Accounting Policies [Abstract] |
The Company and Summary of Significant Accounting Policies | Note 1: The Company and Summary of Significant Accounting Policies The Company MoSys, Inc. (the “Company”) was incorporated in California in September 1991 and reincorporated in September 2000 in Delaware. The Company’s strategy and primary business objective is to be an IP-rich fabless semiconductor company focused on the development and sale of integrated circuit (“IC”) products. Its Bandwidth Engine ICs combine the Company’s proprietary high-density embedded memory with its high-speed 10 gigabits per second and higher interface technology. The Company’s future success and ability to achieve and maintain profitability depends on its success in developing a market for its ICs. Basis of Presentation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. The Company’s fiscal year ends on December 31 of each calendar year. Reverse Stock Split In February 2017, the Company effected a one-for-10 reverse stock split of its common stock. As a result of the reverse stock split, every ten shares of the Company’s pre-reverse split outstanding common stock were combined and reclassified into one share of common stock. Proportionate voting rights and other rights of common stock holders were not affected by the reverse stock split. No fractional shares were issued in connection with the reverse stock split; stockholders who would otherwise hold a fractional share of common stock received cash in an amount equal to the product obtained by multiplying (i) the closing sale price of the Company’s common stock on the effective date of the reverse stock split, by (ii) the number of shares of the Company’s common stock held by the stockholder that would otherwise have been exchanged for the fractional share interest. All stock options and restricted stock units outstanding and common stock reserved for issuance under the Company’s equity incentive plans immediately prior to the reverse stock split were adjusted by dividing the number of affected shares of common stock by 10 and, as applicable, multiplying the exercise price by 10, as a result of the reverse stock split. The common stock par value was adjusted to $0.001 in conjunction with the reverse stock split. All of the 2016 share numbers, share prices, and exercise prices have been adjusted, on a retroactive basis to reflect this 1-for-10 reverse stock split. Use of Estimates The preparation of financial statements in accordance with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses recognized during the reported period. Actual results could differ from those estimates. Cash Equivalents and Investments The Company has invested its excess cash in money market accounts, certificates of deposit, corporate debt, government-sponsored enterprise bonds and municipal bonds and considers all highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents. Investments with original maturities greater than three months and remaining maturities less than one year are classified as short-term investments. Investments with remaining maturities greater than one year are classified as long-term investments. Management generally determines the appropriate classification of securities at the time of purchase. All securities are classified as available-for-sale. The Company’s available-for-sale short-term and long-term investments are carried at fair value, with the unrealized holding gains and losses reported in accumulated other comprehensive loss. Realized gains and losses and declines in the value judged to be other-than-temporary are included in the other income, net line item in the consolidated statements of operations and comprehensive loss. The cost of securities sold is based on the specific identification method. Fair Value Measurements The Company measures the fair value of financial instruments using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels: Level 1—Inputs used to measure fair value are unadjusted quoted prices that are available in active markets for the identical assets or liabilities as of the reporting date. Level 2—Pricing is provided by third party sources of market information obtained through the Company’s investment advisors, rather than models. The Company does not adjust for, or apply, any additional assumptions or estimates to the pricing information it receives from advisors. The Company’s Level 2 securities include cash equivalents and available-for-sale securities, which consisted primarily of certificates of deposit, corporate debt, and government agency and municipal debt securities from issuers with high-quality credit ratings. The Company’s investment advisors obtain pricing data from independent sources, such as Standard & Poor’s, Bloomberg and Interactive Data Corporation, and rely on comparable pricing of other securities because the Level 2 securities are not actively traded and have fewer observable transactions. The Company considers this the most reliable information available for the valuation of the securities. Level 3—Unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment are used to measure fair value. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. The determination of fair value for Level 3 investments and other financial instruments involves the most management judgment and subjectivity. Allowance for Doubtful Accounts The Company establishes an allowance for doubtful accounts to ensure that its trade receivables balances are not overstated due to uncollectibility. The Company performs ongoing customer credit evaluations within the context of the industry in which it operates and generally does not require collateral from its customers. A specific allowance of up to 100% of the invoice value is provided for any problematic customer balances. Delinquent account balances are written off after management has determined that the likelihood of collection is remote. The Company grants credit only to customers deemed creditworthy in the judgment of management. There was no allowance for doubtful accounts receivable as of December 31, 2018 and 2017. Inventory The Company values its inventories at the lower of cost, which approximates actual cost on a first-in, first-out basis, or net realizable value. The Company records inventory reserves for estimated obsolescence or unmarketable inventories based upon assumptions about future demand and market conditions. Once a reserve is established, it is maintained until the product to which it relates is sold or otherwise disposed of. If actual market conditions are less favorable than those expected by management, additional adjustment to inventory valuation may be required. Charges for obsolete and slow-moving inventories are recorded based upon an analysis of specific identification of obsolete inventory items and quantification of slow-moving inventory items. The Company recorded inventory write-downs during the years ended December 31, 2018 and 2017 of $0.1 million and $0.3 million, respectively, and no inventory write-downs during the year ended December 31, 2016. Property and Equipment Property and equipment are originally recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally three to five years. Depreciation is recorded in cost of sales and operating expenses in the consolidated statements of operations and comprehensive loss. Leasehold improvements and assets acquired through capital leases are amortized over the shorter of their estimated useful life or the lease term, and amortization is recorded in operating expenses in the consolidated statements of operations and comprehensive loss. Valuation of Long-lived Assets The Company evaluates the recoverability of long-lived assets with finite lives whenever events or changes in circumstances occur that indicate that the carrying value of the asset or asset group may not be recoverable. Finite-lived intangible assets are being amortized on a straight-line basis over their estimated useful lives of three to seven years. An impairment charge is recognized as the difference between the net book value of such assets and the fair value of such assets at the date of measurement. The measurement of impairment requires management to estimate future cash flows and the fair value of long-lived assets. Intangible Assets Intangible assets acquired in business combinations, referred to as purchased intangible assets, are accounted for based on the fair value of assets purchased and are amortized over the period in which economic benefit is estimated to be received. Goodwill The Company determines the amount of a potential goodwill impairment by comparing the fair value of the reporting unit with its carrying amount. To the extent the carrying value of a reporting unit exceeds its fair value, a goodwill impairment charge is recognized. The Company has determined that it has a single reporting unit for purposes of performing its goodwill impairment test. As the Company uses the market approach to determine the step one fair value, the price of its common stock is an important component of the fair value calculation. If the Company’s stock price continues to experience significant price and volume fluctuations, this will impact the fair value of the reporting unit, which can lead to potential impairment in future periods. The Company reviews goodwill for impairment on an annual basis or whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. The Company first assesses qualitative factors to determine whether it is more-likely-than-not that the fair value of the reporting unit is less than the carrying amount as a basis for determining whether it is necessary to perform an impairment test. If the qualitative assessment warrants further analysis, the Company compares the fair value of the reporting unit to its carrying value. The fair value of the reporting unit is determined using the market approach. If the fair value of the reporting unit exceeds the carrying value of net assets of the reporting unit, goodwill is not impaired. If the carrying value of the reporting unit’s goodwill exceeds its fair value, then the Company must record an impairment charge equal to the difference. Impairments During the fourth quarter of 2016, the Company concluded a triggering event had occurred due to a sustained decrease in the price per share of its common stock and related reduced market capitalization. The Company performed the first step of the impairment test to identify potential goodwill impairment, and the test results indicated the goodwill carrying value was greater than its fair value. The Company then performed a step-two analysis to compare the carrying amount of goodwill to the implied fair value of the goodwill, and the Company determined the estimated fair values of the assets and liabilities of its single reporting unit. The fair values of the assets and liabilities identified in the impairment test were determined using the combination of the income approach and the market approach. The implied fair value of goodwill was measured as the excess of the fair value of the Company’s single reporting unit over the fair value of its assets and liabilities. As a result of the step-two test, the Company recorded a non-cash