**Equity Index Descriptions**

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

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

The Dow Jones Industrial Average<sup>TM</sup> is reported by Bloomberg L.P. under the ticker symbol "INDU."

The Dow Jones Industrial Average<sup>TM</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>TM</sup> covers all industries with the exception of transportation and utilities.

The Dow Jones Industrial Average<sup>TM</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>TM</sup> is the sum of the primary exchange prices of each of the 30 component stocks included in the Dow Jones Industrial Average<sup>TM</sup> divided by a divisor. The divisor used to calculate the price-weighted average of the Dow Jones Industrial Average<sup>TM</sup> is not simply the number of component stocks; rather, the divisor is adjusted to smooth out the effects of stock splits and other corporate actions.

**Index Construction and Maintenance** 

The Dow Jones Industrial Average<sup>TM</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>TM</sup> to the market, companies that are being considered as candidates for addition to the Dow Jones Industrial Average<sup>TM</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 index universe consists of securities in the S&P 500<sup>®</sup> Index, excluding stocks classified under Global Industry Classification Standard (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>TM</sup> is price-weighted, the Averages Committee 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>TM</sup> has a price more than 10 times that of the lowest. Maintaining adequate sector representation within the Dow Jones Industrial Average<sup>TM</sup> is also a consideration in the selection process for the Dow Jones Industrial Average<sup>TM</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>TM</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 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. |
| **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** | 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). Any potential impacts on index constituents from a spin-off are evaluated by the Averages Committee on a case by case basis. The index divisor adjusts simultaneously. |
| **Ordinary dividend** | When a company pays an ordinary cash dividend, the Dow Jones Industrial Average<sup>TM</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>TM</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. |

**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 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 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 for non-components only), dividend payments in four out of five calendar years (applies for non-components only), non-negative payout ratio (applies for components and non-components), payout ratio of less than or equal to 60% (applies for non-components only) and a minimum average daily traded value over the preceding 3-months of approximately 11.11 million euros (applies for non-components). 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. 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 stock is replaced with 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 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 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 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 and 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 all component stocks.

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), 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. 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).

(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>Adjusted price = closing price – dividend announced by the company × (1 – withholding tax if applicable)<br>Divisor: decreases<br>

|:---|:---|
| (2) Split and reverse split:<br>Adjusted price = closing price × A / B<br>New weighting factor = old weighting factor × B / A<br>Divisor: unchanged | (2) Split and reverse split:<br>Adjusted price = closing price × A / B<br>New weighting factor = old weighting factor × B / A<br>Divisor: unchanged |
| (3) Rights offering:<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>For standard rights issues:<br>Adjusted price = (closing price × A + subscription price × B) / (A + B)<br>New weighting factor = old weighting factor × closing price / adjusted price<br>Divisor: unchanged | (3) Rights offering:<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>For standard rights issues:<br>Adjusted price = (closing price × A + subscription price × B) / (A + B)<br>New weighting factor = old weighting factor × closing price / adjusted price<br>Divisor: unchanged |
| (4) Stock dividend:<br>Adjusted price = closing price × A / (A + B)<br>New weighting factor = old weighting factor × (A + B) / A<br>Divisor: unchanged<br>| (5) Stock dividend (from treasury stock):<br>Adjusted only if treated as extraordinary dividend.<br>Adjusted close = close – close × B / (A + B)<br>Divisor: decreases<br>|
| (6) Stock dividend of another company:<br>Adjusted price = (closing price × A – price of other company × B) / A<br>Divisor: decreases<br>| (7) Return of capital and share consolidation:<br>Adjusted price = (closing price – capital return announced by company × (1-withholding tax)) × A / B<br>New weighting factor = old weighting factor × B / A<br>Divisor: decreases<br>|
| (8) Repurchase of shares / self-tender:<br>Adjusted price = ((price before tender × old number of shares) – (tender price × number of tendered shares)) / (old number of shares – number of tendered shares)<br>New weighting factor = old number of weighting factor × closing price / adjusted price<br>Divisor: decreases<br>| (9) Spin-off:<br>Adjusted price = (closing price × A – price of spun-off shares × B) / A<br>New weighting factor for the spin-off = weighting factor of the parent company × B / A<br>Divisor: decreases<br>|

**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 Russell has no obligation to continue to publish, and may discontinue publication of, the FTSE<sup>®</sup> 100 Index.

The FTSE<sup>®</sup> 100 Index is reported by Bloomberg L.P. under the ticker symbol "UKX."

The FTSE<sup>®</sup> 100 Index is an index calculated, published and disseminated by FTSE Russell, a wholly owned subsidiary of London Stock Exchange Group plc. The FTSE<sup>®</sup> 100 Index measures the composite price performance of the 100 largest 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.

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

The 100 stocks included in the FTSE<sup>®</sup> 100 Index (the "FTSE Underlying Stocks") were selected from a reference group of stocks trading on the LSE that were selected by excluding certain stocks that have low liquidity, public float accuracy, and reliability of prices, or size or have limited voting rights by unrestricted shareholders or foreign ownership restrictions. The FTSE Underlying Stocks were selected from this reference group by selecting 100 stocks with the largest market value. Where there are multiple lines of listed equity capital in a company, all are included and priced separately, *provided* that the secondary line's full market capitalization (*i.e.* before the application of any investability weightings) is greater than 25% of the full market capitalization of the company's principal line and the secondary line satisfies the eligibility rules and screens in its own right in all respects.

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. Companies already included in the FTSE<sup>®</sup> 100 Index in 2017 that did not meet the voting rights requirement were afforded a five-year grandfathering period to comply or they will be removed from the FTSE<sup>®</sup> 100 Index in September 2022.

The FTSE<sup>®</sup> 100 Index is overseen and reviewed quarterly in March, June, September and December 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. Each review is based on data from the close of business 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 or its issuer is subject to a takeover offer that has been declared unconditional 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.

**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.

**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.

*Defining the Equity Universe*

&nbsp;&nbsp;&nbsp;&nbsp;(i) Identifying Eligible Equity Securities: All listed equity securities, including real estate investment trusts 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;(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 Developed Markets ()"**DM** "), Emerging Markets ()"**EM** ")
or Frontier Markets ()"**FM** "). 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 Universes; 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;(i) Identifying Eligible Listings: A security may have a listing that trades in the country where it is classified (*i.e.*, a "**local listing**") and/or a listing that trades in a different country (*i.e.*, 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;(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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) 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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) 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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) 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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) 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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) 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 ()"**FOL**") 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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) 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, with the following free float-adjusted market capitalization market coverage target ranges:

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

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

&nbsp;&nbsp;&nbsp;&nbsp;(iii) Large Cap Index: 70% ± 5%

&nbsp;&nbsp;&nbsp;&nbsp;(iv) 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;(v) 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.

Treatment of Securities that Exhibit Extreme Price Increase: Additional size segment investability requirements are set for the Investable Market and the Standard Indices. For instance, securities that exhibit extreme price increase will not be eligible for addition into the Standard Index but will continue to be considered as part of the market investable equity universe. Such securities will be re-evaluated for Standard Index inclusion at the subsequent index review using Standard Index inclusion criteria, including the applicable return-based thresholds for extreme price increase. MSCI will evaluate the 5-day to 60-day excess returns, in increments of 5 days, as of the price cutoff date of the index review, for additions to the Standard Indices. Excess return is calculated as the difference between the return of a security for the relevant period and the average return of Investable Market Index constituents belonging to the same country-sector where the security is classified (in terms of country of classification and GICS<sup>®</sup> classification at the sector level). For country-sectors that have five or fewer Investable Market Index constituents, the relevant country Investable Market Index return is used instead. IPOs that do not meet the minimum length of trading requirement but meet all other criteria for Standard Index inclusion are not subject to this requirement.

*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 Developed Market or three securities in an Emerging Market, 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 Developed Market or three in that Emerging Market. At subsequent index reviews, if after the application of the index maintenance methodology a Standard Index contains less than five securities in a Developed Market or three securities in an Emerging Market, then the remaining securities are selected for inclusion by ranking such securities by descending free float-adjusted market capitalization and multiplying the free float-adjusted market capitalization of such securities by a factor of 1.5.

*Constructing and Calculating the Individual MSCI 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 Market 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 review includes 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 review includes 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 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 a RIC. More specifically, one requirement of a RIC is that, at the end of each quarter of a 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 ongoing reflection of the constraints requires an MSCI 25/50 Index to be rebalanced periodically. The MSCI 25/50 Indices are 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 an 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.

**Index Construction and Maintenance Methodology**

*Constructing and Rebalancing the MSCI 25/50 Indices*

The MSCI 25/50 Index 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;· no issuer may exceed 25% of index weight; and

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

*Minimizing weight distance from the relevant parent index.* The MSCI 25/50 Index methodology aims at minimizing the weight distance from the relevant parent index. The active risk or the tracking error of an MSCI 25/50 Index versus the relevant parent index is measured as the distance 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 any 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 the MSCI 25/50 Indices, 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.* The MSCI 25/50 Indices are 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 their parent indices.

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

In case a 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 each MSCI 25/50 Index. The constraint factor is defined as the weight in the applicable 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 remains constant between index reviews except in case of corporate events.

*Ongoing Event Related Changes.* A security added to a parent index following a corporate event is added to the relevant MSCI 25/50 Index with an estimated capped weight, without rebalancing of the 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.

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.

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

&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 the relevant 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.

**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. The Nasdaq-100 Index<sup>®</sup> is calculated, maintained and published by Nasdaq, Inc. Nasdaq, Inc. 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 reported by Bloomberg L.P. under the ticker symbol "NDX."

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. Current information regarding the market value of the Nasdaq-100 Index<sup>®</sup> is available from Nasdaq as well as numerous market information services.

The Nasdaq-100 Index<sup>®</sup> share weights of the component securities of the Nasdaq-100 Index<sup>®</sup> at any time are based upon the total shares outstanding 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 total shares outstanding 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 Nasdaq-100 Index<sup>®</sup> reporting purposes.

**Security Eligibility Criteria**

Eligible security types generally include American depositary receipts, common stocks, ordinary shares and tracking stocks. Companies organized as real estate investment trusts ("**REITs**") are not eligible for index inclusion. If the security is a depositary receipt representing a security of a non-U.S. issuer, then references to the "issuer" are references to the underlying security and the TSO is the actual depositary shares outstanding as reported by the depositary banks.

If an issuer has listed multiple security classes, all security classes are eligible, subject to meeting all other security eligibility criteria.

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. If the issuer of the security is organized under the laws of a jurisdiction outside the United States, then that security must have listed options on a registered options market in the United States or be eligible for listed-options trading on a registered options market in the United States.

The security must be classified as a non-financial company (any industry other than financials) according to the Industry Classification Benchmark. There is no market capitalization eligibility criterion. Each security must have a minimum average daily trading volume of 200,000 shares (measured over the three calendar months ending with the month that includes the reconstitution reference date).

The security must have traded for at least three full calendar months, not including the month of initial listing, on an eligible exchange, which includes Nasdaq (Nasdaq Global Select Market, Nasdaq Global Market or Nasdaq Capital Market), NYSE, NYSE American or Cboe BZX. Eligibility is determined as of the constituent selection reference date and includes that month. A security that was added to the Nasdaq-100 Index<sup>®</sup> as the result of a spinoff event will be exempt from the seasoning requirement. There is no float eligibility criterion.

The issuer of the security generally may not currently be in bankruptcy proceedings.

The issuer of the security generally may not have entered into a definitive agreement or other arrangement that would make it ineligible for index inclusion and where the transaction is imminent as determined by the Nasdaq Index Management Committee.

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

Nasdaq selects constituents once annually in December. The security eligibility criteria are applied using market data as of the end of October and TSO as of the end of November. Index reconstitutions are announced in early December and become effective after the close of trading on 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 in early March, June, September and December and become effective after the close of trading on the third Friday in March, June, September and December. A special rebalance may be conducted at any time based on the weighting restrictions described in the index rebalance procedure if it is determined to be necessary to maintain the integrity of the Nasdaq-100 Index<sup>®</sup>.

**Constituent Selection**

A reconstitution is conducted on an annual basis, at which time all eligible issuers, ranked by market capitalization, are considered for index inclusion based on the following order of criteria.

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

&nbsp;&nbsp;&nbsp;&nbsp;2. Any other issuers 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®.

&nbsp;&nbsp;&nbsp;&nbsp;3. In the event that fewer than 100 issuers pass the first two
criteria, the remaining positions will first be filled, in rank order, by issuers currently in the Nasdaq-100 Index<sup>®</sup> ranked
in positions 101-125 that were ranked in the top 100 at the previous reconstitution or replacement- or spin-off-issuers added since the
previous reconstitution.

&nbsp;&nbsp;&nbsp;&nbsp;4. In the event that fewer than 100 issuers pass the first three
criteria, the remaining positions will be filled, in rank order, by any issuers ranked in the top 100 that were not already members of
the Nasdaq-100 Index<sup>®</sup> as of the reference date.

**Constituent Weighting**

The Nasdaq-100 Index<sup>®</sup> is a modified market capitalization-weighted index.

*Quarterly Weight Adjustment*

The Nasdaq-100 Index<sup>®</sup>'s quarterly weight adjustment employs a two-stage weight adjustment scheme according to issuer- level constraints.

Nasdaq-100 Index<sup>®</sup> securities' initial weights are determined using up to two calculations of market capitalization: TSO-derived market capitalization and index share-derived market capitalization. TSO-derived market capitalization is defined as a security's last sale price times its TSO. Nasdaq-100 Index<sup>®</sup> share-derived market capitalization is defined as a security's last sale price times its updated index shares as of the prior month end. Both TSO-derived and index share-derived market capitalizations can be used to calculate TSO-derived and index share-derived initial index weights by dividing each index security's (TSO- or index share-derived) market capitalization by the aggregate (TSO- or index share-derived) market capitalization of all index securities.

When the rebalance coincides with the reconstitution, only TSO-derived initial weights are used. When the rebalance does not coincide with the reconstitution, index share-derived initial weights are used when doing so results in no weight adjustment; otherwise, TSO-derived weights are used in both stages of the weight adjustment procedure. Issuer weights are the aggregated weights of the issuers' respective index securities.

*Stage 1.* If no initial issuer weight exceeds 24%, initial weights are used as Stage 1 weights; otherwise, initial weights are adjusted so that no issuer weight may exceed 20% of the Nasdaq-100 Index<sup>®</sup>.

*Stage 2.* If the aggregate weight of the subset of issuers whose Stage 1 weights exceed 4.5% does not exceed 48%, Stage 1 weights are used as final weights; otherwise, Stage 1 weights are adjusted so that the aggregate weight of the subset of issuers whose Stage 1 weights exceed 4.5% is set to 40%.

*Annual Weight Adjustment*

The Nasdaq-100 Index<sup>®</sup>'s annual weight adjustment employs a two-stage weight adjustment scheme according to security-level constraints.Nasdaq-100 Index<sup>®</sup> securities' initial weights are determined via the quarterly weight adjustment procedure.

*Stage 1*. If no initial security weight exceeds 15%, initial weights are used as Stage 1 weights; otherwise, initial weights are adjusted so that no security weight may exceed 14% of the Nasdaq-100 Index<sup>®</sup>.

*Stage 2.* If the aggregate weight of the subset of index securities with the five largest market capitalizations is less than 40%, Stage 1 weights are used as final weights; otherwise, Stage 1 weights are adjusted so that (i) the aggregate weight of the subset of index securities with the five largest market capitalizations is set to 38.5% and (ii) no security with a market capitalization outside the largest five may have a final index weight exceeding the lesser of 4.4% or the final index weight of the index security ranked fifth by market capitalization.

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

*Deletion Policy*

If, at any time other than an index reconstitution, Nasdaq determines that an index security is ineligible for index inclusion, the index security is removed as soon as practicable.

This may include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Listing on an ineligible index exchange.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Merger, acquisition or other major corporate event that would adversely impact
the integrity of the Nasdaq-100 Index<sup>®</sup>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· If a company is organized as a REIT.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· If an index security is classified as a financial company (financials industry)
according to the ICB.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· If the issuer has an adjusted market capitalization below 0.10% of the aggregate
adjusted market capitalization of the Nasdaq-100 Index<sup>®</sup> for two consecutive month ends.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· If a security that was added to the Nasdaq-100 Index<sup>®</sup> as the
result of a spin-off event has an adjusted market capitalization below 0.10% of the aggregate adjusted market capitalization of the Nasdaq-100
Index<sup>®</sup> at the end of its second day of regular way trading as a Nasdaq-100 Index<sup>®</sup> member.

In the case of mergers and acquisitions, the effective date for the removal of an index issuer or security will be largely event-based, with the goal to remove the issuer or security as soon as completion of the acquisition or merger has been deemed highly probable. Notable events include, but are not limited to, completion of various regulatory reviews, the conclusion of material lawsuits and/or shareholder and board approvals.

If at the time of the removal of the index issuer or security there is not sufficient time to provide advance notification of the replacement issuer or security so that both the removal and replacement can be effective on the same day, the index issuer or security being removed will be retained and persisted in the index calculations at its last sale price until the effective date of the replacement issuer or security's entry to the Nasdaq-100 Index<sup>®</sup>.

Securities that are added as a result of a spin-off may be deleted as soon as practicable after being added to the Nasdaq-100 Index<sup>®</sup>. This may occur when Nasdaq determines that a security is ineligible for inclusion because of reasons such as ineligible exchange, security type, industry or adjusted market capitalization. Securities that are added as a result of a spin-off may be maintained in the Nasdaq-100 Index<sup>®</sup> until a later date and then removed, for example, if a spin-off security has liquidity characteristics that diverge materially from the security eligibility criteria and could affect the integrity of the Nasdaq-100 Index<sup>®</sup>.

*Replacement Policy*

Securities may be added to the Nasdaq-100 Index<sup>®</sup> outside of the index reconstitution when there is a deletion. The index security (or all index securities under the same issuer, if appropriate) is replaced as soon as practicable if the issuer in its entirety is being deleted from the Nasdaq-100 Index<sup>®</sup>. The issuer with the largest market capitalization as of the prior month end which is not in the Nasdaq-100 Index<sup>®</sup> will replace the deleted issuer. Issuers that are added as a result of a spin-off are not replaced until after they have been included in a reconstitution.

For pending deletions set to occur soon after an index reconstitution and/or index rebalance effective date, Nasdaq may decide to remove the index security from the Nasdaq-100 Index<sup>®</sup> in conjunction with the index reconstitution and/or index rebalance effective date.

*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 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 Index<sup>®</sup> constituents, statistics comparing the composition of the Nasdaq-100 Index<sup>®</sup> to the market, companies that are being considered as candidates for addition to the Nasdaq-100 Index<sup>®</sup> and any significant market events.

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

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

The Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> began on February 22, 2006 at a base value of 1,000.00. The Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> is reported by Bloomberg, L.P. under the ticker symbol "NDXT."

The Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> is an equal weighted, price-return index based on technology companies included in the Nasdaq-100 Index<sup>®</sup>.

**Index Calculation**

The Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> is an equal weighted, price return index.

**Eligibility Criteria**

The Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> contains securities of the Nasdaq-100 Index<sup>®</sup> which are classified as Technology according to the Industry Classification Benchmark ("ICB"). The eligibility for the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> is determined in a 2-step process and the security has to meet both criteria in order to become eligible for the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup>. For additional information about the Nasdaq-100 Index<sup>®</sup>, including the methodology for inclusion in the Nasdaq-100 Index<sup>®</sup>, see "Equity Index Description — The Nasdaq-100 Index<sup>®</sup>" in this underlying supplement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The security must be part of the Nasdaq-100 Index<sup>®</sup>, which includes 100 of the largest domestic and international non-financial companies listed on the Nasdaq.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. The company must be classified as a Technology Company (any company classified under the Technology Industry) according to the Industry Classification Benchmark (ICB), a product of FTSE International Limited that is used under license.

**Index Maintenance**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. If a component of the Nasdaq-100<sup>®</sup> Index that is classified as Technology according to ICB is removed from the Nasdaq-100<sup>®</sup> Index, it is also removed from the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup>. As such, if the replacement company being added to the Nasdaq-100<sup>®</sup> Index is classified as Technology according to ICB, it is added to the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> and will assume the weight of the removed company on the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> effective date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. If a component of the Nasdaq-100<sup>®</sup> Index that is not classified as Technology according to ICB is removed and the replacement company being added to the Nasdaq-100<sup>®</sup> Index is classified as Technology according to ICB, the replacement company is added to the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> at the next quarterly rebalancing; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. If a component of the Nasdaq-100<sup>®</sup> Index that is classified as Technology according to ICB is removed from the Nasdaq-100<sup>®</sup> Index and the replacement company being added to the Nasdaq-100<sup>®</sup> Index is not classified as Technology according to ICB, the company is removed from the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> and the divisor of the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> is adjusted to ensure index continuity.

*Deletion policy.* If a component of the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> is removed from the Nasdaq-100 Index for any reason, it is also removed from the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> at the same time.

*Additions policy*. If a security is added to the Nasdaq-100 Index for any reason, it may be added to the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> at the same time.

*Corporate actions*. In the interim periods between scheduled index reconstitution and rebalance events, individual Index securities may be the subject to a variety of corporate actions and events that require maintenance and adjustments to the Index. In certain cases, corporate actions and events are handled according to the weighting scheme or other index construction techniques employed.

*Index share adjustments.* Other than as a direct result of corporate actions, the index does not normally experience share adjustments between scheduled index rebalance and reconstitution events.

**Index Rebalancing**

The Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> follows the same reconstitution and rebalance schedule as the Nasdaq-100 Index. The Index rebalance uses the Last Sale Prices as of the close of trading on the third Friday in March, June, September and December.

*Constituent weighting.* The Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup> is rebalanced quarterly such that all issuers within the Index are assigned an equal Index market value. For issuers represented by multiple securities, those issuers' Index market values are equally apportioned across their respective Index Securities.

Index Shares are calculated by dividing each Index Security's resulting Index market value by its Last Sale Price.

In administering the Nasdaq-100<sup>®</sup> Technology Sector Index<sup>SM</sup>, Nasdaq, Inc. will exercise reasonable discretion as it deems appropriate to ensure index continuity.

**The Nikkei 225 Index**

All information contained in this underlying supplement regarding the Nikkei 225 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, Nikkei Inc. The Nikkei 225 Index is calculated, maintained and published by Nikkei Inc. Nikkei Inc. has no obligation to continue to publish, and may discontinue the publication of, the Nikkei 225 Index. The Nikkei 225 Index is reported by Bloomberg L.P. under the ticker symbol "NKY."

The Nikkei 225 Index is a stock index that measures the composite price performance of selected Japanese stocks. The Nikkei 225 Index is currently based on 225 underlying stocks (the "**Nikkei Underlying Stocks**") trading on the Tokyo Stock Exchange ("**TSE**") representing a broad cross-section of Japanese industries. Non-ordinary shares, such as shares of ETFs, REITs, preferred stock or other preferred securities or tracking stocks, are excluded from the Nikkei 225 Index.

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 annually (the "**periodic review**") in accordance with the following rules with a base date at the end of July, and results of the review are applied on the first trading day in October. Results of the review become effective on the first trading day of October, 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 volume 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 C ommunications;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;· Materials — Mining, Textiles & Apparel, Pulp & Paper, 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.

A Nikkei Underlying Stock may be delisted when it establishes a parent company through a share transfer or becomes a subsidiary of an unlisted company through a share exchange. If a new parent company is deemed to be succeeding the business of the delisted company, such new parent company may become a Nikkei Underlying Stock if it becomes listed. In such case, during the period between the delisting of the original company and the listing of the new succeeding company, the Nikkei 225 Index may be calculated with fewer than 225 Nikkei Underlying Stocks.

**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**"), (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 5 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 annually on the base date at the end of July.

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 PAFr 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.

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 May (except that initial public offerings ("**IPOs**") are 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.

&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 5.5% or less 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, installment
receipts and trust receipts.

&nbsp;&nbsp;&nbsp;&nbsp;· *Minimum Voting Rights.* As of August 2017, more than 5% of a company's
voting rights (aggregated across all of its equity securities, including, where identifiable, those that are not listed or trading) must
be in the hands of unrestricted shareholders. Existing constituents have a 5 year grandfathering period to comply or they will be removed
from each applicable Russell Index at the June 2023 reconstitution. 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 May (except that IPOs are 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 May 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 reevaluated 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. The following types of shares are removed from total market capitalization to arrive at free float or available market capitalization, based on information recorded in SEC corporate filings: officers' and directors' holdings, private holdings exceeding 10% of shares outstanding, institutional holdings exceeding 30% of shares outstanding, shares held by publicly listed companies, shares held by an Employee Stock Ownership Plan or a Leveraged Employee Stock Ownership Plan; shares locked up during an IPO; direct government holdings; and indirect government holdings exceeding 10% of shares outstanding.

Reconstitution occurs on the fourth Friday in June. A full calendar for reconstitution is published each spring, with such constitution 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 cumulativw share changes greater than 1%, cumulative
free float changes greater than 1%, for constituents with a free float of greater than 5% but less than or equal to15% 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, 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;· *Eligible Securities*. Common and equity preferred stocks (which are
not of a fixed income nature) are eligible for inclusion in the S&P/ASX 200 Index. Hybrid stocks, such as convertible stock, bonds,
warrants and preferred stock that provide a guaranteed fixed return, are not eligible. Listed investment companies that invest in a portfolio
of securities are not eligible. 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 six months. The ASX stock price history (last
six 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_042.gif)

Where:

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

&nbsp;&nbsp;&nbsp;&nbsp;· Market Liquidity is determined 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 to ensure adequate market capitalization and liquidity. Quarterly rebalancing changes take effect after the market close on the third Friday of March, June, September and December.

*Buffers.* In order to limit the level of index turnover, eligible non-constituent securities will generally only be considered for index inclusion once a current constituent stock is excluded due to a sufficiently low rank and/or liquidity, based on the float-adjusted market capitalization. Potential index inclusions and exclusions need to satisfy a buffer requirement in terms of the rank of the stock relative to the S&P/ASX 200 Index. The following buffer aims to limit the level of index turnover that may take place at each quarterly rebalancing, maximizing the efficiency and limiting the cost associated with holding the index portfolio.

---

| |
|:---|
| **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 by-pass these rules when circumstances warrant.

*Initial Public Offerings (IPOs).* An initial public offering 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.

*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. All constituents in the S&P/ASX 200 Index are assigned an IWF. A company must have a minimum IWF of 0.3 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 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 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 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' 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.

**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;1. be a member of the S&P TM Index;

&nbsp;&nbsp;&nbsp;&nbsp;2. 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;3. meet one of the following float-adjusted market capitalization and float-adjusted liquidity ratio requirements:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. be a current constituent, have a float-adjusted market capitalization greater than or equal to US$300 million, and have a float-adjusted
liquidity ratio greater than or equal to 50%;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. have a float-adjusted market capitalization greater than or equal to US$500 million and a float-adjusted liquidity ratio greater
than or equal to 90%; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. have a float-adjusted market capitalization greater than or equal to US$400 million and a float-adjusted liquidity ratio 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 float-adjusted market capitalization must be above $2 billion and its float-adjusted liquidity ratio must be above 100%, and existing index constituents of the S&P<sup>®</sup> Banks Select Industry Index are removed at the quarterly rebalancing date if either their float-adjusted market capitalization falls below $1 billion or their float-adjusted liquidity ratio 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 process established by S&P Dow Jones. Additionally, minimum float-adjusted market capitalization 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.* The liquidity measurement used is a float-adjusted liquidity ratio (FALR), defined as the annual dollar value traded divided by the float-adjusted market capitalization, is used measure liquidity. Using composite pricing and consolidated volume (excluding dark pools) across all venues (including historical values), 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 float adjusted market capitalization. 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.

*Multiple Share Classes.* Some companies in the S&P TM Index 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_043.gif)

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, companies are initially equally weighted using closing prices as of the second Friday of the last month of the quarter as the reference price. Adjustments are then made to ensure that there are no individual constituents whose weight in the relevant Select Industry Index exceeds the value that can be traded in a single day for a given theoretical portfolio value ranging from U.S. $500 million to U.S. $2,000 million (the "**Theoretical Portfolio Value**"). Theoretical Portfolio Values are determined and reviewed annually by an S&P Dow Jones' index committee (the "**Index Committee**"). Any updates to Theoretical Portfolio Values are made at the discretion of the Index Committee and announced to the clients with ample lead time.

S&P Dow Jones calculates a maximum basket liquidity weight for each constituent in the Select Industry Indices using the ratio of its three-month median daily value traded to the Theoretical Portfolio Value. Each constituent's weight in the relevant Select Industry Index is then, compared to its maximum basket liquidity weight and is set to the lesser of its maximum basket liquidity weight or its initial equal weight. All excess weight is redistributed across the relevant Select Industry Index to the uncapped stocks. If necessary, a final adjustment is made to ensure that no stock in a Select Industry Index has a weight greater than 4.5%. This step of the iterative weighting process may force the weight of those stocks limited to their maximum basket liquidity weight to exceed that weight. In such cases, S&P Dow Jones will make no further adjustments. If any of the Select Industry Indices contain exactly 22 stocks as of the rebalancing effective date, the relevant Select Industry Index is equally weighted without basket liquidity constraints.

**Maintenance of the** **Select Industry Indices**

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 second Friday of the rebalancing month are used for setting index weights. The Index Committee may change the date of a given rebalancing for reasons including market holidays occurring on or around the scheduled rebalancing date. Any such change will be announced by S&P Dow Jones with proper advance notice where possible.

The table below summarizes the treatment of certain corporate actions.

---

| | |
|:---|:---|
| **Corporate Action** | **Treatment** |
| **Company addition/deletion** | <u>Addition Only</u><br>Stocks are added between rebalancings only if a deletion in the relevant Select Industry Index causes the constituent count to fall below 22. In those cases, each stock deletion is accompanied with a stock addition. A new stock is added to that Select Industry Index at the weight of the deleted stock.<br><u>Deletion Only</u><br>A stock is deleted from the relevant Select Industry Index if dropped from the S&P TM Index. If a deletion causes the number of stocks in the relevant Select Industry Index to fall below 22, each stock deletion is accompanied with a corresponding stock addition. The weights of all stocks in that Select Industry Index will proportionately change, due to the absolute change in the number of index constituents. Relative weights will stay the same. The index divisor will change due to the net change in the market capitalization of that Select Industry Index.<br>|

---

---

| | |
|:---|:---|
| **Corporate Action** | **Treatment** |
| **Change in shares outstanding** | Shares outstanding changes are offset by an 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. |
| **Spin-off** | In the case of spin-offs, the Select Industry Indices will follow the S&P TM Index's treatment of the action. In general, both the parent and spin-off company will 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 the S&P TM Index, the weight of the spun-off company is added back to the parent stock's weight after at least one day of trading. |
| **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. |
| **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. |

---

In the case of mergers involving two index constituents, the merged entity remains in the relevant Select Industry Index provided it satisfies the eligibility criteria. If the merged entity qualifies for inclusion in the relevant Select Industry Index, 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.

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

**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' 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.

&nbsp;&nbsp;&nbsp;&nbsp;3. If any company has an FMC weight greater than 24%, the company's weight is capped at 23%, which allows for a 2% buffer. This
buffer is meant to mitigate against any company exceeding 25% as of the quarter-end diversification requirement date.

&nbsp;&nbsp;&nbsp;&nbsp;4. All excess weight is proportionally redistributed to all uncapped companies within the relevant Select Sector Index.

&nbsp;&nbsp;&nbsp;&nbsp;5. After this redistribution, if the FMC weight of any other company then breaches 23%, the process is repeated iteratively until no
company breaches the 23% weight cap.

&nbsp;&nbsp;&nbsp;&nbsp;6. 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;7. If the rule in paragraph 6 is breached, all companies are ranked in descending order of their FMC weights. The first company that
causes the 50% limit to be breached has its weight reduced to 4.5%.

&nbsp;&nbsp;&nbsp;&nbsp;8. This excess weight is proportionally redistributed to all companies with weights below 4.5%. This is repeated iteratively until paragraph
6 is satisfied.

&nbsp;&nbsp;&nbsp;&nbsp;9. Index share amounts are assigned 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.

&nbsp;&nbsp;&nbsp;&nbsp;10. If, on the second to last business day of March, June, September or December, a company has a weight greater than 24% or the sum of
the companies with weights greater than 4.8% exceeds 50%, a secondary rebalancing will be triggered with the rebalancing effective date
being after the close of the last business day of the month. This secondary rebalancing will use the closing prices as of the second to
last business day of March, June, September or December, and membership, shares outstanding and IWFs as of the rebalancing effective date.

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 its 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.

**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.

**The S&P U.S. Indices**

All information contained in this underlying supplement regarding the S&P 500<sup>®</sup> Index, the S&P MidCap 400<sup>®</sup> Index and the S&P SmallCap 600<sup>®</sup> Index (each, an "**S&P U.S. Index**" and collectively, the "**S&P U.S. 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, S&P Dow Jones Indices LLC ("**S&P Dow Jones**"). The S&P U.S. Indices are 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, any of the S&P U.S. Indices.

**The S&P 500<sup>®</sup> Index**

The S&P 500<sup>®</sup> Index consists of stocks of 500 companies selected to provide a performance benchmark for the U.S. equity markets. The S&P 500<sup>®</sup> Index is reported by Bloomberg L.P. under the ticker symbol "SPX."

**The S&P MidCap 400<sup>®</sup> Index**

The S&P MidCap 400<sup>®</sup> Index consists of stocks of 400 companies selected to provide a performance benchmark for the medium market capitalization segment of the U.S. equity markets. The S&P MidCap 400<sup>®</sup> Index is reported by Bloomberg L.P. under the ticker symbol "MID."

**The S&P SmallCap 600<sup>®</sup> Index**

The S&P SmallCap 600<sup>®</sup> Index consists of stocks of 600 companies selected to provide a performance benchmark for the small market capitalization segment in the U.S. equity markets. The S&P SmallCap 600<sup>®</sup> Index is reported by Bloomberg L.P. under the ticker symbol "SML."

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

Additions to the S&P U.S. Indices are evaluated based as follows:

&nbsp;&nbsp;&nbsp;&nbsp;· *Domicile.* The company should be a U.S. company, meaning a company
that has the following characteristics:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
company files 10-K annual reports;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the U.S. portion of fixed assets and revenues constitutes a plurality of
the total, but need not exceed 50%. When these factors are in conflict, fixed assets determine plurality. Revenue determines plurality
when there is incomplete asset information. Geographic information for revenue and fixed asset allocations are determined by the company
as reported in its annual filings. If this criteria is not met or is ambiguous, S&P Dow Jones may still deem the company to be a U.S.
company for index purposes if its primary listing, headquarters and incorporation are all in the United States and/or "a domicile
of convenience" (Bermuda, Channel Islands, Gibraltar, islands in the Caribbean, Isle of Man, Luxembourg, Liberia or Panama); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the primary listing is on an eligible U.S. exchange as described below.

In situations where the only factor suggesting that a company is not a U.S. company is its tax registration in a "domicile of convenience" or another location chosen for tax-related reasons, S&P Dow Jones normally determines that the company is still a U.S. company. The final determination of domicile eligibility is made by the S&P Dow Jones' U.S. Index Committee.

&nbsp;&nbsp;&nbsp;&nbsp;· *Exchange Listing.* A primary listing on one of the following U.S. exchanges
is required: New York Stock Exchange, NYSE Arca, NYSE American, Nasdaq Global Select Market, Nasdaq Select Market, Nasdaq Capital Market,
Cboe BZX, Cboe BYX, Cboe EDGA or Cboe EDGX exchanges. Ineligible exchanges include the OTC Bulletin Board and Pink Sheets.

&nbsp;&nbsp;&nbsp;&nbsp;· *Organizational Structure and Share Type*. Eligible organizational structures
and share types are corporations (including equity and mortgage 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 purposes acquisition
companies, tracking stocks, preferred and convertible preferred stock, unit trusts, equity warrants, convertible bonds, investment trusts,
rights and American Depositary Receipts.

