The Toronto-Dominion Bank (TD) 424B3Prospectus supplement

We reserve the right to change the terms of, or reject any offer to purchase, the Notes prior to their issuance. In the event of any changes to the terms of the Notes, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes, in which case we may reject your offer to purchase.

Selected Purchase Considerations

Additional Risk Factors

The Notes involve risks not associated with an investment in conventional debt securities. This section describes the most significant risks relating to the terms of the Notes. For additional information as to these risks, please see “Additional Risk Factors Specific to the Notes” in the product supplement and “Risk Factors” in the prospectus.

Investors should consult their investment, legal, tax, accounting and other advisors as to the risks entailed by an investment in the Notes and the suitability of the Notes in light of their particular circumstances.

Risks Relating to Return Characteristics

Your Investment in the Notes May Result in a Loss.

The Notes do not guarantee the return of the Principal Amount and you may lose up to your entire investment in the Notes. Specifically, if the Notes are not subject to an automatic call and the Final Level is less than the Barrier Level, you will lose 1% of the Principal Amount of the Notes for each 1% that the Final Level is less than the Initial Level, and may lose your entire Principal Amount.

The Notes Do Not Pay Interest and Your Return May Be Less than the Return on a Conventional Debt Security of Comparable Maturity.

There will be no periodic interest payments on the Notes as there would be on a conventional, fixed-rate or floating-rate debt security of comparable maturity. The return that you will receive on the 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 you may not receive the Call Premium or any positive return on the Notes. Even if your return is positive, your return may be less than that of a conventional, interest-bearing senior debt security of TD of comparable maturity. Your investment may not reflect the full opportunity cost to you when you take into account factors that affect the time value of money.

The Notes May Be Automatically Called Prior to the Maturity Date And Are Subject to Reinvestment Risk.

You Will Not Have Any Rights Associated with Owning the Reference Asset Constituents.

Your return on the Notes may be less than that of a hypothetical direct investment in the Reference Asset or the stocks and other assets comprising the Reference Asset (the “Reference Asset Constituents”). Investing in the Notes will not make you a holder of the shares of the Reference Asset Constituents and you will not have any voting rights, any rights to receive dividends or other distributions or any

rights against the issuers of the Reference Asset Constituents (the “Reference Asset Constituent Issuers”). Your Notes will be paid in cash and you will have no right to receive delivery of shares of the Reference Asset Constituents.

The Amount Payable on the Notes, if Any, is not Linked to the Level of the Reference Asset at any Time Other Than on the Review Date or Valuation Date.

Risks Relating to Characteristics of the Reference Asset

There Are Market Risks Associated with the Reference Asset.

The level of the Reference Asset can rise or fall sharply due to factors specific to the Reference Asset, the Reference Asset Constituents and the Reference Asset Constituent Issuers, such as stock price volatility, earnings, financial conditions, corporate, industry and regulatory developments, management changes and decisions and other events, as well as general market factors, such as general stock market volatility and levels, interest rates and economic and political conditions. You, as an investor in the Notes, should make your own investigation into the Reference Asset, the Reference Asset Constituents and the Reference Asset Constituent Issuers for your Notes. For additional information, see “Information Regarding the Reference Asset” herein.

We Have No Affiliation with the Index Sponsor and Will Not Be Responsible for Any Actions Taken by the Index Sponsor.

The index sponsor as specified under “Information Regarding the Reference Asset” (the “Index Sponsor”) is neither an affiliate of ours nor involved in any offerings of the Notes in any way. Consequently, we have no control of any actions of the Index Sponsor, including any actions of the type that could adversely affect the level of the Reference Asset or the return on the Notes. The Index Sponsor does not have any 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 market value of, or return on, the Notes. None of our proceeds from any issuance of the Notes will be delivered to the Index Sponsor, except to the extent that we are required to pay the Index Sponsor licensing fees with respect to the Reference Asset.

Changes that Affect the Reference Asset May Adversely Affect the Market Value of, and Return on, the Notes.

The policies of the Index Sponsor concerning the calculation of the Reference Asset, additions, deletions or substitutions of the Reference Asset Constituents and the manner in which changes affecting those Reference Asset Constituents, such as stock dividends, reorganizations or mergers, may be reflected in the Reference Asset and could adversely affect the market value of, and return on, the Notes. The market value of, and return on, the Notes could also be affected if the Index Sponsor changes these policies, for example, by changing the manner in which it calculates the Reference Asset, or if the Index Sponsor discontinues or suspends calculation or publication of the Reference Asset. If events such as these occur, the Calculation Agent may select a successor index or take other actions as discussed in the product supplement and, notwithstanding these adjustments, the market value of, and return on, the Notes may be adversely affected.

The S&P 500^® Index Reflects Price Return, Not Total Return.

