Subject to Completion PRELIMINARY PRICING SUPPLEMENT Dated January 29, 2019 Filed Pursuant to Rule 424(b)(2) Registration Statement No. 333-225551 (To Prospectus dated October 31, 2018, Index Supplement dated October 31, 2018 and Product Supplement dated October 31, 2018)

UBS AG $• Trigger Autocallable Notes

Linked to the least performing between the shares of the iShares^® MSCI Emerging Markets ETF and the EURO STOXX 50^® Index due on or about March 8, 2023

Investment Description

UBS AG Trigger Autocallable Notes (the “Notes”) are unsubordinated, unsecured debt securities issued by UBS AG (“UBS” or the “issuer”) linked to the least performing between the shares of the iShares^® MSCI Emerging Markets ETF (the “underlying equity” or an “underlying asset”) and the EURO STOXX 50^® Index (the “underlying index” or an “underlying asset”). UBS will automatically call the Notes (an “automatic call”) if the closing level of each underlying asset on any observation date, including the final valuation date, is equal to or greater than its call threshold level, which is equal to a specified level that is less than its initial level, as indicated below. If the Notes are subject to an automatic call, UBS will pay on the applicable call settlement date following such observation date a cash payment per Note equal to the “call price”, which is your principal amount plus a call return based on the call return rate, and no further payments will be owed to you under the Notes. The call return increases the longer the Notes are outstanding. If the Notes are not subject to an automatic call and the closing level of each underlying asset on the final valuation date (the “final level”) is equal to or greater than its downside threshold, UBS will pay you a cash payment per Note equal to the principal amount. If, however, the Notes are not subject to an automatic call and the final level of any underlying asset is less than its downside threshold, UBS will pay you a cash payment per Note that is less than the principal amount, if anything, resulting in a percentage loss on your initial investment equal to the underlying return of the least performing underlying asset and, in extreme situations, you could lose all of your initial investment. The “least performing underlying asset” is the underlying asset with the lowest underlying return as compared to any other underlying asset. Investing in the Notes involves significant risks. You may lose a significant portion or all of your initial investment. You will be exposed to the market risk of each underlying asset on each observation date and on the final valuation date and any decline in the level of one underlying asset may negatively affect your return and will not be offset or mitigated by a lesser decline or any potential increase in the level of any other underlying asset. Higher call return rates are generally associated with a greater risk of loss and a greater risk that the Notes will not be subject to an automatic call. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of UBS. If UBS were to default on its payment obligations you may not receive any amounts owed to you under the Notes and you could lose all of your initial investment.

 

Notice to investors: the Notes are significantly riskier than conventional debt instruments. The issuer is not necessarily obligated to repay the principal amount of the Notes at maturity, and the Notes may have the same downside market risk as the least performing underlying asset. This market risk is in addition to the credit risk inherent in purchasing a debt obligation of UBS. You should not purchase the Notes if you do not understand or are not comfortable with the significant risks involved in investing in the Notes. You should carefully consider the risks described under “Key Risks” beginning on page 4 and under “Risk Factors” beginning on page PS-9 of the accompanying product supplement before purchasing any Notes. Events relating to any of those risks, or other risks and uncertainties, could adversely affect the market value of, and the return on, your Notes. You may lose a significant portion or all of your initial investment in the Notes. The Notes will not be listed or displayed on any securities exchange or any electronic communications network.

Preliminary Terms

Investment Timeline

 

Trade Date	The initial level of each underlying asset is observed and the final terms of the Notes are set.
¯
Observation Dates (Annually)	The Notes will be subject to an automatic call if the closing level of each underlying asset on any observation date, including the final valuation date, is equal to or greater than its call threshold level. If the Notes are subject to an automatic call, UBS will pay on the call settlement date a cash payment per Note equal to the call price for the relevant observation date. Following an automatic call, no further payments will be made on the Notes.
¯
Maturity Date	The final level of each underlying asset is observed on the final valuation date and the underlying return of each underlying asset is calculated. If the Notes are not subject to an automatic call and the final level of each underlying asset is equal to or greater than its downside threshold, UBS will pay you a cash payment that is equal to: Principal Amount of $1,000 If the Notes are not subject to an automatic call and the final level of at least one underlying asset is less than its downside threshold, UBS will pay you a cash payment that is less than the principal amount, if anything, equal to: $1,000 x (1 + Underlying Return of the Least Performing Underlying Asset) In this scenario, you will suffer a percentage loss on your initial investment equal to the underlying return of the least performing underlying asset, regardless of the underlying return of any other underlying asset.

Investing in the Notes involves significant risks. You may lose a significant portion or all of your initial investment. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of UBS. If UBS were to default on its payment obligations, you may not receive any amounts owed to you under the Notes and you could lose all of your initial investment.

If the Notes are not subject to an automatic call, you may lose a significant portion or all of your initial investment. Specifically, if the Notes are not subject to an automatic call and the final level of any underlying asset is less than its downside threshold, you will lose a percentage of your principal amount equal to the underlying return of the least performing underlying asset and, in extreme situations, you could lose all of your initial investment. You will be exposed to the market risk of each underlying asset on each observation date, including the final valuation date, and any decline in the level of one underlying asset may negatively affect your return and will not be offset or mitigated by a lesser decline or any potential increase in the level of any other underlying asset.

Key Risks

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to a hypothetical investment in the least performing underlying asset or its underlying constituents. Some of the key risks that apply to the Notes are summarized below, but we urge you to read the more detailed explanation of risks relating to the Notes in the “Risk Factors” section of the accompanying product supplement. We also urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the Notes.

¨

Risk of loss at maturity — The Notes differ from ordinary debt securities in that UBS will not necessarily repay the principal amount of the Notes at maturity. If the Notes are not subject to an automatic call and the final level of any underlying asset is less than its downside threshold, you will lose a percentage of your principal amount equal to the underlying return of the least performing underlying asset and, in extreme situations, you could lose all of your initial investment.

¨

The contingent repayment of principal applies only at maturity — You should be willing to hold your Notes to maturity. If you are able to sell your Notes prior to an automatic call or maturity in the secondary market, you may have to sell them at a loss relative to your initial investment even if the level of each underlying asset at that time is equal to or greater than its downside threshold and call threshold level. All payments on the Notes are subject to the creditworthiness of UBS.

¨

No interest payments — UBS will not pay any interest with respect to the Notes.

¨

Your potential return on the Notes is limited to any call return and you will not participate in any appreciation of any underlying asset or underlying constituent — The return potential of the Notes is limited to the pre-specified call return resulting from an automatic call regardless of any appreciation of any underlying asset. Investors will not participate in any appreciation in the closing level of any underlying asset from its initial level. The Notes will only be subject to an automatic call if the closing level or the final level, as applicable, of each underlying asset is equal to or greater than its call threshold level. In addition, because the call return increases the longer the Notes have been outstanding, the call price payable with respect to earlier observation dates is less than the call price payable with respect to later observation dates. The earlier a Note is subject to an automatic call, the lower your return will be. Because the Notes may be subject to an automatic call as early as the first potential call settlement date, the total return on the Notes could be less than if the Notes remained outstanding until maturity. Furthermore, if the Notes are not subject to an automatic call and the final level of at least one underlying asset is less than its downside threshold, you will be subject to the decline in the level of the least performing underlying asset even though you cannot participate in any appreciation in the level of any underlying asset. As a result, the return on an investment in the Notes could be less than the return on a hypothetical direct investment in any or all of the underlying assets or underlying constituents. In addition, as an owner of the Notes, you will not have voting rights or any other rights of a holder of the underlying equity or any underlying constituent.

¨

A higher call return rate or lower downside thresholds or call threshold levels may reflect greater expected volatility of each underlying asset, and greater expected volatility generally indicates an increased risk of loss at maturity — The economic terms for the Notes, including the call return rate, call threshold levels and downside thresholds, are based, in part, on the expected volatility of each underlying asset at the time the terms of the Notes are set. “Volatility” refers to the frequency and magnitude of changes in the level of each underlying asset. The greater the expected volatility of each underlying asset as of the trade date, the greater the expectation is as of that date that the closing level or the final level, as applicable, of each underlying asset could be less than its call threshold level on any observation date (including the final valuation date) and that the final level of each underlying asset could be less than its downside threshold on the final valuation date and, as a consequence, indicates an increased risk of the Notes not being subject to an automatic call and an increased risk of loss, respectively. All things being equal, this greater expected volatility will generally be reflected in a higher call return rate than the yield payable on our conventional debt securities with a similar maturity or on otherwise comparable securities, and/or lower downside thresholds and/or call threshold levels than those terms on otherwise comparable securities. Therefore, a relatively higher call return rate may indicate an increased risk of loss. Further, relatively lower downside thresholds and/or call threshold levels may not necessarily indicate that the Notes have a greater likelihood of a return of principal at maturity and/or paying the call return. You should be willing to accept the downside market risk of the least performing underlying asset and the potential to lose a significant portion or all of your initial investment.

¨

Reinvestment risk — The Notes will be subject to an automatic call if the closing level of each underlying asset is equal to or greater than its call threshold level on any observation date set forth herein. Because the Notes could be subject to an automatic call as early as the first potential call settlement date, the term of your investment may be limited. In the event that the Notes are subject to an automatic call, there is no guarantee that you would be able to reinvest the proceeds at a comparable return and/or with a comparable call return rate for a similar level of risk. In addition, to the extent you are able to reinvest such proceeds in an investment comparable to the Notes, you may incur transaction costs such as dealer discounts and/or fees and hedging costs built into the price of the new securities. Generally, however, the longer the Notes remain outstanding, the less likely the Notes will be subject to an automatic call due to the decline in the level of an underlying asset and the shorter time remaining for the level of any such underlying asset to recover. Such periods generally coincide with a period of greater risk of principal loss on your Notes.

¨

You are exposed to the market risk of each underlying asset — Your return on the Notes is not linked to a basket consisting of the underlying assets. Rather, it will be contingent upon the performance of each underlying asset. Unlike an instrument with a return linked to a basket of indices, common stocks, exchange-traded funds or other underlying securities, in which risk is mitigated and diversified among all of the components of the basket, you will be exposed equally to the risks related to each underlying asset. Poor performance by any underlying asset over the term of the Notes will negatively affect your return and will not be offset or mitigated by a positive performance by any other underlying asset. For instance, you may receive a negative return equal to the underlying return of the least performing underlying asset if the final level of any underlying asset is less than its downside threshold, even if the underlying return of any other underlying asset is positive or has not declined as much. Accordingly, your investment is subject to the market risk of each underlying asset.

¨

Because the Notes are linked to the least performing underlying asset, you are exposed to a greater risk of not receiving the call return and losing a significant portion or all of your initial investment at maturity than if the Notes were linked to a single underlying asset or fewer underlying assets — The risk that you will not receive the call return and will lose a significant portion or all of your initial investment in the Notes is greater if you invest in the Notes than the risk of investing in substantially similar securities that are linked to the performance of only one underlying asset or fewer underlying assets, as applicable. With more underlying assets, it is more likely that the closing level or final level of any underlying asset will be less than its call threshold level or downside threshold on any observation date or the final valuation date, respectively, than if the Notes were linked to a single underlying asset or fewer underlying assets, as applicable.

In addition, the lower the correlation is between the performance of a pair of underlying assets, the more likely it is that one of the underlying assets will decline in value to a closing level or final level, as applicable, that is less than its call threshold level or downside threshold on any observation date or on the final valuation date. Although the correlation of the underlying assets’ performance may change over the term of the Notes, the economic terms of the Notes, including the call return rate, downside thresholds and call threshold levels are determined, in part, based on the correlation of the underlying assets’ performance calculated using our internal models at the time when the terms of the Notes are finalized. All things being equal, a higher call return rate and lower downside thresholds and call threshold levels are generally associated with lower correlation of the underlying assets. Therefore, if the performance of a pair of underlying assets is not correlated to each other or is negatively correlated, the risk that you will not receive the call return or that the final level of any underlying asset is less than its downside threshold will occur is even greater despite a lower call threshold level and/or downside threshold. Therefore, it is more likely that you will not receive the call return and that you will lose a significant portion or all of your initial investment at maturity.

¨

Credit risk of UBS — The Notes are unsubordinated, unsecured debt obligations of UBS and are not, either directly or indirectly, an obligation of any third party. Any payment to be made on the Notes, including any repayment of principal, depends on the ability of UBS to satisfy its obligations as they come due. As a result, UBS’ actual and perceived creditworthiness may affect the market value of the Notes. If UBS were to default on its obligations, you may not receive any amounts owed to you under the terms of the Notes and you could lose all of your initial investment.

¨

Market risk — The return on the Notes, which may be negative, is directly linked to the performance of the underlying assets and indirectly linked to the performance of the underlying constituents and, in the case of the underlying equity, the other assets comprising the underlying equity (collectively, the “underlying constituents”). The levels of the underlying assets can rise or fall sharply due to factors specific to each underlying asset, or its underlying constituents and their respective issuers, as applicable, (each, an “underlying constituent issuer”), such as stock or commodity price volatility, earnings and financial conditions, corporate, industry and regulatory developments, management changes and decisions and other events, as well as general market factors, such as general stock or commodity market levels and volatility, interest rates and economic and political conditions.

¨	Fair value considerations.

○

The issue price you pay for the Notes will exceed their estimated initial value — The issue price you pay for the Notes will exceed their estimated initial value as of the trade date due to the inclusion in the issue price of the applicable underwriting commissions and fees, hedging costs, issuance costs and projected profits. As of the close of the relevant markets on the trade date, we will determine the estimated initial value of the Notes by reference to our internal pricing models and the estimated initial value of the Notes will be set forth in the applicable pricing supplement. The pricing models used to determine the estimated initial value of the Notes incorporate certain variables, including the levels of the underlying assets and underlying constituents, the volatility of the underlying assets, any dividends paid on the underlying equity or the underlying constituents, as applicable, the correlation among the underlying assets, prevailing interest rates, the term of the Notes and our internal funding rate. Our internal funding rate is typically lower than the rate we would pay to issue conventional fixed or floating rate debt securities of a similar term. The applicable underwriting commissions and fees, hedging costs, issuance costs, projected profits and the difference in rates will reduce the economic value of the Notes to you. Due to these factors, the estimated initial value of the Notes as of the trade date will be less than the issue price you pay for the Notes.

○

The estimated initial value is a theoretical price; the actual price that you may be able to sell your Notes in any secondary market (if any) at any time after the trade date may differ from the estimated initial value — The value of your Notes at any time will vary based on many factors, including the factors described above and in “— Market risk” above and is impossible to predict. Furthermore, the pricing models that we use are proprietary and rely in part on certain assumptions about future events, which may prove to be incorrect. As a result, after the trade date, if you attempt to sell the Notes in the secondary market, the actual value you would receive may differ, perhaps materially, from the estimated initial value of the Notes determined by reference to our internal pricing models. The estimated initial value of the Notes does not represent a minimum or maximum price at which we or any of our affiliates would be willing to purchase your Notes in any secondary market at any time.

○

Our actual profits may be greater or less than the differential between the estimated initial value and the issue price of the Notes as of the trade date — We may determine the economic terms of the Notes, as well as hedge our obligations, at least in part, prior to the trade date. In addition, there may be ongoing costs to us to maintain and/or adjust any hedges and such hedges are often imperfect. Therefore, our actual profits (or potentially, losses) in issuing the Notes cannot be determined as of the trade date and any such differential between the estimated initial value and the issue price of the Notes as of the trade date does not reflect our actual profits. Ultimately, our actual profits will be known only at the maturity of the Notes.

¨

Limited or no secondary market and secondary market price considerations.

○

There may be little or no secondary market for the Notes — The Notes will not be listed or displayed on any securities exchange or any electronic communications network. UBS Securities LLC and its affiliates intend, but are not required, to make a market for the Notes and may stop making a market at any time. If you are able to sell your Notes prior to maturity, you may have to sell them at a substantial loss. Furthermore, there can be no assurance that a secondary market for the Notes will develop. The estimated initial value of the Notes does not represent a minimum or maximum price at which we or any of our affiliates would be willing to purchase your Notes in any secondary market at any time.

○

The price at which UBS Securities LLC and its affiliates may offer to buy the Notes in the secondary market (if any) may be greater than UBS’ valuation of the Notes at that time, greater than any other secondary market prices provided by unaffiliated dealers (if any) and, depending on your broker, greater than the valuation provided on your customer account statements — For a limited period of time following the issuance of the Notes, UBS Securities LLC or its affiliates may offer to buy or sell such Notes at a price that exceeds (i) our valuation of the Notes at that time based on our internal pricing models, (ii) any secondary market prices provided by unaffiliated dealers (if any) and (iii) depending on your broker, the valuation provided on customer account statements. The price that UBS Securities LLC may initially offer to buy such Notes following issuance will exceed the valuations indicated by our internal pricing models due to the inclusion for a limited period of time of the aggregate value of the applicable underwriting commissions and fees, hedging costs, issuance costs and theoretical projected trading profit. The portion of such amounts included in our price will decline to zero on a straight line basis over a period ending no later than the date specified under “Supplemental Plan of Distribution (Conflicts of Interest); Secondary Markets (if any).” Thereafter, if UBS Securities LLC or an affiliate makes secondary markets in the Notes, it will do so at prices that reflect our estimated value determined by reference to our internal pricing models at that time. The temporary positive differential relative to our internal pricing models arises from requests from and arrangements made by UBS

Securities LLC with the selling agents of structured debt securities such as the Notes. As described above, UBS Securities LLC and its affiliates intend, but are not required, to make a market for the Notes and may stop making a market at any time. The price at which UBS Securities LLC or an affiliate may make secondary markets at any time (if at all) will also reflect its then current bid-ask spread for similar sized trades of structured debt securities. UBS Securities LLC reflects this temporary positive differential on its customer statements. Investors should inquire as to the valuation provided on customer account statements provided by unaffiliated dealers.

○

Economic and market factors affecting the terms and market price of Notes prior to maturity — Because structured notes, including the Notes, can be thought of as having a debt component and a derivative component, factors that influence the values of debt instruments and options and other derivatives will also affect the terms and features of the Notes at issuance and the market price of the Notes prior to maturity. These factors include the levels of the underlying assets and underlying constituents; the volatility of the underlying assets; any dividends paid on the underlying equity or the underlying constituents; the correlation among the underlying assets; the time remaining to the maturity of the Notes; interest rates in the markets; geopolitical conditions and economic, financial, political, force majeure and regulatory or judicial events; whether each underlying asset is currently or has been less than its call threshold level; the availability of comparable instruments; the creditworthiness of UBS; the then current bid-ask spread for the Notes and the factors discussed under “— Potential conflict of interest” below. These and other factors are unpredictable and interrelated and may offset or magnify each other.

○

Impact of fees and the use of internal funding rates rather than secondary market credit spreads on secondary market prices — All other things being equal, the use of the internal funding rates described above under “—Fair value considerations” as well as the inclusion in the issue price of the applicable underwriting commissions and fees, hedging costs, issuance costs and any projected profits are, subject to the temporary mitigating effect of UBS Securities LLC’s and its affiliates’ market making premium, expected to reduce the price at which you may be able to sell the Notes in any secondary market.

¨

The value of the underlying equity may not completely track the value of the underlying constituents in which such exchange traded fund (the “ETF”) invests — Although the trading characteristics and valuations of the underlying equity will usually mirror the characteristics and valuations of its underlying constituents, its value may not completely track the value of its underlying constituents. The value of the underlying equity will reflect transaction costs and fees that its underlying constituents do not have. In addition, although the underlying equity may be currently listed for trading on an exchange, there is no assurance that an active trading market will continue for the underlying equity or that there will be liquidity in the trading market.

¨

The Notes are subject to non-U.S. securities market risk — The Notes are subject to risks associated with non-U.S. companies and non-U.S. securities markets because the underlying assets are comprised of stocks issued by non-U.S. companies that are traded on various non-U.S. exchanges. An investment in securities linked directly or indirectly to the value of securities issued by non-U.S. companies involves particular risks. Generally, non-U.S. securities markets may be more volatile than U.S. securities markets, and market developments may affect non-U.S. markets differently from U.S. securities markets. Direct or indirect government intervention to stabilize these non-U.S. markets, as well as cross shareholdings in non-U.S. companies, may affect trading prices and volumes in those markets. There is generally less publicly available information about non-U.S. companies than about those U.S. companies that are subject to the reporting requirements of the SEC, and non-U.S. companies are subject to accounting, auditing and financial reporting standards and requirements that differ from those applicable to U.S. reporting companies. Securities prices in non-U.S. countries are subject to political, economic, financial and social factors that may be unique to the particular country. These factors, which could negatively affect the non-U.S. securities markets, include the possibility of recent or future changes in the non-U.S. government’s economic and fiscal policies, the possible imposition of, or changes in, currency exchange laws or other non-U.S. laws or restrictions applicable to non-U.S. companies or investments in non-U.S. equity securities and the possibility of fluctuations in the rate of exchange between currencies. The United Kingdom has voted to leave the European Union (popularly known as “Brexit”). The effect of Brexit is uncertain, and Brexit has and may continue to contribute to volatility in the prices of securities of companies located in Europe and currency exchange rates, including the valuation of the euro and British pound in particular. Moreover, certain aspects of a particular non-U.S. economy may differ favorably or unfavorably from the U.S. economy in important respects, such as growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency.

¨

The Notes are subject to emerging markets risk related to the underlying equity — The Notes are subject to risks associated with emerging market companies and emerging market securities because the underlying equity seeks to track the performance of the MSCI Emerging Markets Index (its “target index”) and, therefore, is comprised of stocks of emerging market companies that are traded on various emerging market exchanges. Investments in securities linked directly or indirectly to emerging market equity securities involve many risks, including, but not limited to: economic, social, political, financial and military conditions in the emerging market; regulation by national, provincial, and local governments; less liquidity and smaller market capitalizations than exist in the case of many large U.S. companies; different accounting and disclosure standards; and political uncertainties. Securities of emerging market companies may be more volatile and may be affected by market developments differently than U.S. companies. Government interventions to stabilize securities markets and cross-shareholdings may affect prices and volume of trading of the securities of emerging market companies. Economic, social, political, financial and military factors could, in turn, negatively affect such companies’ value. These factors could include changes in the emerging market government’s economic and fiscal policies, possible imposition of, or changes in, currency exchange laws or other laws or restrictions applicable to the emerging market companies or investments in their securities, and the possibility of fluctuations in the rate of exchange between currencies. Moreover, emerging market economies may differ favorably or unfavorably from the U.S. economy in a variety of ways, including growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency. You should carefully consider the risks related to emerging markets, to which the Notes are susceptible.

¨

The Notes are subject to currency exchange risk— The underlying constituents of the EURO STOXX 50® Index are traded and quoted in non-U.S. currencies on non-U.S. markets. The prices of its underlying constituents will not be adjusted for exchange rate fluctuations between the U.S. dollar and the currencies in which the EURO STOXX 50® Index underlying constituents are quoted and traded. Therefore, if the applicable currencies appreciate or depreciate relative to the U.S. dollar over the term of the Notes, you will not receive any additional payment or incur any reduction in your return, if any, at maturity.

Further, the underlying constituents of the underlying equity are traded and quoted in non-U.S. currencies on non-U.S. markets. The prices of its underlying constituents are converted into U.S. dollars for purposes of calculating the level of the underlying equity. As a result, holders of the Notes will be exposed to currency exchange rate risk with respect to each of the currencies represented in the underlying equity. The values of the currencies of its underlying constituents may be subject to a high degree of fluctuation due to changes in interest rates, the effects of monetary policies issued by the United States, non-U.S. governments, central banks or supranational entities, the imposition of currency controls or other national or global political or economic developments. The level of the underlying equity will depend on the extent to which the relevant non-U.S. currencies strengthen or weaken against the U.S. dollar and the relative weight of each of its non-U.S. underlying constituents. If, taking into account such weighting, the U.S. dollar

strengthens against the relevant non-U.S. currencies, the level of the applicable underlying constituent, and therefore the level of the underlying equity will be adversely affected.

It has been reported that the U.K. Financial Conduct Authority and regulators from other countries are in the process of investigating the potential manipulation of published currency exchange rates. If such manipulation has occurred or is continuing, certain published exchange rates may have been, or may be in the future, artificially lower (or higher) than they would otherwise have been. Any such manipulation could have an adverse impact on any payments on, and the value of, your Notes and the trading market for your Notes. In addition, we cannot predict whether any changes or reforms affecting the determination or publication of exchange rates or the supervision of currency trading will be implemented in connection with these investigations. Any such changes or reforms could also adversely impact your Notes.

¨

Fluctuation of NAV — The net asset value (the “NAV”) of the underlying equity may fluctuate with changes in the market value of the underlying constituents. The market values of the underlying equity may fluctuate in accordance with changes in NAV and supply and demand on the applicable stock exchanges. Furthermore, the underlying constituents may be unavailable in the secondary market during periods of market volatility, which may make it difficult for market participants to accurately calculate the intraday NAV per share of the underlying equity and may adversely affect the liquidity and prices of the underlying equity, perhaps significantly. For any of these reasons, the market value of the underlying equity may differ from its NAV per share and may trade at, above or below its NAV per share.

¨

Failure of the underlying equity to track the level of its target index — While the underlying equity is designed and intended to track the target index, various factors, including fees and other transaction costs, will prevent the underlying equity from correlating exactly with changes in the level of the target index. Accordingly, the performance of the underlying equity will not be equal to the performance of its target index during the term of the Notes.

¨

The underlying equity utilizes a passive indexing investment approach — The underlying equity is not managed according to traditional methods of “active” investment management, which involve the buying and selling of securities based on economic, financial and market analysis and investment judgment. Instead, the underlying equity, utilizing a “passive” or indexing investment approach, attempts to approximate the investment performance of the target index by investing in underlying constituents that generally replicate the target index. Therefore, unless a specific stock is removed from the target index, the underlying equity generally would not sell a stock because the stock’s issuer was in financial trouble. In addition, the underlying equity is subject to the risk that the investment strategy of the underlying equity’s investment adviser may not produce the intended results.

¨

There can be no assurance that the investment view implicit in the Notes will be successful — It is impossible to predict whether and the extent to which the levels of the underlying assets will rise or fall and there can be no assurance that the closing level or the final level, as applicable, of each underlying asset will be equal to or greater than its call threshold level on any observation date (including the final valuation date), or, if the Notes are not subject to an automatic call, that the final level of each underlying asset will be equal to or greater than its downside threshold. The levels of the underlying assets will be influenced by complex and interrelated political, economic, financial and other factors that affect the underlying constituent issuers. You should be willing to accept the risks associated with the relevant markets tracked by each such underlying asset in general and its underlying constituents in particular, and the risk of losing a significant portion or all of your initial investment.

¨

The underlying index reflects price return, not total return and you will not have the rights of a holder of shares of the underlying equity — The return on your Notes is based, in part, on the performance of the underlying index, which reflect the changes in the market prices of its underlying constituents. It is not, however, linked to a “total return” index or strategy, which, in addition to reflecting those price returns, would also reflect dividends paid on its underlying constituents. The return on your Notes will not include such a total return feature or dividend component. The return on the Notes is also based, in part, on the performance of the underlying equity, but holding the Notes is not the same as holding shares of the underlying equity. You will not have the right to receive any dividends or other distributions paid on the underlying equity or have the right to vote or any other rights of a shareholder of the underlying equity.

¨

Changes affecting the underlying index or the target index could have an adverse effect on the Notes — The policies of the index sponsor and the sponsor of the target index, each as specified under “Information About the Underlying Assets”, concerning additions, deletions and substitutions of the underlying constituents and the manner in which the index sponsor of either index takes account of certain changes affecting those underlying constituents may adversely affect the levels of the underlying index or target index. The policies of the index sponsor with respect to the calculation of the underlying index could also adversely affect the level of the underlying index. The index sponsor may discontinue or suspend calculation or dissemination of the underlying index. Any such actions could have an adverse effect on the value of, or any amounts payable on, the Notes.

¨

The calculation agent can make antidilution and reorganization adjustments to the underlying equity that affect the payment to you at maturity — For antidilution and reorganization events affecting the underlying equity, the calculation agent may make adjustments to its initial level, downside threshold and/or the final level, as applicable, and any other term of the Notes. However, the calculation agent will not make an adjustment in response to every corporate event that could affect the underlying equity. If an event occurs that does not require the calculation agent to make an adjustment, the value of, and any amounts payable on, the Notes may be materially and adversely affected. In addition, all determinations and calculations concerning any such adjustments will be made by the calculation agent. You should be aware that the calculation agent may make any such adjustment, determination or calculation in a manner that differs from that discussed in the accompanying product supplement or herein as necessary to achieve an equitable result. Following certain reorganization events relating to the issuer of the underlying equity (the “underlying equity issuer”) where such issuer is not the surviving entity, the amount of cash you receive at maturity may be based on the equity security of a successor to the respective underlying equity issuer in combination with any cash or any other assets distributed to holders of the underlying equity in such reorganization event. If the underlying equity issuer becomes subject to (i) a reorganization event whereby the underlying asset is exchanged solely for cash, (ii) a merger or consolidation with UBS or any of its affiliates, or (iii) the underlying asset is delisted or otherwise suspended from trading, the amount you receive at maturity may be based on a substitute security. Following a delisting or suspension from trading or discontinuance of the ETF, the amount you receive at maturity may be based on a share of another ETF or a basket of securities, futures contracts, commodities or other assets, as described further under “General Terms of the Securities — Delisting, Discontinuance or Modification of an ETF” in the accompanying product supplement. The occurrence of any antidilution or reorganization event and the consequent adjustments may materially and adversely affect the value of, and any amounts payable on, the Notes, if any. For more information, see the sections “General Terms of the Securities — Antidilution Adjustments for Securities Linked to an Underlying Equity or Equity Basket Asset” and “—Reorganization Events for Securities Linked to an Underlying Equity or Equity Basket Asset” in the accompanying product supplement.

¨

UBS cannot control actions by the index sponsor and the index sponsor has no obligation to consider your interests — UBS and its affiliates are not affiliated with the index sponsor and have no ability to control or predict its actions, including any errors in or discontinuation of public disclosure

regarding methods or policies relating to the calculation of the underlying index. The index sponsor is not involved in the Notes offering in any way and has no obligation to consider your interest as an owner of the Notes in taking any actions that might affect the value of, and any amounts payable on, your Notes.

¨

There is no affiliation between the underlying equity issuer or any underlying constituent issuer and UBS, and UBS is not responsible for any disclosure by such issuers — We and our affiliates may currently, or from time to time in the future engage in business with the underlying equity issuer or any underlying constituent issuer. However, we are not affiliated with the underlying equity issuer or any underlying constituent issuer and are not responsible for such issuers’ public disclosure of information, whether contained in SEC filings or otherwise. You, as an investor in the Notes, should conduct your own investigation into the underlying equity, the underlying equity issuer and each underlying constituent. Neither the underlying equity issuer nor any underlying constituent issuer is involved in the Notes offered hereby in any way and has no obligation of any sort with respect to your Notes. The underlying equity issuer and any underlying constituent issuers have no obligation to take your interests into consideration for any reason, including when taking any corporate actions that might affect the value of, and any amounts payable on, your Notes.

¨

Potential UBS impact on an underlying asset or any underlying constituent — Trading or transactions by UBS or its affiliates in an underlying asset or underlying constituent, listed and/or over-the-counter options, futures, exchange-traded funds or other instruments with returns linked to the performance of that underlying asset or any underlying constituent, as applicable, may adversely affect the market price(s) or level(s) of the applicable underlying asset on any observation date, including the final valuation date and, therefore, the market value of the Notes, any payout pursuant to an automatic call or at maturity.

¨

Potential conflict of interest — UBS and its affiliates may engage in business with the issuer of the underlying equity or any underlying constituent issuer, which may present a conflict between the obligations of UBS and you, as a holder of the Notes. There are also potential conflicts of interest between you and the calculation agent, which will be an affiliate of UBS and which will make potentially subjective judgments. The calculation agent will determine whether the Notes are subject to an automatic call and the payment at maturity of the Notes, if any, based on observed levels of the underlying assets. The calculation agent can postpone the determination of the terms of the Notes on the trade date, or the closing level of any underlying asset on any observation date (including the final valuation date). As UBS determines the economic terms of the Notes, including the call return rate, call threshold levels and downside thresholds, and such terms include the applicable underwriting commissions and fees, hedging costs, issuance costs and projected profits, the Notes represent a package of economic terms. There are other potential conflicts of interest insofar as an investor could potentially get better economic terms if that investor entered into exchange-traded and/or OTC derivatives or other instruments with third parties, assuming that such instruments were available and the investor had the ability to assemble and enter into such instruments.

Additionally, UBS and its affiliates act in various capacities with respect to the Notes, including as a principal, agent or dealer in connection with the sale of the Notes. Such affiliates, and any other third-party dealers, will derive compensation from the distribution of the Notes and such compensation may serve as an incentive to sell these Notes instead of other investments. Furthermore, given that UBS Securities LLC and its affiliates temporarily maintain a market making premium, it may have the effect of discouraging UBS Securities LLC and its affiliates from recommending sale of your Notes in the secondary market.

¨

Potentially inconsistent research, opinions or recommendations by UBS — UBS and its affiliates publish research from time to time on financial markets and other matters that may influence the value of the Notes, or express opinions or provide recommendations that are inconsistent with purchasing or holding the Notes. Any research, opinions or recommendations expressed by UBS or its affiliates may not be consistent with each other and may be modified from time to time without notice. Investors should make their own independent investigation of the merits of investing in the Notes and the underlying assets to which the Notes are linked.

¨

The Notes are not bank deposits — An investment in the Notes carries risks which are very different from the risk profile of a bank deposit placed with UBS or its affiliates. The Notes have different yield and/or return, liquidity and risk profiles and would not benefit from any protection provided to deposits.

¨

If UBS experiences financial difficulties, FINMA has the power to open restructuring or liquidation proceedings in respect of, and/or impose protective measures in relation to, UBS, which proceedings or measures may have a material adverse effect on the terms and market value of the Notes and/or the ability of UBS to make payments thereunder — The Swiss Financial Market Supervisory Authority ("FINMA") has broad statutory powers to take measures and actions in relation to UBS if (i) it concludes that there is justified concern that UBS is over-indebted or has serious liquidity problems or (ii) UBS fails to fulfill the applicable capital adequacy requirements (whether on a standalone or consolidated basis) after expiry of a deadline set by FINMA. If one of these pre-requisites is met, FINMA is authorized to open restructuring proceedings or liquidation (bankruptcy) proceedings in respect of, and/or impose protective measures in relation to, UBS. The Swiss Banking Act grants significant discretion to FINMA in connection with the aforementioned proceedings and measures. In particular, a broad variety of protective measures may be imposed by FINMA, including a bank moratorium or a maturity postponement, which measures may be ordered by FINMA either on a stand-alone basis or in connection with restructuring or liquidation proceedings. The resolution regime of the Swiss Banking Act is further detailed in the FINMA Banking Insolvency Ordinance ("BIO-FINMA"). In a restructuring proceeding, FINMA, as resolution authority, is competent to approve the resolution plan. The resolution plan may, among other things, provide for (a) the transfer of all or a portion of UBS's assets, debts, other liabilities and contracts (which may or may not include the contractual relationship between UBS and the holders of Notes) to another entity, (b) a stay (for a maximum of two business days) on the termination of contracts to which UBS is a party, and/or the exercise of (w) rights to terminate, (x) netting rights, (y) rights to enforce or dispose of collateral or (z) rights to transfer claims, liabilities or collateral under contracts to which UBS is a party, (c) the conversion of UBS's debt and/or other obligations, including its obligations under the Notes, into equity (a "debt-to-equity" swap), and/or (d) the partial or full write-off of obligations owed by UBS (a "write-off"), including its obligations under the Notes. The BIO-FINMA provides that a debt-to-equity swap and/or a write-off of debt and other obligations (including the Notes) may only take place after (i) all debt instruments issued by UBS qualifying as additional tier 1 capital or tier 2 capital have been converted into equity or written-off, as applicable, and (ii) the existing equity of UBS has been fully cancelled. While the BIO-FINMA does not expressly address the order in which a write-off of debt instruments other than debt instruments qualifying as additional tier 1 capital or tier 2 capital should occur, it states that debt-to-equity swaps should occur in the following order: first, all subordinated claims not qualifying as regulatory capital; second, all other claims not excluded by law from a debt-to-equity swap (other than deposits); and third, deposits (in excess of the amount privileged by law). However, given the broad discretion granted to FINMA as the resolution authority, any restructuring plan in respect of UBS could provide that the claims under or in connection with the Notes will be partially or fully converted into equity or written-off, while preserving other obligations of UBS that rank pari passu with, or even junior to, UBS's obligations under the Notes. Consequently, holders of Notes may lose all of some of their investment in the Notes. In the case of restructuring proceedings with respect to a systemically important Swiss bank (such as UBS), the creditors whose claims are affected by the restructuring plan will not have a right to vote on, reject, or seek the suspension of the restructuring plan. In addition, if a restructuring plan has been approved by FINMA, the rights of a creditor to seek judicial review of the restructuring plan (e.g., on the grounds that the plan would unduly prejudice the rights of holders of Notes or otherwise be in violation of the Swiss Banking Act) are very limited. In particular, a

court may not suspend the implementation of the restructuring plan. Furthermore, even if a creditor successfully challenges the restructuring plan, the court can only require the relevant creditor to be compensated ex post and there is currently no guidance as to on what basis such compensation would be calculated or how it would be funded.

¨

Uncertain tax treatment — Significant aspects of the tax treatment of the Notes are uncertain. You should consult your tax advisor about your tax situation. See “What are the Tax Consequences of the Securities” herein and “Material U.S. Federal Income Tax Consequences”, including the section “—Securities Treated as Prepaid Derivatives or Prepaid Forwards”, in the accompanying product supplement.

Hypothetical Examples of How the Notes Might Perform

The below examples are based on hypothetical terms. The actual terms will be set on the trade date and will be indicated on the cover of the applicable pricing supplement.

The examples below illustrate the payment upon a call or at maturity for a $1,000 Note on a hypothetical offering of the Notes, with the following assumptions (amounts may have been rounded for ease of reference):

Principal Amount:	$1,000
Term:	Approximately 4 years
Call return rate:	10.70% per annum
Observation Dates:	Annually
Initial Level:
Underlying Asset A:	$40.00
Underlying Asset B:	3,500
Call Threshold Level:
Underlying Asset A:	$36.00 (which is 90.00% of the Initial Level)
Underlying Asset B:	3,150 (which is 90.00% of the Initial Level)
Downside Threshold:
Underlying Asset A:	$28.00 (which is 70.00% of the Initial Level)
Underlying Asset B:	2,450 (which is 70.00% of the Initial Level)

Example 1 — The Closing Level of each Underlying Asset is equal to or greater than its Call Threshold Level on the Observation Date corresponding to the first Potential Call Settlement Date.

Date	Closing Level	Payment (per Note)
First Observation Date	Underlying Asset A: $38.00 (equal to or greater than Call Threshold Level) Underlying Asset B: 3,530 (equal to or greater than Call Threshold Level)	$1,107.00 (Call Price)
	Total Payment	$1,107.00 (10.70% total return)

Because the Notes are subject to an automatic call on the first potential call settlement date (which is approximately one year after the trade date), UBS will pay on the call settlement date a total of $1,107.00 per Note (reflecting your principal amount plus the applicable call return), a 10.70% total return on the Notes. You will not receive any further payments on the Notes.

