Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 86% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in credit and credit-related instruments. Credit and credit-related instruments include, but are not limited to:

· domestic and foreign corporate debt obligations, including bonds, notes, debentures, commercial paper and other obligations of corporations to pay interest and repay principal;

· fixed and floating rate loans, including senior loans and secured and unsecured junior loans, in an amount not to exceed 30% of the Fund’s net assets;

· residential and commercial mortgage-backed securities;

· asset-backed securities;

· preferred securities and contingent capital securities (sometimes referred to as “CoCos”) in an aggregate amount not to exceed 20% of the Fund’s net assets;

· interests in senior, mezzanine, and subordinated/equity classes or “tranches” of collateralized loan obligations (“CLOs”);

· U.S. government securities (securities issued or guaranteed by the U.S. government or its agencies or instrumentalities); and

· debt obligations of foreign governments.

The Fund will invest at least 65% of its assets in securities rated lower than investment grade at the time of purchase or in unrated bonds of comparable quality as determined by the Fund’s sub-adviser (securities commonly referred to as “high yield” securities or “junk” bonds). There is no minimum rating requirement and no limitation on the average maturity or average effective duration of securities held by the Fund.

The Fund may invest without limitation in debt obligations of foreign corporations and governments. However, no more than 30% of the Fund’s total assets may be invested in securities of governmental and corporate issuers that are located in emerging market countries.

The Fund may invest in securities that have not been registered under the Securities Act of 1933, as amended (the “Securities Act”) (“restricted securities”), including securities sold in private placement transactions between issuers and their purchasers and securities that meet the requirements of Rule 144A under the Securities Act (“Rule 144A securities”). Rule 144A securities may be resold under certain circumstances only to qualified institutional buyers as defined by the rule.

The Fund may invest in exchange-traded funds (“ETFs”), closed-end funds, and other investment companies (“investment companies”).

The Fund’s sub-adviser makes buy, sell, and hold decisions using a “top-down” approach, which begins with the formulation of the sub-adviser’s general economic outlook. Following this, various sectors and industries are analyzed and selected for investment. Finally, the sub-adviser selects individual securities within these sectors or industries. The sub-adviser also analyzes expected changes to the yield curve under multiple market conditions to help define maturity and duration selection.


Section 1 Fund Summaries	3

The Fund may utilize the following derivatives: options; futures contracts; options on futures contracts; foreign currency contracts; options on foreign currencies; swap agreements, including interest rate swaps, currency swaps, total return swaps and credit default swaps; and options on swap agreements. The Fund may use these derivatives in an attempt to manage market risk, currency risk, credit risk and yield curve risk, to manage the effective maturity or duration of securities in the Fund’s portfolio or for speculative purposes in an effort to increase the Fund’s yield or to enhance returns. The use of a derivative is speculative if the Fund is primarily seeking to enhance returns, rather than offset the risk of other positions.

Principal Risks

The value of your investment in this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund listed below are presented alphabetically to facilitate your ability to find particular risks and compare them with the risks of other funds. The significance of any specific risk to an investment in the Fund will vary over time depending on the composition of the Fund’s portfolio, market conditions and other factors. Each risk summarized below is considered a "principal risk" of investing in the Fund, regardless of the order in which it appears.

Active Management Risk—The Fund’s sub-adviser actively manages the Fund’s investments. Consequently, the Fund is subject to the risk that the investment techniques and risk analyses employed by the Fund’s sub-adviser may not produce the desired results. This could cause the Fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

Call Risk—If, during periods of falling interest rates, an issuer exercises its right to prepay principal on its higher-yielding debt securities held by the Fund, the Fund may have to reinvest in securities with lower yields or higher risk of default, which may adversely impact the Fund’s performance.

Collateralized Loan Obligations Risk—A CLO is an asset-backed security whose underlying collateral is a pool of loans, which may include, among others, domestic and foreign floating rate and fixed rate senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade. In addition to the risks associated with loans and high yield securities, CLOs are subject to the risk that distributions from the collateral may not be adequate to make interest or other payments; the quality of the collateral may decline in value or default; the Fund may invest in tranches of CLOs that are subordinate to other tranches; and the CLO’s manager may perform poorly. CLOs may charge management and other administrative fees, which are in addition to those of the Fund.

Contingent Capital Security Risk—CoCos have loss absorption mechanisms benefitting the issuer built into their terms. Upon the occurrence of a specified trigger or event, CoCos may be subject to automatic conversion into the issuer’s common stock, which likely will have declined in value and which will be subordinate to the issuer’s other classes of securities, or to an automatic write-down of the principal amount of the securities, potentially to zero, which could result in the Fund losing a portion or all of its investment in such securities. CoCos are often rated below investment grade and are subject to the risks of high yield securities.

Credit Risk—Credit risk is the risk that an issuer or other obligated party of a security may be, or perceived (whether by market participants, rating agencies, pricing services or otherwise) to be, unable or unwilling to make dividend, interest and principal payments when due and the related risk that the value of a security may decline because of concerns about the issuer’s ability or willingness to make such payments. Because the Fund invests at least 65% of the value of its assets in high yield securities, the Fund's credit risks are greater than those of funds that buy only investment grade securities.

Credit Spread Risk—Credit spread risk is the risk that credit spreads (i.e., the difference in yield between securities that is due to differences in their credit quality) may increase when the market believes that bonds generally have a greater risk of default. Increasing credit spreads may reduce the market values of the Fund’s debt securities. Credit spreads often increase more for lower rated and unrated securities than for investment grade securities. In addition, when credit spreads increase, reductions in market value will generally be greater for longer-maturity securities.

Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. securities, the value of dividends and interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund’s portfolio.


4	Section 1 Fund Summaries

Fund, its investment adviser or sub-adviser, custodian, transfer agent, distributor or other service provider, a financial intermediary or the issuers of securities held by the Fund to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Fund, its service providers or the issuers of securities held by the Fund may adversely impact the Fund or its shareholders. Additionally, a cybersecurity breach could affect the issuers in which the Fund invests, which may cause the Fund’s investments to lose value.

Derivatives Risk—The use of derivatives involves additional risks and transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivative instruments can be used to acquire or to transfer the risk and returns of a security or other asset without buying or selling the security or asset, and the risks associated with investing in such derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments, including leverage risk, market risk, counterparty risk, liquidity risk, operational risk and legal risk. These instruments may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives can result in losses that greatly exceed the original investment. Derivatives can be highly volatile, illiquid and difficult to value. An over-the-counter derivative transaction between the Fund and a counterparty that is not cleared through a central counterparty also involves the risk that a loss may be sustained as a result of the failure of the counterparty to the contract to make required payments. The payment obligation for a cleared derivative transaction is guaranteed by a central counterparty, which exposes the Fund to the creditworthiness of the central counterparty.

Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets or that are otherwise economically tied to emerging market countries. For example, these countries may have more unstable governments than developed countries and their economies may be based on only a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, which would affect the Fund’s ability to evaluate potential portfolio companies. As a result, there could be less information about issuers in emerging market countries, which could negatively affect the ability of the Fund’s sub-adviser to evaluate local companies or their potential impact on the Fund’s performance. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries. Shareholder claims and regulatory actions that are available in the U.S. may be difficult or impossible to pursue in emerging market countries.

ETF Risk—An ETF is subject to the risks of the underlying securities that it holds. In addition, for index-based ETFs, the performance of an ETF may diverge from the performance of such index (commonly known as tracking error). ETFs are subject to fees and expenses (like management fees and operating expenses) that do not apply to an index, and the Fund will indirectly bear its proportionate share of any such fees and expenses paid by the ETFs in which it invests. Moreover, ETF shares may trade at a premium or discount to their net asset value. As ETFs trade on an exchange, they are subject to the risks of any exchange-traded instrument, including: (i) an active trading market for its shares may not develop or be maintained, (ii) market makers or authorized participants may decide to reduce their role or step away from these activities in times of market stress, (iii) trading of its shares may be halted by the exchange, and (iv) its shares may be delisted from the exchange.

Foreign Investment Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad, as well as armed conflicts and different legal, regulatory and tax environments. Foreign investments may also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent the Fund invests a significant portion of its assets in the securities of companies in a single country or region, it may be more susceptible to adverse conditions affecting that country or region. Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, less public information, less stringent investor protections and less stringent accounting, corporate governance, financial reporting and disclosure standards.

High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, and unrated securities of comparable quality are high risk investments that may cause income and principal losses for the Fund. They generally are considered to be speculative with respect to the ability to pay interest and repay principal, have greater credit risk, are less liquid, are more likely to experience a default and have more volatile prices than investment grade securities.

Illiquid Investments Risk—Certain securities held by the Fund are illiquid investments, which may be difficult to sell for the value at which they are carried, if at all, or at any price within the desired time frame.


Section 1 Fund Summaries	5

Income Risk—The Fund's income could decline during periods of falling interest rates or when the Fund experiences defaults on debt securities or defaults or deferrals on preferred securities it holds.

Interest Rate Risk—Interest rate risk is the risk that the value of the Fund’s fixed-rate securities will decline because of rising interest rates. Changing interest rates may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent that it is exposed to such interest rates. Fixed-rate securities may be subject to a greater risk of rising interest rates than would normally be the case due to the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. Higher periods of inflation could lead to government fiscal policies which raise interest rates. When interest rates change, the values of longer-duration fixed-rate securities usually change more than the values of shorter-duration fixed-rate securities. Conversely, fixed-rate securities with shorter durations or maturities will be less volatile but may provide lower returns than fixed-rate securities with longer durations or maturities. Rising interest rates also may lengthen the duration of securities with call features, since exercise of the call becomes less likely as interest rates rise, which in turn will make the securities more sensitive to changes in interest rates and result in even steeper price declines in the event of further interest rate increases. The Fund is also subject to the risk that the income generated by its investments may not keep pace with inflation.

Loan Risk—The lack of an active trading market for certain loans (including loan participations and assignments) may impair the ability of the Fund to realize full value in the event of the need to sell a loan and may make it difficult to value such loans. Portfolio transactions in loans may settle in as short as seven days but typically can take up to two or three weeks, and in some cases much longer. As a result of these extended settlement periods, the Fund may incur losses if it is required to sell other investments or temporarily borrow to meet its cash needs, including satisfying redemption requests. The risks associated with unsecured loans, which are not backed by a security interest in any specific collateral, are higher than those for comparable loans that are secured by specific collateral. For secured loans, there is a risk that the value of any collateral securing a loan in which the Fund has an interest may decline and that the collateral may not be sufficient to cover the amount owed on the loan. Interests in loans made to finance highly leveraged companies or transactions such as corporate acquisitions may be especially vulnerable to adverse changes in economic or market conditions. Loans may have restrictive covenants limiting the ability of a borrower to further encumber its assets. However, in periods of high demand by lenders like the Fund for loan investments, borrowers may limit these covenants and weaken a lender’s ability to access collateral securing the loan; reprice the credit risk associated with the borrower; and mitigate potential loss. The Fund may experience relatively greater realized or unrealized losses or delays and expenses in enforcing its rights with respect to loans with fewer restrictive covenants. Additionally, loans may not be considered “securities” and, as a result, the Fund may not be entitled to rely on the anti-fraud or other protections of the securities laws. Because junior loans have a lower place in an issuer’s capital structure and may be unsecured, junior loans involve a higher degree of overall risk than senior loans of the issuer. The Fund's investments in floating rate loans that pay interest based on the London Interbank Offered Rate (LIBOR) may experience increased volatility and/or illiquidity during the transition away from LIBOR, which was phased out.

Market Risk—The market value of the Fund’s investments may go up or down, sometimes rapidly or unpredictably and for short or extended periods of time, due to the particular circumstances of individual issuers or due to general conditions impacting issuers more broadly. Global economies and financial markets have become highly interconnected, and thus economic, market or political conditions or events in one country or region might adversely impact the value of the Fund’s investments whether or not the Fund invests in such country or region. Events such as war, terrorism, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies may have a severe negative impact on the global economy, could cause financial markets to experience extreme volatility and losses, and could result in the disruption of trading and the reduction of liquidity in many instruments. Additionally, as inflation increases, the value of the Fund’s assets can decline.

Market Liquidity Risk—Reductions in trading activity or dealer inventories of securities such as bonds and preferred securities, which provide an indication of the ability of financial intermediaries to “make markets” in those securities, have the potential to decrease liquidity and increase price volatility in the markets in which the Fund invests, particularly during periods of economic or market stress. In addition, federal banking regulations may cause certain dealers to reduce their inventories of securities, which may further decrease the Fund’s ability to buy or sell securities. As a result of this decreased liquidity, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on performance. If the Fund needed to sell large blocks of securities to meet shareholder redemption requests or to raise cash, those sales could further reduce the securities’ prices and hurt performance.


6	Section 1 Fund Summaries

Mortgage- and Asset-Backed Securities Risk—These securities generally can be prepaid at any time, and prepayments that occur either more quickly or more slowly than expected can adversely impact the value of such securities. They are also subject to extension risk, which is the risk that rising interest rates could cause mortgages or other obligations underlying the securities to be prepaid more slowly than expected, thereby lengthening the duration of such securities, increasing their sensitivity to interest rate changes and causing their prices to decline. Mortgage-backed securities are particularly sensitive to prepayment risk, given that the term to maturity for mortgage loans is generally substantially longer than the expected lives of those securities. A mortgage-backed security may be negatively affected by the quality of the mortgages underlying such security, the credit quality of its issuer or guarantor, and the nature and structure of its credit support. Mortgage- and asset-backed securities that are not backed by the full faith and credit of the U.S. government are subject to the risk of default on the underlying mortgage, loan or asset, particularly during periods of economic downturn.

Other Investment Companies Risk—When the Fund invests in other investment companies, including ETFs, you bear both your proportionate share of Fund expenses and, indirectly, the expenses of the other investment companies. Furthermore, the Fund is exposed to the risks to which the other investment companies may be subject.

Preferred Security Risk—Preferred securities generally are subordinated to bonds and other debt instruments in a company’s capital structure and therefore will be subject to greater credit risk than those debt instruments. In addition, preferred securities are subject to other risks, such as having no or limited voting rights, being subject to special redemption rights, having distributions deferred or skipped, having floating interest rates or dividends, which may result in a decline in value in a falling interest rate environment, having fixed interest rates or dividends, which may result in a decline in value in a rising interest rate environment, having limited liquidity, changing or unfavorable tax treatments and possibly being issued by companies in heavily regulated industries.

Restricted Securities Risk—The market for restricted securities, including Rule 144A securities, typically is less active than the market for publicly traded securities. Rule 144A securities and other securities exempt from registration under the Securities Act carry the risk that their liquidity may become impaired and the Fund may be unable to dispose of the securities promptly or at current market value.

Sovereign Debt Risk—Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt. This may be due to, for example, cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies.

Unrated Security Risk—Unrated securities determined by the Fund’s sub-adviser to be of comparable quality to rated securities which the Fund may purchase may pay a higher interest rate than such rated securities and be subject to a greater risk of illiquidity or price changes. Less public information is typically available about unrated securities or issuers than rated securities or issuers.

U.S. Government Securities Risk—U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates. Securities issued or guaranteed by U.S. government agencies and instrumentalities are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. government or may be subject to certain limitations. No assurance can be given that the U.S. government will provide financial support to its agencies and instrumentalities if it is not obligated by law to do so, which may increase the risk of loss to the Fund.

Valuation Risk—The sales price the Fund could receive for any particular security may differ from the Fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology. The debt securities in which the Fund invests typically are valued by a pricing service utilizing a range of market-based inputs and assumptions, including price quotations obtained from broker-dealers making markets in such instruments, cash flows and transactions for comparable instruments. There is no assurance that the Fund will be able to buy or sell a portfolio security at the price established by the pricing service, which could result in a gain or loss to the Fund. Pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, often at lower prices than institutional round lot trades. Over certain time periods, such differences could materially impact the performance of the Fund, which may not be sustainable. Alternative pricing services may incorporate different assumptions and inputs into their valuation methodologies, potentially resulting in different values for the same securities. As a result, if the Fund were to change pricing services, or


Section 1 Fund Summaries	7

if the Fund’s pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Fund’s net asset value.

Fund Performance

The following bar chart and table provide some indication of the potential risks of investing in the Fund. The Fund’s performance information prior to July 7, 2020 reflects the Fund’s performance using an investment objective and investment strategies that differed from those currently in place. In view of these changes, the Fund’s performance record prior to this date might be less pertinent for investors considering whether to purchase shares of the Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.nuveen.com/performance or by calling (800) 257-8787.

The bar chart below shows the variability of the Fund’s performance from year to year for Class A shares. The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.

*Class A year-to-date total return as of September 30, 2023 was 6.66%. The performance of the other share classes will differ due to their different expense structures.

During the ten-year period ended December 31, 2022, the Fund’s highest and lowest quarterly returns were 10.49%
and -18.29%, respectively, for the quarters ended June 30, 2020 and March 31, 2020.

The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and an index of funds with similar investment objectives. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans.

Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers had not been in place, returns would have been reduced.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank or financial advisor), the Fund, its distributor or its investment adviser may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other financial intermediary and your salesperson to recommend the Fund over another investment. Ask your financial advisor or visit your financial intermediary’s website for more information.

3 The Fund’s investment adviser has agreed to waive fees and/or reimburse expenses so that the total annual operating expenses of the Fund (excluding 12b-1 distribution and/or service fees, interest expenses, taxes, acquired fund fees and expenses, fees incurred in acquiring and disposing of portfolio securities and extraordinary expenses) do not exceed 0.75% through July 31, 2025 or 1.25% after July 31, 2025 of the average daily net assets of any class of Fund shares. However, because Class R6 shares are not subject to sub-transfer agent and similar fees, the total annual operating expenses for the Class R6 shares will be less than the expense limitation. The expense limitation expiring July 31, 2025 may be terminated or modified prior to that date only with the approval of the Board of Trustees of the Fund. The expense limitation in effect thereafter may be terminated or modified only with the approval of shareholders of the Fund.

Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are at the lesser of Total Annual Fund Operating Expenses or the applicable expense limitation. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets in income producing debt, preferred and convertible securities. Debt securities in which the Fund invests include corporate debt securities, mortgage-backed securities, taxable municipal securities and U.S. government and agency debt securities.

The Fund may invest without limit in below-investment-grade securities, commonly referred to as “high yield” securities or “junk” bonds.

The Fund may invest up to 10% of its net assets in equity securities other than preferred securities, including common stocks, real estate investment trusts (“REITs”), depositary receipts and other types of securities with equity characteristics. The Fund may write covered call options on equity securities to generate additional income. To manage market risk and credit risk in its portfolio, the Fund may make short sales of equity securities and may utilize derivatives, including credit default swap agreements. The Fund’s short sales may equal up to 10% of the value of the Fund’s net assets. The Fund may use all or a portion of the proceeds of its short sales to purchase additional portfolio securities.

The Fund’s investments may include debt securities, preferred units and common units issued by master limited partnerships (“MLPs”), provided that the Fund may not invest more than 10% of its net assets in common units of MLPs.

The Fund may invest up to 50% of its net assets in dollar-denominated securities issued by non-U.S. companies.

The Fund’s sub-adviser employs a rigorous, bottom-up research-focused investment process that seeks to identify undervalued companies with positive risk/reward characteristics and the potential for downside protection. The sub-adviser’s investment process focuses on the attractiveness of a particular security within a company’s capital structure. The sub-adviser may choose to sell securities or reduce positions if it feels that a company no longer possesses favorable risk/reward characteristics, attractive valuations or catalysts, if it identifies better alternatives within a company’s capital structure, or if a company suspends or is projected to suspend its dividend or interest payments.

Principal Risks


12	Section 1 Fund Summaries

Convertible Security Risk—Convertible securities are subject to certain risks of both equity and debt securities. The value of convertible securities may decline in response to such factors as rising interest rates and fluctuations in the market price of the common stock underlying the convertible securities.

Covered Call Risk—Covered call risk includes the risk that the Fund, as a writer of covered call options, will forgo during an option’s life the opportunity to profit from increases in the market value of the security covering the call option.

Currency Risk—Even though the non-U.S. securities held by the Fund are traded in U.S. dollars, their prices are typically indirectly influenced by currency fluctuations. Changes in currency exchange rates may affect the Fund’s net asset value, the value of dividends and interest earned, gains or losses realized on the sale of securities, and derivative transactions tied to such securities.

Cybersecurity Risk—Cybersecurity risk is the risk of an unauthorized breach and access to Fund assets, customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, its investment adviser or sub-adviser, custodian, transfer agent, distributor or other service provider, a financial intermediary or the issuers of securities held by the Fund to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Fund, its service providers or the issuers of securities held by the Fund may adversely impact the Fund or its shareholders. Additionally, a cybersecurity breach could affect the issuers in which the Fund invests, which may cause the Fund’s investments to lose value.

Equity Security Risk—Equity securities in the Fund’s portfolio may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular country, company, industry, or sector of the market. From time to time, the Fund may invest a significant portion of its assets in companies in one or more related sectors or industries which would make the Fund more vulnerable to adverse developments affecting such sectors or industries.


Section 1 Fund Summaries	13

Master Limited Partnership Risk—Investments in common units of MLPs involve risks that differ from investments in common stock, including risks related to limited control and limited rights to vote. An investment in an MLP also exposes the Fund to the legal and tax risks associated with investing in partnerships. MLPs may have limited financial resources, their securities may be relatively illiquid, and they may be subject to more erratic price movements because of the underlying assets they hold.

Mortgage-Backed Securities Risk—These securities generally can be prepaid at any time, and prepayments that occur either more quickly or more slowly than expected can adversely impact the value of such securities. They are also subject to extension risk, which is the risk that rising interest rates could cause mortgages underlying the securities to be prepaid more slowly than expected, thereby lengthening the duration of such securities, increasing their sensitivity to interest rate changes and causing their prices to decline. Mortgage-backed securities are particularly sensitive to prepayment risk, given that the term to maturity for mortgage loans is generally substantially longer than the expected lives of those securities. A mortgage-backed security may be negatively affected by the quality of the mortgages underlying such security, the credit quality of its issuer or guarantor, and the nature and structure of its credit support. Mortgage-backed securities that are not backed by the full faith and credit of the U.S. government are subject to the risk of default on the underlying mortgage, particularly during periods of economic downturn.


