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 guidance 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 company. 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 application to be used in transition. 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 company. 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. The determination of utilizing the full retrospective or modified retrospective method of adoption 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 will continue to provide enhanced disclosures as it continues its assessment. 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 revenue streams 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 due to the new standard for individual contracts. During the second quarter, the team continued to identify changes to business processes, systems and controls to support recognition, presentation and disclosure under the new standard. A detailed implementation plan for the second half of fiscal 2018 has been developed and includes tasks around data gathering, identification of the new journal entries, training, design of new processes and controls as well as testing of the controls. The Company anticipates that the adoption of ASU 2014-09 will primarily impact the timing of revenue recognition for nominally priced Remanufactured Cores not expected to be replaced by a similar Used Core sent back under the core exchange program and will result in an acceleration of revenue recognition in addition to some changes to revenue related disclosures and financial statement presentation. Conversely, the Company does not expect there to be a significant effect, other than classification, upon the balance sheet for anticipated returned cores. The Company currently accounts for fully priced Remanufactured Cores anticipated to be returned as long term core inventory. Under ASC 606, the Company will reclassify this asset to a contractual asset and recognize a contractual liability for amounts expected to be refunded to customers. For certain contracts, the Company offers customer incentives that may be considered a material right to the customer under ASC 606. These incentives may result in the Company having multiple performance obligations in an agreement and may delay the timing of revenues. In addition, certain payments made to customers in connection with future contracts may be deferred and amortized over future periods. 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 impact. ASC 606 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. 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 ASC 606, related amendments and interpretive guidance will have on its consolidated financial statements. 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 Company is currently evaluating the impact the provisions of this guidance will have on its 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 Company is currently evaluating the impact the provisions of this guidance will have on its 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.
