Chairman’s Letter to Shareholders

Dear Shareholders,

After a prolonged absence, volatility has returned to the markets in 2018. Last year, the markets seemed willing to shrug off any bad news. But in the first few months of 2018, a backdrop of greater economic uncertainty has made markets more reactive to daily headlines. As interest rates have moved off of historic lows and inflation has ticked higher, the economy’s ability to withstand tighter financial conditions is hard to predict. At the same time, there are concerns that the newly enacted tax reform could overheat the economy. How the U.S. Federal Reserve (Fed) will manage these conditions is under intense scrutiny, particularly in light of the Fed’s leadership change in February 2018.

Growth forecasts for the world’s major economies remain expansionary, although some indicators have pointed to slower momentum this year. Moreover, inflationary pressures and tightening financial conditions could become headwinds, and trade policy and geopolitics remain uncertain. A trade war has implications for both the supply and demand sides of the economy, which complicates the outlook for businesses, consumers and the economy as a whole.

While the risks surrounding trade, monetary and fiscal policy may have increased, there is still opportunity for upside. Recession risk continues to look low, global economies are still expanding and corporate profits have continued to be healthy. Fundamentals, not headlines, drive markets over the long term. And, it’s easy to forget the relative calm over the past year was the outlier. A return to more historically normal volatility levels is both to be expected and part of the healthy functioning of the markets.

Context and perspective are important. If you’re investing for long-term goals, stay focused on the long term, as temporary bumps may smooth over time. Individuals that have shorter timeframes could also benefit from sticking to a clearly defined investment strategy with a portfolio designed for short-term needs. Your financial advisor can help you determine if your portfolio is properly aligned with your goals, timeline and risk tolerance, as well as help you differentiate the noise from what really matters. 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,

William J. Schneider
Chairman of the Board
May 21, 2018

These Funds feature portfolio management by Nuveen Asset Management, LLC (NAM), an affiliate of Nuveen, LLC. Portfolio managers Michael S. Hamilton and Scott R. Romans, PhD, discuss U.S. economic and municipal market conditions, key investment strategies and the twelve-month performance of the Nuveen Select Portfolios (the “Funds”). Michael has managed the three national Funds since 2016, while Scott has managed NXC since 2003 and NXN since 2011.

What factors affected the U.S. economy and national municipal bond market during the twelve-month reporting period ended March 31, 2018?

After hovering near an annual pace of 3% for most of the reporting period, U.S. gross domestic product (GDP) growth cooled to 2.3% in the first quarter of 2018, according to the Bureau of Economic Analysis “advance” estimate. GDP is 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. A beginning-of-the-year slowdown was expected given the seasonal trend of slower first quarter growth seen over the past few years and the delayed impact of tax cuts on workers’ paychecks.

Nevertheless, consumer spending, boosted by employment and wage gains, continued to drive the economy. The Atlantic coast hurricanes in September and October 2017 temporarily weakened shopping and dining out activity, but rebuilding efforts had a positive impact on the economy. Although business investment slowed in early 2018 from the gains seen in the second half of 2017, business sentiment remained strong and hiring continued to boost employment. As reported by the Bureau of Labor Statistics, the unemployment rate fell to 4.1% in March 2018 from 4.5% in March 2017 and job gains averaged around 188,000 per month for the past twelve months. While the jobs market has continued to tighten, wage growth has remained lackluster during this economic recovery. However, the January jobs report revealed an unexpected pickup in wages, which triggered a broad sell-off in equities, despite tame inflation readings. The Consumer Price Index (CPI) increased 2.4% over the twelve-month reporting period ended March 31, 2018 on a seasonally adjusted basis, as reported by the Bureau of Labor Statistics. The core CPI (which excludes food and energy) increased 2.1% during the same period, slightly above the Federal Reserve’s (Fed) unofficial longer term inflation objective of 2.0%.

Portfolio Managers’ Comments (continued)

The housing market also continued to improve with low mortgage rates and low inventory driving home prices higher. The S&P CoreLogic Case-Shiller U.S. National Home Price Index, which covers all nine U.S. census divisions, recorded a 6.3% annual gain in February 2018 (most recent data available at the time this report was prepared). The 10-City and 20-City Composites reported year-over-year increases of 6.5% and 6.8%, respectively.

With the U.S. economy delivering a sustainable growth rate and employment strengthening, the Fed’s policy making committee continued to incrementally raise its main benchmark interest rate. The most recent increase, in March 2018, was the sixth rate hike since December 2015. In addition, in October 2017, the Fed began reducing its balance sheet by allowing a small amount of maturing Treasury and mortgage securities to roll off without reinvestment. The market expects the pace to remain moderate and predictable, with minimal market disruption.

Fed Chair Janet Yellen’s term expired in February 2018, and incoming Chairman Jerome Powell indicated he would likely maintain the Fed’s gradual pace of interest rate hikes. At the March meeting, the Fed kept its projection for three interest rate increases in 2018. However, investors remained concerned that the 2017 Tax Cuts and Jobs Act fiscal stimulus and a recent pick-up in inflation have increased the risk of a Fed policy misstep.

The markets also continued to react to geopolitical news. Protectionist rhetoric had been garnering attention across Europe, as anti-European Union (EU) sentiment featured prominently (although did not win a majority) in the Dutch, French, German and Italian elections held in 2017 and early 2018. In March, the U.S.’s surprise announcement of steel and aluminum tariffs, followed by China’s retaliatory measures, sparked fears of a trade war and added uncertainty to the ongoing North American Free Trade Agreement (NAFTA) talks. Also in March 2018, the U.K. and EU agreed in principle to the Brexit transition terms, opening the door to the next round of negotiation dealing with trade and security issues. The U.S. Treasury issued additional sanctions on Russia (announced in April 2018, after the close of the reporting period) and speculation increased that Iran would be next.

The broad municipal bond market gained moderately in this reporting period, although not without volatility. For most of the reporting period, municipal bonds continued to rebound from the post-election sell-off in the fourth quarter of 2016. After President Trump’s surprising win, bond markets repriced his reflationary fiscal agenda, driving interest rates higher. Municipal bonds suffered a surge in investor outflows due to speculation that the Trump administration’s tax reform proposals could adversely impact municipal bonds.

However, the economy sustained its moderate growth with low inflation, an improving jobs market and modest wage growth, and progress on the White House’s agenda was slow. This backdrop helped municipal bond yields and valuations return to pre-election levels and reverse the trend of outflows. Fundamental credit conditions continued to be favorable overall, while the ongoing high-profile difficulties in Puerto Rico, Illinois and New Jersey were contained.

After the new administration’s health care and immigration reforms met obstacles, Congress refocused on tax reform initiatives in the latter months of 2017. Early drafts of the bill fostered significant uncertainty about the impact on the municipal bond market, leading municipal bonds to underperform taxable bonds in December and provoking issuers to rush bond offerings ahead of the pending tax law. Issuance in December reached an all-time high of $62.5 billion, exacerbating the market’s price decline during the month. However, all of the supply was absorbed and municipal bond valuations subsequently returned to more typical levels.

The final tax reform legislation signed on December 27, 2017 largely spared municipal bonds and was considered neutral to positive for the municipal market overall. Notably, a provision that would have eliminated the tax-preferred status of 20 to 30% of the municipal bond market was not included in the final bill. Moreover, investors were relieved that the adopted changes apply only to newly issued municipal bonds and also could be beneficial from a technical standpoint. Because new issue advance refunding bonds are no longer tax exempt, the total supply of municipal bonds will decrease going forward, boosting the scarcity value of existing municipal bonds. The new tax law also caps the state and local tax (SALT) deduction for individuals, which will likely increase demand for tax-exempt municipal bonds, especially in states with high income and/or property taxes.

