Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended December 31, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2018. This report should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the fiscal year ended March 31, 2017, which are included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on June 14, 2017, as amended by the Form 10-K/A filed with the SEC on July 31, 2017. The accompanying consolidated financial statements have been prepared on a consistent basis with, and there have been no material changes to, except as noted below, the accounting policies described in Note 2, Summary of Significant Accounting Policies, to the consolidated financial statements that are presented in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2017. The Company has made certain reclassifications to its prior period consolidated statements of cash flows to conform to the current period presentation. Such reclassifications did not have a material effect on the Company’s consolidated financial statements.

Company Background and Organization [Abstract]
Company Background and Organization	1. Company Background and Organization Motorcar Parts of America, Inc. and its subsidiaries (the “Company”, or “MPA”) is a leading manufacturer, remanufacturer, and distributor of aftermarket automotive parts. These replacement parts are sold for use on vehicles after initial vehicle purchase. These automotive parts are sold to automotive retail chain stores and warehouse distributors throughout North America and to major automobile manufacturers for both their aftermarket programs and warranty replacement programs (“OES”). The Company’s products include systems for alternators and starters, electric vehicle power-train and battery technology The Company obtains used automotive parts, commonly known as Used Cores, primarily from its customers under the Company’s core exchange program. It also purchases Used Cores from vendors (core brokers). The customers grant credit to the consumer when the used part is returned to them, and the Company in turn provides a credit to the customers upon return to the Company. These Used Cores are an essential material needed for the remanufacturing operations. The Company has remanufacturing, warehousing and shipping/receiving operations for automotive parts in North America and Asia. In addition, the Company utilizes various third party warehouse distribution centers in North America. Pursuant to the guidance provided under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), for segment reporting, the Company has identified its chief executive officer as its chief operating decision maker (“CODM”), has reviewed the documents used by the CODM, and understands how such documents are used by the CODM to make financial and operating decisions

New Accounting Pronouncements [Abstract]
New Accounting Pronouncements	2. New Accounting Pronouncements New Accounting Pronouncements Not Yet Adopted Revenue Recognition In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, codified in ASC 606, “Revenue Recognition - Revenue from Contracts with Customers” (“ASC 606”), which amends the guidance in the former ASC 605, “Revenue Recognition”. ASC 606 is effective for annual periods beginning after December 15, 2016, and interim periods within that reporting period for a public entity. The Company may elect either a full retrospective transition method, which requires the restatement of all periods presented, or a modified retrospective transition method, which requires a cumulative-effect recognized as of the date of initial adoption. In August 2015, the FASB delayed the effective date by one year to annual periods beginning after December 15, 2017, and interim periods within that reporting period for a public entity. Accordingly, the updated standard is effective for the Company as of April 1, 2018 and the Company does not plan to early adopt. The Company is currently in the process of determining whether it will utilize the full or modified retrospective method of adoption allowed by the new standard and the impact on its consolidated financial statements and footnote disclosures. While the Company anticipates selecting the full retrospective method, that final determination will be driven by the changes required by ASC 606 and the Company’s ability to recast past financial statements based upon those requirements. The Company anticipates completing its assessment of the adoption method by the end of its current fiscal year. ASC 606 establishes the requirements for recognizing revenue from contracts with customers. The standard requires entities to apportion consideration from contracts to performance obligations on a relative standalone selling price basis, based on a five-step model. Under the new standard, revenue is recognized when a customer obtains control of a promised good or service and is recognized in an amount that reflects the consideration which the entity expects to receive in exchange for the good or service. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Due to the impact the new standard may have on the Company’s business processes, systems, and controls, a project team has been formed to evaluate and guide the implementation process. The Company has performed a preliminary assessment, which has included the identification of the key contractual terms in its primary revenue stream and the comparison of historical accounting policies and practices to the requirements of the new standard by revenue stream. The assessment has resulted in the identification of potential accounting differences that may arise from the application of the new standard. The implementation team has also made substantial progress in the contract review phase of the project which includes identifying the population of contracts for a deeper analysis of the potential accounting impacts of the new standard on individual contracts. During the third quarter, the