Description of Terms

• Linked to the S&P 500^® Index

• Unlike ordinary debt securities, the securities do not pay interest or repay a fixed amount of principal at maturity. Instead, the securities provide for a maturity payment amount that may be greater than, equal to or less than the original offering price of the securities, depending on the performance of the Index from its starting level to its ending level. The maturity payment amount will reflect the following terms:

• If the level of the Index increases:

You will receive the original offering price plus 125% participation in the upside performance of the Index, subject to a maximum return at maturity of 12% of the original offering price. As a result of the maximum return, the maximum maturity payment amount will be $1,120.00.

• If the level of the Index decreases but the decrease is not more than 15%:

You will be repaid the original offering price

• If the level of the Index decreases by more than 15%:

You will receive less than the original offering price and have 1-to-1 downside exposure to the decrease in the level of the Index in excess of 15%

• Investors may lose up to 85% of the original offering price

• All payments on the securities are subject to credit risk, and you will have no ability to pursue any securities included in the Index for payment; if Wells Fargo Finance LLC, as issuer, and Wells Fargo & Company, as guarantor, default on their obligations, you could lose some or all of your investment

• No periodic interest payments or dividends

• No exchange listing; designed to be held to maturity

On the date of the accompanying pricing supplement, the estimated value of the securities is $970.84 per security. The estimated value of the securities was determined for the issuer by Wells Fargo Securities, LLC using its proprietary pricing models. It is not an indication of actual profit to the issuer or to Wells Fargo Securities, LLC or any of the issuer’s other affiliates, nor is it an indication of the price, if any, at which Wells Fargo Securities, LLC or any other person may be willing to buy the securities from you at any time after issuance. See “Estimated Value of the Securities” in the accompanying pricing supplement.

The securities have complex features and investing in the securities involves risks not associated with an investment in conventional debt securities. See “Selected Risk Considerations” in this term sheet and “Risk Factors” in the accompanying pricing supplement.

This final term sheet should be read in conjunction with the accompanying pricing supplement, market measure supplement, prospectus supplement and prospectus.

NOT A BANK DEPOSIT AND NOT INSURED OR GUARANTEED BY THE FDIC OR ANY OTHER GOVERNMENTAL AGENCY

How The Maturity Payment Amount Is Calculated

On the stated maturity date, you will receive a cash payment per security equal to the maturity payment amount. The maturity payment amount per security will equal:

● If the ending level is greater than the starting level: $1,000 plus the lesser of:

   (i)    

(ii) the maximum return;

● If the ending level is less than or equal to the starting level, but greater than or equal to the threshold level: $1,000; or

● If the ending level is less than the threshold level: $1,000 minus

If the ending level is less than the threshold level, you will receive less, and possibly 85% less, than the original offering price of your securities at maturity.

Selected Risk Considerations

The risks set forth below are discussed in detail in the “Risk Factors” section in the accompanying pricing supplement. Please review those risk disclosures carefully.

● If The Ending Level Is Less Than The Threshold Level, You Will Receive Less, And Possibly 85% Less, Than The Original Offering Price Of Your Securities At Maturity.

● The Securities Will Not Have The Benefit Of Any Cross-Default Or Cross-Acceleration With Other Indebtedness Of The Guarantor; Events Of Bankruptcy, Insolvency, Receivership Or Liquidation Relating To The Guarantor And Failure By The Guarantor To Perform Any Of Its Covenants Or Warranties (Other Than A Payment Default Under The Guarantee) Will Not Constitute An Event Of Default With Respect To The Securities.
