UBS U.S. Defensive Equity Fund
Fund summary

Investment objective

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

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" on page 11 of the Fund's prospectus and in "Reduced sales charges, additional purchase, exchange and redemption information and other services" on page 53 of the Fund's statement of additional information ("SAI").

Shareholder fees (fees paid directly from your investment)

	Class A			Class C			Class Y
Maximum front-end sales charge (load) imposed on purchases (as a % of offering price)		5.50	%		None			None
Maximum contingent deferred sales charge (load) (CDSC) (as a % of purchase or sales price, whichever is less)		None1			1.00	%		None
Redemption fee (as a % of amount redeemed within 90 days of purchase, if applicable)		1.00	%		1.00	%		1.00	%

Less management fee waiver/expense reimbursements		1.00			1.08			0.92
Total annual fund operating expenses after management fee waiver/expense reimbursements2,3		2.22			2.97			1.94

¹  Purchases of $1 million or more that were not subject to a front-end sales charge are subject to a 1% CDSC if sold within one year of the purchase date.

²  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 management fee waiver/expense reimbursements" will differ from those presented in the Financial highlights.

³  The Trust, with respect to the Fund, and UBS Global Asset Management (Americas) Inc., the Fund's investment advisor ("UBS Global 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, 2014, otherwise do not exceed 1.50% for Class A shares, 2.25% for Class C shares and 1.25% for Class Y shares. Pursuant to the written agreement, the Advisor is entitled to be reimbursed for any fees it waives and expenses it reimburses for a period of three years following such fee waivers and expense reimbursements, to the extent that such reimbursement of the Advisor by the Fund will not cause the Fund to exceed any applicable expense limit that is in place for the Fund. 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, the UBS Global AM (Americas)'s three year recoupment rights will survive.

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 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:

	1 year		3 years		5 years		10 years
Class A	$	763	$	1,399	$	2,059	$	3,813
Class C (assuming sale of all shares at end of period)		400		1,134		1,985		4,182
Class C (assuming no sale of shares)		300		1,134		1,985		4,182
Class Y		197		799		1,427		3,119

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 85% of the average value of its portfolio.

Principal strategies
Principal investments

Under normal circumstances, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes, if any) in equity and/or equity-related instruments of US companies. Equity-related instruments include securities or other instruments that derive their value from equity securities and may include such instruments as short sales of equity securities, and futures and options on equity securities. The Fund will generally invest in equity securities of large and mid capitalization companies but is permitted to invest up to 15% of its net assets in small capitalization companies. The Fund will maintain both long positions and short positions in equity securities and securities with equity-like characteristics. In addition, up to 20% of the Fund's net assets may be invested in securities of foreign companies in developed countries, including long and short positions in foreign equity securities and securities with equity-like characteristics.

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. The derivatives in which the Fund may invest include futures, options and forward currency agreements. 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. Options may also be used to generate cash flow or enhance returns. In addition, futures on indices may be used for investment (non-hedging) purposes to earn income; to enhance returns; to replace more traditional direct investments; or to obtain exposure to certain markets.

The Fund may also invest in exchange-traded funds ("ETFs") and similarly structured pooled investments in order to provide exposure to the equity markets while maintaining liquidity. The Fund may also engage in short sales of ETFs and similarly structured pooled investments in order to reduce exposure to certain sectors of the equity markets.

Management process

The Advisor's investment style is singularly focused on investment fundamentals. The Advisor believes that investment fundamentals determine and describe future cash flows that define fundamental investment value. The Advisor tries to identify and exploit periodic discrepancies between market prices and fundamental value. These price/value discrepancies are used as the building blocks for portfolio construction.

In constructing the Fund's portfolio, the Advisor primarily uses fundamental analysis and, to a lesser extent, quantitative analysis to identify securities that are underpriced and overpriced relative to their fundamental value. In general, the Advisor buys securities "long" for the Fund's portfolio that it believes are underpriced and will outperform, and sells securities "short" that it believes are overpriced and will underperform. The Fund anticipates that it will normally maintain long positions in equity securities and securities with equity-like characteristics equal to 120% to 140% of the value of its net assets, short positions in equity securities and securities with equity-like characteristics equal to 20% to 40% of the value of its net assets and cash positions equal to 0% to 10% of the value of its net assets. The Fund's ability to fully implement its investment strategy may be affected by (i) regulatory restrictions prohibiting short sales of certain securities that may be imposed from time to time or (ii) the Advisor's written procedures designed to address potential conflicts that exist where the Advisor manages both long-only and long/short accounts and/or funds.

In addition, the Advisor seeks to manage the Fund's equity risk by utilizing an options-based strategy designed to reduce systematic market risk in the Fund's portfolio in extreme down markets. The Advisor regularly purchases and sells exchange-traded and over-the-counter put and call options on securities and indices in order to limit the Fund's downside equity risk in extreme down markets. This strategy may often result in the Fund purchasing an index put option in combination with writing an index put option or a covered call option. The Advisor combines purchased and written options in this manner in order to customize the type and level of extreme market downside protection and to reduce the cost of such downside protection. This options overlay strategy, while expected to be beneficial in providing downside equity protection in extreme down markets, may also limit the Fund's returns in normal or rising markets. In addition, the strategy is not intended to provide downside protection from normal or modest market declines, and is not a total market hedge. The Advisor believes that this defensive options-based overlay strategy provides the Fund with reduced downside equity risk in extreme down markets in an efficient and price-sensitive manner, while enabling the Fund to participate, in part, in rising equity markets. However, under certain market conditions, the Advisor may, in its own discretion, not hedge equity market risk or employ the options-based strategy.

In employing these investment strategies for the Fund, the Advisor seeks to achieve equity-like returns or better with less than equity-like risk or volatility over a full market cycle. The Advisor does not represent or guarantee that the Fund will meet this goal.

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 the 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.

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.

Short sales risk: There are certain unique risks associated with the use of short sales strategies. When selling a security short, the Advisor will sell a security it does not own at the then-current market price and then borrow

the security to deliver to the buyer. The Fund is then obligated to buy the security on a later date so it can return the security to the lender. Short sales therefore involve the risk that the Fund will incur a loss by subsequently buying a security at a higher price than the price at which the Fund previously sold the security short. This would occur if the securities lender required the Fund to deliver the securities the Fund had borrowed at the commencement of the short sale and the Fund was unable to either purchase the security at a favorable price or to borrow the security from another securities lender. If this occurs at a time when other short sellers of the security also want to close out their positions, a "short squeeze" can occur. A short squeeze occurs when demand is greater than supply for the security sold short. Moreover, because the Fund's loss on a short sale arises from increases in the value of the security sold short, such loss, like the price of the security sold short, is theoretically unlimited. By contrast, the Fund's loss on a long position arises from decreases in the value of the security and therefore is limited by the fact that a security's value cannot drop below zero. It is possible that the Fund's securities held long will decline in value at the same time that the value of the securities sold short increases, thereby increasing the potential for loss.

Options-based strategy risk: The Fund regularly purchases and sells exchange-traded and over-the-counter put and call options in order to attempt to limit the Fund's downside risk in extreme down markets. The purchase and sale of exchange-traded and over-the-counter put and call options involves costs, which the Fund will incur on a regular basis, and, therefore, these costs may limit the Fund's returns in normal or rising markets. In addition, there is no guarantee that the Advisor's options-based strategy will provide the expected protection in extreme down markets.

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. When using derivatives for non-hedging purposes, 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 and counterparty risk (which is the risk that a counterparty to a derivative contract is unable or unwilling to meet its financial obligations). In addition, 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.

Leverage risk associated with financial instruments: The use of financial instruments to increase potential returns, including derivatives used for investment

UBS Global Asset Management
5

(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.

Limited 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.

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. Also, foreign securities are sometimes less liquid and more difficult to sell and to value than securities of US issuers.

Unseasoned company risk: The Fund may invest in relatively new or unseasoned companies that are in their early stages of development. Securities of unseasoned companies present greater risks than securities of larger, more established companies. The companies may have greater risks because they (i) may be dependent on a small number of products or services; (ii) may lack substantial capital reserves; and (iii) do not have proven track records.

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 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 market performance. Index reflects no deduction for fees, expenses or taxes. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. On or about January 28, 2013, the Fund's investment strategies, including its 80% policy, changed.

Principal investment strategies

Under normal circumstances, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes, if any) in equity and/or equity-related instruments of US companies. Equity-related instruments include securities or other instruments that derive their value from equity securities and may include such instruments as short sales of equity securities, and futures and options on equity securities. The Fund will generally invest in equity securities of large and mid capitalization companies but is permitted to invest up to 15% of its net assets in small capitalization companies. The Fund will maintain both long positions and short positions in equity securities and securities with equity-like characteristics. For purposes of the Fund's investments, US companies include any company organized outside of the United States but which: (a) is included in the Fund's benchmark index; (b) has its headquarters or principal location of operations in the United States; (c) whose primary listing is on a securities exchange or market in the United States; or (d) derives a majority of its revenues in the United States. In addition, up to 20% of the Fund's net assets may be invested in securities of foreign companies in developed countries, including long and short positions in foreign equity securities and securities with equity-like characteristics.

The Fund will notify shareholders at least 60 days prior to any change in its policy of investing at least 80% of its net assets (plus borrowings for investment purposes, if any) in equity and/or equity-related instruments of US companies.

The Fund may, but is not required to, use 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, or index, and may relate to stocks, bonds, interest rates, currencies or currency exchange rates, and related indexes. Examples of derivatives include options, futures, forward agreements and swap agreements.

The Fund may use derivatives to earn income and enhance returns, to manage or adjust the risk profile of the Fund, to replace more traditional direct investments, or to obtain exposure to certain markets.

The Fund may also invest in ETFs and similarly structured pooled investments in order to provide exposure to the equity markets while maintaining liquidity. The Fund may also engage in short sales of ETFs and similarly structured pooled investments in order to reduce exposure to certain sectors of the equity markets.

Securities selection

The Advisor's investment style is singularly focused on investment fundamentals. The Advisor believes that investment fundamentals determine and describe future cash flows that define fundamental investment value. The Advisor tries to identify and exploit periodic discrepancies between market prices and fundamental value. These price/value discrepancies are used as the building blocks for portfolio construction.

In constructing the Fund's portfolio, the Advisor primarily uses fundamental analysis and, to a lesser extent, quantitative analysis to identify securities that are underpriced and overpriced relative to their fundamental value. In general, the Advisor buys securities "long" for the Fund's portfolio that it believes are underpriced and will outperform, and sells securities "short" that it believes are overpriced and will underperform. The Fund anticipates that it will normally maintain long positions in equity securities and securities with equity-like characteristics equal to 120% to 140% of the value of its net assets, short positions in equity securities and securities with equity-like characteristics equal to 20% to 40% of the value of its net assets and cash positions equal to 0% to 10% of the value of its net assets. The Fund's ability to fully implement its investment strategy may be affected by regulatory restrictions prohibiting short sales of certain securities that may be imposed from time to time.

order to limit the Fund's downside equity risk in extreme down markets. This strategy may often result in the Fund purchasing an index put option in combination with writing an index put option or a covered call option. The Advisor combines purchased and written options in this manner in order to customize the type and level of extreme market downside protection and to reduce the cost of such downside protection. This options overlay strategy, while expected to be beneficial in providing downside equity protection in extreme down markets, may also limit the Fund's returns in normal or rising markets. In addition, the strategy is not intended to provide downside protection from normal or modest market declines, and is not a total market hedge. The Advisor believes that this defensive options-based overlay strategy provides the Fund with reduced downside equity risk in extreme down markets in an efficient and price-sensitive manner, while enabling the Fund to participate, in part, in rising equity markets. However, under certain market conditions, the Advisor may, in its own discretion, not hedge equity market risk or employ the options-based strategy.

In employing these investment strategies for the Fund, the Advisor seeks to achieve equity-like returns or better with less than equity-like risk or volatility over a full market cycle. The Advisor does not represent or guarantee that the Fund will meet this goal.

The Fund may invest in cash or cash equivalent instruments, including shares of an affiliated investment company. When market conditions warrant, the Fund may make substantial temporary defensive investments in cash equivalents, which may affect the Fund's ability to pursue its investment objective. The Advisor actively manages the Fund. As such, increased portfolio turnover may result in higher costs for brokerage commissions, transaction costs and taxable gains. The trading costs and tax effects associated with portfolio turnover may adversely affect the Fund's performance.

More about short sales. When the Fund takes a long position in a security, the Advisor purchases the security outright for the Fund's portfolio. When the Fund takes a short position in a security, the Advisor sells a security that the Fund does not own at the current market price and delivers to the buyer a security that the Fund has borrowed. To complete or close out the short sale transaction, the Fund buys the same security in the market

and returns it to the lender. The Fund makes money when the market price of the security goes down after the short sale. Conversely, if the price of the security goes up after the sale, the Fund will lose money because it will have to pay more to replace the borrowed security than it received. Until the Fund replaces the borrowed security, the Fund is required to maintain during the period of the short sale the short sale proceeds that the broker holds (which may be invested in equity securities) and any additional assets the lending broker requires as collateral. The Fund is also required to designate, on its books or the books of its custodian, liquid assets (less any additional collateral held by the broker) to cover the short sale obligation, marked to market daily. The Fund is also required to repay the lender of the security any dividends or interest that accrue on the security during the period of the loan.

The Fund's ability to fully implement its investment strategy may also be affected by the Advisor's written procedures designed to address potential conflicts that exist where the Advisor manages both long-only and long/short accounts and/or funds. For example, the Advisor restricts short sales in excess of a stated amount of the average daily trading volume of a stock if the Advisor deems it may negatively impact the market and drive down the price of a security that is also held in the Advisor's long only accounts and/or funds. In addition, the Advisor's procedures require short sales to be executed after long-only sell orders in the same stock if the long-only sell orders are in excess of a stated number of shares. This procedure may delay the short sales and therefore the price at which the short sale is executed. Therefore, the price may be lower than had the long-only order not taken precedence, and the potential benefit of the short sale would be reduced.

Principal risks

An investment in the Fund is not guaranteed; you may lose money by investing in the Fund. The other principal risks presented by an investment in the Fund are:

•  Market risk—The risk that the market value of the Fund's investments will fluctuate as the stock and bond markets fluctuate. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole.

The UBS Funds

More information about the fund

•  Management risk—The risk that the investment strategies, techniques and risk analyses employed by the Advisor may not produce the desired results. The Advisor may be incorrect in its assessment of the value of securities or assessment of market trends, which can result in losses to the Fund. Also, in some cases, derivatives or other investments may be unavailable or the Advisor may choose not to use them under market conditions when their use, in hindsight, may be determined to have been beneficial to the Fund. In addition, while it is the intent of the Advisor to take long positions in securities that are undervalued and are expected to subsequently outperform the market and short positions in securities that are overvalued and are expected to underperform the market, in various market conditions, there is no assurance that the Advisor will be successful in its selection process.

•  Short sales risk—There are certain unique risks associated with the use of short sales strategies. When selling a security short, the Advisor will sell a security it does not own at the then-current market price and then borrow the security to deliver to the buyer. The Fund is then obligated to buy the security on a later date so it can return the security to the lender. Short sales therefore involve the risk that the Fund will incur a loss by subsequently buying a security at a higher price than the price at which the Fund previously sold the security short. This would occur if the securities lender required the Fund to deliver the securities the Fund had borrowed at the commencement of the short sale and the Fund was unable to either purchase the security at a favorable price or to borrow the security from another securities lender. If this occurs at a time when other short sellers of the security also want to close out their positions, a "short squeeze" can occur. A short squeeze occurs when demand is greater than supply for the security sold short. Moreover, because the Fund's loss on a short sale arises from increases in the value of the security sold short, such loss, like the price of the security sold short, is theoretically unlimited. By contrast, the Fund's loss on a long position arises from decreases in the value of the security and therefore is limited by the fact that a security's value cannot drop below zero. It is possible that the Fund's securities held long will decline in value at the same time that

the value of the securities sold short increases, thereby increasing the potential for loss.

•  Options-based strategy risk—The Fund regularly purchases and sells exchange-traded and over-the-counter put and call options in order to attempt to limit the Fund's downside risk in extreme down markets. The purchase and sale of exchange-traded and over-the-counter put and call options involves costs, which the Fund will incur on a regular basis, and, therefore, these costs may limit the Fund's returns in normal or rising markets. In addition, there is no guarantee that the Advisor's options-based strategy will provide the expected protection in extreme down markets.

•  Derivatives risk—Derivatives involve risks different from, and possibly greater than, the risks associated with investing directly in securities and other instruments. Derivatives require investment techniques and risk analyses different from those of other investments. If the Advisor incorrectly forecasts the value of securities, currencies, interest rates, or other economic factors in using derivatives, the Fund might have been in a better position if the Fund had not entered into the derivatives. While some strategies involving derivatives can protect against the risk of loss, the use of derivatives can also reduce the opportunity for gain or even result in losses by offsetting favorable price movements in other Fund investments. Derivatives also involve the risk of mispricing or improper valuation, the risk that changes in the value of a derivative may not correlate perfectly with the underlying asset, rate, index, or overall securities markets, and counterparty and credit risk (the risk that the other party to a swap agreement or other derivative will not fulfill its contractual obligations, whether because of bankruptcy or other default). Gains or losses involving some options, futures, and other derivatives may be substantial (for example, for some derivatives, it is possible for the Fund to lose more than the amount the Fund invested in the derivatives). Some derivatives tend to be more volatile than other investments, resulting in larger gains or losses in response to market changes. Derivatives are subject to a number of other risks, including liquidity risk (the possible lack of a secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close out the derivatives) and interest

rate risk (some derivatives are more sensitive to interest rate changes and market price fluctuations). Finally, the Fund's use of derivatives may cause the Fund to realize higher amounts of short-term capital gains (generally taxed at ordinary income tax rates) than if the Fund had not used such instruments.

•  Writing call options—The Fund may write covered call options (in which the Fund owns the corresponding amount of the underlying instrument, such as specific securities) or uncovered call options (in which the Fund maintains assets for the term of the option having a value equal to the fluctuating market value of the optioned basket of securities, such as an index, marked-to-market daily). Writing a call generates cash flow in the form of the premium paid by the option buyer. If the price of the underlying security or basket of securities remains stable or increases, then the writer will be able to keep this cash flow as a profit, even though the profit may have been higher if no call were written. If the price of the underlying security or basket of securities declines, then the net position will likely lose money.

•  Writing put options—The Fund may write put options (in which the Fund maintains assets in an amount not less than fluctuating market value of the exercise price of the option, marked-to-market daily at all times during the option period). In writing a put option, the Fund bears the risk that if the underlying instrument's price falls, the Fund could suffer a loss (less any premium received by the Fund for the option) because it would be required to pay a higher price for the underlying instrument than what the current market price of the instrument would be at the time of exercise of the option.

•  Leverage risk associated with financial instruments—Certain derivatives that the Fund may use may create leverage. Derivatives that involve leverage can result in losses to the Fund that exceed the amount originally invested in the derivatives.

•  Limited capitalization risk—The risk that investments in small and mid capitalization size companies may be more volatile than investments in larger companies, as small and mid capitalization companies

generally experience higher growth and failure rates than larger capitalization companies. The trading volume of these securities is normally lower than that of larger companies. Such securities may be less liquid than others and this could make it difficult to sell a security at a time or price desired. Changes in the demand for these securities generally have a disproportionate effect on their market price, tending to make prices rise more in response to buying demand and fall more in response to selling pressure than prices for larger companies.

•  Foreign investing risk—The risk that prices of the Fund's investments in foreign securities may go down because of unfavorable foreign government actions, political instability or the absence of accurate information about foreign issuers. In addition, a decline in the value of foreign currencies relative to the US dollar will reduce the value of securities denominated in those currencies. Also, foreign securities are sometimes less liquid and harder to buy, sell and to value than securities of US issuers.

•  Unseasoned company risk—The Fund may invest in relatively new or unseasoned companies that are in their early stages of development. Securities of unseasoned companies present greater risks than securities of larger, more established companies. The companies may have greater risks because they (i) may be dependent on a small number of products or services; (ii) may lack substantial capital reserves; and (iii) do not have proven track records.

Other information

Commodity pool operator exemption—The Trust, with respect to the Fund, has claimed an exclusion from the definition of the term "commodity pool operator" ("CPO") under the Commodity Exchange Act ("CEA"), and, therefore, is not subject to registration or regulation as a CPO under the CEA. The Commodity Futures Trading Commission has adopted recent amendments to rules under the CEA that significantly affect the exclusion available to funds. The Fund may consider steps, such as substantial investment strategy changes, in order for the Trust, with respect to the Fund, to continue to qualify for the CPO exclusion.

Managing your fund account

Flexible pricing

The Fund offers three classes of shares—Class A, Class C and Class Y. Each class has different sales charges and ongoing expenses. You can choose the class that is best for you, based on how much you plan to invest and how long you plan to hold your shares of the Fund. Class Y shares are only available to certain types of investors.

The Fund has adopted separate plans pertaining to the Class A and Class C shares of the Fund under Rule 12b-1 that allow the Fund to pay service and (for Class C shares) distribution fees for the sale of the Fund's shares and services provided to shareholders. Because the 12b-1 fees for Class C shares are paid out of the Fund's assets on an ongoing basis, over time they will increase the cost of your investment and may cost you more than if you paid other types of sales charges, such as the front-end sales charge for Class A shares.

You may qualify for a waiver of certain sales charges on Class A and Class C shares. See "Sales charge waivers for Class A and Class C shares" later in this prospectus. You may also qualify for a reduced sales charge on Class A shares. See "Sales charge reductions for Class A shares" later in this prospectus.

Class A shares

Class A shares have a front-end sales charge that is included in the offering price of the Class A shares. This sales charge is paid at the time of purchase and is not invested in the Fund. The Fund's Class A shares pay an annual service fee of 0.25% of average net assets. Class A shares pay no distribution fees. The ongoing expenses for Class A shares are lower than for Class C shares.

The Class A sales charges for the Fund are described in the following table:

Class A sales charges

	Sales charge as a percentage of:						Reallowance to selected dealers as
Amount of investment	Offering price			Net amount invested			percentage of offering price
Less than $50,000		5.50	%		5.82	%		5.00	%
$50,000 to $99,999		4.50			4.71			4.00
$100,000 to $249,999		3.50			3.63			3.00
$250,000 to $499,999		2.50			2.56			2.00
$500,000 to $999,999		2.00			2.04			1.75
$1,000,000 and over1		None			None			May pay up to 1.002

¹  A contingent deferred sales charge of 1% of the shares' offering price or the net asset value at the time of sale by the shareholder, whichever is less, is charged on sales of shares made within one year of the purchase date. Class A shares representing reinvestment of dividends are not subject to this 1% charge. Withdrawals in the first year after purchase of up to 12% of the value of the fund account under the Fund's Automatic Cash Withdrawal Plan are not subject to this charge.

²  For sales of $1 million or more, UBS Global Asset Management (US) Inc. pays to the dealer an amount based upon the following schedule: 1.00% on the first $3 million, 0.75% on the next $2 million, and 0.50% on the next $5 million.

UBS Global Asset Management
12

The UBS Funds

If you intend to purchase more than $5 million of Class A shares, you should instead purchase Class Y shares, which have lower on-going expenses.

Class C shares

Class C shares pay an annual 12b-1 distribution fee of 0.75% of average net assets. Class C shares of the Fund also pay an annual 12b-1 service fee of 0.25% of average net assets. Class C shares do not convert to another class of shares. This means that you will pay the 12b-1 fees for as long as you own your shares.

Class C shares also have a contingent deferred sales charge of 1.00%, applicable if you sell your shares within one year of the date you purchased them. We calculate the deferred sales charge on sales of Class C shares by multiplying 1.00% by the lesser of the net asset value of the Class C shares at the time of purchase or the net asset value at the time of sale.

Sales charge waivers for Class A and Class C shares

Class A front-end sales charge waivers—Front-end sales charges will be waived if you buy Class A shares with proceeds from the following sources:

The UBS Funds

Class A and Class C shares contingent deferred sales charge waivers—The contingent deferred sales charge will be waived for:

•  Redemptions of Class A shares by former holders of Class N shares;

•  Exchanges between funds for which UBS Global AM (US) or one of its affiliates serves as principal underwriter, if purchasing the same class of shares;

—the minimum account value at the time the Automatic Cash Withdrawal Plan was initiated was no less than $5,000;

•  Redemptions of shares purchased through certain retirement plans;

•  Broker-dealers or other financial institutions that have entered into an agreement with UBS Global AM (US), on behalf of clients participating in certain self-directed investment brokerage accounts, in which clients may or may not pay a transaction fee to the broker-dealer or financial institution.

Sales charge reductions for Class A shares right of accumulation. A purchaser of Class A shares may

qualify for a reduction of the front-end sales charge on purchases of Class A shares by combining a current purchase with certain other Class A, Class C, Class P and/or Class Y shares of Family Funds ("Family Funds" include other UBS Funds, PACE Select funds and other funds for which UBS Global AM (US) serves as principal underwriter)¹ already owned. To determine if you qualify for a reduction of the front-end sales charge, the amount of your current purchase is added to the current net asset value of your other Class A, Class C, Class P and/or Class Y shares, as well as those Class A, Class C, Class P and/or Class Y shares of your spouse and children under the age of 21 and who reside in the same household. If you are the sole owner of a company, you may also add any company accounts, including retirement plan accounts invested in Class A, Class C, Class P and/or Class Y shares of the Family Funds. Companies with one or more retirement plans may add together the total plan assets invested in Class A, Class C, Class P and/or Class Y shares of the Family Funds to determine the front-end sales charge that applies. To qualify for the discount on a purchase through a financial institution, when each purchase is made, the investor or institution must provide UBS Global AM (US) with sufficient information to verify that the purchase qualifies for the privilege or discount. The right of accumulation may be amended or terminated by UBS Global AM (US) at any time as to purchases occurring thereafter.

Shares purchased through a broker/dealer may be subject to different procedures concerning Rights of Accumulation. Please contact your investment professional for more information.

Letter of Intent

Investors may also obtain reduced sales charges for Class A shares for investments of a particular amount by means of a written Letter of Intent, which expresses the investor's intention to invest that amount within a period of 13 months in shares of one or more Family Funds.¹ Each purchase of Class A shares under a Letter of Intent will be made at the public offering price applicable at the time of such purchase to a single transaction of the total dollar amount indicated in the Letter of Intent. A Letter of Intent may include purchases of Class A, Class C and/or Class Y shares made not more

The UBS Funds

than three months prior to the date that the investor signs a Letter of Intent and during the 13-month period in which the Letter of Intent is in effect; however, the 13-month period during which the Letter of Intent is in effect will begin on the date on which the Letter of Intent is signed.

Investors do not receive credit for shares purchased by the reinvestment of distributions. Investors qualifying for a right of accumulation discount (described above) may purchase shares under a single Letter of Intent.

The Letter of Intent is not a binding obligation upon the investor to purchase the full amount indicated. The minimum initial investment under a Letter of Intent is 5% of such amount, which must be invested immediately. Class A shares purchased with the first 5% of such amount may be held in escrow to secure payment of the higher sales charge applicable to the shares actually purchased if the full amount indicated is not purchased. When the full amount indicated has been purchased, the escrow will be released. If an investor desires to redeem escrowed shares before the full amount has been purchased, the shares will be released only if the investor pays the sales charge that, without regard to the Letter of Intent, would apply to the total investment made to date.

Letter of Intent forms may be obtained from UBS Global AM (US) or from investment professionals. Investors should read the Letter of Intent carefully.

Shares purchased through a broker/dealer may be subject to different procedures concerning Letters of Intent. Please contact your investment professional for more information.

Note on sales charge reductions and waivers for Class A and Class C shares

Additional information concerning sales charge reductions and waivers is available in the Fund's SAI. If you think you qualify for any of the sales charge waivers or reductions described previously, you may need to notify and/or provide documentation to UBS Global AM (US). You will also need to notify UBS Global AM (US) of the existence of other accounts in which there are holdings eligible to be aggregated to meet certain sales load breakpoints.

Class Y shares

Shareholders pay no front-end or deferred sales charges on Class Y shares. UBS Global AM (US), the principal underwriter of the Fund, may make payments out of its own resources to certain affiliated dealers (e.g., UBS Financial Services Inc.) and, from time to time, unaffiliated dealers in UBS Global AM (US)'s sole discretion. Only specific types of investors can purchase Class Y shares.

The following are eligible to purchase Class Y shares:

•  Shareholders of the Class I shares of any UBS Fund who held such shares as of the date the shares were redesignated Class Y shares;

•  Retirement plans with 5,000 or more eligible employees or $100 million or more in plan assets;

•  Retirement plan platforms/programs that include Fund shares if the platform/program covers plan assets of at least $100 million;

UBS Global Asset Management

The UBS Funds

•  Trust companies and bank trust departments purchasing shares on behalf of their clients in a fiduciary capacity;

•  Banks, registered investment advisors and other financial institutions purchasing Fund shares for their clients as part of a discretionary asset allocation model portfolio;

•  Shareholders who owned Class Y shares of the Fund through the PACE Multi-Advisor Program as of November 15, 2001, will be eligible to continue to purchase Class Y shares of the Fund through the program;

•  College savings plans organized under Section 529 of the IRC, if shareholder servicing fees are paid exclusively outside of the participating funds;

•  Other investors as approved by the Fund's Board of Trustees;

•  Shareholders who invest a minimum initial amount of $5 million in the Fund. An institutional investor may aggregate its holdings with holdings of certain related institutional investors to meet the foregoing minimums;

•  Foundations, Endowments and Religious and other charitable organizations described in Section 501(c)(3) of the IRC that invest a minimum initial amount of $2,500,000;

•  Employees of UBS Global AM (Americas) and UBS Global AM (US), as long as the employee establishes an account in his or her name directly at the Fund's transfer agent and purchases a minimum initial amount of $50,000; and

•  Members of the Board of Directors/Trustees (and former Board members who retire from such Boards after December 1, 2005) of any investment company for which UBS Global AM (US) or any of its affiliates serves as principal underwriter, subject to a minimum initial purchase amount of $50,000 in an account established by the member in his or her name directly at the Fund's transfer agent.

Class Y shares do not pay ongoing 12b-1 distribution or service fees. The ongoing expenses for Class Y shares are the lowest of all the classes.

Buying shares

You can buy Fund shares through your investment professional at a broker-dealer or other financial institution with which UBS Global AM (US) has a dealer agreement.

If you wish to invest in other Family Funds, you can do so by:

•  Contacting your investment professional (if you have an account at a financial institution that has entered into a dealer agreement with UBS Global AM (US));

•  Buying shares through the transfer agent as described later in this prospectus; or

•  Opening an account by exchanging shares from another Family Fund.

Selected securities dealers or other financial institutions, including UBS Financial Services Inc., may charge a processing fee to confirm a purchase. UBS Financial Services Inc. currently charges a fee of $5.25.

The Fund and UBS Global AM (US) reserve the right to reject a purchase order or suspend the offering of shares.

Through financial institutions/professionals

As mentioned above, the Fund has entered into one or more sales agreements with brokers, dealers or other financial intermediaries ("Service Providers"), as well as with financial institutions (banks and bank trust departments) (each an "Authorized Dealer"). The Authorized Dealer, or intermediaries designated by the Authorized Dealer (a "Sub-designee"), may in some cases be authorized to accept purchase and redemption orders that are in "good form" on behalf of the Fund. The Fund will be deemed to have received a purchase or redemption order when the Authorized Dealer or Sub-designee receives the order in good form. Such orders will be priced at the Fund's net asset value next computed after such order is received in good form by the Authorized Dealer or Sub-designee. These Authorized Dealers may charge the investor a transaction fee or other fee for their services at the time of purchase. These fees

UBS Global Asset Management
16

The UBS Funds

would not be otherwise charged if you purchased shares directly from the Fund. It is the responsibility of such Authorized Dealers or Sub-designees to promptly forward purchase orders with payments to the Fund.

Additional compensation to affiliated dealer

UBS Global AM (US) pays its affiliate, UBS Financial Services Inc., the following additional compensation in connection with the sale of Fund shares:

•  0.05% of the value (at the time of sale) of all shares of the Fund sold through UBS Financial Services Inc.; and

•  a monthly retention fee at the annual rate of 0.10% of the value of shares of the Fund's portfolio that are held in a UBS Financial Services Inc. account at month-end.

The foregoing payments are made by UBS Global AM (US) out of its own resources. These payments are often referred to as "revenue sharing."

Additional compensation to financial institution(s)

UBS Global AM (US) or the Advisor may pay compensation, out of the Advisor's profits and not as an additional charge to the Fund, to certain financial institutions (which may include banks, securities dealers and other industry professionals) for the sale and/or distribution of Fund shares or the retention and/or servicing of Fund investors and Fund shares. These payments are often referred to as "revenue sharing." Revenue sharing payments are paid in addition to any distribution or servicing fees payable under a 12b-1 or service plan of the Fund, any record keeping or sub-transfer agency fees payable by the Fund, or other fees described in the fee tables or elsewhere in the prospectus or SAI. Revenue sharing payments are paid from the Advisor's own resources and not as an additional charge to the Fund.

The level of revenue sharing payments made to financial institutions may be a fixed fee or based upon one or more of the following factors: gross sales, current assets and/or number of accounts of the Fund attributable to the financial institution, or other factors as agreed to by the Advisor and the financial institution or any combination thereof. The amount of the revenue share may be different for different financial

institutions. For specific information about revenue sharing arrangements for a particular financial institution please see the SAI.

In some circumstances, revenue sharing payments may create an incentive for a financial institution, its employees or associated persons to recommend or sell shares of the Fund to you. You should consult with your financial advisor and review carefully any disclosure by the financial institution as to compensation received.

Minimum investments:

Class A and Class C shares:

To open an account	$	1,000
To add to an account	$	100

The Fund may waive or reduce these amounts for:

•  Employees of UBS Global AM (US) or its affiliates; or

•  Participants in certain pension plans, retirement accounts, unaffiliated investment programs or the Fund's automatic investment plan.

Market timers. The interests of the Fund's long-term shareholders and their ability to manage their investments may be adversely affected when their shares are repeatedly bought and sold in response to short-term market fluctuations—also known as "market timing." Market timing may cause the Fund to have difficulty implementing long-term investment strategies, because it cannot predict how much cash it will have to invest. Market timing also may force the Fund to sell portfolio securities at disadvantageous times to raise the cash needed to buy a market timer's Fund shares. Market timing also may materially increase the Fund's transaction costs, administrative costs or taxes. These factors may hurt the Fund's performance and its shareholders.

In addition, the nature of the Fund's portfolio holdings may allow a shareholder to engage in a short-term trading strategy to take advantage of possible delays between the change in the Fund's portfolio holdings and the reflection of that change in the Fund's net asset value (often called "arbitrage market timing"). Such a delay may occur if the Fund has significant investments in non-US securities, where due to time zone differences, the value of those securities is established

UBS Global Asset Management
17

The UBS Funds

some time before the Fund calculates its net asset value. In such circumstances, the available market prices for such non-US securities may not accurately reflect the latest indications of value at the time the Fund calculates its net asset value. The Fund also may be subject to arbitrage market timing because the Fund may have significant holdings in smaller cap securities, which may have market prices that do not accurately reflect the latest indications of value of these securities at the time that the Fund calculates its net asset value due to, among other reasons, infrequent trading or illiquidity. There is a possibility that arbitrage market timing may dilute the value of Fund shares if redeeming shareholders receive proceeds (and buying shareholders receive shares) based upon a net asset value that does not reflect appropriate fair value prices. One of the objectives of the Fund's fair value pricing procedures is to minimize the possibilities of this type of arbitrage market timing.

The Board of Trustees of the Trust has adopted the following policies as a means to discourage, detect and prevent market timing. The Fund will reject purchase orders and exchanges into the Fund by any person, group or account that UBS Global AM (Americas), as the Fund's Advisor and Administrator, determines to be a market timer. UBS Global AM (Americas) maintains market timing prevention procedures under which it reviews daily reports from the Fund's transfer agent of all accounts that engaged in transactions in Fund shares that exceed a specified monetary threshold and effected such transactions within a certain period of time to evaluate whether any such account had engaged in market timing activity. In evaluating the account transactions, UBS Global AM (Americas) will consider the potential harm of the trading or exchange activity to the Fund or its shareholders. If UBS Global AM (Americas) determines, in its sole discretion, that a shareholder has engaged in market timing, the shareholder will be permanently barred from making future purchases or exchanges into the Fund. Additionally, in making a determination as to whether a shareholder has engaged in market timing, the shareholder's account may be temporarily barred from making additional investments into the Fund pending a definitive determination. In addition, if a Financial Advisor is identified as the Financial Advisor of two or more accounts that have engaged in market timing, UBS Global AM (Americas)

may prohibit the Financial Advisor from making additional purchases of the Fund on behalf of its clients.

Shares of the Fund may be held through omnibus account arrangements, whereby a broker-dealer, investment advisor, retirement plan sponsor or other financial intermediary (each a "Financial Intermediary") maintains an omnibus account with the Fund for trading on behalf of its customers or participants. Omnibus accounts are accounts that aggregate the transactions of underlying shareholders, thus making it difficult to identify individual underlying account holder activity. UBS Global AM (Americas) reviews purchase and redemption activity in omnibus accounts on a daily basis to seek to identify an unusual pattern of trading activity within a short period of time. If UBS Global AM (Americas) detects an unusual pattern of trading activity, UBS Global AM (Americas) will notify the Financial Intermediary of the omnibus account and will request that the Financial Intermediary provide underlying account detail. If UBS Global AM (Americas) identifies market timing activity, it will instruct the Financial Intermediary to block the customer or participant from further purchases of Fund shares. In the event that the Financial Intermediary cannot identify and block the customer or participant, UBS Global AM (Americas) will require the Financial Intermediary to block the particular plan from further purchases of Fund shares. UBS Global AM (Americas) also will periodically request underlying account detail for omnibus accounts for review and analysis.

While the Fund will seek to take actions (directly and with the assistance of Financial Intermediaries) that will detect market timing, the Fund's efforts may not be completely successful in minimizing or eliminating such trading activity.

When it is determined that a Financial Intermediary's frequent trading policies and procedures sufficiently protect Fund shareholders, the Fund and UBS Global AM (Americas) may rely on the Financial Intermediary's frequent trading policies and procedures with respect to transactions by shareholders investing through the Financial Intermediary rather than applying the Fund's market timing prevention procedures. The determination to rely on a Financial Intermediary's frequent trading policies and procedures will be made after a review

UBS Global Asset Management
18

The UBS Funds

of the policies and procedures by the Legal and Compliance Departments of UBS Global AM (Americas). The Chief Compliance Officer of UBS Global AM (Americas) will determine whether the policies and procedures sufficiently protect Fund shareholders. The types of Financial Intermediaries that may have frequent trading policies and procedures on which the Fund and UBS Global AM (Americas) may rely may include broker-dealers, advisors, clearing firms, bank trust departments, retirement plan administrators, other record keepers and certain wrap fee program/platforms. In such cases, a Financial Intermediary through which a shareholder may own Fund shares may impose frequent trading restrictions that differ from those of the Fund. If you have purchased shares through a Financial Intermediary as described above, you should contact your Financial Intermediary to determine the frequent trading restrictions that apply to your account.

Certain types of transactions will also be exempt from the market timing prevention procedures. These exempt transactions are purchases and redemptions through the Automatic Cash Withdrawal Plan, purchases through an automatic investment plan, redemptions by wrap fee accounts that have an automatic rebalancing feature and that have been identified to the Fund's principal underwriter and transfer agent, certain non-participant directed transactions in retirement plans, and purchases and redemptions by UBS funds of funds.

Selling shares

You can sell your Fund shares at any time. If you own more than one class of shares, you should specify which class you want to sell. If you do not, the Fund will assume that you want to sell shares in the following order: Class A, then Class C and last, Class Y.

If you want to sell shares that you purchased recently, the Fund may delay payment until it verifies that it has received good payment. If you hold your shares through a financial institution, you can sell shares by contacting your investment professional, or an Authorized Dealer or Sub-designee, for more information. Important note: Each institution or professional may have its own procedures and requirements for selling shares

and may charge fees. If you purchased shares through the Fund's transfer agent, you may sell them as explained later in this prospectus.

If you sell Class A shares and then repurchase Class A shares of the Fund within 365 days of the sale, you can reinstate your account without paying a sales charge.

Securities dealers or other financial institutions, including UBS Financial Services Inc., may charge a fee to process a redemption of shares. UBS Financial Services Inc. currently charges a fee of $5.25.

The Fund reserves the right to pay redemptions "in kind" (i.e., payment in securities rather than cash) if the investment you are redeeming is large enough to affect the Fund's operations (for example, if it represents more than $250,000 or 1% of the Fund's assets). In these cases, you might incur brokerage costs converting the securities to cash.

It costs the Fund money to maintain shareholder accounts. Therefore, the Fund reserves the right to repurchase all shares in any account that has a net asset value of less than $500. Any applicable deferred sales charge may be assessed on such redemptions. If the Fund elects to do this with your account, it will notify you that you can increase the amount invested to $500 or more within 60 days. The Fund will not repurchase shares in accounts that fall below $500 solely because of a decrease in the Fund's net asset value.

To help the government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify and record information that identifies each person who opens an account. If you do not provide the information requested, the Fund may not be able to maintain your account. If the Fund is unable to verify your identity or that of another person(s) authorized to act on your behalf, the Fund and UBS Global AM (Americas) reserve the right to close your account and/or take such other action they deem reasonable or required by law. Fund shares will be redeemed and valued in accordance with the net asset value next calculated after the determination has been made to close the account.

Redemption fee

If you sell or exchange any class of shares of the Fund less than 90 days after you purchased them, a redemption fee of 1.00% of the amount sold or exchanged will be deducted at the time of the transaction, except as noted below. This amount will be paid to the applicable Fund, not to the Advisor or UBS Global AM (US). The redemption fee is designed to offset the costs associated with fluctuations in Fund asset levels and cash flow caused by short-term shareholder trading. Shares held the longest will be redeemed first for purposes of calculating the redemption fee. The redemption fee will not apply to shares of the Fund that:

•  are held in certain omnibus accounts of certain Financial Intermediaries, such as broker-dealers or qualified retirement plans including 401 (k), 403(b) or 457 plans or plans administered as college savings programs under Section 529 of the IRC, if those institutions have not implemented the system changes necessary to be capable of processing the redemption fee. However, account holders whose investments in the Fund are held in omnibus accounts through certain other Financial Intermediaries may be subject to the redemption fee on terms that are generally in accordance with the redemption fee terms as described in this prospectus but that may differ in certain details. For certain retirement plans treated as omnibus accounts by the Fund's transfer agent or principal underwriter, the redemption fee will be waived on non-participant initiated exchanges or redemptions;

•  are sold or exchanged under automatic withdrawal plans;

•  are held by investors in certain asset allocation programs that offer automatic rebalancing or wrap-fee or similar fee-based programs and that have been identified to the Fund's principal underwriter and transfer agent, except to the extent that transactions in those programs are shareholder initiated;

•  are sold due to death or disability of the shareholder; or

•  UBS Global AM (Americas), in its sole discretion, deems reasonable, in light of the circumstances.

Exchanging shares

You may exchange Class A or Class C shares of the Fund for shares of the same class of most other Family Funds. You may not exchange Class Y shares.

You will not pay either a front-end sales charge or a deferred sales charge when you exchange shares, but shareholders may be subject to a redemption fee as noted above. Also, you may have to pay a deferred sales charge if you later sell the shares you acquired in the exchange. The Fund will use the date of your original share purchase to determine whether you must pay a deferred sales charge when you sell the shares of the fund acquired in the exchange.

Other Family Funds may have different minimum investment amounts. You may not be able to exchange your shares if the value of shares you exchange is not as large as the minimum investment amount in that other fund.

You may exchange shares of one fund for shares of another Family Fund only after the first purchase has settled and the first fund has received your payment.

If you hold your Fund shares through a financial institution, you may exchange your shares by placing an order with that institution. If you hold Fund shares through the Fund's transfer agent, you may exchange your shares as explained below.

The Fund may modify or terminate the exchange privilege at any time.

Transfer of account limitations

If you hold your shares with UBS Financial Services, Inc. or another securities firm, please note that if you change securities firms, you may not be able to transfer your Fund shares to an account at the new securities firm.

Pricing and valuation

The price at which you may buy, sell or exchange Fund shares is based on the net asset value per share. The Fund calculates 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

UBS Global Asset Management
21

The UBS Funds

open, and the Fund does not price its shares, on most national holidays and on Good Friday. 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 will be calculated as of the time trading was halted.

Your price for buying, selling or exchanging shares of the Fund will be based on the net asset value (adjusted for any applicable sales charges and redemption fees) that is next calculated after the Fund (or an Authorized Dealer or Sub-designee) receives your order in good form. If you place your order through a financial institution, your investment professional is responsible for making sure that your order is promptly sent to the Fund.

The Fund calculates its net asset value based on the current market value, where available, for its portfolio securities. The Fund normally obtains market values for its securities and other instruments 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 securities or instruments. 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 securities or instruments. If a market value is not readily available from an independent pricing source for a particular security or instrument, that security or instrument is valued at fair value as determined in good faith by or under the direction of the Trust's Board of Trustees.

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 (or a committee designated by it) 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, investments in non-registered investment companies are also valued at the daily net asset value. All investments quoted in foreign currencies will be valued daily in US dollars on the basis of the foreign currency exchange rates prevail-

ing at the time such valuation is determined by the Fund's custodian. Foreign currency exchange rates are generally determined as of the close of the NYSE.

Securities and instruments 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. Securities and instruments 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.

The Trust's Board of Trustees has delegated to the UBS Global AM (Americas)' Global Valuation Committee the responsibility for making fair value determinations with respect to the Fund's portfolio holdings. The types of securities and other instruments for which such fair value pricing may be necessary include, but are not limited to: foreign securities and instruments under some circumstances, as discussed below; securities of an issuer that has entered into a restructuring; securities or instruments 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 securities or instruments that are restricted as to transfer or resale. The need to fair value the Fund's portfolio securities and other instruments may also result from low trading volume in foreign markets or thinly traded domestic securities or instruments, and when a security 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 a security's or instrument'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 securities or instruments; and the evaluation of forces which influence the market in which the securities or instruments are purchased and sold.

The Fund expects to price most of its portfolio holdings based on current market value, as discussed previously. Securities and assets for which market quotations are not readily available may be valued based upon

UBS Global Asset Management
22

The UBS Funds

appraisals received from a pricing service using a computerized evaluation system or formula method that takes into consideration market indices, matrices, yield curves and other specific adjustments. This may result in the securities or other instruments being valued at a price different from the price that would have been determined had the evaluation or formula method not been used. Securities and other instruments also may be valued based on appraisals derived from information concerning the security or instrument or similar securities or instruments received from recognized dealers in those holdings. If the Fund concludes that a market quotation is not readily available for a portfolio security or instrument for any number of reasons, including the occurrence of a "significant event" (e.g., natural disaster or governmental action), after the close of trading in its principal domestic or foreign market but before the close of regular trading on the NYSE, the Fund will use fair value methods to reflect those events. This policy is intended to assure that the Fund's net asset value fairly reflects the value of its portfolio holdings as of the time of pricing. The Fund may use a systematic fair valuation model provided by an independent third party to value securities or instruments 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 a security or instrument is valued at a "fair value," that value is likely to be different from the last quoted market price for the security or instrument. In cases where securities or instruments are traded on more than one exchange, the securities or instruments are valued on the exchange designated as the primary market by UBS Global AM (Americas), the investment advisor of the Fund.

Valuing securities and other instruments at fair value involves greater reliance on judgment than valuing securities and other instruments that have readily available market quotations. Fair value determinations can also involve reliance on quantitative models employed by a fair value pricing service. There can be no assurance that the Fund could obtain the fair value assigned to a security or instrument if it were to sell the security or instrument at approximately the time at which the Fund

determines its net asset value per share. As a result, the Fund's sale or redemption of its shares at net asset value, at a time when a holding or holdings are valued at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

The Fund may invest in securities or instruments that trade primarily in foreign markets that trade on weekends or other days on which the Fund does not calculate its net asset value. As a result, the Fund's net asset value may change on days when you will not be able to buy and sell your Fund shares. Certain securities or instruments in which the Fund invests are 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 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 securities or instruments, the Fund may adjust the previous closing prices to reflect what the Board believes to be the fair value of these securities or instruments as of 4:00 p.m., Eastern time.

Futures contracts are generally valued at the settlement price established each day on the exchange on which they are traded. Forward foreign currency contracts 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 and the change in value, if any, is recorded as an unrealized gain or loss on the Statement of assets and liabilities. 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 (or a committee designated by it).

The Fund's portfolio holdings may also consist of shares of other investment companies in which the Fund invests. The value of each such investment company will be its net asset value at the time the Fund's shares are priced. Each investment company calculates its net asset value based on the current market value for its portfolio holdings. Each investment company values securities and other instruments in a manner as described in that investment company's prospectus.

investment advisory fees as set forth in the Fund's expenses and fee table in the line item "Management fees."

The Advisor has contractually agreed to waive its fees and/or reimburse certain expenses so that the ordinary operating expenses of the Fund (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) do not exceed the amounts listed in the footnote to the Fund's Expense Table.

Disclosure of portfolio holdings

The Fund will generally post on its Web Site at http://www.ubs.com/us/en/asset_management/
individual_investors/mutual_fund.html, the ten largest stock portfolio holdings of the Fund, and the percentage that each of these holdings represents of the Fund's total assets, as of the most recent calendar-quarter end, 25 calendar days after the end of the calendar quarter. The Fund will generally post on the Web Site: (1) its ten largest long and five largest short positions; (2) the three long and the three short positions that were the top contributors to its performance; and (3) the three long and the three short positions that were the most significant detractors from its performance, all as of the most recent calendar quarter end, 30 days after the end of each calendar quarter. The Fund will file its complete schedule of portfolio holdings with the SEC for the first and third quarters of each fiscal year on Form N-Q. The

Fund's Forms N-Q are available on the SEC's Web Site at www.sec.gov. The Fund's Forms N-Q may be reviewed and copied at the SEC's Public Reference Room in Washington, D.C. Information on the operation of the SEC's Public Reference Room may be obtained by calling 202-551 8090. Additionally, you may obtain copies of Forms N-Q from the Fund upon request by calling 1-800-647 1568. The Fund's complete schedule of portfolio holdings for the second and fourth quarters of each fiscal year is filed with the SEC on Form N-CSR and appears in the semiannual and annual reports, respectively, sent to shareholders. The semiannual and annual reports for the Fund will be posted on the Fund's Web Site at http://www.ubs.com/us/en/asset_management/
individual_investors/mutual_fund.html. Please consult the Fund's SAI for a description of the policies and procedures that govern disclosure of the Fund's portfolio holdings.

Dividends and taxes

Dividends and distributions

The Fund intends to qualify each year as a regulated investment company under the IRC. As a regulated investment company, the Fund generally pays no federal

UBS Global Asset Management
25

The UBS Funds

income tax on the income and gains it distributes to you. The Fund expects to declare and distribute all of its net investment income, if any, to shareholders as dividends annually. The Fund will distribute net realized capital gains, if any, at least annually, usually in December. The Fund may distribute such income dividends and capital gains more frequently, if necessary, in order to reduce or eliminate federal excise or income taxes on the Fund. The amount of any distribution will vary, and there is no guarantee the Fund will pay either an income dividend or a capital gains distribution.

Classes with higher expenses are expected to have lower income dividends.

You will receive income dividends and capital gain distributions in additional shares of the same class of the Fund unless you notify your investment professional or the Fund in writing that you elect to receive them in cash. Clients who own Fund shares through certain wrap fee programs may not have the option of electing to receive dividends in cash. Distribution options may be changed at any time by requesting a change in writing. Dividends and distributions are reinvested on the reinvestment date at the net asset value determined at the close of business on that date.

Annual statements—Each year, the Fund will send you annual statements (Forms 1099) of your account activity to assist you in completing your federal, state and local tax returns. Distributions declared in December to shareholders of record in such month, but paid in January, are taxable as if they were paid in December. Prior to issuing your statements, the Funds make every effort to reduce the number of corrected forms mailed to shareholders. However, if a Fund finds it necessary to reclassify its distributions or adjust the cost basis of any covered shares sold or exchanged after you receive your tax statement, the Fund will send you a corrected Form 1099.

Avoid "buying a dividend"—At the time you purchase your Fund shares, the Fund's net asset value may reflect undistributed income, undistributed capital gains, or net unrealized appreciation in value of portfolio securities held by the Fund. For taxable investors, a subsequent distribution to you of such amounts, although constituting a return of your investment, would be taxable. Buying shares in the Fund just before it declares

an income dividend or capital gains distribution is sometimes known as "buying a dividend."

Taxes

Fund distributions—The Fund expects, based on its investment objective and strategies, that its distributions, if any, will be taxable as ordinary income, capital gains, or some combination of both. This is true whether you reinvest your distributions in additional Fund shares or receive them in cash.

For federal income tax purposes, Fund distributions of short-term capital gains are taxable to you as ordinary income. Fund distributions of long-term capital gains are taxable to you as long-term capital gains no matter how long you have owned your shares. With respect to taxable years of the Fund beginning before January 1, 2013, unless such provision is extended, possibly retroactively to January 1, 2013, or made permanent, a portion of income dividends reported by the Fund may be qualified dividend income eligible for taxation by individual shareholders at long-term capital gain rates, provided certain holding period requirements are met.

Sale or redemption of Fund shares—If you are a taxable investor, when you sell or redeem your shares in the Fund, you may realize a capital gain or loss. For tax purposes, an exchange of your Fund shares for shares of a different Family Fund is the same as a sale. Any loss incurred on the sale or exchange of Fund shares held for six months or less will be treated as a long-term capital loss to the extent of capital gain distributions received with respect to such shares. Beginning with the 2012 calendar year, the Fund will be required to report to you and the IRS annually on Form 1099-B not only the gross proceeds of Fund shares you sell or redeem but also their cost basis for shares purchased or acquired on or after January 1, 2012 ("covered shares"). Cost basis will be calculated using the Fund's default method of average cost, unless you instruct the Fund to use a different calculation method. Shareholders should carefully review the cost basis information provided by the Fund and make any additional basis, holding period or other adjustments that are required when reporting these amounts on their federal income tax returns. If your account is held by your investment representative (financial advisor or other broker), please contact that representative with respect to reporting of cost basis and available elections for your account. Their default

26

The UBS Funds

method for cost basis reporting may be different than the Fund's default method. Tax-advantaged retirement accounts will not be affected.

Medicare tax—For taxable years beginning after December 31, 2012, an additional 3.8% Medicare tax will be imposed on certain net investment income (including ordinary dividends and capital gain distributions received from the Fund and net gains from redemptions or other taxable dispositions of Fund shares) of US individuals, estates and trusts to the extent that such person's "modified adjusted gross income" (in the case of an individual) or "adjusted gross income" (in the case of an estate or trust) exceeds a threshold amount.

Backup withholding—By law, if you do not provide the Fund with your proper taxpayer identification number and certain required certifications, you may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of your shares. The Fund also must withhold if the IRS instructs it to do so. When withholding is required, the amount will be 28% of any distributions or proceeds paid (for distributions and proceeds paid on or after January 1, 2013, the rate is scheduled to rise to 31% unless the 28% rate is extended, possibly retroactively to January 1, 2013, or made permanent).

State and local taxes—Fund distributions and gains from the sale or exchange of your Fund shares generally are subject to state and local taxes.

Non-US investors—Non-US investors may be subject to US withholding tax at a 30% or lower treaty rate and US estate tax and are subject to special US tax certification requirements to avoid backup withholding and claim any treaty benefits. An exemption from US withholding tax is provided for capital gain dividends paid by the Fund from long-term capital gains, if any. However, notwithstanding such exemption from US withholding at the source, any such dividends and distributions of income and capital gains will be subject to backup withholding at a rate of 28% (or the then applicable rate) if you fail to properly certify that you are not a US person.

Other reporting and withholding requirements. The Foreign Account Tax Compliance Act ("FATCA") requires the reporting to the IRS of certain direct and indirect ownership of foreign financial accounts by US persons. Failure to provide this required information can result in a 30% withholding tax on payments of US source income made to shareholders that are "foreign financial institutions" or certain "non-financial foreign entities." For more information, please see the discussion regarding FATCA in the SAI.

This discussion of "Dividends and Taxes" is not intended or written to be used as tax advice. Because everyone's tax situation is unique, you should consult your tax professional about federal, state, local or foreign tax consequences before making an investment in the Fund.

UBS Global Asset Management, Americas Region

Business continuity planning overview

UBS Global Asset Management affiliates UBS Global Asset Management (US) and UBS Global Asset Management (Americas) will protect information assets, processes, and customer data from unpredictable events through preparation and testing of a comprehensive business continuity capability. This capability seeks recovery of the technology infrastructure and information, and prevention of the loss of company or customer information and transactions. In the event of a crisis scenario, we will recover those functions deemed to be critical to our business and our clients, and strive to resume processing within predefined time frames following a disaster declaration (typically 24-36 hours). Business continuity processes will provide us the ability to continue critical business functions regardless of the type, scope, or duration of a localized event. However, these processes are dependent upon various external resources beyond our control, such as regional telecommunications, transportation networks, and other public utilities.

Essential elements of the business continuity plan include:

•  Crisis communication procedures—Action plans for coordinating essential communications for crisis management leaders, employees, and key business partners

•  Information technology backup and recovery procedures—Comprehensive technology and data management plans designed to protect the integrity and speed the recovery of essential technology infrastructure and data

•  Disaster recovery site—Alternative workspace, technology infrastructure, and systems support that is designed to be fully operational within 24-36 hours of a disaster declaration

•  Testing regimen—The business continuity plan is reviewed on a quarterly basis and tested on an annual basis, including full activation of the disaster recovery facility.

Investment strategies

The following discussion of investment techniques and instruments supplements and should be read in conjunction with the investment objectives and policies set forth in the Fund's Prospectus. The investment practices described below, except for the discussion of percentage limitations with respect to portfolio loan transactions and borrowing, are not fundamental and may be changed by the Board without the approval of the shareholders.

Investments relating to the Fund

Cash and cash equivalents

The Fund may invest a portion of its assets in short-term debt securities (including repurchase agreements and reverse repurchase agreements) of corporations, governments and their agencies and instrumentalities and banks and finance companies, which may be denominated in any currency. The Fund may also invest a portion of its assets in shares issued by money market mutual funds. When unusual market conditions warrant, the Fund may make substantial temporary defensive investments in cash equivalents up to a maximum of 100% of its net assets. Non-US dollar-denominated cash equivalent holdings may not constitute "cash or cash equivalents" for tax diversification purposes under the Code. When the Fund invests for defensive purposes, it may affect the attainment of the Fund's investment objective.

Pursuant to the rules and regulations under the Act and any exemptive orders issued thereunder, the Fund may invest cash: (i) held for temporary defensive purposes; (ii) not invested pending investment in securities; (iii) that is set aside to cover an obligation or commitment of the Fund to purchase securities or other assets at a later date; and (iv) to be invested on a strategic management basis, in a series of shares of UBS Relationship Funds ("Relationship Funds Cash Series"). UBS Relationship Funds is a registered investment company advised by the Advisor. The Trustees of the Trust also serve as Trustees of UBS Relationship Funds. The Relationship Funds Cash Series invests in US dollar denominated money market instruments having a dollar-weighted average maturity of 60 days or less, and operates in accordance with Rule 2a-7 under the Act.

Repurchase agreements

When the Fund enters into a repurchase agreement, it purchases securities from a bank or broker-dealer, which simultaneously agrees to repurchase the securities at a mutually agreed upon time and price, thereby determining the yield during the term of the agreement. As a result, a repurchase agreement provides a fixed rate of return insulated from market fluctuations during the term of the agreement. The term of a repurchase agreement generally is short, possibly overnight or for a few days, although it may extend over a number of months (up to one year) from the date of delivery. Repurchase agreements are considered under the Act to be collateralized loans by the Fund to the seller secured by the securities transferred to the Fund. In accordance with the Act, repurchase agreements will be fully collateralized and the collateral will be marked-to-market daily. The Fund may not enter into a repurchase agreement having more than seven days

5

remaining to maturity if, as a result, such agreement, together with any other illiquid securities held by the Fund, would exceed 15% of the value of the net assets of the Fund.

Repurchase agreements are securities for purposes of the tax diversification requirements that must be met for pass-through treatment under the Code. Accordingly, the Fund will limit the value of its repurchase agreements on each of the quarterly testing dates to ensure compliance with Subchapter M of the Code.

Reverse repurchase agreements

Reverse repurchase agreements involve sales of portfolio securities of the Fund to member banks of the Federal Reserve System or securities dealers believed creditworthy, concurrently with an agreement by the Fund to repurchase the same securities at a later date at a fixed price that is generally equal to the original sales price plus interest. The Fund retains record ownership and the right to receive interest and principal payments on the portfolio securities involved. In connection with each reverse repurchase transaction, the Fund's custodian will maintain Segregated Assets in an amount equal to the repurchase price (inclusive of interest charges). The cover amount for a reverse repurchase agreement which lacks a specified repurchase price is an amount equal to the value of the proceeds received on any sale subject to repurchase plus accrued interest beginning on the date the Fund enters into the reverse repurchase agreement.

A reverse repurchase agreement involves the risk that the market value of the securities retained by the Fund may decline below the price of the securities the Fund has sold but is obligated to repurchase under the agreement. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, the Fund's use of the proceeds of the agreement may be restricted pending a determination by the other party, or its trustee or receiver, whether to enforce the Fund's obligation to repurchase the securities. Reverse repurchase agreements are considered borrowings by the Fund and as such, are subject to the same investment limitations.

Borrowing

The Fund may borrow money for temporary emergency or extraordinary purposes, or to facilitate redemptions. The Fund may also borrow money for investment purposes. The Fund will not borrow money in excess of 33¹/₃% of the value of its total assets (including amounts borrowed, but reduced by any liabilities not constituting senior securities). Any borrowing will be done from a bank with the required asset coverage of at least 300%. In the event that such asset coverage shall at any time fall below 300%, the Fund shall, within three days thereafter (not including Sundays or holidays), or such longer period as the SEC may prescribe by rules and regulations, reduce the amount of its borrowings to such an extent that the asset coverage of such borrowings shall be at least 300%. The Fund will not pledge more than 10% of its net assets, or issue senior securities as defined in the Act, except for notes to banks and reverse repurchase agreements.

Segregation of assets—Consistent with SEC staff guidance, financial instruments that involve the Fund's obligation to make future payments to third parties will not be viewed as creating any senior security provided that the Fund covers its obligations as described below. Those financial instruments can include, among others, (i) reverse repurchase agreements, (ii) when-issued and delayed delivery securities, (iii) dollar rolls, (iv) to-be-announced securities, (v) securities sold short (vi) swaps, (vii) futures contracts, (viii) written options, (ix) forward currency contracts, and (x) non-deliverable forwards.

Consistent with SEC staff guidance, the Fund will consider its obligations involving such a financial instrument as "covered" when the Fund (1) maintains an offsetting financial position, or (2) segregates liquid assets (which include, but are not limited to, cash, cash equivalents, equities and debt instruments of any grade) equal to the Fund's exposures relating to the financial instrument, as determined on a daily basis. Dedicated Fund compliance policies and procedures, which the Trust's Board has approved, govern the kinds of

6

transactions that can be deemed to be offsetting positions for purposes of (1) above, and the amounts of assets that need to be segregated for purposes of (2) above (segregated assets procedures). Any assets designated as segregated by the Fund, either physically or "earmarked" as segregated, for purposes of (2) above shall be liquid, unencumbered and marked-to-market daily (any such assets designated as segregated, either physically or "earmarked" as segregated, are referred to in this SAI as "Segregated Assets"), and such Segregated Assets shall be maintained in accordance with pertinent positions of the SEC.

The Fund's segregated assets procedures may require the Fund to sell a portfolio security or exit a transaction, including a transaction in a financial instrument, at a disadvantageous time or price in order for the Fund to be able to segregate the required amount of assets. If Segregated Assets decline in value, the Fund will need to segregate additional assets or reduce its position in the financial instruments. In addition, Segregated Assets may not be available to satisfy redemptions or for other purposes, until the Fund's obligations under the financial instruments have been satisfied. In addition, the Fund's ability to use the financial instruments identified above may under some circumstances depend on the nature of the instrument and amount of assets that the segregated assets procedures require the Fund to segregate. The segregated assets procedures provide, consistent with current SEC staff positions, that for futures and forward contracts that require only cash settlement, and swap agreements that call for periodic netting between the Fund and its counterparty, the segregated amount is the net amount due under the contract, as determined daily on a mark-to-market basis. For other kinds of futures, forwards and swaps, the Fund must segregate a larger amount of assets to cover its obligations, which essentially limits the Fund's ability to use these instruments. If the SEC staff changes its positions concerning the segregation of the net amount due under certain forwards, futures and swap contracts, the ability of the Fund to use the financial instruments could be negatively affected.

When the Fund borrows money for investment purposes, it is engaging in a form of leverage, which increases investment risk while increasing investment opportunity. The money borrowed for such leveraging purposes will be subject to interest costs which may or may not be recovered by appreciation of the securities purchased and may exceed the income from the securities purchased.

Loans of portfolio securities

The Fund may lend portfolio securities to qualified broker-dealers and financial institutions pursuant to agreements, provided the following conditions are satisfied: (1) the loan is secured continuously by collateral marked-to-market daily as described below; (2) the Fund may call the loan at any time and receive the securities loaned; (3) the Fund will receive any interest, dividends or other distributions paid on the loaned securities; and (4) the aggregate market value of securities loaned will not at any time exceed 33¹/₃% of the market value of the Fund's total assets. However, as a non-fundamental policy, the Fund may not enter into a securities loan if, after giving effect thereto, portfolio securities having a value in excess of 30% of the market value of the Fund's total assets would be subject to securities loans.

When loaning portfolio securities, the Fund will initially require the borrower to provide the Fund with collateral in an amount at least equal to 102% of the market value of the loaned securities with respect to domestic securities and 105% of the market value of the loaned securities with respect to foreign securities. Thereafter, collateral will generally be maintained in an amount at least equal to 102% of the value of the securities loaned with respect to domestic securities and 105% of the value of the securities loaned with respect to foreign securities. Occasionally, for certain securities, the market value of the collateral may fall below the collateral amount stated above by a de minimis amount for a period of time. However, at no time will the market value of the collateral fall below the market value of the loaned securities with respect to domestic securities or 102% of the value of the loaned securities with respect to foreign securities.

7

Collateral may consist of cash, US government or government agency securities or, under certain conditions, bank letters of credit. Pursuant to rules and regulations under the Act, under normal conditions, the Fund invests cash collateral from securities lending activities into an affiliated private money market fund, UBS Private Money Market Fund, LLC, which operates in compliance with most of the substantive provisions of Rule 2a-7 of the Act. In addition, cash collateral may be invested in repurchase agreements.

