    Net Investment Income
    Per Common Share (b)         $0.2530                         0.3668

 (a) Net assets are inclusive of market value of Preferred Shares of
 $200 million.

 (b) Calculated using the month-end balances for the three months ended
 July 31, 2006 and July 31, 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 undistributed net investment income balance. Fund management
 analyzes the Fund's current and projected net earning rates prior to
 recommending dividend amounts to the 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.
