As part of the adoption we estimated the current expected credit losses for certain classes of relevant assets. The amounts realized from the affected assets will depend on, among other factors, general business conditions, including the impacts from COVID-19, and could differ in the near term from carrying amounts reflected in the consolidated financial statements.
