Key Terms of the Notes:


Reference Asset:	The S&P 500^® Futures Excess Return Index (ticker symbol "SPXFP") . See "The Reference Asset" below for additional information. The Reference Asset measures the performance of a futures contract and not the performance of equity securities. Specifically, the Reference Asset measures the performance of the nearest maturing quarterly E-mini S&P 500^® futures contract trading on the Chicago Mercantile Exchange (the "CME"), not the performance of the S&P 500^® Index (the "Underlying Index"), to which that futures contract is related.
Payment at Maturity:	If the Final Level of the Reference Asset is greater than or equal to its Initial Level, then the amount that investors will receive at maturity for each $1,000 in principal amount of the notes will equal: $1,000 + ($1,000 x Percentage Change of the Reference Asset x Upside Leverage Factor) If the Final Level of the Reference Asset is less than its Initial Level, but is not less than its Barrier Level, then investors will, for each $1,000 in principal amount of the notes, receive the principal amount of $1,000 and no additional return. If the Final Level of the Reference Asset is less than its Barrier Level, then the amount that investors will receive at maturity for each $1,000 in principal amount of the notes will equal: $1,000 + ($1,000 x Percentage Change of the Reference Asset) In this case, investors will lose 1% of their principal for each 1% that the Final Level of the Reference Asset declines from its Initial Level. You may lose all of the principal amount of your notes.
Upside Leverage Factor:	178.50%
Percentage Change:	The quotient, expressed as a percentage, of the following formula: (Final Level - Initial Level ) Initial Level
Initial Level:2	The closing level of the Reference Asset on the Pricing Date.
Barrier Level:2	70.00% of the Initial Level.
Final Level:	The closing level of the Reference Asset on the Valuation Date.
Pricing Date:1	September 11, 2026
Settlement Date:1	September 16, 2026
Valuation Date:1	September 12, 2029

1 Expected and subject to the occurrence of a market disruption event, as described in the accompanying product supplement. If we make any change to the expected Pricing Date and Settlement Date, the Valuation Date and Maturity Date will be changed so that the stated term of the notes remains approximately the same.

2As determined by the calculation agent and subject to adjustment in certain circumstances. See "General Terms of the Notes - Adjustments to a Reference Asset that Is an Index" in the product supplement for additional information.

Selected Risk Considerations

An investment in the notes involves significant risks. Investing in the notes is not equivalent to investing directly in the Reference Asset. These risks are explained in more detail in the “Additional Risk Factors Relating to the Notes” section of the product supplement.

Risks Related to the Structure or Features of the Notes

●Your investment in the notes may result in a loss. — The notes do not guarantee any return of principal. If the Final Level is less than its Barrier Level, you will lose 1% of the principal amount for each 1% that the Final Level is less than the Initial Level. In such a case, you will receive at maturity a cash payment that is less than the principal amount of the notes and may be zero. Accordingly, you could lose your entire investment in the notes.

●Your return on the notes may be lower than the return on a conventional debt security of comparable maturity. — The return that you will receive on your notes, which could be negative, may be less than the return you could earn on other investments. The notes do not provide for interest payments and the payment you receive at maturity, if any, may be less than the principal amount of the notes. Even if your return on the notes is positive, your return may be less than the return you would earn if you bought a conventional senior interest bearing debt security of ours with the same maturity or if you invested directly in the Reference Asset. Your investment may not reflect the full opportunity cost to you when you take into account factors that affect the time value of money.

Risks Related to the Reference Asset

●The notes are linked to the performance of an index comprised of an equity futures contract, which is different from linking to the performance of the Underlying Index. — The performance of the Reference Asset will be related to the performance of an equity futures contract, and not to the performance of the Underlying Index. On a given day, a “futures price” is the price at which market participants may agree to buy or sell the asset underlying a futures contract in the future, and the “spot price” is the current price of such underlying asset for immediate delivery. A variety of factors can lead to a disparity between the price of a futures contract at a given point in time and the spot price of its underlying asset, such as the expected dividend yields of any stocks that comprise such underlying asset, the implicit financing cost associated with the futures contract and market expectations related to the future price of the futures contract’s underlying asset. Purchasing an equity futures contract is similar to borrowing money to buy the underlying asset of such futures contract, because it enables an investor to gain exposure to such underlying asset without having to pay the full cost of such exposure up front, and therefore entails a financing cost. As a result, the Reference Asset is expected to reflect not only the performance of the Underlying Index, but also the implicit financing cost in the E-mini S&P 500 futures contract, among other factors. This implicit financing cost will adversely affect the level of the Reference Asset. Any increase in market interest rates will be expected to further increase this implicit financing cost and will have an adverse effect on the level of the Reference Asset and, therefore, the value of and return on the notes. The price movement of a futures contract is typically correlated with the movements of the price of its underlying asset, but the correlation is generally imperfect, and price movements in the spot market may not be reflected in the futures market (and vice versa). Accordingly, the notes may underperform a similar investment that more directly reflects the return on the Underlying Index.

●Negative roll yields will adversely affect the level of the Reference Asset over time and therefore the payment at maturity. — The Reference Asset is linked to the E-mini S&P 500 futures contract rather than the Underlying Index. Futures contracts normally specify a certain date for cash settlement of a financial future (such as a futures contract on a securities index) or delivery of the underlying physical commodity for a deliverable future. As the exchange-traded futures contract that comprises the Reference Asset approaches expiration, it is replaced by a similar contract that has a later expiration. Thus, for example, a futures contract purchased and held in September may specify a December expiration. As time passes, the contract expiring in December may be replaced by a contract for delivery in March. This process is referred to as “rolling. As a futures contract approaches expiration, its value will generally approach the spot price of its underlying asset because by expiration it will closely represent a contract to buy or sell such underlying asset for immediate delivery. If the market for a futures contract is in “contango,” where the price of the futures contract with a later expiration date during a rolling period is higher than the spot price of its underlying asset, then the value of such futures contract would tend to decline over time (assuming the spot price and other relevant factors remain unchanged), because the higher futures price would decline as it approaches the lower spot price by expiration. This negative effect on the futures price is referred to as a negative “carry” or “roll yield” and is realized over the term of such contract. A negative roll yield will adversely affect the level of the Reference Asset over time and therefore the Payment at Maturity. Because of the potential effects of negative roll yields, it is possible for the level of the Reference Asset to decrease significantly over time, even when the level of the Underlying Index is stable or increasing.

●The Reference Asset is an excess return index, not a total return index — The Reference Asset is an excess return index, not a total return index. An "excess return" index reflects the "price yield" generated by a change in the price of the futures contract comprising the index and the "roll yield" that is generated when the first expiring futures contract is rolled into the second expiring futures contract, but it does not include interest earned on collateral that a hypothetical investor must provide to secure its performance under the futures contract. By contrast, a “total return” index, reflects interest earned on a hypothetical fully collateralized contract position, in addition to the price yield and the roll yield.

●The futures contract comprising the Reference Asset is linked to a price return index — The notes are linked to the Reference Asset, which is comprised of a futures contract linked to the Underlying Index. The Underlying Index is a "price return" index, which means it reflects changes in the prices of its constituent stocks without taking account of the value of dividends paid on those stocks. As a result, an investor in the notes will not benefit from dividends paid on the constituent stocks of the Underlying Index.

●Owning the notes is not the same as a hypothetical direct investment in the Reference Asset or Underlying Index or a security or futures contract directly or indirectly linked to the Reference Asset or Underlying Index. — The return on your notes will not reflect the return you would realize if you made a hypothetical direct investment in the Reference Asset, Underlying Index or the underlying securities of the Underlying Index or a security or a futures contract directly or indirectly linked to the performance of the Reference Asset, Underlying Index or the underlying securities of the Underlying Index and held that investment for a similar period. Your notes may trade quite differently from the Reference Asset. Changes in the level of the Reference Asset may not result in comparable changes in the market value of your notes. Even if the level of the Reference Asset increases during the term of the notes, the market value of the notes prior to maturity may not increase to the same extent. It is also possible for the market value of the notes to decrease while the level of the Reference Asset increases.

