Chairman's Letter

to Shareholders

Dear Shareholders,

I am pleased to have this opportunity to introduce myself to you as the new independent chairman of the Nuveen Fund Board, effective July 1, 2013. I am honored to have been selected as chairman, with its primary responsibility to serve the interests of the Nuveen Fund shareholders. My predecessor, Robert Bremner, was the first independent director to serve as chairman of the Board and I, and my fellow Board members, plan to continue his legacy of strong independent oversight of your funds.

The global economy has hit major turning points over the last several months to a year. The developed world is gradually recovering from its financial crisis while the emerging markets appear to be struggling with the downshift of China's growth potential. Japan is entering a new era of growth after decades of economic stagnation and many of the Eurozone nations appear to be exiting their recession. Despite the positive events, there are still potential risks. Middle East tensions, rising oil prices, defaults in Europe and fallout from the financial stress in emerging markets could all reverse the recent progress in the global economy.

On the domestic front, recent events such as the Federal Reserve decision to slow down its bond buying program beginning in January of 2014 and the federal budget compromise that would guide government spending into 2015 are both positives for the economy moving forward. Corporate fundamentals are strong as earnings per share and corporate cash are at the highest level in two decades. Unemployment is trending down and the housing market has experienced a rebound, each assisting the positive economic scenario. However, there are some issues to be watched. Interest rates are expected to increase but significant uncertainty about the timing remains. Partisan politics in Washington D.C. with their troublesome outcomes add to the uncertainties that could cause problems for the economy going forward.

In the near term, governments are focused on economic recovery and the growth of their economies, which could lead to an environment of attractive investment opportunities. Over the long term, the uncertainties mentioned earlier could hinder the potential growth. Because of this, Nuveen's investment management teams work hard to balance return and risk with a range of investment strategies. I encourage you to read the following commentary on the management of your fund.

On behalf of the other members of the Nuveen Fund Board, we look forward to continuing to earn your trust in the months and years ahead.

William J. Schneider
Chairman of the Nuveen Fund Board

Portfolio Managers'

Comments

Nuveen Diversified Dividend and Income Fund (JDD)

JDD features portfolio management by teams at four separate sub-advisers. Each sub-adviser has a strategic asset allocation of 25% of the Fund's assets.

NWQ Investment Management Company, LLC (NWQ), an affiliate of Nuveen Investments, invests its portion of the Fund's assets primarily in dividend-paying common stocks. Jon D. Bosse, CFA, Chief Investment Officer and James T. Stephenson, CFA, lead the Fund's management team at the firm.

The real estate portion of the Fund's investment portfolio is managed by a team at Security Capital Research & Management Incorporated (Security Capital), a wholly-owned subsidiary of JPMorgan Chase & Company. Anthony R. Manno Jr., Kenneth D. Statz and Kevin W. Bedell lead the management team.

Symphony Asset Management LLC (Symphony), an affiliate of Nuveen Investments, invests its portion of the Fund's assets primarily in senior loans. The Symphony team is led by Gunther Stein, Chief Investment Officer.

Wellington Management Company, LLP (Wellington Management) invests its portion of the Fund's assets in emerging markets sovereign debt. James W. Valone, CFA, heads the management team.

Here representatives from NWQ, Security Capital, Symphony and Wellington Management discuss general market conditions and trends, their management strategies and the performance of the Fund for the twelve-month reporting period ended December 31, 2013.

What factors affected the U.S. economy and the equity market during the twelve-month reporting period ended December 31, 2013?

During the first part of this reporting period, widespread uncertainty about the next step for the Federal Reserve's (Fed) quantitative easing program and the potential impact on the economy and financial markets led to increased market volatility. After surprising the market in September 2013 with its decision to wait for additional evidence of an improving economy before making any adjustments to the program, the Fed announced on December 18, 2013 that it would begin tapering its monthly bond-buying program by $10 billion (to $75 billion) in January 2014. The outlook for the U.S. economy was clouded by uncertainty about global financial markets and the outcome of the "fiscal cliff." The tax consequences of the fiscal cliff situation were averted through a last-minute deal that raised payroll taxes, but left in place a number of tax breaks. However, lawmakers failed to reach a resolution on $1.2 trillion in spending cuts intended to address the federal budget deficit. This triggered a program of automatic spending cuts (or sequestration) that impacted federal programs beginning March 1, 2013. Although Congress later passed legislation that established federal funding levels for the remainder of fiscal 2013, the federal budget for fiscal 2014 continued to be debated.

Portfolio Managers' Comments (continued)

On October 1, 2013, the start date for fiscal 2014, the federal government shut down for 16 days until an interim appropriations bill was signed into law, funding the government at sequestration levels through January 15, 2014, and suspending the debt limit until February 7, 2014. At the end of the reporting period, Congress passed a federal budget deal that would guide government spending into 2015 and defuse the chances of another shutdown. In addition to the ongoing political debate over federal spending, Chairman Bernanke's June 2013 remarks about tapering the Fed's asset purchase program touched off widespread uncertainty about the next step for the Fed's quantitative easing program and about the potential impact on the economy and financial markets, leading to increased market volatility.

In the third quarter of 2013, the U.S. economy, as measured by the U.S. gross domestic product (GDP), grew at an annualized rate of 4.1%, up from 2.5% for the second quarter of 2013, continuing the pattern of positive economic growth for the tenth consecutive quarter. The Consumer Price Index (CPI) rose 1.5% year-over-year as of December 2013, while the core CPI (which excludes food and energy) increased 1.7% during the same period, staying within the Fed's unofficial objective of 2.0% or lower for this inflation measure. Improvements in the labor markets continued to be slow, and unemployment remained above the Fed's target of 6.5%. As of December 2013, the national unemployment rate was 6.7%, down from 7.0% in November 2013. The housing market continued to deliver good news, as the average home price in the S&P/Case-Shiller Index of 20 major metropolitan areas rose 13.7% for the twelve months ended November 2013 (most recent data available at the time this report was prepared), the largest twelve-month percentage gain for the index since February 2006.

For much of the reporting period, low interest rates and a fairly benign macro environment caused U.S. investors to move out the risk spectrum, resulting in robust flows into U.S. equity funds. Leading U.S. stock market indexes, including the S&P 500^® Index, the Dow Jones Industrial Average and the Russell 2000^® Index, each hit all-time highs during the reporting period. The S&P 500^® Index gained 32.39% and the Dow Jones Industrial Average gained 29.65% during the reporting period. Gold suffered its first annual decline since 2000. The Nikkei Index rose 57%, while most European developed markets generated double digit returns. Easing money policies by the world's central banks continued, joined by significant steps in Japan, while economic growth remained weak. Returns from most developing markets underperformed developed markets, with China and Brazil both posting negative returns for the reporting period.

Real Estate Investment Trust (REIT) common equities generated modestly positive returns for 2013. In contrast, concerns over rising interest rate trends were evident as REIT senior fixed income securities generated negative returns for 2013, particularly the perpetual preferred securities burdened by their extended duration profile.

Performance across the emerging markets fixed income sectors was negative during the reporting period. External sovereign debt as measured by the JPMorgan Emerging Markets Bond Index (EMBI) Global Diversified returned -5.25%, as both spread widening and rising of U.S. Treasury yields hurt performance. Corporate debt had slightly negative performance with the JPMorgan Chase Corporate Emerging Bond Index (CEMBI) Broad Diversified Index generating -0.60%, as spread tightening partially offset the negative impact of the rise in U.S. Treasury yields. Local currency markets struggled, with the JPMorgan Government Bond Index – Emerging Markets (GBI-EM) Global Diversified Index posting a return of -8.98% for the reporting period. Both the weakening of emerging markets currencies versus the U.S. dollar and the rise of interest rates in the face of declining global liquidity hurt local markets.

What were the key strategies used to manage the Fund during this twelve-month reporting period ended December 31, 2013?

The Fund's investment objectives are high current income and total return. In its efforts to achieve these objectives, the Fund invests primarily in 1) U.S. and foreign dividend paying common stocks, 2) dividend paying common stocks issued by real estate companies, 3) emerging markets sovereign debt, and 4) senior secured loans. The Fund expects to invest at least 40%, but no more than 70%, of its assets in equity security holdings and at least 30%, but no more than 60%, of its assets in debt security holdings. Under normal circumstances, the Fund's target weighting is approximately 50% equity and 50% debt.

For the dividend paying equity portion of the Fund's portfolio, managed by NWQ, we continued to employ an opportunistic, bottom-up strategy that focused on identifying undervalued companies possessing favorable risk/reward characteristics as well as emerging catalysts that can unlock value or improve profitability. These catalysts included management changes, restructuring efforts, recognition of hidden assets or a positive change in the underlying fundamentals. We also focused on trying to manage downside risk exposure, and focused on each company's balance sheet and cash flow statement, not just the income statement. We believe that cash flow analysis offers a more objective and truer picture of a company's financial position than an evaluation based on earnings alone.

In managing the real estate portion of the portfolio, Security Capital seeks 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. Across all real estate sectors, Security Capital favored companies with properties located in the strongest infill markets. These "high barrier to entry" markets are defined by constraints that limit new construction, a quality that over the long-term has the potential to provide superior value enhancement and a real inflation hedge.

In the senior loan and other debt portion of the Fund's portfolio, the Symphony team continued to manage and monitor senior loan market risks. Investors who took credit risk were rewarded during the reporting period and defaults averaged below 2% for the senior loan market. All industries had positive returns during the reporting period, with any weaknesses in very specific issuers. The Fund's capital remained invested in assets offering attractive current income and yield, whose issuers have relatively strong credit profiles among non-investment grade debt.

The emerging market debt portion of the Fund is managed by Wellington Management. During the reporting period, we remained overweight Latin America, but shifted our positioning by adding to our external sovereign debt exposure while trimming our quasi-sovereign and corporate exposures. We favored external sovereign debt as we believe that default risk remains relatively low and spreads are attractive. We favored countries such as Brazil and Colombia, but moved to an underweight in Venezuela where we had fundamental concerns. Although we remain broadly cautious on the Eastern Europe, Middle East and Africa (EEMEA) region, we do still favor Russia and some smaller markets in Eastern Europe that could experience spread compression as credit quality improves in Lithuania, Latvia and Romania. We avoided those Middle Eastern countries that were going through difficult political transitions. We had exposure to high quality countries with attractive valuations such as the United Arab Emirates. We remained underweight in Asia given tight valuations, though we have taken advantage of weakness in Indonesia to add some exposure. During the reporting period, our local interest rate exposure was light and largely concentrated in Latin America and South Africa. We also added local rates exposure to Russian bonds during the reporting period. We also trimmed our emerging markets currency exposure as macro risks heated up. We trimmed currencies across all regions, as we believe they were vulnerable to Fed tapering risks. We anticipate that emerging markets central banks will likely fight depreciation aggressively in the hopes that it improves their competitiveness and boosts export growth. Finally, we have scaled back corporate exposure, in the face of expected heavy supply and relative outperformance in those issuers that are well positioned to weather a period of market volatility.

How did the Fund perform during this twelve-month reporting period ended December 31, 2013?

The table in the Performance Overview and Holding Summaries section of this report provides total return performance for the Fund for the one-year, five-year and ten-year periods ended December 31, 2013. For the twelve-month reporting period ended December 31, 2013, the total return on common share net asset value (NAV) for the Fund outperformed its comparative benchmark, but underperformed the S&P 500^® Index.

Within the dividend paying equity portion of the Fund managed by NWQ, the portfolio's performance reflects strong gains in several holdings. Those sectors that contributed positively to performance included consumer discretionary and finance due to positive stock selection and a greater weighting compared to the benchmark. Holdings in the technology,

Portfolio Managers' Comments (continued)

producer durables and utility (telecom) sectors also generated strong gains; however, the portfolio's allocation to these sectors was less than the benchmark, which detracted from the relative return. These gains were partially offset by negative stock selection in the energy, health care and consumer staples sectors. Gold mining stocks AngloGold Ashanti and Barrick Gold performed poorly for the reporting period.

Several portfolio holdings generated double-digit returns for the reporting period on the strength of improving fundamentals, corporate activism and an acceleration in the return of capital to shareholders. Interpublic Group appreciated as the company's operational and financial turnaround continued to progress with an improved capital structure and higher free cash flow. Organic revenue growth is also set to exceed peers as headwinds from prior account losses begin to fade and new account wins further strengthen the company's growth outlook. Hartford Financial also positively contributed to performance. The company has done an excellent job selling its life businesses, mitigating risk in its run-off variable annuity division (Talcott) and returning capital to shareholders via share repurchase and dividends (dividends increased significantly during 2013). In addition, Unum Group contributed to the Fund's positive performance. The market has finally recognized the company has earned a 9-10% return-on-equity even in a tough environment, exhibiting great discipline in underwriting and returning significant capital via a robust dividend and share repurchase. Lastly, Vodafone appreciated as Verizon Communications agreed to acquire Vodafone's 45% stake in Verizon Wireless, while shares of Viacom benefitted from improved ratings at Nickelodeon and MTV, which is helping to drive advertising and revenue growth.

As previously mentioned, gold stocks AngloGold Ashanti and Barrick Gold were a significant drag on performance. Our positive perspective on these holdings entering 2013 was driven by the expectation that value would be liberated and protected through asset sales and spin-offs, a focus on cost and capital discipline and production growth from lower cost mines. We felt those characteristics would make these companies attractive in any industry, however, there was a 28% drop in the price of the underlying commodity. Many of the positive change catalysts remain, and although the commodity outlook remains uncertain, we would note that the current price of gold approximates the all-in marginal cost of production.

Lastly, Mosaic Company also declined due to lower potash and phosphate prices. Potash prices were pressured as Russian fertilizer producer, Uralkali, withdrew from its cartel marketing agreement with the Belarusian state potash producer, Belaruskali, BPC, which may result in additional potash volume in the market.

We opportunistically added several new holdings to the portfolio based on improving fundamentals, compelling valuation and an attractive dividend yield. Examples include new positions in Avery Dennison, CenturyLink, Norwegian Cruise Lines and Phillips 66. Following the divestiture of its office labels business, Avery Dennison appears to be more focused on simplifying its operations and optimizing its working capital requirements. We believe the stock is undervalued given the company's greater focus on free cash flow generation and shareholder value. Norwegian Cruise Lines generates above industry average yields and we believe the company is poised to significantly outgrow the industry with four new ships joining its fleet. Even with these advantages, the stock trades at a discount to the group, which we view as both unwarranted and unsustainable. We believe Phillips 66 has a favorable multi-year tailwind in its chemicals and midstream businesses. Long term, we believe both of these businesses will grow to over two-thirds of the total company, positioning Phillips 66 for continued free cash flow growth and a potential upward multiple re-rating. The company's refining business is also poised to benefit from widening West Texas Intermediate (WTI) to brent blend crude differentials that could drive additional earnings growth.

Several holdings were eliminated or trimmed during the year based on valuation, deteriorating fundamentals or to raise cash as we rotated into new investment opportunities. Among the holdings eliminated were News Corp, Symetra Financial, Tyson Foods and Teva Pharmaceutical. We rotated out of Newmont Mining and replaced the proceeds into AuRico Gold and purchased Suncor Energy after selling Canadian Natural Resources Limited and Talisman Energy Inc. Applied Materials, MetLife and Halliburton were sold based on valuation.

In the real estate portion of the Fund managed by Security Capital, the Fund's performance benefited from its regional mall, industrial, strip center and self-storage equity investments, however performance was constrained by equity investments in office, hotels, mixed industrial/office and health care investments.

The broad loan market returned 6.16% during the reporting period and exhibited minimal volatility with only one down month. The senior loan and other debt portion of the Fund managed by Symphony benefited from credit selection and strong market technicals, including robust retail demand and collateralized loan obligation issuance. Our positions in Federal-Mogul Corporation and U.S. Foods performed well during the reporting period. Detracting from performance was TXU Corporation, whose loans traded down as investors await regulatory changes to the local power market.

In the emerging markets debt portion of the portfolio managed by Wellington Management, security selection contributed to overall performance, outweighing the negative contribution from country rotation strategies. Among country rotation strategies, an underweight to Uruguay, Venezuela and Panama contributed to overall performance, while a lack of exposure to Lebanon, as well as an overweight to Brazil and Indonesia detracted. Within security selection, positioning in Indonesia, Turkey and Peru contributed to overall performance, while security selection in Mexico, Brazil and Lithuania detracted. We also used currency forward contracts, buying currencies we expected to appreciate and selling currencies we expected to depreciate. These contracts contributed to overall performance during the period.

We also wrote (sold) call options on individual stocks, while investing in those same stocks, to enhance returns while foregoing some upside potential. The effect on performance for the reporting period was negative.

Fund

Leverage

IMPACT OF THE FUND'S LEVERAGE STRATEGY ON PERFORMANCE

One important factor impacting the return of the Fund relative to its benchmarks was the Fund's use of leverage through the use of bank borrowings. The Fund uses leverage because our research has shown that, over time, leveraging provides opportunities for additional income and total return for shareholders. However, use of leverage also can expose 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 NAV 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 the Fund generally are rising. The Fund's use of leverage had a positive impact on performance during this reporting period.

The Fund also continued to use swap contracts to partially fix the interest cost of leverage, which as mentioned previously, the Fund uses through bank borrowings. The swap contracts impact on performance was slightly positive during this reporting period.

As of December 31, 2013, the Fund's percentages of leverage are as shown in the accompanying table.

*  Effective leverage is the Fund's effective economic leverage, and includes both regulatory leverage and the leverage effects of certain derivative and other investments in the Fund's portfolio that increase the Fund's investment exposure. Regulatory leverage consists of preferred shares issued or borrowings of the Fund. Both of these are part of the Fund's capital structure. Regulatory leverage is subject to asset coverage limits set forth in the Investment Company Act of 1940.

