In case (a) the bank has the right to recoup any loss (as indicated in the previous paragraph) from the orderer, that right constitutes a claim receivable which is exposed to credit risk, and the exposure shall be measured as the amount of the asset's total acquisition cost to the bank, (less the market value of the asset as collateral subject to any haircut, and less the amount of any HJ, provided that the collateral is an eligible collateral or has been agreed as acceptable to the CBB). The applicable RW must be based on the standing of the obligor as rated by an ECAI that is approved by the CBB, and in the case the obligor is unrated, a RW of 100% shall apply. (See Section CA-4.2).
