INVESTMENT OBJECTIVE AND STRATEGIES

The following supplements the investment objective, strategies and risks of the Fund as set forth in the Prospectus. The investment objective of the Fund may be changed by the Board of Trustees of the Trust (the “Board”) without shareholder approval. Except as expressly noted below, the Fund’s investment strategies may be changed without shareholder approval. In addition to the instruments discussed below and in the Prospectus, the Fund may purchase other types of financial instruments, however designated, whose investment and credit quality characteristics are determined by Northern Trust Investments, Inc. (“NTI” or the “Investment Adviser,” and collectively with TNTC, “Northern Trust”) to be substantially similar to those of any other investment otherwise permitted by the Fund’s investment strategies.

NAMES RULE POLICIES. The Fund has adopted a policy as stated in its prospectus to invest at least 80% of its net assets in the particular type of investment suggested by its name (“Names Rule Policy”). For these purposes, “net assets” include the amount of any borrowings for investment purposes and the amount of “net assets” is measured at the time of purchase. In addition, in appropriate circumstances, synthetic investments may be included in the 80% basket of the Names Rule Policy if they have economic characteristics similar to the other investments included in the basket.

ARTIFICIAL INTELLIGENCE. The use and development of artificial intelligence (AI) technologies is rapidly increasing and may be used by issuers in which the Fund invests as well as by service providers that provide services to the Fund. AI technologies are highly reliant on the collection and analysis of large amounts of data and complex algorithms, and it is possible that the information generated from AI technologies could be incomplete, inaccurate or biased, which could lead to adverse effects for the issuers or service providers using such technology. Because of these challenges, the use of AI could result in reputational harm, legal liability, adverse effects on business operations and/or operational errors and investment losses, all of which could impact the Fund. In addition, the increasing development and use of AI technologies could impact the market as a whole, including through use by malicious actors for market manipulation, fraud, and cyberattack. Actual usage of AI technologies by the Fund’s service providers and issuers in which the Fund invests will vary. AI technologies and their current and potential future applications, and the regulatory frameworks within which they operate, continue to rapidly evolve, and it is impossible to predict the full extent of future applications or regulations and the associated risks to the Fund.

BORROWINGS. The Fund may engage in borrowing transactions as a means of raising cash to satisfy redemption requests or, to the extent permitted by their investment policies, to raise additional cash to be invested in other securities or instruments in an effort to increase the Fund’s investment returns. Reverse repurchase agreements may be considered to be a type of borrowing.

When the Fund invests borrowing proceeds in other securities, the Fund will be at risk for any fluctuations in the market value of the securities in which the proceeds are invested. Like other leveraging risks, this makes the value of an investment in the Fund more volatile and increases the Fund’s overall investment exposure. In addition, if the Fund’s return on its investment of the borrowing proceeds does not equal or exceed the interest that the Fund is obligated to pay under the terms of a borrowing, engaging in these transactions will lower the Fund’s return.

The Fund may be required to liquidate portfolio securities at a time when it would be disadvantageous to do so in order to make payments with respect to their borrowing obligations. This could adversely affect the Fund’s strategy and result in lower returns. Interest on any borrowings will be a Fund expense and will reduce the value of the Fund’s shares. The Fund may borrow on a secured or on an unsecured basis. If the Fund enters into a secured borrowing arrangement, a portion of the Fund’s assets will be used as collateral. During the term of the borrowing, the Fund will remain at risk for any fluctuations in the market value of these assets in addition to any securities purchased with the proceeds of the loan. In addition, the Fund may be unable to sell the collateral at a time when it would be advantageous to do so, which could adversely affect the Fund’s strategy and result in

4

lower returns. The Fund would also be subject to the risk that the lender may file for bankruptcy, become insolvent, or otherwise default on its obligations to return the collateral to the Fund. In the event of a default by the lender, there may be delays, costs and risks of loss involved in the Fund’s exercising its rights with respect to the collateral or those rights may be limited by other contractual agreements or obligations or by applicable law.

CALCULATION OF PORTFOLIO TURNOVER RATE. The portfolio turnover rate for the Fund is calculated by dividing the lesser of purchases or sales of portfolio investments for the reporting period by the monthly average value of the portfolio investments owned during the reporting period. The calculation excludes all securities, including options, whose maturities or expiration dates at the time of acquisition are one year or less. Portfolio turnover may vary from year to year as well as within a particular year, and may be affected by changes in the holdings of specific issuers, changes in country and currency weightings, cash requirements for redemption of shares and by requirements that enable the Fund to receive favorable tax treatment.

The Fund is not restricted by policy with regard to portfolio turnover and will make changes in their investment portfolios from time to time as business and economic conditions as well as market prices may dictate.

CASH REDEMPTIONS RISK. Paying redemption proceeds entirely in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security or other financial instrument and recognize a capital gain or loss that might not have been incurred if it had not effected a redemption order entirely for cash. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that meet redemption orders entirely in-kind with portfolio securities. The use of all cash creations and redemption orders may also cause the Fund’s shares to trade in the secondary market at wider bid-ask spreads and/or greater premiums or discounts to the Fund’s NAV. To the extent that the maximum additional variable charge for cash creation or cash redemption transactions is insufficient to cover the transaction costs of purchasing or selling portfolio securities, the Fund’s performance could be negatively impacted.

CHANGING INTEREST RATES. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. During periods when interest rates are low (or negative), the Fund’s yield (or total return) may also be low and fall below zero. Very low or negative interest rates may magnify interest rate risk. Changing interest rates may have unpredictable effects on markets, may result in heightened market volatility and increased redemptions, and may detract from the Fund’s performance to the extent the Fund is exposed to such interest rates and/or volatility. A negative interest rate policy is an unconventional central bank monetary policy tool where nominal target interest rates are set with negative value intended to help create self-sustaining growth in the local economy. To the extent the Fund holds a negative-yielding debt instrument or has a bank deposit with a negative interest rate, the Fund would generate a negative return on that investment. Cash positions may also subject the Fund to increased counterparty risk to the Fund’s bank. In a low or negative interest rate environment, investors may seek to reallocate their investment to other income-producing assets. This could cause the price of higher-yielding instruments to rise, could further reduce the value of instruments with a negative yield, and may limit a Fund’s ability to locate fixed income instruments containing the desired risk/return profile.

COMMERCIAL PAPER, BANKERS’ ACCEPTANCES, CERTIFICATES OF DEPOSIT, TIME DEPOSITS AND BANK NOTES. To the extent consistent with its investment objective and strategies, the Fund may invest in commercial paper. Commercial paper represents short-term unsecured promissory notes issued in bearer form by banks or bank holding companies, corporations and finance companies. Certificates of deposit are negotiable certificates issued against funds deposited in a commercial bank for a definite period of time and earning a specified return. Bankers’ acceptances are negotiable drafts or bills of exchange, normally drawn by an importer or exporter to pay for specific merchandise, which are “accepted” by a bank, meaning, in effect, that the bank unconditionally agrees to pay the face value of the instrument on maturity. Fixed time

5

deposits are bank obligations payable at a stated maturity date and bearing interest at a fixed rate. Fixed time deposits may be withdrawn on demand by the investor, but may be subject to early withdrawal penalties that vary depending upon market conditions and the remaining maturity of the obligation. There are no contractual restrictions on the right to transfer a beneficial interest in a fixed time deposit to a third party. Bank notes generally rank junior to deposit liabilities of banks and pari passu with other senior, unsecured obligations of the bank. Bank notes are classified as “other borrowings” on a bank’s balance sheet, while deposit notes and certificates of deposit are classified as deposits. Bank notes are not insured by the FDIC or any other insurer. Deposit notes are insured by the FDIC only to the extent of $250,000 per depositor per bank.

The Fund may invest a portion of its assets in the obligations of foreign banks and foreign branches of domestic banks. Such obligations include Eurodollar Certificates of Deposit, which are U.S. dollar-denominated certificates of deposit issued by offices of foreign and domestic banks located outside the U.S.; Eurodollar Time Deposits (“ETDs”), which are U.S. dollar-denominated deposits in a foreign branch of a U.S. bank or a foreign bank; Canadian Time Deposits, which are essentially the same as ETDs except they are issued by Canadian offices of major Canadian banks; Schedule Bs, which are obligations issued by Canadian branches of foreign or domestic banks; Yankee Certificates of Deposit, which are U.S. dollar-denominated certificates of deposit issued by a U.S. branch of a foreign bank and held in the U.S.; and Yankee Bankers’ Acceptances, which are U.S. dollar-denominated bankers’ acceptances issued by a U.S. branch of a foreign bank and held in the U.S.

Commercial paper is generally unsecured and usually discounted from its value at maturity. The value of commercial paper may be affected by changes in the credit rating or financial condition of the issuing entities and will tend to fall when interest rates rise and rise when interest rates fall. Investments in commercial paper are subject to the risk that the issuer cannot issue enough new commercial paper to satisfy its obligations with respect to its outstanding commercial paper, also known as rollover risk. Commercial paper is also susceptible to changes in the issuer’s financial condition or credit quality. In addition, under certain circumstances commercial paper may become illiquid or may suffer from reduced liquidity. Commercial paper purchased by a Fund may include asset-backed commercial paper. Asset-backed commercial paper is issued by a SPE that is organized to issue the commercial paper and to purchase trade receivables or other financial assets. The credit quality of asset-backed commercial paper depends primarily on the quality of these assets and the level of any additional credit support. The repayment of asset-backed commercial paper depends primarily on the cash collections received from such an issuer’s underlying asset portfolio and the issuer’s ability to issue new asset-backed commercial paper.

Since the Fund may hold investments in non-U.S. bank obligations, an investment in the Fund involves certain additional risks associated with foreign investments, as further described under “Foreign Investments—General.”

CUSTODIAL RECEIPTS FOR TREASURY SECURITIES. To the extent consistent with its investment objective and strategies, the Fund may acquire U.S. government obligations and their unmatured interest coupons that have been separated (“stripped”) by their holder, typically a custodian bank or investment brokerage firm. Having separated the interest coupons from the underlying principal of the U.S. government obligations, the holder will resell the stripped securities in custodial receipt programs with a number of different names, such as TIGRs (Treasury Income Growth Receipts) and CATS (Certificates of Accrual on Treasury Securities). The stripped coupons are sold separately from the underlying principal, which usually is sold at a deep discount because the buyer receives only the right to receive a future fixed payment on the security and does not receive any rights to periodic interest (cash) payments. The underlying U.S. Treasury bonds and notes themselves are held in book-entry form at the Federal Reserve Bank or, in the case of bearer securities (i.e., unregistered securities, which are ostensibly owned by the bearer or holder), in trust on behalf of the owners.

Counsel to the underwriters of these certificates or other evidences of ownership of U.S. Treasury securities have stated that, in their opinion, purchasers of the stripped securities most likely will be deemed the beneficial holders of the underlying U.S. government obligations for federal tax purposes. The Trust is unaware of any

6

binding legislative, judicial or administrative authority on this issue. Custodial receipts may not be considered obligations of the U.S. government or other issuer of the security held by the custodian for purposes of the securities laws. If for tax purposes the Fund is not considered to be the owner of the securities held in the underlying trust or custodial account, the Fund may suffer adverse tax consequences. As a holder of custodial receipts, the Fund will bear its proportionate share of the fees or expenses charged to the custodial account.

CYBERSECURITY RISK. With the increased use of technologies such as mobile devices and Web-based or “cloud” applications, and the dependence on the Internet and computer systems to conduct business, the Fund is susceptible to operational, information security and related risks. In general, cybersecurity incidents can result from deliberate attacks or unintentional events (arising from external or internal sources) that may cause the Fund to lose proprietary information, suffer data corruption, physical damage to a computer or network system or lose operational capacity. Cybersecurity attacks include, but are not limited to, infection by malicious software, such as malware or computer viruses or gaining unauthorized access to digital systems, networks or devices that are used to service the Fund’s operations (e.g., through “hacking,” “phishing” or malicious software coding) or other means for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cybersecurity attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on the Fund’s websites (i.e., efforts to make network services unavailable to intended users). In addition, authorized persons could inadvertently or intentionally release confidential or proprietary information stored on the Fund’s systems. Geopolitical tensions may, from time to time, increase the scale and sophistication of deliberate cyberattacks.

Cybersecurity incidents affecting the Investment Adviser, other service providers (including, but not limited to, the sub-administrator, custodian, sub-custodians, transfer agent and financial intermediaries) or the Fund’s shareholders have the ability to cause disruptions and impact business operations, potentially resulting in financial losses to both the Fund and its shareholders, interference with the Fund’s ability to calculate their net asset values (“NAV”), impediments to trading, the inability of Fund shareholders to transact business and the Fund to process transactions (including fulfillment of Fund share purchases and redemptions), violations of applicable privacy and other laws (including the release of private shareholder information) and attendant breach notification and credit monitoring costs, regulatory fines, penalties, litigation costs, reputational damage, reimbursement or other compensation costs, forensic investigation and remediation costs, and/or additional compliance costs. Similar adverse consequences could result from cybersecurity incidents affecting issuers of securities in which the Fund invests, counterparties with which the Fund engage in transactions, governmental and other regulatory authorities, exchange and other financial market operators, banks, brokers, dealers, insurance companies and other financial institutions (including financial intermediaries and other service providers) and other parties. In addition, substantial costs may be incurred in order to safeguard against and reduce the risk of any cybersecurity incidents in the future. In addition to administrative, technological and procedural safeguards, the Investment Adviser has established business continuity plans in the event of, and risk management systems to prevent or reduce the impact of, such cybersecurity incidents. However, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified, as well as the rapid development of new threats. Furthermore, the Fund and the Investment Adviser have limited ability to prevent or mitigate cybersecurity incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Investment Adviser, and the Fund cannot control the cybersecurity plans and systems put in place by its service providers or any other third parties whose operations may affect the Fund or its shareholders. The Fund and its shareholders could be negatively impacted as a result.

DEMAND FEATURES AND GUARANTEES. To the extent consistent with its investment objective and strategies, the Fund may invest in securities that have demand features, guarantees or similar credit and liquidity enhancements. A demand feature permits the holder of the security to sell the security within a specified period of time at a stated exercise price and entitles the holder of the security to receive an amount equal to the approximate amortized cost of the security plus accrued interest. A guarantee permits the holder of the security to receive, upon presentment to the guarantor, the principal amount of the underlying security plus accrued interest

7

when due or upon default. A guarantee is the unconditional obligation of an entity other than the issuer of the security. Demand features and guarantees can effectively:

The aggregate price for a security subject to a demand feature or a guarantee may be higher than the price that would otherwise be paid for the security without the guarantee or the demand feature. When the Fund purchases securities subject to guarantees or demand features, there is an increase in the cost of the underlying security and a corresponding reduction in its yield. Securities with demand features may involve certain expenses and risks, including the inability of the issuer of the security to pay for the underlying securities at the time the demand is exercised, non-marketability of the security and differences between the maturity of the underlying security and the maturity of the demand security. Because the Fund invests in securities backed by banks and other financial institutions, changes in the credit quality of these institutions could cause losses to the Fund.

DEPOSITARY RECEIPTS. Depositary receipts demonstrate ownership of shares of a foreign issuer and are alternatives to directly purchasing the underlying foreign security. Depositary receipts may be sponsored or unsponsored and include American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”), European Depositary Receipts (“EDRs”) and non-voting depositary receipts (“NVDRs”). To the extent consistent with its investment objective and strategies, the Fund may invest in ADRs, EDRs, GDRs and/or NVDRs.

ADRs in registered form are typically issued by a U.S. bank or trust company, traded in U.S. dollars, and are designed for use in the domestic market. GDRs, EDRs, NVDRs and other similar instruments may be issued by a U.S. or non-U.S. entity and may be traded in other currencies. GDRs are tradable both in the U.S. and Europe and are designed for use throughout the world. EDRs are issued in bearer form and are designed for use in European securities markets.

Depositary receipts in general are subject to many of the risks associated with foreign investing (e.g., increased market, illiquidity, currency, political, information and other risks), and even where traded in U.S. dollars are subject to currency risk if the underlying security is traded in a foreign currency. Unsponsored depositary receipts are issued without the participation of the issuer of the underlying foreign security and there may be less information available about such issuers than there is with respect to domestic companies and issuers of securities underlying sponsored depositary receipts. Even if there is information available, there may not be a correlation between such information and the market value of the depositary receipts.

EQUITY-LINKED NOTES. An equity-linked note (“ELN”) is a debt instrument whose value is based on the value of a single equity security, basket of equity securities or an index of equity securities (each, an “Underlying Equity”). An ELN typically provides interest income, thereby offering a yield advantage over investing directly in an Underlying Equity. To the extent consistent with its investment objective and strategies, the Fund may purchase ELNs that trade on a securities exchange or those that trade on the over-the-counter markets, including Rule 144A securities. The Fund may also purchase ELNs in a privately negotiated transaction with the issuer of the ELNs (or its broker-dealer affiliate). The Fund may or may not hold an ELN until its maturity.

