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 alphabetically, include:

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.

Currency Risk —Changes in currency exchange rates will affect the value of non-U.S. dollar denominated 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.

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 or a financial intermediary to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers 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. 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.

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.

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.

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.

Infrastructure Sector Risk —Because the Fund invests significantly in infrastructure-related securities, the Fund has greater exposure to adverse economic, regulatory, political, legal and other changes affecting the issuers of such securities. Additionally, infrastructure-related entities may be subject to regulation by various governmental authorities

Section 1     Fund Summaries

and affected by government regulation of rates charged to consumers, service interruptions or the imposition of special tariffs and changes in tax law.

Master Limited Partnership Risk —An investment in an MLP 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.

Non-U.S./Emerging Markets 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 and different legal, regulatory and tax environments. These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries as such countries may have a higher degree of economic instability, unsettled securities laws and inconsistent regulatory systems.

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 limited liquidity, changing or unfavorable tax treatments and possibly being issued by companies in heavily regulated industries.

Real Estate Investment Risk —The real estate industry has been subject to substantial fluctuations and declines on a local, regional and national basis in the past that may continue to occur in the future. Also, the value of a REIT can be hurt by economic downturns or by changes in real estate values, rents, property taxes, interest rates, tax treatment, regulations, or the legal structure of the REIT. By investing in REITs through the Fund, you bear both your proportionate share of Fund expenses and, indirectly, the expenses of the REITs in which the Fund invests.

Small- and Mid-Cap Stock Risk —Small-cap stocks involve substantial risk. Prices of small-cap stocks may be subject to more abrupt or erratic movements, and to wider fluctuations, than stock prices of larger, more established companies or the market averages in general. It may be difficult to sell small-cap stocks at the desired time and price. While mid-cap stocks may be slightly less volatile than small-cap stocks, they still involve similar risks.

Bond Market Liquidity Risk —Dealer inventories of bonds, which provide an indication of the ability of financial intermediaries to “make markets” in those bonds, are at or near historic lows in relation to market size. This reduction in market making capacity has the potential to decrease liquidity and increase price volatility in the fixed income markets in which the Fund invests, particularly during periods of economic or market stress. In addition, recent federal banking regulations may cause certain dealers to reduce their inventories of bonds, which may further decrease the Fund’s ability to buy or sell bonds. 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 bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices and hurt performance.

Call Risk —If, during periods of falling interest rates, an issuer calls higher-yielding debt instruments held by the Fund, the Fund may have to reinvest in securities with lower yields, which may adversely impact the Fund’s performance.

Convertible Security Risk —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.

Credit Risk —Credit risk is the risk that an issuer of a debt security may 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.

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. dollar denominated 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.

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 or a financial intermediary to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers 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. 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.

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.

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.

Section 1     Fund Summaries

ETN Risk —Like other index-tracking instruments, ETNs are subject to the risk that the value of the index may decline, at times sharply and unpredictably. In addition, ETNs—which are debt instruments—are subject to risk of default by the issuer.

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.

High Yield Securities Risk —High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities.

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.

Infrastructure Sector Risk —Because the Fund invests significantly in infrastructure-related securities, the Fund has greater exposure to adverse economic, regulatory, political, legal and other changes affecting the issuers of such securities. Additionally, infrastructure-related entities may be subject to regulation by various governmental authorities and affected by government regulation of rates charged to consumers, service interruptions or the imposition of special tariffs and changes in tax law.

Interest Rate Risk —Interest rate risk is the risk that the value of the Fund’s portfolio will decline because of rising interest rates. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities. Rising interest rates also may lengthen the duration of debt 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.

Master Limited Partnership Risk —An investment in an MLP 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. 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.

Non-U.S./Emerging Markets 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 and different legal, regulatory and tax environments. These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries as such countries may have a higher degree of economic instability, unsettled securities laws and inconsistent regulatory systems.

