Accounting Policies [Abstract] | |
Business, Basis of Presentation and Summary of Significant Accounting Policies | 1. Business, Basis of Presentation and Summary of Significant Accounting Policies Business MagnaChip Semiconductor Corporation (together with its subsidiaries, the “Company”) is a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products for consumer, computing, communication, industrial, automotive and Internet of Things (“IoT”) applications. The Company provides technology platforms for analog, mixed signal, power, high voltage, non-volatile memory and Radio Frequency (“RF”) applications. The Company’s business is comprised of two operating segments: Foundry Services Group and Standard Products Group. The Company’s Foundry Services Group provides specialty analog and mixed-signal foundry services mainly for fabless and Integrated Device Manufacturer (“IDM”) semiconductor companies that primarily serve the consumer, computing, communication, industrial, automotive and IoT applications. The Company’s Standard Products Group is comprised of two business lines: Display Solutions and Power Solutions. The Company’s Display Solutions products provide flat panel display solutions to major suppliers of large and small flat panel displays and include sensor products for mobile applications, and industrial applications and home appliances. The Company’s Power Solutions products include discrete and integrated circuit solutions for power management in consumer, communication 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 (“US GAAP”). Significant accounting policies followed by the Company in the preparation of the accompanying consolidated financial statements are summarized below. 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 US 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, intangible assets, 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 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. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. Foreign Currency Translation The Company has assessed in accordance with Accounting Standards Codification (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 exchange rates. Capital accounts are determined to be of a permanent nature and are therefore translated using historical exchange rates. Revenues and expenses are translated using average exchange rates for the respective periods. Foreign currency translation adjustments arising from differences in exchange rates from period to period are included in the foreign currency translation adjustment account in accumulated other comprehensive income (loss) of stockholders’ equity. Gains and losses due to transactions in currencies other than the functional currency are included as a component of other income, net in the statement 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 An allowance for doubtful accounts is provided based on the aggregate estimated uncollectability of the Company’s accounts receivable. 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. In addition, the Company also includes in accounts receivable, an allowance for additional products that may have to be provided, free of charge, to compensate customers for products that do not meet previously agreed yield criteria, the low yield compensation reserve. 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 constraints 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 market, using the average cost method, which approximates 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. Reserves are also established for excess inventory based on inventory levels in excess of six months of projected demand for each specific product. In addition, as prescribed in ASC 330, “Inventory,” the cost of inventories is determined based on the normal capacity of each 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. Vendor Rebates The Company, from time to time, entered into arrangements whereby rebates are obtained from vendors when the Company achieves certain levels of purchases. The vendor rebates are computed at an agreed upon amount or percentage of purchase levels. As these vendor rebates are impacted by actual and estimated purchases for the applicable agreed upon period, the Company periodically assess the progress of its purchase levels and revise the estimates when necessary. The Company accounts for such rebates as a reduction of inventory until the Company sells the product, at which time such rebates are reflected as a reduction of cost of sales in its consolidated statements of operations. Vendor rebates recorded as a reduction of inventory were $359 thousand as of December 31, 2016 and as a reduction of cost of sales were $4,044 thousand for the year ended December 31, 2016. 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. Restructuring Charges The Company recognizes restructuring charges in accordance with ASC 420, “Exit or Disposal Cost Obligations”. Certain costs and expenses related to exit or disposal activities are recorded as restructuring charges when liabilities for those costs and expenses are incurred. Lease Transactions The Company accounts for lease transactions as either operating leases or capital leases, depending on the terms of the underlying lease agreements. Machinery and equipment acquired under capital lease agreements are recorded at the lower of the present value of future minimum lease payments and estimated fair value of leased property and depreciated using the straight-line method over their estimated useful lives. In addition, the aggregate lease payments are recorded as capital lease obligations, net of unaccrued interest. Interest is amortized over the lease period using the effective interest rate method. Leases that do not qualify as capital leases are classified as operating leases, and the related rental payments are expensed on a straight-line basis over the shorter of the estimated useful lives of the leased property and the lease term. Intangible Assets Intangible assets other than intellectual property include technology and customer relationships which are amortized on a straight-line basis over periods ranging from one to five years. 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 US 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 and 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 is 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, 2016, 98% of all employees of the Company were eligible for severance benefits. Accrued severance benefits are 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 is recognized when there is persuasive evidence of an arrangement, the price to the buyer is fixed or determinable, delivery has occurred and collectability of the sales price is reasonably assured. Revenue from the sale of products is recognized when title and risk of loss transfers to the customer, which is generally when the product is shipped to or accepted by the customer depending on the terms of the arrangement. A portion of the Company’s sales are made through distributors for which revenue recognition criteria are usually met when the product is shipped to or accepted by the distributors, consistent with the principles described above. However, the risk of loss may not pass upon shipment of products to the distributor due to a variety of reasons, including the nature of the business arrangement with the distributor. For example, the financial condition of a distributor may indicate that payments by the distributor to the Company are contingent on resale of products to an end customer. In this situation, the Company defers recognition of revenue and cost of revenue on transactions with such distributor until the product has been resold to the end customer. The Company recorded deferred revenue in the amount of $11,092 thousand as of December 31, 2016 and $10,060 thousand as of December 31, 2015 as the Company received cash from certain customers and distributors for the sale of products prior to risk of loss being transferred based on the terms of the arrangement. In accordance with revenue recognition guidance, any tax assessed by a governmental authority that is directly imposed on a revenue-producing transaction between a seller and a customer is presented in the statements of operations on a net basis (excluded from revenues). The Company provides a warranty, under which customers can return defective products. The Company estimates the costs related to those defective product returns and records them as a component of cost of sales. In addition, the Company offers sales returns (other than those that relate to defective products under warranty), yield provisions, cash discounts for early payments and certain allowances to its customers, including distributors. The Company records reserves for those returns, discounts and allowances as a deduction from sales, based on historical experience and other quantitative and qualitative factors. 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 $1,631 thousand, $2,394 thousand, and $3,386 thousand for the years ended December 31, 2016, 2015 and 2014, respectively. 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. 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. Ineffective portions of a derivative instrument’s change in fair value are immediately recognized in 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. Advertising The Company expenses advertising costs as incurred. Advertising expense was approximately $149 thousand, $144 thousand and $155 thousand for the years ended December 31, 2016, 2015 and 2014, 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 liability include historical and anticipated rates of warranty claims and repair or replacement costs per claim to satisfy the Company’s warranty obligation. As these factors are impacted by actual experience and future expectations, the Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts when necessary. Research and Development Research and development costs 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 and running basis. Lump-sum royalties which require initial payments, usually paid in installments, represent a non-refundable commitment, such that the total present value of these payments is recorded as a prepaid expense and a liability upon execution of the agreements and the costs are amortized over the contract period using the straight-line method and charged to research and development expenses in the consolidated statements of operations. 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 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, expected volatility and fair value of underlying common share. 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. The expected volatility was estimated using historical volatility of share prices of similar public entities. 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. In determining the hypothetical shares repurchased, the Company uses the average share price for the period. In the case that earnings are negative, any potential common stock equivalents would have the effect of being anti-dilutive in the computation of net loss per share. 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 bases of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are established when it is necessary to reduce deferred tax assets to the amount expected to be realized. Income tax expense is the tax payable for the period and the change during the period in deferred tax assets and liabilities. The Company recognizes and measures uncertain tax positions taken or expected to be taken in a tax return utilizing a two-step process. In the first step, recognition, the Company determines whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The second step addresses measurement of a tax position that meets the more-likely-than-not criteria. The tax position is measured at the largest amount of benefit that has a likelihood of greater than 50 percent of being realized upon ultimate settlement. 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. Recent Accounting Pronouncements In August 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 reduces the existing diversity in practice in financial reporting across all industries by clarifying certain existing principles in ASC 230, Statement of Cash Flows, (“ASC 230”) including providing additional guidance on how and what an entity should consider in determining the classification of certain cash flows. In addition, in November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230), Restricted Cash (“ASU 2016-18”). ASU 2016-18 clarifies certain existing principles in ASC 230, including providing additional guidance related to transfers between cash and restricted cash and how entities present, in their statement of cash flows, the cash receipts and cash payments that directly affect the restricted cash accounts. These ASUs are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the adoption of ASU 2016-15 to have a material effect on the Company’s consolidated financial statements. The adoption of ASU 2016-18 will modify the Company’s current disclosures by reclassifying certain balances within the consolidated statement of cash flows, but this is not expected to have a material effect on the Company’s consolidated financial statements. In March 2016, the FASB issued Accounting Standards Update No. 2016-09, “Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 can be applied either on a retrospective or prospective basis and is effective for fiscal years beginning after December 15, 2016 and interim periods within those years. The Company will adopt ASU 2016-09 in the first quarter of 2017. The primary impact of adoption will be the recognition of excess tax benefits within income tax provision rather than within shareholders’ equity, which the Company will adopt on a prospective basis. As the Company does not have a significant amount of excess tax benefits from share-based payment transactions, it does not expect the adoption of ASU 2016-09 to have a material effect on its consolidated financial statements. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”) in order to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under US GAAP. ASU 2016-02 requires that a lessee should recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term on the balance sheet. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those reporting periods using a modified retrospective approach and early adoption is permitted. The Company is performing a preliminary review of its contracts that are expected to be applied under the new guidance. In November 2015, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update No. 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes” (“ASU 2015-17”). The amendments in ASU 2015-17 require an entity to classify all deferred tax assets and liabilities as noncurrent. ASU 2015-17 is effective for fiscal years beginning after December 15, 2016 and interim periods within those years. The Company will adopt ASU 2015-17 in the first quarter of 2017. As the Company does not have a significant balance of current deferred tax assets and liabilities, it believes that the implementation of this guidance will have no material impact on its consolidated financial statements. In July 2015, the FASB issued Accounting Standards Update No. 2015-11, “Simplifying the Measurement of Inventory” (“ASU 2015-11”). Under this ASU, inventory will be measured at the lower of cost and net realizable value, and options that currently exist for market value will be eliminated. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. No other changes were made to the current guidance on inventory measurement. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016 and interim periods within those years. The Company will adopt ASU 2015-11 in the first quarter of 2017 and believes that the implementation of this guidance will have no material impact on its consolidated financial statements. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”). ASU 2014-09 supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605)”, and requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016 (the “Original Effective Date”), including interim periods within that reporting period, and can be adopted either retrospectively to each prior period presented or as a cumulative-effect adjustment as of the date of adoption, with early application permitted as of the Original Effective Date. In August 2015, the FASB issued ASU 2015-14 “Deferral of the Effective Date,” which defers the required adoption date of ASU 2014-09 by one year. As a result of the deferred effective date, ASU 2014-09 will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. In March 2016, the FASB issued Accounting Standards Update No. 2016-08, “Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” (“ASU 2016-08”) clarifying the implementation guidance on principal versus agent considerations. Specifically, an entity is required to determine whether the nature of a promise is to provide the specified good or service itself (that is, the entity is a principal) or to arrange for the good or service to be provided to the customer by the other party (that is, the entity is an agent). The determination influences the timing and amount of revenue recognition. In May 2016, the FASB issued Accounting Standards Update No. 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients” (“ASU 2016-12”) clarifying how to assess collectibility, present sales tax, treat noncash consideration, and account for completed and modified contracts at the time of transition. In addition, ASU 2016-12 clarifies that an entity retrospectively applying the guidance in Topic 606 is not required to disclose the effect of the accounting change in the period of adoption. The effective date and transition requirements for ASU 2016-12, ASU 2016-08 and ASU 2014-09 ar |

Fair Value Measurements | 2. 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, 2016, 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) $ 453 $ 453 — $ 453 — As of December 31, 2015, 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) $ 40 $ 40 — $ 40 — Items not reflected in the table above include cash and cash equivalents, restricted cash, 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, with the exception of cash (Level 1). Fair Value of Long-term Borrowings December 31, 2016 December 31, 2015 Carrying Fair Carrying Fair (In thousands of US dollars) Long-term Borrowings: 6.625% senior notes due July 2021 (Level 2) $ 221,082 $ 193,500 $ 220,375 $ 157,500 On July 18, 2013, the Company issued 6.625% senior notes due July 15, 2021 (the “2021 Notes”) of $225.0 million, which represents the principal amount, excluding $1.1 million of original issue discount and $5.1 million of debt issuance costs. The Company estimates the fair value of the 2021 Notes using the market approach, which utilizes quoted market prices that fall under Level 2. For further description of the 2021 Notes, see Note 10, “Long-term Borrowings”. Fair Values Measured on a Non-recurring Basis The Company’s non-financial assets, such as property, plant and equipment, and intangible assets are recorded at fair value upon acquisition and are remeasured at fair value only if an impairment charge is recognized. As of December 31, 2016 and 2015, the Company did not have any assets or liabilities measured at fair value on a non-recurring basis. |

Derivative Financial Instruments | 8. Derivative Financial Instruments The Company’s Korean subsidiary from time to time has entered into zero cost collar contracts to hedge the risk of changes in the functional-currency-equivalent cash flows attributable to currency rate changes on U.S. dollar denominated revenues. Details of derivative contracts as of December 31, 2016 are as follows (in thousands): Date of transaction Type of derivative Total notional amount Month of settlement November 11, 2016 Zero cost collar $ 18,000 March to August 2017 Details of derivative contracts as of December 31, 2015 are as follows (in thousands): Date of transaction Type of derivative Total notional amount Month of settlement September 30, 2015 Zero cost collar $ 30,000 January to March 2016 September 30, 2015 Zero cost collar $ 30,000 April to June 2016 The zero cost collar contracts qualify as cash flow hedges under ASC 815, “Derivatives and Hedging,” since at both the inception of the contracts and on an ongoing basis, the hedging relationship was and is expected to be highly effective in achieving offsetting cash flows attributable to the hedged risk during the term of the contracts. The Company is utilizing the “hypothetical derivative” method to measure the effectiveness by comparing the changes in value of the actual derivative versus the change in fair value of the “hypothetical derivative.” The fair values of the Company’s outstanding zero cost collar contracts recorded as liabilities as of December 31, 2016 and 2015 are as follows (in thousands): Derivatives designated as hedging instruments: December 31, 2016 2015 Liability Derivatives: Zero cost collars Other current liabilities $ 453 $ 40 Offsetting of derivative liabilities as of December 31, 2016 is as follows (in thousands): As of December 31, 2016 Gross amounts of Gross amounts Net amounts of Gross amounts not offset Net amount Financial Cash collateral Liability Derivatives: Zero cost collars $ 453 $ — $ 453 $ — $ (650 ) $ (197 ) Offsetting of derivative liabilities as of December 31, 2015 is as follows (in thousands): As of December 31, 2015 Gross amounts of Gross amounts Net amounts of Gross amounts not offset Net amount Financial Cash collateral Liability Derivatives: Zero cost collars $ 40 $ — $ 40 $ — $ — $ 40 For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of accumulated other comprehensive income (“AOCI”) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative, representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness, are recognized in current earnings. The following table summarizes the impact of derivative instruments on the consolidated statement of operations for the years ended December 31, 2016 and 2015 (in thousands): Derivatives in ASC 815 Cash Flow Hedging Relationships Amount of Location of Amount of Location of Amount of 2016 2015 2016 2015 2016 2015 Zero cost collars $ (1,032 ) $ (3,748 ) Net sales $ (637 ) $ (3,222 ) Other income, $ (272 ) $ (516 ) As of December 31, 2016, the amount expected to be reclassified from accumulated other comprehensive income into loss within the next twelve months is $436 thousand. The Company set aside $2,500 thousand and $6,000 thousand of cash deposits to the counterparty, Nomura Financial Investment (Korea) Co., Ltd. (“NFIK”) as required for the zero cost collar contracts outstanding as of December 31, 2016 and 2015, respectively. These cash deposits are recorded as hedge collateral on the consolidated balance sheets. The Company is required to deposit additional cash collateral with NFIK for any exposure in excess of $500 thousand, and $650 thousand was required as of December 31, 2016 and recorded as hedge collateral on the consolidated balance sheets. There was no such cash collateral required as of December 31, 2015. These outstanding zero cost collar contracts are subject to termination if the sum of qualified and unrestricted cash and cash equivalents held by the Company is less than $30,000 thousand on the last day of a fiscal quarter. |

Equity Incentive Plans | 13. Equity Incentive Plans The Company adopted its 2009 Common Unit Plan, or the 2009 Plan, effective December 8, 2009, which is administered by the Compensation Committee of the Company’s Board of Directors (the “Compensation Committee”). The 2009 Plan terminated in connection with the Company’s initial public offering in March 2011, and no additional options or other equity awards may be granted under the 2009 Plan. However, options granted under the 2009 Plan prior to its termination will remain outstanding until they are either exercised or expire. The Company adopted its 2011 Equity Incentive Plan, or the 2011 Plan, in March 2010. The Company amended and restated the 2011 Plan in February 2011, and the Company’s stockholders approved the amendment in March 2011 to reflect that it became effective in 2011 in connection with the Company’s initial public offering in March 2011. Awards may be granted under the 2011 Plan to the Company’s employees, officers, directors, or consultants or those of any present or future parent or subsidiary corporation or other affiliated entity. While the Company may grant incentive stock options only to employees, the Company may grant nonstatutory stock options, stock appreciation rights, restricted stock purchase rights or bonuses, restricted stock units, performance shares, performance units and cash-based awards or other stock-based awards to any eligible participant, subject to terms and conditions determined by the Compensation Committee. The term of options shall not exceed ten years from the date of grant. Restricted stock purchase rights shall be exercisable within a period established by the Compensation Committee, which shall in no event exceed thirty days from the effective date of the grant. As of December 31, 2016, an aggregate maximum of 7,274 thousand shares were authorized and 557 thousand shares were reserved for all future grants. Stock options and stock appreciation rights must have exercise prices at least equal to the fair market value of the stock at the time of their grant pursuant to the 2011 Plan. The requisite service period, or the period during which a grantee is required to provide service in exchange for option grants, coincides with the vesting period. Stock options typically vest over three years following grant. Restricted stock units granted under the 2011 Plan represent a right to receive shares of the Company’s common stock when the restricted stock unit vests. No monetary payment (other than applicable tax withholding) shall be required as a condition of receiving shares pursuant to a restricted stock unit, the consideration for which shall be services actually rendered to a participating company or for its benefit. Stock issued pursuant to any restricted stock unit may (but need not) be made subject to vesting conditions based upon the satisfaction of such service requirements, conditions, restrictions or performance criteria as shall be established by the Compensation Committee and set forth in the award agreement evidencing such award. Restricted stock units typically vest over three years following grant. The purchase price for shares issuable under each restricted stock purchase right shall be established by the Compensation Committee in its discretion. No monetary payment (other than applicable tax withholding) shall be required as a condition of receiving shares pursuant to a restricted stock bonus, the consideration for which shall be services actually rendered to a participating company or for its benefit. Stock issued pursuant to any restricted stock award may (but need not) be made subject to vesting conditions based upon the satisfaction of such service requirements, conditions, restrictions or performance criteria as shall be established by the Compensation Committee and set forth in the award agreement evidencing such award. During any period in which stock acquired pursuant to a restricted stock award remain subject to vesting conditions, such stock may not be sold, exchanged, transferred, pledged, assigned or otherwise disposed of other than pursuant to an ownership change event or transfer by will or the laws of descent and distribution. The grantee shall have all of the rights of a stockholder of the Company holding stock, including the right to vote such stock and to receive all dividends and other distributions paid with respect to such stock; provided, however, that if so determined by the Compensation Committee and provided by the award agreement, such dividends and distributions shall be subject to the same vesting conditions as the stock subject to the restricted stock award with respect to which such dividends or distributions were paid. If a grantee’s service terminates for any reason, whether voluntary or involuntary (including the grantee’s death or disability), then (a) the Company (or its assignee) has the option to repurchase for the purchase price paid by the grantee any stock acquired by the grantee pursuant to a restricted stock purchase right which remain subject to vesting conditions as of the date of the grantee’s termination of service and (b) the grantee shall forfeit to the Company any stock acquired by the grantee pursuant to a restricted stock bonus which remain subject to vesting conditions as of the date of the grantee’s termination of service. The Company has the right to assign at any time any repurchase right it may have, whether or not such right is then exercisable, to one or more persons as may be selected by the Company. The following summarizes restricted stock unit activities for the year ended December 31, 2016 and 2015. For the year ended December 31, 2014, there were no restricted stock unit activities.

Foreign Currency Gain (Loss), Net | 15. Foreign Currency Gain (Loss), Net Net foreign currency gain or loss includes non-cash translation gain or loss associated with intercompany balances. A substantial portion of the Company’s net foreign currency gain or loss is non-cash translation gain or loss associated with intercompany long-term loans to our Korean subsidiary. The loans are denominated in U.S. dollars and are affected by changes in the exchange rate between the Korean won and the U.S. dollar. As of December 31, 2016, 2015 and 2014, the outstanding intercompany loan balances including accrued interest between the Korean subsidiary and the Dutch subsidiary were $598,212 thousand, $591,388 thousand and $765,265 thousand, respectively. The Korean won to U.S. dollar exchange rates were 1,208.5:1, 1,172.0:1 and 1,099.2:1 using the first base rate as of December 31, 2016, 2015 and 2014, respectively, as quoted by the KEB Hana Bank. |

Income Taxes | 16. Income Taxes The Company’s income tax expenses are composed of domestic and foreign income taxes depending on the relevant tax jurisdictions. Domestic income (loss) before taxes and income tax expenses are generated or incurred in the United States, where the parent company resides. The components of income tax expense are as follows (in thousands): Year Ended December 31, 2016 2015 2014 Income (loss) before income taxes Domestic $ (1,738 ) $ 32,903 $ (22,146 ) Foreign (24,133 ) (132,857 ) (93,563 ) $ (25,871 ) $ (99,954 ) $ (115,709 ) Current income taxes expense (benefit) Domestic $ (6 ) $ 25 $ (3,300 ) Foreign 3,386 (14,301 ) 3,312 Uncertain tax position liability (Domestic) 12 10 10 Uncertain tax position liability (Foreign) 339 (1,220 ) (66 ) 3,731 (15,486 ) (44 ) Deferred income taxes expense (benefit) Foreign 13 399 1,567 Total income tax expense (benefit) $ 3,744 $ (15,087 ) $ 1,523 Effective tax rate (14.5 )% 15.1 % (1.3 )% The differences between the annual effective tax rates and the U.S. federal statutory rate of 35.0% primarily result from the non-income based withholding tax attributable to intercompany interest income of the Company’s Dutch subsidiary, application of lower tax rates associated with certain earnings from the Company’s operations outside the U.S., the parent Company’s interest income, which is non-taxable for US tax purposes and the change of deferred tax assets and valuation allowance. The significant increase in income tax expense in 2016 is related to the reversal of withholding tax payable with respect to the waiver of the accrued interest on the loans granted to our Korean subsidiary by our Dutch subsidiary in 2015. Korean and Dutch subsidiaries agreed that our Dutch subsidiary waives and releases a partial amount of unpaid interest of $174 million on its intercompany loans granted to our Korean subsidiary in order to decrease the cumulative losses of our Korean subsidiary to enhance the subsidiary’s credit standing under the local banking rules. This transaction created a taxable income for our Korean subsidiary but did not result in a liability because of the utilization of expired loss carryforwards, which is deductible only against gains from cancellation of debt. The loss was not tax deductible for our Dutch subsidiary. This transaction also resulted in taxable loss for our Luxemburg subsidiary and this tax benefit was offset by an increase in the change in valuation allowance. In connection with the waiver of unpaid interest, the related withholding tax was reversed, resulting in the recognition of income tax benefit of $17.8 million as of December 31, 2015. The statutory income tax rate of the Company’s Korean subsidiary was approximately 24.2% in 2016, 2015 and 2014. The provision for domestic and foreign income taxes incurred is different from the amount calculated by applying the statutory tax rate to the net income before income taxes. The significant items causing this difference are as follows (in thousands): Year Ended December 31, 2016 2015 2014 Provision computed at statutory rate $ (9,055 ) $ (34,984 ) $ (40,498 ) Difference in foreign tax rates 1,995 24,359 10,130 Permanent differences Derivative assets adjustment (149 ) (143 ) (1,526 ) TPECs, hybrid and other interest (10,353 ) (27,273 ) (6,813 ) Permanent impairment — (62,334 ) — Thin capitalization 2,120 2,457 — Permanent foreign currency gain (loss) (54 ) 11,575 (901 ) Penalty 689 — — Non-deductible settlement — — 6,318 Non-deductible bad debt expense — 89 — Other permanent differences 50 (69 ) (1,097 ) Withholding tax 3,092 (14,457 ) 3,506 Foreign exchange rate adjustment (1,838 ) (8,954 ) 4,687 Change in valuation allowance 10,095 95,757 29,484 Tax credits claimed (706 ) (875 ) (1,811 ) Tax credits expired 1,578 — — Uncertain tax positions liability 351 (1,211 ) (56 ) Others 5,929 976 100 Income tax expense (benefit) $ 3,744 $ (15,087 ) $ 1,523 The permanent differences above include non-taxable TPECs and interest income from other financial instruments for US tax purposes and non-deductible interest expense according to the thin capitalization rule for Korean tax purposes. The permanent impairment of $62,334 thousand in 2015 was related to the loss recognized by the Company’s Luxemburg subsidiary in connection with the cancellation of debt as described above, which was not recognized for US tax purposes. A summary of the composition of net deferred income tax assets (liabilities) as of December 31, 2016, 2015 and 2014 are as follows (in thousands): Year-Ended December 31, 2016 2015 2014 Deferred tax assets Accounts receivables $ — $ — $ 1,076 Inventories 1,822 4,063 11,015 Derivative assets 110 10 — Accrued expenses 2,803 12,939 9,030 Product warranties 113 345 719 Other reserves 372 474 457 Royalty income — — 147 Property, plant and equipment 13,314 13,986 15,914 Intangible assets 103 407 780 Accumulated severance benefits 31,478 31,038 30,413 Foreign currency translation losses 53,130 52,294 17,496 NOL carry-forwards 167,590 155,545 80,979 Tax credit 20,249 21,868 25,161 Other long-term payable 2,079 2,385 1,034 Others 4,885 1,974 1,990 Total deferred tax assets 298,048 297,328 196,211 Less: Valuation allowance (281,473 ) (279,867 ) (194,739 ) 16,575 17,461 1,472 Deferred tax liabilities Foreign currency translation gains 14,338 14,859 748 Prepaid expense 1,644 1,953 — Others 410 478 147 Total deferred tax liabilities 16,392 17,290 895 Net deferred tax assets $ 183 $ 171 $ 577 Reported as Current deferred income tax assets $ 37 $ 34 $ 237 Non-current deferred income tax assets $ 193 $ 238 $ 415 Current deferred income tax liabilities $ (46 ) $ (98 ) $ (72 ) Non-current deferred income tax liabilities $ (1 ) $ (3 ) $ (3 ) The valuation allowances at December 31, 2016, 2015 and 2014 are primarily attributable to deferred tax assets for the uncertainty in taxable income at the Company’s Korean subsidiary. The Company has recorded a full valuation allowance against the deferred tax assets, net of its deferred tax liabilities, and against certain foreign subsidiary’s deferred tax assets pertaining to its related tax loss carry-forwards that are not anticipated to generate a tax benefit. Changes in valuation allowance for deferred tax assets for the years ended December 31, 2016, 2015 and 2014 are as follows (in thousands): Year Ended December 31, 2016 2015 2014 Beginning balance $ 279,867 $ 194,739 $ 178,729 Charged to expense 10,095 95,757 29,484 NOL/tax credit claimed/expired (872 ) (1,197 ) (7,605 ) Translation adjustments (7,617 ) (9,432 ) (5,869 ) Ending balance $ 281,473 $ 279,867 $ 194,739 The amount presented as “Charged to expense” primarily relates to the utilization of net operating loss and tax credit carry-forwards, or pre-tax losses for which there is no tax benefit. The evaluation of the recoverability of the deferred tax asset and the need for a valuation allowance requires the Company 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 asset will not be realized. The weight given to the evidence is commensurate with the extent to which it can be objectively verified. The more negative evidence that exists, the more positive evidence is necessary and the more difficult it is to support a conclusion that a valuation allowance is not needed. Realization of the future tax benefits related to the deferred tax assets is dependent on many factors, including the Company’s ability to generate future taxable income within the period during which the temporary differences reverse, the outlook for the economic environment in which the Company operates and the overall future industry outlook. As of December 31, 2016, 2015 and 2014, the Company had net deferred tax assets of $183 thousand, $171 thousand and $577 thousand, respectively, related to the Company’s Japanese subsidiary. As of December 31, 2016, 2015 and 2014, the Company recorded a valuation allowance of $281,473 thousand, $279,867 thousand and $194,739 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 recorded these valuation allowances on deferred tax assets based on its assessment that the negative evidence of expected losses in early future years outweighs the positive evidence of historical income. As of December 31, 2016, the Company had approximately $684,851 thousand of net operating loss carry-forwards available to offset future taxable income, of which $280,417 thousand is associated with the Company’s Korean subsidiary, which expires in part at various dates through 2026. The net operating loss of $268,959 thousand associated with the Company’s Luxembourg subsidiary is mainly attributable to certain expenses incurred in connection with its shareholding in the Company’s Dutch subsidiary. Although this net operating loss amount is the carried forward indefinitely, it will be recaptured on future capital gain. The remaining net operating loss mainly relates to the US parent company and its domestic subsidiary, which expires in part at various dates through 2036. The Company utilized net operating loss of $279 thousand, $121 thousand and $1,219 thousand, for the years ended December 31, 2016, 2015 and 2014, respectively. The Company also has Korean, Dutch and U.S. tax credit carry-forwards of approximately $6,738 thousand, $13,121 thousand and $390 thousand, respectively, as of December 31, 2016. The Korean tax credits expire at various dates starting from 2017 to 2021, and 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, the U.S. and in various other jurisdictions. The Company is subject to income tax examinations by tax authorities of these jurisdictions for all open tax years. As of December 31, 2016, 2015 and 2014, the Company recorded $2,459 thousand, $2,139 thousand and $3,491 thousand of liabilities for unrecognized tax benefits, respectively. For the years ended December 31, 2016, 2015and 2014, the Company recorded $670 thousand, $1,606 thousand and $110 thousand of income tax benefits, respectively, by reversing liabilities due to the lapse of the applicable statute of limitations and incurred $687 thousand, $351 thousand and $44 thousand of income tax expenses, respectively, for uncertain tax positions mainly resulting from imputed interest related to intercompany balances. For the years ended December 31, 2016, 2015 and 2014, the Company recognized $334 thousand, $45 thousand, $10 thousand of interest and penalties, respectively, related to unrecognized tax benefits as a component of income tax expense. Total interest and penalties accrued as of December 31, 2016, 2015 and 2014 were $691 thousand, $359 thousand and $480 thousand, respectively. The Company is currently unaware of any uncertain tax positions that could result in significant additional payments, accruals, or other material deviation in this estimate over the next 12 months. 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, 2016 2015 2014 Unrecognized tax benefits, balance at the beginning $ 13,330 $ 14,969 $ 11,865 Additions based on tax positions related to the current year 942 1,789 4,472 Additions for tax positions of prior years 317 — 47 Lapse of statute of limitations (2,380 ) (2,142 ) (1,040 ) Translation adjustments (315 ) (1,287 ) (375 ) Unrecognized tax benefits, balance at the ending $ 11,894 $ 13,330 $ 14,969 |

Segment Reporting [Abstract] | |
Geographic and Segment Information | 17. Geographic and Segment Information The Company had previously reported its results of operations under one operating segment. During the second quarter of 2015, organizational changes were made to (i) realign the Company’s businesses and organizational structure and (ii) streamline and consolidate certain business processes to achieve greater operating efficiencies. In furtherance of these objectives, the Company combined its Display Solutions and Power Solutions business lines into a new segment called Standard Products Group. Beginning in the second quarter of 2015, the Company began reporting its financial results in two operating segments: Semiconductor Manufacturing Services and Standard Products Group. During the third quarter of 2015, the Company changed the name of its Semiconductor Manufacturing Services segment to Foundry Services Group. The Company’s chief operating decision maker is its Chief Executive Officer who allocates resources and assesses performance of the business and other activities based on gross profit. The two newly established operating segments were managed prospectively and all prior period amounts related to the segment change have been retrospectively reclassified to conform to the new presentation. The following sets forth information relating to the operating segments (in thousands): Year Ended December 31, 2016 2015 2014 Net Sales Foundry Services Group $ 273,961 $ 290,775 $ 360,549 Standard Products Group Display Solutions 281,967 207,480 199,861 Power Solutions 131,468 134,814 137,246 Total Standard Products Group 413,435 342,294 337,107 All other 573 643 562 Total net sales $ 687,969 $ 633,712 $ 698,218 Year Ended December 31, 2016 2015 2014 Gross Profit Foundry Services Group $ 69,412 $ 66,175 $ 75,739 Standard Products Group 87,194 68,094 76,561 All other (380 ) 595 562 Total gross profit $ 156,226 $ 134,864 $ 152,862 The following is a summary of net sales by geographic region, based on the location to which the products are billed (in thousands): Year Ended December 31, 2016 2015 2014 Korea $ 219,618 $ 241,715 $ 260,139 Asia Pacific (other than Korea) 391,875 316,562 324,248 U.S.A. 33,201 51,164 91,308 Europe 42,274 23,461 21,159 Others 1,001 810 1,364 Total $ 687,969 $ 633,712 $ 698,218 Net sales from the Company’s top ten largest customers accounted for 64%, 64% and 61% for the years ended December 31, 2016, 2015 and 2014, respectively.

