Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Revenue Recognition The Company derives revenues primarily from sales of its networking equipment, with the remaining revenue generated from service fees relating to maintenance contracts, professional services, and training for the products. The Company recognizes revenues when control of promised goods or services is transferred to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. See Note 3. Revenues, for further discussion. Cash, Cash Equivalents and Marketable Securities The Company considers highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents. Marketable securities are recorded in “Prepaid expense and other current assets” in the accompanying consolidated balance sheet as these are publicly-traded equity securities with maturities of greater than three months, but less than one year at the balance sheet date. Marketable securities are classified as available-for-sale and reported at fair value with unrealized gains and losses included, net of tax, in accumulated other comprehensive loss, a component of stockholders’ equity. Realized gains and losses and declines in the value of available-for-sale securities determined to be other than temporary are included in other income (expense), net. The cost of securities sold is determined based on the specific identification method. Allowance for Product Returns The Company provides an allowance for product returns based on its historical returns, analysis of credit memo data and its return policies. The allowance includes the estimates for product allowances from end customers as well as stock rotations and other returns from the Company’s stocking distributors. The allowance for product returns is a reduction of accounts receivable. If the historical data that the Company uses to calculate the estimated product returns and allowances does not properly reflect actual levels of product returns, these estimates will be revised, resulting in an impact on net revenue. The allowance for product returns estimate is also impacted by the timing of the actual product return from the customer. Allowance for Doubtful Accounts The Company maintains an allowance for doubtful accounts which reflects its best estimate of potentially uncollectible trade receivables. The allowance consists of both specific and general reserves. The Company continually monitors and evaluates the collectability of its trade receivables based on a combination of factors. It records specific allowances for bad debts in general and administrative expense when it becomes aware of a specific customer’s inability to meet its financial obligation to the Company, such as in the case of bankruptcy filings or deterioration of financial position. Estimates are used in determining the allowances for all other customers based on factors such as current trends in the length of time the receivables are past due and historical collection experience. The Company mitigates some collection risk by requiring most of its customers in the Asia-Pacific region, excluding Japan and Australia, to pay cash in advance or secure letters of credit when placing an order with the Company. Inventories The Company values its inventory at lower of cost or net realizable value. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis. The Company has established inventory allowances when conditions exist that suggest that inventory is obsolete or may be in excess of anticipated demand based upon assumptions about future demand. At the point of the loss recognition, a new, lower-cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Previously written down or obsolete inventory subsequently sold has not had a material impact on gross margin for any of the periods presented. Long-Lived Assets Long-lived assets include (a) property and equipment, (b) goodwill and intangible assets, and (c) other assets. Property and equipment and definite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets or asset groups may not be recoverable. If such facts and circumstances exist, the Company assesses the recoverability of these assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairments, if any, are based on the excess of the carrying amount over the fair value of those assets. (a) Property and Equipment, Net Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the assets. Estimated useful lives of one to four years are used for computer equipment and software. Estimated useful lives of three to seven years are used for office equipment, furniture and fixtures. Depreciation and amortization of leasehold improvements is computed using the lesser of the useful life or lease terms (ranging from two to ten years). (b) Goodwill and Intangible Assets Goodwill and intangible assets are generated as a result of business combinations and are comprised of, among other things, developed technology, customer relationships, trade names, and licensing agreements. The Company reevaluates the estimated remaining useful life of acquired definite-lived intangible assets whenever events or changes in circumstances indicate a revision to the remaining period of amortization might be necessary. The carrying amounts of these assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. Goodwill is calculated as the excess of the purchase price over the fair value of net tangible and identifiable intangible assets acquired. Goodwill is not amortized, but rather is tested for impairment at least annually or more frequently if indicators of impairment are present. The Company performs its annual goodwill impairment analysis as of the first day of the fourth quarter of each year. The Company adopted ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment in fiscal 2018, which eliminated step two from the goodwill impairment test. In assessing impairment on goodwill, the Company bypasses the qualitative assessment and proceed directly to performing the quantitative evaluation of the fair value of the reporting unit, to compare against the carrying value of the reporting unit. A goodwill impairment charge is recognized for the amount by which the reporting unit’s fair value is less than its carrying value. Any loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Based on the results of the goodwill impairment analyses, the Company determined that no impairment charge needed to be recorded for any periods presented. (c) Other Assets Other assets consist primarily of service parts and long-term deposits. The Company holds service parts to support customers who have purchased service contracts with a hardware replacement element, as well as to support its warranty program. The Company reduces the carrying value of service parts to net realizable value based on expected quantities needed to satisfy contractual service requirements of customers. Business Combinations The Company applies the acquisition method of accounting for business combinations. Under this method of accounting, all assets acquired and liabilities assumed are recorded at their respective fair values at the date of the acquisition. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, useful lives, among other items. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Market participants are assumed to be buyers and sellers in the principal (most advantageous) market for the asset or liability. Additionally, fair value measurements for an asset assume the highest and best use of that asset by market participants. As a result, the Company may be required to value the acquired assets at fair value measures that do not reflect its intended use of those assets. Use of different estimates and judgments could yield different results. Any excess of the purchase price over the fair value of the net assets acquired is recognized as goodwill. If the fair value of net assets acquired exceeds the fair value of the purchase price, a gain on bargain purchase is recognized within the consolidated statements of operations. Although the Company believes the assumptions and estimates it has made are reasonable and appropriate, they are based in part on historical experience and information that may be obtained from the management of the acquired company and are inherently uncertain. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill for facts and considerations that were known at the acquisition date. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded within the Company’s consolidated statements of operations. Deferred Revenue Deferred revenue represents amounts for (i) deferred maintenance and support revenue and (ii) other deferred revenue including professional services and training when the revenue recognition criteria have not been met. Product Warranties and Guarantees Networking products may contain undetected hardware or software errors when new products or new versions or updates of existing products are released to the marketplace. The majority of the Company’s hardware products are shipped with either a one-year warranty or a limited lifetime warranty, and software products receive a 90-day warranty for media only. Upon shipment of products to its customers, the Company estimates expenses for the cost to repair or replace products that may be returned under warranty and accrues a liability in cost of product revenue for this amount. The determination of the Company’s warranty requirements is based on actual historical experience with the product or product family, estimates of repair and replacement costs and any product warranty problems that are identified after shipment. The Company estimates and adjusts these accruals at each balance sheet date in accordance with changes in these factors. In the normal course of business to facilitate sales of its products, the Company indemnifies its resellers and end-user customers with respect to certain matters. The Company has agreed to hold the customer harmless against losses arising from a breach of intellectual property infringement or other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. It is not possible to estimate the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material impact on its operating results or financial position. Stock-based Compensation The Company recognizes compensation expense related to stock-based awards, including stock options, restricted stock units (“RSUs”) and employee stock purchases related to its 2014 Employee Stock Purchase Plan (the “2014 ESPP”), based on the estimated fair value of the award on the grant date, over the requisite service period. The Company accounts for forfeitures as they occur. The Company calculates the fair value of stock options and share purchase options under the 2014 ESPP using the Black-Scholes-Merton option valuation model. The fair value of RSUs is based on the closing stock price of the Company’s common stock on the grant date. The Company grants certain employees performance-based stock options and RSUs. The performance metrics include company-wide financial performance and/or market conditions. For awards that include performance conditions, no compensation cost is recognized until the performance goals are probable of being met, at which time the cumulative compensation expense from the service inception date would be recognized. For awards that contain market conditions, compensation expense is measured using a Monte Carlo simulation model and recognized over the derived service period based on the expected market performance as of the grant date. Advertising Advertising costs are expensed as incurred. Advertising expenses were $0.3 million, $0.5 million and $0.4 million in fiscal years 2019, 2018 and 2017 respectively. Income Taxes The Company accounts for income taxes utilizing the liability method. Deferred income taxes are recorded to reflect consequences on future years of differences between financial reporting and the tax basis of assets and liabilities measured using the enacted statutory tax rates and tax laws applicable to the periods in which differences are expected to affect taxable earnings. A valuation allowance is recognized to the extent that it is more likely than not that the tax benefits will not be realized. The Company accounts for uncertainty in income taxes using a two-step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that the Company anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes. For additional discussion, see Note 15. Income Taxes. Recently Issued Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases (Topic 842), which requires the identification of arrangements that should be accounted for as leases by lessees and lessors, and key disclosure information about leasing arrangements. In general, for lease arrangements exceeding a twelve-month term, these arrangements must now be recognized as assets and liabilities on the balance sheet of the lessee. Under Topic 842, a right-of-use asset (“ROU”) and lease obligation will be recorded for all leases, whether operating or financing, while the statement of operations will reflect lease expense for operating leases and amortization/interest expense for financing leases. The balance sheet amount recorded for existing leases at the date of adoption of Topic 842 must be calculated using the applicable incremental borrowing rate at the date of adoption. Topic 842 also required lessors to classify leases as a sales-type, direct financing or operating lease. A lease is a sales-type lease if any one of five criteria are met, each of which indicate that the lease, in effect, transfers control of the underlying asset to the lessee. If none of those five criteria are met, but two additional criteria are both met, indicating that the lessor has transferred substantially all of the risks and benefits to the lessee and a third party, the lease is a direct financing lease. All leases that are not sales-type or direct financing leases are operating leases. The Company believes that substantially all of its leases continue to be classified as operating leases. In addition, Topic 842 was subsequently amended by ASU No 2018-10, Codification Improvements; ASU 2018-11, Targeted Improvements; ASU 2018-20 Narrow Scope Improvements; and ASU 2019-01 Codification Improvements. This guidance will become effective for the Company and the Company will adopt the new standards beginning with its fiscal year 2020, beginning on July 1, 