**Equity Index Descriptions**

**The Dow Jones Industrial Average**<sup>®</sup>**

All information contained in this underlying supplement regarding the Dow Jones Industrial Average<sup>®</sup>, 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**"). The Dow Jones Industrial Average<sup>®</sup> is calculated, maintained and published by S&P Dow Jones. S&P Dow Jones has no obligation to continue to publish, and may discontinue the publication of, the Dow Jones Industrial Average<sup>®</sup>.

The Dow Jones Industrial Average<sup>®</sup> is a price-weighted index that seeks to measure the performance of 30 U.S. blue-chip companies. The Dow Jones Industrial Average<sup>®</sup> includes constituents from a variety of sectors, excluding the Global Industry Classification Standard ("**GICS<sup>®</sup>**") transportation industry group from the industrials sector and the utilities sector. The Dow Jones Industrial Average<sup>®</sup> is reported by Bloomberg L.P. under the ticker symbol "INDU."

**Calculation of the Dow Jones Industrial Average<sup>®</sup>**

The Dow Jones Industrial Average<sup>®</sup> is price-weighted rather than market capitalization-weighted, which means that weightings are based only on changes in the stocks' prices, rather than by both price changes and changes in the number of shares outstanding. The value of the Dow Jones Industrial Average<sup>®</sup> is the sum of the primary exchange prices of each of the 30 component stocks included in the Dow Jones Industrial Average<sup>®</sup> *divided* by a divisor. The divisor used to calculate the price-weighted average of the Dow Jones Industrial Average<sup>®</sup> is not simply the number of component stocks; rather, the divisor is adjusted to smooth out the effects of price-impacting corporate actions, including price adjustments, special dividends, stock splits and rights offerings. The index divisor will also adjust in the event of an addition to or deletion from the Dow Jones Industrial Average<sup>®</sup>.

**Construction and Maintenance of the Dow Jones Industrial Average<sup>®</sup>**

The index universe consists of securities in the S&P 500<sup>®</sup> Index, excluding stocks classified under GICS**<sup>®</sup>** code 2030 (Transportation) and 55 (Utilities). While stock selection is not governed by quantitative rules, a stock typically is added only if the company has an excellent reputation, demonstrates sustained growth and is of interest to a large number of investors. Since the Dow Jones Industrial Average<sup>®</sup> is price-weighted, the Averages Committee (as defined below) evaluates stock price when considering a company for inclusion. The Averages Committee monitors whether the highest-priced stock in the Dow Jones Industrial Average<sup>®</sup> has a price more than 10 times that of the lowest. Maintaining adequate sector representation within the Dow Jones Industrial Average<sup>®</sup> is also a consideration in the selection process for the Dow Jones Industrial Average<sup>®</sup>. Companies should be incorporated and headquartered in the United States, and a plurality of revenues should be derived from the United States.

Changes to the Dow Jones Industrial Average<sup>®</sup> are made on an as-needed basis. There is no annual or semi-annual reconstruction. Rather, changes in response to corporate actions and market developments can be made at any time. Constituent changes are typically announced one to five days before they are scheduled to be implemented.

*Multiple Share Classes.* Each company in the Dow Jones Industrial Average<sup>®</sup> is represented once by the primary listing, which is generally the most liquid share line.

*Other Adjustments.* In cases where there is no achievable market price for a stock being deleted, it can be removed at a zero or minimal price at the discretion of the Averages Committee, in recognition of the constraints faced by investors in trading bankrupt or suspended stocks.

The table below summarizes the treatment of certain corporate actions.

---

| | |
|:---|:---|
| **Corporate Action**  | **Treatment**  |
| **Company <br> addition/deletion** | <u>Addition Only</u> <br> A stock is added to the Dow Jones Industrial Average<sup>®</sup> at a weight determined by the price of the added stock relative to all other index constituents. There is a divisor adjustment.<br><u>Deletion Only</u> <br> The weights of all stocks in the Dow Jones Industrial Average<sup>®</sup> will proportionally change but relative weights will stay the same. The index divisor will change.<br>|
| **Split/reverse split** | Stock price is adjusted by the split ratio. Shares outstanding are not adjusted by the split ratio. There is a divisor adjustment. |
| **Spin-off** | Any potential impacts on index constituents from a spin-off are evaluated by the Averages Committee on a case-by-case basis. The price of the parent company is adjusted to the price of the parent company *minus* (the price of the spun-off company/share exchange ratio). The index divisor adjusts simultaneously. |
| **Ordinary dividend** | When a company pays an ordinary cash dividend, the Dow Jones Industrial Average<sup>®</sup> does not make any adjustments to the price or shares of the stock. As a result, there are no divisor adjustments to the Dow Jones Industrial Average<sup>®</sup>. |
| **Special dividend** | The stock price is adjusted by the amount of the dividend. There is a divisor adjustment. |
| **Rights offering** | All rights offerings that are in the money on the ex-date are applied under the assumption the rights are fully subscribed. The stock price is adjusted by the value of the rights. There is a divisor adjustment. |

---

**Governance of the** **Dow Jones Industrial Average<sup>®</sup>**

The Dow Jones Industrial Average<sup>®</sup> is maintained by a committee, which is currently composed of three representatives of S&P Dow Jones and two representatives of The Wall Street Journal (the "**Averages Committee**"). The Averages Committee meets regularly. At each meeting, the Averages Committee reviews pending corporate actions that may affect index constituents, statistics comparing the composition of the Dow Jones Industrial Average<sup>®</sup> to the market, companies that are being considered as candidates for addition to the Dow Jones Industrial Average<sup>®</sup> and any significant market events. In addition, the Averages Committee may revise index policy covering rules for selecting companies, treatment of dividends, share counts or other matters.

**The EURO STOXX<sup>®</sup> Select Dividend 30 Index**

All information contained in this underlying supplement regarding the EURO STOXX<sup>®</sup> Select Dividend 30 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, STOXX Limited. The EURO STOXX<sup>®</sup> Select Dividend 30 Index was created and is calculated, maintained and published by STOXX Limited, a wholly owned subsidiary of Deutsche Börse AG. STOXX Limited has no obligation to continue to publish, and may discontinue publication of, the EURO STOXX<sup>®</sup> Select Dividend 30 Index. The EURO STOXX<sup>®</sup> Select Dividend 30 Index has a base date of December 30, 1998 and a base value of 1,000. The euro price return version of the EURO STOXX<sup>®</sup> Select Dividend 30 Index is reported by Bloomberg L.P. under the ticker symbol "SD3E."

The EURO STOXX<sup>®</sup> Select Dividend 30 Index is a net dividend yield-weighted index composed of 30 of the highest dividend-paying stocks relative to their home markets selected from the components of the EURO STOXX<sup>®</sup> Index, which provides a broad representation of the developed markets in the Eurozone. See "Equity Index Descriptions—The STOXX Benchmark Indices" in this underlying supplement for additional information about the EURO STOXX<sup>®</sup> Index. The component stocks of the EURO STOXX<sup>®</sup> Select Dividend 30 Index are traded on the major exchanges of 11 Eurozone countries: Austria, Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Portugal and Spain. At any given time, some eligible countries may not be represented in the EURO STOXX<sup>®</sup> Select Dividend 30 Index. Although the EURO STOXX<sup>®</sup> Select Dividend 30 Index measures the performance of high dividend-yielding companies, it is a price return index and, therefore, the return on the EURO STOXX<sup>®</sup> Select Dividend 30 Index will not include any dividends paid on the securities that make up the EURO STOXX<sup>®</sup> Select Dividend 30 Index.

**EURO STOXX<sup>®</sup> Select Dividend 30 Index Composition and Maintenance**

Components of the EURO STOXX<sup>®</sup> Index and their secondary share lines are eligible for inclusion in the selection list for the EURO STOXX<sup>®</sup> Select Dividend 30 Index. Companies are screened for the following criteria: indicated annualized dividend (applies for components and non-components), non-negative dividend growth rate over the past five years (applies quarterly for non-components only based on gross dividend payments), dividend payments in four out of five calendar years (applies quarterly for non-components only based on gross dividend payments), non-negative payout ratio (applies for components and non-components at annual review and applies quarterly for non-components), payout ratio of less than or equal to 60% (applies quarterly for non-components only) and a minimum average daily traded value over the preceding three-months (applies quarterly for non-components) of approximately 10.00 million euros. For companies that have more than one share line, the line with the higher dividend yield is chosen.

All current companies ranked from 1 to 60 in the selection list will remain in EURO STOXX<sup>®</sup> Select Dividend 30 Index. If fewer than 30 companies are included, the highest ranked non-components are added until 30 companies are included.

The composition of the EURO STOXX<sup>®</sup> Select Dividend 30 Index is reviewed annually in March. It is also reviewed on an ongoing basis. The selection list of the EURO STOXX<sup>®</sup> Select Dividend 30 Index is reviewed and updated quarterly. Certain corporate actions (including initial public offerings, mergers and takeovers, spin-offs, delistings, bankruptcy, and price and share adjustments) that affect the EURO STOXX<sup>®</sup> Index composition are immediately reviewed. Any changes are announced, implemented and effective in line with the type of corporate action and the magnitude of the effect.

To maintain the number of components constant, a deleted company is replaced by the highest-ranked non-component on the selection list. The selection list is updated on a quarterly basis according to the review component selection process. The restrictions on the maximum count per country are applied. If a company is deleted from the EURO STOXX<sup>®</sup> Index between the annual review dates, but is still a component of the STOXX<sup>®</sup> Global TMI, the stock will remain in the EURO STOXX<sup>®</sup> Select Dividend 30 Index until the next annual review, provided that it still meets the requirements for the EURO STOXX<sup>®</sup> Select Dividend 30 Index.

If STOXX Limited becomes aware of dividend data changes for the components of the EURO STOXX<sup>®</sup> Select Dividend 30 Index, the following index adjustments may occur. The timing of the index adjustment depends on the

changes in the dividend data. If the company cancels one of its dividends, the company will be deleted from the EURO STOXX<sup>®</sup> Select Dividend 30 Index, the replacement will be announced immediately, implemented two trading days later and become effective the next trading day. The case of dividend cancellation does not apply to dividends whose payment is postponed within the same fiscal year. Dividends whose payment is postponed indefinitely or to a subsequent fiscal year are considered cancelled. In case a company pays its dividends for a fiscal year in tranches, after the first tranche has been paid, the cancellation of one or more remaining tranches or the postponement of their payment to a subsequent fiscal year is treated as a lowering of dividend.

If the company lowers its dividend, the company will remain in the EURO STOXX<sup>®</sup> Select Dividend 30 Index until the next selection list is available. If the company is ranked 60 or above on this selection list, it is retained. If it is ranked 61 or below on the selection list, it is removed and replaced by the highest-ranked non- component on that selection list. The changes will be announced on the fifth trading day of the month together with the selection list and become effective on the first trading day after the third Friday of the month. The weight factors for the new components will be published on the quarterly underlying data announcement based on previous day closing prices.

**EURO STOXX<sup>®</sup> Select Dividend 30 Index Calculation**

The EURO STOXX<sup>®</sup> Select Dividend 30 Index is calculated based on the prices of the component stocks and weighting factors. The formula for calculating the EURO STOXX<sup>®</sup> Select Dividend 30 Index value can be expressed as follows:

---

| | |
|:---|:---|
| Index = | total "units" of the EURO STOXX<sup>®</sup> Select Dividend 30 Index |
| Index = | Divisor |

---

The **"total "units" of the EURO STOXX<sup>®</sup> Select Dividend 30 Index"** is equal to the sum of the products, for each component stock, of the price, weighting factor, weighting cap factor as of the time that the STOXX EURO STOXX<sup>®</sup> Select Dividend 30 Index is being calculated.

The weighting factor for each component stock is equal to the ratio of (a) the net dividend of the issuer of that component stock divided by the closing price of that component stock (the "net dividend yield") to (b) the sum of the net dividend yields of the issuers of all component stocks. The weighting factors are published on the second Friday in March, one week prior to quarterly review implementation using Thursday's closing prices.

The weighting cap factor limits the weight of each component stock within the EURO STOXX<sup>®</sup> Select Dividend 30 Index to a maximum of 15% at the time of each review. In addition, the EURO STOXX<sup>®</sup> Select Dividend 30 Index applies a weighting cap factor for each component stock of (1,000,000,000 × initial weight of that component / closing price of that component stock in euros), rounded to the nearest integer.

The EURO STOXX<sup>®</sup> Select Dividend 30 Index is also subject to a divisor, which is adjusted to maintain the continuity of the EURO STOXX<sup>®</sup> Select Dividend 30 Index values across changes due to corporate actions. Changes in weights due to corporate actions are distributed proportionally across all stock components of the EURO STOXX<sup>®</sup> Select Dividend 30 Index. The following is a summary of the adjustments to any component stock made for corporate actions and the effect of such adjustment on the divisor, where the shareholders of the component stock will receive "B" number of shares for every "A" share held (where applicable). All corporate actions and dividends are implemented at the effective date (ex-date).

**(1) Special cash dividend:**<br>Cash distributions that are outside the scope of the regular dividend policy or that the company defines as an extraordinary distribution<br>New adjusted price = closing price on the day before the effective date – dividend announced by the company × (1 – withholding tax if applicable)<br>Divisor: decreases<br>

---

| | |
|:---|:---|
| **(2) Split and reverse split:**<br>New adjusted price = closing price × A / B<br>New adjusted weighting factor = weighting factor on the day before the effective date × B / A<br>Divisor: unchanged | **(2) Split and reverse split:**<br>New adjusted price = closing price × A / B<br>New adjusted weighting factor = weighting factor on the day before the effective date × B / A<br>Divisor: unchanged |
| **(3) Rights offering (standard rights issue):**<br>If the subscription price is not available or if the subscription price is equal to or greater than the closing price on the day before the effective date, then no adjustment is made.<br>If the subscription price is available as a price range and not as a fixed price, the price and share adjustment is performed only if both lower and upper range are in the money.

**The FTSE<sup>®</sup> 100 Index**

All information in this underlying supplement regarding the FTSE<sup>®</sup> 100 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, FTSE Russell ("**FTSE**"). The FTSE<sup>®</sup> 100 Index is calculated, maintained and published by FTSE. FTSE has no obligation to continue to publish, and may discontinue the publication of, the FTSE<sup>®</sup> 100 Index.

The FTSE<sup>®</sup> 100 Index is an index calculated, published and disseminated by FTSE, a wholly owned subsidiary of London Stock Exchange Group plc (the "**LSEG**"). The FTSE<sup>®</sup> 100 Index measures the composite price performance of the 100 largest U.K. companies (determined on the basis of market capitalization) traded on the London Stock Exchange (the "**LSE**"). Publication of the FTSE<sup>®</sup> 100 Index began in January 1984. The FTSE<sup>®</sup> 100 Index is reported by Bloomberg L.P. under the ticker symbol "UKX.

**Composition of the FTSE<sup>®</sup> 100 Index**

The 100 stocks included in the FTSE<sup>®</sup> 100 Index (the "**FTSE Underlying Stocks**") are selected from a reference group of stocks of U.K. companies trading on the LSE that are selected by excluding certain stocks that have low liquidity, free float or price reliability or a low percentage of voting rights in the hands of unrestricted shareholders. To determine the index membership, all companies with eligible securities are ranked by their full market capitalization (*i.e.,* before the application of any investability weightings). Only the listed equity shares of a company are included in the calculation of its market capitalization. Where a company has two or more classes of listed equity shares, the secondary lines are included in the calculation of the market capitalization of the company, based on the market price of that secondary line. The FTSE Underlying Stocks are selected from this reference group by selecting 100 stocks with the largest market value.

A company will be considered a U.K. company if it is U.K. incorporated, it has its sole listing in the U.K. and its stock has a minimum free float of 10%. If a company is not incorporated in the U.K., the company will be eligible to be considered a U.K. company if it publicly acknowledges adherence to the principles of the U.K. Corporate Governance Code, pre-emption rights and the U.K. Takeover Code, as far as practicable, and its stock has a minimum free float of 25%. A company will be allocated to a single country. Where the company has a dual class structure, the minimum free float will be calculated at individual security level.

Companies are required to have greater than 5% of the company's voting rights (aggregated across all of its equity securities, including, where identifiable, those that are not listed or trading) in the hands of unrestricted shareholders in order to be eligible for index inclusion. The voting rights screen is applied to any potential new constituents on a quarterly basis, and existing constituents will be tested on an annual basis in conjunction with the June review.

The FTSE<sup>®</sup> 100 Index is overseen and reviewed quarterly by the FTSE Russell Europe, Middle East & Africa Regional Equity Advisory Committee (the "**Index Steering Committee**") in order to maintain continuity in the level. The Index Steering Committee undertakes the reviews of the FTSE<sup>®</sup> 100 Index and ensures that constituent changes and index calculations are made in accordance with the ground rules of the FTSE<sup>®</sup> 100 Index. The FTSE<sup>®</sup> 100 Index is reviewed on a quarterly basis in March, June, September and December. Each review is based on data at the end of day on the Tuesday before the first Friday of the review month. Any constituent changes are implemented after the close of business on the third Friday of the review month (*i.e.,* effective Monday), following the expiry of the ICE Futures Europe futures and options contracts.

The FTSE Underlying Stocks may be replaced, if necessary, in accordance with deletion/addition rules that provide generally for the removal and replacement of a stock from the FTSE<sup>®</sup> 100 Index if such stock is delisted, ceases to have a firm quotation or its issuer is subject to a takeover offer that has been declared unconditional with bidders' shareholding reaching at least 75% and irrevocably accepted for payment (the minimum required to approve the cancellation of a listing on the London Stock Exchange), or it has ceased, in the opinion of the Index Steering Committee, to be a viable component of the FTSE<sup>®</sup> 100 Index. To maintain continuity, a stock will be added at the quarterly review if it has risen to 90th place or above and a stock will be deleted if at the quarterly review it has fallen to 111th place or below, in each case ranked on the basis of market capitalization. A constant number of constituents will be maintained for the FTSE<sup>®</sup> 100 Index. Where a greater number of companies qualify

to be inserted in the FTSE<sup>®</sup> 100 Index than those qualifying to be deleted, the lowest ranking constituents presently included in the FTSE<sup>®</sup> 100 Index will be deleted to ensure that an equal number of companies are inserted and deleted at the periodic review. Likewise, where a greater number of companies qualify to be deleted than those qualifying to be inserted, the securities of the highest ranking companies which are presently not included in the FTSE<sup>®</sup> 100 Index will be inserted to match the number of companies being deleted at the periodic review.

Companies that are large enough to be constituents of the FTSE<sup>®</sup> 100 Index but do not pass the liquidity test are excluded. They will remain ineligible until the next annual review in June when they will be re-tested against all eligibility screens.

**Calculation of the FTSE<sup>®</sup> 100 Index**

The FTSE<sup>®</sup> 100 Index is an arithmetic weighted index where the weights are the market capitalization of each company. The FTSE<sup>®</sup> 100 Index is calculated by summing the free float-adjusted market values (or capitalizations) of all companies within the FTSE<sup>®</sup> 100 Index divided by the divisor. On the base date, the divisor is calculated as the sum of the market capitalizations of the index constituents divided by the initial index value of 1,000. The divisor is subsequently adjusted for any capital changes in the index constituents. In order to prevent discontinuities in the FTSE<sup>®</sup> 100 Index in the event of a corporate action or change in constituents, it is necessary to make an adjustment to the prices used to calculate the FTSE<sup>®</sup> 100 Index to ensure that the change in the FTSE<sup>®</sup> 100 Index between two consecutive dates reflects only market movements rather than including change due to the impact of corporate actions or constituent changes. This ensures that the index values remain comparable over time and that changes in the index level properly reflect the change in value of a portfolio of index constituents with weights the same as in the FTSE<sup>®</sup> 100 Index.

**Corporate Events Affecting the FTSE<sup>®</sup> 100 Index**

FTSE Russell applies corporate actions to the FTSE<sup>®</sup> 100 Index on a daily basis. FTSE Russell has stated as general principles that the treatment of corporate events (a) should reflect how such events are likely to be dealt with in investment portfolios to maintain the portfolio structure in line with the target set out in the index objective and index methodology and (b) should normally be designed to minimize the trading activity required by investors to match the index performance. No assurance can be provided that corporate actions and events will be treated by FTSE Russell in a manner consistent with its statement of general principles.

In addition, FTSE Russell has established guidance for the treatment of corporation actions and events, including, but not limited to, dividends, capital repayments, companies converting to a REIT structure, share buybacks, rights issues, mergers, acquisitions, tender offers, split-offs, spin-offs, bankruptcies, insolvencies, liquidations and trading suspensions. However, because of the complexities involved in some cases, those guidelines are not definitive rules that will determine FTSE Russell's actions in all circumstances. FTSE Russell reserves the right to determine the most appropriate method of implementation for any corporate event which is not covered by those guidelines or which is of a complex nature.

**License Agreement**

The use of and reference to the FTSE<sup>®</sup> 100 Index in connection with the securities has been consented to by FTSE Russell. All rights to the FTSE<sup>®</sup> 100 Index are owned by FTSE Russell, the publisher of the FTSE<sup>®</sup> 100 Index. Citigroup Inc. and its affiliates disclaim all responsibility for the calculation or other maintenance of or any adjustments to the FTSE<sup>®</sup> 100 Index. In addition, FTSE Russell has no relationship to Citigroup Inc., any of its affiliates or the securities. FTSE Russell does not sponsor, endorse, authorize, sell or promote the securities, and does not have any obligation or liability in connection with the administration, marketing or trading of the securities.

The MSCI Turkey Investable Market Index covers approximately 99% of the free float-adjusted market capitalization in Turkey. The Turkish lira price return version of the MSCI Turkey Investable Market Index is reported by Bloomberg L.P. under the ticker symbol "MXTR."

**The MSCI World Index<sup>℠</sup>**

The MSCI World Index<sup>℠</sup> is a free float-adjusted market capitalization index that is designed to measure the equity market performance of the large- and mid-cap segments of certain developed markets. The MSCI World Index<sup>℠</sup> currently consists of the following 23 developed market country indices: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom and the United States. The MSCI World Index<sup>℠</sup> covers approximately 85% of the free float-adjusted market capitalization in each country. The U.S. dollar price return version of the MSCI World Index<sup>℠</sup> is reported by Bloomberg L.P. under the ticker symbol "MXWO."

**Constructing the MSCI Global Investable Market Indices**

The MSCI Global Investable Market Indices are constructed and maintained at an individual market level. MSCI undertakes an index construction process that, with respect to the MSCI Global Investable Market Indices, involves: (i) defining the equity universe for each market; (ii) determining the market investable equity universe for each market; (iii) determining market capitalization size segments for each market and (iv) applying index continuity rules for the Standard Index (as defined below); and classifying securities under the GICS**<sup>®</sup>**.

*Defining the Equity Universe*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. Identifying Eligible Equity Securities: All listed equity securities, including REITs and certain income trusts listed in Canada,
are eligible for inclusion in the equity universe. Limited partnerships, limited liability companies and business trusts, which are listed
in the United States and are not structured to be taxed as limited partnerships, are likewise eligible for inclusion in the equity universe.
Conversely, mutual funds, exchange-traded funds, equity derivatives and most investment trusts are not eligible for inclusion in the equity
universe. Preferred shares that exhibit characteristics of equity securities are eligible. Stapled securities are considered eligible
if each of the underlying components exhibit characteristics of equity securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. Country Classification of Eligible Securities: The equity universe initially looks at securities listed in any of the countries in
the MSCI global index series, which will be classified as a developed market ()"**DM** "), emerging market ()"**EM** ")
or frontier market. Each company and its securities (*i.e.*, share classes) are classified in one and only one country, which allows
for a distinctive sorting of each company by its respective country.

*Determining the Market Investable Equity Universes*

A market investable equity universe for a market is derived by (i) identifying eligible listings for each security in the equity universe and (ii) applying investability screens to individual companies and securities in the equity universe that are classified in that market. A market is equivalent to a single country, except in DM Europe, where all DM countries in Europe are aggregated into a single market for index construction purposes. Subsequently,

individual DM Europe country indices within the MSCI Europe Index are derived from the constituents of the MSCI Europe Index under the Global Investable Market Indices methodology. The global investable equity universe is the aggregation of all market investable equity universes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. Identifying Eligible Listings: A security may have a listing that trades in the country where it is classified (a "**local listing**") and/or a listing that trades in a different country (a "**foreign listing** "). A security may be represented
by either a local listing or a foreign listing (including a depositary receipt) in the global investable equity universe as determined
by MSCI.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. Applying Investability Screens: Some of the investability requirements are applied at the individual security level and some at the
overall company level, represented by the aggregation of individual securities of the company. As such, the inclusion or exclusion of
one security does not imply the automatic inclusion or exclusion of other securities of the same company.

The investability screens used to determine the investable equity universe in each market are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Equity Universe Minimum Size Requirement: This investability screen is applied
at the company level. In order to be included in a market investable equity universe, a company must have the required minimum full market
capitalization. A company will meet this requirement if its cumulative free float-adjusted market capitalization is within the top 99%
of the equity universe sorted in descending order by full market capitalization.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Equity Universe Minimum Free Float-Adjusted Market Capitalization Requirement:
This investability screen is applied at the individual security level. To be eligible for inclusion in a market investable equity universe,
a security must have a free float-adjusted market capitalization equal to or higher than 50% of the equity universe minimum size requirement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· DM and EM Minimum Liquidity Requirement: This investability screen is applied
at the individual security level. To be eligible for inclusion in a market investable equity universe, a security must have adequate liquidity
as measured by the annualized traded value ratio ()"**ATVR**") and the frequency of trading. In addition to the ATVR and
frequency of trading requirements, securities in the MSCI China equity universe will not be eligible for inclusion in the market investable
equity universe if the securities are suspended on the price cutoff date of the index review or have been suspended for 50 consecutive
days or more in the past 12 months.

Only one listing per security may be included in the market investable equity universe. In instances when a security has two or more eligible listings that meet the above liquidity requirements, then the following priority rules are used to determine which listing will be used for potential inclusion of the security in the market investable equity universe: (i) local listing; (ii) foreign listing in the same geographical region and (iii) foreign listing in a different geographical region.

Due to liquidity concerns relating to securities trading at very high stock prices, a security with a stock price above $10,000 will fail the liquidity screening and will not be included in any market investable equity universe. This limitation applies only for securities that are not currently constituents of the MSCI Global Investable Market Indices. Current constituents of the MSCI Global Investable Market Indices will remain in their respective indices even if their stock price passes $10,000.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Global Minimum Foreign Inclusion Factor Requirement: This investability screen
is applied at the individual security level. To be eligible for inclusion in a market investable equity universe, a security's foreign
inclusion factor ()"**FIF**") must reach a certain threshold. The FIF of a security is defined as the proportion of shares
outstanding that is available for purchase in the public equity markets by international investors. This proportion accounts for the available
free float of and/or the foreign ownership limits applicable to a specific security (or company). In general, a security must have an
FIF equal to or larger than 0.15 to be eligible for inclusion in a market investable equity universe. Exceptions to this general rule
are made only in the limited cases where the exclusion of securities of a very large company would compromise the Standard Index's
ability to fully and fairly represent the characteristics of the underlying market.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Minimum Length of Trading Requirement: This investability screen is applied
at the individual security level. For an initial public offering ()"**IPO**") to be eligible for inclusion in a market investable
equity universe, the new issue must have started trading at least three months before the implementation of a semi-annual index review.
This requirement is applicable to small new issues in all markets. Large IPOs and large primary/secondary offerings of non-index constituents
are not subject to this requirement and may be included in a market investable equity universe and the Standard Index outside of a quarterly
or semi-annual index review.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Minimum Foreign Room Requirement: This investability screen is applied at
the individual security level. For a security that is subject to a foreign ownership limit to be eligible for inclusion in a market investable
equity universe, the proportion of shares still available to foreign investors relative to the maximum allowed (referred to as "**foreign room**") must be at least 15%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Financial Reporting Requirement: This investability screen is applied at the
company level. Companies classified as belonging to the United States must file a Form 10-K/10-Q to be eligible for inclusion in the United
States investable equity universe.

*Defining Market Capitalization Size Segments for Each Market*

Once a market investable equity universe is defined, it is segmented into the following size-based indices (each, a "**Size Segment Index**"), with the following free float-adjusted market capitalization market coverage target ranges:

&nbsp;&nbsp;&nbsp;&nbsp;· Investable Market Index (Large + Mid + Small): 99%+1% or -0.5%

&nbsp;&nbsp;&nbsp;&nbsp;· Standard Index (Large + Mid): 85% ± 5%

&nbsp;&nbsp;&nbsp;&nbsp;· Large Cap Index: 70% ± 5%

&nbsp;&nbsp;&nbsp;&nbsp;· Mid Cap Index: The Mid Cap Index market coverage in each market is derived
as the difference between the market coverage of the Standard Index and the Large Cap Index in that market.

&nbsp;&nbsp;&nbsp;&nbsp;· Small Cap Index: The Small Cap Index market coverage in each market is derived
as the difference between the free float-adjusted market capitalization coverage of the Investable Market Index and the Standard Index
in that market.

Creating the Size Segment Indices in each market involves the following steps: (i) defining the market coverage target range for each size segment; (ii) determining the global minimum size range for each size segment; (iii) determining the market size segment cutoffs and associated segment number of companies; (iv) assigning companies to the size segments; and (v) applying final size-segment investability requirements (which includes minimum free float market capitalization requirements, minimum foreign room requirements, and exclusions for securities that exhibit extreme price increases).

*Index Continuity Rules for the Standard Indices*

In order to achieve index continuity, as well as provide some basic level of diversification within a market index, notwithstanding the effect of other index construction rules, a minimum number of five constituents will be maintained for a DM Standard Index and a minimum number of three constituents will be maintained for an EM Standard Index.

If, after the application of the index construction methodology, a Standard Index contains fewer than five securities in a DM or three securities in an EM, then the largest securities by free float-adjusted market capitalization among the securities included in the market investable equity universe are added to the Standard Index in order to reach five constituents in that DM or three in that EM. At subsequent index reviews, if the minimum number of securities described above is not met, then after the market investable equity universe is identified, the securities are ranked by free float-adjusted market capitalization, however, in order to increase stability the free float-adjusted market capitalization of the existing index constituents (prior to review) is multiplied by 1.5, and securities are added until the desired minimum number of securities is reached.

*Classifying Securities under the Global Industry Classification Standard* 

All securities in the global investable equity universe are assigned to the industry that best describes their business activities. To this end, MSCI has designed, in conjunction with S&P Dow Jones Indices, the GICS<sup>®</sup>. The GICS<sup>®</sup> entails four levels of classification: (i) sector; (ii) industry groups; (iii) industries; and (iv) sub-industries. Under the GICS<sup>®</sup>, each company is assigned uniquely to one sub-industry according to its principal business activity. Therefore, a company can belong to only one industry grouping at each of the four levels of the GICS<sup>®</sup>. The GICS<sup>®</sup> classification of each security is used by MSCI to construct additional indices.

*Constructing and Calculating the Individual Global Investable Market Indices*

After companies are allocated to their respective size segments and securities are reviewed for complying with the final size-segment requirements, the final list of constituents for each Size Segment Index is determined. The MSCI Investable Market Indices are composed of the MSCI Standard Indices and the MSCI Small Cap Indices. The MSCI Standard Indices are further subdivided into the MSCI Large Cap and the MSCI Mid Cap Indices. Two or more market indices can be combined to form composite indices. Market indices can be grouped either on the basis of market classification definition, geographical regions, economic regions or other criteria.

**Maintenance of the MSCI Global Investable Market Indices**

The MSCI Global Investable Market Indices are maintained with the objective of reflecting the evolution of the underlying equity markets and segments on a timely basis, while seeking to achieve index continuity, continuous investability of constituents and replicability of the indices, and index stability and low index turnover.

In particular, index maintenance involves semi-annual index reviews in May and November of the Size Segment and Global Value and Growth Indices and quarterly index reviews in February and August of the Size Segment Indices. Semi-annual index reviews include updating the indices on the basis of a fully refreshed equity universe; taking buffer rules into consideration for migration of securities across size and style segments; and updating FIFs and number of shares ("**NOS**"). Quarterly index reviews include adding significant new eligible securities (such as IPOs that were not eligible for earlier inclusion) in the index; allowing for significant moves of companies within the Size Segment Indices, using wider buffers than in the semi-annual index reviews; and reflecting the impact of significant market events on FIFs and updating NOS.

In addition, ongoing event-related changes to the indices are made as the result of mergers, acquisitions, spin-offs, bankruptcies, reorganizations and other similar corporate events. They can also result from capital reorganizations in the form of rights issues, bonus issues, public placements and other similar corporate actions that take place on a continuing basis. These changes generally are reflected in the indices at the time of the event. Significantly large IPOs are included in the indices after the close of the company's tenth day of trading.

**Index Calculation** 

The MSCI Indices are calculated using the Laspeyres' concept of a weighted arithmetic average together with the concept of chain-linking. As a general principle, today's index level is obtained by applying the change in the market performance to the previous period index level.

**Treatment of Investment Sanctions Related to U.S. Executive Order 13959**

The U.S. Executive Order 13959 dated November 12, 2020 which prohibits transactions by U.S. persons in certain Chinese companies (the "**Order**"), along with clarification from the Office of Foreign Assets Control ("**OFAC**"), results in the deletion from/non-inclusion in the MSCI Global Investable Market Indices of relevant impacted securities.

On January 5, 8 and 26, 2021, MSCI deleted securities impacted by the Order from the MSCI Global Investable Market Indices. Following the amendment of the Order on June 3, 2021, OFAC has published the Non-SDN Chinese Military-Industrial Complex Companies List (the "**NS-CMIC List**") and related security tickers. MSCI deleted the securities included in OFAC's NS-CMIC List from the MSCI Global Investable Market Indices as of the close of July 26, 2021.

MSCI continues to monitor for updates to the NS-CMIC List and related security tickers impacted by the Order. Furthermore, securities which are not included in the NS-CMIC List but belong to the same issuer as a security already included in the NS-CMIC List will also be considered impacted by the Order.

Securities impacted by the Order are considered to be ineligible for inclusion in the MSCI Global Investable Market Indices. Securities that are impacted by the Order that are assigned to a size segment will have an adjustment factor of 0 applied and hence will not be included in the relevant Size Segment Indices. Existing index constituents impacted by the Order will be deleted from the MSCI Global Investable Market Indices. At the time of their deletion from the MSCI Global Investable Market Indices, the securities will be retained in their existing size segment and will continue to be included in the market investable equity universe.

**Objectives and Guiding Principles Underlying the MSCI 25/50 Indices**

Under current regulations, a fund needs to satisfy certain tests, such as those relating to asset diversification and sources of income, for qualification as an <u>RIC</u>. More specifically, one requirement of an RIC is that, at the end of each quarter of an RIC's tax year, no more than 25% of the value of the RIC's assets may be invested in a single issuer and the sum of the weights of all issuers representing more than 5% of the fund should not exceed 50% of the fund's total assets. The MSCI 25/50 Indices take into account these investment limits, aiming to offer a benchmarking alternative for RIC-compliant funds.

The following principles have guided MSCI in designing a methodology for constructing the MSCI 25/50 Indices from underlying non-constrained indices.

*Reflecting the 25% and 50% concentration constraints*. Reflecting the 25% and 50% concentration constraints is the primary consideration in terms of both index construction and index maintenance. Ensuring timely and on-going reflection of the constraints requires an MSCI 25/50 Index to be rebalanced periodically. Each MSCI 25/50 Index is rebalanced in February, May, August and November.

*Minimizing tracking error to the parent index*. Minimizing the tracking error between an MSCI 25/50 Index and the relevant parent index, while keeping the index turnover to a reasonable level, is another important objective. MSCI seeks to achieve this by rebalancing each MSCI 25/50 Index using an optimization process that aims to minimize the constituent weight differences between that MSCI 25/50 Index and the relevant parent index.

**Construction and Maintenance of the MSCI 25/50 Indices**

*Constructing and Rebalancing the MSCI 25/50 Indices*

The MSCI 25/50 Indices methodology follows a portfolio optimization framework. The "**Barra Optimizer**" is utilized to perform the optimization function, which is aimed at minimizing index turnover, tracking error and extreme deviation from the relevant parent index. The Barra Optimizer is an algorithm designed to facilitate the portfolio construction process.

*Constraint targets*. Each MSCI 25/50 Index is subject to the following constraints:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· no issuer may exceed 25% of index weight; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· all issuers with weight above 5% may not exceed 50% of the index weight.

*Minimizing tracking error from the relevant parent index.* The MSCI 25/50 Indices methodology aims at minimizing the tracking error from the relevant parent index. The tracking error of an MSCI 25/50 Index versus the relevant parent index is measured as the sum of the squared weight differences between the constituent weights of that MSCI 25/50 Index and the relevant parent index.

*Minimizing transaction cost*. A transaction cost is applied as a proxy for index turnover on rebalancing from the current MSCI 25/50 Index to the pro forma MSCI 25/50 Index.

*Minimum weight of constituents*. The minimum weight of an MSCI 25/50 Index constituent is equal to the weight of the smallest constituent in the relevant parent index.

*Maximum weight of constituents.* In order to avoid excess weight allocation to the smaller securities relative to their market capitalization weight, the maximum weight of any MSCI 25/50 Index constituent is capped at four times its weight in the relevant parent index. The constraint is relaxed in steps of one in case of infeasibilities. For certain narrow parent indices, the standard maximum weight constraint parameters might lead to an infeasible solution. In such cases, MSCI may apply relaxed constraints relative to the standard set of constraints.

*Buffer Rules*

A buffer of 10% of the value of each constraint is used in order to reduce the risk of non-compliance due to short-term market movements between two quarterly rebalancings. As a result, at the point of constructing or

rebalancing an MSCI 25/50 Index, the weight of any single issuer cannot exceed 22.5% of the index weight and all issuers with weight above 4.5% cannot exceed 45% of the index weight.

*Maintenance Rules*

*Quarterly index reviews*. Each MSCI 25/50 Index is rebalanced quarterly and the changes resulting from the rebalancing are made as of the close of the last business day of each February, May, August and November, to coincide with the quarterly index reviews of the relevant parent index.

Each MSCI 25/50 Index is in general rebalanced nine business days before the effective date. The changes resulting from the rebalancing are announced on the same day.

In case the pro forma MSCI 25/50 Index violates the 25/50 constraints between the announcement date and the effective date, the previously announced results will be discarded and a newly rebalanced MSCI 25/50 Index will be announced.

There is no index rebalancing due to non-compliance between quarterly index reviews.

At each rebalancing, a constraint factor is calculated for each constituent of an MSCI 25/50 Index. The constraint factor is defined as the weight in the relevant MSCI 25/50 Index at the time of the rebalancing divided by the weight in the relevant parent index. The constraint factor as well as the constituents of the relevant MSCI 25/50 Index remain constant between index reviews except in case of corporate events.

*Ongoing Event Related Changes.* The addition of a newly eligible security in a parent index—for example, an early inclusion of a large initial public offering, or a security migrating to that parent index from another size segment—will result in the inclusion of that security in the relevant MSCI 25/50 Index and consequently trigger the full rebalancing of that MSCI 25/50 Index.

In the event of a merger or an acquisition where an index constituent acquires another index constituent or merges with another index constituent, the remaining company is maintained in the relevant MSCI 25/50 Index with a constraint factor calculated as the weighted average of the constraint factors before the corporate event.

If a spun-off security of an index constituent is added to a parent index, it will be added to the relevant MSCI 25/50 Index with the same constraint factor as the parent security.

The deletion of a constituent from a parent index following a corporate event triggers its deletion from the relevant MSCI 25/50 Index without rebalancing of that MSCI 25/50 Index.

*Issuer Concentration Issues*

A minimum of 15 issuers in the relevant parent index is required at any point in time for the relevant MSCI 25/50 Index to be rebalanced as described above. In the event the number of issuers drops below 15 but remains above 11 following a corporate event or a regular index review, MSCI will apply the following adjustments:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Number of issuers drops to 14: the buffer mentioned above will be reduced
from 10% to 9%. Thus, the weight of any single issuer cannot exceed 22.75% of the index weight and all issuers with weight above 4.55%
cannot exceed 45.5% of the index weight.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Number of issuers drops to 13: the buffer mentioned above will be reduced
from 10% to 4%. Thus, the weight of any single issuer cannot exceed 24% of the index weight and all issuers with weight above 4.8% cannot
exceed 48% of the index weight.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Number of issuers drops to 12: the buffer mentioned above will be reduced
from 10% to 0%. Thus, the weight of any single issuer cannot exceed 25% of the index weight and all issuers with weight above 5% cannot
exceed 50% of the index weight.

An MSCI 25/50 Index will need to be discontinued if the number of issuers drops below 12 as mathematically no solution can satisfy the 25% and 50% constraints. MSCI will however temporarily maintain the relevant MSCI

25/50 Index for a minimum of two months before discontinuation by adding the necessary number of securities to that MSCI 25/50 Index. The index discontinuation will coincide with one of the subsequent regular index reviews. The securities to be added will be chosen in the following order of priority:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Securities deleted from that MSCI 25/50 Index, provided they exhibit required
liquidity and were not deleted due to financial difficulties, etc.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Eligible securities of relevant size not included in the relevant parent index
(*e.g.*, largest small cap size-segment securities).

In the event that no securities are eligible for temporary addition to an MSCI 25/50 Index, MSCI will provide an index, as close as possible to the 25/50 constraints, for a minimum of two months before discontinuation. The index discontinuation will coincide with one of the subsequent regular index reviews.

**Index Calculation and Corporate Events**

Please refer to "Equity Index Descriptions—The MSCI Indices" in this underlying supplement for information relating to the calculation of the MSCI 25/50 Indices, subject to the weight limits, buffer rules and issuer concentration issues described above, and the treatment of corporate events, subject to the maintenance rules described above. For these purposes, each MSCI 25/50 Index is deemed to be one of the MSCI Indices described in that section of the underlying supplement.

**The Nasdaq-100 Index<sup>®</sup>**

All information contained in this underlying supplement regarding the Nasdaq-100 Index<sup>®</sup>, 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, Nasdaq, Inc. ("**Nasdaq**"). The Nasdaq-100 Index<sup>®</sup> is calculated, maintained and published by Nasdaq. Nasdaq has no obligation to continue to publish, and may discontinue the publication of, the Nasdaq-100 Index<sup>®</sup>.

The Nasdaq-100 Index<sup>®</sup> is a modified market capitalization-weighted index that is designed to measure the performance of 100 of the largest non-financial companies listed on The Nasdaq Stock Market. The Nasdaq-100 Index<sup>®</sup>, which includes companies across a variety of major industry groups, was launched on January 31, 1985, with a base index value of 125.00, as adjusted. The Nasdaq-100 Index<sup>®</sup> is reported by Bloomberg L.P. under the ticker symbol "NDX."

The index share weights of the component securities of the Nasdaq-100 Index<sup>®</sup> at any time are based upon the total shares outstanding ("**TSO**") in each of those securities and are additionally subject, in certain cases, to rebalancing. Accordingly, each security's influence on the level of the Nasdaq-100 Index<sup>®</sup> is directly proportional to the value of its index share weight.

**Calculation of the Nasdaq-100 Index<sup>®</sup>**

At any moment in time, the value of the Nasdaq-100 Index<sup>®</sup> equals the aggregate value of the then-current index share weights of each of the Nasdaq-100 Index<sup>®</sup> component securities, which are based on the TSO of each such Nasdaq-100 Index<sup>®</sup> component security, multiplied by each such security's respective last sale price on The Nasdaq Stock Market (which may be the official closing price published by The Nasdaq Stock Market) and divided by a scaling factor (the "**Divisor**"), which becomes the basis for the reported Nasdaq-100 Index<sup>®</sup> value. The Divisor serves the purpose of scaling such aggregate value to a lower order of magnitude which is more desirable for index reporting purposes.

**Security Eligibility Criteria**

To qualify for index inclusion, securities must meet the following Security Eligibility Criteria, which are applied as of the reconstitution reference date.

Eligible security types include common stocks, tracking stocks and American depositary receipts, including New York Registry Shares. Companies organized as real estate investment trusts ("**REITs**"), Special Purpose Acquisition Companies ("**SPACs**") and "when-issued" securities are not eligible for index inclusion.

If an issuer has listed multiple security classes, all security classes are eligible, subject to meeting all other security eligibility criteria. For constituent selection and weighting purposes, the market capitalization of each company is the combined market capitalization of all eligible share classes. Unlisted share classes are generally ineligible and will not be considered in the calculation of a company's market capitalization.

The issuer of the security's primary U.S. listing must exclusively be listed on the Nasdaq Global Select Market or the Nasdaq Global Market.

The issuer of the security must not be classified as being in the financial industry according to the Industry Classification Benchmark (the "**ICB**"). Companies classified as being in the real estate industry by the ICB are eligible for inclusion unless organized as a REIT.

There is no minimum or maximum market capitalization eligibility criterion, although the security selection process is based in part on a ranking of companies by market capitalization. A security must have a three-month average daily traded value of at least $5,000,000.

To be eligible for initial index inclusion, a security must have been listed and available for trading on an eligible exchange for at least three full calendar months, not including the month of initial listing. For seasoning purposes, eligible exchanges include Nasdaq (Nasdaq Global Select Market, Nasdaq Global Market, or Nasdaq Capital

Market), NYSE, NYSE American and Cboe BZX. Seasoning eligibility is determined as of the constituent selection reference date and includes that month, therefore:

&nbsp;&nbsp;&nbsp;&nbsp;· To be considered for inclusion at the annual December reconstitution, a security
must have been listed and available for trading on an eligible exchange no later than the last business day of August, with seasoning
occurring over the months of September, October, and November.

&nbsp;&nbsp;&nbsp;&nbsp;· To be considered for inclusion as a replacement, a security must be seasoned
by the last day of the month preceding the replacement event. For example, if a replacement event were to occur in July, the required
seasoning period would include all of April, May, and June.

The trading history of a SPAC prior to its combination with an operating company will not count towards satisfying the seasoning requirement, regardless of whether the SPAC is determined to be the acquirer or the target in the transaction. Any security that is already a member of the Nasdaq-100 Index<sup>®</sup>, including those added as the result of a spin-off event, will be exempt from the seasoning requirement.

A security must have a free float of at least 10%.

Companies that have filed for bankruptcy or equivalent protection from creditors will not be considered for initial inclusion in the index.

A company that has entered into a definitive agreement or other arrangement that is expected to make it ineligible will not be considered for initial inclusion in the index. Such agreements or arrangements include, but are not limited to, an agreement to be purchased by another entity or to become privately owned, a plan to delist or to transfer to an ineligible exchange, a plan to reorganize as an ineligible security type or a decision to liquidate or otherwise permanently cease operations.

**Reconstitution and Rebalancing of the Nasdaq-100 Index<sup>®</sup>**

Nasdaq selects constituents once annually in December. The reconstitution reference date is the last trading day of November. Index reconstitutions are announced after market close on the second Friday in December and become effective at market open on the first trading day following the third Friday in December.

The Nasdaq-100 Index<sup>®</sup> is rebalanced on a quarterly basis in March, June, September and December. The Nasdaq-100 Index<sup>®</sup> rebalance uses the TSO and last sale price of all Nasdaq-100 Index<sup>®</sup> securities as of the prior month-end (February, May, August and November respectively). Index rebalance changes are announced after market close on the second Friday in March, June, September and December and become effective at market open on the first trading day following the third Friday in March, June, September and December.

A special rebalance may be triggered if, based on end-of-day values, any company's weight exceeds 24% or the aggregate weight of the companies whose weight exceeds 4.5% exceeds 48%. Notice of a special rebalance, including the effective date and reference date, will be published in advance.

**Constituent Selection**

A reconstitution is conducted on an annual basis, at which time all eligible companies are ranked based on market capitalization as of the reconstitution reference date. Once ranked, companies are selected for index inclusion based on the following order of criteria.

&nbsp;&nbsp;&nbsp;&nbsp;1. The top 75 ranked companies are selected for inclusion in the Nasdaq-100 Index<sup>®</sup>.

&nbsp;&nbsp;&nbsp;&nbsp;2. Any other companies that were already members of the Nasdaq-100 Index<sup>®</sup> as of the reconstitution reference date and
are ranked within the top 100 are also selected for inclusion in the Nasdaq-100 Index<sup>®</sup>.

&nbsp;&nbsp;&nbsp;&nbsp;3. If fewer than 100 companies are selected based on the first two criteria, the remaining positions will first be filled, in rank order,
by companies currently in the Nasdaq-100 Index<sup>®</sup> as of the reconstitution reference date ranked in positions 101-125, provided
that they were ranked in the top 100 at the previous

reconstitution, added as a replacement since the previous reconstitution or added as a result of a spinoff event since the previous reconstitution.

&nbsp;&nbsp;&nbsp;&nbsp;4. If fewer than 100 companies are selected based on the first three criteria, the remaining positions will be filled, in rank order,
by any companies ranked in the top 100 that were not already members of the Nasdaq-100 Index<sup>®</sup> as of the reconstitution
reference date.

The market capitalization of each company is the combined market capitalization of all eligible share classes. For inclusion purposes, the market capitalization of an ADR will normally be determined based on the depositary shares outstanding, as reported by the depositary banks. This means that a non-U.S. company represented by an ADR may be considered for inclusion in the Nasdaq-100 Index<sup>®</sup>at less than its full global market capitalization. Notwithstanding the foregoing, an ADR that serves as a company's primary global listing (*i.e.*, the underlying shares are not listed or available for trading elsewhere) will be considered for inclusion based on its full global market capitalization, in the same manner as a direct listing.

**Constituent Weighting**

The Nasdaq-100 Index<sup>®</sup> employs a modified market capitalization weighting scheme.

The quarterly weight process uses company-level weights, which are derived using the price and Total Shares Outstanding ("**TSO**") of each security as of the rebalance reference date. For any company represented by more than one eligible share class, the company weight is the combined weight of the eligible securities representing its share classes. All ADR securities selected for index inclusion will have their weights assigned according to the market capitalization of the depositary shares outstanding, as reported by the depositary banks.

***Quarterly update***

For quarterly rebalances in March, June and September, index shares for each security are adjusted by the percentage change in that company's TSO since the previous TSO update. Following those adjustments, the resulting company weights are evaluated based on two constraints:

&nbsp;&nbsp;&nbsp;&nbsp;· No company's weight may exceed 24%.

&nbsp;&nbsp;&nbsp;&nbsp;· The aggregate weight of the companies whose weights exceed 4.5% may not exceed
48%.

If neither constraint is violated, then no further adjustments are made, and the quarterly constituent weighting process is complete.

In cases where either or both of the constraints above are violated, or when the quarterly rebalance coincides with the annual reconstitution (i.e., December), quarterly weight adjustments are made according to the two-stage adjustment process described below, using the price and TSO of each security as of the rebalance reference date to derive the initial company-level weights.

*Stage 1 adjustment.* If no company's initial weight exceeds 24% of the Index, initial weights are used as Stage 1 weights without adjustment. Otherwise, initial weights are adjusted such that no company's weight may exceed 20% of the Index.

*Stage 2 adjustment.* If the aggregate weight of the companies whose Stage 1 weights exceed 4.5% does not exceed 48%, Stage 1 weights are used as the final weights. Otherwise, Stage 1 weights are adjusted such that:

&nbsp;&nbsp;&nbsp;&nbsp;· The aggregate weight of the companies whose Stage 1 weights exceeded 4.5%
is set to 40%.

&nbsp;&nbsp;&nbsp;&nbsp;· Companies with Stage 1 weights below 4.5% may also have their weights adjusted
to preserve the initial rank order of all companies.

If the two-stage process results in a violation of the weighting constraints described in this "—Quarterly update" section, then the process is repeated until the company weights meet the constraints.

***Annual weight adjustment***

The annual reconstitution employs an additional two-stage weight adjustment using security-level constraints. For any company with more than one eligible share class, the securities representing those share classes are considered separately.

Final security weights from the quarterly weight adjustment are used as the initial security weights for the annual weight adjustment process.

*Stage 1 adjustment.* If no security's initial weight exceeds 15%, initial weights are used as Stage 1 weights. Otherwise, initial weights are adjusted such that no security's weight may exceed 14% of the Index.

*Stage 2 adjustment.* If the aggregate weight of the securities with the five largest Stage 1 weights does not exceed 40%, Stage 1 weights are used as final weights. Otherwise, Stage 1 weights are adjusted such that:

&nbsp;&nbsp;&nbsp;&nbsp;· The aggregate weight of the securities with the five largest Stage 1 weights
is set to 38.5%.

&nbsp;&nbsp;&nbsp;&nbsp;· In order to preserve the initial rank order of the securities, the final
index weight of any security outside the five largest will be capped at the lesser of 4.4% or the weight of the fifth largest security.

If the two-stage process results in a violation of the weighting constraints described in this "—Annual weight adjustment" section, then the process is repeated until the security weights meet the constraints.

**Maintenance of the Nasdaq-100 Index<sup>®</sup>**

***Deletion Policy***

If, at any time, it is determined that an index security is ineligible for continued inclusion, it will be removed as soon as practicable. Advanced notice of an index security deletion, including the effective date, will be announced through the normal channels.

Criteria for security removal include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;· Delisting or transferring to an ineligible exchange.

&nbsp;&nbsp;&nbsp;&nbsp;· Reorganizing as an ineligible security type (e.g., a Real Estate Investment
Trust).

&nbsp;&nbsp;&nbsp;&nbsp;· Reclassification as a financial company, according to the ICB.

&nbsp;&nbsp;&nbsp;&nbsp;· Involvement in a merger, acquisition or other major corporate event that
would make continued inclusion impossible, impractical or inappropriate.

&nbsp;&nbsp;&nbsp;&nbsp;· Failure to maintain a weight of at least 0.10% for two consecutive month
ends.

&nbsp;&nbsp;&nbsp;&nbsp;· For a security added to the Index as the result of a spin-off event, failure
to establish a weight of at least 0.10% at the end of its second day of regular-way trading as an index member.

&nbsp;&nbsp;&nbsp;&nbsp;· Declaring bankruptcy, liquidating or otherwise permanently ceasing operations.

In circumstances where it is not possible to provide sufficient advanced notification of the removal event and/or the identity of a replacement, the security being removed may remain in the Nasdaq-100 Index<sup>®</sup> at its last sale price, or at an appropriate "deal price", until the effective date of the replacement company's entry into the Nasdaq-100 Index<sup>®</sup>. In such cases, a temporary placeholder security may be utilized, and will be denoted by adding a dollar sign to the beginning and end of the security's ticker symbol.

Securities that are added to the Nasdaq-100 Index<sup>®</sup> as the result of a spin-off event are normally maintained in the Nasdaq-100 Index<sup>®</sup>, subject to the removal criteria specified above. Those that are not immediately removed

may be removed at a later date to protect the integrity of the Nasdaq-100 Index<sup>®</sup>, for example, if a spun-off security demonstrates liquidity characteristics that diverge materially from the security eligibility criteria.

***Replacement Policy***

Other than at index reconstitution and except for spin-offs, additions to the Nasdaq-100 Index<sup>®</sup> occur only when there is a deletion that requires replacement. The company with the largest market capitalization that meets all eligibility criteria as of the prior month-end, and which is not already an index member, will replace the deleted company.

For companies represented by more than one share class, the company will only be considered deleted when all its share classes have been removed from the Nasdaq-100 Index<sup>®</sup>. If a security is removed, but other securities representing the same company remain in the Nasdaq-100 Index<sup>®</sup>, a replacement event will not be triggered.

A security that was added to the Nasdaq-100 Index<sup>®</sup> as the result of a spin-off event, and then removed before the next reconstitution, will not be replaced.

For pending deletions set to occur soon after a reconstitution and/or rebalance effective date, the removal may be accelerated to occur in conjunction with the reconstitution and/or rebalance event.

***Corporate Actions***

In the periods between scheduled index reconstitution and rebalancing events, individual index securities may be subject to a variety of corporate actions and events that require maintenance and adjustments to the Nasdaq-100 Index<sup>®</sup>.

At the quarterly rebalancing, no changes are made to the Nasdaq-100 Index<sup>®</sup> from the previous month end until the quarterly share change effective date, with the exception of corporate actions with an ex-date.

**Governance of the Nasdaq-100 Index<sup>®</sup>**

The Nasdaq-100 Index<sup>®</sup> is managed by a governance committee structure. The Index Oversight Committee is responsible for the oversight of the overall benchmark determination process and the overall governance of the U.S.-based index business, including review and approval of the control framework, certain policies and procedures, certain methodologies and methodology changes and other index management oversight. The Index Management Committee is responsible for the supervision of activities related to the development, issuance and operation of Nasdaq global indexes. The Index Management Committee meets at least quarterly and reviews each index methodology at least annually to ensure that the index achieves stated objectives and that the data and methodology remain effective.

**The Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup>**

All information contained in this underlying supplement regarding the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup>, 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, The Nasdaq Stock Market, Inc. ("**Nasdaq**"). The Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> was developed by Nasdaq and is calculated, maintained and published by The Nasdaq OMX Group, Inc. ("**Nasdaq OMX**"). Neither Nasdaq nor Nasdaq OMX has any obligation to continue to publish, and may discontinue publication of, the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup>.

The Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> is an equal-weighted, price-return index designed to measure the performance of the technology companies in the Nasdaq-100 Index<sup>®</sup>. The Nasdaq-100 Index<sup>®</sup> is a modified market capitalization-weighted index that is designed to measure the performance of 100 of the largest non-financial companies listed on The Nasdaq Stock Market. For more information about the Nasdaq-100 Index<sup>®</sup>, please see "Equity Index Descriptions—The Nasdaq-100 Index<sup>®</sup>" in this underlying supplement. The Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> is reported by Bloomberg, L.P. under the ticker symbol "NDXT."

**Constituent Selection**

The Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> contains securities of the Nasdaq-100 Index<sup>®</sup> that are classified as technology companies (i.e., companies within the technology industry) according to the Industry Classification Benchmark ("**ICB**").

If a component of the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> is removed from the Nasdaq-100 Index<sup>®</sup> for any reason, it is also removed from the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> at the same time. If a security is added to the Nasdaq-100 Index<sup>®</sup> for any reason, it may be added to the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> at the same time.

If a component of the Nasdaq-100 Index<sup>®</sup> that is classified as a technology company according to the ICB is removed and is replaced in the Nasdaq-100 Index<sup>®</sup> by a new component that is also classified as a technology company according to the ICB, the new component will be added to the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> and will assume the weight of the removed component.

If a component of the Nasdaq-100 Index<sup>®</sup> that is not classified as a technology company according to ICB is removed and is replaced in the Nasdaq-100 Index<sup>®</sup> by a new component that is classified as a technology company according to ICB, the replacement component is considered for addition to the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> at the next quarterly rebalance of the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup>.

If a component of the Nasdaq-100 Index<sup>®</sup> that is classified as a technology company according to the ICB is removed and is replaced in the Nasdaq-100 Index<sup>®</sup> by a new component that is not classified as a technology company according to the ICB, the component will be removed from the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> and the Divisor (as defined below) of the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> will be adjusted to ensure index continuity.

**Index Rebalancing**

The Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> employs an equal-weighting methodology such that each company's market value is rebalanced quarterly to an equal-dollar value corresponding to an equal percent weight of the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup>'s aggregate market value. Index shares for each component security are calculated by dividing the equal-dollar market value for that component security by its last sale price at the close of trading on the third Friday in March, June, September and December. In the case of multiple share classes of a company being included in the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup>, the equal-weighted market value will be divided equally among the securities of that company.

**Index Calculation**

At any moment in time, the value of the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> equals the aggregate value of the then-current index share weights of each of the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> component securities *multiplied by* each such security's respective last sale price on The Nasdaq Stock Market (which may be the official closing price published by The Nasdaq Stock Market) and *divided by* a scaling factor (the "**Divisor**"), which becomes the basis for the reported Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> value. The Divisor serves the purpose of scaling such aggregate value to a lower order of magnitude which is more desirable for index reporting purposes.

**Index Maintenance**

In the interim periods between scheduled index reconstitution and rebalance events, individual component securities may be the subject to a variety of corporate actions and events that require maintenance and adjustments to the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup>. Other than as a direct result of corporate actions, the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> does not normally experience share adjustments between scheduled rebalance and reconstitution events.

**Governance of the Nasdaq-100<sup>®</sup> Technology Sector Index** **<sup>℠</sup>**

The Nasdaq Index Management Committee approves all new index methodologies. This committee is comprised of full-time professional members of Nasdaq. The committee meets regularly and reviews items including, but not limited to, pending corporate actions that may affect Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> constituents, statistics comparing the composition of the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> to the market, companies that are being considered as candidates for addition to the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>℠</sup> and any significant market events.

All 225 Nikkei Underlying Stocks are stocks listed on the TSE Prime Market. Stocks listed on the TSE Prime Market are among the most actively traded stocks on the TSE. Nikkei Inc. rules require that the 75 most liquid issues (one-third of the component count of the Nikkei 225 Index) be included in the Nikkei 225 Index.

**Rules of the Periodic Review**

Nikkei Underlying Stocks are reviewed semi-annually (the "**periodic review**") in accordance with the following rules with base dates at the end of January and July, and results of the review are applied on the first trading day in April and October, respectively. Results of the review become effective on the first trading day of April and October, respectively, and the maximum number of Nikkei Underlying Stocks that can be affected is three, excluding any Nikkei Underlying Stock affected by corporate reorganization near the time of periodic review. Stocks selected by the procedures outlined below are presented as candidates to a committee composed of academics and market professionals for comment; based on comments from the committee, Nikkei Inc. determines and announces any changes to the Nikkei Underlying Stocks.

***High Liquidity Group***

The top 450 most liquid stocks are chosen from the TSE Prime Market. For purposes of this selection, liquidity is measured by (i) trading volume in the preceding 5-year period and (ii) the magnitude of price fluctuation by trading value (defined as (high price/low price)/trading value) in the preceding 5-year period. These 450 stocks constitute the "**High Liquidity Group**" for the review. Those Nikkei Underlying Stocks that are not in the High Liquidity Group are removed. Those stocks that are not currently Nikkei Underlying Stocks but that are in the top 75 of the High Liquidity Group are added.

***Sector Balance***

The High Liquidity Group is then categorized into the following six sectors: Technology, Financials, Consumer Goods, Materials, Capital Goods/Others, and Transportation and Utilities. These six sector categories are further divided into 36 industrial classifications as follows:

&nbsp;&nbsp;&nbsp;&nbsp;· Technology — Pharmaceuticals, Electrical Machinery, Automobiles &
Auto Parts, Precision Instruments and Communications;

&nbsp;&nbsp;&nbsp;&nbsp;· Financials — Banks, Other Financial Services, Securities and Insurance;

&nbsp;&nbsp;&nbsp;&nbsp;· Consumer Goods — Fishery, Food, Retail and Services;

&nbsp;&nbsp;&nbsp;&nbsp;· Materials — Mining, Textiles & Apparel, Paper & Pulp, Chemicals,
Petroleum, Rubber, Ceramics, Steel, Nonferrous Metals and Trading Companies;

&nbsp;&nbsp;&nbsp;&nbsp;· Capital Goods/Others — Construction, Machinery, Shipbuilding, Transportation
Equipment, Other Manufacturing and Real Estate; and

&nbsp;&nbsp;&nbsp;&nbsp;· Transportation/Utilities — Railway & Transport, Marine Transport,
Air Transport, Warehousing, Electric Power and Gas.

The "**appropriate number**" of constituents for each sector is defined to be half the number of stocks in that sector. After the liquidity-based adjustments, discussed above, a rebalancing is conducted if any of the sectors are over- or under-represented. The degree of representation is evaluated by comparing the actual number of constituents in the sector against the appropriate number for that sector.

For over-represented sectors, current constituents in the sector are deleted in the order of liquidity (lowest liquidity first) to correct the overage. For under-represented sectors, non-constituent stocks are added from the High Liquidity Group in the order of liquidity (highest liquidity first) to correct the shortage.

**Extraordinary Replacement Rules**

Nikkei Underlying Stocks that meet the following criteria will be deleted from the Nikkei 225 Index: designation as "**securities to be delisted**" or "**securities on alert**," delisting due to corporate restructuring such as merger, share exchange or share transfer, or transfer to a market other than the TSE Prime Market.

A constituent designated as a "security under supervision" remains a constituent at the time of designation. However, Nikkei Inc. may replace such constituent with a pre-announcement when it is highly inappropriate to keep the stock as a constituent (*e.g.* the probability of delisting is extremely high).

When a Nikkei Underlying Stock is deleted from the Nikkei 225 Index as outlined in the preceding paragraph, a new Nikkei Underlying Stock will be selected and added, in principle, from the same sector of the High Liquidity Group in order of liquidity. Notwithstanding the foregoing, the following rules may apply depending on the timing and circumstances of the deletion: (i) when such deletion is scheduled close to the time of the periodic review, additional stocks may be selected as part of the periodic review process and (ii) when multiple deletions are scheduled in a season other than the periodic review, additions may be selected using the liquidity and sector balancing rules outlined above.

**Procedures to Implement Constituent Changes**

As a general rule, for both the periodic review and the extraordinary replacement rules, additions and deletions are made effective on the same day in order to keep the number of Nikkei Underlying Stocks 225. However, under the circumstances outlined below, when an addition cannot be made on the same day as a deletion, the Nikkei 225 Index may be calculated with fewer than 225 Nikkei Underlying Stocks. In this case, the divisor is adjusted to ensure continuity.

**Calculation of the Nikkei 225 Index**

The Nikkei 225 Index is a modified, price-weighted index (*i.e.*, a Nikkei Underlying Stock's weight in the index is based on its price per share rather than the total market capitalization of the issuer) that is calculated by (i) multiplying the per share price of each Nikkei Underlying Stock by the corresponding price adjustment factor for such Nikkei Underlying Stock (a "**PAF**") (or the capped price adjustment factor in the case of a Nikkei Underlying Stock to which a capping ratio is applied as described below), (ii) calculating the sum of all these products and (iii) dividing such sum by a divisor. The divisor is subject to periodic adjustments as set forth below. The stock prices used in the calculation of the Nikkei 225 Index are those reported by a primary market for the Nikkei Underlying Stocks (currently the TSE). The level of the Nikkei 225 Index is calculated every five seconds.

The PAF of a Nikkei Underlying Stock will equal 1 if the per share price of such Nikkei Underlying Stock does not exceed 1% of the sum of the adjusted per share prices for all Nikkei Underlying Stocks. If the per share price of a Nikkei Underlying Stock exceeds 1% of the sum of the adjusted per share prices for all Nikkei Underlying Stocks, the PAF for such Nikkei Underlying Stock will be calculated in intervals of 0.1 (rounded down) and will equal the highest possible value that, when multiplied by the per share price of such Nikkei Underlying Stock, does not exceed 1% of the sum of the adjusted per share prices for all Nikkei Underlying Stocks. PAFs are evaluated semi-annually on the base dates at the end of January and July. If the average daily trading value of a stock to be added is relatively low compared with its expected weight, the stock may be added with a PAF which is one-half (rounded up

to the nearest 0.1) of the value set by the method described in the above. In this case, the PAF of that stock will in principle be raised to the planned value at the next periodic review.

Effective October 2022, if the weight of any Nikkei Underlying Stock exceeds a certain threshold ("**weight cap threshold**") on the base date of a periodic review, a capping ratio will be applied to decrease the weight of such constituent. The weight cap threshold for any Nikkei Underlying Stock is (i) 12% as of the October 2022 periodic review, (ii) 11% as of the October 2023 periodic review and (iii) 10% as of the October 2024 periodic review. For any Nikkei Underlying Stock to which a capping ratio is applied, the price of such constituent is adjusted by a capped price adjustment factor ("**CPAF**"), which is equal to (i) the capping ratio *multiplied by* (ii) the PAF.

If, on the base date of a periodic review, the weight of any Nikkei Underlying Stock exceeds the weight cap threshold and a capping ratio does not already apply to that Nikkei Underlying Stock, a capping ratio of 0.9 is applied on the effective date of the periodic review. If a capping ratio already applies to any Nikkei Underlying Stock, the capping ratio will be decreased in increments of 0.1 on the effective date of the periodic review until there is a change in the CPAF. If, on the base date of a periodic change, the weight of a Nikkei Underlying Stock to which a capping ratio is applied is below 5%, the capping ratio will be increased in increments of 0.1 on the effective date of the periodic review until there is a change in the CPAF; however, the capping ratio will be canceled if it increases to 1.0. When a Nikkei Underlying Stock to which a capping ratio is applied effects a large-scale stock split or reverse split and the PAF is adjusted by the ratio of the split or reverse split, the capping ratio may be revised as necessary to ensure that the new CPAF does not change the weight of that Nikkei Underlying Stock.

In order to maintain continuity of the Nikkei 225 Index in the event of certain changes due to non-market factors affecting the Nikkei Underlying Stocks, such as the addition or deletion of stocks, substitution of stocks, stock splits or distributions of assets to stockholders, the divisor used in calculating the Nikkei 225 Index is adjusted in a manner designed to prevent any instantaneous change or discontinuity in the level of the Nikkei 225 Index. Thereafter, the divisor remains at the new value until a further adjustment is necessary as the result of another change. As a result of such change affecting any Nikkei Underlying Stock, the divisor is adjusted in such a way that the sum of all share prices immediately after such change multiplied by the applicable PAF and divided by the new divisor (*i.e.*, the level of the Nikkei 225 Index immediately after such change) will equal the level of the Nikkei 225 Index immediately prior to the change.

In the event of a spin-off from a Nikkei Underlying Stock, when shares of the spun-off company are distributed to shareholders of that Nikkei Underlying Stock and the spun-off company will be listed, the spun-off company is temporarily incorporated into the calculation of the level of the Nikkei 225 Index between the spin-off ex-date and the listing date based upon the offering or reference price submitted by the listing sponsor. On the business day after the listing date, the spun-off company is excluded from the calculation of the level of the Nikkei 225 Index and the divisor is adjusted to maintain index continuity.

All information contained in this underlying supplement regarding the Russell 1000<sup>®</sup> Index, the Russell 2000<sup>®</sup> Index and the Russell 3000<sup>®</sup> Index (each, a "**Russell Index**" and collectively, the "**Russell Indices**"), including, without limitation, their make-up, method of calculation and changes in their components, has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, FTSE Russell, which is wholly owned by the London Stock Exchange Group. The Russell Indices are calculated, maintained and published by FTSE Russell. FTSE Russell has no obligation to continue to publish, and may discontinue the publication of, any of the Russell Indices.

**The Russell 1000<sup>®</sup> Index**

The Russell 1000<sup>®</sup> Index measures the capitalization-weighted price performance of 1,000 U.S. large-capitalization stocks listed on eligible U.S. exchanges. The companies included in the Russell 1000<sup>®</sup> Index are the 1,000 largest companies that form the Russell 3000E™ Index, which is composed of the 4,000 largest U.S. companies as determined by total market capitalization and represents approximately 99% of the U.S. equity market. The Russell 1000<sup>®</sup> Index represents approximately 93% of the United States equity market. The Russell 1000<sup>®</sup> Index is reported by Bloomberg L.P. under the ticker symbol "RIY."

**The Russell 2000<sup>®</sup> Index**

The Russell 2000<sup>®</sup> Index measures the capitalization-weighted price performance of 2,000 U.S. small-capitalization stocks listed on eligible U.S. exchanges and is designed to track the performance of the small-capitalization segment of the U.S. equity market. The companies included in the Russell 2000<sup>®</sup> Index are the middle 2,000 of the companies that form the Russell 3000E™ Index, which is composed of the 4,000 largest U.S. companies as determined by total market capitalization and represents approximately 99% of the U.S. equity market. The Russell 2000<sup>®</sup> Index is reported by Bloomberg L.P. under the ticker symbol "RTY."

**The Russell 3000<sup>®</sup> Index**

The Russell 3000<sup>®</sup> Index measures the capitalization-weighted price performance of 3,000 U.S. large-capitalization stocks listed on eligible U.S. exchanges and is designed to represent the broad U.S. equity market. The companies included in the Russell 3000<sup>®</sup> Index are the 3,000 largest U.S. companies that form the Russell 3000E™ Index, which is composed of the 4,000 largest U.S. companies as determined by total market capitalization and represents approximately 99% of the U.S. equity market. The Russell 3000<sup>®</sup> Index consists of the 3,000 companies included in the Russell 1000<sup>®</sup> Index and the Russell 2000<sup>®</sup> Index, which are subsets of the Russell 3000E™ Index, and represents approximately 97% of the U.S. equity market. The Russell 3000E™ Index is not the same as the Russell 3000<sup>®</sup> Index, which is a subset of the Russell 3000E™ Index. The Russell 3000<sup>®</sup> Index is reported by Bloomberg L.P. under the ticker symbol "RAY."

**Selection of Stocks Underlying the Russell Indices**

The Russell Indices are sub-indices of the Russell 3000E<sup>™</sup> Index. To be eligible for inclusion in the Russell 3000E™ Index and, consequently, a Russell Index, a company must meet the following criteria as of the rank day in April (except that initial public offerings ("**IPOs**") are generally considered for inclusion on a quarterly basis):

&nbsp;&nbsp;&nbsp;&nbsp;· *U.S. Equity Market.* The company must be determined to be
part of the U.S. equity market, meaning that its home country is the United States. If a company incorporates in, has a stated
headquarters location in, and also trades in the same country (ADRs and ADSs are not eligible), the company is assigned to its country
of incorporation.

If any of the three criteria do not match, FTSE Russell then defines three Home Country Indicators ("**HCIs**"): country of incorporation, country of headquarters and country of the most liquid exchange as defined by two-year average daily dollar trading volume from all exchanges within a country. After the HCIs are defined, the next step in the country assignment involves an analysis of assets by location. FTSE Russell cross-compares the primary location of the company's assets with the three HCIs. If the primary location of assets matches any of the HCIs, then the company is assigned to its primary asset location.

If there is not enough information to determine a company's primary location of assets, FTSE Russell uses the primary location of the company's revenue for the same cross-comparison and assigns the company to the appropriate country in a similar fashion. FTSE Russell uses an average of two years of assets or revenue data for analysis to reduce potential turnover.

If conclusive country details cannot be derived from assets or revenue, FTSE Russell assigns the company to the country in which its headquarters are located unless the country is a Benefit Driven Incorporation ("**BDI**") country. If the country in which its headquarters are located is a BDI country, the company is assigned to the country of its most liquid stock exchange. The BDI countries are Anguilla, Antigua and Barbuda, Aruba, Bahamas, Barbados, Belize, Bermuda, Bonaire, British Virgin Islands, Cayman Islands, Channel Islands, Cook Islands, Curacao, Faroe Islands, Gibraltar, Guernsey, Isle of Man, Jersey, Liberia, Marshall Islands, Panama, Saba, Sint Eustatius, Sint Maarten and Turks and Caicos Islands.

If a company is designated as a Chinese "N Share," it will not be considered for inclusion within the Russell Indices. An N Share is a company incorporated outside of mainland China that trades on the New York Stock Exchange, The Nasdaq Stock Market or NYSE American. An N Share will have a headquarters or principal executive office or its establishment in mainland China, with the majority of its revenue or assets derived from mainland China.

&nbsp;&nbsp;&nbsp;&nbsp;· *U.S. Eligible Exchange.* The following exchanges and markets
are deemed to be eligible U.S. exchanges: the Chicago Board Options Exchange, the New York Stock Exchange, NYSE American, The Nasdaq Stock
Market and NYSE Arca. Stocks that are not traded on an eligible U.S. exchange (Bulletin Board, Pink Sheet and over-the-counter securities,
including securities for which prices are displayed on the FINRA Alternative Display Facility) are not eligible for inclusion.

&nbsp;&nbsp;&nbsp;&nbsp;· *Minimum Closing Price.* A stock must have a close price at
or above $1.00 (on its primary exchange), subject to exceptions to reduce turnover.

&nbsp;&nbsp;&nbsp;&nbsp;· *Minimum Total Market Capitalization.* Companies with a total
market capitalization less than $30 million are not eligible for inclusion.

&nbsp;&nbsp;&nbsp;&nbsp;· *Minimum Free Float.* Companies with less than 5% of their
shares available in the marketplace are not eligible for inclusion.

&nbsp;&nbsp;&nbsp;&nbsp;· *Company Structure.* Companies structured in the following
ways are not eligible for inclusion: royalty trusts, U.S. limited liability companies, closed-end investment companies, business development
companies (and other companies that are required to report Acquired Fund Fees and Expenses, as defined by the SEC), blank-check companies,
special-purpose acquisition companies, limited partnerships, exchange-traded funds and mutual funds.

&nbsp;&nbsp;&nbsp;&nbsp;· *UBTI.* Real estate investment trusts and publicly traded
partnerships that generate or have historically generated unrelated business taxable income ()"**UBTI**") and have not taken
steps to block UBTI to equity holders are not eligible for inclusion. Information used to confirm UBTI impact includes the
following publicly available sources: 10-K, SEC Form S-3, K-1, company annual report, dividend notices or company website.

&nbsp;&nbsp;&nbsp;&nbsp;· *Security Types.* The following types of securities are not
eligible for inclusion: preferred and convertible preferred stock, redeemable shares, participating preferred stock, warrants, rights,
depositary receipts, installment receipts and trust receipts.

&nbsp;&nbsp;&nbsp;&nbsp;· *Minimum Voting Rights.* Companies are required to have greater
than 5% of the company's voting rights (aggregated across all of its equity securities, including, where identifiable, those that
are not listed or trading) in the hands of unrestricted shareholders in order to be eligible for index inclusion. Shares referenced as
"non-voting" or providing legally minimum rights only will be viewed as having no voting power as it relates to the minimum
voting rights review.

&nbsp;&nbsp;&nbsp;&nbsp;· *Multiple Share Classes.* If an eligible company trades under
multiple share classes, each share class is reviewed independently for eligibility for inclusion. Share classes in addition
to the primary share class must meet the following minimum size, liquidity and float requirements to be eligible: (i) total market cap
must be larger than $30 million; (ii) average daily dollar trading value must exceed that of the global median; and (iii) more than 5%
of shares must be available in the marketplace.

Securities of eligible companies are included in Russell Indices based on total market capitalization. Total market capitalization is determined by multiplying total outstanding shares by the market price (generally, the last price traded on the primary exchange of the share class with the highest two-year trading volume, subject to exceptions) as of the rank day in April (except that IPOs are generally considered for inclusion on a quarterly basis). Common stock, non-restricted exchangeable shares and partnership units/membership interests (but not operating partnership units of umbrella partnership real estate investment trusts) are used to calculate a company's total market capitalization. If multiple share classes of common stock exist, they are combined to determine total shares outstanding; however, in cases where the common stock share classes act independently of each other (e.g., tracking stocks), each class is considered for inclusion separately. For merger and spin-off transactions that are effective between rank day in April and the business day immediately before the index lock-down takes effect ahead of the annual reconstitution in June, the market capitalizations of the impacted securities are recalculated and membership is re-evaluated as of the effective date of the corporate action.

The 4,000 securities with the greater total market capitalization become members of the Russell 3000E™ Index. All remaining Russell Indices are a subset of the Russell 3000E™ Index. Market capitalization breakpoints for the Russell Indices are determined by the breaks between the rankings of companies (based on descending total market capitalization). Market capitalization breakpoints for the Russell 3000<sup>®</sup> Index are determined by the break between the companies ranked #1 through #3,000. Market capitalization breakpoints for the Russell 1000<sup>®</sup> Index are determined by the break between the companies ranked #1 through #1,000. Market capitalization breakpoints for the Russell 2000<sup>®</sup> Index are determined by the break between the companies ranked #1,001 through #3,000. New members are assigned on the basis of the breakpoints, and existing members are reviewed to determine if they fall within a cumulative 5% market cap range around these new market capitalization breakpoints. If an existing member's market cap falls within this cumulative 5% of the market capitalization breakpoint, it will remain in its current Russell Index rather than be moved to a different Russell Index.

After membership is determined, a security's shares are adjusted to include only those shares available to the public ("**free float**"). The purpose of this adjustment is to exclude from market calculations the capitalization that is not available for purchase and is not part of the investable opportunity set. Stocks in the Russell Indices are weighted by their available (also called float-adjusted) market capitalization.

Reconstitution occurs on the fourth Friday in June. A full calendar for reconstitution is published each spring, with such reconstitution schedule governed by FTSE Russell guidelines.

**Corporate Actions and Events Affecting the Russell Indices**

FTSE Russell applies corporate actions to the Russell Indices on a daily basis. FTSE Russell applies the following methodology guidelines, among others, when adjusting the applicable Russell Index in response to corporate actions:

&nbsp;&nbsp;&nbsp;&nbsp;· *"No Replacement" Rule.* Securities that leave
the relevant Russell Index for any reason (e.g., mergers, acquisitions or other similar corporate activity) are not replaced. Thus,
the number of securities in the relevant Russell Index over a year will fluctuate according to corporate activity.

&nbsp;&nbsp;&nbsp;&nbsp;· *Statement of Principles and Adjustments for Specific Corporate Events.* FTSE
Russell has stated as general principles that the treatment of corporate events (a) should reflect how such events are likely to be dealt
with in investment portfolios to maintain the portfolio structure in line with the target set out in the index objective and index methodology
and (b) should normally be designed to minimize the trading activity required by investors to match the index performance. No
assurance can be provided that corporate actions and events will be treated by FTSE Russell in a manner consistent with its statement
of general principles.

In addition, FTSE Russell has established guidance for the treatment of corporate actions and events, including, but not limited to, dividends, capital repayments, companies converting to a REIT structure, share buybacks, rights issues, mergers, acquisitions, tender offers, split-offs, spin-offs, bankruptcies, insolvencies, liquidations and trading suspensions. However, because of the complexities involved in some cases, those guidelines are not definitive rules that will determine FTSE Russell's actions in all circumstances. FTSE Russell reserves the right to determine the most appropriate method of implementation for any corporate event which is not covered by those guidelines or which is of a complex nature.

&nbsp;&nbsp;&nbsp;&nbsp;· *Changes to Shares Outstanding and Free Float.* Each Russell
Index will be reviewed quarterly for updates to shares outstanding and to free floats used within the calculation of each Russell Index. In
March, September and December, shares outstanding and free float will be updated to reflect cumulative share changes greater than 1%,
cumulative free float changes greater than 1% for constituents with a free float greater than 5% but less than or equal to 15% and cumulative
free float changes greater than 3% for constituents with a free float greater than 15%. In June, the shares and free float
updates will be implemented regardless of size. Shares and free float updates can be triggered in some cases by certain events,
such as some primary or secondary offerings.

**The S&P/ASX 200 Index**

All information contained in this underlying supplement regarding the S&P/ASX 200 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**"). The S&P/ASX 200 Index is calculated, maintained and published by S&P Dow Jones. S&P Dow Jones has no obligation to continue to publish, and may discontinue the publication of, the S&P/ASX 200 Index. The S&P/ASX 200 Index is reported by Bloomberg L.P. under the ticker symbol "AS51."

**Composition of the S&P/ASX 200 Index**

The S&P/ASX 200 Index is designed to be the primary gauge for the Australian equity market, and it is recognized as an investable benchmark in Australia. The S&P/ASX 200 Index measures the performance of the 200 largest and most liquid index-eligible stocks listed on the Australian Securities Exchange (the "**ASX**") by float-adjusted market capitalization.

The S&P/ASX 200 Index weights companies according to the Global Industry Classification Standard ("**GICS<sup>®</sup>**"), which creates uniform ground rules for replicable, custom-tailored, industry-focused portfolios. It also enables meaningful comparisons of sectors and industries across regions.

**Eligibility Criteria**

The index companies are drawn from the universe of ordinary and preferred equity stocks listed on ASX. The criteria for index additions include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;· *Listing*. Only securities listed on the ASX are considered
for inclusion in the S&P/ASX 200 Index;

&nbsp;&nbsp;&nbsp;&nbsp;· *Domicile.* Both domestic and foreign-domiciled entities are eligible
for inclusion in the S&P<sup>®</sup>/ASX 200 Index. Foreign-domiciled securities may be subject to specialized treatment due to
the date reporting conventions of certain foreign securities listed on the ASX. Such action is necessary in order to ensure the S&P<sup>®</sup>/ASX
200 Index remains representative of the Australian market while limiting constituent turnover and reducing index volatility

A company is considered to be domestic if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The company is incorporated in Australia and traded on the ASX; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The company is incorporated overseas but has an exclusive listing on the ASX;
or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The company is incorporated overseas and is traded on the other overseas markets,
but most of the trading activity occurs on the ASX.

Generally, a foreign-domiciled company is a company that is:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Incorporated overseas; and/or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Listed on one or more overseas markets; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Has the majority of its trading activity occurring on an overseas exchange.

When determining the domestic or foreign-domicile classification, the value and volume of shares traded on the ASX relative to any overseas market listings, are reviewed across various time periods of up to 12 months. Changes in classification will typically be made in cases where there is a clear and sustained majority of trading (60% or more) on the ASX relative to other overseas market listings, or vice versa. Any changes in classification as a result of a merger or acquisition are reviewed on case-by-case basis.

&nbsp;&nbsp;&nbsp;&nbsp;· *Eligible Securities*. To be eligible, all common and equity
preferred stocks (which are not of a fixed income nature) must be classified by GICS. Hybrid stocks, such as convertible stock, bonds,
warrants and preferred stock that provide a guaranteed fixed return, are not eligible. Listed investment companies and listed investment
trusts that invest in a portfolio of securities are not eligible. Equity and mortgage REITs are eligible for inclusion. Companies that
are currently the target of an acquisition are ineligible.

&nbsp;&nbsp;&nbsp;&nbsp;· *Market Capitalization*. The market capitalization criterion
for stock inclusion is based upon the daily average market capitalization of a security over the last three months. The ASX
stock price history (last three months, adjusted for price-adjusting corporate actions), latest available shares on issue and the investable
weight factor ()"**IWF**") are the relevant variables for the calculation. The IWF is a variable that is primarily
used to determine the available float of a security for ASX-listed securities; and

&nbsp;&nbsp;&nbsp;&nbsp;· *Liquidity*. Only securities that are regularly traded are
eligible for inclusion in the S&P/ASX 200 Index. A stock's liquidity is measured relative to its peers. Relative
Liquidity is calculated as follows:

![](image_001.jpg)

Where:

&nbsp;&nbsp;&nbsp;&nbsp;· Stock Median Liquidity is the median daily value traded on the ASX for each
stock divided by the average float/index weight-adjusted market capitalization for the previous three months; and

&nbsp;&nbsp;&nbsp;&nbsp;· Market Liquidity is calculated using the market capitalization-weighted average
of the stock median liquidities of the 500 companies in the All Ordinaries index, an index that includes nearly all ordinary shares listed
on the ASX.

Stocks must have a minimum Relative Liquidity of 50% to be included in the S&P/ASX 200 Index.

*Rebalancing.* Rebalancing of the S&P/ASX 200 Index occurs on a regular basis. Shares and IWFs updates are also applied regularly. The reference date used for the six months' worth of trading data is the second to last Friday of the month prior to the rebalancing.

*F requency.* The S&P/ASX 200 Index constituents are rebalanced quarterly, effective after the market close on the third Friday of March, June, September and December.

*Selection Buffers.* The S&P/ASX 200 Index applies selection buffers by rank for both additions and deletions. If a non-constituent ranks higher than the buffer specified below at a given review, the non-constituent is added to the S&P/ASX 200 Index in place of the existing constituent. Similarly, if a constituent falls outside the buffer rule, the constituent is removed from the S&P/ASX 200 Index.

| |
|:---|
| **Addition**  |
| 179<sup>th</sup> or higher 221<sup>st</sup> or lower |

---

This float-adjusted market capitalization rank buffer serves as the guideline used by the index committee to arrive at any potential constituent changes to the S&P/ASX 200 Index. However, the index committee has complete discretion to bypass these rules when circumstances warrant.

*Initial Public Offerings (IPOs).* An initial public offering or direct listing is added to the S&P/ASX 200 Index only when an appropriate vacancy occurs or due to a rebalance and is subject to proven liquidity for at least eight weeks. An exception may be made for extraordinary large offerings where sizeable trading volumes justify inclusion. Available price and value traded data as of the reference date is used to determine eligibility for IPOs and direct listings.

*Share Updates.* The share count for all S&P/ASX 200 Index constituents are reviewed quarterly and are rounded to the nearest thousand ('000).

Share updates for foreign-domiciled securities will take place at each quarterly rebalancing. The update to the number of shares outstanding will take place only when the three-month average of CHESS Depositary Interests ("**CDIs**") or the total securities held in the Australian branch of issuer sponsored register (where supplied) and in CHESS, on the rebalancing reference date, differs from the current number of shares used by 5% or more.

Where CDI information is not supplied to the ASX by the company or the company's share register, estimates for Australian equity capital will be drawn from CHESS data and, ultimately, registry-sourced data.

**Calculation of the S&P/ASX 200 Index**

The S&P/ASX 200 Index is calculated using a base-weighted aggregate methodology so that the level of the S&P/ASX 200 Index reflects the total market value of all the component stocks relative to a particular base period. The total market value of a company is determined by multiplying the price of its stock by the number of shares available after float (IWF) adjustment. An indexed number is used to represent the result of this calculation in order to make the value easier to work with and track over time.

*IWFs.* A stock's weight in the S&P/ASX 200 Index is determined by the float-adjusted market capitalization of the stock. The number of shares outstanding is reduced to exclude closely held shares from the calculation of the S&P/ASX 200 Index because such shares are not available to investors. The S&P/ASX 200 Index calculates an IWF, which is the percentage of total shares outstanding that are included in the calculation of the S&P/ASX 200 Index. A company must have a minimum IWF of 0.15 to be eligible for index inclusion, however an IWF at or above that level is not necessary for ongoing index membership. The IWF for foreign-domiciled securities in the S&P/ASX 200 Index is typically set to 1. IWFs are reviewed annually as part of the September quarterly rebalancing. In addition to the annual IWF review, certain events may warrant an intra-quarter or quarterly IWF update.

On any given day, the S&P/ASX 200 Index value is the quotient of the total available market capitalization of its constituents and its divisor. The key to index maintenance is the adjustment of the divisor. The purpose of the index divisor is to maintain the continuity of an index level following the implementation of corporate actions, index rebalancing events, or other non-market driven actions. Index maintenance — reflecting changes in shares outstanding, corporate actions, addition or deletion of stocks to the S&P/ASX 200 Index — should not change the level of the S&P/ASX 200 Index. Any change to the stocks in the S&P/ASX 200 Index that alters the total market value of the S&P/ASX 200 Index while holding stock prices constant will require a divisor adjustment.

**Index Governance**

The S&P/ASX 200 Index is maintained by the S&P/ASX Index Committee. S&P Dow Jones chairs the S&P/ASX Index Committee, which is comprised of five voting members representing both S&P Dow Jones and the ASX.

The S&P/ASX Index Committee meets regularly to review market developments and convenes as needed to address major corporate actions. At each meeting, the S&P/ASX Index Committee may review pending corporate actions that may affect index constituents, statistics comparing the composition of the S&P/ASX 200 Index to the market, companies that are being considered as candidates for addition to the S&P/ASX 200 Index, and any significant market events. In addition, the S&P/ASX Index Committee may revise index policy covering rules for selecting companies, treatment of dividends, share counts or other matters.

The S&P/ASX 200 Index Committee reserves the right to make exceptions when applying the methodology if the need arises. At least once within any twelve-month period, they review the methodology to ensure that the S&P/ASX 200 Index continues to achieve the stated objectives, and that the data and methodology remain effective.

**The S&P 500<sup>®</sup> Low Volatility High Dividend Index**

All information contained in this underlying supplement regarding the S&P 500<sup>®</sup> Low Volatility High Dividend Index (the "**Low Volatility High Dividend 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**"). The Low Volatility High Dividend Index is calculated, maintained and published by S&P Dow Jones. S&P Dow Jones has no obligation to continue to publish, and may discontinue the publication of, the Low Volatility High Dividend Index.

The price return of the Low Volatility High Dividend Index is reported by Bloomberg, L.P. under the ticker symbol "SP5LVHD." The Low Volatility High Dividend Index began publishing on September 17, 2012 and has a base date of January 31, 1990 and a base value of 1,000.

The Low Volatility High Dividend Index is a modified dividend yield-weighted index that is designed to measure the performance of the 50 least-volatile among the 75 highest dividend-yielding companies in the S&P 500<sup>®</sup> Index, subject to sector and individual constituent concentration limits. Although the Low Volatility High Dividend Index measures the performance of high dividend-yielding companies, it is a price return index and, therefore, the return on the Low Volatility High Dividend Index will not include any dividends paid on the securities that make up the Low Volatility High Dividend Index.

**Index Constituent Selection**

To be eligible for inclusion in the Low Volatility High Dividend Index, a stock must be a constituent of the S&P 500<sup>®</sup> Index. For additional information about the S&P 500<sup>®</sup> Index, including the methodology for inclusion in the S&P 500<sup>®</sup> Index, see "Equity Index Descriptions — The S&P U.S. Indices — The S&P 500<sup>®</sup> Index" in this underlying supplement.

S&P Dow Jones first selects the stocks to be included in the Low Volatility High Dividend Index and then weights those constituents. Generally, a stock must have been issued and trading on all trading days in the 12 months leading up to the rebalancing reference date to be included in the Low Volatility High Dividend Index. Some companies may have more than one share class or more than one listing in the S&P 500<sup>®</sup> Index. In the Low Volatility High Dividend Index, each company is represented once by the primary listing, which is generally the most liquid share class. S&P Dow Jones selects the stocks to be included in the Low Volatility High Dividend Index by ranking the stocks in the S&P 500<sup>®</sup> Index in descending order by their 12-month trailing dividend yield. Dividend yield is calculated by dividing each stock's dividends per share for the prior 12 months by the stock price as of the rebalancing reference date. Special dividends are not considered in the calculation of dividend yields. The 75 stocks with the highest dividend yield are selected, with the number of stocks from each Global Industry Classification Standard ("**GICS<sup>®</sup>**") sector capped at 10. If the number of stocks from a GICS<sup>®</sup> sector reaches 10, the remaining highest yielding stocks from other sectors are selected until the number of selected stocks reaches 75. Using available price return data for the trailing 252 trading day leading up to the rebalancing reference date, the realized volatilities of these stocks are calculated. Realized volatility is defined as the standard deviation of the stock's daily price returns over the prior 252 trading days. Those stocks are then ranked in ascending order based on their realized volatility. The 50 stocks with the lowest realized volatility form the Low Volatility High Dividend Index.

At times, a company may appear to temporarily violate one or more of the addition criteria. However, the addition criteria are for addition to the Low Volatility High Dividend Index, not for continued membership. As a result, an index constituent that appears to violate criteria for addition to the Low Volatility High Dividend Index is not deleted unless ongoing conditions warrant an index change.

At the discretion of S&P Dow Jones, a stock may be excluded from the Low Volatility High Dividend Index, or not considered for membership, at a semi-annual rebalancing if S&P Dow Jones determines the stock's dividend yield to be unsustainable.

Except for major corporate actions, such as mergers and spin-offs, additions and deletions of stocks generally only take place at the time of the reconstitution. In addition, constituents removed from the S&P 500<sup>®</sup> Index are also removed from the Low Volatility High Dividend Index simultaneously.

**Index Rebalancing**

The Low Volatility High Dividend Index is rebalanced after the close of the last business day of January and July based on market data from the rebalancing reference dates, which are the last business day of December and June, respectively. The constituents' shares are calculated using closing prices five business days prior to the rebalancing date as the reference price. The constituents' shares are calculated and assigned to each stock to arrive at the weights determined on the rebalancing reference date.

The S&P Dow Jones's U.S. Index Committee may change the date of a given rebalancing for reasons including market holidays occurring on or around the scheduled rebalancing date. Any change will be announced with proper advance notice where possible.

**Index Calculation and Governance**

The Low Volatility High Dividend Index is calculated using the same methodology as the S&P 500<sup>®</sup> Index, except that the constituents of the S&P 500<sup>®</sup> Low Volatility High Dividend Index are weighted by dividend yield. In addition, at each rebalancing, modifications are made to stock weights to increase diversification across individual stocks and sectors. The weight for each constituent of the S&P 500<sup>®</sup> Low Volatility High Dividend Index is constrained between 0.05% and 3.0%, and the weight of each GICS<sup>®</sup> sector is capped at 25%. The Low Volatility High Dividend Index is governed using the same methodology as the S&P 500<sup>®</sup> Index. For additional information about the calculation and governance of the S&P 500<sup>®</sup> Index, see "Equity Index Descriptions — The S&P U.S. Indices — The S&P 500<sup>®</sup> Index" in this underlying supplement.

**Corporate Actions**

The table below summarizes types of index maintenance adjustments and indicates whether or not a divisor adjustment is required.

|:---|:---|:---|
| **Type of<br> Corporate Action**  | **Adjustment Made to Index**  | **Divisor<br> Adjustment**  |
| Spin-off | The spun-off company is added to the Low Volatility High Dividend Index of which the parent is a constituent, at a zero price at the market close of the day before the ex-date (with no divisor adjustment). The spun-off company is then removed after at least one day of regular way trading (with a divisor adjustment). | See "Adjustment Made to Index" |
| Rights Offering | All rights offerings that are in the money on the ex-date are applied under the assumption the rights are fully subscribed. The stock price is adjusted by the value of the rights and the shares outstanding are increased by the rights ratio. The change in price and shares is offset by an adjustment weight factor to keep the company's weight unchanged. There is no change to the company's weight and no divisor adjustment. | No |
| Stock Dividend, Stock Split, Reverse Stock Split | Index shares are multiplied by and price is divided by the split factor. | No |
| Changes in Shares Outstanding | Shares outstanding changes are offset by an adjustment weight factor. There is no change to the company's weight and no divisor adjustment. | No |
| Special Dividends | Price of the stock making the special dividend payment is reduced by the per share special dividend amount after the close of trading on the day before the dividend ex-date. The net change in the company's weight will cause a divisor change. | Yes |

**Other Adjustments**

In cases where there is no achievable market price for a stock being deleted, it may be removed at a zero or minimal price at the S&P Dow Jones's U.S. Index Committee's discretion, in recognition of the constraints faced by investors in trading bankrupt or suspended stocks.

**Select Industry Index Eligibility** 

To qualify for membership in a Select Industry Index, at each quarterly rebalancing, a company must satisfy the following criteria:

&nbsp;&nbsp;&nbsp;&nbsp;· be a member of the S&P TMI;

&nbsp;&nbsp;&nbsp;&nbsp;· be included in the relevant GICS<sup>®</sup> sub-industries for the relevant
Select Industry Index (stocks included in such sub-industry, "**primary stocks** ");

&nbsp;&nbsp;&nbsp;&nbsp;· meet one of the following float-adjusted market capitalization ()"**FMC** ")
and float-adjusted liquidity ratio ()"**FALR**") requirements:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· be a current constituent, have an FMC greater than or equal to US$300 million
and have an FALR greater than or equal to 50%;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· have an FMC greater than or equal to US$500 million and an FALR greater than
or equal to 90%; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· have an FMC greater than or equal to US$400 million and an FALR greater than
or equal to 150%.

Notwithstanding the foregoing, to be eligible for inclusion in the S&P<sup>®</sup> Banks Select Industry Index, a company's FMC must be above US$2 billion and its FALR must be above 100%, and existing constituents of the S&P<sup>®</sup> Banks Select Industry Index are removed at the quarterly rebalancing date if either their FMC falls below US$1 billion or their FALR falls below 50%.

In the event that fewer than 35 stocks are selected for each Select Industry Index using the eligible primary stocks, certain indices will select stocks for inclusion from a supplementary list of highly correlated sub-industries (supplementary stocks) based on a process established by S&P Dow Jones. Additionally, minimum FMC requirements may be relaxed for all Select Industry Indices to ensure that there are at least 22 stocks in each Select Industry Index as of each rebalancing effective date.

*Liquidity.* An FALR, defined as the annual dollar value traded divided by the FMC, is used to measure liquidity. Using composite pricing and all publicly reported U.S. consolidated volume, annual dollar value traded is defined as the average closing price multiplied by the historical volume over the 365 calendar days prior to the evaluation date. This is reduced to the available trading period for stocks that do not have 365 calendar days of trading history. In these cases, the dollar value traded available as of the evaluation date is annualized. Liquidity requirements are reviewed during the quarterly rebalancings. The price, shares outstanding and IWF (as defined

below) as of the evaluation date are used to calculate the FMC. The evaluation date is the last business day of the month prior to the rebalancing effective date.

*Takeover Restrictions.* At the discretion of S&P Dow Jones, constituents with shareholder ownership restrictions defined in company bylaws may be deemed ineligible for inclusion in a Select Industry Index. Ownership restrictions preventing entities from replicating the index weight of a stock may be excluded from the eligible universe or removed from the relevant Select Industry Index. S&P Dow Jones will provide up to five days advance notification of a deletion between rebalancings due to ownership restrictions. If S&P Dow Jones's index committee (the "**Index Committee**") decides to remove or exclude a company, that company is ineligible for re-entry or inclusion, respectively, for at least one full calendar year, beginning with the subsequent rebalance.

*Multiple Share Classes.* Some companies in the S&P TMI are represented by multiple share classes. As of December 2015, each company in the Select Industry Indices is represented once by the primary listing, which is generally the most liquid share line.

**Calculation of the Select Industry Indices**

The Select Industry Indices are equal-weighted, with adjustments to individual constituent weights to ensure concentration and liquidity requirements, and calculated by means of the divisor methodology used by S&P Dow Jones for the Select Industry Indices.

The index value of each Select Industry Index is simply the market value of that Select Industry Index divided by the index divisor:

Index Value = (Index Market Value) / Divisor

Index Market Value = ![](image_002.jpg)

where N is the number of stocks in the index, P<sub>i</sub> is the price of stock i, Shares<sub>i</sub> is total shares outstanding of stock i, IWF<sub>i</sub> is the float factor of stock i (as defined below), and AWF<sub>i</sub> is the adjustment factor of stock i assigned at each index rebalancing date, t, which makes all index constituents modified market capitalization equal (and, therefore, equal weight), while maintaining the total market value of the overall index. The AWF for each index constituent, i, at rebalancing date, t, is calculated by:

AWF<sub>i,t</sub> = Z / (N × FloatAdjustedMarketValue<sub>i,t</sub>)

where Z is an index-specific constant set for the purpose of deriving the AWF and, therefore, each stock's share count used in the index calculation (often referred to as modified index shares).

*Float Adjustment.* Float adjustment means that the number of shares outstanding is reduced to exclude shares that are held by other publicly traded companies, government agencies or certain types of strategic shareholders from the calculation of the index value because such shares are not available to investors. The goal of float adjustment is to adjust each company's total shares outstanding for long-term strategic shareholders, who often have interests such as maintaining control rather than securing the shorter-term economic fortunes of the company. Generally, these long-term strategic shareholders include, but are not limited to, officers and directors, private equity, venture capital and special equity firms, asset managers and insurance companies with direct board of director representation, other publicly traded companies that hold shares, holders of restricted shares, company-sponsored employee share plans/trusts, defined contribution plans/savings, and investment plans, foundations or family trusts associated with the company, government entities at all levels (other than government retirement/pension funds), sovereign wealth funds and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. Restricted shares are generally not included in total shares outstanding except for shares held as part of a lock-up agreement. Shares that are not considered outstanding are also not included in the available float. These generally include treasury stock, stock options, equity participation units, warrants, preferred stock, convertible stock and rights.

For each component, S&P Dow Jones calculates an Investable Weight Factor ("**IWF**"), which represents the portion of the total shares outstanding that are considered part of the public float for purposes of the relevant Select Industry Index.

*Divisor.* Continuity in index values of each Select Industry Index is maintained by adjusting its divisor for all changes in its constituents' share capital after its base date. This includes additions and deletions to the relevant Select Industry Index, rights issues, share buybacks and issuances and non-zero price spin-offs. The value of each Select Industry Index's divisor over time is, in effect, a chronological summary of all changes affecting the base capital of that Select Industry Index. The divisor of each Select Industry Index is adjusted such that the index value of that Select Industry Index at an instant just prior to a change in base capital equals the index value of that Select Industry Index at an instant immediately following that change.

**Constituent Weightings**

At each quarterly rebalancing, constituents are initially equal weighted with adjustments to ensure that, for a given theoretical portfolio value ("**TPV**"), each constituent's weight in the relevant Select Industry Index does not exceed 4.5% of the FMC or the value that can be traded in three days. No stock can have a weight greater than 4.5% in the relevant Select Industry Index. TPVs are reviewed annually in September, incorporating index-linked exchange traded product assets under management ("**AUM**") using the below process:

&nbsp;&nbsp;&nbsp;&nbsp;1. Determine the maximum aggregate AUM tracking the relevant Select Industry Index over the past year, based on index-linked exchange
traded product's AUM from the previous September, December, March and June, as well as the latest available month-end data point.

&nbsp;&nbsp;&nbsp;&nbsp;2. Round the maximum value up to the nearest billion.

&nbsp;&nbsp;&nbsp;&nbsp;3. Add a 20% buffer to the result and again round up to the nearest billion for the final TPV.

If there are no index-linked exchange traded products tracking the relevant Select Industry Index, the TPV for that index is set at US$2 billion. Any updates to the TPV for an index are made at the discretion of the Index Committee and announced to clients with ample lead time.

S&P Dow Jones Indices calculates a maximum constituent weight for each index constituent equal to the lesser of (i) 4.5%, (ii) 3 *times* the ratio of the three-month median daily value traded ("**MDVT**") of the index constituent to its TPV and (iii) 4.5% *times* the ratio of the index constituent's FMC to its TPV.

The reference date for assessing the 3-month MDVT and stock price is after the close on the last business day of February, May, August and November for the rebalancings effective after the close on the third Friday of March, June, September and December, respectively.

Each constituent's initial equal weight is compared to the calculated maximum constituent weight, and the constituent's weight is set to the lesser of the maximum constituent weight or the initial equal weight. If the resulting index weights do not sum to 100%, any excess weights are iteratively redistributed to the uncapped constituents.

If all constituents are capped and the resulting index weights still do not sum to 100%, the constraints are relaxed in the following order:

&nbsp;&nbsp;&nbsp;&nbsp;1. Maximum liquidity weight multiplier in increments of 0.1,

&nbsp;&nbsp;&nbsp;&nbsp;2. Single stock cap in increments of 0.1%,

&nbsp;&nbsp;&nbsp;&nbsp;3. TPV decreasing in increments of US$100 million.

The process is repeated iteratively until a feasible solution is found. The single stock weight constraint's upper limit for the iterative process is 4.8%.

*Secondary Reweighting.* If, on the third to last business day of March, June, September or December, the aggregate weight of companies with index weights greater than 4.8% exceeds 50%, index weights reset to the

previously determined weights using the data from that quarter's reference date, with an effective date as of after the close of the last business day of the month.

If a secondary reweighting is triggered, and existing constituent(s) were dropped since the prior quarterly rebalancing, the secondary reweighting re-runs the reweighting process using the same data from the latest quarterly rebalancing.

**Maintenance of the Select Industry Indices**

*Rebalancing.* The membership of the Select Industry Indices is reviewed quarterly. Rebalancings occur after the closing on the third Friday of the quarter ending month. The reference date for additions and deletions is after the closing of the last trading date of the previous month. Closing prices as of the Wednesday prior to the second Friday of the last month of the quarter are used for setting index weights.

*Additions.* Stocks are added between rebalancings only if a deletion in the applicable Select Industry Index causes the stock count to fall below 22. In those cases, each stock deletion is accompanied by a stock addition. The new stock will be added to the applicable Select Industry Index at the weight of the deleted company.

*Deletions.* A stock is deleted from the applicable Select Industry Index if the S&P TMI drops the stock. If a stock deletion causes the number of stocks in the applicable Select Industry Index to fall below 22, each stock deletion is accompanied by a corresponding stock addition. In the case of mergers involving two index constituents, the merged entity remains in the applicable Select Industry Index provided it satisfies the eligibility criteria. If the merged entity qualifies for index inclusion, the stock deemed the target is dropped, the index shares for the acquirer will remain unchanged, and the weightings of the remaining constituents adjust proportionally.

*GICS**<sup>®</sup>** Reclassifications.* If a constituent's GICS<sup>®</sup> classification changes to an ineligible sub-industry for a given Select Industry Index, the constituent is removed from that Select Industry Index at the subsequent rebalancing.

*Spin-Offs*. The S&P Select Industry Indices follow the S&P TMI treatment of spin-offs. In general, both the parent and spin-off company remain in the relevant Select Industry Index until the subsequent rebalancing. The spin-off company is added to the relevant Select Industry Index at a zero price at the close of the day before the ex-date. No price adjustment is applied to the parent and there is no divisor change. If the spin-off company is dropped from S&P TMI the weight of the spun-off company is added back to the parent stock's weight after at least one day of trading.

*Adjustments.* The table below summarizes the treatment of certain corporate actions.

---

| | |
|:---|:---|
| **Corporate Action**  | **Treatment**  |
| **Change in shares outstanding** | Shares outstanding changes are offset by an adjustment factor (AWF). There is no change to the market capitalization of the relevant Select Industry Index and no divisor adjustment. |
| **Split/reverse split** | Shares outstanding are adjusted by the split ratio. Stock price is adjusted by the split ratio. There is no change to the market capitalization of the relevant Select Industry Index and no divisor adjustment. |
| **Change in IWF** | IWF changes are offset by an AWF. There is no change to the market capitalization of the relevant Select Industry Index and no divisor adjustment. |
| **Ordinary dividend** | When a company pays an ordinary cash dividend, the relevant Select Industry Index does not make any adjustments to the price or shares of the stock. As a result, there are no divisor adjustments to that Select Industry Index. |

---

---

| | |
|:---|:---|
| **Corporate Action**  | **Treatment**  |
| **Special dividend** | The stock price is adjusted by the amount of the dividend. The net change to the market capitalization of the relevant Select Industry Index causes a divisor adjustment. |
| **Rights offering** | All rights offerings that are in the money on the ex-date are applied under the assumption that the rights are fully subscribed. The stock price is adjusted by the value of the rights and the shares outstanding are increased by the rights ratio. The change in price and shares is offset by an AWF to keep the market capitalization (stock weight) of the relevant Select Industry Index unchanged. There is no change to the market capitalization of that Select Industry Index and no divisor adjustment. |

---

**Governance of the** **Select Industry Indices**

The Index Committee maintains the Select Industry Indices. All Index Committee members are full-time professional members of S&P Dow Jones's staff. The Index Committee meets regularly. At each meeting, the Index Committee reviews pending corporate actions that may affect the Select Industry Indices constituents, statistics comparing the composition of the Select Industry Indices to the market, companies that are being considered as candidates for addition to a Select Industry Index and any significant market events. In addition, the Index Committee may revise index policy covering rules for selecting companies, treatment of dividends, share counts or other matters.

**Select Sector Index Capping Methodology**

Each Select Sector Index is capped market capitalization-weighted. For capping purposes, the Select Sector Indices are rebalanced quarterly after the close of business on the third Friday of March, June, September and December using the following procedures:

&nbsp;&nbsp;&nbsp;&nbsp;1. The rebalancing reference date is the Wednesday prior to the second Friday of March, June, September and December.

&nbsp;&nbsp;&nbsp;&nbsp;2. With prices reflected on the rebalancing reference date, adjusted for any applicable corporate actions, and membership, shares outstanding
and investable weight factors ()"**IWFs**") as of the rebalancing effective date, each company is weighted by float-adjusted
market capitalization ()"**FMC** ").

&nbsp;&nbsp;&nbsp;&nbsp;3. If any company has an FMC weight greater than 24%, each company's weight is capped at 23%, which allows for a 2% buffer.

&nbsp;&nbsp;&nbsp;&nbsp;4. The sum of the companies with weights greater than 4.8% cannot exceed 50% of the total index weight. These caps are set to allow for
a buffer below the 5% limit.

&nbsp;&nbsp;&nbsp;&nbsp;5. If the rule in paragraph 4 is breached, the weight of each company with a weight greater than 4.8% is capped at:

![](image_003.jpg)

Where:

*N* = total number of companies with index weights over 4.8%, after checking the single company cap

*W<sub>i</sub>* = index weight of the N companies with individual company weights over 4.8%, after checking the single company cap

Set 4.5% and 45% caps to allow for a buffer below the 5% limit.

&nbsp;&nbsp;&nbsp;&nbsp;6. Proportionally redistribute the excess weight from paragraphs 3 to 5 to companies with an initial weight less than 4.8%, setting a
4.5% upper bound on the companies' index weight.

&nbsp;&nbsp;&nbsp;&nbsp;7. Assign index share amounts to each constituent to arrive at the weights calculated above. Since index shares are assigned based on
prices one week prior to rebalancing, the actual weight of each constituent at the rebalancing differs somewhat from these weights due
to market movements.

When companies represented in the Select Sector Indices are represented by multiple share classes, maximum weight capping is based on company FMC, with the weight of multiple-class companies allocated proportionally to each share class based on FMC as of the rebalancing reference date. If no capping is required, both share classes remain in the relevant Select Sector Index at their natural FMC weight.

*Secondary Reweighting Check.* If, on the second to last business day of March, June, September or December, a company's weight exceeds 24%, or the sum of the companies with weights greater than 4.8% exceeds 50%, the capping breach triggers a secondary reweighting with an effective date as of after the close of the last business day of the month. The secondary reweighting uses capped index weights as of the second to last business days of March, June, September or December, utilizing the current AWFs and membership, shares outstanding and IWFs as of the reweighting effective date.

**Calculation, Maintenance and Governance of the Select Sector Indices**

The Select Sector Indices are calculated, maintained and governed using the same methodology as the S&P 500<sup>®</sup> Index, subject to the capping methodology described above. For additional information about the calculation, maintenance and governance of the S&P 500<sup>®</sup> Index, please see "Equity Index Descriptions —The S&P U.S. Indices" in this underlying supplement.

**Composition of the S&P U.S. Indices**

Additions to the S&P U.S. Indices are evaluated based on the following eligibility criteria:

&nbsp;&nbsp;&nbsp;&nbsp;· *Domicile.* The company must be a U.S.-domiciled company. S&P Dow
Jones generally determines a company's country of domicile based on the location of its incorporation and/or registration, operational
headquarters and stock exchange listings. If all three principal factors point toward one country, then that country is generally considered
the country of domicile. When the country of incorporation and/or registration is a domicile of convenience, only the location of the
operational headquarters and stock exchange listings are considered. If any of these factors do not align, a company will generally be
assigned to its country of incorporation, unless a broader analysis considering the following factors establishes a significant link to
another country: geographic breakdown of revenue and assets, ownership information, additional stock exchange listings, the functional
and reporting currency, location of officers, directors and employees, location of annual company meetings, company history, investor
perception and other factors deemed to be relevant by S&P Dow Jones's U.S. index committee.

&nbsp;&nbsp;&nbsp;&nbsp;· *Security Filing Type.* The company issuing the security must satisfy
the U.S. Securities Exchange Act of 1934's periodic reporting obligations by filing certain required forms for domestic issuers,
such as but not limited to Form 10-K annual reports, Form 10-Q quarterly reports and Form 8-K current reports.

&nbsp;&nbsp;&nbsp;&nbsp;· *Exchange Listing.* A listing on one of the following U.S. exchanges
is required: New York Stock Exchange, NYSE Arca, NYSE American, Nasdaq Global Select Market, Nasdaq Global Market, Nasdaq Capital Market,
Cboe BZX, Cboe BYX, Cboe EDGA or Cboe EDGX exchanges. Ineligible exchanges include the over-the counter markets including the Pink Open
Market.

&nbsp;&nbsp;&nbsp;&nbsp;· *Organizational Structure and Share Type.* Eligible organizational structures
and share types are corporations, including equity and mortgage real estate investment trusts ()"**REITs** "), and common
stock (*i.e.*, shares). Ineligible organizational structures and share types include, but are not limited to, business development
companies, limited partnerships, master limited partnerships, limited liability companies, closed-end funds, exchange-traded funds, exchange-traded
notes, royalty trusts, special purpose acquisition

companies, tracking stocks, preferred and convertible preferred stock, unit trusts, equity warrants, convertible bonds, investment trusts, rights and American depositary receipts.

&nbsp;&nbsp;&nbsp;&nbsp;· *Multiple Share Classes.* Index membership eligibility for a company
with multiple share class lines is based on total market capitalization at the company level. Each publicly listed share class is evaluated
separately to determine index inclusion, with the weight of each line reflecting only that line's FMC (as defined below), not the
combined FMC of all company share class lines. Unlisted share class lines are not combined with any listed share class lines, but unlisted
share class lines are included when calculating company total market capitalization. Multiple share class lines not currently in an S&P
U.S. Index must satisfy the liquidity and FMC eligibility requirements (but not the market capitalization criteria, which is only considered
at the company level). Any excluded listed secondary lines are reviewed annually in September for potential index inclusion. Multiple
share class line deletions from an S&P U.S. Index are at the discretion of S&P Dow Jones's U.S. index committee, and, as
a result, a multiple share class line may continue to be included in an index even if the share class line subsequently fails to meet
the addition criteria.

&nbsp;&nbsp;&nbsp;&nbsp;· *Market Capitalization.* The total company market capitalization should
be within a specified range for the relevant S&P U.S. Index. These ranges are reviewed quarterly and updated as needed to ensure they
reflect current market conditions. A company meeting the total company market capitalization criteria is also required to have a security
level float-adjusted market capitalization ()"**FMC**") that is at least 50% of the relevant S&P U.S. Index's
total company level minimum market capitalization threshold.

&nbsp;&nbsp;&nbsp;&nbsp;· *IWF.* For each stock, an investable weight factor ()"**IWF** ")
is calculated, which is equal to the percentage of such stock's shares that are freely available for trading in the public market.
A stock must have a minimum IWF of 0.1 as of the rebalancing effective date to be eligible for inclusion in an S&P U.S. Index.

&nbsp;&nbsp;&nbsp;&nbsp;· *Liquidity.* A float-adjusted liquidity ratio ()"**FALR** "),
defined as the annual dollar value traded divided by the FMC, is used to measure liquidity. Using composite pricing and all publicly reported
U.S. consolidated volume, annual dollar value traded is defined as the average closing price multiplied by the historical volume over
the 365 calendar days prior to the evaluation date. This is reduced to the available trading period for initial public offerings ()"**IPOs** "),
spin-offs 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. In these cases, the dollar value traded available as of the evaluation date is annualized. The price, shares outstanding
and IWF as of the evaluation date are used to calculate the FMC. The evaluation date is the open of trading two business days prior to
the announcement date. The stock should trade a minimum of 250,000 shares in each of the six months leading up to the evaluation date.
The FALR must be greater than or equal to 0.75 at the time of addition to an S&P U.S. Index. Current index constituents have no minimum
requirement.

