INSTITUTIONAL MONEY MARKET FUNDS *

*"Institutional" funds are available to investors (such as corporations, partnerships, endowments, foundations, government entities and individuals) meeting certain criteria as noted in fund offering documents (e.g. minimum intitial investment of $99 million for UBS Select Prime Preferred Funds).

^** Please click on "PDF" to access a copy of a fund's prospectus (and any related supplements) in "portable document format." Please click on "XBRL" to access the risk/return summary section of the prospectus (and any updated supplements to that section); "XBRL" files are intended for use in applications supporting that format. (The availability of "XBRL" files is being phased in beginning in 2011).

An investment in each Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although each Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in each Fund.

Not FDIC insured. May lose value. No bank guarantee.

Mutual funds are sold by prospectus, which includes more complete information on risks, charges, expenses and other matters of interest. Investors should read the prospectus carefully before investing.
