(7)   The Fund calculates its net asset value based on the current market value, where available, for its portfolio securities. The Fund normally obtains market values for its securities from independent pricing sources. Independent pricing sources may use reported last sale prices, current market quotations or valuations from computerized “matrix” systems that derive values based on comparable securities. A matrix system incorporates parameters such as security quality, maturity and coupon, and/or research and evaluations by its staff, including review of broker-dealer market price quotations, if available, in determining the valuation of portfolio securities. Securities traded in the over-the-counter (“OTC”) market and listed on The NASDAQ Stock Market, Inc. (“NASDAQ”) normally are valued at the NASDAQ Official Closing Price. Other OTC securities are valued at the last bid price available on the valuation date prior to valuation. Securities which are listed on US and foreign stock exchanges normally are valued at the last sale price on the day the securities are valued or, lacking any sales on such day, at the last available bid price. Securities listed on foreign stock exchanges may be fair valued based on significant events that have occurred subsequent to the close of the foreign markets. The Fund may use a systematic fair valuation model provided by an independent third party to value securities principally traded in foreign markets in order to adjust for possible stale pricing that may occur between the close of the foreign exchanges and the time for valuation. If a security is valued at a “fair value,” that value is likely to be different from the last quoted market price for the security. In cases where securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by UBS Global Asset Management (Americas) Inc. (“UBS Global AM”), the investment manager of the Fund. UBS Global AM is an indirect wholly owned asset management subsidiary of UBS AG, an internationally diversified organization with headquarters in Zurich and Basel, Switzerland and operations in many areas of the financial services industry. If a market value is not readily available from an independent pricing source for a particular security, that security is valued at fair value as determined in good faith by or under the direction of the Fund’s Board of Directors (the “Board”). Various factors may be reviewed in order to make a good faith determination of a security’s fair value. These factors include, but are not limited to, fundamental analytical data relating to the investment; the nature and duration of restrictions on disposition of the securities; and the evaluation of forces which influence the market in which the securities are purchased and sold. Investments in open-end investment companies are valued at the daily closing net asset value of the respective investment company.

TIPS   Treasury inflation protected securities (“TIPS”) are debt securities issued by the US Treasury whose principal and/or interest payments are adjusted for inflation, unlike debt securities that make fixed principal and interest payments. The interest rate paid by the TIPS is fixed, while the principal value rises or falls based on changes in a published Consumer Price Index (“CPI”). Thus, if inflation occurs, the principal and interest payments on the TIPS are adjusted accordingly to protect investors from inflationary loss. During a deflationary period, the principal and interest payments decrease, although the TIPS principal amounts will not drop below their face amounts at maturity. In exchange for the inflation protection, the TIPS generally pay lower interest rates than typical US Treasury securities. Only if inflation occurs will TIPS offer a higher real yield than a conventional Treasury bond of the same maturity.