Other Investment Companies and Pooled Investment Vehicles Risk —When the Fund invests in other investment companies or pooled investment vehicles, including ETFs, you bear both your proportionate share of Fund expenses and, indirectly, the expenses of the other investment companies or pooled investment vehicles. Furthermore, the Fund is exposed to the risks to which the other investment companies or pooled investment vehicles 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 limited liquidity, changing or unfavorable tax treatments and possibly being issued by companies in heavily regulated industries.

Real Estate Investment Risk —The real estate industry has been subject to substantial fluctuations and declines on a local, regional and national basis in the past that may continue to occur in the future. Also, the value of a REIT can be

hurt by economic downturns or by changes in real estate values, rents, property taxes, interest rates, tax treatment, regulations, or the legal structure of the REIT. By investing in REITs through the Fund, you bear both your proportionate share of Fund expenses and, indirectly, the expenses of the REITs in which the Fund invests.

Rule 144A Securities Risk —The market for Rule 144A securities typically is less active than the market for publicly-traded securities. Rule 144A securities carry the risk that their liquidity may become impaired and the Fund may be unable to dispose of the securities promptly or at reasonable prices.

Small- and Mid-Cap Stock Risk —Small-cap stocks involve substantial risk. Prices of small-cap stocks may be subject to more abrupt or erratic movements, and to wider fluctuations, than stock prices of larger, more established companies or the market averages in general. It may be difficult to sell small-cap stocks at the desired time and price. While mid-cap stocks may be slightly less volatile than small-cap stocks, they still involve similar risks.

Valuation Risk —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 readily available market 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 sell a portfolio security at the price established by the pricing service, which could result in a 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. Different 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 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.

A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund’s portfolio.

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 or a financial intermediary to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers 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.

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.

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.

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.

It may be difficult to sell small-cap stocks at the desired time and price. While mid-cap stocks may be slightly less volatile than small-cap stocks, they still involve similar risks.

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 may also adversely affect the ability of a fund to achieve its investment goal.

Bond market liquidity risk: Primary dealer inventories of bonds appear to be low relative to the size of the fixed income market. These inventories are a core indication of dealers’ capacity to “make a market” in fixed income securities. This reduction in market making capacity has the potential to decrease liquidity and increase price volatility in the fixed income 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 bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices and hurt performance.

Call risk: Debt securities are subject to 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

Section 2     How We Manage Your Money

29

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, resulting in a decline in the fund’s income.

Convertible security risk : Convertible securities have characteristics of both equity and debt securities and, as a result, are exposed to certain additional risks that are typically associated with debt. 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.

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.

Credit risk: Credit risk is the risk that an issuer of a debt security held by a fund may be unable or unwilling to make interest and principal payments 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. Debt securities are subject to varying degrees of credit risk, which are often reflected in credit ratings. The credit rating of a debt security may be lowered 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, and can also affect the bond’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.

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 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.

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,

30

Section 2     How We Manage Your Money

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, or other service providers to incur regulatory penalties, reputational damage, additional compliance costs or financial loss. In addition, such incidents could affect issuers in which a fund invests, and thereby cause the fund’s investments to lose value.

Derivatives risk: The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. 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.

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 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.

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).

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.

Section 2     How We Manage Your Money

31

Equity security risk: Equity securities in a fund’s portfolio may decline significantly in price over short or extended periods of time. 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.

ETF risk: 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 a 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.

ETN risk: Like other index-tracking instruments, ETNs are subject to the risk that the value of the index may decline, at times sharply and unpredictably. In addition, ETNs—which are debt instruments—are subject to risk of default by the issuer. This is the major distinction between ETFs and ETNs: while ETFs are subject to market risk, ETNs are subject to both market risk and the risk of default by the issuer. ETNs are also subject to the risk that a liquid secondary market for any particular ETN might not be established or maintained.

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 usually offer higher yields than investment grade securities, but also involve more risk. 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 and carry more risk to principal. In addition, high yield securities generally are less liquid than investment grade securities.

Income risk: A fund’s income from its debt securities 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 debt securities (or portfolio securities that have been called, see “Call risk” above, or prepaid, see “Mortgage-backed securities risk” below), in lower-yielding securities. In addition, a fund’s income could decline when the fund experiences defaults on debt securities it holds.

Infrastructure sector risk: A fund that invests significantly in infrastructure-related securities has greater exposure to adverse economic, regulatory, political, legal, and other changes affecting the issuers of such securities. Infrastructure-related businesses are subject to a variety of factors that may adversely affect their business or operations, including high interest costs in

32

Section 2     How We Manage Your Money

connection with capital construction programs, costs associated with environmental and other regulations, the effects of economic slowdown and surplus capacity, increased competition from other providers of services, uncertainties concerning the availability of fuel at reasonable prices, the effects of energy conservation policies and other factors. Additionally, infrastructure-related entities may be subject to regulation by various governmental authorities and may also be affected by governmental regulation of rates charged to consumers, service interruption and/or legal challenges due to environmental, operational or other mishaps and the imposition of special tariffs and changes in tax laws, regulatory policies and accounting standards. There is also the risk that corruption may negatively affect publicly-funded infrastructure projects, especially in emerging markets, resulting in delays and cost overruns.

Interest rate risk: Debt securities held by a fund will fluctuate in value with changes in interest rates. In general, debt securities will increase in value when interest rates fall and decrease in value when interest rates rise. A fund may be subject to a greater risk of rising interest rates than would normally be the case due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. Longer-term debt securities are generally more sensitive to interest rate changes. Rising interest rates also may lengthen the duration of debt 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.

MLP risk: An MLP is an investment that combines the tax benefits of a limited partnership with the liquidity of publicly-traded securities. The risks of investing in an MLP are generally those involved in investing in a partnership as opposed to a corporation. For example, state law governing partnerships is often less restrictive than state law governing corporations. Accordingly, there may be fewer protections afforded investors in an MLP than investors in a corporation.

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. MLPs may have limited financial resources, their securities may trade infrequently and in limited volume, and they may be subject to more abrupt or erratic price movements than securities of larger or more broadly-based companies. A 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 reduction of the value of a fund’s investment in the MLP and lower income to the fund. Additionally, since MLPs generally conduct business in multiple states, a fund may be subject to income or franchise tax in each of the states in which the partnership does business.

Section 2     How We Manage Your Money

33

The additional cost of preparing and filing the tax returns and paying the related taxes may adversely impact a fund’s return on its investment in MLPs.

Mortgage-backed securities risk: The value of mortgage-backed securities can fall if the owners of the underlying mortgages pay off their mortgages sooner than expected, which could happen when interest rates fall or for other reasons.

Mortgage-backed securities 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, which would, in effect, convert a short- or medium-duration mortgage-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.

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.

Non-U.S./emerging markets 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, 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.

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:

34

Section 2     How We Manage Your Money

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

Preferred security risk: There are special risks associated with investing in preferred securities:

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.

Section 2     How We Manage Your Money

35

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.

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.

Real estate investment risk: Real estate companies have been subject to substantial fluctuations and declines on a local, regional and national basis in the past that may continue to occur in the future. Real property values and incomes from real property may decline due to general and local economic conditions, overbuilding and increased competition, increases in property

36

Section 2     How We Manage Your Money

taxes and operating expenses, changes in zoning laws, low demand, casualty or condemnation losses, regulatory limitations on rents, changes in neighborhoods and in demographics, increases in market interest rates, or other factors. Factors such as these may adversely affect companies which own and operate real estate directly, companies which lend to them, and companies which service the real estate industry.

Equity REITs will be affected by changes in the values of and incomes from the properties they own, while mortgage REITs may be affected by the credit quality of the mortgage loans they hold. REITs are subject to other risks as well, including the fact that REITs are dependent on specialized management skills which may affect their ability to generate cash flow for operating purposes and to make distributions to shareholders or unitholders. REITs may have limited diversification and are subject to the risks associated with obtaining financing for real property.

A U.S. domestic REIT can pass its income through to shareholders or unitholders without any tax at the entity level if it complies with various requirements under the Internal Revenue Code. There is the risk that a REIT held by a fund will fail to qualify for this tax-free pass-through treatment of its income. Similarly, REITs formed under the laws of non-U.S. countries may fail to qualify for corporate tax benefits made available by the governments of such countries.

By investing in REITs indirectly through a fund, in addition to bearing a proportionate share of the expenses of the fund, shareholders of the fund will also indirectly bear similar expenses of the REITs in which the fund invests.

Rule 144A s ecurities r isk: The market for Rule 144A securities typically is less active than the market for publicly-traded securities. Rule 144A securities carry the risk that their liquidity may become impaired and a fund may be unable to dispose of the securities promptly or at reasonable prices.

Small- and mid-cap stock risk: Stocks of small-cap companies involve substantial risk. These companies may lack the management expertise, product diversification, and competitive strengths of larger companies. They may have limited access to financial resources and may not have the financial strength to sustain them through business downturns or adverse market conditions. Since small-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. Prices of small-cap stocks may be subject to more abrupt or erratic movements than stock prices of larger, more established companies or the market averages in general. In addition, the frequency and volume of their trading may be less than is typical of larger companies, making them subject to wider price fluctuations. In some cases, there could be difficulties in selling the stocks of small-cap companies at the desired time and price, especially in situations of increased market volatility where a fund may experience high levels of shareholder redemptions. Stocks at the bottom end of the capitalization range of small-cap companies sometimes are referred to as “micro-cap” stocks. These stocks may be subject to extreme price volatility, as well as limited liquidity and limited research. While mid-cap stocks may be slightly less volatile than small-cap stocks, they still involve similar risks.

Valuation risk: 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 readily available market 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 sell a portfolio security at the price established by the pricing

Section 2     How We Manage Your Money

37

service, which could result in a 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. Different 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 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.

Non-Principal Risks

Global economic risk: Global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country, region or market might adversely impact issuers in a different country, region or market. Changes in legal, political, regulatory, tax and economic conditions may cause fluctuations in markets and securities prices around the world, which could negatively impact the value of a fund’s investments. For example, the United Kingdom’s referendum to leave the European Union resulted in the depreciation in value of the British pound, short term declines in the stock markets and ongoing economic and political uncertainty concerning the consequences of the exit. Similar major economic or political disruptions, particularly in large economies like China’s, may have global negative economic and market repercussions. Additionally, geopolitical events, such as war, terrorism, natural and environmental disasters, and market manipulation, may disrupt securities markets and adversely affect global economics and markets. Examples of such events include recent hurricanes in the Caribbean Sea and southern United States and heightened concerns regarding North Korea’s nuclear weapons and long-range ballistic missile programs. Governmental and quasi-governmental authorities and regulators throughout the world have responded to turmoil 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 a fund’s investments.

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 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.

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.

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:

Section 3     How You Can Buy and Sell Shares

39

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 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 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.

Effective July 2018, Class C shares will automatically convert to Class A shares after 10 years, thus reducing future annual expenses. Conversions will occur during the month in which the 10-year anniversary of the purchase occurs. Class C shares that have been held for longer than 10 years as of July 1, 2018 will also convert to Class A shares in July 2018. The automatic conversion will be 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 will 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.

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 R3 Shares

You can purchase Class R3 shares at the offering price, which is the net asset value per share without any up-front sales charge. Class R3 shares are

40

Section 3     How You Can Buy and Sell Shares

subject to annual distribution and service fees of 0.50% of your Fund’s average daily net assets.

Investors may purchase Class R3 shares only for Fund accounts held with a financial advisor or other financial intermediary, and not directly with a Fund.

Class R3 shares are only available for purchase by eligible retirement plans. Class R3 shares are not available to traditional and Roth IRAs, Coverdell Education Savings Accounts, SEPs, SAR-SEPs, SIMPLE IRAs or individual 403(b) plans. See the statement of additional information for more information.

