(6)In accordance with the principle of proportionality, administrators of non-significant benchmarks and of regulated-data benchmarks should not be subject to an excessive administrative burden. It is therefore appropriate that such administrators should be able to opt out from certain quality requirements for those benchmarks. 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 certain requirements regarding the resilience of the methodology of the benchmark.
