Hypothetical Payout Profile (Maturity Payment Amount)

If the securities are not automatically called prior to maturity and the Ending Price of the Lowest Performing Fund on the Final Calculation Day is less than its Downside Threshold Price, you will have full downside exposure to the decrease in the price of the Lowest Performing Fund from its Starting Price and will lose more than 30%, and possibly all, of the face amount of your securities at maturity.

Any positive return on the securities will be limited to the sum of your Contingent Coupon Payments, if any. You will not participate in any appreciation of any Fund, but you will have full downside exposure to the Lowest Performing Fund on the Final Calculation Day if the securities are not automatically called and the Ending Price of that Fund is less than its Downside Threshold Price.

The Issuer’s estimated value of the securities on the Pricing Date, based on the Issuer’s internal pricing models, is expected to be at least $900.00 per security but less than the original offering price. The estimated value of the securities is not an indication of actual profit to the Issuer or to any of the Issuer’s affiliates, nor is it an indication of the price, if any, at which Wells Fargo Securities, LLC (“Wells Fargo Securities”) or any other person may be willing to buy the securities from you at any time after issuance. See “The Estimated Value of the Securities” in the accompanying preliminary pricing supplement.
