(51)For own fund items issued by a related undertaking to qualify as group own funds, they are to satisfy the requirements set out in Articles 71, 73, and 77 of Delegated Regulation (EU) 2015/35, with the reference to the ‘Solvency Capital Requirement’ in those Articles interpreted as applying to both the Solvency Capital Requirement of the issuing related undertaking and the group Solvency Capital Requirement. In the context of mergers and acquisitions, that requirement may prevent recognition of own fund instruments issued by an undertaking before it became part of the acquiring group, even where those instruments continue to meet all relevant prudential standards at the level of the undertaking itself. Such a limitation can create disproportionate capital costs associated with external growth, ultimately impairing the international competitiveness of Union insurance and reinsurance groups. To address that issue, it should be allowed, on a transitional and time-limited basis, to recognise such own fund items as non-available group own funds following the acquisition of the issuing undertaking.