Commitments and Contingencies | 18. Commitments and Contingencies Operating Agreements with SK Hynix In connection with the acquisition of the non-memory semiconductor business from SK Hynix on October 4, 2004 (the “Original Acquisition”), the Company entered into several agreements with SK Hynix, including a non-exclusive cross license that provides the Company with access to certain of SK Hynix’s intellectual property for use in the manufacture and sale of non-memory semiconductor products. The Company also agreed to provide certain utilities and infrastructure support services to SK Hynix. Upon the closing of the Original Acquisition, the Company’s Korean subsidiary and SK Hynix also entered into lease agreements under which the Company’s Korean subsidiary leases space to SK Hynix in several buildings, primarily warehouses and utility facilities, in Cheongju, Korea. These leases are generally for an initial term of 20 years plus an indefinite number of renewal terms of 10 years each. Each of the leases is cancelable upon 90 days’ notice by the lessee. The Company also leases certain land from SK Hynix located in Cheongju, Korea. The term of this lease is indefinite unless otherwise agreed by the parties, and as long as the buildings remain on the lease site and are owned and used by the Company for permitted uses. Operating Leases The Company leases land, office space and equipment under various operating lease agreements with various terms. Rental expenses were approximately $8,898 thousand, $8,194 thousand and $9,421 thousand for the years ended December 31, 2016, 2015 and 2014, respectively. As of December 31, 2016, the minimum aggregate rental payments due under non-cancelable lease contracts are as follows (in thousands): 2017 $ 4,781 2018 2,786 2019 2,279 2020 2,200 2021 1,844 2022 and thereafter 23,547 $ 37,437 Securities Class Action Complaints The Company recorded the $23,500 thousand of the settlement obligation for the Class Action Litigation as accrued expenses in the consolidated balance sheets as of December 31, 2015 and as selling, general and administrative expenses in the consolidated statements of operations for the year ended December 31, 2015. For further information regarding the Class Action Litigation, see “Item 3. Legal Proceedings” included elsewhere in this Report. The Company recorded $29,571 thousand of the proceeds from the insurers as other receivables in the consolidated balance sheets as of December 31, 2015 and as a deduction of the selling, general and administrative expenses in the consolidated statements of operations for the year ended December 31, 2015. The proceeds from the insurers of $29,571 thousand were deposited into the Company’s escrow account during the first quarter of 2016 and the Company reclassified the $29,571 thousand deposits recorded in other receivables into restricted cash. During the third quarter of 2016, the Company disbursed the aggregate settlement payment of $23,500 thousand after the court granted plaintiffs’ renewed motion for preliminary approval of the settlement in July 2016. Upon the settlement payment, $6,114 thousand of the insurance proceeds remained in the Company’s escrow account. For subsequent treatment of the escrow amount, see “ Shareholder Derivative Complaints SEC Enforcement Staff Review In March 2014, the Company voluntarily reported to the SEC that the Company’s Audit Committee (the “Audit Committee”) had determined that the Company incorrectly recognized revenue on certain transactions and as a result would restate its financial statements, and that the Audit Committee had commenced an independent investigation. Over the course of 2014 and the first two quarters of 2015, the Company voluntarily produced documents to the SEC regarding the various accounting issues identified during the independent investigation, and whether the Company’s hiring of an accountant from the Company’s independent registered public accounting firm impacted that accounting firm’s independence. On July 22, 2014, the Staff of the SEC’s Division of Enforcement obtained a Formal Order of Investigation. On March 12, 2015, the SEC issued a subpoena for documents to the Company in connection with its investigation. The Company will continue to cooperate with the SEC in this investigation, and has produced documents in response to the subpoena. At this time, the Company is unable to estimate any reasonably possible loss, or range of reasonably possible losses, with respect to the matters described above. Shareholder Derivative Complaints The settlement for the shareholder derivative actions described in “Item 3. Legal Proceedings” provided for an aggregate payment from the Company defendants’ directors and officers insurance policies of $3,000 thousand to be made to an escrow account, which will be payable to the Company (less certain deductions and applicable interest) once the settlement becomes effective. For further information regarding the shareholder derivative actions, see “Item 3. Legal Proceedings” included elsewhere in this Report. The $3,000 thousand settlement payment was included in the insurance proceeds of $29,571 thousand as discussed in “ Securities Class Action Complaints On June 10, 2016, the court granted plaintiffs’ motion for preliminary approval of the proposed settlement. On October 18, 2016, after a hearing held on October 14, 2016, the court entered its order and final judgment (the “Judgment”) granting final approval of the proposed settlement and awarding plaintiffs’ counsel $750 thousand for attorneys’ fees and litigation expenses. As a result, $750 thousand was paid out of the Company’s escrow account. The Judgment was not appealed within the applicable appeals period (on or before December 19, 2016). The settlement therefore became effective after the expiration of the appeals period and $2,258 thousand was paid to the Company from the escrow account, previously recorded as restricted cash, in December 2016. The remaining restricted cash related to insurance proceeds of $3,078 thousand was also released in December 2016. |

The Company amended the Rights Agreement on March 2, 2016 and September 2, 2016. As amended, each Right, once exercisable, will entitle the registered holder to purchase from the Company one one-thousandth of a share of Series A Junior Participating Preferred Stock, par value $0.01 per share, at a purchase price of $12, subject to adjustment (the “Purchase Price”). The Rights are not presently exercisable and remain attached to the shares of common stock unless and until the occurrence of the earlier of the following (the “Distribution Date”): (i) the tenth day after the public announcement or disclosure by the Company or any person or group of affiliated or associated persons that any person or group of affiliated or associated persons has become an “Acquiring Person” by obtaining beneficial ownership of 12.5% (or 20% in the case of a “passive institutional investor,” which is defined generally as any person who has reported beneficial ownership of shares of common stock on Schedule 13G under the Securities Exchange Act of 1934) or more of the Company’s outstanding common stock, subject to certain exceptions; or (ii) the tenth business day (or such later date as the Company’s Board of Directors may designate before a person or group of affiliated or associated persons becomes an Acquiring Person) after the commencement of, or first public announcement of the intent of any person to commence, a tender or exchange offer by any person or group of affiliated or associated persons, which would, if consummated, result in such person or group becoming an Acquiring Person. The Board of Directors may redeem all of the Rights for $0.001 per Right at any time before any person or group of affiliated or associated persons becomes an Acquiring Person. In addition, at any time on or after any person or group of affiliated or associated persons becomes an Acquiring Person (but before any person or group of affiliated or associated persons becomes the owner of 50% or more of the Company’s outstanding common stock), the Board of Directors may exchange all or part of the Rights (other than the Rights beneficially owned by the Acquiring Person and certain affiliated persons) for shares of common stock at an exchange ratio of one share of common stock per Right. The Rights will expire at the close of business on March 5, 2017, unless redeemed or exchanged prior to that time. If any person or group of affiliated or associated persons becomes an Acquiring Person, then, after the Distribution Date, each Right (other than Rights beneficially owned by the Acquiring Person and certain affiliated persons or transferees thereof) will entitle the holder to purchase, for the Purchase Price, a number of shares of common stock having a market value of twice the Purchase Price. Alternatively, if, after any person or group of affiliated or associated persons becomes an Acquiring Person, (1) the Company is involved in a merger or other business combination in which the Company is not the surviving corporation or its common stock is changed into or exchanged for other securities or assets; or (2) the Company or one or more of its subsidiaries sell or otherwise transfer assets or earning power aggregating more than 50% of the assets or earning power of the Company and its subsidiaries, taken as a whole, then each Right will entitle the holder to purchase, for the Purchase Price, a number of shares of common stock of the other party to such business combination or sale (or in certain circumstances, an affiliate) having a market value of twice the Purchase Price. |

Accounting Policies [Abstract] | |
