FSA has published information for firms in the sale and rent back sector that will help them prepare for regulation if Treasury decides their business should come within FSA's remit. The guidance gives an outline of the authorisation process. Given the Treasury originally proposed to introduce the regime from 1 July but has still not announced whether it will, FSA would need to introduce an interim regime that will allow applicants to continue business while FSA considers their application. Firms already authorised will need to apply for a variation to their permission.
