President's letter

August 18, 2017

Dear Shareholder,

Many of the investment themes that have driven markets over the past several quarters are still in place—with some important differences having developed in the first half of 2017. Global markets continue to rise led by positive economic indicators, but are complicated by central bank actions to reverse the accommodative policies of the past several years. In the United States, the defining investment narrative of Donald Trump's presidency has shifted from having been unambiguously supportive at the beginning of his term to highly uncertain after the first six months. Financial markets in the developed world have recently enjoyed a very smooth growth path. However, potential eruptions of volatility could be spurred by central bank action in their return to a more normal policy stance; by risks posed by the gap between the market's expectation of pro-growth legislation and the reality of what lawmakers are able to deliver; or by unanticipated geopolitical events that have heretofore not significantly altered equity markets' upward march. At UBS Asset Management, we are constantly monitoring the investment landscape and we believe that the potential for a more uneven growth path makes diversification and long-term planning more pertinent for today's investors.

For central banks in the developed world, returning to normal policies from the highly accommodative measures instituted after the 2008—2009 financial crisis will likely be a delicate balancing act. Move too rapidly and central bank policy changes could dampen economic growth. On the other side, reluctance to move quickly enough could have the unintended effect of inflating a bubble in risk assets. While we believe that central banks will take a moderate and thoughtful approach to policy normalization, it remains to be seen how and when financial markets will find their way back to smooth functioning after having become accustomed to unorthodox central bank interventions. Coupled with ongoing uncertainties around the Trump administration's ability to implement pro-growth legislation in the United States, unsettled geopolitical concerns and some key elections in European countries, we believe that we are entering a new market phase. Asset prices and volatility could become increasingly dependent on the policy successes and failures of both central banks and national governments.

Against the backdrop of a policy-driven market, we see a shift toward portfolio manager skills playing a much greater role in generating returns for investors. As central banks move toward historical policy norms, we expect the price of equities to rise more slowly. But decelerating equity markets can also create value opportunities and skilled portfolio managers can use an investment's fundamental measures to exploit temporary price distortions and create excess returns. Active managers with a long-term view and the ability to look through short-term noise have the unique opportunity to find investments that can perform strongly, even if the overall market disappoints. We continue to believe that there are compelling opportunities across global asset classes and that the right strategies in the hands of skilled investment professionals have the power to deliver better investment outcomes for our clients. At UBS Asset Management, we embrace the responsibility of helping our clients meet their financial objectives and thank you for your continued trust in our skill and commitment to serve you.

The markets in review

The global economic expansion continues

The US economy continued to expand, albeit at a relatively modest pace, during the 12 months ended June 30, 2017. Looking back, the US Commerce Department reported that gross domestic product ("GDP") grew at a revised 2.2% seasonally adjusted annualized rate during the second quarter of 2016. GDP growth then improved to a revised 2.8% rate during the third quarter of 2016—the strongest reading since the first quarter of 2015. GDP growth then moderated to a revised 1.8% rate during the fourth quarter of 2016 and a 1.2% rate during the first quarter of 2017. Finally, second quarter 2017 GDP grew at a 2.6% rate based on the US Commerce Department's initial estimate.¹

Prior to the beginning of the reporting period, after taking its first step toward normalizing monetary policy in late 2015, the US Federal Reserve Board ("Fed") kept the federal funds rate unchanged until December 2016, when it increased rates by 0.25% to a range between 0.50% and 0.75%. After keeping rates unchanged at its first meeting in 2017, the Fed again raised rates 0.25% to a range between 0.75% and 1.00% at its meeting in March 2017, and then to a range between 1.00% and 1.25% at its meeting in June 2017. In its statement following the June meeting, the Fed indicated that it may begin to reduce its balance sheet later in the year, saying, "The Committee currently expects to begin implementing a balance sheet normalization program this year, provided that the economy evolves broadly as anticipated."

From a global perspective, the International Monetary Fund's ("IMF") April 2017 World Economic Outlook Update said, "Global economic activity is picking up with a long-awaited cyclical recovery in investment, manufacturing, and trade...If confidence and market sentiment remain strong, short-term growth could indeed surprise on the upside. But these positive developments should not distract from binding structural impediments to a stronger recovery and a balance of risks that remains tilted to the downside, especially over the medium term." From a regional perspective, the IMF projects 2017 growth in the eurozone will be 1.7%, the same as in 2016. Japan's economy is forecast to grow 1.2% in 2017, compared to 1.0% in 2016. Finally, the IMF projects that overall growth in emerging markets countries will increase to 4.5% in 2017, versus 4.1% in 2016.

Global equities generated strong results

While there were periods of volatility, the global equity market generated strong results during the reporting period as a whole. After a strong start, equites then experienced a setback in October 2016 given uncertainties surrounding the US elections. However, US equities rallied sharply following the elections given expectations for improving growth under the Trump administration. International equities largely followed the same pattern, as they rallied amid signs of improving growth and continued monetary policy accommodation. All told, the US stock market, as measured by the S&P 500 Index,² gained 17.90% for the 12 months ended June 30, 2017. International developed equities, as measured by the MSCI EAFE Index (net),³ rose 20.27% during the reporting period, while emerging markets equities, as measured by the MSCI Emerging Markets Index (net),⁴ gained 23.75%.

¹  Based on the Commerce Department's initial estimate announced on July 28, 2017, after the reporting period had ended.

²  The S&P 500 Index is an unmanaged, weighted index composed of 500 widely held common stocks varying in composition and is not available for direct investment. Investors should note that indices do not reflect the deduction of fees and expenses.

³  The MSCI EAFE Index (net) is an index of stocks designed to measure the investment returns of developed economies outside of North America. Net total return indices reinvest dividends after the deduction of withholding taxes, using a tax rate applicable to non-resident institutional investors who do not benefit from double taxation treaties. The index is constructed and managed with a view to being fully investable from the perspective of international institutional investors. Investors should note that indices do not reflect the deduction of fees and expenses.

⁴  The MSCI Emerging Markets Index (net) is a market capitalization-weighted index composed of different emerging market countries in Europe, Latin America, and the Pacific Basin. Net total return indices reinvest dividends after the deduction of withholding taxes, using a tax rate applicable to non-resident institutional investors who do not benefit from double taxation treaties.

The fixed income market generated mixed results

The global fixed income market posted mixed results during the reporting period. In the US, Treasury yields moved sharply higher after the November elections as investors anticipated an uptick in growth and inflation. Additionally, Fed rate hikes pressured the shorter end of the yield curve. However, after peaking in mid-March 2017, yields moved lower amid skepticism about the Trump administration's growth initiatives. For the fiscal year as a whole, the yield on the US 10-year Treasury rose from 1.49% to 2.31% (bond yields and prices move in the opposite direction). The overall US bond market, as measured by the Bloomberg Barclays US Aggregate Index,⁵ returned -0.31% for the 12 months ended June 30, 2017. Returns of riskier fixed income securities were greater. High yield bonds, as measured by the BofA Merrill Lynch US High Yield Cash Pay Constrained Index⁶ gained 12.74% during the reporting period. Elsewhere, emerging markets debt, as measured by the J.P. Morgan Emerging Markets Bond Index Global (EMBI Global),⁷ rose 5.52%.

⁵  The Bloomberg Barclays US Aggregate Index is an unmanaged broad based index designed to measure the US dollar-denominated, investment-grade, taxable bond market. The index includes bonds from the Treasury, government-related, corporate, mortgage-backed, asset-backed and commercial mortgage-backed sectors. Investors should note that indices do not reflect the deduction of fees and expenses.

⁶  The BofA Merrill Lynch US High Yield Cash Pay Constrained Index is an unmanaged index of publicly placed, non-convertible, coupon-bearing US dollar denominated, below investment grade corporate debt with a term to maturity of at least one year. The index is market capitalization weighted, so that larger bond issuers have a greater effect on the index's return. However, the representation of any single bond issuer is restricted to a maximum of 2% of the total index. Investors should note that indices do not reflect the deduction of fees and expenses.

⁷  The J.P. Morgan Emerging Markets Bond Index Global (EMBI Global) is an unmanaged index which is designed to track total returns for US dollar denominated debt instruments issued by emerging market sovereign and quasi-sovereign entities: Brady bonds, loans and Eurobonds. Investors should note that indices do not reflect the deduction of fees and expenses.

Portfolio performance

For the 12 months ended June 30, 2017, Class A shares of UBS Dynamic Alpha Fund (the "Fund") returned 5.84% (Class A shares returned 0.00% after the deduction of the maximum sales charge), while Class P shares returned 6.05%. For purposes of comparison, the BofA Merrill Lynch US Treasury 1-5 Year Index returned -0.53% during the same time period, the MSCI World Index (net) returned 18.20%, and the Citigroup One-Month US Treasury Bill Index returned 0.42%. (Class P shares have lower expenses than other share classes of the Fund.)

Returns for all share classes over various time periods are shown on page 7; please note that these returns do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares, while the Index returns do not reflect the deduction of fees and expenses.)

The Fund produced a positive absolute return during the reporting period, driven by both market and currency allocation decisions.

During the reporting period, we used derivatives for risk management purposes and as a tool to help enhance returns across various strategies. With respect to our active currency strategy, utilizing currency forwards had a direct positive impact on Fund performance.¹ We used a variety of equity and fixed income futures and swaps to implement our market allocation strategy. Derivatives were just one tool, among others, that we used to implement our market allocation strategy. These derivatives, in aggregate, added to performance during the reporting period.

Portfolio performance summary²

What worked:

•  Overall, the Fund's equity positioning was positive for returns.

  – The Fund's long exposure to global equities (US, developed ex-US and emerging markets) contributed to performance over the reporting period. A number of equity markets have reached their all-time highs amid improving economic data and resurgent investor confidence.

  – The Fund benefited from certain relative value trades, such as being long developed ex-US equities versus US equities and long eurozone banks versus European large-cap equities, as well as broad emerging markets versus US equities. Developed ex-US equities strengthened amid a reduction in geopolitical risks and further commitments to accommodative monetary policy.

•  Overall, the Fund's fixed income positions were positive for performance.

  – The Fund's preference for global corporate bonds and European high yield bonds added value.

  – The Fund benefited from certain relative value trades, such as long German bunds versus French government bonds, long US Treasury Inflation-Protected Securities ("TIPS") versus US Treasuries and long 10-year US treasuries versus German 10-year bunds.

¹  Active currency strategy refers to those positions explicitly implemented by the portfolio manager in an effort to generate alpha and does not include the currency contracts utilized by the Fund for hedging purposes.

²  For a detailed commentary on the market environment in general during the reporting period, see pages 3-4.

UBS Dynamic Alpha Fund

•  Overall, the portfolio's active currency strategy was beneficial for results.

  – The Fund's long positions in the euro relative to the US dollar, long Australian dollar relative to the New Zealand dollar, long Mexican peso relative to the US dollar and long euro versus the Swiss franc all contributed to performance.

  – The Fund's long position in the Indian rupee relative to the Korean won proved beneficial for performance. The rupee was more resilient during this volatile time period amid interventions by the Reserve Bank of India and strong macro fundamentals.

What didn't work:

•  Certain equity positions detracted from results.

  – A preference for emerging markets minimum volatility equities over broad emerging markets equities detracted from performance.

  – Our long Spanish versus Italian equities detracted from performance toward the end of 2016.

  – Long-forgotten value stocks performed strongly following the US election outcome, but have since reverted back to underperforming growth stocks and the capitalization-weighted index, as evidenced by the negative performance of our long Russell 1000 Value position versus the S&P 500.

•  Certain fixed income positions detracted from results.

  – The Fund's long exposure to Australian duration detracted from results as the economy fared better than expected given lower commodity prices. This resulted in fewer rate cuts than expected.

  – The Fund's performance was negatively impacted by certain relative value trades, such as long positions in US Treasuries versus Italian government bonds. US Treasury yields rose sharply in the last two months of the year amid greater inflation expectations and a revision in anticipated moves by the US Federal Reserve Board.

•  Certain currency trades performed poorly during the reporting period.

  – A detractor from performance was the Fund's long position in the Mexican peso relative to the Canadian dollar. Despite solid fundamentals, the peso struggled amid protectionist and trade concerns after the result of the US presidential election.

  – The Fund's long exposure to the Japanese yen relative to the euro did not fare well over the first six months of the year since it was introduced. The euro has appreciated following European elections and potential hikes hinted at by the European Central Bank.

Pursuant to the written agreement, the Advisor is entitled to be reimbursed for any fees it waives and expenses it reimburses to the extent such reimbursement can be made during the three years following the period during which such fee waivers and expense reimbursements were made, provided that the reimbursement of the Advisor by the Fund will not cause the Fund to exceed any applicable expense limit that is in place for the Fund. The fee waiver/expense reimbursement agreement may be terminated by the Fund's Board of Trustees at any time and also will terminate automatically upon the expiration or termination of the Fund's advisory contract with the Advisor. Upon termination of the fee waiver/expense reimbursement agreement, however, UBS AM (Americas)'s three year recoupment rights will survive.

¹  Security was purchased pursuant to Regulation S under the Securities Act of 1933, which exempts from registration securities offered and sold outside of the United States. Such a security cannot be sold in the United States without either an effective registration statement filed pursuant to the Securities Act of 1933, or pursuant to an exemption from registration.

²  Security exempt from registration pursuant to Rule 144A under the Securities Act of 1933. These securities are considered liquid, unless noted otherwise, and may be resold in transactions exempt from registration, normally to qualified institutional buyers.

³  Variable or floating rate security. The interest rate shown is the current rate at the period end and changes periodically.

⁴  Security, or portion thereof, was on loan at the period end.

⁵  Perpetual investment. Date shown reflects the next call date.

⁶  Amount represents less than 0.005%.

⁷  Illiquid investment at the period end.

⁸  Rate shown is the discount rate at the date of purchase unless otherwise noted.

⁹  If the Fund is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) receive from the seller of protection an amount equal to the notional amount of the swap and deliver the referenced obligation or underlying securities comprising the referenced obligation or (ii) receive a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced obligation.

¹⁰  Payments made or received are based on the notional amount.

¹¹  If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced obligation or (ii) pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced obligation.

¹²  Credit spreads, represented in absolute terms, utilized in determining the market value as of period end serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default or other credit event occurring for the credit derivative. The credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity's credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement. A credit spread identified as "Defaulted" indicates a credit event has occurred for the referenced entity. Credit spreads are unaudited.

UBS Global Allocation Fund

Portfolio performance

For the 12 months ended June 30, 2017, Class A shares of UBS Global Allocation Fund (the "Fund") increased 12.51% (Class A shares returned 6.31% after the deduction of the maximum sales charge), while Class P shares increased 12.85%. In contrast, the Fund's benchmark, the 60% MSCI All Country World Index (net)/40% Citigroup World Government Bond Index (Hedged in USD), returned 10.05% during the same time period. For comparison purposes, the MSCI All Country World Index (net) returned 18.78% and the Citigroup World Government Bond Index (Hedged in USD) returned -2.00%. (Class P shares have lower expenses than other share classes of the Fund. Returns for all share classes over various time periods are shown on page 25; please note that these returns do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares, while the Index returns do not reflect the deduction of fees and expenses.)

The Fund produced a positive absolute return during the reporting period and outperformed the benchmark. Positive performance was primarily due to our active market allocation strategy and security selection.