Following the issuance surge in late 2017, issuance remained sharply lower in early 2018. However, the overall balance of municipal bond supply and demand remained advantageous for prices. Municipal bond issuance nationwide totaled $406.9 billion in this reporting period, an 8.3% drop from the issuance for the twelve-month reporting period ended March 31, 2017. The robust pace of issuance seen since the low volume depths of 2011 began to moderate in 2017 as interest rates moved higher. Despite the increase, the overall level of interest rates still remained low, encouraging 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 40%-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 strong, the net has not, and this

6

was an overall positive technical factor on municipal bond investment performance in recent years. Although the pace of refundings is slowing, net negative issuance is expected to continue.

Despite the volatility surrounding the potential tax law changes, demand remained robust and continued to outstrip supply. Low global interest rates have continued to drive investors toward higher after-tax yielding assets, including U.S. municipal bonds. As a result, municipal bond fund inflows steadily increased in 2017 overall.

How were the economic and market environments in California and New York during the twelve-month reporting period ended March 31, 2018?

California’s $2.6 trillion economy is the largest in the United States and ranks fifth in the world, according to the International Monetary Fund. California job growth continues to outpace the national average, driven by high technology, international trade and tourism but also supplemented by better residential construction and real estate conditions. As a result, the state’s non-seasonally adjusted unemployment rate was 4.3% as of March 2018, down from 5.0% the year prior, and the gap between California and the nation’s 4.1% unemployment rate is narrowing. According to the S&P CoreLogic Case-Shiller Index, home prices in San Diego, Los Angeles and San Francisco rose 7.6%, 8.3% and 10.1%, respectively, over the twelve months ended February 2018 (most recent data available at the time this report was prepared) compared with an average increase of 6.3% nationally. The enacted Fiscal Year 2018 General Fund budget totals $125.1 billion, which is 3% higher than the revised Fiscal Year 2017 budget. Strong revenue growth due to a recovering economy and the additional personal income tax revenue from the passage of Proposition 55 in November 2016 have aided in the state’s fiscal recovery. For Fiscal Year 2018-2019, the proposed General Fund Governor’s Budget totals $131.7 billion. The Governor’s Budget Proposal includes a $5.1 billion transfer to the Rainy Day Fund to reach its maximum constitutional goal of $13.5 billion (or 10% of General Fund revenues) for Fiscal Year 2019, and continues to pay down budgetary debt from past years. The proposal was finalized prior to the enactment of the federal tax reform legislation. The May Revision to the budget will include a preliminary analysis of the likely effects from the new federal tax reform on the state’s General Fund. As of February 2018, S&P’s affirmed its “AA-/stable” rating and outlook on California general obligation (GO) debt and Moody’s affirmed its state GO rating of Aa3 with stable outlook. During the twelve months ended March 31, 2018, municipal issuance in California totaled $59.4 billion, a gross issuance decrease of 13.9% from the twelve months ended March 31, 2017.

New York State’s $1.5 trillion economy represents 8.1% of U.S. gross domestic product and, according to the International Monetary Fund, would be the 11th largest economy in the world on a stand-alone basis. As of March 2018, the state’s unemployment rate registered 4.6%, above the national average of 4.1%. While New York State’s financial profile is still sturdier than it was several years ago, both Fiscal Year 2016 and Fiscal Year 2017 posted General Fund deficits. On a significantly positive note, New York State has collected approximately $10 billion in various settlements and assessments from the financial industry over the past three years. Proceeds from those settlements have been used to bolster reserves, foster economic development upstate and provide funds for the replacement of the Tappan Zee Bridge. The adopted $164 billion budget for Fiscal Year 2018 is 4% higher than the adopted Fiscal Year 2017 budget. The Fiscal Year 2018 budget contains no new taxes but does extend the “millionaire’s tax” surcharge for two years. The budget includes a $1.1 billion increase in education spending. New York is a high-income state, with per capita income at 122% of the U.S. average, the fourth-highest among the 50 states. New York is also a heavily indebted state. According to Moody’s, New York ranked fifth in the nation in debt per capita in 2016 (NY: $3,070; median: $1,006), seventh in debt per capita as a percentage of personal income (NY: 5.3%; median: 2.5%) and eighth in debt to gross state domestic product (NY: 4.2%; median: 2.2%). The state’s pensions have traditionally been well funded, though the funding ratios have declined in recent years. As of March 2018, Moody’s rates New York “Aa1” with a stable outlook. Moody’s upgraded New York State from Aa2 to Aa1 on June 16, 2014, citing the state’s sustained improvements in fiscal governance. S&P rates the state “AA+” with a stable outlook. S&P upgraded New York State from AA to AA+ on July 23, 2014, citing the state’s improved budget framework. New York municipal bond supply totaled $46.3 billion for the twelve-month period ended March 31, 2018, a 3.5% increase from the same period a year earlier. This ranked New York second among state issuers behind only California.

What key strategies were used to manage these Funds during the twelve-month reporting period ended March 31, 2018?

Municipal bonds benefited from a generally favorable macroeconomic backdrop, despite the uncertainties surrounding the tax reform bill and headline-driven noise about trade policy. Credit spreads narrowed, as sentiment improved after the fourth-quarter sell-off and municipal bond fund flows reversed from net negative to net positive. Rates in the short to intermediate range moved higher with the Fed’s rate hikes, while rates on the long end declined slightly amid low inflation, which resulted in a flatter yield curve

Portfolio Managers’ Comments (continued)

over this reporting period. California’s municipal bond market outperformed the broad market, while New York’s market slightly trailed the broad market during this reporting period.

We also note that California and New York are among the states with the highest personal income and property taxes, which will be more meaningfully affected by the new limits on SALT deductions (as discussed in the market conditions section of this commentary). While individual taxpayers in California and New York could see an increased tax burden, we also expect municipal bond demand to remain robust. In-state issues, which offer both state and federal tax advantages, are likely to be especially attractive to taxpayers in high income states. For state and local governments, the ability to raise taxes in the future may be more politically challenging. Bonds backed by tax revenues could face headwinds going forward, and state and local credit profiles could suffer if delays in tax increases hurt pension funding, capital investment or other government spending priorities.

During this time, we continued to take a bottom-up approach to discovering sectors that appeared undervalued as well as individual credits that we believed had the potential to perform well over the long term.

Our trading activity continued to focus on pursuing the Funds’ investment objectives. NXP, NXQ and NXR focused on buying bonds primarily with short call structures, which offer lower duration profiles, to help maintain the Funds’ duration targets. These shorter effective duration bonds were also available at attractive yields because the Fed’s rate hikes were lifting interest rates on the shorter end of the yield curve. We particularly like lower rated, short call structure bonds. Nevertheless, longer duration bonds occasionally presented compelling long-term opportunities, such as purchases we made in “specialty state” issues. Specialty states, those states with high income tax rates, offer tax-exemption from both federal and state income taxes to in-state municipal bond buyers and, as a result, can experience periods of heightened demand. Specialty state municipal bonds also tend to trade at lower yields relative to non-specialty state issues, which can offer an attractive relative value opportunity over time. Two of the more recent specialty state purchases included credits issued for Oregon Facilities Authority Reed College and Oklahoma State Development Finance Authority Health System Revenue Bond Oklahoma University Medicine Project. To fund our buying during the reporting period, we mainly used the proceeds from called bonds and selling some very short-dated paper (due in one year or less). NXQ and NXR also sold some Buckeye Tobacco Settlement bonds after their strong price appreciation. Early in the reporting period, NXQ eliminated its remaining position in Puerto Rico sales tax bonds known as COFINA bonds.

For NXC and NXN, given our expectations for a flattening yield curve, we focused on buying longer maturity (20 years and longer) bonds, especially in the 25- to 30-year range. In the California Fund, we swapped some of the Fund’s tobacco settlement bonds for more favorable structures, further diversifying the Fund’s exposure across both 4% and 5.25% coupon structures. We also modestly added to NXC’s health care allocation and bought several high grade bonds, including credits issued for the local general obligation (GO), local utilities and transportation sectors. The New York Fund added to its tobacco holdings, as well as bought an A rated utility bond and several higher credit quality bonds from the local GO, utilities and transportation sectors. Both NXC and NXN had ample proceeds from called and maturing bonds to fund the new purchases.

As of March 31, 2018, NXP, NXQ and NXN continued to use inverse floating rate securities. We employ inverse floaters for a variety of reasons, including duration management, income enhancement and total return enhancement.

How did the Funds perform during the twelve-month reporting period ended March 31, 2018?

The tables in each Fund’s Performance Overview and Holding Summaries section of this report provide the Funds’ total returns for the one-year, five-year and ten-year periods ended March 31, 2018. Each Fund’s returns on common share net asset value (NAV) are compared with the performance of corresponding market indexes and Lipper classification average.

For the twelve months ended March 31, 2018, the total returns on common share NAV for NXC and NXN outperformed the national S&P Municipal Bond Index and their respective state’s S&P Municipal Bond Index. The three national Funds, NXP, NXQ and NXR, outperformed the national S&P Municipal Bond Index during the twelve-month period.

The factors affecting performance in this reporting period included duration and yield curve positioning, and credit ratings allocations. In addition, the use of leverage affected the performance of NXP, NXQ, NXR and NXN. NXC did not use leverage in this reporting period. Leverage is discussed in more detail later in the Fund Leverage section of this report.

Duration and yield curve positioning contributed positively to the five Funds’ relative performance. In this reporting period, longer duration bonds performed better than those with shorter durations. All five Funds were positioned with overweight allocations to

8

long duration bonds and generally underweight allocations to shorter bonds, which was advantageous to performance. NXC was underweight the shorter duration buckets except at the very front of the yield curve (30 days and lower), where the Fund held an above-benchmark position as part of our income generation strategy.

The five Funds’ bias toward lower rated issues was another positive contributor to performance. The Funds held underweight allocations to AAA and AA rated credits and overweight allocations to A rated and below bonds, which was advantageous because the lower grade segments outperformed the high grade segments in this reporting period. NXC was particularly helped by exposures to BBB and below investment grade rated credits, and NXN benefited the most from its holdings in the BBB, below investment grade and non-rated categories.

Sector positioning had a muted impact on performance during the reporting period, as it was a slight detractor for NXQ and NXN and neutral for NXP, NXR, and NXC. NXP, NXQ and NXR, however, saw notable outperformance from our credit selection. Bonds bought early in the reporting period when interest rates were rising tended to underperform in this reporting period. But the relative drag was more than offset by strong performance from lower rated credits held during the reporting period, including the three Funds’ positions in Chicago, Chicago-related and Illinois bonds.

An Update Involving Puerto Rico

As noted in the Funds’ previous shareholder reports, we continue to monitor situations in the broader municipal market for any impact on the Funds’ holdings and performance: Puerto Rico’s ongoing debt restructuring is one such case. Puerto Rico began warning investors in 2014 the island’s debt burden might prove to be unsustainable and the Commonwealth pursued various strategies to deal with this burden.

In June 2016, the Puerto Rico Oversight, Management and Economic Stability Act (PROMESA) was signed into law. The legislation established an independent Financial Oversight and Management Board (FOMB) charged with restructuring Puerto Rico’s financial operations and encouraging economic development. In May 2017, the oversight board initiated a bankruptcy-like process for the general government, general obligation debt, the Puerto Rico Sales Tax Financing Corporation (COFINA), the Highways and Transportation Authority (HTA), and the Employee Retirement System. Officials have indicated more public corporations could follow.

In mid-September 2017, Puerto Rico was severely impacted by two hurricanes within the span of just two weeks causing massive damage across the island. The disruption in the local economy caused by the hurricanes and anticipated incoming federal aid created the need for revised fiscal plans for all Puerto Rican entities. These revised plans have not yet been approved by the Oversight Board. Importantly, federal resources dedicated to rebuilding and recovery efforts will not be available for bondholders in the revised fiscal plans. As of April 2018 (subsequent to the close of this reporting period), Puerto Rico has defaulted on many of its debt obligations, including General Obligation bonds.

In terms of Puerto Rico holdings, shareholders should note that NXC, NXN and NXP had no exposure to Puerto Rico debt as of the end of this reporting period, while NXQ and NXR had allocations of 0.40% and 0.48%, respectively, at the end of the reporting period, which were all insured. The Puerto Rico credits offered higher yields, added diversification and triple exemption (i.e., exemption from most federal, state and local taxes). Puerto Rico general obligation debt is currently in default and rated Caa3/D/D by Moody’s, S&P and Fitch, respectively, with negative outlooks.

Fund Leverage

IMPACT OF THE FUNDS’ LEVERAGE STRATEGIES ON PERFORMANCE

One important factor impacting the returns of the Funds relative to their comparative benchmarks was the Funds’ use of leverage through investments in inverse floating rate securities, which represent leveraged investments in underlying bonds. The Funds use leverage because our research has shown that, over time, leveraging provides opportunities for additional income, particularly in the recent market environment where short-term market rates are at or near historical lows, meaning that the short-term rates the Fund has been paying on its leveraging instruments have been much lower than the interest the Fund has been earning on its portfolio of long-term bonds that it has bought with the proceeds of that leverage. However, use of leverage also can expose the Fund to additional price volatility. When a Fund uses leverage, the Fund will experience a greater increase in its net asset value if the municipal bonds acquired through the use of leverage increase in value, but it will also experience a correspondingly larger decline in its net asset value if the bonds acquired through leverage decline in value, which will make the Fund’s net asset value more volatile, and its total return performance more variable over time. In addition, income in levered funds will typically decrease in comparison to unlevered funds when short-term interest rates increase and increase when short-term interest rates decrease. Leverage had a negligible impact on the performance of NXP, NXQ and NXR during the current reporting period. The impact of leverage on NXN over the reporting period was positive, while NXC did not use leverage during the reporting period.

As of March 31, 2018, the Funds’ percentages of leverage are as shown in the accompanying table.

 

      NXP     NXQ     NXR     NXC     NXN  
Effective Leverage*     0.89 %   1.44 %   0.00 %   0.00 %   4.06 %

 

* Effective Leverage is a Fund’s effective economic leverage, and includes both regulatory leverage and the leverage effects of certain derivative and other investments in a Fund’s portfolio that increase the Fund’s investment exposure. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values. A Fund, however, 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 settle portfolio trades. Such incidental borrowings are excluded from the calculation of a Fund’s effective leverage ratio.

* Distribution paid in December 2017.
   
** Market Yield is based on the Fund’s current annualized monthly dividend divided by the Fund’s current market price as of the end of the reporting period. 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. It is based on a combined federal and state income tax rate of 24.0%, 24.0%, 24.0%, 33.3% and 30.6% for NXP, NXQ, NXR, NXC and NXN, respectively. When comparing a Fund to investments that generate qualified dividend income, the Taxable-Equivalent Yield would be lower.

Each Fund in this report 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. If a Fund has cumulatively earned more than it has paid in dividends, it will hold the excess in reserve as undistributed net investment income (UNII) as part of the Fund’s net asset value. Conversely, if a Fund has cumulatively paid in dividends more than it has earned, the excess will constitute a negative UNII that will likewise be reflected in the Fund’s net asset value. Each Fund will, over time, pay all its net investment income as dividends to shareholders.

11

Share Information (continued)

As of March 31, 2018, the Funds had positive UNII balances for tax purposes. NXP, NXQ and NXR had positive UNII balances, while NXC and NXN had negative UNII balances for financial reporting purposes.

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 was sourced from or comprised of elements other than net investment income, including capital gains and/or a return of capital, shareholders would have received a notice to that effect. For financial reporting purposes, the composition and per share amounts of each Fund’s dividends for the reporting period are presented in this report’s Statement of Changes in Net Assets and Financial Highlights, respectively. For income tax purposes, distribution information for 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.

EQUITY SHELF PROGRAM

During the current reporting period, NXC was authorized by the Securities and Exchange Commission to issue additional shares through an equity shelf program (Shelf Offering). Under this program, NXC, subject to market conditions, may raise additional capital from time to time in varying amounts and offering methods at a net price at or above the Fund’s NAV per share. The total amount of shares authorized under this Shelf Offering is shown in the accompanying table:

 

      NXC  
Additional authorized shares     600,000 *

 

* Represents additional authorized shares for the period August 16, 2017 through March 31, 2018.

During the current reporting period, NXC sold shares through its Shelf Offering at a weighted average premium to its NAV per share as shown in the accompanying table.

         
      NXC  
Shares sold through Shelf Offering     60,043  
Weighted average premium to NAV per share sold     2.41%

Refer to the Notes to Financial Statements, Note 4 – Fund Shares, Shares Equity Shelf Programs and Offering Costs for further details on Shelf Offerings and the Fund’s transactions.

SHARE REPURCHASES

During August 2017, the Funds’ Board of Trustees reauthorized an open-market share repurchase program, allowing each Fund to repurchase an aggregate of up to approximately 10% of its outstanding shares.

As of March 31, 2018, and since the inception of the Funds’ repurchase programs, the Funds have cumulatively repurchased and retired their outstanding shares as shown in the accompanying table.

Opinion on the Financial Statements
We have audited the accompanying statements of assets and liabilities, including the portfolios of investments, of Nuveen Select Tax-Free Income Portfolio, Nuveen Select Tax-Free Income Portfolio 2, Nuveen Select Tax-Free Income Portfolio 3, Nuveen California Select Tax-Free Income Portfolio, and Nuveen New York Select Tax-Free Income Portfolio (the “Funds”) as of March 31, 2018, the related statements of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and the related notes (collectively, the “financial statements”) and the financial highlights for each of the years in the four-year period then ended. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Funds as of March 31, 2018, the results of their operations for the year then ended, the changes in their net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the four-year period then ended, in conformity with U.S. generally accepted accounting principles. The financial highlights for the year ended March 31, 2014 were audited by other independent registered public accountants whose report, dated May 27, 2014 expressed an unqualified opinion on those financial highlights.

Basis for Opinion
These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements and financial highlights 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 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 and financial highlights 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 and financial highlights, 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 and financial highlights. Such procedures also included confirmation of securities owned as of March 31, 2018, by correspondence with the custodian and brokers or other appropriate auditing procedures. 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 and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more Nuveen investment companies since 2014.

(1) All percentages shown in the Portfolio of Investments are based on net assets.
(2) Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. Optional Call Provisions are not covered by the report of independent registered public accounting firm.
(3) For financial reporting purposes, the ratings disclosed are the highest of Standard & Poor’s Group (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”) rating. This treatment of split-rated securities may differ from that used for other purposes, such as for Fund investment policies. Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated by any of these national rating agencies. Ratings are not covered by the report of independent registered public accounting firm.
(4) Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities, which ensure the timely payment of principal and interest.
(5) Step-up coupon bond, a bond with a coupon that increases (“steps up”), usually at regular intervals, while the bond is outstanding. The rate shown is the coupon as of the end of the reporting period.
(6) As of, or subsequent to, the end of the reporting period, this security is non-income producing. Non-income producing, in the case of a fixed-income security, generally denotes that the issuer has (1) defaulted on the payment of principal or interest, (2) is under the protection of the Federal Bankruptcy Court or (3) the Fund’s Adviser has concluded that the issue is not likely to meet its future interest payment obligations and has ceased accruing additional income on the Fund’s records.
(7) During January 2010, Las Vegas Monorail Company (“Las Vegas Monorail”) filed for federal bankruptcy protection. During March 2012, Las Vegas Monorail emerged from federal bankruptcy with the acceptance of a reorganization plan assigned by the Federal Bankruptcy Court. Under the reorganization plan, the Fund surrendered its Las Vegas Monorail Project Revenue Bonds, First Tier, Series 2000 and in turn received two senior interest corporate bonds: the first with an annual coupon rate of 5.500% maturing on July 15, 2019 and the second with an annual coupon rate of 3.000% (5.500% after December 31, 2015) maturing on July 15, 2055. The Fund was not accruing income for either senior interest corporate bond. On January 18, 2017, the Fund’s Adviser determined it was likely that this senior interest corporate bond would fulfill its obligation on the security maturing on July 15, 2019, and therefore began accruing income on the Fund’s records.
(8) Investment valued at fair value using methods determined in good faith by, or at the discretion of, the Board. For fair value measurement disclosure purposes, investment classified as Level 3. See Notes to Financial Statements, Note 2 – Investment Valuation and Fair Value Measurements for more information.
144A Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.
ETM Escrowed to maturity.
IF Inverse floating rate security issued by a tender option bond (“TOB”) trust, the interest rate on which varies inversely with the Securities Industry Financial Markets Association (SIFMA) short-term rate, which resets weekly, or a similar short-term rate, and is reduced by the expenses related to the TOB trust.
WI/DD Investment, or portion of investment, purchased on a when-issued or delayed delivery basis.

(1) All percentages shown in the Portfolio of Investments are based on net assets.
(2) Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. Optional Call Provisions are not covered by the report of independent registered public accounting firm.
(3) For financial reporting purposes, the ratings disclosed are the highest of Standard & Poor’s Group (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”) rating. This treatment of split-rated securities may differ from that used for other purposes, such as for Fund investment policies. Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated by any of these national rating agencies. Ratings are not covered by the report of independent registered public accounting firm.
(4) Step-up coupon bond, a bond with a coupon that increases (“steps up”), usually at regular intervals, while the bond is outstanding. The rate shown is the coupon as of the end of the reporting period.
(5) Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities, which ensure the timely payment of principal and interest.
(6) As of, or subsequent to, the end of the reporting period, this security is non-income producing. Non-income producing, in the case of a fixed-income security, generally denotes that the issuer has (1) defaulted on the payment of principal or interest, (2) is under the protection of the Federal Bankruptcy Court or (3) the Fund’s Adviser has concluded that the issue is not likely to meet its future interest payment obligations and has ceased accruing additional income on the Fund’s records.
(7) During January 2010, Las Vegas Monorail Company (“Las Vegas Monorail”) filed for federal bankruptcy protection. During March 2012, Las Vegas Monorail emerged from federal bankruptcy with the acceptance of a reorganization plan assigned by the Federal Bankruptcy Court. Under the reorganization plan, the Fund surrendered its Las Vegas Monorail Project Revenue Bonds, First Tier, Series 2000 and in turn received two senior interest corporate bonds: the first with an annual coupon rate of 5.500% maturing on July 15, 2019 and the second with an annual coupon rate of 3.000% (5.500% after December 31, 2015) maturing on July 15, 2055. The Fund was not accruing income for either senior interest corporate bond. On January 18, 2017, the Fund’s Adviser determined it was likely that this senior interest corporate bond would fulfill its obligation on the security maturing on July 15, 2019, and therefore began accruing income on the Fund’s records.
(8) Investment valued at fair value using methods determined in good faith by, or at the discretion of, the Board. For fair value measurement disclosure purposes, investment classified as Level 3. See Notes to Financial Statements, Note 2 – Investment Valuation and Fair Value Measurements for more information.
144A Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.
ETM Escrowed to maturity.
IF Inverse floating rate security issued by a tender option bond (“TOB”) trust, the interest rate on which varies inversely with the Securities Industry Financial Markets Association (SIFMA) short-term rate, which resets weekly, or a similar short-term rate, and is reduced by the expenses related to the TOB trust.
WI/DD Investment, or portion of investment, purchased on a when-issued or delayed delivery basis.

(1) All percentages shown in the Portfolio of Investments are based on net assets.
(2) Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. Optional Call Provisions are not covered by the report of independent registered public accounting firm.
(3) For financial reporting purposes, the ratings disclosed are the highest of Standard & Poor’s Group (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”) rating. This treatment of split-rated securities may differ from that used for other purposes, such as for Fund investment policies. Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated by any of these national rating agencies. Ratings are not covered by the report of independent registered public accounting firm.
(4) Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities, which ensure the timely payment of principal and interest.
(5) Step-up coupon bond, a bond with a coupon that increases (“steps up”), usually at regular intervals, while the bond is outstanding. The rate shown is the coupon as of the end of the reporting period.
(6) As of, or subsequent to, the end of the reporting period, this security is non-income producing. Non-income producing, in the case of a fixed-income security, generally denotes that the issuer has (1) defaulted on the payment of principal or interest, (2) is under the protection of the Federal Bankruptcy Court or (3) the Fund’s Adviser has concluded that the issue is not likely to meet its future interest payment obligations and has ceased accruing additional income on the Fund’s records.
(7) During January 2010, Las Vegas Monorail Company (“Las Vegas Monorail”) filed for federal bankruptcy protection. During March 2012, Las Vegas Monorail emerged from federal bankruptcy with the acceptance of a reorganization plan assigned by the Federal Bankruptcy Court. Under the reorganization plan, the Fund surrendered its Las Vegas Monorail Project Revenue Bonds, First Tier, Series 2000 and in turn received two senior interest corporate bonds: the first with an annual coupon rate of 5.500% maturing on July 15, 2019 and the second with an annual coupon rate of 3.000% (5.500% after December 31, 2015) maturing on July 15, 2055. The Fund was not accruing income for either senior interest corporate bond. On January 18, 2017, the Fund’s Adviser determined it was likely that this senior interest corporate bond would fulfill its obligation on the security maturing on July 15, 2019, and therefore began accruing income on the Fund’s records.
(8) Investment valued at fair value using methods determined in good faith by, or at the discretion of, the Board. For fair value measurement disclosure purposes, investment classified as Level 3. See Notes to Financial Statements, Note 2 – Investment Valuation and Fair Value Measurements for more information.
144A Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.
ETM Escrowed to maturity.
WI/DD Investment, or portion of investment, purchased on a when-issued or delayed delivery basis.

(1) All percentages shown in the Portfolio of Investments are based on net assets.
(2) Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. Optional Call Provisions are not covered by the report of independent registered public accounting firm.
(3) For financial reporting purposes, the ratings disclosed are the highest of Standard & Poor’s Group (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”) rating. This treatment of split-rated securities may differ from that used for other purposes, such as for Fund investment policies. Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated by any of these national rating agencies. Ratings are not covered by the report of independent registered public accounting firm.
(4) Step-up coupon bond, a bond with a coupon that increases (“steps up”), usually at regular intervals, while the bond is outstanding. The rate shown is the coupon as of the end of the reporting period.
(5) Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities, which ensure the timely payment of principal and interest.
(6) Investment has a maturity of greater than one year, but has variable rate and/or demand features which qualify it as a short-term investment. The rate disclosed, as well as the reference rate and spread, where applicable, is that in effect as of the end of the reporting period. This rate changes periodically based on market conditions or a specified market index.
144A Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.

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

Notes to Financial Statements

1. General Information and Significant Accounting Policies

General Information

Fund Information

The funds covered in this report and their corresponding New York Stock Exchange (“NYSE”) symbols are as follows (each a “Fund” and collectively, the “Funds”):

• Nuveen Select Tax-Free Income Portfolio (NXP)
• Nuveen Select Tax-Free Income Portfolio 2 (NXQ)
• Nuveen Select Tax-Free Income Portfolio 3 (NXR)
• Nuveen California Select Tax-Free Income Portfolio (NXC)
• Nuveen New York Select Tax-Free Income Portfolio (NXN)

The Funds are registered under the Investment Company Act of 1940, as amended, as diversified closed-end management investment companies. NXP, NXQ, NXR, NXC, and NXN were organized as Massachusetts business trusts on January 29, 1992, March 30, 1992, May 28, 1992, March 30, 1992, and March 30, 1992, respectively.

The end of the reporting period for the Funds is March 31, 2018, and the period covered by these Notes to Financial Statements is the fiscal year ended March 31, 2018 (the “current fiscal period”).

Investment 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.

Investment Objectives and Principal Investment Strategies
Each Fund seeks to provide current income and stable dividends, exempt from regular federal and designated state income taxes, where applicable, consistent with the preservation of capital by investing primarily in a portfolio of municipal obligations.

Significant Accounting Policies
Each Fund is an investment company and follows accounting and reporting guidance under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (ASC) Topic 946 “Financial Services – Investment Companies.” The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”).

Investment Transactions
Investment transactions are recorded on a trade date basis. Realized gains and losses from investment transactions are determined on the specific identification method, which is the same basis used for federal income tax purposes. Investments purchased on a when-issued/delayed delivery basis may have extended settlement periods. Any investments so purchased are subject to market fluctuation during this period. The 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.

As of the end of the reporting period, the following Funds’ outstanding when-issued/delayed delivery purchase commitments were as follows:

                     
      NXP     NXQ     NXR  
Outstanding when-issued/delayed delivery purchase commitments   $ 467,764   $ 483,894   $ 370,985  

Investment Income
Investment income is comprised of interest income, which reflects the amortization of premiums and accretion of discounts for financial reporting purposes, and is recorded on an accrual basis. 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.

66

Professional Fees
Professional fees presented on the Statement of Operations consist of legal fees incurred in the normal course of operations, audit fees, tax consulting fees and, in some cases, workout expenditures. Workout expenditures are incurred in an attempt to protect or enhance an investment or to pursue other claims or legal actions on behalf of Fund shareholders. If a refund is received for workout expenditures paid in a prior reporting period, such amounts will be recognized as “Legal fee refund” on the Statement of Operations.

Dividends and Distributions to Shareholders
Dividends from net investment income, if any, are declared monthly. Net realized capital gains and/or market discount from investment transactions, if any, are distributed to shareholders at least annually. Furthermore, capital gains are distributed only to the extent they exceed available capital loss carryforwards.

Distributions to shareholders of net investment income, net realized capital gains and/or market discount, if any, are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

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

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

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 3 – Portfolio Securities and Investments in Derivatives.

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

2. Investment Valuation and Fair Value Measurements

The fair valuation input levels as described below are for fair value measurement purposes.

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, prepayment speeds, credit risk, etc.).
  Level 3 – Prices are determined using significant unobservable inputs (including management’s assumptions in determining the fair value of investments).
67

Notes to Financial Statements (continued)

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.

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 net asset value (“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:

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

The Valuation Committee will consider pricing methodologies it deems relevant and appropriate when making a fair value determination, based on the facts and circumstances specific to the portfolio instrument. Fair value determinations generally will be derived as follows, using public or private market information:

     
  (i) If available, fair value determinations shall be derived by extrapolating from recent transactions or quoted prices for identical or comparable securities.
     
  (ii) If such information is not available, an analytical valuation methodology may be used based on other available information including, but not limited to: analyst appraisals, research reports, corporate action information, issuer financial statements and shelf registration statements. Such analytical valuation methodologies may include, but are not limited to: multiple of earnings, discount from market value of a similar freely-traded security, discounted cash flow analysis, book value or a multiple thereof, risk premium/yield analysis, yield to maturity and/or fundamental investment analysis.

The purchase price of a portfolio instrument will be used to fair value the instrument only if no other valuation methodology is available or deemed appropriate, and it is determined that the purchase price fairly reflects the instrument’s current value.

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

3. 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 of the 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 downside 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

69

Notes to Financial Statements (continued)

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.

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     NXP     NXQ     NXR     NXC     NXN  
Floating rate obligations: self-deposited Inverse Floaters   $   $   $   $   $ 425,000  
Floating rate obligations: externally-deposited Inverse Floaters     2,250,000     3,750,000             1,890,000  
Total   $ 2,250,000   $ 3,750,000   $   $   $ 2,315,000  

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

 

                                 
Self-Deposited Inverse Floaters     NXP     NXQ     NXR     NXC     NXN  
Average floating rate obligations outstanding   $   $   $   $   $ 836,562  
Average annual interest rate and fees     %   %   %   %   1.50 %

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 is 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.

70

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     NXP     NXQ     NXR     NXC     NXN  
Maximum exposure to Recourse Trusts: self-deposited Inverse Floaters   $   $   $   $   $ 425,000  
Maximum exposure to Recourse Trusts: externally-deposited Inverse Floaters     2,250,000     3,750,000              
Total   $ 2,250,000   $ 3,750,000   $   $   $ 425,000  

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.

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, such as futures, options and swap contracts. Each Fund limits its investments in futures, options on futures and swap contracts to the extent necessary for the Adviser to claim the exclusion from registration by the Commodity Futures Trading Commission as a commodity pool operator with respect to the Fund. 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.

Although the Funds are authorized to invest in derivative instruments and may do so in the future, they did not make any such investments during the current fiscal period.

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.

4. Fund Shares

Shares Equity Shelf Program and Offering Costs
NXC has filed a registration statement with the Securities and Exchange Commission (“SEC”) authorizing the Fund to issue additional shares through one or more equity shelf programs (“Shelf Offering”), which became effective with the SEC during the current fiscal period.

Under this Shelf Offering, the Fund, subject to market conditions, may raise additional equity capital by issuing additional shares from time to time in varying amounts and by different offering methods at a net price at or above the Fund’s NAV per share. In the event the Fund’s Shelf Offering registration statement is no longer current, the Fund may not issue additional shares until a post-effective amendment to the registration statement has been filed with the SEC.

Additional authorized shares, shares sold and offering proceeds, net of offering costs under the Fund’s Shelf Offering during the Fund’s current fiscal period were as follows:

 

      NXC
      Year
Ended
3/31/18
*
Additional authorized shares     600,000  
Shares sold     60,043  
Offering proceeds, net of offering costs   $ 810,179  

 

* Represents additional authorized shares for the period August 16, 2017 through March 31, 2018.
71

 

Notes to Financial Statements (continued)

Costs incurred by the Fund in connection with its initial shelf registrations are recorded as a prepaid expense and recognized as “Deferred offering costs” on the Statement of Assets and Liabilities. These costs are amortized pro rata as shares are sold and are recognized as a component of “Proceeds from shelf offering, net of offering costs” on the Statement of Changes in Net Assets. Any deferred offering costs remaining one year after effectiveness of the initial shelf registration will be expensed. Costs incurred by the Fund to keep the shelf registration current are expensed as incurred and recognized as a component of “Other expenses” on the Statement of Operations.

Shares Transactions
Transactions in shares during the Funds’ current and prior fiscal period, where applicable, were as follows:

 

      NXC     NXN  
      Year     Year     Year     Year

N/A – The Fund is not authorized to issue additional shares through a shelf offering.

5. Investment Transactions
Long-term purchases and sales (including maturities) during the current fiscal period were as follows:

 

      NXP     NXQ     NXR     NXC     NXN  
Purchases   $ 51,297,914   $ 50,705,468   $ 31,917,395   $ 18,635,589   $ 9,094,809  
Sales and maturities     48,219,410     49,877,417     30,622,847     23,636,838     9,437,980  

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

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, 2018.

 

      NXP     NXQ     NXR     NXC     NXN  
Tax cost of investments   $ 223,208,846   $ 233,141,025   $ 175,110,015   $ 81,575,731   $ 52,034,104

72

Permanent differences, primarily due to distribution reallocations, taxable market discount and federal taxes paid, resulted in reclassifications among the Funds’ components of net assets as of March 31, 2018, the Funds’ tax year end, as follows:

 

      NXP     NXQ     NXR     NXC     NXN  
Paid-in-surplus   $ (182 ) $ (195 ) $ (164 ) $   $  
Undistributed (Over-distribution of) net investment income     (7,839 )   (168,379 )   (80,921 )   (4,003 )   (7,082 )
Accumulated net realized gain (loss)     8,021     168,574     81,085     4,003     7,082  

The tax components of undistributed net tax-exempt income, net ordinary income and net long-term capital gains as of March 31, 2018, the Funds’ tax year end, were as follows:

 

      NXP     NXQ     NXR     NXC     NXN  
Undistributed net tax-exempt income1   $ 553,621   $ 426,599   $ 263,457   $ 53,622   $ 95,779

Undistributed net long-term capital gains                      

 

1 Undistributed net tax-exempt income (on a tax basis) has not been reduced for the dividend declared on March 1, 2018, paid on April 2, 2018.
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, 2018 and March 31, 2017, was designated for purposes of the dividends paid deduction as follows:

2 Net ordinary income consists of taxable market discount income and net short-term capital gains, if any.
3 The Funds hereby designate these amounts paid during the fiscal year ended March 31, 2018, as Exempt Interest Dividends.
4 The Funds hereby designate as long-term capital gain dividend, pursuant to the Internal Revenue Code Section 852(b)(3), the amount necessary to reduce earnings and profits of the Funds related to net capital gain to zero for the tax year ended March 31, 2018.

As of March 31, 2018, the Funds’ tax year end, the following Funds had unused capital loss carryforwards available for federal income tax purposes to be applied against future capital gains, if any. If not applied, the carryforwards will expire as shown in the following table. The losses not subject to expiration will be utilized first by a Fund.

7. Management Fees and Other Transactions with Affiliates

Management Fees
Each Fund’s management fee compensates the Adviser for 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 Fund 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 NXP, is calculated according to the following schedule:

 

      NXP
Average Daily Net Assets     Fund-Level Fee Rate
For the first $125 million     0.0500 %
For the next $125 million     0.0375  
For the next $250 million     0.0250  
For the next $500 million     0.0125  

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

      NXQ
      NXR

Average Daily Net Assets     Fund-Level Fee Rate
For the first $125 million     0.1000 %
For the next $125 million     0.0875  
For the next $250 million     0.0750  
For the next $500 million     0.0625

For the next $3 billion     0.0250  
For managed assets over $5 billion     0.0125  

The annual complex-level fee, payable monthly, for each Fund is calculated by multiplying the current complex-wide fee rate, determined according to the following schedule by the Fund’s daily net assets: 

 

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

$300 billion     0.1445  

 

* For the complex-level fees, managed assets include closed-end fund assets managed by the Adviser that are attributable to certain types of leverage. For these purposes, leverage includes the 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 managed assets in certain circumstances. The complex-level fee is calculated based upon the aggregate daily managed assets of all Nuveen open-end and closed-end funds that constitute “eligible assets.” Eligible assets do not include assets attributable to investments in other Nuveen funds or assets in excess of a determined amount (orignally $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. As of March 31, 2018, the complex-level fee for each Fund was 0.1595%.

Other Transactions with Affiliates
Each Fund is permitted to purchase or sell securities from or to certain other funds managed by the 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 of 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.

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

 

               
Inter-Fund Trades     NXP     NXQ  
Purchases   $   $ 1,289,153  
Sales     1,289,153      

8. Borrowing Arrangements

Uncommitted Line of Credit
During the current fiscal period, the Funds participated in an unsecured bank line of credit (“Unsecured Credit Line”) under which outstanding balances would bear interest at a variable rate. Although the Funds participated in the Unsecured Credit Line, they did not have any outstanding balances during the current fiscal period.

The Unsecured Credit Line was not renewed after its scheduled termination date on July 27, 2017.

Committed Line of Credit
The Funds, along with certain other funds managed by the Adviser (“Participating Funds”), have established a 364-day, approximately $3 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. A large portion of this facility’s capacity (and its associated costs as described below) is currently dedicated for use by a small number of Participating Funds, which does not include any of the Funds covered by this shareholder report. The remaining capacity under the facility (and the corresponding portion of the facility’s annual costs) is separately dedicated to most of the other open-end funds in the Nuveen fund family, along with a number of Nuveen closed-end funds, including all of the Funds covered by this shareholder report. The credit facility expires in July 2018 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% (1.25% prior to July 27, 2017) per annum or (b) the Fed Funds rate plus 1.00% (1.25% prior to July 27, 2017) per annum on amounts borrowed. Participating Funds paid administration, legal and arrangement fees, which are recognized as a component of “Other expenses” 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 Funds utilized this facility. The Funds’ maximum outstanding balance during the utilization period was as follows:

                                 
      NXP     NXQ     NXR     NXC     NXN  
Maximum Outstanding Balance   $ 153,974   $ 1,279,453   $ 987,978   $ 562,493   $ 431,159  

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

                                 
      NXP     NXQ     NXR     NXC     NXN  
Average daily balance outstanding   $ 153,974   $ 1,279,453   $ 987,978   $ 562,493   $ 431,159  
Average annual interest rate     2.56 %   2.56 %   2.56 %   2.56 %   2.56 %

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

Inter-Fund Borrowing and Lending
The SEC has granted an exemptive order permitting registered open-end and closed-end Nuveen funds to participate in an inter-fund lending facility whereby the Nuveen funds may directly lend to and borrow money from each other for temporary purposes (e.g., to satisfy redemption requests or when a sale of securities “fails,” resulting in an unanticipated cash shortfall) (the “Inter-Fund Program”). The closed-end Nuveen funds, including the

75

Notes to Financial Statements (continued)

Funds covered by this shareholder report, will participate only as lenders, and not as borrowers, in the Inter-Fund Program because such closed-end funds rarely, if ever, need to borrow cash to meet redemptions. The Inter-Fund Program is subject to a number of conditions, including, among other things, the requirements that (1) no fund may borrow or lend money through the Inter-Fund Program unless it receives a more favorable interest rate than is typically available from a bank or other financial institution for a comparable transaction; (2) no fund may borrow on an unsecured basis through the Inter-Fund Program unless the fund’s outstanding borrowings from all sources immediately after the inter-fund borrowing total 10% or less of its total assets; provided that if the borrowing fund has a secured borrowing outstanding from any other lender, including but not limited to another fund, the inter-fund loan must be secured on at least an equal priority basis with at least an equivalent percentage of collateral to loan value; (3) if a fund’s total outstanding borrowings immediately after an inter-fund borrowing would be greater than 10% of its total assets, the fund may borrow through the inter-fund loan on a secured basis only; (4) no fund may lend money if the loan would cause its aggregate outstanding loans through the Inter-Fund Program to exceed 15% of its net assets at the time of the loan; (5) a fund’s inter-fund loans to any one fund shall not exceed 5% of the lending fund’s net assets; (6) the duration of inter-fund loans will be limited to the time required to receive payment for securities sold, but in no event more than seven days; and (7) each inter-fund loan may be called on one business day’s notice by a lending fund and may be repaid on any day by a borrowing fund. In addition, a Nuveen fund may participate in the Inter-Fund Program only if and to the extent that such participation is consistent with the fund’s investment objective and investment policies. The Board is responsible for overseeing the Inter-Fund Program.

The limitations detailed above and the other conditions of the SEC exemptive order permitting the Inter-Fund Program are designed to minimize the risks associated with Inter-Fund Program for both the lending fund and the borrowing fund. However, no borrowing or lending activity is without risk. When a fund borrows money from another fund, there is a risk that the loan could be called on one day’s notice or not renewed, in which case the fund may have to borrow from a bank at a higher rate or take other actions to payoff such loan if an inter-fund loan is not available from another fund. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.

During May 2017, the Board approved the Nuveen funds participation in the Inter-Fund Program. During the current reporting period, none of the Funds covered by this shareholder report have entered into any inter-fund loan activity.

9. New Accounting Pronouncements

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. Management is currently evaluating the implications of ASU 2017-08, if any.

Glossary of Terms Used in this Report (Unaudited)

 

Auction Rate Bond: An auction rate bond is a security whose interest payments are adjusted periodically through an auction process, which process typically also serves as a means for buying and selling the bond. Auctions that fail to attract enough buyers for all the shares offered for sale are deemed to have “failed,” with current holders receiving a formula-based interest rate until the next scheduled auction.
   
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 market 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’s or fund’s duration, the more the price of the bond or fund will change as interest rates change.
   
Effective Leverage: Effective leverage is a fund’s effective economic leverage, and includes both regulatory leverage (see leverage) and the leverage effects of certain derivative investments in the fund’s portfolio. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values, in addition to any regulatory leverage.
 
 
   
Forward Interest Rate Swap: A contractual agreement between two counterparties under which one party agrees to make periodic payments to the other for an agreed period of time based on a fixed rate, while the other party agrees to make periodic payments based on a floating rate of interest based on an underlying index. Alternatively, both series of cashflows to be exchanged could be calculated using floating rates of interest but floating rates that are based upon different underlying indexes.
   
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.
78

 

Net Asset Value (NAV) Per Share: A fund’s Net Assets is equal to its total assets (securities, cash, accrued earnings and receivables) less its total liabilities. NAV per share is equal to the fund’s Net Assets divided by its number of shares outstanding.
   
Pre-Refunding: 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.
   
Regulatory Leverage: Regulatory leverage consists of preferred shares issued by or borrowings of a fund. Both of these are part of a fund’s capital structure. Regulatory leverage is subject to asset coverage limits set in the Investment Company Act of 1940.
   
S&P Municipal Bond California Index: An unleveraged, market value-weighted index designed to measure the performance of the tax-exempt, investment grade California municipal bond market. 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 New York Index: An unleveraged, market value-weighted index designed to measure the performance of the tax-exempt, investment grade New York municipal bond market. 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.
   
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.

Reinvest Automatically, Easily and Conveniently

Nuveen makes reinvesting easy. A phone call is all it takes to set up your reinvestment account.

 

Nuveen Closed-End Funds Automatic Reinvestment Plan

Nuveen Closed-End Fund allows you to conveniently reinvest distributions in additional Fund shares. By choosing to reinvest, you’ll be able to invest money regularly and automatically, and watch your investment grow through the power of compounding. Just like distributions in cash, there may be times when income or capital gains taxes may be payable on distributions that are reinvested. It is important to note that an automatic reinvestment plan does not ensure a profit, nor does it protect you against loss in a declining market.

Easy and convenient

To make recordkeeping easy and convenient, each month you’ll receive a statement showing your total distributions, the date of investment, the shares acquired and the price per share, and the total number of shares you own.

How shares are purchased

The shares you acquire by reinvesting will either be purchased on the open market or newly issued by the Fund. If the shares are trading at or above net asset value at the time of valuation, the Fund will issue new shares at the greater of the net asset value or 95% of the then-current market price. If the shares are trading at less than net as -set value, shares for your account will be purchased on the open market. If the Plan Agent begins purchasing Fund shares on the open market while shares are trading below net asset value, but the Fund’s shares subsequently trade at or above their net asset value before the Plan Agent is able to complete its purchases, the Plan Agent may cease open-market purchases and may invest the uninvested portion of the distribution in newly-issued Fund shares at a price equal to the greater of the shares’ net asset value or 95% of the shares’ market value on the last business day imme -diately prior to the purchase date. Distributions received to purchase shares in the open market will normally be invested shortly after the distribution payment date. No interest will be paid on distributions awaiting reinvestment. Because the market price of the shares may increase before purchases are completed, the average purchase price per share may exceed the market price at the time of valuation, resulting in the acquisition of fewer shares than if the distribution had been paid in shares issued by the Fund. A pro rata portion of any applicable brokerage commissions on open market purchases will be paid by Plan participants. These commissions usually will be lower than those charged on individual transactions.

Flexible

You may change your distribution option or withdraw from the Plan at any time, should your needs or situation change. You can reinvest whether your shares are registered in your name, or in the name of a brokerage firm, bank, or other nominee. Ask your investment advisor if his or her firm will participate on your behalf. Participants whose shares are registered in the name of one firm may not be able to transfer the shares to another firm and continue to participate in the Plan. The Fund reserves the right to amend or terminate the Plan at any time. Although the Fund reserves the right to amend the Plan to include a service charge payable by the participants, there is no direct service charge to participants in the Plan at this time.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

Nuveen Select Tax-Free Income Portfolio

The following tables show the amount of fees that KPMG LLP, the Fund’s auditor, billed to the Fund during the Fund’s last two full fiscal years. For engagements with KPMG LLP the Audit Committee approved in advance all audit services and non-audit services that KPMG LLP provided to the Fund, 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 pre-approval exception for services provided directly to the Fund 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 Fund to its accountant during the fiscal year in which the services are provided; (B) the Fund 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 Chairman (or, in his absence, any other member of the Audit Committee).

connection with statutory and regulatory filings or engagements.
                         
                                 
2 “Audit Related Fees” are the aggregate fees billed for assurance and related services reasonably related to the performance of the audit or review of
         
financial statements that are not reported under “Audit Fees”. These fees include offerings related to the Fund’s common shares and leverage.
         
                                 
3 “Tax Fees” are the aggregate fees billed for professional services for tax advice, tax compliance, and tax planning. These fees include: all global
         
withholding tax services; excise and state tax reviews; capital gain, tax equalization and taxable basis calculation performed by the principal accountant.
         
                                 
4 “All Other Fees” are the aggregate fees billed for products and services other than “Audit Fees”, “Audit-Related Fees” and “Tax Fees”. These fees
         
represent all engagements pertaining to the Fund’s use of leverage.
                         

SERVICES THAT THE FUND’S AUDITOR BILLED TO THE ADVISER AND AFFILIATED FUND SERVICE PROVIDERS

The following tables show the amount of fees billed by KPMG LLP to Nuveen Fund Advisors, LLC (formerly Nuveen Fund Advisors, Inc.) (the “Adviser”), and any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund (“Affiliated Fund Service Provider”), for engagements directly related to the Fund’s operations and financial reporting, during the Fund’s last two full fiscal years.

The tables also show the percentage of fees subject to the pre-approval exception. The pre-approval exception for services provided to the Adviser and any Affiliated Fund Service Provider (other than audit, review or attest services) waives the pre-approval requirement if: (A) the aggregate amount of all such services provided constitutes no more than 5% of the total amount of revenues paid to KPMG LLP by the Fund, the Adviser and Affiliated Fund Service Providers during the fiscal year in which the services are provided that would have to be pre-approved by the Audit Committee; (B) the Fund 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 Fund’s audit is completed.

NON-AUDIT SERVICES

The following table shows the amount of fees that KPMG LLP billed during the Fund’s last two full fiscal years for non-audit services. The Audit Committee is required to pre-approve non- audit services that KPMG LLP provides to the Adviser and any Affiliated Fund Services Provider, if the engagement related directly to the Fund’s operations and financial reporting (except for those subject to the pre-approval exception described above). The Audit Committee requested and received information from KPMG LLP about any non-audit services that KPMG LLP rendered during the Fund’s last fiscal year to the Adviser and any Affiliated Fund Service Provider. The Committee considered this information in evaluating KPMG LLP’s independence.

Less than 50 percent of the hours expended on the principal accountant’s engagement to audit the registrant’s financial statements for the most recent

The following section provides information on the portfolio manager at the Sub-Adviser:

Item 8(a)(1). PORTFOLIO MANAGER BIOGRAPHY

Michael Hamilton, Senior Vice President of Nuveen Asset Management, manages several municipal funds.  He joined Nuveen Asset Management on January 1, 2011 in connection with Nuveen Fund Advisors acquiring a portion of the asset management business of FAF Advisors.  He began working in the financial industry when he joined FAF Advisors in 1989, as a fixed-income fund manager and trader.  He became a portfolio manager in 1992.

POTENTIAL MATERIAL CONFLICTS OF INTEREST

Actual or apparent conflicts of interest may arise when a portfolio manager has day-to-day management responsibilities with respect to more than one account. More specifically, portfolio managers who manage multiple accounts are presented a number of potential conflicts, including, among others, those discussed below.

The management of multiple accounts may result in a portfolio manager devoting unequal time and attention to the management of each account. Nuveen Asset Management seeks to manage such competing interests for the time and attention of portfolio managers by having portfolio managers focus on a particular investment discipline. Most accounts managed by a portfolio manager in a particular investment strategy are managed using the same investment models.

If a portfolio manager identifies a limited investment opportunity which may be suitable for more than one account, an account may not be able to take full advantage of that opportunity due to an allocation of filled purchase or sale orders across all eligible accounts. To deal with these situations, Nuveen Asset Management has adopted procedures for allocating limited opportunities across multiple accounts.

With respect to many of its clients’ accounts, Nuveen Asset Management determines which broker to use to execute transaction orders, consistent with its duty to seek best execution of the transaction. However, with respect to certain other accounts, Nuveen Asset Management may be limited by the client with respect to the selection of brokers or may be instructed to direct trades through a particular broker. In these cases, Nuveen Asset Management may place separate, non-simultaneous, transactions for a Fund and other accounts which may temporarily affect the market price of the security or the execution of the transaction, or both, to the detriment of the Fund or the other accounts.

Some clients are subject to different regulations. As a consequence of this difference in regulatory requirements, some clients may not be permitted to engage in all the investment techniques or transactions or to engage in these transactions to the same extent as the other accounts managed by the portfolio manager. Finally, the appearance of a conflict of interest may arise where Nuveen Asset Management has an incentive, such as a performance-based management fee, which relates to the management of some accounts, with respect to which a portfolio manager has day-to-day management responsibilities.

Nuveen Asset Management has adopted certain compliance procedures which are designed to address these types of conflicts common among investment managers. However, there is no guarantee that such procedures will detect each and every situation in which a conflict arises.

Item 8(a)(3). FUND MANAGER COMPENSATION

Portfolio manager compensation consists primarily of base pay, an annual cash bonus and long term incentive payments.

Base pay. Base pay is determined based upon an analysis of the portfolio manager’s general performance, experience, and market levels of base pay for such position.

Annual cash bonus.  The Fund’s portfolio managers are eligible for an annual cash bonus based on investment performance, qualitative evaluation and financial performance of Nuveen Asset Management.

A portion of each portfolio manager’s annual cash bonus is based on the Fund’s pre-tax investment performance, generally measured over the past one- and three or five-year periods unless the portfolio manager’s tenure is shorter. Investment performance for the Fund generally is determined by evaluating the Fund’s performance relative to its benchmark(s) and/or Lipper industry peer group.

A portion of the cash bonus is based on a qualitative evaluation made by each portfolio manager’s supervisor taking into consideration a number of factors, including the portfolio manager’s team collaboration, expense management, support of personnel responsible for asset growth, and his or her compliance with Nuveen Asset Management’s policies and procedures.
 
The final factor influencing a portfolio manager’s cash bonus is the financial performance of Nuveen Asset Management based on its operating earnings.

Long-term incentive compensation. Certain key employees of Nuveen Asset Management, including certain portfolio managers, have received profits interests in Nuveen Asset Management which entitle their holders to participate in the firm’s growth over time.

There are generally no differences between the methods used to determine compensation with respect to the Fund and the Other Accounts shown in the table above.
