The extent to which the COVID-19 pandemic may directly or indirectly impact our business, financial condition, and results of operations is highly uncertain and subject to change. We considered the potential impact of the COVID-19 pandemic on our estimates and assumptions and, other than the inventory write-offs and reserves recorded related to REGEN-COV (see Note 6), there was not a material impact to our consolidated financial statements as of and for the year ended December 31, 2021; however, actual results could differ from those estimates and there may be changes to our estimates in future periods.</span></div>