impairment charge of $9.9 million during the fourth quarter of 2016. The Company performed its annual test for goodwill impairment as of September 1, 2018, and, the test results indicated the goodwill carrying value was greater than its implied fair value. Further, the Company concluded a triggering event had occurred due to the sustained decrease in the price per share of its common stock and related reduced market capitalization as of September 30, 2018 and performed an additional test for impairment resulting in further indication that the goodwill carrying value was still greater than its implied fair value. As a result of both of these tests, the Company recorded non-cash impairment charges totaling $3.2 million during the third quarter of 2018. As of December 31, 2018, the Company concluded a triggering event had occurred due to the sustained decrease in the price per share of its common stock and related reduced market capitalization and performed an additional test for impairment resulting in further indication that the goodwill carrying value was still greater than its implied fair value. As a result, the Company recorded a non-cash impairment charge of $9.7 million during the fourth quarter of 2018. Revenue Recognition On January 1, 2018, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (“ASC 606”) using the modified retrospective (cumulative effect) transition method. Under this transition method, results for reporting periods beginning January 1, 2018 or later are presented under ASC 606, while prior period results continue to be reported in accordance with previous guidance. The cumulative effect of the initial application of ASC 606 was recognized as an adjustment to accumulated deficit as of January 1, 2018 of $230,000. Overall, the adoption of ASC 606 did not have a material impact on the Company’s consolidated balance sheet, statement of operations and comprehensive loss and statement of cash flows for the year ended December 31, 2018. ASC 606 also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. As described below, the analysis of contracts under ASC 606 supports the recognition of revenue at a point in time, resulting in revenue recognition timing that is materially consistent with the Company’s historical practice of recognizing product revenue when title and risk of loss pass to the customer. Revenue is recognized when control over a product or service is transferred to a customer. Revenue is measured at the transaction price which is based on the amount of consideration that the Company expects to receive in exchange for transferring the promised goods or services to the customer and excludes any amounts collected on behalf of third parties. The Company enters into contracts that may include both products and services, which are generally capable of being distinct and accounted for as separate performance obligations. The Company does not have significant financing components, as payments from customers are typically due within 60 days of invoicing, and the Company has elected the practical expedient to net value financing components that are less than one year. Shipping and handling costs are generally incurred by the customer, and, therefore, are not recorded as revenue. The following table summarizes the cumulative effect of the changes to the Company’s unaudited consolidated balance sheet as of January 1, 2018 due to the adoption of ASC 606 (in thousands):

Additionally, as a result of the adoption of ASC 606, the Company changed its accounting policy for revenue recognition. Accounting Policy – Revenue Recognition The Company generates revenue primarily from sales of IC products and licensing of its intellectual property. Revenues are recognized when control is transferred to customers in amounts that reflect the consideration the Company expects to be entitled to receive in exchange for those goods. Revenue recognition is evaluated through the following five steps: (i) identification of the contract, or contracts, with a customer; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when or as a performance obligation is satisfied. IC products Revenue is recognized when performance obligations under the terms of a contract with a customer are satisfied. The majority of the Company's contracts have a single performance obligation to transfer products. Accordingly, the Company recognizes revenue when title and risk of loss have been transferred to the customer, generally at the time of shipment of products. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products and is generally based upon a negotiated, formula, list or fixed price. The Company sells its products both directly to customers and through distributors generally under agreements with payment terms typically 60 days or less. The Company may record an estimated allowance, at the time of shipment, for future returns and other charges against revenue consistent with the terms of sale. Royalty and other The Company’s licensing contracts typically provide for royalties based on the licensee’s use of the Company’s memory technology in its currently shipping commercial products. With the adoption of ASC 606 in January 2018, the Company estimates its royalty revenue in the calendar quarter in which the licensee uses the licensed technology. Payments are received in the subsequent quarter. Contract liabilities – deferred revenue The Company’s contract liabilities consist of advance customer payments and deferred revenue. The Company classifies advance customer payments and deferred revenue as current or non-current based on the timing of when the Company expects to recognize revenue. As of December 31, 2018, contract liabilities were in a current position and included in deferred revenue. During the twelve months ended December 31, 2018, the Company recognized revenue of $3.9 million that had been included in deferred revenue at December 31, 2017. See Note 8 for disaggregation of revenue by geography. Cost of Net Revenue Cost of net revenue consists primarily of direct and indirect costs of IC product sales and engineering personnel costs directly related to maintenance and support services specified in licensing agreements. Maintenance and support typically include engineering support to assist in the commencement of production of a licensee’s products. Advertising Costs Advertising costs are expensed as incurred. Advertising costs were not significant in the years ended December 31, 2018, 2017 and 2016. Research and Development Engineering costs are recorded as research and development expense in the period incurred. Stock-Based Compensation The Company recognizes stock-based compensation for awards on a straight-line basis over the requisite service period, usually the vesting period, based on the grant-date fair value. The Company records stock-based compensation expense for stock options granted to non-employees, excluding non-employee directors, based upon the estimated then-current fair value of the equity instrument using the Black-Scholes pricing model. Assumptions used to value the equity instruments are consistent with equity instruments issued to employees. The Company charges the value of the equity instrument to earnings over the term of the service agreement and the unvested shares underlying the option are subject to periodic revaluation over the remaining vesting period. Per Share Amounts Basic net loss per share is computed by dividing net loss for the period by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share gives effect to all potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of incremental shares of common stock issuable upon the exercise of stock options, vesting of stock awards and purchases under the employee stock purchase plan, conversion of convertible debt and exercise of warrants. The following table sets forth securities outstanding which were excluded from the computation of diluted net loss per share as their inclusion would be anti-dilutive (in thousands):

Total |  |  | 45,164 |  |  |  | 2,427 |  |  |  | 1,640 |
Income Taxes The Company determines deferred tax assets and liabilities based upon the differences between the financial statement and tax bases of the Company’s assets and liabilities using tax rates in effect for the year in which the Company expects the differences to affect taxable income. A valuation allowance is established for any deferred tax assets for which it is more likely than not that all or a portion of the deferred tax assets will not be realized. The Company files U.S. federal and state and foreign income tax returns in jurisdictions with varying statutes of limitations. The 2014 through 2018 tax years generally remain subject to examination by U.S. federal and state tax authorities, and the 2010 through 2018 tax years generally remain subject to examination by foreign tax authorities. As of December 31, 2018, the Company did not have any material unrecognized tax benefits nor expect its unrecognized tax benefits to change significantly over the next 12 months. The Company recognizes interest related to unrecognized tax benefits as income tax expense and penalties related to unrecognized tax benefits as other income and expense. During the years ended December 31, 2018, 2017 and 2016, the Company did not recognize any interest or penalties related to unrecognized tax benefits. Comprehensive Loss Comprehensive loss includes unrealized gains and losses on available-for-sale securities. Realized gains and losses on available-for-sale securities are reclassified from accumulated other comprehensive loss and included in other income, net in the consolidated statements of operations and comprehensive loss. All amounts recorded were not significant in the years ended December 31, 2018, 2017 and 2016. Recent Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02 (“ASU 2016-02”), Leases, which was further amended by ASU Nos. 2017-13, 2018-01, 2018-10 and 2018-11. The new guidance requires lessees to recognize a right-of-use asset and a lease liability equal to the present value of the lease payments for virtually all leases not classified as short term. Consistent with current U.S. GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily depend on its classification as a finance or operating lease. The ASU also will require disclosures to provide additional qualitative and quantitative information about the amounts recorded in the financial statements. ASU 2016-02 is effective for annual and interim reporting periods beginning after December 15, 2018, with early adoption permitted. The new standard requires a modified retrospective transition for application at the beginning of the earliest comparative period presented. The Company currently has identified one lease impacted by the adoption of this standard. A right of use asset and lease liability will be established for this operating lease. Because the remaining term of the lease at the time of adoption is only 22 months, the impact to both the statement of operations and the statement of cash flows for the initial measurement at present value and the amortization required in subsequent periods is not expected to differ materially from the Company’s current practice.