14	Section 1 Fund Summaries

Municipal Securities Risk—The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers. The amount of public information available about municipal bonds is generally less than for certain corporate equities or bonds, meaning that the investment performance of the Fund may be more dependent on the analytical abilities of the Fund’s sub-adviser than funds that invest in stock or other corporate investments.

Short Sales Risk—Short sales involve the sale of a security the Fund has borrowed, with the expectation that the security will underperform the market. Short sales expose the Fund to the risk that it will be required to buy the security sold short (also known as “covering” the short position) at a time when the security has appreciated in value, thus resulting in a loss to the Fund. Although the gain is limited by the price at which the security was sold short, the loss is potentially unlimited. To the extent the Fund invests the proceeds received from selling securities short in additional portfolio securities, the Fund is engaging in a form of leverage. The use of leverage may increase the Fund’s exposure to long positions and make any change in the Fund’s net asset value greater than it would be without the use of leverage. This could result in increased volatility of returns. The use of short sales may also cause the Fund to have higher expenses than other funds.

Portfolio Turnover

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in floating rate securities. Floating rate securities are defined to include floating rate loans, other floating rate debt securities including corporate debt securities and U.S. government securities, money market securities and shares of money market and short-term bond funds. The Fund may invest up to 20% of its net assets in other securities, which would primarily be fixed rate debt securities of any maturity, convertible securities and equity securities received as a result of the restructuring of an issuer’s debt. A substantial portion of the Fund’s assets generally will be invested in securities rated below investment grade or, if unrated, deemed by the Fund’s portfolio managers to be of comparable quality. Below investment-grade securities are commonly referred to as “high yield” securities or “junk” bonds. The Fund invests both in securities issued by U.S. companies and in U.S. dollar-denominated securities issued by non-U.S. companies that are traded over-the-counter or listed on an exchange. Under normal market conditions, the average effective duration of the Fund’s portfolio will not be longer than one year. Effective duration is an estimate of how much the value of a debt security will change with a given change in interest rates.

The Fund may utilize the following derivatives: options; futures contracts; options on futures contracts; swap agreements, including interest rate swaps, total return swaps, and credit default swaps; and options on swap agreements. The Fund may use these derivatives in an attempt to manage market risk, credit risk and yield curve risk, to manage the effective maturity or duration of securities in the Fund’s portfolio, including the use of interest rate derivatives to convert fixed-rate securities to floating rate securities, or for speculative purposes in an effort to increase the Fund’s yield or to enhance returns. The use of a derivative is speculative if the Fund is primarily seeking to enhance returns, rather than offset the risk of other positions.

The Fund’s sub-adviser bases its investment process on fundamental, bottom-up credit analysis. Analysts assess sector dynamics, company business models and asset quality. Inherent in the sub-adviser’s credit analysis process is the evaluation of potential upside and downside to any credit. As such, the sub-adviser concentrates its efforts on sectors where there is sufficient transparency to assess the downside risk and where firms have assets to support meaningful recovery in case of default. In its focus on downside protection, the sub-adviser favors opportunities where valuations can be quantified and risks assessed.

Principal Risks


20	Section 1 Fund Summaries


Section 1 Fund Summaries	21

Income Risk—The Fund's income could decline during periods of falling interest rates or when the Fund experiences defaults on debt securities it holds. Income risk is generally higher for limited-term bonds so investors may experience a fluctuation in the monthly income from the Fund.

Interest Rate Risk—Interest rate risk is the risk that the value of the Fund’s fixed-rate securities will decline because of rising interest rates. Changing interest rates may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent that it is exposed to such interest rates. Fixed-rate securities may be subject to a greater risk of rising interest rates than would normally be the case due to the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. Higher periods of inflation could lead to government fiscal policies which raise interest rates. When interest rates change, the values of longer-duration fixed-rate securities usually change more than the values of shorter-duration fixed-rate securities. Conversely, fixed-rate securities with shorter durations or maturities will be less volatile but may provide lower returns than fixed-rate securities with longer durations or maturities. Rising interest rates also may lengthen the duration of securities with call features, since exercise of the call becomes less likely as interest rates rise, which in turn will make the securities more sensitive to changes in interest rates and result in even steeper price declines in the event of further interest rate increases. Because the Fund primarily invests in floating rate loans, interest rate risk may be reduced. However, floating rate loans are still subject to interest rate risk, and their values may decrease, if their interest rates do not reset as quickly as a general rise in interest rates. The Fund is also subject to the risk that the income generated by its investments may not keep pace with inflation.

Loan Risk—The lack of an active trading market for certain loans (including loan participations and assignments) may impair the ability of the Fund to realize full value in the event of the need to sell a loan and may make it difficult to value such loans. Portfolio transactions in loans may settle in as short as seven days but typically can take up to two or three weeks, and in some cases much longer. As a result of these extended settlement periods, the Fund may incur losses if it is required to sell other investments or temporarily borrow to meet its cash needs, including satisfying redemption requests. The risks associated with unsecured loans, which are not backed by a security interest in any specific collateral, are higher than those for comparable loans that are secured by specific collateral. For secured loans, there is a risk that the value of any collateral securing a loan in which the Fund has an interest may decline and that the collateral may not be sufficient to cover the amount owed on the loan. Interests in loans made to finance highly leveraged companies or transactions such as corporate acquisitions may be especially vulnerable to adverse changes in economic or market conditions. Loans may have restrictive covenants limiting the ability of a borrower to further encumber its assets. However, in periods of high demand by lenders like the Fund for loan investments, borrowers may limit these covenants and weaken a lender’s ability to access collateral securing the loan; reprice the credit risk associated with the borrower; and mitigate potential loss. The Fund may experience relatively greater realized or unrealized losses or delays and expenses in enforcing its rights with respect to loans with fewer restrictive covenants. Additionally, loans may not be considered “securities” and, as a result, the Fund may not be entitled to rely on the anti-fraud or other protections of the securities laws. Because junior loans have a lower place in an issuer’s capital structure and may be unsecured, junior loans involve a higher degree of overall risk than senior loans of the issuer. The Fund’s investments in floating rate loans that pay interest based on the London Interbank Offered Rate (LIBOR) may experience increased volatility and/or illiquidity during the transition away from LIBOR, which was phased out.


22	Section 1 Fund Summaries

blocks of securities to meet shareholder redemption requests or to raise cash, those sales could further reduce the securities’ prices and hurt performance.

Money Market Fund Risk—An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the FDIC or any other government agency. It is possible for the Fund to lose money by investing in money market funds. If the liquidity of a money market fund’s portfolio deteriorates below certain levels, the money market fund may suspend redemptions or impose a fee of up to 2% on amounts the Fund redeems from the money market fund. These measures may result in an investment loss or prohibit the Fund from redeeming shares. Additionally, the Fund indirectly bears the fees and expenses of any money market funds in which it invests.

Nuveen High Yield Income Fund

Investment Objective

The investment objective of the Fund is to seek current income and capital appreciation.

Fees and Expenses of the Fund

The following tables describe the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund or in other Nuveen Mutual Funds.

4 The Fund’s investment adviser has agreed to waive fees and/or reimburse expenses so that the total annual operating expenses of the Fund (excluding 12b-1 distribution and/or service fees, interest expenses, taxes, acquired fund fees and expenses, fees incurred in acquiring and disposing of portfolio securities and extraordinary expenses) do not exceed 0.79% through July 31, 2025 or 1.35% after July 31, 2025 of the average daily net assets of any class of Fund shares. However, because Class R6 shares are not subject to sub-transfer agent and similar fees, the total annual operating expenses for the Class R6 shares will be less than the expense limitation. The expense limitation expiring July 31, 2025 may be terminated or modified prior to that date only with the approval of the Board of Trustees of the Fund. The expense limitation in effect thereafter may be terminated or modified only with the approval of shareholders of the Fund.

Portfolio Turnover

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in debt instruments (e.g., bonds and loans) rated below investment grade or, if unrated, deemed by the Fund’s portfolio managers to be of comparable quality. Below investment-grade securities are commonly referred to as “high yield” securities or “junk” bonds. The Fund may invest up to 30% of its net assets in loans. The Fund invests both in debt issued by U.S. companies and in U.S. dollar-denominated debt issued by non-U.S. companies that is traded over-the-counter or listed on an exchange.

The Fund may utilize the following derivatives: options; futures contracts; options on futures contracts; swap agreements, including interest rate swaps, total return swaps, and credit default swaps; and options on swap agreements. The Fund may use these derivatives in an attempt to manage market risk, credit risk and yield curve risk, to manage the effective maturity or duration of securities in the Fund’s portfolio or for speculative purposes in an effort to increase the Fund’s yield or to enhance returns. The use of a derivative is speculative if the Fund is primarily seeking to enhance returns, rather than offset the risk of other positions.

The Fund’s sub-adviser bases its investment process on fundamental, bottom-up credit analysis. Analysts assess sector dynamics, company business models and asset quality. Specific recommendations are based on an analysis of the relative value of the various types of debt within a company’s capital structure. Inherent in the sub-adviser’s credit analysis process is the evaluation of potential upside and downside to any credit. As such, the sub-adviser concentrates its efforts on sectors where there is sufficient transparency to assess the downside risk and where firms have assets to support meaningful recovery in case of default. In its focus on downside protection, the sub-adviser favors opportunities where valuations can be quantified and risks assessed.

Principal Risks


Section 1 Fund Summaries	27

Credit Risk—Credit risk is the risk that an issuer or other obligated party of a debt security may be, or perceived (whether by market participants, rating agencies, pricing services or otherwise) to be, unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer’s ability or willingness to make such payments. Because the Fund invests at least 80% of the value of its assets in high yield securities, the Fund’s credit risks are greater than those of funds that buy only investment grade securities.

Currency Risk—Even though the non-U.S. securities held by the Fund are traded in U.S. dollars, their prices are typically indirectly influenced by currency fluctuations. Changes in currency exchange rates may affect the Fund’s net asset value, interest earned, gains or losses realized on the sale of securities, and derivative transactions tied to such securities.

Frequent Trading Risk—The Fund's portfolio turnover rate may exceed 100%. Frequent trading of portfolio securities may produce capital gains, which are taxable to shareholders when distributed. Frequent trading may also increase the amount of commissions or mark-ups to broker-dealers that the Fund pays when it buys and sells securities, which may detract from the Fund’s performance.


28	Section 1 Fund Summaries

Income Risk—The Fund's income could decline during periods of falling interest rates or when the Fund experiences defaults on debt securities it holds.

Section 1 Fund Summaries	33

Portfolio Turnover

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in preferred securities and other income producing securities. The Fund may invest in all types of preferred securities, including both perpetual preferred securities and hybrid securities. Perpetual preferred securities are generally equity securities of the issuer that have priority over the issuer’s common shares as to the payment of dividends (i.e., the issuer cannot pay dividends on its common shares until the dividends on the preferred shares are current) and as to the payout of proceeds of a bankruptcy or other liquidation, but are subordinate to an issuer’s senior debt and junior debt as to both types of payments. Additionally, in a bankruptcy or other liquidation, perpetual preferred securities are generally subordinate to an issuer’s trade creditors and other general obligations. Perpetual preferred securities typically have a fixed liquidation (or “par”) value.

The term “preferred securities” also includes hybrid securities and other types of preferred securities that do not have the features described above. Preferred securities that are hybrid securities often behave similarly to investments in perpetual preferred securities and are regarded by market investors as being part of the preferred securities market. Such hybrid securities possess varying combinations of features of both debt and perpetual preferred securities and as such they may constitute senior debt, junior debt or preferred shares in an issuer’s capital structure.

The term “preferred securities” also includes certain forms of debt that are regarded by the investment marketplace to be part of the broader preferred securities market. Among these preferred securities are certain exchange-listed debt issues that historically have several attributes, including trading and investment performance characteristics, in common with exchange-listed perpetual preferred securities and hybrid securities. Generally, these types of preferred securities are senior debt in the capital structure of an issuer.

The Fund may also invest in income producing securities that are not preferred securities. These include contingent capital securities (sometimes referred to as “CoCos”), which are hybrid securities, issued primarily by non-U.S. financial institutions, that have loss absorption mechanisms benefitting the issuer built into their terms. These loss absorption mechanisms may include automatic conversion into the issuer’s common stock or an automatic write down of the security’s principal amount upon the occurrence of a specified trigger or event. In addition, although the Fund will invest primarily in preferred securities and CoCos, it may invest up to 20% of its net assets, in the aggregate, in corporate debt securities, U.S. government securities (including securities issued or guaranteed by U.S. government agencies and instrumentalities) and taxable municipal securities.

The Fund may also invest in preferred securities or CoCos that are convertible into common stock.

The Fund normally invests at least 50% of its net assets in securities rated investment grade (BBB/Baa or higher) at the time of purchase by at least one independent rating agency and unrated securities judged to be of comparable quality by the Fund’s portfolio managers. The Fund may invest up to 50% of its net assets in securities rated below investment grade (BB/Ba or lower) or unrated securities judged to be of comparable quality by the Fund’s portfolio managers at the time of purchase, which are commonly referred to as “high yield” securities or “junk” bonds. The Fund may also invest in U.S. dollar-denominated securities issued by non-U.S. companies.

The Fund intends to invest at least 25% of its assets in the securities of companies principally engaged in financial services.

The Fund’s sub-adviser considers several factors in constructing the Fund’s portfolio of preferred securities, including credit risk, diversification, preferred sub-market analysis, call protection and yield curve analysis. From this analysis, the


34	Section 1 Fund Summaries

Fund’s sub-adviser builds a portfolio of securities that it believes offers the most attractive mix of value relative to securities with similar credit ratings, current income and call protection.

Principal Risks

Currency Risk—Even though the non-U.S. securities held by the Fund are traded in U.S. dollars, their prices are typically indirectly influenced by currency fluctuations. Changes in currency exchange rates may affect the Fund’s net asset value, the value of dividends and interest earned, and gains or losses realized on the sale of securities.

Financial Services Sector Risk—The Fund's policy to concentrate in financial services companies makes the Fund more susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are particularly sensitive to the adverse effects of economic recession; changes in government regulation; the availability of capital; volatile interest rates; and the health of the commercial and residential real estate markets.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets in income producing securities, including:

· U.S. government securities (securities issued or guaranteed by the U.S. government or its agencies or instrumentalities);

· residential and commercial mortgage-backed securities;

· asset-backed securities;

· domestic and foreign corporate debt obligations, including obligations issued by special-purpose entities that are backed by corporate debt obligations;

· preferred securities and contingent capital securities (sometimes referred to as “CoCos”) in an aggregate amount not to exceed 20% of the Fund’s net assets;

· fixed and floating rate loans, including senior loans and secured and unsecured junior loans, in an amount not to exceed 20% of the Fund’s net assets;

· debt obligations of foreign governments; and

· municipal securities in an amount not to exceed 20% of the Fund’s net assets.

The Fund may invest up to 30% of its total assets in non-U.S. dollar denominated debt obligations of foreign corporations and governments, including debt obligations issued by governmental and corporate issuers that are located in emerging market countries. The Fund may invest without limitation in U.S. dollar denominated securities of foreign issuers.

The Fund may invest up to 50% of its total assets in securities rated lower than investment grade or unrated securities of comparable quality as determined by the Fund’s sub-adviser (securities commonly referred to as “high yield” securities or “junk” bonds). The Fund will not invest in securities rated lower than CCC at the time of purchase or in unrated securities of comparable quality as determined by the Fund’s sub-adviser. If the rating of a security is reduced or the credit quality of an unrated security declines after purchase, the Fund is not required to sell the security, but may consider doing so. Unrated securities will not exceed 25% of the Fund’s total assets.

Under normal market conditions, the Fund attempts to maintain a weighted average effective maturity for its portfolio securities of fifteen years or less and an average effective duration of three to eight years. The Fund’s weighted average effective maturity and average effective duration are measures of how the value of the Fund’s shares may react to interest rate changes.

To generate additional income, the Fund may invest up to 25% of its total assets in dollar roll transactions. In a dollar roll transaction, the Fund sells mortgage-backed securities for delivery in the current month while contracting with the same party to repurchase similar securities at a future date.


42	Section 1 Fund Summaries

The Fund may utilize the following derivatives: options; futures contracts; options on futures contracts; interest rate caps, collars, and floors; foreign currency contracts; options on foreign currencies; swap agreements, including swap agreements on interest rates, currency rates, security indexes and specific securities, and credit default swap agreements; and options on the foregoing types of swap agreements. The Fund may enter into standardized derivatives contracts traded on domestic or foreign securities exchanges, boards of trade, or similar entities, and non-standardized derivatives contracts traded in the over-the-counter market. The Fund may use these derivatives in an attempt to manage market risk, currency risk, credit risk and yield curve risk, to manage the effective maturity or duration of securities in the Fund’s portfolio or for speculative purposes in an effort to increase the Fund’s yield or to enhance returns. The Fund may also use derivatives to gain exposure to non-dollar denominated securities markets to the extent it does not do so through direct investments. The use of a derivative is speculative if the Fund is primarily seeking to enhance returns, rather than offset the risk of other positions. The Fund may not use any derivative to gain exposure to a security or type of security that it would be prohibited by its investment restrictions from purchasing directly.

Principal Risks


Section 1 Fund Summaries	43

issuers of securities held by the Fund may adversely impact the Fund or its shareholders. Additionally, a cybersecurity breach could affect the issuers in which the Fund invests, which may cause the Fund’s investments to lose value.

Dollar Roll Transaction Risk—The use of dollar rolls can increase the volatility of the Fund’s share price, and it may have an adverse impact on performance unless the sub-adviser correctly predicts mortgage prepayments and interest rates. These transactions are subject to the risk that the counterparty to the transaction may not or be unable to perform in accordance with the terms of the instrument.


44	Section 1 Fund Summaries

securities with longer durations or maturities. Rising interest rates also may lengthen the duration of securities with call features, since exercise of the call becomes less likely as interest rates rise, which in turn will make the securities more sensitive to changes in interest rates and result in even steeper price declines in the event of further interest rate increases. The Fund is also subject to the risk that the income generated by its investments may not keep pace with inflation.

Management Fees

The management fee schedule for each Fund consists of two components: a Fund-level fee, based only on the amount of assets within a Fund, and a complex-level fee, based on the aggregate amount of all eligible fund assets managed by Nuveen Fund Advisors.

The annual Fund-level fee, payable monthly, is based upon the average daily net assets of each Fund as follows:


Average Daily Net Assets	Nuveen Credit Income Fund	Nuveen Flexible Income Fund	Nuveen Floating Rate Income Fund
For the first $125 million	0.4000%	0.5500%	0.4500%
For the next $125 million	0.3875%	0.5375%	0.4375%
For the next $250 million	0.3750%	0.5250%	0.4250%
For the next $500 million	0.3625%	0.5125%	0.4125%
For the next $1 billion	0.3500%	0.5000%	0.4000%
For the next $3 billion	0.3250%	0.4750%	0.3750%
For the next $5 billion	0.3000%	0.4500%	0.3500%
For net assets over $10 billion	0.2875%	0.4375%	0.3375%


52	Section 2 How We Manage Your Money


Average Daily Net Assets	Nuveen High Yield Income Fund	Nuveen Preferred Securities and Income Fund	Nuveen Strategic Income Fund
For the first $125 million	0.4500%	0.5500%	0.3600%
For the next $125 million	0.4375%	0.5375%	0.3475%
For the next $250 million	0.4250%	0.5250%	0.3350%
For the next $500 million	0.4125%	0.5125%	0.3225%
For the next $1 billion	0.4000%	0.5000%	0.3100%
For the next $3 billion	0.3750%	0.4750%	0.2850%
For the next $5 billion	0.3500%	0.4500%	0.2600%
For net assets over $10 billion	0.3375%	0.4375%	0.2475%

The overall complex-level fee begins at a maximum rate of 0.2000% of each Fund’s average daily net assets, based upon complex-level assets of $55 billion, with breakpoints for eligible assets above that level. Therefore, the maximum management fee rate for each Fund is the Fund-level fee plus 0.2000%. The complex-level fee rate for Nuveen Credit Income Fund and Nuveen Strategic Income Fund is determined by taking the current overall complex-level fee rate, which is based on the aggregate amount of the “eligible assets” of all Nuveen funds, and making, as appropriate, an upward adjustment to that rate based upon the percentage of the particular Fund’s assets that are not “eligible assets.” The complex-level fee for Nuveen Flexible Income Fund, Nuveen Floating Rate Income Fund, Nuveen High Yield Income Fund and Nuveen Preferred Securities and Income Fund is the overall complex-level fee rate. As of September 30, 2023, the Funds’ effective complex-level fee rates were as follows:


	Complex-Level Fee Rate
Nuveen Credit Income Fund	0.2000%
Nuveen Flexible Income Fund	0.1611%
Nuveen Floating Rate Income Fund	0.1611%
Nuveen High Yield Income Fund	0.1611%
Nuveen Preferred Securities and Income Fund	0.1611%
Nuveen Strategic Income Fund	0.1949%

For the most recent fiscal year, each Fund paid Nuveen Fund Advisors the following management fees (net of fee waivers and expense reimbursements, where applicable) as a percentage of average daily net assets:


Nuveen Credit Income Fund	0.38%
Nuveen Flexible Income Fund	0.61%
Nuveen Floating Rate Income Fund	0.57%
Nuveen High Yield Income Fund	0.52%
Nuveen Preferred Securities and Income Fund	0.65%
Nuveen Strategic Income Fund	0.41%

Nuveen Fund Advisors has agreed to waive fees and/or reimburse expenses so that the total annual operating expenses (excluding 12b-1 distribution and/or service fees, interest expenses, taxes, acquired fund fees and expenses, fees incurred in acquiring and disposing of portfolio securities and extraordinary expenses) for the Funds do not exceed the percentages of the average daily net assets listed below of any class of Fund shares. However, because Class R6 shares are not subject to sub-transfer agent and similar fees, the total annual operating expenses for the Class R6 shares will be less than the expense limitation.


Section 2 How We Manage Your Money	53


Nuveen Credit Income Fund	0.75% through July 31, 2025
Nuveen Flexible Income Fund	0.75% through July 31, 2025 and 1.25% thereafter
Nuveen Floating Rate Income Fund	0.85% through July 31, 2025 and 1.10% thereafter
Nuveen High Yield Income Fund	0.79% through July 31, 2025 and 1.35% thereafter
Nuveen Preferred Securities and Income Fund	1.25%
Nuveen Strategic Income Fund	0.59% through July 31, 2025

The expense limitations expiring July 31, 2025 may be terminated or modified prior to that date only with the approval of the Board of Directors/Trustees of the Funds. The expense limitations in effect thereafter may be terminated or modified only with the approval of shareholders of the Funds.

