On 27 August 2010, CEIOPS updated its questions and answers document (Q&A) regarding QIS5. The latest version of the Q&A contains 24 answers on issues including solvency capital requirements and technical provisions. CEIPOS hosted a joint workshop with the Groupe Consultatif Actuariel European (GCAE) on 25 & 26 August 2010, after which the CGAE published notes, which are intended to act as an informal aid to practitioners.

On 30 August 2010, CEIPOS published a manual (which was again updated on 6 September) to assist firms with the internal model spreadsheets that form part of the Solvency II QIS5 exercise. The manual is based on the spreadsheet as of 23 August 2010 and covers the structure of the spreadsheets as well as their completion and submission.
