The Board has delegated to the UBS Global Asset Management Global Valuation Committee (“GVC”) the responsibility for making fair value determinations with respect to the Fund’s portfolio holdings. The GVC is comprised of representatives of management, including members of the investment team.

The GVC provides reports to the Board at each quarterly meeting regarding any securities or instruments that have been fair valued, valued pursuant to standing instructions approved by the GVC, or where non vendor pricing sources had been used to make fair value determinations when sufficient information exists during the prior quarter. Fair valuation determinations are subject to review at least monthly by the GVC during scheduled meetings. Pricing decisions, processes, and controls over fair value determinations are subject to internal and external reviews, including annual internal compliance reviews, periodic internal audit reviews and annual review of securities valuations by the Fund’s independent auditors.

The types of securities or instruments for which such fair value pricing may be necessary include, but are not limited to: foreign securities and instruments under some circumstances, as discussed below, securities of an issuer that has entered into a restructuring; securities or instruments whose trading has been halted or suspended; fixed income securities that are in default and for which there is no current market value quotation; and securities or instruments that are restricted as to transfer or resale. The need to fair value a Fund’s portfolio securities and other instruments may also result from low trading volume in foreign markets or thinly traded domestic securities or instruments, and when a security is subject to a trading limit or collar on the exchange or market on which it is primarily traded reaches the “limit up” or “limit down” price and no trading has taken place at that price. Various factors may be reviewed in order to make a good faith determination of a security’s or instrument’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 or instruments; and the evaluation of forces which influence the market in which the securities or instruments are purchased and sold. Valuing securities and other instruments at fair value involves greater reliance on judgment than valuing securities and other instruments that have readily available market quotations. Fair value determinations can also involve reliance on quantitative models employed by a fair value pricing service.

US generally accepted accounting principles (“GAAP”) requires disclosure regarding the various inputs that are used in determining the value of the Fund’s investments. These inputs are summarized into the three broad levels listed below:

Level 1 – Unadjusted quoted prices in active markets for identical investments.

Level 2 – Other significant observable inputs, including but not limited to, quoted prices for similar investments, interest rates, prepayment speeds and credit risk.

Level 3 – Unobservable inputs inclusive of the Fund’s own assumptions in determining the value of investments.

In May 2011, FASB issued Accounting Standards Update No. 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in US GAAP and International Financial Reporting Standards” (“IFRS”) (“ASU 2011-04”). ASU 2011-04 includes common requirements for measurement of and disclosure about fair value between US GAAP and IFRS. ASU 2011-04 will require reporting entities to disclose the following information for fair value measurements categorized within Level 3 of the fair value hierarchy: quantitative information about the unobservable inputs used in the fair value measurement, the valuation processes used by the reporting entity and a narrative description of the sensitivity of the fair value measurement to changes in unobservable inputs and the interrelationships between those unobservable inputs. In addition, ASU 2011-04 will require reporting entities to make disclosures about amounts and reasons for all transfers in and out of Level 1 and Level 2 fair value measurements. The new and revised disclosures are effective for interim and annual reporting periods beginning after December 15, 2011. At this time, management is evaluating the implications of ASU 2011-04 and its impact on the financial statements.

The following is a summary of the fair valuations according to the inputs used as of June 30, 2012 in valuing the Fund’s investments:

10   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 and other instruments from independent pricing sources and broker-dealers. Independent pricing sources may use reported last sale prices, official market closing prices, current market quotations or valuations from computerized “evaluation” systems that derive values based on comparable securities or instruments. An evaluation 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 the portfolio securities or instruments. Securities and other instruments also may be valued based on appraisals derived from information concerning the security or instrument or similar securities or instruments received from recognized dealers in those holdings. Securities and instruments 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 on the valuation date available prior to valuation. Securities and instruments which are listed on US and foreign stock exchanges normally are valued at the market closing price, the last sale price on the day the securities are valued or, lacking any sales on such day, at the last available bid price. In cases where securities or instruments are traded on more than one exchange, the securities or instruments are valued on the exchange designated as the primary market by UBS Global Asset Management (Americas) Inc. (“UBS Global AM” or the “Advisor”), the investment advisor of the Fund. If a market value is not readily available from an independent pricing source for a particular security or instrument, that security or instrument 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 or instrument’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 or instruments; and the evaluation of forces which influence the market in which the securities or instruments are purchased and sold. Foreign currency exchange rates are generally determined as of the close of the New York Stock Exchange (“NYSE”). Certain securities or instruments in which the Fund invests are traded in markets that close before 4:00 p.m., Eastern time. Normally, developments that occur between the close of the foreign markets and 4:00 p.m. Eastern Time will not be reflected in the Fund’s net asset value. However, if the Fund determines that such developments are so significant that they will materially affect the value of the Fund’s securities or instruments, the Fund may adjust the previous closing prices to reflect what the Board believes to be the fair value of these securities or instruments as of 4:00 p.m. Eastern Time. The amortized cost method of valuation, which approximates market value, generally is used to value short-term debt instruments with 60 days or less remaining to maturity, unless the Board determines that this does not represent fair value. Investments in open-end investment companies are valued at the daily closing net asset value of the respective investment company. Pursuant to the Fund’s use of the practical expedient within ASC Topic 820, investments in non-registered investment companies are also valued at the daily net asset value. All investments quoted in foreign currencies will be valued daily in US dollars on the basis of the foreign currency exchange rates prevailing at the time such valuation is determined by the Fund’s custodian.
11   Transfers into Level 3 represent the value at the end of the period. At June 30, 2012, a security was transfered from Level 2 to Level 3 as the valuation is based on unobservable inputs.
