UBS AG $14,487,000 Bearish Barrier Early Redeemable Market Linked Notes with Daily Barrier Observation

Linked to the S&P 500^® Index due December 31, 2020

Investment Description

UBS AG Bearish Barrier Early Redeemable Market Linked Notes with Daily Barrier Observation (the “Notes”) are unsubordinated, unsecured debt securities issued by UBS AG (“UBS” or the “issuer”) linked to the performance of the S&P 500^® Index (the “underlying asset”). The amount you receive at maturity will be based on the performance of the underlying asset over the term of the Notes. The Notes will be redeemed early if a barrier event occurs, meaning that the closing level of the underlying asset on any trading day during the observation period (including the final valuation date) is less than the lower barrier. If the Notes are redeemed early because a barrier event occurs, UBS will pay on the applicable call payment date following such date a cash payment per Note equal to your principal amount plus a return equal to the conditional return, and no further payments will be owed to you under the Notes. If the Notes are not redeemed early, because a barrier event does not occur, and the closing level of the underlying asset on the final valuation date (the “final level”) is equal to or greater than the initial level, UBS will pay you a cash payment per Note at maturity equal to the principal amount plus a return equal to the conditional return. If, however, the final level is less than the initial level, UBS will pay you an amount in cash per Note at maturity equal to the principal amount plus a return equal to the absolute value of the “underlying return”, which is the percentage change in the closing level of the underlying asset from the trade date to the final valuation date. If the Notes are not redeemed early, because a barrier event does not occur, and the final level is less than the initial level, your return on the Notes is limited to 25.00% due to the inclusion of the lower barrier. Investing in the Notes involves significant risks. The Notes do not pay interest and your return on the Notes is limited to 1% if the Notes are redeemed early because a barrier event occurs or, if the Notes are not redeemed early because a barrier event does not occur and the final level is equal to or greater than the initial level. The repayment of principal applies only if the Notes are held to maturity. 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 riskier than conventional debt instruments. The issuer will not make interest payments. You should not purchase the Notes if you do not understand or are not comfortable with the 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 in 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. The Notes will not be listed or displayed on any securities exchange or any electronic communications network.

Final Terms

Investment Timeline

 

Trade Date		The initial level is observed and the final terms of the Notes are set.
¯
Each Trading Day During the Observation Period		If a barrier event occurs, the Notes will be redeemed early and UBS will pay you on the call settlement date a cash payment per Note equal to: $1,000 × (1 + Conditional Return)
¯
Maturity Date		The final level is observed on the final valuation date and the absolute value of the underlying return is calculated. If a barrier event has not occurred, so the Notes are not redeemed early, and the final level is equal to or greater than the initial level, UBS will pay you an amount in cash per Note on the maturity date equal to: $1,000 × (1 + Conditional Return) If a barrier event has not occurred, so the Notes are not redeemed early, and the final level is less than the initial level, UBS will pay you an amount in cash per Note on the maturity date equal to: $1,000 × (1 + absolute value of the Underlying Return)

Investing in the Notes involves significant risks. 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.

Key Risks

An investment in the Notes involves risks. Some of the key risks that apply to the Notes are summarized here, but we urge you to read the more detailed explanation of risks relating to the Notes generally 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.

¨

The stated payout from the issuer 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 early redemption or maturity in the secondary market, you may have to sell them at a loss relative to your initial investment irrespective of the performance of the underlying asset. All payments on the Notes are subject to the creditworthiness of UBS.

¨

Your potential return on the Notes is limited — The Notes are designed for investors who believe that the closing level will decline over the term of the Notes, but not to a level that is less than the lower barrier and any potential return on the Notes is limited to the percentage difference between the lower barrier and the initial level or the conditional return. If a barrier event does not occur, so the Notes are not redeemed early, and the final level is less than the lower barrier, your ability to participate in the decline of the underlying asset and your potential return are limited by the lower barrier and in no event will any payment on the Notes exceed the maximum payment at maturity per Note. Additionally, if a barrier event occurs, the Notes will be redeemed early and you will receive a cash payment on the call settlement date equal to the principal amount of your Notes plus the conditional return. Similarly, if a barrier event does not occur, so the Notes are not redeemed early, and the final level is equal to or greater than the initial level, you will receive a cash payment on the maturity date equal to the principal amount of your Notes plus the conditional return. In both of the preceding scenarios, your return will be limited to, and will not exceed, the conditional return. Further, even if a barrier event does not occur, so the Notes are not redeemed early, the underlying return is negative and the final level is equal to or greater than the lower barrier, the absolute value of the underlying return may result in a return on the Notes that is less than the conditional return.

¨

Reinvestment risk — The Notes will be redeemed early if a barrier event occurs, meaning the closing level is less than the lower barrier on any trading day during the observation period (including the final valuation date). Because a barrier event could occur on any trading day during the observation period, the term of your investment may be limited. In the event that the Notes are redeemed early due to a barrier event, there is no guarantee that you would be able to reinvest the proceeds at a comparable return 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 hedging costs built into the price of the new securities.

¨

Bearish exposure to the underlying asset – Unlike a hypothetical direct investment in the underlying asset or the stocks comprising the underlying asset (the “underlying equity constituents”), which would be positively correlated to the return of the underlying asset or underlying equity constituents, the return on your Notes will be limited to the conditional return if either the Notes are redeemed early due to a barrier event or the Notes are not redeemed early and the final level is equal to or greater than the initial level. Your return on the Notes will be maximized if the level of the underlying asset declines during the term of the Notes so long as a barrier event does not occur during the observation period.

¨

The probability that a barrier event will occur and that the Notes will be redeemed early or that the final level will be equal to or greater than the initial level will depend on the volatility of the underlying asset — The economic terms for the Notes, including the conditional return and lower barrier, are based, in part, on the expected volatility of the 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 the underlying asset. The greater the expected volatility of the underlying asset as of the trade date, the higher the expectation is as of that date that a barrier event will occur and that the Notes will be redeemed early or that, if the Notes are not redeemed early because a barrier event has not occurred, the final level will be equal to or greater than the initial level. The volatility of the underlying asset can change significantly over the term of the Notes. The level of the underlying asset could rise or fall sharply, which could result in an early redemption occurring during the observation period or the final level being equal to or greater than the initial level. You should be willing to accept the potential to lose any downside participation in the underlying asset at maturity and of receiving a percentage return on your Notes that is equal to or less than the conditional return.

¨

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

¨

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 at maturity, 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 is directly linked to the performance of the underlying asset and indirectly linked to the performance of the underlying equity constituents, and will depend on whether a barrier event occurs and the Notes are redeemed early and, if a barrier event does not occur and the Notes are not redeemed early, whether the underlying return is positive or negative. The level of the underlying asset can rise or fall sharply due to factors specific to the underlying equity constituents, such as stock 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 market volatility and levels, interest rates and economic and political conditions.

¨

Fair value considerations.

¨

The issue price you pay for the Notes exceeds their estimated initial value — The issue price you pay for the Notes exceeds their estimated initial value as of the trade date due to the inclusion in the issue price of any underwriting discount, hedging costs, issuance costs and projected profits. As of the close of the relevant markets on the trade date, we have determined the estimated initial value of the Notes by reference to our internal pricing models and it is set forth in this pricing supplement. The pricing models used to determine the estimated initial value of the Notes incorporate certain variables, including the level and volatility of the underlying asset, any expected dividends on the underlying equity constituents, 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. Any underwriting discount, 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 is 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 pricing the Notes on 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 any underwriting discount, 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 Financial Services Inc. and UBS Securities LLC reflect this temporary positive differential on their 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 level of the underlying asset; the volatility of the underlying asset and its underlying equity constituents; any dividends paid on the underlying equity constituents; 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; the availability of comparable instruments; the creditworthiness of UBS; the then current bid-ask spread for the Notes. 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 any underwriting discount, 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.

¨

Owning the Notes is not the same as owning the underlying equity constituents and the absolute return feature is not the same as taking a short position directly in the underlying equity constituents— The return on your Notes may not reflect the return you would realize if you actually owned the underlying equity constituents. For instance, because of the lower barrier, you will not benefit from any absolute value of the underlying return that exceeds the maximum payment at maturity per Note. Furthermore, you will not receive or be entitled to receive any dividend payments or other distributions paid on the underlying equity constituents during the term of the Notes, and any such dividends or distributions will not be factored into the calculation of any payment on your Notes. In addition, as an owner of the Notes, you will not have voting rights or any other rights that a holder of the underlying equity constituents may have. Further, even if a barrier event does not occur, so the Notes are not redeemed early, the underlying return is negative and the final level is equal to or greater than the lower barrier, the return on the Notes will not reflect the return you would realize if you actually took a short position directly in the underlying equity constituents. For example, to maintain a short position in an underlying equity constituent, you would have to pay dividend payments (if any) to the entity that lends you the underlying equity constituent for your short sale, and you could receive certain interest payments (the short interest rebate) from the lender.

¨

There can be no assurance that the investment view implicit in the Notes will be successful — It is impossible to predict whether the level of the underlying asset will rise or fall and no there can be no assurance that a barrier event will not occur, meaning the Notes will not be redeemed early, or that the final level will be less than the initial level. Even if no barrier event occurs, so the Notes are not redeemed early, and the final level is less than the initial level, the absolute value of the underlying return may not result in a return on the Notes in excess of the conditional return. The level of the underlying asset will be influenced by complex and interrelated political, economic, financial and other factors that affect the issuers of the underlying equity constituents (the “underlying constituent issuers”). You should be willing to accept the risks of owning equities in general and the underlying equity constituents in particular.

¨

The underlying asset reflects price return, not total return — The return on your Notes is based on the performance of the underlying asset, which reflects the changes in the market prices of the underlying equity constituents. It is not, however, linked to a “total return” index or strategy, which, in addition to reflecting those price returns, would also reflect any dividends or distributions paid on the underlying equity constituents. The return on your Notes will not include such a total return feature or dividend component.

¨

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

¨

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 asset. 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 market value of, or the amount payable on, your Notes.

¨

Potential UBS impact on price — Trading or transactions by UBS and/or its affiliates in the underlying equity constituents, listed and/or over-the-counter options, futures or other instruments with returns linked to the performance of the underlying asset or any underlying equity constituent may adversely affect the performance and, therefore, the market value of, and the amount payable on, the Notes.

¨

Potential conflict of interest — UBS and its affiliates may engage in business with 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. The calculation agent can postpone the determination of the terms of the Notes on the trade date and the closing level on any trading day during the observation period (including the final valuation date), if a market disruption event occurs and is continuing on that day. As UBS determines the economic terms of the Notes, including the conditional return and lower barrier, and such terms include any underwriting discount, 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.

¨

Dealer incentives — UBS and its affiliates act in various capacities with respect to the Notes. We and our affiliates may act as a principal, agent or dealer in connection with the sale of the Notes. Such affiliates, including the sales representatives, 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. We will pay a total underwriting compensation in an amount equal to any underwriting discount listed on the cover hereof per Note to any of our affiliates acting as agents or dealers in connection with the distribution of the Notes. 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 asset 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' 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' 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' 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 Notes?” herein and “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement.

The examples and table below illustrate the payment 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 analysis):

Term:	20 months
Initial Level:	2,700
Conditional Return:	1.00%
Lower Barrier:	2,025 (equal to Initial Level minus 25.00% of the Initial Level)
Maximum Payment Amount	$1,250.00 per Note

Example 1 — A barrier event occurs during the observation period so the Notes are redeemed early.

Because a barrier event occurs, meaning the closing level of the underlying asset is less than the lower barrier on a trading day during the observation period, the Notes will be redeemed early and UBS will pay you an amount in cash per Note on the call payment date equal to the principal amount plus a return equal to the conditional return, calculated as follows:

$1,000 x (1 + 1.00%)

= $1,010 per Note (a 1.00% total return).

Example 2 — A barrier event does not occur during the observation period, so the Notes are not redeemed early, and the underlying return is 10%.

Though the Notes are not redeemed early because a barrier event does not occur, because the final level is equal to or greater than the initial level, UBS will pay you an amount in cash per Note on the maturity date equal to the principal amount plus a return equal to the conditional return, calculated as follows:

$1,000 x (1 + 1.00%)

= $1,010 per Note (a 1.00% total return).

Example 3 — A barrier event does not occur during the observation period, so the Notes are not redeemed early, and the underlying return is -0.50%.

Because a barrier event does not occur, the Notes are not redeemed early and the final level of the underlying asset has depreciated relative to the initial level, UBS will pay you an amount in cash per Note on the maturity date equal to the principal amount plus a return equal to the absolute value of the underlying return, calculated as follows:

$1,000 x (1 + |-0.50%|)

= $1,005 per Note (a 0.50% total return).

In this scenario, because the absolute value of the underlying return is less than the conditional return, your return is less than it would have been if either the Notes were redeemed early due to a barrier event or the final level was equal to or greater than the initial level.

Example 4 — A barrier event does not occur during the observation period, so the Notes are not redeemed early, and the underlying return is -20%.

Because a barrier event does not occur, the Notes are not redeemed early and the final level of the underlying asset has depreciated relative to the initial level, UBS will pay you an amount in cash per Note on the maturity date equal to the principal amount plus a return equal to the absolute value of the underlying return, calculated as follows:

$1,000 x (1 + |-20.00%|)

= $1,200 per Note (a 20.00% total return).

Table 1: Return on the Notes if a barrier event does not occur, so the Notes are not redeemed early.

Information About the Underlying Asset

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

Included on the following pages is a brief description of the 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 the underlying asset. We obtained the closing level information set forth below from Bloomberg Professional^® service (“Bloomberg”) without independent verification. You should not take the historical prices of the underlying asset as an indication of future performance.

S&P 500^® Index

We have derived all information regarding the S&P 500^® Index (“SPX”) 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 S&P Dow Jones Indices LLC (its “index sponsor” or “S&P Dow Jones”).

SPX is published by S&P Dow Jones, but S&P Dow Jones has no obligation to continue to publish SPX, and may discontinue publication of SPX at any time. SPX is determined, comprised and calculated by S&P Dow Jones without regard to the Notes.

As discussed more fully in the index supplement under the heading “Underlying Indices and Underlying Index Publishers — S&P 500^® Index”, SPX is intended to provide an indication of the pattern of common stock price movement. The calculation of the value of SPX is based on the relative value of the aggregate market value of the common stock of 500 companies as of a particular time compared to the aggregate average market value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943. Eleven main groups of companies comprise SPX, with the percentage weight of each group in the index as a whole as of March 29, 2019 as follows: Information Technology (21.2%), Health Care (14.6%), Financials (12.7%), Consumer Discretionary (10.1%), Communication Services (10.1%), Industrials (9.5%), Consumer Staples (7.3%), Energy (5.4%), Utilities (3.3%), Real Estate (3.1%) and Materials (2.6%). As of September 28, 2018, the index sponsor broadened the current Telecommunication Services Sector and renamed it Communication Services. The renamed Sector includes the existing telecommunication companies, as well as companies selected from the Consumer Discretionary Sector previously classified under the Media Industry Group and the Internet & Direct Marketing Retail Sub-Industry, along with select companies previously classified in the Information Technology Sector. Effective February 20, 2019, company additions to the underlying asset should have an unadjusted company market capitalization of $8.2 billion or more (an increase from the previous requirement of an unadjusted company market capitalization of $6.1 billion or more).

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 SPX.

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” in the accompanying product supplement and 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”) and 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.

Additionally, the discussion herein and in the accompanying product supplement does not address the consequences to taxpayers subject to special tax accounting rules under Section 451(b) of the Code.

U.S. Tax Treatment. Your Notes should be treated as contingent payment debt instruments (“CPDI”) subject to taxation under the “noncontingent bond method”. If your Notes are so treated, you should generally, for each accrual period, accrue original issue discount (“OID”) equal to the product of (i) the “comparable yield” (adjusted for the length of the accrual period) and (ii) the “adjusted issue price” of the Notes at the beginning of the accrual period. This amount is ratably allocated to each day in the accrual period and is includible as ordinary interest income by a U.S. holder for each day in the accrual period on which the U.S. holder holds the CPDI, whether or not the amount of any payment is fixed or determinable in the taxable year. Thus, the noncontingent bond method will result in recognition of income prior to the receipt of cash.

In general, the comparable yield of a CPDI is equal to the yield at which we would issue a fixed rate debt instrument with terms and conditions similar to those of the CPDI, including the level of subordination, term, timing of payments, and general market conditions. In general, because similar fixed rate debt instruments issued by us are traded at a price that reflects a spread above a benchmark rate, the comparable yield is the sum of the benchmark rate on the issue date and the spread.

As the Notes have only a single contingent payment at upon early redemption or at maturity, the adjusted issue price of each Note at the beginning of each accrual period is equal to the issue price of the Note plus the amount of OID previously includible in the gross income of the U.S. holder in respect of prior accrual periods.

In addition to the determination of a comparable yield, the noncontingent bond method requires the construction of a projected payment schedule. The projected payment schedule includes the projected amounts for each contingent payment to be made under the CPDI that are adjusted to produce the comparable yield. We have determined that the comparable yield for the Notes is equal to 2.56% per annum, compounded semi-annually, with a projected payment at maturity of $1,043.33 based on an investment of $1,000.

Based on this comparable yield, if you are an initial holder that holds a Note until maturity and you calculate your taxes on a calendar year basis, we have determined that you would be required to report the following amounts as ordinary interest income from the Note, not taking into account any positive or negative adjustments you may be required to take into account based on actual payments on such Note:

Accrual Period	Interest Deemed to Accrue During Accrual Period (per $1,000 Note)	Total Interest Deemed to Have Accrued From Original Issue Date (per $1,000 Note) as of End of Accrual Period
April 30, 2019 through December 31, 2019	$17.12	$17.12
January 1, 2020 through December 31, 2020	$26.20	$43.33

A U.S. holder of the Notes is required to use our projected payment schedule to determine its interest accruals and adjustments, unless such holder determines that our projected payment schedule is unreasonable, in which case such holder must disclose its own projected payment schedule in connection with its U.S. federal income tax return and the reason(s) why it is not using our projected payment schedule. Neither the comparable yield nor the projected payment schedule constitutes a representation by us regarding the actual contingent amount, if any, that we will pay on a Note.

If the actual amounts of contingent payments are different from the amounts reflected in the projected payment schedule, a U.S. holder is required to make adjustments in its OID accruals under the noncontingent bond method described above when those amounts are paid. Accordingly, an adjustment arising from the contingent payment made at maturity that is greater than the assumed amount of such payment is referred to as a “positive adjustment”; such adjustment arising from the contingent payment at maturity that is less than the assumed amount of such payment is referred to as a “negative adjustment”. Any positive adjustment for a taxable year is treated as additional OID income of the U.S. holder. Any net negative adjustment reduces any OID on the Note for the taxable year that would otherwise accrue. Any excess is then treated as a current-year ordinary loss to the U.S. holder to the extent of OID accrued in prior years.

In general, a U.S. holder’s basis in a CPDI is increased by the projected contingent payments accrued by such holder under the projected payment schedule (as determined without regard to adjustments made to reflect differences between actual and projected payments) and the projected amount of any contingent payments previously made. Gain on the taxable disposition of a CPDI generally is treated as ordinary income. Loss, on the other hand, is treated as ordinary loss only to the extent of the U.S. holder’s prior net OID inclusions (i.e., reduced by the total net negative adjustments previously allowed to the U.S. holder as an ordinary loss) and capital loss to the extent in excess thereof. However, the deductibility of a capital loss realized on the taxable disposition of a Note is subject to limitations. Under the rules governing CPDI, special rules would apply to a person who purchases Notes at a price other than the adjusted issue price as determined for tax purposes.

