Market Linked Notes—Upside Participation with Quarterly Averaging and Principal Return at Maturity Notes Linked to the S&P 500^® Value Index due May 22, 2028

Investment Description

The Notes Linked to the S&P 500^® Value Index due May 22, 2028 are unsecured debt securities issued by Citigroup Global Markets Holdings Inc. and guaranteed by Citigroup Inc. Unlike conventional debt securities, the notes do not pay interest. Instead, the notes offer the potential for a positive return at maturity based on the performance of the underlying from the initial underlying value to the final average underlying value. The notes provide:

(i) the possibility of a positive return at maturity if the final average underlying value is greater than the initial underlying value; and

(ii) repayment of principal if the final average underlying value is less than or equal to the initial underlying value.

If the final average underlying value is less than or equal to the initial underlying value, you will be repaid the stated principal amount of the notes at maturity but will not receive any return on your investment. All payments on the notes are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.

The S&P 500^® Value Index is designed to measure the full performance of companies included in the S&P 500^® Index that exhibit relatively strong value characteristics (determined by reference to (1) book-value-to-price ratio, (2) earnings-to-price ratio and (3) sales-to-price ratio) and relatively weak growth characteristics (determined by reference to earnings-per-share growth, sales-per-share growth and upward share price momentum) and a portion of the performance of companies with more balanced value and growth characteristics (where greater weight is allocated to companies with relatively stronger value characteristics and relatively weaker growth characteristics).

The terms of the notes are set forth in the accompanying product supplement, prospectus supplement and prospectus, as supplemented by this pricing supplement. The accompanying product supplement, underlying supplement, prospectus supplement and prospectus contain important disclosures that are not repeated in this pricing supplement. For example, the accompanying product supplement contains important information about how the closing values of the underlying will be determined and other specified events with respect to the underlying. The accompanying underlying supplement contains information about the S&P 500^® Index, on which the underlying is ultimately based, that is not repeated in this pricing supplement. It is important that you read the accompanying product supplement, underlying supplement, prospectus supplement and prospectus together with this pricing supplement in deciding whether to invest in the notes. Certain terms used but not defined in this pricing supplement are defined in the accompanying product supplement.

When we refer to “we,” “us” and “our” in this pricing supplement, we refer only to Citigroup Global Market Holdings Inc. and not to any of its affiliates, including Citigroup Inc.

Market Linked Notes—Upside Participation with Quarterly Averaging and Principal Return at Maturity Notes Linked to the S&P 500^® Value Index due May 22, 2028

Investor Considerations

We have designed the notes for investors who:

· seek exposure to any upside performance of the underlying as measured solely by reference to an average of the closing values of the underlying on valuation dates occurring quarterly over the term of the notes, without exposure to any decline in the underlying, by:

o participating at the specified participation rate in the percentage increase, if any, from the initial underlying value to the final average underlying value; and

o providing for the repayment of the stated principal amount at maturity regardless of the performance of the underlying;

· understand that if the final average underlying value is less than or equal to the initial underlying value, they will not receive any positive return on their investment in the notes;

· are willing and able to accept the risk that the quarterly average performance of the underlying may be less than its point-to-point performance;

· are willing to forgo interest payments on the notes and dividends on the underlying; and

· are willing to hold the notes to maturity.

The notes are not designed for, and may not be a suitable investment for, investors who:

· seek a liquid investment or are unable or unwilling to hold the notes to maturity;

· seek certainty of receiving a positive return on their investment;

· seek exposure to the upside performance of the underlying as measured solely from the pricing date to a date near stated maturity, or are unwilling and unable to accept the risk that the quarterly average performance of the underlying may be less than its point-to-point performance;

· seek current income;

· are unwilling to purchase notes with an estimated value as of the pricing date that is lower than the public offering price and that may be as low as the lowest estimated value set forth on the cover page;

· are unwilling to accept the risk of exposure to the large capitalization segment of the United States equity market;

· seek exposure to the underlying but are unwilling to accept the risk/return trade-offs inherent in the payment at maturity for the notes;

· are unwilling to accept the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.; or

· prefer the lower risk of fixed income investments with comparable maturities issued by companies with comparable credit ratings.

Summary Risk Factors

An investment in the notes is significantly riskier than an investment in conventional debt securities. The notes are subject to all of the risks associated with an investment in our conventional debt securities (guaranteed by Citigroup Inc.), including the risk that we and Citigroup Inc. may default on our obligations under the notes, and are also subject to risks associated with the underlying. Accordingly, the notes are suitable only for investors who are capable of understanding the complexities and risks of the notes. You should consult your own financial, tax and legal advisors as to the risks of an investment in the notes and the suitability of the notes in light of your particular circumstances.

The following is a summary of certain key risk factors for investors in the notes. You should read this summary together with the more detailed description of risks relating to an investment in the notes contained in the section “Risk Factors Relating to the Notes” beginning on page EA-6 in the accompanying product supplement. You should also carefully read the risk factors included in the accompanying prospectus supplement and in the documents incorporated by reference in the accompanying prospectus, including Citigroup Inc.’s most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q, which describe risks relating to the business of Citigroup Inc. more generally.

You May Not Receive Any Positive Return On Your Investment In The Notes.

You will receive a positive return on your investment in the notes only if the final average underlying value is greater than the initial underlying value. If the final average underlying value is equal to or less than the initial underlying value, you will receive only the stated principal amount for each note you hold at maturity. As the notes do not pay any interest, even if the final average underlying value is greater than the initial underlying value, there is no assurance that your total return at maturity on the notes will be as great as could have been achieved on conventional debt securities of ours or of another issuer with a similar credit rating of comparable maturity.

The Notes Do Not Pay Interest.

Unlike conventional debt securities, the notes do not pay interest or any other amounts prior to maturity. You should not invest in the notes if you seek current income during the term of the notes.

The Potential For A Positive Return On The Notes At Stated Maturity Is Based On The Average Performance Of The Underlying During The Term Of The Notes, Which May Be Less Favorable Than The Performance Of The Underlying As Measured From Its Initial Underlying Value To Its Closing Value At Or Near Stated Maturity.

The potential for a positive return on the notes at stated maturity is based on the final average underlying value, which will be calculated by reference to an average of the closing values of the underlying on valuation dates occurring quarterly over the term of the notes. The final average underlying value, as so calculated, may be less than the closing value of the underlying at or near stated maturity. If the final average underlying value is less than the closing value of the underlying at or near stated maturity, the average performance of the underlying that is measured for purposes of the notes will be less favorable than the performance of the underlying as measured from its initial underlying value to its closing value at or near stated maturity, which we refer to as its “point-to-point” performance. As a result, the return on the notes may underperform the point-to-point performance of the underlying and, therefore, may underperform the return that would have been achieved on a direct investment in the underlying held over the term of the notes.

For example, if the value of the underlying increases at a more or less steady rate over the term of the notes, the final average underlying value will be less than the closing value of the underlying at or near stated maturity, and the average performance of the underlying as measured for purposes of the notes will be less than its point-to-point performance. This underperformance will be especially significant if there is a significant increase in the value of the underlying later in the term of the notes. In addition, because of the way the final average underlying value is calculated, it is possible that you will not receive any positive return on your investment at stated maturity even if the closing value of the underlying at or near stated maturity is significantly greater than the initial underlying value. One scenario in which this may occur is when the value of the underlying declines early in the term of the notes and increases significantly later in the term of the notes. You should not invest in the notes unless you understand and are willing to accept the return characteristics associated with the averaging feature of the notes.

You Will Not Receive Dividends Or Have Any Other Rights With Respect To The Underlying.

You will not receive any dividends with respect to the underlying. This lost dividend yield may be significant over the term of the notes. The payment scenarios described in this pricing supplement do not show any effect of lost dividend yield over the term of the notes. In addition, you will not have voting rights or any other rights with respect to the underlying.

PS-6

Market Linked Notes—Upside Participation with Quarterly Averaging and Principal Return at Maturity Notes Linked to the S&P 500^® Value Index due May 22, 2028

Although The Notes Provide For The Repayment Of The Stated Principal Amount At Maturity, You May Nevertheless Suffer A Loss On Your Investment In Real Value Terms If The Percentage Change From The Initial Underlying Value to the Final Average Underlying Value Is Less Than Or Not Sufficiently Greater Than Zero.

This is because inflation may cause the real value of the stated principal amount to be less at maturity than it is at the time you invest, and because an investment in the notes represents a forgone opportunity to invest in an alternative asset that does generate a positive real return. This potential loss in real value terms is significant given the term of the notes. You should carefully consider whether an investment that may not provide for any return on your investment, or may provide a return that is lower than the return on alternative investments, is appropriate for you.

The Notes Are Subject To The Credit Risk Of Citigroup Global Markets Holdings Inc. And Citigroup Inc.

If we default on our obligations under the notes and Citigroup Inc. defaults on its guarantee obligations, you may not receive anything owed to you under the notes.

The Notes Are Riskier Than Securities With A Shorter Term.

The notes are relatively long-dated. Because the notes are relatively long-dated, many of the risks of the notes are heightened as compared to securities with a shorter term, because you will be subject to those risks for a longer period of time. In addition, the value of a longer-dated security is typically less than the value of an otherwise comparable security with a shorter term.

The Notes Will Not Be Listed On Any Securities Exchange And You May Not Be Able To Sell Them Prior To Maturity.

The notes will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the notes. We have been advised that Wells Fargo currently intends to make a secondary market in relation to the notes. However, Wells Fargo may suspend or terminate making a market without notice, at any time and for any reason. If Wells Fargo suspends or terminates making a market, there may be no secondary market at all for the notes because it is likely that Wells Fargo will be the only broker-dealer that is willing to buy your notes prior to maturity. Accordingly, an investor must be prepared to hold the notes until maturity.

Sale Of The Notes Prior To Maturity May Result In A Loss Of Principal.

You will be entitled to receive at least the full stated principal amount of your notes, subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., only if you hold the notes to maturity. The value of the notes may fluctuate during the term of the notes, and if you are able to sell your notes prior to maturity, you may receive less than the full stated principal amount of your notes.

The Estimated Value Of The Notes On The Pricing Date, Based On CGMI’s Proprietary Pricing Models And Our Internal Funding Rate, Is Less Than The Public Offering Price.

The difference is attributable to certain costs associated with selling, structuring and hedging the notes that are included in the public offering price. These costs include (i) any selling concessions or other fees paid in connection with the offering of the notes, (ii) hedging and other costs incurred by us and our affiliates in connection with the offering of the notes and (iii) the expected profit (which may be more or less than actual profit) to CGMI or other of our affiliates and/or Wells Fargo or its affiliates in connection with hedging our obligations under the notes. These costs adversely affect the economic terms of the notes because, if they were lower, the economic terms of the notes would be more favorable to you. The economic terms of the notes are also likely to be adversely affected by the use of our internal funding rate, rather than our secondary market rate, to price the notes. See “The Estimated Value Of The Notes Would Be Lower If It Were Calculated Based On Well’s Fargo’s Determination Of The Secondary Market Rate With Respect To Us” below.

The Estimated Value Of The Notes Was Determined For Us By Our Affiliate Using Proprietary Pricing Models.

CGMI derived the estimated value disclosed on the cover page of this pricing supplement from its proprietary pricing models. In doing so, it may have made discretionary judgments about the inputs to its models, such as the volatility in the closing value of the underlying, the dividend yields on the underlying and interest rates. CGMI’s views on these inputs may differ from your or others’ views, and as an underwriter in this offering, CGMI’s interests may conflict with yours. Both the models and the inputs to the models may prove to be wrong and therefore not an accurate reflection of the value of the notes. Moreover, the estimated value of the notes set forth on the cover page of this pricing supplement may differ from the value that we or our affiliates may determine for the notes for other purposes, including for accounting purposes. You should not invest in the notes because of the estimated value of the notes. Instead, you should be willing to hold the notes to maturity irrespective of the initial estimated value.

PS-7

Market Linked Notes—Upside Participation with Quarterly Averaging and Principal Return at Maturity Notes Linked to the S&P 500^® Value Index due May 22, 2028

The Estimated Value Of The Notes Would Be Lower If It Were Calculated Based On Wells Fargo’s Determination Of The Secondary Market Rate With Respect To Us.

The estimated value of the notes included in this pricing supplement is calculated based on our internal funding rate, which is the rate at which we are willing to borrow funds through the issuance of the notes. We expect that our internal funding rate is generally lower than Wells Fargo’s determination of the secondary market rate with respect to us, which is the rate that we expect Wells Fargo will use in determining the value of the notes for purposes of any purchases of the notes from you in the secondary market. If the estimated value included in this pricing supplement were based on Wells Fargo’s determination of the secondary market rate with respect to us, rather than our internal funding rate, it would likely be lower. We determine our internal funding rate based on factors such as the costs associated with the notes, which are generally higher than the costs associated with conventional debt securities, and our liquidity needs and preferences. Our internal funding rate is not an interest rate that is payable on the notes.

Because there is not an active market for traded instruments referencing our outstanding debt obligations, Wells Fargo may determine the secondary market rate with respect to us for purposes of any purchase of the notes from you in the secondary market based on the market price of traded instruments referencing the debt obligations of Citigroup Inc., our parent company and the guarantor of all payments due on the notes, but subject to adjustments that Wells Fargo may deem appropriate.

The Estimated Value Of The Notes Is Not An Indication Of The Price, If Any, At Which Any Person May Be Willing To Buy The Notes From You In The Secondary Market.

Any such secondary market price will fluctuate over the term of the notes based on the market and other factors described in the next risk factor. Moreover, unlike the estimated value included in this pricing supplement, we expect that any value of the notes determined for purposes of a secondary market transaction will be based on Wells Fargo’s determination of the secondary market rate with respect to us, which will likely result in a lower value for the notes than if our internal funding rate were used. In addition, we expect that any secondary market price for the notes will be reduced by a bid-ask spread, which may vary depending on the aggregate stated principal amount of the notes to be purchased in the secondary market transaction, and may be reduced by the expected cost of unwinding related hedging transactions. As a result, it is likely that any secondary market price for the notes will be less than the public offering price.

The Value Of The Notes Prior To Maturity Will Fluctuate Based On Many Unpredictable Factors.

The value of your notes prior to maturity will fluctuate based on the value of the underlying, the volatility in the closing value of the underlying, the dividend yield on the underlying, interest rates generally, the time remaining to maturity and our and Citigroup Inc.’s creditworthiness, as reflected in our secondary market rate, among other factors described under “Risk Factors Relating to the Notes—Risk Factors Relating to All Notes—The value of your notes prior to maturity will fluctuate based on many unpredictable factors” in the accompanying product supplement. Changes in the value of the underlying may not result in a comparable change in the value of your notes. You should understand that the value of your notes at any time prior to maturity may be significantly less than the public offering price.

We Have Been Advised That, Immediately Following Issuance, Any Secondary Market Bid Price Provided By Wells Fargo, And The Value That Will Be Indicated On Any Brokerage Account Statements Prepared By Wells Fargo Or Its Affiliates, Will Reflect A Temporary Upward Adjustment.

The amount of this temporary upward adjustment will steadily decline to zero over the temporary adjustment period. See “Valuation of the Notes” in this pricing supplement.

The Investment Strategy Represented By The Underlying May Not Be Successful.

The underlying is designed to measure the full performance of companies included in the S&P 500^® Index that exhibit relatively strong value characteristics (determined by reference to (1) book-value-to-price ratio, (2) earnings-to-price ratio and (3) sales-to-price ratio) and relatively weak growth characteristics (determined by reference to earnings-per-share growth, sales-per-share growth and upward share price momentum) and a portion of the performance of companies with more balanced value and growth characteristics (where greater weight is allocated to companies with relatively stronger value characteristics and relatively weaker growth characteristics). For additional information about the methodology used to determine the composition of the underlying, see “Annex — The S&P 500^® Value Index” in this pricing supplement. There is, however, no assurance that the underlying will outperform any other index or strategy that tracks U.S. stocks selected using other criteria. A “value” investment strategy is premised on the goal of investing in stocks that are determined to be relatively cheap or “undervalued” under the assumption that the value of those stocks will increase over time as the market comes to reflect the “fair” market value of those stocks. However, the value characteristic referenced by the underlying may not be accurate predictors of undervalued stocks, and there is no guarantee that undervalued stocks will appreciate. In addition, the underlying’s selection methodology includes a significant bias against stocks with strong growth

PS-8

Market Linked Notes—Upside Participation with Quarterly Averaging and Principal Return at Maturity Notes Linked to the S&P 500^® Value Index due May 22, 2028

characteristics, and stocks with strong growth characteristics might outperform stocks with weak growth characteristics. It is possible that the stock selection methodology of the underlying will adversely affect its return and, consequently, the values of the underlying and the notes.

The Underlying Reflects The Price Return Of The Securities Composing The Underlying, Not The Total Return.

The return on the notes is based on the performance of the underlying, which reflects changes in the market prices of the securities composing the underlying. The underlying is not a “total return” index that, in addition to reflecting those price returns, would also reflect dividends paid on the securities composing the underlying. Accordingly, the return on the notes will not include such a total return feature.

Our Offering Of The Notes Is Not A Recommendation Of The Underlying.

The fact that we are offering the notes does not mean that we or Wells Fargo or its affiliates believe that investing in an instrument linked to the underlying is likely to achieve favorable returns. In fact, as we and Wells Fargo and its affiliates are each part of respective global financial institutions, our affiliates and affiliates of Wells Fargo may have positions (including short positions) in the underlying or in instruments related to the underlying, and may publish research or express opinions, that in each case are inconsistent with an investment linked to the underlying. These and other activities of our affiliates or of Wells Fargo or its affiliates may affect the closing values of the underlying in a way that negatively affects the value of and your return on the notes.

The Closing Value Of The Underlying May Be Adversely Affected By Our Or Our Affiliates’, Or By Wells Fargo And Its Affiliates’, Hedging And Other Trading Activities.

We expect to hedge our obligations under the notes through CGMI or other of our affiliates and/or Wells Fargo or its affiliates, who may take positions in the underlying or in financial instruments related to the underlying and may adjust such positions during the term of the notes. Our affiliates and Wells Fargo and its affiliates may also take positions in the underlying or in financial instruments related to the underlying on a regular basis (taking long or short positions or both), for their accounts, for other accounts under their management or to facilitate transactions on behalf of customers. These activities could affect the closing values of the underlying in a way that negatively affects the value of and your return on the notes. They could also result in substantial returns for us or our affiliates or Wells Fargo and its affiliates while the value of the notes declines.

We And Our Affiliates And Wells Fargo And Its Affiliates May Have Economic Interests That Are Adverse To Yours As A Result Of Our And Their Respective Business Activities.

Our affiliates and Wells Fargo and its affiliates engage in business activities with a wide range of companies. These activities include extending loans, making and facilitating investments, underwriting securities offerings and providing advisory services. These activities could involve or affect the underlying in a way that negatively affects the value of and your return on the notes. They could also result in substantial returns for us or our affiliates or Wells Fargo or its affiliates while the value of the notes declines. In addition, in the course of this business, we or our affiliates or Wells Fargo or its affiliates may acquire non-public information, which will not be disclosed to you.

The Calculation Agent, Which Is An Affiliate Of Ours, Will Make Important Determinations With Respect To The Notes.

If certain events occur during the term of the notes, such as market disruption events and other events with respect to the underlying, CGMI, as calculation agent, will be required to make discretionary judgments that could significantly affect your return on the notes. In making these judgments, the calculation agent’s interests as an affiliate of ours could be adverse to your interests as a holder of the notes. See “Risk Factors Relating to the Notes—Risk Factors Relating to All Notes—The calculation agent, which is an affiliate of ours, will make important determinations with respect to the notes” in the accompanying product supplement.

Changes That Affect The Underlying May Affect The Value Of Your Notes.

The sponsor of the underlying may at any time make methodological changes or other changes in the manner in which they operate that could affect the values of the underlying. We are not affiliated with the underlying sponsor and, accordingly, we have no control over any changes the sponsor may make. Such changes could adversely affect the performance of the underlying and the value of and your return on the notes.

The Stated Maturity Date May Be Postponed If The Final Valuation Date Is Postponed.

A valuation date (including the final valuation date) will be postponed if the applicable originally scheduled valuation date is not a trading day with respect to the underlying or if the calculation agent determines that a market disruption event has occurred or is

continuing on that valuation date. If such a postponement occurs with respect to the final valuation date, the stated maturity date will be the later of (i) the initial stated maturity date and (ii) three business days after the final valuation date as postponed.

You Will Be Required To Recognize Taxable Income On The Notes Prior To Maturity.

If you are a U.S. holder of a note, you will be required to recognize taxable interest income in each year that you hold the note, even though you will not receive any payment in respect of the note prior to maturity (or earlier sale, exchange or retirement). In addition, any gain you recognize will be treated as ordinary interest income rather than capital gain. You should review the section of this pricing supplement entitled “United States Federal Tax Considerations.”

Hypothetical Returns

The table below is based on a range of hypothetical percentage changes from the initial underlying value to the hypothetical final average underlying value and illustrates:

• the hypothetical percentage change from the initial underlying value to the hypothetical final average underlying value;

• the hypothetical payment at maturity per note; and

• the hypothetical total pre-tax rate of return.

The table below is based on a hypothetical initial underlying value of 100 and does not reflect the actual initial underlying value. The table below assumes that the participation rate will be set at the lowest value indicated in “Terms of the Notes” above. The actual participation rate will be determined on the pricing date.

Hypothetical final average underlying value	Hypothetical percentage change from the initial underlying value to the hypothetical final average underlying value	Hypothetical payment at maturity per note	Hypothetical total pre-tax rate of return

Hypothetical Examples

The examples below illustrate how to determine the payment at maturity on the notes, assuming the various hypothetical final average underlying values indicated below. The examples are solely for illustrative purposes, do not show all possible outcomes and are not a prediction of what the actual payment at maturity on the notes will be. The actual payment at maturity will depend on the actual final average underlying value.

The examples below are based on a hypothetical initial underlying value of 100, rather than the actual initial underlying value. For the actual initial underlying value, see “Terms of the Notes” above. We have used this hypothetical value, rather than the actual value, to simplify the calculations and aid understanding of how the notes work. However, you should understand that the actual payment at maturity on the notes will be calculated based on the actual initial underlying value, and not the hypothetical value used in the examples below. The examples below assume that the participation rate will be set at the lowest value indicated in “Terms of the Notes” above. The actual participation rate will be determined on the pricing date.

Example 1—The underlying generally appreciates earlier in the term of the notes and depreciates later in the term of the notes, and the hypothetical final average underlying value is 102.45, which is greater than the hypothetical initial underlying value.

Payment at maturity per note = $1,000 + [$1,000 × final average underlying value – initial underlying value × participation rate]
initial underlying value

= $1,000 + ($1,000 × 102.45 – 100 × participation rate)

                                           100

= $1,000 + ($1,000 × 2.45% × 100%)

= $1,000 + $24.50

= $1,024.50

Because the final average underlying value is greater than the hypothetical initial underlying value, you would receive a total return at maturity equal to the percentage change from the hypothetical initial underlying value to the hypothetical final average underlying value multiplied by the participation rate. This example illustrates a scenario in which the averaging feature results in a greater return at maturity than a return based solely on the closing value of the underlying on a date near maturity. In this scenario, the closing value of the underlying increases early in the term of the notes, remains consistently above the initial underlying value for a significant period of time and then decreases to a value below the final average underlying value near maturity of the notes. Note that, as Examples 2 and 3 illustrate, there are other scenarios in which the averaging approach would result in a lower return at maturity.

PS-12

Market Linked Notes—Upside Participation with Quarterly Averaging and Principal Return at Maturity Notes Linked to the S&P 500^® Value Index due May 22, 2028

Example 2—The underlying generally depreciates earlier in the term of the notes and appreciates later in the term of the notes, and the hypothetical final average underlying value is 92.73, which is less than the hypothetical initial underlying value.

Payment at maturity per note = $1,000

Because the hypothetical final average underlying value is less than the initial underlying value, you would be repaid the stated principal amount of your notes at maturity but would not receive any positive return on your investment. This example illustrates a scenario in which the averaging feature results in no positive return at maturity even though the closing value of the underlying on a date near maturity is greater than the initial underlying value. In this scenario, the closing value of the underlying decreases early in the term of the notes, remains consistently below the initial underlying value for a significant period of time and then increases later in the term of the notes.

PS-13

Market Linked Notes—Upside Participation with Quarterly Averaging and Principal Return at Maturity Notes Linked to the S&P 500^® Value Index due May 22, 2028

Example 3—The underlying generally appreciates over the term of the notes, and the hypothetical final average underlying value is 130.75, which is greater than the hypothetical initial underlying value.

Payment at maturity per note = $1,000 + [$1,000 × final average underlying value – initial underlying value × participation rate]
initial underlying value

= $1,000 + ($1,000 × 130.75 – 100 × participation rate)
                                           100

= $1,000 + ($1,000 × 30.75% × 100%)

= $1,000 + $307.50

= $1,307.50

Because the final average underlying value is greater than the hypothetical initial underlying value, you would receive a total return at maturity equal to the percentage change from the hypothetical initial underlying value to the hypothetical final average underlying value multiplied by the participation rate. This example illustrates a scenario in which the averaging feature results in a lower return at maturity than a return based solely on the closing value of the underlying on a date near maturity. In this scenario, the closing value of the underlying steadily increases over the term of the notes, resulting in a closing value near maturity that is greater than the final average underlying value.

Example 4—The underlying generally depreciates over the term of the notes, and the hypothetical final average underlying value is 71.10, which is less than the hypothetical initial underlying value.

Payment at maturity per note = $1,000

Because the hypothetical final average underlying value is less than the initial underlying value, you would be repaid the stated principal amount of your notes at maturity but would not receive any positive return on your investment. This example illustrates that the notes provide for the repayment of the stated principal amount of at maturity even in scenarios in which the final average underlying value of the underlying is less than the initial underlying value.

To the extent that the final average underlying value, initial underlying value and participation rate differ from the values assumed above, the results indicated above would be different.

Additional Terms of the Notes

The following provisions supersede the provisions in the product supplement to the extent that they are inconsistent from those provisions.

Certain Definitions

The “closing value” of the underlying on any day is its closing level on that day, as the term “closing level” is defined in the accompanying product supplement.

A “trading day” means a day, as determined by the calculation agent, on which (i) the relevant stock exchanges with respect to each security underlying the underlying are scheduled to be open for trading for their respective regular trading sessions and (ii) each related futures or options exchange with respect to the underlying is scheduled to be open for trading for its regular trading session.

The “relevant stock exchange” for any security underlying the underlying means the primary exchange or quotation system on which such security is traded, as determined by the calculation agent.

The “related futures or options exchange” for the underlying means an exchange or quotation system where trading has a material effect (as determined by the calculation agent) on the overall market for futures or options contracts relating to the underlying.

Postponement of a Valuation Date

If any scheduled valuation date is not a trading day, such valuation date will be postponed to the next succeeding day that is a trading day. A valuation date is also subject to postponement due to the occurrence of a market disruption event. See “—Market Disruption Events.”

Market Disruption Events

A “market disruption event” with respect to the underlying means any of the following events as determined by the calculation agent in its sole discretion:

(A) The occurrence or existence of a material suspension of or limitation imposed on trading by the relevant stock exchanges or otherwise relating to securities which then comprise 20% or more of the level of the underlying or any successor index at any time during the one-hour period that ends at the close of trading on that day, whether by reason of movements in price exceeding limits permitted by those relevant stock exchanges or otherwise.

(B) The occurrence or existence of a material suspension of or limitation imposed on trading by any related futures or options exchange or otherwise in futures or options contracts relating to the underlying or any successor index on any related futures or options exchange at any time during the one-hour period that ends at the close of trading on that day, whether by reason of movements in price exceeding limits permitted by the related futures or options exchange or otherwise.

(C) The occurrence or existence of any event, other than an early closure, that materially disrupts or impairs the ability of market participants in general to effect transactions in, or obtain market values for, securities that then comprise 20% or more of the level of the underlying or any successor index on their relevant stock exchanges at any time during the one-hour period that ends at the close of trading on that day.

(D) The occurrence or existence of any event, other than an early closure, that materially disrupts or impairs the ability of market participants in general to effect transactions in, or obtain market values for, futures or options contracts relating to the underlying or any successor index on any related futures or options exchange at any time during the one-hour period that ends at the close of trading on that day.

(E) The closure on any exchange business day of the relevant stock exchanges on which securities that then comprise 20% or more of the level of the underlying or any successor index are traded or any related futures or options exchange with respect

PS-16

Market Linked Notes—Upside Participation with Quarterly Averaging and Principal Return at Maturity Notes Linked to the S&P 500^® Value Index due May 22, 2028

to the underlying or any successor index prior to its scheduled closing time unless the earlier closing time is announced by the relevant stock exchange or related futures or options exchange, as applicable, at least one hour prior to the earlier of (1) the actual closing time for the regular trading session on such relevant stock exchange or related futures or options exchange, as applicable, and (2) the submission deadline for orders to be entered into the relevant stock exchange or related futures or options exchange, as applicable, system for execution at such actual closing time on that day.

(F) The relevant stock exchange for any security underlying the underlying or successor index or any related futures or options exchange with respect to the underlying or successor index fails to open for trading during its regular trading session.

For purposes of determining whether a market disruption event has occurred:

(1) the relevant percentage contribution of a security to the level of the underlying or any successor index will be based on a comparison of (x) the portion of the level of the underlying attributable to that security and (y) the overall level of the underlying or successor index, in each case immediately before the occurrence of the market disruption event;

(2) the “close of trading” on any trading day for the underlying or any successor index means the scheduled closing time of the relevant stock exchanges with respect to the securities underlying the underlying or successor index on such trading day; provided that, if the actual closing time of the regular trading session of any such relevant stock exchange is earlier than its scheduled closing time on such trading day, then (x) for purposes of clauses (A) and (C) of the definition of “market disruption event” above, with respect to any security underlying the underlying or successor index for which such relevant stock exchange is its relevant stock exchange, the “close of trading” means such actual closing time and (y) for purposes of clauses (B) and (D) of the definition of “market disruption event” above, with respect to any futures or options contract relating to the underlying or successor index, the “close of trading” means the latest actual closing time of the regular trading session of any of the relevant stock exchanges, but in no event later than the scheduled closing time of the relevant stock exchanges;

(3) the “scheduled closing time” of any relevant stock exchange or related futures or options exchange on any trading day for the underlying or any successor index means the scheduled weekday closing time of such relevant stock exchange or related futures or options exchange on such trading day, without regard to after hours or any other trading outside the regular trading session hours; and

(4) an “exchange business day” means any trading day for the underlying or any successor index on which each relevant stock exchange for the securities underlying the underlying or any successor index and each related futures or options exchange with respect to the underlying or any successor index are open for trading during their respective regular trading sessions, notwithstanding any such relevant stock exchange or related futures or options exchange closing prior to its scheduled closing time.

If a market disruption event occurs or is continuing on any valuation date, then such valuation date will be postponed to the first succeeding trading day on which a market disruption event has not occurred and is not continuing; however, if such first succeeding trading day has not occurred as of the eighth trading day after the originally scheduled valuation date, that eighth trading day shall be deemed to be the valuation date. If a valuation date has been postponed eight trading days after the originally scheduled valuation date and a market disruption event occurs or is continuing on such eighth trading day, the calculation agent will determine the closing value of the underlying on such eighth trading day in accordance with the formula for and method of calculating the closing value of the underlying last in effect prior to commencement of the market disruption event, using the closing price (or, with respect to any relevant security, if a market disruption event has occurred with respect to such security, its good faith estimate of the value of such security at the scheduled closing time of the relevant stock exchange for such security or, if earlier, the actual closing time of the regular trading session of such relevant stock exchange) on such date of each security included in the underlying. As used herein, “closing price” means, with respect to any security on any date, the relevant stock exchange traded or quoted price of such security as of the scheduled closing time of the relevant stock exchange for such security or, if earlier, the actual closing time of the regular trading session of such relevant stock exchange.

United States Federal Tax Considerations

In the opinion of our counsel, Davis Polk & Wardwell LLP, the notes will be treated as “contingent payment debt instruments” for U.S. federal income tax purposes, as described in the section of the accompanying product supplement called “United States Federal Tax Considerations—Tax Consequences to U.S. Holders—Notes Treated as Contingent Payment Debt Instruments,” and the remaining discussion is based on this treatment. The discussion herein does not address the consequences to taxpayers subject to special tax accounting rules under Section 451(b) of the Internal Revenue Code of 1986, as amended (the “Code”).

If you are a U.S. Holder (as defined in the accompanying product supplement), you will be required to recognize interest income during the term of the notes at the “comparable yield,” which generally is the yield at which we could issue a fixed-rate debt instrument with terms similar to those of the notes, including the level of subordination, term, timing of payments and general market conditions, but excluding any adjustments for the riskiness of the contingencies or the liquidity of the notes. We are required to construct a “projected payment schedule” in respect of the notes representing a payment the amount and timing of which would produce a yield to maturity on the notes equal to the comparable yield. Assuming you hold the notes until their maturity, the amount of interest you include in income based on the comparable yield in the taxable year in which the notes mature will be adjusted upward or downward to reflect the difference, if any, between the actual and projected payment on the notes at maturity as determined under the projected payment schedule. However, special rules may apply if the payment at maturity on the notes is treated as becoming fixed prior to maturity. See “United States Federal Tax Considerations—Tax Consequences to U.S. Holders—Notes Treated as Contingent Payment Debt Instruments” in the accompanying product supplement for a more detailed discussion of the special rules.

Upon the sale, exchange or retirement of the notes prior to maturity, you generally will recognize gain or loss equal to the difference between the proceeds received and your adjusted tax basis in the notes. Your adjusted tax basis will equal your purchase price for the notes, increased by interest previously included in income on the notes. Any gain generally will be treated as ordinary income, and any loss generally will be treated as ordinary loss to the extent of prior interest inclusions on the note and as capital loss thereafter.

We have determined that the comparable yield for a note is a rate of  %, compounded semi-annually, and that the projected payment schedule with respect to a note consists of a single payment of $ at maturity.

Neither the comparable yield nor the projected payment schedule constitutes a representation by us regarding the actual amount that we will pay on the notes.

