“Although it is generally accepted that financial undertakings, i.e. financial institutions and insurance undertakings, should also be subject to limitations to the deductibility of interest, it is equally acknowledged that these two sectors present special features which call for a more customised approach. As the discussions in this field were not sufficiently conclusive in the international and the Union context, it is not possible to provide specific rules in the financial and insurance sectors and Member States should therefore be able to exclude them from the scope of interest limitation rules”.
