• 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 Trust'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 Trust's policy regarding valuation of
investments and other significant accounting policies, please refer to the Trust's most recent financial
statements as contained in its annual report.
