Principal strategies

Principal investments



The fund is a money market mutual fund and seeks to maintain a stable price of

$1.00 per share. To do this, the fund invests in a diversified portfolio of high

quality money market instruments of governmental and private issuers.



Money market instruments generally are short-term debt obligations and similar

securities. They also may include longer-term bonds that have variable interest

rates or other special features that give them the financial characteristics of

short-term debt. The fund invests in foreign money market instruments only if

they are denominated in US dollars.



Management process



UBS Global Asset Management (Americas) Inc. ("UBS Global AM"), the fund's

manager and investment advisor, selects money market instruments for the fund

based on its assessment of relative values and changes in market and economic

conditions. UBS Global AM considers safety of principal and liquidity in

selecting securities for the fund and thus may not buy securities that pay the

highest yield.

Principal risks

All investments carry a certain amount of risk and the fund cannot guarantee

that it will achieve its investment objective. While the fund seeks to maintain

the value of your investment at $1.00 per share, you may lose money by investing

in the fund. An investment in the fund is not a bank deposit and is not insured

or guaranteed by the Federal Deposit Insurance Corporation or any other

government agency. Money market instruments generally have a low risk of loss,

but they are not risk-free. The principal risks presented by an investment in

the fund are:



Credit risk: Issuers of money market instruments may fail to make payments when

due, or they may become less willing or less able to do so.



Interest rate risk: The value of the fund's investments generally will fall when

short term interest rates rise, and its yield will tend to lag behind prevailing

rates.



US Government securities risk: There are different types of US government

securities with different levels of credit risk, including the risk of default,

depending on the nature of the particular government support for that security.

For example, a US government-sponsored entity, such as Federal National Mortgage

Association ("Fannie Mae") or Federal Home Loan Mortgage Corporation ("Freddie

Mac"), although chartered or sponsored by an Act of Congress, may issue

securities that are neither insured nor guaranteed by the US Treasury and are

therefore riskier than those that are.



Foreign investing risk: The value of the fund's investments in foreign

securities may fall due to adverse political, social and economic developments

abroad. Investments in foreign government bonds involve special risks because

the fund may have limited legal recourse in the event of default. However,

because the fund's foreign investments must be denominated in US dollars, it

generally is not subject to the risk of changes in currency valuations.



Liquidity risk: Although the fund invests in a diversified portfolio of high

quality instruments, the fund's investments may become less liquid as a result

of market developments or adverse investor perception.



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

analyses employed by the investment advisor may not produce the desired results.

[1] The fund and UBS Global Asset Management (Americas) Inc. ("UBS Global AM") have entered into a written fee waiver/expense reimbursement agreement pursuant to which UBS Global AM is contractually obligated to waive its management fees and/or reimburse expenses so that the fund's ordinary total operating expenses through November 28, 2012 (excluding dividend expense, borrowing costs, and interest expense relating to short sales, and expenses attributable to investment in other investment companies, interest, taxes, brokerage commissions and extraordinary expenses) would not exceed 0.60%. The fund has agreed to repay UBS Global AM for any waived fees/reimbursed expenses to the extent that it can do so over the following three fiscal years without causing the fund's expenses in any of those three years to exceed this expense cap. The fee waiver/expense reimbursement agreement may be terminated by the fund's board at any time and also will terminate automatically upon the expiration or termination of the fund's advisory contract with UBS Global AM. Upon termination of the agreement, however, UBS Global AM's three year recoupment rights will survive.

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