implementation team continued to identify changes to business processes, systems and controls to support recognition, presentation and disclosure under the new standard. The detailed implementation plan for the second half of fiscal 2018 continues to be executed including such tasks as data gathering, identification of the new journal entries, training, design of new processes and controls as well as testing of the controls. The Company’s primary revenue stream is derived from the sale of remanufactured products to its customers pursuant to long-term customer contracts. The Company will continue to recognize revenue at a point in time as it satisfies its performance obligation of transferring control of the product to the customer. The Company recognizes revenues net of anticipated returns, marketing allowances, volume discounts and other forms of variable consideration more fully described below. The Company also reviewed customer options to acquire additional goods or services and has preliminarily determined no material rights exist within its contracts. The Company does not currently anticipate that the adoption of ASU 2014-09 to have a material impact on previously reported revenue amounts. See discussion regarding nominally priced Remanufactured Cores below. The Company currently anticipates that the adoption of ASU 2014-09 will primarily impact reclassifications to certain balance sheet accounts to conform to the presentation and disclosure requirements of ASC 606. For example, the Company currently accounts for fully priced Remanufactured Cores anticipated to be returned as long-term core inventory and the refund liability as a contra-account receivable account as illustrated in Note 5 of the condensed notes to consolidated financial statements for the quarter ended December 31, 2017. Under ASC 606, the Company currently anticipates it will reclassify this asset to a contractual asset and recognize a contractual liability for amounts expected to be refunded to customers. The Company also analyzed specific contractual provisions related sales contracts which include nominally priced Remanufactured Cores. The Company recognizes revenue for sales of cores not expected to be replaced by a similar Used Core sent back under the core exchange program only upon meeting certain criteria as previously described in Note 2, Summary of Significant Accounting Policies, to the consolidated financial statements that are presented in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2017. The adoption of ASU 2014-09, may result in an acceleration of revenue recognition, as it requires the Company to estimate the amount of cores not expected to be returned upon the initial recognition of revenue for contracts which include nominally priced Remanufactured Cores. The Company currently does not expect that the change in the accounting policy for core exchange program to have a significant impact on the consolidated statements of operations. In order to properly determine the transaction price related to its sales contracts, the Company has also analyzed its various forms of consideration paid to its vendors including up-front payments for future contracts. Based on the analysis completed through the quarter ended December 31, 2017, the Company currently does not anticipate a change to its legacy accounting practices as a result of the adoption of ASU 2014-09 to account for up-front payments to its vendors. Under current accounting practices, if the Company expects to generate future revenues associated with an up-front payment, then an asset is recognized and amortized over the appropriate period of time as a reduction of revenue. If the Company does not expect to generate additional revenue then the up-front payment is recognized in the consolidated statements of operations when payment occurs as a reduction of revenue. The Company analyzes each up-front payment based on the substance and economics of the payment and therefore is not able to make an accounting policy election for such payments, consistent with views expressed by the FASB Transition Resource Group ("TRG") members in related discussions. ASU 2014-09 also codified the guidance on other assets and deferred costs relating to contracts with customers with the addition of ASC 340-40. This guidance relates to the accounting for costs of an entity to obtain and fulfill a contract to provide goods or services to the customer. Under the new guidance, an entity shall recognize as an asset the incremental costs of obtaining a contract with a customer if the entity expects to recover those costs. In the Company’s review of the various costs to obtain contracts with customers, it has preliminarily determined that currently no significant costs are incurred that meet the capitalization criteria. The Company’s primary cost to fulfill contracts relates to shipping and handling activities which continue to be expensed as incurred consistent with historical accounting practices. The new guidance provides several practical expedients, for which the Company anticipates adopting. The first of these practical expedients allows a company to expense incremental costs of obtaining a contract as incurred if the amortization period would have been one year or less. As noted above, the Company has preliminarily concluded that it does not have any such costs that qualify for capitalization but will apply the practical expedient such that costs incurred in prospective periods qualify. Similarly, the Company plans to adopt guidance which allows for the effects of a significant financing component to be ignored if a company expects that the period between the transfer of the goods and services to the customer and payment will be one year or less. Finally, the Company plans to adopt guidance which allows a company to account for shipping and handling activities that occur after control of the related good transfers as fulfillment activities instead of assessing such activities as performance obligations. The Company continues to evaluate the impact of ASU 2014-09, related amendments and interpretive guidance will have on its consolidated financial statements. While the Company has made substantial progress in identifying the likely impacts of the new standard, it has not yet determined a range of the potential quantitative impacts for the potential differences described above. In summary, the Company does not expect there to be a significant impact to the amount of revenue previously recorded but does anticipate a significant impact related to the classification of certain assets and liabilities for the reasons discussed in the preceding paragraphs. Financial Instruments In January 2016, the FASB issued guidance that addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. A reporting entity should apply the new guidance by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The Company is currently evaluating the impact of the provisions of this guidance to its consolidated financial statements. Leases In February 2016, the FASB issued new guidance that requires balance sheet recognition of a right-of-use asset and lease liability by lessees for operating leases. The new guidance also requires new disclosures providing additional qualitative and quantitative information about the amounts recorded in the financial statements. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The new guidance requires a modified retrospective approach with optional practical expedients. The Company will adopt this guidance in the first quarter of fiscal 2020. The Company is currently evaluating the impact the provisions of this guidance will have on its consolidated financial statements, but expects that it will result in a significant increase to its long-term assets and liabilities on the consolidated balance sheets. Business Combinations In January 2017, the FASB issued guidance which clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The new guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. . The adoption of this guidance is not expected to have any material impact on the Company’s consolidated financial statements. Goodwill Impairment In January 2017, the FASB issued guidance which simplifies the test for goodwill impairment. This standard eliminates Step 2 from the goodwill impairment test, instead requiring an entity to recognize a goodwill impairment charge for the amount by which the goodwill carrying amount exceeds the reporting unit’s fair value. This guidance is effective for interim and annual goodwill impairment tests in fiscal years beginning after December 15, 2019 with early adoption permitted. This guidance must be applied on a prospective basis. Modifications to Share-Based Payment Awards In May 2017, the FASB issued guidance to provide clarity and reduce (i) the diversity in practice and (ii) the cost and complexity when applying the accounting guidance for equity-based compensation to a change to the terms or conditions of a share-based payment award. This update provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. This guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017 with early adoption permitted. This guidance should be applied prospectively to an award modified on or after that adoption date. The adoption of this guidance is not expected to have any material impact on the Company’s consolidated financial statements. Derivatives and Hedging In August 2017, the FASB issued guidance to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. The amendments in this update also make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years; the guidance allows for early adoption in any interim period after issuance of the update. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements.

Accounts Receivable - Net	5. Accounts Receivable — Net Included in accounts receivable — net are significant offset accounts related to customer allowances earned, customer payment discrepancies, returned goods authorizations (“RGA”) issued for in-transit unit returns, estimated future credits to be provided for Used Cores returned by the customers and potential bad debts. Due to the forward looking nature and the different aging periods of certain estimated offset accounts, the offset accounts may not, at any point in time, directly relate to the balances in the accounts receivable-trade account. Accounts receivable — net is comprised of the following: December 31, 2017 March 31, 2017 Accounts receivable — trade $ 98,571,000 $ 76,902,000 Allowance for bad debts (4,160,000 ) (4,140,000 ) Customer allowances earned (13,579,000 ) (7,880,000 ) Customer payment discrepancies (1,513,000 ) (751,000 ) Customer returns RGA issued (28,917,000 ) (12,710,000 ) Customer core returns accruals (47,072,000 ) (25,404,000 ) Less: total accounts receivable offset accounts (95,241,000 ) (50,885,000 ) Total accounts receivable — net $ 3,330,000 $ 26,017,000 Warranty Returns The Company allows its customers to return goods that their customers have returned to them, whether or not the returned item is defective (“warranty returns”). The Company accrues an estimate of its exposure to warranty returns based on a historical analysis of the level of this type of return as a percentage of total unit sales. Amounts charged to expense for these warranty returns are considered in arriving at the Company’s net sales. At December 31, 2017 and March 31, 2017, the Company’s total warranty return accrual was $29,020,000 and $14,286,000, respectively, of which $21,410,000 and $5,303,000, respectively, was included in the customer returns RGA issued balance in the above table for expected credits to be issued against accounts receivable and $7,610,000 and $8,983,000, respectively, was included in the customer finished goods returns accrual in the consolidated balance sheets for estimated future warranty returns.

