1"Weekly liquid assets" is a term defined in US SEC Rule 2a-7 (which governs money market funds) and includes cash, direct obligations of the US government, certain securities issued by US government instrumentalities with a remaining maturity date of 60 days or less, and securities that mature or are subject to a demand feature exercisable and payable within five business days.
"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.
You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The Fund may impose a fee upon sale of your shares or may temporarily suspend your ability to sell shares 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.
