Market-Linked Notes Based on a Basket of Three Underliers Due May 27, 2021

n The notes offered by this pricing supplement are unsecured senior 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 a basket (the “basket”) consisting of the following three basket components (with the weightings indicated parenthetically): shares of the iShares^® Core U.S. Aggregate Bond ETF (50%), the S&P 500^® Index (25%) and the EURO STOXX 50^® Index (25%).

n If the basket appreciates from its initial basket level to its final basket level, you will receive a positive return at maturity equal to 100% of that appreciation. However, if the basket depreciates, you will be repaid your principal at maturity but will not receive any return on your investment. Even if the basket appreciates from the initial basket level to the final basket level, so that you do receive a positive return at maturity, there is no assurance that your total return at maturity on the notes will compensate you for the effects of inflation or be as great as the yield you could have achieved on a conventional debt security of ours of comparable maturity. In exchange for repayment of principal at maturity if the basket depreciates, investors in the notes must be willing to forgo any dividends paid on the stocks included in the S&P 500^® Index or the EURO STOXX 50^® Index and any distributions of interest payments on the bonds held by the iShares^® Core U.S. Aggregate Bond ETF over the term of the notes.

n In order to obtain the modified exposure to the basket that the notes provide, investors must be willing to accept (i) an investment that may have limited or no liquidity and (ii) the risk of not receiving any amount due under the notes if we and Citigroup Inc. default on our obligations. All payments on the notes are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.

Additional Information

General. 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, prospectus supplement and prospectus contain important disclosures that are not repeated in this pricing supplement. For example, certain events may occur that could affect your payment at maturity. These events, including market disruption events and other events affecting the basket components, and their consequences are described in the accompanying product supplement in the sections “Description of the Notes—Certain Additional Terms for Notes Linked to ETF Shares or Company Shares—Consequences of a Market Disruption Event; Postponement of a Valuation Date,” “—Dilution and Reorganization Adjustments” and “—Delisting, Liquidation or Termination of an Underlying ETF” with respect to the basket component that is an ETF and in the sections “Description of the Notes—Certain Additional Terms for Notes Linked to an Underlying Index—Consequences of a Market Disruption Event; Postponement of a Valuation Date” and “—Discontinuance or Material Modification of an Underlying Index” with respect to the basket components that are indices. The accompanying underlying supplement contains important disclosures regarding the basket components that are 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 connection with your investment in the notes. Certain terms used but not defined in this pricing supplement are defined in the accompanying product supplement.

Postponement of the valuation date. If the valuation date is postponed for a reason that affects less than all of the basket components, the final basket level will be calculated based on (i) for each unaffected basket component, its closing level or closing price, as applicable, on the originally scheduled valuation date and (ii) for each affected basket component, its closing level or closing price, as applicable, on the valuation date as postponed (or, if earlier, the first scheduled trading day for that basket component following the originally scheduled valuation date on which a market disruption event did not occur with respect to that basket component). See “Description of the Notes—Certain Additional Terms for Notes Linked to ETF Shares or Company Shares—Consequences of a Market Disruption Event; Postponement of a Valuation Date” and “Description of the Notes—Certain Additional Terms for Notes Linked to an Underlying Index—Consequences of a Market Disruption Event; Postponement of a Valuation Date” in the accompanying product supplement.

Dilution and reorganization adjustments. The initial component value with respect to shares of the iShares^® Core U.S. Aggregate Bond ETF is a “Relevant Price” for purposes of the section “Description of the Notes—Certain Additional Terms for Notes Linked to ETF Shares or Company Shares—Dilution and Reorganization Adjustments” in the accompanying product supplement. Accordingly, the initial component value with respect to shares of the iShares^® Core U.S. Aggregate Bond ETF is subject to adjustment upon the occurrence of any of the events described in that section.

Hypothetical Examples

The diagram below illustrates your payment at maturity for a range of hypothetical percentage changes from the initial basket level to the final basket level.

Investors in the notes will not receive any dividends paid on the stocks included in the S&P 500^® Index or the EURO STOXX 50^® Index or any distributions of interest payments on the bonds held by the iShares^® Core U.S. Aggregate Bond ETF. The examples below do not show any effect of lost dividend or distribution yield over the term of the notes. See “Summary Risk Factors—Investing in the notes is not equivalent to investing in the basket components” below.

Market-Linked Notes Payment at Maturity Diagram

Your actual payment at maturity per note will depend on the actual final basket level. The examples below are intended to illustrate how your payment at maturity will depend on whether the final basket level is greater than or less than the initial basket level and by how much.

Example 1—Upside Scenario. The hypothetical final basket level is 110.00 (a 10.00% increase from the initial basket level), which is greater than the initial basket level.

Basket Component	Initial Component Value	Hypothetical Final Component Value	Hypothetical Component Return
Shares of the iShares® Core U.S. Aggregate Bond ETF	$110.46	$115.98	5%
S&P 500® Index	2,076.06	2,387.47	15%
EURO STOXX 50® Index	3,010.12	3,461.64	15%
Hypothetical Final Basket Level:	100.00 × [1 + (5% × 50%) + (15% × 25%) + (15% × 25%)] = 110.00

Payment at maturity per note	= $1,000 + the note return amount
	= $1,000 + ($1,000 × basket return percentage × upside participation rate)
	= $1,000 + ($1,000 × 10% × 100%)
	= $1,000 + $100
	= $1,100

Market-Linked Notes Based on a Basket of Three Underliers Due May 27, 2021

In this scenario, because the basket appreciated by 10.00% from the initial basket level to the hypothetical final basket level, you would receive a total return at maturity of 10.00%, which is 100% of the appreciation of the basket.

Example 2—Par Scenario. The hypothetical final basket level is 95.00 (a 5.00% decrease from the initial basket level), which is less than the initial basket level.

Basket Component	Initial Component Value	Hypothetical Final Component Value	Hypothetical Component Return
Shares of the iShares® Core U.S. Aggregate Bond ETF	$110.46	$88.37	-20%
S&P 500® Index	2,076.06	2,387.47	15%
EURO STOXX 50® Index	3,010.12	3,160.63	5%
Hypothetical Final Basket Level:	100.00 × [1 + (-20% × 50%) + (15% × 25%) + (5% × 25%)] = 95.00

Payment at maturity per note	= $1,000 + the note return amount
	= $1,000 + $0
	= $1,000

In this scenario, because the basket depreciated from the initial basket level to the hypothetical final basket level, you would be repaid the stated principal amount of your notes at maturity but would not receive any positive return on your investment. In this scenario, even though the S&P 500^® Index and the EURO STOXX 50^® Index appreciated, that appreciation is more than offset by the depreciation of the shares of the iShares^® Core U.S. Aggregate Bond ETF.

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 basket components. 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 advisers 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.

n You may not receive any return on your investment in the notes. You will receive a positive return on your investment in the notes only if the basket appreciates from the initial basket level to the final basket level. If the final basket level is equal to or less than the initial basket level, you will receive only the stated principal amount of $1,000 for each note you hold at maturity. As the notes do not pay any interest, even if the basket appreciates from the initial basket level to the final basket level, 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 of comparable maturity.

n 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.

n The notes are designed for investors who seek exposure to the basket components but who are willing to forgo any dividends or distributions on the basket components in exchange for the repayment of principal at maturity if the basket depreciates. You should understand that, for purposes of measuring the performance of the basket components, the levels and prices used will not reflect the receipt or reinvestment of dividends or distributions on the basket components or their underlying securities. Dividend or distribution yield on the basket components would be expected to represent a significant portion of the overall return on a direct investment in the basket components, but will not be reflected in the performance of the basket components as measured for purposes of the notes (except to the extent that dividends and distributions reduce the levels or prices of the basket components). The magnitude of this lost dividend or distribution yield may be particularly significant in the case of the iShares Core U.S. Aggregate Bond ETF. The iShares Core U.S. Aggregate Bond ETF is a bond fund and, as with any bond fund, distributions of interest payments on the bonds held by the fund would be expected to make up a significant portion of the overall yield on a direct investment in the fund. The notes will not reflect distributions of interest payments on the bonds held by iShares Core U.S. Aggregate Bond ETF and, therefore, will not reflect the interest component of the yield on the iShares Core U.S. Aggregate Bond ETF. As a result, the performance of the iShares Core U.S. Aggregate Bond ETF as measured for purposes of the notes may be significantly less than the return that a direct investor in the iShares Core U.S. Aggregate Bond ETF would realize.

Citigroup Global Markets Holdings Inc.

Market-Linked Notes Based on a Basket of Three Underliers Due May 27, 2021

For this reason, your return on the notes may be significantly less than the return that could be achieved on a direct investment in the basket components. This is an important trade-off that investors in the notes must be willing to make in exchange for the repayment of principal at maturity even if the basket declines.

n 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 basket declines or does not appreciate sufficiently from the initial basket level to the final basket level. 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 5-year 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.

n Investing in the notes is not equivalent to investing in the basket components. You will not have voting rights, rights to receive dividends on stocks or distributions of interest on bonds or any other rights with respect to the basket components or the securities included in the basket components. The payment scenarios described in this pricing supplement do not show any effect of lost dividend or distribution yield over the term of the notes.

n Your payment at maturity depends on the closing levels or closing prices, as applicable, of the basket components on a single day. Because your payment at maturity depends solely on the closing levels or closing prices, as applicable, of the basket components on the valuation date, you are subject to the risk that the closing levels or closing prices on that day may be lower, and possibly significantly lower, than on one or more other dates during the term of the notes. If you had invested directly in the basket components, or if the payment at maturity were based on an average of the closing levels or closing prices, as applicable, of the basket components throughout the term of the notes, you might have achieved better returns.

n 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.

n 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. CGMI currently intends to make a secondary market in relation to the notes and to provide an indicative bid price for the notes on a daily basis. Any indicative bid price for the notes provided by CGMI will be determined in CGMI’s sole discretion, taking into account prevailing market conditions and other relevant factors, and will not be a representation by CGMI that the notes can be sold at that price, or at all. CGMI may suspend or terminate making a market and providing indicative bid prices without notice, at any time and for any reason. If CGMI suspends or terminates making a market, there may be no secondary market at all for the notes because it is likely that CGMI 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.

n 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.

n 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 issue price. The difference is attributable to certain costs associated with selling, structuring and hedging the notes that are included in the issue price. These costs include (i) the selling concessions 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 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 our secondary market rate” below.

n 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 of the basket components, the correlation among the basket components, dividend or distribution yields on the basket components or the securities included in the basket components 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.

n The estimated value of the notes would be lower if it were calculated based on our secondary market rate. 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. Our internal funding rate is generally lower than our secondary

May 2016 PS-5

Citigroup Global Markets Holdings Inc.

Market-Linked Notes Based on a Basket of Three Underliers Due May 27, 2021

market rate, which is the rate that CGMI 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 our secondary market rate, 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 we will pay to investors in the notes, which do not bear interest.

Because there is not an active market for traded instruments referencing our outstanding debt obligations, CGMI determines our secondary market rate 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 CGMI makes in its sole discretion. As a result, our secondary market rate is not a market-determined measure of our creditworthiness, but rather reflects the market’s perception of our parent company’s creditworthiness as adjusted for discretionary factors such as CGMI’s preferences with respect to purchasing the notes prior to maturity.

n The estimated value of the notes is not an indication of the price, if any, at which CGMI or any other 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, any value of the notes determined for purposes of a secondary market transaction will be based on our secondary market rate, which will likely result in a lower value for the notes than if our internal funding rate were used. In addition, 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 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 issue price.

n 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 levels or prices of the basket components and a number of other factors, including the volatility of the basket components, the correlation among the basket components, the dividend and distribution yields on the basket components or the securities included in the basket components, the volatility of the exchange rate between the U.S. dollar and the euro, the correlation between that exchange rate and the level of the EURO STOXX 50^® Index, interest rates generally, the time remaining to maturity and our and/or Citigroup Inc.’s creditworthiness, as reflected in our secondary market rate. Changes in the levels or prices of the basket components 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 issue price.

n Immediately following issuance, any secondary market bid price provided by CGMI, and the value that will be indicated on any brokerage account statements prepared by CGMI 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.

n The basket components may offset each other. The performance of one basket component may not correlate with the performance of the other basket components. If one of the basket components appreciates, the other basket components may not appreciate as much or may even depreciate. In such event, the appreciation of one of the basket components may be moderated, wholly offset or more than offset by lesser appreciation or by depreciation in the value of one or more of the other basket components.

n The basket components may be highly correlated in decline. The performances of the basket components may become highly correlated during periods of declining prices. This may occur because of events that have broad effects on markets generally or on the markets that the basket components track. If the basket components become correlated in decline, the depreciation of one basket component will not be offset by the performance of the other basket components and, in fact, each basket component may contribute to an overall decline from the initial basket level to the final basket level.

n The EURO STOXX 50^® Index is subject to risks associated with the Eurozone. The companies whose stocks constitute the EURO STOXX 50^® Index are leading companies in the Eurozone. A number of countries in the Eurozone are undergoing a financial crisis affecting their economies, their ability to meet their sovereign financial obligations and their financial institutions. Countries in the Eurozone that are not currently experiencing a financial crisis may do so in the future as a result of developments in other Eurozone countries. The economic ramifications of this financial crisis, and its effects on the companies that make up the EURO STOXX 50^® Index, are impossible to predict. This uncertainty may contribute to significant volatility in the EURO STOXX 50^® Index, and adverse developments affecting the Eurozone may affect the EURO STOXX 50^® Index in a way that adversely affects the value of and return on the notes. Furthermore, you should understand that there is generally less publicly available information about non-U.S. companies than about U.S. companies that are subject to the reporting requirements of the SEC, and non-U.S. companies are generally subject to accounting, auditing and financial reporting standards and requirements and securities trading rules that are different from those applicable to U.S. reporting companies.

n The performance of the EURO STOXX 50^® Index will not be adjusted for changes in the exchange rate between the euro and the U.S. dollar. The EURO STOXX 50^® Index is composed of stocks traded in euro, the value of which may be subject to a high degree of fluctuation relative to the U.S. dollar. However, the performance of the EURO STOXX 50^® Index and the value of your notes will not be adjusted for exchange rate fluctuations. If the euro appreciates relative to the U.S. dollar over the term of the notes, your return on the notes will underperform an alternative investment that offers exposure to that appreciation in addition to the change in the level of the EURO STOXX 50^® Index.

n The iShares^® Core U.S. Aggregate Bond ETF is subject to significant risks, including interest rate-related and credit-related risks. Because the performance of the notes is linked to the shares of the iShares^® Core U.S. Aggregate Bond ETF, the notes are exposed to fluctuations in the value of U.S. dollar-denominated fixed-income securities. The performance of the iShares^® Core U.S. Aggregate Bond ETF that is measured for purposes of the notes will only reflect changes in the market prices of the fixed-income securities held by the iShares^® Core U.S. Aggregate Bond ETF and will not reflect interest payments on these fixed-income securities. As a result, the performance of the iShares^® Core U.S. Aggregate Bond ETF that is measured for purposes of the notes will be less, and perhaps significantly less, than the return that would be realized by a direct investor in the iShares^® Core U.S. Aggregate Bond ETF. The market prices of the fixed-income securities held by the iShares^® Core U.S. Aggregate Bond ETF are volatile and significantly influenced by a number of factors, particularly the yields on these fixed-income securities as compared to current market interest rates and the actual or perceived credit quality of the issuers of these fixed-income securities.

In general, the value of fixed-income securities is significantly affected by changes in current market interest rates. As interest rates rise, the prices of fixed-income securities, including those held by the iShares^® Core U.S. Aggregate Bond ETF, are likely to decrease. Securities with longer durations tend to be more sensitive to interest rate changes, usually making them more volatile than securities with shorter durations. The eligibility criteria for the fixed-income securities included in the index that underlies the iShares^® Core U.S. Aggregate Bond ETF, which mandates that each security must have a minimum term remaining to maturity of one year for continued eligibility, means that, at any time, only longer-term securities underlie the iShares^® Core U.S. Aggregate Bond ETF, which thereby increases the risk of price volatility in the underlying securities and, consequently, the volatility in the value of the iShares^® Core U.S. Aggregate Bond ETF. As a result, rising interest rates may cause the value of the bonds held by the iShares^® Core U.S. Aggregate Bond ETF and the value of the basket to decline, possibly significantly.

Interest rates are subject to volatility due to a variety of factors, including:

· sentiment regarding underlying strength in the U.S. economy and global economies;

· expectations regarding the level of price inflation;

· sentiment regarding credit quality in the U.S. and global credit markets;

· central bank policies regarding interest rates; and

· the performance of U.S. and foreign capital markets.

In addition, the prices of the fixed-income securities held by the iShares^® Core U.S. Aggregate Bond ETF are significantly influenced by the creditworthiness of the issuers of those fixed-income securities. The fixed-income securities underlying the iShares^® Core U.S. Aggregate Bond ETF may have their credit ratings downgraded, including a downgrade from investment grade to non-investment grade status, or credit spreads may widen significantly. Following a ratings downgrade or the widening of credit spreads, some or all of the fixed-income securities may suffer significant and rapid price declines. These events may affect only a few or a large number of the fixed-income securities. For example, during the most recent credit crisis in the United States, credit spreads widened significantly as the market demanded very high yields on corporate bonds and, as a result, the prices of the bonds underlying the iShares^® Core U.S. Aggregate Bond ETF dropped significantly. There can be no assurance that some or all of the factors that contributed to this credit crisis will not return during the term of the notes, and, consequently, depress the price, perhaps significantly, of the underlying bonds and therefore the value of the iShares^® Core U.S. Aggregate Bond ETF, the basket and the notes.

The holdings of the iShares^® Core U.S. Aggregate Bond ETF include U.S. Treasury bonds. Recently, U.S. Treasury bonds have been trading near their historic high trading price. If the price of U.S. Treasury bonds reverts to its historic mean or otherwise falls, as a result of a general increase in interest rates or perceptions of reduced credit quality of the U.S. government or otherwise, the value of the U.S. Treasury bonds held by the iShares^® Core U.S. Aggregate Bond ETF will decline, which could have a negative impact on the performance of the basket and the return on your notes.

The iShares^® Core U.S. Aggregate Bond ETF may invest in mortgage-backed securities, some of which may not be backed by the full faith and credit of the U.S. government. Mortgage-backed securities are subject to prepayment risk and extension risk. Because of these risks, mortgage-backed securities react differently to change in interest rates than other bonds. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain mortgage-backed securities.

n Even if the iShares^® Core U.S. Aggregate Bond ETF pays a distribution that it identifies as special or extraordinary, no adjustment will be required under the notes for that distribution unless it meets the criteria specified in the accompanying product supplement. In general, an adjustment will not be made under the terms of the notes for any cash distribution paid on shares of the iShares^® Core U.S. Aggregate Bond ETF unless the amount of the distribution per share, together with any other distributions paid in the same quarter, exceeds the distribution paid per share in the most recent quarter by an amount equal to at least 10% of the closing price of the shares of the iShares^® Core U.S. Aggregate Bond ETF on the date of declaration of the distribution. Any distribution will reduce the closing price of the shares of the iShares^® Core U.S. Aggregate Bond ETF by the amount of the distribution per share. If the iShares^® Core U.S. Aggregate Bond ETF pays any distribution for which an adjustment is not made under the terms of the notes, holders of the notes will be adversely affected. See “Description of the Notes—Certain Additional Terms for Notes Linked to ETF Shares or Company Shares—Dilution and Reorganization Adjustments—Certain Extraordinary Cash Dividends” in the accompanying product supplement.

Market-Linked Notes Based on a Basket of Three Underliers Due May 27, 2021

n An adjustment will not be made for all events that may have a dilutive effect on or otherwise adversely affect the market price of the iShares^® Core U.S. Aggregate Bond ETF. For example, we will not make any adjustment for ordinary distributions or extraordinary distributions that do not meet the criteria described above. Moreover, the adjustments we do make may not fully offset the dilutive or adverse effect of the particular event. Investors in the notes may be adversely affected by such an event in a circumstance in which a direct holder of the shares of the iShares^® Core U.S. Aggregate Bond ETF would not.

n The notes may become linked to shares of an issuer other than the iShares^® Core U.S. Aggregate Bond ETF upon the occurrence of a reorganization event or upon the delisting of the shares of the iShares^® Core U.S. Aggregate Bond ETF. For example, if the iShares^® Core U.S. Aggregate Bond ETF enters into a merger agreement that provides for holders of the shares of the iShares^® Core U.S. Aggregate Bond ETF to receive shares of another entity, the shares of such other entity will become the applicable basket component for all purposes of the notes upon consummation of the merger. Additionally, if the shares of the iShares^® Core U.S. Aggregate Bond ETF are delisted, or the iShares^® Core U.S. Aggregate Bond ETF is otherwise terminated, the calculation agent may, in its sole discretion, select shares of another ETF to be the applicable basket component. See “Description of the Notes—Certain Additional Terms for Notes Linked to ETF Shares or Company Shares—Dilution and Reorganization Adjustments” and “—Delisting, Liquidation or Termination of an Underlying ETF” in the accompanying product supplement.

n The price of the shares of the iShares^® Core U.S. Aggregate Bond ETF may not completely track the performance of the index it seeks to track or the net asset value per share of the iShares^® Core U.S. Aggregate Bond ETF. The price of the shares of the iShares^® Core U.S. Aggregate Bond ETF will reflect transaction costs and fees that are not included in the calculation of the Barclays U.S. Aggregate Bond Index, the index that it seeks to track. In addition, the iShares^® Core U.S. Aggregate Bond ETF may not hold all of the securities included in, and may hold securities and derivative instruments that are not included in, the Barclays U.S. Aggregate Bond Index. All of these factors may lead to a lack of correlation between the performance of the iShares^® Core U.S. Aggregate Bond ETF and the Barclays U.S. Aggregate Bond Index. In addition, corporate actions with respect to the equity securities constituting the Barclays U.S. Aggregate Bond Index or held by the iShares^® Core U.S. Aggregate Bond ETF (such as mergers and spin-offs) may impact the variance between the performances of the iShares^® Core U.S. Aggregate Bond ETF and the Barclays U.S. Aggregate Bond Index. Finally, because the shares of the iShares^® Core U.S. Aggregate Bond ETF are traded on NYSE Arca, Inc. and are subject to market supply and investor demand, the market value of one share of the iShares^® Core U.S. Aggregate Bond ETF may differ from the net asset value per share of the iShares^® Core U.S. Aggregate Bond ETF.

During periods of market volatility, securities underlying the iShares^® Core U.S. Aggregate Bond ETF may be unavailable in the secondary market, market participants may be unable to calculate accurately the net asset value per share of the iShares^® Core U.S. Aggregate Bond ETF and the liquidity of the iShares^® Core U.S. Aggregate Bond ETF may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares in the iShares^® Core U.S. Aggregate Bond ETF. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares of the iShares^® Core U.S. Aggregate Bond ETF. As a result, under these circumstances, the market value of shares of the iShares^® Core U.S. Aggregate Bond ETF may vary substantially from the net asset value per share of the iShares^® Core U.S. Aggregate Bond ETF. For all of the foregoing reasons, the performance of the iShares^® Core U.S. Aggregate Bond ETF may not correlate with the performance of the Barclays U.S. Aggregate Bond Index as well as the net asset value per share of the iShares^® Core U.S. Aggregate Bond ETF, which could materially and adversely affect the value of the securities in the secondary market and/or reduce your payment at maturity.

n Changes made by the investment adviser to or the sponsor of a basket component may affect the basket component. We are not affiliated with the investment adviser to theiShares^® Core U.S. Aggregate Bond ETF or with the sponsors of the S&P 500^® Index, the EURO STOXX 50^® Index or the Barclays U.S. Aggregate Bond Index. Changes that affect the basket components may affect the value of your notes. The sponsor of an index may add, delete or substitute the securities that constitute the index or make other methodological changes that could affect the level of the index. In addition, the investment adviser to the iShares^® Core U.S. Aggregate Bond ETF may change the manner in which the iShares^® Core U.S. Aggregate Bond ETF operates or its investment objectives at any time. We are not affiliated with any such index sponsor or investment adviser and, accordingly, we have no control over any changes any such index sponsor or investment adviser may make. Such changes could be made at any time and could adversely affect the performance of the basket components and the value of and your payment at maturity on the notes.

n Our offering of the notes does not constitute a recommendation of the basket or the basket components. The fact that we are offering the notes does not mean that we believe that investing in an instrument linked to the basket or any of the basket components is likely to achieve favorable returns. In fact, as we are part of a global financial institution, our affiliates may have positions (including short positions) in the securities included in the basket components or in instruments related to the basket components or such securities, and may publish research or express opinions, that in each case are inconsistent with an investment linked to the basket components. These and other activities of our affiliates may affect the values of the basket components in a way that has a negative impact on your interests as a holder of the notes.

