Market-Linked Step Up Notes Linked to an International Equity Index Basket, due October 25, 2019

The Market-Linked Step Up Notes Linked to an International Equity Index Basket, due October 25, 2019 (the "notes") are our senior unsecured debt securities. The notes are not guaranteed or insured by the CDIC or the FDIC, and are not, either directly or indirectly, an obligation of any third party. The notes will rank equally with all of our other unsecured senior debt. Any payments due on the notes, including any repayment of principal, will be subject to the credit risk of BNS. The notes provide you with a Step Up Payment if the Ending Value of the Market Measure, which is the international equity index basket described below (the "Basket"), is equal to or greater than the Starting Value, but not greater than the Step Up Value. If the Ending Value is greater than the Step Up Value, you will participate on a 1-for-1 basis in the increase in the level of the Basket above the Starting Value. If the Ending Value is less than the Starting Value, you will lose all or a portion of the principal amount of your notes. Any payments on the notes will be calculated based on the $10 principal amount per unit and will depend on the performance of the Basket, subject to our credit risk. See "Terms of the Notes" below.

The Basket is comprised of the EURO STOXX 50^® Index, the MSCI Emerging Markets Index, and the JPX-Nikkei Index 400 (each a “Basket Component”). On the pricing date, the EURO STOXX 50^® Index was given an initial weight of 60%, and each of the MSCI Emerging Markets Index and the JPX-Nikkei Index 400 was given an initial weight of 20%.

The economic terms of the notes (including the Step Up Payment) are based on our internal funding rate, which is the rate we would pay to borrow funds through the issuance of market-linked notes, and the economic terms of certain related hedging arrangements.  Our internal funding rate is typically lower than the rate we would pay when we issue conventional fixed rate debt securities. This difference in funding rate, as well as the underwriting discount and the hedging related charge described below, reduced the economic terms of the notes to you and the initial estimated value of the notes on the pricing date. Due to these factors, the public offering price you pay to purchase the notes is greater than the initial estimated value of the notes.

On the cover page of this term sheet, we have provided the initial estimated value for the notes. This estimated value was determined by reference to our internal pricing models, which take into consideration certain factors, such as our internal funding rate on the pricing date and our assumptions about market parameters. For more information about the initial estimated value and the structuring of the notes, see “Structuring the Notes” on page TS-18.

§	Depending on the performance of the Basket as measured shortly before the maturity date, your investment may result in a loss; there is no guaranteed return of principal.

 

§	Your return on the notes may be less than the yield you could earn by owning a conventional fixed or floating rate debt security of comparable maturity.

 

§	Your investment return may be less than a comparable investment directly in the stocks included in the Basket Components.

 

§	Payments on the notes are subject to our credit risk, and actual or perceived changes in our creditworthiness are expected to affect the value of the notes. If we become insolvent or are unable to pay our obligations, you may lose your entire investment.

 

§

Our initial estimated value of the notes is lower than the public offering price of the notes. Our initial estimated value of the notes is only an estimate. The public offering price of the notes exceeds our initial estimated value because it includes costs associated with selling and structuring the notes, as well as hedging our obligations under the notes with a third party, which may include MLPF&S or one of its affiliates. These costs include the underwriting discount and an expected hedging related charge, as further described in "Structuring the Notes" on page TS-18.

 

§

Our initial estimated value of the notes does not represent future values of the notes and may differ from others’ estimates. Our initial estimated value of the notes is determined by reference to our internal pricing models when the terms of the notes are set.  These pricing models consider certain factors, such as our internal funding rate on the pricing date, the expected term of the notes, market conditions and other relevant factors existing at that time, and our assumptions about market parameters, which can include volatility, dividend rates, interest rates and other factors.  Different pricing models and assumptions could provide valuations for the notes that are different from our initial estimated value. In addition, market conditions and other relevant factors in the future may change, and any of our assumptions may prove to be incorrect. On future dates, the market value of the notes could change significantly based on, among other things, the performance of the Basket, changes in market conditions, our creditworthiness, interest rate movements and other relevant factors.  These factors, together with various credit, market and economic factors over the term of the notes, are expected to reduce the price at which you may be able to sell the notes in any secondary market and will affect the value of the notes in complex and unpredictable ways. Our initial estimated value does not represent a minimum price at which we or any agents would be willing to buy your notes in any secondary market (if any exists) at any time.

 

§

Our initial estimated value is not determined by reference to credit spreads or the borrowing rate we would pay for our conventional fixed-rate debt securities. The internal funding rate used in the determination of our initial estimated value of the notes generally represents a discount from the credit spreads for our conventional fixed-rate debt securities and the borrowing rate we would pay for our conventional fixed-rate debt securities. If we were to use the interest rate implied by the credit spreads for our conventional fixed-rate debt securities, or the borrowing rate we would pay for our conventional fixed-rate debt securities, we would expect the economic terms of the notes to be more favorable to you. Consequently, our use of an internal funding rate for the notes would have an adverse effect on the economic terms of the notes, the initial estimated value of the notes on the pricing date, and the price at which you may be able to sell the notes in any secondary market.