Information regarding the Board of Directors'/Trustees’ approval of the investment management agreements is available in the Funds’ annual report for the fiscal year ended August 31, 2023.

More About Our Investment Strategies

The investment objectives of Nuveen Credit Income Fund and Nuveen Strategic Income Fund, which are described in the "Fund Summaries" section, may be changed without shareholder approval. If the investment objective of Nuveen Credit Income Fund or Nuveen Strategic Income Fund changes, you will be notified at least 60 days in advance. The investment objectives of Nuveen Flexible Income Fund, Nuveen Floating Rate Income Fund, Nuveen High Yield Income Fund and Nuveen Preferred Securities and Income Fund, which are described in the "Fund Summaries" section, may not be changed without shareholder approval.

Certain Funds have adopted a non-fundamental investment policy (a “Name Policy”). Nuveen Credit Income Fund, under normal circumstances, will invest at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in credit and credit-related instruments. Nuveen Floating Rate Income Fund, under normal market conditions, will invest at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in floating rate securities. Floating rate securities are defined to include floating rate loans, other floating rate debt securities, money market securities and shares of money market and short-term bond funds. Nuveen High Yield Income Fund, under normal circumstances, will invest at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in debt instruments (e.g., bonds and loans) rated below investment grade or, if unrated, deemed by the Fund’s portfolio managers to be of comparable quality. The Funds will consider both direct investments and indirect investments (e.g., investments in other investment companies, derivatives and synthetic instruments with economic characteristics similar to the direct investments that meet the Name Policy) when determining compliance with the Name Policy. For purposes of the Name Policy, a Fund will value eligible derivatives at fair value or market value instead of notional value. As a result of having a Name Policy, each Fund must provide shareholders with a notice at least 60 days prior to any change of the Fund's Name Policy.

The Funds’ investment policies may be changed by the Board of Directors/Trustees without shareholder approval unless otherwise noted in this prospectus or the statement of additional information.

The Funds’ principal investment strategies are discussed in the “Fund Summaries” section. These are the strategies that the Funds’ investment adviser and sub-adviser believe are most likely to be important in trying to achieve the Funds’ investment objectives. This section provides more information about these strategies, as well as


54	Section 2 How We Manage Your Money

information about some additional strategies that the Funds’ sub-adviser uses, or may use, to achieve the Funds’ objectives. You should be aware that each Fund may also use strategies and invest in securities that are not described in this prospectus, but that are described in the statement of additional information. For a copy of the statement of additional information, call Nuveen Funds at (800) 257-8787 or visit Nuveen’s website at www.nuveen.com.

Corporate Debt Securities

As a principal investment strategy, the Funds may invest in corporate debt securities issued by companies of all kinds, including those with small-, mid- and large-capitalizations. Corporate debt securities are fixed income securities issued by businesses to finance their operations. Notes, bonds, debentures and commercial paper are the most common types of corporate debt securities, with the primary difference being their maturities and secured or unsecured status. Commercial paper has the shortest term and is usually unsecured. Corporate debt securities may be rated investment-grade or below investment-grade and may carry fixed or floating rates of interest.

Government Securities

The Funds may invest in government securities. U.S. government securities include U.S. Treasury obligations and securities issued or guaranteed by various agencies of the U.S. government, or by various instrumentalities which have been established or sponsored by the U.S. government. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government. Securities issued or guaranteed by federal agencies and U.S. government sponsored instrumentalities may or may not be backed by the full faith and credit of the U.S. government. As a principal investment strategy, Nuveen Credit Income Fund and Nuveen Strategic Income Fund may invest in non-U.S. government securities. Non-U.S. government securities include debt obligations issued or guaranteed by governments (including states, provinces or municipalities) of countries other than the United States, or by their agencies, authorities, or instrumentalities, and debt obligations issued or guaranteed by supranational entities organized or supported by several national governments.

Municipal Securities

As a principal investment strategy, Nuveen Flexible Income Fund, Nuveen Preferred Securities and Income Fund and Nuveen Strategic Income Fund may invest in municipal bonds. States, local governments and municipalities and other issuing authorities issue municipal bonds to raise money for various public purposes such as building public facilities, refinancing outstanding obligations and financing general operating expenses. These bonds include general obligation bonds, which are backed by the full faith and credit of the issuer and may be repaid from any revenue source, and revenue bonds, which may be repaid only from the revenue of a specific facility or source. Municipal bonds issued to finance activities with a broad public purpose are generally exempt from federal income tax. Taxable municipal bonds, however, are issued to finance activities with less significant benefits to the public, such as the construction of sports facilities, and as such the interest paid to holders of such bonds is taxable as ordinary income. Many taxable municipal bonds offer yields comparable to those of other taxable bonds, such as corporate and agency bonds. Taxable municipal bonds may be rated investment-grade or below investment-grade and pay interest based on fixed or floating rate coupons. Maturities may range from long-term to short-term.

Loans

As a principal investment strategy, Nuveen Credit Income Fund, Nuveen Floating Rate Income Fund, Nuveen High Yield Income Fund and Nuveen Strategic Income Fund may


Section 2 How We Manage Your Money	55

invest in loans, including senior secured loans, unsecured and/or subordinated loans, loan participations and unfunded contracts. These loans are typically made by or issued to corporations primarily to finance acquisitions, refinance existing debt, support organic growth, or pay out dividends, and are typically originated by large banks and are then syndicated out to institutional investors as well as to other banks. Loans typically bear interest at a floating rate, although some loans pay a fixed rate. Floating rate loans have interest rates that reset periodically, typically monthly or quarterly. The interest rates on floating rate loans are generally based on a percentage above the London Interbank Offered Rate (LIBOR) (which was phased out), a U.S. bank’s prime or base rate, the overnight federal funds rate or another rate. See “What the Risks Are – Principal Risks – Loan risk” below for information about the phase out of LIBOR and its impact on certain floating rate loans and other instruments in which the Funds may invest. Due to their lower place in the borrower’s capital structure, unsecured and/or subordinated loans involve a higher degree of overall risk than senior bank loans of the same borrower. Loan participations are loans that are shared by a group of lenders. Unfunded commitments are contractual obligations by lenders (such as a Fund) to loan an amount in the future or that is due to be contractually funded in the future.

Loans may have restrictive covenants limiting the ability of a borrower to further encumber its assets. The types of covenants included in loan agreements generally vary depending on market conditions, the creditworthiness of the borrower, the nature of the collateral securing the loan and other factors. Such restrictive covenants normally allow for early intervention and proactive mitigation of credit risk by providing lenders with the ability to (1) intervene and either prevent or restrict actions that may potentially compromise the borrower’s ability to repay the loan and/or (2) obtain concessions from the borrower in exchange for waiving or amending a particular covenant. Loans with fewer or weaker restrictive covenants may limit a Fund’s ability to intervene or obtain additional concessions from borrowers.

High Yield Debt Securities

As a principal investment strategy, the Funds may invest in debt securities rated below investment grade or unrated securities deemed by the Funds’ sub-adviser to be of comparable quality. Debt securities rated below investment grade are commonly referred to as “high yield” securities or “junk” bonds. These types of bonds are typically issued by companies without long track records of sales and earnings, or by issuers that have questionable credit strength. High yield and comparable unrated debt securities: (a) will likely have some quality and protective characteristics that, in the judgment of the rating agency evaluating the instrument, are outweighed by large uncertainties or major risk exposures to adverse conditions; and (b) are predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal in accordance with the terms of the obligation.

Asset-Backed Securities

As a principal investment strategy, Nuveen Credit Income Fund and Nuveen Strategic Income Fund may invest in asset-backed securities. Asset-backed securities are securities issued by trusts and special purpose entities that are backed by pools of assets, such as automobile loans and credit-card receivables, and which pass through the payments on the underlying obligations to the security holders (less servicing fees paid to the originator or fees for any credit enhancement). Typically, the originator of the loan or accounts receivable transfers it to a specially created trust, which repackages it as securities with a minimum denomination and a specific term. The securities are then privately placed or publicly offered.


56	Section 2 How We Manage Your Money

Mortgage-Backed Securities

As a principal investment strategy, Nuveen Credit Income Fund, Nuveen Flexible Income Fund and Nuveen Strategic Income Fund may invest in mortgage-backed securities. A mortgage-backed security is a type of pass-through security backed by an ownership interest in a pool of mortgage loans. Mortgage-backed securities may be guaranteed by, or secured by collateral that is guaranteed by, the U.S. government, its agencies, instrumentalities or sponsored corporations. Mortgage-backed securities may also be privately issued; these include commercial mortgage-backed securities.

Preferred Securities

As a principal investment strategy, Nuveen Credit Income Fund, Nuveen Flexible Income Fund, Nuveen Preferred Securities and Income Fund and Nuveen Strategic Income Fund may invest in all types of preferred securities, including both perpetual preferred securities and hybrid securities. Perpetual preferred securities are generally equity securities of the issuer that have priority over the issuer’s common shares as to the payment of dividends (i.e., the issuer cannot pay dividends on its common shares until the dividends on the preferred shares are current) and as to the payout of proceeds of a bankruptcy or other liquidation, but are subordinate to an issuer’s senior debt and junior debt as to both types of payments. Additionally, in a bankruptcy or other liquidation, perpetual preferred securities are generally subordinate to an issuer’s trade creditors and other general obligations. Perpetual preferred securities typically have a fixed liquidation (or “par”) value.

As a general matter, dividend or interest payments on preferred securities may be cumulative or non-cumulative and may be deferred (in the case of cumulative payments) or skipped (in the case of non-cumulative payments) at the option of the issuer.

Generally, preferred security holders have no voting rights with respect to the issuing company, except in some cases voting rights may arise if the issuer fails to pay the preferred share dividends or if a declaration of default occurs and is continuing.

Preferred securities may either trade over-the-counter (“OTC”) or trade on an exchange. Preferred securities can be structured differently for retail and institutional investors, and a Fund may invest in preferred securities of either structure. The retail segment is typified by $25 par value exchange-traded securities, which trade on exchanges such as the New York Stock Exchange (“NYSE”) and the institutional segment is typified by $1,000 par value OTC securities. Typically, most $25 par value exchange-traded securities have fixed-rate coupon structures, while the institutional segment of $1,000 par securities are variable-rate securities. Both $25 and $1,000 par value securities are


Section 2 How We Manage Your Money	57

often callable at par value, typically at least five years after their original issuance date (i.e., the issuer has the right to call in or redeem the preferred security at a pre-set price after a specified date).

Convertible Securities

As a principal investment strategy, Nuveen Flexible Income Fund, Nuveen Floating Rate Income Fund and Nuveen Preferred Securities and Income Fund may invest in convertible securities, which are hybrid securities that combine the investment characteristics of bonds and common stocks. Convertible securities typically consist of debt securities or preferred securities that may be converted within a specified period of time (typically for the entire life of the security) into a certain amount of common stock or other equity security of the same or a different issuer at a predetermined price. They also include debt securities with warrants or common stock attached and derivatives combining the features of debt securities and equity securities. Convertible securities entitle the holder to receive interest paid or accrued on debt securities, or dividends paid or accrued on preferred securities, until the securities mature or are redeemed, converted or exchanged.

Contingent Capital Securities

As a principal investment strategy, Nuveen Credit Income Fund, Nuveen Preferred Securities and Income Fund and Nuveen Strategic Income Fund may invest in contingent capital securities (sometimes referred to as "CoCos"). CoCos are hybrid securities, issued primarily by non-U.S. financial institutions, which have loss absorption mechanisms benefitting the issuer built into their terms. CoCos are not preferred securities. CoCos provide for mandatory conversion into the common stock of the issuer or a permanent or temporary full or partial write-down of the principal amount of the security upon the occurrence of certain triggers linked to minimum regulatory capital thresholds. In addition, they may explicitly provide for mandatory conversion or a principal write-down upon the occurrence of certain events such as regulatory bodies calling into question the issuing institution’s continued viability as a going-concern. Equity conversion or principal write-down features are tailored to the issuer and its regulatory requirements and, unlike traditional convertible securities, conversions are not voluntary and are not intended to benefit the investor.

Master Limited Partnerships

As a principal investment strategy, Nuveen Flexible Income Fund may invest in master limited partnerships (MLPs). An MLP is an entity, most commonly a limited partnership, that is taxed as a partnership, publicly traded and listed on a national securities exchange. Holders of common units of MLPs typically have limited control and limited voting rights as compared to holders of a corporation’s common shares. Preferred units issued by MLPs are not typically listed or traded on an exchange. Holders of preferred units can be entitled to a wide range of voting and other rights. Debt securities of MLPs are similar to debt securities of other companies. Such securities may be rated or unrated, may be above or below investment-grade quality, and may carry fixed or floating interest rates. MLPs are limited by the Internal Revenue Code to only apply to enterprises that engage in certain businesses, mostly pertaining to the use of natural resources, such as petroleum and natural gas extraction and transportation. Some real estate enterprises may also qualify as MLPs.

Covered Calls

Nuveen Flexible Income Fund may sell covered call options in an attempt to generate increased total return from a security in which the Fund holds a long position. A call option enables the purchaser to elect to receive a security at a predetermined price and time. A call option written by the Fund on a security is “covered” if the Fund owns the


58	Section 2 How We Manage Your Money

security underlying the call or has an absolute and immediate right to acquire that security without additional cash consideration upon conversion or exchange of other securities held by the Fund. A call option is also covered if the Fund holds a call on the same security as the call written where the exercise price of the call held is (i) equal to or less than the exercise price of the call written or (ii) greater than the exercise price of the call written, provided the difference is maintained by the Fund in segregated assets.

Short Sales

Nuveen Flexible Income Fund may take short positions in equity securities, which are often referred to as “short sales.” A short sale is a sale of a security the Fund has borrowed, with the expectation that the security will underperform the market. To settle the short sale transaction, the Fund buys the same security at a later date and returns it to the lender of the security. The Fund makes money on a short position if the market price of the security goes down after the short sale or if the market price of the securities it buys with the proceeds of the short sale increases more than that of the security sold short. Conversely, if the price of the security sold short goes up after the short sale, the Fund loses money because it has to pay more to replace the borrowed security than it received when it sold the security short. The Fund may use all or a portion of the proceeds of its short sales to purchase additional portfolio securities. This practice is considered “leverage” and may involve substantial risk.

Collateralized Loan Obligations

As a principal investment strategy, Nuveen Credit Income Fund may invest in collateralized loan obligations (“CLOs”). A CLO is an asset-backed security whose underlying collateral is a pool of loans, which may include, among others, domestic and foreign floating rate and fixed rate senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade. The Fund and other investors in CLOs ultimately bear the credit risk of the underlying collateral. CLOs issue classes or “tranches” that offer various maturity, risk and yield characteristics. Tranches are categorized as senior, mezzanine and subordinated/equity, according to their degree of risk. If there are defaults or the relevant collateral otherwise underperforms, scheduled payments to senior tranches of the CLOs take precedence over those of mezzanine tranches and scheduled payments to mezzanine tranches take precedence over those to subordinated/equity tranches. Because it is partially protected from defaults, a senior tranche of a CLO typically has higher credit ratings and lower yields than its underlying collateral and may be rated investment grade. If a CLO triggers an event of default as a result of failing to make payments when due or for other reasons, the CLO would be subject to the possibility of liquidation, which could result in full loss of value to the CLO equity or junior debt investors.

Financial Services Company Securities

Nuveen Preferred Securities and Income Fund intends to invest at least 25% of its assets in securities of companies principally engaged in financial services. Nuveen Strategic Income Fund currently invests a significant portion of its assets in the financial services sector, although this may change over time, Financial services companies include, but are not limited to, companies involved in activities such as banking, mortgage finance, consumer finance, specialized finance, investment banking and brokerage, asset management and custody, corporate lending, insurance, and financial investment, and real estate, including but not limited to real estate investment trusts.

Non-U.S. Investments

As a principal investment strategy, the Funds may invest in securities of non-U.S. issuers. The Funds will classify an issuer of a security as being a U.S. or non-U.S. issuer based on the determination of an unaffiliated, recognized financial data provider. Such


Section 2 How We Manage Your Money	59

determinations are based on a number of criteria, such as the issuer’s country of domicile, the primary exchange on which the security trades, the location from which the majority of the issuer’s revenue comes, and the issuer’s reporting currency.

Nuveen Credit Income Fund and Nuveen Strategic Income Fund may invest in issuers located in emerging markets. Emerging market countries include any country other than Canada, the United States and the countries comprising the MSCI EAFE^{^®} Index (currently, Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom).

Other Investment Companies

As a principal investment strategy, Nuveen Credit Income Fund may invest in securities of other open-end or closed-end investment companies, including ETFs. The remaining Funds may invest in securities of other investment companies as a non-principal investment strategy. An ETF is an investment company that holds a portfolio of securities generally designed to track the performance of a securities index, including industry, sector, country and region indexes. ETFs trade on a securities exchange and their shares may, at times, trade at a premium or discount to their net asset value.

As a shareholder in an investment company, the Funds will bear their ratable share of that vehicle’s expenses, and would remain subject to payment of the Funds’ advisory and administrative fees with respect to assets so invested. Shareholders would therefore be subject to duplicative expenses to the extent the Funds invest in an investment company. In addition, the Funds will incur brokerage costs when purchasing and selling shares of ETFs. Securities of investment companies may be leveraged, in which case the value and/or yield of such securities will tend to be more volatile than securities of unleveraged vehicles.

Generally, investments in other investment companies (including ETFs) are subject to statutory limitations prescribed by the Investment Company Act of 1940, as amended (the “1940 Act”). These limitations include a prohibition on a Fund acquiring more than 3% of the voting shares of any other investment company, and a prohibition on investing more than 5% of the Fund’s total assets in the securities of any one investment company or more than 10% of its total assets, in the aggregate, in investment company securities. Subject to certain conditions, the Funds may invest in money market funds beyond the statutory limits described above.

Cash Equivalents and Short-Term Investments

As a non-principal investment strategy, the Funds may invest in cash and in U.S. dollar-denominated high-quality money market instruments and other short-term securities, including money market funds, in such proportions as warranted by prevailing market conditions and the Funds’ principal investment strategies. Under normal market conditions, Nuveen High Yield Income Fund may hold up to 10% of its net assets in these holdings. The Funds may temporarily invest without limit in such holdings for liquidity purposes, or in an attempt to respond to adverse market, economic, political or other conditions. Being invested in these securities may keep a Fund from participating in a market upswing and prevent a Fund from achieving its investment objective(s).

Effective Maturity and Effective Duration

Nuveen Strategic Income Fund attempts to maintain a specified weighted average effective maturity and/or weighted average effective duration of its portfolio. Generally, the longer the effective maturity or effective duration of the Fund’s portfolio, the more sensitive the Fund’s net asset value will be to changes in interest rates, which typically corresponds to higher volatility and risk.


60	Section 2 How We Manage Your Money

A bond’s maturity is the length of time until the principal is paid back. The effective maturity of a bond may be substantially shorter than its stated or final maturity. In calculating the effective maturity of bonds in the Fund’s portfolio, the sub-adviser estimates the shortening effect of expected principal prepayments and call provisions on the bonds’ maturities. Effective maturity provides a better estimate of interest rate risk under normal market conditions than stated maturity, but may underestimate interest rate risk in an environment of rising market interest rates.

Effective duration incorporates a bond’s yield, coupon, final maturity and call features into one number that is designed to estimate how much the value of a bond will change with a given change in interest rates. As a general rule, for every 1% increase or decrease in market interest rates, a bond’s price will change approximately 1% in the opposite direction for every year of the bond’s effective duration. For example, if a bond has an effective duration of 5 years and interest rates increase by 1%, the bond’s price would be expected to decline by approximately 5%. Effective duration is subject to a number of limitations. It is most useful when interest rate changes are small, rapid, and occur equally in short-term and long-term securities. In addition, it is difficult to calculate precisely for bonds with prepayment options, such as mortgage- and asset-backed securities, because the calculation requires assumptions about prepayment rates. Also, an increase in market interest rates will generally increase a bond’s effective duration, which in turn will make the value of the bond more sensitive to changes in interest rates and result in even steeper price declines in the event of further market interest rate increases. For these reasons, effective duration should not solely be relied upon to indicate the Fund’s potential price volatility in relation to changes in market interest rates.

Credit Quality

Nuveen Strategic Income Fund may not invest in securities that are rated lower than CCC or its equivalent at the time of purchase by a rating service, such as Moody’s or Standard & Poor’s, or in unrated securities of comparable quality as determined by the Fund’s sub-adviser. There is no minimum rating requirement for securities held by the other Funds. Any reference in this prospectus to a specific credit rating encompasses all gradations of that rating. For example, if the prospectus says that a Fund may invest in securities rated as low as B, the Fund may invest in securities rated B-. The rating assigned to a particular investment does not necessarily reflect the issuer’s current financial condition and does not reflect an assessment of the investment’s volatility or liquidity. Debt securities that are rated below investment grade (BB/Ba or lower) are commonly referred to as “high yield” securities or “junk” bonds. High yield bonds typically offer higher yields than investment grade bonds with similar maturities but involve greater risks, including the possibility of default or bankruptcy, and increased market price volatility.

Disclosure of Portfolio Holdings

A description of the Funds’ policies and procedures with respect to the disclosure of the Funds’ portfolio holdings is available in the Funds’ statement of additional information. A list of each Fund’s portfolio holdings is available on the Funds’ website—www.nuveen.com/mutual-funds—by navigating to your Fund’s web page and clicking on the “Characteristics” link. By following this link, you can obtain a list of your Fund’s top ten holdings as of the end of the most recent month. A complete list of portfolio holdings information is generally made available on the Funds’ website ten business days after the end of the month. This information will remain available on the website until the Funds file with the Securities and Exchange Commission their annual, semi-annual or quarterly holdings report for the fiscal period that includes the date(s) as of which the website information is current.

What the Risks Are

Risk is inherent in all investing. Investing in a mutual fund involves risk, including the risk that you may receive little or no return on your investment or even that you may lose part or all of your investment. Therefore, before investing you should consider carefully the principal risks and certain other risks that you assume when you invest in the Funds. See the “Fund Summaries” section for a description of the principal risks of investing in a particular Fund. Additional information about these risks is listed alphabetically below. The significance of any specific risk to an investment in a Fund will vary over time depending on the composition of the Fund’s portfolio, market conditions and other factors. Because of these risks, you should consider an investment in the Funds to be a long-term investment.

Principal Risks

Active management risk: The Funds’ sub-adviser actively manages each Fund’s investments. Consequently, the Funds are subject to the risk that the investment techniques and risk analyses employed by the Funds’ sub-adviser may not produce the desired results. This could cause a Fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives. Additionally, legislative, regulatory or tax developments may affect the investment techniques available to the Funds’ sub-adviser in connection with managing a Fund and such developments, as well as any deficiencies in the operating systems or controls of the sub-adviser or a Fund service provider, may also adversely affect the ability of a Fund to achieve its investment goal.

Call risk: Many bonds may be redeemed at the option of the issuer, or “called,” before their stated maturity date. In general, an issuer will call its bonds if they can be refinanced by issuing new bonds which bear a lower interest rate. A Fund is subject to the possibility that during periods of falling interest rates, a bond issuer will call its high yielding bonds. A Fund would then be forced to invest the unanticipated proceeds at lower interest rates or in securities with a higher risk of default, which may adversely impact the Fund’s performance. Such redemptions and subsequent reinvestments would also increase a Fund's portfolio turnover. If the called bond was purchased or is currently valued at a premium, the value of the premium may be lost in the event of prepayment. Call risk is generally higher for long-term bond funds.

Collateralized loan obligations risk: Nuveen Credit Income Fund may invest in CLOs. A CLO is an asset-backed security whose underlying collateral is a pool of loans, which may include, among others, domestic and foreign floating rate and fixed rate senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. In addition to the risks associated with loans, illiquid investments and high-yield securities described below, investments in CLOs carry additional risks including, but not limited to, the risk that: (1) distributions from the collateral may not be adequate to make interest or other payments; (2) the quality of the collateral may decline in value or default; (3) the Fund may invest in tranches of CLOs that are subordinate to other tranches; (4) the complex structure of the CLO may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results; and (5) the CLO’s manager may perform poorly. CLOs may charge management and other administrative fees, which are in addition to those of the Fund.

Contingent capital security risk: As a principal investment strategy, Nuveen Credit Income Fund, Nuveen Preferred Securities and Income Fund and Nuveen Strategic


62	Section 2 How We Manage Your Money

Income Fund may invest in CoCos. A loss absorption mechanism trigger event for CoCos would likely be the result of, or related to, the deterioration of the issuer’s financial condition (e.g., a decrease in the issuer’s capital ratio) and status as a going concern. In such a case, with respect to CoCos that provide for conversion into common stock upon the occurrence of the trigger event, the market price of the issuer’s common stock received by a Fund will have likely declined, perhaps substantially, and may continue to decline, which may adversely affect the Fund’s net asset value. Further, the issuer’s common stock would be subordinate to the issuer’s other classes of securities and therefore would worsen a Fund’s standing in a bankruptcy proceeding. In addition, because the common stock of the issuer may not pay a dividend, investors in these instruments could experience a reduced income rate, potentially to zero. In view of the foregoing, CoCos are often rated below investment grade and are subject to the risks of high yield securities.

CoCos may be subject to an automatic write-down (i.e., the automatic write-down of the principal amount or value of the securities, potentially to zero, and the cancellation of the securities) under certain circumstances, which could result in a Fund losing a portion or all of its investment in such securities. In addition, the Fund may not have any rights with respect to repayment of the principal amount of the securities that has not become due or the payment of interest or dividends on such securities for any period from (and including) the interest or dividend payment date falling immediately prior to the occurrence of such automatic write-down. An automatic write-down could also result in a reduced income rate if the dividend or interest payment is based on the security’s par value. Coupon payments on CoCos may be discretionary and may be cancelled by the issuer for any reason or may be subject to approval by the issuer’s regulator and may be suspended in the event there are insufficient distributable reserves.

In certain scenarios, investors in CoCos may suffer a loss of capital ahead of equity holders or when equity holders do not. There is no guarantee that a Fund will receive a return of principal on CoCos. Any indication that an automatic write-down or conversion event may occur can be expected to have a material adverse effect on the market price of CoCos.

The prices of CoCos may be volatile. Additionally, the trading behavior of a given issuer’s CoCo may be strongly impacted by the trading behavior of other issuers’ CoCos, such that negative information from an unrelated CoCo may cause a decline in value of one or more CoCos held by a Fund. Accordingly, the trading behavior of CoCos may not follow the trading behavior of other similarly structured securities.

CoCos are issued primarily by financial institutions. Therefore, CoCos present substantially increased risks at times of financial turmoil, which could affect financial institutions more than companies in other sectors and industries.

Convertible security risk: As a principal investment strategy, Nuveen Flexible Income Fund, Nuveen Floating Rate Income Fund and Nuveen Preferred Securities and Income Fund may invest in convertible securities. Convertible securities are subject to certain risks of both equity and debt securities. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, a convertible security’s market value also tends to reflect the market price of the common stock of the issuing company. Convertible securities are also exposed to the risk that an issuer is unable to meet its obligation to make dividend or interest and principal payments when due as a result of changing financial or market conditions.


Section 2 How We Manage Your Money	63

Mandatory convertible securities are distinguished as a subset of convertible securities because the conversion is not optional and the conversion price at maturity is based solely upon the market price of the underlying common stock, which may be significantly less than par or the price (above or below par) paid. Mandatory convertible securities generally do not limit the potential for loss to the same extent as securities convertible at the option of the holder.

Covered call risk: Covered call risk is the risk that Nuveen Flexible Income Fund will forgo, during the option’s life, the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the strike price of the call, but has retained the risk of loss should the price of the underlying security decline. In addition, as the Fund writes covered calls over more of its portfolio, its ability to benefit from capital appreciation becomes more limited. The writer of an option has no control over the time when it may be required to fulfill its obligation as a writer of the option. Once an option writer has received an exercise notice, it cannot effect a closing purchase transaction in order to terminate its obligation under the option and must deliver the underlying security at the exercise price. Additionally, the hours of trading for options may not conform to the hours during which the underlying securities are traded. To the extent that the options markets close before the markets for the underlying securities, significant price and rate movements can take place in the underlying markets that cannot be reflected in the options market. If certain events affecting the underlying equity security occur, the exercise price of an option may be adjusted downward before the option’s expiration, which may reduce the Fund’s capital appreciation potential on the underlying security.

Credit risk: Credit risk is the risk that an issuer of a security held by a Fund may be, or perceived (whether by market participants, rating agencies, pricing services or otherwise) to be, unable or unwilling to make dividend, interest and principal payments and the related risk that the value of a security may decline because of concerns about the issuer’s ability or willingness to make such payments. Securities are subject to varying degrees of credit risk, which are often reflected in credit ratings. The credit rating of a security may be lowered or, in some cases, withdrawn if the issuer suffers adverse changes in its financial condition, which can lead to greater volatility in the price of the security and in shares of a Fund, can negatively impact the value of the bond and the shares of a Fund, and can also affect the security’s liquidity and make it more difficult for a Fund to sell. When a Fund purchases unrated securities, it will depend on the sub-adviser’s analysis of credit risk without the assessment of an independent rating organization, such as Moody’s or Standard & Poor’s. Issuers of unrated securities, issuers with significant debt services requirements in the near to mid-term and issuers with less capital and liquidity to absorb additional expenses may have greater credit risk. Additionally, credit risk is heightened in market environments where interest rates are rising, particularly when rates are rising significantly, to the extent that an issuer is less willing or able to make payments when due.

To the extent that a Fund holds securities that are secured or guaranteed by financial institutions or insurance companies, changes in the credit quality of such obligors could cause the values of these securities to decline. Security insurance does not guarantee the value of either individual securities or the shares of a Fund. Additionally, a Fund could be delayed or hindered in the enforcement of its rights against an issuer or guarantor.

Credit spread risk: Credit spread risk is the risk that credit spreads (i.e., the difference in yield between securities that is due to differences in their credit quality) may increase when the market believes that bonds generally have a greater risk of default. Increasing


64	Section 2 How We Manage Your Money

credit spreads may reduce the market values of a Fund’s securities. Credit spreads often increase more for lower rated and unrated securities than for investment grade securities. In addition, when credit spreads increase, reductions in market value will generally be greater for longer-maturity securities.

Currency risk: Changes in currency exchange rates will affect the value of non-U.S. securities, the value of dividends and interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities, and hence will affect the net asset value of a Fund that invests in such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of a Fund to the extent it invests in such non-U.S. securities. Even though the non-U.S. securities held by Nuveen Flexible Income Fund, Nuveen Floating Rate Income Fund and Nuveen High Yield Income Fund are traded in U.S. dollars, their prices are typically indirectly influenced by currency fluctuations.

Cybersecurity risk: Intentional cybersecurity breaches include: unauthorized access to systems, networks or devices (such as through “hacking” activity); infection from computer viruses or other malicious software code; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. In addition, unintentional incidents can occur, such as the inadvertent release of confidential information (possibly resulting in the violation of applicable privacy laws).

A cybersecurity breach could result in the loss or theft of customer data or funds, the inability to access electronic systems (“denial of services”), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or costs associated with system repairs. Such incidents could cause a Fund, a Fund’s adviser or sub-adviser, a financial intermediary, other service providers, or the issuers of securities held by a Fund to incur regulatory penalties, reputational damage, additional compliance costs or financial loss. Negative impacts on a Fund could include the inability to calculate net asset value, transact business, process transactions on behalf of shareholders or safeguard data. In addition, such incidents could affect issuers in which a Fund invests, and thereby cause the Fund’s investments to lose value.

Derivatives risk: As a principal investment strategy, Nuveen Credit Income Fund, Nuveen Flexible Income Fund, Nuveen Floating Rate Income Fund, Nuveen High Yield Income Fund and Nuveen Strategic Income Fund may utilize derivatives. The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities, including leverage risk, market risk, counterparty risk, liquidity risk, operational risk and legal risk. Operational risk generally refers to risk related to potential operational issues, including documentation issues, settlement issues, systems failures, inadequate controls and human error, and legal risk generally refers to insufficient documentation, insufficient capacity or authority of counterparty, or legality or enforceability of a contract.

Derivatives can be highly volatile, illiquid and difficult to value, and there is the risk that changes in the value of a derivative held by a Fund will not correlate with the asset, index or rate underlying the derivative contract. Changes in the value of a derivative may also create margin delivery or settlement obligations for a Fund.

The use of derivatives can lead to losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the contract. A derivative transaction also involves the risk that a loss may be sustained as a result of the failure of the counterparty to the contract to make required payments. These risks are heightened when the management team uses derivatives to


Section 2 How We Manage Your Money	65

enhance a Fund’s return or as a substitute for a position or security, rather than solely to hedge (or offset) the risk of a position or security held by the Fund.

A Fund may use derivatives to hedge risk. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund’s hedging transactions will be effective. The use of hedging may result in certain adverse tax consequences.

In addition, when a Fund engages in certain derivative transactions, it is effectively leveraging its investments, which could result in exaggerated changes in the net asset value of the Fund’s shares and can result in losses that exceed the amount originally invested. The success of a Fund’s derivatives strategies will depend on the sub-adviser’s ability to assess and predict the impact of market or economic developments on the underlying asset, index or rate and the derivative itself, without the benefit of observing the performance of the derivative under all possible market conditions.

A Fund may also enter into OTC transactions in derivatives. Transactions in the OTC markets generally are conducted on a principal-to-principal basis. The terms and conditions of these instruments generally are not standardized and tend to be more specialized or complex, and the instruments may be harder to value. In general, there is less governmental regulation and supervision of transactions in the OTC markets than of transactions entered into on organized exchanges. In addition, certain derivative instruments and markets may not be liquid, which means a Fund may not be able to close out a derivatives transaction in a cost-efficient manner.

Short positions in derivatives may involve greater risks than long positions, as the risk of loss on short positions is theoretically unlimited (unlike a long position, in which the risk of loss may be limited to the notional amount of the instrument).

Swap agreements may involve fees, commissions or other costs that may reduce a Fund’s gains from a swap agreement or may cause the Fund to lose money.

Futures contracts are subject to the risk that an exchange may impose price fluctuation limits, which may make it difficult or impossible for a Fund to close out a position when desired.

Options contracts may expire unexercised, which may cause a Fund to realize a capital loss equal to the premium paid on a purchased option or a capital gain equal to the premium received on a written option.

Nuveen Credit Income Fund and Nuveen Strategic Income Fund may invest in currency forwards. Currency forwards may be individually negotiated and privately traded, exposing them to credit and counterparty risks. The precise matching of the currency forward amounts and the value of the instruments denominated in the corresponding currencies will not generally be possible because the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the date on which the contract is entered into and the date it matures.

Dollar roll transaction risk: Nuveen Strategic Income Fund may invest in dollar roll transactions. In a dollar roll transaction, the Fund sells mortgage-backed securities for delivery in the current month while contracting with the same party to repurchase similar securities at a future date. Because the Fund gives up the right to receive principal and interest paid on the securities sold, a mortgage dollar roll transaction will diminish the investment performance of the Fund unless the difference between the price received for the securities sold and the price to be paid for the securities to be purchased in the future, plus any fee income received, exceeds any income, principal payments, and


66	Section 2 How We Manage Your Money

appreciation on the securities sold as part of the mortgage dollar roll. Whether mortgage dollar rolls will benefit the Fund may depend upon the sub-adviser’s ability to predict mortgage prepayments and interest rates. In addition, the use of mortgage dollar rolls by the Fund increases the amount of the Fund’s assets that are subject to market risk, which could increase the volatility of the price of the Fund’s shares. These transactions are also subject to the risk that the counterparty to the transaction may not or be unable to perform in accordance with the terms of the instrument.

Emerging markets risk: As a principal investment strategy, Nuveen Credit Income Fund and Nuveen Strategic Income Fund may invest in securities of issuers located in emerging market countries. The risk of foreign investment often increases in countries with emerging markets or that are otherwise economically tied to emerging market countries. Emerging markets generally do not have the level of market efficiency and strict standards in accounting, auditing, financial reporting, recordkeeping and securities regulation to be on par with advanced economies. Additionally, certain emerging markets do not provide information to or cooperate with the Public Company Accounting Oversight Board or other U.S. regulators. Certain emerging market countries may also face other significant internal or external risks, such as the risk of war, macroeconomic, geopolitical, global health conditions, and ethnic, religious and racial conflicts. Obtaining disclosures comparable to frequency, availability and quality of disclosures required by securities in the U.S. may be difficult. As a result, there could be less information about issuers in emerging market countries, which could negatively affect the ability of the Fund’s sub-adviser to evaluate local companies or their potential impact on the Fund’s performance. Investments in emerging markets come with much greater risk due to political instability, domestic infrastructure problems and currency volatility. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. In addition, foreign investors such as a Fund are subject to a variety of special restrictions in many emerging market countries. Shareholder claims that are available in the U.S. (including derivative litigation), as well as regulatory oversight, authority and enforcement actions that are common in the U.S. by regulators, may be difficult or impossible for shareholders of securities in emerging market countries or for U.S. authorities to pursue. National policies (including sanctions programs) may limit a Fund’s investment opportunities including restrictions on investment in issuers or industries deemed sensitive to national interests.

Equity security risk: As a principal investment strategy, Nuveen Flexible Income Fund and Nuveen Floating Rate Income Fund may invest in equity securities. Equity securities in a Fund’s portfolio may decline significantly in price over short or extended periods of time. Even a long-term investment approach cannot guarantee a profit. Price changes may occur in the market as a whole, or they may occur in only a particular country, company, industry, or sector of the market. Conversely, the value of Nuveen Flexible Income Fund’s short positions, if any, may decline because of an increase in the equity market as a whole or because of increases in a particular company, industry, or sector of the market. From time to time, a Fund may invest a significant portion of its assets in companies in one or more related sectors or industries which would make the Fund more vulnerable to adverse developments affecting such sectors or industries. Adverse events in any part of the U.S. and global financial markets may have unexpected negative effects on equity markets. These events may at times result in unusually high market volatility, including short-term volatility, which could negatively affect Fund performance.


Section 2 How We Manage Your Money	67

A variety of factors can negatively affect the price of a particular company's equity securities. These factors may include, but are not limited to: poor earnings, a loss of customers, a cut in dividends, certain management decisions, litigation against the company, general unfavorable performance of the company's sector or industry, or changes in government regulations affecting the company or its industry.

ETF risk: As a principal investment strategy, Nuveen Credit Income Fund may invest in ETFs. Like any fund, an ETF is subject to the risks of the underlying securities that it holds. In addition, investments in ETFs present certain risks that do not apply to investments in traditional mutual funds. For index-based ETFs, while such ETFs seek to achieve the same returns as a particular market index, the performance of an ETF may diverge from the performance of such index (commonly known as tracking error). ETFs are subject to fees and expenses (like management fees and operating expenses) and the Fund will indirectly bear its proportionate share of any such fees and expenses paid by the ETFs in which it invests. Moreover, ETF shares may trade at a premium or discount to their net asset value. As ETFs trade on an exchange, they are subject to the risks of any exchange-traded instrument, including: (i) an active trading market for its shares may not develop or be maintained, (ii) market makers or authorized participants may decide to reduce their role or step away from these activities in times of market stress, (iii) trading of its shares may be halted by the exchange, (iv) the difference between the bid and ask spread of a given ETF may negatively affect the value the Fund may receive upon sale of that ETF, and (v) its shares may be delisted from the exchange.

Financial services sector risk: Nuveen Preferred Securities and Income Fund intends to invest at least 25% of its assets in securities of companies principally engaged in financial services. This makes the Fund more susceptible to adverse economic or regulatory occurrences affecting the financial services sector. The Fund is also subject to the risks of investing in the individual industries and securities that comprise the financial services sector, such as the bank, diversified financials, real estate (including REITs) and insurance industries. Investments in the financial services sector poses risks, including the following:

· Financial services companies may suffer a setback if regulators change the rules under which they operate.

· Unstable interest rates can have a disproportionate effect on the financial services sector.

· The profitability of companies in the financial sector is largely dependent upon the availability and cost of capital which may fluctuate significantly in response to changes in interest rates and general economic developments.

· Financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, such as a high level of loans to real estate developers, which makes them vulnerable to economic conditions that affect that sector.

· Financial services companies have been affected by increased competition, which could adversely affect the profitability or viability of such companies.

· Financial services companies have been significantly and negatively affected by the downturn in the subprime mortgage lending market and the resulting impact on the world’s economies.


68	Section 2 How We Manage Your Money

· Financial services companies are subject to extensive government regulation that may limit the amounts and types of loans and other financial commitments that such companies can make.

Foreign investment risk: Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to or different than those of issuers that are located in or principally operated in the United States due to political, social and economic developments abroad, as well as armed conflicts and different regulatory environments and laws, potential seizure by the government of company assets, higher taxation, withholding taxes on dividends and interest and limitations on the use or transfer of portfolio assets. If any of these events were to occur, the affected security may experience drastic declines. In the event of a seizure of assets by a non-U.S. government, a Fund could lose its entire investment in that particular country.

To the extent a Fund invests in depositary receipts, the Fund will be subject to many of the same risks as when investing directly in non-U.S. securities. The holder of an unsponsored depositary receipt may have limited voting rights and may not receive as much information about the issuer of the underlying securities as would the holder of a sponsored depositary receipt.

Other non-U.S. investment risks include the following:

· Enforcing legal rights may be difficult, costly and slow in non-U.S. countries, and there may be special problems enforcing claims against non-U.S. governments.

· Non-U.S. companies may not be subject to accounting, auditing, financial reporting or recordkeeping standards or governmental supervision comparable to U.S. companies, and there may be less public information about their operations.

· Non-U.S. markets may be less liquid and more volatile and may be more difficult to value than U.S. markets.

· The U.S. and non-U.S. markets often rise and fall at different times or by different amounts due to economic or other developments, including armed conflict or political, social or diplomatic events, particular to a given country or region. This phenomenon would tend to lower the overall price volatility of a portfolio that included both U.S. and non-U.S. securities. Sometimes, however, global trends will cause the U.S. and non-U.S. markets to move in the same direction, reducing or eliminating the risk reduction benefit of international investing.

· Non-U.S. securities traded on foreign exchanges may be subject to further risks due to the inexperience of local investment professionals and financial institutions, the possibility of permanent or temporary termination of trading, and greater spreads between bid and asked prices for securities. In addition, non-U.S. exchanges and investment professionals are subject to less governmental regulation, and commissions may be higher than in the United States. Also, there may be delays in the settlement of non-U.S. exchange transactions. To the extent that the underlying securities held by a Fund trade on foreign exchanges or in foreign markets that may be closed when the U.S. markets are open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security.

· A Fund’s income from non-U.S. issuers may be subject to non-U.S. withholding taxes. In some countries, the Fund also may be subject to taxes on trading profits and, on certain securities transactions, transfer or stamp duties tax. To the extent non-U.S. income taxes are paid by the Fund, U.S. shareholders may be entitled to a credit or deduction for U.S. tax purposes.


Section 2 How We Manage Your Money	69

Some countries restrict to varying degrees foreign investment in their securities markets. In some circumstances, these restrictions may limit or preclude investment in certain countries or may increase the cost of investing in securities of particular companies. Non-U.S. countries may be subject to economic sanctions or other measures by the United States or other governments. The type and severity of sanctions and other similar measures, including counter sanctions and other retaliatory actions, that may be imposed could vary broadly in scope, and their impact is impossible to predict. The imposition of sanctions could, among other things, cause a decline in the value and/or liquidity of securities issued by the sanctioned country or companies located in or economically tied to the sanctioned country and increase market volatility and disruption in the sanctioned country and throughout the world. Sanctions and other similar measures could limit or prevent a Fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of securities transactions, and significantly impact the Fund’s liquidity and performance.

Frequent trading risk: A Fund's portfolio turnover rate may exceed 100%. Frequent trading of portfolio securities may produce capital gains, which are taxable to shareholders when distributed. Frequent trading may also increase the amount of commissions or mark-ups to broker-dealers that a Fund pays when it buys and sells securities, which may detract from the Fund’s performance.

High yield securities risk: Securities that are rated below-investment grade are commonly referred to as “high yield” securities or “junk” bonds. High yield securities (and similar quality unrated securities) usually offer higher yields than investment grade securities, but also involve more risk. Analysis of the creditworthiness of issuers of high yield securities may be more complex than for issuers of higher rated debt securities. High yield securities are considered to be speculative with respect to the ability to pay interest and repay principal. High yield securities may be more susceptible to real or perceived adverse economic conditions than investment grade securities, and they generally have more volatile prices, carry more risk to principal and are more likely to experience a default. In addition, high yield securities generally are less liquid than investment grade securities. Any investment in distressed or defaulted securities subjects a Fund to even greater credit risk than investments in other below-investment grade securities.

Illiquid investments risk: Certain securities held by Nuveen Credit Income Fund are illiquid investments, which may be difficult to sell for the value at which they are carried, if at all, or at any price within the desired time frame. Illiquid investments are those that are not reasonably expected to be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Pursuant to applicable SEC regulations, the Fund may not invest more than 15% of its net assets in illiquid investments. The Fund has implemented a liquidity risk management program and related procedures to identify illiquid investments pursuant to this regulation. The Fund may be limited in its ability to invest in illiquid and “less liquid” investments, which may adversely affect the Fund’s performance and ability to achieve its investment objective. The Fund’s investments in illiquid investments may reduce the returns of the Fund because it may be unable to sell the illiquid investment at an advantageous time or price, which could prevent the Fund from taking advantage of other investment opportunities. There is also a risk that unusually high redemption requests, including redemption requests from certain large shareholders (such as institutional investors) or asset allocation changes, may make it difficult for the Fund to sell investments in sufficient time to allow it to meet redemptions or require the Fund to sell illiquid investments at reduced prices or under unfavorable


70	Section 2 How We Manage Your Money

conditions. Illiquid investments may trade less frequently, in lower quantities and/or at a discount as compared to more liquid investments, which may cause the Fund to receive distressed prices and incur higher transaction costs when selling such investments. Securities that are liquid at the time of purchase may subsequently become illiquid due to events such as adverse developments for an issuer, industry-specific developments, market events, rising interest rates, changing economic conditions or investor perceptions and geopolitical risk.

Income risk: A Fund’s income could decline during periods of falling interest rates because the Fund generally may have to invest the proceeds from sales of Fund shares, as well as the proceeds from maturing portfolio securities (or portfolio securities that have been called, see “Call risk” above, or prepaid, see "Mortgage- and asset-backed securities risk" below), in lower-yielding securities. In addition, a Fund’s income could decline when the Fund experiences defaults on debt securities or defaults or deferrals on preferred securities it holds. Furthermore, a Fund's income from dividends may decline, which may decrease the distributions by the Fund. To the extent that a Fund invests in floating-rate securities, the income generated from such securities will decrease during periods of falling interest rates.

Interest rate risk: Fixed-rate securities held by a Fund will fluctuate in value with changes in interest rates. In general, fixed-rate securities will increase in value when interest rates fall and decrease in value when interest rates rise. Short-term and long-term interest rates do not necessarily move in the same amount or in the same direction. Changing interest rates may have unpredictable effects on markets, result in heightened market volatility and detract from a Fund’s performance to the extent that it is exposed to such interest rates. A Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. Higher periods of inflation could lead to government fiscal policies which raise interest rates. Longer-term fixed-rate securities are generally more sensitive to interest rate changes. Therefore, a fund that has a portfolio with a longer weighted average maturity or effective duration may be impacted to a greater degree than a fund that has a portfolio with a shorter weighted average maturity or effective duration. Conversely, fixed-rate securities with shorter durations or maturities will be less volatile but may provide lower returns than fixed-rate securities with longer durations or maturities. Rising interest rates also may lengthen the duration of securities with call features, since exercise of the call becomes less likely as interest rates rise, which in turn will make the securities more sensitive to changes in interest rates and result in even steeper price declines in the event of further interest rate increases. Risks associated with rising interest rates are heightened given that the U.S. Federal Reserve (the “Fed”) has, as of the date of this Prospectus, begun to sharply raise interest rates from historically low levels and has signaled an intention to continue doing so until current inflation levels align with the Fed’s long-term inflation target. A wide variety of factors can cause interest rates to rise (e.g., central bank monetary policies, inflation rates, general economic conditions). Further, rising interest rates may cause issuers to not make principal and interest payments when due. A Fund is also subject to the risk that the income generated by its investments may not keep pace with inflation. Because Nuveen Floating Rate Income Fund primarily invests in floating rate loans, interest rate risk may be reduced. However, floating rate loans are still subject to interest rate risk, and their values may decrease, if their interest rates do not reset as quickly as a general rise in interest rates.

Loan risk: As a principal investment strategy, Nuveen Credit Income Fund, Nuveen Floating Rate Income Fund, Nuveen High Yield Income Fund and Nuveen Strategic


Section 2 How We Manage Your Money	71

Income Fund invest in loans (including loan participations and assignments). In addition to risks generally associated with debt securities, loans in which a Fund may invest, including secured loans, unsecured and/or subordinated loans and loan participations, are subject to other risks. Loans generally are subject to legal or contractual restrictions on resale and may trade infrequently on the secondary market. It is sometimes necessary to obtain the consent of the borrower and/or agent before selling or assigning a floating rate loan. The lack of an active trading market for certain loans may impair the ability of a Fund to realize full value in the event of the need to sell a loan and may make it difficult to value such loans. Portfolio transactions in loans may settle in as short as seven days but typically can take up to two or three weeks, and in some cases much longer. As a result of these extended settlement periods, a Fund may incur losses if it is required to sell other investments or temporarily borrow to meet its cash needs, including satisfying redemption requests.

The amount of public information available with respect to loans may be less extensive than that available for registered or exchange listed securities. Furthermore, because a Fund’s sub-adviser may wish to invest in the publicly-traded securities of an obligor, the Fund may not have access to material non-public information regarding the obligor to which other investors have access. Loans may not be considered “securities” under the federal securities laws and, as a result, a Fund may not be entitled to rely on the anti-fraud or other protections afforded by such laws.

Interests in secured loans have the benefit of collateral and, typically, of restrictive covenants limiting the ability of the borrower to further encumber its assets. However, in periods of high demand by lenders for loan investments, borrowers may limit these restrictive covenants and weaken the ability of lenders like a Fund from accessing the collateral securing the loan. Additionally, loans with fewer restrictive covenants may provide the borrower with more flexibility to take actions that may be detrimental to the lender or limit the lender’s ability to declare a default, which may hinder a Fund’s ability to reprice credit risk associated with the borrower and mitigate potential loss. A Fund may experience relatively greater realized or unrealized losses or delays and expenses in enforcing its rights with respect to loans with fewer restrictive covenants. There is also a risk that the value of any collateral securing a loan in which a Fund has an interest may decline and that the collateral may not be sufficient to cover the amount owed on the loan. In the event the borrower defaults, a Fund’s access to the collateral may be limited or delayed because of difficulty liquidating the collateral or by bankruptcy or other insolvency laws. The risks associated with unsecured loans, which are not backed by a security interest in any specific collateral, are higher than those for comparable loans that are secured by specific collateral. Interests in loans made to finance highly leveraged companies or transactions such as corporate acquisitions may be especially vulnerable to adverse changes in economic or market conditions. Additionally, because junior loans have a lower place in an issuer’s capital structure and may be unsecured, junior loans involve a higher degree of overall risk than senior loans of the issuer.

With respect to loan participations, a Fund may not always have direct recourse against a borrower if the borrower fails to pay scheduled principal and/or interest; may be subject to greater delays, expenses and risks than if the Fund had purchased a direct obligation of the borrower; and may be regarded as the creditor of the agent lender (rather than the borrower), subjecting the Fund to the creditworthiness of that lender as well and the ability of the lender to enforce appropriate credit remedies against the borrower.

Certain instruments in which a Fund may invest are subject to rates that are or previously were tied to LIBOR. LIBOR was a leading floating rate benchmark used in


72	Section 2 How We Manage Your Money

loans, notes, derivatives and other instruments or investments. As a result of benchmark reforms, publication of most LIBOR settings has ceased. Some LIBOR settings continue to be published, but only on a temporary, synthetic and non-representative basis. Regulated entities have generally ceased entering into new LIBOR contracts in connection with regulatory guidance or prohibitions. Replacement rates that have been identified include the Secured Overnight Financing Rate (“SOFR”), which is intended to replace U.S. dollar LIBOR and measures the cost of overnight borrowings through repurchase agreement transactions collateralized with U.S. Treasury securities, and the Sterling Overnight Index Average Rate (“SONIA”), which is intended to replace GBP LIBOR and measures the overnight interest rate paid by banks for unsecured transactions in the sterling market, although other replacement rates could be adopted by market participants. Although the transition process away from LIBOR has become increasingly well-defined in advance of the anticipated discontinuation date, there remains uncertainty regarding the future utilization of LIBOR and the nature of any replacement rate. Any potential effects of the transition away from LIBOR on a Fund or on certain instruments in which a Fund invests can be difficult to ascertain, and they may vary depending on factors that include, but are not limited to: (i) existing fallback or termination provisions in individual contracts and (ii) whether, how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new products and instruments. A Fund may continue to invest in instruments that reference LIBOR or otherwise use LIBOR reference rates due to favorable liquidity or pricing; however, new LIBOR assets may no longer be available. In addition, interest rate provisions included in such contracts may need to be renegotiated in contemplation of the transition away from LIBOR. The transition may also result in a reduction in the value of certain instruments held by a Fund or a reduction in the effectiveness of related Fund transactions such as hedges. In addition, an instrument’s transition to a replacement rate could result in variations in the reported yields of a Fund that holds such instrument. At this time, it is not possible to predict the effect of the establishment of SOFR, SONIA or any other replacement rates.

Market risk: The market value of a Fund’s investments may go up or down, sometimes rapidly or unpredictably and for short or extended periods of time. Market values may change due to the particular circumstances of individual issuers or due to general conditions impacting issuers more broadly within a specific country, region, industry, sector or asset class. Global economies and financial markets have become highly interconnected, and thus economic, market or political conditions or events in one country or region might adversely impact issuers in a different country or region. As a result, the value of a Fund’s investments may be negatively affected whether or not the Fund invests in a country or region directly impacted by such conditions or events.

Additionally, unexpected events and their aftermaths, including broad financial dislocations (such as the “great recession” of 2008-09), war, armed conflict, terrorism, the imposition of economic sanctions, bank failures (such as the March 2023 failures of Silicon Valley Bank and Signature Bank, the second- and third-largest bank failures in U.S. history), natural and environmental disasters and the spread of infectious illnesses or other public health emergencies (such as the COVID-19 coronavirus pandemic first detected in December of 2019), may adversely affect the global economy and the markets and issuers in which a Fund invests. These events could reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, or widespread unemployment, and generally have a severe negative impact on the global economy. Such events could also impair the information technology and other operational systems upon which a Fund’s service providers, including the investment adviser and sub-adviser, rely, and could otherwise disrupt the ability of employees of a


Section 2 How We Manage Your Money	73

Fund’s service providers to perform essential tasks on behalf of a Fund. Furthermore, such events could cause financial markets to experience elevated or even extreme volatility and losses, and could result in the disruption of trading and the reduction of liquidity in many instruments. In addition, sanctions and other measures could limit or prevent a Fund from buying and selling securities (in sanctioned country and other markets), significantly delay or prevent the settlement of securities transactions, and significantly impact liquidity and performance. Governmental and quasi-governmental authorities and regulators throughout the world have in the past responded to major economic disruptions with a variety of significant fiscal and monetary policy changes, including but not limited to, direct capital infusions into companies, new monetary programs and dramatically lower interest rates. An unexpected or quick reversal of these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which could adversely affect the value of a Fund’s investments. In addition, there is a possibility that the rising prices of goods and services may have an effect on the Fund. As inflation increases, the value of the Fund’s assets can decline.

Market liquidity risk: Primary dealer inventories of bonds and preferred securities are a core indication of dealers’ capacity to “make a market” in those securities. A reduction in market making capacity has the potential to decrease liquidity and increase price volatility in the markets in which a Fund invests, particularly during periods of economic or market stress. As a result of this decreased liquidity, a Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on performance. If a Fund needed to sell large blocks of securities to meet shareholder redemption requests or to raise cash, those sales could further reduce the securities’ prices and hurt performance.

MLP risk: As a principal investment strategy, Nuveen Flexible Income Fund may invest in MLPs. An investment in units of an MLP involves certain risks which differ from an investment in the securities of a corporation. Investors in an MLP normally would not be liable for the debts of the MLP beyond the amount that the investor has contributed but investors may not be shielded to the same extent that a shareholder of a corporation would be. Holders of MLP common units have the rights typically afforded to limited partners in limited partnerships. Accordingly, holders of common units will have limited control and limited voting rights on matters affecting the partnership. Holders of common units may also be subject to potential conflicts of interest with the MLP’s general partner, including those arising from incentive distribution payments.

Investments held by MLPs may be relatively illiquid, limiting the MLPs’ ability to vary their portfolios promptly in response to changes in economic or other conditions, and MLPs may have limited financial resources. Common units of MLPs may trade infrequently and in limited volume, and they may be subject to more abrupt or erratic price movements than common shares of larger or more broadly-based companies. The Fund’s investment in MLPs also subjects it to the risks associated with the specific industry or industries in which the MLPs invest. MLPs are generally considered interest-rate sensitive investments, and during periods of interest rate volatility, may not provide attractive returns.

In addition, there are certain tax risks associated with investments in MLPs. The benefit derived from an investment in an MLP is largely dependent on the MLP being treated as a partnership for federal income tax purposes. A change to current tax law, or a change in the underlying business mix of a given MLP, could result in an MLP being treated as a corporation for federal income tax purposes. If an MLP were treated as a corporation, the MLP would be required to pay federal income tax on its taxable income. This would reduce the amount of cash available for distribution by the MLP, which could result in a


74	Section 2 How We Manage Your Money

reduction of the value of the Fund’s investment in the MLP and lower income to the Fund. Additionally, since MLPs generally conduct business in multiple states, the Fund may be subject to income or franchise tax in each of the states in which the partnership does business. The additional cost of preparing and filing the tax returns and paying the related taxes may adversely impact the Fund’s return on its investment in MLPs.

Money market fund risk: As a principal investment strategy, Nuveen Floating Rate Income Fund may invest in money market funds. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the FDIC or any other government agency. An investment in a money market fund, even an investment in a fund seeking to maintain a stable net asset value per share, is not guaranteed and it is possible for a Fund to lose money by investing in money market funds. If the liquidity of a money market fund’s portfolio deteriorates below certain levels, the money market fund may suspend redemptions (i.e., impose a redemption gate) and thereby prevent a Fund from selling its investment in the money market fund or impose a fee of up to 2% on amounts the Fund redeems from the money market fund (i.e., impose a liquidity fee). These measures may result in an investment loss or prohibit a Fund from redeeming shares. In addition to the fees and expenses that a Fund directly bears, the Fund indirectly bears the fees and expenses of any money market funds in which it invests. By investing in a money market fund, a Fund will be exposed to the investment risks of the money market fund in direct proportion to such investment. Money market funds and the securities they invest in are subject to comprehensive regulations. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operation, performance and/or yield of money market funds.

Mortgage- and asset-backed securities risk: As a principal investment strategy, Nuveen Credit Income Fund, Nuveen Flexible Income Fund and Nuveen Strategic Income Fund may invest in mortgage- and/or asset-backed securities. The value of mortgage- and asset-backed securities can fall if the owners of the underlying mortgages or other obligations pay off their mortgages or other obligations sooner than expected, which could happen when interest rates fall or for other reasons.

Mortgage- and asset-backed securities are also subject to extension risk, which is the risk that rising interest rates could cause mortgages or other obligations underlying the securities to be prepaid more slowly than expected, which would, in effect, convert a short- or medium-duration mortgage- or asset-backed security into a longer-duration security, increasing its sensitivity to interest rate changes and causing its price to decline.

A mortgage-backed security may be negatively affected by the quality of the mortgages underlying such security and the structure of its issuer. For example, if a mortgage underlying a certain mortgage-backed security defaults, the value of that security may decrease.

A Fund may invest in mortgage-backed securities that are not explicitly backed by the full faith and credit of the U.S. government, and there can be no assurance that the U.S. government would provide financial support in situations in which it was not obligated to do so. Mortgage-backed securities issued by a private issuer, such as commercial mortgage-backed securities, generally entail greater risk than obligations directly or indirectly guaranteed by the U.S. government or a government-sponsored entity. There may be a limited market for such securities, especially when there is a perceived weakness in the mortgage and real estate market sectors. Without an active trading market, non-agency mortgage-backed securities held by a Fund may be particularly


Section 2 How We Manage Your Money	75

difficult to value because of the complexities involved in assessing the value of the underlying loans.

Municipal securities risk: As a principal investment strategy, Nuveen Flexible Income Fund, Nuveen Preferred Securities and Income Fund and Nuveen Strategic Income Fund may invest in municipal securities. The values of municipal securities may be adversely affected by local political and economic conditions and developments and, therefore, a Fund’s performance may be tied to the conditions in any of the states and U.S. territories where it is invested. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers. Other factors that could affect municipal securities include a change in the local, state, or national economy, a downgrade of a state's credit rating or the rating of authorities or political subdivisions of the state or another obligated party, demographic factors, ecological or environmental concerns, inability or perceived inability of a government authority to collect sufficient tax or other revenues, statutory limitations on the issuer’s ability to increase taxes, and other developments generally affecting the revenue of issuers (for example, legislation or court decisions reducing state aid to local governments or mandating additional services). This risk would be heightened to the extent that a Fund invests a substantial portion of its portfolio in the bonds of similar projects (such as those relating to the education, health care, housing, transportation, or utilities industries), in industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, municipal lease obligations, private activity bonds or moral obligation bonds) that are particularly exposed to specific types of adverse economic, business or political events. The value of municipal securities may also be adversely affected by rising health care costs, increasing unfunded pension liabilities, and by the phasing out of federal programs providing financial support. In recent periods, a number of municipal issuers have defaulted on obligations, been downgraded or commenced insolvency proceedings. Financial difficulties of municipal issuers may continue or get worse, particularly as the full economic impact of the COVID-19 coronavirus pandemic and the reductions in revenues of states and municipalities due to the pandemic are realized. In addition, the amount of public information available about municipal bonds is generally less than for certain corporate equities or bonds, meaning that the investment performance of a Fund may be more dependent on the analytical abilities of the Fund’s sub-adviser than funds that invest in stock or other corporate investments.

To the extent that a Fund invests a significant portion of its assets in the securities of issuers located in a given state or U.S. territory, it will be disproportionally affected by political and economic conditions and developments in that state or territory and may involve greater risk than funds that invest in a larger universe of securities. In addition, economic, political or regulatory changes in that state or territory could adversely affect municipal securities issuers in that state or territory and therefore the value of a Fund’s investment portfolio.

Other investment companies risk: When a Fund invests in other investment companies, such as ETFs, shareholders bear both their proportionate share of Fund expenses and, indirectly, the expenses of the other investment companies. Furthermore, a Fund is exposed to the risks to which the other investment companies may be subject.

Preferred security risk: As a principal investment strategy, Nuveen Credit Income Fund, Nuveen Flexible Income Fund, Nuveen Preferred Securities and Income Fund and Nuveen Strategic Income Fund invest in preferred securities. There are special risks associated with investing in preferred securities:


76	Section 2 How We Manage Your Money

Limited voting rights. Generally, preferred security holders have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may elect a number of directors to the issuer’s board. Generally, once all the arrearages have been paid, the preferred security holders no longer have voting rights.

In the case of certain preferred securities issued by trusts or special purpose entities, holders generally have no voting rights except if a declaration of default occurs and is continuing. In such an event, preferred security holders generally would have the right to appoint and authorize a trustee to enforce the trust’s or special purpose entity’s rights as a creditor under the agreement with its operating company.

Special redemption rights. In certain circumstances, an issuer of preferred securities may redeem the securities prior to their stated maturity date. For instance, for certain types of preferred securities, a redemption may be triggered by a change in federal income tax or securities laws or by regulatory or major corporate action. As with call provisions, a redemption by the issuer may negatively impact the return of the security held by a Fund.

Payment deferral. Generally, preferred securities may be subject to provisions that allow an issuer, under certain conditions, to skip (“non-cumulative” preferred securities) or defer (“cumulative” preferred securities) distributions without any adverse consequences to the issuer. Non-cumulative preferred securities can skip distributions indefinitely. Cumulative preferred securities typically contain provisions that allow an issuer, at its discretion, to defer distributions payments for up to 10 years. If a Fund owns a preferred security that is deferring its distribution, the Fund may be required to report income for tax purposes although it has not yet received such income. In addition, recent changes in bank regulations may increase the likelihood of issuers deferring or skipping distributions.

Subordination. Preferred securities generally are subordinated to bonds and other debt instruments in a company’s capital structure and therefore are subject to greater credit risk than those debt instruments.

Floating Rate Payments. The dividend or interest rates on preferred securities may be floating, or convert from fixed to floating at a specified future time. The market value of floating rate securities may fall in a declining interest rate environment and may also fall in a rising interest rate environment if there is a lag between the rise in interest rates and the reset. This risk may also be present with respect to fixed rate securities that will convert to a floating rate at a future time. A secondary risk associated with declining interest rates is the risk that income earned by a Fund on floating rate securities may decline due to lower coupon payments on the floating-rate securities. Finally, many financial instruments use or may use a floating rate based upon LIBOR, which was phased out. Any potential effects of the transition away from LIBOR on a Fund or on certain instruments in which a Fund invests can be difficult to ascertain. In addition, an instrument’s transition to a replacement rate could result in variations in the reported yields of a Fund that holds such instrument. At this time, it is not possible to predict the effect of the establishment of replacement rates or any other reforms to LIBOR. Any such effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to a Fund.

Fixed Rate Payments. The market value of preferred securities with fixed dividends or interest rates may decline in a rising interest rate environment.


Section 2 How We Manage Your Money	77

Liquidity. Preferred securities may be substantially less liquid than many other securities, such as U.S. government securities or common stock. Less liquid securities involve the risk that the securities will not be able to be sold at the time desired by a Fund or at prices approximating the values at which the Fund is carrying the securities on its books.

Financial services industry. The preferred securities market is comprised predominately of securities issued by companies in the financial services industry. Therefore, preferred securities present substantially increased risks at times of financial turmoil, which could affect financial services companies more than companies in other sectors and industries.

Tax risk. A Fund may invest in preferred securities or other securities the federal income tax treatment of which may not be clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult for a Fund to comply with the tax requirements applicable to regulated investment companies if the tax characterization of the Fund’s investments or the tax treatment of the income from such investments were successfully challenged by the Internal Revenue Service.

Regulatory risk. Issuers of preferred securities may be in industries that are heavily regulated and that may receive government funding. The value of preferred securities issued by these companies may be affected by changes in government policy, such as increased regulation, ownership restrictions, deregulation or reduced government funding.

Restricted securities risk: The market for restricted securities, including Rule 144A securities, typically is less active than the market for publicly traded securities. Rule 144A securities and other securities exempt from registration under the Securities Act carry the risk that their liquidity may become impaired and a Fund may be unable to dispose of the securities promptly or at current market value. In the U.S., restricted securities are typically sold only to qualified institutional buyers. An insufficient number of buyers interested in purchasing restricted securities at a particular time could adversely affect the marketability of such investments and a Fund might be unable to dispose of them promptly or at a reasonable price. In many cases, privately placed securities may not be freely transferable under the laws of the applicable jurisdiction or due to contractual restrictions on resale. As a result of the absence of a public trading market, privately placed securities may be deemed to be illiquid investments or less liquid investments and may be more difficult to value than publicly traded securities. To the extent that privately placed securities may be resold in privately negotiated transactions, the prices realized from the sales, due to lack of liquidity, could be less than those originally paid by a Fund or less than their fair market value. In addition, issuers whose securities are not registered and publicly traded may not be subject to the disclosure and other investor protection requirements that may be applicable if their securities were publicly traded. In making investments in such securities, a Fund may obtain access to material nonpublic information, which may restrict the Fund’s ability to conduct portfolio transactions in such securities.

Short sales risk: Nuveen Flexible Income Fund may take short positions in equity securities, which are often referred to as "short sales." Short sales involve the sale of a security the Fund has borrowed, with the expectation that the security will underperform the market. Short sales expose the Fund to the risk that it will be required to buy the security sold short (also known as “covering” the short position) at a time when the security has appreciated in value, thus resulting in a loss to the Fund. For instance, the lender of the borrowed security may recall the security, in which case the Fund would


78	Section 2 How We Manage Your Money

have to either borrow the security from another lender or buy the security and deliver it to the lender. The Fund may not always be able to locate another lender, and thus the Fund may be required to cover the short position at a disadvantageous price. In certain cases, purchasing a security to cover a short position can itself cause the price of the security to rise further, thereby exacerbating the loss. Although the gain is limited by the price at which the security was sold short, the potential loss on a short sale is theoretically unlimited because there is no upper limit on the price a borrowed security can attain. By contrast, a loss on a long position arises from decreases in the value of the security and is limited by the fact that a security’s value cannot go below zero. In a rising stock market, the Fund’s short positions may significantly impact the Fund’s overall performance and cause the Fund to underperform traditional long-only equity funds or to sustain losses, particularly in a sharply rising market. Short positions are more volatile than long positions due to risks inherent to short selling, including incorrect determinations of equity security valuations and/or the directional movement of stock market averages. The Fund may also pay transaction costs and borrowing fees in connection with short sales and, until the borrowed security is replaced, the Fund is required to pay to the lender amounts equal to any dividends paid during the period of the loan. When the Fund is selling a security short, it must maintain a segregated account of cash or high-grade securities equal to the margin requirement. As a result, the Fund may maintain high levels of cash or other liquid assets, which may limit the Fund’s ability to pursue other opportunities. In addition, short positions typically involve increased liquidity risk and the risk that the third party to the short sale may fail to honor its contract terms. To the extent the Fund invests the proceeds received from selling securities short in additional long positions, the Fund is engaging in a form of leverage. The use of leverage may increase the Fund’s exposure to long positions and make any change in the Fund’s net asset value greater than it would be without the use of leverage. This could result in increased volatility of returns.

In the past, in response to market events, regulatory authorities in various countries, including the United States, enacted temporary rules prohibiting the short-selling of certain stocks. If regulatory authorities were to reinstitute such rules or otherwise restrict short-selling, the Fund might not be able to fully implement its short-selling strategy.

Sovereign debt risk: As a principal investment strategy, Nuveen Credit Income Fund and Nuveen Strategic Income Fund may invest in sovereign debt instruments. Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt. This may be due to, for example, cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. Additionally, the defaulting governmental entity may restructure their debt payments, possibly without the approval of some or all debt holders. In addition, the issuer of sovereign debt may be unable or unwilling to repay due to the imposition of international sanctions and other similar measures. As a result, there is an increased budgetary and financial pressure on municipalities and heightened risk of default or other adverse credit or similar events for issuers of municipal securities, which would adversely impact a Fund’s investments. There may be limited recourse against a defaulting governmental entity as there is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected.


Section 2 How We Manage Your Money	79

Unrated security risk: Unrated securities determined by the Funds’ sub-adviser to be of comparable quality to rated securities which a Fund may purchase may pay a higher interest rate than such rated securities and be subject to a greater risk of illiquidity or price changes. Less public information is typically available about unrated securities or issuers than rated securities or issuers.

U.S. government securities risk: U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates. Securities issued or guaranteed by U.S. government agencies and instrumentalities are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. government or may be subject to certain limitations. No assurance can be given that the U.S. government will provide financial support to its agencies and instrumentalities if it is not obligated by law to do so. Therefore, securities issued by U.S. government agencies or instrumentalities that are not backed by the full faith and credit of the U.S. government may involve increased risk of loss of principal and interest. In addition, the value of U.S. government securities may be affected by changes in the credit rating of the U.S. government.

Valuation risk: The sales price a Fund could receive for any particular security may differ from the Fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology. The debt securities in which a Fund may invest typically are valued by a pricing service utilizing a range of market-based inputs and assumptions, including price quotations obtained from broker-dealers making markets in such instruments, cash flows and transactions for comparable instruments. There is no assurance that a Fund will be able to buy or sell a portfolio security at the price established by the pricing service, which could result in a gain or loss to the Fund. Pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, often at lower prices than institutional round lot trades. Over certain time periods, such differences could materially impact the performance of a Fund, which may not be sustainable. Alternative pricing services may incorporate different assumptions and inputs into their valuation methodologies, potentially resulting in different values for the same securities. As a result, if a Fund were to change pricing services, or if a Fund’s pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Fund’s net asset value.

Non-Principal Risks

Large transactions risk: A Fund may experience adverse effects due to large purchases or redemptions of Fund shares. A large redemption by an individual shareholder, or an increase in redemptions generally by Fund shareholders, may cause a Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value and liquidity. If a Fund has difficulty selling portfolio securities in a timely manner to meet redemption requests, the Fund may have to borrow money to do so. In such an instance, a Fund’s remaining shareholders would bear the costs of such borrowings, and such costs could reduce the Fund’s returns. In addition, until a Fund is able to sell securities to meet redemption requests, the Fund’s market exposure may be greater than it ordinarily would be, which would magnify the impact of any market movements on the Fund’s performance. Similarly, large Fund share purchases may adversely affect a Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would, reducing the Fund’s market exposure. Increased redemption activity may also result in unexpected taxable distributions to shareholders if such sales of


80	Section 2 How We Manage Your Money

investments resulted in gains and thereby accelerated the realization of taxable income. In addition, large redemptions could result in a Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

An affiliate of Nuveen Fund Advisors offers other open-end investment companies structured as “funds of funds” that may invest their assets in shares of the Funds and other investment companies and pooled investment vehicles (“Funds-of-Funds”). At certain times, the Funds-of-Funds may be significant shareholders of a Fund and investment decisions made with respect to the Funds-of-Funds could, under certain circumstances, negatively impact a Fund, with respect to its expenses, investment performance and liquidity profile. For instance, large purchases or redemptions of shares of a Fund by the Funds-of-Funds, whether as part of a reallocation or rebalancing strategy or otherwise, may result in the Fund having to sell securities or invest cash when it otherwise would not do so. Such transactions could increase the Fund’s transaction costs, accelerate the realization of taxable income, and, in extreme cases, could threaten the continued viability of the Fund to operate as intended.


Section 2 How We Manage Your Money	81

Section 3 How You Can Buy and Sell Shares

The Funds offer multiple classes of shares, each with a different combination of sales charges, fees, eligibility requirements and other features. Your financial advisor can help you determine which class is best for you. For further details, please see the statement of additional information. Because the prospectus and the statement of additional information are available free of charge on Nuveen’s website at www.nuveen.com, we do not disclose the following share class information separately on the website.

What Share Classes We Offer

The different share classes offered by the Funds are described below. You will pay up-front or contingent deferred sales charges on some of these share classes. In addition, some share classes are subject to annual distribution and/or service fees in the amounts described below, which are paid out of a Fund’s assets. These fees are paid to Nuveen Securities, LLC (the “Distributor”), a subsidiary of Nuveen, LLC and the distributor of the Funds, and are used primarily for providing compensation to financial intermediaries in connection with the distribution of Fund shares and for providing ongoing account services to shareholders. The Funds have adopted a distribution and service plan under Rule 12b-1 under the 1940 Act that allows each Fund to pay these distribution and service fees. More information on this plan can be found under “Distribution and Service Payments—Distribution and Service Plan.” Because fees paid under the plan are paid out of a Fund’s assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

Class A Shares

You can purchase Class A shares at the offering price, which is the net asset value per share plus an up-front sales charge. You may qualify for a reduced sales charge, or the sales charge may be waived, as described in “How to Reduce Your Sales Charge.” Class A shares are also subject to an annual service fee of 0.25% of your Fund’s average daily net assets, which compensates your financial advisor or other financial intermediary for providing ongoing service to you. The Distributor retains the service fee on accounts with no financial intermediary of record. The up-front Class A sales charges for the Funds are as follows:

Nuveen Credit Income Fund
Nuveen Flexible Income Fund
Nuveen High Yield Income Fund
Nuveen Preferred Securities and Income Fund


Amount of Purchase	Sales Charge as % of Public Offering Price		Sales Charge as % of Net Amount Invested		Maximum Financial Intermediary Commission as % of Public Offering Price

82	Section 3 How You Can Buy and Sell Shares

* You can purchase $1 million or more of Class A shares at net asset value without an up-front sales charge. The Distributor pays financial intermediaries of record at a rate of 1.00% of the first $2.5 million, plus 0.75% of the next $2.5 million, plus 0.50% of the amount over $5 million, which includes an advance of the first year’s service fee. Unless you are eligible for a waiver, you may be assessed a contingent deferred sales charge (“CDSC”) of 1.00% if you redeem any of your shares within 18 months of purchase. See “Contingent Deferred Sales Charges” below for information concerning the CDSC and “How to Reduce Your Sales Charge—CDSC Waivers and Reductions” below for information concerning CDSC waivers and reductions.

* You can purchase $1 million or more of Class A shares at net asset value without an up-front sales charge. The Distributor pays financial intermediaries of record at a rate of 1.00% of the first $2.5 million, plus 0.75% of the next $2.5 million, plus 0.50% of the amount over $5 million, which includes an advance of the first year’s service fee. Unless you are eligible for a waiver, you may be assessed a CDSC of 1.00% if you redeem any of your shares within 18 months of purchase. See “Contingent Deferred Sales Charges” below for information concerning the CDSC and “How to Reduce Your Sales Charge—CDSC Waivers and Reductions” below for information concerning CDSC waivers and reductions.

Investors may purchase Class A shares only for Fund accounts held with a financial advisor or other financial intermediary, and not directly with a Fund. In addition, Class A shares may not be available through certain financial intermediaries. Please consult with your financial intermediary to determine whether their policies allow for an investment in Class A shares.

Class C Shares

You can purchase Class C shares at the offering price, which is the net asset value per share without any up-front sales charge. Class C shares are subject to annual distribution and service fees of 1.00% of your Fund’s average daily net assets. The annual 0.25% service fee compensates your financial advisor or other financial intermediary for providing ongoing service to you. The annual 0.75% distribution fee compensates the Distributor for paying your financial advisor or other financial intermediary an ongoing sales commission as well as an advance of the first year's service and distribution fees. The Distributor retains the service and distribution fees on accounts with no financial intermediary of record. If you redeem your shares within 12 months of purchase, you will normally pay a 1.00% CDSC, which is calculated on the lower of your purchase price or redemption proceeds. You do not pay a CDSC on any


Section 3 How You Can Buy and Sell Shares	83

Class C shares you purchase by reinvesting dividends. You may qualify for a reduced CDSC, or the CDSC may be waived, as described in “How to Reduce Your Sales Charge” below.

Investors purchasing Class C shares should consider whether they would qualify for a reduced or eliminated sales charge on Class A shares that would make purchasing Class A shares a better choice. Class A share sales charges can be reduced or eliminated based on the size of the purchase, or pursuant to a letter of intent or rights of accumulation. See “How to Reduce Your Sales Charge” below.

Class C share purchase orders equaling or exceeding $1,000,000 ($500,000 for Nuveen Floating Rate Income Fund) will not be accepted. In addition, the Funds limit the cumulative amount of Class C shares that may be purchased by a single purchaser. Your financial intermediary may set lower maximum purchase limits for Class C shares. See the statement of additional information for more information.

Class C shares automatically convert to Class A shares after 8 years, thus reducing future annual expenses. Conversions occur during the month in which the 8-year anniversary of the purchase occurs. The automatic conversion is based on the relative net asset values of the two share classes without the imposition of a sales charge or fee. The automatic conversion of Class C shares to Class A shares may not apply to shares held through group retirement plan recordkeeping platforms of certain financial intermediaries who hold such shares in an omnibus account and do not track participant level share lot aging to facilitate such a conversion. Furthermore, the availability of the automatic Class C share conversion and the terms under which the conversion takes place may depend on the policies and/or system limitations of the financial intermediary through which you hold your shares. Information on intermediaries’ variations from the Class C share conversion discussed above is disclosed in the appendix to this prospectus, “Variations in Sales Charge Reductions and Waivers Through Certain Intermediaries.” Also, see “How to Reduce Your Sales Charge” below.

Investors may purchase Class C shares only for Fund accounts held with a financial advisor or other financial intermediary, and not directly with a Fund. In addition, Class C shares may not be available through certain financial intermediaries. Please consult with your financial intermediary to determine whether their policies allow for an investment in Class C shares.

Class R6 Shares

Eligible investors can purchase Class R6 shares at the offering price, which is the net asset value per share without any up-front sales charge. As Class R6 shares are not subject to sales charges or ongoing service or distribution fees, they have lower ongoing expenses than the other classes.

Class R6 shares are available to certain qualified retirement plans and other investors. There is no minimum initial investment for qualified retirement plans, health savings accounts and 529 savings plans; however, the shares must be held through plan-level or omnibus accounts held on the books of a Fund. Class R6 shares are also available for purchase by clients of financial intermediaries who charge such clients an ongoing fee for advisory, investment, consulting or related services. Such clients may include individuals, corporations, endowments and foundations. The minimum initial investment for such clients is $100,000, but this minimum will be waived for clients of financial intermediaries that have accounts holding Class R6 shares with an aggregate value of at least $100,000. The Distributor may also waive the minimum for clients of financial intermediaries anticipated to reach this Class R6 share holdings level. All other eligible investors must meet a minimum initial investment of at least $1,000,000 in a Fund. Such


84	Section 3 How You Can Buy and Sell Shares

minimum investment requirement may be applied collectively to affiliated accounts, in the discretion of the Distributor. Class R6 shares may be purchased through financial intermediaries only if such intermediaries have entered into an agreement with the Distributor to offer Class R6 shares. Class R6 shares are only available in cases where neither the investor nor the intermediary will receive any commission payments, account servicing fees, record keeping fees, 12b-1 fees, sub-transfer agent fees, so called “finder’s fees,” administration fees or similar fees with respect to Class R6 shares. Provided they meet the minimum investment and other eligibility requirements, eligible investors include:

· Qualified retirement plans held in plan-level or omnibus accounts;

· Foundations and endowment funds;

· Any state, county, or city, or its instrumentality, department, authority or agency;

· 457 plans, including 457(b) governmental entity plans and tax exempt plans;

· Omnibus or other pooled accounts registered to insurance companies, trust companies, bank trust departments, registered investment advisor firms and family offices;

· Investment companies;

· Corporations, including corporate non-qualified deferred compensation plans of such corporations;

· Collective investment trusts;

· 529 savings plans held in plan-level or omnibus accounts;

· Health savings accounts held in plan-level or omnibus accounts; and

· Discretionary accounts managed by Nuveen Fund Advisors or its affiliates.

Class R6 shares are also available for purchase, with no minimum initial investment, by the following categories of investors:

· Current and former trustees/directors of any Nuveen Fund, and their immediate family members (as defined in the statement of additional information).

· Officers of Nuveen, LLC and its affiliates, and their immediate family members.

· Full-time and retired employees of Nuveen, LLC and its affiliates, and their immediate family members.

Class R6 shares are not available directly to traditional or Roth IRAs, Coverdell Savings Accounts, Keoghs, SEPs, SARSEPs, or SIMPLE IRAs.

Nuveen Credit Income Fund does not issue Class R6 shares.

Class I Shares

You can purchase Class I shares at the offering price, which is the net asset value per share without any up-front sales charge. As Class I shares are not subject to sales charges or ongoing service or distribution fees, they have lower ongoing expenses than the other classes.

Class I shares are available for purchase by clients of financial intermediaries who charge such clients an ongoing fee for advisory, investment, consulting or related services. Such clients may include individuals, corporations, endowments and foundations. The minimum initial investment for such clients is $100,000, but this minimum will be lowered to $250 for clients of financial intermediaries that have


Section 3 How You Can Buy and Sell Shares	85

accounts holding Class I shares with an aggregate value of at least $100,000. The Distributor may also lower the minimum to $250 for clients of financial intermediaries anticipated to reach this Class I share holdings level.

Class I shares are also available for purchase by family offices and their clients. A family office is a company that provides certain financial and other services to a high net worth family or families. The minimum initial investment for family offices and their clients is $100,000, but this minimum will be lowered to $250 for clients of family offices that have accounts holding Class I shares with an aggregate value of at least $100,000. The Distributor may also lower the minimum to $250 for clients of family offices anticipated to reach this Class I share holdings level.

Class I shares are also available for purchase, with no minimum initial investment, by the following categories of investors:

· Certain employer-sponsored retirement plans.

· Certain bank or broker-affiliated trust departments.

· Advisory accounts of Nuveen Fund Advisors and its affiliates.

· Investors purchasing through a brokerage platform of a financial intermediary that has an agreement with the Distributor to offer such shares solely when acting as an agent for such investors. Investors transacting through a financial intermediary’s brokerage platform may be required to pay a commission directly to the intermediary.

· Current and former trustees/directors of any Nuveen Fund, and their immediate family members (as defined in the statement of additional information).

· Officers of Nuveen, LLC and its affiliates, and their immediate family members.

· Full-time and retired employees of Nuveen, LLC and its affiliates, and their immediate family members.

· Certain financial intermediary personnel, and their immediate family members.

· Certain other institutional investors described in the statement of additional information.

A financial intermediary through which you hold Class I shares may have the authority under its account agreement to exchange your Class I shares for another class of Fund shares having higher expenses than Class I shares if you withdraw from or are no longer eligible for the intermediary's fee-based program or under other circumstances. You may be subject to the sales charges and service and/or distribution fees applicable to the share class that you receive in such an exchange. You should contact your financial intermediary for more information about your eligibility to purchase Class I shares and the class of shares you would receive in an exchange if you no longer meet Class I eligibility requirements.

Please refer to the statement of additional information for more information about Class A, Class C, Class R6 and Class I shares, including more detailed program descriptions and eligibility requirements. Additional information is also available from your financial advisor, who can also help you prepare any necessary application forms.

Contingent Deferred Sales Charges

If you redeem Class A or Class C shares that are subject to a CDSC, you may be assessed a CDSC upon redemption. When you redeem Class A or Class C shares subject to a CDSC, your Fund will first redeem any shares that are not subject to a CDSC, and then redeem the shares you have owned for the longest period of time, unless you ask the Fund to redeem your shares in a different order. No CDSC is


86	Section 3 How You Can Buy and Sell Shares

imposed on shares you buy through the reinvestment of dividends and capital gains. The CDSC holding period is calculated on a monthly basis and begins on the first day of the month in which the purchase was made. When you redeem shares subject to a CDSC, the CDSC is calculated on the lower of your purchase price or redemption proceeds, deducted from your redemption proceeds, and paid to the Distributor. The CDSC may be waived under certain special circumstances as described below under “How You Can Buy and Sell Shares—How to Reduce Your Sales Charge—CDSC Waivers and Reductions,” in the appendix to this prospectus titled “Variations in Sales Charge Reductions and Waivers Available Through Certain Intermediaries,” and in the statement of additional information.

How to Reduce Your Sales Charge

The Funds offer a number of ways to reduce or eliminate the up-front sales charge on Class A shares. In addition, under certain circumstances, the Funds will waive or reduce the CDSC imposed on redemptions of Class C shares and certain Class A shares purchased at net asset value. The availability of the sales charge reductions and waivers discussed below will depend on the policies of the financial intermediary through which you purchase your shares. Information on intermediaries’ variations from the reductions and waivers discussed below are disclosed in the appendix to this prospectus, “Variations in Sales Charge Reductions and Waivers Available Through Certain Intermediaries.” In all instances, it is your responsibility to notify your financial intermediary at the time of purchase of any relationship or other facts qualifying you for sales charge waivers or discounts. In order to obtain waivers and discounts that are not available through your intermediary, you will have to purchase Fund shares through another intermediary.

Class A Sales Charge Reductions

· Rights of Accumulation. In calculating the appropriate sales charge on a purchase of Class A shares of a Fund, you may be able to add the amount of your purchase to the value, based on the current net asset value per share, of all of your prior purchases of any Nuveen Mutual Fund.

· Letter of Intent. Subject to certain requirements, you may purchase Class A shares of a Fund at the sales charge rate applicable to the total amount of the purchases you intend to make over a 13-month period.

For purposes of calculating the appropriate sales charge as described under Rights of Accumulation and Letter of Intent above, you may include purchases by (i) you, (ii) your spouse or domestic partner and children under the age of 21 years, and (iii) a corporation, partnership or sole proprietorship that is 100% owned by any of the persons in (i) or (ii). In addition, a trustee or other fiduciary can count all shares purchased for a single trust, estate or other single fiduciary account that has multiple accounts (including one or more employee benefit plans of the same employer).

Class A Sales Charge Waivers

Class A shares of a Fund may be purchased at net asset value without a sales charge as follows:

· Purchases of $1,000,000 or more ($500,000 or more in the case of Nuveen Floating Rate Income Fund) (although such purchases may be subject to a CDSC in certain circumstances, see “What Share Classes We Offer—Contingent Deferred Sales Charges” above).


Section 3 How You Can Buy and Sell Shares	87

· Shares purchased through the reinvestment of Nuveen Mutual Fund dividends and capital gain distributions.

· Shares purchased for accounts held directly with a Fund that do not have a financial intermediary of record.

· Certain employer-sponsored retirement plans. Purchases by employer-sponsored retirement plans (“ESRPs”) as defined below, except that, in the case of ESRPs held through a brokerage account, Class A shares will be available at net asset value without a sales charge only if the broker-dealer has entered into an agreement with the Distributor that allows for such purchases. Intermediaries that have entered into such an agreement are listed in the appendix to this prospectus, “Variations in Sales Charge Reductions and Waivers Available Through Certain Intermediaries.”

For this purpose, ESRPs include, but are not limited to, 401(k) plans, 457 plans, employer-sponsored 403(b) plans, profit sharing and money purchase pension plans, health savings accounts, defined benefit plans, non-qualified deferred compensation plans, Roth 401(k) plans and Roth 403(b) plans, and do not include SEPs, SAR-SEPs, SIMPLE IRAs (other than SIMPLE IRAs opened before January 1, 2011 where the Distributor is the broker of record), SIMPLE 401(k) plans, Solo 401(k) plans, KEOGH plans, non-qualified deferred compensation plans and single defined benefit plans.

· Employees of Nuveen, LLC and its affiliates. Purchases by current and retired employees of Nuveen, LLC and its affiliates and such employees’ immediate family members (as defined in the statement of additional information).

· Current and former trustees/directors of the Nuveen Funds.

· Financial intermediary personnel. Purchases by any person who, for at least the last 90 days, has been an officer, director, or employee of any financial intermediary or any such person’s immediate family member.

· Certain trust departments. Purchases by bank or broker-affiliated trust departments investing funds over which they exercise exclusive discretionary investment authority and that are held in a fiduciary, agency, advisory, custodial or similar capacity.

· Additional categories of investors. Purchases made (i) by investors purchasing on a periodic fee, asset-based fee or no transaction fee basis through a broker-dealer sponsored mutual fund purchase program; (ii) by clients of investment advisers, financial planners or other financial intermediaries that charge periodic or asset-based fees for their services; and (iii) through a financial intermediary that has entered into an agreement with the Distributor to offer the Funds’ shares to self-directed investment brokerage accounts and that may or may not charge a transaction fee to its customers. Intermediaries that have entered into such an agreement are listed in the appendix to this prospectus, “Variations in Sales Charge Reductions and Waivers Available Through Certain Intermediaries.”

In order to obtain a sales charge reduction or waiver on Class A share purchases, it may be necessary at the time of purchase for you to inform the Funds or your financial advisor of the existence of other accounts in which there are holdings eligible to be aggregated for such purposes. You may need to provide the Funds or your financial advisor information or records, such as account statements, in order to verify your eligibility for a sales charge reduction or waiver. This may include account statements of family members and information regarding Nuveen Mutual Fund shares held in accounts with other financial advisors. You or your financial advisor must notify the Distributor at


88	Section 3 How You Can Buy and Sell Shares

the time of each purchase if you are eligible for any of these programs. The Funds may modify or discontinue these programs at any time.

CDSC Waivers and Reductions

The CDSC payable upon the redemption of Class C shares, and on Class A shares that were purchased at net asset value without a sales charge because the purchase amount exceeded $1,000,000 ($500,000 for Nuveen Floating Rate Income Fund), may be waived or reduced under the following circumstances:

· In the event of total disability of the shareholder.

· In the event of death of the shareholder.

· For certain redemptions made pursuant to a systematic withdrawal plan.

· For redemptions in connection with a payment of account or plan fees.

· For redemptions of accounts not meeting required minimum balances.

· Upon an optional conversion by a Fund of Class C shares held in an account which no longer has a financial intermediary of record into Class A shares.

· For redemptions of Class C shares where the Distributor did not advance the first year’s service and distribution fees to the intermediary.

· For redemptions of Class A shares where the Distributor did not pay a sales charge to the intermediary when the shares were purchased.

· For certain redemptions of shares held by an employer-sponsored qualified defined contribution plan.

· For certain redemptions of shares held in an IRA account, including redemptions to satisfy required minimum distributions from the account due to the shareholder reaching the qualified age based on applicable laws and regulations.

More information on these and other available CDSC waivers and reductions can be found in the appendix to this prospectus, “Variations in Sales Charge Reductions and Waivers Available Through Certain Intermediaries,” and in the statement of additional information.

How to Buy Shares

Fund shares may be purchased on any business day, which is any day the New York Stock Exchange (the “NYSE”) is open for business. Generally, the NYSE is closed on weekends and national holidays. The share price you pay depends on when the Distributor receives your order and on the share class you are purchasing. Orders received before the close of trading on a business day (normally, 4:00 p.m. New York time) will receive that day’s closing share price; otherwise, you will receive the next business day’s price.

You may purchase Fund shares (1) through a financial advisor or other financial intermediary or (2) directly from the Funds. Class A and Class C shares may not be purchased directly from a Fund. In addition, the availability of Class A and Class C shares through a financial intermediary will depend on the policies of the intermediary.

Through a Financial Advisor

You may buy shares through your financial advisor, who can handle all the details for you, including opening a new account. Financial advisors can also help you review your financial needs and formulate long-term investment goals and objectives. In addition,


Section 3 How You Can Buy and Sell Shares	89

financial advisors generally can help you develop a customized financial plan, select investments and monitor and review your portfolio on an ongoing basis to help assure your investments continue to meet your needs as circumstances change. Financial advisors (including brokers or agents) are paid for providing ongoing investment advice and services, either from Fund sales charges and fees or by charging you a separate fee in lieu of a sales charge.

Financial advisors or other dealer firms may charge their customers a processing or service fee in connection with the purchase or redemption of Fund shares. The amount and applicability of such a fee is determined and disclosed to customers by each individual dealer. Processing or service fees typically are fixed, nominal dollar amounts and are in addition to the sales and other charges described in this prospectus and the statement of additional information. Your dealer will provide you with specific information about any processing or service fees you will be charged. Shares you purchase through your financial advisor or other intermediary will normally be held with that firm. For more information, please contact your financial advisor.

Directly from the Funds

Eligible investors may purchase shares directly from the Funds.

· By wire. You can purchase shares by making a wire transfer from your bank. Before making an initial investment by wire, you must submit a new account form to a Fund. After receiving your form, a service representative will contact you with your account number and wiring instructions. Your order will be priced at the next closing share price based on the share class of your Fund, calculated after your Fund’s custodian receives your payment by wire. Wired funds must be received prior to 4:00 p.m. New York time to be eligible for same day pricing. Neither your Fund nor the transfer agent is responsible for the consequences of delays resulting from the banking or Federal Reserve wire system, or from incomplete wiring instructions. Before making any additional purchases by wire, you should call Nuveen Funds at (800) 257-8787. You cannot purchase shares by wire on days when federally chartered banks are closed.

· By mail. You may open an account directly with the Funds and buy shares by completing an application and mailing it along with your check to: Nuveen Funds, P.O. Box 219140, Kansas City, Missouri 64121-9140. Applications may be obtained at www.nuveen.com or by calling (800) 257-8787. No third party checks will be accepted.

Purchase orders and redemption requests are not processed until received in proper form by the transfer agent of a Fund.

· On-line. Existing shareholders with direct accounts may process certain account transactions on-line. You may purchase additional shares or exchange shares between existing, identically registered direct accounts. You can also look up your account balance, history and dividend information, as well as order duplicate account statements and tax forms from the Funds’ website. To access your account, click on the “Online Account Access” link under the “Individual Investors—Mutual Fund Account Access” heading at www.nuveen.com/client-access. The system will walk you through the log-in process. To purchase shares on-line, you must have established Fund Direct privileges on your account prior to the requested transaction. See “Special Services—Fund Direct” below.

· By telephone. Existing shareholders with direct accounts may also process account transactions via the Funds’ automated information line. Simply call (800) 257-8787,


90	Section 3 How You Can Buy and Sell Shares

press 1 for mutual funds and the voice menu will walk you through the process. To purchase shares by telephone, you must have established Fund Direct privileges on your account prior to the requested transaction. See “Special Services—Fund Direct” below.

The Distributor does not have a customer relationship with you solely by virtue of acting as principal underwriter and distributor for your Fund. The Distributor does not offer or provide investment monitoring, make investment decisions for you, or hold customer accounts or assets. You make the ultimate decision regarding whether to buy or sell any Nuveen Fund.

Special Services

To help make your investing with us easy and efficient, we offer you the following services at no extra cost. Your financial advisor can help you complete the forms for these services, or you can call Nuveen Funds at (800) 257-8787 for copies of the necessary forms.

Systematic Investing

Once you have opened an account satisfying the applicable investment minimum, systematic investing allows you to make regular additional investments through automatic deductions from your bank account, directly from your paycheck or from exchanging shares from another mutual fund account. The minimum automatic deduction is $100 per month. There is no charge to participate in your Fund’s systematic investment plan. You can stop the deductions at any time by notifying your Fund in writing.

· From your bank account. You can make systematic investments of $100 or more per month by authorizing your Fund to draw pre-authorized checks on your bank account.

· From your paycheck. With your employer’s consent, you can make systematic investments each pay period (collectively meeting the monthly minimum of $100) by authorizing your employer to deduct monies from your paycheck.

· Systematic exchanging. You can make systematic investments by authorizing the Distributor to exchange shares from one Nuveen Mutual Fund account into another identically registered Nuveen Mutual Fund account of the same share class.

Your Fund may cancel your participation in its systematic investment plan if it is unable to deliver a current prospectus to you because of an incorrect or invalid mailing address.

Systematic Withdrawal

If the value of your Fund account is at least $10,000, you may request to have $50 or more withdrawn automatically from your account. You may elect to receive payments monthly, quarterly, semi-annually or annually, and may choose to receive a check, have the monies transferred directly into your bank account (see “Fund Direct” below), paid to a third party or sent payable to you at an address other than your address of record. You must complete the appropriate section of the account application or Account Update Form to participate in each Fund’s systematic withdrawal plan.

You should not establish systematic withdrawals if you intend to make concurrent purchases of Class A or Class C shares because you may unnecessarily pay a sales charge or CDSC on these purchases.


Section 3 How You Can Buy and Sell Shares	91

Exchanging Shares

You may exchange Fund shares into an identically registered account for the same class of another Nuveen Mutual Fund available in your state. Your exchange must meet the minimum purchase requirements of the fund into which you are exchanging. You may also, under certain limited circumstances, exchange between certain classes of shares of the same fund, subject to the payment of any applicable CDSC. Please consult the statement of additional information for details.

Each Fund reserves the right to revise or suspend the exchange privilege, limit the amount or number of exchanges, or reject any exchange. In the event that a Fund rejects an exchange request, neither the redemption nor the purchase side of the exchange will be processed. If you would like the redemption request to be processed even if the purchase order is rejected, you may submit a separate redemption request (see “How to Sell Shares” below). Shareholders will be provided with at least 60 days’ notice of any material revision to or termination of the exchange privilege.

Because an exchange between funds is treated for tax purposes as a purchase and sale, any gain may be subject to tax. An exchange between classes of shares of the same fund may not be considered a taxable event. You should consult your tax advisor about the tax consequences of exchanging your shares.

Fund Direct^SM

The Fund Direct Program allows you to link your Fund account to your bank account, transfer money electronically between these accounts and perform a variety of account transactions, including purchasing shares by telephone and investing through a systematic investment plan. You may also have dividends, distributions, redemption payments or systematic withdrawal plan payments sent directly to your bank account.

Reinstatement Privilege

If you redeem Class A or Class C shares, you may reinvest all or part of your redemption proceeds up to one year later without incurring any additional charges. You may only reinvest into the same share class you redeemed. If you paid a CDSC, any shares purchased pursuant to the reinstatement privilege will not be subject to a CDSC. You may use this reinstatement privilege only once for any redemption.

How to Sell Shares

You may sell (redeem) your shares on any business day, which is any day the NYSE is open for business. You will receive the share price next determined after your Fund has received your properly completed redemption request. Your redemption request must be received before the close of trading (normally, 4:00 p.m. New York time) for you to receive that day’s price. The Fund will normally mail your check the next business day after a redemption request is received, but in no event more than seven days after your request is received. If you are selling shares purchased recently with a check, your redemption proceeds will not be mailed until your check has cleared, which may take up to ten business days from your purchase date.

You may sell your shares (1) through a financial advisor or (2) directly to the Funds.

Through a Financial Advisor

You may sell your shares through your financial advisor, who can prepare the necessary documentation. Your financial advisor may charge for this service.


92	Section 3 How You Can Buy and Sell Shares

Directly to the Funds

· By mail. You can sell your shares at any time by sending a written request to the appropriate Fund, c/o Nuveen Funds, P.O. Box 219140, Kansas City, Missouri 64121-9140. Your request must include the following information:

· The Fund’s name;

· Your name and account number;

· The dollar or share amount you wish to redeem;

· The signature of each owner exactly as it appears on the account;

· The name of the person to whom you want your redemption proceeds paid (if other than to the shareholder of record);

· The address where you want your redemption proceeds sent (if other than the address of record); and

· Any required signature guarantees.

After you have established your account, signatures on a written request must be guaranteed if:

· You would like redemption proceeds payable or sent to any person, address or bank account other than that on record;

· You have changed the address on your Fund’s records within the last 30 days;

· Your redemption request is in excess of $50,000; or

· You are requesting a change in ownership on your account.

Non-financial transactions, including establishing or modifying certain services such as changing bank information on an account, will require a signature guarantee or signature verification from a Medallion Signature Guarantee Program member or other acceptable form of authentication from a financial institution source. In addition to the situations described above, the Funds reserve the right to require a signature guarantee, or another acceptable form of signature verification, in other instances based on the circumstances of a particular situation.

A signature guarantee assures that a signature is genuine and protects shareholders from unauthorized account transfers. Banks, savings and loan associations, trust companies, credit unions, broker-dealers and member firms of a national securities exchange may guarantee signatures. Call your financial intermediary to determine if it has this capability. A notary public is not an acceptable signature guarantor. Proceeds from a written redemption request will be sent to you by check unless another form of payment is requested.

· On-line. You may redeem shares or exchange shares between existing, identically registered accounts on-line. To access your account, click on the “Online Account Access” link under the “Individual Investors—Mutual Fund Account Access” heading at www.nuveen.com/client-access. The system will walk you through the log-in process. Redemptions where the proceeds are payable by check may not exceed $50,000. Checks will only be issued to you as the shareholder of record and mailed to your address of record. If you have established Fund Direct privileges, you may have redemption proceeds transferred electronically to your bank account. In this case, the redemption proceeds will be transferred to your bank on the next business day after the redemption request is received. You should contact your bank for


Section 3 How You Can Buy and Sell Shares	93

further information concerning the timing of the credit of the redemption proceeds in your bank account.

· By telephone. If your account is held with your Fund and not in your brokerage account, and you have authorized telephone redemption privileges, call (800) 257-8787 to redeem your shares, press 1 for mutual funds and the voice menu will walk you through the process. Redemptions where the proceeds are payable by check may not exceed $50,000. Checks will only be issued to you as the shareholder of record and mailed to your address of record, normally the next business day after the redemption request is received. If you have established Fund Direct privileges, you may have redemption proceeds transferred electronically to your bank account. In this case, the redemption proceeds will be transferred to your bank on the next business day after the redemption request is received. You should contact your bank for further information concerning the timing of the credit of the redemption proceeds in your bank account.

An Important Note About Telephone Transactions

Although Nuveen Funds has certain safeguards and procedures to confirm the identity of callers, it will not be liable for losses resulting from following telephone instructions it reasonably believes to be genuine.

Also, you should verify your trade confirmations immediately upon receipt.

Accounts with Low Balances

A Fund reserves the right to liquidate or assess a low balance fee on any account (other than accounts holding Class R6 shares) held directly with the Fund that has a balance that has fallen below the account balance minimum of $1,000 for any reason, including market fluctuations.

If a Fund elects to exercise the right to assess a low balance fee, then annually the Fund will assess a $15 low balance account fee on certain accounts with balances under the account balance minimum that are IRAs, Coverdell Education Savings Accounts or accounts established pursuant to the UTMA or UGMA. At the same time, other accounts with balances under the account balance minimum will be liquidated, with proceeds being mailed to the address of record. Prior to the assessment of any low balance fee or liquidation of low balance accounts, affected shareholders will receive a communication notifying them of the pending action, thereby providing time for shareholders to bring their accounts up to the account balance minimum prior to any fee assessment or account liquidation. You will not be assessed a CDSC if your account is liquidated.

Meeting Redemption Requests

Each Fund typically will pay redemption proceeds using cash reserves maintained in the Fund’s portfolio, or using the proceeds from sales of portfolio securities. The Funds also may meet redemption requests through overdrafts at the Funds’ custodian, by borrowing under a credit agreement to which the Funds are parties, or by borrowing from another Nuveen Fund under an inter-fund lending program maintained by the Nuveen Funds pursuant to exemptive relief granted by the Securities and Exchange Commission. See “Investment Policies and Techniques—Borrowing” in the statement of additional information. These additional methods are more likely to be used to meet large redemption requests or in times of stressed market conditions.

Although the Funds generally pay redemption proceeds in cash, if a Fund determines that it would be detrimental to its remaining shareholders to make payment of a redemption order wholly in cash, that Fund may pay a portion of your redemption proceeds in securities or other Fund assets. In this situation, you would generally receive


94	Section 3 How You Can Buy and Sell Shares

a proportionate distribution of each security held by the Fund to the extent practicable. Although it is unlikely that your shares would be redeemed in-kind, you would probably have to pay brokerage costs to sell the securities or other assets distributed to you, as well as taxes on any capital gains from that sale. Until they are sold, any securities or other assets distributed to you as part of a redemption in-kind may be subject to market risk.


Section 3 How You Can Buy and Sell Shares	95

Section 4 General Information

To help you understand the tax implications of investing in the Funds, this section includes important details about how the Funds make distributions to shareholders. We discuss some other Fund policies as well. Please consult the statement of additional information and your tax advisor for more information about taxes.

Dividends, Distributions and Taxes

The Funds declare dividends daily and pay such dividends monthly. Your account will begin to accrue dividends on the business day after the day when the monies used to purchase your shares are collected by the transfer agent. Each Fund seeks to pay monthly dividends at a level rate that reflects the past and projected net income of the Fund. To help maintain more stable monthly distributions, the distribution paid by a Fund for any particular monthly period may be more or less than the amount of net income actually earned by the Fund during such period, and any such under- (or over-) distribution of income is reflected in the Fund’s net asset value. This policy is designed to result in the distribution of substantially all of the Funds’ net income over time. The Funds declare and pay any taxable capital gains once a year at year end. The Funds may declare and pay dividends, capital gains or other taxable distributions more frequently, if necessary or appropriate in the Board's discretion.

Payment and Reinvestment Options

The Funds automatically reinvest your dividends in additional Fund shares unless you request otherwise. You may request to have your dividends paid to you by check, sent via electronic funds transfer through Automated Clearing House network or reinvested in shares of another Nuveen Mutual Fund. For further information, contact your financial advisor or call Nuveen Funds at (800) 257-8787. If you request that your distributions be paid by check but those distributions cannot be delivered because of an incorrect mailing address, or if a distribution check remains uncashed for six months, the undelivered or uncashed distributions and all future distributions will be reinvested in Fund shares at the current net asset value.

Non-U.S. Income Tax Considerations

Investment income that a Fund receives from its non-U.S. investments may be subject to non-U.S. income taxes, which generally will reduce Fund distributions. However, the United States has entered into tax treaties with many non-U.S. countries that may entitle you to certain tax benefits.

If a Fund has more than 50% of the value of its assets in stock or other securities of non-U.S. corporations at the close of a taxable year, the Fund may, for such taxable year, elect to pass its non-U.S. tax credits through to shareholders.

Taxes and Tax Reporting

The Funds will make distributions that may be taxed as ordinary income (which may be taxable at different rates, depending on the sources of the distributions) or capital gains (which may be taxable at different rates, depending on the length of time a Fund holds its assets). Distributions from a Fund’s long-term capital gains are generally taxable as capital gains, while distributions from short-term capital gains and net investment income are generally taxable as ordinary income. However, certain ordinary income distributions


96	Section 4 General Information

received from a Fund that are determined to be qualified dividend income may be taxed at tax rates equal to those applicable to long-term capital gains. The tax you pay on a given capital gain distribution depends generally on how long the Fund has held the portfolio securities it sold and not on how long you have owned your Fund shares. Distributions generally do not qualify for a dividends received deduction if you are a corporate shareholder.

Early in each year, you will receive a statement detailing the amount and nature of all distributions that you were paid during the prior year. If you hold your investment at the firm where you purchased your Fund shares, you will receive the statement from that firm. If you hold your shares directly with the Fund, the Distributor will send you the statement. The tax status of your distributions is the same whether you reinvest them or elect to receive them in cash. The sale of shares in your account may produce a gain or loss, and is a taxable event. For tax purposes, an exchange of shares between funds is generally treated the same as a sale.

Please note that if you do not furnish your Fund with your correct Social Security number or employer identification number, you fail to provide certain certifications to your Fund, you fail to certify whether you are a U.S. citizen or a U.S. resident alien, or the Internal Revenue Service notifies the Fund to withhold, federal law requires your Fund to withhold federal income tax from your distributions and redemption proceeds at the applicable withholding rate.

