Risk Factors
(English version)
ENGLISH VERSION OF THE RISK FACTORS
The purchase of Notes may involve substantial risks and is suitable only for investors with the
knowledge and experience in financial and business matters necessary to evaluate the risks and the
merits of an investment in the Notes. Before making an investment decision, prospective purchasers of
Notes should consider carefully, in the light of their own financial circumstances and investment
objectives, all the information set forth in this Base Prospectus. Words and expressions defined in other
Parts of this Base Prospectus (including Part A "Summary of the Programme" and Part E "Terms and
Conditions of the Notes and Related Information") shall have the same meaning in this Part of the Base
Prospectus.
Prospective purchasers of the Notes should recognise that the Notes may decline in value and
should be prepared to sustain a total loss of their investment in the Notes.
Equity Linked Notes
Equity Linked Notes are debt securities which do not provide for predetermined redemption amounts
and/or interest payments. Redemption amounts and/or interest payments will depend on the market
value of the Underlying Securities which might be substantially less than the Issue Price or, as the case
may be, the purchase price invested by the Noteholder and may even be zero in which case the
Noteholder may lose his entire investment. If the Underlying Securities are to be delivered instead of
cash redemption, the value of such securities may also be substantially less than the Issue Price or, as
the case may be, the purchase price invested by the Noteholder.
Equity Linked Notes are not in any way sponsored, endorsed, sold or promoted by the issuer of the
Underlying Securities and such issuer makes no warranty or representation whatsoever express or
implied, as to the future performance of the Underlying Securities. Furthermore, the issuer of the
Underlying Securities does not assume any obligations to take the interests of the Issuer or those of the
Noteholders into consideration for any reason. None of the issuers of the Underlying Securities will
receive any of the proceeds of the offering of the Notes made hereby and is responsible for, and has
participated in, the determination of the timing of, prices for or quantities of, the Notes. The investment
in the Notes does not result in any right to receive information from the issuer of the Underlying
Securities, to exercise voting rights or to receive distributions on the Shares.
Commodity Linked Notes
Commodity Linked Notes are debt securities which do not provide for predetermined amounts and/or
interest payments. Commodity Linked Notes may relate to one or more Relevant Commodit(y)(ies) (as
defined under " Supplemental Terms and Conditions of the Notes/Certificates for Commodity Linked
Notes/Certificates") and may bear interest at commodity linked interest amounts and/or will be
redeemed at a Commodity Linked Redemption Amount, both of which will be calculated by reference
to such Relevant Commodity or the Relevant Commodities, as the case may be, as more fully set out
under "Supplemental Terms and Conditions of the Notes/Certificates for Commodity Linked
Notes/Certificates" and the Final Terms. Fluctuations in the value of the Relevant Commodity will
affect the value of the Commodity Linked Note. The amount of principal and/or interest, if any,
payable by the Issuer might be substantially less than the Issue Price or, as the case may be, the
purchase price invested by the Noteholder and may even be zero in which case the Noteholder may
lose his entire investment.
Index Linked Notes
Index Linked Notes are debt securities which do not provide for predetermined redemption amounts
and/or interest payments but amounts due in respect of principal and/or interest will be dependent upon
the performance of the Index, which itself may contain substantial credit, interest rate or other risks.
The amount of principal and/or interest, if any, payable by the Issuer might be substantially less than
the Issue Price or, as the case may be, the purchase price invested by the Noteholder and may even be
zero in which case the Noteholder may lose his entire investment.
