Summary of Significant Accounting Policies |
Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The Company has evaluated events occurring subsequent to December 28, 2019, through the filing date of this Annual Report on Form 10-K and concluded that there were no events that required recognition and disclosures, other than those discussed elsewhere in the notes hereto. Certain prior period amounts have been reclassified to conform to the current period’s presentation.
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of the Company. All intercompany balances and transactions have been eliminated in consolidation.
Fiscal Year | Fiscal Year The Company’s fiscal year is the 52- or 53-week period that ends on the Saturday closest to December 31. The 2019 and 2018 fiscal years ended on December 28, 2019 and December 29, 2018, respectively, and consisted of 52 weeks.
Use of Estimates | Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, net sales and expenses. Significant items subject to such estimates and assumptions include provisions for uncollectible receivables and sales returns, warranty liability, valuation of inventories, fair value of financial instruments, useful lives and impairment of property and equipment, inputs used to value stock-based compensation and convertible debt instruments and the realization of deferred tax assets. Actual results may differ from these estimates.
Revenue Recognition | Revenue Recognition Revenue is recognized when control is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods and services. Revenue recognition is evaluated through the five steps outlined within the guidance. Substantially all of the Company’s net sales relate to products sold at a point in time through ship-and-bill performance obligations. At contract inception, an assessment of the goods and services promised in the contracts with customers is performed and a performance obligation is identified for each distinct promise to transfer to the customer a good or service (or bundle of goods or services). To identify the performance obligations, the Company considers all of the goods or services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices. Contracts with customers are comprised of customer purchase orders, invoices (including the Company’s standard terms and conditions) and written contracts. Performance Obligations Net sales and related cost of sales are primarily the result of promises to transfer products to customers. For performance obligations related to substantially all of the ship-and-bill products, control transfers at a point in time when title transfers upon shipment of the product to the customer, and for some sales, control transfers when title is transferred at time of receipt by the customer. Once a product has shipped or has been delivered, the customer is able to direct the use of, and obtain substantially all of the remaining benefits from, the asset. The Company considers control to have transferred upon shipment or delivery, because the Company has a present right to payment at that time, the customer has legal title to the asset, the Company has transferred physical possession of the asset, and the customer has the significant risks and rewards of ownership of the asset. Amounts billed to its customers for shipping and handling are recorded in net sales. Shipping and handling costs incurred by the Company are included in cost of sales in the accompanying consolidated statements of operations. Significant Payment Terms For ship-and-bill type contracts with customers, the invoice states the final terms of the sale, including the description, quantity, and price of each product purchased. Payment terms are typically due within 30 days after delivery but, in limited instances, can range up to 60 days after delivery. Accordingly, the Company’s contracts with customers do not include a significant financing component. Variable Consideration Customers are generally allowed limited rights of return for up to 30 days, except for sales of excess component inventories, which contain no right-of-return privileges. Product returns give rise to variable consideration that decreases the transaction price. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the anticipated performance and all information (historical, current and forecasted) that is reasonably available. Returns for products sold are estimated using the expected value method and are recorded as a reduction in reported revenues at the time of sale based upon historical product return experience and is adjusted for known trends to arrive at the amount of consideration to which the Company expects to receive. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Warranties The Company offers standard product warranties generally ranging from one to three years to its memory subsystem products customers, depending on the negotiated terms of any purchase agreements, and has no other post-shipment obligations or separately priced extended warranty or product maintenance contracts. These warranties require the Company to repair or replace defective product returned to the Company during the warranty period at no cost to the customer. Warranties are not offered on sales of component products. The Company records an estimate for warranty related costs at the time of sale based on its historical and estimated future product return rates and expected repair or replacement costs. Estimated future warranty costs are recorded in the period in which the sale is recorded and are included in cost of sales in the accompanying consolidated statements of operations.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents consist of cash and short-term investments with original maturities of three months or less.
Restricted Cash | Restricted Cash The Company’s restricted cash consists of cash to secure standby letters of credit (see Note 4).
