President's letter

February 27, 2023

Dear Shareholder,

In the second half of 2022, markets remained volatile, and investors remained wary. Central banks across the globe continued to combat inflation, leading to increases in interest rates across major markets. After hitting a four decade high of 9.1% annualized in June, total US inflation for the 12 months ending in December dropped to 6.5%. Unlike the first half of the year, inflation moderated, mostly driven by falling energy and food prices and fading supply chain pressures. The US Federal Reserve while still on the quest to reduce inflation, continued to hike interest rates and reduce the size of its balance sheet, although speed of rate hikes moderated.

On the growth front, in the US, while manufacturing retreated according to the Institute for Supply Management (ISM), consumer spending has been resilient, and job and wage growth has been persistently strong. US Treasury Secretary Janet Yellen said recently the economy remains "strong and resilient," and that "you don't have a recession when you have 500,000 jobs added in a month and the lowest unemployment rate in more than 50 years."

US stocks (measured by the S&P 500 Index) toggled in and out of bear market territory throughout 2022, reaching a low point in early October 2022 and recovering somewhat as the year drew to a close. While we saw improvement in the performance of equity markets in the fourth quarter, they still present a challenge to navigate; for instance, the shift in performance and opportunity between value and growth equities. Growth had been dominant for over ten years, but with the high inflation and rising interest rates, performance turned around, and value became resurgent.

Meanwhile fixed income broadly saw extensive repricing in 2022 as rates rose. All longer-term US fixed income assets, including Treasurys, experienced negative returns in 2022, given a sizable shift in US interest rates. Coming into 2023 we see opportunity in fixed income, particularly for active managers, because the higher yields are far more attractive even in the face of potential future rate increases.

These kinds of market shifts and reversals underscore the importance of diversification, particularly in an environment where macroeconomic uncertainty and market volatility continue to run high. As active managers, we aim to take advantage of these challenges and market mis-pricings that may occur along the way to seek value for our clients.

As always, we thank you for being a part of the UBS family of funds.

Sincerely,

Igor Lasun

The markets in review

Economic headwinds increase

The global economy faced several headwinds during the reporting period, leading to expectations for weaker growth and perhaps a recession. In its October 2022 World Economic Outlook Update, the International Monetary Fund ("IMF") lowered its expectation for gross domestic product ("GDP") in 2022, saying, "The global economy is experiencing a number of turbulent challenges. Inflation higher than seen in several decades, tightening financial conditions in most regions, Russia's invasion of Ukraine, and the lingering COVID-19 pandemic all weigh heavily on the outlook. The normalization of monetary and fiscal policies that delivered unprecedented support during the pandemic has dampened demand, as policymakers aim to lower inflation back to target." For 2022, the IMF projects US GDP to grow 1.6% versus 5.7% in 2021, 3.1% in the eurozone versus 5.2% in 2021, 3.6% in the UK compared to 7.4% in 2021, and 1.7% in Japan—unchanged from 2021.

With US inflation hitting a 40-year high in May 2022, the Federal Reserve Board ("the Fed") continued to aggressively raise interest rates over the reporting period. After raising rates three times during the first half of 2022, the Fed hiked rates four additional times over the six months ended December 31, 2022. In total for the year, the Fed raised rates 4.25%, the most since 1980. At the end of 2022, the federal funds rate was in a range between 4.25% and 4.50%, the highest since 2007. Elsewhere, the Bank of England ("BoE") and the European Central Bank ("ECB") raised rates a total of 3.50% and 2.50%, respectively, in 2022. At the end of the year, rates in both regions were the highest since 2008. In contrast, the Bank of Japan (the "BoJ") maintained its loose monetary policy. However, in December 2022, the BoJ raised the target range for its 10-year bond from 0.25% to 0.50%, which could be its first step to ending its accommodative monetary stance. Elsewhere, with inflation remaining elevated in emerging market countries, their central backs also pushed rates higher.

Global equities produce mixed results

Global equities were weak during the third quarter of 2022 against a backdrop of elevated inflation and aggressive monetary policy tightening. The repercussions from the war in Ukraine and several geopolitical issues also weighed on investor sentiment. The market then rallied in the fourth quarter. This was due to several factors, including signs of moderating inflation, hopes that the Fed would be less aggressive in terms of rate hikes in 2023, and that the central bank could orchestrate a "soft landing" for the economy. For the six-months ended December 31, 2022, the S&P 500 Index¹ returned 2.31%, but fell 18.11% in 2022. Outside the US, international developed equities, as measured by the MSCI EAFE Index (net),² gained 6.36% during the reporting period and -14.45% in 2022. Emerging markets equities were weak, as the MSCI Emerging Markets Index (net)³ returned -2.99% during the reporting period and -20.09% in 2022.

The markets in review

The overall fixed income market declines

The overall global fixed income market declined, as most central banks continued to aggressively raise interest rates in an attempt to bring down inflation. In the US, short- and long-term US Treasury yields moved sharply higher. For the six months ended December 31, 2022, the yield on the US 10-year Treasury rose from 2.98% to 3.88%. 10-year government bond yields outside the US also moved higher. (Bond yields and prices tend to move in the opposite direction.) For the six-month reporting period as a whole, the overall US bond market, as measured by the Bloomberg US Aggregate Index,⁴ returned -2.97%. In contrast, riskier fixed income securities generated positive returns. High yield bonds, as measured by the ICE BofAML US High Yield Index,⁵ gained 3.28%. Elsewhere, emerging markets debt, as measured by the J.P. Morgan Emerging Markets Bond Index Global (EMBI Global),⁶ rose 2.93% during the reporting period.

⁴ The Bloomberg 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.

⁵ The ICE BofAML US High Yield Index is an unmanaged index that tracks the performance of US dollar denominated, below investment-grade rated corporate debt publicly issued in the US domestic market.

⁶ 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.

UBS All China Equity Fund

Portfolio performance

For the six months ended December 31, 2022, the UBS All China Equity Fund (the "Fund") returned -15.60%. The Fund's benchmark, the MSCI China All Shares Index (net) (the "Index"), returned -13.41% over the same time period. (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's performance was driven primarily by stock selection decisions.

Portfolio performance summary¹

What worked:

• In terms of stock selection, CSPC Pharmaceutical Group was the top contributor to performance. The company is seeing its traditional drug business stabilize, while its COVID-related mRNA vaccine is on the path to being the first domestically approved vaccine and can potentially enter a multibillion dollar market space.

• Several other stock selection decisions benefited performance during the reporting period.

– Shares of Ping An Insurance rallied after the Chinese government announced easing of COVID restrictions and more concrete support measures to support the property sector. This would enable more face-to-face meetings with customers. The stock had been overly penalized on its risk exposure to the property market.

– Shares of SSY Group outperformed as investor sentiment improved on expectations that price pressures from its centralized procurement negotiations may be easing. The company expects to see growing revenue from its bulk pharmaceuticals business and approval for multiple products from the National Medical Products Administration.

– Anhui Gujing Distillery was additive for performance. The company is expected to execute better on its sales and marketing with the introduction of an incentive program. This would translate into better longer-term revenues. Towards the end of the year, the Chinese government announced easing of COVID restrictions, which should drive a rebound in consumer spending, including social gatherings and dining in and, therefore, improve demand.

– Our decision to underweight Alibaba contributed to relative performance. Alibaba faces continued regulatory concerns and weaker performance due to COVID lockdowns during much of the reporting period.

What didn't work:

• Certain stock selection decisions detracted from performance during the six-month period.

– The Fund's investment in Yunnan Energy New Material negatively impacted returns. Its shares fell after news that its two founders were under 'residential surveillance' and an investigation related to their supply of materials to the tobacco industry. Though the tobacco industry is a small part of its business, this development weighed on market sentiment. We are monitoring the stock.

– Shares of NetEase detracted from performance despite its recent rally given to the pivot of the country's zero-COVID policy. For the reporting period as a whole, shares of NetEase were down due to previous expectations that the weak economy caused by lockdowns may impact its revenue growth as gaming spending is more of a discretionary item. We continue to hold the stock.

– Shares of Hangzhou Silan fell due to investor concerns about the spillover effect of the weakness in the electronics space and low consumer demand. We continue to hold the stock.

¹ For a detailed commentary on the market environment in general during the reporting period, see page 2.

UBS All China Equity Fund

– Shares of Country Garden Services underperformed during the reporting period despite the recent rally brought about by more supportive measures for the real estate sector. The company had been acquiring other property management companies and assets and investors were concerned if those could be successfully integrated. There were also concerns whether the company's affiliate, Country Garden Holdings, might face debt distress. We continue to hold the stock.

– Shares of Jinke Smart Services declined during the reporting period, as the company posted disappointing results and potentially will have to increase impairment provision from its parent company Jinke Property. As a result, we sold our position in the company.

Portfolio highlights

• Tencent is the leading company in China's PC/mobile internet market, and provides services such as instant messaging, online gaming, social community, news and online music. Tencent has established several powerful online service platforms and accumulated a huge number of loyal customers. With its current strong position, we expect the company to ride on the mature business models and consistently grow its business going forward. Fast-growing online games—along with newly emerging mobile games, which is one of the largest revenue-generating segments—will likely contribute most to the company going forward.

• Kweichow Moutai engages in the manufacture and distribution of Moutai liquor series products. Moutai is a Chinese premium liquor brand with strong pricing power and growth visibility. The share price is attractively valued, and the company offers the potential to benefit from state-owned enterprise (SOE) reform.

• China Merchants Bank has the leading retail banking franchise in China. This was built up over many years due to an early focus on the segment, while large state-owned enterprise banks were focusing on corporations. We believe China Merchants Bank is well-positioned to benefit from China's growing wealth, which would drive demand for wealth management products and financial advice.

• NetEase is a leading online game company in China. It has a good track record for delivering blockbuster games, and has posted healthy growth for more than 10 years. We believe that NetEase continues to have a strong game pipeline and will be able to deliver new revenue streams. We believe the company is well-positioned as a leading player in China's online entertainment sectors, particularly online games and music.

• Alibaba is a large e-commerce company. We believe that e-commerce penetration will continue to grow in China, even in the midst of a retail slowdown. Thus, we consider it a more defensive part of retail sales, and we believe Alibaba has the strongest position in China's e-commerce space.

• The Fund did not invest in derivatives during the reporting period.

The Trust, with respect to the Fund, and UBS Asset Management (Americas) Inc., the Fund's investment advisor and administrator ("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, such as proxy-related 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 28, 2023, do not exceed 1.10% for Class P shares. The Advisor has also entered into a written agreement pursuant to which the Advisor has agreed to waive a portion of its management fees and retained administration fees, and/or to reimburse expenses (excluding expenses incurred through investment in other investment companies, interest, taxes, brokerage commissions and extraordinary expenses, such as proxy-related 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, such as proxy related expenses), through the period ending October 28, 2023, do not exceed 0.30% for Class P2 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 fiscal years following the date on 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 the lesser of any applicable expense limit that is in place for the Fund (i) at the time of the waiver or reimbursement or (ii) at the time of the recoupment. 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.

² Inception date of Class P2 is April 21, 2022.

³ Class P and Class P2 shares do not bear initial or contingent deferred sales charges or ongoing 12b-1 service and distribution fees, but Class P and Class P2 shares held through advisory programs may be subject to a program fee, which, if included, would have reduced performance.

UBS Dynamic Alpha Fund

Portfolio performance

For the six months ended December 31, 2022 (the "reporting period"), Class A shares of UBS Dynamic Alpha Fund (the "Fund`") returned 0.65% (Class A shares returned -4.96% after the deduction of the maximum sales charge), while Class P shares returned 0.91%. For purposes of comparison, the ICE BofA US Treasury 1-5 Year Index returned -1.35% during the same time period, the MSCI World Index (net) returned 2.97%, and the FTSE One-Month US Treasury Bill Index returned 1.36%. (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 12; (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.)

Overall, the Fund delivered positive absolute returns in a challenging market environment of highly volatile but, on average, flat equity markets and rising yields. The strategy was in-line with its cash plus objective over the reporting period.

Portfolio performance summary¹

• The portfolio's strategic allocation to equities was additive, while fixed income detracted from performance.

– Our strategic allocation to global equities delivered marginally positive returns over the reporting period, with steep to moderate drawdowns during summer and a recovery during the fourth quarter of 2022. In terms of the latter, falling inflation expectations and hopes for less aggressive monetary tightening drove the market higher.

– Fixed income was a slight detractor overall as yields rose over the reporting period. An exception was high-yield corporate bonds, which were additive for returns due to narrowing credit spreads.

• Overall, market allocation decisions contributed to results.

– We maintained an equity underweight for most of the reporting period to limit portfolio drawdowns. Over the six months ended December 31, 2022, this decision slightly detracted from performance as the underweight was more pronounced during the fourth quarter of the year when equities rallied.

– Within equities, we assumed a pro-cyclical value position for most of the reporting period, with the rationale of further earnings upside from a reopening of the global economy. Most of the trades within this category contributed significantly to performance, such as long Stoxx600 Banks versus Eurostoxx50, long FTSE MIB Italy versus Stoxx50 and long MSCI World Value versus the market positions.

– Trades that detracted from performance were more defensively minded, such as a long UK versus EuroStoxx50 position and a long Topix versus MSCI World trade, the latter of which performed well during the prior reporting period, but was pressured by a sharp rise in the Japanese yen towards the end of the year.

• Overall, active currency positions contributed to results.

– The largest contributor to performance was a short Great Britain pound versus euro trade, which benefited from ongoing headwinds to pan-European growth expectations. Both currencies were supported by hawkish central banks, but weaker growth in the UK and the more pro-cyclical tilt of the Great Britain pound caused it to underperform. Other positive trades were the long Brazilian real versus the US dollar, and a long Mexican peso versus the US dollar. These trades benefited from increasing yield differentials and the expectation of a Chinese reopening supporting emerging market currencies. Slight detractors were a long Japanese yen versus US dollar and short New Zealand dollar versus US dollar positions. We used derivatives, specifically futures and forwards, for risk management purposes and as a tool to help enhance returns across various strategies. Derivatives were just one tool, among others, that we used to implement our market allocation strategy. The use of derivatives contributed to Fund performance.

The annualized gross and net expense ratios, respectively, for each class of shares as in the October 28, 2022 prospectuses were as follows: Class A—2.33% and 1.37%; Class P—2.11% and 1.12%. 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 and administrator ("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, dividend expense and security loan fees for securities sold short, and extraordinary expenses, such as proxy-related expenses), through the period ending October 28, 2023, do not exceed 1.35% for Class A shares and 1.10% 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 fiscal years following the date on 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 the lesser of any applicable expense limit that is in place for the Fund (i) at the time of the waiver or reimbursement or (ii) at the time of the recoupment. 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 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.

³ The ICE BofA US Treasury 1-5 Year Index is an unmanaged index designed to track US Treasury securities with maturities between 1 and 5 years. Investors should note that indices do not reflect the deduction of fees and expenses.

⁴ The MSCI World Index (net) is a free float-adjusted market capitalization weighted index that is designed to measure the equity market performance of developed 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 FTSE One-Month US Treasury Bill Index is an unmanaged index representing monthly return equivalents of yield averages of the last one month Treasury Bill issue. Investors should note that indices do not reflect the deduction of fees and expenses.

UBS Global Allocation Fund

Portfolio performance

For the six months ended December 31, 2022 (the "reporting period"), Class A shares of UBS Global Allocation Fund (the "Fund") returned -0.68% (Class A shares returned -6.14% after the deduction of the maximum sales charge), while Class P shares returned -0.66%. For comparison purposes, the Fund's benchmark, MSCI All Country World Index (net) returned 2.28% and the FTSE World Government Bond Index (hedged in USD), a secondary benchmark returned -4.16%. In contrast, the Fund's secondary benchmark, the 60% MSCI All Country World Index (net)/40% FTSE World Government Bond Index (hedged in USD), returned -0.18% during 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 23; 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 negative total return during the reporting period. Both tactical asset allocation and security selection detracted from performance.

During the review period, we used derivatives for risk management purposes and as a tool to help enhance returns in the portfolio. We used a variety of equity and fixed income options, futures and swaps to implement our tactical asset allocation strategy.

Portfolio performance summary

• Bottom-up security selection detracted from performance.

– US Large-Cap Value and International Equity strategies contributed to performance. This was offset by the negative impact from Emerging Markets Equity Opportunity and US Large Cap Growth strategies.

• Active asset allocation decisions detracted from performance.

– Overall, tactical asset allocation in equities detracted from returns, while fixed income and currency decisions contributed to results.

– Within equities, the largest detractor was an overweight to Brazil over emerging market equities due to fiscal risk with the new Brazilin President Lula da Silva. In addition, an overweight to Chinese equities detracted from returns due to the country's economic slowdown from stringent COVID-19 measures. However, an overweight to energy over world equities contributed to returns on the news of China's reopening, along with supply constraints driving energy prices higher.

– Within currency, long positions in the Japanese yen and Mexican peso versus the US dollar contributed to returns. In addition, a short position in more cyclical Asian currencies contributed to returns.

– Within fixed income, a broad duration underweight contributed to returns over the reporting period. In addition, an overweight to German bunds over UK gilts contributed to performance, as investors focused on rising central bank rate hikes and inflation, in addition to the UK's economic outlook.

The annualized gross and net expense ratios, respectively, for each class of shares as in the October 28, 2022 prospectuses were as follows: Class A—1.48% and 1.29%; Class P—1.20% and 1.04%. 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 and administrator ("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, such as proxy-related expenses), through the period ending October 28, 2023, do not exceed 1.20% for Class A shares and 0.95% 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 fiscal years following the date on 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 the lesser of any applicable expense limit that is in place for the Fund (i) at the time of the waiver or reimbursement or (ii) at the time of the recoupment. 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.

³ 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.

⁴ The FTSE 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.

⁵ The 60% MSCI All Country World Index (net)/40% FTSE 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.

* Non-income producing security.

^† Amount represents less than 0.05% or (0.05)%.

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. Securities exempt from registration pursuant to Rule 144A, in the amount of $5,008,728, represented 2.8% of the Fund's net assets at period end.

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

³ The table below details the Fund's investment in a fund advised by the same Advisor as the Fund. The Fund does not pay advisory fees that are retained by the Advisor in connection with its investment in other investment companies advised by the Advisor, but may pay other expenses associated with such investments (such as sub-advisory fees paid to other parties, if any).

⁴ In U.S. dollars unless otherwise indicated.

⁵ Variable or floating rate security. The interest rate shown is the rate in effect as of period end and changes periodically.

⁶ Variable or floating rate security for which the interest rate adjusts periodically based on changes in current interest rates and prepayments on the underlying pool of assets. Rate shown is the rate in effect as of period end.

⁷ Step bond—coupon rate increases in increments to maturity. The rate disclosed is the rate at the period end; the maturity date disclosed is the ultimate maturity date.

⁸ 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.

⁹ 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.

¹⁰ Rates shown reflect yield at December 31, 2022.

¹¹ Payments made or received are based on the notional amount.

¹² 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.

UBS Emerging Markets Equity Opportunity Fund

Portfolio performance

For the six months ended December 31, 2022, Class P2 shares of UBS Emerging Markets Equity Opportunity Fund (the "Fund") returned -3.63%, while Class P shares returned -4.03%. The Fund's benchmark, the MSCI Emerging Markets Index (net) (the "Index"), returned -2.99%. 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 negative return and underperformed its benchmark during the reporting period.

Portfolio performance summary¹

What worked:

• On a sector level, stock selection in consumer discretionary, financials and energy were key contributors.

• On a stock level, our overweight in Bank Mandiri (Indonesia, financials) and MercadoLibre (Brazil, consumer discretionary) were among the top contributors to performance over the reporting period. Bank Mandiri outperformed as Indonesia stands to benefit from the rise in commodity prices and as investors looked toward the country's reopening. Catalysts for the sector include consistent low cost of funds, non-performing loans/provision staying within range of guidance, a small but promising pick-up in credit demand, and limited impact of Federal Reserve taper on system liquidity. MercadoLibre outperformed on better than expected quarterly results. Margin improvement was better than expected.

What didn't work:

• On a sector level, stock selection within information technology, real estate and consumer staples detracted from performance.

• On a stock level, overweights in LONGi (China, information technology) and Country Garden Services (China, real estate) were among the main headwinds for results over the reporting period. LONGi's underperformance followed a drop in prices of polysilicon, wafer, cell and module, due to market concerns of more downside ahead, driven by new supply. The first quarter is usually a weak season for solar panel installation and prices across the supply chain would typically see downward pressure due to low shipments. Looking ahead, we believe that lower module prices could boost installation demand. For Country Garden Services (CGS), despite the recent rally brought about by more supportive measures for the real estate sector, the company still ended the reporting period posting a negative return due to weak sentiments towards the real estate industry could boost installation demand and we continue to own the stock. CGS had been acquiring other property management companies and assets and investors were concerned if those could be successfully integrated. There were also concerns whether CGS' affiliate, Country Garden Holdings, might face debt distress. We have since exited from the stock.

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 and administrator ("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, such as proxy-related expenses), through the period ending October 28, 2023, do not exceed 1.00% for Class P shares and 0.40% for Class P2 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 fiscal years following the date on 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 the lesser of any applicable expense limit that is in place for the Fund (i) at the time of the waiver or reimbursement or (ii) at the time of the recoupment. 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.

Investors should note that indices do not reflect the deduction of fees and expenses.

UBS Engage For Impact Fund

Portfolio performance

For the six months ended December 31, 2022, Class P shares of UBS Engage For Impact Fund (the "Fund") returned 4.60%, while the Class P2 shares returned 4.89%. The Fund's benchmark, the MSCI All Country World Index (net) (the "Index"), returned 2.28% over the same time period. (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's performance was driven primarily by stock selection.

Portfolio performance summary¹

What worked:

• Stock selection within the financials and information technology sectors contributed to performance during the reporting period.

• Several individual stock positions were positive for performance, with the largest contributors being:

– AIB Group's share price recorded positive performance as investors expect interest rates to stay higher for longer. In addition, the market recognized the resilience of the Irish economy as it performed well relative to Europe. The concentration of the Irish banking market allows AIB Group to improve its return on equity (ROE).

– Ingersoll Rand performed well over the period as the company posted revenues and adjusted earnings before interest, taxes, depreciation, and amortization (EBIDTA) ahead of expectations and slightly raised guidance, supported by demand which continues to be robust.

– Bank Mandiri's share price benefited from recent interest rate hikes and a relatively cleaned up cost of funds. Overall, the company has shown strong loan growth in retail, as well as investment loans, highlighting the strength of the post-COVID recovery in Indonesia.

– Genmab's shares traded up following the advancement of a key pipeline drug with submission for US Food & Drug Administration (FDA) approval.

– Erste Group Bank's share price increased on the back of solid earnings, showing confidence in their 2024 target, lower cost-to-income ratio, and 20% net interest income (NII) growth in 2022. Also, fears in early 2022 that the Russia-Ukraine conflict would spill over into Erste's markets has not materialized yet. In general, banks' share prices adjusted for expectations of interest rates staying higher for longer.

What didn't work:

• Stock selection in the health care and consumer staples sectors were the largest detractors from performance during the period. The largest individual detractors were:

– Mowi's shares fell following the announcement that the Norwegian parliament would review a proposed 40% resource tax on salmon and trout farming in the country, which could impact the company's profitability in the future. The proposal is currently out for consultation and historically, we have typically seen such taxes come in much smaller in the end. To weigh in on the argument, Mowi and its other two major peers announced in early October 2022 the cancellation of their biomass growth purchases. We eliminated the position during the reporting period.

¹ For a detailed commentary on the market environment in general during the reporting period, page 2.

UBS Engage For Impact Fund

– China Mengniu Dairy's shares were weighed down by its results showing a year-over-year decline in adjusted net profit, despite strong growth in core product categories. We maintain our position in the stock.

– Digital Realty Trust detracted from performance as rising interest rates dampened data infrastructure demand and guidance was trimmed on foreign currency headwinds. We maintain our position in the stock.

– Maravai LifeSciences Holdings shares detracted from returns after results revealed a decline in revenue versus the previous year. Management guided down fiscal year 2022 revenue due to a slowdown in the uptake for boosters within the CleanCap segment and concerns over weakness in China. We eliminated the position during the reporting period.

– Trimble's share price decreased after it announced the planned acquisition of Transporeon, a transport logistic firm for €1.88 billion. In the current environment, investors are wary of companies raising debt and skeptical of Trimble's ability to de-lever in less than two years. We maintain our position in the stock.

The Fund did not use derivatives during the reporting period.

Portfolio highlights

The UBS Engage For Impact Fund is a high conviction, impactful portfolio invested in companies that we believe have an important role to play in achieving the United Nations Sustainable Development Goals (SDGs)—not just through the products and services they sell, but also through improvements in their operations and supply chains. The portfolio invests across five impact themes aligned with the SDGs, which are Climate, Health, Food, Water and Empowerment.