Debt [Abstract]
Debt	8. Debt The Company has the following credit agreements. Credit Facility The Company is party to a $145,000,000 senior secured financing, as amended, (the “Credit Facility”) with the lenders party thereto, and PNC Bank, National Association, as administrative agent, consisting of (i) a $120,000,000 revolving loan facility, subject to borrowing base restrictions and a $15,000,000 sublimit for letters of credit (the “Revolving Facility”) and (ii) a $25,000,000 term loan facility (the “Term Loans”). The loans under the Credit Facility mature on June 3, 2020. In connection with the Credit Facility, the lenders were granted a security interest in substantially all of the assets of the Company. The Credit Facility permits the payment of up to $10,000,000 of dividends per calendar year, subject to a minimum availability threshold and pro forma compliance with financial covenants. This amount was increased to $15,000,000 under the April 2017 amendment to the Credit Facility. In April 2017, the Company entered into a consent and fourth amendment to the Credit Facility (the “Fourth Amendment”) which, among other things, (i) increased the borrowing base limit with respect to inventory located in Mexico, (ii) amended the definition and calculation of consolidated EBITDA to raise the limitation on the add-back for non-capitalized transaction expenses related to the expansion of operations in Mexico, (iii) increased the annual limit on permitted stock repurchases and dividends, and (iv) modifies certain other categories (including increasing certain baskets for permitted acquisitions) and thresholds to, among other things, further accommodate the expansion of operations in Mexico. In July 2017, the Company entered into a fifth amendment to the Credit Facility (the “Fifth Amendment”) which, among other things, amended the definition of permitted acquisitions, permitted indebtedness, and pledge agreements. The Term Loans require quarterly principal payments of $781,250. The Credit Facility bears interest at rates equal to either LIBOR plus a margin of 2.50%, 2.75% or 3.00% or a reference rate plus a margin of 1.50%, 1.75% or 2.00%, in each case depending on the senior leverage ratio as of the applicable measurement date. There is also a facility fee of 0.25% to 0.375%, depending on the senior leverage ratio as of the applicable measurement date. The interest rate on the Company’s Term Loans and Revolving Facility was 4.12% and 4.33%, respectively, at December 31, 2017 and 3.29% and 3.55%, respectively, at March 31, 2017. The Credit Facility, among other things, requires the Company to maintain certain financial covenants including a maximum senior leverage ratio and a minimum fixed charge coverage ratio. The Company was in compliance with all financial covenants as of December 31, 2017. In addition to other covenants, the Credit Facility places limits on the Company’s ability to incur liens, incur additional indebtedness, make loans and investments, engage in mergers and acquisitions, engage in asset sales, redeem or repurchase capital stock, alter the business conducted by the Company and its subsidiaries, transact with affiliates, prepay, redeem or purchase subordinated debt, and amend or otherwise alter debt agreements. The following summarizes information about the Company’s Term Loans at: December 31, 2017 March 31, 2017 Principal amount of term loan $ 17,969,000 $ 20,312,000 Unamortized financing fees (231,000 ) (313,000 ) Net carrying amount of term loan 17,738,000 19,999,000 Less current portion of term loan (3,068,000 ) (3,064,000 ) Long-term portion of term loan $ 14,670,000 $ 16,935,000 Future repayments of the Company’s Term Loans are as follows: Year Ending March 31, 2018 - remaining three months 781,000 2019 3,125,000 2020 3,125,000 2021 10,938,000 Total payments $ 17,969,000 The Company had $36,000,000 and $11,000,000 outstanding under the Revolving Facility at December 31, 2017 and March 31, 2017, respectively. In addition, $260,000 was reserved for standby letters of credit for workers’ compensation insurance and $600,000 for commercial letters of credit at December 31, 2017. At December 31, 2017, $83,140,000, subject to certain adjustments, was available under the Revolving Facility. WX Agreement In August 2012, the Company entered into a Revolving Credit/Strategic Cooperation Agreement (the “WX Agreement”) with Wanxiang America Corporation (the “Supplier”) and the discontinued subsidiaries. In connection with the WX Agreement, the Company issued a warrant (the “Supplier Warrant”) to the Supplier to purchase up to 516,129 shares of the Company’s common stock for an exercise price of $7.75 per share exercisable at any time after August 22, 2014 and on or prior to September 30, 2017. On September 8, 2017, the Supplier exercised the Supplier Warrant in full and paid the Company $4,000,000. As a result of the exercise, the Supplier Warrant is no longer outstanding. The fair value of the Supplier Warrant on the exercise date was $9,566,000 using level 3 inputs and the Monte Carlo simulation model. The following assumptions were used to calculate the fair value of the Supplier Warrant: dividend yield of 0%, expected volatility of 26.4%, risk-free interest rate of 0.96%, subsequent financing probability of 0%, and an expected life of 0.06 years. The Company recorded a non-cash reclassification of the Supplier Warrant’s fair value to shareholders’ equity on the exercise date, with no further adjustments to the fair value of the Supplier Warrant being required. The fair value of the Supplier Warrant was $11,879,000 at March 31, 2017 and was included in other liabilities in the consolidated balance sheet. During the nine months ended December 31, 2017 and 2016, a gain of $2,313,000 and $5,727,000, respectively, was recorded in general and administrative expenses due to the change in the fair value of this warrant liability. A gain of $962,000 was recorded in general and administrative expenses during the three months ended December 31, 2016 due to the change in the fair value of this warrant liability.

