Dual Directional Barrier Securities Linked to the S&P500 Futures Excess Return 
Index Due November 30, 2028

 ▪ The securities offered by this pricing supplement are unsecured debt      
          securities issued by Citigroup Global Markets Holdings Inc. and guaranteed
          by Citigroup Inc.  Unlike conventional debt securities, the securities    
          do not pay interest and do not repay a fixed amount of principal          
          at maturity. Instead, the securities offer a payment at maturity          
          that may be greater than, equal to or less than the stated principal      
          amount, depending on the performance of the underlying specified below    
          from the initial underlying value to the final underlying value.          


 ▪ The underlying tracks futures contracts on the S&P 500                                       
          (R)                                                                                          
          Index and is expected to underperform the total return performance of the S&P 500            
          (R)                                                                                          
          Index because of an implicit financing cost. See "Summary Risk Factors" for more information.


 ▪ The securities offer modified exposure to the performance of the underlying, with                        
          the opportunity to participate in the potential appreciation of the underlying at                        
          the upside participation rate specified below. If the underlying depreciates, the                        
          securities offer positive participation in the absolute value of that depreciation,                      
          but only                                                                                                 
          so long as the final underlying value is greater than or equal to the final                              
          barrier value specified below.  In exchange for these features, investors                                
          in the securities must be willing to accept exposure to an index that                                    
          is expected to underperform the total return performance of the S&P 500                                  
          (R)                                                                                                      
          Index and forgo (i) positive participation in the absolute value of any depreciation of the underlying if
          the final underlying value is less than the final barrier value and (ii) any dividends with respect to   
          the underlying.  In addition, investors in the securities must be willing to accept downside exposure to 
          any depreciation of the underlying if the final underlying value is less than the final barrier value.   
          If the final underlying value is less than the final barrier value, you                                  
          will lose 1% of the stated principal amount of your securities for                                       
          every 1% by which the final underlying value is less than the initial                                    
          underlying value. You may lose your entire investment in the securities.                                 


 ▪ Investors in the securities must be willing to accept (i) an investment that may have limited or no liquidity and (ii)
          the risk of not receiving any payment due under the securities if we and Citigroup Inc. default on our obligations.   
          All payments on the securities are subject to the credit risk

(1) Citigroup Global Markets HoldingsInc. currently expects that the estimated 
value of the securities on the pricing date will be at least $878.00 per 
security, which willbe less than the issue price. The estimated value of the 
securities is based on CGMI's proprietary pricing models and our internalfunding
 rate. It is not an indication of actual profit to CGMI or other of our 
affiliates, nor is it an indication of the price, if any,at which CGMI or any 
other person may be willing to buy the securities from you at any time after 
issuance. See "Valuation of theSecurities" in this pricing supplement.
(2) CGMI will receive an underwritingfee of up to $41.25 for each security 
sold in this offering. The total underwriting fee and proceeds to issuer in 
the table above giveeffect to the actual total underwriting fee. For more 
information on the distribution of the securities, see "Supplemental Planof 
Distribution" in this pricing supplement. In addition to the underwriting fee, 
CGMI and its affiliates may profit from expectedhedging activity related to 
this offering, even if the value of the securities declines. See "Use of 
Proceeds and Hedging"in the accompanying prospectus.
(3) The per security proceeds to issuerindicated above represent the minimum 
per security proceeds to issuer for any security, assuming the maximum per 
security underwritingfee. As noted above, the underwriting fee is variable.

Concurrent with this offering of the securities,the issuer is offering other 
securities that are similar to the securities but that have economic terms 
that differ from those providedby the securities. The differences in the 
economic terms reflect differences in costs to the issuer in connection with 
the distributionof the securities and such other securities.

Hypothetical Examples

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

The examples below are based on the following hypothetical values anddo not 
reflect the actual initial underlying value or final barrier value.  For the 
actual initial underlying value and finalbarrier value, see the cover page of 
this pricing supplement.  We have used these hypothetical values, rather than 
the actualvalues, to simplify the calculations and aid understanding of how 
the securities work.  However, you should understand thatthe actual payment at 
maturity on the securities will be calculated based on the actual initial 
underlying value and final barrier value,and not the hypothetical values 
indicated below. For ease of analysis, figures below may have been rounded.



Hypothetical initial underlying value: 100.00                                                     
Hypothetical final barrier value:      60.00 (60.00% of the hypothetical initial underlying value)


Example 1-Upside Scenario.
The final underlying value is105, resulting in a 5.00% underlying return.  In 
this example, the final underlying value is
greater than
the initialunderlying value.

Payment at maturity per security = $1,000 + the upside return amount

= $1,000 + ($1,000 x the underlying return x the upsideparticipation rate)

= $1,000 + ($1,000 x 5.00% x 170%)

= $1,000 + $85.00

= $1,085.00

In this scenario, the underlying has appreciated from the initial 
underlyingvalue to the final underlying value, and your total return at 
maturity would equal the underlying return
multiplied by
the upsideparticipation rate.

Example 2-Absolute Return Scenario.
The final underlyingvalue is 95, resulting in a -5% underlying return.  In 
this example, the final underlying value is
less than
the initialunderlying value but
greater than
the final barrier value.

Payment at maturity per security = $1,000 + the absolute return amount

= $1,000 + ($1,000 x the absolute value of the underlying return)

= $1,000 + ($1,000 x |-5.00%|)

= $1,000 + $50.00

= $1,050.00

In this scenario, the underlying has depreciated fromthe initial underlying 
value to the final underlying value, but not below the final barrier value, 
and your total return at maturity wouldequal the absolute value of the 
underlying return.

Example 3-Downside Scenario.
The final underlying valueis 30, resulting in a -70.00% underlying return.  In 
this example, the final underlying value is
less than
the finalbarrier value.

Payment at maturity per security = $1,000 + ($1,000 x the underlyingreturn)

= $1,000 + ($1,000 x -70.00%)

= $1,000 + -$700.00

= $300.00

In this scenario, the underlying has depreciated from the initial 
underlyingvalue to the final underlying value and the final underlying value 
is less than the final barrier value.  As a result, yourtotal return at 
maturity in this scenario would be negative and would reflect 1-to-1 exposure 
to the negative performance of the underlying.

Summary Risk Factors

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

The following is a summary of certain key risk factors for investorsin the 
securities.  You should read this summary together with the more detailed 
description of risks relating to an investmentin the securities contained in 
the section "Risk Factors Relating to the Securities" beginning on page EA-7 
in the accompanyingproduct supplement. You should also carefully read the risk 
factors included in the accompanying prospectus supplement and in the 
documentsincorporated by reference in the accompanying prospectus, including 
Citigroup Inc.'s most recent Annual Report on Form 10-K andany subsequent 
Quarterly Reports on Form 10-Q, which describe risks relating to the business 
of Citigroup Inc. more generally.


 ▪ You may lose a significant portion                               
          or all of your investment.                                       
          Unlike conventional debt securities, the securities do not repaya
          fixed amount of principal at maturity.  Instead, your payment at 
          maturity will depend on the performance of the underlying.If the 
          final underlying value is less than the final barrier value, you 
          will lose 1% of the stated principal amount of the securitiesfor 
          every 1% by which the final underlying value is less than the    
          initial underlying value. There is no minimum payment at maturity
          onthe securities, and you may lose up to all of your investment. 



 ▪ Your potential for positive return from                                       
          depreciation of the underlying is limited.                                    
          Thereturn potential of the securities in the event that the final underlying  
          value is less than the initial underlying value is limited bythe final barrier
          value. Any decline in the final underlying value below the final barrier value
          will result in a loss, rather than apositive return, on the securities.       



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



 ▪ You will not receive dividends or have any                                                                    
          other rights with respect to the underlying.                                                                  
          You will not receive anydividends with respect to the underlying.  This lost dividend yield may be significant
          over the term of the securities.  Thepayment scenarios described in this pricing supplement do not            
          show any effect of lost dividend yield over the term of the securities.  Inaddition, you will not have        
          voting rights or any other rights with respect to the underlying or the stocks included in the underlying.    



