New Accounting Pronouncements, Policy [Policy Text Block]	*Recently Adopted Accounting Pronouncements* Debt—Debt with Conversion and Other Options In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815- 40) (“ASU 2020-06”). The ASU 2020-06 simplifies the accounting for convertible instruments and application of the equity classification guidance and made certain disclosure amendments. In addition, this ASU also amends certain aspects of the earnings per share (“EPS”) guidance. ASU 2020-06 is effective for financial reporting periods beginning after December 15, 2021, except smaller reporting companies for which this ASU is effective for financial reporting periods beginning after December 15, 2023. Early adoption is permitted, and an entity should adopt this ASU as of the beginning of its annual fiscal year. The Company elected to early adopt ASU 2020-06 as of the first day of the fiscal year ending September 30, 2023, using the modified retrospective approach which allows for a cumulative-effect adjustment to the opening balance of retained earnings or accumulated deficit in the period of adoption. The adoption of ASU 2020-06 did not have any impact on the accumulated deficit or any other components of the condensed consolidated balance sheet as of October 1, 2022 nor did it have a material impact on earnings per share for the three months ended December 31, 2022. *Accounting Pronouncements Pending Adoption* Financial Instruments – Credit Losses In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326), which requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost. ASU 2016-13 is effective for smaller reporting companies for annual reporting periods beginning after December 15, 2022, including interim periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact of the new standard on its consolidated financial statements and related disclosures. Business Combinations In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 606): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires that an entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606 as if it had originated the contracts. Generally, this should result in an acquirer recognizing and measuring the acquired contract assets and contract liabilities consistent with how they were recognized and measured in the acquiree’s financial statements, if the acquiree prepared financial statements in accordance with U.S. GAAP. The amendment in this update is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The guidance should be applied prospectively to business combinations occurring on or after the effective date of the amendment in this update. The Company is evaluating the potential impact of this adoption on its consolidated financial statements and related disclosures. All other Accounting Standards Updates issued but not yet effective are not expected to have a material effect on the Company’s future consolidated financial statements or related disclosures.
