Citigroup Global Markets Holdings Inc. 2 Traditional Bonds A bond is a loan that an investor makes to the issuer for a specified amount of time, e. g. 5 years. In return for the use of these proceeds, and to compensate the investor for the risk that the issuer will not return principal, traditional bonds pay periodic fixed coupons to the holder of the bond. Lends $1,000 principal Structured Investments A structured investment is also a loan that an investor makes to the issuer for a specified amount of time, e. g. 5 years. In contrast to traditional bonds, rather than receiving fixed income, structured investments offer a return that is contingent on the performance of an underlying index or asset, e. g. the S&P 500® Index. Lends $1,000 principal Some structured investments provide for the repayment of the full amount of principal at maturity, subject to the issuer's credit risk. Others provide for a payment at maturity that may be less than principal (and possibly zero) depending on the performance of the underlying index or asset. What Are Structured Investments?

Citigroup Global Markets Holdings Inc. 3 Access Structured Investments can be used to gain exposure to hard to reach underlyings, such as: • International equities • Commodities • Rates • Currencies Structured Investments can also be used to gain exposure to algorithmic trading strategies, e. g. proprietary indices. T a c ti c a l I n v e s t m ent Structured Investments can be tailored to fit a specific market view. For example a moderately bullish view on emerging markets with some risk appetite can translate to a structured investment linked to emerging markets equities, with increased participation on the upside subject to a maximum return, coupled with some protection on the downside . Portfolio Allocation When used in a portfolio, Structured Investments can potentially provide additional benefits such as: • Additional growth potential • Additional protection • Additional yield potential • Diversification of assets and risk/return profiles → potentially leading to greater risk adjusted returns Different structured investments offer different risk/return tradeoffs, and not all offer the potential benefits described above. You should consider the potential benefits of structured investments together with the risks associated with structured investments, as described on the next page and in the applicable pricing supplement.

Citigroup Global Markets Holdings Inc. 4 Potential for Loss The terms of certain investments provide that the full principal amount is due at maturity, subject to the issuer's credit risk. However, if an investor sells such investment prior to maturity, the investor may receive an amount less than his/her original investment. The terms of certain investments provide that the payment due at maturity could be significantly less than the full principal amount and, for certain investments, could be zero. In these cases, an investor may receive an amount significantly less than his/her original investment and may receive nothing at maturity of the investment. No or Contingent Interest Certain investments do not pay interest or any other amounts prior to maturity. Others may pay interest that is contingent on the performance of an underlying asset or index. In the latter case, if the applicable condition to payment of interest is not met, these investments will not pay interest on one or more, or any, interest payment dates. Appreciation May Be Limited Depending on the investment, an investor's appreciation may be limited by a maximum amount payable, and therefore may be less than the performance of the underlying asset or index. Other investments do not offer any participation in any appreciation of the underlying asset or index. Potential for Lower Comparable Yield The effective yield on any investment may be less than that which would be payable on a conventional fixed - rate debt security of the same issuer with comparable maturity . No Dividends Holders of structured investments will not receive the dividends that would be paid on a direct investment in the underlying index or asset. Issuer Credit Risk All payments on structured investments are dependent on the issuer's or guarantor's ability to pay all amounts due on these investments, including any principal due at maturity, and therefore investors are subject to the credit risk of the issuer and guarantor . The United States Federal Tax Consequences of Owning Structured Investments May Be Uncertain There is no direct legal authority regarding the proper U.S. federal tax treatment of certain Structured Investments, and we do not plan to request a ruling from the Internal Revenue Service (the "IRS"). Consequently, significant aspects of the tax treatment of those investments are uncertain. Investors should refer to the applicable offering document(s) for each Structured Investment regarding its U.S. federal tax treatment. However, no assurance can be given that the IRS will agree with the treatment described within the offering document(s) for a particular Structured Investment. Citigroup Inc., its affiliates, and employees do not provide tax or legal advice. Investors should consult with their own professional advisor(s) on such matters before investing in any Structured Investment. Secondary Market Structured investments generally will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the securities and an investor may not be able to sell them prior to maturity. Resale Value of a Structured Investment May be Lower than the Initial Investment The value of structured investments prior to maturity will fluctuate based on the price and volatility of the underlying asset or index and a number of other factors, including dividend yield on the underlying, interest rates generally, the time remaining to maturity and the issuer's creditworthiness. The value of the securities at any time prior to maturity may be significantly less than the issue price. Conflicts of Interest The issuer and its affiliates may have a number of conflicts of interest with investors in the securities as a result of their hedging, trading and other business activities. These risks are not intended to be an exhaustive list of the risks associated with a particular structured investment offering. Before you invest in any structured investment you should thoroughly review the particular investment's pricing supplement and any applicable product or index supplement together with the prospectus supplement and prospectus for a comprehensive description of the risks and considerations associated with the particular investment. Selected Risks and Considerations of Structured Investments

![](image_005.jpg)

Citigroup Global Markets Holdings Inc. 5 The issuer of a structured investment seeks to provide the investor with exposure to an underlying index or asset, without the issuer itself having exposure to the underlying. The issuer achieves this by hedging its obligations under the structured investment, so that any payment on the structured investment that is linked to the underlying will be offset by the issuer's hedge. From the issuer's perspective, after hedging its obligations, the issuer may view a structured investment as though it had simply issued a zero coupon bond at a discount to its principal amount. Although the investor in the structured investment pays the full principal amount at issuance, the issuer uses a portion of that amount to pay the cost of hedging its obligations and other costs of the offering. The amount available to the issuer after paying these costs is at a discount to the principal amount. A zero coupon bond is a non - interest paying bond issued at a discount, where the "interest" return is entirely in the difference between the discounted amount paid for the bond and the principal received at maturity. This is in contrast to a traditional bond where interest is paid along the way. Traditional Bond Zero Coupon Bond The size of the coupon payments on a traditional bond, and equally the size of the discount on a zero coupon bond, represents the borrowing cost to the issuer of the bond and is a reflection of the prevailing interest rate environment and the creditworthiness of the issuer, among other factors. Higher interest rates and lower credit generally correspond to larger coupons or discounts, although the amount of borrowing cost that the issuer of a structured investment is willing to pay is determined by the issuer in its discretion and is generally lower than it would pay on a traditional bond. Interest rates and the credit of the issuer affect the amount of potential return offered by a structured investment because they affect the size of the discount on the hypothetical zero coupon bond that the issuer may view itself to have issued, which in turn determines how much of the offering proceeds are available to pay the cost of hedging and the other costs of the offering. The amount available to pay the cost of hedging directly affects the participation or other terms linked to the underlying that the issuer may offer under the structured investment. For example, for a market - linked note tied to the S&P 500® Index, where an investor receives principal at maturity plus any positive return of the index, this can be thought of as a zero coupon bond plus a financial contract on the S&P 500® Index which pays the greater of any positive return and 0% (a "call option"). Although it is not necessary to understand these individual pieces that go into the creation of a structured investment, it can be helpful for those interested in understanding how the economics are determined of any structured investment and why they are affected by interest rates and the creditworthiness of the issuer .

Citigroup Global Markets Holdings Inc. 6 Traditional asset allocation allows investors to choose between (a) Bonds, which are generally relatively low risk and low return and (b) Equities, which are generally relatively higher risk with higher return potential. The vast majority of structured investments target a risk - return profile between that of bonds and equities. "Equity - like" investments with added protection against downturns "Bond - like" investments with added risk to achieve potentially higher returns Structured Investments and Risk - Return B onds Equities Ca s h Market Linked S e c ur iti es Income S e c ur iti es Growth S e c ur iti es Risk / Standard Deviation Growth Securities Growth Securities are generally the most "equity like" structured investments. They typically offer upside participation in the underlying it is linked to (excluding dividends), sometimes limited by a maximum return, with downside exposure subject to some partial or contingent protection. Examples include Buffer Securities, Upturn Securities and Barrier Securities Income Securities Income Securities are generally a bit more in between bond and equity in their style. Typically this type of security will offer some periodic coupon potential, which is generally higher than anything achievable in the traditional debt market, but with the tradeoff of having equity exposure as a downside risk. The coupon itself may also be contingent. Examples include ELKS and Autocallable Contingent Coupon Securities Market Linked Securities Market Linked Securities are generally the most "bond - like". These investments generally protect an investor's full principal at maturity, subject to the credit risk of the issuer, with some market participation on the upside. Despite being comparable to a bond, investors are generally forgoing interest to achieve market returns, and thus are generally still riskier than a traditional debt product of the same credit quality.

Citigroup Global Markets Holdings Inc. 7 Structured investments are valuable tools for portfolio diversification and for managing risk within the portfolio. However, not all structured investments will change a portfolio in the same way and the same structured investment can change the same portfolio in different ways, depending on the allocation. Hypothetical Portfolio Allocation Neither allocation is meant to suggest an ideal allocation, but rather illustrate how structured investments can be used to tailor a portfolio to an investor's needs. Both scenarios offer potentially enhanced risk adjusted returns, subject to the trade - offs described above.

Citigroup Global Markets Holdings Inc. 8 Picking a target allocation is often tied to an investor's risk tolerance, with risky assets getting a higher allocation with higher risk tolerance. However, a given investor's desired allocation may not be static and may be different depending on the market environment. Algorithmic indices can be tools for dynamic portfolio allocation, attempting to give investors different notional exposures in different market environments. Two of Citi's flagship indices are the Citi Dynamic Asset Selector and Citi Radar Indices Citi Dynamic Asset Selector is designed to be an easy to understand and simple to implement strategy. The index uses market signals to determine a market trend and how stable that trend is. Then it allocates accordingly between S&P 500 Index Futures and S&P 10 Year Treasury Futures. The index also includes a hypothetical cash allocation in an attempt to maintain a specified target volatility. Citi Radar 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. Thus it rotates between certain economic sector ETFs and Treasury Futures depending on the trend of the interest rate environment. It determines the allocation between equity ETFs and Treasury Futures, and may include a hypothetical cash allocation, in a manner designed to maintain a specified target volatility. Each of these indices has features that limits the potential equity exposure, and as a result each index is likely to have significant Treasury Futures or hypothetical cash exposure even in equity bull markets. Each index is subject to the risk that it will fail to accurately measure the relevant market trend or that the assumed relationship will fail to exist between the observed trend and the future performance of the index constituents. Each index offers only hypothetical exposure to its constituent assets; no investor has any ownership interest in the constituent assets. An investor has recourse only to the credit of the issuer. Each index is subject to an implicit financing cost, as described more fully in the offering documents for any structured investment linked to one of these indices.
