Academies Bill [HL]

Perusing the model funding agreement, I have one question on the specific issue of the general academies grant. Clause 50 talks about the amount of grant that would be available in the first year of conversion, and that the money would be on the same basis as that used by the local authority for determining the budget share of the predecessor maintained school. In the case of an academy free school where there is no predecessor, how would the funding for the first year be calculated so that people who are interested in setting up these interesting new schools can have some certainty?
