Selected Risk Considerations

An investment in the notes involves significant risks. Investing in the notes is not equivalent to investing directly in the Reference Assets. These risks are explained in more detail in the “Additional Risk Factors Relating to the Notes” section of the product supplement.

Risks Related to the Structure or Features of the Notes

Risks Related to the Reference Assets

Neither the offering of the notes nor any views which our affiliates from time to time may express in the ordinary course of their businesses constitutes a recommendation as to the merits of an investment in the notes.

Risks Relating to the Utilities Select Sector SPDR^® Fund

An investment in the notes is subject to risks associated with investments in securities with a concentration in the utilities sector. — All or substantially all of the securities tracked by the Utilities Select Sector SPDR^® Fund are stocks of companies whose primary business is directly associated with the utilities sector. Because the value of the notes is linked to the performance of the Utilities Select Sector SPDR^® Fund , an investment in the notes exposes investors to risks associated with investments in securities with a concentration in the utilities sector. Utility companies are affected by supply and demand, operating costs, government regulation, environmental factors, liabilities for environmental damage and general civil liabilities and rate caps or rate changes. Although rate changes of a regulated utility usually fluctuate in approximate correlation with financing costs, due to political and regulatory factors, rate changes ordinarily occur only following a delay after the changes in financing costs. This factor will tend to favorably affect a regulated utility company’s earnings and dividends in times of decreasing costs, but, conversely, will tend to adversely affect earnings and dividends when costs are rising. The value of regulated utility equity securities may tend to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable. In addition, natural disasters, terrorist attacks, government intervention or other factors may render a utility company’s equipment unusable or obsolete and negatively impact profitability. Among the risks that may affect utility companies are the following: risks of increases in fuel and other operating costs; the high cost of borrowing to finance capital construction during inflationary periods; restrictions on operations and increased costs and delays associated with compliance with environmental and nuclear safety regulations; and the difficulties involved in obtaining natural gas for resale or fuel for generating electricity at reasonable prices. Other risks include those related to the construction and operation of nuclear power plants, the effects of energy conservation and the effects of regulatory changes. The value of the notes may be subject to greater volatility and be more adversely affected by a single economic, political or regulatory occurrence affecting the utilities sector than a different investment linked to securities of a more broadly diversified group of issuers.

General Risk Factors

Examples of the Hypothetical Payment at Maturity for a $1,000 Investment in the Notes

The following examples illustrates the hypothetical payments on a note upon an automatic call or at maturity. The hypothetical payments are based on a $1,000 investment in the note, a hypothetical Initial Level of 100.00, a hypothetical Trigger Level of 70.00 (70.00% of the hypothetical Initial Level), a hypothetical Call Level of 100.00 (100.00% of the hypothetical Initial Level), hypothetical Call Amounts representing a return of approximately 11.96% per annum, a range of hypothetical closing levels and the effect on the payment of the notes.

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

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

Example 1: The closing level of the Least Performing Reference Asset increases by 10.00% from the Initial Level to a closing level of 110.00 on the first Observation Date. Because the closing level of each Reference Asset on the first Observation Date is greater than its Call Level, the investor receives on the first Call Settlement Date a cash payment of $1,059.80, representing the principal amount plus the corresponding hypothetical Call Amount. After the notes are called, they will no longer remain outstanding and there will be no further payments on the notes.

Example 2: The closing level of the Least Performing Reference Asset decreases by 10% from the Initial Level to a closing level of 90.00 on the first Observation Date, but the closing level of the Least Performing Reference Asset increases by 10% from the Initial Level to a closing level of 110.00 on the second Observation Date. Because the notes are not called on the first Observation Date and the closing level of each Reference Asset on the second Observation Date is greater than its Call Level, the investor receives on the second Call Settlement Date a cash payment of $1,089.70, representing principal amount plus the corresponding hypothetical Call Amount. After the notes are called, they will no longer remain outstanding and there will be no further payments on the notes.

