During the nine months ended September 30, 2021, this uncertainty continued to result in a higher level of judgment related to its estimates and assumptions.

These estimates may change, as new events occur and additional information is obtained, and are recognized in the consolidated financial statements as soon as they become known. Actual results could differ materially from these estimates.</span></div>
