Various inputs are used in determining the value of the fund's investments relating to Financial Accounting Standard No. 157 (FAS 157), 
Fair Value Measurements. 
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 speeds, 
credit risk, etc.) 
Level 3 - significant unobservable inputs (including fund's own assumption 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 example, money market securities are valued using amortized cost, in accordance with rules under the Investment 
Company Act of 1940. Generally, amortized cost approximates the current fair value of a security, but since the value is not obtained 
from a quoted price in an active market, such securities are reflected as Level 2. 
The following is a summary of the inputs used as of April 30, 2008 in valuing the fund's assets carried 
at fair value: 

Valuation Inputs    Investments in Securities ($)    Other Financial Instruments* ($)     
Level 1 - Quoted Prices    0        0 
Level 2 - Other Significant Observable Inputs    883,958,211        0 
Level 3 - Significant Unobservable Inputs    0        0 
Total    883,958,211        0 

*Other financial instruments are derivative instruments not reflected in the Portfolio of Investments, such as futures, forwards and swap contracts, which are valued at the unrealized appreciation/depreciation on the instrument.
