Accounting Policies [Abstract] | |
Organization and Summary of Significant Accounting Policies | 1. Organization and Summary of Significant Accounting Policies Organization Ambarella, Inc. (the “Company”) was incorporated in the Cayman Islands on January 15, 2004. The Company is a leading developer of low-power semiconductor solutions offering high-definition (HD) and Ultra HD compression, image processing, and deep neural network processing. The Company combines its processor design capabilities with its expertise in video and image processing, algorithms and software to provide a technology platform that is designed to be easily scalable across multiple applications and enable rapid and efficient product development. The Company’s system-on-a-chip, or SoC, designs fully integrate high-definition video processing, image processing, artificial intelligence (AI) computer vision algorithms, audio processing and system functions onto a single chip, delivering exceptional video and image quality, differentiated functionality and low power consumption. The Company is currently addressing a broad range of human and computer vision applications, including professional and consumer security cameras, automotive cameras such as advanced driver assistance systems (ADAS), electronic mirrors, drive recorders, driver/cabin monitoring systems, autonomous driving, and industrial and robotic applications. The Company sells its solutions to leading original design manufacturers, or ODMs, and original equipment manufacturers, or OEMs, globally. Basis of Consolidation The Company’s fiscal year ends on January 31. The consolidated financial statements of the Company and its subsidiaries have been prepared in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”). All intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP 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 revenue and expense during the reported periods. Actual results could differ from those estimates. On an ongoing basis, management evaluates its estimates and assumptions, including those related to (i) write down of excess and obsolete inventories; (ii) the estimated useful lives of long-lived assets; (iii) the valuation of stock-based compensation awards and financial instruments; (iv) the probability of performance objectives achievement; (v) the realization of tax assets and estimates of tax liabilities, including reserves for uncertain tax positions. These estimates and assumptions are based on historical experience and on various other factors which the Company believes to be reasonable under the circumstances. The Company may engage third-party valuation specialists to assist with estimates related to the valuation of financial instruments, assets and stock awards associated with various contractual arrangements. Such estimates often require the selection of appropriate valuation methodologies and significant judgment. Actual results could differ from these estimates under different assumptions or circumstances and such differences could be material. Concentration of Risk The Company’s products are manufactured, assembled and tested by third-party contractors located primarily in Asia. The Company does not have long-term agreements with these contractors. A significant disruption in the operations of one or more of these contractors would impact the production of the Company’s products which could have a material adverse effect on its business, financial condition and results of operations. A substantial portion of the Company’s revenue is derived from sales through one of its distributors, WT Microelectronics Co., Ltd., formerly Wintech Microelectronics Co., Ltd., or Wintech, which serves as its non-exclusive sales representative in Asia other than Japan, and directly to one ODM customer, Chicony Electronics Co., Ltd., or Chicony. Termination of the relationships with these customers could result in a temporary or permanent loss of revenue. Furthermore, any credit issues from these customers could impair their abilities to make timely payment to the Company. See Note 15 for additional information regarding revenue and credit concentration with these customers. Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, marketable debt securities and accounts receivable. The Company maintains its cash primarily in checking accounts with reputable financial institutions. Cash deposits held with these financial institutions may exceed the amount of insurance provided on such deposits. The Company has not experienced any losses on deposits of its cash. In order to limit the exposure of each investment, the cash equivalents and marketable debt securities consist primarily of money market funds, asset-backed securities, commercial paper, U.S. government securities and debt securities of corporations which management assesses to be highly liquid. The Company does not hold or issue financial instruments for trading purposes. The Company performs ongoing credit evaluation of its customers and adjusts credit limits based upon payment history and customers’ credit worthiness. The Company regularly monitors collections and payments from its customers. Foreign Currency Transactions The U.S. dollar is the functional currency for the Company and its subsidiaries. Monetary assets and liabilities denominated in non-U.S. currencies are re-measured to U.S. dollars using current exchange rates in effect at the balance sheet date. Nonmonetary assets and liabilities are re-measured to U.S. dollars using historical exchange rates. Monetary and other accounts are re-measured to U.S. dollars using average exchange rates in effect during each period. Gains or losses from foreign currency re-measurement are included in other income, net in the consolidated statements of operations, and, to date, have not been material. Fair Value of Financial Instruments Fair value accounting is applied to all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed in the financial statements on a recurring basis. The carrying amounts reflected in the consolidated balance sheets for cash equivalents, accounts receivable, accounts payable, accrued liabilities and other current liabilities, approximate fair value due to the short-term nature. Cash Equivalents and Marketable Debt Securities The Company considers all highly liquid debt security investments with original maturities of less than three months at the time of purchase to be cash equivalents. Debt security investments that are highly liquid with original maturities at the time of purchase greater than three months are considered marketable debt securities. The Company classifies the marketable securities as “available-for-sale” securities and record them at fair value based on quoted market prices of similar assets. On February 1, 2020, the Company adopted ASU No. 2016-13 (ASU 2016-13), Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, using the modified retrospective transition method. Under this new guidance, the Company recognizes credit losses based on a forward-looking current expected credit losses (CECL) model instead of the previous incurred loss model for financial instruments. The Company estimates the expected losses whenever a security’s fair value is below its amortized cost basis. The expected loss is computed at an individual security level using the discounted cash flow method with the effective interest rate on the purchase date. In the determination of credit-related losses, the Company excludes securities with zero loss expectations such as assets backed by government agencies. There are various factors considered in its assessment of credit-related losses, including the extent to which the fair value is less than the amortized cost basis, adverse conditions related to an industry or an underlying loan obligator, the payment structure of the security, changes to the rating of the security and other factors that may affect the security credit. The credit-related portion of the loss is recognized in other income (loss), net in the consolidated income statement but is limited to the difference between the fair value and the amortized cost basis of the security, adjusted for accrued interest. The non-credit-related portion of the loss is recognized in the accumulated other comprehensive income (loss) in the consolidated balance sheet. The cumulative effect adjustment upon the adoption on February 1, 2020 was immaterial and the credit-related losses from the Company’s financial instruments were not material as of January 31, 2021. The Company measures the fair value of money market funds using quoted prices in active markets for identical assets and classifies them within Level 1. The fair value of the Company’s investments in other debt securities are obtained based on quoted prices for similar asserts in active markets, or model driven valuations using significant inputs derived from or corroborated by observable market data and are classified within Level 2. So far, the Company has no debt securities under unobservable inputs and classified within Level 3. Restricted Cash Amounts included in restricted cash represent those required to be set aside to secure certain transactions in a foreign entity. As of January 31, 2021 and 2020, the restricted cash was immaterial, respectively. The following table presents cash, cash equivalents and restricted cash reported on the consolidated balance sheets, and the sums are presented on the consolidated statements of cash flows: As of January 31, 2021 2020 2019 (in thousands) Cash and cash equivalents $ 241,274 $ 231,403 $ 194,047 Restricted cash 10 9 11 Total as presented in the consolidated statements of cash flows $ 241,284 $ 231,412 $ 194,058 Trade Accounts Receivable and Allowance for Credit Losses The Company’s accounts receivables are recorded at invoiced amounts less allowance for any credit losses. According to ASU 2016-13, the Company recognizes credit losses based on a forward-looking current expected credit losses (CECL). The Company makes estimates of expected credit losses based upon its assessment of various factors, including historical collection experience, the