(5)This Regulation establishes an allocation arrangement, taking into account quantitative and qualitative factors. It is necessary to avoid causing undue material disadvantage on those ECAIs which, due to their more recent entrance in the market, present limited quantitative information, with the view to balancing prudential with market concerns. Therefore, where there is limited quantitative information, the relevance of the quantitative factors for deriving the mapping should be relaxed. Updates to the mapping should be made whenever this becomes necessary to reflect quantitative information collected after the entry into force of the present Regulation.