During the reporting period, we used derivatives for risk management purposes and as a tool to help enhance returns across various strategies. With respect to our active currency strategy, utilizing currency forwards had a direct, modestly negative impact on Fund performance.¹ We used a variety of equity and fixed income options, futures and swaps to implement our market allocation strategy. Derivatives were just one tool, among others, that we used to implement our market allocation strategy. These derivatives, in aggregate, added to performance during the reporting period.

Portfolio performance summary²

What worked:

•  Overall active equity positions added to performance.

  – The Fund's long exposure to global equities (US, developed ex-US and emerging markets) contributed to performance over the reporting period. A number of equity markets ended the reporting period at all-time highs amid improving economic data and resurgent investor confidence.

  – The Fund benefited from certain relative value trades, such as being long developed ex-US equities versus US equities and long emerging markets equities versus US equities.

•  Overall, the portfolio's fixed income positions were positive for performance.

  – The Fund's allocations to high yield bonds and emerging markets debt were additive for performance.

  – The Fund benefited from certain relative value trades, such as long German bunds versus French government bonds and our preference for global corporate bonds over sovereigns. Global yields rose and credit spreads compressed during the reporting period.

•  Certain active currency positions were positive for performance.

  – The Fund's allocation to the Mexican peso relative to the US dollar and long euro position relative to the Swiss franc contributed to performance.

¹  Active currency strategy refers to those positions explicitly implemented by the portfolio manager in an effort to generate alpha and does not include the currency contracts utilized by the Fund for hedging purposes.

²  For a detailed commentary on the market environment in general during the reporting period, see pages 3-4.

UBS Global Allocation Fund

  – During the reporting period, the Fund maintained an overweight to the Indian rupee relative to the Taiwanese dollar. This was beneficial for performance as the rupee was more resilient during this volatile time period amid interventions by the Reserve Bank of India and strong macro fundamentals.

•  Overall, the portfolio's bottom-up security selection was positive for results.

  – Positive security selection came from within US equities, non-US equities and emerging markets equities.

What didn't work:

•  Certain equity trades detracted from performance during the reporting period.

  – A preference for emerging markets minimum volatility equities over broad emerging markets equities detracted from performance.

  – Long-forgotten value stocks performed strongly following the US election outcome, but have since reverted back to underperforming growth stocks and the capitalization-weighted index, as evidenced by the negative performance of our long Russell 1000 Value position versus the S&P 500.

  – The Fund's relative value trade of long Spanish versus Italian equities detracted from performance. We expected the Spanish market to outperform on the back of relative political and economic momentum. We decided to close the position after Mariano Rajoy was re-elected Prime Minister of Spain and we saw further pricing of a negative Italian referendum in the market.

•  Certain fixed income allocations detracted from results.

  – The Fund's long exposure to Australian duration detracted from results as the economy fared better than expected given lower commodity prices. This resulted in fewer rate cuts than expected.

  – The Fund's performance was negatively impacted by certain relative value trades, such as long US Treasuries versus Italian government bonds.

•  Overall, the portfolio's active currency positions detracted from performance.

  – A detractor from performance was the Fund's short Canadian dollar position versus both the Mexican peso and the US dollar.

  – The Fund's long exposure to the Japanese yen relative to the euro has not fared well since its introduction in late February of 2017. The euro has appreciated following European elections and potential rate hikes hinted at by the European Central Bank.

The annualized gross and net expense ratios, respectively, for each class of shares as in the October 28, 2016 prospectuses were as follows: Class A—1.46% and 1.30%; Class C—2.25% and 2.05%; Class P—1.19% and 1.05%. Net expenses reflect fee waivers and/or expense reimbursements, if any, pursuant to an agreement that is in effect to cap the expenses. Effective October 28, 2016, the Trust, with respect to the Fund, and UBS Asset Management (Americas) Inc., the Fund's investment advisor ("UBS AM (Americas)" or the "Advisor"), have entered into a written agreement pursuant to which the Advisor has agreed to waive a portion of its management fees and/or to reimburse expenses (excluding expenses incurred through investment in other investment companies, interest, taxes, brokerage commissions, and extraordinary expenses to the extent necessary so that the Fund's ordinary operating expenses (excluding expenses incurred through investment in other investment companies, interest, taxes, brokerage commissions, and extraordinary expenses), through the period ending October 27, 2017, do not exceed 1.20% for Class A shares, 1.95% for Class C shares and 0.95% for Class P shares; Prior to October 28, 2016 UBS Global Allocation Fund's expense caps were 1.35%, 2.10% and 1.10% for Class A, C, and P shares, respectively. Pursuant to the written agreement, the Advisor is entitled to be reimbursed for any fees it waives and expenses it reimburses to the extent such reimbursement can be made during the three years following the period during which such fee waivers and expense reimbursements were made, provided that the reimbursement of the Advisor by the Fund will not cause the Fund to exceed any applicable expense limit that is in place for the Fund. The fee waiver/expense reimbursement agreement may be terminated by the Fund's Board of Trustees at any time and also will terminate automatically upon the expiration or termination of the Fund's advisory contract with the Advisor. Upon termination of the fee waiver/expense reimbursement agreement, however, UBS AM (Americas)'s three year recoupment rights will survive.

¹  Maximum sales charge for Class A shares is 5.5%. Class A shares bear ongoing 12b-1 service fees.

²  Maximum contingent deferred sales charge for Class C shares is 1% imposed on redemptions and is reduced to 0% after one year. Class C shares bear ongoing 12b-1 distribution and service fees.

³  Class P shares do not bear initial or contingent deferred sales charges or ongoing 12b-1 service and distribution fees, but Class P shares held through advisory programs may be subject to a program fee, which, if included, would have reduced performance.

⁴  The MSCI All Country World Index (net) is a free float-adjusted market capitalization weighted index that is designed to measure the equity market performance of developed and emerging markets. Net total return indices reinvest dividends after the deduction of withholding taxes, using a tax rate applicable to non-resident institutional investors who do not benefit from double taxation treaties. The index is constructed and managed with a view to being fully investable from the perspective of international institutional investors. Investors should note that indices do not reflect the deduction of fees and expenses.

⁵  The Citigroup World Government Bond Index (Hedged in USD) is an unmanaged market capitalization-weighted index designed to measure the performance of fixed-rate, local currency, investment-grade sovereign bonds with a one-year minimum maturity and is hedged back to the US dollar. Investors should note that indices do not reflect the deduction of fees and expenses.

⁶  The 60% MSCI All Country World Index (net)/40% Citigroup World Government Bond Index (Hedged in USD) is a unmanaged blended benchmark compiled by the Advisor. Investors should note that indices do not reflect the deduction of fees and expenses.

Prior to August 3, 2015, a 1% redemption fee was imposed on sales or exchanges of any class of shares of the Fund made during the specified holding period.

Past performance does not predict future performance, and the performance information provided does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. The return and principal value of an investment will fluctuate, so that an investor's shares, when redeemed, may be worth more or less than their original cost. Performance results assume reinvestment of all dividends and capital gain distributions at net asset value on the ex-dividend dates. Current performance may be higher or lower than the performance data quoted. For month-end performance figures, please visit www.ubs.com/us-mutualfundperformance.

Portfolio footnotes

*  Non-income producing security.

¹  Security exempt from registration pursuant to Rule 144A under the Securities Act of 1933. These securities are considered liquid, unless noted otherwise, and may be resold in transactions exempt from registration, normally to qualified institutional buyers.

²  Security, or portion thereof, was on loan at the period end.

³  Security was purchased pursuant to Regulation S under the Securities Act of 1933, which exempts from registration securities offered and sold outside of the United States. Such a security cannot be sold in the United States without either an effective registration statement filed pursuant to the Securities Act of 1933, or pursuant to an exemption from registration.

⁴  Debt security whose principal and/or interest payments are adjusted for inflation, unlike debt securities that make fixed principal and interest payments. The interest rate paid by the securities is fixed, while the principal value rises or falls based on changes in an index. Thus, if inflation occurs, the principal and interest payments on the securities are adjusted accordingly to protect investors from inflationary loss. During a deflationary period, the principal and interest payments decrease, although the securities' principal amounts will not drop below their face amounts at maturity. In exchange for the inflation protection, the securities generally pay lower interest rates than typical government securities from the issuer's country. Only if inflation occurs will securities offer a higher real yield than a conventional security of the same maturity.

⁶  If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced obligation or (ii) pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced obligation.

⁷  Payments made or received are based on the notional amount.

⁸  Credit spreads, represented in absolute terms, utilized in determining the market value as of period end serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default or other credit event occurring for the credit derivative. The credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity's credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement. A credit spread identified as "Defaulted" indicates a credit event has occurred for the referenced entity. Credit spreads are unaudited.

UBS International Sustainable Equity Fund

Portfolio performance

For the 12 months ended June 30, 2017, Class A shares of UBS International Sustainable Equity Fund (the "Fund") returned 21.43% (Class A shares returned 14.73% after the deduction of the maximum sales charge), while Class P shares returned 21.68%. The Fund's benchmark, the MSCI World ex USA Index (net) (the "Index"), returned 19.49%. (Class P shares have lower expenses than other share classes in the series. Returns for all share classes over various time periods are shown on page 38; please note that these returns do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares, while the Index returns do not reflect the deduction of fees and expenses.)

The Fund posted a positive absolute return and outperformed its benchmark during the reporting period, due to a balanced combination of stock selection and sector allocation.

Portfolio performance summary¹

What worked:

•  Stock selection in the industrials, materials and financials sectors contributed the most to performance.

•  Norsk Hydro is an aluminium manufacturer and renewable energy producer. The company benefited from higher growth expectations, as well as expectations of increased US infrastructure investments following Donald Trump's election. We closed our position in February 2017.

•  Nordea Bank is a universal pan-Nordic bank with a diversified business model allowing for a low volatility in earnings. The management team increased the company's dividend distribution rate and currently offers a 12% return on equity, which is expected to improve due to additional cost cutting. A higher-than-expected capital ratio for the third quarter of 2016 improved investors' confidence in the company's dividend policy.

•  Ping An Insurance is a China-based insurer and also a provider of financial services such as wealth management and credit card services. The company is increasing its footprint in Asia, reaching 131 million customers (up 20% in comparison with 2015). The profit per customer increased by 8% as overall revenues grew 11% in 2016.

•  From a sector allocation perspective, an average overweight to the information technology and average underweight to the consumer staples sectors contributed to performance.

What didn't work:

•  Stock selection in the energy and telecommunication services sectors detracted from performance during the reporting period.

•  Santos Limited is a gas producer with operations in Australia, Papua New Guinea, Malaysia, Indonesia and Vietnam. Highly leveraged, the company suffered from the recent low oil price environment, but delivered on cost cutting and divestment in 2016. We continue to find the company attractive as it shows strong efforts to manage its environmental impact and performs well on safety metrics.

•  KDDI Corp. provides a full range of telecommunication services in Japan, from fixed line to cellular. The company presented mixed results during the reporting period, as the number of subscribers declined. We continue to hold the company as, despite lower revenue due to pressure for lower tariff plans, we expect lower operating expenditures to lead to higher margins. We also expect a continued increase in its dividend pay-out.

•  Capita provides technology and back-office support solutions for businesses and public services. The UK-based company suffered from the "Brexit" vote and expectations of further cuts in public spending. We met with the new Chairman in October 2016 to understand the Board's view on its current challenges and its strategic position, which reaffirmed our positive longer-term outlook for the company.

•  Sector allocations to health care (average overweight) and consumer discretionary (average underweight) were modest detractors to performance.

Portfolio highlights

•  EasyJet is one of the largest and most successful low cost carriers in Europe. It has been taking market share and growing passenger count by 6% annually over the last four years, while also increasing margins and return on equity ("ROE"). Given the advantaged cost position of EasyJet, the fact that it currently has only a 9% share of the intra-European market, and that low cost carriers have about 30% of the market (up from 10% ten years ago), there is still plenty of share to win from the remainder of the market. EasyJet advantages include lower fleet costs due to superior asset utilization and efficiency, a strong brand that allows agility in fleet deployment and a very strong presence in primary airports. The company reports continued reductions in carbon emissions per passenger kilometer travelled due to efficiency improvements and ranks well in comparison with its peers. The company has also improved its relationship with its employees and customer engagement, as reflected by internal and third-party surveys.

•  Koninklijke DSM is a specialty chemicals company involved in health, nutrition and materials. In 2016, it launched a portfolio restructuring which should result in a higher valuation as the company becomes more focused and transparent. As a result, their business mix has improved by moving out of their pharmaceutical and commodity chemicals businesses, which were lower return and slower growth units. Koninklijke DSM's valuation is attractive, given: (a) the company has now exited its low return commodities business and; (b) for the majority of the past several years, returns in the company's largest business, nutrition, were declining, but now look likely to expand, due to a combination of internal restructuring under a new Chief Financial Officer, and rising vitamin prices. Uplift from higher vitamin prices should become apparent appearing first in animal then in human nutrition. Koninklijke DSM products play a role in improving nutrition and also reducing pollution in materials. The group targets 40-45% greenhouse gas efficiency improvements and to source half of its energy from renewable energy sources by 2025.

•  During the reporting period, we initiated several new positions, notably in Bank Central Asia, Sino Biopharmaceutical and Credit Agricole. We sold the Fund's positions in Astellas and Merck in the health care sector and NXP Semiconductor and ARM Holdings in the information technology sector.

The annualized gross and net expense ratios, respectively, for each class of shares as in the October 28, 2016 prospectuses were as follows: Class A—2.37% and 1.25%; Class C—3.15% and 2.00%; Class P—2.12% and 1.00%. Net expenses reflect fee waivers and/or expense reimbursements, if any, pursuant to an agreement that is in effect to cap the expenses. UBS Asset Management (Americas) Inc., the Fund's investment advisor ("UBS AM (Americas)" or the "Advisor"), has agreed irrevocably to waive its fees and reimburse certain expenses (excluding expenses incurred through investment in other investment companies, interest, taxes, brokerage commissions and extraordinary expenses) so that the Fund's ordinary operating expenses (excluding expenses incurred through investment in other investment companies, interest, taxes, brokerage commissions and extraordinary expenses) do not exceed 1.25% for Class A shares, 2.00% for Class C shares and 1.00% for Class P shares. This fee waiver and expense arrangement may only be amended or terminated by shareholders.

¹  Maximum sales charge for Class A shares is 5.5%. Class A shares bear ongoing 12b-1 service fees.

²  Maximum contingent deferred sales charge for Class C shares is 1% imposed on redemptions and is reduced to 0% after one year. Class C shares bear ongoing 12b-1 distribution and service fees.

³  Class P shares do not bear initial or contingent deferred sales charges or ongoing 12b-1 service and distribution fees, but Class P shares held through advisory programs may be subject to a program fee, which, if included, would have reduced performance.

⁴  The MSCI World ex USA Index (net) is a free float-adjusted market capitalization weighted index that is designed to measure the equity market performance of developed markets excluding the United States. Net total return indices reinvest dividends after the deduction of withholding taxes, using a tax rate applicable to non-resident institutional investors who do not benefit from double taxation treaties. The index is constructed and managed with a view to being fully investable from the perspective of international institutional investors. Investors should note that indices do not reflect the deduction of fees and expenses.

Prior to August 3, 2015, a 1% redemption fee was imposed on sales or exchanges of any class of shares of the Fund made during the specified holding period.

Past performance does not predict future performance, and the performance information provided does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. The return and principal value of an investment will fluctuate, so that an investor's shares, when redeemed, may be worth more or less than their original cost. Performance results assume reinvestment of all dividends and capital gain distributions at net asset value on the ex-dividend dates. Current performance may be higher or lower than the performance data quoted. For month-end performance figures, please visit www.ubs.com/us-mutualfundperformance.

