The funds and their investment policies

Except where noted, the investment objective and policies of each fund may be changed by the Trust's board without shareholder approval. As with other mutual funds, there is no assurance that a fund will achieve its investment objective.

As described further below, each fund (other than PACE Alternative Strategies Investments) will invest at least 80% of its net assets (plus the amount of any borrowing for investment purposes) in the type of investment suggested by its name.

The funds have not repeated the above noted parenthetical regarding borrowings each time a percentage test is recited below; however, the funds will interpret these name-related policies as if the following phrase appeared immediately after the words "net assets": "(plus the amount of any borrowing for investment purposes)." If subsequent to an investment, a fund's 80% policy is no longer met (e.g., a fund receives a very large influx of cash to invest from new shareholders), then, under normal circumstances, the fund's future investments will be made in a manner that will bring the fund's investments back in line with the 80% threshold.

UBS Government Money Market Investments Fund has an investment objective of current income consistent with preservation of capital and liquidity. The fund is a money market fund and seeks to maintain a stable price of $1.00 per share. Under normal circumstances, the fund invests at least 80% of its net assets in US government securities, including government securities subject to repurchase agreements. The fund's 80% policy is a "non-fundamental" policy. This means that this investment policy may be changed by the board without shareholder approval. However, the fund has also adopted a policy to provide its shareholders with at least 60 days' prior written notice of any change to the 80% investment policy. The fund may also invest in the securities of other investment companies that invest in these instruments. The fund invests in high quality money market instruments that have, or are deemed to have, remaining maturities of 13 months or less. Money market instruments generally are short-term debt obligations and similar securities. They also may include longer-term bonds that have variable interest rates or other special features that give them the financial characteristics of short-term debt. The fund may purchase participation interests in any of the securities in which it is permitted to invest. Participation interests are pro rata interests in securities held by others. The fund maintains a dollar-weighted average portfolio maturity of 60 days or less; the fund maintains a dollar-weighted average life for its portfolio of 120 days or less.

The board has determined that the fund will operate as a "government money market fund" under Rule 2a-7 of the Investment Company Act of 1940, as amended ("Investment Company Act"). Therefore, in addition to the 80% policy referenced above, the fund has adopted a policy to invest 99.5% or more of its total assets in cash, government securities, and/or repurchase agreements that are collateralized fully (i.e., collateralized with cash and/or government securities). As a "government money market fund" under Rule 2a-7, the fund (1) is permitted to use the amortized cost method of valuation to seek to maintain a $1.00 share price, and (2) is not subject to a liquidity fee on fund redemptions which might apply to other types of funds under certain circumstances. (In conformance with Rule 2a-7, the board has reserved its ability to change this policy with respect to liquidity fees, but such change would only become effective after shareholders were provided with specific advance notice of a change in the fund's policy and have the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.)

UBS Government Money Market Investments Fund may purchase only those obligations that UBS AM determines, pursuant to procedures adopted by the board, present minimal credit risks as defined in Rule 2a-7 under the Investment Company Act.

UBS Government Money Market Investments Fund may purchase variable and floating rate securities with remaining maturities in excess of 397 calendar days issued by US government agencies or instrumentalities or guaranteed


3


by the US government. The yields on these securities are adjusted in relation to changes in specific rates, such as the prime rate, and different securities may have different adjustment rates. Certain of these obligations carry a demand feature that gives the fund the right to tender them back to a specified party, usually the issuer or a remarketing agent, prior to maturity. The fund's investment in these securities must comply with conditions established by the US Securities and Exchange Commission ("SEC") under which they may be considered to have remaining maturities of 397 calendar days or less. The fund will purchase variable and floating rate securities of non-US government issuers that have remaining maturities of more than 397 calendar days only if the securities are subject to a demand feature exercisable within 397 calendar days or less and otherwise consistent with the fund's investment objective and policies. See "The funds' investments, related risks and limitations—Credit and liquidity enhancements."

Generally, UBS Government Money Market Investments Fund may exercise demand features (1) upon a default under the terms of the underlying security, (2) to maintain its portfolio in accordance with its investment objective and policies or applicable legal or regulatory requirements or (3) as needed to provide liquidity to the fund in order to meet redemption requests. The ability of a bank or other financial institutional to fulfill its obligations under a letter of credit, guarantee or other liquidity arrangement might be affected by possible financial difficulties of its borrowers, adverse interest rate or economic conditions, regulatory limitations or other factors. The interest rate on floating rate or variable rate securities ordinarily is readjusted on the basis of the prime rate of the bank that originated the financing or some other index or published rate, such as the 90-day US Treasury bill rate, or is otherwise reset to reflect market rates of interest. Generally, these interest rate adjustments cause the market value of floating rate and variable rate securities to fluctuate less than the market value of fixed rate securities.

