Chair’s Letter
to Shareholders

Dear Shareholders,

The COVID-19 crisis is taking an unprecedented toll on our health, societies, economies and financial markets. Our thoughts are with all whose lives have been affected by the disease and its economic fallout. The extreme “social distancing” efforts needed to contain the coronavirus are causing a severe contraction in economic activity and amplifying market volatility, as global supply chains and consumer and business demand have been significantly disrupted. With some regions of the world having appeared to “flatten the curve” of infections, governments and public health officials face the extraordinary challenge of balancing the resumption of economic activity with public safety, in a way that minimizes the potential for a second wave of outbreaks. The spike in market volatility during March and the strong rally that followed in April may be indicative of the large swings in both directions that are likely to continue as markets digest new information and seek more clarity.

While we do not want to understate the dampening effect on the global economy, it is important to differentiate short-term interruptions from the longer-lasting implications to the economy. Some areas of the global economy were already on the mend prior to the coronavirus epidemic. Momentum could pick up again as factories come back online and consumer demand resumes once the virus is under control and temporary bans on movement and travel are lifted. Central banks and governments around the world have announced economic stimulus measures. In the U.S., the Federal Reserve has cut its benchmark interest rate to near zero and introduced programs that helped revive the U.S. economy after the 2008 financial crisis. The U.S. Government has approved three relief packages, including a $2 trillion-dollar package directly supporting businesses and individuals. The Coronavirus Aid, Relief and Economic Security Act, called the CARES Act, provides direct payments and expanded unemployment benefits to individuals, loans and grants to small businesses, loans and other money to large corporations and funding for hospitals, public health, education and state and local governments. Additional aid will likely be approved in the months ahead.

In the meantime, patience and a long-term perspective are key for investors. When market fluctuations are the leading headlines day after day, it’s tempting to “do something.” However, your long-term goals can’t be met with short-term thinking. We encourage you to talk to your financial advisor, who can review your time horizon, risk tolerance and investment goals. 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.

Sincerely,

Terence J. Toth
Chair of the Board

Portfolio Manager’s Comments

Nuveen Taxable Municipal Income Fund (NBB)

The Fund features portfolio management by Nuveen Asset Management, LLC (NAM), an affiliate of Nuveen Fund Advisors, LLC, the Fund’s investment adviser. Portfolio manager Daniel J. Close, CFA, discusses U.S. economic and municipal market conditions, key investment strategies and the twelve-month performance of the Nuveen Taxable Municipal Income Fund (NBB). Dan has managed NBB since its inception in April 2010.

What factors affected the U.S. economy and the national municipal market during the twelve-month reporting period ended March 31, 2020?

The longest economic expansion in U.S. history came to an abrupt halt in early 2020 amid the coronavirus pandemic. To slow the spread of the virus, large portions of the economy were shut down, with companies closing either temporarily or permanently and most of the U.S. population under stay-at-home orders (as of the end of March 2020). The disruption has been swift and severe, and is expected to tip the economy into recession, a several months’ long contraction across the broad economy. For the first quarter of 2020, the Bureau of Economic Analysis reported that annualized gross domestic product (GDP) shrank 4.8%, according to its “advance” estimate. GDP measures the value of goods and services produced by the nation’s economy less the value of the goods and services used up in production, adjusted for price changes. Previously, the economy had been expanding at a moderate clip. GDP grew at an annualized rate of 2.1% in the fourth quarter of 2019 and grew 2.3% in 2019 overall.

Consumer spending, the largest driver of the economy, was well supported earlier in this reporting period by low unemployment, wage gains and tax cuts. However, the coronavirus containment measures drove a significant drop in consumer spending and a sharp rise in unemployment in the final month of the quarter. The Bureau of Labor Statistics said the unemployment rate rose to 4.4% in March 2020 from 3.8% in March 2019 and job gains averaged around 118,000 per month for the past twelve months, as the economy lost 701,000 jobs in March 2020. Average hourly earnings grew at an annualized rate of 3.1% in March 2020. However, the overall trend of inflation remained subdued, and registered a notably slower rate in March 2020 due to falling gasoline prices. The Bureau of Labor Statistics said the Consumer Price Index (CPI) increased 1.5% over the twelve-month reporting period ended March 31, 2020 before seasonal adjustment.

Portfolio Manager’s Comments (continued)

Low mortgage rates and low inventory drove home prices moderately higher in this reporting period, although the most recent data do not yet reflect the shutdown. The S&P CoreLogic Case-Shiller U.S. National Home Price Index, which covers all nine U.S. census divisions, was up 4.2% year-over-year in February 2020 (most recent data available at the time this report was prepared). The 10-City and 20-City Composites reported year-over-year increases of 2.9% and 3.5%, respectively.

With economic momentum slowing in 2019 from 2018’s stronger pace, the U.S. Federal Reserve (Fed) left rates unchanged throughout the first half of 2019 then cut rates by 0.25% at each of the July 2019, September 2019 and October 2019 policy committee meetings. Markets registered disappointment with the Fed’s explanation that the rate cuts were a “mid-cycle adjustment,” rather than a prolonged easing period, and its signal that there would be no additional rate cuts in 2019. Also in the latter half of 2019, the Fed announced it would stop shrinking its bond portfolio sooner than scheduled, as well as began buying short-term Treasury bills to help money markets operate smoothly and maintain short-term borrowing rates at low levels. Fed Chairman Powell emphasized that the Treasury bill purchases were not a form of quantitative easing. The Fed continued its Treasury bill buying in January 2020, as well as left its benchmark interest rate unchanged, while noting the emerging coronavirus risks. As the outbreak spread to the U.S. and significant restrictions on social and economic activity were imposed starting in March 2020, the Fed enacted an array of emergency measures to stabilize the financial system and support the markets, including cutting its main interest rate to near zero, offering lending programs to aid small and large companies and allowing unlimited bond purchases, known as quantitative easing. Meanwhile, the U.S. government approved three aid packages, totaling more than $100 billion in funding to health agencies and employers offering paid leave and $2 trillion allocated across direct payments to Americans, an expansion of unemployment insurance, loans to large and small businesses, funding to hospitals and health agencies and support to state and local governments.

While trade and tariff policy drove market sentiment for most of the twelve-month reporting period, the outbreak of the novel coronavirus and its associated disease COVID-19 rapidly dwarfed all other market concerns as the reporting period was closing. Equity and commodity markets sold-off and safe-haven assets rallied as China, other countries and then the United States initiated quarantines, restricted travel and shuttered factories and businesses. The potential economic shock was particularly difficult to assess, which amplified market volatility.

Prior to the virus outbreak, global markets had become more bullish on the outlook for 2020 as trade policy and Brexit appeared to make progress at the end of 2019. The U.S. and China agreed on a partial trade deal, which included rolling back some tariffs, increasing China’s purchases of U.S. agriculture products and the consideration of intellectual property, technology and financial services rights. The “phase one” deal was signed on January 15, 2020. While much of the focus remained on the U.S.-China relationship, trade spats between the U.S. and Mexico, the European Union (EU), Brazil and Argentina also arose throughout the reporting period. In January 2020, the U.S. Congress fully approved the U.S., Mexico and Canada Agreement (USMCA), which replaces the North American Free Trade Agreement. With more clarity on trade deals, the trade-related deterioration in global manufacturing and export data was expected to improve. However, the COVID-19 crisis has since upended those assumptions.

Investors also remained watchful of local political dynamics around the world. In the U.K., the Conservative Party won a large majority in the December 2019 general election and Parliament passed the Brexit Bill days later, facilitating the U.K.’s exit from the EU at the end of January 2020. In Italy, the prime minister unexpectedly resigned in August 2019, and the newly formed coalition government appeared to take a less antagonistic stance towards the EU. Europe’s traditional centrist parties lost seats in the May 2019 Parliamentary elections and populist parties saw marginal gains. Europe also contended with the “yellow vest” protests in France,

immigration policy concerns, Russian sanctions and political risk in Turkey. Anti-government protests erupted across Latin America, Hong Kong and Lebanon during 2019. Venezuela’s economic and political crisis deepened. Argentina surprised the market with the return of a less market-friendly administration. Brazil’s Bolsonaro administration achieved a legislative win on pension reform and kept the economy on a path of modest growth. The ruling parties in India and South Africa maintained their majorities, where slower economic growth could complicate their respective reform mandates.

