(4)The Commission should be empowered to adopt the measures necessary for the implementation of Directive 2005/68/EC in order to take account of technical developments in the insurance sector or financial markets and to ensure the uniform application of that Directive. More particularly, those measures are designed to extend the list of legal forms, clarify or adjust the items constituting the solvency margin, increase the premiums or claims amounts used for the calculation of the solvency margin for certain reinsurance activities or contract types, alter the minimum guarantee fund, and clarify definitions. Since those measures are of general scope and are designed to amend non-essential elements of Directive 2005/68/EC, inter alia , by supplementing it with new non-essential elements, they must be adopted in accordance with the regulatory procedure with scrutiny provided for in Article 5a of Decision 1999/468/EC.
