The Islamic bank licensee is exposed to the risk on the amounts paid to the Mudarib, and as these amounts are made on a profit-sharing and loss-bearing basis they are treated under credit risk as equity positions in the banking book. In principle, the Islamic bank licensee's credit exposure is to the Mudarib, not to the ultimate customer; however, as described below, a structure may involve the use of a "repayment account" to receive progress payments from the ultimate customer, which transfers much of the credit risk to the latter.
