• Effective November 1, 2008, the Fund adopted Financial Accounting Standards Board Statement of Financial Accounting 
           Standards No. 157, "Fair Value Measurements" ("FAS 157"). FAS 157 clarifies the definition of fair value, establishes a 
           framework for measuring fair values and requires additional disclosures about the use of fair value measurements. 
           Various inputs are used in determining the fair value of investments, which are as follows: 
                                       • Level 1 - price quotations in active markets/exchanges for identical securities 
• Level 2 - other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities 
                                           in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not 
                                           active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest 
                                           rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other 
                                           market-corroborated inputs)   
                                       • Level 3 - unobservable inputs based on the best information available in the circumstances, to the extent 
                                           observable inputs are not available (including the Fund's own assumptions used in determining the fair value 
                                           of investments)     
                   The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with 
                   investing in those securities. For information about the Fund's policy regarding valuation of investments and 
                   other significant accounting policies, please refer to the Fund's most recent financial statements as contained in 
                   its semi-annual report.     
                   The following table summarizes the inputs used as of July 31, 2009 in determining the fair valuation of the Fund's 
                   investments:
