Chair’s Letter to Shareholders

Dear Shareholders,

More than a year has passed since the World Health Organization declared COVID-19 a global pandemic in March 2020: a year of global economic recession, financial market turbulence and some immeasurable losses. A year later the health crisis persists but the widespread distribution of vaccines in the U.S. is enabling us to look forward to what our “new normal” might be. In the meantime, extraordinary economic interventions by governments and central banks around the world are helping to bridge the gap.

With vaccine progress and economic stimulus beginning to provide real benefits to the global economy, markets are anticipating a strong rebound in growth, especially in the U.S. To extend relief programs enacted earlier in the crisis, the U.S. government passed $900 billion in aid to individuals and businesses in late December 2020. Another $1.9 trillion relief package was signed into law in March 2021 providing extended unemployment benefits, direct payments to individuals and families, assistance to state and local municipalities, grants to education and public health, and other support. Additional stimulus proposals are set to be discussed in Congress. The U.S. Federal Reserve, along with other central banks around the world, has pledged to keep monetary conditions accommodative for as long as necessary, as they consider the recent increase in inflation risks as transitory.

While the markets’ longer-term outlook has brightened, we expect intermittent bouts of volatility to continue. COVID-19 cases are still elevated in some regions, as more virulent strains have spread and vaccination rollouts have been uneven around the world. The recovery hinges on controlling the virus, and estimates vary considerably on when economic activity might be fully restored. Achieving sufficient inoculation of the population depends on many variables, including logistics, public confidence, real-world efficacy and the emergence of variant virus strains, as well as whether young children can safely and effectively be vaccinated. In the U.S., the recent slowdown in vaccine demand is prompting a shift from mass distribution to outreach. On the political front, the Biden administration’s full policy agenda and the potential for Congressional gridlock remain to be seen, either of which could cause investment outlooks to shift. Short-term market fluctuations can provide your Fund opportunities to invest in new ideas as well as upgrade existing positioning while providing long-term value for shareholders. For more than 120 years, the careful consideration of risk and reward has guided Nuveen’s focus on delivering long-term results to our shareholders.

If you have concerns about what’s coming next, it can be an opportune time to assess your portfolio. We encourage you to review your time horizon, risk tolerance and investment goals with your financial professional. 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 Managers’ Comments (continued)

growing at an annualized rate of 6.4% according to the Bureau of Economic Analysis “advance” estimate, an increase from 4.3% (annualized) in the fourth quarter of 2020. 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.

Although, consumer spending, the largest driver of the economy, remained resilient despite the disruption caused by the health and economic crisis, it declined significantly as unemployment rose sharply starting in March 2020. These measures rebounded markedly in the second half of 2020, although the momentum slowed toward the end of 2020 amid a resurgence of COVID-19 infections. As of March 2021, slightly more than half of the 22 million jobs lost in March and April 2020 have been recovered resulting in an unemployment rate of 6.0% in March 2021 as reported by the Bureau of Labor Statistics, up from 4.4% in March 2020. The average hourly earnings rate increased, growing at an annualized rate of 4.2% in March 2021, despite the spike in unemployment. Earnings data was skewed by the concentration of job losses in lower-wage work, which effectively eliminated most of the low-wage data, resulting in an average of mostly higher numbers. The overall trend of inflation accelerated, largely due to rising energy prices and the improving economy. The higher annual inflation rate in March 2021 is also the result of the comparison from a year ago, when consumer prices fell sharply as the first lockdowns were imposed in March 2020. The Bureau of Labor Statistics said the Consumer Price Index (CPI) increased 2.6% over the twelve-month reporting period ended March 31, 2021, before seasonal adjustment.

With the onset of the COVID-19 crisis, the Federal Reserve (Fed) enacted an array of emergency measures in March 2020 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. In August 2020, the Fed announced a change in its inflation targeting policy, moving from a program of absolute targeting to an average inflation targeting policy. Under this regime, the Fed will tolerate the inflation rate temporarily overshooting the target rate to offset periods of below-target inflation, so that inflation averages a 2% target rate over time. Fed officials remained cautious, acknowledging the economy’s significant improvement from the COVID-19 recession but also expressing concerns about near-term weakness, and left monetary policy unchanged over the remainder of their meetings in 2020 and early 2021.

The federal government also intervened with historic relief measures, starting with three aid packages in March and April 2020. These included $2 trillion allocated across direct payments to individuals, an expansion of unemployment insurance, loans to large and small businesses, funding to hospitals and health agencies and support to state and local governments, and more than $100 billion in funding to employers offering paid leave. In December 2020, the government enacted a $900 billion relief package extending some of these programs, and followed in March 2021 with another $1.9 trillion deal providing support to individuals and families, small businesses, state and local governments, education and public health/vaccination. The Biden administration has proposed another $2 trillion stimulus plan focused on infrastructure and jobs. However, the plan is expected to face legislative hurdles.

The COVID-19 crisis rapidly dwarfed all other market concerns starting in late February 2020. Equity and commodity markets sold off and safe-haven assets rallied in March 2020 as countries initiated quarantines, restricted travel and shuttered factories and businesses. The potential economic shock was particularly difficult to assess at the time, which amplified market volatility. An ill-timed oil price war between the Organization of the Petroleum Exporting Countries (OPEC) and non-OPEC member Russia, which caused oil prices to plunge in March 2020, exacerbated the market sell-off. At year end, the announcement of high efficacy rates in several COVID-19 vaccine trials, followed by regulatory authorizations and public vaccination drives across Western countries, improved the outlook for 2021 and led to risk-on sentiment in the markets. However, market volatility picked up in early 2021, as a stronger economic outlook and improving vaccination rates led to rising inflation concerns and an increase in long-term interest rates.

Geopolitical uncertainty remained elevated during 2020 in anticipation of the U.S. presidential election in November 2020 and the Brexit transition period set to expire in December 2020. However, political risks began to ease with the election of President Joe Biden and a final deal struck between the European Union and U.K. before the end of the transition period. Although China and the U.S. signed a “phase one” trade deal in January 2020, tensions continued to flare over other trade and technology/security issues, Hong Kong’s sovereignty and the management of the COVID-19 crisis.

market was beginning to stabilize after coronavirus risks drove U.S. Treasury yields to historic lows and rate volatility increased sharply, especially from late February to the end of March 2020. In that six-week period, as liquidity became stressed, investors began to liquidate any asset possible, including municipal bonds. Municipal bond prices declined rapidly (and yields spiked higher), 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. Municipal bond prices became severely dislocated from Treasury prices. Credit spreads widened significantly during the March 2020 sell-off, ending the month above their long-term average. Ongoing monetary and fiscal interventions from the Fed and U.S. government helped the market stabilize, then recover over the course of 2020 and early 2021.

The municipal yield curve steepened over this reporting period, initially driven by a pronounced drop in yields at the short end of the curve. Then a new steepening cycle began in early 2021 as markets priced in a stronger economic recovery and higher inflation, fueled by increasing vaccination rates and more federal stimulus, which drove longer-term interest rates higher.

Municipal bond gross issuance nationwide remained strong in the reporting period, with deals postponed rather than canceled during the COVID-19 driven sell-off. The overall low level of interest rates has 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. This lower net issuance was an overall positive technical factor on municipal bond investment performance in recent years. Notably, taxable municipal bond issuance has increased meaningfully since the advent of the Tax Cut and Jobs Act of 2017, which 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 while adding to the scarcity value of tax-exempt issues.

While municipal bond funds suffered significant outflows in March 2020, particularly from high yield municipal bond funds, fund flows rebounded strongly over the remainder of 2020 and sustained a robust pace through early 2021. Demand has been resilient even though municipal defaults, as expected, have increased somewhat during the COVID-19 crisis. However, default activity has occurred mainly in sectors with greater COVID-19 risk exposure, such as senior living, corporate-backed and real estate-backed. Moreover, while there are some pockets of municipal credit ratings stress, a wave of downgrades has not materialized. With interest rates in the U.S. and globally still near all-time lows, even after the recent increase in long-term rates, the appetite for yield has continued to drive investors toward higher after-tax yielding assets, including U.S. municipal bonds. Additionally, as tax payers have adjusted to 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, especially in states with high income taxes and/or property taxes.

How did the Funds perform during the twelve-month reporting period ended March 31, 2021?

The tables in the Fund Performance, Expense Ratios and Effective Leverage Ratios section of this report provide each Fund’s total return performance information for each share class of the Fund for the period ended March 31, 2021. Each Fund’s Class A Shares at net asset value (NAV) are compared with the performance of its corresponding benchmark and Lipper classification average.

During the reporting period, all four Funds outperformed their respective benchmark indexes. The Nuveen Intermediate Duration Municipal Bond Fund performed in line with its Lipper classification average, while the other three Funds outperformed their Lipper classification average to varying degrees.

What strategies were used to manage the Funds and how did these strategies influence performance during the twelve-month reporting period ended March 31, 2021?

The investment objective of Nuveen All-American Municipal Bond Fund, Nuveen Intermediate Duration Municipal Bond Fund and Nuveen Limited Term Municipal Bond Fund is to provide as high a level of current interest income exempt from regular federal income taxes as is consistent with preservation of capital. Nuveen Short Term Municipal Bond Fund’s investment objective is to provide current income that is exempt from federal income tax to the extent consistent with preservation of capital.

Portfolio Managers’ Comments (continued)

Below we highlight the specific factors influencing each Fund’s investment strategy, as well as how each Fund's portfolio was managed in light of recent market conditions.

Nuveen All-American Municipal Bond Fund

The Nuveen All-American Municipal Bond Fund’s Class A Shares at NAV outperformed the S&P Municipal Bond Index for the twelve-month reporting period ended March 31, 2021.

Favorable security selection was the biggest driver of the Fund’s relative outperformance this reporting period. The Fund’s top individual contributors included Chicago Board of Education general obligation and capital improvement tax bonds, as well as Ohio tobacco bonds. These tobacco bonds rallied more strongly than the index amid investors’ renewed appetite for higher yielding securities in an improving fundamental and economic environment.

Other top performers contributing to the Fund’s relative performance included bonds for Brightline (formerly known as Virgin Trains USA), a South Florida high-speed passenger rail project and for Metropolitan Pier and Exposition Authority, which owns tourist destination Navy Pier and the McCormick Place convention center in Chicago. In both cases, the bonds recovered as investors became more optimistic about their potential to weather the COVID-19 crisis.

Holdings in Energy Harbor equity (formerly FirstEnergy Solutions) also fared well. The Fund acquired shares in Energy Harbor when its holding of certain municipal bonds issued by FirstEnergy Solutions was converted into Energy Harbor equity as part of FirstEnergy Solutions’ emergence from bankruptcy protection. Although this position underperformed for the Fund overall in the first half of the reporting period, it bounced back strongly in the second half and contributed meaningfully to the Fund’s result.

Partially offsetting these positive security selection results, however, were the Fund’s positions in project revenue bonds backed by specialty cancer treatment centers Georgia Proton Treatment Center and Provision CARES Proton Therapy Center (Florida). The positions underperformed the index as both centers continued to struggle amid the COVID-19 crisis.

The Fund’s duration (interest rate) and yield curve positioning also contributed to performance. The Fund was overweight in longer dated bonds (particularly 22 years and more), which helped the Fund maintain its yield. These securities outperformed the benchmark as municipal interest rates declined through most of the reporting period. An underweight in shorter-dated securities was also helpful, since these lagged longer-term bonds.

The Fund's sector positioning was another positive performance factor, which included the Fund’s overweight in higher yielding segments that bounced back particularly strongly from the market’s March 2020 lows. The Fund had more exposure than the benchmark to the tobacco, industrial development revenue, health care, airport and transportation sectors, all of which outperformed the index. Additionally, being underweight in the state and local general obligation and pre-refunded sectors also contributed to the Fund's performance, given that these generally higher quality categories tended to generate smaller gains. However, an underweight in utility bonds modestly detracted from performance.

The Fund's credit quality was well positioned. It helped to be overweight bonds rated lower investment grade (A and BBB) and below investment grade (BB and below, including non-rated bonds). Bonds in these credit rating tiers outpaced higher grade issues (AAA and AA rated), in which the Fund was underweight.

Early in the reporting period, the Fund, mirroring the broad municipal bond Fund market, experienced investment outflows following the steep market decline in mid-March 2020. To satisfy these shareholder redemptions, management sold higher quality, shorter duration bonds, which had held more of their value than comparable lower quality, longer dated issues during the market’s early spring 2020 decline. With these sales, made at a loss, management harvested tax losses, enhanced the Fund’s income earning capability and sought to make the portfolio more tax efficient.

As the municipal market exhibited signs of stabilization by mid-spring 2020, management’s focus quickly shifted toward relative value opportunities. It exchanged certain lower yielding bonds for similar higher yielding securities with attractive valuations, often from the same issuer.

Table of Contents

When the municipal market stabilized further and shareholder inflows returned to the Fund by May 2020, management became active purchasers of opportunities it identified in the marketplace, particularly among lower quality bonds deemed creditworthy. In doing so, it built the Fund’s allocation to both lower investment grade and below investment grade bonds deemed creditworthy. Typically, new bond acquisitions also were longer dated securities.

The Fund managed the duration of its portfolio by shorting interest rate future contracts. The interest rate futures had a positive impact on performance during the reporting period. The Fund’s use of certain floating rate securities, including tender option bonds (TOBs), modestly boosted relative performance.

Nuveen Intermediate Duration Municipal Bond Fund

The Nuveen Intermediate Duration Municipal Bond Fund’s Class A Shares at NAV outperformed the S&P Municipal Bond Intermediate Index for the twelve-month reporting period ended March 31, 2021.

After a market driven by the COVID-19 crisis that occurred several weeks before the start of this reporting period, municipal bond prices bounced back strongly. The municipal market benefited from significant monetary and fiscal support, optimism about safe and effective COVID-19 vaccines and continued economic recovery. Credit spreads narrowed and longer maturity bonds outperformed shorter maturity bonds as interest rates dropped and the yield curve steepened.

Credit and sector positioning helped the Fund outperform the index. In terms of credit quality, the Fund had large overweights in bonds rated lower investment grade (A and BBB) and, to a lesser extent, those rated below investment grade (below BBB). Because lower rated bonds generally outperformed higher rated bonds, this positioning aided relative performance.

The Fund's sector positioning benefited from relative overweights in various outperforming sectors, all of which outperformed the index. The Fund similarly benefited from having a lower allocation to tax-supported and utility bonds, two lagging sectors this reporting period.

Counterbalancing those positive sector related results, however, was the Fund's overweight in pre-refunded bonds. With their short durations and high credit quality, these bonds were relative underperformers in a market environment favoring securities with the opposite characteristics. An overweight in housing bonds also detracted from performance. This category underperformed as historically low interest rates increased the likelihood these bonds would be redeemed early as homeowners refinanced their mortgages.

Duration (interest rate) positioning was another overall positive performance factor. The Fund's portfolio average duration was about a year longer than that of the index, the Fund captured more of the beneficial effects of falling interest rates during the reporting period.

In contrast, security selection hurt the Fund’s overall relative performance. Certain industrial development revenue bond holdings, primarily those of some weaker performing investor owned utilities, trailed the index. Other positions to generate below index returns included higher quality, shorter maturity bonds of several large, well established, financially stable universities. Also, within the health care sector, bonds of Tower Health, a Pennsylvania-based hospital system and Louisiana-based Lake Charles Memorial Hospital were underperforming even before the COVID-19 crisis struck and continued to experience some financial stress this reporting period.

With many other individual holdings, however, the Fund experienced strong results, as various lower rated bonds recovered off depressed valuations. One such contributor was the Fund's position in the equity securities of Energy Harbor (formerly FirstEnergy Solutions). The Fund acquired shares in Energy Harbor when its holding of certain municipal bonds issued by FirstEnergy Solutions was converted into Energy Harbor equity as part of FirstEnergy Solutions’ emergence from bankruptcy protection. Although this position underperformed for the Fund overall in the first half of the reporting period, it bounced back strongly in the second half and contributed meaningfully to the Fund’s performance.

Other notable individual contributors included bonds that benefited from improved investor sentiment and confidence in issuers’ underlying credit quality. These included tobacco bonds that experienced unusually strong demand or that were well positioned on the yield curve and prepaid-gas bonds, which benefited from an improving outlook for the banks that support these loans, as well as strong performing tax-supported bonds associated with the State of Illinois and City of Chicago, the State of New Jersey and the U.S.

territory of Puerto Rico. Additional individual contributors included various transportation bonds, longer-maturity state single-family loans and certain other credits whose prospects improved along investors’ outlook. This last category included bonds for the American Dream retail and entertainment project in the Meadowlands (New Jersey), Orlando Tourist Development Tax revenue bonds and New Jersey Motor Vehicle Surcharge revenue bonds.

New purchases during the reporting period included bonds with shorter durations. This preference originated from the limited upside potential longer duration bonds were providing amid historically low interest rates. Also, entering this reporting period, the Fund’s duration was a bit longer than preferred because the Fund had previously sold shorter dated bonds to meet COVID-19 crisis driven outflows. However, once the Fund began experiencing investment inflows early in this reporting period, the Fund used the proceeds, alongside those of bond calls and maturities, to buy bonds at the shorter end of its typical range.

Similarly, with credit spreads unusually tight, the Fund bought higher quality bonds over their lower quality counterparts. This emphasis reflected a combination of available supply and that higher rated bonds were often offering a better risk/reward trade-off for shareholders. However, when attractive lower rated opportunities presented themselves the Fund invested in those credits that provided good long-term opportunity for shareholders.

Nuveen Limited Term Municipal Bond Fund

The Nuveen Limited Term Municipal Bond Fund’s Class A Shares at NAV outperformed the S&P Municipal Bond Short-Intermediate Index for the twelve-month reporting period ended March 31, 2021.

During the reporting period, municipal bond prices rose along with significant economic stimulus, increased confidence about the effectiveness of COVID-19 vaccines and ongoing evidence of a recovering economy. In this environment, falling interest rates boosted bonds, especially longer dated issues. Lower rated securities generally outperformed higher rated securities, as investors became more willing to assume credit risk as the outlook for the economy improved.

For the reporting period, the Fund’s relative performance benefited most from favorable credit and sector allocation. The Fund's large overweight in bonds with lower investment grade credit ratings (A and BBB) contributed the most, reflecting investors’ increased comfort with credit risk.

In sector terms, the Fund benefited from being overweight in several outperforming categories. Having more exposure relative to the index in the industrial development revenue, tobacco, transportation and health care sectors all contributed to results. The Fund's underweight in tax-supported and utilities sectors also added relative value. The Fund, however, was overweight in pre-refunded bonds, which lagged the index due to their high credit quality and short durations, two out-of-favor characteristics during this reporting period. Another negative performance factor was the Fund’s overweight in housing bonds, as these bonds underperformed due to their elevated risk of being redeemed early, as low interest rates encouraged more homeowners to refinance their mortgages.

Duration (interest rate) positioning also contributed to the Fund’s relative performance as the Fund's portfolio duration was somewhat longer than that of the benchmark. The Fund benefited to a greater extent from the decline in municipal interest rates during the reporting period.

Overall, security selection was a modestly negative performance factor. Certain investor owned utility holdings generated below index returns. In addition, some shorter maturity issues of high quality, well regarded universities similarly underperformed the benchmark. Also, in the health care sector, the Fund's position in bonds of Pennsylvania-based hospital system Tower Health lagged, as the issuer continued to face financial challenges as the COVID-19 crisis worsened.

One of the Fund's stronger contributor was a position in the equity securities of Energy Harbor (formerly FirstEnergy Solutions). The Fund acquired shares in Energy Harbor when its holding of certain municipal bonds issued by FirstEnergy Solutions was converted into Energy Harbor equity as part of FirstEnergy Solutions’ emergence from bankruptcy protection. Although this position underperformed for the Fund overall in the first half of the reporting period, it bounced back strongly in the second half of the reporting period and contributed meaningfully to the Fund’s result.

Table of Contents

Other notable contributors for the Fund included various utility bonds, led by prepaid-gas and Puerto Rico Aqueduct and Sewer Authority bonds, tobacco bonds that benefited from favorable yield curve positioning or otherwise strong investor demand and tax-supported credits rising on perceived improvement in issuers’ credit quality and increased optimism about the direction of the COVID-19 crisis. These latter holdings included bonds of the State of Illinois, the City of Chicago and the State of New Jersey, as well as sales-tax bonds of Puerto Rico.

During the reporting period, the Fund's new purchase activity focused on shorter duration bonds found in a low interest rate environment, that were offering a better risk/reward trade-off than the longer duration bonds within the Fund's investment universe. The Fund also purchased various short-term notes, particularly in the first half of the reporting period, when borrowers needing cash were offering buyers more attractive terms.

Given historically tight credit spreads, the Fund purchased higher quality bonds more often than lower quality bonds, whose valuations were relatively less attractive. However, the Fund did take advantage of certain opportunities to buy lower rated bonds across various sectors whenever compelling opportunities became available.

Nuveen Short Term Municipal Bond Fund

The Nuveen Short Term Municipal Bond Fund’s Class A Shares at NAV outperformed the S&P Municipal Bond Short Index for the twelve-month reporting period ended March 31, 2021.

Credit quality positioning lifted the Fund’s performance compared with the index. An overweight in bonds with lower investment grade credit ratings (A and BBB) added value as these securities combined relatively higher yields with capital appreciation due to rising bond prices. The Fund had a corresponding underweight in the highest credit quality tiers (AAA and AA), which lagged their lower grade counterparts during this reporting period.

Sector positioning also contributed to the Fund’s performance. A relative underweight in the pre-refunded bond category boosted performance, as these short maturity, high quality securities underperformed in a market environment that favored longer maturity, lower quality bonds. An overweight in several outperforming sectors, including the health care, transportation (mostly airports), prepaid-gas and industrial development revenue sectors, additionally drove the Fund’s performance.

Duration (interest rate) and yield curve positioning had a mixed performance impact. The Fund’s duration was slightly longer than the index, adding to relative performance as rates declined overall for the reporting period. The Fund also benefited from bonds with maturities exceeding four years because the index includes few bonds with this maturity profile. In contrast, the Fund’s overweight in bonds with a duration of less than one year, an underperforming category, hampered performance.

Throughout the reporting period, the Fund’s duration remained slightly above two years. New purchases primarily ranged from bonds with maturities from one to six years. Exposure slightly grew to bonds with effective durations exceeding four years. When demand for lower duration investments is strong, as it was at time during the reporting period, bonds with an extra year or two of maturity can often provide meaningful additional yield in a low interest rate environment, especially within the short-term investment universe.

The Fund maintained its strategy of attempting to add to bonds or sectors that were lagging relative to other market areas. However, because credit spreads generally did continue to tighten and normalize throughout the reporting period, there were fewer opportunities to execute this strategy toward the end of the reporting period.

New portfolio additions this reporting period included increases to the Fund’s health care exposure, as debt in this sector continued to offer reasonable incremental yield advantages. In other market areas, however, credit spreads appeared to more than fully recover, which made those sectors less attractive for further investment. Credit spreads among airport bonds recovered during the reporting period, which allowed the Fund’s weighting in this sector to drift somewhat lower. Instead, management believe many general obligation bonds were often better values and the Fund increased its weighting in that sector relative to the prior twelve-month reporting period.

Each 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 each 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 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.

Risk Considerations and Dividend Information (continued)

All monthly dividends paid by Nuveen All-American Municipal Bond Fund, Nuveen Intermediate Duration Municipal Bond Fund and Nuveen Short Term Municipal Bond Fund during the current reporting period were paid from net investment income. If a portion of the Fund’s monthly distributions is sourced or comprised of elements other than net investment income, including capital gains and/or a return of capital, shareholders will be notified of those sources. For financial reporting purposes, the per share amounts of the Fund’s distributions for the reporting period are presented in this report’s Financial Highlights. 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.

Special Dividend Information for Nuveen Limited Term Municipal Bond Fund

The Nuveen Limited Term Municipal Bond Fund seeks to pay regular monthly distributions at a level rate that reflects past and projected net income of the Fund. During the current fiscal period, the Fund’s distributions were 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 tax purposes at the fiscal year-end, which is identified in the table below.

Fund Performance, Expense Ratios and Effective Leverage Ratios

The Fund Performance, Expense Ratios and Effective Leverage Ratios for each Fund are shown within this section of the report.

Fund Performance

Returns quoted represent past performance, which is no guarantee of future results. Investment returns and principal value will fluctuate so that when shares are redeemed, they may be worth more or less than their original cost. Current performance may be higher or lower than the performance shown.

Total returns for a period of less than one year are not annualized (i.e. cumulative returns). Since inception returns are shown for share classes that have less than 10-years of performance. Returns at net asset value (NAV) would be lower if the sales charge were included. Returns assume reinvestment of dividends and capital gains. For performance, current to the most recent month-end visit nuveen.com or call (800) 257-8787.

Returns do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. Income is generally exempt from regular federal income taxes. Some income may be subject to state and local income taxes and to the federal alternative minimum tax. Capital gains, if any, are subject to tax.

Returns may reflect fee waivers and/or expense reimbursements by the investment adviser during the periods presented. If any such waivers and/or reimbursements had not been in place, returns would have been reduced. See Notes to Financial Statements, Note 7—Management Fees and Other Transactions with Affiliates for more information.

Returns reflect differences in sales charges and expenses, which are primarily differences in distribution and service fees, and assume reinvestment of dividends and capital gains.

Comparative index and Lipper return information is provided for Class A Shares at NAV only.

Expense Ratios

The expense ratios shown are as of the Fund's most recent prospectus. The expense ratios shown reflect total operating expenses (before fee waivers and/or expense reimbursements, if any). The expense ratios include management fees and other fees and expenses. Refer to the Financial Highlights later in this report for the Fund's expense ratios as of the end of the reporting period.

Effective Leverage Ratios

Leverage is created whenever a Fund has investment exposure (both reward and/or risk) equivalent to more than 100% of its investment capital. The effective leverage ratio shown for each Fund is the amount of investment exposure created either directly through borrowings or indirectly through inverse floaters, divided by the assets invested, including those assets that were purchased with the proceeds of the leverage, or referenced by the levered instrument. A Fund may from time to time borrow on a typically transient basis in connection with its day-to-day operations, primarily in connection with the need to pay cash out to redeeming shareholders or to settle portfolio trades. Such incidental borrowings, described generally in Notes to Financial Statements, Note 9 - Borrowing Arrangements, are excluded from the calculation of a Fund’s effective leverage ratio.

Yields as of March 31, 2021

Dividend Yield is the most recent dividend per share (annualized) divided by the offering price per share.

The SEC 30-Day Yield is a standardized measure of a fund’s yield that accounts for the future amortization of premiums or discounts of bonds held in the fund’s portfolio. The SEC 30-Day Yield is computed under an SEC standardized formula and is based on the maximum offer price per share. Dividend Yield may differ from the SEC 30-Day Yield because the fund may be paying out more or less than it is earning and it may not include the effect of amortization of bond premium.

The Taxable-Equivalent Yield represents the yield that must be earned on a fully taxable investment in order to equal the yield of the fund on an after-tax basis at an assumed tax rate. Your actual combined federal and state income tax rates may differ from the assumed rate. Taxable-Equivalent Yield also takes into account the percentage of the Fund’s income generated and paid by the fund (based on payments made during the previous calendar year) that was either exempt from federal income tax but not from state income tax (e.g., income from an out-of state municipal bond), or was exempt from neither federal nor state income tax. Separately, if the comparison were instead to investments that generate qualified dividend income, which is taxable at a rate lower than an individual’s ordinary graduated tax rate, the fund’s Taxable-Equivalent Yield would be lower.

Expense Examples

As a shareholder of one or more of the Funds, you incur two types of costs: (1) transaction costs, including up-front and back-end sales charges (loads) or redemption fees, where applicable; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees, where applicable; and other Fund expenses. The Examples below are intended to help you understand your ongoing costs (in dollars) of investing in the Funds and to compare these costs with the ongoing costs of investing in other mutual funds. The Examples below do not include the interest and related expenses from inverse floaters that are reflected in the financial statements later within this report, when applicable.

The Examples below are based on an investment of $1,000 invested at the beginning of the period and held through the period ended March 31, 2021.

The beginning of the period is October 1, 2020.

The information under “Actual Performance,” together with the amount you invested, allows you to estimate actual expenses incurred over the reporting period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.60) and multiply the result by the cost shown for your share class, in the row entitled “Expenses Incurred During Period” to estimate the expenses incurred on your account during this period.

The information under “Hypothetical Performance,” provides information about hypothetical account values and hypothetical expenses based on each Fund’s actual expense ratios and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expense you incurred for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the following tables are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the hypothetical information is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds or share classes. In addition, if these transaction costs were included, your costs would have been higher.

(hereafter collectively referred to as the "Funds") as of March 31, 2021, the related statements of operations for the year ended March 31, 2021, the statements of changes in net assets for each of the two years in the period ended March 31, 2021, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of March 31, 2021, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period ended March 31, 2021 and each of the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinions

These financial statements are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of March 31, 2021 by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

Portfolio of Investments March 31, 2021

(1)	All percentages shown in the Portfolio of Investments are based on net assets.
(2)	Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. Optional Call Provisions are not covered by the report of independent registered public accounting firm.
(3)	For financial reporting purposes, the ratings disclosed are the highest of Standard & Poor’s Group (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”) rating. This treatment of split-rated securities may differ from that used for other purposes, such as for Fund investment policies. Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated by any of these national rating agencies. Ratings are not covered by the report of independent registered public accounting firm.
(4)	Variable rate security. The rate shown is the coupon as of the end of the reporting period.
(5)	Investment, or portion of investment, has been pledged to collateralize the net payment obligations for investments in inverse floating rate transactions.
(6)	Defaulted security. A security whose issuer has failed to fully pay principal and/or interest when due, or is under the protection of bankruptcy.

1. General Information

Trust and Fund Information

Nuveen Municipal Trust and Nuveen Investment Funds, Inc. (each a “Trust” and collectively, the “Trusts”), are open-end management investment companies registered under the Investment Company Act of 1940, (the "1940 Act"), as amended. Nuveen Municipal Trust is comprised of Nuveen All-American Municipal Bond Fund (“All-American”), Nuveen Intermediate Duration Municipal Bond Fund (“Intermediate Duration”) and Nuveen Limited Term Municipal Bond Fund (“Limited Term”), among others, and Nuveen Investment Funds, Inc. is comprised of Nuveen Short Term Municipal Bond Fund (“Short Term”), among others, (each a “Fund” and collectively, the “Funds”), as diversified funds. Nuveen Municipal Trust was organized as a Massachusetts business trust on July 1, 1996. Nuveen Investment Funds, Inc. was incorporated in the State of Maryland on August 20, 1987. The Funds, were each organized as a series of predecessor trusts or corporations prior to that date.

The end of the reporting period for the Funds is March 31, 2021, and the period covered by these Notes to Financial Statements is the fiscal year ended March 31, 2021 (the "current fiscal period”).

Investment Adviser and Sub-Adviser

The Funds’ investment adviser is Nuveen Fund Advisors, LLC (the “Adviser”), a subsidiary of Nuveen, LLC (“Nuveen”). Nuveen is the investment management arm of Teachers Insurance and Annuity Association of America (TIAA). The Adviser has overall responsibility for management of the Funds, oversees the management of the Funds’ portfolios, manages the Funds’ business affairs and provides certain clerical, bookkeeping and other administrative services, and, if necessary, asset allocation decisions. The Adviser has entered into sub-advisory agreements with Nuveen Asset Management, LLC (the “Sub-Adviser”), a subsidiary of the Adviser, under which the Sub-Adviser manages the investment portfolios of the Funds.

Fund Reorganization

During May 2020, the Funds’ Board of Directors/Trustees (the “Board”) approved the merger of Nuveen Tennessee Municipal Bond Fund (the “Target Fund”) into All-American (the “Acquiring Fund”) (the “Reorganization”). During September 28, 2020, shareholders of the Target Fund approved the Reorganization. The Reorganization was effective after the close of business on January 8, 2021.

Upon the closing of the Reorganization, the Target Fund transferred its assets to the Acquiring Fund in exchange for shares of the Acquiring Fund and the assumption by the Acquiring Fund of the liabilities of the Target Fund. The Target Fund was then liquidated, dissolved and terminated in accordance with its Declaration of Trust. Shareholders of the Target Fund became shareholders of the Acquiring Fund. Each Target Fund shareholder received shares of the Acquiring Fund, the aggregate net asset value (“NAV”) of which is equal to the aggregate NAV of the shares of the Target Fund held immediately prior to the Reorganization (including for this purpose fractional Acquiring Fund shares to which shareholders would be entitled).

For accounting and performance reporting purposes, the Acquiring Fund is the survivor. Details of the Reorganization are further described in Note 10 – Fund Reorganization.

Share Classes and Sales Charges

Class A Shares are generally sold with an up-front sales charge. Class A Share purchases of $250,000 or more are sold at NAV without an up-front sales charge but may be subject to a contingent deferred sales charge (“CDSC”) of 1% (0.70% for Limited Term and Short Term) if redeemed within eighteen months (twelve months for shares of Short Term) of purchase. Class C Shares are sold without an up-front sales charge. The Funds will issue Class C2 Shares upon the exchange of Class C2 Shares from another Nuveen mutual fund or for the purposes of dividend reinvestment, but Class C2 Shares are not available for new accounts or for additional investment into existing accounts. Class C and C2 Shares are subject to a CDSC of 1% if redeemed within twelve months of purchase. Class C and Class C2 Shares automatically convert to Class A Shares eight years (ten years prior to March 1, 2021) after purchase. Class R6 Shares and Class I Shares are sold without an up-front sale charge.

Other Matters

The outbreak of the novel coronavirus (“COVID-19”) and subsequent global pandemic began significantly impacting the U.S. and global financial markets and economies during the calendar quarter ended March 31, 2020. The worldwide spread of COVID-19 has created significant uncertainty in the global economy. The duration and extent of COVID-19 over the long term cannot be reasonably estimated at this time. The ultimate impact of COVID-19 and the extent to which COVID-19 impacts the Funds' normal course of business, results of operations, investments, and cash flows will depend on future developments, which are highly uncertain and difficult to predict. Management continues to monitor and evaluate this situation.

2. Significant Accounting Policies

The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require the use of estimates made by management and the evaluation of subsequent events. Actual results may differ from those estimates. Each Fund is an investment company and follows accounting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 946, Financial Services — Investment Companies. The NAV for financial reporting purposes may differ from the NAV for processing security and shareholder transactions. The NAV for financial reporting purposes includes security and shareholder transactions through the date of the report. Total return is computed based on the NAV used for processing security and shareholder transactions. The following is a summary of the significant accounting policies consistently followed by the Funds.

Compensation

Neither Trust pays compensation directly to those of its directors/trustees who are affiliated with the Adviser or to its officers, all of whom receive remuneration for their services to the each Trust from the Adviser or its affiliates. The Board has adopted a deferred compensation plan for independent directors/trustees that enables directors/trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen-advised funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen-advised funds.

Distributions to Shareholders

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

Indemnifications

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

Investments and Investment Income

Securities transactions are accounted for as of the trade date for financial reporting purposes. Realized gains and losses on securities transactions are based upon the specific identification method. Investment income is comprised of dividend income, which is recorded on the ex-dividend date. Non-cash dividends received in the form of stock, if any, are recognized on the ex-dividend date and recorded at fair value. Investment Income, is also comprised of interest income, which is recorded on an accrual basis and includes accretion of discounts and the amortization of premium for financial reporting purposes. Investment Income also reflects payment-in-kind (“PIK”) interest and paydown gains and losses, if any. PIK interest represents income received in the form of securities in lieu of cash.

Multiclass Operations and Allocations

Income and expenses of the Funds that are not directly attributable to a specific class of shares are prorated among the classes based on the relative value of the settled shares of each class. Expenses directly attributable to a class of shares are recorded to the specific class. 12b-1 distribution and service fees are allocated on a class-specific basis.

Sub-transfer agent fees, which are recognized as a component of “Shareholder servicing agent fees” on the Statement of Operations, are not charged to Class R6 Shares and are prorated among the other classes based on their relative settled shares.

Realized and unrealized capital gains and losses of the Funds are prorated among the classes based on the relative net assets of each class.

Netting Agreements

In the ordinary course of business, the Funds may enter into transactions subject to enforceable International Swaps and Derivative Association, Inc. (ISDA) master agreements or other similar arrangements (“netting agreements”). Generally, the right to offset in netting agreements allows each Fund to offset certain securities and derivatives with a specific counterparty, when applicable, as well as any collateral received or delivered to that counterparty based on the terms of the agreements. Generally, each Fund manages its cash collateral and securities collateral on a counterparty basis.

The Funds' investments subject to netting agreements as of the end of the reporting period, if any, are further described in Note 4 - Portfolio Securities and Investments in Derivatives.

nancial Conduct Authority (FCA). The new guidance allows companies to, provided the only change to existing contracts are a change to an approved benchmark interest rate, account for modifications as a continuance of the existing contract without additional analysis. For new and existing contracts, the Funds may elect to apply the amendments as of March 12, 2020 through December 31, 2022. Management has not yet elected to apply the amendments, is continuously evaluating the potential effect a discontinuation of LIBOR could have on the Funds’ investments and has currently determined that it is unlikely the ASU’s adoption will have a significant impact on the Funds’ financial statements and various filings.

Securities and Exchange Commission (“SEC”) Adopts New Rules to Modernize Fund Valuation Framework

In December 2020, the SEC voted to adopt a new rule governing fund valuation practices. New Rule 2a-5 under the 1940 Act establishes requirements for determining fair value in good faith for purposes of the 1940 Act. Rule 2a-5 will permit fund boards to designate certain parties to perform fair value determinations, subject to board oversight and certain other conditions. Rule 2a-5 also defines when market quotations are “readily available” for purposes of Section 2(a)(41) of the 1940 Act, which requires a fund to fair value a security when market quotation are not readily available. The SEC also adopted new Rule 31a-4 under the 1940 Act, which sets forth the recordkeeping requirements associated with fair value determinations. Finally, the SEC is rescinding previously issued guidance on related issues, including the role of a board in determining fair value and the accounting and auditing of fund investments. Rule 2a-5 and Rule 31a-4 became effective on March 8, 2021, with a compliance date of September 8, 2022. A fund may voluntarily comply with the rules after the effective date, and in advance of the compliance date, under certain conditions. Management is currently assessing the impact of these provisions on the Funds' financial statements.

3. Investment Valuation and Fair Value Measurements

The Funds' investments in securities are recorded at their estimated fair value utilizing valuation methods approved by the Board. Fair value is defined as the price that would be received 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. U.S. GAAP establishes the three-tier hierarchy which 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 management’s 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.

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, credit spreads, etc.).

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

A description of the valuation techniques applied to the Funds’ major classifications of assets and liabilities measured at fair value follows:

Equity securities and exchange-traded funds listed or traded on a national market or exchange are valued based on their sale price at the official close of business of such market or exchange on the valuation date. Foreign equity securities and registered investment companies that trade on a foreign exchange are valued at the last sale price or official closing price reported on the exchange where traded and converted to U.S. dollars at the prevailing rates of exchange on the date of valuation. To the extent these securities are actively traded and that valuation adjustments are not applied, they are generally classified as Level 1. If there is no official close of business, then the latest available sale price is utilized. If no sales are reported, then the mean of the latest available bid and ask prices is utilized and these securities are generally classified as Level 2.

Prices of fixed-income securities are generally provided by an independent pricing service (“pricing service”) approved by the Board. 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.

Futures contracts are valued using the closing settlement price or, in the absence of such a price, the last traded price and are generally classified as Level 1.

Any portfolio security or derivative for which market quotations are not readily available or for which the above valuation procedures are deemed not to reflect fair value are valued at fair value, as determined in good faith using procedures approved by the Board. 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. To the extent the inputs are observable and timely, the values would be classified as Level 2 of the fair value hierarchy; otherwise they would be classified as Level 3.

The Funds hold liabilities in floating rate obligations and preferred shares, where applicable, which are not reflected in the tables above. The fair values of the Funds' liabilities for floating rate obligations approximate their liquidation values. Floating rate obligations are generally classified as Level 2 and further described in Note 4 - Portfolio Securities and Investments in Derivatives. The fair values of the Funds' liabilities for preferred shares approximate their liquidation preference. Preferred shares are generally classified as Level 2 and further described in Note 5 - Fund Shares.

4. Portfolio Securities and Investments in Derivatives

Portfolio Securities

Inverse Floating Rate Securities

Each Fund is authorized to invest in inverse floating rate securities. An inverse floating rate security is created by depositing a municipal bond (referred to as an “Underlying Bond”), typically with a fixed interest rate, into a special purpose tender option bond (“TOB”) trust (referred to as the “TOB Trust”) created by or at the direction of one or more Funds. In turn, the TOB Trust issues (a) floating rate certificates (referred to as “Floaters”), in face amounts equal to some fraction of the Underlying Bond’s par amount or market value, and (b) an inverse floating rate certificate (referred to as an “Inverse Floater”) that represents all remaining or residual interest in the TOB Trust. Floaters typically pay short-term tax-exempt interest rates to third parties who are also provided a right to tender their certificate and receive its par value, which may be paid from the proceeds of a remarketing of the Floaters, by a loan to the TOB Trust from a third party liquidity provider (“Liquidity Provider”), or by the sale of assets from the TOB Trust. The Inverse Floater is issued to a long term investor, such as one or more Funds. The income received by the Inverse Floater holder varies inversely with the short-term rate paid to holders of the Floaters, and in most circumstances the Inverse Floater holder bears substantially all of the Underlying Bond’s down-

295

Notes to Financial Statements (continued)

side investment risk and also benefits disproportionately from any potential appreciation of the Underlying Bond’s value. The value of an Inverse Floater will be more volatile than that of the Underlying Bond because the interest rate is dependent on not only the fixed coupon rate of the Underlying Bond but also on the short-term interest paid on the Floaters, and because the Inverse Floater essentially bears the risk of loss (and possible gain) of the greater face value of the Underlying Bond.

The Inverse Floater held by a Fund gives the Fund the right to (a) cause the holders of the Floaters to tender their certificates at par (or slightly more than par in certain circumstances), and (b) have the trustee of the TOB Trust (the “Trustee”) transfer the Underlying Bond held by the TOB Trust to the Fund, thereby collapsing the TOB Trust.

The Fund may acquire an Inverse Floater in a transaction where it (a) transfers an Underlying Bond that it owns to a TOB Trust created by a third party or (b) transfers an Underlying Bond that it owns, or that it has purchased in a secondary market transaction for the purpose of creating an Inverse Floater, to a TOB Trust created at its direction, and in return receives the Inverse Floater of the TOB Trust (referred to as a “self-deposited Inverse Floater”). A Fund may also purchase an Inverse Floater in a secondary market transaction from a third party creator of the TOB Trust without first owning the Underlying Bond (referred to as an “externally-deposited Inverse Floater”).