As of July 2017, the securities of companies with multiple share class structures (including companies with listed and unlisted share classes) are no longer eligible to be added to the S&P U.S. Indices, but securities already included in an S&P U.S. Index have been grandfathered and are not affected by this change.

&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. For spin-offs, S&P U.S. Index membership eligibility is determined using
when-issued prices, if available.

&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 consolidated volume
(excluding dark pools) across all venues (including historical values), 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**") or spin-offs 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. 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 open of trading on the day 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 1.0 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.* The sum of the most recent four consecutive quarters'
Generally Accepted Accounting Principles ()"**GAAP**") earnings (net income excluding discontinued operations) should be
positive as should the most recent quarter. For equity REITs, financial viability is based on GAAP earnings 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.

&nbsp;&nbsp;&nbsp;&nbsp;· *Sector Classification.* The company is evaluated for its contribution
to sector balance maintenance, as measured by a comparison of each Global Industry Classification Standard sector's weight in the
relevant S&P U.S. Index with its weight in the S&P Total Market Index, in the relevant market capitalization range. The S&P
Total Market Index is a float-adjusted market capitalization-weighted index designed to track the broad U.S. equity market, including
large-, mid-, small- and micro-cap stocks.

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 to an S&P U.S. Index.

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.

Removals from the S&P U.S. Indices are evaluated based as follows:

&nbsp;&nbsp;&nbsp;&nbsp;· *Companies that are involved in mergers, acquisitions or significant restructuring such that they no longer meet the eligibility criteria.* Companies delisted as a result of merger, acquisition or other corporate action
are 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 an S&P U.S. Index until trading resumes, at the discretion of S&P Dow
Jone's U.S. index committee. If a stock is moved to the pink sheets or the OTC Bulletin Board, the stock is removed.

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 index removal date before being screened for the eligibility criteria.

&nbsp;&nbsp;&nbsp;&nbsp;· *Companies that substantially violate one or more of the addition criteria.* S&P Dow Jones believes turnover in index membership should be avoided when possible. At times, a stock may appear to temporarily
violate one or more of the addition criteria. However, the addition criteria are for addition to the S&P U.S. Indices, 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.

**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 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 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 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.

*Quarterly Update.* Share counts are updated to the latest publicly available filings on a quarterly basis. IWF changes will only be made at the quarterly review if the change represents at least 5% of total current shares outstanding and is related to a single corporate action that did not qualify for the accelerated implementation rule, regardless of whether there is an associated share change.

*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.

*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.

The table below summarizes the treatment of certain corporate actions.

---

| | |
|:---|:---|
| **Corporate Action** | **Treatment** |
| **Company 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. |
| **Change in shares 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. |

| | |
|:---|:---|
| **Corporate Action** | **Treatment** |
| **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. |
| **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. |

**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: 8985 or 8995) 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 is based on the country of incorporation, the primary listing and the country with the largest trading volume. 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; retail; 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 financial 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. The banks supersector tracks companies providing a broad range of financial services, including retail banking, loans and money transmissions. The euro price return version of the EURO STOXX<sup>®</sup> Banks Index is reported by Bloomberg L.P. under the ticker symbol "SX7E."

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. 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. In addition, the selection list for the STOXX<sup>®</sup> Europe 50 Index includes only the top 60% of the free-float market capitalization of each of the 20 STOXX<sup>®</sup> Europe 600 Supersector indices and all current STOXX<sup>®</sup> Europe 50 Index component stocks. 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 includes the top 60% of the free-float market capitalization of each of the 20 EURO STOXX<sup>®</sup> Supersector indices and all current EURO STOXX<sup>®</sup> 50 Index component stocks. 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. 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 are replaced and non-component stocks that rank 25 or above are added.

In addition, changes to country classification and listing 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 factors for each component stock used to calculate each STOXX Benchmark Index are reviewed, calculated and implemented on a quarterly basis and are 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 = free-float market capitalization of the relevant STOXX Benchmark Index <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 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. 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).

**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 reported by Bloomberg L.P. under the ticker symbol "SMI."

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.

**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 to be 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 implemented after a notification period of five trading days. The adjusted cap factors are implemented after a notification period of generally five 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 planneddelisting, 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 publication of, the TOPIX<sup>®</sup> Index.

The TOPIX® 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 at January 4, 1968, which was reset at 1,000 onApril 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 and Maintenance of the TOPIX<sup>®</sup> Index**

The TOPIX<sup>®</sup> Index is a free float-adjusted market capitalization-weighted index of 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. Japanese stocks admitted to the TSE were previously assigned to one of the First Section, the Second Section or the Mothers. Stocks listed on the First Section were typically limited to larger, longer established and more actively traded issues, stocks listed on the Second Section were typically limited to mid-sized companies and stocks listed on the Mothers were typically limited to high-growth start-up companies. Stocks that were components of the TOPIX<sup>®</sup> Index as of April 1, 2022 continue to be included after the market restructuring, regardless of their new market segment. However, component stocks with tradeable share market capitalization of under JPY 10 billion are designated as "phased weighting reduction constituents," and their weighting will be gradually reduced in ten stages on the last business day of each quarter beginning in October 2022 and ending in January 2025. Subject to a re-evaluation after the fourth stage, they will be removed from the TOPIX<sup>®</sup> Index on the last business day of January 2025.

During the transition period, additions to the component stocks can occur (1) through the initial listing of a company on or transfer to the Prime Market, with such changes taking effect on the last business day of the month after such initial listing; (2) through the initial listing of a new company resulting from a corporate consolidation that results in an index constituent being delisted, with such changes taking effect on the new listing date; or (3) through the delisting of an index constituent due to a merger with a surviving stock that is not an index constituent, with such changes taking effect on the delisting date. In addition, a company removed from the Index due to its designation as a "Securities on Alert" that has that designation canceled as of the last business day of August 2023 can be added if it meets tradeable share market capitalization and annual traded value ratio requirements, with such changes taking effect on the last business day of October 2023.

Deletions of constituents can occur due to (1) de-listing, resulting from a corporate consolidation, when the surviving company re-lists with the TSE, with such changes taking effect on the initial listing date of the new company (normally two business days after the delisting date); (2) de-listing of a company for reasons other than those stated above, with such changes taking effect on the de-listing date; or (3) designation of stocks to be de-listed, with such changes taking effect four business days after such designation. Any component stock designated as a "Security on Alert" as of April 4, 2022 was removed from the TOPIX<sup>®</sup> Index as of the last business day of April 2022.

Rules for addition of component stocks after January 31, 2025 will be determined following the transition period.

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

The TOPIX<sup>®</sup> Index is calculated using market capitalization weighting, with the market price of each component stock multiplied by the number of shares listed, as adjusted by multiplying by a free float weight ("**FFW**") that incorporates both a liquidity factor (to take into account only the listed shares deemed to be available for trading in the market) and a transition factor (in the case of a component stock identified for phased weighting reduction as described above). The upper weighting limit for any one component stock is 10%. The JPXI amended its free-float weight calculation methodology as of April 4, 2022, with changes to any component's FFW phased in over three months.

The TOPIX<sup>®</sup> Index is not expressed in Japanese 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 number of free float-adjusted common shares listed on the TSE at the same instance) (as adjusted by multiplying the FFW) (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 × 100 <br> Base Market Value

The number of free float-adjusted shares at the time of the index calculation is the number of common shares listed on the TSE multiplied by the free float weight. The free float weight is the percentage of listed shares deemed to be available for trading in the market and is calculated by the JPXI for each listed company for purposes of index calculation. The free float weight is determined by estimating the number of non-free float shares on the basis of published materials such as securities reports. In determining the free float weight, the JPXI deems the following shares as non-free float shares: shares held by the top 10 major shareholders (subject to certain exceptions), treasury stocks (including certain cross-shareholdings), shares held by board members of the relevant company, equity securities held for investment purposes other than pure investment and other shares JPXI deems not available for trading in the market. The free float weight is equal to 1 minus the number of non-free float shares divided by the number of listed shares. In the case of some companies with low liquidity, the JPXI may adjust their free float downwards by applying a "liquidity factor."

The free float weight assigned to each listed company is reviewed annually, with timings that vary according to the earnings release date of each such listed company. Free float weights may also be subject to extraordinary review at JPXI's discretion in the case of certain corporate actions (e.g., allocation of new shares, conversion of preferred shares or exercise of subscription warrants, spin-offs, mergers, stock swaps, take-overs) and for other reasons the JPXI believes appropriate.

In order to maintain continuity, the Base Market Value is adjusted from time to time to ensure that it reflects only price movements resulting from auction market activity, and to eliminate the effects of other factors and prevent any instantaneous change or discontinuity in the level of the TOPIX<sup>®</sup> Index. Such factors include, without limitation: new listings, delistings, new share issues either through public offerings or through rights offerings to shareholders (limited to cases where the allotted subscription warrant securities are listed) and issuance of shares as a consequence of exercise of convertible bonds or warrants.

The formula for the adjustment is as follows:

---

| | | |
|:---|:---|:---|
| Free float-adjusted Market Value on business day before adjustment date | = | (Free float-adjusted Market Value on business day before adjustment date ± Adjustment Amount) |
| Base Market Value before adjustment |  | 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,

---

| | | |
|:---|:---|:---|
| New Base Market Value | = | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Old Base Market Value ×<br> (Free float-adjusted Market Value on business day before adjustment date ± Adjustment Amount) |
| New Base Market Value | = | Free float-adjusted Market Value on business day before adjustment date |

---

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 or decreases in capital without compensation, which theoretically do not affect market capitalization.

**Commodity Index Descriptions**

**The Bloomberg Commodity Indices**

**General**

All information contained in this underlying supplement regarding the Bloomberg Commodity Index<sup>SM</sup>, its single-commodity sub-indices and the forward-month version of the Bloomberg Commodity Index<sup>SM</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, UBS Securities LLC (collectively with its affiliates, "UBS") and Bloomberg Index Services Limited ("BISL" and, collectively with its affiliates, "Bloomberg"). UBS and Bloomberg are not involved in the offer of the securities in any way and have no obligation to consider your interests as a holder of the securities. UBS and Bloomberg have no obligation to continue to publish, and may discontinue publication of, the Bloomberg Commodity Indices at any time in their sole discretion.

In 2014, Bloomberg became responsible for the governance, calculation, distribution and licensing of the Bloomberg Commodity Indices. The Dow Jones-UBS Commodity Index<sup>SM</sup> was renamed to the Bloomberg Commodity Index<sup>SM</sup> and the ticker changed from "DJUBS" to "BCOM." UBS and its licensors have maintained their ownership, but BISL calculates, administers and publishes the Bloomberg Commodity Indices on behalf of UBS. Material changes or amendments to the index methodology are subject to approval by the Product, Risk & Operations Committee (the "PROC") in consultation, if practical, with UBS, except during periods of extraordinary circumstances, such as during a market emergency.

**Overview**

The Bloomberg Commodity Index<sup>SM</sup> was introduced in July of 1998 to provide an economically rational, diversified, stable and liquid benchmark for commodities as an asset class. The Bloomberg Commodity Index<sup>SM</sup> currently is composed of the prices of twenty-three 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, please see "The Commodity Futures Markets" below. The commodities included in the Bloomberg Commodity Index<sup>SM</sup> for 2022 are as follows: aluminum, coffee, copper, corn, cotton, crude oil, gold, 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, hard red winter wheat ("HRW wheat"), ultra-low-sulfur diesel ("ULS diesel") 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<sup>SM</sup> 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<sup>SM</sup> follow the methodology of the Bloomberg Commodity Index<sup>SM</sup>, 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<sup>SM</sup> 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<sup>SM</sup>, the ticker symbol will be provided in the relevant terms supplement.

BISL also publishes forward-month versions of the Bloomberg Commodity Index<sup>SM</sup> and its single-commodity sub-indices that trades longer-dated commodity futures contracts. The Bloomberg Commodity Index 3 Month Forward<sup>SM</sup> follows the methodology of the Bloomberg Commodity Index<sup>SM</sup>, 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<sup>SM</sup>, such that the delivery months for the reference contracts are later than those of the corresponding reference contracts used for the Bloomberg Commodity Index<sup>SM</sup>. 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<sup>SM</sup> follow the methodology of the Bloomberg Commodity Index<sup>SM</sup>, 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<sup>SM</sup>, 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<sup>SM</sup> 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<sup>SM</sup>, the ticker symbol will be provided in the relevant terms 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 terms supplement.