Business | Business MagnaChip Semiconductor Corporation (together with its subsidiaries, the “Company”) is a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products for consumer, computing, communication, industrial, automotive and Internet of Things (“IoT”) applications. The Company provides technology platforms for analog, mixed signal, power, high voltage, non-volatile memory and Radio Frequency (“RF”) applications. The Company’s business is comprised of two operating segments: Foundry Services Group and Standard Products Group. The Company’s Foundry Services Group provides specialty analog and mixed-signal foundry services mainly for fabless and Integrated Device Manufacturer (“IDM”) semiconductor companies that primarily serve the consumer, computing, communication, industrial, automotive and IoT applications. The Company’s Standard Products Group is comprised of two business lines: Display Solutions and Power Solutions. The Company’s Display Solutions products provide flat panel display solutions to major suppliers of large and small flat panel displays and include sensor products for mobile applications, and industrial applications and home appliances. The Company’s Power Solutions products include discrete and integrated circuit solutions for power management in consumer, communication 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 (“US GAAP”). Significant accounting policies followed by the Company in the preparation of the accompanying consolidated financial statements are summarized below. |
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 US 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, intangible assets, 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 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. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. |
Foreign Currency Translation | Foreign Currency Translation The Company has assessed in accordance with Accounting Standards Codification (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 exchange rates. Capital accounts are determined to be of a permanent nature and are therefore translated using historical exchange rates. Revenues and expenses are translated using average exchange rates for the respective periods. Foreign currency translation adjustments arising from differences in exchange rates from period to period are included in the foreign currency translation adjustment account in accumulated other comprehensive income (loss) of stockholders’ equity. Gains and losses due to transactions in currencies other than the functional currency are included as a component of other income, net in the statement 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 An allowance for doubtful accounts is provided based on the aggregate estimated uncollectability of the Company’s accounts receivable. 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. In addition, the Company also includes in accounts receivable, an allowance for additional products that may have to be provided, free of charge, to compensate customers for products that do not meet previously agreed yield criteria, the low yield compensation reserve. |
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 constraints 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 market, using the average cost method, which approximates 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. Reserves are also established for excess inventory based on inventory levels in excess of six months of projected demand for each specific product. In addition, as prescribed in ASC 330, “Inventory,” the cost of inventories is determined based on the normal capacity of each 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. |
Vendor Rebates | Vendor Rebates The Company, from time to time, entered into arrangements whereby rebates are obtained from vendors when the Company achieves certain levels of purchases. The vendor rebates are computed at an agreed upon amount or percentage of purchase levels. As these vendor rebates are impacted by actual and estimated purchases for the applicable agreed upon period, the Company periodically assess the progress of its purchase levels and revise the estimates when necessary. The Company accounts for such rebates as a reduction of inventory until the Company sells the product, at which time such rebates are reflected as a reduction of cost of sales in its consolidated statements of operations. Vendor rebates recorded as a reduction of inventory were $359 thousand as of December 31, 2016 and as a reduction of cost of sales were $4,044 thousand for the year ended December 31, 2016. |
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. |
Restructuring Charges | Restructuring Charges The Company recognizes restructuring charges in accordance with ASC 420, “Exit or Disposal Cost Obligations”. Certain costs and expenses related to exit or disposal activities are recorded as restructuring charges when liabilities for those costs and expenses are incurred. |
Lease Transactions | Lease Transactions The Company accounts for lease transactions as either operating leases or capital leases, depending on the terms of the underlying lease agreements. Machinery and equipment acquired under capital lease agreements are recorded at the lower of the present value of future minimum lease payments and estimated fair value of leased property and depreciated using the straight-line method over their estimated useful lives. In addition, the aggregate lease payments are recorded as capital lease obligations, net of unaccrued interest. Interest is amortized over the lease period using the effective interest rate method. Leases that do not qualify as capital leases are classified as operating leases, and the related rental payments are expensed on a straight-line basis over the shorter of the estimated useful lives of the leased property and the lease term. |
Intangible Assets | Intangible Assets Intangible assets other than intellectual property include technology and customer relationships which are amortized on a straight-line basis over periods ranging from one to five years. 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 US 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 and 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 is 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, 2016, 98% of all employees of the Company were eligible for severance benefits. Accrued severance benefits are 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 Revenue is recognized when there is persuasive evidence of an arrangement, the price to the buyer is fixed or determinable, delivery has occurred and collectability of the sales price is reasonably assured. Revenue from the sale of products is recognized when title and risk of loss transfers to the customer, which is generally when the product is shipped to or accepted by the customer depending on the terms of the arrangement. A portion of the Company’s sales are made through distributors for which revenue recognition criteria are usually met when the product is shipped to or accepted by the distributors, consistent with the principles described above. However, the risk of loss may not pass upon shipment of products to the distributor due to a variety of reasons, including the nature of the business arrangement with the distributor. For example, the financial condition of a distributor may indicate that payments by the distributor to the Company are contingent on resale of products to an end customer. In this situation, the Company defers recognition of revenue and cost of revenue on transactions with such distributor until the product has been resold to the end customer. The Company recorded deferred revenue in the amount of $11,092 thousand as of December 31, 2016 and $10,060 thousand as of December 31, 2015 as the Company received cash from certain customers and distributors for the sale of products prior to risk of loss being transferred based on the terms of the arrangement. In accordance with revenue recognition guidance, any tax assessed by a governmental authority that is directly imposed on a revenue-producing transaction between a seller and a customer is presented in the statements of operations on a net basis (excluded from revenues). The Company provides a warranty, under which customers can return defective products. The Company estimates the costs related to those defective product returns and records them as a component of cost of sales. In addition, the Company offers sales returns (other than those that relate to defective products under warranty), yield provisions, cash discounts for early payments and certain allowances to its customers, including distributors. The Company records reserves for those returns, discounts and allowances as a deduction from sales, based on historical experience and other quantitative and qualitative factors. 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 $1,631 thousand, $2,394 thousand, and $3,386 thousand for the years ended December 31, 2016, 2015 and 2014, respectively. |
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. 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. Ineffective portions of a derivative instrument’s change in fair value are immediately recognized in 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. |
Advertising | Advertising The Company expenses advertising costs as incurred. Advertising expense was approximately $149 thousand, $144 thousand and $155 thousand for the years ended December 31, 2016, 2015 and 2014, 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 liability include historical and anticipated rates of warranty claims and repair or replacement costs per claim to satisfy the Company’s warranty obligation. As these factors are impacted by actual experience and future expectations, the Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts when necessary. |
Research and Development | Research and Development Research and development costs 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 and running basis. Lump-sum royalties which require initial payments, usually paid in installments, represent a non-refundable commitment, such that the total present value of these payments is recorded as a prepaid expense and a liability upon execution of the agreements and the costs are amortized over the contract period using the straight-line method and charged to research and development expenses in the consolidated statements of operations. 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 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, expected volatility and fair value of underlying common share. 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. The expected volatility was estimated using historical volatility of share prices of similar public entities. No dividends were assumed for this calculation of option value. |
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. In determining the hypothetical shares repurchased, the Company uses the average share price for the period. In the case that earnings are negative, any potential common stock equivalents would have the effect of being anti-dilutive in the computation of net loss per share. |
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 bases of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are established when it is necessary to reduce deferred tax assets to the amount expected to be realized. Income tax expense is the tax payable for the period and the change during the period in deferred tax assets and liabilities. The Company recognizes and measures uncertain tax positions taken or expected to be taken in a tax return utilizing a two-step process. In the first step, recognition, the Company determines whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The second step addresses measurement of a tax position that meets the more-likely-than-not criteria. The tax position is measured at the largest amount of benefit that has a likelihood of greater than 50 percent of being realized upon ultimate settlement. |
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. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements In August 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 reduces the existing diversity in practice in financial reporting across all industries by clarifying certain existing principles in ASC 230, Statement of Cash Flows, (“ASC 230”) including providing additional guidance on how and what an entity should consider in determining the classification of certain cash flows. In addition, in November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230), Restricted Cash (“ASU 2016-18”). ASU 2016-18 clarifies certain existing principles in ASC 230, including providing additional guidance related to transfers between cash and restricted cash and how entities present, in their statement of cash flows, the cash receipts and cash payments that directly affect the restricted cash accounts. These ASUs are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the adoption of ASU 2016-15 to have a material effect on the Company’s consolidated financial statements. The adoption of ASU 2016-18 will modify the Company’s current disclosures by reclassifying certain balances within the consolidated statement of cash flows, but this is not expected to have a material effect on the Company’s consolidated financial statements. In March 2016, the FASB issued Accounting Standards Update No. 2016-09, “Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 can be applied either on a retrospective or prospective basis and is effective for fiscal years beginning after December 15, 2016 and interim periods within those years. The Company will adopt ASU 2016-09 in the first quarter of 2017. The primary impact of adoption will be the recognition of excess tax benefits within income tax provision rather than within shareholders’ equity, which the Company will adopt on a prospective basis. As the Company does not have a significant amount of excess tax benefits from share-based payment transactions, it does not expect the adoption of ASU 2016-09 to have a material effect on its consolidated financial statements. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”) in order to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under US GAAP. ASU 2016-02 requires that a lessee should recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term on the balance sheet. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those reporting periods using a modified retrospective approach and early adoption is permitted. The Company is performing a preliminary review of its contracts that are expected to be applied under the new guidance. In November 2015, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update No. 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes” (“ASU 2015-17”). The amendments in ASU 2015-17 require an entity to classify all deferred tax assets and liabilities as noncurrent. ASU 2015-17 is effective for fiscal years beginning after December 15, 2016 and interim periods within those years. The Company will adopt ASU 2015-17 in the first quarter of 2017. As the Company does not have a significant balance of current deferred tax assets and liabilities, it believes that the implementation of this guidance will have no material impact on its consolidated financial statements. In July 2015, the FASB issued Accounting Standards Update No. 2015-11, “Simplifying the Measurement of Inventory” (“ASU 2015-11”). Under this ASU, inventory will be measured at the lower of cost and net realizable value, and options that currently exist for market value will be eliminated. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. No other changes were made to the current guidance on inventory measurement. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016 and interim periods within those years. The Company will adopt ASU 2015-11 in the first quarter of 2017 and believes that the implementation of this guidance will have no material impact on its consolidated financial statements. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”). ASU 2014-09 supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605)”, and requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016 (the “Original Effective Date”), including interim periods within that reporting period, and can be adopted either retrospectively to each prior period presented or as a cumulative-effect adjustment as of the date of adoption, with early application permitted as of the Original Effective Date. In August 2015, the FASB issued ASU 2015-14 “Deferral of the Effective Date,” which defers the required adoption date of ASU 2014-09 by one year. As a result of the deferred effective date, ASU 2014-09 will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. In March 2016, the FASB issued Accounting Standards Update No. 2016-08, “Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” (“ASU 2016-08”) clarifying the implementation guidance on principal versus agent considerations. Specifically, an entity is required to determine whether the nature of a promise is to provide the specified good or service itself (that is, the entity is a principal) or to arrange for the good or service to be provided to the customer by the other party (that is, the entity is an agent). The determination influences the timing and amount of revenue recognition. In May 2016, the FASB issued Accounting Standards Update No. 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients” (“ASU 2016-12”) clarifying how to assess collectibility, present sales tax, treat noncash consideration, and account for completed and modified contracts at the time of transition. In addition, ASU 2016-12 clarifies that an entity retrospectively applying the guidance in Topic 606 is not required to disclose the effect of the accounting change in the period of adoption. The effective date and transition requirements for ASU 2016-12, ASU 2016-08 and ASU 2014-09 are the same. Finally, ASU 2016-20 makes minor corrections or minor improvements to the Codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. The Company started analyzing the potential impact of applying the new guidance by reviewing its current accounting policies, customer arrangements and practices. The Company has not selected a transition method nor have we determined the effect of the standard to the Company’s consolidated financial statements. |
Recently Adopted Accounting Pronouncements - Interest-Imputation of Interest | Recently Adopted Accounting Pronouncements In April 2015, the FASB issued Accounting Standards Update No. 2015-03, “Interest—Imputation of Interest” (“ASU 2015-03”). ASU 2015-03 requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs would not be affected. Prior to the issuance of ASU 2015-03, debt issuance costs were required to be presented as an asset in the balance sheet. The Company adopted ASU 2015-03 in the first quarter of fiscal 2016 and recorded $3,203 thousand of debt issuance costs as a reduction of long-term borrowings as of December 31, 2016. Pursuant to ASU 2015-03, the Company reclassified all prior periods presented in its consolidated balance sheets to conform to the current period presentation, resulting in the reclassification of debt issuance costs of $3,781 thousand from other non-current assets to a reduction of long-term borrowings as of December 31, 2015. The adoption of ASU 2015-03 did not impact the Company’s consolidated statements of operations and cash flows. |
Recently Adopted Accounting Pronouncements - Presentation of Financial Statements - Going Concern | Recently Adopted Accounting Pronouncements In August 2014, the FASB issued Accounting Standards Update No. 2014-15, “Presentation of Financial Statements – Going Concern” (“ASU 2014-15”), which provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. ASU 2014-15 requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. An entity will be required to provide certain disclosures if conditions of events raise substantial doubt about the entity’s ability to continue as a going concern. ASU 2014-15 was effective for the Company in the fourth quarter of 2016. The adoption of ASU 2014-15 did not impact the Company’s consolidated financial statements. |