●You will not have any shareholder rights and will have no right to receive any shares of any company included in the Underlying Index at maturity. — Investing in your notes will not make you a holder of any securities included in the Underlying Index. Neither you nor any other holder or owner of the notes will have any voting rights, any right to receive dividends or other distributions, or any other rights with respect to such underlying securities.

●We have no affiliation with the index sponsor and will not be responsible for the index sponsor's actions. — The sponsor of the Reference Asset is not our affiliate and will not be involved in the offering of the notes in any way. Consequently, we have no control over the actions of the index sponsor, including any actions of the type that would require the calculation agent to adjust the payment to you at maturity. The index sponsor has no obligation of any sort with respect to the notes. Thus, the index sponsor has no obligation to take your interests into consideration for any reason, including in taking any actions that might affect the value of the notes. None of our proceeds from the issuance of the notes will be delivered to the index sponsor.

●You must rely on your own evaluation of the merits of an investment linked to the Reference Asset. — In the ordinary course of their businesses, our affiliates from time to time may express views on expected movements in the levels of the Reference Asset or the prices of the securities included in the Reference Asset. One or more of our affiliates have published, and in the future may publish, research reports that express views on the Reference Asset or these securities. However, these views are subject to change from time to time. Moreover, other professionals who deal in the markets relating to the Reference Asset at any time may have significantly different views from those of our affiliates. You are encouraged to derive information concerning the Reference Asset from multiple sources, and you should not rely on the views expressed by our affiliates. Neither the offering of the notes nor any views which our affiliates from time to time may express in the ordinary course of their businesses constitutes a recommendation as to the merits of an investment in the notes.

General Risk Factors

●Your investment is subject to the credit risk of Bank of Montreal. — Our credit ratings and credit spreads may adversely affect the market value of the notes. Investors are dependent on our ability to pay any amounts due on the notes, and therefore investors are subject to our credit risk and to changes in the market’s view of our creditworthiness. Any decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the value of the notes.

●Potential conflicts. — We and our affiliates play a variety of roles in connection with the issuance of the notes, including acting as calculation agent. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the notes. We or one or more of our affiliates may also engage in trading of securities included in the Reference Asset on a regular basis as part of our general broker-dealer and other businesses, for proprietary accounts, for other accounts under management or to facilitate transactions for our customers. Any of these activities could adversely affect the level of the Reference Asset and, therefore, the market value of, and the payments on, the notes. We or one or more of our affiliates may also issue or underwrite other securities or financial or derivative instruments with returns linked or related to changes in the performance of the Reference Asset . By introducing competing products into the marketplace in this manner, we or one or more of our affiliates could adversely affect the market value of the notes.

●Our initial estimated value of the notes will be lower than the price to public. — Our initial estimated value of the notes is only an estimate, and is based on a number of factors. The price to public of the notes will exceed our initial estimated value, because costs associated with offering, structuring and hedging the notes are included in the price to public, but are not included in the estimated value. These costs include any underwriting discount and selling concessions, the profits that we and our affiliates expect to realize for assuming the risks in hedging our obligations under the notes and the estimated cost of hedging these obligations. The initial estimated value of the notes may be as low as the amount indicated on the cover page hereof.

●Our initial estimated value does not represent any future value of the notes, and may also differ from the estimated value of any other party. — Our initial estimated value of the notes as of the date hereof is, and our estimated value as determined on the Pricing Date will be, derived using our internal pricing models. This value is based on market conditions and other relevant factors, which include volatility of the Reference Asset , dividend rates and interest rates. Different pricing models and assumptions could provide values for the notes that are greater than or less than our initial estimated value. In addition, market conditions and other relevant factors after the Pricing Date are expected to change, possibly rapidly, and our assumptions may prove to be incorrect. After the Pricing Date, the value of the notes could change dramatically due to changes in market conditions, our creditworthiness, and the other factors set forth herein and in the product supplement. These changes are likely to impact the price, if any, at which we or BMOCM would be willing to purchase the notes from you in any secondary market transactions. Our initial estimated value does not represent a minimum price at which we or our affiliates would be willing to buy your notes in any secondary market at any time.

●The terms of the notes are not determined by reference to the credit spreads for our conventional fixed-rate debt. — To determine the terms of the notes, we will use an internal funding rate that represents a discount from the credit spreads for our conventional fixed-rate debt. As a result, the terms of the notes are less favorable to you than if we had used a higher funding rate.

●Certain costs are likely to adversely affect the value of the notes. — Absent any changes in market conditions, any secondary market prices of the notes will likely be lower than the price to public. This is because any secondary market prices will likely take into account our then-current market credit spreads, and because any secondary market prices are likely to exclude all or a portion of any underwriting discount and selling concessions, and the hedging profits and estimated hedging costs that are included in the price to public of the notes and that may be reflected on your account statements. In addition, any such price is also likely to reflect a discount to account for costs associated with establishing or unwinding any related hedge transaction, such as dealer discounts, mark-ups and other transaction costs. As a result, the price, if any, at which BMOCM or any other party may be willing to purchase the notes from you in secondary market transactions, if at all, will likely be lower than the price to public. Any sale that you make prior to the Maturity Date could result in a substantial loss to you.

●Lack of liquidity. — The notes will not be listed on any securities exchange. BMOCM may offer to purchase the notes in the secondary market, but is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily. Because other dealers are not likely to make a secondary market for the notes, the price at which you may be able to trade the notes is likely to depend on the price, if any, at which BMOCM is willing to buy the notes.

●Hedging and trading activities. — We or any of our affiliates have carried out or may carry out hedging activities related to the notes, including purchasing or selling shares of securities included in the Reference Asset, futures or options relating to the Reference Asset or securities included in the Reference Asset or other derivative instruments with returns linked or related to changes in the performance on the Reference Asset or securities included in the Reference Asset. We or our affiliates may also trade in the securities included in the Reference

Asset or instruments related to the Reference Asset or such securities from time to time. Any of these hedging or trading activities on or prior to the Pricing Date and during the term of the notes could adversely affect the payments on the notes.

●Many economic and market factors will influence the value of the notes. — In addition to the level of the Reference Asset and interest rates on any trading day, the value of the notes will be affected by a number of economic and market factors that may either offset or magnify each other, and which are described in more detail in the product supplement.

●Significant aspects of the tax treatment of the notes are uncertain. — The tax treatment of the notes is uncertain. We do not plan to request a ruling from the Internal Revenue Service or from any Canadian authorities regarding the tax treatment of the notes, and the Internal Revenue Service or a court may not agree with the tax treatment described herein.
The Internal Revenue Service has released a notice that may affect the taxation of holders of “prepaid forward contracts” and similar instruments. According to the notice, the Internal Revenue Service and the U.S. Treasury are actively considering whether the holder of such instruments should be required to accrue ordinary income on a current basis. While it is not clear whether the notes would be viewed as similar to such instruments, it is possible that any future guidance could materially and adversely affect the tax consequences of an investment in the notes, possibly with retroactive effect.
Please read carefully the section entitled "U.S. Federal Tax Information" herein, the section entitled "Supplemental Tax Considerations–Supplemental U.S. Federal Income Tax Considerations" in the accompanying product supplement, the section entitled "United States Federal Income Taxation" in the accompanying prospectus and the section entitled "Certain Income Tax Consequences" in the accompanying prospectus supplement. You should consult your tax advisor about your own tax situation.

Examples of the Hypothetical Payment at Maturity for a $1,000 Investment in the Notes

The following table illustrates the hypothetical payments on a note at maturity. The hypothetical payments are based on a $1,000 investment in the note, a hypothetical Initial Level of 100.00, a hypothetical Upside Leverage Factor of 178.50%, a hypothetical Barrier Level of 70.00 (70.00% of the hypothetical Initial Level), a range of hypothetical Final Levels and the effect on the payment at maturity.

The hypothetical examples shown below are intended to help you understand the terms of the notes. The actual cash amount that you will receive at maturity will depend upon the Final Level of the Reference Asset. You may lose some or all of the principal amount at maturity.


Hypothetical Final Level	Hypothetical Final Level Expressed as a Percentage of the Initial Level	Hypothetical Payment at Maturity	Hypothetical Return on the Notes
200.00	200.00%	$2,785.00	178.50%
180.00	180.00%	$2,428.00	142.80%
160.00	160.00%	$2,071.00	107.10%
140.00	140.00%	$1,714.00	71.40%
120.00	120.00%	$1,357.00	35.70%
100.00	100.00%	$1,000.00	0.00%
90.00	90.00%	$1,000.00	0.00%
80.00	80.00%	$1,000.00	0.00%
70.00	70.00%	$1,000.00	0.00%
69.99	69.99%	$699.90	-30.01%
60.00	60.00%	$600.00	-40.00%
40.00	40.00%	$400.00	-60.00%
20.00	20.00%	$200.00	-80.00%
0.00	0.00%	$0.00	-100.00%

The following examples illustrate how the returns set forth in the table above are calculated.

Example 1: The level of the Reference Asset decreases from the hypothetical Initial Level of 100.00 to a hypothetical Final Level of 60.00, representing a Percentage Change of –40.00%. Because the Percentage Change of the Reference Asset is negative and its hypothetical Final Level is less than its Barrier Level, the investor receives a payment at maturity of $600.00 per $1,000 in principal amount of the notes, calculated as follows:

$1,000 + ($1,000 x – 40.00%) = $600.00

Example 2: The level of the Reference Asset decreases from the hypothetical Initial Level of 100.00 to a hypothetical Final Level of 90.00, representing a Percentage Change of -10.00%. Although the Percentage Change of the Reference Asset is negative, because its hypothetical Final Level is greater than its Barrier Level, the investor receives a payment at maturity equal to the principal amount of the notes.

Example 3: The level of the Reference Asset increases from the hypothetical Initial Level of 100.00 to a hypothetical Final Level of 120.00, representing a Percentage Change of 20.00%. Because the hypothetical Final Level of the Reference Asset is greater than its hypothetical Initial Level, the investor receives a payment at maturity of $1,357.00 per $1,000 in principal amount of the notes, calculated as follows:

$1,000 + $1,000 x (20.00% x 178.50%) = $1,357.00

U.S. Federal Tax Information

By purchasing the notes, each holder agrees (in the absence of a change in law, an administrative determination or a judicial ruling to the contrary) to treat each note as a pre-paid derivative contract for U.S. federal income tax purposes. In the opinion of our counsel, Mayer Brown LLP, it would generally be reasonable to treat the notes as pre-paid derivative contracts in respect of the Reference Asset for U.S. federal income tax purposes. However, the U.S. federal income tax consequences of your investment in the notes are uncertain and the Internal Revenue Service could assert that the notes should be taxed in a manner that is different from that described in the preceding sentence. Please see the discussion in the product supplement dated March 25, 2025 under “Supplemental Tax Considerations—Supplemental U.S. Federal Income Tax Considerations—Notes Treated as Pre-Paid Derivative Contracts,” which applies to the notes.

Supplemental Plan of Distribution (Conflicts of Interest)

BMOCM will purchase the notes from us at a purchase price reflecting the commission set forth on the cover hereof. BMOCM has informed us that, as part of its distribution of the notes, it will reoffer the notes to other dealers who will sell them. Each such dealer, or each additional dealer engaged by a dealer to whom BMOCM reoffers the notes, will receive a commission from BMOCM, which will not exceed the commission set forth on the cover page. We or one of our affiliates may also pay a referral fee to certain dealers in connection with the distribution of the notes.

Certain dealers who purchase the notes for sale to certain fee-based advisory accounts may forego some or all of their selling concessions, fees or commissions. The public offering price for investors purchasing the notes in these accounts may be less than 100% of the principal amount, as set forth on the cover page of this document. Investors that hold their notes in these accounts may be charged fees by the investment advisor or manager of that account based on the amount of assets held in those accounts, including the notes.

We will deliver the notes on a date that is greater than one business day following the pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes more than one business day prior to the issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

We own, directly or indirectly, all of the outstanding equity securities of BMOCM, the agent for this offering. In accordance with FINRA Rule 5121, BMOCM may not make sales in this offering to any of its discretionary accounts without the prior written approval of the customer.

We reserve the right to withdraw, cancel or modify the offering of the notes and to reject orders in whole or in part. You may cancel any order for the notes prior to its acceptance.

You should not construe the offering of the notes as a recommendation of the merits of acquiring an investment linked to the Reference Asset or as to the suitability of an investment in the notes.

BMOCM may, but is not obligated to, make a market in the notes. BMOCM will determine any secondary market prices that it is prepared to offer in its sole discretion.

We may use the final pricing supplement relating to the notes in the initial sale of the notes. In addition, BMOCM or another of our affiliates may use the final pricing supplement in market-making transactions in any notes after their initial sale. Unless BMOCM or we inform you otherwise in the confirmation of sale, the final pricing supplement is being used by BMOCM in a market-making transaction.

For a period of approximately three months following issuance of the notes, the price, if any, at which we or our affiliates would be willing to buy the notes from investors, and the value that BMOCM may also publish for the notes through one or more financial information vendors and which could be indicated for the notes on any brokerage account statements, will reflect a temporary upward adjustment from our estimated value of the notes that would otherwise be determined and applicable at that time. This temporary upward adjustment represents a portion of (a) the hedging profit that we or our affiliates expect to realize over the term of the notes and (b) any underwriting discount and the selling concessions paid in connection with this offering. The amount of this temporary upward adjustment will decline to zero on a straight-line basis over the three-month period.

Switzerland. This pricing supplement is not intended to constitute an offer or solicitation to purchase or invest in any notes. Neither this pricing supplement nor any other offering or marketing material relating to the notes constitutes a prospectus compliant with the requirements of articles 35 et seq. of the Swiss Financial Services Act ("FinSA") for a public offering of the notes in Switzerland and no such prospectus has been or will be prepared for or in connection with the offering of the notes in Switzerland.

Neither this pricing supplement nor any other offering or marketing material relating to the notes has been or will be filed with or approved by a Swiss review body (Prüfstelle).

The notes may not be publicly offered, directly or indirectly, in Switzerland within the meaning of FinSA except (i) in any circumstances falling within the exemptions to prepare a prospectus listed in article 36 para. 1 FinSA or (ii) where such offer does not qualify as a public offer in Switzerland, provided always that no offer of notes shall require the Issuer or any offeror to publish a prospectus pursuant to article 35 FinSA in respect to such offer and that such offer shall comply with the additional restrictions set out below (if applicable). The Issuer has not authorised and does not authorise any offer of notes which would require the Issuer or any offeror to publish a prospectus pursuant to article 35 FinSA in respect of such offer. For purposes of this provision "public offer" shall have the meaning as such term is understood pursuant to article 3 lit. g and h FinSA and the Swiss Financial Services Ordinance ("FinSO").

The notes do not constitute participations in a collective investment scheme within the meaning of the Swiss Collective Investment Schemes Act.

Additional Information Relating to the Estimated Initial Value of the Notes

Our estimated initial value of the notes on the date hereof , and that will be set forth on the cover page of the final pricing supplement relating to the notes, equals the sum of the values of the following hypothetical components:

●a fixed-income debt component with the same tenor as the notes, valued using our internal funding rate for structured notes; and

●one or more derivative transactions relating to the economic terms of the notes.

The internal funding rate used in the determination of the initial estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. The value of these derivative transactions is derived from our internal pricing models. These models are based on factors such as the traded market prices of comparable derivative instruments and on other inputs, which include volatility, dividend rates, interest rates and other factors. As a result, the estimated initial value of the notes on the Pricing Date will be determined based on the market conditions on the Pricing Date.

