Recital 6

(6)Benchmark administrators should monitor the use in the Union of the benchmarks they provide and notify the competent authority concerned or the European Supervisory Authority (European Securities and Markets Authority) (ESMA) established by Regulation (EU) No 1095/2010 of the European Parliament and of the Council ⁴ , depending on where that administrator is located, where the aggregate use of one of their benchmarks has reached the threshold of EUR 50 billion laid down in Article 24(1), point (a), of Regulation (EU) 2016/1011. Benchmark administrators frequently offer different variants of the benchmark to cater for the specific needs of benchmark users, including maturities or tenors, currencies and return calculation variants. Where such variants exist, their usage should be aggregated.
