Risk Factors

Please see the Preliminary Offering Documents for a description of certain risks related to this investment, including, but not limited to, the following:

·     Depending on the performance of the Market Measure as measured shortly before the maturity date, your investment may result in a loss; there is no guaranteed return of principal.

·     Payments on the notes are subject to the credit risk of BNS, and actual or perceived changes in the creditworthiness of BNS are expected to affect the value of the notes. If BNS becomes insolvent or is unable to pay its obligations, you may lose your entire investment.

·     The initial estimated value of the notes on the pricing date will be less than their public offering price.

·     If you attempt to sell the notes prior to maturity, their market value may be lower than both the public offering price and the initial estimated value of the notes on the pricing date.

·     You will have no rights of a holder of the securities represented by the Market Measure, and you will not be entitled to receive securities or dividends or other distributions by the issuers of those securities.

·     Your return on the notes may be affected by exchange rate movements and other factors affecting the international securities markets, specifically changes in the European markets. The European markets are and have been undergoing severe financial stress, and the political, legal and regulatory ramifications are impossible to predict. Changes in the European markets could adversely affect the performance of the Market Measure and, consequently, the value of the notes.

·     A limited number of stocks included in the Market Measure may affect its level.

·     The stocks included in the Market Measure are concentrated in one sector.

·     Adverse conditions in the financial sector may reduce your return on the notes.

·     Economic conditions have adversely impacted the stock prices of many companies in the financial services sector, and may do so during the term of the notes.