UBS Government Money Market Investments Fund will not acquire any illiquid investment (as defined below) if, immediately after the acquisition, the fund would have invested more than 5% of its total assets in illiquid investments. The fund also will comply with the daily and weekly liquidity requirements set forth in Rule 2a-7 of the Investment Company Act and, as such, must maintain a portion of its assets in cash and securities that can readily be converted into cash, which may have a negative effect on yield. The fund may purchase securities on a when-issued or delayed delivery basis in accordance with Rule 18f-4 under the Investment Company Act ("Rule 18f-4"). The fund may lend its portfolio securities to qualified broker-dealers or institutional investors in an amount up to 331/3% of its total assets. The fund may borrow money from banks and through reverse repurchase agreements for temporary or emergency purposes, but not in excess of 10% of its total assets. The costs associated with borrowing may reduce the fund's net income. See "The funds' investments, related risks and limitations—Investment limitations of the funds" for more information regarding borrowings. The fund may invest in the securities of other investment companies, including money market funds advised by UBS AM.

PACE Mortgage-Backed Securities Fixed Income Investments has an investment objective of current income. Pacific Investment Management Company LLC ("PIMCO") serves as the fund's subadvisor. The fund invests in bonds of varying maturities but normally limits its portfolio "duration" to within +/- 50% of the effective duration of the fund's benchmark index, Bloomberg US Mortgage-Backed Securities Index, as calculated by the investment advisor. Under normal circumstances, the fund invests at least 80% of its net assets (plus the amount of any borrowing for investment purposes) in a diversified portfolio of mortgage-related fixed income instruments, including mortgage-backed securities (including mortgage pass-through securities and collateralized mortgage obligations ("CMOs"), commercial mortgage-backed securities, "to be announced" (or "TBA") securities and mortgage dollar rolls). The fund may include as counting toward its 80% policy mortgage-related fixed income instruments that are represented by derivatives or by investments in securities of other investment companies that invest primarily in mortgage-related fixed income instruments.

The fund may invest up to 20% of its net assets in other fixed income instruments, including corporate bonds and asset-backed securities of private issuers. Under normal circumstances, the fund's investments will be rated at least BBB by Standard & Poor's, a division of the McGraw-Hill Companies, Inc. ("S&P"), or Moody's Investors Service, Inc. ("Moody's"), or equivalently rated by another nationally recognized statistical rating organization or, if unrated, determined by the investment advisor to be of comparable quality, and a maximum of 5% of the fund's net assets

may be invested in non-investment grade securities. The fund may invest in bonds that are assigned comparable ratings by another nationally recognized statistical rating organization (collectively, with Moody's and S&P, "Rating Agencies") and unrated bonds that its investment advisor determines are of comparable quality to rated securities in which the fund may invest. The fund may invest up to 10% of its net assets in Yankee and Brady bonds.

PACE Mortgage-Backed Securities Fixed Income Investments may invest in certain zero coupon securities that are US Treasury notes and bonds that have been stripped of their unmatured interest coupon receipts. The SEC staff currently takes the position that "stripped" US government securities that are not issued through the US Treasury are not US government securities. The fund may not invest more than 5% of its net assets in any combination of interest-only, principal-only and inverse floating rate securities, including those that are not mortgage- or asset-backed securities. The fund may invest up to 10% of its net assets in municipal bonds that are rated at least A by Moody's or S&P or assigned a comparable rating by another Rating Agency (or are unrated but deemed to be of comparable quality).

The fund also may engage in short selling with respect to securities issued by the US Treasury and certain "to be announced" or "TBA" securities coupon trades. TBA securities are mortgage-backed securities that usually are traded on a forward commitment basis with an approximate principal amount and no defined maturity date, issued or guaranteed by US government agencies and instrumentalities. The actual principal amount and maturity date of the securities are determined upon settlement when the specific mortgage pools are assigned. The fund limits the TBA securities that it sells short to those issued by the Governmental National Mortgage Association, the Federal National Mortgage Association and the Federal Home Loan Mortgage Corporation. The fund will not make short sales of securities or maintain a short position if doing so could create liabilities or require collateral deposits and segregation of assets of more than one-third of the value of its total assets.

PACE Mortgage-Backed Securities Fixed Income Investments may invest up to 15% of its net assets in illiquid investments (as defined below).

