 (a) Net assets are inclusive of market value of Preferred Shares of
     $270 million.

 (b) Calculated using the month-end balances for the three months ended
     June 30, 2006 and June 30, 2005, respectively.  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 undistibuted (overdistributed) net
     investment income balances. 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 (overdistributed) net investment income balance will
     remain constant.