Example 3: The notes are not called on any of the Observation Dates prior to the final Observation Date, and the closing level of the Least Performing Reference Asset increases by 20% from the Initial Level to 120.00 on the Valuation Date. Because the notes are not called on any of the preceding Observation Dates and the closing level of each Reference Asset on the Valuation Date is greater than its Call Level, the investor receives on the maturity date a cash payment of $1,239.20, representing the principal amount plus the corresponding hypothetical Call Amount.

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

Example 4: The closing level of the Least Performing Reference Asset decreases by 25.00% from the Initial Level to its Final Level of 75.00 on the Valuation Date. The notes are not called on any Observation Date because the closing level of at least one Reference Asset is below its Call Level on each Observation Date (including the Valuation Date). Because the Final Level of the Least Performing Reference Asset is less than its Initial Level but is greater than its Trigger Level, the investor receives at maturity, a cash payment of $1,000 per note, despite the decline in the closing level of the Least Performing Reference Asset.

Example 5: The closing level of the Least Performing Reference Asset decreases by 40.00% from the Initial Level to its Final Level of 60.00 on the Valuation Date, which is less than its Trigger Level. The notes are not called on any Observation Date because the closing level of at least one Reference Asset is below its Call Level on each Observation Date (including the Valuation Date). Because the Final Level of the Least Performing Reference Asset is less than its Initial Level as well as its Trigger Level, the investor receives at maturity, a cash payment of $600.00 per note, calculated as follows:

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

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

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

U.S. Federal Tax Information

By purchasing the notes, each holder agrees (in the absence of a change in law, an administrative determination or a judicial ruling to the contrary) to treat each note as a pre-paid derivative contract for U.S. federal income tax purposes. In the opinion of our counsel, Mayer Brown LLP, it would generally be reasonable to treat the notes as pre-paid derivative contracts in respect of the Reference Assets for U.S. federal income tax purposes. However, the U.S. federal income tax consequences of your investment in the notes are uncertain and the Internal Revenue Service could assert that the notes should be taxed in a manner that is different from that described in the preceding sentence. Please see the discussion in the accompanying product supplement under "Supplemental Tax Considerations—Supplemental U.S. Federal Income Tax Considerations—Notes Treated as an Investment Unit Consisting of a Debt Portion and a Put Option, as a Pre-Paid Contingent Income-Bearing Derivative Contract, or as a Pre-Paid Derivative Contract—Notes Treated as a Pre-Paid Derivative Contract," which applies to the notes, except the following disclosure which supplements, and to the extent inconsistent supersedes, the discussion in the product supplement.

Under current Internal Revenue Service guidance, withholding on "dividend equivalent" payments (as discussed in the product supplement), if any, will not apply to notes that are issued as of the date of this pricing supplement unless such notes are "delta-one" instruments. Based on our determination that the notes are not delta-one instruments, non-United States holders (as defined in the product supplement) should not generally be subject to withholding on dividend equivalent payments, if any, under the notes.

Supplemental Plan of Distribution (Conflicts of Interest)

BMOCM will purchase the notes from us at a purchase price reflecting the commission set forth on the cover hereof. BMOCM has informed us that, as part of its distribution of the notes, it will reoffer the notes to other dealers who will sell them. Each such dealer, or each additional dealer engaged by a dealer to whom BMOCM reoffers the notes, will receive a commission from BMOCM, which will not exceed the commission set forth on the cover page. We or one of our affiliates may also pay a referral fee to certain dealers in connection with the distribution of the notes. 

Certain dealers who purchase the notes for sale to certain fee-based advisory accounts may forego some or all of their selling concessions, fees or commissions. The public offering price for investors purchasing the notes in these accounts may be less than 100% of the principal amount, as set forth on the cover page of this document. Investors that hold their notes in these accounts may be charged fees by the investment advisor or manager of that account based on the amount of assets held in those accounts, including the notes. 

We will deliver the notes on a date that is greater than two business days following the pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes more than two business days prior to the issue date will be required to specify alternative settlement arrangements to prevent a failed settlement. 

We own, directly or indirectly, all of the outstanding equity securities of BMOCM, the agent for this offering. In accordance with FINRA Rule 5121, BMOCM may not make sales in this offering to any of its discretionary accounts without the prior written approval of the customer. 

We reserve the right to withdraw, cancel or modify the offering of the notes and to reject orders in whole or in part. You may cancel any order for the notes prior to its acceptance. 

You should not construe the offering of the notes as a recommendation of the merits of acquiring an investment linked to the Reference Assets or as to the suitability of an investment in the notes. 

BMOCM may, but is not obligated to, make a market in the notes. BMOCM will determine any secondary market prices that it is prepared to offer in its sole discretion. 

We may use the final pricing supplement relating to the notes in the initial sale of the notes. In addition, BMOCM or another of our affiliates may use the final pricing supplement in market-making transactions in any notes after their initial sale. Unless BMOCM or we inform you otherwise in the confirmation of sale, the final pricing supplement is being used by BMOCM in a market-making transaction.

For a period of approximately three months following issuance of the notes, the price, if any, at which we or our affiliates would be willing to buy the notes from investors, and the value that BMOCM may also publish for the notes through one or more financial information vendors and which could be indicated for the notes on any brokerage account statements, will reflect a temporary upward adjustment from our estimated value of the notes that would otherwise be determined and applicable at that time. This temporary upward adjustment represents a portion of (a) the hedging profit that we or our affiliates expect to realize over the term of the notes and (b) any underwriting discount and the selling concessions paid in connection with this offering. The amount of this temporary upward adjustment will decline to zero on a straight-line basis over the three-month period. 

The notes and the related offer to purchase notes and sale of notes under the terms and conditions provided herein do not constitute a public offering in any non-U.S. jurisdiction, and are being made available only to individually identified investors pursuant to a private offering as permitted in the relevant jurisdiction. The notes are not, and will not be, registered with any securities exchange or registry located outside of the United States and have not been registered with any non-U.S. securities or banking regulatory authority. The contents of this document have not been reviewed or approved by any non-U.S. securities or banking regulatory authority. Any person who wishes to acquire the notes from outside the United States should seek the advice or legal counsel as to the relevant requirements to acquire these notes.

British Virgin Islands. The notes have not been, and will not be, registered under the laws and regulations of the British Virgin Islands, nor has any regulatory authority in the British Virgin Islands passed comment upon or approved the accuracy or adequacy of this document. This pricing supplement and the related documents shall not constitute an offer, invitation or solicitation to any member of the public in the British Virgin Islands for the purposes of the Securities and Investment Business Act, 2010, of the British Virgin Islands.

Cayman Islands. Pursuant to the Companies Law (as amended) of the Cayman Islands, no invitation may be made to the public in the Cayman Islands to subscribe for the notes by or on behalf of the issuer unless at the time of such invitation the issuer is listed on the Cayman Islands Stock Exchange. The issuer is not presently listed on the Cayman Islands Stock Exchange and, accordingly, no invitation to the public in the Cayman Islands is to be made by the issuer (or by any dealer on its behalf). No such invitation is made to the public in the Cayman Islands hereby.

Dominican Republic. Nothing in this pricing supplement constitutes an offer of securities for sale in the Dominican Republic. The notes have not been, and will not be, registered with the Superintendence of Securities Market of the Dominican Republic (Superintendencia del Mercado de Valores), under Dominican Securities Market Law No. 249-17 (“Securities Law 249-17”), and the notes may not be offered or sold within the Dominican Republic or to, or for the account or benefit of, Dominican persons (as defined under Securities Law 249-17 and its regulations). Failure to comply with these directives may result in a violation of Securities Law 249-17 and its regulations.

Israel. This pricing supplement is intended solely for investors listed in the First Supplement of the Israeli Securities Law of 1968, as amended. A prospectus has not been prepared or filed, and will not be prepared or filed, in Israel relating to the notes offered hereunder. The notes cannot be resold in Israel other than to investors listed in the First Supplement of the Israeli Securities Law of 1968, as amended.

No action will be taken in Israel that would permit an offering of the notes or the distribution of any offering document or any other material to the public in Israel. In particular, no offering document or other material has been reviewed or approved by the Israel Securities Authority. Any material provided to an offeree in Israel may not be reproduced or used for any other purpose, nor be furnished to any other person other than those to whom copies have been provided directly by us or the selling agents.

Nothing in this pricing supplement or any other offering material relating to the notes, should be considered as the rendering of a recommendation or advice, including investment advice or investment marketing under the Law For Regulation of Investment Advice, Investment Marketing and Investment Portfolio Management, 1995, to purchase any note. The purchase of any note will be based on an investor’s own understanding, for the investor’s own benefit and for the investor’s own account and not with the aim or intention of distributing or offering to other parties. In purchasing the notes, each investor declares that it has the knowledge, expertise and experience in financial and business matters so as to be capable of evaluating the risks and merits of an investment in the notes, without relying on any of the materials provided.

Mexico. The notes have not been registered with the National Registry of Securities maintained by the Mexican National Banking and Securities Commission and may not be offered or sold publicly in Mexico. This pricing supplement and the related documents may not be publicly distributed in Mexico. The notes may only be offered in a private offering pursuant to Article 8 of the Securities Market Law.

Switzerland. The notes may not be distributed to retail investors in Switzerland. This pricing supplement shall not be dispatched, copied to or otherwise made available to any person in Switzerland, and the notes may not be offered for sale to any person in Switzerland, except in accordance with Swiss law.

The notes are not offered, sold or advertised, directly or indirectly, in, into or from Switzerland on the basis of a public offering and will not be listed on the SIX Swiss Exchange or any other offering or regulated trading facility in Switzerland. Accordingly, neither this pricing supplement or any other marketing material constitute a prospectus as defined in article 652a or article 1156 of the Swiss Code of Obligations or a listing prospectus as defined in article 32 of the Listing Rules of the SIX Swiss Exchange or any other regulated trading facility in Switzerland. Any sales or resales of the notes may only be undertaken on a private basis to selected individual investors in compliance with Swiss law. By accepting this pricing supplement or by purchasing the notes, investors are deemed to have acknowledged and agreed to abide by these restrictions.

The notes may also be sold in the following jurisdictions, provided, in each case, any sales are made in accordance with all applicable laws in such jurisdiction:

Additional Information Relating to the Estimated Initial Value of the Notes

Our estimated initial value of the notes on the date hereof, and that will be set forth on the cover page of the final pricing supplement relating to the notes, equals the sum of the values of the following hypothetical components:

The internal funding rate used in the determination of the initial estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. The value of these derivative transactions is derived from our internal pricing models. These models are based on factors such as the traded market prices of comparable derivative instruments and on other inputs, which include volatility, dividend rates, interest rates and other factors. As a result, the estimated initial value of the notes on the Pricing Date will be determined based on the market conditions on the Pricing Date. 

The Reference Assets

The Utilities Select Sector SPDR^® Fund (“XLU”)

The Utilities Select Sector SPDR^® Fund (the “XLU”) is an investment portfolio managed by SSgA Funds Management, Inc. (“SSFM”), the investment adviser to the XLU. The XLU is an exchange-traded fund that trades on the NYSE Arca, Inc. ("NYSE Arca") under the ticker symbol “XLU.”

Information provided to or filed with the SEC by the Select Sector SPDR^® Trust pursuant to the Securities Act and the Investment Company Act 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.

Investment Objective

The XLU seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of publicly traded equity securities of companies in the utilities sector, as represented by the Utilities Select Sector Index (the “IXU”). The IXU measures the performance of the utilities sector of the U.S. equity market and includes companies in the following industries: electric utilities; water utilities; multi-utilities; independent power producers and energy traders; and gas utilities. The returns of the XLU may be affected by certain management fees and other expenses, which are detailed in its prospectus.