In the case that voting or consent rights that accompany a loaned security pass to the borrower, the Fund will recall the loaned security to permit the exercise of such rights if the matter involved would have a material effect on the Fund's investment in the security.

Loans of securities involve a risk that the borrower may fail to return the securities or may fail to maintain the proper amount of collateral, which may result in a loss of money by the Fund or a delay in recovering the loaned securities. In addition, in the event of bankruptcy of the borrower, the Fund could experience delays in recovering the loaned securities or only recover cash or a security of equivalent value. Therefore, the Fund will only enter into portfolio loans after a review of all pertinent factors by the Advisor under the supervision of the Board, including the creditworthiness of the borrower and then only if the consideration to be received from such loans would justify the risk. Creditworthiness will be monitored on an ongoing basis by the Advisor.

Swaps

The Fund may engage in swaps, including, but not limited to, interest rate, currency and total return swaps, and the purchase or sale of related caps, floors, collars and other derivative instruments. The Fund expects to enter into these transactions to preserve a return or spread on a particular investment or portion of the portfolio's duration, to protect against any increase in the price of securities the Fund anticipates purchasing at a later date, or to gain exposure to certain markets or returns in the most economical way possible.

Interest rate swaps involve the exchange by the Fund with another party of their respective commitments to receive or pay interest (e.g., an exchange of fixed rate payments for floating rate payments) with respect to a notional amount of principal. Currency swaps involve the exchange of cash flows on a notional amount based on changes in the values of referenced currencies.

The purchase of a cap entitles the purchaser to receive payments on a notional principal amount from the party selling the cap to the extent that a specified index exceeds a predetermined interest rate or amount. The purchase of an interest rate floor entitles the purchaser to receive payments on a notional principal amount from the party selling the floor to the extent that a specified index falls below a predetermined interest rate or amount. A collar is a combination of a cap and a floor that preserves a certain return with a predetermined range of interest rates or values.

The use of swaps involves investment techniques and risks different from those associated with ordinary portfolio security transactions. If the Advisor is incorrect in its forecast of market values, total return of securities, interest rates and other applicable factors, the investment performance of the Fund will be less favorable than it would have been if this investment technique was never used. Swaps do not involve the delivery of securities or other underlying assets or principal, and are subject to counterparty risk. If the other party to a swap defaults and fails to consummate the transaction, the Fund's risk of loss consists of the net amount of interest payments that the Fund is contractually entitled to receive.

If there is a default by the counterparty to a swap contract, the Fund will be limited to contractual remedies pursuant to the agreements related to the transaction. There is no assurance that a swap contract counterparty will be able to meet its obligations pursuant to the swap contract or that, in the event of a

8

default, the Fund will succeed in pursuing contractual remedies. The Fund thus assumes the risk that it may be delayed in or prevented from obtaining payments owed to it pursuant to a swap contract. However, the amount at risk is only the net unrealized gain, if any, on the swap, not the entire notional amount. The Advisor will closely monitor, subject to the oversight of the Board, the creditworthiness of swap counterparties in order to minimize the risk of swaps.

Total return swap contracts are agreements between two parties where one counterparty pays the other the total return of a particular instrument (e.g., a specified security, basket of securities or securities indices, including real estate market indices, during the specified period) in return for periodic payments based on a fixed or variable interest rate, typically at a floating rate based on LIBOR, or the total rate of return on another financial instrument. The "total return" includes interest payments from, along with any change in value of, the referenced asset over a specified period. The Fund will enter into total return swap contracts only on a net basis, i.e., the two parties' obligations are netted out, with the Fund paying or receiving, as the case may be, only the net amount of the payments. Total return swap contracts may be used to obtain exposure to a security or market without owning or taking physical custody of such security or investing directly in such market. The value of the swap position as well as the payments required to be made by the Fund or a counterparty will increase or decrease depending on the changes in value of the underlying asset. Total return swap contracts may effectively add leverage to the Fund's portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap.

Total return swap transactions involve greater risks than if the Fund had invested in the underlying asset directly. Total return swap transactions involve counterparty risks, as discussed above, but also involve additional risks, including interest rate risk and market risk. The total rate of return of an investment on which a total return swap contract is based may exhibit substantial volatility and, in any given period, may be positive or negative for the specified period of the total return swap contract. If the Advisor is incorrect in its forecast of the underlying asset's total return, the investment performance of the Fund will be less favorable than it would have been if this investment technique was never used. In the event the total rate of return of the underlying asset is negative for the specified period of the swap contract, the Fund will be required to make a payment to the counterparty in addition to the periodic payment required by the swap contract to cover the decline in value of the underlying asset. The Fund's risk of loss, therefore, is increased because the Fund could lose an amount equal to the decrease in value of the underlying asset for the specified period of time, in addition to the periodic payments required by the total return swap contract.

The Fund may also purchase swaptions. An option on a swap agreement, also called a "swaption," is an option that gives the buyer the right, but not the obligation, to enter into a swap on a future date in exchange for paying a market-based "premium." A receiver swaption gives the owner the right to receive the total return of a specified asset, reference rate, or index. A payer swaption gives the owner the right to pay the total return of a specified asset, reference rate, or index. Swaptions also include options that allow an existing swap to be terminated or extended by one of the counterparties.

The Advisor and the Trust do not believe that the Fund's obligations under swap contracts are senior securities and, accordingly, the Fund will not treat them as being subject to the Fund's borrowing or senior securities restrictions. Generally, the minimum cover amount for a swap agreement is the amount owed by a Fund, if any, on a daily mark-to-market basis. With respect to swap contracts that provide for the netting of payments, the net amount of the excess, if any, of the Fund's obligations over its entitlements with respect to each swap contract will be accrued on a daily basis and an amount of Segregated Assets having an aggregate market value at least equal to the accrued excess will be maintained to cover the transactions in accordance with SEC positions. With respect to swap contracts that do not provide for the netting of payments by the counterparties, the full notional amount for which the Fund is obligated under the swap

9

contract with respect to each swap contract will be accrued on a daily basis and an amount of Segregated Assets having an aggregate market value at least equal to the accrued full notional value will be maintained to cover the transactions in accordance with SEC positions. When the Fund sells protection on an individual credit default swap, upon a credit event, the Fund may be obligated to deliver the underlying credit or pay the cash equivalent value of the asset. Therefore, the cover amount includes the notional value of the underlying credit on a daily mark-to-market basis. With regard to selling protection on an index (CDX), as a practical matter, the Fund would not be required to pay the full notional amount of the index; therefore, only the amount owed by the Fund, if any, on a daily mark-to-market basis is required as cover. Swaps are generally executed pursuant to agreements that provide for the pledging or deposit of liquid assets collateral. Where liquid assets have been pledged or deposited in accordance with Rule 17f-1 under the Act, the cover amount will be less any assets pledged or deposited as collateral in connection with the swap. To the extent that the Fund cannot dispose of a swap in the ordinary course of business within seven days at approximately the value at which the Fund has valued the swap, the Fund will treat the swap as illiquid and subject to its overall limit on illiquid investments of 15% of the Fund's net assets.

Futures

The Fund may enter into contracts for the purchase or sale for future delivery of securities and indices. The Fund may also enter into contracts for the purchase or sale for future delivery of foreign currencies.

A purchase of a futures contract means the acquisition of a contractual right to obtain delivery to the Fund of the securities or foreign currency called for by the contract at a specified price during a specified future month. When a futures contract is sold, the Fund incurs a contractual obligation to deliver the securities or foreign currency underlying the contract at a specified price on a specified date during a specified future month.

When the Fund enters into a futures transaction, it must deliver to the futures commission merchant (an "FCM") selected by the Fund, an amount referred to as "initial margin." The initial margin is required to be deposited in cash or government securities with an FCM. Minimum initial margin requirements are established by the futures exchange and FCMs may establish initial margin requirements that are higher than the exchange requirements. After a futures contract position is opened, the value of the contract is marked-to-market daily. If a futures contract price changes to the extent that the margin deposit does not satisfy margin requirements, payment of a "variation margin" to be held by the FCM, will be required. Conversely, a reduction in the contract value may reduce the required margin, resulting in a repayment of excess margin to the custodial accounts of the Fund. The Fund may also effect futures transactions through FCMs who are affiliated with the Advisor or the Fund in accordance with procedures adopted by the Board.

The Fund will enter into futures transactions on domestic exchanges and, to the extent such transactions have been approved by the Commodity Futures Trading Commission for sale to customers in the United States, on foreign exchanges. In addition, the Fund may sell stock index futures in anticipation of or during a market decline to attempt to offset the decrease in market value of their common stocks that might otherwise result; and they may purchase such contracts in order to offset increases in the cost of common stocks that they intend to purchase. Unlike other futures contracts, a stock index futures contract specifies that no delivery of the actual stocks making up the index will take place. Instead, settlement in cash must occur upon the termination of the contract.

While futures contracts provide for the delivery of securities, deliveries usually do not occur. Futures contracts can be terminated by entering into offsetting transactions. In addition, the Fund may invest in futures contacts that are contractually required to be "cash-settled," rather than requiring the delivery of the securities. The Fund will cover its obligations under the futures transactions in which it participates by either (i) holding

10

offsetting positions that appropriately equal the daily market value of the Fund's position in the futures contract (less the initial margin and any variation margins deposited with an FCM); or (ii) accruing such amounts on a daily basis and maintaining Segregated Assets to cover the futures contract. With respect to a futures contract that is not contractually required to "cash-settle," the Fund must cover its open position by maintaining Segregated Assets equal to the contract's full, notional value. However, the Fund may net non-cash settled futures contracts if the futures have the same expiration date and underlying instruments. With respect to a futures contract that is contractually required to "cash-settle" the Fund is permitted to maintain Segregated Assets in an amount equal to the Fund's daily marked-to-market (net) obligation (i.e., the Fund's daily net liability if any) rather than the notional value (in other words, the initial margin plus any variation margin (unrealized loss) due based on the previous day's trading). The total cover required for all cash-settled futures contracts may be determined by netting the aggregate obligations of such contracts. By setting aside assets equal to only its net obligation under cash-settled future contracts the Fund will have the ability to employ leverage to a greater extent than if the Fund were required to segregate assets equal to the full notional value of such contracts. The value of any liquid assets held as initial or variation margin with an FCM for a cash-settled or non-settled futures contract may be deemed physically segregated or earmarked for "cover" purposes so long as such assets are held in compliance with Rule 17f-6 under the 1940 Act.

The Fund may enter into futures contracts to protect against the adverse effects of fluctuations in security prices, interest rates or foreign exchange rates without actually buying or selling the securities or foreign currency. For example, if interest rates are expected to increase, the Fund might enter into futures contracts for the sale of debt securities. Such a sale would have much the same effect as selling an equivalent value of the debt securities owned by the Fund. If interest rates did increase, the value of the debt securities in the portfolio would decline, but the value of the futures contracts to the Fund would increase at approximately the same rate, thereby keeping the net asset value of the Fund from declining as much as it otherwise would have. Similarly, when it is expected that interest rates may decline, futures contracts may be purchased to hedge in anticipation of subsequent purchases of securities at higher prices. Since fluctuations in the value of futures contracts should be similar to those of debt securities, the Fund could take advantage of the anticipated rise in value of debt securities without actually buying them until the market had stabilized. At that time, the futures contracts could be liquidated and the Fund could then buy debt securities on the cash market. The Fund may also enter into futures contracts as a low cost method for gaining or reducing exposure to a particular currency or securities market without directly investing in those currencies or securities.

To the extent that market prices move in an unexpected direction, the Fund may not achieve the anticipated benefits of futures contracts or may realize a loss. For example, if the Fund is hedged against the possibility of an increase in interest rates, which would adversely affect the price of securities held in its portfolio, and interest rates decrease instead, the Fund would lose part or all of the benefit of the increased value that it has because it would have offsetting losses in its futures position. In addition, in such situations, if the Fund had insufficient cash, it may be required to sell securities from its portfolio to meet daily variation margin requirements. Such sales of securities may, but will not necessarily, be at increased prices that would reflect the rising market. The Fund may be required to sell securities at a time when it may be disadvantageous to do so.

Options

The Fund may purchase and write call or put options on foreign or US securities and indices and enter into related closing transactions. The Fund may also purchase exchange-listed call options on particular market segment indices to achieve temporary exposure to a specific industry.

The Fund may invest in options that are either listed on US or recognized foreign exchanges or traded over-the-counter. The Fund may use both European-style options, which have a single exercise date typically

11

on expiration, and American-style options, which are exercisable at any time prior to the expiration date. The Fund may also enter into options that are cash-settled based on the exercise price of the option. Certain over-the-counter options may be illiquid. Thus, it may not be possible to close options positions and this may have an adverse impact on the Fund's ability to effectively hedge its securities. The Trust has been notified by the SEC that it considers over-the-counter options to be illiquid. Accordingly, the Fund will only invest in such options to the extent consistent with its 15% limit on investments in illiquid securities.

Purchasing call options—The Fund may purchase call options on securities to the extent that premiums on all outstanding call options paid by the Fund do not aggregate to more than 20% of the Fund's total assets. When the Fund purchases a call option, in return for a premium paid by the Fund to the writer of the option, the Fund obtains the right to buy the security underlying the option at a specified exercise price at any time during the term of the option. The writer of the call option, who receives the premium upon writing the option, has the obligation upon exercise of the option, to deliver the underlying security against payment of the exercise price. The advantage of purchasing call options is that the Fund may alter portfolio characteristics and modify portfolio maturities without incurring the cost associated with transactions.

The Fund may, following the purchase of a call option, liquidate its position by effecting a closing sale transaction. This is accomplished by selling an option of the same series as the option previously purchased. The Fund will realize a profit from a closing sale transaction if the price received on the transaction is more than the premium paid to purchase the original call option; the Fund will realize a loss from a closing sale transaction if the price received on the transaction is less than the premium paid to purchase the original call option.

Although the Fund will generally purchase only those call options for which there appears to be an active secondary market, there is no assurance that a liquid secondary market on an exchange will exist for any particular option, or at any particular time, and for some options no secondary market on an exchange may exist. In such an event, it may not be possible to effect closing transactions in particular options, with the result that the Fund would have to exercise its options in order to realize any profit and would incur brokerage commissions upon the exercise of such options and upon the subsequent disposition of the underlying securities acquired through the exercise of such options. Further, unless the price of the underlying security changes sufficiently, a call option purchased by the Fund may expire without any value to the Fund, in which event the Fund would realize a capital loss, which will be short-term unless the option was held for more than one year.

Call writing—The Fund may write call options from time to time on such portions of its portfolio, without limit, as the Advisor determines is appropriate in seeking to achieve the Fund's investment objective. The advantage to the Fund in writing calls is that the Fund receives a premium, which is an additional cash payment. However, if the security rises in value, the Fund may not fully participate in the market appreciation.

With certain types of options, during the option period for a call option, the writer may be assigned an exercise notice by the broker-dealer through whom such call option was sold, requiring the writer to deliver the underlying security against payment of the exercise price. This obligation is terminated upon the expiration of the option or upon entering a closing purchase transaction. A closing purchase transaction, in which the Fund, as writer of an option, terminates its obligation by purchasing an option of the same series as the option previously written, cannot be effected once the option writer has received an exercise notice for such option.

Closing purchase transactions will ordinarily be effected to realize a profit on an outstanding call option, to prevent an underlying security from being called, to permit the sale of the underlying security or to enable the Fund to write another call option on the underlying security with either a different exercise price, expiration date or both. The Fund may realize a net gain or loss from a closing purchase transaction depending upon

12

whether the net amount of the original premium received on the call option is more or less than the cost of effecting the closing purchase transaction. Any loss incurred in a closing purchase transaction may be partially or entirely offset by the premium received from a sale of a different call option on the same underlying security. Such a loss may also be wholly or partially offset by unrealized appreciation in the market value of the underlying security. Conversely, a gain resulting from a closing purchase transaction could be offset in whole or in part by a decline in the market value of the underlying security.

If a call option expires unexercised, the Fund will realize a short-term capital gain in the amount of the premium on the option less the commission paid. Such a gain, however, may be offset by depreciation in the market value of the underlying security during the option period. If a call option is exercised, the Fund will realize a gain or loss from the sale of the underlying security equal to the difference between the cost of the underlying security and the proceeds of the sale of the security plus the amount of the premium on the option less the commission paid.

The Fund will generally write call options on a covered basis. A call option written by the Fund is "covered" if the Fund owns the underlying security covered by the call or has an absolute and immediate right to acquire that security without additional cash consideration (or for additional cash consideration maintained as Segregated Assets by the Fund's custodian) upon conversion or exchange of other securities held by the Fund. A call option is also deemed to be covered if the Fund holds a call on the same security and in the same principal amount as the call written and the exercise price of the call held (i) is equal to or less than the exercise price of the call written or (ii) is greater than the exercise price of the call written if the difference is maintained as Segregated Assets by the Fund's custodian.

From time to time, the Fund will write a call option that is not covered as indicated above, but where the Fund's custodian will maintain Segregated Assets for the term of the option having a value equal to the fluctuating market value of the optioned securities or currencies, marked-to-market daily, in accordance with SEC positions. While such an option would be "covered" with sufficient collateral to satisfy SEC prohibitions on issuing senior securities, this type of strategy would expose the Fund to the risks of writing uncovered options. When writing uncovered call options, the Fund is subject to the risk of having to purchase the security or currency subject to the option at a price higher than the exercise price of the option. As the price of a security or currency could appreciate substantially, the Fund's loss could be significant.

Purchasing put options—The Fund may only purchase put options to the extent that the premiums on all outstanding put options do not exceed 20% of the Fund's total assets. The Fund will, at all times during which it holds a put option, own the security covered by such option.

A put option purchased by the Fund gives it the right to sell one of its securities for an agreed price up to an agreed date. The Fund intends to purchase put options in order to protect against a decline in the market value of the underlying security below the exercise price less the premium paid for the option ("protective puts"). The ability to purchase put options will allow the Fund to protect unrealized gains in an appreciated security in its portfolio without actually selling the security. If the security does not drop in value, the Fund will lose the value of the premium paid. The Fund may sell a put option that it has previously purchased prior to the sale of the securities underlying such option. Such sale will result in a net gain or loss depending on whether the amount received on the sale is more or less than the premium and other transaction costs paid on the put option that is sold.

The Fund may sell put options purchased on individual portfolio securities. Additionally, the Fund may enter into closing sale transactions. A closing sale transaction is one in which the Fund, when it is the holder of an

13

outstanding option, liquidates its position by selling an option of the same series as the option previously purchased.

Writing put options—The Fund may also write put options on a secured basis, which means that the Fund's custodian will maintain Segregated Assets in an amount not less than the exercise price of the option at all times during the option period. The amount of Segregated Assets will be adjusted on a daily basis to reflect changes in the market value of the securities covered by the put option written by the Fund. Secured put options will generally be written in circumstances where the Advisor wishes to purchase the underlying security for the Fund's portfolio at a price lower than the current market price of the security. In such event, the Fund would write a secured put option at an exercise price, which, reduced by the premium received on the option, reflects the lower price it is willing to pay.

Following the writing of a put option, the Fund may wish to terminate the obligation to buy the security underlying the option by effecting a closing purchase transaction. This is accomplished by buying an option of the same series as the option previously written. The Fund may not, however, effect such a closing transaction after it has been notified of the exercise of the option.

Index options

The Fund may purchase call options on stock indices and sell such options in closing sale transactions for hedging purposes. The Fund also may purchase call options on indices primarily as a substitute for taking positions in certain securities or a particular market segment. The Fund may also purchase call options on an index to protect against increases in the price of securities underlying that index that the Fund intends to purchase pending its ability to invest in such securities.

In addition, the Fund may purchase put options on stock indices and sell such options in closing sale transactions. The Fund may purchase put options on broad market indices in order to protect its fully invested portfolio from a general market decline. Put options on market segments may be bought to protect the Fund from a decline in the value of heavily weighted industries in the Fund's portfolio. Put options on stock indices may also be used to protect the Fund's investments in the case of a major redemption.

The Fund may also write (sell) put and call options on stock indices. While the option is open, the Fund's custodian will maintain Segregated Assets to cover the transactions, marked-to-market daily in accordance with SEC positions.

Options on indices are similar to regular options except that an option on an index gives the holder the right, upon exercise, to receive an amount of cash if the closing level of the index upon which the option is based is greater than (in the case of a call) or lesser than (in the case of a put) the exercise price of the option. This amount of cash is equal to the difference between the closing price of the index and the exercise price of the option expressed in dollars multiplied by a specified multiple (the "multiplier"). The indices on which options are traded include both US and non-US markets.

Special risks of options on indices

The Fund's purchases of options on indices will subject it to the risks described below.

Because the value of an index option depends upon movements in the level of the index rather than the price of a particular security, whether the Fund will realize gain or loss on the purchase of an option on an index depends upon movements in the level of prices in the market generally or in an industry or market segment, rather than movements in the price of a particular security. Accordingly, successful use by the Fund of options on indices is subject to the Advisor's ability to predict correctly the direction of movements in the

14

market generally or in a particular industry. This requires different skills and techniques than predicting changes in the prices of individual securities.

Index prices may be distorted if trading of a substantial number of securities included in the index is interrupted causing the trading of options on that index to be halted. If a trading halt occurred, the Fund would not be able to close out options that it had purchased and the Fund may incur losses if the underlying index moved adversely before trading resumed. If a trading halt occurred and restrictions prohibiting the exercise of options were imposed through the close of trading on the last day before expiration, exercises on that day would be settled on the basis of a closing index value that may not reflect current price information for securities representing a substantial portion of the value of the index.

If the Fund holds an index option and exercises it before final determination of the closing index value for that day, it runs the risk that the level of the underlying index may change before closing. If such a change causes the exercised option to fall "out-of-the-money," the Fund will be required to pay the difference between the closing index value and the exercise price of the option (multiplied by the applicable multiplier) to the assigned writer. Although the Fund may be able to minimize this risk by withholding exercise instructions until just before the daily cutoff time or by selling rather than exercising the option when the index level is close to the exercise price, it may not be possible to eliminate this risk entirely because the cutoff times for index options may be earlier than those fixed for other types of options and may occur before definitive closing index values are announced.

Special risks of certain derivatives

Certain derivative contracts entered into by the Funds may contain certain credit-risk-related contingent features that could be triggered subject to certain circumstances. If triggered, the derivative counterparty could request additional cash margin and/or terminate the derivative contract.

Rule 144A and illiquid securities

The Fund may invest in securities that are exempt under Rule 144A from the registration requirements of the 1933 Act. Those securities purchased under Rule 144A are traded among qualified institutional buyers.

The Board has instructed the Advisor to consider the following factors in determining the liquidity of a security purchased under Rule 144A: (i) the security can be sold within seven days at approximately the same amount at which it is valued by the Fund; (ii) there is reasonable assurance that the security will remain marketable throughout the period it is expected to be held by the Fund, taking into account the actual frequency of trades and quotations for the security (expected frequency in the case of initial offerings); (iii) at least two dealers make a market in the security; (iv) there are at least three sources from which a price for the security is readily available; (v) settlement is made in a "regular way" for the type of security at issue; (vi) for Rule 144A securities that are also exempt from registration under Section 3(c)(7) of the Act, there is a sufficient market of "qualified purchasers" (as defined in the Act) to assure that it will remain marketable throughout the period it is expected to be held by the Fund; (vii) the issuer is a reporting company under the Securities Exchange Act of 1934, as amended; and (viii) the security is not in the same class as, or convertible into, any listed security of the issuer. Although having delegated the day-to-day functions, the Board will continue to monitor and periodically review the Advisor's selection of Rule 144A securities, as well as the Advisor's determinations as to their liquidity. Investing in securities under Rule 144A could have the effect of increasing the level of the Fund's illiquidity to the extent that qualified institutional buyers become, for a time, uninterested in purchasing these securities. After the purchase of a security under Rule 144A, however, the Board and the Advisor will continue to monitor the liquidity of that security to ensure that the Fund has no more than 15% of its net assets in illiquid securities.

15

The Fund will limit investments in securities of issuers which the Fund is restricted from selling to the public without registration under the 1933 Act to no more than 15% of the Fund's net assets, excluding restricted securities eligible for resale pursuant to Rule 144A that have been determined to be liquid pursuant to a policy and procedures adopted by the Trust's Board which includes continuing oversight by the Board.

If the Advisor determines that a security purchased in reliance on Rule 144A that was previously determined to be liquid, is no longer liquid and, as a result, the Fund's holdings of illiquid securities exceed the Fund's 15% limit on investment in such securities, the Advisor will determine what action shall be taken to ensure that the Fund continues to adhere to such limitation, including disposing of illiquid assets which may include such Rule 144A securities.

Non-publicly traded securities, private placements and restricted securities

The Fund may invest in securities that are neither listed on a stock exchange nor traded over-the-counter, including privately placed securities and limited partnerships. Investing in unregistered or unlisted securities, including investments in new and early stage companies, may involve a high degree of business and financial risk that can result in substantial losses. As a result of the absence of a public trading market for these securities, they may be less liquid than publicly traded securities. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by the Fund, or less than what may be considered the fair value of such securities. Furthermore, companies whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements that would be applicable if their securities were publicly traded. If such securities are required to be registered under the securities laws of one or more jurisdictions before being resold, the Fund may be required to bear the expense of registration. Investments by the Fund in non-publicly traded securities, private placements and restricted securities will be limited to the Fund's prohibition on investing more than 15% of its net assets in illiquid securities.

Investment company securities and investments in affiliated investment companies

Subject to the provisions of any rules and regulations under the Act or exemptive orders issued thereunder, securities of other investment companies may be acquired by the Fund to the extent that such purchases are consistent with the Fund's investment objective and restrictions and are permitted under the Act. The Act requires that, as determined immediately after a purchase is made, (i) not more than 5% of the value of the Fund's total assets will be invested in the securities of any one investment company, (ii) not more than 10% of the value of the Fund's total assets will be invested in securities of investment companies as a group and (iii) not more than 3% of the outstanding voting stock of any one investment company will be owned by the Fund. Certain exceptions to these limitations may apply. As a shareholder of another investment company, the Fund would bear, along with other shareholders, its pro rata portion of the other investment company's expenses, including advisory fees. These expenses would be in addition to the expenses that the Fund would bear in connection with its own operations.

The Fund may invest in securities issued by other registered investment companies advised by the Advisor, including portfolios of the UBS Relationship Funds, beyond the above percentage maximums pursuant to rules promulgated by the SEC and/or exemptive relief granted by the SEC to the extent that the Advisor determines that such investments are a more efficient means for the Fund to gain exposure to certain asset classes than by the Fund investing directly in individual securities. The Fund may only invest in portfolios of UBS Relationship Funds or other affiliated investment companies to the extent that the asset class exposure in such portfolios is consistent with the permissible asset class exposure for the Fund, had the Fund invested directly in securities, and the portfolios of such investment companies are subject to similar risks and limitations as the Fund.

16

Exchange-traded funds ("ETFs")

Subject to the limitations on investments in investment company securities and its own investment objective, the Fund may invest in securities of ETFs that attempt to track or replicate the performance of a US or foreign market index. The Fund may invest in ETFs that are currently operational and that may be developed in the future. ETFs usually trade on stock exchanges and generally bear certain operational expenses. To the extent the Fund invests in securities of ETFs, the Fund must bear these expenses in addition to the expenses of its own operation.

Investments in ETFs are subject to a variety of risks, including all of the risks of a direct investment in the underlying securities that the ETF holds. For example, the general level of stock prices may decline, thereby adversely affecting the value of the underlying investments of the ETF and, consequently, the value of the ETF. In addition, the market value of the ETF shares may differ from their net asset value because the supply and demand in the market for ETF shares at any point in time is not always identical to the supply and demand in the market for the underlying securities. Also, ETFs that track particular indexes typically will be unable to match the performance of the index exactly due to the ETF's operating expenses and transaction costs.

Real estate investment trusts ("REITs")

The Fund may invest up to 5% of its total assets in equity interests issued by REITs and non-U.S. REIT-like entities (collectively, "REITs"). A REIT is a pooled investment vehicle that purchases primarily income-producing real estate, real estate-related loans or other real estate-related interests. The pooled vehicle, typically a trust, then issues shares whose value and investment performance are dependent upon the investment performance of the underlying real estate-related investments. Generally, REITs can be classified as equity REITs, mortgage REITs or hybrid REITs. Equity REITs invest the majority of their assets directly in real property and derive their income primarily from rents and capital gains from appreciation realized through property sales. Equity REITs are further categorized according to the types of real estate securities they own (e.g., apartment properties, retail shopping centers, office and industrial properties, hotels, health-care facilities, manufactured housing and mixed-property types). Mortgage REITs invest the majority of their assets in real estate mortgages and derive their income primarily from interest payments. Hybrid REITs combine the characteristics of both equity REITs and mortgage REITs. Debt securities issued by REITs are, for the most part, general and unsecured obligations and are subject to risks associated with REITs.

A REIT is not taxed on income distributed to its shareholders if it complies with regulatory requirements relating to its organization, ownership, assets and income, and with a regulatory requirement that it distribute to its shareholders or unitholders at least 90% of its taxable income for each taxable year. In addition, a shareholder in the Fund, by investing in REITs indirectly through the Fund, will bear not only the shareholder's proportionate share of the expenses of the Fund, but also, indirectly, the management expenses of the underlying REITs. REITs are subject to risks related to the specialized skill of their management, changes in value of the properties the REITs own, the quality of any credit extended by the REITs, and general economic and other factors. An investment in REITs includes the possibility of a decline in the value of real estate, possible lack of available money for loans to purchase real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, prolonged vacancies in rental properties, changes in zoning laws, casualty or condemnation losses, variations in rental income, changes in neighborhood values, the appeal of properties to tenants, costs of clean up and liability to third parties resulting from environmental problems, costs associated with damage from natural disasters not covered by insurance, increases in interest rates and changes to tax and regulatory requirements.

In addition, some REITs may have limited diversification and may be subject to risks inherent in investments in a limited number of properties in a narrow geographic area or in a single property type, such as being more susceptible to adverse developments affecting a single project or market segment than more broadly

17

diversified investments. Also, the performance of a REIT may be affected by its failure to qualify for tax-free pass-through of income, or the REIT's failure to maintain exemption from registration under the Act.

Issuer location

The Advisor considers a number of factors to determine whether an investment is tied to a particular country, including whether the investment is issued or guaranteed by a particular government or any of its agencies, political subdivisions or instrumentalities; the investment has its primary trading market in a particular country; the issuer is organized under the laws of, derives at least 50% of its revenues from, or has at least 50% of its assets in a particular country; the investment is included in an index representative of a particular country or region; and the investment is exposed to the economic fortunes and risks of a particular country.

Other investments

The Board may, in the future, authorize the Fund to invest in securities other than those listed in this SAI and in the Prospectus, provided such investment would be consistent with the Fund's investment objective and that it would not violate any fundamental investment policies or restrictions applicable to the Fund.

Equity securities

The Fund may invest in a broad range of equity securities of US and non-US issuers, including, but not limited to, common stocks of companies or closed-end investment companies, preferred stocks, debt securities convertible into or exchangeable for common stock, securities such as warrants or rights that are convertible into common stock and sponsored or unsponsored American, European and Global depositary receipts ("Depositary Receipts"). The issuers of unsponsored Depositary Receipts are not obligated to disclose material information in the United States. The Fund expects its US equity investments to emphasize large and mid capitalization companies. The Fund may also invest in small capitalization companies. The equity markets in the non-US component of the Fund will typically include available shares of larger capitalization companies but may also include intermediate and small capitalization companies. Capitalization levels are measured relative to specific markets, thus large, intermediate and small capitalization ranges vary country by country. The Fund may invest in equity securities of companies considered by the Advisor to be in their post-venture capital stage, or "post-venture capital companies." A post-venture capital company is a company that has received venture capital financing either: (a) during the early stages of the company's existence or the early stages of the development of a new product or service, or (b) as part of a restructuring or recapitalization of the company. The Fund also may invest in the initial public offerings (IPOs) of new or unseasoned companies. The market for IPO shares has been volatile, and share prices of newly public companies have fluctuated significantly over short periods of time.

Special purpose acquisition companies ("SPACs")

The Fund may invest in stock, warrants, and other securities of SPACs or similar special purpose entities that pool funds to seek potential acquisition opportunities. Until an acquisition is completed, a SPAC generally invests its assets in U.S. government securities, money market securities and cash. If an acquisition that meets the requirements for the SPAC is not completed within a pre-established period of time, the funds invested in the SPAC are returned to its shareholders. Because SPACs and similar entities do not have an operating history or ongoing business other than seeking acquisitions, the value of their securities is particularly dependent on the ability of the SPAC's management to identify and complete a profitable acquisition. Some SPACs may pursue acquisitions only within certain industries or regions, which may increase the volatility of their prices. In addition, these securities, which are typically traded in the over-the-counter market, may be considered illiquid and/or be subject to restrictions on resale.

18

Foreign securities

Investors should recognize that investing in foreign issuers involves certain considerations, including those set forth in the Fund's Prospectus, which are not typically associated with investing in US issuers. Since the stocks of foreign companies are frequently denominated in foreign currencies, and since the Fund may temporarily hold uninvested reserves in bank deposits in foreign currencies, the Fund will be affected favorably or unfavorably by changes in currency rates and in exchange control regulations and may incur costs in connection with conversions between various currencies. The investment policies of the Fund permit it to enter into forward foreign currency exchange contracts, futures and options in order to hedge portfolio holdings and commitments against changes in the level of future currency rates.

Investment in the securities of foreign governmental entities involves risk. The governmental entity that controls the repayment of sovereign debt may not be able or willing to repay the principal and/or interest when due in accordance with the terms of such debt. A governmental entity's willingness or ability to repay principal and interest due in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the governmental entity's policy toward the IMF, and the political constraints to which a governmental entity may be subject. Governmental entities may also be dependent on expected disbursements from foreign governments, multilateral agencies and others abroad to reduce principal and interest arrearages on their debt. The commitment on the part of these governments, agencies and others to make such disbursements may be conditioned on a governmental entity's implementation of economic reforms and/or economic performance and the timely service of such debtor's obligations. Failure to implement such reforms, achieve such levels of economic performance or repay principal or interest when due may result in the cancellation of such third parties commitments to lend funds to the governmental entity, which may further impair such debtor's ability or willingness to service its debts in a timely manner. Consequently, governmental entities may default on their sovereign debt. Holders of sovereign debt may be requested to participate in the rescheduling of such debt and to extend further loans to governmental entities. There is no bankruptcy proceeding by which sovereign debt on which governmental entities have defaulted may be collected in whole or in part.

Forward foreign currency contracts

The Fund may purchase or sell currencies and/or engage in forward foreign currency transactions in order to expedite settlement of portfolio transactions, manage currency risk or to gain exposure to a currency without purchasing securities denominated in that currency.

Forward foreign currency contracts are traded in the inter-bank market conducted directly between currency traders (usually large commercial banks) and their customers. A forward contract generally has no deposit requirement and no commissions are charged at any stage for trades. The Fund will account for forward contracts by marking-to-market each day at current forward contract values.

The Fund will enter into forward contracts to sell, for a fixed amount of US dollars or other appropriate currency, an amount of foreign currency, to the extent that the value of the short forward contract is covered by the underlying value of securities denominated in the currency being sold. Alternatively, when the Fund enters into a non-cash settled forward contract, or enters into a cash settled forward contract for a foreign currency for which it does not own securities denominated in that currency, to sell an amount of foreign currency, the Fund's custodian or sub-custodian will maintain Segregated Assets in an amount equal to the contracts' full, notional value. However, currency contracts with respect to identical currencies may be netted against each other and, in such cases, the Fund's custodian or sub-custodian will maintain Segregated Assets in an amount equal to the net amount owed (the unrealized loss) by the Fund.

19

Non-deliverable forwards

The Fund may, from time to time, engage in non-deliverable forward transactions to manage currency risk or to gain exposure to a currency without purchasing securities denominated in that currency. A non-deliverable forward is a transaction that represents an agreement between the Fund and a counterparty (usually a commercial bank) to buy or sell a specified (notional) amount of a particular currency at an agreed upon foreign exchange rate on an agreed upon future date. Unlike other currency transactions, there is no physical delivery of the currency on the settlement of a non-deliverable forward transaction. Rather, the Fund and the counterparty agree to net the settlement by making a payment in US dollars or another fully convertible currency that represents any differential between the foreign exchange rate agreed upon at the inception of the non-deliverable forward agreement and the actual exchange rate on the agreed upon future date. Thus, the actual gain or loss of a given non-deliverable forward transaction is calculated by multiplying the transaction's notional amount by the difference between the agreed upon forward exchange rate and the actual exchange rate when the transaction is completed.

When the Fund enters into a non-deliverable forward transaction, the Fund's custodian will maintain Segregated Assets in an amount not less than the value of the Fund's unrealized loss under such non-deliverable forward transaction. If the additional Segregated Assets decline in value or the amount of the Fund's commitment increases because of changes in currency rates, additional cash or securities will be designated as Segregated Assets on a daily basis so that the value of the account will equal the amount of the Fund's unrealized loss under the non-deliverable forward agreement.

Since the Fund generally may only close out a non-deliverable forward with the particular counterparty, there is a risk that the counterparty will default on its obligation under the agreement. If the counterparty defaults, the Fund will have contractual remedies pursuant to the agreement related to the transaction, but there is no assurance that contract counterparties will be able to meet their obligations pursuant to such agreements or that, in the event of a default, the Fund will succeed in pursuing contractual remedies. The Fund thus assumes the risk that it may be delayed or prevented from obtaining payments owed to it pursuant to non-deliverable forward transactions.

In addition, where the currency exchange rates that are the subject of a given non-deliverable forward transaction do not move in the direction or to the extent anticipated, the Fund could sustain losses on the non-deliverable forward transaction. The Fund's investment in a particular non-deliverable forward transaction will be affected favorably or unfavorably by factors that affect the subject currencies, including economic, political and legal developments that impact the applicable countries, as well as exchange control regulations of the applicable countries. These risks are heightened when a non-deliverable forward transaction involves currencies of emerging market countries because such currencies can be volatile and there is a greater risk that such currencies will be devalued against the US dollar or other currencies.

Options on foreign currencies

The Fund also may purchase and write put and call options on foreign currencies (traded on US and foreign exchanges or over-the-counter markets) to manage the Fund's exposure to changes in currency exchange rates. The Fund may purchase and write options on foreign currencies for hedging purposes in a manner similar to that in which futures contracts on foreign currencies or forward contracts will be utilized. For example, a decline in the dollar value of a foreign currency in which portfolio securities are denominated will reduce the dollar value of such securities, even if their value in the foreign currency remains constant. In order to protect against such diminutions in the value of portfolio securities, the Fund may purchase put options on the foreign currency. If the dollar price of the currency does decline, the Fund will have the right to sell such currency for a fixed amount in dollars and will thereby offset, in whole or in part, the adverse effect on its portfolio which otherwise would have resulted.

20

Conversely, where a rise in the dollar value of a currency in which securities to be acquired are denominated is projected, thereby increasing the dollar price of such securities, the Fund may purchase call options on such currency.

The purchase of such options could offset, at least partially, the effects of the adverse movement in exchange rates. As in the case of other types of options, however, the benefit to the Fund to be derived from purchases of foreign currency options will be reduced by the amount of the premium and related transaction costs. In addition, where currency exchange rates do not move in the direction or to the extent anticipated, the Fund could sustain losses on transactions in foreign currency options that would require it to forego a portion or all of the benefits of advantageous changes in such rates.

The Fund may write options on foreign currencies for the same types of hedging purposes. For example, where the Fund anticipates a decline in the dollar value of foreign currency denominated securities due to adverse fluctuations in exchange rates, it could, instead of purchasing a put option, write a call option on the relevant currency. If the expected decline occurs, the option will most likely not be exercised, and the diminution in the value of portfolio securities will be offset by the amount of the premium received.

Similarly, instead of purchasing a call option to hedge against an anticipated increase in the dollar cost of securities to be acquired, the Fund could write a put option on the relevant currency, which, if rates move in the manner projected, will expire unexercised and allow the Fund to hedge such increased cost up to the amount of the premium. As in the case of other types of options, however, the writing of a foreign currency option will constitute only a partial hedge up to the amount of the premium, and only if rates move in the expected direction. If this does not occur, the option may be exercised and the Fund would be required to purchase or sell the underlying currency at a loss that may not be offset by the amount of the premium. Through the writing of options on foreign currencies, the Fund also may be required to forego all or a portion of the benefit that might otherwise have been obtained from favorable movements in exchange rates.

The Fund may also engage in options transactions for non-hedging purposes. The Fund may use options transactions to gain exposure to a currency when the Advisor believes that exposure to the currency is beneficial to the Fund but believes that the securities denominated in that currency are unattractive.

The Fund may write covered call options on foreign currencies. A call option written on a foreign currency by the Fund is "covered" if the Fund owns the underlying foreign currency covered by the call or has an absolute and immediate right to acquire that foreign currency without additional cash consideration (or for additional cash consideration maintained as Segregated Assets by the Fund's custodian) upon conversion or exchange of other foreign currency held in its portfolio. A call option is also covered if the Fund has a call on the same foreign currency and in the same principal amount as the call written where the exercise price of the call held (a) is equal to or less than the exercise price of the call written, or (b) is greater than the exercise price of the call written if the difference is maintained as Segregated Assets by the Fund's custodian.

With respect to writing put options, at the time the put is written, the Fund's custodian will maintain Segregated Assets in an amount equal in value to the exercise price of the put. The Segregated Assets will be maintained and marked-to-market daily until the put is exercised, has expired or the Fund has purchased a closing put of the same series as the one previously written.

Short sales

The Fund may, from time to time, sell securities short. In a short sale, the Fund sells a security it does not own in anticipation of a decline in the market value of that security. To complete the transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is then obligated to replace the security

21

borrowed by purchasing it at the market price at the time of replacement. Until the security is replaced, the Fund must pay the lender any dividends or interest that accrues during the period of the loan. To borrow the security, the Fund may also be required to pay a premium, which would increase the cost of the security sold. The proceeds of the short sale (which may be invested in equity securities) will be retained by the broker, to the extent necessary to meet margin requirements, until the short position is closed out.

The Fund will incur a loss as a result of the short sale if the price of the security increases between the date of the short sale and the date on which the Fund replaces the borrowed security, and the Fund will realize a gain if the security declines in price between those same dates. The amount of any gain will be decreased, and the amount of any loss increased, by the amount of any premium, dividends or interest the Fund is required to pay in connection with the short sale. Because the Fund's loss on a short sale arises from increases in the value of the security sold short, such loss, like the potential increase in price of the security sold short, is theoretically unlimited. In addition, the Fund's securities held long could decline in value at the same time the value of the security sold short increases, thereby increasing the Fund's potential for loss.

Until the Fund replaces a borrowed security, the Fund will designate Segregated Assets in an amount equal to its obligation to purchase the stocks sold short, as required by law. The amount segregated in this manner will be increased or decreased each business day to equal the change in market value of the Fund's obligation to purchase the security sold short. If the lending broker requires the Fund to deposit additional collateral (in addition to the short sales proceeds that the broker holds during the period of the short sale), the amount of the additional collateral may be deducted in determining the amount of cash or liquid assets the Fund is required to segregate to cover the short sale obligation. The amount segregated must be unencumbered by any other obligation or claim than the obligation that is being covered. The Advisor and the Fund believe that short sale obligations that are covered, either by an offsetting asset or right (acquiring the stock sold short or having an option to purchase the stock sold short at an exercise price that covers the obligation), or by the Fund's Segregated Assets procedures (or a combination thereof), are not senior securities under the Act and are not subject to the Fund's borrowing restrictions. The Fund is also required to repay the lender of the stock any dividends or interest that accrues on the stock during the period of the loan.

Convertible securities

The Fund may invest in convertible securities, which generally offer lower interest or dividend yields than non-convertible debt securities of similar quality. The value of convertible securities may reflect changes in the value of the underlying common stock. Convertible securities entail less credit risk than the issuer's common stock because they rank senior to common stock. Convertible securities entitle the holder to exchange the securities for a specified number of shares of common stock, usually of the same company, at specified prices within a certain period of time and to receive interest or dividends until the holder elects to convert. The provisions of a convertible security determine its ranking in a company's capital structure. In the case of subordinated convertible debentures, the holder's claims on assets and earnings are subordinated to the claims of other creditors but are senior to the claims of preferred and common shareholders. In the case of preferred stock and convertible preferred stock, the holder's claim on assets and earnings are subordinated to the claims of all creditors but are senior to the claims of common shareholders.

Summary of risks

The principal risks of investing in the Fund are described in the "Principal Risks" section of the Prospectus.

22

Investment restrictions

The investment restrictions set forth below are fundamental policies and may not be changed as to the Fund without the approval of a majority of the outstanding voting securities (as defined in the Act) of the Fund. Unless otherwise indicated, all percentage limitations listed below apply to the Fund only at the time of the transaction. Accordingly, if a percentage restriction is adhered to at the time of investment, a later increase or decrease in the percentage that results from a relative change in values or from a change in the Fund's total assets will not be considered a violation. The Fund may not:

(i)  Purchase the securities of any one issuer (other than the US government or any of its agencies or instrumentalities or securities of other investment companies) if immediately after such investment: (a) more than 5% of the value of the Fund's total assets would be invested in such issuer; or (b) more than 10% of the outstanding voting securities of such issuer would be owned by the Fund, except that up to 25% of the value of the Fund's total assets may be invested without regard to such 5% and 10% limitations;

(ii)  Purchase or sell real estate, except that the Fund may purchase or sell securities of real estate investment trusts;

(iii)  Purchase or sell commodities, except that the Fund may purchase or sell currencies, may enter into futures contracts on securities, currencies and other indices or any other financial instruments, and may purchase and sell options on such futures contracts;

(iv)  Issue securities senior to the Fund's presently authorized shares of beneficial interest, except that this restriction shall not be deemed to prohibit the Fund from: (a) making any permitted borrowings, loans or pledges; (b) entering into options, futures contracts, forward contracts, repurchase transactions, or reverse repurchase transactions; or (c) making short sales of securities to the extent permitted by the Act and any rule or order thereunder, or SEC staff interpretations thereof;

(v)  Make loans to other persons, except: (a) through the lending of its portfolio securities; (b) through the purchase of debt securities, loan participations and/or engaging in direct corporate loans for investment purposes in accordance with its investment objectives and policies; (c) to the extent the entry into a repurchase agreement is deemed to be a loan; and (d) the Fund may also make loans to affiliated investment companies to the extent permitted by the Act or any exemptions therefrom that may be granted by the SEC;

(vi)  Borrow money in excess of 33¹/₃% of the value of its assets, except as a temporary measure for extraordinary or emergency purposes to facilitate redemptions. All borrowings will be done from a bank and to the extent that such borrowing exceeds 5% of the value of the Fund's assets, asset coverage of at least 300% is required;

(vii)  Concentrate (invest more than 25% of its net assets) in securities of issuers in a particular industry (other than securities issued or guaranteed by the US government or any of its agencies); and

(viii)  Act as an underwriter, except to the extent the Fund may be deemed to be an underwriter when selling its own shares.

Management of the Trust

Organization of the Board

The Board of Trustees of the Trust is responsible for establishing the Trust's policies and for overseeing the management of the Trust and the Fund. The Board of Trustees elects the officers of the Trust, who, along with third party service providers, are responsible for administering the day-to-day operations of the Trust. The Board of Trustees of the Trust is comprised of six Independent Trustees that are not considered to be "interested persons" by reason of their relationship with the Trust's management or otherwise as defined under the Act and one Interested Trustee who is affiliated with the Advisor. Frank K. Reilly, an Independent Trustee, is Chairman of the Board. As Chairman of the Board, Mr. Reilly approves agendas for Board meetings and generally facilitates communication and coordination among the Independent Trustees and between the Independent Trustees and management. Mr. Reilly also acts as liaison between the Fund's Chief Compliance Officer and the Independent Trustees with respect to compliance matters between scheduled Board meetings.

The Board of the Trust meets in person at least four times each year. At each in-person meeting, the Independent Trustees meet in executive session to discuss matters outside the presence of management. In addition, the Board holds special telephonic meetings throughout the year and the Trustees also discuss other matters on a more informal basis at other times.

The Board has four standing committees, an Audit Committee, a Nominating, Compensation and Governance Committee (the "Nominating Committee"), a Distribution Committee and a Performance Committee. As described below, through these Committees, the Independent Trustees have direct oversight of the Trust's accounting and financial reporting policies, the selection and nomination of candidates to the Trust's Board and the Trust's governance procedures, the distribution and sales activities of each Fund and the historical and ongoing performance of each Fund.

Each Independent Trustee sits on the Trust's Audit Committee, which has the responsibility, among other things, to: (i) select, oversee and approve the compensation of the Trust's independent registered public accounting firm; (ii) oversee the Trust's accounting and financial reporting policies and practices, its internal controls and, as appropriate, the internal controls of certain service providers; and (iii) oversee the quality and objectivity of the Fund's financial statements and the independent audit(s) thereof. The Audit Committee met three times during the fiscal year ended June 30, 2012.

Each Independent Trustee sits on the Trust's Nominating Committee, which has the responsibility, among other things, to: (i) make recommendations and to consider shareholder recommendations for nominations for Board members; (ii) review Board governance procedures and recommend any appropriate changes to the full Board; (iii) periodically review Trustee compensation and recommend any changes to the Independent Trustees as a group; and (iv) make recommendations to the full Board for nominations for membership on all committees, review all committee assignments annually and periodically review the responsibilities and need for all committees of the Board. The Nominating Committee met three times during the fiscal year ended June 30, 2012.

Ms. Cepeda, Mr. Roob, Mr. Thomas and Mr. Lytle sit on the Trust's Distribution Committee, which has the responsibility, among other things, to: (i) review matters relating to the marketing, distribution and sales activities of the Funds; (ii) oversee the effectiveness of marketing, distribution and sales activities; and (iii) review any proposed distribution strategies and marketing activities relating to the sales of the shares of the Funds. Because the Distribution Committee is new, it did not meet during the fiscal year ended June 30, 2012.

24

Mr. Murphy, Ms. Smith and Mr. Reilly sit on the Trust's Performance Committee, which has the responsibility, among other things, to: (i) review quarterly reports on the investment performance of each Fund; (ii) review and consider proposed changes to investment objectives and strategies and the use of new financial instruments for each Fund; and (iii) review the kind, scope and format of, and the time periods covered by, the investment performance data and related reports. Because the Performance Committee is new, it did not meet during the fiscal year ended June 30, 2012.

The Board also at times creates other committees of Board members to assist in the evaluation of specific matters. The Independent Trustees have also engaged independent legal counsel, and the Trustees have from time to time engaged consultants and other advisors to assist them in performing their oversight responsibilities.

The Board believes that the existing Board structure for the Trust is appropriate because it allows the Independent Trustees to exercise independent judgment in evaluating the governance of the Trust and performance of the Fund's service providers, while also providing the Board with the invaluable insight of an Interested Trustee, who, as an officer of the Advisor, participates in the day-to-day management of the Trust's affairs, including risk management.

Board oversight of risk management

The Board, as a whole, considers risk management issues as part of its general oversight responsibilities throughout the year at regular board meetings, through regular reports that have been developed by Fund management and the Advisor. These reports address certain investment, valuation and compliance matters. The Board also may receive special written reports or presentations on a variety of risk issues, either upon the Board's request or upon the initiative of the Advisor, including discussions with the Advisor's Chief Risk Officer. In addition, the Audit Committee of the Board meets at least annually with the Advisor's internal audit group to discuss the results of the internal audit group's examinations of the functions and processes of the Advisor that affect the Fund and to be advised regarding the internal audit group's plans for upcoming audits.

With respect to investment risk, the Board receives regular written reports describing and analyzing the investment performance of the Fund. The Board discusses these reports and the performance of the Fund and investment risks with management of the Advisor at the Board's regular meetings. To the extent that the Advisor seeks to change the Fund's investment strategy that may have a material impact on the Fund's risk profile or invest in a new type of security or instrument, the Board generally is provided information on such proposed changes for the Board's approval. In addition, the Advisor provides, at the request of the Board, an annual report on the use of derivatives by the Fund.

With respect to valuation, the Advisor provides regular written reports to the Board that enables the Board to monitor fair valued securities in the Fund. Such reports also include information concerning illiquid securities held by the Fund. In addition, the Audit Committee reviews valuation procedures and pricing results with the Trust's independent registered public accounting firm in connection with such Committee's review of the results of the audit of the Fund's year end financial statements.

With respect to compliance risks, the Board receives regular compliance reports prepared by the Advisor's compliance group and meets regularly with the Trust's Chief Compliance Officer ("CCO") to discuss compliance issues, including compliance risks. As required under SEC rules, the Independent Trustees meet at least quarterly in executive session with the CCO, and the Trust's CCO prepares and presents an annual written compliance report to the Board. The Board adopts compliance policies and procedures for the Trust

25

and receives information about the procedures in place for the Trust's service providers. The compliance policies and procedures are specifically designed to detect and prevent violations of the federal securities laws.

At the request of the Board, the Advisor also has provided presentations to the Board with respect to the Advisor's operational risk management.

Trustee qualifications

When a vacancy occurs on the Board, the Nominating Committee of the Board evaluates a candidate's qualification for Board membership and the independence of such candidate from the Advisor and other principal service providers. The Nominating Committee will consider nominees recommended by Qualifying Fund Shareholders if an Independent Trustee vacancy on the Board occurs. A Qualifying Fund Shareholder is a shareholder that: (i) owns of record, or beneficially through a financial intermediary, 1/2 of 1% or more of the Trust's outstanding shares and (ii) has been a shareholder of at least 1/2 of 1% of the Trust's total outstanding shares for 12 months or more prior to submitting the recommendation to the Nominating Committee. In order to recommend a nominee, a Qualifying Fund Shareholder should send a letter to the chairperson of the Nominating Committee, Adela Cepeda, care of Mark Kemper, the Secretary of the Trust, at UBS Global Asset Management, One North Wacker Drive, Chicago, Illinois 60606, and indicate on the envelope "Nominating Committee." The Qualifying Fund Shareholder's letter should include: (i) the name and address of the Qualifying Fund Shareholder making the recommendation; (ii) the number of shares of each class and series of shares of the Trust which are owned of record and beneficially by such Qualifying Fund Shareholder and the length of time that such shares have been so owned by the Qualifying Fund Shareholder; (iii) a description of all arrangements and understandings between such Qualifying Fund Shareholder and any other person or persons (naming such person or persons) pursuant to which the recommendation is being made; (iv) the name and address of the nominee; and (v) the nominee's resume or curriculum vitae. The Qualifying Fund Shareholder's letter must be accompanied by a written consent of the individual to stand for election if nominated for the Board and to serve if elected by shareholders.

The Nominating Committee of the Board believes that it is in the best interests of the Trust and its shareholders to obtain highly-qualified individuals to serve as members of the Board. In assessing Trustees for the Board, the Nominating Committee may consider factors such as the person's judgment, skill, diversity and experience with investment companies and other organizations of comparable purpose, complexity and size and subject to similar legal restrictions and oversight and the interplay of a Trustee or candidate's experience with the experience of other Board members. The Board believes that collectively, the Trustees currently serving on the Board have balanced and diverse experience, qualifications, attributes and skills that allow the Board to effectively oversee the management of the Trust and protect the interests of shareholders. The Board noted that each Independent Trustee had experience serving as a director on the boards of operating companies and/or other investment companies. The Board also considered that Adela Cepeda, John J. Murphy, Edward M. Roob and J. Mikesell Thomas have or had careers in the financial services or investment industries, including holding executive positions in companies engaged in these industries, which allows these Trustees to bring valuable, relevant experience as members of the Board. The Board also noted that both Frank K. Reilly and Abbie J. Smith, as Professors of Finance and Accounting, respectively, also have the relevant skills and experience to serve as members of the Board. In addition, the Board considered that Shawn Lytle would contribute valuable experience due to his position with the Advisor.

The Advisor is responsible for paying its own expenses. The Fund pays the following expenses: (1) the fees and expenses of the Trust's disinterested Trustees; (2) the salaries and expenses of any of the Trust's officers or employees who are not affiliated with the Advisor; (3) interest expenses; (4) taxes and governmental fees; (5) brokerage commissions and other expenses incurred in acquiring or disposing of portfolio securities; (6) the expenses of registering and qualifying shares for sale with the SEC and with various state securities commissions; (7) auditing and legal costs; (8) insurance premiums; (9) fees and expenses of the Trust's custodian, administrator and transfer agent and any related services; (10) expenses of obtaining quotations of the Fund's portfolio securities and of pricing the Fund's shares; (11) expenses of maintaining the Trust's legal existence and of shareholders' meetings; (12) expenses of preparation and distribution to existing shareholders of reports, proxies and prospectuses; and (13) fees and expenses of membership in industry organizations.

Fund	Class A			Class C			Class Y
UBS U.S. Defensive Equity Fund		1.50	%		2.25	%		1.25	%

The contractual fee waiver and/or expense reimbursement agreement will remain in place through the period ending October 28, 2014. Thereafter, the expense limit for the Fund will be reviewed each year, at which time the continuation of the expense limit will be considered by the Advisor and the Board of Trustees. The contractual fee waiver and/or expense reimbursement agreement also provide that the Advisor is entitled to reimbursement of fees it waived and/or expenses it reimbursed for a period of three years following such fee waivers and expense reimbursements, provided that the reimbursement by the Fund of the Advisor will not cause the total operating expense ratio to exceed the contractual limit as then may be in effect for the Fund.

General expenses of the Trust (such as costs of maintaining corporate existence, certain legal fees, insurance, etc.) will be allocated to the Fund in proportion to its relative net assets. Expenses that relate exclusively to the Fund, such as certain registration fees, brokerage commissions and other portfolio expenses, will be borne directly by the Fund.

¹  One accounts with assets totaling approximately $114 million are based on performance fees.

²  Two accounts with a total of approximately $487 million have an advisory fee based upon the performance of the accounts.

³  Total assets in the accounts total less than $1 million.

*  Mr. McIntosh became a portfolio manager of the Fund on September 21, 2012.

**  Mr. Lammers became a portfolio manager of the Fund on January 28, 2013.

The portfolio management team's management of the Fund and other accounts could result in potential conflicts of interest if the Fund and other accounts have different objectives, benchmarks and fees because the portfolio management team must allocate its time and investment expertise across multiple accounts, including the Fund. A portfolio manager and his or her team manage the Fund and other accounts utilizing a model portfolio approach that groups similar accounts within a model portfolio. The Advisor manages accounts according to the appropriate model portfolio, including where possible, those accounts that have specific investment restrictions. Accordingly, portfolio holdings, position sizes and industry and sector exposures tend to be similar across accounts, which may minimize the potential for conflicts of interest.

If a portfolio manager identifies a limited investment opportunity that may be suitable for more than one account or model portfolio, the Fund may not be able to take full advantage of that opportunity due to an allocation of filled purchase or sale orders across all eligible model portfolios and accounts. To deal with these situations, the Advisor has adopted procedures for allocating portfolio trades across multiple accounts to provide fair treatment to all accounts.

The management of personal accounts by a portfolio manager may also give rise to potential conflicts of interest. The Advisor and the Trust have adopted Codes of Ethics that govern such personal trading but there is no assurance that the Codes will adequately address all such conflicts.

UBS Global AM's compensation and benefits programs are designed to provide its investment professionals with incentives to excel, and to promote an entrepreneurial, performance-oriented culture with clear accountability. They also align the interests of investment professionals with those of our clients.

The total compensation received by the portfolio managers and analysts at UBS Global AM, including the Fund's portfolio managers, has up to three basic components—a fixed component (base salary and benefits), a variable cash component and, over a certain total compensation threshold, a variable deferred component. These are described in more detail below:

•  The fixed component (base salary and benefits) is set with the aim of being competitive in the industry and is monitored and adjusted periodically with reference to the relevant local labor market in order to remain

38

so. The fixed component is used to recognize the experience, skills and knowledge that portfolio managers and analysts bring to their roles.

•  Variable compensation is determined annually on a discretionary basis. It is correlated with the individual's financial and non-financial contribution and with the performance of their respective function, UBS Global AM and UBS as a whole. As its name implies, variable compensation can be variable and is delivered in cash and, over a certain total compensation threshold, deferred.

•  Variable deferred—employees may have a portion of their variable compensation deferred. The main deferral plan is the UBS Global Asset Management Equity Ownership Plan (Global AM EOP) which vests pro rata over a three year period, subject to continued service. Through the Global AM EOP, awards are granted in the form of some combination of vehicles aligned to selected UBS Global AM funds, UBS shares or notional shares. The vehicles aligned to selected UBS Global Asset Management funds are called Alternative Investment Vehicles or AIVs. UBS Global AM believes that not only does this deferral plan reinforce the critical importance of creating long-term business value, it also serves as an effective retention tool.

UBS Global AM strongly believes that aligning portfolio managers' variable compensation to both the short-term and longer-term performance of their portfolios closely aligns the portfolio managers' interests with those of the firm's clients. The total annual variable compensation pool available for distribution generally dependent upon the overall profitability of UBS Group and UBS Global Asset Management.

The allocation of the variable compensation pool to each portfolio manager is linked to the pre-tax investment performance of the Fund versus its benchmark and, where appropriate, peer strategies, over one and three years.

For analysts, variable compensation is, in general, based on the performance of some combination of model and/or client portfolios, generally evaluated over one and three years and coupled with a qualitative assessment of their contribution.

Principal underwriting arrangements

UBS Global AM (US) (the "Underwriter"), with its principal office located at 1285 Avenue of the Americas, New York, NY 10019-6028, acts as the principal underwriter of each class of shares of the Fund pursuant to a Principal Underwriting Contract with the Trust. The Principal Underwriting Contract requires the Underwriter to use its best efforts, consistent with its other businesses, to sell shares of the Fund. Shares of the Fund are offered continuously. The Underwriter enters into dealer agreements with other broker-dealers (affiliated and non-affiliated) and with other financial institutions to authorize them to sell Fund shares.

Under separate plans pertaining to the Class A and Class C shares of the Fund adopted by the Trust in the manner prescribed under Rule 12b-1 under the Act (each, respectively, a "Class A Plan" and "Class C Plan," and collectively, "Plans"), the Fund pays the Underwriter a service fee, accrued daily and payable monthly, at the annual rate of 0.25% of the average daily net assets of each class of shares. Under the Class C Plan, the Fund pays the Underwriter a distribution fee, accrued daily and payable monthly, at the annual rate of 0.75% of the average daily net assets of the class of shares. There is no distribution plan with respect to the Fund's Class Y shares and the Fund pays no service or distribution fees with respect to its Class Y shares.

The Underwriter uses the service fees under the Plans for Class A and Class C shares primarily to pay dealers for shareholder servicing, currently at the annual rate of 0.25% of the aggregate investment amounts

40

maintained in the Fund by each dealer. Each dealer then compensates its investment professionals for shareholder servicing that they perform and offsets its own expenses in servicing and maintaining shareholder accounts including related overhead expenses.

The Underwriter uses the distribution fees under the Class C Plan to offset the commissions it pays to dealers for selling the Fund's Class C shares and to offset the Fund's marketing costs attributable to such Class, such as the preparation, printing and distribution of sales literature, advertising and prospectuses and other shareholder materials to prospective investors. The Underwriter may also use distribution fees to pay additional compensation to dealers and to offset other costs allocated to the Underwriter's distribution activities.

The Underwriter receives the proceeds of the initial sales charge paid when Class A shares are bought and of the contingent deferred sales charge paid upon sales of shares. These proceeds also may be used to cover distribution expenses.

UBS Global AM (US) may also make cash and non-cash payments to banks, broker-dealers, insurance companies, financial planning firms and other financial intermediaries (collectively, "Financial Intermediaries"), that sell shares of the Fund, subject to UBS Global AM (US)'s internal policies and procedures. The source of such payments may come from sales charges on such shares, 12b-1 fees collected from the Fund and/or from the underwriter's own resources (including through transfers from affiliates). Payments made out of the underwriter's own resources are often referred to as "revenue sharing." UBS Global AM (US) provides Financial Intermediaries with sales literature and advertising materials relating to the registered investment companies advised by UBS Global AM (US). UBS Global AM (US) also shares expenses with Financial Intermediaries for costs incurred in hosting seminars for employees and clients of Financial Intermediaries, subject to UBS Global AM (US)'s internal policies and procedures governing payments for such seminars. These seminars may take place at UBS Global AM (US)'s headquarters or other appropriate locations and may include reimbursement of travel expenses (i.e., transportation, lodging and meals) of employees of Financial Intermediaries in connection with training and education seminars. Subject to UBS Global AM (US)'s internal policies and procedures, UBS Global AM (US) may provide any or all of the following to employees of Financial Intermediaries and their guest(s): (i) an occasional meal, a sporting event or theater ticket or other comparable entertainment; (ii) gifts of less than $100 per person per year; and/or (iii) UBS Global AM (US)'s promotional items of nominal value (golf balls, shirts, etc.).

In addition, Financial Intermediaries may maintain omnibus accounts and/or have similar arrangements with UBS Global AM (US) and may be paid by UBS Global AM (US) for providing sub-transfer agency and other services. Financial Intermediaries may be paid a sub-transfer agency or related fee out of Fund assets similar to that which the Fund otherwise would have paid the Fund's transfer agent. In addition, the Financial Intermediary, for the services provided, may charge a higher fee than would be represented by the sub-transfer agency or related fee. To the extent 12b-1 fees and sub-transfer agency or related fees do not meet the charge, the underwriter or an affiliate will pay the difference out of its own resources. Such payments are often referred to as "revenue sharing." Such expenses, to the extent they are Fund expenses, are included in the annual operating expenses set forth in the Fund's prospectus.

You should ask your Financial Intermediary about any payment it receives from the underwriter and any services provided.

The Plans and the Principal Underwriting Contract specify that the Fund must pay service and distribution fees to the Underwriter as compensation for its service and distribution related activities, not as reimbursement for specific expenses incurred. Therefore, even if the Underwriter's expenses for the Fund exceed the service or distribution fees it receives, the Fund will not be obligated to pay more than those fees. On the other hand,

41

if the Underwriter's expenses are less than such fees, it will retain its full fees and realize a profit. Expenses in excess of service and distribution fees received or accrued through the termination date of any Plan will be the Underwriter's sole responsibility and not that of the Fund. Annually, the Board reviews the Plans and the Underwriter's corresponding expenses for each class of shares of the Fund separately from the Plans and expenses of the other classes of shares.

Among other things, each Plan provides that (1) the Underwriter will submit to the Board at least quarterly, and the Board members will review, reports regarding all amounts expended under the Plan and the purposes for which such expenditures were made, (2) the Plan will continue in effect only so long as it is approved at least annually, and any material amendment thereto is approved, by the Board, including those Board members who are not "interested persons" of the Trust and who have no direct or indirect financial interest in the operation of the Plan or any agreement related to the Plan, acting in person at a meeting called for that purpose, (3) payments by the Fund under the Plan shall not be materially increased without the approval by a majority of the outstanding voting securities of the relevant class of the Fund, and (4) while the Plan remains in effect, the selection and nomination of Board members who are not "interested persons" of the Trust shall be committed to the discretion of the Board members who are not "interested persons" of the Trust.

In reporting amounts expended under the Plans to the Board members, the Underwriter allocates expenses attributable to the sale of each class of the Fund's shares to such class based on the ratio of sales of shares of such class to the sales of both classes of shares. The fees paid by one class of the Fund's shares will not be used to subsidize the sale of any other class of the Fund's shares.

The Fund paid (or accrued) the following service and/or distribution fees to UBS Global AM (US) under the Class A and Class C Plans during the fiscal year ended June 30, 2012:

Fund	Class A		Class C
UBS U.S. Defensive Equity Fund	$	30,133	$	38,261

Amounts spent on behalf of the Fund's Class A shares pursuant to the Class A Plan during the fiscal year ended June 30, 2012 are set forth below:

Marketing and advertising	$	227,497
Payments to broker-dealers		98
Printing of prospectuses and SAIs		58

Payments to broker-dealers		11,009

In approving the Class A Plan and the Class C Plan, the Board considered all of the features of the distribution system and the anticipated benefits to the Fund and its shareholders. With regard to each Plan, the Board considered (1) the advantages to the shareholders of economies of scale resulting from growth in the Fund's assets and potential continued growth, (2) the services provided to the Fund and its shareholders by the Underwriter, (3) the services provided by dealers pursuant to dealer agreements with the Underwriter, and (4) the Underwriter shareholder service-related and, where applicable, distribution-related expenses and costs.

With respect to each Plan, the Board considered all compensation that the Underwriter would receive under the Plan and the Principal Underwriting Contract, including service fees and, as applicable, initial sales charges, distribution fees and contingent deferred sales charges. The Board also considered the benefits that would accrue to the Underwriter under each Plan, in that the Underwriter would receive service, distribution, advisory and administrative fees that are calculated based upon a percentage of the average net assets of the Fund, which fees would increase if the Plans were successful and the Fund attained and maintained significant asset levels.

Under the Principal Underwriting Contract, UBS Global AM (US) earned the following approximate amounts of sales charges in connection with the sale of shares, and retained the following approximate amounts, net of concessions to dealers:

	Fiscal year ended June 30,

Personal trading policies

The Trust, the Advisor and the Underwriter have adopted a Code of Ethics. The Code of Ethics establishes standards by which employees of UBS Global Asset Management (including all employees of the Advisor and Underwriter) (together, "Covered Persons") must abide when engaging in personal securities trading conduct.

Under the Code of Ethics, Covered Persons are prohibited from, among other things: (i) executing a securities transaction on a day during which the Fund has a pending or executed buy or sell in the same security; (ii) entering into a net short position with respect to any security; (iii) purchasing or selling futures (except currency forwards) that are not traded on an exchange, as well as options on any type of futures (exchange traded or not); (iv) purchasing securities issued by a supplier or vendor about which the Covered Person has information or with whom the Covered Person is directly involved in negotiating a contract; and (v) acquiring securities in an initial public offering (other than a new offering of a registered open-end investment company).

In addition, Covered Persons must obtain prior written approval before purchasing, selling or transferring any security subject to certain exceptions listed in the Code of Ethics. Covered Persons and Trustees are required to file the following reports: (1) an initial holdings report disclosing all securities owned by the Covered Person or Interested Trustee and any securities accounts maintained by the Covered Person or Interested Trustee, which must be filed within ten days of becoming a Covered Person or Interested Trustee (Independent Trustees are not required to file this report); (2) quarterly reports of security investment transactions and new securities accounts. Independent Trustees need only report a transaction in a security if such Trustee, at the time of the transaction, knew or should have known, in the ordinary course of fulfilling his official duties as a Trustee, that, during the 15-day period immediately preceding or after the date of the transaction by the Trustee, such security was purchased or sold by the Fund, or was being considered for purchase or sale by the Fund; and (3) an annual certification that they have read and understand the Code of Ethics, that they have complied with its requirements during the preceding year, and that they have disclosed or reported all personal transactions/holdings required to be disclosed or reported.

A copy of the Code of Ethics has been filed with and is available through the SEC.

Proxy voting policies

The Board of Trustees believes that the voting of proxies on securities held by the Fund is an important element of the overall investment process. As such, the Board has delegated the responsibility to vote such proxies to UBS Global AM (Americas). Following is a summary of UBS Global AM (Americas)'s proxy voting policy.

You may obtain information about the Fund's proxy voting decisions, without charge, online on the Trust's Web Site (www.ubs.com/ubsglobalam-proxy) or the EDGAR database on the SEC's Web Site (www.sec.gov).

The proxy voting policy of UBS Global AM (Americas) is based on its belief that voting rights have economic value and should be treated accordingly. Generally, UBS Global AM (Americas) expects the boards of directors of companies issuing securities held by its clients to act in the service of the shareholders, view themselves as stewards of the company, exercise good judgment and practice diligent oversight of the management of the company. While there is no absolute set of rules that determine appropriate corporate governance under all circumstances and no set of rules will guarantee ethical behavior, there are certain principles, which provide

44

evidence of good corporate governance. UBS Global AM (Americas) may delegate to an independent proxy voting and research service the authority to exercise the voting rights associated with certain client holdings. Any such delegation shall be made with the direction that the votes be exercised in accordance with UBS Global AM (Americas)'s proxy voting policy.

When UBS Global AM (Americas)'s view of a company's management is favorable, UBS Global AM (Americas) generally supports current management initiatives. When UBS Global AM (Americas)'s view is that changes to the management structure would probably increase shareholder value, UBS Global AM (Americas) may not support existing management proposals. In general, UBS Global AM (Americas) generally exercises voting rights in accordance with the following principles: (1) with respect to board structure, (a) the roles of chairman and chief executive generally should be separated, (b) board members should have appropriate and diverse experience and be capable of providing good judgment and diligent oversight of management of the company, and (c) the board should include executive and non-executive members and the non-executive members should provide a challenging, but generally supportive environment; and (2) with respect to board responsibilities, (a) the whole board should be fully involved in endorsing strategy and in all major strategic decisions, and (b) the board should ensure that, among other things, at all times the interests of executives and shareholders are aligned and the financial audit is independent and accurate. In addition, UBS Global AM (Americas) focuses on the following areas of concern when voting its clients' securities: economic value resulting from acquisitions or disposals; operational performance; quality of management; independent board members not holding management accountable; quality of internal controls; lack of transparency; inadequate succession planning; poor approach to social responsibility; inefficient management structure; and corporate activity designed to frustrate the ability of shareholders to hold the board accountable or realize the maximum value of their investment. UBS Global AM (Americas) exercises its voting rights in accordance with overarching rationales outlined by its proxy voting policies and procedures that are based on the principles described above.

UBS Global AM (Americas) has implemented procedures designed to identify whether it has a conflict of interest in voting a particular proxy proposal, which may arise as a result of its or its affiliates' client relationships, marketing efforts or banking, investment banking and broker-dealer activities. To address such conflicts, UBS Global AM (Americas) has imposed information barriers between it and its affiliates who conduct banking, investment banking and broker-dealer activities and has implemented procedures to prevent business, sales and marketing issues from influencing its proxy votes. Whenever UBS Global AM (Americas) is aware of a conflict with respect to a particular proxy, the UBS Global AM Corporate Governance Committee is required to review and resolve the manner in which such proxy is voted.

Portfolio holdings disclosure policies and procedures

Introduction. UBS Global AM (Americas) and the Trust's Board of Trustees have adopted portfolio holdings disclosure policies and procedures to govern the disclosure of the portfolio holdings of the Fund (the "Disclosure Policy"). The Trust's policy with respect to the release of portfolio holdings information is to only release such information consistent with applicable legal requirements and the fiduciary duties owed to shareholders. Subject to the limited exceptions described below, the Fund's portfolio holdings will not be made available to anyone outside of UBS Global AM (Americas) unless and until the information has been made available to all shareholders or the general public in a manner consistent with the spirit and terms of the Disclosure Policy. A description of the type and frequency of portfolio holdings that are disclosed to the public is contained in the Fund's Prospectus, as it may be updated from time to time.

The Disclosure Policy requires that the UBS Global AM (Americas) Legal and Compliance Departments address any material conflicts of interest regarding a disclosure of portfolio holdings and determine whether a disclosure of the Fund's portfolio holdings is for a legitimate business purpose and in the best interest of the Fund's shareholders prior to the Treasurer, Assistant Treasurer, Secretary or Assistant Secretary of the Trust or

45

an attorney in the UBS Global AM (Americas) Legal and Compliance Departments authorizing the disclosure of portfolio holdings. The UBS Global AM (Americas) Legal and Compliance Departments will periodically review how the Fund's portfolio holdings are being disclosed to and used by, if at all, shareholders service providers, UBS Global AM (Americas) affiliates, fiduciaries, and broker-dealers, to ensure that such disclosure and use is for legitimate Fund business reasons and consistent with the best interests of the Fund's shareholders.

The Trust's Board of Trustees exercises continuing oversight of the disclosure of Fund portfolio holdings by: (i) overseeing the implementation and enforcement by the Chief Compliance Officer of the Trust of the Disclosure Policy, the Trust's code of ethics and policies and procedures regarding the misuse of inside information; (ii) considering reports and recommendations by the Chief Compliance Officer concerning any material compliance matters (as defined in Rule 38a-1 under the Act and Rule 206(4)-7 under the Investment Advisers Act of 1940 ("Advisers Act")) that may arise in connection with any policies governing portfolio holdings; and (iii) considering whether to approve or ratify any amendment to any policies governing portfolio holdings. The Disclosure Policy may be amended from time to time, subject to approval by the Board of Trustees.

Disclosure of complete portfolio holdings to service providers subject to confidentiality and trading restrictions. UBS Global AM (Americas), for legitimate fund business purposes, may disclose the Fund's complete portfolio holdings if it deems such disclosure necessary and appropriate to rating and ranking organizations, financial printers, proxy voting service providers, pricing information vendors, derivatives collateral managers, third-parties that deliver analytical, statistical or consulting services, custodians or a redeeming party's custodian or transfer agent, as necessary in connection with redemptions in-kind, and other third parties that provide services (collectively, "Service Providers") to UBS Global AM (Americas) and/or the Fund.

Disclosure of complete portfolio holdings to a Service Provider is conditioned on the Service Provider being subject to a written duty of confidentiality, including a duty not to trade on the basis of any material non-public information, pursuant to the terms of the service agreement between the Service Provider and the Trust or UBS Global AM (Americas), or the terms of a separate confidentiality agreement. The frequency with which complete portfolio holdings may be disclosed to a Service Provider, and the length of lag, if any, between the date of information and the date on which the information is disclosed to the Service Provider, is to be determined based on the facts and circumstances, including, without limitation, the nature of the portfolio holdings information to be disclosed, the risk of harm to the Fund's shareholders, and the legitimate fund business purposes served by such disclosure. Disclosure of Fund complete portfolio holdings to a Service Provider must be authorized in writing by the Treasurer, Assistant Treasurer, Secretary or Assistant Secretary of the Trust or by an attorney in the UBS Global AM (Americas) Legal and Compliance Departments.

Disclosure of complete portfolio holdings to UBS Global Asset Management affiliates and certain fiduciaries subject to confidentiality and trading restrictions. The Fund's complete portfolio holdings may be disclosed between and among the following persons (collectively, "Affiliates and Fiduciaries") subject to authorization by the Treasurer, Assistant Treasurer, Secretary or Assistant Secretary of the Trust, or an attorney in the UBS Global AM (Americas) Legal and Compliance Departments, for legitimate fund business purposes within the scope of their official duties and responsibilities, and subject to such Affiliate/Fiduciary's continuing duty of confidentiality and duty not to trade on the basis of any material non-public information, as such duties are imposed under the Trust's and/or UBS Global AM (Americas)'s Code of Ethics, the Fund's policies and procedures regarding the prevention of the misuse of inside information, by agreement or under applicable laws, rules and regulations: (i) persons who are subject to UBS Global AM (Americas)'s Codes of Ethics or the policies and procedures regarding the prevention of the misuse of inside information; (ii) an

46

investment advisor, distributor, administrator, sub-administrator, transfer agent, custodian or securities lending agent to the Fund; (iii) an accounting firm, an auditing firm or outside legal counsel retained by UBS Global AM (Americas) or the Fund; (iv) an investment advisor to whom complete portfolio holdings are disclosed for due diligence purposes when the advisor is in merger or acquisition talks with the Fund's current advisor; and (v) a newly hired investment advisor or sub-advisor to whom complete portfolio holdings are disclosed prior to the time it commences its duties.

The frequency with which complete portfolio holdings may be disclosed between and among Affiliates and Fiduciaries, and the length of the lag, if any, between the date of the information and the date on which the information is disclosed between and among the Affiliates and Fiduciaries, is to be determined by the UBS Global AM (Americas) Legal and Compliance Departments based on the facts and circumstances, including, without limitation, the nature of the portfolio holdings information to be disclosed, and the risk of harm to the Fund and its shareholders, and the legitimate fund business purposes served by such disclosure.

Arrangements to disclose portfolio holdings to service providers and fiduciaries. As of the date of this SAI, the specific Service Providers and Fiduciaries with whom the Trust has arrangements to provide portfolio holdings in advance of their release to the general public in the course of performing or to enable them to perform services for the Fund are:

•  JPMorgan Chase Bank, the Funds' custodian, accounting agent and securities lending agent, receives portfolio holdings information daily on a real-time basis in connection with the custodian, fund accounting, valuation and derivatives collateral management services it provides to the Funds.

•  Ernst & Young LLP, the Fund's independent registered public accounting firm, receives portfolio holdings information on an annual and semiannual basis for financial reporting purposes. There is a 25-day lag between the date of portfolio holdings information and the date on which the information is disclosed to Ernst & Young. Ernst & Young also receives portfolio holdings information annually at year-end for audit purposes. In this case, there is no lag between the date of the portfolio holdings information and the date on which the information is disclosed to Ernst & Young. In addition, Ernst & Young receives holdings twice a year for fiscal income and excise tax provision reporting purposes with a 2-day lag time.

•  GainsKeeper, a third party service provider sub-contracted by JP Morgan Chase Bank to provide tax calculation services in conjunction with fiscal income and excise tax provision reporting purposes, receives portfolio holdings information on a monthly basis with a 3-day lag time after the close of the month.

•  The Fund uses a limited number of financial printers to print and file its annual and semiannual shareholder reports and other regulatory materials. There is at least a three week lag between the date of the portfolio holdings information and the date on which the information is disclosed to the printer.

•  The rating agencies of Morningstar, and Lipper and the financial news and data company, Bloomberg L.P., receive portfolio holdings information on a quarterly basis so that the Fund may be included in each company's industry reports and other materials. There is a 60-day lag between the date of the portfolio holdings information and the date on which the information is disclosed to these companies.

•  Credit Suisse, a prime broker for the Fund, receives portfolio holdings information on a monthly basis in connection with portfolio analysis. There is a 15-day lag between the date of the portfolio holdings information and the date on which the information is disclosed to Credit Suisse.

47

Disclosure of portfolio holdings to broker-dealers in the normal course of managing Fund assets. An investment advisor, administrator or custodian for the Fund may, for legitimate fund business purposes within the scope of their official duties and responsibilities, disclose portfolio holdings (whether partial portfolio holdings or complete portfolio holdings) and other investment positions comprising the Fund to one or more broker-dealers during the course of, or in connection with, normal day-to-day securities and derivatives transactions with or through such broker-dealers subject to the broker-dealer's legal obligation not to use or disclose material non-public information concerning the Fund's portfolio holdings, other investment positions, securities transactions or derivatives transactions without the consent of the Trust or the Treasurer, Assistant Treasurer, Secretary or Assistant Secretary of the Trust or an attorney in the UBS Global AM (Americas) Legal and Compliance Departments. The Trust has not given its consent to any such use or disclosure and no person including the Treasurer, Assistant Treasurer, Secretary or Assistant Secretary of the Trust or an attorney in the UBS Global AM (Americas) Legal and Compliance Departments of UBS Global AM (Americas) is authorized to give such consent except as approved by the Trust's Board of Trustees. In the event consent is given to disclose portfolio holdings to a broker-dealer, the frequency with which the portfolio holdings may be disclosed to a broker-dealer, and the length of the lag, if any, between the date of the information and the date on which the information is disclosed to the broker-dealer, is to be determined based on the facts and circumstances, including, without limitation, the nature of the portfolio holdings information to be disclosed, and the risk of harm to the Fund and its shareholders, and the legitimate fund business purposes served by such disclosure.

Disclosure of non-material information. Policies and procedures regarding disclosure of non-material information permit the officers of the Trust, UBS Global Asset Management Funds portfolio managers and senior officers of UBS Global AM (Americas) Finance, UBS Global AM (Americas) Legal and Compliance Departments, and anyone employed by or associated with UBS Global AM (Americas) who has been authorized by the UBS Global AM (Americas) Legal Department (collectively, "Approved Representatives") to disclose any views, opinions, judgments, advice or commentary, or any analytical, statistical, performance or other information, in connection with or relating to the Fund or its portfolio holdings and/or other investment positions (collectively, commentary and analysis) or any changes in the portfolio holdings of the Fund that occurred after the most recent calendar-quarter end (recent portfolio changes) to any person if such information does not constitute material non-public information.

An Approved Representative must make a good faith determination whether the information constitutes material non-public information, which involves an assessment of the particular facts and circumstances. UBS Global AM (Americas) believes that in most cases recent portfolio changes that involve a few or even several securities in a diversified portfolio or commentary and analysis would be immaterial and would not convey any advantage to a recipient in making an investment decision concerning the Fund. Nonexclusive examples of commentary and analysis include: (i) the allocation of the Fund's portfolio holdings and other investment positions among various asset classes, sectors, industries and countries; (ii) the characteristics of the stock and bond components of the Fund's portfolio holdings and other investment positions; (iii) the attribution of Fund returns by asset class, sector, industry and country; and (iv) the volatility characteristics of the Fund. An Approved Representative may in his or her sole discretion determine whether to deny any request for information made by any person, and may do so for any reason or no reason.

Disclosure of portfolio holdings as required by applicable law. Fund portfolio holdings and other investment positions comprising the Fund may be disclosed to any person as required by applicable laws, rules and regulations. Examples of such required disclosure include, but are not limited to, disclosure of Fund portfolio holdings: (i) in a filing or submission with the SEC or another regulatory body; (ii) in connection with seeking recovery on defaulted bonds in a federal bankruptcy case; (iii) in connection with a lawsuit; or (iv) as required by court order, subpoena or similar process (e.g., arbitration proceedings).

48

Prohibitions on disclosure of portfolio holdings. No person is authorized to disclose Fund portfolio holdings or other investment positions (whether online at www.ubs.com, in writing, by fax, by e-mail, orally or by other means) except in accordance with the Disclosure Policy. In addition, no person is authorized to make disclosure pursuant to the Disclosure Policy if such disclosure would be unlawful under the antifraud provisions of the federal securities laws (as defined in Rule 38a-1 under the Act). Furthermore, UBS Global AM (Americas), in its sole discretion, may determine not to disclose portfolio holdings or other investment positions comprising the Fund to any person who might otherwise be eligible to receive such information under the Disclosure Policy, or may determine to make such disclosures publicly as described above.

Prohibitions on receipt of compensation or other consideration. Neither UBS Global AM (Americas), the Fund nor any other person may pay or receive any compensation or other consideration of any type for the purpose of obtaining disclosure of Fund portfolio holdings or other investment positions. "Consideration" includes any agreement to maintain assets in the Fund or in other investment companies or accounts managed by the investment advisor or by any affiliated person of the investment advisor.

Bank line of credit

The Fund participates with other funds managed by UBS Global AM (Americas) in a $50 million committed credit facility (the "Credit Facility") with JPMorgan Chase Bank, to be utilized for temporary financing until the settlement of sales or purchases of portfolio securities, the repurchase or redemption of shares at the request of shareholders and other temporary or emergency purposes. Under the Credit Facility arrangement, the Fund has agreed to pay a commitment fee, pro rata, based on the relative asset size of the funds participating in the credit facility. Interest is charged to the Fund at rates based on prevailing market rates at the time of borrowings.

Portfolio transactions and brokerage commissions

The Advisor is responsible for decisions to buy and sell securities for the Fund and for the placement of the Fund's portfolio business and the negotiation of commissions, if any, paid on such transactions. Fixed income securities in which the Fund invests are traded in the over-the-counter market. These securities are generally traded on a net basis with dealers acting as principal for their own accounts without a stated commission, although the bid/ask spread quoted on securities includes an implicit profit to the dealers. In over-the-counter transactions, orders are placed directly with a principal market-maker unless a better price and execution can be obtained by using a broker. Brokerage commissions are paid on transactions in listed securities, futures contracts and options. The Advisor is responsible for effecting portfolio transactions and will do so in a manner deemed fair and reasonable to the Fund. Under its advisory agreement with the Fund, the Advisor is authorized to utilize the trading desk of its foreign affiliates to execute foreign securities transactions, but monitors the selection by such affiliates of brokers and dealers used to execute transactions for the Fund.

The primary consideration in all portfolio transactions will be prompt execution of orders in an efficient manner at the most favorable price. However, subject to policies established by the Board of the Trust, the Fund may pay a broker-dealer a commission for effecting a portfolio transaction for the Fund in excess of the amount of commission another broker-dealer would have charged if the Advisor determines in good faith that the commission paid was reasonable in relation to the brokerage or research services provided by such broker-dealer, viewed in terms of that particular transaction or such firm's overall responsibilities with respect to the clients, including the Fund, as to which the Advisor exercises investment discretion. In selecting and monitoring broker-dealers and negotiating commissions, the Advisor considers the firm's reliability, the quality of its execution services on a continuing basis and its financial condition. When more than one firm is believed to meet these criteria, preference may be given to brokers who provide research or statistical material or other services to the Fund or the Advisor. Such services include advice, both directly and in writing, as to the value of the securities; the advisability of

49

investing in, purchasing or selling securities; and the availability of securities, or purchasers or sellers of securities, as well as analyses and reports concerning issues, industries, securities, economic factors and trends, portfolio strategy and the performance of accounts. This allows the Advisor to supplement its own investment research activities and obtain the views and information of others prior to making investment decisions. The Advisor is of the opinion that, because this material must be analyzed and reviewed by its staff, the receipt and use of such material does not tend to reduce expenses but may benefit the Fund by supplementing the Advisor's research.

The Advisor effects portfolio transactions for other investment companies and advisory accounts. Research services furnished by dealers through whom the Fund effects its securities transactions may be used by the Advisor, or its affiliated investment advisors, in servicing all of their accounts; not all such services may be used in connection with the Fund. In the opinion of the Advisor, it is not possible to measure separately the benefits from research services to each of the accounts (including the Fund). The Advisor will attempt to equitably allocate portfolio transactions among the Fund and others whenever concurrent decisions are made to purchase or sell securities by the Fund and another. In making such allocations between the Fund and others, the main factors to be considered are the respective investment objectives, the relative size of portfolio holdings of the same or comparable securities, the availability of cash for investment, the size of investment commitments generally held and the opinions of the persons responsible for recommending investments to the Fund and the others. In some cases, this procedure could have an adverse effect on the Fund. In the opinion of the Advisor, however, the results of such procedures will, on the whole, be in the best interest of each of the clients.

When buying or selling securities, the Fund may pay commissions to brokers who are affiliated with the Advisor or the Fund. The Fund may purchase securities in certain underwritten offerings for which an affiliate of the Fund or the Advisor may act as an underwriter. The Fund may effect futures transactions through, and pay commissions to, FCMs who are affiliated with the Advisor or the Fund in accordance with procedures adopted by the Board.

The Fund incurred brokerage commissions as follows:

	Fiscal year ended June 30,
Fund	2012		2011		2010
UBS U.S. Defensive Equity Fund	$	44,4851	$	81,177	$	306,113

¹  The decrease in brokerage commissions paid for the fiscal year ended June 30, 2012 was due to a decrease in Fund assets.

During the fiscal year ended June 30, 2012, the Fund's commissions for securities transactions to brokers which provided research services to the Fund were as follows:

Fund	Value of Securities Transactions		Brokerage Commissions
UBS U.S. Defensive Equity Fund	$	69,369,089	$	41,032

For the fiscal year ended June 30, 2012, the Fund paid brokerage commissions to UBS Securities, LLC, an affiliate of the Advisor and Underwriter, as follows:

Fund	Aggregate dollar amount of commissions paid to UBS Securities, LLC		% of aggregate commissions paid to UBS Securities, LLC			% of aggregate dollar amount paid to UBS Securities, LLC
UBS U.S. Defensive Equity Fund	$	165		0.37	%		0.05	%

50

For the fiscal year ended June 30, 2011, the Fund paid brokerage commissions to UBS Securities, LLC, an affiliate of the Advisor and Underwriter, as follows:

Fund	Aggregate dollar amount of commissions paid to UBS AG		% of aggregate commissions paid to UBS AG			% of aggregate dollar amount paid to UBS AG
UBS U.S. Defensive Equity Fund	$	237		0.29	%		0.05	%

For the fiscal year ended June 30, 2010, the Fund paid brokerage commissions to UBS AG, an affiliate of the Advisor and Underwriter, as follows:

Fund	Aggregate dollar amount of commissions paid to UBS AG		% of aggregate commissions paid to UBS AG			% of aggregate dollar amount paid to UBS AG
UBS U.S. Defensive Equity Fund	$	781		0.26	%		0.03	%

As of June 30, 2012, the Fund owned securities issued by the following companies which are regular broker-dealers for the Fund:

UBS U.S. Defensive Equity Fund

Issuer	Value
Citigroup, Inc.	$	373,297
Goldman Sachs Group, Inc.		124,618
JPMorgan Chase & Co.		385,884
Morgan Stanley		230,522

The Fund maintains a commission recapture program with certain brokers for the Fund. Under the program, a percentage of commissions generated by portfolio transactions for the Fund is rebated to the Fund by the brokers.

Portfolio turnover

The Fund is free to dispose of its portfolio securities at any time, subject to complying with the Code and the Act, when changes in circumstances or conditions make such a move desirable in light of the Fund's investment objective. The Fund will not attempt to achieve or be limited to a predetermined rate of portfolio turnover, such a turnover always being incidental to transactions undertaken with a view to achieving the Fund's investment objective.

The Fund does not intend to use short-term trading as a primary means of achieving its investment objective. The rate of portfolio turnover shall be calculated by dividing (a) the lesser of purchases and sales of portfolio securities for the particular fiscal year by (b) the monthly average of the value of the portfolio securities owned by the Fund during the particular fiscal year. Such monthly average shall be calculated by totaling the values of the portfolio securities as of the beginning and end of the first month of the particular fiscal year and as of the end of each of the succeeding eleven months and dividing the sum by 13.

The portfolio turnover rate for the Fund may exceed 100%. High portfolio turnover rates (over 100%) may involve correspondingly greater brokerage commissions and other transaction costs, which will be borne directly by the Fund and ultimately by the Fund's shareholders. In addition, high portfolio turnover may result in increased short-term capital gains, which, when distributed to shareholders, are treated as ordinary income.

51

The portfolio turnover rate of the Fund for the fiscal years ended June 30, 2012, 2011 and 2010 was as follows:

	Fiscal year ended June 30,
Fund	2012			2011			2010
UBS U.S. Defensive Equity Fund		85	%		85	%		130	%

Shares of beneficial interest

The Trust currently offers three classes of shares for the Fund: the UBS Fund—Class A (the Class A shares), UBS Fund—Class C (the Class C shares) and UBS Fund—Class Y (the Class Y shares).

The Fund is authorized to issue an unlimited number of shares of beneficial interest with a $0.001 par value per share. Each share of beneficial interest represents an equal proportionate interest in the assets and liabilities of the Fund and has identical voting, dividend, redemption, liquidation and other rights and preferences as the other classes of the Fund, except that only the Class A shares may vote on any matter affecting the Class A Plan. Similarly, only Class C shares may vote on matters that affect only the Class C Plan. No class may vote on matters that affect only another class. Under Delaware law, the Trust does not normally hold annual meetings of shareholders. Shareholders' meetings may be held from time to time to consider certain matters, including changes to the Fund's fundamental investment objective and fundamental investment policies, changes to the Trust's investment advisory agreements and the election of Trustees when required by the Act. When matters are submitted to shareholders for a vote, shareholders are entitled to one vote per share with proportionate voting for fractional shares. The shares of the Fund do not have cumulative voting rights or any preemptive or conversion rights, and the Trustees have authority, from time to time, to divide or combine the shares of the Fund into a greater or lesser number of shares so affected. In the case of a liquidation of the Fund, each shareholder of the Fund will be entitled to share, based upon the shareholder's percentage share ownership, in the distribution of assets, net of liabilities, of the Fund. No shareholder is liable for further calls or assessment by the Fund.

On any matters affecting only one series of the Trust or class, only the shareholders of that series or class are entitled to vote. On matters relating to the Trust but affecting the series of the Trust differently, separate votes by the affected series or classes are required. With respect to the submission to shareholder vote of a matter requiring separate voting by a series or class, the matter shall have been effectively acted upon with respect to any series or class if a majority of the outstanding voting securities of that series or class votes for the approval of the matter, notwithstanding that: (1) the matter has not been approved by a majority of the outstanding voting securities of any other series or class; and (2) the matter has not been approved by a majority of the outstanding voting securities of the Trust.

The Trustees of the Trust do not intend to hold annual meetings of shareholders of the Fund. The SEC, however, requires the Trustees to promptly call a meeting for the purpose of voting upon the question of removal of any Trustee when requested to do so by not less than 10% of the outstanding shareholders of the Fund. In addition, subject to certain conditions, shareholders of the Fund may apply to the Fund to communicate with other shareholders to request a shareholders' meeting to vote upon the removal of a Trustee or Trustees.

Reduced sales charges, additional purchase, exchange and redemption information and other services

Sales charge reductions and waivers

Waivers of sales charges—Class A shares. The following additional sales charge waivers are available for Class A shares if you:

•  Acquire shares in connection with a reorganization pursuant to which the Fund acquires substantially all of the assets and liabilities of another fund in exchange solely for shares of the acquiring fund;

•  Acquire shares in connection with the disposition of proceeds from the sale of shares of Managed High Yield Plus Fund Inc. that were acquired during that fund's initial public offering of shares and that meet certain other conditions described in its prospectus; or

•  Acquire shares in connection with shares purchased by UBS Global AM (US) or any affiliate on behalf of a discretionary advisory client.

Reinstatement privilege—Class A shares. Shareholders who have redeemed Class A shares may reinstate their account without a sales charge by notifying the transfer agent of such desire and forwarding a check for the amount to be purchased within 365 days after the date of redemption. The reinstatement will be made at the net asset value per share next computed after the notice of reinstatement and check are received. The amount of a purchase under this reinstatement privilege cannot exceed the amount of the redemption proceeds. Gain on a redemption will be taxable regardless of whether the reinstatement privilege is exercised, although a loss arising out of a redemption will not be deductible to the extent the reinstatement privilege is exercised within 30 days after redemption, in which event an adjustment will be made to the shareholder's tax basis for shares acquired pursuant to the reinstatement privilege. Gain or loss on a redemption also will be readjusted for federal income tax purposes by the amount of any sales charge paid on Class A shares, under the circumstances and to the extent described in "Taxes—Special Rule for Class A Shareholders," below.

Purchases of shares through the PACE^SM Multi Advisor Program. An investor who participates in the PACE^SM Multi Advisor Program is eligible to purchase Class A shares. The PACE^SM Multi Advisor Program is an advisory program sponsored by UBS Financial Services Inc. that provides comprehensive investment services, including investor profiling, a personalized asset allocation strategy using an appropriate combination of funds and a quarterly investment performance review. Participation in the PACE^SM Multi Advisor Program is subject to payment of an advisory fee at the effective maximum annual rate of 1.5% of assets. Employees of UBS Financial Services Inc. and its affiliates are entitled to a waiver of this fee. Please contact your UBS Financial Services Inc. Financial Advisor or UBS Financial Services Inc. correspondent firms for more information concerning mutual funds that are available through the PACE^SM Multi Advisor Program. Shareholders who owned Class Y shares of the Fund through the PACE Multi-Advisor Program as of November 15, 2001, will be eligible to continue to purchase Class Y shares of the Fund through the program.

Class Y shares are sold without sales charges and do not pay ongoing 12b-1 distribution or service fees. Prior to June 16, 2010, UBS Global AM (US), the principal underwriter of the Fund, made payments out of its own resources to certain affiliated dealers (e.g., UBS Financial Services Inc.) and, from time to time, unaffiliated dealers. These dealers may continue to receive such payments after June 16, 2010, in UBS Global AM (US)'s sole discretion. Only specific types of investors can purchase Class Y shares.

53

Additional compensation to affiliated dealer. UBS Global AM (US) pays its affiliate, UBS Financial Services Inc., the following additional compensation in connection with the sale of Fund shares:

•  0.05% of the value (at the time of sale) of all shares of the Fund sold through UBS Financial Services Inc.; and

•  a monthly retention fee at the annual rate of 0.10% of the value of shares of the Fund that are held in a UBS Financial Services Inc. account at month-end.

The foregoing payments are made by UBS Global AM (US) out of its own resources. Such payments are often referred to as "revenue sharing."

