FSA is consulting on a specialist sourcebook for building societies. The new BSOCS would help societies moving away from traditional business models to have appropriate risk management systems and skills. The new sourcebook builds on existing guidance and will require each society to review its selfclassification and the implications of the new rules for its liquidity and wholesale funding models. FSA gives guidance on five models to help societies understand how they might comply with SYSC requirements, and expands it to look specifically at liquidity, funding and financial risk management. It asks for comments by 5 September.
