Underwritings of capital instruments issued by other banking, financial or insurance entities are covered in Subparagraph CA-2.4.16(c) and CA-2.4.20(c). The large exposures limits of Chapter CM-4 apply for underwritings. This means the 800% risk weights apply for underwritings in excess of the limits set in Chapter CM-4. The risk weights below apply for exposures within the limits of Chapter CM-4. Where an Islamic bank licensee has acquired assets on its balance sheet in the banking book which it is intending to place with third parties under a formal arrangement, the following risk weightings apply for no more than 90 days. Once the underwriting period has expired, the usual risk weights must apply.
