Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Organization, Description of Business and Basis for Presentation | 1. Organization, Description of Business and Basis for Presentation Organization —Aquantia Corp. (together with its subsidiaries, the “Company”) was incorporated in Delaware on January 27, 2004. The Company is a leader in the design, development and marketing of advanced high-speed communications integrated circuits, or ICs, for Ethernet connectivity in the data center, enterprise infrastructure, access and automotive markets. Initial Public Offering — On November 7, 2017, the Company completed its initial public offering (“IPO”) of 7,840,700 shares of its common stock at the offering price of $9.00 per share, including 1,022,700 shares pursuant to the underwriters’ option to purchase additional shares of the Company’s common stock, resulting in net proceeds to the Company of $65.6 million after deducting underwriters' discounts and commissions of $4.9 million, but before deducting total offering expenses of approximately $5.7 million which were reclassified to additional paid-in capital upon completion of the IPO. Immediately prior to the closing of the IPO, all outstanding shares of the Company’s convertible preferred stock automatically converted into shares of its common stock and the Company’s convertible preferred stock warrants automatically converted into warrants to purchase common stock. The Company used $9.2 million and $0.3 million of the IPO proceeds, respectively, to repay the outstanding indebtedness under the Company’s loan from Pinnacle Ventures, L.L.C. and the termination fee for the line of credit from Hercules in 2017, respectively. Basis of Presentation and Principles of Consolidation — The accompanying unaudited condensed consolidated financial statements included herein have been prepared by us in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”), for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, normal recurring adjustments considered necessary for a fair presentation have been reflected in these condensed consolidated financial statements. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The condensed consolidated balance sheet as of December 31, 2017 has been derived from the audited financial statements for the fiscal year then ended included in the Company’s Annual Report on Form 10-K filed with the SEC on March 7, 2018 (the “2017 Annual Report on Form 10-K”), but does not include all of the information and notes required by U.S. GAAP for complete consolidated financial statements. The financial information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements as of and for the fiscal year ended December 31, 2017 and the related notes thereto included in the 2017 Annual Report on Form 10-Q. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies During the three months ended March 31, 2018, there have been no changes in our significant accounting policies as described in the Company’s 2017Annual Report on Form 10-K, except as discussed below: Recent Accounting Pronouncements — In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) Adopted Revenue Recognition — In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers” related to the recognition and reporting of revenue that establishes a comprehensive new revenue recognition model designed to depict the transfer of goods or services to a customer in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. The guidance allows for the use of either the full or modified retrospective transition method. This new standard was effective on January 1, 2018. Under the new standard, the Company used the modified retrospective method and recognizes all revenue on sales to distributors upon shipment and transfer of control (known as “sell-in” revenue recognition), rather than deferring recognition until distributor report that they have sold the product to their customers (known as “sell-through” revenue recognition). This change in methodology will cause a shift in the timing of when revenue is recognized for this class of customers comparing to prior periods. The Company provides some of its distributors rights that would result in a deferral of revenue under the revenue standards before the adoption. Accordingly, the Company recorded $0.1 million of deferred revenue balance to retained earnings upon adoption of this new standard on the Company’s condensed consolidated financial statements. As a result of the adoption, the Company revised its accounting policy for revenue recognition as detailed below: Revenue Recognition (applicable for periods commencing on or after January 1, 2018): Product revenues consist of sales to customers which are mainly comprised of end customers, their manufacturing subcontractors, and distributors. Revenue is recognized after the Company (a) identifies the contract with a customer, (b) identifies the performance obligations in the contract, (c) determines the transaction price, (d) allocates the transaction price to the performance obligations in the contract, and (e) satisfies the performance obligation when the control of products is transferred to the customer. The Company considers the purchase orders, which in some cases are governed by master sales agreements, to be the contract with its customers. In evaluating the existence of the contract, the Company considers various factors relative to the contract including the customer’s ability to pay amounts due under the contract. The Company is obligated to deliver a fixed number of products to its customers, each of which is distinct, and have been separately identified to be the performance obligations. The Company generally provides an assurance warranty that its products will substantially conform to the published specifications for twelve months from the date of shipment. The Company has not provided services in addition to the standard warranty. As such, the Company does not consider activities related to such warranty, if any, to be a separate performance obligation. In determining the transaction price, the Company considers the variability of the amount due under the contract including amounts subject to refund or adjustment when determining the net consideration to which the Company expects to be entitled within the contract. As the Company’s standard payment terms are less than one year, the Company has elected the practical expedient under the accounting guidance and does not assess whether the contract has a significant financing component. The Company allocates revenue to each product based on their relative standalone selling price. Frequently, the Company receives orders for products to be delivered over multiple dates that may extend across several reporting periods. The Company invoices for each delivery upon shipment and recognizes revenues for each distinct product delivered, assuming transfer of control has occurred. As scheduled delivery dates are within one year, under the optional exemption revenues allocated to future shipments of partially completed contracts are not disclosed. Sales to certain of end customers include limited rebates. The Company estimates these rebates, using historical volumes of such rebates, at the time revenue is recognized. Such rebates were not significant in any of the periods presented, and the differences between the actual amount of such rebates and our estimates also were not significant. Sales to most of our distributors are made under contracts that allow for pricing credits upon shipment to the end customer and rights of return for on hand inventory at the distributor. Under the accounting guidance, revenue is recognized at the point of transfer of control to the distributor, which typically occurs at the point of shipment. The Company adjusts the transaction price for any unprocessed claims and for future estimated pricing credits which is recorded in accrued liabilities on our condensed consolidated balance sheets. The adjustments for these estimates are recorded as a reduction to revenue in the same period when the related revenue is recorded and is calculated based on an analysis of the historical actual claims received, both in aggregate and at a distributor level to the extent that it is probable that a significant future reversal of revenue will not occur. Historically, adjustments for actual pricing credits and product returns have not been significantly differed from the amounts estimated by the Company. As of March 31, 2108, the Company has recorded an accrued liability of $0.4 million relative to the above adjustments to transaction price. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | 5. Fair Value Measurements The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities which are required to be recorded at fair value, the Company considers the principal or most advantageous market in which to transact and the market-based risk. The Company applies fair value accounting for all financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. Level 1 liabilities consist of accounts payable, accrued expense and long-term debt. The carrying amounts of accounts receivable, prepaid expenses, accounts payable and accrued liabilities approximate fair value due to the short-term nature of these items. Based on the borrowing rates currently available to the Company for debt with similar terms, the carrying value of the term debt approximates fair value as well. The Company categorizes assets and liabilities recorded at fair value based upon the level of judgment associated with inputs used to measure their fair value. The categories are as follows: Level 1 —Observable inputs, such as quoted prices in active markets for identical, unrestricted assets, or liabilities. Level 2 —Quoted prices for similar assets or liabilities, or inputs other than quoted prices in active markets that are observable either directly or indirectly. Level 3 —Unobservable inputs in which there is little or no market data, which require the Company to develop its own assumptions about the assumptions market participants would use in pricing the asset or liability. Valuation techniques include use of option-pricing models, discounted cash flows models, and similar techniques. The hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. The following tables represent the Company’s financial assets and financial liabilities measured at fair value on a recurring basis categorized by the fair value hierarchy as of March 31, 2018 and December 31, 2017 (in thousands): As of March 31, 2018 Level 1 Level 2 Level 3 Total Financial asset— available-for-sales securities Money market funds $ 185 $ — $ — $ 185 Commercial Paper — 18,389 — 18,389 Corporate bonds — 39,550 — 39,550 U.S. government securities — 2,488 — 2,488 Total financial asset—available-for-sales securities $ 185 $ 60,427 $ — $ 60,612 As of December 31, 2017 Level 1 Level 2 Level 3 Total Financial asset— available-for-sales securities Money market funds $ 1,269 $ — $ — $ 1,269 Commercial paper — 13,916 — 13,916 Corporate bonds — 36,453 — 36,453 U.S. government securities — 2,485 — 2,485 Total financial asset—available-for-sales securities $ 1,269 $ 52,854 $ — $ 54,123 There were no transfers within the hierarchy during the three months ended March 31, 2018 and 2017. |

Commitments and Contingencies | 6. Commitments and Contingencies Lease and purchase obligations— The Company leases office and research facilities under operating leases for its U.S. headquarters and international locations that expire at various dates through March 2024. Under any lease agreement that contains escalating rent provisions, lease expense is recorded on a straight-line basis over the lease term. Rent expense for the three months ended March 31, 2018 and 2017 was $0.3 million and $0.2 million, respectively. In addition, the Company has purchase obligations which included agreements and issued purchase orders containing non-cancelable payment terms to purchase goods and services. As of March 31, 2018, future minimum operating lease payments and purchase obligations are as follows (in thousands): Total Operating Purchase Lease and Purchase Leases Obligations Obligations 2018 (remaining) $ 644 $ 10,494 $ 11,138 2019 1,488 2,289 3,777 2020 1,535 1,549 3,084 2021 2,034 — 2,034 2022 and thereafter 4,299 — 4,299 Total $ 10,000 $ 14,332 $ 24,332 Litigation— The Company accrues for contingencies when it believes that a loss is probable and that it can reasonably estimate the amount of any such loss and the Company has made an assessment of the probability of incurring any such losses and whether or not those losses are estimable. Although the Company is not currently subject to any litigation, and the Company is not aware of any litigation currently threatened against it, the Company may be subject to legal proceedings, claims and litigation, including intellectual property litigation, arising in the ordinary course of business. Such matters are subject to many uncertainties and outcomes and are not predictable with assurance. The Company accrues amounts that it believes are adequate to address any liabilities related to legal proceedings and other loss contingencies that it believes will result in a probable loss that is reasonably estimable. To the extent there is a reasonable possibility that a loss exceeding amounts already recognized may be incurred and the amount of such additional loss would be material, the Company will either disclose the estimated additional loss or state that such an estimate cannot be made. The Company does not currently believe that it is reasonably possible that losses in connection with litigation arising in the ordinary course of business would be material. Indemnification— Under the indemnification provisions of the Company’s standard sales-related contracts, the Company agrees to defend its customers against third-party claims asserting infringement of certain intellectual property rights, which may include patents, copyrights, trademarks, or trade secrets, and to pay judgments entered on such claims. Certain agreements include indemnification provisions that could potentially expose the Company to losses in excess of the amount received under the agreement. In addition, the Company indemnifies its directors and certain of its officers while they are serving in good faith in such capacities. To date, the Company has not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As of March 31, 2018 and December 31, 2017, no liability associated with such indemnifications had been recorded. |

Shareholders' Equity and Share-based Compensation | 7 . Shareholder’s Equity and Share-based Compensation The Company’s certificate of incorporation, as of March 31, 2018 and December 31, 2017, authorized the Company to issue up to 400,000,000 shares of common stock and 10,000,000 shares of preferred stock, each at $0.00001 par value per share, respectively. As of March 31, 2018, no preferred stock was outstanding. Each share of common stock is entitled to one vote. The holders of common stock are also entitled to receive dividends out of funds legally available. No dividends have been declared to date. 2015 Equity Incentive Plan and 2004 Equity Incentive Plan Under the Company’s 2015 Equity Incentive Plan and 2004 Equity Incentive Plan, shares of common stock were reserved for the issuance of incentive stock options (“ISO”); nonstatutory stock options (“NSO”); or the sales of restricted common stock to employees, officers, directors, and consultants of the Company. The exercise price of an option is determined by the board of directors when the option is granted and may not be less than 85% of the fair market value of the shares on the date of grant, provided that the exercise price of an ISO is not less than 100% of the fair market value of the shares on the date of grant and the exercise price of any option granted to a 10% stockholder is not less than 110% of the fair market value of the shares on the date of grant. ISOs granted under the Plan generally vest 25% after the completion of 12 months of service and the balance in equal monthly installments over the next 36 months of service and expire 10 years from the grant date. NSOs vest as per the specific agreement and expire 10 years from the date of grant. The Plan allows for early exercise of options prior to full vesting as determined by the board of directors and set forth in the stock option agreements governing such options. Exercises of unvested options are subject to repurchase by the Company at not less than the original exercise price upon termination of employment. 2017 Equity Incentive Plan In November 2017, the Company adopted the 2017 Equity Incentive Plan, or 2017 Plan, and all shares reserved for grant under the 2015 Equity Incentive Plan and 2004 Equity Incentive Plan were cancelled. The 2017 Plan had 1,618,735 common shares reserved, plus any shares subject to outstanding stock options or other stock awards that were granted under the 2015 Equity Incentive Plan and 2004 Equity Incentive Plan that were forfeited, terminate, expire or are otherwise not issued. In addition, the shares reserved under the 2017 Plan will automatically increase on the first day of each calendar year, beginning on January 1, 2018 and ending on January 1, 2027, by an amount equal to 5% of the total number of shares of the Company’s capital stock outstanding on the last day of the calendar month before the date of the automatic increase, or a lesser number of shares determined by the board of |

As of December 31, 2017, approximately $4.8 million of unrecognized stock compensation costs related to awards were expected to be recognized over a weighted-average period of 3.1 years. The aggregate intrinsic value of options exercised during the three months ended March 31, 2018 was $0.1 million. The aggregate intrinsic value of options exercised during the year ended December 31, 2017 was $1.6 million. There were no options granted during the three months ended March 31, 2018. The weighted-average grant-date fair value of options granted during the year ended December 31, 2017 was $2.94 per share. The calculated fair value of option grants was estimated using the Black-Scholes model with the following assumptions for which options were granted: Three Months Ended March 31, 2018 2017 Risk-free interest rate — 1.97% - 2.40% Expected term — 6.1 - 9.6 yrs Expected dividends — 0% Volatility — 30% Restricted Stock Unit Awards The Company grants restricted stock units (RSU) to employees under the 2017 Plan. RSUs granted typically vest ratably over a four-year period and are converted into shares of the Company’s common stock upon vesting on a one-for-one basis subject to the employee’s continued service to the Company over that period. The fair value of RSUs is determined using the fair value of the Company’s common stock on the date of the grant, reduced by the discounted present value of dividends expected to be declared before the awards vest. Compensation expense is recognized on a straight-line basis over the requisite service period of each grant. Each RSU award granted from the 2017 Plan will reduce the number of shares available for issuance under the 2017 Plan by one share. For the three months ended March 31, 2018, unamortized compensation expense related to RSU was approximately $1.9 million, to be recognized over 2.5 years. For the year ended December 31, 2017, unamortized compensation expense related to RSU was approximately $0.4 million, to be recognized over 1.8 years. Activity under the Company’s RSU is set forth below : Number of Shares Balance—December 31, 2017 35,029 Granted 102,500 Released — Canceled — Balance—March 31, 2018 137,529 Employee Stock Purchase Plan Concurrent with the completion of the IPO in November 2017, the Company adopted the 2017 Employee Stock Purchase Plan, or ESPP. The ESPP authorizes the issuance of 647,494 shares of common stock outstanding under purchase rights granted to its employees. In addition, the shares reserved under the ESPP Plan will automatically increase on the first day of each calendar year, beginning on January 1, 2018 and ending on January 1, 2027, by the lesser of (i) an amount equal to 2% of the total number of shares of the Company’s capital stock outstanding on the last day of the calendar month before the date of the automatic increase, (ii) 1,000,000 shares of common stock, and (iii) a lesser number of shares determined by the board of directors prior to the date of such automatic increase. The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to any plan limitations. The ESPP generally provides for offering periods and purchase periods every six months, and at the end of each purchase period, employees are able to purchase shares at 85% of the lower of the fair market value of the Company’s common stock on the first trading day of the purchase period or on the last trading day of the offering period. Since the ESPP was established in November 2017, no shares were issued as of December 31, 2017. Shares expected to be issued under the ESPP were 226,000 for the offering period as of December 31, 2017. The calculated fair value of the shares under the ESPP was estimated using the Black-Scholes model with the following assumptions: risk-free interest rate of 1.31%, expected term of 0.5 year, expected dividends of 0% and volatility of 22%. For the three months ended March 31, 2018, unamortized compensation expense related to ESPP was approximately $0.1 million, to be recognized over approximately two months. For the year ended December 31, 2017, unamortized compensation expense related to ESPP was approximately $0.5 million, to be recognized over approximately five months. The Company uses the straight-line vesting attribution method to record stock-based compensation expense. Stock-based compensation expense recognized in the consolidated statements of operations and comprehensive loss for options, restricted stock units and ESPP was as follows (in thousands): Three Months Ended March 31, 2018 2017 Cost of revenue $ 25 $ 7 Research and development 573 132 Sales and marketing 111 27 General and administrative 269 76 Total $ 978 $ 242 No income tax benefit associated with stock-based compensation expense was recognized in the condensed consolidated statements of operations and comprehensive loss for the three months ended March 31, 2018 and 2017. |

Income Tax Disclosure [Abstract] | |
Income Taxes | 9. Income Taxes The Company recorded an income tax benefit of $0.1million and provision of $0.2 million for the three months ended March 31, 2018 and 2017, respectively. The income tax benefit for the three months ended March 31, 2018 consisted primarily of a credit to foreign jurisdiction. As of March 31, 2018, based on the available objective evidence, management believes it is more likely than not that the net deferred tax assets will not be realized for federal and state purposes. Accordingly, management has applied a full valuation allowance against its federal and state net deferred tax assets as of March 31, 2018. A release of such valuation allowance could cause a material increase to income in the period such determination is made. Internal Revenue Code Section 382 and similar California rules place a limitation on the amount of taxable income that can be offset by NOL carryforwards after a change in control (generally greater than 50% change in ownership). Generally, after a control change, a corporation cannot deduct NOL carryforwards in excess of the Section 382 limitations. Due to these provisions, utilization of NOL and tax credit carryforwards may be subject to annual limitations regarding their utilization against taxable income in future periods. The Company completed Section 382 analysis in 2016 and determined ownership changes occurred in July 2005, November 2009 and August 2017, which resulted in reductions to the U.S. federal and California net operating losses of $34.9 million and $24.1 million, respectively, and U.S. federal research and development credits by $1.8 million. Since no deferred tax assets have been recognized on our balance sheet related to our NOLs and tax credits, as they are fully reserved by a valuation allowance, there was no impact to the tax provision. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Act”). The Act makes broad and complex changes to the U.S. tax code including, but not limited to: (1) reducing the U.S. federal corporate tax rate from 35 percent to 21 percent; (2) requiring companies to pay a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries; (3) generally eliminating U.S. federal income taxes on dividends from foreign subsidiaries; (4) requiring current inclusion in U.S. federal taxable income of certain earnings of controlled foreign corporations; (5) eliminating the corporate alternative minimum tax, or AMT, and changing how existing AMT credits can be realized; (6) creating the base erosion anti-abuse tax, or BEAT, a new minimum tax; (7) creating a new limitation on deductible interest expense; and (8) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017. As of December 31, 2017, the Company’s remeasured certain deferred tax assets and liabilities based on rates at which they are expected to reverse in the future, which is generally 21%. The rate reduction would generally take effect on January 1, 2018. Consequently, any changes in the U.S. corporate income tax rate will impact the carrying value of the deferred tax assets. Under the new corporate income tax rate of 21%, U.S. federal and state deferred tax assets decreased by approximately $15.7 million as of December 31, 2017 and the valuation allowance decreased by approximately the same amount. Due to the valuation allowance on the deferred tax assets, the provisional amount recorded related to the remeasurement was zero. As of December 31, 2017, the Company's foreign subsidiaries are in a cumulative deficit. Therefore, the one-time transition tax on deemed repatriation of previously untaxed accumulated earnings and profits of foreign subsidiaries has minimal impact on the Company. Undistributed earnings of foreign subsidiaries are determined to be reinvested indefinitely. Accounting for the transition tax and the conclusion on the Company’s indefinite reinvestment have been completed pursuant to the requirements of the Act. The SEC staff issued Staff Accountant Bulletin No. 118, or SAB 118, which provides guidance on accounting for the tax effects of the Act. SAB 118 provides a measurement period that should not extend beyond one year from the Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Act. As noted above, the Company has recorded a provisional amount associated with the deferred tax assets and related valuation allowance as of March 31, 2018. At March 31, 2018, the Company is still analyzing certain aspects of the Act including (a) provisions for Global Intangible Low-Taxed Income, or GILTI, wherein taxes on foreign income are imposed in excess of a deemed return on tangible assets of foreign corporations (including related accounting policy elections) and (b) state tax implications of the Act. |

Basic and diluted net loss per share is presented in conformity with the two-class method required for participating securities. Prior to the IPO, the holders of the Company’s convertible preferred stock were entitled to receive non-cumulative dividends, payable prior and in preference to any dividends on shares of the common stock. Any additional dividends would be distributed among the holders of convertible preferred stock and common stock pro rata, assuming the conversion of all convertible preferred stock into common stock. After to the IPO, all convertible preferred stocks were converted to common stock and the Company has one class of stock issued and outstanding. The following potentially dilutive securities outstanding have been excluded from the computation of diluted weighted-average shares outstanding because such securities have an antidilutive impact due to losses reported (in common stock equivalent shares): As of As of March 31, December 31, 2018 2017 Stock options to purchase common stock 3,637,248 3,733,544 Common stock warrants 498,419 584,148 Total 4,135,667 4,317,692 |

Concentrations | 12. Concentrations Credit —Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company’s cash equivalents consist of cash and money market accounts with a financial institution that management believes to be of high-credit quality; however, at times, balances exceed federally insured limits. Amounts held on deposit at financial institutions in excess of Federal Deposit Insurance Corporation-insured amounts were $0.4 million and $0.9 million as of March 31, 2018 and December 31, 2017, respectively. Significant Customers —Credit risk with respect to accounts receivable is concentrated with two large customers that contribute a majority of the Company’s business and is mitigated by a relatively short collection period. Collateral is not required for accounts receivable. The fair value of accounts receivable approximates their carrying value. Revenue and accounts receivable concentrated with significant customers and their manufacturing subcontractors as a percentage of accounts receivable and total revenue were as follows: As of As of March 31, December 31, 2018 2017 Accounts Receivable: Customer A 36 % 49 % Customer B 49 34 Three Months Ended March 31, 2018 2017 Revenue: Customer A 55 % 63 % Customer B 28 26 |

Recent Accounting Pronouncements | Recent Accounting Pronouncements — In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) Adopted |
Revenue Recognition | Revenue Recognition — In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers” related to the recognition and reporting of revenue that establishes a comprehensive new revenue recognition model designed to depict the transfer of goods or services to a customer in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. The guidance allows for the use of either the full or modified retrospective transition method. This new standard was effective on January 1, 2018. Under the new standard, the Company used the modified retrospective method and recognizes all revenue on sales to distributors upon shipment and transfer of control (known as “sell-in” revenue recognition), rather than deferring recognition until distributor report that they have sold the product to their customers (known as “sell-through” revenue recognition). This change in methodology will cause a shift in the timing of when revenue is recognized for this class of customers comparing to prior periods. The Company provides some of its distributors rights that would result in a deferral of revenue under the revenue standards before the adoption. Accordingly, the Company recorded $0.1 million of deferred revenue balance to retained earnings upon adoption of this new standard on the Company’s condensed consolidated financial statements. As a result of the adoption, the Company revised its accounting policy for revenue recognition as detailed below: Revenue Recognition (applicable for periods commencing on or after January 1, 2018): Product revenues consist of sales to customers which are mainly comprised of end customers, their manufacturing subcontractors, and distributors. Revenue is recognized after the Company (a) identifies the contract with a customer, (b) identifies the performance obligations in the contract, (c) determines the transaction price, (d) allocates the transaction price to the performance obligations in the contract, and (e) satisfies the performance obligation when the control of products is transferred to the customer. The Company considers the purchase orders, which in some cases are governed by master sales agreements, to be the contract with its customers. In evaluating the existence of the contract, the Company considers various factors relative to the contract including the customer’s ability to pay amounts due under the contract. The Company is obligated to deliver a fixed number of products to its customers, each of which is distinct, and have been separately identified to be the performance obligations. The Company generally provides an assurance warranty that its products will substantially conform to the published specifications for twelve months from the date of shipment. The Company has not provided services in addition to the standard warranty. As such, the Company does not consider activities related to such warranty, if any, to be a separate performance obligation. In determining the transaction price, the Company considers the variability of the amount due under the contract including amounts subject to refund or adjustment when determining the net consideration to which the Company expects to be entitled within the contract. As the Company’s standard payment terms are less than one year, the Company has elected the practical expedient under the accounting guidance and does not assess whether the contract has a significant financing component. The Company allocates revenue to each product based on their relative standalone selling price. Frequently, the Company receives orders for products to be delivered over multiple dates that may extend across several reporting periods. The Company invoices for each delivery upon shipment and recognizes revenues for each distinct product delivered, assuming transfer of control has occurred. As scheduled delivery dates are within one year, under the optional exemption revenues allocated to future shipments of partially completed contracts are not disclosed. Sales to certain of end customers include limited rebates. The Company estimates these rebates, using historical volumes of such rebates, at the time revenue is recognized. Such rebates were not significant in any of the periods presented, and the differences between the actual amount of such rebates and our estimates also were not significant. Sales to most of our distributors are made under contracts that allow for pricing credits upon shipment to the end customer and rights of return for on hand inventory at the distributor. Under the accounting guidance, revenue is recognized at the point of transfer of control to the distributor, which typically occurs at the point of shipment. The Company adjusts the transaction price for any unprocessed claims and for future estimated pricing credits which is recorded in accrued liabilities on our condensed consolidated balance sheets. The adjustments for these estimates are recorded as a reduction to revenue in the same period when the related revenue is recorded and is calculated based on an analysis of the historical actual claims received, both in aggregate and at a distributor level to the extent that it is probable that a significant future reversal of revenue will not occur. Historically, adjustments for actual pricing credits and product returns have not been significantly differed from the amounts estimated by the Company. As of March 31, 2108, the Company has recorded an accrued liability of $0.4 million relative to the above adjustments to transaction price. |
