Summary Description of the Index

The Citi Radar^SM 3.5 Excess Return Index (the “Index”) is published by Citigroup Global Markets Limited (the “Index Administrator”), which is an affiliate of ours.  The Index tracks the hypothetical performance of a rules-based investment methodology premised on the idea that there is a relationship between the prevailing interest rate environment in the United States and the relative performance of different sectors of the U.S. equity and Treasury markets. Based on that premise, the Index seeks to determine on a daily basis whether the United States is in a “Rising” interest rate environment or a “Not Rising” interest rate environment. If the Index determines that there is a “Rising” interest rate environment, the Index will allocate exposure to exchange-traded funds (“ETFs”) representing sectors of the U.S. equity market that, according to the Index’s investment thesis, may outperform the broader market in a rising interest rate environment. If, on the other hand, the Index determines that there is a “Not Rising” interest rate environment, the Index will allocate exposure to different ETFs representing sectors of the U.S. equity market that, according to the Index’s investment thesis, may outperform the broader market in a falling or flat interest rate environment. In an attempt to maintain a volatility target of 3.5%, the Index will also allocate exposure to U.S. Treasury note futures and, potentially, to uninvested cash. Collectively, these allocations – to the selected equity sector ETFs, U.S. Treasury note futures and uninvested cash – make up a hypothetical investment portfolio. The performance of the Index will reflect the performance of that hypothetical investment portfolio, as adjusted daily in response to the observed interest rate environment and pursuant to the volatility targeting feature described below, and subject to the excess return deduction and index fee described below.

The Index determines whether the prevailing interest rate environment is “Rising” or “Not Rising” on each day by observing the average rate of 3-month U.S. dollar LIBOR for each month in the immediately preceding four months (the “Rates Signal”). If the average rate of 3-month U.S. dollar LIBOR increased from each month to the next in that four-month period, then the Index will determine that there is a “Rising” interest rate environment. In all other circumstances, the Index will determine that there is a “Not Rising” interest rate environment.

There is uncertainty about the future of 3-month U.S. dollar LIBOR. If the Index Administrator determines that 3-month U.S. dollar LIBOR has been discontinued or is no longer widely relied upon by market participants as a benchmark interest rate, the Index Administrator may select a successor rate to be substituted for 3-month U.S. dollar LIBOR in the calculation of the Rates Signal. In that event, the successor rate chosen by the Index Administrator may differ in important ways from 3-month U.S. dollar LIBOR, and Index performance based on the successor rate may be less favorable than it would have been had the Rates Signal continued to be based on 3-month U.S. dollar LIBOR.

The following table lists the equity sector ETFs and U.S. Treasury note futures index to which the Index will allocate exposure in each observed interest rate environment. The table also indicates that the Index may allocate exposure to uninvested cash.

We refer to the hypothetical investment portfolio tracked by the Index at any given time as the “Selected Portfolio” at that time. The selected equity sector ETFs together make up a hypothetical “Equity Allocation” in the Selected Portfolio and will be equally weighted with each other. The applicable U.S. Treasury note futures index makes up a hypothetical “Treasury Futures Allocation.” We refer to the overall allocation to the Equity Allocation and the

Treasury Futures Allocation together as the “Invested Allocation” within the Selected Portfolio. In addition to these allocations, the Selected Portfolio may have a hypothetical allocation to uninvested cash, which we refer to as the “Cash Allocation”. No interest or other return will accrue on the Cash Allocation.

The Index determines how much exposure to allocate to each of the Equity Allocation, the Treasury Futures Allocation and the Cash Allocation on a daily basis in a manner designed to maintain a target volatility of the Index of 3.5%. This volatility-targeting feature is applied in two stages. First, the Index will allocate exposure between the Equity Allocation and the Treasury Futures Allocation within the Invested Allocation based on the volatility of the current Equity Allocation over the prior six months, with higher volatility resulting in a lower Equity Allocation, and vice versa. Second, the Index will allocate exposure between the Invested Allocation and the Cash Allocation based on the volatility of the Invested Allocation over the prior one month. In this second stage, the Index will, if necessary, reduce exposure to the Invested Allocation and increase exposure to the Cash Allocation (which has no volatility) in an attempt to maintain a rolling one-month Selected Portfolio volatility of 3.5%.

The chart below illustrates the composition of four hypothetical Selected Portfolios, assuming various combinations of the Rates Signal, the trailing six-month volatility of the current Equity Allocation and the trailing one-month volatility of the Invested Allocation. The chart is intended solely for the purpose of illustrating how various allocations together make up a Selected Portfolio, depending on the Rates Signal, the trailing six-month volatility of the current Equity Allocation and the trailing one-month volatility of the Invested Allocation. It is not an indication of what the composition of the Selected Portfolio may be at any given point in time. The chart refers to each equity sector ETF by its ticker symbol, which can be found in the table above.

Each U.S. Treasury note futures index tracks the performance of a hypothetical investment, rolled quarterly, in a near-maturity U.S. Treasury note futures contract. A U.S. Treasury note futures contract is a contract for the purchase of U.S. Treasury notes with maturities falling within a specified range on a fixed date in the future. Accordingly, the value of a U.S. Treasury note futures contract will fluctuate with changes in the market value of the underlying U.S. Treasury notes. In general, the value of a U.S. Treasury note will fall as market interest rates rise, and rise as market interest rates fall. However, the value of a U.S. Treasury note futures contract will also fluctuate based on factors that are unique to a futures contract, such as supply and demand in the futures market, the time remaining to the maturity of the futures contract and market interest rates over the term of the contract. These factors are likely to cause a position in a U.S. Treasury note futures contract to reflect an implicit financing cost, which will lower the return on the futures contract as compared to a direct investment in the underlying U.S. Treasury notes. Accordingly, we expect the performance of each U.S. Treasury note futures index to generally

reflect changes in the value of the underlying U.S. Treasury notes, as reduced by an implicit financing cost. We expect the implicit financing cost to rise if market interest rates rise.

In determining the performance of the Index, a rate equal to the federal funds effective rate will be deducted from the daily performance of each equity sector ETF. We refer to this deduction, together with the implicit financing cost reflected in each U.S. Treasury note futures index, as the “excess return deduction”. The excess return deduction is likely to cause the performance of the Selected Portfolio as measured for purposes of the Index to be significantly less than the actual performance of the equity sector ETFs and the U.S. Treasury notes underlying the U.S. Treasury futures that make up the Selected Portfolio. The impact of the excess return deduction will increase if market interest rates rise. The performance of the Index will also be reduced on a daily basis by an index fee of 0.75% per annum.

This section contains only a summary description of the Index and does not describe all of its important features in detail. Before investing in the notes, you should carefully review the more detailed description of the Index contained in the section “Description of the Citi Radar^SM 3.5 Excess Return Index” in this index supplement.

The Index is subject to important risks, including the following:

For more information about the important risks affecting the Index, you should carefully read the section “Summary Risk Factors—Key Risks Relating to the Index” in this pricing supplement and “Key Risks Relating to the Index” in this index supplement.

The Selected Portfolio is a hypothetical investment portfolio. There is no actual portfolio of assets to which any investor is entitled or in which any investor has any ownership or other interest. The Index is merely a mathematical calculation that is performed by reference to hypothetical positions in the Equity Allocation, Treasury Futures Allocation and Cash Allocation and the other Index rules.

Summary Payment Terms

The particular payment terms of the notes will be set forth in the applicable pricing supplement and will be linked to the performance of the Index. The notes provide for the repayment of the stated principal amount at maturity, regardless of the performance of the Index. The notes may pay coupon payments at a rate that varies based on the performance of the Index, or the notes may not pay interest and may instead provide for a single payment at maturity based on the performance of the Index. The specific terms of the notes will be specified in the applicable pricing supplement.

Any potential payment on the notes that depends on the performance of the Index may be positive, or it may be zero, depending on the specific terms of the notes. You should carefully read the applicable pricing supplement to understand the payment terms of the notes and the circumstances in which you may not receive any return on your investment in the notes. The specific terms of the notes will be determined on the date we price the notes for initial sale to the public, which we refer to as the “Pricing Date.”

Any potential payment on the notes that depends on the performance of the Index will be based on the Closing Level of the Index on one or more dates specified in the applicable pricing supplement (each, a “Valuation Date”), subject to the specific terms set forth in the applicable pricing supplement.

In addition to the risks associated with the performance of the Index, all payments due on the notes are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., as guarantor of the obligations of Citigroup Global Markets Holdings Inc. If Citigroup Global Markets Holdings Inc. and Citigroup Inc. default on their obligations under the notes, you may not receive any payment owed to you, including the repayment of the stated principal amount of your notes at maturity.

Before deciding whether to invest in the notes, you should carefully read and understand the sections “Risk Factors Relating to the Notes” and “Description of the Citi Radar^SM 3.5 Excess Return Index” in this index supplement as well as the particular terms and risk factors described in the applicable pricing supplement.

Certain events may happen that could affect any payment owed to you under the notes, such as the occurrence of market disruption events or other events affecting the Index. Those events are described in this index supplement under “Description of the Notes” and “Description of the Citi Radar^SM 3.5 Excess Return Index” and will not be repeated in the applicable pricing supplement. As a result, you should carefully review and understand the section “Description of the Notes” and “Description of the Citi Radar^SM 3.5 Excess Return Index” in this index supplement.

Risk Factors Relating to the Notes

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, including the risk that we may default on our obligations under the notes, and are also subject to risks associated with the Index because your return on the notes will depend on the performance of the Index.

Risk Factors Relating to All Notes

You May Not Receive Any Return On Your Investment in the Notes, in Which Case You Will Suffer a Loss On Your Investment in Real Value Terms. Your return on the notes, if any, will depend on the performance of the Index. If the Index does not perform favorably (which will depend on the specific terms of the notes set forth in the applicable pricing supplement), you may not receive any return on your investment in the notes. Although the notes provide for the repayment of the stated principal amount at maturity regardless of the performance of the Index, you may nevertheless suffer a loss on your investment in the notes, in real value terms, if you do not receive a positive return on the notes. 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 return. The potential loss in real value terms will be greater the longer the term of the notes.

Even if you do receive a positive return on your investment in the notes, there can be 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 return you could have achieved on a conventional debt security of Citigroup Global Markets Holdings Inc. (guaranteed by Citigroup Inc.) of comparable maturity. 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 conventional debt securities, is appropriate for you.

The Notes Will Not Pay Any Coupon Unless Otherwise Specified in the Applicable Pricing Supplement. Unless the applicable pricing supplement specifies that the notes will pay a coupon, the notes will not pay any interest or provide for any other payments prior to maturity. Accordingly, unless the applicable pricing supplement specifically provides for a coupon payment, you should not invest in the notes if you seek current income during the term of the notes.

If the Notes Provide For a Coupon That Depends on the Performance of the Index, the Coupon Payment May Be Zero on One or More Coupon Payment Dates. If the applicable pricing supplement provides for a coupon payment but the amount of such payment varies depending on the performance of the Index or otherwise, you should understand that you may not receive any payment on one or more (or any) coupon payment dates during the term of the notes. You should not invest in notes with such terms if you seek certainty of receiving current income during the term of the notes.

If a Maximum Return Applies to the Notes, Your Return on the Notes Will Be Limited. If applicable, the maximum return will be a percentage of the stated principal amount of the notes that will be determined on the Pricing Date and set forth in the applicable pricing supplement. Your total return at maturity on notes with a maximum return will be limited to the specified maximum return (excluding any coupon payments, if applicable), even if the return of the Index is significantly greater. You should not invest in notes that have a maximum return if you seek to participate in the full appreciation of the Index.

The Notes are Subject to the Credit Risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., the Guarantor of any Payments Due on the Notes. You are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc. The notes are not guaranteed by any entity other than Citigroup Inc. Any actual or anticipated changes to Citigroup Global Markets Holdings Inc.’s or Citigroup Inc.’s credit ratings or credit spreads may adversely affect the value of the notes. If Citigroup Global Markets Holdings Inc. defaults on its obligations and Citigroup Inc. defaults on its guarantee obligations under the notes, your investment will be at risk and you could lose some or all of your investment. As a result, the value of the notes prior to maturity will be affected by changes in the market’s view of Citigroup Global Markets Holdings Inc.’s and Citigroup Inc.’s creditworthiness.

Any decline, or anticipated decline, in either of their credit ratings or increase, or anticipated increase, in the credit spreads charged by the market for taking either of their credit risk is likely to adversely affect the value of the notes.

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 Notes Will Not Be Listed on a Securities Exchange and You May Not Be Able To Sell Your Notes Prior To Maturity. Unless otherwise specified in the applicable pricing supplement, the notes will not be listed on a securities exchange. Accordingly, the notes may have limited or no liquidity, and you should not invest in the notes unless you are willing to hold them to maturity.

Citigroup Global Markets Inc. (“CGMI”) or, if applicable, any other entity named as underwriter or agent in the applicable pricing supplement may, but is not obligated to, make a market in the notes. If CGMI or such other underwriter or agent does make a market in the notes, it may discontinue doing so at any time. Because we do not expect that other broker-dealers will participate significantly in any secondary market for the notes, the price at which you may be able to sell your notes prior to maturity is likely to depend on the price, if any, at which CGMI or such other underwriter or agent is willing to transact. If at any time CGMI or such other underwriter or agent were not to make a market in the notes, it is likely that there would be no secondary market at all for the notes. The price, if any, at which CGMI, such other underwriter or agent or any other buyer may be willing to purchase your notes in any secondary market that may develop may be significantly less than the stated principal amount; therefore, any sale of the notes prior to maturity may result in a substantial loss. As a result, you should be prepared to hold your notes to maturity.

The Value Of Your Notes Prior To Maturity Will Fluctuate Based On Many Unpredictable Factors. The value of your notes prior to maturity will fluctuate based on the level of the Index and a number of other factors, including those described below. Some of these factors are interrelated in complex ways. As a result, the effect of any one factor may be offset or magnified by the effect of one or more other factors. The paragraphs below describe what we expect to be the impact on the value of the notes of a change in a specific factor, assuming all other conditions remain constant. You should understand that the value of your notes at any time prior to maturity may be significantly less than the stated principal amount.

The level of the Index will be influenced by the value and volatility of its Constituents, as well as by complex and interrelated political, economic, financial and other factors that affect the capital markets generally. Hedging by us or our counterparties (which may include our affiliates), the issuance of other securities similar to the notes and other trading activities by our affiliates may also affect the level, which could negatively affect the value of the notes.

It is important for you to understand that the impact of one of the factors discussed above may offset, or magnify, some or all of any change in the value of the notes attributable to one or more of the other factors.

Our Affiliates May Have Published Research, Expressed Opinions or Provided Recommendations that are Inconsistent With Investing in the Notes and May Do So in the Future, and any such Research, Opinions or Recommendations Could Adversely Affect the Level of the Index. CGMI and other of our affiliates may publish research from time to time relating to the financial markets, any of the Constituents of the Index or the hypothetical investment methodology of the Index. Any research, opinions or recommendations provided by CGMI may influence the price or level of any Constituent of the Index, and they may be inconsistent with purchasing or holding the notes. CGMI and other of our affiliates may have published or may publish research or other opinions that call into question the investment view implicit in an investment in the notes. Any research, opinions or recommendations expressed by such affiliates of ours may not be consistent with each other and may be modified from time to time without notice. Investors should make their own independent investigation of the Constituents of the Index, the Index itself and the merits of investing in the notes.

The Price or Level of a Constituent or of the Index May Be Affected by Our or Our Affiliates’ Hedging and Other Trading Activities. In anticipation of the sale of the notes, we expect to hedge our obligations under the notes directly or through one of our affiliates, which may involve taking positions directly in the Constituents of the Index or other instruments that may affect the values of the Constituents of the Index. We or our counterparties may also adjust this hedge during the term of the notes and close out or unwind this hedge on or before any Valuation Date, which may involve, among other things, us or our counterparties purchasing or selling such Constituents or other instruments. This hedging activity on or prior to the Pricing Date could potentially affect the values of the Constituents of the Index on the Pricing Date and, accordingly, potentially increase the Initial Index Level, which may adversely affect your return on the notes. Additionally, this hedging activity during the term of the notes, including on or near any Valuation Date, could negatively affect the level of the Index and, therefore, adversely affect your payment at maturity on the notes. This hedging activity may present a conflict of interest between your interests as a holder of the notes and the interests we and/or our counterparties, which may be our affiliates, have in executing, maintaining and adjusting hedging transactions. These hedging activities could also affect the price, if any, at which CGMI or, if applicable, any other entity may be willing to purchase your notes in a secondary market transaction.

We and our affiliates may also trade the Constituents of the Index and/or other instruments that may affect the values of the Constituents of the Index on a regular basis (taking long or short positions or both), for our or their accounts, for other accounts under management or to facilitate transactions, including block transactions, on behalf of customers. As with our or our affiliates’ hedging activity, this trading activity could affect the prices or levels of the Constituents of the Index on any Valuation Date and, therefore, adversely affect the performance of the Index and the notes.

It is possible that these hedging or trading activities could result in substantial returns for us or our affiliates while the value of the notes declines.

We and Our Affiliates May Have Economic Interests That Are Adverse to Those of the Holders of the Notes as a Result of Our or Our Affiliates’ Business Activities. We or our affiliates may currently or from time to time engage in business with the issuers of the stocks that are held by the equity sector ETFs, 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. We do not make any representation or warranty to any purchaser of the notes with respect to any matters whatsoever relating to our or our affiliates’ business with any such issuer. Moreover, if we or any of our affiliates are or become a creditor of any such issuer or otherwise enter into any transaction with any such issuer in the regular course of business, we or such affiliate may exercise any remedies against such issuer that are available to them without regard to the impact on your interests as a holder of the notes.

We are the Notes Calculation Agent and, In That Capacity, May Make Important Determinations With Respect to the Notes. As Notes Calculation Agent, we will determine, among other things, the amount owed to you at maturity of the notes. In addition, if certain events occur, we will be required to make certain discretionary judgments that could significantly affect the amount you receive at maturity. In making these judgments, our interests could be adverse to your interests as a holder of the notes. Such judgments could include, among other things:

Any of these determinations made by us, in our capacity as Notes Calculation Agent, may adversely affect any payment owed to you under the notes.

Discontinuance of the Index Could Adversely Affect the Value of the Notes. The Index Administrator is not required to publish the Index throughout the term of the notes. The Index Administrator may determine to discontinue the Index, among other reasons, as a result of the occurrence of a material Regulatory Event. See “Description of the Citi Radar^SM 3.5 Excess Return Index” in this Index Supplement for more information. If the Index is discontinued, the Notes Calculation Agent will have the sole discretion to substitute a successor index that is comparable to the discontinued Index and is not precluded from considering other indices that are calculated and published by the Notes Calculation Agent or any of its affiliates. Any such successor index may not perform favorably.

If the Notes Calculation Agent does not select a successor index, then the Notes Calculation Agent will calculate a substitute Closing Level for the Index for all dates from and after the time of discontinuance. The substitute Closing Level will be determined by the Notes Calculation Agent in accordance with the formula for calculating the Index last in effect prior to such discontinuance, except that, at all times after such discontinuance, (i) the Equity Allocation will consist of a basket of all six equity sector ETFs eligible for inclusion in the Index, equally weighted at the time of discontinuance of the Index but without further rebalancing thereafter and (ii) the Treasury Futures Allocation will consist of the Citi Interest Rate 2Y U.S. Treasury Futures Market Tracker Index. In such an event, the Closing Level of the Index so determined will cease to reflect the Index’s portfolio selection methodology. For purposes of clarity, if the Index Administrator discontinues publication of the Index and the notes calculation agent is required to calculate a substitute Closing Level for the Index, the Notes Calculation Agent will make that calculation applying all of the current features of the Index, including the volatility targeting, the excess return deduction and the index fee, with the exception that the components of the Equity Allocation and Treasury Futures Allocation will become fixed as described above. The substitute closing level of the Index may perform unfavorably after the discontinuance. In such an event, even though the Index will no longer apply its portfolio selection methodology, the index fee will continue to be deducted.

Certain U.S. Federal Tax Consequences of an Investment in the Notes are Uncertain. The notes may be assumed by Citigroup Inc., as provided in the accompanying prospectus. The law regarding whether or not such an assumption would be considered a “significant modification” of the notes is not entirely clear and, if the Internal

Revenue Service (the “IRS”) were to treat the assumption as a significant modification, a U.S. holder would generally be required to recognize gain (if any) on the notes and the timing and character of income recognized with respect to the notes, as well as the withholding tax consequences to a non-U.S. holder of the notes, after the assumption could be affected significantly. You should read carefully the discussion under “United States Federal Tax Considerations” in this index supplement. You should also consult your tax adviser regarding the U.S. federal tax consequences of an assumption of the notes.

Risk Factors Relating to the Index

The following discussion of risks relating to the Index should be read together with the section “Description of the Citi Radar^SM 3.5 Excess Return Index” below, which defines and further describes a number of the terms and concepts referred to in this section.

The Index May Not Be Successful And May Underperform Alternative Investment Strategies. There can be no assurance that the Index will achieve positive returns over any period. The Index tracks the hypothetical performance of a rules-based investment methodology that selects a hypothetical investment portfolio (the Selected Portfolio) to track on a daily basis based on a measure of the prevailing interest rate environment in the United States (the Rates Signal). The performance of the Index over any period will depend on the performance of the Selected Portfolio over that time period, as adjusted daily in response to the observed interest rate environment and pursuant to a volatility targeting feature, and subject to the excess return deduction and index fee, all as more fully described in the section “Description of the Citi Radar^SM 3.5 Excess Return Index” in this index supplement. In general, if the equity sector ETFs and the U.S. Treasury notes underlying the U.S. Treasury note futures that make up the Selected Portfolio appreciate over a period by more than the excess return deduction and index fee, the level of the Index will increase, and if they depreciate over that period or appreciate by less than the excess return deduction and index fee, the level of the Index will decrease. The performance of the Index may be less favorable than alternative investment strategies that could have been implemented, including an investment in a passive index fund.

There Is Uncertainty About The Future Of 3-Month U.S. Dollar LIBOR, And If 3-Month U.S. Dollar LIBOR Is Discontinued Or Is No Longer Widely Relied Upon By Market Participants As A Benchmark Interest Rate, The Index May Be Adversely Affected. On March 5, 2021, the U.K. Financial Conduct Authority (the “FCA”), which regulates LIBOR, announced that 3-month U.S. dollar LIBOR will either cease to be provided by any administrator or no longer be representative after June 30, 2023. It is impossible to predict whether and to what extent banks will continue to provide LIBOR submissions to the administrator of LIBOR, whether LIBOR rates will cease to be published or supported before or after June 30, 2023 or whether any additional reforms to LIBOR may be enacted in the United Kingdom or elsewhere. At this time, no consensus exists as to what rate or rates may become accepted alternatives to LIBOR.

If 3-month U.S. dollar LIBOR is discontinued or is permanently no longer published or is no longer widely relied upon by market participants as a benchmark interest rate (other than for legacy financial instruments linked to 3-month U.S. dollar LIBOR), the Index Administrator may select a substitute or successor rate that it has determined (after consulting any source that it deems reasonable) is (1) the industry-accepted substitute or successor rate or (2) if there is no such industry-accepted substitute or successor rate, a substitute or successor rate which is the most comparable to 3-month U.S. dollar LIBOR (as 3-month U.S. dollar LIBOR exists as of the launch date of the Index). Upon selection of a substitute or successor rate, the Index Administrator may determine (after consulting any source that it deems reasonable) any adjustment factor it determines is needed to make such substitute or successor rate comparable to 3-month U.S. dollar LIBOR, in a manner which is consistent with any industry-standard practice for such substitute or successor rate. In this circumstance, the successor rate chosen by the Index Administrator may differ in important ways from 3-month U.S. dollar LIBOR, and the Rates Signal determined on the basis of the successor rate may be less effective at identifying the prevailing interest rate environment in the United States. As a result, Index performance based on a successor rate may be less favorable than it would have been had the Rates Signal continued to be based on 3-month U.S. dollar LIBOR.

The Index’s Investment Thesis May Be Wrong. The Index methodology is premised on the idea that there is a relationship between the prevailing interest rate environment in the United States and the relative performance of different sectors of the U.S. equity market. Specifically, the Index methodology seeks to implement the thesis that the energy, financials and information technology sectors of the U.S. equity markets may outperform the broader

market in a rising interest rate environment, and that the utilities, consumer staples and health care sectors may outperform the broader market in a falling or flat interest rate environment. That investment thesis may be wrong. The assumed relationship may not in fact exist. Even if a relationship did exist at points in the past, it may not exist in the future. If the Index’s investment thesis is wrong, the Index’s Equity Allocation may perform no better than, and in fact may materially underperform, any other allocation that could be made among the equity sector ETFs or the broader market. Our offering of the notes is not an expression of our view about the validity of the Index’s investment thesis. You should form your own independent view about the validity of the Index’s investment thesis in connection with your evaluation of any investment linked to the Index.

Even If The Index’s Investment Thesis Has Merit, The Effects Of The Relationship Between The Prevailing Interest Rate Environment And Different Sectors Of The U.S. Equity Market May Be Weak. At best, interest rates are only one factor of many that may relate to the performance of different sectors of the U.S. equity market. Even if there is a relationship between the prevailing interest rate environment and the relative performance of different sectors of the U.S. equity market, the resulting effects on the performance of the relevant equity sectors would hold true only if all other factors were held constant. In reality, other factors are not held constant, and other factors may overwhelm these effects. For example, even at a time of rising interest rates and strong economic growth, commodity prices may fall dramatically as a result of oversupply, causing the energy sector to perform poorly. Or even at a time of falling interest rates, the consumer staples sector may perform poorly because it is adversely affected by weak economic conditions.

Furthermore, as described in “Description of the Citi Radar^SM 3.5 Excess Return Index—Investment Thesis” in this index supplement, the Index’s investment thesis is predicated in part on an assumption about the relationship between the prevailing interest rate environment, on the one hand, and economic growth and consumer sentiment, on the other—namely, that a Rising interest rate environment is associated with economic growth and improving consumer sentiment, and that a Not Rising interest rate environment is associated with slowing economic growth and declining consumer sentiment. If that relationship is weak, then the relationship between the prevailing interest rate environment and the relative performance of different sectors of the U.S. equity market may also be weak.

There are reasons to expect that the assumed relationship between the prevailing interest rate environment and economic growth may not necessarily hold. For example, there have been many instances historically when there was strong economic growth and consumer sentiment even at a time of stable interest rates. In that environment, the Index would allocate exposure to the utilities, consumer staples and health care sectors, and those sectors may fail to benefit as much as other sectors from strong economic growth and consumer sentiment. Moreover, changes in interest rates may be a lagging indicator of economic conditions. When the Federal Reserve changes its interest rate policies, it is likely to have done so after many months of economic data indicating a change in economic conditions. This time lag is in addition to the time lag inherent in the calculation of the Rates Signal. For all of these reasons, there may be a lengthy period of disconnect between economic conditions and the prevailing interest rate environment identified by the Rates Signal.

If the relationship between the prevailing interest rate environment and the relative performance of the selected equity sector ETFs is weak, the selected equity sector ETFs included in the Index’s Equity Allocation may fail to meaningfully outperform, and may in fact materially underperform, any other allocation that could be made among the equity sector ETFs or the broader market. At the same time, the Index would be subject to the negative effects of the excess return deduction and index fee. Those negative effects may be significantly greater than any positive effects resulting from the implementation of the Index’s investment thesis.

Even If The Index’s Investment Thesis Has Merit, The Index May Not Effectively Implement That Thesis. Even if a relationship exists between the prevailing interest rate environment and the relative performance of different sectors of the U.S. equity market, the particular rules that make up the Index methodology may not effectively capitalize on that relationship. The following is a non-exhaustive list of reasons why the Index may not effectively implement its investment thesis.

environment is, in part, that these sectors provide basic necessities and so may be less sensitive than other sectors to an economic downturn that may accompany a falling interest rate environment. That rationale is less applicable in a flat interest rate environment, which may not be accompanied by an economic downturn. If a flat interest rate environment prevails for an extended period of time and is accompanied by strong economic growth, the utilities, consumer staples and health care sectors that make up the Equity Allocation in that environment may significantly underperform the broader market.

The Index Only Seeks To Partially Implement Its Investment Thesis, And As A Result May Perform Poorly Even If Its Investment Thesis Proves Correct. At any point in time, the Index is likely to have a significant allocation to the Treasury Futures Allocation and/or the Cash Allocation. That allocation is intended to help the Index maintain its volatility target of 3.5%, and is not in furtherance of its investment thesis. In fact, because the U.S. Treasury note futures indices are likely to be adversely affected by rising interest rates, the allocation to the Treasury Futures Allocation may run counter to the Index’s investment thesis. For example, in a Rising interest rate environment, even if the equity sector ETFs that are included in the Selected Portfolio perform favorably, that performance is likely to be offset, and perhaps more than offset, by the decline in the level of the applicable U.S. Treasury note futures index that would result from the rise in interest rates. As a result, even if the Index’s investment thesis proves to be correct, the Index may have poor performance or even decline as a result of its significant allocation to the Treasury Futures Allocation and/or Cash Allocation.

The Index Is Likely To Significantly Underperform Equities In Rising Equity Markets. The Index is likely to have a significant allocation to the Treasury Futures Allocation and/or Cash Allocation at all times. Only a portion of the Selected Portfolio will be allocated to the Equity Allocation at any point in time. As a result, even if the Index’s investment thesis is correct, and even if the Index effectively implements that thesis at a time when equity markets are rising, the Index may nevertheless materially underperform an alternative investment in the equity sector ETFs that is not based on that thesis but that is fully allocated to the equity sector ETFs.

The portion of the Index’s Invested Allocation that is allocated to the Equity Allocation will be equal to the Index’s target volatility of 3.5% divided by the annualized volatility of the current Equity Allocation over the prior six months. The volatility of the Equity Allocation is likely to significantly exceed 3.5%. The higher the volatility of the Equity Allocation, the lower the degree of exposure the Index will have to the Equity Allocation. For example, if the volatility of the current Equity Allocation were to be 20% over the prior six months, the Invested Allocation would consist 17.5% of the Equity Allocation and 82.5% of the Treasury Futures Allocation. The

exposure of the overall Selected Portfolio to the Equity Allocation would then be subject to further reduction if the volatility of the Invested Allocation over the prior month were to exceed 3.5%. The allocation to the Invested Allocation will be equal to the Index’s target volatility of 3.5% divided by the annualized volatility of the Invested Allocation over the prior month. For example, if the volatility of the Invested Allocation were to be 10% over the prior month, then the Selected Portfolio would consist 35% of the Invested Allocation and 65% of the Cash Allocation. As a result, the overall allocation to the Equity Allocation in this scenario would be equal to 35% of 17.5%, or 6.125%.

We expect that it will frequently be the case that the allocations to the Treasury Futures Allocation and/or Cash Allocation within the Selected Portfolio will be greater than the allocation to the Equity Allocation.

The Equity Sector ETFs That May Be Included In The Equity Allocation Do Not Cover All Sectors Or Segments Of The U.S. Equity Market. The Global Industry Classification Standard (“GICS”), which defines the sectors tracked by the equity sector ETFs, divides the U.S. equity market into eleven sectors. Only six equity sector ETFs are eligible to be included in the Equity Allocation. Moreover, the equity sector ETFs that are eligible to be included in the Equity Allocation only include stocks from the large capitalization segment of the U.S. equity market, as represented by the S&P 500^® Index. As a result, a significant portion of the U.S. equity market is not eligible for inclusion in the Equity Allocation. The sectors represented by the six equity sector ETFs that are eligible for inclusion in the Equity Allocation may not exhibit as strong a relationship with the prevailing interest rate environment as the GICS sectors that are not eligible for inclusion or as the small capitalization segment of the U.S. equity market, and those other equity sectors or the small capitalization segment may have better performance than the six large capitalization sectors that are eligible for inclusion.

The Equity Sector ETFs In The Equity Allocation May Offset Each Other. At any given time, the Equity Allocation will consist of three equity sector ETFs. Even if the relationships posited by the Index’s investment thesis exist between the prevailing interest rate environment and one or two of the equity sectors represented in the Equity Allocation, that relationship may not exist for the other equity sector(s). Even if one or two of those equity sector ETFs performs favorably, one or two others may perform unfavorably, partially or fully offsetting, or more than offsetting, the performance of the favorably performing equity sector ETF(s). The Index might have performed more favorably if it included fewer equity sector ETFs in the Equity Allocation.

The Index Is Likely To Have Significant Exposure To The Treasury Futures Allocation, Which Has Limited Return Potential And Significant Downside Potential, Particularly In Times Of Rising Interest Rates. Each U.S. Treasury note futures index has limited return potential, which in turn limits the return potential of the Index. However, each U.S. Treasury note futures index has significant downside potential, particularly in a “Rising” interest rate environment. Although U.S. Treasury notes themselves are generally viewed as safe assets, each U.S. Treasury note futures index tracks the value of a futures contract on U.S. Treasury notes, which may be subject to significant fluctuations and declines. In particular, the value of a futures contract on a U.S. Treasury note is likely to decline if there is a general rise in interest rates, as the rise in interest rates would reduce the value of the underlying U.S. Treasury notes. In addition, the value of a futures contract on U.S. Treasury notes is likely to decline by more than the decline in the value of the underlying U.S. Treasury notes at a time of rising interest rates, because the futures contract will also be adversely affected by an increase in the implicit financing cost discussed above. As a result, even if the Index’s investment thesis were correct and the equity sector ETFs selected in a “Rising” interest rate environment perform favorably in that environment, that favorable performance is likely to be at least partially offset, and may be more than offset, by unfavorable performance of the applicable U.S. Treasury note futures index.

The Index May Have Significant Exposure To The Cash Allocation, On Which No Interest Or Other Return Will Accrue. At any time when the Selected Portfolio has less than a 100% allocation to the Invested Allocation, the difference will be hypothetically allocated to uninvested cash (the Cash Allocation) and will not accrue any interest or other return. A significant allocation to the Cash Allocation will significantly reduce the Index’s potential for gains. In addition, the index fee will be deducted from the entire Index, including the portion allocated to the Cash Allocation. As a result, after taking into account the deduction of the index fee, any portion of the Index that is allocated to the Cash Allocation will experience a net decline at a rate equal to the index fee. In general, the Cash Allocation is likely to be greatest at a time when the one-month volatility of the equity sector ETFs making up the actual Equity Allocation over the preceding month has increased significantly from the six-month volatility of the current Equity Allocation.

The Excess Return Deduction Will Be A Significant Drag On Index Performance. The performance of each U.S. Treasury note futures index is expected to reflect changes in the value of the underlying U.S. Treasury notes, as reduced by an implicit financing cost. In addition, for purposes of the Index, the performance of each equity sector ETF will be calculated on a daily basis after deducting a rate equal to the federal funds effective rate from its actual total return performance. We refer to this deduction, together with the implicit financing cost in the performance of each U.S. Treasury note futures index, as the “excess return deduction”. The excess return deduction will cause the performance of each U.S. Treasury note futures index to be significantly less than the performance of the underlying U.S. Treasury notes, and will cause the performance of each equity sector ETF, as measured for purposes of the Index, to be significantly less than its actual performance. The excess return deduction means that the Selected Portfolio will not have positive returns unless the relevant U.S. Treasury notes and/or equity sector ETFs appreciate sufficiently to offset the excess return deduction. Because of the excess return deduction, the Selected Portfolio may have negative returns even if the relevant U.S. Treasury notes and/or equity sector ETFs appreciate.

The excess return deduction will place a drag on the performance of the Index, offsetting any appreciation of the U.S. Treasury notes underlying the applicable U.S. Treasury note futures index and the equity sector ETFs that make up the Equity Allocation, exacerbating any depreciation and causing the value of the Selected Portfolio to decline steadily if the value of those U.S. Treasury notes and/or equity sector ETFs remains relatively constant.

The Index Fee Will Adversely Affect Index Performance. An index fee of 0.75% per annum is deducted in the calculation of the Index. The negative effects of the index fee on Index performance will be in addition to the negative effects of the excess return deduction described above.

The Index May Fail To Maintain Its Volatility Target And May Experience Large Declines As A Result. The Index adjusts the Selected Portfolio’s exposure between the Equity Allocation and the Treasury Futures Allocation, and between the Invested Allocation and the Cash Allocation, as often as daily in an attempt to maintain a trailing one-month volatility target of 3.5%. Because this exposure adjustment is backward-looking based on historical volatility, there may be a significant time lag before a sudden increase in volatility of the Equity Allocation is sufficiently reflected in the trailing volatility measures used by the Index to result in a meaningful reduction in exposure to the Equity Allocation. In the meantime, the Index may experience significantly more than 3.5% volatility and, if the increase in volatility is accompanied by a decline in the value of the Invested Allocation, the Index may incur significant losses.

Because The Notes Provide For Repayment Of The Principal Amount At Maturity Regardless Of The Performance Of The Index, You May Not Receive A Meaningful Incremental Benefit From The Index’s Volatility-Targeting Feature Even Though You Will Be Subject To Its Significant Drawbacks. One potential benefit of the Index’s volatility-targeting feature is that it may reduce the potential for large Index declines in volatile equity markets. However, that reduced potential for large Index declines comes at a price: as discussed above, the volatility-targeting feature is likely to result in a significant allocation to the Treasury Futures Allocation and/or the Cash Allocation, significantly reducing the potential for Index gains if the Equity Allocation performs favorably. Because the notes provide for repayment of the principal amount at maturity even if the Index experiences a large decline, any reduced potential for large Index declines resulting from the volatility-targeting feature may not provide a meaningful incremental benefit to an investor in the notes. Investors in the notes will, however, be fully subject to the drawbacks of the volatility-targeting feature, in the form of the reduced participation in rising equity markets and the other risks described in this section. As a result, you should understand that any benefit you receive from the Index’s volatility-targeting feature may be outweighed by its drawbacks.

The Daily Volatility-Targeting Feature May Cause The Index To Perform Poorly In Temporary Market Crashes. A temporary market crash is an event in which the volatility of the Equity Allocation spikes suddenly and its value declines sharply over a short period of time, but the decline is short-lived and the Equity Allocation soon recovers its losses. In this circumstance, although the value of the Equity Allocation after the recovery may return to its value before the crash, the level of the Index may not fully recover its losses. This is because of the time lag that results from using a look-back period in the second stage of the Index’s volatility-targeting feature of one month. Because of the time lag, the Index may not meaningfully reduce its exposure to the Invested Allocation until the crash has already occurred, and by the time the reduced exposure does take effect, the recovery may have already begun. For example, if the Index has 50% exposure to the decline in the Invested Allocation, and then reduces its exposure so that it has only 20% exposure to the recovery, the Index will end up significantly lower after the crash and recovery than it was before the crash.

The Performance Of The Index Will Be Highly Sensitive To The Specific Parameters By Which It Is Calculated. The Index is calculated pursuant to a rules-based methodology that contains a number of specific parameters. These parameters will be significant determinants of the performance of the Index. For example, the Rates Signal will indicate a Rising interest rate environment only if there have been three consecutive month-over-month increases in the average daily rate of 3-month U.S. dollar LIBOR for the applicable month; the allocation between the Equity Allocation and the Treasury Futures Allocation is based on the annualized volatility of the current Equity Allocation over an arbitrary look-back period of approximately six months; the allocation between the Invested Allocation and the Cash Allocation is based on the annualized volatility of the Invested Allocation over an arbitrary look-back period of approximately one month; and the Equity Allocation can be made up of only three out of six selected equity sector ETFs, and only one of two U.S. Treasury note futures indices, at any one time. There is nothing inherent in any of these specific parameters that necessarily makes them the right specific parameters to use for the Index. If the Index had used different parameters, the Index might have achieved significantly better returns.

The Index Will Be Calculated Pursuant To A Set Of Fixed Rules And Will Not Be Actively Managed. If the Index performs poorly, the Index Administrator will not change the rules in an attempt to improve performance. The Index tracks the hypothetical performance of the rules-based investment methodology described under “Description of the Citi Radar^SM 3.5 Excess Return Index” in this index supplement. The Index will not be actively managed. If the rules-based investment methodology tracked by the Index performs poorly, the Index Administrator will not change the rules in an attempt to improve performance. Accordingly, an investment linked to the Index is not like an investment in a mutual fund. Unlike a mutual fund, which could be actively managed by the fund manager in an attempt to maximize returns in changing market conditions, the Index rules will remain unchanged, even if those rules might prove to be ill-suited to future market conditions.

The Index Has Limited Actual Performance Information. The Index launched on August 25, 2020. Accordingly, the Index has limited actual performance data. Because the Index is of recent origin with limited performance history, an investment linked to the Index may involve a greater risk than an investment linked to one or more indices with an established record of performance. A longer history of actual performance may have provided more reliable information on which to assess the validity of the Index’s hypothetical investment methodology. However, any historical performance of the Index is not an indication of how the Index will perform in the future.

Hypothetical Back-Tested Index Performance Information Is Subject To Significant Limitations. All information regarding the performance of the Index prior to August 25, 2020 is hypothetical and back-tested, as the Index did not exist prior to that time. It is important to understand that hypothetical back-tested Index performance information is subject to significant limitations, in addition to the fact that past performance is never a guarantee of future performance. In particular:

As a result of the above, the hypothetical back-tested Index performance information may not reflect how the Index would have performed if the two equity sector ETFs had tracked their target sectors as currently defined.

It is impossible to predict whether the Index will rise or fall. The actual future performance of the Index may bear no relation to the historical or hypothetical back-tested levels of the Index.

Changes To The GICS Sectors Upon Which The Equity Sector ETFs Are Based May Adversely Affect The Performance Of The Index. Changes are made from time to time to the GICS sector classification system, which is used to define the sector that each equity sector ETF tracks. Any changes made in the future could materially change the composition of the sector tracked by one or more equity sector ETFs, which could result in materially worse Index performance than if the change had not been made.

There Are Drawbacks Associated With Tracking The Value Of ETFs Rather Than The Underlying Indices That The ETFs Seek To Track. The Equity Allocation Will Be Composed Of ETFs. Each ETF seeks to track the performance of its underlying index before giving effect to fees and expenses of the ETF. After giving effect to these fees and expenses, the performance of each ETF is likely to be less favorable than the performance of the underlying index that it tracks. In addition, the price of the shares of each ETF may not perfectly track the performance of its underlying index or its net asset value per share. An ETF may not hold all of the assets that constitute its underlying index or may hold assets and/or derivative contracts not included in that underlying index. Moreover, the trading price of an ETF is determined by market supply and demand and can deviate from the value of the ETF’s assets. As a result, in certain circumstances, the performance of an ETF may diverge significantly from, and may be less favorable than, the performance of its underlying index. In addition, corporate actions with respect to the equity securities constituting an underlying index or held by its ETF (such as mergers and spin-offs) may impact the variance between the performances of the ETF and its underlying index.

During periods of market volatility, securities underlying an ETF may be unavailable in the secondary market, market participants may be unable to calculate accurately the net asset value per share of an ETF and the liquidity of an ETF may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares in an ETF. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares of an ETF. As a result, under these circumstances, the market value of shares of an ETF may vary substantially from its net asset value per share. For all

of the foregoing reasons, the performance of an ETF may not correlate with the performance of its underlying index or its net asset value per share, which could materially and adversely affect the performance of the Index.

The Index Administrator And Index Calculation Agent, Which Is Our Affiliate, May Exercise Judgments Under Certain Circumstances In The Calculation Of The Index. Although the Index is rules-based, there are certain circumstances under which the Index Administrator or Index Calculation Agent may be required to exercise judgment in calculating the Index, including the following:

Citigroup Global Markets Limited may be required to make similar types of judgments in its capacity as index administrator and calculation agent for the U.S. Treasury note futures indices.

Investing In The Notes Is Not The Same As Directly Owning The Equity Sector ETFs, U.S. Treasury note futures contracts or cash included in the Selected Portfolio. The Selected Portfolio is described as a hypothetical investment portfolio because there is no actual portfolio of assets to which any investor is entitled or in which any investor has any ownership or other interest. The Index is merely a mathematical calculation that is performed by reference to hypothetical positions in the equity sector ETFs, U.S. Treasury notes futures index and cash included in the Selected Portfolio, and the other Index rules.

DESCRIPTION OF THE NOTES

The following description of the general terms of the Notes supplements the general terms and provisions set forth in the accompanying prospectus supplement and prospectus. If any specific information regarding the Notes in this index supplement is inconsistent with the more general terms described in the accompanying prospectus supplement and prospectus, you should rely on the information in this index supplement.

The pricing supplement applicable to a particular issuance of Notes will contain the specific terms of those Notes. If any information in the applicable pricing supplement is inconsistent with this index supplement, you should rely on the information in the applicable pricing supplement. The applicable pricing supplement may also add, update or change information contained in this index supplement or in the accompanying prospectus supplement and prospectus. It is important for you to consider carefully the information contained in this index supplement together with the information contained in the applicable pricing supplement and the accompanying prospectus supplement and prospectus before investing in the Notes.

General

The notes offered under this index supplement (the “Notes”) are senior unsecured debt securities issued by Citigroup Global Markets Holdings Inc. under the senior debt indenture described in the accompanying prospectus supplement and prospectus. Any payments due on the Notes are fully and unconditionally guaranteed by Citigroup Inc. The Notes will constitute part of the senior debt of Citigroup Global Markets Holdings Inc. and will rank equally with all other unsecured and unsubordinated debt of Citigroup Global Markets Holdings Inc. The guarantee of payments due on the Notes will constitute part of the senior debt of Citigroup Inc. and will rank equally with all other unsecured and unsubordinated debt of Citigroup Inc.

The particular payment terms of the Notes will be set forth in the applicable pricing supplement and will be linked to the performance of the Citi Radar^SM 3.5 Excess Return Index (the “Index”). The Index is described in “Description of the Citi Radar^SM 3.5 Excess Return Index” below.

The Notes provide for the repayment of the stated principal amount at maturity. If so specified in the applicable pricing supplement, the Notes offer the possibility of an additional payment at maturity (other than any coupon payment, if specified in the applicable pricing supplement) based on the performance of the Index. The stated principal amount of each Note will be specified in the applicable pricing supplement.

In addition to the risks associated with the performance of the Index, all payments due on the Notes are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc., as guarantor of any payments due on the Notes. If Citigroup Global Markets Holdings Inc. and Citigroup Inc. default on their obligations under the Notes, you may not receive any payment owed to you, including the repayment of the stated principal amount of your Notes at maturity.

Any potential payment on the Notes that depends on the performance of the Index will be based on the Closing Level of the Index on one or more dates specified in the applicable pricing supplement (each, a “Valuation Date”), subject to the specific terms set forth in the applicable pricing supplement. If any scheduled Valuation Date is not an Index Business Day, such Valuation Date will be postponed to the next succeeding Index Business Day.

An “Index Business Day” is a day (1) on which commercial banks and foreign exchange markets are scheduled to be open for general business (including dealings in foreign exchange and foreign exchange currency deposits) in New York City and (2) which is also a Scheduled Trading Day for each of the Constituents.

The term “Scheduled Trading Day” has, in respect of each Constituent, the meaning specified under “Description of the Citi Radar^SM 3.5 Excess Return Index” below.

The term “Constituent” has the meaning specified under “Description of the Citi Radar^SM 3.5 Excess Return Index” below.

Maturity

The notes will mature on the date specified in the applicable pricing supplement (the “Maturity Date”). If the Maturity Date falls on a day that is not a New York Business Day, the payment to be made on the Maturity Date will be made on the next succeeding New York Business Day with the same force and effect as if made on the Maturity Date, and no interest will accrue as a result of such delayed payment. If a Notes Disruption Event occurs on the Valuation Date (or if there is more than one Valuation Date, on the final Valuation Date), then the Maturity Date will be postponed to the third New York Business Day after the Final Determination Date with respect to such Valuation Date. In addition, if the originally scheduled Valuation Date (or if there is more than one Valuation Date, the originally scheduled final Valuation Date) is not an Index Business Day and such Valuation Date is postponed so that it falls fewer than three New York Business Days prior to the Maturity Date, the Maturity Date will be postponed to the third New York Business Day after such Valuation Date as postponed.

“New York Business Day” means any day that is not a Saturday, a Sunday or a day on which the securities exchanges, bank institutions or trust companies in the City of New York are authorized or obligated by law or executive order to close.

Notes Calculation Agent

The “Notes Calculation Agent” for each issuance of Notes will be our affiliate, Citigroup Global Markets Inc. (“CGMI”), or any successor appointed by us, unless otherwise specified in the applicable pricing supplement. The Notes Calculation Agent will make the determinations specified in this index supplement or in the applicable pricing supplement. All determinations made by the Notes Calculation Agent will be at the sole discretion of the Notes Calculation Agent and will, in the absence of manifest error, be conclusive for all purposes and binding on Citigroup Global Markets Holdings Inc., Citigroup Inc. and the holders of the Notes. The Notes Calculation Agent is obligated to carry out its duties and functions in good faith and using its reasonable judgment.

Determining the Closing Level of the Index

The “Closing Level” of the Index means, on any date of determination, the Index Level (as defined under “Description of the Citi Radar^SM 3.5 Excess Return Index” below) for such day as published by the Index Calculation Agent, subject to the terms described under “—Discontinuance of the Index” below. If the Index Level is not published by the Index Calculation Agent for any date of determination, or if the Notes Calculation Agent determines that a Market Disruption Event exists with respect to any Constituent on any date of determination, the Notes Calculation Agent will calculate the Closing Level of the Index in respect of that date of determination in good faith in accordance with the formula for and method of calculating the Index last in effect prior to commencement of the Market Disruption Event or failure to publish, using:

(i) for any Constituent with respect to which a Market Disruption Event does not occur on that date of determination, the Constituent Closing Level of such Constituent on that date of determination; and

(ii) for each Constituent with respect to which a Market Disruption Event occurs or is continuing on that date of determination, the Constituent Closing Level of such Constituent on the immediately succeeding Scheduled Trading Day for such Constituent on which no Market Disruption Event occurs or is continuing with respect to such Constituent, unless such Scheduled Trading Day has not occurred by the fifth Scheduled Trading Day for such Constituent following that date of determination (the “Backstop Date”), in which case the Notes Calculation Agent will use an alternative Constituent Closing Level for such Constituent determined using its good faith estimate of the Constituent Closing Level of that Constituent as of such Backstop Date.

For any date of determination on which the Index Level is not published or a Market Disruption Event exists, the Notes Calculation Agent will, following that date of determination, calculate the Closing Level in respect of that date, and the Notes Calculation Agent will reflect in such Closing Level the index fee described under “Description of the Citi Radar^SM 3.5 Excess Return Index” to the date of such calculation. If the Notes Calculation Agent determines that a Market Disruption Event exists with respect to any Constituent on a Valuation Date (such event, a “Notes Disruption Event”), the date on which the Closing Level of the Index in respect of such Valuation Date is finally determined (i.e., the first date on which the Constituent Closing Level has been determined for all

Constituents in respect of such Valuation Date) is referred to as the “Final Determination Date” for such Valuation Date.

The term “Constituent Closing Level” means (i) in respect of each Constituent that is an equity sector ETF, the closing price of such equity sector ETF on the exchange on which it is traded and (ii) in respect of each Constituent that is a U.S. Treasury note futures index, the official closing level of such index, in each case, except as otherwise provided in the definition of “Closing Level” above.

The term “Market Disruption Event” means, in respect of each Constituent, any event that would result in a Disrupted Day with respect to that Constituent, as described under “Description of the Citi Radar^SM 3.5 Excess Return Index” below.

Discontinuance of the Index

If the Index Administrator discontinues publication of the Index, and it or another entity (including CGMI) publishes a successor or substitute index that the Notes Calculation Agent determines, in its sole discretion, to be comparable to the discontinued Index, then the Closing Level of the Index thereafter will be determined by reference to the level of that index, which we refer to as a “Successor Index.” In such an event, the Notes Calculation Agent will, in its sole discretion, make any adjustment to any level of the Index or the Successor Index used for purposes of the Notes as it may deem appropriate in order to account for the effect of the substitution.

If the Index Administrator discontinues publication of the Index prior to, and such discontinuance is continuing on, a Valuation Date and the Notes Calculation Agent determines, in its sole discretion, that no Successor Index is available at such time, then the Notes Calculation Agent will determine a substitute Closing Level for the Index for such date. Such Closing Level will be determined by the Notes Calculation Agent in accordance with the formula for calculating the Index last in effect prior to such discontinuance, except that, at all times after such discontinuance, (i) the Equity Allocation will consist of a basket of all six equity sector ETFs eligible for inclusion in the Index, equally weighted at the time of discontinuance of the Index but without further rebalancing thereafter and (ii) the Treasury Futures Allocation will consist of the Citi Interest Rate 2Y U.S. Treasury Futures Market Tracker Index. In such an event, the Closing Level of the Index so determined will cease to reflect the Index’s portfolio selection methodology. For purposes of clarity, if the Index Administrator discontinues publication of the Index and the Notes Calculation Agent is required to calculate a substitute Closing Level for the Index, the Notes Calculation Agent will make that calculation applying all of the current features of the Index, including the volatility targeting, the excess return deduction and the index fee, with the exception that the components of the Equity Allocation and Treasury Futures Allocation will become fixed as described above.

If the discontinuance of the Index was the result of a material modification or permanent cancellation of a Constituent, and such modification or cancellation is continuing on a Valuation Date, or if a Constituent is otherwise unavailable on a Valuation Date, then the Notes Calculation Agent will determine the Constituent Closing Level for such Constituent with respect to any date for which a Constituent Closing Level of such Constituent may be required using its good faith estimate of the closing price or level of that Constituent on each such date. Notwithstanding these alternative arrangements, discontinuance of the publication of the Index may adversely affect the value of the Notes.

Coupon

The Notes will not pay a coupon unless the applicable pricing supplement specifically provides otherwise. If the applicable pricing supplement specifies that the Notes will pay a coupon, the Notes will pay a coupon at the per annum rate specified in the applicable pricing supplement, which may be a fixed rate or may be determined by reference to the performance of the Index or otherwise. If the applicable pricing supplement provides that the Notes will pay a coupon, holders of the Notes will receive the applicable coupon payment on the coupon payment dates specified in the applicable pricing supplement (each, a “Coupon Payment Date”). If the per annum rate varies over the term of the Notes based on the performance of the Index or otherwise, the per annum rate for each Coupon Payment Date will be determined in the manner and on the Valuation Date specified in the applicable pricing supplement. Unless otherwise specified in the applicable pricing supplement, each coupon payment will be computed on the basis of a 360-day year of twelve 30-day months or, in the case of an incomplete month, the number of days elapsed. Unless otherwise specified in the applicable pricing supplement, the coupon payable on the

first Coupon Payment Date for an issuance of Notes will accrue from and including the issue date of such Notes to but excluding such first Coupon Payment Date, and the coupon payable on each succeeding Coupon Payment Date for an issuance of Notes will accrue from and including the immediately preceding Coupon Payment Date to but excluding such succeeding Coupon Payment Date.

Unless otherwise specified in the applicable pricing supplement, each coupon payment will be payable to the persons in whose names the Notes are registered at the close of business on the New York Business Day immediately preceding the applicable Coupon Payment Date (each a “Regular Record Date”), except that the final coupon payment will be payable to the persons who receive the payment at maturity. If any Coupon Payment Date is not a New York Business Day, the coupon payment to be made on that Coupon Payment Date will be made on the next succeeding New York Business Day with the same force and effect as if made on that Coupon Payment Date, and no interest will accrue as a result of delayed payment. If any coupon payment on the Notes depends on the Closing Level of the Index on a Valuation Date and such Valuation Date is postponed as provided under “—Determining the Closing Level of the Index” and the relevant Coupon Payment Date is specified as a fixed date, such coupon payment will be made on the later of (i) the third New York Business Day after such Valuation Date (or the last such Valuation Date, if two or more consecutive Scheduled Trading Days are each scheduled Valuation Dates), as postponed and (ii) the Coupon Payment Date.

Automatic Call

If specified in the applicable pricing supplement, an automatic call feature will apply to the Notes in the circumstances and on the date(s) specified in the applicable pricing supplement. If an automatic call is triggered, the Notes will be redeemed for a cash payment that will be determined as set forth in the applicable pricing supplement. The minimum amount of such cash payment will be equal to the stated principal amount per Note. The Notes will not be subject to an automatic call feature unless the applicable pricing supplement so provides.

Call Right

If specified in the applicable pricing supplement, we will have the right to call the Notes, in whole or in part, on terms specified in the applicable pricing supplement. If applicable, the pricing supplement will specify the dates on which we may call the Notes, the price at which we may call the Notes, the circumstances in which we may call the Notes and the payment to be made upon redemption. If any date on which we elect to redeem the Notes falls on a day that is not a New York Business Day, the payment to be made upon redemption will be made on the next succeeding New York Business Day with the same force and effect as if made on the original date of redemption, and no interest will accrue as a result of delayed payment. We will not have the right to call the Notes unless the applicable pricing supplement so provides.

If we have the right to call the Notes, the provisions set forth under “Description of the Notes—Optional Redemption, Repayment and Repurchase” in the accompanying prospectus supplement will apply, subject to the terms set forth in the applicable pricing supplement.

Holders of the Notes will not have the right to require us to redeem the Notes prior to maturity, unless otherwise specified in the applicable pricing supplement.

No Redemption at the Option of the Holder; Defeasance

The Notes will not be subject to redemption at the option of any holder prior to maturity and will not be subject to the defeasance provisions described in the accompanying prospectus under “Description of Debt Securities—Defeasance.”

Events of Default and Acceleration

In case an event of default (as described in the accompanying prospectus) with respect to any issuance of Notes shall have occurred and be continuing, the amount declared due and payable upon any acceleration of the Notes will be determined by the Calculation Agent and will equal, for each Note, the amount to be received on the Maturity Date, calculated using the Closing Level of the Index as though the date of acceleration were the Valuation Date (or the final Valuation Date if there is more than one Valuation Date). For purposes of the immediately preceding

sentence, if the applicable pricing supplement specifies that the Notes will pay a coupon, your final coupon payment will reflect the portion of the coupon that has accrued (or will be prorated) from and including the immediately preceding Coupon Payment Date on which a coupon payment was made (if required) (or the issue date, if there is no such Coupon Payment Date) to but excluding the date of acceleration.

In case of default under the Notes, whether in the payment of a coupon or any other payment due under the Notes, no interest will accrue on such overdue payment either before or after the Maturity Date.

Paying Agent, Trustee and CUSIP

Citibank, N.A. will serve as paying agent and registrar for the Notes and will also hold the global notes representing each issuance of Notes as custodian for DTC. The Bank of New York Mellon will serve as trustee for the Notes.

The CUSIP number for each issuance of Notes will be set forth in the applicable pricing supplement.

DESCRIPTION OF THE CITI RADAR^SM 3.5 EXCESS RETURN INDEX

Overview

The Citi Radar^SM 3.5 Excess Return Index (the “Index”) was developed by Citigroup Global Markets Limited (the “Index Administrator” and “Index Calculation Agent”). The description of the Index included in this section is based on rules formulated by the Index Administrator (the “Index Rules”), which are attached as an annex to this Index Supplement. The Index launched on August 25, 2020 and, therefore, has a limited performance history.

The Index is designed to track the hypothetical performance of the rules-based investment methodology described in this section. The Index methodology is premised on the idea that there is a relationship between the prevailing interest rate environment in the United States and the relative performance of different sectors of the U.S. equity and Treasury markets. Based on that premise, the Index seeks to determine on a daily basis whether the United States is in a “Rising” interest rate environment or a “Not Rising” interest rate environment. If the Index determines that there is a “Rising” interest rate environment, the Index will allocate exposure to exchange-traded funds (“ETFs”) representing sectors of the U.S. equity market that, according to the Index’s investment thesis, may outperform the broader market in a rising interest rate environment. If, on the other hand, the Index determines that there is a “Not Rising” interest rate environment, the Index will allocate exposure to different ETFs representing sectors of the U.S. equity market that, according to the Index’s investment thesis, may outperform the broader market in a falling or flat interest rate environment. In an attempt to maintain a volatility target of 3.5%, the Index will also allocate exposure to U.S. Treasury note futures and, potentially, to uninvested cash. Collectively, these allocations – to the selected equity sector ETFs, U.S. Treasury note futures and uninvested cash – make up a hypothetical investment portfolio. The performance of the Index will reflect the performance of that hypothetical investment portfolio, as adjusted daily in response to the observed interest rate environment and pursuant to the volatility targeting feature described below, and subject to the excess return deduction and index fee described below.

The Index determines whether the prevailing interest rate environment is “Rising” or “Not Rising” on each Index Business Day by observing the average rate of 3-month U.S. dollar LIBOR for each month in the immediately preceding four months. If the average rate of 3-month U.S. dollar LIBOR increased from each month to the next in that four-month period, then the Index will determine that there is a “Rising” interest rate environment. In all other circumstances, the Index will determine that there is a “Not Rising” interest rate environment. See “—Rates Signal” below.

The following table lists the equity sector ETFs and U.S. Treasury note futures index to which the Index will allocate exposure in each observed interest rate environment. The table also indicates the possibility that the Index will have exposure to uninvested cash.

We refer to the hypothetical investment portfolio tracked by the Index at any given time as the “Selected Portfolio” at that time. The selected equity sector ETFs together make up a hypothetical “Equity Allocation” in the

Selected Portfolio and will be equally weighted with each other. The applicable U.S. Treasury note futures index makes up a hypothetical “Treasury Futures Allocation”. We refer to the overall allocation to the Equity Allocation and the Treasury Futures Allocation together as the “Invested Allocation” within the Selected Portfolio. In addition to these allocations, the Selected Portfolio may have a hypothetical allocation to uninvested cash, which we refer to as the “Cash Allocation”. No interest or other return will accrue on the Cash Allocation.

The Index determines how much exposure to allocate to each of the Equity Allocation, the Treasury Futures Allocation and the Cash Allocation on a daily basis in a manner designed to maintain a target volatility of the Index of 3.5%. This volatility-targeting feature is applied in two stages. First, the Index will allocate exposure between the Equity Allocation and the Treasury Futures Allocation within the Invested Allocation based on the volatility of the current Equity Allocation over the prior six months, with higher volatility resulting in a lower Equity Allocation, and vice versa. Second, the Index will allocate exposure between the Invested Allocation and the Cash Allocation based on the volatility of the Invested Allocation over the prior one month. In this second stage, the Index will, if necessary, reduce exposure to the Invested Allocation and increase exposure to the Cash Allocation (which has no volatility) in an attempt to maintain a rolling one-month Selected Portfolio volatility of 3.5%. See “—Selection and Composition of the Selected Portfolio” below.

The chart below illustrates the composition of four hypothetical Selected Portfolios, assuming various combinations of the Rates Signal, the trailing six-month volatility of the current Equity Allocation and the trailing one-month volatility of the Invested Allocation. The chart is intended solely for the purpose of illustrating how various allocations together make up a Selected Portfolio, depending on the Rates Signal, the trailing six-month volatility of the current Equity Allocation and the trailing one-month volatility of the Invested Allocation. It is not an indication of what the composition of the Selected Portfolio may be at any given point in time. The chart refers to each equity sector ETF by its ticker symbol, which can be found in the table above.

For information about the equity sector ETFs, see “Information About the Equity Sector ETFs” in this index supplement.

For information about the U.S. Treasury note futures indices, see “Description of the U.S. Treasury Note Futures Indices” in this Index Supplement. As discussed in that section, each U.S. Treasury note futures index

tracks the performance of a hypothetical investment, rolled quarterly, in a near-maturity U.S. Treasury note futures contract. A U.S. Treasury note futures contract is a contract for the purchase of U.S. Treasury notes with maturities falling within a specified range on a fixed date in the future. Accordingly, the value of a U.S. Treasury note futures contract will fluctuate with changes in the market value of the underlying U.S. Treasury notes. In general, the value of a U.S. Treasury note will fall as market interest rates rise, and rise as market interest rates fall. However, the value of a U.S. Treasury note futures contract will also fluctuate based on factors that are unique to a futures contract, such as supply and demand in the futures market, the time remaining to the maturity of the futures contract and market interest rates over the term of the contract. These factors are likely to cause a position in a U.S. Treasury note futures contract to reflect an implicit financing cost, which will lower the return on the futures contract as compared to a direct investment in the underlying U.S. Treasury notes. Accordingly, we expect the performance of each U.S. Treasury note futures index to generally reflect changes in the value of the underlying U.S. Treasury notes, as reduced by an implicit financing cost. We expect the implicit financing cost to rise if market interest rates rise.

In determining the performance of the Index, a rate equal to the federal funds effective rate will be deducted from the daily performance of each equity sector ETF. We refer to this deduction, together with the implicit financing cost reflected in each U.S. Treasury note futures index, as the “excess return deduction”. The excess return deduction is likely to cause the performance of the Selected Portfolio as measured for purposes of the Index to be significantly less than the actual performance of the equity sector ETFs and the U.S. Treasury notes underlying the U.S. Treasury futures that make up the Selected Portfolio. The impact of the excess return deduction will increase if market interest rates rise. The performance of the Index will also be reduced on a daily basis by an index fee of 0.75% per annum.

The Index methodology is subject to important risks. These risks are described in the section “Key Risks Relating to the Index” in this Index Supplement. A few of the key risks are briefly summarized below:

For more information about these and other risks associated with the Index, you should carefully review the section “Key Risks Relating to the Index” in this Index Supplement.

The Selected Portfolio is a hypothetical investment portfolio. There is no actual portfolio of assets to which any investor is entitled or in which any investor has any ownership or other interest. The Index is merely a mathematical calculation that is performed by reference to hypothetical positions in the Equity Allocation, Treasury Futures Allocation and Cash Allocation and the other Index Rules, as described in this section.

The Index Rules, which are attached as Annex A to this Index Supplement, set forth the specific rules governing the Index. This description of the Index is only a summary of the Index Rules. You should understand that this summary does not describe the mathematical terms used in calculating the Index, and as a result is more general than the precise mathematical formulations used to calculate the Index. The mathematical calculation of the Index is described in the Index Rules. The Index will be governed by and calculated in accordance with the mathematical

and other terms set forth in the Index Rules, and not this description of the Index. If this description of the Index conflicts with the Index Rules, the Index Rules control.

Investment Thesis

The Index methodology is premised on the idea that there is a relationship between the prevailing interest rate environment in the United States and the relative performance of different sectors of the U.S. equity market. Specifically, the Index methodology seeks to implement the thesis that the energy, financials and information technology sectors of the U.S. equity markets may outperform the broader market in a rising interest rate environment, and that the utilities, consumer staples and health care sectors may outperform the broader market in a falling or flat interest rate environment.

That thesis is, in turn, based on the following ideas:

The ideas stated above in this section underlie the Index methodology. We describe them not because we necessarily believe them to be true or valid, but so that it is clear what the ideas underlying the Index methodology are, and so that you can evaluate for yourself whether you believe them to have merit. You should not invest in any investment linked to the Index based on the description above. You should invest in any investment linked to the Index only after making an independent evaluation of the Index’s investment thesis and the manner in which it seeks to implement that thesis.

It is important to understand that, at best, interest rates are only one factor of many that may relate to the performance of different sectors of the U.S. equity market. Even if the relationships described above exist, the effects described above would hold true only if all other factors were held constant. In reality, other factors are not held constant, and other factors may overwhelm the effects described above. For example, even at a time of rising interest rates and strong economic growth, commodity prices may fall dramatically as a result of oversupply, causing the energy sector to perform poorly. Moreover, it is important to understand that the Index methodology does not distinguish between a falling and a flat interest rate environment. A flat interest rate environment will be treated as a “Not Rising” interest rate environment, even though the rationale stated above for allocating to the utilities, consumer staples and health care sectors in a “Not Rising” interest rate environment is more applicable in a falling interest rate environment than it is in a flat interest rate environment. For all of these reasons, the Index’s investment thesis may not be correct, or it may be too weak to be meaningful, or the Index may fail to effectively

implement its investment thesis. See “Key Risks Relating to the Index” for more information about the significant risks associated with the Index.

It is also important to understand that the Index only seeks to partially implement its investment thesis. At any given time, the Index is likely to have a significant allocation to the Treasury Futures Allocation and/or the Cash Allocation. These allocations are not in furtherance of the Index’s investment thesis, and in fact may run counter to the investment thesis, as discussed above.

Rationale for Allocation within Treasury Futures Allocation

The Treasury Futures Allocation will consist of the following:

The U.S. Treasury note futures indices are similar but for the maturities of the U.S. Treasury notes underlying the futures contracts that they track. See “Description of the U.S. Treasury Note Futures Indices” in this Index Supplement.

The Index allocates exposure to the Treasury Futures Allocation as part of its attempt to maintain its target volatility and will do so even at a time when the value of the Treasury Futures Allocation may be expected to fall, such as in a Rising interest rate environment. Although the Treasury Futures Allocation is not in furtherance of the Index’s investment thesis, the Selected Portfolio is likely to have a significant allocation to the Treasury Futures Allocation at all times.

The Index attempts to optimize the performance of the Treasury Futures Allocation by allocating to shorter-dated U.S. Treasury note futures in a Rising interest rate environment and to longer-dated U.S. Treasury note futures in a Not Rising interest rate environment. The Index will allocate to shorter-dated U.S. Treasury note futures in a Rising interest rate environment on the theory that shorter-dated notes may be less adversely affected by rising interest rates than longer-dated notes. The Index will allocate to longer-dated U.S. Treasury note futures in a Not Rising interest rate environment on the theory that longer-dated notes may provide a more favorable yield than shorter-dated notes when interest rates are not rising. These theories may or may not prove to be correct over any given period of time. The performance of each U.S. Treasury note futures index will be driven by market forces, which may not result in the relationship between shorter- and longer-dated U.S. Treasury notes described above. Even if these relationships do hold, the Index will determine the Treasury Futures Allocation based on the Rates Signal, which may fail to accurately capture the current interest rate environment because it is backward-looking.

Rates Signal

On each Index Business Day, the Index determines whether the United States is in a “Rising” or a “Not Rising” interest rate environment, which we refer to as the “Rates Signal”.

To make that determination on a given Index Business Day, the Index calculates the average daily rate of 3-month U.S. dollar LIBOR for each of four different periods, each consisting of 21 Index Business Days (approximately one month):

If the average rate of 3-month U.S. dollar LIBOR increased from each month to the next in that four-month period – in other words, if the average daily rate of 3-month U.S. dollar LIBOR is:

then the Rates Signal will determine on that Index Business Day that the United States is in a “Rising” interest rate environment. Put another way, the Rates Signal will identify a “Rising” interest rate environment if there have been three consecutive month-over-month increases in the average daily rate of 3-month U.S. dollar LIBOR. In any other circumstance, the Rates Signal will identify a “Not Rising” interest rate environment.

The examples below illustrate several different hypothetical determinations of the Rates Signal on a hypothetical Index Business Day. The examples are intended solely for illustrative purposes and are not an indication of what the average daily rate of 3-month U.S. dollar LIBOR or the Rates Signal may be at any given point in time.

Example 1: Rising

Example 2: Not Rising

Example 3: Not Rising

Example 4: Not Rising

As the examples illustrate, the Rates Signal will identify a “Rising” interest rate environment only if the average daily rate of 3-month U.S. dollar LIBOR has increased from each month to the next in the immediately preceding four months. As Example 2 shows, even if the average daily rate of 3-month U.S. dollar LIBOR generally rises over the four-month period but plateaus in the last month, the Rates Signal will identify a “Not Rising” interest rate environment. As Example 3 shows, even if the average daily rate of 3-month U.S. dollar LIBOR has sharply risen in the most recent months, the Rates Signal will not identify a “Rising” interest rate environment unless there have been three consecutive month-over-month increases.

Because of the way in which the Rates Signal is determined, the Index may fail to identify that interest rates are rising at a time when other measures would so indicate. As a result, the Index may implement its investment thesis less effectively than it would if it used an alternative method of calculating the Rates Signal.

On any Index Business Day, 3-month U.S. dollar LIBOR is the “ICE London – Interbank Offered Rate USD 3 Month” as published on Bloomberg page “US0003M” (or any success or substitute page) on that Index Business Day (or, if not published on that Index Business Day, as published on the first preceding Index Business Day).

In the event that the Index Administrator determines that 3-month U.S. dollar LIBOR has been discontinued or is permanently no longer published or is no longer widely relied upon by market participants as a benchmark interest rate (other than for legacy financial instruments linked to 3-month U.S. dollar LIBOR), the Index Administrator may select a substitute or successor rate that it has determined (after consulting any source that it deems reasonable) using Expert Judgment (as defined below) is (1) the industry-accepted substitute or successor rate or (2) if there is no such industry-accepted substitute or successor rate, a substitute or successor rate which is the most comparable to 3-month U.S. dollar LIBOR (as 3-month U.S. dollar LIBOR exists as of the launch date of the Index).

Upon selection of a substitute or successor rate, the Index Administrator may determine (after consulting any source that it deems reasonable) using Expert Judgment any adjustment factor it determines is needed to make such substitute or successor rate comparable to 3-month U.S. dollar LIBOR, in a manner which is consistent with any industry-standard practice for such substitute or successor rate.

Selection and Composition of the Selected Portfolio

As described above, the hypothetical investment portfolio tracked by the Index at any given time, which we refer to as the Selected Portfolio at that time, will be composed of up to three separate hypothetical allocations: an Equity Allocation, a Treasury Futures Allocation and a Cash Allocation. The equity sector ETFs that will make up the Equity Allocation and the U.S. Treasury note futures index that will make up the Treasury Futures Allocation will be determined on each Index Business Day based on the Rates Signal.

If the Rates Signal indicates a “Rising” interest rate environment, then the Equity Allocation will consist of the Energy Select Sector SPDR^® Fund, the Financial Select Sector SPDR^® Fund and the Technology Select Sector SPDR^® Fund, and the Treasury Futures Allocation will consist of the Citi Interest Rate 2Y US Treasury Futures Market Tracker Index.

If the Rates Signal indicates a “Not Rising” interest rate environment, then the Equity Allocation will consist of the Utilities Select Sector SPDR^® Fund, the Consumer Staples Select Sector SPDR^® Fund and the Health Care Select Sector SPDR^® Fund, and the Treasury Futures Allocation will consist of the Citi Interest Rate 10Y US Treasury Futures Market Tracker Index.

The equity sector ETFs that make up the Equity Allocation will be equally weighted with each other within the Equity Allocation. That equal weighting will be reset on each Index Business Day so that, from each Index Business Day to the next, one-third of the portion of the Index’s performance that results from the Equity Allocation will be attributable to each of the selected equity sector ETFs.

The Index determines how much exposure to allocate to each of the Equity Allocation, the Treasury Futures Allocation and the Cash Allocation on a daily basis in a manner designed to maintain a target volatility of the Index of 3.5%. This volatility-targeting feature is applied in two stages. First, the Index will allocate exposure between the Equity Allocation and the Treasury Futures Allocation within the Invested Allocation based on the volatility of the current Equity Allocation over the prior six months, with higher volatility resulting in a lower Equity Allocation, and vice versa. Second, the Index will allocate exposure between the Invested Allocation and the Cash Allocation based on the volatility of the Invested Allocation over the prior one month. In this second stage, the Index will, if necessary, reduce exposure to the Invested Allocation and increase exposure to the Cash Allocation (which has no volatility) in an attempt to maintain a rolling one-month Selected Portfolio volatility of 3.5%.

Stage 1

The Equity Allocation and the Treasury Futures Allocation together make up the overall Invested Allocation. Within the Invested Allocation, the Index determines how to allocate exposure between the Equity Allocation and the Treasury Futures Allocation on each Index Business Day in three steps:

For example, if the annualized volatility of the current Equity Allocation over the prior six months were 20%, then the portion of the Invested Allocation to allocate to the Equity Allocation would be determined by dividing 3.5% by 20%, which would result in a 17.5% allocation to the Equity Allocation within the Invested Allocation. The remaining 82.5% would be allocated to the Treasury Futures Allocation.

Stage 2

After completion of Stage 1, the Index determines how to allocate exposure within the Selected Portfolio between the Invested Allocation and the Cash Allocation in three steps:

For example, if the annualized volatility of the Invested Allocation over the prior month were 10%, then the portion of the Selected Portfolio to allocate to the Invested Allocation would be determined by dividing 3.5% by 10%, which would result in a 35% allocation to the Invested Allocation within the Selected Portfolio. The remaining 65% would be allocated to the Cash Allocation. If, on the other hand, the annualized volatility of the

Invested Allocation over the prior month were 3.5% or less, then the Selected Portfolio would allocate 100% of its exposure to the Invested Allocation and there would be no Cash Allocation.

Whereas the allocation in Stage 1 is based on what the volatility of the current Equity Allocation would have been over the preceding six months, the allocation in Stage 2 is based on the volatility of the actual Invested Allocation on each Index Business Day over the preceding month. The volatility of the actual Invested Allocation over the preceding month may differ from what the volatility of the current Invested Allocation would have been over the same time period, which may reduce the effectiveness of the Index’s volatility targeting feature.

Any change in the Rates Signal and/or the volatility of the current Equity Allocation from one Index Business Day to the next will result in a change in the composition of, and/or allocations within, the Invested Allocation at the end of the next Index Business Day after the Index Business Day on which the change occurs. Any change in the calculated allocation between the Invested Allocation and the Cash Allocation will be given effect at the close of the Index Business Day on which the change in calculation occurs.

No interest or other return will accrue on the portion of the Selected Portfolio that is allocated to the Cash Allocation. As a result, any allocation to the Cash Allocation will dampen Index returns. In general, the Cash Allocation is likely to be greatest at a time when the one-month volatility of the equity sector ETFs making up the actual Equity Allocation over the preceding month has increased significantly from the six-month volatility of the current Equity Allocation.

It is important to note that the Index relies on historical observations of volatility in an attempt to maintain its target volatility of 3.5%. As future volatility differs from this historical observed volatility, the actual level of volatility experienced by the Index may significantly exceed its target volatility, and the Index level may decline significantly as a result.

Excess Return Deduction

As described above, the performance of each U.S. Treasury note futures index is expected to generally reflect changes in the value of the underlying U.S. Treasury notes, as reduced by an implicit financing cost. In addition, for purposes of the Index, the performance of each equity sector ETF will be calculated on a daily basis after deducting a rate equal to the federal funds effective rate from its actual total return performance (giving effect to the hypothetical reinvestment of any dividends paid on the equity sector ETF). We refer to this deduction, together with the implicit financing cost in the performance of each U.S. Treasury note futures index, as the “excess return deduction”. The excess return deduction will cause the performance of each U.S. Treasury note futures index to be significantly less than the performance of the underlying U.S. Treasury notes, and will cause the performance of each equity sector ETF, as measured for purposes of the Index, to be significantly less than its actual performance. The excess return deduction means that the Selected Portfolio will not have positive returns unless the relevant U.S. Treasury notes and/or equity sector ETFs appreciate sufficiently to offset the excess return deduction. Because of the excess return deduction, the Selected Portfolio (and, in turn, the Index) may have negative returns even if the relevant U.S. Treasury notes and/or equity sector ETFs appreciate.

The federal funds effective rate on each Index Business Day will be the rate published on Bloomberg page “FEDL01<Index>” (or any successor or substitute page) on the immediately preceding Index Business Day (or, if not published on such day, as published on the first preceding Index Business Day). The federal funds effective rate is the weighted average across all transactions of the interest rate at which depository institutions (such as banks and credit unions) lend reserve balances to each other overnight on an uncollateralized basis.

If market interest rates, including the federal funds effective rate, rise for any reason, the negative impact of the excess return deduction will increase, and the performance of the Selected Portfolio (and, in turn, the Index) will be adversely affected.

The excess return deduction will place a drag on the performance of the Index, offsetting any appreciation of the U.S. Treasury notes underlying the applicable U.S. Treasury note futures index and the equity sector ETFs that

make up the Equity Allocation, exacerbating any depreciation and causing the value of the Selected Portfolio to decline steadily if the value of those U.S. Treasury notes and/or equity sector ETFs remains relatively constant.

Index Fee

An index fee is deducted in the calculation of the Index at a rate of 0.75% per annum.

Index Level Calculation

The level of the Index (the “Index Level”) is calculated by the Index Calculation Agent on each Index Business Day, subject to the occurrence of a Disrupted Day as described under “—Adjustments, Disruption and Cancellation” below. The Index Level is published on Bloomberg page “CIISRA35<Index>,” generally on the following Index Business Day. The Index Level as of any Index Business Day is the closing level of the Index for that Index Business Day. The Index launched on August 25, 2020 and was set to a starting Index Level of 100 on the “Index Start Date” of January 2, 2003.

The Index Level is calculated on each Index Business Day based on (i) the closing price of each applicable equity sector ETF as published on the Bloomberg page “[Ticker] UP Equity” (or any successor or substitute page), where “[Ticker]” refers to the ticker symbol of the applicable equity sector ETF and (ii) the official closing level of the applicable U.S. Treasury note futures index, as published by Citigroup Global Markets Limited (in its capacity as Index Administrator of the U.S. Treasury note futures indices).

“Index Business Day” means each day (1) on which commercial banks and foreign exchange markets are scheduled to be open for general business (including dealings in foreign exchange and foreign exchange currency deposits) in New York City and (2) which is also a Scheduled Trading Day for each of the Constituents.

A “Scheduled Trading Day” means (i) with respect to any equity sector ETF, any day on which the relevant Exchange and each relevant Related Exchange are scheduled to be open for trading for their respective regular trading sessions or (ii) with respect to any U.S. Treasury note futures index, any day on which Citigroup Global Markets Limited (or an agent appointed by Citigroup Global Markets Limited) is scheduled to publish the level of the relevant U.S. Treasury note futures index.

“Constituent” means an equity sector ETF or a U.S. Treasury note futures index that is eligible to be included in the Selected Portfolio.

“Regulatory Action” means, in respect of any relevant equity sector ETF, (1) the cancellation, suspension or revocation of the registration or approval of such equity sector ETF by any relevant governmental, legal or regulatory authority; (2) any change in the accounting, legal, regulatory or tax treatments of such equity sector ETF or its Fund Adviser that is reasonably likely to have an adverse impact on the value of such equity sector ETF or on any investor therein; or (3) equity sector ETF or any of its Fund Administrator or Fund Adviser becoming subject to any investigation, proceeding or litigation by any relevant governmental, legal or regulatory authority involving the alleged violation of applicable law for activities relating to or resulting from the operation of such equity sector ETF, Fund Administrator or Fund Adviser.

“Reporting Disruption” means, in respect of any relevant equity sector ETF, (1) the occurrence of any event affecting such equity sector ETF which would make it impossible or impracticable for the Index Calculation Agent to determine the value of such equity sector ETF for the foreseeable future; (2) any failure of such equity sector ETF to deliver, or cause to be delivered, (a) information that such equity sector ETF has agreed to deliver or cause to be delivered; or (b) information that has been previously delivered in accordance with the normal practice of such equity sector ETF or its authorized representative, which enable such equity sector ETF’s compliance with any investment guideline, asset allocation methodology or other similar policy to be monitored.

“Strategy Breach” means, in respect of any relevant equity sector ETF, any breach or violation of any strategy or investment guideline stated in the Fund Documents of such equity sector ETF which could reasonably be expected to affect the value of such equity sector ETF or the rights and remedies of holders of such equity sector ETF from those prevailing on the Index Start Date.

“Constituent Index Cancellation” means, in respect of any relevant U.S. Treasury note futures index, that Citigroup Global Markets Limited permanently cancels such index.

“Constituent Index Modification” means, in respect of any relevant U.S. Treasury note futures index, that Citigroup Global Markets Limited announces that it will make a material change in the formula for or method of calculating such U.S. Treasury note futures index or in any other way materially modifies such U.S. Treasury note futures index (other than a modification prescribed in that formula or method to maintain such U.S. Treasury note futures index in the event of routine events).

Postponement of Rebalancing

If any Index Business Day is not a Scheduled Trading Day for any Constituent, then any change in the composition of, and allocations within, the Invested Allocation (such change, a “rebalancing”) otherwise scheduled to take place on that Index Business Day will instead take place on the first succeeding Index Business Day that is a Scheduled Trading Day for all Constituents. If any Index Business Day is a Disrupted Day for any Constituent, any rebalancing scheduled to occur on such Index Business Day will take place (i) for any Constituent for which such Index Business Day is not a Disrupted Day, on such Index Business Day and (ii) for any Constituent for which such Index Business Day is a Disrupted Day, on the earlier of (a) the first succeeding Index Business Day that is both a Scheduled Trading Day for such Constituent and not a Disrupted Day for such Constituent and (b) the fifth Scheduled Trading Day for such Constituent immediately following such Index Business Day.

