On 2 May 2014, the Prudential Regulation Authority in the UK (PRA) issued slides on technical issues for general insurers intending to use an internal model for the purpose of Solvency II. The PRA's aim is to assist such insurers in improving the quality of their internal model submissions. Topics addressed in the slides include (a) an overview of the models and validation framework, (b) expert judgements and dependencies in internal models and (c) the PRA’s assessment of insurance risk.