Net (Loss) Income Per Share	10. Net (Loss) Income Per Share Basic net (loss) income per share is computed by dividing net (loss) income by the weighted average number of shares of common stock outstanding during the period. Diluted net (loss) income per share includes the effect, if any, from the potential exercise or conversion of securities, such as stock options and warrants, which would result in the issuance of incremental shares of common stock. The following presents a reconciliation of basic and diluted net (loss) income per share: Three Months Ended December 31, Nine Months Ended December 31, 2017 2016 2017 2016 Net (loss) income $ (6,806,000 ) $ 11,110,000 $ 7,121,000 $ 27,761,000 Basic shares 19,069,152 18,675,125 18,814,967 18,587,946 Effect of potentially dilutive securities - 766,140 585,777 811,911 Diluted shares 19,069,152 19,441,265 19,400,744 19,399,857 Net (loss) income per share: Basic net (loss) income per share $ (0.36 ) $ 0.59 $ 0.38 $ 1.49 Diluted net (loss) income per share $ (0.36 ) $ 0.57 $ 0.37 $ 1.43 The effect of dilutive options excludes (i) 1,170,441 shares subject to options with exercise prices ranging from $4.17 to $34.17 per share for the three months ended December, 31, 2017, (ii) 292,415 shares subject to options with exercise prices ranging from $26.47 to $34.17 per share for the three months ended December, 31, 2016, (iii) 289,572 shares subject to options with exercise prices ranging from $28.68 to $34.17 per share for the nine months ended December 31, 2017, and (iv) 291,215 shares subject to options with exercise prices ranging from $28.68 to $34.17 per share for the nine months ended December 31, 2016, which were anti-dilutive.

Income Taxes The Company recorded income tax expense for the three months ended December 31, 2017 and 2016 of $7,756,000, or an effective tax rate of 816.4%, and $5,678,000, or an effective tax rate of 33.8%. The Company recorded income tax expenses for the nine months ended December 31, 2017 and 2016 of $16,099,000, or an effective tax rate of 69.3%, and $13,459,000, or an effective tax rate of 32.7%, respectively. Effective tax rates for the three and nine months ended December 31, 2017 are blended rates reflecting the estimated benefit of one quarter of Federal tax rate reductions for fiscal 2018. These benefits were partially offset by a net one-time $6,835,000 unfavorable impact related to the new tax legislation in the United States. On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Reform Act”) was enacted into law, which changes various corporate income tax provisions within the existing Internal Revenue Code The Company is not under examination in any jurisdiction and the years ended March 31, 2017, 2016, and 2015 remain subject to examination. The Company believes no significant changes in the unrecognized tax benefits will occur within the next 12 months.

Financial Risk Management and Derivatives [Abstract]
Financial Risk Management and Derivatives	12. Financial Risk Management and Derivatives Purchases and expenses denominated in currencies other than the U.S. dollar, which are primarily related to the Company’s facilities overseas, expose the Company to market risk from material movements in foreign exchange rates between the U.S. dollar and the foreign currencies. The Company’s primary risk exposure is from fluctuations in the value of the Mexican peso and to a lesser extent the Chinese yuan. To mitigate these risks, the Company enters into forward foreign currency exchange contracts to exchange U.S. dollars for these foreign currencies. The extent to which forward foreign currency exchange contracts are used is modified periodically in response to the Company’s estimate of market conditions and the terms and length of anticipated requirements. The Company enters into forward foreign currency exchange contracts in order to reduce the impact of foreign currency fluctuations and not to engage in currency speculation. The use of derivative financial instruments allows the Company to reduce its exposure to the risk that the eventual cash outflow resulting from funding the expenses of the foreign operations will be materially affected by changes in exchange rates between the U.S. dollar and the foreign currencies. The Company does not hold or issue financial instruments for trading purposes. The forward foreign currency exchange contracts are designated for forecasted expenditure requirements to fund foreign operations. The Company had forward foreign currency exchange contracts with a U.S. dollar equivalent notional value of $29,263,000 and $26,880,000 at December 31, 2017 and March 31, 2017, respectively. These contracts generally have a term of one year or less, at rates agreed at the inception of the contracts. The counterparty to this derivative transaction is a major financial institution with investment grade credit rating; however, the Company is exposed to credit risk with this institution. The credit risk is limited to the potential unrealized gains (which offset currency fluctuations adverse to the Company) in any such contract should this counterparty fail to perform as contracted. Any changes in the fair values of forward foreign currency exchange contracts are reflected in current period earnings and accounted for as an increase or offset to general and administrative expenses. The following shows the effect of the Company’s derivative instruments on its consolidated statements of operations: Gain (Loss) Recognized within General and Administrative Expenses Derivatives Not Designated as Three Months Ended December 31, Nine Months Ended December 31, Hedging Instruments 2017 2016 2017 2016 Forward foreign currency exchange contracts $ (1,784,000 ) $ (964,000 ) $ (1,062,000 ) $ (2,150,000 ) The fair value of the forward foreign currency exchange contracts of $635,000 is included in other current liabilities in the consolidated balance sheet at December 31, 2017. The fair value of the forward foreign currency exchange contracts of $427,000 is included in prepaid and other current assets in the consolidated balance sheet at March 31, 2017.

