Class A & P Prospectus | UBS All China Equity Fund

UBS All China Equity Fund

Investment objective

The Fund seeks to maximize capital appreciation.

Fees and expenses

These tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for a sales charge waiver or discount if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund. More information about these and other discounts and waivers, as well as eligibility requirements for each share class, is available from your financial advisor and in "Managing your fund account" beginning on page 15 of the Fund's prospectus and in "Reduced sales charges, additional purchase, exchange and redemption information and other services" beginning on page 53 of the Fund's Statement of Additional Information ("SAI"). In addition to the fees and expenses described below, you may also be required to pay commissions or other fees to your broker for transactions in Class P shares. Shares of the Fund are available in classes other than Class P that have different fees and expenses.

Different intermediaries and financial professionals may make available different sales charge waivers or discounts. These variations are described in Appendix A beginning on page A-1 of this prospectus.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods unless otherwise stated. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The costs described in the example reflect the reduction in the expenses of the Fund that would result from the contractual fee waiver and expense reimbursement agreement with the Advisor through October 28, 2020 only. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example - Class A & P Prospectus - UBS All China Equity Fund - USD ($)	1 year	3 years
Class A	680	1,012
Class P	112	412

Portfolio turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. Because the Fund had not yet commenced operations as of the date of this prospectus, it does not have a portfolio turnover rate to provide.

Principal strategies

Principal investments

The Advisor seeks to achieve the Fund's investment objective by investing, under normal circumstances, at least 80% of the Fund's net assets (plus borrowings for investment purposes, if any) in a portfolio of equity securities of companies economically tied to China, and in other instruments that have economic characteristics similar to such securities. For this purpose, China includes the People's Republic of China ("PRC") and Hong Kong. A security will be considered to be economically tied to China if it: (i) is issued or guaranteed by a government of China or any of its agencies, political subdivisions or instrumentalities; (ii) has its primary trading market in China; (iii) is issued by an entity organized under the laws of, derives at least 50% of its revenues from, or has at least 50% of its assets in China; (iv) is included in an index representative of China; or (v) is exposed to the economic fortunes and risks of China.

Equity securities may include common stocks; preferred stocks; equity securities of real estate investment trusts ("REITs"); shares of other investment companies, including exchange-traded funds ("ETFs"); depositary receipts; and derivative instruments related to equity securities, including equity participation notes, options and futures on individual securities and indexes. The Fund's investments may include investments in securities of companies listed on exchanges located in and outside of the PRC, including but not limited to the Hong Kong Stock Exchange, Taiwan Stock Exchange, Singapore Exchange, the New York Stock Exchange, and London Stock Exchange. The Fund's investments also include China A-shares. China A-shares are equity securities issued by companies incorporated in mainland China and are denominated and traded in renminbi ("RMB") on the Shenzhen and Shanghai Stock Exchanges through the Shanghai-Hong Kong Stock Connect program and the Shenzhen-Hong Kong Stock Connect program (collectively, "Stock Connect").

The Fund may invest in companies of any size. The Fund is a non-diversified fund, which means that the Fund may invest more of its assets in a smaller number of issuers than a diversified investment company.

The Advisor believes that discrepancies between market price and fair value arise from market behavior and market structure, and these discrepancies provide opportunities to outperform the market. To take advantage of these opportunities, the Advisor seeks to identify upcoming industry leaders in key secular growth sectors early in the company's lifecycle and when the company's share price trades far below our estimate of the firm's fair value.

The Advisor adopts a benchmark agnostic approach (meaning that the Advisor selects companies without the benchmark by which the Fund measures performance (the MSCI All China Index) being determinative), and the Fund may have a wider deviation from the benchmark than other funds. This is expected to enable the Advisor to identify non-benchmark companies with stronger long-term growth potential than might otherwise be the case.

