Senior Medium-Term Notes, Series K
Step Down Autocallable Barrier Notes with Step Up Call Amount due July 15, 2030
Linked to the S&P 500® Index

The notes are designed for investors who are willing to forego interest payments and are seeking a return equal to the applicable Call Amount (as set forth herein under “Key Terms of the Notes”), which represents a return equal to approximately 8.20% per annum, if the closing level of the S&P 500® Index (the “Reference Asset”) on any quarterly Observation Date beginning in July 2027 is greater than or equal to its Call Level (as defined below). The Call Level of the Reference Asset will be set with respect to each Observation Date, and the Call Level on any particular Observation Date may be higher or lower that the Call Level on other Observation Dates. The Call Level for the Reference Asset on each Observation Date is set forth under “Key Terms of the Notes.” Investors should be willing to have their notes automatically redeemed prior to maturity, be willing to forego any potential to participate in any increase in the level of the Reference Asset, be willing to forego any interest and be willing to lose some or all of their principal at maturity.

Beginning on July 12, 2027, if on any Observation Date, the closing level of the Reference Asset is greater than or equal to its Call Level, the notes will be automatically redeemed. On the corresponding settlement date (the “Call Settlement Date”), investors will receive their principal amount plus the Call Amount corresponding to the applicable Observation Date. After the notes are redeemed, investors will not receive any additional payments in respect of the notes.

The notes do not guarantee any return of principal at maturity. Instead, if the notes are not automatically redeemed, the payment at maturity will be based on the Final Level of the Reference Asset and whether the Final Level of the Reference Asset has declined from its Initial Level to below its Trigger Level on the Valuation Date (a “Trigger Event”), as described below.

If the notes are not automatically redeemed and a Trigger Event has occurred, investors will lose 1% of the principal amount for each 1% decrease in the level of the Reference Asset from its Initial Level to its Final Level. In such a case, you will receive a cash amount at maturity that is less than the principal amount.

Investing in the notes is not equivalent to a hypothetical direct investment in the Reference Asset.

The notes do not bear interest. The notes will not be listed on any securities exchange.

All payments on the notes are subject to the credit risk of Bank of Montreal.

The notes will be issued in minimum denominations of $1,000 and integral multiples of $1,000.

Our subsidiary, BMO Capital Markets Corp. (“BMOCM”), is the agent for this offering. See “Supplemental Plan of Distribution (Conflicts of Interest)” below.

The notes will not be subject to conversion into our common shares or the common shares of any of our affiliates under subsection 39.2(2.3) of the Canada Deposit Insurance Corporation Act (the “CDIC Act”).

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 notes are not automatically redeemed, the payment at maturity will be based on the Final Level and whether a Trigger Event has occurred. If the Final Level is less than its Trigger Level, a Trigger Event will occur, and 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 notes are subject to automatic early redemption. — We will redeem the notes if the closing level of the Reference Asset on any Observation Date is greater than or equal to its Call Level. Following an automatic redemption, you may not be able to reinvest your proceeds in an investment with returns that are comparable to the notes. Furthermore, to the extent you are able to reinvest such proceeds in an investment with a comparable return for a similar level of risk, you may incur transaction costs such as dealer discounts and hedging costs built into the price of the new notes.

Your return on the notes is limited to the potential Call Amount regardless of any increase in the level of the Reference Asset. — You will not receive a payment with a value greater than your principal amount plus the applicable Call Amount, even if the Final Level of the Reference Asset exceeds its Call Level by a substantial amount. Accordingly, your maximum return on the applicable notes is limited to the potential return represented by the Call Amounts.

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 fixed interest payments. 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.