These investments are classified as Level 1 as the shares of these mutual funds trade with sufficient frequency and volume to enable the Company to obtain pricing information on an ongoing basis. Forward Foreign Currency Exchange Contracts The forward foreign currency exchange contracts are primarily measured based on the foreign currency spot and forward rates quoted by the banks or foreign currency dealers. During the three months ended December 31, 2017 and 2016, a loss of $1,784,000 and $964,000, respectively, was recorded in general and administrative expenses due to the change in the value of the forward foreign currency exchange contracts. During the nine months ended December 31, 2017 and 2016, a loss of $1,062,000 and $2,150,000, respectively, was recorded in general and administrative expenses due to the change in the value of the forward foreign currency exchange contracts.

During the three and nine months ended December 31, 2017, the Company had no significant measurements of assets or liabilities at fair value on a nonrecurring basis subsequent to their initial recognition. The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to the short-term nature of these instruments. The carrying amounts of the revolving loan, term loan and other long-term liabilities approximate their fair value based on the variable nature of interest rates and current rates for instruments with similar characteristics.

Share-based Payments	14. Share-based Payments Stock Options The Company granted options to purchase 169,000 and 184,000 shares of common stock during the nine months ended December 31, 2017 and 2016, respectively. The cost associated with stock options is estimated using the Black-Scholes option-pricing model. This model requires the input of subjective assumptions including the expected volatility of the underlying stock and the expected holding period of the option. These subjective assumptions are based on both historical and other information. Changes in the values assumed and used in the model can materially affect the estimate of fair value. The following assumptions were used to derive the weighted average fair value of the stock options granted: Nine Months Ended December 31, 2017 2016 Weighted average risk free interest rate 1.91 % 1.38 % Weighted average expected holding period (years) 5.82 5.84 Weighted average expected volatility 47.31 % 47.42 % Weighted average expected dividend yield - - Weighted average fair value of options granted $ 12.66 $ 13.07 The following is a summary of stock option transactions: Number of Shares Weighted Average Exercise Price Outstanding at March 31, 2017 1,036,359 $ 14.92 Granted 169,000 $ 27.32 Exercised (28,951 ) $ 10.15 Forfeited (5,967 ) $ 28.55 Outstanding at December 31, 2017 1,170,441 $ 16.76 At December 31, 2017, options to purchase 324,959 shares of common stock were unvested at the weighted average exercise price of $28.26. At December 31, 2017, there was $3,361,000 of total unrecognized compensation expense related to unvested stock option awards.

Basis of Presentation [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended December 31, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2018. This report should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the fiscal year ended March 31, 2017, which are included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on June 14, 2017, as amended by the Form 10-K/A filed with the SEC on July 31, 2017. The accompanying consolidated financial statements have been prepared on a consistent basis with, and there have been no material changes to, except as noted below, the accounting policies described in Note 2, Summary of Significant Accounting Policies, to the consolidated financial statements that are presented in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2017. The Company has made certain reclassifications to its prior period consolidated statements of cash flows to conform to the current period presentation. Such reclassifications did not have a material effect on the Company’s consolidated financial statements.