Additional compensation to financial institution(s). The unaffiliated financial institutions that receive additional compensation (as described in the prospectus) from UBS Global AM (US) or the Advisor, from the Advisor's own resources, include:

Morgan Stanley Smith Barney LLC., Citigroup Global Markets Inc. ("MSSB")

With respect to Qualifying Shares, UBS Global AM (US), as per a written agreement between both parties, annually pays MSSB no more than the greater of (i) up to 0.16% (16 basis points) of the average daily value of all Qualifying Shares of the Fund or (ii) a minimum of $250,000.00 per year. Qualifying Shares are defined as those shares of the Fund (i) in MSSB accounts and (ii) where MSSB is designated by purchasers as broker-dealer of record. Qualifying Shares do not include any money market shares, or shares, if any, held in the following programs; taxable and non-taxable fee-based advisory programs offered by MSSB and its affiliates, including Morgan Stanley Retirement Solutions Retirement Plan Programs and Variable Annuities.

With respect to Fee Based Shares, UBS Global AM (US), as per a written agreement between both parties, quarterly pays MSSB at the annual rate of up to 0.12% to 0.28% (12 to 28 basis points) of the average daily value of the Fee Based Shares. Fee Based Shares are defined as those shares of the Fund (i) in MSSB accounts and (ii) where MSSB is designated by purchasers on the Fund's records as broker-dealer of record and (iii) held in fee-based advisory programs offered by MSSB to taxable accounts but do not include money market shares, or shares, if any, held in certain (but not all) non-taxable fee-based advisory accounts (e.g., those held by pension and profit-sharing plans subject to ERISA, IRAs, public employer pension accounts) and do not include any Qualifying Shares. Qualifying Shares include both domestic and offshore mutual funds.

Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch")

With respect to Fund Shares, UBS Global AM (US), as per written agreement between both parties, pays Merrill Lynch additional compensation as follows: (i) a fee of 0.25% (25 basis points) of the value of Gross Sales of Fund Shares; and (ii) an annual fee of 0.10% (10 basis points) of the aggregate average daily net asset value of Fund Shares held by Merrill Lynch customers for more than one year (including Fund Shares exchanged for Fund Shares of the Fund for certain other funds in the UBS fund complex).

"Fund Shares" for the purposes of the Merrill Lynch agreement mean all classes of shares of the Fund and certain other funds in the UBS fund complex where Merrill Lynch or any of its affiliates is the record owner or is broker-dealer of record, except (i) shares held in retirement or other benefit accounts under the record-keeping management of Merrill Lynch Retirement Group for which fees are payable by the Advisor to Merrill Lynch pursuant to a services agreement (i.e., not including IRA or similar accounts), and (ii) shares held through Merrill Lynch investment advisory programs. Fund Shares that are no longer held through such Merrill Lynch retirement

54

accounts or investment advisory programs but continue to be held by Merrill Lynch customers will cease to be excluded from the definition of Fund Shares.

"Gross Sales" for the purposes of the Merrill Lynch agreement mean all sales of Fund Shares in which Merrill Lynch or any of its affiliates is record owner or broker-dealer of record, excluding sales of Fund Shares resulting from reinvestment of distributions and exchanges of Fund Shares within the UBS fund complex.

Raymond James & Associates, Inc. and Raymond James Financial Services, Inc. (collectively, "Raymond James")

With respect to Class A, Class C and Class Y qualifying shares (shares sold through Raymond James), UBS Global AM (US), as per a written agreement between the parties, pays Raymond James quarterly at the annual rates as follows: (i) 0.10% (10 basis points) of the average daily value of all qualifying shares of the Fund on assets less than $500 million, (ii) 0.09% (9 basis points) of the average daily value of all qualifying shares of the Fund on assets greater than $500 million but less than $1 billion, (iii) 0.08% (8 basis points) of the average daily value of all qualifying shares of the Fund on assets greater than $1 billion but less than $5 billion and (iv) 0.07% (7 basis points) of the average daily value of all qualifying shares of the Fund on assets greater than $5 billion. The foregoing payments are subject to a minimum payment to Raymond James of $15,000 per year.

Wells Fargo Advisors, LLC, Wells Fargo Advisors Financial Network, LLC, First Clearing, LLC (collectively, "Wells Fargo")

With respect to Fund Shares, UBS Global AM (US), per written agreement between said parties, pays Wells Fargo additional compensation as follows: (i) an annual fee of 0.13% (13 basis points), payable quarterly, on the total assets under management for the Fund held by Wells Fargo's customers or (ii) $50,000, whichever is greater. "Fund Shares" for purposes of the Wells Fargo agreement means all classes of shares of the Fund and certain other funds in the UBS Fund complex where Wells Fargo is the broker-dealer of record. This applies to both retail and advisory assets but does not apply to advisory fee based ERISA accounts. It does apply, however, to individual retirement accounts not covered by ERISA.

The foregoing payments are made by UBS Global AM (US) out of its own resources. Such payments are often referred to as "revenue sharing."

Additional information regarding purchases through letter of intent

To the extent that an investor purchases less than the dollar amount indicated on the Letter of Intent within the 13-month period, the sales charge will be adjusted upward for the entire amount purchased at the end of the 13-month period. This adjustment will be made by redeeming shares first from amounts held in escrow, and then from the account to cover the additional sales charge, the proceeds of which will be paid to the investor's investment professional and UBS Global Asset Management, as applicable, in accordance with the prospectus.

Letters of Intent are not available for certain employee benefit plans.

Additional exchange and redemption information. As discussed in the Prospectus, eligible shares of the Fund may be exchanged for shares of the corresponding class of other series of the Trust and most other Family Funds. Class Y shares are not eligible for exchange.

Shareholders will receive at least 60 days' notice of any termination or material modification of the exchange offer, except no notice need be given if, under extraordinary circumstances, either redemptions are suspended

55

under the circumstances described below or the Fund temporarily delays or ceases the sales of its shares because it is unable to invest amounts effectively in accordance with the Fund's investment objective, policies and restrictions.

The Trust will satisfy redemption requests in cash to the fullest extent feasible, so long as such payments would not, in the opinion of the Advisor or the Board, result in the necessity of the Fund selling assets under disadvantageous conditions and to the detriment of the remaining shareholders of the Fund. Pursuant to the Trust's Agreement and Declaration of Trust, payment for shares redeemed may be made either in cash or in-kind, or partly in cash and partly in-kind. Under unusual circumstances, when the Board deems it in the best interest of the Fund's shareholders, the Trust may make payment for shares repurchased or redeemed in whole or in part in securities of the Fund taken at current values. With respect to such redemptions in kind, the Trust has made an election pursuant to Rule 18f-1 under the Act. This will require the Trust to redeem in cash at a shareholder's election in any case where the redemption involves less than $250,000 (or 1% of the Fund's net asset value at the beginning of each 90-day period during which such redemptions are in effect, if that amount is less than $250,000), during any 90-day period for any one shareholder. Should payment be made in securities, the redeeming shareholder may incur brokerage costs in converting such securities to cash. In-kind payments to non-affiliated shareholders need not constitute a cross-section of the Fund's portfolio. Where a shareholder has requested redemption of all or a part of the shareholder's investment and where the Fund computes such redemption in-kind, the Fund will not recognize gain or loss for federal tax purposes on the securities used to compute the redemption, but the shareholder will recognize gain or loss equal to the difference between the fair market value of the securities received and the shareholder's basis in the Fund shares redeemed. Pursuant to redemption in-kind procedures adopted by the Board on behalf of the Fund, the Trust is permitted to pay redemptions in-kind to shareholders that are affiliated persons of the Fund by nature of a greater than 5% ownership interest in the Fund.

The Fund may suspend redemption privileges or postpone the date of payment during any period (1) when the New York Stock Exchange ("NYSE") is closed or trading on the NYSE is restricted as determined by the SEC, (2) when an emergency exists, as defined by the SEC, that makes it not reasonably practicable for the Fund to dispose of securities owned by it or to determine fairly the value of its assets, or (3) as the SEC may otherwise permit. The redemption price may be more or less than the shareholder's cost, depending on the market value of the Fund's portfolio at the time.

Financial institutions. The Fund may authorize financial institutions, or their agents, to accept on the Fund's behalf purchase and redemption orders that are in "good form" in accordance with the policies of those institutions. The Fund will be deemed to have received these purchase and redemption orders when such financial institution or its agent accepts them. Like all customer orders, these orders will be priced based on the Fund's net asset value next computed after receipt of the order by the financial institutions or their agents. Financial institutions may include retirement plan service providers who aggregate purchase and redemption instructions received from numerous retirement plans or plan participants.

Automatic investment plan—Class A and Class C shares. The Underwriter or your investment professional offers an automatic investment plan with a minimum initial investment of $1,000 through which the Fund will deduct $50 or more on a monthly, quarterly, semiannual or annual basis from the investor's bank account to invest directly in the Fund's Class A or Class C shares. In addition to providing a convenient and disciplined manner of investing, participation in the automatic investment plan enables an investor to use the technique of "dollar cost averaging." When a shareholder invests the same dollar amount each month under the plan, the shareholder will purchase more shares when the Fund's net asset value per share is low and fewer shares when the net asset value per share is high. Using this technique, a shareholder's average purchase price per share over any given period will be lower than if the shareholder purchased a fixed

56

number of shares on a monthly basis during the period. Of course, investing through the automatic investment plan does not assure a profit or protect against loss in declining markets. Additionally, because the automatic investment plan involves continuous investing regardless of price levels, an investor should consider his or her financial ability to continue purchases through periods of both low and high price levels. An investor should also consider whether a large, single investment would qualify for sales load reductions.

Automatic cash withdrawal plan—Class A and Class C

The Automatic Cash Withdrawal Plan allows investors to set up monthly, quarterly (March, June, September and December), semiannual (June and December) or annual (December) withdrawals from their Family Fund accounts. Minimum balances and withdrawals vary according to the class of shares:

•  Class A and Class C shares. Minimum value of Fund shares is $5,000; minimum withdrawals of $100.

Withdrawals under the Automatic Cash Withdrawal Plan will not be subject to a contingent deferred sales charge if the investor withdraws no more than 12% of the value of the Fund account when the shareholder signed up for the plan (for Class A and Class C shares, during the first year under the plan). Shareholders who elect to receive dividends or other distributions in cash may not participate in the plan.

An investor's participation in the Automatic Cash Withdrawal Plan will terminate automatically if the "Initial Account Balance" (a term that means the value of the Fund account at the time the shareholder elects to participate in the Automatic Cash Withdrawal Plan), less aggregate redemptions made other than pursuant to the Automatic Cash Withdrawal Plan, is less than the minimum values specified above. Purchases of additional shares of the Fund concurrent with withdrawals are ordinarily disadvantageous to shareholders because of tax liabilities and, for Class A shares, initial sales charges. On or about the 20th of a month for monthly, quarterly and semiannual plans, your investment professional will arrange for redemption by the Fund of sufficient Fund shares to provide the withdrawal payments specified by participants in the Automatic Cash Withdrawal Plan. The payments generally are mailed approximately five Business Days (defined under "Net Asset Value") after the redemption date. Withdrawal payments should not be considered dividends, but redemption proceeds. If periodic withdrawals continually exceed reinvested dividends and other distributions, a shareholder's investment may be correspondingly reduced. A shareholder may change the amount of the automatic cash withdrawal or terminate participation in the Automatic Cash Withdrawal Plan at any time without charge or penalty by written instructions with signatures guaranteed to your investment professional or BNY Mellon. Instructions to participate in the plan, change the withdrawal amount or terminate participation in the plan will not be effective until five days after written instructions with signatures guaranteed are received by BNY Mellon. Shareholders may request the forms needed to establish an Automatic Cash Withdrawal Plan from their investment professionals or BNY Mellon at 1-800-647 1568.

Individual retirement accounts

Self-directed IRAs are available in which purchases of shares of Family Funds and other investments may be made. Investors considering establishing an IRA should review applicable tax laws and should consult their tax advisors.

Transfer of securities

At the discretion of the Trust, investors may be permitted to purchase Fund shares by transferring securities to the Fund that meet the Fund's investment objective and policies. Securities transferred to the Fund will be valued in accordance with the same procedures used to determine the Fund's net asset value at the time of the next determination of net asset value after such acceptance. Shares issued by the Fund in exchange for securities will be issued at net asset value per share of the Fund determined as of the same time. All dividends, interest, subscription or other rights pertaining to such securities shall become the property of the

57

Fund and must be delivered to the Fund by the investor upon receipt from the issuer. Investors who are permitted to transfer such securities will be required to recognize a gain or loss on such transfer and pay tax thereon, if applicable, measured by the difference between the fair market value of the securities and the investors' basis therein. Securities will not be accepted in exchange for shares of the Fund unless: (1) such securities are, at the time of the exchange, eligible to be included in the Fund's portfolio and current market quotations are readily available for such securities; (2) the investor represents and warrants that all securities offered to be exchanged are not subject to any restrictions upon their sale by the Fund under the 1933 Act, or under the laws of the country in which the principal market for such securities exists, or otherwise; and (3) the value of any such security (except US government securities) being exchanged, together with other securities of the same issuer owned by the Fund, will not exceed 5% of the Fund's net assets immediately after the transaction.

Valuation of shares

The Fund determines its net asset value per share separately for each class of shares, normally as of the close of regular trading (usually 4:00 p.m., Eastern time) on the NYSE on each Business Day when the NYSE is open. Prices will be calculated earlier when the NYSE closes early because trading has been halted for the day. Currently the NYSE is open for trading every day (each such day a "Business Day") except Saturdays, Sundays and the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

The Fund calculates its net asset value based on the current market value, where available, for its portfolio securities. The Fund normally obtains market values for its securities and other instruments 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 "matrix" systems that derive values based on comparable securities or instruments. A matrix 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 securities or instruments. Securities and other instruments also may be valued based on appraisals derived from information concerning the security or instrument or similar securities or instruments received from recognized dealers in those holdings. Securities and instruments 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. Securities and instruments 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. In cases where securities or instruments are traded on more than one exchange, the securities or instruments are valued on the exchange designated as the primary market by the Advisor. If a market value is not readily available from an independent pricing source for a particular security or instrument, that security or instrument is valued at fair value as determined in good faith by or under the direction of the Board. Various factors may be reviewed in order to make a good faith determination of a security's or instrument'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 securities or instruments; and the evaluation of forces which influence the market in which the securities or instruments are purchased and sold. Foreign currency exchange rates are generally determined as of the close of the NYSE.

Certain securities or instruments in which the Fund invests are 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.,

58

Eastern time, will not be 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 securities or instruments, the Fund may adjust the previous closing prices to reflect what the Board believes to be the fair value of these securities or instruments 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 securities 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 a security or instrument is valued at a "fair value," that value is likely to be different from the last quoted market price for the security or instrument.

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, investments in non-registered investment companies are also valued at the daily net asset value. All investments quoted in foreign currencies will be 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 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 and the change in value, if any, is recorded as an unrealized gain or loss on the Statement of assets and liabilities. 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.

Taxes

The following is a summary of certain additional tax considerations generally affecting the Fund and its shareholders that are not described in the Prospectus. No attempt is made to present a detailed explanation of the tax treatment of the Fund or its shareholders, and the discussion here and in the Prospectus is not intended as a substitute for careful tax planning.

This "Taxes" section is based on the Code and applicable regulations in effect on the date of this SAI. Future legislative, regulatory or administrative changes, including provisions of current law that sunset and thereafter no longer apply, or court decisions may significantly change the tax rules applicable to the Fund and its shareholders. Any of these changes or court decisions may have a retroactive effect.

This is for general information only and not tax advice. All investors should consult their own tax advisors as to the federal, state, local and foreign tax provisions applicable to them.

Taxation of the Fund

The Fund has elected and intends to qualify each year as a regulated investment company (sometimes referred to as a "regulated investment company," "RIC" or "fund") under Subchapter M of the Code. If the

59

Fund so qualifies, the Fund will not be subject to federal income tax on the portion of its investment company taxable income (that is, generally, taxable interest, dividends, net short-term capital gains, and other taxable ordinary income, net of expenses, without regard to the deduction for dividends paid) and net capital gain (that is, the excess of net long-term capital gains over net short-term capital losses) that it distributes to shareholders.

In order to qualify for treatment as a regulated investment company, the Fund must satisfy the following requirements:

•  Distribution requirement—The Fund must distribute an amount equal to the sum of at least 90% of its investment company taxable income and 90% of its net tax-exempt income, if any, for the tax year (including, for purposes of satisfying this distribution requirement, certain distributions made by the Fund after the close of its taxable year that are treated as made during such taxable year).

•  Income requirement—The Fund must derive at least 90% of its gross income from dividends, interest, certain payments with respect to securities loans, and gains from the sale or other disposition of stock, securities or foreign currencies, or other income (including, but not limited to, gains from options, futures or forward contracts) derived from its business of investing in such stock, securities or currencies and net income derived from qualified publicly traded partnerships ("QPTPs").

•  Asset diversification test—The Fund must satisfy the following asset diversification test at the close of each quarter of the Fund's tax year: (1) at least 50% of the value of the Fund's assets must consist of cash and cash items, US government securities, securities of other regulated investment companies, and securities of other issuers (as to which the Fund has not invested more than 5% of the value of the Fund's total assets in securities of an issuer and as to which the Fund does not hold more than 10% of the outstanding voting securities of the issuer); and (2) no more than 25% of the value of the Fund's total assets may be invested in the securities of any one issuer (other than US government securities and securities of other regulated investment companies) or of two or more issuers which the Fund controls and which are engaged in the same or similar trades or businesses, or, in the securities of one or more QPTPs.

In some circumstances, the character and timing of income realized by the Fund for purposes of the Income Requirement or the identification of the issuer for purposes of the Asset Diversification Test is uncertain under current law with respect to a particular investment, and an adverse determination or future guidance by the IRS with respect to such type of investment may adversely affect the Fund's ability to satisfy these requirements. See, "Tax Treatment of Portfolio Transactions" below with respect to the application of these requirements to certain types of investments. In other circumstances, the Fund may be required to sell portfolio holdings in order to meet the Income Requirement, Distribution Requirement, or Asset Diversification Test which may have a negative impact on the Fund's income and performance. In lieu of potential disqualification, the Fund is permitted to pay a tax for certain failures to satisfy the Asset Diversification Test or Income Requirement, which, in general, are limited to those due to reasonable cause and not willful neglect.

The Fund may use "equalization accounting" (in lieu of making some cash distributions) in determining the portion of its income and gains that has been distributed. If the Fund uses equalization accounting, it will allocate a portion of its undistributed investment company taxable income and net capital gain to redemptions of Fund shares and will correspondingly reduce the amount of such income and gains that it distributes in cash. If the IRS determines that the Fund's allocation is improper and that the Fund has under-distributed its income and gain for any taxable year, the Fund may be liable for federal income and/or excise tax. If, as a

60

result of such adjustment, the Fund fails to satisfy the Distribution Requirement, the Fund will not qualify that year as a regulated investment company the effect of which is described in the following paragraph.

If for any taxable year the Fund does not qualify as a regulated investment company, all of its taxable income (including its net capital gain) would be subject to tax at regular corporate rates without any deduction for dividends paid to shareholders, and the dividends would be taxable to the shareholders as ordinary income (or possibly as qualified dividend income) to the extent of the Fund's current and accumulated earnings and profits. Failure to qualify as a regulated investment company would thus have a negative impact on the Fund's income and performance. Subject to savings provisions for certain failures to satisfy the Income Requirement or Asset Diversification Test which, in general, are limited to those due to reasonable cause and not willful neglect, it is possible that the Fund will not qualify as a regulated investment company in any given tax year. Even if such savings provisions apply, the Fund may be subject to a monetary sanction of $50,000 or more. Moreover, the Board reserves the right not to maintain the qualification of the Fund as a regulated investment company if it determines such a course of action to be beneficial to shareholders.

Portfolio turnover—For investors that hold their Fund shares in a taxable account, a high portfolio turnover rate may result in higher taxes. This is because a fund with a high turnover rate is likely to accelerate the recognition of capital gains and more of such gains are likely to be taxable as short-term rather than long-term capital gains in contrast to a comparable fund with a low turnover rate. Any such higher taxes would reduce the Fund's after-tax performance. See, "Taxation of Fund distributions—Distributions of capital gains" below. For non-US investors, any such acceleration of the recognition of capital gains that results in more short-term and less long-term capital gains being recognized by the Fund may cause such investors to be subject to increased US withholding taxes. See, "Non-US investors—Capital gain dividends and short-term capital gain dividends" below.

Capital loss carryovers—The capital losses of the Fund, if any, do not flow through to shareholders. Rather, the Fund may use its capital losses, subject to applicable limitations, to offset its capital gains without being required to pay taxes on or distribute to shareholders such gains that are offset by the losses. Under the Regulated Investment Company Modernization Act of 2010 ("RIC Mod Act"), rules similar to those that apply to capital loss carryovers of individuals are made applicable to RICs. Thus, if the Fund has a "net capital loss" (that is, capital losses in excess of capital gains) for a taxable year beginning after December 22, 2010 (the date of enactment of the RIC Mod Act), the excess (if any) of the Fund's net short-term capital losses over its net long-term capital gains is treated as a short-term capital loss arising on the first day of the Fund's next taxable year, and the excess (if any) of the Fund's net long-term capital losses over its net short-term capital gains is treated as a long-term capital loss arising on the first day of the Fund's next taxable year. Any such net capital losses of the Fund that are not used to offset capital gains may be carried forward indefinitely to reduce any future capital gains realized by the Fund in succeeding taxable years. However, for any net capital losses realized in taxable years of the Fund beginning on or before December 22, 2010, the Fund is only permitted to carry forward such capital losses for eight years as a short-term capital loss. Under a transition rule, capital losses arising in a taxable year beginning after December 22, 2010 must be used before capital losses realized in a prior taxable year. The amount of capital losses that can be carried forward and used in any single year is subject to an annual limitation if there is a more than 50% "change in ownership" of the Fund. An ownership change generally results when shareholders owning 5% or more of the Fund increase their aggregate holdings by more than 50% over a three-year look-back period. An ownership change could result in capital loss carryovers being used at a slower rate (or, in the case of those realized in taxable years of the Fund beginning on or before December 22, 2010, to expire unutilized), thereby reducing the Fund's ability to offset capital gains with those losses. An increase in the amount of taxable gains distributed to the Fund's shareholders could result from an ownership change. The Fund undertakes no obligation to avoid or prevent an ownership change, which can occur in the normal course of shareholder purchases and

61

redemptions or as a result of engaging in a tax-free reorganization with another fund. Moreover, because of circumstances beyond the Fund's control, there can be no assurance that the Fund will not experience, or has not already experienced, an ownership change. Additionally, if the Fund engages in a tax-free reorganization with another Fund, the effect of these and other rules not discussed herein may be to disallow or postpone the use by the Fund of its capital loss carryovers (including any current year losses and built-in losses when realized) to offset its own gains or those of the other Fund, or vice versa, thereby reducing the tax benefits Fund shareholders would otherwise have enjoyed from use of such capital loss carryovers.

Deferral of late year losses—The Fund may elect to treat part or all of any "qualified late year loss" as if it had been incurred in the succeeding taxable year in determining the Fund's taxable income, net capital gain, net short-term capital gain, and earnings and profits. The effect of this election is to treat any such "qualified late year loss" as if it had been incurred in the succeeding taxable year in characterizing Fund distributions for any calendar year (see, "Taxation of Fund Distributions—Distributions of capital gains" below). A "qualified late year loss" includes:

(i)  any net capital loss, net long-term capital loss, or net short-term capital loss incurred after October 31 of the current taxable year ("post-October losses"); and

(ii)  the excess, if any, of (1) the sum of (a) specified losses incurred after October 31 of the current taxable year, and (b) other ordinary losses incurred after December 31 of the current taxable year, over (2) the sum of (a) specified gains incurred after October 31 of the current taxable year, and (b) other ordinary gains incurred after December 31 of the current taxable year.

The terms "specified losses" and "specified gains" mean ordinary losses and gains from the sale, exchange, or other disposition of property (including the termination of a position with respect to such property), foreign currency losses and gains, and losses and gains resulting from holding stock in a passive foreign investment company ("PFIC") for which a mark-to-market election is in effect. The terms "ordinary losses" and "ordinary gains" mean other ordinary losses and gains that are not described in the preceding sentence.

Undistributed capital gains—The Fund may retain or distribute to shareholders its net capital gain for each taxable year. The Fund currently intends to distribute net capital gains. If the Fund elects to retain its net capital gain, the Fund will be taxed thereon (except to the extent of any available capital loss carryovers) at the highest corporate tax rate (currently 35%). If the Fund elects to retain its net capital gain, it is expected that the Fund also will elect to have shareholders treated as if each received a distribution of its pro rata share of such gain, with the result that each shareholder will be required to report its pro rata share of such gain on its tax return as long-term capital gain, will receive a refundable tax credit for its pro rata share of tax paid by the Fund on the gain, and will increase the tax basis for its shares by an amount equal to the deemed distribution less the tax credit.

Federal excise tax—To avoid a 4% non-deductible excise tax, the Fund must distribute by December 31 of each year an amount equal to: (1) 98% of its ordinary income for the calendar year, (2) 98.2% of capital gain net income (that is, the excess of the gains from sales or exchanges of capital assets over the losses from such sales or exchanges) for the one-year period ended on October 31 of such calendar year, and (3) any prior year undistributed ordinary income and capital gain net income. The Fund may elect to defer to the following year any net ordinary loss incurred for the portion of the calendar year which is after the beginning of the Fund's taxable year. Also, the Fund will defer any "specified gain" or "specified loss" which would be properly taken into account for the portion of the calendar year after October 31. Any net ordinary loss, specified gain, or specified loss deferred shall be treated as arising on January 1 of the following calendar year. Generally, the Fund intends to make sufficient distributions prior to the end of each calendar

62

year to avoid any material liability for federal income and excise tax, but can give no assurances that all or a portion of such liability will be avoided. In addition, under certain circumstances, temporary timing or permanent differences in the realization of income and expense for book and tax purposes can result in the Fund having to pay an excise tax.

Foreign income tax—Investment income received by the Fund from sources within foreign countries may be subject to foreign income tax withheld at the source and the amount of tax withheld generally will be treated as an expense of the Fund. The United States has entered into tax treaties with many foreign countries, which entitle the Fund to a reduced rate of, or exemption from, tax on such income. It is impossible to determine the effective rate of foreign tax in advance since the amount of the Fund's assets to be invested in various countries is not known. Under certain circumstances, the Fund may elect to pass-through foreign tax credits to shareholders, although it reserves the right not to do so.

Taxation of Fund distributions

The Fund anticipates distributing substantially all of its investment company taxable income and net capital gain for each taxable year. Distributions by the Fund will be treated in the manner described below regardless of whether such distributions are paid in cash or reinvested in additional shares of the Fund (or of another fund). The Fund will send you information annually as to the federal income tax consequences of distributions made (or deemed made) during the year.

Distributions of net investment income—The Fund receives ordinary income generally in the form of dividends and/or interest on its investments. The Fund may also recognize ordinary income from other sources, including, but not limited to, certain gains on foreign currency-related transactions. This income, less expenses incurred in the operation of the Fund, constitutes the Fund's net investment income from which income dividends may be paid to you. The Fund calculates income dividends and capital gains distributions the same way for each class. The amount of any income dividends per share will differ, however, generally due to any differences in the distribution and service (Rule 12b-1) fees applicable to the classes. If you are a taxable investor, distributions of net investment income generally are taxable as ordinary income to the extent of the Fund's earnings and profits. In the case of the Fund whose strategy includes investing in stocks of corporations, a portion of the income dividends paid to you may be qualified dividends eligible to be taxed at reduced rates. See the discussion below under the headings, "—Qualified dividend income for individuals" and "—Dividends-received deduction for corporations."

Distributions of capital gains—The Fund may derive capital gain and loss in connection with sales or other dispositions of its portfolio securities. Distributions derived from the excess of net short-term capital gain over net long-term capital loss will be taxable to you as ordinary income. Distributions paid from the excess of net long-term capital gain over net short-term capital loss will be taxable to you as long-term capital gain, regardless of how long you have held your shares in the Fund. Any net short-term or long-term capital gain realized by a Fund (net of any capital loss carryovers) generally will be distributed once each year and may be distributed more frequently, if necessary, in order to reduce or eliminate federal excise or income taxes on the Fund.

Returns of capital—Distributions by the Fund that are not paid from earnings and profits will be treated as a return of capital to the extent of (and in reduction of) the shareholder's tax basis in his shares; any excess will be treated as gain from the sale of his shares. Thus, the portion of a distribution that constitutes a return of capital will decrease the shareholder's tax basis in his Fund shares (but not below zero), and will result in an increase in the amount of gain (or decrease in the amount of loss) that will be recognized by the shareholder for tax purposes on the later sale of such Fund shares. Return of capital distributions can occur for a number of reasons including, among others, the Fund over-estimates the income to be received from certain

63

investments such as those classified as partnerships or equity real estate investment trusts ("REITs") (see, "Tax treatment of portfolio transactions—Investments in US REITs" below).

Qualified dividend income for individuals—With respect to taxable years of the Fund beginning before January 1, 2013 (unless such provision is extended, possibly retroactively to January 1, 2013, or made permanent), ordinary income dividends reported by the Fund to shareholders as derived from qualified dividend income will be taxed in the hands of individuals and other noncorporate shareholders at the rates applicable to long-term capital gain. "Qualified dividend income" means dividends paid to the Fund (a) by domestic corporations, (b) by foreign corporations that are either (i) incorporated in a possession of the United States, or (ii) are eligible for benefits under certain income tax treaties with the United States that include an exchange of information program, or (c) with respect to stock of a foreign corporation that is readily tradable on an established securities market in the United States. Both the Fund and the investor must meet certain holding period requirements to qualify Fund dividends for this treatment. Specifically, the Fund must hold the stock for at least 61 days during the 121-day period beginning 60 days before the stock becomes ex-dividend. Similarly, investors must hold their Fund shares for at least 61 days during the 121-day period beginning 60 days before the Fund distribution goes ex-dividend. Income derived from investments in derivatives, fixed-income securities, US REITs, PFICs, and income received "in lieu of" dividends in a securities lending transaction generally is not eligible for treatment as qualified dividend income. If the qualifying dividend income received by the Fund is equal to or greater than 95% of the Fund's gross income (exclusive of net capital gain) in any taxable year, all of the ordinary income dividends paid by the Fund will be qualifying dividend income.

Dividends-received deduction for corporations—For corporate shareholders, a portion of the dividends paid by the Fund may qualify for the 70% corporate dividends-received deduction. The portion of dividends paid by the Fund that so qualifies will be reported by the Fund to shareholders each year and cannot exceed the gross amount of dividends received by the Fund from domestic (US) corporations. The availability of the dividends-received deduction is subject to certain holding period and debt financing restrictions that apply to both the Fund and the investor. Specifically, the amount that the Fund may report as eligible for the dividends-received deduction will be reduced or eliminated if the shares on which the dividends earned by the Fund were debt-financed or held by the Fund for less than a minimum period of time, generally 46 days during a 91-day period beginning 45 days before the stock becomes ex-dividend. Similarly, if your Fund shares are debt-financed or held by you for less than a 46-day period then the dividends-received deduction for Fund dividends on your shares may also be reduced or eliminated. Even if reported as dividends eligible for the dividends-received deduction, all dividends (including any deducted portion) must be included in your alternative minimum taxable income calculation. Income derived by the Fund from investments in derivatives, fixed-income and foreign securities generally is not eligible for this treatment.

Impact of realized but undistributed income and gains, and net unrealized appreciation of portfolio securities—At the time of your purchase of shares, the Fund's net asset value may reflect undistributed income, undistributed capital gains, or net unrealized appreciation of portfolio securities held by the Fund. A subsequent distribution to you of such amounts, although constituting a return of your investment, would be taxable, and would be taxed as ordinary income (some portion of which may be taxed as qualified dividend income), capital gains, or some combination of both, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account. The Fund may be able to reduce the amount of such distributions from capital gains by utilizing its capital loss carryovers, if any.

Pass-through of foreign tax credits—If more than 50% of the Fund's total assets at the end of a fiscal year is invested in foreign securities, the Fund may elect to pass-through to you your pro rata share of foreign taxes paid by the Fund. If this election is made, the Fund may report more taxable income to you than it actually

64

distributes. You will then be entitled either to deduct your share of these taxes in computing your taxable income, or to claim a foreign tax credit for these taxes against your US federal income tax (subject to limitations for certain shareholders). The Fund will provide you with the information necessary to claim this deduction or credit on your personal income tax return if it makes this election. No deduction for foreign tax may be claimed by a noncorporate shareholder who does not itemize deductions or who is subject to the alternative minimum tax. Shareholders may be unable to claim a credit for the full amount of their proportionate shares of the foreign income tax paid by the Fund due to certain limitations that may apply. The Fund reserves the right not to pass-through to its shareholders the amount of foreign income taxes paid by the Fund. Additionally, any foreign tax withheld on payments made "in lieu of" dividends or interest will not qualify for the pass-through of foreign tax credits to shareholders. See, "Tax treatment of portfolio transactions—Securities lending" below.

US government securities—Income earned on certain US government obligations is exempt from state and local personal income taxes if earned directly by you. States also grant tax-free status to dividends paid to you from interest earned on direct obligations of the US government, subject in some states to minimum investment or reporting requirements that must be met by the Fund. Income on investments by the Fund in certain other obligations, such as repurchase agreements collateralized by US government obligations, commercial paper and federal agency-backed obligations (e.g., Ginnie Mae or Fannie Mae securities), generally does not qualify for tax-free treatment. The rules on exclusion of this income are different for corporations.

Dividends declared in December and paid in January—Ordinarily, shareholders are required to take distributions by the Fund into account in the year in which the distributions are made. However, dividends declared in October, November or December of any year and payable to shareholders of record on a specified date in such a month will be deemed to have been received by the shareholders (and made by the Fund) on December 31 of such calendar year if such dividends are actually paid in January of the following year. Shareholders will be advised annually as to the US federal income tax consequences of distributions made (or deemed made) during the year in accordance with the guidance that has been provided by the IRS.

Medicare tax—The recently enacted Patient Protection and Affordable Care Act of 2010, as amended by the Health Care and Education Affordability Reconciliation Act of 2010, will impose a 3.8% Medicare tax on net investment income earned by certain individuals, estates and trusts for taxable years beginning after December 31, 2012. "Net investment income," for these purposes, means investment income, including ordinary dividends and capital gain distributions received from the Fund and net gains from redemptions or other taxable dispositions of Fund shares, reduced by the deductions properly allocable to such income. In the case of an individual, the tax will be imposed on the lesser of (1) the shareholder's net investment income or (2) the amount by which the shareholder's modified adjusted gross income exceeds $250,000 (if the shareholder is married and filing jointly or a surviving spouse), $125,000 (if the shareholder is married and filing separately) or $200,000 (in any other case).

Sales, exchanges and redemption of Fund shares

Sales, exchanges and redemptions (including redemptions in kind) of Fund shares are taxable transactions for federal and state income tax purposes. If you redeem your Fund shares, the Internal Revenue Service requires you to report any gain or loss on your redemption. If you held your shares as a capital asset, the gain or loss that you realize will be a capital gain or loss and will be long-term or short-term, generally depending on how long you have held your shares. Any redemption fees you incur on shares redeemed will decrease the amount of any capital gain (or increase any capital loss) you realize on the sale. Capital losses in any year are deductible only to the extent of capital gains plus, in the case of a noncorporate taxpayer, $3,000 of ordinary income.

65

Tax basis information—Unless you are investing in the Fund through a tax-advantaged retirement account, such as a 401(k) plan or an individual retirement account, or a money market account, the Fund is required to report to you and the IRS annually on Form 1099-B the cost basis of shares purchased or acquired on or after January 1, 2012 where the cost basis of the shares is known by the Fund (referred to as "covered shares") and which are disposed of after that date. Cost basis will be calculated using the Fund's default method of average cost, unless you instruct the Fund in writing to use a different calculation method. In general, average cost is the total cost basis of all your shares in an account divided by the total number of shares in the account. To determine whether short-term or long-term capital gains taxes apply, the IRS presumes you redeem your oldest shares first.

The IRS permits the use of several methods to determine the cost basis of mutual fund shares. The method used will determine which specific shares are deemed to be sold when there are multiple purchases on different dates at differing share prices, and the entire position is not sold at one time. The Fund does not recommend any particular method of determining cost basis, and the use of other methods may result in more favorable tax consequences for some shareholders. It is important that you consult with your tax advisor to determine which method is best for you and then notify the Fund in writing if you intend to utilize a method other than average cost for covered shares.

In addition to the Fund's default method of average cost, other cost basis methods offered by The UBS Funds, which you may elect to apply to covered shares, include:

•  First-In, First-Out (FIFO)—shares acquired first in the account are the first shares depleted.

•  Last-In, First-Out (LIFO)—shares acquired last in the account are the first shares depleted.

•  Highest Cost In, First Out (HIFO)—shares acquired with the highest cost per share are the first shares depleted.

•  Lowest Cost In, First Out (LOFO)—shares acquired with the lowest cost per share are the first shares depleted.

•  Highest Cost Long-Term In, First Out (HILT)—long-term shares with the highest cost per share are the first shares depleted.

•  Highest Cost Short-Term In, First Out (HIST)—short-term shares with the highest cost per share are the first shares depleted.

•  Lowest Cost Long-Term In, First out (LILT)—long-term shares with the lowest cost per share are the first shares depleted.

•  Lowest Cost Short-Term In, First out (LIST)—short-term shares with the lowest cost per share are the first shares depleted.

•  Specific Lot Identification—shareholder selects which lots to deplete at time of each disposition. Transaction amount must be in shares. If you identify an insufficient number of shares or do not make a timely identification, the transaction will default to the first-in, first-out method.

You may elect any of the available methods detailed above for your covered shares. If you do not notify the Fund in writing of your elected cost basis method upon the later of January 1, 2012 or the initial purchase

66

into your account, the default method of average cost will be applied to your covered shares. The cost basis for covered shares will be calculated separately from any shares purchased prior to January 1, 2012 or shares acquired on or after January 1, 2012 for which cost basis information is not known by the Fund ("noncovered shares") you may own. You may change or revoke the use of the average cost method and elect another cost basis method for covered shares if you notify the Fund in writing. You may change from average cost to another cost basis method for covered shares at any time, but only for shares acquired after the date of the change (the change is prospective). The basis of the shares that were averaged before the change will remain averaged after the date of the change.

With the exception of the specific lot identification method, The UBS Funds first depletes noncovered shares in first-in, first-out order before applying your elected method to your remaining covered shares. If you want to deplete your shares in a different order then you must elect specific lot identification and choose the lots you wish to deplete first.

The Fund will compute and report the cost basis of your Fund shares sold or exchanged by taking into account all of the applicable adjustments to cost basis and holding periods as required by the Code and Treasury regulations for purposes of reporting these amounts to you and the IRS. However, the Fund is not required to, and in many cases the Fund does not possess the information to, take all possible basis, holding period or other adjustments into account in reporting cost basis information to you. Therefore shareholders should carefully review the cost basis information provided by the Fund, and make any additional basis, holding period or other adjustments that are required by the Code and Treasury regulations when reporting these amounts on their federal income tax returns. Shareholders remain solely responsible for complying with all federal income tax laws when filing their federal income tax returns.

If you hold your Fund shares through a broker (or other nominee), please contact that broker (nominee) with respect to reporting of cost basis and available elections for your account.

Wash sales—All or a portion of any loss that you realize on a redemption of your Fund shares will be disallowed to the extent that you buy other shares in the Fund (through reinvestment of dividends or otherwise) within 30 days before or after your share redemption. Any loss disallowed under these rules will be added to your tax basis in the new shares.

Redemptions at a loss within six months of purchase—Any loss incurred on a redemption or exchange of shares held for six months or less will be treated as long-term capital loss to the extent of any long-term capital gain distributed to you by the Fund on those shares.

Special rule for Class A shareholders—If a shareholder (a) incurs a sales load in acquiring shares of the Fund, (b) disposes of such shares less than 91 days after they are acquired, and (c) subsequently acquires shares of the Fund or another Fund by January 31 of the calendar year following the calendar year in which the disposition of the original shares occurred at a reduced sales load pursuant to a right to reinvest at such reduced sales load acquired in connection with the acquisition of the shares disposed of, then the sales load on the shares disposed of (to the extent of the reduction in the sales load on the shares subsequently acquired) shall not be taken into account in determining gain or loss on the shares disposed of, but shall be treated as incurred on the acquisition of the shares subsequently acquired. The wash sale rules may also limit the amount of loss that may be taken into account on disposition after such adjustment.

Tax shelter reporting—Under Treasury regulations, if a shareholder recognizes a loss with respect to the Fund's shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder must file with the Internal Revenue Service a disclosure statement on Form 8886.

67

Tax treatment of portfolio transactions

Set forth below is a general description of the tax treatment of certain types of securities, investment techniques and transactions that may apply to a fund and, in turn, affect the amount, character and timing of dividends and distributions payable by the fund to its shareholders. This section should be read in conjunction with the sections above for a detailed description of the various types of securities and investment techniques that apply to the Fund.

In general—In general, gain or loss recognized by a fund on the sale or other disposition of portfolio investments will be a capital gain or loss. Such capital gain and loss may be long-term or short-term depending, in general, upon the length of time a particular investment position is maintained and, in some cases, upon the nature of the transaction. Property held for more than one year generally will be eligible for long-term capital gain or loss treatment. The application of certain rules described below may serve to alter the manner in which the holding period for a security is determined or may otherwise affect the characterization as long-term or short-term, and also the timing of the realization and/or character, of certain gains or losses.

Certain fixed-income investments—Gain recognized on the disposition of a debt obligation purchased by a fund at a market discount (generally, at a price less than its principal amount) will be treated as ordinary income to the extent of the portion of the market discount which accrued during the period of time the fund held the debt obligation unless the fund made a current inclusion election to accrue market discount into income as it accrues. If a fund purchases a debt obligation (such as a zero coupon security or pay-in-kind security) that was originally issued at a discount, the fund generally is required to include in gross income each year the portion of the original issue discount which accrues during such year. Therefore, a fund's investment in such securities may cause the fund to recognize income and make distributions to shareholders before it receives any cash payments on the securities. To generate cash to satisfy those distribution requirements, a fund may have to sell portfolio securities that it otherwise might have continued to hold or to use cash flows from other sources such as the sale of fund shares.

Investments in debt obligations that are at risk of or in default present tax issues for a fund—Tax rules are not entirely clear about issues such as whether and to what extent a fund should recognize market discount on a debt obligation, when a fund may cease to accrue interest, original issue discount or market discount, when and to what extent a fund may take deductions for bad debts or worthless securities and how a fund should allocate payments received on obligations in default between principal and income. These and other related issues will be addressed by a fund in order to ensure that it distributes sufficient income to preserve its status as a regulated investment company.

Options, futures, forward contracts, swap agreements and hedging transactions—In general, option premiums received by a fund are not immediately included in the income of the fund. Instead, the premiums are recognized when the option contract expires, the option is exercised by the holder, or the fund transfers or otherwise terminates the option (e.g., through a closing transaction). If an option written by a fund is exercised and the fund sells or delivers the underlying stock, the fund generally will recognize capital gain or loss equal to (a) sum of the strike price and the option premium received by the fund minus (b) the fund's basis in the stock. Such gain or loss generally will be short-term or long-term depending upon the holding period of the underlying stock. If securities are purchased by a fund pursuant to the exercise of a put option written by it, the fund generally will subtract the premium received from its cost basis in the securities purchased. The gain or loss with respect to any termination of a fund's obligation under an option other than through the exercise of the option and related sale or delivery of the underlying stock generally will be short-term gain or loss depending on whether the premium income received by the fund is greater or less than the

68

amount paid by the fund (if any) in terminating the transaction. Thus, for example, if an option written by a fund expires unexercised, the fund generally will recognize short-term gain equal to the premium received.

The tax treatment of certain futures contracts entered into by a fund as well as listed non-equity options written or purchased by the fund on US exchanges (including options on futures contracts, broad-based equity indices and debt securities) may be governed by section 1256 of the Code ("section 1256 contracts"). Gains or losses on section 1256 contracts generally are considered 60% long-term and 40% short-term capital gains or losses ("60/40"), although certain foreign currency gains and losses from such contracts may be treated as ordinary in character. Also, any section 1256 contracts held by a fund at the end of each taxable year (and, for purposes of the 4% excise tax, on certain other dates as prescribed under the Code) are "marked to market" with the result that unrealized gains or losses are treated as though they were realized and the resulting gain or loss is treated as ordinary or 60/40 gain or loss, as applicable. Section 1256 contracts do not include any interest rate swap, currency swap, basis swap, interest rate cap, interest rate floor, commodity swap, equity swap, equity index swap, credit default swap, or similar agreement.

In addition to the special rules described above in respect of options and futures transactions, a fund's transactions in other derivative instruments (including options, forward contracts and swap agreements) as well as its other hedging, short sale, or similar transactions, may be subject to one or more special tax rules (including the constructive sale, notional principal contract, straddle, wash sale and short sale rules). These rules may affect whether gains and losses recognized by a fund are treated as ordinary or capital or as short-term or long-term, accelerate the recognition of income or gains to the fund, defer losses to the fund, and cause adjustments in the holding periods of the fund's securities. These rules, therefore, could affect the amount, timing and/or character of distributions to shareholders. Moreover, because the tax rules applicable to derivative financial instruments are in some cases uncertain under current law, an adverse determination or future guidance by the IRS with respect to these rules (which determination or guidance could be retroactive) may affect whether a fund has made sufficient distributions, and otherwise satisfied the relevant requirements, to maintain its qualification as a regulated investment company and avoid a fund-level tax.

Certain of a fund's investments in derivatives and foreign currency-denominated instruments, and the fund's transactions in foreign currencies and hedging activities, may produce a difference between its book income and its taxable income. If a fund's book income is less than the sum of its taxable income and net tax-exempt income (if any), the fund could be required to make distributions exceeding book income to qualify as a regulated investment company. If a fund's book income exceeds the sum of its taxable income and net tax-exempt income (if any), the distribution of any such excess will be treated as (i) a dividend to the extent of the fund's remaining earnings and profits (including current earnings and profits arising from tax-exempt income, reduced by related deductions), (ii) thereafter, as a return of capital to the extent of the recipient's basis in the shares, and (iii) thereafter, as gain from the sale or exchange of a capital asset.

Foreign currency transactions—A fund's transactions in foreign currencies, foreign currency-denominated debt obligations and certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This treatment could increase or decrease a fund's ordinary income distributions to you, and may cause some or all of the fund's previously distributed income to be classified as a return of capital. In certain cases, a fund may make an election to treat such gain or loss as capital.

PFIC investments—A fund may invest in stocks of foreign companies that may be classified under the Code as PFICs. In general, a foreign company is classified as a PFIC if at least one-half of its assets constitute investment-type assets or 75% or more of its gross income is investment-type income. When investing in PFIC securities, a fund intends to mark-to-market these securities under certain provisions of the Code and

69

recognize any unrealized gains as ordinary income at the end of the fund's fiscal and excise tax years. Deductions for losses are allowable only to the extent of any current or previously recognized gains. These gains (reduced by allowable losses) are treated as ordinary income that a fund is required to distribute, even though it has not sold or received dividends from these securities. You should also be aware that the designation of a foreign security as a PFIC security will cause its income dividends to fall outside of the definition of qualified foreign corporation dividends. These dividends generally will not qualify for the reduced rate of taxation on qualified dividends when distributed to you by a fund. Foreign companies are not required to identify themselves as PFICs. Due to various complexities in identifying PFICs, a fund can give no assurances that it will be able to identify portfolio securities in foreign corporations that are PFICs in time for the fund to make a mark-to-market election. If a fund is unable to identify an investment as a PFIC and thus does not make a mark-to-market election, the fund may be subject to US federal income tax on a portion of any "excess distribution" or gain from the disposition of such shares even if such income is distributed as a taxable dividend by the fund to its shareholders. Additional charges in the nature of interest may be imposed on a fund in respect of deferred taxes arising from such distributions or gains.

Investments in US REITs—A US REIT is not subject to federal income tax on the income and gains it distributes to shareholders. Dividends paid by a US REIT, other than capital gain distributions, will be taxable as ordinary income up to the amount of the US REIT's current and accumulated earnings and profits. Capital gain dividends paid by a US REIT to a fund will be treated as long term capital gains by the fund and, in turn, may be distributed by the fund to its shareholders as a capital gain distribution. Because of certain noncash expenses, such as property depreciation, an equity US REIT's cash flow may exceed its taxable income. The equity US REIT, and in turn a fund, may distribute this excess cash to shareholders in the form of a return of capital distribution. However, if a US REIT is operated in a manner that fails to qualify as a REIT, an investment in the US REIT would become subject to double taxation, meaning the taxable income of the US REIT would be subject to federal income tax at regular corporate rates without any deduction for dividends paid to shareholders and the dividends would be taxable to shareholders as ordinary income (or possibly as qualified dividend income) to the extent of the US REIT's current and accumulated earnings and profits. Also, see, "Tax treatment of portfolio transactions—Investment in taxable mortgage pools (excess inclusion income)" and "Non-US investors—Investment in US real property" below with respect to certain other tax aspects of investing in US REITs.

Investment in non-US REITs—While non-US REITs often use complex acquisition structures that seek to minimize taxation in the source country, an investment by a fund in a non-US REIT may subject the fund, directly or indirectly, to corporate taxes, withholding taxes, transfer taxes and other indirect taxes in the country in which the real estate acquired by the non-US REIT is located. A fund's pro rata share of any such taxes will reduce the fund's return on its investment. A fund's investment in a non-US REIT may be considered an investment in a PFIC, as discussed above in "PFIC investments." Additionally, foreign withholding taxes on distributions from the non-US REIT may be reduced or eliminated under certain tax treaties, as discussed above in "Taxation of the Fund—Foreign income tax." Also, a fund in certain limited circumstances may be required to file an income tax return in the source country and pay tax on any gain realized from its investment in the non-US REIT under rules similar to those in the United States which tax foreign persons on gain realized from dispositions of interests in US real estate.

Investment in taxable mortgage pools (excess inclusion income)—Under a Notice issued by the IRS, the Code and Treasury regulations to be issued, a portion of a fund's income from a US REIT that is attributable to the REIT's residual interest in a real estate mortgage investment conduit ("REMIC") or equity interests in a "taxable mortgage pool" (referred to in the Code as an excess inclusion) will be subject to federal income tax in all events. The excess inclusion income of a regulated investment company, such as a fund, will be allocated to shareholders of the regulated investment company in proportion to the dividends received by

70

such shareholders, with the same consequences as if the shareholders held the related REMIC residual interest or, if applicable, taxable mortgage pool directly. In general, excess inclusion income allocated to shareholders (i) cannot be offset by net operating losses (subject to a limited exception for certain thrift institutions), (ii) will constitute unrelated business taxable income ("UBTI") to entities (including qualified pension plans, individual retirement accounts, 401(k) plans, Keogh plans or other tax-exempt entities) subject to tax on UBTI, thereby potentially requiring such an entity that is allocated excess inclusion income, and otherwise might not be required to file a tax return, to file a tax return and pay tax on such income, and (iii) in the case of a foreign stockholder, will not qualify for any reduction in US federal withholding tax. In addition, if at any time during any taxable year a "disqualified organization" (which generally includes certain cooperatives, governmental entities, and tax-exempt organizations not subject to UBTI) is a record holder of a share in a regulated investment company, then the regulated investment company will be subject to a tax equal to that portion of its excess inclusion income for the taxable year that is allocable to the disqualified organization, multiplied by the highest federal income tax rate imposed on corporations. The Notice imposes certain reporting requirements upon regulated investment companies that have excess inclusion income.

There can be no assurance that a fund will not allocate to shareholders excess inclusion income. These rules are potentially applicable to a fund with respect to any income it receives from the equity interests of certain mortgage pooling vehicles, either directly or, as is more likely, through an investment in a US REIT. It is unlikely that these rules will apply to a fund that has a non-REIT strategy.

Investments in partnerships and QPTPs—For purposes of the Income Requirement, income derived by a fund from a partnership that is not a QPTP will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership that would be qualifying income if realized directly by the fund. For purposes of testing whether a fund satisfies the Asset Diversification Test, the fund generally is treated as owning a pro rata share of the underlying assets of a partnership. See, "Taxation of the Fund." In contrast, different rules apply to a partnership that is a QPTP. A QPTP is a partnership (a) the interests in which are traded on an established securities market, (b) that is treated as a partnership for federal income tax purposes, and (c) that derives less than 90% of its income from sources that satisfy the Income Requirement (e.g., because it invests in commodities). All of the net income derived by a fund from an interest in a QPTP will be treated as qualifying income but the fund may not invest more than 25% of its total assets in one or more QPTPs. However, there can be no assurance that a partnership classified as a QPTP in one year will qualify as a QPTP in the next year. Any such failure to annually qualify as a QPTP might, in turn, cause a fund to fail to qualify as a regulated investment company. Although, in general, the passive loss rules of the Code do not apply to RICs, such rules do apply to a fund with respect to items attributable to an interest in a QPTP. Fund investments in partnerships, including in QPTPs, may result in the fund's being subject to state, local or foreign income, franchise or withholding tax liabilities.

Investments in commodities—structured notes, corporate subsidiary and certain ETFs—Gains from the disposition of commodities, including precious metals, will neither be considered qualifying income for purposes of satisfying the Income Requirement nor qualifying assets for purposes of satisfying the Asset Diversification Test. See, "Taxation of the Fund." Also, the IRS has issued a revenue ruling which holds that income derived from commodity-linked swaps is not qualifying income for purposes of the Income Requirement. However, in a subsequent revenue ruling, the IRS provides that income from certain alternative investments which create commodity exposure, such as certain commodity index-linked or structured notes or a corporate subsidiary that invests in commodities, may be considered qualifying income under the Code. In addition, a fund may gain exposure to commodities through investment in QPTPs such as an exchange traded fund or ETF that is classified as a partnership and which invests in commodities. Accordingly, the extent to which a fund invests in commodities or commodity-linked derivatives may be limited by the Income

71

Requirement and the Asset Diversification Test, which the fund must continue to satisfy to maintain its status as a regulated investment company. A fund also may be limited in its ability to sell its investments in commodities, commodity-linked derivatives, and certain ETFs or be forced to sell other investments to generate income due to the Income Requirement.

Securities lending—While securities are loaned out by a fund, the fund generally will receive from the borrower amounts equal to any dividends or interest paid on the borrowed securities. For federal income tax purposes, payments made "in lieu of" dividends are not considered dividend income. These distributions will neither qualify for the reduced rate of taxation for individuals on qualified dividends nor the 70% dividends received deduction for corporations. Also, any foreign tax withheld on payments made "in lieu of" dividends or interest will not qualify for the pass-through of foreign tax credits to shareholders.

Investments in convertible securities—Convertible debt is ordinarily treated as a "single property" consisting of a pure debt interest until conversion, after which the investment becomes an equity interest. If the security is issued at a premium (i.e., for cash in excess of the face amount payable on retirement), the creditor-holder may amortize the premium over the life of the bond. If the security is issued for cash at a price below its face amount, the creditor-holder must accrue original issue discount in income over the life of the debt. The creditor-holder's exercise of the conversion privilege is treated as a nontaxable event. Mandatorily convertible debt (e.g., an exchange traded note or ETN issued in the form of an unsecured obligation that pays a return based on the performance of a specified market index, exchange currency, or commodity) is often, but not always, treated as a contract to buy or sell the reference property rather than debt. Similarly, convertible preferred stock with a mandatory conversion feature is ordinarily, but not always, treated as equity rather than debt. Dividends received generally are qualified dividend income and eligible for the corporate dividends received deduction. In general, conversion of preferred stock for common stock of the same corporation is tax-free. Conversion of preferred stock for cash is a taxable redemption. Any redemption premium for preferred stock that is redeemable by the issuing company might be required to be amortized under original issue discount ("OID") principles.

Investments in securities of uncertain tax character—A fund may invest in securities the US federal income tax treatment of which may not be clear or may be subject to recharacterization by the IRS. To the extent the tax treatment of such securities or the income from such securities differs from the tax treatment expected by a fund, it could affect the timing or character of income recognized by the fund, requiring the fund to purchase or sell securities, or otherwise change its portfolio, in order to comply with the tax rules applicable to regulated investment companies under the Code.

Backup withholding

By law, the Fund may be required to withhold a portion of your taxable dividends and sales proceeds unless you:

•  provide your correct social security or taxpayer identification number;

•  certify that this number is correct;

•  certify that you are not subject to backup withholdin;, and

•  certify that you are a US person (including a US resident alien).

The Fund also must withhold if the IRS instructs it to do so. When withholding is required, the amount will be 28% of any distributions or proceeds paid. This rate will expire and the backup withholding rate will be

72

31% for amounts paid on or after January 1, 2013, unless the 28% rate is extended, possibly retroactively to January 1, 2013, or made permanent. Backup withholding is not an additional tax. Any amounts withheld may be credited against the shareholder's US federal income tax liability, provided the appropriate information is furnished to the IRS. Certain payees and payments are exempt from backup withholding and information reporting. The special US tax certification requirements applicable to non-US investors to avoid backup withholding are described under the "Non-US investors" heading below.

Non-US investors

Non-US investors (shareholders who, as to the United States, are nonresident alien individuals, foreign trusts or estates, foreign corporations, or foreign partnerships) may be subject to US withholding and estate tax and are subject to special US tax certification requirements. Non-US investors should consult their tax advisors about the applicability of US tax withholding and the use of the appropriate forms to certify their status.

In general—The United States imposes a flat 30% withholding tax (or a withholding tax at a lower treaty rate) on US source dividends, including on income dividends paid to you by the Fund. Exemptions from this US withholding tax are provided for capital gain dividends paid by a Fund from its net long-term capital gains and, with respect to taxable years of a Fund beginning before January 1, 2012 (unless such provision is extended, possibly retroactively to January 1, 2012, or made permanent), interest-related dividends paid by the Fund from its qualified net interest income from US sources and short-term capital gain dividends. However, the Fund does not intend to account for or designate interest-related dividends or short-term capital gains dividends for the benefit of non-US investors. As a result, non-US investors may be subject to more US withholding tax than would otherwise be the case. Notwithstanding such exemptions from US withholding at the source, any dividends and distributions of income and capital gains, including the proceeds from the sale of your Fund shares, will be subject to backup withholding at a rate of 28% (subject to increase as described above) if you fail to properly certify that you are not a US person.

Capital gain dividends—In general, a capital gain dividend reported by the Fund to shareholders as paid from its net long-term capital gains, other than long-term capital gains realized on disposition of US real property interests (see the discussion below) is not subject to US withholding tax unless you are a nonresident alien individual present in the United States for a period or periods aggregating 183 days or more during the calendar year.

Net investment income from dividends on stock and foreign source interest income continue to be subject to withholding tax; foreign tax credits. Ordinary dividends paid by the Fund to non-US investors on the income earned on portfolio investments in (i) the stock of domestic and foreign corporations and (ii) the debt of foreign issuers continue to be subject to US withholding tax. Foreign shareholders may be subject to US withholding tax at a rate of 30% on the income resulting from an election to pass-through foreign tax credits to shareholders, but may not be able to claim a credit or deduction with respect to the withholding tax for the foreign tax treated as having been paid by them.

Income effectively connected with a US trade or business—If the income from the Fund is effectively connected with a US trade or business carried on by a foreign shareholder, then ordinary income dividends, capital gain dividends and any gains realized upon the sale or redemption of shares of the Fund will be subject to US federal income tax at the rates applicable to US citizens or domestic corporations and require the filing of a nonresident US income tax return.

Investment in US real property—The Fund may invest in equity securities of corporations that invest in US real property, including US REITs. The sale of a US real property interest ("USRPI") by the Fund or by a US REIT or

73

US real property holding corporation in which the Fund invests may trigger special tax consequences to the Fund's non-US shareholders.

The Foreign Investment in Real Property Tax Act of 1980 ("FIRPTA") makes non-US persons subject to US tax on disposition of a USRPI as if he or she were a US person. Such gain is sometimes referred to as FIRPTA gain. The Code provides a look-through rule for distributions of FIRPTA gain by a RIC received from a US REIT or another RIC classified as a US real property holding corporation or realized by the RIC on a sale of a USRPI (other than a domestically controlled US REIT or RIC that is classified as a qualified investment entity) as follows:

•  The RIC is classified as a qualified investment entity. A RIC is classified as a "qualified investment entity" with respect to a distribution to a non-US person which is attributable directly or indirectly to a distribution from a US REIT if, in general, 50% or more of the RIC's assets consists of interests in US REITs and US real property holding corporations, and

•  You are a non-US shareholder that owns more than 5% of a class of Fund shares at any time during the one-year period ending on the date of the distribution.

•  If these conditions are met, such Fund distributions to you are treated as gain from the disposition of a USRPI, causing the distributions to be subject to US withholding tax at a rate of 35% (unless reduced by future regulations), and requiring that you file a nonresident US income tax return.

•  In addition, even if you do not own more than 5% of a class of Fund shares, but the Fund is a qualified investment entity, such Fund distributions to you will be taxable as ordinary dividends (rather than as a capital gain or short-term capital gain dividend) subject to withholding at 30% or lower treaty rate.

These rules apply to dividends paid by the Fund before January 1, 2012 (unless such provision is extended, possibly retroactively to January 1, 2012, or made permanent). After such sunset date, Fund distributions from a US REIT (whether or not domestically controlled) attributable to FIRPTA gain will continue to be subject to the withholding rules described above provided the Fund would otherwise be classified as a qualified investment entity.

Because the Fund expects to invest less than 50% of its assets at all times, directly or indirectly, in US real property interests, the Fund expects that neither gain on the sale or redemption of Fund shares nor Fund dividends and distributions would be subject to FIRPTA reporting and tax withholding.

US estate tax—Transfers by gift of shares of the Fund by a foreign shareholder who is a nonresident alien individual will not be subject to US federal gift tax. An individual who, at the time of death, is a non-US shareholder will nevertheless be subject to US federal estate tax with respect to Fund shares at the graduated rates applicable to US citizens and residents, unless a treaty exemption applies. If a treaty exemption is available, a decedent's estate may nonetheless need to file a US estate tax return to claim the exemption in order to obtain a US federal transfer certificate. The transfer certificate will identify the property (i.e., Fund shares) as to which the US federal estate tax lien has been released. In the absence of a treaty, there is a $13,000 statutory estate tax credit (equivalent to US situs assets with a value of $60,000). For estates with US situs assets of not more than $60,000, the Fund may accept, in lieu of a transfer certificate, an affidavit from an appropriate individual evidencing that decedent's US situs assets are below this threshold amount. In addition, a partial exemption from U.S estate tax may apply to Fund shares held by the estate of a nonresident decedent. The amount treated as exempt is based upon the proportion of the assets held by the Fund at the end of the quarter immediately preceding the decedent's death that are

74

debt obligations, deposits, or other property that generally would be treated as situated outside the United States if held directly by the estate. This partial exemption applies to decedents dying after December 31, 2004 and before January 1, 2012, unless such provision is extended, possibly retroactively to January 1, 2012, or made permanent.

US tax certification rules—Special US tax certification requirements may apply to non-US shareholders both to avoid US backup withholding imposed at a rate of 28% (subject to increase to 31% as described above) and to obtain the benefits of any treaty between the United States and the shareholder's country of residence. In general, a non-US shareholder must provide a Form W-8 BEN (or other applicable Form W-8) to establish that you are not a US person, to claim that you are the beneficial owner of the income and, if applicable, to claim a reduced rate of, or exemption from, withholding as a resident of a country with which the United States has an income tax treaty. A Form W-8 BEN provided without a US taxpayer identification number will remain in effect for a period beginning on the date signed and ending on the last day of the third succeeding calendar year unless an earlier change of circumstances makes the information on the form incorrect. Certain payees and payments are exempt from backup withholding.

The tax consequences to a non-US shareholder entitled to claim the benefits of an applicable tax treaty may be different from those described herein. Non-US shareholders are urged to consult their own tax advisors with respect to the particular tax consequences to them of an investment in a Fund, including the applicability of foreign tax.

Foreign Account Tax Compliance Act ("FATCA"). Under the Foreign Account Tax Compliance Act, the relevant withholding agent may be required to withhold 30% of: (a) income dividends paid after December 31, 2013 and (b) certain capital gains distributions and the proceeds of a sale of shares paid after December 31, 2014 to (i) a foreign financial institution ("FFI") unless the FFI becomes a "participating FFI" by entering into a US tax compliance agreement with the IRS under section 1471(b) of the Code ("FFI agreement") and thereby agrees to verify, report and disclose certain of its US accountholders and meets certain other specified requirements or (ii) a non-financial foreign entity that is the beneficial owner of the payment unless such entity certifies that it does not have any substantial US owners or provides the name, address and taxpayer identification number of each substantial US owner and such entity meets certain other specified requirements. These requirements are different from, and in addition to, the US tax certification rules described above. The scope of these requirements remains unclear, and shareholders are urged to consult their tax advisors regarding the application of these requirements to their own situation.

Alternatively, the US Treasury is in various stages of negotiations with a number of foreign governments with respect to one or more other approaches to implement FATCA. Under one proposed model agreement, FFIs located in a foreign country that enters into an intergovernmental agreement with the US Treasury would be required to report US-owned account information directly to their local tax authority, rather than to the IRS. The local tax authority would then automatically share that information with the IRS. Under another approach, FFIs located in a foreign country that enters into an intergovernmental agreement would not need to enter into a separate FFI Agreement with the IRS, provided each FFI registers with the IRS. Under this approach, the FFIs would be required to report US-owned account information directly to the IRS as opposed to reporting via the local tax authority.

Effect of future legislation; local tax considerations

The foregoing general discussion of US federal income tax consequences is based on the Code and the regulations issued thereunder as in effect on the date of this SAI. Future legislative or administrative changes, including provisions of current law that sunset and thereafter no longer apply, or court decisions may significantly change the conclusions expressed herein, and any such changes or decisions may have a

75

retroactive effect with respect to the transactions contemplated herein. Rules of state and local taxation of ordinary income, qualified dividend income and capital gain dividends may differ from the rules for US federal income taxation described above. Distributions may also be subject to additional state, local and foreign taxes depending on each shareholder's particular situation. Non-US shareholders may be subject to US tax rules that differ significantly from those summarized above. Shareholders are urged to consult their tax advisors as to the consequences of these and other state and local tax rules affecting investment in the Fund.

