OSFI has prescribed a minimum capital floor for institutions that use the advanced internal ratings-based approach for credit risk. The Basel II capital floor
add-on
is determined by comparing a capital requirement under the Basel II standardized approach for credit risk, in addition to OSFI prescribed requirements for market risk and credit valuation adjustment RWA. A shortfall in the Basel III capital requirement as compared with the Basel II capital floor is added to RWA. Under this Basel II regulatory capital floor requirement, the Bank does not have a capital floor
add-on
as at October 31, 2021 (October 31, 2020 – nil).