New Accounting Pronouncements [Abstract]
New Accounting Pronouncements Not Yet Adopted	New Accounting Pronouncements Not Yet Adopted Revenue Recognition In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, codified in ASC 606, “Revenue Recognition - Revenue from Contracts with Customers” (“ASC 606”), which amends the guidance in the former ASC 605, “Revenue Recognition”. ASC 606 is effective for annual periods beginning after December 15, 2016, and interim periods within that reporting period for a public entity. The Company may elect either a full retrospective transition method, which requires the restatement of all periods presented, or a modified retrospective transition method, which requires a cumulative-effect recognized as of the date of initial adoption. In August 2015, the FASB delayed the effective date by one year to annual periods beginning after December 15, 2017, and interim periods within that reporting period for a public entity. Accordingly, the updated standard is effective for the Company as of April 1, 2018 and the Company does not plan to early adopt. The Company is currently in the process of determining whether it will utilize the full or modified retrospective method of adoption allowed by the new standard and the impact on its consolidated financial statements and footnote disclosures. While the Company anticipates selecting the full retrospective method, that final determination will be driven by the changes required by ASC 606 and the Company’s ability to recast past financial statements based upon those requirements. The Company anticipates completing its assessment of the adoption method by the end of its current fiscal year. ASC 606 establishes the requirements for recognizing revenue from contracts with customers. The standard requires entities to apportion consideration from contracts to performance obligations on a relative standalone selling price basis, based on a five-step model. Under the new standard, revenue is recognized when a customer obtains control of a promised good or service and is recognized in an amount that reflects the consideration which the entity expects to receive in exchange for the good or service. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Due to the impact the new standard may have on the Company’s business processes, systems, and controls, a project team has been formed to evaluate and guide the implementation process. The Company has performed a preliminary assessment, which has included the identification of the key contractual terms in its primary revenue stream and the comparison of historical accounting policies and practices to the requirements of the new standard by revenue stream. The assessment has resulted in the identification of potential accounting differences that may arise from the application of the new standard. The implementation team has also made substantial progress in the contract review phase of the project which includes identifying the population of contracts for a deeper analysis of the potential accounting impacts of the new standard on individual contracts. During the third quarter, the implementation team continued to identify changes to business processes, systems and controls to support recognition, presentation and disclosure under the new standard. The detailed implementation plan for the second half of fiscal 2018 continues to be executed including such tasks as data gathering, identification of the new journal entries, training, design of new processes and controls as well as testing of the controls. The Company’s primary revenue stream is derived from the sale of remanufactured products to its customers pursuant to long-term customer contracts. The Company will continue to recognize revenue at a point in time as it satisfies its performance obligation of transferring control of the product to the customer. The Company recognizes revenues net of anticipated returns, marketing allowances, volume discounts and other forms of variable consideration more fully described below. The Company also reviewed customer options to acquire additional goods or services and has preliminarily determined no material rights exist within its contracts. The Company does not currently anticipate that the adoption of ASU 2014-09 to have a material impact on previously reported revenue amounts. See discussion regarding nominally priced Remanufactured Cores below. The Company currently anticipates that the adoption of ASU 2014-09 will primarily impact reclassifications to certain balance sheet accounts to conform to the presentation and disclosure requirements of ASC 606. For example, the Company currently accounts for fully priced Remanufactured Cores anticipated to be returned as long-term core inventory and the refund liability as a contra-account receivable account as illustrated in Note 5 of the condensed notes to consolidated financial statements for the quarter ended December 31, 2017. Under ASC 606, the Company currently anticipates it will reclassify this asset to a contractual asset and recognize a contractual liability for amounts expected to be refunded to customers. The Company also analyzed specific contractual provisions related sales contracts which include nominally priced Remanufactured Cores. The Company recognizes revenue for sales of cores not expected to be replaced by a similar Used Core sent back under the core exchange program only upon meeting certain criteria as previously described in Note 2, Summary of Significant Accounting Policies, to the consolidated financial statements that are presented in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2017. The adoption of ASU 2014-09, may result in an acceleration of revenue recognition, as it requires the Company to estimate the amount of cores not expected to be returned upon the initial recognition of revenue for contracts which include nominally priced Remanufactured Cores. The Company currently does not expect that the change in the accounting policy for core exchange program to have a significant impact on the consolidated statements of operations. In order to properly determine the transaction price related to its sales contracts, the Company has also analyzed its various forms of consideration paid to its vendors including up-front payments for future contracts. Based on the analysis completed through the quarter ended December 31, 2017, the Company currently does not anticipate a change to its