 

§	A trading market is not expected to develop for the notes. Neither we nor MLPF&S is obligated to make a market for, or to repurchase, the notes. There is no assurance that any party will be willing to purchase your notes at any price in any secondary market.

 

§

Our business, hedging and trading activities, and those of MLPF&S and our respective affiliates (including trades in shares of companies included in the Basket Components), and any hedging and trading activities we, MLPF&S or our respective affiliates engage in for our clients’ accounts, may affect the market value and return of the notes and may create conflicts of interest with you.

 

§

Changes in the level of one of the Basket Components may be offset by changes in the levels of the other Basket Components.  Due to the different Initial Component Weights (as defined in “The Basket” section below), changes in the level of the EURO STOXX 50® Index will have a more substantial impact on the value of the Basket than similar changes in the levels of the other Basket Components.

 

§	An index sponsor may adjust the relevant Basket Component in a way that may adversely affect its level and your interests, and has no obligation to consider your interests.

 

§	You will have no rights of a holder of the securities included in the Basket Components, and you will not be entitled to receive securities or dividends or other distributions by the issuers of those securities.

§	Your return on the notes and the value of the notes may be affected by relevant exchange rate movements and factors affecting the international securities markets, specifically changes in the countries represented by the Basket Components.

 

§	There may be potential conflicts of interest involving the calculation agent, which is MLPF&S. We have the right to appoint and remove the calculation agent.

 

§	The U.S. federal income tax consequences of the notes are uncertain, and may be adverse to a holder of the notes.  See “Summary of U.S. Federal Income Tax Consequences” below.

 

§

The conclusion that no portion of the interest paid or credited or deemed to be paid or credited on a note will be “Participating Debt Interest” subject to Canadian withholding tax is based in part on the current published administrative position of the CRA.  There cannot be any assurance that CRA’s current published administrative practice will not be subject to change, including potential expansion in the current administrative interpretation of Participating Debt Interest subject to Canadian withholding tax.  If, at any time, the interest paid or credited or deemed to be paid or credited on a note is subject to Canadian withholding tax, you will receive an amount that is less than the Redemption Amount. You should consult your own adviser as to the potential for such withholding and the potential for reduction or refund of part or all of such withholding, including under any bilateral Canadian tax treaty the benefits of which you may be entitled. For a discussion of the Canadian federal income tax consequences of investing in the notes, see “Summary of Canadian Federal Income Tax Consequences” below, “Canadian Taxation—Debt Securities” on page 50 of the prospectus dated February 1, 2017, and “Supplemental Discussion of Canadian Federal Income Tax Consequences” on page PS-29 of product prospectus supplement EQUITY INDICES SUN-1.

The EURO STOXX 50^® Index

The SX5E is a capitalization-weighted index of 50 European blue-chip stocks in 11 Eurozone countries. Publication of the SX5E began on February 26, 1998, based on an initial index value of 1,000 at December 31, 1991. The level of the SX5E is disseminated on, and additional information about the SX5E is published on, the STOXX website. Information contained in the STOXX website is not incorporated by reference in, and should not be considered a part of, this term sheet.

As of September 29, 2017, the top ten industry sectors which comprise the SX5E represent the following weights in the SX5E: Banks (16.1%), Industrial Goods & Services (10.5%), Chemicals (9.1%), Personal & Household Goods (9.0%), Health Care (7.4%), Technology (7.3%), Insurance (6.8%), Oil & Gas (6.1%), Utilities (5.1%) and Telecommunications (4.9%). As of September 29, 2017, the eight countries which comprise the SX5E represent the following weights therein: France (36.2%), Germany (32.9%), Spain (10.6%), Netherlands (10.1%), Italy (4.8%), Belgium (3.1%), Finland (1.2%) and Ireland (1.1%).

Index Composition and Maintenance

For each of the 19 EURO STOXX regional supersector indices, the stocks are ranked in terms of free-float market capitalization. The largest stocks are added to the selection list until the coverage is close to, but still less than, 60% of the free-float market capitalization of the corresponding supersector index. If the next highest-ranked stock brings the coverage closer to 60% in absolute terms, then it is also added to the selection list. All current stocks in the SX5E are then added to the selection list. All of the stocks on the selection list are then ranked in terms of free-float market capitalization to produce the final index selection list. The largest 40 stocks on the selection list are selected; 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. In exceptional cases, STOXX’s management board can add stocks to and remove them from the selection list.