An investment in a self-deposited Inverse Floater is accounted for as a “financing” transaction (i.e., a secured borrowing). For a self-deposited Inverse Floater, the Underlying Bond deposited into the TOB Trust is identified in the Fund’s Portfolio of Investments as “(UB) – Underlying bond of an inverse floating rate trust reflected as a financing transaction,” with the Fund recognizing as liabilities, labeled “Floating rate obligations” on the Statement of Assets and Liabilities, (a) the liquidation value of Floaters issued by the TOB Trust, and (b) the amount of any borrowings by the TOB Trust from a Liquidity Provider to enable the TOB Trust to purchase outstanding Floaters in lieu of a remarketing. In addition, the Fund recognizes in “Investment Income” the entire earnings of the Underlying Bond, and recognizes (a) the interest paid to the holders of the Floaters or on the TOB Trust’s borrowings, and (b) other expenses related to remarketing, administration, trustee, liquidity and other services to a TOB Trust, as a component of “Interest expense” on the Statement of Operations. Earnings due from the Underlying Bond and interest due to the holders of the Floaters as of the end of the reporting period are recognized as components of “Receivable for interest” and “Payable for interest” on the Statement of Assets and Liabilities, respectively.

In contrast, an investment in an externally-deposited Inverse Floater is accounted for as a purchase of the Inverse Floater and is identified in the Fund’s Portfolio of Investments as “(IF) – Inverse floating rate investment.” For an externally-deposited Inverse Floater, a Fund’s Statement of Assets and Liabilities recognizes the Inverse Floater and not the Underlying Bond as an asset, and the Fund does not recognize the Floaters, or any related borrowings from a Liquidity Provider, as a liability. Additionally, the Fund reflects in “Investment Income” only the net amount of earnings on the Inverse Floater (net of the interest paid to the holders of the Floaters or the Liquidity Provider as lender, and the expenses of the Trust), and does not show the amount of that interest paid or the expenses of the TOB Trust as described above as interest expense on the Statement of Operations.

Fees paid upon the creation of a TOB Trust for self-deposited Inverse Floaters and externally-deposited Inverse Floaters are recognized as part of the cost basis of the Inverse Floater and are capitalized over the term of the TOB Trust.

As of the end of the reporting period, the aggregate value of Floaters issued by each Fund’s TOB Trust for self-deposited Inverse Floaters and externally-deposited Inverse Floaters was as follows:

Floating Rate Obligations Outstanding	All-American	Intermediate Duration	Limited Term	Short Term
Floating rate obligations: self-deposited Inverse Floaters	$422,375,000	$ —	$ —	$ —
Floating rate obligations: externally-deposited Inverse Floaters	7,500,000	12,490,000	—	—
Total	$429,875,000	$12,490,000	$ —	$ —

During the current fiscal period, the average amount of Floaters (including any borrowings from a Liquidity Provider) outstanding, and the average annual interest rates and fees related to self-deposited Inverse Floaters, were as follows:

Self-Deposited Inverse Floaters	All-American	Intermediate Duration	Limited Term	Short Term
Average floating rate obligations outstanding	$239,542,151	$ —	$ —	$ —
Average annual interest rate and fees	0.70%	—%	—%	—%

TOB Trusts are supported by a liquidity facility provided by a Liquidity Provider pursuant to which the Liquidity Provider agrees, in the event that Floaters are (a) tendered to the Trustee for remarketing and the remarketing does not occur, or (b) subject to mandatory tender pursuant to the terms of the TOB Trust agreement, to either purchase Floaters or to provide the Trustee with an advance from a loan facility to fund the purchase of Floaters by the TOB Trust. In certain circumstances, the Liquidity Provider may otherwise elect to have the Trustee sell the Underlying Bond to retire the Floaters that were tendered and not remarketed prior to providing such a loan. In these circumstances, the Liquidity Provider remains obligated to provide a loan to the extent that the proceeds of the sale of the Underlying Bond are not sufficient to pay the purchase price of the Floaters.

296

Table of Contents

The size of the commitment under the loan facility for a given TOB Trust is at least equal to the balance of that TOB Trust’s outstanding Floaters plus any accrued interest. In consideration of the loan facility, fee schedules are in place and are charged by the Liquidity Provider(s). Any loans made by the Liquidity Provider will be secured by the purchased Floaters held by the TOB Trust. Interest paid on any outstanding loan balances will be effectively borne by the Fund that owns the Inverse Floaters of the TOB Trust that has incurred the borrowing and may be at a rate that is greater than the rate that would have been paid had the Floaters been successfully remarketed.

As described above, any amounts outstanding under a liquidity facility are recognized as a component of “Floating rate obligations” on the Statement of Assets and Liabilities by the Fund holding the corresponding Inverse Floaters issued by the borrowing TOB Trust. As of the end of the reporting period, there were no loans outstanding under any such facility.

Each Fund may also enter into shortfall and forbearance agreements (sometimes referred to as a “recourse arrangement”) (TOB Trusts involving such agreements are referred to herein as “Recourse Trusts”), under which a Fund agrees to reimburse the Liquidity Provider for the Trust’s Floaters, in certain circumstances, for the amount (if any) by which the liquidation value of the Underlying Bond held by the TOB Trust may fall short of the sum of the liquidation value of the Floaters issued by the TOB Trust plus any amounts borrowed by the TOB Trust from the Liquidity Provider, plus any shortfalls in interest cash flows. Under these agreements, a Fund’s potential exposure to losses related to or on an Inverse Floater may increase beyond the value of the Inverse Floater as a Fund may potentially be liable to fulfill all amounts owed to holders of the Floaters or the Liquidity Provider. Any such shortfall amount in the aggregate is recognized as “Unrealized depreciation on Recourse Trusts” on the Statement of Assets and Liabilities.

As of the end of the reporting period, the Funds maximum exposure to the Floaters issued by Recourse Trusts for self-deposited Inverse Floaters and externally-deposited Inverse Floaters was as follows:

Floating Rate Obligations - Recourse Trusts	All-American	Intermediate Duration	Limited Term	Short Term
Maximum exposure to Recourse Trusts: self-deposited Inverse Floaters	$422,375,000	$ —	$ —	$ —
Maximum exposure to Recourse Trusts: externally-deposited Inverse Floaters	7,500,000	12,490,000	—	—
Total	$429,875,000	$12,490,000	$ —	$ —

Zero Coupon Securities

A zero coupon security does not pay a regular interest coupon to its holders during the life of the security. Income to the holder of the security comes from accretion of the difference between the original purchase price of the security at issuance and the par value of the security at maturity and is effectively paid at maturity. The market prices of zero coupon securities generally are more volatile than the market prices of securities that pay interest periodically.

Investment Transactions

Long-term purchases and sales (including maturities but excluding derivative transactions, where applicable) during the current fiscal period, were as follows:

	All-American	Intermediate Duration	Limited Term	Short Term
Purchases	$3,303,289,263	$2,704,438,667	$2,914,538,302	$351,263,067
Sales and maturities	1,322,121,957	1,661,283,923	1,234,646,825	277,556,593

The Funds may purchase securities on a when-issued or delayed-delivery basis. Securities purchased on a when-issued or delayed-delivery basis may have extended settlement periods; interest income is not accrued until settlement date. Any securities so purchased are subject to market fluctuation during this period. The Funds have earmarked securities in their portfolios with a current value at least equal to the amount of the when-issued/delayed delivery purchase commitments. If a Fund has outstanding when-issued/delayed-delivery purchases commitments as of the end of the reporting period, such amounts are recognized on the Statement of Assets and Liabilities.

Investments in Derivatives

In addition to the inverse floating rate securities in which each Fund may invest, which are considered portfolio securities for financial reporting purposes, each Fund is authorized to invest in certain other derivative instruments. The Funds record derivative instruments at fair value, with changes in fair value recognized on the Statement of Operations, when applicable. Even though the Funds’ investments in derivatives may represent economic hedges, they are not considered to be hedge transactions for financial reporting purposes.

Futures Contracts

market” of the open contracts. If a Fund has unrealized appreciation the clearing broker would credit the Fund’s account with an amount equal to appreciation and conversely if a Fund has unrealized depreciation the clearing broker would debit the Fund’s account with an amount equal to depreciation. These daily cash settlements are also known as “variation margin.” Variation margin is recognized as a receivable and/or payable for “Variation margin on futures contracts” on the Statement of Assets and Liabilities.

During the period the futures contract is open, changes in the value of the contract are recognized as an unrealized gain or loss by “marking-to-market” on a daily basis to reflect the changes in market value of the contract, which is recognized as a component of “Change in net unrealized appreciation (depreciation) of futures contracts” on the Statement of Operations. When the contract is closed or expired, a Fund records a realized gain or loss equal to the difference between the value of the contract on the closing date and value of the contract when originally entered into, which is recognized as a component of “Net realized gain (loss) from futures contracts” on the Statement of Operations.

Risks of investments in futures contracts include the possible adverse movement in the price of the securities or indices underlying the contracts, the possibility that there may not be a liquid secondary market for the contracts and/or that a change in the value of the contract may not correlate with a change in the value of the underlying securities or indices.

During the current fiscal period, All-American managed the duration of its portfolio by shorting interest rate futures contracts.

The average notional amount of futures contracts outstanding during the current fiscal period was as follows:

	All-American
Average notional amount of futures contracts outstanding*	$17,821,038

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

The following table presents the amount of net realized gain (loss) and change in net unrealized appreciation (depreciation) recognized on futures contracts on the Statement of Operations during the current fiscal period, and the primary underlying risk exposure.

Fund	Underlying Risk Exposure	Derivative Instrument	Net Realized Gain (Loss) from Futures Contracts	Change in Net Unrealized Appreciation (Depreciation) of Futures Contracts
All-American	Interest rate	Futures contracts	$(1,335,976)	$1,353,022

Market and Counterparty Credit Risk

In the normal course of business each 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 each Fund to counterparty credit risk, consist principally of cash due from counterparties on forward, option and swap transactions, when applicable. The extent of each Fund’s exposure to counterparty credit risk in respect to these financial assets approximates their carrying value as recorded on the Statement of Assets and Liabilities.

Each 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 each Fund with a value approximately equal to the amount of any unrealized gain above a pre-determined threshold. Reciprocally, when each Fund has an unrealized loss, the Funds have instructed the custodian to pledge assets of the Funds 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.

6. Income Tax Information

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all of its net investment income and net capital gains to shareholders and to otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. Therefore, no federal income tax provision is required. Furthermore, each Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from regular federal income taxes, to retain such tax-exempt status when distributed to shareholders of the Funds. Net realized capital gains and ordinary income distributions paid by the Funds are subject to federal taxation.

For all open tax years and all major taxing jurisdictions, management of the Funds 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 Funds 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.

Table of Contents

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 taxable market discount, timing differences in recognizing certain gains and losses on investment transactions and the treatment of investments in inverse floating rate securities reflected as financing transactions, if any. 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 NAVs of the Funds.

The table below presents the cost and unrealized appreciation (depreciation) of each Fund's investment portfolio, as determined on a federal income tax basis, as of March 31, 2021.

For purposes of this disclosure, derivative tax cost is generally the sum of any upfront fees or premiums exchanged and any amounts unrealized for income statement reporting but realized in income and/or capital gains for tax reporting. If a particular derivative category does not disclose any tax unrealized appreciation or depreciation, the change in value of those derivatives have generally been fully realized for tax purposes.

	All-American	Intermediate Duration	Limited Term	Short Term
Tax cost of investments	$7,238,715,169	$9,737,883,009	$7,572,557,211	$785,453,236
Gross unrealized:
Appreciation	$ 564,027,568	$ 528,952,389	$ 248,058,571	$ 13,844,466
Depreciation	(27,899,157)	(29,318,415)	(10,830,479)	(708,237)
Net unrealized appreciation (depreciation) of investments	$ 536,128,411	$ 499,633,974	$ 237,228,092	$ 13,136,229

Permanent differences, primarily due to taxable market discount, distressed PIK bond adjustments, reorganization adjustments, investments in partnerships and paydowns, resulted in reclassifications among the Funds’ components of net assets as of March 31, 2021, the Funds' tax year end.

The tax components of undistributed net tax-exempt income, net ordinary income and net long-term capital gains as of March 31, 2021, the Funds’ tax year end, were as follows:

	All-American	Intermediate Duration	Limited Term	Short Term
Undistributed net tax-exempt income¹	$4,286,656	$6,131,535	$ —	$727,271
Undistributed net ordinary income²	8,724	361,014	—	4,265
Undistributed net long-term capital gains	—	—	—	—

¹	Undistributed net tax-exempt income (on a tax basis) has not been reduced for the dividends declared during the period March 1, 2021 through March 31, 2021, and paid on April 1, 2021.
²	Net ordinary income consists of taxable market discount income and net short-term capital gains, if any.

The tax character of distributions paid during the Funds' tax years ended March 31, 2021 and March 31, 2020 was designated for purposes of the dividends paid deduction as follows:

2021	All-American	Intermediate Duration	Limited Term	Short Term

7. Management Fees and Other Transactions with Affiliates

Management Fees

Each Fund’s management fee compensates the Adviser for the overall investment advisory and administrative services and general office facilities. The Sub-Adviser is compensated for its services to the Funds from the management fees paid to the Adviser.

Each Fund’s management fee consists of two components – a fund-level fee, based only on the amount of assets within each individual Fund, and a complex-level fee, based on the aggregate amount of all eligible fund assets managed by the Adviser. This pricing structure enables each Fund’s shareholders to benefit from growth in the assets within their respective Fund as well as from growth in the amount of complex-wide assets managed by the Adviser.

The annual fund-level fee, payable monthly, for each Fund is calculated according to the following schedule:

Average Daily Net Assets	All- American	Intermediate Duration	Limited Term	Short Term
For the first $125 million	0.3000%	0.3000%	0.2500%	0.2500%
For the next $125 million	0.2875	0.2875	0.2375	0.2375
For the next $250 million	0.2750	0.2750	0.2250	0.2250
For the next $500 million	0.2625	0.2625	0.2125	0.2125
For the next $1 billion	0.2500	0.2500	0.2000	0.2000
For the next $3 billion	0.2250	0.2250	0.1750	0.1750
For the next $5 billion	0.2000	0.2000	0.1500	0.1500
For net assets of $10 billion and greater	0.1875	0.1875	0.1375	0.1375

The annual complex-level fee, payable monthly, for each Fund is determined by taking the complex-level fee rate, which is based on the aggregate amount of “eligible assets” of all Nuveen funds as set forth in the schedule below, and for All-American, Intermediate Duration and Short Term, making, as appropriate, an upward adjustment to that rate based upon the percentage of the fund’s assets that are not “eligible assets.” The complex level fee schedule for each Fund is as follows:

Complex-Level Eligible Asset Breakpoint Level*	Effective Complex-Level Fee Rate at Breakpoint Level
$55 billion	0.2000%
$56 billion	0.1996
$57 billion	0.1989
$60 billion	0.1961
$63 billion	0.1931
$66 billion	0.1900
$71 billion	0.1851
$76 billion	0.1806
$80 billion	0.1773
$91 billion	0.1691
$125 billion	0.1599
$200 billion	0.1505
$250 billion	0.1469
$300 billion	0.1445

calendar year. Eligible assets include closed-end fund assets managed by the Adviser that are attributable to certain types of leverage. For these purposes, leverage includes the closed-end funds’ use of preferred stock and borrowings and certain investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities, subject to an agreement by the Adviser as to certain funds to limit the amount of such assets for determining eligible assets in certain circumstances. As of March 31, 2021, the complex-level fee for each Fund was as follows:

Fund	Complex-Level Fee
All-American	0.1578%
Intermediate Duration	0.1584%
Limited Term	0.1555%
Short Term	0.1710%

The Adviser has agreed to waive fees and/or reimburse expenses (“Expense Cap”) of the following Fund so that total annual Fund operating expenses (excluding 12b-1 distribution and/or service fees, interest expenses, taxes, acquired fund fees and expenses, fees incurred in acquiring and disposing of portfolio securities and extraordinary expenses) do not exceed the average daily net assets of any class of Fund shares in the amounts and for the time periods stated in the following table. The expense limitation may be terminated or modified only with the approval of shareholders of the Fund.

Distribution and Service Fees

Each Fund has adopted a distribution and service plan under rule 12b-1 under the 1940 Act. Class A Shares incur a 0.20% annual 12b-1 service fee. Class C Shares incur a 0.75% annual 12b-1 distribution fee and a 0.25% annual 12b-1 service fee. Class C2 Shares incur a 0.55% (0.35% for Limited Term and Short Term) annual 12b-1 distribution fee and a 0.20% annual 12b-1 service fee. Class R6 Shares and Class I Shares are not subject to 12b-1 distribution or service fees. The fees under this plan compensate Nuveen Securities, LLC, (the “Distributor”), a wholly-owned subsidiary of Nuveen, for services provided and expenses incurred in distributing shares of the Funds and establishing and maintaining shareholder accounts.

Other Transactions with Affiliates

Each Fund is permitted to purchase or sell securities from or to certain other funds or accounts managed by the Sub-Adviser (“Affiliated Entity”) under specified conditions outlined in procedures adopted by the Board ("cross-trade"). These procedures have been designed to ensure that any cross-trade of securities by the Fund from or to an Affiliated Entity by virtue of having a common investment adviser (or affiliated investment adviser), common officer and/or common trustee complies with Rule 17a-7 under the 1940 Act. These transactions are effected at the current market price (as provided by an independent pricing service) without incurring broker commissions.

During the current fiscal period, the Funds engaged in cross-trades pursuant to these procedures as follows:

Cross-Trades	All-American	Intermediate Duration	Limited Term	Short Term
Purchases	$83,228,660	$ 70,200,700	$116,258,844	$22,600,000
Sales	39,001,932	155,045,000	23,400,000	32,955,037
Realized gain (loss)	(390,296)	—	—	—

During the current fiscal period, the Distributor, collected sales charges on purchases of Class A Shares, the majority of which were paid out as concessions to financial intermediaries as follows:

	All-American	Intermediate Duration	Limited Term	Short Term
Sales charges collected (Unaudited)	$6,836,649	$2,220,579	$2,430,836	$635,586
Paid to financial intermediaries (Unaudited)	6,665,015	2,174,598	2,376,637	625,596

The Distributor also received 12b-1 service fees on Class A Shares, substantially all of which were paid to compensate financial intermediaries for providing services to shareholders relating to their investments.

During the current fiscal period, the Distributor compensated financial intermediaries directly with commission advances at the time of purchase as follows:

Commission advances (Unaudited)	$6,177,402	$2,135,469	$2,313,693	$598,378

To compensate for commissions advanced to financial intermediaries, all 12b-1 service and distribution fees collected on Class C and Class C2 Shares during the first year following a purchase are retained by the Distributor. During the current fiscal period, the Distributor retained such 12b-1 fees as follows:

	All-American	Intermediate Duration	Limited Term	Short Term
12b-1 fees retained (Unaudited)	$663,392	$141,767	$169,001	$36,362

The Distributor also collected and retained CDSC on share redemptions during the current fiscal period, as follows:

	All-American	Intermediate Duration	Limited Term	Short Term
CDSC retained (Unaudited)	$584,498	$235,664	$263,687	$55,145

8. Commitments and Contingencies

In the normal course of business, each Fund enters into a variety of agreements that may expose the Fund to some risk of loss. These could include recourse arrangements for certain TOB Trusts, which are described elsewhere in these Notes to Financial Statements. The risk of future loss arising from such agreements, while not quantifiable, is expected to be remote. As of the end of the reporting period, the Funds did not have any unfunded commitments.

From time to time, the Funds may be a party to certain legal proceedings in the ordinary course of business, including proceedings relating to the enforcement of the Funds’ rights under contracts. As of the end of the reporting period, the Funds are not subject to any material legal proceedings.

9. Borrowing Arrangements

Committed Line of Credit

The Funds, along with certain other funds managed by the Adviser (“Participating Funds”), have established a 364-day, $2.405 billion standby credit facility with a group of lenders, under which the Participating Funds may borrow for various purposes other than leveraging for investment purposes. Each Participating Fund is allocated a designated proportion of the facility’s capacity (and its associated costs, as described below) based upon a multi-factor assessment of the likelihood and frequency of its need to draw on the facility, the size of the Fund and its anticipated draws, and the potential importance of such draws to the operations and well-being of the Fund, relative to those of the other Funds. A Fund may effect draws on the facility in excess of its designated capacity if and to the extent that other Participating Funds have undrawn capacity. The credit facility expires in June 2021 unless extended or renewed.

The credit facility has the following terms: a 0.10% upfront fee, 0.15% per annum on unused commitment amounts and a drawn interest rate equal to the higher of (a) one-month LIBOR (London Inter-Bank Offered Rate) plus 1.25% (1.00% prior to June 24, 2020) per annum or (b) the Fed Funds rate plus 1.25% (1.00% prior to June 24, 2020) per annum on amounts borrowed. Interest expense incurred by the Participating Funds, when applicable, is recognized as a component of "Interest expense" on the Statement of Operations. Participating Funds paid administration, legal and arrangement fees, which are recognized as a component of “Interest expense” on the Statement of Operations, and along with commitment fees, have been allocated among such Participating Funds based upon the relative proportions of the facility’s aggregate capacity reserved for them and other factors deemed relevant by the Adviser and the Board of each Participating Fund.

