The equity exposure in a Diminishing Musharakah contract, where the bank intends to transfer its full ownership in movable assets and working capital to the other partner over the life of the contract, is calculated based on the remaining balance of the amount invested (measured at historical cost including any share of undistributed profits) less any specific provision for impairment. The exposure shall be risk weighted according to the nature of the underlying assets as set out in paragraph CA-3.6.11 to CA-3.6.14 above. If a third party guarantee exists, to make good impairment losses, the RW of the guarantor shall be substituted for that of the assets (if lower) for the amount of any such guarantee.