The SX5E components are subject to a capped maximum index weight of 10%, which is applied on a quarterly basis.

The composition of the SX5E is reviewed annually, based on the closing stock data on the last trading day in August. Changes in the composition of the SX5E are made to ensure that the SX5E includes the 50 market sector leaders from within the SX5E.

The SX5E is subject to a “fast exit rule.” The SX5E components are monitored for any changes based on the monthly selection list ranking. A stock is deleted from the SX5E if: (a) it ranks 75 or below on the monthly selection list and (b) it ranked 75 or below on the selection list of the previous month. The highest-ranked stock that is not an Index component will replace it. Changes will be implemented on the close of the fifth trading day of the month, and are effective the next trading day.

The SX5E is also subject to a “fast entry rule.” All stocks on the latest selection lists and initial public offering (IPO) stocks are reviewed for a fast-track addition on a quarterly basis. A stock is added, if (a) it qualifies for the latest STOXX blue-chip selection list generated at the end of February, May, August or November and (b) it ranks within the “lower buffer” (ranks 1-25) on this selection list.

The SX5E is also reviewed on an ongoing basis. Corporate actions (including initial public offerings, mergers and takeovers, spin-offs, delistings, and bankruptcy) that affect the SX5E 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.

Index Calculation

The SX5E 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 SX5E value can be expressed as follows:

Index = free float market capitalization of the Index at the time

divisor of the Index at the time

The “free float market capitalization of the index” is equal to the sum of the products of the closing price, number of shares, free float factor, and weighting cap factor for the component company as of the time that the SX5E is being calculated.

 

The SX5E is calculated using a divisor that helps to maintain the continuity of the SX5E’s value so that corporate actions do not artificially increase or decrease the level of the SX5E.  The divisor of the SX5E is adjusted to maintain the continuity of the SX5E’s values across changes due to corporate actions, such as cash dividends, rights offerings, stock dividends from treasury shares, repurchases of shares and self-tender, and spin-offs.

The MSCI Emerging Markets Index

The MSCI indices were founded in 1969 by Capital International as the first international performance benchmarks constructed to facilitate accurate comparison of world markets.  Morgan Stanley acquired the rights to license the MSCI indices in 1986.  In November 1998, Morgan Stanley transferred all rights to the MSCI indices to MSCI, a Delaware corporation formed and operated jointly by Morgan Stanley and Capital International.  In 2004, MSCI acquired Barra, Inc., a provider of risk analytics, and firm-wide investment risk management systems and services and merged this with MSCI. In 2007, MSCI completed an initial public offering and was listed on the New York Stock Exchange, with Morgan Stanley retaining a controlling interest. In 2009, MSCI and Morgan Stanley fully separated. The MSCI single country standard equity indices have covered the world’s developed markets since 1969, and in 1988, MSCI commenced coverage of the emerging markets.

All information regarding the index reflects the policies of, and is subject to change by, MSCI. 

The MXEF offers a representation of emerging markets based on the following countries: Brazil, Chile, China, Colombia, the Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Malaysia, Mexico, Pakistan, Peru, the Philippines, Poland, Qatar, Russia, South Africa, Taiwan, Thailand, Turkey and the United Arab Emirates. With 839 constituents, the MXEF covers approximately 85% of the free float-adjusted market capitalization in each country. It is based on the Global Investable Market Indices methodology which emphasizes index liquidity, investibility and replicability. The MXEF has a base value of 100.00 and a base date of December 31, 1987.

The Country Indices

The components of each MSCI EM Constituent Country Index used to be selected by MSCI from among the universe of securities eligible for inclusion in the MSCI EM Constituent Country Index so as to target an 85% free float-adjusted market representation level within each of a number of industry groups, subject to adjustments to (i) provide for sufficient liquidity, (ii) reflect foreign investment restrictions (only those securities that can be held by non-residents of the country corresponding to the relevant MSCI EM Constituent Country Index are included) and (iii) meet certain other investibility criteria. Following a change in MSCI’s methodology implemented in May 2008, the 85% target is now measured at the level of the country universe of eligible securities rather than the industry group level—so each MSCI EM Constituent Country Index will seek to include the securities that represent 85% of the free float-adjusted market capitalization of all securities eligible for inclusion—but will still be subject to liquidity, foreign investment restrictions and other investibility adjustments.  MSCI defines “free float” as total shares excluding shares held by strategic investors such as governments, corporations, controlling shareholders and management, and shares subject to foreign ownership restrictions.

Calculation of the MSCI EM Constituent Country Indices

Each MSCI EM Constituent Country Index is a free float-adjusted market capitalization index that is designed to measure the market performance, including price performance, of the equity securities in that country. Each MSCI EM Constituent Country Index is calculated in the relevant local currency as well as in U.S. dollars, with price, gross and net returns.

