Basis of Accounting [Text Block] | 2. Basis of Presentation and Immaterial Correction of Comprehensive Loss The condensed consolidated balance sheet as of January 31, 2022, for the Company has been derived from audited consolidated financial statements. The unaudited interim condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2022 (“fiscal 2022”). In the opinion of the Company’s management, all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the financial position as of October 31, 2022, the results of operations for the three and nine months ended October 31, 2022 and 2021, the cash flows for the nine months ended October 31, 2022 and 2021, and the statement of stockholders’ equity for the three and nine months ended October 31, 2022 and 2021, have been included in these condensed consolidated financial statements. The foregoing interim results are not necessarily indicative of the results of operations to be expected for the full fiscal year ending January 31, 2023 (“fiscal 2023”). The Company has corrected an immaterial error in the statements of comprehensive loss for the three and nine months ended October 31, 2021, which as previously presented, incorrectly included $688,000 and $2.0 million of preferred dividends as a component of comprehensive loss, respectively. Additionally, during the years ended January 31, 2022 and 2021, comprehensive loss incorrectly included preferred dividends of $2.9 million and $2.3 million, respectively. Comprehensive loss will be corrected by revising the amounts included in previously-issued statements of comprehensive loss the next time they are required to be filed for comparative purposes.