legacy accounting practices as a result of the adoption of ASU 2014-09 to account for up-front payments to its vendors. Under current accounting practices, if the Company expects to generate future revenues associated with an up-front payment, then an asset is recognized and amortized over the appropriate period of time as a reduction of revenue. If the Company does not expect to generate additional revenue then the up-front payment is recognized in the consolidated statements of operations when payment occurs as a reduction of revenue. The Company analyzes each up-front payment based on the substance and economics of the payment and therefore is not able to make an accounting policy election for such payments, consistent with views expressed by the FASB Transition Resource Group ("TRG") members in related discussions. ASU 2014-09 also codified the guidance on other assets and deferred costs relating to contracts with customers with the addition of ASC 340-40. This guidance relates to the accounting for costs of an entity to obtain and fulfill a contract to provide goods or services to the customer. Under the new guidance, an entity shall recognize as an asset the incremental costs of obtaining a contract with a customer if the entity expects to recover those costs. In the Company’s review of the various costs to obtain contracts with customers, it has preliminarily determined that currently no significant costs are incurred that meet the capitalization criteria. The Company’s primary cost to fulfill contracts relates to shipping and handling activities which continue to be expensed as incurred consistent with historical accounting practices. The new guidance provides several practical expedients, for which the Company anticipates adopting. The first of these practical expedients allows a company to expense incremental costs of obtaining a contract as incurred if the amortization period would have been one year or less. As noted above, the Company has preliminarily concluded that it does not have any such costs that qualify for capitalization but will apply the practical expedient such that costs incurred in prospective periods qualify. Similarly, the Company plans to adopt guidance which allows for the effects of a significant financing component to be ignored if a company expects that the period between the transfer of the goods and services to the customer and payment will be one year or less. Finally, the Company plans to adopt guidance which allows a company to account for shipping and handling activities that occur after control of the related good transfers as fulfillment activities instead of assessing such activities as performance obligations. The Company continues to evaluate the impact of ASU 2014-09, related amendments and interpretive guidance will have on its consolidated financial statements. While the Company has made substantial progress in identifying the likely impacts of the new standard, it has not yet determined a range of the potential quantitative impacts for the potential differences described above. In summary, the Company does not expect there to be a significant impact to the amount of revenue previously recorded but does anticipate a significant impact related to the classification of certain assets and liabilities for the reasons discussed in the preceding paragraphs. Financial Instruments In January 2016, the FASB issued guidance that addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. A reporting entity should apply the new guidance by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The Company is currently evaluating the impact of the provisions of this guidance to its consolidated financial statements. Leases In February 2016, the FASB issued new guidance that requires balance sheet recognition of a right-of-use asset and lease liability by lessees for operating leases. The new guidance also requires new disclosures providing additional qualitative and quantitative information about the amounts recorded in the financial statements. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The new guidance requires a modified retrospective approach with optional practical expedients. The Company will adopt this guidance in the first quarter of fiscal 2020. The Company is currently evaluating the impact the provisions of this guidance will have on its consolidated financial statements, but expects that it will result in a significant increase to its long-term assets and liabilities on the consolidated balance sheets. Business Combinations In January 2017, the FASB issued guidance which clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The new guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. . The adoption of this guidance is not expected to have any material impact on the Company’s consolidated financial statements. Goodwill Impairment In January 2017, the FASB issued guidance which simplifies the test for goodwill impairment. This standard eliminates Step 2 from the goodwill impairment test, instead requiring an entity to recognize a goodwill impairment charge for the amount by which the goodwill carrying amount exceeds the reporting unit’s fair value. This guidance is effective for interim and annual goodwill impairment tests in fiscal years beginning after December 15, 2019 with early adoption permitted. This guidance must be applied on a prospective basis. Modifications to Share-Based Payment Awards In May 2017, the FASB issued guidance to provide clarity and reduce (i) the diversity in practice and (ii) the cost and complexity when applying the accounting guidance for equity-based compensation to a change to the terms or conditions of a share-based payment award. This update provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. This guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017 with early adoption permitted. This guidance should be applied prospectively to an award modified on or after that adoption date. The adoption of this guidance is not expected to have any material impact on the Company’s consolidated financial statements. Derivatives and Hedging In August 2017, the FASB issued guidance to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. The amendments in this update also make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years; the guidance allows for early adoption in any interim period after issuance of the update. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements.
