First, I shall repeat what I believe I said earlier. This adjustment would go two ways. We have talked about so many things as being a form of one-way traffic this afternoon, but that is not the case. However, we want to make sure that the Scottish Government are accountable for what they are responsible for under the construct in this Bill, which is the effects of their powers to set a Scottish rate of income tax. They are not accountable either for a windfall gain or a windfall loss-if you can have a windfall loss-resulting from things that are done by the UK Government subsequent to the setting of the block grant adjustment. If we set out a worked example of how this will operate, I would like to think that it will be made clearer.
