Fund shares are anticipated to be available to the public on or about [________, 2022].

This prospectus provides important information about Columbia Seligman Semiconductor Technology ETF (the Fund), an exchange-traded fund (ETF) that is a series of Columbia ETF Trust I (the Trust), that you should know before investing. Please read it carefully and keep it for future reference.

This ETF is different from traditional ETFs.

Traditional ETFs tell the public what assets they hold each day. This ETF will not. This may create additional risks for your investment. For example:

■	You may have to pay more money to trade this ETF’s shares. This ETF will provide less information to traders, who tend to charge more for trades when they have less information.
■	The price you pay to buy this ETF shares on an exchange may not match the value of the ETF’s portfolio. The same is true when you sell shares. These price differences may be greater for this ETF compared to other ETFs because it provides less information to traders.
■	These additional risks may be even greater in bad or uncertain market conditions.
■	This ETF will publish on its website each business day a “Tracking Basket” designed to help trading in shares of the ETF. While the Tracking Basket includes some of the ETF’s holdings, it is not the ETF’s actual portfolio.

The differences between this ETF and other ETFs may also have advantages. By keeping certain information about this ETF secret, this ETF may face less risk that other traders can predict or copy its investment strategy. This may improve the ETF’s performance. If other traders are able to copy or predict the ETF’s investment strategy, however, this may hurt the ETF’s performance.

For additional information regarding the unique attributes and risks of this ETF, see the section entitled “Principal Risks” in the Summary Prospectus and the Prospectus, and the sections “How the Fund Differs from Traditional Mutual Funds” and “How the Fund Differs from ETFs that Disclose their Portfolio Holdings Daily” in the Prospectus.

These securities have not been approved or disapproved by the Securities and Exchange Commission (SEC), nor has the SEC passed upon the adequacy of this prospectus. Any representation to the contrary is a criminal offense.

Shares of the Fund are listed and traded on [________].

No person has been authorized to give any information or to make any representations other than those contained in this prospectus and the Fund's Statement of Additional Information (SAI) dated [______], 2022 (which is incorporated by reference into this prospectus and is legally a part of this prospectus) and, if given or made, such information or representations may not be relied upon as having been authorized by us.

Summary of the Fund

Investment Objective

Columbia Seligman Semiconductor Technology ETF (the Fund) seeks capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions, to financial intermediaries, which are not reflected in the table and example below. If such expenses were reflected, the expenses set forth below would be higher.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management fees^(a)	[_____]%
Distribution and/or service (12b-1) fees	[_____]%
Other expenses	[_____]%
Total annual Fund operating expenses	[_____]%

(a)

Pursuant to the Investment Management Services Agreement with Columbia ETF Trust I on behalf of the Fund, Columbia Management Investment Advisers, LLC pays the operating costs and expenses of the Fund, but not taxes, interest, brokerage expenses, portfolio transaction expenses, and infrequent and/or unusual expenses.

Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example illustrates the hypothetical expenses that you would incur over the time periods indicated (whether or not shares are redeemed), and assumes that:

■	you invest $10,000 in the Fund for the periods indicated,
■	your investment has a 5% return each year, and
■	the Fund’s total annual operating expenses remain the same as shown in the Annual Fund Operating Expenses table above.

The example also does not include transaction fees on purchases and redemptions of Creation Units (defined below) because those fees will not be imposed on retail investors. Although your actual costs may be higher or lower, based on the assumptions listed above, your costs (based on estimated Fund expenses) would be:

	1 year	3 years
	$[_____]	$[_____]

Portfolio Turnover

The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. Because the Fund is newly organized, portfolio turnover information is not available as of the date of this prospectus.

Summary of the Fund (continued)

Principal Investment Strategies

The Fund is an actively managed exchange-traded fund (ETF) that operates pursuant to an exemptive order from the Securities and Exchange Commission (the Order) and is not required to publicly disclose its complete portfolio holdings each business day. Additional information about this appears below.

Under normal market conditions, the Fund invests at least 80% of its net assets (including the amount of any borrowings for investment purposes) in securities of semiconductor, semiconductor equipment and related companies. The companies that the Fund invests in may be engaged in the design, manufacturing process, distribution or sale of semiconductors, other integrated chips, semiconductor equipment and related products and services. These companies will generally operate in the semiconductors and semiconductor equipment, communication equipment, electronic equipment, instruments and components, technology hardware, storage and peripherals, and software industries.

The Fund may invest in securities of companies of any size, including small- and mid-capitalization companies. The Fund typically employs a focused portfolio investing style, generally holding between 30 and 50 securities. However, the Fund may at any time hold less or more securities than the range noted. The Fund is non-diversified, which means that it can invest a greater percentage of its assets in the securities of fewer issuers than can a diversified fund. The Fund will generally invest in common stocks that can be expected to grow with the market (i.e., growth stocks). The Fund may invest in or have investment exposure to foreign companies.

The Fund is an actively managed ETF that operates pursuant to the Order and is not required to publicly disclose its complete portfolio holdings each business day. Instead, the Fund publishes each business day on its website a “Tracking Basket,” which is designed to closely track the daily performance of the Fund but is not the Fund’s actual portfolio. The Tracking Basket is comprised of: select recently disclosed portfolio holdings (Strategy Components); liquid ETFs that convey information about the types of instruments (that are not otherwise fully represented by the Strategy Components) in which the Fund invests (Representative ETFs); and cash and cash equivalents. The Tracking Basket often may include a significant percentage of the securities held in the Fund’s portfolio, but it will exclude (or modify the weightings of) certain securities held in the Fund’s portfolio, such as those securities that the Fund’s portfolio managers are actively looking to purchase or sell, or securities which, if disclosed, could increase the risk of front-running or free-riding. For additional information regarding the Tracking Basket, see the section “How the Fund Differs from ETFs that Disclose their Portfolio Holdings Daily” in the Prospectus.

The Fund also publishes each business day on its website the “Tracking Basket Weight Overlap,” which is the percentage weight overlap between the holdings of the prior business day’s Tracking Basket compared to the holdings of the Fund that formed the basis for the Fund’s calculation of net asset value per share (NAV) at the end of the prior business day. The Tracking Basket Weight Overlap is designed to provide investors with an understanding of how similar the Tracking Basket is to the Fund’s actual portfolio in percentage terms.

Principal Risks

An investment in the Fund involves risks, including Tracking Basket Structure Risk, Semiconductors and Semiconductor Equipment Industry Risk, Active Management Risk, Focused Portfolio Risk, and New Fund Risk, among others. Descriptions of these and other principal risks of investing in the Fund are provided below. There is no assurance that the Fund will achieve its investment objective and you may lose money. The value of the Fund’s holdings may decline, and the Fund’s net asset value (NAV) and share price may go down. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Active Management Risk. The Fund is actively managed and its performance therefore will reflect, in part, the ability of the portfolio managers to make investment decisions that seek to achieve the Fund’s investment objective. The Fund is not an index fund (it does not seek to track the performance of an index), nor does it provide daily transparency into its portfolio holdings like most other ETFs. Due to its active management, the Fund could underperform its benchmark index and/or other funds with similar investment objectives and/or strategies. Active trading of portfolio securities may result in added expenses, a lower return and increased tax liability, including relative to other ETFs, particularly passive ETFs, but other active ETFs as well.

Columbia Seligman Semiconductor Technology ETF

Summary of the Fund (continued)

Arbitrage Risk. Unlike ETFs that publicly disclose their complete portfolio holdings daily, the Fund discloses each business day the Tracking Basket and Tracking Basket Weight Overlap, which are intended to allow market participants to estimate the value of positions in the Fund’s shares. Although this information is designed to facilitate arbitrage opportunities in Fund shares to reduce bid/ask spreads and minimize discounts or premiums between the market price and the NAV of the Fund’s shares, there is no guarantee the Fund’s arbitrage mechanism will operate as intended and that the Fund will not experience wide bid/ask spreads and/or large discounts or premiums to NAV.

Authorized Participant Concentration Risk. Only an Authorized Participant (as defined below) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants, none of which are or will be obligated to engage in creation or redemption transactions. To the extent that these institutions exit the business or are unable or unwilling to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able or willing to step forward to create or redeem Creation Units, Fund shares may trade at a discount to NAV and possibly face trading halts and/or delisting from the Exchange. This risk may be heightened due to the fact that the Fund does not disclose its complete portfolio holdings daily, unlike passive ETFs and certain other actively managed ETFs, and could be greater in times of market stress, including at both the Fund share level and at the Fund holdings level.

Early Close/Late Close/Trading Halt Risk. An exchange or market may close early, close late or issue trading halts on specific securities, or the ability to buy or sell certain securities may be restricted, which may result in the Fund being unable to buy or sell these securities. There may be circumstances where a security held in the Fund’s portfolio but not in the Tracking Basket does not have readily available market quotations. If the Investment Manager determines that such circumstance may affect the reliability of the Tracking Basket as an arbitrage vehicle, that information, along with the identity and weighting of that security in the Fund’s portfolio, will be publicly disclosed on the Fund’s website and the Investment Manager will assess appropriate remedial measures. In these circumstances, market participants may use this information to engage in certain predatory trading practices that may have the potential to harm the Fund and its shareholders. If securities representing 10% or more of the Fund’s portfolio do not have readily available market quotations, the Investment Manager will promptly request the Exchange to halt trading on the Fund, meaning that investors would not be able to trade Fund shares.

Focused Portfolio Risk. Because the Fund may invest in a limited number of companies, the Fund as a whole is subject to greater risk of loss if any of those securities decline in price.

Foreign Securities Risk. Investments in or exposure to foreign companies involve certain risks not associated with investments in or exposure to securities of U.S. companies. Investing in foreign companies subjects the Fund to the risks associated with issuer’s (and any of its related companies’) country of organization and places of business operations and exposures, including political, regulatory, economic, social, diplomatic and other conditions or events (including, for example, military confrontations, war, terrorism and disease/virus outbreaks and epidemics), occurring in the country or region, as well as risks associated with less developed custody and settlement practices. Foreign securities may be more volatile and less liquid than securities of U.S. companies, and are subject to the risks associated with potential imposition of economic and other sanctions against a particular foreign country, its nationals or industries or businesses within the country. In addition, foreign governments may impose withholding or other taxes on the Fund’s income, capital gains or proceeds from the disposition of foreign securities, which could reduce the Fund’s return on such securities.