UBS and its affiliates actively trade futures contracts and options on futures contracts on the commodities that underlie the Bloomberg Commodity Index<sup>SM</sup>, as well as commodities, including commodities included in the Bloomberg Commodity Index<sup>SM</sup>.

**Benchmark Governance**

BISL uses two primary committees to provide overall governance and effective oversight of its administration activities: the PROC and the Benchmark Oversight Committee (the "BOC").

The PROC provides direct governance and is responsible for controls over the creation, design, production and dissemination of benchmark indices, strategy indices and fixings administered by Bloomberg, including the Bloomberg Commodity Indices. The PROC is composed of Bloomberg personnel with experience or relevant expertise in relation to financial benchmarks. Meetings are attended by internal Bloomberg legal and compliance personnel. Nominations and removals are subject to review by the BOC, discussed below.

The oversight function is provided by the BOC. The BOC is independent of the PROC and is responsible for reviewing and challenging the activities carried out by the PROC. In carrying out its oversight duties, the BOC receives reports of management information both from the PROC as well as internal Bloomberg legal and compliance personnel engaged in second level controls.

On a quarterly basis, the PROC reports to the BOC on governance matters, including but not limited to client complaints, the launch of new benchmarks, operational incidents (including errors & restatements), major announcements and material changes concerning the benchmarks, the results of any reviews of the benchmarks (internal or external) and material stakeholder engagements.

*Internal and External Reviews*

BISL's index administration is also subject to Bloomberg's compliance function, which periodically reviews various aspects of its businesses in order to determine whether it is adhering to applicable policies and procedures, and assess whether applicable controls are functioning properly.

In addition, Bloomberg may from time to time appoint an independent external auditor with appropriate experience and capability to review adherence to benchmark regulation. The frequency of such external reviews will depend on the size and complexity of the operations and the breadth and depth of the index use by stakeholders.

*Conflicts of Interest*

BISL may exercise discretion in making certain determinations, calculations and corrections with respect to the Bloomberg Commodity Indices from time to time. In making those determinations, calculations and corrections, BISL has no obligation to take the needs of UBS into consideration. Also, neither BISL nor UBS has any obligation to take the needs of any holders of financial products based on or tracking the Bloomberg Commodity Indices (with respect to the Bloomberg Commodity Indices, "Index Products" and the holder of these products, "Index Product Investors") into consideration at any time.

BISL is committed to avoiding and, where necessary, managing actual or potential conflicts of interest in its decision-making process and has established a Conflicts of Interest Policy to minimize or resolve actual or potential conflicts of interest.

BISL does not create, trade or market Index Products.

UBS and its subsidiaries may each face conflicts between the roles it performs in respect of the Bloomberg Commodity Index<sup>SM</sup> and its own interests. In particular, in its other businesses, UBS may have, or enter into transactions to create, a physical, economic or other interest (including an adverse and/or short interest, as the case may be) in the Bloomberg Commodity Index<sup>SM</sup>, any Index Product, any component of the Bloomberg Commodity Index<sup>SM</sup>, any investments referenced by or linked to any component of the Bloomberg Commodity Index<sup>SM</sup> or any other related investments and may exercise remedies or take other action with respect to its interests as it deems appropriate.

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&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>SM</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>SM</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>SM</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>SM</sup> thus relies on data that is both endogenous to the futures market (liquidity) and exogenous
to the futures market (production) in determining relative weightings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· DIVERSIFICATION. A second major goal of the Bloomberg Commodity Index<sup>SM</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>SM</sup> is rebalanced annually on a price-percentage basis
in order to maintain diversified commodities exposure over time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· CONTINUITY. A third goal of the Bloomberg Commodity Index<sup>SM</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>SM</sup> from year to year. The Bloomberg Commodity Index<sup>SM</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>SM</sup>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· LIQUIDITY. Another goal of the Bloomberg Commodity Index<sup>SM</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>SM</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 four principles represent goals of the Bloomberg Commodity Index<sup>SM</sup> and its creators, and there can be no assurance that these goals will be achieved.

**Composition of the Bloomberg Commodity Index<sup>SM</sup> — Commodities Available for Inclusion**

Commodities have been selected that are believed to be both sufficiently significant to the world economy to merit consideration for inclusion in the Bloomberg Commodity Index<sup>SM</sup> and that are tradable through a qualifying related futures contract. With the exception of several metals contracts (aluminum, lead, tin, nickel and zinc) that trade on the LME and 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>SM</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 21 commodities included in the Bloomberg Commodity Index<sup>SM</sup> (each, an "Index Commodity" and collectively, the "Index Commodities") for 2022 are as follows: aluminum, coffee, copper, corn, cotton, crude oil, gold, lean hogs, live cattle, low sulphur gas oil, natural gas, nickel, RBOB gasoline, silver, soybean meal, soybean oil, soybeans, sugar, wheat, ULS diesel 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<sup>SM</sup>.

Historically, through and including the composition of the Bloomberg Commodity Index<sup>SM</sup> for 2022, BISL has chosen for each Index 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>SM</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 that Designated Contract.

The 2022 Designated Contracts for the commodities underlying the Bloomberg Commodity Index<sup>SM</sup> are set forth in the table below:

**Bloomberg Commodity Index<sup>SM</sup> Breakdown by Commodity Group**

The table below illustrates the percentage weights for certain commodities and commodity groups in BCOM as of January 2022, based on the principles described above. It should be noted that no single commodity or group dominates the Index, creating a truly diversified commodities benchmark. Additional details in respect to the percentage weights are set forth in Appendix D.

---

| | |
|:---|:---|
| Energy | 29.83% |
| Precious Metals | 19.75% |
| Industrial Metals | 15.48% |
| Livestock | 5.34% |
| Grains | 22.58% |
| Softs | 7.03% |

---

**Determination of Relative Weightings**

The relative weightings of the Index Commodities are determined annually according to both liquidity and 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<sup>SM</sup>, 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<sup>SM</sup>. 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 certain diversification rules to determine the Index Commodities that will be included in the Bloomberg Commodity Index<sup>SM</sup> and their respective percentage weights.

**Diversification Rules**

The Bloomberg Commodity Index<sup>SM</sup> 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<sup>SM</sup>, the following diversification rules are applied to the annual reweighting and rebalancing of the Bloomberg Commodity Index<sup>SM</sup>:

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&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<sup>SM</sup>.

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

The last rule helps to increase the diversification of the Bloomberg Commodity Index<sup>SM</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>SM</sup>, the percentage of any Index Commodity or Commodity Group 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<sup>SM</sup> 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<sup>SM</sup>, 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.

**Calculations**

The excess return version of the Bloomberg Commodity Index<sup>SM</sup> is calculated by BISL by applying the impact of the changes to the futures prices of commodities included in the Bloomberg Commodity Index<sup>SM</sup> (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<sup>SM</sup> 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<sup>SM</sup> excess return level to calculate the new Bloomberg Commodity Index<sup>SM</sup> excess return level.

The total return version of the Bloomberg Commodity Index<sup>SM</sup> is calculated by BISL by applying the impact of the changes in the level of the excess return version of the Bloomberg Commodity Index<sup>SM</sup> 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<sup>SM</sup> 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<sup>SM</sup> (as compared with the prior Bloomberg Commodity Index<sup>SM</sup> excess return level) to obtain the total return. The total return is then applied to the prior Bloomberg Commodity Index<sup>SM</sup> total return level to calculate the new Bloomberg Commodity Index<sup>SM</sup> total return level.

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

The Bloomberg Commodity Index<sup>SM</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 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>SM</sup> is a "rolling index."

With respect to the Bloomberg Commodity Index<sup>SM</sup>, an "Index Business Day" is any day on which the sum of the CIPs (as defined above in "— Determination of Relative Weightings") for the Index Commodities that are open for trading is greater than 50%. For example, based on the weighting of the Index Commodities for 2022, if the CBOT, the NYMEX and the LME are each closed for trading on the same day, an Index Business Day will not exist.

**Bloomberg Commodity Index<sup>SM</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>SM</sup> will be adjusted in the event that BISL determines that any of the following index calculation disruption events exists:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) 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>SM</sup> on that day;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) the failure of an exchange to publish official settlement prices for any futures contract used in the calculation of the Bloomberg Commodity Index<sup>SM</sup>; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) with respect to any futures contract used in the calculation of the Bloomberg Commodity Index<sup>SM</sup> that trades on the LME, an Index Business Day on which the LME is not open for trading.

**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<sup>SM</sup> 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 publisher of the S&P GSCI<sup>®</sup> Indices. The S&P GSCI<sup>®</sup> Indices are determined, composed and calculated by S&P Dow Jones, without regard to the securities. 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 terms supplement.

S&P Dow Jones publishes excess return and total return versions of each of the S&P GSCI<sup>®</sup> Indices. The relevant terms 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>, they are 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.

*Commodity Index Advisory Panel*

S&P Dow Jones has established a commodity index advisory panel (with respect to the S&P GSCI<sup>®</sup> Indices, the "Advisory Panel") to assist it in connection with the operation of the S&P GSCI<sup>®</sup>. The Advisory Panel meets on an annual basis and at other times at the request of the Index Committee. The principal purpose of the Advisory Panel is to advise the Index Committee with respect to, among other things, the calculation of the S&P GSCI<sup>®</sup>, the effectiveness of the S&P GSCI<sup>®</sup> as a measure of commodity futures market performance and the need for changes in the composition or in the methodology of the S&P GSCI<sup>®</sup>. The Advisory Panel acts solely in an advisory and consultative capacity; the Index Committee makes all decisions with respect to the composition, calculation and operation of the S&P GSCI<sup>®</sup>.

"The securities are not sponsored, endorsed, sold or promoted by S&P Dow Jones, Dow Jones, S&P or their respective affiliates or third party licensors (collectively, "S&P Dow Jones Indices"). S&P Dow Jones Indices make no representation or warranty, express or implied, to the holders of the securities or any member of the public regarding the advisability of investing in securities generally or in the securities particularly.

**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 clearing houses, 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 clearing house 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>SM</sup>, Series 1**

All information contained in this underlying supplement regarding the Invesco QQQ Trust<sup>SM</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 Sponsor**"). The QQQ Fund is a unit investment trust that issues securities called "Invesco QQQ Shares." The QQQ Fund is an exchange-traded fund that 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 of 100 of the largest non-financial companies listed on The Nasdaq Stock Market based on market capitalization. For more information about the Nasdaq-100 Index<sup>®</sup>, see "Equity Index Descriptions — The Nasdaq-100 Index<sup>®</sup>."

The QQQ Fund holds securities 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 stocks included in 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>.

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 (the "20+ Treasury Fund") 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 20+ Treasury Fund is an investment portfolio of iShares<sup>®</sup> Trust and is maintained and managed by BFA. BFA is currently the investment adviser to the 20+ Treasury Fund. The 20+ Treasury Fund is an exchange-traded fund ("ETF") that trades on The Nasdaq Stock Market under the ticker symbol "TLT."

The 20+ Treasury Fund 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. On March 31, 2016, the 20+ Treasury Fund ceased tracking the Barclays U.S. 20+ Year Treasury Bond Index and began tracking the ICE U.S. Treasury 20+ Year Bond Index (the "ICE 20+ Year Index"). The ICE 20+ Year Index measures the performance of the U.S. dollar-denominated, fixed-rate U.S. Treasury market that has a remaining maturity of greater than or equal to twenty years. For more information on the ICE 20+ Year Index, please see "The ICE U.S. Treasury 20+ Year Bond Index" below.

BFA uses a representative sampling indexing strategy to manage the 20+ Treasury Fund. "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 capitalization 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 20+ Treasury Fund may or may not hold all of the securities in the ICE 20+ Year Index.

The ICE 20+ Year Index is a financial calculation, based on a grouping of financial instruments, and is not an investment product, while the 20+ Treasury Fund is an actual investment portfolio. The performance of the 20+ Treasury Fund and the ICE 20+ Year Index may vary for a number of reasons, including transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the 20+ Treasury Fund's portfolio and the ICE 20+ Year Index resulting from the 20+ Treasury Fund's use of representative sampling or from legal restrictions (such as diversification requirements) that apply to the 20+ Treasury Fund but not to the ICE 20+ Year Index.

