ITEM 1. REPORTS TO STOCKHOLDERS.

The Report to Shareholders is attached herewith.

FLAHERTY & CRUMRINE PREFERRED INCOME OPPORTUNITY FUND

To the Shareholders of Flaherty & Crumrine Preferred Income Opportunity Fund:

     The fiscal year ended on a positive note, posting solid returns for the
third consecutive quarter. As can be seen in the table below, the eye-popping
performance of recent periods tells only part of the story, but one we are happy
to report!

----------
(1)  In prior periods, the Fund included the performance of funds in Lipper's
     Domestic Investment-Grade funds category, which reflected the
     equally-weighted average performance returns of all closed-end funds in the
     category in each month during the period. The category last included
     closed-end funds in the U.S. Mortgage and Corporate Debt BBB Rated
     sub-categories and has included other sub-categories in prior periods. With
     Lipper no longer publishing these results in a comparable format, the Fund
     will no longer include these results. For the period ended November 30,
     2009, this category returned 5.8%, 15.4%, 31.0%, 3.9%, 4.5%, 6.2% and 6.5%
     (for the three month, six month, one year, three year, five year, ten year
     and since inception periods).

(2)  Since inception on February 13, 1992.

(3)  The Barclays Capital U.S. Aggregate Index represents securities that are
     SEC-registered, taxable, and dollar denominated. The index covers the U.S.
     investment grade fixed rate bond market, with index components for
     government and corporate securities, mortgage pass-through securities, and
     asset-backed securities. It is generally considered to be representative of
     the domestic, investment-grade, fixed-rate, taxable bond market. Unless
     otherwise noted, index returns reflect the reinvestment of dividends and
     capital gains, if any, but do not reflect fees, brokerage commissions or
     other expenses of investing. This index was formerly known as the Lehman
     Brothers U.S. Aggregate Index.

(4)  The S&P 500 is a capitalization-weighted index of 500 stocks. The index is
     designed to measure performance of the broad domestic economy through
     changes in the aggregate market value of 500 stocks representing all major
     industries.

     The financial crisis of the past two years claimed countless casualties and
caused greater market volatility in the preferred market than any time in
memory. A double digit return, up or down, was unusual before the crisis, yet
such numbers have recently become more common.(1)

     For all of fiscal 2009, the NAV INCREASED 88.4% as the market for preferred
securities came back to life. Although recent performance is impressive, it has
not been enough to offset the decline of 48.1% in fiscal 2008. Unfortunately, it
takes a lot more positive percentage returns to overcome a given amount of
negative return. And if that's not enough to induce some head scratching, the
analysis is further complicated by changes in the amount of leverage used by the
Fund. We delve more deeply into these numbers, as well as returns on the market
price of Fund shares, in the discussion section.

----------
(1)  The Fund's interest rate hedging strategy generally helps dampen volatility
     of returns, but the decision to temporarily suspend such hedging late last
     year has had little impact on performance (more on this later).



     To help readers put the Fund's performance in context, we've included
returns for broader fixed-income and equity markets. Other performance
comparisons are discussed more thoroughly in the discussion section which
follows.

     Conditions in the preferred securities market have improved dramatically.
Efforts by various government agencies, especially the Federal Reserve, have
clearly helped stabilize the financial sector; prices of securities issued by
commercial banks and insurance companies have recovered much of their lost
value. Another factor contributing to the rebound in the preferred market is the
absence of alternative investments such as asset-backed securities,
collateralized debt obligations and commercial mortgage-backed securities.
Investors have returned to more traditional investments like preferred
securities, as the supply of "alternative" products has virtually disappeared.

     Although risks remain, the outlook for the preferred securities market
seems bright. Market liquidity has improved and new securities are being issued.
Confidence in the banking sector has improved, as banks have repaid more than
70% of the TARP preferreds issued during the height of the financial crisis.
There are also indications that increased standardization of preferred security
structures may be coming down the road, something investors would welcome.

     The fact that the government used preferred stock investments to provide
capital to distressed companies is an indication of how important these
securities are in the world of finance. Without preferred securities, the number
of companies that failed during the financial crisis would likely have been far
greater.

     In another sign of better times, the Fund announced an increase in the
monthly distribution to $0.0575 from $0.050 beginning with the December 2009
dividend. Several factors contributed to the increase, including changes to the
Fund's leverage. The impact of leverage, investment income and Fund expenses on
the amount of the dividend can get confusing, but it is important for
shareholders to understand how the distributions are determined. We attempt to
clarify things a bit in the discussion section.

     More information is always available on the Fund's website, including
expanded discussion of many of the topics in this letter. In addition, our
thoughts on the economic outlook are published quarterly and posted to the site.
We encourage you to visit the website at www.preferredincome.com.

THE FUND'S PORTFOLIO RESULTS AND COMPONENTS OF TOTAL RETURN ON NAV

     The table below reflects the performance of each investment technique
available for use by the Fund to achieve its objective, namely: (a) investing in
a portfolio of securities; (b) hedging that portfolio of securities against
significant increases in long-term interest rates (see the following discussion
on interest rate hedging); and (c) utilizing leverage to enhance returns to
shareholders. Next, we compute the impact of the Fund's operating expenses. All
of the parts are summed to determine the total return on NAV.

----------


     By the end of the Fund's fiscal year ended November 30th, the preferred
market had recovered dramatically from the lows it reached in 2008 and early
2009. More importantly, as can be seen by comparing the total return on the
securities portfolio (the first row of the above table) to the index results in
the following table, the Fund's portfolio outperformed the three largest
segments of the market. The fourth segment of the market, adjustable rate
preferred securities, constitutes roughly 3% of the entire preferred market as
well as of the Fund's portfolio.

*    The Bank of America Merrill Lynch 8% Capped DRD Preferred Stock Index(SM)
     includes investment grade preferred securities issued by both corporations
     and government agencies that qualify for the corporate dividend received
     deduction with issuer concentration capped at a maximum of 8%. The Bank of
     America Merrill Lynch 8% Capped Hybrid Preferred Securities Index(SM)
     includes taxable, fixed-rate, U.S. dollar-denominated investment-grade,
     preferred securities listed on a U.S. exchange with issuer concentration
     capped at 8%. The Bank of America Merrill Lynch 8% Capped Corporate U.S.
     Capital Securities Index(SM) includes investment grade fixed rate or
     fixed-to-floating rate $1,000 par securities that receive some degree of
     equity credit from the rating agencies or their regulators with issuer
     concentration capped at a maximum of 8%. The Bank of America Merrill Lynch
     Adjustable Preferred Stock, 7% Constrained Index(SM) includes adjustable
     rate preferred securities issued by U.S. corporations and government
     agencies with issuer concentration capped at a maximum of 7%. All index
     returns include interest and dividend income and, unlike the Fund's
     returns, are unmanaged and do not reflect any expenses.


                                        3



     The bottom line of the Fund's performance (as well as the bottom line of
the first table) demonstrates how leverage benefited common stock shareholders
during the past year. In contrast to the experience during fiscal 2008, the
strategy of using leverage to increase current income magnified the positive
returns over the Fund's fiscal 2009, and, even net of its expenses, caused the
NAV of the Fund (with the added benefit of leverage) to significantly outperform
the three largest unleveraged preferred market indices.

TOTAL RETURN ON MARKET PRICE OF FUND SHARES

     While our focus is primarily on managing the Fund's investment portfolio,
an investor's actual return is comprised of monthly dividend payments plus
changes in the Fund's MARKET PRICE. After hitting lows in late 2008, the Fund's
market price improved dramatically in 2009, and for the twelve months ending
November 30, 2009, the total return on market price of Fund shares was +110.5%.

     In a perfect world the market price of Fund shares would closely track the
Fund's net asset value. As can be seen from the graph below, this often is not
the case. For most of the past year the market price has been below the NAV (in
market parlance, "trading at a discount"). Recently, the discount narrowed and
the market price is more in line with the underlying value of each Fund share.

monthly distribution of $0.0575 does not change) is 8.3%. In our opinion, this
distribution rate measures up favorably with most comparable investment
opportunities.

PREFERRED MARKET CONDITIONS

     Conditions in the preferred securities market have improved markedly since
the very dark days of last winter. By late February 2009, prices on preferred
securities had fallen to such a degree that the market seemed to be predicting
few companies would survive. And while the severe economic downturn did claim
its victims, the vast majority of companies appear to be well on the way to full
recovery.


                                        4



     By most measures, key aspects of the preferred market are returning to
normal levels. Trading has improved; there has been a steady supply of new
issues; market participation appears widespread; and valuation metrics appear
more consistent with other market segments. Of course, the most important
measure of whether the preferred market has returned to normal levels is price.
In our opinion, prices on much of the universe of preferred securities remain
attractive, especially when compared to pre-crisis levels.

     Since March, there have been almost thirty new preferred issues, totaling
over $16 billion. Although some of the new issues have been in exchange for
older preferred securities, there has been new supply, and investors appear to
have an appetite for more.

     Perceptions of credit quality have also improved recently. Bolstered by
banks returning bailout funds to the government (discussed below), investor
confidence is coming back. The market reacted positively to each announcement of
the Troubled Asset Relief Program (TARP) repayment, especially those of Bank of
America and Citigroup. In addition to paying back the government, a number of
banks raised new capital (common and preferred) in a sign that traditional
financing sources are opening up again.

     Though banks have the most preferred securities outstanding, preferred
securities of insurance companies and public utilities constitute the other
large sectors of the preferred securities universe. The insurance industry has
generally benefited from improved investment performance and very few natural
catastrophes. A number of insurance companies repurchased a portion of their
outstanding preferred securities in recent months; in turn, the market prices of
their remaining securities have risen substantially. Utilities, largely
unaffected by the financial crisis, have continued to perform well, as investors
seek perceived safety and diversification.

     From time to time, the national credit rating agencies, primarily Moody's,
Standard & Poor's, and Fitch, have revised the methodology they use to rate
preferred securities. We rely primarily on our own research to evaluate credit
quality, but the impact of public ratings can't be ignored. So when the agencies
recently announced changes (once again!) to the methodology they employ in
rating preferred securities, we were a bit dismayed. However, the market took it
in stride, and despite a number of downgrades, prices changed little, if at all.

     In December, a little known, but extremely important international
committee based in Basel, Switzerland, proposed stricter guidelines for the way
banks account for capital raised by issuing preferred securities. From our
initial read of the guidelines, it appears that, after a transition period, in
order for banks to receive the most favorable regulatory treatment from
preferred capital, the issues will have to look more like old fashioned
perpetual preferred stock. In addition, the U.S. Congress is considering new
regulations for financial institutions that will affect many of the issuers in
the Fund's portfolio. Of course, we'll monitor these developments closely and
keep you informed, but we are optimistic that these changes will be beneficial
to the Fund.

     The preferred securities market, much like the broader stock and bond
markets, took some severe hits during the financial crisis, and we still expect
some bumps in the road to complete recovery in our markets. That being said, we
aren't surprised by the extent of the ongoing recovery, even if the speed at
which it has occurred has been faster than we imagined.

BANK REPAYMENT OF TARP PREFERRED AND IMPACT ON PREFERRED INVESTORS

     In aggregate, U.S. banks have repaid about $188 billion of the roughly $264
billion in preferred capital purchased from them by the TARP. Focusing on the 19
largest banks that were subject to the Supervisory


                                        5



Capital Assessment Program (SCAP), 18 of these banks received approximately $221
billion in TARP capital and 12 of them have repaid about $182 billion as of
December 18, 2009(2). This has turned out to be a significantly faster timetable
for repayment than most market participants expected, and it highlights that (1)
policies implemented to protect the financial system were largely effective and
(2) the health of the banking system is improving rapidly.

     All of the money-center banks and most of the major trust banks have repaid
their TARP capital. These institutions have viewed repayment as important to
their business. They believe that customers have a higher degree of confidence
doing business - particularly when it involves counterparty risk - with a bank
that has repaid the Treasury.

     On the other hand, most regional and community banks have not yet repaid
their TARP capital. This is not a bad thing for preferred investors. Although
our assessment of their ability to repay TARP capital varies among regional and
community banks, we believe that it is prudent for them to hold on to the
capital at this time. While economic and financial conditions have improved,
aggregate loan losses are still increasing. We expect them to peak in 2010, but
some geographic regions and loan categories (e.g., commercial real estate) are
likely to turn around more slowly. Regional and community banks, particularly
smaller ones, tend to have more geographic, and often more loan-category,
concentration than larger money-center banks, which makes them more exposed to
those uncertainties. As a result, we do not fault these banks for holding on to
their TARP capital for a while longer. If the economic recovery proceeds as
expected and loan losses begin to trend down, we expect that most of the
remaining banks will repay their TARP capital in 2010. However, banks with tough
geographic footprints or concentrations of problem loans may not repay their
TARP capital for several more years, and some will not survive at all.

     As preferred investors, we care more about the quality of a bank's loan
book, its business prospects, and the quantity and composition of its capital
than whether or not it has repaid the TARP. We generally are happy to see banks
repay the Treasury as long as they issue a meaningful amount of common equity to
fund the repayment - something nearly all of the banks that have repaid the TARP
have done.

STATUS OF THE FUND'S HEDGING STRATEGY

     The Fund suspended its interest rate hedging program as the financial
crisis intensified in the autumn of 2008. There were three principal reasons why
we suspended the program at the time. First, the relationship between preferred
securities' prices and the Fund's hedging instruments (Treasury bond futures,
interest rate swaps, and options on both) was turned on its head during the
financial crisis. Historically, preferred prices had tended to rise (fall) in
periods of falling (rising) long-term Treasury rates, but as the financial
crisis unfolded, the opposite occurred: preferred prices plunged while Treasury
and swap rates fell as investors sold risky assets and raced into Treasuries.
This meant that hedging interest rates using put options on Treasury futures as
had been done historically added risk to the Fund, which emphatically is not the
objective of the hedging program. Second, the cost of hedging rose dramatically
as the yield curve steepened and options

(2)  Citigroup received a total of $45 billion in TARP capital and issued $7.1
     billion in additional preferreds to the U.S. Treasury as payment for
     insurance on $301 billion of troubled assets. Treasury later exchanged $25
     billion of TARP preferred for common equity. (We include this amount as
     "repaid," since it is no longer a Citigroup obligation.) As part of the
     repayment plan announced on December 14, 2009, Citigroup will repay the
     balance of $20 billion in TARP preferred, but $5.3 billion of the
     "additional preferreds" will remain outstanding. The other banks that have
     repaid their TARP capital are: American Express, Bank of America, BB&T
     Bank, Bank of New York Mellon, Capital One Financial, Goldman Sachs, JP
     Morgan Chase, Morgan Stanley, State Street Bank & Trust, U.S. Bancorp, and
     Wells Fargo


                                        6



prices rose sharply. Finally, preferred securities became exceptionally cheap
and were likely to offer high returns to shareholders even if Treasury yields
increased moderately. Add them up, and we believed that hedging simply would not
work under the market conditions at the time. (For a more detailed explanation,
see "Update on Hedging Strategy," July 6, 2009 on the Fund's web site.)

     Looking at the hedging strategy currently, we conclude that it remains too
early to reinstate the hedging program. Although some preferred securities are
starting to move in concert with the general level of long-term Treasury rates,
most are not. For the preferred market as a whole, correlations between
movements in prices of preferreds and the hedge instruments we use are
increasing, but they remain well below their historical levels. While hedging
today probably would not add to risk as it did during the height of the crisis,
it still would not do much to reduce it. Meanwhile, the cost of hedging remains
high, and preferreds remain attractively priced.

     However, it does appear that the preferred market is gradually moving back
toward a stronger relationship with swaps and Treasuries, even if that progress
is insufficient to persuade us to reestablish the hedging program at this time.
As the financial system heals, preferred securities are likely to reconnect with
long-term benchmark Treasury rates. When they do, we will consider hedging
again.

THE FUND'S LEVERAGE

     As we have discussed in the past, there have been important changes in the
Fund's leverage since the beginning of the credit crisis. Most notably, during
the past year, the Fund redeemed all of its remaining outstanding auction
preferred stock, and instead began using debt for leverage. Equally important,
the amount of leverage in the Fund in dollars and as a percent of total assets
has changed.

     Leverage is an important part of the Fund's strategy to produce high
current income. Over time, the cost of leverage is typically lower than the
yield on the Fund's portfolio. The difference between what the Fund earns on its
investments and pays on the money it borrows increases the income available to
common shareholders.

     The Fund began a process of transitioning from auction preferred leverage
to bank debt leverage in early 2008. When it worked as intended, auction
preferred stock was a very efficient form of leverage. However the breakdown of
the auction process in late 2007 prompted us to seek alternative leverage. We
determined that a borrowing facility was the best available option.

     In addition to economic considerations there is a set of rules that govern
leverage (most importantly, the terms and conditions of the leverage agreement,
and all relevant securities laws). We take all of these factors into
consideration as we manage the leverage AND the assets of the Fund.

     There are two useful measures of how much leverage the Fund has in place.
The first is simply the total dollar amount of leverage. The other measure is
the ratio of the Fund's assets financed by that leverage (in other words, the
amount of leverage divided by total assets). The chart below presents both
measures of leverage over the past three years.

     When the leverage was comprised entirely of auction preferred stock, the
AMOUNT of leverage rarely changed. As a result, the PERCENTAGE of the Fund's
leverage to total net assets varied as the value of the portfolio moved up or
down. As can be seen in the chart, the leverage percentage climbed steadily as
the financial crisis unfolded and the value of the Fund's investment portfolio
fell.

     As the leverage ratio rose to unsustainable levels, the Fund sold assets
and used the proceeds to reduce leverage. While this meant that monthly
distributions to shareholders had to be cut, it also served to reduce the NAV
and market price risk to the Fund's common shareholders.

     With debt leverage, it has been easier and less expensive to INCREASE the
amount borrowed by the Fund (within certain limits!). This is important because
the dramatic recovery in asset prices meant the Fund could comfortably borrow
more and use the money to purchase additional securities.

     The "right" amount of leverage is never a simple matter to determine. Type
of borrowing, the cost of funds and market conditions will all be factors to
consider. At present, we are comfortable with the amount of the leverage. We
continuously monitor these factors and try to use leverage in a manner most
consistent with the Fund's objectives.

MONTHLY DISTRIBUTIONS TO FUND SHAREHOLDERS

     The monthly distribution paid to shareholders is intended to reflect
current market conditions, but we also must make assumptions about the future.
We begin with an estimate of the sustainable income generated from the
investment portfolio, and end with a forecast of expenses, including the cost of
leverage. While it sounds simple, in periods of rapid change, forecasting income
and expenses becomes more art than science. There are always a lot of moving
parts when the Fund sets the monthly distribution, and the present is no
different.

     With regard to income earned by the Fund, the financial crisis has claimed
many victims and there are a few Fund portfolio holdings that are not currently
making dividend or interest payments (noted as "non-


                                        8



income producing" in the portfolio listing that follows). This obviously has a
direct impact on our forecasted income.

     Historically, the Fund's use of auction preferred stock as leverage
encouraged it to invest in tax-advantaged (DRD-eligible) securities. As the Fund
has transitioned away from auction preferred stock, its portfolio has also
shifted to much greater percentages of fully-taxable securities. On a pre-tax
basis, this has had a positive impact on the amount of income earned by the
Fund, since fully-taxable securities typically yield more than tax-advantaged
ones. Of course, as detailed in the Supplementary Tax Information below, the
amount of income eligible for the corporate dividends received deduction (DRD)
has accordingly decreased.

     The primary variables on the expense forecast are the cost and amount of
leverage employed by the Fund. During the year, we saw two different trends.
Late in 2008, the reduction in the AMOUNT of leverage (and the amount of
additional incremental income it provided) dwarfed the benefit the Fund would
have seen from its declining COST of leverage. As a result, the Fund began its
fiscal year with a dividend cut. In the second half of 2009, the Fund saw both
variables trend positive: the cost of leverage continued to drop and the amount
of leverage was increased. As we discussed in the shareholder letter, the
additional income provided by that additional leverage consequently allowed the
Fund to increase its dividend.

IMPACT OF THE FEDERAL RESERVE RAISING SHORT-TERM RATES

     With the federal funds rate hovering near zero percent, it's fair to ask
what will happen to the Fund when the Fed inevitably raises short-term rates. We
have to start with the caveat that there is no comprehensive answer, since the
Fund's performance depends on a lot more than the fed funds rate, which is the
only interest rate that the Fed controls directly. Having said that, we believe
there are several likely repercussions of Fed tightening.

     Higher short-term rates are likely to reduce income available to the Fund's
common stock shareholders. The Fund's cost of leverage would go up, whereas most
of the Fund's assets pay fixed dividends or interest. The Fund could hedge this
risk by fixing the cost of leverage for some period of time, but doing so would
certainly increase the cost of leverage today in exchange for possibly lowering
it in the future. Because the yield curve currently is steep, the market expects
short rates will rise significantly and soon. As of December 31, 2009, the
market was pricing-in 25-50 basis points (bp) of tightening by the Fed by June
2010, 100-125 bp of tightening by the end of 2010, and more than 250 bp of
tightening by the end of 2011. Hedging the cost of leverage locks in those
expected rate increases. Short-term interest rates may rise by more than that,
but we currently think the economic outlook favors low rates for a longer period
than the market expects. Nonetheless, when short-term rates eventually do rise,
it probably will strain the Fund's dividend.

     While the impact of higher short-term rates on income is fairly clear,
their impact on preferred securities' prices is ambiguous. Higher short-term
rates normally are associated with higher long-term rates and lower preferred
prices. However, we don't think these are normal times! The Fed is not likely to
raise short-term rates until the economy is stronger, which in turn should be
positive for the credit outlook. With preferred valuations still being driven
more by credit developments than by the general level of interest rates, Fed
tightening - at least in moderate amounts - might actually be good news for
preferred prices. In addition, if the Fed tightens by less than the market
expects, long-term rates could fall, just as they did when the Fed tightened in
2004-05. In short, it's not obvious that long-term interest rates are set to
rise, even though higher short-term rates are inevitable at some point - and
it's even less clear that tighter monetary policy would be bad news for
preferreds. (This is another reason why the Fund's hedging program is on hold.)


                                        9


     Implicit in this analysis is the view that the Fed will not have to raise
short-term rates dramatically, which probably would push all rates higher. The
only reason we could anticipate such high short-term rates is a breakout of
inflation. Given soaring budget deficits and accommodative monetary policy,
sharply higher inflation down the road cannot be ruled out. However, as we have
discussed in recent Economic Updates, we do not think inflation will gain a
foothold over the near to medium term. If we are right about that, we think the
main impact of moderately tighter monetary policy on the Fund is likely to be
somewhat reduced income.

FEDERAL TAX ADVANTAGES OF 2009 CALENDAR YEAR DISTRIBUTIONS

     In 2009, the Fund passed on a portion of its income to individuals in the
form of qualified dividend income or QDI. Under federal law, QDI is taxed at a
maximum 15% rate instead of an individual's ordinary income tax rate. In
calendar year 2009, approximately 48.9% of distributions made by the Fund was
eligible for QDI treatment. For an individual in the 28% tax bracket, this means
that the Fund's total distributions will only be taxed at a blended 21.6% rate
versus the 28% rate which would apply to distributions by a fund containing
traditional corporate bonds. This tax advantage means that, all other things
being equal, an individual in the 28% tax bracket who held 100 shares of Common
Stock of the Fund for the calendar year would have had to receive approximately
$66 in distributions from a traditional corporate bond fund to net the same
after-tax amount as the $61 in distributions paid by the Fund.

     For detailed information about the tax treatment of the particular
distributions received from the Fund, please see the Form 1099 you receive from
either the Fund or your broker.

     Corporate shareholders also receive a federal tax benefit from the 35.1% of
distributions that were eligible for the inter-corporate dividends received
deduction or DRD.

     It is important to remember that the composition of the portfolio and the
income distributions can change from one year to the next, and that the QDI or
DRD portions of 2010's distributions may not be the same (or even similar) to
2009.

     AS PREVIOUSLY DISCUSSED, THE FUND REDEEMED ALL OF ITS OUTSTANDING AUCTION
PREFERRED STOCK DURING THE PAST YEAR AND BEGAN USING DEBT FOR LEVERAGE. THE
FOLLOWING DESCRIBES RISKS ASSOCIATED WITH LEVERAGING THE FUND THROUGH THE USE OF
BORROWING, WHICH DO NOT MATERIALLY DIFFER FROM THE RISKS THE FUND FORMERLY FACED
THROUGH LEVERAGING USING AUCTION PREFERRED STOCK.

     Because the investment risk associated with investment assets purchased
with funds obtained through leveraging is borne solely by each Fund's Common
Stock shareholders, adverse movements in the price of the Fund's portfolio
holdings would have a more severe effect on the Fund's net asset value than if
the Fund were not leveraged. Leverage creates risks for the Fund's Common Stock
shareholders, including the likelihood of greater volatility of the Fund's net
asset value and the market price of its shares, and the risk that fluctuations
in interest rates on borrowings may affect the return to Common Stock
shareholders. If income from the securities purchased with such funds is not
sufficient to cover the cost of leverage, net income of the Fund would be less
than if leverage had not been used, and therefore the amount available for
distribution to Common Stock shareholders as dividends will be reduced. In such
an event, the Fund may nevertheless determine to maintain its leveraged position
in order to avoid capital losses on securities purchased with the leverage.
Further, all expenses associated with borrowing, such as interest expenses and
transaction costs, will be borne solely by the Fund's Common Stock shareholders.

