Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements of Aceto Corporation and subsidiaries (“Aceto” or the “Company”) included herein have been prepared by the Company and reflect all adjustments (consisting solely of normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for all periods presented. Interim results are not necessarily indicative of results which may be achieved for the full year. The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses reported in those financial statements and the disclosure of contingent assets and liabilities at the date of the financial statements. These judgments can be subjective and complex, and consequently actual results could differ from those estimates and assumptions. The Company’s most critical accounting policies relate to revenue recognition; allowance for doubtful accounts; inventory; goodwill and other indefinite-life intangible assets; long-lived assets; environmental matters and other contingencies; income taxes; and stock-based compensation. These condensed consolidated financial statements do not include all disclosures associated with consolidated financial statements prepared in accordance with GAAP. Accordingly, these statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto contained in the Company’s Form 10-K for the year ended June 30, 2016.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-04 Intangibles - Goodwill and Other (Topic 350) which would eliminate the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, the amount of an impairment charge would be recognized if the carrying amount of a reporting unit is greater than its fair value. ASU 2017-04 is effective for public companies for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact of the provisions of ASU 2017-04. In January 2017, the FASB issued ASU 2017-01 Business Combinations (Topic 805): Clarifying the Definition of a Business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 is effective for public companies for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company is currently evaluating the impact of the provisions of ASU 2017-01. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. ASU 2016-15 is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact of the provisions of ASU 2016-15. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which will change certain aspects of accounting for share-based payments to employees. ASU 2016-09 is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2016. The Company is currently evaluating the impact of the provisions of ASU 2016-09. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) that replaces existing lease guidance. The new standard is intended to provide enhanced transparency and comparability by requiring lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet. The new guidance will continue to classify leases as either finance or operating, with classification affecting the pattern of expense recognition in the statement of income. ASU 2016-02 is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2018. The Company is currently evaluating the impact of the provisions of ASU 2016-02. In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740) Balance Sheet Classification of Deferred Assets. This ASU is intended to simplify the presentation of deferred taxes on the balance sheet and will require an entity to present all deferred tax assets and deferred tax liabilities as non-current on the balance sheet. Under the current guidance, entities are required to separately present deferred taxes as current or non-current. Netting deferred tax assets and deferred tax liabilities by tax jurisdiction will still be required under the new guidance. This guidance will be effective for Aceto beginning in the first quarter of fiscal 2018, with early adoption permitted. The Company does not believe this new accounting standard update will have a material impact on its consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330) – Simplifying the Measurement of Inventory. This ASU requires that an entity measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This guidance is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company does not believe this new accounting standard update will have a material impact on its consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40). This ASU provides guidance to determine when and how to disclose going-concern uncertainties in the financial statements. The new standard requires management to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosure in certain circumstances. ASU 2014-15 will be effective for all entities in the first annual period ending after December 15, 2016. Earlier adoption is permitted. ASU 2014-15 will be effective for the Company beginning June 30, 2017. The Company does not believe that this pronouncement will have an impact on its consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which is the new comprehensive revenue recognition standard that will supersede all existing revenue recognition guidance under U.S. GAAP. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to a customer in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In August 2015, the FASB subsequently issued ASU 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date, which approved a one year deferral of ASU 2014-09 for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. In March 2016 and April 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers - Principal versus Agent Considerations (Reporting Revenue Gross versus Net), and ASU 2016-10, Revenue from Contracts with Customers - Identifying Performance Obligations and Licensing, respectively, which further clarify the guidance related to those specific topics within ASU 2014-09. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers - Narrow Scope Improvements and Practical Expedients, to reduce the risk of diversity in practice for certain aspects in ASU 2014-09, including collectibility, noncash consideration, presentation of sales tax and transition. Additionally, in December 2016, the FASB issued ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. ASU 2016-20 makes minor corrections or minor improvements to the standard that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. The Company is currently evaluating the impact of adoption on its consolidated financial statements.
