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

 (b) 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 rates or the undistributed net investment income
     balances will remain constant.

 (c) Calculated using the accumulated balance at July 31, 2007.

 (d) Calculated using the average fiscal year-to-date month-end
     balances for the three months ended July 31, 2006.
