Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Business and Basis of Presentation | Business and Basis of Presentation Transphorm, Inc. (“Parent”) develops gallium nitride (“GaN”) semiconductor components used in power conversion and is headquartered in Goleta, California. Parent’s wholly owned-subsidiary, Transphorm Technology, Inc. (“Transphorm Technology”), was incorporated in the State of Delaware on February 22, 2007. Throughout these notes, “the Company,” “Transphorm,” “we,” “us” and “our” refer to Parent and its direct and indirect wholly-owned subsidiaries. Transphorm Technology and its subsidiaries hold all material assets and conduct all business activities and operations of the Company. Transphorm Technology’s activities to date have been primarily performing research and development, establishing manufacturing infrastructure, market sampling, product launch, hiring personnel, and raising capital to support and expand these activities. Transphorm Japan, Inc. was established in Japan in February 2014 to secure Transphorm’s production capacity and establish a direct presence in Asian markets. Transphorm Aizu, Inc. was established in Japan to manage the financial transactions around Aizu Fujitsu Semiconductor Wafer Solution Limited, Transphorm’s non-controlling joint venture wafer fabrication facility located in Aizu Wakamatsu, Japan (“Aizu”). Transphorm Japan Epi, Inc. was established in Japan in 2019 to enable the operational capacity of the reactors held in Aizu. Change in Fiscal Year End On April 20, 2021, we changed our fiscal year from the period beginning on January 1 and ending on December 31 to the period beginning on April 1 and ending on March 31 of each year, effective immediately. Accordingly, we filed a Transition Report on Form 10-K on June 24, 2021 to include audited consolidated financial information for the transition period from January 1, 2021 through March 31, 2021. Reverse Merger On February 12, 2020, our wholly-owned subsidiary, Peninsula Acquisition Sub, Inc., a corporation formed in the State of Delaware (“Acquisition Sub”), merged with and into Transphorm Technology (formerly known as Transphorm, Inc.), the corporate existence of Acquisition Sub ceased, and Transphorm Technology became our wholly-owned subsidiary (such transaction, the “Merger”). As a result of the Merger, we acquired the business of Transphorm Technology. The Merger was effective as of February 12, 2020, upon the filing of a certificate of merger with the Secretary of State of the State of Delaware. Immediately after completion of the Merger, we adopted Transphorm Technology’s former company name, “Transphorm, Inc.”, as our company name. The Merger was treated as a recapitalization and reverse acquisition for financial reporting purposes, and Transphorm Technology is considered the acquirer for accounting purposes. As a result of the Merger and the change in our business and operations, a discussion of the past financial results of our predecessor, Peninsula Acquisition Corporation, is not pertinent, and under applicable accounting principles, the historical financial results of Transphorm Technology, the accounting acquirer, prior to the Merger are considered our historical financial results. At the effective time of the Merger, (i) each share of Transphorm Technology’s common stock issued and outstanding immediately prior to the closing of the Merger was converted into the right to receive (a) 0.08289152527 shares of our common stock (in the case of shares held by accredited investors) or (b) $4.00 multiplied by 0.08289152527 (in the case of shares held by unaccredited investors), with the actual number of shares of our common stock issued to the former holders of Transphorm Technology’s common stock equal to 4,171,571, (ii) 51,680,254 shares of Transphorm Technology’s Series 1 preferred stock issued and outstanding immediately prior to the closing of the Merger were converted into 12,433,953 shares of our common stock, (iii) 38,760,190 shares of Transphorm Technology’s Series 2 preferred stock issued and outstanding immediately prior to the closing of the Merger were converted into 7,499,996 shares of our common stock, and (iv) 31,850,304 shares of Transphorm Technology’s Series 3 preferred stock issued and outstanding immediately prior to the closing of the Merger were converted into 4,000,000 shares of our common stock. As a result, 28,105,520 shares of our common stock were issued to the former holders of Transphorm Technology’s issued and outstanding capital stock after adjustments due to rounding for fractional shares. Immediately prior to the effective time of the Merger, an aggregate of 682,699 shares of our common stock, owned by the stockholders of Peninsula Acquisition Corporation prior to the Merger, were forfeited and cancelled. In addition, pursuant to the Merger Agreement, (i) options to purchase 29,703,285 shares of Transphorm Technology’s common stock issued and outstanding immediately prior to the closing of the Merger under Transphorm Technology’s 2007 Stock Plan (the “2007 Plan”) and 2015 Equity Incentive Plan (the “2015 Plan”) were assumed and converted into options to purchase 2,461,923 shares of our common stock, (ii) warrants to purchase 186,535 shares of Transphorm Technology’s common stock issued and outstanding immediately prior to the closing of the Merger were assumed, amended and converted into warrants to purchase 15,461 shares of our common stock, and (iii) Transphorm Technology’s outstanding convertible promissory note was amended to be convertible at the option of the holder, into shares of our common stock at a conversion price of $5.12 per share. On October 4, 2021, the promissory note of $15.6 million, consisting of an outstanding principal amount of $15.0 million plus accrued but unpaid interest of $600 thousand, was further amended to reduce the conversion price from $5.12 per share to $5.00 per share and converted into an aggregate of 3,120,000 shares of our common stock. See Note 13 - Fair Value Measurements, Note 9 - Debts and Note 11 - Stockholders’ Equity (Deficit). All per share and share amounts for all periods presented have been retroactively adjusted to reflect the effect of the Merger. Liquidity and Capital Resources The Company’s ability to sustain operations is dependent mainly on its ability to successfully market and sell its products and its ability to raise capital through additional financings until it is able to achieve profitability with positive cash flows. The Company currently incurs and historically has incurred losses from operations and expects to do so in the foreseeable future. During the year ended March 31, 2022, the Company used $19.7 million of cash in operations. Although the Company expects to continue to incur losses and sustain negative cash flows from operating activities, during the year ended March 31, 2022, the Company raised gross proceeds of $50.9 million from private placements. Consequently, the Company has sufficient resources to fund its operations for the next twelve months from the date of this filing. The Company may need to continue to raise additional capital to finance its losses and negative cash flows from operations beyond the next twelve months and may continue to be dependent on additional capital raises. Impact of COVID-19 on Our Business The COVID-19 pandemic has adversely disrupted and will further disrupt the operations at certain of our customers, partners, suppliers and other third-party providers for an uncertain period of time, including as a result of travel restrictions, adverse effects on budget planning processes, business deterioration, and/or business shutdowns, all of which has impacted our business and results of operations. Some of our customers have experienced delays in their internal development programs and design cycles with our GaN products due to the effects of COVID-19, which have led to postponements of their orders of our products and postponements of determinations that our products will be used in their designs for new products under development with corresponding delays in their market introduction and our revenues. While the impact of COVID-19 on our business and results of operations has not been significant to date, and we do not expect to see any significant impact in the near term, any future impact of COVID-19 cannot be predicted with certainty and may make it more difficult or preclude us from raising additional capital, increase our costs of capital and otherwise adversely affect our business, results of operations, financial condition and liquidity. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting PoliciesPrinciples of Consolidation The consolidated financial statements include the accounts of the Parent and its wholly-owned subsidiaries, Transphorm Technology, Transphorm Japan, Inc., Transphorm Japan Epi, Inc. and Transphorm Aizu, Inc. Upon consolidation, all significant intercompany accounts and transactions have been eliminated. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Management bases its estimates and assumptions on historical experience, knowledge of current conditions, and its belief of what could occur in the future, given available information. Actual results could differ from those estimates, and such differences could be material to the consolidated financial statements. Estimates are used for, but not limited to, the determinations of fair value of stock awards and promissory notes, accrual of expenses, revenue recognition, allowance for doubtful accounts, inventory reserve, and useful lives for property and equipment. Cash, Cash Equivalents and Restricted Cash The Company considers all highly-liquid investments with original maturities of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents consist principally of bank deposits and money market funds. Restricted cash of $575 thousand as of March 31, 2022 consists of $500 thousand of cash in current asset and $75 thousand of long-term deposit in other assets. Restricted cash of $75 thousand as of March 31, 2022 and 2021 consists of long-term deposit in other assets. Foreign Currency Risk The Company is exposed to foreign currency risk due to its operations in Japan (Yen). Assets and liabilities of the operations are re-measured into U.S. currency at exchange rates in effect at the balance sheet dates through the consolidated statements of comprehensive income. Gains or losses resulting from foreign currency transactions are re-measured using the rates on the dates on which those elements are recognized during the period and are included in other income or expense in the consolidated statements of operations. Changes in the value of our cash balance due to fluctuations in foreign exchange rate are presented on the consolidated statements of cash flows as effect of foreign exchange rate changes on cash, cash equivalents and restricted cash. As of March 31, 2022 and March 31, 2021, the Company had foreign cash and cash equivalents of $66 thousand and $444 thousand, respectively, which represented 0.2 percent and 4.7 percent, respectively, of total cash and cash equivalents. Concentrations of Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents. The Company is exposed to credit risk in the event of default by the financial institution holding its cash. The Company’s investment policy restricts investments to high-quality investments and limits the amounts invested with any one issuer, industry or geographic area. Risks associated with cash holdings in excess of insured limits are mitigated by banking with high-quality institutions. To date, the Company has not experienced any significant losses on its cash and cash equivalents. The Company periodically evaluates the relative credit standing of these financial institutions. The Company is subject to risks common in the power conversion components industry, including, but not limited to, technological obsolescence, dependence on key personnel, market acceptance of its products, the successful protection of its proprietary technologies, compliance with government regulations, and the possibility of not being able to obtain additional financing when needed. Comprehensive Loss Comprehensive loss is comprised of net loss and other comprehensive loss. Other comprehensive loss includes the impact of foreign currency translation adjustments. Accounts Receivable Accounts receivable are analyzed and allowances for uncollectible accounts are recorded, as required. Provisions for uncollectible accounts, if any, are recorded as bad debt expense and included in general and administrative expenses in the accompanying consolidated statements of operations. The process for determining the appropriate level of allowances for doubtful accounts involves judgment, and the Company considers such factors as the age of the underlying receivables, historical and projected collection trends, the composition of outstanding receivables, current economic conditions and regulatory changes. An account is fully reserved when reasonable collection efforts have been unsuccessful and it is probable that the receivable will not be recovered. No provision for doubtful accounts was recorded for the year ended March 31, 2022 as substantially all of the accounts receivables were collected subsequently. Recovery from doubtful accounts amounted to $48 thousand for the three months ended March 31, 2021. Provision for doubtful accounts amounted to $110 thousand for the year ended December 31, 2020. Inventory Inventory is stated at the lower of cost (first-in, first-out method) or net realizable value. The Company periodically reviews the value of items in inventory and records write-downs or write-offs based on its assessment of slow moving or obsolete inventory. The Company maintains an inventory reserve for obsolete inventory and generally makes inventory value adjustments against the inventory reserve. Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is determined using the straight-line method over the estimated useful lives of the respective assets, generally ranging from three The Company evaluates the carrying amount of its property and equipment whenever events or changes in circumstances indicate that the assets may not be recoverable. An impairment loss would be recognized when estimated future cash flows expected to result from the use of an asset or asset group and its eventual disposition are less than the carrying amount of the asset or asset group. To date, there have been no such impairment losses. Goodwill Goodwill arose for the acquisition of a business in February 2014 based in Japan and was accounted for as the purchase of a business. Goodwill generated from business combinations and deemed to have indefinite lives are not subject to amortization and instead are tested for impairment at least annually in December unless certain events occur or circumstances change. Goodwill represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. We test for goodwill impairment annually, on March 31, or earlier if events or changes in circumstances indicate goodwill might possibly be impaired. Impairment exists when the carrying value of the goodwill exceeds its implied fair value. An impairment loss would be recognized in an amount equal to that excess as a charge to operations in the consolidated statements of operations. For the year ended March 31, 2022, the three months ended March 31, 2021, and the year ended December 31, 2020, no impairment charge was recorded related to goodwill. Intangible Assets Intangible assets that are not considered to have an indefinite useful life are amortized over their estimated useful lives, which generally range from three estimated remaining useful lives of intangible assets and whether events or changes in circumstances warrant a revision to the remaining periods of amortization. If it is determined that the carrying values might not be recoverable based upon the existence of one or more indicators of impairment, the Company performs a test for recoverability using various methodologies, such as the income approach or cost approach, to determine the fair value of intangible assets depending upon the nature of the assets. If assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds their respective fair values. For the year ended March 31, 2022, the three months ended March 31, 2021 and the year ended December 31, 2020, no impairment charges were recorded related to intangible assets. Revenue Recognition The Company derives its revenues from sales of high-powered GaN-based products manufactured utilizing the Company’s proprietary and patented epiwafer technology and wafer fabrication and other assembly processes, sales of GaN epiwafers for the radio frequency (“RF”) and power markets, and sales of licenses to use such patented proprietary technology, as well as enabling EPI wafer growth services and products to our strategic partners. Revenues are recognized when control of these products or licenses are transferred to the Company’s customers in an amount that reflects the consideration it expects to be entitled to in exchange for those products and licenses. Sales and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense. The Company does not have any significant financing components associated with its revenue contracts, as payment is received at or shortly after the point of sale. Disaggregation of Revenue from Contracts with Customers Revenue consists of perpetual licensing revenue, government contract revenue from our contract with the U.S. Navy and product sales, with applicable performance obligations satisfied at a point in time. Products are sold to distributors and end-users in various sectors such as, but not limited to, the automotive, gaming, industrial, IT, and consumer products industries. As part of the multi-element commercial arrangement executed with Nexperia on April 4, 2018 (see Note 3 - Nexperia Arrangement), the Company agreed to grant Nexperia the perpetual exclusive right to use the Company’s existing Gen-3 manufacturing process technology. License fees are received upon satisfaction of contractual milestones and recognized upon delivery of the perpetual license or transferred technology without any remaining performance obligations. The Company recognized $8.0 million of perpetual licensing revenue for the year ended March 31, 2022. No perpetual licensing revenue was recognized for the three months ended March 31, 2021. The Company recognized $5.0 million of perpetual licensing revenue for the year ended December 31, 2020. In December 2020, the Company entered into a cooperation and development agreement with Yaskawa Electric Corporation (“Yaskawa”), pursuant to which Yaskawa agreed to provide $4.0 million over approximately three years to fund development activities related to industrial power conversion applications, with an initial focus on servo motor drive applications. Yaskawa provided payments of $1.0 million and $750 thousand of this $4.0 million commitment in December 2020 and July 2021, respectively. The Company evaluated and concluded that the deliverables are the same and nature of the services to be provided to Yaskawa will be consistent over the period of approximately three years. Accordingly, with respect to the $1.8 million payment, the Company recognized $1.1 million as revenue for the year ended March 31, 2022, $333 thousand as revenue for the three months ended March 31, 2021 and $333 thousand as revenue for the year ended December 31, 2020. The Company also recorded $375 thousand as revenue for services rendered but not billed for the year ended March 31, 2022. Government contract revenues are principally generated under research and development contracts. Contract revenues are derived primarily from research contracts with agencies of the U.S. government. We believe credit risk related to accounts receivable arising from such contracts is minimal. These contracts may include cost-plus fixed fee and fixed price terms. All payments to us for work performed on contracts with agencies of the U.S. government are subject to adjustment upon audit by the Defense Contract Audit Agency. The contract’s expiration dates were initially March and June 2022, but such dates were subsequently extended to June and December 2022, respectively. The Company received new government authorized rates for billing purposes which allowed for retroactive application since inception. The cumulative impact of this rate change as of March 31, 2022 was $423 thousand, of which $(83) thousand and $505 thousand were recorded in the three months ended March 31, 2021 and year ended December 31, 2021, respectively. On February 1, 2022, the Company received new government authorized rates which allowed for retroactive application effective for the year ended December 31, 2020. The Company will use the new approved rates on a go-forward basis. Performance Obligations For performance obligations related to the sale of products, control transfers to the customer at a point in time. The Company’s principal terms of sale are free on board shipping or destination and the Company transfers control and records revenue for product sales upon shipment or delivery to the customer, respectively. For performance obligations related to the licensing of patented technology in perpetuity, control also transfers to the customer at a point in time. The Company transfers control and records revenue for licensing fees once the Company has (i) provided or otherwise makes available the patented technology to the customer and (ii) the customer is able to use and benefit from the patented technology. Variable Consideration The nature of the Company’s arrangement with Nexperia gives rise to variable consideration in the form of milestone and royalty payments. The royalties qualify for the sales and usage-based royalty exception, as the license of intellectual property is the predominant item to which the royalty relates and are recognized upon the subsequent sale occurring. The variable amounts are received upon satisfaction of contractually agreed upon development targets and sales volume. Research and Development The Company is a party to research grant contracts with the U.S. government for which the Company is reimbursed for specified costs incurred for its research projects. These projects include energy saving initiatives for which the U.S. government offers reimbursement funds. Such reimbursements are recorded as an offset to research and development expenses when the related qualified research and development expenses are incurred. Reimbursable costs are recognized in the same period the costs are incurred up to the limit of approved funding amounts on qualified expenses. Grant reimbursement of $345 thousand, $42 thousand and $426 thousand was recorded as an offset to research and development expense for the year ended March 31, 2022, the three months ended March 31, 2021 and the year ended December 31, 2020. Stock-Based Compensation All share-based payments, including grants of stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”), are measured at the fair value of the share-based awards on the grant date and recognized over their respective vesting periods, which is generally one The Black-Scholes-Merton option pricing model requires inputs such as the fair value of common stock on date of grant, expected term, expected volatility, dividend yield, and risk-free interest rate. Further, the forfeiture rate also affects the amount of aggregate compensation expense. These inputs are subjective and generally require significant analysis and judgment to develop. Volatility data is obtained from a study of publicly traded industry peer companies. The forfeiture rate is derived primarily from the Company’s historical data, and the risk-free interest rate is based on the yield available on U.S. Treasury zero-coupon issues commensurate with the expected term. Management generally uses the simplified method to calculate the expected term for employee grants as the Company has limited historical exercise data or alternative information to reasonably estimate an expected term assumption. The simplified method assumes that all options will be exercised midway between the weighted average vesting date and the contractual term of the option. Stock-based compensation expense recognized in the Company’s consolidated financial statements is based on awards that are expected to vest. These expense amounts have been reduced by using an estimated forfeiture rate. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company evaluates the assumptions used to estimate forfeitures annually in connection with the recognition of stock-based compensation expense. Income (Loss) Per Share Basic income (loss) per share is calculated by dividing net income (loss) applicable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share is calculated by dividing the net loss attributable to common stockholders by the sum of the weighted average number of common shares outstanding plus potential dilutive common shares outstanding during the period. Potential dilutive securities, comprised of stock warrants, restricted stock units and stock options, are not reflected in diluted income (loss) per share because such shares are anti–dilutive. Dilutive impact of potential common shares resulting from common stock equivalents is determined by applying the treasury stock method. For the year ended March 31, 2022, there were 6,491,081 shares, consisting of 2,879,008 stock options, 954,775 restricted stock units and 2,657,298 stock warrants, that were not included in the computation of diluted loss per share because their effect would be anti-dilutive. For the three months ended March 31, 2021, there were 3,637,937 shares, consisting of 2,543,125 stock options, 935,397 restricted stock units and 159,415 stock warrants, that were not included in the computation of diluted loss per share because their effect would be anti-dilutive. For the year ended December 31, 2020, there were 3,285,058 shares, consisting of 2,320,318 stock options, 805,325 restricted stock units and 159,415 stock warrants, that were not included in the computation of diluted loss per share because their effect would be anti-dilutive. Fair Value Measurement Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The carrying values of the Company’s financial instruments such as cash equivalents, accounts receivable, revolving credit facility, accounts payable and accrued liabilities approximate fair values due to the short-term nature of these items. Income Taxes The Company accounts for income taxes in accordance with Accounting Standards Codification (“ASC”) 740, Income Taxes (“ASC 740”). ASC 740 prescribes the use of the liability method. Deferred tax assets and liabilities are determined based on the difference between the financial statement carrying amounts and the tax basis of assets and liabilities and are measured using the enacted statutory tax rates in effect at the balance sheet date. The Company records a valuation allowance to reduce its deferred tax assets when uncertainty regarding their realizability exists. Equity Method Investments The Company uses the equity method to account for investments in entities that it does not control, but in which it has the ability to exercise significant influence over operating and financial policies. The Company's proportionate share of the net income or loss of these companies is included in consolidated net loss. Judgments regarding the level of influence over each equity method investment include consideration of key factors such as the Company's ownership interest, representation on the board of directors or other management body and participation in policy-making decisions. Segment Reporting The Company’s operations and its financial performance is evaluated on a consolidated basis by the chief operating decision maker. The Company’s chief operating decision maker is the Parent’s Chief Executive Officer. Accordingly, the Company considers all of its operations to be aggregated in one reportable operating segment. For the year ended March 31, 2022, total revenue was $24.1 million, of which $23.4 million was from U.S. operations and $698 thousand was from Japan operations. For the three months ended March 31, 2021, total revenue was $2.4 million, of which $2.0 million was from U.S. operations and $449 thousand was from Japan operations. For the year ended December 31, 2020, total revenue was $11.4 million, of which $10.7 million was from U.S. operations and $713 thousand was from Japan operations. Recently Issued Accounting Standards under Evaluation Debt - In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, to address the complexity in accounting for certain financial instruments with characteristics of liabilities and equity. Amongst other provisions, the amendments in this ASU significantly change the guidance on the issuer’s accounting for convertible instruments and the guidance on the derivative scope exception for contracts in an entity’s own equity such that fewer conversion features will require separate recognition, and fewer freestanding instruments, like warrants, will require liability treatment. Refer to our white paper, Accounting simplifications for convertible instruments and warrants, for additional information. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements. Leases - In June 2020, the FASB issued ASU 2020-05, which amends the effective dates of the FASB’s standards on leasing (ASC 842) to give immediate relief to certain entities as a result of the widespread adverse economic effects and business disruptions caused by the COVID-19 pandemic. In February 2016, the FASB issued ASU 2016-02, Leases , which, for operating leases, requires the lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, on its balance sheet. The guidance also requires a lessee to recognize single lease costs, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. The leasing standard’s effective dates were the fiscal year beginning after December 15, 2019 as originally issued (ASU 2016-02) and the fiscal year beginning after December 15, 2020 as amended by ASU 2019-10. As amended by ASU 2020-05, the leasing standard’s effective date is now the fiscal year beginning after December 15, 2021. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements. Financial Instruments - FASB ASU 2020-03, Codification Improvements to Financial Instruments , makes clear the determination of the contractual life of a net investment in leases in estimating expected credit losses under ASC 326, Financial Instruments – Credit Losses. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). The standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. ASU 2016-13 is effective for the Company in 2023. Early adoption is permitted. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements. Income Tax - In December 2019, the FASB issued ASU 2019-12, which modifies ASC 740 to simplify the accounting for income taxes. The ASU’s amendments are based on changes that were suggested by stakeholders as part of the FASB’s simplification initiative (i.e., the FASB’s effort to reduce the complexity of accounting standards while maintaining or enhancing the helpfulness of information provided to financial statement users). ASU 2019-12 is effective for fiscal years beginning after December 15, 2022. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements. |

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Nexperia Arrangement | Nexperia Arrangement Nexperia Transaction On April 4, 2018, the Company entered into a multi-element commercial arrangement with Nexperia B.V. (“Nexperia”) to obtain financing in exchange for the sale of equity instruments and performing certain technology and product development activities for Nexperia (collectively, the “Collaboration Arrangement”). Nexperia specializes in designing, manufacturing and selling a broad range of small discrete semiconductor devices that utilize components such as those manufactured by the Company. Financing under the Collaboration Arrangement is comprised of the following elements: • $16 million Series 3 preferred stock issuance • $9 million license fee for transfer of the Gen-3 manufacturing process • $5 million development loan, originally maturing March 31, 2020 and subsequently extended to June 30, 2020 intended to pre-fund the Gen-4 (Tranche A) technology development (the “Tranche A Loan”) • $10 million development loan maturing March 31, 2021 intended to pre-fund the Gen-5 and 900V technology development (the “Tranche B Loan”) • $10 million revolving loan (the “Tranche C Loan”) By entering into this Collaboration Arrangement, Nexperia gained access to technology that allows for the production of high power semiconductors for use in electric vehicles. Further, Nexperia obtained an exclusive license and market access to automotive customers outside of Japan and a sole license (non-exclusive of the Company), as well as market access to customers in other parts of the power market. Nexperia has a lien on certain of the Company’s U.S. patents not relating to metal organic chemical vapor deposition (“MOCVD”) or epiwafer technology, per the agreement. On March 31, 2019, the Company executed Amendment No. 1 to the Loan and Security Agreement (the ”LSA”), pursuant to which the Tranche B Loan was bifurcated into the following two separate sub-tranches: • $8 million development loan intended to pre-fund the Gen-5 and 900V (Tranche B) technology development (the “Tranche B Loan”) • $2 million development loan intended to pre-fund the 1200V technology development (the “Tranche B-1 Loan” and, together with the Tranche B Loan, the “Tranche B Loans”) On February 7, 2020, Amendment No. 2 to the LSA was executed to acknowledge the then-pending Merger, reaffirm the terms of the loans and confirm the waiver for the late delivery of the Company’s 2018 audited financial statements. On April 8, 2020, Amendment No. 3 to the LSA was executed to extend the maturity of the Tranche A Loan to April 30, 2020. On April 28, 2020, Amendment No. 4 to the LSA was executed to further extend the maturity of the Tranche A Loan to June 30, 2020. All other terms set forth under the original LSA remained unchanged following the amendments. The Tranche A and Tranche B Loans represent pre-funding for Gen-4 (Tranche A), Gen-5 (Tranche B), and 900V (Tranche B-1) technology development for Nexperia. The specific development activities and associated performance milestones are contained within a Statement of Work (“SoW”) between the Company and Nexperia. The SoW may be modified from time to time based upon mutual business interests. This promise to perform the technology development is a good/service provided to a customer in exchange for consideration in the form of the technology development license fees that offset the Tranche A and Tranche B Loans outstanding. The Development Loans are recognized as a liability equal to the cash proceeds received. In relation to the license fee for the transfer of the Company’s Gen-3 manufacturing process to Nexperia, the Company received $3 million (the first of three tranches) in October 2018, $3 million (the second of three tranches) in April 2019, and $3 million (the third of three tranches) in October 2019. The Company recognized $9.0 million as perpetual licensing revenue during 2019 upon the completion of the transfer of the Company’s Gen-3 manufacturing process technology and mutual sign off between Nexperia and the Company. In January 2019, the Company received the $5 million Tranche A Loan. In June 2020, Nexperia agreed that the $5 million Tranche A Loan was permanently satisfied in full in connection with the Company transferring its Gen-4 technology development to Nexperia, at which point the Company recognized $5 million as perpetual licensing revenue. In June and July 2019, the Company received the $8 million Tranche B Loan. In December 2019, the Company received the $2 million Tranche B-1 Loan. The Company received the full $10 million Tranche C Loan under the credit facility during the year ended December 31, 2018. See Note 9 - Debts. On March 1, 2021, Amendment No. 5 to the LSA was executed to extend the maturity of the Tranche B loans of $10 million and the Tranche C Loan of $10 million to June 30, 2021 and May 18, 2021, respectively. On May 18, 2021, Amendment No. 6 to the LSA was executed to (1) extend the maturity date for the Tranche C Loans to the earlier of April 4, 2023 and the occurrence of specified change of control events, (2) add Parent as a guarantor of Transphorm Technology’s obligations under the Loan Agreement, and (3) convert the outstanding $2 million Tranche B-1 Loan into a Tranche C-1 Loan, which Tranche C-1 Loan has the same terms and conditions as the existing Tranche C Loan. On May 18, 2021, in addition to Amendment No. 6 to the LSA, the Company entered into a series of agreements with Nexperia, as described below. Strategic Cooperation Agreement The strategic cooperation agreement serves as a framework agreement that describes the numerous agreements between the parties and provides Nexperia with information rights and inspection rights with respect to the Company’s business. Option Agreement The option agreement establishes the parameters pursuant to which Nexperia, in certain limited instances, is permitted to exercise an option (the “Option”) to acquire Transphorm Japan Epi, Inc. (“TJE”), a Japanese subsidiary of the Company through which the Company is engaged in the development, manufacturing and sales of gallium nitride (“GaN”) based epitaxial wafer products. In general, the Option is exercisable upon (1) certain acquisitions of securities or assets of the Company or its subsidiaries by a Competitor (as defined in the option agreement) that results in the Company, directly or indirectly, owning less than a majority of TJE, which acquisition is followed by any material breach (that is not cured within a specified time period) by the Company or a subsidiary of its obligations with respect to epiwafer supply to Nexperia under the Company’s amended and restated supply agreement (the “Supply Agreement”) with Nexperia, or (2) the unilateral termination by the Company of the Supply Agreement. The option agreement also establishes the material terms, including price and timing, for the exercise of the Option by Nexperia. The Option terminates (1) if the Option is not exercised by Nexperia prior to the date on which the option agreement terminates, or (2) on the first to occur of (a) the termination of the option agreement upon written agreement of the parties, (b) the mutual termination or expiration of the Supply Agreement, or (c) the first to occur of (i) two years following the date on which the Company notifies Nexperia of epiwafer qualification of a second source and (ii) April 1, 2028. In connection with the option agreement, the Company has also amended and restated its existing intracompany license agreement with TJE to clarify Nexperia’s rights upon exercise of the Option. Amended and Restated Development and License Agreement The Company entered into an amended and restated development and license agreement (the “DLA”) with Nexperia, pursuant to which the Company agreed to develop and transfer to Nexperia certain manufacturing process technologies to enable Nexperia to manufacture GaN-based products at Nexperia’s facilities. These technologies to be transferred included the Company’s Gen-3, Gen-4 (Tranche A), and Gen-5 and 900V (Tranche B) process technologies, but do not include the Company’s Epi Process Technology (as defined in the DLA). Nexperia also agreed to provide funding for the development of such technologies in return for limited exclusivities in automotive and other fields. Nexperia’s rights now include sale of products in the automotive field in Japan along with Transphorm’s rights for sale of products in the automotive field in Japan which remain in place. As per the original agreement, after April 2023, Nexperia’s exclusive rights for sale of products in the automotive field outside of Japan terminate. In addition, the parties have clarified the ability of Nexperia’s customers to use products developed by Nexperia through exercise of its rights under this agreement. Amended and Restated Supply Agreement The Company entered into the Supply Agreement with Nexperia, which sets forth the terms under which Nexperia may purchase epiwafers and processed wafers from the Company, and the Company may purchase processed wafers from Nexperia. The agreement specifies that Nexperia is the Company’s priority customer with respect to epiwafers manufactured by TJE and, accordingly, has preferred utilization of extra capacity, and further specifies procedures to address expansion of the Company’s epiwafer manufacturing capacity and Nexperia’s obligations with respect thereto. The term of the Supply Agreement was extended until December 31, 2025, with automatic one year renewals thereafter, and the Company may not terminate the Supply Agreement while the Option Agreement is in effect. On June 30, 2021, Amendment No. 7 to the LSA was executed to extend the maturity of the Tranche B loans of $8 million to July 16, 2021. On July 16, 2021, Nexperia agreed that the $8 million Tranche B Loan was satisfied in full in connection with the Company transferring its Gen-5 and 900V technology developments to Nexperia, at which point the Company recognized $8 million as perpetual licensing revenue. |

Risks and Uncertainties [Abstract] | |
Concentration of Credit Risk and Significant Customers | Concentration of Credit Risk and Significant Customers The Company manages its credit risk associated with exposure to distributors and direct customers on outstanding accounts receivable through the application of credit approvals and other monitoring procedures. Credit sales, which are mainly on credit terms of 30 to 60 days, are only made to customers who meet the Company's credit standards, while sales to new customers or customers with low credit ratings are usually made on an advance payment basis. The Company closely monitors the aging of accounts receivable from its distributors and direct customers, and regularly reviews their financial positions, where available. Significant customers are those that represent 10% or more of revenue or accounts receivable. Total revenues, by percentage, from individual customers representing 10% or more of total revenues in the respective periods were as follows: For the Year Ended March 31, 2022 For the Three Month Transition Period Ended March 31, 2021 For the Year Ended December 31, 2020 Customer A 42.4% 27.3% 59.6% Customer B 16.1% 31.2% 29.2% Customer C 19.6% * * Customer D * * * * Less than 10% of total Accounts receivable, by percentage, from individual customers representing 10% or more of accounts receivable are set forth in the following table: As of March 31, 2022 2021 Customer A 20.1% 31.1% Customer B 19.4% 33.9% Customer C 38.8% * Customer D * 10.0% * Less than 10% of total Customer A is a related party and Customer B is a government agency.

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Investment in Joint Venture | Investment in Joint Venture Through July 31, 2021, the Company was party to a joint venture agreement (the “JVA”), by and among Aizu Fujitsu Semiconductor Limited, Fujitsu Semiconductor Limited (“FSL”), the Company and Transphorm Aizu, Inc. (“Transphorm Aizu”) for the ownership and operations of Aizu Fujitsu Semiconductor Wafer Solution Limited (“AFSW”). Through July 31, 2021, the Company held a 49% interest in AFSW through Transphorm Aizu, the Company’s wholly-owned subsidiary established in Japan to manage the financial transactions around AFSW. Transphorm Aizu and FSL funded AFSW based on a mutually agreed funding schedule. Any outstanding balances were reviewed upon the conclusion of the JVA effective July 31, 2021 to assess unfunded commitment to joint venture liability. During the year ended March 31, 2022, the Company recognized a $1.5 million gain, in other income, upon termination of the JVA and settlement of its obligation. On April 1, 2020, FSL exercised its put option under the JVA and notified the Company that FSL intended to exit the joint venture by selling its 51% interest in AFSW to the Company. In December 2020, the Company entered into a joint venture agreement with JCP Capital Management, LLC Limited (controlling party with 75% ownership) to create GaNovation, a joint venture company in Singapore, to engage in the business of distribution, development and supply of GaN products and, upon approval of the regulatory authorities in Japan, to purchase FSL’s and Transphorm’s interests in AFSW. In July 2021, regulatory authorities in Japan approved GaNovation’s purchase of 100% of the interests in AFSW from Transphorm and FSL. On July 20, 2021, Transphorm Aizu entered into a Share Purchase Agreement (the “Purchase Agreement”) with GaNovation, pursuant to which GaNovation agreed to acquire Transphorm’s 49% interest in AFSW from Transphorm Aizu for 1 Japanese Yen. The closing of the Purchase Agreement occurred on August 1, 2021. Following the closing of the Purchase Agreement and other concurrent transactions between GaNovation and FSL, GaNovation owns 100% of AFSW and Transphorm now holds a 25% interest in GaNovation. For the year ended March 31, 2022, GaNovation’s primary business activity related to the businesses of AFSW. The Company and JCP Capital Management, LLC Limited (“JCP”) have agreed to use their best efforts to maintain the operations of AFSW until at least August 1, 2022. GaNovation (through AFSW) manufactures semiconductor products exclusively for its owners under manufacturing agreements at prices estimated to cover the cost of production. GaNovation was determined to be a variable interest entity as the equity at risk was not believed to be sufficient. GaNovation depends on its owners for any additional cash. The Company extended $2.0 million and $2.5 million to GaNovation and AFSW to fund operations of GaNovation and AFSW, respectively, for the year ended March 31, 2022, and $968 thousand and $7.3 million to AFSW to fund AFSW’s operations for the three months ended March 31, 2021 and the year ended December 31, 2020, respectively. The Company’s known maximum exposure to loss approximated the carrying value of its investment balance, which included the financing. Potential future losses could be higher than the carrying amount of the Company’s investment, as the Company is liable for other future operating costs or obligations of GaNovation. In addition, because Transphorm is currently committed to purchasing GaN wafers and production-related services from AFSW at pre-agreed pricing based upon the Company’s second generation products, the Company may be required to purchase products at a higher cost for its newer generation products. Investment in GaNovation was $143 thousand as of March 31, 2022, and unfunded commitment to GaNovation was $1.9 million and $1.5 million as of March 31, 2021 and December 31, 2020, respectively. JCP is responsible for 75% of the funding obligations and losses of AFSW, while Transphorm is responsible for 25% of the funding obligations and losses of AFSW for the period from April 1, 2022 through March 31, 2023 and JCP is responsible for 67.5% of the funding obligations and losses of AFSW, while Transphorm is responsible for 32.5% of the funding obligations and losses of AFSW for the period from April 1, 2023 and thereafter, except that JCP’s total funding obligations or investments shall not exceed $35 million and Transphorm’s total funding obligations or investment shall not exceed $12 million for the three The Company’s investment activities in GaNovation and AFSW for the periods presented are summarized below (in thousands) : AFSW (Joint Venture Between the Company and FSL) January 1, 2020 $ (1,688) Investment 7,348 Loss (6,836) Effect of exchange rate change (290) December 31, 2020 (1,466) Investment 968 Loss (1,468) Effect of exchange rate change 100 March 31, 2021 (1,866) Investment 2,490 Loss (2,078) Gain 1,455 Effect of exchange rate change (1) July 31, 2021 $ — GaNovation (Joint Venture Between the Company and JCP) August 1, 2021 $ — Investment 2,036 Loss (1,893) Effect of exchange rate change — March 31, 2022 $ 143 Summarized unaudited financial information of GaNovation and AFSW for the periods indicated are as follows (in thousands) : GaNovation AFSW March 31, 2022 March 31, 2021 Current assets 4,259 $ 932 Long-term assets 3,690 $ 5,330 Other current liabilities 3,799 $ 2,200 Due to controlling owner (1) $ 22,354 Due to Transphorm — $ 13,179 Net surplus (deficit) 4,151 $ (31,471) GaNovation AFSW For the Eight Months Ended March 31, 2022 For the Four Months Ended July 31, 2021 For the Three Month Transition Period Ended March 31, 2021 For the Year Ended December 31, 2020 Sales $ 6,933 $ 2,176 $ 842 $ 2,976 Gross loss $ (6,168) $ (3,191) $ (2,425) $ (11,411) Net loss $ (7,707) $ (4,260) $ (2,995) $ (13,952) |

See Note 3 - Nexperia Arrangement. The Tranche C Loans are recorded based on principal in the amount of $12.0 million and accrued interest (6% interest per annum). The Company recorded interest expense of $715 thousand for the year ended March 31, 2022, $150 thousand for the three months ended March 31, 2021 and $610 thousand for the year ended December 31, 2020.