Higher Call Amounts or a lower Trigger Level may reflect greater expected volatility of the Reference Asset, and greater expected volatility generally indicates an increased risk of loss at maturity. — The economic terms for the notes, including the Call Amounts, Call Levels and Trigger Level, are based, in part, on the expected volatility of the Reference Asset at the time the terms of the notes are set. “Volatility” refers to the frequency and magnitude of changes in the level of the Reference Asset. The greater the expected volatility of the Reference Asset as of the Pricing Date, the greater the expectation is as of that date that a Trigger Event could occur and, as a consequence, an increased risk of loss. All things being equal, this greater expected volatility will generally be reflected in higher potential Call Amounts than the yield payable on our conventional debt securities with a similar maturity or on otherwise comparable securities, and/or a lower Trigger Level than those terms on otherwise comparable securities. Therefore, relatively higher potential Call Amounts may indicate an increased risk of loss. Further, relatively a lower Trigger Level may not necessarily indicate that the notes have a greater likelihood of a return of principal at maturity. You should be willing to accept the downside market risk of the Reference Asset and the potential to lose a significant portion or all of your initial investment.

Risks Related to the Reference Asset

Owning the notes is not the same as a hypothetical direct investment in the Reference Asset or a security directly linked to the Reference Asset. — The return on your notes will not reflect the return you would realize if you made a hypothetical direct investment in the Reference Asset or the underlying securities of the Reference Asset or a security directly linked to the performance of the Reference Asset or the underlying securities of the Reference Asset 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 levels of the Reference Asset increase 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 levels of the Reference Asset increase.

You will not have any shareholder rights and will have no right to receive any shares of any company included in the Reference Asset at maturity. — Investing in your notes will not make you a holder of any securities included in the Reference Asset. 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 any 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 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 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 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 Payments for a $1,000 Investment in the Notes

The following examples illustrate the hypothetical payments on a note upon an automatic call or at maturity. The hypothetical payments are based on a $1,000 investment in the note, a hypothetical Initial Level of 100.00, a hypothetical Trigger Level of 70.00 (70.00% of the hypothetical Initial Level), a hypothetical Call Level of 100.00 with respect to the first through twelfth Observation Dates (100.00% of the hypothetical Initial Level) and 70.00 with respect to the thirteenth Observation Date (70.00% of the hypothetical Initial Level), hypothetical Call Amounts representing a return of approximately 8.20% per annum, a range of hypothetical closing levels and the effect on the payment of the notes.

The hypothetical examples shown below are intended to help you understand the terms of the notes. The actual cash amount that you will receive will depend upon the level of the Reference Asset on the Observation Dates and on the Valuation Date.

Hypothetical Examples of Amounts Payable Upon an Automatic Call – The following hypothetical examples illustrate how hypothetical payments are calculated upon an automatic call.

Example 1: The closing level of the Reference Asset increases by 10.00% from the Initial Level to a closing level of 110.00 on the first Observation Date. Because the closing level of the Reference Asset on the first Observation Date is greater than its Call Level, the investor receives on the first Call Settlement Date a cash payment of $1,082.00, representing the principal amount plus the corresponding hypothetical Call Amount. After the notes are called, they will no longer remain outstanding and there will be no further payments on the notes.

Example 2: The closing level of the Reference Asset decreases by 10.00% from the Initial Level to a closing level of 90.00 on the first Observation Date, but the closing level of the Reference Asset increases by 10.00% from the Initial Level to a closing level of 110.00 on the second Observation Date. Because the notes are not called on the first Observation Date and the closing level of the Reference Asset on the second Observation Date is greater than its Call Level, the investor receives on the second Call Settlement Date a cash payment of $1,102.50, representing the principal amount plus the corresponding hypothetical Call Amount. After the notes are called, they will no longer remain outstanding and there will be no further payments on the notes.

Example 3: The notes are not called on any of the Observation Dates prior to the final Observation Date, and the closing level of the Reference Asset increases by 20.00% from the Initial Level to 120.00 on the Valuation Date. Because the notes are not called on any of the preceding Observation Dates and the closing level of the Reference Asset on the Valuation Date is greater than its Call Level, the investor receives on the maturity date a cash payment of $1,328.00, representing the principal amount plus the corresponding hypothetical Call Amount.