Fund Shares Liquidity Risk. Although the Fund’s shares are listed on the Exchange, there can be no assurance that an active, liquid or otherwise orderly trading market for shares will be established or maintained by market makers or Authorized Participants, particularly in times of stressed market conditions. There is no guarantee that the Fund will be able to attract market makers and Authorized Participants. There is no obligation for market makers to make a market in the Fund’s shares or for Authorized Participants to submit purchase or redemption orders for creation units. Accordingly, if such parties determine not to perform their respective functions, this could, in turn, lead to variances between the market price of the Fund’s shares and the underlying value of those shares. Trading in Fund shares on the Exchange also may be disrupted or even halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund shares inadvisable. In addition, trading in Fund shares on the Exchange

Prospectus 2022

Table of Contents

Columbia Seligman Semiconductor Technology ETF

Summary of the Fund (continued)

may be subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There also can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund’s shares will continue to be met or will remain unchanged.

Growth Securities Risk. Growth securities typically trade at a higher multiple of earnings than other types of equity securities. Accordingly, the market values of growth securities may never reach their expected market value and may decline in price. In addition, growth securities, at times, may not perform as well as value securities or the stock market in general, and may be out of favor with investors for varying periods of time.

Issuer Risk. An issuer in which the Fund invests or to which it has exposure may perform poorly or below expectations, and the value of its securities may therefore decline, which may negatively affect the Fund’s performance. Underperformance of an issuer may be caused by poor management decisions, competitive pressures, breakthroughs in technology, reliance on suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, natural disasters, military confrontations, war, terrorism, disease/virus outbreaks, epidemics or other events, conditions and factors which may impair the value of an investment in the Fund and could result in increased premiums or discounts to the Fund’s net asset value.

■

Small- and Mid-Cap Stock Risk. Investments in small- and mid-capitalization companies (small- and mid-cap companies) often involve greater risks than investments in larger, more established companies (larger companies) because small- and mid-cap companies tend to have less predictable earnings and may lack the management experience, financial resources, product diversification and competitive strengths of larger companies. Securities of small- and mid-cap companies may be less liquid and more volatile than the securities of larger companies.

■

Large-Cap Stock Risk. Investments in larger companies may involve certain risks associated with their larger size. For instance, larger companies may be less able to respond quickly to new competitive challenges, such as changes in consumer tastes or innovation from smaller competitors. Also, larger companies are sometimes less able to achieve as high growth rates as successful smaller companies, especially during extended periods of economic expansion.

Market Price Relative to NAV Risk. Shares of the Fund may trade at prices that vary from Fund NAV. Shares of the Fund are listed for trading on the Exchange and are bought and sold in the secondary market at market prices that may differ, in some cases significantly, from their NAV. The NAV of the Fund will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of shares, however, will generally fluctuate in response to changes in NAV, as well as the relative supply of, and demand for, Fund shares on the Exchange. Fund shares may trade at a larger premium or discount to the NAV than shares of other ETFs, including ETFs that make their full portfolio holdings public on a daily or otherwise more frequent basis than the Fund. The Investment Manager cannot predict whether Fund shares will trade below, at or above their NAV. Price differences may result because of, among other factors, supply and demand forces in the secondary trading market for Fund shares. It is expected that these forces generally will be closely related to, but not identical to, the same forces influencing the prices of the Fund’s holdings. In this regard, if a shareholder purchases Fund shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses. Different investment strategies or techniques, including those intended to be defensive in nature, including, as examples, stop loss orders to sell an ETF’s shares in the secondary market during negative market events or conditions, such as a “flash crash” or other market disruptions may not work as intended and may produce significant losses to investors. Investors should consult their financial intermediary prior to using any such investment strategies or techniques, or before investing in the Fund.

Summary of the Fund (continued)

magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions and could result in increased premiums or discounts to the Fund’s net asset value.

The coronavirus disease 2019 and its variants (COVID-19) pandemic has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in less developed countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objective. Any such events could have a significant adverse impact on the value and risk profile of the Fund.

New Fund Risk. The Fund is a newly formed ETF that operates differently from ETFs that publish their full portfolio holdings daily. There can be no assurance that an active trading market will develop or be maintained or that the market for Fund shares will operate as intended, which could lead to the Fund’s shares trading at wider spreads and larger premiums and discounts to NAV than other ETFs that publish their portfolio holdings on a daily basis, particularly during periods of market disruption or volatility. As a result, it may cost investors more to trade Fund shares than shares of other ETFs. There is no guarantee that the Fund will be able to attract market makers and Authorized Participants. Market makers and Authorized Participants are not obligated to make a market in the Fund’s shares or to submit purchase and redemption orders for creation units. Accordingly, investors in the Fund bear the risk that the Fund may not be successful, which could result in the Fund being liquidated at any time without shareholder approval and/or at a time that may not be favorable to shareholders. Such a liquidation could have negative tax consequences for shareholders.

Non-Diversified Fund Risk. The Fund is non-diversified, which generally means that it will invest a greater percentage of its total assets in the securities of fewer issuers than a “diversified” fund. This increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, the Fund's value will likely be more volatile than the value of a more diversified fund.

Secondary Market Trading Risk. Investors buying or selling Fund shares will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund shares. The Fund has no public trading history and may operate differently from ETFs that publish their complete portfolio holdings on a daily basis, which could lead to the Fund shares trading at wider bid/ask spreads and larger premiums and discounts to NAV (particularly during periods of market disruption or volatility) than such other ETFs. As a result, it may cost investors more to trade Fund shares than shares of other ETFs.

Semiconductors and Semiconductor Equipment Industry Risk. The Fund will have a significant portion of its assets invested in securities of companies conducting business within the semiconductors and semiconductor equipment industry, which is included within the Information Technology sector. Companies in the same or related industries may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments than funds that invest more broadly. Generally, the more broadly a fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility. The Fund will be sensitive to,

Prospectus 2022

Table of Contents

Columbia Seligman Semiconductor Technology ETF

Summary of the Fund (continued)

and its performance may depend to a greater extent on, the overall condition of the semiconductor and semiconductor equipment industry. The risks of investments in the industry include: intense competition, both domestically and internationally, including competition from subsidized foreign competitors with lower production costs; wide fluctuations in securities prices due to risks of rapid obsolescence of products and related technology; economic performance of the customers of semiconductor and related companies; their research costs and the risks that their products may not prove commercially successful; and thin capitalization and limited product lines, markets, financial resources or quality management and personnel. These companies rely on a combination of patents, trade secret laws and contractual provisions to protect their technologies. The industry is characterized by frequent litigation regarding patent and other intellectual property rights, which may require such companies to defend against competitors’ assertions of intellectual property infringement or misappropriation. The international operations of many companies expose them to the risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, tariffs, and trade disputes. Business conditions in this industry can change rapidly from periods of strong demand to periods of weak demand. Any future downturn in the industry could harm the business and operating results of these companies. The stock prices of companies in the industry have been and will likely continue to be volatile relative to the overall market.

Tracking Basket Structure Risk. The Fund’s Tracking Basket structure may affect the price at which the Fund shares trade in the secondary market. Although the Tracking Basket is intended to provide investors with enough information to allow for an effective arbitrage mechanism that will keep the market price of the Fund at or close to the Fund’s NAV per share, there is a risk that market prices will vary significantly from NAV. ETFs trading on the basis of a published Tracking Basket may trade at a wider bid/ask spread than ETFs that publish their portfolio holdings on a daily basis and therefore, may cost investors more to trade. These risks may increase during periods of market disruption or volatility. In addition, although the Fund seeks to benefit from not disclosing portfolio holdings daily, market participants may attempt to use the Tracking Basket to identify the Fund’s trading strategy. If successful, this could result in such market participants engaging in certain predatory trading practices that may have the potential to harm the Fund and its shareholders, such as front-running (trading ahead) or free-riding (mirroring) the Fund’s strategy.

Purchase and Sale of Fund Shares

The Fund issues and redeems shares only through Authorized Participants (typically broker-dealers) in large blocks of shares, typically [_____] shares, called Creation Units. Creation Units are issued and redeemed generally in-kind in exchange for the deposit or delivery of the securities and cash included in the Fund's Tracking Basket. However, the Fund also reserves the right to permit or require Creation Units to be issued in exchange entirely or in part for cash. As a general matter, the Fund expects to receive cash (or, cash in lieu of) for Representative ETFs held in the Tracking Basket. Except when aggregated in Creation Units, the Fund shares are not redeemable securities of the Fund.

Individual shares may only be purchased and sold on secondary markets through a financial intermediary, such as a broker-dealer or a bank. Because the Fund’s shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). You may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the ETF (bid) and the lowest price a seller is willing to accept for shares of the ETF (ask) when buying or selling shares in the secondary market (“the bid/ask spread”). Recent information, including information regarding the Fund’s NAV, market price, premiums and discounts, and bid/ask spread, is available at columbiathreadneedleus.com/etfs.

Tax Information

Distributions you receive from the Fund are taxed as ordinary income for federal income tax purposes, except to the extent designated as net capital gain, qualified dividend or return of capital and may also be subject to state or local taxes, unless you are investing through a tax-advantaged retirement plan account or are a tax-exempt investor.

Payments to Broker-Dealers and Other Financial Intermediaries

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

More Information About the Fund

Investment Objective

Columbia Seligman Semiconductor Technology ETF (the Fund) seeks capital appreciation. The Fund’s investment objective is not a fundamental policy and may be changed by the Fund’s Board of Trustees without shareholder approval. Because any investment involves risk, there is no assurance the Fund’s investment objective will be achieved.

Principal Investment Strategies

The Fund uses a bottom-up stock selection approach. This means that Columbia Management Investment Advisers, LLC (the Investment Manager) uses extensive in-depth research into specific companies to find those companies that it believes offer significant prospects for future growth. In selecting individual securities, the Investment Manager generally looks for companies that it believes display or are expected to display:

■	Growth prospects;
■	High profit margins or return on capital;
■	Attractive valuation relative to expected earnings or cash flow;
■	Quality management; and/or

10	Prospectus 2022

■	Unique competitive advantages.

The Fund generally sells a stock if the Investment Manager believes:

■	its target price is reached;

■	its valuation becomes excessive;

■	its earnings or revenue growth are disappointing;

■	its underlying fundamentals have deteriorated; and/or

■	more attractive investment opportunities are believed to be available.

The Fund’s investment policy with respect to 80% of its assets may be changed by the Fund’s Board of Trustees without shareholder approval as long as shareholders are given 60 days’ advance written notice of the change.

Principal Risks

the Fund’s website and the Investment Manager will assess appropriate remedial measures. In these circumstances, market participants may use this information to engage in certain predatory trading practices that may have the potential to harm the Fund and its shareholders. If securities representing 10% or more of the Fund’s portfolio do not have readily available market quotations, the Investment Manager will promptly request the Exchange to halt trading on the Fund, meaning that investors would not be able to trade Fund shares.

Focused Portfolio Risk. The Fund, because it may invest in a limited number of companies, may have more volatility in its NAV and is considered to have more risk than a fund that invests in a greater number of companies because changes in the value of a single security may have a more significant effect, either negative or positive, on the Fund’s NAV. To the extent the Fund invests its assets in fewer securities, the Fund is subject to greater risk of loss if any of those securities decline in price.

Foreign Securities Risk. Investments in or exposure to foreign companies involve certain risks not associated with investments in or exposure to securities of U.S. companies. For example, foreign markets can be extremely volatile. Foreign securities may also be less liquid, making them more difficult to trade, than securities of U.S. companies so that the Fund may, at times, be unable to sell foreign securities at desirable times or prices. Brokerage commissions, custodial costs and other fees are also generally higher for foreign securities. The Fund may have limited or no legal recourse in the event of default with respect to certain foreign securities, including those issued by foreign governments. In addition, foreign governments may impose withholding or other taxes on the Fund’s income, capital gains or proceeds from the disposition of foreign securities, which could reduce the Fund’s return on such securities. In some cases, such withholding or other taxes could potentially be confiscatory. Other risks include: possible delays in the settlement of transactions or in the payment of income; generally less publicly available information about foreign companies; the impact of economic, political, social, diplomatic or other conditions or events (including, for example, military confrontations, war, terrorism and disease/virus outbreaks and epidemics), possible seizure, expropriation or nationalization of a company or its assets or the assets of a particular investor or category of investors; accounting, auditing and financial reporting standards that may be less comprehensive and stringent than those applicable to domestic companies; the imposition of economic and other sanctions against a particular foreign country, its nationals or industries or businesses within the country; and the generally less stringent standard of care to which local agents may be held in the local markets. In addition, it may be difficult to obtain reliable information about the securities and business operations of certain foreign issuers. Governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. The less developed a country’s securities market is, the greater the level of risks. Economic sanctions may be, and have been, imposed against certain countries, organizations, companies, entities and/or individuals. Economic sanctions and other similar governmental actions could, among other things, effectively restrict or eliminate the Fund’s ability to purchase or sell securities, and thus may make the Fund’s investments in such securities less liquid or more difficult to value. In addition, as a result of economic sanctions, the Fund may be forced to sell or otherwise dispose of investments at inopportune times or prices, which could result in losses to the Fund and increased transaction costs. These conditions may be in place for a substantial period of time and enacted with limited advance notice to the Fund. The risks posed by sanctions against a particular foreign country, its nationals or industries or businesses within the country may be heightened to the extent the Fund invests significantly in the affected country or region or in issuers from the affected country that depend on global markets. Additionally, investments in certain countries may subject the Fund to a number of tax rules, the application of which may be uncertain. Countries may amend or revise their existing tax laws, regulations and/or procedures in the future, possibly with retroactive effect. Changes in or uncertainties regarding the laws, regulations or procedures of a country could reduce the after-tax profits of the Fund, directly or indirectly, including by reducing the after-tax profits of companies located in such countries in which the Fund invests, or result in unexpected tax liabilities for the Fund. Currency rates in foreign countries may fluctuate significantly over short or long periods of time for a number of reasons, including changes in interest rates, imposition of currency exchange controls and economic or political developments in the U.S. or abroad. The Fund may also incur currency conversion costs when converting foreign currencies into U.S. dollars and vice versa.

be able to attract market makers and Authorized Participants. There is no obligation for market makers to make a market in the Fund’s shares or for Authorized Participants to submit purchase or redemption orders for creation units. Accordingly, if such parties determine not to perform their respective functions, this could, in turn, lead to variances between the market price of the Fund’s shares and the underlying value of those shares. Trading in Fund shares on the Exchange also may be disrupted or even halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund shares inadvisable. In addition, trading in Fund shares on the Exchange may be subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There also can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund’s shares will continue to be met or will remain unchanged.

Small- and Mid-Cap Stock Risk. Securities of small- and mid-cap companies can, in certain circumstances, have a higher potential for gains than securities of larger companies but are more likely to have more risk than larger companies. For example, small- and mid-cap companies may be more vulnerable to market downturns and adverse business or economic events than larger companies because they may have more limited financial resources and business operations. Small- and mid-cap companies are also more likely than larger companies to have more limited product lines and operating histories and to depend on smaller and generally less experienced management teams. Securities of small- and mid-cap companies may trade less frequently and in smaller volumes and may be less liquid and fluctuate more sharply in value than securities of larger companies. When the Fund takes significant positions in small- and mid-cap companies with limited trading volumes, the liquidation of those positions, particularly in a distressed market, could be prolonged and result in Fund investment losses that would affect the value of your investment in the Fund. In addition, some small- and mid-cap companies may not be widely followed by the investment community, which can lower the demand for their stocks.

as examples, stop loss orders to sell an ETF’s shares in the secondary market during negative market events or conditions, such as a “flash crash” or other market disruptions may not work as intended and may produce significant losses to investors. Investors should consult their financial intermediary prior to using any such investment strategies or techniques, or before investing in the Fund.

Market Risk. The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions and could result in increased premiums or discounts to the Fund’s net asset value.

More Information About the Fund (continued)

The Fund will be sensitive to, and its performance may depend to a greater extent on, the overall condition of the semiconductor and semiconductor equipment industry. The risks of investments in the industry include: intense competition, both domestically and internationally, including competition from subsidized foreign competitors with lower production costs; wide fluctuations in securities prices due to risks of rapid obsolescence of products and related technology; economic performance of the customers of semiconductor and related companies; their research costs and the risks that their products may not prove commercially successful; and thin capitalization and limited product lines, markets, financial resources or quality management and personnel. Semiconductor design and process methodologies are subject to rapid technological change requiring large expenditures, potentially requiring financing that may be difficult or impossible to obtain, for research and development in order to improve product performance and increase manufacturing yields. These companies rely on a combination of patents, trade secret laws and contractual provisions to protect their technologies. The process of seeking patent protection can be long and expensive. The industry is characterized by frequent litigation regarding patent and other intellectual property rights, which may require such companies to defend against competitors’ assertions of intellectual property infringement or misappropriation. Some companies are also engaged in other lines of business unrelated to the semiconductor business, and these companies may experience problems with these lines of business that could adversely affect their operating results. The international operations of many companies expose them to the risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, tariffs, and trade disputes. Business conditions in this industry can change rapidly from periods of strong demand to periods of weak demand. Any future downturn in the industry could harm the business and operating results of these companies. The stock prices of companies in the industry have been and will likely continue to be volatile relative to the overall market.

The industry may also be affected by risks that affect the broader technology sector, including: government regulation, dramatic and often unpredictable changes in growth rates and competition for qualified personnel, a small number of companies representing a large portion of the technology semiconductor industry as a whole, cyclical market patterns, significant product price erosion hampering company profits, periods of over-capacity and production shortages, changing demand, variations in manufacturing costs and yields and significant expenditures for capital equipment and product development.

market participants may attempt to use the Tracking Basket to identify the Fund’s trading strategy. If successful, this could result in such market participants engaging in certain predatory trading practices that may have the potential to harm the Fund and its shareholders, such as front-running (trading ahead) or free-riding (mirroring) the Fund’s strategy.

How the Fund Differs from Traditional Mutual Funds

Redeemability. Traditional mutual fund shares may be bought from, and redeemed with, the issuing fund for cash at NAV typically calculated once at the end of each business day. Shares of an ETF, by contrast, cannot be purchased from or redeemed with the ETF except by or through Authorized Participants (defined below), and then generally in-kind in exchange for the deposit or delivery of the securities and cash included in the Fund's Tracking Basket. However, the Fund also reserves the right to permit or require Creation Units to be issued in exchange entirely or in part for cash. As a general matter, the Fund expects to receive cash (or, cash in lieu of) for Representative ETFs held in the Tracking Basket. Except when aggregated in Creation Units, the Fund shares are not redeemable securities of the Fund. In addition, ETFs issue and redeem shares on a continuous basis only in large blocks of shares, typically [_____] shares (which is the case for the Fund), called Creation Units.

The Fund may delay payment of redemption proceeds for its securities for up to 15 calendar days, based in part on the greater relative illiquidity and longer settlement times of emerging market securities. This risk applies to those who purchase and sell Creation Units directly from and to the Fund and does not apply to investors who will buy and sell shares of the Fund in secondary market transactions on the Exchange through brokers.

Exchange Listing. Unlike traditional mutual fund shares, the Fund’s shares are listed for trading on the Exchange. Investors can purchase and sell shares on the secondary market through a broker or other financial intermediary (collectively, financial intermediary(ies)). There can be no assurance that the Fund's shares will continue to trade on the Exchange or that the Fund's shares will continue to meet the requirements for listing or trading on the Exchange. Investors purchasing shares in the secondary market through a brokerage account or with the assistance of a financial intermediary may be subject to brokerage commissions and charges. Secondary-market transactions do not occur at NAV, but at market prices that change throughout the day, based on the supply of, and demand for, shares and on changes in the prices of the Fund’s portfolio holdings. The market price of shares may differ from the NAV of the Fund. The difference between market price of shares and the NAV of the Fund is called a premium when the market price is above the reported NAV and called a discount when the market price is below the reported NAV. The market price of the Fund's shares may deviate significantly from the NAV of the shares, for example, in times of extreme market volatility or other conditions.

Tax Treatment. The Fund’s structure may provide for enhanced tax efficiency relative to a traditional mutual fund’s structure. Specifically, to the extent the Fund redeems its shares in kind, the distribution of portfolio securities to meet such redemption requests may mitigate certain adverse tax consequences associated with traditional mutual fund shares to continuing Fund shareholders. This is because traditional mutual funds typically sell portfolio securities to obtain cash to meet redemptions and, as necessary, may recognize taxable gains in connection with such sales. By contrast, to the extent the Fund redeems its shares in kind, as opposed to in cash, the Fund’s in-kind redemption mechanism will potentially reduce, relative to a traditional mutual fund, taxable gains resulting from redemptions. However, the Fund cannot predict to what extent, if any, it will redeem its shares in kind rather than in cash, particularly during the Fund’s growth stages when portfolio changes are more likely to be implemented within the Fund rather than through the in-kind redemption mechanism. Nor can the Fund predict the extent to which any such in-kind redemptions will reduce the taxable gain recognized in connection therewith.

ETFs generally are able to make in-kind redemptions and avoid being taxed on gain on the distributed portfolio securities at the Fund level. Because the Fund may effect redemptions partly or entirely in cash, rather than in-kind distributions, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. If the Fund recognizes gain on these sales, this generally will cause the Fund to recognize gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities in-kind. The Fund generally intends to distribute these gains to shareholders to avoid being taxed on this gain at the Fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier

date than, if they had made an investment in a different ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares principally in-kind, will be passed on to purchasers and redeemers of Creation Units in the form of creation and redemption transaction fees.

How the Fund Differs from ETFs that Disclose their Portfolio Holdings Daily

The Fund is an actively managed ETF that operates pursuant to the Order. Like other ETFs, shares of the Fund are generally purchased and redeemed in creation unit aggregations through authorized participants, shares of the Fund are listed and traded on a stock exchange, and individual investors can purchase or sell shares in less than creation unit sizes and for cash in the secondary market through a financial intermediary, such as a broker. The Fund’s creation units generally can be purchased or redeemed in-kind in exchange for the Strategy Components included in the Fund’s Tracking Basket, together with an amount of cash corresponding to the value of the Representative ETFs and cash and cash equivalents that form the remainder of the Tracking Basket.

Tracking Basket Structure. However, the Fund has some unique features that differentiate it from other ETFs. As described above, the Fund does not disclose its complete portfolio holdings each business day, and instead, the Fund discloses other information to the market that is designed to facilitate arbitrage opportunities in Fund shares to maintain efficient secondary market trading of shares. On each business day before the commencement of trading in shares on the Exchange, the Fund publishes on its website a Tracking Basket that is designed to closely track the daily performance of the Fund. The Tracking Basket is comprised of Strategy Components (select recently disclosed portfolio holdings), Representative ETFs (liquid ETFs that convey information about the types of instruments (that are not otherwise fully represented by the Strategy Components) in which the Fund invests), and cash and cash equivalents. Representative ETFs are selected for inclusion in the Tracking Basket such that, when aggregated with the other Tracking Basket components, the Tracking Basket corresponds to the Fund’s overall holdings exposure. Representative ETFs may constitute no more than 50% of the Tracking Basket’s assets on each business day at the time that the Tracking Basket is published. The Tracking Basket is constructed utilizing an optimization process to minimize daily deviations in return of the Tracking Basket relative to the Fund and is used to facilitate the creation/redemption process and arbitrage. The Tracking Basket is typically expected to be rebalanced on schedule with the public disclosure of the Fund’s holdings; however, a new Tracking Basket may be generated as frequently as daily. In determining whether to rebalance the Tracking Basket, the Investment Manager will consider various factors, including liquidity of the securities in the Tracking Basket, tracking error of the Tracking Basket relative to the Fund, and the cost to create and trade the Tracking Basket.

Tracking Basket Weight Overlap. In addition to disclosure of the Tracking Basket, the Fund publishes the “Tracking Basket Weight Overlap” on its website on each business day before the commencement of trading in Fund shares on the Exchange. The Tracking Basket Weight Overlap is the percentage weight overlap between the holdings of the prior day’s Tracking Basket compared to the holdings of the Fund that formed the basis for the Fund’s calculation of NAV at the end of the prior business day. It is calculated by taking the lesser weight of each asset held in common between the Fund’s portfolio and the Tracking Basket, and adding the totals. The Tracking Basket Weight Overlap is intended to provide investors with an understanding of the degree to which the Tracking Basket and the Fund’s portfolio overlap and help investors evaluate the risk that the performance of the Tracking Basket may deviate from the performance of the portfolio holdings of the Fund.

Information Available at Fund Website and Fund Portfolio Holdings Disclosure

Additionally, each business day before the commencement of trading Fund shares, the Fund will publish on the Fund’s website further information, including: the

Tracking Basket, the Tracking Basket Weight Overlap, the prior business day’s NAV and the closing price or bid/ask price, a calculation of the premium or discount of the prior business day's closing price or bid/ask price against the prior business day's NAV. The Fund also discloses on its website its full portfolio holdings, including the name, identifier, market value and weight of each security and instrument in the portfolio, as of month-end approximately, but no earlier than, [__] calendar days after such month-end.

In addition, the Tracking Basket, which identifies the securities (cash in lieu of Representative ETFs, as described above) which may be delivered in exchange for purchases and redemptions of Creation Units, are publicly disseminated each business day prior to the opening of trading on the Exchange via the National Securities Clearing Corporation (NSCC).

Permitted Instrument Types and Other Fund Policies

This section describes certain investment strategies and policies that the Fund may utilize in pursuit of its investment objective and some additional factors and risks involved with investing in the Fund.

Under the terms of the Order, the Fund’s investments are limited to the following: ETFs, notes, common stocks, preferred stocks, American Depositary Receipts (ADRs), real estate investment trusts (REITs), commodity pools, metals trusts, and currency trusts, in each case that are traded on a U.S. securities exchange; common stocks listed on a foreign exchange that trade on such exchange contemporaneously with the Fund’s shares; exchange-traded futures (where the future contract’s reference asset is an asset that the Fund could invest in directly, or in the case of an index future, is based on an index of a type of asset that the Fund could invest in directly) that are traded on a U.S. futures exchange contemporaneously with the Fund’s shares; and cash and cash equivalents, which are short-term U.S. Treasury securities, government money market funds, and repurchase agreements (collectively, Permitted Investment Types). The Fund may invest in any of the Permitted Investment Types. These investments and their risks are described in the SAI. The Fund may not borrow for investment purposes or hold short positions. The Fund may not purchase any securities that are illiquid investments at the time of purchase.

Investing Defensively

The Fund may from time to time take temporary defensive investment positions that may be inconsistent with the Fund’s principal investment strategies in attempting to respond to adverse market, economic, political, social or other conditions, including, without limitation, investing some or all of its assets in money market instruments or shares of affiliated or unaffiliated government money market funds or holding some or all of its assets in cash or cash equivalents. The Fund may take such defensive investment positions for as long a period as deemed necessary.

The Fund may not achieve its investment objective while it is investing defensively. Investing defensively may adversely affect Fund performance. During these times, the portfolio managers may make frequent portfolio holding changes, which could result in increased trading expenses taxes and decreased Fund performance.

Other Strategic and Investment Measures

The Fund may also from time to time take temporary portfolio positions that may or may not be consistent with the Fund’s principal investment strategies in attempting to respond to adverse market, economic, political, social or other conditions, including, without limitation, investing in exchange-traded futures contracts for various purposes, including among others, in seeking to reduce investment exposures, or in seeking to achieve indirect investment exposures, to a sector, country, region or currency where the Investment Manager believes such positioning is appropriate. The Fund may take such portfolio positions for as long a period as deemed necessary. While the Fund is so positioned, the Fund may not achieve its investment objective. Investing in this manner may adversely affect Fund performance. During these times, the portfolio managers may make frequent portfolio holding changes, which could result in increased trading expenses and taxes, and decreased Fund performance.

Understanding Annual Fund Operating Expenses

The Fund’s annual operating expenses, as presented in the Annual Fund Operating Expenses table in the Fees and Expenses of the Fund section of this prospectus, generally are based on estimated expenses for the Fund’s current fiscal year and are expressed as a percentage (expense ratio). The expense ratio reflects the Fund’s fee

Primary Service Provider Contracts

The Fund enters into contractual arrangements (Service Provider Contracts) with various service providers, including, among others, the Investment Manager, the administrator, the distributor, the transfer agent and the Fund’s custodian. The Fund’s Service Provider Contracts are solely among the parties thereto. Shareholders are not parties to, or intended to be third-party beneficiaries of, any Service Provider Contracts. Further, this prospectus, the SAI and any Service Provider Contracts are not intended to give rise to any agreement, duty, special relationship or other obligation between the Fund and any investor, or give rise to any contractual, tort or other rights in any individual shareholder, group of shareholders or other person, including any right to assert a fiduciary or other duty, enforce the Service Provider Contracts against the parties or to seek any remedy thereunder, either directly or on behalf of the Fund. Nothing in the previous sentence should be read to suggest any waiver of any rights under federal or state securities laws.

The Investment Manager

Columbia Management Investment Advisers, LLC is located at 290 Congress Street, Boston, MA 02210 and serves as investment adviser to the Columbia Funds, including the Fund. The Investment Manager is a registered investment adviser and a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). The Investment Manager’s management experience covers all major asset classes, including equity securities, debt instruments and money market instruments. In addition to serving as an investment adviser to traditional mutual funds, exchange-traded funds and closed-end funds, the Investment Manager acts as an investment adviser for itself, its affiliates, individuals, corporations, retirement plans, private investment companies and financial intermediaries.

Subject to oversight by the Board, the Investment Manager manages the day-to-day operations of the Fund.

The SEC has issued an order that permits the Investment Manager, subject to the approval of the Board, to appoint affiliated and unaffiliated subadvisers by entering into subadvisory agreements with them, and to change in material respects the terms of those subadvisory agreements, including the fees paid thereunder, for the Fund without first obtaining shareholder approval, thereby avoiding the expense and delays typically associated with obtaining shareholder approval. The Fund furnishes shareholders with information about new subadvisers retained in reliance on the order within 90 days after hiring the subadviser. The Investment Manager and its affiliates may have other relationships, including significant financial relationships, with current or potential subadvisers or their affiliates, which may create certain conflicts of interest. When making recommendations to the Board to appoint or to change a subadviser, or to change the terms of a subadvisory agreement, the Investment Manager discloses to the Board the nature of any such material relationships. The SEC has issued a separate order that permits the Board to approve new subadvisory agreements or material changes to existing subadvisory agreements at a meeting that is not in person, provided that the Trustees are able to participate in the meeting using a means of communication that allows them to hear each other simultaneously during the meeting and other conditions of the order are satisfied. At present, the Investment Manager has not engaged any investment subadviser for the Fund.

The Fund pays the Investment Manager a fee for its investment advisory services. The fee is calculated as a percentage of the daily net assets of the Fund and is paid monthly. The fee is [__]% of the Fund’s average daily net assets on all assets. In return for this fee (which is sometimes referred to as a unitary or unified fee), the Investment Manager has agreed to pay the operating costs and expenses of the Fund other than the following expenses, which will be paid by the Fund: taxes, interest incurred on borrowing by the Fund, if any, brokerage fees and commissions, interest and fee expense related to the Fund’s participation in inverse floater structures and any other portfolio transaction expenses, infrequent and/or unusual expenses, including without limitation litigation expenses, distribution and/or service fees, expenses incurred in connection with lending securities, and any other expenses approved by the Board.

A discussion regarding the basis for the Board’s approval of the adoption of the investment management services agreement with the Investment Manager will be available in the Fund’s [annual/semiannual] report to shareholders for the fiscal [year/period] ending [_____].

Other Roles and Relationships of Ameriprise Financial and its Affiliates — Certain Conflicts of Interest

The Investment Manager provides various services to the Fund and other Columbia Funds for which it is compensated. Ameriprise Financial and its affiliates may also provide other services to these funds and be compensated for them.

The Investment Manager and its affiliates may provide investment advisory and other services to other clients and customers substantially similar to those provided to the Columbia Funds. These activities, and other financial services activities of Ameriprise Financial and its affiliates, may present actual and potential conflicts of interest and introduce certain investment constraints.

Ameriprise Financial is a major financial services company, engaged in a broad range of financial activities beyond the fund-related activities of the Investment Manager, including, among others, insurance, broker-dealer (sales and trading), asset management, banking and other financial activities. These additional activities may involve multiple advisory, financial, insurance and other interests in securities and other instruments, and in companies that issue securities and other instruments, that may be bought, sold or held by the Columbia Funds.

Conflicts of interest and limitations that could affect a Columbia Fund may arise from, for example, the following:

■	compensation and other benefits received by the Investment Manager and other Ameriprise Financial affiliates related to the management/administration of a Columbia Fund and the sale of its shares;

■	the allocation of, and competition for, investment opportunities among the Fund, other funds and accounts advised/managed by the Investment Manager and other Ameriprise Financial affiliates, or Ameriprise Financial itself and its affiliates;

■	separate and potentially divergent management of a Columbia Fund and other funds and accounts advised/managed by the Investment Manager and other Ameriprise Financial affiliates;

■	regulatory and other investment restrictions on investment activities of the Investment Manager and other Ameriprise Financial affiliates and accounts advised/managed by them;

■	insurance and other relationships of Ameriprise Financial affiliates with companies and other entities in which a Columbia Fund invests; and

■	regulatory and other restrictions relating to the sharing of information between Ameriprise Financial and its affiliates, including the Investment Manager, and a Columbia Fund.

The Investment Manager and Ameriprise Financial have adopted various policies and procedures that are intended to identify, monitor and address conflicts of interest. However, there is no assurance that these policies, procedures and disclosures will be effective.

Additional information about Ameriprise Financial and the types of conflicts of interest and other matters referenced above is set forth in the Investment Management and Other Services — Other Roles and Relationships of Ameriprise Financial and its Affiliates — Certain Conflicts of Interest section of the SAI. Investors in the Columbia Funds should carefully review these disclosures and consult with their financial advisor if they have any questions.

Buying and Selling Fund Shares

Shares are issued or redeemed by the Fund at NAV per share only in Creation Units of [_____] shares.

Shares trade on the secondary market, which is where most retail investors will buy and sell shares. It is expected that only a limited number of institutional investors will purchase and redeem shares directly from the Fund. Thus, certain information in this prospectus is not relevant to most retail investors. For example, information about buying and redeeming Creation Units directly from the Fund and about transaction fees imposed on such purchases and redemptions is not relevant to most retail investors.

Except when aggregated in Creation Units, the Fund’s shares are not redeemable with the Fund. Additional information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the SAI.

Buying and Selling Fund Shares on the Secondary Market

The Fund issues or redeems its shares at NAV per share only in Creation Units and only to Authorized Participants (or APs). Most investors will buy and sell shares in secondary market transactions through brokers or other financial intermediaries, and therefore must have an account with them to buy and sell shares. Shares can be bought or sold through your financial intermediary throughout the trading day like shares of any publicly traded issuer. When buying or selling shares through a financial intermediary, you will incur customary brokerage commissions and charges, and you may pay some or all of the spread between the bid and the offered prices in the secondary market for shares. The price at which you buy or sell shares (i.e., the market price) may be more or less than the NAV of the shares. Unless imposed by your financial intermediary, there is no minimum dollar amount you must invest in the Fund and no minimum number of shares you must buy.

Shares of the Fund are listed on [____________] under the symbol: SEMI

The Exchange is generally open Monday through Friday and is closed for weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.

For information about buying and selling shares on the Exchange or in the secondary markets, please contact your financial intermediary.

Book Entry. Shares are held in book entry form, which means that no stock certificates are issued. The Depository Trust Company (DTC), or its nominee, is the registered owner of all outstanding shares of the Fund and is recognized as the owner of all shares. Participants in DTC include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of Fund Shares certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely on the procedures of DTC and its participants. These procedures are the same as those that apply to any stocks that you hold in book entry or “street name” through your brokerage account. Your account information will be maintained by your financial intermediary, which will provide you with account statements, confirmations of your purchases and sales of shares, and tax information. Your financial intermediary also will be responsible for distributing income dividends and capital gain distributions and for ensuring that you receive shareholder reports and other communications from the Fund.

Share Trading Prices. The trading prices of the Fund’s shares may differ from the Fund’s daily NAV and can be affected by market forces of supply and demand for the Fund’s shares, the prices of the Fund’s investments, economic conditions and other factors. The Exchange or another market information provider intends to disseminate the approximate value of the Fund’s portfolio every fifteen seconds. This approximate value should not be viewed as a “real-time” update of the NAV of the Fund because the approximate value may not be calculated in the same manner as the NAV, which is computed once a day. The quotations for certain investments may not be updated during U.S. trading hours if such holdings do not trade in the U.S., except such quotations may be updated to reflect currency fluctuations. The Fund is not involved in, or responsible for, the calculation or dissemination of the approximate values and makes no warranty as to the accuracy of these values.

Buying and Selling Fund Shares (continued)

Buying Fund Shares Directly from the Fund

Fund shares can only be purchased directly from the Fund by or through an Authorized Participant. The Fund issues or redeems its shares at NAV per share only in Creation Units and only to Authorized Participants (or APs). An “Authorized Participant” is a participant of the Continuous Net Settlement System of the NSCC or the DTC that has executed a Participant Agreement with the Distributor, and accepted by the Transfer Agent. The Distributor will provide a list of Authorized Participants upon request. Authorized Participants may purchase Creation Units of shares, and sell individual shares on the Exchange. See Continuous Offering below.

An Authorized Participant can purchase Fund shares directly from the Fund only in Creation Units or multiples thereof. The number of shares in a Creation Unit may, but is not expected to, change over time. The Fund will not issue fractional Creation Units. Creation Units may be purchased in exchange for a basket of securities or other portfolio instruments (known as the In-Kind Creation Basket and a Cash Component) or for an all cash payment (that would be treated as the Cash Component (discussed below) in connection with purchases not involving an In-Kind Creation Basket). The Fund reserves the right to reject any purchase request at any time, for any reason, and without notice.

In-Kind Creation Basket. The Fund's In-Kind Creation Basket on a given business day is its Tracking Basket. So, all references herein to In-Kind Creation Basket refer to that day's Tracking Basket. On each business day, prior to the opening of trading on the Exchange, [___] will post on the NSCC bulletin board the In-Kind Creation Basket for the Fund for that day. The In-Kind Creation Basket will identify the name and number of shares of each security or other instrument that must be contributed to the Fund for each Creation Unit purchased (cash in lieu of contributing Representative ETFs). The Fund reserves the right to accept a nonconforming or “custom” In-Kind Creation Basket under certain limited circumstances.

Balancing Amount and Cash Component. In addition to the In-Kind Creation Basket, a purchaser will either pay to, or receive from, the Fund an amount of cash (“Balancing Amount”) equal to the difference between the NAV of a Creation Unit and the value of the securities in the In-Kind Creation Basket. The Balancing Amount ensures that the consideration paid by an investor for a Creation Unit is exactly equal to the value of the Creation Unit. [___] will publish, on a daily basis, information about the previous business day’s Balancing Amount. To the extent a purchaser is not owed a Balancing Amount larger than the Creation Transaction Fee, described below, the purchaser also must pay a Creation Transaction Fee, in cash. The Balancing Amount and the Creation Transaction Fee, taken together, are referred to as the Cash Component.

Placement of Purchase Orders. All purchase orders must be placed by or through an Authorized Participant. Purchase orders will be processed either through a manual clearing process run by DTC or through an enhanced clearing process that is available only to those DTC participants that also are participants in the Continuous Net Settlement System of the NSCC. Authorized Participants that do not use the NSCC’s enhanced clearing process may be charged a higher Creation Transaction Fee (discussed below). A purchase order must be received by the Distributor at least two hours before the scheduled closing of trading on the NYSE (generally 4:00 p.m., Eastern time) on the day the order is placed, and all other procedures set forth in the Participant Agreement must be followed, in order to receive the NAV determined on that day. Notwithstanding the forgoing, the Trust may, but is not required to, permit non-standard orders until 4:00 p.m., Eastern time, or until the market close (in the event the Exchange closes early). In the case of custom orders, the order must be received by the Distributor no later than two hours before the scheduled close of trading on the NYSE.

Transaction Fee on Purchases of Creation Units. The Fund may impose a “Creation Transaction Fee” on each purchase of Creation Units. The Creation Transaction Fee for purchases effected through the NSCC’s enhanced clearing process, regardless of the number of Creation Units purchased, is [$____].

A higher Creation Transaction Fee noted above may be imposed on purchases outside the NSCC’s enhanced clearing process, including purchases involving nonconforming In-Kind Creation Baskets or cash. Investors who, directly or indirectly, use the services of a broker or other such intermediary to compile the securities or other instruments in the In-Kind Creation Basket may pay additional fees for these services.

Redeeming Fund Shares Directly from the Fund

Fund shares can only be redeemed directly with the Fund by or through an Authorized Participant. An Authorized Participant may redeem Fund shares directly from the Fund only in Creation Units or multiples thereof. As noted above, the Fund issues or redeems its shares at NAV per share only in Creation Units and only to Authorized Participants (or APs). Creation Units may be redeemed in exchange for a basket of securities or other instruments (known as the In-Kind Redemption Basket and a Cash Component) or, in certain circumstances, for all cash payment (that would be treated as the Cash Component (discussed below) in connection with purchases not involving an In-Kind Redemption Basket). The Fund can suspend redemptions or postpone payment of redemption proceeds for any period during which: (1) the New York Stock Exchange (NYSE) is closed other than customary weekend and holiday closings; (2) trading on the NYSE is suspended or restricted; (3) an emergency exists as a result of which disposal of Fund shares or determination of the Fund’s NAV is not reasonably practicable or it is not reasonably practicable for the Fund to fairly determine the value of its net assets; and (4) the SEC by order permits for the protection of shareholders of a Fund. The Fund may also postpone payment of redemption proceeds for up to 15 calendar days due to holdings in non-U.S. investments.

In-Kind Redemption Basket. The Fund’s In-Kind Redemption Basket on a given business day is its Tracking Basket. So, all references herein to In-Kind Redemption Basket refer to that day’s Tracking Basket. Redemption proceeds will generally be paid in kind with a basket of securities or other portfolio instruments known as the In-Kind Redemption Basket. In most cases, the In-Kind Redemption Basket will be the same as the In-Kind Creation Basket for that same day (cash in lieu with respect to Representative ETFs). There will be times, however, when the In-Kind Creation Basket and In-Kind Redemption Baskets differ. The composition of the In-Kind Redemption Basket will be available on the NSCC bulletin board each day the NYSE is open for business. The Fund may honor a redemption request with a nonconforming or “custom” In-Kind Redemption Basket under certain limited circumstances.

Balancing Amount and Cash Component. Depending on whether the NAV of a Creation Unit is higher or lower than the value of the securities or other portfolio instruments in the In-Kind Redemption Basket, a redeeming investor will either receive from, or pay to, the Fund a Balancing Amount in cash. If due to receive a Balancing Amount, the amount actually received will be reduced by the amount of the applicable Redemption Transaction Fee, described below. The Balancing Amount and the Redemption Transaction Fee, taken together, are referred to as the Cash Component.

Cash Value. In lieu of the In-Kind Redemption Basket and a Balancing Amount, Creation Units may be redeemed for a Fund Redemption consisting solely of cash in an amount equal to the NAV of a Creation Unit, which amount is referred to as the Cash Value. Such redemptions will be subject to a variable charge, as explained above. The transfer agent will publish, on a daily basis, information about the Cash Value of a Creation Unit. With respect to any Fund Redemption consisting of a Cash Value, the Cash Value and Redemption Transaction Fee, taken together, are referred to as the Cash Component.

Placement of Redemption Orders. As with purchases, redemptions must be processed either through the DTC process or the enhanced NSCC process. A redemption order is deemed received on the date of transmittal if it is received by the Distributor at least two hours before the scheduled closing of trading on the NYSE, and if all other procedures set forth in the Participant Agreement are followed. In the case of custom orders, the order must be received by the Distributor no later than two hours before the scheduled close of trading on the NYSE.

Transaction Fee on Redemptions of Creation Units. The Fund imposes a “Redemption Transaction Fee” on each redemption of Creation Units. The amount of the Redemption Transaction Fee on redemptions effected through the NSCC and DTC, and on nonconforming or "custom" redemptions, is the same as the Creation Transaction Fee.

Additional Information About Buying and Selling Fund Shares

Legal Restrictions on Transactions in Certain Securities. An investor subject to a legal restriction with respect to a particular security required to be deposited in connection with the purchase of a Creation Unit may, at the Fund’s discretion, be permitted to deposit an equivalent amount of cash in substitution for any security which would otherwise be included in the In-Kind Creation Basket applicable to the purchase of a Creation Unit.

26	Prospectus 2022

Table of Contents

Columbia Seligman Semiconductor Technology ETF

Buying and Selling Fund Shares (continued)

Creations and redemptions of shares will be subject to applicable federal and state securities laws, including that securities accepted for deposit and securities used to satisfy redemption requests are sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the Securities Act). The Fund (whether or not it otherwise permits cash redemptions) reserves the right to redeem Creation Units for cash to the extent that an investor could not lawfully purchase or the Fund could not lawfully deliver specific securities under such laws or the local laws of a jurisdiction in which the Fund invests. An Authorized Participant or an investor for which it is acting subject to a legal restriction with respect to a particular security included in an In-Kind Redemption Basket may be paid an equivalent amount of cash. An Authorized Participant or redeeming investor for which it is acting that is not a qualified institutional buyer (QIB) as defined in Rule 144A under the Securities Act will not be able to receive, as part of a redemption, restricted securities eligible for resale under Rule 144A.

Continuous Offering. Authorized Participants should be aware of certain legal risks unique to investors purchasing Creation Units directly from the Fund. Because shares may be issued on an ongoing basis, a “distribution” of shares could be occurring at any time. Certain activities that Authorized Participants perform with respect to the sale of shares could, depending on the circumstances, result in Authorized Participants being deemed to be a participant in the distribution, in a manner that could render Authorized Participants a statutory underwriter and subject Authorized Participants to the prospectus delivery and liability provisions of the Securities Act. For example, Authorized Participants could be deemed a statutory underwriter if Authorized Participants purchase Creation Units from the issuing Fund, break them down into the constituent shares, and sell those shares directly to customers, or if Authorized Participants choose to couple the creation of a supply of new shares with an active selling effort involving solicitation of secondary market demand for shares. Whether a person is an underwriter for purposes of the Securities Act depends upon all of the facts and circumstances pertaining to that person’s activities, and the examples mentioned here should not be considered a complete description of all the activities that could cause Authorized Participants to be deemed 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, are generally 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. As a result, broker-dealer firms should note that dealers who are not “underwriters” but are participating in a distribution (as opposed to engaging in ordinary secondary market transactions), and thus dealing with shares as part of an unsold allotment within the meaning of Section 4(3)(C) of the Securities Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the Securities Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the Securities Act is only available with respect to transactions on a national exchange.

Active Investors and Market Timing

The Board has determined not to adopt policies and procedures designed to prevent or monitor for frequent purchases and redemptions of the Fund’s shares because investors primarily transact in Fund shares on the secondary market. Frequent trading of shares on the secondary market does not disrupt portfolio management, increase the Fund’s trading costs, lead to realization of capital gains or otherwise harm Fund shareholders because these trades do not involve the issuance or redemption of Fund shares.

The Fund sells and redeems its shares at NAV only in Creation Units pursuant to the terms of a Participant Agreement between an Authorized Participant and the Distributor. With respect to such trades directly with the Fund to the extent effected in-kind (i.e., for securities), they generally would not cause the harmful effects that may result from frequent cash trades.

The Board recognizes that to the extent that the Fund allows or requires trades to be effected in whole or in part in cash, those trades could result in dilution to a Fund and increased transaction costs, which could negatively impact the Fund’s ability to achieve its investment objective. The Board also recognizes, however, that direct trading by Authorized Participants is critical to ensuring that the Fund’s shares trade at or close to NAV. Further, the Fund may

Prospectus 2022

Table of Contents

Columbia Seligman Semiconductor Technology ETF

Buying and Selling Fund Shares (continued)

employ fair valuation pricing to minimize the potential for dilution from market timing. Moreover, the Fund imposes transaction fees on purchases and redemptions of Fund shares reflecting the fact that the Fund’s costs increase in those circumstances. The Fund reserves the right to impose additional restrictions on disruptive, excessive or short-term purchases.

Distribution and Service Fees

The Board has approved, and the Fund has adopted, a distribution and service plan (the Plan) pursuant to Rule 12b-1 under the 1940 Act. Under the Plan, the Fund is authorized to pay distribution fees to the Distributor and other firms that provide distribution and shareholder services (Service Providers). If a Service Provider provides such services, the Fund may pay fees at an annual rate not to exceed [___]% of average daily net assets, pursuant to Rule 12b-1 under the 1940 Act.

No distribution or service fees are currently paid by the Fund, however, and there are no current plans to impose these fees. Future payments may be made under the Plan without any further shareholder approval. In the event Rule 12b-1 fees are charged, over time they would increase the cost of an investment in the Fund.

Determination of Net Asset Value

FUNDamentals

NAV Calculation

The Fund calculates its NAV as follows:

NAV = (Value of assets) – (Liabilities)
Number of outstanding shares

FUNDamentals

Business days

A business day is any day that the New York Stock Exchange (NYSE) is open. A business day typically ends at the close of regular trading on the NYSE, usually at 4:00 p.m. Eastern time. If the NYSE is scheduled to close early, the business day will be considered to end as of the time of the NYSE’s scheduled close. For purposes of this section only, the Fund will not treat an intraday unscheduled disruption in NYSE trading or an intraday unscheduled closing as a close of regular trading on the NYSE for these purposes and will price its shares as of the regularly scheduled closing time for that day (typically, 4:00 p.m. Eastern time). Notwithstanding the foregoing, the NAV of Fund shares may be determined at such other time or times (in addition to or in lieu of the time set forth above) as the Fund’s Board may approve or ratify. On holidays and other days when the NYSE is closed, the Fund’s NAV is not calculated and the Fund does not accept buy or sell orders. However, the value of the Fund’s assets may still be affected on such days to the extent that the Fund holds foreign securities that trade on days that foreign securities markets are open.

Equity securities are valued primarily on the basis of market quotations reported on stock exchanges and other securities markets around the world. If an equity security is listed on a national exchange, the security is valued at the closing price or, if the closing price is not readily available, the mean of the closing bid and asked prices. Certain equity securities, debt securities and other assets are valued differently. For instance, bank loans trading in the secondary market are valued primarily on the basis of indicative bids, fixed income investments maturing in 60 days or less are valued primarily using the amortized cost method, unless this methodology results in a valuation that does not approximate the market value of these securities, and those maturing in excess of 60 days are valued primarily using a market-based price obtained from a pricing service, if available. Investments in other open-end funds are valued at their published NAVs. Both market quotations and indicative bids are obtained from outside pricing services approved and monitored pursuant to a policy approved by the Fund's Board.

Buying and Selling Fund Shares (continued)

If a market price is not readily available or is deemed not to reflect market value, the Fund will determine the price of a portfolio security based on a determination of the security's fair value pursuant to a policy approved by the Fund's Board. In addition, the Fund may use fair valuation to price securities that trade on a foreign exchange when a significant event has occurred after the foreign exchange closes but before the time at which the Fund's share price is calculated. Foreign exchanges typically close before the time at which Fund share prices are calculated, and may be closed altogether on some days when the Fund is open. Such significant events affecting a foreign security may include, but are not limited to: (1) corporate actions, earnings announcements, litigation or other events impacting a single issuer; (2) governmental action that affects securities in one sector or country; (3) natural disasters or armed conflicts affecting a country or region; or (4) significant domestic or foreign market fluctuations. The Fund uses various criteria in determining whether a foreign security's market price is readily available and reflective of market value and, if not, the fair value of the security. To the extent the Fund has significant holdings of small cap stocks, high-yield bonds, floating rate loans, or tax-exempt, foreign or other securities that may trade infrequently, fair valuation may be used more frequently than for other funds.

Fair valuation may have the effect of reducing stale pricing arbitrage opportunities presented by the pricing of Fund shares. However, when the Fund uses fair valuation to price securities, it may value those securities higher or lower than another fund would have priced the security. Also, the use of fair valuation may cause the Fund's performance to diverge to a greater degree from the performance of various benchmarks used to compare the Fund's performance because benchmarks generally do not use fair valuation techniques. Because of the judgment involved in fair valuation decisions, there can be no assurance that the value ascribed to a particular security is accurate.

Distributions and Taxes

Distributions to Shareholders

A fund can make money two ways:

■	It can earn income on its investments. Examples of fund income are interest paid on money market instruments and dividends paid on common stocks.

■

A fund can also have capital gains if the value of its investments increases. While a fund continues to hold an investment, any gain is generally unrealized. If the fund sells an investment, it generally will realize a capital gain if it sells that investment for a higher price than its adjusted cost basis, and will generally realize a capital loss if it sells that investment for a lower price than its adjusted cost basis. Capital gains and losses are either short-term or long-term, depending on whether the fund holds the securities for one year or less (short-term) or more than one year (long-term).

Funds make payments of fund earnings to shareholders, distributing them among all shareholders of the fund. As a shareholder, you are entitled to your portion of a fund's distributed income, including capital gains. Reinvesting your distributions buys you more shares of a fund — which lets you take advantage of the potential for compound growth. Putting the money you earn back into your investment means it, in turn, may earn even more money (or be exposed to additional losses, if the fund earns a negative return). Over time, the power of compounding has the potential to significantly increase the value of your investment. There is no assurance, however, that you'll earn more money if you reinvest your distributions rather than receive them in cash.

Brokers may make available to their customers who own shares the DTC book-entry dividend reinvestment service. To determine whether the dividend reinvestment service is available and whether there is a commission or other charge for using this service, consult your broker. Brokers may require Fund shareholders to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and net realized gains will be automatically reinvested in additional whole shares of the distributing Fund purchased in the secondary market. Without this service, investors would receive their distributions in cash.

The Fund intends to pay out, in the form of distributions to shareholders, a sufficient amount of its income and gains so that the Fund will qualify for treatment as a regulated investment company and generally will not have to pay any federal excise tax. The Fund generally intends to distribute any net realized capital gain (whether long-term or short-term gain) at least once a year. Normally, the Fund will declare and pay distributions of net investment income according to the following schedule:

Declaration and Distribution Schedule
Declarations	[___]
Distributions	[___]

The Fund may declare or pay distributions of net investment income more frequently.

Each time a distribution is made, the NAV per share is reduced by the amount of the distribution.

The Fund generally pays cash distributions within five business days after the distribution was declared. If you sell all of your shares after the record date, but before the payment date, for a distribution, you'll normally receive that distribution in cash within five business days after the sale was made.

Unless you are a tax-exempt investor or holding Fund shares through a tax-advantaged account (such as a 401(k) plan or IRA), you should consider avoiding buying Fund shares shortly before the Fund makes a distribution (other than distributions of net investment income that are declared daily) of net investment income or net realized capital gain, because doing so can cost you money in taxes to the extent the distribution consists of taxable income or gains. This is because you will, in effect, receive part of your purchase price back in the distribution. This is known as “buying a dividend.” To avoid “buying a dividend,” before you invest check the Fund's distribution schedule, which is available at the Funds' website and/or by calling 888.800.4347.

Columbia Seligman Semiconductor Technology ETF

Distributions and Taxes (continued)

Taxes

You should be aware of the following considerations applicable to the Fund:

■

The Fund intends to qualify and to be eligible for treatment each year as a regulated investment company. A regulated investment company generally is not subject to tax at the fund level on income and gains from investments that are distributed to shareholders. However, the Fund's failure to qualify for treatment as a regulated investment company would result in Fund-level taxation, and consequently, a reduction in income available for distribution to you and in the NAV of your shares. Even if the Fund qualifies for treatment as a regulated investment company, the Fund may be subject to federal excise tax on certain undistributed income or gains.

■

Otherwise taxable distributions generally are taxable to you when paid, whether they are paid in cash or automatically reinvested in additional Fund shares. Dividends paid in January are deemed paid on December 31 of the prior year if the dividend was declared and payable to shareholders of record in October, November, or December of such prior year.

■

Distributions of the Fund's ordinary income and net short-term capital gain, if any, generally are taxable to you as ordinary income. Distributions of the Fund's net long-term capital gain, if any, generally are taxable to you as long-term capital gain. Whether capital gains are long-term or short-term is determined by how long the Fund has owned the investments that generated them, rather than how long you have owned your shares.

■

From time to time, a distribution from the Fund could constitute a return of capital. A return of capital is a return of an amount of your original investment and is not a distribution of income or capital gain from the Fund. Therefore, a return of capital is not taxable to you so long as the amount of the distribution does not exceed your tax basis in your Fund shares. A return of capital reduces your tax basis in your Fund shares, with any amounts exceeding such basis generally taxable as capital gain.

■

If you are an individual and you meet certain holding period and other requirements for your Fund shares, a portion of your distributions may be treated as “qualified dividend income” taxable at the lower net long-term capital gain rates instead of the higher ordinary income rates. Qualified dividend income is income attributable to the Fund's dividends received from certain U.S. and foreign corporations, as long as the Fund meets certain holding period and other requirements for the stock producing such dividends.

■	Certain high-income individuals (as well as estates and trusts) are subject to a 3.8% tax on net investment income. For individuals, the 3.8% tax applies to the lesser of (1) the amount (if any) by which the taxpayer's modified adjusted gross income exceeds certain threshold amounts or (2) the taxpayer's “net investment income.”
	Net investment income generally includes for this purpose dividends, including any capital gain dividends, paid by the Fund, and net gains recognized on the sale, redemption or exchange of shares of the Fund.

■

Certain derivative instruments when held in the Fund's portfolio subject the Fund to special tax rules, the effect of which may be to, among other things, accelerate income to the Fund, defer Fund losses, cause adjustments in the holding periods of Fund portfolio securities, or convert capital gains into ordinary income, short-term capital losses into long-term capital losses or long-term capital gains into short-term capital gains. These rules could therefore affect the amount, timing and/or character of distributions to shareholders.

■

Generally, a Fund realizes a capital gain or loss on an option when the option expires, or when it is exercised, sold or otherwise terminated. However, if an option is a “section 1256 contract,” which includes most traded options on a broad-based index, and the Fund holds such option at the end of its taxable year, the Fund is deemed to sell such option at fair market value at such time and recognize any gain or loss thereon, which is generally deemed to be 60% long-term and 40% short-term capital gain or loss, as described further in the SAI.

■

Income and proceeds received by the Fund from sources within foreign countries may be subject to foreign taxes. If at the end of the taxable year more than 50% of the value of the Fund's assets consists of securities of foreign corporations, and the Fund makes a special election, you will generally be required to include in your income for U.S. federal income tax purposes your share of the qualifying foreign income taxes paid by the Fund in respect of

Prospectus 2022

Table of Contents

Distributions and Taxes (continued)

its foreign portfolio securities. You may be able to claim a foreign tax credit or deduction in respect of this amount, subject to certain limitations. There is no assurance that the Fund will make this election for a taxable year, even if it is eligible to do so.

■

A sale, redemption or exchange of Fund shares is a taxable event. This includes redemptions where you are paid in securities. Your sales, redemptions and exchanges of Fund shares, including those paid in securities or other instruments, usually will result in a taxable capital gain or loss to you, equal to the difference between the amount you receive for your shares (or are deemed to have received in the case of exchanges) and your adjusted tax basis in the shares, which is generally the amount you paid (or are deemed to have paid in the case of exchanges) for them. Any such capital gain or loss generally will be long-term capital gain or loss if you have held your Fund shares for more than one year at the time of sale or exchange. In certain circumstances, capital losses may be converted from short-term to long-term; in other circumstances, capital losses may be disallowed under the “wash sale” rules.

■

Your broker will be responsible for furnishing tax reporting information for Fund shares held in a nonqualified account, shareholder reports, and other communications from the Fund. For sales or exchanges of Fund shares acquired in a nonqualified account after 2011, your broker is required to report basis and holding period information to you and the IRS. Your broker may offer a choice of basis calculation methods. Contact your broker to determine which basis methods are available for your account.

■

The Fund or, in the case of sales of Fund shares in the secondary market, your broker, will generally be required by federal law to withhold tax on any distributions and proceeds paid to you if you have not provided a correct TIN or have not certified to the Fund or its agent, or your broker, as the case may be, that withholding does not apply.

■

For Authorized Participants Purchasing and Redeeming in Creation Units: An Authorized Participant that exchanges equity securities for one or more Creation Units will generally recognize a gain or a loss on the exchange. The gain or loss will be equal to the difference between (i) the market value of the Creation Unit(s) at the time and, (ii) the exchanger’s aggregate basis in the securities surrendered plus (or minus) the Cash Component paid (or received). A person who redeems one or more Creation Units for equity securities will generally recognize a gain or loss equal to the difference between (i) the exchanger’s basis in the Creation Unit(s) and, (ii) the aggregate market value of the securities received plus (or minus) the Cash Component received (or paid). The IRS, however, may assert that a loss realized upon an exchange of securities for Creation Unit(s) cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position. Persons exchanging securities should consult their own tax advisors with respect to whether wash sale rules apply and when a loss might be deductible. Any capital gain or loss realized upon a redemption of one or more Creation Units is generally treated as long-term capital gain or loss if the Creation Unit(s) have been held for more than one year and as short-term capital gain or loss if they have been held for one year or less. If you purchase or redeem Creation Units, you will be sent a confirmation statement showing how many shares you purchased or sold and at what price.