In addition, if any Index Business Day is a Disrupted Day for any Constituent, then the Index Calculation Agent may:

“Disrupted Day” means (i) in the case of any relevant equity sector ETF, any Scheduled Trading Day on which an Exchange Disruption occurs in respect of such equity sector ETF or (ii) in respect of any relevant U.S. Treasury note futures index, any Scheduled Trading Day on which the level of such U.S. Treasury note futures index is not published by or on behalf of Citigroup Global Markets Limited.

In the case of any relevant equity sector ETF, “Exchange Disruption” means:

“Related Exchange” means, in respect of any relevant equity sector ETF, each Trading Venue in respect of any futures contract or option contract (“Securities Derivatives”) relating to such equity sector ETF, or any successor to such Trading Venue, or any substitute Trading Venue to which trading in the relevant Securities Derivatives has temporarily relocated, provided that, in the determination of the Index Calculation Agent, there is comparable liquidity in the relevant Securities Derivatives on such temporary substitute Trading Venue as on the original Trading Venue.

“Valuation Time” means the Scheduled Closing Time on the relevant Exchange.

“Scheduled Closing Time” means, in respect of a Scheduled Trading Day and an Exchange or Related Exchange (as relevant), the scheduled weekday closing time on such Exchange or Related Exchange (as relevant) on such Scheduled Trading Day, without regard to after-hours trading or any other trading outside the hours of the regular trading session on such Exchange or Related Exchange.

“Exchange Business Day” means any Scheduled Trading Day for any relevant equity sector ETF on which each relevant Exchange and each relevant Related Exchange is open for trading during its respective regular trading session, notwithstanding any such Exchange or any such Related Exchange closing prior to its Scheduled Closing Time.

Successor Constituent Index

If a U.S. Treasury note futures index is (1) not calculated and announced by Citigroup Global Markets Limited but is calculated and announced by a successor sponsor acceptable to the Index Calculation Agent or (2) replaced by a successor index using, in the determination of the Index Calculation Agent, the same or a substantially similar formula for or method of calculation as used in the calculation of such index, then in each case that index will be deemed to be the relevant U.S. Treasury note futures index with effect from the date determined by the Index Calculation Agent, who may (but is not obliged to) make such adjustment(s) to the Index Rules as it determines appropriate to account for such change.

Corrections

If the price or level of any Constituent for any time on any day that is (1) announced by or on behalf of the person or entity responsible for such publication or announcement and (2) used for any calculation or determination in respect of the Index, is subsequently corrected, and the corrected price or level (the “Corrected Level”) is published by or on behalf of such person or entity within the Correction Period in respect of such Constituent, then such Corrected Level shall be deemed to be the price or level for such Constituent for the relevant time on the relevant day. In such event, the Index Calculation Agent may, but will not be obliged to, make appropriate adjustments to the Index Level for such day (using Expert Judgment), and the Index Calculation Agent will exercise such Expert Judgment in a manner that is consistent with the primary objective of the Index.

The “Correction Period” is (i) two Index Business Days in the case of an equity sector ETF and (ii) 30 calendar days in the case of the U.S. Treasury note futures indices.

Ambiguities, errors and omissions

It is possible that ambiguities, errors and omissions may arise in certain circumstances. The Index Administrator will resolve, using Expert Judgement, any such ambiguity, error or omission, and may amend the Index Rules to reflect the resolution of such ambiguity, error or omission.

Cancellation of the Index

The Index Administrator may discontinue and cancel the Index at any time and is under no obligation to continue, or to procure the continuation of, the calculation, publication and dissemination of the Index and the Index Level.

Regulatory Event

Following the occurrence of a Regulatory Event, the Index Calculation Agent will determine whether or not such occurrence has a material effect on the Index.

(1)       If the Index Calculation Agent determines that such occurrence has a material effect on the Index, then the Index Calculation Agent will inform the Index Administrator of such determination and either:

(a) the Index Administrator will follow procedures established by the Index Governance Committee in order to amend the Index Rules; or

(b) the Index Administrator may discontinue and cancel the Index.

(2)       If the Index Calculation Agent determines that such occurrence does not have a material effect on the Index, then with effect from (and including) a date designated by the Index Administrator (in which case the Index Administrator will notify the relevant date to the Index Calculation Agent) or the Index Calculation Agent:

(a) the Constituent affected by such Regulatory Event (the “Removed Constituent”) will be removed from the Index; and

(b)       subject to the Index methodology and the Expert Judgment of the Index Calculation Agent, either (i) the weight of the remaining Constituents will be scaled up such that the weight of the Removed Constituent is proportionately redistributed to the remaining Constituents or (ii) the Index Calculation Agent may replace the Removed Constituent with a replacement constituent which has substantially similar characteristics to the Removed Constituent, having regard to the manner in which the Removed Constituent is used in the calculation of the Index, in which case the Index Calculation Agent will determine the effective date of such replacement and make such adjustment(s) to the Index Rules as it determines appropriate to account for the effect on the Index of such replacement.

A “Regulatory Event” means that, owing to any change in applicable law or regulation, the Index Calculation Agent determines that either:

(1)       a hypothetical broker dealer (subject to a regulatory regime comparable to the regime applicable to U.S.-registered broker-dealers) would be either (a) required (or there is a reasonable likelihood that, within the next 30 Index Business Days, it would be required) to unwind positions in, or dispose of, any instrument or security on which the value of a Constituent depends or (b) not permitted (or there is a reasonable likelihood that, within the next 30 Index Business Days, it would not be permitted) to hold, acquire, establish, increase, decrease or dispose of positions in any instrument or security on which the value of a Constituent depends; or

(2)       the Index Administrator or the Index Calculation Agent is not permitted (or there is a reasonable likelihood that, within the next 30 Index Business Days, it will not be permitted) to continue to sponsor, administer, maintain or calculate, as applicable, an index which contains a particular instrument or security on which the value of a Constituent depends.

Expert Judgment

Each of the Index Administrator and the Index Calculation Agent, as relevant, is obligated to exercise any discretion and make any determination in respect of the Index by using a standard of judgement (“Expert Judgment”) consisting of (1) acting in good faith and in a commercially reasonable manner; (2) to the extent practicable, reflecting the commercial objective of the Index and market practice; and (3) to the extent practicable, promoting consistency in the exercise of discretions and the making of determinations in respect of both the Index and other indices in respect of which it acts, as relevant, as index administrator or index calculation agent.

In using Expert Judgment to exercise any discretion or to make any determination, the Index Administrator will be subject to the oversight of the Index Governance Committee, whose role is described below. In using Expert Judgment to exercise any discretion or to make any determination, the Index Calculation Agent will be subject to the oversight of the Index Administrator. The Index Governance Committee will review any such use of Expert Judgment in extraordinary circumstances.

Index Governance

The Index Administrator has ultimate control over the development, the operation and the publication of the Index, including the performance of any calculation, the exercise of any discretion, the making of any determination, and all administrative processes required to perform these functions (together, the “Index Activity”). Notwithstanding that certain parts of the Index Activity may be performed by persons other than the Index Administrator, the Index Administrator has overall responsibility for all parts of the Index Activity.

The Index Administrator maintains oversight over the Index Activity through its Index Governance Committee. The Index Governance Committee fulfils its role of ensuring accountability and providing oversight through (1) reviewing and challenging all parts of the Index Activity, in accordance with its charter and its written policies and procedures; and (2) conducting an annual review of the Index to determine whether it continues to be an accurate and reliable representation of the economic realities of the relevant interest or market.

Hypothetical Back-Tested Index Performance Information

Hypothetical back-tested performance information for the Index may be provided in connection with the offering of any investment linked to the Index. All Index performance information prior to August 25, 2020 is hypothetical and back-tested, as the Index did not exist prior to that date. Hypothetical back-tested Index performance information is subject to significant limitations. The Index Administrator developed the Index Rules with the benefit of hindsight—that is, with the benefit of being able to evaluate how the Index Rules would have caused the Index to perform had it existed during the hypothetical back-tested period. The fact that the Index generally appreciated over the hypothetical back-tested period may not therefore be an accurate or reliable indication of any fundamental aspect of the Index methodology. Furthermore, the hypothetical back-tested performance of the Index might look different if it covered a different historical period. The market conditions that existed during the hypothetical back-tested period may not be representative of market conditions that will exist in the future.

The hypothetical back-tested Index information has been calculated by the Index Administrator. The hypothetical back-tested Index levels have been calculated by the Index Administrator by applying the Index methodology substantially as described above to the actual published closing prices of the equity sector ETFs and published values of 3-month U.S. dollar LIBOR during the back-tested period. The U.S. Treasury note futures indices were first published on April 28, 2017. Accordingly, for purposes of preparing hypothetical back-tested Index information, the Index Administrator used the actual published levels of the U.S. Treasury note futures indices for all periods since April 28, 2017, and hypothetical back-tested levels of the U.S. Treasury note futures indices for all periods prior to that date. The hypothetical back-tested levels of the U.S. Treasury note futures indices have been calculated by Citigroup Global Markets Limited (in its capacity as Index Administrator of the U.S. Treasury note futures indices) by applying the methodology substantially as described under “Description of the U.S. Treasury Note Futures Indices” to the actual published settlement prices of the underlying U.S. Treasury note futures contracts during the back-tested period.

Two of the equity sector ETFs have been affected by significant changes in the way the sectors they track are defined. Hypothetical back-tested performance information for the Index has been calculated based on the actual historical closing prices of all equity sector ETFs. For all periods prior to the changes described below, the closing prices for the two affected equity sector ETFs are likely to have been different than they would have been had these equity sector ETFs tracked their target sectors as currently defined.

As a result of the above, the hypothetical back-tested Index performance information may not reflect how the Index would have performed if the two equity sector ETFs had tracked their target sectors as currently defined.

It is impossible to predict whether the Index will rise or fall. By providing hypothetical back-tested and historical Index performance information in connection with the Notes, we are not representing that the Index is likely to achieve gains or losses similar to those shown. In fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular investment. One of the limitations of hypothetical performance information is that it did not involve financial risk and cannot account for all factors that would affect actual performance. The actual future performance of the Index may bear no relation to the hypothetical or historical back-tested performance of the Index.

INFORMATION ABOUT THE EQUITY SECTOR ETFS

The equity sector ETFs that are eligible for inclusion in the Index are exchange-traded funds sponsored by State Street Global Advisors and traded on the NYSE Arca. Each equity sector ETF seeks to provide investment results that, before expenses, correspond generally to the price and yield performance of one of the Select Sector Indices published by S&P Dow Jones Indices (“S&P”). Each Select Sector Index represents one sector within the S&P 500^® Index, which is divided into a total of 11 sectors. The S&P 500^® Index consists of stocks of 500 companies selected to provide a performance benchmark for the large capitalization segment of the U.S. equity market.

Each equity sector ETF is a separate series of the Select Sector SPDR Trust (the “Trust”), which is an open-end registered management investment company. Information provided to or filed with the SEC by the Trust pursuant to the Securities Act of 1933, as amended, and the Investment Company Act of 1940, as amended, can be located by reference to SEC file numbers 333-57791 and 811-08837, respectively, through the SEC’s website at http://www.sec.gov. In addition, information may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents.

We have derived all information regarding the equity sector ETFs from publicly available information and have not independently verified that information.

The table below lists the equity sector ETFs that are eligible for inclusion in the Index and indicates, for each equity sector ETF, its ticker symbol and the Select Sector Index that it seeks to track.

Select Sector Indices

Each Select Sector Index represents one sector within the S&P 500^® Index. The S&P 500^® Index is divided into 11 sectors in accordance with the Global Industry Classification Standard (“GICS”).

The table below indicates, for each Select Sector Index tracked by an equity sector ETF that is eligible for inclusion in the Index, the GICS sector that corresponds to that Select Sector Index. For information about GICS sectors, see “—GICS” below.

The Select Sector Indices are calculated, maintained and governed using the same methodology as the S&P 500^® Index, subject to a capping methodology. Components are weighted by their float-adjusted market-capitalization, subject to a cap as of each quarterly rebalance. The Select Sector Indices are rebalanced quarterly after the close of business on the third Friday of March, June, September, and December using the following procedures:

1. The rebalancing reference date is the second Friday of March, June, September and December.

2. With prices reflected on the rebalancing reference date, and membership, shares outstanding and investable weight factors as of the rebalancing effective date, each company is weighted by float-adjusted market capitalization, subject to the modifications described below.

3. If any company has a weight greater than 24%, the company’s float-adjusted market capitalization weight is capped at 23%, which allows for a 2% buffer. This buffer is meant to ensure that no company exceeds 25% as of the quarter-end diversification requirement date.

4. All excess weight is proportionally redistributed to all uncapped companies within the relevant Select Sector Index.

5. After this redistribution, if the float-adjusted market capitalization weight of any other company then breaches 23%, the process is repeated iteratively until no company breaches the 23% weight cap.

6. The sum of the companies with weights greater than 4.8% cannot exceed 50% of the total index weight. These caps are set to allow for a buffer below the 5% limit.

7. If the rule in paragraph 6 is breached, all companies are ranked in descending order of their float-adjusted market capitalization weights. The first company that causes the 50% limit to be breached has its weight reduced to 4.5%.

8. This excess weight is proportionally redistributed to all companies with weights below 4.5%. This is repeated iteratively until paragraph 6 is satisfied.

9. Index share amounts are assigned to each constituent to arrive at the weights calculated above. Since index shares are assigned based on prices one week prior to rebalancing, the actual weight of each constituent at the rebalancing differs somewhat from these weights due to market movements

10. If necessary, the reweighting process may take place more than once prior to the close on the last business day of March, June, September or December to ensure the Select Sector Indices conform to all diversification requirements.

If necessary, the reweighting process may take place more than once prior to the close on the last business day of March, June, September or December to ensure the Select Sector Indices conform to all diversification requirements.

When companies represented in the Select Sector Indices are represented by multiple share classes, maximum weight capping is based on company float-adjusted market capitalization, with the weight of multiple-class companies allocated proportionally to each share class based on its float-adjusted market capitalization as of the rebalancing reference date. If no capping is required, both share classes remain in the relevant Select Sector Index at their natural float-adjusted market capitalization.

All information regarding the Select Sector Indices has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, S&P.

GICS

GICS was developed in 1999 by S&P and MSCI as a framework for classifying companies within sectors, industry groups, industries and sub-industries. The “sector” is the highest and most general level of classification within GICS.

GICS classifies a company according to its principal business activity. To make this determination, S&P and MSCI use revenues as the key measure identifying a company’s principal business activity. However, earnings and market perception are also taken into account during the review process.

The following table lists the 11 GICS sectors and the industries that make up each sector.

Companies’ GICS classifications are reviewed at least annually, and are also under constant surveillance for corporate actions potentially impacting classification. In general, a GICS code changes whenever there is a major corporate action that redefines a company's primary business activity. At a minimum, annual reviews are conducted to ensure that a company has not redefined its primary business activity through a series of smaller events. S&P and MSCI review the GICS structure on an annual basis.

All information regarding the GICS has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, S&P and MSCI.

S&P 500^® Index

The S&P 500^® Index consists of stocks of 500 companies selected to provide a performance benchmark for the large capitalization segment of the U.S. equity market. All information regarding the S&P 500^® Index has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, S&P.

Composition of the S&P 500^® Index

Securities must satisfy the following eligibility factors to be considered for inclusion in the S&P 500^® Index. Constituent selection is at the discretion of S&P’s U.S. index committee (for purposes of this section, the “Index Committee”) and is based on the eligibility criteria.

Changes to the S&P 500^® Index are made as needed, with no scheduled reconstitution. Rather, changes in response to corporate actions and market developments can be made at any time. Constituent changes are typically announced one to five days before they are scheduled to be implemented.

Additions to the S&P 500^® Index are evaluated based on the following eligibility criteria:

plurality when there is incomplete asset information. If this criteria is not met or is ambiguous, S&P may still deem the company to be a U.S. company for index purposes if its primary listing, headquarters and incorporation are all in the United States and/or “a domicile of convenience” (Bermuda, Channel Islands, Gibraltar, islands in the Caribbean, Isle of Man, Luxembourg, Liberia or Panama); and

In situations where the only factor suggesting that a company is not a U.S. company is its tax registration in a “domicile of convenience” or another location chosen for tax-related reasons, S&P normally determines that the company is still a U.S. company. The final determination of domicile eligibility is made by the Index Committee, which can consider other factors including, but not limited to, operational headquarters location, ownership information, location of officers, directors and employees, investor perception and other factors deemed to be relevant.

As of July 31, 2017, companies with multiple share class structures are not eligible to be added to the S&P 500^® Index, but securities already included in the S&P 500^® Index have been grandfathered and will remain in the S&P 500^® Index.

Exceptions to the above criteria include:

S&P believes turnover in membership in the S&P 500^® Index should be avoided when possible. At times a stock may appear to temporarily violate one or more of the addition criteria. However, the addition criteria are for addition to the S&P 500^® Index, not for continued membership. As a result, a constituent of the S&P 500^® Index that appears to violate criteria for addition to the S&P 500^® Index is not deleted unless ongoing conditions warrant an index change.

Removals from the S&P 500^® Index are evaluated based as follows:

Any company that is removed from the S&P 500^® Index (including discretionary and bankruptcy/exchange delistings) must wait a minimum of one year from its index removal date before being reconsidered as a replacement candidate.

Calculation of the S&P 500^® Index

The S&P 500^® Index is a float-adjusted market capitalization-weighted index. On any given day, the index value of each S&P U.S. Index is the total float-adjusted market capitalization of that S&P U.S. Index’s constituents divided by its divisor. The float-adjusted market capitalization reflects the price of each stock in the relevant S&P U.S. Index multiplied by the number of shares used in the index value calculation.

Float Adjustment. Float adjustment means that the number of shares outstanding is reduced to exclude closely held shares from the calculation of the index value because such shares are not available to investors. The goal of float adjustment is to distinguish between strategic (control) shareholders, whose holdings depend on concerns such

as maintaining control rather than the economic fortunes of the company, and those holders whose investments depend on the stock’s price and their evaluation of a company’s future prospects. Generally, these “control holders” include officers and directors, private equity, venture capital & special equity firms, other publicly traded companies that hold shares for control, strategic partners, holders of restricted shares, employee stock ownership plans, employee and family trusts, foundations associated with the company, holders of unlisted share classes of stock or government entities at all levels (other than government retirement/pension funds) and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. Shares that are not considered outstanding are also not included in the available float. These generally include treasury stock, stock options, equity participation units, warrants, preferred stock, convertible stock and rights.

For each component, S&P calculates an (“IWF”), which represents the portion of the total shares outstanding that are considered part of the public float for purposes of the relevant S&P U.S. Index.

Divisor. Continuity in index values of each S&P 500^® Index is maintained by adjusting its divisor for all changes in its constituents’ share capital after its base date. This includes additions and deletions to the relevant S&P U.S. Index, rights issues, share buybacks and issuances and non-zero price spin-offs. The value of each S&P U.S. Index’s divisor over time is, in effect, a chronological summary of all changes affecting the base capital of that S&P U.S. Index. The divisor of each S&P U.S. Index is adjusted such that the index value of that S&P U.S. Index at an instant just prior to a change in base capital equals the index value of that S&P U.S. Index at an instant immediately following that change.

Maintenance 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 one to five days before they are scheduled to be implemented.

Share Updates. All mergers and acquisitions (“M&A”) driven changes to the S&P 500^® Index are implemented with one to five business days’ notice on a best efforts basis. Any share issuance for the acquirer is implemented to coincide with the drop event for the target. An M&A driven share/IWF change does not need to meet any minimum threshold requirement for implementation. This helps minimize turnover in indices. Any merger related IWF change that results in an IWF of 0.96 or greater is rounded up to 1.00 at the next annual IWF review. At S&P’s discretion, de minimis merger and acquisition share changes are accumulated and implemented with the quarterly share rebalancing. All other changes of less than 5% are accumulated and made quarterly on the third Friday of March, June, September and December.

5% Rule. Confirmed share changes that are at least 5% of the total shares outstanding are implemented weekly. Total shares outstanding and not float-adjusted shares are used to determine whether the share change meets this 5% threshold. The 5% rule applies to share changes only. IWF changes are only considered if a share change meets the 5% threshold.

Changes to an index constituent’s total shares outstanding of at least 5% are applied weekly and are announced after the market close on Fridays for implementation after the close of trading the following Friday (i.e., one week later). Examples of such changes include public offerings (also known as secondary offerings or follow-on offerings), tender offers, Dutch auctions, exchange offers, bought deal equity offerings, prospectus offerings, company stock repurchases, private placements, redemptions, exercise of options, warrants, conversion of derivative securities, at-the-market stock offerings, and acquisitions of private companies or non-index companies that do not trade on a major exchange. If an exchange holiday/closure falls on a Friday, the weekly share change announcement will be made the day before the exchange holiday/closure, and the implementation date will remain after the close of trading the following Friday (i.e., one week later).

If a 5% or more share change causes a company’s IWF to change by five percentage points or more (for example from 0.80 to 0.85), the IWF is updated at the same time as the share change. IWF changes resulting from partial tender offers are considered on a case by case basis.

Notwithstanding the foregoing, share or IWF changes of 5% or more due to public offerings (also known as placements or secondary offerings) are made effective at the open of the next day under certain conditions.

