On 23 June 2014, the PRA published three letters on its Solvency II webpage which were issued to life and general insurance firms earlier in the month. The first is from the PRA's Insurance Directors and, amongst other items, sets out the progress required in order for firms to be ready to apply for internal model approval in 2015. The second letter invites firms to take part in a trial submission to apply (by 27 June, with a view to making the submission by 19 July) for use of the matching adjustment and includes a Q&A to clarify the information sought as part of the trial.  The third letter provides clarification on asset eligibility criteria for the matching adjustment.
