On 16 September 2015, the PRA published a letter sent to directors of insurers in relation to Solvency II implementation.  Amongst other matters, the PRA has confirmed (a) that its review of applications for Solvency II approvals is a priority and (b) its intention to shortly issue revised instructions on the need to split internal model outputs by line of business. An Annex to the letter contains guidance and PRA expectations regarding firms' use of the Transition Deduction to Technical Provisions.