Secondary offerings by selling shareholders are recognized the next day if certain conditions are met, or weekly via an IWF change if the secondary offering is at least 5% of total shares outstanding.

Share/IWF Freezes. A share/IWF freeze period is implemented during each quarterly rebalancing. The freeze period begins after the market close on the Tuesday preceding the second Friday of each rebalancing month (i.e., March, June, September, and December) and ends after the market close on the third Friday of a rebalancing month. Pro-forma files are normally released after the market close on the second Friday, one week prior to the rebalancing effective date. In September, preliminary share and float data are released on the first Friday of the month, but the share freeze period for September will follow the same schedule as the other three quarterly share freeze periods. For illustration purposes, if rebalancing pro-forma files are scheduled to be released on Friday, March 13, the share/IWF freeze period will begin after the close of trading on Tuesday, March 10 and will end after the close of trading the following Friday, March 20 (i.e., the third Friday of the rebalancing month).

During the share/IWF freeze period, shares and IWFs are not changed except for certain corporate action events (such as merger activity, stock splits, rights offerings). Share/IWF changes for index constituents resulting from secondary public offerings that would otherwise be eligible for next day implementation are instead collected during the freeze period and added to the weekly share change announcement on the third Friday of the rebalancing month for implementation the following Friday night. There is no weekly share change announcement on the second Friday of a rebalancing month.

Corporate Actions. Corporate actions (such as stock splits, stock dividends, non-zero price spin-offs and rights offerings) are applied after the close of trading on the day prior to the ex-date.

Other Adjustments. In cases where there is no achievable market price for a stock being deleted, it can be removed at a zero or minimal price at the Index Committee’s discretion.

The table below summarizes the types of index maintenance adjustments and indicates whether or not a divisor adjustment is required.

Stock splits and stock dividends do not affect the divisor, because following a split or dividend, both the stock price and number of shares outstanding are adjusted by S&P so that there is no change in the market value of the

relevant component. All stock split and dividend adjustments are made after the close of trading on the day before the ex-date.

Governance of the S&P 500^® Index

The S&P 500^® Index is maintained by the Index Committee. All Index Committee members are full-time professional members of S&P’s staff. The Index Committee meets monthly. At each meeting, the Index Committee reviews pending corporate actions that may affect index constituents, statistics comparing the composition of the S&P 500^® Index to the market, companies that are being considered as candidates for addition to the S&P 500^® Index, and any significant market events. In addition, the Index Committee may revise index policy covering rules for selecting companies, treatment of dividends, share counts or other matters.

The Index Committee reserves the right to make exceptions when applying the methodology if the need arises. In any scenario where the treatment differs from the general rules stated in this document or supplemental documents, clients will receive sufficient notice, whenever possible.

In addition to its daily governance of the S&P 500^® Index and maintenance of index methodologies, at least once within any 12-month period, the Index Committee reviews this methodology to ensure the S&P 500^® Index continue to achieve the stated objectives, and that the data and methodology remain effective. In certain instances, S&P may publish a consultation inviting comments from external parties.

The Index Committee may change the date of a given rebalancing for reasons including market holidays occurring on or around the scheduled rebalancing date.

DESCRIPTION OF THE U.S. TREASURY NOTE FUTURES INDICES

Overview

Citigroup Global Markets Limited is the index administrator and calculation agent of the two U.S. Treasury note futures indices that are eligible to be included in the Index:

Each U.S. Treasury note futures index tracks the performance of a hypothetical investment, rolled quarterly, in a near-maturity U.S. Treasury note futures contract. A U.S. Treasury note futures contract is a contract for the purchase of U.S. Treasury notes with maturities falling within a specified range on a fixed date in the future. The table below lists, for each U.S. Treasury note futures index, the futures contract tracked by that index and the U.S. Treasury notes that are eligible to be delivered upon settlement of that futures contract.

The futures contracts underlying the U.S. Treasury note futures indices have expiration dates in March, June, September, and December of each year. Each U.S. Treasury note futures index tracks the nearest-maturity futures contract specified in the table above, and then, as the expiration date of that futures contract approaches, will “roll” out of the expiring contract and into the futures contract with the next succeeding expiration date. By continually rolling out of an expiring contract and into another futures contract with a later expiration date, each U.S. Treasury note futures index maintains continuous exposure to a U.S. treasury note futures contract.

The value of a U.S. Treasury note futures contract will fluctuate with changes in the market value of its underlying U.S. Treasury notes. In general, the value of a U.S. Treasury note will fall as market interest rates rise, and rise as market interest rates fall. However, the value of a U.S. Treasury note futures contract will also fluctuate based on factors that are unique to a futures contract, such as supply and demand in the futures market, the time remaining to the maturity of the futures contract and market interest rates over the term of the contract. As discussed in more detail under “—Futures Contracts Generally” below, these factors are likely to cause a position in a U.S. Treasury note futures contract to reflect an implicit financing cost, which will lower the return on the futures contract as compared to a direct investment in the underlying U.S. Treasury notes. Accordingly, we expect the performance of each U.S. Treasury note futures index to generally reflect changes in the value of its underlying U.S. Treasury notes, as reduced by an implicit financing cost. We expect the implicit financing cost to rise if market interest rates rise.

Each U.S. Treasury note futures index tracks a hypothetical investment in its underlying futures contract. There is no actual futures contract to which any investor is entitled or in which any investor has any ownership or other interest. Each U.S. Treasury note futures index is merely a mathematical calculation that is performed by reference to a hypothetical position in its underlying futures contract.

The specific rules governing the calculation of the U.S. Treasury note futures indices are attached as Annex B to this Index Supplement. This description of the U.S. Treasury note futures indices is only a summary of those rules. You should understand that this summary does not describe the mathematical terms used in calculating the U.S. Treasury note futures indices, and as a result is more general than the precise mathematical formulations used to

calculate the U.S. Treasury note futures indices. The U.S. Treasury note futures indices will be governed by and calculated in accordance with the mathematical and other terms set forth in Annex B to this Index Supplement, and not this summary. If this description of the U.S. Treasury note futures indices conflicts with the rules described in Annex B, the rules described in Annex B control.

The 2Y U.S. Treasury note futures index is reported by Bloomberg under the ticker symbol “CIIRBF2U.” The 10Y U.S. Treasury note futures index is reported by Bloomberg under the ticker symbol “CIIRBF1U”.

The U.S. Treasury note futures indices launched on April 28, 2017 and, therefore, have a limited performance history.

Futures Contracts Generally

A futures contract is an agreement to buy or sell an underlying asset on a future expiration date at a price that is agreed upon today. If the underlying asset is worth more on the expiration date than the price specified in the futures contract, then the purchaser of that contract will achieve a gain on that contract, and if it is worth less, the purchaser will incur a loss.

For example, suppose that a futures contract entered into in January calls for the purchaser to buy the underlying asset in March at a price of $1,000. If the underlying asset is worth $1,200 in March, then upon settlement of the futures contract in March the purchaser will buy for $1,000 an underlying asset worth $1,200, achieving a $200 gain. Conversely, if the underlying asset is worth $800 in March, then upon settlement of the futures contract in March the purchaser will buy for $1,000 an underlying asset worth only $800, incurring a $200 loss.

The gain or loss to the purchaser of this futures contract is different from the gain or loss that could have been achieved by the direct purchase of the underlying asset in January and the sale of that underlying asset in March. This is because a futures contract is a “leveraged” way to invest in the underlying asset. In other words, purchasing a futures contract is similar to borrowing money to buy the underlying asset, in that (i) it enables an investor to gain exposure to the underlying asset without having to pay the full cost of it up front and (ii) it entails a financing cost.

This financing cost is implicit in the difference between the spot price of the underlying asset and the futures price. A “futures price” is the price at which market participants may agree today to buy or sell the underlying asset in the future, and the “spot price” is the current price of the underlying asset for immediate delivery. The futures price is determined by market supply and demand and is independent of the spot price, but it is nevertheless generally expected that the futures price will be related to the spot price in a way that reflects a financing cost (because if it did not do so there would be an opportunity for traders to make sure profits, known as “arbitrage”). For example, if January’s futures price is $1,000, January’s spot price may be $975. If the underlying asset is worth $1,200 in March, the gain on the futures contract would be $200 ($1,200 minus $1,000), while the gain on a direct investment made at the January spot price would have been $225 ($1,200 minus $975). The lower return on the futures contract as compared to the direct investment reflects this implicit financing cost. Because of this financing cost, it is possible for a purchaser to incur a loss on a futures contract even if the spot price of the underlying asset increases over the term of the futures contract. The amount of this financing cost is expected to increase as general market interest rates increase.

Futures contracts are standardized instruments that are traded on an exchange. On each trading day, the exchange determines a settlement price (which may also be referred to as a closing price) for that futures contract based on the futures prices at which market participants entered into that futures contract on that day. Open positions in futures contracts are “marked to market” and margin is required to be posted on each trading day. This means that, on each trading day, the current settlement price for a futures contract is compared to the futures price at which the purchaser entered into that futures contract. If the current settlement price has decreased from the initial futures price, then the purchaser will be required to deposit the decrease in value of that futures contract into an account. Conversely, if the current settlement price has increased, the purchaser will receive that cash value in its account. Accordingly, gains or losses on a futures contract are effectively realized on a daily basis up until the point when the position in that futures contract is closed out.

Because futures contracts have expiration dates, one futures contract must be rolled into another if there is a desire to maintain a continuous position in futures contracts on (rather than take delivery of) a particular underlying asset. This is typically achieved by closing out the position in the existing futures contract as its expiration date approaches and simultaneously entering into a new futures contract (at a new futures price based on the futures price then prevailing) with a later expiration date.

The performance of each U.S. Treasury note futures index is intended to reflect the daily gains or losses that would be realized on a hypothetical position, rolled quarterly, in its underlying futures contract. As described above, those gains or losses will correspond to daily fluctuations in the settlement price of the underlying futures contract.

Rolling the U.S. Treasury Note Futures Indices

Each U.S. Treasury note futures index aims to reflect the performance of a hypothetical rolling long position (i.e., a hypothetical position that has been bought) in a succession of futures contracts. Each U.S. Treasury note futures index includes provisions for the replacement of the then-current futures contract underlying that index as that contract approaches expiration (also referred to as “rolling”). This replacement occurs over a 3-day rolling period every quarter.

We refer to the futures contract to which each U.S. Treasury note futures index is exposed as an “Eligible Futures Contract” for that index. The Eligible Futures Contract for the 2Y U.S. Treasury note futures index is a 2-Year T-Note Future traded on the CBOT, and the Eligible Futures Contract for the 10Y U.S. Treasury note futures index is a 10-Year T-Note Future traded on the CBOT. Periodically, over a period of 3 Constituent Index Business Days (the “Roll Period”), each U.S. Treasury note futures index rolls its hypothetical position out of the Eligible Futures Contract to which it is exposed immediately prior to such Roll Period (the “Current Contract”) and into a new Eligible Futures Contract (the “Next Contract”).

A “Constituent Index Business Day” is, with respect to each U.S. Treasury note futures index, each day which is a Scheduled Trading Day for the Exchange.

A “Scheduled Trading Day” means any day on which the Exchange is scheduled to be open for its regular trading session with respect to the relevant Eligible Futures Contracts (including any “partial trading day” however described as so designated from time to time by the Exchange).

“Exchange” means the CBOT.

Roll Periods occur at intervals of approximately three calendar months. Each Roll Period starts on the 4th Constituent Index Business Day immediately preceding the First Notice Day for the Current Contract and consists of 3 consecutive Constituent Index Business Days (each, a “Roll Day”), subject to adjustment for disruptions as described below. Over the course of each Roll Period, the hypothetical exposure of the applicable U.S. Treasury note futures index to the Current Contract decreases by the same proportion each day, and its hypothetical exposure to the Next Contract increases by the same proportion each day.

The “First Notice Day” is, in respect of the relevant Eligible Futures Contract, the first day on which the seller of such Eligible Futures Contract is entitled to serve a notice specifying the particular government bonds that such seller intends to deliver as part of the settlement process of such Eligible Futures Contract, under the terms of such Eligible Futures Contract and in accordance with the rules of the Exchange.

In respect of each Roll Period, the Next Contract is the Eligible Futures Contract the expiration month of which is the first to occur immediately following the expiration month of the Current Contract in respect of such Roll Period.

Calculation of the Level of the U.S. Treasury Note Futures Indices

The official closing level of each U.S. Treasury note futures index is calculated on each Constituent Index Business Day based on the settlement price of the underlying Eligible Futures Contract (or during a Roll Period, the underlying Eligible Futures Contracts) on that Constituent Index Business Day, determined by reference to

Bloomberg page “TU”, in the case of the 2Y U.S. Treasury note futures index, or “TY”, in the case of the 10Y U.S. Treasury note futures index (or, in each case, any successor or substitute page). The change in the closing level of each U.S. Treasury note futures index from one Constituent Index Business Day to the next will correspond to the percentage change in the settlement price of the underlying Eligible Futures Contract(s) over that same period.

Subject to the occurrence or existence of a Disrupted Day, the official closing level of each U.S. Treasury note futures index will be calculated as of 11:00 p.m. London time on each Constituent Index Business Day. The official closing level will be published on Bloomberg, under the ticker indicated above, generally on the following Constituent Index Business Day.

Adjustment Events

If an Adjustment Event occurs with respect to any Eligible Futures Contract for a U.S. Treasury note futures index (the “Affected Contract”), then:

An “Adjustment Event” with respect to any Eligible Futures Contract is each of the following:

An “Eligible Futures Contracts Cancellation” shall mean, with respect to any relevant Eligible Futures Contract, trading in such Eligible Futures Contract is permanently discontinued on the Exchange.

An “Eligible Futures Contracts Modification” shall mean, with respect to any relevant Eligible Futures Contract, the Exchange makes a material change to either:

Cancellation of any U.S. Treasury Note Futures Index

Citigroup Global Markets Limited may discontinue and cancel any U.S. Treasury note futures index at any time and is under no obligation to continue, or to procure the continuation of, the calculation, publication, and dissemination of either U.S. Treasury note futures index or its level.

Disrupted Days

If any Constituent Index Business Day (other than a Roll Day) is a Disrupted Day for any relevant Eligible Futures Contract, then the calculation, publication and dissemination of the applicable index will be suspended until

the first succeeding Constituent Index Business Day which is not a Disrupted Day for any relevant Eligible Futures Contract for that index.

If a scheduled Roll Day is a Disrupted Day for any relevant Eligible Futures Contract, then the calculation, publication and dissemination of the applicable index and its level will be suspended, and the Roll Day will be postponed, until the first succeeding Constituent Index Business Day which is not a Disrupted Day for any relevant Eligible Futures Contract.

A “Disrupted Day” means any Scheduled Trading Day on which an Exchange Disruption occurs or is continuing with respect to the relevant Eligible Futures Contract.

An “Exchange Disruption” means, with respect to any relevant Eligible Futures Contract:

“Scheduled Closing Time” means, with respect to any Scheduled Trading Day for the Exchange, the scheduled weekday closing time with respect to the relevant Eligible Futures Contract on the Exchange on such Scheduled Trading Day, without regard to after-hours trading or other trading outside the hours of the regular trading session on the Exchange.

“Settlement Price” means, with respect to the relevant Eligible Futures Contract, the daily settlement price or the final settlement price (as the case may be, and however described by the Exchange) of such Eligible Futures Contract, as published or otherwise made available by the Exchange.

If a Roll Day is postponed to a day after the Last Trading Day of an Eligible Futures Contract (whether or not such Last Trading Day is itself postponed by the Exchange), then the calculation agent of the applicable U.S. Treasury note futures index may publish its good faith estimate of the level of such U.S. Treasury note futures index, using its good faith estimate of the value of such Eligible Futures Contract affected by the occurrence of a Disrupted Day. Any such estimated value may be subject to correction once the relevant event or circumstances giving rise to such Disrupted Day cease. The “Last Trading Day” of an Eligible Futures Contract of a particular maturity is the day on which trading in the Eligible Futures Contract is scheduled to end on the Exchange.

Corrections

If the price of any Eligible Futures Contract for any time on any day, that is (1) announced by or on behalf of the person or entity responsible for such publication or announcement and (2) used for any calculation or determination in respect of a U.S. Treasury note futures index, is subsequently corrected, and the corrected price (the “Corrected Price”) is published by or on behalf of such person or entity within 2 Constituent Index Business Days, then such Corrected Price shall be deemed to be the price for such Eligible Futures Contract for the relevant time on the relevant day. The calculation agent for the applicable U.S. Treasury note futures index may, but will not be obliged to, make appropriate adjustments to the level of the applicable index for such day.

Regulatory Events

“Regulatory Event” shall mean that, owing to any applicable law or regulation or policy, the calculation agent for the U.S. Treasury note futures indices determines that either:

Following the occurrence of a Regulatory Event, the calculation agent of the U.S. Treasury note futures indices will determine whether or not such occurrence has a material effect on such indices.

Ambiguities, Errors and Omissions

It is possible that ambiguities, errors and omissions may arise in certain circumstances. Citigroup Global Markets Limited will resolve, using Expert Judgment, any such ambiguity, error or omission, and may amend the rules of the U.S. Treasury note futures indices to reflect the resolution of such ambiguity, error or omission.

Expert Judgment

Each of Citigroup Global Markets Limited and the calculation agent for the U.S. Treasury note futures indices, as relevant, will exercise any discretion and make any determination in respect of the indices by using a standard of judgement (“Expert Judgment”) which will consist of (1) acting in good faith and in a commercially reasonable manner; (2) to the extent practicable, reflecting the commercial objective of the indices and market practice; and (3) to the extent practicable, promoting consistency in the exercise of discretions and the making of determinations in respect of the U.S. Treasury note futures indices and other indices in respect of which it acts, as relevant, as index administrator or index calculation agent.

In using Expert Judgment to exercise any discretion or to make any determination, Citigroup Global Markets Limited will be subject to the oversight of the Index Governance Committee. In using Expert Judgment to exercise any discretion or to make any determination, the calculation agent for the U.S. Treasury note futures indices will be subject to the oversight of Citigroup Global Markets Limited. The Index Governance Committee will review any such use of Expert Judgment in extraordinary circumstances.

Index Governance

Citigroup Global Markets Limited has ultimate control over the development, the operation and the publication of the U.S. Treasury note futures indices, including the performance of any calculation, the exercise of any discretion, the making of any determination, and all administrative processes required to perform these functions (together, the “Index Activity”). Notwithstanding that certain parts of the Index Activity may be performed by persons other than Citigroup Global Markets Limited, Citigroup Global Markets Limited has overall responsibility for all parts of the Index Activity.

Citigroup Global Markets Limited maintains oversight over the Index Activity through its Index Governance Committee. The Index Governance Committee fulfils its role of ensuring accountability and providing oversight through (1) reviewing and challenging all parts of the Index Activity, in accordance with its charter and its written policies and procedures and (2) conducting an annual review of each U.S. Treasury note futures index to determine whether it continues to be an accurate and reliable representation of the economic realities of the relevant interest or market.

BENEFIT PLAN INVESTOR CONSIDERATIONS

A fiduciary of a pension, profit-sharing or other employee benefit plan subject to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), including entities such as collective investment funds, partnerships and separate accounts whose underlying assets include the assets of such plans (collectively, “ERISA Plans”), should consider the fiduciary standards of ERISA in the context of the ERISA Plan’s particular circumstances before authorizing an investment in the Notes. Among other factors, the fiduciary should consider whether the investment would satisfy the prudence and diversification requirements of ERISA and would be consistent with the documents and instruments governing the ERISA Plan.

Section 406 of ERISA and Section 4975 of the Internal Revenue Code of 1986, as amended, (the “Code”) prohibit ERISA Plans, as well as plans (including individual retirement accounts and Keogh plans) subject to Section 4975 of the Code (together with ERISA Plans, “Plans”), from engaging in certain transactions involving the “plan assets” with persons who are “parties in interest” under ERISA or “disqualified persons” under Section 4975 of the Code (in either case, “Parties in Interest”) with respect to such Plans. As a result of our business, we, and our current and future affiliates, may be Parties in Interest with respect to many Plans. Where we (or our affiliate) are a Party in Interest with respect to a Plan (either directly or by reason of our ownership interests in our directly or indirectly owned subsidiaries), the purchase and holding of the Notes by or on behalf of the Plan could be a prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless exemptive relief were available under an applicable exemption (as described below).

Certain prohibited transaction class exemptions (“PTCEs”) issued by the U.S. Department of Labor may provide exemptive relief for direct or indirect prohibited transactions resulting from the purchase or holding of the Notes. Those class exemptions are PTCE 96-23 (for certain transactions determined by in-house asset managers), PTCE 95-60 (for certain transactions involving insurance company general accounts), PTCE 91-38 (for certain transactions involving bank collective investment funds), PTCE 90-1 (for certain transactions involving insurance company separate accounts) and PTCE 84-14 (for certain transactions determined by independent qualified asset managers). In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code may provide a limited exemption for the purchase and sale of the Notes and related lending transactions, provided that neither the issuer of the Notes nor any of its affiliates have or exercise any discretionary authority or control or render any investment advice with respect to the assets of the Plan involved in the transaction and provided further that the Plan pays no more, and receives no less, than adequate consideration in connection with the transaction (the so-called “service provider exemption”). There can be no assurance that any of these statutory or class exemptions will be available with respect to transactions involving the Notes.

Accordingly, the Notes may not be purchased or held by any Plan, any entity whose underlying assets include “plan assets” by reason of any Plan’s investment in the entity (a “Plan Asset Entity”) or any person investing “plan assets” of any Plan, unless such purchaser or holder is eligible for the exemptive relief available under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14 or the service provider exemption or there is some other basis on which the purchase and holding of the Notes will not constitute a non-exempt prohibited transaction under ERISA or Section 4975 of the Code. Each purchaser or holder of the Notes or any interest therein will be deemed to have represented by its purchase or holding of the Notes that (a) it is not a Plan and its purchase and holding of the Notes is not made on behalf of or with “plan assets” of any Plan or (b) its purchase and holding of the Notes will not result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code.

Certain governmental plans (as defined in Section 3(32) of ERISA), church plans (as defined in Section 3(33) of ERISA) and non-U.S. plans (as described in Section 4(b)(4) of ERISA) (“Non-ERISA Arrangements”) are not subject to these “prohibited transaction” rules of ERISA or Section 4975 of the Code, but may be subject to similar rules under other applicable laws or regulations (“Similar Laws”). Accordingly, each such purchaser or holder of the Notes shall be required to represent (and deemed to have represented by its purchase of the Notes) that such purchase and holding is not prohibited under applicable Similar Laws.

Due to the complexity of these rules, it is particularly important that fiduciaries or other persons considering purchasing the Notes on behalf of or with “plan assets” of any Plan consult with their counsel regarding the relevant provisions of ERISA, the Code or any Similar Laws and the availability of exemptive relief under PTCE 96-23, 95-60, 91-38, 90-1, 84-14, the service provider exemption or some other basis on which the acquisition and holding will

not constitute a non-exempt prohibited transaction under ERISA or Section 4975 of the Code or a violation of any applicable Similar Laws.

The Notes are contractual financial instruments. The financial exposure provided by the Notes is not a substitute or proxy for, and is not intended as a substitute or proxy for, individualized investment management or advice for the benefit of any purchaser or holder of the Notes. The Notes have not been designed and will not be administered in a manner intended to reflect the individualized needs and objectives of any purchaser or holder of the Notes.

Each purchaser and holder of the Notes has exclusive responsibility for ensuring that its purchase, holding and subsequent disposition of the Notes does not violate the fiduciary or prohibited transaction rules of ERISA, the Code or any applicable Similar Laws. The sale of any Notes to any Plan is in no respect a representation by us or any of our affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by Plans or Non-ERISA Arrangements generally or any particular Plan or Non-ERISA Arrangement, or that such an investment is appropriate for Plans or Non-ERISA Arrangements generally or any particular Plan or Non-ERISA Arrangement.

However, individual retirement accounts, individual retirement annuities and Keogh plans, as well as employee benefit plans that permit participants to direct the investment of their accounts, will not be permitted to purchase or hold the Notes if the account, plan or annuity is for the benefit of an employee of CGMI or a family member and the employee receives any compensation (such as, for example, an addition to bonus) based on the purchase of Notes by the account, plan or annuity.

UNITED STATES FEDERAL TAX CONSIDERATIONS

The following is a discussion of the material U.S. federal income and certain estate tax consequences of the ownership and disposition of the notes. It applies to you only if you purchase a note for cash in the initial offering at the “issue price,” which is the first price at which a substantial amount of the notes is sold to the public (not including sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers), and hold it as a capital asset within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”). Purchasers of notes at another time or price should consult their tax advisers regarding the U.S. federal tax consequences to them of the ownership and disposition of the notes. This discussion does not address all of the tax consequences that may be relevant to you in light of your particular circumstances or if you are a holder subject to special rules, such as:

If an entity that is classified as a partnership for U.S. federal income tax purposes holds the notes, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. If you are a partnership holding the notes or a partner in such a partnership, you should consult your tax adviser as to the particular U.S. federal tax consequences of holding and disposing of the notes to you.

We will not attempt to ascertain whether any ETF to which the notes relate should be treated as a “U.S. real property holding corporation” (“USRPHC”) within the meaning of Section 897 of the Code or a “passive foreign investment company” (“PFIC”) within the meaning of Section 1297 of the Code. If any ETF were so treated, certain adverse U.S. federal income tax consequences might apply to you in the case of a USRPHC if you are a Non-U.S. Holder (as defined below), and in the case of a PFIC if you are a U.S. Holder, upon a sale, exchange or other disposition of the notes. If a U.S. Holder owns or is deemed to own an equity interest in a PFIC for any taxable year, the U.S. Holder would generally be required to file IRS Form 8621 with its annual U.S. federal income tax return for that year, subject to certain exceptions. Failure to timely file the form may extend the time for tax assessment by the IRS. You should refer to information filed with the Securities and Exchange Commission or another governmental authority by the ETFs and consult your tax adviser regarding the possible consequences to you if any ETF is or becomes a USRPHC or PFIC.

This discussion is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, all as of the date of this index supplement, changes to any of which subsequent to the date of this index supplement may affect the tax consequences described herein, possibly with retroactive effect. This discussion does not address the effects of any applicable state, local or non-U.S. tax laws or the potential application of the Medicare contribution tax or the alternative minimum tax. You should consult your tax adviser about the application of the U.S. federal income and estate tax laws (including the possibility of alternative treatments of the notes) to your particular situation, as well as any tax consequences arising under the laws of any state, local or non-U.S. jurisdiction.

This discussion may be supplemented, modified or superseded by disclosure regarding U.S. federal tax consequences set out in an applicable pricing supplement, which you should read before making a decision to invest in the relevant notes.

Tax Treatment of the Notes

Unless otherwise indicated in the applicable pricing supplement, we intend to treat the notes as debt instruments for U.S. federal income tax purposes, and the discussion herein is based on this treatment. With respect to notes with a term of longer than one year (calculated as described below), the applicable pricing supplement will specify whether we intend to treat such notes as “variable rate debt instruments” or as “contingent payment debt instruments,” each as discussed below.

The discussion below is subject to, and should be read in conjunction with, the discussion below under “Possible Taxable Event.”

Tax Consequences to U.S. Holders

This section applies only to U.S. Holders. You are a “U.S. Holder” if for U.S. federal income tax purposes you are a beneficial owner of a note that is:

Short-Term Notes

The following discussion applies only to notes with a term of one year or less (from but excluding the issue date to and including the last possible date that the notes could be outstanding pursuant to their terms) (“short-term notes”). Generally, a short-term note is treated as issued at a discount equal to the sum of all payments required on the note minus its issue price.

If you are a cash-method U.S. Holder, you generally will not be required to recognize income with respect to a short-term note prior to maturity, other than with respect to the receipt of interest payments, if any, or pursuant to a sale or other taxable disposition of the note. If you are an accrual-method U.S. Holder (or a cash-method U.S. Holder who elects to accrue income on the note currently), you will be subject to rules that generally require accrual of discount on short-term notes on a straight-line basis, unless you elect a constant-yield method of accrual based on daily compounding. In the case of short-term notes that provide for one or more contingent payments, it is not clear whether or how any accrual should be determined prior to the relevant Valuation Date(s) in respect of a payment. You should consult your tax adviser regarding the amount and timing of any accruals on such notes.

Upon a taxable disposition (including a sale, exchange, early redemption or retirement) of a short-term note, you will generally recognize gain or loss equal to the difference between the amount realized on the sale or other taxable disposition and your tax basis in the note. Your tax basis in the note should equal the amount you paid to acquire the note increased, if you accrue income on the notes currently, by any previously accrued but unpaid discount. The amount of any resulting loss generally will be treated as a short-term capital loss, the deductibility of which is subject to limitations. The excess of the amount received at maturity over your tax basis in the note generally should be treated as ordinary income. If you sell a short-term note providing for a contingent payment at maturity prior to the time the contingent payment has been fixed, it is not clear whether any gain you recognize should be treated as ordinary income, short-term capital gain, or a combination of ordinary income and short-term capital gain. You should consult your tax adviser regarding the treatment of a taxable disposition of short-term notes providing for contingent payments.

If you are a cash-method U.S. Holder, unless you make the election to accrue income currently on a short-term note, you will generally be required to defer deductions for interest paid on indebtedness incurred to purchase or carry the note in an amount not exceeding the accrued discount that you have not included in income. As discussed above, in the case of a short-term note providing for a contingent payment, it is unclear whether or how accrual of discount should be determined prior to the relevant Valuation Date(s) in respect of the payment. If you make the election to accrue income currently, that election will apply to all short-term debt instruments acquired by you on or

after the first day of the first taxable year to which that election applies. You should consult your tax adviser regarding these rules.

Notes Treated as Variable Rate Debt Instruments

The following discussion applies only to notes treated as variable rate debt instruments for U.S. federal income tax purposes (“VRDIs”) and that provide for stated interest at a single variable rate. The treatment of other VRDIs will be addressed in the applicable pricing supplement.

Stated interest on a VRDI will be treated as “qualified stated interest” (“QSI”) and will be taxable to you as ordinary interest income at the time it accrues or is received, in accordance with your method of accounting for U.S. federal income tax purposes. If the stated principal amount of a VRDI exceeds its issue price by at least a specified de minimis amount, this excess will be treated as “original issue discount” (“OID”) that you must include in income as it accrues in accordance with a constant-yield method based on compounding of interest before the receipt of cash payments attributable to this income.

Upon the sale or other taxable disposition of a VRDI, you generally will recognize capital gain or loss equal to the difference between the amount realized (other than amounts attributable to accrued QSI, which will be treated as described above) and your tax basis in the VRDI. Your tax basis in a VRDI will equal the amount you paid to purchase the VRDI, increased by the amounts of OID (if any) you previously included in income with respect to the VRDI and reduced by any payments other than QSI you received. Such gain or loss generally will be long-term capital gain or loss if you held the VRDI for more than one year at the time of disposition. The deductibility of capital losses is subject to limitations.

Notes Treated as Contingent Payment Debt Instruments

The following discussion applies only to notes treated as contingent payment debt instruments for U.S. federal income tax purposes (“CPDIs”).

We are required to determine a “comparable yield” for each issuance of CPDIs. The comparable yield is the yield at which we could issue a fixed-rate debt instrument with terms similar to those of the CPDIs, 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 CPDIs. Solely for purposes of determining the amount of interest income that you will be required to accrue, we are also required to construct a “projected payment schedule” in respect of the CPDIs representing a payment or a series of payments the amount and timing of which would produce a yield to maturity on the CPDIs equal to the comparable yield.

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

For U.S. federal income tax purposes, you are required to use our determination of the comparable yield and projected payment schedule in determining interest accruals and adjustments in respect of the CPDIs, unless you timely disclose and justify the use of other estimates to the IRS. Regardless of your method of accounting for U.S. federal income tax purposes, you will be required to accrue, as interest income, OID on the CPDIs at the comparable yield, adjusted upward or downward to reflect the difference, if any, between the actual and the projected payments on the CPDIs during the year (as described below).

You will be required for U.S. federal income tax purposes to accrue an amount of OID, for each accrual period prior to and including the maturity (or earlier sale or other taxable disposition) of a CPDI, that equals the product of (i) the “adjusted issue price” of the CPDI (as defined below) as of the beginning of the accrual period, (ii) the comparable yield of the CPDI, adjusted for the length of the accrual period and (iii) the number of days during the accrual period that you held the CPDI divided by the number of days in the accrual period. The adjusted issue price of a CPDI is its issue price increased by any interest income you have previously accrued (determined without regard to adjustments due to differences between projected and actual payments) and decreased by the projected amounts of any payments previously made on the CPDI (without regard to actual amounts paid).

In addition to interest accrued based upon the comparable yield as described above, you will be required to recognize interest income equal to the amount of any net positive adjustment (i.e., the excess of actual payments

over projected payments) in respect of a CPDI for a taxable year. A net negative adjustment (i.e., the excess of projected payments over actual payments) in respect of a CPDI for a taxable year:

A net negative adjustment is not treated as a miscellaneous itemized deduction (for which deductions would be unavailable or, beginning in 2026, available only to a limited extent). Any net negative adjustment in excess of the amounts described above may be carried forward to offset future interest income in respect of the CPDI or to reduce the amount realized on a sale or other taxable disposition of the CPDI.

Upon a sale or other taxable disposition of a CPDI, you generally will recognize taxable income or loss equal to the difference between the amount received and your tax basis in the CPDI. Your tax basis in the CPDI will equal your purchase price for the CPDI increased by any interest income you have previously accrued (determined without regard to adjustments due to differences between projected and actual payments) and decreased by the projected amounts of any payments previously made on the CPDI (without regard to actual amounts paid). At maturity, you will be treated as receiving the projected amount for that date, and any difference between the amount actually received and that projected amount will be treated as a positive or negative adjustment governed by the rules described above. As described above, the amount you are treated as receiving upon a disposition of a CPDI, whether at or prior to maturity, will be reduced by any carryforward of a net negative adjustment. You generally must treat any income as interest income and any loss as ordinary loss to the extent of previous interest inclusions (reduced by the total amount of net negative adjustments previously taken into account as ordinary losses), and the balance as capital loss. These losses are not treated as miscellaneous itemized deductions. The deductibility of capital losses is, however, subject to limitations. Additionally, if you recognize a loss above certain thresholds, you may be required to file a disclosure statement with the IRS. You should consult your tax adviser regarding this reporting obligation.

Special rules may apply if all the remaining payments on a CPDI become fixed substantially contemporaneously. For this purpose, payments will be treated as fixed if the remaining contingencies with respect to them are remote or incidental. Under these rules, you would be required to account for the difference between the originally projected payments and the fixed payments in a reasonable manner over the period to which the difference relates. In addition, you would be required to make adjustments to, among other things, your accrual periods and your tax basis in the CPDI. The character of any gain or loss on a sale or other taxable disposition of your CPDI also might be affected. If one or more (but not all) contingent payments on a CPDI became fixed more than six months prior to the relevant payment dates, you would be required to account for the difference between the originally projected payments and the fixed payments on a present value basis. You should consult your tax adviser regarding the application of these rules.

Tax Consequences to Non-U.S. Holders

This section applies only to Non-U.S. Holders. You are a “Non-U.S. Holder” if for U.S. federal income tax purposes you are a beneficial owner of a note that is:

You are not a Non-U.S. Holder for purposes of this discussion if you are (i) an individual who is present in the United States for 183 days or more in the taxable year of disposition or (ii) a former citizen or resident of the United States and certain conditions apply. If you are or may become such a person during the period in which you hold a note, you should consult your tax adviser regarding the U.S. federal tax consequences of an investment in the notes.

Subject to the possible application of Section 897 of the Code (see “FIRPTA” below) and the discussions below under “—Dividend Equivalents Under Section 871(m) of the Code” and “FATCA,” you generally will not be subject to U.S. federal withholding or income tax in respect of payments on or amounts you receive on a sale or other taxable disposition of a note, 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 provide an appropriate IRS Form W-8 to the applicable withholding agent certifying under penalties of perjury that you are not a United States person.

If you are engaged in a U.S. trade or business, and if income from the notes is effectively connected with your conduct of that trade or business, you generally will be subject to regular U.S. federal income tax with respect to that income in the same manner as if you were a U.S. Holder, subject to the provisions of an applicable income tax treaty. In this event, if you are a corporation, you should also consider the potential application of a 30% (or lower treaty rate) branch profits tax.

Dividend Equivalents Under Section 871(m) of the Code

Section 871(m) of the Code and the Treasury regulations thereunder (“Section 871(m)”) impose a 30% (or lower treaty rate) 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 (“Underlying Securities”), as defined under the applicable Treasury regulations, or indices that include Underlying Securities. Section 871(m) generally applies to “specified equity-linked instruments” (“Specified ELIs”), which are financial instruments that substantially replicate the economic performance of one or more Underlying Securities, as determined based on tests set forth in the applicable Treasury regulations and discussed further below. Section 871(m) provides certain exceptions to this withholding regime, in particular for instruments linked to certain broad-based indices that meet requirements set forth in the applicable Treasury regulations (“Qualified Indices”) as well as securities that track such indices (“Qualified Index Securities”).

Although the Section 871(m) regime became effective in 2017, Treasury regulations, as modified by an IRS notice, phase in the application of Section 871(m) as follows:

Delta is generally defined as the ratio of the change in the fair market value of a financial instrument to a small change in the fair market value of the number of shares of the Underlying Security. The “substantial equivalence” test measures whether a complex contract tracks its “initial hedge” (shares of the Underlying Security that would fully hedge the contract) more closely than would a “benchmark” simple contract with a delta of 0.80.

The calculations are generally made at the “calculation date,” which is the earlier of (i) the time of pricing of the note, i.e., when all material terms have been agreed on, and (ii) the issuance of the note. However, if the time of pricing is more than 14 calendar days before the issuance of the note, the calculation date is the date of the issuance of the note. In those circumstances, information regarding our final determinations for purposes of Section 871(m) may be available only after the time of pricing of the note. As a result, you should acquire such a note only if you are willing to accept the risk that the note is treated as a Specified ELI subject to withholding under Section 871(m).

If the terms of a note are subject to a “significant modification” (for example, upon an event discussed below under “Possible Taxable Event”), the note generally will be treated as reissued for this purpose at the time of the significant modification, in which case the notes could become Specified ELIs at that time.

If a note is a Specified ELI, withholding in respect of dividend equivalents will, depending on the applicable withholding agent’s circumstances, generally be required either (i) on the underlying dividend payment date or (ii) when cash payments are made on the note or upon the date of maturity, lapse or other disposition of the note by you, or possibly upon certain other events. Depending on the circumstances, the applicable withholding agent may withhold the required amounts from coupons or other payments on the note, from proceeds of the retirement or other disposition of the note, or from your other cash or property held by the withholding agent.

The dividend equivalent amount will include the amount of any actual or, under certain circumstances, estimated dividend. If the dividend equivalent amount is based on the actual dividend, it will be equal to the product of: (i) in the case of a “simple” contract, the per-share dividend amount, the number of shares of an Underlying Security and the delta; or (ii) in the case of a “complex” contract, the per-share dividend amount and the initial hedge. The dividend equivalent amount for Specified ELIs issued prior to 2023 that have a “delta” of one will be calculated in the same manner as (i) above, using a “delta” of one. The per-share dividend amount will be the actual dividend (including any special dividends) paid with respect to a share of the Underlying Security. If the dividend equivalent amount is based on an estimated dividend, the applicable pricing supplement will generally state the estimated amounts.

Depending on the terms of a note and whether or not it is issued prior to 2023, the pricing supplement may contain additional information relevant to Section 871(m), such as whether the note references a Qualified Index or Qualified Index Security; whether it is a “simple” contract; the “delta” and the number of shares multiplied by delta (for a simple contract); and whether the “substantial equivalence test” is met and the initial hedge (for a complex contract).

Prospective purchasers of the notes should consult their tax advisers regarding the potential application of Section 871(m) to a particular note and, if withholding applies, whether they are eligible for a refund of any part of the withholding tax discussed above on the basis of an applicable U.S. income tax treaty, as well as the process for obtaining such a refund (which will generally require the filing of a U.S. federal income tax return). In some circumstances, it may not be possible for a Non-U.S. Holder to obtain the documentation necessary to support a refund claim under an applicable treaty. Our determination is binding on Non-U.S. Holders and withholding agents, but it is not binding on the IRS. The Section 871(m) regulations require complex calculations to be made with respect to notes linked to U.S. equities and their application to a specific issue of notes may be uncertain. Accordingly, even if we determine that certain notes are not Specified ELIs, the IRS could challenge our determination and assert that withholding is required in respect of those notes. Moreover, your consequences under Section 871(m) may depend on your particular circumstances. For example, if you enter into other transactions relating to an Underlying Security, you could be subject to withholding tax or income tax liability under Section 871(m) even if the notes are not Specified ELIs subject to Section 871(m) as a general matter. Non-U.S. Holders should consult their tax advisers regarding the application of Section 871(m) in their particular circumstances.

We will not be required to pay any additional amounts with respect to U.S. federal withholding taxes.

FIRPTA

Section 897 of the Code, commonly referred to as “FIRPTA,” applies to certain interests in entities that beneficially own significant amounts of United States real property interests (each, a “USRPI”). As discussed above, we will not attempt to ascertain whether any issuer of the ETF should be treated as a USRPHC for purposes of Section 897 of the Code (including a non-corporate entity treated for relevant purposes of Section 897 of the Code as a USRPHC). If a relevant issuer were so treated, it is possible that, subject to the exceptions discussed in the following paragraph, a note could be treated as a USRPI, in which case any gain from the disposition of the note would generally be subject to U.S. federal income tax and would be required to be reported by the Non-U.S. Holder on a U.S. federal income tax return, generally in the same manner as if the Non-U.S. Holder were a U.S. Holder, and would in certain cases be subject to withholding in the amount of 15% of the gross proceeds of such disposition.

An exception to the FIRPTA rules applies in respect of interests in entities that have a regularly traded class of interests outstanding. Under this exception, a note that is not “regularly traded” on an established securities market generally should not be subject to the FIRPTA rules unless its fair market value upon acquisition exceeds 5% of the relevant issuer's regularly traded class of interests as specified in the applicable Treasury regulations. In the case of notes that are regularly traded, a holding of 5% or less of the outstanding notes of that class or series generally should not be subject to the FIRPTA rules. Certain attribution and aggregation rules apply, and prospective purchasers are urged to consult their tax advisers regarding whether their ownership interest in the notes will be subject to an exemption from the FIRPTA rules in light of their circumstances, including any other interest they might have in a relevant issuer.