Investment Strategy — Replication

The XLU pursues the indexing strategy of “replication” in attempting to approximate the performance of IXU. The XLU will generally invest in substantially all of the equity securities included in the IXU in approximately the same proportions as the IXU. There may, however, be instances where SSFM may choose to overweight another stock in the IXU, purchase securities not included in the IXU that SSFM believes are appropriate to substitute for a security included in the IXU or utilize various combinations of other available investment techniques in seeking to track accurately the IXU. The XLU will normally invest at least 95% of its total assets in common stocks that comprise the IXU. The XLU  may invest its remaining assets in money market instruments (including repurchase contracts). Swaps, options and futures contracts (and convertible securities and structured notes) may be used by the XLU in seeking performance that corresponds to the IXU and managing cash flows. SSFM anticipates that, under normal circumstances, it may take several business days for additions and deletions to the SPX to be reflected in the portfolio composition of the XLU. The Board of Trustees of the Select Sector SPDR^® Trust may change the XLU’s investment strategy and other policies without shareholder approval.

Correlation

 The IXU is a theoretical financial calculation, while the XLU is an actual investment portfolio. The performance of the XLU and the IXU will vary somewhat due to transaction costs, asset valuations, market impact, corporate actions (such as mergers and spin-offs) and timing variances. A figure of 100% would indicate perfect correlation. Any correlation of less than 100% is called “tracking error.” The XLU, using a replication strategy, can be expected to have a lesser tracking error than a fund using representative sampling strategy. Representative sampling is a strategy in which a fund invests in a representative sample of securities in a tracking index.

The Utilities Select Sector Index

The IXU is a modified market capitalization-based index, intended to provide an indication of the pattern of common stock price movements of companies that are components of the SPX and are involved in the utilities industry. The IXU is one of the eleven Select Sector sub-indices of the SPX, each of which we refer to as a “Select Sector Index.”

The Index is also sponsored and compiled by S&P DJI. S&P DJI determines the composition of the Index and relative weightings of the securities in the Index based on the Index methodology (as the “Index Compilation Agent”). S&P DJI also publishes information regarding the market value of the Index (as the “Index Provider”). S&P DJI is not affiliated with the Fund or the Adviser. The composition and weighting of the stocks included in the IXU will likely differ from the composition and weighting of stocks included in any similar Select Sector Index that is published and disseminated by S&P. S&P’s only relationship to the Index Compilation Agent is the licensing of certain trademarks and trade names of S&P and of the SPX which is determined, composed and calculated by S&P without regard to the Index Compilation Agent.

The Select Sector Indices

Construction, Maintenance and Calculation of The Select Sector Indices:

 The Select Sector Index is developed and maintained in accordance with the following criteria:

This occurs at the closing prices of the second Friday of March, June, September and December and becomes effective after the market close on the third Friday of March, June, September and December.

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 investable weight factors as of the rebalancing effective date.

The Index Compilation Agent at any time may determine that a Component Stock which has been assigned to one Select Sector Index has undergone such a transformation in the composition of its business that it should be removed from that Select Sector Index and assigned to a different Select Sector Index. In the event that the Index Compilation Agent notifies the index calculation agent that a Component Stock’s Select Sector Index assignment should be changed, the index calculation agent will disseminate notice of the change following its standard procedure for announcing index changes and will implement the change in the affected Select Sector Indices on a date no less than one week after the initial dissemination of information on the sector change to the maximum extent practicable. It is not anticipated that Component Stocks will change sectors frequently. Component Stocks removed from and added to the SPX will be deleted from and added to the appropriate Select Sector Index on the same schedule used by S&P for additions and deletions from the SPX insofar as practicable.

The Russell 2000^® Index (“RTY”)

The Russell 2000^® Index was developed by Russell Investments (“Russell”) before FTSE International Limited (“FTSE”) and Russell combined in 2015 to create FTSE Russell, which is wholly owned by London Stock Exchange Group. Russell began dissemination of the Russell 2000^® Index (Bloomberg L.P. index symbol “RTY”) on January 1, 1984. The Russell 2000^® Index was set to 135 as of the close of business on December 31, 1986. FTSE Russell calculates and publishes the Russell 2000^® Index. The Russell 2000^® Index is designed to track the performance of the small capitalization segment of the U.S. equity market. The Russell 2000^® Index is a subset of the Russell 3000^® Index representing approximately 10% of the total market capitalization of that index. It includes approximately 2,000 of the smallest securities based on a combination of their market cap and current index membership. The Russell 3000^® Index measures the performance of the largest 3,000 U.S. companies. The Russell 2000^® Index is determined, comprised, and calculated by FTSE Russell without regard to the notes.

Selection of Stocks Comprising the Russell 2000^® Index

All companies eligible for inclusion in the Russell 2000^® Index must be classified as a U.S. company under FTSE Russell’s country-assignment methodology. If a company is incorporated, has a stated headquarters location, and trades on a standard exchange in the same country (American Depositary Receipts and American Depositary Shares are not eligible), then the company is assigned to its country of incorporation. If any of the three factors are not the same, FTSE Russell defines three Home Country Indicators (“HCIs”): country of incorporation, country of headquarters, and country of the most liquid exchange as defined by a two-year average daily dollar trading volume (“ADDTV”) from all exchanges within a country. Using the HCIs, FTSE Russell cross-compares the primary location of the company’s assets with the three HCIs. If the primary location of its assets matches any of the HCIs, then the company is assigned to its primary asset location. If there is insufficient information to determine located company’s primary location of assets, FTSE Russell will use 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 revenues data for analysis to reduce potential turnover. If conclusive country details cannot be derived from assets or revenues data, FTSE Russell will assign 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, the company is assigned to the country of its most liquid stock exchange. BDI countries include: 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. For any companies incorporated or headquartered in a U.S. territory, including countries such as Puerto Rico, Guam, and U.S. Virgin Islands, a U.S. HCI is assigned. “N-Shares” of companies controlled by entities in mainland China are not eligible for inclusion in the Russell 2000^® Index.

All securities eligible for inclusion in the Russell 2000^® Index must trade on an eligible U.S. exchange. Stocks must have a closing price at or above $1.00 (on its primary exchange) on rank day in May of each year (timetable is announced each spring) to be eligible for inclusion during annual reconstitution. However, in order to reduce unnecessary turnover, if an existing member’s closing price is less than $1.00 on rank day of May, it will be considered eligible if the average of the daily closing prices (from its primary exchange) during the 30 days prior to the rank date is equal to or greater than $1.00. FTSE Russell adds initial public offerings (IPOs) each quarter to ensure that new additions to the institutional investing opportunity set are reflected in representative indexes. A stock added during the quarterly IPO process is considered a new index addition, and therefore must have a closing price on its primary exchange at or above $1.00 on the last day of the eligibility period in order to qualify for index inclusion. If an existing index member does not trade on the rank day, it must price at $1.00 or above on another eligible U.S. exchange to remain eligible.

Royalty trusts, U.S. limited liability companies, closed-end investment companies (companies that are required to report Acquired Fund Fees and Expenses, as defined by the SEC, including business development companies, are not eligible for inclusion), blank check companies, special-purpose acquisition companies (SPACs), Exchange Traded Funds (ETFs), mutual funds and limited partnerships are ineligible for inclusion. Preferred and convertible preferred stock, redeemable shares, participating preferred stock, warrants, rights, depositary receipts, installment receipts and trust receipts are not eligible for inclusion in the Russell 2000^® Index.

Annual reconstitution is a process by which the Russell 2000^® Index is completely rebuilt. On the rank day in May of each year, all eligible securities are ranked by their total market capitalization. The largest 4,000 become the Russell 3000E Index, and the other FTSE Russell indexes are determined from that set of securities. If there are not 4, 000 eligible securities in the U.S. market, the entire eligible set is include. Reconstitution of the Russell 2000^® Index occurs on the last Friday in June or, when the last Friday in June is the 29th or 30th, reconstitution occurs on the prior Friday. In addition, FTSE Russell adds initial public offerings to the Russell 2000^® Index on a quarterly basis based on total market capitalization ranking within the market-adjusted capitalization breaks established during the most recent reconstitution.

After membership is determined, a security’s shares are adjusted to include only those shares available to the public. This is often referred to as “free float.” The purpose of the adjustment is to exclude from market calculations the capitalization that is not available for purchase and is not part of the investable opportunity set.
