Hypothetical Payout Profile***

***assumes a Call Premium equal to the lowest possible Call Premium that will be determined on the Pricing Date.

If the securities are not automatically called and the Ending Level is less than the Threshold Level, you will have 1-to-1 downside exposure to the decrease in the level of the Index in excess of 10% and will lose some, and possibly up to 90%, of the face amount of your securities at maturity.

Any positive return on the securities will be limited to the applicable Call Premium, even if the Closing Level of the Index on the applicable Call Observation Date significantly exceeds the Starting Level. You will not participate in any appreciation of the Index beyond the applicable Call Premium.

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 $927.80 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.