Despite the severe sell-off in March 2020, municipal bonds managed positive performance over the twelve-month reporting period. For most of the reporting period, a significant decline in interest rates drove municipal bond prices higher, with positive technical and fundamental conditions also supporting credit spread tightening. Prior to the emergence of the novel coronavirus, interest rates had been pressured lower by signs that the economy’s momentum was slowing, a more dovish central bank policy, geopolitical tensions (especially regarding trade) and bouts of equity market volatility. Then, from late February through March 2020, coronavirus risks permeated the markets, sending U.S. Treasury yields to historic lows. Rate volatility increased sharply in that six-week period. As liquidity became stressed, investors began to liquidate any asset possible, including municipal bonds. Municipal bond prices declined rapidly, amid rampant selling across both the high grade and high yield segments that was exacerbated in some cases by exchange-traded fund and closed-end fund selling. Credit spreads widened significantly during the March 2020 sell-off, ending the month above their long-term average. In the final weeks of the reporting period, monetary and fiscal interventions from the Fed and U.S. government helped the market stabilize, although prices remained meaningfully off their pre-crisis levels. The U.S. Treasury yield curve flattened overall, with a portion of the curve temporarily inverting (i.e. longer rates were lower than shorter rates, the opposite of normal) from late August 2019 to late September 2019. The municipal yield curve also flattened overall, during the first 11 months of the reporting period, as yields on longer maturities fell more than those of shorter maturities.

Prior to the market turmoil in March 2020, municipal bond gross issuance nationwide had been robust. The overall low level of interest rates encouraged issuers to continue to actively refund their outstanding debt. In these transactions the issuers are issuing new bonds and taking the bond proceeds and redeeming (calling) old bonds. These refunding transactions have ranged from 30% to 60% of total issuance over the past few years. Thus, the net issuance (all bonds issued less bonds redeemed) is actually much lower than the gross issuance. So, while gross issuance volume has been adequate, the net has not and this was an overall positive technical factor on municipal bond investment performance in recent years. Notably, taxable municipal bond issuance increased meaningfully in 2019. The Tax Cut and Jobs Act of 2017 prohibits municipal issuers from issuing new tax-exempt bonds to pre-refund existing tax-exempt bonds. However, municipalities have taken advantage of the low interest rate environment and the strong demand for yield to issue taxable municipal debt, enabling them to save on net interest costs.

Demand for municipal bonds was strong for most of this reporting period. Municipal bond funds took in consistently positive cash flows in calendar year 2019 and the first two months of 2020. However, fund flows turned more volatile in March 2020, as markets began to digest the coronavirus impact. Low interest rates in the U.S. and globally have continued to drive investors toward higher after-tax yielding assets, including U.S. municipal bonds. Additionally, as tax payers have begun to assess the impact of the 2017 tax law, which caps the state and local tax (SALT) deduction for individuals, there has been increased demand for tax-exempt municipal bonds in 2019 to date, especially in states with high income taxes and/or property taxes.

Portfolio Manager’s Comments (continued)

What key strategies were used to manage the Fund during the twelve-month reporting period ended March 31, 2020?

The Fund’s primary investment objective is to provide current income through investments in taxable municipal securities. The Fund’s secondary investment objective is to seek enhanced portfolio value and total return. The Fund seeks to achieve its investment objective by investing primarily in a diversified portfolio of taxable municipal securities, which make up approximately 80% of its managed assets. Under normal circumstances, the Fund may invest 20% of its managed assets in securities other than taxable municipal securities including tax-exempt municipal securities, U.S. Treasury and other U.S. government agency securities. At least 80% of the Fund’s managed assets will be invested in securities that are investment grade quality at the time of purchase, as rated by at least one independent rating agency or judged to be of comparable quality by NAM. In addition, the Fund will use an integrated leverage and hedging strategy so that the Fund has the potential to enhance income and risk-adjusted total return over time. The Fund may employ leverage instruments such as bank borrowings, including loans from certain financial institutions, and portfolio investments that have the economic effect of leverage, including investments in inverse floating rate securities.

For most of the reporting period, a favorable macroeconomic backdrop, strong demand, narrowing credit spreads and falling interest rates supported municipal bond performance. We would also point out that taxable municipal bond issuance increased meaningfully beginning in 2019. The Tax Cut and Jobs Act of 2017 prohibits municipal issuers from issuing new tax-exempt bonds to pre-refund existing tax-exempt bonds. Instead, municipalities have taken advantage of the low interest rate environment and the strong demand for yield to issue taxable municipal debt, enabling them to save on net interest costs. However, the coronavirus pandemic and the shutdown of the economy introduced significant uncertainty about the future of economic growth and impact to municipal credit fundamentals. As the nearer-term impacts began to materialize, we looked for relative value and income enhancement opportunities among credits we believe may demonstrate resilience over the long term.