"Tracking error" is the divergence of the performance (return) of the 20+ Treasury Fund's portfolio from that of the ICE 20+ Year Index. BFA expects that, over time, the 20+ Treasury Fund's tracking error will not exceed 5%. Because the 20+ Treasury Fund 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 20+ Treasury Fund. 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 20+ Year 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 20+ Year Index.

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

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

The ICE 20+ Year 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 a minimum remaining term to final maturity of greater than or equal to twenty years as of the last business day of the month (the "Rebalance Date"). Treasury securities that have an announced call are removed from the ICE 20+ Year Index at the end of the month prior to the month in which the call will take place.

*Size.* Each security is required to have a minimum amount outstanding of U.S. $300 million. Amount outstanding is defined as the par amount outstanding of each U.S. Treasury security, inclusive of any announced auctions or re-openings, less the par amount of that U.S. Treasury security held in the Federal Reserve System Open Market Account or bought at issuance by the Federal Reserve. A new issuance bought at auction by the Federal Reserve is not included in the Eligible Bond universe. Secondary market purchases or sales by the Federal Reserve that occur in the current month are reflected in the Eligible Bond universe at the next rebalancing.

*Coupon.* The Eligible Bond universe includes only fixed-rate securities, excluding zero coupon securities.

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

*Bond Type.* Inflation-linked securities, Treasury bills, floating-rate notes, cash-management bills and any government agency debt issued with or without a government guarantee are excluded from the Eligible Bond universe.

***Index Maintenance***

The ICE 20+ Year Index is rebalanced monthly. Securities are required to meet the ICE 20+ Year Index 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 20+ Year Index is rebalanced at each month end. The new ICE 20+ Year Index for the next month is available three days prior to month end and is intended to reflect the constituent changes from the prior rebalancing date based on index eligibility.

*Reinvestment of Cash Flows.* Cash that has accrued intra-month from interest and principal payments by the securities included in the ICE 20+ Year Index earns no reinvestment return during the month. Accumulated cash (from coupon and principal payments) is removed from the ICE 20+ Year Index at month-end, such that the cash is reinvested pro rata across the entire ICE 20+ Year Index.

*New Issues.* Qualifying securities issued on or before the rebalancing date may qualify for inclusion. Issued securities are included in the pro forma ICE 20+ Year Index with a price of U.S. $100 until replaced with an evaluated price as soon as available after auction day.

***Calculation***

Returns and risk measures, such as yield duration, are first calculated at the constituent level and then aggregated to the ICE 20+ Year Index level using its constituents' market weights.

*Constituent Level Calculations*

![](image_044.gif), ![](image_045.gif), ![](image_046.gif), ![](image_047.gif) and ![](image_048.gif) and ![](image_049.gif), ![](image_050.gif), ![](image_051.gif), ![](image_052.gif) and ![](image_053.gif) denote the price, accrued interest, par amount, cumulative coupon payments and market values at date ![](image_054.gif) and date ![](image_055.gif), respectively. C denotes the coupon payments during the period (excluding any coupon payment on date ![](image_054.gif) but including any coupon payment on date ![](image_055.gif)).

Coupon payments during the period are calculated as follows:![](image_056.gif).

The market values at time ![](image_057.gif) and ![](image_058.gif) are: ![](image_059.gif) and ![](image_060.gif), respectively.

The price return![](image_061.gif) and coupon return ![](image_062.gif) (whenever applicable) are defined as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Price return: return due to price appreciation over the return period:

![](image_063.gif)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Coupon return: return due to coupon accrual during the period:

![](image_064.gif)

The total return is the sum of the price return and the coupon return:

![](image_001.jpg)

*Index Level Calculations*

The ICE 20+ Year Index had an initial level of 100 at the inception date. As time passes, the ICE 20+ Year Index level is calculated in an iterative way as follows:

![](image_002.jpg)

The ICE 20+ Year Index total return is calculated by aggregating the constituent level total returns using market weights. To calculate the ICE 20+ Year Index total return for the period from dates ![](image_054.gif) and ![](image_055.gif), market value weights at date ![](image_054.gif) are used. The total market value of the ICE 20+ Year Index at time ![](image_054.gif) is plus any intra-month cash from coupon payment or principal repayment and the weight for constituent security, which is calculated as follows:

![](image_003.jpg)

The ICE 20+ Year Index's level will be provided to four decimal places.

***Index Policies***

*Timing and Pricing Source.* 

The ICE 20+ Year Index's level is calculated using 3:00 p.m. Eastern Standard Time evaluations from PRD. These evaluations are based upon methodologies designed to reflect the market upon which the ICE 20+ Year Index is based.

PRD's bid-side evaluations are market-based measurements that are processed through a rules-based pricing application and represent its good faith determinations as to what the holder would receive in an orderly transaction (for an institutional round lot position, typically $1,000,000 or greater current value in U.S. dollars or local currency equivalent) under current market conditions. The rules based logic utilizes valuation techniques that may vary by asset class and per methodology, maximize the use of relevant observable data including quoted prices for similar assets, benchmark yield curves and market corroborated inputs. For example, its pricing applications are coded to review trades and bids to determine that the lot size is representative of an institutional round lot, though smaller or retail sized lots may be considered, especially if this is the only or primary trading information available.

PRD's evaluators meet regularly to discuss market movements and other macro-economic information. PRD evaluates U.S. Treasury securities by obtaining feeds continuously from a number of live data sources including active market makers and inter-dealer brokers. Sources are reviewed on the basis of their historical accuracy for individual issues and maturity ranges. As new information is received, it is compared against the previous evaluation as part of the daily process. To provide additional transparency into its procedures, controls and governing processes, PRD adopted a code of conduct which enables benchmark administrators, like IDI, to exercise oversight of the benchmark setting process in conformance with the IOSCO Principles. IDI also maintains a verification process designed to identify price tolerance breaks for further investigation.

*Calendar*. The ICE 20+ Year Index follows the SIFMA U.S. bond market holiday schedule. The ICE 20+ Year 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 20+ Year 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 20+ Year Index's level.

*Exceptional Market Conditions and Corrections*. IDI retains the right to delay the publication of the level of the ICE 20+ Year Index. Furthermore, IDI retains the right to suspend the publication of the level of the ICE 20+ Year Index if it believes that circumstances prevent the proper calculation of the ICE 20+ Year Index. If evaluated prices are not available, the ICE 20+ Year 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 20+ Year 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.

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 20+ Year 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.

*Expert Judgment*. In cases which are not expressly covered in the index rules, operational adjustments may take place along the lines of the aim of the ICE 20+ Year Index. Operational adjustments may also take place if, in the opinion of IDI, it is desirable to do so to maintain the integrity of the ICE 20+ Year Index. Any such modifications described under this section or exercise of expert judgment will be based upon the IDI's Index Design Principles, which detail the core design principles adhered to IDI in establishing an ICE 20+ Year Index determination specific to the ICE 20+ Year Index. "Expert Judgment" refers to the exercise of discretion by the IDI with respect to the use of data in determining a benchmark. 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's or seller's credit quality or weighting firm bids or offers greater than a particular concluded transaction. Any exercise of expert judgment will be overseen by the ICE Data Indices, LLC Governance Committee (for purposes of this section, the "Index Committee"). The IDI Index Design Principles are available on request to PRD.

*Index Reviews*. IDI undertakes regular reviews of the ICE 20+ Year Index, the methodology and the market which it represents to ensure it continues to meet the index objective, in accordance with IDI's policies and procedures. Should material changes to the ICE 20+ Year Index be required or proposed, this will be communicated to stakeholders and subscribers in accordance with IDI's consultation policy, where possible.

*Consultations*. IDI may from time to time consult with stakeholders and subscribers on proposed material changes that affect the ICE 20+ Year Index in accordance with IDI's consultation process. These proposals will be published to stakeholders and subscribers and all feedback received will be considered by IDI. Any resulting changes to the ICE 20+ Year Index will be announced prior to it being implemented.

*Restatements.* IDI reserves the right to restate the ICE 20+ Year Index's level based on its discretion. The ICE 20+ Year Index subscribers are notified prior to a restatement of data. Restatements are typically communicated on the same day but may take longer depending on the volume of restatements required and other conditions.

***Index Governance***

The Index Committee is responsible for governance and oversight of the ICE 20+ Year Index. The Index Committee provides oversight to IDI that has daily responsibilities for the development, issuance and operation of the ICE 20+ Year Index.

The Index Committee will approve any necessary changes in the ICE 20+ Year Index's methodology. The IDI is then responsible for implementing the changes and notifying subscribers. Where a change is material, IDI will consult with stakeholders and subscribers in accordance with the IDI consultation process. For other changes, advance notice will be provided, where possible, to allow stakeholders and subscribers appropriate preparation to implement the change.

**The iShares<sup>®</sup> ETFs**

All information contained in this underlying supplement regarding the iShares<sup>®</sup> MSCI Brazil ETF, the iShares<sup>®</sup> MSCI Emerging Markets ETF, the iShares<sup>®</sup> MSCI EAFE ETF, the iShares<sup>®</sup> MSCI Japan ETF, the iShares<sup>®</sup> MSCI Mexico ETF, the iShares<sup>®</sup> Nasdaq Biotechnology 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<sup>®</sup> ETF" and collectively, the "iShares<sup>®</sup> 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<sup>®</sup> ETF and BlackRock Fund Advisors ("BFA"). The iShares<sup>®</sup> 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 adviser to the iShares<sup>®</sup> ETFs. The iShares<sup>®</sup> ETFs (except for the iShares<sup>®</sup> Nasdaq Biotechnology ETF) are exchange-traded funds that trade on the NYSE Arca, Inc. under their respective ticker symbols. The iShares<sup>®</sup> Nasdaq Biotechnology ETF is an exchange-traded fund that trades on The Nasdaq Stock Market ("Nasdaq") under its ticker symbol.

BFA uses a representative sampling indexing strategy to manage each iShares<sup>®</sup> 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 capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of an applicable underlying index. Each iShares<sup>®</sup> ETF may or may not hold all of the securities in its respective underlying index.

Each iShares<sup>®</sup> ETF's underlying index is a financial calculation, based on a grouping of financial instruments, and is not an investment product, while each iShares<sup>®</sup> ETF is an actual investment portfolio. The performance of each iShares<sup>®</sup> ETF and its underlying index may vary for a number of reasons, including transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between that iShares<sup>®</sup> ETF's portfolio and its underlying index resulting from that iShares<sup>®</sup> ETF's use of representative sampling or from legal restrictions (such as diversification requirements) that apply to that iShares<sup>®</sup> ETF but not to its underlying index. "Tracking error" is the divergence of the performance (return) of an iShares<sup>®</sup> ETF's portfolio from that of its underlying index. Because each iShares<sup>®</sup> 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 and iShares<sup>®</sup>, Inc. are registered investment companies that consist of numerous separate investment portfolios, including the iShares<sup>®</sup> ETFs.

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

All information contained in this underlying supplement regarding the 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 Nasdaq, Inc. The Biotechnology Index was developed and is calculated, maintained and published by Nasdaq, Inc. Nasdaq, Inc. does not have any obligation to continue to publish, and may discontinue publication of, the Biotechnology Index.

*General*

The Nasdaq Biotechnology Index is designed to measure the performance of a set of Nasdaq-listed biotechnology and pharmaceutical companies. The Biotechnology Index is reported by Bloomberg L.P. under the ticker symbol "NBI."

*Security Eligibility Criteria*

*Eligible security types*. Eligible security types generally include American Depositary Receipts (ADRs), common stocks, ordinary shares, shares of beneficial interest and limited partnership interests.

If the security is a depositary receipt representing a security of a non-U.S. issuer, then references to the "issuer" are references to the underlying security and the total shares outstanding is the actual depositary shares outstanding as reported by the depositary banks.

