(11)To ensure that the new non-preferred senior class of debt instruments meets the eligibility criteria as described in the TLAC standard and as set out in Directive 2014/59/EU, thereby enhancing legal certainty, Member States should ensure that those debt instruments have an original contractual maturity of at least one year, do not contain embedded derivatives and are not derivatives themselves, and that the relevant contractual documentation related to their issuance and, where applicable, the prospectus explicitly refer to their lower ranking under normal insolvency proceedings. Debt instruments with variable interest derived from a broadly used reference rate, such as Euribor or Libor, and debt instruments not denominated in the domestic currency of the issuer, provided that principal, repayment and interest are denominated in the same currency, should not be considered to be debt instruments containing embedded derivatives solely because of those features. This Directive should be without prejudice to any requirement in national law to register debt instruments in the issuer’s company registry for liabilities to meet the conditions for non-preferred senior class of debt instruments provided for in this Directive.