Potential conflicts of interest

Activities of UBS Global Asset Management (Americas) Inc. and its affiliates (collectively, "UBS Global AM"), UBS Securities LLC and UBS Financial Services Inc. and their affiliates (collectively, "UBS") and other accounts managed by UBS

UBS Global AM is a large asset management firm with approximately $625 billion in assets under management worldwide as of September 30, 2012.¹ UBS Global AM offers investment capabilities and investment styles across all major traditional and alternative asset classes, including equity, fixed income, currency, hedge fund, real estate, infrastructure and private equity investment capabilities that can also be combined in multi-asset strategies. UBS Global AM has around 3,800 employees located in 24 countries. UBS Global Asset Management is headquartered in London with other main offices in Chicago, Frankfurt, Hartford, Hong Kong, New York, Paris, Sydney, Tokyo, Toronto and Zurich.

UBS is a worldwide full-service investment banking, broker-dealer, asset management and financial services organization. As a result, UBS Global AM and UBS (including, for these purposes, their directors, partners, officers and employees) worldwide, including the entities and personnel who may be involved in the investment activities and business operations of the Fund, are engaged in businesses and have interests other than that of managing the Fund. These activities and interests include potential multiple advisory, transactional, financial, consultative, and other interests in transactions, companies, securities and other instruments that may be engaged in, purchased or sold by the Fund. This section sets forth considerations of which investors in the Fund should be aware, and which may cause conflicts of interest on the part of UBS and UBS Global AM that could disadvantage the Fund. To address these potential conflicts, UBS and UBS Global AM have established various policies and procedures that are reasonably designed to detect and prevent these potential conflicts of interest and prevent the Fund from being disadvantaged.

Prospective investors should carefully review the following, which more fully describes these and other potential conflicts of interest presented by UBS Global AM and UBS' other businesses and interests.

Potential conflicts relating to portfolio decisions, the sale of Fund shares and the allocation of investment opportunities

UBS' other activities may have an impact on the Fund. UBS Global AM (Americas) makes decisions for the Fund in accordance with its obligations as investment advisor to the Fund. However, UBS' other activities may, at the same time have a negative impact on the Fund. As a result of the various activities and interests of UBS, it is likely that the Fund will have multiple business relationships with, engage in transactions with, make voting decisions with respect to, or obtain services from UBS and other entities for which UBS performs

¹  UBS Global Asset Management (Americas) Inc. manages approximately $152 billion as of September 30, 2012.

76

or seeks to perform investment banking or other services. It is also likely that the Fund will undertake transactions in securities in which UBS makes a market or otherwise has other direct or indirect interests.

UBS conducts extensive broker-dealer, banking and other activities around the world and provides investment banking, broker-dealer, prime brokerage, administrative and other services to clients which may involve markets and securities in which the Fund invests. These activities will give UBS broad access to the current status of certain markets and investments. As a result of the activities described in this paragraph and the access and knowledge arising from those activities, parts of UBS may be in possession of information in respect of markets and investments, which, if known to UBS Global AM (Americas), might cause UBS Global AM (Americas) to seek to dispose of, retain or increase interests in investments held by the Fund or acquire certain positions on behalf of the Fund. UBS will be under no duty to make any such information available to the Fund or personnel of UBS Global AM (Americas) making investment decisions on behalf of the Fund and maintains information barriers designed to prevent the misuse of such information. In general, personnel of UBS Global AM (Americas) making investment decisions will make decisions based solely upon information known by such decision makers without regard to information known by other UBS personnel.

In conformance with the Fund's investment objective and subject to compliance with applicable law, UBS Global AM (Americas) may purchase securities for the Fund during an underwriting or other offering of securities in which a broker-dealer affiliate acts as a manager, co-manager, underwriter or placement agent, or receives a benefit in the form of management, underwriting, or other fees. Affiliates of UBS Global AM (Americas) may act in other capacities in such offerings for which a fee, compensation, or other benefit will be received. From time to time, affiliates of UBS Global AM (Americas) will be current investors in companies engaged in an offering of securities which UBS Global AM (Americas) may purchase on behalf of its clients. Such purchases may provide a direct or indirect benefit to UBS Global AM's affiliates acting as a selling shareholder. UBS Global AM may also participate in structured fixed income offerings of securities in which a related person may serve as trustee, depositor, originator service agent or other service provider in which fees will be paid to such related person. Further, a related person may act as originator and/or servicing agent of loans or receivables for a structured fixed income offering in which UBS Global AM (Americas) may invest Fund assets. Participation in such offering may directly or indirectly relieve financial obligations of related persons.

UBS Global AM may purchase or sell, or recommend for purchase or sale, for its investment advisory clients securities of companies: (i) with respect to which its affiliates act as an investment banker or financial advisor; (ii) with which its affiliates have other confidential relationships; (iii) in which its affiliates maintain a position or (iv) for which its affiliates make a market; or in which it or its officers, directors or employees or those of its affiliates own securities or otherwise have an interest. Except to the extent prohibited by law or regulation or by client instruction, UBS Global AM may recommend to its clients, or purchase for its clients, securities of issuers in which UBS has an interest as described in this paragraph.

UBS' financial and other interests and relationships may incentivize UBS to promote the sale of Fund shares. UBS, its personnel and other financial service providers, have interests in promoting sales of the Fund. UBS Global AM may also make cash and non-cash payments to banks, broker-dealers, insurance companies, financial planning firms and other financial intermediaries, that sell shares of the Fund, subject to UBS Global AM's internal policies and procedures. The source of such payments may come from sales charges on such shares, 12b-1 fees collected from the Fund and/or from the underwriter's own resources (including through transfers from affiliates). Payments made out of the underwriter's own resources are often referred to as "revenue sharing." Please read the section entitled "Principal underwriting arrangements" for more information.

77

With respect to both UBS and its personnel, the remuneration and profitability relating to services to and sales of the Fund or other products may be greater than the remuneration and profitability relating to services to and sales of other products that might be provided or offered by UBS or other third parties. UBS and its sales personnel may directly or indirectly receive a portion of the fees and commissions charged to the Fund or its shareholders. UBS and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions charged to the Fund may also be higher than for other products or services, and the remuneration and profitability to UBS and such personnel resulting from transactions on behalf of or management of the Fund may be greater than the remuneration and profitability resulting from similar transactions for other funds or products.

UBS also may have relationships with, and purchase, or distribute or sell, services or products from or to, distributors, consultants and others who recommend the Fund, or who engage in transactions with or for the Fund. For example, UBS regularly participates in industry and consultant sponsored conferences and may purchase educational, data or other services from consultants or other third parties that it deems to be of value to its personnel and its business. The products and services purchased from consultants may include, but are not limited to, those that help UBS understand the consultant's points of view on the investment management process. Consultants and other parties that provide consulting or other services to potential investors in the Fund may receive fees from UBS or the Fund in connection with the distribution of shares in the Fund or other UBS products. For example, UBS may enter into revenue or fee sharing arrangements with consultants, service providers, and other intermediaries relating to investments in mutual funds, collective trusts, or other products or services offered or managed by UBS Global AM. UBS may also pay a fee for membership in industry-wide or state and municipal organizations or otherwise help sponsor conferences and educational forums for investment industry participants including, but not limited to, trustees, fiduciaries, consultants, administrators, state and municipal personnel and other clients. UBS' membership in such organizations allows UBS to participate in these conferences and educational forums and helps UBS interact with conference participants and to develop an understanding of the points of view and challenges of the conference participants. In addition, UBS' personnel, including employees of UBS, may have board, advisory, brokerage or other relationships with issuers, distributors, consultants and others that may have investments in the Fund or that may recommend investments in the Fund. In addition, UBS, including UBS Global AM, may make charitable contributions to institutions, including those that have relationships with clients or personnel of clients. UBS' personnel may also make political contributions. As a result of the relationships and arrangements described in this paragraph, consultants, distributors and other parties may have conflicts associated with their promotion of the Fund or other dealings with the Fund that create incentives for them to promote the Fund or certain portfolio transactions.

To the extent permitted by applicable law, UBS Global AM may make payments to authorized dealers and other financial intermediaries ("Intermediaries") from time to time to promote the Fund. The additional payments by UBS Global AM may also compensate Intermediaries for subaccounting, administrative and/or shareholder processing services that are in addition to the fees paid for these or similar services by such products. Payments made by UBS Global AM may vary between different Intermediaries. Please read the section entitled "Principal underwriting arrangements" and "Reduced sales charges, additional purchase, exchange and redemption information and other services—Additional compensation to affiliated dealer" for more information.

Potential conflicts relating to the allocation of investment opportunities among the Fund and other UBS accounts. UBS Global AM manages accounts of certain clients by means of separate accounts ("Separate Accounts"). With respect to the Fund, UBS Global AM (Americas) may follow a strategy that is expected to be similar over time to that delivered by the Separate Accounts. The Fund and each of the Separate Account Clients are subject to independent management and, given the independence in the implementation of advice to these accounts, there can be no assurance that such investment advice will be

78

implemented simultaneously. While each will use reasonable endeavors to procure timely execution, it is possible that prior execution for or on behalf of the Separate Accounts could adversely affect the prices and availability of the securities, currencies and instruments in which the Fund invests.

Other potential conflicts relating to the management of the Fund by UBS Global AM

Potential restrictions and issues relating to information held by UBS. From time to time and subject to UBS Global AM's policies and procedures regarding information barriers, UBS Global AM may consult with personnel in other areas of UBS, or with persons unaffiliated with UBS. The performance by such persons of obligations related to their consultation with personnel of UBS Global AM could conflict with their areas of primary responsibility within UBS or elsewhere. There will be no obligation on the part of such persons to make available for use by the Fund any information or strategies known to them or developed in connection with their own client, proprietary or other activities. In addition, UBS will be under no obligation to make available any research or analysis prior to its public dissemination.

In connection with its management of the Fund, UBS Global AM may have access to certain fundamental analysis and proprietary technical models developed by UBS Global AM or its affiliates (including UBS). UBS Global AM will not be under any obligation, however, to effect transactions on behalf of the Fund in accordance with such analysis and models. In addition, neither UBS Global AM nor any of its affiliates (including UBS) will have any obligation to make available any information regarding their proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for the benefit of the management of the Fund and it is not anticipated that UBS Global AM will have access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of UBS Global AM and its affiliates (including UBS) or the activities or strategies used for accounts managed by them or other client accounts could conflict with the transactions and strategies employed by UBS Global AM (Americas), and have adverse effects on the Fund.

Potential conflicts relating to UBS' and UBS Global AM's proprietary activities and activities on behalf of other accounts. Transactions undertaken by UBS or client accounts managed by UBS ("Client Accounts") may adversely impact the Fund. UBS and one or more Client Accounts may buy or sell positions while the Fund is undertaking the same or a differing, including potentially opposite, strategy, which could disadvantage the Fund. For example, the Fund may establish a short position in a security and UBS or other Client Accounts may buy that same security. The subsequent purchase may result in an increase of the price of the underlying position in the short sale exposure of the Fund and such increase in price would be to the Fund's detriment. Conversely, the Fund may buy a security and UBS or Client Accounts may establish a short position in that same security. The subsequent short sale may result in impairment of the price of the security which the Fund holds. Conflicts may also arise because portfolio decisions regarding the Fund may benefit UBS or other Client Accounts. For example, the sale of a long position or establishment of a short position by the Fund may impair the price of the same security sold short by (and therefore benefit) UBS or other Client Accounts, and the purchase of a security or covering of a short position in a security by the Fund may increase the price of the same security held by (and therefore benefit) UBS or other Client Accounts.

The directors, officers and employees of UBS and UBS Global AM may buy and sell securities or other investments for their own accounts or for seed capital accounts (including through investment funds managed by UBS and UBS Global AM). As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers and employees that are the same, different from or made at different times than positions taken for the Fund. To reduce the possibility that the Fund will be materially adversely affected by the personal or proprietary trading described above, the Fund, UBS and UBS Global AM, has established policies and procedures that restrict securities trading in the personal accounts of investment

79

professionals and others who normally come into possession of information regarding the Fund's portfolio transactions. Please see the section entitled "Personal trading policies" for more detailed information regarding these policies and procedures.

UBS Global Asset Management's affiliates have direct or indirect interests in electronic communication networks and alternative trading systems (collectively "ECNs"). UBS Global Asset Management, in accordance with its fiduciary obligation to seek to obtain best execution, may execute client trades through ECNs in which our related persons have, or may acquire, an interest. A related person may receive compensation based upon its ownership percentage in relation to the transaction fees charged by the ECNs. UBS Global Asset Management will execute through an ECN in which a related person has an interest only in situations where we reasonably believe such transactions will be in the best interests of our clients and the requirements of applicable law have been satisfied.

In accordance with Section 11(a) of the Securities Exchange Act of 1934, as amended, and the rules thereunder, UBS Global Asset Management's affiliates may effect transactions for the Fund or advisory client accounts on a national securities exchange of which an affiliate is an equity owner and/or a member and may retain compensation in connection with those transactions.

Gifts and entertainment. From time to time, directors, officers and employees of UBS and UBS Global AM may receive gifts and/or entertainment from clients, intermediaries, or service providers to the Fund, UBS and UBS Global AM, which could have the appearance of affecting or may potentially affect the judgment of the directors, officers and employees or the manner in which they conduct business on behalf of the Fund, UBS and UBS Global AM. To reduce the appearance of impropriety and the possibility that the Fund may be materially adversely affected by such gifts and entertainment, UBS and UBS Global AM have established policies and procedures that restrict the receipt of gifts and entertainment from clients, intermediaries, or service providers to the Fund.

UBS may in-source or outsource. Subject to applicable law, UBS, including UBS Global AM, may from time to time and without notice to investors in-source or outsource certain processes or functions in connection with a variety of services that it provides to the Fund in its administrative or other capacities. Such in-sourcing or outsourcing may give rise to additional conflicts of interest.

Selection of brokers and dealers and commission rates

UBS Global Asset Management utilizes a common portfolio and trading platform for its clients. Certain investment professionals and other employees of UBS Global AM are officers of advisory affiliates and related persons and may provide investment advisory services to clients of such affiliated entities. UBS Global AM's personnel also provide research and trading support to personnel of certain advisory affiliates. Research-related costs may be shared by advisory affiliates and related persons and may benefit the clients of such advisory affiliates. Since research services are shared between UBS Global AM and its advisory affiliates, UBS Global AM and its advisory affiliates maintain an aggregated soft dollar budget. Therefore, research services that benefit UBS Global AM's clients may be paid for with commissions generated by clients of its advisory affiliates. Similarly, research services paid for by commissions generated by UBS Global AM's clients may benefit advisory affiliates and their clients. UBS Global AM does not allocate the relative costs or benefits of research received from brokers or dealers among its clients because UBS Global AM believes that the research received is, in the aggregate, of assistance in fulfilling UBS Global AM's overall responsibilities to its clients. The research may be used in connection with the management of accounts other than those for which trades are executed by the brokers or dealers providing the research. For example, equity research may be used for fixed income funds and accounts.

80

While we select brokers primarily on the basis of the execution capabilities, UBS Global Asset Management, in its discretion, may cause a client to pay a commission to brokers or dealers for effecting a transaction for that client in excess of the amount another broker or dealer would have charged for effecting that transaction. This may be done when we have determined in good faith that the commission is reasonable in relation to the value of the execution, brokerage and/or research services provided by the broker. Our arrangements for the receipt of research services from brokers may create conflicts of interest, in that we have an incentive to choose a broker or dealer that provides research services, instead of one that charges a lower commission rate but does not provide any research.

UBS Global Asset Management and our advisory affiliates utilize a common portfolio and trading platform for our clients. Certain investment professionals and other employees are officers of advisory affiliates and related persons and may provide investment advisory services to clients of such affiliated entities. UBS Global Asset Management's personnel also provide research and trading support to personnel of certain advisory affiliates. Research-related costs may be shared by advisory affiliates and related persons and may benefit the clients of such advisory affiliates. Since research services are shared between UBS Global Asset Management and our advisory affiliates, we maintain an aggregated soft dollar budget. Therefore, research services that benefit our clients may be paid for with commissions generated by clients of our advisory affiliates. Similarly, research services paid for by commissions generated by our clients may benefit advisory affiliates and their clients.

UBS Global Asset Management does not allocate the relative costs or benefits of research received from brokers or dealers among clients because we believe that the research received is, in the aggregate, of assistance in fulfilling our overall responsibilities to clients. The research may be used in connection with the management of accounts other than those for which trades are executed by the brokers or dealers providing the research. UBS Global Asset Management may receive a variety of research services and information on many topics, which we can use in connection with our management responsibilities with respect to the various accounts over which we exercise investment discretion or otherwise provide investment advice. These topics include: issuers, industries, securities, economic factors and trends, portfolio strategy, the performance of accounts, statistical information, market data, earnings estimates, credit analysis, pricing, risk measurement analysis, and other information that may affect the U.S. or foreign economies, security prices, or management of the portfolio.

The research services may include written reports, pricing and appraisal services, market data services, analysis of issues raised in proxy statements, educational seminars, subscriptions to trade journals, portfolio attribution and monitoring services and computer software and access charges which are directly related to investment research. Research services may be received in the form of written reports, online services, telephone contacts and personal meetings with security analysts, economists, corporate and industry spokespersons, investment consultants and government representatives. Research services are either provided directly by broker-dealers or generated by third parties and are provided by the brokerage firm to which the commissions are paid including commission sharing arrangements.

Certain services may be mixed use, or used for research purposes as well as other purposes. Payment for these services is made as follows: the portion allocated to research is paid for through commissions, and the portion allocated to other purposes is paid for by UBS Global Asset Management. This allocation is determined by our Best Execution and Trading Committee in good faith and based on objective criteria, to the extent available, of the amounts used for research and non-research purposes; however, the decision regarding what amounts are paid by UBS Global Asset Management versus paid by clients through commissions presents a conflict of interest. Research services received from brokers and dealers may be supplemental to our own research efforts and, when utilized, are subject to internal analysis before being incorporated into our investment process. As a practical matter, it would not be possible UBS Global Asset Management to generate all of the information presently provided by brokers and dealers.

81

UBS Global Asset Management may receive in-house or proprietary research from dealers that execute trades on a principal basis for our clients. The research received will be of the type described above, excluding third-party research services.

Potential regulatory restrictions on investment advisor activity

From time to time, the activities of the Fund may be restricted because of regulatory requirements applicable to UBS and/or its internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by UBS would not be subject to some of those considerations. There may be periods when UBS Global AM may not initiate or recommend certain types of transactions, or may otherwise restrict or limit its advice with respect to certain securities or instruments issued by or related to companies for which UBS is performing investment banking, market making or other services or has proprietary positions or otherwise has come into possession of material inside information. For example, when UBS is engaged in an underwriting or other distribution of securities of, or advisory services for, a company, the Fund may be prohibited from or limited in purchasing or selling securities of that company. Similar situations could arise if UBS personnel serve as directors of companies the securities of which the Fund wishes to purchase or sell. The larger UBS Global AM's investment advisory business and UBS' businesses, the larger the potential that these restricted list policies will impact investment transactions. However, if permitted by applicable law, the Fund may purchase securities or instruments that are issued by such companies or are the subject of an underwriting, distribution, or advisory assignment by UBS, or in cases in which UBS personnel are directors or officers of the issuer.

The investment activities of UBS for its proprietary accounts and for Client Accounts may also limit the investment strategies and rights of the Fund. For example, in regulated industries, in certain emerging or international markets, in corporate and regulatory ownership definitions, and in certain futures and derivative transactions, there may be limits on the aggregate amount of investment by affiliated investors that may not be exceeded without the grant of a license or other regulatory or corporate consent or, if exceeded, may cause UBS, the Fund or other Client Accounts to suffer disadvantages or business restrictions. If certain aggregate ownership thresholds are reached or certain transactions undertaken, the ability of UBS Global AM on behalf of the Fund to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. As a result, UBS Global AM on behalf of the Fund may limit purchases, sell existing investments, or otherwise restrict or limit the exercise of rights (including voting rights) when UBS Global AM, in its sole discretion, deems it appropriate.

UBS Global AM and its affiliates, including, without limitation, UBS and its advisory affiliates, have proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts, other funds and collective investment vehicles) that have investment objectives similar to those of the Fund and/or that engage in transactions in the same types of securities, currencies and instruments as the Fund. UBS and its affiliates are also major participants in the global currency, equities, swap and fixed income markets, in each case both on a proprietary basis and for the accounts of customers. As such, UBS and its affiliates may be actively engaged in transactions in the same securities, currencies, and instruments in which the Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which the Fund invests, which could have an adverse impact on the Fund's performance. Such transactions, particularly in respect of most proprietary accounts or client accounts, will be executed independently of the Fund's transactions and thus at prices or rates that may be more or less favorable than those obtained by the Fund. UBS Global AM has developed policies and procedures consistent with regulatory requirements that provide that it will allocate investment opportunities and make purchase and sale decisions among the Fund and other client accounts in a manner that it considers, in its sole discretion and consistent with its fiduciary obligation to each account, to be reasonable. Allocations may be based on numerous factors and may not

82

always be pro rata based. Thus, this system may adversely affect the size or price of the assets purchased or sold for the Fund.

The results of the Fund's investment activities may differ significantly from the results achieved by UBS Global AM and its affiliates for their proprietary accounts or other accounts (including investment companies or collective investment vehicles) managed or advised by them. It is possible that UBS Global AM and its affiliates and such other accounts will achieve investment results that are substantially more or less favorable than the results achieved by the Fund. Moreover, it is possible that the Fund will sustain losses during periods in which UBS Global AM and its affiliates achieve significant profits on their trading for proprietary or other accounts. The opposite result is also possible.

The investment activities of UBS Global AM and its affiliates for their proprietary accounts and accounts under their management may also limit the investment opportunities for the Fund in certain emerging and other markets in which limitations are imposed upon the amount of investment, in the aggregate or in individual issuers, by affiliated foreign investors.

From time to time, the Fund's activities may also be restricted because of regulatory restrictions applicable to UBS Global AM and its affiliates, and/or their internal policies designed to comply with such restrictions. As a result, there may be periods, for example, when UBS Global AM, and/or its affiliates, will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which UBS Global AM and/or its affiliates are performing services or when position limits have been reached where such securities or instruments otherwise would have been permissible investments for the Fund. Additionally, the Fund or certain accounts may be licensed to trade securities or engage in transactions in certain jurisdictions while other series of the Trust and accounts are not licensed.

In addition, certain officers and certain employees of UBS Global AM are also officers or employees of UBS, or its affiliated entities. As a result, the performance by these officers and employees of their obligations to such other entities may be a consideration of which investors in the Fund should be aware.

UBS Global AM may enter into transactions and invest in securities, instruments and currencies on behalf of the Fund where customers of UBS or, to the extent permitted by the SEC, UBS itself, serves as the counterparty, principal or issuer. In such cases, such party's interests in the transaction will be adverse to the interests of the Fund, and such party may have no incentive to assure that the Fund obtains the best possible prices or terms in connection with the transaction. In addition, the purchase, holding and sale of such investments by the Fund may enhance the profitability of UBS Global AM and/or UBS. UBS and its affiliates may also create, write or issue Derivatives for customers of UBS or its affiliates, the underlying securities, currencies or instruments of which may be those in which the Fund invests or which may be based on the performance of the Fund. The Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by UBS or its affiliates and may also enter into transactions with other clients of UBS Global AM or its affiliates where such other clients have interests adverse to those of the Fund. At times, these activities may cause UBS Global AM or its affiliates to give advice to clients that may cause these clients to take actions adverse to the interests of the Fund. To the extent affiliated transactions are permitted, the Fund will deal with UBS Global AM, UBS and its affiliates on an arms-length basis. UBS Global AM or UBS may also have an ownership interest in certain trading or information systems used by the Fund. The Fund's use of such trading or information systems may enhance the profitability of UBS Global AM and its affiliates.

It is also possible that, from time to time, UBS Global AM or any of its affiliates may, although they are not required to, purchase and hold shares of the Fund. Increasing the Fund's assets may enhance investment

83

flexibility and diversification and may contribute to economies of scale that tend to reduce the Fund's expense ratio. UBS Global AM and its affiliates reserve the right to redeem at any time some or all of the shares of the Fund acquired for their own accounts. A large redemption of shares of the Fund by UBS Global AM or its affiliates could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund's investment flexibility, portfolio diversification, expense ratio and may result in significant transaction costs. UBS Global AM will consider the effect of redemptions on the Fund and other shareholders in deciding whether and when to redeem its shares.

It is possible that the Fund may invest in securities of companies with which UBS has or is trying to develop investment banking relationships as well as securities of entities in which UBS Global AM or UBS has significant debt or equity investments or in which UBS makes a market. The Fund also may invest in securities of companies to which UBS Global AM or UBS provides or may someday provide research coverage. Such investments could cause conflicts between the interests of the Fund and the interests of other UBS Global AM or UBS clients. In making investment decisions for the Fund, UBS Global AM is not permitted to obtain or use material non-public information acquired by any division, department or affiliate of UBS Global AM in the course of these activities. In addition, from time to time, UBS' activities may limit the Fund's flexibility in purchases and sales of securities. When UBS is engaged in an underwriting or other distribution of securities of an entity, UBS Global AM may be prohibited from purchasing or recommending the purchase of certain securities of that entity for the Fund.

Present and future activities of UBS Global AM and its affiliates, in addition to those described in this section, may give rise to additional conflicts of interest.

UBS Global AM (Americas) may buy for the Fund securities or obligations of issuers in which UBS or other funds or accounts have made, or are making, an investment in securities or obligations that are subordinate or senior to securities of the Fund. For example, the Fund may invest in debt securities of an issuer at the same time that UBS or other funds or accounts are investing, or currently have an investment, in equity securities of the same issuer. To the extent that the issuer experiences financial or operational challenges which may impact the price of its securities and its ability to meet its obligations, decisions by UBS (including UBS Global AM (Americas)) relating to what actions to be taken may also raise conflicts of interests and UBS may take actions for certain accounts that have negative impacts on other advisory accounts.

While UBS Global AM (Americas) will make proxy voting decisions as it believes appropriate and in accordance with UBS Global AM's policies designed to help avoid conflicts of interest, proxy voting decisions made by UBS Global AM (Americas) with respect to the Fund's portfolio securities may have the effect of favoring the interests of other clients or businesses of other divisions or units of UBS. UBS Global AM's proxy voting policy is discussed in more detail in the section entitled "Proxy voting policies."

As a registered investment advisor under the Advisers Act, UBS Global AM (Americas) is required to file a Form ADV with the SEC. Form ADV Part 2A contains information about assets under management, types of fee arrangements, types of investments, potential conflicts of interest, and other relevant information regarding UBS Global AM (Americas). A copy of Parts 1A and 2A of UBS Global AM (Americas)'s Form ADV is available on the SEC's website (www.adviserinfo.sec.gov).

Performance calculations

From time to time, performance information, such as yield or total return, may be quoted in advertisements or in communications to present or prospective shareholders. Performance quotations represent the Fund's past performance and should not be considered as representative of future results. The current yield will be calculated by dividing the net investment income earned per share by the Fund during the period stated in the advertisement (based on the average daily number of shares entitled to receive dividends outstanding during the period) by the maximum net asset value per share on the last day of the period and annualizing the result on a semiannual compounded basis. The Fund's total return may be calculated on an annualized and aggregate basis for various periods (which periods will be stated in the advertisement). Average annual return reflects the average percentage change per year in value of an investment in the Fund. Aggregate total return reflects the total percentage change over the stated period.

To help investors better evaluate how an investment in the Fund might satisfy their investment objectives, advertisements regarding the Fund may discuss yield or total return as reported by various financial publications. Advertisements may also compare yield or total return to other investments, indices and averages. The following publications, benchmarks, indices and averages may be used: Lipper Mutual Fund Performance Analysis; Lipper Fixed Income Analysis; Lipper Mutual Fund Indices; Morgan Stanley Capital International Indices; Barclays Indices; Salomon Smith Barney Indices; Dow Jones Composite Average or its component indices; Standard & Poor's 500 Stock Index or its component indices; Russell Indices; Wilshire Indices; The New York Stock Exchange composite or component indices; CDA Mutual Fund Report; Weisenberger-Mutual Funds Panorama and Investment Companies; Mutual Fund Values and Mutual Fund Service Book, published by Morningstar, Inc.; comparable portfolios managed by the Advisor; and financial publications, such as Business Week, Kiplinger's Personal Finance, Financial World, Forbes, Fortune, Money Magazine, The Wall Street Journal, Barron's et al., which rate fund performance over various time periods.

The principal value of an investment in the Fund will fluctuate, so that an investor's shares, when redeemed, may be worth more or less than their original cost. Any fees charged by banks or other institutional investors directly to their customer accounts in connection with investments in shares of the Fund will not be included in the Fund's calculations of yield or total return.

Performance information for the various classes of shares of the Fund will vary due to the effect of expense ratios on the performance calculations.

Financial statements and report of independent registered public accounting firm

The Fund's financial statements for the fiscal year ended June 30, 2012 and the report thereon of Ernst & Young LLP, dated August 29, 2012, which are contained in the Fund's Annual Report dated June 30, 2012 (as filed with the SEC on September 7, 2012, pursuant to Section 30(b) of the Act and Rule 30b2-1 thereunder (Accession Number (0001104659-12-062230)), are incorporated herein by reference.

ITEM 30.INDEMNIFICATION

Under the terms of the Delaware Statutory Trust Act (“DSTA”) and the Registrant’s Amended and Restated Agreement and Declaration of Trust, as amended, (“Declaration of Trust”), no officer or trustee of the Registrant shall have any liability to the Registrant, its shareholders, or any other party for damages, except to the extent such limitation of liability is precluded by Delaware law, the Declaration of Trust or the By-Laws of the Registrant.

Subject to the standards and restrictions set forth in the Declaration of Trust, DSTA, Section 3817, permits a statutory trust to indemnify and hold harmless any trustee, beneficial owner or other person from and against any and all claims and demands whatsoever.  DSTA, Section 3803 protects trustees, officers, managers and other employees, when acting in such capacity, from liability to any person other than the Registrant or beneficial owner for any act, omission or obligation of the Registrant or any trustee thereof, except as otherwise provided in the Declaration of Trust.

Indemnification of the Trustees and officers of the Registrant is provided for in Article VII, Sections 2 through 4 of the Registrant’s Declaration of Trust effective as of September 28, 2004, as amended, as follows:

Section 2. Indemnification and Limitation of Liability. The Trustees shall not be responsible or liable in any event for any neglect or wrong-doing of any officer, agent, employee, Manager or Principal Underwriter of the Trust, nor shall any Trustee be responsible for the act or omission of any other Trustee, and, subject to the provisions of the Bylaws, the Trust out of its assets may indemnify and hold harmless each and every Trustee and officer of the Trust from and against any and all claims, demands, costs, losses, expenses, and damages whatsoever arising out of or related to such Trustee’s performance of his or her duties as a Trustee or officer of the Trust; provided that nothing herein contained shall indemnify, hold harmless or protect any Trustee or officer from or against any liability to the Trust or any Shareholder to which he or she would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office.

Every note, bond, contract, instrument, certificate or undertaking and every other act or thing whatsoever issued, executed or done by or on behalf of the Trust or the Trustees or any of them in connection with the Trust shall be conclusively deemed to have been

Ladies and Gentlemen:

1.             The fund listed on Schedule A hereto (the “Fund”) is a series of The UBS Funds, a Delaware statutory trust (“Trust”).  Each separate class of the Fund’s shares is referred to herein as a “Class.”

2.             You hereby agree that you will waive your advisory fees and/or reimburse the Trust for the operating expenses (excluding expenses incurred through investment in other investment companies, interest, taxes, brokerage commissions, extraordinary expenses, and dividend expense and securities loan fees for securities sold short) (“Reimbursable Operating Expenses”) of the Fund or any Class thereof to the extent, if any, that the Reimbursable Operating Expenses for a Fund or any Class thereof, for the period ending October 28, 2014, otherwise would exceed the “Expense Limitation” rate for each Class of the Fund shown in Schedule B.  The aggregate amount of this waiver/reimbursement is hereinafter referred to as the “Expense Reimbursement.”

3.             The Trust, in turn, agrees that, subject to the limitations set forth in this paragraph, it will repay the Expense Reimbursement to you.  Such repayment shall be made only out of assets of the Fund or Class for which an Expense Reimbursement was made.  In addition, the repayment shall be payable only to the extent it can be made during the three years following the period during which you waived fees or reimbursed the Fund or Class for its Reimbursable Operating Expenses under this Agreement without causing the Reimbursable Operating Expenses of the Fund or Class during a year in which such repayment is made to exceed any applicable expense limit that may be in place for the Fund.  The Trust agrees to furnish or otherwise make available to you such copies of its financial statements, reports, and other information relating to its business and affairs as you may, at any time or from time to time, reasonably request in connection with this Agreement.

4.             This Agreement shall terminate automatically upon the termination of the Investment Advisory Agreement between you and the Trust with respect to the Fund; provided, however, that the Fund’s obligation to reimburse you, as described

above, will survive the termination of this Agreement unless the Trust and you agree otherwise.

5.             You understand that you shall look only to the assets of the Fund for performance of this Agreement and for payment of any claim you may have hereunder, and neither any other series of the Trust, nor any of the Trust’s trustees, officers, employees, agents, or shareholders, whether past, present or future, shall be personally liable therefor.

6.             This Agreement shall be governed by, and construed and enforced in accordance with, the internal laws of the State of New York, except (a) Paragraph 5 shall be governed by, construed and enforced in accordance with the laws of the State of Delaware and (b) insofar as the Investment Company Act of 1940, as amended, or other federal laws and regulations may be controlling.  Any amendment to this Agreement shall be in writing signed by the parties hereto.

If you are in agreement with the foregoing, please sign the form of acceptance on the enclosed counterpart hereof and return the same to us.

Very truly yours,