 ▪ Your payment at maturity                                                 
          depends on the closing                                                   
          value of the underlying on a single day.                                 
          Because your payment atmaturity depends on the closing value of the      
          underlying solely on the valuation date, you are subject to the risk that
          the closing valueof the underlying on that day may be lower, and         
          possibly significantly lower, than on one or more other dates during the 
          term of the securities.  Ifyou had invested in another instrument linked 
          to the underlying that you could sell for full value at a time selected  
          by you, or if thepayment at maturity were based on an average of closing 
          values of the underlying, you might have achieved better returns.        



 ▪ The securities are subject to the credit risk of Citigroup                             
          Global Markets Holdings Inc. and Citigroup Inc.                                        
          If we default onour obligations under the securities and Citigroup Inc. defaults on its
          guarantee obligations, you may not receive anything owed to youunder the securities.   



 ▪ The securities will not be listed                                
          on any securities exchange                                       
          and you may not be able to                                       
          sell them prior to maturity.                                     
          The securitieswill not be listed on any securities exchange.     
          Therefore, there may be little or no secondary market for the    
          securities. CGMI currentlyintends to make a secondary market in  
          relation to the securities and to provide an indicative bid price
          for the securities on a dailybasis. Any indicative bid price for 
          the securities provided by CGMI will be determined in CGMI's     
          sole discretion, taking into accountprevailing market conditions 
          and other relevant factors, and will not be a representation     
          by CGMI that the securities can be sold at thatprice, or at all. 
          CGMI may suspend or terminate making a market and providing      
          indicative bid prices without notice, at any time and forany     
          reason. If CGMI suspends or terminates making a market, there may
          be no secondary market at all for the securities because it is   
          likelythat CGMI will be the only broker-dealer that is willing   
          to buy your securities prior to maturity. Accordingly, an        
          investor must be preparedto hold the securities until maturity.  



 ▪ The estimated value of the securities on the                       
          pricing date, based on CGMI's proprietary                          
          pricing models and our internal                                    
          fundingrate, is less than the issue price.                         
          The difference is attributable to certain costs associated with    
          selling, structuringand hedging the securities that are included   
          in the issue price. These costs include (i) any selling concessions
          or other fees paid inconnection with the offering of the           
          securities, (ii) hedging and other costs incurred by us and our    
          affiliates in connection with theoffering of the securities and    
          (iii) the expected profit (which may be more or less than actual   
          profit) to CGMI or other of our affiliatesin connection with       
          hedging our obligations under the securities. These costs adversely
          affect the economic terms of the securities because,if they were   
          lower, the economic terms of the securities would be more favorable
          to you. The economic terms of the securities are alsolikely        
          to be adversely affected by the use of our internal funding rate,  
          rather than our secondary market rate, to price the securities.See 
          "The estimated value of the securities would be lower if it        
          were calculated based on our secondary market rate" below.

 ▪ The estimated value of the                                             
          securities was determined for                                          
          us by our affiliate using                                              
          proprietary pricing models.                                            
          CGMI derivedthe estimated value disclosed on the cover page of this    
          pricing supplement from its proprietary pricing models. In doing so,   
          it may havemade discretionary judgments about the inputs to its models,
          such as the volatility of the closing value of the underlying,         
          the dividendyield on the underlying and interest rates. CGMI's views   
          on these inputs may differ from your or others' views, and as          
          anunderwriter in this offering, CGMI's interests may conflict with     
          yours. Both the models and the inputs to the models may prove          
          tobe wrong and therefore not an accurate reflection of the value       
          of the securities. Moreover, the estimated value of the securities     
          setforth on the cover page of this pricing supplement may differ       
          from the value that we or our affiliates may determine for the         
          securitiesfor other purposes, including for accounting purposes. You   
          should not invest in the securities because of the estimated value     
          of the securities.Instead, you should be willing to hold the           
          securities to maturity irrespective of the initial estimated value.    



