FLAHERTY & CRUMRINE PREFERRED INCOME OPPORTUNITY FUND

To the Shareholders of Flaherty & Crumrine Preferred Income Opportunity Fund (“PFO”):

Your Fund performed well during its third fiscal quarter¹, delivering +3.1% total return on net asset value². For the first nine months of fiscal 2014, the Fund’s return on NAV was an impressive +15.3%. While third quarter market performance was -3.5%, year-to-date market performance was +16.7% at August 31^st.

U.S. economic growth appears to be running around 3% currently, after averaging just 1.3% in 2014’s first half. Job growth is up, unemployment is down and inflation remains low. The Fed is not filling its monetary punch bowl as quickly as before, but, while it’s always hard to predict what the Fed will do, it probably won’t start to raise short-term interest rates until mid-2015 or later. In contrast, economic growth abroad has slowed, with most developed countries trailing the U.S. recovery and monetary policy in many of those countries is easing further.

Although long-term interest rates in the U.S. will probably rise modestly over coming quarters, we think any upward movement will be limited by moderate GDP growth and strong investor demand for yield. Credit conditions continue to improve for most issuers of preferred securities, as earnings remain healthy and companies continue to build capital. With this backdrop, we believe prospective returns remain attractive for long-term investors.

The Fund’s portfolio benefited from small declines in intermediate and long-term interest rates during the quarter, as well as on-going demand for higher yields of preferred securities. Supply of new issues remains steady—a key measure of market health. From December 2013 through September 2014, U.S. and foreign companies issued 103 new securities in the United States, raising just under $64 billion. Over the same period, issuers redeemed 67 preferred securities totaling $25 billion.

New issue supply was dominated by banks tailoring their capital to meet new regulatory requirements. Large U.S. banks (those deemed to be a systemically important financial institution, or “SIFI”) have issued traditional non-cumulative perpetual preferred stock. Non-U.S. SIFI banks are utilizing a preferred stock variation termed Contingent Convertible Securities, or CoCos. As you know from prior letters, the Fund has not yet purchased any CoCos, but we continue to evaluate them as potential investments.

With foreign economies lagging recovery in the U.S. and foreign banks issuing securities we have not yet been inclined to buy, the portion of the portfolio invested in foreign securities has drifted lower this fiscal year. Through September 30^th, this portion declined from 25.8% of the portfolio to 17.8%. We anticipate this rate could fall further through more issuer redemptions.

As we discussed last quarter, another portfolio trend is a continued shift to “fixed-to-float” securities. These have coupons that are fixed for an initial period, typically five or ten years. Afterwards, coupons float based on a formula set at issuance. Prices on floating rate issues typically are less sensitive to changes in benchmark interest rates; this effect has spilled over to fixed-to-float preferred securities as well. If long-term interest rates begin to rise, as we expect they will eventually, these securities should tend to outperform issues with fixed-for-life coupons, all other things being equal. This fiscal year through September 30^th, the

²	Following methodology required by the SEC, total return assumes dividend reinvestment and includes income and principal change, plus the impact of the Fund’s leverage and expenses.

portion of the portfolio in this structure increased from 45.0% to 50.9%. We continue to look for opportunities to add fixed-to-float holdings. Although these issues yield a bit less than many fixed-for-life securities, and thus may reduce portfolio income at the margin, we believe owning fixed-to-float securities is prudent and consistent with our interest-rate outlook.

As always, we encourage you to visit the Fund’s website, www.preferredincome.com, for current information on preferred-securities markets, the Fund and the broader economy.

Sincerely,

The Flaherty & Crumrine Portfolio Management Team:

NOTES TO FINANCIAL STATEMENTS (Unaudited)

1.	Aggregate Information for Federal Income Tax Purposes

At August 31, 2014, the aggregate cost of securities for federal income tax purposes was $202,598,681, the aggregate gross unrealized appreciation for all securities in which there was an excess of value over tax cost was $18,631,195 and the aggregate gross unrealized depreciation for all securities in which there was an excess of tax cost over value was $10,067,773.

2.	Additional Accounting Standards

Fair Value Measurements: The Fund has analyzed all existing investments to determine the significance and character of all inputs to their fair value determination. The levels of fair value inputs used to measure the Fund’s investments are characterized into a fair value hierarchy. Where inputs for an asset or liability fall into more than one level in the fair value hierarchy, the investment is classified in its entirety based on the lowest level input that is significant to that investment’s valuation. The three levels of the fair value hierarchy are described 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. Transfers in and out of levels are recognized at market value at the end of the period. A summary of the inputs used to value the Fund’s investments as of August 31, 2014 is as follows:


	Total Value at August 31, 2014		Level 1 Quoted Price		Level 2 Significant Observable Inputs		Level 3 Significant Unobservable Inputs

Total Investments	$	211,162,103	$	140,450,255	$	70,705,098	$	6,750

During the reporting period, there were no transfers into Level 1 from Level 2 or into Level 2 from Level 1.

The fair values of the Fund’s investments are generally based on market information and quotes received from brokers or independent pricing services—approved by the Board of Directors and unaffiliated with the Adviser. To assess the continuing appropriateness of security valuations, management, in consultation with the Adviser, regularly compares current prices to prior prices, prices across comparable securities, actual sale prices for securities in the Fund’s portfolio, and market information obtained by the Adviser as a function of being an active market participant.

Securities with quotes that are based on actual trades or actionable bids and offers with a sufficient level of activity on or near the measurement date are classified as Level 1. Securities that are priced using quotes derived from implied values, indicative bids and offers, or a limited number of actual trades—or the same information for securities that are similar in many respects to those being valued—are classified as Level 2. If market information is not available for securities being valued, or materially-comparable securities, then those securities are classified as Level 3. In considering market information, management evaluates changes in liquidity, willingness of a broker to execute at the quoted price, the depth and consistency of prices from pricing services, and the existence of observable trades in the market.

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


			Preferred Securities
	Total Investments		Banking
Balance as of 11/30/13	$	6,750	$	6,750
Accrued discounts/premiums		—		—
Realized gain/(loss)		—		—
Change in unrealized appreciation/(depreciation)		—		—
Purchases		—		—
Sales		—		—
Transfer in		—		—
Transfer out		—		—
Balance as of 08/31/14	$	6,750	$	6,750

For the nine months ended August 31, 2014, total change in unrealized gain/(loss) on Level 3 securities still held at period-end and included in the change in net assets was $0.

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated

NOTES TO FINANCIAL STATEMENTS (Unaudited) (Continued)

The following table summarizes the valuation techniques used and unobservable inputs developed to determine the fair value of Level 3 investments:


Category	Fair Value at 08/31/14		Valuation Technique	Unobservable Input	Input Range (Wgt Avg)
Preferred Securities
Banking	$	6,750	Bankruptcy recovery	Credit/Structure-specific recovery	0.00% - 0.50% (0.15%)

The significant unobservable inputs used in the fair value measurement technique for bankruptcy recovery are based on recovery analysis that is specific to the security being valued, including the level of subordination and structural features of the security, and the current status of any bankruptcy or liquidation proceedings. Observable market trades in bankruptcy claims are utilized by management, when available, to assess the appropriateness of valuations, although the frequency of trading depends on the specific credit and seniority of the claim. Expected recoveries in bankruptcy by security type and industry do not tend to deviate much from historical recovery rates, which are very low (sometimes zero) for preferred securities and more moderate for senior debt. Significant changes in these inputs would result in a significantly higher or lower fair value measurement.