U.S. Federal Estate Tax

If you are an individual Non-U.S. Holder or an entity the property of which is potentially includible in such an individual’s gross estate for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), you should note that, absent an applicable treaty exemption, a note that is treated as a debt obligation for U.S. federal estate tax purposes generally will be treated as U.S.-situs property subject to U.S. federal estate tax if payments on the note, if received by the decedent at the time of death, would have been subject to U.S. federal withholding or income tax (even if the IRS Form W-8 certification requirement described above were satisfied and not taking into account the elimination of such U.S. federal withholding tax due to the application of an income tax treaty). If you are such an individual or entity, you should consult your tax adviser regarding the U.S. federal estate tax consequences of an investment in the notes.

Possible Taxable Event

A change in the methodology by which the Index is calculated, a change in the components of the Index, the designation of a Successor Index, an assumption of the notes (as discussed in the paragraph below) or other similar circumstances resulting in a material change to an underlying or to the method by which amounts payable are determined on the notes could result in a “significant modification” of the affected notes.

As provided in the accompanying prospectus under “Description of Debt Securities — Citigroup Guarantees,” our obligations under the notes may be assumed by Citigroup Inc. We intend that Citigroup Inc. will assume the notes pursuant to this provision only in circumstances in which we expect to treat such an assumption as not giving rise to a “significant modification” of the notes and have been advised by our counsel that such treatment is reasonable under the circumstances and the law in effect at the time of such assumption. However, in light of the lack of clear authority regarding the treatment of such an assumption, there may be uncertainty regarding the correctness of this treatment. As a result, it is possible that the IRS may treat an assumption of the notes as a significant modification.

A significant modification of the securities would generally result in the notes being treated as terminated and reissued for U.S. federal income tax purposes. In that event, you might be required to recognize gain or loss (subject to the possible application of the wash sale rules) with respect to the notes, and your holding period for your notes could be affected. Moreover, depending on the facts at the time of the significant modification, the reissued notes could be characterized for U.S. federal income tax purposes in a manner different from their original treatment, which could have a significant and potentially adverse effect on the timing and character of income you recognize with respect to the notes after the significant modification if you are a U.S. Holder, and potentially adverse withholding consequences if you are a Non-U.S. Holder.

You should consult your tax adviser regarding the consequences of a significant modification of the notes. Except where stated otherwise, the discussion herein assumes that there has not been a significant modification of the securities.

Information Reporting and Backup Withholding

Payments on the notes, as well as the proceeds of a sale, exchange or other disposition (including retirement) of the notes, may be subject to information reporting and, if you fail to provide certain identifying information (such as an accurate taxpayer identification number if you are a U.S. Holder) or meet certain other conditions, may also be subject to backup withholding at the rate specified in the Code. If you are a Non-U.S. Holder that provides the applicable withholding agent with the appropriate IRS Form W-8, you will generally establish an exemption from backup withholding. Amounts withheld under the backup withholding rules are not additional taxes and may be refunded or credited against your U.S. federal income tax liability, provided the relevant information is timely furnished to the IRS.

FATCA

Legislation commonly referred to as “FATCA” generally imposes a withholding tax of 30% on payments to certain non-U.S. entities (including financial intermediaries) with respect to certain financial instruments, unless various U.S. information reporting and due diligence requirements (that are in addition to, and potentially significantly more onerous than, the requirement to deliver an IRS Form W-8) have been satisfied. An intergovernmental agreement between the United States and the non-U.S. entity’s jurisdiction may modify these

requirements. This legislation generally applies to interest on the notes and certain dividend equivalents (as defined above) under Section 871(m). While existing Treasury regulations would also require withholding on payments of gross proceeds of the disposition (including upon retirement) of the notes, the U.S. Treasury Department has indicated in subsequent proposed regulations its intent to eliminate this requirement. The U.S. Treasury Department has stated that taxpayers may rely on these proposed regulations pending their finalization. If you are a Non-U.S. Holder, or a U.S. Holder holding notes through a non-U.S. intermediary, you should consult your tax adviser regarding the potential application of FATCA to the notes, including the availability of certain refunds or credits.

WE WILL NOT BE REQUIRED TO PAY ANY ADDITIONAL AMOUNTS WITH RESPECT TO U.S. FEDERAL WITHHOLDING TAXES.

ANNEX A

INDEX RULES

This document constitutes the “Index Conditions” in respect of the following indices (each, an “Index”).

Each Index is referred to in these Index Conditions by its short name (as specified above under the heading “Short Name”).

For the avoidance of doubt, references in these Index Conditions to “the Index” or “an Index” shall be references to each of the Indices.  

These Index Conditions are made available by Citigroup Global Markets Limited in its capacity as the Index Administrator.

Full information in respect of any Index Linked Product is only available on the basis of a combination of these Index Conditions and the confirmation, prospectus or offering document (however described) in respect of such Index Linked Product. Particular attention is drawn to the important risk factors and disclaimers contained in these Index Conditions, and investors should be aware of the consequences set out in such confirmation, prospectus or offering document of such Index Linked Product of any discontinuation of the Index.

No use of the Index or these Index Conditions is permitted unless such use is authorised, whether: (1) through buying, or otherwise entering into, an Index Linked Product from or with the Index Administrator or the Index Calculation Agent or one of their respective Affiliates; or (2) under the terms of a written licence granted by the Index Administrator.

These Index Conditions may be amended from time to time in the circumstances described in Part L (Miscellaneous). Copies of these Index Conditions are available from the Index Administrator.

These Index Conditions replace an earlier edition dated 9 May 2019, and have been prepared to add two variations, with Volatility Targets specified as 3.5% and 4%.

These Index Conditions comprise the following Parts.

The Index was launched by the Index Administrator on the Index Launch Date. The Index has been calculated by the Index Calculation Agent for the period from the Index Start Date. The past performance of the Index prior to the Index Launch Date has been derived from a back-testing simulation by applying the Index methodology to published historical levels of the Index constituents. Back-tested performance is provided for illustrative purposes only and should not be regarded as an indication of future performance. The back-testing simulation assumed that there were no market disruption events and no extraordinary events affecting Index constituents. A simulation based on different assumptions may produce different results. Any Index Linked Product may bear additional fees which will reduce the overall returns of such Index Linked Product as compared with the past performance of the Index.

The calculations and determinations in this Part D (Calculation of the Index Level) are subject to the occurrence of, and adjustments made as a consequence of, Disrupted Days (as described in Part G (Adjustment of dates)) and Adjustment Events (as described in both Part H (Adjustments, disruption and cancellation) and Part I (Provisions relating to Constituents)).

1. DAILY INDEX CALCULATION

1.1       Index Level

The “Index Level” as at the Index Start Date shall be 100 (the Index Start Level).

The “Index Level” as at each Index Business Day t following the Index Start Date shall be an amount determined by the Index Calculation Agent as at the Index Valuation Time on such Index Business Day t in accordance with the following formula:

where:

1.2       Gross Index Level

The “Gross Index Level” as at the Index Start Date shall be 100 (the Index Start Level).

The “Gross Index Level” as at each Index Business Day t following the Index Start Date shall be an amount determined by the Index Calculation Agent as at the Index Valuation Time on such Index Business Day t in accordance with the following formula:

where:

1.3       Core Index Level

The “Core Index Level” as at the Core Index Start Date shall be 100.

The “Core Index Level” as at each Index Business Day t falling after the Core Index Start Date shall be an amount determined by the Index Calculation Agent on such Index Business Day t in accordance with the following formula:

where:

1.4       Exposure and Realized Volatility of Core Index

The Exposure of the Gross Index Level to the Core Index Level is determined by reference to the short term Realized Volatility of the Core Index calculated over a window of observation of the Core Index Level of 21 Index Business Days. This means that the Realized Volatility is calculated by reference to 22 observed values of the Core Index Level, commencing on (and including) the 21st Index Business Day prior to Index Business Day t and ending on (and including) Index Business Day t (i.e. 21 values of

.

For each of Radar 3.5, Radar 4 and Radar 5, the Exposure of the Index Level to the Core Index Level will never be more than 100 per cent, whereas for Radar 7, the Exposure of the Index Level to the Core Index Level will never be more than 120 per cent. The Exposure of the Index Level to the Core Index Level shall never be less than 0 per cent.

The “Exposure” (exp_t) in respect of the Index Start Date shall be 100 per cent.

The “Exposure” (exp_t) in respect of each Index Business Day (following the Index Start Date) shall be an amount (expressed as a percentage) determined by the Index Calculation Agent in accordance with the following formula:

where:

1.5       Weight of Constituents of Core Index

As at each Index Business Day t that:

in each case, where:

2. DETERMINATION OF PERCENTAGE WEIGHT AND REBALANCING PROCESS

2.1 Determination of Percentage Weight

As at each Selection Date, the Index Calculation Agent shall determine, in accordance with the methodology set out below, the respective Percentage Weights that shall be allocated to each Constituent i from, but excluding, the Rebalancing Date immediately following such Selection Date to, and including, the second Rebalancing Date immediately following such Selection Date, as follows:

Where:

2.2 Determination of Raw Percentage Weight

As at each Index Business Day, the Index Calculation Agent shall determine, in accordance with the methodology set out below, the respective Raw Percentage Weights, as follows:

where:

For the avoidance of doubt, the Index will allocate exposure to the NR Group in the case of Market Regime 2 (i.e. when rates have not risen consistently), and will allocate to the R Group in case of Market Regime 1 (i.e. when rates have been rising consistently).

2.2.1 Determination of Market Regime

For the purposes of determining whether a Signal Change Date has arisen (and determining the Percentage Weight of each Constituent in respect of such Selection Date), as at each Index Business Day t (starting on the first Selection Date), the Index Calculation Agent shall determine the applicable Market Regime (Market Regime 1 or Market Regime 2).

This involves the Index Calculation Agent calculating the Rates Signal, which is a value intended to represent whether the 3 month Libor rate has been rising or not, as determined in accordance with paragraph 2.2.2 (Determination of Rates Signal) of this Part D (Calculation of the Index Level) (the “Rates Signal”).

The Index Calculation Agent shall determine the Market Regime (Market Regime 1 or Market Regime 2) as at each Index Business Day, starting on (and including) the first Selection Date, as follows:

If on an Index Business Day the Rates Signal on such Index Business Day is different to the Rates Signal on the immediately preceding Index Business Day, then such Index Business Day shall be a Signal Change Date.

2.2.2 Determination of Rates Signal

The rationale behind the Rates Signal is to identify whether rates have been rising within a fixed observation window. The Rates Signal shall be determined as at each Index Business Day t by the Index Calculation Agent observing the average US 3M Libor Rate (the “Smoothed US 3M Libor Rate”) on Index Business Day t, 21 Index Business Days prior to Index Business Day t, 42 Index Business Days prior to Index Business Day t and 63 Index Business Day prior to Index Business Day t and if it is consistently increasing determine that this is Rates increasing environment (i.e. Rates Signal = 1) otherwise it is not a Rates increasing environment (i.e. Rates Signal =0).

The Index Calculation Agent shall determine the Signal as at each Index Business Day in accordance with the following formula:

where:

where:

2. 3 Determination of Equity Current Volatility

The “Equity Current Volatility” represents the recent realized volatility of the returns of the three NR ETFs and the three R ETFs (each, an “Equity Constituent”). The Equity Current Volatility shall be determined as at each Index Business Day t by the Index Calculation Agent observing the Constituent Closing Level of the Equity Current Level over an observation window of 126 Index Business Days. This means that the Equity Current Volatility is calculated by reference to 127 observed values of the Equity Current Level, commencing on (and including) the 126th Index Business Day prior to Index Business Day t and ending on (and including) Index Business Day t (i.e. 126 values of ).

The Index Calculation Agent shall determine the Equity Current Volatility as at each Index Business Day in accordance with the following formula:

where:

2.3.1       Determination of Equity Current Level

The “Equity Current Level” as at each Index Business Day k and as at Index Business Day t shall be an amount determined by the Index Calculation Agent on such Index Business Day k in accordance with the following formula:

where:

2.3.2       Determination of Equity Current Weights

The “Equity Current Weight” as at each Index Business Day t of each Equity Constituent i shall be an amount determined by the Index Calculation Agent on such Index Business Day t in accordance with the following formula:

where:

The “Equity Index Level” as at the Equity Index Start Date shall be 100.

The “Equity Index Level” as at any Index Business Day t following the Equity Index Start Date, shall be an amount determined by the Index Calculation Agent on such Index Business Day t in accordance with the following formula:

where:

The “Equity Weights” as at each Index Business Day t of each Equity Constituent i shall be an amount determined by the Index Calculation Agent on such Index Business Day t in accordance with the following formula:

where:

3. DETERMINATION OF INDEX CONSTITUENT LEVEL

3.1 In respect of each of Constituent 1 to Constituent 6 (inclusive) (each Equity Constituent)

The “Index Constituent Level” of each of Constituent 1 to Constituent 6 (inclusive) as at the ETF Start Date of such Constituent shall be 100

The “Index Constituent Level” of each of Constituent 1 to Constituent 6 (inclusive) “i” as at each Index Business Day “t” (following the ETF Start Date of such Constituent) shall be an amount calculated by the Index Calculation Agent in accordance with the following formula:

where:

For each Constituent i, prior to the respective US-UP Cross Over Date in respect of i (see the Annex to Part E below), the Index Constituent Level is calculated using the US ETF Total Return of such Constituent.

3.1.1        Total Return

As of each Total Return Business Day t for Constituent i, the Calculation Agent shall calculate the “Total Return Level” for each Constituent i in accordance with the following formula:

where:

3.1.2        Adjustment Factors

3.1.2.1        Dividend Adjustments

Following the declaration by the issuer of any Constituent of a Cash Dividend (as defined below) (a “Dividend Adjustment Event”), the Index Calculation Agent shall calculate the adjustment factor in respect of such Cash Dividend and apply the outcome of the below formula to the product of all Adjustment Factors in accordance with paragraph 3.1.1 (Total Return) above.

An Adjustment Factor in respect of any Cash Dividend paid in relation to the Constituent shall be determined by the Index Calculation Agent in accordance with the following formula:

where:

“Cash Dividend” means, in respect of an Constituent, any regular dividend (in the form of a cash dividend only) declared by the issuer of such Constituent for which the Ex-Dividend Date falls on any day after the Index Start Date (excluding any Extraordinary Dividend).

“Ex-Dividend Date” means, in respect of a share and a dividend payment which has been announced by the issuer of such share, the first day on which a purchaser of such share will not be entitled to receive the relevant dividend payment, as fixed by the issuer of such share and/or the primary exchange on which such share is traded.

3.1.2.2       Share Split or Stock Dividend Adjustments

Following the declaration by the issuer of an Constituent of a Share Split (a “Share Split Adjustment Event”) or a Stock Dividend (a “Stock Dividend Adjustment Event”), the Index Calculation Agent shall calculate the adjustment factor in respect of such Share Split or Stock Dividend (as the case may be) in respect of the Ex-Date and apply the outcome of the below formula to the product of all Adjustment Factors in accordance with paragraph 3.1.1 (Total Return) above.

An Adjustment Factor in respect of a Share Split Event or Stock Dividend Adjustment Event (as the case may be) in relation to the Constituent shall be determined by the Index Calculation Agent in accordance with the following formula:

where:

“Ex- Date” means, in respect of a Share Split or a Stock Dividend (as the case may be) in respect of an Constituent, the effective date of such Share Split, as fixed by the issuer of such Constituent and/or the primary exchange on which such Constituent is traded.

“Share Split” means, in respect of a Constituent, a share split, subdivision, reverse share split, consolidation or similar reclassification of the share of such Constituent, for which the Ex-Date falls on any day after the Index Start Date.

“Stock Dividend” means, in respect of a Constituent, a dividend (in the form of a stock dividend) of such Constituent declared by the issuer of such Constituent, for which the Ex-Date falls on any day after the Index Start Date (excluding any Extraordinary Dividend).

3.1.2.3       Extraordinary Dividend Adjustment

Following the declaration by the issuer of an Constituent of an Extraordinary Dividend (as defined below) (an “Extraordinary Dividend Adjustment Event”), the Index Calculation Agent shall calculate the adjustment factor in respect of such Extraordinary Dividend in accordance with the formula set out below and apply the outcome of the below formula to the product of all Adjustment Factors in accordance with paragraph 3.1.1 (Total Return ) above. If such Ex-Dividend Date is not an Index Business Day, the adjustment shall be made on the next following Index Business Day.

An Adjustment Factor in respect of any Extraordinary Dividend paid in relation to the Constituent shall be determined by the Index Calculation Agent in accordance with the following formula:

(a) If an Extraordinary Dividend Adjustment Event has occurred, but no Dividend Adjustment Event (in accordance with paragraph 3.1.2.1 (Dividend Adjustments) above) has occurred for which the Ex-Dividend Date would fall on the same day, the following formula will be used to calculate the Adjustment Factor in respect of any Extraordinary Dividend:

(b) If an Extraordinary Dividend Adjustment Event and a Dividend Adjustment Event (in accordance with paragraph 3.1.2.1 (Dividend Adjustments) above) has occurred for which the Ex-Dividend Date shall fall on the same day, the following formula will be used to calculate the Adjustment Factor in respect of any Extraordinary Dividend:

where:

“Extraordinary Dividend Amount” means in respect of an Extraordinary Dividend: 100%

“Extraordinary Dividend” means a dividend or a distribution or portion thereof which is determined by the Index Calculation Agent to be an extraordinary dividend relating to such Constituent having regard to general market consensus and will generally include any dividend (in the form of a cash dividend) which is described as “special”, “extra”, “irregular” or a “return of capital”, for which the applicable Ex-Dividend Date falls on any day after the Index Start Date.

“Ex-Dividend Date” means, in respect of a share and an Extraordinary Dividend, the first day on which a purchaser of such share will not be entitled to receive the relevant Extraordinary Dividend Amount, as fixed by the issuer of such share and/or the primary exchange on which such share is traded.

“FX Rate” means, in respect of the notional exchange of one currency to another currency, the applicable WM/Reuters “Closing Spot Rate” as published by The World Markets Company plc in conjunction with Reuters at approximately 4.00 p.m. (London time) on the Ex-Dividend Date or, if such rate is discontinued or unavailable on the relevant day for any reason, such other exchange rate for the relevant currency conversion as the Index Calculation Agent shall determine appropriate by reference to an alternative widely-used and publicly available third party foreign exchange rate service.

3.1.2.4       Rights Issue Adjustment

Following the declaration by the issuer of an Constituent of a Rights Issue (as defined below) (a “Rights Issue Adjustment Event”), the Index Calculation Agent shall calculate the adjustment factor in respect of such Rights Issue on the Ex-Rights Date in accordance with the formula set out below and apply the outcome of the below formula to the product of all Adjustment Factors in accordance with paragraph 3.1 (Total Return) above. If such Ex-Rights Date is not an Index Business Day, the adjustment shall be made on the following Index Business Day.

An Adjustment Factor in respect of a Rights Issue in relation to the Constituent shall be determined by the Index Calculation Agent in accordance with the following formula:

where:

“Ex-Rights Date” means, in respect of a Rights Issue in respect of an Constituent, the first day on which a purchaser of such share would not be entitled to participate in such Rights Issue, as fixed by the issuer of such Constituent and/or the primary exchange on which such Constituent is traded.

3.2 In respect of Constituents 7 and 8

The Index Constituent Level on each Index Business Day will be the relevant Constituent Closing Level on such Index Business Day or, if not published on such day, as published on the first preceding Index Business Day.

(As at the Core Index Start Date.)

Table 1: Constituents and other data

Constituents colour-coded green are contained in the NR Group.

Constituents colour-coded purple are contained in the R Group.

Each of Constituent 1 to Constituent 6 (inclusive) is an Equity Constituent.

For each ETF Share, the Primary Exchange on which the price of such ETF Share is quoted is represented by the relevant Bloomberg ticker, with “UP” specified as the EXCH_CODE (e.g. “XLP UP Equity”).

Where historical data are not available or are not consistent for the relevant UP Bloomberg ticker, either a proxy is used or, where available, the corresponding relevant Bloomberg ticker is used, but with “US” specified as the EXCH_CODE (e.g. “XLP US Equity”).

For back-testing purposes, each time series has been computed as follows:

o       if a date occurs prior to the UP-US Cross-Over Date specified in respect of a Constituent (in which case the UP time series is not considered to be consistent), then “US ETF Total Return Level” data are used in respect of such Constituent; and

o       if a date occurs on or after the UP-US Cross-Over Date specified in respect of a Constituent, then “UP ETF Total Return Level” data are used.

“UP-US Cross-Over Date” shall mean, in respect of a Constituent, the first date from which UP ETF Total Return Level data are used for the purposes of the computation of the corresponding Index Constituent Level, and such date is determined by the Index Administrator in respect of the UP (Primary Exchange) available time series (e.g. “XLB UP Equity”). After this date, the UP time series is considered to be consistent and is directly used in the paragraph 3 (“Determination of Index Constituent Level”). The UP-US Cross-Over Date in respect of each Constituent is specified under the heading “UP-US Cross-Over Date” in the table set out below.
