Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, “Revenue from Contracts with Customers”, on revenue recognition. The new standard provides for a single five-step model to be applied to all revenue contracts with customers as well as requires additional financial statement disclosures that will enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows relating to customer contracts. Companies have an option to use either a retrospective approach or cumulative effect adjustment approach to implement the standard. As amended by ASU No. 2015-14 issued in August 2015, this ASU is effective for fiscal years and interim periods within those years beginning after December 15, 2017, with early adoption permitted. We do not intend to early adopt and are currently assessing the impact of this update, but preliminarily believe that its adoption will not have a material impact on our consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”. The amendments in this update state that in connection with preparing financial statements for each annual and interim reporting period, an entity’s management should evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued, when applicable). The amendments in this update are effective for the annual reporting period beginning after December 15, 2016 and for annual periods and interim periods thereafter. Early application is permitted. The adoption of this update did not have a material impact on our consolidated financial statements. In February 2016, the FASB ASU No. 2016-02, Leases. The new standard will require most leases to be recognized on the balance sheet which will increase reported assets and liabilities. Lessor accounting remains substantially similar to current guidance. The new standard is effective for annual and interim periods in fiscal years beginning after December 15, 2018, which for us is the first quarter of fiscal 2019 and mandates a modified retrospective transition method. We are currently assessing the impact of this update on our consolidated financial statements. In April 2016, the FASB issued ASU No. 2016-09, “Improvements to Employee Share-Based Payment Accounting”. The new standard simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. ASU No. 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted for financial statements that have not already been issued. The adoption of this update did not have a material impact on our consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments”. The new standard attempts to reduce diversity in practice in how cash receipts and cash payments are presented and classified in the statement of cash flows. ASU No. 2016-15 provides guidance on eight specific cash flow issues. The new guidance will be effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is permitted including adoption in an interim period. We do not intend to early adopt and we are currently assessing the impact of adoption of this update will have on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): “Simplifying the Test for Goodwill Impairment”. The update simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. It affects public entities that have goodwill reported in their financial statements and have not elected the private company alternative for the subsequent measurement of goodwill. A public entity that is a U.S. Securities and Exchange Commission ("SEC") filer should adopt the amendments in this update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. For the Company, the amendments are effective January 1, 2020. The Company is currently evaluating the impact of this ASU on its consolidated financial statements.
