                                      --------------------------------
                                           2007              2006
                                      --------------    --------------
 Net Investment Income (b)              $151,905,944      $144,719,254
 Per Common Share (b)                          $1.31             $1.25
 Net Realized and Change
  in Unrealized Gain (Loss) (b)        $(172,762,594)      $57,416,895
 Per Common Share (b)                         $(1.49)            $0.50

  (a) Net assets are inclusive of market value of Preferred Shares
      of $900 million.

  (b) The information provided is in accordance with generally
      accepted accounting principles ("GAAP"), which requires the Fund
      to treat amounts received (paid) under swap agreements as net
      realized gain (loss). However, these amounts are treated as net
      income (loss) for federal income tax purposes. By using GAAP,
      Net Investment Income for the quarter and nine months ended
      December 31, 2007 was $8,892,244 ($0.07 per common share) and
      $22,401,759 ($0.19 per common share) lower, respectively (and
      Net Realized and Change in Unrealized Gain (Loss)
      correspondingly higher (lower)) than those figures would have
      been if swap amounts were treated as net income (loss) in
      accordance with federal income tax treatment. By using GAAP, Net
      Investment Income for the quarter and nine months ended December
      31, 2006 was $5,070,895 ($0.05 per common share) and $14,832,211
      ($0.13 per common share) lower, respectively (and Net Realized
      and Change in Unrealized Gain (Loss) correspondingly higher
      (lower)) than those figures would have been if swap amounts
      treated as net income (loss) in accordance with federal income
      tax treatment.

  (c) 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 over-earn or
      under-earn its monthly dividend, which would have the effect of
      adding to or subtracting from the Fund's undistributed
      (overdistributed) net investment income balance. Fund management
      analyzes the current and projected net earning rates prior to
      recommending dividend amounts to the Fund's Board of Trustee for
      declaration. There can be no assurance that the current dividend
      rate or the undistributed (overdistributed) net investment
      income balance will remain constant. Inclusive of amounts earned
      under swap agreements, in accordance with federal income tax
      treatment.

  (d) Calculated using the accumulated balance at December 31, 2007.

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