the Investment Company Act of 1940, were as follows:

Ÿ Effective August 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:

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 assumption 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