Equity-linked securities also include issues such as Structured Yield Product Exchangeable for Stock (“STRYPES”), Trust Automatic Common Exchange Securities (“TRACES”), Trust Issued Mandatory Exchange Securities (“TIMES”) and Trust Enhanced Dividend Securities (“TRENDS”). The issuers of these equity-linked securities generally purchase and hold a portion of stripped U.S. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on such equity-linked securities generally consist of the cash received from the U.S. Treasury securities and such equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

8

ELNs also include participation notes issued by a bank or broker-dealer that entitles the Fund to a return measured by the change in value of an Underlying Equity. Participation notes are typically used when a direct investment in the Underlying Equity is restricted due to country-specific regulations. Investment in a participation note is the same as investment in the constituent shares of the company (or other issuer type) to which the Underlying Equity is economically tied. A participation note represents only an obligation of the company or other issuer type to provide the Fund the economic performance equivalent to holding shares of the Underlying Equity. A participation note does not provide any beneficial or equitable entitlement or interest in the relevant Underlying Equity. In other words, shares of the Underlying Equity are not in any way owned by the Fund.

EQUITY SECURITIES. To the extent consistent with its investment objective and strategies, the Fund may invest in equity securities. “Equity securities” include common stocks, preferred stocks, investment companies including ETFs, interests in real estate investment trusts (“REITs”), convertible securities, equity interests in trusts, partnerships, joint ventures, limited liability companies and similar enterprises, warrants, stock purchase rights and synthetic and derivative instruments that have economic characteristics similar to equity securities.

Investing in equity securities involves market risk. Market risk is the risk that the value of a Fund’s investments may increase or decrease in response to expected, real or perceived economic, political or financial events in the U.S. or global markets. The frequency and magnitude of such changes in value cannot be predicted. Certain securities and other investments held by the Fund may experience increased volatility, illiquidity, or other potentially adverse effects in response to changing market conditions, inflation, changes in interest rates, lack of liquidity in the bond or equity markets, volatility in the equity markets, market disruptions caused by local or regional events such as war, acts of terrorism, the spread of infectious illness (including epidemics and pandemics) or other public health issues, recessions or other events or adverse investor sentiment or other political, regulatory, economic and social developments, and developments that impact specific economic sectors, industries or segments of the market. During periods of market disruption or other abnormal market conditions, the Fund’s exposure to risks described elsewhere in its prospectus and this SAI will likely increase.

Over the past several years, stock markets have experienced substantial price volatility. Growth stocks are generally more sensitive to market movements than other types of stocks and their stock prices may therefore be more volatile and present a higher degree of risk of loss. Value stocks, on the other hand, may fall out of favor with investors and underperform growth stocks during any given period. Stock prices may fluctuate from time to time in response to the activities of individual companies and in response to general market and economic conditions. Individual companies may report poor results or be negatively affected by industry trends and developments, and the stock prices of such companies may decline in response.

The U.S. government and the Federal Reserve, as well as certain foreign governments and central banks, have taken extraordinary actions to support local and global economies and the financial markets in response to the COVID-19 pandemic. These events and the possible resulting market volatility from the residual effects of the COVID-19 pandemic may have an adverse effect on the Fund.

EQUITY SWAPS. To the extent consistent with its investment objective and strategies, the Fund, may enter into equity swap contracts to invest in a market without owning or taking physical custody of securities in circumstances in which direct investment is restricted for legal reasons or is otherwise impracticable. Equity swaps may be used by the Fund to the extent consistent with its investment objective and strategies for hedging purposes, to seek to increase total return, or for liquidity management purposes. The counterparty to an equity swap contract will typically be a bank, investment banking firm or broker/dealer. Equity swap contracts may be structured in different ways. For example, a counterparty may agree to pay the Fund the amount, if any, by which the notional amount of the equity swap contract would have increased in value had it been invested in particular stocks (or an index of stocks), plus the dividends that would have been received on those stocks. In these cases, the Fund may agree to pay to the counterparty the amount, if any, by which that notional amount would have

9

decreased in value had it been invested in the stocks. Therefore, the return to the Fund on any equity swap contract should be the gain or loss on the notional amount plus dividends on the stocks less the interest paid by the Fund on the notional amount. In other cases, the counterparty and the Fund may each agree to pay the other the difference between the relative investment performances that would have been achieved if the notional amount of the equity swap contract had been invested in different stocks (or indices of stocks).

The Fund will enter into equity swaps only on a net basis, which means that the two payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. Payments may be made at the conclusion of an equity swap contract or periodically during its term. Equity swaps do not involve the delivery of securities or other underlying assets. Accordingly, the risk of loss with respect to equity swaps is limited to the net amount of payments that the Fund is contractually obligated to make. If the other party to an equity swap defaults, the Fund’s risk of loss consists of the net amount of payments that the Fund is contractually entitled to receive, if any.

The Fund will not enter into any swap transactions unless the unsecured commercial paper, senior debt or claims-paying ability of the other party is rated either A, or A-1 or better by S&P or Fitch; or A or Prime-1 or better by Moody’s, or has received a comparable rating from another organization that is recognized as a NRSRO. If there is a default by the other party to such a transaction, the Fund will have contractual remedies pursuant to the agreements related to the transaction.

The use of equity swaps is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Investment Adviser or a Sub-Adviser is incorrect in its forecasts of market values, the investment performance of the Fund would be less favorable than it would have been if this investment technique were not used. For a description of CFTC regulations affecting swap transactions and certain other derivatives, see “Futures Contracts and Related Options.”

EXCHANGE RATE-RELATED SECURITIES. To the extent consistent with its investment objective and strategies, the Fund may invest in exchange rate-related securities. Exchange rate-related securities represent certain foreign debt obligations whose principal values are linked to a foreign currency but which are repaid in U.S. dollars. The principal payable on an exchange rate-related security is subject to currency risk. In addition, the potential illiquidity and high volatility of the foreign exchange market may make exchange rate-related securities difficult to sell prior to maturity at an appropriate price.

EXCHANGE-TRADED NOTES. To the extent consistent with its investment objective and strategies, the Fund may invest in Exchange-Traded Notes (“ETNs”). ETNs are a type of debt security that trades on exchanges and promises a return linked to a market index or other benchmark. ETNs are unsecured debt obligations of the issuer—typically a bank or another financial institution. They differ from traditional bonds in certain ways. For example, unlike traditional bonds, ETNs typically do not pay any interest payments to investors. Instead, the issuer promises to pay the holder of the ETN an amount determined by the performance of the underlying index or benchmark on the ETN’s maturity date (typically 10, 30 or in some cases even 40 years from issuance), minus any specified fees. The performance of an ETN over long periods can differ significantly from the performance of the underlying index or benchmark. Some ETNs are callable at the issuer’s discretion. In addition, unlike traditional bonds, ETNs trade on exchanges throughout the day at prices determined by the market, similar to stocks or ETFs. But unlike index-based ETFs, ETNs do not buy or hold assets to replicate or approximate the performance of the underlying index. The secondary market price of an ETN may differ significantly from its indicative value as calculated by the issuer.

The issuer of an ETN may engage in trading activity that is at odds with the interests of investors who hold the ETNs.

ETNs carry various risks, including default risk, credit risk, market risk and liquidity risk. The absence of an active secondary market for ETNs could make it difficult to dispose of the ETNs.

10

FOREIGN CURRENCY TRANSACTIONS. To the extent consistent with its investment objective and strategies, the Fund may enter into forward foreign currency exchange contracts in order to protect against a possible loss on investments resulting from a decline or appreciation in the value of a particular foreign currency against the U.S. dollar or another foreign currency or for other reasons, the Fund is authorized to enter into forward foreign currency exchange contracts. These contracts involve an obligation to purchase or sell a specified currency at a future date at a price set at the time of the contract. Forward foreign currency exchange contracts do not eliminate fluctuations in the values of portfolio securities but rather allow the Fund to establish a rate of exchange for a future point in time.

When entering into a contract for the purchase or sale of a security, the Fund may enter into a forward foreign currency exchange contract for the amount of the purchase or sale price to protect against variations, between the date the security is purchased or sold and the date on which payment is made or received, in the value of the foreign currency relative to the U.S. dollar or other foreign currency.

When the Investment Adviser anticipates that a particular foreign currency may decline relative to the U.S. dollar or other leading currencies, in order to reduce risk, the Fund may enter into a forward contract to sell, for a fixed amount, the amount of foreign currency approximating the value of some or all of the Fund’s securities denominated in such foreign currency. Similarly, when the securities held by the Fund create a short position in a foreign currency, the Fund may enter into a forward contract to buy, for a fixed amount, an amount of foreign currency approximating the short position. With respect to any forward foreign currency exchange contract, it generally will not be possible to match precisely the amount covered by that contract and the value of the securities involved due to the changes in the values of such securities resulting from market movements between the date the forward contract is entered into and the date it matures. In addition, while forward contracts may offer protection from losses resulting from declines or appreciation in the value of a particular foreign currency, they also limit potential gains, which might result from changes in the value of such currency. The Fund also may incur costs in connection with forward foreign currency exchange contracts and conversions of foreign currencies and U.S. dollars.

In addition, to the extent consistent with its investment objective and strategies, the Fund may purchase or sell forward foreign currency exchange contracts to seek to increase total return or for cross-hedging purposes and may engage in cross-hedging by using forward contracts in one currency to hedge against fluctuations in the value of securities denominated in a different currency if the investment management team believes that there is a pattern of correlation between the two currencies. Additionally, to the extent consistent with its investment objective and strategies, the Fund may also purchase or sell forward foreign currency exchange contracts to gain exposure to certain currencies.

FOREIGN INVESTMENTS—GENERAL. To the extent consistent with its investment objective and strategies, the Fund may invest in foreign securities, including bonds and other fixed income securities of foreign issuers. Foreign fixed-income securities may include eurodollar convertible securities, which are fixed-income securities that are issued in U.S. dollars outside the U.S. and are convertible into or exchangeable for equity securities of the same or a different issuer.

To the extent consistent with its investment objective and strategies, the Fund also may invest in U.S. dollar-denominated obligations issued or guaranteed by one or more foreign governments or any of their political subdivisions, agencies, instrumentalities or sponsored enterprises, as well as other foreign issuers. These obligations may be issued by supranational entities, including international organizations (such as the International Bank for Reconstruction and Development (also known as the World Bank)) designed or supported by governmental entities to promote economic reconstruction or development and international banking institutions and related government agencies.

Investment in foreign securities involves special risks. These include market risk, interest rate risk, market trading risk and currency risk. Market risk involves the possibility that security prices will decline over short or even extended periods. The markets tend to be cyclical, with periods of generally rising prices and periods of

11

generally declining prices. These cycles will affect the value of the Fund to the extent that it invests in foreign securities. The holdings of the Fund, to the extent that it invests in fixed-income securities, will be sensitive to changes in interest rates and the interest rate environment. Generally, the prices of bonds and debt securities fluctuate inversely with interest rate changes. In addition, the performance of investments in securities denominated in a foreign currency will depend on the strength of the foreign currency against the U.S. dollar and the interest rate environment in the country issuing the currency. Absent other events that could otherwise affect the value of a foreign security (such as a change in the political climate or an issuer’s credit quality), appreciation in the value of the foreign currency generally can be expected to increase the value of a foreign currency-denominated security in terms of U.S. dollars. A rise in foreign interest rates or decline in the value of the foreign currency relative to the U.S. dollar generally can be expected to depress the value of a foreign currency-denominated security. Generally, the prices of bonds and debt securities fluctuate inversely with interest rate changes.

There are other risks and costs involved in investing in foreign securities, which are in addition to the usual risks inherent in domestic investments. Investment in foreign securities involves higher costs than investment in U.S. securities, including higher transaction and custody costs as well as the imposition of additional taxes by foreign governments. Foreign investments also involve risks associated with the level of currency exchange rates, less complete financial information about the issuers, less market liquidity, more market volatility and political instability. Future political, financial, social and economic developments in foreign countries (including, for example, military confrontations, war and terrorism), the possible imposition of withholding taxes on dividend income, the possible seizure or nationalization of foreign holdings, the possible establishment of exchange controls, or freezes on the convertibility of currency, trade restrictions (including tariffs) or the adoption of other governmental restrictions might adversely affect an investment in foreign securities. Additionally, foreign banks and foreign branches of domestic banks are subject to less stringent reserve requirements, and to different accounting, auditing and recordkeeping requirements. Also, the legal remedies for investors may be more limited than the remedies available in the U.S. Additionally, many countries throughout the world are dependent on a healthy U.S. economy and are adversely affected when the U.S. economy weakens or its markets decline. For example, the decline in the U.S. subprime mortgage market quickly spread throughout global credit markets, triggering a liquidity crisis that affected fixed-income and equity markets around the world.

The energy, materials and agriculture sectors may account for a large portion of a foreign country’s exports. Any changes in these sectors or fluctuations in the commodity markets could have an adverse impact on a country’s economy. Commodity prices may be influenced or characterized by unpredictable factors, including where applicable, high volatility, changes in supply and demand relationships, weather, agriculture, trade, pestilence, changes in interest rates and monetary and other governmental policies, action and inaction. Securities of companies held by the Fund that are dependent on a single commodity, or are concentrated in a single commodity sector, may typically exhibit even higher volatility attributable to commodity prices.

European countries can be affected by the significant fiscal and monetary controls that the European Economic and Monetary Union (“EMU”) imposes for membership. Europe’s economies are diverse, its governments are decentralized, and its cultures vary widely. Several European Union (“EU”) countries, including Greece, Ireland, Italy, Spain and Portugal, have faced budget issues, some of which may have negative long-term effects for the economies of those countries and other EU countries. There is continued concern about national-level support for the euro and the accompanying coordination of fiscal and wage policy among EMU member countries. Member countries are required to maintain tight control over inflation, public debt, and budget deficit to qualify for membership in the EMU. These requirements can severely limit the ability of EMU member countries to implement monetary policy to address regional economic conditions.

In June of 2016, the United Kingdom (the “UK”) approved a referendum to leave the EU, commonly referred to as “Brexit,” which sparked depreciation in the value of the British pound and heightened risk of continued worldwide economic volatility. Pursuant to Article 50 of the Treaty of Lisbon, the UK gave notice in March 2017 of its withdrawal from the EU and commenced negotiations on the terms of withdrawal. Following

12

years of negotiation and multiple deadline extensions, the UK withdrew from the EU on January 31, 2020. On May 1, 2021 the UK and EU entered into the EU-UK Trade and Cooperation Agreement, which governs certain aspects of their relationship.

The effects of this withdrawal will depend, in part, on trade and finance agreements the UK negotiates to retain access to EU markets. The UK’s exit from the EU may cause significant market volatility and illiquidity, currency fluctuations, deterioration in economic activity, legal uncertainty, a decrease in business confidence, and increased likelihood of a recession in the UK. This may increase redemptions from a Fund that holds impacted securities or cause the value of the Fund’s securities that are economically tied to the UK or EU to decline. Market factors, such as the demand for particular portfolio securities, may cause the price of certain portfolio securities to fall while the price of other securities rise or remain unchanged. There is significant uncertainty regarding Brexit’s ramifications and the range and potential implications of possible political, regulatory, economic and market outcomes are difficult to predict. Securities issued by companies domiciled in the UK could be subject to changing regulatory and tax regimes. Banking and financial services companies that operate in the UK or EU could be disproportionately impacted by those actions. Other countries may seek to withdraw from the EU and/or abandon the euro, the common currency of the EU, which could exacerbate market and currency volatility and negatively impact the Fund’s investments in securities issued by companies located in EU countries. Other economic challenges facing Europe include high levels of public debt, significant rates of unemployment, aging populations, mass migrations from the Middle East and Africa and heavy regulation in certain economic sectors. European governments have taken unprecedented steps to respond to the economic crises and to boost growth in the region, which has increased the risk that regulatory uncertainty could negatively affect the Fund’s investments. Ukraine has experienced an ongoing military conflict, most recently in February 2022 when Russia invaded Ukraine; this conflict may expand and military attacks could occur throughout Europe. Additionally, in October 2023 armed conflict broke out between Israel and the militant group Hamas after Hamas infiltrated Israel’s southern border from the Gaza Strip. Israel has since declared war against Hamas and this conflict has escalated into a greater regional conflict. The ultimate effects of these events and other socio-political or geopolitical issues are not known but could profoundly affect global economies and markets. The impact of these actions, especially if they occur in a disorderly fashion, is not clear but could be significant and far-reaching.

Many non-governmental issuers, and even certain governments, have defaulted on, or been forced to restructure, their debts; many other issuers have faced difficulties obtaining credit or refinancing existing obligations; financial institutions have in many cases required government or central bank support, have needed to raise capital, and/or have been impaired in their ability to extend credit; and financial markets in Europe and elsewhere have experienced extreme volatility and declines in asset values and liquidity. These difficulties may continue, worsen or spread within and without Europe. Responses to the financial problems by European governments, central banks and others, including austerity measures and reforms, may not work, may result in social unrest and may limit future growth and economic recovery or have other unintended consequences. Further defaults or restructurings by governments and others of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world.

To the extent consistent with its investment objective and strategies, the Fund may invest in foreign debt, including the securities of foreign governments, in both developed and emerging markets. Several risks exist concerning such investments, including the risk that foreign governments may default on their obligations, may not respect the integrity of such debt, may attempt to renegotiate the debt at a lower rate, and may not honor investments by U.S. entities or citizens.

Although the Fund may invest in securities denominated in foreign currencies, its portfolio securities and other assets are valued in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time causing, together with other factors, the Fund’s NAV to fluctuate as well. Currency exchange rates can be affected unpredictably by the intervention or the failure to intervene by U.S. or foreign governments or central banks, or by currency controls or political developments in the U.S. or abroad. To the extent that the Fund’s total

13

assets, adjusted to reflect the Fund’s net position after giving effect to currency transactions, are denominated in the currencies of foreign countries, the Fund will be more susceptible to the risk of adverse economic and political developments within those countries.

Dividends and interest payable on the Fund’s foreign portfolio securities may be subject to foreign withholding taxes. To the extent such taxes are not offset by credits or deductions allowed to investors under U.S. federal income tax law, they may reduce the net return to the shareholders. See “Taxes.”

The Fund’s income and, in some cases, capital gains from foreign stocks and securities will be subject to applicable taxation in certain of the countries in which they invest, and treaties between the U.S. and such countries may not be available in some cases to reduce the otherwise applicable tax rates. See “Taxes.”

The Fund also is subject to the possible imposition of exchange control regulations or freezes on the convertibility of currency. In addition, through the use of forward currency exchange contracts with other instruments, the net currency positions of a Fund may expose the Fund to risks independent of its securities positions. Although the net long and short foreign currency exposure of the Fund will not exceed its total asset values, to the extent that the Fund is fully invested in foreign securities while also maintaining currency positions, it may be exposed to greater risk than it would have if it did not maintain the currency positions.

Investors should understand that the expense ratios of a Fund that invest primarily in foreign securities can be expected to be higher than those funds investing primarily in domestic securities. The costs attributable to investing abroad usually are higher for several reasons, such as the higher cost of investment research, higher costs of custody of foreign securities, higher commissions paid on comparable transactions on foreign markets and additional costs arising from delays in settlements of transactions involving foreign securities.

Foreign securities are generally held outside the U.S. in the primary market for the securities in the custody of certain eligible foreign banks and trust companies appointed by the Fund’s custodian, as permitted under the 1940 Act (“foreign sub-custodians”). Settlement practices for foreign securities may differ from those in the U.S. Some foreign sub-custodians may be recently organized or new to the foreign custody business. Some countries have limited governmental oversight and regulation of industry practices, stock exchanges, depositories, registrars, brokers and listed companies, which increases the risk of corruption and fraud and the possibility of losses to the Fund. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a foreign sub-custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

Under certain circumstances, foreign securities may settle on a delayed delivery basis, meaning that the Fund may be required to make payment for securities before the Fund has actually received delivery of the securities or deliver securities prior to the receipt of payment. Typically, in these cases, the Fund will receive evidence of ownership in accordance with the generally accepted settlement practices in the local market entitling the Fund to deliver payment at a future date, but there is a risk that the security will not be delivered to the Fund or that payment will not be received, although the Fund and its foreign sub-custodians take reasonable precautions to mitigate this risk.

Foreign markets also have different clearance and settlement procedures, and in certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such transactions. Such delays in settlement could result in temporary periods when a portion of the assets of the Fund remains uninvested and no return is earned on such assets. The inability of the Fund to make intended security purchases or sales due to settlement problems could result in missed attractive investment opportunities, losses to the Fund due to subsequent declines in value of the portfolio securities or, if the Fund has entered into a contract to sell the securities, possible liability to the purchaser. Losses can also result from lost,

14

stolen or counterfeit securities; defaults by brokers and banks; failures or defects of the settlement system; or poor and improper record keeping by registrars and issuers.

Share blocking refers to a practice in certain foreign markets under which an issuer’s securities are blocked from trading at the custodian or sub-custodian level for a specified number of days before and, in certain instances, after a shareholder meeting where a vote of shareholders takes place. The blocking period can last up to several weeks. Share blocking may prevent the Fund from buying or selling securities during this period, because during the time shares are blocked, trades in such securities will not settle. It may be difficult or impossible to lift blocking restrictions, with the particular requirements varying widely by country.

FOREIGN INVESTMENTS—EMERGING AND FRONTIER MARKETS. To the extent consistent with its investment objective and strategies, the Fund may invest in issuers based in or economically tied to emerging and frontier markets countries. Emerging and frontier market countries are generally located in the Asia and Pacific regions, the Middle East, Eastern Europe, Central America, South America and Africa. Political and economic structures in many of these countries may be undergoing significant evolution and rapid development, and these countries may lack the social, political and economic stability characteristics of more developed countries.

In general, the securities markets of emerging and frontier countries are less liquid, subject to greater price volatility, and have a smaller market capitalization than the U.S. securities markets. In certain countries, there may be fewer publicly traded securities and the market may be dominated by a few issues or sectors. Issuers and securities markets in such countries are not subject to as extensive and frequent accounting, financial and other reporting requirements or as comprehensive government regulations as are issuers and securities markets in the U.S. In particular, the assets and profits appearing on the financial statements of emerging and frontier country issuers may not reflect their financial position or results of operations in the same manner as financial statements for U.S. issuers. Substantially less information may be publicly available about emerging and frontier country issuers than is available about issuers in the U.S. The local taxation of income and capital gains accruing to non-residents varies among emerging market countries and may be comparatively high. Emerging market countries typically have less well-defined tax laws and procedures and such laws may permit retroactive taxation so that the Fund could in the future become subject to local tax liabilities that had not been anticipated in valuing its assets or making investments.

Emerging and frontier country securities markets are typically marked by a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of ownership of such securities by a limited number of investors. The markets for securities in certain emerging and frontier countries are in the earliest stages of their development. Even the markets for relatively widely traded securities in emerging and frontier countries may not be able to absorb, without price disruptions, a significant increase in trading volume or trades of a size customarily undertaken by institutional investors in the securities markets of developed countries. The limited size of many of these securities markets can cause prices to be erratic for reasons apart from factors that affect the soundness and competitiveness of the securities issuers. For example, prices may be unduly influenced by traders who control large positions in these markets. Additionally, market making and arbitrage activities are generally less extensive in such markets, which may contribute to increased volatility and reduced liquidity of such markets. The limited liquidity of emerging and frontier country securities may also affect the Fund’s ability to accurately value its portfolio securities or to acquire or dispose of securities at the price and time it wishes to do so or in order to meet redemption requests.

Certain emerging and frontier market countries may have antiquated legal systems, which may adversely impact the Fund. For example, while the potential liability of a shareholder in a U.S. corporation with respect to acts of the corporation is generally limited to the amount of the shareholder’s investment, the notion of limited liability is less clear in certain emerging and frontier market countries. Similarly, the rights of investors in emerging and frontier market companies may be more limited than those of shareholders in U.S. corporations. In

15

addition, the systems of corporate governance to which issuers in certain emerging and frontier countries are subject may be less advanced than the systems to which issuers located in more developed countries are subject, and therefore, shareholders of such issuers may not receive many of the protections available to shareholders of issuers located in more developed countries.

Transaction costs, including brokerage commissions or dealer mark-ups, in emerging and frontier countries may be higher than in developed securities markets. In addition, existing laws and regulations are often inconsistently applied. As legal systems in emerging and frontier countries develop, foreign investors may be adversely affected by new or amended laws and regulations. In circumstances where adequate laws exist, it may not be possible to obtain swift and equitable enforcement of the law.

Certain emerging and frontier countries may restrict or control foreign investments in their securities markets. These restrictions may limit the Fund’s investment in those countries and may increase the expenses of the Fund. Certain emerging and frontier countries require governmental approval prior to investments by foreign persons or limit investment by foreign persons to only a specified percentage of an issuer’s outstanding securities or a specific class of securities, which may have less advantageous terms (including price) than securities of the company available for purchase by nationals. In addition, the repatriation of both investment income and capital from emerging and frontier countries may be subject to restrictions that require governmental consents or prohibit repatriation entirely for a period of time. Even where there is no outright restriction on repatriation of capital, the mechanics of repatriation may affect certain aspects of the operation of the Fund.

Emerging and frontier countries may be subject to a substantially greater degree of economic, political and social instability and disruption than more developed countries. This instability may result from, among other things, the following: (i) authoritarian governments or military involvement in political and economic decision making, including changes or attempted changes in governments through extra-constitutional means; (ii) social unrest associated with demands for improved political, economic or social conditions; (iii) internal insurgencies; (iv) hostile relations with neighboring countries; (v) ethnic, religious and racial disaffection or conflict; and (vi) the absence of developed legal structures governing foreign private investments and private property. Such economic, political and social instability could disrupt the principal financial markets in which the Fund may invest and adversely affect the value of the Fund’s assets. The Fund’s investments can also be adversely affected by any increase in taxes or by political, economic or diplomatic developments.

The economies of emerging and frontier countries may suffer from unfavorable growth of gross domestic product, rates of inflation and hyperinflation, capital reinvestment, resources, self-sufficiency and balance of payments. Many emerging and frontier countries have experienced in the past, and continue to experience, high rates of inflation. In certain countries inflation has at times accelerated rapidly to hyperinflationary levels, creating a negative interest rate environment and sharply eroding the value of outstanding financial assets in those countries. Other emerging and frontier countries, on the other hand, have recently experienced deflationary pressures and are in economic recessions. The economies of many emerging and frontier countries are heavily dependent upon international trade and are accordingly affected by protective trade barriers and the economic conditions of their trading partners. In addition, the economies of some emerging and frontier countries are vulnerable to weakness in world prices for their commodity exports.

Risks related to currencies and corporate actions are also greater in emerging and frontier countries than in developed countries. For example, some emerging and frontier countries may have fixed or managed currencies that are not free-floating against the U.S. dollar. Certain emerging and frontier countries may experience sudden and large adjustments in their currency, which can have a disruptive and adverse effect on foreign investors. Some emerging and frontier countries have a higher risk of currency devaluations, and some of these countries may experience sustained periods of high inflation or rapid changes in inflation rates, which can have negative effects on a country’s economy and securities markets. There may be no significant foreign exchange market for certain currencies making it difficult for the Fund to engage in foreign currency transactions designed to protect the value of the Fund’s investments denominated in such currencies. Some emerging and frontier countries may

16

impose restrictions on the free conversion of their currencies into foreign currencies, including the U.S. dollar. Corporate action procedures in emerging and frontier countries may be less reliable and have limited or no involvement by the depositories and central banks. Lack of standard practices and payment systems can lead to significant delays in payment.

Many emerging and frontier countries are highly dependent on foreign loans for their operations. There have been moratoria on, and refinancing of, repayments with respect to these loans. Some of the refinancings have imposed restrictions and conditions on the economies of such nations that have adversely affected their economic growth.

Frontier countries generally have smaller economies or less developed capital markets than traditional emerging markets and, as a result, the risks of investing in emerging market countries are magnified in frontier countries.

Investment exposure to China subjects the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is a developing market and demonstrates significantly higher volatility from time to time in comparison to developed markets. The Chinese government has undertaken reform of economic and market practices and expansion of the sphere for private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Military conflicts, either in response to internal social unrest or conflicts with other countries, could disrupt economic development. Since 1997, there have been tensions between the Chinese government and many people in Hong Kong who perceive China as tightening control over Hong Kong’s semi-autonomous liberal political, economic, legal, and social framework. Recent protests and unrest have increased tensions even further. Due to the interconnected nature of the Hong Kong and Chinese economies, this instability in Hong Kong may cause uncertainty in the Hong Kong and Chinese markets. China has a complex territorial dispute regarding the sovereignty of Taiwan and has made threats of invasion. Taiwan-based companies and individuals are significant investors in China. Military conflict between China and Taiwan may adversely affect securities of Chinese issuers. The Chinese economy is export-driven and highly reliant on trade. Adverse changes to the economic conditions of its primary trading partners, such as the U.S., Japan and South Korea, would adversely impact the Chinese economy. Reduction in spending on Chinese products and services or the institution of tariffs or other trade barriers by China’s key trading partners may also have an adverse impact on the Chinese economy.

In addition, there is less regulation and monitoring of the securities markets and the activities of investors, brokers and other participants in China than in the U.S. Accordingly, issuers of securities in China are not subject to the same degree of regulation as those in the U.S. with respect to such matters as insider trading rules, tender offer regulation, stockholder proxy requirements and the requirements mandating timely and accurate disclosure of information. Stock markets in China are in the process of change and further development. This may lead to trading volatility, and difficulties in the settlement and recording of transactions and interpretation and application of the relevant regulations. Custodians may not be able to offer the level of service and safe-keeping in relation to the settlement and administration of securities in China that is customary in more developed markets. In particular, there is a risk that the Fund may not be recognized as the owner of securities that are held on behalf of the Fund.

The Public Company Accounting Oversight Board (“PCAOB”) also has historically had difficulties in inspecting audit work papers and practices of PCAOB-registered accounting firms in China with respect to their audit work of U.S. reporting companies. Such issues with respect to the PCAOB inspections may impose significant additional risks associated with investments in China, including the risks that the audits may be less reliable, the information about the Chinese securities may be less reliable or complete, or a U.S.-listed Chinese issuer may be delisted if the PCAOB is unable to inspect the accounting firm for the issuer.

17

Political tension between the U.S. and China has escalated due to a series of trade, international treaty, tax, and sanctions actions between the two countries, including the imposition of tariffs and sanctions, detention of certain products, enhancement of extensive export controls on the semiconductor industry, and countersanctions or countermeasures from the Chinese government that have been triggered or are expected to be triggered. The current political climate and recent worsening trade relations between the U.S. and China have intensified concerns about a potential trade war between the two countries, as each country has recently imposed heavy tariffs on the other country’s products. These actions, an even further increase in tariffs and other potential restrictions on trade between the two countries, and further worsening trade relations more generally, may trigger market volatility, a significant reduction in international trade, the oversupply of certain manufactured goods, substantial price reductions of goods and possible failure of individual companies and/or large segments of China’s export industry, which could have a negative impact on the Fund’s performance. Events such as these and their consequences are difficult to predict and it is unclear whether further tariffs may be imposed or other escalating actions may be taken in the future.

As of the date of this SAI, China, including Hong Kong, is designated as a “foreign adversary” of the United States under U.S. regulations, a designation that subjects certain transactions involving information and communications technology to heightened scrutiny and the potential that such transactions may be prohibited.

In addition, actions by the U.S. government, such as delisting of certain Chinese companies from U.S. securities exchanges or otherwise restricting their operations in the United States, may negatively impact the value and liquidity of such securities held by the Fund. Further, from time to time, certain companies in which the Fund invests may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or in countries the U.S. government identified as state sponsors of terrorism. One or more of these companies may be subject to constraints under U.S. law or regulations that could negatively affect the company’s performance.

The Shanghai-Hong Kong Stock Connect program and the Shenzhen-Hong Kong Stock Connect program (both programs collectively referred to as the Stock Connect Program) are securities trading and clearing programs through which the Fund can trade eligible listed China A-shares. The Stock Connect Program is subject to quota limitations, which may restrict or preclude the Fund’s ability to invest in Stock Connect securities. Foreign investors, individually and in the aggregate, are subject to ownership limitations from Shanghai- or Shenzhen-listed companies, including those purchased through the Stock Connect Program. Once the daily quota is reached orders to purchase additional China A-shares through the Stock Connect Program will be rejected. Only certain China A-shares are eligible to be accessed through the Stock Connect Program. Such securities may lose their eligibility at any time, in which case they could be sold but could no longer be purchased through the Stock Connect Program. The Stock Connect Program is subject to regulations promulgated by regulatory authorities for the Shanghai Stock Exchange, the Stock Exchange of Hong Kong Limited, and the Shenzhen Stock Exchange, and further regulations or restrictions, such as limitations on redemptions or suspension of trading, may adversely impact the Stock Connect Program, if the authorities believe it necessary to assure orderly markets or for other reasons. There is no guarantee that all three exchanges will continue to support the Stock Connect Program in the future and no assurance that further regulations will not adversely affect the availability of securities under the Stock Connect Program or other operational arrangements. Beginning December 31, 2024 through early January 2025, the China Securities Regulatory Commission (“CSRC”) and the Shanghai and Shenzhen stock exchanges barred several major mutual fund companies from selling shares on a net basis on any day in response to CCP leadership calls to stabilize the Chinese equity market. Although the CSRC has since lifted the restriction, there can be no guarantee that trading in Chinese securities will be free from CCP interference or manipulation in the future. In addition, the Shanghai and Shenzhen markets may be open at a time when the Connect Program is not trading, with the result that prices of China A-shares may fluctuate at times when the Fund is unable to add to or exit its position.

