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) as level 3.
