Risk Factors: Your investment in the Notes involves certain risks, not all of which are described in this Pricing Supplement. In the consultation with your own financial and legal advisers, you should carefully consider, among other matters, the following discussion of risks (and discussion of risk contained in the Prospectus) before deciding whether an investment in the Notes is suitable for you. The Notes are not an appropriate investment for you if you are unsophisticated with respect to their significant components and interrelationships. Structure of Notes Indexed to Interest Rates: Because the Notes are indexed to the Treasury Rate, there will be significant risks not associated with a conventional fixed rate debt security. These risks include fluctuation of the interest rates and the possibility that you will receive a lower amount of interest. We have no control over a number of matters, including economic, financial and political events, that are important in determining the existence, magnitude and longevity of these risks and their results. In recent years, values of certain interest rates have been volatile, and volatility in those and other interest rates may be expected in the future. However, past experience is not necessarily indicative of what may occur in the future.