&nbsp;&nbsp;&nbsp;&nbsp;· *Financial Viability.* Generally Accepted Accounting Principles ()"**GAAP** ")
net income from continuing operations must be positive for the most recent quarter and the sum of the most recent four quarters. For equity
REITs, financial viability is based on GAAP net income from continuing operations and/or funds from operations, if reported.

&nbsp;&nbsp;&nbsp;&nbsp;· *Treatment of IPOs.* IPOs should be traded on an eligible exchange for
at least 12 months before being considered for addition to an S&P U.S. Index. For former special purpose acquisition companies ()"**SPACs** "),
S&P Dow Jones 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 an S&P U.S. Index. Spin-offs or in-specie distributions from
existing constituents do not need to be seasoned for 12 months prior to their inclusion in an S&P U.S. Index. Companies that migrate
from an ineligible exchange, emerge from bankruptcy, are newly designated to be domiciled in the U.S. for index purposes by S&P Dow
Jones or convert from an ineligible share or organizational type to an eligible type do not need to trade on an eligible U.S. exchange
for 12 months before being considered for addition.

&nbsp;&nbsp;&nbsp;&nbsp;· *Sector Classification.* Sector balance, as measured by a comparison
of each GICS<sup>®</sup> sector's weight in the applicable S&P U.S. Index with its weight in the S&P Total Market Index,
in the relevant market capitalization range, is also considered in the selection of companies for the S&P U.S. Indices. The S&P

Total Market Index is a float-adjusted, market capitalization-weighted index designed to track the broad equity market, including large-, mid-, small- and micro-cap stocks.

Current constituents of an S&P U.S. Index can be migrated from one S&P U.S. Index to another provided they meet the total company level market capitalization eligibility criteria for the new index. Migrations from an S&P U.S. Index to another do not need to meet the financial viability, liquidity or 50% of the respective index's total company level minimum market capitalization threshold criteria.

Companies that are spun-off from current index constituents do not need to meet the outside addition criteria, but they should be considered U.S. domiciled for index purposes and have a total market cap representative of the relevant S&P U.S. Index.

**Calculation of the S&P U.S. Indices**

The S&P U.S. Indices are float-adjusted market capitalization-weighted indices. On any given day, the index value of each S&P U.S. Index is the total float-adjusted market capitalization of that S&P U.S. Index's constituents *divided* by its divisor. The float-adjusted market capitalization reflects the price of each stock in the relevant S&P U.S. Index *multiplied* by the number of shares used in the index value calculation.

*Float Adjustment.* Float adjustment means that the number of shares outstanding is reduced to exclude shares that are held by other publicly traded companies, government agencies or certain types of strategic shareholders from the calculation of the index value because such shares are not available to investors. The goal of float adjustment is to adjust each company's total shares outstanding for long-term strategic shareholders, who often have interests such as maintaining control rather than securing the shorter-term economic fortunes of the company. Generally, these long-term strategic shareholders include, but are not limited to, officers and directors, private equity, venture capital and special equity firms, asset managers and insurance companies with direct board of director representation, other publicly traded companies that hold shares, holders of restricted shares, company-sponsored employee share plans/trusts, defined contribution plans/savings, and investment plans, foundations or family trusts associated with the company, government entities at all levels (other than government retirement/pension funds), sovereign wealth funds and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. Restricted shares are generally not included in total shares outstanding except for shares held as part of a lock-up agreement. Shares that are not considered outstanding are also not included in the available float. These generally include treasury stock, stock options, equity participation units, warrants, preferred stock, convertible stock and rights.

For each component, S&P Dow Jones calculates an IWF, which represents the portion of the total shares outstanding that are considered part of the public float for purposes of the relevant S&P U.S. Index.

*Divisor.* Continuity in index values of each S&P U.S. Indices is maintained by adjusting its divisor for all changes in its constituents' share capital after its base date. This includes additions and deletions to the relevant S&P U.S. Index, rights issues, share buybacks and issuances and non-zero price spin-offs. The value of each S&P U.S. Index's divisor over time is, in effect, a chronological summary of all changes affecting the base capital of that S&P U.S. Index. The divisor of each S&P U.S. Index is adjusted such that the index value of that S&P U.S. Index at an instant just prior to a change in base capital equals the index value of that S&P U.S. Index at an instant immediately following that change.

**Maintenance** **of the S&P U.S. Indices**

Changes to index composition are made on an as-needed basis. There is no scheduled reconstitution. Rather, changes in response to corporate actions and market developments can be made at any time. Index additions and deletions are typically 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 Dow Jones's U.S. index committee.

*Deletion from an S&P U.S. Index.* Deletions from an S&P U.S. Index occur as follows:

&nbsp;&nbsp;&nbsp;&nbsp;· A company is deleted from an S&P U.S. Index if it is involved in a merger,
acquisition or significant restructuring such that it no longer meets the eligibility criteria. A company delisted as a result of a merger,

acquisition or other corporate action is removed at a time announced by S&P Dow Jones, normally at the close of the last day of trading or expiration of a tender offer. Constituents that are halted from trading may be kept in the applicable S&P U.S. Index until trading resumes, at the discretion of S&P Dow Jones's U.S. index committee. If a stock is moved to the pink sheets or the bulletin board, the stock is removed.

&nbsp;&nbsp;&nbsp;&nbsp;· A company that substantially violates one or more of the eligibility criteria
may be deleted at the S&P Dow Jones's U.S. index committee's discretion.

Any company that is removed from an S&P U.S. Index (including discretionary and bankruptcy/exchange delistings) must wait a minimum of one year from its removal date before being screened for the eligibility criteria.

S&P Dow Jones believes turnover in index membership should be avoided when possible. At times a stock included in an S&P U.S. Index may appear to temporarily violate one or more of the addition criteria. However, the addition criteria are for addition to an S&P U.S. Index, not for continued membership. As a result, an S&P U.S. Index constituent that appears to violate criteria for addition to that index is not deleted unless ongoing conditions warrant an index change. When a stock is removed from an S&P U.S. Index, S&P Dow Jones explains the basis for the removal.

*Share Updates.* Share counts are updated to the latest publicly available filings on a quarterly basis.

*Investable Weight Factor (IWF) Updates.* IWF changes are implemented either annually, quarterly or on an accelerated schedule following the relevant event depending on the nature of the change as explained below.

&nbsp;&nbsp;&nbsp;&nbsp;· *Annual Review.* IWFs are reviewed annually based on the most recently
available data filed with various regulators and exchanges.

&nbsp;&nbsp;&nbsp;&nbsp;· *Quarterly Review.* IWF changes will be made at the quarterly review
only if the change represents at least 5% of total current shares outstanding and if the adjusted IWF absolute change is at least 5%,
with IWF adjustments limited to the extent necessary to help reflect the corresponding share change.

&nbsp;&nbsp;&nbsp;&nbsp;· *Mandatory Action.* Certain mandatory actions, such as M&A driven
share/IWF changes, stock splits, and mandatory distributions, are not subject to a minimum threshold for implementation. In order to minimize
index turnover, any IWF changes resulting from such mandatory actions are implemented based on the pre-event IWFs of the securities involved.

&nbsp;&nbsp;&nbsp;&nbsp;· *Accelerated Implementation Rule.* Material share/IWF changes resulting
from certain non-mandatory corporate actions follow an accelerated implementation rule with sufficient advance notification. The accelerated
implementation rule is intended to reduce turnover intra-quarter while also enhancing opportunities for index trackers to take advantage
of non-mandatory material liquidity events.

*Share/IWF Reference Date and Freeze Period.* 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 rule. The freeze period begins after the market close on the Tuesday prior to the second Friday of each rebalancing month (*i.e.*, March, June, September and December) and ends after the market close on the third Friday of the rebalancing month.

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. 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.

Companies that are the target of cash M&A events, and if publicly available guidance indicates the event is expected to close by quarter end, may have their share count frozen at their current level for rebalancing purposes.

*Other Adjustments.* In cases where there is no achievable market price for a stock being deleted, it can be removed at a zero or minimal price at the S&P Dow Jones's U.S. index committee's discretion.

*Corporate Action Adjustments.* The table below summarizes the treatment of certain corporate actions.

---

| | |
|:---|:---|
| **Corporate Action**  | **Treatment**  |
| **Company <br> addition/deletion** | <u>Addition</u><br>Companies are added at the float market capitalization weight. The net change to the market capitalization of the relevant S&P U.S. Index causes a divisor adjustment.<br><u>Deletion</u><br>The weights of all stocks in the relevant S&P U.S. Index will proportionally change. Relative weights will stay the same. The index divisor will change due to the net change in the market capitalization of that S&P U.S. Index.<br>|
| **Change in shares<br> outstanding** | Increasing (decreasing) the shares outstanding increases (decreases) the market capitalization of the relevant S&P U.S. Index. The change to the market capitalization of that S&P U.S. Index causes a divisor adjustment. |
| **Split/reverse split** | Shares outstanding are adjusted by the split ratio. Stock price is adjusted by the split ratio. There is no change to the market capitalization of the relevant S&P U.S. Index and no divisor adjustment. |
| **Spin-off** | Generally, the spin-off is added to the relevant S&P U.S. Index on the ex-date at a price of zero and will remain in that S&P U.S. Index for at least one trading day. As a result, there will be no change to the index divisor on the ex-date. <br>However, if the spin-off is ineligible for continued inclusion, it will be removed after the ex-date. The weight of the spin-off being deleted is reinvested across all the index components proportionally such that the relative weights of all index components are unchanged. The net change in the market capitalization of the relevant S&P U.S. Index will cause a divisor change.<br>|
| **Change in IWF** | Increasing (decreasing) the IWF increases (decreases) the market capitalization of the relevant S&P U.S. Index. A net change to the market capitalization of that S&P U.S. Index causes a divisor adjustment. |
| **Ordinary dividend** | When a company pays an ordinary cash dividend, the relevant S&P U.S. Index does not make any adjustments to the price or shares of the stock. As a result, there are no divisor adjustments to that S&P U.S. Index. |
| **Special dividend** | The stock price is adjusted by the amount of the dividend. The net change to the market capitalization of the relevant S&P U.S. Index causes a divisor adjustment. |
| **Rights offering** | All rights offerings that are in the money on the ex-date are applied under the assumption that the rights are fully subscribed. The stock price is adjusted by the value of the rights and the shares outstanding are increased by the rights ratio. The net change in the market capitalization of the relevant S&P U.S. Index causes a divisor adjustment. |

---

**Governance of the S&P U.S. Indices**

The S&P U.S. Indices are maintained by S&P Dow Jones's U.S. index committee. All index committee members are full-time professional members of S&P Dow Jones's staff. At each meeting, the index committee reviews pending corporate actions that may affect index constituents, statistics comparing the composition of the S&P U.S. Indices to the market, companies that are being considered as candidates for addition to an S&P U.S. Index and any significant market events. In addition, the index committee may revise index policies.

**The STOXX Benchmark Ind**ices**

All information contained in this underlying supplement regarding the STOXX<sup>®</sup> Europe Total Market Index, the STOXX<sup>®</sup> Europe 600 Index, the EURO STOXX<sup>®</sup> Index, the STOXX<sup>®</sup> Europe 600 Supersector indices, the EURO STOXX<sup>®</sup> Supersector indices, the STOXX<sup>®</sup> Europe 50 Index and the EURO STOXX 50<sup>®</sup> Index (each, a "**STOXX Benchmark Index**" and collectively, the "**STOXX Benchmark Indices**"), including, without limitation, their make-up, method of calculation and changes in their components, has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, STOXX Limited, a wholly owned subsidiary of Deutsche Börse AG. The STOXX Benchmark Indices are calculated, maintained and published by STOXX Limited. STOXX Limited has no obligation to continue to publish, and may discontinue the publication of, any of the STOXX Benchmark Indices.

**The STOXX<sup>®</sup>** **Europe Total Market Index**

The STOXX<sup>®</sup> Europe Total Market Index is a free float market capitalization-weighted index composed of at least 95% of the free float market capitalization traded on the major exchanges of 17 European countries: Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom. The euro price return version of the STOXX<sup>®</sup> Europe Total Market Index is reported by Bloomberg L.P. under the ticker symbol "BKXP."

Only common stocks and equities with similar characteristics from financial markets that provide reliable real-time, historical component and currency pricing, and reference and corporate actions data are eligible for inclusion in the STOXX<sup>®</sup> Europe Total Market Index. In addition, only listed companies on a regulated market on a major exchange as determined by STOXX are eligible to be included in the STOXX<sup>®</sup> Europe Total Market Index. Investment instruments (Industry Classification Benchmark: 30204000 or 30205000) and companies that were recently removed from the STOXX<sup>®</sup> Europe Total Market Index due to mergers and acquisition are not eligible for inclusion in the STOXX<sup>®</sup> Europe Total Market Index.

Each stock is uniquely assigned to a specific country and listing within the STOXX investable universe. The country classification and listing are generally based on the country of incorporation and the primary listing of the stock. American and other depositary receipts (e.g., ADRs/GDRs) are assigned to the same country as the stock on which the receipt is issued. Each country is assigned to one or more regions. The STOXX<sup>®</sup> Europe Total Market Index is composed of stocks assigned to countries within the Europe region.

All stocks in the investable stock universe of each country included in STOXX<sup>®</sup> Europe Total Market Index are ranked in terms of their free float market capitalization at the cut-off date to produce the review list. The largest companies in the investible universe of each country with a cumulative free float market capitalization up to and including 93% of the investible universe of that country, qualify for inclusion in the STOXX<sup>®</sup> Europe Total Market Index. The stocks covering the next 2% of cumulative free float market capitalization are selected among the largest remaining current components of the STOXX<sup>®</sup> Europe Total Market Index representing the portion of capitalization above 93% and up to and including 99%. If the country coverage is still below the defined threshold, then the largest remaining stocks are selected until the country coverage is reached.

No weighting cap factor (see "—STOXX Benchmark Index Calculation" below) is applied in calculating the STOXX<sup>®</sup> Europe Total Market Index.

**The** **STOXX<sup>®</sup> Europe 600 Index**

The STOXX<sup>®</sup> Europe 600 Index is a free float market capitalization-weighted index composed of 600 of the largest stocks in terms of free float market capitalization traded on the major exchanges of 17 European countries: Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom. At any given time, some eligible countries may not be represented in the STOXX<sup>®</sup> Europe 600 Index. The euro price return version of the STOXX<sup>®</sup> Europe 600 Index is reported by Bloomberg L.P. under the ticker symbol "SXXP."

The selection list for the STOXX<sup>®</sup> Europe 600 Index is composed of the most liquid stock of each component of the STOXX<sup>®</sup> Europe Total Market Index that has a minimum liquidity of greater than one million EUR measured

over 3-month average daily trading value. From the selection list, the largest 550 stocks qualify for inclusion in the STOXX<sup>®</sup> Europe 600 Index. The remaining 50 stocks are selected from the largest remaining current components ranked between 551 and 750. If the number of stocks selected is still below 600, the largest remaining stocks are selected until there are enough stocks.

The weighting cap factor (see "—STOXX Benchmark Index Calculation" below) limits the weight of each component stock within the STOXX<sup>®</sup> Europe 600 Index to a maximum of 20% at the time of each review.

**The EURO STOXX<sup>®</sup> Index**

The EURO STOXX<sup>®</sup> Index is a free float market capitalization weighted-index composed of the largest stocks in terms of free float market capitalization traded on the major exchanges of 11 Eurozone countries: Austria, Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Portugal and Spain. At any given time, some eligible countries may not be represented in the EURO STOXX<sup>®</sup> Index. The euro price return version of the EURO STOXX<sup>®</sup> Index is reported by Bloomberg L.P. under the ticker symbol "SXXE."

The EURO STOXX<sup>®</sup> Index is composed of all of the components of the STOXX<sup>®</sup> Europe 600 Index that are traded in euros and assigned to countries in the Eurozone.

The weighting cap factor (see "—STOXX Benchmark Index Calculation" below) limits the weight of each component stock within the EURO STOXX<sup>®</sup> Index to a maximum of 20% at the time of each review.

**The** **STOXX<sup>®</sup> Europe 600 Supersector Indices and the EURO STOXX<sup>®</sup> Supersector Indices** 

The STOXX<sup>®</sup> Europe 600 Index and the EURO STOXX<sup>®</sup> Index are each divided into 20 supersector indices according to the Industry Classification Benchmark ("**ICB**"), an international system for categorizing companies that is maintained by FTSE Russell. Each supersector index includes the components of its parent index that have been issued by companies within the relevant ICB supersector. The ICB supersectors are: automobiles and parts; banks; basic resources; chemicals; construction and materials; consumer products and services; energy; financial services; food, beverage and tobacco; health care; industrial goods and services; insurance; media; personal care, drug and grocery stores; real estate; retailers; technology; telecommunications; travel and leisure; and utilities.

The STOXX<sup>®</sup> Europe 600 Banks Index is one of 20 STOXX<sup>®</sup> Europe 600 Supersector indices and includes stocks composing the STOXX<sup>®</sup> Europe 600 Index that have been issued by companies in the ICB banks supersector. The banks supersector tracks companies providing a broad range of banking services, including retail banking, loans and money transmissions. The euro price return version of the STOXX<sup>®</sup> Europe 600 Banks Index is reported by Bloomberg L.P. under the ticker symbol "SX7P."

The EURO STOXX<sup>®</sup> Banks Index is one of 20 EURO STOXX<sup>®</sup> Supersector indices and includes stocks composing the EURO STOXX<sup>®</sup> Index that have been issued by companies in the ICB banks supersector.

With respect to each STOXX<sup>®</sup> Europe 600 Supersector index, the weighting cap factor (see "— STOXX Benchmark Index Calculation" below) limits the weight of the highest weighted component stock to a maximum of 30% at the time of each review and limits the weight of the second highest weighted component stock to a maximum of 15% at the time of each review. An intra-quarter capping will be triggered if the largest company exceeds 35% or the second largest company exceeds 20%. No weighting cap factor is applied in calculating the EURO STOXX<sup>®</sup> Supersector indices.

**The** **STOXX<sup>®</sup> Europe 50 Index**

The STOXX<sup>®</sup> Europe 50 Index is a free float market capitalization-weighted index composed of 50 of the largest stocks in terms of free float market capitalization traded on the major exchanges of 17 European countries: Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom. At any given time, some eligible countries

may not be represented in the STOXX<sup>®</sup> Europe 50 Index. The euro price return version of the STOXX<sup>®</sup> Europe 50 Index is reported by Bloomberg L.P. under the ticker symbol "SX5P."

The selection list for the STOXX<sup>®</sup> Europe 50 Index is composed of the components of the STOXX<sup>®</sup> Europe 600 Index. For each of the 20 STOXX<sup>®</sup> Europe 600 Supersector indices, the stocks are ranked in terms of free float market capitalization. The largest stocks are added to the selection list for the STOXX<sup>®</sup> Europe 50 Index until the coverage is close to, but less than, 60% of the free float market capitalization of each of the 20 STOXX<sup>®</sup> Europe 600 Supersector indices. If the next highest-ranked stock brings the coverage closer to 60% in absolute terms, then it is also added to the selection list. All current stocks in the STOXX<sup>®</sup> Europe 50 Index are then added to the selection list. All the stocks on the selection list are ranked in terms of free float market capitalization. The largest 40 stocks on the selection list are selected for inclusion in the STOXX<sup>®</sup> Europe 50 Index; the remaining 10 stocks are selected from the largest remaining current stocks ranked between 41 and 60. If the number of stocks selected is still below 50, then the largest remaining stocks are selected until there are 50 stocks.

The weighting cap factor (see "—STOXX Benchmark Index Calculation" below) limits the weight of each component stock within the STOXX<sup>®</sup> Europe 50 Index to a maximum of 10% at the time of each review.

**The EURO STOXX 50<sup>®</sup> Index**

The EURO STOXX 50<sup>®</sup> Index is a free float market capitalization-weighted index composed of 50 of the largest stocks in terms of free float market capitalization traded on the major exchanges of 9 Eurozone countries: Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands and Spain. At any given time, some eligible countries may not be represented in the EURO STOXX 50<sup>®</sup> Index. The euro price return version of the EURO STOXX 50<sup>®</sup> Index is reported by Bloomberg L.P. under the ticker symbol "SX5E."

The selection list for the EURO STOXX<sup>®</sup> 50 Index is composed of the components of the EURO STOXX<sup>®</sup> Index. For each of the 20 EURO STOXX<sup>®</sup> Supersector indices, the stocks are ranked in terms of free float market capitalization. The largest stocks are added to the selection list until the coverage is close to, but less than, 60% of the free float market capitalization of each of the 20 EURO STOXX<sup>®</sup> Supersector indices. If the next highest-ranked brings the coverage closer to 60% in absolute terms, then it is also added to the selection list. All current EURO STOXX<sup>®</sup> 50 Index stocks are then added to the selection list. All the stocks on the selection list are ranked in terms of free float market capitalization. The largest 40 stocks on the selection list are selected for inclusion in the EURO STOXX<sup>®</sup> 50 Index; the remaining 10 stocks are selected from the largest remaining current stocks ranked between 41 and 60. If the number of stocks selected is still below 50, then the largest remaining stocks are selected until there are 50 stocks.

The weighting cap factor (see "STOXX Benchmark Index Calculation" below) limits the weight of each component stock within the EURO STOXX<sup>®</sup> 50 Index to a maximum of 10% at the time of each review.

**STOXX Benchmark Index Maintenance**

The composition of each of the STOXX<sup>®</sup> Europe Total Market Index, the STOXX<sup>®</sup> Europe 600 Index, the EURO STOXX<sup>®</sup> Index, the STOXX<sup>®</sup> Europe 600 Supersector Indices and the EURO STOXX<sup>®</sup> Supersector Indices is reviewed quarterly in March, June, September and December. For the STOXX<sup>®</sup> Europe Total Market Index, the review cut-off date is the last trading day of the month following the last quarterly index review. For the remaining STOXX Benchmark Indices, the review cut-off date is the last trading day of the month preceding the review month.

The composition of each of the STOXX<sup>®</sup> Europe 50 Index and the EURO STOXX 50<sup>®</sup> Index is reviewed annually in September. The review cut-off date is the last trading day of August. The composition of these STOXX Benchmark Indices is also reviewed monthly and components that rank 75 or below of the current review month and previous review month are replaced and non-component stocks that rank 25 or above are added.

In addition, changes to country classification are effective as of the next quarterly review. At that time, the relevant STOXX Benchmark Index is adjusted accordingly to remain consistent with its country membership rules by deleting the company where necessary.

The STOXX Benchmark Indices are also reviewed on an ongoing basis. Corporate actions (including initial public offerings, mergers and takeovers, spin-offs, delistings, bankruptcy, and price and share adjustments) that affect a STOXX Benchmark Index composition are immediately reviewed. Any changes are announced, implemented and effective in line with the type of corporate action and the magnitude of the effect.

With respect to the STOXX<sup>®</sup> Europe Total Market Index, removed companies are not replaced. With respect to the STOXX<sup>®</sup> Europe 600 Index, the EURO STOXX<sup>®</sup> Index, the STOXX<sup>®</sup> Europe 600 Supersector Indices, the EURO STOXX<sup>®</sup> Supersector Indices, the STOXX<sup>®</sup> Europe 50 Index and the EURO STOXX 50<sup>®</sup> Index, to maintain the number of components constant, a removed company is replaced by the highest-ranked non-component on the relevant selection list. The selection list is updated on a monthly basis according to the review component selection process.

The free float factor for each component stock used to calculate each STOXX Benchmark Index is reviewed, calculated and implemented on a quarterly basis and is fixed until the next quarterly review.

**STOXX Benchmark Index Calculation**

Each STOXX Benchmark Index is calculated with the "Laspeyres formula," which measures the aggregate price changes in the component stocks against a fixed base quantity weight. The formula for calculating the value of a STOXX Benchmark Index can be expressed as follows:

Index = <u>Free-float market capitalization of the relevant STOXX Benchmark Index</u> <br> divisor

The "free float market capitalization of the relevant STOXX Benchmark Index" is equal to the sum of the products, for each component stock, of the price, number of shares, free float factor, weighting cap factor and, if applicable, the exchange rate from the local currency into the index currency of the relevant STOXX Benchmark Index as of the time that STOXX Benchmark Index is being calculated.

The free float factor of each component stock is intended to reduce the number of shares to the actual amount available on the market. All fractions of the total number of shares that are larger than or equal to 5% and whose holding is of a long-term nature are excluded from the calculation of the STOXX Benchmark Indices, including: cross-ownership (stock owned either by the company itself, in the form of treasury shares, or owned by other companies); government ownership (stock owned by either governments or their agencies); private ownership (stock owned by either individuals or families); and restricted shares that cannot be traded during a certain period or have a foreign ownership restriction. Block ownership is not applied for holdings of custodian nominees, trustee companies, mutual funds, investment companies with short-term investment strategies, pension funds and similar entities.

Each STOXX Benchmark Index is also subject to a divisor, which is adjusted to maintain the continuity of the values of that STOXX Benchmark Index despite changes due to corporate actions. Changes in weights due to corporate actions are distributed proportionally across all stock components of the relevant STOXX Benchmark Index. The following is a summary of the adjustments to any component stock of a STOXX Benchmark Index made for corporate actions and the effect of such adjustment on the divisor of that STOXX Benchmark Index, where shareholders of the component stock will receive "B" number of shares for every "A" share held (where applicable). All corporate actions and dividends are implemented at the effective date (ex-date).

**(1) Special cash dividend:**<br>Cash distributions that are outside the scope of the regular dividend policy or that the company defines as an extraordinary distribution<br>New adjusted price = closing price on the day before the effective date – dividend announced by the company × (1 – withholding tax if applicable) <br>

**The Swiss Market Index**

All information contained in this underlying supplement regarding the Swiss Market Index (the "SMI<sup>®</sup>"), 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, SIX Swiss Exchange Ltd ("**SSE**"). The SMI<sup>®</sup> is calculated, maintained and published by SSE. SSE has no obligation to continue to publish, and may discontinue the publication of, the SMI<sup>®</sup>.

The SMI<sup>®</sup> is a free float-adjusted market capitalization-weighted price return index of the Swiss equity market. The SMI<sup>®</sup> was standardized on June 30, 1988 with an initial baseline value of 1,500 points. The SMI<sup>®</sup> is reported by Bloomberg L.P. under the ticker symbol "SMI."

**Composition of the SMI<sup>®</sup>**

The SMI<sup>®</sup> is composed of the most highly capitalized and liquid stocks of the Swiss Performance Index ("SPI<sup>®</sup>"). The SMI<sup>®</sup> represents more than 75% of the free float market capitalization of the Swiss equity market.

The SMI<sup>®</sup> is composed of the 20 highest ranked securities of the SPI<sup>®</sup>, where the ranking of each security is determined by a combination of the following criteria:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· average free float market capitalization over the last 12 months (compared
to the capitalization of the entire SPI<sup>®</sup>); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· cumulated on order book turnover over the last 12 months (compared to the
total turnover of the SPI<sup>®</sup>).

The average market capitalization in percent and the turnover in percent are each given a weighting of 50% and yield the weighted market share. A security is excluded from the SMI<sup>®</sup> if it ranked 23 or lower in the selection list. To reduce fluctuations in the SMI<sup>®</sup>, a buffer is applied for securities ranked 19 to 22. Out of the candidates from ranks 19 to 22, current components are selected with priority over the other candidates. New components out of the buffer are selected until 20 components have been reached. Instruments that are primary listed on more than one stock exchange and generate less than 50% of their total turnover at SIX Swiss Exchange, need to fulfill additional liquidity criteria in order to be selectable for the SMI<sup>®</sup>. For this purpose, all components of the SPI<sup>®</sup> are ranked based on their cumulated order book turnover over the past 12 months relative to the total turnover of the index universe. For this list, only turnovers of stock exchanges are considered where the instrument is primary listed. Such an instrument with several primary listings must rank among the first 18 components on the order book turnover list in order to be selectable for the SMI<sup>®</sup>. Such an instrument is excluded from the SMI<sup>®</sup> once it reaches 23 or lower.

**Standards for Admission and Exclusion**

To ensure that the composition of the SMI<sup>®</sup> maintains a high level of continuity, the stocks contained within it are subject to a special admission and exclusion procedure. This is based on the criteria of free float market capitalization and liquidity. The index-basket adjustments which arise from this procedure are, as a rule, made once per year.

The securities included in the SMI<sup>®</sup> are weighted according to their free float. The free float is calculated only for shares with voting rights. This means that large positions in a security that reach or exceed the threshold of 5% and are held in firm hands are subtracted from the total market capitalization. The following positions in a security are deemed to be held in firm hands:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Shareholding that has been acquired by one person or a group of persons who
are subject to a shareholder or lockup agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Shareholding that has been acquired by one person or a group of persons who
according to publicly known facts, have a long-term interest in a company.

The free float is calculated on the basis of outstanding shares. Issued and outstanding equity capital is, as a rule, the total amount of equity capital that has been fully subscribed, wholly or partially paid in and documented in the Commercial Registry. Neither conditional nor approved capital is counted as issued and outstanding equity capital. The free float is calculated on the basis of listed shares only. Where a company has different categories of listed participation rights, these are considered separately for the free float calculation.

*Exceptions*

The positions in a security held by institutions of the following kind are deemed free floating:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· custodian nominees

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· trustee companies

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· investment funds

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· pension funds

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· investment companies

The SIX Swiss Exchange classifies at its own discretion persons and groups of persons who, because of their area of activity or the absence of important information, cannot be clearly assigned.

*Ordinary Index Review*

Each year on the third Friday of September, the composition of the SMI<sup>®</sup> is updated in the ordinary index review based on the selection list of June. With the cut-off dates on March 31, September 30 and December 31, a provisional selection list is created, which serves as the basis for the adjustment of extraordinary corporate actions. The number of securities and free float shares are adjusted on four ordinary adjustment dates a year: the third Friday in March, June, September and December.

*Extraordinary Corporate Actions*

An extraordinary corporate action is an initial public offering ("**IPO**"), merger and acquisition activity, spin-off, insolvency or any other event that leads to a listing or delisting. An extraordinary corporate action has an ex-date, but its effect can usually not be calculated by a generic predefined formula. In most cases, an extraordinary corporate action leads to a new listing or delisting and subsequently there is a change in the composition of the SMI<sup>®</sup> and in the component weights of the composition of the SMI<sup>®</sup>.

Newly listed instruments that fulfill the selection rules of the SMI<sup>®</sup>, are extraordinarily included in the SMI<sup>®</sup> on their second trading day and the SMI<sup>®</sup> is adjusted with the free float market capitalization at the close of the first trading day. The extraordinary inclusion of a newly listed instrument in the SMI<sup>®</sup> can lead to an extraordinary replacement of an existing index component. Extraordinary inclusions are usually implemented after a notification period of 5 trading days. The adjusted cap factors are implemented after a notification period of generally 5 trading days, but no less than one trading day.

If an IPO of a real estate instrument leads to an extraordinary inclusion, it is included in the SMI<sup>®</sup> in three equal stages. This is achieved by the gradual increase of the number of shares or the free float factor over three trading days starting on the second trading day.

In case of a planned delisting, the exclusion of an index component is made, if possible, on the next ordinary index review date on the third Friday of March, June, September or December. However, if the delisting would be effective before the ordinary index review, the component is excluded from the SMI<sup>®</sup> on the effective date of the delisting. If the index component no longer meets the criteria for remaining in the SMI<sup>®</sup> due to a pending acquisition, it may be removed ahead of time. If a component is excluded from the SMI<sup>®</sup> outside of the ordinary index review, it is replaced by the best-ranked candidate on the selection list that is not yet part composition of the SMI<sup>®</sup> in order to maintain a stable number of components within the SMI<sup>®</sup>. Extraordinary exclusions and respective additions are implemented after a notification period of usually 5 trading days. Adjusted cap factors are implemented after a notification period of generally 5 trading days, but no less than one trading day.

Extraordinary inclusions in the SMI<sup>®</sup> take place if the selection rules for the SMI<sup>®</sup> are fulfilled after a three-month period. This occurs on a quarterly basis after the close of trading on the third Friday of March, June, September and December as follows:

---

| | |
|:---|:---|
| **Latest Listing Date**  | **Earliest Extraordinary Acceptance Date**  |
| 5 trading days prior to the end of November | March |
| 5 trading days prior to the end of February | June |
| 5 trading days prior to the end of May | September |
| 5 trading days prior to the end of August | December |

---

In the case of major market changes as a result of a corporate action, an instrument may be admitted to the SMI<sup>®</sup> outside of the accepted admission period as long as it clearly fulfills the selection rules for the SMI<sup>®</sup>. For the same reasons, a component can be excluded if the requirements for admission to the SMI<sup>®</sup> are no longer fulfilled.

**Calculation of the SMI<sup>®</sup>**

The SMI<sup>®</sup> is calculated using the Laspeyres method with the weighted arithmetic mean of a defined number of securities issues. The formula for calculating the level of the SMI<sup>®</sup> can be expressed as follows:

Index Level = free float market capitalization of the SMI<sup>®</sup> <br> divisor

The "free float market capitalization of the SMI<sup>®</sup>" is equal to the sum of the products, for each component, of the last-paid price, number of shares, free float factor, capping factor and, if applicable, the current Swiss franc exchange rate as of the time the SMI<sup>®</sup> is being calculated.

The divisor is a technical number used to calculate the SMI<sup>®</sup>. If the market capitalization changes due to a corporate event, the divisor changes while the index level remains the same. The new divisor is calculated on the evening of the day before the corporate event takes effect.

In calculating the SMI<sup>®</sup>, the last available price is taken into account. If no price has been paid on the day of calculation, the previous day's price is used. Only the prices achieved via the electronic order book of the SIX Swiss Exchange are used.

The trading hours for Swiss equities, participation certificates and bonus certificates are determined by the SIX Swiss Exchange. Since the opening phase usually causes strong price fluctuations, the SMI<sup>®</sup> is first calculated two minutes after the start of on order book trading. This index level is called the "open." A closing auction takes place ten minutes before close of trading. At the close of trading, the final closing prices used in calculating the closing level of the SMI<sup>®</sup> are established.

*Component Weighting*

The SMI<sup>®</sup> is weighted by the free float market capitalization of its components. The number of shares and the free float factor are reviewed on a quarterly basis. In the same context, each component of the SMI<sup>®</sup> with a free float market capitalization larger than 18% of the total market capitalization of the SMI<sup>®</sup> is capped to that weight of 18%.

Additionally, the components of the SMI<sup>®</sup> are capped to 18% between two ordinary index reviews as soon as two components exceed a weight of 20% each. If such an intra quarter breach is observed after the close of markets, the new cap factors are calculated so that any component has a maximum weight of 18%. This cap factor is set to be effective after the close of the following trading day.

If an issuer has issued more than one equity instrument (*e.g*., registered shares, bearer shares, participation certificates, bonus certificates), it is possible that one issuer is represented in the SMI<sup>®</sup> with more than one

instrument. In this case, the free float market capitalization of those instruments is cumulated for the calculation of the cap factors. If the cumulated index weight exceeds the 18% threshold, the weight is capped accordingly. The cumulated, capped index weight is distributed proportionally based on the free float market capitalization of those instruments.

**The TOPIX<sup>®</sup> Index**

All information contained in this underlying supplement regarding the Tokyo Stock Price Index, or the TOPIX<sup>®</sup> 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, JPX Market Innovation & Research, Inc. (the "**JPXI**"). The TOPIX<sup>®</sup> Index is calculated, maintained and published by the JPXI. The JPXI has no obligation to continue to publish, and may discontinue the publication of, the TOPIX<sup>®</sup> Index.

The TOPIX<sup>®</sup> Index was developed by the Tokyo Stock Exchange, Inc. (the "TSE"). Publication of the TOPIX<sup>®</sup> Index began on July 1, 1969, based on an initial index value of 100 on January 4, 1968, which was reset at 1,000 on April 1, 1998. The TOPIX<sup>®</sup> Index is computed and published every second via TSE's Market Information System and is reported to securities companies across Japan and available worldwide through computerized information networks. The TOPIX<sup>®</sup> Index is reported by Bloomberg L.P. under the ticker symbol "TPX."

**Composition of the TOPIX<sup>®</sup> Index**

The TOPIX<sup>®</sup> Index is a capped free float-adjusted market capitalization-weighted index of domestic common stocks listed on the TSE covering an extensive portion of the Japanese stock market.

On April 4, 2022, JPXI began revisions to the TOPIX<sup>®</sup> Index in conjunction with the restructuring of the TSE into three new market segments: the Prime Market, the Standard Market and the Growth Market. Prior to April 4, 2022, the component stocks of the TOPIX<sup>®</sup> Index consisted of all Japanese common stocks listed on the First Section of the TSE. Stocks that were components of the TOPIX<sup>®</sup> Index as of April 1, 2022 remained components after the market restructuring, regardless of their new market segment. However, component stocks with tradeable share market capitalization of under JPY 10 billion on the base date of June 20, 2021 were designated as "phased weighting reduction constituents," and their weighting was gradually reduced in ten stages on the last business day of each quarter beginning in October 2022 and ending in January 2025 (with a re-evaluation after the fourth stage). Those component stocks that did not meet re-evaluation after the fourth stage were removed from the TOPIX<sup>®</sup> Index on the last business day of January 2025. As of January 31, 2025, the component stocks of the TOPIX<sup>®</sup> Index include a selection of Japanese common stocks listed on the Prime Market, the Standard Market and the Growth Market of the TSE.

In January 2025, JPXI began the second phase of revisions of the TOPIX<sup>®</sup> Index, introducing a new stock selection process and periodic reviews (as described below). Component stocks that were components of the TOPIX<sup>®</sup> Index as of the last business day of January 2025 remained as its components. However, component stocks that are not selected for continuation under the stock selection process described below in the first periodic review occurring in October 2026 will have their weighting gradually reduced in eight stages on the last business day of each quarter beginning in October 2026 and ending in July 2028. Subject to re-evaluation after the fourth stage, such stocks will be removed from the TOPIX<sup>®</sup> Index on the last business day of July 2028.

**Component Stock Selection Process** 

*Periodic Review*. The component stocks of the TOPIX<sup>®</sup> Index are subject to annual periodic review. A periodic review will be conducted once a year on the last business day of October. The periodic review base date will be the last business day of August. However, the first periodic review will be conducted on the last business day of October 2026 (with a periodic review base date as of the last business day of August 2026), and the second periodic review will be on the last business day of October 2028 (with periodic review base date as of the last business day of August 2028).

*Selection of the Index Universe*. The index universe for the TOPIX<sup>®</sup> Index includes all constuents of the TSE Prime Market Index, the TSE Standard Market Index and the TSE Growth Market Index as of the applicable periodic review base date. However, securities that fall under the following criteria are excluded from the index universe:

&nbsp;&nbsp;&nbsp;&nbsp;· securities designated as "to be delisted" as of the periodic review
base date; and

&nbsp;&nbsp;&nbsp;&nbsp;· securities designated as on "special alert" as of the periodic
review base date.

In addition, securities that are or are likely to be designated as "securities to be delisted" or "securities on special alert" between the periodic review base date and the periodic rebalance date may also be excluded from the index universe.

*Selection of Component Stocks*. Of the securities included in the index universe, securities that meet both the "traded value ratio" and the "free float-adjusted market capitalization" criterion in the below table will be selected as component stocks of the TOPIX<sup>®</sup> Index:

---

| | | | |
|:---|:---|:---|:---|
| | **Indicator** | **Inclusion Criteria** | **Continuation Criteria** |
| Traded value ratio | Annual traded value ratio | 0.2 or more | 0.14 or more |
| Free float-adjusted market capitalization | Percentage of cumulative free float-adjusted market capitalization | Securities in the top 96% | Securities in the top 97% |

---

The continuation criteria will be applied to securities that are constituents as of the periodic review base date, and the inclusion criteria will be applied to securities that are not constituents as of that base date.

*Additions and Deletions of Component Stocks Outside of the Annual Periodic Review.* Constituents will be removed from the TOPIX<sup>®</sup> Index outside of a periodic review if they have been (i) delisted or (ii) designated as "securities to be delisted or "securities on special alert."

Constituents will be added to the TOPIX<sup>®</sup> Index outside of a periodic review if (i) a constituent has been delisted due to a share transfer, merger, share exchange, or company split and the newly created, surviving, parent or succeeding company is listed without delay; (ii) a spin-off from a constituent results in a new listing of the spun-off company between the ex-rights date and the effective date; (iii) a constituent has been delisted due to a share exchange or absorption type merger, and the surviving or parent company is not a constituent; (iv) prior to November 2026, a stock is newly listed or transferred to the Prime Market, with this change taking effect on the last business day of the month following the date of the initial listing or transfer; or (v) beginning in November 2026, a stock is newly listed or transferred to the Prime Market, Standard Market or Growth Market and its free float-adjusted market capitalization exceeds the minimum free float-adjusted market capitalization for stocks included within the cumulative ratio of 95% of the free float-adjusted market capitalization in the periodic review immediately preceding the date of the initial listing, with this change taking effect on the last business day of the month following the date of the initial listing or transfer.

**Calculation of the TOPIX<sup>®</sup> Index**

The TOPIX<sup>®</sup> Index is a capped free float-adjusted market capitalization-weighted index. The TOPIX<sup>®</sup> Index is not expressed in yen, but is presented in terms of points (as a decimal figure), rounded to the nearest one-hundredth. The TOPIX<sup>®</sup> Index is calculated by multiplying 100 by the figure obtained by dividing the current free float-adjusted market value (the current market price per share at the time of the index calculation multiplied by the applicable number of free float-adjusted listed common shares listed at the same instance) (the "**Current Market Value**") by the base market value (i.e., the Current Market Value on the base date) (the "**Base Market Value**").

The calculation of the TOPIX<sup>®</sup> Index can be represented by the following formula:

Index = Current Market Value x 100 <br> Base Market Value

*Individual Constituent Weight Cap.* The upper weighting limit for any one constituent of TOPIX<sup>®</sup> Index is 10%. If an issue's weight calculated by free float-adjusted market capitalization as of the last business day of every

August is over the upper limit, a cap-adjustment factor for adjustment of weight will be applied to said issue on the last business day of October. Even if the weight again exceeds the upper limit due to stock price movements or other reasons, the cap-adjustment factor will not be changed until the last business day of the next October.

*Number of Shares Used for Index Calculation*. The number of shares used in the above calculation is adjusted by multiplying the number of shares listed by a free float weight ("**FFW**") ratio. The FFW ratio is the percentage of listed shares deemed to be available for trading in the public market. The purpose of the FFW ratio is to exclude shares that are deemed to be not available to investors in the public markets. JPXI considers the following to be non-free float shares: shares held by the top 10 major shareholders, treasury and other similar stock (including certain cross-share holdings that have limited voting rights), shares held by board members and other representatives, shares held by other listed companies for investment purposes other than pure investment and other shares deemed by JPXI to unavailable for trading in the market.

*Changes in Number of Shares Used for Index Calculation.* Changes in the number of shares will be made due to changes to the free float weight ratio using the stock price at the end of trading on the business day before the adjustment date. The free float weight ratio assigned to each listed company is reviewed annually, with timings that vary according to the settlement terms of each such listed company. Free float weights may also be subject to extraordinary review in the case of certain corporate actions (e.g., allocation of new shares to a third party, conversion of preferred shares or exercise of subscription warrants, company spin-offs, mergers, acquisitions, take-over bids) and for other reasons JPXI believes appropriate.

In addition, changes in the number of shares will be made for certain other events including: public offering, third-party-allotment, issues to shareholders with payment, exercise of subscription warrants, conversion of preferred stock, cancellation of treasury stock, merger/acquisition, a spin-off by a constituent that results in a new listing of the spun-off company between the ex-rights date and the effective date, sale of shares held by the Government of Japan (Nippon Telegraph and Telephone, Japan Tobacco, Japan Post Holdings and Tokyo Metro only), rights offering (limited to cases where the allotted subscription warrant securities are listed), demerger (absorption-type) and other events for which adjustments are deemed appropriate, such as stock splits.

*Adjustments to Base Market Value.* Whenever the market value of the TOPIX<sup>®</sup> Index changes due to an increase or decrease in constituents, capital increase or similar events other than market fluctuations, the Base Market Value is adjusted with the aim of maintaining continuity. Such events requiring adjustment include the addition or removal of component stocks as well as changes in the number of shares used for index calculation.

The formula for the adjustment is as follows:

---

| | | |
|:---|:---|:---|
| Previous Business Day Market Value | = | (Previous Business Day Market Value ± Adjustment Amount) |
| Pre-Adjustment Base Market Value | = | New Base Market Value after adjustment |

---

*where* Adjustment Amount is equal to the changes in the number of shares included in the calculation of the TOPIX<sup>®</sup> Index *multiplied* by the price of those shares used for the purposes of the adjustment.

Therefore,

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;New Base Market Value | = | Old Base Market Value x<br> (Previous Business Day Market Value ± Adjustment Amount) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;New Base Market Value | = | Previous Business Day Market Value |

---

The Base Market Value remains at the new value until a further adjustment is necessary as a result of another change. As a result of such change affecting the Current Market Value or any stock underlying the TOPIX<sup>®</sup> Index, the Base Market Value is adjusted in such a way that the new value of the TOPIX<sup>®</sup> Index will equal the level of the TOPIX<sup>®</sup> Index immediately prior to such change. No adjustment is made to the Base Market Value, however, in the case of events such as stock splits, gratis allotment of shares (limited to cases where the allotment is of treasury stock) and reverse splits, which theoretically do not affect market value.

Information on the reasons for base market value adjustments, details on the adjustments, adjustment dates and other data is available through TSE's notice system, published daily by TSE based on reports and other information from listed companies.

**Commodity Index Descriptions**

**The Bloomberg Commodity Indices**

**General**

All information contained in this underlying supplement regarding the Bloomberg Commodity Index<sup>℠</sup>, its single-commodity sub-indices and the forward-month version of the Bloomberg Commodity Index<sup>℠</sup> and its single-commodity sub-indices (each, a "**Bloomberg Commodity Index**" and collectively, the "**Bloomberg Commodity Indices**"), including, without limitation, their make-up, methods of calculation and changes in their components, has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, Bloomberg Index Services Limited ("**BISL**" and, collectively with its affiliates, "**Bloomberg**"), which calculates and administers the Bloomberg Commodity Indices. Bloomberg is not involved in the offer of the securities in any way and has no obligation to consider your interests as a holder of the securities. Bloomberg has no obligation to continue to publish, and may discontinue publication of, the Bloomberg Commodity Indices at any time in its sole discretion.

**Overview**

The Bloomberg Commodity Index℠ is designed to be a highly liquid and diversified benchmark for commodity investments. The Bloomberg Commodity Index℠ is currently composed of the prices of twenty-five exchange-traded futures contracts on physical commodities. A futures contract is a bilateral agreement providing for the purchase and sale of a specified type and quantity of a commodity or financial instrument during a stated delivery month for a fixed price. For a general description of the commodity futures markets, see "The Commodity Futures Markets" below. The commodities included in the Bloomberg Commodity Index<sup>℠</sup> for 2026 are as follows: aluminum, cocoa, coffee, copper, corn, cotton, crude oil (WTI and Brent), gold, lead, lean hogs, live cattle, low sulphur gas oil, natural gas, nickel, reformulated gasoline blendstock for oxygen blending gasoline ("**RBOB gasoline**"), silver, soybean meal, soybean oil, soybeans, sugar, ultra-low sulphur diesel ("**ULS diesel**"), wheat (Chicago and KC HRW) and zinc. The Bloomberg Commodity Index<sup>SM</sup> tracks futures contracts that trade on the Chicago Board of Trade ("**CBOT**"), the Chicago Mercantile Exchange ("**CME**"), the Commodities Exchange division of the CME Group ("**COMEX**"), the London Metals Exchange ("**LME**"), the New York Mercantile Exchange ("**NYMEX**"), ICE Futures Europe and ICE Futures U.S. The component weightings are determined primarily based on liquidity data, which is the relative amount of trading activity of a particular commodity, and U.S.-dollar weighted production data, which is used to measure the importance of a commodity to the world economy. The Bloomberg Commodity Index℠ is published by Bloomberg L.P. under the ticker symbols "BCOM" for the excess return version and "BCOMTR" for the total return version.

The single-commodity sub-indices of the Bloomberg Commodity Index℠ follow the methodology of the Bloomberg Commodity Index, except that the calculation of each single-commodity sub-index utilizes the prices of the relevant futures contracts (listed under "— Designated Contracts for Each Commodity") and the relevant Commodity Index Multiplier (determined as described under "— Commodity Index Multipliers"). The single-commodity sub-indices of the Bloomberg Commodity Index℠ are published by Bloomberg L.P. If the securities are linked in whole or in part to a single-commodity sub-index of the Bloomberg Commodity Index, the ticker symbol will be provided in the relevant pricing supplement.

BISL also publishes forward-month versions of the Bloomberg Commodity Index℠ and its single-commodity sub-indices that track longer-dated commodity futures contracts. The Bloomberg Commodity Index 3 Month Forward<sup>SM</sup> follows the methodology of the Bloomberg Commodity Index, except that the futures contracts used for calculating the Bloomberg Commodity Index 3 Month Forward<sup>SM</sup> are advanced, as compared to the Bloomberg Commodity Index, such that the delivery months for the reference contracts are later than those of the corresponding reference contracts used for the Bloomberg Commodity Index. The Bloomberg Commodity Index 3 Month Forward<sup>SM</sup> is published by Bloomberg L.P. under the ticker symbols "BCOMF3" for the excess return version and "BCOMF3T" for the total return version. The forward-month single-commodity sub-indices of the Bloomberg

Commodity Index℠ follow the methodology of the Bloomberg Commodity Index, except that the calculation of each forward-month single-commodity sub-index utilizes the prices of the relevant futures contracts (as listed under "— Designated Contracts for Each Commodity") and the relevant Commodity Index Multiplier (determined as described under "— Commodity Index Multipliers"). In addition, the futures contracts used for calculating the forward-month single-commodity sub-indices are advanced, as compared to the futures contracts included in the Bloomberg Commodity Index, such that the delivery months for the reference contracts are later than those of the corresponding reference contracts used for the single-commodity sub-indices. The forward-month single-commodity sub-indices of the Bloomberg Commodity Index℠ are published by Bloomberg L.P. If the securities are linked in whole or in part to a forward-month single-commodity sub-index of the Bloomberg Commodity Index, the ticker symbol will be provided in the relevant pricing supplement.

BISL publishes both a total return version and excess return version of each of the Bloomberg Commodity Indices. The total return version of each Bloomberg Commodity Index℠ reflects the returns on a fully collateralized investment in the excess return version of such Bloomberg Commodity Index. Accordingly, the total return version of each Bloomberg Commodity Index℠ combines the returns of the relevant excess return version with returns on cash collateral invested in Treasury Bills. The cash collateral returns are calculated using the most recent weekly auction high rate for 13-week (3 Month) U.S. Treasury Bills, as published by the Bureau of the Public Debt of the U.S. Treasury (or any successor source). Weekly auction high rates are generally published once each week on Monday. The securities may be linked to the excess return or the total return version of the Bloomberg Commodity Indices, as specified in the relevant pricing supplement.

**Benchmark Governance, Audit and Review Structure**

BISL uses three primary committees to provide overall governance and oversight of its benchmark administration activities:

The Product & Operations Committee ("**POC**") is responsible for the first line of control over the creation, design, production and dissemination of benchmarks administered by BISL.

The oversight function is provided by Bloomberg's Benchmark Oversight Committee ("**BOC**"). The BOC is independent of the POC and is responsible for reviewing and challenging the BISL Board of Directors ("**Board**") and the POC regarding relevant aspects of the provision of benchmarks by BISL. The BOC has been established by Board and meets at least quarterly. It is composed of at least three voting members, including a chair, who are not directly involved in the provision of any BISL benchmark. Membership of the BOC is based on a combination of seniority, global outlook and diverse experience across Bloomberg L.P's business and operations.

The Risk Committee ("**RiskCo**") advises the Board, the POC and the BOC on BISL's overall risk appetite, tolerance and strategy and oversees BISL's risk exposure and risk strategy.

As described in more detail below, the composition of the Bloomberg Commodity Index<sup>℠</sup> is rebalanced by BISL each year pursuant to the established procedures by index managers operating within the POC governance body under the oversight of the BOC oversight function. Any material deviations or changes from established procedures are subject to review by those bodies. In addition, to the extent practicable, BISL may solicit stakeholder feedback. Once approved, the new composition of the Bloomberg Commodity Index<sup>℠</sup> is publicly announced and takes effect in the January immediately following the announcement.

**Four Main Principles Guiding the Creation of the Bloomberg Commodity Index<sup>℠</sup>**

The Bloomberg Commodity Index<sup>℠</sup> was created using the following four main principles:

&nbsp;&nbsp;&nbsp;&nbsp;· **Economic Significance**. A commodity index should fairly represent the importance of a diversified group of commodities to the world
economy. To achieve a fair representation, the Bloomberg Commodity Index<sup>℠</sup> uses both liquidity data and U.S.
dollar-weighted production data in determining the relative quantities of included commodities. The Bloomberg Commodity Index<sup>℠</sup>
primarily relies on liquidity data, or the relative amount of trading activity of a particular commodity, as an important indicator of
the value placed on that commodity by financial and physical market participants. The Bloomberg Commodity Index<sup>℠</sup>
also relies on production data as a useful measure of the importance of a commodity to the world

economy. Production data alone, however, may underestimate the economic significance of storable commodities (*e.g.*, gold) relative to non-storable commodities (*e.g.*, live cattle). Production data alone also may underestimate the investment value that financial market participants place on certain commodities, and/or the amount of commercial activity that is centered on various commodities. Accordingly, production statistics alone do not necessarily provide as accurate a reflection of economic importance as the pronouncements of the markets themselves. The Bloomberg Commodity Index<sup>℠</sup> thus relies on data that is both endogenous to the futures markets (liquidity) and exogenous to the futures markets (production) in determining relative weightings.

&nbsp;&nbsp;&nbsp;&nbsp;· **Diversification**. A second major goal of the Bloomberg Commodity
Index<sup>℠</sup> is to provide diversified exposure to commodities as an asset class. Disproportionate weighting of
any particular commodity or sector increases volatility and negates the concept of a broad-based commodity index. Instead of
diversified commodities exposure, the investor is unduly subjected to micro-economic shocks in one commodity or sector. As
described further below, diversification rules have been established and are applied annually. Additionally, the Bloomberg
Commodity Index<sup>℠</sup> is rebalanced annually on a price-percentage basis in order to maintain diversified commodities exposure
over time.

&nbsp;&nbsp;&nbsp;&nbsp;· **Continuity**. A third goal of the Bloomberg Commodity Index<sup>℠</sup>
is to be responsive to the changing nature of commodity markets in a manner that does not completely reshape the character of the Bloomberg
Commodity Index<sup>℠</sup> from year to year. The Bloomberg Commodity Index<sup>℠</sup> is intended to provide
a stable benchmark, so that end-users may be reasonably confident that historical performance data (including such diverse measures as
correlation, spot yield, roll yield and volatility) is based on a structure that bears some resemblance to both the current and future
composition of the Bloomberg Commodity Index<sup>℠</sup>.

&nbsp;&nbsp;&nbsp;&nbsp;· **Liquidity**. Another goal of the Bloomberg Commodity Index<sup>℠</sup>
is to provide a highly liquid index. The explicit inclusion of liquidity as a weighting factor helps to ensure that the Bloomberg
Commodity Index<sup>℠</sup> can accommodate substantial investment flows. The liquidity of an index not only affects
transaction costs associated with current investments, but may also affect the reliability of historical price performance data.

These principles represent goals of the Bloomberg Commodity Index<sup>℠</sup>, its creators and owners and there can be no assurance that these goals will be achieved.

**Composition of the Bloomberg Commodity Index<sup>℠</sup>**

*Commodities Available for Inclusion in the Bloomberg Commodity Index<sup>℠</sup>*

The commodities that have been selected for possible inclusion in the Bloomberg Commodity Index<sup>℠</sup> are believed by BISL to be sufficiently significant to the world economy to merit consideration for inclusion in the Bloomberg Commodity Index<sup>℠</sup> and tradable through a qualifying related futures contract (a "**Designated Contract**"). With the exception of several metals contracts (aluminum, lead, tin, nickel and zinc) that trade on the LME and the contracts for Brent crude oil and low sulphur gas oil, which both trade on ICE Futures Europe, each of the potential commodities is currently the subject of at least one futures contract that trades on a U.S. exchange.

The 25 commodities currently available for inclusion in the Bloomberg Commodity Index<sup>℠</sup> are aluminum, cocoa, coffee, copper, corn, cotton, crude oil, gold, lead, lean hogs, live cattle, low sulphur gas oil, natural gas, nickel, platinum, RBOB gasoline, silver, soybean meal, soybean oil, soybeans, sugar, tin, ULS diesel, wheat and zinc.

The commodities selected to be included in the Bloomberg Commodity Index<sup>℠</sup> (each, an "**Index Commodity**" and collectively, the "**Index Commodities**") for 2026 are as follows: aluminum, coffee, copper, corn, cotton, crude oil, gold, lead, lean hogs, live cattle, low sulphur gas oil, natural gas, nickel, RBOB gasoline, silver, soybean meal, soybean oil, soybeans, sugar, ULS diesel, wheat and zinc.

*Designated Contracts for Each Commodity*

One or more futures contracts known as a Designated Contract is selected by BISL for each of the 25 commodities eligible for inclusion in the Bloomberg Commodity Index. Historically, through and including the

composition of the Bloomberg Commodity Index<sup>℠</sup> for 2026, BISL has chosen for each commodity one Designated Contract that is traded in North America and denominated in U.S. dollars (with the exception of several LME contracts, which are traded in London, and with the exception of crude oil, for which two Designated Contracts have been selected starting in 2012, and wheat, for which two Designated Contracts that are traded in North America have been selected starting in 2013).

BISL may in the future select more than one Designated Contract for additional commodities or may select Designated Contracts that are traded outside of the United States or in currencies other than the U.S. dollar. For example, in the event that changes in regulations concerning position limits materially affect the ability of market participants to replicate the Bloomberg Commodity Index<sup>℠</sup> in the underlying futures markets, it may become appropriate to include multiple Designated Contracts for one or more commodities (in addition to crude oil and wheat) in order to enhance liquidity.

The termination or replacement of a futures contract on an established exchange occurs infrequently. If a Designated Contract were to be terminated or replaced, a comparable futures contract would be selected, if available, to replace the Designated Contract.

*Commodity Groups*

For purposes of applying the diversification rules discussed above and below, the commodities available for inclusion in the Bloomberg Commodity Index<sup>℠</sup> are assigned to Commodity Groups. The Commodity Groups, and the commodities included in each Commodity Group, are currently as follows:

---

| | |
|:---|:---|
| **Commodity Group**  | **Commodities**  |
| Energy | WTI Crude Oil <br> Brent Crude Oil <br> Natural Gas <br> RBOB Gasoline <br> Low Sulphur Gas Oil <br> ULS Diesel  |
| Grains | Corn <br> Soybeans <br> Soybean Oil <br> Soybean Meal <br> Wheat (Chicago) <br> Wheat (KC HRW)  |
| Industrial Metals | Aluminum <br> Copper <br> Lead <br> Nickel <br> Tin <br> Zinc  |
| Precious Metals | Gold <br> Platinum <br> Silver  |
| Softs | Cocoa <br> Coffee <br> Cotton <br> Sugar  |
| Livestock | Live Cattle <br> Lean Hogs  |

---

*2026 Bloomberg Commodity Index<sup>℠</sup> Target Weights Breakdown by Commodity and Commodity Group*

The target weights for the commodities included in the Bloomberg Commodity Index<sup>℠</sup> and the target weights for the commodity groups for 2026 are as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Commodity Group**  | **Commodity**  | **Target Weight <br> (approximate)**  | **Target Group Weight <br> (approximate)**  |
| Energy | WTI Crude Oil | 6.64% | 29.44% |
| Energy | Brent Crude Oil | 8.36% | 29.44% |
| Energy | Natural Gas | 7.20% | 29.44% |

*Determination of Relative Weightings*

The first step in constructing the Bloomberg Commodity Index℠ is to determine the relative liquidity and production percentages. The relative weightings of the Index Commodities are determined annually according to both liquidity and U.S. dollar-adjusted production data in 2/3 and 1/3 shares, respectively. Each year, for each Designated Contract selected as a reference contract for a commodity designated for potential inclusion in the Bloomberg Commodity Index, liquidity is measured by the Commodity Liquidity Percentage ("**CLP**") and production by the Commodity Production Percentage ("**CPP**"). The CLP for each Designated Contract is determined by taking a five-year average of the product of trading volume and the historical U.S. dollar value of that Designated Contract, and dividing the result by the sum of such products for all Designated Contracts. The CPP is determined for each commodity by taking a five-year average of annual world production figures, adjusted by the historical U.S. dollar value of the applicable Designated Contract, and dividing the result by the sum of such production figures for all the commodities that were designated for potential inclusion in the Bloomberg Commodity Index. The CLP and the CPP are then combined (using a ratio of 2:1) to establish the Commodity Index Percentage ("**CIP**") for each commodity. This CIP is then adjusted in accordance with the diversification rules to determine the commodities that will be included in the Bloomberg Commodity Index℠ and their respective percentage weights.

For primary commodities that appear in the Bloomberg Commodity Index℠ along with their derivatives (*e.g.*, crude oil, together with ULS diesel, RBOB gasoline and low sulphur gas oil), the CPPs within that group of commodities are reassigned among the primary commodity and its derivative commodities to eliminate the double-counting of production figures for the primary commodity that would otherwise occur if no adjustment were made. The same process is applied when more than one Designated Contract has been selected for a particular commodity.

*Diversification Rules*

The Bloomberg Commodity Index℠ is designed to provide diversified exposure to commodities as an asset class. To ensure that no single commodity or commodity sector dominates the Bloomberg Commodity Index, the following diversification rules are applied to the annual reweighting and rebalancing of the Bloomberg Commodity Index℠ as of January of the applicable year:

&nbsp;&nbsp;&nbsp;&nbsp;· No single commodity (*e.g.*, natural gas or silver) may constitute more
than 15% of the Bloomberg Commodity Index<sup>℠</sup>.

&nbsp;&nbsp;&nbsp;&nbsp;· No single commodity, together with its derivatives (*e.g.*, WTI crude
oil and Brent crude oil, together with ULS diesel, unleaded gas and low sulphur gas oil), may constitute more than 25% of the Bloomberg
Commodity Index<sup>℠</sup>,

&nbsp;&nbsp;&nbsp;&nbsp;· No related group of commodities designated as a Commodity Group (*e.g.*,
energy, precious metals, livestock or grains) may constitute more than 33% of the Bloomberg Commodity Index.

&nbsp;&nbsp;&nbsp;&nbsp;· The CIP for each of gold and silver is set equal to its respective CLP, with
its respective CPP amount allocated among the other commodity sectors.

&nbsp;&nbsp;&nbsp;&nbsp;· No single commodity (*e.g.*, natural gas or silver) may constitute less
than 2% of the Bloomberg Commodity Index<sup>℠</sup>, as liquidity allows.

The last rule helps to increase the diversification of the Bloomberg Commodity Index<sup>℠</sup> by giving even the smallest commodity within the basket a reasonably significant weight. Commodities with small weights initially may have their weights increased to higher than 2% by prior steps.

Following the annual reweighting and rebalancing of the Bloomberg Commodity Index<sup>℠</sup> in January, the percentage of any single commodity or group of commodities at any time prior to the next reweighting or rebalancing will fluctuate and may exceed or be less than the percentages initially established.

*Commodity Index Multipliers*

Following application of the diversification rules discussed above, CIPs are incorporated into the Bloomberg Commodity Index℠ by calculating the new unit weights for each Designated Contract. Near the beginning of each new calendar year, the CIPs, along with the settlement prices determined on that date for Designated Contracts included in the Bloomberg Commodity Index, are used to determine a Commodity Index Multiplier ("**CIM**") for each Designated Contract. This CIM is used to achieve the percentage weightings of the Designated Contracts, in dollar terms, indicated by their respective CIPs. After the CIMs are calculated, they remain fixed throughout the year. As a result, the observed price percentage of each Designated Contract will float throughout the year, until the CIMs are reset the following year based on new CIPs.

**Calculation of the Bloomberg Commodity Index<sup>℠</sup>**

The excess return version of the Bloomberg Commodity Index℠ is calculated by BISL by applying the impact of the changes to the futures prices of commodities included in the Bloomberg Commodity Index℠ (based on their relative weightings). Once the CIMs are determined as discussed above, the calculation of the excess return version of the Bloomberg Commodity Index℠ is a mathematical process whereby the CIMs for the Index Commodities are multiplied by the prices in U.S. dollars for the applicable Designated Contracts. These products are then summed. The percentage change in this sum is then applied to the prior Bloomberg Commodity Index℠ excess return level to calculate the new Bloomberg Commodity Index℠ excess return level.

The total return version of the Bloomberg Commodity Index℠ is calculated by BISL by applying the impact of the changes in the level of the excess return version of the Bloomberg Commodity Index℠ and adding interest that could be earned on funds committed to the trading of the underlying futures contracts. Once the level of the excess return version of the Bloomberg Commodity Index℠ is determined as discussed above, the daily return on a 13-week (3-month) T-bill is added to the percentage change in the excess return version of the Bloomberg Commodity

Index℠ (as compared with the prior Bloomberg Commodity Index℠ excess return level) to obtain the total return. The total return is then applied to the prior Bloomberg Commodity Index℠ total return level to calculate the new Bloomberg Commodity Index℠ total return level.

*The Bloomberg Commodity Index<sup>℠</sup> Is a Rolling Index*

The Bloomberg Commodity Index<sup>℠</sup> is composed of futures contracts on physical commodities. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, commodity futures contracts normally specify a certain date for the delivery of the underlying physical commodity. In order to avoid delivering the underlying physical commodities and to maintain exposure to the underlying physical commodities, futures contracts on physical commodities specifying delivery on a nearby date must be sold and futures contracts on physical commodities that have not yet reached the delivery period must be purchased. The rollover for each contract occurs over a period of five Index Business Days (as defined below) each month according to a pre-determined schedule. This process is known as "rolling" a futures position. The Bloomberg Commodity Index<sup>℠</sup> is a "rolling index."

With respect to the Bloomberg Commodity Indices<sup>SM</sup>, an "**Index Business Day**" is any day on which the sum of the CIPs for those Index Components that are open for trading is greater than 50%. For purposes of this definition, the CIPs used during any calendar year are those calculated in the preceding year and applied on the CIM Determination Date for that year; provided however, that on any day during such calendar year falling prior to or on the CIM Determination Date, the preceding year's CIPs will be used for purposes of determining the existence of an Index Business Day.

**Bloomberg Commodity Index<sup>℠</sup> Calculation Disruption Events**

From time to time, disruptions can occur in trading futures contracts on various commodity exchanges. The daily calculation of the Bloomberg Commodity Index<sup>℠</sup> may be adjusted in the event that BISL determines that any of the following index calculation disruption events exists:

&nbsp;&nbsp;&nbsp;&nbsp;· the termination or suspension of, or material limitation or disruption in,
the trading of any futures contract used in the calculation of the Bloomberg Commodity Index<sup>℠</sup> on that day;

&nbsp;&nbsp;&nbsp;&nbsp;· the settlement price of any futures contract used in the calculation of the
Bloomberg Commodity Index<sup>℠</sup> reflects the maximum permitted price change from the previous day's settlement price;

&nbsp;&nbsp;&nbsp;&nbsp;· the failure of an exchange to publish official settlement prices for any futures

**The Commodity Futures Markets**

Futures contracts on physical commodities are traded on regulated futures exchanges, in the over-the-counter market and on various types of physical and electronic trading facilities and markets. As of the date of this underlying supplement, all of the contracts included in the Bloomberg Commodity Index℠ described in this underlying supplement are exchange-traded futures contracts. An exchange-traded futures contract provides for the purchase and sale of a specified type and quantity of a commodity or financial instrument during a stated delivery month for a fixed price. A futures contract provides for a specified settlement month in which cash settlement is made or in which the commodity or financial instrument is to be delivered by the seller (whose position is therefore described as "short") and acquired by the purchaser (whose position is therefore described as "long").

No purchase price is paid or received on the purchase or sale of a futures contract. Instead, an amount of cash or cash equivalents must be deposited with the broker as "initial margin." This amount varies based on the requirements imposed by the exchange clearinghouses, but it may be lower than 5% of the notional value of the contract. This margin deposit provides collateral for the obligations of the parties to the futures contract.

By depositing margin, which may vary in form depending on the exchange, with the clearinghouse or broker involved, a market participant may be able to earn interest on its margin funds, thereby increasing the total return that it may realize from an investment in futures contracts.

Futures contracts are traded on organized exchanges, known as "contract markets" in the United States. At any time prior to the expiration of a futures contract, a trader may elect to close out its position by taking an opposite position on the exchange on which the trader obtained the position, subject to the availability of a liquid secondary market. This operates to terminate the position and fix the trader's profit or loss. Futures contracts are cleared through the facilities of a centralized clearinghouse and a brokerage firm, referred to as a "futures commission merchant," which is a member of the clearinghouse.

Unlike equity securities, futures contracts, by their terms, have stated expirations at a specified point in time prior to expiration. At a specific point in time prior to expiration, trading in a futures contract for the current delivery month will cease. As a result, a market participant wishing to maintain its exposure to a futures contract on a particular commodity or financial instrument with the nearest expiration must close out its position in the expiring contract and establish a new position in the contract for the next delivery month, a process referred to as "rolling." For example, a market participant with a long position in a futures contract expiring in November who wishes to maintain a position in the nearest delivery month will, as the November contract nears expiration, sell the November contract, which serves to close out the existing long position, and buy a futures contract expiring in December. This will "roll" the November position into a December position, and, when the November contract expires, the market participant will still have a long position in the nearest delivery month.

Futures exchanges and clearinghouses in the United States are subject to regulation by the Commodity Futures Trading Commission. Exchanges may adopt rules and take other actions that affect trading, including imposing speculative position limits, maximum price fluctuations and trading halts and suspensions and requiring liquidation of contracts in certain circumstances.

Futures markets outside the United States are generally subject to regulation by comparable regulatory authorities. The structure and nature of trading on non-U.S. exchanges may differ from this description.

**The S&P GSCI<sup>®</sup> Indices**

All information contained in this underlying supplement regarding the S&P GSCI<sup>®</sup> Indices (as defined below), including, without limitation, their make-up, method of calculation and changes in their 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**"). The S&P GSCI<sup>®</sup> Indices are calculated, maintained and published by S&P Dow Jones. S&P Dow Jones acquired the rights to the S&P GSCI<sup>®</sup> Indices from Goldman, Sachs & Co. in 2007. Goldman, Sachs & Co. established and began calculating the S&P GSCI<sup>®</sup> in April 1991. The former name of the S&P GSCI<sup>®</sup> was the Goldman Sachs Commodity Index, or GSCI<sup>®</sup>. S&P Dow Jones has no obligation to continue to publish, and may discontinue publication of, any S&P GSCI<sup>®</sup> Index.

The securities may be linked in whole or in part to the performance of the S&P GSCI<sup>®</sup> Index ("S&P GSCI<sup>®</sup>"), the S&P GSCI<sup>®</sup> Light Energy Index or certain of the S&P GSCI<sup>®</sup>'s commodity sector sub-indices: the S&P GSCI<sup>®</sup> Agriculture Index, the S&P GSCI<sup>®</sup> Energy Index, the S&P GSCI<sup>®</sup> Industrial Metals Index, the S&P GSCI<sup>®</sup> Livestock Index and the S&P GSCI<sup>®</sup> Precious Metals Index (each a "S&P GSCI<sup>®</sup> Sector Index," and together, the "S&P GSCI<sup>®</sup> Sector Indices"), or the S&P GSCI<sup>®</sup>'s single commodity sub-indices (each a "S&P GSCI<sup>®</sup> Single Component Index," and collectively, the "S&P GSCI<sup>®</sup> Single Component Indices"). The S&P GSCI<sup>®</sup> Single Component Indices and S&P GSCI<sup>®</sup> Sector Indices are referred to in this underlying supplement collectively as the "S&P GSCI<sup>®</sup> Component Indices," and together with the S&P GSCI<sup>®</sup> and the S&P GSCI<sup>®</sup> Light Energy Index, as the "S&P GSCI<sup>®</sup> Indices," and each, an "S&P GSCI<sup>®</sup> Index." If the securities are linked to any S&P GSCI<sup>®</sup> Single Component Index, any relevant disclosure for such S&P GSCI<sup>®</sup> Single Component Index will be provided in the relevant pricing supplement.

S&P Dow Jones publishes excess return and total return versions of each of the S&P GSCI<sup>®</sup> Indices. The relevant pricing supplement will specify whether the securities are linked to the excess return or total return version of the S&P GSCI<sup>®</sup> Indices. The excess return versions of the S&P GSCI<sup>®</sup> Indices are based on price levels of the futures contracts included in that S&P GSCI<sup>®</sup> Index as well as the discount or premium obtained by "rolling" hypothetical positions in those contracts forward as they approach delivery. The total return versions of the S&P GSCI<sup>®</sup> Indices incorporate the returns of the excess return versions, except that the total return versions also reflect interest earned on hypothetical, fully collateralized contract positions on the included commodities.

The S&P GSCI<sup>®</sup> is an index on a world production-weighted basket of principal non-financial commodities (*i.e.*, physical commodities) that satisfy specified criteria. The only commodities represented in the S&P GSCI<sup>®</sup> are those physical commodities on which active and liquid contracts are traded on trading facilities in major industrialized countries. The commodities included in the S&P GSCI<sup>®</sup> are weighted, on a production basis, to reflect the relative significance (in the view of S&P Dow Jones, as described below) of such commodities to the world economy. The fluctuations in the value of the S&P GSCI<sup>®</sup> are intended generally to correlate with changes in the prices of such physical commodities in global markets. The S&P GSCI<sup>®</sup> has been normalized such that its hypothetical level on January 2, 1970 was 100. Futures contracts on the S&P GSCI<sup>®</sup>, and options on such futures contracts, are currently listed for trading on the Chicago Mercantile Exchange.

The S&P GSCI<sup>®</sup> Light Energy Index is composed of the same commodity futures contracts as the S&P GSCI<sup>®</sup> but with those weights for contracts in the energy sector having been divided by 4. Because the weights of energy-related S&P GSCI<sup>®</sup> commodities are reduced in the S&P Light Energy Index relative to the S&P GSCI<sup>®</sup>, the relative weights of the remaining S&P GSCI<sup>®</sup> commodities are necessarily increased. As a result, although the S&P GSCI<sup>®</sup> Light Energy Index contains all of the S&P GSCI<sup>®</sup> commodities that are included in the S&P GSCI<sup>®</sup>, it is not world-production weighted in the same manner as the S&P GSCI<sup>®</sup> and may not serve as a benchmark for changes in inflation or other economic factors. In particular, because of the significance of energy-related commodities to the world economy, a significant reduction in the weights of these commodities in the S&P GSCI<sup>®</sup> Light Energy Index will substantially limit the effect of changes in energy prices on the S&P GSCI<sup>®</sup> Light Energy Index. Increases in the prices of energy commodities, therefore, will not increase the level of the S&P GSCI<sup>®</sup> Light Energy Index to the same extent as the S&P GSCI<sup>®</sup>.

The S&P GSCI<sup>®</sup> Agriculture Index is a world production-weighted index of certain agricultural commodities in the world economy, including wheat (Chicago and Kansas), corn, soybeans, cotton, sugar, coffee and cocoa.

The S&P GSCI<sup>®</sup> Energy Index is a world production-weighted index of certain energy commodities in the world economy, including crude oil, Brent crude oil, RBOB gasoline, heating oil, gasoil and natural gas.

The S&P GSCI<sup>®</sup> Industrial Metals Index is a world production-weighted index of certain industrial metals commodities in the world economy, including aluminum, copper, lead, nickel and zinc.

The S&P GSCI<sup>®</sup> Livestock Index is a world production-weighted index of certain livestock commodities in the world economy, including lean hogs, live cattle and feeder cattle.

The S&P GSCI<sup>®</sup> Precious Metals Index is a world production-weighted index consisting of two precious metals commodities in the world economy: gold and silver.

Set forth below is a summary of the methodology used to calculate the S&P GSCI<sup>®</sup> Indices. Because the S&P GSCI<sup>®</sup> is the base index of the S&P GSCI<sup>®</sup> Component Indices, the methodology for compiling the S&P GSCI<sup>®</sup> relates as well to the methodology of compiling the S&P GSCI<sup>®</sup> Component Indices. Each of the S&P GSCI<sup>®</sup> Component Indices is calculated in the same manner as the S&P GSCI<sup>®</sup>, except that (i) the daily contract reference price, CPWs and roll weights (each as discussed below) used in performing those calculations are limited to those of the commodities included in the relevant S&P GSCI<sup>®</sup> Component Index and (ii) each S&P GSCI<sup>®</sup> Component Index has a separate normalizing constant (discussed below). The methodology for determining the composition and weighting of the S&P GSCI<sup>®</sup> and for calculating its value is subject to modification in a manner consistent with the purposes of the S&P GSCI<sup>®</sup>, as described below. S&P Dow Jones makes the official calculations of the S&P GSCI<sup>®</sup> Indices.

**Composition of the S&P GSCI<sup>®</sup>**

In order to be included in the S&P GSCI<sup>®</sup>, a contract must satisfy the following eligibility criteria:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the contract must be in respect of a physical commodity and not a financial
commodity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the contract must have a specified expiration or term or provide in some other
manner for delivery or settlement at a specified time, or within a specified period, in the future;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the contract must, at any given point in time, be available for trading at
least five months prior to its expiration or such other date or time period specified for delivery or settlement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the contract must be traded on an exchange, facility or other platform (referred
to as a "trading facility") that allows market participants to execute spread transactions, through a single order entry,
between the pairs of contract expirations included in the S&P GSCI<sup>®</sup> that, at any given point in time, will be involved
in the rolls to be effected in the next three roll periods (defined below);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the contract must be denominated in U.S. dollars; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the contract must be traded on or through a trading facility that has its
principal place of business or operations in a country that is a member of the Organization for Economic Cooperation and Development.

The price of the relevant contract that is used as a reference or benchmark by market participants (referred to as the "daily contract reference price") generally must have been available on a continuous basis for at least two years prior to the proposed date of inclusion in the S&P GSCI<sup>®</sup>. In appropriate circumstances, S&P Dow Jones may determine that a shorter time period is sufficient or that historical daily contract reference prices for such contract may be derived from daily contract reference prices for a similar or related contract. The daily contract reference price may be (but is not required to be) the price (a) used by the relevant trading facility or clearing facility to determine the margin obligations (if any) of its members or participants or margining transactions or for other purposes or (b) referred to generally as the reference, closing or settlement price of the relevant contract.

For a contract to be eligible for inclusion in the S&P GSCI<sup>®</sup>, volume data with respect to such contract must be available for at least the three months immediately preceding the date on which the determination is made. The following eligibility criteria apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In order to be added to the S&P GSCI<sup>®</sup>, a contract that
is not included in the S&P GSCI<sup>®</sup> at the time of determination and that is based on a commodity that is not represented
in the S&P GSCI<sup>®</sup> at such time must have an annualized total dollar value traded over the relevant period of at least
U.S. $15 billion. The total dollar value traded is the dollar value of the total quantity of the commodity underlying transactions
in the relevant contract over the period for which the calculation is made, based on the average of the daily contract reference prices
on the last day of each month during the period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In order to continue to be included in the S&P GSCI<sup>®</sup>, a
contract that is already included in the S&P GSCI<sup>®</sup> at the time of determination and that is the only contract on the
relevant commodity included in the S&P GSCI<sup>®</sup> must have an annualized total dollar value traded of at least U.S. $5
billion over the relevant period and of at least U.S. $10 billion during at least one of the three most recent annual periods used in
making the determination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In order to be added to the S&P GSCI<sup>®</sup>, a contract that
is not included in the S&P GSCI<sup>®</sup> at the time of determination and that is based on a commodity on which there are one
or more contracts already included in the S&P GSCI<sup>®</sup> at such time must have an annualized total dollar value traded
over the relevant period of at least U.S. $30 billion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In order to continue to be included in the S&P GSCI<sup>®</sup>, a
contract that is already included in the S&P GSCI<sup>®</sup> at the time of determination and that is based on a commodity on
which there are one or more contracts already included in the S&P GSCI<sup>®</sup> at such time must have an annualized total
dollar value traded, over the relevant period of at least U.S. $10 billion over the relevant period and of at least U.S. $20 billion during
at least one of the three most recent annual periods used in making the determination.

In addition to the volume requirements described above, a contract must have a minimum reference percentage dollar weight:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In order to continue to be included in the S&P GSCI<sup>®</sup>, a
contract that is already included in the S&P GSCI<sup>®</sup> at the time of determination must have a reference percentage dollar
weight of at least 0.10%. The reference percentage dollar weight of a contract is determined by multiplying the CPW (defined
below) of a contract by the average of its daily contract reference prices on the last day of each month during the relevant period. These
amounts are summed for all contracts included in the S&P GSCI<sup>®</sup> and each contract's percentage of the total is
then determined.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In order to be added to the S&P GSCI<sup>®</sup>, a contract that
is not included in the S&P GSCI<sup>®</sup> at the time of determination must have a reference percentage dollar weight of at
least 1.00% at the time of determination.

In the event that two or more contracts on the same commodity satisfy the eligibility criteria, such contracts are included in the S&P GSCI<sup>®</sup> in the order of their respective total quantity traded during the relevant period (determined as the total quantity of the commodity underlying transactions in the relevant contract), with the contract having the highest total quantity traded being included first. No further contracts are included if such inclusion results in the portion of the S&P GSCI<sup>®</sup> attributable to such commodity exceeding a particular level.

If under the procedure set forth in the preceding paragraph, additional contracts could be included with respect to several commodities at the same time, the procedure is first applied to the commodity that has the smallest portion of the S&P GSCI<sup>®</sup> attributable to it at the time of determination. Subject to the other eligibility criteria, the contract with the highest total quantity traded on such commodity is included. Before any additional contracts on any commodity are included, the portion of the S&P GSCI<sup>®</sup> attributable to all commodities is recalculated. The

selection procedure described above is then repeated with respect to the contracts on the commodity that then has the smallest portion of the S&P GSCI<sup>®</sup> attributable to it.

The contracts currently included in the S&P GSCI<sup>®</sup> are all futures contracts traded on the New York Mercantile Exchange, Inc. ("NYMEX"), ICE Futures Europe ("ICE-Europe"), ICE Futures U.S. ("ICE-US"), the Chicago Mercantile Exchange ("CME"), the Chicago Board of Trade ("CBOT"), the Kansas City Board of Trade ("KBT"), the Commodities Exchange Inc. ("CMX") and the London Metal Exchange ("LME").

The quantity of each of the contracts included in the S&P GSCI<sup>®</sup> is determined on the basis of a five-year average (referred to as the "world production average") of the production quantity of the underlying commodity from sources determined by S&P Dow Jones to be reasonably accurate and reliable, such as the United Nations Industrial Commodity Statistics Yearbook. However, if a commodity is primarily a regional commodity, based on its production, use, pricing, transportation or other factors, S&P Dow Jones may calculate the weight of such commodity based on regional, rather than world, production data. At present, natural gas is the only commodity included in the S&P GSCI<sup>®</sup> where the production quantity is determined based on regional (North American) production.

The five-year moving average is updated annually for each commodity included in the S&P GSCI<sup>®</sup>, based on the five-year period (ending approximately two years prior to the date of calculation and moving backwards) for which complete data for all commodities is available. The contract production weights (the "CPWs") used in calculating the S&P GSCI<sup>®</sup> are derived from world or regional production averages, as applicable, of the relevant commodities, and are calculated based on the total quantity traded for the relevant contract and the world or regional production average, as applicable, of the underlying commodity. However, if the volume of trading in the relevant contract, as a multiple of the production levels of the commodity, is below specified thresholds, the CPW of the contract is reduced until the threshold is satisfied. This is designed to ensure that trading in each such contract is sufficiently liquid relative to the production of the commodity.

In addition, S&P Dow Jones performs this calculation on a quarterly basis and, if the multiple of any contract is below the prescribed threshold, the composition of the S&P GSCI<sup>®</sup> is reevaluated, based on the criteria and weighting procedure described above. This procedure is undertaken to allow the S&P GSCI<sup>®</sup> to shift from contracts that have lost substantial liquidity into more liquid contracts, during the course of a given year. As a result, it is possible that the composition or weighting of the S&P GSCI<sup>®</sup> will change on one or more of these quarterly evaluation dates. In addition, regardless of whether any changes have occurred during the year, S&P Dow Jones reevaluates the composition of the S&P GSCI<sup>®</sup> at the conclusion of each year, based on the above criteria. Other commodities that satisfy such criteria, if any, will be added to the S&P GSCI<sup>®</sup>. Commodities included in the S&P GSCI<sup>®</sup> that no longer satisfy such criteria, if any, will be deleted.

S&P Dow Jones also determines whether modifications in the selection criteria or the methodology for determining the composition and weights of and for calculating the S&P GSCI<sup>®</sup> are necessary or appropriate in order to assure that the S&P GSCI<sup>®</sup> represents a measure of commodity market performance. S&P Dow Jones has the discretion to make any such modifications.

**Contract Expirations** 

Because the S&P GSCI<sup>®</sup> comprises actively traded contracts with scheduled expirations, it can only be calculated by reference to the prices of contracts for specified expiration, delivery or settlement periods, referred to as "contract expirations." The contract expirations included in the S&P GSCI<sup>®</sup> for each commodity during a given year are designated by S&P Dow Jones, *provided* that each such contract must be an "active contract." An "active contract" for this purpose is a liquid, actively traded contract expiration, as defined or identified by the relevant trading facility or, if no such definition or identification is provided by the relevant trading facility, as defined by standard custom and practice in the industry.

If a trading facility deletes one or more contract expirations, the S&P GSCI<sup>®</sup> will be calculated during the remainder of the year in which such deletion occurs based on the remaining contract expirations designated by S&P Dow Jones. If a trading facility ceases trading in all contract expirations relating to a particular contract, S&P Dow Jones may designate an eligible replacement contract on the commodity. To the extent practicable, the replacement

will be in effect during the next monthly review of the composition of the S&P GSCI<sup>®</sup>. If that timing is not practicable, S&P Dow Jones will determine the date of the replacement and will consider a number of factors, including the differences between the existing contract and the replacement contract specifications and contract expirations.

**Value of the S&P GSCI<sup>®</sup>**

The value of the S&P GSCI<sup>®</sup> on any given day is equal to the total dollar weight of the S&P GSCI<sup>®</sup> divided by a normalizing constant that assures the continuity of the S&P GSCI<sup>®</sup> over time. The total dollar weight of the S&P GSCI<sup>®</sup> is the sum of the dollar weight of each of the underlying commodities.

The dollar weight of each such commodity on any given day is equal to:

&nbsp;&nbsp;&nbsp;&nbsp;· the "daily contract reference price" (discussed below),

&nbsp;&nbsp;&nbsp;&nbsp;· multiplied by the appropriate CPWs, and

&nbsp;&nbsp;&nbsp;&nbsp;· during a roll period, the appropriate "roll weights" (discussed
below).

The daily contract reference price used in calculating the dollar weight of each commodity on any given day is the most recent daily contract reference price made available by the relevant trading facility, except that the daily contract reference price for the most recent prior day will be used if the exchange is closed or otherwise fails to publish a daily contract reference price on that day. In addition, if the trading facility fails to make a daily contract reference price available or publishes a daily contract reference price that, in the reasonable judgment of S&P Dow Jones, reflects manifest error, the relevant calculation will be delayed until the price is made available or corrected; *provided* that, if the price is not made available or corrected by 4:00 p.m., New York City time, S&P Dow Jones may, if it deems such action to be appropriate under the circumstances, determine the appropriate daily contract reference price for the applicable futures contract in its reasonable judgment for purposes of the relevant S&P GSCI<sup>®</sup> calculation.

The "roll weight" of each commodity reflects the fact that the positions in contracts must be liquidated or rolled forward into more distant contract expirations as they approach expiration. If actual positions in the relevant markets were rolled forward, the roll would likely need to take place over a period of days. Since the S&P GSCI<sup>®</sup> is designed to replicate the performance of actual investments in the underlying contracts, the rolling process incorporated in the S&P GSCI<sup>®</sup> also takes place over a period of days at the beginning of each month (referred to as the "roll period"). On each day of the roll period, the "roll weights" of the first nearby contract expiration on a particular commodity and the more distant contract expiration into which it is rolled are adjusted, so that the hypothetical position in the contract on the commodity that is included in the S&P GSCI<sup>®</sup> is gradually shifted from the first nearby contract expiration to the more distant contract expiration.

If on any day during a roll period any of the following conditions exists, the portion of the roll that would have taken place on that day is deferred until the next day on which such conditions do not exist:

&nbsp;&nbsp;&nbsp;&nbsp;· no daily contract reference price is available for a given contract expiration;

&nbsp;&nbsp;&nbsp;&nbsp;· any such price represents the maximum or minimum price for such contract
month, based on exchange price limits (referred to as a "Limit Price");

&nbsp;&nbsp;&nbsp;&nbsp;· the daily contract reference price published by the relevant trading facility
reflects manifest error, or such price is not published by 4:00 p.m., New York City time. In that event, S&P Dow Jones
may, but is not required to, determine a daily contract reference price and complete the relevant portion of the roll based on such price; *provided* that, if the trading facility publishes a price before the opening of trading on the next day, S&P Dow Jones will
revise the portion of the roll accordingly; or

&nbsp;&nbsp;&nbsp;&nbsp;· trading in the relevant contract terminates prior to its scheduled closing
time.

If any of these conditions exist throughout the roll period, the roll with respect to the affected contract will be effected in its entirety on the next day on which such conditions no longer exist.

**Contract Daily Return** 

The contract daily return on any given day is equal to the sum, for each of the commodities included in the S&P GSCI<sup>®</sup>, of the applicable daily contract reference price on the relevant contract multiplied by the appropriate CPW and the appropriate "roll weight," divided by the total dollar weight of the S&P GSCI<sup>®</sup> on the preceding day, minus one.

**Calculation of the S&P GSCI<sup>®</sup> Indices** 

*Excess return S&P GSCI<sup>®</sup> Indices*

The value of any excess return version of a S&P GSCI<sup>®</sup> Index on any day on which the S&P GSCI<sup>®</sup> is calculated (an "S&P GSCI<sup>®</sup> Business Day") is equal to the product of:

&nbsp;&nbsp;&nbsp;&nbsp;· the value of the applicable S&P GSCI<sup>®</sup> Index on the immediately
preceding S&P GSCI<sup>®</sup> Business Day; and

&nbsp;&nbsp;&nbsp;&nbsp;· one *plus* the contract daily return of the applicable S&P GSCI<sup>®</sup>
Index on the S&P GSCI<sup>®</sup> Business Day on which the calculation is made.

*Total Return S&P GSCI<sup>®</sup> Indices*

The value of any total return version of an S&P GSCI<sup>®</sup> Index on any S&P GSCI<sup>®</sup> Business Day reflects the value of an investment in the excess return version of that S&P GSCI<sup>®</sup> Index together with a Treasury bill return and is equal to the product of:

&nbsp;&nbsp;&nbsp;&nbsp;· the value of the applicable S&P GSCI<sup>®</sup> Index on the immediately
preceding S&P GSCI<sup>®</sup> Business Day;

&nbsp;&nbsp;&nbsp;&nbsp;· one *plus* the sum of the contract daily return and the Treasury Bill
return on the S&P GSCI<sup>®</sup> Business Day on which the calculation is made; and

&nbsp;&nbsp;&nbsp;&nbsp;· one *plus* the Treasury Bill return for each non-S&P GSCI<sup>®</sup>
Business Day since the immediately preceding S&P GSCI<sup>®</sup> Business Day.

The Treasury Bill return is the return on a hypothetical investment in the applicable S&P GSCI<sup>®</sup> Index at a rate equal to the interest rate on a specified U.S. Treasury Bill.

**Index Governance**

*Index Committee* 

S&P Dow Jones has established an index committee with respect to the S&P GSCI<sup>®</sup> Indices (the "Index Committee") to oversee the daily management and operations of the S&P GSCI<sup>®</sup>, and is responsible for all analytical methods and calculation of the S&P GSCI<sup>®</sup> Indices. The Index Committee consists of full-time professional members of S&P Dow Jones's staff. At each meeting, the Index Committee reviews any issues that may affect index constituents, statistics comparing the composition of the indices to the market, commodities that are being considered as candidates for addition to an index and any significant market events. In addition, the Index Committee may revise index policy covering rules for selecting commodities or other matters.

S&P Dow Jones considers information about changes to the S&P GSCI<sup>®</sup> Indices and related matters to be potentially market-moving and material. Therefore, all Index Committee discussions are confidential.

The Index Committee reserves the right to make exceptions when applying the methodology of the S&P GSCI<sup>®</sup> if the need arises.

In addition to the daily governance of the S&P GSCI<sup>®</sup> Indices and maintenance of their methodologies, at least once within any 12-month period, the Index Committee reviews the methodology to ensure the S&P GSCI<sup>®</sup> Indices continue to achieve the stated objectives, and that the data and methodology remain effective. In certain instances, S&P Dow Jones may publish a consultation inviting comments from external parties.

**The Commodity Futures Markets**

Futures contracts on physical commodities are traded on regulated futures exchanges, in the over-the-counter market and on various types of physical and electronic trading facilities and markets. As of the date of this underlying supplement, all of the contracts included in the S&P GSCI<sup>®</sup> Indices are exchange-traded futures contracts. An exchange-traded futures contract provides for the purchase and sale of a specified type and quantity of a commodity or financial instrument during a stated delivery month for a fixed price. A futures contract provides for a specified settlement month in which cash settlement is made or in which the commodity or financial instrument is to be delivered by the seller (whose position is therefore described as "short") and acquired by the purchaser (whose position is therefore described as "long").

No purchase price is paid or received on the purchase or sale of a futures contract. Instead, an amount of cash or cash equivalents must be deposited with the broker as "initial margin." This amount varies based on the requirements imposed by the exchange clearinghouses, but it may be lower than 5% of the notional value of the contract. This margin deposit provides collateral for the obligations of the parties to the futures contract.

By depositing margin, which may vary in form depending on the exchange, with the clearinghouse or broker involved, a market participant may be able to earn interest on its margin funds, thereby increasing the total return that it may realize from an investment in futures contracts.

Futures contracts are traded on organized exchanges, known as "contract markets" in the United States. At any time prior to the expiration of a futures contract, a trader may elect to close out its position by taking an opposite position on the exchange on which the trader obtained the position, subject to the availability of a liquid secondary market. This operates to terminate the position and fix the trader's profit or loss. Futures contracts are cleared through the facilities of a centralized clearinghouse and a brokerage firm, referred to as a "futures commission merchant," which is a member of the clearinghouse.

Unlike equity securities, futures contracts, by their terms, have stated expirations at a specified point in time prior to expiration. At a specific point in time prior to expiration, trading in a futures contract for the current delivery month will cease. As a result, a market participant wishing to maintain its exposure to a futures contract on a particular commodity or financial instrument with the nearest expiration must close out its position in the expiring contract and establish a new position in the contract for the next delivery month, a process referred to as "rolling." For example, a market participant with a long position in a futures contract expiring in November who wishes to maintain a position in the nearest delivery month will, as the November contract nears expiration, sell the November contract, which serves to close out the existing long position, and buy a futures contract expiring in December. This will "roll" the November position into a December position, and, when the November contract expires, the market participant will still have a long position in the nearest delivery month.

Futures exchanges and clearinghouses in the United States are subject to regulation by the Commodity Futures Trading Commission. Exchanges may adopt rules and take other actions that affect trading, including imposing speculative position limits, maximum price fluctuations and trading halts and suspensions and requiring liquidation of contracts in certain circumstances.

Futures markets outside the United States are generally subject to regulation by comparable regulatory authorities. The structure and nature of trading on non-U.S. exchanges may differ from this description. From their inception to the present, the S&P GSCI<sup>®</sup> Indices have been composed exclusively of futures contracts traded on regulated exchanges.

**Fund Descriptions**

**The Invesco QQQ Trust**<sup>℠</sup>, Series 1**

All information contained in this underlying supplement regarding the Invesco QQQ Trust<sup>℠</sup>, Series 1 (the "**QQQ Fund**") has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, The Bank of New York Mellon, as trustee of the QQQ Fund (the "**QQQ Fund Trustee**"), and Invesco Capital Management LLC, as sponsor of the QQQ Fund. The QQQ Fund is a unit investment trust that issues securities called "Invesco QQQ Shares." The QQQ Fund trades on The Nasdaq Stock Market under the ticker symbol "QQQ."

The investment objective of the QQQ Fund is to seek to track the investment results, before fees and expenses, of the Nasdaq-100 Index<sup>®</sup>. The Nasdaq-100 Index<sup>®</sup> is a modified market capitalization-weighted index that is designed to measure the performance of 100 of the largest non-financial companies listed on The Nasdaq Stock Market. For more information about the Nasdaq-100 Index<sup>®</sup>, please see "Equity Index Descriptions—The Nasdaq-100 Index<sup>®</sup>."

The QQQ Fund holds all of the stocks in the Nasdaq-100 Index<sup>®</sup> and cash and is not actively managed by traditional methods, which typically involve effecting changes in the holdings of securities on the basis of judgments made relating to economic, financial and market considerations. To maintain the correspondence between the composition and weights of the securities held by the QQQ Fund and the component securities of the Nasdaq-100 Index<sup>®</sup> ("**QQQ Index Securities**"), the QQQ Fund Trustee adjusts the holdings of the QQQ Fund from time to time to conform to periodic changes in the identity and/or relative weights of the QQQ Index Securities.

The QQQ Fund will not be able to replicate exactly the performance of the Nasdaq-100 Index<sup>®</sup> because the total return generated by the securities held by the QQQ Fund will be reduced by transaction costs incurred in adjusting the actual balance of the securities held by the QQQ Fund and other expenses of the QQQ Fund, whereas such transaction costs and expenses are not included in the calculation of the Nasdaq-100 Index<sup>®</sup>. It is also possible that for short periods of time, the QQQ Fund may not fully replicate the performance of the Nasdaq-100 Index<sup>®</sup> due to the temporary unavailability of certain QQQ Index Securities in the secondary market or due to other extraordinary circumstances. Such events are unlikely to continue for an extended period of time because the QQQ Fund Trustee is required to correct such imbalances by means of adjusting the composition of the securities held by the QQQ Fund. It is also possible that the composition of the QQQ Fund may not exactly replicate the composition of the Nasdaq-100 Index<sup>®</sup> if the QQQ Fund has to adjust its portfolio holdings in order to continue to qualify as a "regulated investment company" under the Internal Revenue Code of 1986, as amended.

The QQQ Fund is a registered investment company. Information provided to or filed with the SEC by the QQQ Fund pursuant to the Securities Act of 1933, as amended, and the Investment Company Act of 1940, as amended, can be located by reference to SEC file numbers 333-61001 and 811-08947, respectively, through the SEC's website at http://www.sec.gov.

**The iShares<sup>®</sup> 20+ Year Treasury Bond ETF**

All information contained in this underlying supplement regarding the iShares<sup>®</sup> 20+ Year Treasury Bond ETF has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, iShares<sup>®</sup> Trust and BlackRock Fund Advisors ("**BFA**"). The iShares<sup>®</sup> 20+ Year Treasury Bond ETF is an investment portfolio of iShares<sup>®</sup> Trust and is maintained and managed by BFA. BFA is currently the investment advisor to the iShares<sup>®</sup> 20+ Year Treasury Bond ETF. The iShares<sup>®</sup> 20+ Year Treasury Bond ETF is an exchange-traded fund that trades on The Nasdaq Stock Market under the ticker symbol "TLT."

The iShares<sup>®</sup> 20+ Year Treasury Bond ETF seeks to track the investment results, before fees and expenses, of an index composed of U.S. Treasury bonds with remaining maturities greater than twenty years, which is currently the ICE U.S. Treasury 20+ Year Bond Index. For more information about the ICE U.S. Treasury 20+ Year Bond Index, please see "—The ICE U.S. Treasury 20+ Year Bond Index" below.

BFA uses a representative sampling indexing strategy to manage the iShares<sup>®</sup> 20+ Year Treasury Bond ETF. "Representative sampling" is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to that of an applicable underlying index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and industry weightings), fundamental characteristics (such as return variability, duration, maturity or credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The iShares<sup>®</sup> 20+ Year Treasury Bond ETF may or may not hold all of the securities in the ICE U.S. Treasury 20+ Year Bond Index.

The iShares<sup>®</sup> 20+ Year Treasury Bond ETF is subject to "tracking error," which is the divergence of the performance of the iShares<sup>®</sup> 20+ Year Treasury Bond ETF's portfolio from that of the ICE U.S. Treasury 20+ Year Bond Index. Tracking error may occur because of differences between the securities held in the iShares<sup>®</sup> 20+ Year Treasury Bond ETF's portfolio and those included in the ICE U.S. Treasury 20+ Year Bond Index, pricing differences, transaction costs incurred by the iShares<sup>®</sup> 20+ Year Treasury Bond ETF, the iShares<sup>®</sup> 20+ Year Treasury Bond ETF's holding uninvested cash, differences in the timing of accrual or the valuation of distributions, requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains, acceptance of custom baskets, changes to the ICE U.S. Treasury 20+ Year Bond Index and costs to the iShares<sup>®</sup> 20+ Year Treasury Bond ETF of complying with new or existing regulatory requirements, among other reasons. Because the iShares<sup>®</sup> 20+ Year Treasury Bond ETF uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. "Replication" is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

iShares<sup>®</sup> Trust is a registered investment company that consists of numerous separate investment portfolios, including the iShares<sup>®</sup> 20+ Year Treasury Bond ETF. Information provided to or filed with the SEC by iShares<sup>®</sup> Trust pursuant to the Securities Act of 1933, as amended, and the Investment Company Act of 1940, as amended, can be located by reference to SEC file numbers 333-92935 and 811-09729, respectively, through the SEC's website at http://www.sec.gov.

**The ICE U.S. Treasury 20+ Year Bond Index**

All information contained in this underlying supplement regarding the ICE U.S. Treasury 20+ Year Bond Index is derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, ICE Data Indices, LLC or its affiliates (collectively "**IDI**"), a subsidiary of Intercontinental Exchange, Inc. IDI has no obligation to continue to publish, and may discontinue publication of, the ICE U.S. Treasury 20+ Year Bond Index.

The ICE U.S. Treasury 20+ Year Bond Index is a market value-weighted index that is designed to measure the performance of U.S. dollar-denominated, fixed-rate U.S. Treasury securities with a remaining maturity of greater than 20 years. The ICE U.S. Treasury 20+ Year Bond Index was launched on December 31, 2015. The ICE U.S. Treasury 20+ Year Bond Index is reported by Bloomberg L.P. under the ticker symbol "IDCOT20."

***Index Eligibility Criteria and Inclusion Rules***

The ICE U.S. Treasury 20+ Year Bond Index consists of securities that meet the criteria listed below (the "**Eligible Bond universe**"). The basis of the Eligible Bond universe are those securities for which content is available daily, including evaluations and reference data, through ICE Data Pricing & Reference Data, LLC ("**PRD**").

*Maturity.* Each security must have greater than twenty years remaining term to final maturity as of the rebalancing date.

*Size.* Each security is required to have a minimum amount outstanding of U.S. $300 million, excluding amounts held by the Federal Reserve System Open Market Account ("**SOMA**"). Amounts outstanding of qualifying coupon securities are not reduced by any portions that have been stripped.

*Coupon.* The Eligible Bond universe includes only fixed-rate securities, excluding zero coupon Separate Trading of Registered Interest and Principal of Securities ("**STRIPS**").

*Currency.* The Eligible Bond universe includes only securities with principal and interest denominated in U.S. dollars.

*Bond Type.* The Eligible Bond universe includes sovereign debt publicly issued by the U.S. government in its domestic market, excluding the following: inflation-linked securities, U.S. Treasury bills, original issue zero coupon securities, STRIPs, any government agency debt issued with or without a U.S. government guarantee and securities issued or marketed primarily to retail investors.

***Index Maintenance***

The ICE U.S. Treasury 20+ Year Bond Index is rebalanced monthly. Securities are required to meet the inclusion rules highlighted in the previous section to be considered for inclusion at the beginning of any given month. This includes the availability of evaluated pricing and reference data through PRD.

*Rebalancing.* The ICE U.S. Treasury 20+ Year Bond Index is rebalanced on the last calendar day of the month based on information available up to and including the third business day before the last business day of the month. No changes are made to constituents holdings other than on month end rebalancing dates.

*Reinvestment of Cash Flows.* Cash that has accrued intra-month from interest and principal payments by the securities included in the ICE U.S. Treasury 20+ Year Bond Index earns no reinvestment return during the month. Accumulated cash (from coupon and principal payments) is retained in the ICE U.S. Treasury 20+ Year Bond Index until month-end and then removed as part of rebalancing, such that the cash is reinvested pro rata across the ICE U.S. Treasury 20+ Year Bond Index.

*New Issues.* New issues must be auctioned on or before the calendar month end rebalancing date in order to qualify for inclusion in the coming month.

***Index Policies***

*Timing and Pricing Source.* The ICE U.S. Treasury 20+ Year Bond Index's level is calculated using 4:00 p.m. Eastern Standard Time using bid-side evaluations from PRD. These evaluations are based upon methodologies designed to reflect the market upon which the ICE U.S. Treasury 20+ Year Bond Index is based.

*Calendar.* The ICE U.S. Treasury 20+ Year Bond Index follows the SIFMA U.S. bond market holiday schedule. The ICE U.S. Treasury 20+ Year Bond Index's level is calculated daily at the end of each day on which SIFMA declares the U.S. fixed income markets open. When the bond market closes early per the SIFMA schedule, the ICE U.S. Treasury 20+ Year Bond Index's level may be calculated at a time in accordance with the recommended close. However, evaluated pricing from PRD must be available to calculate the ICE U.S. Treasury 20+ Year Bond Index's level.

*Exceptional Market Conditions and Corrections.* IDI retains the right to delay the publication of the level of the ICE U.S. Treasury 20+ Year Bond Index. Furthermore, IDI retains the right to suspend the publication of the level of the ICE U.S. Treasury 20+ Year Bond Index if it believes that circumstances prevent the proper calculation of the ICE U.S. Treasury 20+ Year Bond Index. If evaluated prices are not available, the ICE U.S. Treasury 20+ Year Bond Index will not be recalculated unless IDI decides otherwise. Reasonable efforts are made to ensure the correctness and validity of data used in index calculations. Where errors have occurred in the determination or calculation of the ICE U.S. Treasury 20+ Year Bond Index, the decision to make a restatement will be assessed on a case by case basis. Such decision will take account of the significance, impact; age; and scale of the error. Errors involving security reference data discovered after the rebalancing will typically not result in a restatement.

In the event that there is a market-wide event resulting in evaluated prices not being available, IDI will determine its approach on a case by case basis, taking into account information and notifications provided by PRD. Market-wide events include, but are not limited to, technological problems or failures, natural disaster or other business continuity planning-related event. IDI will communicate any issues with publication of the ICE U.S. Treasury 20+ Year Bond Index during the day through the regular client communication channels; in addition, IDI may also contact clients directly; post a notice on the IDI website; send a message via the market data portal; or use other such forms of communication.

*Annual Rules Review.* Potential rule changes are considered on an annual basis. An initial set of proposed changes under consideration is generally published in April. Investor clients are encouraged to comment on the proposals by way of an online survey. At the end of a commentary period, final decisions are announced, generally in July, and adopted changes, if any, are generally implemented at the September month-end rebalancing. IDI, at its sole discretion, reserves the right to issue rule changes apart from this annual cycle.

*Expert Judgment.* "Expert Judgment" refers to the exercise of discretion by IDI with respect to the use of data in determining the ICE U.S. Treasury 20+ Year Bond Index. Expert Judgment includes extrapolating values from prior or related transactions, adjusting values for factors that might influence the quality of data such as market events or impairment of a buyer or seller's credit quality, or weighting firm bids or offers greater than a particular concluded transaction.

While IDI mostly relies on input data obtained from its sources, on certain occasions, where decisions relating to the pricing of the ICE U.S. Treasury 20+ Year Bond Index are required to maintain the integrity of the values and ensure that the ICE U.S. Treasury 20+ Year Bond Index continues to operate in line with the methodology, IDI may apply Expert Judgment. Where it is required in the determination of the ICE U.S. Treasury 20+ Year Bond Index, it may only be applied by suitably experienced and qualified staff members on the IDI team. Using their expertise and knowledge, and the information available to them, they will make an assessment of what input data or security evaluation would be most appropriate to use to correctly reflect the ICE U.S. Treasury 20+ Year Bond Index objective.

Ultimately any exercise of Expert Judgment is overseen by the governance committee of IDI, which ensures that the published methodologies have been followed.

**The iShares<sup>®</sup> ETFs**

All information contained in this underlying supplement regarding the iShares<sup>®</sup> Biotechnology ETF, the iShares<sup>®</sup> MSCI Brazil ETF, the iShares<sup>®</sup> MSCI EAFE<sup>®</sup> ETF, the iShares<sup>®</sup> MSCI Emerging Markets ETF, the iShares<sup>®</sup> MSCI Japan ETF, the iShares<sup>®</sup> MSCI Mexico ETF, the iShares<sup>®</sup> Russell 2000 ETF, the iShares<sup>®</sup> Russell 3000 ETF and the iShares<sup>®</sup> U.S. Real Estate ETF (each, an "**iShares ETF**" and collectively, the "**iShares ETFs**") has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, the fund manager of each iShares ETF and BlackRock Fund Advisors ("**BFA**"). The iShares ETFs are investment portfolios of either iShares Trust<sup>®</sup> or iShares<sup>®</sup>, Inc. and are maintained and managed by their respective fund managers. BFA is currently the investment advisor to the iShares ETFs.

BFA uses a representative sampling indexing strategy to manage each iShares ETF. "Representative sampling" is an indexing strategy that involves investing in a representative sample of securities or other instruments that collectively has an investment profile similar to that of an applicable underlying index. The instruments selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of an applicable underlying index. An iShares ETF may or may not hold all of the securities in its underlying index.

Each iShares ETF's underlying index is a financial calculation, based on a grouping of financial instruments, and is not an investment product, while each iShares ETF is an actual investment portfolio. The performance of each iShares ETF and its underlying index may vary for a number of reasons, including transaction costs, asset or currency valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between that iShares ETF's portfolio and its underlying index resulting from that iShares ETF's use of representative sampling or from legal restrictions (such as diversification requirements) that apply to that iShares ETF but not to its underlying index. "Tracking error" is the divergence of the performance (return) of an iShares ETF's portfolio from that of its underlying index. Because each iShares ETF uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. "Replication" is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

***The NYSE Biotechnology Index<sup>®</sup>***

All information contained in this underlying supplement regarding the NYSE Biotechnology 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 ICE Data Indices, LLC ("**IDI**"). The NYSE Biotechnology Index is calculated, maintained and published by IDI. IDI has no obligation to continue to publish, and may discontinue publication of, the NYSE Biotechnology Index.

The NYSE Biotechnology Index is reported by Bloomberg L.P. under the ticker symbol "NYBIO."

The NYSE Biotechnology Index is a modified float-adjusted market capitalization-weighted index that is designed to track the performance of qualifying U.S.-listed biotechnology companies. IDI defines biotechnology companies as those classified within the biotechnology sub-industry group of the ICE Uniform Sector Classification schema, which is a multi-asset class industry classification taxonomy developed by ICE. This includes companies that are engaged in the research and development of therapeutic treatments but are not focused on the commercialization and mass production of pharmaceutical drugs. This also includes companies that are engaged in the production of tools or systems that enable biotechnology processes.

*NYSE Biotechnology Index Constituent Selection*

The NYSE Biotechnology Index includes common stocks, ordinary shares, American depositary receipts ("**ADRs**"), shares of beneficial interest and limited partnership interest that meet the following criteria:

respective float-adjusted security-level market capitalization weighting.

*NYSE Biotechnology Index Construction* 

The NYSE Biotechnology Index is subject to the following exposure limits:

&nbsp;&nbsp;&nbsp;&nbsp;(1) All constituents are capped at 8% with any excess weight redistributed on a pro-rata basis to constituents below that cap, provided
none can be increased above 8%.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The weights of constituents outside the initial five largest are capped at 4% with any excess weight redistributed on a pro-rata basis
to (i) any of the five largest constituents that are below 8% (provided they cannot be increased above 8%), and (ii) any other constituents
that are below 4% (provided none are increased above 4%).

&nbsp;&nbsp;&nbsp;&nbsp;(3) The cumulative weight of all ADRs is capped at 10% with the reductions applied proportionately across that group. Excess
weight is redistributed on a pro-rata basis to (i) any non-ADR constituents among the resulting five largest constituents that are below
8% (provided they cannot be increased above 8%) and (ii) any other non-ADR constituents that are below 4% (provided they cannot be increased
above 4%).

*NYSE Biotechnology Index Calculation*

The NYSE Biotechnology Index level is calculated by dividing the current index market capitalization by the index divisor. The index market capitalization represents the sum product of index constituent shares and prices. The divisor is determined as a function of the initial index market capitalization and base index level. The divisor is updated as a result of corporate actions, reconstitutions, rebalances and any other composition changes.

Free float levels are calculated by dividing the security free float shares by the total security shares outstanding. The security free float shares are equal to the security shares outstanding minus treasury shares and strategic holdings by other corporations, holding companies, individuals, and government agencies. Individual holdings are deemed strategic if the individual, or a member of the individual's immediate family, is an officer or director of the company, or if they comprise a significant percentage of total shares outstanding (commonly 5% or more). Shares held by banks and financial institutions in a fiduciary capacity are not deemed strategic.

*NYSE Biotechnology Index Maintenance and Adjustments*

The NYSE Biotechnology Index undergoes a full reconstitution of constituent holdings annually after the close of the third Friday of December. At the annual reconstitution, qualifying constituents are re-selected based on the above criteria, and float-adjusted market capitalization weights are determined subject to the above exposure limits. The reference date for the input data used to determine security qualification is the close of the last trading day of October, and reference data for the input data used to determine weights is the close of the last trading day of November. The announcement date is the close of the first Friday of December.

In addition to the annual reconstitution, the NYSE Biotechnology Index undergoes a rebalancing after the close of the third Friday of March, June, and September. At the quarterly rebalancings, no constituents are added to or removed from the NYSE Biotechnology Index; however, constituent weights are recalculated based on updated float-adjusted market capitalizations subject to the issuer and ADR exposure limits. The reference date for all input data used in the quarterly rebalances is the close of the last trading day of the month preceding the month of effectiveness (February, May, August) and the announcement date is the close of the first Friday of the rebalance month.

The NYSE Biotechnology Index is adjusted for corporate actions that affect constituents and implements any intra-quarter float-adjusted shares outstanding updates greater than 10% in scheduled monthly share updates that take effect after the close of the last trading day of each month. Securities are removed from the NYSE Biotechnology Index only when both the transaction and delisting is either confirmed or deemed imminent. If a security is suspended prior to its removal from the NYSE Biotechnology Index, then the security is deleted at the close of the next trading day at either the last traded price (cash only terms) or the value of the deal terms (share or cash/share terms), if available. There are no intra-quarter replacements of constituents in the NYSE Biotechnology Index. The NYSE Biotechnology Index implements a zero-price spin-off policy. A spin-co is added into the NYSE Biotechnology Index effective for the spin-off ex-date with a $0 price and no price adjustment is made on the parent constituent. After the close of the first day of trading for the spin-co, it is deleted from the NYSE Biotechnology Index at its last traded price.

***The Dow Jones U.S. Real Estate Capped Index***

All information contained in this underlying supplement regarding the Dow Jones U.S. Real Estate Capped 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**"). The Dow Jones U.S. Real Estate Capped Index is calculated, maintained and published by S&P Dow Jones. S&P Dow Jones has no obligation to continue to publish, and may discontinue the publication of, the Dow Jones U.S. Real Estate Capped Index.

The Dow Jones U.S. Real Estate Capped Index is a modified market capitalization-weighted index that is designed to track the performance of real estate investment trusts ("**REITs**") and other companies that invest directly or indirectly in real estate through development, management or ownership, including property agencies, with a cap applied to ensure diversification among constituents. The Dow Jones U.S. Real Estate Capped Index is reported by Bloomberg L.P. under the ticker symbol "DJUSRCUP."

Index composition of the Dow Jones U.S. Real Estate Capped Index is the same as the underlying sector index, which is the Dow Jones U.S. Real Estate Index. Constituent changes are incorporated in the Dow Jones U.S. Real Estate Capped Index as and when they are made in the Dow Jones U.S. Real Estate Index. Any addition not coinciding with a reweighting effective date, except for spin-offs, will be added to the Dow Jones U.S. Real Estate Capped Index with the largest additional weight factor currently represented in the Dow Jones U.S. Real Estate Capped Index.

For capping purposes, the Dow Jones U.S. Real Estate Capped Index is rebalanced quarterly after the close of business on the third Friday of March, June, September and December. The reference date for capping is the Wednesday before the second Friday of the rebalancing month. The Dow Jones U.S. Real Estate Capped Index is also reviewed daily based on each company's capped market capitalization weight. Daily capping is only performed when the sum of companies with a weight greater than 5% exceeds 25%. When daily capping is necessary, the changes are announced after the close of business on the day in which the daily weight cap is exceeded, with the reference date after the close of that same business day. Changes are effective after the close of the next trading day. While capping is reviewed daily, the Dow Jones U.S. Real Estate Capped Index may be capped on a less frequent basis. Both the quarterly capping process and the daily capping process are performed according to the following procedures:

&nbsp;&nbsp;&nbsp;&nbsp;1. With prices reflected on the rebalancing price reference date, adjusted for any applicable corporate actions, and membership, shares
outstanding and investable weight factors ()"**IWFs**") as of the rebalancing effective date, each company is weighted by
float-adjusted market capitalization ()"**FMC** "). Modifications are made as defined below.

&nbsp;&nbsp;&nbsp;&nbsp;2. If any company's weight exceeds the weight cap of 10%, that company's weight is capped at 10% and all excess weight is
proportionally redistributed to all uncapped companies within the index. If after this redistribution any company breaches the weight
cap, the process is repeated iteratively until no company breaches the company capping rule.

&nbsp;&nbsp;&nbsp;&nbsp;3. Then, the aggregate weight of the companies with a weight greater than 4.5% cannot exceed the aggregate cap of 22.5%.

