UBS U.S. Small Cap Equity Fund Summary

Investment objective

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

current income.

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:

Expense Example UBS U.S. SMALL CAP EQUITY FUND (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years
CLASS A	685	1,058
CLASS C	318	766
CLASS Y	117	461

Expense Example, No Redemption (USD $)	Expense Example, No Redemption, 1 Year	Expense Example, No Redemption, 3 Years
UBS U.S. SMALL CAP EQUITY FUND CLASS C	218	766

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.

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 securities of US

small capitalization companies. Small capitalization companies are those

companies with market capitalizations of less than $3 billion. Investments in

equity securities may include, but are not limited to, dividend-paying

securities, common stock and preferred stock. The Fund is a non-diversified

fund.



The Fund may, but is not required to, use 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 on indices, which may

be used for risk management purposes to manage or adjust the risk profile of the

Fund. 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.



Under certain market conditions, the Fund may invest in companies at the time of

their initial public offering ("IPO").



Management process



The Advisor looks for companies with strong and innovative management, good

financial controls, increasing market share, diversified product/service

offerings and low market-to-sales ratios relative to similar companies. In

selecting securities, the Advisor focuses on, among other things, identifying

discrepancies between a security's fundamental value and its market price. In

this context, the fundamental value of a given security is the Advisor's

assessment of what a security is worth. The Fund will select a security whose

fundamental value it estimates to be greater than its market value at any given

time. For each stock under analysis, the Advisor bases its estimates of value

upon economic, industry and company analysis, as well as upon a company's

management team, competitive advantage and core competencies. The Advisor then

compares its assessment of a security's value against the prevailing market

prices with the aim of constructing a portfolio of stocks with attractive

relative price/value characteristics.



The Fund will invest in companies within its capitalization range as described

above. However, the Fund may invest a portion of its assets in securities

outside of this range. Further, if movement in the market price causes a

security to change from one capitalization range to another, the Fund is not

required to dispose of the security.

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.



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.



Management risk: The risk that the investment strategies, techniques and risk

analyses employed by the Advisor may not produce the desired results.



Non-diversification risk: The Fund is a non-diversified investment company,

which means that the Fund may invest more of its assets in a smaller number of

issuers than a diversified investment company. As a non-diversified fund, the

Fund's share price may be more volatile and the Fund has a greater potential to

realize losses upon the occurrence of adverse events affecting a particular

issuer.



IPOs risk: The purchase of shares issued in IPOs may expose the Fund to the

risks associated with issuers that have no operating history as public

companies, as well as to the risks associated with the sectors of the market in

which the issuer operates. The market for IPO shares may be volatile, and share

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

of time.



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 and management risks. 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 (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.

Performance

There is no performance information quoted for the Fund as the Fund had not

commenced investment operations as of the date of this prospectus.

[1] "Other expenses" are based on estimates for the current fiscal year.

[2] 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 and extraordinary expenses) 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 and extraordinary expenses), through the period ending October 27, 2012, do not exceed 1.40% for Class A shares, 2.15% for Class C shares and 1.15% 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.
