(5)The oversight function can include committees with specific, dedicated competencies, for different benchmarks or families of benchmarks or it can include multiple functions carrying out different tasks when persons with appropriate expertise cannot all sit on one committee, for example when they are based in different geographical regions. Those oversight functions need to have a single natural person or a committee in charge of the direction of the oversight function and responsible for interaction with the management body of the administrator and with the competent authority to facilitate the centralisation of oversight.