A U.S. holder that purchases a Note for an amount other than the public offering price of the Note will be required to adjust its OID inclusions to account for the difference. These adjustments will affect the U.S. holder?s basis in the Note. Reports to U.S. holders may not include these adjustments. U.S. holders that purchase Notes at other than the issue price to public should consult their tax advisor regarding these adjustments.

Prospective investors should consult their tax advisor with respect to the application of the CPDI provisions to the Notes.

Based on certain factual representations received from us, our counsel, Cadwalader, Wickersham & Taft LLP, is of the opinion that your Notes should be treated in the manner described above.

Alternative Characterizations. 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 pursuant to some other characterization, such that the timing and character of your income from the Notes could differ materially and adversely from the treatment described above. In particular, the IRS might assert that the Notes should be treated as deemed to be redeemed and reissued on any rebalancing of the underlying asset or rollover of, or change to, the underlying equity constituents.

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

Specified Foreign Financial Assets. Certain U.S. holders that own “specified foreign financial assets” in excess of an applicable threshold may be subject to reporting obligations with respect to such assets with their tax returns, especially if such assets are held outside the custody of a U.S. financial institution. You are urged to consult your tax advisor as to the application of this legislation to your ownership of the Notes.

Non-U.S. Holders. Subject to “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 foreign status (by providing us (and/or the applicable withholding agent) with a fully completed and duly executed applicable IRS Form W-8). 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.

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 advisor 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.

As mentioned above, alternative characterizations of the Notes for U.S. federal income tax purposes are possible. Should an alternative characterization of the Notes cause payments with respect to the Notes to become subject to withholding tax, we (or the applicable withholding agent) will withhold tax at the applicable statutory rate and we will not make payments of any additional amounts.

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, including the portfolio interest rule, 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.

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

We have agreed to sell to UBS Securities LLC and UBS Securities LLC has agreed to purchase, all of the Notes at the issue price to the public less any underwriting discount indicated on the cover hereof. UBS Securities LLC has agreed to resell all of the Notes to UBS Financial Services Inc. at a discount from the issue price to the public equal to the underwriting discount indicated on the cover hereof.

Conflicts of Interest — Each of UBS Securities LLC and UBS Financial Services Inc. is an affiliate of UBS and, as such, has a “conflict of interest” in this offering within the meaning of the Financial Industry Regulatory Authority, Inc. (“FINRA”) Rule 5121. In addition, UBS will receive the net proceeds (excluding the underwriting discount) 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. Neither UBS Securities LLC nor UBS Financial Services Inc. is 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 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 5 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 intend, but 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 “— 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.

Validity of the Notes

In the opinion of Cadwalader, Wickersham & Taft LLP, as special counsel to the issuer, when the Notes offered by this pricing supplement have been executed and issued by the issuer and authenticated by the trustee pursuant to the indenture and delivered, paid for and sold as contemplated herein, the Notes will be valid and binding obligations of the issuer, enforceable against the issuer in accordance with their terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium, receivership or other laws relating to or affecting creditors' rights generally, and to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). This opinion is given as of the date hereof and is limited to the laws of the State of New York. Insofar as this opinion involves matters governed by Swiss law, Cadwalader, Wickersham & Taft LLP has assumed, without independent inquiry or investigation, the validity of the matters opined on by Homburger AG, Swiss legal counsel for the issuer, in its opinion dated October 29, 2018 filed on that date with the Securities and Exchange Commission as Exhibit 5.3 to the issuer's registration statement on Form F-3 (the "Registration Statement"). In addition, this opinion is subject to customary assumptions about the trustee's authorization, execution and delivery of the indenture and, with respect to the Notes, authentication of the Notes and the genuineness of signatures and certain factual matters, all as stated in the opinion of Cadwalader, Wickersham & Taft LLP dated October 29, 2018 filed on that date with the Securities and Exchange Commission as Exhibit 5.4 to the Registration Statement.
