•Fair Value Measurements - Various inputs are used in determining the fair value of
investments and derivative financial instruments. These inputs are summarized in three broad
levels for financial reporting purposes 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, prepayment
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 and derivative financial
instruments )

The inputs or methodologies 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 derivative financial instruments and other significant
accounting policies, please refer to the Fund’s most recent financial statements as contained in
its semi-annual report.

The following tables summarize the inputs used as of April 30, 2011 in determining the fair
valuation of the Fund's investments and derivative financial instruments:
