Chairman's
Letter to Shareholders

Dear Shareholders,

Despite the global economy's ability to muddle through the many economic headwinds of 2012, investors continue to have good reasons to remain cautious. The European Central Bank's decisions to extend intermediate term financing to major European banks and to support sovereign debt markets have begun to show signs of a stabilized euro area financial market. The larger member states of the European Union (EU) are working diligently to strengthen the framework for a tighter financial and banking union and meaningful progress has been made by agreeing to centralize large bank regulation under the European Central Bank. However, economic conditions in the southern tier members are not improving and the pressures on their political leadership remain intense. The jury is out on whether the respective populations will support the continuing austerity measures that are needed to meet the EU fiscal targets.

In the U.S., the Fed remains committed to low interest rates into 2015 through its third program of Quantitative Easing (QE3). Inflation remains low but a growing number of economists are expressing concern about the economic distortions resulting from negative real interest rates. The highly partisan atmosphere in Congress led to a disappointingly modest solution for dealing with the end-of-year tax and spending issues. Early indications for the new Congressional term have not given much encouragement that the atmosphere for dealing with the sequestration legislation and the debt ceiling issues, let alone a more encompassing "grand bargain," will be any better than the last Congress. Over the longer term, there are some encouraging trends for the U.S. economy: house prices are beginning to recover, banks and corporations continue to strengthen their financial positions and incentives for capital investment in the U.S. by domestic and foreign corporations are increasing due to more competitive energy and labor costs.

During 2012 U.S. investors have benefited from strong returns in the domestic equity markets and solid returns in most fixed income markets. However, many of the macroeconomic risks of 2012 remain unresolved, including negotiating through the many U.S. fiscal issues, managing the risks of another year of abnormally low U.S. interest rates, sustaining the progress being made in the euro area and reducing the potential economic impact of geopolitical issues, particularly in the Middle East. In the face of these uncertainties, the experienced investment professionals at Nuveen Investments seek out investments that are enjoying positive economic conditions. At the same time they are always on the alert for risks in markets subject to excessive optimism or for opportunities in markets experiencing undue pessimism. Monitoring this process is a critical function for the Fund Board as it oversees your Nuveen Fund on your behalf.

As always, I encourage you to communicate with your financial consultant if you have any questions about your investment in a Nuveen Fund. On behalf of the other members of your Fund Board, we look forward to continuing to earn your trust in the months and years ahead.

Sincerely,

Robert P. Bremner
Chairman of the Board
February 22, 2013

Nuveen Real Estate Income Fund (JRS)

The Fund is managed by a team of real estate investment professionals at Security Capital Research & Management Incorporated, a wholly-owned subsidiary of JPMorgan Chase & Co. Anthony R. Manno Jr., Kenneth D. Statz and Kevin W. Bedell lead the team and have managed JRS since its inception in 2001. Here they discuss general market conditions, their management strategy and performance of the Fund over the twelve-month period ended December 31, 2012.

What were the general market conditions and trends over the course of this reporting period?

During this period, the U.S. economy's progress toward recovery from recession continued at a moderate pace. The Federal Reserve (Fed) maintained its efforts to improve the overall economic environment by holding the benchmark fed funds rate at the record low level of zero to 0.25% that it established in December 2008. The central bank decided during its December 2012 meeting to keep the fed funds rate at "exceptionally low levels" until either the unemployment rate reaches 6.5% or expected inflation goes above 2.5%. The Fed also affirmed its decision, announced in September 2012, to purchase $40 billion of mortgage-backed securities each month in an effort to stimulate the housing market. In addition to this new, open-ended stimulus program, the Fed plans to continue its program to extend the average maturity of its holdings of U.S. Treasury securities through the end of December 2012. The goals of these actions, which together will increase the Fed's holdings of longer-term securities by approximately $85 billion a month through the end of the year, are to put downward pressure on longer-term interest rates, make broader financial conditions more accommodative and support a stronger economic recovery as well as continued progress toward the Fed's mandates of maximum employment and price stability.

In the fourth quarter 2012, the U.S. economy, as measured by the U.S. gross domestic product (GDP), decreased at an estimated annualized rate of 0.1%, down from a 3.1% increase in the third quarter. This slight decline was due to lower inventory investment, federal spending and net exports. The Consumer Price Index (CPI) rose 1.7% year-over-year as of December 2012, after a 3.0% increase in 2011. The core CPI (which excludes food and energy) increased 1.9% during the period, staying just within the Fed's unofficial objective of 2.0% or lower for this inflation measure. As of January 2013, the national unemployment rate was 7.9%, slightly higher than the 7.8% unemployment rate for December 2012 but below the 8.3% level recorded in January 2012. The housing market continued to show signs of improvement, with the average home price in the S&P/Case-Shiller Index of 20

major metropolitan areas rising 5.5% for the twelve months ended November 2012 (most recent data available at the time this report was prepared). This was the largest year-over-year price gain since August 2006. The outlook for the U.S. economy remained clouded by uncertainty about global financial markets and the continued negotiations by Congress regarding potential spending cuts and tax policy reform.

Along with broader U.S. equity markets, Real Estate Investment Trust (REIT) stocks endured a choppy end-of-year, but overall generated highly attractive returns for 2012 amidst emerging hopeful signs for a U.S. housing recovery, easing concerns regarding European financial markets and enthusiasm for continuing stimulus by the Fed. Returns for REIT senior securities were highly attractive in 2012 as well, aided among other things, by a continued narrowing of spreads as investors sought yield against historically low long-term interest rates.

What key strategies were used to manage the Fund during this reporting period?

The Fund is designed to invest at least 90% of its assets in income producing common stocks, preferred stocks, convertible preferred stocks and debt securities issued by real estate companies, with at least 80% of its total assets invested in income producing equity securities issued by REITs.

In managing the JRS portfolio, we sought to maintain significant property type and geographic diversification while taking into account company credit quality, sector and security-type allocations. Investment decisions are based on a multi-layered analysis of the company, the real estate it owns, its management and the relative price of the security, with a focus on securities that we believe will be best positioned to generate sustainable income and potential price appreciation over the long-run. In addition to fundamental security research, the proportion of the Fund invested in common equity versus preferred and fixed income investments is a key tactic we use to manage risk at a portfolio level. In general, in times of strong economic growth we position the portfolio towards more ownership of equity. In highly uncertain times, we tend to favor more allocation toward bonds and preferred securities. The allocation for the portfolio between equity, preferred and debt investments as of December 31, 2012 was 60% in equity, 35% in preferred, 1% in bonds and 4% in cash. This allocation is in-line with the long term "normal" allocation for managing this portfolio and reflects our strategy of balancing growth and risk in an economy experiencing a slow but uneven recovery.

How did the Fund perform during this twelve-month period ended December 31, 2012?

The performance of the Fund, as well as for comparative benchmark and indexes, is presented in the accompanying table.

Past performance is not predictive of future results. Current performance may be higher or lower than the data shown. Returns do not reflect the deduction of taxes that shareholders may have to pay on Fund distributions or upon the sale of Fund shares.

Average Annual Total Returns on Common Share Net Asset Value

For periods ended 12/31/12

For the twelve-month period ended December 31, 2012, the Fund outperformed its comparative indexes and benchmark.

For common equity investors in 2012, there were distinctive performance differences by property type. The underlying themes and influences reflecting company-specific factors, earlier performance differentials as well as shifting investor expectations colored by macro-economic trends. Almost irrespective of property type, among the year's top performers for 2012 were companies with rehabilitating balance sheets and more compatible asset portfolios. On the margin, these companies were aided significantly during the year by the continued saturation of capital markets with easy money working to narrow credit spreads and easy access to attractively priced debt and equity capital. This was in stark contrast with 2011, which saw outperformance by companies with the highest quality real estate portfolios often matched with the best balance sheets, the so-called Treasury trade in real estate. Also seemingly evident in the relative performance of property types in 2012 was investors' embracement of the beginning of a housing recovery which would confirm the strong outperformance of consumer driven retail and timber REIT stocks, and the relative underperformance of the multi-family stocks.

The Fund's performance benefited from its selection and allocation to perpetual preferred and debt securities during a volatile REIT common equity market. The Fund's selection of diversified equity investments constrained benchmark relative performance during the reporting period.

Fund Leverage
and Other Information

IMPACT OF THE FUND'S LEVERAGE STRATEGY ON PERFORMANCE

One important factor impacting the returns of this Fund relative to the comparative benchmark and indexes was the Fund's use of leverage through the use of bank borrowings. The Fund uses leverage because its managers believe that, over time, leveraging provides opportunities for additional income and total return for common shareholders. However, use of leverage also can expose common shareholders to additional volatility. For example, as the prices of securities held by the Fund decline, the negative impact of these valuation changes on common share net asset value and common shareholder total return is magnified by the use of leverage. Conversely, leverage may enhance common share returns during periods when the prices of securities held by a Fund generally are rising. Leverage had a positive impact on the performance of the Fund over this reporting period. During the period, the Fund entered into forward starting interest rate swap contracts, which have yet to become effective, in order to hedge future leverage costs. The combination of those forward starting swaps along with the existing interest rate swap contracts that were previously entered into in order to hedge a portion of the Fund's leverage costs partially detracted from the overall positive contribution of leverage. Short-term floating interest rates remained below the existing fixed swap rates for the period which increased realized leverage costs and exceeded the combined positive mark-to-market impact of unrealized gains.

RISK CONSIDERATIONS

Fund shares are not guaranteed or endorsed by any bank or other insured depository institution, and are not federally insured by the Federal Deposit Insurance Corporation. Shares of closed-end funds are subject to investment risks, including the possible loss of principal invested. Past performance is no guarantee of future results. Fund common shares are subject to a variety of risks, including:

Investment, Market and Price Risk. An investment in common shares is subject to investment risk, including the possible loss of the entire principal amount that you invest. Your investment in common shares represents an indirect investment in the corporate securities owned by the Fund, which generally trade in the over-the-counter markets. Shares of closed-end investment companies like the Fund frequently trade at a discount to their net asset value (NAV). Your common shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions.

Leverage Risk. The Fund's use of leverage creates the possibility of higher volatility for the Fund's per share NAV, market price and distributions. Leverage risk can be introduced through regulatory leverage (issuing preferred shares or debt borrowings at the

Fund level) or through certain derivative investments held in the Fund's portfolio. Leverage typically magnifies the total return of the Fund's portfolio, whether that return is positive or negative. The use of leverage creates an opportunity for increased common share net income, but there is no assurance that the Fund's leveraging strategy will be successful.

Tax Risk. The tax treatment of Fund distributions may be affected by new IRS interpretations of the Internal Revenue Code and future changes in tax laws and regulations. This is particularly true for funds employing a managed distribution program.

Real Estate Risks. The Fund's performance is linked to the performance of the commercial real estate markets, which may fall due to increasing vacancies, declining rents or the failure of borrowers to pay their loans.

Common Stock Risk. Common stock returns often have experienced significant volatility.

Issuer Credit Risk. This is the risk that a security in the Fund's portfolio will fail to make dividend or interest payments when due.

Dividend Income Risk. There is no guarantee that the issuers of common stocks in which the Fund invests will declare dividends in the future or that, if declared, they will remain at current levels or increase over time.

Preferred Stock Risk. Preferred stocks are subordinated to bonds and other debt instruments in a company's capital structure, and therefore are subject to greater credit risk.

Derivatives Strategy Risk. Derivative securities, such as calls, puts, warrants, swaps and forwards, carry risks different from, and possibly greater than, the risks associated with the underlying investments.

Interest Rate Risk. Fixed-income securities such as bonds, preferred, convertible and other debt securities will decline in value if market interest rates rise.

Reinvestment Risk: If market interest rates decline, income earned from the Fund's portfolio may be reinvested at rates below that of the original bond that generated the income.

Common Share Distribution
and Price Information

Distribution Information

The following information regarding the Fund's distributions is current as of December 31, 2012, and likely will vary over time based on the Fund's investment activities and portfolio investment value changes.

During the current reporting period, the Fund's quarterly distribution to common shareholders remained stable. Some of the important factors affecting the amount and composition of these distributions are summarized below.

The Fund employs financial leverage through the use of bank borrowings. Financial leverage provides the potential for higher earnings (net investment income), total returns and distributions over time, but—as noted earlier—also increases the variability of common shareholders' net asset value per share in response to changing market conditions.

The Fund has a managed distribution program. The goal of this program is to provide common shareholders with relatively consistent and predictable cash flow by systematically converting the Fund's expected long-term return potential into regular distributions. As a result, regular common share distributions throughout the year are likely to include a portion of expected long-term gains (both realized and unrealized), along with net investment income.

Important points to understand about the managed distribution program are:

•  The Fund seeks to establish a relatively stable common share distribution rate that roughly corresponds to the projected total return from its investment strategy over an extended period of time. However, you should not draw any conclusions about the Fund's past or future investment performance from its current distribution rate.

•  Actual common share returns will differ from projected long-term returns (and therefore the Fund's distribution rate), at least over shorter time periods. Over a specific timeframe, the difference between actual returns and total distributions will be reflected in an increasing (returns exceed distributions) or a decreasing (distributions exceed returns) Fund net asset value.

•  Each distribution is expected to be paid from some or all of the following sources:

•  net investment income (regular interest and dividends),

•  realized capital gains and

•  unrealized gains, or, in certain cases, a return of principal (non-taxable distributions).

•  A non-taxable distribution is a payment of a portion of the Fund's capital. When the Fund's returns exceed distributions, it may represent portfolio gains generated, but

**  The Fund elected to retain a portion of its realized long-term capital gains for the tax years ended December 31, 2007 and December 31, 2006, and pay required federal corporate income taxes on these amounts. As reported on Form 2439, Common shareholders on record date must include their pro-rata share of these gains on their applicable federal tax returns, and are entitled to take offsetting tax credits, for their pro-rata share of the taxes paid by the Fund. The total returns "Including retained gain tax credit/ refund" include the economic benefit to Common shareholders on record date of these tax credits/refunds. The Fund had no retained capital gains for the tax years ended December 31, 2012 through December 31, 2008 or for the tax years ended prior to December 31, 2006.

not realized as a taxable capital gain. In periods when the Fund's returns fall short of distributions, the shortfall will represent a portion of your original principal, unless the shortfall is offset during other time periods over the life of your investment (previous or subsequent) when the Fund's total return exceeds distributions.

•  Because distribution source estimates are updated during the year based on the Fund's performance and forecast for its current fiscal year (which is the calendar year for the Fund), estimates on the nature of your distributions provided at the time the distributions are paid may differ from both the tax information reported to you in your Fund's IRS Form 1099 statement provided at year end, as well as the ultimate economic sources of distributions over the life of your investment.

The following table provides information regarding the Fund's common share distributions and total return performance for the year ended December 31, 2012. This information is intended to help you better understand whether the Fund's returns for the specified time period were sufficient to meet the Fund's distributions.

Common Share Repurchases and Price Information

During November 2012, the Nuveen Funds Board of Directors/Trustees reauthorized the Fund's open-market share repurchase program, allowing the Fund to repurchase an aggregate of up to approximately 10% of its outstanding common shares.

As of December 31, 2012, and since the inception of the Fund's repurchase program, the Fund has not repurchased any of its outstanding common shares.

As of December 31, 2012, the Fund was trading at a -0.10% discount to its common share NAV, compared with an average premium of +6.41% for the entire twelve-month period.

HIGHLIGHTS

Selected data for a Common share outstanding throughout each period:

(a)  Per share Net Investment Income (Loss) is calculated using the average daily shares method.

(b)  The amounts shown are based on Common share equivalents.

(c)  Total Return Based on Market Value is the combination of changes in the market price per share and the effect of reinvested dividend income and reinvested capital gains distributions, if any, at the average price paid per share at the time of reinvestment. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last dividend declared in the period may take place over several days, and in some instances may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation. Total returns are not annualized.

  Total Return Based on Common Share Net Asset Value is the combination of changes in Common share net asset value, reinvested dividend income at net asset value and reinvested capital gains distributions at net asset value, if any. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending net asset value. The actual reinvest price for the last dividend declared in the period may often be based on the Fund's market price (and not its net asset value), and therefore may be different from the price used in the calculation. Total returns are not annualized.

FINANCIAL STATEMENTS

1. General Information and Significant Accounting Policies

General Information

Nuveen Real Estate Income Fund (the "Fund") is a diversified, closed-end registered investment company registered under the Investment Company Act of 1940, as amended. The Fund's Common shares are listed on the NYSE MKT (formerly known as NYSE Amex) and trade under the ticker symbol "JRS." The Fund was organized as a Massachusetts business trust on August 27, 2001.

On December 31, 2012, the Fund's investment adviser converted from a Delaware corporation to a Delaware limited liability company. As a result, Nuveen Fund Advisors, Inc., a wholly-owned subsidiary of Nuveen Investments, Inc. ("Nuveen"), changed its name to Nuveen Fund Advisors, LLC (the "Adviser"). There were no changes to the identities or roles of any personnel as a result of the change.

The Fund seeks to provide high current income and capital appreciation by investing at least 90% of its total assets in income producing common stocks, preferred stocks, convertible preferred stocks and debt securities issued by real estate companies; at least 80% of its total assets in income producing equity securities issued by Real Estate Investment Trusts ("REITs"); and will not invest more than 25% of its total assets in non-investment grade preferred stocks, convertible preferred stocks and debt securities.

Significant Accounting Policies

The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements in accordance with U.S. generally accepted accounting principles ("U.S. GAAP").

Investment Valuation

Common stocks and other equity-type securities are valued at the last sales price on the securities exchange on which such securities are primarily traded and are generally classified as Level 1 for fair value measurement purposes. Securities primarily traded on the NASDAQ National Market ("NASDAQ") are valued, except as indicated below, at the NASDAQ Official Closing Price and are generally classified as Level 1. However, securities traded on a securities exchange or NASDAQ for which there were no transactions on a given day or securities not listed on a securities exchange or NASDAQ are valued at the quoted bid price and are generally classified as Level 2.

Prices of fixed-income securities and interest rate swap contracts are provided by a pricing service approved by the Fund's Board of Trustees. These securities are generally classified as Level 2. The pricing service establishes a security's fair value using methods that may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor's credit characteristics considered relevant. In pricing certain securities, particularly less liquid and lower quality securities, the pricing service may consider information about a security, its issuer, or market activity provided by the Adviser. These securities are generally classified as Level 2 or Level 3 depending on the priority of the significant inputs.

Repurchase agreements are valued at contract amount plus accrued interest, which approximates market value. These securities are generally classified as Level 2.

Certain securities may not be able to be priced by the pre-established pricing methods as described above. Such securities may be valued by the Fund's Board of Trustees or its designee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; debt securities that have gone into default and for which there is no current market quotation; a security whose market price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund's net asset value (as may be the case in non-U.S. markets on which the security is primarily traded) or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, is not deemed to reflect the security's fair value. As a general principle, the fair value of a security would appear to be the amount that the owner might reasonably expect to receive for it in a current sale. A variety of factors

may be considered in determining the fair value of such securities, which may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor's credit characteristics considered relevant. These securities are generally classified as Level 2 or Level 3 depending on the priority of the significant inputs. Regardless of the method employed to value a particular security, all valuations are subject to review by the Fund's Board of Trustees or its designee.

Refer to Footnote 2—Fair Value Measurements for further details on the leveling of securities held by the Fund as of the end of the reporting period.

Investment Transactions

Investment transactions are recorded on a trade date basis. Realized gains and losses from transactions are determined on the specific identification method, which is the same basis used for federal income tax purposes. Investments purchased on a when-issued/delayed delivery basis may have extended settlement periods. Any investments so purchased are subject to market fluctuation during this period. The Fund has instructed the custodian to earmark securities in the Fund's portfolio with a current value at least equal to the amount of the when-issued/delayed delivery purchase commitments. As of December 31, 2012, the Fund had no such outstanding purchase commitments.

Investment Income

Dividend income is recorded on the ex-dividend date or, for foreign securities, when information is available. Interest income, which reflects the amortization of premiums and includes accretion of discounts for financial reporting purposes, is recorded on an accrual basis. Interest income also reflects paydown gains and losses, if any.

Income Taxes

The Fund intends to distribute substantially all of its investment company taxable income to shareholders and to otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. In any year when the Fund realizes net capital gains, the Fund may choose to distribute all or a portion of its net capital gains to shareholders, or alternatively, to retain all or a portion of its net capital gains and pay federal corporate income taxes on such retained gains.

For all open tax years and all major taxing jurisdictions, management of the Fund has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. Open tax years are those that are open for examination by taxing authorities (i.e., generally the last four tax year ends and the interim tax period since then). Furthermore, management of the Fund is also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

Dividends and Distributions to Common Shareholders

Distributions to Common shareholders are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

The Fund makes quarterly cash distributions to Common shareholders of a stated dollar amount per share. Subject to approval and oversight by the Fund's Board of Trustees, the Fund seeks to maintain a stable distribution level designed to deliver the long-term return potential of the Fund's investment strategy through regular quarterly distributions (a "Managed Distribution Program"). Total distributions during a calendar year generally will be made from the Fund's net investment income, net realized capital gains and net unrealized capital gains in the Fund's portfolio, if any. The portion of distributions paid attributed to net unrealized gains, if any, is distributed from the Fund's assets and is treated by shareholders as a non-taxable distribution ("Return of Capital") for tax purposes. In the event that total distributions during a calendar year exceed the Fund's total return on net asset value, the difference will reduce net asset value per share. If the Fund's total return on net asset value exceeds total distributions during a calendar year, the excess will be reflected as an increase in net asset value per share. The final determination of the source and character of all distributions for the fiscal year are made after the end of the fiscal year and are reflected in the financial statements contained in the annual report as of December 31 each year.

REIT distributions received by the Fund are generally comprised of ordinary income, long-term capital gains, and a return of REIT capital. The actual character of amounts received during the period are not known until after the fiscal year-end. For the fiscal year ended December 31, 2012, the character of distributions to the Fund from the REITs was 78.85% ordinary income, 13.13% long-term capital gains and 8.02% return of REIT capital. For the fiscal year ended December 31, 2011, the character of distributions to the Fund from the REITs was 71.66% ordinary income, 16.37% long-term capital gains and a 11.97% return of REIT capital.

For the fiscal years ended December 31, 2012 and December 31, 2011, the Fund applied the actual character of distributions reported by the REITs in which the Fund invests to its receipts from the REITs. If a REIT held in the portfolio of investments did not report the actual character of its distributions during the period, the Fund treated the distributions as ordinary income.

The actual character of distributions made by the Fund during the fiscal years ended December 31, 2012 and December 31, 2011, is reflected in the accompanying financial statements.

FINANCIAL STATEMENTS (continued)

Taxable Auctioned Preferred Shares

The Fund is authorized to issue auction rate preferred ("Taxable Auctioned Preferred") shares. As of December 31, 2009, the Fund redeemed all $222,000,000 of its outstanding Taxable Auctioned Preferred shares, at liquidation value.

Foreign Currency Transactions

The Fund is authorized to engage in foreign currency transactions, including forward foreign currency exchange contracts, futures, options and swap contracts. To the extent that the Fund invests in securities and/or contracts that are denominated in a currency other than U.S. dollars, the Fund will be subject to currency risk, which is the risk that an increase in the U.S. dollar relative to the foreign currency will reduce returns or portfolio value. Generally, when the U.S. dollar rises in value against a foreign currency, the Fund's investments denominated in that currency will lose value because its currency is worth fewer U.S. dollars; the opposite effect occurs if the U.S. dollar falls in relative value. Investments and other assets and liabilities denominated in foreign currencies are converted into U.S. dollars on a spot (i.e. cash) basis at the spot rate prevailing in the foreign currency exchange market at the time of valuation. Purchases and sales of investments and income denominated in foreign currencies are translated into U.S. dollars on the respective dates of such transactions.

The books and records of the Fund are maintained in U.S. dollars. Foreign currencies, assets and liabilities are translated into U.S. dollars at 4:00 p.m. Eastern Time. Investment transactions, income and expenses are translated on the respective dates of such transactions. Net realized foreign currency gains and losses resulting from changes in exchange rates include foreign currency gains and losses between trade date and settlement date of the transactions, foreign currency transactions, and the difference between the amounts of interest and dividends recorded on the books of the Fund and the amounts actually received.

The realized gains and losses resulting from changes in foreign currency exchange rates and changes in foreign exchange rates associated with other assets and liabilities on investments are recognized as a component of "Net realized gain (loss) from investments and foreign currency," on the Statement of Operations, when applicable.

The unrealized gains and losses resulting from changes in foreign currency exchange rates and changes in foreign exchange rates associated with other assets and liabilities on investments are recognized as a component of "Change in net unrealized appreciation (depreciation) of investments and foreign currency," on the Statement of Operations, when applicable. The unrealized gains and losses resulting from changes in foreign exchange rates associated with forward foreign currency exchange contracts, futures, options purchased, options written and swaps are recognized as a component of "Change in net unrealized appreciation (depreciation) of forward foreign currency exchange contracts, futures, options purchased, options written and swap contracts," respectively, on the Statement of Operations, when applicable.

Interest Rate Swap Contracts

The Fund is subject to interest rate risk in the normal course of pursuing its investment objectives and is authorized to invest in interest rate swap transactions in an attempt to manage such risk. The Fund's use of interest rate swap contracts is intended to mitigate the negative impact that an increase in short-term interest rates could have on Common share net earnings as a result of leverage. Forward interest rate swap transactions involve the Fund's agreement with a counterparty to pay, in the future, a fixed or variable rate payment in exchange for the counterparty paying the Fund a variable or fixed rate payment, the accruals for which would begin at a specified date in the future (the "effective date"). Interest rate swap contracts involve the Fund's agreement with the counterparty to pay or receive a fixed rate payment in exchange for the counterparty receiving or paying a variable rate payment that is intended to approximate the Fund's variable rate payment obligation on Taxable Auctioned Preferred shares or any variable rate borrowing. The payment obligation is based on the notional amount of the interest rate swap contract. Interest rate swap contracts do not involve the delivery of securities or other underlying assets or principal. Accordingly, the risk of loss with respect to the swap counterparty on such transactions is limited to the net amount of interest payments that the Fund is to receive. Interest rate swap positions are valued daily. The Fund accrues the fixed rate payment expected to be paid or received and the variable rate payment expected to be received or paid on interest rate swap contracts on a daily basis, and recognizes the daily change in the fair value of the Fund's contractual rights and obligations under the contracts. The net amount recorded for these transactions for each counterparty is recognized on the Statement of Assets and Liabilities as a component of "Unrealized appreciation or depreciation on interest rate swaps (, net)" with the change during the fiscal period recognized on the Statement of Operations as a component of "Change in net unrealized appreciation (depreciation) of interest rate swaps." Income received or paid by the Fund is recognized as a

component of "Net realized gain (loss) from interest rate swaps" on the Statement of Operations, in addition to the net realized gains or losses recognized upon the termination of an interest rate swap contract and are equal to the difference between the Fund's basis in the interest rate swap and the proceeds from (or cost of) the closing transaction. Payments received or made at the beginning of the measurement period are recognized as a component of "Interest rate swap premiums paid and/or received" on the Statement of Assets and Liabilities, when applicable. For tax purposes, periodic payments are treated as ordinary income or expense.

During the fiscal year ended December 31, 2012, the Fund continued to use interest rate swap contracts to partially fix the interest cost of leverage, which the Fund uses through the use of bank borrowings.

The average notional amount of interest rate swaps contracts outstanding during the fiscal year ended December 31, 2012, was as follows:

*  The average notional amount is calculated based on the outstanding notional at the beginning of the fiscal year and at the end of each fiscal quarter within the current fiscal year.

Refer to Footnote 3—Derivative Instruments and Hedging Activities for further details on interest rate swap contract activity.

Market and Counterparty Credit Risk

In the normal course of business the Fund may invest in financial instruments and enter into financial transactions where risk of potential loss exists due to changes in the market (market risk) or failure of the other party to the transaction to perform (counterparty credit risk). The potential loss could exceed the value of the financial assets recorded on the financial statements. Financial assets, which potentially expose the Fund to counterparty credit risk, consist principally of cash due from counterparties on forward, option and swap transactions, when applicable. The extent of the Fund's exposure to counterparty credit risk in respect to these financial assets approximates its carrying value as recorded on the Statement of Assets and Liabilities. Futures contracts, when applicable, expose the Fund to minimal counterparty credit risk as they are exchange traded and the exchange's clearing-house, which is counterparty to all exchange traded futures, guarantees the futures contracts against default.

The Fund helps manage counterparty credit risk by entering into agreements only with counterparties the Adviser believes have the financial resources to honor their obligations and by having the Adviser monitor the financial stability of the counterparties. Additionally, counterparties may be required to pledge collateral daily (based on the daily valuation of the financial asset) on behalf of the Fund with a value approximately equal to the amount of any unrealized gain above a pre-determined threshold. Reciprocally, when the Fund has an unrealized loss, the Fund has instructed the custodian to pledge assets of the Fund as collateral with a value approximately equal to the amount of the unrealized loss above a pre-determined threshold. Collateral pledges are monitored and subsequently adjusted if and when the valuations fluctuate, either up or down, by at least the pre-determined threshold amount.

Repurchase Agreements

In connection with transactions in repurchase agreements, it is the Fund's policy that its custodian take possession of the underlying collateral securities, the fair value of which exceeds the principal amount of the repurchase transaction, including accrued interest, at all times. If the counterparty defaults, and the fair value of the collateral declines, realization of the collateral may be delayed or limited.

Indemnifications

Under the Fund's organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Fund. In addition, in the normal course of business, the Fund enters into contracts that provide general indemnifications to other parties. The Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets applicable to Common shares from operations during the reporting period. Actual results may differ from those estimates.

2. Fair Value Measurements

Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The following is a summary of the three-tiered hierarchy of valuation input levels.

Notes to

FINANCIAL STATEMENTS (continued)

Level 1 —  Inputs are unadjusted and prices are determined using quoted prices in active markets for identical securities.

Level 2 —  Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).

Level 3 —  Prices are determined using significant unobservable inputs (including management's assumptions in determining the fair value of investments).

The inputs or methodologies used for valuing securities are not an indication of the risks associated with investing in those securities. The following is a summary of the Fund's fair value measurements as of the end of the reporting period:

*  Refer to the Fund's Portfolio of Investments for industry classifications and breakdown of Real Estate Investment Trust Preferred Stocks classified as Level 2.

**  Represents net unrealized appreciation (depreciation) as reported in the Fund's Portfolio of Investments.

The Nuveen funds' Board of Directors/Trustees is responsible for the valuation process and has delegated the oversight of the daily valuation process to the Adviser's Valuation Committee. The Valuation Committee, pursuant to the valuation policies and procedures adopted by the Board of Directors/Trustees, is responsible for making fair value determinations, evaluating the effectiveness of the funds' pricing policies, and reporting to the Board of Directors/Trustees. The Valuation Committee is aided in its efforts by the Adviser's dedicated Securities Valuation Team, which is responsible for administering the daily valuation process and applying fair value methodologies as approved by the Valuation Committee. When determining the reliability of independent pricing services for investments owned by the funds, the Valuation Committee, among other things, conducts due diligence reviews of the pricing services and monitors the quality of security prices received through various testing reports conducted by the Securities Valuation Team.

The Valuation Committee will consider pricing methodologies it deems relevant and appropriate when making fair value determinations. Examples of possible methodologies include, but are not limited to, multiple of earnings; discount from market of a similar freely traded security; discounted cash-flow analysis; book value or a multiple thereof; risk premium/yield analysis; yield to maturity; and/or fundamental investment analysis. The Valuation Committee will also consider factors it deems relevant and appropriate in light of the facts and circumstances. Examples of possible factors include, but are not limited to, the type of security; the issuer's financial statements; the purchase price of the security; the discount from market value of unrestricted securities of the same class at the time of purchase; analysts' research and observations from financial institutions; information regarding any transactions or offers with respect to the security; the existence of merger proposals or tender offers affecting the security; the price and extent of public trading in similar securities of the issuer or comparable companies; and the existence of a shelf registration for restricted securities.

For each portfolio security that has been fair valued pursuant to the policies adopted by the Board of Directors/Trustees, the fair value price is compared against the last available and next available market quotations. The Valuation Committee reviews the results of such testing and fair valuation occurrences are reported to the Board of Directors/Trustees.

3. Derivative Instruments and Hedging Activities

The Fund records derivative instruments at fair value, with changes in fair value recognized on the Statement of Operations, when applicable. Even though the Fund's investments in derivatives may represent economic hedges, they are not considered to be hedge

transactions for financial reporting purposes. For additional information on the derivative instruments in which the Fund was invested during and at the end of the reporting period, refer to the Portfolio of Investments, Financial Statements and Footnote 1—General Information and Significant Accounting Policies.

The following table presents the fair value of all derivative instruments held by the Fund as of December 31, 2012, the location of these instruments on the Statement of Assets and Liablilities, and the primary underlying risk exposure.

The following tables present the amount of net realized gain (loss) and change in net unrealized appreciation (depreciation) recognized for the fiscal year ended December 31, 2012, on derivative instruments, as well as the primary risk exposure associated with each.

Common Shares

Since the inception of the Fund's repurchase program, the Fund has not repurchased any of its outstanding Common shares.

Transactions in Common shares were as follows:

5. Investment Transactions

Purchases and sales (including maturities but excluding short-term investments and derivative transactions) during the fiscal year ended December 31, 2012, aggregated $220,900,201 and $233,282,731, respectively.

6. Income Tax Information

The following information is presented on an income tax basis. Differences between amounts for financial statement and federal income tax purposes are primarily due to timing differences in recognizing certain gains and losses on investment transactions. To the extent that differences arise that are permanent in nature, such amounts are reclassified within the capital accounts as detailed below. Temporary differences do not require reclassification. Temporary and permanent differences do not impact the net asset value of the Fund.

As of December 31, 2012, the cost and unrealized appreciation (depreciation) of investments (excluding investments in derivatives), as determined on a federal income tax basis, were as follows:

Permanent differences, primarily due to tax basis earnings and profits adjustments and treatment of notional principal contracts, resulted in reclassifications among the Fund's components of common share net assets at December 31, 2012, the Fund's tax year end, as follows:
