Various inputs are used in determining the value of the Trust's investments. These inputs are summarized in the three broad levels below.
 
   
Level 1 - quoted prices in active markets for identical securities.
 
Level 2 - other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment
 
speeds, credit risks, etc.).
 
Level 3 - significant unobservable inputs (including the Trust's own assumptions in determining fair value of investments).
 
 
 
   
Generally, equity securities are categorized as Level 1, fixed income securities and senior loans are categorized as Level 2, and securities valued using fair value methods (other than prices supplied by independent pricing services or broker dealers) as Level 3.
 
   
The following is a summary of the inputs used as of December 31, 2014, in valuing the Trust's investments.
