 3-Month Average Undistributed Net
  Investment Income Per Common Share(b)  $0.3783                NA

 (b) Calculated using the month-end balances for the three months
     ended April 30, 2005. Please note that generally there is a close
     correlation between what the Fund earns (net of expenses) and
     what it pays in monthly dividends. However, since net earning
     rates fluctuate from month to month while monthly dividends have
     remained relatively stable, there will be periods when the Fund
     may modestly over-earn or under-earn its monthly dividend which
     would have the effect of adding to or subtracting from the Fund's
     undistributed net investment income balance. Fund management
     analyzes the Fund's current and projected net earning rates prior
     to recommending dividend amounts to the Fund's Board of Trustees
     for declaration. There can be no assurance that the current
     dividend rate or the undistributed net investment income balance
     will remain constant.
