Ÿ The Trust 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 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 circumstance, to the extent
observable inputs are not available (including the Trust's own assumption 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.

The following table summarizes the inputs used as of March 31, 2009 in determining the fair valuation of the
Trust's investments:

  Inputs    Securities