&nbsp;&nbsp;&nbsp;&nbsp;4. If the rule in step 3 is breached, all the companies are ranked in descending order of their weights and the company with the smallest
weight above 4.5% is identified. The weight of this company is, then, reduced either until the rule in step 3 is satisfied or it reaches
4.5%.

&nbsp;&nbsp;&nbsp;&nbsp;5. This excess weight is proportionally redistributed to all companies with weights below 4.5%. Any company that receives weight cannot
breach the 4.5% cap. This process is repeated iteratively until step 3 is satisfied.

&nbsp;&nbsp;&nbsp;&nbsp;6. Index share amounts are assigned to each constituent to arrive at the weights calculated above. Since index shares are assigned based
on prices prior to rebalancing, the actual weight of each constituent at the rebalancing differs somewhat from these weights due to market
movements.

*Dow Jones U.S. Real Estate Index Composition and Maintenance*

The Dow Jones U.S. Real Estate Index is designed to track the performance of REITs and other companies that invest directly or indirectly in real estate through development, management, or ownership, including property agencies. REITs are passive investment vehicles that invest primarily in income producing real estate or real estate-related loans and interests.

The Dow Jones U.S. Real Estate Index is one of the supersector indices that make up the Dow Jones U.S. Index. The Dow Jones U.S. Real Estate Index is a subset of the Dow Jones U.S. Index, which is designed to be a measure

of the U.S. stock market, covering 95% of U.S. stocks by FMC, excluding the most thinly traded securities. The Dow Jones U.S. Real Estate Index is weighted by FMC, rather than full market capitalization, to reflect the actual number of shares available to investors.

The index universe is defined as all stocks traded on the major U.S. stock exchanges, minus any non-common issues and illiquid stocks. Index component candidates are filtered through screens for share class and eligibility. For share class, index component candidates must be common shares or other securities that have the characteristics of common equities. All classes of common shares, both fully and partially paid, are eligible. Temporary issues arising from corporate actions, such as "**when-issued shares**," are considered on a case-by-case basis when necessary to maintain continuity in a company's index membership. REITs, listed property trusts and similar real-property-owning pass-through structures taxed as REITs by their domiciles are also eligible. In some cases, companies issue multiple share classes. All publicly listed multiple share class lines are eligible for index inclusion. A separate IWF, which is an adjustment factor that accounts for publicly available shares of a company, is calculated for each included share class. For liquidity, each stock must meet two separate liquidity criteria to be considered eligible for inclusion:

&nbsp;&nbsp;&nbsp;&nbsp;· 12-Month Median Value Traded Ratio (MVTR). Stocks must have a MVTR of at least
20%. Current constituents remain eligible if they have a MVTR of at least 14%. This ratio is calculated by taking the median daily value
traded amount for each of the 12 months preceding the rebalancing reference date, multiplying the amount by the number of days that the
stock traded during that month, and then dividing by its end-of-month FMC. The sum of the 12 monthly values is the MVTR for that stock.
If a stock has traded for less than 12 months, the average of the available monthly values is taken and multiplied by 12.

&nbsp;&nbsp;&nbsp;&nbsp;· 6-Month Median Daily Value Traded (MDVT). Stocks must have a MDVT over the
six months prior to the rebalancing reference date of at least US$250,000. Current constituents remain eligible if they have a MDVT of
at least US$175,000. If a stock has traded for less than six months, the MDVT amount for as long as the stock has been trading is used.

Stocks in the index universe are sorted by FMC. Stocks in the top 95% of the index universe by FMC are selected as constituents of the Dow Jones U.S. Index. Selection is subject to a 2% buffer for current and non-current stocks. Current constituents remain eligible up to the 97th percentile as ranked by FMC. Non- constituents are eligible up to the 93rd percentile as ranked by FMC. The capitalization thresholds are calculated once a year during the annual reconstitution and used for screening potential additions during the quarterly rebalancings.

Stocks selected as components of the Dow Jones U.S. Index are then categorized into subsectors based on their primary source of revenue. The subsectors are rolled up into sectors, which in turn are rolled up into supersectors and finally into industries. Subsectors, sectors, supersectors and industries are defined by a proprietary classification system used by S&P Dow Jones. The Dow Jones U.S. Real Estate Index is a supersector that is a subset of the Dow Jones U.S. Index. Constituents of the Dow Jones U.S. Index that have an industry belonging to the real estate supersector will be added to the Dow Jones U.S. Real Estate Index on the effective date of the industry change. If a stock changes to a different supersector, the stock will be dropped on the effective date of the industry change.

The Dow Jones U.S. Real Estate Index is calculated by means of the divisor methodology. On any given day, the index value is the quotient of the total FMC of the Dow Jones U.S. Real Estate Index's constituents and its divisor. The key to index maintenance is the adjustment of the divisor. Index maintenance – reflecting changes in shares outstanding, corporate actions, addition or deletion of stocks to the index – should not change the level of the index. This is accomplished with an adjustment to the divisor. Any change to the stocks in the index that alters the total market value of the index while holding stock prices constant will require a divisor adjustment.

The Dow Jones U.S. Real Estate Index is reconstituted annually in September. The process includes the review of all stocks in their respective markets to determine eligibility according to the existing criteria. The reference date for data used in the annual reconstitution is the last business day in July. In addition, the IWF for each stock is reviewed and updated as needed. Changes are implemented at the opening of trading on the Monday following the third Friday of September. Changes to shares and IWFs are implemented at the open of trading on the Monday following the third Friday of March, June and December.

*Additions.* Except for quarterly additions, initial public offerings ("**IPOs**") and spin-offs, there are no additions between rebalancings. Any stocks considered for addition at a quarterly rebalancing must have an FMC larger than that of the smallest stock included in the Dow Jones U.S. Real Estate Index at the time of the previous reconstitution.

*Quarterly Additions.* IPOs as well as new listings on eligible exchanges and issues that emerged from bankruptcy status can be added to the Dow Jones U.S. Real Estate Index on a quarterly basis. For former special purpose acquisition companies ("**SPACs**") that transition to operating companies, S&P Dow Jones considers the de-SPAC transaction to be an equivalent event to an IPO. The inclusion criteria is identical to the criteria used at the annual reconstitution. Market cap and liquidity are evaluated as of the reference date. Any stocks considered for addition at the quarterly rebalancing must have an FMC larger than that of the smallest stock included in the Dow Jones U.S. Real Estate Index at the time of the previous reconstitution. In addition, the stock must have a trading history of at least three months as of the reference date. Since the stocks will have traded less than a full year, the trading value data that is available is annualized to determine index eligibility. The reference date for quarterly inclusions is five weeks prior to the effective rebalancing date, and additions are effective at the open of Monday following the third Friday of March, June, September, and December.

*Spin-offs.* Spin-offs from current index constituents are eligible for index inclusion and are included in the Dow Jones U.S. Real Estate Index on their ex-dates. Spin-offs are assigned the same size and style as the parent company at the time of the event. All spin-off sizes are evaluated at the next quarterly review.

*Deletions.* Between rebalancings, a company can be deleted from the Dow Jones U.S. Real Estate Index due to corporate events such as mergers, acquisitions, takeovers, delistings or bankruptcies. A company is deleted from the Dow Jones U.S. Real Estate Index if it is involved in a merger, acquisition, or significant restructuring such that it no longer meets the eligibility criteria. If a company's shares are no longer available or are no longer trading, the company is deleted from the Dow Jones U.S. Real Estate Index as soon as reasonably possible providing that five days' notice is given. In the event the information of delisting, bankruptcy or ineligible status becomes public after the fact, the stock may be removed with a one-day notice period.

*Corporate Actions*. Corporate actions (such as stock splits, stock dividends, spin-offs and rights offerings) are applied after the close of trading on the day prior to the ex-date. Share changes resulting from exchange offers are applied on the ex-date.

*Governance of the Dow Jones U.S. Real Estate Index*

An S&P Dow Jones index committee maintains the Dow Jones U.S. Real Estate Index. All committee members are full-time professional members of S&P Dow Jones's staff. The index committee meets regularly. At each meeting, the index committee may review pending corporate actions that may affect index constituents, statistics comparing the composition of the Dow Jones U.S. Real Estate Index to the market, companies that are being considered as candidates for addition to the Dow Jones U.S. Real Estate Index, and any significant market events. In addition, the index committee may revise index policy covering rules for selecting companies, treatment of dividends, share counts or other matters.

In seeking to track the performance of the relevant Select Sector Index, each Select Sector Fund employs a replication strategy, which means that each Select Sector Fund typically invests in substantially all of the securities represented in the relevant Select Sector Index in approximately the same proportions as that Select Sector Index. However, under various circumstances, it may not be possible or practical to purchase all of the securities in the relevant Select Sector Index, or amounts of those securities in proportion to their weighting in that Select Sector Index. Under these circumstances, SSGA FM intends to employ a sampling strategy in managing the relevant Select Sector Fund. Sampling means that SSGA FM will use quantitative analysis to select securities, including securities in the relevant Select Sector Index, outside of the relevant Select Sector Index and derivatives that have a similar investment profile as the relevant Select Sector Index in terms of key risk factors, performance attributes and other economic characteristics. These include industry weightings, market capitalization and other financial characteristics of securities.

While SSGA FM seeks to track the performance of the relevant Select Sector Index (*i.e.*, achieve a high degree of correlation with the relevant Select Sector Index), each Select Sector Fund's return may not match the return of the relevant Select Sector Index due to operating expenses, transaction costs, cash flows, regulatory requirements and operational inefficiencies.

The Select Sector Trust is a registered investment company that consists of a separate investment portfolio for each of the Select Sector Funds. Information provided to or filed with the SEC by the Select Sector Trust pursuant to the Securities Act of 1933, as amended, and the Investment Company Act of 1940, as amended, can be located by reference to SEC file numbers 333-57791 and 811-08837, respectively, through the SEC's website at http://www.sec.gov.

**The SPDR<sup>®</sup> EURO STOXX 50<sup>®</sup> ETF**

All information contained in this underlying supplement regarding the SPDR<sup>®</sup> EURO STOXX 50<sup>®</sup> ETF (the "**FEZ Fund**") has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, SSGA Funds Management, Inc. ("**SSGA FM**"), the investment advisor for the FEZ Fund. The FEZ Fund is an investment portfolio of SPDR<sup>®</sup> Index Shares Funds and is maintained and managed by SSGA FM. The FEZ Fund is an exchange-traded fund that trades on the NYSE Arca, Inc. under the ticker symbol "FEZ."

The FEZ Fund seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of the EURO STOXX 50<sup>®</sup> Index. For more information about the EURO STOXX 50<sup>®</sup> Index, please see "Equity Index Descriptions—The STOXX Benchmark Indices" in this underlying supplement.

In seeking to track the performance of the EURO STOXX 50<sup>®</sup> Index, the FEZ Fund employs a sampling strategy, which means that the FEZ Fund is not required to purchase all of the securities represented in the EURO STOXX 50<sup>®</sup> Index. Instead, the FEZ Fund may purchase a subset of the securities in the EURO STOXX 50<sup>®</sup> Index in an effort to hold a portfolio of securities with generally the same risk and return characteristics of the EURO STOXX 50<sup>®</sup> Index. The quantity of holdings in the FEZ Fund will be based on a number of factors, including asset size of the FEZ Fund. Based on its analysis of these factors, SSGA FM, either may invest the FEZ Fund's assets in a subset of securities in underlying index or may invest the FEZ Fund's assets in substantially all of the securities represented in the EURO STOXX 50<sup>®</sup> Index in approximately the same proportions as the EURO STOXX 50<sup>®</sup> Index.

While SSGA FM seeks to track the performance of the EURO STOXX 50<sup>®</sup> Index (*i.e.*, achieve a high degree of correlation with the EURO STOXX 50<sup>®</sup> Index), the FEZ Fund's return may not match the return of the EURO STOXX 50<sup>®</sup> Index. The FEZ Fund incurs a number of operating expenses not applicable to the EURO STOXX 50<sup>®</sup> Index, and incurs costs in buying and selling securities. In addition, the FEZ Fund may not be fully invested at times, generally as a result of cash flows into or out of the FEZ Fund or reserves of cash held by the FEZ Fund to meet redemptions. SSGA FM may attempt to replicate the EURO STOXX 50<sup>®</sup> Index return by investing in fewer than all of the securities in the EURO STOXX 50<sup>®</sup> Index, or in some securities not included in the EURO STOXX 50<sup>®</sup> Index, potentially increasing the risk of divergence between the FEZ Fund's return and that of the EURO STOXX 50<sup>®</sup> Index.

SPDR<sup>®</sup> Index Shares Funds is a registered investment company that consists of numerous separate investment portfolios, including the FEZ Fund. Information provided to or filed with the SEC by the FEZ Fund pursuant to the Securities Act of 1933, as amended, and the Investment Company Act of 1940, as amended, can be located by reference to SEC file numbers 333-92106 and 811-21145, respectively, through the SEC's website at http://www.sec.gov.

**The SPDR<sup>®</sup> Gold Trust**

All information contained in this underlying supplement regarding the SPDR<sup>®</sup> Gold Trust (the "**GLD Fund**") has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, the GLD Fund and World Gold Trust Services, LLC ("**World Gold**"), the sponsor of the GLD Fund. The Bank of New York Mellon is the trustee of the GLD Fund, and State Street Global Advisors Funds Distributors, LLC is the marketing agent of the GLD Fund. HSBC Bank plc and JPMorgan Chase Bank, N.A. are the custodians of the GLD Fund. The GLD Fund is an investment trust that trades on the NYSE Arca, Inc. under the ticker symbol "GLD."

The investment objective of the GLD Fund is for its shares to reflect the performance of the price of gold bullion, less the GLD Fund's expenses. The GLD Fund holds gold bars and from time to time, issues blocks of shares in exchange for deposits of gold and distributes gold in connection with the redemption of blocks of shares. The shares of the GLD Fund are designed for investors who want a cost-effective and convenient way to invest in gold.

The shares of the GLD Fund represent units of fractional undivided beneficial interest in and ownership of the GLD Fund. The GLD Fund is a passive investment vehicle and the trustee of the GLD Fund does not actively manage the gold held by the GLD Fund. The trustee of the GLD Fund sells gold held by the GLD Fund to pay the GLD Fund's expenses on an as-needed basis irrespective of then-current gold prices. Currently, the GLD Fund's only recurring fixed expense is World Gold's fee, which accrues daily at an annual rate equal to 0.40% of the daily net asset value of the GLD Fund, in exchange for World Gold assuming the responsibility to pay all ordinary fees and expenses of the GLD Fund.

Information provided to or filed with the SEC by the GLD Fund pursuant to the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, can be located by reference to SEC file numbers 333-267520 and 001-32356, respectively, through the SEC's website at http://www.sec.gov.

The GLD Fund is not a commodity pool for purposes of the Commodity Exchange Act of 1936, as amended, and is not subject to regulation thereunder, and World Gold is not subject to regulation by the Commodity Futures Trading Commission as a commodity pool operator or a commodity trading advisor.

**The SPDR<sup>®</sup> S&P 500<sup>®</sup> ETF Trust**

All information contained in this underlying supplement regarding the SPDR<sup>®</sup> S&P 500<sup>®</sup> ETF Trust (the "**SPY Fund**") has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, State Street Global Advisors Trust Company ("**SSGA TC**"), as trustee of the SPY Fund, and PDR Services LLC ("**PDRS**"), as sponsor of the SPY Fund. The SPY Fund is a unit investment trust that issues securities called "Units." The SPY Fund trades on the NYSE Arca, Inc. under the ticker symbol "SPY."

The SPY Fund seeks to provide investment results that, before expenses, correspond generally to the price and yield performance of the S&P 500<sup>®</sup> Index. For more information about the S&P 500<sup>®</sup> Index, please see "Equity Index Descriptions— The S&P U.S. Indices" in this underlying supplement.

The SPY Fund seeks to achieve its investment objective by holding a portfolio of common stocks that are included in the S&P 500<sup>®</sup> Index, with the weight of each stock in the portfolio substantially corresponding to the weight of that stock in the S&P 500<sup>®</sup> Index. At any time, the portfolio of the SPY Fund will consist of as many of the component stocks of the S&P 500<sup>®</sup> Index as is practicable. To maintain the correspondence between the composition and weightings of the stocks held by the SPY Fund and the component stocks of the S&P 500<sup>®</sup> Index, SSGA TC or its parent company, State Street Bank and Trust Company ("**SSBT**"), adjusts the portfolio of the SPY Fund from time to time to conform to periodic changes in the identity and/or relative weightings of the component stocks of the S&P 500<sup>®</sup> Index. SSGA TC or SSBT aggregates certain of these adjustments and makes changes to the portfolio of the SPY Fund at least monthly, or more frequently in the case of significant changes to the S&P 500<sup>®</sup> Index.

While the SPY Fund is intended to track the performance of the S&P 500<sup>®</sup> Index as closely as possible (*i.e.*, to achieve a high degree of correlation with the S&P 500<sup>®</sup> Index), the return of the SPY Fund may not match or achieve a high degree of correlation with the return of the S&P 500<sup>®</sup> Index due to expenses and transaction costs incurred in adjusting the SPY Fund's portfolio. In addition, it is possible that the SPY Fund may not always fully replicate the performance of the S&P 500<sup>®</sup> Index due to the unavailability of certain component stocks of the S&P 500<sup>®</sup> Index in the secondary market or due to other extraordinary circumstances *(e.g.*, if trading in a security has been halted).

**The SPY Fund is a registered investment company.

Instead, each SPDR Industry ETF may purchase a subset of the securities in the relevant Select Industry Index in an effort to hold a portfolio of securities with generally the same risk and return characteristics as the relevant Select Industry Index. The quantity of holdings in each SPDR Industry ETF will be based on a number of factors, including asset size of that SPDR Industry ETF. Based on its analysis of these factors, SSGA FM may invest each SPDR Industry ETF's assets in a subset of securities in the relevant Select Industry Index or may invest that SPDR Industry ETF's assets in substantially all of the securities represented in the relevant Select Industry Index in approximately the same proportions as the relevant Select Industry Index, as determined by SSGA FM to be in the best interest of that SPDR Industry ETF in pursuing its objective.

While SSGA FM seeks to track the performance of the relevant Select Industry Index (*i.e.*, achieve a high degree of correlation with the relevant Select Industry Index), a SPDR Industry ETF's return may not match the return of the relevant Select Industry Index for a number of reasons. For example, the return on the sample of securities purchased by a SPDR Industry ETF (or the return on securities not included in the relevant Select Industry Index) may not correlate precisely with the return of that Select Industry Index. Each SPDR Industry ETF incurs a number of operating expenses not applicable to the relevant Select Industry Index, and may incur costs in buying and selling securities. In addition, a SPDR Industry ETF may not be fully invested at times, either as a result of cash flows into or out of that SPDR Industry ETF or reserves of cash held by that SPDR Industry ETF to meet redemptions. SSGA FM may attempt to track the relevant Select Industry Index return by investing in fewer than all of the securities in that Select Industry Index, or in some securities not included in that Select Industry Index,

potentially increasing the risk of divergence between a SPDR Industry ETF's return and that of the relevant Select Industry Index. Changes in the composition of the relevant Select Industry Index and regulatory requirements also may impact a SPDR Industry ETF's ability to match the return of the relevant Select Industry Index. SSGA FM may apply one or more "screens" or investment techniques to refine or limit the number or types of issuers included in the relevant Select Industry Index in which a SPDR Industry ETF may invest. Application of such screens or techniques may result in investment performance below that of the relevant Select Industry Index and may not produce results expected by SSGA FM. Index tracking risk may be heightened during times of increased market volatility or other unusual market conditions.

**The United States Oil Fund, LP**

All information contained in this underlying supplement regarding the United States Oil Fund, LP (the "**USO Fund**") has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, United States Commodity Funds LLC ("**USCF**"). The USO Fund is managed and controlled by USCF, a Delaware limited liability company that is registered as a commodity pool operator with the Commodity Futures Trading Commission and is a member of the National Futures Association. The USO Fund, a Delaware limited partnership, is a commodity pool that continuously issues common shares of beneficial interest that trade on the NYSE Arca, Inc. ("**NYSE Arca**") under the ticker symbol "USO."

The investment objective of the USO Fund is for the daily changes in percentage terms of its shares' net asset value to reflect the daily changes in percentage terms of the spot price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the daily changes in the price of a specified short-term futures contract on light, sweet crude oil (the "**benchmark oil futures contract**"), plus interest earned on the USO Fund's collateral holdings, less the USO Fund's expenses. The benchmark oil futures contract is the futures contract on light, sweet crude oil traded on the New York Mercantile Exchange that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case it changes over a ten-day rolling period into the futures contract that is the next month to expire.

The USO Fund seeks to achieve its investment objective by investing primarily in futures contracts for light, sweet crude oil, other types of crude oil, diesel-heating oil, gasoline, natural gas and other petroleum-based fuels that are traded on the New York Mercantile Exchange, ICE Futures Europe and ICE Futures U.S. or other U.S. and foreign exchanges (collectively, "**oil futures contracts**") and to a lesser extent, in order to comply with regulatory requirements, risk mitigation measures, liquidity requirements or in view of market conditions, other oil-related investments such as cash-settled options on oil futures contracts, forward contracts for oil, cleared swap contracts and non-exchange traded (over-the-counter) transactions that are based on the price of oil, other petroleum-based fuels, oil futures contracts and indices based on the foregoing. The USO Fund seeks to achieve its investment objective by investing so that the average daily percentage change in its net asset value for any period of 30 successive valuation days will be within plus/minus ten percent (10%) of the average daily percentage change in the price of the benchmark oil futures contract over the same period.

The daily changes in the price of the USO Fund's shares on the NYSE Arca on a percentage basis may not closely track the daily changes in the spot price of light, sweet crude oil on a percentage basis. This could happen if the price of shares traded on the NYSE Arca does not correlate closely with the value of the USO Fund's net asset value; the changes in the USO Fund's net asset value do not correlate closely with the changes in the price of the benchmark oil futures contract; or the changes in the price of the benchmark oil futures contract do not closely correlate with the changes in the cash or spot price of crude oil. The price relationship between the near month contract to expire and the next month contract to expire that compose the benchmark oil futures contract will vary and may impact the total return over time of the USO Fund's net asset value. In cases in which the near month contract's price is lower than the next month contract's price (a situation known as "contango" in the futures markets), then absent the impact of the overall movement in crude oil prices, the value of the benchmark oil futures contract would tend to decline as it approaches expiration. In cases in which the near month contract's price is higher than the next month contract's price (a situation known as "backwardation" in the futures markets), then absent the impact of the overall movement in crude oil prices, the value of the benchmark contract would tend to rise as it approaches expiration.

Information provided to or filed with the SEC by the USO Fund pursuant to the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, can be located by reference to SEC file numbers 333-272617 and 001-32834, respectively, through the SEC's website at http://www.sec.gov. The USO Fund is not a mutual fund or any other type of investment company within the meaning of the Investment Company Act of 1940, as amended, and is not subject to regulation thereunder.

**The VanEck ETFs**

All information contained in this underlying supplement regarding the VanEck<sup>®</sup> Gold Miners ETF, the VanEck<sup>®</sup> Junior Gold Miners ETF, the VanEck<sup>®</sup> Oil Services ETF and the VanEck<sup>®</sup> Semiconductor ETF (each, a "**VanEck ETF**" and collectively, the "**VanEck ETFs**") has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, VanEck<sup>®</sup> ETF Trust (the "**VanEck Trust**") and Van Eck Associates Corporation ("**Van Eck**"). Each VanEck ETF is an investment portfolio of the VanEck Trust. Van Eck is currently the investment advisor to the VanEck ETFs. Prior to September 2021, VanEck<sup>®</sup> was branded as VanEck Vectors<sup>®</sup>.

Each VanEck ETF uses a "passive" or indexing investment approach to attempt to approximate the investment performance of its underlying index by investing in a portfolio of securities that generally replicates its underlying index.

Each VanEck ETF's return may not match the return of its underlying index for a number of reasons. For example, each VanEck ETF incurs a number of operating expenses, including taxes, not applicable to its underlying index and incurs costs associated with buying and selling securities and entering into derivatives transactions (if applicable), especially when rebalancing that VanEck ETF's securities holdings to reflect changes in the composition of its underlying index, which are not factored into the return of its underlying index. Transaction costs, including brokerage costs, will decrease a VanEck ETF's net asset value ("**NAV**") to the extent not offset by the transaction fee payable by an authorized participant. Market disruptions and regulatory restrictions could have an adverse effect on a VanEck ETF's ability to adjust its exposure to the required levels in order to track its underlying index. A VanEck ETF may not be fully invested at times either as a result of cash flows into that VanEck ETF or reserves of cash held by that VanEck ETF to pay expenses or to meet redemptions. In addition, a VanEck ETF may not be able to invest in certain securities included in its underlying index, or invest in them in the exact proportions in which they are represented in its underlying index. A VanEck ETF's performance may also deviate from the return of its underlying index due to legal restrictions or limitations imposed by the governments of certain countries, certain listing standards of that VanEck ETF's listing exchange, a lack of liquidity on stock exchanges in which the securities trade, potential adverse tax consequences or other regulatory reasons or legal restrictions or limitations (such as diversification requirements). A VanEck ETF may value certain of its investments and/or other assets based on fair value prices. To the extent a VanEck ETF calculates its NAV based on fair value prices and the value of its underlying index is based on securities' closing prices (*i.e.*, the value of its underlying index is not based on fair value prices), that VanEck ETF's ability to track its underlying index may be adversely affected. In addition, any issues a VanEck ETF encounters with regard to currency convertibility (including the cost of borrowing funds, if any) and repatriation may also increase the index tracking risk. A VanEck ETF's performance may also deviate from the performance of its underlying index due to the impact of withholding taxes, late announcements relating to changes to its underlying index and high turnover of the underlying index. When markets are volatile, the ability to sell securities at fair value prices may be adversely impacted and may result in additional trading costs and/or increase the index tracking risk. For tax efficiency purposes, a VanEck ETF may sell certain securities, and this sale may cause that VanEck ETF to realize a loss and deviate from the performance of its underlying index. In light of the factors discussed above, a VanEck ETF's return may deviate significantly from the return of its underlying index. Changes to the composition of its underlying index in connection with a rebalancing or reconstitution of its underlying index may cause a VanEck ETF to experience increased volatility, during which time that VanEck ETF's index tracking risk may be heightened.

The VanEck Trust is a registered investment company that consists of numerous separate investment portfolios, including the VanEck ETFs. Information provided to or filed with the SEC by the VanEck Trust pursuant to the Securities Act of 1933, as amended, and the Investment Company Act of 1940, as amended, can be located by reference to SEC file numbers 333-123257 and 811-10325, respectively, through the SEC's website at http://www.sec.gov.

***The MarketVector Global Gold Miners Index***

All information contained in this underlying supplement regarding the Gold Miners 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, MarketVector Indexes GmbH ("**MarketVector**"). The Gold Miners Index is owned by MarketVector and is calculated and maintained by Solactive AG ("**Solactive**"). MarketVector and Solactive have no obligation to continue to publish, and may discontinue publication of, the Gold Miners Index.

The Gold Miners Index is reported by Bloomberg L.P. under the ticker symbol "MVGDX."

The Gold Miners Index is a float-adjusted modified market capitalization-weighted index that tracks the performance of companies involved primarily in the gold and silver mining industry. The Gold Miners Index was launched on June 3, 2025 with a base index value of 1000.00 as of April 30, 2006.

*Index Composition*

*Index Universe*

To be eligible for inclusion in the Gold Miners Index, companies must generate at least 50% (25% for current index components) of their revenues from gold and/or silver mining, royalties and/or streaming or have at least 50% (25% for current index components) of their mining mineral resources from gold and/or silver. In addition, securities must be common securities or securities with similar characteristics from financial markets that are freely investable for foreign investors and that provide real-time and historical component and currency pricing, excluding limited partnerships. Companies from financial markets that are not freely investable for foreign investors or that do not provide real-time and historical component and currency pricing may still be eligible if they have a listing on an eligible exchange and if they meet all the size and liquidity requirements set forth below on that exchange.

Securities are not eligible for inclusion in the Gold Miners Index if they are listed on (1) exchanges in Bahrain, China (domestic market), India, Kuwait, Luxembourg, Oman, Qatar, Russia, Saudi Arabia, United Arab Emirates or Vietnam or (2) Paris Euronext Auction, Hamburger Boerse, Boerse Berlin, Oslo Euronext Growth or London Stock Exchange (AIM, AIMI, ASQ1, ASQ2, ASX1, ASXN, SFM2, SFM3, SSQ3, SSX3, SSX4, EQS).

*Investable Universe*

To be included in the investable universe, securities must meet the following size and liquidity requirements:

&nbsp;&nbsp;&nbsp;&nbsp;1. For securities that are currently not included in the Gold Miners Index, the securities must have (i) free-float of at least 10%,
(ii) full market capitalization exceeding $150 million, (iii) a three-month average daily trading volume of at least $1 million at the
current quarter and at the previous two quarters and (iv) at least 0.25 million shares traded per month over the last six months at the
current quarter and at the previous two quarters.

&nbsp;&nbsp;&nbsp;&nbsp;2. For securities that are already included in the Gold Miners Index, the securities must have (i) free-float of at least 5%, (ii) full
market capitalization exceeding $75 million, (iii) a three-month average daily trading volume of at least $0.2 million in at least two
of the latest three quarters (current quarter and the previous two quarters) and (iv) at the current quarter or at one of the previous
two quarters, a three-month average daily trading volume of at least $0.6 million or at least 0.2 million shares traded per month over
the last six months.

&nbsp;&nbsp;&nbsp;&nbsp;3. In the case of recent initial public offerings, spin-offs and post-merger/acquisition special purpose acquisition companies, the securities
must have (i) free-float of at least 10%, (ii) full market capitalization exceeding $150 million, (iii) an average daily trading volume
of at least $1 million and (iv) traded at least 0.25 million shares per month (or per 22 days).

Such securities qualify for fast-track addition to the investable universe once; either at the next regularly scheduled review if they have been trading since at least the last trading day of the month two months prior to the review month or else at the following regularly scheduled review.

*Eligible Universe*

For each company in the investable universe, only one share class is included in the eligible universe. In cases where more than one share class fulfills the above specified market capitalization and liquidity eligibility criteria, only the largest share class by free-float market capitalization is included in the eligible universe. In exceptional cases (e.g. significantly higher liquidity), MarketVector can decide that a different share class will be included in the eligible universe. In cases where the free-float market capitalization of a currently not included share class of an index component exceeds the free-float market capitalization of the currently selected share class by at least 25% and fulfills all market capitalization and liquidity eligibility criteria for non-components, the currently selected share class will be replaced by the larger one. In exceptional cases (e.g. significantly higher liquidity), MarketVector can decide to keep the current share class instead.

For each company in the investable universe, one pricing source qualifies for the eligible universe. In cases where a company has multiple listings (e.g. ADRs, GDRs or listing on markets other than in the home country), the price sources will be selected to the eligible universe in the following order: U.S. price source, UK price source (London Stock Exchange International Order Book only), home market price source and most liquid foreign market price source. Once a company has qualified for the investable universe, only the most liquid single exchange price source within the country qualifies for the eligible universe. In exceptional cases, MarketVector can assign alternative pricing sources.

*Selection of Index Components*

Upon an index reconstitution, securities included in the eligible universe are selected for inclusion in the Gold Miners Index based on the following procedure. The Gold Miners Index targets a coverage of 90% of the free-float market capitalization of the eligible universe with a minimum of 25 components.

&nbsp;&nbsp;&nbsp;&nbsp;1. All securities in the eligible universe are sorted in terms of free-float market capitalization in descending order.

&nbsp;&nbsp;&nbsp;&nbsp;2. Securities covering the top 85% of the free-float market capitalization of the eligible universe qualify for selection.

&nbsp;&nbsp;&nbsp;&nbsp;3. Current components between 85% and 98% of the free-float market capitalization of the eligible universe also qualify for selection.

&nbsp;&nbsp;&nbsp;&nbsp;4. If the coverage is still below 90% of the free-float market capitalization of the eligible universe or the number of components in
the Gold Miners Index is still below 25, the largest remaining securities will be selected until both the target coverage and minimum
number of components are reached.

&nbsp;&nbsp;&nbsp;&nbsp;5. If the number of eligible securities is below the minimum of 25, additional securities will be added by MarketVector's decision
until the number of securities selected to the Gold Miners Index reaches the minimum of 25.

*Weighting of Index Components*

Upon an index rebalance, components selected for inclusion in the Gold Miners Index will be weighted according to a modified float-adjusted market cap weighting methodology:

&nbsp;&nbsp;&nbsp;&nbsp;1. All index components are weighted by their free-float market capitalization.

&nbsp;&nbsp;&nbsp;&nbsp;2. At least the largest five and at most the largest 9 of the components with more than 50% exposure to gold-related activities that
exceed 4.5% in weight are grouped together (so called "Large-Weights"). All other components are grouped together as well
(so called "Small-Weights").

&nbsp;&nbsp;&nbsp;&nbsp;3. The aggregated weighting of the Large-Weights is capped at 45%. If the aggregated weighting of the Large-Weights exceeds 45%, then
a capping factor is calculated to bring the weighting down to 45%, and a second capping factor is calculated to bring the aggregated weighting
of the Small-Weights up to 55%. These two factors are then applied to all components in the Large-Weights or the Small-Weights, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;4. For the Large-Weights, the maximum weight for any single security is 20% and the minimum weight is 5%. If a security is above the
maximum weight or below the minimum weight, then the weight will be reduced to the maximum weight or increased to the minimum weight and
the excess weight will be redistributed proportionally across all other remaining components in the Large-Weights.

&nbsp;&nbsp;&nbsp;&nbsp;5. For the Small-Weights, the maximum weight for any single security is 4.5%. If a security is above the maximum weight, then the weight
will be reduced to the maximum weight and the excess weight will be redistributed proportionally across all other remaining components
in the Small-Weights.

&nbsp;&nbsp;&nbsp;&nbsp;6. The aggregated weighting of all components with less than 50% exposure to gold-related activities is capped at 20%. Any excess weight
will be redistributed proportionally among the uncapped components with more than 50% exposure to gold-related activities in the Small-Weights.

*Index Reconstitution and Rebalance*

The Gold Miners Index is reconstituted and rebalanced on a quarterly basis in March, June, September and December according to the following schedule:

&nbsp;&nbsp;&nbsp;&nbsp;1. The eligible universe and component selection is determined based on the closing data on the last business day in February, May, August
and November. If a security does not trade on the last business day in February, May, August or November, the last available price for
this security will be used.

&nbsp;&nbsp;&nbsp;&nbsp;2. Component weights are determined based on the closing data as of the Wednesday prior to the second Friday of March, June, September
and December. If a security does not trade on the Wednesday prior to the second Friday of March, June, September or December, the last
available price for this security will be used.

&nbsp;&nbsp;&nbsp;&nbsp;3. The underlying review and rebalance data (i.e. weights, shares outstanding, free-float factors and new weighting cap factors) is announced
on the second Friday of March, June, September and December.

&nbsp;&nbsp;&nbsp;&nbsp;4. Changes will be implemented and based on the closing prices as of the third Friday of March, June, September and December. If the
third Friday is not a business day, the review will take place on the last business day before the third Friday. If a security does not
trade on the third Friday of March, June, September or December, the last available price for this security will be used. Changes become
effective on the next index dissemination day.

*Index Calculation*

The Gold Miners Index is calculated on weekdays between 01:00 and 22:40 (CET) and index values are disseminated to data vendors every 15 seconds on days when either the U.S. equity market is open for trading or at least one of the index components is available for trading. Real-time index values are calculated with the midpoint between the latest available real-time bid- and ask-prices. Closing values are calculated at 22:40 (CET) with fixed 16:00 London time exchange rates from WM company.

The Gold Miners Index's index level on a given day is calculated as the sum of the free-float market capitalization of the index components in U.S. dollars *divided by* the divisor. The Gold Miners Index is free-float adjusted, meaning the number of shares outstanding is reduced to exclude closely held shares (amount larger than 5% of the company's full market capitalization) from the index calculation. Free-float factors are reviewed quarterly. The divisor is a mathematical factor defined at the inception of the Gold Miners Index and is adjusted upon certain corporate actions and index rebalances.

The Gold Miners Index is calculated as a price return index and does not include in the index calculation dividend payments except for special dividends from non-operating income or cash dividends that are either declared as special or extraordinary or that do not coincide with the company's regular dividend distribution schedule.

*Index Maintenance*

The composition of the Gold Miners Index will be adjusted to reflect changes to free-float factors and number of shares, changes due to mergers and takeovers and changes due to spin-offs. On an ongoing basis, for all corporate events that result in a security deletion from the Gold Miners Index, the deleted security will be replaced with the highest ranked non-component on the most recent selection list immediately only if the number of components in the Gold Miners Index would drop below 20. The replacement security will be added at the same weight as the deleted security, unless the number of index components drops below the minimum component number due to a merger of two or more index components, in which case the replacement security will be added with its uncapped free-float market capitalization weight. If there is no replacement, the additional weight resulting from the deletion will be redistributed proportionally across all other index constituents. If the number of index components drops below the minimum component number and no non-component security is eligible as a replacement, the determination of the addition is subject to MarketVector's decision.

*Index Oversight*

Any changes to the index methodology will be reviewed and approved by MarketVector's Legal and Compliance Department. In cases of material changes, an advance notice will be published and provided to users.

***The MVIS<sup>®</sup> Indices***

This information reflects the policies of, and is subject to change by, MarketVector Indexes GmbH ("**MVIS**"). The MVIS Indices were developed by MVIS and are maintained and published by MVIS. Each MVIS Index is calculated by Solactive AG. MVIS has no obligation to continue to publish, and may discontinue publication of, any of the MVIS Indices.

*The MVIS<sup>®</sup> Global Junior Gold Miners Index*

The Junior Gold Miners Index is designed to track the performance of small-capitalization companies involved in the gold and silver mining industry, which includes companies that derive at least 50% (25% for current components) of their revenues from gold mining, royalties or streaming, silver mining, royalties or streaming and/or with mining projects that have the potential to generate at least 50% of their revenues from gold and/or silver when developed. The Junior Gold Miners Index was launched on August 31, 2009 with a base index value of 1,000 as of December 31, 2003. The net total return version of the Junior Gold Miners Index is reported by Bloomberg L.P. under the ticker symbol "MVGDXJTR."

*The MVIS<sup>®</sup> US Listed Oil Services 25 Index*

The Oil Services Index is designed to track the performance of the largest and most liquid U.S.-listed companies that derive at least 50% (25% for current components) of their revenues from oil services to the upstream oil sector, including companies engaged primarily in oil equipment, oil services and/or oil drilling. The Oil Services Index was launched on August 12, 2011 with a base index value of 1,000 as of September 29, 2000. The net total return version of the Oil Services Index is reported by Bloomberg L.P. under the ticker symbol "MVOIHTR."

*The MVIS<sup>®</sup> US Listed Semiconductor 25 Index*

The Semiconductor Index is designed to track the performance of the largest and most liquid U.S.-listed companies that derive at least 50% (25% for current components) of their revenues from semiconductors. This includes companies engaged primarily in the production of semiconductors and semiconductor equipment. The Semiconductor Index was launched on August 12, 2011 with a base index value of 1,000 as of September 29, 2000. The net total return version of the Semiconductor Index is reported by Bloomberg L.P. under the ticker symbol "MVSMHTR."

*MVIS Index Composition and Maintenance*

Index Universe

The index universe for each MVIS Index includes only common stocks and stocks with similar characteristics from financial markets that are freely investable for foreign investors and that provide real-time and historical component and currency pricing. Limited partnerships are excluded. In the case of the Junior Gold Miners Index, companies from financial markets that are not freely investable for foreign investors or that do not provide real-time and historical component and currency pricing may still be eligible if they have a listing on an eligible exchange and if they meet all the size and liquidity requirements on that exchange. Only stocks that have a full market capitalization exceeding US$50 million are eligible for the index universe.

Investable Index Universe

Only companies with a free float (or shares available to foreign investors) of 5% or more for existing index components or 10% or more for new components are eligible for inclusion in an MVIS Index. In addition, stocks that are currently not in the relevant MVIS Index must meet the following size and liquidity requirements:

&nbsp;&nbsp;&nbsp;&nbsp;· a full market capitalization exceeding US$150 million;

&nbsp;&nbsp;&nbsp;&nbsp;· a three-month average-daily-trading volume of at least US$1 million at the
current review and also at the previous two reviews; and

&nbsp;&nbsp;&nbsp;&nbsp;· at least 250,000 shares traded per month over the last six months at the
current review and also at the previous two reviews.

For stocks already in the relevant MVIS Index the following applies:

&nbsp;&nbsp;&nbsp;&nbsp;· a full market capitalization exceeding US$75 million;

&nbsp;&nbsp;&nbsp;&nbsp;· a three-month average-daily-trading volume of at least US$0.2 million in
at least two of the latest three quarters (current review and also at the previous two reviews); and

&nbsp;&nbsp;&nbsp;&nbsp;· a three-month average-daily-trading volume of at least US$0.6 million at
the current review or at one of the previous two reviews; or at least 200,000 shares traded per month over the last six months at the
current review or at one of the previous two reviews.

Only one share line of each company is eligible. If more than one share line fulfills the above size and liquidity rules, only the largest share line by free float market capitalization is eligible. MVIS can, in exceptional cases (e.g., significantly higher liquidity), decide for a different share line.

If the free float market capitalization of a non-component share line:

&nbsp;&nbsp;&nbsp;&nbsp;· exceeds the free float market capitalization of a share line of the same
company which is an index component by at least 25%; and

&nbsp;&nbsp;&nbsp;&nbsp;· fulfills all size and liquidity eligibility criteria for non-components,

the current component share line will be replaced by the larger one. MVIS can, in exceptional cases (*e.g.*, significantly higher liquidity), decide to keep the current share line instead.

*Junior Gold Miners Index Constituent Selection*

The Junior Gold Miners Index is reconstituted on a semi-annual basis in March and September. The target coverage of the Junior Gold Miners Index is 100% of the free float market capitalization of the investable universe of small-cap gold and silver mining companies, with a minimum of 25 components. The constituents of the Junior Gold Miners Index are selected using the following procedure:

&nbsp;&nbsp;&nbsp;&nbsp;(1) Companies are valued by full market capitalization (all secondary lines are grouped). All companies (and not securities) are sorted
by full market capitalization in descending order.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Companies covering the top 60% of the full market capitalization are excluded. Only companies ranking between 60% and 98% qualify
for the selection. However, existing components ranking between 55% and 60% or 98% and 99% also qualify for the selection.

&nbsp;&nbsp;&nbsp;&nbsp;(3) All companies which qualified in step 2 are now viewed as securities (companies with secondary lines are ungrouped and treated separately).
Only securities that meet all requirements of the investable index universe are added to the Junior Gold Miners Index.

&nbsp;&nbsp;&nbsp;&nbsp;(4) In case the number of eligible companies is below 25, additional companies are added by MVIS's decision until the number of
stocks equals 25.

In addition to the periodic reviews, the Junior Gold Miners Index is continually reviewed for corporate events (*e.g.*, mergers, takeovers, spin-offs, delistings and bankruptcies) that affect the index components.

*MVIS US Listed 25 Index Constituent Selection*

Each of the Oil Services Index and the Semiconductor Index (each, an "**MVIS US Listed 25 Index**" and collectively, the "**MVIS US Listed 25 Indices**") is reconstituted on a semi-annual basis in March and September. The target coverage of each MVIS US Listed 25 Index is 25 companies from the investable universe that are U.S. exchange-listed companies that derive at least 50% (25% for current components) of their revenues from the relevant sector or sectors for that MVIS US Listed 25 Index. The constituents of each MVIS US Listed 25 Index are selected using the following procedure:

&nbsp;&nbsp;&nbsp;&nbsp;(1) The largest 50 stocks (by full market capitalization) from the investable universe that are U.S. exchange-listed companies that derive
at least 50% (25% for current components) of their revenues from the relevant sector or sectors for that MVIS US Listed 25 Index qualify.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The 50 stocks are ranked in two different ways — by free float market capitalization in descending
order (the largest company receives rank "1") and then by three-month average-daily-trading volume in descending order
(the most liquid company receives rank "1"). These two ranks are added together.

&nbsp;&nbsp;&nbsp;&nbsp;(3) The 50 stocks are then ranked by the sum of their two ranks in Step 2 in ascending order. If
two companies have the same sum of ranks, the larger company is placed on top.

&nbsp;&nbsp;&nbsp;&nbsp;(4) Initially, the highest ranked 25 companies made up the relevant MVIS US Listed 25 Index. On an ongoing
basis, a 10-40 buffer is applied: the highest ranked 10 companies qualify. The remaining 15 companies are selected from the highest
ranked remaining current index components ranked between 11 and 40.

&nbsp;&nbsp;&nbsp;&nbsp;(5) If the number of selected companies is still below 25, then the highest ranked remaining stocks are
selected until 25 companies have been selected.

&nbsp;&nbsp;&nbsp;&nbsp;(6) If the number of eligible securities is below 25, additional securities are added by MVIS's
decision until the number of selected companies equals the minimum component count.

In addition to the periodic reviews, each MVIS US Listed 25 Index is continually reviewed for corporate events (*e.g.*, mergers, takeovers, spin-offs, delistings and bankruptcies) that affect the index components.

*MVIS Index Calculation*

The value of each MVIS Index is calculated using the Laspeyres' formula, rounded to two decimal places, with stock prices converted to U.S. dollars:

where (for all stocks (i) in the relevant MVIS Index):

p<sub>i</sub> = stock price (rounded to four decimal places);

q<sub>i</sub> = number of shares;

ff<sub>i</sub> = free float factor (rounded to two decimal places);

fx<sub>i</sub> = exchange rate (local currency to U.S. Dollar) (rounded to 12 decimal places);

cf<sub>i</sub> = weighting cap factor (if applicable, otherwise set to 1) (rounded to 16 decimal places);

M = free float market capitalization of the relevant MVIS Index; and

D = divisor (rounded to six decimal places).

*Free Float*

Each MVIS Index is free float-adjusted — that is, the number of shares outstanding is reduced to exclude closely held shares (amount larger than 5% of the company's full market capitalization) from the index calculation. At times, other adjustments are made to the share count to reflect foreign ownership limits or sanctions. These are combined with the block-ownership adjustments into a single factor. To avoid unwanted double counting, either the block-ownership adjustment or the restricted stocks adjustment is applied, whichever produces the higher result. Free float factors are reviewed quarterly.

*Junior Gold Miners Index Weighting Cap Factors*

The Junior Gold Miners Index is rebalanced quarterly in March, June, September and December. Components are weighted according to their free float market capitalization, as modified by the weighting cap factors. The Junior Gold Miners Index uses the weighting cap factors to ensure diversification to avoid overweighting.

The following weighting scheme is applied in quarters when the index is reconstituted and rebalanced:

&nbsp;&nbsp;&nbsp;&nbsp;· All companies are ranked by their free float market capitalization. The top
five stocks get the following weights:

The largest stock's weight will be fixed to 7%.

The 2nd largest stock's weight will be fixed to 6.5%.

The 3rd largest stock's weight will be fixed to 6%.

The 4th largest stock's weight will be fixed to 5.5%.

The 5th largest stock's weight will be fixed to 5%.

&nbsp;&nbsp;&nbsp;&nbsp;· The aggregate weight of the remaining stocks is 70%. The maximum weight allowed
for the remaining stocks is 4.5%. If a stock exceeds the maximum weight, the weight will be reduced to the maximum weight and the excess
weight will be redistributed proportionally across the index constituents out of the top 5 stocks. This process is repeated until no stocks
have weights exceeding the maximum weight.

&nbsp;&nbsp;&nbsp;&nbsp;· The maximum weight for silver stocks is 4.5% and the weight of silver stocks
in total must not constitute more than 20% of the index. In this case a sector-weighting cap factor will be applied which is calculated
to ensure that the aggregate weight of all gold stocks will not be less than 80% and the aggregate weighting of all silver stocks will
not be greater than 20%.

The following scheme is applied in the quarters in which the index is rebalanced:

&nbsp;&nbsp;&nbsp;&nbsp;· The top five stocks from the previous index review receive the same weights
as of the previous review. The rest of companies are ranked by their free float market capitalization.

&nbsp;&nbsp;&nbsp;&nbsp;· In case one of the top five components of the previous index review does
not exist anymore in the current rebalance, the subsequent company in the rank will move up in rank until there is a fixed list of top
five components.

&nbsp;&nbsp;&nbsp;&nbsp;· The aggregate weight of the remaining stocks is 70%. The maximum weight allowed
for the remaining stocks is 4.5%. If a stock exceeds the maximum weight, the weight will be reduced to the maximum weight and the excess
weight shall be redistributed proportionally across the index constituents out of the top 5 stocks. This process is repeated until no
stocks have weights exceeding the maximum weight.

&nbsp;&nbsp;&nbsp;&nbsp;· The maximum weight for silver stocks is 4.5% and the weight of silver stocks
in total must not constitute more than 20% of the index. In this case a sector-weighting cap factor will be applied which is calculated
to ensure that the aggregate weight of all gold stocks will not be less than 80% and the aggregate weighting of all silver stocks will
not be greater than 20%.

*MVIS US Listed 25 Index Weighting Cap Factors*

Each MVIS US Listed 25 Index is rebalanced quarterly in March, June, September and December. Companies in each MVIS US Listed 25 Index are weighted according to their free float market capitalization, as modified by the weighting cap factors. The MVIS US Listed 25 Indices use the weighting cap factors to ensure diversification to avoid overweighting.

The following weighting scheme applies to the MVIS US Listed 25 Indices:

&nbsp;&nbsp;&nbsp;&nbsp;· All index components are weighted by their free float market capitalization.

&nbsp;&nbsp;&nbsp;&nbsp;· All companies exceeding 4.5% but at least the largest five companies and
at the maximum the largest 10 companies are grouped together (so called "**Large-Weights** "). All other companies are grouped
together as well (so called "**Small-Weights** ").

&nbsp;&nbsp;&nbsp;&nbsp;· The aggregated weighting of the Large-Weights is capped at 50%:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Large-Weights: If the aggregated weighting of all companies in Large-Weight exceeds 50%, then a capping factor is calculated to bring
the weighting down to 50%; at the same time, a second capping factor for the Small-Weights is calculated to increase the aggregated weight
to 50%. These two factors are then applied to all companies in the Large-Weights or the Small-Weights respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Large-Weights: The maximum weight for any single stock is 20% and the minimum weighting is 5%. If a stock is above the maximum or
below the minimum weight, then the weight will be reduced to the maximum weight or increased to the minimum weight and the excess weight
will be re-distributed proportionally across all other remaining index constituents in the Large-Weights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Small-Weights: The maximum weight for any single stock is 4.5%. If a stock is above the maximum weight, then the weight will be reduced
to the maximum weight and the excess weight will be re-distributed proportionally across all other remaining index constituents in the
Small-Weights.

*Divisor Adjustments*

Index maintenance (reflecting changes in, e.g., shares outstanding, capital actions, addition or deletion of stocks to the relevant MVIS Index) should not change the level of an MVIS Index. This is accomplished with an adjustment to the divisor. Any change to the stocks in the relevant MVIS Index that alters the total market value of that MVIS Index while holding stock prices constant will require a divisor adjustment.

The Vanguard FTSE Emerging Markets ETF employs an indexing investment approach designed to track the Emerging Markets Index. The Vanguard FTSE Emerging Markets ETF invests by sampling the Emerging Markets Index, meaning that it holds a broadly diversified collection of securities that, in the aggregate, approximates the Emerging Markets Index in terms of key characteristics. These key characteristics include industry weightings and market capitalization, as well as certain financial measures, such as price/earnings ratio and dividend yield. The Vanguard FTSE Emerging Markets ETF is subject to index sampling risk, which is the chance that the securities selected for the Vanguard FTSE Emerging Markets ETF, in the aggregate, will not provide investment performance matching that of the Emerging Markets Index. In addition, the Vanguard FTSE Emerging Markets ETF has operating expenses and transaction costs while the Emerging Markets Index does not.

**The FTSE Emerging Markets All Cap China A Inclusion Index**

All information in this underlying supplement regarding the Emerging Markets 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 FTSE Russell. FTSE Russell has no obligation to continue to publish, and may discontinue publication of, the Emerging Markets Index.

The Emerging Markets Index is a market-capitalization weighted index representing the performance of large-, mid- and small-capitalization companies in emerging markets. The Emerging Markets Index was launched on June 5, 2015, with a base date of December 30, 2005 and a base value of 1,000. The Emerging Markets Index is currently composed of securities from 24 different countries.

The Emerging Markets Index applies the same methodology as the FTSE Emerging Markets Index, except that the Emerging Markets Index includes small-capitalization stocks and China A-shares at a weighting equivalent to the aggregate qualified foreign institutional investor ("QFII") and/or Renminbi QFII ("RQFII") approved quota for international investors. China A-shares, which are securities of Chinese-incorporated companies that trade on either the Shanghai or Shenzhen stock exchange, are quoted in Renminbi and can be traded only either by residents of the People's Republic of China or under the QFII or RQFII rules and stock connect schemes. The China A-shares weighting will increase as total QFII and RQFII allocations increase. A built-in mechanism ensures that the allocation of China A-shares is adjusted proportional to the changes in the approved quota and is in line with the accessibility available to international investors. For more information about the FTSE Emerging Markets Index, see "The FTSE Emerging Markets Index" below.

**The FTSE Emerging Markets Index**

All information in this underlying supplement regarding the FTSE Emerging Markets 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 FTSE International Limited ("FTSE"). FTSE Russell has no obligation to continue to publish, and may discontinue publication of, the FTSE Emerging Markets Index.

The FTSE Emerging Markets Index is included in the FTSE Global Equity Index Series. The FTSE Global Equity Index Series covers securities in 48 different countries. It attempts to represent every equity and sector relevant to international investors' needs and has a modular structure. The universe is divided into Developed, Advanced Emerging and Secondary Emerging segments, with indexes calculated at regional, national and sector level. The FTSE Emerging Markets Index is the aggregate of the Advanced and Secondary Emerging segments of the FTSE Global Equity Index Series universe.

***Country Inclusion Criteria***

FTSE classifies countries included in its global indices into one of three categories: Developed, Advanced Emerging and Secondary Emerging. FTSE maintains a set of criteria to assess market status and minimum standards for each category for countries and markets to achieve in order to be eligible for that category. The minimum standards increase from Secondary Emerging to Advanced Emerging and from Advanced Emerging to Developed. A country will be classified under the category with the highest standards that it meets. FTSE conducts an annual review of all countries included in its global indices and those being considered for inclusion. A country's classification as Developed, Advanced Emerging or Secondary Emerging is dependent on the following criteria:

&nbsp;&nbsp;&nbsp;&nbsp;· Market and regulatory environment: formal stock market regulatory authorities
actively monitor the market; fair and non-prejudicial treatment of minority shareholders; no or selective incidence of foreign
ownership restrictions; no objection to or significant restrictions or penalties applied to the investment of capital or the repatriation
of capital and income; no or simple registration process for foreign investors.

&nbsp;&nbsp;&nbsp;&nbsp;· Foreign exchange market: developed foreign exchange market.

&nbsp;&nbsp;&nbsp;&nbsp;· Equity market: sufficient competition to ensure high-quality broker services;
implicit and explicit costs to be reasonable and competitive; stock lending permitted; short sales permitted; developed derivatives market;
off-exchange transactions permitted; efficient trading mechanism; market depth information/visibility and timely trade reporting process.

&nbsp;&nbsp;&nbsp;&nbsp;· Custody and settlement: rare incidence of failed trades in settlement; settlement
cycle; central securities depositary; central counterparty clearinghouse; free delivery available; sufficient competition to ensure high-quality
custodian services; account structure operating at the custodian level (securities and cash).

Once a country has met the required standards, it will be eligible for inclusion in the FTSE Global Equity Index Series. However, for a country index to be constructed and included in the FTSE Global Equity Index Series, a minimum of 5 companies must pass the securities eligibility criteria and screens for index inclusion. An existing country index will remain in the FTSE Global Equity Index Series while any eligible constituents representing the country remain within the index. On the deletion of the last constituent, the country will continue to be eligible, but the country index will be immediately removed from the FTSE Global Equity Index Series and will only be reconsidered for index inclusion if it meets the minimum requirement of 3 eligible companies.

FTSE Russell conducts an annual review of all countries included in its global indices and those being considered for possible inclusion. Countries already in the indices will be assessed against the minimum standards for each category and prior to any reclassification or removal from the index will be placed on a watch-list. Countries not in the index will be assessed against the minimum standards for each category and, if appropriate, will be added to the watch list for possible future inclusion to one of the categories. In conducting the annual review, FTSE Russell will consult the FTSE Russell Country Classification Advisory Committee. In March and September of each year, FTSE will publish a watch list of countries being monitored for possible promotion or demotion. FTSE Russell releases the results of its annual review in September of each year. FTSE Russell will normally give

at least six months' notice before changing the classification of any country. Countries may be added to the indices at any time after a prior announcement. New regional indices may be added at any time after a prior announcement. Companies in the newly added countries will be reviewed in line with the relevant semi-annual regional review and any changes implemented after a prior announcement.

***Determining Nationality***

A company will be allocated to a single country. If a company is incorporated in one country and has its sole listing in the same country, FTSE Russell will allocate the company to that country. In all other circumstances, FTSE Russell will base its decision on an assessment of various factors including, but not necessarily limited to, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The investor protection regulations present in the country of incorporation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The country in which the company is domiciled for tax purposes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The location of its factors of production;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The location of its headquarters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The location of company meetings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The composition of its shareholder base;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The membership of its board of directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The currency denomination of the company's shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The perception of investors.

If a company is incorporated in a country, has a listing in that country and listings in other countries, FTSE Russell will normally assign the company to the country of incorporation. If the company fails FTSE Russell's liquidity test in the country of incorporation, FTSE Russell may assign the company to the country which exhibits the greatest liquidity. However, save for certain exceptions, a company incorporated in a country other than a developed country (as classified in the FTSE Global Equity Index Series) may not be assigned to a developed country. If a company is incorporated in a country, and is listed only in countries other than the country of incorporation, FTSE Russell will normally allocate the company to the country with the greatest liquidity. If a company is incorporated in a country other than a developed country, has no listing in that country and is listed only in one or more developed countries, that company will only be eligible for FTSE Global Equity Index Series inclusion if the country of incorporation is internationally recognized as having a low taxation status that has been approved by FTSE Russell. For companies incorporated in approved low taxation countries, FTSE Russell will normally assign the company to the developed country with the greatest liquidity. The country allocation of the FTSE Emerging Markets Index constituents may be reassessed at any time at the FTSE Russell's discretion.

***Eligible Securities***

Ineligible securities include those whose business is that of holding equity and other investments, those of Limited Liability Partnerships, Limited Partnerships, Master Limited Partnerships, Limited Liability Companies and Business Development Company, and a stapled unit if it comprises an eligible security and a non-eligible security, and convertible preference shares and loan stocks until converted. Shares that have been listed but do not form part of a company's current issued share capital, such as treasury shares and shares pending issuance to an employee scheme, will be excluded from the full market capitalization calculation.

Securities that are subject to surveillance by the stock exchanges and have been assigned to any of the following segments will not be eligible for index inclusion. Where an existing constituent is assigned to an ineligible segment, it will normally be deleted from the FTSE Emerging Markets Index at the next quarterly review and it will only be

reconsidered for index inclusion after a period of 12 months from its deletion subject to it no longer being under surveillance. For the purposes of the index eligibility, it will be treated as a new issue.

Securities that are assigned to the above segments after the review announcement date but before the FTSE Emerging Markets Index review effective date are assessed on a case-by-case basis which may generally result in scheduled FTSE Emerging Markets Index review additions, investability weight and shares in issue changes no longer being implemented at the forthcoming review.

***Trading Screens***

Existing and non-constituent securities that have not traded on 60 or more trading days during the past year (up to and including the review cut-off date), will not be eligible for index inclusion. Regular/ad hoc market holidays, and unscheduled market closures will not count towards the total; otherwise, the reason(s) for a security's non-trading will not be considered. If a security does not have a full year of trading, the 60 day period will be pro-rated according to the number of available trading days passed since its listing. Please note:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· All standard trading days will be incorporated within the calculation (Friday and Sundays as appropriate);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Ad-hoc non-standard trading days will not be incorporated within the calculation (*e.g.* ad-hoc Saturday trading will not be
considered);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Where a pro-rata calculation is necessary, the number of available trading days on the underlying market during the previous year
up to and including the review cut-off date will be used as the basis of the calculation (*e.g.* Market ABC has 253 available trading
days for the annual period to the review cut-off date; therefore the security would not be eligible if for 23.7% (60/253) or more of its
available trading days since listing, it did not trade);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· A security which has been removed from an index as a result of this screen will only be re- considered for inclusion after a period
of 12 months from its deletion. For the purposes of index eligibility, it will be treated as a new issue.

***Algorithm and Calculation Method***

The FTSE Global Equity Index Series uses actual closing mid-market or last trade prices, where available, for securities with local market quotations. Thomson Reuters real time exchange rates are used in the index calculations which are disseminated in real-time. Exchange rates used in the End of Day calculations are WM/Reuters Closing Spot Rates™, collected at 16:00 hrs London time.

The FTSE Emerging Markets Index may consist of individual securities denominated in a range of currencies, necessitating the conversion of stock prices to a common currency using the following formula:

![](image_005.jpg)

Where

![](image_006.jpg) is the U.S. dollar capital index of country j on day t

*n* is the number of index constituents

*p<sub>i,t </sub>*is the price of stock i in local currency on day t

*s<sub>i,t</sub>* is the shares in issue of stock i on day t

*f<sub>i,t </sub>*is the free float percentage of ordinary shares in issue of stock i on day t

![](image_007.jpg) is the exchange rate to U.S. dollar of stock i on day 1

The currency effect is removed by holding exchange rates constant at the previous day's level using the following formula:

![](image_008.jpg)

Where

![](image_009.jpg) is local currency exchange rate of stock i on day t

![](image_010.jpg) is the price of stock i on day t-1 adjusted for corporate actions effective on day t

The U.S. dollar index may also be derived as:

![](image_011.jpg)

Where ![](image_012.jpg) is country index j expressed in another currency (x) and ![](image_013.jpg) is the currency x to U.S. dollar exchange rate on the index base date. Note the exchange rate is expressed in units of x per dollar. Similarly, a pound sterling index may be derived as:

![](image_014.jpg)

or

![](image_015.jpg)

Where ![](image_016.jpg) is the number of U.S. dollars per pound sterling at time t.

The performance of the FTSE Emerging Markets Index on a given day is determined by calculating the percentage difference between:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the FTSE Emerging Markets Index's market capitalization as at the close of that day; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the market capitalization at the start of that day.

"Start of the day" is defined as the previous day's close adjusted for capital changes, investability weight changes, additions and deletions.

Adjustments are applied whenever capital changes take place, so that the performance of the FTSE Global Equity Index Series reflects the experience of investors. Eligible companies may be subject to adjustment for free float and multiple lines.

***Free Float and Multiple Lines Adjustments***

<u>Free Float:</u> The FTSE Global Equity Index Series is adjusted for free float and foreign ownership limits. Free float restrictions include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Shares directly owned by State, Regional, Municipal and Local governments (excluding shares held by independently managed pension
schemes for governments.)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Shares held by directors, senior executives and managers of the company, and by their family and direct relations, and by companies
with which they are affiliated.\*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Shares held within employee share plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Shares held by public companies or by non-listed subsidiaries of public companies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· All shares where the holder is subject to a lock-in clause (for the duration of that clause.)\*\*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· All shares where the holder has a stated incentive to retain the shares (*e.g.* bonus shares paid if holding is retained for
a set period of time.)\*\*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Shares held by an investor, investment company or an investment fund for strategic reasons as evidenced by specific statements to
that effect in publicly available announcements, has an employee on the board of directors of a company, has a shareholder agreement,
has successfully placed a current member to the board of directors, or has nominated a current member to the board of directors alongside
a shareholder agreement with the company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Shares that are subject to on-going contractual agreements (such as swaps) where they would ordinarily be treated as restricted.

\* For the analysis of U.S. company free float, holdings of options, warrants and convertibles will be removed from the officer and director holdings when those shares are provided in summed format within the footnotes of the SEC filings. Where FTSE Russell determines that a company is being excluded from index membership solely on the basis of the minimum float requirement, FTSE Russell will use the best available information contained in the SEC filings to determine the free float.

\*\* Free float changes resulting from the expiry of a lock-in or incentive will be implemented at the next quarterly review subject to the lock-in or incentive expiry date occurring on or prior to the share and float change information cut-off date.

Holdings that are not considered as restricted free float include portfolio holdings, nominee holdings, holdings by investment companies and ETFs. If in addition to the above restricted holdings, the company's shareholders are

subject to legal restrictions, including foreign ownership restrictions, that are more restrictive, the legal restriction will be considered a free float restriction. While shares disclosed as being held by a nominee account are typically regarded as free float, if a restricted shareholder (as described above) is identified as holding shares through a nominee account, then that portion of shares will be restricted. If a company changes its foreign ownership restriction, the change will be implemented at the subsequent quarterly review.

Free float is calculated using available published information rounded to 12 decimal places. Except where the investable market capitalization of the security exceeds 10 times the regional inclusion percentage level, securities with a free float of 5% or below are not eligible for inclusion in the FTSE Emerging Markets Index.

The FTSE Global Equity Index Series will be periodically reviewed for changes in free float.

<u>Multiple Lines:</u> Where there are multiple lines of equity capital in a company, all are included and priced separately, provided that they pass index eligibility screens in their own right and all partly-paid classes of equity are priced on a fully-paid basis if the calls are fixed and are payable at known future dates. Those where future calls are uncertain in either respect are priced on a partly-paid basis.

***Liquidity***

Each security will be tested for liquidity semi-annually in March and September by calculation of its monthly median of daily trading volume.

Liquidity will be calculated for the March review from the first business day of January to the last business day of December of the previous year and for the September review from the first business day of July of the previous year to the last business day of June. When calculating the median of daily trading volume of any security for a particular month, a minimum of five trading days in that month must exist, otherwise the month will be excluded from the test.

For each month, the daily trade total for each security is calculated as a percentage of the shares in issue for that day adjusted by the free float at the review cutoff date. These daily values are then ranked in descending order and the median is taken by selecting the value for the middle ranking day if there is an odd number of days and the mean of the middle two if there is an even number of days. Daily totals with zero trades are included in the ranking, therefore a security that fails to trade for more than half of the days in a month will have a zero median trading volume for that month. Any period of suspension will not be included in the test. For newly eligible securities where the testing period is less than 12 months, the liquidity test will be applied on a pro-rata basis.

Liquidity Thresholds:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· An existing constituent which, based on its median daily trading volume per month does not turnover at least 0.04% of its shares in
issue (after the application of any free float weightings\*) for at least eight of the twelve months prior to a full market review will
be removed from the FTSE Global Equity Index Series. If an existing constituent fails this test, then that existing constituent
will be subject to a further test whereby the last 6 months of the testing period will be assessed on a pro-rata basis. If
the existing constituent passes at least 4 out of the last 6 months (equating to 8 out of 12 months on a pro-rata basis), it will be considered
to have passed the liquidity test.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· A non-constituent which, based on its median daily trading volume per month,
does not turnover at least 0.05% of its shares in issue (after the application of any free float weightings\*) for at least ten of the
twelve months prior to a full market review will continue to be excluded from the FTSE Global Equity Index Series.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· New issues that do not have a twelve-month trading record must have a minimum three-month trading record when reviewed. They
must turnover at least 0.05% of their shares in issue (after the application of any free float weightings)\* based on their median daily
trading volume each month, on a pro-rata basis since listing. This rule will not apply to new issues added under the Fast Entry
Rule. Newly eligible securities will be treated as new issues and liquidity will be tested from the date of eligibility. Trading
records prior to this date will generally not be taken into account.

In assessing liquidity, data will be aggregated from trading volume in the country in which the company is classified by FTSE Russell and from any other trading venues, as approved by FTSE Russell, operating in a similar time zone. In the event that a company fails the liquidly test based on its underlying shares, and the company has an equivalent Depositary Receipt ("DR"), then the DR may be considered for inclusion in the FTSE Emerging Markets Index if it passes the liquidity test in its own right and is traded on an exchange within the similar regional time-zone to where the underlying shares are listed. Where the DR has been included it will remain in the FTSE Emerging Markets Index until such a time it either fails the liquidity test or the underlying share passes the liquidity test for two future consecutive reviews.

The above percentage figures may be adjusted by up to 0.01% at a market review so that, in FTSE Russell's opinion, the FTSE Emerging Markets Index better reflects the liquid investable market of the region. This discretion may only be exercised across the whole of a region and may not be applied to individual securities or countries.

\* When testing liquidity, the free float weight as at the last date in the testing period will be used for the calculation for the whole of that period.

***Periodic Review of Index Constituents***

Countries are usually reviewed semi-annually in March and September, on a region by region basis, based on data as at the close of business on the last business day of December and June (where the last business day of the month falls on a Saturday or Sunday for any individual countries, data will be taken as at close of the last business day before Saturday). Any constituent changes resulting from the periodic review will be implemented after the close of business on the third Friday (*i.e.*, effective the following Monday) of March and September. The review process is designed to reflect market movements since the previous review and to minimize turnover. As of the March 2019 semi-annual review, the different China Share classes will be reviewed as a standalone region. China A Shares that passed the March 2019 semi-annual index eligibility criteria were added to the FTSE Global Equity Index Series in June 2019, subject to them continuing to be available on the Northbound China Stock Connect Scheme Buy and Sell List.

In order to determine which companies are included in the FTSE Emerging Markets Index, first the 100% regional universe is defined by ranking all companies in each Regional Universe by their full market capitalization. Companies are then ranked by full market capitalization (companies that are capped will be ranked based on their capped market capitalization) in descending order, and the top 98% by weight of the regional universe is selected as the Index Universe. Investability weights are assigned to all companies in accordance with the free float rules, the multiple lines rule is applied, all secondary lines which fail are eliminated, and the liquidity rule is applied to all remaining eligible lines of stock. From there, each company is evaluated for inclusion in the FTSE Emerging Markets Index:

To reduce turnover, existing and potential constituents are subject to a series of 'buffer zones' to determine the cut-off points between Large, Mid and Small Cap – the buffers are detailed in the table below.

---

| | | |
|:---|:---|:---|
| | **Turnover Bands (Based on Index Universe)** | **Turnover Bands (Based on Index Universe)** |
| | **Eligible For Inclusion** | **Eligible For Exclusion** |
| Large Cap | 68% | 72% |
| Mid Cap | 86% | 92% |
| Small Cap | 98% | 101% |

---

For companies not currently in the FTSE Index:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Companies at or above 68% of the Index Universe by full market capitalization with a weight greater than 0.04% of the current respective
regional All-World Index by full market capitalization, and with a

weight greater than the inclusion percentage for the respective region by investable market capitalization, will be included in the Large Cap Index for the region under review.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Companies ranked below 68%, but within the top 86% of the Index Universe by full market capitalization with a weight greater than
0.04% of the current respective regional All-World Index by full market capitalization, and with a weight greater than the inclusion percentage
levels for the respective region by investable market capitalization, will be included in the Mid Cap Index for the region under review.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Companies ranked below the top 86%, but within the top 98% of the Index Universe by full market capitalization or have
a weight less than 0.04% of the current respective regional All-World Index by full market capitalization, and with a weight greater than
the inclusion percentage levels for the respective region by investable market capitalization will be included in the Small
Cap Index for the region under review.

For existing FTSE constituents:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Existing Large Cap constituents will remain in the Large Cap Index if they fall within the top 72% of the ranking described above.
If they are ranked between 72% and 92% of the Index Universe they will move to the Mid Cap. If they are ranked below 92% of the Index
Universe but within the top 101% of the Index Universe, they will move to the Small Cap. If they are ranked below 101% of the Index Universe
by full market capitalization or have a weight less than the exclusion percentage levels for the respective region by investable market
capitalization, they will be excluded from the FTSE Emerging Markets Index.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Existing Mid Cap constituents will move to the Large Cap if they fall within the top 68% of the ranking described above. If they are
ranked between 68% and 92% of the Index Universe they will remain in the Mid Cap. If they are ranked below 92% of the Index Universe but
within the top 101% of the Index Universe, they will move to the Small Cap. If they are ranked below 101% of the Index Universe by full
market capitalization or have a weight less than the exclusion percentage levels for the respective region by investable market capitalization,
they will be excluded from the FTSE Emerging Markets Index.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Existing Small Cap constituents will move to the Large Cap if they fall within the top 68% of the ranking described above. If they
are ranked between 68% and 86% of the Index Universe by full market capitalization and have a weight greater than 0.04% of the current
respective regional All-World Index by full market capitalization they will move to the Mid Cap. If they are ranked below 86% of the Index
Universe or have a weight less than 0.04% of the current respective regional All World Index by full market capitalization, but within
the top 101% of the Index Universe, they will remain in the Small Cap. If they are ranked below 101% of the Index Universe by full market
capitalization or have a weight less than the exclusion percentage levels for the respective region by investable market capitalization,
they will be excluded from the FTSE Emerging Markets Index.

Inclusion and exclusion percentage levels by investable market capitalization for all the regions in the FTSE Global Equity Index Series to determine additions and deletions and other changes in the FTSE Emerging Markets Index are shown below. These percentages are based from the respective regional Small Cap Index. Individual securities will be tested against the relevant regional levels.

In exceptional circumstances where FTSE Russell believes that strict adherence to the inclusion and exclusion levels listed in the above table would produce either excessive turnover at an index review, or an index that inaccurately represented different size segments, FTSE Russell reserves the right to vary the percentage levels.

***Fast Entry Rule***

Non-constituent securities may be added to the FTSE Index in between semiannual review dates if it meets either of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Large Cap inclusion level: Full market capitalization of the smallest company that falls wholly within the top 68% of the Index Universe
by full market capitalization of the respective region when ranked according to the procedure outline above under "— Periodic
Review of Index Constituents."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Mid Cap inclusion level: Full market capitalization of the smallest company that falls wholly within the top 86% of the Index Universe
by full market capitalization of the respective region when ranked according to the procedure outline above under "— Periodic
Review of Index Constituents."

A security with a free float of 5% or below must have an investable market capitalization that exceeds 10 times the regional inclusion percentage level to be eligible for fast entry. These securities will be assigned to the Large Cap index. A security with a free float exceeding 5% must meet both a full market capitalization threshold at company level and an investable market capitalization threshold at security level in order to be eligible for fast entry. The full market capitalization threshold is defined as 1.5 times the Mid Cap inclusion level above. For example, if the 86% Mid Cap inclusion level is $10 billion, the full market capitalization fast entry threshold at company level will be $10 billion multiplied by 1.5, which is $15 billion. The investable market capitalization threshold is defined as 0.5 times the Mid Cap inclusion level. For example, if the 86% Mid Cap inclusion level is $10 billion, the investable market capitalization fast entry threshold at security level will be $10 billion multiplied by 0.5, which is $5 billion.

Where a security passes both the full market capitalization and investable market capitalization test, it will be assigned to the Large Cap index subject to its full market capitalization breaching the Large Cap inclusion level above, otherwise it will be assigned to the Mid Cap index. Only shares offered at the time of the IPO will be included within the investable market capitalization calculation for the purposes of evaluating fast entry eligibility, and if eligible, the offering shares only will be included within the index calculation. When evaluating the investability weight of a potential IPO fast entry, FTSE Russell will restrict all shares that are only available to domestic retail investors. The shares that are only available to domestic retail investors will be evaluated for free float at a subsequent review. Additionally, any incentives to hold the offered shares will render those shares restricted from free float until the incentives have expired. Foreign investors are prohibited from participating in China A IPO's via the Stock Connect access route; hence China A Share IPO's will be assessed for index eligibility at the next index review, subjecting to certain meeting requirements. Shares being offered as a greenshoe (over allotment option) and locked-up shares will be excluded from the investable market capitalization calculation and excluded from the index calculation at the time of fast entry.

The fast entry level thresholds will be set at the time of the semiannual reviews in March and September using data at the last trading day in December and June. The fast entry levels thresholds will be adjusted up to February 11 or August 11 (previous trading day's data will be taken if any of these dates are on a non-trading day), respectively, to reflect the performance of the regional FTSE All Cap Equity Index Series, and will be published by FTSE Russell.

The fast entry level thresholds for each region will be set at the time of the semiannual review in March and September and will be published by FTSE Russell. In June and December the fast entry levels thresholds will be adjusted up to May 11 or November 11 (previous trading day's data will be taken if any of these dates are on a non-trading day), as appropriate, to reflect the performance of the region in the regional FTSE All Cap Equity Index Series, and an updated figure will be published by FTSE Russell.

***Changes to Constituent Companies***

Under certain circumstances, companies can be added to the list of constituent stocks outside of a review when meeting certain market capitalization thresholds. Stocks can be deleted from the list of constituents if their market capitalization or weight falls below certain levels, there exists evidence of a change in circumstance regarding investability, or the constituent stock becomes delisted or becomes bankrupt, insolvent or is liquidated. Constituents can also be deleted under certain circumstances involving delisting, suspension or relisting.

If an existing constituent is acquired for eligible shares (or a combination of eligible shares and cash) by another constituent in its own or another country, then the existing constituent is deleted on the effective date of the acquisition. The enlarged company remains a constituent of the same benchmarks within the FTSE Global Equity Index Series as the acquired company.

Mergers between a constituent and non-constituent:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Within one country: If an existing constituent is acquired for eligible shares (or a combination of eligible shares and cash) by a
quoted non-constituent in the same country, then the purchasing company is added to the same benchmarks within the FTSE Global Equity
Index Series as the acquired company on the effective date of the acquisition, if eligible in all other respects. The existing constituent
is deleted on the same date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Cross border: If an existing constituent is acquired for eligible shares (or a combination of eligible shares and cash)
by a quoted non-constituent in another country, the acquiring company will be included in its own country index on the effective date
of acquisition, providing it is eligible in all other respects. The existing constituent will be deleted on the same date.

**Corporate Actions**

FTSE Russell applies corporate actions and events to the FTSE Emerging Markets Indices on a daily basis. A company's index membership and its weight in the index can be impacted by these corporate actions and events. FTSE Russell uses a variety of public sources to determine when an event is final, including a company's press releases and regulatory filings, local exchange notifications, and official updates from other data providers. Prior to the completion of a corporate event, FTSE Russell estimates the effective date on the basis of the same above sources. As new information becomes available, FTSE Russell may revise the anticipated effective date and the terms of the corporate event, before confirming its effective date.

Depending upon the time an event is determined to be final, FTSE Russell either (1) applies the event before the open on the ex-date or (2) applies the event providing appropriate notice if it is deemed to be "actionable" for passive index managers. The impact of the event and the effective date will be communicated to clients on a regular schedule, via the daily corporate actions and events deliverables.

If FTSE Russell has confirmed the completion of a corporate event, scheduled to become effective subsequent to a rebalance or index review, the event may be implemented in conjunction with the rebalance to limit turnover, providing appropriate notice can be given.

The FTSE Emerging Markets Indices recognize a minimum two day notice requirement for "actionable" corporate event implementation such as mergers and acquisitions. This provides an appropriate window for global managers to receive a notification of intended index treatment and consequently act upon it.
