Ÿ 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:

Ÿ Level 1 - price quotations in active markets/exchanges for identical securities
Ÿ 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 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)

Ÿ Level 3 - unobservable inputs based on the best information available in the circumstance, 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 April 30, 2009 in determining the fair valuation of the Fund's
investments:

Valuation    Investments in 
Inputs    Securities 
    Assets 
Level 1  $  7,105,539 
Level 2    451,403,899
