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, 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 Trusts own assumptions used in determining the fair value of investments) |
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 Trusts policy regarding valuation of investments and other significant accounting policies, please refer to the Trusts most recent financial statements as contained in its annual report.
The following table summarizes the inputs used as of October 31, 2010 in determining the fair valuation of the Trusts investments:
