UBS U.S. Allocation Fund

Semiannual Report | February 28, 2023

UBS U.S. Allocation Fund

April 15, 2023

Dear shareholder,

We present you with the semiannual report for UBS U.S. Allocation Fund (the "Fund") for the six months ended February 28, 2023.

Performance

Over the six months ended February 28, 2023, the Fund's Class A shares returned 0.78% before deducting the maximum sales charge and returned -4.75% after deducting the maximum sales charge. During the same period, the Fund's primary benchmark, the S&P 500 Index,¹ which tracks large cap US equities, returned 1.26%. Since the Fund invests in both stocks and bonds, we believe it is appropriate to also compare its performance to the UBS U.S. Allocation Fund Benchmark (the Fund's secondary benchmark),² which returned 0.63% during the period. (Returns for all share classes over various time periods and descriptions of the indices are shown in "Performance at a glance" on page 6; please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or on the redemption of Fund shares.)

Market commentary

Q. How would you describe the economic environment and markets during the reporting period?

A. The US economy faced several headwinds, including four-decade-high inflation, aggressive Federal Reserve (the "Fed") monetary tightening, the repercussions from the war in Ukraine, and several geopolitical issues. However, the economy was resilient and continued to expand. Looking back, third quarter US annualized gross domestic product ("GDP") growth was 3.2%. On March 30, 2023—after the reporting period ended—the Commerce Department reported that fourth quarter annualized GDP was 2.6%. The initial estimate for first quarter 2023 GDP is scheduled to be released on April 27, 2023.

With US inflation remaining elevated and persistent, the Fed continued to aggressively raise interest rates. After raising rates four times from March 2022 through July 2022, the Fed hiked rates four additional times during the reporting period, moving the federal funds rate from a range between 2.25% and 2.50% to a range of 4.50% and 4.75%. On March 22, 2023—after the reporting period ended—the Fed raised rates another 0.25%, pushing the federal funds rate to its highest level since September 2007.

US equities were volatile overall, but modestly advanced during the reporting period. The market fell sharply over the first month of the period against a backdrop of elevated inflation and aggressive monetary policy tightening. The fallout from the war in Ukraine also weighed on investor sentiment. The US market then rallied over three of the next four months. This was due to several factors, including signs of moderating inflation, hopes that the Fed would be less aggressive in terms of future rate hikes, and that the central bank could orchestrate a "soft landing" for the economy. The market then fell over the last month of the period, as inflation remained elevated and a

robust labor market triggered concerns that rates would be "higher-for-longer" and potentially tip the economy into a recession.

The overall US fixed income market declined, as the Fed continued to 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 February 28, 2023, the yield on the US 10-year Treasury rose from 3.15% to 3.92%. (Bond yields and prices generally move in the opposite direction.) For the six-month reporting period, the overall US bond market, as measured by the Bloomberg US Aggregate Index,³ returned -2.13%. In contrast, riskier high yield bonds, as measured by the ICE BofAML US High Yield Index,⁴ gained 3.06% during the reporting period.

Portfolio commentary

What worked

•  Overall, security selection and tactical asset allocation decisions contributed to performance during the reporting period.

•  Overall, the US value equity portion of the Fund contributed to returns. Specifically, outperformance over the period was primarily led by positive stock selection in Consumer Discretionary and Health Care.

  – Broadly, our Consumer Discretionary exposure boosted relative performance, as consumer activity remained robust and supply chain and inventory challenges seemed to abate toward the end of last year.

  – Brunswick performed well on the back of strong operating expense control and positive signs of market share gains in higher horsepower engines. This was in line with our investment thesis that the company would witness reduced cyclicality in its revenues.

  – Aptiv shares also bounced amid evidence that supply chain tightness, COVID, and input cost pressure-related headwinds were moderating.

  – Las Vegas Sands was the top contributor to performance as its shares rebounded on China reopening, which renewed optimism around the impending recovery of casinos in its core Macau market.

•  In the US growth equity portion of the Fund, positive stock selection contributed to relative performance, but was ultimately offset by sector allocation headwinds. From a sector perspective, our overweight to Health Care and underweight to Real Estate contributed to relative performance.

  – United Rentals: The company's shares rose on the back of strong earnings and better-than-expected 2023 guidance. We continue to like United Rentals, as it is one of the biggest players in the North American equipment rental industry. We believe the company will continue to benefit from an ongoing preference shift toward renting versus owning equipment.

³  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.

⁴  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.

  – TransDigm: TransDigm benefited from strong earnings and continued growth in commercial aftermarket, with high-teens growth expected into 2023. We continue to like the company and believe it should benefit from recovery of air travel from China's reopening.

  – DexCom: Shares of DexCom outperformed after it received Food and Drug Administration approval for its G7 glucose-monitoring device. We remain confident on the potential for the stock to significantly grow its enterprise value over the next few years from current levels.

•  Overall, asset allocation was positive for performance during the reporting period.

  – During the period, we had an underweight to equities and an overweight to fixed income versus the UBS U.S. Allocation Fund benchmark.

  – Overall, US equity markets made strong gains over the fourth quarter of 2022 due to investors balancing the caution that the pace of Fed policy tightening could slow with signs that elevated inflation could be cooling. In addition, positive economic indicators around consumer spending have been resilient from a strong labor market, despite the impact of higher prices on household budgets.

  – Our underweight to broad equities slightly detracted from relative performance as risk assets rebounded over the reporting period. However, our overweight to US Energy added positively to performance due to global supply shortages. Moreover, an overweight to fixed income mainly around asset-backed securities ("ABS") contributed strongly to returns over the period. Specifically, an underweight to mortgage-backed securities ("MBS") contributed to performance relative to the benchmark as we remained cautious of mortgages given elevated volatility and a technical environment that remains unsupportive of the sector broadly. For comparison purposes, neutral Index weights for the Fund are 65.0% equities and 35.0% fixed income.⁵

•  Relative to the benchmark, the use of fixed income and equity derivatives (futures, options, and swaps) contributed to results. These derivative instruments, which were utilized to manage the Fund's fixed income and equity exposure, were positive for performance.

What didn't work

•  In the US value equity portion of the Fund, stock selection in Energy and Materials detracted the most.

  – After a period of strong performance earlier in 2022, our Energy and Materials exposure detracted over the period, as we witnessed a sharp pullback in commodity prices.

  – Williams Companies—a gas pipeline company—was the main detractor as its share price was weighed by falling natural gas prices. We continue to hold this stock.

  – Similarly, CF Industries' shares fell on the back of declining nitrogen fertilizer prices. We continue to hold this stock.

⁵  Allocations include derivative exposure.

UBS U.S. Allocation Fund

•  Overall, the US growth equity portion of the Fund detracted from returns. Specifically, our overweight to both consumer Discretionary and Communication Services detracted. The main individual detractors were:

  – Fidelity National Information Services: The stock sold off after earnings in November 2022, as the company outlined revenue growth pressures from a slower sales pipeline and as their small merchant acquiring business has seen revenue pressures. The company also discussed inflation pressure and lumpy license revenues which have been imposing margin pressure throughout the reporting period. While we believe the company had solid operating businesses, we also felt current pressure on this business will take time to work through and unlock value. We therefore exited our position in the stock in the U.S. Growth equity portion of the Fund during the fourth quarter of 2022.

  – Amazon.com: Amazon.com's shares fell after earnings revealed a slowdown in enterprise cloud demand and a fourth quarter outlook that reflected slowing consumer spending. These factors offset strong advertising performance and incremental gains with utilization of excess fulfillment capacity. We still like Amazon.com shares for the company's longer-term expansion in higher margin AWS (Amazon Web Services) and advertising against a backdrop of lower fulfillment capacity cap and higher utilization. We recognize that a weaker macroeconomic environment slows progress in these areas. We continue to hold this stock.

  – NVIDIA: Our underweight to NVIDIA detracted from relative performance after the stock rallied roughly 50% from end of its December 2022 lows. The rebound was spurred in part by easing sentiment for technology names across the board. It was also aided by optimism that hyperscale capital expenditures are improving and that ChatGPT and other artificial intelligence (AI) integrations will be meaningful demand drivers for cloud computing capacity. While the company seems to be making progress with channel inventory and new consumer and enterprise product cycles, we remain mindful of macro pressures on data centers, as well as export bans to China, which impact NVDIA's most advanced products. Our preferred overweight exposure in elite semis (most comparable to NVDIA in terms of both 3-5 year growth outlook and technology lead) is Advanced Micro Devices which meaningfully outperformed NIVIDA in the fourth quarter of 2022. We continue to hold this stock.

The annualized gross and net expense ratios, respectively, for each class of shares as in the December 29, 2022 prospectus, were as follows: Class A—0.99% and 0.99%; and Class P—0.72% and 0.72%.

Net expenses reflect fee waivers and/or expense reimbursements, if any, pursuant to an agreement that is in effect to cap the expenses. The Fund and UBS Asset Management (Americas) Inc. have entered into a written agreement, separate from UBS AM's investment advisory agreement with the Fund, whereby UBS AM has agreed to permanently reduce its management fees based on the Fund's average daily net assets to the following rates: $0 to $250 million: 0.50%; in excess of $250 million up to $500 million: 0.45%; in excess of $500 million up to $2 billion: 0.40%; over $2 billion: 0.35%. Effective December 29, 2022, UBS AM has contractually undertaken to waive fees/reimburse a portion of the Fund's expenses, when necessary, so that the ordinary total annual operating expenses of each class through December 31, 2023 (excluding dividend expense, borrowing costs and interest expense relating to short sales, and expenses attributable to investments in other investment companies, interest, taxes, brokerage commissions, trustee elections as well as other matters related to shareholder meetings (unless otherwise separately agreed by UBS AM), and extraordinary expenses, if any) would not exceed 1.15% for Class A and 0.90% for Class P.

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

⁴  The UBS U.S. Allocation Fund Benchmark is an unmanaged benchmark compiled by the Advisor, constructed as follows: from June 1, 2005 until present: 65% Russell 3000 Index, 30% Bloomberg US Aggregate Bond Index, and 5% ICE BofAML US High Yield Cash Pay Constrained Index. Investors should note that indices do not reflect the deduction of fees and expenses.

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

Understanding your Fund's expenses (unaudited)

As a shareholder of the Fund, 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 the 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, September 1, 2022 to February 28, 2023.

Actual expenses (unaudited)

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 for each class of shares 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 (unaudited)

The second line for each class of shares in the table below provides information about hypothetical account values and hypothetical expenses based on the 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 the Fund's actual return for each class of shares. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the 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 Fund 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 Fund 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.

		Beginning account value September 1, 2022		Ending account value February 28, 2023		Expenses paid during period1		Expense ratio during the period
Class A	Actual	$	1,000.00	$	1,007.80	$	5.03		1.01	%
	Hypothetical (5% annual return before expenses)		1,000.00		1,019.80		5.06		1.01
Class P	Actual		1,000.00		1,008.90		3.74		0.75
	Hypothetical (5% annual return before expenses)		1,000.00		1,021.10		3.76		0.75

¹  Expenses are equal to the Fund annualized net expense ratios, multiplied by the average account value over the period, multiplied by 181 divided by 365 (to reflect the one-half year period).

Organization and significant accounting policies

UBS U.S. Allocation Fund (the "Fund") is a series of UBS Investment Trust (the "Trust") and is registered with the US Securities and Exchange Commission ("SEC") under the Investment Company Act of 1940 (the "1940 Act"), as amended, as an open-end, diversified management investment company. The Trust was organized on March 28, 1991, as a business trust under the laws of the Commonwealth of Massachusetts and currently has one operating series.

UBS Asset Management (Americas) Inc. ("UBS AM" or the "Advisor") serves as the investment advisor and administrator for the Fund. UBS Asset Management (US) Inc. ("UBS AM (US)") serves as the principal underwriter for the Fund. 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 Fund currently offers Class A and Class P shares. Each class represents interests in the same assets of the Fund, and the classes are identical except for differences in their sales charge structures, ongoing service and distribution charges and certain transfer agency and related services expenses. All classes of shares have equal voting privileges except that each class has exclusive voting rights with respect to its service and/or distribution plan, if any. Class P shares have no service or distribution plan.

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

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 Fund's 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, 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 on the ex-dividend date ("ex-date") except in

34

UBS U.S. Allocation Fund

Notes to financial statements (unaudited)

the case of certain dividends from foreign securities which are recorded as soon after the ex-date as the 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 investment income and distributions from 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 Fund 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 Fund does not generally isolate the effect of fluctuations in foreign exchange rates from the effect of the changes in market prices of securities. However, the Fund does 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 the Fund invests.

The ability of the issuers of debt securities held by the Fund 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 the 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

35

UBS U.S. Allocation Fund

Notes to financial statements (unaudited)

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 the 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 Fund's investments. The extent of the impact to the financial performance of the Fund 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.

Valuation of investments

The Fund generally calculates its net asset value on days that the New York Stock Exchange ("NYSE") is open. The Fund calculates net asset value separately for each class as of the close of regular trading on the NYSE (generally, 4:00 p.m., Eastern time). The NYSE normally is not open, and the 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.

The 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 US and foreign stock exchanges normally are valued at the market closing price, the last sale price on the day the securities are valued or, lacking any sales on such day, at the last available bid price. Investments listed on foreign stock exchanges may be fair valued based on significant events that have occurred subsequent to the close of the foreign markets. In cases where investments are traded on more than one exchange, the investments are valued on the exchange designated as the primary market by UBS AM. If a market value is not readily available from an independent pricing source for a particular investment, that investment is valued at fair value as determined in good faith by or under the direction of the Fund'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 may be 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

36

UBS U.S. Allocation Fund

Notes to financial statements (unaudited)

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.

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

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 US 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, if any, 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 Fund's 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 the

37

UBS U.S. Allocation Fund

Notes to financial statements (unaudited)

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 the Fund's investments. These inputs are summarized into the three broad levels listed below:

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

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

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

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

Investments

Asset-backed securities—The Fund 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—The Fund 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 secu-

Notes to financial statements (unaudited)

rities are divided into classes or tranches with each class having its own characteristics. Investors typically receive payments out of the interest and principal on the underlying mortgages. The portions of these payments that investors receive, as well as the priority of their rights to receive payments, are determined by the specific terms of the CMO class.

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

Real estate investment trusts—The Fund 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.

Repurchase agreements—The Fund may purchase securities or other obligations from a bank or securities dealer (or its affiliate), subject to the seller's agreement to repurchase them at an agreed upon date (or upon demand) and price. The Fund maintains custody of the underlying obligations prior to their repurchase, either through its regular custodian or through a special "tri-party" custodian or sub-custodian that maintains a separate account for both the Fund and its counterparty. The underlying collateral is valued daily in an effort to ensure that the value, including accrued interest, is at least equal to the repurchase price.

Repurchase agreements carry certain risks not associated with direct investments in securities, including a possible decline in the market value of the underlying obligations. If their value becomes less than the repurchase price, plus any agreed-upon additional amount, the counterparty must provide additional collateral so that the collateral is at least equal to the repurchase price plus any agreed-upon additional amount. The difference between the total amount to be received upon repurchase of the obligations and the price that was paid by the Fund upon acquisition is accrued as interest and included in its net investment income. In the event of default of the obligation to repurchase, the Fund generally has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Repurchase agreements involving obligations other than U.S. government securities (such as commercial paper, corporate bonds, equities and mortgage loans) may be subject to special risks and may not have the benefit of certain protections in the event of counterparty insolvency. If the seller (or seller's guarantor, if any) becomes insolvent, the Fund may suffer delays, costs and possible losses in connection with the disposition or retention of the collateral. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. The Fund intends to enter into repurchase agreements only in transactions with counterparties believed by UBS AM to present minimal credit risk.

39

UBS U.S. Allocation Fund

Notes to financial statements (unaudited)

The Fund may participate in joint repurchase agreement transactions with other funds managed, or advised by UBS AM in accordance with an exemptive order granted by the SEC pursuant to Section 17(d) of the 1940 Act and Rule 17d-1 thereunder. Under certain circumstances, the Fund may engage in a repurchase agreement transaction with a yield of zero in order to invest cash amounts remaining in its portfolio at the end of the day in order to avoid having the Fund potentially exposed to a fee for uninvested cash held in a business account at a bank.

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

Securities traded on to-be-announced basis—The Fund 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.

Treasury Inflation Protected Securities—The Fund 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—The Fund may purchase put and call options, in order to gain exposure to or protect against changes in the markets or in an attempt to enhance income or gains. Purchasing call options tends to increase exposure to the underlying instrument. Purchasing put options tends to decrease exposure to the underlying instrument.

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

40

UBS U.S. Allocation Fund

Notes to financial statements (unaudited)

When the 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 the 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 the 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, the 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 the 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 written put options 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.

Futures contracts—The Fund may purchase or sell futures contracts as part of its investment strategy, to increase or reduce its 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, the 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 the Fund, depending on the daily fluctuations in the value of the underlying futures contracts. Such variation margin is recorded for financial statement purposes on a daily basis as an unrealized appreciation or depreciation on futures until the futures contract is closed or expires, at which time the net gain or loss is reclassified to realized gain or loss on futures.

