The Company’s fiscal year is a 52 or 53-week period ending on the last Sunday in the month of June. The Company’s 2019 fiscal year was a 53-week fiscal year. The Company's 2018 and 2017 fiscal years were 52-week fiscal years. The Company’s 2020 fiscal year will be a 52-week fiscal year.

The Company revised net cash provided by operating activities and net cash provided by (used in) financing activities for the years ended June 24, 2018 and June 25, 2017 to correct the presentation of tax withholding for stock option exercises. The Company increased net cash provided by operating activities by $6.2 million and $4.6 million and decreased net cash provided by (used in) financing activities by the same amounts for the years ended June 24, 2018 and June 25, 2017, respectively. The Company concluded these errors were not material individually or in the aggregate to any of the periods impacted.

Additionally, the Company corrected the classification of certain money market funds which were previously disclosed as non-U.S. certificates of deposits within cash equivalents in Note 9, "Fair Value of Financial Instruments." As a result, non-U.S. certificates of deposit decreased by $40.9 million and money market funds increased by the same amount as of June 24, 2018. Total cash equivalents was not affected.

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and the disclosure of contingent assets and liabilities. The Company evaluates its estimates on an ongoing basis, including those related to revenue recognition, product warranty obligations, valuation of inventories, tax related contingencies, valuation of stock-based compensation, valuation of long-lived and intangible assets, other contingencies and litigation, among others. The Company generally bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from those estimates.

U.S. GAAP requires segmentation based on an entity’s internal organization and reporting of revenue and operating income based upon internal accounting methods commonly referred to as the “management approach.” Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker (CODM), or decision making group, in deciding how to allocate resources and in assessing performance. The Company’s CODM is its Chief Executive Officer. The Company has determined that it currently has two operating and reportable segments.

Cash and cash equivalents consist of unrestricted cash accounts and highly liquid investments with an original maturity of three months or less when purchased. Cash and cash equivalents are stated at cost, which approximates fair value. The Company holds cash and cash equivalents at several major financial institutions, which often exceed insurance limits set by the Federal Deposit Insurance Corporation (FDIC). The Company has not historically experienced any losses due to such concentration of credit risk.

When the fair value of an investment declines below its original cost, the Company considers all available evidence to evaluate whether the decline is other-than-temporary. Among other things, the Company considers the duration and extent of the decline and economic factors influencing the capital markets. For the fiscal years ended June 30, 2019, June 24, 2018, and June 25, 2017, the Company had no other-than-temporary declines below the cost basis of its investments. The Company utilizes specific identification in computing realized gains and losses on the sale of investments. Realized gains and losses on the sale of investments are reported in non-operating expense (income).

Other long-term investments consist of the Company's approximately 16% common stock ownership interest in Lextar Electronics Corporation (Lextar), which the Company acquired in December 2014. The Company currently utilizes the fair value option in accounting for its investment in Lextar.

Inventories are stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out (FIFO) method or an average cost method. The Company writes down its inventory balances for estimates of excess and obsolete amounts. These write-downs are recognized as a component of cost of revenue. At the point of the write-down, a new lower cost basis for that inventory is established, and any subsequent improvements in facts and circumstances do not result in the restoration or increase in that newly established lower cost basis. If that inventory is subsequently sold, the sale is recorded at the actual selling price and the related cost of revenue is recorded at the new lower cost basis.

Property and equipment are stated at cost and depreciated on a straight-line basis over the assets’ estimated useful lives. Leasehold improvements are amortized over the lesser of the asset life or the term of the related lease. In general, the Company’s policy for useful lives is as follows:

Expenditures for repairs and maintenance are charged to expense as incurred. The costs for major renewals and improvements are capitalized and depreciated over their estimated useful lives. The cost and related accumulated depreciation of the assets are removed from the accounts upon disposition and any resulting gain or loss is reflected in operating income.

The Company recognizes the assets acquired and liabilities assumed in business combinations at their respective fair values at the date of acquisition, with any excess purchase price recognized as goodwill. Valuation of intangible assets entails significant estimates and assumptions including, but not limited to, estimating future cash flows from product revenue, developing appropriate discount rates, continuation of customer relationships and renewal of customer contracts, and approximating the useful lives of the intangible assets acquired.

The Company recognizes goodwill as an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. The Company tests goodwill for impairment at least annually as of the first day of the fiscal fourth quarter, or when indications of potential impairment exist. The Company monitors for the existence of potential impairment indicators throughout the fiscal year.

The Company conducts impairment testing for goodwill at the reporting unit level. Reporting units may be operating segments as a whole, or an operation one level below an operating segment, referred to as a component. The Company has determined that its reporting units are its two operating and reportable segments.

The Company may initiate goodwill impairment testing by considering qualitative factors to determine whether it is more likely than not that a reportable segment’s carrying value is greater than its fair value. Such factors may include the following, among others: a significant decline in the reporting unit’s expected future cash flows; a sustained, significant decline in the Company’s stock price and market capitalization; a significant adverse change in legal factors or in the business climate; unanticipated competition; and slower growth rates; as well as changes in management, key personnel, strategy and customers. If the Company's qualitative assessment indicates it is more likely than not that the estimated fair value of a reporting unit exceeds its carrying value, no further analysis is required and goodwill is not impaired. Otherwise, the Company performs a quantitative goodwill impairment test to determine if goodwill is impaired. The quantitative test compares the fair value of a reporting unit with its carrying amount, including goodwill.

If the fair value of the reportable segment exceeds the carrying value of the net assets associated with the segment, goodwill is not considered impaired. If the carrying value of the net assets associated with the reportable segment exceeds the fair value of the segment, the Company recognizes an impairment loss in an amount equal to the excess, not to exceed the carrying value of the reportable segment's goodwill. Once an impairment loss is recognized, the adjusted carrying value of the goodwill becomes the new accounting basis of the goodwill for the reporting unit. The Company derives a reportable segment’s fair value through a combination of the market approach (guideline transaction method and guideline public company method) and the income approach (a discounted cash flow analysis). The income approach utilizes a discount rate from the capital asset pricing model. If all reportable segments are analyzed, their respective fair values are reconciled back to the Company’s consolidated market capitalization.

Patent rights reflect costs incurred by the Company in applying for and maintaining patents owned by the Company and costs incurred in purchasing patents and related rights from third parties. Licensing rights reflect costs incurred by the Company in acquiring licenses under patents owned by others. The Company amortizes both on a straight-line basis over the expected useful life of the associated patent rights, which is generally the lesser of 20 years from the date of the patent application or the license period. Royalties payable under licenses for patents owned by others are generally expensed as incurred. The Company reviews its capitalized patent portfolio and recognizes impairment charges when circumstances warrant, such as when patents have been abandoned or are no longer being pursued.

The Company reviews long-lived assets such as property and equipment for impairment based on changes in circumstances that indicate their carrying amounts may not be recoverable. In making these determinations, the Company uses certain assumptions, including but not limited to: (1) estimations of the fair market value of the assets and (2) estimations of future cash flows expected to be generated by these assets, which are based on additional assumptions such as asset utilization, length of service the asset will be used in the Company’s operations and estimated salvage values.

The Company recognizes contingent liabilities when it is probable that an asset has been impaired or a liability has been incurred at the date of the financial statements and the amount of the loss can be reasonably estimated. Disclosure in the notes to the financial statements is required for loss contingencies that do not meet both these conditions if there is a reasonable possibility that a loss may have been incurred. See Note 16, “Commitments and Contingencies,” for a discussion of loss contingencies in connection with pending and threatened litigation. The Company expenses as incurred the costs of defending legal claims against the Company.

Revenue is recognized when control of a good or service promised in a contract (i.e., performance obligation) is transferred to a customer. Control is obtained when a customer has the ability to direct the use of and obtain substantially all of the remaining benefits from that good or service. Substantially all of the Company's revenue is derived from product sales. Revenue is recognized at a point in time based on the Company’s evaluation of when the customer obtains control of the products, and all performance obligations under the terms of the contract are satisfied. If customer acceptance clauses are present and it cannot be objectively determined that control has been transferred based on the contract and shipping terms, revenue is only recorded when customer acceptance is received and all performance obligations have been satisfied. Sales of products typically do not include more than one performance obligation.

A substantial portion of the Company’s products are sold through distributors. Distributors stock inventory and sell the Company’s products to their own customer base, which may include: value added resellers; manufacturers who incorporate the Company’s products into their own manufactured goods; or ultimate end users of the Company’s products. The Company recognizes revenue upon shipment of its products to its distributors. This arrangement is often referred to as a “sell-in” or “point-of-purchase” model as opposed to a “sell-through” or “point-of-sale” model, where revenue is deferred and not recognized until the distributor sells the product through to their customer.

purchase commitments. If a master supply, distributor or other similar agreement is not in place with a customer, the Company considers a purchase order, which is governed by the Company’s standard terms and conditions, to be the contract governing the relationship with that customer.

Pricing terms are negotiated independently on a stand-alone basis. Revenue is measured based on the amount of net consideration to which the Company expects to be entitled to receive in exchange for products or services. Variable consideration is recognized as a reduction of net revenue with a corresponding reserve at the time of revenue recognition, and consists primarily of sales incentives or rebates, price concessions and return allowances. Variable consideration is estimated based on contractual terms, historical analysis of customer purchase volumes, or historical analysis using specific data for the type of consideration being assessed. The Company offers product warranties and establishes liabilities for estimated warranty costs based upon historical experience and specific warranty provisions. Warranty liability estimates are included in cost of revenue in the Company’s consolidated statements of operations, and further detail is presented in Note 16, "Commitments and Contingencies."

Certain of the Company’s distributors are provided limited rights that allow them to return a portion of inventory (product exchange rights or stock rotation rights) and receive credits for changes in selling prices (price protection rights) or customer pricing arrangements under the Company’s “ship and debit” program or other targeted sales incentives. These estimates are calculated based upon historical experience, product shipment analysis, current economic conditions, on-hand inventory at the distributor, and customer contractual arrangements. The Company believes that it can reasonably and reliably estimate the allowance for distributor credits at the time of sale. Accordingly, estimates for these rights are recognized at the time of sale as a reduction of product revenue and as a contract liability.

From time to time, the Company will issue a new price book for its products, and provide a credit to certain distributors for inventory quantities on hand if required by the Company’s agreement with the distributor. This practice is known as price protection. These credits are applied against the reserve that the Company establishes upon initial shipment of product to the distributor.

Under the ship and debit program, products are sold to distributors at negotiated prices and the distributors are required to pay for the products purchased within the Company’s standard commercial terms. Subsequent to the initial product purchase, a distributor may request a price allowance for a particular part number(s) for certain target customers, prior to the distributor reselling the particular part to that customer. If the Company approves an allowance and the distributor resells the product to the target customer, the Company credits the distributor according to the allowance the Company approved. These credits are applied against the reserve that the Company establishes upon initial shipment of product to the distributor.

In addition, the Company runs sales incentive programs with certain distributors, such as product rebates. The Company recognizes these incentives at the time they are offered to customers and records a credit to their account with an offsetting expense as either a reduction to revenue, increase to cost of revenue, or marketing expense depending on the type of sales incentive.

From time to time, the Company may enter into licensing arrangements related to its intellectual property. Revenue from licensing arrangements is recognized when earned and estimable. The timing of revenue recognition is dependent on the terms of each license agreement. Generally, the Company will recognize non-refundable upfront licensing fees related to patent licenses immediately upon receipt of the funds if the Company has no significant future obligations to perform under the arrangement. However, the Company will defer recognition for licensing fees where the Company has significant future performance requirements, the fee is not fixed (such as royalties earned as a percentage of future revenue), or the fees are otherwise contingent.

For product revenue, the Company typically invoices its customers at the time of shipment for the sales order value of products shipped. Accounts receivable are recognized at the invoiced amount and are not subject to any interest or finance charges. The Company does not have any off-balance sheet credit exposure related to any of its customers.

The Company evaluates the collectability of accounts receivable based on a combination of factors. In cases where the Company becomes aware of circumstances that may impair a specific customer’s ability to meet its financial obligations subsequent to the original sale, the Company will recognize an allowance against amounts due, and thereby reduce the net recognized receivable to the amount the Company reasonably believes will be collected. For all other customers, the Company recognizes an allowance for doubtful accounts based on the length of time the receivables are past due and consideration of other factors such as industry conditions, the current business environment and the Company’s historical experience.

The Company expenses the costs of producing advertisements at the time production occurs and expenses the cost of communicating the advertising in the period in which the advertising is used. Advertising costs are included in sales, general and administrative expenses in the consolidated statements of operations and amounted to approximately $4.2 million, $3.9 million, and $5.3 million for the years ended June 30, 2019, June 24, 2018 and June 25, 2017, respectively.

Basic loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding for the applicable period. Diluted loss per share is determined in the same manner as basic loss per share except that the number of shares is increased to assume exercise of potentially dilutive stock options, nonvested restricted stock and contingently issuable shares using the treasury stock method, unless the effect of such increases would be anti-dilutive. Under the treasury stock method, the amount the employee must pay for exercising stock options, the amount of compensation cost for future service that the Company has not yet recognized, and the amount of tax benefits that would be recognized in additional paid-in capital when the award becomes deductible are assumed to be used to repurchase shares.

Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets are recognized for deductible temporary differences, along with net operating loss carryforwards and credit carryforwards, if it is more likely than not that the tax benefits will be realized. To the extent a deferred tax asset cannot be recognized under the preceding criteria, valuation allowances are established. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled.

Taxes payable which are not based on income are accrued ratably over the period to which they apply. For example, payroll taxes are accrued each period end based upon the amount of payroll taxes that are owed as of that date; whereas taxes such as property taxes and franchise taxes are accrued over the fiscal year to which they apply if paid at the end of a period, or they are amortized ratably over the fiscal year if they are paid in advance.

Foreign currency translation adjustments are recognized in other comprehensive (loss) income in the consolidated statements of comprehensive loss for changes between the foreign subsidiaries’ functional currency and the United States (U.S.) dollar. Foreign currency translation gains and losses are included in the Company’s equity account balance of accumulated other comprehensive income, net of taxes in the consolidated balance sheets until such time that the subsidiaries are either sold or substantially liquidated.

In June 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-07: Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. The ASU applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor's own operations by issuing share-based payment awards. The Company early adopted this standard in the second quarter of fiscal 2019. There was no material impact upon adoption of this standard.

In August 2018, the FASB issued ASU 2018-13: Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The ASU modifies the disclosure requirements required for fair value measurements. The Company early adopted this standard in the first quarter of fiscal 2019.

In August 2018, the FASB issued ASU 2018-15: Intangibles - Goodwill and Other - Internal-Use Software (Topic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. The ASU allows companies to capitalize implementation costs incurred in a hosting arrangement that is a service contract over the term of the hosting arrangement, including periods covered by renewal options that are reasonably certain to be exercised. The Company early adopted this standard in the first quarter of fiscal 2019. There was no significant impact on the financial statements.

In May 2014, the FASB issued ASU No. 2014-09: Revenue from Contracts with Customers (Topic 606) (ASC 606). The FASB has subsequently issued multiple ASUs that amend and clarify the guidance in ASC 606. The ASU establishes a principles-based approach for accounting for revenue arising from contracts with customers and supersedes existing revenue recognition guidance. The ASU provides that an entity should apply a five-step approach for recognizing revenue, including (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation. Also, the entity must provide various disclosures concerning the nature, amount and timing of revenue and cash flows arising from contracts with customers. The Company adopted this standard on June 25, 2018.

The cumulative effect of the adoption recorded to beginning accumulated deficit as of June 25, 2018 was $10.3 million. The Company did not recognize a discrete tax impact related to the opening deferred tax balance as of June 25, 2018 due to a full U.S. valuation allowance. The Company recorded $1.6 million less revenue for the fiscal year ended June 30, 2019 as a result of the adoption and expects the ongoing effect to be immaterial to the consolidated financial statements. See Note 4, "Revenue Recognition," for discussion of the impacted financial statement line items.

In February 2016, the FASB issued ASU No. 2016-02: Leases (Topic 842) (ASC 842), and ASU 2018-10: Codification Improvements to ASC 842, Leases. These ASU’s require that a lessee recognize in its statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term and will require enhanced disclosures about an entity’s leasing arrangements. The Company will adopt this standard on July 1, 2019, under the modified retrospective transition approach with the cumulative effect of application recognized at the effective date, without reclassification of previous financial statements. Upon adoption, the Company plans to elect the transition package of practical expedients that allows it to not reassess (1) whether any expired or existing contracts are leases, or contain leases, (2) the lease classification for any expired or existing leases, and (3) initial direct costs for any existing leases. Further, upon implementation of the new guidance, the Company intends to elect the practical expedient to not separate lease and non-lease components for all leases and account for the combined lease and non-lease components as a single lease component. The Company also plans to make an accounting policy election to exclude leases with an initial term of 12 months or less from the consolidated balance sheets.

The Company expects the adoption of this standard will result in the inclusion of a significant component of the Company’s future minimum lease obligations, as disclosed in Note 16, “Commitments and Contingencies” on its consolidated balance sheets, as right-of-use assets and lease liabilities with no material impact to its consolidated statements of operations and consolidated statements of comprehensive loss. Any new lease arrangements or material modifications entered into subsequent to the adoption date will be accounted for in accordance with the new standard. The Company is continuing to assess the potential impacts of the ASC 842. The Company anticipates disclosing additional information, as necessary, to comply with the new leasing standard.
