(35)Payment initiation service providers and account information service providers, when exclusively providing those services, do not hold client funds. Accordingly, it would be disproportionate to impose own funds requirements on those new market players. Nevertheless, it is important that they be able to meet their liabilities in relation to their activities. They should therefore be required to hold either professional indemnity insurance or a comparable guarantee. EBA should develop guidelines in accordance with Article 16 of Regulation (EU) No 1093/2010 on the criteria to be used by Member States to establish the minimum monetary amount of professional indemnity insurance or comparable guarantee. EBA should not differentiate between professional indemnity insurance and a comparable guarantee, as they should be interchangeable.
