New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	(18) Recent Accounting Pronouncements In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting, which provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU 2017-09 is effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. The Company does not believe this new accounting standard update will have a material impact on its consolidated financial statements. In January 2017, the FASB issued 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 does not believe this new accounting pronouncement will have a material impact on its consolidated financial statements. 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 does not believe this new accounting pronouncement will have a material impact on its consolidated financial statements. 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. ASU 2019-09 requires that all tax benefits and deficiencies related to share-based payments be recognized and recorded through the statement of income for all awards settled or expiring after the adoption of ASU 2016-09. Under prior guidance, tax benefits in excess of compensation costs ("windfalls") were recorded in equity, and any tax deficiencies ("shortfalls") were recorded in equity to the extent of previous windfalls and then to the statement of income. ASU 2016-09 also requires, either prospectively or retrospectively, that all tax-related cash flows resulting from share-based payments be reported as operating activities on the statement of cash flows, a change from prior guidance that required windfall tax benefits to be presented as an inflow from financing activities and an outflow from operating activities on the statement of cash flows. Additionally, ASU 2016-09 allows entities to make an accounting policy election for the impact of most types of forfeitures on the recognition of expense for share-based payment awards by allowing the forfeitures to be either estimated, as was required under prior guidance, or recognized when they actually occur. Under ASU 2016-09, it is possible for equity awards to have a more dilutive effect on earnings per share (EPS). Under prior guidance, anticipated income tax windfalls and shortfalls were included in the calculation of assumed proceeds when applying the treasury stock method for computing the dilutive effect of share-based awards in the calculation of diluted EPS. Because there is no longer any excess tax benefits recognized in additional paid capital under ASU 2016-09, when applying the treasury stock method for computing diluted EPS, the assumed proceeds do not include any windfall tax benefits. As a result, fewer hypothetical shares can be repurchased under the treasury stock method, resulting in an assumption of more incremental shares being issued upon the exercise of shared-based awards. Therefore, equity awards have a more dilutive effect on EPS for any period where the average market price of an entity's underlying stock exceeds the average fair value of outstanding dilutive equity awards for the period. The provisions of ASU 2016-09 are effective for the Company at the beginning of fiscal 2018. The impact of ASU 2016-09 on the Company's income tax expense or benefit and related cash flows during and after the period of adoption are dependent in part upon future grants and vesting of stock-based compensation awards and other factors that are not fully controllable or predicable by the Company such as the future market price of the Company's common stock, the timing of employee exercises of vested stock options, and the future achievement of performance criteria that affect performance-based awards. Under ASU 2016-09, the Company will recognize forfeitures when they actually occur. 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. 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 adoption of this standard will not have any impact on the consolidated financial statements of the Company. 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 has made progress in its evaluation of the amended guidance, including identification of revenue streams. The Company recognizes revenue from product sales at the time of shipment and passage of title and risk of loss and control of the goods is transferred to the customer. The Company has no acceptance or other post-shipment obligations and does not offer product warranties or services to its customers. Although the Company is continuing to assess the impact of the amended guidance, Aceto generally anticipates that the timing of recognition of revenue will be substantially unchanged under the amended guidance. The Company is continuing to evaluate the impact on certain other transactions including third-party collaborations and other arrangements. The amended guidance will be effective for Aceto in the first quarter of fiscal 2019 and permits adoption under either the full retrospective approach (recognize effects of the amended guidance in each prior reporting period presented) or the modified retrospective approach (recognize the cumulative effect of adoption as an adjustment to retained earnings at the date of initial application). The Company anticipates adopting this amended standard on a modified retrospective basis.