     If the asset coverage for borrowing declines below the limits specified in
the Investment Company Act of 1940 (the "1940 Act") or in the terms of the
financing arrangement, the Fund might be required to sell a


                                       10



portion of its investments when it is not advantageous to do so. In the extreme,
sales of investments required to meet asset coverage tests imposed by the 1940
Act could also cause a Fund to lose its status as a regulated investment company
under the Internal Revenue Code of 1986, as amended (the "Code"). If a Fund were
unable to make adequate distributions to shareholders because of asset coverage
or other restrictions, it could fail to qualify as a regulated investment
company for federal income tax purposes, and, even if it did not fail to so
qualify, it could become liable for income and excise tax on the portion of its
earnings which are not distributed on a timely basis in accordance with
applicable provisions of the Code.

     ON APRIL 21, 2009, THE FUND'S SHAREHOLDERS APPROVED A CHANGE IN ITS
CONCENTRATION POLICY SO THAT IT WILL INVEST AT LEAST 25% OF ITS TOTAL ASSETS IN
EACH OF THE UTILITIES INDUSTRY AND THE FINANCIAL SERVICES SECTOR UNDER NORMAL
MARKET CONDITIONS. FORMERLY, THE FUND INVESTED MORE THAN 25% OF ITS TOTAL ASSETS
IN THE UTILITIES INDUSTRY UNDER NORMAL MARKET CONDITIONS AND LIMITED ITS
INVESTMENTS IN ANY OTHER INDUSTRY TO 25%. THE FOLLOWING DESCRIBES RISKS
ASSOCIATED WITH INVESTING IN THE FINANCIAL SERVICES SECTOR.

     U.S. and foreign laws and regulations require commercial banks and bank
holding companies to maintain minimum levels of capital and liquidity, and to
establish loan loss reserves. A bank's failure to maintain specified capital
ratios may trigger dividend restrictions, suspensions on payments on
subordinated debt, and limitations on growth. Bank regulators have broad
authority in these instances and can ultimately impose sanctions, including
conservatorship or receivership, on such non-complying banks even when these
banks continue to be solvent, thereby possibly resulting in the elimination of
stockholders' equity. Unless a bank holding company has subsidiaries other than
banks that generate substantial revenues, the holding company's cash flow and
ability to declare dividends may be impaired severely by restrictions on the
ability of its bank subsidiaries to declare dividends.

     Similarly, U.S. and foreign laws and regulations require insurance
companies to maintain minimum levels of capital and liquidity. An insurance
company's failure to maintain these capital ratios may also trigger dividend
restrictions, suspensions on payments of subordinated debt, and limitations on
growth. Insurance regulators (at the state-level in the United States) have
broad authority in these instances and can ultimately impose sanctions,
including conservatorship or receivership, on such non-complying insurance
companies even when these companies continue to be solvent, thereby possibly
resulting in the elimination of shareholders' equity. In addition, insurance
regulators have extensive authority in some categories of insurance of approving
premium levels and setting required levels of underwriting.

     Governmental fiscal and monetary policies and general economic and
political conditions can affect the availability and cost of funds to financial
services companies, loan demand and asset quality and thereby impact the
earnings and financial condition of financial services companies. In addition,
the enactment of new legislation and regulation, as well as changes in the
interpretation and enforcement of existing laws and regulations, may directly
affect the manner of operations and profitability of participants in the
financial services sector. Downturns in a national, regional or local economy or
in the general business cycle or depressed conditions in an industry, for
example, may adversely affect the quality or volume of a bank's loan portfolio
or an insurance company's investment portfolio, particularly if the portfolio is
concentrated in the affected region, industry or market sector. From time to
time, general economic conditions have adversely affected financial
institutions' energy, agricultural, commercial and/or residential real estate,
less-developed country, venture capital, technology, telecommunications, and
highly-leveraged loan portfolios.


                                       11



     Since September 2008, the financial services sector has experienced
unprecedented turbulence. The U.S. economy's recession, led by the downturn in
the housing industry, adversely affected the quality of most financial services
companies' loan and securities portfolios. Loan charge-offs and mark-to-market
losses have caused the capital ratios and overall financial condition of most
financial services companies to deteriorate. In response, U.S. and foreign
governments purchased significant equity capital positions in many banks and
some insurance companies. Governments held a greater amount of preferred stock
in some issuers than the total outstanding public preferred stock of that
issuer. The full impact of government actions and deteriorating economic
conditions is still unknown and could continue to adversely affect financial
services companies. The impact of a deteriorating economy or industry upon
institutions depends, in part, on the size of the institutions, the extent to
which they are involved in the type of lending or market affected, the duration
of the softening in the affected area and the managerial and capital resources
of the financial institutions. In addition, changes in accounting rules
applicable to loans and investment securities also may adversely impact the
financial condition of these institutions.

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated
NOTES TO FINANCIAL STATEMENTS

1.   ORGANIZATION

     Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated (the
"Fund") was incorporated as a Maryland corporation on December 10, 1991, and
commenced operations on February 13, 1992 as a diversified, closed-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Fund's investment objective is to provide its
common shareholders with high current income consistent with the preservation of
capital.

2.   SIGNIFICANT ACCOUNTING POLICIES

     The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of the financial statements is in conformity with U.S. generally
accepted accounting principles ("US GAAP") and requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities in the financial statements and the reported amounts of increases
and decreases in net assets from operations during the reporting period. Actual
results could differ from those estimates.

     PORTFOLIO VALUATION: The net asset value of the Fund's Common Stock is
determined by the Fund's Administrator no less frequently than on the last
business day of each week and month. It is determined in accordance with the
policies and procedures approved by the Board of Directors of the Fund by
dividing the value of the Fund's net assets available to Common Stock by the
number of shares of Common Stock outstanding. The value of the Fund's net assets
available to Common Stock is deemed to equal the value of the Fund's total
assets less (i) the Fund's liabilities and (ii) the aggregate liquidation value
of any outstanding preferred stock.

     The Fund's preferred and debt securities are valued on the basis of current
market quotations provided by independent pricing services or dealers approved
by the Board of Directors of the Fund. Each quotation is based on the mean of
the bid and asked prices of a security. In determining the value of a particular
preferred or debt security, a pricing service or dealer may use information with
respect to transactions in such investments, quotations, market transactions in
comparable investments, various relationships observed in the market between
investments, and/or calculated yield measures based on valuation technology
commonly employed in the market for such investments. Common stocks that are
traded on stock exchanges are valued at the last sale price or official close
price on the exchange, as of the close of business on the day the securities are
being valued or, lacking any sales, at the last available mean price. Futures
contracts and option contracts on futures contracts are valued on the basis of
the settlement price for such contracts on the primary exchange on which they
trade. Investments in over-the-counter derivative instruments, such as interest
rate swaps and options thereon ("swaptions"), are valued using prices supplied
by a pricing service, or if such prices are unavailable, prices provided by a
single broker or dealer that is not the counterparty or, if no such prices are
available, at a price at which the counterparty to the contract would repurchase
the instrument or terminate the contract. Investments for which market
quotations are not readily available or for which management determines that the
prices are not reflective of current market conditions are valued at fair value
as determined in good faith by or under the direction of the Board of Directors
of the Fund, including reference to valuations of other securities which are
comparable in quality, maturity and type.

              Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated
                                       NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     Investments in money market instruments and all debt and preferred
securities which mature in 60 days or less are valued at amortized cost.
Investments in money market funds are valued at the net asset value of such
funds.

     FAIR VALUE MEASUREMENT: The inputs and valuation techniques used to measure
fair value of the Fund's investments are summarized into three levels as
described in the hierarchy below:

     -    Level 1 - quoted prices in active markets for identical securities

     -    Level 2 - other significant observable inputs (including quoted prices
                    for similar securities, interest rates, prepayment speeds,
                    credit risk, etc.)

     -    Level 3 - significant unobservable inputs (including the Fund's own
                    assumptions in determining the fair value of investments)

     The inputs or methodology used for valuing securities are not necessarily
an indication of the risk associated with investing in those securities. A
summary of the inputs used to value the Fund's investments as of November 30,
2009 is as follows:



                                                                  LEVEL 2        LEVEL 3

     Following is a reconciliation of Level 3 investments for which significant
unobservable inputs were used to determine fair value:

BALANCE AS OF 11/30/09 ............................    $   24,750   $   24,750


     For the year ended November 30, 2009, total change in unrealized
gain/(loss) on Level 3 securities still held at year-end and included in the
change in net assets was $(2,337,750). Total unrealized gain/(loss) for all
securities (including Level 1 and Level 2) can be found on the accompanying
Statement of Operations.

     SECURITIES TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are
recorded as of the trade date. Realized gains and losses from securities sold
are recorded on the specific identified cost basis. Dividend income is recorded
on ex-dividend dates. Interest income is recorded on the accrual basis. The Fund
also amortizes premiums and accretes discounts on fixed income securities using
the effective yield method.

     OPTIONS: In the normal course of pursuing its investment objectives, the
Fund is subject to interest rate risk and may purchase or write options to hedge
against this risk. Purchases of options are recorded as an investment, the value
of which is marked-to-market at each valuation date. When the Fund enters into a
closing sale transaction, the Fund will record a gain or loss depending on the
difference between the purchase and sale price. The risks associated with
purchasing options and the maximum loss the Fund would incur are limited to the
purchase price originally paid.

     When the Fund writes an option, an amount equal to the premium received by
the Fund is recorded as a liability, the value of which is marked-to-market at
each valuation date. When a written option expires, the Fund realizes a gain
equal to the amount of the premium originally received. When the Fund enters
into a closing purchase transaction, the Fund realizes a gain (or loss if the
cost of the closing purchase transaction exceeds the premium received when the
option was written) without regard to any unrealized gain or loss on the
underlying security, and the liability related to such option is eliminated.
When a call option is exercised, the Fund realizes a gain or loss from the sale
of the underlying security and the proceeds from such sale are increased by the
amount of the premium originally received. When a put option is exercised, the
amount of the premium originally received will reduce the cost of the security
which the Fund purchased upon exercise.


                                       28



              Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated
                                       NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     The risk in writing a call option is that the Fund may forego the
opportunity for profit if the market price of the underlying security increases
and the option is exercised. The risk in writing a put option is that the Fund
may incur a loss if the market price of the underlying security decreases and
the option is exercised. There were no purchased or written options for the year
ended November 30, 2009.

     REPURCHASE AGREEMENTS: The Fund may engage in repurchase agreement
transactions. The Fund's investment adviser reviews and approves the eligibility
of the banks and dealers with which the Fund may enter into repurchase agreement
transactions. The value of the collateral underlying such transactions is at
least equal at all times to the total amount of the repurchase obligations,
including interest. The Fund maintains possession of the collateral through its
custodian and, in the event of counterparty default, the Fund has the right to
use the collateral to offset losses incurred. There is the possibility of loss
to the Fund in the event the Fund is delayed or prevented from exercising its
rights to dispose of the collateral securities.

     FEDERAL INCOME TAXES: The Fund intends to continue to qualify as a
regulated investment company by complying with the requirements under subchapter
M of the Internal Revenue Code of 1986, as amended, applicable to regulated
investment companies and intends to distribute substantially all of its taxable
net investment income to its shareholders. Therefore, no federal income tax
provision is required.

     Management has analyzed the Fund's tax positions taken on Federal income
tax returns for all open tax years (November 30, 2009, 2008, 2007 and 2006), and
has concluded that no provision for federal income tax is required in the Fund's
financial statements. The Fund's major tax jurisdictions are federal and
California. The Fund's federal and state income and federal excise tax returns
for tax years for which the applicable statutes of limitations have not expired
are subject to examination by the Internal Revenue Service and state departments
of revenue.

     DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS: The Fund expects to declare
dividends on a monthly basis to shareholders of Common Stock ("Shareholders").
Distributions to Shareholders are recorded on the ex-dividend date. Any net
realized short-term capital gains will be distributed to Shareholders at least
annually. Any net realized long-term capital gains may be distributed to
Shareholders at least annually or may be retained by the Fund as determined by
the Fund's Board of Directors. Capital gains retained by the Fund are subject to
tax at the capital gains corporate tax rate. Subject to the Fund qualifying as a
regulated investment company, any taxes paid by the Fund on such net realized
long-term capital gains may be used by the Fund's Shareholders as a credit
against their own tax liabilities. The Fund may pay distributions in excess of
the Fund's net investment company taxable income and this excess would be a
tax-free return of capital distributed from the Fund's assets.

     Income and capital gain distributions are determined and characterized in
accordance with income tax regulations which may differ from US GAAP. These
differences are primarily due to (1) differing treatments of income and gains on
various investment securities held by the Fund, including timing differences,
(2) the attribution of expenses against certain components of taxable investment
income, and (3) federal regulations requiring proportionate allocation of income
and gains to all classes of shareholders.

     Distributions from net realized gains for book purposes may include
short-term capital gains, which are included as ordinary income for tax
purposes, and may exclude amortization of premium on certain fixed income
securities, which are not reflected in ordinary income for tax purposes. The tax
character of distributions paid, including changes in accumulated undeclared
distributions to APS shareholders, during 2009 and 2008 was as follows:

     At November 30, 2009, the composition of the Fund's $32,900,766 accumulated
realized capital losses was $1,223,987, $694,286, $2,051,511, $15,168,592 and
$13,762,390 incurred in 2002, 2004, 2007, 2008 and 2009, respectively. These
losses may be carried forward and offset against any future capital gains
through 2010, 2012, 2015, 2016 and 2017, respectively.

     RECLASSIFICATION OF ACCOUNTS: During the year ended November 30, 2009,
reclassifications were made in the Fund's capital accounts to report these
balances on a tax basis, excluding temporary differences, as of November 30,
2009. Additional adjustments may be required in subsequent reporting periods.
These reclassifications have no impact on the net asset value of the Fund.

     The calculation of net investment income per share in the financial
highlights excludes these adjustments. Below are the reclassifications:

     EXCISE TAX: The Internal Revenue Code of 1986, as amended, imposes a 4%
nondeductible excise tax on the Fund to the extent the Fund does not distribute
by the end of any calendar year at least (1) 98% of the sum of its net
investment income for that year and its capital gains (both long-term and short-
term) for its fiscal year and (2) certain undistributed amounts from previous
years.

3.   INVESTMENT ADVISORY FEE, ADMINISTRATION FEE, TRANSFER AGENT FEE, CUSTODIAN
     FEE, DIRECTORS' FEES AND CHIEF COMPLIANCE OFFICER FEE

     Flaherty & Crumrine Incorporated (the "Adviser") serves as the Fund's
investment adviser. The Fund pays the Adviser a monthly fee at an annual rate of
0.625% of the value of the Fund's average monthly total managed assets up to
$100 million and 0.50% of the Fund's average monthly total managed assets of
$100 million or more. For purposes of calculating the fees payable to the
Adviser, Administrator and Custodian, the Fund's total managed assets means the
total assets of the Fund (including any assets attributable to the Fund's
preferred stock that may be outstanding or otherwise attributable to the use of
leverage) minus the sum of accrued liabilities (other than debt, if any,
representing financial leverage). For purposes of determining total managed
assets, the liquidation preference of any outstanding preferred shares issued by
the Fund is not treated as a liability.

     PNC Global Investment Servicing (U.S.) Inc. ("PNC") serves as the Fund's
Administrator. As Administrator, PNC calculates the net asset value of the
Fund's shares attributable to Common Stock and generally assists in all aspects
of the Fund's administration and operation. As compensation for PNC's services
as Administrator, the Fund pays PNC a monthly fee at an annual rate of 0.10% of
the first $200 million of the Fund's average weekly total managed assets, 0.04%
of the next $300 million of the Fund's average weekly total managed assets,
0.03% of the next $500 million of the Fund's average weekly total managed assets
and 0.02% on the Fund's average weekly total managed assets above $1 billion.

     PNC also serves as the Fund's Common Stock dividend-paying agent and
registrar (Transfer Agent). As compensation for PNC's services, the Fund pays
PNC a fee at an annual rate of 0.02% of the first $150 million of the Fund's
average weekly net assets attributable to Common Stock, 0.0075% of the next $350
million of the Fund's average weekly net assets attributable to Common Stock,
and 0.0025% of the Fund's average weekly net assets attributable to Common Stock
above $500 million, plus certain out of pocket expenses. For the purpose of
calculating such fee, the Fund's average weekly net assets attributable to
Common Stock are deemed to be the average weekly value of the Fund's total
assets minus the sum of the Fund's liabilities. For this calculation, the Fund's
liabilities are deemed to include the aggregate liquidation preference of any
outstanding preferred shares.

     PFPC Trust Company ("PFPC Trust") serves as the Fund's custodian. PFPC
Trust is an indirect subsidiary of PNC Financial Services. As compensation for
PFPC Trust's services as custodian, the Fund pays PFPC Trust a monthly fee at
the annual rate of 0.01% of the first $200 million of the Fund's average weekly
total managed assets, 0.008% of the next $300 million of the Fund's average
weekly total managed assets, 0.006% of the next $500 million of the Fund's
average weekly total managed assets and 0.005% of the Fund's average weekly
total managed assets above $1 billion.