In addition to the bonds bought in the first half of the reporting period (detailed in the Fund’s semiannual report dated September 30, 2019), we added three public utilities, a newly issued airport, two dedicated tax bonds (Dallas Area Rapid Transit and Salt Lake County Convention Center), a public higher education (Northern Arizona University), a health care (Westchester County Health Care in New York), a non-rated port (Illinois Ports) and two high profile new issues (Grand Parkway Toll Road in Texas and Gladstone Institutes in California). We also took advantage of price dislocations in the market after the sell-off to add New York MTA (Metropolitan Transportation Authority) bonds, which appeared undervalued considering the importance of the transit system to New York City and the importance of New York City’s economy to the national economy. Maturing and called bonds provided most of the proceeds to invest in these new purchases. We also sold some short call, high credit quality structures to fund new buying. At the end of March 2020, we sold a modest amount of pre-refunded bonds and collapsed a tender option bond trust backed by pre-refunded bonds to pay down reverse repo leverage (see reverse repurchase agreements in the Fund Leverage section of this report). This kept the Fund’s longer-term investment positioning intact.

How did the Fund perform over the twelve-month reporting period ended March 31, 2020?

The table in the Fund's Performance Overview and Holding Summaries section of this report provides the Fund’s total returns for the one-year, five-year and since-inception periods ended March 31, 2020.

The Fund's total returns are compared with the performance of the corresponding market indexes. For the twelve-month reporting period ended March 31, 2020, the total returns on common share net asset value (NAV) for NBB underperformed the return for the Bloomberg Barclays Taxable Municipal Long Bond Index.

The largest driver of relative underperformance was the Fund’s exposure to interest rate futures and swaps. As part of its approach to investing, the Fund uses an integrated leverage and hedging strategy in an effort to enhance current income and total return, while working to maintain a level of interest rate risk similar to that of the Bloomberg Barclays Taxable Municipal Long Bond Index. As part of this integrated strategy, NBB used inverse floating rate securities and reverse repurchase agreements (also known as reverse repos) as leverage to potentially magnify performance. During this reporting period, the Fund used interest rate swaps to reduce their leverage-adjusted durations to a level close to that of the Bloomberg Barclays Taxable Municipal Long Bond Index. In addition, the Fund entered into staggered interest rate swaps to partially set the interest cost of leverage. The speed and magnitude of the credit spread widening during the March 2020 sell-off was a considerable headwind to the Fund’s strategy of owning credit spread exposure on a leveraged basis. Leverage is discussed in more detail later in this report. The Fund also managed the duration of its portfolio by shorting interest rate futures contracts, which had a negative impact on performance during the reporting period as Treasury yields rallied significantly in March 2020.

We use these strategies to help manage the portfolio's duration and enhance income, along with the allocation of bonds by effective duration. In this reporting period, our duration positioning detracted from relative performance due to an overweight to the zero to 2-year effective durations, which were the weakest performing segment, and an underweight to the longest effective durations, which were outperformers.

Credit quality positioning was also detrimental during this reporting period. The Fund’s exposure to single B rated bonds, which are primarily tobacco securitization bonds, was unfavorable, as the late February to March 2020 period saw rampant selling in high yield (including single B) and tobacco credits.

Sector performance was relatively neutral overall. The best performing sectors for the Fund included higher credit quality, essential services sectors such as water and sewer and electric utilities. However, the positive results were offset by toll roads, ports and special tax bonds, which detracted from performance. Although special tax bonds modestly outperformed the broad market, the Fund’s exposure was negatively affected by the underperformance of credits associated with hotel occupancy taxes (for example, a convention center). However, our overall credit selection was favorable to performance, largely due to the strong performance of tender option bond positions.

Fund Leverage

IMPACT OF THE FUND’S LEVERAGE STRATEGY ON PERFORMANCE

One important factor impacting the returns of the Fund’s common shares relative to its comparative benchmark was the Fund’s use of leverage through reverse repurchase agreements and investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. The Fund used leverage because our research has shown that, over time, leveraging provides opportunities for additional income. The opportunity arises when short-term rates that a Fund pays on its leveraging instruments are lower than the interest the Fund earns on its portfolio of long-term bonds that it has bought with the proceeds of that leverage. This has been particularly true in the recent market environment where short-term rates have been low by historical standards.

However, use of leverage can expose Fund common shares to additional price volatility. When the Fund uses leverage, the Fund’s common shares will experience a greater increase in their net asset value if the municipal bonds acquired through the use of leverage increase in value, but will also experience a correspondingly larger decline in their net asset value if the bonds acquired through leverage decline in value, which will make the shares’ net asset value more volatile, and total return performance more variable, over time.

