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 redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same.*

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example		1 year	3 years	5 years	10 years

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. During the most recent fiscal year, the fund's portfolio turnover rate was 117% of the average value of its portfolio.

Principal strategies

Principal investments

The fund seeks to achieve its objective by investing primarily in real estate investment trusts ("REITs") and other real-estate related securities. Under normal market circumstances, the fund invests at least 80% of its net assets (plus the amount of any borrowing for investment purposes) in securities of companies in the real estate industry, which may include common shares, preferred shares, initial public offerings ("IPOs") and units of beneficial interest in real estate companies (inclusive of REITs). The fund invests in such securities of companies with varying market capitalizations.

The fund will consider real estate securities to be those securities issued by companies principally engaged in the real estate industry, defined to mean those companies which (1) derive at least 50% of their revenues from the ownership, operation, development, construction, financing, management or sale of commercial, industrial or residential real estate and similar activities, or (2) invest at least 50% of their assets in such real estate.

The fund may invest in the securities of issuers located in a number of different countries throughout the world. Under normal market circumstances, the fund will maintain exposure to real estate related securities of issuers in the US and in at least three countries outside the US. The amount invested outside the US may vary, and at any given time, the fund may have a significant exposure to non-US securities depending upon an investment advisor's investment decisions.

Management process

The fund employs a "manager of managers" structure. UBS Asset Management (Americas) Inc. ("UBS AM"), the fund's manager and primary provider of investment advisory services, has the ultimate authority, subject to oversight by the fund's board, to oversee the fund's subadvisor(s) and recommend their hiring, termination and replacement, and to allocate assets among the fund's subadvisor(s). The relative value of each subadvisor's share of the fund's assets may change over time.

UBS AM's investment process begins with subadvisor selection. UBS AM's portfolio management team constructs a list of potential subadvisors based on information primarily from internal sources and the team's collective knowledge of the industry, but also supplemented by external sources. The team then focuses its research on that list to identify a small number of the most attractive candidates. This research includes analyzing the portfolio holdings and/or positioning of a subadvisor's investment strategy to understand whether the allocation of risk and the drivers of alpha are consistent with the subadvisor's investment philosophy and stated

strengths. The most attractive sub-set of those subadvisors is then selected for in-depth, on-site due diligence meetings with representatives from the investment, operations and compliance groups within UBS AM. The due diligence information is then synthesized to select the most attractive candidate(s) for the fund, subject to the board's approval.

In managing the fund and overseeing the fund's subadvisor(s), UBS AM views its research process as an ongoing one, as the team continually seeks to confirm a subadvisor's investment thesis over the appropriate investment horizon. In general, UBS AM leverages its research and market knowledge to construct funds with exposure to various subadvisors that are expected, in combination, to produce the desired overall fund characteristics. UBS AM's ongoing monitoring and risk management process incorporates daily, weekly, monthly, quarterly and annual responsibilities designed to monitor the drivers of fund risk and performance at the subadvisor level and at the overall fund level. Through this process, UBS AM may adjust a fund's positioning by altering its allocation weights across subadvisors within the fund and/or by changing the specific subadvisors within the fund.

The subadvisor utilizes a strategy that involves focusing on investments in equity REITs as well as similar entities formed under the laws of non-US countries, and the subadvisor may also invest in mortgage REITs, hybrid REITs and other US and foreign real estate-related investments, including emerging market real estate-related investments.

Principal 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. The principal risks presented by an investment in the fund are:

Equity risk: Stocks and other equity securities, and securities convertible into stocks, generally fluctuate in value more than bonds. Preferred stocks in which the fund may invest are also sensitive to interest rate changes. The rights of preferred stocks on the distribution of a company's assets in the event of a liquidation are generally subordinate to the rights associated with a company's debt securities. The fund could lose all of its investment in a company's stock.

Real estate industry risk: An investment in the fund is subject to certain risks associated with the direct ownership of real estate and with the real estate industry in

general, including possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage financing; variations in rental income, neighborhood values or the appeal of property to tenants; interest rates; over-building; extended vacancies of properties; increases in competition, property taxes and operating expenses; and changes in zoning laws. The values of securities of companies in the real estate industry, which is sensitive to economic downturns, may go through cycles of relative under-performance and out-performance in comparison to equity securities markets in general.

Real estate investment trust risk: The performance of equity and mortgage REITs depends on how well each REIT manages its properties. Equity REITs, which invest directly in real estate properties and property developers, may be affected by any changes in the value of the underlying property owned by the trusts. Mortgage REITs, which specialize in lending money to developers of properties, may be affected by the quality of any credit extended.

Sector risk: Because the fund may invest a significant portion of its assets in the stocks of companies in particular economic sectors, economic changes adversely affecting such a sector may have more of an impact on the fund's performance than another fund having a broader range of investments.

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.

Foreign currency risk: The value of non-US dollar denominated securities held by the fund may be affected by changes in exchange rates or control regulations. If a local currency declines against the US dollar, the value of the holding decreases in US dollar terms. In addition, the fund may be exposed to losses if its other foreign currency positions (e.g., options, forward commitments) move against it.

Foreign custody risk: The fund may hold foreign securities and cash with foreign banks, agents and securities depositories. Such foreign banks or securities depositories may be subject to limited regulatory oversight. The laws of certain countries also may limit the fund's ability to recover its assets if a foreign bank or depository enters into bankruptcy.

Limited capitalization risk: The risk that securities of smaller capitalization companies tend to be more volatile and less liquid than securities of larger capital-

ization 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.

Leverage risk associated with financial instruments: The use of financial instruments to increase potential returns, including derivatives and other types of transactions used for investment (non-hedging) purposes (as applicable), 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.

Market risk: The risk that 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. Moreover, changing market, economic, political and social conditions in one country or geographic region could adversely impact market, economic, political and social conditions in other countries or regions.

Liquidity risk: Certain of the fund's investments may present liquidity risk. Liquidity risk involves 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.

Initial public offerings risk: The purchase of shares issued in IPOs may expose the fund to the risks associated with issuers that have no operating history as public companies, as well as to the risks associated with the sectors of the market in which the issuer operates. The market for IPO shares may be volatile, and share prices

of newly-public companies may fluctuate significantly over a short period of time.

Interest rate risk: An increase in prevailing interest rates typically causes the value of fixed income securities to fall. Changes in interest rates will likely affect the value of longer-duration fixed income securities more than shorter-duration securities and higher quality securities more than lower quality securities. When interest rates are falling, some fixed income securities provide that the issuer may repay them earlier than the maturity date, and if this occurs the fund may have to reinvest these repayments at lower interest rates. The fund may face a heightened level of interest rate risk due to certain changes in monetary policy, such as certain types of interest rate changes by the Federal Reserve. During periods when interest rates are low or there are negative interest rates, the fund's performance may be negatively impacted, and the fund may experience increased volatility of its net asset value per share.

Multi-manager risk: The investment styles and strategies of the fund's subadvisors may not complement each other as expected by the fund's manager. The same security may be held by different subadvisors, or may be acquired by one subadvisor while another subadvisor of the fund decides to sell the same security. Subadvisors may have different views on the market causing them to make different investment decisions. For example, a subadvisor may determine that it is appropriate to take a temporary defensive position in short-term cash instruments at a time when another subadvisor deems it appropriate to maintain or increase market exposure. Because each subadvisor independently places trades for the fund, the fund may incur higher brokerage costs than would be the case if the fund only had one subadvisor. In addition, UBS AM may be subject to potential conflicts of interests in allocating fund assets because it pays different fees to the subadvisors which could impact its revenues.

Management risk: The risk that the investment strategies, techniques and risk analyses employed by UBS AM and/or a subadvisor may not produce the desired results.

Performance

Risk/return bar chart and table

The performance information that follows shows the fund's performance information in a bar chart and an average annual total returns table. The bar chart does not reflect any program fee or similar fee charged by advisory programs through which Class P shares of the fund may be held; if it did, the total returns shown would be lower. The information provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual total returns compare with those of a broad measure of mar-

ket performance. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. This may be particularly true given that other subadvisors were responsible for managing portions of the fund's assets during previous periods. Massachusetts Financial Services Company, doing business as MFS Investment Management ("MFS") assumed day-to-day management of a separate portion of the fund's assets on March 11, 2021. Updated performance for the fund is available at www.ubs.com/us-mutualfundperformance.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold fund shares through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts.

[1] Class P shares held through the PACE Select Advisors Program are subject to a maximum Program fee of 2.50%. Class P shares held through other advisory programs also may be subject to a program fee.

[1] "Other expenses" include "Acquired fund fees and expenses," which were less than 0.01% of the average net assets of the fund. Since the "Acquired fund fees and expenses" are not directly borne by the fund, they are not reflected in the fund's financial statements, and therefore the amounts listed in "Total annual fund operating expenses" and "Total annual fund operating expenses after fee waiver and/or expense reimbursements" may differ from those presented in the financial highlights.

[2] The fund and UBS Asset Management (Americas) Inc. ("UBS AM") have entered into a written fee waiver/expense reimbursement agreement pursuant to which UBS AM is contractually obligated to waive its management fees and/or reimburse expenses so that the fund's ordinary total operating expenses through November 30, 2022 (excluding, as applicable, (i) dividend expense, borrowing costs, and interest expense relating to short sales, and (ii) expenses attributable to investment in other investment companies, interest, taxes, brokerage commis-sions, expenses related to shareholders' meetings, and extraordinary expenses) would not exceed 1.20% for Class P. The fund has agreed to repay UBS AM for any waived fees/reimbursed expenses to the extent that it can do so over the following three fiscal years without causing the class expenses in any of those three years to exceed this expense cap and that UBS AM has not waived the right to do so. The fee waiver/expense reimbursement agreement may be terminated by the fund's board at any time and also will terminate automatically upon the expiration or termination of the fund's advisory contract with UBS AM. Upon termination of the agreement, however, UBS AM's three year recoupment rights will survive.

[1] Except that the expenses reflect the effects of the fund's fee waiver/expense reimbursement agreement for the first year only.

[1] 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 and Class P shares held through certain brokerage platforms may be subject to commissions or other fees, which, if included, would have reduced performance.