Non-U.S. Holders. Subject to the discussions below regarding Section 871(m) and in “United States Federal Tax Considerations—Tax Consequences to Non-U.S. Holders” and “—FATCA” in the accompanying product supplement, if you are a Non-U.S. Holder (as defined in the accompanying product supplement) of the notes, under current law you generally will not be subject to U.S. federal withholding or income tax in respect of any payment on or any amount received on the sale, exchange or retirement of the notes, provided that (i) income in respect of the notes is not effectively connected with your conduct of a trade or business in the United States, and (ii) you comply with the applicable certification requirements. See “United States Federal Tax Considerations—Tax Consequences to Non-U.S. Holders” in the accompanying product supplement for a more detailed discussion of the rules applicable to Non-U.S. Holders of the notes.

As discussed under “United States Federal Tax Considerations—Tax Consequences to Non-U.S. Holders—Possible Withholding Under Section 871(m) of the Code” in the accompanying product supplement, Section 871(m) of the Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities (“U.S. Underlying Equities”) or indices that include U.S. Underlying Equities. Section 871(m) generally applies to instruments that substantially replicate the economic performance of one or more U.S. Underlying Equities, as determined based on tests set forth in the applicable Treasury regulations. However, the regulations, as modified by an Internal Revenue Service (“IRS”) notice, exempt financial instruments issued prior to January 1, 2023 that do not have a “delta” of one. Based on the terms of the notes and representations provided by us as of the date of this preliminary pricing supplement, our counsel is of the opinion that the notes should not be treated as transactions that have a “delta” of one within the meaning of the regulations with respect to any U.S. Underlying Equity and, therefore, should not be subject to withholding tax under Section 871(m). However, the final determination regarding the treatment of the notes under Section 871(m) will be made as of the pricing date for the notes, and it is possible that the notes will be subject to withholding under Section 871(m) based on the circumstances as of that date.

A determination that the notes are not subject to Section 871(m) is not binding on the IRS, and the IRS may disagree with this treatment. Moreover, Section 871(m) is complex and its application may depend on your particular circumstances, including your other transactions. You should consult your tax adviser regarding the potential application of Section 871(m) to the notes.

PS-19

If withholding tax applies to the notes, we will not be required to pay any additional amounts with respect to amounts withheld.

You should read the section entitled “United States Federal Tax Considerations” in the accompanying product supplement. The preceding discussion, when read in combination with that section, constitutes the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of owning and disposing of the notes.

You should also consult your tax adviser regarding all aspects of the U.S. federal tax consequences of an investment in the notes and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Supplemental Plan of Distribution

Pursuant to the terms of the Amended and Restated Global Selling Agency Agreement, dated April 7, 2017, CGMI, acting as principal, will purchase the notes from Citigroup Global Markets Holdings Inc. CGMI, as the lead agent for the offering, expects to sell the notes to Wells Fargo, as agent. Wells Fargo will receive an underwriting discount and commission of up to 4.95% ($49.50) for each note it sells. Wells Fargo will pay selected dealers, which may include WFA, a fixed selling commission of 2.50% ($25.00) for each note they sell. In addition to the selling commission allowed to WFA, Wells Fargo will pay $1.20 per note of the underwriting discount and commission to WFA as a distribution expense fee for each note sold by WFA.

The public offering price of the notes includes the underwriting discount and commission described on the cover page of this pricing supplement and the estimated cost of hedging our obligations under the notes. We expect to hedge our obligations under the notes through affiliated or unaffiliated counterparties, which may include our affiliates or affiliates of Wells Fargo. Our cost of hedging will include the projected profit that such counterparties, which may include our affiliates and affiliates of Wells Fargo, expect to realize in consideration for assuming the risks inherent in hedging our obligations under the notes. Because hedging our obligations entails risks and may be influenced by market forces beyond the control of any counterparty, which may include our affiliates and affiliates of Wells Fargo, such hedging may result in a profit that is more or less than expected, or could result in a loss.

This pricing supplement and the accompanying product supplement, underlying supplement, prospectus supplement and prospectus may be used by Wells Fargo or an affiliate of Wells Fargo in connection with offers and sales related to market-making or other transactions in the notes. Wells Fargo or an affiliate of Wells Fargo may act as principal or agent in such transactions. Such sales will be made at prices related to prevailing market prices at the time of sale or otherwise.

No action has been or will be taken by Citigroup Global Markets Holdings Inc., Wells Fargo or any broker-dealer affiliates of any of them that would permit a public offering of the notes or possession or distribution of this pricing supplement or the accompanying product supplement, underlying supplement, prospectus supplement or prospectus in any jurisdiction, other than the United States, where action for that purpose is required. No offers, sales or deliveries of the notes, or distribution of this pricing supplement, the accompanying product supplement, underlying supplement or prospectus supplement and prospectus, may be made in or from any jurisdiction except in circumstances that will result in compliance with any applicable laws and regulations and will not impose any obligations on Citigroup Global Markets Holdings Inc., Wells Fargo or any broker-dealer affiliates of any of them.

For the following jurisdictions, please note specifically:

Argentina

Citigroup Global Markets Holdings Inc.’s Series N Medium-Term Senior Notes program and the related offer of the notes and the sale of the notes under the terms and conditions provided herein does not constitute a public offering in Argentina.

Paraguay

This is a private and personal offering. The notes offered have not been approved by or registered with the National Securities Commission (Comisión Nacional de Valores) and are not part of a public offering as defined by the Paraguayan Securities Law. The information contained herein is for informational and marketing purposes only and should not be taken as an investment advice.

Peru

The notes have not been and will not be registered with the Capital Markets Public Registry of the Capital Markets Superintendence (SMV) nor the Lima Stock Exchange Registry (RBVL) for their public offering in Peru under the Peruvian Capital Markets Law (Law N°861/ Supreme Decree N°093-2002) and the decrees and regulations thereunder.

Consequently, the notes may not be offered or sold, directly or indirectly, nor may this pricing supplement and the accompanying product supplement, underlying supplement, prospectus supplement and prospectus or any other offering material relating to the notes be distributed or caused to be distributed in Peru to the general public. The notes may only be offered in a private offering without using mass marketing, which is defined as a marketing strategy utilizing mass distribution and mass media to offer, negotiate or distribute notes to the whole market. Mass media includes newspapers, magazines, radio, television, mail, meetings, social networks, Internet servers located in Peru, and other media or technology platforms.

Taiwan

These notes may be made available outside Taiwan for purchase by Taiwan residents outside Taiwan but may not be offered or sold in Taiwan.

Valuation of the Notes

CGMI calculated the estimated value of the notes set forth on the cover page of this pricing supplement based on proprietary pricing models. CGMI’s proprietary pricing models generated an estimated value for the notes by estimating the value of a hypothetical package of financial instruments that would replicate the payout on the notes, which consists of a fixed-income bond (the “bond component”) and one or more derivative instruments underlying the economic terms of the notes (the “derivative component”). CGMI calculated the estimated value of the bond component using a discount rate based on our internal funding rate. CGMI calculated the estimated value of the derivative component based on a proprietary derivative-pricing model, which generated a theoretical price for the instruments that constitute the derivative component based on various inputs, including the factors described under “Summary Risk Factors—The Value Of The Notes Prior To Maturity Will Fluctuate Based On Many Unpredictable Factors” in this pricing supplement, but not including our or Citigroup Inc.’s creditworthiness. These inputs may be market-observable or may be based on assumptions made by CGMI in its discretionary judgment.

The estimated value of the notes is a function of the terms of the notes and the inputs to CGMI’s proprietary pricing models. As of the date of this preliminary pricing supplement, it is uncertain what the estimated value of the notes will be on the pricing date because certain terms of the notes have not yet been fixed and because it is uncertain what the values of the inputs to CGMI’s proprietary pricing models will be on the pricing date.

We have been advised that, for a period of approximately six months following issuance of the notes, the price, if any, at which Wells Fargo would be willing to buy the notes from investors, and the value that will be indicated for the notes on any brokerage account statements prepared by Wells Fargo or its affiliates, will reflect a temporary upward adjustment from the price or value that would otherwise be determined. This temporary upward adjustment represents a portion of the costs associated with selling, structuring and hedging the notes that are included in the public offering price of the notes. The amount of this temporary upward adjustment will decline to zero on a straight-line basis over the six-month temporary adjustment period. However, Wells Fargo is not obligated to buy the notes from investors at any time. See “Summary Risk Factors—The Notes Will Not Be Listed On Any Securities Exchange And You May Not Be Able To Sell Them Prior To Maturity.”

Market Linked Notes—Upside Participation with Quarterly Averaging and Principal Return at Maturity Notes Linked to the S&P 500^® Value Index due May 22, 2028

Annex — The S&P 500^® Value Index

We have derived all information contained in this pricing supplement regarding the underlying, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, S&P Dow Jones Indices LLC (“S&P Dow Jones”). The underlying is calculated, maintained and published by S&P Dow Jones. S&P Dow Jones has no obligation to continue to publish, and may discontinue the publication of, the underlying.

