Goodwill must be deducted in the calculation of CET1, including any goodwill included in the valuation of significant investments in the capital of banking, financial and Takaful entities that are outside the scope of regulatory consolidation. The full amount is to be deducted net of any associated deferred tax liability which would be extinguished if the goodwill becomes impaired or derecognised under IFRS or AAOIFI. The amount to be deducted in respect of mortgage servicing rights is set out in Paragraph CA-2.4.23A. Intangible assets other than goodwill and mortgage service rights are subject to transitional arrangements and are phased out as regulatory adjustments as outlined in Subparagraph CA-B.2.1(d).
