We have performed the following procedures in respect of the Issuer’s stress testing: The Issuer provided us with the results output from the RCBC ACM for each quarter over the last twelve months to [date]. For the avoidance of doubt we have not independently verified the accuracy of the RCBC ACM. We confirmed that in each instance the results of the 8 scenarios, for each quarter, were recorded as “PASS”, using the following assumptions as disclosed in the RCBC ACM.