The return on the Notes is based on the performance of the S&P 500^® Index, which reflects the changes in the market prices of its Reference Asset Constituents. The S&P 500^® Index is not a “total return” index or strategy, which, in addition to reflecting those price returns, would also reflect any dividends paid on the Reference Asset Constituents. The return on the Notes will not include such a total return feature or dividend component.

Risks Relating to Estimated Value and Liquidity

The Estimated Value of Your Notes Is Expected To Be Less Than the Public Offering Price of Your Notes.

The estimated value of your Notes on the Pricing Date is expected to be less than the public offering price of your Notes. The difference between the public offering price of your Notes and the estimated value of the Notes reflects costs and expected profits associated with selling and structuring the Notes, as well as hedging our obligations under the Notes. Because hedging our obligations entails risks and may be influenced by market forces beyond our control, this hedging may result in a profit that is more or less than expected, or a loss.

The Estimated Value of Your Notes Is Based on Our Internal Funding Rate.

The estimated value of your Notes on the Pricing Date is determined by reference to our internal funding rate. The internal funding rate used in the determination of the estimated value of the Notes generally represents a discount from the credit spreads for our conventional, fixed-rate debt securities and the borrowing rate we would pay for our conventional, fixed-rate debt securities. This discount is based on, among other things, our view of the funding value of the Notes as well as the higher issuance, operational and ongoing liability management costs of the Notes in comparison to those costs for our conventional, fixed-rate debt, as well as estimated financing costs of any hedge positions, taking into account regulatory and internal requirements. If the interest rate implied by the credit spreads for our conventional, fixed-rate debt securities, or the borrowing rate we would pay for our conventional, fixed-rate debt securities were to be used, we would expect the economic terms of the Notes to be more favorable to you. Additionally, assuming all other economic terms are held constant, the use of an internal funding rate for the Notes is expected to increase the estimated value of the Notes at any time.

The estimated value of your Notes on the Pricing Date is based on our internal pricing models when the terms of the Notes are set, which take into account a number of variables, such as our internal funding rate on the Pricing Date, and are based on a number of subjective assumptions, which are not evaluated or verified on an independent basis and may or may not materialize. Further, our pricing models may be different from other financial institutions’ pricing models and the methodologies used by us to estimate the value of the Notes may not be consistent with those of other financial institutions that may be purchasers or sellers of Notes in the secondary market. As a result, the secondary market price of your Notes may be materially less than the estimated value of the Notes determined by reference to our internal pricing models. In addition, market conditions and other relevant factors in the future may change, and any assumptions may prove to be incorrect.

The Estimated Value of Your Notes Is Not a Prediction of the Prices at Which You May Sell Your Notes in the Secondary Market, If Any, and Such Secondary Market Prices, If Any, Will Likely be Less Than the Public Offering Price of Your Notes and May Be Less Than the Estimated Value of Your Notes.

The estimated value of the Notes is not a prediction of the prices at which the Agent, other affiliates of ours or third parties may be willing to purchase the Notes from you in secondary market transactions (if they are willing to purchase, which they are not obligated to do). The price at which you may be able to sell your Notes in the secondary market at any time, if any, will be influenced by many factors that cannot be predicted, such as market conditions, and any bid and ask spread for similar sized trades, and may be substantially less than the estimated value of the Notes. Further, as secondary market prices of your Notes take into account the levels at which our debt securities trade in the secondary market, and do not take into account our various costs and expected profits associated with selling and structuring the Notes, as well as hedging our obligations under the Notes, secondary market prices of your Notes will likely be less than the public offering price of your Notes. As a result, the price at which the Agent, other affiliates of ours or third parties may be willing to purchase the Notes from you in secondary market transactions, if any, will likely be less than the price you paid for your Notes, and any sale prior to the Maturity Date could result in a substantial loss to you.

The Temporary Price at Which the Agent May Initially Buy the Notes in the Secondary Market May Not Be Indicative of Future Prices of Your Notes.

Assuming that all relevant factors remain constant after the Pricing Date, the price at which the Agent may initially buy or sell the Notes in the secondary market (if the Agent makes a market in the Notes, which it is not obligated to do) may exceed the estimated value of the Notes on the Pricing Date, as well as the secondary market value of the Notes, for a temporary period after the Issue Date of the Notes, as discussed further under “Additional Information Regarding the Estimated Value of the Notes.” The price at which the Agent may initially buy or sell the Notes in the secondary market may not be indicative of future prices of your Notes.

The Underwriting Discount, Offering Expenses and Certain Hedging Costs Are Likely to Adversely Affect Secondary Market Prices.

Assuming no changes in market conditions or any other relevant factors, the price, if any, at which you may be able to sell the Notes will likely be less than the public offering price. The public offering price includes, and any price quoted to you is likely to exclude, the underwriting discount paid in connection with the initial distribution, offering expenses as well as the cost of hedging our obligations under the Notes. In addition, any such price is also likely to reflect dealer discounts, mark-ups and other transaction costs, such as a discount to account for costs associated with establishing or unwinding any related hedge transaction.

There May Not Be an Active Trading Market for the Notes — Sales in the Secondary Market May Result in Significant Losses.

There may be little or no secondary market for the Notes. The Notes will not be listed or displayed on any securities exchange or any electronic communications network. The Agent or another of our affiliates may make a market for the Notes; however, they are not required to do so and may stop any market-making activities at any time. Even if a secondary market for the Notes develops, it may not provide significant liquidity or trade at prices advantageous to you. We expect that transaction costs in any secondary market would be high. As a result, the difference between bid and ask prices for your Notes in any secondary market could be substantial. If you sell your Notes before an automatic call or the Maturity Date, you may have to do so at a substantial discount from the public offering price irrespective of the level of the Reference Asset at such time, and as a result, you may suffer substantial losses.

If the Level of the Reference Asset Changes, the Market Value of Your Notes May Not Change in the Same Manner.

There Are Potential Conflicts of Interest Between You and the Calculation Agent.

The Calculation Agent will, among other things, determine whether the Call Premium is payable on the Call Payment Date and the Payment at Maturity, if any, on the Notes. We will serve as the Calculation Agent and may appoint a different Calculation Agent after the Issue Date without notice to you. The Calculation Agent will exercise its judgment when performing its functions. For example, the Calculation Agent may have to determine whether a Market Disruption Event affecting the Reference Asset has occurred, which may, in turn, depend on the Calculation Agent’s judgment as to whether the event has materially interfered with our ability or the ability of one of our affiliates to unwind our hedge positions. Because this determination by the Calculation Agent may affect the return on the Notes, the Calculation Agent may have a conflict of interest if it needs to make a determination of this kind. For additional information as to the Calculation Agent’s role, see “General Terms of the Notes — Role of Calculation Agent” in the product supplement.

The Review Date, Valuation Date and the Related Payment Dates are Subject to Market Disruption Events and Postponement.

The Review Date and Valuation Date, and therefore the Call Payment Date and Maturity Date, are subject to postponement as described herein and in the product supplement due to the occurrence of one or more Market Disruption Events, which, among other events, may occur if the Calculation Agent determines that an event materially interferes with our ability or the ability of any of our affiliates’ to maintain or unwind all or a material portion of a hedge with respect to the Notes that we or our affiliates have effected or may effect or to effect trading in the Reference Asset generally. For a description of what constitutes a Market Disruption Event as well as the consequences of that Market Disruption Event, see “General Terms of the Notes — Market Disruption Events” in the product supplement.

Trading and Business Activities by TD or its Affiliates May Adversely Affect the Market Value of, and Return on, the Notes.

We, the Agent and/or one or more of our other affiliates may hedge our obligations under the Notes by purchasing securities, futures, options or other derivative instruments with returns linked or related to changes in the level of the Reference Asset or one or more Reference Asset Constituents, and we may adjust these hedges by, among other things, purchasing or selling at any time any of the foregoing assets. It is possible that we and/or one or more of our affiliates could receive substantial returns from these hedging activities while the market value of, and return on, the Notes declines. We and/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 or one or more Reference Asset Constituents.

These trading activities may present a conflict between the holders’ interest in the Notes and the interests we and/or our affiliates will have in our or their proprietary accounts, in facilitating transactions, including options and other derivatives transactions, for our and/or their customers’ accounts and in accounts under our and/or their management. These trading activities could be adverse to the interests of the holders of the Notes.

We, the Agent and/or another of our affiliates may, at present or in the future, engage in business with the Reference Asset Constituent Issuers, such as making loans or providing investment banking and merger and acquisition advisory services. These business activities may present a conflict between our and/or one or more of our affiliates’ (including the Agent’s) obligations and your interests as a holder of the Notes. Moreover, we, the Agent and/or another of our affiliates may have published, and in the future expect to publish, research reports with respect to the Reference Asset or one or more Reference Asset Constituent Issuers. This research is modified from time to time without notice and may express opinions or provide recommendations that are inconsistent with purchasing or holding the Notes. Any of these activities by us, the Agent and/or another of our affiliates may affect the level of the Reference Asset and, therefore, the market value of, and return on, the Notes.

Risks Relating to General Credit Characteristics

Investors Are Subject to TD’s Credit Risk, and TD’s Credit Ratings and Credit Spreads May Adversely Affect the Market Value of the Notes.

Although the return on the Notes will be based on the performance of the Reference Asset, the payment of any amount due on the Notes is subject to TD’s credit risk. The Notes are TD’s senior unsecured debt obligations. Investors are dependent on TD’s ability to pay all amounts due on the Notes and, therefore, investors are subject to the credit risk of TD and to changes in the market’s view of TD’s creditworthiness. Any decrease in TD’s credit ratings or increase in the credit spreads charged by the market for taking TD’s credit risk is likely to adversely affect the market value of the Notes. If TD becomes unable to meet its financial obligations as they become due, investors may not receive any amount due under the terms of the Notes.

Risks Relating to Canadian and U.S. Federal Income Taxation

Significant Aspects of the Tax Treatment of the Notes Are Uncertain.

Significant aspects of the U.S. tax treatment of the Notes are uncertain. You should consult your tax advisor about your tax situation and should read carefully the sections entitled “Material U.S. Federal Income Tax Consequences” herein and in the product supplement. You should consult your tax advisors as to the tax consequences of your investment in the Notes.

For a discussion of the Canadian federal income tax consequences of investing in the Notes, please see the discussion in the product supplement under “Supplemental Discussion of Canadian Tax Consequences” and the further discussion herein under “Additional Terms”.

If you are not a Non-resident Holder (as that term is defined in the prospectus) for Canadian federal income tax purposes or if you acquire the Notes in the secondary market, you should consult your tax advisors as to the consequences of acquiring, holding and disposing of the Notes and receiving the payments that might be due under the Notes.

The information reflects the policies of, and is subject to change by, the Index Sponsor. The Index Sponsor, which owns the copyright and all other rights to the Reference Asset, has no obligation to continue to publish, and may discontinue publication of, the Reference Asset. None of the websites referenced in the Reference Asset description below, or any materials included in those websites, are incorporated by reference into this document or any document incorporated herein by reference.

The graph below sets forth the information relating to the historical performance of the Reference Asset for the period specified. We obtained the information regarding the historical performance of the Reference Asset in the graph below from Bloomberg Professional^® service (“Bloomberg”).

We have not independently verified the accuracy or completeness of the information obtained from Bloomberg. The historical performance of the Reference Asset should not be taken as an indication of its future performance, and no assurance can be given as to the Closing Level or Final Level of the Reference Asset on any date. We cannot give you any assurance that the performance of the Reference Asset will result in a positive return on your initial investment.

The S&P 500^® Index (the “SPX”) includes a representative sample of 500 companies in leading industries of the U.S. economy. The 500 companies are not the 500 largest companies listed on the New York Stock Exchange (“NYSE”) and not all 500 companies are listed on the NYSE. The Index Sponsor, S&P Dow Jones Indices LLC, chooses companies for inclusion in the SPX with an aim of achieving a distribution by broad industry groupings that approximates the distribution of these groupings in the common stock population of the U.S. domiciled equity market. Although the SPX contains 500 constituent companies, at any one time it may contain greater than 500 constituent trading lines since some companies included in the SPX prior to July 31, 2017 may be represented by multiple share class lines in the SPX. The SPX is calculated, maintained and published by the Index Sponsor and is part of the S&P Dow Jones Indices family of indices. Additional information (including sectors and sector weights and top constituents) is available on the following website: spglobal.com/spdji/en/indices/equity/sp-500. We are not incorporating by reference the websites or any material they include in this document or any document incorporated herein by reference.