UBS U.S. Large Cap Equity Fund

Portfolio performance

For the 12 months ended June 30, 2017, Class A shares of UBS U.S. Large Cap Equity Fund (the "Fund") returned 23.61% (Class A shares returned 16.82% after the deduction of the maximum sales charge), while Class P shares returned 23.87%. The Fund's benchmark, the Russell 1000 Index (the "Index"), returned 18.03% over the same time period. (Class P shares have lower expenses than other share classes of the Fund. Returns for all share classes over various time periods are shown on page 47; please note that the Fund's returns do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares, while the Index returns do not reflect the deduction of fees and expenses.)

The Fund outperformed the Index primarily due to stock selection.

Portfolio performance summary¹

What worked:

•  Stock selection within information technology was a top contributor to performance during the 12 months ended June 30, 2017. The Fund benefited from exposure to semiconductors and to communications and electronic equipment.

  – Micron Technology's outperformance was driven by its strong quarterly results and forward-looking guidance relative to market expectations. This has resulted from a continuingly balanced supply/demand environment in Flash memory, a type of computer hardware.

  – Western Digital also benefited from the supply/demand dynamics in Flash memory, as well as from speculation that the company might participate in, or profit from, the pending sale of Toshiba's Flash memory business.

  – Take-Two Interactive Software outperformed based on the overall strength of the videogame industry. We believe that videogame companies can grow faster than other areas of the entertainment industry due to more profitable digital downloads; increased genres, studios and platforms (including virtual reality, mobile and streaming); new engagement models (subscriptions, competitive gaming/"e-sports"); geographic growth (particularly in Asia and South America); multiplayer networked gaming; and the emergence of "e-sports" leagues.

•  Certain health care stocks made a positive contribution to relative returns. Within health care, we remain overweight to biotechnology and health care providers, and underweight medical equipment.

  –Shares of Bio-Rad traded higher during the 12 months as the market was pricing in the company's potential for increased margins in the attractive diagnostics area of healthcare, as well as future benefits from the rollout of its enterprise resource planning (ERP) system. (For details, see "Portfolio highlights.")

•  The Fund benefited from other successful stock selection decisions across sectors.

  – Caterpillar was one of the top contributors to Fund performance over the reporting period. The company benefited from increased margins, accelerating growth in resource industries and high business confidence. Growing Chinese infrastructure investments have been an additional tailwind that, combined with higher sales and operating leverage, resulted in increased revenue guidance for the full year. We sold out of the position after the stock price reached our estimate of intrinsic value.

¹  For a detailed commentary on the market environment in general during the reporting period, see page 3-4.

UBS U.S. Large Cap Equity Fund

What didn't work:

•  Stock selection in the consumer staples sector detracted from Fund returns.

  – Kroger was one of the Fund's main underperforming positions during the 12-month period. Kroger's performance has been hampered by 18 months of food deflation, which makes it difficult to grow top-line sales and leverage the high fixed cost of running the business. We believe Kroger is a well-managed company at the forefront of using customer analytics to drive loyalty in a highly fragmented and low margin industry. Unfortunately, the planned purchase of Whole Foods by Amazon presents a threat to Kroger's market share. This violated our research thesis for owning the stock, so we sold out of the position.

•  Several energy stocks made a negative contribution to performance. Energy continued to underperform based on concerns about excess supply and OPEC's ability to maintain discipline in the current low-price environment.

  –We have repositioned the Fund to reduce exposure to the sector. Within energy, however, we are focused on exploration and production (E&P) companies with good acreage and less exposure to changing oil prices. Gulfport Energy underperformed for the 12 months, and we sold out of the stock.

  – Oasis Petroleum is one of the company-specific opportunities we are pursuing in the Fund, while cautiously observing macroeconomic events. We continue to believe that global inventory trends will improve.

•  Stock selection within the financial sector detracted from relative returns.

  – Simon Property Group is a self-administered and self-managed real estate investment trust (REIT). The company owns, develops and manages retail real estate properties. Simon's stock price suffered from recent elevated fears about the future of "brick and mortar" retail. As the owner of some of the country's most productive regional malls, we believe Simon is strongly positioned to generate solid, high single-digit cash flow growth for the foreseeable future.

  – Synchrony Financial lost 15.9% from its share price in a single day after missing earnings expectations. We believe that the sharp fall in price was an overreaction by the market, so we used this opportunity to add to our position. We have confidence in the company's ability to grow its loan book more rapidly than other card issuers, while simultaneously returning its industry-leading excess capital position to its shareholders over the next few years. (For details, see "Portfolio highlights.")

Portfolio highlights

•  American Express is a global provider of credit card services. We believe the company will maintain its 20% return on equity (ROE) over the medium term, despite the increased competition in its core credit card issuance business. While increased competition could lead to weaker margins on discount revenues, we believe the strong secular global trend toward card usage and electronic transactions, and away from cash and check payment methods, will lead to solid top-line growth in coming years. In turn, we believe this should lead to stronger operating margins than is implied in current consensus estimates.

•  Bio-Rad is a manufacturer and distributor of life science research and clinical diagnostics products. The company is under-earning as management invests in the rollout of its enterprise resource planning (ERP) system to streamline key areas of the business. We believe margins should increase significantly, driving earnings per share estimates well ahead of consensus. We also like the hidden value in Bio-Rad's ownership stake in Sartorius, a biotechnology filtration company.

45

UBS U.S. Large Cap Equity Fund

•  Newell Brands is a marketer of consumer and commercial products. We believe the company's investments in capabilities across consumer insights, innovation and go-to-market, as well as a substantial step-up in brand spending, will positively impact top-line growth. This should lead to profitable share gains, higher margins and higher return on invested capital (ROIC). We believe the company's leading market share in several categories makes it well-placed to succeed across a highly fragmented competitor base. Additionally, we see opportunity for margin expansion from merger synergies.

•  Mondelez International manufactures and markets snack food and beverage products worldwide. The company's cookies and chocolate products are experiencing strong category growth in developing markets. We believe Mondelez is well-positioned to benefit from its geographic exposure and strong operations in the BRICS countries (Brazil, Russia, India, China and South Africa), as well as in next-wave markets, such as Indonesia and the Middle East. In addition, we see potential for restructuring in the company's developed markets business, which represents an attractive opportunity to improve profit margins.

•  Synchrony Financial is the largest private label supplier of credit cards in the US. We believe the company's excess capital position offers it a competitive advantage and the opportunity to return cash to shareholders. We also believe Synchrony should be able to generate high single-digit loan growth. The company continues to experience high retention rates among its private label customers. Additionally, we believe that given the company's strong capital position, it is well-equipped to weather any short-term uptick in charge offs driven by a weakening economy.

UBS U.S. Large Cap Equity Fund

Average annual total returns for periods ended 06/30/17 (unaudited)

	1 year			5 years			10 years
Before deducting maximum sales charge
Class A1		23.61	%		15.30	%		5.71	%
Class C2		22.63			14.44			4.92
Class P3		23.87			15.58			5.98
After deducting maximum sales charge

Class C2		21.63			14.44			4.92
Russell 1000 Index4		18.03			14.67			7.29

The annualized gross and net expense ratios, respectively, for each class of shares as in the October 28, 2016 prospectuses, supplemented from time to time, were as follows: Class A—1.93% and 0.95%; Class C—2.68% and 1.70%; Class P—1.64% and 0.70%. Net expenses reflect fee waivers and/or expense reimbursements, if any, pursuant to an agreement that is in effect to cap the expenses. Effective March 23, 2016, the Trust, with respect to the Fund, and UBS Asset Management (Americas) Inc., the Fund's investment advisor ("UBS AM (Americas)" or the "Advisor"), have entered into a written agreement pursuant to which the Advisor has agreed to waive a portion of its management fees and/or to reimburse expenses (excluding expenses incurred through investment in other investment companies, interest, taxes, brokerage commissions and extraordinary expenses) to the extent necessary so that the Fund's ordinary operating expenses (excluding expenses incurred through investment in other investment companies, interest, taxes, brokerage commissions and extraordinary expenses), through the period ending October 27, 2017, do not exceed 0.95% for Class A shares, 1.70% for Class C shares and 0.70% for Class P shares. Pursuant to the written agreement, the Advisor is entitled to be reimbursed for any fees it waives and expenses it reimburses to the extent such reimbursement can be made during the three years following the period during which such fee waivers and expense reimbursements were made, provided that the reimbursement of the Advisor by the Fund will not cause the Fund to exceed any applicable expense limit that is in place for the Fund. The fee waiver/expense reimbursement agreement may be terminated by the Fund's Board of Trustees at any time and also will terminate automatically upon the expiration or termination of the Fund's advisory contract with the Advisor. Upon termination of the fee waiver/expense reimbursement agreement, however, UBS AM (Americas)'s three year recoupment rights will survive.

¹  Maximum sales charge for Class A shares is 5.5%. Class A shares bear ongoing 12b-1 service fees.

²  Maximum contingent deferred sales charge for Class C shares is 1% imposed on redemptions and is reduced to 0% after one year. Class C shares bear ongoing 12b-1 distribution and service fees.

³  Class P shares do not bear initial or contingent deferred sales charges or ongoing 12b-1 service and distribution fees, but Class P shares held through advisory programs may be subject to a program fee, which, if included, would have reduced performance.

⁴  The Russell 1000 Index is designed to measure the performance of the large-cap segment of the US equity universe. It is a subset of the Russell 3000 Index and includes approximately 1,000 of the largest securities based on a combination of their market cap and current index membership. The Russell 1000 Index is constructed to provide a comprehensive and unbiased barometer for the large-cap segment and is completely reconstituted annually to ensure new and growing equities are reflected. Investors should note that indices do not reflect the deduction of fees and expenses.

Prior to August 3, 2015, a 1% redemption fee was imposed on sales or exchanges of any class of shares of the Fund made during the specified holding period.

Past performance does not predict future performance, and the performance information provided does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. The return and principal value of an investment will fluctuate, so that an investor's shares, when redeemed, may be worth more or less than their original cost. Performance results assume reinvestment of all dividends and capital gain distributions at net asset value on the ex-dividend dates. Current performance may be higher or lower than the performance data quoted. For month-end performance figures, please visit www.ubs.com/us-mutualfundperformance.

UBS U.S. Small Cap Growth Fund

Portfolio performance

For the 12 months ended June 30, 2017, Class A shares of UBS U.S. Small Cap Growth Fund (the "Fund") returned 23.75% (Class A shares returned 16.97% after the deduction of the maximum sales charge), while Class P shares returned 24.09%. The Fund's benchmark, the Russell 2000 Growth Index (the "Index"), returned 24.40% over the same time period. (Class P shares have lower expenses than other share classes of the Fund. Returns for all share classes over various time periods are shown on page 55; please note that the Fund's returns do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares, while the Index returns do not reflect the deduction of fees and expenses.)

The Fund underperformed the Index primarily due to sector and industry allocation decisions.

Portfolio performance summary¹

What worked:

•  Stock selection within the healthcare sector, as well as the Fund's overweight allocation to banks, contributed positively to performance during the 12 months ended June 30, 2017.

  – Exact Sciences, a company focused on commercializing a non-invasive molecular screening test for the early detection and prevention of colorectal cancer, outperformed for the 12-month period. The company reported first quarter 2017 test volumes and revenues that exceeded consensus estimates and provided a significant increase in annual guidance for both metrics. The stock also rose in response to UnitedHealthcare's decision to cover Exact Sciences' Cologuard fecal DNA test on an interval of once every three years for individuals aged 50-75 years. (For details, see "Portfolio highlights.")

  – Shares of Loxo Oncology, a cancer drug development and research company, traded higher, particularly after the company reported positive trial results in TRK-fusion cancer patients at the annual meeting of the American Society of Clinical Oncology in early June 2017.

  – ZELTIQ Aesthetics offers non-invasive, FDA-cleared procedures for eliminating body fat. ZELTIQ was acquired by Allergan during the reporting period, and the Fund subsequently sold its shares.

•  Several information technology names were positive for performance during the period.

  – Wix.com, a web-platform operator and developer, posted strong gains based on accelerating fundamentals. The stock price increased more than 50% during the first half of 2017. (For details, see "Portfolio highlights.")

  – Universal Display Corporation is a manufacturer of emitters and materials supporting organic light-emitting diodes display technology. The stock outperformed after reporting first quarter 2017 results that beat consensus expectations. In addition, Universal Display's management raised its guidance for 2017 driven by increasing AMOLED display capacity plans and continued momentum ahead of the iPhone 8 launch. (For details, see "Portfolio highlights.")

What didn't work:

•  The Fund's allocation to the energy sector, as well as certain information technology stocks, contributed negatively to performance.

  – Synchronoss Technologies is a provider of e-commerce transaction management solutions to the communications services market. Shares fell after the company preannounced disappointing first quarter 2017 results, as well as the departure of the recently appointed Chief Executive Officer and Chief Financial Officer. We closed our position in the company prior to the end of the reporting period.

¹  For a detailed commentary on the market environment in general during the reporting period, see pages 3-4.

53

UBS U.S. Small Cap Growth Fund

  – 8x8 Inc. provides internet protocol voice, video and data communications technologies to small and midsized businesses. Shares underperformed on concerns about increased competition. We continue to believe 8x8 is well-positioned, and remain overweight. (For details, see "Portfolio highlights.")

•  A handful of other stock selection decisions detracted from the Fund's performance during the 12 months ended June 30, 2017.

  – The Finish Line, a retailer of athletic apparel and footwear, saw its shares decline during the first half of 2017 after the company reported disappointing sales and earnings.

  – The stock price of IMAX, an end-to-end cinematic solution containing proprietary software, theater architecture and equipment, declined in response to weak box office sales.

  – Envision Healthcare provides health care services, including physician-led and ambulatory surgery center management and transportation. Shares fell on softer-than-expected fourth quarter 2016 results and initial 2017 guidance.

Portfolio highlights

•  Exact Sciences is a molecular diagnostics company focusing on the early detection and prevention of colorectal cancer. The company has exclusive intellectual property protecting its non-invasive, molecular screening technology for the detection of colorectal cancer, Cologuard. We believe Exact Sciences is in the midst of a positive inflection with Cologuard uptake increasing.

•  Wix.com is a web platform that offers solutions for developing customized websites and applications. The company is experiencing rapid growth, driven by the continued move online by small and medium-sized businesses (SMBs). Websites are crucial for all businesses today, and Wix.com provides SMBs with an easy-to-use web design solution that also incorporates e-commerce capabilities.

•  Universal Display Corporation is a leader in the research, development and commercialization of organic light-emitting diode technologies and materials. We remain positive regarding the company's expected industry shipments and the overall increase in OLED manufacturing in 2017.

•  Ollie's Bargain Outlet operates a chain of retail stores, primarily in the eastern U.S., that offer brand name products at discounted and closeout prices. Ollie's seeks to deliver sustainable earnings growth in the high teens by growing its square footage by 15% or more annually and driving flat to slightly positive same store sales growth. As the company continues to grow its scale, it is able to procure a greater selection and volume of closeouts from a variety of manufacturers and retail stores.

•  8x8 Inc. is one of the leading providers of unified communications as a service. The company's cloud-based solutions enable communications and collaboration on a platform that includes voice, video, contact center and desktop. 8x8's solutions allow enterprises to easily deploy and scale their communications platforms without large upfront expenses.

The Trust, with respect to the Fund, and UBS Asset Management (Americas) Inc. the Fund's investment advisor ("UBS AM (Americas)" or the "Advisor"), have entered into a written agreement pursuant to which the Advisor has agreed to waive a portion of its management fees and/or to reimburse expenses (excluding expenses incurred through investment in other investment companies, interest, taxes, brokerage commissions, extraordinary expenses, and dividend expense and security loan fees for securities sold short) to the extent necessary so that the Fund's ordinary operating expenses (excluding expenses incurred through investment in other investment companies, interest, taxes, brokerage commissions, extraordinary expenses, and dividend expense and security loan fees for securities sold short), through the period ending October 27, 2017, do not exceed 1.24% for Class A shares, 1.99% for Class C shares and 0.99% for Class P shares. Pursuant to the written agreement, the Advisor is entitled to be reimbursed for any fees it waives and expenses it reimburses to the extent such reimbursement can be made during the three years following the period during which such fee waivers and expense reimbursements were made, provided that the reimbursement of the Advisor by the Fund will not cause the Fund to exceed any applicable expense limit that is in place for the Fund. The fee waiver/expense reimbursement agreement may be terminated by the Fund's Board of Trustees at any time and also will terminate automatically upon the expiration or termination of the Fund's advisory contract with the Advisor. Upon termination of the fee waiver/expense reimbursement agreement, however, UBS AM (Americas)'s three year recoupment rights will survive.

¹  Maximum sales charge for Class A shares is 5.5%. Class A shares bear ongoing 12b-1 service fees.

²  Maximum contingent deferred sales charge for Class C shares is 1% imposed on redemptions and is reduced to 0% after one year. Class C shares bear ongoing 12b-1 distribution and service fees.

³  Class P shares do not bear initial or contingent deferred sales charges or ongoing 12b-1 service and distribution fees, but Class P shares held through advisory programs may be subject to a program fee, which, if included, would have reduced performance.

⁴  The Russell 2000 Growth Index measures the performance of the small-cap growth segment of the US equity universe. It includes those Russell 2000 Index companies with higher price-to-book ratios and higher forecasted growth values. The Russell 2000 Growth Index is constructed to provide a comprehensive and unbiased barometer for the small-cap growth segment. The Index is completely reconstituted annually to ensure larger stocks do not distort the performance and characteristics of the true small-cap opportunity set and that the represented companies continue to reflect growth characteristics. Investors should note that indices do not reflect the deduction of fees and expenses.

Prior to August 3, 2015, a 1% redemption fee was imposed on sales or exchanges of any class of shares of the Fund made during the specified holding period.

The Fund invests in IPOs which may have a magnified impact on performance.

Past performance does not predict future performance, and the performance information provided does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares.

UBS Total Return Bond Fund

Portfolio performance

For the 12 months ended June 30, 2017, Class P shares of the UBS Total Return Bond Fund (the "Fund") returned 1.32%. (Class P shares have lower expenses than other share classes of the Fund. Returns for all share classes over various time periods are shown on page 64.) For comparison purposes, the Bloomberg Barclays US Aggregate Bond Index (the "Index") returned -0.31%. (Please note that the Fund's returns do not reflect the deduction of taxes that a shareholder would pay on the redemption of Fund shares, while index returns do not reflect the deduction of fees and expenses.)

The fund posted a positive return during the reporting period and outperformed its benchmark. This was primarily due to security selection and sector exposure.

Market commentary¹

The 12 months ended June 30, 2017, were marked by a number of global political events, most notably the surprise election of Donald Trump as the 45th President of the United States. While President Trump's planned fiscal stimulus policies (e.g., infrastructure spending, health care reform, deregulation and tax reform) are largely expected to spur growth, his administration continues to have great difficulty bringing them to bear, primarily due to political gridlock.

For the reporting period, 2-year, 10-year, and 30-year U.S. Treasury yields rose 71 basis points (bps), 84 bps, and 66 bps, respectively, to close the reporting period at 1.38%, 2.30%, and 2.84%, respectively. The Federal Reserve Board (the "Fed") raised its policy rate 25 bps three times during the reporting period, citing improvement in the labor market, a continued decrease in the unemployment rate and an uptick in inflation. In addition to the rate hikes, the Fed announced at its June 2017 meeting a plan to begin gradually winding down its balance sheet.

Improved fundamentals and strong investor demand globally for higher yields caused nearly all fixed income sectors to outperform Treasuries over the reporting period, with the more rate-sensitive sectors underperforming the more credit-sensitive sectors. For example, the Bloomberg Barclays US Mortgage-Backed Securities Index returned -0.06% over the reporting period, compared to the Bloomberg Barclays US Corporate High Yield Index's gain of 2.28%.

Despite continued Fed rate hikes, the US dollar strengthened a mere 0.12% over the reporting period, as inflation data came in weaker than anticipated. Lastly, oil prices ended the reporting period 11% higher to close June at nearly $46 per barrel, as OPEC and other major oil exporters agreed to cut production (supply) in 2017.

Portfolio performance summary

What worked:

•  Security selection was additive for results. Security selection was the most meaningful contributor to performance over the reporting period, specifically within financials, industrials and commercial mortgage-backed securities ("CMBS"). Financials outperformed due to rising rates (i.e., higher profitability) and the hope for future deregulation. Industrials outperformed in step with the rally in equities, whereas CMBS outperformed due to solid fundamentals and strong investor demand.

•  Sector exposure was beneficial overall. The Fund was overweight various credit sectors over the reporting period, most notably corporates (both investment-grade and high yield) and CMBS. This positioning was based on our belief that fundamentals were solid and higher-yielding bonds would attract investors' demand for yield. This benefited performance, as credit-sensitive sectors meaningfully outperformed rate-sensitive sectors (e.g., Treasuries) over the reporting period.

¹  For a detailed commentary on the market environment in general during the reporting period, see pages 3-4.

62

UBS Total Return Bond Fund

What didn't work:

•  Agency residential mortgage-backed security ("RMBS") exposure detracted from performance. The Fund's tactical positioning to agency RMBS throughout the reporting period detracted from performance, particularly in the fourth quarter of 2016, when rates rose significantly and agency RMBS underperformed.

•  Emerging markets currency exposure was a headwind for performance. The Fund's tactical long exposure to the Mexican peso detracted from performance, particularly in the fourth quarter of 2016, when the peso depreciated due to the surprise election of Donald Trump as President.

Market outlook

2017 thus far has been characterized by a flatter yield curve and continued demand for yield. The market waits in anticipation for the Trump administration's pro-growth/inflationary fiscal policies to get under way, while US fixed income markets offer some of the highest developed market yields in the world. The right-wing populist movement sparked by Brexit and Trump seems to have lost momentum of late, as Republican control of the White House and both houses of Congress in the US thus far has fallen short of expectations, the Dutch Presidential election in March resulted in a loss for Geert Wilders (a far-right candidate) and the French Presidential election in May resulted in a loss for Marine Le Pen (also a far-right candidate). Focus now shifts to the UK, where British Prime Minister Theresa May fights to retain her seat following her party's disappointing showing in the June snap elections, and the German federal elections in September, where the incumbent, Angela Merkel, maintains a modest lead in the latest opinion polls. On the geopolitical front, tensions between Russia and the US over Syria seem to have percolated once again, while tensions between North Korea and the US continue to rise. Yet despite all of these uncertainties and pockets of volatility, investor confidence and demand for yield remain strong, putting downward pressure on yields and grinding spreads even tighter, while monetary policy for the time being remains quite accommodative. Given this backdrop, it is our view that interest rates are likely to trend higher over the medium-term due to gradually improving fundamentals and moderately increasing inflation. Meanwhile, carry remains attractive due to the continued demand for yield.²

²  Carry refers to an investment strategy that involves borrowing at a low interest rate and using the proceeds to invest in an asset that produces a higher rate of return than the initial borrowing cost.

The annualized gross and net expense ratios as in the October 28, 2016 prospectuses were as follows: Class A—1.21% and 0.75%; Class C—1.71% and 1.25%; Class P—1.21% and 0.50%. Net expenses reflect fee waivers and/or expense reimbursements, if any, pursuant to an agreement that is in effect to cap the expenses. The Trust, with respect to the Fund, and UBS Asset Management (Americas) Inc., the Fund's investment advisor ("UBS AM (Americas)" or the "Advisor"), have entered into a written agreement pursuant to which the Advisor has agreed to waive a portion of its management fees and/or to reimburse expenses (excluding expenses incurred through investment in other investment companies, interest, taxes, brokerage commissions and extraordinary expenses) to the extent necessary so that the Fund's ordinary operating expenses (excluding expenses incurred through investment in other investment companies, interest, taxes, brokerage commissions and extraordinary expenses), through the period ending October 27, 2017, do not exceed 0.75% for Class A shares, 1.25% for Class C shares and 0.50% for Class P shares. Pursuant to the written agreement, the Advisor is entitled to be reimbursed for any fees it waives and expenses it reimburses to the extent such reimbursement can be made during the three years following the period during which such fee waivers and expense reimbursements were made, provided that the reimbursement of the Advisor by the Fund will not cause the Fund to exceed any applicable expense limit that is in place for the Fund. The fee waiver/expense reimbursement agreement may be terminated by the Fund's Board of Trustees at any time and also will terminate automatically upon the expiration or termination of the Fund's advisory contract with the Advisor. Upon termination of the fee waiver/expense reimbursement agreement, however, UBS AM (Americas)'s three year recoupment rights will survive.

¹  Inception date of A and C shares of UBS Total Return Bond Fund and the index is September 29, 2016. 10 years fund performance is shown for Class P Shares, and the 10 years index performance of the Bloomberg Barclays US Aggregate Index is 4.48%. The Fund's Class P shares acquired the assets and liabilities of Fort Dearborn Income Securities, Inc., a closed-end fund (the "Predecessor Fund"), prior to the opening of business on May 23, 2016 (the "Reorganization"). The Predecessor Fund was also managed by the Advisor, and the day-to-day management of, and investment decisions for, the Fund and the Predecessor Fund are made by the same portfolio management team. The Funds have generally similar investment objectives and strategies. Therefore, the information shown above reflects the historical performance of the Predecessor Fund for periods prior to the Reorganization. The performance information shown for periods prior to the Reorganization is for the Predecessor Fund and may not be representative of performance of the Fund.

²  Maximum sales charge for Class A shares is 3.75%. Class A shares bear ongoing 12b-1 service fees.

³  Maximum contingent deferred sales charge for Class C shares is 0.75% imposed on redemptions and is reduced to 0% after one year. Class C shares bear ongoing 12b-1 distribution and service fees.

⁴  Class P shares do not bear initial or contingent deferred sales charges or ongoing 12b-1 service and distribution fees, but Class P shares held through advisory programs may be subject to a program fee, which, if included, would have reduced performance.

⁵  The Bloomberg Barclays US Aggregate Index is an unmanaged broad based index designed to measure the US dollar-denominated, investment-grade, taxable bond market. The index includes bonds from the Treasury, government-related, corporate, mortgage-backed, assetbacked and commercial mortgage-backed sectors. Investors should note that indices do not reflect the deduction of fees and expenses.

A temporary redemption fee of 2% was imposed on sales of Class P shares of the Fund between May 23, and August 22, 2016.

Past performance does not predict future performance, and the performance information provided does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. The return and principal value of an investment will fluctuate, so that an investor's shares, when redeemed, may be worth more or less than their original cost. Performance results assume reinvestment of all dividends and capital gain distributions at net asset value on the ex-dividend dates. Current performance may be higher or lower than the performance data quoted. For month-end performance figures, please visit www.ubs.com/us-mutualfundperformance.

At June 30, 2017, there were no transfers between Level 1 and Level 2. At June 30, 2016, $17,940,956 of short-term investments were classified within Level 2 and are now classified within Level 1 in accordance with the investment valuation leveling policy.

Portfolio footnotes

¹  Security exempt from registration pursuant to Rule 144A under the Securities Act of 1933. These securities are considered liquid, unless noted otherwise, and may be resold in transactions exempt from registration, normally to qualified institutional buyers.

²  Variable or floating rate security. The interest rate shown is the current rate at the period end and changes periodically.

³  Perpetual investment. Date shown reflects the next call date.

⁴  Security is being fair valued by a valuation committee under the direction of the board of trustees.

⁵  Security was purchased pursuant to Regulation S under the Securities Act of 1933, which exempts from registration securities offered and sold outside of the United States. Such a security cannot be sold in the United States without either an effective registration statement filed pursuant to the Securities Act of 1933, or pursuant to an exemption from registration.

⁶  Debt security whose principal and/or interest payments are adjusted for inflation, unlike debt securities that make fixed principal and interest payments. The interest rate paid by the securities is fixed, while the principal value rises or falls based on changes in an index. Thus, if inflation occurs, the principal and interest payments on the securities are adjusted accordingly to protect investors from inflationary loss. During a deflationary period, the principal and interest payments decrease, although the securities' principal amounts will not drop below their face amounts at maturity. In exchange for the inflation protection, the securities generally pay lower interest rates than typical government securities from the issuer's country. Only if inflation occurs will securities offer a higher real yield than a conventional security of the same maturity.

⁷  Illiquid investment at the period end.

⁸  Payments made or received are based on the notional amount.

⁹  Payment is based on the performance of the underlying Markit iBoxx USD Liquid High Yield Index.

UBS Municipal Bond Fund

Portfolio performance

For the 12 months ended June 30, 2017, Class A shares of UBS Municipal Bond Fund (the "Fund") declined 1.11% (Class A shares returned -3.32% after the deduction of the maximum sales charge), while Class P shares declined 0.97%. For comparison purposes, the Fund's benchmark, the Bloomberg Barclays Municipal Bond Index (the "Index"), declined 0.49%, and the Bloomberg Barclays Municipal Managed Money Intermediate (1–17) Index returned -0.64% over the same time period. (Class P shares have lower expenses than other share classes of the Fund. Returns for all share classes over various time periods are shown on page 78; please note that the Fund's returns do not reflect the deduction of taxes that a shareholder could pay on Fund distributions or the redemption of Fund shares, while the Index returns do not reflect the deduction of fees and expenses.)

The Fund posted a negative return during the reporting period and underperformed its benchmark. This was primarily due to an underweight to the one- to seven-year portion of the municipal yield curve and an overweight to AAA-rated municipal securities.

Portfolio performance summary¹

What worked

•  Duration positioning was a positive for performance. Having a shorter duration than that of the benchmark was rewarded as the overall municipal market generated negative results during the reporting period.

What didn't work:

•  Yield curve positioning detracted from results. In particular, an underweight to the short end of the municipal yield curve (1–7 year maturities) was a headwind for results as this portion of the curve outperformed the Index. (The yield curve plots the interest rates, at a set point in time, of bonds having equal credit quality, but differing maturity dates.)

•  An overweight to AAA-rated municipal bonds was not beneficial, as lower rated securities outperformed their higher quality counterparts during the reporting period.

•  Security selection of A-rated municipal securities detracted from results.

•  Positioning in certain sectors detracted from performance. In particular, underweights to the housing and industrial development revenue/pollution control revenue sectors were headwinds for results as they outperformed the Index.

Outlook

The municipal fixed income market has been in a strong technical position since the end of tax season. Year-to-date, aggregate net inflows into tax-exempt mutual funds have totaled about $5.3 billion, according to J.P. Morgan. Compared to the fourth quarter of 2016, which saw a mass exodus from tax-exempts, 2017 has seen a strong demand rebound amid a higher rate environment. We anticipate that this trend will continue through the summer, as July and August are heavy maturity and coupon-paying months.