The fund may lend its portfolio securities to qualified broker-dealers or institutional investors in an amount up to 331/3% of its total assets. The fund may borrow money from banks and through reverse repurchase agreements for temporary or emergency purposes, but not in excess of 10% of its total assets. The costs associated with borrowing may reduce the fund's net income. See "The funds' investments, related risks and limitations—Investment limitations of the funds" for more information regarding borrowings. The fund may invest in structured foreign investments. The fund may invest in securities of other investment companies, including closed-end funds that invest in foreign markets, and may sell securities short both "against the box" or without owning the security sold short.

PACE International Emerging Markets Equity Investments has an investment objective of capital appreciation. William Blair Investment Management, LLC ("William Blair"), RWC Asset Advisors (US) LLC ("Redwheel") and ARGA Investment Management, LP ("ARGA") serve as the fund's subadvisors. UBS AM, subject to board oversight, allocates the fund's assets among the subadvisors who utilize investment strategies designed to achieve capital appreciation. Under normal circumstances, the fund invests at least 80% of its net assets (plus the amount of any borrowing for investment purposes) in equity securities that are tied economically to emerging market countries, which may include equity securities issued by companies domiciled in emerging market countries. Such investments may be represented by investments in securities of other investment companies that invest primarily in equity securities that are tied economically to emerging market countries. "Domiciled," for these purposes, means companies (1) that are organized under the laws of an emerging market country, (2) for which the principal securities trading market is in an emerging market country, (3) that derive a significant proportion (at least 50%) of their revenues or profits from goods produced or sold, investments made or services performed in the respective country, or (4) that have at least 50% of their assets situated in such a country. The fund generally considers "emerging market countries" to be those countries not included in the Morgan Stanley Capital International World Index of major world economies. A subadvisor may at times determine, based on its own analysis, that an economy included in the MSCI World Index should nonetheless be considered an emerging market country, in which case, that country would constitute an emerging market country for purposes of the fund's investments. The fund normally invests in the securities of issuers from three or more emerging market countries. As of July 31, 2023, the fund was invested in over 23 separate countries. The fund may include as counting toward its 80% policy equity securities that are tied economically to emerging market countries that are represented by derivatives.

Under normal circumstances, the fund may invest up to 20% of its net assets in bonds, including US government bonds, foreign government bonds and bonds of private US and non-US issuers, including convertible bonds. The fund's investments may include Brady Bonds. The fund's investments in bonds of private issuers are rated at the time of purchase at least A by S&P or Moody's, assigned a comparable rating by another rating agency or, if unrated, determined by the investment advisor to be of comparable quality, except that up to 10% of the fund's total assets may be invested in lower quality bonds, including convertible bonds. These lower quality bonds must, at the time of purchase, be rated at least C by S&P, assigned a comparable rating by another rating agency or determined by an investment advisor to be of comparable quality.

eign investments and loan participations and assignments. These investments are generally subject to the fund's overall limitation on illiquid investments, and in no event may the fund's investments in loan participations and assignments exceed 10% of its total assets.

PACE Global Real Estate Securities Investments has an investment objective of total return. Massachusetts Financial Services Company, doing business as MFS Investment Management ("MFS") serves as the fund's subadvisor. The fund invests primarily in real estate investment trusts ("REITs") and other real-estate related securities. Under normal market conditions, the fund will invest 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. Such securities may include common shares, preferred shares, initial public offerings and units of beneficial interest in real estate companies (inclusive of REITs). 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 include as counting toward its 80% policy securities of companies in the real estate industry that are represented by derivatives, including swap agreements or futures contracts, or by investments in securities of other investment companies that invest primarily in securities of companies in the real estate industry.

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 United States and in at least three countries outside the United States. The amount invested outside the United States may vary, and at any given time, the fund may have a significant exposure to non-US securities depending upon an subadvisor's investment decisions. "Non-US securities" in this context generally means securities which are issued by a company that is organized under the laws of a country other than the United States where the principal trading market for the issuer's securities is in a country other than the United States.

The fund's other investments may include the following equity and fixed income securities and other instruments: non-investment grade bonds, government securities, asset-backed and mortgage-backed securities, credit and liquidity enhancements, original issue discount bonds (including zero coupon securities), payment-in-kind bonds, convertible bonds, warrants, auction rate and remarketed preferred stock, foreign and emerging market equity and debt securities (including Russian securities), foreign sovereign debt and structured foreign investments, currency-linked investments, repurchase agreements, reverse repurchase agreements, dollar rolls, exchange traded options, exchange-traded funds or investments in a company's initial public offering.