Buying or Selling Shares Close to a Record Date

Buying Fund shares shortly before the record date for a taxable dividend or capital gain distribution is commonly known as “buying the dividend.” The entire distribution may be taxable to you even though a portion of the distribution effectively represents a return of your purchase price.

Non-U.S. Investors

The Funds are offered for sale in the United States and are not widely available outside the United States. Non-U.S. investors should be aware that U.S. withholding and estate taxes and certain U.S. tax reporting requirements may apply to any investment in a Fund.

Cost Basis Method

For shares acquired on or after January 1, 2012, you may elect a cost basis method to apply to all existing and future accounts you may establish. The cost basis method you select will determine the order in which shares are redeemed and how your cost basis information is calculated and subsequently reported to you and to the Internal Revenue Service. Please consult your tax advisor to determine which cost basis method best suits your specific situation. If you hold your account directly with a Fund, please contact Nuveen Funds at (800) 257-8787 for instructions on how to make your election. If you hold your account with a financial intermediary, please contact that financial intermediary for instructions on how to make your election. If you hold your account directly with a Fund and do not elect a cost basis method, your account will default to the average cost basis method. The average cost basis method generally calculates cost basis by determining the average price paid for Fund shares that may have been purchased at different times for different prices. Financial intermediaries choose their own default cost basis method.


Section 4 General Information	97

Distribution and Service Payments

Distribution and Service Plan

The Distributor serves as the selling agent and distributor of the Funds’ shares. In this capacity, the Distributor manages the offering of the Funds’ shares and is responsible for all sales and promotional activities. In order to reimburse the Distributor for its costs in connection with these activities, including compensation paid to financial intermediaries, each Fund has adopted a distribution and service plan under Rule 12b-1 under the 1940 Act (the “Plan”). See “How You Can Buy and Sell Shares—What Share Classes We Offer” for a description of the distribution and service fees paid under the Plan.

Under the Plan, the Distributor receives a distribution fee for Class C shares primarily for providing compensation to financial intermediaries, including the Distributor, in connection with the distribution of shares. The Distributor receives a service fee for Class A and Class C shares to compensate financial intermediaries, including the Distributor, for providing ongoing account services to shareholders. These services may include establishing and maintaining shareholder accounts, answering shareholder inquiries and providing other personal services to shareholders. Fees paid under the Plan also compensate the Distributor for other expenses, including printing and distributing prospectuses to persons other than shareholders, and preparing, printing, and distributing advertising materials, sales literature and reports to shareholders used in connection with the sale of shares. Because fees paid under the Plan are paid out of a Fund’s assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges. Long-term holders of Class C shares may pay more in distribution and service fees and CDSCs than the economic equivalent of the maximum front-end sales charge permitted under the Financial Industry Regulatory Authority Conduct Rules.

Other Payments by the Funds

In addition to the distribution and service fees the Funds pay under the Plan and fees the Funds pay to their transfer agent, the Distributor or Nuveen Fund Advisors, on behalf of the Funds, may enter into non-Plan agreements with financial intermediaries pursuant to which the Funds will pay financial intermediaries for administrative, networking, recordkeeping, sub-transfer agency and shareholder services. These non-Plan payments are generally based on either (1) a percentage of the average daily net assets of Fund shareholders serviced by a financial intermediary or (2) a fixed dollar amount for each account serviced by a financial intermediary. The aggregate amount of these payments may be substantial and may vary significantly among intermediaries.

Other Payments by the Distributor and Nuveen Fund Advisors

In addition to the sales commissions and payments from distribution and service fees made to financial intermediaries as previously described, the Distributor and Nuveen Fund Advisors may from time to time make additional payments, out of their own resources, to certain financial intermediaries that sell shares of Nuveen Mutual Funds in order to promote the sales and retention of Fund shares by those firms and their customers. The amounts of these payments vary by financial intermediary and, with respect to a given firm, are typically calculated by reference to the amount of the firm’s recent gross sales of Nuveen Mutual Fund shares and/or total assets of Nuveen Mutual Funds held by the firm’s customers. The level of payments that the Distributor and/or Nuveen Fund Advisors is willing to provide to a particular financial intermediary may be affected by, among other factors, the firm’s total assets held in and recent net investments into Nuveen Mutual Funds, the firm’s level of participation in Nuveen Mutual


98	Section 4 General Information

Fund sales and marketing programs, the firm’s compensation program for its registered representatives who sell Nuveen Mutual Fund shares and provide services to Nuveen Mutual Fund shareholders, and the asset class of the Nuveen Mutual Funds for which these payments are provided. The statement of additional information contains additional information about these payments, including the names of the firms to which payments are made. The Distributor may also make payments to financial intermediaries in connection with sales meetings, due diligence meetings, prospecting seminars and other meetings at which the Distributor promotes its products and services.

In connection with the availability of Nuveen Mutual Funds within selected mutual fund no-transaction fee institutional platforms and fee-based wrap programs at certain financial intermediaries, the Distributor and Nuveen Fund Advisors also make payments out of their own assets to those firms as compensation for certain recordkeeping, shareholder communications and other account administration services provided to Nuveen Mutual Fund shareholders who own their Fund shares through these platforms or programs. These payments are in addition to the service fee and any applicable sub-transfer agency or similar fees paid to these firms with respect to these services by the Nuveen Mutual Funds out of Fund assets.

The amounts of payments to a financial intermediary could be significant, and may create an incentive for the intermediary or its representatives to recommend or offer shares of the Funds to you. The intermediary may elevate the prominence or profile of the Funds within the intermediary’s organization by, for example, placing the Funds on a list of preferred or recommended funds and/or granting the Distributor and/or its affiliates preferential or enhanced opportunities to promote the Funds in various ways within the intermediary’s organization.

There is some uncertainty concerning whether the types of payments described above may be made to or received by a financial intermediary with respect to Class I shares offered through the intermediary’s brokerage platform where the intermediary imposes commissions on purchases and redemptions of such shares. Such payments may be terminated in light of future regulatory developments.

Net Asset Value

The price you pay for your shares or the amount you receive upon redemption of your shares is based on your Fund’s net asset value per share, which is determined as of the close of trading (normally 4:00 p.m. New York time) on each day the NYSE is open for business. Each Fund’s latest net asset value per share is available on the Funds’ website at www.nuveen.com. Net asset value is calculated for each class of each Fund by taking the value of the class’s total assets, including interest or dividends accrued but not yet collected, less all liabilities, and dividing by the total number of shares outstanding. The result, rounded to the nearest cent, is the net asset value per share.

In determining net asset value, portfolio instruments traded on an exchange generally are valued at the last reported sales price or official closing price on the exchange, if available. If such market quotations are not readily available or are not considered reliable, a portfolio instrument will be valued at its fair value as determined in good faith using procedures approved by Nuveen Fund Advisors, subject to the oversight of the Board of Directors/Trustees. For example, the fair value of a portfolio instrument may be determined using prices provided by independent pricing services or obtained from other sources, such as broker-dealer quotations. Independent pricing services typically value non-exchange-traded instruments utilizing a range of market-based inputs and assumptions. For example, when available, pricing services may utilize inputs such as


Section 4 General Information	99

benchmark yields, reported trades, broker-dealer quotes, spreads, and transactions for comparable instruments. In pricing certain instruments, the pricing services may consider information about an instrument’s issuer or market activity provided by the Funds’ investment adviser or sub-adviser. Pricing service valuations of non-exchange-traded instruments represent the service’s good faith opinion as to what the holder of an instrument would receive in an orderly transaction for an institutional round lot position under current market conditions. It is possible that these valuations could be materially different from the value that a Fund realizes upon the sale of an instrument. Non-U.S. securities and currency are valued in U.S. dollars based on non-U.S. currency exchange rate quotations supplied by an independent quotation service.

For non-U.S. traded securities whose principal local markets close before the close of the NYSE, a Fund may adjust the local closing price based upon such factors as developments in non-U.S. markets, the performance of U.S. securities markets and the performance of instruments trading in U.S. markets that represent non-U.S. securities. A Fund may rely on an independent fair valuation service in making any such fair value determinations. If a Fund holds portfolio instruments that are primarily listed on non-U.S. exchanges, the value of such instruments may change on days when shareholders will not be able to purchase or redeem the Fund’s shares.

The price of a portfolio instrument may be determined unreliable in various circumstances. For example, a price may be deemed unreliable if it has not changed for an identified period of time, or has changed from the previous day’s price by more than a threshold amount, and recent transactions and/or broker dealer price quotations differ materially from the price in question.

The Board of Directors/Trustees has designated Nuveen Fund Advisors as the Funds’ valuation designee pursuant to Rule 2a-5 under the 1940 Act and delegated to Nuveen Fund Advisors the day-to-day responsibility of making fair value determinations. All fair value determinations are made in accordance with procedures adopted by Nuveen Fund Advisors, subject to the oversight of the Board of Directors/Trustees. As a general principle, the fair value of a portfolio instrument is the amount that an owner might reasonably expect to receive upon the instrument’s current sale. A range of factors and analysis may be considered when determining fair value, including relevant market data, interest rates, credit considerations and/or issuer specific news. However, fair valuation involves subjective judgments and it is possible that the fair value determined for a portfolio instrument may be materially different from the value that could be realized upon the sale of that instrument.

Frequent Trading

The Funds are intended for long-term investment and should not be used for excessive trading. Excessive trading in the Funds’ shares can disrupt portfolio management, lead to higher operating costs, and cause other operating inefficiencies for the Funds. However, the Funds are also mindful that shareholders may have valid reasons for periodically purchasing and redeeming Fund shares.

Accordingly, the Funds have adopted a Frequent Trading Policy that seeks to balance the Funds’ need to prevent excessive trading in Fund shares while offering investors the flexibility in managing their financial affairs to make periodic purchases and redemptions of Fund shares.

The Funds’ Frequent Trading Policy generally limits an investor to two “round trip” trades in a 60-day period. A “round trip” is the purchase and subsequent redemption of Fund


100	Section 4 General Information

shares, including by exchange. Each side of a round trip may be comprised of either a single transaction or a series of closely-spaced transactions.

The Funds primarily receive share purchase and redemption orders through third-party financial intermediaries, some of whom rely on the use of omnibus accounts. An omnibus account typically includes multiple investors and provides the Funds only with a net purchase or redemption amount on any given day where multiple purchases, redemptions and exchanges of shares occur in the account. The identity of individual purchasers, redeemers and exchangers whose orders are aggregated in omnibus accounts, and the size of their orders, will generally not be known by the Funds. Despite the Funds’ efforts to detect and prevent frequent trading, the Funds may be unable to identify frequent trading because the netting effect in omnibus accounts often makes it more difficult to identify frequent traders. The Distributor has entered into agreements with financial intermediaries that maintain omnibus accounts with the Funds’ transfer agent. Under the terms of these agreements, the financial intermediaries undertake to cooperate with the Distributor in monitoring purchase, exchange and redemption orders by their customers in order to detect and prevent frequent trading in the Funds through such accounts. Pursuant to these agreements, financial intermediaries may disclose to a Fund an investor’s taxpayer identification number and a record of the investor’s transactions at the request of the Fund. Technical limitations in operational systems at such intermediaries or at the Distributor may also limit the Funds’ ability to detect and prevent frequent trading. In addition, the Funds may permit certain financial intermediaries, including broker-dealer and retirement plan administrators, among others, to enforce their own internal policies and procedures concerning frequent trading. Such policies may differ from the Funds’ Frequent Trading Policy and may be approved for use in instances where the Funds reasonably believe that the intermediary’s policies and procedures effectively discourage inappropriate trading activity. Shareholders holding their accounts with such intermediaries may wish to contact the intermediary for information regarding its frequent trading policy. Although the Funds do not knowingly permit frequent trading, they cannot guarantee that they will be able to identify and restrict all frequent trading activity.

The Funds reserve the right in their sole discretion to waive unintentional or minor violations (including transactions below certain dollar thresholds) if they determine that doing so would not harm the interests of Fund shareholders. In addition, certain categories of redemptions may be excluded from the application of the Frequent Trading Policy, as described in more detail in the statement of additional information. These include, among others, redemptions pursuant to systematic withdrawal plans, redemptions in connection with the total disability or death of the investor, involuntary redemptions by operation of law, redemptions in payment of account or plan fees, and certain redemptions by retirement plans, including redemptions in connection with qualifying loans or hardship withdrawals, termination of plan participation, return of excess contributions, and required minimum distributions. The Funds may also modify or suspend the Frequent Trading Policy without notice during periods of market stress or other unusual circumstances.

The Funds reserve the right to impose restrictions on purchases or exchanges that are more restrictive than those stated above if they determine, in their sole discretion, that a transaction or a series of transactions involves market timing or excessive trading that may be detrimental to Fund shareholders. The Funds also reserve the right to reject any purchase order, including exchange purchases, for any reason. For example, a Fund may refuse purchase orders if the Fund would be unable to invest the proceeds from the purchase order in accordance with the Fund’s investment policies and/or objective, or if

the Fund would be adversely affected by the size of the transaction, the frequency of trading in the account or various other factors. For more information about the Funds’ Frequent Trading Policy and its enforcement, see “Purchase and Redemption of Fund Shares—Frequent Trading Policy” in the statement of additional information.

Appendix to the Prospectus

VARIATIONS IN SALES CHARGE REDUCTIONS AND WAIVERS
AVAILABLE THROUGH CERTAIN INTERMEDIARIES

A-1

The availability of certain sales charge variations, waivers and discounts will depend on whether you purchase your shares directly from a Fund or through a financial intermediary. Financial intermediaries may impose different sales charges and have unique policies and procedures regarding the availability of sales charge waivers and/or discounts (including based on account type), which differ from those described in the prospectus and are disclosed below. All sales charges and sales charge variations, waivers and discounts available to investors, other than those set forth below, are described in the prospectus. To the extent a financial intermediary notifies Nuveen Fund Advisors, LLC (“Nuveen Fund Advisors” or the “Adviser”) or Nuveen Securities, LLC (the “Distributor”) of its intention to impose sales charges or have sales charge waivers and/or discounts that differ from those described in the prospectus, such information provided by that intermediary will be disclosed in this Appendix.

In all instances, it is your responsibility to notify your financial intermediary at the time of purchase of any relationship or other facts qualifying you for sales charge waivers or discounts. Please contact your financial intermediary with questions regarding your eligibility for applicable sales charge variations, waivers and discounts or for additional information regarding your intermediary’s policies for implementing particular sales charge variations, waivers and discounts. For waivers and discounts not available through a particular financial intermediary, shareholders will have to purchase shares directly from a Fund or through another intermediary to receive these waivers or discounts.

The information provided below for a particular financial intermediary is reproduced based on information provided by that intermediary. A financial intermediary’s administration and implementation of its particular policies with respect to any variations, waivers and/or discounts is neither supervised nor verified by the Funds, the Adviser or the Distributor.

As used below, the phrase “Nuveen-sponsored mutual fund(s)” means any mutual fund for which Nuveen Fund Advisors serves as the investment adviser.

CLASS A SHARE FRONT-END SALES CHARGE WAIVERS AVAILABLE AT AMERIPRISE FINANCIAL

The following information applies to Class A share purchases if you have an account with or otherwise purchase Fund shares through Ameriprise Financial:

Shareholders purchasing Fund shares through an Ameriprise Financial platform or account will be eligible only for the following front-end sales charge waivers with respect to Class A shares, which may differ from those disclosed elsewhere in this Fund’s prospectus or SAI.

· Employer-sponsored retirement plans (e.g., 401(k) plans, 457 plans, employer-sponsored 403(b) plans, profit sharing and money purchase pension plans and defined benefit plans). For purposes of this provision, employer-sponsored retirement plans do not include SEP IRAs, Simple IRAs or SAR-SEPs.

· Shares purchased through reinvestment of capital gain distributions and dividend reinvestment when purchasing shares of the same Fund (but not any other Nuveen-sponsored mutual fund).

· Shares exchanged from Class C shares of the same fund in the month of or following the seven-year anniversary of the purchase date.

EDWARD D. JONES & CO., L.P. (“EDWARD JONES”)

Policies Regarding Transactions Through Edward Jones

The following information has been provided by Edward Jones:

Effective on or after January 1^st, 2024, the following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as "shareholders") purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as "breakpoints") and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information (“SAI”) or through another broker-dealer. In all instances, it is the shareholder's responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of Nuveen-sponsored mutual funds, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.

Breakpoints

· Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the prospectus.

Rights of Accumulation (“ROA”)

· The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of Nuveen-sponsored mutual fund assets held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations ("pricing groups"). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible Nuveen-sponsored mutual fund assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.

· The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.

· ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).

Letter of Intent (“LOI”)

· Through an LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of

A-4

eligible Nuveen-sponsored mutual fund assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if the LOI is not met.

· If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.

Sales Charge Waivers

Sales charges are waived for the following shareholders and in the following situations:

· Associates of Edward Jones and its affiliates and other accounts in the same pricing group (as determined by Edward Jones under its policies and procedures) as the associate. This waiver will continue for the remainder of the associate's life if the associate retires from Edward Jones in good-standing and remains in good standing pursuant to Edward Jones’ policies and procedures.

· Shares purchased in an Edward Jones fee-based program.

· Shares purchased through reinvestment of capital gains distributions and dividend reinvestment.

· Shares purchased from the proceeds of redeemed shares of a Nuveen-sponsored mutual fund so long as the following conditions are met: the proceeds are from the sale of shares within 60 days of the purchase, the sale and purchase are made from a share class that charges a front load, and one of the following:

o The redemption and repurchase occur in the same account.

o The redemption proceeds are used to process an: IRA contribution, excess contributions, conversion, recharacterizing of contributions, or distribution, and the repurchase is done in an account within the same Edward Jones grouping for ROA.

· Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of Edward Jones. Edward Jones is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.

· Exchanges from Class C shares to Class A shares of the same fund, generally, in the 84^th month following the anniversary of the purchase date or earlier at the discretion of Edward Jones.

Contingent Deferred Sales Charge (“CDSC”) Waivers

If the shareholder purchases shares that are subject to a CDSC and those shares are redeemed before the CDSC is expired, the shareholder is responsible to pay the CDSC except in the following conditions:

· The death or disability of the shareholder.

· Systematic withdrawals with up to 10% per year of the account value.

· Return of excess contributions from an Individual Retirement Account (IRA).

· Shares redeemed as part of a required minimum distribution for IRA and retirement accounts if the redemption is taken in or after the year the shareholder reaches qualified age based on applicable IRS regulations.

PFS INVESTMENTS INC. (“PFSI”)

Policies Regarding Fund Purchases Through PFSI

The following information supersedes all prior information with respect to transactions and positions held in fund shares purchased through PFSI and held on the mutual fund platform of its affiliate, Primerica Shareholder Services (“PSS”). Clients of PFSI (also referred to as “shareholders”) purchasing fund shares on the PSS platform are eligible only for the following share classes, sales charge discounts (also referred to as “breakpoints”) and waivers, which can differ from share classes, discounts and waivers described elsewhere in this prospectus or the related statement of additional information (“SAI”) or through another broker-dealer. In all instances, it is the shareholder’s responsibility to inform PFSI at the time of a purchase of all holdings of Nuveen Funds on the PSS platform, or other facts qualifying the purchaser for discounts or waivers. PFSI may request reasonable documentation of such facts and condition the granting of any discount or waiver on the timely receipt of such documents. Shareholders should contact PSS if they have questions regarding their eligibility for these discounts and waivers.

Share Classes

· Class A shares are available only to non-retirement accounts, individual retirement accounts (IRA), SEP IRAs, SIMPLE IRAs, Keogh Plans, and all other account types.

· Class C shares are available only to accounts with existing Class C share holdings.

Breakpoints

· Breakpoint pricing at dollar thresholds as described in the prospectus of the fund you are purchasing.

Rights of Accumulation (“ROA”)

· The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except any assets held in group retirement plans) of Nuveen Funds held by the shareholder on the PSS Platform. The inclusion of eligible Nuveen Fund assets in the ROA calculation is dependent on the shareholder notifying PFSI of such assets at the time of calculation. Shares of money market funds are included only if such shares were acquired in exchange for shares of another Nuveen Fund purchased with a sales charge. No shares of Nuveen Funds held by the shareholder away from the PSS platform will be granted ROA with shares of any Nuveen Fund purchased on the PSS platform.

· Any SEP IRA plan, any SIMPLE IRA plan or any Payroll Deduction plan (“PDP”) on the PSS platform will be defaulted to plan-level grouping for purposes of ROA, which allows each participating employee ROA with all other eligible shares held in plan accounts on the PSS platform. At any time, a participating employee may elect to exercise a one-time option to change grouping for purposes of ROA to shareholder- level grouping, which allows the plan account of the electing employee ROA with her other eligible holdings on the PSS platform, but not with all

A-11

other eligible participant holdings in the plan. Eligible shares held in plan accounts electing shareholder-level grouping will not be available for purposes of ROA to plan accounts electing plan-level grouping.

· ROA is determined by calculating the higher of cost minus redemptions or current market value (current shares multiplied by Fund NAV).

Letter of Intent (“LOI”)

· By executing a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period through PFSI, from the date PSS receives the LOI. The purchase price of the LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the dollar amount the shareholder intends to invest over a 13-month period to arrive at total investment for purposes of determining any breakpoint discount and the applicable front-end sales charge. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the projected total investment.

· Only holdings of Nuveen Funds on the PSS platform are eligible for inclusion in the LOI calculation and the shareholder must notify PFSI of all eligible assets at the time of calculation.

· Purchases made before the LOI is received by PSS are not adjusted under the LOI, and the LOI will not reduce any sales charge previously paid. Sales charges will be automatically adjusted if the total purchases required by the LOI are not met.

· If an employer maintaining a SEP IRA plan, SIMPLE IRA plan or non-IRA PDP on the PSS platform has elected to establish or change ROA for the accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer. LOIs are not available to PDP IRA plans on the PSS platform with plan-level grouping for purposes of ROA but are available to any participating employee that elects shareholder-level grouping for purposes of ROA.

Sales Charge Waivers

Sales charges are waived for the following shareholders and in the following situations:

· Shares purchased through reinvestment of capital gains distributions and dividend reinvestment.

Automated transactions (i.e. systematic purchases and withdrawals), full or partial transfers or rollovers of retirement accounts, and purchases made after shares are automatically sold to pay account maintenance fees are not eligible for this sales charge waiver.

· Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of PFSI.
