Ms Amy Ball:

The work that was done on the strategy was completed in spring 2016. That covered five different options in the controllership model. This was in liaison with another group of advisers. We concurred with its recommendation on the gap funding model. Since then, the other group of advisers took on the responsibility of final recommendation on the ownership model, which was included in the published report in 2018. On that basis, PwC is not in a position to comment.
