In a binding PL, when a bank is exposed to default on the lease orderer's obligation to execute the lease contract, 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 urbun received from the lease orderer. The applicable RW shall 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 (refer to chapter CA-4). The bank may or may not have the right to recoup from the customer any loss on leasing or disposing of the asset after taking account of the HJ.
