[1] Consolidated net revenues comprise interest and similar income, interest expenses and total noninterest income (including net commission and fee income); revenues are
attributed to countries based on the location in which the Group’s booking office is located; the location of a transaction on the Group’s books is sometimes different
from the location of the headquarters or other offices of a customer and different from the location of the Group’s personnel who entered into or facilitated the
transaction; where the Group records a transaction involving its staff and customers and other third parties in different locations frequently depends on other
considerations, such as the nature of the transaction, regulatory considerations and transaction processing considerations
