(13)This Directive should not apply to the provision of reinsurance cover carried out or fully guaranteed by a Member State for reasons of substantial public interest, in the capacity of reinsurer of last resort, in particular where because of a specific situation in a market, it is not feasible to obtain adequate commercial cover; in this regard, a lack of ‘adequate commercial cover’ should mainly mean a market failure which is characterised by an evident lack of a sufficient range of insurance offers, although excessive premiums should not per se imply inadequacy of that commercial cover. Article 1(2)(d) of this Directive also applies to arrangements between insurance undertakings to which Directives 73/239/EEC or 2002/83/EC apply and which aim to pool financial claims ensuing from major risks such as terrorism.