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

Futures contracts, if any, are shown as portfolio 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—The Fund may engage in swap agreements, including, but not limited to, credit default and total return swap agreements. The 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 Fund accrues for interim payments on swap agreements on a daily basis, with the net amount recorded within unrealized appreciation or depreciation of swap agreements. Once interim payments are settled in cash, the net amount is recorded as realized gain/loss on swap agreements, in addition to realized gain/loss recorded upon the termination of swap agreements on the Statement of operations. Fluctuations in the value of swap agreements are recorded for financial statement purposes as unrealized appreciation or depreciation on swap agreements.

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

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

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

42

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). The 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 the 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 the Fund is the seller of protection are disclosed under the section "Credit default swap agreements on corporate issues and 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 the 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 notional amounts. To the extent the total return of the security or index underlying the transactions 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 received or paid, if any.

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

Derivatives by underlying risk—Investment companies value their derivatives at fair value and recognize changes in fair value through the Statement of operations. Although certain of a Fund's investments in derivatives may be intended to hedge risk from a portfolio implementation/economic perspective, derivatives are considered to be "non-hedge transactions" for purposes of disclosure under US GAAP as reflected in the Fund's financial reports.

The volume of derivatives as disclosed in the Fund's Portfolio of investments is representative of the volume of derivatives outstanding during the period ended February 28, 2023.

Swap agreements and options written entered into by the Fund 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 Portfolio of investments. The aggregate fair value of assets that are already posted as collateral as of February 28, 2023 is reflected in the Statement of assets and liabilities.

At February 28, 2023, the Fund had the following derivatives categorized by underlying risk:

Asset derivatives¹

	Interest rate risk		Foreign exchange risk		Credit risk		Equity risk		Total value
Futures contracts	$	7,170	$	—	$	—	$	480,175	$	487,345

The change in net unrealized appreciation (depreciation) of options and swaptions purchased is shown in the Statement of operations in change in net unrealized appreciation (depreciation) on investments.

Offsetting of certain derivatives—The Fund typically enters into International Swaps and Derivatives Association, Inc. Master Agreements ("ISDA Master Agreements") or similar master agreements with its OTC derivative contract counterparties in order to, among other things, reduce its credit risk to counterparties. ISDA Master Agreements include provisions for general obligations, representations, collateral and events of default or termination. Under an ISDA Master Agreement, the Fund 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 February 28, 2023, 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:

Investment advisor and administrator fees and other transactions with affiliates

The Board has approved an Investment Advisory and Administration Contract (the "Advisory Contract"), under which UBS AM serves as investment advisor and administrator of the Fund. In accordance with the Advisory Contract, the Fund is to pay UBS AM an investment advisory and administration fee, which is to be accrued daily and paid monthly, at an annual rate of 0.50% of the Fund's average daily net assets up to $250 million and 0.45% thereafter.

UBS AM has agreed to permanently reduce its advisory and administration fee based on the Fund's average daily net assets so that it is assessed as follows: $0 to $250 million—0.50%; in excess of $250 million up to $500 million—0.45%; in excess of $500 million up to $2 billion—0.40%; and over $2 billion—0.35%. Accordingly, for the period ended February 28, 2023, UBS AM did not waive any investment advisory and administration fees. At February 28, 2023, the Fund owed UBS AM $83,819 for investment advisory and administration fees.

UBS AM has contractually undertaken to waive fees/reimburse a portion of the Fund's expenses, when necessary, to maintain the total annual operating expenses (excluding (1) dividend expense, borrowing costs and interest expense relating to short sales, and (2) investments in other investment companies, interest, taxes, brokerage commissions, trustee elections as well as other matters related to shareholder meetings (unless otherwise separately agreed by UBS AM), and extraordinary expenses, if any) of Class A and Class P shares at a level not to exceed 1.15% and 0.90%,respectively through December 31, 2023. The Fund will repay UBS AM for any previously waived fees/reimbursed expenses during the three-year period following August 31, 2020, to the extent that operating expenses (with certain exclusions such as dividend expense, borrowing costs, and interest expense relating to short sales, and interest, taxes, brokerage commissions, trustee elections as well as other matters related to shareholder meetings (unless otherwise separately agreed by UBS AM), and extraordinary expenses, if any) are otherwise below the expense caps in effect at the time the fees or expenses were waived/reimbursed. For the period ended February 28, 2023, the Fund had no fee waivers/expense reimbursements subject to repayment. Accordingly, for the period ended February 28, 2023 UBS AM did not waive any investment advisory and administration fees.

During the period ended February 28, 2023, the Fund engaged in purchase and sale transactions where an affiliate was underwriter. In such cases, the affiliate underwriter was not compensated and each trade was approved by the Board.

