Chair’s Letter to Shareholders
Dear Shareholders,
The COVID-19 crisis is taking an unprecedented toll on our health, societies, economies and financial markets. Our thoughts are with all whose lives have been affected by the disease and its economic fallout. The extreme “social distancing” efforts needed to contain the coronavirus are causing a severe contraction in economic activity and amplifying market volatility, as global supply chains and consumer and business demand have been significantly disrupted. With some regions of the world having appeared to “flatten the curve” of infections, governments and public health officials face the extraordinary challenge of balancing the resumption of economic activity with public safety, in a way that minimizes the potential for a second wave of outbreaks. The spike in market volatility during March and the strong rally that followed in April may be indicative of the large swings in both directions that are likely to continue as markets digest new information and seek more clarity.
While we do not want to understate the dampening effect on the global economy, it is important to differentiate short-term interruptions from the longer-lasting implications to the economy. Some areas of the global economy were already on the mend prior to the coronavirus epidemic. Momentum could pick up again as factories come back online and consumer demand resumes once the virus is under control and temporary bans on movement and travel are lifted. Central banks and governments around the world have announced economic stimulus measures. In the U.S., the Federal Reserve has cut its benchmark interest rate to near zero and introduced programs that helped revive the U.S. economy after the 2008 financial crisis. The U.S. Government has approved three relief packages, including a $2 trillion-dollar package directly supporting businesses and individuals. The Coronavirus Aid, Relief and Economic Security Act, called the CARES Act, provides direct payments and expanded unemployment benefits to individuals, loans and grants to small businesses, loans and other money to large corporations and funding for hospitals, public health, education and state and local governments. Additional aid will likely be approved in the months ahead.
In the meantime, patience and a long-term perspective are key for investors. When market fluctuations are the leading headlines day after day, it’s tempting to “do something.” However, your long-term goals can’t be met with short-term thinking. We encourage you to talk to your financial advisor, who can review your time horizon, risk tolerance and investment goals. On behalf of the other members of the Nuveen Fund Board, we look forward to continuing to earn your trust in the months and years ahead.
Sincerely,
Terence J. Toth

Recently, the portfolio managers reviewed economic and market conditions, key investment strategies, and the Funds’ performance for the twelve-month reporting period ended March 31, 2020.
What factors affected the U.S. economy and the national municipal bond market during the twelve-month reporting period ended March 31, 2020?
The longest economic expansion in U.S. history came to an abrupt halt in early 2020 amid the COVID-19 coronavirus pandemic. To slow the spread of the virus, large portions of the economy were shut down, with companies closing either temporarily or permanently and most of the U.S. population under stay-at-home orders (as of the end of March 2020). The disruption has been swift and severe, and is expected to tip the economy into recession, a several months’ long contraction across the broad economy. For the first quarter of 2020, the Bureau of Economic Analysis reported that annualized gross domestic product (GDP) shrank 4.8%, according to its “advance” estimate. GDP measures the value of goods and services produced by the nation’s economy less the value of the goods and services used up in production, adjusted for price changes. Previously, the economy had been expanding at a moderate clip. GDP grew at an annualized rate of 2.1% in the fourth quarter of 2019 and grew 2.3% in 2019 overall.
Consumer spending, the largest driver of the economy, was well supported earlier in this reporting period by low unemployment, wage gains and tax cuts. However, the COVID-19 containment measures drove a significant drop in consumer spending and a sharp rise in unemployment in the final month of the quarter. The Bureau of Labor Statistics said the unemployment rate rose to 4.4% in March 2020 from 3.8% in March 2019 and job gains averaged around 118,000 per month for the past twelve months, as the economy lost 701,000 jobs in March 2020. Average hourly earnings grew at an annualized rate of 3.1% in March 2020. However, the overall trend of inflation remained subdued, and registered a notably slower rate in March 2020 due to falling gasoline prices. The Bureau of Labor Statistics said the Consumer Price Index (CPI) increased 1.5% over the twelve-month reporting period ended March 31, 2020 before seasonal adjustment.

Portfolio Managers’ Comments(continued)
Low mortgage rates and low inventory drove home prices moderately higher in this reporting period, although the most recent data do not yet reflect the shutdown. The S&P CoreLogic Case-Shiller U.S. National Home Price Index, which covers all nine U.S. census divisions, was up 4.2% year-over-year in February 2020 (most recent data available at the time this report was prepared). The 10-City and 20-City Composites reported year-over-year increases of 2.9% and 3.5%, respectively.
With economic momentum slowing in 2019 from 2018’s stronger pace, the U.S. Federal Reserve (Fed) left rates unchanged throughout the first half of 2019 then cut rates by 0.25% at each of the July 2019, September 2019 and October 2019 policy committee meetings. Markets registered disappointment with the Fed’s explanation that the rate cuts were a “mid-cycle adjustment,” rather than a prolonged easing period, and its signal that there would be no additional rate cuts in 2019. Also in the latter half of 2019, the Fed announced it would stop shrinking its bond portfolio sooner than scheduled, as well as began buying short-term Treasury bills to help money markets operate smoothly and maintain short-term borrowing rates at low levels. Fed Chairman Powell emphasized that the Treasury bill purchases were not a form of quantitative easing. The Fed continued its Treasury bill buying in January 2020, as well as left its benchmark interest rate unchanged, while noting the emerging coronavirus risks. As the outbreak spread to the U.S. and significant restrictions on social and economic activity were imposed starting in March 2020, the Fed enacted an array of emergency measures to stabilize the financial system and support the markets, including cutting its main interest rate to near zero, offering lending programs to aid small and large companies and allowing unlimited bond purchases, known as quantitative easing. Meanwhile, the U.S. government approved three aid packages, totaling more than $100 billion in funding to health agencies and employers offering paid leave and $2 trillion allocated across direct payments to Americans, an expansion of unemployment insurance, loans to large and small businesses, funding to hospitals and health agencies and support to state and local governments.
While trade and tariff policy drove market sentiment for most of the twelve-month reporting period, the outbreak of the novel coronavirus and its associated disease COVID-19 rapidly dwarfed all other market concerns as the reporting period was closing. Equity and commodity markets sold-off and safe-haven assets rallied as China, other countries and then the United States initiated quarantines, restricted travel and shuttered factories and businesses. The potential economic shock was particularly difficult to assess, which amplified market volatility.
Prior to the virus outbreak, global markets had become more bullish on the outlook for 2020 as trade policy and Brexit appeared to make progress at the end of 2019. The U.S. and China agreed on a partial trade deal, which included rolling back some tariffs, increasing China’s purchases of U.S. agriculture products and the consideration of intellectual property, technology and financial services rights. The “phase one” deal was signed on January 15, 2020. While much of the focus remained on the U.S.-China relationship, trade spats between the U.S. and Mexico, the European Union (EU), Brazil and Argentina also arose throughout the reporting period. In January 2020, the U.S. Congress fully approved the U.S., Mexico and Canada Agreement (USMCA), which replaces the North American Free Trade Agreement. With more clarity on trade deals, the trade-related deterioration in global manufacturing and export data was expected to improve. However, the COVID-19 crisis has since upended those assumptions.
Investors also remained watchful of local political dynamics around the world. In the U.K., the Conservative Party won a large majority in the December 2019 general election and Parliament passed the Brexit Bill days later, facilitating the U.K.’s exit from the EU at the end of January 2020. In Italy, the prime minister unexpectedly resigned in August 2019, and the newly formed coalition government appeared to take a less antagonistic stance towards the EU. Europe’s traditional centrist parties lost seats in the May 2019 Parliamentary elections and populist parties saw marginal gains. Europe also contended with the “yellow vest” protests in France, immigration policy concerns, Russian sanctions and political risk in Turkey. Anti-government protests erupted across Latin America, Hong Kong and Lebanon during 2019. Venezuela’s economic and political crisis deepened. Argentina surprised the market with the return of a less market-friendly administration. Brazil’s Bolsonaro administration achieved a legislative win on pension reform and kept the economy on a path of modest growth. The ruling parties in India and South Africa maintained their majorities, where slower economic growth could complicate their respective reform mandates.
Despite the severe sell-off in March 2020, municipal bonds managed positive performance over the twelve-month reporting period. For most of the reporting period, a significant decline in interest rates drove municipal bond prices higher, with positive technical and fundamental conditions also supporting credit spread tightening. Prior to the emergence of the novel coronavirus, interest rates had been pressured lower by signs that the economy’s momentum was slowing, a more dovish central bank policy, geopolitical tensions (especially regarding trade) and bouts of equity market volatility. Then, from late February through March 2020, COVID-19 risks per-
meated the markets, sending U.S. Treasury yields to historic lows. Rate volatility increased sharply in that six-week period. As liquidity became stressed, investors began to liquidate any asset possible, including municipal bonds. Municipal bond prices declined rapidly, amid rampant selling across both the high grade and high yield segments that was exacerbated in some cases by exchange-traded fund and closed-end fund selling. Credit spreads widened significantly during the March 2020 sell-off, ending the month above their long-term average. In the final weeks of the reporting period, monetary and fiscal interventions from the Fed and U.S. government helped the market stabilize, although prices remained meaningfully off their pre-crisis levels. The U.S. Treasury yield curve flattened overall, with a portion of the curve temporarily inverting from late August 2019 to late September 2019. The municipal yield curve also flattened overall, as yields on longer maturities fell more than those of shorter maturities.
Prior to the market turmoil in March 2020, municipal bond gross issuance nationwide had been robust. The overall low level of interest rates encouraged issuers to continue to actively refund their outstanding debt. In these transactions the issuers are issuing new bonds and taking the bond proceeds and redeeming (calling) old bonds. These refunding transactions have ranged from 30% to 60% of total issuance over the past few years. Thus, the net issuance (all bonds issued less bonds redeemed) is actually much lower than the gross issuance. So, while gross issuance volume has been adequate, the net has not and this was an overall positive technical factor on municipal bond investment performance in recent years.
Demand for municipal bonds was strong for most of this reporting period. Municipal bond funds took in consistently positive cash flows in calendar year 2019 and the first two months of 2020. However, fund flows turned more volatile in March 2020, as markets began to digest the COVID-19 impact. Low interest rates in the U.S. and globally have continued to drive investors toward higher after-tax yielding assets, including U.S. municipal bonds. Additionally, as tax payers have begun to assess the impact of the 2017 tax law, which caps the state and local tax (SALT) deduction for individuals, there has been increased demand for tax-exempt municipal bonds in 2019 to date, especially in states with high income taxes and/or property taxes.
How did the Funds perform during the twelve-month reporting period ended March 31, 2020?
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 the one-year, five-year and ten-year and/or since-inception periods ended March 31, 2020. 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 underperformed their respective benchmark indexes. The Nuveen Intermediate Duration Municipal Bond Fund outperformed its Lipper classification average, while the other three Funds lagged this performance comparison to varying degrees.
What key strategies were used to manage these Funds during the twelve-month reporting period, and how did these strategies influence performance?
Nuveen All-American Municipal Bond Fund, Nuveen Intermediate Duration Municipal Bond Fund and Nuveen Limited Term Municipal Bond Fund’s investment objective 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.
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 All-American Municipal Bond Fund
The Nuveen All-American Municipal Bond Fund’s Class A Shares at NAV underperformed the S&P Municipal Bond Index for the twelve-month reporting period ended March 31, 2020. During the reporting period, the performance of the Fund was negatively impacted by the COVID-19 Coronavirus. Prices of portfolio securities generally fell and, as was the case of mutual funds generally, the Fund specifically experienced net redemptions of shares, and sold portfolio assets to raise the cash to pay those redemptions.
Portfolio Managers’ Comments(continued)
Municipal bonds were hit especially hard as investors withdrew money from the asset class at a record pace. The Fund, too, experienced significant shareholder withdrawals, forcing us to sell certain holdings to raise cash to meet redemptions. In making these sales, we worked to be as efficient as possible. This entailed identifying bonds with certain desirable structures or levels of credit quality and, because they were benefiting from stronger demand from banks and other investors, were thus seeing comparatively firm prices. Notable such sales included higher coupon, high quality securities of Douglas County School District, certain bonds backed by New York City and debt issued by Syracuse University. In the difficult market environment, these sales typically took place at a loss, given that municipal bond prices were under pressure at the time.
The Fund’s credit quality positioning further hurt performance. Throughout the reporting period, we remained overweighted in bonds with lower investment grade and below investment grade credit ratings. Our bias toward these higher yielding bonds added value from the beginning of the reporting period through February 2020, given that these securities generally outpaced lower yielding, higher quality securities. However, this same positioning significantly hurt the Fund in March 2020, when investors’ acute aversion to risk caused lower quality securities to suffer especially steep price declines.
Among the Fund’s lower quality holdings, airport and other transportation bonds were under particular strain. We saw significant losses from some of our larger holdings in the sector, led by California Municipal Finance Authority bonds of the LINXS public transportation project at Los Angeles International Airport and bonds issued for Virgin Trains USA Passenger Rail Project, a privately operated South Florida rail line, which was forced to temporarily shut down in response to the COVID-19 crisis.
The Fund’s security selection detracted from relative performance. We saw weak results from holdings backed by economically sensitive sales taxes, including the Metropolitan Pier and Exposition Authority (Chicago) and the American Dream megamall (New Jersey), both of which closed their sites to combat the spread of the COVID-19 crisis. Sales-tax-backed bonds from Puerto Rico (commonly known as COFINAs) also performed poorly. (Bonds of Puerto Rico and other U.S. territories may include exemption from most federal, state and local taxes.)
Other issuers that entered March 2020 facing persistent credit concerns produced large losses during the end of the reporting period market sell-off. Our holdings in Buckeye Tobacco Settlement Financing Authority performed poorly amid concerns about the issuer’s ability to complete a needed restructuring. Another poor performer was the Chicago Board of Education, whose bonds struggled as the issuer faced ongoing concern about its ability to meet its pension funding obligations.
The Fund’s duration (interest rate) positioning contributed to performance. Because the portfolio’s duration was longer than that of the benchmark, the Fund benefited more fully as interest rates declined for the reporting period. Moderately tempering that positive result, however, was our use of U.S. Treasury futures contracts to hedge against potential inflation. These futures lagged as inflation remained muted. Our use of certain floating rate securities, including tender option bonds (TOBs) and variable rate demand notes (VRDNs) also modestly boosted the Fund’s relative performance.
As the municipal market sold off toward the end of the reporting period, we found opportunities to purchase bonds we liked at attractive valuations, while we remained careful about how the COVID-19 crisis could affect the financial position of issuers. We used modest shareholder inflows in the reporting period’s final week to add to the Fund’s existing positions in COFINA, Buckeye Tobacco and certain transportation and hospital bonds.
Additionally, the end of the reporting period environment was favorable for executing tax-loss swaps. This entailed selling depreciated bonds with lower yields and buying similarly structured bonds offering higher yields. We implemented this approach to enhance the Fund’s income earnings capability and seek to make the Fund more tax efficient.
Nuveen Intermediate Duration Municipal Bond Fund
The Nuveen Intermediate Duration Municipal Bond Fund’s Class A Shares at NAV underperformed the S&P Municipal Bond Intermediate Index for the twelve-month reporting period ended March 31, 2020. During the reporting period, the performance of the Fund was negatively impacted by the COVID-19 Coronavirus. Prices of portfolio securities generally fell and, as was the case of mutual funds generally, the Fund specifically experienced net redemptions of shares, and sold portfolio assets to raise the cash to pay those redemptions.
Relative to the index, credit quality positioning was the main driver of the Fund’s relative performance shortfall. Coming into the reporting period, we were anticipating continued decent economic growth, low inflation and solid and improving credit fundamentals. This was what we encountered for roughly the first eleven months of the reporting period and our credit positioning added value during that time.
Conditions changed markedly in the last month of this reporting period, however, as the economic shutdown following the spread of the COVID-19 reversed most of the market’s once-positive fundamentals. In March 2020, our elevated exposure to bonds on the lower end of the credit spectrum and reduced weighting in higher quality issues proved detrimental for the Fund’s relative performance.
Meanwhile, the Fund’s individual security selection also detracted from performance, led by various lower rated holdings. The Fund’s sizable allocation to poor performing Illinois state debt proved detrimental, as did our exposure to non-rated Virgin Trains USA Passenger Rail Project, a privately operated South Florida rail line, which was forced to temporarily shut down in response to the COVID-19 crisis, weighed on the Fund's performance. Other notable individual underperformers in the Fund included New York City Metropolitan Transportation Authority bonds, which struggled as the usage of public transportation essentially disappeared during the city’s economic shutdown, and various lower rated bonds affiliated with Puerto Rico, whose credit risk proved unattractive to investors during the market’s volatile final month of the reporting period.
The Fund’s duration (interest rate) positioning added value. Despite a brief spike in interest rates during March 2020, rates ultimately reversed that increase in the final two weeks of the reporting period and finished lower overall for the twelve-month reporting period. This positioning contributed to the Fund’s result, given that the portfolio’s duration was longer than the index, meaning we were positioned to capture more of the beneficial effects of declining rates.
Also contributing to relative performance was our overweighting in pre-refunded bonds, which, owing to their very high credit quality and limited duration risk, allowed them to outperform. In addition, an allocation to single-family housing bonds added value, given that category’s favorable results.
For most of this reporting period, our constructive economic outlook frequently led us to favor bonds with slightly longer durations and more credit risk than the overall market. Over time, however, our investment focus gradually shifted toward higher quality issues, reflecting our view that these securities, especially in shorter and intermediate segments of the yield curve, were starting to offer better risk/reward trade-offs as credit spreads narrowed. Still, we were pleased that we were able to essentially maintain the existing credit risk profile of the Fund, which we found generally well positioned.
In March 2020, as the municipal bond market sold off dramatically, the Fund experienced significant investment outflows. To satisfy these shareholder redemptions, we were actively selling bonds in as efficient a manner as we could. Our approach to these sales was to remain patient and diligent as we pursued attractive bids for those bonds we wished to liquidate. The securities we did sell tended to be relatively higher in quality and shorter in duration, as these characteristics were more in demand amid the market’s elevated volatility. We also opted to maintain various portfolio holdings that, despite their large price declines, we believed were likely to rebound over time.
Although our transaction activity during March 2020 was far more geared toward selling than buying bonds, we did periodically take advantage of opportunities to purchase bonds we found attractively priced and presented our shareholders with attractive long-term value.
Portfolio Managers’ Comments(continued)
Nuveen Limited Term Municipal Bond Fund
The Nuveen Limited Term Municipal Bond Fund’s Class A Shares at NAV underperformed the S&P Municipal Bond Short-Intermediate Index for the twelve-month reporting period ended March 31, 2020. During the reporting period, the performance of the Fund was negatively impacted by the COVID-19 Coronavirus. Prices of portfolio securities generally fell and, as was the case of mutual funds generally, the Fund specifically experienced net redemptions of shares, and sold portfolio assets to raise the cash to pay those redemptions.
The Fund’s credit quality allocation was the main detractor from performance relative to the index. Although our emphasis of bonds with lower credit ratings and corresponding underweighting in higher rated bonds added value for much of the reporting period, this positioning was meaningfully negative in March 2020, when the municipal bond market sharply fell. Unfortunately, this significant underperformance more than offset the positive impact seen in the prior eleven months of the reporting period.
Another negative performance factor was individual security selection, with some of our lower rated positions particularly detracting from relative performance. The Fund had a relatively large position in Illinois state bonds, which lagged, as well as the Fund’s allocation to non-rated bonds of Virgin Trains USA Passenger Rail Project, a privately operated South Florida rail line project. In March 2020, Virgin Trains temporarily suspended operations in response to the COVID-19 crisis. Other underperformers included New York City Metropolitan Transportation Authority bonds, which declined in value as social distancing resulted in dramatically lower ridership of the city’s public transportation, as well as lower rated bonds affiliated with Puerto Rico.
The Fund benefited from its duration, or interest rate, positioning. On balance, rates declined during the twelve-month reporting period, which proved helpful for our relative performance. Because the Fund’s duration was longer than that of the index, we benefited to a greater extent from the decline in rates.
Also modestly adding to the Fund’s relative performance, was the Fund's overweight in hospital debt as these bonds slightly outperformed the market during the reporting period. Exposure to single-family housing bonds also contributed to performance, as these credits fared relatively well.
For much of the reporting period, we were favoring bonds that provided more credit risk than the overall market. As the reporting period progressed, however, we increasingly shifted our emphasis to bonds of higher credit quality. This gradually increasing preference reflected our opinion that as credit spreads narrowed (meaning that investors were willing to accept steadily less income in exchange for credit risk), higher rated bonds were beginning to offer better risk-adjusted value. Even with this shift in emphasis when purchasing new bonds, we were successful in maintaining the Fund’s underlying credit risk profile, which we found attractive coming into the reporting period.
In March 2020, our investment focus shifted to reflect the dramatically changed market conditions. The Fund, like most other municipal bond funds, saw investment outflows during March 2020 as the market environment weakened. To generate the proceeds needed to fund these outflows, we were frequently selling bonds benefiting from stronger demand and thus seeing attractive bids from buyers. Our bond sales focused on higher quality, shorter-duration issues, given the market’s higher demand for such securities. We also maintained various portfolio positions we believed remained solid long-term holdings and were likely candidates for a recovery in their valuations. While in March 2020 we were more actively selling than buying bonds, we also periodically bought bonds we saw as attractively priced relative to their credit risk.
Nuveen Short Term Municipal Bond Fund
The Nuveen Short Term Municipal Bond Fund’s Class A Shares at NAV underperformed the S&P Municipal Bond Short Index for the twelve-month reporting period ended March 31, 2020. The performance of the Fund was negatively impacted late in the reporting period by the COVID-19 Coronavirus. Credit spreads widened and prices of portfolio securities generally fell in March 2020, although the Fund was one of few to experience net inflows for the month.
The Fund outperformed the index throughout much of the reporting period due to advantageous sector, credit quality and duration positioning. However, some of these same factors proved disadvantageous during the historic municipal bond market sell-off in March 2020, causing the portfolio to lag the benchmark for the reporting period overall.
The Fund’s sector positioning with overweightings in health care (predominantly hospitals and to a small extent senior living), transportation, and bank-backed gas-prepay bond segments initially boosted relative performance. From the beginning of the reporting period through the end of February 2020, bonds in these categories generally outpaced the index, bolstered by their higher yields and investors’ appetite for such securities. In March 2020, however, these same sectors were considered more vulnerable to the shutdown of the economy amid the spread of the COVID-19. These sectors underperformed in response to the pandemic and ultimately, in some cases, detracted from the Fund’s relative performance for the reporting period.
The Fund experienced a similar trend from the perspective of the Fund’s overall credit quality positioning. The Fund’s exposure to lower quality investment grade securities (rated A and BBB) and non-investment grade securities (rated BB) was helpful until March 2020, as credit spreads generally narrowed and lower rated bond categories outperformed their higher rated counterparts. Similar to sector weightings, though, this same positioning proved unfavorable in March 2020, generally negating the relative benefit it had previously provided. As credit spreads widened substantially during the reporting period’s final month in March 2020 (indicating that investors were demanding more income from lower quality bonds as compensation for the securities’ higher credit risk), lower rated bonds suffered greater price losses, weighing on the Fund’s results.
From a duration (interest rate) standpoint, the Fund was longer than the benchmark going into the March 2020 market downturn. This stance had been beneficial, given that interest rates had generally been falling over the period. As yields rose throughout the curve in early March 2020, the stress in the financial markets prompted investors to rotate into more defensive assets, including shorter-term bonds. Unlike the experience of many longer maturity funds, this phenomenon drove a sharp increase of shareholder flows into the Fund starting in mid-month March 2020. While we did take advantage of these investment inflows and market price dislocations to buy bonds, the magnitude of the inflows actually proved mildly disadvantageous (from a relative performance standpoint). The cash inflows mildly shortened the Fund’s duration somewhat (despite the Fund’s buying program), and the high grade market subsequently mounted a partial rally toward the very end of the reporting period.
The portfolio’s sector allocations and credit quality positioning remained generally consistent throughout the reporting period. Our late March 2020 purchases found many bonds with attractive yield opportunities and we decided to focus primarily on higher grade credit tiers with good liquidity. The purchases still targeted the Fund’s customary maturity range of approximately 0-5 years, but for now concentrated more heavily on tax-backed and essential service revenue bond sectors.
Risk Considerations and Dividend Information
Risk Considerations
Nuveen All-American 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, 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. Below investment grade or high yield debt securities are subject to liquidity risk and heightened credit risk. In addition, the Fund periodically engages in a moderate 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.

Dividend Information
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.
All monthly dividends paid by each 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 each Fund’s distributions for the reporting period are presented in this report’s Financial Highlights. For income tax purposes, distribution information for each 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.

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.
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 8—Borrowing Arrangements, are excluded from the calculation of a Fund’s effective leverage ratio.

The graphs do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or the redemption of Fund shares.
Yields as of March 31, 2020
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.

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.

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, 2020.
The beginning of the period is October 1, 2019.
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.

Opinions on the Financial Statements
We have audited the accompanying statements of assets and liabilities, including the portfolios of investments, of Nuveen All-American Municipal Bond Fund, Nuveen Intermediate Duration Municipal Bond Fund and Nuveen Limited Term Municipal Bond Fund (three of the funds constituting Nuveen Municipal Trust) and Nuveen Short Term Municipal Bond Fund (one of the funds constituting Nuveen Investment Funds, Inc.) (hereafter collectively referred to as the "Funds") as of March 31, 2020, the related statements of operations for the year ended March 31, 2020, the statements of changes in net assets for each of the two years in the period ended March 31, 2020, 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, 2020, 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, 2020 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, 2020 by correspondence with the custodians 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.

Notes to Financial Statements
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, 2020, and the period covered by these Notes to Financial Statements is the fiscal year ended March 31, 2020 (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 $250,000 or more 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% (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 ten years 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 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. There have been no comparable recent events that provide guidance as to the effect the spread of COVID-19 as a global pandemic may have on the Funds' financial performance. 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 Funds' Board of Directors/Trustees (the "Board") has adopted a deferred compensation plan for independent directors 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. Dividend income 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 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.
New Accounting Pronouncements and Rule Issuances
FASB Accounting Standards Update (“ASU”) 2017-08 (“ASU 2017-08”) Premium Amortization on Purchased Callable Debt Securities
The FASB has issued ASU 2017-08, which shortens the premium amortization period for purchased non-contingently callable debt securities. ASU 2017-08 specifies that the premium amortization period ends at the earliest call date, for purchased non-contingently callable debt securities. ASU 2017-08 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. During the current fiscal period, ASU 2017-08 became effective for the Fund and it did not have a material impact on the Fund's financial statements.
Fair Value Measurement: Disclosure Framework
During August 2018, the FASB issued ASU 2018-13 (“ASU 2018-13”), Fair Value Measurement: Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurements. ASU 2018-13 modifies the disclosures required by Topic 820, Fair Value Measurements. The amendments in ASU 2018-13 are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Management has early implemented this guidance and it did not have a material impact on the Fund's financial statements.
Notes to Financial Statements(continued)
Reference Rate Reform
In March 2020, FASB issued 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 at the end of 2021, 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. In addition, derivative contracts that qualified for hedge accounting prior to modification, will be allowed to continue to receive such treatment, even if critical terms change due to a change in the benchmark interest rate. For new and existing contracts, the Funds may elect to apply the amendments as of March 12, 2020 through December 31, 2022. Management is currently assessing the impact of the ASU’s adoption to the Funds’ financial statements and various filings.
3. Investment Valuation and Fair Value Measurements
The fair valuation input levels as described below are for fair value measurement purposes.
The Funds' investments in securities are recorded at their estimated fair value. 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. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The following is a summary of the three-tiered hierarchy of valuation input levels.
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).
Common stocks and other equity-type securities are valued at the last sales price on the securities exchange on which such securities are primarily traded and are generally classified as Level 1. Securities primarily traded on the Nasdaq National Market (“Nasdaq”) are valued at the Nasdaq Official Closing Price and are generally classified as Level 1. However, securities traded on a securities exchange or Nasdaq for which there were no transactions on a given day or securities not listed on a securities exchange or Nasdaq are valued at the quoted bid price and are generally classified as Level 2.
Prices of fixed-income securities are 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. These securities are generally classified as Level 2. In pricing certain securities, particularly less liquid and lower quality securities, the pricing service may consider information about a security, its issuer or market activity, provided by the Adviser. These securities are generally classified as Level 2 or Level 3 depending on the observability of the significant inputs.
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.
Certain securities may not be able to be priced by the pre-established pricing methods as described above. Such securities may be valued by the Board and/or its appointee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; debt securities that have gone into default and for which there is no current market quotation; a security whose market price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund’s NAV (as may be the case in non-U.S. markets on which the security is primarily traded) or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, is not deemed to reflect the security’s fair value. As a general principle, the fair value of a security would appear to be the amount that the owner might reasonably expect to receive for it in a current sale. A variety of factors may be considered in determining the fair value of such securities, which may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. These securities are generally classified as Level 2 or Level 3 depending on the observability of the significant inputs. Regardless of the method employed to value a particular security, all valuations are subject to review by the Board and/or its appointee.
The inputs or methodologies used for valuing securities are not an indication of the risks associated with investing in those securities. The following is a summary of each Fund’s fair value measurements as of the end of the reporting period:

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-
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 | $63,845,000 | $ — | $ — | $ — |
| Floating rate obligations: externally-deposited Inverse Floaters | 8,370,000 | 12,490,000 | — | — |
| Total | $72,215,000 | $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 |

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.
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, each Fund’s 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 | $63,845,000 | $ — | $ — | $ — |
| Maximum exposure to Recourse Trusts: externally-deposited Inverse Floaters | 8,370,000 | 12,490,000 | — | — |
| Total | $72,215,000 | $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 | $2,260,154,992 | $3,866,396,972 | $1,838,706,903 | $250,955,158 |
| Sales and maturities | 707,054,700 | 1,797,710,512 | 1,206,434,189 | 216,911,382 |
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
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-
Notes to Financial Statements(continued)
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* | $31,368,493 |
| * | The average notional amount is calculated based on the absolute aggregate notional of contracts outstanding 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 futures 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.

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.
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, 2020.
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 | $5,319,860,244 | $8,574,750,908 | $5,845,943,495 | $680,577,283 |

| Depreciation | (83,779,119) | (103,106,719) | (60,507,333) | (3,776,789) |
| Net unrealized appreciation (depreciation) of investments | $158,816,692 | $183,874,686 | $43,118,762 | $510,657 |
Permanent differences, primarily due to federal taxes paid and taxable market discount, resulted in reclassifications among the Funds’ components of net assets as of March 31, 2020, 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, 2020, the Funds’ tax year end, were as follows:
| | All-American | Intermediate
Duration | Limited Term | Short Term |
| Undistributed net tax-exempt income1 | $6,033,841 | $22,442,224 | $21,342,073 | $2,944,694 |
| Undistributed net ordinary income2 | 1,049,408 | 2,066,465 | 1,598,803 | 1,337 |
| 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, 2020 through March 31, 2020, and paid on April 1, 2020. |
| 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, 2020 and March 31, 2019 was designated for purposes of the dividends paid deduction as follows:
| 2020 | All-American | Intermediate

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 |
* 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, 2020, the complex-level fee for each Fund was as follows:
| Fund | Complex-Level Fee |
| All-American | 0.1620% |
| Intermediate Duration | 0.1622% |
| Limited Term | 0.1590% |
| Short Term | 0.1750% |
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.
| Fund | Temporary
Expense Cap | Temporary
Expense Cap
Expiration Date | Permanent
Expense Cap |
| Intermediate Duration | N/A | N/A | 0.75% |
N/A - Not applicable.
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 other accounts managed by the Sub-Adviser (“inter-fund trade”) under specified conditions outlined in procedures adopted by the Board. These procedures have been designed to ensure that any inter-fund trade of securities by the Fund from or to another fund that is, or could be, considered an affiliate of the Fund under certain limited circumstances 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. Further, as defined under these procedures, each inter-fund trade is effected at the current market price as provided by an independent pricing service. Unsettled inter-fund trades as of the end of the reporting period are recognized as a component of “Receivable for investments sold” and/or “Payable for investments purchased” on the Statement of Assets and Liabilities, when applicable.

Duration | Limited Term | Short Term |
| Commission advances (Unaudited) | $8,428,944 | $2,037,418 | $1,735,186 | $323,583 |
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) | $523,052 | $135,309 | $108,021 | $3,866 |

Duration | Limited Term | Short Term |
| CDSC retained (Unaudited) | $403,140 | $144,251 | $228,839 | $129,096 |
8. Borrowing Arrangements
Committed Line of Credit
The Funds, along with certain other funds managed by the Adviser (“Participating Funds”), have established a 364-day, $2.65 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 2020 unless extended or renewed.
The credit facility has the following terms: a fee of 0.15% per annum on unused commitment amounts, and interest at a rate equal to the higher of (a) one-month LIBOR (London Inter-Bank Offered Rate) plus 1.00% per annum or (b) the Fed Funds rate plus 1.00% per annum on amounts borrowed. 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 a follows:
| | All-
American | Intermediate
Duration | Limited
Term |
| Maximum outstanding balance | $47,500,000 | $180,600,000 | $93,000,000 |
During the 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:
| | All-
American | Intermediate
Duration | Limited
Term |
| Utilization period (days outstanding) | 51 | 11 | 54 |
| Average daily balance outstanding | $13,425,490 | $126,636,364 | $29,724,074 |
| Average annual interest rate | 2.97% | 2.03% | 3.02% |
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.
9. Subsequent Events
Fund Mergers
During May 2020, the Board approved the merger of Nuveen Tennessee Municipal Bond Fund (the "Target Fund") into All-American (the "Acquiring Fund") (the "Reorganization"). In order for the Reorganization to occur, it must be approved by shareholders of the Target Fund.
Upon the closing of the Reorganization, the Target Fund will transfer 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 will then be liquidated, dissolved and terminated in accordance with its Declaration of Trust. Shareholders of its Target Fund will become shareholders of the Acquiring Fund. Each Target Fund shareholder will receive shares of the Acquiring Fund, the aggregate 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).

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.
Glossary of Terms Used in this Report(Unaudited) (continued)
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.
Lipper Short-Intermediate Municipal Debt Funds Classification Average:Represents the average annualized total return for all reporting funds in the Lipper Short-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.
Lipper Short Municipal Debt Funds Classification Average:Represents the average annualized total return for all reporting funds in the Lipper Short 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 charges.
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-Refunding, also known as advanced refundings or refinancings, is a procedure used by state and local governments to refinance municipal bonds to lower interest expenses. The issuer sells new bonds with a lower yield and uses the proceeds to buy U.S. Treasury securities, the interest from which is used to make payments on the higher-yielding bonds. Because of this collateral, pre-refunding generally raises a bond’s credit rating and thus its value.
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. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.
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.
Weighted Average Portfolio Duration:The weighted average duration, including the effects of leverage, of a fund’s bonds and loans, which is a measure of the fund’s price sensitivity expressed in years.
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 21-23, 2019 (the “May Meeting”), the Board of Trustees or Directors, as applicable (the “Board” and each Trustee or Director, a “Board Member”) of the Funds, including the 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 sub-adviser to such Fund. Following an initial two-year period, the Board, including the Independent Board Members, is required under the 1940 Act to review and approve 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.”
In response to a request on behalf of the Independent Board Members by independent legal counsel, the Board received and reviewed prior to the May Meeting extensive materials specifically prepared for the annual review of Advisory Agreements by the Adviser as well as by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent provider of investment company data. The materials provided in connection with the annual review covered a breadth of subject matter including, but not limited to, a description of the nature, extent and quality of services provided by the Fund Advisers; a review of the Sub-Adviser and investment team; 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- Adviser; and a description of indirect benefits received by the Fund Advisers as a result of their relationships with the Nuveen funds. The Board Members held an in-person meeting on April 17-18, 2019 (the “April Meeting”), in part, to review and discuss the performance of the Nuveen funds and the Adviser’s evaluation of the various sub-advisers to the Nuveen funds. The Independent Board Members asked questions and requested additional information that was provided for the May Meeting.
The information prepared specifically for the annual review of the Advisory Agreements supplemented the information provided to the Board and its committees throughout the year. The Board and its committees met regularly during the year and the information provided and topics discussed were relevant to the review of the Advisory Agreements. Some of these reports and other data included, among other things, materials that outlined the investment performance of the Nuveen funds; strategic plans of the Adviser which may impact the services it provides to the Nuveen funds; the review of the Nuveen funds and applicable investment teams; compliance, regulatory and risk management matters; the trading practices of the various sub-advisers; valuation of securities; fund expenses; payments to financial intermediaries, including 12b-1 fees and sub-transfer agency fees; and overall market and regulatory developments. The Board further 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 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 Fund 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.
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.
In deciding to renew the Advisory Agreements, the Independent Board Members did not identify a particular factor or information as determinative or controlling, but rather the decision reflected the comprehensive consideration of all the information provided, 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 Board recognized that the Adviser provides a comprehensive set of services necessary to operate the Nuveen funds in a highly regulated industry and noted that the scope of such services has expanded over the years as a result of regulatory, market and other developments, such as the development of the liquidity management program and expanded compliance programs. Some of the functions the Adviser is responsible for include, but are not limited to: product management (such as analyzing a fund’s position in the marketplace, setting dividends, preparing shareholder and intermediary communications and other due diligence support); investment oversight (such as analyzing fund performance, sub-advisers and investment teams and analyzing trade executions of portfolio transactions, soft dollar practices and securities lending activities); securities valuation services (such as executing the daily valuation process for portfolio securities and developing and recommending changes to valuation policies and procedures); risk management (such as overseeing operational and investment risks, including stress testing); fund administration (such as preparing fund tax returns and other tax compliance services, overseeing the Nuveen 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 oversight and liaison of transfer agent service providers which include registered shareholder customer service and transaction processing); 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 developing and maintaining a compliance program to ensure compliance with applicable laws and regulations, monitoring compliance with applicable fund policies and procedures and adherence to investment restrictions, and evaluating the compliance programs of the Nuveen fund sub-advisers and certain other service providers); and legal support and oversight of outside law firms (such as with respect to filing and updating registration statements; maintaining various regulatory registrations; and providing legal interpretations regarding fund activities, applicable regulations and implementation of policies and procedures). In reviewing the scope and quality of services, the Board recognized the continued efforts and resources the Adviser and its affiliates have employed to continue to enhance their services for the benefit of the complex as well as particular Nuveen funds over recent years. Such service enhancements have included, but are 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, repositioning funds, merging funds, introducing additional share classes, reviewing and updating investment policies and benchmarks, modifying the composition of certain portfolio management teams and analyzing various data to help devise such improvements; |

| • | Expanded Dividend Management Services – continuing to expand the services necessary to manage the dividends among the varying types of Nuveen funds that have developed as the Nuveen complex has grown in size and scope. |
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. The Board noted that the Adviser oversees the Sub-Adviser and 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 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 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 the investment performance of the Nuveen funds they advise. In this regard, the Board reviewed Fund performance over the quarter, one- , three- and five-year periods ending December 31, 2018 as well as performance data for the first quarter of 2019 ending March 29, 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, 2018. The Board considered the Adviser’s analysis of each fund’s performance, with particular focus on funds that were considered performance outliers and the factors contributing to their performance. The Board also noted that it received performance data of the Nuveen funds during its quarterly meetings throughout the year and took into account the discussions that occurred at these Board meetings regarding fund performance. In this regard, in its evaluation of Nuveen fund performance at meetings throughout the year, the Board considered performance information for the funds for different time periods, both absolute and relative to appropriate benchmarks and peers, with particular attention to information indicating underperformance of the respective funds and discussed with the Adviser the reasons for such underperformance.
The Board reviewed both absolute and relative fund performance during the annual review. 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). 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) 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. Depending on the facts and circumstances, however, 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. In addition, the performance data may vary significantly depending on the end date selected, and shareholders may evaluate fund performance based on their own holding period which may differ from the performance periods reviewed by the Board leading to different results. Further, the Board considered a fund’s performance in light of the overall financial market conditions during the respective periods. As noted above, the Board reviewed, among other things, Nuveen fund performance over various periods ended December 31, 2018, and the Board was aware of the market decline in the fourth quarter of 2018 and considered performance from the first quarter of 2019 as well. The Board also noted that a shorter period of underperformance may significantly impact longer term performance.
In their review of performance, the Independent Board Members focused, in particular, on the Adviser’s analysis of Nuveen funds determined to be underperforming performance outliers. The Board recognized that some periods of underperformance may only be temporary while other periods of underperformance may indicate a broader issue that may require a corrective action. Accordingly, 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 ranked in the third quartile of its Performance Peer Group for the one-year period and first quartile for the three- and five-year periods. In addition, although the Fund’s performance was below the performance of its benchmark for the one-year period, the Fund outperformed its benchmark for the three- and five-year periods. The Board was satisfied with the Fund’s overall performance.
For Nuveen Intermediate Duration Municipal Bond Fund (the “Intermediate Fund”), the Board noted that the Fund ranked in the first quartile of its Performance Peer Group for the one-, three- and five-year periods. Although the Fund’s performance was below the performance of its benchmark for the one-year period, the Fund outperformed its benchmark for the three- and five-year periods. 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 one-, three- and five-year periods, the Fund ranked in the first quartile of its Performance Peer Group for the one-year period and second quartile for the three- and five-year periods. 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 one-, three- and five-year periods, the Fund ranked in the second quartile of its Performance Peer Group for the one- and five-year periods and third quartile for the three-year period. The Board was satisfied with the Fund’s overall performance.
C. Fees, Expenses and Profitability
1. Fees and Expenses
In its annual review, the Board considered the fees paid to the Fund Advisers and the total operating expense ratio of each Nuveen fund, before and after any undertaking by Nuveen to limit the fund’s total annual operating expenses to certain levels. 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 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 $51.5 million and fund-level breakpoints reduced fees by $55.1 million in 2018. Further, fee caps and waivers for all applicable Nuveen funds saved an additional $15 million in fees for shareholders in 2018.
With respect to the Sub-Adviser, the Board considered the sub-advisory fee paid to the Sub-Adviser, including any breakpoint schedule, and as described below, comparative data of the fees the Sub-Adviser charges to other clients, if any.
The Independent Board Members noted that (a) 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; (b) the Intermediate 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 (c) the All-American Fund had a net management fee and a net expense ratio that were below the respective peer averages. 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 reviewed 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 exchange-traded funds 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.
Annual Investment Management Agreement Approval Process(Unaudited) (continued)
In addition to the comparative fee data, the Board also reviewed, among other things, a description of the different levels of services provided to certain other clients compared to the services provided to the Nuveen funds 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 noted, among other things, the wide range of services in addition to investment management services provided to the Nuveen funds when the Adviser is principally responsible for all aspects of operating the funds, including the increased regulatory requirements that must be met in managing the funds, the larger account sizes of managed accounts and the increased entrepreneurial, legal and regulatory risks that the Adviser incurs in sponsoring and managing the 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
In conjunction with their review of fees, the Independent Board Members considered information regarding Nuveen’s level of profitability for its advisory services to the Nuveen funds for the calendar years 2018 and 2017. 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 adjusted 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 exchange-traded fund product line that was launched in 2016. The Independent Board Members noted that Nuveen’s net margins were higher in 2018 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 considered the costs of investments in the Nuveen business, including the investment of seed capital in certain Nuveen funds and additional investments in infrastructure and technology. The Independent Board Members also noted that Nuveen’s adjusted margins from its relationships with the Nuveen funds were on the low range compared to the adjusted margins of the peers; however, the Independent Board Members recognized the inherent limitations of the comparative data of other publicly traded peers given that the calculation of profitability is rather subjective and numerous factors (such as types of funds, business mix, cost of capital, methodology to allocate expenses and other factors) can have a significant impact on the results.
The Independent Board Members also reviewed a description of the expense allocation methodology employed to develop the financial information and a summary of the history of changes to the methodology over the ten-year period from 2008 to 2018, and recognized that other reasonable allocation methodologies could be employed and lead to significantly different results. The Board noted that two Independent Board Members, along with independent counsel, serve as the Board’s liaisons to review profitability and discuss any proposed changes to the methodology prior to the full Board’s review.
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 2018 and 2017 calendar years to consider the financial strength of TIAA having recognized the importance of having an adviser with significant resources.
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 the Sub-Adviser’s revenues, expenses and revenue margins (pre- and post-tax) for its advisory activities for the calendar year ended December 31, 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 ending December 31, 2018 and the pre- and post-tax revenue margin from 2018 and 2017.
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
With respect to economies of scale, the Independent Board Members noted that although economies of scale are difficult to measure, the Adviser shares the benefits of economies of scale in various ways including breakpoints in the management fee schedule (subject to limited exceptions), fee waivers and/or expense limitations, the pricing of Nuveen funds at scale at inception and investments in its business which can enhance the services provided to the funds for the fees paid. With respect to breakpoint schedules, because the Board had previously recognized that economies of scale may occur not only when the assets of a particular Nuveen fund grow but also when the assets in the complex grow, the Nuveen funds generally pay
the Adviser a management fee comprised of a fund-level component and a complex-level component each with its own breakpoint schedule, subject to certain exceptions. In general terms, the breakpoint schedule at the fund level reduces fees as assets in the particular fund pass certain thresholds and the breakpoint schedule at the complex level reduces fees on the Nuveen funds as the eligible assets in the complex pass certain thresholds. The Independent Board Members reviewed, among other things, the fund-level and complex-level fee schedules and 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 2017 and 2018), including the permanent expense cap applicable to the Intermediate Fund. The Independent Board Members noted that as a result of fund-level management fee changes implemented in June 2017, none of the Nuveen open-end funds were above their top level fee breakpoint.
In addition, the Independent Board Members recognized the Adviser’s continued reinvestment in its business through, among other things, investments in its business infrastructure and information technology, portfolio accounting system as well as 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 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 as a result of serving as principal underwriter. In addition, the Independent Board Members also noted that the Sub-Adviser engages in soft dollar transactions pursuant to which it may receive the benefit of research products and other services provided by broker-dealers executing portfolio transactions on behalf of the applicable Nuveen funds.
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 noted 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 their 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.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.
The following tables show the amount of fees that PricewaterhouseCoopers LLP, the Funds’ auditor, billed to the Funds’ during the Funds’ last two full fiscal years. The Audit Committee approved in advance all audit services and non-audit services that PricewaterhouseCoopers LLP, provided to the Funds, except for those non-audit services that were subject to the pre-approval exception under Rule 2-01 of Regulation S-X (the “pre-approval exception”). The preapproval exception for services provided directly to the Funds waives the pre-approval requirement for services other than audit, review or attest services if: (A) the aggregate amount of all such services provided constitutes no more than 5% of the total amount of revenues paid by the Funds during the fiscal year in which the services are provided; (B) the Funds did not recognize the services as non-audit services at the time of the engagement; and (C) the services are promptly brought to the Audit Committee’s attention, and the Committee (or its delegate) approves the services before the audit is completed.
The Audit Committee has delegated certain pre-approval responsibilities to its Chair (or, in her absence, any other member of the Audit Committee).
