(6)In accordance with the principle of proportionality, administrators of non-significant benchmarks should not be subject to an excessive administrative burden. With respect to their non-significant benchmarks, those administrators should therefore be able to opt out from certain requirements regarding their organisational structure. In addition, where it is justified in view of the nature, scale and complexity of their activities, the likelihood of a conflict of interest arising between the provision of the benchmark and any other activities of the administrator, and the level of discretion involved in the process of provision of the benchmark, certain benchmark administrators should be able to opt out from the requirement of specifying in their governance arrangements the procedure for the appointment of the management body.