2019. Topic 842 is applied on the modified retrospective method, applying the new standard to all leases existing as of July 1, 2019. We expect to adopt the new standard using the effective date as our date of initial application. Consequently, financial information will not be updated, and disclosures required under the new standard will not be provided for dates and periods before July 1, 2019. The new standard provides a number of optional practical expedients in transition. The Company expects to elect the “package of practical expedients” which permits the Company not to reassess under the new standard our prior conclusions about lease identification, lease classification, and initial direct costs. The new standard also provides practical expedients for ongoing accounting. The Company also currently expects to elect the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, the Company will not recognize right-of-use assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. In addition, the Company currently does not expect to elect the practical expedient to separate lease and non-lease components for leases. The Company expects that these new standards will have a material impact to the Company’s financial position. The Company expects to recognize ROU assets and lease liabilities on the consolidated balance sheets with corresponding ROU assets of approximately $68 to $78 million and lease liabilities of approximately $82 to $92 million based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases. The Company does not expect that the adoption of Topic 842 will have a material effect on operating income (loss) and net cash flows, however it will impact the classification between cash flows from operations and cash flows from financing activities. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which is intended to allow companies to better align risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results by expanding and refining hedge accounting for both nonfinancial and financial risk components and aligning the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. In addition, in October 2018, the FASB issued ASU 2018-16, Derivatives and Hedging (Topic 815), which amends Topic 815 to add the overnight index swap (OIS) rate based on the secured overnight financing rate as a fifth U.S. benchmark interest rate. These standards are effective for interim and annual reporting periods beginning after December 15, 2018. The Company does not believe it will have a material impact on the Company’s financial statements upon adoption. This guidance is effective for the Company beginning with its fiscal year 2020, beginning on July 1, 2019. In addition, Topic 815 was subsequently amended by ASU 2019-04, Codification Improvements. In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220), this standard that allows the reclassification from AOCI to retained earnings for stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act ("Tax Reform Act"). The amount of the reclassification is the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances related to items remaining in AOCI. This standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period, for reporting periods for which financial statements have not yet been issued. The new standard is to be applied either in the period of adoption or retrospectively to each period (or periods) in which the effects of the change in the income tax rate in the Tax Reform Act are recognized. The Company does not believe it will have a material impact on the Company’s financial statements upon adoption. This guidance is effective for the Company beginning with its fiscal year 2020, beginning on July 1, 2019. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), which removes, modifies and adds various disclosure requirements around the topic in order to clarify and improve the cost-benefit nature of disclosures. For example, disclosures around transfers between fair value hierarchy levels will be removed and further detail around changes in unrealized gains and losses for the period and unobservable inputs determining Level 3 fair value measurements will be added. This standard is effective for interim and annual reporting periods beginning after December 15, 2019, and early adoption is permitted. The Company is currently evaluating the impact the new standard will have on its consolidated financial statements. This guidance is effective for the Company beginning with its fiscal year 2021, beginning on July 1, 2020. In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40), which aligns the requirements for capitalizing implementation costs incurred in a service contract hosting arrangement with those of developing or obtaining internal-use software. This standard is effective for interim and annual reporting periods beginning after December 15, 2019, and early adoption is permitted. The Company is currently evaluating the impact the new standard will have on its consolidated financial statements. This guidance is effective for the Company beginning with its fiscal year 2021, beginning on July 1, 2020. Recently Adopted Accounting Pronouncements In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, which provides guidance for the recognition, measurement, presentation, and disclosure of financial assets and liabilities. The guidance was adopted effective July 1, 2018 and the Company reclassified a $0.5 million unrealized gain, net of tax, related to its available-for-sale investments from accumulated other comprehensive loss to accumulated deficit as a cumulative-effect adjustment in the accompanying consolidated balance sheets. Future changes in fair value will be included in earnings in each period. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments to provide guidance on the classification of eight cash flow issues in order to reduce diversity in practice. The Company adopted the new guidance effective July 1, 2018. The amendments in this update have been applied on a retrospective transition method to each period presented. The adoption of this guidance did not have a material effect on the Company’s presentation of cash flows. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740) - Intra-Entity Transfers of Assets Other Than Inventory, which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Historically GAAP had prohibited the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold outside the consolidated group. The new guidance is effective for interim and annual reporting periods beginning after December 15, 2017. The Company adopted ASU 2016-16 effective July 1, 2018 on a modified retrospective basis. The adoption of this guidance did not have a material effect on the Company’s financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, which amends the scope of modification accounting for share-based payment arrangements and provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under Topic 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The Company adopted this guidance effective July 1, 2018, on a prospective basis. The adoption of this guidance did not have a material effect on the Company’s financial statements.
