The New Bonds are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA.

Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the "PRIIPs Regulation") for offering or selling the New Bonds or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the New Bonds or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

Consequently, no disclosure document required by the FCA Product Disclosure Sourcebook (“DISC”) for offering, selling or distributing the New Bonds or otherwise making them available to retail investors in the UK has been prepared and therefore offering, selling or distributing the New Bonds or otherwise making them available to any retail investor in the UK may be unlawful under the DISC and the Consumer Composite Investments (Designated Activities) Regulations 2024.
