An investment in the Notes involves certain risks. For discussion of these risks, see “Risk Factors”. Investors should see, in particular, the “Terms and Conditions of the Notes” and “Taxation” in respect of procedures to be followed to receive payments under the Notes (as defined below). Noteholders are required to take affirmative action as described herein in order to receive payments on the Notes free from Portuguese withholding tax.

In this case, a statement will be includedin the applicable final terms, as to whether or not the relevant administrator of the benchmark is included in ESMA’s register of administrators under article 36 of the Benchmark Regulation. Series of Notes to be issued under the Programme will be rated or unrated. Where a Series of Notes is to be rated, such rating will not necessarily be the same as the rating assigned to any Notes already issued. In general, European regulated investors are restricted from using a rating for regulatory purposes if such rating is not issued by a credit rating agency established in the European Union and registered under Regulation (EC) No. 1060/2009, as amended (the “CRA Regulation”) and stated in the list of credit rating agencies registered with the European Securities and Market Association (“ESMA”) and published on www.esma.europa.eu, will be disclosed in the Final Terms. Any ratings ascribed to the Notes reflect only the views of Moody’s Investors Service Limited (“Moody’s”), Standard & Poor’s Credit Market Services Europe Limited (“Standard & Poor’s” or “S&P”) and Fitch Ratings Limited (“Fitch” and, together with Moody’s and Standard & Poor’s, the “Rating Agencies”). A rating is not a recommendation to buy, sell or hold securities and may be subject to suspension, change or withdrawal at any time by the assigning Rating Agency. PRIIPs/IMPORTANT – EEA RETAIL INVESTORS – If the Final Terms in respect of any Notes includes a legend entitled “Prohibition of Sales to EEA Retail Investors”, the Notes 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”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of MiFID II; or (ii) a customer within the meaning of Directive 2002/92/EC of the European Parliament and of the Council, of 9 December 2002 (as amended, the “Insurance Mediation Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Directive. Consequently, where such restriction applies, no key information document required by Regulation (EU) No 1286/2014 of the European Parliament and of the Council, of 26 November 2014 (as amended, the “PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared or will be available and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. MIFID II PRODUCT GOVERNANCE / TARGET MARKET The Final Terms in respect of any Notes will include a legend entitled “MiFID II Product Governance” which will outline the target market assessment in respect of the Notes and which channels for distribution of the Notes are appropriate. Any person subsequently offering, selling or recommending the Notes (a “distributor”) should take into consideration the target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment of end clients in respect of the Notes and determining appropriate distribution channels. A determination will be made in relation to each issue about whether, for the purpose of the MiFID II Product Governance Rules under Commission Delegated Directive (EU) 2017/593, of 7 April 2016 (the “MiFID II Product Governance Rules”), any Dealer subscribing for any Notes is a manufacturer in respect of such Notes, but otherwise, neither the Arranger nor the Dealers nor any of their respective affiliates is deemed to be a manufacturer for the purpose of the MiFID II Product Governance Rules.
