1.  A supervised entity shall not add new references to a significant benchmark or a combination of such benchmarks in the Union where that benchmark or combination of benchmarks is the object of a public notice issued by a competent authority or ESMA in accordance with Article 24a(6). A supervised entity shall not add new references to a critical benchmark, a commodity benchmark subject to Annex II, an EU Climate Transition Benchmark, an EU Paris-aligned Benchmark or a combination that includes any such benchmarks in the Union where the administrator of those benchmarks is not included in the register referred to in Article 36.

Supervised entities shall regularly consult ESAP or the register referred to in Article 36 to verify the regulatory status of the administrators of critical benchmarks, significant benchmarks, commodity benchmarks subject to Annex II, EU Climate Transition Benchmarks or EU Paris-Aligned Benchmarks they intend to use.

By way of derogation from the first subparagraph, and where necessary to avoid serious market disruptions, ESMA or the competent authority, as applicable, may allow the use of a benchmark subject to a public notice issued in accordance with Article 24a(6) for a period of between 6 and 24 months following the publication of the public notice.

ESMA or the competent authority shall determine the duration of the period referred to in the third subparagraph taking into account:
(a) the total value of financial instruments or financial contracts within the Union for which the benchmark serves as a reference and of investment funds within the Union for which it is used to measure the performance;
(b) the availability of alternative benchmarks;
(c) the complexity of replacing the benchmark and the time needed to reduce, hedge or offset existing exposures.

1a.  A supervised entity may also use the replacement for a benchmark designated in accordance with Article 23b or Article 23c.

1b.  A supervised entity that uses a benchmark in existing financial contracts or financial instruments that is subject to a public notice under Article 24a(6) shall replace that benchmark with an appropriate alternative within 6 months of the publication of that notice, or issue and publish a statement on its website providing clients with a reasoned explanation for not being able to do so.

2.  Where the object of a prospectus to be published under Regulation (EU) 2017/1129 of the European Parliament and of the Council or Directive 2009/65/EC is transferable securities or other investment products that reference a critical benchmark, a significant benchmark, a commodity benchmark subject to Annex II of this Regulation, an EU Climate Transition Benchmark, or an EU Paris-aligned Benchmark, the issuer, offeror, or person asking for admission to trade on a regulated market shall ensure that the prospectus also includes clear and prominent information stating whether the benchmark is provided by an administrator included in the register referred to in Article 36 of this Regulation.

Where the object of a prospectus to be published under Regulation (EU) 2017/1129 or Directive 2009/65/EC is transferable securities or other investment products that reference a critical benchmark, a significant benchmark, a commodity benchmark subject to Annex II of this Regulation, an EU Climate Transition Benchmark, or an EU Paris-aligned Benchmark, the issuer, offeror, or person asking for admission to trade on a regulated market shall ensure that when a public notice pursuant to Article 24a(6) of this Regulation on the benchmark used is included in the register referred to in Article 36 of this Regulation the prospectus also includes, without undue delay following the publication of the public notice, that information in a clear and prominent manner.