During the current fiscal period, the following Funds utilized this facility. Each Fund's maximum outstanding balance during the utilization period was as follows:

	All- American	Intermediate Duration	Limited Term
Maximum outstanding balance	$41,500,000	$117,800,000	$21,800,000

During each Fund's utilization period(s) during the current fiscal period, the average daily balance outstanding and average annual interest rate on the Borrowings were as follows:

304

Table of Contents

	All- American	Intermediate Duration	Limited Term
Utilization period (days outstanding)	58	10	8
Average daily balance outstanding	$17,427,586	$80,120,000	$10,325,000
Average annual interest rate	1.38%	1.71%	1.89%

Borrowings outstanding as of the end of the reporting period, if any, are recognized as “Borrowings” on the Statement of Assets and Liabilities, where applicable.

10. Fund Reorganization

The Reorganization as previously described in Note 1 - General Information was structured to qualify as a tax-free merger under the Internal Revenue Code for federal income tax purposes, and the Target Fund’s shareholders recognized no gain or loss for federal income tax purposes as a result. Prior to the closing of the Reorganization, the Target Fund distributed all of its net investment income and capital gains, if any. Such a distribution may be taxable to the Target Fund’s shareholders for federal income tax purposes.

Investments

The cost, fair value and net unrealized appreciation (depreciation) of the investments of the Target Fund as of the date of the Reorganization, were as follows:

	Nuveen Tennessee Municipal Bond Fund
Cost of Investments	$360,542,138
Fair value of Investments	385,012,380
Net unrealized appreciation (depreciation) of Investments	24,470,242

For financial reporting purposes, assets received and shares issued by the Acquiring Fund was recorded at fair value; however, the cost basis of the investments received from the Target Fund was carried forward to align ongoing reporting of the Acquiring Fund’s realized and unrealized gains and losses with amounts distributable to shareholders for tax purposes.

Share Transactions

The shares outstanding, net assets and NAV per share immediately prior to and after the Reorganization were as follows:

Target Fund - Prior to the Reorganization	Shares Outstanding	Net Assets	NAV per Share
Nuveen Tennessee Municipal Bond Fund
Class A	19,642,514	$233,188,419	$11.87

Glossary of Terms Used in this Report

(Unaudited)

Average Annual Total Return: This is a commonly used method to express an investment’s performance over a particular, usually multi-year time period. It expresses the return that would have been necessary each year to equal the investment’s actual cumulative performance (including change in NAV or offer price and reinvested dividends and capital gains distributions, if any) over the time period being considered.

Duration: Duration is a measure of the expected period over which a bond’s principal and interest will be paid, and consequently is a measure of the sensitivity of a bond’s (or bond fund’s) value to changes when market interest rates change. Generally, the longer a bond or fund’s duration, the more the price of the bond or fund will change as interest rates change.

Effective Leverage (Effective Leverage Ratio): Effective leverage is investment exposure created either directly through certain borrowings or indirectly through inverse floaters, divided by the assets invested, including those assets that were purchased with the proceeds of the leverage, or referenced by the levered instrument. The calculation of the Effective Leverage Ratio reflects borrowings effected on a long-term basis for investment purposes, but excludes borrowings that may occur, on a transient basis, in connection with a Fund’s day-to-day operations primarily in connection with the need to pay cash out to redeeming shareholders or to settle portfolio trades.

Gross Domestic Product (GDP): The total market value of all final goods and services produced in a country/region in a given year, equal to total consumer, investment and government spending, plus the value of exports, minus the value of imports.

Industrial Development Revenue Bond (IDR) – A unique type of revenue bond issued by a state or local government agency on behalf of a private sector company and intended to build or acquire factories or other heavy equipment and tools.

Inverse Floating Rate Securities: Inverse floating rate securities, also known as inverse floaters or tender option bonds (TOBs), are created by depositing a municipal bond, typically with a fixed interest rate, into a special purpose trust. This trust, in turn, (a) issues floating rate certificates typically paying short-term tax-exempt interest rates to third parties in amounts equal to some fraction of the deposited bond’s par amount or market value, and (b) issues an inverse floating rate certificate (sometimes referred to as an “inverse floater”) to an investor (such as a fund) interested in gaining investment exposure to a long-term municipal bond. The income received by the holder of the inverse floater varies inversely with the short-term rate paid to the floating rate certificates’ holders, and in most circumstances the holder of the inverse floater bears substantially all of the underlying bond’s downside investment risk. The holder of the inverse floater typically also benefits disproportionately from any potential appreciation of the underlying bond’s value. Hence, an inverse floater essentially represents an investment in the underlying bond on a leveraged basis.

Leverage: Leverage is created whenever a fund has investment exposure (both reward and/or risk) equivalent to more than 100% of the investment capital.

Lipper General & Insured Municipal Debt Funds Classification Average: Represents the average annualized total return for all reporting funds in the Lipper General & Insured Municipal Debt Funds Classification. Lipper returns account for the effects of management fees and assume reinvestment of distributions, but do not reflect any applicable sales charge.

Lipper Intermediate Municipal Debt Funds Classification Average: Represents the average annualized total return for all reporting funds in the Lipper Intermediate Municipal Debt Funds Classification. Lipper returns account for the effects of management fees and assume reinvestment of distributions, but do not reflect any applicable sales charge.

Net Asset Value (NAV) Per Share: A fund’s Net Assets is equal to its total assets (securities, cash and accrued earnings) less its total liabilities. For funds with multiple classes, Net Assets are determined separately for each share class. NAV per share is equal to the fund’s (or share class’) Net Assets divided by its number of shares outstanding.

Pre-Refundings: Pre-Refundings, also known as advance refundings or refinancings, occur when an issuer sells new bonds and uses the proceeds to fund principal and interest payments of older existing bonds. This process often results in lower borrowing costs for bond issuers.

S&P Municipal Bond Intermediate Index: An unleveraged, market value-weighted index containing all bonds in the S&P Municipal Bond Index that mature between 3 and 14.999 years. Index returns assume reinvestment of distributions but do not reflect any applicable sales charges or management fees.

S&P Municipal Bond Index: An unleveraged, market value-weighted index designed to measure the performance of the tax-exempt, investment-grade U.S. municipal bond market. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.

S&P Municipal Bond Short Index: An unleveraged, market value-weighted index containing all of the bonds in the S&P Municipal Bond Index with maturities between 6 months and 3.999 years.

S&P Municipal Bond Short-Intermediate Index: An unleveraged, market value-weighted index containing all bonds in the S&P Municipal Bond Index that mature between 1 and 7.999 years. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.

Total Investment Exposure: Total investment exposure is a fund’s assets managed by the Adviser that are attributable to financial leverage. For these purposes, financial leverage includes a fund’s use of preferred stock and borrowings and investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities.

Weighted Average Maturity: The average time to maturity of debt securities held in a Fund.

Annual Investment Management Agreement Approval Process

(Unaudited)

At a meeting held on May 19-21, 2020 (the “May Meeting”), the Board of Trustees or Directors, as applicable (the “Board” and each Trustee or Director, a “Board Member”) of the Funds, which is comprised entirely of Board Members who are not “interested persons” (as defined under the Investment Company Act of 1940 (the “1940 Act”)) (the “Independent Board Members”), approved, for each Fund, the renewal of the management agreement (each, an “Investment Management Agreement”) with Nuveen Fund Advisors, LLC (the “Adviser”) pursuant to which the Adviser serves as investment adviser to such Fund and the sub-advisory agreement (each, a “Sub-Advisory Agreement”) with Nuveen Asset Management, LLC (the “Sub-Adviser”) pursuant to which the Sub-Adviser serves as the investment sub-adviser to such Fund. Although the 1940 Act requires that continuances of the Advisory Agreements (as defined below) be approved by the in-person vote of a majority of the Independent Board Members, the May Meeting was held virtually through the internet in view of the health risks associated with holding an in-person meeting during the COVID-19 pandemic and governmental restrictions on gatherings. The May Meeting was held in reliance on an order issued by the Securities and Exchange Commission on March 13, 2020, as extended on March 25, 2020, which provided registered investment companies temporary relief from the in-person voting requirements of the 1940 Act with respect to the approval of a fund's advisory agreement in response to the challenges arising in connection with the COVID-19 pandemic.

Following up to an initial two-year period, the Board considers the renewal of each Investment Management Agreement and Sub-Advisory Agreement on behalf of the applicable Fund on an annual basis. The Investment Management Agreements and Sub-Advisory Agreements are collectively referred to as the “Advisory Agreements” and the Adviser and the Sub-Adviser are collectively, the “Fund Advisers” and each, a “Fund Adviser.” Throughout the year, the Board and its committees meet regularly and, at these meetings, review an extensive array of topics and information that are relevant to its annual consideration of the renewal of the advisory agreements for the Nuveen funds. Such information may address, among other things, fund performance; the Adviser’s strategic plans; the review of the funds and investment teams; compliance, regulatory and risk management matters; the trading practices of the various sub-advisers to the funds; valuation of securities; fund expenses; payments to financial intermediaries, including 12b-1 fees and sub-transfer agency fees, if applicable; and overall market and regulatory developments.

In addition to the information and materials received during the year, the Board, in response to a request made on its behalf by independent legal counsel, received extensive materials and information prepared specifically for its annual consideration of the renewal of the advisory agreements for the Nuveen funds by the Adviser and by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent provider of investment company data. The materials cover a wide range of topics including, but not limited to, a description of the nature, extent and quality of services provided by the Fund Advisers; a review of each sub-adviser to the Nuveen funds and the applicable investment teams; an analysis of fund performance in absolute terms and as compared to the performance of certain peer funds and benchmarks with a focus on any performance outliers; an analysis of the fees and expense ratios of the Nuveen funds in absolute terms and as compared to those of certain peer funds with a focus on any expense outliers; a description of portfolio manager compensation; a review of the performance of various service providers; a description of various initiatives Nuveen had undertaken or continued during the year for the benefit of particular fund(s) and/or the complex; a description of the profitability or financial data of Nuveen and the sub-advisers to the Nuveen funds; and a description of indirect benefits received by the Adviser and the sub-advisers as a result of their relationships with the Nuveen funds.

In continuing its practice, the Board met prior to the May Meeting to begin its considerations of the renewal of the Advisory Agreements. Accordingly, on April 27-28, 2020 (the “April Meeting”), the Board met to review and discuss, in part, the performance of the Nuveen funds and the Adviser’s evaluation of each sub-adviser to the Nuveen funds. In its review, the Board recognized the volatile market conditions occurring during the first half of 2020 arising, in part, from the public health crisis caused by the novel coronavirus known as COVID-19 and the resulting impact on fund performance. Accordingly, the Board reviewed, among other things, fund performance reflecting the more volatile periods, including for various time periods ended the first quarter of 2020 and for various time periods ended April 17, 2020. At the April Meeting, the Board Members asked questions and requested additional information that was provided for the May Meeting. In continuing its review of the Nuveen funds in light of the extraordinary market conditions experienced in early 2020, the Board received updated fund performance data reflecting various time periods ended May 8, 2020 for its May Meeting. The Board also continued its practice of seeking to meet periodically with the various sub-advisers to the Nuveen funds and their investment teams, when feasible.

The Independent Board Members considered the review of the advisory agreements for the Nuveen funds to be an ongoing process and employed the accumulated information, knowledge, and experience the Board Members had gained during their tenure on the boards governing the Nuveen funds and working with the Adviser and sub-advisers in their review of the advisory agreements. The contractual arrangements are a result of multiple years of review, negotiation and information provided in connection with the boards’ annual review of the Nuveen funds’ advisory arrangements and oversight of the Nuveen funds.

Annual Investment Management Agreement Approval Process (Unaudited) (continued)

The Independent Board Members were advised by independent legal counsel during the annual review process as well as throughout the year, including meeting in executive sessions with such counsel at which no representatives from the Adviser or the Sub-Adviser were present. In connection with their annual review, the Independent Board Members also received a memorandum from independent legal counsel outlining their fiduciary duties and legal standards in reviewing the Advisory Agreements.

The Board’s decision to renew the Advisory Agreements was not based on a single identified factor, but rather the decision reflected the comprehensive consideration of all the information provided throughout the year and at the April and May Meetings, and each Board Member may have attributed different levels of importance to the various factors and information considered in connection with the approval process. The following summarizes the principal factors and information, but not all the factors, the Board considered in deciding to renew the Advisory Agreements and its conclusions.

A. Nature, Extent and Quality of Services

In evaluating the renewal of the Advisory Agreements, the Independent Board Members received and considered information regarding the nature, extent and quality of the applicable Fund Adviser’s services provided to the respective Fund with particular focus on the services and enhancements to such services provided during the last year. The Independent Board Members considered the Investment Management Agreements and the Sub-Advisory Agreements separately in the course of their review. With this approach, they considered the respective roles of the Adviser and the Sub-Adviser in providing services to the Funds.

With respect to the Adviser, the Board recognized that the Adviser has provided a vast array of services the scope of which has expanded over the years in light of regulatory, market and other developments, such as the development of a liquidity management program and expanded compliance programs for the Nuveen funds. The Board also noted the extensive resources, tools and capabilities the Adviser and its affiliates devoted to the various operations of the Nuveen funds. These services include, but are not limited to: investment oversight, risk management and securities valuation services (such as analyzing investment performance and risk data; overseeing and reviewing the various sub-advisers to the Nuveen funds and their investment teams; overseeing trade execution, soft dollar practices and securities lending activities; providing daily valuation services and developing related valuation policies, procedures and methodologies; overseeing risk disclosure; periodic testing of investment and liquidity risks; participating in financial statement and marketing disclosures; participating in product development; and participating in leverage management and liquidity monitoring); product management (such as analyzing a fund’s position in the marketplace, setting dividends, preparing shareholder and intermediary communications and other due diligence support); fund administration (such as preparing fund tax returns and other tax compliance services, overseeing the funds’ independent public accountants and other service providers; managing fund budgets and expenses; and helping to fulfill the funds’ regulatory filing requirements); oversight of shareholder services and transfer agency functions (such as overseeing transfer agent service providers which include registered shareholder customer service and transaction processing; and overseeing proxy solicitation and tabulation services); Board relations services (such as organizing and administering Board and committee meetings, preparing various reports to the Board and committees and providing other support services); compliance and regulatory oversight services (such as devising compliance programs; managing compliance policies; monitoring compliance with applicable fund policies and laws and regulations; and evaluating the compliance programs of the various sub-advisers to the Nuveen funds and certain other service providers); and legal support and oversight of outside law firms (such as helping to prepare and file registration statements and proxy statements; overseeing fund activities and providing legal interpretations regarding such activities; and negotiating agreements with other fund service providers).

The Board also recognized that the Adviser and its affiliates have undertaken a number of initiatives over the previous year that benefited the complex and/or particular Nuveen funds including, but not limited to:

•	Fund Improvements and Product Management Initiatives – continuing to proactively manage the Nuveen fund complex as a whole and at the individual fund level with an aim to enhance the shareholder outcomes through, among other things, rationalizing the product line and gaining efficiencies through mergers, repositionings and liquidations; launching new share classes; reviewing and updating investment policies and benchmarks; closing funds to new investments; rebranding the exchange-traded fund (“ETF”) product line; and integrating certain investment teams and changing the portfolio managers serving various funds;
•	Capital Initiatives – continuing to invest capital to support new Nuveen funds with initial capital as well as to facilitate modifications to the strategies or structure of existing funds;
•	Liquidity Management – implementing the liquidity risk management program which was designed to assess and manage the liquidity risk of the Nuveen funds. The Board noted that this program was particularly helpful in addressing the high volatility and liquidity challenges that arose in the market, particularly for the high yield municipal sector, during the first half of 2020;
•	Compliance Program Initiatives – continuing efforts to mitigate compliance risk, increase operating efficiencies, strengthen key compliance program elements and support international business growth and other objectives through, among other things, integrating various investment teams across affiliates, consolidating marketing review functions, enhancing compliance related technologies and establishing and maintaining shared broad-based compliance policies throughout the organization and its affiliates;

312

Table of Contents

•	Risk Management and Valuation Services – continuing efforts to provide Nuveen with a more disciplined and consistent approach to identifying and mitigating the firm’s operational risks through, among other things, enhancing the interaction and reporting between the investment risk management team and various affiliates and adopting a risk operational framework across the complex;
•	Regulatory Matters – continuing efforts to monitor regulatory trends and advocate on behalf of the Nuveen funds, to implement and comply with new or revised rules and mandates and to respond to regulatory inquiries and exams;
•	Government Relations – continuing efforts of various Nuveen teams and affiliates to develop policy positions on a broad range of issues that may impact the Nuveen funds, advocate and communicate these positions to lawmakers and other regulatory authorities and work with trade associations to ensure these positions are represented;
•	Business Continuity, Disaster Recovery and Information Services – continuing to periodically test business continuity and disaster recovery plans, maintain an information security program designed to identify and manage information security risks, and provide reports to the Board, at least annually, addressing, among other things, management’s security risk assessment, cyber risk profile, potential impact of new or revised laws and regulations, incident tracking and other relevant information technology risk-related reports; and
•	Expanded Dividend Management Services – continuing to manage the dividends among the varying types of Nuveen funds within the Nuveen complex to be consistent with the respective fund’s product design and investing resources to develop systems to assist in the process for newer products such as target term funds and ETFs.

The Board also noted the benefits to shareholders of investing in a Nuveen fund, as each Nuveen fund is a part of a large fund complex with a variety of investment disciplines, capabilities, expertise and resources available to navigate and support the funds including during stressed times as occurred in the market in the first half of 2020. In addition to the services provided by the Adviser, the Board also considered the risks borne by the Adviser and its affiliates in managing the Nuveen funds, including entrepreneurial, operational, reputational, regulatory and litigation risks.

The Board further considered the division of responsibilities between the Adviser and the Sub-Adviser and recognized that the Sub-Adviser and its investment personnel generally are responsible for the management of each Fund’s portfolio under the oversight of the Adviser and the Board. The Board considered an analysis of the Sub-Adviser provided by the Adviser which included, among other things, the Sub-Adviser’s assets under management and changes thereto, a summary of the applicable investment team and changes thereto, the investment approach of the team and the performance of the funds sub-advised by the Sub-Adviser over various periods. The Board further considered at the May Meeting or prior meetings evaluations of the Sub-Adviser’s compliance program and trade execution. The Board also considered the structure of investment personnel compensation programs and whether this structure provides appropriate incentives to act in the best interests of the respective Nuveen funds. The Board noted that the Adviser recommended the renewal of the Sub-Advisory Agreements.

Based on its review, the Board determined, in the exercise of its reasonable business judgment, that it was satisfied with the nature, extent and quality of services provided to the respective Funds under each applicable Advisory Agreement.

B. The Investment Performance of the Funds and Fund Advisers

In evaluating the quality of the services provided by the Fund Advisers, the Board also received and considered a variety of investment performance data of the Nuveen funds they advise. In this regard, the Board reviewed, among other things, Fund performance over the quarter, one-, three- and five-year periods ending December 31, 2019. The performance data was based on Class A shares; however, the performance of other classes should be substantially similar as they invest in the same portfolio of securities and differences in performance among the classes would be principally attributed to the variations in the expense structures of the classes. Unless otherwise indicated, the performance data referenced below reflects the periods ended December 31, 2019. In general, the year 2019 was a period of strong market performance. However, as noted above, the Board recognized the unprecedented market volatility and decline that occurred in early 2020 and the significant impact it would have on fund performance. As a result, the Board reviewed performance data capturing more recent time periods, including performance data reflecting the first quarter of 2020 as well as performance data for various periods ended April 17, 2020 for its April Meeting and May 8, 2020 for its May Meeting.

The Board reviewed both absolute and relative fund performance during the annual review over the various time periods. With respect to the latter, the Board considered fund performance in comparison to the performance of peer funds (the “Performance Peer Group”) and recognized and/or customized benchmarks (i.e., generally benchmarks derived from multiple recognized benchmarks). For funds that had changes in portfolio managers, the Board considered performance data of such funds before and after such changes. In considering performance data, the Board is aware of certain inherent limitations with such data, including that differences between the objective(s), strategies and other characteristics of the Nuveen funds compared to the respective Performance Peer Group and/or benchmark(s) (such as differences in the use of leverage) as well as differences in the composition of the Performance Peer Group over time will necessarily contribute to differences in performance results and limit the value of the comparative information. To assist the Board in its review of the comparability of the relative performance, the Adviser has ranked the relevancy of the peer group to the funds as low, medium or high.

Annual Investment Management Agreement Approval Process (Unaudited) (continued)

As noted above, the Board reviewed fund performance over various periods ended December 31, 2019 as well as the first quarter of 2020 and various time periods ended April 17, 2020 and May 8, 2020. In light of the significant market decline in the early part of 2020, the Board noted that a shorter period of underperformance may significantly impact longer term performance. Further, the Board recognized that performance data may differ significantly depending on the ending date selected and accordingly, performance results for periods ended at the year-end of 2019 may vary significantly from performance results for periods ended in the first quarter of 2020, particularly given the extraordinary market conditions at that time as the impact of COVID-19 and other market developments unfolded. The Board considered a fund’s performance in light of the overall financial market conditions. In addition, the Board recognized that shareholders may evaluate performance based on their own holding periods which may differ from the periods reviewed by the Board and lead to differing results.

In addition to the performance data prepared in connection with the annual review of the advisory agreements of the Nuveen funds, the Board reviewed fund performance throughout the year at its quarterly meetings representing differing time periods and took into account the discussions that occurred at these Board meetings in evaluating a fund’s overall performance. The Board also considered, among other things, the Adviser’s analysis of each Nuveen fund’s performance, with particular focus on funds that were considered performance outliers (both overperformance and underperformance), the factors contributing to the performance and any steps taken to address any performance concerns. Given the volatile market conditions of early 2020, the Board considered the Adviser’s analysis of the impact of such conditions on the Nuveen funds’ performance.

