Yes. So the system itself accounted for about 1 per cent of our customer base. The platform was due to be decommissioned actually around the time of the activity coming to light. However, you could have -- with the changes I outlined on the main platform, you could still in theory have phoned through to a customer service agent, you still have to authenticate, but then you would be able to ask the customer service agent to reset the PIN on that specific service.
The action we did take at the time was that we took away the ability for the vast majority of our customer service agents to be able to reset the PIN and we limited that to a very small number of customer service managers that we had in our call centre environment to try and address that specific issue, but as you rightly said, it wasn't decommissioned fully until around about 2010, that's correct.