The issuer of a component security must meet the following criteria:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the issuer of a security's primary U.S.
listing must exclusively be listed on the Nasdaq Global Select Market or the Nasdaq Global Market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the security must be classified under the Biotechnology
Subsector or Pharmaceuticals Subsector according to the Industry Classification Benchmark (ICB), a product of FTSE International Limited
that is licensed for this use;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the issuer of the security generally may not
currently be in bankruptcy proceedings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the issuer of the security generally may not
have entered into a definitive agreement or other arrangement that would make it ineligible for Index inclusion and where the transaction
is imminent as determined by the Index Management Committee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· each security must have a market capitalization
of $200 million;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· each security must have a minimum average daily
trading volume (ADTV) of 100,000 shares (measured from the start of the year up to the reconstitution reference date); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the security must have traded for at least three
full calendar months, not including the month of initial listing, on an eligible exchange, which includes Nasdaq (Nasdaq Global Select
Market, Nasdaq Global Market, or Nasdaq Capital Market), NYSE, NYSE American or CBOE BZX. Eligibility is determined as of the constituent
selection reference date, and includes that month. A security that was added to the index as the result of a spin-off event will be exempt
from the seasoning requirement.

All securities that meet the applicable Security Eligibility Criteria are included in the Index

*Multiple classes of securities*. If an issuer has listed multiple security classes, all security classes are eligible, subject to meeting all other security eligibility criteria.

*Calculation of the Biotechnology Index*

The Nasdaq Biotechnology Index is a modified market capitalization weighted index. NBI employs a two-stage weight adjustment scheme. Index Securities' initial weights are determined by dividing each Index security's market capitalization by the aggregate market capitalization of all Index securities:

Stage 1: Initial index weights are adjusted to meet the following Stage 1 constraint, producing the Stage 1 weights:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· No Index security weight may exceed 8%.

Stage 2: Stage 1 weights are adjusted to meet the following Stage 2 constraints, producing the final weights:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· For Index securities with the five largest market
capitalizations, Stage 1 weights are maintained.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· For all other Index securities, no weight may
exceed 4%.

The final weights meet the following constraints:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· No Index security weight may exceed 8% of the
index; five may exceed 4%.

*Biotechnology Index Calendar*

The constituents of the Biotechnology Index are selected by Nasdaq once annually in December. The eligibility criteria described above are applied using market data as of the end of October and total shares outstanding as of the end of November. Index reconstitutions are announced in early December and become effective after the close of trading on the third Friday in December.

The Index is rebalanced on a quarterly basis in March, June, September and December. The Index rebalance uses the Total Shares Outstanding ("TSO") and Last Sale Price ("LSP") of all Index securities as of the prior month-end (February, May, August and November respectively). Index rebalance changes are announced in early March, June, September and December, and changes become effective after the close of trading on the third Friday in March, June, September and December.

*Biotechnology Index Maintenance*

*Deletion policy.* If, at any time other than an Index reconstitution, Nasdaq determines that an Index security is ineligible for Index inclusion, the Index security is removed as soon as practicable and is not replaced.

This may include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· listing on an ineligible index exchange;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· a security is not classified under the Biotechnology
Subsector or Pharmaceuticals Subsector according to the Industry Classification Benchmark (ICB), a product of FTSE International Limited
that is licensed for this use;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· merger, acquisition, or other major corporate
event that would otherwise adversely impact the integrity of the Index.

In the case of mergers and acquisitions, the effective date for the removal of an Index issuer or security will be largely event-based, with the goal to remove the issuer or security as soon as completion of the acquisition or merger has been deemed highly probable. Notable events include, but are not limited to, completion of various regulatory reviews, the conclusion of material lawsuits and/or shareholder and board approvals.

Securities that are added as a result of a spin-off may be deleted as soon as practicable after being added to the index. This may occur when Nasdaq determines that a security is ineligible for inclusion because of reasons such as ineligible exchange, security type, or industry. Securities that are added as a result of a spin-off may be maintained in the Index until a later date and then removed, for example if a spin-off security has liquidity or market capitalization characteristics that diverge materially from the security eligibility criteria and could affect the integrity of the Index.

*Replacement policy.* Index securities are not replaced in the Index outside of the Index reconstitution.

*Corporate actions.* In the periods between scheduled Index reconstitution and rebalancing events, individual Index securities may be the subject to a variety of corporate actions and events that require maintenance and adjustments to the Index. With the exception(s) noted below, specific treatment of each type of corporate action or event is described in "Nasdaq Corporate Actions and Events Manual – Equities".

In certain cases, corporate actions and events are handled according to the weighting scheme or other index construction techniques employed. Wherever alternate methods are described, the Index will follow the "Market Cap Corporate Action Method."

At the quarterly rebalancing, no changes are made to the Index from the previous month end until the quarterly share change effective date, with the exception of corporate actions with an ex-date. Index share adjustments

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

All information contained in this underlying supplement regarding the Dow Jones U.S. Real Estate 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 Index is calculated, maintained and published by S&P Dow Jones. S&P Dow Jones is under no obligation to continue to publish, and may discontinue publication of, the Dow Jones U.S. Real Estate Index. The Dow Jones U.S. Real Estate Index is reported by Bloomberg L.P. under the ticker symbol "DJUSRE."

*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 real estate investment trusts (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 19 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 float-adjusted market capitalization, excluding the most thinly traded securities. The Dow Jones U.S. Real Estate Index is weighted by float-adjusted market capitalization, 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 investable weight factor (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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 12-Month Median Value Traded Ratio (MVTR). Stocks must have an MVTR of at
least 20%. Current constituents remain eligible if they have an 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 float-adjusted market capitalization. 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; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 6-Month Median Daily Value Traded (MDVT). Stocks must have an MDVT over the
six months prior to the rebalancing reference date of at least US$250,000. Current constituents remain eligible if they have an 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 float-adjusted market capitalization. Stocks in the top 95% of the index universe by float-adjusted market capitalization 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 float-adjusted market capitalization. Non- constituents are eligible up to the 93rd percentile as ranked by float-adjusted market capitalization. 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 Real Estate Index is calculated by means of the divisor methodology. On any given day, the index value is the quotient of the total float-adjusted market capitalization 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' 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 SPDR<sup>®</sup> Fund employs a replication strategy, which means that each Select Sector SPDR<sup>®</sup> 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 SPDR<sup>®</sup> 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. For example, it may take several business days for additions and deletions to the relevant Select Sector Index to be reflected in the portfolio composition of the Select Sector Fund.

The Select Sector Trust is a registered investment company that consists of a separate investment portfolio for each of the Select Sector SPDR<sup>®</sup> 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.

For more information about the EURO STOXX 50<sup>®</sup> Index, please see "Equity Index Descriptions — The EURO STOXX 50<sup>®</sup> Index" 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.

**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 — S&P U.S. Indices" in this underlying supplement. The SPY Fund seeks to achieve its investment objective by holding a portfolio of the 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 to 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).

In seeking to track the performance of the relevant Select Industry Index, each SPDR<sup>®</sup> S&P<sup>®</sup> Industry ETF employs a "sampling" strategy, which means that the SPDR<sup>®</sup> S&P<sup>®</sup> Industry ETF is not required to purchase all of the securities represented in the relevant Select Industry Index. Instead, each SPDR<sup>®</sup> S&P<sup>®</sup> 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 of the relevant Select Industry Index. The quantity of holdings in each SPDR<sup>®</sup> S&P<sup>®</sup> Industry ETF will be based on a number of factors, including asset size of that SPDR<sup>®</sup> S&P<sup>®</sup> Industry ETF. Based on its analysis of these factors, SSGA FM either may invest each SPDR<sup>®</sup> S&P<sup>®</sup> Industry ETF's assets in a subset of securities in the relevant Select Industry Index or may invest that SPDR<sup>®</sup> S&P<sup>®</sup> 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<sup>®</sup> S&P<sup>®</sup> 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<sup>®</sup> S&P<sup>®</sup> Industry ETF's return may not match the return of the relevant Select Industry Index. Each SPDR<sup>®</sup> S&P<sup>®</sup> Industry ETF incurs a number of operating expenses not applicable to the relevant Select Industry Index, and incurs costs in buying and selling securities. In addition, an SPDR<sup>®</sup> S&P<sup>®</sup> Industry ETF may not be fully invested at times, generally as a result of cash flows into or out of that SPDR<sup>®</sup> S&P<sup>®</sup> Industry ETF or reserves of cash held by that SPDR<sup>®</sup> S&P<sup>®</sup> Industry ETF to meet redemptions. SSGA FM may attempt to replicate the relevant Select Industry Index's 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 an SPDR<sup>®</sup> S&P<sup>®</sup> Industry ETF's return and that of the relevant Select Industry Index.

**The United States USO Fund, LP**

All information contained in this underlying supplement regarding the United States USO 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**"), 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 will be measured by the futures contract that is the next month contract 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 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 (or 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 333-237750 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. Van Eck anticipates that, generally, each VanEck ETF will hold or gain exposure to all of the securities that comprise its underlying index in proportion to their weightings in such underlying index. However, under various circumstances, it may not be possible or practicable to purchase all of those securities in those weightings. In these circumstances, a VanEck ETF may purchase a sample of securities in its underlying index. There also may be instances in which Van Eck may choose to underweight or overweight a security in a VanEck ETF's underlying index, purchase securities not in the VanEck ETF's underlying index that Van Eck believes are appropriate to substitute for certain securities in such underlying index or utilize various combinations of other available investment techniques in seeking to replicate as closely as possible, before fees and expenses, the price and yield performance of the VanEck ETF's 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. 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. For tax efficiency purposes, a VanEck ETF may sell certain securities, and such 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 NYSE Arca 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, the NYSE Arca. The Gold Miners Index is calculated, maintained and published by the NYSE Arca. The NYSE Arca has no obligation to continue to publish, and may discontinue the publication of, the Gold Miners Index.

The Gold Miners Index is a modified market capitalization-weighted index composed of publicly traded companies involved primarily in the mining of gold or silver. The Gold Miners Index is reported by Bloomberg L.P. under the ticker symbol "GDM."

*Eligibility Criteria for Index Components*

The Gold Miners Index includes common stocks, American depositary receipts ("**ADRs**") and Global depositary receipts ("**GDRs**") of selected companies that are involved in mining for gold and silver and that are listed for trading on a major stock market that is accessible by foreign investors. Only companies with market capitalization greater than $750 million that have an average daily trading volume of at least 50,000 shares over the past three months and an average daily value traded of at least $1 million over the past three months are eligible for inclusion in the Gold Miners Index. For companies that were already in the Gold Miners Index prior to the September 20, 2013 rebalance, the market capitalization requirement is $450 million, the average daily trading volume requirement is at least 30,000 shares over the past three months and the average daily value traded requirement is at least $600,000 over the past three months. Further, the universe of companies eligible for inclusion in the Gold Miners Index will specifically include those companies that derive at least 50% of their revenues from gold mining and related activities. Companies already in the Gold Miners Index will be removed from the Gold Miners Index in the following quarterly review only if their gold mining revenues fall below the 40% level. The Gold Miners Index will maintain an exposure, of not more than 20% of the Gold Miners Index weight at rebalance, to companies with a significant revenue exposure to silver mining as well as gold mining. These are companies that either (1) have a revenue exposure to silver mining greater than 50% or (2) have a greater revenue exposure to silver mining than gold mining and have a combined gold/silver mining revenue exposure of greater than 50%.

In addition, both streaming companies and royalty companies are eligible for inclusion in the Gold Miners Index. Companies that have not yet commenced production are also eligible for inclusion in the Gold Miners Index, *provided* that they have tangible revenues that are related to the mining of either gold or silver ore. There are no restrictions imposed on the eligibility of company in how much the company has hedged in gold or silver production via futures, options or forward contracts.

*Index Calculation*

The Gold Miners Index is calculated using a modified market capitalization weighting methodology. The Gold Miners Index is weighted based on the market capitalization of each of the component securities, modified to conform to the following asset diversification requirements, which are applied in conjunction with the scheduled quarterly adjustments to the Gold Miners Index. The information utilized in this modification process will be taken from the close of trading on the second Friday of the rebalancing month:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) the weight of any single component security may not account for more than 20% of the total value of the Gold Miners Index;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) the component securities are split into two subgroups — (1) large and (2) small, which are ranked by their unadjusted market capitalization weight in the Gold Miners Index. Large stocks are defined as having a Gold Miners Index weight greater than or equal to 5%. Small securities are defined as having an Gold Miners Index weight below 5%; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) the final aggregate weight of those component securities which individually represent more than 4.5% of the total value of the Gold Miners Index may not account for more than 45% of the total Gold Miners Index value.

