Basis of Accounting [Text Block] | Note 2. Basis of Presentation The unaudited condensed consolidated financial statements of Avalon and related notes included herein have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted consistent with such rules and regulations. The accompanying unaudited condensed consolidated financial statements and related notes should be read in conjunction with the consolidated financial statements and related notes included in Avalon’s 2020 Annual Report to Shareholders. The unaudited condensed consolidated financial statements include the accounts of Avalon, its wholly owned subsidiaries and those companies in which Avalon has managerial control. All significant intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, these unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the financial position of Avalon as of September 30, 2021, and the results of its operations and cash flows for the interim periods presented. The operating results for the interim periods are not necessarily indicative of the results to be expected for the full year. The condensed consolidated financial statements presented herein reflect our current estimates and assumptions that affect the reported amounts of assets and liabilities and related disclosures as of the date of the financial statements and reported amounts of revenues and expenses during the reporting periods presented. The coronavirus/COVID-19 pandemic (collectively referred to herein as "COVID-19") adversely impacted our financial position, results of operations, and cash flows during the nine months ended September 30, 2020. As a result of the government mandates being subsequently lifted, the COVID-19 pandemic had a limited impact on our results of operations during the nine months ended September 30, 2021. Due to the ongoing uncertainty of COVID-19, we cannot predict the future impact that the pandemic may have on our financial condition, results of operations or cash flows.