As of December 31, 2022, the portfolio's largest exposure was to SDG 3—Good Health and Well-being (22%), SDG 7—Affordability and Clean Energy (18%), and SDG 2—Zero Hunger (15%).

The Fund's top three overweights and their impact case as of December 31, 2022 were:

Ingersoll Rand

Impact Theme: Climate

Product Impact: SDG 3 (Good Health and Well-being) and 12 (Responsible Consumption and Production)

Ingersoll Rand is a diversified industrial machinery company involved in industrial technologies & services (mission-critical flow creation, such as compression, blowers, vacuums, pumps, etc) and precision & science tech (medical applications). The company has eliminated its exposure to the upstream oil and gas industry. An important growth driver for Ingersoll Rand is its push into medical end markets, where they manufacture a broad range of highly specialized gas, liquid and precision syringe pumps and compressors that are specified by medical and lab equipment suppliers and integrated into their equipment for final use (oxygen therapy, blood dialysis, patient monitoring, lab sterilization and wound treatment). We have had a very constructive dialogue over the years as the company reshaped its portfolio of assets, practices and approach to sustainability. We continue to engage with the business to set more ambitious sustainability goals, especially as it relates to climate (in line with SDG 12 and 13).

UBS Engage For Impact Fund

Spectris

Impact Theme: Climate

Product Impact: SDG 12 (Responsible Consumption and Production)

Spectris is a leader in niche markets in precision instruments, test & measurement, control and process technology, enabling efficiencies in production processes, saving energy, water, molecules and food across a variety of manufacturing applications, from semiconductors to biopharma. Our engagement focused on encouraging the company to set diversity targets, in support of SDG 5 and 10 (targets 5.5 and 10.2, 10.3 and 10.4). The company is working on a three-year diversity and inclusion plan supported by an external consultant. The plan draws from best practices identified in the US, with Spectris' Omega division leaders having been active supporters of Pride and Black History Months, and organizing events to celebrate cultural differences, which is reflected in employees' diversity at all seniority levels. Their primary objective is that employees feel safe and supported regardless of their race and gender, and this goal is being assessed by Spectris's first group-wide employee survey. For now, the company has not set objectives in terms of recruitment, promotion and representation of minorities and genders.

Danone

Impact Theme: Food

Product Impact: SDG 2 (Zero Hunger)

Danone is the smallest of the three large European food and beverage companies and has a leading position in plant-based products, as well as attractive specialist nutrition businesses. The company currently estimates that 90% of its sales by volume is derived from healthy products, and Danone is among the three top-performing companies according to the Global Access to Nutrition Index. With management renewal, the recently announced organic transformation plan will likely drive improvements at the company through a simplification and delayering of the organization, by giving local management more control, and by breaking down silos between categories. Our engagement focus on encouraging this industry leader to raise the bar in terms of nutrition, product transparency and marketing to influence its competitors, in support of SDG 2, zero hunger, target 2.2 and SDG 17 on partnership for the goals. This is in collaboration with other investors, as part of the Healthy Markets Coalition.

The Trust, with respect to the Fund, and UBS Asset Management (Americas) Inc., the Fund's investment advisor and administrator ("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, such as proxy-related expenses), through the period ending October 28, 2023, do not exceed 0.85% for Class P shares and 0.25% for Class P2 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 fiscal years following the date on 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 the lesser of any applicable expense limit that is in place for the Fund (i) at the time of the waiver or reimbursement or (ii) at the time of the recoupment. 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.

UBS International Sustainable Equity Fund

Portfolio performance

For the six months ended December 31, 2022, Class A shares of UBS International Sustainable Equity Fund (the "Fund") returned 3.84% (Class A shares returned -1.87% after the deduction of the maximum sales charge), while Class P shares returned 4.02% and Class P2 shares returned 4.38%. The Fund's benchmark, MSCI ACWI ex-US Index (the "Index"), returned 2.96%. (Class P2 shares have lower expenses than the other share classes in the series. Returns for all share classes over various time periods are shown on page 50; 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's performance was due primarily to stock selection.

Portfolio performance summary¹

What worked:

• Stock selection in the financials and energy sectors added the most value relative to the benchmark.

• Several individual stock positions were positive for performance during the six-month period. The largest contributors were:

– SLB (previously known as Schlumberger) was the top contributor over the period on the back of commodity prices which continue to be elevated.

– Metso Outotec's shares continued to trade well on the back of recent earnings which demonstrated strong operational performance with a full order book, acceleration in sales growth, and adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) margins that rose year-over-year.

– Shares of Axis Bank rose as earnings were better than expected, driven by sharply falling credit costs and strong year-over-year core operating profit growth.

– In spite of supply chain constraints, inflation, and broad economic uncertainty, Ashtead Group delivered strong revenues which were up from the previous year and ahead of consensus. In addition, operating profit exceeded previous expectations. The company increased its guidance for group rental growth on the back of signs of momentum in end markets which remain supportive.

What didn't work:

• Stock selection in the consumer discretionary and consumer staples sectors detracted the most relative to the benchmark. The largest individual detractors were:

– Ubisoft Entertainment was the main detractor as its shares sharply declined following the announcement that Tencent increased its ownership indirectly through an agreement with the founders. This was interpreted by investors as decreasing the likelihood that the company would be acquired in the near term. While Tencent's partnership with Ubisoft Entertainment supports the deployment of new games on mobile devices, especially in China, there were concerns over how this deal could benefit all shareholders. We maintain our position in the stock.

¹ For a detailed commentary on the market environment in general during the reporting period, page 2.

UBS International Sustainable Equity Fund

– Li Auto posted disappointing guidance and a decline in revenues. Chinese stocks were hit by COVID lockdowns and supply chain bottlenecks, dampening their earnings outlook. However, we believe that the longer-term secular trends shaping the electric vehicle (EV) market remain intact, which should benefit companies like Li Auto. We maintain our position in the stock.

– Barry Callebaut's shares lagged the broader market as the company expects a weaker first quarter 2023 due to a combination of challenging comparisons, destocking by their customers, and some disruptions at one of their large factories. We maintain our position in the stock.

– Koninklijke Philips detracted from returns as supply chain and inflationary headwinds limited near term margins and the Dreamstation recall issues persisted. We maintain our position in the stock.

The Fund did not have any exposure to derivatives during the reporting period.

Portfolio highlights

Our investment philosophy combines our bottom-up fundamental research with rigorous sustainability analysis. We look for companies that are attractively valued and integrate sustainability factors into their business models to build a competitive advantage.

The investment process for the International Sustainable Equity strategy is driven by a combination of fundamental, ESG (Environmental, Social and Governance) and thematic factors. Through this process, we aim to identify our best investment ideas across sectors and geographies from a stock-specific standpoint.

Please see below for summaries on the top three active weights in the portfolio, as of December 31, 2022:

Galp Energia

We believe Galp Energia is the best managed integrated major energy company in Europe with a high quality portfolio of high return assets, made of upstream energy (70% of 2020 revenues) and downstream activities (28%). While Galp Energia is involved in carbon intensive activities, it is one of the most efficient players, with 9.9 kg CO2e/boe (kilograms of carbon dioxide equivalent) for its upstream assets in comparison to 18.8 kgCO2e/boe for the industry average. The company embraces the energy transition with plans to direct half of its capital expenditures to low carbon projects and 30% towards renewables by 2025, limiting upstream spending. The company aims to reduce absolute greenhouse gas emissions from operations by 40% by 2030 (versus its 2017 level) and become net carbon neutral by 2050. This includes a large project to improve its Sines refinery hub in terms of energy efficiency (halve operation emissions by 2030) and allow crude sourcing flexibility and adapt for biofuels production. In terms of energy assets, in 2030 the company will have 12GW of renewable operating capacity. Finally, Galp Energia is building exposure to green hydrogen, with a first plan for 100Mw capacity by 2025.

