Securities valuation policies and other investment related disclosures are hereby incorporated by reference to the annual and semi-annual reports previously filed with the Securities and Exchange Commission on Form N-CSR.

                           These inputs are summarized in the three broad levels listed below. 

                           Level 1 - quoted prices in active markets for identical securities. 

                           Level 2 - other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speed 

                           credit risk, etc.) 

                           Level 3 - significant unobservable inputs (including fund's own assumptions 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. 

The following is a summary of the inputs used as of August 31, 2008 in valuing the fund's investments carried 

                           at fair value: 

Valuation Inputs	Investments in Securities ($)	Other Financial Instruments* ($)