age of accounts receivable balances, credit quality of its customers, current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that may affect its ability to collect from customers. The changes in allowance for credit losses are recognized in the consolidated statement of operations. The uncollectible accounts receivables are written off in the period in which a determination is made that all commercially reasonable means of recovering them have been exhausted. There were no material write-offs of accounts receivable for the fiscal years ended January 31, 2021, 2020 and 2019, respectively. There was no material current expected credit losses recorded as of January 31, 2021 and 2020, respectively. Inventories The Company records inventories at the lower of cost or net realizable value. The cost includes materials and other production costs and is computed using standard cost on a first-in, first-out basis. Inventory reserves are recorded for estimated obsolescence or unmarketable inventories based on forecast of future demand and market conditions. Any adjustments to reduce the cost of inventories to their net realizable value are recognized in earnings in the current period. Property and Equipment Property and equipment are stated at cost and depreciated using the straight-line method over the estimated useful life for computer equipment, computer software, machinery, equipment and furniture and fixtures. Leasehold improvements are amortized over the shorter of the lease term or their estimated useful lives. Repairs and maintenance are charged to expense as incurred. Noncancelable Internal-Use Software License The Company accounts for a noncancelable on premise internal-use software license as the acquisition of an intangible asset and the incurrence of a liability to the extent that all or a portion of the software licensing fees are not paid on or before the license acquisition date. The intangible asset and related liability are recorded at net present value and interest expense is recorded over the payment term. Leases Effective February 1, 2019, the Company adopted Accounting Standards Codification (“ASC”) Topic 842, Leases, using the alternative transition method with an adjustment to the opening balance in the period of adoption without adjustment of comparative period financial statements. Under this new guidance, the Company recognizes leases as operating lease right-of-use (“ROU”) assets and corresponding lease liabilities at the lease commencement date based on the present value of future lease payments, while recognizing lease expenses under straight-line method through the lease term. The Company also elected the other available practical expedients, and has elected not to recognize ROU assets and lease liabilities that arise from short-term (12 months or less) leases. The Company does not combine lease components with non-lease components, and as a result, the non-lease components are accounted for separately. In determining the present value of lease payments, the Company uses the implicit interest rate if readily determinable. When the implicit rate is not readily determinable, the Company uses its incremental borrowing rate based on the information available at the lease commencement date. The Company's leases mainly include its worldwide office facilities which are classified as operating leases. Certain leases include renewal options that are under the Company's discretion. The renewal options are included in the ROU assets and liability calculation if it is reasonably certain that the Company will exercise the option. The Company's short-term leases and finance leases are immaterial as of January 31, 2021 and January 31, 2020, respectively. Goodwill and In-Process Research and Development The Company does not amortize goodwill. Acquired in-process research and development, or IPR&D, is capitalized at fair value as an intangible asset and amortization commences upon completion of the underlying projects. . Impairment of Long-Lived Assets Including Goodwill and Other Acquired Intangible Assets The Company reviews property and equipment and intangible assets, excluding goodwill, for impairment at least annually in the fourth fiscal quarter or whenever events or changes in circumstances indicate that the carrying amount of an asset, or asset group, may not be recoverable. Determination of recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset, or asset group to estimated undiscounted future cash flows expected to be generated by the asset, or asset group. If the carrying amount of an asset or asset group exceeds its estimated undiscounted future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset or asset group exceeds the estimated fair value of the asset or asset group. Fair value is determined based on the estimated discounted future cash flows expected to be generated by the asset or asset group. Events or changes in circumstances that may indicate that an asset is impaired include significant decreases in the market value of an asset, significant underperformance relative to expected historical or projected future results of operations, a change in the extent or manner in which an asset is utilized, significant declines in the estimated fair value of the overall Company for a sustained period, shifts in technology, loss of key management or personnel, changes in the Company’s operating model or strategy and competitive forces. There has been no occurrence of events to date that would trigger an impairment analysis. As such, no impairment charge has been recognized as of January 31, 2021. The Company tests the goodwill for impairment at least annually in the fourth fiscal quarter, or sooner whenever events or changes in circumstances indicate that the asset may be impaired. The Company has a single reporting unit for goodwill impairment test purposes based on its business and reporting structure. The Company is permitted to first assess qualitative factors to determine whether the two step goodwill impairment test is necessary. Further testing is only required if the Company determines, based on the qualitative assessment, that it is more likely than not that a reporting unit’s fair value is less than its carrying amount. Otherwise, no further impairment testing is required. Qualitative factors include industry and market considerations, overall financial performance, and other relevant events and factors affecting the reporting unit . Equity Investment The Company accounts for its investment in a privately held company as an equity investment and reports the investment in other non-current assets in the consolidated balance sheets. The Company chooses to measure this equity investment that does not have readily determinable fair value at cost minus any recorded impairments, adjusted for observable price changes in transactions for an identical or similar investment of the same issuer. Upon determining that an impairment or observable price change exists, the Company records any adjustment to the fair value of the investment through net income. To date, there have been no identified events or changes in circumstances that may have a significant effect on the fair value of this investment and the Company has not recognized any impairment losses related to this investment nor have there been any observable price changes. Revenue Recognition Effective February 1, 2018, the Company adopted ASC 606, Revenue from Contracts with Customers. As a result, the Company recognizes revenue when control of its goods and services is transferred to its customers. 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. The sale of semiconductor products accounts for the substantial majority of the Company’s consolidated revenue. Sales agreements with customers are renewable periodically and contain terms and conditions with respect to payment, delivery, warranty, supply and other rights. The Company considers an accepted customer purchase order, governed by sales agreement, to be the contract with the customer. For each contract, the Company considers the promise to transfer tangible products to be the identified performance obligation. Product sales contracts may include volume-based tiered pricing or rebates that are fulfilled in cash or product. In determining the transaction price, the Company accounts for the right of returns, cash rebates, commissions and other pricing adjustments as variable consideration and estimates these amounts based on the expected amount to be provided to customers and reduces the revenue recognized. The Company estimates sales returns and rebates based on the Company’s historical patterns of return and pricing credits. As the Company’s standard payment terms are 30 days to 60 days, the contracts have no financing component. Under ASC 606, the Company estimates the total consideration to be received by using the expected value method for each contract, computes weighted average selling price for each unit shipped in cases where there is a material right due to the presence of volume-based tiered pricing, allocates the total consideration between the identified performance obligations, and recognizes revenue when control of its goods and services is transferred to its customers. The Company considers product control to be transferred at a point in time 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 significant risk and rewards of ownership of the asset. The Company also enters into fixed-price engineering service agreements with certain customers. These agreements may include multiple performance obligations, such as software development services, licensing of intellectual property and post-contract customer support, or PCS. These multiple performance obligations are highly interdependent, highly interrelated, are typically not sold separately and do not have standalone selling prices. They are all inputs to generate one combined output which is incorporating the Company’s SoC into the customer’s product. Accordingly, the Company determines that they are not separately identifiable and shall be treated as a single performance obligation. Customers usually pay based on milestones achieved. Because payments received do not correspond directly with the value of the Company’s performance to date, for fixed-price engineering services arrangements, revenue is recognized using the time-based straight line method, which best depicts the Company’s performance toward complete satisfaction of the performance obligation based on the nature of such professional services. Revenues from engineering service agreements were not material for the fiscal years ended January 31, 2021, 2020 and 2019, respectively. Timing of revenue recognition may differ from the timing of invoicing to the Company’s customers. The Company records contract assets when revenue is recognized prior to invoicing. The Company’s contract assets are primarily related to satisfied but unbilled performance obligations associated with its engineering service agreements at the reporting date. As of January 31, 2021 and 2020, the contract assets for these unbilled receivables were not material. The Company’s contract liabilities consist of deferred revenue. The deferred revenue is primarily related to the portion of a transaction price that exceeds the weighted average selling price for products sold to date under tiered-pricing contracts which contain material rights. This deferred revenue is expected to be recognized over the course of the contract when products are delivered for future pricing below the weighted average selling price of the contract. For the twelve months ended January 31, 2021 and 2020, the Company did not recognize any material revenue adjustment, respectively, related to performance obligations satisfied in prior periods released from this deferred revenue. As of January 31, 2021 and 2020, the respective deferred revenues were not material. Additionally, the transaction price allocated to unsatisfied, or partially unsatisfied, purchase orders for contracts that are greater than a year was not material as of January 31, 2021 and 2020, respectively. The Company also elects not to disclose the value of unsatisfied or partially unsatisfied performance obligations due to original expected contract duration of one year or less and elects to exclude amounts collected from customers for all sales taxes from the transaction price. Cost of Revenue Cost of revenue includes cost of materials, cost associated with packaging and assembly, testing and shipping, cost of personnel, stock-based compensation, logistics and quality assurance, warranty cost, royalty expense, write-downs of inventories and allocation of overhead. Research and Development Research and development costs are expensed as incurred and consist primarily of personnel costs, product development costs, which include engineering services, development software and hardware tools, license fees, costs of fabrication of masks for prototype products, other development materials costs, depreciation of equipment and tools and allocation of facility costs, net of any research and development grants. As of January 31, 2021, there was approximately $1.4 million of grants recorded in prepaid expenses and other current assets and approximately $2.0 million of grants recorded in other non-current assets in the consolidated balance sheets. Selling, General and Administrative Selling, general and administrative expenses consist of personnel costs, travel and trade show costs, legal expenses, other professional services and occupancy costs. Advertising expenses were not material for the fiscal years ended January 31, 2021, 2020 and 2019, respectively. Stock-Based Compensation The Company measures stock-based compensation for equity awards granted to employees and directors based on the estimated fair value on the grant date, and recognizes that compensation as expense using the straight-line attribution method for service condition awards or using the graded-vesting attribution method for awards with performance conditions over the requisite service period, which is typically the vesting period of each award. The Company determines the fair value of restricted stock and restricted stock units with service or performance conditions based on the fair market value of its ordinary shares on the grant date. The Company uses the Black-Scholes option pricing model to determine the fair value of stock options. Determining the fair value of stock options on the grant date requires the input of various assumptions, including stock price of the underlying ordinary share, the exercise price of the stock option, expected volatility, expected term, risk-free interest rate and dividend rate. The Company calculates expected volatility based on its own historical stock price for a period commensurate with the expected term, which is computed based on its own historical exercise behavior. The risk-free interest rate is derived from an average of the U.S. Treasury constant maturity rates for the respective periods most closely commensurate with the expected term. The expected dividend yield is zero because the Company has not historically paid dividends and has no present intention to pay dividends. The Company uses the Lattice pricing model and Monte Carlo Simulation to evaluate the fair value of awards with market conditions, including assumptions of historical volatility and risk-free interest rate commensurate with the vesting term. The Company elects to account for forfeitures as they occur. Income Taxes The Company records income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in its financial statements or tax returns. In estimating future tax consequences, generally all expected future events other than enactments or changes in the tax law or rates are considered. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount expected to be realized. The Company applies authoritative guidance for the accounting for uncertainty in income taxes. The guidance requires that tax effects of a position be recognized only if it is “more likely than not” to be sustained based solely on its technical merits as of the reporting date. Upon estimating its tax positions and tax benefits, the Company considers and evaluates numerous factors, which may require periodic adjustments and which may not reflect the final tax liabilities. The Company adjusts its financial statements to reflect only those tax positions that are more likely than not to be sustained under examination. As part of the process of preparing consolidated financial statements, the Company is required to estimate its taxes in each of the jurisdictions in which it operates. The Company estimates actual current tax exposure together with assessing temporary differences resulting from differing treatment of items, such as accruals and allowances not currently deductible for tax purposes. These differences result in deferred tax assets, which are included in the consolidated balance sheets. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in the consolidated statements of operations become deductible expenses under applicable income tax laws, or loss or credit carryforwards are utilized. In assessing whether deferred tax assets may be realized, the Company considers whether it is more likely than not that some portion or all of deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. The Company makes estimates and judgments about its future taxable income based on assumptions that are consistent with its plans and estimates. Should the actual amounts differ from estimates, the amount of valuation allowance could be materially impacted. Any adjustment to the deferred tax asset valuation allowance would be recorded in the consolidated income statement for the periods in which the adjustment is determined to be required. Net Income (Loss) Per Ordinary Share Basic earnings (losses) per share is computed by dividing net income (loss) available to ordinary shareholders by the weighted-average number of ordinary shares outstanding during the period. Diluted earnings (losses) per share is computed by dividing net income (loss) available to ordinary shareholders by the weighted-average number of ordinary shares outstanding during the period increased to include the number of additional ordinary shares that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, shares to be purchased under the Company’s employee stock purchase plan, unvested restricted stock and restricted stock units. The dilutive effect of potentially dilutive securities is reflected in diluted earnings (losses) per share by application of the treasury stock method. Comprehensive Income (Loss) Comprehensive income (loss) includes unrealized gains or losses from available-for-sale securities that are excluded from net income (loss). Recent Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740.

Financial Instruments and Fair Value | 2. Financial Instruments and Fair Value The Company invests a portion of its cash in debt securities that are denominated in United States dollars. The investment portfolio consists of money market funds, asset-backed securities, commercial paper, U.S. government securities and debt securities of corporations. All of the investments are classified as available-for-sale securities and reported at fair value in the consolidated balance sheets as follows: As of January 31, 2021 Amortized Unrealized Unrealized Losses Fair Value (in thousands) Money market funds $ 171 $ — $ — $ 171 Commercial paper 66,181 — — 66,181 Corporate bonds 102,108 980 (7 ) 103,081 Asset-backed securities 15,740 164 — 15,904 U.S. government securities 29,383 82 — 29,465 Total cash equivalents and marketable debt securities $ 213,583 $ 1,226 $ (7 ) $ 214,802 As of January 31, 2020 Amortized Cost Unrealized Gains Unrealized Losses Fair Value (in thousands) Money market funds $ 8,284 $ — $ — $ 8,284 Commercial paper 63,390 — — 63,390 Corporate bonds 95,053 653 — 95,706 Asset-backed securities 23,062 69 (2 ) 23,129 U.S. government securities 20,524 48 — 20,572 Total cash equivalents and marketable debt securities $ 210,313 $ 770 $ (2 ) $ 211,081 As of January 31, 2021, there were no debt securities with unrealized losses for more than twelve months.