n The value of a basket component may be adversely affected by our or our affiliates’ hedging and other trading activities. We have hedged our obligations under the notes through CGMI or other of our affiliates, who have taken positions directly in the applicable basket components or the securities included in the basket components and other financial instruments related to the basket components or such securities and may adjust such positions during the term of the notes. Our affiliates also trade the applicable basket components or the securities included in the basket components and other financial instruments related to the

basket components or such securities 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 values of the basket components in a way that negatively affects the value of the notes. They could also result in substantial returns for us or our affiliates while the value of the notes declines.

n We and our affiliates may have economic interests that are adverse to yours as a result of our affiliates’ business activities. Our affiliates may currently or from time to time engage in business with the issuers of the securities included in the basket components, including extending loans to, making equity investments in or providing advisory services to such issuers. In the course of this business, we or our affiliates may acquire non-public information about such issuers, which we will not disclose to you. Moreover, if any of our affiliates is or becomes a creditor of any such issuer, they may exercise any remedies against such issuer that are available to them without regard to your interests.

n The calculation agent, which is an affiliate of ours, will make important determinations with respect to the notes. If certain events occur, such as market disruption events, the discontinuance of the S&P 500^® Index or the EURO STOXX 50^® Index or events with respect to the iShares^® Core U.S. Aggregate Bond ETF that may require a dilution adjustment or the delisting of the iShares^® Core U.S. Aggregate Bond ETF, CGMI, as calculation agent, will be required to make discretionary judgments that could significantly affect your payment at maturity. 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.

Hypothetical Historical Information About the Basket

Because the basket exists solely for purposes of the notes, historical information on the performance of the basket does not exist for dates prior to the pricing date. The graph below sets forth the hypothetical historical daily closing levels of the basket for the period from January 3, 2011 to May 24, 2016, assuming that the basket was created on January 3, 2011 with the same basket components and corresponding weights and with a level of 100 on that date. The hypothetical performance of the basket is based on the actual closing levels and closing prices, as applicable, of the basket components on the applicable dates. We obtained these closing levels and closing prices from Bloomberg L.P., without independent verification. Any historical trend in the level of the basket during the period shown below is not an indication of the performance of the basket during the term of the notes.

Information About the Basket Components

iShares^® Core U.S. Aggregate Bond ETF

The iShares^® Core U.S. Aggregate Bond ETF is an exchange-traded fund that seeks to track the investment results of the Barclays U.S. Aggregate Bond Index (the “ETF underlying index”), which measures the performance of the total U.S. investment-grade bond market. For purposes of the notes, the performance of the iShares^® Core U.S. Aggregate Bond ETF will reflect only its price performance, as any distributions paid on the shares of the iShares^® Core U.S. Aggregate Bond ETF will not be factored into a determination of the closing price of the iShares^® Core U.S. Aggregate Bond ETF (except to the extent that distributions paid will reduce the closing price of the iShares^® Core U.S. Aggregate Bond ETF). The Barclays U.S. Aggregate Bond Index is a broad-based benchmark that measures the performance of the U.S. investment-grade bond market.

The iShares^® Core U.S. Aggregate Bond ETF generally seeks to track the performance of the ETF underlying index by investing approximately 90% of its assets in the bonds represented in the ETF underlying index and in securities that provide substantially similar exposure to securities in the ETF underlying index. The remainder of assets is invested in comparable bonds or in cash and high-quality, liquid short-term instruments, including shares of money market funds affiliated with BlackRock Fund Advisors. The iShares^® Core U.S. Aggregate Bond ETF concentrates 25% or more of its total assets in a particular industry or industries to approximately the same extent that the ETF underlying index is concentrated.

The iShares^® Core U.S. Aggregate Bond ETF is an investment portfolio managed by iShares^® Inc. BlackRock Fund Advisors is the investment adviser to the iShares^® Core U.S. Aggregate Bond ETF. iShares^®, Inc. is a registered investment company that consists of numerous separate investment portfolios, including the iShares^® Core U.S. Aggregate Bond ETF.

Description of the Barclays U.S. Aggregate Bond Index

We obtained all information contained in this pricing supplement regarding the Barclays U.S. Aggregate Bond Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, Barclays Capital Inc. (“Barclays”), the sponsor of the Barclays U.S. Aggregate Bond Index. Barclays has no obligation to continue to publish, and may discontinue publication of, the Barclays U.S. Aggregate Bond Index at any time. Neither Citigroup Inc. nor CGMI has independently verified the accuracy or completeness of any information with respect to the Barclays U.S. Aggregate Bond Index in connection with the offer and sale of the notes.

The Barclays U.S. Aggregate Bond Index is a broad-based benchmark that measures the performance of the U.S. investment grade bond market, which includes investment-grade U.S. Treasury securities, investment-grade U.S. agency securities, investment-grade corporate bonds, mortgage pass-through securities, commercial mortgage-backed securities and asset-backed securities that are publicly offered for sale in the United States.

Rules for Inclusion

In order to be eligible for inclusion in the Barclays U.S. Aggregate Bond Index, U.S. Treasuries, government-related and corporate securities must have $250 million or more of outstanding face value. U.S. Treasuries held in the Federal Reserve SOMA account (both purchases at issuance and net secondary market transactions) are deducted from the total amount outstanding. Any new issuance bought at auction by the Federal Reserve does not enter the Barclays U.S. Aggregate Bond Index. Net secondary market purchases and sales are adjusted at each month-end with a one-month lag. Mortgage-backed securities (“MBSs”) must be pool aggregates with $1 billion or more outstanding, asset-backed securities (“ABSs”) must have a deal size of $500 million or more and a tranche size of

May 2016 PS-12

Citigroup Global Markets Holdings Inc.

Market-Linked Notes Based on a Basket of Three Underliers Due May 27, 2021

$25 million or more and commercial mortgage-backed securities (“CMBSs”) must have a deal size of $500 million or more, with at least $300 million outstanding remaining in the deal and a tranche size of $25 million or more.

The securities included in the Barclays U.S. Aggregate Bond Index must be rated investment-grade (Baa3/BBB-/BBB-) or higher using the middle rating of Moody’s, S&P and Fitch after dropping the highest and lowest available ratings. When a rating from only two agencies is available, the lower is used. When a rating from only one agency is available, that is used to determine index eligibility. Expected ratings at issuance may be used when there are other index-eligible bonds from the same issuer that hold the same actual rating as the expected rating.

Securities included in the Barclays U.S. Aggregate Bond Index must have a remaining maturity of at least one year, regardless of optionality. Securities with a coupon that converts from fixed to floating rate must have at least one year until the conversion date. MBSs must have a weighted average maturity of at least one year and CMBSs and ABSs must have a remaining average life of at least one year. Fixed-to-floating perpetual securities are included in the Barclays U.S. Aggregate Bond Index. These are included until one year before their first call date, provided that they meet all other index criteria.

Senior and subordinated issues are included in the Barclays U.S. Aggregate Bond Index. Capital securities (hybrid capital) are eligible during their fixed-rate term and exit the index one year prior to their conversion to floating-coupon securities.

Only fully taxable issues are eligible for inclusion in the Barclays U.S. Aggregate Bond Index, including taxable municipal securities. Build America Bonds with the tax credit issued to the issuer are eligible for inclusion; those with tax credits issued to investors are considered tax exempt. Dividend-received deduction-eligible and qualified dividend income-eligible securities are excluded from the Barclays U.S. Aggregate Bond Index.

A security’s principal and coupons must be denominated in U.S. dollars to be eligible for inclusion. Coupons must be fixed-rate, step-up coupons or coupons that change according to a predetermined schedule. Capital securities with coupons that convert from fixed to floating rate are index eligible, given that they are currently fixed rate. The maturity date for such securities will be considered the conversion date. Fixed-to-floating rate perpetual capital securities that do not have coupon rate step-ups on their first call date will remain index eligible for their fixed-rate term, provided that they meet all other inclusion rules and exit the index one year prior to their conversion to floating-coupon securities. Hybrid adjustable rate mortgages are eligible for inclusion in the Barclays U.S. Aggregate Bond Index during their fixed term, but exit the index one year prior to their conversion to an adjustable rate.

SEC-registered securities, bonds exempt from registration at the time of issuance, and Rule 144A securities with registration rights are index eligible. A security with both Regulation S and Rule 144A tranches is treated as one security in par value. To prevent double-counting, the 144A tranche is used to represent the issue and comprises the combined amount outstanding of the 144A and Regulation S tranches. Issues with a global market of issue are also eligible for inclusion, as are bonds from issuers that have de-registered, provided that the bonds were previously SEC-registered or Rule 144A securities with registration rights.

Original issue zero coupon bonds, underwritten medium-term notes, enhanced equipment trust certificates, certificates of deposit and, as of January 1, 2011, covered bonds, are also eligible for inclusion in the Barclays U.S. Aggregate Bond Index. Bonds with equity-type features (e.g., warrants, convertible debt and contingent capital securities), Treasury STRIPs, inflation-linked bonds, non-ERISA eligible CMBS issues, fixed-rate perpetual securities, structured notes, loan participation notes, pass-through certificates, illiquid securities with no available internal or third-party price source and, as of January 1, 2011, CMBS A1A tranches, are not eligible for inclusion in the index.

Rebalancing

The compositions of the “returns universe” is rebalanced at each month-end and represents the fixed set of bonds on which index returns are calculated for the ensuing month. The “statistics universe” is a forward-looking version that changes daily to reflect issues dropping out and entering the index, but is not used for return calculation. On the last business day of the month (the “rebalancing date”), the composition of the latest statistics universe becomes the returns universe for the following month.

During the month, indicative changes to securities (e.g., credit rating changes, sector reclassification, amount outstanding changes, corporate actions, ticker changes) are reflected in both the statistics universe and returns universe of the index on a daily basis. These changes may cause bonds to enter or fall out of the statistics universe of the index on a daily basis, but will affect the composition of the returns universe only at month-end, when the index is rebalanced.

Intra-month cash flows from interest and principal payments contribute to monthly index returns, but are not reinvested at any short-term reinvestment rate in between rebalance dates to earn an incremental return. However, after the rebalancing, cash is effectively reinvested into the returns universe for the following month, so that index results over two or more months reflect monthly compounding.

Qualifying securities issued but not necessarily settled on or before the month-end rebalancing date qualify for inclusion in the following month’s index if required security reference information and pricing are readily available.

Index Calculation

All bonds eligible for inclusion in the Barclays U.S. Aggregate Bond Index are priced on a daily basis at 3 p.m. New York time, predominantly by Barclays market makers. The pricing source varies by the type of security.

May 2016 PS-13

Citigroup Global Markets Holdings Inc.

Market-Linked Notes Based on a Basket of Three Underliers Due May 27, 2021

Bonds can be quoted in a variety of ways, including nominal spreads over benchmark securities or Treasuries, spreads over swap curves, or direct price quotes as a percentage of par. In most instances, the quote type used is a spread measure that results in daily security price changes from the movement of the underlying curve (swap or Treasury) and/or changes in the quoted spread.

The initial price for new corporate issues entering the index is the offer side. However, after that, all bonds in the index are priced on the bid side. The primary price for each security is analyzed and compared with other third-party pricing sources through statistical routines and scrutiny by research staff. Significant discrepancies are researched and corrected, as necessary.

United States Federal Tax Considerations

In the opinion of our tax 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. If you are a U.S. Holder, 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.

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 2.542%, compounded semi-annually, and that the projected payment schedule with respect to a note consists of a single payment of $1,134.649 at maturity. The following table states the amount of interest (without taking into account any adjustment to reflect the difference, if any, between the actual and the projected amount of the contingent payment on a note) that will be deemed to have accrued with respect to a note for each accrual period (assuming a day count convention of 30 days per month and 360 days per year), based upon the comparable yield set forth above:

ACCRUAL PERIOD	OID DEEMED TO ACCRUE DURING ACCRUAL PERIOD (PER NOTE)	TOTAL OID DEEMED TO HAVE ACCRUED FROM ISSUE DATE (PER NOTE) AS OF END OF ACCRUAL PERIOD
Issue date through June 30, 2016	$2.330	$2.330
July 1, 2016 through December 31, 2016	$12.740	$15.070
January 1, 2017 through June 30, 2017	$12.902	$27.971
July 1, 2017 through December 31, 2017	$13.066	$41.037
January 1, 2018 through June 30, 2018	$13.232	$54.268
July 1, 2018 through December 31, 2018	$13.400	$67.668
January 1, 2019 through June 30, 2019	$13.570	$81.238
July 1, 2019 through December 31, 2019	$13.743	$94.981
January 1, 2020 through June 30, 2020	$13.917	$108.898
July 1, 2020 through December 31, 2020	$14.094	$122.992
January 1, 2021 through maturity date	$11.656	$134.649

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.

Subject to the discussions under “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.

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

The actual underwriting fee will be equal to $25.00 for each $1,000 note sold by CGMI directly to the public and will otherwise be equal to the selling concession provided to selected dealers, as described in this paragraph. CGMI will pay selected dealers not affiliated with CGMI a fixed selling concession of $25.00 for each note they sell to accounts other than fee-based advisory accounts. CGMI will pay selected dealers not affiliated with CGMI, which may include dealers acting as custodians, a variable selling concession of up to $5.00 for each $1,000 note they sell to fee-based advisory accounts. Broker-dealers affiliated with CGMI, including Citi International Financial Services, Citigroup Global Markets Singapore Pte. Ltd. and Citigroup Global Markets Asia Limited, will receive a fixed selling concession, and financial advisers employed by such affiliated broker-dealers will receive a fixed selling concession, of $25.00 for each $1,000 note they sell. CGMI will pay the registered representatives of CGMI a fixed selling concession of $25.00 for each $1,000 note they sell directly to the public.

CGMI is an affiliate of ours. Accordingly, this offering will conform with the requirements addressing conflicts of interest when distributing the securities of an affiliate set forth in Rule 5121 of the Financial Industry Regulatory Authority. Client accounts over which Citigroup Inc. or its subsidiaries have investment discretion will not be permitted to purchase the notes, either directly or indirectly, without the prior written consent of the client.

A portion of the net proceeds from the sale of the notes will be used to hedge our obligations under the notes. We have hedged our obligations under the notes through CGMI or other of our affiliates. CGMI or such other of our affiliates may profit from this hedging activity even if the value of the notes declines. This hedging activity could affect the closing levels or prices of the basket components and, therefore, the value of and your return on the notes. For additional information on the ways in which our counterparties may hedge our obligations under the notes, see “Use of Proceeds and Hedging” in the accompanying prospectus.

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.

For a period of approximately four months following issuance of the notes, the price, if any, at which CGMI 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 CGMI or its affiliates (which value CGMI may also publish through one or more financial information vendors), 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 hedging profit expected to be realized by CGMI or its affiliates over the term of the notes. The amount of this temporary upward adjustment will decline to zero on a straight-line basis over the four-month temporary adjustment period. However, CGMI 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.”
