Accounting Pronouncements	Accounting Pronouncement Recently Adopted In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718). The new guidance simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. In addition, the guidance provides an option to recognize forfeitures as they occur versus estimating them at the time of grant. The amendments in this standard are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company adopted ASU No. 2016-09 as required in the first quarter of fiscal year 2018 and has elected to continue the use of its forfeiture estimation method for share-based payment awards. The adoption of ASU 2016-09 did not have a material impact on the Company’s consolidated financial statements and related disclosures. In November 2016, the FASB issued ASU No. 2017‑18, Statement of Cash Flows (Topic 230): Restricted Cash, which provides amendments to current guidance to address the classification and presentation of changes in restricted cash in the statement of cash flows. The Company early adopted this ASU in the third quarter of fiscal year 2017 and retrospectively applied the change to the statement of cash flows for the fiscal years ended June 30, 2016. The Company disclosed its restricted cash on its consolidated balance sheets for the years presented. The adoption of this standard did not have a significant impact on the Company’s consolidated financial statements and related disclosures.
Accounting Pronouncements Not Yet Effective
Accounting Pronouncements	Accounting Pronouncements Not Yet Effective In June 2018, the FASB issued ASU No. 2018-7, Improvements to Nonemployee Share-Based Payment Accounting, The ASU supersedes ASC 505-50 and expands the scope of ASC 718 to include all share-based payment arrangements related to the acquisition of goods and services from both nonemployees and employees. The guidance will be effective for the Company in its first quarter of fiscal year 2020. The amendments should be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company has not yet determined whether it will elect early adoption, but it’s likely that the adoption of this standard will not have significant impact on its consolidated financial statements and related disclosures. In February 2018, the FASB issued ASU No. 2018-2, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, that allows companies to reclassify from Accumulated Other Comprehensive Income to Retained Earnings stranded tax effects resulting from the enactment of the Tax Cuts and Jobs Act (the "Tax Act"). The guidance will be effective for the Company in its first quarter of fiscal year 2020. Early adoption is permitted. The guidance should be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The Company has not yet selected a transition method, has not yet determined whether it will elect early adoption and is currently evaluating the impact of the adoption of this standard on its consolidated financial statements and related disclosures. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging. This guidance simplifies the application and administration of hedge accounting. The guidance amends the presentation and disclosure requirements and changes how companies assess effectiveness. The guidance is intended to more closely align hedge accounting with companies' risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. The guidance will be effective for the Company in its first quarter of fiscal year 2020. Early adoption is permitted. The guidance is required to be adopted on a prospective basis. The Company does not believe the adoption of this standard will have a material impact on its consolidated financial statements and related disclosures. In May 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2017‑09, Compensation—Stock Compensation (Topic 718)—Scope of Modification Accounting. This guidance redefines which changes to the terms and conditions of a share‑based payment award require an entity to apply modification accounting for a share‑based payment. This guidance will be effective for the Company in the first quarter of fiscal year 2019. The Company will adopt this guidance in the first quarter of fiscal year 2019 and has determined that the adoption of this standard will not have a significant impact on its consolidated financial statements. In March 2017, the FASB issued ASU No. 2017‑07, Compensation—Retirement Benefits (Topic 715)—Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This guidance revises the presentation of employer‑sponsored defined benefit pension and other postretirement plans for the net periodic benefit cost in the statement of operations and requires that the service cost component of net periodic benefit be presented in the same income statement line items as other employee compensation costs for services rendered during the period. The other components of the net benefit costs are required to be presented in the statement of operations separately from the service cost component and outside the subtotal of income from operations. This guidance allows only the service cost component of net periodic benefit costs to be eligible for capitalization. The guidance will be effective for the Company in the first quarter fiscal year 2019 and early adoption is permitted as of the beginning of an annual reporting period. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU No. 2017‑04, Intangibles—Goodwill and Other Topics (Topic 350)—Simplifying the Test for Goodwill Impairment. This guidance eliminates the requirement to calculate the implied fair value of goodwill of a reporting unit by determining the fair value of its assets and liabilities (including unrecognized assets and liabilities) to measure a goodwill impairment charge. Instead, an entity will record an impairment charge based on the excess of the reporting unit’s carrying amount over its fair value. The ASU will be effective for the Company in the first quarter of fiscal year 2021 on a prospective basis and earlier adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company will early adopt this guidance in the first quarter of fiscal year 2019 and has determined that the adoption of this standard will not have an impact on its consolidated financial statements and related disclosure. In August 2016, the FASB issued ASU No. 2016‑15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which clarifies the presentation and classification of certain cash receipts and cash payments in the statement of cash flows. This ASU will be effective for the Company in the first quarter of fiscal year 2019 and early adoption is permitted. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU No. 2016‑13 (ASU 2016‑13) Measurement of Credit Losses on Financial Instruments. ASU 2016‑13 requires measurement and recognition of expected credit losses for financial assets held. This guidance will become effective for the Company beginning in the third quarter of fiscal year 2020 and must be adopted using a modified retrospective approach, with certain exceptions. Early adoption is permitted beginning in the third quarter of fiscal year 2019. The Company has not yet determined whether it will elect early adoption and is evaluating the impact of the adoption of this standard on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016‑02, Leases (Topic 842) (ASU 2016‑02). Under the new guidance, a lessee will be required to recognize assets and liabilities for all leases with lease terms of more than 12 months. Consistent with current U.S. GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. ASU 2016‑02 requires additional disclosures. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. ASU 2016‑02 requires adoption based upon a modified retrospective transition approach. Early adoption is permitted. The Company is currently evaluating the impact of the pending adoption of ASU 2016‑02 on its consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09), to supersede nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. ASU 2014-09 is required to be adopted, using either of two methods: (i) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospective with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures. The guidance will be effective for the Company in the first quarter of fiscal year 2019. The Company adopted the new revenue standards as of July 1, 2018, using the modified retrospective transition method applied to those contracts which were not completed as of that date. The Company has substantially completed its assessment of the potential impact this guidance will have on its consolidated financial statements and related disclosures. Based on that assessment, the Company expects the most significant impact to be the capitalization and amortization of incremental costs of obtaining a contract, primarily related to certain bonuses and sales commissions. Under the new standards, the Company will capitalize incremental contract acquisition costs, such as certain bonuses and sales commissions, and amortize such costs over the period which the Company benefits, as estimated by management, which may extend beyond the initial contract term. The Company expects to amortize capitalized bonuses and sales commissions over a period of five years commencing upon the initial transfer of control of the system to the customer. The pattern of amortization will be commensurate with the pattern of transfer of control of the performance obligations to the customer. The Company will elect to use the practical expedient in ASC 340-40- 25-4 and expense commissions related to service renewals and upgrades with a renewal contract term of one year or less as incurred. For sales commissions that are capitalized, the Company expects to record an estimated net cumulative-effect adjustment to retained earnings of $1.9 million associated with open contracts as of July 1, 2018. The Company is currently evaluating the estimated impact for bonuses that are capitalized. The Company expects product revenue for direct sales to be accelerated to reflect transfer of control upon delivery while an element of installation will be deferred until performed. Prior to the adoption of ASC 606, the Company defers revenue until installation as occurred. The revenue recognition method for indirect sales and service revenues is expected to be unchanged under the new guidance. The Company will finalize its accounting assessment and quantitative impact of the adoption during the first quarter of fiscal year 2019.