Investments in China A-shares may not be covered by the securities investor protection programs of the exchanges and, without the protection of such programs, will be subject to the risk of default by the broker. In the

18

event that the depository of the Shanghai Stock Exchange and the Shenzhen Stock Exchange defaulted, the Fund may not be able to recover fully its losses from the depository or may be delayed in receiving proceeds as part of any recovery process. In addition, because all trades on the Stock Connect Program in respect of eligible China A-shares must be settled in Renminbi (“RMB”), the Chinese currency, a Fund investing through the Stock Connect Program must have timely access to a reliable supply of offshore RMB, which cannot be guaranteed. The existence of a liquid trading market for China A-shares may depend on whether there is supply of, and demand for, such China A-shares. Market volatility and settlement difficulties in the China A-shares markets may also result in significant fluctuations in the prices of the securities traded on such markets.

China A-shares purchased through the Stock Connect Program are held in nominee name and not the Fund’s name as the beneficial owner. It is possible, therefore, that the Fund’s ability to exercise its rights as a shareholder and to pursue claims against the issuer of China A-shares may be limited because the nominee structure has not been tested in Chinese courts. In addition, the Fund may not be able to participate incorporate actions affecting China A-shares held through the Stock Connect Program due to time constraints or for other operational reasons. Trades on the Stock Connect Program are subject to certain requirements prior to trading. Additionally, there are foreign ownership limitations that may result in limitation on investment or the return of profits if the Fund purchases and sells shares of an issuer in which it owns above a certain threshold determined by China’s securities rules. As a result, the Fund may not be able to execute trading freely in accordance with its investment strategy and the profits that the Fund derives from such investments may be limited.

The Fund may invest in China onshore bonds traded on the China Interbank Bond Market (“CIBM”) through the China – Hong Kong Bond Connect Program (“Bond Connect”). In China, the Central Moneymarkets Unit holds Bond Connect securities on behalf of ultimate investors (such as the Fund) in accounts maintained with a China-based custodian (either the China Central Depository & Clearing Co. or the Shanghai Clearing House). This recordkeeping system subjects the Fund to various risks, including the risks of settlement delays and counterparty default of the China custodian and Hong Kong custody agent. In addition, the Fund may have a limited ability to enforce rights as a bondholder because enforcing the ownership rights of a beneficial holder of Bond Connect securities is untested and courts in China have limited experience in applying the concept of beneficial ownership. Bond Connect uses the trading infrastructure of both Hong Kong and China and is not available on trading holidays in Hong Kong. As a result, prices of securities purchased through Bond Connect may fluctuate at times when the Fund is unable to add to or exit its position. Securities offered through Bond Connect may lose their eligibility for trading through Bond Connect at any time. If Bond Connect securities lose their eligibility for trading through Bond Connect, they may be sold but can no longer be purchased through Bond Connect. Because Bond Connect trades are settled in RMB, a Fund investing through Bond Connect must have timely access to a reliable supply of offshore RMB, which cannot be guaranteed. Market volatility and potential lack of liquidity due to low trading volume of certain bonds on the CIBM may result in prices of such bonds fluctuating significantly, exposing the Fund to liquidity and volatility risks. The bid-ask spreads of the prices of such securities may be large, and the Fund may therefore incur significant costs and may suffer losses when selling such investments. Bonds traded on the CIBM may be difficult or impossible to sell, which may impact the Fund’s ability to acquire or dispose of such securities at their expected prices. Bond Connect is relatively new and its effects on the Chinese interbank bond market are uncertain. Trading through Bond Connect is performed through newly developed trading platforms and operational systems, and in the event of systems malfunctions or extreme market conditions, trading via Bond Connect could be disrupted. There can be no assurance as to Bond Connect’s continued existence or whether future developments regarding Bond Connect (including further interpretation and guidance provided by regulators in Hong Kong and China) may restrict or adversely affect the Fund’s investments or returns. Finally, uncertainties in China tax rules governing taxation of income and gains from investments via Bond Connect could result in unexpected tax liabilities for the Fund.

The Fund’s investments in China may also include investments in US- or Hong Kong-listed issuers that have entered into contractual relationships with a China-based business and/or individuals/entities affiliated with the China-based business through a structure known as a variable interest entity (“VIE”). These arrangements are often used because of Chinese governmental restrictions on non-Chinese ownership of or investment in companies

19

operating in certain sectors in China. Investments in VIEs may pose additional risks because the investment is made through an intermediary listed shell company that has entered into service and other contracts with the underlying Chinese operating company in order to provide investors with exposure to the operating company, and therefore does not represent equity ownership in the operating company. As a result, such investment may limit the rights of an investor with respect to the underlying Chinese operating company. VIEs allow foreign shareholders to exert a degree of control and obtain economic benefits arising from the operating company without formal legal ownership. However, the contractual arrangements between the listed company and the operating company may not be as effective in providing operational control as direct equity ownership, and a foreign investor’s rights may be limited by, for example, actions of the Chinese government which could determine that the underlying contractual arrangements on which control of the VIE is based are invalid or violate Chinese law.

Even though the listed company does not own any equity in the Chinese operating company, the listed company expects to exercise power over and obtain economic rights from the Chinese operating company based on the contractual arrangements. All or most of the value of an investment in these companies depends on the enforceability of the contracts between the listed company and the Chinese operating company. Other risks associated with such investments include the risk that the contractual agreements between the listed company and the Chinese operating company (or its officers, directors, or Chinese equity owners), and any breach thereof, will likely be subject to Chinese law and jurisdiction, which raises questions about whether and how the listed company or its investors could seek recourse in the event of an adverse ruling as to its contractual rights, and that investments in the listed company may be affected by conflicts of interest and duties between the legal owners of the Chinese operating company and the stockholders of the listed company, which may adversely impact the value of investments of the listed company.

The contractual arrangements permit the listed company to include the financial results of the Chinese operating company as a consolidated subsidiary. The listed company often is organized in a jurisdiction other than the U.S. or China (e.g., the Cayman Islands), which likely will not have the same disclosure, reporting, and governance requirements as the U.S. As with other Chinese companies with securities listed on U.S. exchanges, U.S.-listed VIEs and ADRs may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements. Delisting would significantly decrease the liquidity and value of the securities, decrease the ability of the Fund to transact in such securities and may increase the cost of the Fund if required to seek other markets in which to transact in such securities.

Although VIEs are a longstanding industry practice and are well known to Chinese officials and regulatory, historically, they have not been formally recognized under Chinese law and regulations regarding the structure are evolving. Effective March 31, 2023, the CSRC released new rules and implementing guidelines that permit the use of VIE structures, provided they abide by Chinese laws and register with the CSRC. The rules, however, may cause Chinese companies to undergo greater scrutiny and may make the process to create VIEs more difficult and costly. Further, while the rules and implementing guidelines do not prohibit the use of VIE structures, this does not serve as a formal endorsement by the Chinese government. There is a risk that the Chinese government may cease to tolerate VIEs at any time, and any guidance or further rulemaking prohibiting or restricting these structures by the Chinese government, generally or with respect to specific industries, would likely case impacted VIE-structured holding(s) to suffer significant, detrimental and possibly permanent losses, and in turn, adversely affect the Fund’s returns and net asset value. The future of the VIE structure generally and with respect to certain industries remains uncertain.

FOREIGN INVESTMENTS—LIQUIDITY AND TRADING VOLUME RISKS. A Fund that invests a significant percentage of its assets in foreign securities may be subject to the liquidity and trading volume risks associated with international investing. Due to market conditions, including uncertainty regarding the price of a security, it may be difficult for the Fund to buy or sell foreign portfolio securities at a desirable time or price, which could result in investment losses. This risk of portfolio illiquidity is heightened with respect to small- and mid-capitalization securities, generally, and foreign small- and mid-capitalization securities in particular. The Fund may have to lower the selling price, liquidate other investments, or forego another, more appealing

20

investment opportunity as a result of illiquidity in the markets. The Investment Adviser will fair value in good faith any securities it deems to be illiquid under consistently applied procedures established by the Board. Market conditions are always changing and vary by country and industry sector, and investing in international markets involves unique risks. Although it is difficult to accurately assess trends in trading volumes in foreign markets, because some amount of activity has migrated to alternative trading venues, a reduction in trading volumes may pose challenges to the Fund. This is particularly so for a Fund that invest in small- and mid-capitalization companies, which usually have lower trading volumes and take sizeable positions in portfolio companies. As a result of lower trading volumes, it may take longer to buy or sell the securities of such companies, which can exacerbate the Fund’s exposure to volatile markets. The Fund may also be limited in its ability to execute favorable trades in foreign portfolio securities in response to changes in company prices and fundamentals. If the Fund is forced to sell securities to meet redemption requests or other cash needs, or in the case of an event affecting liquidity in a particular market or markets, it may be forced to dispose of those securities under disadvantageous circumstances and at a loss. As the Fund grows in size, these considerations take on increasing significance and may adversely impact performance.

FORWARD COMMITMENTS, WHEN-ISSUED SECURITIES AND DELAYED-DELIVERY TRANSACTIONS. To the extent consistent with its investment objective and strategies, the Fund may purchase securities on a when-issued basis or purchase or sell securities on a forward commitment (sometimes called delayed-delivery) basis. These transactions involve a commitment by the Fund to purchase or sell securities at a future date. The price of the underlying securities (usually expressed in terms of yield) and the date when the securities will be delivered and paid for (the settlement date) are fixed at the time the transaction is negotiated. When-issued purchases and forward commitment transactions normally are negotiated directly with the other party. In addition, recently implemented rule amendments of the Financial Industry Regulatory Authority included mandatory margin requirements that require the Fund to post collateral in connection with its To Be Announced (“TBA”) transactions. There is no similar requirement applicable to the Fund’s TBA counterparties. The required collateralization of TBA trades could increase the cost of TBA transactions to the Fund and impose added operational complexity.

The Fund will purchase securities on a when-issued basis or purchase or sell securities on a forward commitment basis only with the intention of completing the transaction and actually purchasing or selling the securities. If deemed advisable as a matter of investment strategy, however, the Fund may dispose of or negotiate a commitment after entering into it. The Fund also may sell securities it has committed to purchase before those securities are delivered to the Fund on the settlement date. The Fund may realize a capital gain or loss in connection with these transactions.

FUTURES CONTRACTS AND RELATED OPTIONS. To the extent consistent with its investment objective and strategies, the Fund may invest in futures contracts and may purchase and sell call and put options on futures contracts for hedging purposes, to seek to increase total return or for liquidity management purposes, to invest cash balances or dividends or to minimize trading costs; or to gain exposure to certain countries and currencies.

The Investment Adviser, with respect to the Fund, has claimed an exclusion from the definition of the term “commodity pool operator” (“CPO”) under the Commodity Exchange Act, and, therefore, is not subject to registration or regulation as a pool operator under that Act with respect to the Fund. The Fund will engage in transactions in futures contracts and related options only to the extent such transactions are consistent with the requirement of the Internal Revenue Code of 1986, as amended (the “Code”) for maintaining its qualification as a regulated investment company for federal income tax purposes.

With respect to investments in swap transactions, commodity futures, commodity options or certain other derivatives used for purposes other than bona fide hedging purposes, an investment company must meet one of the following tests under the amended regulations in order to claim an exemption from being considered a “commodity pool” or a CPO. First, the aggregate initial margin and premiums required to establish an investment company’s

21

positions in such investments may not exceed five percent (5%) of the liquidation value of the investment company’s portfolio (after accounting for unrealized profits and unrealized losses on any such investments). Alternatively, the aggregate net notional value of such instruments, determined at the time of the most recent position established, may not exceed one hundred percent (100%) of the liquidation value of the investment company’s portfolio (after accounting for unrealized profits and unrealized losses on any such positions). In addition to meeting one of the foregoing trading limitations, the investment company may not market itself as a commodity pool or otherwise as a vehicle for trading in the commodity futures, commodity options or swaps and derivatives markets. In the event that the Investment Adviser was required to register as a CPO, the disclosure and operations of the Fund would need to comply with all applicable CFTC regulations. Compliance with these additional registration and regulatory requirements would increase operational expenses. Other potentially adverse regulatory initiatives could also develop. A related CFTC proposal to harmonize applicable CFTC and SEC regulations could, if adopted, mitigate certain disclosure and operational burdens if CPO registration were required.

When used as a hedge, the Fund may sell a futures contract in order to offset a decrease in the market value of its portfolio securities that might otherwise result from a market decline or currency exchange fluctuations. The Fund may do so either to hedge the value of its portfolio securities as a whole, or to protect against declines, occurring prior to sales of securities, in the value of the securities to be sold. Conversely, the Fund may purchase a futures contract as a hedge in anticipation of a purchase of securities. In addition, the Fund may utilize futures contracts in anticipation of changes in the composition of its portfolio holdings.

Participation in foreign futures and foreign options transactions involves the execution and clearing of trades on or subject to the rules of a foreign board of trade. Neither the National Futures Association (the “NFA”) nor any domestic exchange regulates activities of any foreign boards of trade, including the execution, delivery and clearing of transactions, or has the power to compel enforcement of the rules of a foreign board of trade or any applicable foreign law. This is true even if the exchange is formally linked to a domestic market so that a position taken on the market may be liquidated by a transaction on another market. Moreover, such laws or regulations will vary depending on the foreign country in which the foreign futures or foreign options transaction occurs. For these reasons, persons who trade foreign futures or foreign options contracts may not be afforded certain of the protective measures provided by the Commodity Exchange Act, the CFTC regulations and the rules of the NFA and any domestic exchange, including the right to use reparations proceedings before the CFTC and arbitration proceedings provided them by the NFA or any domestic futures exchange. In particular, the Fund’s investments in foreign futures or foreign options transactions may not be provided the same protections in respect of transactions on U.S. futures exchanges. In addition, the price of any foreign futures or foreign options contract and, therefore, the potential profit and loss thereon may be affected by any variance in the foreign exchange rate between the time an order is placed and the time it is liquidated, offset or exercised.

Certain derivatives traded in over-the-counter (“OTC”) markets, including indexed securities, swaps and OTC options, involve substantial liquidity risk. The absence of liquidity may make it difficult or impossible for the Fund to sell such instruments promptly at an acceptable price. The absence of liquidity may also make it more difficult for the Fund to ascertain a market value for such instruments.

Because derivatives traded in OTC markets are not guaranteed by an exchange or clearing corporation and may not require payment of margin, to the extent that the Fund has unrealized gains in such instruments or has deposited collateral with its counterparty the Fund is at risk that its counterparty will become bankrupt or otherwise fail to honor its obligations. The Fund will attempt to minimize these risks by engaging in transactions in derivatives traded in OTC markets only with financial institutions that have substantial capital or that have provided the Fund with a third-party guaranty or other credit enhancement.

For a further description of futures contracts and related options, see Appendix B to this SAI.

HIGH YIELD FOREIGN SOVEREIGN DEBT SECURITIES. To the extent consistent with its investment objective and strategies, the Fund may purchase high yield foreign sovereign debt securities. Investing in fixed and floating rate high yield foreign sovereign debt securities will expose the Fund to the direct

22

or indirect consequences of political, social or economic changes in the countries that issue the securities. The ability of a foreign sovereign obligor to make timely payments on its external debt obligations will also be strongly influenced by the obligor’s balance of payments, including export performance, its access to international credits and investments, fluctuations in interest rates and the extent of its foreign reserves. Countries such as those in which the Fund may invest have historically experienced, and may continue to experience, high rates of inflation, high interest rates, exchange rate or trade difficulties and extreme poverty and unemployment. Many of these countries are also characterized by political uncertainty or instability (e.g., government instability, poor socioeconomic conditions, corruption, lack of democratic accountability, internal and external conflict, poor quality of bureaucracy, and religious and ethnic tensions). Additional factors that may influence the ability or willingness to service debt include, but are not limited to, a country’s cash flow situation, the availability of sufficient foreign exchange on the date a payment is due, the relative size of its debt service burden to the economy as a whole and its government’s policy towards the International Monetary Fund, the World Bank and other international agencies. A country whose exports are concentrated in a few commodities or whose economy depends on certain strategic imports could be vulnerable to fluctuations in international prices of these commodities or imports. To the extent that a country receives payment for its exports in currencies other than U.S. dollars, its ability to make debt payments denominated in U.S. dollars could be adversely affected. If a foreign sovereign obligor cannot generate sufficient earnings from foreign trade to service its external debt, it may need to depend on continuing loans and aid from foreign governments, commercial banks and multilateral organizations and inflows of foreign investment. The commitment on the part of these foreign governments, multilateral organizations and others to make such disbursements may be conditioned on the government’s implementation of economic reforms and/or economic performance and the timely service of its obligations. Failure to implement such reforms, achieve such levels of economic performance or repay principal or interest when due may result in the cancellation of such third parties’ commitments to lend funds, which may further impair the obligor’s ability or willingness to timely service its debts.

ILLIQUID OR RESTRICTED INVESTMENTS. Pursuant to Rule 22e-4 under the 1940 Act (“Rule 22e-4”), the Fund may invest up to 15% of its net assets in illiquid investments. An illiquid investment as defined in Rule 22e-4 is an investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions within 7 calendar days or less without the sale or disposition significantly changing the market value of the investment. The Fund may purchase commercial paper issued pursuant to Section 4(a)(2) of the 1933 Act and investments that are not registered under the 1933 Act, including restricted securities that can be offered and sold to “qualified institutional buyers” under Rule 144A under the 1933 Act (“Rule 144A securities”) and securities of U.S. and non-U.S. issuers offered through private offerings pursuant to Regulation S of the 1933 Act (“Regulation S securities”). The Investment Adviser will consider whether restricted securities are liquid or illiquid, taking into account relevant market trading and investment-specific considerations consistent with applicable SEC guidance. Investing in Rule 144A securities could increase the level of illiquidity during any period that qualified institutional buyers become uninterested in purchasing these investments. Offerings of Regulation S securities may be conducted outside of the United States, and Regulation S securities may be relatively less liquid as a result of legal or contractual restrictions on resale. Although Regulation S securities may be resold in privately negotiated transactions, the price realized from these sales could be less than that originally paid by the Fund. To the extent an investment held by the Fund is deemed to be an illiquid investment or a less liquid investment, the Fund will be exposed to greater liquidity risk.

The Trust has implemented a liquidity risk management program and related procedures to identify illiquid investments pursuant to Rule 22e-4, and the Trustees have approved the designation of the Investment Adviser to administer the Trust’s liquidity risk management program and related procedures.

The Fund may be limited in pursuing investment opportunities, particularly those in emerging and frontier markets by the limits on its ability to hold illiquid investments. Certain investments trade in lower volume and may be less liquid than securities of large established companies. Because Rule 22e-4 places a limit of 15% of net assets that can be invested in illiquid investments, the Fund may be forced to forego investments in securities that are deemed illiquid.

23

INTERFUND BORROWING AND LENDING. The SEC has granted an exemption permitting the Fund to participate in an interfund borrowing and lending program. This interfund borrowing and lending program allows the Fund to borrow money from other portfolios in the Trust and other affiliated funds of Northern Institutional Funds (each a “Portfolio” and together, the “Portfolios”) advised by NTI, and to lend money to other funds in the Trust, for temporary or emergency purposes. The interfund borrowing and lending program is currently not operational. The interfund borrowing and lending program is subject to a number of conditions, including, among other things, the requirements that (1) a Fund may not borrow or lend money through the program unless it receives a more favorable interest rate than is available from a bank loan rate or investment yield rate, respectively; (2) loans will be secured on an equal priority basis with at least an equivalent percentage of collateral to loan value as any outstanding bank loan that requires collateral; (3) loans will have a maturity no longer than that of any outstanding bank loan (and in any event not over seven days); (4) if an event of default occurs under any agreement evidencing an outstanding bank loan to a Fund, the event of default will automatically (without need for action or notice by the lending fund or Portfolio) constitute an immediate event of default under the Interfund Lending Agreement entitling the lending fund or Portfolio to call the interfund loan (and exercise all rights with respect to any collateral) and that such call will be made if the bank exercises its right to call its loan under its agreement with a Fund ; (5) a Fund may not borrow money if the loan would cause its outstanding borrowings from all sources to exceed 10% of its net assets at the time of the loan, except that a Fund may borrow up to 33 1/3% of its total assets through the program or from other sources if each interfund loan is secured by the pledge of segregated collateral with a market value of at least 102% of the outstanding principal value of the loan; (6) a Fund may not loan money if the loan would cause its aggregate outstanding loans through the program to exceed 15% of its net assets at the time of the loan; (7) a Fund’s interfund loans to any one fund shall not exceed 5% of the lending Fund’s net assets; and (8) a Fund’s borrowings through the program will not exceed the greater of 125% of the Fund’s total net cash redemptions or 102% of the Fund’s sales fails (when a sale of securities “fails” due to circumstances beyond the Fund’s control) for the preceding seven calendar days as measured at the time of the loan. In addition, a Fund may participate in the interfund borrowing and lending program only if and to the extent that such participation is consistent with the Fund’s investment objective and policies. The Board of Trustees of the Trust is responsible for overseeing the interfund borrowing and lending program. A delay in repayment to a lending Fund could result in a lost investment opportunity or additional lending costs.

INTEREST RATE SWAPS, CURRENCY SWAPS, TOTAL RATE OF RETURN SWAPS, CREDIT SWAPS, AND INTEREST RATE FLOORS, CAPS AND COLLARS. To the extent consistent with its investment objective and strategies, the Fund may enter into swap transactions, including interest rate, total rate of return, credit and currency swap transactions, and transactions involving interest rate floors, caps and collars for hedging purposes and/or to seek to increase total return. These instruments are privately negotiated over-the-counter derivative products. A great deal of flexibility is possible in the way these instruments are structured. Interest rate swaps involve the exchange by the Fund with another party of their respective commitments to pay or receive interest, such as an exchange of fixed rate payments for floating rate payments. The purchase of an interest rate floor or cap entitles the purchaser to receive payments of interest on a notional principal amount from the seller, to the extent the specified index falls below (floor) or exceeds (cap) a predetermined interest rate. Interest rate and currency swaps are contracts that obligate the Fund and another party to exchange their rights to pay or receive interest or specified amounts of currency, respectively. Interest rate floors entitle the purchasers to receive interest payments if a specified index falls below a predetermined interest rate. Interest rate caps entitle the purchasers to receive interest payments if a specified index exceeds a predetermined interest rate. An interest rate collar is a combination of a cap and a floor that preserves a certain return within a predetermined range of interest rates. Total rate of return swaps are contracts that obligate a party to pay or receive interest in exchange for the payment by the other party of the total return generated by a security, a basket of securities, an index or an index component. Credit swaps are contracts involving the receipt of floating or fixed rate payments in exchange for assuming potential credit losses of a referenced debt obligation or underlying securities comprising a referenced index. Credit swaps give one party to a transaction the right to dispose of or acquire an asset (or group of assets), or, in the case of credit default swaps, the right to receive or make a payment from the other party, upon the occurrence of specific credit events. Currency swaps involve the exchange of the rights of the Fund and another party to make or receive payments in specific currencies.

24

Some transactions, such as interest rate swaps and total rate of return swaps are entered into on a net basis, i.e.; the two payment streams are netted out, with a Fund receiving or paying, as the case may be, only the net amount of the two payments. If the other party to such a transaction defaults, the Fund’s risk of loss consists of the net amount of payments that the Fund is contractually entitled to receive, if any. In contrast, other transactions involve the payment of the gross amount owed. For example, currency swaps usually involve the delivery of the entire principal amount of one designated currency in exchange for the other designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations.

Credit default swaps are contracts whereby one party makes periodic payments to a counterparty in exchange for the right to receive from the counterparty a payment equal to the par (or other agreed-upon) value of a referenced debt obligation or an underlying security comprising a referenced index in the event of a default by the issuer of the debt obligation or the underlying security comprising the referenced index. The use of credit default swaps may be limited by the Fund’s limitations on illiquid investments.

When used for hedging purposes, the Fund would be the buyer of a credit default swap contract. In that case, the Fund would be entitled to receive the par (or other agreed-upon) value of a referenced debt obligation or an underlying security comprising a referenced index from the counterparty to the contract in the event of a default by a third party, such as a U.S. or non-U.S. issuer, on a debt obligation. In return, the Fund would pay to the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the Fund would have spent the stream of payments and received no benefit from the contract.

When the Fund is the seller of a credit default swap contract, it receives the stream of payments but is obligated to pay upon default of the referenced debt obligation or an underlying security comprising a referenced index. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its total assets, the Fund would be subject to investment exposure on the notional amount of the swap.

In addition to the risks applicable to derivatives generally, credit default swaps involve special risks because they are difficult to value, are highly susceptible to liquidity and credit risk, and generally pay a return to the party that has paid the premium only in the event of an actual default by the issuer of the underlying obligation or an underlying security comprising a referenced index (as opposed to a credit downgrade or other indication of financial difficulty). Credit default swaps also involve credit risk—that the seller may fail to satisfy its payment obligations to the Fund in the event of a default.

The Fund will not enter into a total rate of return, credit, currency or interest rate swap or interest rate floor, cap or collar transaction unless the unsecured commercial paper, senior debt or the claims-paying ability of the other party thereto is rated either A or A-1 or better by S&P or Fitch, or A or Prime-1 or better by Moody’s or a comparable rating from another organization that is recognized as an NRSRO or, if unrated by such rating organization, is determined to be of comparable quality by the Investment Adviser. If there is a default by the other party to such transaction, the Fund will have contractual remedies pursuant to the agreements related to the transaction.

The use of interest rate, total rate of return, credit and currency swaps, as well as interest rate caps, floors and collars, is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Investment Adviser is incorrect in its forecasts of market values, interest rates and currency exchange rates, the investment performance of the Fund would be less favorable than it would have been if these investment techniques were not used.

In addition, these transactions can involve greater risks than if the Fund had invested in the reference obligation directly because, in addition to general market risk, swaps are subject to illiquidity risk, counterparty risk, credit risk and pricing risk. Because they are two party contracts and because they may have terms of greater than

25

seven days, swap transactions may be considered to be illiquid. Moreover, the Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap counterparty. Many swaps are complex and often valued subjectively. Swaps may be subject to pricing or “basis” risk, which exists when a particular swap becomes extraordinarily expensive relative to historical prices or the price of corresponding cash market instruments. Under certain market conditions, it may not be economically feasible to initiate a transaction or liquidate a position in time to avoid a loss or take advantage of an opportunity. If a swap transaction is particularly large or if the relevant market is illiquid, it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses.

The swap market has grown substantially in recent years with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. As a result, the swap market has become relatively liquid in comparison with the markets for other similar instruments that are traded in the interbank market. The Investment Adviser, under the supervision of the Board, is responsible for determining and monitoring the liquidity of the Fund’s transactions in swaps, caps, floors and collars. Under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), certain derivatives will potentially become subject to margin requirements and swap dealers will potentially be required to collect margin from the Fund with respect to such derivatives.

The Dodd-Frank Act and related regulatory developments have imposed comprehensive regulatory requirements on swaps and swap market participants. The regulatory framework includes: (1) registration and regulation of swap dealers and major swap participants; (2) requiring central clearing and execution of standardized swaps; (3) imposing margin requirements on swap transactions; (4) regulating and monitoring swap transactions through position limits and large trader reporting requirements; and (5) imposing recordkeeping and centralized and public reporting requirements, on an anonymous basis, for most swaps. Rules requiring initial margin to be posted by certain market participants for uncleared swaps have been adopted and are being phased in over time. When these rules take effect with respect to the Fund, if the Fund is deemed to have material swaps exposure under applicable swap regulations, it will be required to post initial margin in addition to variation margin. These instruments may be subject to additional regulation as qualified financial contracts (see “Qualified Financial Contracts” below for additional information).

INVESTMENT COMPANIES. To the extent consistent with its investment objective and strategies, the Fund may invest in the securities of other affiliated and unaffiliated investment companies. Investments by the Fund in other investment companies, including ETFs, will be subject to the limitations of the 1940 Act except as permitted by an SEC exemptive order or rule that permits them to invest in certain other investment companies, including ETFs, beyond the limits contained in the 1940 Act, subject to certain terms and conditions. Pursuant to an exemptive order, those limits will not apply to the investment of securities lending collateral by the Fund in certain investment portfolios advised by NTI. In addition, those limits will not apply to the investment of uninvested cash balances in shares of registered or unregistered money market funds whether affiliated or unaffiliated. The foregoing exemption, however, only applies to an unregistered money market fund that (i) limits its investments to those in which a money market fund may invest under Rule 2a-7 of the 1940 Act, and (ii) undertakes to comply with all the other provisions of Rule 2a-7.

Certain investment companies in which the Fund may invest may be new funds. There can be no assurance that a new investment company will grow to an economically viable size, in which case the investment company may cease operations. In such an event, the Fund may be required to liquidate or transfer its investment at an inopportune time.

The Fund may invest uninvested cash in the U.S. Government Portfolio (the “Sweep Portfolio”) of Northern Institutional Funds (“NIF”), an investment company that is advised by NTI.

The Sweep Portfolio seeks to maximize current income to the extent consistent with the preservation of capital and maintenance of liquidity by investing exclusively in high-quality money market instruments. The Sweep Portfolio and the Fund treat investments in the Sweep Portfolio as the purchase and redemption of the

26

Sweep Portfolio’s Shares. A Fund investing in the Sweep Portfolio pursuant to an exemptive order participates equally on a pro rata basis in all income, capital gains and net assets of the Sweep Portfolio, and will have all rights and obligations of a shareholder, as provided in the NIF Trust Agreement, including voting rights. In addition to the management, transfer agency and custody fees payable by the Fund to the Investment Adviser and/or its affiliates, a Fund that invests its uninvested cash in the Sweep Portfolio pursuant to the terms of the exemptive order will bear indirectly a proportionate share of the Sweep Portfolio’s operating expenses, which include the foregoing fees. Currently, the aggregate annual rate of management, transfer agent and custodial fees payable to the Investment Adviser and/or its affiliates on the uninvested cash invested in the Sweep Portfolio is 0.25%. As further discussed herein and consistent with the exemptive order, the Investment Adviser is currently reimbursing the Fund invested in the Sweep Portfolio for the net management fees attributable to advisory services otherwise payable by the Fund on any assets invested in the Sweep Portfolio. The exemptive order requires the Fund’s Board to determine before a vote on the Management Agreement (as defined herein) that the management fees incurred in connection with the investment of uninvested cash in affiliated money market funds are not for duplicative services.

Rule 12d1-4 under the 1940 Act allows a fund to acquire the securities of another investment company in excess of the limitations imposed by Section 12 of the 1940 Act without obtaining an exemptive order from the SEC, subject to certain limitations and conditions. Rule 12d1-4 also is designed to limit the use of complex fund structures. Under Rule 12d1-4, an acquired fund is prohibited from purchasing or otherwise acquiring the securities of another investment company or private fund if, immediately after the purchase, the securities of investment companies and private funds owned by the acquired fund have an aggregate value in excess of 10% of the value of the acquired fund’s total assets, subject to certain limited exceptions. Accordingly, to the extent the Fund’s shares are sold to other investment companies in reliance on Rule 12d1-4, the Fund will be limited in the amount it could invest in other investment companies and private funds. In addition to Rule 12d1-4, the 1940 Act and related rules provide certain other exemptions from these restrictions. If required by the 1940 Act or the rules thereunder, the Fund may expect to vote the shares of other investment companies that are held by it in the same proportion as the vote of all other holders of such securities.

To the extent consistent with its investment objective and strategies, the Fund may invest all or substantially all of its assets in a single open-end investment company or series thereof with substantially the same investment objective, strategy and restrictions as the Fund. However, the Fund currently intends to limit its investments in securities issued by other investment companies to the extent described above. The Fund may adhere to other limitations with respect to its investments in securities issued by other investment companies if required or permitted by the SEC or deemed to be in the best interests of the Trust.

In addition to the fees and expenses that the Fund directly bears, the Fund indirectly bears the fees and expenses of any investment company in which it invests, including affiliated funds. By investing in another investment company, the Fund will be exposed to the investment risks of the investment company in direct proportion to such investment. The investment company may not achieve its investment objective.

LENDING OF SECURITIES. In order to generate additional income, the Fund may lend securities to banks, brokers and dealers or other qualified institutions. In exchange, the borrower provides collateral that is maintained in an amount at least equal to the current market value of the securities loaned. This collateral is marked-to-market on a daily basis. Securities lending may represent no more than one-third of the value of the Fund’s total assets (including the loan collateral).

Collateral for loans of portfolio securities made by the Fund may consist of cash, cash equivalents, or securities issued or guaranteed by the U.S. government or its agencies (or any combination thereof). Any cash collateral received by the Fund in connection with these loans may be invested in a variety of short-term investments, either directly or indirectly through registered or unregistered money market funds that comply with Rule 2a-7 under the 1940 Act. Loan collateral (including any investment of the collateral) is not included in the calculation of the percentage limitations described elsewhere in the Prospectus or SAI regarding the Fund’s investments in particular types of securities.

27

When the Fund lends its securities, it continues to receive payments equal to the dividends and interest paid on the securities loaned and simultaneously may earn interest on the investment of the cash collateral. Investing the collateral subjects it to market depreciation or appreciation, and the Fund is responsible for any loss that may result from its investment of borrowed collateral. Securities lending also subjects the Fund to the risk of loss resulting from problems in the settlement and accounting process, and to additional credit, counterparty and market risk. These risks could be greater with respect to a Fund that loans non-U.S. securities. Additionally, the amount of a Fund’s distributions that qualify for taxation at reduced long-term capital gains rates for individuals, as well as the amount of the Fund’s distributions that qualify for the dividends received deduction available to corporate shareholders (together, “qualifying dividends”) may be reduced as a result of the Fund’s securities lending activities. This is because any dividends paid on securities while on loan will not be deemed to have been received by the Fund, and the equivalent amount paid to the Fund by the borrower of the securities will not be deemed to be a qualifying dividend.

