These documents may be obtained without cost by visiting EDGAR on the SECWebsite at www.sec.gov. Alternatively, Bank of Montreal, any agent or any dealer participating in this offering will arrange to send the pricing supplement, the prospectussupplement and the prospectus if so requested by calling toll-free at 1-877-369-5412.The ETNs are senior, unsecured debt obligations of Bank of Montreal and are subject to Bank of Montreal’s credit risk.Investment suitability must be determined individually for each investor, and the ETNs may not be suitable for all investors. This information is not intended to provideand should not be relied upon as providing accounting, legal, regulatory or tax advice. Investors should consult with their own financial advisors as to these matters.The ETNs are intended to be daily trading tools for sophisticated investors to manage daily trading risks as part of an overall diversified portfolio. They are designedto achieve their stated investment objectives on a daily basis. You should proceed with extreme caution in considering an investment in the ETNs.The ETNs do not guarantee the return of your investment. If the Intraday Indicative Value for the ETNs is equal to or less than $0 at any time during an Exchange BusinessDay or the Indicative Note Value is equal to or less than $0, you will lose all of your investment in the ETNs. Even if the Index Closing Level has decreased from the InitialIndex Level, you may receive less than the principal amount of your ETNs upon a call, redemption, at maturity, or if you sell your ETNs, as described more in the pricingsupplement.The ETNs are not suitable for investors with longer-term investment objectives. In particular, the ETNs should be purchased only by sophisticated investors who do notintend to hold the ETNs as a buy and hold investment, who are willing to actively and continuously monitor their investment and who understand the consequences ofinvesting in and of seeking daily resetting investment results. Due to the effect of compounding, if the Indicative Note Value increases, any subsequent increase of theIndex level will result in a larger dollar reduction from the Indicative Note Value than if the Indicative Note Value remained constant; the converse is also true. The ETNsare subject to intraday purchase risk. The Indicative Note Value is reset daily, and the exposure of the ETNs during any given Exchange Business Day may be greater thanor less than negative one.The ETNs are subject to a call right, which may adversely affect the value of, or your ability to sell, your ETNs. The ETNs do not pay any interest, and you will not haveany ownership rights in the Index constituents. The Index Closing Level used to calculate any payment by the Issuer of the ETNs may be less than the Index ClosingLevel at other times during the term of the ETNs. There are restrictions on your ability to request a redemption of the ETNs, and you will not know the amount due uponredemption at the time you elect to request that the ETNs be redeemed. The Issuer may sell additional ETNs but is under no obligation to do so.Market disruptions may adversely affect your return. Significant aspects of the tax treatment of the ETNs are uncertain.The Intraday Indicative Value and the Indicative Note Value are not the same as the closing price or any other trading price of the ETNs in the secondary market. There isno assurance that your ETNs will be listed or continue to be listed on a securities exchange, and they may not have an active trading market. The value of the ETNs in thesecondary market may be influenced by many unpredictable factors.The Issuer or its affiliates may have economic interests that are adverse to those of the holders of the ETNs as a result of our business, hedging and trading activities, oras Calculation Agent of the ETNs, and may have published research, expressed opinions or provided recommendations that are inconsistent with investing in or holdingthe ETNs, and may do so in the future.The Index has limited actual historical information. The Index Calculation Agent may adjust the Index in a way that may affect its level, and may, in its sole discretion,discontinue the public disclosure of the intraday Index value and the end-of-day closing value of the Index. The Index lacks diversification and is vulnerable to fluctuationsin the technology and consumer discretionary industries. A limited number of Index constituents may affect the Index Closing Level, and the Index is not necessarilyrepresentative of its focus industry. An Index constituent may be replaced upon the occurrence of certain adverse events. The Index uses a proprietary selectionmethodology, which may not select the constituent issuers in the same manner as would other index providers or market participants.Use of Hypothetical Back-Tested Data — The historical data of the Index shown herein is from September 26, 2017.