In addition, common share income in levered funds will typically decrease in comparison to unlevered funds when short-term interest rates increase and increase when short-term interest rates decrease. In recent quarters, fund leverage expenses have generally tracked the overall movement of short-term tax-exempt interest rates. While fund leverage expenses are somewhat higher than their all-time lows after the 2007-2009 financial crisis, which has contributed to a reduction in common share net income and long-term total return potential, leverage nevertheless continues to provide the opportunity for incremental common share income. Management believes that the potential benefits from leverage continue to outweigh the associated increase in risk and volatility previously described.

NBB’s use of leverage had a negative impact on total return performance during this reporting period.

As of March 31, 2020, the Fund’s percentages of leverage are as shown in the accompanying table.

The Fund seeks to pay regular monthly dividends out of its net investment income at a rate that reflects its past and projected net income performance. To permit the Fund to maintain a more stable monthly dividend, the Fund may pay dividends at a rate that may be more or less than the amount of net income actually earned by the Fund during the period. Distributions to common shareholders are determined on a tax basis, which may differ from amounts recorded in the accounting records. In instances where the monthly dividend exceeds the earned net investment income, the Fund would report a negative undistributed net ordinary income. Refer to Note 6 – Income Tax Information for additional information regarding the amounts of undistributed net ordinary income and undistributed net long-term capital gains and the character of the actual distributions paid by the Fund during the period.

During the current fiscal period, the Fund’s distributions were slightly greater than the Fund’s interest income, net of Fund expenses. As a result a portion of the Fund’s distributions were deemed to be a return of capital. For financial reporting purposes, the composition and per share amounts of the Fund’s dividends for the reporting period are presented in this report’s Statement of Changes in Net Assets and Financial Highlights, respectively. For income tax purposes, distribution information for the Fund as of its most recent tax year end is presented in Note 6 — Income Tax Information within the Notes to Financial Statements of this report.

The following table presents the regular, monthly distributions for the Fund for the current fiscal period. The final determinations of the source and characteristics of all distributions will be made in early 2021 and reported to shareholders on Form 1099-DIV at that time.

 

CHANGE IN METHOD OF PUBLISHING NUVEEN CLOSED-END FUND DISTRIBUTION AMOUNTS

During November 2019, the Nuveen Closed-End Funds discontinued the practice of announcing Fund distribution amounts and timing via press release. Instead, information about the Nuveen Closed-End Funds’ monthly and quarterly periodic distributions to shareholders will be posted and can be found on Nuveen’s enhanced closed-end fund resource page, which is at www.nuveen.com/closed-end-fund-distributions, along with other Nuveen closed-end fund product updates. Shareholders can expect regular distribution information to be posted on www.nuveen.com on the first business day of each month. To ensure that our shareholders have timely access to the latest information, a subscribe function can be activated at this link here, or at this web page (www.nuveen.com/en-us/people/about-nuveen/for-the-media).

COMMON SHARE REPURCHASES

During August 2019, the Fund’s Board of Trustees reauthorized an open-market share repurchase program, allowing the Fund to repurchase an aggregate of up to approximately 10% of its outstanding shares.

As of March 31, 2020, and since the inception of the Fund’s repurchase program, the Fund has cumulatively repurchased and retired its outstanding common shares as shown in the accompanying table.

 

During the current reporting period, the Fund did not repurchase any of its outstanding common shares.

OTHER COMMON SHARE INFORMATION

As of March 31, 2020, and during the current reporting period, the Fund’s common share prices were 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.

Nuveen Taxable Municipal Income Fund (NBB)

Investing in closed-end funds involves risk; principal loss is possible. There is no guarantee the Fund’s investment objectives will be achieved. Closed-end fund shares may frequently trade at a discount or premium to their net asset value. Debt or fixed income securities such as those held by the Fund, are subject to market risk, credit risk, interest rate risk, derivatives risk, liquidity risk, and income risk. As interest rates rise, bond prices fall. Lower credit debt securities may be more likely to fail to make timely interest or principal payments. The Fund’s investments in Build America Bonds, which were discontinued in 2010, subject the Fund to tax risk, liquidity risk, and may negatively affect the Fund’s performance. Leverage increases return volatility and magnifies the Fund’s potential return and its risks; there is no guarantee a fund’s leverage strategy will be successful. These and other risk considerations such as inverse floater risk, and tax risk are described in more detail on the Fund’s web page at www.nuveen.com/NBB.