The Fund will have the right to terminate a loan at any time and recall the loaned securities within the normal and customary settlement time for securities transactions. Although voting rights, or rights to consent, attendant to securities on loan pass to the borrower, such loans may be called so that the securities may be voted by the Fund in accordance with policies and procedures approved by the Board and NTI. As with other extensions of credit there are risks of delay in recovering, or even loss of rights in, the collateral should the borrower of the securities fail financially.

Securities lending agreements may be subject to additional regulation as qualified financial contracts (see “Qualified Financial Contracts” for additional information).

Pursuant to an exemptive order issued by the SEC concerning such arrangements, TNTC, an affiliate of the Investment Adviser, renders securities lending services to the Fund. For such services, TNTC receives a percentage of securities lending revenue generated for the Fund. In addition, cash collateral received by the Fund in connection with a securities loan may be invested in shares of other registered or unregistered money market funds that comply with Rule 2a-7 under the 1940 Act, including money market funds that pay investment advisory or other fees to NTI, TNTC or an affiliate.

LIQUIDITY RISK. Liquidity risk is the risk that the Fund will not be able to pay redemption proceeds within the time periods described in a timely manner because of unusual market conditions, an unusually high volume of redemption requests, legal restrictions impairing the Fund’s ability to sell particular securities or close out derivative positions at an advantageous market price or other reasons. Certain portfolio securities may be less liquid than others, which may make them difficult or impossible to sell at the time and the price that the Fund would like or difficult to value. The Fund may have to lower the price, sell other securities instead or forgo an investment opportunity. In addition, less liquid securities may be more difficult to value and markets may become less liquid when there are fewer interested buyers or sellers or when dealers are unwilling or unable to make a market for certain securities. For the same reason, less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities. All of these risks may increase during periods of market turmoil and could have a negative effect on portfolio management or performance. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from money market and other fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity. A Fund with principal investment strategies that involve investments in securities of companies with smaller market capitalizations, foreign securities derivatives or securities with potential market and/or credit risk tend to have the greatest exposure to liquidity risk. All of these risks may increase during periods of market volatility. The liquidity of certain assets, such as privately issued and non-investment grade mortgage- and asset-backed securities, may be difficult to ascertain and may change over time. Transactions in less liquid securities may entail transaction costs that are higher than those for transactions in more liquid securities.

28

MONEY MARKET FUND INVESTMENTS. Certain money market funds in which the Fund may invest calculate their NAV per share to the fourth decimal place (e.g., $1.0000) reflecting market-based values of the money market fund’s holdings. Because the share price of these money market funds will fluctuate, when the Fund sells its shares they may be worth more or less than what the Fund originally paid for them. These money market funds may impose a “liquidity fee” upon the redemption of their shares and generally must impose a fee when net sales of the fund’s shares exceed certain levels. These measures may result in an investment loss or prohibit the Fund from redeeming shares when the Investment Adviser would otherwise redeem shares. If a liquidity fee is imposed, the investing Fund may have to sell other investments at less than opportune times to raise cash to meet shareholder redemptions or for other purposes.

The Fund may also invest in money market funds that operate as “government money market funds” under Rule 2a-7. Government money market funds may seek to maintain a stable price of $1.00 per share and are generally not subject to requirements related to liquidity fees. However, government money market funds typically offer lower yields than other money market funds with fluctuating share prices. Government money market funds face a risk that the money market fund will not be able to maintain a NAV per share of $1.00 at all times. A significant enough market disruption or drop in market prices of securities held by the government money market fund, especially at a time when the fund needs to sell securities to meet shareholder redemption requests, could cause the value of the government money market shares to decrease to a price less than $1.00 per share.

The Fund could lose money invested in a money market fund. An investment in a money market fund, including a government money market fund, is not insured or guaranteed by the fund sponsor, FDIC or any other government agency. A money market fund’s sponsor has no legal obligation to provide financial support to the money market fund, and you should not expect that the sponsor or any person will provide financial support to a money market fund at any time.

Money market funds are subject to comprehensive regulations. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operation, performance and/or yield of money market funds.

NON-DIVERSIFICATION. The Fund is classified as a non-diversified investment company, as defined in the 1940 Act, which means that a relatively high percentage of the Fund’s assets may be invested in the obligations of a limited number of issuers. The value of shares of the Fund may be more susceptible to any single economic, political or regulatory occurrence than the shares of a diversified investment company would be. The Fund intends to satisfy the diversification requirements necessary to qualify as a regulated investment company under the Code, which requires that the Fund be diversified (i.e., not invest more than 5% of its assets in the securities of any one issuer and not more than 10% of the outstanding voting securities of such issuer) as to 50% of its assets. The test does not apply to U.S. government obligations and regulated investment companies.

OBLIGATIONS OF SUPRANATIONAL ENTITIES. To the extent consistent with its investment objective and strategies, the Fund may purchase obligations of supranational entities and invest in obligations of supranational banks. Supranational entities are entities established through the joint participation of several governments, and include the Asian Development Bank, the Inter-American Development Bank, the World Bank, the African Development Bank, the European Economic Community, the European Investment Bank and the Nordic Investment Bank. Many supranational entities are supranational banks, or international banking institutions designed or supported by national governments to promote economic reconstruction, development or trade among nations. The governmental members, or “stockholders,” of supranational entities usually make initial capital contributions to the entity and, in many cases, are committed to make additional capital contributions if the supranational entity is unable to repay its borrowings. There is no guarantee that member countries will continue to make necessary capital contributions to support the supranational entities. If such contributions are not made, the entity may be unable to pay interest or repay principal on its debt securities, and the Fund may lose money on such investments. See also “Foreign Investments—General.”

OPERATIONAL RISK. The Investment Adviser and other Fund service providers may experience disruptions or operating errors arising from factors such as processing errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel, and errors caused by third-party service providers or trading counterparties. In particular, these errors or failures in systems and technology, including operational risks associated with reliance on third party service providers, may affect the Fund’s ability to calculate its NAV in a timely manner, including over a potentially extended period. Moreover, disruptions (for example, pandemics and health crises) that cause prolonged periods of remote work or significant employee absences at the Fund’s service providers could impact the ability to conduct the Fund’s operations. While service providers are required to have appropriate operational risk management policies and procedures, their methods of operational risk management may differ from those of the Fund in the setting of priorities, the personnel and resources available or the effectiveness of relevant controls. The Investment Adviser, through its monitoring and oversight of the other service providers, seeks to ensure that service providers take appropriate precautions to avoid and mitigate risks that could lead to disruptions and operating errors. However, it is not possible for the Investment Adviser or other Fund service providers to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects.

OPTIONS. To the extent consistent with its investment objective and strategies, the Fund may buy and write put and call options. Such options may relate to particular securities, foreign and domestic stock indices, financial instruments, foreign currencies or the yield differential between two securities (“yield curve options”) and may or may not be listed on a domestic or foreign securities exchange or issued by the Options Clearing Corporation. A call option for a particular security or currency gives the purchaser of the option the right to buy, and a writer the obligation to sell, the underlying security at the stated exercise price prior to the expiration of the option, regardless of the market price of the security or currency. The premium paid to the writer is in consideration for undertaking the obligation under the option contract. A put option for a particular security or currency gives the purchaser the right to sell the security or currency at the stated exercise price prior to the expiration date of the option, regardless of the market price of the security or currency. In contrast to an option on a particular security, an option on an index provides the holder with the right to make or receive a cash settlement upon exercise of the option. The amount of this settlement will be equal to the difference between the closing price of the index at the time of exercise and the exercise price of the option expressed in dollars, times a specified multiple.

Options trading is a highly specialized activity that entails greater than ordinary investment risk. Options on particular securities may be more volatile than the underlying instruments and, therefore, on a percentage basis, an investment in options may be subject to greater fluctuation than an investment in the underlying instruments themselves. The use of options to seek to increase total return involves the risk of loss if the Investment Adviser is incorrect in its expectation of fluctuations in securities prices or interest rates. The successful use of options for hedging purposes or to gain exposure to certain countries or currencies also depends in part on the ability of the Investment Adviser to predict future price fluctuations and the degree of correlation between the options and securities markets. If the Investment Adviser is incorrect in its expectation of changes in securities prices or determination of the correlation between the securities indices on which options are written and purchased and the securities in the Fund’s investment portfolio, the investment performance of the Fund will be less favorable than it would have been in the absence of such options transactions. The writing of options could increase the Fund’s portfolio turnover rate and, therefore, associated brokerage commissions or spreads.

The Fund may write covered put and call options and purchase put and call options on foreign currencies in an attempt to protect against declines in the U.S. dollar value of foreign portfolio securities and against increases in the U.S. dollar cost of foreign securities to be acquired. The Fund may also use options on currency to cross-hedge, which involves writing or purchasing options on one currency to seek to hedge against changes in exchange rates for a different currency with a pattern of correlation. As with other kinds of option transactions, however, the writing of an option on foreign currency will constitute only a partial hedge, up to the amount of the premium received. If an option that the Fund has written is exercised, it could be required to purchase or sell foreign currencies at disadvantageous exchange rates, thereby incurring losses. The purchase of an option on

30

foreign currency may constitute an effective hedge against exchange rate fluctuations; however, in the event of exchange rate movements adverse to the Fund’s position, it may forfeit the entire amount of the premium plus related transaction costs. Options on foreign currencies may be traded on U.S. and foreign exchanges or over-the-counter. In addition, the Fund may purchase call options on currency to seek to increase total return.

The Fund’s obligation to sell or purchase a security or currency underlying an option contract written by it may be terminated prior to the expiration date of the option by the Fund’s execution of a closing purchase transaction, which is effected by purchasing on an exchange an option of the same series (i.e., same underlying security or currency, exercise price and expiration date) as the option previously written. Such a purchase does not result in the ownership of an option. A closing purchase transaction will ordinarily be effected to realize a profit on an outstanding option, to prevent an underlying instrument from being called, to permit the sale of the underlying security or currency or to permit the writing of a new option containing different terms on such underlying security or currency. The cost of such a liquidation purchase plus the associated transaction costs may be greater than the premium received from writing the original option, in which event the Fund will have incurred a loss in the transaction. There is no assurance that a liquid secondary market will exist for any particular option. An option writer, unable to effect a closing purchase transaction, will not be able to sell the underlying security or currency (in the case of a call option) or liquidate the segregated assets (in the case of a put option) until the option expires or the optioned security or currency is delivered upon exercise with the result that the writer in such circumstances will be subject to the risk of market decline or appreciation in the instrument during such period.

When the Fund purchases an option, the premium paid by it is recorded as an asset of the Fund. When the Fund writes an option, an amount equal to the net premium (the premium less the commission) received by the Fund is included in the liability section of the Fund’s statement of assets and liabilities as a deferred credit. The amount of this asset or deferred credit will be subsequently marked-to-market to reflect the current value of the option purchased or written. The current value of the traded option is the last sale price or, in the absence of a sale, the current bid price. If an option purchased by the Fund expires unexercised, the Fund realizes a loss equal to the premium paid. If the Fund enters into a closing sale transaction on an option purchased by it, the Fund will realize a gain if the premium received by the Fund on the closing transaction is more than the premium paid to purchase the option, or a loss if it is less. If an option written by the Fund expires on the stipulated expiration date or if the Fund enters into a closing purchase transaction, it will realize a gain (or loss if the cost of a closing purchase transaction exceeds the net premium received when the option is sold) and the deferred credit related to such option will be eliminated. If an option written by the Fund is exercised, the proceeds of the sale will be increased by the net premium originally received and the Fund will realize a gain or loss.

There are several risks associated with transactions in certain options. For example, there are significant differences between the securities, currency and options markets that could result in an imperfect correlation between these markets, causing a given transaction not to achieve its objectives. In addition, a liquid secondary market for particular options, whether traded over-the-counter or on an exchange, may be absent for reasons that include the following: there may be insufficient trading interest in certain options; restrictions may be imposed by an exchange on opening transactions or closing transactions or both; trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options or underlying securities or currencies; unusual or unforeseen circumstances may interrupt normal operations on an exchange; the facilities of an exchange or the Options Clearing Corporation may not at all times be adequate to handle current trading value; or one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of options (or a particular class or series of options), in which event the secondary market on that exchange (or in that class or series of options) would cease to exist, although outstanding options that had been issued by the Options Clearing Corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

Transactions by the Fund in options will be subject to limitations established by each of the exchanges, boards of trade or other trading facilities on which such options are traded governing the maximum number of options in each class which may be written or purchased by a single investor or group of investors acting in

31

concert regardless of whether the options are written or purchased on the same or different exchanges, boards of trade or other trading facilities or are held in one or more accounts or through one or more brokers. Thus, the number of options that the Fund may write or purchase may be affected by options written or purchased by other investment advisory clients of the Investment Adviser. An exchange, board of trade or other trading facility may order the liquidation of positions found to be in excess of these limits, and it may impose certain other sanctions.

Special Risks Associated with Options on Currency. An exchange-traded option position may be closed out only on an options exchange that provides a secondary market for an option of the same series. There is no assurance that a liquid secondary market on an exchange will exist for any particular option or at any particular time. For some options, no secondary market on an exchange may exist. In such event, it might not be possible to effect closing transactions in particular options, with the result that the Fund would have to exercise its options in order to realize any profit and would incur transaction costs upon the sale of underlying securities pursuant to the exercise of its options. If the Fund, as a call option writer, is unable to effect a closing purchase transaction in a secondary market, it will not be able to sell the underlying currency (or security quoted or denominated in that currency), or dispose of the segregated assets, until the option expires or it delivers the underlying currency upon exercise.

The amount of the premiums that the Fund may pay or receive, may be adversely affected as new or existing institutions, including other investment companies, engage in or increase their option purchasing and writing activities.

PRIVATIZATIONS. Privatizations are foreign government programs for selling all or part of the interests in government-owned or controlled enterprises. The ability of a U.S. entity to participate in privatizations in certain foreign countries may be limited by local law or the terms on which the Fund may be permitted to participate may be less advantageous than those applicable for local investors. There can be no assurance that foreign governments will continue to sell their interests in companies currently owned or controlled by them or that privatization programs will be successful.

QUALIFIED FINANCIAL CONTRACTS. Regulations adopted by federal banking regulators under the Dodd-Frank Act, which took effect in 2019, require that certain qualified financial contracts (“QFCs”) with counterparties that are part of U.S. or foreign global systemically important banking organizations be amended to include contractual restrictions on close-out and cross-default rights. QFCs include, but are not limited to, securities contracts, commodities contracts, forward contracts, repurchase agreements, securities lending agreements and swaps agreements, as well as related master agreements, security agreements, credit enhancements, and reimbursement obligations. If a covered counterparty of the Fund or certain of the covered counterparty’s affiliates were to become subject to certain insolvency proceedings, the Fund may be temporarily unable to exercise certain default rights, and the QFC may be transferred to another entity. These requirements may impact the Fund’s credit and counterparty risks.

REAL ESTATE INVESTMENT TRUSTS. To the extent consistent with its investment objective and strategies, the Fund may invest in REITs. REITs are pooled investment vehicles that invest primarily in real estate or real estate related loans. REITs are generally classified as equity REITs, mortgage REITs or a combination of equity and mortgage REITs. Equity REITs invest the majority of their assets directly in real property and derive income primarily from the collection of rents. Equity REITs can also realize capital gains by selling properties that have appreciated in value. Equity REITs may further be categorized by the type of real estate securities they own, such as apartment properties, retail shopping centers, office and industrial properties, hotels, healthcare facilities, manufactured housing and mixed property types. Mortgage REITs invest the majority of their assets in real estate mortgages and derive income from the collection of interest payments. Hybrid REITs combine the characteristics of both equity and mortgage REITs. Like a regulated investment company such as the Fund, REITs are not taxed on income distributed to shareholders provided they comply with certain requirements under the Code. The Fund will indirectly bear its proportionate share of any expenses paid by REITs in which it invests in addition to the expenses paid by the Fund.

32

Investing in REITs involves certain unique risks. Equity REITs may be affected by changes in the value of the underlying property owned by such REITs, while mortgage REITs may be affected by the quality of any credit extended. REITs are dependent upon management skills, are not diversified (except to the extent the Code requires), and are subject to the risks of financing projects. REITs are subject to heavy cash flow dependency, default by borrowers, self-liquidation, and the possibilities of failing to qualify for the exemption from tax for distributed income under the Code and failing to maintain their exemptions from the 1940 Act. REITs (especially mortgage REITs) are also subject to interest rate risks. Investing in REITs also involves risks similar to those associated with investing in small capitalization companies. That is, they may have limited financial resources, may trade less frequently and in a limited volume and may be subject to abrupt or erratic price movements in comparison to larger capitalization companies. To the extent that assets underlying a REIT are concentrated geographically, by property type or in certain other respects such as location, these risks may be heightened.

In addition, the value of such securities may fluctuate in response to the market’s perception of the creditworthiness of the issuers of mortgage-related securities owned by the Fund. Because investments in mortgage-related securities are interest sensitive, the ability of the issuer to reinvest or to reinvest favorably in underlying mortgages may be limited by government regulation or tax policy. For example, action by the Board of Governors of the Federal Reserve System to limit the growth of the nation’s money supply may cause interest rates to rise and thereby reduce the volume of new residential mortgages. Additionally, although mortgages and mortgage-related securities are generally supported by some form of government or private guarantees and/or insurance, there is no assurance that private guarantors or insurers will be able to meet their obligation.

