59 / Schnitzer Steel Industries, Inc. Form 10-K 2017 SCHNITZER STEEL INDUSTRIES, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS Note 1 – Nature of Operations Founded in 1906, Schnitzer Steel Industries, Inc. (the “Company”), an Oregon corporation, is one of North America’s largest recyclers of ferrous and nonferrous scrap metal, including end-of-life vehicles, and a manufacturer of finished steel products. Prior to the fourth quarter of fiscal 2017, the Company's internal organizational and reporting structure supported two operating and reportable segments: the Auto and Metals Recycling ("AMR") business and the Steel Manufacturing Business ("SMB"). In the fourth quarter of fiscal 2017, in accordance with its plan announced in June 2017, the Company modified its internal organizational and reporting structure to combine its steel manufacturing operations, which had been reported as the SMB segment, with its Oregon metals recycling operations, which had been reported within the AMR segment, forming a new division named Cascade Steel and Scrap ("CSS"). This resulted in a realignment of how the Chief Executive Officer, who is considered the Company's chief operating decision maker, reviews performance and makes decisions on resource allocation. The Company began reporting on this new segment structure in the fourth quarter of fiscal 2017 as reflected in this Annual Report on Form 10-K. The segment data for the comparable periods presented has been recast to conform to the current period presentation for all activities of the reorganized segments. Recasting this historical information did not have an impact on the Company's consolidated financial performance for any of the periods presented. AMR buys and processes ferrous and nonferrous scrapmetal for sale to foreign and domestic steel producers or their representatives and procures salvaged vehicles and sells serviceable used auto parts from these vehicles through a network of self-service auto parts stores. These auto parts stores also supply the Company's shredding facilities with autobodies that are processed into saleable recycled scrap metal. CSS operates a steel mini-mill that produces a range of finished steel long products using recycled scrap metal and other raw materials. CSS's steel mill obtains substantially all of its scrap metal raw material requirements from its integrated metals recycling and joint venture operations. As of August 31, 2017, all of the Company’s facilities were located in the United States ("U.S.") and its territories and Canada. Note 2 – Summary of Significant Accounting Policies Principles of Consolidation The Consolidated Financial Statements include the accounts of the Company and its majority-owned and wholly-owned subsidiaries. The equity method of accounting is used for investments in joint ventures over which the Company has significant influence but does not have effective control. The cost method of accounting is used for investments in entities over which the Company is not able to exercise significant influence. All significant intercompany account balances, transactions, profits and losses have been eliminated. All transactions and relationships with potential variable interest entities are evaluated to determine whether the Company is the primary beneficiary of the entities, therefore requiring consolidation. The Company does not have any variable interest entities requiring consolidation. Discontinued Operations The results of discontinued operations are presented separately, net of tax, from the results of ongoing operations for all periods presented. The expenses included in the results of discontinued operations are the direct operating expenses incurred by the disposed components that may be reasonably segregated from the costs of the ongoing operations of the Company. Asset impairments related to the disposed components are also included in the results of discontinued operations. See Note 8 - Discontinued Operations and the Asset Impairment Charges (Recoveries), net section of this Note for further detail. Cash and Cash Equivalents Cash and cash equivalents include short-term securities that are not restricted by third parties and have an original maturity date of 90 days or less.