Each component is included in the relevant MSCI EM Constituent Country Index at a weight that reflects the ratio of its free float-adjusted market capitalization (i.e., free public float multiplied by price) to the free float-adjusted market capitalization of all the components in that MSCI EM Constituent Country Index. MSCI defines the free float of a security as the proportion of shares outstanding that is deemed to be available for purchase in the public equity markets by international investors.

Calculation of the MXEF

The performance of the MXEF on any given day represents the weighted performance of all of the components included in all of the MSCI EM Constituent Country Indices.  Each component in the MXEF is included at a weight that reflects the ratio of its free float-adjusted market capitalization (i.e., free public float multiplied by price) to the free float-adjusted market capitalization of all the components included in all of the MSCI EM Constituent Country Indices.

Maintenance of and Changes to the MXEF

MSCI maintains the MXEF with the objective of reflecting, on a timely basis, the evolution of the underlying equity markets and segments.  In maintaining the MXEF, emphasis is also placed on continuity, continuous investibility of constituents, replicability, index stability and low turnover in the MXEF.

As part of the changes to MSCI’s methodology which became effective in May 2008, maintenance of the indices falls into three broad categories:

·	semi-annual reviews, which will occur each May and November and will involve a comprehensive reevaluation of the market, the universe of eligible securities and other factors involved in composing the MXEF;

·	quarterly reviews, which will occur each February, May, August and November and will focus on significant changes in the market since the last semi-annual review and on including significant new eligible securities (such as IPOs, which were not eligible for earlier inclusion in the MXEF); and

·	ongoing event-related changes, which will generally be reflected in the indices at the time of the event and will include changes resulting from mergers, acquisitions, spin-offs, bankruptcies, reorganizations and other similar corporate events.

Based on these reviews, additional components may be added, and current components may be removed, at any time.  MSCI generally announces all changes resulting from semi-annual reviews, quarterly reviews and ongoing events in advance of their implementation, although in exceptional cases they may be announced during market hours for same or next day implementation.

The prices used to calculate the MXEF are the official exchange closing prices or those figures accepted as such.  MSCI reserves the right to use an alternative pricing source on any given day.

Exchange Rates

MSCI uses the closing spot rates published by WM / Reuters at 4:00 p.m., London time. MSCI uses WM / Reuters rates for all countries for which it provides indices.

In case WM/Reuters does not provide rates for specific markets on given days (for example Christmas Day and New Year’s Day), the previous business day’s rates are normally used. MSCI independently monitors the exchange rates on all its indices and may, under exceptional circumstances, elect to use an alternative exchange rate if the WM / Reuters rates are not available, or if MSCI determines that the WM / Reuters rates are not reflective of market circumstances for a given currency on a particular day.  In such circumstances, an announcement would be sent to clients with the related information.  If appropriate, MSCI may conduct a consultation with the investment community to gather feedback on the most relevant exchange rate.

The following graph shows the daily historical performance of the MXEF in the period from January 1, 2008 through October 26, 2017. We obtained this historical data from Bloomberg L.P.  We have not independently verified the accuracy or completeness of the information obtained from Bloomberg L.P. On the pricing date, the closing level of the MXEF was 1,108.17.

Historical Performance of the MSCI Emerging Markets Index

The JPNK400 is composed of stocks listed on the TSE’s First Section (large companies), Second Section (mid-size companies), Mothers (Market Of The High-growth and Emerging Stocks) and NASDAQ market.  Stocks included in the JPNK400 are selected based on market capitalization, trading value, return on equity and other factors, as described in more detail below.  The JPNK400 was first calculated and published on January 6, 2014.  The inception value of the JPNK400 was 10,000 on August 30, 2013 (the calculation base date). The JPNK400 is calculated every one second during the trading hours of the TSE.

Ten main groups of companies are included in the JPNK400, with the approximate percentage of the market capitalization of the JPNK400 included in each group as of December 30, 2016 indicated in parentheses: Commercial & Wholesale Trade (4.69%); Machinery (5.21%); Pharmaceutical (5.91%); Transportation & Logistics (5.98%); Financials (excluding banks) (6.52%); Raw Materials & Chemicals (7.66%); Banks (8.38%); Automobiles & Transportation Equipment (9.96%); IT & Services (10.40%); Electric Appliances & Precision Instruments (15.02%) and Others (20.27%). As of that date, 395 of the securities included in the JPNK400 were listed on the TSE’s First Section.

The notes are linked to the price return version of the JPNK400 and is calculated in yen, which means (as noted above) that the Ending Value will not include any income generated by dividends paid on the stocks included in the JPNK400.

Additional information relating to the composition and calculation of the JPNK400 is available on the JPNK400 sponsor’s website:  http://www.jpx.co.jp/english/markets/indices/jpx-nikkei400/. However, information included in that website shall not be deemed to be included or incorporated by reference in this document.

