Accounting Policies	Accounting Policies We adhere to the same accounting policies in the preparation of our condensed consolidated interim financial statements as we do in the preparation of our full year consolidated financial statements.

For interim financial reporting purposes, income taxes are recorded based upon our estimated annual effective income tax.
Use of Estimates	Use of Estimates In order to present our financial statements in conformity with GAAP, we are required to make certain estimates and assumptions that impact our interim financial statements and supplementary disclosures. These estimates may use forecasted financial information based on reasonable information available, however are subject to change in the future. Additionally, unknown future impacts of COVID-19 may impact those estimates and assumptions as well. Significant estimates and assumptions are part of our accounting for sales allowances, deferred revenue, valuation of inventory, amortization and depreciation, intangibles and goodwill, and other reserves. We believe these estimates and assumptions are reasonable; however, they are based on management’s current knowledge of events and actions, and changes in facts and circumstances may result in revised estimates and impact actual results.
Impact of COVID-19	Impact of COVID-19 Our operating results for the fiscal years 2022 and 2021 were adversely impacted by the COVID-19 pandemic and its effects on the global economy. Given the uncertainty around the continued effects of the COVID-19 pandemic and macro-environment, we cannot reasonably predict the effect they will have on future periods. If once again we become materially and adversely impacted, we may have to consider adjustments to our operations, inventory, liquidity, capital expenditures and accounting estimates and reserves.