Fair Value Measurements | Fair Value of Financial Instruments The Company accounts for certain assets and liabilities at fair value. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. The Company categorizes each of its fair value measurements in one of those three levels based on the lowest level input that is significant to the fair value measurement in its entirety.
| · |  | Level 1 – inputs are based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. An active market is defined as a market in which transactions for the assets or liabilities occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
| · |  | Level 2 – inputs are based on quoted prices of similar instruments in active markets, quoted prices for identical or similar instruments in market that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
| · |  | Level 3 – inputs are generally unobservable inputs for the asset or liability, which are typically based on management’s estimates of assumptions that market participants would use in pricing the assets and liabilities. The fair values are therefore determined using model-based techniques, including option pricing models and discounted cash flow models.
The Company’s financial instruments consist principally of cash and cash equivalents, restricted cash, a revolving line of credit, and convertible promissory notes. The Company considers the carrying values of cash and cash equivalents and restricted cash to approximate the fair value for these financial instruments based upon an evaluation of the underlying characteristics, market data and because of the short period of time between origination of the instruments and their expected realization. The Company estimates the fair values of its revolving line of credit and convertible promissory notes by using current applicable rates for similar instruments as of the balance sheet date and an assessment of its credit rating. The carrying value of the Company’s revolving line of credit at December 28, 2019 and December 29, 2018 approximates fair value because the Company’s interest rate yield is near current market rates for comparable debt instruments. The Company estimates the fair value of its convertible promissory notes by using a discounted cash flow analysis using borrowing rates available to the Company for debt instruments with similar terms and maturities. The Company has determined that the valuation of its convertible promissory notes is classified in Level 2 of the fair value hierarchy. The carrying value and estimated fair value of the senior secured convertible promissory note as of December 28, 2019 were $14.6 million and $11.7 million, respectively. The carrying value and estimated fair value of the senior secured convertible promissory note as of December 29, 2018 were $14.3 million and $11.7 million, respectively. The carrying value and estimated fair value of the unsecured convertible note were $2.0 million and $1.7 million as of December 29, 2018, respectively. There were no outstanding principal and accrued interest on the unsecured convertible note as of December 28, 2019.
Accounts Receivable, net | Accounts Receivable, net The Company extends credit to its customers. An allowance for doubtful accounts is maintained for estimated losses resulting from the inability of the Company’s customers to make required payments. The Company specifically analyzes the age of customer balances, historical bad debt experiences, customer creditworthiness and changes in customer payment terms when making estimates of the collectability of the Company’s accounts receivable balances. If the Company determines that the financial condition of any of its customers has deteriorated, whether due to customer specific or general economic issues, an increase in the allowance may be made. After all attempts to collect a receivable have failed, the receivable is written off.
Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents, and accounts receivable. The Company invests its cash equivalents primarily in money market mutual funds. Cash equivalents are maintained with high quality institutions, the composition and maturities of which are regularly monitored by management. At times, deposits held with financial institutions may exceed the amount of insurance provided by the Federal Deposit Insurance Corporation and the Securities Investor Protection Corporation. The Company’s accounts receivable are primarily derived from sales to original equipment manufacturers in the server, high-performance computing and communications markets, as well as from sales to storage customers, appliance customers, system builders and cloud and datacenter customers. The Company performs credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary, but generally requires no collateral. The Company believes the concentration of credit risk in its accounts receivables is moderated by its credit evaluation process, relatively short collection terms, a high level of credit worthiness of its customers (see Note 12), foreign credit insurance, and letters of credit issued in its favor. The allowance for credit losses is maintained, and such losses historically have not been significant and have been within management’s expectations.
Inventories | Inventories Inventories are valued at the lower of cost or the net realizable value. Cost is determined on an average cost basis which approximates actual cost on a first-in, first-out basis and includes raw materials, labor and manufacturing overhead. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company evaluates inventory balances for excess quantities and obsolescence on a regular basis by analyzing estimated demand, inventory on hand, sales levels and other information and reduce inventory balances to net realizable value for excess and obsolete inventory based on this analysis. At the point of the write-down 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.
Property and Equipment | Property and Equipment Property and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives, which generally range from three to seven years. Leasehold improvements are recorded at cost and amortized on a straight-line basis over the shorter of their estimated useful lives or the remaining lease term. Expenditures for repairs and maintenance are expensed as incurred. Upon retirement or sale, the cost and related accumulated depreciation and amortization of disposed assets are removed from the accounts and any resulting gain or loss is included in other income, net.
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company evaluates the recoverability of the carrying value of long-lived assets held and used by the Company in its operations for impairment on at least an annual basis or whenever events or changes in circumstances indicate that their carrying value may not be recoverable. When such factors and circumstances exist, the Company compares the projected undiscounted future net cash flows associated with the related asset or group of assets over their estimated useful lives against their respective carrying amount. These projected future cash flows may vary significantly over time as a result of increased competition, changes in technology, fluctuations in demand, consolidation of the Company’s customers and reductions in average sales prices. If the carrying value is determined not to be recoverable from future operating cash flows, the asset is deemed impaired and an impairment loss is recognized to the extent the carrying value exceeds the estimated fair value of the asset. The fair value of the asset or asset group is based on market value when available, or when unavailable, on discounted expected cash flows. The management believes there is no impairment of long-lived assets as of December 28, 2019 and December 29, 2018.
Leases | Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, accrued expenses and other current liabilities, and operating lease liabilities on its consolidated balance sheets. Finance leases are included in property and equipment, accrued expenses and other current liabilities, and other liabilities in its consolidated balance sheets. ROU assets represent the right of the Company to use an underlying asset for the lease term and lease liabilities represent the obligation of the Company to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The Company uses the implicit rate when readily determinable. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component. The Company does not present short-term leases on the balance sheet, as those leases have a lease term of twelve months or less at inception and do not contain purchase options or renewal terms that the Company is reasonably certain to exercise.
Stock-Based Compensation | Stock-Based Compensation Stock-based awards are comprised principally of stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”). Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as an expense over the requisite service period, which is the vesting period, on a straight-line basis, net of estimated forfeitures. The Company uses the Black-Scholes option pricing model to determine the grant date fair value of stock options. The model requires the Company to estimate the expected volatility and expected term of the stock options, which are highly complex and subjective variables. The expected volatility is based on the historical volatility of the Company’s common stock. The expected term is computed using the simplified method as the Company’s best estimate given its lack of actual exercise history. The risk-free rate selected to value any particular grant is based on the U.S. Treasury rate that corresponds to the expected term of the grant effective as of the date of the grant. The expected dividend assumption is based on the Company’s history and management’s expectation regarding dividend payouts. The grant-date fair value of restricted stock and RSUs equals the closing price of the Company’s common stock on the grant date. Prior to the adoption of FASB ASU No. 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07” or “Topic 718”) in the second quarter of 2018, the Company accounted for equity-based awards to non-employees in accordance with ASC Topic 505, Equity. All transactions in which goods or services were the consideration received for the issuance of equity instruments were accounted for based on the fair value of the consideration received or the fair value of the equity instrument issued, whichever was more reliably measurable. The measurement date used to determine the estimated fair value of the equity instrument issued was the earlier of the date on which the third-party performance was complete or the date on which it was probable that performance would occur. Upon the adoption of ASU No. 2018-07, the Company accounts for all stock-based awards in accordance with Topic 718.
Income Taxes | Income Taxes Deferred income tax assets and liabilities are recognized for temporary differences between the financial statement carrying amounts of assets and liabilities and the amounts that are reported in the income tax returns. Deferred taxes are evaluated for realization on a jurisdictional basis. The Company records valuation allowances to reduce deferred tax assets to the amount that is more likely than not to be realized. In making this assessment, management analyzes future taxable income, reversing temporary differences and ongoing tax planning strategies. Should a change in circumstances lead to a change in judgment about the realizability of deferred tax assets in future years, the Company will adjust related valuation allowances in the period that the change in circumstances occurs, along with a corresponding increase or charge to income. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of the Company’s position. The tax benefit recognized in the financial statements for a particular tax position is based on the largest benefit that is more likely than not to be realized. The amount of unrecognized tax benefits is adjusted as appropriate for changes in facts and circumstances, such as significant amendments to existing tax laws, new regulations or interpretations by the taxing authorities, new information obtained during a tax examination, or resolution of an examination. The Company recognizes both accrued interest and penalties associated with uncertain tax positions as a component of provision for income taxes in the consolidated statements of operations. The application of tax laws and regulations is subject to legal and factual interpretation, judgment and uncertainty. Tax laws and regulations may change as a result of changes in fiscal policy, changes in legislation, the 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 require the Company to record additional tax liabilities or to reduce previously recorded tax liabilities, as applicable.
Contingent Legal Expenses | Contingent Legal Expenses Contingent legal fees are expensed in the consolidated statements of operations in the period that the related revenues are recognized. In instances where there are no recoveries from potential infringers, no contingent legal fees are paid; however, the Company may be liable for certain out of pocket legal costs incurred pursuant to the underlying legal services agreement.
Research and Development Expenses | Research and Development Expenses Research and development expenditures are expensed in the period incurred.
Foreign Currency Remeasurement | Foreign Currency Remeasurement The functional currency of the Company’s foreign subsidiaries is the U.S. dollar. Local currency financial statements are remeasured into U.S. dollars at the exchange rate in effect as of the balance sheet date for monetary assets and liabilities and the historical exchange rate for nonmonetary assets and liabilities. Expenses are remeasured using the average exchange rate for the period, except items related to nonmonetary assets and liabilities, which are remeasured using historical exchange rates. All remeasurement gains and losses are included in determining net loss. Transaction gains and losses were not significant during the years ended December 28, 2019 or December 29, 2018.
Net Loss Per Share | Net Loss Per Share The Company computes net loss per share using the two-class method required for participating securities. The Company considers restricted stock to be participating securities because holders of such shares have nonforfeitable dividend rights in the event of the Company’s declaration of a dividend for common shares. Under the two-class method, undistributed earnings are allocated to common stock and the participating securities according to their respective participating rights in undistributed earnings, as if all the earnings for the period had been distributed. No allocation of undistributed earnings to participating securities was performed for periods with net losses as such securities do not have a contractual obligation to share in the losses of the Company. Basic net loss per share is calculated by dividing net loss by the weighted-average common shares outstanding during the period following the two-class method. Diluted net loss per share is calculated by dividing the net loss by the weighted-average shares and dilutive potential common shares outstanding during the period. Dilutive potential shares consist of dilutive shares issuable upon the exercise of outstanding stock options and warrants computed using the treasury stock method, shares issuable under the conversion feature of convertible notes using the “if-converted” method, and shares issuable upon the vesting of restricted stock. In periods of losses, basic and diluted loss per share are the same, as the effect of stock options, warrants, convertible notes and unvested restricted stock awards on loss per share is anti-dilutive.
Adoption of New Accounting Pronouncements | Adoption of New Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842), as amended ("ASC 842"), which modifies lease accounting for lessees to increase transparency and comparability by recording lease assets and liabilities for operating leases and disclosing key information about leasing arrangements. The Company adopted ASC 842 effective December 30, 2018 using a modified retrospective method and did not restate comparative periods. As permitted under the transition guidance, the Company carried forward the assessment of whether its contracts contain or are leases, classification of its leases and remaining lease terms. The Company also used hindsight in determining lease terms. Based on the lease portfolio as of December 30, 2018, the Company recognized approximately $1.5 million of operating lease right-of-use assets and operating lease liabilities on its consolidated balance sheet upon adoption, primarily relating to real estate. No adjustments were required to be made to accumulated deficit upon adoption.
Recent Accounting Pronouncements | Recent Accounting Pronouncements In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also clarifies and simplifies other aspects of the accounting for income taxes. ASU 2019-12 is effective for the Company beginning January 3, 2021 with early adoption permitted for any interim period before the effective date. Certain amendments of ASU 2019-12 may be adopted on a retrospective basis, modified retrospective basis or prospective basis. The Company is currently evaluating the impact ASU 2019-12 will have on its consolidated financial statements. In August 2018, the FASB issued ASU No. 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 (a consensus of the FASB Emerging Issues Task Force)(“ASU 2018-15”), which amends the accounting for implementation, setup, and other upfront costs in a hosting arrangement that is a service contract. ASU 2018-15 is effective for the Company beginning December 29, 2019 with early adoption permitted for any interim period before the effective date. The Company does not expect the adoption of ASU 2018-15 will have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which removes, modifies, and adds various disclosure requirements on fair value measurements in Topic 820. ASU 2018-13 is effective for the Company beginning December 29, 2019 with early adoption permitted upon the issuance of this ASU. The amendments of ASU 2018-13 on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. The Company does not expect the adoption of ASU 2018-13 will have a material impact on its consolidated financial statements.
