Schedule of Investments November 30, 2009 (Unaudited)

• Fair Value Measurements - Various inputs are used in determining the fair value of
investments, which are as follows:
• Level 1 - price quotations in active markets/exchanges for identical assets and
liabilities
• 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, prepayments speeds, loss severities, credit risks
and default rates) or other market-corroborated inputs)

• 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 annual report.

The following table summarizes the inputs used as of November 30, 2009 in
determining the fair valuation of the Fund's investments:
