A placement of funds made under a Mudarabah contract may be subject to a Shari'a-compliant guarantee from a third party. Such a guarantee relates only to the Mudarabah capital, not to the return. In such cases, the capital must be treated as subject to credit risk with a risk-weighting equal to that of the guarantor provided that the RW of that guarantor is lower than the RW of the Mudarib as a counterparty. Otherwise, the RW of the Mudarib must apply; that is, a RW for "equity exposure in banking book" applies, as per Paragraphs CA-4.8.16 to 4.8.18.
