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, repayment 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 Fund’s 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 Fund’s policy regarding valuation 
of investments and other significant accounting policies, please refer to 
the Fund’s most recent financial statements as contained in its annual 
report.