The S&P 500^® Futures Excess Return Index

The S&P 500^® Futures Excess Return Index (the “SPXFP”) measures the performance of the nearby quarterly E-mini S&P 500 futures contract trading on the Chicago Mercantile Exchange. E-mini S&P 500 futures contracts are quarterly contracts to buy or sell standardized “contract units”. One contract unit of the E-mini S&P 500 futures contracts equals $50 multiplied by the index value of the S&P 500^® Index (the “SPX”) (price return version).

The SPXFP is calculated, maintained and published by S&P Dow Jones Indices LLC (“S&P”) and is part of the S&P Dow Jones Indices family of indices. Additional information is available on the following websites: spglobal.com/spdji/en/indices/other-strategies/sp-500-futures-index/ and spglobal.com (the “SPX websites”). We are not incorporating by reference the websites mentioned in the preceding sentence or any material included thereon in this document.

The level of the S&P 500^® Futures Excess Return Index is published on Bloomberg Professional^® service (“Bloomberg”) under the ticker symbol “SPXFP.”

Calculation of the S&P 500^® Futures Excess Return Index

The SPXFP is constructed from the front-quarter E-mini S&P 500 futures contract and includes a provision for the replacement of the current E-mini S&P 500 futures contract as the contract approaches maturity (also referred to as “rolling” or “the roll”). This replacement occurs over a one-day rolling period every March, June, September, and December, effective after the close of trading five business days preceding the last trading date of the relevant E-mini S&P 500 futures contract.

The SPXFP is calculated from the price change of the underlying E-mini S&P 500 futures contract. The level of the SPXFP on the relevant trading day equals (a) the level of the SPXFP on the previous trading day multiplied by (b) one plus the contract daily return on the relevant trading day.

On each trading day, the contract daily return equals the quotient of (a) the daily contract reference price (the official closing price per futures contract on the Chicago Mercantile Exchange) on the relevant trading day divided by (b) the daily contract reference price on the immediately preceding trading day.

The index committee of the SPXFP (the “SPXFP Index Committee”) maintains the SPXFP. The SPXFP Index Committee reserves the right to make exceptions when applying the methodology or to modify the methodology if the need arises.

S&P may recalculate the SPXFP if settlement prices are amended or there is a deviation from the rules in the index methodology. If amended settlement prices due to vendor errors or exchange updates are discovered within two trading days of its occurrence, S&P may, at its discretion, recalculate the SPXFP without involving the SPXFP Index Committee. In the event any such recalculation event is discovered beyond the two trading day period, the SPXFP Index Committee shall decide whether the SPXFP should be recalculated. Errors identified prior to the next trading day’s open are typically corrected and the SPXFP is reposted. Other errors are reviewed by the SPXFP Index Committee, which then determines what, if any, actions should be taken. Errors due to S&P data entry errors, methodology misapplication or other similar errors are reviewed by the SPXFP Index Committee, which then determines whether the SPXFP should be recalculated and reposted.

The S&P 500^® Index

The SPX includes a representative sample of 500 companies in leading industries of the U.S. economy. The SPX is intended to provide a performance benchmark for large-cap, U.S. domiciled equity markets. The 500 companies that are chosen for inclusion in the SPX are selected with an aim of achieving a distribution by broad industry groupings that approximates the distribution of such groupings in the common stock population of the large-cap U.S.-domiciled equity market.

The SPX is calculated, maintained and published by S&P and is part of the S&P Dow Jones Indices family of indices. Additional information is available on the following websites: spglobal.com/spdji/en/indices/equity/sp-500 and spglobal.com (the “SPX websites”). We are not incorporating by reference the websites mentioned in the preceding sentence or any material included thereon in this document.

The level of the S&P 500^® Index is published on Bloomberg under the ticker symbol “SPX.”

