Wells Fargo Advantage Funds

Fixed-income markets shifted significantly during the period as economic optimism surged in the opening months of 2013, spurring a rally in equities; a rise in U.S. Treasury yields; and, ultimately, significant outperformance from high-yield bonds.

Dear Valued Shareholder:

We are pleased to offer you this semi-annual report for the Wells Fargo Advantage Income Opportunities Fund for the six-month period that ended October 31, 2013. Fixed-income markets shifted significantly during the period as economic optimism surged in the opening months of 2013, spurring a rally in equities; a rise in U.S. Treasury yields; and, ultimately, significant outperformance from high-yield bonds. Most investment-grade bond sectors experienced price declines along with rising Treasury yields during much of 2013. However, below-investment-grade securities tended to perform better as their higher-yield spreads cushioned some of the yield increases from the Treasury markets before rallying later in the period. On the whole, U.S. high-yield corporate securities generated strong positive returns during the period, overcoming significant price corrections in June 2013.

The return of economic optimism in 2013 led to declines in bond prices as yields rose higher.

Before the period began, U.S. Treasury yields began to rise higher on optimistic expectations for a strengthening U.S. economy during the opening months of 2013. Consequently, fixed-income security yields shifted higher and prices declined across much of the U.S. investment-grade bond sectors, most notably in the longer-maturity ranges, as investors began to reprice bond yields for potential interest-rate increases in upcoming years. Nonetheless, high-yield securities generally withstood the rate shocks and continued to provide positive returns.

These trends continued into May 2013 which was rattled by geopolitical events, domestic terrorism in Boston, and uncertain global economic conditions. U.S. Treasury prices increased sharply, temporarily erasing all of the price losses endured in January 2013 and, in fact, crossing over into positive gains. Meanwhile, U.S. high-yield bonds continued to generate positive returns for the month.

Unfortunately, this streak for high yield would end in May 2013 as a massive rally in the U.S. equity markets erupted, driving U.S. Treasury prices down and this time dragging with them the high-yield bond market. These market moves resulted in the largest monthly losses across the investment-grade bond markets in nearly five years, while high yield saw its first monthly decline in just over a year.

The depreciating trends for bonds deepened in mid-June 2013 on comments from Federal Reserve (Fed) Chairman Bernanke that tapering of the Fed’s bond-buying programs could begin later in the year and that the programs may end completely around mid-2014. For the last two weeks of June 2013, that debate appeared to play out daily, as volatility buffeted both the equity and bond markets, finally capitulating to yet another sustained rally in equities and a modest retreat in bond prices. Both investment-grade bonds and high-yield bonds posted their worst monthly returns of the year in June 2013—investment-grade securities had their largest quarterly decline in nine years during the second quarter and high yield had its worst quarter since 2011.

In July and August 2013, equity exuberance quieted a bit, and fixed-income markets stabilized. Returns were more mixed, with slightly negative returns in the highest-quality securities to modestly positive in the lower credit tiers. In September and October 2013, investment-grade and high-yield bond markets began generating positive returns yet again, as the Fed backtracked on its intentions to taper quantitative easing, postponing it until 2014 at the

Letter to shareholders (unaudited) Wells Fargo Advantage Income Opportunities Fund 3

earliest. Bond markets rallied on the news through the end of the period, and the high-yield bond markets significantly outperformed the investment-grade markets.

On the whole, strong returns in high yield during the final months of the period overcame the sharp price declines during May, June, and August 2013, culminating in positive returns across the high-yield market during the full period. Thus, the theme for the period was a persistent increase in U.S. Treasury yields that pressured fixed-income security prices before relaxing in September and October 2013. High-yield securities benefited from yield cushioning during the yield rises before rallying on strong investor appetite for equity-correlated returns.

Don’t let short-term uncertainty derail long-term investment goals.

Periods of uncertainty can present challenges, but experience has taught us that maintaining long-term investment goals can be an effective way to plan for the future. Although diversification cannot guarantee an investment profit or prevent losses, we believe it can be an effective way to manage investment risk and potentially smooth out overall portfolio performance. We encourage investors to know their investments and to understand that appropriate levels of risk-taking may unlock opportunities.

Thank you for choosing to invest with Wells Fargo Advantage Funds. We appreciate your confidence in us and remain committed to helping you meet your financial needs.

Figures quoted represent past performance, which is no guarantee of future results, and do not reflect taxes that a shareholder may pay on fund distributions or the sales of fund shares. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when sold, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data quoted, which assumes the reinvestment of dividends and capital gains. Performance figures of the Fund do not reflect brokerage commissions that a shareholder would pay on the purchase and sale of shares. If taxes and such brokerage commissions had been reflected, performance would have been lower. To obtain performance information current to the most recent month-end, please call 1-800-222-8222.

The Adviser has committed through February 25, 2014, to waive fees and/or reimburse expenses to the extent necessary to limit the Fund’s borrowing expenses to an amount that is 0.05% lower than what the borrowing expenses would have been if the Fund had not redeemed its Auction Market Preferred Shares. The Fund’s gross and net expense ratios for the six months ended October 31, 2013, were 1.27% and 1.02%, respectively, which includes 0.07% of interest expense. Without this waiver and/or reimbursement, the Fund’s returns would have been lower.

Comparison of NAV vs. market value²

The Fund is leveraged through a secured debt borrowing facility and also may incur leverage by issuing preferred shares in the future. The use of leverage results in certain risks including, among others, the likelihood of greater volatility of net asset value and the market price of common shares. Derivatives involve additional risks including interest rate risk, credit risk, the risk of improper valuation, and the risk of non-correlation to the relevant instruments that they are designed to hedge or to closely track. Bond values fluctuate in response to the financial condition of individual issuers, general market and economic conditions, and changes in interest rates. In general, when interest rates rise, bond values fall and investors may lose principal value. High-yield securities have a greater risk of default and tend to be more volatile than higher-rated debt securities.

1. Total returns based on market value are calculated assuming a purchase of common stock on the first day and a sale on the last day of the period reported. Total returns based on NAV are calculated based on the NAV at the beginning of the period and end of the period. Dividends and distributions, if any, are assumed for the purposes of these calculations to be reinvested at prices obtained under the Fund’s Automatic Dividend Reinvestment Plan.

2. This chart does not reflect any brokerage commissions on the purchase and sale of the Fund’s common stock. Dividends and distributions have the effect of reducing the Fund’s NAV.

MANAGER’S DISCUSSION

The Fund’s return based on market value was -4.29% during the 6 months ended October 31, 2013. During the same period, the Fund’s returns based on NAV was 7.90%.

Overview

Fixed-income markets generally struggled as Treasury yields rose in anticipation of a reduction in the extraordinarily loose Federal Reserve (Fed) policies. Expectations that tapering in the Fed’s monthly $85 billion asset purchase program would cause rates to rise led to investors selling rate-sensitive bonds. The high-yield market was initially weak yet managed to generate positive returns in spite of the rate volatility with credit spreads declining during the period. Ultimately, the Fed surprised the markets by postponing the tapering, resulting in a strong rally across all asset classes, including high-yield bonds in the last few months of the period. Although the Fed’s decision was based on weaker-than-hoped-for economic data, the continuation of a low-interest-rate environment spurred investor confidence and provided support to the market.

Credit quality⁴ as of October 31, 2013

Contributors to performance

The Fund benefited from the continuation of accommodative monetary policy. The interest earned on higher yields combined with a decline in spreads helped offset market shifts to higher interest rates. Compared with the broad high-yield market, the Fund’s lower exposure to interest-rate sensitivity was a positive contributor to performance. A number of well-performing securities and a significant allocation to the information technology sector also aided performance.

Detractors to performance

The Fund continued to be positioned conservatively with less higher-yielding and more higher-quality issues than the broad high-yield market. Although the market was volatile during the period, the volatility was almost entirely due to rising interest rates. Credit continued to outperform with lower-quality securities outperforming amid a market

that continues to benefit from the Fed-induced low interest rates. In addition, Fund holdings within the pipelines and electric utilities sectors detracted from performance due to the impact from low natural gas prices.

3. The ten largest holdings are calculated based on the value of the securities divided by total net assets of the Fund. Holdings are subject to change and may have changed since the date specified.

