PREFERRED INCOME OPPORTUNITY FUND INCORPORATED

Dear Shareholder:

     The Preferred Income Opportunity Fund turned in a banner quarter despite an
extremely difficult market for fixed income securities.  The Fund earned 2.6% on
net asset value  ("NAV")  during its third fiscal  quarter.  For the first three
fiscal quarters of 2003, the return on NAV was a remarkable 22.9%.

     The extraordinary  jump in intermediate and long-term interest rates during
the quarter provided a textbook case for why we hedge against a substantial rise
in interest rates. The yields on 10-year and 30-year U.S.  Treasuries rose 1.10%
and 0.86%,  respectively,  during the period.  An  investor in these  securities
would have suffered  total return LOSSES of 7.8% on the 10-year and 10.9% on the
30-year.

     Given the magnitude of the weakness in the fixed-income  markets,  it is no
surprise that the  performance  of the market price for the Fund's shares lagged
the  performance  of the NAV. For the  quarter,  the return on market was -2.5%.
Since the  beginning  of the  fiscal  year,  the  market  return was a much more
impressive +12.7%.

     This was  clearly  one of the worst  three  months the bond market has ever
experienced, and without the Fund's hedging strategy the results would have been
much worse. In some ways, hedging is a lot like buying an insurance policy - you
pay a  premium,  but  don't  expect to  collect  very  often.  When you need it,
however,  you are awfully glad you have it! During the past quarter we certainly
needed the hedge;  WITHOUT IT, THE RETURN ON NAV WOULD HAVE BEEN 4.8  PERCENTAGE
POINTS LOWER.

     Interest in preferred securities remains high, but on balance there has not
been a lot of new supply. As you would expect, these conditions have resulted in
the yields on  preferreds  narrowing  versus the  yields on  Treasury  notes and
bonds.  Despite  this,  when  compared to  historical  relationships,  preferred
securities still appear attractively priced at present.

     We are always on the  lookout  for the best  values  within  the  preferred
securities  market.  For  some  period  of time  now,  we have  determined  that
traditional  preferred stock (the type which pays dividends that may be taxed at
lower rates for corporations  and individuals)  should comprise a larger portion
of the Fund's  investment  portfolio.  Of course,  in the future,  fully taxable
hybrid preferred securities may become more attractive and make up a bigger part
of the portfolio.

     A lot of  investors  have  inquired  about  the  percentage  of the  Fund's
distributions  which are dividends (as opposed to interest).  Because of the way
the tax rules work, that number cannot be calculated until the end of the fiscal
year.  We have added a section on the Fund's web site,  www.preferredincome.com,
which shows the breakdown between dividends, income and capital gains from prior
years.

     We strongly  encourage  shareholders  to participate in the Fund's Dividend
Reinvestment  and Cash Purchase Plan  ("DRIP").  It provides a steady,  reliable
approach to building wealth.

     Sincerely,

     /S/ Donald F. Crumrine                     /S/ Robert M. Ettinger

     Donald F. Crumrine                         Robert M. Ettinger
     Chairman of the Board                      President
