Aug. 31, 2017
Basis of Presentation	NOTE A – Basis of Presentation The consolidated financial statements include the accounts of Worthington Industries, Inc. and consolidated subsidiaries (collectively, “we,” “our,” “Worthington,” or the “Company”). Investments in unconsolidated affiliates are accounted for using the equity method. Significant intercompany accounts and transactions are eliminated. The Company owns controlling interests in the following five joint ventures: Spartan Steel Coating, LLC (“Spartan”) (52%), TWB Company, L.L.C. (“TWB”) (55%), Worthington Aritaş Basinçli Kaplar Sanayi (“Worthington Aritas”) (75%), Worthington Energy Innovations, LLC (“WEI”) (75%), and Worthington Specialty Processing (“WSP”) (51%). These joint ventures are consolidated with the equity owned by the other joint venture members shown as noncontrolling interests in our consolidated balance sheets, and their portions of net earnings and other comprehensive income (loss) (“OCI”) shown as net earnings or comprehensive income attributable to noncontrolling interests in our consolidated statements of earnings and consolidated statements of comprehensive income, respectively. These unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments, which are of a normal and recurring nature, except those which have been disclosed elsewhere in this Quarterly Report on Form 10-Q, necessary for a fair presentation of the consolidated financial statements for these interim periods, have been included. Operating results for the three months ended August 31, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending May 31, 2018 (“fiscal 2018”). For further information, refer to the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the fiscal year ended May 31, 2017 (“fiscal 2017”) of Worthington Industries, Inc. (the “2017 Form 10-K”). The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Recently Adopted Accounting Standards In July 2015, amended accounting guidance was issued regarding the measurement of inventory. The amended guidance requires that inventory accounted for under the first-in, first-out (FIFO) or average cost methods be measured at the lower of cost and net realizable value, where net realizable value represents the estimated selling price of inventory in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amended guidance has no impact on inventory accounted for under the last-in, first-out (LIFO) or retail inventory methods. The Company adopted this amended guidance on a prospective basis effective June 1, 2017. The adoption of this guidance did not impact our consolidated financial position or results of operations. Recently Issued Accounting Standards In May 2014, new accounting guidance was issued that replaces most existing revenue recognition guidance under U.S. GAAP. The new guidance requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Subsequently, additional guidance was issued on several areas including guidance intended to improve the operability and understandability of the implementation of principal versus agent considerations and clarifications on the identification of performance obligations and implementation of guidance related to licensing. The new guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The guidance permits the use of either the retrospective or cumulative effect transition method. We are in the process of evaluating the effect this guidance will have on the presentation of our consolidated financial statements and related disclosures. While we have not yet identified any material changes in the timing of revenue recognition, our evaluation is ongoing and not complete. We plan to adopt the new guidance in the first quarter of fiscal 2019. The Company will continue to monitor any modifications, clarifications, and interpretations by the FASB that may impact its conclusions. In February 2016, new accounting guidance was issued that replaces most existing lease accounting guidance under U.S. GAAP. Among other changes, the new guidance requires that lease assets and liabilities be recognized on the balance sheet by lessees for those leases classified as operating leases under previous guidance. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, and the change is to be applied using a modified retrospective approach as of the beginning of the earliest period presented. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and we have not determined the effect of the new guidance on our ongoing financial reporting. In June 2016, new accounting guidance was issued related to the measurement of credit losses on financial instruments. The new guidance changes the impairment model for most financial assets to require measurement and recognition of expected credit losses for financial assets held. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and we have not determined the effect of the new guidance on our ongoing financial reporting. In August 2016, amended accounting guidance was issued to clarify the proper cash flow presentation of certain specific types of cash payments and cash receipts. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and we have not determined the effect of the amended guidance on our ongoing financial reporting. In October 2016, amended accounting guidance was issued that requires the income tax consequences of an intra-entity transfer of an asset other than inventory to be recognized when the transfer occurs. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and have not determined the effect of the amended guidance on our ongoing financial reporting. In November 2016, amended accounting guidance was issued that requires amounts generally described as restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated cash flows. In January 2017, amended accounting guidance was issued to clarify the definition of a business to provide additional guidance to assist in evaluating whether transactions should be accounted for as an acquisition (or disposal) of either an asset or business. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated financial position or results of operations. In January 2017, amended accounting guidance was issued to simplify the goodwill impairment calculation, by removing Step 2 of the goodwill impairment test. Goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of the goodwill. The amended guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting. In March 2017, amended accounting guidance was issued that requires an employer to report the service cost component of pension and postretirement benefits in the same line as other current employee compensation costs. Additionally, other components of net benefit cost are to be presented in the income statement separately from the service cost component and outside of income from operations. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting. In May 2017, amended accounting guidance was issued to provide guidance about which changes to the terms or conditions of a share-based payment award require application of modification accounting. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated financial position or results of operations. In August 2017, amended accounting guidance was issued that modifies hedge accounting by making more hedge strategies eligible for hedge accounting, amending presentation and disclosure requirements, and changing how companies assess effectiveness. The intent is to simplify application of hedge accounting and increase transparency of information about an entity’s risk management activities. The amended guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting.