4. Credit quality is subject to change and is calculated based on the total market value of bonds held by the Fund. The ratings indicated are from Standard & Poor’s, Moody’s Investors Service, and/or Fitch Ratings Ltd. Credit Quality Ratings. Credit quality ratings apply to the underlying holdings of the Fund and not the Fund itself. Standard & Poor’s rates the creditworthiness of bonds on a scale of AAA (highest) to D (lowest). Ratings from A to CCC may be modified by the addition of a plus (+) or minus (–) sign to show relative standing within the rating categories. Standard & Poor’s rates the creditworthiness of short-term notes from SP-1 (highest) to SP-3 (lowest). Moody’s rates the creditworthiness of bonds on a scale of Aaa (highest) to C (lowest). Ratings Aa to B may be modified by the addition of a number 1 (highest) to 3 (lowest) to show relative standing within the ratings categories. Moody’s rates the creditworthiness of short-term U.S. tax-exempt municipal securities from MIG 1/VMIG 1 (highest) to SG (lowest). Fitch rates the creditworthiness of bonds on a scale of AAA (highest) to D (lowest). If a security was rated by all three rating agencies, the middle rating was utilized. If rated by two of three rating agencies, the lower rating was utilized and if rated by one of the agencies that rating was utilized. We generally define higher quality bonds as bonds that have a rating of BBB/Baa and above and lower quality bonds as bonds with a rating below BBB/Baa.

Effective maturity distribution⁵ as of October 31, 2013

Management outlook

The Fund’s focus is on bottom-up security selection of bonds issued by companies with high intrinsic value, which, in our view, limits downside risk. Much of the high-yield market performance has been driven by the extraordinarily low interest rates, which allow highly indebted and highly leveraged companies to meet interest expense and term out maturities. The Fund continues to avoid companies that rely on such conditions to persist. As a result of the strategy of avoiding uncompensated risk, the Fund maintains its

lower-volatility profile. We do not feel it is prudent to stretch for yield in the current environment because of the relatively low compensation for taking incremental risk. That said, conditions are quite benign for the high-yield market, with the bulk of issuers enjoying high interest coverage ratios (ability to generate sufficient cash to meet interest expense) and low near-term maturities. We believe default rates may remain well below historical averages and high yield may continue to outperform rate-sensitive fixed-income markets.

5. Effective maturity distribution is subject to change and are calculated based on the total long-term investments of the Fund.

24 Wells Fargo Advantage Income Opportunities Fund Notes to financial statements (unaudited)

1. ORGANIZATION

Wells Fargo Advantage Income Opportunities Fund (the “Fund”) was organized as a statutory trust under the laws of the state of Delaware on December 3, 2002 and is registered as a diversified closed-end management investment company under the Investment Company Act of 1940, as amended.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time).

Fixed income securities acquired with maturities exceeding 60 days are valued based on evaluated bid prices provided by an independent pricing service which may utilize both transaction data and market information such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data. If prices are not available from the independent pricing service or prices received are deemed not representative of market value, values will be obtained from an independent broker-dealer or otherwise determined based on the Fund’s Valuation Procedures.

Short-term securities, with maturities of 60 days or less at time of purchase, generally are valued at amortized cost which approximates fair value. The amortized cost method involves valuing a security at its cost, plus accretion of discount or minus amortization of premium over the period until maturity.

Equity securities that are listed on a foreign or domestic exchange or market are valued at the official closing price or, if none, the last sales price. If no sale occurs on the primary exchange or market for the security that day, the prior day’s price will be deemed “stale” and fair values will be determined in accordance with the Fund’s Valuation Procedures.

Investments in registered open-end investment companies are valued at net asset value.

Investments which are not valued using any of the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Fund. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Management Valuation Team of Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Management Valuation Team which may include items for ratification.

Valuations of fair valued securities are compared to the next actual sales price when available, or other appropriate market values, to assess the continued appropriateness of the fair valuation methodologies used. These securities are fair valued on a day-to-day basis, taking into consideration changes to appropriate market information and any significant changes to the inputs considered in the valuation process until there is a readily available price provided on an exchange or by an independent pricing service. Valuations received from an independent pricing service or independent broker-dealer quotes are periodically validated by comparisons to most recent trades and valuations provided by other independent pricing services in addition to the review of prices by the adviser and/or subadviser. Unobservable inputs used in determining fair valuations are identified based on the type of security, taking into consideration factors utilized by market participants in valuing the investment, knowledge about the issuer and the current market environment.

When-issued transactions

The Fund may purchase securities on a forward commitment or when-issued basis. The Fund records a when-issued transaction on the trade date and will segregate assets in an amount at least equal in value to the Fund’s commitment to purchase when-issued securities. Securities purchased on a when-issued basis are marked-to-market daily and the Fund begins earning interest on the settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

Notes to financial statements (unaudited) Wells Fargo Advantage Income Opportunities Fund 25

Term loans

The Fund may invest in term loans. The Fund begins earning interest when the loans are funded. The loans pay interest at rates which are periodically reset by reference to a base lending rate plus a spread. The Fund assumes the credit risk of the borrower and there could be potential loss to the Fund in the event of default by the borrower.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Interest income is accrued daily and bond discounts are accreted and premiums are amortized daily based on the effective interest method. To the extent debt obligations are placed on non-accrual status, any related interest income may be reduced by writing off interest receivables when the collection of all or a portion of interest has become doubtful based on consistently applied procedures. If the issuer subsequently resumes interest payments or when the collectability of interest is reasonably assured, the debt obligation is removed from non-accrual status.

Dividend income is recognized on the ex-dividend date.

Distributions to shareholders

Distributions to shareholders from net investment income and net realized gains, if any, are recorded on the ex-dividend date. Such distributions are determined in conformity with federal income tax regulations, which may differ in amount or character from net investment income and realized gains recognized for purposes of U.S. generally accepted accounting principles.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of April 30, 2013, capital loss carryforwards available to offset future net realized capital gains were as follows through the indicated expiration dates:

2015	2016		2017		2018
$1,830,407	$	15,525,027	$	130,598,584	$	155,329,141

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Fund’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to significant unobservable inputs (Level 3). The Fund’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follow

n Level 1 – quoted prices in active markets for identical securities

n Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, use of amortized cost, etc.)

n Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

26 Wells Fargo Advantage Income Opportunities Fund Notes to financial statements (unaudited)

As of October 31, 2013, the inputs used in valuing investments in securities were as follows:

Investments in securities	Quoted prices (Level 1)		Other significant observable inputs (Level 2)		Significant unobservable inputs (Level 3)		Total

Transfers in and transfers out are recognized at the end of the reporting period. For the six months ended October 31, 2013, the Fund did not have any transfers into/out of Level 1 or Level 2.

The following is a reconciliation of assets in which significant unobservable inputs (Level 3) were used in determining fair value:

	Common stocks			Term loans			Total
Balance as of April 30, 2013	$	2,149		$	20,331,214		$	20,333,363
Accrued discounts (premiums)		0			8,053			8,053
Realized gains (losses)		0			(2,524	)		(2,524	)
Change in unrealized gains (losses)		(2,149	)		(689,881	)		(692,030	)

Change in unrealized gains (losses) relating to securities still held at October 31, 2013	$	(2,149	)	$	(604,345	)	$	(606,494	)

The investment types categorized above were valued using indicative broker quotes and are therefore considered Level 3 inputs.

Quantitative unobservable inputs used by the brokers are often proprietary and not provided to the Fund and therefore the disclosure that would address these inputs is not included above.

4. TRANSACTIONS WITH AFFILIATES AND OTHER EXPENSES

Advisory fee

Funds Management, an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the adviser to the Fund and is entitled to receive a fee at an annual rate of 0.60% of the Fund’s average daily total assets. Total assets consist of the net assets of the Fund plus borrowings or other leverage for investment purposes to the extent excluded in calculating net assets. Funds Management has committed through February 25, 2014, to waive fees and/or reimburse expenses to the extent necessary to limit the Fund’s borrowing expenses to an amount that is 0.05% lower than what the borrowing expenses would have been if the Fund had not redeemed its Auction Market Preferred Shares (“Preferred Shares”). Funds Management contractually waived its advisory fee in the amount of $881,937 for the six months ended October 31, 2013.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Fund. The fee for subadvisory services is borne by Funds Management. Wells Capital Management Incorporated, an affiliate of Funds Management and an indirect, wholly owned subsidiary of Wells Fargo, is the subadviser to the Fund and is entitled to receive a fee from Funds Management at an annual rate of 0.40% of the Fund’s average daily total assets.

Notes to financial statements (unaudited) Wells Fargo Advantage Income Opportunities Fund 27

Administration fee

Funds Management also serves as the administrator to the Fund providing the Fund with a wide range of administrative services necessary to the operation of the Fund. Funds Management is entitled to receive an annual administration fee from the Fund equal to 0.05% of the Fund’s average daily total assets.

5. CAPITAL SHARE TRANSACTIONS

The Fund has authorized capital of 100,000,000 shares with no par value. For the six months ended October 31, 2013, and year ended April 30, 2013, the Fund issued 15,971 and 241,079 shares, respectively.

The Fund no longer has any Preferred Shares outstanding.

