Investing in the Notes involves a number of risks. See “Selected Risk Considerations” beginning on page P-6 of this pricing supplement and “Risk Factors” in the accompanying prospectus, prospectus supplement and product supplement.

None of the Securities and Exchange Commission (the “SEC”), any state securities commission or any other regulatory body has approved or disapproved of the Notes or passed upon the adequacy or accuracy of this pricing supplement. Any representation to the contrary is a criminal offense. The Notes will not constitute deposits insured by the Canada Deposit Insurance Corporation, the U.S. Federal Deposit Insurance Corporation or any other Canadian or U.S. governmental agency or instrumentality. The Notes are not bail-inable notes and are not subject to conversion into our common shares under subsection 39.2(2.3) of the Canada Deposit Insurance Corporation Act.

⁽¹⁾ We or one of our affiliates may pay varying selling concessions of up to $30.00 per $1,000 principal amount of Notes in connection with the distribution of the Notes to other registered broker-dealers. Certain dealers who purchase the Notes for sale to certain fee-based advisory accounts may forgo some or all of their underwriting discount or selling concessions. The public offering price for investors purchasing the Notes in these accounts may be between $970.00 and $1,000.00 per $1,000 principal amount of Notes. In addition, we or one of our affiliates may pay a broker-dealer that is not affiliated with us a referral fee of up to $10.00 per $1,000 principal amount of Notes. See “Supplemental Plan of Distribution (Conflicts of Interest)” below.

The initial estimated value of the Notes determined by us as of the Trade Date, which we refer to as the initial estimated value, is $945.10 per $1,000 principal amount of Notes and is less than the public offering price of the Notes. The market value of the Notes at any time will reflect many factors, cannot be predicted with accuracy and may be less than this amount. We describe the determination of the initial estimated value in more detail below.

SELECTED RISK CONSIDERATIONS

An investment in the Notes involves significant risks. We urge you to consult your investment, legal, tax, accounting and other advisers before you invest in the Notes. Some of the risks that apply to an investment in the Notes are summarized below, but we urge you to read also the “Risk Factors” sections of the accompanying prospectus, prospectus supplement and product supplement. You should not purchase the Notes unless you understand and can bear the risks of investing in the Notes.

Risks Relating to the Terms and Structure of the Notes

Risks Relating to the Initial Estimated Value of the Notes and the Secondary Market for the Notes

securities exchange. RBCCM and our other affiliates may make a market for the Notes; however, they are not required to do so and, if they choose to do so, may stop any market-making activities at any time. Because other dealers are not likely to make a secondary market for the Notes, the price at which you may be able to trade your Notes is likely to depend on the price, if any, at which RBCCM or any of our other affiliates is willing to buy the Notes. Even if a secondary market for the Notes develops, it may not provide enough liquidity to allow you to easily trade or sell the Notes. 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 maturity, you may have to do so at a substantial discount from the price that you paid for them, and as a result, you may suffer significant losses. The Notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your Notes to maturity.

The value of the Notes at any time after the Trade Date will vary based on many factors, including changes in market conditions, and cannot be predicted with accuracy. As a result, the actual value you would receive if you sold the Notes in any secondary market, if any, should be expected to differ materially from the initial estimated value of the Notes.

Risks Relating to Conflicts of Interest and Our Trading Activities

payments on the Notes. In making these determinations, the Calculation Agent may be required to make discretionary judgments, including those described under “—Risks Relating to the Basket Underliers” below. In making these discretionary judgments, the economic interests of the Calculation Agent are potentially adverse to your interests as an investor in the Notes, and any of these determinations may adversely affect any payments on the Notes. The Calculation Agent will have no obligation to consider your interests as an investor in the Notes in making any determinations with respect to the Notes.

Risks Relating to the Basket Underliers

The performance of a Fund may diverge significantly from the performance of its Underlying Index due to differences in trading hours between that Fund and the securities composing its Underlying Index or other circumstances. During periods of market volatility, the component securities held by a Fund may be unavailable in the secondary market, market participants may be unable to calculate accurately the intraday net asset value per share of that Fund and the liquidity of that Fund may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares in a Fund. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares of a Fund. As a result, under these circumstances, the market value of a Fund may vary substantially from the net asset value per share of that Fund.

In general, fixed-income instruments are significantly affected by changes in current market interest rates. As interest rates rise, the prices of fixed-income instruments are likely to decrease, and as interest rate fall, the price of fixed-income securities are likely to increase. Securities with longer durations tend to be especially sensitive to interest rate changes, usually making them more volatile than securities with shorter durations. As a result, rising interest rates may cause the value of the long-dated bonds underlying a Fund to decline, possibly significantly, which would adversely affect the value of the Notes.

In addition, the prices of the bonds underlying a Fund are significantly influenced by the creditworthiness of their issuers. The bonds underlying a Fund may have their credit ratings downgraded, or their credit spreads may widen significantly. Following a ratings downgrade or the widening of credit spreads, the bonds underlying a Fund may suffer significant and rapid price declines, which would adversely affect the value of the Notes.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

You should review carefully the section in the accompanying product supplement entitled “United States Federal Income Tax Considerations.” The following discussion, when read in combination with that section, constitutes the full opinion of our counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of the Notes.

Generally, this discussion assumes that you purchased the Notes for cash in the original issuance at the stated issue price and does not address other circumstances specific to you, including consequences that may arise due to any other investments relating to the Basket Underliers. You should consult your tax adviser regarding the effect any such circumstances may have on the U.S. federal income tax consequences of your ownership of a Note.

We intend to treat the Notes for U.S. federal income tax purposes as contingent payment debt instruments, or “CPDIs,” as described in “United States Federal Income Tax Considerations—Tax Consequences to U.S. Holders—Notes Treated as Debt Instruments—Notes Treated as Contingent Payment Debt Instruments” in the accompanying product supplement. In the opinion of our counsel, which is based on current market conditions, this treatment of the Notes is reasonable under current law. Assuming this treatment is respected, regardless of your method of accounting for U.S. federal income tax purposes, you generally will be required to accrue interest income in each year on a constant yield to maturity basis at the “comparable yield,” as determined by us, adjusted upward or downward to reflect the difference, if any, between the actual and projected payments on the Notes during the year. Upon a taxable disposition of a Note, you generally will recognize taxable income or loss equal to the difference between the amount received and your tax basis in the Notes. You generally must treat any income realized as interest income and any loss as ordinary loss to the extent of previous interest inclusions, and the balance as capital loss, the deductibility of which is subject to limitations.

After the original issue date, you may obtain the comparable yield and the projected payment schedule by requesting them from RBCCM at 1-877-688-2301.

Neither the comparable yield nor the projected payment schedule constitutes a representation by us regarding the actual amount(s) that we will pay on the Notes.

Non-U.S. Holders. If you are a Non-U.S. Holder, please also read the section entitled “United States Federal Income Tax Considerations—Tax Consequences to Non-U.S. Holders— Notes Treated as Debt Instruments” in the accompanying product supplement.

As discussed under “United States Federal Income Tax Considerations—Tax Consequences to Non-U.S. Holders—Dividend Equivalents under Section 871(m) of the Code” in the accompanying product supplement, Section 871(m) of the Internal Revenue Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities. The Treasury regulations, as modified by an Internal Revenue Service (the “IRS”) notice, exempt financial instruments issued prior to January 1, 2027 that do not have a “delta” of one. Based on certain determinations made by us, our counsel is of the opinion that Section 871(m) should not apply to the Notes with regard to Non-U.S. Holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination.

We will not be required to pay any additional amounts with respect to U.S. federal withholding taxes.

You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the Notes, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

The Notes are offered initially to investors at a purchase price equal to par, except with respect to certain accounts as indicated on the cover page of this pricing supplement. We or one of our affiliates may pay the underwriting discount and may pay a broker-dealer that is not affiliated with us a referral fee, in each case as set forth on the cover page of this pricing supplement.

The value of the Notes shown on your account statement may be based on RBCCM’s estimate of the value of the Notes if RBCCM or another of our affiliates were to make a market in the Notes (which it is not obligated to do). That estimate will be based on the price that RBCCM may pay for the Notes in light of then-prevailing market conditions, our creditworthiness and transaction costs. For a period of approximately nine months after the Issue Date, the value of the Notes that may be shown on your account statement may be higher than RBCCM’s estimated value of the Notes at that time. This is because the estimated value of the Notes will not include the underwriting discount, the referral fee or our hedging costs and profits; however, the value of the Notes shown on your account statement during that period may initially be a higher amount, reflecting the addition of the underwriting discount, the referral fee and our estimated costs and profits from hedging the Notes. This excess is expected to decrease over time until the end of this period. After this period, if RBCCM repurchases your Notes, it expects to do so at prices that reflect their estimated value.

RBCCM or another of its affiliates or agents may use this pricing supplement in the initial sale of the Notes. In addition, RBCCM or another of our affiliates may use this pricing supplement in a market-making transaction in the Notes after their initial sale. Unless we or our agent informs the purchaser otherwise in the confirmation of sale, this pricing supplement is being used in a market-making transaction.

For additional information about the settlement cycle of the Notes, see “Plan of Distribution” in the accompanying prospectus. For additional information as to the relationship between us and RBCCM, see the section “Plan of Distribution—Conflicts of Interest” in the accompanying prospectus.

STRUCTURING THE NOTES

The Notes are our debt securities. As is the case for all of our debt securities, including our structured notes, the economic terms of the Notes reflect our actual or perceived creditworthiness. In addition, because structured notes result in increased operational, funding and liability management costs to us, we typically borrow the funds under structured notes at a rate that is lower than the rate that we might pay for a conventional fixed or floating rate debt security of comparable maturity. The lower internal funding rate, the underwriting discount, the referral fee and the hedging-related costs relating to the Notes reduce the economic terms of the Notes to you and result in the initial estimated value for the Notes being less than their public offering price. Unlike the initial estimated value, any value of the Notes determined for purposes of a secondary market transaction may be based on a secondary market rate, which may result in a lower value for the Notes than if our initial internal funding rate were used.

In order to satisfy our payment obligations under the Notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with RBCCM and/or one of our other subsidiaries. The terms of these hedging arrangements take into account a number of factors, including our creditworthiness, interest rate movements, volatility and the tenor of the Notes. The economic terms of the Notes and the initial estimated value depend in part on the terms of these hedging arrangements.

See “Selected Risk Considerations—Risks Relating to the Initial Estimated Value of the Notes and the Secondary Market for the Notes—The Initial Estimated Value of the Notes Is Less Than the Public Offering Price” above.

VALIDITY OF THE NOTES

In the opinion of Norton Rose Fulbright Canada LLP, as Canadian counsel to the Bank, the issue and sale of the Notes has been duly authorized by all necessary corporate action of the Bank in conformity with the indenture, and when the Notes have been duly executed, authenticated and issued in accordance with the indenture and delivered against payment therefor, the Notes will be validly issued and, to the extent validity of the Notes is a matter governed by the laws of the

Province of Ontario or Québec, or the federal laws of Canada applicable therein, will be valid obligations of the Bank, subject to the following limitations: (i) the enforceability of the indenture may be limited by the Canada Deposit Insurance Corporation Act (Canada), the Winding-up and Restructuring Act (Canada) and bankruptcy, insolvency, reorganization, receivership, moratorium, arrangement or winding-up laws or other similar laws of general application affecting the enforcement of creditors’ rights generally; (ii) the enforceability of the indenture is subject to general equitable principles, including the principle that the availability of equitable remedies, such as specific performance and injunction, may only be granted at the discretion of a court of competent jurisdiction; (iii) under applicable limitations statutes generally, including that the enforceability of the indenture will be subject to the limitations contained in the Limitations Act, 2002 (Ontario), and such counsel expresses no opinion as to whether a court may find any provision of the indenture to be unenforceable as an attempt to vary or exclude a limitation period under such applicable limitations statutes; (iv) rights to indemnity and contribution under the Notes or the indenture which may be limited by applicable law; and (v) courts in Canada are precluded from giving a judgment in any currency other than the lawful money of Canada and such judgment may be based on a rate of exchange in existence on a day other than the day of payment, as prescribed by the Currency Act (Canada). This opinion is given as of the date hereof and is limited to the laws of the Provinces of Ontario and Québec and the federal laws of Canada applicable therein. In addition, this opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the indenture and the genuineness of signatures and to such counsel’s reliance on the Bank and other sources as to certain factual matters, all as stated in the opinion letter of such counsel dated December 20, 2023, which has been filed as Exhibit 5.3 to the Bank’s Form 6-K filed with the SEC dated December 20, 2023.

In the opinion of Davis Polk & Wardwell LLP, as special United States products counsel to the Bank, when the Notes offered by this pricing supplement have been issued by the Bank pursuant to the indenture, the trustee has made, in accordance with the indenture, the appropriate notation to the master note evidencing such Notes (the “master note”), and such Notes have been delivered against payment as contemplated herein, such Notes will be valid and binding obligations of the Bank, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith) and possible judicial or regulatory actions or applications giving effect to governmental actions or foreign laws affecting creditors’ rights, provided that such counsel expresses no opinion as to (i) the enforceability of any waiver of rights under any usury or stay law or (ii) the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law on the conclusions expressed above. This opinion is given as of the date hereof and is limited to the laws of the State of New York. Insofar as the foregoing opinion involves matters governed by the laws of the Provinces of Ontario and Québec and the federal laws of Canada, you have received, and we understand that you are relying upon, the opinion of Norton Rose Fulbright Canada LLP, Canadian counsel for the Bank, set forth above. In addition, this opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the indenture and the authentication of the master note and the validity, binding nature and enforceability of the indenture with respect to the trustee, all as stated in the opinion of Davis Polk & Wardwell LLP dated May 16, 2024, which has been filed as an exhibit to the Bank’s Form 6-K filed with the SEC on May 16, 2024.

ANNEX A

The Markit iBoxx^® USD Liquid Investment Grade Index

All information contained in this pricing supplement regarding the Markit iBoxx^® USD Liquid Investment Grade Index (the “IG Index”), including, without limitation, its make-up, method of calculation and changes in its components, has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, S&P Dow Jones Indices LLC (“S&P Dow Jones”) and Markit IHS Markit Benchmark Administration Limited (“IHS Markit”). The IG Index is calculated, maintained and published by S&P Dow Jones and IHS Markit. S&P Dow Jones and IHS Market have no obligation to publish, and may discontinue the publication of, the IG Index.

The IG Index is reported by Bloomberg under the ticker symbol “IBOXIG.”

The IG Index is a market-value weighted index that is designed to reflect the performance of U.S. dollar (“USD”)-denominated investment-grade corporate debt issued by companies from developed countries that is for sale in the United States and rated by at least one of three rating agencies: Fitch Ratings, Moody’s Investors Service or S&P Global Ratings.

Bond Selection Criteria

The IG Index is rebalanced once each month at the month-end. The bonds in the IG Index must meet all the criteria described below as of the close of business three business days prior to the rebalancing date, provided that the relevant bond data can be verified as of that date (the “bond selection cut-off date”). The new index composition becomes effective on the first business day of the next month.

The following selection criteria are applied to select the constituents of the IG Index.

Bond Type

Only fixed-rate bonds whose cash flow can be determined in advance are eligible for the IG Index. The IG Index is composed solely of bonds. T-Bills and other money market instruments are not eligible. The IG Index includes only USD-denominated bonds.

In particular, bonds with the following characteristics are included:

The following instrument bond types are specifically excluded from the IG Index: preferred shares; optionally and mandatory convertible bonds; subordinated bank or insurance debt with mandatory contingent conversion features or with any conversion options before the first call date; bonds with other equity features attached (e.g., options/warrants); perpetual bonds; fixed-to-floater bonds (except senior fixed-to-float bonds issued by banks with a call option up to 25 months prior to maturity); floating rate notes; pay-in kind bonds (during the pay-in-kind period); zero coupon bonds; zero step-ups (GAINS); bonds with differences between accrual and coupon payment periods and monthly-paying bonds; private placements; retail bonds; and extended bonds

For retail bonds and private placements, publicly available information is not always conclusive and the classification of a bond as a retail bond or a private placement will be made at S&P Dow Jones’s discretion based on the information available

at the time of determination. Any bonds classified as retail or private placement is added to the list of excluded private placements and retail bonds.

In instances where a new bond type is not specifically excluded or included according to the published index rules, S&P Dow Jones will analyze the features of such securities in line with the principles above. S&P Dow Jones may consult the specific index committees. Any decision as to the eligibility or ineligibility of a new bond type will be published and the index rules will be updated accordingly.

Credit Rating

All bonds in the IG Index must have an iBoxx^® Rating of investment grade. Ratings from Fitch Ratings, Moody’s Investment Service and S&P Global Ratings are considered for the calculation of the iBoxx^® Rating. Investment grade is defined as BBB- or higher from Fitch Ratings and S&P Global Ratings and Baa3 or higher from Moody’s Investor Service. Bonds with a rating of RD (Restricted Default) from Fitch Ratings or SD (Selective Default) from S&P Global Ratings are excluded from the IG Index. If a bond is rated by more than one of the above agencies, then the iBoxx^® Rating is the average of the provided ratings. The rating is consolidated to the nearest rating grade. Rating notches are not used.

Expected Remaining Life

All bonds must have at the rebalancing day an expected remaining life of at least three years. All new insertions must have an expected remaining life of at least three years and six months. The expected remaining life is calculated from the rebalancing date to the assumed workout date of the bond, by using the day count convention of the bond. The workout date for a bond is determined based on the bond features. For plain vanilla bonds, the expected workout date is the final maturity date. For dated and undated callable financial hybrid capital bonds, the workout date is assumed to be the first call date. For soft bullets, the expected workout date is determined using the first call date.

Amount Outstanding

Issue amount outstanding. The outstanding face value of a bond must be greater than or equal to USD 750 million as of the bond selection cut-off date. Partial buybacks or increases affect the outstanding face value of a prospective bond. S&P Dow Jones considers changes to the outstanding face value of a candidate bond as a result of partial or full buybacks or increases, provided that S&P Dow Jones is aware of such changes as of the bond selection cut-off date. In the case of Reg S securities that are registered as global securities, the remaining amount of the Reg S version and the registered version are recombined if the bond is not exchanged in full and if the remaining amount of the Reg S version reduces the amount outstanding below the eligibility threshold.

Issuer amount outstanding. The outstanding face value of all bonds denominated in USD from the issuer in the broader iBoxx^® USD Investment Grade universe (excluding fixed-to-float and perpetual bonds, except that senior fixed-to-float bank bonds present in the broader iBoxx^® USD Investment Grade universe are included) must be greater than or equal to USD 2 billion as of the bond selection cut-off date.

Lock-out Period and Minimum Run

Lock-out period. A bond that drops out of the IG Index at the rebalancing day is excluded from reentering the index for a three-month period. This lock-out rule takes precedence over other selection rules. A locked-out bond will not be selected, even if it qualifies for the IG Index.

Minimum run. Any bond that enters the IG Index must remain in the IG Index for a minimum of six months, provided it is not downgraded to sub-investment grade, defaulted or fully redeemed in that period.

Bond Classification

All bonds are classified based on a number of factors, including those described below.

The issuer classification is reviewed regularly based on updated information received by S&P Dow Jones, and status changes are included in the IG Index at the next rebalancing if necessary.

Denomination. Bonds must be denominated in USD with clearance and settlement available through Depository Trust and Clearing Corporation (DTCC). The securities need to be either publicly registered in the United States with the Securities and Exchange Commission or Rule 144A offerings with registration rights. Eurobonds are excluded.

Issuer. The bond must be corporate credit, i.e., debt instruments backed by corporate issuers that are not secured by specific assets. Debt issued by governments, sovereigns, quasi-sovereigns, and government-backed or guaranteed entities is excluded.

Issuer Country. Bonds from countries classified as developed markets based on the Markit Global Economic Development Classification are eligible for the IG Index. The issuer or, in the case of a finance subsidiary, the issuer’s guarantor, must be domiciled, incorporated and the country of risk must be in the countries listed as developed markets in Markit iBoxx^® Country Classification.

A new country is added to the IG Index if it is classified as developed market based on the Markit Global Economic Development Classification. A country is no longer eligible for the IG Index if it is classified as emerging market based on the Markit Global Economic Development Classification. The Markit Global Economic Development Classification is updated once per year. The results are published at the end of July. The inclusion/exclusion of a country becomes effective at the end of October.

Corporates. Bonds issued by public or private corporations. Bonds secured by a “floating charge” over some or all assets of the issuer are considered corporate bonds. Corporate bonds are further classified into Financials and Non-Financials bonds and then into their multiple-level economic sectors, according to the issuer’s business scope. Where the sector classification of a specific entity is not very clear due to the diversified business of the entity, the decision will be made at S&P Dow Jones’s discretion.

Additional Classification. Corporate debt is further classified into senior and subordinated debt. Bank senior debt structure additionally differentiates between Bail-in and Preferred bonds. The Bail-in classification captures all senior notes which are subject to write-down or conversion into a subordinated instrument on the occurrence of a resolution event, as well as senior bank debt issued by bank holding companies.

Hybrid capital issued by banking and insurance institutions is further detailed into the respective tiers of subordination.

The market information on the tier of subordination for insurance capital is often less standardized and clear than the equivalent issues by banks. In these cases, the classification is based on the maturity, coupon payment and deferral provisions of the bond from the offering circulars of the bonds.

Index Rebalancing

Rebalancing Process. The IG Index is rebalanced monthly after close of market on the last trading day of the month. Any inclusion after the index cut-off day (t-3) will not be considered in the rebalancing process, but will become effective at the end of the following month. New bonds issued are taken into account if they are publicly known to settle until the last calendar day of the month, inclusive, and if their rating and amount outstanding has become known at least three trading days before the end of the month.

Preview lists of eligible bonds are published on a weekly basis starting on the first Friday that is three business days after the previous month-end rebalance, as well as on the 6th calendar day of the month (or next index publication day if the 6th calendar day falls on a non-business day). Preview lists of eligible bonds are additionally published on t-4, t-3 trading days before the end of the month. Final components are published two business days before the end of the month (t-2).

Two business days before the end of each month, the rating and amount information for the constituents is updated and the list is adjusted for all rating and amount changes that are known to have taken place three business days before the end of the month that could also result in exclusion of the bond. However, if bonds that are part of broader US Dollar indices

become eligible into the IG Index two business days prior to rebalancing because of rating and/or amount changes, they will be included in the IG Index.

Rebalancing Procedure. In a first step, the selection criteria set out above are applied to the broader iBoxx^® USD Investment Grade universe to determine the eligible bond universe. Bond ratings and amount outstanding are used as of the bond selection cut-off date. Maturity dates remain fixed for the life of the bond. Only bonds with a first settlement date on or before the rebalancing date are included in the selection process.

Index Weights. Once the eligible bond universe has been defined, the weight for each bond is determined and if necessary, capped (applying an issuer cap of 3%). The weights and capping factors are determined on the last business day of each month using the end-of-month market values.

Index Calculation

The IG Index is calculated as an end-of-day index and distributed once daily after close of U.S. markets. On each calculation day, the level of the IG Index is calculated by adjusting the level of the IG Index from the immediately preceding rebalancing date to reflect price changes, accrued interest, coupon payments and reinvestment income on cash flows received, in each case, since the immediately preceding rebalancing date, taking into account the weight assigned to each bond on the immediately preceding rebalancing date.

The IG Index is generally calculated based on prices provided by independent bond pricing services. S&P Global Market Intelligence's Evaluated Bond Pricing Service (EVB) is the main pricing input source used for the calculation.

The IG Index is calculated based on bid and ask bond prices available at the end of the business day. S&P Dow Jones performs various quality assurance checks prior to the calculation of the IG Index. Issues identified are assessed by S&P Dow Jones and, where appropriate, the pricing provider is notified. Pricing providers will assess price challenges in accordance with their own policies and procedures. A notification of a price challenge to the pricing provider may result in the pricing provider upholding or rejecting the challenge. In the event the pricing provider upholds a price challenge, the relevant price may be updated.

New securities are included in the IG Index at their respective ask prices when they enter the index family. In the event that no price can be established for a particular security, the IG Index continues to be calculated based on the last available price. This might be the case in periods of market stress, or disruption as well as in illiquid or fragmented markets. If the required inputs become impossible to obtain, S&P Dow Jones may consult market participants prior to the next rebalancing date. Decisions are made publicly available on a timely basis and S&P Dow Jones may refer back to previous cases. In addition, data for the application of corporate actions in the IG Index may not be fully or timely available at all times. In such cases, S&P Dow Jones will estimate the approximate value based on the available data at the time of calculation.
