Based on Paragraph CA-4.8.13, when a diminishing Musharakah contract is related to a specific fixed asset/real estate leased to a customer under an Ijara contract, the Islamic bank licensee's credit exposure is similar to an exposure under a Musharakah with an Ijara sub-contract. In this case, the Musharakah investment is assigned a RW based on the credit standing of the counterparty/lessee, as rated by an ECAI that is approved by the CBB, and 100% RW on residual value of an asset. In case the counterparty is unrated, a RW of 100% applies.