The underlying is reported by Bloomberg, L.P. under the ticker symbol “SVX.”

The underlying is a subset of the S&P 500^® Index and is a float-adjusted market-capitalization weighted index. S&P Dow Jones allocates the complete float-adjusted market capitalization of the companies included in the S&P 500^® Index between the underlying and the S&P 500^® Growth Index (the “Growth Index”) based on an assessment of those companies’ respective value and growth characteristics. The market capitalization of companies exhibiting the strongest value characteristics relative to their respective growth characteristics is allocated to the underlying (approximately 33% of the market capitalization of the S&P 500^® Index), and the market capitalization of companies exhibiting the strongest growth characteristics relative to their respective value characteristics (approximately 33% of the market capitalization of the S&P 500^® Index) is allocated to the Growth Index. The market capitalization of the remaining companies included in the S&P 500^® Index is split between the underlying and the Growth Index, with more of the market capitalization of companies exhibiting stronger value characteristics relative to their respective growth characteristics being allocated to the underlying and more of the market capitalization of companies exhibiting the stronger growth characteristics relative to their respective value characteristics being allocated to the Growth Index.

The S&P 500^® Index consists of stocks of 500 companies selected to provide a performance benchmark for the U.S. equity markets. For more information about the S&P 500^® Index, see “Equity Index Descriptions—The S&P U.S. Indices” in the accompanying underlying supplement.

Underlying Construction

The underlying is derived from its parent index, the S&P 500^® Index. The underlying cannot have a constituent that is not also a member of the S&P 500^® Index.

Style Factors. The Growth Index and the underlying (the “Style Indices”) measure growth and value along two separate dimensions, with three factors each used to measure growth and value. The list of factors used is outlined in the table below.

Growth Factors	Value Factors
Three-year change in earnings per share (excluding extra items) over price per share	Book value to price ratio
Three-year sales per share growth rate	Earnings to price ratio
Momentum (12-month % price change)	Sales to price ratio

· If earnings from three years prior are not available, two-year change in earnings per share (excluding extra items) over price per share is used. If earnings from two years prior are not available, one-year change in earnings per share (excluding extra items) over price per share is used. If earnings from one year prior are not available, the factor is set equal to zero. If the starting values is less than zero, the score is multiplied by a factor of negative 1.

· If sales from three years prior are not available, two-year sales per share growth rate is used. If sales from two years prior are not available, one-year sales per share growth rate is used. If sales from one year prior are not available, the factor is set equal to zero. If the starting values is less than zero, the score is multiplied by a factor of negative 1.

· If there is not enough trading history to calculate 12-month momentum then the momentum factor is calculated from the stock’s listing date.

· If book value to price ratio, earnings to price ratio, or sales to price ratio is not available then such factor is set equal to zero.

Market Linked Notes—Upside Participation with Quarterly Averaging and Principal Return at Maturity Notes Linked to the S&P 500^® Value Index due May 22, 2028

Style Scores. Raw values for each of the above factors are calculated by S&P Dow Jones for each company in the S&P Total Market Index universe. The S&P Total Market Index is a float-adjusted, market-capitalization weighted index designed to track the broad U.S. equity market, including large-, mid-, small- and micro-cap stocks.

These raw values are first “winsorized” (a statistical tool used to minimize the influence of outliers in data) to the 90^th percentile and then standardized by dividing the difference between each company’s raw score and the mean of the entire set by the standard deviation of the entire set. A “growth score” for each company is computed as the average of the standardized values of the three growth factors. Similarly, a “value score” for each company is computed as the average of the standardized values of the three value factors. At the end of this step each company has a growth score and a value score.

Establishing Style Baskets. Companies within the S&P 500^® Index are then ranked based on their growth and value scores. A company with a high growth score would have a higher “growth rank”, while a company with a low value score would have a lower “value rank.” For example, the S&P 500^® Index constituent with the highest value score would have a value rank of 1, while the constituent with the lowest value score would have a value rank of 500.

The companies within the S&P 500^® Index are then sorted in ascending order by the ratio their growth rank to their value rank. The companies at the top of the list have a higher growth rank (or higher growth score) and a lower value rank (or lower value score) and, therefore, exhibit pure growth characteristics. The companies at the top of the list, comprising 33% of the total index market capitalization, are included in the “growth basket.”

The companies at the bottom of the list have a higher value rank (or higher value score) and a lower growth rank (or lower growth score) and, therefore, exhibit pure value characteristics. The companies at the bottom of the list, comprising 33% of the total index market capitalization, are included in the “value basket.”

The companies in the middle of the list have similar growth ranks and value ranks and, therefore, exhibit neither pure growth nor pure value characteristics. The companies in the middle of the list, comprising 34% of the total index market capitalization, are included in the “blended basket.”

Growth and Value Indices. The style baskets described above are the starting points for the Style Indices’ construction. 100% of the float market capitalization of a company in the value basket is assigned to the underlying, and 100% of the float market capitalization of a company in the growth basket is assigned to the Growth Index.

The middle 34% of float market capitalization consists of companies that have similar growth and value ranks. The market capitalization of these companies that are in the blended basket is distributed between the underlying and the Growth Index based on their distances from the midpoint of the growth basket and the midpoint of the value basket. The midpoint of each style basket is calculated as the average of value scores and growth scores of all companies in that style basket.

Based on back-tested results, the total market capitalization is approximately equally divided among the Growth Index and the underlying. However, there is no mathematical procedure employed to force equal market capitalization for the Growth Index and Index, since price movements of constituent stocks would result in inequality immediately following any reconstitution. Therefore, the future allocation of the market capitalization to the Style Indices may not be equal.

The underlying is calculated following S&P Dow Jones’ modified market capitalization-weighted, divisor-based index methodology. Corporate actions and index changes are implemented in the same manner as for other market capitalization-weighted indices. See “Equity Index Descriptions—The S&P U.S. Indices” in the accompanying underlying supplement for additional information.

Maintenance of the Underlying

Rebalancing. The underlying is rebalanced once a year in December. The rebalancings occur after the close on the third Friday of December. The reference date for growth and value expressions is after the close of the last trading date of the previous month.

Style scores, float market-capitalization weights and growth and value midpoint averages are reset only once a year at the December rebalancing.

Other changes to the underlying are made on an as-needed basis, following the guidelines of the S&P 500^® Index. Changes in response to corporate actions and market developments can be made at any time. Constituent changes are typically announced for the S&P 500^® Index two-to-five days before they are scheduled to be implemented.

See “Equity Index Descriptions—The S&P U.S. Indices” in the accompanying underlying supplement for the treatment of other corporate actions.

Index Governance

The Americas Thematic and Strategy Index Committee (the “Index Committee”) maintains the underlying. All members of the underlying Committee are full-time professional members of S&P Dow Jones’ staff. The underlying Committee meets regularly. At each meeting, the underlying Committee may review pending corporate actions that may affect constituents of the underlying, statistics comparing the composition of the underlying to the market, companies that are being considered as candidates for addition to the underlying and any significant market events. In addition, the underlying Committee may revise index policy covering rules for selecting companies, treatment of dividends, share counts or other matters.

MARKET LINKED NOTES WITH UPSIDE PARTICIPATION WITH AVERAGING AND PRINCIPAL RETURN AT MATURITY ARE NOT DEPOSITS OR OTHER OBLIGATIONS OF A DEPOSITORY INSTITUTION AND ARE NOT INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION, THE DEPOSIT INSURANCE FUND OR ANY OTHER GOVERNMENTAL AGENCY OF THE UNITED STATES OR ANY OTHER JURISDICTION.

Market Linked Notes with Upside Participation with Averaging and Principal Return at Maturity have complex features and are not suitable for all investors. Before deciding to make an investment, you should read and understand the applicable preliminary pricing supplement and other related offering documents provided by the applicable issuer.

Market Linked Notes with Upside Participation with Averaging and Principal Return at Maturity 

Market Linked Notes with Upside Participation with Averaging and Principal Return at Maturity (“these Market Linked Notes”) offer the potential for a positive return

at maturity based on the average performance of an underlying market measure or reference asset (the “underlying”), while providing for the repayment of principal at maturity even if the underlying declines. The potential for a positive return at maturity is based on the average of the levels of the underlying on calculation days occurring at specified intervals over the term of these Market Linked Notes, and it

is therefore different than the return that might be realized on a direct investment in the underlying held for the term of these Market Linked Notes. The underlying may include an equity, bond or commodity index or exchange-traded fund, individual commodities or foreign currencies, or a basket of these underlyings.

These Market Linked Notes are designed for investors who seek exposure to the performance of an underlying, but without the downside market risk of a direct investment in the underlying. In exchange for this protection against downside market risk, investors in these Market Linked Notes must be willing to forgo interest payments, dividends (in the case of equity underlyings), and the potentially greater return that might be realized on a direct investment in the underlying. The potential for a positive return and the repayment of principal apply at maturity only and, if the issuer defaults on its payment obligations, you could lose your entire investment.

These Market Linked Notes are unsecured debt of the issuer. You will have no ability to pursue the underlying or any assets included in the underlying for payment.

Market Linked Notes with Upside Participation with Averaging and Principal Return at Maturity | A-2

The charts in this section do not reflect forgone dividend payments.

Direct investment payoff For traditional assets, such as stocks, there is a direct relationship between the change in the level of the asset and the return on the investment. For example, suppose you bought shares of a common stock at $100 per share. If you sold the shares at $120 each, the return on the investment (excluding any dividend payments) would be $20 per share, or 20%. Similarly, if you sold the shares after the price decreased to $80 (i.e., a decline of 20%), this would result in a 20% investment loss (excluding dividends).

Market Linked Notes with Upside Participation with Averaging and Principal Return at Maturity payoff

These Market Linked Notes, if held until maturity, offer a return of principal and the potential to achieve a return, subject to the averaging calculation, linked to the underlying’s performance. While these Market Linked Notes limit against losses, they may also limit upside return potential due to the averaging calculation and may not reflect any positive return at maturity even if the level of the underlying at or near maturity is significantly greater than its starting level.

To understand how these Market Linked Notes would perform under varying market conditions, consider a hypothetical Market Linked Note with the following terms:

• Principal return: 100%. These Market Linked Notes, if held until maturity, provide for the repayment of principal regardless of the performance of the underlying, subject to the ability of the issuer to make payments when due. If the issuer defaults on its payment obligations, you could lose your entire investment.

• Averaging calculation: Annual. The averaging return calculation is based on the average of the levels of the underlying observed on a specified number of calculation days throughout the term of these Market Linked Notes. On predetermined dates (e.g., annually, quarterly, monthly, etc.), the level of the underlying is recorded and those observations are used to calculate an average ending level. That calculated average ending level is compared to the starting level of the underlying to determine the percentage change. The averaging return calculation may result in a return that is less than might have been realized on a direct investment in the underlying held for the term of these Market Linked Notes.

• Participation rate: 105%. A participation rate determines how much of the average appreciation of the underlying (if any) will be reflected in the payment at maturity on these Market Linked Notes. A participation rate of 105% means that if the underlying appreciates from its starting level to its average ending level, the investor will receive a total return at maturity equal to 105% of that appreciation. For example, if the underlying appreciates by 10% based on the averaging calculation, the investor will receive a total return at maturity of 10.5% (which is 105% of 10%).

Averaging calculation methodology

The examples below are hypothetical and are provided for informational purposes only. They are not intended to represent any specific return, yield, or investment, nor are they indicative of future results. The examples illustrate the averaging calculation methodology and payoff at maturity of the Market Linked Notes described above.

Example 1: 

Term:	5 years
Calculation Days:	Annual
Principal Amount:	$1,000
Participation Rate:	105%
Starting Level:	1,000
Average Ending Level:	1,310 (refer to chart)

Averaging Percentage Return Calculation 

(Average Ending Level – Starting Level) / Starting Level (1,310 – 1,000) / 1,000 = 31%

Averaging Percentage Return Calculation
Annual Calculation Day 1	1,114
Annual Calculation Day 2	1,229
Annual Calculation Day 3	1,330
Annual Calculation Day 4	1,527
Annual Calculation Day 5	1,350
(1,114 + 1,229 + 1,330 + 1,527 + 1,350)                              5                         = 1,310

Market Linked Note Return Calculation

Averaging Percentage Return × Participation Rate

31% × 105% = 32.55%

Payment to Investor 

Principal Amount + (Principal Amount × Averaging Percentage Return × Participation Rate) 

$1,000 + ($1,000 × 31% × 105%) = $1,325.50 per Market Linked Note

Comparison with Direct Investment Return

In example 1, if you had purchased the underlying at its Starting Level, held it for the term of these Market Linked Notes, and then sold it at its level on the final Calculation Day, you would have realized a 35% return on your investment (leaving aside any dividends), since the level of the underlying on the final Calculation Day is 35% greater than the Starting Level. By contrast, the Averaging Percentage Return calculated for purposes of these Market Linked Notes is only 31%. Because the level of the

underlying on the final Calculation Day is greater than its Average Ending Level over all of the Calculation Days, the Averaging Percentage Return calculated for purposes of these Market Linked Notes is less than the return that could have been achieved on a direct investment in the underlying held for the term of these Market Linked Notes. In addition, if any dividends were

paid on the underlying over the term of these Market Linked Notes, the return on these Market Linked Notes would have underperformed a direct investment to an even greater extent, because the return on these Market Linked Notes will not compensate you for any dividends paid on the underlying.

A-5 | Market Linked Notes with Upside Participation with Averaging and Principal Return at Maturity

Example 2: 

Term:	5 years
Calculation Days:	Annual
Principal Amount:	$1,000
Participation Rate:	105%
Starting Level:	1,000
Average Ending Level:	987 (refer to chart)

Averaging Percentage Return Calculation 

(Average Ending Level – Starting Level) / Starting Level

(987 – 1,000) / 1,000 = –1.3%

Averaging Percentage Return Calculation
Annual Calculation Day 1	900
Annual Calculation Day 2	935
Annual Calculation Day 3	950
Annual Calculation Day 4	1,050
Annual Calculation Day 5	1,100
(900 + 935 + 950 + 1,050 + 1,100)                           5                       = 987

Market Linked Note Return Calculation

Because the Average Ending Level is less than the Starting Level, there is no positive return at maturity on these Market Linked Notes.

Payment to Investor

Since the Average Ending Level is less than the Starting Level, you will receive the Principal Amount of $1,000 per Market Linked Note.

Comparison with Direct Investment Return

In example 2, if you had purchased the underlying at its Starting Level, held it for the term of these Market Linked Notes, and then sold it at its level on the final Calculation Day, you would have realized a 10% return on your investment (leaving aside any dividends), since the level of the underlying on the final Calculation Day is 10% greater than the Starting Level. By

contrast, because the Average Ending Level of the underlying over all of the Calculation Days is less than the Starting Level, the Averaging Percentage Return calculated for purposes of these Market Linked Notes is negative. In this example, the Averaging Percentage Return is negative, and you will receive no return on your investment at maturity, even though a direct investment would have resulted in a positive return. If any dividends were paid on the underlying over the term of these Market Linked Notes, these Market Linked Notes would have underperformed a direct investment to an even greater extent, because the return on these Market Linked Notes will not compensate you for any dividends paid on the underlying.

All payments on these Market Linked Notes are subject to the ability of the issuer to make such payments to you when they are due, and you will have no ability to pursue the underlying or any asset included in the underlying for payment. If the issuer defaults on its payment obligations, you could lose your entire investment.

Estimated value of Market Linked Notes with Upside Participation with Averaging and Principal Return at Maturity

The original offering price of these Market Linked Notes will include certain costs that are borne by you. Because of these costs, the estimated value of these Market Linked Notes on the pricing date will be less than the original offering price. If specified

in the applicable pricing supplement, these costs may include the underwriting discount or commission, the hedging profits of the issuer’s hedging counterparty (which may be an affiliate of the issuer), hedging and other costs associated with the offering, and costs relating to the issuer’s funding considerations for debt of this type. See “General risks and investment considerations” herein and the applicable pricing supplement for more information.

The issuer will disclose the estimated value of these Market Linked Notes in the applicable pricing supplement. The estimated value of these Market Linked Notes will be determined by estimating the value of the combination of hypothetical financial instruments that would replicate the payout on these Market Linked Notes, which combination consists of a non-interest bearing, fixed-income bond, and one or more derivative instruments underlying the economic terms of these Market Linked Notes. You should read the applicable pricing supplement for more information about the estimated value of these Market Linked Notes and how it is determined.

Which investments are right for you?

It is important to read and understand the applicable preliminary pricing supplement and other related offering documents and consider several factors before making an investment decision.

An investment in these Market Linked Notes may help you modify your portfolio’s risk-return profile to more closely reflect your market views. However, because of the averaging calculation, you may sacrifice some return opportunities and will forgo interest payments and dividend payments (in the case of equity underlyings).

These Market Linked Notes are not suitable for all investors, but may be suitable for investors aiming to:

• Fully protect against market losses at maturity

• Gain or increase exposure to different asset classes

• Participate in a portion of any appreciation of the underlying from its starting level to its average ending level

You can find a discussion of risks and investment considerations on the next page and in the preliminary pricing supplement and other related offering documents for these Market Linked Notes. The following questions, which you should review with your financial advisor, are intended to initiate a conversation about whether these Market Linked Notes are right for you.

