Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities when these values are not readily apparent from other sources. Estimates are assessed each period and updated to reflect current information, such as the economic considerations related to the impact that COVID-19 outbreaks could have on the Company’s significant accounting estimates. Accounting estimates and judgements are inherently uncertain and the actual results could differ from these estimates.</p>