Upon adoption of ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, the Company estimates the expected losses at an individual security level whenever a security’s fair value is below its amortized cost basis using the discounted cash flow method. The credit-related portion of the loss is recognized in other income, net in the condensed consolidated statements of operations but is limited to the difference between the fair value and the amortized cost basis of the security, adjusted for accrued interest. The non-credit-related portion of the loss is recognized in accumulated other comprehensive income in the condensed consolidated balance sheets. The credit-related losses of the Company’s financial instruments were not material for the fiscal year ended January 31, 2021. The net amounts of unrealized gains and unrealized losses that are not credit-related are recognized in other comprehensive income. The following fair value hierarchy is applied for disclosure of the inputs used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Level 2—Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments. Level 3—Unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value. The inputs require significant management judgment or estimation. The Company measures the fair value of money market funds using quoted prices in active markets for identical assets and classifies them within Level 1. The fair value of the Company’s investments in other debt securities are obtained based on quoted prices for similar assets in active markets and are classified within Level 2. The following tables present the fair value of the financial instruments measured on a recurring basis as of January 31, 2021 and 2020, respectively: As of January 31, 2021 Total Level 1 Level 2 Level 3 (in thousands) Money market funds $ 171 $ 171 Commercial paper 66,181 66,181 Corporate bonds 103,081 103,081 Asset-backed securities 15,904 15,904 U.S. government securities 29,465 29,465 Total cash equivalents and marketable debt securities $ 214,802 $ 171 $ 214,631 $ — As of January 31, 2020 Total Level 1 Level 2 Level 3 (in thousands) Money market funds $ 8,284 $ 8,284 $ — $ — Commercial paper 63,390 — 63,390 — Corporate bonds 95,706 — 95,706 — Asset-backed securities 23,129 — 23,129 — U.S. government securities 20,572 — 20,572 — Total cash equivalents and marketable debt securities $ 211,081 $ 8,284 $ 202,797 $ — |

Employee Benefits and Stock-based Compensation | 11. Employee Benefits and Stock-based Compensation 401(k) Plan The Company maintains a defined contribution 401(k) plan (the “401(k) Plan”) for all of its eligible U.S. employees. Under the 401(k) Plan, eligible employees may contribute up to the Internal Revenue Service annual contribution limitation. The Company is responsible for administrative costs of the Plan. The Company has not had any matching contributions to date. Stock Option Plans 2004 Stock Plan. The 2004 Stock Plan provides for the grant of incentive stock options (“ISOs”) within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), nonstatutory stock options (“NSOs”), stock purchase rights to acquire restricted stock and restricted stock units. Upon the completion of the IPO, no additional awards will be granted under the 2004 Plan and the 2004 Plan was terminated. However, all outstanding stock options and other awards previously granted under the 2004 Plan will remain subject to the terms of the 2004 Plan. 2012 Equity Incentive Plan. The 2012 Equity Incentive Plan, or EIP, permits the grant of ISOs, within the meaning of Section 422 of the Code, to employees of the Company and any of the Company’s subsidiary corporations, and the grant of NSOs, stock appreciation rights, restricted stock, restricted stock units, performance units, performance shares, deferred stock units and dividend equivalents to employees, directors and consultants of the Company and any of the Company’s subsidiary corporations’ employees and consultants. The exercise price of ISOs granted to a holder of more than 10% of the voting power of all classes of the Company’s shares shall be no less than 110% of fair market value on the grant date. The exercise price of ISOs granted to other employees and NSOs shall be no less than 100% of fair market value on the grant date. Options granted under the Plan have a term of up to 10 years Restricted stock and restricted stock units granted to new employees generally vest as to 1/4th of the shares on the first anniversary service date of the grant and 1/16th of the shares vest every 3 months thereafter, so as to be 100% vested on the fourth anniversary of the vesting commencement date. Vesting schedules for other service condition, market condition or performance condition awards vary and are subject to approval by the board of directors; provided that the performance condition associated awards shall not vest at all until the performance conditions are achieved and are subject to the award’s holders continuing to provide services to the Company through such vesting dates. The performance condition awards are automatically forfeited in their entirety, without any cost to or action by the Company, if there has been no achievement of the performance. The holders of restricted stock have voting power and other rights with respect to such shares, provided, however, that such shares are held in escrow and subject to forfeiture until the shares vested. In the first quarter of fiscal year 2021 and 2020, the Company added 1,521,252 and 1,453,659 ordinary shares, respectively, to the ordinary shares reserved for issuance, pursuant to an “evergreen” provision contained in the EIP. Pursuant to such provision, on February 1st of each fiscal year, the number of ordinary shares reserved for issuance under the EIP is automatically increased by a number equal to the lesser of (i) 3,500,000 ordinary shares, (ii) four and one half percent (4.5%) of the aggregate number of ordinary shares outstanding on January 31st of the preceding fiscal year, or (iii) a lesser number of shares that may be determined by the Company’s Board of Directors. Amended and Restated The Amended and Restated 2012 Employee Stock Purchase Plan, or ESPP, permits eligible participants to purchase ordinary shares at a discount through contributions up to 15% of their eligible compensation, subject to any IRS limitations. The ESPP provides each offering and purchasing period of six months in duration. The purchase price is 85% of the lower of the closing price of the Company’s ordinary shares on the first trading day of each offering period or on the purchase date. In the first quarter of fiscal year 2021 and 2020, the Company added 422,570 and 403,794 ordinary shares, respectively, to the ordinary shares reserved for issuance, pursuant to an “evergreen” provision contained in the ESPP. Pursuant to such provision, on February 1st of each fiscal year, the number of ordinary shares reserved for issuance under the ESPP is automatically increased by a number equal to the lesser of (i) 1,500,000 ordinary shares, (ii) one and one quarter percent (1.25%) of the aggregate number of ordinary shares outstanding on such date, or (iii) an amount determined by the Company’s Board of Directors or a duly authorized committee of the Board of Directors. Stock-based Compensation The following table presents the classification of stock-based compensation for the periods indicated: Year Ended January 31, 2021 2020 2019 (in thousands) Stock-based compensation: Cost of revenue $ 1,328 $ 1,184 $ 1,261 Research and development 42,903 41,842 37,432 Selling, general and administrative 25,903 23,845 22,119 Total stock-based compensation $ 70,134 $ 66,871 $ 60,812 For the twelve months ended January 31, 2021, approximately $4.4 million of stock-based compensation expense was accrued in accrued and other current liabilities in the consolidated balance sheets. As of January 31, 2021, total unrecognized compensation cost related to unvested stock options was $3.1 million and is expected to be recognized over a weighted-average period of 2.40 years. Total unrecognized compensation cost related to unvested restricted stock units was $123.9 million and is expected to be recognized over a weighted-average period of 2.35 years. The restricted stock awards were fully vested as of January 31, 2021. The following table sets forth the weighted-average assumptions used to estimate the fair value of the stock options and employee stock purchase plan awards for the periods indicated: Year Ended January 31, 2021 2020 2019 Stock Options: Volatility 52 % 52 % 54 % Risk-free interest rate 0.52 % 1.82 % 2.77 % Expected term (years) 5.78 6.01 5.41 Dividend yield 0 % 0 % 0 % Employee stock purchase plan awards: Volatility 59 % 47 % 45 % Risk-free interest rate 0.21 % 2.23 % 2.15 % Expected term (years) 0.5 0.5 0.5 Dividend yield 0 % 0 % 0 % Starting from fiscal year 2019, the Company calculates expected volatility for stock options based on its own historical stock price for a period commensurate with the expected term. In the prior fiscal year, the Company calculated expected volatility for stock options based on the weighted average of historical volatilities of its own stock price and the stock prices of similar companies that are publicly available for a period commensurate with the expected term. The Company calculates expected volatility for ESPP based on its own historical stock price for a period commensurate with the offering period.

Effective December 31, 2019, the Company has structured its activities to comply with the International Tax Co-Operation (Economic Substance) Law, 2018 in the Cayman Islands. As part of the new structure, the Company is the general partner of a Canadian limited partnership, the ultimate beneficial owner, and is allocated all of the earnings of the partnership. The primary jurisdiction where our foreign earnings are derived is the Cayman Islands, where the Company is domiciled. Under the current laws of the Cayman Islands, the Company is not subject to tax on its income. For purposes of the reconciliation between the provision (benefit) for income taxes at the statutory rate and the effective tax rate, a notional U.S. 21% Year Ended January 31, 2021 2020 2019 (in thousands) Provision at U.S. notional statutory rate $ (12,034 ) $ (8,742 ) $ (7,256 ) U.S. state taxes 212 3 2 Non-U.S. foreign tax differential 12,989 10,458 9,226 Stock-based compensation 4,943 4,172 4,715 U.S. R&D credit (3,928 ) (3,109 ) (2,770 ) Valuation allowance — — (7,990 ) Other 301 382 (32 ) Provision (benefit) for income taxes $ 2,483 $ 3,164 $ (4,105 ) On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was enacted into law in the United States. The tax legislation contains several provisions that impacted the Company, including the reduction of the corporate income tax rate from 35% to 21%, acceleration of business asset expensing, and a reduction in the amount of executive pay that may qualify as a tax deduction, among others. The income tax benefit recorded for the fiscal year ended January 31, 2019 includes the impact of the Tax Act. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), P.L. 116-136, was passed into law, amending portions of certain relevant US tax laws. The CARES Act includes a number of federal income tax law changes, including, but not limited to: 1) permitting net operating loss carrybacks to offset 100% of taxable income for taxable years beginning before 2021, 2) accelerating alternative minimum tax credit refunds, 3) temporarily increasing the allowable business interest deduction from 30% to 50% of adjusted taxable income, and 4) providing a technical correction for depreciation related to qualified improvement property. The CARES Act also provides for an Employee Retention Credit, a fully refundable payroll tax credit for certain eligible employers, and the ability for all eligible employers to defer payment of the employer share of payroll taxes owed on wages paid for the period ending December 31, 2020. The Company evaluated the impact of the CARES Act and does not expect it will have a material impact on the Company’s condensed consolidated financial statements. Temporary differences that gave rise to significant portions of the Company’s deferred tax assets and liabilities at January 31, 2021 and 2020 were as follows: As of January 31, 2021 2020 (in thousands) Deferred tax assets: Federal and state credits $ 24,394 $ 21,275 Expenses not currently deductible 939 593 Operating lease liabilities 2,144 2,023 Stock-based compensation 3,349 3,203 Foreign deferred 184 132 Gross deferred tax assets 31,010 27,226 Valuation allowance (17,962 ) (14,670 ) Total deferred tax assets $ 13,048 $ 12,556 Deferred tax liabilities Property and equipment (1,443 ) (1,469 ) Operating lease assets (1,978 ) (1,974 ) Net deferred tax assets $ 9,627 $ 9,113 Tax valuation allowance for the periods indicated below were as follows: Deductions Additions Charged to Balance at Additional Charged to Expenses Balance at Beginning of Charged to Other or Other End of Period Expenses Account Accounts Period (in thousands) Tax Valuation Allowance Year ended January 31, 2021 $ 14,670 3,292 — — $ 17,962 Year ended January 31, 2020 $ 12,526 2,144 — — $ 14,670 Year ended January 31, 2019 $ 18,538 1,978 — (7,990 ) $ 12,526 The Company conducts its business in several countries and regions and is subject to taxation in those jurisdictions. The Company is incorporated in the Cayman Islands with foreign subsidiaries in the U.S., China, Taiwan, Italy and other foreign countries and regions. As such, the Company’s worldwide operating income is subject to varying tax rates and its effective tax rate is highly dependent upon the geographic distribution of its earnings or losses and the tax laws and regulations in each geographical region. Consequently, the Company has experienced lower effective tax rates as a substantial amount of its operations are conducted in lower-tax jurisdictions. If the Company’s operational structure was to change in such a manner that would increase the amount of operating income subject to taxation in higher-tax jurisdictions, or if the Company was to commence operations in jurisdictions assessing relatively higher tax rates, its effective tax rate could fluctuate significantly on a quarterly basis and/or be adversely affected. Dividend distributions received from the Company’s U.S. subsidiary and certain other foreign subsidiaries may be subject to local country withholding taxes when, and if, distributed. Deferred tax liabilities have not been recorded on unremitted earnings of certain subsidiaries because management’s intent is to indefinitely reinvest any undistributed earnings in those subsidiaries. If dividend distributions from those subsidiaries were to occur, the liability as of January 31, 2021 would be $12.4 million. Cumulative undistributed earnings of foreign subsidiaries for which no deferred taxes have been provided approximated $85.1 million at January 31, 2021. As of January 31, 2021 and 2020, the Company had deferred tax assets (net of deferred tax liabilities) before valuation allowance, of $27.6 million and $23.8 million, respectively. The Company assesses whether a valuation allowance should be established against its deferred tax assets based on the consideration of all available evidence, using a “more likely than not” standard. The Company has $2.7 million of California net operating loss carryforwards as of January 31, 2021. The California net operating loss carryforwards begin to expire in fiscal year 2036, if not utilized. For financial statement purposes these carry forwards are offset by uncertain tax positions. The Company also has Federal and California state research and development credit carryforwards of approximately $22.4 million and $27.1 million, respectively, at January 31, 2021. The Federal credits begin to expire in fiscal year 2035. The California credits can be carried forward indefinitely. The Company reports its U.S. state deferred tax assets and related valuation allowance, net of the U.S federal tax rate of 21%. As of January 31, 2021, the Company has recorded a valuation allowance of $18.0 million against all of its U.S. state deferred tax assets due to uncertainty regarding the future utilization of these deferred tax assets. Utilization of the research credit carryforwards may be subject to an annual limitation due to the ownership percentage change limitations as defined by the U.S. Internal Revenue Code Section 382, as amended, and similar state provisions. The annual limitation may result in the expiration of the U.S. Federal and state research credit carryforwards before utilization. The Company does not expect any tax credit carryforwards to expire as a result of a Section 382 limitation. The Company applies the provisions of FASB’s guidance on accounting for uncertainty in income taxes. As of January 31, 2021, the Company had approximately $27.3 million in unrecognized tax benefits, $21.4 million of which would affect the Company’s effective tax rate if recognized. The remainder of the unrecognized tax benefits would not affect the effective tax rate due to the full valuation recorded for state deferred tax assets. Year Ended January 31, 2021 2020 2019 (in thousands) Beginning balance: $ 42,695 $ 37,531 $ 34,117 Additions based on tax positions related to the current year 3,360 4,964 3,922 Additions for tax positions of prior years 16 252 109 Reductions for tax positions in prior years (12,483 ) — (552 ) Settlements for prior periods (6,087 ) — — Lapse of applicable statute of limitations (245 ) (52 ) (65 ) Ending balance: $ 27,256 $ 42,695 $ 37,531 The Company classified $7.9 million and $7.5 million of income tax liabilities as other long-term liabilities as of January 31, 2021 and 2020, respectively, because payment of cash or settlement is not anticipated within one year from the balance sheet date. The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense. The Company recorded $283,000 and $358,000 and $263,000 of interest expense and penalties related to uncertain tax positions for the fiscal years ended January 31, 2021, 2020 and 2019, respectively. The Company recorded noncurrent liabilities of $1,043,000 and $760,000 related to interest and penalties for uncertain tax positions at January 31, 2021 and 2020, respectively. The primary jurisdiction where our foreign earnings are derived is the Cayman Islands, where the Company is domiciled. The Company files income tax returns in the U.S. federal jurisdiction as well as many U.S. state and foreign jurisdictions. The Internal Revenue Service is currently examining the Company’s U.S. federal income tax return for the fiscal year ended January 31, 2017. The tax years 2013 to 2020 remain open to examination by U.S. federal tax authorities. The tax years 2009 to 2020 remain open to examination by U.S. state tax authorities. The tax years 2015 to 2020 remain open to examination by foreign tax authorities. Fiscal years outside of the normal statute of limitations remain open to audit by tax authorities due to tax attributes generated in those earlier years, which have been carried forward and may be audited in subsequent years when utilized. The Company regularly assesses the likelihood of adverse outcomes resulting from potential tax examinations to determine the adequacy of its provision for income taxes. These assessments can require considerable estimates and judgments. During the fiscal year ended January 31, 2021, the gross amount of unrecognized tax benefits decreased by $15.4 million to $ million. The decrease was primarily due to changes to our uncertain tax positions from adjustments arising from tax return filings based on our ongoing exam with the Internal Revenue Service. If the estimates of income tax liabilities prove to be less than the ultimate assessment, then a further charge to expense could be required. If events occur, and the payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities could result in tax benefits being recognized in the period in which the Company determines the liabilities are no longer necessary. The Company does not anticipate significant changes to its uncertain tax positions during the next twelve months. As of January 31, 2021, the Company’s long-term income taxes payable, including estimated interest and penalties, was approximately $9.0 million. The Company was unable to make a reasonably reliable estimate of the timing of payments in individual years due to uncertainties in the timing of tax audits, if any, or their outcomes. On July 27, 2015, the United States Tax Court issued a decision (“Tax Court Decision”) in Altera Corp. v. Commissioner |

Commitments and Contingencies | 14. Commitments and Contingencies Contract Manufacturer Commitments The Company’s components and products are procured and built by independent contract manufacturers based on sales forecasts. These forecasts include estimates of future demand, historical trends, analysis of sales and marketing activities, and adjustment of overall market conditions. The Company regularly issues purchase orders to independent contract manufacturers which are cancelable only upon the agreement between the Company and the third-party. As of January 31, 2021 and 2020, total manufacturing purchase commitments were approximately $48.2 million and $35.9 million, respectively. Indemnification The Company, from time to time, in the normal course of business, indemnifies certain vendors with whom it enters into contractual relationships. The Company has agreed to hold the other party harmless against third-party claims in connection with the Company’s future products. The Company also indemnifies certain customers against third-party claims related to certain intellectual property matters. It is not possible to determine the maximum potential amount of liability under these indemnification obligations due to the limited history of prior indemnification claims and the unique facts and circumstances that are likely to be involved in each particular claim. The Company has not made payments under these obligations and no liabilities have been recorded for these obligations on the consolidated balance sheets as of January 31, 2021 and 2020, respectively. |

The Company sells its solutions to leading original design manufacturers, or ODMs, and original equipment manufacturers, or OEMs, globally. |
Basis of Consolidation | Basis of Consolidation The Company’s fiscal year ends on January 31. The consolidated financial statements of the Company and its subsidiaries have been prepared in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”). All intercompany transactions and balances have been eliminated in consolidation. |
Use of Estimates | Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP 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 revenue and expense during the reported periods. Actual results could differ from those estimates. On an ongoing basis, management evaluates its estimates and assumptions, including those related to (i) write down of excess and obsolete inventories; (ii) the estimated useful lives of long-lived assets; (iii) the valuation of stock-based compensation awards and financial instruments; (iv) the probability of performance objectives achievement; (v) the realization of tax assets and estimates of tax liabilities, including reserves for uncertain tax positions. These estimates and assumptions are based on historical experience and on various other factors which the Company believes to be reasonable under the circumstances. The Company may engage third-party valuation specialists to assist with estimates related to the valuation of financial instruments, assets and stock awards associated with various contractual arrangements. Such estimates often require the selection of appropriate valuation methodologies and significant judgment. Actual results could differ from these estimates under different assumptions or circumstances and such differences could be material. |
Concentration of Risk | Concentration of Risk The Company’s products are manufactured, assembled and tested by third-party contractors located primarily in Asia. The Company does not have long-term agreements with these contractors. A significant disruption in the operations of one or more of these contractors would impact the production of the Company’s products which could have a material adverse effect on its business, financial condition and results of operations. A substantial portion of the Company’s revenue is derived from sales through one of its distributors, WT Microelectronics Co., Ltd., formerly Wintech Microelectronics Co., Ltd., or Wintech, which serves as its non-exclusive sales representative in Asia other than Japan, and directly to one ODM customer, Chicony Electronics Co., Ltd., or Chicony. Termination of the relationships with these customers could result in a temporary or permanent loss of revenue. Furthermore, any credit issues from these customers could impair their abilities to make timely payment to the Company. See Note 15 for additional information regarding revenue and credit concentration with these customers. Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, marketable debt securities and accounts receivable. The Company maintains its cash primarily in checking accounts with reputable financial institutions. Cash deposits held with these financial institutions may exceed the amount of insurance provided on such deposits. The Company has not experienced any losses on deposits of its cash. In order to limit the exposure of each investment, the cash equivalents and marketable debt securities consist primarily of money market funds, asset-backed securities, commercial paper, U.S. government securities and debt securities of corporations which management assesses to be highly liquid. The Company does not hold or issue financial instruments for trading purposes. The Company performs ongoing credit evaluation of its customers and adjusts credit limits based upon payment history and customers’ credit worthiness. The Company regularly monitors collections and payments from its customers. |
Foreign Currency Transactions | Foreign Currency Transactions The U.S. dollar is the functional currency for the Company and its subsidiaries. Monetary assets and liabilities denominated in non-U.S. currencies are re-measured to U.S. dollars using current exchange rates in effect at the balance sheet date. Nonmonetary assets and liabilities are re-measured to U.S. dollars using historical exchange rates. Monetary and other accounts are re-measured to U.S. dollars using average exchange rates in effect during each period. Gains or losses from foreign currency re-measurement are included in other income, net in the consolidated statements of operations, and, to date, have not been material. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments Fair value accounting is applied to all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed in the financial statements on a recurring basis. The carrying amounts reflected in the consolidated balance sheets for cash equivalents, accounts receivable, accounts payable, accrued liabilities and other current liabilities, approximate fair value due to the short-term nature. |
Cash Equivalents and Marketable Debt Securities | Cash Equivalents and Marketable Debt Securities The Company considers all highly liquid debt security investments with original maturities of less than three months at the time of purchase to be cash equivalents. Debt security investments that are highly liquid with original maturities at the time of purchase greater than three months are considered marketable debt securities. The Company classifies the marketable securities as “available-for-sale” securities and record them at fair value based on quoted market prices of similar assets. On February 1, 2020, the Company adopted ASU No. 2016-13 (ASU 2016-13), Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, using the modified retrospective transition method. Under this new guidance, the Company recognizes credit losses based on a forward-looking current expected credit losses (CECL) model instead of the previous incurred loss model for financial instruments. The Company estimates the expected losses whenever a security’s fair value is below its amortized cost basis. The expected loss is computed at an individual security level using the discounted cash flow method with the effective interest rate on the purchase date. In the determination of credit-related losses, the Company excludes securities with zero loss expectations such as assets backed by government agencies. There are various factors considered in its assessment of credit-related losses, including the extent to which the fair value is less than the amortized cost basis, adverse conditions related to an industry or an underlying loan obligator, the payment structure of the security, changes to the rating of the security and other factors that may affect the security credit. The credit-related portion of the loss is recognized in other income (loss), net in the consolidated income statement but is limited to the difference between the fair value and the amortized cost basis of the security, adjusted for accrued interest. The non-credit-related portion of the loss is recognized in the accumulated other comprehensive income (loss) in the consolidated balance sheet. The cumulative effect adjustment upon the adoption on February 1, 2020 was immaterial and the credit-related losses from the Company’s financial instruments were not material as of January 31, 2021. The Company measures the fair value of money market funds using quoted prices in active markets for identical assets and classifies them within Level 1. The fair value of the Company’s investments in other debt securities are obtained based on quoted prices for similar asserts in active markets, or model driven valuations using significant inputs derived from or corroborated by observable market data and are classified within Level 2. So far, the Company has no debt securities under unobservable inputs and classified within Level 3. |
Restricted Cash | Restricted Cash Amounts included in restricted cash represent those required to be set aside to secure certain transactions in a foreign entity. As of January 31, 2021 and 2020, the restricted cash was immaterial, respectively. The following table presents cash, cash equivalents and restricted cash reported on the consolidated balance sheets, and the sums are presented on the consolidated statements of cash flows: As of January 31, 2021 2020 2019 (in thousands) Cash and cash equivalents $ 241,274 $ 231,403 $ 194,047 Restricted cash 10 9 11 Total as presented in the consolidated statements of cash flows $ 241,284 $ 231,412 $ 194,058 |
Trade Accounts Receivable and Allowance for Credit Losses | Trade Accounts Receivable and Allowance for Credit Losses The Company’s accounts receivables are recorded at invoiced amounts less allowance for any credit losses. According to ASU 2016-13, the Company recognizes credit losses based on a forward-looking current expected credit losses (CECL). The Company makes estimates of expected credit losses based upon its assessment of various factors, including historical collection experience, the age of accounts receivable balances, credit quality of its customers, current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that may affect its ability to collect from customers. The changes in allowance for credit losses are recognized in the consolidated statement of operations. The uncollectible accounts receivables are written off in the period in which a determination is made that all commercially reasonable means of recovering them have been exhausted. There were no material write-offs of accounts receivable for the fiscal years ended January 31, 2021, 2020 and 2019, respectively. There was no material current expected credit losses recorded as of January 31, 2021 and 2020, respectively. |
Inventories | Inventories The Company records inventories at the lower of cost or net realizable value. The cost includes materials and other production costs and is computed using standard cost on a first-in, first-out basis. Inventory reserves are recorded for estimated obsolescence or unmarketable inventories based on forecast of future demand and market conditions. Any adjustments to reduce the cost of inventories to their net realizable value are recognized in earnings in the current period. |
Property and Equipment | Property and Equipment Property and equipment are stated at cost and depreciated using the straight-line method over the estimated useful life for computer equipment, computer software, machinery, equipment and furniture and fixtures. Leasehold improvements are amortized over the shorter of the lease term or their estimated useful lives. Repairs and maintenance are charged to expense as incurred. |
Noncancelable Internal-Use Software License | Noncancelable Internal-Use Software License The Company accounts for a noncancelable on premise internal-use software license as the acquisition of an intangible asset and the incurrence of a liability to the extent that all or a portion of the software licensing fees are not paid on or before the license acquisition date. The intangible asset and related liability are recorded at net present value and interest expense is recorded over the payment term. |
Leases | Leases Effective February 1, 2019, the Company adopted Accounting Standards Codification (“ASC”) Topic 842, Leases, using the alternative transition method with an adjustment to the opening balance in the period of adoption without adjustment of comparative period financial statements. Under this new guidance, the Company recognizes leases as operating lease right-of-use (“ROU”) assets and corresponding lease liabilities at the lease commencement date based on the present value of future lease payments, while recognizing lease expenses under straight-line method through the lease term. The Company also elected the other available practical expedients, and has elected not to recognize ROU assets and lease liabilities that arise from short-term (12 months or less) leases. The Company does not combine lease components with non-lease components, and as a result, the non-lease components are accounted for separately. In determining the present value of lease payments, the Company uses the implicit interest rate if readily determinable. When the implicit rate is not readily determinable, the Company uses its incremental borrowing rate based on the information available at the lease commencement date. The Company's leases mainly include its worldwide office facilities which are classified as operating leases. Certain leases include renewal options that are under the Company's discretion. The renewal options are included in the ROU assets and liability calculation if it is reasonably certain that the Company will exercise the option. The Company's short-term leases and finance leases are immaterial as of January 31, 2021 and January 31, 2020, respectively. |
Goodwill and In-Process Research and Development | Goodwill and In-Process Research and Development The Company does not amortize goodwill. Acquired in-process research and development, or IPR&D, is capitalized at fair value as an intangible asset and amortization commences upon completion of the underlying projects. . |
Impairment of Long-Lived Assets Including Goodwill and Other Acquired Intangible Assets | Impairment of Long-Lived Assets Including Goodwill and Other Acquired Intangible Assets The Company reviews property and equipment and intangible assets, excluding goodwill, for impairment at least annually in the fourth fiscal quarter or whenever events or changes in circumstances indicate that the carrying amount of an asset, or asset group, may not be recoverable. Determination of recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset, or asset group to estimated undiscounted future cash flows expected to be generated by the asset, or asset group. If the carrying amount of an asset or asset group exceeds its estimated undiscounted future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset or asset group exceeds the estimated fair value of the asset or asset group. Fair value is determined based on the estimated discounted future cash flows expected to be generated by the asset or asset group. Events or changes in circumstances that may indicate that an asset is impaired include significant decreases in the market value of an asset, significant underperformance relative to expected historical or projected future results of operations, a change in the extent or manner in which an asset is utilized, significant declines in the estimated fair value of the overall Company for a sustained period, shifts in technology, loss of key management or personnel, changes in the Company’s operating model or strategy and competitive forces. There has been no occurrence of events to date that would trigger an impairment analysis. As such, no impairment charge has been recognized as of January 31, 2021. The Company tests the goodwill for impairment at least annually in the fourth fiscal quarter, or sooner whenever events or changes in circumstances indicate that the asset may be impaired. The Company has a single reporting unit for goodwill impairment test purposes based on its business and reporting structure. The Company is permitted to first assess qualitative factors to determine whether the two step goodwill impairment test is necessary. Further testing is only required if the Company determines, based on the qualitative assessment, that it is more likely than not that a reporting unit’s fair value is less than its carrying amount. Otherwise, no further impairment testing is required. Qualitative factors include industry and market considerations, overall financial performance, and other relevant events and factors affecting the reporting unit . |
Equity Investment | Equity Investment The Company accounts for its investment in a privately held company as an equity investment and reports the investment in other non-current assets in the consolidated balance sheets. The Company chooses to measure this equity investment that does not have readily determinable fair value at cost minus any recorded impairments, adjusted for observable price changes in transactions for an identical or similar investment of the same issuer. Upon determining that an impairment or observable price change exists, the Company records any adjustment to the fair value of the investment through net income. To date, there have been no identified events or changes in circumstances that may have a significant effect on the fair value of this investment and the Company has not recognized any impairment losses related to this investment nor have there been any observable price changes. |
Revenue Recognition | Revenue Recognition Effective February 1, 2018, the Company adopted ASC 606, Revenue from Contracts with Customers. As a result, the Company recognizes revenue when control of its goods and services is transferred to its customers. 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. The sale of semiconductor products accounts for the substantial majority of the Company’s consolidated revenue. Sales agreements with customers are renewable periodically and contain terms and conditions with respect to payment, delivery, warranty, supply and other rights. The Company considers an accepted customer purchase order, governed by sales agreement, to be the contract with the customer. For each contract, the Company considers the promise to transfer tangible products to be the identified performance obligation. Product sales contracts may include volume-based tiered pricing or rebates that are fulfilled in cash or product. In determining the transaction price, the Company accounts for the right of returns, cash rebates, commissions and other pricing adjustments as variable consideration and estimates these amounts based on the expected amount to be provided to customers and reduces the revenue recognized. The Company estimates sales returns and rebates based on the Company’s historical patterns of return and pricing credits. As the Company’s standard payment terms are 30 days to 60 days, the contracts have no financing component. Under ASC 606, the Company estimates the total consideration to be received by using the expected value method for each contract, computes weighted average selling price for each unit shipped in cases where there is a material right due to the presence of volume-based tiered pricing, allocates the total consideration between the identified performance obligations, and recognizes revenue when control of its goods and services is transferred to its customers. The Company considers product control to be transferred at a point in time 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 significant risk and rewards of ownership of the asset. The Company also enters into fixed-price engineering service agreements with certain customers. These agreements may include multiple performance obligations, such as software development services, licensing of intellectual property and post-contract customer support, or PCS. These multiple performance obligations are highly interdependent, highly interrelated, are typically not sold separately and do not have standalone selling prices. They are all inputs to generate one combined output which is incorporating the Company’s SoC into the customer’s product. Accordingly, the Company determines that they are not separately identifiable and shall be treated as a single performance obligation. Customers usually pay based on milestones achieved. Because payments received do not correspond directly with the value of the Company’s performance to date, for fixed-price engineering services arrangements, revenue is recognized using the time-based straight line method, which best depicts the Company’s performance toward complete satisfaction of the performance obligation based on the nature of such professional services. Revenues from engineering service agreements were not material for the fiscal years ended January 31, 2021, 2020 and 2019, respectively. Timing of revenue recognition may differ from the timing of invoicing to the Company’s customers. The Company records contract assets when revenue is recognized prior to invoicing. The Company’s contract assets are primarily related to satisfied but unbilled performance obligations associated with its engineering service agreements at the reporting date. As of January 31, 2021 and 2020, the contract assets for these unbilled receivables were not material. The Company’s contract liabilities consist of deferred revenue. The deferred revenue is primarily related to the portion of a transaction price that exceeds the weighted average selling price for products sold to date under tiered-pricing contracts which contain material rights. This deferred revenue is expected to be recognized over the course of the contract when products are delivered for future pricing below the weighted average selling price of the contract. For the twelve months ended January 31, 2021 and 2020, the Company did not recognize any material revenue adjustment, respectively, related to performance obligations satisfied in prior periods released from this deferred revenue. As of January 31, 2021 and 2020, the respective deferred revenues were not material. Additionally, the transaction price allocated to unsatisfied, or partially unsatisfied, purchase orders for contracts that are greater than a year was not material as of January 31, 2021 and 2020, respectively. The Company also elects not to disclose the value of unsatisfied or partially unsatisfied performance obligations due to original expected contract duration of one year or less and elects to exclude amounts collected from customers for all sales taxes from the transaction price. |
Cost of Revenue | Cost of Revenue Cost of revenue includes cost of materials, cost associated with packaging and assembly, testing and shipping, cost of personnel, stock-based compensation, logistics and quality assurance, warranty cost, royalty expense, write-downs of inventories and allocation of overhead. |
Research and Development | Research and Development Research and development costs are expensed as incurred and consist primarily of personnel costs, product development costs, which include engineering services, development software and hardware tools, license fees, costs of fabrication of masks for prototype products, other development materials costs, depreciation of equipment and tools and allocation of facility costs, net of any research and development grants. As of January 31, 2021, there was approximately $1.4 million of grants recorded in prepaid expenses and other current assets and approximately $2.0 million of grants recorded in other non-current assets in the consolidated balance sheets. |
Selling, General and Administrative | Selling, General and Administrative Selling, general and administrative expenses consist of personnel costs, travel and trade show costs, legal expenses, other professional services and occupancy costs. Advertising expenses were not material for the fiscal years ended January 31, 2021, 2020 and 2019, respectively. |
Stock-Based Compensation | Stock-Based Compensation The Company measures stock-based compensation for equity awards granted to employees and directors based on the estimated fair value on the grant date, and recognizes that compensation as expense using the straight-line attribution method for service condition awards or using the graded-vesting attribution method for awards with performance conditions over the requisite service period, which is typically the vesting period of each award. The Company determines the fair value of restricted stock and restricted stock units with service or performance conditions based on the fair market value of its ordinary shares on the grant date. The Company uses the Black-Scholes option pricing model to determine the fair value of stock options. Determining the fair value of stock options on the grant date requires the input of various assumptions, including stock price of the underlying ordinary share, the exercise price of the stock option, expected volatility, expected term, risk-free interest rate and dividend rate. The Company calculates expected volatility based on its own historical stock price for a period commensurate with the expected term, which is computed based on its own historical exercise behavior. The risk-free interest rate is derived from an average of the U.S. Treasury constant maturity rates for the respective periods most closely commensurate with the expected term. The expected dividend yield is zero because the Company has not historically paid dividends and has no present intention to pay dividends. The Company uses the Lattice pricing model and Monte Carlo Simulation to evaluate the fair value of awards with market conditions, including assumptions of historical volatility and risk-free interest rate commensurate with the vesting term. The Company elects to account for forfeitures as they occur. |
Income Taxes | Income Taxes The Company records income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in its financial statements or tax returns. In estimating future tax consequences, generally all expected future events other than enactments or changes in the tax law or rates are considered. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount expected to be realized. The Company applies authoritative guidance for the accounting for uncertainty in income taxes. The guidance requires that tax effects of a position be recognized only if it is “more likely than not” to be sustained based solely on its technical merits as of the reporting date. Upon estimating its tax positions and tax benefits, the Company considers and evaluates numerous factors, which may require periodic adjustments and which may not reflect the final tax liabilities. The Company adjusts its financial statements to reflect only those tax positions that are more likely than not to be sustained under examination. As part of the process of preparing consolidated financial statements, the Company is required to estimate its taxes in each of the jurisdictions in which it operates. The Company estimates actual current tax exposure together with assessing temporary differences resulting from differing treatment of items, such as accruals and allowances not currently deductible for tax purposes. These differences result in deferred tax assets, which are included in the consolidated balance sheets. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in the consolidated statements of operations become deductible expenses under applicable income tax laws, or loss or credit carryforwards are utilized. In assessing whether deferred tax assets may be realized, the Company considers whether it is more likely than not that some portion or all of deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. The Company makes estimates and judgments about its future taxable income based on assumptions that are consistent with its plans and estimates. Should the actual amounts differ from estimates, the amount of valuation allowance could be materially impacted. Any adjustment to the deferred tax asset valuation allowance would be recorded in the consolidated income statement for the periods in which the adjustment is determined to be required. |
Net Income (Loss) Per Ordinary Share | Net Income (Loss) Per Ordinary Share Basic earnings (losses) per share is computed by dividing net income (loss) available to ordinary shareholders by the weighted-average number of ordinary shares outstanding during the period. Diluted earnings (losses) per share is computed by dividing net income (loss) available to ordinary shareholders by the weighted-average number of ordinary shares outstanding during the period increased to include the number of additional ordinary shares that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, shares to be purchased under the Company’s employee stock purchase plan, unvested restricted stock and restricted stock units. The dilutive effect of potentially dilutive securities is reflected in diluted earnings (losses) per share by application of the treasury stock method. |
Comprehensive Income (Loss) | Comprehensive Income (Loss) Comprehensive income (loss) includes unrealized gains or losses from available-for-sale securities that are excluded from net income (loss). |
