Sequential implementation following significant acquisition

7.1

In the event that a firm with IRB permission acquires a significant new business, it should discuss with the PRA whether sequential roll-out of the firm’s IRB approach to these exposures would be appropriate. In addition, the PRA would expect to review any existing time period and conditions for sequential roll-out and determine whether these remain appropriate.