 ▪ The estimated value of the                                                                                                
          securities would be lower if                                                                                              
          itwere calculated based on                                                                                                
          our secondary market rate.                                                                                                
          The estimated value of the securities included in this pricing supplementis calculated based on our internal funding rate,
          which is the rate at which we are willing to borrow funds through the issuance of thesecurities. Our internal funding     
          rate is generally lower than our secondary market rate, which is the rate that CGMI will use in determiningthe value      
          of the securities for purposes of any purchases of the securities from you in the secondary market. If the estimated      
          valueincluded in this pricing supplement were based on our secondary market rate, rather than our internal funding        
          rate, it would likely belower. We determine our internal funding rate based on factors such as the costs associated       
          with the securities, which are generallyhigher than the costs associated with conventional debt securities, and our       
          liquidity needs and preferences. Our internal funding rateis not an interest rate that is payable on the securities.      


Because there is not an active market for traded instruments referencing our 
outstanding debt obligations, CGMI determines our secondarymarket rate based 
on the market price of traded instruments referencing the debt obligations of 
Citigroup Inc., our parent company andthe guarantor of all payments due on the 
securities, but subject to adjustments that CGMI makes in its sole discretion. 
 Asa result, our secondary market rate is not a market-determined measure of 
our creditworthiness, but rather reflects the market'sperception of our parent 
company's creditworthiness as adjusted for discretionary factors such as 
CGMI's preferences withrespect to purchasing the securities prior to maturity.



 ▪ The estimated value of                                                                                             
          the securities is not an                                                                                           
          indication of the price,                                                                                           
          if any, at which CGMI                                                                                              
          or any other person may be willingto buy the                                                                       
          securities from you in the secondary market.                                                                       
          Any such secondary market price will fluctuate over the term ofthe securities based on the market and other factors
          described in the next risk factor. Moreover, unlike the estimated value includedin this pricing supplement,        
          any value of the securities determined for purposes of a secondary market transaction will be based on             
          oursecondary market rate, which will likely result in a lower value for the securities than if our internal        
          funding rate were used. In addition,any secondary market price for the securities will be reduced by a bid-ask     
          spread, which may vary depending on the aggregate stated principalamount of the securities to be purchased         
          in the secondary market transaction, and the expected cost of unwinding related hedging transactions.As a          
          result, it is likely that any secondary market price for the securities will be less than the issue price.         



 ▪ The value of the securities                                                                                    
          prior to maturity will                                                                                         
          fluctuate based on many                                                                                        
          unpredictable factors.                                                                                         
          The value of your securitiesprior to maturity will fluctuate based on the closing value of the underlying,     
          the volatility of the closing value of the underlying,the dividend yield on the underlying, interest rates     
          generally, the time remaining to maturity and our and Citigroup Inc.'s creditworthiness,as reflected in our    
          secondary market rate, among other factors described under "Risk Factors Relating to the Securities-RiskFactors
          Relating to All Securities-The value of your securities prior to maturity will fluctuate based on many         
          unpredictable factors"in the accompanying product supplement. Changes in the closing value of the underlying   
          may not result in a comparable change in the valueof your securities. You should understand that the           
          value of your securities at any time prior to maturity may be significantly less thanthe issue price.          



 ▪ Immediately following issuance, any secondary market bid price provided by CGMI, and the value that will be indicated
          on any brokerageaccount statements prepared by CGMI or its affiliates, will reflect a temporary upward adjustment.   
          The amount of this temporaryupward adjustment will steadily decline to zero over the                                 
          temporary adjustment period.  See "Valuation of the Securities"in this pricing supplement.                           



 ▪ The underlying is expected to underperform

          expected to be reduced                                             
          by an implicit financing

          this cost will adversely                                           
          affect the performanceof the securities.

          it is expectedto reflect not only the                              
          performance of its reference

          Index), but also the implicit cost of a financedposition in        
          that reference index. The cost of this financed position will      
          adversely affect the value of the underlying. Any increase         
          inmarket interest rates will be expected to further increase this  
          implicit financing cost and will increase the negative effect      
          on the performanceof the underlying. Because of this implicit      
          financing cost, the S&P 500 Futures Excess Return Index is expected
          to underperform thetotal return performance of the S&P 500

          Consequently, significant aspects of the tax treatment of the securities are uncertain, and     
          the IRSor a court might not agree with the treatment of the securities as prepaid forward       
          contracts.  If the IRS were successful inasserting an alternative treatment of the securities,  
          the tax consequences of the ownership and disposition of the securities might bematerially

United States FederalTax Considerations

You should read carefully the discussion under "United StatesFederal Tax 
Considerations" and "Risk Factors Relating to the Securities" in the 
accompanying product supplement and"Summary Risk Factors" in this pricing 
supplement.