• What is your time horizon? Do you foresee liquidity needs? Will you be able to hold these investments until maturity?

• Does full protection against market declines take precedence for you over full participation in potential appreciation of the underlying, dividend payments, or fixed returns?

• What is your outlook on the market? How confident are you in your portfolio’s ability to weather a market decline?

• What is your sensitivity to the tax treatment for your investments?

• Are you dependent on your investments for current income?

• Are you willing to accept the credit risk of the applicable issuer in order to obtain the exposure to the underlying that these Market Linked Notes provide?

Before making an investment decision, please work with your financial advisor to determine which investment products may be appropriate given your financial situation, investment goals, and risk profile.

General risks and investment considerations

These Market Linked Notes have complex features and are not suitable for all investors. They involve a variety of risks and may be linked to a variety of different underlyings. Each of these Market Linked Notes and each underlying will have its own unique set of risks and investment considerations. Before you invest in these Market Linked Notes, you should thoroughly review the relevant preliminary pricing supplement and other related offering documents for a comprehensive discussion of the risks associated with the investment. The following are general risks and investment considerations applicable to these Market Linked Notes:

• Performance risk and opportunity costs. Because these Market Linked Notes do not offer a minimum return, the yield that you will receive on these Market Linked Notes may be less than the return you could earn on other investments, including a traditional interest-bearing debt security with the same maturity date of the applicable issuer or another issuer with a similar credit rating, and could be zero.

• Underperformance risk. The return you receive at maturity of these Market Linked Notes may be less than the return you might have realized on a direct investment in the underlying held for the term of these Market Linked Notes. This will be the case if the underlying appreciates and its level at or near maturity is greater than it was, on average, on the specified calculation days during the term of these Market Linked Notes. For example, if the underlying generally appreciates over the term of these Market Linked Notes, the level of the underlying at or near maturity will be greater than it was, on average, on the calculation days, and your return on these Market Linked Notes will be less than the return you might have realized on a direct investment in the underlying held for the term of these Market Linked Notes. Furthermore, because of the averaging calculation, it is possible that these Market Linked Notes will not reflect any positive return at maturity even if the level of the underlying at or near maturity is significantly greater than its starting level.

• Liquidity risk. These Market Linked Notes are not appropriate for investors who may have liquidity needs prior to maturity. These Market Linked Notes are not listed on any securities exchange and are generally illiquid instruments. Neither Wells Fargo Securities nor any other person is required to maintain a secondary market for these Market Linked Notes. Accordingly, you may be unable to sell your Market Linked Notes prior to their maturity date. If you choose to sell these Market Linked Notes prior to maturity, assuming a buyer is available, you may receive less in sale proceeds than the original offering price.

• Market value uncertain. These Market Linked Notes are not appropriate for investors who need their investments to maintain a stable value during their term. The value of your Market Linked Notes prior to maturity will be affected by numerous factors, such as performance, volatility and dividend rate, if applicable, of the underlying; interest rates; the time remaining to maturity; the correlation among basket components, if applicable; and the applicable issuer’s creditworthiness.

• Costs to investors. The original offering price of these Market Linked Notes will include certain costs that are borne by you. These costs will adversely affect the economic terms of these Market Linked Notes and will cause their estimated value on the pricing date to be less than the original offering price. If specified in the applicable pricing supplement, these costs may include the underwriting discount or commission, the hedging profits of the issuer’s hedging counterparty (which may be an affiliate of the issuer), hedging and other costs associated with the offering, and costs relating to the issuer’s funding considerations for debt of this type. These costs will adversely affect any secondary market price for these Market Linked Notes, which may be further reduced by a bid-offer spread. As a result, unless market conditions and other relevant factors change significantly in your favor following the pricing date, any secondary market price for these Market Linked Notes is likely to be less than the original offering price.

• Credit risk. Any investment in these Market Linked Notes is subject to the ability of the applicable issuer to make payments to you when they are due, and you will have no ability to pursue the underlying or any assets included in the underlying for payment. If the issuer defaults on its payment obligations, you could lose your entire investment. In addition, the actual or perceived creditworthiness of the issuer may affect the value of these Market Linked Notes prior to maturity.

• No periodic interest or dividend payments. These Market Linked Notes do not typically provide periodic interest. These Market Linked Notes linked to equities do not provide for a pass through of any dividend paid on the underlying equities.

• Estimated value considerations. The estimated value of these Market Linked Notes that is disclosed in the applicable pricing supplement will be determined by the issuer or an underwriter of the offering, which underwriter may be an affiliate of the issuer and may be Wells Fargo Securities. The estimated value will be based on the issuer’s or the underwriter’s proprietary pricing models and assumptions and certain inputs that may be determined by the issuer or underwriter in its discretion. Because other dealers may have different views on these inputs, the estimated value that is disclosed in the applicable pricing supplement may be higher, and perhaps materially higher, than the estimated value that will be determined by other dealers in the market.

• Conflicts of interest. Potential conflicts of interest may exist between you and the applicable issuer and/or Wells Fargo Securities. For example, the applicable issuer, Wells Fargo Securities, or one of their respective affiliates may engage in business with companies whose securities are included in the underlying, or may publish research on such companies or the underlying. In addition, the applicable issuer, Wells Fargo Securities, or one of their respective affiliates may be the calculation agent for the purposes of making important determinations that affect the payments on these Market Linked Notes. Finally, the estimated value of these Market Linked Notes may be determined by the issuer or an underwriter of the offering, which underwriter may be an affiliate of the issuer and may be Wells Fargo Securities.

• Effects of trading and other transactions. Trading and other transactions by the applicable issuer, Wells Fargo Securities, or one of their respective affiliates could affect the underlying or the value of these Market Linked Notes.

• Basket risk. If the underlying is a basket, the basket components may offset each other. Any appreciation of one or more basket components may be moderated, wholly offset, or more than offset, by depreciation of one or more other basket components.

• ETF risk. If the underlying is an exchange-traded fund (ETF), it may underperform the index it is designed to track as a result of costs and fees of the ETF and differences between the constituents of the index and the actual assets held by the ETF. In addition, an investment in these Market Linked Notes linked to an ETF involves risks related to the index underlying the ETF, as discussed in the next risk consideration.

• Index risk. If the underlying is an index, or an ETF that tracks an index, your return on these Market Linked Notes may be adversely affected by changes that the index publisher may make to the manner in which the index is constituted or calculated. Furthermore, if the index represents foreign securities markets, you should understand that foreign securities markets tend to be less liquid and

more volatile than U.S. markets, and that there is generally less information available about foreign companies than about companies that file reports with the U.S. Securities and Exchange Commission. Moreover, if the index represents emerging foreign securities markets, these Market Linked Notes will be subject to the heightened political and economic risks associated with emerging markets. If the index includes foreign securities and the level of the index is based on the U.S. dollar value of those foreign securities, these Market Linked Notes will be subject to currency exchange rate risk in addition to the other risks described above, as the level of the index will be adversely affected if the currencies in which the foreign securities trade depreciate against the U.S. dollar.

• Commodity risk. These Market Linked Notes linked to commodities will be subject to a number of significant risks associated with commodities. Commodity prices tend to be volatile and may fluctuate in ways that are unpredictable and adverse to you. Commodity markets are frequently subject to disruptions, distortions, and changes due to various factors, including the lack of liquidity in the markets, the participation of speculators, and government regulation and intervention. Moreover, commodity indices may be adversely affected by a phenomenon known as “negative roll yield,” which occurs when future prices of the commodity futures contracts underlying the index are higher than current prices. Negative roll yield can have a significant negative effect on the performance of a commodity index. Furthermore, for commodities that are traded in U.S. dollars but for which market prices are driven by global demand, any strengthening of the U.S. dollar against relevant other currencies may adversely affect the demand for, and therefore the price of, those commodities.

• Currency risk. These Market Linked Notes linked to currencies will be subject to a number of significant risks associated with currencies. Currency exchange rates are frequently subject to intervention by governments, which can be difficult to predict and can have a significant impact on exchange rates. Moreover, currency exchange rates are driven by complex factors relating to the economies of the relevant countries that can be difficult to understand and predict. Currencies issued by emerging market governments may be particularly volatile and will be subject to heightened risks.

• Bond risk. These Market Linked Notes linked to bond indices or exchange-traded funds will be subject to a number of significant risks associated with bonds. In general, if market interest rates rise, the value of bonds will decline. In addition, if the market perception of the creditworthiness of the relevant bond issuers falls, the value of bonds will generally decline.

• Tax considerations. You should review carefully the relevant preliminary pricing supplement and other related offering documents and consult your tax advisors regarding the application of the U.S. Federal income tax laws to your particular circumstances, as well as any tax consequences arising under the laws of any state, local, or non-U.S. jurisdiction.