Standards for Listing and Maintenance

The JPNK400 components are reviewed annually based on the selection criteria applied as of the final business day of June (the base selection date). The calculation of the JPNK400 using the new constituents will begin from the last business day of August.  The selection process and criteria are as follows:

(1)  1,000 stocks are selected based on their trading value over the past three years and the market value on the base selection date.  Stocks are excluded from selection if they fall under any of the following criteria:

·	listed for less than three years;

·	the company’s liabilities are in excess of its assets during any of the past three fiscal years;

·	the company has an operating loss in each of the past three fiscal years;

·	the company has a net loss in each of the past three fiscal years;

·	the company’s financials have disclosed doubt regarding its ability to continue as a going concern;

·	disclosure of insufficient financials controls;

·	the stock has been designated as a security to be delisted or security on alert; or

·	certain listing violations have occurred over the past year.

(2)  Each stock is scored by (a) three-year average return on equity (weighted 40%), (b) three-year cumulative operating profit (weighted 40%) and (c) market capitalization on the base selection date (weighted 20%), determined as follows:

Three-year average return on equity is calculated as follows:

Three-year cumulative operating profit is the sum of reported operating profit over the past three years.

The market capitalization of a stock is calculated based on the number of listed shares multiplied by its closing share price as of the annual base selection date.

 

(3)  400 stocks are selected by the final ranking with the scores calculated above in (2) and qualitative factors from the perspectives of corporate governance and disclosure.  These factors are applied as of the base selection date and include the appointment of at least two independent outside directors, releasing the most recent earnings report according to international financial reporting standards and the release of English language earnings information via TDnet (Timely Disclosure Network).  The final score for each stock equals the sum of the score calculated above in (2) plus the score from the qualitative factors.  Stocks are ranked from highest to lowest based on their final scores, with the exception that stocks with negative three-year average return on equity and most recent return on equity are negative or that have negative three-year cumulative operating profit are moved to the bottom of the ranking.  In the event of a tie in final scores, the stock with the higher market capitalization is ranked higher.

review. In case of delisting of the components due to a merger, bankruptcy, or other corporate event, new stocks are not added until the next annual review.

The free-float adjustment market value is determined by excluding the estimated number of listed shares that are deemed not to be available for trading in the market, using publicly available documents. Among the shares that are not treated as available are, among others, shares held by specified types of major shareholders, and shares held by board members and other representatives. The free-float weights are reviewed annually for each stock included in the JPNK400, with the announcement and effective date for each stock included in the JPNK400 occurring on a quarterly basis, depending upon the relevant company’s earnings release schedule. In addition to this annual review, the JPNK400 sponsor may also adjust a company’s free-float weight to reflect extraordinary events.

The stocks included in the JPNK400 can be updated from time to time to reflect, for example, the establishment of a new company as a result of a corporate consolidation, or the delisting of a company.  A variety of corporate events will result in the change of the number of shares used to calculate the JPNK400, including securities offerings, exercises of warrants and share dividends.

The following graph shows the daily historical performance of the JPNK400 in the period from January 6, 2014 through October 26, 2017. This index was first published on January 6, 2014, thus only limited historical information exists with respect to it. We obtained this historical data from Bloomberg L.P.  We have not independently verified the accuracy or completeness of the information obtained from Bloomberg L.P. On the pricing date, the closing level of the JPNK400 was 15,533.24.

Historical Performance of the JPX-Nikkei Index 400

This historical data on the JPNK400 is not necessarily indicative of the future performance of the JPNK400 or what the value of the notes may be. Any historical upward or downward trend in the level of the JPNK400 during any period set forth above is not an indication that the level of the JPNK400 is more or less likely to increase or decrease at any time over the term of the notes.

Market-Linked Step Up Notes Linked to an International Equity Index Basket, due October 25, 2019

Under our distribution agreement with MLPF&S, MLPF&S will purchase the notes from us as principal at the public offering price indicated on the cover of this term sheet, less the indicated underwriting discount.

We will deliver the notes against payment therefor in New York, New York 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, 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 original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

The notes will not be listed on any securities exchange. In the original offering of the notes, the notes will be sold in minimum investment amounts of 100 units. If you place an order to purchase the notes, you are consenting to MLPF&S acting as a principal in effecting the transaction for your account.

MLPF&S may repurchase and resell the notes, with repurchases and resales being made at prices related to then-prevailing market prices or at negotiated prices, and these prices will include MLPF&S’s trading commissions and mark-ups. MLPF&S may act as principal or agent in these market-making transactions; however, it is not obligated to engage in any such transactions. At MLPF&S’s discretion, for a short, undetermined initial period after the issuance of the notes, MLPF&S may offer to buy the notes in the secondary market at a price that may exceed the initial estimated value of the notes. Any price offered by MLPF&S for the notes will be based on then-prevailing market conditions and other considerations, including the performance of the Basket and the remaining term of the notes. However, none of us, MLPF&S, or any of our respective affiliates is obligated to purchase your notes at any price or at any time, and we cannot assure you that we, MLPF&S or any of our respective affiliates will purchase your notes at a price that equals or exceeds the initial estimated value of the notes.

The value of the notes shown on your account statement produced by MLPF&S will be based on MLPF&S’s estimate of the value of the notes if MLPF&S or another of its affiliates were to make a market in the notes, which it is not obligated to do. That estimate will be based upon the price that MLPF&S may pay for the notes in light of then-prevailing market conditions, and other considerations, as mentioned above, and will include transaction costs. At certain times, this price may be higher than or lower than the initial estimated value of the notes.

The distribution of the Note Prospectus in connection with these offers or sales will be solely for the purpose of providing investors with the description of the terms of the notes that was made available to investors in connection with their initial offering. Secondary market investors should not, and will not be authorized to, rely on the Note Prospectus for information regarding BNS or for any purpose other than that described in the immediately preceding sentence.

The notes are our unsecured senior debt securities, the return on which is linked to the performance of the Basket.  As is the case for all of our debt securities, including our market-linked notes, the economic terms of the notes reflect our actual or perceived creditworthiness at the time of pricing. The internal funding rate we use in pricing the market-linked note is typically lower than the rate we would pay when we issue conventional fixed-rate debt securities of comparable maturity. This generally relatively lower internal funding rate, which is reflected in the economic terms of the notes, along with the fees and charges associated with market-linked notes, resulted in the initial estimated value of the notes on the pricing date being less than their public offering price.

At maturity, we are required to pay the Redemption Amount to holders of the notes, which will be calculated based on the performance of the Basket and the $10 per unit principal amount. In order to meet these payment obligations, at the time we issue the notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with MLPF&S or one of its affiliates.  The terms of these hedging arrangements are determined by seeking bids from market participants, including MLPF&S and its affiliates, and take into account a number of factors, including our creditworthiness, interest rate movements, the volatility of the Basket Components, the tenor of the notes and the tenor of the hedging arrangements. The economic terms of the notes and their initial estimated value depend in part on the terms of these hedging arrangements.

MLPF&S has advised us that the hedging arrangements will include a hedging related charge of approximately $0.075 per unit, reflecting an estimated profit to be credited to MLPF&S from these transactions.  Since hedging entails risk and may be influenced by unpredictable market forces, additional profits and losses from these hedging arrangements may be realized by MLPF&S or any third party hedge providers.

Summary of Canadian Federal Income Tax Consequences

An investor should read carefully the description of principal Canadian federal income tax considerations under “Canadian Taxation” in the accompanying prospectus relevant to a holder (as defined on page 19 of the prospectus) owning debt securities, and the description of principal Canadian federal income tax considerations under “Supplemental Discussion of Canadian Federal Income Tax Consequences” in the applicable product prospectus supplement.

Summary of U.S. Federal Income Tax Consequences

The following is a general description of certain U.S. federal tax considerations relating to the notes. Prospective purchasers of the notes should consult their tax advisors as to the consequences under the tax laws of the country of which they are residents for tax purposes and the tax laws of the U.S. of acquiring, holding and disposing of the notes and receiving payments under the notes. This summary is based upon the law as in effect on the date of this pricing supplement and is subject to any change in law that may take effect after such date. We urge you to read the more detailed discussion in the “Supplemental Discussion of U.S. Federal Income Tax Consequences” section beginning on page PS-30 of product prospectus supplement EQUITY INDICES SUN-1.

No statutory, judicial or administrative authority directly discusses how the notes should be treated for U.S. federal income tax purposes. As a result, the U.S. federal income tax consequences of your investment in the notes are uncertain. Accordingly, we urge you to consult your tax advisor as to the tax consequences of your investment in the notes (and of having agreed to the required tax treatment of your notes described below) and as to the application of state, local or other tax laws to your investment in your notes and the possible effects of changes in federal or other tax laws.

We will not attempt to ascertain whether any entity the stock of which is included in the index would be treated as a “passive foreign investment company” (a “PFIC”) within the meaning of the Internal Revenue Code of 1986, as amended (the “Code”). If any such entity were so treated, certain adverse U.S. federal income tax consequences might apply to U.S. holders upon the taxable disposition (including cash settlement) of the notes. You should refer to information filed with the SEC or an equivalent governmental authority by such entities and consult your tax advisor regarding the possible consequences to you if such entity is or becomes a PFIC.

Pursuant to the terms of the notes, BNS and you agree, in the absence of a statutory, regulatory, administrative or judicial ruling to the contrary, to characterize your notes as a pre-paid derivative contract with respect to the Basket. If your notes are so treated, you should generally recognize long-term capital gain or loss if you hold your notes for more than one year (and otherwise, short-term capital gain or loss) upon the sale, exchange, redemption or maturity of your notes in an amount equal to the difference between the amount you receive at such time and the amount you paid for your notes. The deductibility of capital losses is subject to limitations.

In the opinion of our counsel, Cadwalader, Wickersham & Taft LLP, it would be reasonable to treat your notes in the manner described above. However, because there is no authority that specifically addresses the tax treatment of the notes, it is possible that your notes could alternatively be treated for tax purposes as a single contingent payment debt instrument or pursuant to some other characterization, such that the timing and character of your income from the notes could differ materially from the treatment described above.

Possible Change in Law. In 2007, the Internal Revenue Service (“the IRS”) released a notice that may affect the taxation of holders of the notes. According to Notice 2008-2, the IRS and the U.S. Treasury Department are actively considering whether a holder of an instrument such as the notes should be required to accrue ordinary income on a current basis, and they are seeking taxpayer comments on the subject. It is not possible to determine what guidance they will ultimately issue, if any. It is possible, however, that under such guidance, holders of the notes will ultimately be required to accrue income currently and this could be applied on a retroactive basis. The IRS and the U.S. Treasury Department are also considering other relevant issues, including whether additional gain or loss from such instruments should be treated as ordinary or capital, whether foreign holders of such instruments should be subject to withholding tax on any deemed income accruals, and whether the special “constructive ownership rules” of Section 1260 of the Code should be applied to such instruments.

Medicare Tax on Net Investment Income. U.S. holders that are individuals or estates and certain trusts are subject to an additional 3.8% tax on all or a portion of their “net investment income,” or “undistributed net investment income” in the case of an estate or trust, which may include any income or gain with respect to the notes, to the extent of their net investment income or undistributed net investment income (as the case may be) that, when added to their other modified adjusted gross income, exceeds $200,000 for an unmarried individual, $250,000 for a married taxpayer filing a joint return (or a surviving spouse), $125,000 for a married individual filing a separate return, or the dollar amount at which the highest tax bracket begins for an estate or trust (which, in 2017, is $12,500). The 3.8% Medicare tax is determined in a different manner than the regular income tax. U.S. holders should consult their advisors with respect to the 3.8% Medicare tax.

Specified Foreign Financial Assets. U.S. holders may be subject to reporting obligations with respect to their notes if they do not hold their notes in an account maintained by a financial institution and the aggregate value of their notes and certain other “specified foreign financial assets” (applying certain attribution rules) exceeds $50,000. Significant penalties can apply if a U.S. holder is required to disclose its notes and fails to do so.

Backup Withholding and Information Reporting. The proceeds received from a sale, exchange, redemption or maturity of the notes will be subject to information reporting unless you are an “exempt recipient” and may also be subject to backup withholding at the rate

specified in the Code if you fail to provide certain identifying information (such as an accurate taxpayer number, if you are a U.S. holder) or meet certain other conditions.

Amounts withheld under the backup withholding rules are not additional taxes and may be refunded or credited against your U.S. federal income tax liability, provided the required information is furnished to the IRS.

Non-U.S. Holders. This section applies only if you are a non-U.S. holder. For these purposes, you are a non-U.S. holder if you are the beneficial owner of the notes and are, for U.S. federal income tax purposes:

·	a non-resident alien individual;

·	a foreign corporation; or

·	an estate or trust that, in either case, is not subject to U.S. federal income tax on a net income basis on income or gain from the notes.

If you are a non-U.S. holder, subject to Section 871(m) discussed below, you should generally not be subject to generally applicable information reporting and backup withholding requirements with respect to payments on your notes if you comply with certain certification and identification requirements as to your foreign status including providing us (and/or the applicable withholding agent) a properly executed and fully completed applicable IRS Form W-8. Subject to Section 871(m), discussed below, gain from the sale, exchange or redemption of the notes or settlement at maturity generally will not be subject to U.S. tax unless such gain is effectively connected with a trade or business conducted by you in the U.S. or unless you are a non-resident alien individual and are present in the U.S. for 183 days or more during the taxable year of such sale, exchange or settlement and certain other conditions are satisfied.

Section 871(m).  A 30% withholding tax (which may be reduced by an applicable income tax treaty) is imposed under Section 871(m) of the Code on certain “dividend equivalents” paid or deemed paid to a non-U.S. holder with respect to a “specified equity-linked instrument” that references one or more dividend-paying U.S. equity securities or indices containing U.S. equity securities. The withholding tax can apply even if the instrument does not provide for payments that reference dividends.  Treasury regulations provide that the withholding tax applies to all dividend equivalents paid or deemed paid on specified equity-linked instruments that have a delta of one (“delta one specified equity-linked instruments”) issued after 2016 and to all dividend equivalents paid or deemed paid on all other specified equity-linked instruments issued after 2018.

In light of the nature of the notes and the Basket, our counsel is of the opinion that the notes should not be subject to withholding on dividend equivalents. Our determination is not binding on the IRS, and the IRS may disagree with this determination. Furthermore, the application of Section 871(m) of the Code will depend on our determinations made upon issuance of the notes. If withholding is required, we will not make payments of any additional amounts.

Nevertheless, after issuance, it is possible that your notes could be deemed to be reissued for tax purposes upon the occurrence of certain events affecting the Basket Components or stocks comprising any Basket Component or your notes, and following such occurrence your notes could be treated as delta one specified equity-linked instruments that are subject to withholding on dividend equivalents. It is also possible that withholding tax or other tax under Section 871(m) of the Code could apply to the notes under these rules if a non-U.S. holder enters, or has entered, into certain other transactions in respect of the Basket Components or stocks comprising any Basket Component or the notes. A non-U.S. holder that enters, or has entered, into other transactions in respect of the Basket Components or stocks comprising any Basket Component or the notes should consult its own tax advisor regarding the application of Section 871(m) of the Code to its notes in the context of its other transactions.

Because of the uncertainty regarding the application of the 30% withholding tax on dividend equivalents to the notes, you are urged to consult your tax advisor regarding the potential application of Section 871(m) of the Code and the 30% withholding tax to an investment in the notes.

U.S. Federal Estate Tax Treatment of Non-U.S. Holders. A note may be subject to U.S. federal estate tax if an individual non-U.S. holder holds the note at the time of his or her death. The gross estate of a non-U.S. holder domiciled outside the U.S. includes only property situated in the U.S. Individual non-U.S. holders should consult their tax advisors regarding the U.S. federal estate tax consequences of holding the notes at death.

FATCA. The Foreign Account Tax Compliance Act (“FATCA”) was enacted on March 18, 2010, and imposes a 30% U.S. withholding tax on “withholdable payments” (i.e., certain U.S.-source payments, including interest (and original issue discount), dividends, other fixed or determinable annual or periodical gain, profits, and income, and on the gross proceeds from a disposition of property of a type which can produce U.S.-source interest or dividends) and “passthru payments” (i.e., certain payments attributable to withholdable payments) made to certain foreign financial institutions (and certain of their affiliates) unless the payee foreign financial institution agrees (or is required), among other things, to disclose the identity of any U.S. individual with an account at the institution (or the relevant affiliate) and to annually report certain information about such account. FATCA also requires withholding agents making withholdable payments to certain foreign entities that do not disclose the name, address, and taxpayer identification number of any substantial U.S. owners (or do not certify that they do not have any substantial U.S. owners) to withhold tax at a rate of 30%. Under certain circumstances, a holder may be eligible for refunds or credits of such taxes.

Pursuant to final and temporary Treasury regulations and other IRS guidance, the withholding and reporting requirements under FATCA will generally apply to certain “withholdable payments” made on or after July 1, 2014, certain gross proceeds on a sale or disposition occurring after December 31, 2018, and certain foreign passthru payments made after December 31, 2018 (or, if later, the date that final regulations defining the term “foreign passthru payment” are published). If withholding is required, we (or the applicable paying agent) will not be required to pay additional amounts with respect to the amounts so withheld. Foreign financial institutions and non-

financial foreign entities located in jurisdictions that have an intergovernmental agreement with the U.S. governing FATCA may be subject to different rules.

Investors should consult their own advisors about the application of FATCA, in particular if they may be classified as financial institutions (or if they hold their notes through a non-U.S. entity) under the FATCA rules.

Both U.S. and non-U.S. holders should consult their tax advisors regarding the U.S. federal income tax consequences of an investment in the notes, as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction (including that of the issuers of stocks included in the Basket Components and BNS).

Market-Linked Investments Classification

MLPF&S classifies certain market-linked investments (the “Market-Linked Investments”) into categories, each with different investment characteristics. The following description is meant solely for informational purposes and is not intended to represent any particular Enhanced Return Market-Linked Investment or guarantee any performance.

Enhanced Return Market-Linked Investments are short- to medium-term investments that offer you a way to enhance exposure to a particular market view without taking on a similarly enhanced level of market downside risk. They can be especially effective in a flat to moderately positive market (or, in the case of bearish investments, a flat to moderately negative market). In exchange for the potential to receive better-than market returns on the linked asset, you must generally accept market downside risk and capped upside potential.  As these investments are not market downside protected, and do not assure full repayment of principal at maturity, you need to be prepared for the possibility that you may lose all or part of your investment.