6. BORROWINGS

The Fund has borrowed approximately $230 million through a secured debt financing agreement administered by a major financial institution (the “Facility”). The Facility has a commitment amount of $230 million which expires on February 24, 2014, at which point it may be renegotiated and potentially renewed for another one-year term. At October 31, 2013, the Fund had secured borrowings outstanding in the amount of $230,211,266 (including accrued interest and usage and commitment fees payable).

The Fund’s borrowings under the Facility are generally charged interest at a rate based on the rates of the commercial paper notes issued to fund the Fund’s borrowings or at the London Interbank Offered Rate (LIBOR) plus 1.0%. During the six months ended October 31, 2013, an effective interest rate of 0.21% was incurred on the borrowings. Interest expense of $243,915, representing 0.07% of the Fund’s average daily net assets, was incurred during the six months ended October 31, 2013.

The Fund has pledged all of its assets to secure the borrowings and currently pays, on a monthly basis, a usage fee at an annual rate of 0.40% of the daily average outstanding principal amount of borrowings and commitment fee at an annual rate of 0.40% of the product of (i) the daily average outstanding principal amount of borrowings and (ii) 1.02. The secured borrowing fees on the Statement of Operations of $1,017,509 represents the usage fee, commitment fee and structuring fees. For the six months ended October 31, 2013, the Fund paid structuring fees in the amount of $67,660.

7. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the six months ended October 31, 2013 were $190,729,310 and $149,548,464, respectively.

As of October 31, 2013, the Fund had unfunded term loan commitments of $19,730,700.

8. INDEMNIFICATION

Under the Fund’s organizational documents, the officers and directors are indemnified against certain liabilities that may arise out of performance of their duties to the Fund. Additionally, in the normal course of business, the Fund may enter into contracts with service providers that contain a variety of indemnification clauses. The Fund’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

9. SUBSEQUENT DISTRIBUTIONS

The Fund declared the following distributions to common shareholders:

Declaration date	Record date	Payable date	Per share amount
October 25, 2013	November 14, 2013	December 2, 2013	$0.068
November 15, 2013	December 16, 2013	January 2, 2014	0.068

These distributions are not reflected in the accompanying financial statements. The final determination of the source of all distributions is subject to change and made after the Fund’s tax year-end.

Automatic dividend reinvestment plan Wells Fargo Advantage Income Opportunities Fund 31

AUTOMATIC DIVIDEND REINVESTMENT PLAN

All common shareholders are eligible to participate in the Automatic Dividend Reinvestment Plan (“the Plan”). Pursuant to the Plan, unless a common shareholder is ineligible or elects otherwise, all cash dividends and capital gains distributions are automatically reinvested by Computershare Trust Company, N.A., as agent for shareholders in administering the Plan (“Plan Agent”), in additional common shares of the Fund. Whenever the Fund declares an ordinary income dividend or a capital gain dividend (collectively referred to as “dividends”) payable either in shares or in cash, nonparticipants in the Plan will receive cash, and participants in the Plan will receive the equivalent in common shares. The shares are acquired by the Plan Agent for the participant’s account, depending upon the circumstances described below, either (i) through receipt of additional unissued but authorized common shares from the Fund (“newly issued common shares”) or (ii) by purchase of outstanding common shares on the open-market (open-market purchases) on the NYSE Amex or elsewhere. If, on the payment date for any dividend or distribution, the net asset value per share of the common shares is equal to or less than the market price per common share plus estimated brokerage commissions (“market premium”), the Plan Agent will invest the amount of such dividend or distribution in newly issued shares on behalf of the participant. The number of newly issued common shares to be credited to the participant’s account will be determined by dividing the dollar amount of the dividend by the net asset value per share on the date the shares are issued, provided that the maximum discount from the then current market price per share on the date of issuance may not exceed 5%. If on the dividend payment date the net asset value per share is greater than the market value or market premium (“market discount”), the Plan Agent will invest the dividend amount in shares acquired on behalf of the participant in open-market purchases. There will be no brokerage charges with respect to shares issued directly by the Fund as a result of dividends or capital gains distributions payable either in shares or in cash. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent’s open-market purchases in connection with the reinvestment of dividends. The automatic reinvestment of dividends and distributions will not relieve participants of any federal, state or local income tax that may be payable (or required to be withheld) on such dividends. All correspondence concerning the Plan should be directed to the Plan Agent at P.O. Box 43010, Providence, Rhode Island 02940-3010 or by calling 1-800-730-6001.