The fund may lend its portfolio securities to qualified broker-dealers or institutional investors in an amount up to 331/3% of its total assets. The fund may also borrow money from banks and through reverse repurchase agreements for temporary or emergency purposes, but not in excess of 10% of its total assets. The costs associated with borrowing may reduce the fund's net income. See "The funds' investments, related risks and limitations—Investment limitations of the funds" for more information regarding borrowings. The fund may invest in the securities of other investment companies and may sell securities short both "against the box" or without owning the security sold short.

The fund may implement various temporary or defensive strategies at times when its investment advisors determine that conditions in the markets make pursuing the fund's basic investment strategy inconsistent with the best interests of its shareholders. When unusual market or economic conditions occur, the fund may, for temporary defensive purposes, invest up to 100% of its total assets, or for liquidity purposes, invest up to 20% of its net assets, in investment grade fixed income securities (including short-term US government securities, investment grade

debt-instruments, money market instruments, including negotiable certificates of deposit, non-negotiable fixed time deposits, bankers' acceptances, commercial paper and floating rate notes), preferred stocks and repurchase agreements. Under normal circumstances, the fund may also hold significant amounts of its assets in cash.

PACE Alternative Strategies Investments has an investment objective of long-term capital appreciation. Allspring Global Investments, LLC ("Allspring"), Aviva Investors Americas LLC ("Aviva"), PCJ Investment Counsel Ltd. ("PCJ"), Kettle Hill Capital Management, LLC ("Kettle Hill"), DLD Asset Management, LP ("DLD"), Magnetar Asset Management LLC ("Magnetar") and Electron Capital Partners, LLC ("Electron") serve as the fund's subadvisors. UBS AM, subject to board oversight, directly manages a separate portion of the fund's assets and allocates the fund's assets among itself and the subadvisors who utilize investment strategies designed to achieve long-term capital appreciation. Aviva uses "associated persons" employed by an affiliate of Aviva, Aviva Investors Global Services Limited ("Aviva (UK)"), in its provision of investment advisory services to the fund under a "participating affiliate" arrangement. Such investment strategies are designed to have low correlation to traditional equity and fixed income asset classes. Subject to board approval, UBS AM may in the future allocate assets to additional subadvisors to employ additional strategies at any time. Such additional strategies may include, among others, fixed income arbitrage and convertible arbitrage equity strategies.

PACE Alternative Strategies Investments has a broad investment mandate that permits the fund to use an extensive range of investment strategies and to invest in a wide spectrum of equity, fixed income and derivative investments in order to pursue its investment objective. The fund invests in securities of US and non-US companies of various market capitalizations.

The fund may, but is not required to, invest extensively in derivatives, including those that provide exposure to commodities and currencies.

Under normal circumstances, the fund may invest in a number of different countries throughout the world, including the United States. The fund may invest all or a portion of its total assets in non-US securities. "Non-US securities" generally means securities that are issued by a company that is organized under the laws of a country other than the United States where the principal trading market for the issuer's securities is in a country other than the United States. Such securities may trade either within or outside the United States. The fund may also invest in the securities of companies in emerging markets, including Russia, Asia, Latin America, and other regions where the markets may not yet fully reflect the potential of the developing economies. The fund generally considers emerging market countries to be those countries that are not included in the Morgan Stanley Capital International World Index of major world economies.

PACE Alternative Strategies Investments may invest in fixed income securities including high yield bonds, US government bonds, investment grade corporate bonds and sovereign debt of non-US governmental agencies (including emerging market debt). The fund's investments may also include certain zero coupon securities that are US Treasury notes and bonds that have been stripped of their unmatured interest coupon receipts. The fund may invest up to 15% of its net assets in illiquid investments, including investments that, at the time of purchase, are in default or whose issuers are the subject of bankruptcy proceedings. Investment in these securities is highly speculative and involves significant risk. The fund may purchase these securities if a subadvisor believes that these securities have a potential for capital appreciation.

The fund may purchase securities on a when-issued or delayed delivery basis. The fund may lend its portfolio securities to qualified broker-dealers or institutional investors in an amount up to 331/3% of its total assets. The fund may also borrow money from banks and through reverse repurchase agreements for temporary or emergency purposes, but not in excess of 10% of its total assets. The costs associated with borrowing may reduce the fund's net income. See "The funds' investments, related risks and limitations—Investment limitations of the funds" for more information regarding borrowings. The fund may invest in the securities of other investment companies and may sell securities short both "against the box" or without owning the security sold short.