The Index Sponsor 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 the S&P Index Committee. Relevant criteria for additions to the SPX that are employed by the Index Sponsor include: the company proposed for addition should have an unadjusted company market capitalization of $18.0 billion or more and a security level float-adjusted market capitalization of at least 50% of such threshold (for spin-offs, eligibility is determined using when-issued prices, if available); the float-adjusted liquidity ratio of the stock (defined as the annual dollar value traded divided by the float-adjusted market capitalization) should be greater than or equal to 0.75 at the time of the addition to the SPX and the stock should trade a minimum of 250,000 shares in each of the six months leading up to the evaluation date (current constituents have no minimum requirement), where the annual dollar value traded is calculated as the average closing price multiplied by the historical volume over the 365 calendar days prior to the evaluation date (reduced to the available trading period for IPOs, spinoffs or public companies considered to be U.S. domiciled for index purposes that do not have 365 calendar days of trading history on a U.S. exchange); the company must be a U.S.-domiciled company (characterized as a company that satisfies U.S. Securities Exchange Act’s periodic reporting obligations by filing certain required forms for domestic issuers (e.g., Form 10-K annual reports, Form 10-Q quarterly reports and Form 8-K current reports, among others) and with a primary listing of the common stock on the NYSE, NYSE Arca, NYSE American (formerly NYSE MKT), Nasdaq Global Select Market, Nasdaq Global Market, Nasdaq Capital Market, Cboe BZX (formerly Bats BZX), Cboe BYX (formerly Bats BYX), Cboe EDGA (formerly Bats EDGA) or Cboe EDGX (formerly Bats EDGX) (each, an “eligible exchange”)); the proposed constituent has an investable weight factor (“IWF”) of 10% or more; the inclusion of the company will contribute to sector balance in the SPX relative to sector balance in the market in the relevant market capitalization range; financial viability (the sum of the most recent four consecutive quarters’ Generally Accepted Accounting Principles (GAAP) earnings (net income excluding discontinued operations) should be positive as should the most recent quarter); and, for IPOs, the company must be traded on an eligible exchange for at least twelve months (for former SPACs, S&P considers the de-SPAC transaction to be an event equivalent to an IPO, and 12 months of trading post the de-SPAC event are required before a former SPAC can be considered for inclusion in the SPX; spin-offs or in-specie distributions from existing constituents do not need to be traded on an eligible exchange for twelve months prior to their inclusion in the SPX). In addition, constituents of the S&P MidCap 400^® Index and the S&P SmallCap 600^® Index can be added to the SPX provided they meet the unadjusted company level market capitalization eligibility criteria for the SPX. Migrations from the S&P MidCap 400^® Index or the S&P SmallCap 600^® Index do not need to meet the financial viability, liquidity, or 50% of the SPX’s unadjusted company level minimum market capitalization threshold criteria. Further, constituents of the S&P Total Market Index Ex S&P Composite 1500 (which includes all eligible U.S. common equities except for those included in the SPX, the S&P MidCap 400^® Index and the S&P SmallCap 600^® Index) that acquire a constituent of the SPX, the S&P MidCap 400^® Index or the S&P SmallCap 600^® Index that do not fully meet all of the eligibility criteria may still be added to the SPX at the discretion of the S&P Index Committee if the merger consideration includes the acquiring company issuing stock to target company shareholders, and the S&P Index Committee determines that the addition could minimize turnover and enhance the representativeness of the SPX as a market benchmark. Certain types of organizational structures and securities are always excluded, including, but not limited to, business development companies (BDCs), limited partnerships, master limited partnerships, limited liability companies (LLCs), OTC bulletin board issues, closed-end funds, ETFs, ETNs, royalty trusts, tracking stocks, special purpose acquisition companies (SPACs), preferred stock and convertible preferred stock, unit trusts, equity warrants, convertible bonds, investment trusts, rights and American depositary receipts. SPX constituents are deleted from the SPX when they are involved in mergers, acquisitions or significant restructurings such that they

For constituents included in the SPX prior to July 31, 2017, all publicly listed multiple share class lines are included separately in the SPX, subject to, in the case of any such share class line, that share class line satisfying the liquidity and float criteria discussed above and subject to certain exceptions. It is possible that one listed share class line of a company may be included in the SPX while a second listed share class line of the same company is excluded. For companies that issue a second publicly traded share class to SPX share class holders, the newly issued share class line is considered for inclusion if the event is mandatory and the market capitalization of the distributed class is not considered to be de minimis.

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. Constituents of the SPX prior to July 31, 2017 with multiple share class lines will be grandfathered in and continue to be included in the SPX. If a SPX constituent reorganizes into a multiple share class line structure, that company will be reviewed for continued inclusion in the SPX at the discretion of the S&P Index Committee.

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

The SPX is also sometimes called a “base-weighted aggregative index” because of its use of a divisor. The “divisor” is a value calculated by the Index Sponsor that is intended to maintain conformity in SPX levels over time and is adjusted for all changes in the SPX constituents’ share capital after the “base date” as described below. The level of the SPX reflects the total market value of all SPX constituents relative to the SPX’s base date of 1941-43.

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. The Index Sponsor seeks to exclude shares held by long-term, strategic shareholders concerned with the control of a company, a group that generally includes the following: officers and directors and related individuals whose holdings are publicly disclosed, private equity, venture capital, special equity firms, asset managers and insurance companies with board of director representation, publicly traded companies that hold shares in another company, holders of restricted shares (except for shares held as part of a lock-up agreement), company-sponsored employee share plans/trusts, defined contribution plans/savings, investment plans, foundations or family trusts associated with the company, government entities at all levels (except government retirement or pension funds), sovereign wealth funds and any individual person listed as a 5% or greater stakeholder in a company as reported in regulatory filings (collectively, “strategic holders”). To this end, the Index Sponsor excludes all share-holdings (other than depositary banks, pension funds (including government pension and retirement funds), mutual funds, ETF providers, investment funds, asset managers that do not have direct board of director representation (including stakeholders who may have the right to appoint a board of director member but choose not to do so, stakeholders who have exercised a right to appoint a board of director “observer” even if that observer is employed by the stakeholder and stakeholders who have exercised a right to appoint an independent director who is not employed by the stakeholder), investment funds of insurance companies and independent foundations not associated with the company) with a position greater than 5% of the outstanding shares of a company from the float-adjusted share count to be used in SPX calculations.

The exclusion is accomplished by calculating an IWF for each SPX constituent that is part of the numerator of the float-adjusted index fraction described above:

where available float shares is defined as total shares outstanding less shares held by strategic holders. 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.

In order to keep the SPX comparable over time the Index Sponsor engages in an index maintenance process. The SPX maintenance process involves changing the constituents as discussed above, and also 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. 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 to ensure the SPX continues to achieve the stated objective, and that the data and methodology remain effective. 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.

Divisor Adjustments

The two types of adjustments primarily used by the Index Sponsor are divisor adjustments and adjustments to the number of shares (including float adjustments) used to calculate the SPX. Set forth below under “Adjustments for Corporate Actions” is a table of certain corporate events and their resulting effect on the divisor and the share count. If a corporate event requires an adjustment to the divisor, that event has the effect of altering the market value of the affected SPX constituent and consequently of altering the aggregate market value of the SPX constituents following the event. In order that the level of the SPX not be affected by the altered market value (which could be an increase or decrease) of the affected SPX constituent, the Index Sponsor generally derives a new divisor by dividing the post-event market value of the SPX constituents by the pre-event SPX level, which has the effect of reducing the SPX’s post-event level to the pre-event level.

Changes to the Number of Shares of a Constituent

The index maintenance process also involves tracking the changes in the number of shares included for each of the index companies. Changes as a result of mandatory events, such as mergers or acquisition driven share/IWF changes, stock splits and mandatory distributions are not subject to a minimum threshold for implementation and are implemented when the transaction occurs. At the Index Sponsor’s discretion, however, de minimis merger and acquisition changes may be accumulated and implemented with the updates made with the quarterly share updates as described below. Material share/IWF changes resulting from certain non-mandatory corporate actions follow the accelerated implementation rule. Non-material share/IWF changes are implemented quarterly.

1. Public offerings. Public offerings of new company-issued shares and/or existing shares offered by selling shareholders, including block sales and spot secondaries, will be eligible for accelerated implementation treatment if the size of the event meets the materiality threshold criteria:

For public offerings that involve a concurrent combination of new company shares and existing shares offered by selling shareholders, both events are implemented if either of the public offerings represent at least 5% of total shares and $150 million. Any concurrent share repurchase by the affected company will also be included in the implementation.

2. Dutch Auctions, self-tender offer buybacks, and split-off exchange offers. These nonmandatory corporate action types will be eligible for accelerated implementation treatment regardless of size once the final results are publicly announced and verified by S&P.

For companies with multiple share class lines, the criteria specified above apply to each individual multiple share class line rather than total company shares.

Exception to the Accelerated Implementation Rule

For non-mandatory corporate actions subject to the accelerated implementation rule with a size of at least US $1 billion, S&P will apply the share change, and any resulting IWF change, using the latest share and ownership information publicly available at the time of the announcement, even if the offering size is below the 5% threshold. This exception ensures that very large events are recognized in a timely manner using the latest available information.

Any non-fully paid or non-fully settled offering such as forward sales agreements are not eligible for accelerated implementation. Share updates resulting from completion of subscription receipts terms or the settlement of forward sale agreements are updated at a future quarterly share rebalancing.

All non-mandatory events not covered by the accelerated implementation rule (including but not limited to private placements, acquisition of private companies, and conversion of non-index share lines) will be implemented quarterly coinciding with the third Friday of the third month in each calendar quarter. In addition, events that were not implemented under the accelerated implementation rule but were found to have been eligible, (e.g. due to lack of publicly available information at the time of the event) are implemented as part of a quarterly rebalancing.

For accelerated implementation, the Index Sponsor will generally provide two (2) business days’ notice for all non-U.S. listed stocks and U.S. listed depositary receipts, and one (1) business days’ notice for all non-depositary receipt U.S. listed stocks.

Accelerated implementation for events less than $1 billion will include an adjustment to the company’s IWF only to the extent that such an IWF change helps the new float share total mimic the shares available in the offering. To minimize unnecessary turnover, these IWF changes do not need to meet any minimum threshold requirement for implementation. Any IWF change resulting in an IWF of 0.96 or greater is rounded up to 1.00 at the next annual IWF review.

IWF changes will only be made at the quarterly review if the change represents at least 5% of total current shares outstanding and is related to a single corporate action that did not qualify for the accelerated implementation rule, regardless of whether there is an associated share change.

Quarterly share change events resulting from the conversion of derivative securities, acquisitions of private companies, or acquisitions of non-index companies that do not trade on a major exchange are considered to be available to investors unless there is explicit information stating that the new owner is a strategic holder.

A reference date, after the market close five weeks prior to the third Friday in March, June, September, and December, is the cutoff for publicly available information used for quarterly shares outstanding and IWF changes. All shares outstanding and ownership information contained in public filings and/or official sources dated on or before the reference date are included in that quarter’s update. In addition, there is a freeze period on a quarterly basis for any changes that result from the accelerated implementation rules.

Pro-forma files for float-adjusted market capitalization indices are generally released after the market close on the first Friday, two weeks prior to the rebalancing effective date. Pro-forma files for capped and alternatively weighted indices are generally released after the market close on the second Friday, one week prior to the rebalancing effective date. For illustration purposes, if rebalancing pro-forma files are scheduled to be released on Friday, March 5, the share/IWF freeze period will begin after the close of trading on Tuesday, March 9 and will end after the close of trading the following Friday, March 19 (i.e. the third Friday of the rebalancing month).

During the share/IWF freeze period, shares and IWFs are not changed and the accelerated implementation rule is suspended, except for mandatory corporate action events (such as merger activity, stock splits, and rights offerings). The suspension includes all changes that qualify for accelerated implementation and would typically be announced or effective during the share/IWF freeze period. At the end of the freeze period all suspended changes will be announced on the third Friday of the rebalancing month and implemented five business days after the quarterly rebalancing effective date.

Adjustments for Corporate Actions

There is a large range of corporate actions that may affect companies included in the SPX. Certain corporate actions require the Index Sponsor to recalculate the share count or the float adjustment or to make an adjustment to the divisor to prevent the level 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.

Spin-Offs

As a general policy, a spin-off security is added to the SPX on the ex-date at a price of zero (with no divisor adjustment) and will remain in the SPX for at least one trading day. The spin-off security will remain in the SPX if it meets all eligibility criteria. If the spin-off security is determined ineligible to remain in the SPX, it will generally be removed after at least one day of regular way trading (with a divisor adjustment). The weight of the spin-off being deleted is reinvested across all the SPX constituents proportionately such that the relative weights of all SPX constituents are unchanged. The net change in SPX market capitalization will cause a divisor change.

Companies that are spun off from a SPX constituent do not need to meet the eligibility criteria for new constituents, but they should be considered U.S. domiciled for SPX purposes. At the discretion of the S&P Index Committee, a spin-off company may be retained in the SPX if the S&P Index Committee determines it has a total market capitalization representative of the SPX. If the spin-off company’s estimated market capitalization is below the minimum unadjusted company market capitalization for the SPX but there are other SPX constituents that have a significantly lower total market capitalization than the spin-off company, the S&P Index Committee may decide to retain the spin-off company in the SPX.

Several additional types of corporate actions, and their related treatment, are listed in the table below.

Any company that is removed from the SPX, the S&P MidCap 400^® Index or the S&P SmallCap 600^® Index must wait a minimum of one year from its removal date before being reconsidered as a replacement candidate for the SPX.

The Index Sponsor reserves the right to recalculate and republish the SPX at its discretion in the event one of the following issues has occurred: (1) incorrect or revised closing price of one or more constituent securities; (2) missed or misapplied corporate action; (3) incorrect application of SPX methodology; (4) late announcement of a corporate action; or (5) incorrect calculation or data entry error. The decision to recalculate the SPX is made at the discretion of the index manager and/or index committee, as further discussed below. The potential market impact or disruption resulting from a recalculation is considered when making any such decision. In the event of an incorrect closing price, a missed or misapplied corporate action, a late announcement of a corporate action, or an incorrect calculation or data entry error that is discovered within two trading days of its occurrence, generally the SPX is recalculated. In the event any such event is discovered beyond the two trading day period, the index committee shall decide whether the SPX should be recalculated. In the event of an incorrect application of the methodology that results in the incorrect composition and/or weighting of SPX constituents, the index committee shall determine whether or not to recalculate the SPX following specified guidelines. In the event that the SPX is recalculated, it shall be done within a reasonable timeframe following the detection and review of the issue.

Closing levels for the SPX are calculated by the Index Sponsor based on the closing price of the individual constituents of the SPX as set by their primary exchange. Closing prices are received by the Index Sponsor from one of its third-party vendors and verified by comparing them with prices from an alternative vendor. The vendors receive the closing price from the primary exchanges. Real-time intraday prices are calculated similarly without a second verification. Official end-of-day calculations are based on each stock’s primary market closing price. Prices used for the calculation of real time SPX levels are based on the “Consolidated Tape”. The Consolidated Tape is an aggregation of trades for each constituent over all regional exchanges and trading venues and includes the primary exchange. If there is a failure or interruption on one or more exchanges, real-time calculations will continue as long as the “Consolidated Tape” is operational.

An unexpected market/exchange closure occurs when a market/exchange fully or partially fails to open or trading is temporarily halted. This can apply to a single exchange or to a market as a whole, when all of the primary exchanges are closed and/or not trading. Unexpected market/exchange closures are usually due to unforeseen circumstances, such as natural disasters, inclement weather, outages, or other events.

If all major exchanges fail to open or unexpectedly halt trading intraday due to unforeseen circumstances, the Index Sponsor will take the following actions:

Material U.S. Federal Income Tax Consequences

The U.S. federal income tax consequences of your investment in the Notes are uncertain. No statutory, regulatory, judicial or administrative authority directly discusses how the Notes should be treated for U.S. federal income tax purposes. Some of these tax consequences are summarized below, but we urge you to read the more detailed discussion under “Material U.S. Federal Income Tax Consequences” in the product supplement and discuss the tax consequences of your particular situation with your tax advisor. This discussion is based upon the U.S. Internal Revenue Code of 1986, as amended (the “Code”), final, temporary and proposed U.S. Department of the Treasury (the “Treasury”) regulations, rulings and decisions, in each case, as available and in effect as of the date hereof, all of which are subject to change, possibly with retroactive effect. Tax consequences under state, local and non-U.S. laws are not addressed herein. No ruling from the U.S. Internal Revenue Service (the “IRS”) has been sought as to the U.S. federal income tax consequences of your investment in the Notes, and the following discussion is not binding on the IRS. Except as discussed under the heading “Non-U.S. Holders”, this discussion is applicable only to a U.S. holder that acquires Notes upon initial issuance and holds its Notes as a capital asset for U.S. federal income tax purposes.

Based on certain factual representations received from us, our special U.S. tax counsel, Fried, Frank, Harris, Shriver & Jacobson LLP, is of the opinion that it would be reasonable to treat your Notes in the manner described above. However, because there is no authority that specifically addresses the tax treatment of the Notes, it is possible that your Notes could alternatively be treated for tax purposes as a single contingent payment debt instrument, or pursuant to some other characterization, such that the timing and character of your income from the Notes could differ materially and adversely from the treatment described above, as described further under “Material U.S. Federal Income Tax Consequences — Alternative Treatments” in the product supplement.

Specified Foreign Financial Assets. U.S. holders may be subject to reporting obligations with respect to their Notes if they do not hold their Notes in an account maintained by a financial institution and the aggregate value of their Notes and certain other “specified foreign financial assets” (applying certain attribution rules) exceeds an applicable threshold. Significant penalties can apply if a U.S. holder is required to disclose its Notes and fails to do so.

Because of the uncertainty regarding the application of the 30% withholding tax on dividend equivalents to the Notes, you are urged to consult your tax advisor regarding the potential application of Section 871(m) of the Code and the 30% withholding tax to an investment in the Notes.

Foreign Account Tax Compliance Act. The Foreign Account Tax Compliance Act (“FATCA”) was enacted on March 18, 2010, and imposes a 30% U.S. withholding tax on “withholdable payments” (i.e., certain U.S.-source payments, including interest (and original issue discount), dividends, other fixed or determinable annual or periodical income, and the gross proceeds from a disposition of property of a type that can produce U.S.-source interest or dividends) and “passthru payments” (i.e., certain payments attributable to withholdable payments) made to certain foreign financial institutions (and certain of their affiliates) unless the payee foreign financial institution agrees (or is required), among other things, to disclose the identity of any U.S. individual with an account at the institution (or the relevant affiliate) and to annually report certain information about such account. FATCA also requires withholding agents making withholdable payments to certain foreign entities that do not disclose the name, address, and taxpayer identification number of any substantial U.S. owners (or do not certify that they do not have any substantial U.S. owners) to withhold tax at a rate of 30%. Under certain circumstances, a holder may be eligible for refunds or credits of such taxes.

Investors should consult their tax advisors about the application of FATCA, in particular if they may be classified as financial institutions (or if they hold their Notes through a foreign entity) under the FATCA rules.

Supplemental Plan of Distribution (Conflicts of Interest)

We expect to deliver the Notes against payment therefor on the Issue Date, which is expected to be the third DTC settlement day following the Pricing Date. Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in one DTC settlement day (“T+1”), unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes in the secondary market on any date prior to one DTC settlement day before delivery of the Notes will be required, by virtue of the fact that each Note initially will settle in three DTC settlement days (“T+3”), to specify alternative settlement arrangements to prevent a failed settlement of the secondary market trade.

Conflicts of Interest. TDS is an affiliate of TD and, as such, has a “conflict of interest” in this offering within the meaning of Financial Industry Regulatory Authority, Inc. (“FINRA”) Rule 5121. In addition, TD will receive the net proceeds from the initial public offering of the Notes, thus creating an additional conflict of interest within the meaning of FINRA Rule 5121. This offering of the Notes will be conducted in compliance with the provisions of FINRA Rule 5121. In accordance with FINRA Rule 5121, neither TDS nor any other affiliated agent of ours is permitted to sell the Notes in this offering to an account over which it exercises discretionary authority without the prior specific written approval of the account holder.

Prohibition of Sales to EEA and United Kingdom Retail Investors

The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom (the “UK”). For these purposes, a retail investor in the UK means a person who is one (or more) of: (i) a retail client as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018, subject to amendments made by the Markets in Financial Instruments (Amendment) (EU Exit) Regulations 2018 (SI 2018/1403), as may be amended or superseded from time to time (the “EUWA”); (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (the “FSMA”) and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of UK domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of the Prospectus Regulation as it forms part of domestic law by virtue of the EUWA (“UK Prospectus Regulation”). Consequently, no key information document required by the PRIIPs Regulation as it forms part of UK domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.