The Gold Miners Index is reviewed quarterly so that the Gold Miners Index components continue to represent the universe of companies involved in the gold mining industry. The NYSE Arca may at any time and from time to time change the number of securities composing the group by adding or deleting one or more securities, or replacing one or more securities contained in the group with one or more substitute securities of its choice, if in the NYSE Arca's discretion such addition, deletion or substitution is necessary or appropriate to maintain the quality and/or character of the Gold Miners Index. Changes to the Gold Miners Index compositions and/or the component share weights in the Gold Miners Index typically take effect after the close of trading on the third Friday of each calendar quarter month in connection with the quarterly index rebalance.

At the time of the quarterly rebalance, the quantities for the components stocks (taking into account expected component changes and share adjustments), are modified in accordance with the following procedures.

· Diversification Rule 1: If any component stock exceeds 20% of the total value
of the Gold Miners Index, then all stocks greater than 20% of the Gold Miners Index are reduced to represent 20% of the value of the Gold
Miners Index. The aggregate amount by which all component stocks are reduced is redistributed proportionately across the remaining stocks
that represent less than 20% of the index value. After this redistribution, if any other stock then exceeds 20%, the stock is set to 20%
of the index value and the redistribution is repeated. If there is no component stock over 20% of the total value of the Gold Miners Index,
then Diversification Rule 1 is not executed.

· Diversification Rule 2: The components are sorted into two groups, (1) large
components, with a starting index weight of 5% or greater, and (2) small components, with a weight of under 5% (after any adjustments
for Diversification Rule 1). If there are no components that are classified as large components after Diversification Rule 1 is run, then
Diversification Rule 2 is not executed. In addition, if the starting aggregate weight of the large components after Diversification Rule
1 is run is not greater than 45% of the starting index weight, then Diversification Rule 2 is not executed. If Diversification Rule 2
is executed, then the large group and the small group will represent 45% and 55%, respectively, of the final index weight. This will be
adjusted for through the following process:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o The weight of each of the large stocks will be scaled down proportionately with a floor of 5% so that the aggregate weight of the
large components will be reduced to represent 45% of the Gold Miners Index. If any component stock falls below a weight equal to the product
of 5% and the proportion by which the stocks were scaled down following this distribution, then the weight of the stock is set equal to
the product of 5% and the proportion by which the stocks were scaled down, the components with weights greater than 5% will be reduced
proportionately.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o The weight of each of the small components will be scaled up proportionately from the redistribution of the large components. If any
component stock exceeds a weight equal to the product of 4.5% and the proportion by which the stocks were scaled up following this distribution,
then the weight of the stock is set equal to the product of 4.5% and the proportion by which the stocks were scaled up. The redistribution
of weight to the remaining stocks is repeated until the entire amount has been redistributed.

*Index Maintenance*

The Gold Miners Index is reviewed quarterly to ensure that at least 90% of the index weight is accounted for by index components that continue to meet the initial eligibility requirements. Components will be removed from the Gold Miners Index during the quarterly review if either (1) the market capitalization falls below $450 million or (2) the average daily volume traded for the previous three months was lower than 30,000 shares and the average daily value traded for the previous three months was lower than $600,000. In conjunction with the quarterly review, the share quantities used in the calculation of the Gold Miners Index are determined based upon current shares outstanding modified, if necessary, to provide greater index diversification, as described above. An ADR or GDR ratio would be incorporated into this shares figure so that the shares utilized in the Gold Miners Index for a depositary receipt is equal to the shares outstanding of the local share class multiplied by the depositary receipt ratio. The index components and their share quantities are determined and announced prior to taking effect. The share quantity of each component stock in the index portfolio remains fixed between quarterly reviews except in the event of certain types of corporate actions, such as stock splits, reverse stock splits, stock dividends or similar events. The share quantities used in the index calculation are not typically adjusted for shares issued or repurchased between quarterly reviews. However, in the event of a merger between two components, the share quantity of the surviving entity may be adjusted to account for any stock issued in the acquisition. The NYSE Arca may substitute stocks or change the number of stocks included in the Gold Miners Index based on changing conditions in the industry or in the event of certain types of corporate actions, including mergers, acquisitions, spin-offs, and reorganizations. In the event of component or share quantity changes to the index portfolio, the payment of dividends other than ordinary cash dividends, spin-offs, rights offerings, re-capitalization or other corporate actions affecting a component stock of the Gold Miners Index, the index divisor may be adjusted to ensure that there are no changes to the index level as a result of non-market forces.

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 the 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 the global gold and silver mining small-cap segment, which includes companies that derive at least 50% (25% for current components) of their revenues from gold mining/royalties/streaming and/or silver mining/royalties/streaming 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 Junior Gold Miners Index is reported by Bloomberg L.P. under the ticker symbol "MVGDXJ."

*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. The Oil Services Index was launched on August 12, 2011 with a base index value of 1,000 as of September 29, 2000. The Oil Services Index is reported by Bloomberg L.P. under the ticker symbol "MVOIH."

*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 Semiconductor Index is reported by Bloomberg L.P. under the ticker symbol "MVSMH."

*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 and cannabis/marijuana companies are excluded. 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
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.

In case the number of investable stocks drops below the minimum component number for the relevant MVIS Index, additional companies are flagged eligible by MVIS's decision until the number of eligible stocks equals the minimum component count.

Only one share line of each company is eligible. In case 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.

In case 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 reviewed on a quarterly basis. The target coverage of the Junior Gold Miners Index is 100% of the free float market capitalization of the investable small-cap universe with at least 25 companies. 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 reviewed 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 up.

&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;&nbsp;&nbsp;&nbsp;&nbsp;a. Initially, the highest ranked 25 companies made up the relevant MVIS US Listed 25 Index.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. On-going, 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. If the number of selected companies is still below 25, then the highest
ranked remaining stocks are selected until 25 companies have been selected.

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:

![](image_070.gif)

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> = sector-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 Sector-Weighting Cap Factor*

Companies determined to be silver stocks must not constitute more than 20% of the Junior Gold Miners Index. If at a quarterly review, the aggregated weighting of all silver stocks represents more than 20% of the Junior Gold Miners Index, a sector-weighting cap factor is applied. This sector-weighting cap factor is calculated to ensure that the aggregated weighting of all gold stocks will not be less than 80% and the aggregated weighting of all silver stocks is be capped at 20%.

 *Junior Gold Miners Index Company-Weighting Cap Factors*

Companies in the Junior Gold Miners Index are ranked according to their free float market capitalization, as modified by the company-weighting cap factors. The Junior Gold Miners Index uses the company-weighting cap factors to ensure diversification to avoid overweighting. The company-weighting cap factors are reviewed quarterly and applied, if necessary. The following weighting scheme applies to the Junior Gold Miners Index:

&nbsp;&nbsp;&nbsp;&nbsp;(1) All companies are ranked by their free float market capitalization. The maximum weight for any single
stock is 8%. If a stock exceeds the maximum weight, then the weight will be reduced to the maximum weight and the excess weight shall
be redistributed proportionally across all other Junior Gold Miners Index constituents. This process is repeated until no stocks
have weights exceeding the respective maximum weight.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The 8%-cap weighting scheme will be applied to the largest stocks and the excess weight after each step
shall be redistributed across all other (uncapped) stocks in the Junior Gold Miners Index on a proportional basis:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. If the largest two stocks exceed 8%, both will be capped at 8%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. If the third largest stock exceeds 7%, it will be capped at 7%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. If the fourth largest stock exceeds 6.5%, it will be capped at 6.5%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d. If the fifth largest stock exceeds 6%, it will be capped at 6%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e. If the sixth largest stock exceeds 5.5%, it will be capped at 5.5%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f. If the seventh largest stock exceeds 5%, it will be capped at 5%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;g. If any other stock exceeds 4.5%, it will be capped at 4.5%.

&nbsp;&nbsp;&nbsp;&nbsp;(3) The maximum weight of any single silver stock is 4.5% in the Junior Gold Miners Index.

*MVIS US Listed 25 Index Company-Weighting Cap Factors*

Companies in each MVIS US Listed 25 Index are weighted according to their free float market capitalization, as modified by the company-weighting cap factors. The MVIS US Listed 25 Indices use the company-weighting cap factors to ensure diversification to avoid overweighting. The company-weighting cap factors are reviewed quarterly and applied, if necessary. The following weighting scheme applies to the MVIS US Listed 25 Indices:

&nbsp;&nbsp;&nbsp;&nbsp;(1) All index components are weighted by their free float market capitalization.

&nbsp;&nbsp;&nbsp;&nbsp;(2) 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;(3) The aggregated weighting of the Large-Weights is capped at 50%:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. 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;b. 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;c. 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**

All information contained in this underlying supplement regarding the Vanguard FTSE Emerging Markets ETF has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, Vanguard International Equity Index Funds (the "Vanguard International Trust") and The Vanguard Group, Inc. ("Vanguard"). The Vanguard FTSE Emerging Markets ETF is an investment portfolio of the Vanguard International Trust. Vanguard is the investment adviser to the Vanguard FTSE Emerging Markets ETF. The Vanguard FTSE Emerging Markets ETF is an exchange-traded fund that trades on the NYSE Arca, Inc. under the ticker symbol "VWO."

The Vanguard FTSE Emerging Markets ETF seeks to track, before fees and expenses, the performance of a benchmark index that measures the investment return of stocks issued by companies located in emerging market countries. The benchmark index is currently the FTSE Emerging Markets All Cap China A Inclusion Index (the "Emerging Markets Index"). For more information about the Emerging Markets Index, see "The FTSE Emerging Markets All Cap China A Inclusion Index" below.

The index tracked by the Vanguard FTSE Emerging Markets ETF has changed over time. The Vanguard FTSE Emerging Markets ETF tracked the Select Emerging Markets Index through August 23, 2006; the MSCI Emerging Markets Index through January 9, 2013; the FTSE Emerging Transition Index through June 27, 2013; the FTSE Emerging Markets Index through November 1, 2015; and the FTSE Emerging Markets All Cap China A Transition Index through September 18, 2016. Since September 19, 2016, the Vanguard FTSE Emerging Markets ETF has tracked the Emerging Markets Index. Korean companies were first included as part of the transition to the FTSE Emerging Markets Index, and small-capitalization stocks and China A-shares were first included as part of the transition to the Emerging Markets Index. These changes could adversely affect the performance of the Vanguard FTSE Emerging Markets ETF. In addition, there is limited historical information that reflects the Vanguard FTSE Emerging Markets ETF's tracking of the Emerging Markets Index.

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 Vanguard International Trust is a registered investment company that consists of numerous separate investment portfolios, including the Vanguard FTSE Emerging Markets ETF.

**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-cap 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 securities from 23 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 49 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
clearing house; 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 3 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;&nbsp;&nbsp;&nbsp;&nbsp;· The investor protection regulations present in the country of incorporation;

&nbsp;&nbsp;&nbsp;&nbsp;&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;&nbsp;&nbsp;&nbsp;&nbsp;· The location of its factors of production;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The location of its headquarters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The location of company meetings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The composition of its shareholder base;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The membership of its board of directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The currency denomination of the company's shares;

&nbsp;&nbsp;&nbsp;&nbsp;&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_093.gif)

Where

![](image_094.gif) 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_095.gif) 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:

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 on the respective regional Small Cap Index. Individual securities will be tested against the relevant regional levels.

---

| | | |
|:---|:---|:---|
| **Region** | **For Inclusion (New Stocks)** | **For Inclusion (Current Stocks)** |
| Asia Pacific ex China ex Japan | 0.05% | 0.01% |
| China (A, B, H, N Share, P, Red and S Chip) | 0.10% | 0.02% |
| Latin America | 0.50% | 0.20% |
| Emerging Europe<br> Middle East & Africa | 1.00% | 0.20% |

---

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 outlined 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." Shares being offered as a greenshoe (over allotment option) will be excluded from the investable
market capitalization calculation.

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.