     The Fund currently pays each Director who is not a director, officer or
employee of the Adviser a fee of $9,000 per annum, plus $500 for each in-person
meeting of the Board of Directors or any committee and $150 for each telephone
meeting. The Audit Committee Chairman receives an additional annual fee of
$2,500. The Fund also reimburses all Directors for travel and out-of-pocket
expenses incurred in connection with such meetings.

     The Fund currently pays the Adviser a fee of $37,500 per annum for Chief
Compliance Officer services and reimburses out-of-pocket expenses incurred in
connection with providing services in this role.

4.   PURCHASES AND SALES OF SECURITIES

     For the year ended November 30, 2009, the cost of purchases and proceeds
from sales of securities excluding short-term investments, aggregated
$77,640,304 and $68,620,583, respectively.

     At November 30, 2009, the aggregate cost of securities for federal income
tax purposes was $150,079,562, the aggregate gross unrealized appreciation for
all securities in which there is an excess of value over tax cost was
$12,670,891 and the aggregate gross unrealized depreciation for all securities
in which there is an excess of tax cost over value was $22,521,946.

5.   COMMON STOCK

     At November 30, 2009, 240,000,000 shares of $0.01 par value Common Stock
were authorized.

     Common Stock transactions were as follows:

6.   AUCTION PREFERRED STOCK (APS)

     The Fund's Articles of Incorporation authorize the issuance of up to
10,000,000 shares of $0.01 par value preferred stock. Prior to August 4, 2009,
the Fund had preferred stock issued in the form of APS. The APS was senior to
the Common Stock and resulted in the financial leveraging of the Common Stock.
As of August 4, 2009, the Fund redeemed and cancelled the last remaining shares
of APS and does not currently have any issued and outstanding shares of
preferred stock.

     The Fund repurchased APS shares in negotiated private transactions as
detailed in the table below. The difference between the purchase price and the
liquidation preference of $100,000 per share is included on the Statement of
Changes to Net Assets Available to Common Stock in this report as "Gain on
repurchase of Auction Preferred Stock". The gain resulting from both purchases
was $1.6 million.

                                       NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     The Fund redeemed APS shares as detailed in the table below. Shares were
redeemed at a redemption price equal to the liquidation preference of $100,000
per share, plus the amount of accumulated but unpaid dividends for each
redemption date, respectively. The Fund utilized proceeds from its debt facility
(See Note 7) for the last redemption. After these redemptions, borrowings from
its debt facility were the Fund's sole source of leverage.



REDEMPTION DATE     $ AMOUNT OF APS
-----------------   ---------------
                 
October 14, 2008      $10,000,000

March 10, 2009         13,000,000*
August 4, 2009         36,600,000


*    Shares were redeemed on the dates reflected; however, from the Fund's
     perspective, the November 20th redemption was effective as of October 24,
     2008 and the March 10th redemption was effective as of February 24, 2009.
     In both cases, the earlier effective date was due to the unconditional
     deposit of funds with the paying agent.

7.   COMMITTED FINANCING AGREEMENT

     The Fund entered into a committed financing agreement ("Financing
Agreement") on June 26, 2009 which allowed the Fund to borrow up to an initial
limit of $36.6 million on a secured basis. The primary use of the initial
proceeds was to redeem the outstanding shares of APS (See Note 6), although, the
Fund will use the borrowing facility in the normal course of business as
financial leverage. Such leveraging tends to magnify both the risks and
opportunities to Shareholders. On August 28, 2009, the Financing Agreement was
amended to allow for changes in the committed amount. As of November 30, 2009,
the committed amount, and amount borrowed under the Financing Agreement was $47
million.

     Under the terms of the Financing Agreement, the lender charges an
annualized rate of 1.00% on the undrawn (committed) balance, and Three-Month
London Interbank Offered Rate (LIBOR) - reset every three months - PLUS 1.10% on
the drawn (borrowed) balance. For the period beginning on August 4, 2009
(initial use of the facility) and ending on November 30, 2009, the daily
weighted average annualized interest rate on the drawn balance was 1.523% and
the average daily loan balance was $42,880,328. The Fund paid the lender an
arrangement fee (at the origination of the facility) equal to 0.50% of the
committed amount of $36.6 million. The arrangement fee will be amortized to
expense over a period of eighteen months, unless accelerated due to the
termination of the Financing Agreement. If the Fund elects to renew the
Financing Agreement, a renewal fee equal to 0.50% of the then-committed amount
shall be paid to the lender on each 540th calendar day following the date of the
original Financing Agreement. LIBOR rates may vary in a manner unrelated to the
income received on the Fund's assets, which could have either a beneficial or
detrimental impact on net investment income and gains available to Shareholders.

     The Fund is required to meet certain asset coverage requirements under the
Financing Agreement and under the 1940 Act. In accordance with the asset
coverage requirements, at least two-thirds of the Fund's assets are expected to
be pledged as collateral assuming the full committed amount is drawn. Securities
pledged as collateral are identified in the portfolio of investments. If the
Fund fails to meet


                                       33


Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

these requirements, or maintain other financial covenants required under the
Financing Agreement, the Fund may be required to repay immediately, in part or
in full, the amount borrowed under the Financing Agreement. Additionally,
failure to meet the foregoing requirements or covenants could restrict the
Fund's ability to pay dividends to Shareholders and could necessitate sales of
portfolio securities at inopportune times. The Financing Agreement has no stated
maturity, but may be terminated by either party without cause with six months'
advance notice.

8.   PORTFOLIO INVESTMENTS, CONCENTRATION AND INVESTMENT QUALITY

     The Fund invests primarily in a diversified portfolio of preferred
securities. This includes traditional preferred stocks eligible for the
inter-corporate dividends received deduction ("DRD") and fully taxable preferred
securities. Under normal market conditions, at least 80% of the value of the
Fund's net assets will be invested in preferred securities. Also, under normal
market conditions, the Fund invests at least 25% of its total assets in
securities of issuers in each of the utilities industry and financial services
sector. For purposes of the financial services sector concentration policy, a
company is within the financial services sector if it derives at least 50% of
its revenue from providing financial services. The Fund's portfolio may
therefore be subject to greater risk and market fluctuation than a portfolio of
securities representing a broader range of investment alternatives.

     The Fund may invest up to 25% of its assets at the time of purchase in
securities rated below investment grade. These securities must be rated at least
either "Ba3" by Moody's Investors Service, Inc. or "BB-" by Standard & Poor's
or, if unrated, judged to be comparable in quality by the Adviser, in any case,
at the time of purchase. However, these securities must be issued by an issuer
having a class of senior debt rated investment grade outstanding.

     The Fund may invest up to 15% of its assets in common stocks and, under
normal market conditions, up to 20% of its assets in debt securities. Certain of
its investments in hybrid, i.e., fully taxable, preferred securities will be
subject to the foregoing 20% limitation to the extent that, in the opinion of
the Adviser, such investments are deemed to be debt-like in key characteristics.
Typically, a security will not be considered debt-like (a) if an issuer can
defer payment of income for eighteen months or more without triggering an event
of default and (b) if such issue is a junior and fully subordinated liability of
an issuer or its ultimate guarantor.

     In addition to foreign money market securities, the Fund may invest up to
30% of its total assets in the securities of companies organized or having their
principal place of business outside the United States. All foreign securities
held by the Fund will be denominated in U.S. dollars.

9.   SPECIAL INVESTMENT TECHNIQUES

     The Fund may employ certain investment techniques in accordance with its
fundamental investment policies. These may include the use of when-issued and
delayed delivery transactions. Securities purchased or sold on a when-issued or
delayed delivery basis may be settled within 45 days after the date of the
transaction. Such transactions may expose the Fund to credit and market
valuation risk greater than that associated with regular trade settlement
procedures. The Fund may also enter into transactions, in accordance with its
investment policies, involving any or all of the following: short sales


                                       34



              Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated
                                       NOTES TO FINANCIAL STATEMENTS (CONTINUED)

of securities, purchases of securities on margin, futures contracts, interest
rate swaps, swap futures, options on futures contracts, options on securities,
swaptions and certain credit derivative transactions, including, but not limited
to, the purchase and sale of credit protection. As in the case of when-issued
securities, the use of over-the-counter derivatives, such as interest rate
swaps, swaptions, and credit default swaps may expose the Fund to greater
credit, operations, liquidity, and valuation risk than is the case with
regulated, exchange traded futures and options. These transactions are used for
hedging or other appropriate risk-management purposes, or, under certain other
circumstances, to increase return. No assurance can be given that such
transactions will achieve their desired purposes or will result in an overall
reduction of risk to the Fund.

10.  SECURITIES LENDING

     The Fund may lend up to 15% of its total assets (including the value of the
loan collateral) to certain qualified brokers in order to earn additional
income. The Fund receives compensation in the form of fees or interest earned on
the investment of any cash collateral received. The Fund also continues to
receive interest and dividends on the securities loaned. The Fund receives
collateral in the form of cash or securities with a market value at least equal
to the market value of the securities on loan, including accrued interest. In
the event of default or bankruptcy by the borrower, the Fund could experience
delays and costs in recovering the loaned securities or in gaining access to the
collateral. The Fund has the right under the lending agreement to recover the
securities from the borrower on demand. As of November 30, 2009, there were no
securities on loan by the Fund.

11.  SUBSEQUENT EVENTS

     Management has evaluated the impact of all subsequent events on the Fund
through January 21, 2010, the date the financial statements were issued, and has
determined that there were no subsequent events requiring recognition or
disclosure in the financial statements.

and significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of

SECTION 19 NOTICES

     Section 19 of the 1940 Act requires registered investment companies to
include a notice with the payment of a dividend if a portion of that dividend
may come from sources other than undistributed net income (other sources could
include realized gains from the sale of securities and non-taxable return of
capital). Copies of the Section 19 notices for the Fund are available on the
website at www.preferredincome.com.

     Form 1099-DIV will be sent to shareholders in January 2010 reporting the
amount and tax characterization of distributions for the 2009 calendar year.

DIVIDEND REINVESTMENT AND CASH PURCHASE PLAN

     Under the Fund's Dividend Reinvestment and Cash Purchase Plan (the "Plan"),
a shareholder whose Common Stock is registered in his or her own name will have
all distributions reinvested automatically by PNC as agent under the Plan,
unless the shareholder elects to receive cash. Distributions with respect to
shares registered in the name of a broker-dealer or other nominee (that is, in
"street name") may be reinvested by the broker or nominee in additional shares
under the Plan, but only if the service is provided by the broker or nominee,
unless the shareholder elects to receive distributions in cash. A shareholder
who holds Common Stock registered in the name of a broker or other nominee may
not be able to transfer the Common Stock to another broker or nominee and
continue to participate in the Plan. Investors who own Common Stock registered
in street name should consult their broker or nominee for details regarding
reinvestment.

     The number of shares of Common Stock distributed to participants in the
Plan in lieu of a cash dividend is determined in the following manner. Whenever
the market price per share of the Fund's Common Stock is equal to or exceeds the
net asset value per share on the valuation date, participants in the Plan will
be issued new shares valued at the higher of net asset value or 95% of the then
current market value. Otherwise, PNC will buy shares of the Fund's Common Stock
in the open market, on the New York Stock Exchange ("NYSE") or elsewhere, on or
shortly after the payment date of the dividend or distribution and continuing
until the ex-dividend date of the Fund's next distribution to holders of the
Common Stock or until it has expended for such purchases all of the cash that
would otherwise be payable to the participants. The number of purchased shares
that will then be credited to the participants' accounts will be based on the
average per share purchase price of the shares so purchased, including brokerage
commissions. If PNC commences purchases in the open market and the then current
market price of the shares (plus any estimated brokerage commissions)
subsequently exceeds their net asset value most recently determined before the
completion of the purchases, PNC will attempt to terminate purchases in the open
market and cause the Fund to issue the remaining dividend or distribution in
shares. In this case, the number of shares received by the participant will be
based on the weighted average of prices paid for shares purchased in the open
market and the price at which the Fund issues the remaining shares. These
remaining shares will be issued by the Fund at the higher of net asset value or
95% of the then current market value.

     Plan participants are not subject to any charge for reinvesting dividends
or capital gains distributions. Each Plan participant will, however, bear a
proportionate share of brokerage commissions incurred with respect to PNC's open
market purchases in connection with the reinvestment of dividends or capital
gains distributions. For the year ended November 30, 2009, $2,116 in brokerage
commissions were incurred.

     The automatic reinvestment of dividends and capital gains distributions
will not relieve Plan participants of any income tax that may be payable on the
dividends or capital gains distributions. A participant in the Plan will be
treated for Federal income tax purposes as having received, on the dividend
payment date, a dividend or distribution in an amount equal to the cash that the
participant could have received instead of shares.

                                  ADDITIONAL INFORMATION (UNAUDITED) (CONTINUED)

     In addition to acquiring shares of Common Stock through the reinvestment of
cash dividends and distributions, a shareholder may invest any further amounts
from $100 to $3,000 semi-annually at the then current market price in shares
purchased through the Plan. Such semi-annual investments are subject to any
brokerage commission charges incurred by PNC under the Plan.

     A shareholder whose Common Stock is registered in his or her own name may
terminate participation in the Plan at any time by notifying PNC in writing, by
completing the form on the back of the Plan account statement and forwarding it
to PNC, or by calling PNC directly. A termination will be effective immediately
if notice is received by PNC not less than 10 days before any dividend or
distribution record date. Otherwise, the termination will be effective, and only
with respect to any subsequent dividends or distributions, on the first day
after the dividend or distribution has been credited to the participant's
account in additional shares of the Fund. Upon termination and according to a
participant's instructions, PNC will either (a) issue certificates for the whole
shares credited to the shareholder's Plan account and a check representing any
fractional shares or (b) sell the shares in the market. Shareholders who hold
Common Stock registered in the name of a broker or other nominee should consult
their broker or nominee to terminate participation.

     The Plan is described in more detail in the Fund's Plan brochure.
Information concerning the Plan may be obtained from PNC at 1-800-331-1710.

ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END
     MANAGEMENT INVESTMENT COMPANIES.

The Proxy Voting Policies are attached herewith.

                  ADVISER PROXY VOTING POLICIES AND PROCEDURES

Flaherty & Crumrine Incorporated ("F&C") acts as discretionary investment
adviser for various clients, including the following six pooled investment
vehicles (the "Funds"):


                              
As adviser to the "U.S. Funds"   Flaherty & Crumrine Preferred Income Fund
                                 Flaherty & Crumrine Preferred Income Opportunity Fund
                                 Flaherty & Crumrine/Claymore Preferred Securities Income Fund
                                 Flaherty & Crumrine/Claymore Total Return Fund

As sub-adviser
to the "Canadian Fund"           Flaherty & Crumrine Investment Grade Fixed Income Fund


F&C's authority to vote proxies for its clients is established through the
delegation of discretionary authority under its investment advisory contracts
and the U.S. Funds have adopted these policies and procedures for themselves

PURPOSE

These policies and procedures are designed to satisfy F&C's duties of care and
loyalty to its clients with respect to monitoring corporate events and
exercising proxy authority in the best interests of such clients.

In connection with this objective, these policies and procedures are designed to
deal with potential complexities which may arise in cases where F&C's interests
conflict or appear to conflict with the interests of its clients.

These policies and procedures are also designed to communicate with clients the
methods and rationale whereby F&C exercises proxy voting authority.



This document is available to any client or Fund shareholder upon request and
F&C will make available to such clients and Fund shareholders the record of
F&C's votes promptly upon request and to the extent required by Federal law and
regulations.

FUNDAMENTAL STANDARD

F&C will be guided by the principle that, in those cases where it has proxy
voting authority, it will vote proxies, and take such other corporate actions,
consistent with the interest of its clients in a manner free of conflicts of
interest with the objective of client wealth maximization.

GENERAL

F&C has divided its discussion in this document into two major categories:
voting with respect to common stock and voting with respect to senior equity,
e.g., preferred stock and similar securities. In those events where F&C may have
to take action with respect to debt, such as in the case of amendments of
covenants or in the case of default, bankruptcy, reorganization, etc., F&C will
apply the same principles as would apply to common or preferred stock, MUTATIS
MUTANDIS.

These policies and procedures apply only where the client has granted
discretionary authority with respect to proxy voting. Where F&C does not have
authority, it will keep appropriate written records evidencing that such
discretionary authority has not been granted.

F&C may choose not to keep written copies of proxy materials that are subject to
SEC regulation and maintained in the SEC's EDGAR database. In other instances,
F&C will keep appropriate written records in its files or in reasonably
accessible storage.

Similarly, F&C will keep in its files, or reasonably accessible storage, work
papers and other materials that were significant to F&C in making a decision how
to vote.

For purposes of decision making, F&C will assume that each ballot for which it
casts votes is the only security of an issuer held by the client. Thus, when
casting votes where F&C may have discretionary authority with regard to several
different securities of the same issuer, it may vote securities "in favor" for
those securities or classes where F&C has determined the matter in question to
be beneficial while, at the same time, voting "against" for those securities or
classes where F&C has determined the matter to be adverse. Such cases
occasionally arise, for example, in those instances where a vote is required by
both common and preferred shareholders, voting as separate classes, for a change
in the terms regarding preferred stock issuance.

F&C will reach its voting decisions independently, after appropriate
investigation. It does not generally intend to delegate its decision making or
to rely on the recommendations of any third party, although it may take such
recommendations into consideration. F&C may consult with such other experts,
such as CPA's, investment bankers, attorneys, etc., as it regards necessary to
help it reach informed decisions.

Absent good reason to the contrary, F&C will generally give substantial weight
to management recommendations regarding voting. This is based on the view that
management is usually in the best position to know which corporate actions are
in the best interests of common shareholders as a whole.

With regard to those shareholder-originated proposals which are typically
described as "social, environmental, and corporate responsibility" matters, F&C
will typically give weight to management's recommendations and vote against such
shareholder proposals, particularly if the adoption of such proposals would
bring about burdens or costs not borne by those of the issuer's competitors.



In cases where the voting of proxies would not justify the time and costs
involved, F&C may refrain from voting. From the individual client's perspective,
this would most typically come about in the case of small holdings, such as
might arise in connection with spin-offs or other corporate reorganizations.
From the perspective of F&C's institutional clients, this envisions cases (1) as
more fully described below where preferred and common shareholders vote together
as a class or (2) other similar or analogous instances.

Ultimately, all voting decisions are made on a case-by-case basis, taking
relevant considerations into account.

VOTING OF COMMON STOCK PROXIES

F&C categorizes matters as either routine or non-routine, which definition may
or may not precisely conform to the definitions set forth by securities
exchanges or other bodies categorizing such matters. Routine matters would
include such things as the voting for directors and the ratification of auditors
and most shareholder proposals regarding social, environmental, and corporate
responsibility matters. Absent good reason to the contrary, F&C normally will
vote in favor of management's recommendations on these routine matters.

Non-routine matters might include, without limitation, such things as (1)
amendments to management incentive plans, (2) the authorization of additional
common or preferred stock, (3) initiation or termination of barriers to takeover
or acquisition, (4) mergers or acquisitions, (5) changes in the state of
incorporation, (6) corporate reorganizations, and (7) "contested" director
slates. In non-routine matters, F&C, as a matter of policy, will attempt to be
generally familiar with the questions at issue. This will include, without
limitation, studying news in the popular press, regulatory filings, and
competing proxy solicitation materials, if any. Non-routine matters will be
voted on a case-by-case basis, given the complexity of many of these issues.

VOTING OF PREFERRED STOCK PROXIES

Preferred stock, which is defined to include any form of equity senior to common
stock, generally has voting rights only in the event that the issuer has not
made timely payments of income and principal to shareholders or in the event
that a corporation desires to effectuate some change in its articles of
incorporation which might modify the rights of preferred stockholders. These are
non-routine in both form and substance.

In the case of non-routine matters having to do with the modification of the
rights or protections accorded preferred stock shareholders, F&C will attempt,
wherever possible, to assess the costs and benefits of such modifications and
will vote in favor of such modifications only if they are in the bests interests
of preferred shareholders or if the issuer has offered sufficient compensation
to preferred stock shareholders to offset the reasonably foreseeable adverse
consequences of such modifications. A similar type of analysis would be made in
the case where preferred shares, as a class, are entitled to vote on a merger or
other substantial transaction.

In the case of the election of directors when timely payments to preferred
shareholders have not been made ("contingent voting"), F&C will cast its votes
on a case-by-case basis after investigation of the qualifications and
independence of the persons standing for election.

Routine matters regarding preferred stock are the exception, rather than the
rule, and typically arise when the preferred and common shareholders vote
together as a class on such matters as election of directors. F&C will vote on a
case-by-case basis, reflecting the principles set forth elsewhere in this



document. However, in those instances (1) where the common shares of an issuer
are held by a parent company and (2) where, because of that, the election
outcome is not in doubt, F&C does not intend to vote such proxies since the time
and costs would outweigh the benefits.

ACTUAL AND APPARENT CONFLICTS OF INTEREST

Potential conflicts of interest between F&C and F&C's clients may arise when
F&C's relationships with an issuer or with a related third party conflict or
appear to conflict with the best interests of F&C's clients.

F&C will indicate in its voting records available to clients whether or not a
material conflict exists or appears to exist. In addition, F&C will communicate
with the client (which means the independent Directors or Director(s) they may
so designate in the case of the U.S. Funds and the investment adviser in the
case of the Canadian Funds) in instances when a material conflict of interest
may be apparent. F&C must describe the conflict to the client and state F&C's
voting recommendation and the basis therefor. If the client considers there to
be a reasonable basis for the proposed vote notwithstanding the conflict or, in
the case of the Funds, that the recommendation was not affected by the conflict
(without considering the merits of the proposal), F&C will vote in accordance
with the recommendation it had made to the client.

In all such instances, F&C will keep reasonable documentation supporting its
voting decisions and/or recommendations to clients.

AMENDMENT OF THE POLICIES AND PROCEDURES

These policies and procedures may be modified at any time by action of the Board
of Directors of F&C but will not become effective, in the case of the U.S.
Funds, unless they are approved by majority vote of the non-interested directors
of the U.S. Funds. Any such modifications will be sent to F&C's clients by mail
and/or other electronic means in a timely manner. These policies and procedures,
and any amendments hereto, will be posted on the U.S. Funds' websites and will
be disclosed in reports to shareholders as required by law.

ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

The following paragraphs provide certain information with respect to the
portfolio managers of the Fund and the material conflicts of interest that may
arise in connection with their management of the investments of the Fund, on the
one hand, and the investments of other client accounts for which they have
responsibility, on the other hand. Certain other potential conflicts of interest
with respect to personal trading and proxy voting are discussed above under
"Item 2 - Codes of Ethics" and "Item 7 - Proxy Voting Policies."

POTENTIAL CONFLICTS OF INTEREST

In addition to the Fund, the Portfolio Managers jointly manage accounts for
three other closed-end funds, one Canadian fund and other institutional clients.
As a result, potential conflicts of interest may arise as follows:

     -    ALLOCATION OF LIMITED TIME AND ATTENTION. The Portfolio Managers may
          devote unequal time and attention to the management of all accounts.
          As a result, the Portfolio Managers may not be able to formulate as
          complete a strategy or identify equally attractive investment
          opportunities for each of those accounts as might be the case if they
          were to devote substantially more attention to the management of one
          account.

     -    ALLOCATION OF LIMITED INVESTMENT OPPORTUNITIES. If the Portfolio
          Managers identify an investment opportunity that may be suitable for
          multiple accounts, the Fund may not be able to take full advantage of
          that opportunity because the opportunity may need to be allocated
          among other accounts.

     -    PURSUIT OF DIFFERING STRATEGIES. At times, the Portfolio Managers may
          determine that an investment opportunity may be appropriate for only
          some accounts or may decide that certain of these accounts should take
          differing positions (i.e., may buy or sell the particular security at
          different times or the same time or in differing amounts) with respect
          to a particular security. In these cases, the Portfolio Manager may
          place separate transactions for one or more accounts which may affect
          the market price of the security or the execution of the transaction,
          or both, to the detriment of one or more other accounts.

     -    VARIATION IN COMPENSATION. A conflict of interest may arise where the
          financial or other benefits available to the Portfolio Manager differ
          among accounts. While the Adviser only charges fees based on assets
          under management and does not receive a performance fee from any of
          its accounts, and while it strives to maintain uniform fee schedules,
          it does have different fee schedules based on the differing advisory
          services required by some accounts. Consequently, though the
          differences in such fee rates are slight, the Portfolio Managers may
          be motivated to favor certain accounts over others. In addition, the
          desire to maintain assets under management or to derive other rewards,
          financial or otherwise, could



          influence the Portfolio Managers in affording preferential treatment
          to those accounts that could most significantly benefit the Adviser.

The Adviser and the Fund have adopted compliance policies and procedures that
are designed to address the various conflicts of interest that may arise for the
Adviser and its staff members. However, there is no guarantee that such policies
and procedures will be able to detect and prevent every situation in which an
actual or potential conflict may arise.

(A)(3) PORTFOLIO MANAGER COMPENSATION

Compensation is paid solely by the Adviser. Each Portfolio Manager receives the
same fixed salary. In addition, each Portfolio Manager receives a bonus based on
peer reviews of his performance and the total net investment advisory fees
received by Flaherty & Crumrine (which are in turn based on the value of its
assets under management). The Portfolio Managers do not receive deferred
compensation, but participate in a profit-sharing plan available to all
employees of the Adviser; amounts are determined as a percentage of the
employee's eligible compensation for a calendar year based on IRS limitations.
Each Portfolio Manager is also a shareholder of Flaherty & Crumrine and receives
quarterly dividends based on his equity interest in the company.
