These estimates and assumptions have been applied using methodologies that are consistent throughout the periods presented with consideration given to the potential impacts of the COVID-19 pandemic. However, actual results could differ materially from these estimates and be significantly affected by the severity and duration of the pandemic, the extent of actions to contain or treat COVID-19, how quickly and to what extent normal economic and operating activity can resume, and the severity and duration of the global economic downturn that may result from the pandemic.</span></div>