The Fund may, but is not required to, use exchange-traded or over-the-counter derivative instruments for risk management purposes or as part of the Fund's investment strategies. Generally, derivatives are financial contracts whose value depends upon, or is derived from, the value of an underlying asset, reference rate, index or other market factor and may relate to stocks, bonds, interest rates, credit, currencies or currency exchange rates, commodities and related indexes. The derivatives in which the Fund may invest include options (including options on securities, indices, futures, forwards, and swap agreements), futures, forward currency agreements, swap agreements (including interest rate, total return and currency) and equity participation notes and equity linked notes. All of these derivatives may be used for risk management purposes to manage or adjust the risk profile of the Fund. Futures on currencies and forward currency agreements may also be used to hedge against a specific currency. Further, the Fund may acquire and sell forward foreign currency exchange contracts in order to attempt to protect against uncertainty in the level of future foreign currency exchange rates in connection with the settlement of securities. In addition, all of the derivative instruments listed above may be used for investment (non-hedging) purposes to earn income; to enhance returns; to replace more traditional direct investments (except for forward currency agreements); to obtain exposure to certain markets; or to establish net short positions for individual currencies (except for equity participation notes).

Management process

The investment process for the All China strategy is driven by bottom-up proprietary research. As a starting point, the investment universe includes all investable quoted equities domiciled in China and/or of issuers generating the majority of their income in China. The investment team is expected to exclude companies exhibiting what we view as unsustainable business models, poor corporate governance practices, and negative industry dynamics. In order to form a qualitative assessment of a company, the Advisor scores companies based on a set of questions covering three areas:

1. Industry Structure and Company's Competitiveness

2. Trends & Profitability: Trends and Sustainability

3. Governance, disclosure, environmental and social practices

The Advisor further conducts extensive valuation analysis incorporating company/industry fundamentals, future operations, and cash generation. Peer comparisons and valuation bands are also studied based on historical and forward looking financials.

The Advisor seeks to construct a "best ideas," concentrated, high-conviction portfolio. The companies would be selected based on the attractiveness of their valuations, top down macro factors, and a conviction that the investment thesis is likely to be realized. Positions would be assigned weights based on the investment parameters for the strategy and the portfolio manager's conviction in the investment thesis. The Advisor aims to construct a portfolio diversified across many sectors with no single stock position being greater than 10% of the portfolio.

Main risks

All investments carry a certain amount of risk, and the Fund cannot guarantee that it will achieve its investment objective. You may lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Below are some of the specific risks of investing in the Fund.

Foreign investing risk: The value of the Fund's investments in foreign securities may fall due to adverse political, social and economic developments abroad and due to decreases in foreign currency values relative to the US dollar. Investments in foreign government bonds involve special risks because the Fund may have limited legal recourse in the event of default. Also, foreign securities are sometimes less liquid and more difficult to sell and to value than securities of US issuers. These risks are greater for investments in emerging market issuers.

Emerging market risk: There are additional risks inherent in investing in less developed countries that are applicable to the Fund. Compared to the United States and other developed countries, investments in emerging market issuers may decline in value because of unfavorable foreign government actions, greater risks of political instability or the absence of accurate information about emerging market issuers. Further, emerging countries may have economies based on only a few industries and securities markets that trade only a small number of securities and employ settlement procedures different from those used in the United States. Prices on these exchanges tend to be volatile and, in the past, securities in these countries have offered greater potential for gain (as well as loss) than securities of companies located in developed countries. Further, investments by foreign investors are subject to a variety of restrictions in many emerging countries. Countries such as those in which the Fund may invest may experience high rates of inflation, high interest rates, exchange rate fluctuations or currency depreciation, large amounts of external debt, balance of payments and trade difficulties and extreme poverty and unemployment.

China risk: There are special risks associated with investments in China, Hong Kong and Taiwan, including exposure to currency fluctuations, less liquidity, expropriation, confiscatory taxation, nationalization and exchange control regulations (including currency blockage). Inflation and rapid fluctuations in inflation and interest rates have had, and may continue to have, negative effects on the economy and securities markets of China, Hong Kong and Taiwan. In addition, investments in Taiwan could be adversely affected by its political and economic relationship with China. Certain securities issued by companies located or operating in China, such as China A-shares, are subject to trading restrictions, quota limitations and less market liquidity. Reduction in spending on Chinese products and services, institution of additional tariffs or other trade barriers, including as a result of heightened trade tensions between China and the United States, or a downturn in any of the economies of China's key trading partners may have an adverse impact on the Chinese economy.

Additionally, developing countries, such as China, may subject the Fund's investments to a number of tax rules, and the application of many of those rules may be uncertain. Changes in applicable Chinese tax law could reduce the after-tax profits of the Fund, directly or indirectly, including by reducing the after-tax profits of companies in China in which the Fund invests. Uncertainties in Chinese tax rules could result in unexpected tax liabilities for the Fund.

China A-shares risk: China A-shares are subject to a number of restrictions imposed by Chinese securities regulations and listing rules. Investments by foreign investors in A-shares are subject to various restrictions, regulations and limits. The A-share market is volatile with a risk of suspension of trading in a particular security or multiple securities or government intervention. The A-shares market can have a higher propensity for trading suspensions than many other global equity markets. Trading suspensions could lead to greater market execution risk, valuation risks, liquidity risks, and costs for the Fund.

Furthermore, any changes in laws, regulations and policies of the China A-shares market or rules in relation to Stock Connect may affect China A-share prices. These risks are heightened by the developing state of the PRC's investment and banking systems in general.

Per a circular (Caishui [2014] 79), the Fund is expected to be temporarily exempt from the Chinese withholding tax ("WHT") on capital gains on trading in A-shares. There is no indication as to how long the temporary exemption will remain in effect. Accordingly, the Fund may be subject to such taxes in the future. If the Fund expects such WHT on trading in A-shares to be imposed, it reserves the right to establish a reserve for such tax, although it currently does not do so. If the Fund establishes such a reserve but is not ultimately subject to the tax, shareholders who redeemed or sold their shares while the reserve was in place will effectively bear the tax and may not benefit from the later release, if any, of the reserve. Conversely, if the Fund does not establish such a reserve but ultimately is subject to the tax, shareholders who redeemed or sold their shares prior to the tax being withheld, reserved or paid will have effectively avoided the tax, even if they benefited from the trading that precipitated the Fund's payment of it. Investors should note that such provision may be excessive or inadequate to meet actual WHT liabilities (which could include interest and penalties) on the Fund's investments. As a result, investors may be advantaged or disadvantaged depending on the final rules of the relevant PRC tax authorities.

Stock Connect investing risk: Investing in A-shares through Stock Connect is subject to trading, clearance, settlement, and other procedures, which could pose risks to the Fund. Trading through the Stock Connect program is subject to daily quotas that limit the maximum daily net purchases on any particular day, each of which may restrict or preclude the Fund's ability to invest in A-shares through the Stock Connect program. A primary feature of the Stock Connect program is the application of the home market's laws and rules applicable to investors in A-shares. Therefore, the Fund's investments in Stock Connect A-shares are generally subject to PRC securities regulations and listing rules, among other restrictions. The Shanghai and Shenzhen markets may be open at a time when the Stock Connect Program is not trading, with the result that prices of China A-shares may fluctuate at times when the Fund is unable to add to or exit its position.

Offshore RMB risk: There is no assurance that there will always be sufficient amounts of RMB (i.e., Chinese currency) available for the Fund to remain fully invested in Chinese equities. The Chinese government heavily regulates the domestic exchange of foreign currencies and RMB exchange rates in China, which may adversely affect the operations and financial results of the Fund's investments in China.

Geographic concentration risk: The risk that if the Fund has most of its investments in a single country or region, its portfolio will be more susceptible to factors adversely affecting issuers located in that country or region than would a more geographically diverse portfolio of securities.

Liquidity risk: The risk that investments cannot be readily sold at the desired time or price, and the Fund may have to accept a lower price or may not be able to sell the security at all. An inability to sell securities can adversely affect the Fund's value or prevent the Fund from taking advantage of other investment opportunities. Liquid portfolio investments may become illiquid or less liquid after purchase by the Fund due to low trading volume, adverse investor perceptions and/or other market developments. In recent years, the number and capacity of dealers that make markets in fixed income securities has decreased. Consequently, the decline in dealers engaging in market making trading activities may increase liquidity risk, which can be more pronounced in periods of market turmoil. Liquidity risk may be magnified in a rising interest rate environment or when investor redemptions from fixed income funds may be higher than normal, causing increased supply in the market due to selling activity. Liquidity risk includes the risk that the Fund will experience significant net redemptions at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio securities at a material loss.

Small- and mid-capitalization risk: The risk that securities of smaller capitalization companies tend to be more volatile and less liquid than securities of larger capitalization companies. This can have a disproportionate effect on the market price of smaller capitalization companies and affect the Fund's ability to purchase or sell these securities. In general, smaller capitalization companies are more vulnerable than larger companies to adverse business or economic developments, and they may have more limited resources.

Derivatives risk: The value of "derivatives"—so called because their value "derives" from the value of an underlying asset, reference rate or index—may rise or fall more rapidly than other investments. It is possible for the Fund to lose more than the amount it invested in the derivative. The risks of investing in derivative instruments also include market risk, management risk, counterparty risk (which is the risk that a counterparty to a derivative contract is unable or unwilling to meet its financial obligations) and the risk that changes in the value of a derivative may not correlate perfectly with the underlying asset, rate, index or overall market security. In addition, many types of swaps and other non-exchange traded derivatives may be subject to liquidity risk, credit risk and mispricing or valuation complexity. These derivatives risks are different from, and may be greater than, the risks associated with investing directly in securities and other instruments.

Real estate securities and REITs risk: The risk that the Fund's performance will be affected by adverse developments in the real estate industry. Real estate values may be affected by a variety of factors, including: local, national or global economic conditions; changes in zoning or other property-related laws; environmental regulations; interest rates; tax and insurance considerations; overbuilding; property taxes and operating expenses; or declining values in a neighborhood. Similarly, a REIT's performance depends on the types, values, locations and management of the properties it owns. In addition, a REIT may be more susceptible to adverse developments affecting a single project or market segment than a more diversified investment. Loss of status as a qualified REIT under the US federal tax laws could adversely affect the value of a particular REIT or the market for REITs as a whole.

Investing in other funds risk: The Fund's investment performance is affected by the investment performance of the underlying funds in which the Fund may invest. Through its investment in the underlying funds, the Fund is subject to the risks of the underlying funds' investments and their expenses.

Investing in ETFs risk: The Fund's investment in ETFs may subject the Fund to additional risks than if the Fund would have invested directly in the ETF's underlying securities. These risks include the possibility that an ETF may experience a lack of liquidity that can result in greater volatility than its underlying securities; an ETF may trade at a premium or discount to its net asset value; or an ETF may not replicate exactly the performance of the benchmark index it seeks to track. In addition, investing in an ETF may also be more costly than if a Fund had owned the underlying securities directly. The Fund, and indirectly, shareholders of the Fund, bear a proportionate share of the ETF's expenses, which include management and advisory fees and other expenses. In addition, the Fund will pay brokerage commissions in connection with the purchase and sale of shares of the ETF.

Leverage risk associated with financial instruments: The use of financial instruments to increase potential returns, including derivatives used for investment (non-hedging) purposes, may cause the Fund to be more volatile than if it had not been leveraged. The use of leverage may also accelerate the velocity of losses and can result in losses to the Fund that exceed the amount originally invested.

Non-diversification risk: The Fund is a non-diversified investment company, which means that the Fund may invest more of its assets in a smaller number of issuers than a diversified investment company. As a non-diversified fund, the Fund's share price may be more volatile, and the Fund has a greater potential to realize losses upon the occurrence of adverse events affecting a particular issuer.

Market risk: The market value of the Fund's investments may fluctuate, sometimes rapidly or unpredictably, as the stock and bond markets fluctuate. Market risk may affect a single issuer, industry, or sector of the economy, or it may affect the market as a whole.

Management risk: The risk that the investment strategies, techniques and risk analyses employed by the Advisor may not produce the desired results.

[2] 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, extraordinary expenses and dividend expense and security loan fees for securities sold short), through the period ending October 28, 2020, 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 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.