REITs (especially mortgage REITs) are also subject to interest rate risks. When interest rates decline, the value of a REIT’s investments in fixed rate obligations can be expected to rise. Conversely, when interest rates rise, the value of a REIT’s investments in fixed rate obligations can be expected to decline. In contrast, as interest rates on adjustable rate mortgage loans are reset periodically, yields on a REIT’s investments in such loans will gradually align themselves to reflect changes in market interest rates, causing the value of such investments to fluctuate less dramatically in response to interest rate fluctuations than would investments in fixed rate obligations.

The REIT investments of the Fund may not provide complete tax information to the Fund until after the calendar year-end. Consequently, because of the delay, it may be necessary for the Fund to request permission to extend the deadline for issuance of Forms 1099-DIV beyond January 31. Also, under current provisions of the Code, distributions attributable to operating income of REITs in which the Fund invests are not eligible for favorable tax treatment as long-term capital gains and will be taxable to you as ordinary income. The Fund, however, may designate such distributions as “section 199A dividends” to the extent of the excess of the ordinary REIT dividends, other than capital gain dividends and portions of REIT dividends designated as qualified dividend income, that the Fund receives from a REIT for a taxable year over the Fund’s expenses allocable to such dividends. Section 199A dividends may be taxed to individuals and other non-corporate shareholders at a reduced effective federal income tax rate, provided you have satisfied a holding period requirement for the Fund’s shares and satisfied certain other conditions.

REAL ESTATE SECURITIES. To the extent consistent with its investment objective and strategies, the Fund may invest in real estate securities. The performance of real estate securities may be significantly impacted by the performance of real estate markets. Property values may fall due to increasing vacancies or declining rents resulting from economic, legal, cultural or technological developments. The price of real estate company shares also may drop because of the failure of borrowers to pay their loans and poor management. Many real estate companies utilize leverage, which increases investment risk and could adversely affect a company’s operations and market value in periods of rising interest rates as well as risks normally associated with debt financing. Real property investments are subject to varying degrees of risk. The yields available from investments in real estate depend on the amount of income and capital appreciation generated by the related properties. Income and real estate values may also be adversely affected by such factors as applicable domestic and foreign laws (e.g., Americans with Disabilities Act and tax laws), interest rate levels and the availability of financing. If the

33

properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of the real estate company to make payments of any interest and principal on its debt securities will be adversely affected. In addition, real property may be subject to the quality of credit extended and defaults by borrowers and tenants. The performance of the economy in each of the countries and regions in which the real estate owned by the Fund is located affects occupancy, market rental rates and expenses and, consequently, has an impact on the income from such properties and their underlying values. The financial results of major local employers also may have an impact on the cash flow and value of certain properties. In addition, real estate investments are relatively illiquid and, therefore, the ability of real estate companies to vary their portfolios promptly in response to changes in economic or other conditions is limited. A real estate company such as a REIT may also have joint venture investments in certain of its properties and, consequently, its ability to control decisions relating to such properties may be limited.

REPURCHASE AGREEMENTS. To the extent consistent with its investment objective and strategies, the Fund may agree to purchase portfolio securities from domestic and foreign financial institutions subject to the seller’s agreement to repurchase them at a mutually agreed upon date and price (“repurchase agreements”). Repurchase agreements may be considered to be loans under the 1940 Act. Although the securities subject to a repurchase agreement may bear maturities exceeding one year, settlement for the repurchase agreement generally will not be more than one year after a Fund’s acquisition of the securities and normally will be within a shorter period of time. Securities subject to repurchase agreements normally are held either by the Trust’s custodian or subcustodian (if any), or in the Federal Reserve/Treasury Book-Entry System.

The Fund may permit the seller’s obligation to be novated to the Fixed Income Clearing Corporation (“FICC”) pursuant to an agreement among the Fund, FICC and the seller as a sponsoring member of FICC. In such case, FICC would become the Fund’s counterparty. The Fund will make payment for such securities only upon physical delivery or evidence of book-entry transfer to the account of the sponsoring member, the custodian or a bank acting as agent for the Fund. The Fund would become subject to FICC’s rules, which may limit the Fund’s rights and remedies (including recourse to collateral) or delay or restrict the rights and remedies, and expose the Fund to the risk of FICC’s insolvency.

The seller under a repurchase agreement will be required to maintain the value of the securities subject to the agreement in an amount exceeding the repurchase price (including accrued interest). Default by the seller or FICC would, however, expose the Fund to possible loss because of adverse market action or delay in connection with the disposition of the underlying obligations. In addition, in the event of a bankruptcy, the Fund could suffer additional losses if a court determines that the Fund’s interest in the collateral is unenforceable. If the Fund enters into a repurchase agreement involving securities as collateral that the Fund could not purchase directly, and the counterparty defaults, the Fund may become the holder of securities that it could not purchase. Apart from the risks associated with bankruptcy or insolvency proceedings, there is also the risk that the seller or FICC may fail to repurchase the security. If the market value of the securities subject to the repurchase agreement becomes less than the repurchase price (including accrued interest), generally, the seller of the securities or FICC will be required to deliver additional securities so that the market value of all securities subject to the repurchase agreement equals or exceeds the repurchase price. Repurchase agreements may be subject to additional regulation as qualified financial contracts (see “Qualified Financial Contracts” above for additional information).

In the event of default by a foreign counterparty in a repurchase agreement, the Fund may be unable to successfully assert a claim to the collateral under foreign laws. As a result, repurchase agreements with a foreign financial institution may involve higher credit risks than repurchase agreements with domestic financial institutions. Moreover, certain foreign countries may have less developed and less regulated banking systems and auditing, accounting and financial reporting systems than the U.S. In addition, repurchase agreements with foreign financial institutions located in emerging markets, or relating to emerging markets, may involve foreign financial institutions or counterparties with lower credit ratings than domestic financial institutions. (See also “Foreign Investments—General” for additional discussion of the risks of investments with foreign institutions).

34

REVERSE REPURCHASE AGREEMENTS. To the extent consistent with its investment objective and strategies, the Fund may borrow funds by selling portfolio securities to financial institutions such as banks and broker/dealers and agreeing to repurchase them at a mutually specified date and price (“reverse repurchase agreements”). The Fund may use the proceeds of reverse repurchase agreements to purchase other securities either maturing, or under an agreement to resell, on a date simultaneous with or prior to the expiration of the reverse repurchase agreement. Reverse repurchase agreements are considered to be borrowings under the 1940 Act. The use of reverse repurchase agreements may be regarded as leveraging and, therefore, speculative. Furthermore, reverse repurchase agreements involve the risks that (i) the interest income earned in the investment of the proceeds will be less than the interest expense, (ii) the market value of the securities retained in lieu of sale by a Fund may decline below the price of the securities the Fund has sold but is obligated to repurchase, (iii) the market value of the securities sold will decline below the price at which the Fund is required to repurchase them and (iv) the securities will not be returned to the Fund. The Fund will pay interest on amounts obtained pursuant to a reverse repurchase agreement.

In addition, if the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, such buyer or its trustee or receiver may receive an extension of time to determine whether to enforce the Fund’s obligations to repurchase the securities and the Fund’s use of the proceeds of the reverse repurchase agreement may effectively be restricted pending such decision.

Reverse repurchase agreements may be subject to additional regulation as qualified financial contracts (see “Qualified Financial Contracts” for additional information).

RISKS RELATED TO SMALL AND MID-CAPITALIZATION COMPANY SECURITIES. To the extent consistent with its investment objective and strategies, the Fund may invest in small and mid-capitalization company securities. While the Investment Adviser or a Sub-Adviser may believe that smaller and mid-capitalization companies can provide greater growth potential than larger, more mature firms, investing in the securities of such companies also involves greater risk, portfolio price volatility and cost. Securities of such issuers may lack sufficient market liquidity to enable the Fund to effect sales at an advantageous time or without a substantial drop in price. Small and mid-capitalization companies often have narrower markets and more limited managerial and financial resources than larger, more established companies and may have a greater sensitivity to changing economic conditions. Smaller and mid-capitalization companies also face a greater risk of business failure. As a result, their performance can be more volatile, which could increase the volatility of the Fund’s portfolio. Generally, the smaller the company’s size, the greater these risks.

The values of small and mid-capitalization company stocks will frequently fluctuate independently of the values of larger company stocks. Small and mid-capitalization company stocks may decline in price as large company stock prices rise, or rise in price as large company stock prices decline. You should, therefore, expect that the NAV of a Fund that invests in such stocks will be more volatile than, and may fluctuate independently of, broad stock market indices such as the S&P 500 Index.

The additional costs associated with the acquisition of small and mid-capitalization company stocks include brokerage costs, market impact costs (that is, the increase in market prices which that may result when a Fund purchases thinly traded stock) and the effect of the “bid-ask” spread in small and mid-capitalization company stocks. These costs will be borne by all shareholders and may negatively impact investment performance.

SHORT SALES AGAINST-THE-BOX. To the extent consistent with its investment objective and policies, the Fund may engage in short sales “against-the-box.” In a short sale, the seller sells a borrowed security and has a corresponding obligation to the lender to deliver the identical security. The seller does not immediately return the securities sold and is said to have a short position in those securities until delivery occurs. While a short sale is made by selling a security the seller does not own, a short sale is “against-the-box” to the extent that the seller contemporaneously owns or has the right to obtain, at no added cost, securities identical to those sold short. It may be entered into by the Fund, for example, to lock in a sales price for a security the Fund does not

35

wish to sell immediately. If the Fund sells securities short against-the-box, it may protect itself from loss if the price of the security declines in the future, but will lose the opportunity to profit on such securities if the price rises.

SOVEREIGN DEBT. To the extent consistent with its investment objective and strategies, the Fund may invest in sovereign debt securities. The cost of servicing external debt will also generally be adversely affected by rising international interest rates because many external debt obligations bear interest at rates that are adjusted based upon international interest rates. The debtor’s willingness or ability to repay in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its non-U.S. reserves, the availability of sufficient non-U.S. exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the sovereign debtor’s policy toward principal international lenders and the political constraints to which the sovereign debtor may be subject. Sovereign debtors also may be dependent on expected disbursements from foreign governments or multinational agencies, the country’s access to trade and other international credits, and the country’s balance of trade. Some emerging market sovereign debtors have in the past rescheduled their debt payments or declared moratoria on payments, and similar occurrences may happen in the future. There is no bankruptcy proceeding by which sovereign debt on which governmental entities have defaulted may be collected in whole or in part. The ability to service external debt will also depend on the level of the relevant government’s international currency reserves and its access to foreign exchange. Currency devaluations may affect the ability of a sovereign obligor to obtain sufficient foreign exchange to service its external debt.

As a result of the foregoing or other factors, a governmental obligor may default on its obligations. If such an event occurs, the Fund may have limited legal recourse against the issuer and/or guarantor. Remedies must, in some cases, be pursued in the courts of the defaulting party itself, and the ability of the holder of foreign sovereign debt securities to obtain recourse may be subject to the political climate in the relevant country. In addition, no assurance can be given that the holders of commercial bank debt will not contest payments to the holders of other foreign sovereign debt obligations in the event of default under their commercial bank loan agreements.

SPECIALIZED OWNERSHIP VEHICLES. Specialized ownership vehicles pool investors’ funds for investment and are primarily used to invest in income-producing real estate or real estate related loans or interests. Such specialized ownership vehicles in which the Fund may invest include property unit trusts, REITs and other similar specialized investment vehicles. Investments in such specialized ownership vehicles may have favorable or unfavorable legal, regulatory or tax implications for the Fund and, to the extent such vehicles are structured similarly to investment funds, a shareholder in the Fund will bear not only his or her proportionate share of the expenses of the Fund, but also, indirectly the expenses of the specialized ownership vehicle.

STANDBY COMMITMENTS. The Fund may enter into standby commitments with respect to municipal instruments held by them. Under a standby commitment, a dealer agrees to purchase at the Fund’s option a specified municipal instrument. Standby commitments may be exercisable by the Fund at any time before the maturity of the underlying municipal instruments and may be sold, transferred or assigned only with the instruments involved.

The Fund expects that standby commitments generally will be available without the payment of any direct or indirect consideration. However, if necessary or advisable, the Fund may pay for a standby commitment either separately in cash or by paying a higher price for municipal instruments that are acquired subject to the commitment (thus reducing the yield to maturity otherwise available for the same securities). The total amount paid in either manner for outstanding standby commitments held by a Fund will not exceed 1/2 of 1% of the value of the Fund’s total assets calculated immediately after each standby commitment is acquired.

The Fund intends to enter into standby commitments only with dealers, banks and broker-dealers which, in the Investment Adviser’s opinion present minimal credit risks. The Fund will acquire standby commitments solely to facilitate portfolio liquidity and do not intend to exercise their rights thereunder for trading purposes.

36

The acquisition of a standby commitment will not affect the valuation of the underlying municipal instrument. The actual standby commitment will be valued at zero in determining NAV. Accordingly, where the Fund pay directly or indirectly for a standby commitment, the Fund’s costs will be reflected as an unrealized loss for the period during which the commitment is held by the Fund and will be reflected in realized gain or loss when the commitment is exercised or expires.

STRIPPED SECURITIES. To the extent consistent with its investment objective and strategies, the Fund may purchase stripped securities. The U.S. Treasury has facilitated transfers of ownership of zero coupon securities by accounting separately for the beneficial ownership of particular interest coupon and principal payments on U.S. Treasury securities through the Federal Reserve book-entry record-keeping system. The Federal Reserve program as established by the U.S. Treasury is known as “Separate Trading of Registered Interest and Principal of Securities” or “STRIPS.” The Fund may purchase securities registered in the STRIPS program. Under the STRIPS program, the Fund will be able to have its beneficial ownership of zero coupon securities recorded directly in the book-entry record-keeping system in lieu of having to hold certificates or other evidences of ownership of the underlying U.S. Treasury securities.

Other types of stripped securities may be purchased by the Fund, including stripped mortgage-backed securities (“SMBS”). SMBS usually are structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed obligations. A common type of SMBS will have one class receiving all of the interest, while the other class receives all of the principal. However, in some instances, one class will receive some of the interest and most of the principal while the other class will receive most of the interest and the remainder of the principal. If the underlying obligations experience greater than anticipated prepayments of principal, the Fund may fail to recoup fully its initial investment in these securities. The market value of the class consisting entirely of principal payments generally is extremely volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest generally are higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns also are volatile and there is a risk that the initial investment will not be recouped fully. SMBS issued by the U.S. government (or a U.S. government agency, instrumentality or sponsored enterprise) may be considered liquid under guidelines established by the Board if they can be disposed of in the ordinary course of business within seven calendar days at approximately the value ascribed to it by the Fund.

TEMPORARY INVESTMENTS. Northern Trust US Equity ETF temporarily may hold cash and/or invest in short-term obligations including U.S. government obligations, high quality money market instruments (including commercial paper and obligations of foreign and domestic banks such as certificates of deposit, bank and deposit notes, bankers’ acceptances and fixed time deposits), and repurchase agreements with maturities of 13 months or less. The Fund temporarily may hold cash or invest all or any portion of its assets in short-term obligations pending investment or to meet anticipated redemption requests. The Fund also may hold cash or invest in short-term obligations as a temporary measure mainly designed to limit the Fund’s losses in response to adverse market, economic or other conditions when the Investment Adviser believes that it is in the best interest of the Fund to pursue such defensive strategy. The Investment Adviser may, however, choose not to make such temporary investments even in very volatile or adverse conditions. The Fund may not achieve its investment objective when it holds cash or invests its assets in short-term obligations or otherwise make temporary investments. The Fund also may miss investment opportunities and have a lower total return during these periods. Maintaining cash positions may also subject the Fund to increased credit risk exposure to the Fund’s custodian bank.

U.S. GOVERNMENT OBLIGATIONS. Examples of the types of U.S. government obligations that may be acquired by the Fund include U.S. Treasury Bills, Treasury Notes and Treasury Bonds. The Fund also may acquire obligations of Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, the Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the U.S., Small Business Administration, Fannie Mae, Ginnie Mae, General Services Administration, Central Bank for Cooperatives, Freddie Mac, Federal Intermediate Credit Banks and the Maritime Administration.

Securities guaranteed as to principal or interest by the U.S. government or by its agencies, instrumentalities or sponsored enterprises also are deemed to include (i) securities for which the payment of principal and interest is backed by an irrevocable letter of credit issued by the U.S. government or by any agency, instrumentality or sponsored enterprise thereof, and (ii) participations in loans made to foreign governments or their agencies that are so guaranteed.

To the extent consistent with its investment objective and strategies, the Fund may invest in a variety of U.S. Treasury obligations and obligations issued by or guaranteed by the U.S. government or by its agencies, instrumentalities or sponsored enterprises. Not all U.S. government obligations carry the same credit support. No assurance can be given that the U.S. government would provide financial support to its agencies, instrumentalities or sponsored enterprises if it were not obligated to do so by law. There is no assurance that these commitments will be undertaken or complied with in the future. The maximum potential liability of the issuers of some U.S. government securities may greatly exceed their current resources, including any legal right to support from the U.S. Treasury. In addition, the secondary market for certain participations in loans made to foreign governments or their agencies may be limited. In the absence of a suitable secondary market, such participations are generally considered illiquid.

From time to time, uncertainty regarding the status of negotiations in the U.S. government to increase the statutory debt ceiling could: increase the risk that the U.S. government may default on payments on certain U.S. government securities; cause the credit rating of the U.S. government to be downgraded or increase volatility in both stock and bond markets; result in higher interest rates; reduce prices of U.S. Treasury securities; and/or increase the costs of certain kinds of debt. For example, in August 2023, Fitch Ratings downgraded the U.S.’s long-term foreign credit issuer default rating to AA+ from AAA, citing expected fiscal deterioration over the next three years.

Many states grant tax-free status to dividends paid to shareholders of a fund from interest income earned by that fund from direct obligations of the U.S. government, subject in some states to minimum investment requirements that must be met by the fund. Investments in securities issued by Ginnie Mae or Fannie Mae, bankers’ acceptances, commercial paper and repurchase agreements collateralized by U.S. Government securities do not generally qualify for tax-free treatment.

VARIABLE AND FLOATING RATE INSTRUMENTS. To the extent consistent with its investment objective and strategies, the Fund may invest in variable and floating rate instruments. Variable and floating rate instruments have interest rates that periodically are adjusted either at set intervals or that float at a margin in relation to a generally recognized index rate. These instruments include long-term floating rate public obligations of the U.S. Treasury and variable and floating rate bonds (sometimes referred to as “put bonds”) where the Fund obtains at the time of purchase the right to put the bond back to the issuer or a third party at par at a specified date and also includes leveraged inverse floating rate instruments (“inverse floaters”).

All variable or floating rate instruments will meet the applicable rating standards of the Fund. The Investment Adviser may determine that a variable or floating rate obligation meets the Fund’s rating standards by reason of being backed by a letter of credit or guarantee issued by a bank that meets those rating standards.

Variable and floating rate instruments that may be purchased by the Fund include variable amount master demand notes, which permit the indebtedness thereunder to vary in addition to providing for periodic adjustments in the interest rate. Variable and floating rate instruments also include leveraged inverse floaters. The interest rate on an inverse floater resets in the opposite direction from the market rate of interest to which the inverse floater is indexed. An inverse floater may be considered to be leveraged to the extent that its interest rate varies by a magnitude that exceeds the magnitude of the change in the index rate of interest. The higher degree of leverage inherent in inverse floaters is associated with greater volatility in their market values. Accordingly, the duration of an inverse floater may exceed its stated final maturity. The Fund may deem the maturity of variable and floating rate instruments to be less than its stated maturities based on their variable and floating rate features and/

38

or their put features. Unrated variable and floating rate instruments will be determined by the Investment Adviser to be of comparable quality at the time of purchase to rated instruments that may be purchased by the Fund.

Variable and floating rate instruments including inverse floaters held by the Fund will be subject to the Fund’s limitation on illiquid investments, absent a reliable trading market, when the Fund may not demand payment of the principal amount within seven days. Because there is no active secondary market for certain variable and floating rate instruments, they may be more difficult to sell if the issuer defaults on its payment obligations or during periods when the Fund is not entitled to exercise its demand rights. As a result, the Fund could suffer a loss with respect to these instruments.

WARRANTS. To the extent consistent with its investment objective and strategies, the Fund may purchase warrants and similar rights, which are privileges issued by corporations enabling the owners to subscribe to and purchase a specified number of shares of the corporation at a specified price during a specified period of time. The prices of warrants do not necessarily correlate with the prices of the underlying shares. The purchase of warrants involves the risk that the Fund could lose the purchase value of a warrant if the right to subscribe to additional shares is not exercised prior to the warrant’s expiration. Also, the purchase of warrants involves the risk that the effective price paid for the warrant added to the subscription price of the related security may exceed the value of the subscribed security’s market price such as when there is no movement in the level of the underlying security.

YIELDS AND RATINGS. The yields on certain obligations, including the instruments in which the Fund may invest, are dependent on a variety of factors, including general market conditions, conditions in the particular market for the obligation, financial condition of the issuer, size of the offering, maturity of the obligation and ratings of the issue. The ratings of S&P, DBRS, Moody’s and Fitch represent their respective opinions as to the quality of the obligations they undertake to rate. Ratings, however, are general and are not absolute standards of quality. Consequently, obligations with the same rating, maturity and interest rate may have different market prices. For a more complete discussion of ratings, see Appendix A to this SAI.

Subject to the limitations stated in the Prospectus, if a security held by the Fund undergoes a rating revision, the Fund may continue to hold the security if the Investment Adviser determines such retention is warranted.

ZERO COUPON AND CAPITAL APPRECIATION BONDS AND PAY-IN-KIND SECURITIES. To the extent consistent with its investment objective and strategies, the Fund may invest in zero coupon bonds, capital appreciation bonds and pay-in-kind (“PIK”) securities. Zero coupon and capital appreciation bonds are debt securities issued or sold at a discount from their face value and that do not entitle the holder to any periodic payment of interest prior to maturity or a specified date. The original issue discount varies depending on the time remaining until maturity or cash payment date, prevailing interest rates, the liquidity of the security and the perceived credit quality of the issuer. These securities also may take the form of debt securities that have been stripped of their unmatured interest coupons, the coupons themselves or receipts or certificates representing interests in such stripped debt obligations or coupons. The market prices of zero coupon bonds, capital appreciation bonds and PIK securities generally are more volatile than the market prices of interest bearing securities and are likely to respond to a greater degree to changes in interest rates than interest bearing securities having similar maturities and credit quality.

PIK securities may be debt obligations or preferred shares that provide the issuer with the option of paying interest or dividends on such obligations in cash or in the form of additional securities rather than cash. Similar to zero coupon bonds, PIK securities are designed to give an issuer flexibility in managing cash flow. PIK securities that are debt securities can either be senior or subordinated debt and generally trade flat (i.e., without accrued interest). The trading price of PIK debt securities generally reflects the market value of the underlying debt plus an amount representing accrued interest since the last interest payment.

39

Zero coupon bonds, capital appreciation bonds and PIK securities involve the additional risk that, unlike securities that periodically pay interest to maturity, the Fund will realize no cash until a specified future payment date unless a portion of such securities is sold and, if the issuer of such securities defaults, the Fund may obtain no return at all on its investment. In addition, even though such securities do not provide for the payment of current interest in cash, the Fund is nonetheless required to accrue income on such investments for each taxable year and generally is required to distribute such accrued amounts (net of deductible expenses, if any) to avoid being subject to tax. Because no cash generally is received at the time of the accrual, the Fund may be required to liquidate other portfolio securities to obtain sufficient cash to satisfy federal tax distribution requirements applicable to the Fund.

INVESTMENT RESTRICTIONS

The Fund is subject to the fundamental investment restrictions enumerated below which may be changed only by a vote of the holders of a majority of the Fund’s outstanding shares as described in “Description of Shares” below.

The Fund may not:

(1) Make loans, except to the extent permitted under the 1940 Act, the rules and regulations thereunder or any exemptions therefrom, as such statute, rules or regulations may be amended or interpreted from time to time.

(2) Purchase or sell real estate or real estate limited partnerships, except to the extent permitted under the 1940 Act, the rules and regulations thereunder or any exemptions therefrom, as such statute, rules or regulations may be amended or interpreted from time to time. This restriction shall not prevent the Fund from investing directly or indirectly in portfolio instruments secured by real estate or interests therein or acquiring securities of REITs or other issuers that deal in real estate.

(3) Invest in commodities or commodity contracts, except to the extent permitted under the 1940 Act, the rules and regulations thereunder or any exemptions therefrom, as such statute, rules or regulations may be amended or interpreted from time to time.

(4) Act as underwriter of securities, except to the extent permitted under the 1940 Act, the rules and regulations thereunder or any exemptions therefrom, as such statute, rules or regulations may be amended or interpreted from time to time.

(5) Concentrate its investments in a particular industry or group of industries, as concentration is defined under the 1940 Act, the rules and regulations thereunder or any exemption therefrom, as such statute, rules or regulations may be amended or interpreted from time to time.

(6) Borrow money or issue senior securities, except to the extent permitted under the 1940 Act, the rules and regulations thereunder or any exemptions therefrom, as such statute, rules or regulations may be amended or interpreted from time to time.

Notwithstanding any of a Fund’s other fundamental investment restrictions (including, without limitation, those restrictions relating to issuer diversification and industry concentration), the Fund may: (a) purchase securities of other investment companies to the full extent permitted under Section 12 of the 1940 Act or any other provision of the 1940 Act (or any successor provision thereto) or under any regulation or order of the SEC; and (b) invest all or substantially all of its assets in a single open-end investment company or series thereof with substantially the same investment objective, strategies and fundamental restrictions as the Fund.

The following descriptions may assist shareholders in understanding the requirements of the 1940 Act and interpretations thereunder in connection with the above policies and restrictions for the Fund. Certain investment restrictions set forth above may provide the Fund with the ability to operate under new interpretations of the 1940 Act or pursuant to exemptive relief from the SEC without receiving prior shareholder approval of the change.

40

The following descriptions are limited by any non-fundamental investment restrictions described above and are subject to the Fund’s investment objective and general investment strategies as stated in the Fund’s Prospectus and this SAI.

Concentration and Industry Classification. The SEC has presently defined concentration as investing more than 25% of an investment company’s net assets in an industry or group of industries, with certain exceptions.

Except to the extent otherwise provided in each of the Investment Restrictions above, for the purpose of determining industry classification, the Fund may use the industry classification provided by a third-party service provider. For the purpose of determining the percentage of the Fund’s total assets invested in securities of issuers having their principal business activities in a particular industry, (i) an asset-backed security will be classified separately based on the nature of its underlying assets; (ii) state and municipal governments and their agencies and authorities are not deemed to be industries; (iii) as to utility companies, the gas, electric, water and telephone businesses are considered separate industries; (iv) personal credit finance companies and business credit finance companies are deemed to be separate industries; and (v) wholly owned financial companies are considered to be in the industries of their parents if their activities are primarily related to financing the activities of their parents.

Borrowing. The 1940 Act presently allows a Fund to borrow from any bank (including pledging, mortgaging or hypothecating assets) in an amount up to 33-1/3% of its total assets, including the amount borrowed (not including temporary borrowings not in excess of 5% of its total assets).

Senior Securities. Senior securities may include any obligation or instrument issued by a Fund evidencing indebtedness. The 1940 Act generally prohibits Funds from issuing senior securities, except that the Fund may borrow money as described in the above policies and restrictions. Rule 18f-4 under the 1940 Act permits the Fund to enter into derivatives transactions and certain other transactions notwithstanding the restrictions on the issuance of “senior securities” under Section 18 of the 1940 Act so long as such transactions are entered into in compliance with Rule 18f-4 under the 1940 Act.

Lending. Under the 1940 Act, a Fund is required to have a fundamental investment policy governing making loans to other persons. Current SEC staff interpretations under the 1940 Act prohibit the Fund from lending more than 33-1/3% of its total assets, except through the lending of portfolio securities, the purchase of debt obligations or the use of repurchase agreements.

Diversification. Under the 1940 Act, a diversified fund may not, with respect to 75% of its total assets, purchase securities of an issuer (other than (i) obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities and (ii) securities of other investment companies) if, as a result, (a) more than 5% of the Fund’s total assets would be invested in securities of that issuer or (b) the Fund would hold more than 10% of the outstanding voting securities of that issuer.

Underwriting. Under the 1940 Act, underwriting securities involves a Fund purchasing securities directly from an issuer for the purpose of selling (distributing) them or participating in any such activity either directly or indirectly. Under the 1940 Act, a diversified Fund may not make any commitment as underwriter, if immediately thereafter the amount of its outstanding underwriting commitments, plus the value of its investments in securities of issuers (other than investment companies) of which it owns more than 10% of the outstanding voting securities, exceeds 25% of the value of its total assets.

Real Estate. The 1940 Act does not directly restrict a Fund’s ability to invest in real estate, but does require that the Fund have a fundamental investment policy governing such investments.

Securities held in escrow or separate accounts in connection with the Fund’s investment practices described in this SAI and the Prospectus are not deemed to be mortgaged, pledged or hypothecated for purposes of the foregoing restrictions.

41

Any Investment Restriction that involves a maximum percentage (other than the restriction set forth above with respect to borrowing money) will not be considered violated unless an excess over the percentage occurs immediately after, and is caused by, an acquisition of securities or assets of, or borrowings by the Fund. The 1940 Act requires the Fund to continuously maintain an “asset coverage” of at least 300% of the amount of its borrowings. If the asset coverage for borrowings at any time falls below 300% of the amount borrowed the Fund will, within three days thereafter (not including Sundays and holidays), reduce the amount of its borrowings to an extent that the net asset coverage of such borrowings shall conform to such limits.

CONTINUOUS OFFERING

The method by which Creation Unit Aggregations of shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Unit Aggregations of shares are issued and sold by the Fund on an ongoing basis, at any point a “distribution,” as such term is used in the Securities Act, may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the Securities Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Unit Aggregations after placing an order with the Transfer Agent, breaks them down into constituent shares, and sells such shares directly to customers, or if it chooses to couple the creation of a supply of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter. Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, generally are required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(3) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. Firms that incur a prospectus delivery obligation with respect to shares of the Fund are reminded that, pursuant to Rule 153 under the Securities Act, a prospectus delivery obligation under Section 5(b)(2) of the Securities Act owed to an exchange member in connection with a sale on the Listing Exchange is satisfied by the fact that the prospectus is available at the Listing Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is only available with respect to transactions on an exchange.

DISCLOSURE OF PORTFOLIO HOLDINGS

The Board has adopted a policy on disclosure of portfolio holdings, which it believes is in the best interest of the Fund’s shareholders. The policy provides that neither the Fund nor their Investment Adviser, Distributor or any agent, or any employee thereof (“Fund Representative”) will disclose the Fund’s portfolio holdings information to any person other than in accordance with the Trust’s policies and procedures. For purposes of the policy, “portfolio holdings information” means the Fund’s actual portfolio holdings, as well as non-public information about its trading strategies or pending transactions including the portfolio holdings, trading strategies or pending transactions of any commingled fund portfolio which contains identical holdings as the Fund. Under the policy, neither the Fund nor any Fund Representative may solicit or accept any compensation or other consideration in connection with the disclosure of portfolio holdings information. A Fund Representative may provide portfolio holdings information to third parties if such information has been included in the Fund’s public filings with the SEC or is disclosed on the Fund’s publicly accessible website. Information posted on the Fund’s website may be separately provided to any person commencing the day after it is first published on the Fund’s website.

Under the policy, the Fund’s portfolio holdings information will be provided by the Fund Administrator/Custodian to the National Securities Clearing Corporation (“NSCC”) each business day for dissemination through the NSCC’s facilities and/or other fee-based subscription services to NSCC members and/or subscribers

42

to those other fee-based subscription services, including Authorized Participants, which are generally large institutional investors that have been authorized by the Fund’s distributor to purchase and redeem from the Fund, and to entities that publish and/or analyze such information in connection with the process of purchasing or redeeming Creation Units or trading shares of the Fund in the secondary market. The Fund discloses its portfolio holdings and the percentages they represent of the Fund’s net assets on the Fund’s website prior to the opening of regular trading on the primary listing exchange of the Fund’s shares each day the Fund is open for business. The Distributor may also make available portfolio holdings information to other institutional market participants and entities that provide information services. This information typically reflects the Fund’s anticipated holdings on the following business day. Certain NTI employees discuss custom basket proposals with Authorized Participants and market makers as described under “Custom Baskets” in the “Purchase and Redemption of Creation Unit Aggregations” section of this SAI. As part of these custom basket discussions, these NTI employees may discuss the securities the Fund is willing to accept for a creation order, and securities that the Fund will provide for a redemption order. NTI employees may also discuss the Fund’s portfolio holdings-related information with broker-dealers, in connection with settling the Fund’s transactions, as may be necessary to conduct business in the ordinary course and in a manner consistent with the Trust’s policies and procedures.

Portfolio holdings will be disclosed through required filings with the SEC. The Fund files its portfolio holdings with the SEC and the holdings are publicly made available twice each fiscal year on Form N-CSR (with respect to each annual period and semiannual period) and twice each fiscal year on Form N-PORT (with respect to the first and third fiscal quarters of the Fund’s fiscal year). Shareholders may obtain the Fund’s Forms N-CSR and N-PORT filings on the SEC’s website at sec.gov. You may call the SEC at 1-800-SEC-0330 for information about the SEC’s website.

Under the Trust’s policies and procedures, the Board is to receive information, on a quarterly basis, regarding any other disclosures of non-public portfolio holdings information that were permitted during the preceding quarter.