Example 2 — The Final Level of each Underlying Asset is equal to or greater than its Call Threshold Level on the Final Valuation Date.

Date	Closing Level	Payment (per Note)
First Observation Date	Underlying Asset A: $35.00 (less than Call Threshold Level) Underlying Asset B: 3,000 (less than Call Threshold Level)	$0
Second Observation Date	Underlying Asset A: $38.00 (equal to or greater than Call Threshold Level) Underlying Asset B: 2,850 (less than Call Threshold Level)	$0
Third Observation Date	Underlying Asset A: $34.00 (less than Call Threshold Level) Underlying Asset B: 2,800 (less than Call Threshold Level)	$0
Final Valuation Date	Underlying Asset A: $39.00 (equal to or greater than Call Threshold Level) Underlying Asset B: 3,250 (equal to or greater than Call Threshold Level)	$1,428.00 (Call Price)
	Total Payment	$1,428.00 (42.80% total return)

Because the Notes are subject to an automatic call on the final valuation date (which is approximately four years after the trade date), UBS will pay on the call settlement date a total of $1,428.00 per Note (reflecting your principal amount plus the applicable call return), a 42.80% total return on the Notes.

Example 3 — The Notes are NOT subject to an Automatic Call and the Final Level of each Underlying Asset is equal to or greater than its Downside Threshold.

Date	Closing Level	Payment (per Note)
First Observation Date	Underlying Asset A: $30.00 (less than Call Threshold Level) Underlying Asset B: 2,720 (less than Call Threshold Level)	$0
Second Observation Date	Underlying Asset A: $32.50 (less than Call Threshold Level) Underlying Asset B: 3,200 (equal to or greater than Call Threshold Level)	$0
Third Observation Date	Underlying Asset A: $35.00 (less than Call Threshold Level) Underlying Asset B: 2,600 (less than Call Threshold Level)	$0
Final Valuation Date	Underlying Asset A: $39.00 (equal to or greater than Call Threshold Level) Underlying Asset B: 2,700 (less than Call Threshold Level and equal to or greater than Downside Threshold)	$1,000.00 (Payment at Maturity)
	Total Payment	$1,000.00 (0.00% return)

Because the Notes are not subject to an automatic call and the final level of each underlying asset is equal to or greater than its downside threshold, UBS will pay on the call settlement date a total of $1,000.00 per Note (reflecting your principal amount), a 0.00% total return on the Notes.

Example 4 — The Notes are NOT subject to an Automatic Call and the Final Level of an Underlying Asset is less than its Downside Threshold.

Date	Closing Level	Payment (per Note)
First Observation Date	Underlying Asset A: $33.00 (less than Call Threshold Level) Underlying Asset B: 2,800 (less than Call Threshold Level)	$0
Second Observation Date	Underlying Asset A: $28.00 (less than Call Threshold Level) Underlying Asset B: 3,600 (equal to or greater than Call Threshold Level)	$0
Third Observation Date	Underlying Asset A: $30.00 (less than Call Threshold Level) Underlying Asset B: 3,000 (less than Call Threshold Level)	$0
Final Valuation Date	Underlying Asset A: $39.00 (equal to or greater than Call Threshold Level)   Underlying Asset B: 1,400 (less than Call Threshold Level and Downside Threshold)	$1,000 x (1 + Underlying Return of the Least Performing Underlying Asset) = $1,000 x [$1 + (-60%)] = $1,000 x 0.40 = $400 (Payment at Maturity)
	Total Payment	$400.00 (60.00% loss)

Because the Notes are not subject to an automatic call and the final level of Underlying Asset B is less than its downside threshold, you will be exposed to the underlying return of the least performing underlying asset and at maturity UBS will pay you $400.00 per Note, a loss on the Notes of 60.00%.

We make no representation or warranty as to which of the underlying assets will be the least performing underlying asset for the purposes of calculating your actual payment at maturity.

Investing in the Notes involves significant risks. The Notes differ from ordinary debt securities in that UBS is not necessarily obligated to repay the full amount of your initial investment. If the Notes are not subject to an automatic call, you may lose a significant portion or all of your initial investment. Specifically, if the Notes are not subject to an automatic call and the final level of any underlying asset is less than its downside threshold, you will lose a percentage of your principal amount equal to the underlying return of the least performing underlying asset and, in extreme situations, you could lose all of your initial investment.

You will be exposed to the market risk of each underlying asset on each observation date, including the final valuation date, and any decline in the level of one underlying asset may negatively affect your return and will not be offset or mitigated by a lesser decline or any potential increase in the level of any other underlying asset. Any payment on the Notes, including any payments in respect of an automatic call or any repayment of principal, is subject to the creditworthiness of UBS. If UBS were to default on its payment obligations, you may not receive any amounts owed to you under the Notes and you could lose all of your initial investment.

Information About the Underlying Assets

All disclosures contained in this document regarding each underlying asset for the Notes are derived from publicly available information. UBS has not conducted any independent review or due diligence of any publicly available information with respect to any underlying asset. You should make your own investigation into each underlying asset.

Included on the following pages is a brief description of each underlying asset. This information has been obtained from publicly available sources. Set forth below is a table that provides the quarterly closing high and quarterly closing low for each underlying asset. The information given below is for the specified calendar quarters. We obtained the closing level information set forth below from Bloomberg Professional^® service (“Bloomberg”) without independent verification. You should not take the historical levels of the underlying assets as an indication of future performance.

The underlying equity is registered under the Securities Act of 1933, the Securities Exchange Act of 1934 and/or the Investment Company Act of 1940, each as amended. Companies with securities registered with the SEC are required to file financial and other information specified by the SEC periodically. Information filed by the underlying equity issuer with the SEC can be reviewed electronically through a website maintained by the SEC. The address of the SEC’s website is http://www.sec.gov. Information filed with the SEC by the underlying equity issuer can be located by reference to its SEC file number provided below. In addition, information filed with the SEC can be inspected and copied at the Public Reference Section of the SEC, 100 F Street, N.E., Room 1580, Washington, D.C. 20549. Copies of this material can also be obtained from the Public Reference Section, at prescribed rates.

iShares^® MSCI Emerging Markets ETF

We have derived all information contained herein regarding the iShares^® MSCI Emerging Markets ETF (the “EEM Fund”) from publicly available information. Such information reflects the policies of, and is subject to changes by, BlackRock Fund Advisors (“BFA”), the investment advisor of the EEM Fund. UBS has not undertaken an independent review or due diligence of any publicly available information with respect to the EEM Fund.

The EEM Fund is one of the separate investment portfolios that constitute the iShares, Inc. The EEM Fund seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI Emerging Markets Index (the “target index”). The EEM Fund will generally invest at least 90% of its assets in the securities of the target index and in American Depositary Receipts or Global Depositary Receipts based on securities of the target index. The EEM Fund may invest the remainder of its assets in other securities, including securities not in the target index, but which BFA believes will help the EEM Fund track the target index, and in other investments, including futures contracts, options on futures contracts, other types of options and swaps related to its target index, as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

BFA uses a representative sampling strategy to manage the EEM Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of the securities included in the target index that collectively has an investment profile similar to the target index. The securities selected are expected to have, in the aggregate, investment characteristics (based on market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the target index. The EEM Fund may or may not hold all of the securities that are included in the target index.

The EEM Fund will not concentrate its investments (i.e., hold 25% or more of its total assets in the stocks of a particular industry or group of industries), except that, to the extent practicable, the EEM Fund will concentrate its investments to approximately the same extent that the target index concentrates in the stocks of such particular industry or group of industries. The target index was developed by MSCI Inc. (“MSCI”) and is calculated, maintained and published by MSCI Inc. MSCI is under no obligation to continue to publish, and may discontinue or suspend the publication of the target index at any time. The target index has been developed by MSCI as an equity benchmark for international stock performance, and is designed to measure equity market performance in the global emerging markets.

Under new continuous listing standards adopted by NYSE Arca (the “Exchange”), the EEM Fund’s primary exchange, which went into effect on October 1, 2017, the EEM Fund is required to confirm on an ongoing basis that the components of the target index satisfy the Exchange’s listing requirements. In the event that the target index does not comply with the Exchange’s listing requirements, the EEM Fund will be required to rectify such non-compliance by requesting that the target index’s developer and sponsor, MSCI, modify the target index, adopting a new index or obtaining relief from the SEC. Failure to rectify this non-compliance may result in the EEM Fund being delisted by the Exchange.

As of December 31, 2018, ordinary operating expenses of the EEM Fund are expected to accrue at an annual rate of 0.67% of the EEM Fund’s average daily net asset value. Expenses of the EEM Fund reduce the net value of the assets held by the EEM Fund and, therefore, reduce the value of the shares of the EEM Fund.

As of August 31, 2018, the EEM Fund held stocks from the following 24 emerging markets: Brazil, Chile, China, Colombia, the Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Malaysia, Mexico, Pakistan, Peru, the Philippines, Poland, Qatar, Russia, South Africa, South Korea, Taiwan, Thailand, Turkey and the United Arab Emirates.

As of December 31, 2018, the EEM Fund’s held stocks in the following industry sectors: Financials (24.67%), Information Technology (14.19%), Communication (14.07%), Consumer Discretionary (10.43%), Energy (7.94%), Materials (7.65%), Consumer Staples (6.70%), Industrials (5.51%), Real Estate (3.00%), Health Care (2.81%), Utilities (2.66%) and Cash and/or Derivatives (0.36%).

Information filed by iShares, Inc. with the SEC can be found by reference to its SEC file numbers: 033-97598 and 811-09102 or its CIK Code: 0000930667. Shares of the EEM Fund are listed on the NYSE Arca under ticker symbol “EEM.”

Information from outside sources is not incorporated by reference in, and should not be considered part of, this document or any document incorporated herein by reference. UBS has not conducted any independent review or due diligence of any publicly available information with respect to the EEM Fund.

Historical Information

The following table sets forth the quarterly closing high and quarterly closing low for the EEM Fund, based on the daily closing levels as reported by Bloomberg, without independent verification. UBS has not conducted any independent review or due diligence of publicly available information obtained from Bloomberg. The closing level of the EEM Fund on January 28, 2019 was $41.76 (its “hypothetical initial level”). The actual initial level will be the closing level of the EEM Fund on the trade date. Past performance of the EEM Fund is not indicative of the future performance of the EEM Fund.

EURO STOXX 50^® Index

We have derived all information regarding the EURO STOXX 50^® Index (“SX5E”) contained in this document, including without limitation, its make-up, method of calculation and changes in its components from publicly available information. Such information reflects the policies of, and is subject to change by STOXX Limited (its “index sponsor” or “STOXX Limited”).

SX5E is published by STOXX Limited, but STOXX Limited has no obligation to continue to publish SX5E, and may discontinue publication of SX5E at any time. SX5E is determined, comprised and calculated by STOXX Limited without regard to the Notes.

As discussed more fully in the index supplement under “Non-U.S. Indices - EURO STOXX 50^® Index”, SX5E covers 50 stocks of market sector leaders mainly from 11 Eurozone countries: Austria, Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Portugal and Spain. SX5E captures a selection of the largest stocks among the 19 EURO STOXX regional Supersector indices. The largest stocks within those indices are added to the selection list until coverage is approximately 60% of the free float market capitalization of the corresponding EURO STOXX Total Market Index (the “EURO STOXX TMI”) Supersector Index and from that selection list the 50 stocks are selected. SX5E universe is defined as all components of the 19 EURO STOXX Regional Supersector indices. The EURO STOXX Supersector indices represent the Eurozone portion of the STOXX 600 Supersector indices, which contain the 600 largest stocks traded on the major exchanges of 18 European countries. Each component’s weight is capped at 10% of SX5E’s total free-float market capitalization.

Information from outside sources is not incorporated by reference in, and should not be considered part of, this document or any document incorporated herein by reference. UBS has not conducted any independent review or due diligence of any publicly available information with respect to SX5E.

Historical Information

The following table sets forth the quarterly closing high and quarterly closing low for SX5E based on the daily closing levels as reported by Bloomberg, without independent verification. UBS has not conducted any independent review or due diligence of publicly available information obtained from Bloomberg. The closing level of the SX5E on January 28, 2019 was 3,137.27 (its “hypothetical initial level”). The actual initial level will be the closing level of SX5E on the trade date. Past performance of SX5E is not indicative of the future performance of SX5E.

Correlation of the Underlying Assets

The graph below illustrates the daily performance of the iShares^® MSCI Emerging Markets ETF and the EURO STOXX 50^® Index from January 1, 2009 through January 28, 2019. For comparison purposes, each underlying asset has been normalized to have a closing level of 100 on January 1, 2009 by dividing the closing level of that underlying asset on each trading day by the closing level of that underlying asset on January 1, 2009 and multiplying by 100. We obtained the closing levels used to determine the normalized closing levels set forth below from Bloomberg, without independent verification.

The closer the relationship of the daily returns of the underlying assets over a given period, the more positively correlated those underlying assets are. The lower (or more negative) the correlation among the underlying assets, the less likely it is that those underlying assets will move in the same direction and therefore, the greater the potential for one of those underlying assets to close below its call threshold level on any observation date and below its downside threshold on the final valuation date. This is because the less positively correlated the underlying assets are, the greater the likelihood that at least one of the underlying assets will decrease in value. However, even if the underlying assets have a higher positive correlation, one or more of the underlying assets might close below its call threshold level on any observation date and below its downside threshold on the final valuation date, as the underlying assets may decrease in value together. Although the correlation of the underlying assets’ performance may change over the term of the Notes, the correlations referenced in setting the terms of the Notes are calculated using UBS’ internal models at the time when the terms of the Notes are set and are not derived from the daily returns of the underlying assets over the period set forth below. A higher call return rate is generally associated with lower correlation of the underlying assets, which reflects a greater potential that the Notes will not be subject to an automatic call and that you will suffer a loss on your investment at maturity. See “Key Risks — A higher call return rate or lower downside thresholds or call return rates may reflect greater expected volatility of each underlying asset, and greater expected volatility generally indicates an increased risk of loss at maturity”, “— You are exposed to the market risk of each underlying asset” and “—Because the Notes are linked to the least performing underlying asset, you are exposed to a greater risk of not receiving the call return and losing a significant portion or all of your initial investment at maturity than if the Notes were linked to fewer underlying assets” herein.

Past performance of the underlying assets is not indicative of the future performance of the underlying assets.

 

What are the Tax Consequences of the Notes?

The U.S. federal income tax consequences of your investment in the Notes are uncertain. There are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as the Notes. Some of these tax consequences are summarized below, but we urge you to read the more detailed discussion in “Material U.S. Federal Income Tax Consequences”, including the section “—Securities Treated as Prepaid Derivatives or Prepaid Forwards”, in the accompanying product supplement and to discuss the tax consequences of your particular situation with your tax advisor. This discussion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), final, temporary and proposed U.S. Treasury Department (the “Treasury”) regulations, rulings and decisions, in each case, as available and in effect as of the date hereof, all of which are subject to change, possibly with retroactive effect. Tax consequences under state, local and non-U.S. laws are not addressed herein. No ruling from the U.S. Internal Revenue Service (the “IRS”) has been sought as to the U.S. federal income tax consequences of your investment in the Notes, and the following discussion is not binding on the IRS.

U.S. Tax Treatment. Pursuant to the terms of the Notes, UBS and you agree, in the absence of a statutory or regulatory change or an administrative determination or judicial ruling to the contrary, to characterize the Notes as prepaid derivative contracts with respect to the underlying assets. If your Notes are so treated, you should generally recognize capital gain or loss upon the taxable disposition 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. Subject to the constructive ownership rules (discussed below), such gain or loss should generally be long-term capital gain or loss if you have held your Notes for more than one year (otherwise such gain or loss should be short-term capital gain or loss if held for one year or less). The deductibility of capital losses is subject to limitations.

