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. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. 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. A reporting entity should apply the amendment prospectively. 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. The Company is currently evaluating the impact the provisions of this guidance will have on its consolidated financial statements. 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.
