2. Where a financial entity uses the same ICT intra-group service provider as financial entities established in other Member States, or belongs to a group and shares ICT systems with financial entities of the same group established in other Member States, the TLPT authority of the financial entity shall contact the TLPT authorities of the other financial entities using the same ICT intra-group service provider or sharing ICT systems as part of the group and assess with them the feasibility and suitability of conducting a joint TLPT in their respect. A joint TLPT shall be preferred to an individual TLPT where it may result in reduction of costs and resources for the financial entities and for the TLPT authorities, provided that the soundness and efficacy of the testing is not prejudiced.
