recognizes revenue for performance obligations related to licensed software parameters and monitoring equipment that are sold under deferred equipment agreements with fixed annual commitments at the time such software or monitoring equipment is provided to the customer. Revenue allocable to performance obligations related to sensor sales and monitoring-related equipment leased under deferred equipment agreements is generally recognized as the sensors are provided to the customer over the life of the contract. Revenue from direct sales of products to the Company’s end-user hospitals, emergency medical response organizations and other direct customers, as well as to its distributors, is generally recognized upon shipment or delivery to the customer based on the terms of the contract or underlying purchase order. The Company also earns revenue from the sale of integrated circuit boards and other products, as well as from software parameter licenses, to OEMs under various agreements. Revenue from the sale of products to the OEMs is generally recognized at the time of shipment. Revenue related to software licenses to OEMs is generally recognized upon shipment of the OEM’s product to its customers, as represented to the Company by the OEM. The Company provides certain customers with various sales incentives that may take the form of discounts or rebates. The Company estimates and provides allowances for these programs as a reduction to revenue at the time of sale. In general, customers do not have a right of return for credit or refund. However, the Company allows returns under certain circumstances. At the end of each period, the Company estimates and accrues for these returns as a reduction to revenue. The Company estimates the revenue constraints related to these forms of variable consideration based on various factors, including expected purchasing volumes, prior sales and returns history, and specific contractual terms and limitations. The majority of the Company’s royalty revenue arises from one agreement and is due and payable quarterly in arrears. An estimate of these royalty revenues is recorded quarterly in the period earned based on historical results, adjusted for any new information or trends known to management at the time of estimation. This estimated revenue is adjusted prospectively when the Company receives the royalty report, approximately sixty days after the end of the previous quarter. The Company also recognizes revenue from time-to-time related to NRE services provided to a certain OEM customer. NRE service revenue is generally recognized on a proportionate basis as the costs of performing such services are incurred by the Company. See “Concentrations of Risk” under Note 19 - Commitments and Contingencies for additional information related to these agreements.
Taxes Collected From Customers and Remitted to Governmental Authorities | Taxes Collected From Customers and Remitted to Governmental Authorities The Company’s policy is to present revenue net of taxes collected from customers and remitted to governmental authorities.
Shipping and Handling Costs and Fees | Shipping and Handling Costs and Fees All shipping and handling costs are expensed as incurred and are recorded as a component of cost of goods sold in the accompanying consolidated statements of operations. Charges for shipping and handling billed to customers are included as a component of product revenue.
Deferred Costs and Other Contract Assets | Deferred Costs and Other Contract Assets The costs of monitoring-related equipment leased to hospitals under deferred equipment agreements are generally deferred and amortized to cost of goods sold over the life of the underlying contracts. Some of the Company’s deferred equipment agreements also contain provisions for certain payments to be made directly to the end-user hospital customer at the inception of the arrangement. These contractual incentive payments are generally deferred and amortized on a straight-line basis as contra-revenue over the life of the underlying agreement. The Company records an unbilled contract receivable related to software licenses and monitoring equipment sold under deferred equipment agreements with fixed annual commitments until such amounts are billed to the customer, which generally occurs at the time the sensors are provided over the term of the agreement. The incremental costs of obtaining a contract with a customer are capitalized and deferred if the Company expects such costs to be recoverable over the life of the contract and the contract term is greater than one year. Such deferred costs generally relate to certain incentive sales commissions earned by the Company’s internal sales team in connection with the execution of deferred equipment agreements and are amortized to expense over the expected term of the underlying contract.
Product Warranty | Product Warranty The Company generally provides a warranty against defects in material and workmanship for a period that generally ranges from six to forty-eight months, depending on the product type. In traditional sales activities, including direct and OEM sales, the Company establishes an accrued liability for the estimated warranty costs at the time of revenue recognition, with a corresponding provision to cost of sales. Customers may also purchase extended warranty coverage separately or as part of a deferred equipment agreement. Revenue related to extended warranty coverage is recognized over the extended life of the contract, which is reasonably expected to be the period over which such services will be provided. The related extended warranty costs are expensed as incurred. Changes in the product warranty accrual were as follows (in thousands):
| Year Ended
| December 29, 2018 |  | December 30, 2017 |  | December 31, 2016
Warranty accrual, beginning of period | $ | 1,149 |  |  | $ | 910 |  |  | $ | 1,222 |
Accrual for warranties issued (including specific accrual) | 1,549 |  |  | 1,061 |  |  | 871 |
Changes in pre-existing warranties (including changes in estimates) | 551 |  |  | 332 |  |  | 110 |
Settlements made | (1,339 | ) |  | (1,154 | ) |  | (1,293 | )
Warranty accrual, end of period | $ | 1,910 |  |  | $ | 1,149 |  |  | $ | 910 |
Advertising Costs | Advertising Costs Advertising costs are expensed as incurred. These costs are included in selling, general and administrative expense in the accompanying consolidated statements of operations. Advertising costs for the years ended December 29, 2018, December 30, 2017 and December 31, 2016 were $17.9 million, $17.8 million and $14.3 million, respectively.
Research and Development | Research and Development Costs related to research and development activities are expensed as incurred. These costs include personnel costs, materials, depreciation and amortization on associated tangible and intangible assets and an allocation of facility costs, all of which are directly related to research and development activities.
Litigation Costs and Contingencies | Litigation Costs and Contingencies The Company records a charge equal to at least the minimum estimated liability for a loss contingency or litigation settlement when both of the following conditions are met: (i) information available prior to issuance of the financial statements indicates that it is probable that a liability had been incurred at the date of the financial statements, and (ii) the range of loss can be reasonably estimated. The determination of whether a loss contingency or litigation settlement is probable or reasonably possible involves a significant amount of management judgment, as does the estimation of the range of loss given the nature of contingencies. Liabilities related to litigation settlements with multiple elements are recorded based on the fair value of each element. Legal and other litigation related expenses are recognized as the services are provided. The Company records insurance and other indemnity recoveries for litigation expenses when both of the following conditions are met: (a) the recovery is probable, and (b) collectability is reasonably assured. Insurance recoveries are only recorded to the extent the litigation costs to which they relate have been incurred and recognized in the financial statements. On November 5, 2016, the Company entered into a settlement agreement (Philips Settlement Agreement) with Koninklijke Philips N.V. (Philips N.V.), which, among other things, settled all of the claims, legal proceedings and contractual disputes between the Company, Philips N.V. and its affiliates. Pursuant to the Philips Settlement Agreement, Philips N.V. paid us $300 million, $30 million of which related to certain future performance obligations by the Company and, therefore, was deferred to future periods.
Foreign Currency Translation | Foreign Currency Translation The Company’s international headquarters is in Switzerland, and its functional currency is the U.S. Dollar. The Company has many other foreign subsidiaries, the largest of which are located in Japan and Europe. The functional currencies of these subsidiaries are the Japanese Yen and Euro, respectively. The Company records certain revenues and expenses in foreign currencies. These revenues and expenses are translated into U.S. Dollars based on the average exchange rate for the reporting period. Assets and liabilities denominated in foreign currencies are translated into U.S. Dollars at the exchange rate in effect as of the balance sheet date. Translation gains and losses related to foreign currency assets and liabilities of a subsidiary that are denominated in the functional currency of such subsidiary are included as a component of accumulated other comprehensive income (loss) within the accompanying consolidated balance sheets. Realized and unrealized foreign currency gains and losses related to foreign currency assets and liabilities of the Company or a subsidiary that are not denominated in the underlying functional currency are included as a component of non-operating (income) expense within the accompanying consolidated statements of operations.
Comprehensive Income | Comprehensive Income Comprehensive income includes foreign currency translation adjustments and any related tax benefits that have been excluded from net income and reflected in stockholders’ equity.
Net Income Per Share | Net Income Per Share Basic net income per share is computed by dividing net income by the weighted-average number of shares outstanding during the period. Net income per diluted share is computed by dividing the net income by the weighted-average number of shares and potential shares outstanding during the period, if the effect of potential shares is dilutive. Potential shares include incremental shares of stock issuable upon the exercise of stock options and the vesting of both Restricted Stock Units (RSUs) and Performance Stock Units (PSUs). For the years ended December 29, 2018, December 30, 2017 and December 31, 2016, weighted options to purchase 1.1 million, 0.4 million and 0.2 million shares of common stock, respectively, were outstanding, but were not included in the computation of diluted net income per share because the effect of including such shares would have been antidilutive in the applicable period. For the year ended December 29, 2018, certain RSUs are considered contingently issuable shares as their vesting is contingent upon the occurrence of certain future events. Since such events had not occurred and were not considered probable of occurring as of December 29, 2018, 2.7 million of weighted average shares related to such RSUs have been excluded from the calculation of potential shares. For additional information with respect to these RSUs, please see “Employment and Severance Agreements” in Note 19 to these consolidated financial statements. The computation of basic and diluted net income per share is as follows (in thousands, except per share data):

Segment Information | Segment Information The Company uses the “management approach” in determining reportable business segments. The management approach designates the internal organization used by management for making operating decisions and assessing performance as the source for determining the Company’s reportable segments. Based on this assessment, management has determined it operates in one reportable business segment, which is comprised of patient monitoring and related products
Recently Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Shares-Based Payment Accounting (ASU 2018-07). The new standard aligns the measurement and classification guidance for share-based payments to nonemployees with the guidance for share-based payments to employees. Under this guidance, the measurement of the equity-classified nonemployee awards will be fixed at the grant date and the term used for measurement can be the expected term or the contractual term. ASU 2018-07 is effective for annual and interim fiscal reporting periods beginning after December 15, 2018. The Company early adopted this standard during the year ended December 29, 2018 and such adoption did not have a material impact on its consolidated financial statements. In March 2018, the FASB issued ASU No. 2018-05, Income Taxes (Topic 740) Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (ASU 2018-05). ASU 2018-05 amends certain material in ASC Topic 740 for the income tax accounting implications of the recently issued Tax Cuts and Jobs Act of 2017. The Company early adopted this standard when it was issued. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other than Inventory (ASU 2016-16). The new standard eliminates the exception that allowed the income tax consequences of an intra-entity transfer of assets other than inventory to be deferred until the transferred asset was sold to a third party or otherwise recovered through use, and now requires recognition of such income tax consequences at the time the non-inventory asset is transferred. ASU 2016-16 is effective for annual and interim fiscal reporting periods beginning after December 15, 2017. The standard required companies to apply a modified retrospective approach with a cumulative catch-up adjustment to opening retained earnings in the period of adoption. Accordingly, the Company recorded a $0.4 million decrease to retained earnings and a corresponding increase to deferred tax assets of $0.1 million, and a decrease to prepaid taxes of $0.5 million as of December 31, 2017. Effective December 31, 2017, the Company adopted ASU 2014-09, which introduced ASC 606. ASC 606 provides a single, principles-based five-step model to be applied to all contracts with customers, and generally provides for the recognition of revenue in an amount that reflects the considerations to which the Company expects to be entitled when control over the promised goods or services are transferred to the customer. ASC 606 also enhances disclosures about revenue, provides additional guidance for transactions that were not previously addressed comprehensively and improves guidance for multiple-element arrangements. In addition, ASC 606 includes Subtopic 340-40, Other Assets and Deferred Costs - Contracts with Customers, which requires the deferral of incremental costs of obtaining a contract with a customer. The Company adopted ASC 606 utilizing the full retrospective method of transition, which requires the Company to restate certain previously reported results, including the impact on the provision for income taxes. Adoption of the new standard resulted in changes to the Company’s accounting policies for revenue recognition and related cost of goods sold, as well as the capitalization and deferral of certain commission expenses, and a cumulative increase to retained earnings of approximately $23.9 million and $17.1 million as of December 31, 2016 and December 30, 2017, respectively. The areas impacted by ASC 606 include: (i) the acceleration of certain revenue from product sales to distributors that was previously deferred under the “sell-through” method; (ii) the acceleration of revenue related to certain software/parameter sales; (iii) the aggregation of all contract modifications occurring prior to the beginning of the earliest period presented; (iv) the acceleration of costs related to equipment for which control transfers up-front under certain contracts, the future consideration for which will now be treated as an optional purchase; (v) the capitalization and amortization of certain contract-related costs that were previously expensed when incurred; and (vi) the corresponding income tax effects related to these adjustments. The Company applied the new standard using certain practical expedients, including: (i) excluding disclosures of transaction prices allocated to remaining performance obligations when the Company expects to recognize such revenue for all periods prior to the date of initial application of ASC 606; (ii) not adjusting the promised amount of consideration for the effects of a significant financing component when the Company expects, at contract inception, that the period between the Company’s transfer of a promised product or service to a customer and when the customer pays for that product or service will be one year or less; (iii) expensing costs as incurred for costs to obtain a contract when the amortization period would have been one year or less; (iv) not recasting revenue for contracts that begin and end in the same fiscal year; and (v) not assessing whether promised goods or services are performance obligations if they are immaterial in the context of the contract with the customer. Pursuant to the full retrospective method of adoption under ASC 606, the Company has adjusted certain amounts previously reported in its consolidated financial statements. The reconciliations below reflect the adoption of ASC 606, the adoption of ASU 2016-16 and certain other immaterial reclassifications (in thousands, except per share amounts):

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, (ASU 2016-01). The new standard requires that (i) all equity investments, other than equity-method investments, in unconsolidated entities generally be measured at fair value, and (ii) changes in fair value due to instrument-specific credit risk be recognized separately in other comprehensive income when the fair value option has been elected for financial liabilities. ASU 2016-01 is effective for annual and interim fiscal reporting periods beginning after December 15, 2017. The Company adopted this standard during the year ended December 29, 2018 and such adoption did not have a material impact on the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements In August 2018, the FASB issued 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 (ASU 2018-15). The new standard aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the expected impact of this standard, but does not expect it to have a material impact on its consolidated financial statements upon adoption. In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements (ASU 2018-09). This new standard amends, clarifies, corrects errors in and makes minor improvements to the ASC. The transition and effective date guidance is based on the facts and circumstances of each amendment. Some of the amendments of ASU 2018-09 do not require transition guidance and will be effective upon issuance. However, many of the amendments of ASU 2018-09 that contain transition guidance are effective for the Company for annual periods beginning after December 15, 2018. The Company is currently evaluating the expected impact of this standard, but does not expect it to have a material impact on its consolidated financial statements upon adoption. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (ASU 2018-02). The new standard allows a reclassification from accumulated other comprehensive income to retained earnings for the tax effects resulting from “An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018” (the Reconciliation Act) that are stranded in accumulated other comprehensive income. The new standard also requires certain disclosures about stranded tax effects. The new standard, however, does not change the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations. ASU 2018-02 is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. ASU 2018-02 must be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Reconciliation Act is recognized. The Company is currently evaluating the expected impact of this standard, but does not expect it to have a material impact on its consolidated financial statements upon adoption. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). The new standard requires entities to use a current expected credit loss model, which is a new impairment model based on expected losses rather than incurred losses. Under this model, an entity would recognize an impairment allowance equal to its current estimate of all contractual cash flows that the entity does not expect to collect. The entity’s estimate would consider relevant information about past events, current conditions, and reasonable and supportable forecasts. ASU 2016-13 is effective for annual and interim fiscal reporting periods beginning after December 15, 2019, with early adoption permitted for annual reporting periods beginning after December 15, 2018. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, (ASU 2018-19). The new standard clarifies that receivables arising from operating leases are accounted for using lease guidance and not as financial instruments. This standard should be applied on either a prospective transition or modified-retrospective approach depending on the subtopic. ASU 2018-19 is effective for annual periods beginning after December 15, 2019, and interim periods therein. Early adoption is permitted for annual periods beginning after December 15, 2018 and interim periods therein. The Company is currently evaluating the expected impact of this standard, but does not expect it to have a material impact on its consolidated financial statements upon adoption. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (ASU 2016-02). ASU 2016-02 replaces the existing lease guidance under ASC 840 with ASC 842, which among other things, requires lessees to recognize most leases on their balance sheets but continue to recognize lease expenses in their statement of operations in a manner similar to current practice. ASU 2016-02 states that a lessee will recognize a lease liability for the obligation to make lease payments and a right-of-use asset for the right to use the underlying asset for the lease term. Expense related to leases determined to be operating leases will be recognized on a straight-line basis, while those determined to be financing leases will be recognized following a front-loaded expense profile in which interest and amortization are presented separately in the statement of operations. ASU 2016-02 is effective for annual and interim fiscal reporting periods beginning after December 15, 2018, and early application is permitted. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases (ASU 2018-10). ASU 2018-10 provides clarification on the rate implicit in the lease, impairment of the net investment in the lease, lessee reassessment of lease classification, lessor reassessment of lease term and purchase options, variable payments that depend on an index or rate and certain transition adjustments. ASU 2018-10 is effective when ASU 2016-02 is adopted. The FASB also issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements (ASU 2018-11) in July 2018. ASU 2018-11 provides a transition option and a practical expedient for lessors to aid in cost reductions and complexity of implementing the new standard. Entities that elect this transition option still adopt the new leases standard using the modified retrospective transition method required by the standard, but they recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption rather than in the earliest period presented. The optional practical expedient allows lessors to elect, by class of underlying asset, to not separate non-lease components from the associated lease components if the non-lease components otherwise would be accounted for in accordance with ASC 606 and both of the following criteria are met: (1) the lease component and the associated non-lease components have the same timing and pattern of transfer and(2) the lease component, if accounted for separately, would be classified as an operating lease. ASU 2018-11 is also effective is effective when ASU 2016-02 is adopted. In December 2018, the FASB issued ASU 2018-20, Leases (Topic 842): Narrow- Scope Improvements for Lessors (ASU 2018-20). The new standard is an amendment to help lessors apply the lease standard ASU No. 2016-02, Leases (Topic 842) (ASU 2016-02). It allows lessors to make an accounting policy election to exclude the sales taxes and other similar taxes on a specific lease from the measurement of lease revenue and associated expenses. ASU 2018-20 is effective when ASU 2016-02 is adopted. The Company is continuing to evaluate the expected impact of ASC 842 on its consolidated financial statements, but anticipates that, among other things, the required recognition by a lessee of a lease liability and related right-of-use asset for operating leases will increase both the assets and liabilities recognized and reported on its balance sheet as of the adoption date. In addition, ASC 842 will also change the classification of certain leases for which the Company is the lessor, resulting in the acceleration of revenue under certain contracts, as well as the immediate expensing of certain costs that are currently deferred and expensed over the life of the lease. The Company is also continuing to evaluate the available practical expedients and its adoption method for this new standard. The Company anticipates that its internal control framework will not materially change upon adoption of ASC 842, but certain existing internal controls will be modified and augmented, as necessary, effective as of December 30, 2018. As the Company implements this new standard, it will also continue to develop additional internal controls, as required, to ensure that it adequately evaluates its contracts under the new lease standard and accurately reports its current and any required prior-period operating results, as well as all required disclosures. When adopted, the Company expects to recognize a lease asset and incremental lease liability related to the lessee provisions under ASC 842 between $19.0 million to $24.0 million and a cumulative decrease to retained earnings related to the lessor provisions under ASC 842 of between $16.0 million to $26.0 million as of December 29, 2018.
