"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 initial investment of $99 million for UBS Select Prime Preferred Funds).

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. You may obtain a prospectus by selecting the "Documents – All Funds" tab on the navigation bar above and clicking the "PDF" link under the column "Prospectus" in the row for that particular fund.

Performance data quoted represent past performance, and the Fund's yield will fluctuate. Past performance does not guarantee future results. Current performance may be lower or higher than the performance data quoted.

Current and future portfolio holdings are subject to risk.

You could lose money by investing in the Fund. Because the price of interests in the Fund will fluctuate, when you sell your interest it may be worth more or less than what you originally paid for it. The Fund may impose a fee upon sale of your interest or may temporarily suspend your ability to sell an interest if the Fund's liquidity falls below required minimums because of market conditions or other factors. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund's sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time.

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