The Board evaluated performance in light of various factors, including general market conditions, issuer-specific information, asset class information, fund cash flows and other factors. Accordingly, depending on the facts and circumstances, the Board may be satisfied with a fund’s performance notwithstanding that its performance may be below its benchmark or peer group for certain periods. However, with respect to any Nuveen funds for which the Board had identified performance issues, the Board monitors such funds closely until performance improves, discusses with the Adviser the reasons for such results, considers whether any steps are necessary or appropriate to address such issues, and reviews the results of any efforts undertaken.

The Board’s determinations with respect to each Fund are summarized below.

For Nuveen All-American Municipal Bond Fund (the “All-American Fund”), the Board noted that the Fund outperformed its benchmark and ranked in the first quartile of its Performance Peer Group for the one-, three- and five-year periods ended December 31, 2019. With the market decline in the first quarter of 2020, although the Fund’s performance was below the performance of its benchmark and the Fund ranked in the third quartile of its Performance Peer Group for the one-year period ended March 31, 2020, the Fund outperformed its benchmark and ranked in the first quartile of its Performance Peer Group for the three- and five-year periods ended March 31, 2020. The Board was satisfied with the Fund’s overall performance.

For Nuveen Intermediate Duration Municipal Bond Fund (the “Intermediate Duration Fund”), the Board noted that although the Fund’s performance was below the performance of its benchmark for the one- and five-year periods ended December 31, 2019, the Fund outperformed its benchmark for the three-year period ended December 31, 2019. The Fund further ranked in the first quartile of its Performance Peer Group for the one-, three- and five-year periods ended December 31, 2019. With the market decline in the first quarter of 2020, the Fund’s performance was below the performance of its benchmark for the one-, three- and five-year periods ended March 31, 2020. The Fund, however, ranked in the third quartile of its Performance Peer Group for the one-year period ended March 31, 2020 and first quartile for the three- and five-year periods ended March 31, 2020. The Board was satisfied with the Fund’s overall performance.

For Nuveen Limited Term Municipal Bond Fund (the “Limited Term Fund”), the Board noted that although the Fund’s performance was below the performance of its benchmark for the five-year period ended December 31, 2019, the Fund outperformed its benchmark for the one- and three-year periods ended December 31, 2019. The Fund further ranked in the second quartile of its Performance Peer Group for the one-, three- and five-year periods ended December 31, 2019. With the market decline in the first quarter of 2020, although the Fund’s performance was below the performance of its benchmark for the one- and five-year periods ended March 31, 2020, the Fund outperformed its benchmark for the three-year period ended March 31, 2020. The Fund further ranked in the third quartile of its Performance Peer Group for the one-year period ended March 31, 2020, the first quartile of its Performance Peer Group for the three-year period ended March 31, 2020 and the second quartile of its Performance Peer Group for the five-year period ended March 31, 2020. The Board was satisfied with the Fund’s overall performance.

For Nuveen Short Term Municipal Bond Fund (the “Short Term Fund”), the Board noted that although the Fund’s performance was below the performance of its benchmark for the three- and five-year periods ended December 31, 2019, the Fund outperformed its benchmark for the one-year period ended December 31, 2019. The Fund further ranked in the second quartile of its Performance Peer Group for the one- and three-year periods ended December 31, 2019 and first quartile for the five-year period ended December 31, 2019. With the market decline in the first quarter of 2020, the Fund’s

performance was below the performance of its benchmark for the one-, three- and five-year periods ended March 31, 2020. The Fund, however, ranked in the third quartile of its Performance Peer Group for the one- and three-year periods ended March 31, 2020 and the second quartile of its Performance Peer Group for the five-year period ended March 31, 2020. The Board was satisfied with the Fund’s overall performance.

C. Fees, Expenses and Profitability

1. Fees and Expenses

As part of its annual review, the Board considered the contractual management fee and net management fee (the management fee after taking into consideration fee waivers and/or expense reimbursements, if any) paid by a Nuveen fund to the Adviser in light of the nature, extent and quality of the services provided. The Board also considered the total operating expense ratio of each Nuveen fund before and after any fee waivers and/or expense reimbursements. More specifically, the Independent Board Members reviewed, among other things, each fund’s gross and net management fee rates (i.e., before and after expense reimbursements and/or fee waivers, if any) and net total expense ratio in relation to those of a comparable universe of funds (the “Peer Universe”) and to a more focused subset of comparable funds (the “Peer Group”) established by Broadridge. The Independent Board Members reviewed the methodology Broadridge employed to establish its Peer Universe and Peer Group and recognized that differences between the applicable fund and its respective Peer Universe and/or Peer Group as well as changes to the composition of the Peer Group and/or Peer Universe from year to year may limit some of the value of the comparative data. The Independent Board Members also considered a fund’s operating expense ratio as it more directly reflected the shareholder’s costs in investing in the respective fund.

In their review, the Independent Board Members considered, in particular, each Nuveen fund with a net expense ratio of six basis points or higher compared to that of its peer average (each, an “Expense Outlier Fund”) and an analysis as to the factors contributing to each such fund’s higher relative net expense ratio. Accordingly, in reviewing the comparative data between a fund and its peers, the Board generally considered the fund’s net expense ratio and fees to be higher if they were over 10 basis points higher, slightly higher if they were 6 to 10 basis points higher, in line if they were within approximately 5 basis points higher than the peer average and below if they were below the peer average of the Peer Group. The Independent Board Members also considered, in relevant part, a fund’s net management fee and net total expense ratio in light of its performance history.

In their review of the fee arrangements for the Nuveen funds, the Independent Board Members considered the management fee schedules, including the complex-wide and fund-level breakpoint schedules, and the expense reimbursements and/or fee waivers provided by Nuveen for each fund, as applicable. The Board noted that across the Nuveen fund complex, the complex-wide fee breakpoints reduced fees by $56.6 million and fund-level breakpoints reduced fees by $66.8 million in 2019. Further, fee caps and waivers for all applicable Nuveen funds saved approximately an additional $13.7 million in fees for shareholders in 2019.

With respect to the Sub-Adviser, the Board also considered the sub-advisory fee schedule paid to the Sub-Adviser in light of the sub-advisory services provided to the respective Fund, the breakpoint schedule and comparative data of the fees the Sub-Adviser charges to other clients, if any. In its review, the Board recognized that the compensation paid to the Sub-Adviser is the responsibility of the Adviser, not the Funds.

The Board noted that (i) the All-American Fund had a net management fee and a net expense ratio that were below the respective peer averages; (ii) the Intermediate Duration Fund and the Limited Term Fund each had a net management fee that was in line with the respective peer average and a net expense ratio that was below the respective peer average; and (iii) the Short Term Fund had a net management fee that was slightly higher than the peer average but a net expense ratio that was in line with the peer average.

Based on its review of the information provided, the Board determined that each Fund’s management fees (as applicable) to a Fund Adviser were reasonable in light of the nature, extent and quality of services provided to the Fund.

2. Comparisons with the Fees of Other Clients

In determining the appropriateness of fees, the Board also considered information regarding the fee rates the respective Fund Advisers charged to certain other types of clients and the type of services provided to these other clients. With respect to the Adviser and/or the Sub-Adviser, such other clients may include retail and institutional managed accounts, passively managed ETFs sub-advised by the Sub-Adviser but that are offered by another fund complex and municipal managed accounts offered by an unaffiliated adviser. With respect to the Sub-Adviser, the Board reviewed, among other things, the fee range and average fee of municipal retail wrap accounts and municipal institutional accounts.

the Adviser, increased investment management complexity, greater product management requirements, and higher levels of business risk or some combination of these factors. The Board further considered that the Sub-Adviser’s fee is essentially for portfolio management services and therefore more comparable to the fees it receives for retail wrap accounts and other external sub-advisory mandates. The Board concluded the varying levels of fees were justified given, among other things, the inherent differences in the products and the level of services provided to the Nuveen funds versus other clients, the differing regulatory requirements and legal liabilities and the entrepreneurial, legal and regulatory risks incurred in sponsoring and advising a registered investment company.

3. Profitability of Fund Advisers

In their review, the Independent Board Members considered information regarding Nuveen’s level of profitability for its advisory services to the Nuveen funds for the calendar years 2019 and 2018. The Board reviewed, among other things, Nuveen’s net margins (pre-tax) (both including and excluding distribution expenses); gross and net revenue margins (pre- and post-tax); revenues, expenses, and net income (pre-tax and after-tax and before distribution) of Nuveen for fund advisory services; and comparative profitability data comparing the margins of Nuveen compared to the adjusted margins of certain peers with publicly available data and with the most comparable assets under management (based on asset size and asset composition) for each of the last two calendar years. The Board also reviewed the revenues and expenses the Adviser derived from its ETF product line for the 2018 and 2019 calendar years.

In reviewing the profitability data, the Independent Board Members recognized the subjective nature of calculating profitability as the information is not audited and is dependent on cost allocation methodologies to allocate expenses of Nuveen and its affiliates between the fund and non-fund businesses. The expenses to be allocated include direct expenses in servicing the Nuveen funds as well as indirect and/or shared costs (such as overhead, legal and compliance) some of which are attributed to the Nuveen funds pursuant to the cost allocation methodologies. The Independent Board Members reviewed a description of the cost allocation methodologies employed to develop the financial information and a summary of the history of changes to the methodology over the eleven-year period from 2008 to 2019. The Board had also appointed three Independent Board Members, along with the assistance of independent counsel, to serve as the Board’s liaisons to review the development of the profitability data and any proposed changes to the cost allocation methodology prior to incorporating any such changes and to report to the full Board. The Board recognized that other reasonable and valid allocation methodologies could be employed and could lead to significantly different results. Based on the data, the Independent Board Members noted that Nuveen’s net margins were higher in 2019 than the previous year and considered the key drivers behind the revenue and expense changes that impacted Nuveen’s net margins between the years. The Board also noted the reinvestments of some of the profits into the business through, among other things, the investment of seed capital in certain funds and continued investments in enhancements to information technology, internal infrastructure and data management improvements and global investment and innovation projects.

As noted above, the Independent Board Members also considered Nuveen’s margins from its relationship to the Nuveen funds compared to the adjusted margins of certain peers with publicly available data and with the most comparable assets under management (based on asset size and asset composition) to Nuveen for the calendar years 2019 and 2018. The Independent Board Members noted that Nuveen’s margins from its relationships with the Nuveen funds were on the low range compared to the adjusted margins of the peers. The Independent Board Members, however, recognized that it is difficult to make comparisons of profitability with other investment adviser peers given that comparative data is not generally public and the calculation of profitability is subjective and affected by numerous factors (such as types of funds a peer manages, its business mix, its cost of capital, the numerous assumptions underlying the methodology used to allocate expenses and other factors) which can have a significant impact on the results.

Aside from Nuveen’s profitability, the Board recognized that the Adviser is a subsidiary of Nuveen, LLC, the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). As such, the Board also reviewed a balance sheet for TIAA reflecting its assets, liabilities and capital and contingency reserves for the 2019 and 2018 calendar years to consider the financial strength of TIAA. The Board recognized the benefit of having an investment adviser and its parent with significant resources, particularly during periods of market stress.

In addition to Nuveen, the Independent Board Members also considered the profitability of the Sub-Adviser from its relationships with the Nuveen funds. In this regard, the Independent Board Members reviewed, among other things, the Sub-Adviser’s revenues, expenses and net revenue margins (pre- and post-tax) for its advisory activities for the calendar year ended December 31, 2019 as well as its pre-tax and after-tax net revenue margins for 2019 compared to such margins for 2018. The Independent Board Members also reviewed a profitability analysis reflecting the revenues, expenses and revenue margin (pre- and post-tax) by asset type for the Sub-Adviser for the calendar year ended December 31, 2019 and the pre- and post-tax revenue margins from 2019 and 2018.

In evaluating the reasonableness of the compensation, the Independent Board Members also considered any other ancillary benefits derived by the respective Fund Adviser from its relationship with the Nuveen funds as discussed in further detail below.

Based on a consideration of all the information provided, the Board noted that Nuveen’s and the Sub-Adviser’s level of profitability was acceptable and not unreasonable in light of the services provided.

D. Economies of Scale and Whether Fee Levels Reflect These Economies of Scale

The Board considered whether there have been economies of scale with respect to the management of the Nuveen funds and whether these economies of scale have been appropriately shared with the funds. The Board recognized that although economies of scale are difficult to measure, there are several methods to help share the benefits of economies of scale, including breakpoints in the management fee schedule, fee waivers and/or expense limitations, the pricing of Nuveen funds at scale at inception and investments in Nuveen’s business which can enhance the services provided to the funds for the fees paid. The Board noted that Nuveen generally has employed these various methods. In this regard, the Board noted that the management fee of the Adviser is generally comprised of a fund-level component and a complex-level component each with its own breakpoint schedule, subject to certain exceptions. The Board reviewed the fund-level and complex-level fee schedules. The Board considered that the fund-level breakpoint schedules are designed to share economies of scale with shareholders if the particular fund grows, and the complex-level breakpoint schedule is designed to deliver the benefits of economies of scale to shareholders when the eligible assets in the complex pass certain thresholds even if the assets of a particular fund are unchanged or have declined. In the calculation of the complex-level component, the Board noted that it had approved the acquisition of several Nuveen funds by similar TIAA-CREF funds in 2019. However, to mitigate the loss of the assets of these Nuveen funds deemed eligible to be included in the calculation of the complex-wide fee when these Nuveen funds left the complex upon acquisition, Nuveen agreed to credit approximately $460 million to assets under management to the Nuveen complex in calculating the complex-wide component.

In addition to the fund-level and complex-level fee schedules, the Independent Board Members considered the temporary and/or permanent expense caps applicable to certain Nuveen funds (including the amounts of fees waived or amounts reimbursed to the respective funds in 2018 and 2019), including the permanent expense cap applicable to the Intermediate Duration Fund.

The Independent Board Members also recognized the Adviser’s continued reinvestment in its business through, among other things, investments in its business infrastructure and information technology, portfolio accounting system and other systems and platforms that will, among other things, support growth, simplify and enhance information sharing, and enhance the investment process to the benefit of all of the Nuveen funds.

Based on its review, the Board concluded that the current fee arrangements together with the Adviser’s reinvestment in its business appropriately shared any economies of scale with shareholders.

E. Indirect Benefits

The Independent Board Members received and considered information regarding other benefits the respective Fund Adviser or its affiliates may receive as a result of their relationship with the Nuveen funds. The Independent Board Members recognized that an affiliate of the Adviser serves as principal underwriter providing distribution and/or shareholder services to the open-end funds. The Independent Board Members further noted that subject to certain exceptions, the Nuveen open-end funds pay 12b-1 fees and while a majority of such fees were paid to third party broker-dealers, the Board reviewed the amount retained by the Adviser’s affiliate. In addition, the Independent Board Members also noted that various sub-advisers (including the Sub-Adviser) may engage in soft dollar transactions pursuant to which they may receive the benefit of research products and other services provided by broker-dealers executing portfolio transactions on behalf of the applicable Nuveen funds, although the Board recognized that certain sub-advisers may be phasing out the use of soft dollars over time.

The Board, however, noted that the benefits for the Sub-Adviser when transacting in fixed-income securities may be more limited as such securities generally trade on a principal basis and therefore do not generate brokerage commissions. Further, the Board considered that although the Sub-Adviser may benefit from the receipt of research and other services that it may otherwise have to pay for out of its own resources, the research may also benefit the Nuveen funds to the extent it enhances the ability of the Sub-Adviser to manage such funds or is acquired through the commissions paid on portfolio transactions of other clients.

Based on its review, the Board concluded that any indirect benefits received by a Fund Adviser as a result of its relationship with the Funds were reasonable and within acceptable parameters.

F. Other Considerations

The Board Members did not identify any single factor discussed previously as all-important or controlling. The Board Members, including the Independent Board Members, concluded that the terms of each Advisory Agreement were fair and reasonable, that the respective Fund Adviser’s fees were reasonable in light of the services provided to each Fund and that the Advisory Agreements be renewed.

Nuveen High Yield Municipal Bond Fund

Nuveen Short Duration High Yield Municipal Bond Fund

Nuveen Strategic Municipal Opportunities Fund

These Funds feature portfolio management by Nuveen Asset Management, LLC (NAM), an affiliate of Nuveen Fund Advisors, LLC, the Funds’ investment adviser. John V. Miller, CFA, has managed the Nuveen High Yield Municipal Bond Fund since 2000. John, along with Timothy T. Ryan, CFA, and Steven M. Hlavin, have managed the Nuveen Short Duration High Yield Municipal Bond Fund since its inception in 2013, while John and Tim have managed the Nuveen Strategic Municipal Opportunities Fund since its inception in 2014.

Here the portfolio management team discusses U.S. economic and market conditions, key investment strategies and the Funds’ performance for the twelve-month reporting period ended March 31, 2021.

What factors affected the U.S. economy and the national municipal bond market during the twelve-month reporting period ended March 31, 2021?

The U.S. economy rebounded more quickly than expected from the deep downturn caused by the COVID-19 crisis and containment measures, but gross domestic product (GDP) shrank 3.5% in 2020 overall compared to 2019’s annual level. After falling into a deep recession in February 2020 due to the restrictions on business and social activity to mitigate the COVID-19 spread, the economy bounced back with the help of government stimulus aiding individuals and businesses, accommodative monetary policy that kept borrowing costs low, gradual reopening of businesses and vaccine rollouts. U.S. GDP growth picked up pace in the first quarter of 2021, growing at an annualized rate of 6.4% according to the Bureau of Economic Analysis “advance” estimate, an increase from 4.3% (annualized) in the fourth quarter of 2020. 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.

The ratings disclosed are the lowest rating given by one of the following national rating agencies: Standard & Poor’s (S&P), Moody’s Investors Service, Inc. (Moody's) or Fitch, Inc (Fitch). This treatment of split-rated securities may differ from that used for other purposes, such as for Fund investment policies. Credit ratings are subject to change. AAA, AA, A, and BBB are investment grade ratings; BB, B, CCC, CC, C and D are below-investment grade ratings.

Portfolio Managers’ Comments (continued)

With the onset of the COVID-19 crisis, the Federal Reserve (Fed) enacted an array of emergency measures in March 2020 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. In August 2020, the Fed announced a change in its inflation targeting policy, moving from a program of absolute targeting to an average inflation targeting policy. Under this regime, the Fed will tolerate the inflation rate temporarily overshooting the target rate to offset periods of below-target inflation, so that inflation averages a 2% target rate over time. Fed officials remained cautious, acknowledging the economy’s significant improvement from the COVID-19 crisis recession but also expressing concerns about near-term weakness, and left monetary policy unchanged over the remainder of their meetings in 2020 and early 2021.

The municipal bond market’s positive performance over the twelve-month reporting period reflects its recovery from the pandemic sell-off in March 2020. 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. However, early in the reporting period, the market was beginning to stabilize after coronavirus risks drove U.S. Treasury yields to historic lows and rate volatility increased sharply, especially from late February to the end of March 2020. In that six-week period, as liquidity became stressed, investors began to liquidate any asset possible, including municipal bonds. Municipal bond prices declined rapidly (and yields spiked higher), 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. Municipal bond prices became severely dislocated from Treasury prices. Credit spreads widened significantly during the March 2020 sell-off, ending the month above their long-term average. Ongoing monetary and fiscal interventions from the Fed and U.S. government helped the market stabilize, then recover over the course of 2020 and early 2021.

Municipal bond gross issuance nationwide remained strong in the reporting period, with deals postponed rather than canceled during the COVID-19 crisis driven sell-off. The overall low level of interest rates has 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

Table of Contents

(all bonds issued less bonds redeemed) is actually much lower than the gross issuance. This lower net issuance was an overall positive technical factor on municipal bond investment performance in recent years. Notably, taxable municipal bond issuance has increased meaningfully since the advent of the Tax Cut and Jobs Act of 2017, which 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 while adding to the scarcity value of tax-exempt issues.

How did the Funds perform during the twelve-month reporting period ended March 31, 2021?

The tables in the Fund Performance, Expense Ratios and Effective Leverage Ratios section of this report provide each Fund’s total return performance information for each share class of the Fund for the period ended March 31, 2021. Each Fund’s Class A Shares at net asset value (NAV) are compared with the performance of its benchmark and corresponding Lipper classification average.

During the reporting period, the Nuveen High Yield Municipal Bond Fund outperformed the S&P Municipal Yield Index, the Nuveen Short Duration High Yield Municipal Bond Fund outperformed the S&P Short Duration Municipal Yield Index and the Nuveen Strategic Municipal Opportunities Fund outperformed the S&P Municipal Bond Index. Meanwhile, the Nuveen High Yield Municipal Bond Fund and Nuveen Strategic Municipal Opportunities Fund outperformed their respective Lipper averages, while the Nuveen Short Duration High Yield Municipal Bond Fund lagged its Lipper average.

What strategies were used to manage the Funds and how did these strategies influence performance during the twelve-month reporting period ended March 31, 2021?

The Nuveen High Yield Municipal Bond Fund and the Nuveen Short Duration High Yield Municipal Bond Fund’s investment objectives are to provide high current income exempt from regular federal income taxes. Capital appreciation is a secondary objective, when consistent with each Fund’s primary objective. The Nuveen Strategic Municipal Opportunities Fund’s investment objective is to seek total return through income exempt from regular federal income taxes and capital appreciation.

Below we highlight the specific factors influencing each Fund’s investment strategy, as well as how we managed each portfolio in light of recent market conditions.

Nuveen High Yield Municipal Bond Fund

The Nuveen High Yield Municipal Bond Fund’s Class A Shares at NAV outperformed the S&P Municipal Yield Index for the twelve-month reporting period ended March 31, 2021.

Municipal bond prices rose during the twelve-month reporting period. The increase accelerated in the late summer 2020 and throughout the rest of the reporting period. Several catalysts triggered these improved market conditions. First, growing investment inflows into the municipal bond asset class led to heightened demand for tax-exempt debt. Second, state and local governments saw their financial position improve due to better-than-expected revenue collections and meaningful federal economic stimulus. Third, positive news surrounding COVID-19 vaccines boosted investors’ confidence. Finally, state and local economies gradually reopened, which lifted the prospects especially for bonds of economically sensitive issuers, including many corporate borrowers and those able to benefit from increased travel spending.

Portfolio Managers’ Comments (continued)

In this strong overall market environment for municipal bond investors, the Fund meaningfully outperformed its benchmark largely due to favorable security selection and sector allocation. Several individual holdings were standout performers for the reporting period.

The Fund’s top contributing holdings included debt of Brightline, a South Florida high-speed passenger rail project. Coming into this reporting period, Brightline bonds had been depressed in value because the rail operator temporarily suspended its service due to the COVID-19 crisis, leading to a short-term revenue decline. The Fund, however, believed the market had overreacted because sections of the project deemed most important to Brightline’s future success remained under construction, which continued uninterrupted throughout the reporting period. As the reporting period progressed, Brightline bonds experienced strong price improvement, as investors became more confident that widespread vaccination would boost mass transit and as the issuer secured nearly $1 billion of additional debt financing.

Holdings in Chicago Board of Education and Chicago general obligation (GO) bonds also contributed to the Fund’s strong performance. These bonds entered the reporting period at relatively low valuations because investors were concerned about how the COVID-19 crisis could worsen Chicago’s preexisting financial challenges. The city, however, weathered the crisis better than expected, as budget adjustments combined with significant federal aid helped stabilize the city and school board’s finances.

The Fund also experienced outperformance from certain industrial development revenue bonds. These securities, issued for corporate borrowers in cyclical (economically sensitive) industries, benefited as expectations for an economic recovery and higher infrastructure spending grew, lifting the price of steel. The Fund has actively purchased municipal bonds of various steel-related companies, which can be eligible for tax-exempt financing of waste-disposal or environmental-cleanup projects. Bonds for U.S. Steel and Big River (a steel project acquired by U.S. Steel) sharply rose for the Fund during the reporting period, as did holdings of Cleveland-Cliffs Inc, another steel company represented in the portfolio.

Security selection in the senior housing bond sector also contributed to performance relative to the index. Relying on thorough credit research, the Fund has a relatively conservative approach to investing in this sector. During the reporting period, the Fund avoided securities of issuers that experienced credit defaults due to the spread of COVID-19, which led to declining occupancy at issuers’ facilities and more financial stress due to high debt levels. Some of these weaker performing securities were represented in the index, so the Fund’s lack of ownership in those bonds contributed to its relative performance.

In sector terms, the Fund’s longtime overweight in real-estate-backed bonds (also known as community-development-district bonds) added value. This sector outperformed on continued strong demand for new suburban single-family homes, which lifted investors’ confidence in the security of the property tax revenues that support these bonds.

The Fund experienced strong absolute returns from its tobacco securitization bond holdings and from its debt affiliated with the U.S. territory of Puerto Rico. However, a modest underweight in each category compared with the benchmark slightly limited the Fund’s relative performance, given the sectors’ robust returns for the twelve-month reporting period.

The Fund’s most notable individual detractors from performance included bonds of Proton Therapy Centers, health care facilities that offer a form of targeted radiation treatment for cancer patients. Due to the impact of the COVID-19 crisis, patient usage of this treatment declined. That, combined with the facilities’ high debt levels, led to negative investor sentiment that weighed on the bonds’ prices. Also detracting were several small positions in industrial development revenue bonds related to pulp and paper and plastic-recycling projects that were underperforming financially even before the COVID-19 crisis.

The Fund benefited from its use of inverse floaters, which can be thought of as long-term bonds whose purchase was partially financed by borrowing against the bonds at short-term interest rates. The Fund’s strategic use of inverse floaters contributed to performance, accruing to both the income and total return of the Fund. The municipal yield curve remained steeply sloped, helping inverse floaters contribute positively along with outperformance in longer dated bonds, while low short-term rates reduced the cost of borrowing and enhanced the performance contribution.

A short position in U.S. Treasury futures used as a hedge against interest rate risk modestly contributed to performance. These positions functioned as intended, enabling the Fund to shorten its portfolio’s effective duration near the desired level while keeping it invested in longer-dated bonds management found attractive. The futures exposure limited the Fund’s performance as interest rates on

Table of Contents

U.S. Treasuries fell sharply during the reporting period. At various times during the reporting period, the Fund used credit default swap contracts to purchase credit protection on certain credits, or to take on credit risk on other credits and earn a commensurate credit spread. Using credit default swaps had a negligible impact on the Fund’s performance during this reporting period.

When this reporting period began, municipal bond investors were seeking to find the market’s bottom amid significant uncertainty. High yield municipal bond funds were transitioning from heavy investment outflows in March 2020 (prior to the start of this reporting period) to more modest outflows in April 2020 to light inflows by May 2020. From May 2020 through the rest of the reporting period, however, accelerated shareholder investments boosted demand for high yield municipal bonds and lifted the market.

During the first half of this reporting period, and particularly early on when the Fund had to meet outflows, management sold a variety of bonds, particularly those with shorter calls and lower yields, which had been relatively resilient during the market’s decline and thus the Fund believed offered less upside potential. This approach enabled the Fund to maintain its desired long-term portfolio composition.

During this period of market weakness, the Fund took advantage of multiple opportunities to invest in issuers whose bond prices had fallen to low levels, in management’s opinion, given the issuers’ underlying credit quality. This decision to position the portfolio more aggressively at a relative low point in the market worked well for the Fund, as many of the bonds added during this time ultimately became strong performers for the full reporting period as fears about COVID-19 crisis eased. Management initially financed these purchases by selling the limited upside bonds previously mentioned. Then, a few months later as shareholder outflows transitioned to strong inflows, the Fund used the proceeds of new investments into the Fund and bond calls and maturities.

During the second half of the reporting period, as the market’s more extreme valuation imbalances normalized, the Fund continued to pursue individual credit opportunities. However, purchase activity turned to a more “everyday” approach during this time. The Fund actively acquired various lower rated real estate backed and charter school bonds and also participated in other areas of the marketplace where management identified an attractive risk/reward trade-off for the Fund’s shareholders.

Impact of the Nuveen High Yield Municipal Bond Fund’s Leveraging Strategy on Performance

One important factor impacting the returns of the Nuveen High Yield Municipal Bond Fund relative to its comparative benchmarks was the Fund’s use of leverage (more detail is provided later in the report) through its investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. The Fund uses leverage because our research has shown that, over time, leveraging provides opportunities for additional income and total returns, particularly in the recent market environment where short term market rates are at or near historical lows, meaning that the short-term rates the Fund has been paying on its leveraging instruments have been lower than the interest the Fund has been earning on its portfolio of long term bonds that it has bought with the proceeds of that leverage. However, use of leverage also exposes the Fund to additional price volatility. When the Fund uses leverage, it will experience a greater increase in its NAV if the municipal bonds acquired through the use of leverage increase in value, but it will also experience a correspondingly larger decline in its NAV if the bonds acquired through leverage decline in value, which will make the Fund’s NAV more volatile, and its total return performance more variable over time. In addition, 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, leverage nevertheless continues to provide the opportunity for incremental income. Management believes that the potential benefits from leverage continue to outweigh the associated increase in risk and volatility previously described. As of March 31, 2021, the effective leverage was 24.9%, which is within our expected range. The Fund's leverage is regularly monitored. The Fund’s use of leverage through inverse floating rate securities contributed positively to performance during this reporting period.

Nuveen Short Duration High Yield Municipal Bond Fund

The Nuveen Short Duration High Yield Municipal Bond Fund’s Class A Shares at NAV outperformed the S&P Short Duration Municipal Yield Index for the twelve-month reporting period ended March 31, 2021.

Portfolio Managers’ Comments (continued)

The Fund’s lower credit quality profile compared to the index drove much of this relative outperformance. Specifically, the Fund’s overweight in lower rated investment grade securities, below investment grade bonds and non-rated bonds contributed to performance, as these lower rated segments outperformed higher quality municipal bonds, particularly as credit spread tightening accelerated from November 2020 through March 2021. The early 2021 introduction of the nearly $2 trillion American Rescue Plan, which earmarked federal aid for state and local governments, combined with improving credit fundamentals for many municipal-debt issuers as the U.S. economy strengthened, ignited robust investor demand for municipal bonds, particularly those in the lower and non-rated credit quality tiers that boasted higher yields. The Fund’s simultaneous underweight in bonds rated AA and A also contributed to relative performance, since these credit tiers lagged the index.

Security selection was another significant source of relative outperformance, reflecting a willingness to own credits that would recover strongly from low valuations due to the sharp market sell-off just before the beginning of the reporting period. Management avoided overreacting to what was believed to be temporary declines in revenues for economically sensitive issuers or to headline risks seen as weighing down bond prices. The Fund focused instead on issuers’ longer-term fundamentals and emphasized credits that, despite their near-term challenges, would maintain sufficient liquidity to meet their financial obligations during the economic slowdown.

Notable individual holdings that added to the Fund's relative performance included certain bonds from the pollution-control, industrial development revenue, transportation and tobacco sectors. The Fund benefited from a position in bonds issued for Cleveland-Cliffs, a steel producer that acquired AK Steel just before the start of the reporting period. The merger allowed both of these medium-sized steel companies to become a larger and more efficient producer that could benefit more fully from rising steel prices as the economy gathered steam. The Fund’s investment in Franklin County Convention Facilities Authority (Columbus, Ohio) bonds also strongly outpaced the index, as the issuer’s fundamental outlook improved.

General obligation (GO) bonds from the City of Chicago and securities from the Chicago Board of Education fared well as the two issuers received a credit rating upgrade. Other standouts included the investment grade securities of the New York Metropolitan Transit Authority and the (Illinois) Metropolitan Pier and Exposition Authority, which recovered strongly as the local economy reopened. GO bonds of Puerto Rico, one of the biggest additions to the Fund this reporting period and one of its largest positions and best performers during the reporting period, was another standout, as investors gained more clarity about the prospects, timing and projected recovery value of the island’s debt restructuring.

The Fund's holdings in Energy Harbor equity (formerly FirstEnergy Solutions) also fared well. The Fund acquired shares in Energy Harbor when its holding of certain municipal bonds issued by FirstEnergy Solutions was converted into Energy Harbor equity as part of FirstEnergy Solutions’ emergence from bankruptcy protection. Although this position underperformed for the Fund overall in the first half of the reporting period, it bounced back strongly in the second half and contributed meaningfully to the Fund’s result.

Partially offsetting this positive performance, however, were the Fund’s holdings in projects that suffered from construction delays or operational challenges, bonds issued by Proton Therapy Centers in Tennessee, Maryland, Georgia and Alabama underperformed on low patient volumes. Other detractors included positions in taxable revenue bonds backed by Tower Health (Pennsylvania), which underperformed financially following its recent merger with another health care system. Bonds backed by the American Dream retail and entertainment project in the Meadowlands (New Jersey) also underperformed, largely because rent and other revenues declined with the facility’s temporary closure during the COVID-19 crisis, although they rebounded strongly after parts of the complex reopened in October 2020.

Meanwhile, sector positioning provided a mixed impact on relative performance. On the positive side, the dedicated-tax and higher education sectors outperformed and the Fund's overweight in these categories proved beneficial. In contrast, a relative underweight in the transportation sector, which also outpaced the index, and overweight in both hospital and utility debt hurt results, as both categories were positive performers that nevertheless trailed the index.

Of final note, the Fund’s duration (interest rate) positioning modestly added value. The Fund was overweight in longer duration bonds within the short duration high yield bond investment universe, which recovered more of their lost value than shorter-duration securities as credit spreads tightened.

Table of Contents

The Fund was an active purchaser of municipal bonds during the reporting period. The exception was early in the reporting period, when high yield municipal bond mutual funds experienced substantial net redemptions, reflecting investors’ growing concern about issuers’ credit quality along with the spread of COVID-19. During that period, the Fund sold bonds to meet these redemptions and, to a far lesser extent, to purchase bonds deemed to be selling at attractive valuations.

By June 2020, shareholder investments into the Fund had returned as investors became more comfortable with municipal issuers’ credit quality. These investment inflows, along with the proceeds of bond calls and maturities, provided ample funds used to purchase many bonds that ended up among the Fund’s best performers for the reporting period. The Fund's purchases typically focused on bonds in the lower investment grade, below investment grade and non-rated credit tiers.

Some of these purchases involved relative value swaps. This strategy entailed selling depreciated bonds with lower yields and buying similarly structured but higher yielding bonds. The Fund implemented this approach to enhance its income earnings capability and seek to make the Fund more tax efficient. The use of credit default swaps had a negligible impact on the Fund's performance during the reporting period.

The Fund managed the duration of its portfolio by shorting interest rate futures contracts. The interest rate futures had negligible impact on the Fund's performance during the reporting period.

The Fund's use of leverage through inverse floating rate securities had a negligible impact on performance over this reporting period.

Nuveen Strategic Municipal Opportunities Fund

The Nuveen Strategic Municipal Opportunities Fund’s Class A Shares at NAV outperformed the S&P Municipal Bond Index for the twelve-month reporting period ended March 31, 2021.

Relative to the benchmark, security selection was the biggest driver of the Fund’s outperformance during this reporting period. The Fund’s top individual contributors included general obligation (GO) bonds issued by the state of California. These securities were purchased early in the reporting period at what management believed were attractive values. In subsequent months, California’s GO debt appreciated strongly as demand for tax-free securities increased and the state’s fiscal picture improved. The Fund sold the bulk of these holdings toward the end of the reporting period after they had reached prices seen as fully valued.

Holdings in Buckeye Tobacco Settlement Financing Authority bonds also performed well, rallying more strongly than the index amid investors’ renewed appetite for higher yielding securities in an improving fundamental and economic environment.

Other top performers contributing to the Fund’s relative outperformance included bonds for Brightline (formerly known as Virgin Trains USA), a South Florida high speed passenger rail project. The bonds recovered as investors became more optimistic about the securities’ potential to weather the COVID-19 crisis. In the industrial development revenue/pollution control sector, municipal bonds issued for U.S. Steel delivered better-than-average gains on an improved economic outlook. Holdings in Energy Harbor equity (formerly FirstEnergy Solutions) also performed well. The Fund acquired shares in Energy Harbor when its holding of certain municipal bonds issued by FirstEnergy Solutions was converted into Energy Harbor equity as part of FirstEnergy Solutions’ emergence from bankruptcy protection. Although this position underperformed for the Fund overall in the first half of the reporting period, it bounced back strongly in the second half of the reporting period and contributed meaningfully to the Fund’s result.

Modestly offsetting these positive security selection results, however, were the Fund’s positions in project revenue bonds backed by specialty cancer treatment centers Georgia Proton Treatment Center and Provision CARES Proton Therapy Center (Florida). These revenue bonds underperformed the index as both centers continued to struggle during the COVID-19 crisis. Additionally, the Fund’s investment in Maryland Stadium Authority bonds, which were hurt by the shutdown of in-person attendance at sporting events, detracted from results versus the benchmark.

Portfolio Managers’ Comments (continued)

The Fund’s duration (interest rate) and yield curve positioning also contributed to performance. During the reporting period, the Fund was consistently positioned with a longer duration and with more exposure to longer-dated securities than the benchmark. This stance helped the Fund maintain its yield, and these securities outperformed the benchmark as municipal interest rates declined through most of the reporting period. The Fund was underweight in shorter-dated securities, which lagged longer-term bonds, was also helpful.

Management gradually shortened the Fund’s duration by the end of the reporting period, selling longer-dated holdings and shorting U.S. Treasury futures in anticipation of rising market yields. When yields moved higher in the final months of the reporting period, this duration and yield curve adjustment further helped relative performance. The use of certain floating rate securities, including tender option bonds (TOBs), also modestly boosted the Fund’s performance.

The Fund was well positioned from a credit quality perspective. Early in the reporting period, management added to the Fund’s holdings in below investment grade securities (rated BB and below, including non-rated bonds). These bonds outpaced investment grade bonds by a wide margin and thus made a strong performance contribution. Within the investment grade credit tiers, the Fund also benefited from being overweight lower rated securities (A and BBB), which outpaced the higher grade rating categories (AAA and AA) in which the Fund was underweight.

Sector positioning was another positive performance factor, especially the Fund’s overweight in higher yielding segments that bounced back most strongly from the market’s March 2020 lows. Specifically, the Fund was overweight in the tobacco, airport, toll-roads, health care, and dedicated-tax sectors, which contributed to performance versus the benchmark. Additionally, the Fund was underweight in the state and local general obligation and pre-refunded sectors, which was also beneficial, as these generally higher quality categories underperformed the index. However, the Fund’s underweight in higher education modestly detracted, given this sector’s outperformance, as did an overweight in electric utility bonds and lease-backed debt, which lagged this reporting period.

Early in the reporting period, the Fund, mirroring the broad municipal bond market, experienced investment outflows following the steep market decline in mid-March 2020. To satisfy these shareholder redemptions, management sold higher quality, shorter-duration bonds, which had held more of their value than comparable lower quality, longer dated issues during the market’s early-spring decline. With these sales, made at a loss, management harvested tax losses, enhancing the Fund’s income earning capability and sought to make the portfolio more tax efficient.

As the municipal market exhibited signs of stabilization by mid-spring 2020, management’s focus quickly shifted toward relative value opportunities. The Fund exchanged certain lower yielding bonds for similar higher yielding securities with attractive valuations, often from the same issuer.

When the municipal market stabilized further and shareholder inflows returned to the Fund by May 2020, management became active purchasers of creditworthy opportunities it identified in the marketplace, particularly among below investment grade securities in the sectors hit hardest by COVID-19 crisis related concerns. Typically, new bond acquisitions were also longer dated securities.

At various times during the reporting period, the Fund used credit default swap contracts to purchase credit protection on certain credits, or to take on credit risk on other credits and earn a commensurate credit spread. The use of credit default swaps had a negligible impact on the Fund's performance during the reporting period.

Risk Considerations and Dividend Information

Risk Considerations

Nuveen High Yield Municipal Bond Fund

Mutual fund investing involves risk; principal loss is possible. Debt or fixed income securities such as those held by the Fund, are subject to market risk, credit risk, interest rate risk, call risk, state concentration risk, tax risk, political and economic risk, and income risk. As interest rates rise, bond prices fall. Credit risk refers to an issuers ability to make interest and principal payments when due. The Fund concentrates in non-investment grade and unrated bonds with long maturities and durations which carry heightened credit risk, liquidity risk, and potential for default. In addition, the Fund oftentimes engages in a significant amount of portfolio leverage and in doing so, assumes a high level of risk in pursuit of its objectives. Leverage involves the risk that the Fund could lose more than its original investment and also increases the Fund’s exposure to volatility, interest rate risk and credit risk.

The Fund’s use of leverage creates the possibility of higher volatility for the Fund’s per share net asset value (NAV), market price, distributions and returns. There is no assurance that the Fund’s leveraging strategy will be successful.

Nuveen Strategic Municipal Opportunities Fund

Mutual fund investing involves risk; principal loss is possible. There is no guarantee the Fund’s investment objectives will be achieved. The Fund is subject to interest rate risk; as interest rates rise, bond prices fall. Credit risk arises from an issuer’s ability to make interest and principal payments when due, as well as the prices of bonds declining when an issuer’s credit quality is expected to deteriorate. The use of derivatives involves substantial financial risks and transaction costs. Investments in below investment grade or high yield securities are subject to liquidity risk and heightened credit risk. The Fund’s use of inverse floaters creates effective leverage. The Fund periodically engages in a significant amount of portfolio leverage and in doing so, assumes a higher level of risk in pursuit of its objectives. Leverage involves the risk that the Fund could lose more than its original investment and also increases the Fund’s exposure to volatility, interest rate risk and credit risk. These and other risk considerations, such as alternative minimum tax, call, defaulted bond, income, municipal bond market liquidity, municipal lease obligations, other investment companies, political and economic, tax, and zero coupon bonds risks, are described in detail in the Fund’s prospectus.

Yields as of March 31, 2021

Dividend Yield is the most recent dividend per share (annualized) divided by the offering price per share.

The Taxable-Equivalent Yield represents the yield that must be earned on a fully taxable investment in order to equal the yield of the Fund on an after-tax basis at an assumed tax rate. Your actual combined federal and state income tax rates may differ from the assumed rate. Taxable-Equivalent Yield also takes into account the percentage of the Fund’s income generated and paid by the Fund (based on payments made during the previous calendar year) that was either exempt from federal income tax but not from state income tax (e.g., income from an out-of-state municipal bond), or was exempt from neither federal nor state income tax. Separately, if the comparison were instead to investments that generate qualified dividend income, which is taxable at a rate lower than an individual’s ordinary graduated tax rate, the fund’s Taxable-Equivalent Yield would be lower.

