Fair value is defined as the price that the Trust would receive to sell an investment or pay to
   
transfer a liability in an orderly transaction with an independent buyer in the principal market,
   
or in the absence of a principal market the most advantageous market for the investment
   
or liability. There are three different categories for valuations. Level 1 valuations are
   
those based upon quoted prices in active markets. Level 2 valuations are those based upon
   
quoted prices in inactive markets or based upon significant observable inputs (e.g. yield
   
curves; benchmark interest rates; indices). Level 3 valuations are those based upon unobservable
inputs (e.g. discounted cash flow analysis; non-market based methods used to
   
determine fair valuation).
               
                 
The Trust values Level 1 securities using readily available market quotations in active markets.
   
The Trust values Level 2 fixed income securities using independent pricing providers
   
who employ matrix pricing models utilizing market prices, broker quotes and prices of securities
 
with comparable maturities and qualities. The Trust values Level 2 equity securities
   
using various observable market inputs in accordance with procedures established in good
   
faith by management and approved by the Board of Trustees. There were no
   
transfers between Level 1 and Level 2 during the period ended February 29, 2012.
