(25)In the light of the similarities between life reassurance covering mortality risk and non-life reinsurance, in particular the cover of insurance risks and the duration of the life reassurance contracts, the required solvency margin for life reassurance should be determined in accordance with the provisions laid down in this Directive for the calculation of the required solvency margin for non-life reinsurance; the home Member State should however be allowed to apply the rules provided for in Directive 2002/83/EC for the establishment of the required solvency margin in respect of life reassurance activities which are linked to investment funds or participating contracts.