THE FUND'S REGULATORY LEVERAGE

Bank Borrowings

The Fund employs regulatory leverage through the use of bank borrowings. As of December 31, 2013, the Fund had outstanding bank borrowings of $116,000,000.

Common Share

Information

DISTRIBUTION INFORMATION

The following information regarding the Fund's distributions is current as of December 31, 2013. The Fund's distribution levels may vary over time based on the Fund's investment activities and portfolio investment value changes.

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 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.

Common Share Information (continued)

The following table provides information regarding the Fund's common share distributions and total return performance for the fiscal year ended December 31, 2013. This information is intended to help you better understand whether the Fund's returns for the specified time period were sufficient to meet its distributions.

*  Current distribution rate is based on the Fund's current annualized quarterly distribution divided by the Fund's current market price. The Fund's quarterly distributions to its shareholders may be comprised of ordinary income, net realized capital gains and, if at the end of the fiscal year the Fund's cumulative net ordinary income and net realized gains are less than the amount of the Fund's distributions, a return of capital for tax purposes.

**  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, 2008 through December 31, 2013 or for the tax years ended prior to December 31, 2006.

COMMON SHARE REPURCHASES

During November 2013, 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 shares.

As of December 31, 2013, and since the inception of the Fund's repurchase program, the Fund has cumulatively repurchased and retired common shares as shown in the accompanying table.

During the current reporting period, the Fund repurchased and retired its common shares at a weighted average price per common share and a weighted average discount per common share as shown in the accompanying table.

OTHER COMMON SHARE INFORMATION

As of December 31, 2013, and during the current reporting period, the Fund's common share price was trading at a premium/(discount) to its common share NAV as shown in the accompanying table.

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 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.

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

Counterparty Risk. To the extent that a Fund's derivative investments are purchased or sold in over-the-counter transactions, the Fund will be exposed to the risk that counterparties to these transactions will be unable to meet their obligations.

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.

Illiquid Securities Risk. This is the risk that the Fund may not be able to sell securities in its portfolio at the time or price desired by the Fund.

Below-Investment Grade Risk. Investments in securities below investment grade quality are predominantly speculative and subject to greater volatility and risk of default.

Non-U.S. Securities Risk. Investments in non-U.S securities involve special risks not typically associated with domestic investments including currency risk and adverse political, social and economic development. These risks often are magnified in emerging markets.

Real Estate Risk. The Fund may invest in various types of securities issued by real estate investment trusts (REITs), linking an investment in the Fund to the performance of the real estate markets, which may fall due to increasing vacancies, declining rents or the failure of borrowers to pay their loans.

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.

Unrated Investment Risk. In determining whether an unrated security is an appropriate investment for the Fund, the portfolio manager will consider information from industry sources, as well as its own quantitative and qualitative analysis, in making such a determination. However, such a determination by the portfolio manager is not the equivalent of a rating by a rating agency.

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.

Risks from Unsecured Adjustable Rate Loans or Insufficient Collateral Securing Adjustable Rate Loans. Some of the adjustable rate loans in which the Fund may invest will be unsecured or insufficiently collateralized, thereby increasing the risk of loss to the Fund in the event of issuer default.

Value Stock Risks. Value stocks are securities that the portfolio manager believes to be undervalued or mispriced. If the manager's assessment of a company's prospects is wrong, the price of the company's common stock or other equity securities may fall, or may not approach the value that the manager has placed on them.

Interest Rate Swaps Risk. The risk that yields will move in the direction opposite to the direction anticipated by a Fund, which would cause a Fund to make payments to its counterparty in the transaction that could adversely affect the Fund's performance.

Forward Currency Contracts Risk. Forward currency contracts are not standardized and are substantially unregulated. Principals are not required to continue to make markets in the securities or currencies they trade and these markets can experience periods of illiquidity, sometimes of significant duration. In addition, trading forward currency contracts can have the effect of financial leverage by creating additional investment exposure.

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.

Independent Registered Public Accounting Firm

The Board of Trustees and Shareholders
Nuveen Diversified Dividend and Income Fund

We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Nuveen Diversified Dividend and Income Fund (the "Fund") as of December 31, 2013, and the related statements of operations and cash flows for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2013, by correspondence with the custodian, counterparties, selling or agent banks, and brokers or by other appropriate auditing procedures where replies from selling or agent banks and brokers were not received. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Nuveen Diversified Dividend and Income Fund at December 31, 2013, and the results of its operations and its cash flows for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.