Robust demand for securities inside of five years, coupled with lower supply, has pushed prices to more expensive levels than we have seen in a while. While rising rates tend to lead to underperformance in municipals, we believe this is unlikely. The supply/demand imbalances that we are seeing—the strong demand for shorter-term securities and the not-quite-as-strong demand for longer-term securities due to fears of a rate rise—should continue to support the municipal market.

¹  For a detailed commentary on the market environment in general during the reporting period, see pages 3-4.

UBS Municipal Bond Fund

From a credit perspective, generally, we continue to favor AA- and AAA-rated bonds at tighter spreads rather than reach for yield in the A and BBB categories, though A and BBB may become more attractive if spreads widen further. While we maintain no exposure to Puerto Rico, we are closely following events on the island to determine if there exists any lesson to be learned for potential future investments in the market. Credit contagion and ensuing credit spread widening are a real possibility.

The annualized gross and net expense ratios, respectively, for each class of shares as in the October 28, 2016 prospectuses were as follows: Class A—1.15% and 0.65%; Class C—1.65% and 1.15%; Class P—0.89% and 0.40%. Net expenses reflect fee waivers and/or expense reimbursements, if any, pursuant to an agreement that is in effect to cap the expenses. The Trust, with respect to the Fund, and UBS Asset Management (Americas) Inc., the Fund's investment advisor ("UBS AM (Americas)" or the "Advisor"), have entered into a written agreement pursuant to which the Advisor has agreed to waive a portion of its management fees and/or to reimburse expenses (excluding expenses incurred through investment in other investment companies, interest, taxes, brokerage commissions and extraordinary expenses) to the extent necessary so that the Fund's ordinary operating expenses (excluding expenses incurred through investment in other investment companies, interest, taxes, brokerage commissions and extraordinary expenses), through the period ending October 27, 2017, do not exceed 0.65% for Class A shares, 1.15% for Class C shares and 0.40% for Class P shares. Pursuant to the written agreement, the Advisor is entitled to be reimbursed for any fees it waives and expenses it reimburses to the extent such reimbursement can be made during the three years following the period during which such fee waivers and expense reimbursements were made, provided that the reimbursement of the Advisor by the Fund will not cause the Fund to exceed any applicable expense limit that is in place for the Fund. The fee waiver/expense reimbursement agreement may be terminated by the Fund's Board of Trustees at any time and also will terminate automatically upon the expiration or termination of the Fund's advisory contract with the Advisor. Upon termination of the fee waiver/expense reimbursement agreement, however, UBS AM (Americas)'s three year recoupment rights will survive.

¹  Inception date of all shares of UBS Municipal Bond Fund and the indices is November 10, 2014.

²  Maximum sales charge for Class A shares is 2.25%. Class A shares bear ongoing 12b-1 service fees.

³  Maximum contingent deferred sales charge for Class C shares is 0.75% imposed on redemptions and is reduced to 0% after one year. Class C shares bear ongoing 12b-1 distribution and service fees.

⁴  Class P shares do not bear initial or contingent deferred sales charges or ongoing 12b-1 service and distribution fees, but Class P shares held through advisory programs may be subject to a program fee, which, if included, would have reduced performance.

⁵  The Bloomberg Barclays Municipal Bond Index is an unmanaged index designed to measure the total return of the US dollar denominated tax exempt bond market. Investors should note that indices do not reflect the deduction of fees and expenses.

⁶  The Bloomberg Barclays Municipal Managed Money Intermediate (1-17) Index is an unmanaged sub-index of the Barclays Municipal Managed Money Index, which is a rules-based, market-value-weighted index designed to track the performance of municipal securities issued by state and local municipalities whose interest is exempt from federal income tax and the federal alternative minimum tax. Investors should note that indices do not reflect the deduction of fees and expenses.

Prior to August 3, 2015, a 1% redemption fee was imposed on sales or exchanges of any class of shares of the Fund made during the specified holding period.

Past performance does not predict future performance, and the performance information provided does not reflect the deduction of taxes that a shareholder could pay on Fund distributions or the redemption of Fund shares. The return and principal value of an investment will fluctuate, so that an investor's shares, when redeemed, may be worth more or less than their original cost. Performance results assume reinvestment of all dividends and capital gain distributions at net asset value on the ex-dividend dates. Current performance may be higher or lower than the performance data quoted. For month-end performance figures, please visit www.ubs.com/us-mutualfundperformance.

Explanation of expense disclosure

As a shareholder of the Funds, you incur two types of costs: (1) transactional costs (as applicable); including sales charges (loads); and (2) ongoing costs, including management fees; service and/or distribution (12b-1) fees (if applicable); and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in each Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example below is based on an investment of $1,000 invested at the beginning of the period and held for the entire period, January 1, 2017 to June 30, 2017.

Actual expenses

The first line for each class of shares in the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over a period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses paid during period" to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The second line for each class of shares in the table below provides information about hypothetical account values and hypothetical expenses based on that Fund's actual expense ratios for each class of shares and an assumed rate of return of 5% per year before expenses, which is not that Fund's actual return for each class of shares. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in a Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs (as applicable), such as sales charges (loads). Therefore, the second line in the table for each class of shares is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

This projection assumes that annualized expense ratios were in effect during the period January 1, 2017 to June 30, 2017.

Organization and significant accounting policies

The UBS Funds (the "Trust") is an open-end management investment company registered with the US Securities and Exchange Commission ("SEC") under the Investment Company Act of 1940 (the "1940 Act"), as amended, currently offering multiple series representing separate investment portfolios. The Trust is a Delaware statutory trust organized on August 13, 1993. The trustees of the Trust have authority to issue an unlimited number of shares of beneficial interest at par value of $0.001 per share.

The Trust has seven Funds available for investment, each having its own investment objectives and policies: UBS Dynamic Alpha Fund, UBS Global Allocation Fund, UBS International Sustainable Equity Fund, UBS U.S. Large Cap Equity Fund, UBS U.S. Small Cap Growth Fund, UBS Total Return Bond Fund and UBS Municipal Bond Fund, (each a "Fund", and collectively, the "Funds"). Each of the Funds is classified as a diversified investment company with the exception of UBS Dynamic Alpha Fund and UBS Municipal Bond Fund, which are classified as non-diversified for purposes of the 1940 Act.

UBS Asset Management (Americas) Inc. ("UBS AM" or the "Advisor") serves as the investment advisor and administrator for the Funds. UBS Asset Management (US) Inc. ("UBS AM (US)") serves as principal underwriter for the Funds. UBS AM and UBS AM (US) are indirect wholly owned subsidiaries of UBS Group AG. UBS Group AG is an internationally diversified organization with headquarters in Zurich, Switzerland. UBS Group AG operates in many areas of the financial services industry.

The Funds currently offer Class A, Class C and Class P shares. Each class represents interests in the same assets of the applicable Fund and the classes are identical except for differences in their sales charge structures, ongoing service and distribution charges and certain transfer agency and related services expenses. All classes of shares have equal voting privileges except that each class has exclusive voting rights with respect to its service and/or distribution plan, if any. Class P shares have no service or distribution plan.

The Class P shares of the UBS Total Return Bond Fund acquired the assets and liabilities of Fort Dearborn Income Securities, Inc., a closed-end management investment company organized as a Illinois corporation (the "Predecessor Fund"), prior to the opening of business on May 23, 2016 (the "Reorganization"). The UBS Total Return Bond Fund's investment advisor, UBS AM, was the advisor for the Predecessor Fund, and the day-to-day management of, and investment decisions for, the UBS Total Return Bond Fund and the Predecessor Fund are made by the same portfolio managers. The Funds have generally similar investment objectives and strategies. As such, the Predecessor Fund was designed as accounting survivor of the Reorganization. The UBS Total Return Bond Fund's Class P shares have adopted the historical performance of the Predecessor Fund. In connection with the Reorganization, the fiscal year end for UBS Total Return Bond Fund has changed from September 30th to June 30th. As such, the fiscal period ended June 30, 2016 for UBS Total Return Bond Fund reflects the nine month period from October 1, 2015 through June 30, 2016.

The Trust accounts separately for the assets, liabilities and operations of each Fund. Expenses directly attributable to each Fund are charged to that Fund's operations; expenses which are applicable to all Funds are allocated among them on a pro rata basis.

In the normal course of business, the Funds may enter into contracts that contain a variety of representations that provide indemnification for certain liabilities. The Funds' maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Funds that have not yet occurred. However, the Funds have not had any prior claims or losses pursuant to these contracts and expect the risk of loss to be remote.

Under certain circumstances, shareholders of the Funds may receive payment for redemptions in securities rather than in cash.

Notes to financial statements

The Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") is the exclusive reference of authoritative US generally accepted accounting principles ("US GAAP") recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the SEC under authority of federal laws are also sources of authoritative US GAAP for SEC registrants. The Funds' financial statements are prepared in accordance with US GAAP, which may require the use of management estimates and assumptions. Actual results could differ from those estimates.

In August 2014, the FASB issued Accounting Standard Update No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): "Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern" ("ASU 2014-15"). The update provides guidance about management's responsibility to evaluate whether there is substantial doubt about the entity's ability to continue as a going concern and to provide related footnote disclosure. Management has evaluated relevant conditions and events, which are known and reasonably knowable, and has determined that there are no conditions and events that raise substantial doubt about the Funds' ability to continue as a going concern.

In October 2016, the SEC adopted new rules and forms, and amendments to certain current rules and forms, to modernize reporting and disclosure of information by registered investment companies. The amendments to Regulation S-X will require standardized, enhanced disclosure about derivatives in investment company financial statements, and will also change the rules governing the form and content of such financial statements. The amendments to Regulation S-X take effect on August 1, 2017. At this time, management is assessing the anticipated impact of these regulatory developments.

The following is a summary of significant accounting policies:

Investment transactions, investment income and expenses: Investment transactions are recorded on the trade date. Realized gains and losses from investment transactions and foreign exchange transactions are calculated using the identified cost method. Dividend income and expense are recorded on the ex-dividend date ("ex-date") except in the case of certain dividends from foreign securities which are recorded as soon after the ex-date as the respective Fund, using reasonable diligence, becomes aware of such dividends. Interest income is recorded on an accrual basis. Discounts are accreted and premiums are amortized as adjustments to interest income and the identified cost of investments.

Income, expenses (excluding class-specific expenses) and realized/unrealized gains/losses are allocated proportionately to each class of shares based upon the relative net asset value of outstanding shares (or the value of dividend eligible shares, as appropriate) of each class at the beginning of the day after adjusting for current capital share activity of the respective classes. Class specific expenses are charged directly to the applicable class of shares.

Dividends and distributions: Dividends and distributions to shareholders are recorded on the ex-dividend date. The amount of dividends from net investment income and distributions from net realized capital gains and/or return of capital are determined in accordance with US federal income tax regulations, which may differ from US GAAP. These "book/tax" differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax-basis treatment; temporary differences do not require reclassification.

Foreign currency translation: The books and records of the Funds are maintained in US dollars. Foreign currency amounts are translated into US dollars as follows: (1) the foreign currency market value of investment securities and other assets and liabilities stated in foreign currencies are translated into US dollars based on the current exchange rates each business day; and (2) purchases and sales of investment securities and income and expenses are translated at the rate of exchange prevailing on the respective dates of such transactions. The resulting exchange gains and losses are included in the Statement of operations.

Notes to financial statements

The Funds do not generally isolate the effect of fluctuations in foreign exchange rates from the effect of the changes in market prices of securities. However, the Funds do isolate the effect of fluctuations in foreign exchange rates when determining the realized gain or loss upon the sale or maturity of foreign currency-denominated securities pursuant to US federal income tax regulations. Net realized foreign currency transaction gain (loss) is treated as ordinary income (loss) for income tax reporting purposes.

Concentration of risk: Investing in securities of foreign issuers and currency transactions may involve certain considerations and risks not typically associated with investments in the United States. These risks include revaluation of currencies, adverse fluctuations in foreign currency values and possible adverse political, social and economic developments, including those particular to a specific industry, country or region, which could cause the securities and their markets to be less liquid and prices more volatile than those of comparable US companies and US government securities. These risks are greater with respect to securities of issuers located in emerging market countries in which some Funds in the Trust invest.

Small capitalization ("small cap") companies may be more vulnerable than larger capitalization ("large cap") companies to adverse business or economic developments. Small cap companies may also have limited product lines, markets or financial resources, and may be dependent on a relatively small management group. Securities of such companies may be less liquid and more volatile than securities of large cap companies or the market averages in general and therefore may involve greater risk than investing in large cap companies. In addition, small cap companies may not be well-known to the investing public, may not have institutional ownership and may have only cyclical, static or moderate growth prospects.

The ability of the issuers of debt securities held by the Funds to meet their obligations may be affected by economic and political developments particular to a specific industry, country, state or region.

Investments in bonds with ratings of BB (Standard & Poor's Financial Services LLC or Fitch Ratings, Inc.) or Ba (Moody's Investors Service, Inc.) or below (commonly referred to as "high yield" bonds), or deemed of equivalent quality, have an increased risk of defaulting or otherwise being unable to honor a financial obligation. These securities are considered to be predominately speculative with respect to an issuer's capacity to pay interest and repay principal in accordance with the terms of the obligations. Lower-quality bonds are more likely to be subject to an issuer's default or downgrade than investment grade (higher-quality) bonds.

Valuation of investments

Each Fund generally calculates its net asset value on days that the New York Stock Exchange ("NYSE") is open. A Fund calculates net asset value separately for each class as of the close of regular trading on the NYSE (generally, 4:00 p.m., Eastern time). The NYSE normally is not open, and the Funds do not price their shares, on most national holidays and Good Friday. To the extent that a Fund's assets are traded in other markets on days when the NYSE is not open, the value of a Fund's assets may be affected on those days. If trading on the NYSE is halted for the day before 4:00 p.m., Eastern time, a Fund's net asset value per share generally will still be calculated as of the close of regular trading on the NYSE. The time at which a Fund calculates its net asset value and until which purchase, sale or exchange orders are accepted may be changed as permitted by the SEC.

Each Fund calculates its net asset value based on the current market value, where available, for its portfolio investments. The Funds normally obtain market values for their investments from independent pricing sources and broker-dealers. Independent pricing sources may use reported last sale prices, official market closing prices, current market quotations or valuations from computerized "evaluation" systems that derive values based on comparable investments. An evaluation system incorporates parameters such as security quality, maturity and coupon, and/or research and evaluations by its staff, including review of broker-dealer market price quotations, if available, in determining the valuation of the portfolio investments. Investments also may be valued based on appraisals derived from information concerning the investment or similar investments received from recognized dealers in those holdings.

122

The UBS Funds

Notes to financial statements

Investments traded in the over-the-counter ("OTC") market and listed on The NASDAQ Stock Market, Inc. ("NASDAQ") normally are valued at the NASDAQ Official Closing Price. Other OTC securities are valued at the last bid price on the valuation date available prior to valuation. Investments which are listed on US and foreign stock exchanges normally are valued at the market closing price, the last sale price on the day the securities are valued or, lacking any sales on such day, at the last available bid price. Investments listed on foreign stock exchanges may be fair valued based on significant events that have occurred subsequent to the close of the foreign markets. In cases where investments are traded on more than one exchange, the investments are valued on the exchange designated as the primary market by UBS AM. If a market value is not readily available from an independent pricing source for a particular investment, that investment is valued at fair value as determined in good faith by or under the direction of the Trust's Board of Trustees (the "Board"). Foreign currency exchange rates are generally determined as of the close of the NYSE.

