Ÿ Effective September 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 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)

Ÿ 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 May 31, 2009 in determining the fair valuation of the
Fund's investments:
