The Fund seeks to maximize total return, consisting of capital appreciation and current income.

These tables describe the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. Shares of Class P2 are available for purchase on behalf of clients of a fee-based program or certain other advisory programs in which UBS Asset Management (Americas) LLC, the Fund’s investment advisor and administrator (“UBS AM (Americas)” or the “Advisor”) exercises investment discretion. Clients pay a wrap fee or a similar advisory fee to participate in such programs. Shares of Class P2 are also available for purchase on behalf of institutional clients with which the Advisor or its affiliates has signed a separate investment management agreement, pursuant to which such clients pay an advisory fee.

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 expenses of the Fund that would result from the contractual fee waiver and expense reimbursement agreement with the Advisor for the first year only. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

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 28% of the average value of its portfolio.

Risk/return bar chart and table

The performance information that follows shows the Fund’s Class P2 performance information in a bar chart and an average annual total returns table.

The information provides some indication of the risks of investing in the Fund by showing changes in the Fund’s performance and by showing how the Fund’s average annual total returns compare with those of a broad measure of market performance. The index reflects no deduction for fees, expenses or taxes but is net of dividend tax withholding. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance for the Fund is available at www.ubs.com/us/en/assetmanagement/funds/mutual-fund-performance. Class P2 shares do not bear initial or contingent deferred sales charges or ongoing 12b‑1 service and distribution fees, but Class P2 shares held through advisory programs may be subject to a program fee, advisory fee or other fees, which, if included, would have reduced performance.

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. After-tax returns for other classes will vary from the Class P2 shares’ after-tax returns shown.

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.

Dividend paying stock risk: Issuers that have paid regular dividends or distributions to shareholders may not continue to do so in the future. An issuer may reduce or eliminate future dividends or distributions at any time and for any reason. The value of a security of an issuer that has paid dividends in the past may decrease if the issuer reduces or eliminates future payments to its shareholders. If the dividends or distributions received by the Fund decreases, the Fund may have less income to distribute to the Fund’s shareholders. In addition, common stocks with higher dividend yields can be sensitive to interest rate movements: when interest rates rise, the prices of these stocks may tend to fall. Conversely, the prices of higher yielding stocks may tend to rise when interest rates fall. Interest rate chang‐

es can be sudden and unpredictable and are influenced by a number of factors including government policy, monetary policy, inflation expectations, perceptions of risk, and supply and demand of bonds.

Information technology sector risk: The Fund’s performance may be particularly affected by developments affecting the information technology sector as a result of significant investments in such sector. Information technology companies may face rapid technological change, short product cycles, intense competition, changing customer preferences, and substantial research and development costs. A company’s products or services may become obsolete or fail to gain market acceptance, and its financial results may depend on a limited number of products, customers, or key personnel. These companies may also be adversely affected by cybersecurity incidents, service disruptions, data-privacy requirements, changes in government regulation, and the failure to obtain (or delays in obtaining) financing or regulatory approvals. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights and disputes over intellectual property rights may adversely affect the profitability of these companies.

The market prices of information technology securities may be especially volatile, and adverse developments affecting the information technology sector could cause the Fund’s shares to decline in value.

Model and data risk: The Advisor may employ a complex strategy using proprietary quantitative models in selecting investments for the Fund. Investments selected using these models may perform differently than expected as a result of the factors used in the models, the weight placed on each factor, changes from the factors’ historical trends, and technical issues in the con‐

struction and implementation of the models (including, for example, data problems, problems with data supplied by third parties, software issues, or other types of errors). There is no guarantee that the Advisor’s quantitative models will perform as expected or result in effective investment decisions for the Fund.

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. The performance of 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. REITs expose investors in the Fund to the risks of owning real estate directly, including fluctuations in the value of underlying properties, defaults by borrowers or tenants, changes in interest rates and risks related to general or local economic conditions. 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.

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 (such as expropriation or nationalization), greater risks of political and civil

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. Issuers may not be subject to uniform accounting, auditing and financial reporting standards and there may be less publicly available financial and other information about such issuers, comparable to US issuers. 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 transaction costs, possible foreign controls on investment, less stringent investor protections, high rates of inflation or deflation, 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. Additionally, the Fund may have substantial difficulties exercising its legal rights or enforcing a counterparty’s or issuer’s legal obligations in certain jurisdictions outside of the United States, and it may be more difficult for investors or for US regulators to bring litigation or enforcement actions against such issuers, which can increase the risks of loss.

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. When using derivatives for hedging purposes, the Fund’s overall returns may be reduced if the hedged investment experiences a favorable price movement. In addition, if the Fund has insufficient cash to meet daily variation margin or payment requirements, it may have to sell securities from its portfolio at a time when it may be disadvantageous to do so. The risks of investing in derivative instruments also include market, leverage, operational, legal, and management risks. In addition, nonexchange traded derivatives may be subject to liquidity risk, counterparty risk (which is the risk that a counterparty to a derivative contract is unable or unwilling to meet its financial obligations), credit risk

and mispricing or valuation complexity. Derivatives also involve the risk that changes in the value of a derivative may not correlate as anticipated with the underlying asset, rate, index or overall securities markets, thereby reducing their effectiveness. These derivatives risks are different from, and may be greater than, the risks associated with investing directly in securities and other instruments.