Certain investments in which the Funds invest are traded in markets that close before 4:00 p.m., Eastern time. Normally, developments that occur between the close of the foreign markets and 4:00 p.m., Eastern time, will not be reflected in a Fund's net asset value. However, if any of the Funds determine that such developments are so significant that they will materially affect the value of the Fund's investments, the Fund may adjust the previous closing prices to reflect what is believed to be the fair value of these investments as of 4:00 p.m., Eastern time.

Certain Funds may use a systematic fair valuation model provided by an independent third party to value investments principally traded in foreign markets in order to adjust for possible stale pricing that may occur between the close of the foreign exchanges and the time for valuation. The systematic fair valuation model may use calculations based on indices of domestic securities and other appropriate indicators, such as prices of relevant ADRs and futures contracts. If an investment is valued at a "fair value," that value is likely to be different from the last quoted market price for the investment. The use of the fair valuation model may result in securities being transferred between Level 1 and Level 2 of the fair valuation hierarchy at the end of the reporting period. Transfers between Level 1 and Level 2, if any, are disclosed near the end of each Fund's Portfolio of investments.

The amortized cost method of valuation, which approximates market value, generally is used to value short-term debt instruments with 60 days or less remaining to maturity, unless the Board determines that this does not represent fair value.

Investments in open-end investment companies are valued at the daily closing net asset value of the respective investment company. Pursuant to the Funds' use of the practical expedient within ASC Topic 820, Fair Value Measurement, investments in investment companies without publicly published prices are also valued at the daily net asset value.

All investments quoted in foreign currencies are valued daily in US dollars on the basis of the foreign currency exchange rates prevailing at the time such valuation is determined by the Funds' custodian.

Futures contracts are generally valued at the settlement price established each day on the exchange on which they are traded. Forward foreign currency contracts are valued daily using forward exchange rates quoted by independent pricing services.

Swaps are marked-to-market daily based upon values from third party vendors or quotations from market makers to the extent available. In the event that market quotations are not readily available or deemed unreliable, the swap is valued at fair value as determined in good faith by or under the direction of the Board.

The Board has delegated to the Equities, Fixed Income, and Multi-Asset Valuation Committee ("VC") (formerly UBS AM Global Valuation Committee or GVC) the responsibility for making fair value determinations with respect to the Funds' portfolio holdings. The VC is comprised of representatives of management. The VC provides reports to the Board at each quarterly meeting regarding any investments that have been fair valued, valued pursuant to standing

123

The UBS Funds

Notes to financial statements

instructions approved by the VC, or where non-vendor pricing sources had been used to make fair value determinations when sufficient information exists during the prior quarter. Fair valuation determinations are subject to review at least monthly by the VC during scheduled meetings. Pricing decisions, processes, and controls over fair value determinations are subject to internal and external reviews, including annual internal compliance reviews and periodic internal audit reviews.

The types of investments for which such fair value pricing may be necessary include, but are not limited to: foreign investments under some circumstances; securities of an issuer that has entered into a restructuring; investments whose trading has been halted or suspended; fixed income securities that are in default and for which there is no current market value quotation; and investments that are restricted as to transfer or resale. The need to fair value a Fund's portfolio investments may also result from low trading volume in foreign markets or thinly traded domestic investments, and when a security that is subject to a trading limit or collar on the exchange or market on which it is primarily traded reaches the "limit up" or "limit down" price and no trading has taken place at that price. Various factors may be reviewed in order to make a good faith determination of an investment's fair value. These factors include, but are not limited to, fundamental analytical data relating to the investment; the nature and duration of restrictions on disposition of the investment; and the evaluation of forces which influence the market in which the investment is purchased and sold. Valuing investments at fair value involves greater reliance on judgment than valuing investments that have readily available market quotations. Fair value determinations can also involve reliance on quantitative models employed by a fair value pricing service.

US GAAP requires disclosure regarding the various inputs that are used in determining the value of each Fund's investments. These inputs are summarized into the three broad levels listed below:

Level 1—Unadjusted quoted prices in active markets for identical investments.

Level 2—Other significant observable inputs, including but not limited to, quoted prices for similar investments, interest rates, prepayment speeds and credit risk.

Level 3—Unobservable inputs inclusive of the Funds' own assumptions in determining the fair value of investments.

A fair value hierarchy table has been included near the end of each Fund's Portfolio of investments.

Investments

Securities traded on to-be-announced basis: Certain Funds may from time to time purchase, or short sell, securities on a to-be-announced ("TBA") basis. In a TBA transaction, the Fund commits to purchasing or selling securities for which all specific information is not yet known at the time of the trade, particularly the face amount and maturity date of the underlying securities. Securities purchased on a TBA basis are not settled until they are delivered to the Fund, normally 15 to 45 days later. Beginning on the date the Fund enters into a TBA transaction, cash, US government securities or other liquid securities are segregated in an amount equal in value to the purchase price of the TBA security. These transactions are subject to market fluctuations, and their current value is determined in the same manner as for other securities.

Mortgage-backed securities: Certain Funds may invest in mortgage-backed securities ("MBS"), representing direct or indirect interests in pools of underlying mortgage loans that are secured by real property. These securities provide investors with payments consisting of both principal and interest as the mortgages in the underlying mortgage pools are paid.

The timely payment of principal and interest (but not the market value) on MBS issued or guaranteed by Ginnie Mae (formally known as the Government National Mortgage Association or GNMA) is backed by Ginnie Mae and the full faith and credit of the US government. Obligations issued by Fannie Mae (formally known as the Federal National

124

The UBS Funds

Notes to financial statements

Mortgage Association or FNMA) and Freddie Mac (formally known as the Federal Home Loan Mortgage Corporation or FHLMC) are historically supported only by the credit of the issuer, but currently are guaranteed by the US government in connection with such agencies being placed temporarily into conservatorship by the US government.

Some MBS are sponsored or issued by private entities. Payments of principal and interest (but not the market value) of such private MBS may be supported by pools of mortgage loans or other MBS that are guaranteed, directly or indirectly, by the US government or one of its agencies or instrumentalities, or they may be issued without any government guarantee of the underlying mortgage assets but with some form of non-government credit enhancement.

Collateralized mortgage obligations ("CMO") are a type of MBS. A CMO is a debt security that may be collateralized by whole mortgage loans or mortgage pass-through securities. The mortgage loans or mortgage pass-through securities are divided into classes or tranches with each class having its own characteristics. Investors typically receive payments out of the interest and principal on the underlying mortgages. The portions of these payments that investors receive, as well as the priority of their rights to receive payments, are determined by the specific terms of the CMO class.

The yield characteristics of MBS differ from those of traditional debt securities. Among the major differences are that interest and principal payments are made more frequently, usually monthly, and that principal may be prepaid at any time because the underlying mortgage loans or other obligations generally may be prepaid at any time. Prepayments on a pool of mortgage loans are influenced by a variety of economic, geographic, social and other factors. Generally, prepayments on fixed-rate mortgage loans will increase during a period of falling interest rates and decrease during a period of rising interest rates. Certain classes of CMOs and other MBS are structured in a manner that makes them extremely sensitive to changes in prepayment rates. Such classes include interest-only ("IO") and principal-only ("PO") classes. IOs are entitled to receive all or a portion of the interest, but none (or only a nominal amount) of the principal payments, from the underlying mortgage assets. If the mortgage assets underlying an IO experience greater than anticipated principal prepayments, then the total amount of interest payments allocable to the IO class, and therefore the yield to investors, generally will be reduced. Conversely, PO classes are entitled to receive all or a portion of the principal payments, but none of the interest, from the underlying mortgage assets. PO classes are purchased at substantial discounts from par, and the yield to investors will be reduced if principal payments are slower than expected.

Asset-backed securities: Certain Funds may invest in asset-backed securities ("ABS"), representing interests in pools of certain types of underlying installment loans, home equity loans, leases of various types of real and personal property and receivables from revolving lines of credit (credit cards). Such assets are securitized through the use of trusts or special purpose corporations. The yield characteristics of ABS differ from those of traditional debt securities. One such major difference is that principal may be prepaid at any time because the underlying obligations generally may be prepaid at any time. ABS may decrease in value as a result of increases in interest rates and may benefit less than other fixed-income securities from declining interest rates because of the risk of prepayment.

Short sales: UBS Dynamic Alpha Fund, UBS U.S. Small Cap Growth Fund and UBS Total Return Bond Fund may engage in short sale transactions in which the Fund sells a security it does not own (or does not have the right to acquire at no added cost), in anticipation of a decline in the security's price.

The Fund must borrow the security to make delivery to the buyer. The initial amount of a short sale is recorded as a liability which is marked to market daily. Fluctuations in the value of this liability are recorded as unrealized appreciation or depreciation on the Statement of operations. The Fund will realize a loss as a result of the short sale if the price of the security increases between the date of the short sale and the date on which the Fund replaces the borrowed security, and the Fund will realize a gain if the security declines in price between those same dates. Each Fund segregates collateral, consisting of cash or liquid assets, sufficient to collateralize the market value of the investments sold short. Each Fund incurs transaction costs, including dividend expense, borrowing costs and interest

125

The UBS Funds

Notes to financial statements

expenses in connection with opening, maintaining and closing short sales. These dividends and interest are booked as an expense or liability to the Fund.

Because a Fund's loss on a short sale arises from increases in the value of the investment sold short, such loss, like the potential increase in price of the security sold short, is theoretically unlimited. The Fund's investments held long could also decline in value at the same time the value of the investment sold short increases, thereby increasing the Fund's potential for loss. There is also the risk that the counterparty to a short sale transaction may fail to honor its contract terms, causing a loss to the Fund.

For the period ended June 30, 2017, UBS Dynamic Alpha Fund, UBS U.S. Small Cap Growth Fund and UBS Total Return Bond Fund did not engage in short sale transactions.

Restricted securities: The Funds may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expenses, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities, if any, is included in each Fund's portfolio footnotes.

Derivative instruments

Purchased options: Certain Funds may purchase put and call options, including, but not limited to, options on foreign or US securities, indices, foreign currencies and options on swap agreements (commonly referred to as swaptions), in order to gain exposure to or protect against changes in the markets or in an attempt to enhance income or gains. Purchasing call options tends to increase exposure to the underlying instrument. Purchasing put options tends to decrease exposure to the underlying instrument.

The Fund pays a premium which is included in the Statement of assets and liabilities as an investment and subsequently marked-to-market to reflect the current value of the option. Premiums paid for purchasing options which expire are treated as realized losses. Purchased options are shown as portfolio holdings within the Portfolio of investments and are included in the Statement of assets and liabilities in investments of unaffiliated issuers, at value.

The risk associated with purchasing put and call options is limited to the premium paid. Premiums paid for purchasing options which are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying future, security or currency transaction to determine the realized gain or loss.

Option writing: Certain Funds may write (sell) put and call options, including, but not limited to, options on foreign or US securities, indices, foreign currencies and options on swap agreements (commonly referred to as swaptions), in order to gain exposure to or protect against changes in the markets or in an attempt to enhance income or gains.

When a Fund writes a call or a put option, an amount equal to the premium received by the Fund is included in the Fund's Statement of assets and liabilities as a liability. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written. If an option which a Fund has written either expires on its stipulated expiration date or the Fund enters into a closing purchase transaction, the Fund realizes a gain (or a loss if the cost of a closing purchase transaction exceeds the premium received when the option was written) without regard to any unrealized gain or loss on the underlying security or derivative instrument, and the liability related to such option is extinguished. If a call option, which a Fund has written, is exercised, the Fund recognizes a realized gain or loss (long-term or short-term, depending on the holding period of the underlying security) from the sale of the underlying security or derivative instrument and the proceeds from the sale are increased by the premium originally received. If a put option, which a Fund has written, is exercised, the amount of the premium originally received reduces the cost of the security or derivative instrument which the Fund purchases upon exercise of the option.

126

The UBS Funds

Notes to financial statements

In writing an option, a Fund bears the market risk of an unfavorable change in the price of the derivative instrument, security, or currency underlying the written option. Exercise of an option written by a Fund could result in the Fund selling or buying a derivative instrument, security or currency at a price different from current market value.

In the normal course of trading activities, the Funds trade and hold certain fair valued derivative contracts that constitute guarantees. Such contracts include written put options, where the Funds would be obligated to purchase securities at specified prices (i.e. the options are exercised by the counterparties). The maximum payout for these contracts is limited to the number of put option contracts written and the related strike prices, respectively. Maximum payout amounts could be offset by the subsequent sale, if any, of assets obtained via the execution of a payout event. At June 30, 2017, none of the Funds held written put options.

Futures contracts: Certain Funds may purchase or sell futures contracts to increase or reduce their exposure to an asset class without purchasing or selling the underlying securities, either as a hedge or to enhance income or realized gains. Generally, a futures contract is a standard binding agreement to buy or sell a specified quantity of an underlying reference asset, such as a specific security or currency, at a specified price at a specified later date.

Upon entering into a futures contract, a Fund is required to deliver to a broker an amount of cash and/or US government securities equal to a certain percentage of the contract amount. This amount is known as the "initial margin". Subsequent payments, known as "variation margin", generally are made or received by a Fund, depending on the daily fluctuations in the value of the underlying futures contracts. Such variation margin is recorded for financial statement purposes on a daily basis as an unrealized appreciation or depreciation on futures until the futures contract is closed or expires, at which time the net gain or loss is reclassified to realized gain or loss on futures.

Using futures contracts involves various market risks, including interest rate and equity risk. Risks of entering into futures contracts include the possibility that there may be an illiquid market or that a change in the value of the contract may not correlate with changes in the value of the underlying securities. To the extent that market prices move in an unexpected direction, there is a risk that a Fund will not achieve the anticipated benefits of the futures contract or may realize a loss.

Forward foreign currency contracts: Certain Funds may enter into forward foreign currency contracts in order to expedite settlement of portfolio transactions, manage currency risk or to gain exposure to a currency without purchasing securities denominated in that currency. Generally, a forward foreign currency contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated forward rate. Non-deliverable forward foreign currency contracts are settled with the counterparty in US dollars, or another fully convertible currency, without the physical delivery of foreign currency.

Fluctuations in the value of open forward foreign currency contracts are recorded daily for book purposes as unrealized appreciation or depreciation on forward foreign currency contracts by the Funds. Realized gains and losses on forward foreign currency contracts include net gains or losses recognized by the Funds on contracts which have been sold or matured.

Risks may arise upon entering into forward foreign currency contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of foreign currencies relative to the US dollar or each other.

Swap agreements: Certain Funds may engage in swap agreements, including, but not limited to, interest rate, credit default and total return swap agreements. A Fund expects to enter into these transactions to preserve a return or spread on a particular investment or to hedge a portion of the portfolio's duration, to protect against any increase in the price of securities the Fund anticipates purchasing at a later date, to gain exposure to certain markets in the most economical way possible or in an attempt to enhance income or gains.

127

The UBS Funds

Notes to financial statements

The Funds accrue for interim payments on swap agreements on a daily basis, with the net amount recorded within unrealized appreciation or depreciation of swap agreements. Once interim payments are settled in cash, the net amount is recorded as realized gain/loss on swap agreements, in addition to realized gain/loss recorded upon the termination of swap agreements on the Statement of operations. Fluctuations in the value of swap agreements are recorded for financial statement purposes as unrealized appreciation or depreciation on swap agreements.

Certain Funds may enter into interest rate swap agreements with another party to receive or pay interest (e.g., an exchange of fixed rate payments for floating rate payments) to protect themselves from interest rate fluctuations. This type of swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to a specified interest rate(s) for a specified amount. The payment flows are usually netted against each other, with the difference being paid by one party to the other. Interest rate swap agreements are subject to general market risk, liquidity risk, counterparty risk and interest rate risk.

Credit default swap agreements involve commitments to make or receive payments in the event of a default of a security or other credit event of the referenced obligation. As a buyer, the Fund would make periodic payments to the counterparty, and the Fund would receive payments only upon the occurrence of a default or credit event. If no default or credit event occurs, the Fund will lose its periodic stream of payments over the term of the contract. However, if a default or a credit event does occur, the Fund typically would receive full notional value for the referenced obligation that may have little or no value. As a seller, the Fund would receive periodic payments from the counterparty, and the Fund would make payments only upon the occurrence of a default or a credit event. If no default or credit event occurs, the Fund will gain the periodic stream of payments it received over the term of the contract and the counterparty will lose its periodic stream of payments over the term of the contract. However, if a default or credit event occurs, the Fund typically would pay full notional value for the referenced obligation that may have little or no value. Credit default swap agreements may involve greater risks than if the Fund had invested in the referenced obligation directly and are subject to general market risk, liquidity risk and credit risk.

Credit default swap agreements on credit indices involve one party making a stream of payments to another party in exchange for the right to receive a specified return in the event of a write-down, principal shortfall, interest shortfall or default of all or part of the referenced entities comprising the credit index. A credit index is a list of a basket of credit instruments or exposures designed to be representative of some part of the credit market as a whole. These indices are made up of referenced credits that are judged by a poll of dealers to be the most liquid entities in the credit default swap market based on the sector of the index. Components of the indices may include, but are not limited to, investment grade securities, high yield securities, asset backed securities, emerging markets, and/or various credit ratings within each sector. Credit indices are traded using credit default swaps with standardized terms including a fixed spread and standard maturity dates. An index credit default swap references all the names in the index, and if there is a default, the credit event is settled based on that name's weight in the index. The composition of the indices changes periodically, usually every six months, and for most indices, each name has an equal weight in the index. A Fund may use credit default swap agreements on credit indices to hedge a portfolio of credit default swaps or bonds with a credit default swap on indices which is less expensive than it would be to buy many credit default swaps to achieve a similar effect. Credit default swap agreements on credit indices are benchmarks for protecting investors owning bonds against default, and traders use them to speculate on changes in credit quality.

Credit default swap agreements on corporate issues or sovereign issues of an emerging market country involve one party making a stream of payments to another party in exchange for the right to receive a specified return in the event of a default or other credit event. If a credit event occurs and cash settlement is not elected, a variety of other obligations may be delivered in lieu of the specific referenced obligation. The ability to deliver other obligations may result in a cheapest-to-deliver option (the buyer of protection's right to choose the deliverable obligation with the lowest value following a credit event). A Fund may use credit default swap agreements on corporate issues or sovereign issues of an emerging market country to provide a measure of protection against defaults of the issuers (i.e., to

128

The UBS Funds

Notes to financial statements

reduce risk where the Fund owns or has exposure to the referenced obligation) or to take an active long or short position with respect to the likelihood of a particular issuer's default.

The maximum potential amount of future payments (undiscounted) that a Fund as a seller of protection could be required to make under a credit default swap agreement would be an amount equal to the notional amount of the agreement, which may exceed the amount of the value reflected on the Statement of assets and liabilities. Notional amounts of all credit default swap agreements outstanding as of the period end for which a Fund is the seller of protection are disclosed under the section "Credit default swap agreements on corporate issues—sell protection" in the Portfolio of investments. These potential amounts would be partially offset by any recovery values of the respective referenced obligations, upfront payments received upon entering into the agreement, or net amounts received from the settlement of buy protection credit default swap agreements entered into, if any, by a Fund for the same referenced entity or entities.

Total return swap agreements involve commitments to pay or receive interest in exchange for a market-linked return based on a notional amount. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, the Fund will receive a payment from or make a payment to the counterparty, respectively. Total return swap agreements are marked-to-market daily, and the change, if any, is recorded as unrealized appreciation or depreciation. Total return swap agreements are subject to general market risk, liquidity risk, counterparty risk, interest rate risk, credit risk and the risk that there may be unfavorable changes in the underlying investments or instruments.

The use of swap agreements involves investment techniques and risks different from those associated with ordinary portfolio security transactions. If UBS AM is incorrect in its forecast of market values, interest rates and other applicable factors, the investment performance of the Fund will be less favorable than it would have been if this investment technique was never used. OTC swap agreements do not involve the delivery of securities and are subject to counterparty risk. If the other party to a swap agreement defaults and fails to consummate the transaction, a Fund's risk of loss will consist of the net amount of interest or other payments that the Fund is contractually entitled to receive. Therefore, the Fund would consider the creditworthiness of the counterparty to a swap agreement in evaluating potential credit risk.

Certain clearinghouses offer clearing for limited types of derivatives transactions, such as interest rate and credit default swap agreements. Centrally cleared swap agreements must be transacted through a futures commission merchant ("FCM") and cleared through a clearinghouse that serves as a central counterparty. The performance of a centrally cleared swap transaction is effectively guaranteed by a central clearinghouse, thereby reducing the Fund's exposure to the credit risk of its original counterparty. The Fund will be required to post specified levels of margin with the clearinghouse or at the instruction of the clearinghouse; the margin required by a clearinghouse may be greater than the margin the Fund would be required to post in an uncleared transaction. Centrally cleared swap agreements, if any, are reported on the Statement of assets and liabilities based on variation margin receivable or payable, if any.

Derivatives by underlying risk: Investment companies value their derivatives at fair value and recognize changes in fair value through the Statement of operations. Under US GAAP, investment companies do not qualify for hedge accounting. Accordingly, even though a Fund's investments in derivatives may represent economic hedges, they are considered to be non-hedge transactions for purposes of disclosure under US GAAP.

The volume of derivatives as disclosed in each Fund's Portfolio of investments is representative of the volume of derivatives outstanding during the period ended June 30, 2017.

Swap agreements, forward foreign currency contracts, swaptions and options written entered into by the Funds may contain credit-risk related contingent features that could be triggered subject to certain circumstances. Such circumstances include agreed upon net asset value thresholds. If triggered, the derivative counterparty could request

129

The UBS Funds

Notes to financial statements

additional cash margin and/or terminate the derivative contract. The aggregate fair value of the derivative contracts that are in a net liability position that contain these triggers can be found in the Portfolio of investments. The aggregate fair value of assets that are already posted as collateral as of June 30, 2017 is reflected in the Statement of assets and liabilities.

At June 30, 2017, the Fund had the following derivatives categorized by underlying risk:

Offsetting of certain derivatives: The Funds typically enter into International Swaps and Derivatives Association, Inc. Master Agreements ("ISDA Master Agreements") or similar master agreements with its OTC derivative contract counterparties in order to, among other things, reduce its credit risk to counterparties. ISDA Master Agreements include provisions for general obligations, representations, collateral and events of default or termination. Under an ISDA Master Agreement, the Funds typically may offset with the counterparty certain derivative financial instrument's payables and/or receivables with collateral held and/or posted and create one single net payment (close-out netting) in the event of default or termination. The Statement of assets and liabilities is presented gross of any netting.

At June 30, 2017, derivative assets and liabilities (by type) on a gross basis and derivatives subject to an enforceable master netting arrangement ("MNA") or similar agreement were follows:

Securities lending

Each Fund may lend securities up to 33¹/₃% of its total assets to qualified broker-dealers or institutional investors. When loaning portfolio securities, each Fund will initially require the borrower to provide the Fund with collateral in an amount at least equal to 102% of the market value of the loaned securities with respect to domestic securities or 105% of the market value of the loaned securities with respect to foreign securities, provided that loans of "Government Securities" as defined in the 1940 Act may be collateralized at 100%. Thereafter, collateral will generally be maintained in an amount at least equal to 102% of the value of the securities loaned with respect to domestic securities, 105% of the value of the securities loaned with respect to foreign securities, or 100% of the value of the securities loaned with respect to "Government Securities." Occasionally, for certain securities, the market value of the collateral may fall below the collateral amount stated above by a de minimis amount for a period of time. However, at no time will the market value of the collateral fall below the market value of the loaned securities with respect to domestic securities or 102% of the value of the loaned securities with respect to foreign securities.

Each Fund will regain ownership of loaned securities to exercise certain beneficial rights; however, the Fund may bear the risk of delay in recovery of, or even loss of rights in, the securities loaned should the borrower fail financially. Each Fund receives compensation for lending its securities from interest or dividends earned on the cash, US government or government agency securities or, under certain conditions, bank letters of credit held as collateral, net of fee rebates paid to the borrower plus reasonable administrative and custody fees. Cash collateral received is invested in JPMorgan U.S. Government Money Market Fund, which is included in each Fund's Portfolio of investments. JPMorgan Chase Bank serves as the Funds' lending agent.

At June 30, 2017, the following Funds had securities on loan at value, cash collateral and non-cash collateral as follows:

Fund	Market value of securities loaned		Total market value of collateral received for securities loaned		Market value of cash collateral received		Market value of non-cash collateral received		Security type held as non-cash collateral

Notes to financial statements

The table below represents the disaggregation at June 30, 2017 of the gross amount of recognized liabilities for securities lending transactions. As the securities loaned are subject to termination by the Funds or the borrower at any time, the remaining contractual maturities of the transactions presented below are considered to be overnight and continuous.

Bank line of credit

The Funds participate with other funds managed by UBS AM in a $50 million committed credit facility (the "Committed Credit Facility") with JPMorgan Chase Bank. The Committed Credit Facility is to be utilized for temporary financing until the settlement of sales or purchases of portfolio securities, the repurchase or redemption of shares of a participating Fund at the request of shareholders and other temporary or emergency purposes.

Interest on amounts borrowed is calculated based on the prevailing rates in effect at the time of borrowing. Each Fund covered by the Committed Credit Facility has agreed to pay commitment fees on the average daily balance of the Committed Credit Facility not utilized. Commitment fees have been allocated among the Funds in the Committed Credit Facility as follows: 50% of the allocation is based on the relative asset size of Funds and the other 50% of the allocation is based on utilization. For the period ended June 30, 2017, the Funds had no borrowings under the Committed Credit Facility.

Commission recapture program

Certain Funds participate in a brokerage commission recapture program. These Funds have established commission recapture arrangements with certain participating brokers or dealers. If a Fund's investment manager chooses to execute a transaction through a participating broker subject to best price and execution, the broker will rebate a portion of the commission back to the Fund. Any collateral benefit received through participation in the commission recapture program is directed exclusively to the Fund. For the period ended June 30, 2017, the following Funds recorded recaptured commissions which are reflected in the Statement of operations within the net realized gains (losses) on investments in unaffiliated issuers:

Fund	Amount
UBS Global Allocation Fund	$	1,896

Redemption fees

Effective August 3, 2015, the redemption fee of 1.00% imposed by each class of each series of The UBS Funds, with the exception of UBS Total Return Bond Fund, was eliminated. Prior to August 3, 2015 for purchases of shares on or after February 17, 2015, the redemption fee was calculated as a percentage of the amount redeemed within 30 days of purchase, if applicable.

The Board of Trustees approved a temporary redemption fee of 2.00% following the reorganization of Fort Dearborn Income Securities, Inc. with UBS Total Return Bond Fund. The temporary redemption fee was paid to the UBS Total Return Bond Fund and was in effect until August 22, 2016.

The redemption fees retained by the Funds are disclosed in the Statement of changes in net assets. For the period ended June 30, 2017, redemption fee represented less than $0.005 per share.

Federal tax status

It is each Fund's policy to comply with all requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of their taxable income to their shareholders. In addition, by distributing during each calendar year substantially all of its net investment income, net realized capital gains and certain other amounts, if any, each Fund intends not to be subject to a federal excise tax. Accordingly, no federal income tax provision was required.

The tax character of distributions paid during the fiscal years ended June 30, 2017 and June 30, 2016 were as follows:

	2017

¹  For the period from October 1, 2015 through June 30, 2016.

At June 30, 2017, the components of accumulated earnings (deficit) on a tax basis were as follows:

Fund	Undistributed ordinary income		Undistributed long-term capital gains		Accumulated capital and other losses			Unrealized appreciation/ (depreciation)			Total
UBS Dynamic Alpha Fund	$	—	$	—	$	(280,396,331	)	$	(11,279,295	)	$	(291,675,626	)

UBS Municipal Bond Fund		—		—		(884,268	)		726,852		$	(157,416	)

The difference between book and tax basis net unrealized appreciation (depreciation) of investments is primarily attributable to mark to market of passive foreign investment companies, non-taxable special dividends, return of capital from investments in real estate investment trusts, tax treatment of certain debt instruments and tax deferral of losses on wash sales.

Under the Regulated Investment Company Modernization Act of 2010 (the "Act"), net capital losses recognized by the Funds after December 22, 2010, may be carried forward indefinitely, and retain their character as short-term and/or long-term losses. These carryforwards are available as a reduction, to the extent provided in regulations, of future realized capital gains. To the extent that such losses are used to offset future net realized capital gains, it is probable these gains will not be distributed. The Act requires that post-enactment net capital losses be used before pre-enactment net capital losses.

At June 30, 2017, the following Funds had post-enactment net capital losses that will be carried forward indefinitely, as follows:

Fund	Short-term losses		Long-term losses		Net capital losses
UBS Dynamic Alpha Fund	$	15,697,248	$	13,788,961	$	29,486,209

Notes to financial statements

These differences are primarily due to the tax treatment of foreign currency transactions, paydown gains and losses, tax character distributions, the tax treatment of certain derivatives, non-taxable special dividends, passive foreign investment company gains and losses, net operating losses, expiration of capital loss carryforwards, tax treatments of certain debt instruments and partnership adjustments.

ASC 740-10 "Income Taxes—Overall" sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken. The Funds have conducted an analysis and concluded, as of June 30, 2017, that there are no significant uncertain tax positions taken or expected to be taken that would require recognition in the financial statements. It is each Fund's policy to record any significant foreign tax exposures in the financial statements. The Funds recognize interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statement of operations. During the year ended June 30, 2017, the Funds did not incur any interest or penalties.

Under the applicable foreign tax laws, gains on certain securities held in certain foreign countries may be subject to taxes that will be paid by the Funds.

Each of the tax years in the four year fiscal period ended June 30, 2017 or since inception in the case of UBS Municipal Bond Fund, remains subject to examination by the Internal Revenue Service and state taxing authorities.

Subsequent events

In June 2017, the Board of Trustees of The UBS Funds approved a name change and investment policy modifications for the UBS U.S. Large Cap Equity Fund (the "Fund") that will go into effect on or about October 27, 2017. The Fund's name will change to the UBS U.S. Sustainable Equity Fund. The Fund will modify part of its investment strategy, such that under normal circumstances the Fund will invest at least 80% of its net assets (plus borrowings for investment purposes, if any) in equity securities of US companies (previously, equity securities of US large capitalization companies). Additionally, the Fund's benchmark will change from the Russell 1000 Index to the S&P 500 Index.

Our procedures included confirmation of securities owned as of June 30, 2017, by correspondence with the custodian and others or by other appropriate auditing procedures where replies from others were not received. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of UBS Dynamic Alpha Fund, UBS Global Allocation Fund, UBS International Sustainable Equity Fund, UBS U.S. Large Cap Equity Fund, UBS U.S. Small Cap Growth Fund, UBS Total Return Bond Fund and UBS Municipal Bond Fund at June 30, 2017, the results of their operations for the year then ended, the changes in their net assets and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles.

