My hon. Friend the Member for Amber Valley (Nigel Mills) has made absolutely the right point: as I said earlier, there are annual fees as well as incorporation fees, and we should look at both elements.
On the question of specifying a fee in the Bill, as the right hon. Member for Barking (Dame Margaret Hodge) says, we do not even know yet what duties will be required of the registrar, because the Bill has not yet passed through both Houses. The registrar may end up having more duties that will cost more to perform, so it is impossible to say right now what resources she will need. As the right hon. Lady says, we may discover further down the line that more will be required, so why would we set out the fee in the Bill rather than in regulations, where we can vary it more easily?
