Where the parent undertaking referred to in Article 260 is itself a subsidiary of an insurance holding company or a mixed financial holding company which has its head office in a third country or of a third-country insurance or reinsurance undertaking, Member States shall apply the verification provided for in Article 260 only at the level of the ultimate parent undertaking which is a third-country insurance holding company, a third-country mixed financial holding company, a third-country insurance undertaking or a third-country reinsurance undertaking.

Supervisory authorities may, however, in the absence of equivalent supervision referred to in Article 260, carry out a new verification at a lower level where a parent undertaking of insurance or reinsurance undertakings exists, whether at the level of a third-country insurance holding company, a third country mixed financial holding company, a third-country insurance undertaking or a third-country reinsurance undertaking.