Hypothetical Example of Amounts Payable at Maturity – The following hypothetical example illustrates how hypothetical payments at maturity are calculated, assuming the notes have not been automatically called.

Example 4: The closing level of the Reference Asset decreases by 40.00% from the Initial Level to its Final Level of 60.00 on the Valuation Date, which is less than its Trigger Level. The notes are not called on any Observation Date because the closing level of the Reference Asset is below its Call Level on each Observation Date (including the Valuation Date). Because the Final Level of the Reference Asset is less than its Initial Level as well as its Trigger Level, the investor receives at maturity, a cash payment of $600.00 per note, calculated as follows:

Principal Amount + (Principal Amount × Percentage Change of the Reference Asset)

= $1,000 + ($1,000 x -40.00%) = $1,000 - $400.00 = $600.00

The payments shown above are entirely hypothetical; they are based on levels of the Reference Asset that may not be achieved and on assumptions that may prove to be erroneous. The actual market value of your notes at maturity or at any other time, including any time you may wish to sell your notes, may bear little relation to the hypothetical payments at maturity shown above, and those amounts should not be viewed as an indication of the financial return on an investment in the notes or on an investment in the securities included in the Reference Asset.

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 accompanying product supplement under "Supplemental Tax Considerations—Supplemental U.S. Federal Income Tax Considerations—Notes Treated as Investment Units Consisting of a Debt Portion and a Put Option, as Pre-Paid Contingent Income-Bearing Derivative Contracts, or as Pre-Paid Derivative Contracts—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. We or one of our affiliates may also pay a referral fee to certain dealers in connection with the distribution of 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 the hedging profit that we or our affiliates expect to realize over the term of the notes. The amount of this temporary upward adjustment will decline to zero on a straight-line basis over the three-month period.

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® Index (“SPX”)

The S&P 500® Index measures the performance of the large-cap segment of the U.S. market. The S&P 500® Index includes 500 leading companies and covers approximately 80% of available market capitalization. The calculation of the level of the S&P 500® Index is based on the relative value of the aggregate market value of the common stocks of 500 companies as of a particular time compared to the aggregate average market value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943.

S&P calculates the S&P 500® Index by reference to the prices of the constituent stocks of the S&P 500® Index without taking account of the value of dividends paid on those stocks. As a result, the return on the notes will not reflect the return you would realize if you actually owned the constituent stocks of the S&P 500® Index and received the dividends paid on those stocks.

Computation of the S&P 500® Index

While S&P currently employs the following methodology to calculate the S&P 500® Index, no assurance can be given that S&P will not modify or change this methodology in a manner that may affect the Payment at Maturity.

Historically, the market value of any component stock of the S&P 500® Index was calculated as the product of the market price per share and the number of then outstanding shares of such component stock. In March 2005, S&P began shifting the S&P 500® Index halfway from a market capitalization weighted formula to a float-adjusted formula, before moving the S&P 500® Index to full float adjustment on September 16, 2005. S&P’s criteria for selecting stocks for the S&P 500® Index did not change with the shift to float adjustment. However, the adjustment affects each company’s weight in the S&P 500® Index.

Under float adjustment, the share counts used in calculating the S&P 500® Index reflect only those shares that are available to investors, not all of a company’s outstanding shares. Float adjustment excludes shares that are closely held by control groups, other publicly traded companies or government agencies.

In September 2012, all shareholdings representing more than 5% of a stock’s outstanding shares, other than holdings by “block owners,” were removed from the float for purposes of calculating the S&P 500® Index. Generally, these “control holders” will include officers and directors, private equity, venture capital and special equity firms, other publicly traded companies that hold shares for control, strategic partners, holders of restricted shares, ESOPs, employee and family trusts, foundations associated with the company, holders of unlisted share classes of stock, government entities at all levels (other than government retirement/pension funds) and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. However, holdings by block owners, such as depositary banks, pension funds, mutual funds and ETF providers, 401(k) plans of the company, government retirement/pension funds, investment funds of insurance companies, asset managers and investment funds, independent foundations and savings and investment plans, will ordinarily be considered part of the float.

Treasury stock, stock options, equity participation units, warrants, preferred stock, convertible stock, and rights are not part of the float. Shares held in a trust to allow investors in countries outside the country of domicile, such as depositary shares and Canadian exchangeable shares are normally part of the float unless those shares form a control block.

For each stock, an investable weight factor (“IWF”) is calculated by dividing the available float shares by the total shares outstanding. Available float shares are defined as the total shares outstanding less shares held by control holders. This calculation is subject to a 5% minimum threshold for control blocks. For example, if a company’s officers and directors hold 3% of the company’s shares, and no other control group holds 5% of the company’s shares, S&P would assign that company an IWF of 1.00, as no control group meets the 5% threshold. However, if a company’s officers and directors hold 3% of the company’s shares and another control group holds 20% of the company’s shares, S&P would assign an IWF of 0.77, reflecting the fact that 23% of the company’s outstanding shares are considered to be held for control. As of July 31, 2017, companies with multiple share class lines are no longer eligible for inclusion in the S&P 500® Index. Constituents of the S&P 500® Index prior to July 31, 2017 with multiple share class lines were grandfathered in and continue to be included in the S&P 500® Index. If a constituent company of the S&P 500® Index reorganizes into a multiple share class line structure, that company will remain in the S&P 500® Index at the discretion of the S&P Index Committee in order to minimize turnover.

The S&P 500® Index is calculated using a base-weighted aggregate methodology. The level of the S&P 500® Index reflects the total market value of all 500 component stocks relative to the base period of the years 1941 through 1943. An indexed number is used to represent the results of this calculation in order to make the level easier to use and track over time. The actual total market value of the component stocks during the base period of the years 1941 through 1943 has been set to an indexed level of 10. This is often indicated by the notation 1941-43 = 10. In practice, the daily calculation of the S&P 500® Index is computed by dividing the total market value of the component stocks by the “index divisor.” By itself, the index divisor is an arbitrary number. However, in the context of the calculation of the S&P 500® Index, it serves as a link to the original base period level of the S&P 500® Index. The index divisor keeps the S&P 500® Index comparable over time and is the manipulation point for all adjustments to the S&P 500® Index, which is index maintenance.

Index Maintenance

Index maintenance includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends, and stock price adjustments due to company restructuring or spinoffs. Some corporate actions, such as stock splits and stock dividends, require changes in the common shares outstanding and the stock prices of the companies in the S&P 500® Index, and do not require index divisor adjustments.

To prevent the level of the S&P 500® Index from changing due to corporate actions, corporate actions which affect the total market value of the S&P 500® Index require an index divisor adjustment. By adjusting the index divisor for the change in market value, the level of the S&P 500® Index remains constant and does not reflect the corporate actions of individual companies in the S&P 500® Index. Index divisor adjustments are made after the close of trading and after the calculation of the S&P 500® Index closing level.

Changes in a company’s total shares outstanding of 5% or more due to public offerings are made as soon as reasonably possible. Other changes of 5% or more (for example, due to tender offers, Dutch auctions, voluntary exchange offers, company stock repurchases, private placements, acquisitions of private companies or non-index companies that do not trade on a major exchange, redemptions, exercise of options, warrants, conversion of preferred stock, notes, debt, equity participations, at-the-market stock offerings or other recapitalizations) are made weekly, and are generally announced on Fridays for implementation after the close of trading the following Friday (one week later). If a 5% or more share change causes a company’s IWF to change by five percentage points or more, the IWF is updated at the same time as the share change. IWF changes resulting from partial tender offers are considered on a case-by-case basis.