Based on certain factual representations received from us, our counsel, Cadwalader, Wickersham & Taft LLP, is of the opinion that 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 (including possible treatment as a “constructive ownership transaction”), such that the timing and character of your income from the Notes could differ materially and adversely from the treatment described above, as described further under “Material U.S. Federal Income Tax Consequences”, including the section “— Securities Treated as Prepaid Derivatives or Prepaid Forwards”, in the accompanying product supplement.

Section 1260. Because the underlying equity would be treated as a “pass-thru entity” for purposes of Section 1260 of the Code, it is possible that the Notes could be treated as a constructive ownership transaction under Section 1260 of the Code. If the Notes were treated as a constructive ownership transaction, certain adverse U.S. federal income tax consequences could apply (i.e., all or a portion of any long-term capital gain that you recognize upon the taxable disposition of your Notes could be recharacterized as ordinary income, and you could be subject to an interest charge on any deferred tax liability with respect to such recharacterized gain). We urge you to read the discussion concerning the possible treatment of the Notes as a constructive ownership transaction under “Material U.S. Federal Income Tax Consequences — Securities Treated as Prepaid Derivatives or Prepaid Forwards — Section 1260” in the accompanying product supplement.

Notice 2008-2. In 2007, the IRS released a notice that may affect the taxation of holders of the Notes. According to Notice 2008-2, the IRS and the Treasury are actively considering whether the holder of an instrument similar to 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 Treasury are also considering other relevant issues, including whether additional gain or loss from such instruments should be treated as ordinary or capital, whether non-U.S. 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, discussed above, should be applied to such instruments. Both U.S. and non-U.S. holders are urged to consult their tax advisors concerning the significance, and the potential impact, of the above considerations.

Section 1297. We will not attempt to ascertain whether any underlying constituent issuer would be treated as a “passive foreign investment company” (a “PFIC”) within the meaning of Section 1297 of the Code. If any such entity were so treated, certain adverse U.S. federal income tax consequences might apply upon the taxable disposition of a Note. You should refer to information filed with the SEC or the equivalent governmental authority by such entities and consult your tax advisor regarding the possible consequences to you if any such entity is or becomes a PFIC.

Medicare Tax on Net Investment Income. U.S. holders that are individuals, estates, and certain trusts are subject to an additional 3.8% tax on all or a portion of their “net investment income,” which may include any income or gain realized with respect to the Notes, to the extent of their net investment income 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. The 3.8% Medicare tax is determined in a different manner than the income tax. You should consult your tax advisors as to the consequences of 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 an applicable threshold. Significant penalties can apply if a U.S. holder is required to disclose its Notes and fails to do so.

Non-U.S. Holders. Subject to Section 871(m) of the Code and “FATCA”, discussed below, if you are a non-U.S. holder you should generally not be subject to U.S. withholding tax with respect to payments on your Notes or 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 non-U.S. status (by providing us (and/or the applicable withholding agent) with a fully completed and duly executed applicable IRS Form W-8). Subject to Section 871(m) of the Code, discussed below, gain from the taxable disposition of a Note generally should not be subject to U.S. tax unless (i) such gain is effectively connected with a trade or business conducted by the non-U.S. holder in the U.S., (ii) the non-U.S. holder is a non-resident alien individual and is present in the U.S. for 183 days or more during the taxable year of such taxable disposition and certain other conditions are satisfied or (iii) the non-U.S. holder has certain other present or former connections with the U.S.

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. However, the IRS has issued guidance that states that the Treasury and the IRS intend to amend the effective dates of the Treasury regulations to provide that withholding on dividend equivalents paid or deemed paid will not apply to specified equity-linked instruments that are not delta-one specified equity-linked instruments and are issued before January 1, 2021.

Based on our determination that the Notes are not “delta-one” with respect to any underlying asset or any Underlying constituent, our counsel is of the opinion that the Notes should not be delta-one specified equity-linked instruments and thus 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 underlying assets, Underlying constituents 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 you enter, or have entered, into certain other transactions in respect of the underlying assets, Underlying constituents or the Notes. If you enter, or have entered, into other transactions in respect of the underlying assets, Underlying constituents or the Notes, you should consult your tax advisor regarding the application of Section 871(m) of the Code to your Notes in the context of your 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.

Foreign Account Tax Compliance Act. 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 of 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”, will not apply to gross proceeds on a sale or disposition, and will apply to certain foreign passthru payments only to the extent that such payments are made after the date that is two years after 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 tax advisors about the application of FATCA, in particular if they may be classified as financial institutions (or if they hold their Notes through a foreign entity) under the FATCA rules.

Proposed Legislation. In 2007, legislation was introduced in Congress that, if it had been enacted, would have required holders of Notes purchased after the bill was enacted to accrue interest income over the term of the Notes despite the fact that there will be no interest payments over the term of the Notes.

Furthermore, in 2013, the House Ways and Means Committee released in draft form certain proposed legislation relating to financial instruments. If it had been enacted, the effect of this legislation generally would have been to require instruments such as the Notes to be marked to market on an annual basis with all gains and losses to be treated as ordinary, subject to certain exceptions.

It is not possible to predict whether any similar or identical bills will be enacted in the future, or whether any such bill would affect the tax treatment of your Notes. You are urged to consult your tax advisor regarding the possible changes in law and their possible impact on the tax treatment of your Notes.

Both U.S. and non-U.S. holders are urged to consult their tax advisors concerning the application of U.S. federal income tax laws to their particular situations, as well as any tax consequences of the purchase, beneficial ownership and disposition of the Notes arising under the laws of any state, local, non-U.S. or other taxing jurisdiction (including those of the underlying constituent issuers).

Supplemental Plan of Distribution (Conflicts of Interest); Secondary Markets (if any)

We will agree to sell to UBS Securities LLC and UBS Securities LLC will agree to purchase, all of the Notes at the issue price to the public less the underwriting commissions indicated on the cover hereof. UBS Securities LLC will agree to resell all of the Notes to Raymond James & Associates, Inc. and will pay all of the commissions it receives to Raymond James & Associates, Inc. UBS Securities LLC will also pay Raymond James & Associates, Inc. a structuring fee of $4.00 per Note with respect to some or all of the Notes. This amount will be deducted from amounts remitted to UBS.

Conflicts of Interest — UBS Securities LLC is an affiliate of UBS and, as such, has a “conflict of interest” in this offering within the meaning of Financial Industry Regulatory Authority, Inc. (“FINRA”) Rule 5121. In addition, UBS will receive the net proceeds (excluding the applicable underlying commissions and fees) from the initial public offering of the Notes, thus creating an additional conflict of interest within the meaning of FINRA Rule 5121. Consequently, the offering is being conducted in compliance with the provisions of FINRA Rule 5121. UBS Securities LLC is not permitted to sell Notes in this offering to an account over which it exercises discretionary authority without the prior specific written approval of the account holder.

UBS Securities LLC and its affiliates may offer to buy or sell the Notes in the secondary market (if any) at prices greater than UBS’ internal valuation — The value of the Notes at any time will vary based on many factors that cannot be predicted. However, the price (not including UBS Securities LLC’s or any affiliate’s customary bid-ask spreads) at which UBS Securities LLC or any affiliate would offer to buy or sell the Notes immediately after the trade date in the secondary market is expected to exceed the estimated initial value of the Notes as determined by reference to our internal pricing models. The amount of the excess will decline to zero on a straight line basis over a period ending no later than 6 months after the trade date, provided that UBS Securities LLC may shorten the period based on various factors, including the magnitude of purchases and other negotiated provisions with selling agents. Notwithstanding the foregoing, UBS Securities LLC and its affiliates are not required to make a market for the Notes and may stop making a market at any time. For more information about secondary market offers and the estimated initial value of the Notes, see “Key Risks — Fair value considerations” and “Key Risks — Limited or no secondary market and secondary market price considerations” herein.

Prohibition of Sales to EEA Retail Investors — The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU, as amended (“MiFID II”); (ii) a customer within the meaning of Directive 2002/92/EC, as amended, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC, as amended. Consequently no key information document required by Regulation (EU) No 1286/2014, as amended (the “PRIIPs Regulation”), for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.
