Goodwill and all other intangibles 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. With the exception of mortgage servicing rights, the full amount is to be deducted net of any associated deferred tax liability which would be extinguished if the intangible assets become impaired or derecognised under IFRS or AAOIFI. The amount to be deducted in respect of mortgage servicing rights is set out in the threshold deductions section below.
