I would just say I think it's important to differentiate between the evidence around the decisions we did make and the decisions we didn't make. The assumptions that support the decisions that we did make are assumptions largely based on the work of the Chief Actuary, and those actuarial assumptions are available in various reports. They are quite detailed, and I'm happy to talk about those in a briefing. What's being talked about in the section that you referred to are the decisions we decided not to proceed with.
In terms of understanding what we use as assumptions, including things such as the $7.7 billion that is set aside to deal with longevity issues that might change, those are all very public parts of our decision.
