On 4 February 2015, EIOPA published technical information on the symmetric adjustment of the equity capital charge for Solvency II to assist insurers in calculating their solvency positions as at 31 December 2014 and 31 January 2015.  As of March 2015, this information will be updated on a monthly basis. (Re)insurers using the standard formula are required to hold a certain amount of regulatory capital to compensate for losses in the value of equities in adverse scenarios. The calculation of the symmetric adjustment of the capital charge is based on the behaviour of an equity index built by EIOPA exclusively for that purpose.