In the opinion of our counsel, Davis Polk & Wardwell LLP, a securityshould be 
treated as a prepaid forward contract for U.S. federal income tax purposes.  
By purchasing a security, you agree (inthe absence of an administrative 
determination or judicial ruling to the contrary) to this treatment.  There is 
uncertaintyregarding this treatment, and the IRS or a court might not agree 
with it. Moreover, our counsel's opinion is based on market conditionsas of 
the date of this preliminary pricing supplement and is subject to confirmation 
on the pricing date.

Assuming this treatment of the securities is respected and subject tothe 
discussion in "United States Federal Tax Considerations" in the accompanying 
product supplement, the following U.S. federalincome tax consequences should 
result under current law:


 . You should not recognize taxable income over the term of the securities
   prior to maturity, other than pursuant to a sale or exchange.          



 . Upon a sale or exchange of a security (including retirement at maturity), you  
   should recognize capital gain or loss equal to the differencebetween the amount
   realized and your tax basis in the security.  Such gain or loss should be      
   long-term capital gain or lossif you held the security for more than one year. 


We do not plan to request a ruling from the IRS regarding the treatmentof the 
securities. An alternative characterization of the securities could materially 
and adversely affect the tax consequences of ownershipand disposition of the 
securities, including the timing and character of income recognized. In 
addition, the U.S. Treasury Departmentand the IRS have requested comments on 
various issues regarding the U.S. federal income tax treatment of "prepaid 
forward contracts"and similar financial instruments and have indicated that 
such transactions may be the subject of future regulations or other 
guidance.Furthermore, members of Congress have proposed legislative changes to 
the tax treatment of derivative contracts. Any legislation, Treasuryregulations 
or other guidance promulgated after consideration of these issues could 
materially and adversely affect the tax consequencesof an investment in the 
securities, possibly with retroactive effect. You should consult your tax 
adviser regarding possible alternativetax treatments of the securities and 
potential changes in applicable law.

Non-U.S. Holders
. Subject to the discussions below and in "UnitedStates Federal Tax 
Considerations" in the accompanying product supplement, if you are a Non-U.S. 
Holder (as defined in the accompanyingproduct supplement) of the securities, 
you generally should not be subject to U.S. federal withholding or income tax 
in respect of anyamount paid to you with respect to the securities, provided 
that (i) income in respect of the securities is not effectively connectedwith 
your conduct of a trade or business in the United States, and (ii) you comply 
with the applicable certification requirements.

As discussed under "United States Federal Tax Considerations-TaxConsequences 
to Non-U.S. Holders" in the accompanying product supplement, Section 871(m) of 
the Code and Treasury regulations promulgatedthereunder ("Section 871(m)") 
generally impose a 30% withholding tax on dividend equivalents paid or deemed 
paid to Non-U.S.Holders with respect to certain financial instruments linked 
to U.S. equities ("U.S. Underlying Equities") or indices thatinclude U.S. 
Underlying Equities.  Section 871(m) generally applies to instruments that 
substantially replicate the economicperformance of one or more U.S. Underlying 
Equities, as determined based on tests set forth in the applicable Treasury 
regulations.  However,the regulations, as modified by an IRS notice, exempt 
financial instruments issued prior to January 1, 2025 that do not have a 
"delta"of one.  Based on the terms of the securities and representations 
provided by us as of the date of this preliminary pricingsupplement, our 
counsel is of the opinion that the securities should not be treated as 
transactions that have a "delta" ofone within the meaning of the regulations 
with respect to any U.S. Underlying Equity and, therefore, should not be 
subject to withholdingtax under Section 871(m).  However, the final 
determination regarding the treatment of the securities under Section 871(m) 
willbe made as of the pricing date for the securities, and it is possible that 
the securities will be subject to withholding tax under Section871(m) based on 
the circumstances as of that date.

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


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

You should read the section entitled "United States FederalTax Considerations" 
in the accompanying product supplement.  The preceding discussion, when read 
in combination with thatsection, constitutes the full opinion of Davis Polk & 
Wardwell LLP regarding the material U.S. federal tax consequences of owningand 
disposing of the securities.

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

Supplemental Planof Distribution

CGMI, an affiliate of Citigroup GlobalMarkets Holdings Inc. and the 
underwriter of the sale of the securities, is acting as principal and will 
receive an underwriting fee ofup to $41.25 for each security sold in this 
offering. The actual underwriting fee will be equal to the selling concession 
provided toselected dealers, as described in this paragraph. From this 
underwriting fee, CGMI will pay selected dealers not affiliated with CGMIa 
variable selling concession of up to $41.25 for each security they sell.

See "Plan of Distribution; Conflictsof Interest" in the accompanying product 
supplement and "Plan of Distribution" in each of the accompanying 
prospectussupplement and prospectus for additional information.

Valuation of the Securities

CGMI calculated the estimatedvalue of the securities set forth on the cover 
page of this pricing supplement based on proprietary pricing models. CGMI's 
proprietarypricing models generated an estimated value for the securities by 
estimating the value of a hypothetical package of financial instrumentsthat 
would replicate the payout on the securities, which consists of a fixed-income 
bond (the "bond component") and one ormore derivative instruments underlying 
the economic terms of the securities (the "derivative component"). CGMI 
calculatedthe estimated value of the bond component using a discount rate 
based on our internal funding rate. CGMI calculated the estimated valueof the 
derivative component based on a proprietary derivative-pricing model, which 
generated a theoretical price for the instruments thatconstitute the 
derivative component based on various inputs, including the factors described 
under "Summary Risk Factors-Thevalue of the securities prior to maturity will 
fluctuate based on many unpredictable factors" in this pricing supplement, but 
notincluding our or Citigroup Inc.'s creditworthiness. These inputs may be 
market-observable or may be based on assumptions made byCGMI in its 
discretionary judgment.

The estimated value of the securitiesis a function of the terms of the 
securities and the inputs to CGMI's proprietary pricing models.  As of the 
date of thispreliminary pricing supplement, it is uncertain what the estimated 
value of the securities will be on the pricing date because it is 
uncertainwhat the values of the inputs to CGMI's proprietary pricing models 
will be on the pricing date.

For a period of approximatelyfour months following issuance of the securities, 
the price, if any, at which CGMI would be willing to buy the securities from 
investors,and the value that will be indicated for the securities on any 
brokerage account statements prepared by CGMI or its affiliates (whichvalue 
CGMI may also publish through one or more financial information vendors), will 
reflect a temporary upward adjustment from the priceor value that would 
otherwise be determined. This temporary upward adjustment represents a portion 
of the hedging profit expected to berealized by CGMI or its affiliates over 
the term of the securities. The amount of this temporary upward adjustment 
will decline to zeroon a straight-line basis over the four-month temporary 
adjustment period. However, CGMI is not obligated to buy the securities from 
investorsat any time.  See "Summary Risk Factors-The securities will not be 
listed on any securities exchange and you maynot be able to sell them prior to 
maturity."

Index Calculation

The S&P 500 Futures Excess Return Index tracks the performance ofa 
hypothetical position, rolled quarterly, in the nearest-to-expiration E-mini 
S&P 500 futures contract. Constructed from E-mini S&P500 futures contracts, 
the S&P 500 Futures Excess Return Index includes provisions for the 
replacement of the current E-mini S&P500 futures contract in the S&P 500 
Futures Excess Return Index as such futures contract approaches expiration 
(also referred to as"rolling"). This replacement occurs over a one-day rolling 
period every quarter, which is five days prior to the last tradedate of the 
futures contract.

