We estimate losses on our net credit exposure to be between 0% - 5% for customers with high CQR, as these customers are investment grade or the equivalent of investment grade. We estimate losses on our net credit exposure to be between 2% - 15% for customers with average CQR, and between 15% - 100% for customers with low CQR, which includes customers in bankruptcy.