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Commitment with a Government Agency In connection with a contract with a government agency, the Company entered into a commitment to acquire equipment and services from vendors totaling $7.4 million, all of which is reimbursable. The contract’s expiration date was March and June 2022 but such dates were subsequently extended to June and December 2022, respectively. The Company has made total purchases of $7.3 million cumulatively as of March 31, 2022, of which $7.2 million was reimbursed by the government agency as of March 31, 2022. During the year ended March 31, 2022, the Company made purchases of $369 thousand and the remaining accounts payable to the vendors was $131 thousand as of March 31, 2022. In September 2021, the Company was awarded a $0.9 million contract with a $0.5 million option by a government agency for delivering epiwafer technology. The Company billed and received $211 thousand for the year ended March 31, 2022. Operating Leases The Company leases office and fabrication space in Goleta, California, and office space in Campbell, California and in Japan, China, Hong Kong, Taiwan and the Philippines under noncancelable operating lease agreements. The terms of certain leases provide for escalating rental payments through the term of the lease. The Company recognizes rent expense on a straight-line basis over the lease term and accrues for rent expense incurred but not paid. As of March 31, 2022, future minimum operating lease commitments were as follows (in thousands) : Year Ending March 31, 2023 $ 681 2024 647 2025 156 Total $ 1,484 The Company recorded rent expense, net of rental income, which includes common area maintenance fees in addition to the base rent, of $918 thousand for the year ended March 31, 2022, $212 thousand for the three months ended March 31, 2021 and $892 thousand for the year ended December 31, 2020. Rental income from a noncancelable sublease was $0 for the year ended March 31, 2022, $30 thousand for the three months ended March 31, 2021 and $182 thousand for the year ended December 31, 2020. As of March 31, 2022, there are no future minimum rental payments to be received under the noncancelable sublease. Contingencies During the ordinary course of business, the Company may become a party to legal proceedings incidental to its business. The Company accrues contingent liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. Legal cost is expensed as incurred. On April 5, 2022, Joel Newman, an alleged holder of the Company’s common stock, filed a complaint in the Delaware Court of Chancery derivatively against the Company’s directors and KKR Phorm Investors L.P. (“Phorm”). The complaint alleges that the directors and Phorm breached their fiduciary duties, and the directors committed waste, because the terms of the November 5, 2021 private placement in which Phorm participated were unfairly favorable to Phorm. The directors have the right to advancement from the Company of expenses incurred defending the claims. The defendants filed motions to dismiss on May 26, 2022. The Company is unable to estimate the potential loss or range of loss, if any, associated with this lawsuit. The Company is not aware of any material legal claims or assessments other than disclosed above. Although the results of litigation and claims are inherently unpredictable, management believes there was not at least a reasonable possibility that the Company had incurred a material loss with respect to any loss contingencies as of March 31, 2022 and through the issuance of these financial statements. Indemnification The Company from time to time enters into types of contracts that contingently require the Company to indemnify parties against third-party claims. These contracts primarily relate to: (1) real estate leases, under which the Company may be required to indemnify property owners for environmental and other liabilities and for other claims arising from the Company’s use of the applicable premises; (2) agreements with the Company’s officers, directors, and employees, under which the Company may be required to indemnify such persons from liabilities arising out of their relationship; (3) indemnifying customers in the event of product failure; and (4) agreements with outside parties that use the Company’s intellectual property, under which the Company may indemnify for copyright or patent infringement related specifically to the use of such intellectual property. Historically, the Company has not been required to make payments under these obligations, and no liabilities have been recorded for these obligations in the Company’s consolidated financial statements. |

The exercise price of the warrants is not subject to “price-based” anti-dilution adjustment.

Our stockholders approved the 2020 Plan on February 11, 2020. We assumed the 2020 Plan in connection with the Merger. The 2020 Plan provides for the grant of incentive stock options, within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), to our employees and our parent and subsidiary corporations’ employees, and for the grant of nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance units, and performance shares to our employees, directors, and consultants and our parent and subsidiary corporations’ employees and consultants. As of March 31, 2022, there were 2,879,008 stock options outstanding, 954,775 restricted stock units outstanding and 2,874,060 shares available for grant under the 2020 Plan. During the year ended March 31, 2022, 2,026,599 shares were added to the 2020 Plan pursuant to an automatic annual increase provision in the plan. Subject to the adjustment provisions of the 2020 Plan, and the automatic increase described in the 2020 Plan, the maximum aggregate number of shares of our common stock that may be issued under the 2020 Plan is 5,050,000 shares of our common stock, which includes (i) 2,588,077 shares initially reserved for issuance, plus (ii) any shares of our common stock subject to issued and outstanding awards under the 2007 Plan or 2015 Plan that were assumed in the Merger and that, on or after the closing of the Merger, expire or otherwise terminate without having been exercised or issued in full, are tendered to or withheld by us for payment of an exercise price or for tax withholding obligations, or are forfeited to or repurchased by us due to failure to vest, with the maximum number of shares to be added to the 2020 Plan pursuant to this clause (ii) equal to 2,461,923 shares. Subject to the adjustment provisions of the 2020 Plan, the number of shares of common stock available for issuance under the 2020 Plan will also include an annual increase on the first day of each fiscal year beginning with our 2022 fiscal year and ending on (and including) our 2030 fiscal year, in an amount equal to the least of: 5,000,000 shares of our common stock; five percent (5%) of the outstanding shares of our common stock on the last day of the immediately preceding fiscal year; or such number of shares of our common stock as the administrator of the 2020 Plan may determine. Stock Options The following table summarizes stock option activity and related information for the periods presented: Number of Options Weighted Average Exercise Price per Share Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Outstanding at January 1, 2020 2,473,198 $ 4.67 6.84 $ — Options granted — $ — Options exercised (6,821) $ 3.78 Options canceled (146,059) $ 5.88 Outstanding at December 31, 2020 2,320,318 $ 4.67 5.92 $ — Exercisable at December 31, 2020 2,267,154 $ 4.70 5.86 $ — Outstanding at January 1, 2021 2,320,318 $ 4.67 5.92 $ — Options granted 223,638 $ 6.37 Options exercised (500) $ 3.14 Options canceled (331) $ 9.29 Outstanding at March 31, 2021 2,543,125 $ 4.82 6.05 $ — Exercisable at March 31, 2021 2,283,243 $ 4.70 5.65 $ — Outstanding at April 1, 2021 2,543,125 $ 4.82 6.05 $ — Options granted 528,077 $ 6.31 Options exercised (52,799) $ 4.19 Options canceled (139,395) $ 9.52 Outstanding at March 31, 2022 2,879,008 $ 4.88 6.02 $ 6,747 Exercisable at March 31, 2022 2,206,259 $ 4.44 4.99 $ 5,984 (1) Intrinsic value represents the excess of the fair value on the last day of the period (which was $7.07, $3.75 and $3.01 as of March 31, 2022, March 31, 2021 and December 31, 2020, respectively) over the exercise price, multiplied by the number of options. Stock-based compensation expense is determined based on the fair value of the Company’s common stock as determined by the Board of Directors and assumptions such as volatility, expected term, risk-free interest rates, and other factors. Changes in the deemed fair value of the common stock, the underlying assumptions in the calculations, the number of options granted or the terms of such options, the expected forfeiture rate, the treatment of tax benefits and other changes may result in significant differences in the amounts or timing of the compensation expense recognized. The assumptions and estimates are made as follows: • Expected Volatility - The Company utilizes the historical volatility of representative public companies to determine its expected volatility, as the trading history of the Company’s common stock is limited. • Estimated Forfeitures - The Company adopted ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting and has elected to account for forfeitures as they occur and therefore, stock-based compensation expense has been calculated based on actual forfeitures in the statements of operations, rather than our previous approach which was net of estimated forfeitures. The net cumulative effect of this change was not material. • Expected Dividend Yield - The Company has not issued any common stock dividends; therefore, a dividend yield of zero was used. • Risk-Free Interest Rate - The Company bases the risk-free interest rate used in the Black-Scholes-Merton option pricing model on the implied yield currently available on United States Treasury zero-coupon issues with an equivalent expected term. • Expected Term - The expected term of stock options represents the period that the Company’s stock options are expected to be outstanding. The Company generally uses the simplified method to calculate the expected term for employee grants. The assumptions used to value options granted to employees during the periods presented was as follows: Year Ended March 31, 2022 Three Month Transition Period Ended March 31, 2021 Weighted average expected life (in years) 5.87 5.23 Risk-free interest rate 1.08% - 1.32% 0.78% - 1.73% Expected volatility 42.5% - 43.8% 43.1% - 44.3% Grant date fair market value $6.34 $3.75 Grant date fair value $1.94 - $3.32 $0.94 - $1.65 Dividend yield —% —% Restricted Stock Restricted Stock Awards RSAs are grants of shares of our common stock that vest in accordance with terms and conditions established by the Company’s Board of Directors. Recipients of RSAs generally will have voting and dividend rights with respect to such shares upon grant without regard to vesting, unless the RSA agreement provides otherwise. Shares of restricted stock that do not vest are subject to forfeiture. In September 2020, we granted 123,501 RSAs outside of our 2020 Plan, 98,450 of which were fully vested on the date of grant and the remainder of which vested in January 2021. In December 2020, we granted 12,000 RSAs outside of our 2020 Plan, all of which were fully vested on the date of grant. There were no RSAs outstanding as of March 31, 2021 and no RSA activities during the year ended March 31, 2022. The following table summarizes RSA activity and related information for the periods presented: Number of Shares Weighted-Average Grant Date Fair Value Per Share January 1, 2020 — $ — Granted 135,501 $ 3.91 Vested (98,450) $ 3.88 December 31, 2020 37,051 $ 4.00 Granted — $ — Vested (37,051) $ 4.00 March 31, 2021 — $ — Granted — $ — Vested — $ — March 31, 2022 — $ — Restricted Stock Units RSUs are grants of shares of our common stock that vest in accordance with terms and conditions established by the administrator of the 2020 Plan.

We granted 816,180 RSUs during the three months ended September 30, 2020, 4,000 of which were fully vested on the date of grant. The remainder of the RSUs are scheduled to vest as follows: one third will vest on each of January 1, 2022, January 1, 2023 and July 1, 2023, in each case subject to the RSU holders’ continued status as a service provider to the Company through each vesting date. We granted 137,452 RSUs during the three months ended March 31, 2021, which are scheduled to vest in various periods, beginning immediately and ending on February 2025, in each case subject to the RSU holders’ continued status as a service provider to the Company through each vesting date. We granted 35,000 RSUs during the three months ended September 30, 2021, 25 percent of which are scheduled to vest after one year and the remainder are scheduled to vest each quarter for three years, in each case subject to the RSU holders’ continued status as a service provider to the Company through each vesting date. We granted 307,640 RSUs during the three months ended December 31, 2021, 25% of which are scheduled to vest annually over four years on each anniversary of the vesting commencement date, in each case subject to the RSU holders’ continued status as a service provider to the Company through the applicable vesting date.

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Fair Value Measurements FASB ASC 820, Fair Value Measurements and Disclosures , establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows: Level 1 - Unadjusted quoted prices in active markets for identical assets and liabilities. Level 2 - Inputs (other than quoted prices included within Level 1) that are observable, unadjusted quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data of substantially the full term of the related assets or liabilities. Level 3 - Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Inputs are unobservable for the asset or liability. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following table summarizes the Company’s liabilities measured at fair value as of the dates presented, by level within the fair value hierarchy (in thousands) : Level 1 Level 2 Level 3 March 31, 2022 Promissory note $ — $ — $ — March 31, 2021 Promissory note $ — $ — $ 16,128 The following table includes the changes in fair value of the promissory note which are Level 3 on the fair value hierarchy (in thousands) : January 1, 2020 $ 16,169 Interest expense accrued 150 Decrease in fair value (927) December 31, 2020 15,392 Interest expense accrued 37 Increase in fair value 699 March 31, 2021 16,128 Interest expense accrued 77 Decrease in fair value (605) Conversion (15,600) March 31, 2022 $ — On October 4, 2021, the promissory note of $15.6 million, consisting of an outstanding principal amount of $15.0 million plus accrued but unpaid interest of $600 thousand, was converted into an aggregate of 3,120,000 shares of common stock. See Note 9 - Debts and Note 11 - Stockholders’ Equity (Deficit). The Company recorded interest expense of $77 thousand for the year ended March 31, 2022, $37 thousand for the three months ended March 31, 2021 and $150 thousand for the year ended December 31, 2020. Fair value of promissory note decreased by $605 thousand for the year ended March 31, 2022, increased $699 thousand for the three months ended March 31, 2021 and decreased $927 thousand for the year ended December 31, 2020. Level 3 borrowings, which consist of promissory note, are measured and reported at fair value using a Monte Carlo simulation valuation model. The models can include assumptions related to the value of the notes that are based on the estimated timing and amounts of future rounds of financing, including the estimated timing of a change in control of the Company, and estimated market interest rates, which represent significant unobservable inputs. Assumptions used are (1) the Company is worth today what it can generate in future cash to the Company, (2) cash received today is more than an equal amount of cash received in the future, and (3) future cash flows can be reasonably estimated. The following table summarizes assumptions used for fair value of promissory note as of the dates presented: March 31, 2021 Stock price $3.75 Time 1.5 years Risk-free rate 0.12% Volatility 50.6% |

Income Tax Disclosure [Abstract] | |
Income Taxes | Income Taxes For the year ended March 31, 2022, the Company reported a worldwide consolidated pre-tax loss of $10.2 million, which consisted of a pre-tax loss from U.S. operations of approximately $8.8 million and pre-tax loss from Japan operations of approximately $1.4 million. The pre-tax loss from Japan operations consists of $1.2 million from Transphorm Japan, Inc., $627 thousand pre-tax loss from Transphorm Aizu, Inc. and $344 thousand pre-tax income from Transphorm Japan Epi, Inc. For the three months ended March 31, 2021, the Company reported a worldwide consolidated pretax loss of $6.6 million, which consisted of a pre-tax loss from U.S. operations of approximately $4.9 million and pre-tax loss from Japan operations of approximately $1.7 million. The pre-tax loss from Japan operations primarily consists of $1.5 million from Transphorm Aizu, Inc. with nominal pre-tax book loss from Transphorm Japan, Inc. and Transphorm Japan Epi, Inc. For the year ended December 31, 2020, the Company reported a worldwide consolidated pretax loss of $17.9 million, which consisted of a pre-tax loss from U.S. operations of approximately $10.3 million and pre-tax loss from Japan operations of approximately $7.6 million. The pre-tax loss from Japan operations consists of $800 thousand from Transphorm Japan, Inc., $6.8 million pre-tax loss from Transphorm Aizu, Inc. and $25 thousand pre-tax income from Transphorm Japan Epi, Inc. There is no U.S. federal or foreign provision for income taxes because the Company has incurred operating losses since inception and is in a full valuation allowance position. For the year ended March 31, 2022, the three months ended March 31, 2021, and the year ended December 31, 2020, the Company recorded a state income tax provision of $1 thousand which represents minimum taxes. Deferred income taxes reflect the net tax effects of the net operating losses and the temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and deferred tax liabilities as of the dates presented as follows (in thousands) : March 31, 2022 March 31, 2021 Deferred tax assets: Net operating loss carryforwards $ 49,715 $ 47,424 Tax credits 6,171 5,444 California capitalized research and development 40 72 Others, net 564 581 Total deferred tax assets 56,490 53,521 Valuation allowance (56,550) (53,481) Deferred tax asset, net of valuation allowance (60) 40 Deferred tax liabilities: Fixed assets 60 (40) Total deferred tax liabilities 60 (40) Net deferred tax assets $ — $ — As of March 31, 2022 and March 31, 2021, the Company had no assurance that future taxable income would be sufficient to fully utilize the net operating loss carryforwards and other deferred tax assets in the future. Consequently, the Company determined that a valuation allowance of approximately $56.6 million and $53.5 million as of March 31, 2022 and March 31, 2021, respectively, was needed to offset the deferred tax assets resulting mainly from the net operating loss carryforwards. The Company files income tax returns in the U.S. federal, California, and Oregon jurisdictions and is subject to U.S. federal, state, and local income tax examinations by tax authorities. Generally, the statute of limitations is 3 years for U.S. federal income tax and 4 years for state and local taxes. The statute of limitations may be extended for tax years where a corporation has a net operating loss carryforward or by agreement with the jurisdictional taxing authority. Accordingly, all of the Company's U.S. federal, state and local income tax years since inception remain open to examination by tax authorities. The Company is not currently under audit by any taxing authority. The Company follows the provisions of uncertain tax positions as addressed in ASC 740-10. The Company recognized no increase or decrease in the liability for unrecognized tax benefits for any period presented. The Company recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in operating expenses. No such interest or penalties were recognized during the period presented. The Company had no accruals for interest and penalties at March 31, 2022 and March 31, 2021. The utilization of the Company’s net operating loss and tax credit carryforwards is dependent on the future profitability of the Company. Further, the Internal Revenue Code imposes substantial restrictions on the utilization of such carryforwards in the event of an ownership change of more than 50%, as defined, during any three-year period (Section 382 and 383 limitations). The Company has determined that several ownership changes have occurred, which have resulted in substantial limitations on the Company’s ability to utilize its pre-ownership change net operating loss and tax credit carryforwards. These substantial limitations are expected to result in both a permanent loss of certain tax benefits related to net operating loss carryforwards and federal research and development credits, as well as an annual utilization limitation. As of March 31, 2022, the Company performed an analysis for amounts that could be subject to Section 382 and 383 limitations and management did not believe such limitations existed. However, it is important to note that the Company continues to raise capital and such transaction could have an effect of such limitations. See Note 17 - Subsequent Events. The federal net operating loss generated for the year ended March 31, 2022 of $9.8 million, for the three months ended March 31, 2021 of $4.5 million and for the year ended December 31, 2020 of $10.5 million can be carried forward indefinitely. However, the federal deduction for net operating losses incurred in tax years beginning after January 1, 2021 is limited to 80% annual taxable income. Under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), the suspension of net operating losses generated in years 2018, 2019, 2020 and 2021 are not subject to the 80% limitation. The state net operating loss generated for the year ended March 31, 2022 of $2.6 million, for the three months ended March 31, 2021 of $1.0 million, and for the year ended December 31, 2020 of $2.6 million can be carried forward 20 years. As of March 31, 2022, the Company has federal net operating loss carryforwards of $258.9 million, of which $207.5 million will begin to expire in 2027 unless previously utilized, and the Company has state net operating loss carryforwards of $154.0 million which will begin to expire in 2028 unless previously utilized. The Company also has foreign net operating loss carryforwards of approximately $6.5 million which will begin to expire in 2024. As of March 31, 2022, the Company has federal research and development credit carryforwards of $5.0 million, which will begin to expire in 2032 unless previously utilized, and the Company had California research and development credit carryforwards of $4.3 million, which do not expire. Deferred tax assets have not been established for net operating and tax credit carryforwards that are deemed to have no value due to the Section 382 and 383 limitations discussed above and, therefore, are not reflected in the table of deferred tax assets presented above. Future ownership changes, if any, may further limit the Company’s ability to utilize its remaining net operating losses and tax credit carryforwards. The Company performed an analysis as of March 31, 2022 and it was determined that no further limitations on tax attributes were required. Reconciliation between federal statutory tax rate and the effective tax rate is shown in the following table for the periods presented: Year Ended March 31, 2022 Three Month Transition Period Ended March 31, 2021 Year Ended December 31, 2020 Federal statutory income tax rate 21.00 % 21.00 % 21.00 % Research and development credit 7.10 % 2.73 % 4.06 % Nondeductible expense 1.80 % (2.43) % 0.64 % Loss in joint venture (1.87) % (6.76) % (11.70) % Foreign income tax rate difference 1.39 % 2.45 % 4.10 % Others, net (0.40) % 0.85 % (2.08) % Valuation allowance (29.02) % (17.84) % (16.02) % Effective tax rate — % — % — % On March 27, 2020, the CARES Act was signed into law. The CARES Act repealed the 80% taxable income limitation for the 2018–2020 taxable years and reinstated NOL carrybacks for the 2018–2020 taxable years. In addition, the CARES Act temporarily increases the business interest deduction limitations from 30% to 50% of adjusted taxable income for the 2019 and 2020 taxable year. Lastly, a TCJA technical correction that classifies qualified improvement property as 15-year recovery period, allowing the bonus depreciation deduction to be claimed for such property retroactive as if it was included in the TCJA at the time of enactment. On December 21, 2020, the Consolidated Appropriations Act (“CAA”) was signed into law. We do not expect any of the enactments of the CAA to have a material impact on the Company as of March 31, 2022. |

Accounting Policies [Abstract] | |
Principles of Consolidation | The consolidated financial statements include the accounts of the Parent and its wholly-owned subsidiaries, Transphorm Technology, Transphorm Japan, Inc., Transphorm Japan Epi, Inc. and Transphorm Aizu, Inc. Upon consolidation, all significant intercompany accounts and transactions have been eliminated. |
Use of Estimates | The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Management bases its estimates and assumptions on historical experience, knowledge of current conditions, and its belief of what could occur in the future, given available information. Actual results could differ from those estimates, and such differences could be material to the consolidated financial statements. Estimates are used for, but not limited to, the determinations of fair value of stock awards and promissory notes, accrual of expenses, revenue recognition, allowance for doubtful accounts, inventory reserve, and useful lives for property and equipment. |
Cash, Cash Equivalents and Restricted Cash | The Company considers all highly-liquid investments with original maturities of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents consist principally of bank deposits and money market funds. |
Foreign Currency Risk | The Company is exposed to foreign currency risk due to its operations in Japan (Yen). Assets and liabilities of the operations are re-measured into U.S. currency at exchange rates in effect at the balance sheet dates through the consolidated statements of comprehensive income. Gains or losses resulting from foreign currency transactions are re-measured using the rates on the dates on which those elements are recognized during the period and are included in other income or expense in the consolidated statements of operations. |
Concentrations of Risk | Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents. The Company is exposed to credit risk in the event of default by the financial institution holding its cash. The Company’s investment policy restricts investments to high-quality investments and limits the amounts invested with any one issuer, industry or geographic area. Risks associated with cash holdings in excess of insured limits are mitigated by banking with high-quality institutions. To date, the Company has not experienced any significant losses on its cash and cash equivalents. The Company periodically evaluates the relative credit standing of these financial institutions. The Company is subject to risks common in the power conversion components industry, including, but not limited to, technological obsolescence, dependence on key personnel, market acceptance of its products, the successful protection of its proprietary technologies, compliance with government regulations, and the possibility of not being able to obtain additional financing when needed. |
Comprehensive Loss | Comprehensive loss is comprised of net loss and other comprehensive loss. Other comprehensive loss includes the impact of foreign currency translation adjustments. |
Accounts Receivable | Accounts receivable are analyzed and allowances for uncollectible accounts are recorded, as required. Provisions for uncollectible accounts, if any, are recorded as bad debt expense and included in general and administrative expenses in the accompanying consolidated statements of operations. The process for determining the appropriate level of allowances for doubtful accounts involves judgment, and the Company considers such factors as the age of the underlying receivables, historical and projected collection trends, the composition of outstanding receivables, current economic conditions and regulatory changes. An account is fully reserved when reasonable collection efforts have been unsuccessful and it is probable that the receivable will not be recovered. |
Inventory | Inventory is stated at the lower of cost (first-in, first-out method) or net realizable value. The Company periodically reviews the value of items in inventory and records write-downs or write-offs based on its assessment of slow moving or obsolete inventory. The Company maintains an inventory reserve for obsolete inventory and generally makes inventory value adjustments against the inventory reserve. |
Property and Equipment | Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is determined using the straight-line method over the estimated useful lives of the respective assets, generally ranging from three |
Property and Equipment, Impairment | The Company evaluates the carrying amount of its property and equipment whenever events or changes in circumstances indicate that the assets may not be recoverable. An impairment loss would be recognized when estimated future cash flows expected to result from the use of an asset or asset group and its eventual disposition are less than the carrying amount of the asset or asset group. |
Goodwill | Goodwill arose for the acquisition of a business in February 2014 based in Japan and was accounted for as the purchase of a business. Goodwill generated from business combinations and deemed to have indefinite lives are not subject to amortization and instead are tested for impairment at least annually in December unless certain events occur or circumstances change. Goodwill represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. We test for goodwill impairment annually, on March 31, or earlier if events or changes in circumstances indicate goodwill might possibly be impaired. Impairment exists when the carrying value of the goodwill exceeds its implied fair value. An impairment loss would be recognized in an amount equal to that excess as a charge to operations in the consolidated statements of operations. |
Intangible Assets | Intangible assets that are not considered to have an indefinite useful life are amortized over their estimated useful lives, which generally range from three |
Revenue Recognition | The Company derives its revenues from sales of high-powered GaN-based products manufactured utilizing the Company’s proprietary and patented epiwafer technology and wafer fabrication and other assembly processes, sales of GaN epiwafers for the radio frequency (“RF”) and power markets, and sales of licenses to use such patented proprietary technology, as well as enabling EPI wafer growth services and products to our strategic partners. Revenues are recognized when control of these products or licenses are transferred to the Company’s customers in an amount that reflects the consideration it expects to be entitled to in exchange for those products and licenses. Sales and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense. The Company does not have any significant financing components associated with its revenue contracts, as payment is received at or shortly after the point of sale. Disaggregation of Revenue from Contracts with Customers Revenue consists of perpetual licensing revenue, government contract revenue from our contract with the U.S. Navy and product sales, with applicable performance obligations satisfied at a point in time. Products are sold to distributors and end-users in various sectors such as, but not limited to, the automotive, gaming, industrial, IT, and consumer products industries. As part of the multi-element commercial arrangement executed with Nexperia on April 4, 2018 (see Note 3 - Nexperia Arrangement), the Company agreed to grant Nexperia the perpetual exclusive right to use the Company’s existing Gen-3 manufacturing process technology. License fees are received upon satisfaction of contractual milestones and recognized upon delivery of the perpetual license or transferred technology without any remaining performance obligations. The Company recognized $8.0 million of perpetual licensing revenue for the year ended March 31, 2022. No perpetual licensing revenue was recognized for the three months ended March 31, 2021. The Company recognized $5.0 million of perpetual licensing revenue for the year ended December 31, 2020. In December 2020, the Company entered into a cooperation and development agreement with Yaskawa Electric Corporation (“Yaskawa”), pursuant to which Yaskawa agreed to provide $4.0 million over approximately three years to fund development activities related to industrial power conversion applications, with an initial focus on servo motor drive applications. Yaskawa provided payments of $1.0 million and $750 thousand of this $4.0 million commitment in December 2020 and July 2021, respectively. The Company evaluated and concluded that the deliverables are the same and nature of the services to be provided to Yaskawa will be consistent over the period of approximately three years. Accordingly, with respect to the $1.8 million payment, the Company recognized $1.1 million as revenue for the year ended March 31, 2022, $333 thousand as revenue for the three months ended March 31, 2021 and $333 thousand as revenue for the year ended December 31, 2020. The Company also recorded $375 thousand as revenue for services rendered but not billed for the year ended March 31, 2022. Government contract revenues are principally generated under research and development contracts. Contract revenues are derived primarily from research contracts with agencies of the U.S. government. We believe credit risk related to accounts receivable arising from such contracts is minimal. These contracts may include cost-plus fixed fee and fixed price terms. All payments to us for work performed on contracts with agencies of the U.S. government are subject to adjustment upon audit by the Defense Contract Audit Agency. The contract’s expiration dates were initially March and June 2022, but such dates were subsequently extended to June and December 2022, respectively. The Company received new government authorized rates for billing purposes which allowed for retroactive application since inception. The cumulative impact of this rate change as of March 31, 2022 was $423 thousand, of which $(83) thousand and $505 thousand were recorded in the three months ended March 31, 2021 and year ended December 31, 2021, respectively. On February 1, 2022, the Company received new government authorized rates which allowed for retroactive application effective for the year ended December 31, 2020. The Company will use the new approved rates on a go-forward basis. Performance Obligations For performance obligations related to the sale of products, control transfers to the customer at a point in time. The Company’s principal terms of sale are free on board shipping or destination and the Company transfers control and records revenue for product sales upon shipment or delivery to the customer, respectively. For performance obligations related to the licensing of patented technology in perpetuity, control also transfers to the customer at a point in time. The Company transfers control and records revenue for licensing fees once the Company has (i) provided or otherwise makes available the patented technology to the customer and (ii) the customer is able to use and benefit from the patented technology. Variable Consideration The nature of the Company’s arrangement with Nexperia gives rise to variable consideration in the form of milestone and royalty payments. The royalties qualify for the sales and usage-based royalty exception, as the license of intellectual property is the predominant item to which the royalty relates and are recognized upon the subsequent sale occurring. The variable amounts are received upon satisfaction of contractually agreed upon development targets and sales volume. |
Research and Development | The Company is a party to research grant contracts with the U.S. government for which the Company is reimbursed for specified costs incurred for its research projects. These projects include energy saving initiatives for which the U.S. government offers reimbursement funds. Such reimbursements are recorded as an offset to research and development expenses when the related qualified research and development expenses are incurred. Reimbursable costs are recognized in the same period the costs are incurred up to the limit of approved funding amounts on qualified expenses. |
Stock-Based Compensation | All share-based payments, including grants of stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”), are measured at the fair value of the share-based awards on the grant date and recognized over their respective vesting periods, which is generally one The Black-Scholes-Merton option pricing model requires inputs such as the fair value of common stock on date of grant, expected term, expected volatility, dividend yield, and risk-free interest rate. Further, the forfeiture rate also affects the amount of aggregate compensation expense. These inputs are subjective and generally require significant analysis and judgment to develop. Volatility data is obtained from a study of publicly traded industry peer companies. The forfeiture rate is derived primarily from the Company’s historical data, and the risk-free interest rate is based on the yield available on U.S. Treasury zero-coupon issues commensurate with the expected term. Management generally uses the simplified method to calculate the expected term for employee grants as the Company has limited historical exercise data or alternative information to reasonably estimate an expected term assumption. The simplified method assumes that all options will be exercised midway between the weighted average vesting date and the contractual term of the option. Stock-based compensation expense recognized in the Company’s consolidated financial statements is based on awards that are expected to vest. These expense amounts have been reduced by using an estimated forfeiture rate. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company evaluates the assumptions used to estimate forfeitures annually in connection with the recognition of stock-based compensation expense. Stock-based compensation expense is determined based on the fair value of the Company’s common stock as determined by the Board of Directors and assumptions such as volatility, expected term, risk-free interest rates, and other factors. Changes in the deemed fair value of the common stock, the underlying assumptions in the calculations, the number of options granted or the terms of such options, the expected forfeiture rate, the treatment of tax benefits and other changes may result in significant differences in the amounts or timing of the compensation expense recognized. The assumptions and estimates are made as follows: • Expected Volatility - The Company utilizes the historical volatility of representative public companies to determine its expected volatility, as the trading history of the Company’s common stock is limited. • Estimated Forfeitures - The Company adopted ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting and has elected to account for forfeitures as they occur and therefore, stock-based compensation expense has been calculated based on actual forfeitures in the statements of operations, rather than our previous approach which was net of estimated forfeitures. The net cumulative effect of this change was not material. • Expected Dividend Yield - The Company has not issued any common stock dividends; therefore, a dividend yield of zero was used. • Risk-Free Interest Rate - The Company bases the risk-free interest rate used in the Black-Scholes-Merton option pricing model on the implied yield currently available on United States Treasury zero-coupon issues with an equivalent expected term. • Expected Term - The expected term of stock options represents the period that the Company’s stock options are expected to be outstanding. The Company generally uses the simplified method to calculate the expected term for employee grants. |
Income (Loss) Per Share | Basic income (loss) per share is calculated by dividing net income (loss) applicable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share is calculated by dividing the net loss attributable to common stockholders by the sum of the weighted average number of common shares outstanding plus potential dilutive common shares outstanding during the period. Potential dilutive securities, comprised of stock warrants, restricted stock units and stock options, are not reflected in diluted income (loss) per share because such shares are anti–dilutive. Dilutive impact of potential common shares resulting from common stock equivalents is determined by applying the treasury stock method. |
Fair Value Measurement | Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The carrying values of the Company’s financial instruments such as cash equivalents, accounts receivable, revolving credit facility, accounts payable and accrued liabilities approximate fair values due to the short-term nature of these items. |
Income Taxes | The Company accounts for income taxes in accordance with Accounting Standards Codification (“ASC”) 740, Income Taxes (“ASC 740”). ASC 740 prescribes the use of the liability method. Deferred tax assets and liabilities are determined based on the difference between the financial statement carrying amounts and the tax basis of assets and liabilities and are measured using the enacted statutory tax rates in effect at the balance sheet date. The Company records a valuation allowance to reduce its deferred tax assets when uncertainty regarding their realizability exists. |
Equity Method Investments | The Company uses the equity method to account for investments in entities that it does not control, but in which it has the ability to exercise significant influence over operating and financial policies. The Company's proportionate share of the net income or loss of these companies is included in consolidated net loss. Judgments regarding the level of influence over each equity method investment include consideration of key factors such as the Company's ownership interest, representation on the board of directors or other management body and participation in policy-making decisions. |
Segment Reporting | The Company’s operations and its financial performance is evaluated on a consolidated basis by the chief operating decision maker. The Company’s chief operating decision maker is the Parent’s Chief Executive Officer. Accordingly, the Company considers all of its operations to be aggregated in one reportable operating segment. For the year ended March 31, 2022, total revenue was $24.1 million, of which $23.4 million was from U.S. operations and $698 thousand was from Japan operations. For the three months ended March 31, 2021, total revenue was $2.4 million, of which $2.0 million was from U.S. operations and $449 thousand was from Japan operations. For the year ended December 31, 2020, total revenue was $11.4 million, of which $10.7 million was from U.S. operations and $713 thousand was from Japan operations. |
Recently Issued Accounting Standards under Evaluation | Recently Issued Accounting Standards under Evaluation Debt - In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, to address the complexity in accounting for certain financial instruments with characteristics of liabilities and equity. Amongst other provisions, the amendments in this ASU significantly change the guidance on the issuer’s accounting for convertible instruments and the guidance on the derivative scope exception for contracts in an entity’s own equity such that fewer conversion features will require separate recognition, and fewer freestanding instruments, like warrants, will require liability treatment. Refer to our white paper, Accounting simplifications for convertible instruments and warrants, for additional information. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements. Leases - In June 2020, the FASB issued ASU 2020-05, which amends the effective dates of the FASB’s standards on leasing (ASC 842) to give immediate relief to certain entities as a result of the widespread adverse economic effects and business disruptions caused by the COVID-19 pandemic. In February 2016, the FASB issued ASU 2016-02, Leases , which, for operating leases, requires the lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, on its balance sheet. The guidance also requires a lessee to recognize single lease costs, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. The leasing standard’s effective dates were the fiscal year beginning after December 15, 2019 as originally issued (ASU 2016-02) and the fiscal year beginning after December 15, 2020 as amended by ASU 2019-10. As amended by ASU 2020-05, the leasing standard’s effective date is now the fiscal year beginning after December 15, 2021. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements. Financial Instruments - FASB ASU 2020-03, Codification Improvements to Financial Instruments , makes clear the determination of the contractual life of a net investment in leases in estimating expected credit losses under ASC 326, Financial Instruments – Credit Losses. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). The standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. ASU 2016-13 is effective for the Company in 2023. Early adoption is permitted. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements. Income Tax - In December 2019, the FASB issued ASU 2019-12, which modifies ASC 740 to simplify the accounting for income taxes. The ASU’s amendments are based on changes that were suggested by stakeholders as part of the FASB’s simplification initiative (i.e., the FASB’s effort to reduce the complexity of accounting standards while maintaining or enhancing the helpfulness of information provided to financial statement users). ASU 2019-12 is effective for fiscal years beginning after December 15, 2022. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements. |

In addition, the CARES Act temporarily increases the business interest deduction limitations from 30% to 50% of adjusted taxable income for the 2019 and 2020 taxable year.
