Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | GENERAL The unaudited interim consolidated financial statements included for A. Schulman, Inc. (the “Company”) reflect all adjustments, which are, in the opinion of management, necessary for a fair statement of the results of the interim periods presented. All such adjustments are of a normal recurring nature. The fiscal year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. The unaudited consolidated financial information should be read in conjunction with the consolidated financial statements and notes thereto incorporated in the Company's Annual Report on Form 10-K for the fiscal year ended August 31, 2016 . The results of operations for the three months ended November 30, 2016 are not necessarily indicative of the results expected for the fiscal year ending August 31, 2017 . The accounting policies for the periods presented are the same as described in Note 1 – Business and Summary of Significant Accounting Policies to the consolidated financial statements contained in the Company's Annual Report on Form 10-K for the fiscal year ended August 31, 2016 . Certain items previously reported in specific financial statement captions have been reclassified to conform to the fiscal 2017 presentation. CONSOLIDATING FINANCIAL INFORMATION Certain of our subsidiaries have guaranteed our obligations under the $375.0 million outstanding principal amount of 6.875% Senior Notes due June 2023 (the "Notes"). The following presents the condensed consolidating financial information separately for: (i) A. Schulman Inc. (“Parent”), the issuer of the guaranteed obligations; (ii) Guarantor subsidiaries (“Guarantors”), on a combined basis, as specified in the indentures related to the Company’s obligations under the Notes; (iii) Non-guarantor subsidiaries (“Non-Guarantors”), on a combined basis; (iv) Eliminations representing adjustments to (a) eliminate intercompany transactions between or among Parent, Guarantors and Non-Guarantors and (b) eliminate the investments in our subsidiaries; (v) A. Schulman, Inc. and Subsidiaries on a consolidated basis (“Consolidated”). Each Guarantor is 100% owned by Parent for each period presented. The Notes are fully and unconditionally guaranteed on a joint and several basis by each Guarantor. The guarantees of the Guarantors are subject to release in limited circumstances only upon the occurrence of certain customary conditions. Each entity in the consolidating financial information follows the same accounting policies as described in the notes to the consolidated financial statements, except for the use by Parent and Guarantors of the equity method of accounting to reflect ownership interests in subsidiaries which are eliminated upon consolidation. Changes in intercompany receivables and payables related to operations, such as intercompany sales or service charges, are included in cash flows from operating activities. Intercompany transactions reported as investing or financing activities include the sale of the capital stock of various subsidiaries, loans and other capital transactions between members of the consolidated group. Certain Non-Guarantors are limited in their ability to remit funds to it by means of dividends, advances or loans due to required foreign government and/or currency exchange board approvals or limitations in credit agreements or other debt instruments of those subsidiaries.