The S&P 500 Futures Excess Return Index is calculated from the pricechange of 
the underlying E-mini S&P 500 futures contract. On any trading date,
t
, the value of the S&P 500 Futures ExcessReturn Index is calculated as follows:

no market disruptions exist.

The S&P 500 Futures Excess Return Index is an excess return index,which in 
this context means that its performance will be based solely on changes in the 
settlement price of its underlying futures contract.An excess return index is 
distinct from a total return index, which, in addition to changes in the 
settlement price of the underlyingfutures contract, would reflect interest on 
a hypothetical cash position collateralizing that futures contract.

E-mini S&P 500 futures contracts

E-mini S&P 500 futures contracts were introduced in 1997 and aretraded on the 
Chicago Mercantile Exchange under the ticker symbol "ES." The Chicago 
Mercantile Exchange trades E-mini S&P500 futures contracts with expiration 
dates in March, June, September and December of each year.

E-mini S&P 500 futures contracts differ from the futures contractsdescribed 
below under "-Futures Contracts Generally" in that E-mini S&P 500 futures 
contracts are cash settled only,meaning that the 500 stocks composing the S&P 
500 Index are not actually delivered upon settlement of the futures contract. 
Therefore,the E-mini S&P 500 futures contracts are not contracts to actually 
buy and sell the stocks in the S&P 500 Index. In all otherrelevant respects, 
however - including daily "mark to market" and realization of gains or losses 
based on the differencebetween the current settlement price and the initial 
futures price - the E-mini S&P 500 futures contracts are similar to 
thosedescribed below under "-Futures Contracts Generally."

Futures Contracts Generally

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

For example, suppose that a futures contract entered into in Januarycalls for 
the purchaser to buy the underlying asset in April at a price of $1,000. If 
the underlying asset is worth $1,200 in April, thenupon settlement of the 
futures contract in April the purchaser will buy for $1,000 an underlying 
asset worth $1,200, achieving a $200gain. Conversely, if the underlying asset 
is worth $800 in April, then upon settlement of the futures contract in April 
the purchaserwill 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 differentfrom 
the gain or loss that could have been achieved by the direct purchase of the 
underlying asset in January and the sale of that underlyingasset in April. 
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 exposureto 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 priceof the 
underlying asset and the futures price. A "futures price" is the price at 
which market participants may agree todayto buy or sell the underlying asset 
in the future, and the "spot price" is the current price of the underlying 
asset for immediatedelivery. The futures price is determined by market supply 
and demand and is independent of the spot price, but it is nevertheless 
generallyexpected 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 sothere would 
be an opportunity for traders to make sure profits, known as "arbitrage"). For 
example, if January's futuresprice is $1,000, January's spot price may be 
$975. If the underlying asset is worth $1,200 in April, the gain on the 
futures contractwould be $200 ($1,200 minus $1,000), while the gain on a 
direct investment made at the January spot price would have been $225 
($1,200minus $975). The lower return on the futures contract as compared to 
the direct investment reflects this implicit financing cost. Becauseof this 
financing cost, it is possible for a purchaser to incur a loss on a futures 
contract even if the spot price of the underlyingasset increases over the term 
of the futures contract. The amount of this financing cost is expected to 
increase as general market interestrates increase.

Futures contracts are standardized instruments that are traded on anexchange. 
On each trading day, the exchange determines a settlement price (which may 
also be referred to as a closing price) for thatfutures contract based on the 
futures prices at which market participants entered into that futures contract 
on that day. Open positionsin futures contracts are "marked to market" and 
margin is required to be posted on each trading day. This means that, on 
eachtrading day, the current settlement price for a futures contract is 
compared to the futures price at which the purchaser entered intothat futures 
contract. If the current settlement price has decreased from the initial 
futures price, then the purchaser will be requiredto 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 realizedon 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 contractmust be 
rolled into another if there is a desire to maintain a continuous position in 
futures contracts on (rather than take deliveryof) a particular underlying 
asset. This is typically achieved by closing out the position in the existing 
futures contract as its expirationdate 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.
