Member States shall provide that, where an insurance or reinsurance undertaking authorised in another Member State carries on business through a branch, the supervisory authorities of the home Member State may, after having informed the supervisory authorities of the host Member State concerned, carry out themselves, or through the intermediary of persons appointed for that purpose, on-site verifications of the information necessary to ensure the financial supervision of the undertaking.

The authorities of the host Member State concerned may participate in those verifications.

Where a supervisory authority has informed the supervisory authorities of a host Member State that it intends to carry out on-site verifications in accordance with the first paragraph and where that supervisory authority is prohibited from exercising its right to carry out those on-site verifications or where the supervisory authorities of the host Member State are unable in practice to exercise their right to participate in accordance with the second paragraph, the supervisory authorities may refer the matter to EIOPA and request its assistance in accordance with Article 19 of Regulation (EU) No 1094/2010. In that case, EIOPA may act in accordance with the powers conferred on it by that Article.