The fund may implement various temporary or defensive strategies at times when a subadvisor determines that conditions in the markets make pursuing the fund's basic investment strategy inconsistent with the best interests of its shareholders. When unusual market or economic conditions occur, the fund may, for temporary defensive or liquidity purposes, invest up to 100% of its total assets in securities issued or guaranteed by the US government or its agencies or instrumentalities, certificates of deposit, bankers' acceptances or other bank obligations, commercial paper, or other income securities deemed by UBS AM to be consistent with a defensive posture, or it may hold cash.

The funds' investments, related risks and limitations

The following supplements the information contained in the prospectus and above concerning the funds' investments, related risks and limitations. Except as otherwise indicated in the prospectus or SAI, the funds have established no policy limitations on their ability to use the investments or techniques discussed in these documents.

Equity securities. Equity securities include common stocks, most preferred stocks and securities that are convertible into them, including common stock purchase warrants and rights, equity interests in trusts, partnerships, joint ventures or similar enterprises and depositary receipts. Common stocks, the most familiar type, represent an equity (ownership) interest in a corporation.

Preferred stock has certain fixed income features, like a bond, but it is actually an equity security that is senior to a company's common stock. Convertible bonds may include debentures and notes that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular period of time at a specified price or formula. Some preferred stock also may be converted into or exchanged for common stock. Depositary receipts typically are issued by banks or trust companies and evidence ownership of underlying equity securities.

While past performance does not guarantee future results, common stocks historically have provided the greatest long-term growth potential in a company. However, their prices generally fluctuate more than other securities and reflect changes in a company's financial condition and in overall market and economic conditions. A company's common stock is generally a riskier investment than its fixed income securities. Preferred stocks in which a fund may invest are 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. It is possible that a fund may experience a substantial or complete loss on an individual equity investment. While this is possible with fixed income securities, it is less likely.

Bonds. Bonds are fixed or variable rate debt obligations, including bills, notes, debentures, money market instruments and similar instruments and securities. Mortgage- and asset-backed securities are types of bonds, and certain types of income-producing, non-convertible preferred stocks may be treated as bonds for investment purposes. Bonds generally are used by corporations, governments and other issuers to borrow money from investors. The issuer pays the investor a fixed or variable rate of interest and normally must repay the amount borrowed on or before maturity. Many preferred stocks and some bonds are "perpetual" in that they have no maturity date.

Bonds are subject to interest rate risk and credit risk. Interest rate risk is the risk that interest rates will rise and that, as a result, bond prices will fall, lowering the value of a fund's investments in bonds. In general, bonds having longer durations are more sensitive to interest rate changes than are bonds with shorter durations. Credit risk is the risk that an issuer may be unable or unwilling to pay interest and/or principal on the bond. Credit risk can be affected by many factors, including adverse changes in the issuer's own financial condition or in economic conditions.

While assets in bond markets have grown rapidly in recent years, the capacity for traditional dealer counterparties to engage in fixed income trading has not kept pace and in some cases has decreased. For example, primary dealer


16


inventories of corporate bonds, which provide a core indication of the ability of financial intermediaries to "make markets," are at or near historic lows in relation to market size. This reduction in market-making capacity may be a persistent change, to the extent it is resulting from broader structural changes, such as fewer proprietary trading desks at broker-dealers and increased regulatory capital requirements. Because market makers provide stability to a market through their intermediary services, the significant reduction in dealer inventories could potentially lead to decreased liquidity and increased volatility in the fixed income markets. Such issues may be exacerbated during periods of economic uncertainty.

Opinions relating to the validity of municipal bonds and to the exemption of interest thereon from federal income tax and (when available) from treatment as a tax preference item are rendered by bond counsel to the respective issuing authorities at the time of issuance. None of the funds, their investment advisor(s) nor UBS AM reviews the proceedings relating to the issuance of municipal bonds or the basis for such opinions. An issuer's obligations under its municipal bonds are subject to the bankruptcy, insolvency and other laws affecting the rights and remedies of creditors (such as the federal bankruptcy laws) and federal, state and local laws that may be enacted that adversely affect the tax-exempt status of interest on the municipal bonds held by the fund or the exempt-interest dividends received by its shareholders, extend the time for payment of principal or interest, or both, or impose other constraints upon enforcement of such obligations. There is also the possibility that, as a result of litigation or other conditions, the power or ability of issuers to meet their obligations for the payment of principal of a
