It is expected that delivery of the Notes will be made for value on or about January 16, 2025 which will be the fifth business day in the United States following the date of pricing of the Notes. Under Rule 15c6-1 under the Securities Exchange Act of 1934, purchases or sales of Notes in the secondary market generally are required to settle within one (1) business day (T+1), unless the parties to any such transaction expressly agree otherwise. Accordingly, purchasers of the Notes who wish to trade the Notes on the date hereof or the next three (3) succeeding business days, will be required, because the Notes initially will settle within five (5) business days (T+5) in the United States, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to trade on the date hereof or the next three (3) succeeding business days should consult their own legal advisers.

MiFID II product governance / Retail investors, professional investors and eligible counterparties target market—Solely for the purposes of each EU manufacturer’s product approval process, the Underwriters’ target market assessment in respect of the Notes has led them to the conclusion that: (i) the target market for the Notes is eligible counterparties, professional clients and retail clients, each as defined in Directive 2014/65/EU (as amended, “MiFID II”) and (ii) all channels for distribution of the Notes to eligible counterparties and professional clients are appropriate; and (iii) the following channels for distribution of the Notes to retail clients are appropriate—investment advice, portfolio management, non-advised sales and pure execution services, subject to the distributor’s suitability and appropriateness obligations under MiFID II, as applicable. Any person subsequently offering, selling or recommending the Notes (a “distributor”) should take into consideration the EU manufacturers’ target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the EU manufacturers’ target market assessment) and determining appropriate distribution channels.

AIIB does not qualify as an “investment firm,” “manufacturer” or “distributor” for the purposes of MiFID II.

UK MiFIR product governance / Retail investors, professional investors and eligible counterparties target market—Solely for the purposes of each UK manufacturer’s product approval process, the Underwriters’ target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is retail clients, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (as amended, the “EUWA”), eligible counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook (“COBS”), and professional clients, as defined in Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA (“UK MiFIR”); (ii) all channels for distribution of the Notes to eligible counterparties and professional clients are appropriate; and (iii) the following channels for distribution of the Notes to retail clients are appropriate—investment advice, portfolio management, non-advised sales and pure execution services, subject to the distributor’s suitability and appropriateness obligations under COBS, as applicable. Any person subsequently offering, selling or recommending the Notes (a “distributor”) should take into consideration the UK manufacturer’s target market assessment; however, a distributor subject to the FCA Handbook Product Intervention and Product Governance Sourcebook is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the UK manufacturers’ target market assessment) and determining appropriate distribution channels.

AIIB does not qualify as an “investment firm”, “manufacturer” or “distributor” for the purposes of UK MiFIR.