Service and distribution plans

UBS AM (US) is the principal underwriter of the Fund's shares. The Fund has adopted service and/or distribution plans (the "Plans") pursuant to Rule 12b-1 under the 1940 Act for Class A shares. The Plans govern payments made for the expenses incurred in the service and/or distribution of Class A shares. The Fund pays UBS AM (US) monthly service fees at an annual rate of 0.25% of the average daily net assets of Class A shares. At February 28, 2023, the Fund owed UBS AM (US) $35,640 for service and distribution fees.

UBS U.S. Allocation Fund

Notes to financial statements (unaudited)

UBS AM (US) also receives the proceeds of the initial sales charges paid upon the purchase of Class A shares and the contingent deferred sales charges paid by shareholders upon certain redemptions of Class A shares. UBS AM (US) has informed the Fund that for the period ended February 28, 2023, it earned $245 in initial sales charges on Class A shares.

Transfer agency and related services fees

UBS Financial Services Inc. provides certain services to the Fund pursuant to a delegation of authority from BNY Mellon Investment Servicing (US) Inc. ("BNY Mellon"), the Fund's transfer agent, and is compensated for these services by BNY Mellon, not the Fund. For the period ended February 28, 2023, UBS Financial Services Inc. received from BNY Mellon, not the Fund, $20,170 of the total transfer agency and related service fees paid by the Fund to BNY Mellon.

Securities lending

The Fund may lend securities up to 33¹/₃% of its total assets to qualified broker-dealers or institutional investors. The loans are initially secured at all times by cash, US 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, US government securities, and irrevocable letters of credit securing the loan falls below 100% for domestic securities, and 103% for foreign securities, the borrower must provide additional cash, US 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.

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

At February 28, 2023, the Fund had securities on loan at value, cash collateral and non-cash collateral as follows:

Value of securities on loan		Cash collateral		Non-cash collateral*		Total collateral		Security types held as non-cash collateral
$	1,011,723	$	—	$	1,029,839	$	1,029,839	U.S. Treasury Notes and U.S. Treasury Bills

*  These securities are held for the benefit of the Fund at the Fund's custodian. The Fund cannot repledge or resell this collateral. As such, collateral is excluded from the Statement of assets and liabilities.

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 prevailing rates in effect at the time of borrowing. The Advisor has agreed to pay commitment fees on the average daily balance of the Committed Credit Facility not utilized by the Fund. Commitment fees have been allocated among the funds in the Committed Credit Facility as follows: 50% of

47

UBS U.S. Allocation Fund

Notes to financial statements (unaudited)

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 February 28, 2023, the Fund did not borrow under the Committed Credit Facility.

Purchases and sales of securities

For the period ended February 28, 2023, aggregate purchases and sales of portfolio securities, excluding short-term securities, were $65,783,287 and $70,566,045, respectively.

Shares of beneficial interest

There is an unlimited amount of $0.001 par value shares of beneficial interest authorized. Transactions in shares of beneficial interest, at $1.00 per share, were as follows:

Federal Tax Status

The Fund intends to distribute substantially all of its income and to comply with the other requirements of the Internal Revenue Code applicable to regulated investment companies. Accordingly, no provision for federal income taxes is required. 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, the Fund intends not to be subject to a federal excise tax.

The tax character of distributions paid during the fiscal year ended August 31, 2022 was as follows:

Distribution paid from	2022
Ordinary Income	$	16,715,916
Long term realized capital gains		24,548,966

The tax character of distributions paid and the components of accumulated earnings (deficit) on a tax basis for the current fiscal year will be determined after the Fund's fiscal year ending August 31, 2023.

Aggregate cost for federal income tax purposes, including derivatives, was $218,292,685; and net unrealized appreciation (depreciation), including derivatives consisted of:

Gross unrealized appreciation	$	14,659,810
Gross unrealized depreciation		(13,971,978	)
Net unrealized appreciation (depreciation)		687,832

Notes to financial statements (unaudited)

Net capital losses recognized by the Fund may be carried forward indefinitely, and retain their character as short-term and/or long-term losses.

At August 31, 2022, the Fund had no net capital loss carryforward.

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 Fund has analyzed as of February 28, 2023 that there are no significant uncertain tax positions taken or expected to be taken that would require recognition in financial statements. The Fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statement of operations. During the period ended February 28, 2023, the Fund did not incur any interest or penalties.

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

Each of the tax years in the four year period ended August 31, 2022, remains subject to examination by the Internal Revenue Service and state taxing authorities.