Nuveen Real Asset Income Fund does not issue Class R3 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; 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 million in a Fund. Such 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:

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

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 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:

Class T Shares

You can purchase Class T shares at the offering price, which is the net asset value per share plus an up-front sales charge. Class T shares are also subject to an annual service fee of 0.25% of the Fund’s average daily net assets, which compensates your financial advisor or other financial intermediary for

42

Class T shares purchased through the reinvestment of dividends and capital gain distributions from the same Fund are not subject to a sales charge. In addition, Class T shares may be available at net asset value without a sales charge under certain other circumstances, as determined by the policies and procedures of your financial intermediary. See the appendix to this prospectus, “Variations in Sales Charge Reductions and Waivers Available Through Certain Intermediaries,” for information on available Class T share sales charge waivers.

Investors may purchase Class T shares only for Fund accounts held with a financial advisor or other financial intermediary, and not directly with a Fund. In addition, Class T 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 T shares.

Please refer to the statement of additional information for more information about Class A, Class C, Class R3, Class R6, Class I and Class T 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 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.

Section 3     How You Can Buy and Sell Shares

43

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

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:

44

Section 3     How You Can Buy and Sell Shares

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.

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 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 million, may be waived or reduced under certain circumstances, including the following:

Section 3     How You Can Buy and Sell Shares

45

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.

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, Class C and Class T shares may not be purchased directly from a Fund. In addition, the availability of Class A, Class C and Class T 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, 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

46

Section 3     How You Can Buy and Sell Shares

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.

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

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 Investor Services 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.

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.

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, except that there are no exchange privileges for Class T shares. 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.

48

Section 3     How You Can Buy and Sell Shares

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.

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.

An Important Note About Telephone Transactions

Although Nuveen Investor Services 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.

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

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.

Section 3     How You Can Buy and Sell Shares

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 R3 or 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 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.

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 from a Fund’s net investment income, if any, are normally declared and paid annually for Nuveen Global Infrastructure Fund, declared and paid quarterly for Nuveen Real Estate Securities Fund, and declared daily and paid monthly for Nuveen Real Asset Income Fund. Any capital gains are normally distributed at least once each year. A Fund may, however, pay dividends or make distributions more frequently.

Nuveen Real Asset Income 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 the 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 Fund’s net income over time.

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 Investor Services 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

52

Section 4     General Information

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 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 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 Investor Services 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.

The Tax Cuts and Jobs Act

A large portion of the Funds’ portfolio holdings consist of REITs. For tax years beginning after December 31, 2017, The Tax Cuts and Jobs Act generally would allow a non-corporate taxpayer a deduction of 20% of the investor’s domestic qualified business income received from certain pass-through entities, including REITs. However, Regulated Investment Companies (“ RICs ”) such as the Funds are not explicitly given the ability to pass the deduction through to their non-corporate shareholders. Treasury has been approached to provide RICs the ability to report a portion of their distributions as qualified business income eligible for the 20% deduction. However, until such relief is provided, non-corporate investors will not be able to receive the tax benefit that they would otherwise receive investing directly in the individual REIT securities.

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 and Class R3 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, Class C, Class R3 and Class T 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 and Class R3 shares may pay more in distribution and service fees and CDSCs (Class C shares only) 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

54

Section 4     General Information

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 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.

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

Section 4     General Information

55

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 generally are valued using prices provided by independent pricing services or obtained from other sources, such as broker-dealer quotations. Exchange-traded instruments generally are valued at the last reported sales price or official closing price on an exchange, if available. 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 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.

If a price cannot be obtained from a pricing service or other pre-approved source, or if, in the judgment of Nuveen Fund Advisors, a price is unreliable, a portfolio instrument will be valued at its fair value as determined in good faith by the Board of Directors or its appointee. Nuveen Fund Advisors may determine that a price is 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 has adopted valuation procedures for the Funds and has appointed the Nuveen Fund Advisors’ Valuation Committee with the day-to-day responsibility for fair value determinations. All fair value determinations made by the Valuation Committee are subject to review and ratification by the Board of Directors. 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

56

Section 4     General Information

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.

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 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.

Section 4     General Information

57

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.