Board approval of investment advisory agreements (unaudited)

At the meeting of the Board of Trustees (the "Board") of The UBS Funds (the "Trust"), held on June 15 and 16, 2017 (the "Meeting"), the Board, including those Trustees who are not "interested persons" (as defined in the 1940 Act) of the Trust or UBS Asset Management (Americas) Inc. (the "Advisor") and its affiliates (together, the "Independent Trustees"), considered the continuation of the investment advisory agreements (the "Advisory Agreements") between the Trust and the Advisor for the UBS Dynamic Alpha Fund, UBS Global Allocation Fund, UBS International Sustainable Equity Fund, UBS U.S. Large Cap Equity Fund, UBS U.S. Small Cap Growth Fund, UBS Total Return Bond Fund and UBS Municipal Bond Fund (each a "Fund," and together, the "Funds"). Prior to the Meeting, the Independent Trustees' counsel had sent to the Advisor a request detailing the information that the Independent Trustees wished to receive in connection with their consideration of the continuation of the Advisory Agreements. The Independent Trustees met with their independent counsel, as well as an independent consultant engaged by the Board to assist in the annual Advisory Agreement review process, on June 9, 2017, June 15, 2017 and June 16, 2017, to discuss the materials provided to them in response to the information request, including materials prepared by the Advisor, as well as reports prepared by Broadridge Financial Solutions, Inc. ("Broadridge Reports"), an independent statistical compilation company, providing comparative expense information on an actual and contractual basis and comparative performance information for the Funds. The Board also made reference to information and material that had been provided to the Independent Trustees throughout the year at quarterly Board meetings.

At the Meeting, the Board considered a number of factors in connection with its deliberations concerning the continuation of the Advisory Agreement for each Fund, including: (i) the nature, extent, and quality of the services provided by the Advisor to the Fund; (ii) the performance of the Fund and the Advisor; (iii) the Fund's expenses, costs of the services to be provided and profits to be realized by the Advisor and its affiliates from the relationship with the Fund; and (iv) whether economies of scale are realized by the Advisor with respect to the Fund, as it grows larger, and the extent to which the economies of scale are reflected in the level of the management fees charged.

Nature, Extent, and Quality of Services.

In considering the nature, extent, and quality of the services provided by the Advisor to a Fund, the Board reviewed the material presented by the Advisor describing the various services provided to each Fund. The Board noted that in addition to investment management services, the Advisor provides each Fund with operational, legal, and compliance support. The Board also considered the scope and depth of the Advisor's organization and the experience and expertise of the professionals currently providing investment management and other services to the Funds. The Board considered that the Advisor was a well-established investment management organization employing investment personnel with significant experience in the investment management industry. The Board also considered the Advisor's in-house research capabilities, as well as other research services available to it, including research services available to the Advisor as a result of securities transactions effected for the Funds and the Advisor's other investment management clients, and noted that the Advisor had extensive global research capabilities. The Board also evaluated the Advisor's portfolio management process for each Fund, including the use of risk management techniques and the proprietary technologies utilized to structure the Fund's portfolio. The Board noted that various presentations had been made by investment personnel at Board meetings throughout the year concerning the Funds' investment performance and investment strategies, including the derivative strategies utilized by certain Funds.

The Board also noted and discussed the services that the Advisor and its affiliates provide to the Funds under other agreements with the Trust, including administration services provided by the Advisor, underwriting services provided by UBS Asset Management (US) Inc. ("UBS AM (US)"), and sub-transfer agency services provided by UBS Financial Services Inc. ("UBS Financial Services"). In connection with the non-investment management services, the Board also considered the quarterly reports that the Advisor provides to the Board throughout the year pertaining to brokerage commissions, soft dollars, portfolio valuations, and Rule 12b-1 fees, among others. In addition, the Board considered the presentations provided with respect to distribution strategies for the Funds. After analyzing the serv-

152

The UBS Funds

Board approval of investment advisory agreements (unaudited) (continued)

ices provided by the Advisor to each Fund, both quantitatively and qualitatively, including the impact of these services on investment performance, the Board concluded that the nature, extent, and quality of services provided to each Fund were consistent with the operational requirements of each Fund, and met the needs of the Fund's shareholders.

Performance.

In evaluating the performance of each Fund, the Board analyzed the Broadridge Reports, which compared the performance of each Fund with other funds in its respective peer universe over various time periods. The Board also reviewed the memoranda provided by the Advisor providing an analysis of the markets and the Funds' performance during the past year. In reviewing the Broadridge Reports, the Board noted that the UBS U.S. Large Cap Equity Fund and UBS U.S. Small Cap Growth Fund each had appeared in the top performance quintile for the one-year performance period. The Board also noted that the UBS Municipal Bond Fund and UBS Total Return Bond Fund each had appeared in the second performance quintile of its respective performance universe for the one-year performance period, while the UBS International Sustainable Equity Fund appeared in the third performance quintile of its performance universe for the one-year period. At the Board's request, the Advisor further addressed the performance data for the UBS Dynamic Alpha Fund and UBS Global Allocation Fund, each of which had appeared in fourth performance quintile for the one-year period.

In discussing the performance of the UBS Dynamic Alpha Fund for the one-year performance period, the Advisor explained that some of the Fund's duration positons in U.S. and Australian government bonds and several emerging market currency positions detracted from the Fund's performance. The Advisor also stated that several of the Fund's relative value trades were out of favor in the beginning part of the year but moved closer to expectations more recently. The Advisor noted that for the most recent three-months ended May 31, 2017, the UBS Dynamic Alpha Fund was outperforming the average of its performance peer universe. The Advisor then discussed planned enhancements to the investment process for the UBS Dynamic Alpha Fund that should help to address the performance issues of the Fund.

In explaining the performance of the UBS Global Allocation Fund, the Advisor discussed the factors that had affected the performance of the Fund over the past year. The Advisor noted that both market allocation and security selection detracted from the Fund's performance over the past year. The Advisor explained that the Fund's equity positions had the most negative effect on the Fund's returns. The Advisor then noted that the Fund's most recent performance had rebounded, noting that for the one-year period ending May 31, 2017, the UBS Global Allocation Fund was outperforming the average of its performance peer universe.

The Board concluded that the Advisor's explanations provided a sound basis for understanding the performance of each Fund that underperformed in comparison to its peer universe. The Board determined, after analyzing the performance data, that the performance of each Fund was acceptable as compared with relevant performance standards, given the investment strategies and risk profile of each Fund, the expectations of the shareholder base and the current market environment.

Fund Fees and Expenses.

When considering the fees and expenses borne by each Fund, and the reasonableness of the management fees paid to the Advisor in light of the services provided to each Fund, the Board compared the fees charged by the Advisor to each Fund to fees charged to the funds in its peer group for comparable services, as provided in the Broadridge Reports, on both an actual (taking into account expense limitation arrangements) and a contractual basis (assuming all funds in the peer expense group were similar in size to the respective Fund).

153

The UBS Funds

Board approval of investment advisory agreements (unaudited) (continued)

In examining the Broadridge Reports, and in reviewing comparative costs, it was noted that each Fund had a contractual fee rate higher than the Broadridge median in its respective Broadridge expense group. The Advisor noted, however, that while each Fund's contractual fee rate was higher than its respective peer expense group median, the UBS U.S. Large Cap Equity Fund, UBS Total Return Bond Fund and UBS Municipal Bond Fund, each had a contractual fee rate within three basis points of its Broadridge median. The Advisor also noted that the results of such expense comparisons showed that the actual management fee rate for each Fund, except the UBS Global Allocation Fund and UBS Dynamic Alpha Fund, was lower than the Broadridge median in its respective Broadridge expense group, and each appeared in the top quintile of its expense group. In addition, the Board reviewed the actual total expenses of each Fund and noted that each Fund had total expenses that were comparable to, or lower than, the Broadridge median in its respective Broadridge expense group, except for the UBS Dynamic Alpha Fund and UBS Global Allocation Fund. After reviewing the fee and expense information, the Board asked the Advisor to further discuss the fees and expenses of the UBS Dynamic Alpha Fund and UBS Global Allocation Fund, which both had contractual fee rates, actual fee rates and total expenses that were higher than each of their respective Broadridge expense group medians.

The Advisor and the Board first discussed the management fee and expenses of the UBS Dynamic Alpha Fund. It was noted that in recent years while the contractual management fee and actual management fee were each higher than the medians in its Broadridge expense group, the UBS Dynamic Alpha Fund's total expenses were in-line with its peers, resulting in the total costs to investors being very competitive. It was noted that in this year's comparison, the Fund's total expenses were higher than the expense group median. At the request of the Board, the Advisor explained the reasons for the less favorable comparative total expenses, noting the small size of the Fund and changes in the composition of the expense group. The Advisor discussed with the Board those funds within the expense group that it considered to be the UBS Dynamic Alpha Fund's key competitors. The Advisor noted that among these key competitors, UBS Dynamic Fund's total expenses were very competitive. The Advisor and the Board agreed to continue to monitor the Fund's peers and expenses.

The Advisor and the Board next discussed the management fee and expenses of the UBS Global Allocation Fund. It was noted that the Board approved a new fee waiver and expense cap arrangement for the Fund that was effective October 28, 2016. The Advisor explained that the Broadridge report did not entirely reflect the effect of the new expense cap, and if the expense cap had been fully reflected in the expense comparison, the total expenses of the UBS Global Allocation Fund would have been below its Broadridge expense group median.

The Board also received and considered information about the fee rates charged to other funds and accounts that are managed by the Advisor. After discussing the information about the other funds and accounts with the Advisor, the Board determined that the fees charged by the Advisor to the Funds were within a reasonable range, giving effect to differences in services performed for such other funds and accounts as compared to such fee rates. The Board, after reviewing all pertinent material, concluded that the management fee payable under each Fund's Advisory Agreement was fair and reasonable, both on an absolute basis and in comparison with the fees of other funds identified in its peer group.

Costs and Profitability.

The Board considered the costs of providing services to the Funds and the profitability of the Funds to the Advisor and its affiliates by reviewing the profitability analysis provided by the Advisor, including information about its fee revenues and expenses. The Board reviewed the profitability of each Fund to the Advisor and its affiliates, and the compensation that was received for providing services to each Fund. The profitability analysis, which provided information for the last three calendar years, included schedules relating to the revenue and expenses attributable to: (i) the investment advisory and administration services provided by the Advisor; (ii) the distribution and shareholder services provided by UBS AM (US) and UBS Financial Services; (iii) the transfer agency-related services provided by

154

The UBS Funds

Board approval of investment advisory agreements (unaudited) (concluded)

UBS Financial Services; and (iv) all services provided by the Advisor, UBS AM (US), and UBS Financial Services shown on a consolidated basis. In discussing the profitability analysis with the Board, the Advisor, as requested by the Board, provided the Board with a presentation on the methodology utilized in the profitability analysis. The Board noted that the methodology used for the profitability analysis provided to the Board for purposes of its annual review of the Advisory Agreements was reasonable. The Advisor also explained to the Board the reasons for an increase or decrease in profitability of each Fund from last calendar year to this calendar year.

The Board also considered "fallout" or ancillary benefits to the Advisor or its affiliates as the result of their relationship with the Funds; for example, the ability to attract other clients due to the Advisor's role as investment advisor to the Funds and the research services available to the Advisor through soft dollar brokerage commissions. The Independent Trustees also considered the ancillary benefits received by the Advisor's affiliates, UBS Securities LLC and UBS Group AG, in the form of commissions for executing securities transactions for the Funds. Upon closely examining the information provided concerning the Advisor's profitability, the Board concluded that the level of profits realized by the Advisor and its affiliates with respect to each Fund, if any, was reasonable in relation to the nature and quality of the services that were provided.

Economies of Scale.

The Board also discussed whether economies of scale are realized by the Advisor with respect to each Fund as it grows larger, and the extent to which this is reflected in the level of management fees charged. The Board noted that with respect most Funds, any actual or potential economies of scale are, or will be, shared with the Fund and its shareholders through existing management fee breakpoints so that as the Fund grows in size, its effective management fee declines. The Board noted that each Fund, except the UBS Total Return Bond Fund and UBS Municipal Bond Fund, had a breakpoint schedule that provided for continuing breakpoints past the current asset level for the Fund. Based on each Fund's fees and expenses and the Advisor's profitability analysis, the Board concluded that any actual or potential economies of scale would be reasonably shared with a Fund and its shareholders.

After full consideration of the factors discussed above, with no single factor identified as being of paramount importance, the Board, including a majority of the Independent Trustees, with the assistance of independent counsel, concluded that the continuation of the Advisory Agreement for each Fund was in the best interests of the Fund and its shareholders.

The Audit Committee Charter contains the Audit Committee’s pre-approval policies and procedures.  Reproduced below is an excerpt from the Audit Committee Charter regarding pre-approval policies and procedures:

To carry out its purposes, the Audit Committee shall have the following duties and powers:

In evaluating the auditor’s qualifications performance and independence, the Committee must, among other things, obtain and review a report by the auditors, at least annually, describing the following items: (i) all relationships between the, independent auditors and the UBS Funds, as well as with the UBS Funds, investment advisor or any control affiliate of the investment advisor that provides ongoing services to the UBS Funds; (ii) any material issues raised by the most recent internal quality control review, or peer review, of the audit firm, or by any inquiry or investigation by governmental or professional authorities, within the preceding five years, with respect to one or more independent audits carried out by the firm, and any steps taken to deal with any such issues; and (iii) the audit firm’s internal quality control procedures.

(b)To pre-approve all non-audit services to be provided to the UBS Funds by the independent auditors when, without such pre-approval, the auditors would not be independent of the UBS Funds under applicable federal securities laws, rules or auditing standards.

(c)To pre-approve all non-audit services to be provided by the UBS Funds’ independent auditors to the UBS Funds’ investment advisor or to any entity, that controls, is controlled by or is under common control with the UBS Funds investment advisor (“advisor affiliate”) and that provides ongoing services to the UBS Funds when, without such pre-approval by the Committee, the auditors would not be independent of the UBS Funds under applicable federal securities laws, rules or auditing standards.

(d)   To establish, if deemed necessary or appropriate as an alternative to Committee pre-approval of services to be provided by the independent auditors as required by paragraphs (b) 

and (c) above, policies and procedures to permit such services to be pre-approved by other means, such as by action of a designated member or members of the Committee, subject to subsequent Committee review or oversight.

(e)To consider whether the non-audit services provided by the UBS Funds’  independent auditor to the UBS Funds investment advisor or any advisor affiliate that provides on-going services to the UBS Funds, which services were not pre-approved by the Committee, are compatible with maintaining the auditors’ independence.

Pursuant to Section (d), the Committee has delegated its responsibility to pre-approve the audit and permissible non-audit services required by paragraphs (a), (b) and (c) of Section 4, not exceeding $100,000 (excluding reasonable out-of-pocket expenses) on an annual basis to the Chairperson.  All such pre-approvals will be subject to subsequent Committee review or oversight, including being reported to the full Committee on a quarterly basis at the Committee’s next regularly scheduled meeting after pre-approval.  The Committee may not delegate to management its responsibility to pre-approve services to be performed by the independent auditor.  Requests or applications to provide services that require specific pre-approval by the Committee or the Chairperson will be submitted by both the Fund’s independent auditors and the Fund’s Treasurer or other designated Fund officer and must include a joint statement as to whether, in their view, the request or application is consistent with U.S. Securities and Exchange Commission rules on auditor independence.