Constituents

S&P intends for the SPX to provide a performance benchmark for the large-cap U.S. domiciled equity markets. Constituent changes are made on an as-needed basis and there is no schedule for constituent reviews. Index additions and deletions are announced with at least three business days advance notice. Less than three business days’ notice may be given at the discretion of an index committee (the “S&P Index Committee”).

Certain types of organizational structures and securities are always excluded from the SPX, including, but not limited to, business development companies (BDCs), limited partnerships, limited liability companies (LLCs), closed-end funds, ETFs, ETNs, preferred stock and convertible preferred stock, convertible bonds, investment trusts and American depositary receipts (ADRs). Stocks are deleted from the SPX when they are involved in mergers, acquisitions or significant restructurings such that they no longer meet the inclusion criteria, and when they substantially violate one or more of the addition criteria. Stocks that are delisted or moved to the pink sheets or the bulletin board are removed, and those that experience a trading halt may be retained or removed in S&P’s discretion. S&P evaluates additions and deletions with a view to maintaining SPX continuity.

Calculation and Maintenance

The SPX is calculated using a base-weighted aggregate methodology. The level of the SPX on any day for which an index level is published is determined by a fraction, the numerator of which is the aggregate of the market price of each stock in the SPX times the number of shares of such stock included in the SPX, and the denominator of which is the index divisor. The “market value” of any index stock is the product of the market price per share of that stock times the number of the then-outstanding shares of such index stock that are then included in the SPX.

The “index divisor” is a value calculated by S&P that is intended to maintain conformity in index values over time and is adjusted for all changes in the index stocks’ share capital after the “base date” as described below. The level of the SPX reflects the total market value of all index stocks relative to the SPX’s base period of 1941-1943.

In addition, the SPX is float-adjusted, meaning that the share counts used in calculating the SPX reflect only those shares available to investors rather than all of a company’s outstanding shares. S&P seeks to exclude shares held by long-term, strategic shareholders concerned with the control of a company by excluding all shareholdings of officers, directors and other related individuals whose holdings are publicly disclosed and all shareholdings with a position greater than 5% of the outstanding shares of a company (other than the holdings of certain “passive” holders), from the float-adjusted share count.

S&P calculates an IWF for each stock that is part of the numerator of the float-adjusted index fraction described above:

IWF = (available float shares)/(total shares outstanding)

where available float shares is defined as total shares outstanding less shares held by strategic shareholders. In most cases, an IWF is reported to the nearest one percentage point. For companies with multiple share class lines, a separate IWF is calculated for each share class line. For constituents included in the SPX prior to July 31, 2017, all publicly listed multiple share class lines were included separately in the SPX, subject to such share class line satisfying the SPX’s liquidity and float criteria and subject to certain exceptions. As of July 31, 2017, companies with multiple share class lines are no longer eligible for inclusion in the SPX. Only common shares are considered when determining whether a company has a multiple share class structure.

The SPX maintenance process involves maintaining quality assurance processes and procedures, adjusting the number of shares used to calculate the SPX, monitoring and completing the adjustments for company additions and deletions, adjusting for stock splits and stock dividends and adjusting for other corporate actions. There is a large range of corporate actions that may affect companies included in the SPX. Certain corporate actions require S&P to recalculate the share count or the float adjustment or to make an adjustment to the divisor to prevent the value of the SPX from changing as a result of the corporate action. This helps ensure that the movement of the SPX does not reflect the corporate actions of individual companies in the SPX. Additional information regarding changes to the SPX that may result from corporate actions is available in the relevant methodology on the SPX websites.

The methodology also provides information on what adjustments, if any, will be made for unexpected exchange closures or trading halts, including halts affecting an individual constituent while markets generally remain open.

The S&P Index Committee serves as the index governance body and oversees the design, maintenance, and publication of the SPX. In addition to its daily governance of indices and maintenance of the SPX methodology, at least once within any 12 month period, the S&P Index Committee reviews the SPX methodology. The S&P Index Committee may at times consult with investors, market participants, security issuers included in or potentially included in the SPX, or investment and financial experts.
