(24)The segmentation of insurance and reinsurance obligations into lines of business and homogeneous risk groups should reflect the nature of the risks underlying the obligation. The nature of the underlying risks may justify segmentation which differs from the allocation of insurance activities to life insurance activities and non-life insurance activities, from the classes of non-life insurance set out in Annex I of Directive 2009/138/EC and from the classes of life insurance set out in Annex II of Directive 2009/138/EC.
