11 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. Securities and instruments listed on foreign stock exchanges may be fair valued based on significant events that have occurred subsequent to the close of the foreign markets. 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. 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 or instrument, that security or instrument is valued at a fair value 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. 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 are 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.

US Generally accepted accounting principles (“GAAP”) requires disclosure surrounding 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 January 2010, FASB issued Accounting Standards Update (“ASU”) No. 2010-06, “Improving Disclosures about Fair Value Measurements” (“ASU 2010-06”). ASU 2010-06 requires reporting entities to make new disclosures about amounts and reasons for significant transfer in and out of Level 1 and Level 2 fair value measurements as well as inputs and valuation techniques used to measure fair value for both recurring and nonrecurring fair value measurements that fall in either Level 2 or Level 3, including information on purchases, sales, issuances and settlements on a gross basis in the reconciliation of activity in Level 3 fair value measurements. The new and revised disclosures have been implemented for annual and interim periods beginning after December 15, 2009. The disclosures surrounding purchases, sales, issuances and settlements on a gross basis in the reconciliation of Level 3 fair value measurements have been implemented for annual and interim periods beginning after December 15, 2010.

In May 2011, FASB issued Accounting Standards Update No. 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. 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 U.S. 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.
