New Accounting Pronouncements and Changes in Accounting Principles [Text Block] | 3 . RECENT ACCOUNTING PRONOUNCEMENTS In June 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018 - 7, Compensation – Stock Compensation (Topic 718 ), Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018 - 7” ), which amends and expands Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The standard requires entities to measure nonemployee share-based payment transactions by estimating the fair value of the equity instrument it is obligated to issue, measure the equity-classified nonemployee share-based payment awards at the grant date, and consider the probability of satisfying performance conditions when accounting for nonemployee share based payment awards with such conditions. ASU 2018 - 7 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that fiscal year. Accordingly, this guidance will be effective for the Company in the fiscal year beginning October 1, 2019. The Company is currently evaluating the impact adoption of this guidance, if any, will have on its consolidated financial statements and related disclosures. In February 2018, the FASB issued ASU 2018 - 02, Income Statement—Reporting Comprehensive Income (Topic 220 ). The amendments in this ASU allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. Consequently, the amendments eliminate the stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The amendments in this update also require certain disclosures about stranded tax effects. The guidance is effective for fiscal years beginning after December 15, 2018 with early adoption permitted, including interim periods within those years. The Company expects that the adoption of this ASU will not have a material impact on its consolidated financial statements. In November 2016, the FASB issued ASU No. 2016 - 18, Statement of Cash Flows (Topic 230 ), Restricted Cash, which amends Topic 230 to add or clarify guidance on the classification and presentation of restricted cash in the statement of cash flows. The standard requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The provisions of this guidance are to be applied using a retrospective transition method to each period presented. ASU 2016 - 18 was effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years, with early adoption permitted. The Company adopted ASU 2016 - 18 effective January 1, 2018. For the year ended September 30, 2018, the increase in restricted cash resulted primarily from restricted cash balances associated with the security deposit for the Company’s new office lease, as described in Note13 and restricted cash included in the assets acquired in the acquisition of Genasys, as described in Note 4, Acquisition. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows, other than the impact discussed above. In March 2016, the FASB issued ASU No. 2016 - 09, Compensation – Stock Compensation (Topic 718 ): Improvements to Employee Share-Based Payment Accounting . This guidance changes how companies account for certain aspects of share-based payments to employees. Among other things, under the new guidance, companies will no longer record excess tax benefits and certain tax deficiencies in additional paid-in-capital (“APIC”), but will instead record such items as income tax expense or benefit in the income statement, and APIC pools will be eliminated. Companies will apply this guidance prospectively. Another component of the new guidance allows companies to make an accounting policy election for the impact of forfeitures on the recognition of expense for share-based payment awards, whereby forfeitures can be estimated, as required today, or recognized when they occur. If elected, the change to recognize forfeitures when they occur needs to be adopted using a modified retrospective approach. The guidance was effective for the Company in the first quarter of fiscal 2018. The adoption of this standard resulted in the recognition of $1.1 million of gross deferred tax assets related to the historical excess tax benefits from stock based compensation what was not previously included in deferred tax assets and a corresponding increase in the Company’s valuation allowance. In February 2016, the FASB issued ASU 2016 - 02, Leases (Topic 842 ) , which issued new guidance related to leases that outlines a comprehensive lease accounting model and supersedes the current lease guidance. The new guidance requires lessees to recognize lease liabilities and corresponding right-of-use assets for all leases with lease terms of greater than 12 months. It also changes the definition of a lease and expands the disclosure requirements of lease arrangements. The new guidance must be adopted using the modified retrospective approach and will be effective for the Company in the fiscal year beginning October 1, 2019. Early adoption is permitted. The Company is currently evaluating the impact adoption of this guidance, if any, will have on its consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU No. 2014 - 09, Revenue from Contracts with Customers (“ASU 2014 - 09” ), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014 - 09 will replace most existing revenue recognition guidance in U.S. generally accepted accounting principles when it becomes effective. In July 2015, the FASB deferred the effective date of the standard by an additional year; however, it provided companies the option to adopt one year earlier, commensurate with the original effective date. Accordingly, the standard will be effective for the Company in the fiscal year beginning October 1, 2018. Subsequently the FASB has issued additional guidance (ASUs 2015 - 14; 2016 - 08; 2016 - 10; 2016 - 12; 2016 - 13; 2016 - 20 ). The adoption of this guidance by the Company, effective October 1, 2018, did not have a material impact on the Company’s consolidated financial statements (see Note 2, Basis of Presentation and Significant Accounting Policies – Revenue Recognition, for further detail).
