MiFID II PRODUCT GOVERNANCE / PROFESSIONAL INVESTORS AND ECPs ONLY TARGET MARKET – Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the Bonds has led to the conclusion that: (i) the target market for the Bonds is eligible counterparties and professional clients only, each as defined in Directive 2014/65/EU of the European Parliament and of the Council on markets in financial instruments, as amended (“MiFID II”); and (ii) all channels for distribution of the Bonds to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Bonds (a “distributor”) should take into consideration the manufacturers’ target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the Bonds (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels. PROHIBITION OF SALES TO EEA AND UK RETAIL INVESTORS – The 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 European Economic Area (“EEA”) or in the United Kingdom (the “UK”). For these purposes, a retail investor means a person who is one (or both) of: (i) a retail client as defined in point (11) of MiFID II; and (ii) a customer within the meaning of Directive (EU) 2016/97 (the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II. Consequently, no key information document required by Regulation (EU) No 1286/2014 (the “PRIIPs Regulation”) for offering or selling the Bonds or otherwise making them available to retail investors in the EEA or in the UK has been prepared and therefore offering or selling the Bonds or otherwise making them available to any retail investor in the EEA or in the UK may be unlawful under the PRIIPs Regulation.