UBS International Sustainable Equity Fund

SLB

SLB is an offshore drilling company that also provides technology for reservoir characterization, drilling, production and processing to the oil and gas industry—including software and seismic technology, integrated asset performance solutions, and reservoir productivity and performance optimization tools. The company's ESG profile appears better than its energy services peers, highlighted by industry-leading commitments (including scope 1, 2, and 3 net zero by 2050), sustainable development goals (SDG) alignment (11/17), and business strategy with new energy focus. In the short-term, SLB sees momentum in driving customer emissions' reduction efforts while, in the medium- to longer-term, a New Energy unit that is already in investing mode across numerous technologies, products, and geographies. We think the advantage for global services companies with scale is the reach into many assets of industry throughout the world (SLB operates in roughly 120 nations), with few better situated than SLB—already leveraging expertise in carbon capture and storage (CCS) (60 projects globally) and geothermal (participating in 70% of all such projects globally), but also participating in hydrogen and lithium projects. SLB has long-standing efforts in low carbon solutions and provides the platform to build out new business models driven by less carbon-intensive digital offerings and transition growth. Its focus on technology supports relatively low emission intensity compared to peers. Lastly, the company has strong disclosure on social engagements, diverse hiring, and health & safety and added a Chief Strategy & Sustainability Officer in 2021.

Barry Callebaut

Barry Callebaut is the world's leading manufacturer of high-quality chocolate and cocoa products and has been dedicated to this business for more than 150 years. The company operates out of more than 40 countries, runs about 60 production facilities, employs a global workforce of more than 12,000 people, and generates annual sales of about 6.9 billion Swiss francs (approximately $7.1 billion). We see long-term structural growth coming from outsourcing and volume growth, complemented by margin growth through leverage. The company is globally diversified, which gives them a competitive edge over smaller local players and allows for more capacity in innovation. We believe Barry Callebaut has a strong management team that is focused on long term margin expansion and top line growth with sustainability embedded in the corporate culture DNA. While the shutdown of restaurants/hotels has created short term headwinds for their Gourmet segment, we believe post crisis will be an opportunity to gain market share with a solid pipeline in food manufacturing. Overall, we view Barry Callebaut as being a recovery winner post-lockdown. In 2016, the company launched Forever Chocolate, with a plan to make sustainable chocolate the norm by 2025 and drive a sustainable cocoa and chocolate supply chain. It aims to have more than 500,000 cocoa farmers lifted out of poverty and have 100% sustainable ingredients in all their products. In its fourth annual progress report, Barry Callebaut reported 143,233 cocoa farmers in their supply chain are out of poverty and also reported a 8.1% reduction in their carbon footprint.

The annualized gross and net expense ratios, respectively, for each class of shares as in the October 28, 2022 prospectuses were as follows: Class A—1.37% and 1.25%; Class P—1.11% and 1.00%; Class P2—1.12% and 0.25%. 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 and administrator ("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, such as proxy-related 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, such as proxy-related expenses) do not exceed 1.25% for Class A shares, 1.00% for Class P shares. This fee waiver and expense arrangement may only be amended or terminated by shareholders. The Advisor has also 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, such as proxy-related 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, such as proxy-related expenses), through the period ending October 28, 2023, does not exceed 0.25% for Class P2 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 fiscal years following the date on 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 the lesser of any applicable expense limit that is in place for the Fund (i) at the time of the waiver or reimbursement or (ii) at the time of the recoupment. 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.

³ The MSCI ACWI ex USA Index captures large and mid cap representation across 22 of 23 Developed Markets (DM) countries (excluding the US) and 25 Emerging Markets (EM) countries*. With 2,336 constituents, the index covers approximately 85% of the global equity opportunity set outside the US.

⁴ Inception date of Class P2 of UBS International Sustainable Equity Fund is October 30, 2020.

The Fund's investment goal is to maximize total return, consisting of capital appreciation by focusing on fundamentally attractive dividend-paying stocks.

Portfolio performance summary¹

What worked:

• In terms of stock selection, holdings in the information technology and consumer discretionary sectors were most additive to performance relative to the S&P 500.

• In terms of sector allocation, the portfolio's underweight to the communication services sector and overweight to energy were the largest contributors to relative performance.

• A number of individual holdings were beneficial for absolute performance, including:

– Energy stocks such as Phillips 66 and EOG Resources were among the strongest performers given tight oil markets and energy sector outperformance. Phillips 66's diversified business model across refining, chemicals, midstream, and marketing helps provide earnings stability through the cycle. Rebuilding of refined product inventories and shortage of global refining capacity should support elevated margins. EOG Resources is a high-quality, low-cost exploration and production company, with a strong track record of consistent execution and top-tier returns.

– Shares of Starbucks rallied following a positive September 2022 Investor Day, where the company outlined its reinvention plan aimed to improve both partner and customer experiences. The company expects to drive 10-12% annualized sales growth and margin expansion over the next three years. Additionally, Starbucks' shares benefited from continued strength in US store sales and prospects of economic reopening in its largest growth market, China.

What didn't work:

• Stock selection within the industrials sector detracted most from relative performance.

• In terms of sector allocation, no sectors detracted from relative performance.

• Several individual fund holdings weighed on absolute performance, including:

– Microsoft's stock faltered on decelerating growth in its cloud business, Azure, and concerns of a weakening enterprise spending environment amid an economic slowdown. While the operating environment has proven challenging, we remain constructive on the long-term outlook for the company. Microsoft remains one of the dominant cloud service providers, in a market that remains underpenetrated. In additional, Microsoft's Windows and Office 365 platforms remain consumer and corporate staples. We continue to hold the stock.

UBS US Dividend Ruler Fund

– Shares of super-regional bank Truist Financial underperformed. Higher investments and delays in cost savings from the company's merger of equals (between SunTrust and BB&T) overshadowed higher net interest income and a pickup in loan growth. We continue to hold the stock.

– Comcast's shares declined given lowered expectations for broadband subscriber growth and increasing competition from telecom providers. We removed Comcast from the portfolio in September 2022.

The Fund did not invest in derivatives during the reporting period.

UBS US Quality Growth At Reasonable Price Fund

Portfolio performance

For the six months ended December 31, 2022 (the "reporting period"), Class P shares of UBS US Quality Growth At Reasonable Price Fund (the "Fund") returned -0.12%. For comparison purposes, the Russell 1000 Growth Index (the "Index") returned -1.48%. 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.

Fund overview

The Fund's investment goal is to provide capital appreciation by seeking exposure to attractively valued, high quality growth stocks.

Portfolio performance summary¹

What worked:

• Stock selection within the consumer discretionary and energy sectors was a meaningful contributor to performance relative to the Russell 1000 Growth Index.

• Within sectors, our overweight allocation to health care was a modest contributor to performance.

• A number of individual holdings were beneficial for absolute performance, including:

– Amidst a worsening economic environment with still elevated inflation, shares of TJX Companies outperformed as consumers traded down to off-price retailers. Elevated inventory at traditional retailers presented a strong buying environment for TJX Companies. Moreover, its pricing initiative helped drive a recovery in margins.

– We added SLB (previously known as Schlumberger) to the portfolio in late July 2022 (and subsequently increased our position in September) on the thesis that the underinvestment in oil supplies over the past few years should drive "higher for longer" oil prices and ultimately a pickup in international drilling and development activity. Third quarter 2022 results for the company topped consensus expectations, with quarterly earnings per share and pretax operating margins reaching seven-year highs.

– Intuitive Surgical shares rallied on better-than-expected DaVinci systems shipments and healthy 20% procedure volume growth in its third quarter earnings results.

What didn't work:

• Stock selection in the information technology sector was a notable detractor from relative performance.

• In terms of sector allocation, our overweight to communication services modestly detracted from performance.

• Several individual holdings weighed on absolute performance, including:

– Alphabet's shares fell on decelerating revenue growth in its core Search and YouTube businesses. While not immune to a cyclical slowdown in global advertising spending, Alphabet shares ended 2022 trading at 17 times consensus 2023 earnings estimates — a 20% discount to the Russell 1000 Growth Index. Longer-term, we view Alphabet as a leader in digital advertising, as well as global cloud infrastructure. We continue to hold the stock.

¹ For a detailed commentary on the market environment in general during the reporting period, page 2.

UBS US Quality Growth At Reasonable Price Fund

– Amazon.com's shares declined due to fears of consumer weakness, decelerating growth in its AWS cloud business, and higher-than-expected costs (shipping, labor, warehousing) weighing on quarterly earnings results and forward-looking guidance. While these issues may linger in the near-term, we remain positive on the company's long-term prospects. Amazon.com has more recently decided to rein in investments in new capacity and appears poised to deliver improved profitability. Amazon.com remains the market leader in e-commerce and cloud computing — two significant secular growth drivers. We continue to hold the stock.

– Microsoft's stock faltered on decelerating growth in its cloud business, Azure, and concerns of a weakening enterprise spending environment amid an economic slowdown. While the operating environment has proven challenging, we remain constructive on the long-term outlook for the company. Microsoft remains one of the dominant cloud service providers, in a market that remains underpenetrated. In additional, Microsoft's Windows and Office 365 platforms remain dominant in their categories and essentials for both consumers and businesses. We continue to hold the stock.

The Fund did not invest in derivatives during the reporting period.

UBS U.S. Small Cap Growth Fund

Portfolio performance

For the six months ended December 31, 2022, Class A shares of UBS U.S. Small Cap Growth Fund (the "Fund") returned 4.49% (Class A shares returned -1.25% after the deduction of the maximum sales charge), while Class P shares returned 4.62%. The Fund's benchmark, the Russell 2000 Growth Index (the "Index"), returned 4.38% 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 70; 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's performance was driven primarily by stock selection decisions.

Portfolio performance summary¹

What worked:

• Within stock selection, Shift4 Payments was the top contributor to performance.

– Shift4 Payments is a provider of integrated payment processing and technology solutions for merchants. The stock rallied on investor optimism regarding the outlook for the company to continue to shift gateway customers to end-to-end payment agreements, as well as the company's diversification of customer segments away from restaurants and hospitality to other areas, including sports, events, and travel.

• Several other stock selection decisions benefited performance.

– Performance Food Group is a leading distributor of food and related products. The stock rose on continued investor enthusiasm that the company's planned sales force expansion should translate into new accounts and increased sales over the next several quarters.

– Medpace is a full-service clinical research organization that serves numerous therapeutic and specialty areas. The company's shares surged higher after reporting quarterly results and providing initial guidance for 2023 that exceeded consensus estimates.

– Lattice Semiconductor designs, develops, and markets programmable logic devices. The stock rallied strongly after posting strong quarterly results and raising its guidance for the fourth quarter of 2022. The company also launched Avant, a new platform of midrange Field-Programmable Gate Arrays (FPGAs), in early December. The new product offering is expected to drive material addressable market expansion for the company.

– Herc is an equipment rental company to a variety of industrial markets. After several months of underperformance, the stock rose on sentiment that the company will benefit from declining interest rates.

• Within sector allocation,the Fund's underweight positions in communications services and utilities contributed to returns over the reporting period.

What didn't work:

• Certain stock selection decisions detracted from the Fund's returns during the reporting period.

– R1 RCM operates a revenue cycle management company for healthcare providers. The company reported disappointing third quarter 2022 results and provided guidance for 2023 that was below consensus expectations. This was due in part to elongated payment cycles and slower than expected customer integrations. Furthermore, at that time the company announced that the Chief Executive Officer would be stepping down at the end of 2022. We continue to own the stock.

– Chart Industries is a leading provider of technology, equipment and services related to liquefied natural gas (LNG), hydrogen, biogas, and carbon dioxide capture amongst other applications. The stock declined sharply following the company's announcement that it is acquiring Howden Group for $4.4 billon. The transaction will increase the company's debt levels and is expected to close in the first half of 2023. We continue to own the stock.

– DigitalOcean is a cloud computing platform offering on-demand infrastructure and platform tools for developers, start-ups, and small and medium-sized businesses. The stock underperformed as investors rotated out of year-to-date winners and higher multiple software stocks. We continue to own the stock.

– Azenta provides life sciences solutions including cold-chain sample management solutions and genomic services across areas such as drug development, clinical research, and advanced cell therapies. The company reported quarterly results that were below expectations. This was due in part to foreign exchange headwinds, lockdowns in China and the roll-off of certain COVID-related revenues. We continue to own the stock.

– STAAR Surgical is a developer and manufacturer of implantable collamer lenses for vision correction. The stock declined after management lowered its 2022 revenue guidance due to the combined impacts of lockdowns in China, European headwinds, and currency factors. We continue to own the stock.

• Within sector allocation, the Fund's underweight position in energy detracted from returns.

• The Fund did not invest in derivatives during the reporting period.

Portfolio highlights

Performance Food Group markets and distributes food and food-related products to a variety of customers including restaurants, schools, business, hospitals, convenience stores and theaters. The company operates in the US and Canada, offering foods such as meats, fruits, vegetables and desserts, as well as paper products, including pizza boxes, disposable napkins, plates, and cups. We believe the company has an opportunity to grow sales both organically and through mergers and acquisitions as it consolidates smaller companies in the industry.

Ryman Hospitality Properties specializes in group-oriented and destination hotel assets in urban and resort markets. We believe the company should benefit from increased demand for corporate meetings and events after several years of limited activity during the early stages of the COVID-19 pandemic. Additionally, the company has been making investments in its existing properties to increase the number of rooms available, which can help drive growth over time.

Pure Storage is a leading provider of flash storage arrays for high performance workloads, including server consolidation, desktop virtualization, database and cloud computing. We believe the company is positioned to continue to gain share in the enterprise all-flash array market. The company is also seeking to enable hyperscalers' ambitions and has a partnership with Meta to power its AI/Metaverse ambitions.

Lattice Semiconductor is a leading provider of Field Programmable Gate Arrays (FPGAs). The company's integrated circuits (ICs) can be programmed and re-programmed via software to adapt to the evolving needs of larger systems. We believe the company's FPGA technology will continue to benefit from the rise of fast-growing applications, including edge computing, artificial intelligence, system security, 5G, factory automation and robotics. The company should also benefit from continued new product introductions increasing their addressable market, as well as margin expansion opportunities through pricing power and scale.

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 and administrator ("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, dividend expense and security loan fees for securities sold short and extraordinary expenses, such as proxy-related expenses), through the period ending October 28, 2023, do not exceed 1.24% for Class A 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 fiscal years following the date on 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 the lesser of any applicable expense limit that is in place for the Fund (i) at the time of the waiver or reimbursement or (ii) at the time of the recoupment. 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.

³ 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.

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

UBS Sustainable Development Bank Bond Fund

Portfolio performance

For the six months ended December 31, 2022 (the "reporting period"), Class P shares of UBS Sustainable Development Bank Bond Fund (the "Fund") returned -3.12% while Class P2 shares returned -3.05%. For comparison purposes, the Bloomberg U.S. Treasury Index (the "Index") returned -3.66%. The Fund's secondary benchmark, the Solactive UBS Global Multilateral Development Bank Bond USD 40% 1-5 Year 60% 5-10 Year Total Return Index, returned -3.03% during the reporting period. 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.

Fund overview

The Fund seeks capital appreciation. Under normal circumstances, the Fund invests at least 80% of its net assets in bonds and/or instruments that provide exposure to bonds issued by development banks. Development banks are financial organizations formed by government entities to promote economic and social development.

The development bank bond market typically follows high-quality US government bonds. As each of the global Multilateral Development Banks ("MDB") are supranational entities backed by multiple member governments, MDBs historically have a similar credit profile to major sovereign issuers, such as the US government. Consequently, MDB bonds have generally delivered comparable returns to US Treasurys.

Market review

During the reporting period the financial markets were still dominated by inflation worries and its challenge for central banks. Central banks needed to balance the impacts of high inflation, a tight labor market and a weakening but still resilient economy. The US Federal Reserve continued hiking and raised its target rate three times by 75 basis points (0.75%) and once by 50 basis points (0.50%) during the reporting period. US yields also kept rising and the interest rate curve kept flattening. The yield of 2-year US Treasurys rose by roughly 1.65%, whereas the yield of 10-year Treasurys rose "only" around 1%, which caused the yield curve to invert.

In this environment, US Treasurys outperformed riskier parts of the US fixed income markets. Sustainable development banks (SDB) showed some resiliency to rising credit spreads and performed in-line with US Treasurys.

Portfolio performance summary

The Fund seeks to minimize tracking error relative to its secondary benchmark (before fees and expenses), which is constructed from a blend of two market indexes designed to measure the performance of the US dollar-denominated multilateral development bank bond market. During the reporting period, the Fund modestly underperformed its secondary benchmark. Transaction costs associated with the management of the Fund's portfolio, as well as fees and expenses, were headwinds for results, and did not totally offset the positive impact from sector positioning. Additionally, US duration positioning was a small detractor from returns. The Fund did not invest in derivatives during the reporting period.

The Trust, with respect to the Fund, and UBS Asset Management (Americas) Inc., the Fund's investment advisor and administrator ("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, such as proxy-related 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 28, 2023, do not exceed 0.25% for Class P shares and 0.15% for Class P2 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 fiscal years following the date on 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 the lesser of any applicable expense limit that is in place for the Fund (i) at the time of the waiver or reimbursement or (ii) at the time of the recoupment. 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.

UBS Multi Income Bond Fund

Portfolio performance

For the six months ended December 31, 2022 (the "reporting period"), Class A shares of UBS Multi Income Bond Fund (the "Fund") returned 1.71% (Class A shares returned -2.13% after the deduction of the maximum sales charge), while Class P shares returned 1.84%. For comparison purposes, the Bloomberg U.S. Aggregate Bond Index (the "Index") returned -2.97%. (Class P shares have lower expenses than the other share class of the Fund. Returns for all share classes over various time periods are shown on page 82; 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.)

During the reporting period, we used derivatives for risk management purposes and as a tool to help enhance returns across various strategies. A number of credit derivatives, including index (CDX) options, were used to manage the Fund's credit exposure. For active currency management, we utilized foreign exchange (FX) forwards. For managing interest rate exposure, we utilized interest rate futures during the reporting period. Derivatives were just one tool, among others, that we used to implement our overall strategy. Looking at the impact of derivatives in isolation is not very meaningful and could potentially be misleading, as oftentimes they are used as a complement or risk mitigant to other existing positions in the portfolio. The Fund is formerly known as UBS Total Return Bond Fund and was repositioned to the current strategy on June 13, 2022.

Portfolio performance summary

What worked:

• Active Duration Management: The strategy follows a flexible approach to duration management and the Fund was strategically underweight duration against the benchmark. Duration management tools, including interest rate derivatives, were particularly additive in this environment

• Overweight Corporate Bonds: Transitioning from an underweight to an overweight position vs. benchmark was additive in a period in which credit spreads moved tighter, particularly during the latter part of the reporting period. Issuer selection in both investment-grade and high-yield corporates also benefited performance.

• Underweight Mortgage-Backed Securities (MBS): An underweight vs. benchmark contributed positively to returns as MBS spreads widened over the reporting period.

• Treasury Inflation-Protected Securities (TIPS) Allocation: The allocation and overweight to US TIPS vs. benchmark had periods of strong performance during the reporting period.

What didn't work:

• Commercial Mortgage-Backed Security (CMBS) Allocation: The allocation to CMBS detracted from returns as their spreads widened over the reporting period.

Market outlook

We added back some duration during the latter part of the reporting period but remain strategically underweight, maintaining discipline by adding exposure when rates hit upper bounds of our expected ranges. We're still apt to seek opportunities to add duration as early 2023 progresses, and are actively looking for attractive entries in rates markets provided our conditions are satisfied. In our view, the 10-year Treasury is likely to remain rangebound in the near term, still hemmed in by the need to maintain tighter financial conditions for a prolonged period in order to combat inflation.

UBS Multi Income Bond Fund

We've also partially unwound long TIPS positions in the portfolio, taking profits while likely looking to continue reducing exposure. This changing tact has been driven by expectations of a decline in the Consumer Price Index (CPI), the probability of a lower positive carry (incremental yield) environment, already lessened liquidity in the space, and an unsupportive technical backdrop.

Corporates have traded in a range to finish the year, buoyed by a dearth of supply and modest appetite for yield on the one hand, but caution on economic prospects and in turn corporate profits on the other. A structural shortage of workers in the US has lent to persistently low unemployment and strong wages, continuing to offset tightening financial conditions. This represents a major market theme as we enter 2023 and one market participants are keenly aware of.

Still, measures of investor derivative positioning at year-end suggests a calming credit market that expects a more positive environment in the short-term. With imminent recession unlikely, and probability of a severe recession low, our core view and positioning related to credit remains unchanged—maintaining only a slight overweight sourced predominantly on the short-end of the credit curve. Fourth quarter 2022 earnings announcements will be closely watched for any wavering on forward outlook.

Average annual total returns for periods ended 12/31/22 (unaudited)

	6 months			1 year			5 years			10 years or Since inception
Before deducting maximum sales charge
Class A¹		1.71	%		(11.97	)%		(0.20	)%		0.06	%

Bloomberg US Aggregate Bond Index⁴		(2.97	)		(13.01	)		0.02			1.06

The annualized gross and net expense ratios as in the October 28, 2022 prospectuses were as follows: Class A—1.93% and 0.91%; Class P—1.72% and 0.66%. 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 and administrator ("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, such as proxy-related expenses), through the period ending October 28, 2023, do not exceed 0.90% for Class A shares and 0.65% 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 fiscal years following the date on 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 the lesser of any applicable expense limit that is in place for the Fund (i) at the time of the waiver or reimbursement or (ii) at the time of the recoupment. 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 Class A is September 29, 2016.

² 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 day-to-day management of, and investment decisions for, the Fund and the Predecessor Fund were made by the same portfolio management team until the June 2022 Fund repositioning. The Funds had generally similar investment objectives and strategies until the June 2022 Fund repositioning from a Core Plus to a Multi Income Bond strategy. Therefore the information shown above reflects the historical performance of the Predecessor Fund for periods prior to the Reorganization and may not be representative of performance of the Fund. 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.

³ Maximum sales charge for Class A shares is 3.75%. Class A shares bear ongoing 12b-1 service fees.

⁴ The Bloomberg US Aggregate Bond 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. Inception return for the Index is for the 10 years ended.

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

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, July 1, 2022 to December 31, 2022 (unless otherwise noted).

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 hypo- thetical 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.

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 eleven Funds available for investment, each having its own investment objectives and policies: UBS All China Equity Fund, UBS Dynamic Alpha Fund, UBS Global Allocation Fund, UBS Emerging Markets Equity Opportunity Fund, UBS Engage For Impact Fund, UBS International Sustainable Equity Fund, UBS US Dividend Ruler Fund, UBS US Quality Growth At Reasonable Price Fund, UBS U.S. Small Cap Growth Fund, UBS Municipal Bond Fund, UBS Sustainable Development Bank Bond Fund, and UBS Multi Income Bond Fund (formerly, UBS Total Return 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 Sustainable Development Bank 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 and Class P shares, with the exception of (1) UBS All China Equity Fund, UBS Emerging Markets Equity Opportunity Fund, UBS Engage For Impact Fund, UBS International Sustainable Equity Fund and UBS Sustainable Development Bank Bond Fund, which currently also offer Class P2 shares and (2) UBS US Dividend Ruler Fund and UBS US Quality Growth At Reasonable Price Fund, which currently only offer 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, fee waiver/expense cap/expense reimbursement arrangements 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 and Class P2 shares have no service or distribution plan.

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.

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 December 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2022-06 ("ASU 2022-06"), "Reference Rate Reform (Topic 848)". ASU 2022-06 is an update of ASU 2020-04, which is in response to concerns about structural risks of interbank offered rates, and particularly the risk of cessation of LIBOR, regulators have undertaken reference rate reform initiatives to identify alternative reference rates that are more observable or transaction based and less susceptible to manipulation. ASU 2020-04 provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. ASU 2020-04 is elective and applies to all entities, subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The ASU 2022-06 update clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The amendments in this update are effective immediately through December 31, 2024, for all entities. Management does not expect ASU 2022-06 to have a material impact on the financial statements.

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 net of withholding taxes 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.

The Funds do not generally isolate the effect of fluctuations in foreign exchange rates from the effect of the changes in the 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 predominantly 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.

Many financial instruments, financings or other transactions to which a Fund may be a party use or may use a floating rate based on the London Interbank Offered Rate ("LIBOR"). LIBOR is widely used in financial markets. In July 2017, the United Kingdom's financial regulatory body announced that after 2021 it will cease its active encouragement of banks to provide the quotations needed to sustain LIBOR. That announcement suggests that LIBOR may cease to be published or utilized after that time. Various financial industry groups have begun planning for that transition, but the effect of the transition process and its ultimate success cannot yet be determined. The transition process may lead to increased volatility and illiquidity in markets for instruments the terms of which are based on LIBOR. It could also lead to a reduction in the value of some LIBOR-based investments and reduce the effectiveness of new hedges placed against existing LIBOR-based investments. Since the usefulness of LIBOR as a benchmark could deteriorate during the transition period. The willingness and ability of issuers to include enhanced provisions in new and existing contracts or instruments also remains uncertain. Any of these factors may adversely affect a Fund's performance or NAV. Certain LIBOR tenors were discontinued by the end of 2021, while the discontinuation of others have been extended to June 2023.

Certain impacts to public health conditions particular to the coronavirus "COVID-19" outbreak that occurred may have a significant negative impact on the operations and profitability of the issuers of the Funds' investments. The extent of the impact to the financial performance of the Funds will depend on future developments, including (i) the duration and spread of the outbreak, (ii) the restrictions and advisories, (iii) the effects on the financial markets, and (iv) the effects on the economy overall, all of which are highly uncertain and cannot be predicted.

The conflict between Ukraine and the Russian Federation has resulted in significant volatility and uncertainty in financial markets. NATO, EU and G7 member countries have imposed severe and coordinated sanctions against Russia. Restrictive measures have also been imposed by Russia, and some securities traded in that country have materially declined in value and/or may no longer be tradable. These actions have resulted in significant disruptions

to investing activities and businesses with operations in Russia. The longer-term impact to geopolitical norms, supply chains and investment valuations is uncertain.

Valuation of investments

Each Fund generally calculates its net asset value on days that the New York Stock Exchange ("NYSE") is open. The Fund calculates net asset value 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 Fund does not price its shares, on most national holidays and Good Friday. To the extent that the Fund's assets are traded in other markets on days when the NYSE is not open, the value of the 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, the 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 the 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 Fund normally obtains market values for its 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.

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 U.S. 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 Fund invests 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 the Fund's net asset value. However, if the Fund determines 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, Level 2 and Level 3 of the fair valuation hierarchy at the end of the reporting period.

124

The UBS Funds

Notes to financial statements (unaudited)

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 Fund's 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 U.S. dollars on the basis of the foreign currency exchange rates prevailing at the time such valuation is determined by the Fund's 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 designated UBS AM as the valuation designee pursuant to Rule 2a-5 under the 1940 Act, and delegated to UBS AM the responsibility for making fair value determinations with respect to portfolio holdings. UBS AM, as the valuation designee, is responsible for periodically assessing any material risks associated with the determination of the fair value of investments; establishing and applying fair value methodologies; testing the appropriateness of fair value methodologies; and overseeing and evaluating third-party pricing services. UBS AM has the Equities, Fixed Income, and Multi-Asset Valuation Committee (the "VC") to assist with its designated responsibilities as valuation designee with respect to the Portfolios' 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 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:

125

The UBS Funds

Notes to financial statements (unaudited)

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 risks.

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

In accordance with the requirements of US GAAP, a fair value hierarchy has been included near the end of each Fund's Portfolio of investments.

Investments

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.

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 Mortgage Association or FNMA) and Freddie Mac (formally known as the Federal Home Loan Mortgage Company 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

126

The UBS Funds

Notes to financial statements (unaudited)

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.

Real estate investment trusts: Certain Funds may invest in real estate investment trusts ("REITs"). Distributions from a REIT are initially recorded as dividend income and may subsequently be recharacterized by the REIT at the end of its tax year as a return of capital and/or capital gains. The Fund estimates the character of dividends received from REITs for financial reporting purposes based on the distribution history of each REIT. Once actual distribution characterizations are made available by the REITs, typically after calendar year end, the Fund updates its accounting and/or tax books and records.

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 expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities, if any, is included in each Fund's portfolio footnotes.

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 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, U.S. 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.

Short sales: UBS Dynamic Alpha Fund, UBS U.S. Small Cap Growth Fund and UBS Multi Income 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. The Fund segregates collateral, consisting of cash or liquid assets, sufficient to collateralize the market value of the investments sold short. The Fund incurs transaction costs, including dividend expense, borrowing costs and interest 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 December 31, 2022, UBS Dynamic Alpha Fund, UBS U.S. Small Cap Growth Fund and UBS Multi Income Bond Fund did not engage in short sale transactions.

Treasury Inflation Protected Securities: The Funds may purchase Treasury inflation protected securities ("TIPS") which are debt securities issued by the US Treasury. TIPS adjust for inflation based on changes in the published Consumer Price Index ("CPI"). During periods of inflation when the CPI index increases, the principal amount of the debt to which the rate of interest is applied increases, which in turn increases the yield. During periods of deflation when the CPI index decreases, the principal amount of the debt to which the rate of interest is applied decreases, which in turn lowers the yield. At maturity, TIPS return the higher of the principal amount at maturity or the initial face amount of the debt.

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, options on futures contracts 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 Funds pay a premium which is included on 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 Fund of investments and are included in the Statement of assets and liabilities in investments, 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, options on futures contracts 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 on 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 the 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 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.

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 Fund trades and holds certain fair valued derivative contracts that constitute guarantees. Such contracts include written put options, where the Fund will be obligated to purchase securities at specified prices (i.e. the options are exercised by the counterparties). It also includes written swaptions, where the Fund will be obligated to enter into a swap agreement. 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.

Written options, if any, are shown as portfolio holdings within the Portfolio of investments and are included in the Statement of assets and liabilities in options and swaptions written, at value. At December 31, 2022, the Funds did not hold any written 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, except that in the case of certain futures contracts that are held through swap 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 risks, including market, interest rate and equity risks. 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.

Futures contracts, if any, are shown as fund holdings within the Portfolio of investments. Variation margin, if applicable, is shown in Variation margin receivable or payable on futures contracts within the Statement of Assets and Liabilities.

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.

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 or loss on swap agreements, in addition to realized gain or 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

129

The UBS Funds

Notes to financial statements (unaudited)

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 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 credit indices—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, risks, and transaction costs different from those associated with ordinary portfolio security transactions, including assumptions about market conditions, interest rates, and other applicable factors. As a result, the performance of the Fund will be different than if it had used ordinary portfolio security transactions. 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, the 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.

Swap agreements, if any, are shown as portfolio holdings within the Portfolio of investments.

Forward foreign currency contracts: Certain Funds may enter into forward foreign currency contracts as part of their investment objective, for purposes of risk management or to hedge the US dollar value of portfolio securities denominated in a particular 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.

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 December 31, 2022.

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 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 Fund's Portfolio of investments. The aggregate fair value of assets that are already posted as collateral as of December 31, 2022 is reflected in the Statement of assets and liabilities.

At December 31, 2022, 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 their 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 December 31, 2022, derivative assets and liabilities (by type) on a gross basis and derivatives subject to an enforceable master netting arrangement ("MNA") or similar were as follows:

Securities lending

Each Fund may lend securities up to 33¹/₃% of its total assets to qualified broker-dealers or institutional investors. The loans are initially secured by cash, U.S. government securities and irrevocable letters of credit in an amount at least equal to 102% of the market value of the securities loaned with respect to domestic securities and 105% of the market value of the securities loaned with respect to foreign securities. In the event that the market value of the cash, U.S. government securities, and irrevocable letters of credit securing the loan falls below 100% of the market value for domestic securities, and 103% for foreign securities, the borrower must provide additional cash, U.S. government securities, and irrevocable letters of credit so that the total securing the loan is at least 102% of the market value for domestic securities and 105% of the market value for foreign securities.

Each Fund will regain ownership of loaned securities to exercise certain beneficial rights; however, each Fund may bear the risk of delay in recovery of, or even loss of rights in, the securities loaned should the borrower fail financially. The Fund receives compensation for lending its securities from interest or dividends earned on the cash, U.S. government securities and irrevocable 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 State Street Navigator Securities Lending Government Money Market Fund, which is included in the Fund's Portfolio of investments. State Street Bank and Trust Company serves as the Fund's lending agent.

At December 31, 2022, the following Funds had securities on loan at value, cash collateral and non-cash collateral as follows:

Bank line of credit

The Fund participates with other funds managed by UBS AM in a $185 million committed credit facility (the "Committed Credit Facility") with State Street Bank and Trust Company. 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. The funds covered by the Committed Credit Facility have 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 December 31, 2022, the following Funds had borrowings as follows:

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 December 31, 2022, there were no recaptured commissions on the Funds. The commission recapture arrangement was terminated on August 10, 2022.

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 year ended June 30, 2022 was as follows:

Fund	Distributions paid from tax-exempt income		Distributions paid from ordinary income		Distributions paid from long term realized capital gains		Total distributions paid

Net capital losses recognized by the Funds, 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.

At June 30, 2022, the following Funds had net capital losses that will be carried forward indefinitely, as follows:

UBS All China Equity Fund	$	179,338	$	13,189	$	192,527

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 December 31, 2022, 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 period ended December 31, 2022, the Funds did not incur any interest or penalties.