1 The SEC Yield for Class A shares quoted in the table reflects the maximum sales load. Investors paying a reduced load because of volume discounts, investors paying no load because they qualify for one of the several exclusions from the load and existing shareholders who previously paid a load but would like to know the SEC Yield applicable to their shares on a going-forward basis, should understand that the SEC Yield effectively applicable to them would be higher than the figure quoted in the table.

2 The Taxable-Equivalent Yield is based on the Fund’s SEC 30-Day Yield on the indicated date and a federal income tax rate shown in the respective table above.

Every 30 days, a quarter of the preferred stock was converted to AAL common stock based on the 5-day volume-weighted average price and the amount of preferred shares tendered during the optional preferred conversion period.

(15)	For fair value measurement disclosure purposes, investment classified as Level 2. See Notes to Financial Statements, Note 3 - Investment Valuation and Fair Value Measurements for more information.
(16)	Investment, or a portion of investment, is out on loan for securities lending. The total value of the securities out on loan as of the end of the reporting period was $6,661,407.
(17)	Senior loans generally pay interest at rates which are periodically adjusted by reference to a base short-term, floating lending rate (Reference Rate) plus an assigned fixed rate (Spread). These floating lending rates are generally (i) the lending rate referenced by the London Inter-Bank Offered Rate (“LIBOR”), or (ii) the prime rate offered by one or more major United States banks. Senior loans may be considered restricted in that the Fund ordinarily is contractually obligated to receive approval from the agent bank and/or borrower prior to the disposition of a senior loan. The rate shown is the coupon as of the end of the reporting period.
(18)	Senior Loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for a borrower to prepay, prepayments of senior loans may occur. As a result, the actual remaining maturity of senior loans held may be substantially less than the stated maturities shown.
(19)	Senior loan received as part of the bankruptcy settlement during March 2021 for Pennsylvania Economic Development Financing Authority, Solid Waste Disposal Revenue Bonds, CarbonLITE P, LLC Project, Series 2019, 5.250%, 6/01/26 (AMT), 144A and Senior loan received as part of the bankruptcy settlement during March 2021 for Pennsylvania Economic Development Financing Authority, Solid Waste Disposal Revenue Bonds, CarbonLITE P, LLC Project, Series 2019, 5.750%, 6/01/36 (AMT), 144A
(20)	Senior loan received as part of the bankruptcy settlement during March 2021 for Mission Economic Development Corporation, Texas, Water Supply Revenue Bonds, CarbonLITE Recycling, LLC Project, Series 2016, 6.500%, 12/01/33, 144A (AMT).
(21)	The Fund may loan securities representing up to one third of the fair value of its total assets (which includes collateral for securities on loan) to broker dealers, banks, and other institutions. The Fund maintains collateral equal to at least 100% of the fair value of the securities loaned. The cash collateral received by the Fund is invested in this money market fund. See Notes to Financial Statements, Note 4- Portfolio Securities and Investments in Derivatives for more information.
(22)	The rate shown is the one-day yield as of the end of the reporting period.
(23)	Investment has a maturity of greater than one year, but has variable rate and/or demand features which qualify it as a short-term investment. The rate disclosed, as well as the reference rate and spread, where applicable, is that in effect as of the end of the reporting period. This rate changes periodically based on market conditions or a specified market index.
(24)	Other assets less liabilities includes the unrealized appreciation (depreciation) of certain over-the-counter ("OTC") derivatives as presented on the Statement of Assets and Liabilities, when applicable. The unrealized appreciation (depreciation) of OTC cleared and exchange-traded derivatives is recognized as part of the cash collateral at brokers and/or the receivable or payable for variation margin as presented on the Statement of Assets and Liabilities, when applicable.
(25)	The Fund entered into the credit default swap to gain investment exposure to the referenced entity. Selling protection has a similar credit risk position to owning the referenced entity. Buying protection has a similar credit risk position to selling the referenced entity short.
(26)	The credit spread generally serves as an indication of the current status of the payment/performance risk and therefore the likelihood of default of the credit derivative. The credit spread also reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into a credit default swap contract. Higher credit spreads are indicative of higher likelihood of performance by the seller of protection.
144A	Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.
AMT	Alternative Minimum Tax
ETM	Escrowed to maturity
IF	Inverse floating rate security issued by a tender option bond (“TOB”) trust, the interest rate on which varies inversely with the Securities Industry Financial Markets Association (SIFMA) short-term rate, which resets weekly, or a similar short-term rate, and is reduced by the expenses related to the TOB trust.
N/A	Not Applicable.

(10)	For fair value measurement disclosure purposes, investment classified as Level 2. See Notes to Financial Statements, Note 3 - Investment Valuation and Fair Value Measurements for more information.
(11)	Non-income producing; issuer has not declared an ex-dividend date within the past twelve months.
(12)	Investment, or a portion of investment, is out on loan for securities lending. The total value of the securities out on loan as of the end of the reporting period was $14,726,242.
(13)	Senior loans generally pay interest at rates which are periodically adjusted by reference to a base short-term, floating lending rate (Reference Rate) plus an assigned fixed rate (Spread). These floating lending rates are generally (i) the lending rate referenced by the London Inter-Bank Offered Rate (“LIBOR”), or (ii) the prime rate offered by one or more major United States banks. Senior loans may be considered restricted in that the Fund ordinarily is contractually obligated to receive approval from the agent bank and/or borrower prior to the disposition of a senior loan. The rate shown is the coupon as of the end of the reporting period.

Table of Contents

(14)	Senior Loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for a borrower to prepay, prepayments of senior loans may occur. As a result, the actual remaining maturity of senior loans held may be substantially less than the stated maturities shown.
(15)	Senior loan received as part of the bankruptcy settlement during March 2021 for Pennsylvania Economic Development Financing Authority, Solid Waste Disposal Revenue Bonds, CarbonLITE P, LLC Project, Series 2019, 5.250%, 6/01/26 (AMT), 144A and Senior loan received as part of the bankruptcy settlement during March 2021 for Pennsylvania Economic Development Financing Authority, Solid Waste Disposal Revenue Bonds, CarbonLITE P, LLC Project, Series 2019, 5.750%, 6/01/36 (AMT), 144A
(16)	Senior loan received as part of the bankruptcy settlement during March 2021 for Mission Economic Development Corporation, Texas, Water Supply Revenue Bonds, CarbonLITE Recycling, LLC Project, Series 2016, 6.500%, 12/01/33, 144A (AMT).
(17)	The Fund may loan securities representing up to one third of the fair value of its total assets (which includes collateral for securities on loan) to broker dealers, banks, and other institutions. The Fund maintains collateral equal to at least 100% of the fair value of the securities loaned. The cash collateral received by the Fund is invested in this money market fund. See Notes to Financial Statements, Note 4- Portfolio Securities and Investments in Derivatives for more information.
(18)	The rate shown is the one-day yield as of the end of the reporting period.
(19)	Investment has a maturity of greater than one year, but has variable rate and/or demand features which qualify it as a short-term investment. The rate disclosed, as well as the reference rate and spread, where applicable, is that in effect as of the end of the reporting period. This rate changes periodically based on market conditions or a specified market index.
(20)	Other assets less liabilities includes the unrealized appreciation (depreciation) of certain over-the-counter ("OTC") derivatives as presented on the Statement of Assets and Liabilities, when applicable. The unrealized appreciation (depreciation) of OTC cleared and exchange-traded derivatives is recognized as part of the cash collateral at brokers and/or the receivable or payable for variation margin as presented on the Statement of Assets and Liabilities, when applicable.
(21)	The Fund entered into the credit default swap to gain investment exposure to the referenced entity. Selling protection has a similar credit risk position to owning the referenced entity. Buying protection has a similar credit risk position to selling the referenced entity short.
(22)	The credit spread generally serves as an indication of the current status of the payment/performance risk and therefore the likelihood of default of the credit derivative. The credit spread also reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into a credit default swap contract. Higher credit spreads are indicative of higher likelihood of performance by the seller of protection.
144A	Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.
AMT	Alternative Minimum Tax
ETM	Escrowed to maturity
IF	Inverse floating rate security issued by a tender option bond (“TOB”) trust, the interest rate on which varies inversely with the Securities Industry Financial Markets Association (SIFMA) short-term rate, which resets weekly, or a similar short-term rate, and is reduced by the expenses related to the TOB trust.
LIBOR	London Inter-Bank Offered Rate
N/A	Not Applicable.
SIFMA	Securities Industry and Financial Market Association
UB	Underlying bond of an inverse floating rate trust reflected as a financing transaction. See Notes to Financial Statements, Note 4 – Portfolio Securities and Investments in Derivatives for more information.
WI/DD	Purchased on a when-issued or delayed delivery basis.

See accompanying notes to financial statements.

Nuveen Strategic Municipal Opportunities Fund (continued)

Portfolio of Investments March 31, 2021

(1)	All percentages shown in the Portfolio of Investments are based on net assets.
(2)	Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. Optional Call Provisions are not covered by the report of independent registered public accounting firm.
(3)	The ratings disclosed are the lowest of Standard & Poor’s Group (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”) rating. Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated by any of these national rating agencies. Ratings are not covered by the report of independent registered public accounting firm.
(4)	Investment, or portion of investment, has been pledged to collateralize the net payment obligations for investments in inverse floating rate transactions.
(5)	Step-up coupon bond, a bond with a coupon that increases ("steps up"), usually at regular intervals, while the bond is outstanding. The rate shown is the coupon as of the end of the reporting period.
(6)	Defaulted security. A security whose issuer has failed to fully pay principal and/or interest when due, or is under the protection of bankruptcy.
(7)	Variable rate security. The rate shown is the coupon as of the end of the reporting period.
(8)	Investment valued at fair value using methods determined in good faith by, or at the discretion of, the Board. For fair value measurement disclosure purposes, investment classified as Level 3. See Notes to Financial Statements, Note 3 - Investment Valuation and Fair Value Measurements for more information.
(9)	Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities, which ensure the timely payment of principal and interest.
(10)	Common Stock received as part of the bankruptcy settlements during February 2020 for Ohio Air Quality Development Authority, Ohio, Air Quality Development Revenue Bonds, FirstEnergy Generation Corporation Project, Series 2009A, 5.700%, 8/01/20; Ohio Air Quality Development Authority, Ohio, Pollution Control Revenue Bonds, FirstEnergy Nuclear Generation Project, Refunding Series 2008B, 3.625%, 10/01/33; Ohio Air Quality Development Authority, Ohio, Pollution Control Revenue Bonds, FirstEnergy Nuclear Generation Project, Refunding Series 2008C, 3.950%, 11/01/32; Ohio Water Development Authority, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generating Corporation Project, Series 2006A, 3.000%, 5/15/19; Ohio Water Development Authority, Pollution Control Revenue Refunding Bonds, FirstEnergy Nuclear Generating Corporation Project, Series 2008B, 3.625%, 10/01/33.
(11)	For fair value measurement disclosure purposes, investment classified as Level 2. See Notes to Financial Statements, Note 3 - Investment Valuation and Fair Value Measurements for more information.
(12)	Non-income producing; issuer has not declared an ex-dividend date within the past twelve months.
(13)	Senior loans generally pay interest at rates which are periodically adjusted by reference to a base short-term, floating lending rate (Reference Rate) plus an assigned fixed rate (Spread). These floating lending rates are generally (i) the lending rate referenced by the London Inter-Bank Offered Rate (“LIBOR”), or (ii) the prime rate offered by one or more major United States banks. Senior loans may be considered restricted in that the Fund ordinarily is contractually obligated to receive approval from the agent bank and/or borrower prior to the disposition of a senior loan. The rate shown is the coupon as of the end of the reporting period.
(14)	Senior Loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for a borrower to prepay, prepayments of senior loans may occur. As a result, the actual remaining maturity of senior loans held may be substantially less than the stated maturities shown.
(15)	Senior loan received as part of the bankruptcy settlement during March 2021 for Mission Economic Development Corporation, Texas, Water Supply Revenue Bonds, CarbonLITE Recycling, LLC Project, Series 2016, 6.500%, 12/01/33, 144A (AMT).
(16)	Investment has a maturity of greater than one year, but has variable rate and/or demand features which qualify it as a short-term investment. The rate disclosed, as well as the reference rate and spread, where applicable, is that in effect as of the end of the reporting period. This rate changes periodically based on market conditions or a specified market index.
(17)	Other assets less liabilities includes the unrealized appreciation (depreciation) of certain over-the-counter ("OTC") derivatives as presented on the Statement of Assets and Liabilities, when applicable. The unrealized appreciation (depreciation) of OTC cleared and exchange-traded derivatives is recognized as part of the cash collateral at brokers and/or the receivable or payable for variation margin as presented on the Statement of Assets and Liabilities, when applicable.
(18)	The Fund entered into the credit default swap to gain investment exposure to the referenced entity. Selling protection has a similar credit risk position to owning the referenced entity. Buying protection has a similar credit risk position to selling the referenced entity short.
(19)	The credit spread generally serves as an indication of the current status of the payment/performance risk and therefore the likelihood of default of the credit derivative. The credit spread also reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into a credit default swap contract. Higher credit spreads are indicative of higher likelihood of performance by the seller of protection.
144A	Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.
AMT	Alternative Minimum Tax
LIBOR	London Inter-Bank Offered Rate
N/A	Not Applicable.
UB	Underlying bond of an inverse floating rate trust reflected as a financing transaction. See Notes to Financial Statements, Note 4 – Portfolio Securities and Investments in Derivatives for more information.
WI/DD	Purchased on a when-issued or delayed delivery basis.

See accompanying notes to financial statements.

(a)	Per share Net Investment Income (Loss) is calculated using the average daily shares method.
(b)	Total return is the combination of changes in NAV without any sales charge, reinvested dividend income at NAV and reinvested capital gains distributions at NAV, if any. Total returns are not annualized.
(c)	The expense ratios reflect, among other things, the interest expense deemed to have been paid by the Fund on the floating rate certificates issued by the special purpose trusts for the self-deposited inverse floaters held by the Fund, where applicable, as described in Note 4 – Portfolio Securities and Investments in Derivatives and the interest expense and fees paid on borrowings, as described in Note 9 - Borrowing Arrangements.
(d)	Portfolio Turnover Rate is calculated based on the lesser of long-term purchases or sales (as disclosed in Note 4 – Portfolio Securities and Investments in Derivatives) divided by the average long-term market value during the period.
(e)	For the eleven months ended March 31, 2017.
(f)	For the period June 30, 2016 (commencement of operations) through March 31, 2017.

Notes to Financial Statements

1. General Information

Trust and Fund Information

The Nuveen Municipal Trust (the “Trust”), is an open-end management investment company registered under the Investment Company Act of 1940 (the “1940 Act”), as amended. The Trust is comprised of Nuveen High Yield Municipal Bond Fund (“High Yield”), Nuveen Short Duration High Yield Municipal Bond Fund (“Short Duration High Yield”) and Nuveen Strategic Municipal Opportunities Fund (“Strategic Municipal Opportunities”) (each a “Fund” and collectively, the “Funds”), as diversified funds, among others. The Trust was organized as a Massachusetts business trust on July 1, 1996.

The end of the reporting period for the Funds is March 31, 2021, and the period covered by these Notes to Financial Statements is the fiscal year ended March 31, 2021 (the "current fiscal period”).

Investment Adviser and Sub-Adviser

The Funds' investment adviser is Nuveen Fund Advisors, LLC (the “Adviser”), a subsidiary of Nuveen, LLC (“Nuveen”). Nuveen is the investment management arm of Teachers Insurance and Annuity Association of America (TIAA). The Adviser has overall responsibility for management of the Funds, oversees the management of the Funds' portfolios, manages the Funds' business affairs and provides certain clerical, bookkeeping and other administrative services, and, if necessary, asset allocation decisions. The Adviser has entered into sub-advisory agreements with Nuveen Asset Management, LLC, (the “Sub-Adviser”), a subsidiary of the Adviser, under which the Sub-Adviser manages the investment portfolios of the Funds.

Share Classes and Sales Charges

Class A Shares are generally sold with an up-front sales charge. Class A Share purchases of $500,000 or more for High Yield and $250,000 or more for Short Duration High Yield and Strategic Municipal Opportunities are sold at net asset value (“NAV”) without an up-front sales charge but may be subject to a contingent deferred sales charge (“CDSC”) of 1% for High Yield and Strategic Municipal Opportunities and 0.70% for Short Duration High Yield if redeemed within eighteen months of purchase. Class C Shares are sold without an up-front sales charge. The Funds will issue class C2 Shares upon the exchange of Class C2 Shares from another Nuveen municipal bond fund or for the purposes of dividend reinvestment, but Class C2 Shares are not available for new accounts or for additional investment into existing accounts. Class C and C2 Shares are subject to a CDSC of 1% if redeemed within twelve months of purchase. Class C and Class C2 Shares automatically convert to Class A Shares eight years (ten years prior to March 1, 2021) after purchase. Class R6 Shares and Class I Shares are sold without an upfront sales charge.

Reimbursement from the Adviser

During the current fiscal period, the Adviser reimbursed High Yield and Short Duration High Yield for losses resulting from net asset value (“NAV”) errors that occurred during the current and prior fiscal periods. Such amounts are recognized as “Capital contribution from the Adviser” on the Statement of Changes in Net Assets.

Other Matters

The outbreak of the novel coronavirus (“COVID-19”) and subsequent global pandemic began significantly impacting the U.S. and global financial markets and economies during the calendar quarter ended March 31, 2020. The worldwide spread of COVID-19 has created significant uncertainty in the global economy. The duration and extent of COVID-19 over the long-term cannot be reasonably estimated at this time. The ultimate impact of COVID-19 and the extent to which COVID-19 impacts the Funds’ normal course of business, results of operations, investments, and cash flows will depend on future developments, which are highly uncertain and difficult to predict. Management continues to monitor and evaluate this situation.

2. Significant Accounting Policies

342

Table of Contents

Compensation

The Trust pays no compensation directly to those of its trustees who are affiliated with the Adviser or to its officers, all of whom receive remuneration for their services to the Trust from the Adviser or its affiliates. The Funds' Board of Trustees (the "Board") has adopted a deferred compensation plan for independent trustees that enables trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen-advised funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen-advised funds.

Distributions to Shareholders

Indemnifications

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

Investments and Investment Income

Securities transactions are accounted for as of the trade date for financial reporting purposes. Realized gains and losses on securities transactions are based upon the specific identification method. Investment income is comprised of dividend income and interest income. Dividend income is recorded on the ex-dividend date. Non-cash dividends received the form of stock, if any, are recognized on the ex-dividend date and recorded at fair value. Interest income, which is recorded on an accrual basis and includes the accretion of discounts and the amortization of premiums for financial reporting purposes. Interest income also reflects payment-in-kind ("PIK") interest and paydown gains and losses, if any. PIK interest represents income received in the form of securities in lieu of cash. Securities lending income is comprised of fees earned from borrowers and income earned on cash collateral investments.

Multiclass Operations and Allocations

Sub-transfer agent fees and similar fees, which are recognized as a component of “Shareholder servicing agent fees” on the Statement of Operations, are not charged to Class R6 Shares and are prorated among the other classes based on their relative settled shares.

Realized and unrealized capital gains and losses of the Funds are prorated among the classes based on the relative net assets of each class.

Netting Agreements

In the ordinary course of business, the Funds may enter into transactions subject to enforceable International Swaps and Derivatives Association, Inc. (ISDA) master agreements or other similar arrangements (“netting agreements”). Generally, the right to offset in netting agreements allows each Fund to offset certain securities and derivatives with a specific counterparty, when applicable, as well as any collateral received or delivered to that counterparty based on the terms of the agreements. Generally, each Fund manages its cash collateral and securities collateral on a counterparty basis.

The Funds' investments subject to netting agreements as of the end of the reporting period, if any, are further described in Note 4 - Portfolio Securities and Investments in Derivatives.

New Accounting Pronouncements and Rule Issuances

Reference Rate Reform

In March 2020, FASB issued Accounting Standards Update ("ASU") 2020-04, Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The main objective of the new guidance is to provide relief to companies that will be impacted by the expected change in benchmark interest rates, when participating banks will no longer be required to submit London Interbank Offered Rate (LIBOR) quotes by the UK Financial Conduct Authority (FCA). The new guidance allows companies to, provided the only change to existing contracts are a change to an approved benchmark interest rate, account for modifications as a continuance of the existing contract without additional analysis. For new and existing contracts, the Funds may elect to apply the amendments as of March 12, 2020 through December 31, 2022. Management has not yet elected to apply the amendments, is continuously evaluating the potential effect a discontinuation of LIBOR could have on the Funds’ investments and has currently determined that it is unlikely the ASU’s adoption will have a significant impact on the Funds’ financial statements and various filings.

Securities and Exchange Commission (“SEC”) Adopts New Rules to Modernize Fund Valuation Framework

3. Investment Valuation and Fair Value Measurements

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, credit spreads, etc.).

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

A description of the valuation techniques applied to the Funds’ major classifications of assets and liabilities measured at fair value follows:

Equity securities and exchange-traded funds listed or traded on a national market or exchange are valued based on their sale price at the official close of business of such market or exchange on the valuation date. Foreign equity securities are registered investment companies that trade on a foreign exchange are valued at the last sale price or official closing price reported on the exchange where traded and converted to U.S. dollars at the prevailing rates of exchange on the date of valuation. To the extent these securities are actively traded and that valuation adjustments are not applied, they are generally classified as Level 1. If there is no official close of business, then the latest available sale price is utilized. If no sales are reported, then the mean of the latest available bid and ask prices is utilized and these securities are generally classified as Level 2.

Swap contracts are marked-to-market daily based upon a price supplied by a pricing service. Swaps are generally classified as Level 2.

Futures contracts are valued using the closing settlement price or, in the absence of such a price, the last traded price and are generally classified as Level 1.

The following table summarizes the market value of the Funds' investments as of the end of the reporting period, based on the inputs used to value them:

Securities Lending

Effective August 14, 2020, High Yield and Short Duration High Yield may lend securities representing up to one-third of the value of its total assets to broker-dealers, banks, and other institutions in order to generate additional income. When loaning securities, each Fund retains the benefits of owning the securities, including the economic equivalent of dividends or interest generated by the security. The loans are continuous, can be recalled at any time, and have no set maturity. The Funds’ custodian, State Street Bank and Trust Company, serves as the securities lending agent (the “Agent”).

When a Fund loans its portfolio securities, it will receive, at the inception of each loan, cash collateral equal to an amount not less than 100% of the market value of the loaned securities. The actual percentage of the cash collateral will vary depending upon the asset type of the loaned securities. Collateral for the loaned securities is invested in a government money market fund maintained by the Agent, which is subject to the requirements of Rule 2a-7 under the 1940 Act. The value of the loaned securities and the liability to return the cash collateral received are recognized on the Statement of Assets and Liabilities. If the market value of the loaned securities increases, the borrower must furnish additional collateral to the Fund, which is also recognized on the Statement of Assets and Liabilities. Securities out on loan are subject to termination at any time at the option of the borrower or the Fund. Upon termination, the borrower is required to return to the Fund securities identical to the securities loaned. During the term of the loan, the Fund bears the market risk with respect to the investment of collateral and the risk that the Agent may default on its contractual obligations to the Fund. The Agent bears the risk that the borrower may default on its obligation to return the loaned securities as the Agent is contractually obligated to indemnify the Fund if at the time of a default by a borrower some or all of the loan securities have not been returned.

347

Table of Contents

Notes to Financial Statements (continued)

Securities lending income recognized by a Fund consists of earnings on invested collateral and lending fees, net of any rebates to the borrower and compensation to the Agent. Such income is recognized on the Statement of Operations.

As of the end of the reporting period, the total value of the loaned securities and the total value of collateral received were as follows:

Fund	Asset Class out on Loan	Long-Term Investments, at Value	Total Collateral Received
High Yield	Corporate Bonds	$ 6,661,407	$ 6,864,513
Short Duration High Yield	Corporate Bonds	$14,726,242	$14,914,769

Zero Coupon Securities

Investment Transactions

Long-term purchases and sales (including maturities but excluding derivative transactions and securities purchased with collateral from securities lending where applicable) during the current fiscal period were as follows:

	High Yield	Short Duration High Yield	Strategic Municipal Opportunities
Purchases	$4,456,362,330	$1,354,945,020	$1,092,507,800
Sales and maturities	4,485,254,328	2,087,273,351	527,419,527

Investments in Derivatives

Futures Contracts

Upon execution of a futures contract, a Fund is obligated to deposit cash or eligible securities, also known as “initial margin,” into an account at its clearing broker equal to a specified percentage of the contract amount. Cash held by the broker to cover initial margin requirements on open futures contracts, if any, is recognized as “Cash collateral at brokers for investments in futures contracts” on the Statement of Assets and Liabilities. Investments in futures contracts obligate a Fund and the clearing broker to settle monies on a daily basis representing changes in the prior days “mark-to-market” of the open contracts. If a Fund has unrealized appreciation the clearing broker would credit the Fund’s account with an amount equal to appreciation and conversely if a Fund has unrealized depreciation the clearing broker would debit the Fund’s account with an amount equal to depreciation. These daily cash settlements are also known as “variation margin.” Variation margin is recognized as a receivable and/or payable for “Variation margin on futures contracts” on the Statement of Assets and Liabilities.

During the current fiscal period, the Funds managed the duration of their respective portfolios by shorting interest rate futures contracts.

348

Table of Contents

The average notional amount of futures contracts outstanding during the current fiscal period was as follows:

	High Yield	Short Duration High Yield	Strategic Municipal Opportunities
Average notional amount of futures contracts outstanding*	$1,723,460,176	$449,587,186	$33,580,506

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

The following table presents the fair value of all futures contracts held by the Fund as of the end of the reporting period, the location of these instruments on the Statement of Assets and Liabilities and the primary underlying risk exposure.

Credit Default Swap Contracts

A Fund may enter into a credit default swap contract to seek to maintain a total return on a particular investment or portion of its portfolio, or to take an active long or short position with respect to the likelihood of a particular issuer’s default. Credit default swap contracts involve one party making a stream of payments to another party in exchange for the right to receive a specified return if/when there is a credit event by a third party. Generally, a credit event means bankruptcy, failure to pay, or restructuring. The specific credit events applicable for each credit default swap are stated in the terms of the particular swap agreement. When a Fund has bought (sold) protection in a credit default swap upon occurrence of a specific credit event with respect to the underlying referenced entity, the Fund will either (i) deliver (receive) that security, or an equivalent amount of cash, from the counterparty in exchange for receipt (payment) of the notional amount to the counterparty, or (ii) receive (pay) a net settlement amount of the credit default swap contract less the recovery value of the referenced obligation or underlying securities comprising the referenced index. The difference between the value of the security received (delivered) and the notional amount delivered (received) is recorded as a realized gain or loss. Payments paid (received) at the beginning of the measurement period are recognized as a component of “Credit default swaps premiums paid and/or received” on the Statement of Assets and Liabilities, when applicable.

Credit default swap contracts are valued daily. Changes in the value of a credit default swap during the fiscal period are recognized as a component of “Change in net unrealized appreciation (depreciation) of swaps” and realized gains and losses are recognized as a component of “Net realized gain (loss) from swaps” on the Statement of Operations.

For OTC swaps not cleared through a clearing house (“OTC Uncleared”), the daily change in the market value of the swap contract, along with any daily interest fees accrued, are recognized as components of “Unrealized appreciation or depreciation on credit default swaps” on the Statement of Assets and Liabilities.

Cash held by the broker to cover initial margin requirements on open swap contracts, if any, is recognized as “Cash collateral at brokers for investments in swaps” on the Statement of Assets and Liabilities. Investments in OTC Cleared swaps obligate a Fund and the clearing broker to settle monies on a daily basis representing changes in the prior day’s “mark-to-market” of the swap. If a Fund has unrealized appreciation the clearing broker would credit the Fund’s account with an amount equal to the appreciation and conversely if a Fund has unrealized depreciation the clearing broker would debit a Fund’s account with an amount equal to the depreciation. These daily cash settlements are also known as “variation margin.” Variation margin for OTC Cleared swaps is recognized as a receivable and/or payable for “Variation margin on swap contracts” on the Statement of Assets and Liabilities. Upon the execution of an OTC Uncleared swap, neither the Fund nor the counterparty is required to deposit initial margin as the trades are recorded bilaterally between both parties to the swap contract, and the terms of the variation margin are subject to a predetermined threshold negotiated by the Fund and the counterparty. Variation margin for OTC Uncleared swaps is recognized as a component of “Unrealized appreciation or depreciation on credit default swaps” as described in the preceding paragraph. The maximum potential amount of future payments the Fund could incur as a buyer or seller of protection in a credit default swap contract is limited to the notional amount of the contract. The maximum potential amount would be offset by the recovery value, if any, of the respective referenced entity.

During the current fiscal period, the Funds used credit default swap contracts to purchase credit protection on certain credits, or to take on credit risk on other credits and earn a commensurate credit spread.

The average notional amount of credit default swap contracts outstanding during the current fiscal period was as follows:

	High Yield	Short Duration High Yield	Strategic Municipal Opportunities
Average notional amount of credit default swap contracts outstanding^*	$181,000,000	$10,000,000	$2,500,000

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

The following table presents the fair value of all swap contracts held by the Funds as of the end of the reporting period, the location of these instruments on the Statement of Assets and Liabilities and the primary underlying risk exposure.

6. Income Tax Information

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all of its net investment income and net capital gains to shareholders and to otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. Therefore, no federal income tax provision is required. Furthermore, each Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from regular federal and designated state income taxes, to retain such tax-exempt status when distributed to shareholders of the Funds. Net realized capital gains and ordinary income distributions paid by the Funds are subject to federal taxation.

The table below presents the cost and unrealized appreciation (depreciation) of each Fund's investment portfolio, as determined on a federal income tax basis, as of March 31, 2021.

	High Yield	Short Duration High Yield	Strategic Municipal Opportunities
Tax cost of investments	$18,308,337,071	$4,359,057,734	$1,200,934,395
Gross unrealized:
Appreciation	$ 2,275,320,284	$ 279,202,960	$ 61,658,863
Depreciation	(598,420,208)	(116,481,822)	(8,945,703)
Net unrealized appreciation (depreciation) of investments	$ 1,676,900,076	$ 162,721,138	$ 52,713,160

Permanent differences, primarily due to investments in partnerships, taxable market discount, paydowns and treatment of notional principal contracts, resulted in reclassifications among the Funds’ components of net assets as of March 31, 2021, the Funds' tax year end.

The tax components of undistributed net tax-exempt income, net ordinary income and net long-term capital gains as of March 31, 2021, the Funds' tax year end, were as follows:

The annual complex-level fee, payable monthly, for each Fund is calculated according to the following schedule:

Complex-Level Eligible Asset Breakpoint Level*	Effective Complex-Level Fee Rate at Breakpoint Level
$55 billion	0.2000%
$56 billion	0.1996
$57 billion	0.1989
$60 billion	0.1961
$63 billion	0.1931

$125 billion	0.1599
$200 billion	0.1505
$250 billion	0.1469
$300 billion	0.1445

* The complex-level fee is calculated based upon the aggregate daily “eligible assets” of all Nuveen open-end and closed-end funds. Eligible assets do not include assets attributable to investments in other Nuveen funds or assets in excess of a determined amount (originally $2 billion) added to the Nuveen fund complex in connection with the Adviser’s assumption of the management of the former First American Funds effective January 1, 2011, but do include certain assets of certain Nuveen funds that were reorganized into funds advised by an affiliate of the Adviser during the 2019 calendar year. Eligible assets include closed-end fund assets managed by the Adviser that are attributable to certain types of leverage. For these purposes, leverage includes the closed-end funds’ use of preferred stock and borrowings and certain investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities, subject to an agreement by the Adviser as to certain funds to limit the amount of such assets for determining eligible assets in certain circumstances. As of March 31, 2021, the complex-level fee for each Fund was 0.1555%.

The Adviser has agreed to waive fees and/or reimburse expenses (“Expense Cap”) of the following Funds so that the total annual Fund operating expenses (excluding 12b-1 distribution and/or service fees, interest expenses, taxes, acquired fund fees and expenses, fees incurred in acquiring and disposing of portfolio securities and extraordinary expenses) do not exceed the average daily net assets of any class of Fund shares in the amounts and for the time periods stated in the following table. The expense limitations expiring July 31, 2022, may be terminated or modified prior to that date only with the approval of the Board.

Fund	Expense Cap	Expense Cap Expiration Date
Short Duration High Yield	0.65%	July 31, 2022
Strategic Municipal Opportunities	0.64	July 31, 2022

Distribution and Service Fees

Each Fund has adopted a distribution and service plan under rule 12b-1 under the 1940 Act. Class A Shares incur a 0.20% annual 12b-1 service fee. Class C Shares incur a 0.75% annual 12b-1 distribution fee and a 0.25% annual 12b-1 service fee. Class C2 Shares incur a 0.55% annual 12b-1 distribution fee and a 0.20% annual 12b-1 service fee. Class R6 and Class I Shares are not subject to 12b-1 distribution or service fees. The fees under this plan compensate Nuveen Securities, LLC, (the “Distributor”), a wholly-owned subsidiary of Nuveen, for services provided and expenses incurred in distributing shares of the Funds and establishing and maintaining shareholder accounts.

Corporate-Backed Municipal Bond: A municipal bond issued by a state or local government agency and backed by a corporate entity.

Effective Leverage (Effective Leverage Ratio): Effective leverage is investment exposure created either through borrowings or indirectly through inverse floaters, divided by the assets invested, including those assets that were purchased with the proceeds of the leverage, or referenced by the levered instrument. The calculation of the Effective Leverage Ratio reflects borrowings effected on a long-term basis for investment purposes, but excludes borrowings that may occur, on a transient basis, in connection with a Fund’s day-to-day operations primarily in connection with the need to pay cash out to redeeming shareholders or to settle portfolio trades.

Industrial Development Revenue Bond (IDR): A unique type of revenue bond issued by a state or local government agency on behalf of a private sector company and intended to build or acquire factories or other heavy equipment and tools.

Leverage: Leverage is created whenever a fund has investment exposure (both reward and/or risk) equivalent to more than 100% of the investment capital.

Lipper High Yield Municipal Debt Funds Classification Average: Represents the average annualized total return for all reporting funds in the Lipper High Yield Municipal Debt Funds Classification. Lipper returns account for the effects of management fees and assume reinvestment of distributions, but do not reflect any applicable sales charge.

S&P Municipal Yield Index: Comprises all of the bonds in the S&P Municipal Bond Index that are non-rated or rated BB+ by S&P and/or Ba1 or lower by Moody’s. The index does not contain bonds that are pre-refunded or escrowed to maturity. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.

S&P Short Duration Municipal Yield Index: An index that consists of bonds maturing in 1 to 12 years and is structured so that 70% of the market value of the index consists of bonds that are either non-rated or are rated below investment grade, and 20% are rated BBB/Baa, and 10% are rated single A. The index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.

Zero Coupon Bond: A zero coupon bond does not pay a regular interest coupon to its holders during the life of the bond. Income to the holder of the bond comes from accretion of the difference between the original purchase price of the bond at issuance and the par value of the bond at maturity and is effectively paid at maturity. The market prices of zero coupon bonds generally are more volatile than the market prices of bonds that pay interest periodically.

Annual Investment Management Agreement Approval Process

(Unaudited)

At a meeting held on May 19-21, 2020 (the “May Meeting”), the Board of Trustees (the “Board” and each Trustee, a “Board Member”) of the Funds, which is comprised entirely of Board Members who are not “interested persons” (as defined under the Investment Company Act of 1940 (the “1940 Act”)) (the “Independent Board Members”), approved, for each Fund, the renewal of the management agreement (each, an “Investment Management Agreement”) with Nuveen Fund Advisors, LLC (the “Adviser”) pursuant to which the Adviser serves as investment adviser to such Fund and the sub-advisory agreement (each, a “Sub-Advisory Agreement”) with Nuveen Asset Management, LLC (the “Sub-Adviser”) pursuant to which the Sub-Adviser serves as the investment sub-adviser to such Fund. Although the 1940 Act requires that continuances of the Advisory Agreements (as defined below) be approved by the in-person vote of a majority of the Independent Board Members, the May Meeting was held virtually through the internet in view of the health risks associated with holding an in-person meeting during the COVID-19 pandemic and governmental restrictions on gatherings. The May Meeting was held in reliance on an order issued by the Securities and Exchange Commission on March 13, 2020, as extended on March 25, 2020, which provided registered investment companies temporary relief from the in-person voting requirements of the 1940 Act with respect to the approval of a fund's advisory agreement in response to the challenges arising in connection with the COVID-19 pandemic.

•	Compliance Program Initiatives – continuing efforts to mitigate compliance risk, increase operating efficiencies, strengthen key compliance program elements and support international business growth and other objectives through, among other things, integrating various investment teams across affiliates, consolidating marketing review functions, enhancing compliance related technologies and establishing and maintaining shared broad-based compliance policies throughout the organization and its affiliates;

363

Table of Contents

Annual Investment Management Agreement Approval Process (Unaudited) (continued)

The Board’s determinations with respect to each Fund are summarized below.

For Nuveen High Yield Municipal Bond Fund, the Board noted that the Fund outperformed its benchmark and ranked in the first quartile of its Performance Peer Group for the one-, three- and five-year periods ended December 31, 2019. With the market decline in the first quarter of 2020, the Fund’s performance was below the performance of its benchmark for the one-, three- and five-year periods ended March 31, 2020. Although the Fund’s performance was ranked in the fourth quartile of its Performance Peer Group for the one-year period ended March 31, 2020, the Fund ranked in the first quartile of its Performance Peer Group for the three- and five-year periods ended March 31, 2020. Given the turmoil, rate volatility, and liquidity stresses experienced in the high yield municipals market as well as the outflows during the first quarter of 2020, the Board was satisfied with the Adviser’s explanation of the factors affecting the Fund’s performance.

For Nuveen Short Duration High Yield Municipal Bond Fund (the “Short Duration High Yield Fund”), the Board noted that the Fund outperformed its benchmark for the one-, three- and five-year periods ended December 31, 2019. Although the Fund ranked in the fourth quartile of its Performance Peer Group for the one-year period ended December 31, 2019, the Fund ranked in the third quartile of its Performance Peer Group for the three- and five-year periods ended December 31, 2019. With the market decline in the first quarter of 2020, the Fund’s performance was below the performance of its benchmark for the one-, three- and five-year periods ended March 31, 2020. Further, although the Fund ranked in the fourth quartile of its Performance Peer Group for the one-year period ended March 31, 2020, the Fund ranked in the second quartile of its Performance Peer Group for the three-year period ended March 31, 2020 and third quartile of its Performance Peer Group for the five-year period ended March 31, 2020. In its review, the Board noted, however, that the Performance Peer Group was classified as low for relevancy. Given the turmoil, rate volatility, and liquidity stresses experienced in the high yield municipals market as well as the outflows during the first quarter of 2020, the Board was satisfied with the Adviser’s explanation of the factors affecting the Fund’s performance.

For Nuveen Strategic Municipal Opportunities Fund (the “Strategic Fund”), the Board noted that the Fund outperformed its benchmark and ranked in the first quartile of its Performance Peer Group for the one-, three- and five-year periods ended December 31, 2019. With the market decline in the first quarter of 2020, the Fund’s performance was below the performance of its benchmark and the Fund ranked in the fourth quartile of its Performance Peer Group for the one-year period ended March 31, 2020, but the Fund outperformed its benchmark and ranked in the first quartile of its Performance Peer Group for the three- and five-year periods ended March 31, 2020. In its review, the Board noted that the Performance Peer Group was classified as low for relevancy. The Board was satisfied with the Fund’s overall performance.

C. Fees, Expenses and Profitability

1. Fees and Expenses

364

Table of Contents

The Independent Board Members reviewed the methodology Broadridge employed to establish its Peer Universe and Peer Group and recognized that differences between the applicable fund and its respective Peer Universe and/or Peer Group as well as changes to the composition of the Peer Group and/or Peer Universe from year to year may limit some of the value of the comparative data. The Independent Board Members also considered a fund’s operating expense ratio as it more directly reflected the shareholder’s costs in investing in the respective fund.

The Board noted that each Fund had a net management fee that was in line with the respective peer average and a net expense ratio that was below the respective peer average.

2. Comparisons with the Fees of Other Clients

In considering the fee data of other clients, the Board considered, among other things, the differences in the amount, type and level of services provided to the Nuveen funds relative to other clients as well as the differences in portfolio investment policies, investor profiles, account sizes and regulatory requirements, all of which contribute to the variations in the fee schedules. The Board recognized the complexity and myriad of services the Adviser had provided to the Nuveen funds compared to the other types of clients as the Adviser is principally responsible for all aspects of operating the funds, including complying with the increased regulatory requirements required when managing the funds as well as the increased entrepreneurial, legal and regulatory risks that the Adviser incurs in sponsoring and managing the funds. Further, with respect to ETFs, the Board considered that Nuveen ETFs are passively managed compared to the active management of the other Nuveen funds which contributed to the differences in fee levels between the Nuveen ETFs and other Nuveen funds. In general, higher fee levels reflect higher levels of service provided by the Adviser, increased investment management complexity, greater product management requirements, and higher levels of business risk or some combination of these factors. The Board further considered that the Sub-Adviser’s fee is essentially for portfolio management services and therefore more comparable to the fees it receives for retail wrap accounts and other external sub-advisory mandates. The Board concluded the varying levels of fees were justified given, among other things, the inherent differences in the products and the level of services provided to the Nuveen funds versus other clients, the differing regulatory requirements and legal liabilities and the entrepreneurial, legal and regulatory risks incurred in sponsoring and advising a registered investment company.

3. Profitability of Fund Advisers

365

adjusted margins of certain peers with publicly available data and with the most comparable assets under management (based on asset size and asset composition) for each of the last two calendar years. The Board also reviewed the revenues and expenses the Adviser derived from its ETF product line for the 2018 and 2019 calendar years.

D. Economies of Scale and Whether Fee Levels Reflect These Economies of Scale

366

Table of Contents

gible to be included in the calculation of the complex-wide fee when these Nuveen funds left the complex upon acquisition, Nuveen agreed to credit approximately $460 million to assets under management to the Nuveen complex in calculating the complex-wide component.

In addition to the fund-level and complex-level fee schedules, the Independent Board Members considered the temporary and/or permanent expense caps applicable to certain Nuveen funds (including the amounts of fees waived or amounts reimbursed to the respective funds in 2018 and 2019), including the temporary expense caps applicable to the Short Duration High Yield Fund and the Strategic Fund.

Based on its review, the Board concluded that the current fee arrangements together with the Adviser’s reinvestment in its business appropriately shared any economies of scale with shareholders.

E. Indirect Benefits

Based on its review, the Board concluded that any indirect benefits received by a Fund Adviser as a result of its relationship with the Funds were reasonable and within acceptable parameters.

F. Other Considerations
