Accounting Policies [Abstract] | |
Business, Basis of Presentation and Significant Accounting Policies | 1. Business, Basis of Presentation and Significant Accounting Policies Business Magnachip Semiconductor Corporation (together with its subsidiaries, the “Company”) is a designer and manufacturer of analog and mixed-signal semiconductor platform solutions for communications, Internet of Things (“IoT”) applications, consumer, computing, industrial and automotive applications. On September 1, 2020 (the “Closing Date”), the Company completed the sale of the Company’s Foundry Services Group business and its fabrication facility located in Cheongju, Korea, known as “Fab 4” to Key Foundry Co., Ltd. (the “Buyer”), a Korean corporation, in exchange for a purchase price equal to approximately $350.6 million in cash, pursuant to the terms of a business transfer agreement (the “Business Transfer Agreement”) dated March 31, 2020 by and among the Company and Magnus Semiconductor, LLC, a Korean limited liability company (“Magnus”). The purchase price was paid in a combination of U.S. Dollars in the amount of $46.5 million and Korean Won in the amount of approximately KRW 360.6 billion. In addition to the purchase price, the Buyer assumed all severance liabilities relating to the transferred employees, which had a value of approximately $100 million. The Buyer is a wholly owned subsidiary of Magnus, which was established by Alchemist Capital Partners Korea Co., Ltd. and Credian Partners, Inc. On April 20, 2020, Magnus assigned, and the Buyer assumed, all rights and obligations of Magnus under the Business Transfer Agreement. This divestiture of the Foundry Services Group business and Fab 4 was made in connection with the Company’s strategic shift of its operational focus to its standard products business. The Foundry Services Group was historically a reportable segment. The Foundry Services Group business was classified as discontinued operations in the Company’s consolidated statements of operations and excluded from both continuing operations and segment results for all periods presented. Accordingly, the Company has one reportable segment, its standard products business, together with transitional foundry services associated with its fabrication facility located in Gumi, Korea, known as “Fab 3,” that it expects to perform for the Buyer for a period of up to three years from the Closing Date (the “Transitional Fab 3 Foundry Services”). The Company’s standard products business includes its Display Solutions and Power Solutions business lines. The Company’s Display Solutions products provide panel display solutions to major suppliers of large and small rigid and flexible panel displays, and mobile, automotive applications and home appliances. The Company’s Power Solutions products include discrete and integrated circuit solutions for power management in communications, consumer, computing, servers, automotive, and industrial applications. Basis of Presentation The consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Significant accounting policies followed by the Company in the preparation of the accompanying consolidated financial statements are summarized below. The consolidated statements of cash flows for the 2020 and 2019 fiscal years have not been adjusted to separately disclose cash flows related to discontinued operations, but the material items in the operating and investing activities of the cash flow relating to discontinued operations for the same period are disclosed in Note 2. Unless otherwise stated, information in these notes to consolidated financial statements relates to the Company’s continuing operations and excludes the discontinued operations. See Note 2 “Discontinued Operations” for additional information. Principles of Consolidation The consolidated financial statements include the accounts of the Company including its wholly-owned subsidiaries. All intercompany transactions and balances are eliminated in consolidation. Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, stock-based compensation, property, plant and equipment, leases, other long-lived assets, long-term employee benefits, contingencies liabilities, estimated future cash flows and other assumptions used in long-lived asset impairment tests and calculation of current and deferred income taxes and deferred tax valuation allowances, and assumptions used in the calculation of sales incentives, among others. Although these estimates and assumptions are based on management’s best knowledge of current events and actions that the Company may undertake in the future, actual results may be significantly different from the estimates. The Company assessed the impact of COVID-19 COVID-19 COVID-19 Reclassification Certain prior year amounts have been reclassified to conform to the current year presentation. Discontinued Operations The Company reports the results of operations of a business as discontinued operations if a disposal represents a strategic shift that has or will have a major effect on the Company’s operations and financial results when the business is sold and classified as held for sale, in accordance with the criteria of Accounting Standards Codification (“ASC”) 205, “Presentation of Financial Statements” (“ASC 205”) and ASC 360, “Property, Plant and Equipment” (“ASC 360”). The results of discontinued operations are reported in “Income (loss) from discontinued operations, net of tax” in the accompanying consolidated statements of operations for the prior periods commencing in the period in which the business meets the criteria. Foreign Currency Translation The Company has assessed in accordance with ASC 830, “Foreign Currency Matters” (“ASC 830”), the functional currency of each of its subsidiaries in Luxembourg and the Netherlands and has designated the U.S. dollar to be their respective functional currencies. The Korean Won is the functional currency for the Company’s Korean subsidiary, which is the primary operating subsidiary of the Company. The Company and its other subsidiaries are utilizing their local currencies as their functional currencies. The financial statements of the subsidiaries in functional currencies other than the U.S. dollar are translated into the U.S. dollar in accordance with ASC 830. All the assets and liabilities are translated to the U.S. dollar at the end-of-period included in the foreign currency translation adjustment account in accumulated other comprehensive income or loss of stockholders’ equity. Foreign currency translation gains or losses on transactions by the Company or its subsidiaries in a currency other than its or its subsidiaries’ functional currency are included in foreign currency loss, net in its statements of operations. Cash and Cash Equivalents Cash equivalents consist of highly liquid investments with an original maturity date of three months or less when purchased. Accounts Receivable Reserves The Company makes estimates of expected credit losses for the allowance for credit losses based upon its assessment of various factors, including historical collection experience, the age of the accounts receivable balances, current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that may affect its ability to collect from customers. The Company also records an estimate for sales returns, included within accounts receivable, net, based on the historical experience of the amount of goods that will be returned and refunded or replaced. Sales of Accounts Receivable The Company accounts for transfers of financial assets under ASC 860, “Transfers and Servicing,” as either sales or financings. Transfers of financial assets that result in sales accounting are those in which (1) the transfer legally isolates the transferred assets from the transferor, (2) the transferee has the right to pledge or exchange the transferred assets and no condition both constrains the transferee’s right to pledge or exchange the assets and provides more than a trivial benefit to the transferor, and (3) the transferor does not maintain effective control over the transferred assets. If the transfer does not meet these criteria, the transfer is accounted for as a financing. Financial assets that are treated as sales are removed from the Company’s accounts with any realized gain or loss reflected in earning during the period of sale. Inventories Inventories are stated at the lower of cost or net realizable value, using the first in, first out method (“FIFO”). If net realizable value is less than cost at the balance sheet date, the carrying amount is reduced to the realizable value, and the difference is recognized as a loss on valuation of inventories within cost of sales. Inventory reserves are established when conditions indicate that the net realizable value is less than costs due to physical deterioration, obsolescence, changes in price levels, or other causes based on individual facts and circumstances. The Company evaluates the sufficiency of inventory reserves and takes into consideration historical usage, expected demand, anticipated sales price, new product development schedules, the effect new products might have on the sale of existing products, product age and other factors. Reserves are also established for excess inventory based on the Company’s current inventory levels and projected demand and its ability to sell those specific products. Situations that could cause these inventory reserves include a decline in business and economic conditions, decline in consumer confidence caused by changes in market conditions, sudden and significant decline in demand for the Company’s products, inventory obsolescence because of rapidly changing technology and consumer requirements, or failure to estimate end customer demand properly. A reduction of these inventory reserves may be recorded if previously reserved items are subsequently sold as a result of unexpected changes to certain aforementioned situations. In addition, as prescribed in ASC 330, “Inventory,” once a reserve is established for a particular item based on the Company’s assessment as described above, it is maintained until the related item is sold or scrapped as a new cost basis has been established that cannot subsequently be marked up. In addition, the cost of inventories is determined based on the normal capacity of the Company’s fabrication facility. In case the capacity utilization is lower than a certain level that management believes to be normal, the fixed overhead costs per production unit which exceeds those under normal capacity are charged to cost of sales rather than capitalized as inventories. Advances to Suppliers The Company, from time to time, may make advances in form of prepayments or deposits to suppliers to procure materials to meet its planned production. The Company recorded advances of $1,708 thousand and $5,500 thousand as other current assets as of December 31, 2021 and 2020, respectively. Property, Plant and Equipment Property, plant and equipment are stated at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as set forth below. Buildings 30 - 40 years Building related structures 10 - 20 years Machinery and equipment 10 - 12 years Others 3 - 10 years Routine maintenance and repairs are charged to expense as incurred. Expenditures that enhance the value or significantly extend the useful lives of the related assets are capitalized. Impairment of Long-Lived Assets The Company reviews property, plant and equipment and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable in accordance with ASC 360, “Property, Plant and Equipment.” Recoverability is measured by comparing its carrying amount with the future net undiscounted cash flows the assets are expected to generate. If such assets are considered to be impaired, the impairment is measured as the difference between the carrying amount of the assets and the fair value of assets using the present value of the future net cash flows generated by the respective long-lived assets. Leases The Company determines if an arrangement is a lease at inception of a contract considering whether the arrangement conveys the right to control the use of an identified asset over the period of use. Control of an underlying asset is conveyed if the Company has the right to direct the use of, and to obtain substantially all of the economic benefits from the use of, the identified asset. The Company accounts for lease transactions as either an operating or a finance lease, depending on the terms of the underlying lease arrangement. Assets related to operating leases are recorded on the balance sheet as operating lease right-of-use non-current non-current right-of-use non-current Right-of-use Right-of-use right-of-use right-of-use An extension or contraction of a lease term is considered if the related option to extend or early terminate the lease is reasonably certain to be exercised by the Company. Operating lease right-of-use non-lease non-lease Variable lease payment amounts that cannot be determined at the commencement of the lease such as increases in lease payments based on changes in index rates are not included in the right-of-use The Company does not recognize operating lease right-of-use Intangible Assets Intellectual property assets acquired represent rights under patents, trademarks and property use rights and are amortized over their respective periods of benefit, ranging up to ten years, on a straight-line basis. Fair Value Disclosures of Financial Instruments The Company follows ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”) for measurement and disclosures about fair value of its financial instruments. ASC 820 establishes a framework for measuring fair value in U.S. GAAP, and expands disclosures about fair value measurements. To increase consistency and comparability in fair value measurements and related disclosures, ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The three levels of fair value hierarchy defined by ASC 820 are: Level 1—Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2—Inputs (other than quoted market prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. Level 3—Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Valuation of instruments includes unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities. As defined by ASC 820, the fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale, which was further clarified as the price that would be received to sell an asset or paid to transfer a liability (“an exit price”) in an orderly transaction between market participants at the measurement date. The carrying amounts of the Company’s financial assets and liabilities, such as cash equivalents, accounts receivable, other receivables, accounts payable and other accounts payable approximate their fair values because of the short maturity of these instruments. Accrued Severance Benefits The majority of accrued severance benefits are for employees in the Company’s Korean subsidiary, Magnachip Semiconductor, Ltd. Pursuant to the Employee Retirement Benefit Security Act of Korea, eligible employees and executive officers with one or more years of service are entitled to severance benefits upon the termination of their employment based on their length of service and rate of pay. As of December 31, 2021, 98% of all employees of the Company were eligible for severance benefits. Beginning in July 2018, the Company began contributing to certain severance insurance deposit accounts a percentage of severance benefits, which may be adjusted from time to time, accrued for eligible employees for their services beginning January 1, 2018. These accounts consist of time deposits and other guaranteed principal and interest accounts, and are maintained at insurance companies, banks or security companies for the benefit of the Company’s employees. Accrued severance benefits are partly funded through a group severance insurance plan. The amounts funded under this insurance plan are classified as a reduction of the accrued severance benefits. Subsequent accruals are to be funded at the discretion of the Company. In accordance with the National Pension Act of the Republic of Korea, a certain portion of accrued severance benefits is deposited with the National Pension Fund and deducted from the accrued severance benefits. The contributed amount is paid to employees from the National Pension Fund upon their retirement. Revenue Recognition The Company recognizes revenue when it satisfies the performance obligation of transferring control over a product or service to a customer. Revenue is measured based on the consideration specified in a contract with a customer, which consideration is paid in exchange for a product or service. The Company sells products manufactured based on the Company’s design. The Company’s products are either standardized with an alternative use or the Company does not have an enforceable right to payment for the related manufacturing services completed to date. Therefore, revenue for the products is recognized when a customer obtains control of the product, which is generally upon product shipment, delivery at the customer’s location or upon customer acceptance, depending on the terms of the arrangement. In accordance with revenue recognition guidance, any tax assessed by a governmental authority that is both imposed on and concurrent with a specific revenue-producing transaction, and that is collected by the Company from a customer, is excluded from revenue and related revenue is presented in the statements of operations on a net basis. The Company provides warranties under which customers can return defective products. The Company estimates the costs related to warranty claims and repair or replacements, and records them as components of cost of sales. In addition, the Company offers sales returns (other than those that relate to defective products under warranty), cash discounts for early payments and sales incentives, and certain allowances to the Company’s customers, including the Company’s distributors. The Company records reserves for those returns, discounts, incentives and allowances as a deduction from sales, based on historical experience and other quantitative and qualitative factors. Substantially all of the Company’s contracts are one year or less in duration. The standard payment terms with customers are generally thirty to sixty days from the time of shipment, product delivery to the customer’s location or customer acceptance, depending on the terms of the related arrangement. All amounts billed to a customer related to shipping and handling are classified as sales while all costs incurred by the Company for shipping and handling are classified as selling, general and administrative expenses. The amounts charged to selling, general and administrative expenses were $1,271 thousand, $993 thousand and $990 thousand for the years ended December 31, 2021, 2020 and 2019, respectively. Of the recorded deferred revenue of $2,680 thousand as of December 31, 2020 and $559 thousand as of December 31, 2019, $2,680 thousand and $559 thousand were recognized as revenue during the years ended December 31, 2021 and 2020, respectively. Advertising The Company expenses advertising costs as incurred. Advertising expenses were $71 thousand, $87 thousand and $62 thousand for the years ended December 31, 2021, 2020 and 2019, respectively. Product Warranties The Company records, in other current liabilities, warranty liabilities for the estimated costs that may be incurred under its basic limited warranty. The standard limited warranty period is one to two years for the majority of products. This warranty covers defective products, and related liabilities are accrued when product revenues are recognized. Factors that affect the Company’s warranty liabilities include historical and anticipated rates of warranty claims and repair or replacement costs per claim to satisfy the Company’s warranty obligation. The Company periodically assesses the adequacy of those recorded warranty liabilities and adjusts its estimates when necessary. Derivative Financial Instruments The Company applies the provisions of ASC 815, “Derivatives and Hedging” (“ASC 815”). This statement requires the recognition of all derivative instruments as either assets or liabilities measured at fair value. Under the provisions of ASC 815, the Company may designate a derivative instrument as hedging the exposure to variability in expected future cash flows that are attributable to a particular risk (a “cash flow hedge”) or hedging the exposure to changes in the fair value of an asset or a liability (a “fair value hedge”). Special accounting for qualifying hedges allows the effective portion of a derivative instrument’s gains and losses to offset related results on the hedged item in the consolidated statements of operations and requires that a company formally document, designate and assess the effectiveness of the transactions that receive hedge accounting treatment. Both at the inception of a hedge and on an ongoing basis, a hedge must be expected to be highly effective in achieving offsetting changes in cash flows or fair value attributable to the underlying risk being hedged. If the Company determines that a derivative instrument is no longer highly effective as a hedge, it discontinues hedge accounting prospectively and future changes in the fair value of the derivative are recognized in current earnings. The Company assesses hedge effectiveness at the end of each quarter. The Company does not offset derivative assets and liabilities within the consolidated balance sheets. In accordance with ASC 815, changes in the fair value of derivative instruments that are cash flow hedges are recognized in accumulated other comprehensive income (loss) and reclassified into earnings in the period in which the hedged item affects earnings. Derivative instruments that do not qualify, or cease to qualify, as hedges must be adjusted to fair value and the adjustments are recorded through net income (loss). The cash flows from derivative instruments receiving hedge accounting treatment are classified in the same categories as the hedged items in the consolidated statements of cash flows. Research and Development Research and development expenses are expensed as incurred and include wafers, masks, employee expenses, contractor fees, building costs, utilities and administrative expenses. Licensed Patents and Technologies The Company has entered into a number of royalty agreements to license patents and technology used in the design of its products. The Company carries two types of royalties: lump-sum Lump-sum non-refundable Running royalties are paid based on the revenue of related products sold by the Company. Stock-Based Compensation The Company follows the provisions of ASC 718, “Compensation-Stock Compensation” (“ASC 718”). Under ASC 718, stock-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense, net of the estimated forfeiture rate, over the requisite service period. As permitted under ASC 718, the Company elected to recognize compensation expense for all options with graded vesting based on the graded attribution method. The Company uses the Black-Scholes option-pricing model to measure the grant-date-fair-value of options. The Black-Scholes model requires certain assumptions to determine an option’s fair value, including expected term, risk free interest rate and expected volatility. The expected term of each option grant was based on employees’ expected exercises and post-vesting employment termination behavior and the risk free interest rate was based on the U.S. Treasury yield curve for the period corresponding with the expected term at the time of grant. No dividends were assumed for this calculation of option value. Earnings Per Share In accordance with ASC 260, “Earnings Per Share”, the Company computes basic earnings per share by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect the dilution of potential common stock outstanding during the period including stock options and restricted stock units, using the treasury stock method (by using the average stock price for the period to determine the number of shares assumed to be purchased from the exercise of stock options and restricted stock units), and convertibles, using the if-converted Income Taxes The Company accounts for income taxes in accordance with ASC 740, “Income Taxes” (“ASC 740”). ASC 740 requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in a company’s financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based upon the difference between the financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Income tax expense is the tax payable for the period and the change during the period in deferred tax assets and liabilities. Valuation allowances are established when it is necessary to reduce deferred tax assets to the amount expected to be realized. The evaluation of the recoverability of the deferred tax assets and the need for a valuation allowance requires management to weigh all positive and negative evidence to reach a conclusion that it is more likely than not that all or some portion of the deferred tax assets will not be realized. Realization of the future tax benefits related to the deferred tax assets is dependent on many factors, including historical operating results, expected timing of the reversals of existing temporary differences, the Company’s ability to generate future taxable income, and tax planning strategies. The Company recognizes and measures uncertain tax positions taken or expected to be taken in a tax return utilizing a two-step Concentration of Credit Risk The Company performs periodic credit evaluations of its customers’ financial condition and generally does not require collateral for customers on accounts receivable. The Company maintains reserves for potential credit losses, which are periodically reviewed.

Fair Value Measurements | 3. Fair Value Measurements ASC 820 defines fair value, establishes a consistent framework for measuring fair value and expands disclosure requirements about fair value measurements. ASC 820 requires, among other things, the Company’s valuation techniques used to measure fair value to maximize the use of observable inputs and minimize the use of unobservable inputs. Fair Value of Financial Instruments As of December 31, 2021, the following table represents the Company’s liabilities measured at fair value on a recurring basis and the basis for that measurement (in thousands): Carrying Value Fair Value Quoted Prices in Significant Significant Liabilities: Derivative liabilities (other current liabilities) $ 2,020 $ 2,020 — $ 2,020 — As of December 31, 2020, the following table represents the Company’s assets and liabilities measured at fair value on a recurring basis and the basis for that measurement (in thousands): Carrying Value Fair Value Quoted Prices in Significant Significant Assets: Derivative assets (other current assets) $ 2,036 $ 2,036 — $ 2,036 — Liabilities: Derivative liabilities (other current liabilities) $ 195 $ 195 — $ 195 — Items not reflected in the table above include cash equivalents, accounts receivable, other receivables, accounts payable, and other accounts payable, fair value of which approximate carrying values due to the short-term nature of these instruments. The fair value of assets and liabilities whose carrying value approximates fair value is determined using Level 2 inputs.

Income Taxes | 17. Income Taxes The Company’s income tax expense (benefit) is composed of domestic and foreign income taxes depending on the relevant tax jurisdictions. Domestic income (loss) from continuing operations before income tax expense and income tax expense (benefit) are generated or incurred in the U.S, where the parent company resides. The components of income tax expense (benefit) attributable to income (loss) from continuing operations are as follows (in thousands): Year Ended December 31, 2021 2020 2019 Income (loss) from continuing operations before income tax expense Domestic $ 41,566 $ (12,305 ) $ (24,752 ) Foreign 32,403 23,136 6,539 73,969 10,831 (18,213 ) Current income tax expense (benefit) Domestic 6,876 1 20 Foreign 9,415 (2,264 ) 3,771 Uncertain tax position liability (domestic) — — (1 ) Uncertain tax position liability (foreign) (35 ) (20 ) 2 16,256 (2,283 ) 3,792 Deferred income tax benefit Domestic 1,314 (4,461 ) — Foreign (309 ) (39,484 ) 63 1,005 (43,945 ) 63 Benefits from intra-period allocation — — (1,655 ) Total income tax expense (benefit) $ 17,261 $ (46,228 ) $ 2,200 Effective tax rate 23.3 % — — The Company’s effective tax rate for the year ended December 31, 2021 was 23.3% as compared to negative effective tax rates for the years ended December 31, 2020 and 2019. The Company’s effective tax rate in 2021 was higher than the U.S. federal statutory rate of 21.0%, primarily due to the earnings from its operating subsidiary in Korea at a higher statutory tax rate. The increase in the effective tax rate in 2021 was primarily due to the higher taxable income from the Korean subsidiary and the reverse termination fee income recognized by the parent entity in the U.S. in relation to the Merger. The negative effective tax rate in 2020 as compared to the U.S. federal statutory rate of 21.0%, was primarily attributable to the reversal of the valuation allowances established against the deferred tax assets in connection with the Company’s operating subsidiary in Korea and parent entity in the U.S. The difference between the annual effective income tax rate and the U.S. federal statutory rate of 21.0% in 2019 primarily related to the non-income non-taxable The Company’s Korean subsidiary recorded $1,655 thousand income tax benefits for the year ended December 31, 2019, primarily attributable to the application of the exception rule under ASC 740, in connection with the intra-period allocation, which resulted in the tax benefit in its continuing operations and tax expense in the discontinued operations for an equal and offsetting amount for the presentation purposes only. The provision for domestic and foreign income taxes incurred is different from the amount calculated by applying the statutory tax rates to the income (loss) from continuing operations before income tax expense. The significant items causing this difference are as follows (in thousands): Year Ended December 31, 2021 2020 2019 Provision computed at statutory rates $ 15,533 $ 2,274 $ (3,825 ) State income taxes, net of federal effect — 730 (1,139 ) Change in statutory tax rates (259 ) 5,735 2,329 Difference in foreign tax rates 2,820 1,077 3,002 Permanent differences Derivative assets adjustment (23 ) 56 315 TPECs, hybrid and other interest (3,400 ) (2,722 ) 7,812 Thin capitalization — 339 988 Equity-based compensation (802 ) (73 ) (14 ) Permanent foreign currency gain (loss) 1,888 (1,813 ) (1,734 ) Penalty 427 176 151 GILTI 6,156 24,224 5,112 Intercompany debt restructuring 971 11,137 (18,435 ) Other permanent differences (767 ) 1,335 408 Withholding tax 2,060 2,291 3,043 State net operating loss write-off 9,844 — — Change in valuation allowance (13,803 ) (75,452 ) 7,817 Benefits from intra-period allocation — — (1,655 ) Tax credits claimed (5,508 ) (12,397 ) (651 ) Tax credits expired — — 170 Uncertain tax positions liability (35 ) (20 ) 1 Change in net operating loss carry-forwards 621 (3,314 ) — Foreign local taxes 723 43 152 Others 815 146 (1,647 ) Income tax expense (benefit) $ 17,261 $ (46,228 ) $ 2,200 Of the income tax benefit of $13,803 thousand attributable to the change in valuation allowances during the year ended December 31, 2021, $9,844 thousand is related to the release of the valuation allowance established against the deferred tax assets associated in the U.S. entity due to the dissolution of the Company’s domestic subsidiary in 2021 subsequent to the sale of the Foundry Services Group business and Fab 4. The offsetting expense of $9,844 thousand was included in the state net operating loss write-off $3,959 thousand represented the release of valuation allowances based on the assessment of the realizability of the related deferred tax assets in future tax years. For the year ended December 31, 2020, a permanent difference of $24,224 thousand was included as Global intangible low-taxed Fab 4. The income tax benefit of $75,452 thousand was due to the changes in valuation allowances during the year ended December 31, 2020, of which $31,578 thousand related to the release of valuation allowances related to the Company’s current year earnings, which were mainly driven by GILTI inclusion at the U.S. parent company. The remaining $43,874 thousand represented the release of valuation allowances based on the realizability of the related deferred tax assets in future years. The Company’s operating subsidiary in Korea had generated three years of cumulative profits adjusted for permanent differences and is anticipated to generate taxable basis for the subsequent years. As a result, $39,413 thousand of valuation allowances, established against the Korean subsidiary’s deferred tax assets, were released as of December 31, 2020. In addition, management believes it is more likely than not that the Company’s parent in the U.S. would be able to utilize its net operating loss in future tax years, which would provide incremental tax savings of approximately $4,461 thousand. Therefore, the Company released its valuation allowances established against the U.S. parent’s deferred tax assets up to these anticipated tax savings as of December 31, 2020. Of the permanent tax expense of $11,137 thousand related to intercompany debt restructuring recorded for the year ended December 31, 2020, $11,890 thousand related to the waiver and release of unpaid interests of the intercompany loans granted to the Korean subsidiary by the Dutch subsidiary. This transaction created taxable income for the Korean subsidiary, but did not result in a liability because of the utilization of loss carryforwards, which were used against income from cancellation of intercompany loans. During 2019, the Company completed a restructuring of its intercompany borrowings between the Company and the other entities within the group of the Company. The main purpose of this restructuring was to simplify the intercompany debt structure of the group in order to align with the anti-hybrid mismatch provision mandated by the Organization for Economic Co-operation A summary of the composition of net deferred income tax assets (liabilities) as of December 31, 2021 and 2020 are as follows (in thousands): Year Ended December 31, 2021 2020 Deferred tax assets Inventory reserves $ 1,313 $ 1,338 Accrued expenses 3,084 2,493 Property, plant and equipment 3,119 3,391 Accumulated severance benefits 11,842 12,343 Operating lease right-of-use 899 1,025 Foreign currency translation loss 17,280 9,129 NOL carry-forwards 87,636 121,389 Tax credit carry-forwards 14,164 15,395 Other long-term payable 2,457 944 Interest expense deduction limitation 4,731 — Derivative liabilities 463 — Others 1,610 1,629 Total deferred tax assets 148,598 169,076 Less: Valuation allowance (94,212 ) (115,636 ) 54,386 53,440 Deferred tax liabilities Derivative assets — 417 Prepaid expense 2,300 1,071 Severance benefit deposits 4,227 3,156 Operating lease right-of-use 899 1,025 Foreign currency translation gain 5,139 2,431 Others 726 799 Total deferred tax liabilities 13,291 8,899 Net deferred tax assets $ 41,095 $ 44,541 The Company has not recognized a deferred tax liability related to outside basis differences inherent in its foreign subsidiaries because the investments in those foreign subsidiaries within the group are essentially permanent in duration or earnings in foreign subsidiaries are intended to be indefinitely reinvested. It is not practicable to estimate the amount of deferred income taxes not recorded that are associated with those outside basis differences. If circumstances change and it becomes apparent that the undistributed earnings from foreign subsidiaries will be remitted or the parent entity will dispose of its interest in the subsidiaries in the foreseeable future, and related income taxes have not been recognized by the parent entity, the parent entity will accrue as an expense of the current period income taxes attributable to that remittance or disposition. Changes in valuation allowance for deferred tax assets of continuing operations and discontinued operations for the years ended December 31, 2021, 2020 and 2019 are as follows (in thousands): Year Ended December 31, 2021 2020 2019 Beginning balance $ 115,636 $ 246,224 $ 248,633 Additions — — 7,912 Reductions (13,803 ) (75,452 ) — Changes relating to the discontinued operations — (67,484 ) — NOL/tax credit claimed/expired — 3,686 (3,529 ) Translation adjustments (7,621 ) 8,662 (6,792 ) Ending balance $ 94,212 $ 115,636 $ 246,224 As of December 31, 2021, 2020 and 2019, respectively, the Company recorded a valuation allowance of $94,212 thousand, $115,636 thousand and $246,224 thousand on its deferred tax assets related to temporary differences, net operating loss carry-forwards and tax credits of domestic and foreign subsidiaries. The Company has recorded a full valuation allowance against certain foreign subsidiaries’ deferred tax assets pertaining to its related tax loss carry-forwards that are not anticipated to generate a tax benefit. The valuation allowances at December 31, 2021, 2020 and 2019 were primarily attributable to its Luxembourg subsidiary. Year Ended December 31, 2021 2020 2019 NOL carry-forwards $ 502,511 $ 604,977 $ 708,885 As of December 31, 2021, the Company had $502,511 thousand of net operating loss carry-forwards available to offset future taxable income, of which $288,548 thousand is associated with the Company’s Luxembourg subsidiary, mainly attributable to certain expenses incurred in connection with its shareholding in the Company’s Dutch subsidiary. Of the $288,548 thousand net operating loss carry-forwards, $279,848 thousand is carried forward indefinitely and the remaining $8,700 thousand expires from 2034 through 2037. The net operating loss carry-forwards retained by the Company’s U.S. parent and its domestic subsidiary (which was closed in 2021 subsequent to the sale of the Foundry Services Group business and Fab 4) amounts to $198,813 thousand, which expires at various dates through 2040. The amount associated with the Company’s Korean subsidiary of $11,499 thousand expires in 2026. The Company utilized net operating loss of $70,672 thousand, $169,600 thousand and $30,945 thousand for the years ended December 31, 2021, 2020 and 2019, respectively. The Company also has Dutch tax credit carry-forwards of approximately $14,164 thousand as of December 31, 2021. The Dutch tax credits are carried forward to be used for an indefinite period of time. Uncertainty in Income Taxes The Company and its subsidiaries file income tax returns in Korea, Japan, Taiwan, and the U.S. and in various other jurisdictions. The Company is subject to income- or non-income tax years. As of December 31, 2021, 2020 and 2019, the Company recorded $386 thousand, $414 thousand and $445 thousand of unrecognized tax benefits of continuing operations and discontinued operations, respectively. A tabular reconciliation of the total amounts of unrecognized tax benefits at the beginning and end of each period is as follows (in thousands): Year Ended December 31, 2021 2020 2019 Unrecognized tax benefits, balance at the beginning $ 414 $ 445 $ 426 Additions based on tax positions related to the current year 44 48 13 Reductions for tax positions of prior years — (34 ) (1 ) Lapse of statute of limitations (79 ) (76 ) — Translation adjustments 7 31 7 Unrecognized tax benefits, balance at the ending $ 386 $ 414 $ 445 No interest and penalties related to unrecognized tax benefits were recognized as of December , , and .

Accounting Policies [Abstract] | |
Business | Business Magnachip Semiconductor Corporation (together with its subsidiaries, the “Company”) is a designer and manufacturer of analog and mixed-signal semiconductor platform solutions for communications, Internet of Things (“IoT”) applications, consumer, computing, industrial and automotive applications. On September 1, 2020 (the “Closing Date”), the Company completed the sale of the Company’s Foundry Services Group business and its fabrication facility located in Cheongju, Korea, known as “Fab 4” to Key Foundry Co., Ltd. (the “Buyer”), a Korean corporation, in exchange for a purchase price equal to approximately $350.6 million in cash, pursuant to the terms of a business transfer agreement (the “Business Transfer Agreement”) dated March 31, 2020 by and among the Company and Magnus Semiconductor, LLC, a Korean limited liability company (“Magnus”). The purchase price was paid in a combination of U.S. Dollars in the amount of $46.5 million and Korean Won in the amount of approximately KRW 360.6 billion. In addition to the purchase price, the Buyer assumed all severance liabilities relating to the transferred employees, which had a value of approximately $100 million. The Buyer is a wholly owned subsidiary of Magnus, which was established by Alchemist Capital Partners Korea Co., Ltd. and Credian Partners, Inc. On April 20, 2020, Magnus assigned, and the Buyer assumed, all rights and obligations of Magnus under the Business Transfer Agreement. This divestiture of the Foundry Services Group business and Fab 4 was made in connection with the Company’s strategic shift of its operational focus to its standard products business. The Foundry Services Group was historically a reportable segment. The Foundry Services Group business was classified as discontinued operations in the Company’s consolidated statements of operations and excluded from both continuing operations and segment results for all periods presented. Accordingly, the Company has one reportable segment, its standard products business, together with transitional foundry services associated with its fabrication facility located in Gumi, Korea, known as “Fab 3,” that it expects to perform for the Buyer for a period of up to three years from the Closing Date (the “Transitional Fab 3 Foundry Services”). The Company’s standard products business includes its Display Solutions and Power Solutions business lines. The Company’s Display Solutions products provide panel display solutions to major suppliers of large and small rigid and flexible panel displays, and mobile, automotive applications and home appliances. The Company’s Power Solutions products include discrete and integrated circuit solutions for power management in communications, consumer, computing, servers, automotive, and industrial applications. |
Basis of Presentation | Basis of Presentation The consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Significant accounting policies followed by the Company in the preparation of the accompanying consolidated financial statements are summarized below. The consolidated statements of cash flows for the 2020 and 2019 fiscal years have not been adjusted to separately disclose cash flows related to discontinued operations, but the material items in the operating and investing activities of the cash flow relating to discontinued operations for the same period are disclosed in Note 2. Unless otherwise stated, information in these notes to consolidated financial statements relates to the Company’s continuing operations and excludes the discontinued operations. See Note 2 “Discontinued Operations” for additional information. |
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of the Company including its wholly-owned subsidiaries. All intercompany transactions and balances are eliminated in consolidation. |
Use of Estimates | Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, stock-based compensation, property, plant and equipment, leases, other long-lived assets, long-term employee benefits, contingencies liabilities, estimated future cash flows and other assumptions used in long-lived asset impairment tests and calculation of current and deferred income taxes and deferred tax valuation allowances, and assumptions used in the calculation of sales incentives, among others. Although these estimates and assumptions are based on management’s best knowledge of current events and actions that the Company may undertake in the future, actual results may be significantly different from the estimates. The Company assessed the impact of COVID-19 COVID-19 COVID-19 |
Reclassifications | Reclassification Certain prior year amounts have been reclassified to conform to the current year presentation. |
Discontinued Operations | Discontinued Operations The Company reports the results of operations of a business as discontinued operations if a disposal represents a strategic shift that has or will have a major effect on the Company’s operations and financial results when the business is sold and classified as held for sale, in accordance with the criteria of Accounting Standards Codification (“ASC”) 205, “Presentation of Financial Statements” (“ASC 205”) and ASC 360, “Property, Plant and Equipment” (“ASC 360”). The results of discontinued operations are reported in “Income (loss) from discontinued operations, net of tax” in the accompanying consolidated statements of operations for the prior periods commencing in the period in which the business meets the criteria. |
Foreign Currency Translation | Foreign Currency Translation The Company has assessed in accordance with ASC 830, “Foreign Currency Matters” (“ASC 830”), the functional currency of each of its subsidiaries in Luxembourg and the Netherlands and has designated the U.S. dollar to be their respective functional currencies. The Korean Won is the functional currency for the Company’s Korean subsidiary, which is the primary operating subsidiary of the Company. The Company and its other subsidiaries are utilizing their local currencies as their functional currencies. The financial statements of the subsidiaries in functional currencies other than the U.S. dollar are translated into the U.S. dollar in accordance with ASC 830. All the assets and liabilities are translated to the U.S. dollar at the end-of-period included in the foreign currency translation adjustment account in accumulated other comprehensive income or loss of stockholders’ equity. Foreign currency translation gains or losses on transactions by the Company or its subsidiaries in a currency other than its or its subsidiaries’ functional currency are included in foreign currency loss, net in its statements of operations. |
Cash and Cash Equivalents | Cash and Cash Equivalents Cash equivalents consist of highly liquid investments with an original maturity date of three months or less when purchased. |
Accounts Receivable Reserves | Accounts Receivable Reserves The Company makes estimates of expected credit losses for the allowance for credit losses based upon its assessment of various factors, including historical collection experience, the age of the accounts receivable balances, current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that may affect its ability to collect from customers. The Company also records an estimate for sales returns, included within accounts receivable, net, based on the historical experience of the amount of goods that will be returned and refunded or replaced. |
Sales of Accounts Receivable | Sales of Accounts Receivable The Company accounts for transfers of financial assets under ASC 860, “Transfers and Servicing,” as either sales or financings. Transfers of financial assets that result in sales accounting are those in which (1) the transfer legally isolates the transferred assets from the transferor, (2) the transferee has the right to pledge or exchange the transferred assets and no condition both constrains the transferee’s right to pledge or exchange the assets and provides more than a trivial benefit to the transferor, and (3) the transferor does not maintain effective control over the transferred assets. If the transfer does not meet these criteria, the transfer is accounted for as a financing. Financial assets that are treated as sales are removed from the Company’s accounts with any realized gain or loss reflected in earning during the period of sale. |
Inventories | Inventories Inventories are stated at the lower of cost or net realizable value, using the first in, first out method (“FIFO”). If net realizable value is less than cost at the balance sheet date, the carrying amount is reduced to the realizable value, and the difference is recognized as a loss on valuation of inventories within cost of sales. Inventory reserves are established when conditions indicate that the net realizable value is less than costs due to physical deterioration, obsolescence, changes in price levels, or other causes based on individual facts and circumstances. The Company evaluates the sufficiency of inventory reserves and takes into consideration historical usage, expected demand, anticipated sales price, new product development schedules, the effect new products might have on the sale of existing products, product age and other factors. Reserves are also established for excess inventory based on the Company’s current inventory levels and projected demand and its ability to sell those specific products. Situations that could cause these inventory reserves include a decline in business and economic conditions, decline in consumer confidence caused by changes in market conditions, sudden and significant decline in demand for the Company’s products, inventory obsolescence because of rapidly changing technology and consumer requirements, or failure to estimate end customer demand properly. A reduction of these inventory reserves may be recorded if previously reserved items are subsequently sold as a result of unexpected changes to certain aforementioned situations. In addition, as prescribed in ASC 330, “Inventory,” once a reserve is established for a particular item based on the Company’s assessment as described above, it is maintained until the related item is sold or scrapped as a new cost basis has been established that cannot subsequently be marked up. In addition, the cost of inventories is determined based on the normal capacity of the Company’s fabrication facility. In case the capacity utilization is lower than a certain level that management believes to be normal, the fixed overhead costs per production unit which exceeds those under normal capacity are charged to cost of sales rather than capitalized as inventories. |
Advances to Suppliers | Advances to Suppliers The Company, from time to time, may make advances in form of prepayments or deposits to suppliers to procure materials to meet its planned production. The Company recorded advances of $1,708 thousand and $5,500 thousand as other current assets as of December 31, 2021 and 2020, respectively. |
Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment are stated at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as set forth below. Buildings 30 - 40 years Building related structures 10 - 20 years Machinery and equipment 10 - 12 years Others 3 - 10 years Routine maintenance and repairs are charged to expense as incurred. Expenditures that enhance the value or significantly extend the useful lives of the related assets are capitalized. |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company reviews property, plant and equipment and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable in accordance with ASC 360, “Property, Plant and Equipment.” Recoverability is measured by comparing its carrying amount with the future net undiscounted cash flows the assets are expected to generate. If such assets are considered to be impaired, the impairment is measured as the difference between the carrying amount of the assets and the fair value of assets using the present value of the future net cash flows generated by the respective long-lived assets. |
Leases | Leases The Company determines if an arrangement is a lease at inception of a contract considering whether the arrangement conveys the right to control the use of an identified asset over the period of use. Control of an underlying asset is conveyed if the Company has the right to direct the use of, and to obtain substantially all of the economic benefits from the use of, the identified asset. The Company accounts for lease transactions as either an operating or a finance lease, depending on the terms of the underlying lease arrangement. Assets related to operating leases are recorded on the balance sheet as operating lease right-of-use non-current non-current right-of-use non-current Right-of-use Right-of-use right-of-use right-of-use An extension or contraction of a lease term is considered if the related option to extend or early terminate the lease is reasonably certain to be exercised by the Company. Operating lease right-of-use non-lease non-lease Variable lease payment amounts that cannot be determined at the commencement of the lease such as increases in lease payments based on changes in index rates are not included in the right-of-use The Company does not recognize operating lease right-of-use |
Intangible Assets | Intangible Assets Intellectual property assets acquired represent rights under patents, trademarks and property use rights and are amortized over their respective periods of benefit, ranging up to ten years, on a straight-line basis. |
Fair Value Disclosures of Financial Instruments | Fair Value Disclosures of Financial Instruments The Company follows ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”) for measurement and disclosures about fair value of its financial instruments. ASC 820 establishes a framework for measuring fair value in U.S. GAAP, and expands disclosures about fair value measurements. To increase consistency and comparability in fair value measurements and related disclosures, ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The three levels of fair value hierarchy defined by ASC 820 are: Level 1—Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2—Inputs (other than quoted market prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. Level 3—Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Valuation of instruments includes unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities. As defined by ASC 820, the fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale, which was further clarified as the price that would be received to sell an asset or paid to transfer a liability (“an exit price”) in an orderly transaction between market participants at the measurement date. The carrying amounts of the Company’s financial assets and liabilities, such as cash equivalents, accounts receivable, other receivables, accounts payable and other accounts payable approximate their fair values because of the short maturity of these instruments. |
Accrued Severance Benefits | Accrued Severance Benefits The majority of accrued severance benefits are for employees in the Company’s Korean subsidiary, Magnachip Semiconductor, Ltd. Pursuant to the Employee Retirement Benefit Security Act of Korea, eligible employees and executive officers with one or more years of service are entitled to severance benefits upon the termination of their employment based on their length of service and rate of pay. As of December 31, 2021, 98% of all employees of the Company were eligible for severance benefits. Beginning in July 2018, the Company began contributing to certain severance insurance deposit accounts a percentage of severance benefits, which may be adjusted from time to time, accrued for eligible employees for their services beginning January 1, 2018. These accounts consist of time deposits and other guaranteed principal and interest accounts, and are maintained at insurance companies, banks or security companies for the benefit of the Company’s employees. Accrued severance benefits are partly funded through a group severance insurance plan. The amounts funded under this insurance plan are classified as a reduction of the accrued severance benefits. Subsequent accruals are to be funded at the discretion of the Company. In accordance with the National Pension Act of the Republic of Korea, a certain portion of accrued severance benefits is deposited with the National Pension Fund and deducted from the accrued severance benefits. The contributed amount is paid to employees from the National Pension Fund upon their retirement. |
Revenue Recognition | Revenue Recognition The Company recognizes revenue when it satisfies the performance obligation of transferring control over a product or service to a customer. Revenue is measured based on the consideration specified in a contract with a customer, which consideration is paid in exchange for a product or service. The Company sells products manufactured based on the Company’s design. The Company’s products are either standardized with an alternative use or the Company does not have an enforceable right to payment for the related manufacturing services completed to date. Therefore, revenue for the products is recognized when a customer obtains control of the product, which is generally upon product shipment, delivery at the customer’s location or upon customer acceptance, depending on the terms of the arrangement. In accordance with revenue recognition guidance, any tax assessed by a governmental authority that is both imposed on and concurrent with a specific revenue-producing transaction, and that is collected by the Company from a customer, is excluded from revenue and related revenue is presented in the statements of operations on a net basis. The Company provides warranties under which customers can return defective products. The Company estimates the costs related to warranty claims and repair or replacements, and records them as components of cost of sales. In addition, the Company offers sales returns (other than those that relate to defective products under warranty), cash discounts for early payments and sales incentives, and certain allowances to the Company’s customers, including the Company’s distributors. The Company records reserves for those returns, discounts, incentives and allowances as a deduction from sales, based on historical experience and other quantitative and qualitative factors. Substantially all of the Company’s contracts are one year or less in duration. The standard payment terms with customers are generally thirty to sixty days from the time of shipment, product delivery to the customer’s location or customer acceptance, depending on the terms of the related arrangement. All amounts billed to a customer related to shipping and handling are classified as sales while all costs incurred by the Company for shipping and handling are classified as selling, general and administrative expenses. The amounts charged to selling, general and administrative expenses were $1,271 thousand, $993 thousand and $990 thousand for the years ended December 31, 2021, 2020 and 2019, respectively. Of the recorded deferred revenue of $2,680 thousand as of December 31, 2020 and $559 thousand as of December 31, 2019, $2,680 thousand and $559 thousand were recognized as revenue during the years ended December 31, 2021 and 2020, respectively. |
Advertising | Advertising The Company expenses advertising costs as incurred. Advertising expenses were $71 thousand, $87 thousand and $62 thousand for the years ended December 31, 2021, 2020 and 2019, respectively. |
Product Warranties | Product Warranties The Company records, in other current liabilities, warranty liabilities for the estimated costs that may be incurred under its basic limited warranty. The standard limited warranty period is one to two years for the majority of products. This warranty covers defective products, and related liabilities are accrued when product revenues are recognized. Factors that affect the Company’s warranty liabilities include historical and anticipated rates of warranty claims and repair or replacement costs per claim to satisfy the Company’s warranty obligation. The Company periodically assesses the adequacy of those recorded warranty liabilities and adjusts its estimates when necessary. |
Derivative Financial Instruments | Derivative Financial Instruments The Company applies the provisions of ASC 815, “Derivatives and Hedging” (“ASC 815”). This statement requires the recognition of all derivative instruments as either assets or liabilities measured at fair value. Under the provisions of ASC 815, the Company may designate a derivative instrument as hedging the exposure to variability in expected future cash flows that are attributable to a particular risk (a “cash flow hedge”) or hedging the exposure to changes in the fair value of an asset or a liability (a “fair value hedge”). Special accounting for qualifying hedges allows the effective portion of a derivative instrument’s gains and losses to offset related results on the hedged item in the consolidated statements of operations and requires that a company formally document, designate and assess the effectiveness of the transactions that receive hedge accounting treatment. Both at the inception of a hedge and on an ongoing basis, a hedge must be expected to be highly effective in achieving offsetting changes in cash flows or fair value attributable to the underlying risk being hedged. If the Company determines that a derivative instrument is no longer highly effective as a hedge, it discontinues hedge accounting prospectively and future changes in the fair value of the derivative are recognized in current earnings. The Company assesses hedge effectiveness at the end of each quarter. The Company does not offset derivative assets and liabilities within the consolidated balance sheets. In accordance with ASC 815, changes in the fair value of derivative instruments that are cash flow hedges are recognized in accumulated other comprehensive income (loss) and reclassified into earnings in the period in which the hedged item affects earnings. Derivative instruments that do not qualify, or cease to qualify, as hedges must be adjusted to fair value and the adjustments are recorded through net income (loss). The cash flows from derivative instruments receiving hedge accounting treatment are classified in the same categories as the hedged items in the consolidated statements of cash flows. |
Research and Development | Research and Development Research and development expenses are expensed as incurred and include wafers, masks, employee expenses, contractor fees, building costs, utilities and administrative expenses. |
Licensed Patents and Technologies | Licensed Patents and Technologies The Company has entered into a number of royalty agreements to license patents and technology used in the design of its products. The Company carries two types of royalties: lump-sum Lump-sum non-refundable Running royalties are paid based on the revenue of related products sold by the Company. |
Stock-Based Compensation | Stock-Based Compensation The Company follows the provisions of ASC 718, “Compensation-Stock Compensation” (“ASC 718”). Under ASC 718, stock-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense, net of the estimated forfeiture rate, over the requisite service period. As permitted under ASC 718, the Company elected to recognize compensation expense for all options with graded vesting based on the graded attribution method. The Company uses the Black-Scholes option-pricing model to measure the grant-date-fair-value of options. The Black-Scholes model requires certain assumptions to determine an option’s fair value, including expected |
Earnings per Share | Earnings Per Share In accordance with ASC 260, “Earnings Per Share”, the Company computes basic earnings per share by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect the dilution of potential common stock outstanding during the period including stock options and restricted stock units, using the treasury stock method (by using the average stock price for the period to determine the number of shares assumed to be purchased from the exercise of stock options and restricted stock units), and convertibles, using the if-converted |
Income Taxes | Income Taxes The Company accounts for income taxes in accordance with ASC 740, “Income Taxes” (“ASC 740”). ASC 740 requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in a company’s financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based upon the difference between the financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Income tax expense is the tax payable for the period and the change during the period in deferred tax assets and liabilities. Valuation allowances are established when it is necessary to reduce deferred tax assets to the amount expected to be realized. The evaluation of the recoverability of the deferred tax assets and the need for a valuation allowance requires management to weigh all positive and negative evidence to reach a conclusion that it is more likely than not that all or some portion of the deferred tax assets will not be realized. Realization of the future tax benefits related to the deferred tax assets is dependent on many factors, including historical operating results, expected timing of the reversals of existing temporary differences, the Company’s ability to generate future taxable income, and tax planning strategies. The Company recognizes and measures uncertain tax positions taken or expected to be taken in a tax return utilizing a two-step |
Concentration of Credit Risk | Concentration of Credit Risk The Company performs periodic credit evaluations of its customers’ financial condition and generally does not require collateral for customers on accounts receivable. The Company maintains reserves for potential credit losses, which are periodically reviewed. |
