My Lords, I was saying that the Government have made an assessment of behavioural changes and they have produced figures which take those changes into account. Therefore, there has been a full assessment of the behavioural changes as best as can be done in advance of the change coming into effect. As I said, it is Treasury policy not to publish those assumptions but that work has been done. In terms of the cost to the Exchequer of this policy change, the figures were published at the time of the Budget and were subsequently revised, as I set out, at the time of the Autumn Statement.