*Columbia Seligman Semiconductor Technology ETF is different from traditional ETFs.

Traditional ETFs tell the public what assets they hold each day. Columbia Seligman Semiconductor Technology ETF will not. This may create additional risks for your investment. For example:

■	You may have to pay more money to trade this ETF’s shares. This ETF will provide less information to traders, who tend to charge more for trades when they have less information.
■	The price you pay to buy this ETF shares on an exchange may not match the value of the ETF’s portfolio. The same is true when you sell shares. These price differences may be greater for this ETF compared to other ETFs because it provides less information to traders.
■	These additional risks may be even greater in bad or uncertain market conditions.
■	This ETF will publish on its website each day a “Tracking Basket” designed to help trading in shares of the ETF. While the Tracking Basket includes some of the ETF’s holdings, it is not the ETF’s actual portfolio.

The differences between Columbia Seligman Semiconductor Technology ETF and other ETFs may also have advantages. By keeping certain information about this ETF secret, this ETF may face less risk that other traders can predict or copy its investment strategy. This may improve this ETF’s performance. If other traders are able to copy or predict this ETF’s investment strategy, however, this may hurt the ETF’s performance.

SAI PRIMER

The SAI is a part of the Funds' registration statement that is filed with the SEC. The registration statement includes the Funds' prospectuses, the SAI and certain exhibits. The SAI, as supplemented from time to time, can be found online at columbiathreadneedleus.com/etfs and/or by accessing the SEC’s website at www.sec.gov.

For purposes of any electronic version of this SAI, all references to websites or universal resource locators (URLs) are intended to be inactive and are not meant to incorporate the contents of any such website or URL into this SAI, with the exception of the most recent annual report for each Fund, as noted on the front cover of this SAI.

The SAI generally provides additional information about the Funds that is not required to be in the Funds' prospectuses. The SAI expands discussions of certain matters described in the Funds' prospectuses and provides certain additional information about the Funds that may be of help or interest to some investors. Among other things, the SAI provides information about:

■	the organization of each Trust (of which the Funds are a series);

■	the Funds' investments;
■	the Funds' investment adviser, investment subadviser(s) (if any) and other service providers, including roles and relationships of Ameriprise Financial and its affiliates, and conflicts of interest;
■	the governance of the Funds;
■	the Funds' brokerage practices;
■	the purchase, redemption and pricing of Fund Creation Units; and
■	the application of U.S. federal income tax laws.

If you have any questions about the Funds, please call Columbia Funds at [__________] or contact your financial advisor.

Throughout this SAI, the term “financial intermediary” may refer, generally, to one or more of the selling agents and/or servicing agents that are authorized to sell and/or service shares of the Funds, which may include broker-dealers and financial advisors as well as firms that employ such broker-dealers and financial advisors, including, for example, brokerage firms, banks, investment advisers, third party administrators and other financial intermediaries.

Each Fund typically updates its registration statement approximately four months after the end of its fiscal year, although in certain circumstances a Fund may update its registration statement sooner. Some of the information in this SAI is reported for a Fund as of the end of the Fund’s last fiscal year (or period) or during the Fund’s last fiscal year (or period), as applicable. This is a reference to the fiscal year (or period) ending prior to the Fund’s last annual update, which may be fifteen months or more prior to the date of the SAI. See About the Trusts for each Fund’s fiscal year end and most recent prospectus date (i.e., the date of the Fund’s last annual update).

Columbia Threadneedle Investments is the global brand name of the Columbia and Threadneedle group of companies.

*	A “diversified” Fund may not, with respect to 75% of its total assets, invest more than 5% of its total assets in securities of any one issuer or purchase more than 10% of the outstanding voting securities of any one issuer, except obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities and except securities of other investment companies. A “non-diversified” Fund may invest a greater percentage of its total assets in the securities of fewer issuers than a “diversified” fund, which increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a “diversified” fund holding a greater number of investments. Accordingly, a “non-diversified” Fund’s value will likely be more volatile than the value of a more diversified fund.
**	The Fund Investment Category is used as a convenient way to describe Funds in this SAI and should not be deemed a description of the Fund’s principal investment strategies, which are described in the Fund’s prospectus.
***	Emerging Markets Consumer ETF may operate as a “non-diversified” Fund while the Dow Jones Emerging Markets Consumer Titans^TM Index is “non-diversified.”

ETF Overview

Each Index Fund offers and issues Shares at NAV only in large blocks, or aggregations, of Shares of a specified number of Shares, called Creation Units, generally in exchange for a basket of securities constituting the portfolio holdings of the Fund, together with the deposit of a specified cash payment or, in certain circumstances, for an all cash payment. Semi-Transparent Funds also offer and issue Shares at NAV only in Creation Units, however, Semi-Transparent Funds generally do so in-kind in exchange for the deposit or delivery of the securities and cash included in the Fund’s Tracking Basket. Semi-Transparent Funds reserve the right to permit or require Creation Units to be issued in exchange entirely or in part for cash. As a general matter, Semi-Transparent Funds expect to receive and redeem cash-in-lieu for Representative ETFs held in the Tracking Basket. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Funds. Shares of each Fund are listed and traded on the Exchange. Shares will trade on the Exchange at market prices that may be below, at, or above NAV.

Unlike conventional mutual funds, Shares are not individually redeemable securities. Rather, each Fund issues and redeems Shares on a continuous basis at NAV, only in Creation Units, which can vary in size (number of Shares) from Fund to Fund. A Fund’s Creation Unit size is disclosed in its prospectus. In the event of the liquidation of a Fund, the Trust may lower the number of Shares in a Creation Unit.

In the instance of creations and redemptions, Transaction Fees may be imposed. Such fees are limited in accordance with requirements of the SEC applicable to management investment companies offering redeemable securities. Some of the information contained in this SAI and the prospectuses – such as information about purchasing and redeeming Shares from a Fund and Transaction Fees – is not relevant to most retail investors.

Statement of Additional Information – [_________, 2022]

Table of Contents

Once created, Shares generally trade in the secondary market, at market prices that change throughout the day, in amounts less than a Creation Unit. For more information see the Purchase, Redemption and Pricing of Shares section. Investors purchasing Shares in the secondary market through a brokerage account or with the assistance of a broker may be subject to brokerage commissions and other charges.

Unlike index-based ETFs, including the Index Funds, Semi-Transparent Funds are actively managed and do not seek to track the performance of an index.

Semi-Transparent Funds operate pursuant to an exemptive order from the SEC and are not required to publicly disclose their complete portfolio holdings each Business Day. Instead, a Semi-Transparent Fund publishes each Business Day on its website a Tracking Basket, which is designed to closely track the daily performance of the Semi-Transparent Fund but is not the Semi-Transparent Fund’s actual portfolio. The Tracking Basket is comprised of: select recently disclosed portfolio holdings (Strategy Components); liquid ETFs that convey information about the types of instruments (that are not otherwise fully represented by the Strategy Components) in which the Semi-Transparent Fund invests (Representative ETFs); and cash and cash equivalents. The Tracking Basket often may include a significant percentage of the securities held in the Semi-Transparent Fund’s portfolio, but it will exclude (or modify the weightings of) certain securities held in the Semi-Transparent Fund’s portfolio, such as those securities that the Semi-Transparent Fund’s portfolio managers are actively looking to purchase or sell, or securities which, if disclosed, could increase the risk of front-running or free-riding.

A Semi-Transparent Fund also publishes each Business Day on its website its Tracking Basket Weight Overlap, which is the percentage weight overlap between the holdings of the prior Business Day’s Tracking Basket compared to the holdings of the Semi-Transparent Fund that formed the basis for the Semi-Transparent Fund’s calculation of its NAV at the end of the prior Business Day. The Tracking Basket Weight Overlap is designed to provide investors with an understanding of how similar the Tracking Basket is to the Semi-Transparent Fund’s actual portfolio in percentage terms.

A Semi-Transparent Fund’s Tracking Basket often may include a significant percentage of the securities held in the Semi-Transparent Fund’s portfolio, but it will exclude (or modify the weightings of) certain securities held in the Semi-Transparent Fund’s portfolio, such as those securities that the Semi-Transparent Fund’s portfolio managers are actively looking to purchase or sell, or securities which, if disclosed, could increase the risk of front-running or free-riding. For additional information regarding the Tracking Basket, see the section “How the Fund Differs from ETFs that Disclose their Portfolio Holdings Daily” in the Semi-Transparent Fund’s prospectus.

Exchange Listing and Trading

Shares of each Fund are listed and traded on the Exchange. Shares trade on the Exchange or in secondary markets at prices that may differ from their NAV or IIV, including because such prices may be affected by market forces (such as supply and demand for Shares). As is the case of other securities traded on an exchange, when you buy or sell Shares on the Exchange or in the secondary markets your broker or financial intermediary will normally charge you a commission or other transaction charges. These charges only apply to investors who buy and sell Shares of the Funds in secondary market transactions through brokers or other financial intermediaries on the Exchange and do not apply to investors such as market makers, large investors and institutions who wish to deal in Creation Units directly with a Fund. Further, the Trust reserves the right to adjust the price of Shares in the future to maintain convenient trading price ranges for investors (namely, to maintain a price per Share that is attractive to investors) by share splits or reverse share splits, which would have no effect on the NAV.

There can be no assurance that the Funds’ shares will continue to trade on the Exchange or that the requirements of the Exchange necessary to maintain the listing of Shares of each Fund will continue to be met. The Exchange may, but is not required to, remove the Shares of a Fund from listing if: (i) following the initial 12-month period beginning at the commencement of trading of a Fund, there are fewer than 50 beneficial owners of the Shares of the Fund for 30 or more consecutive trading days, (ii) For Index Funds, the value of the Index tracked by the Index Fund is no longer calculated or available, or (iii) such other event shall occur or condition exist that, in the opinion of the Exchange, makes further dealings on the Exchange inadvisable. The Exchange will remove the Shares of a Fund from listing and trading upon termination of a Fund.

In addition, for Semi-Transparent Funds, there may be circumstances where a security held in a Semi-Transparent Fund’s portfolio but not in its Tracking Basket does not have readily available market quotations. If the Investment Manager determines that such circumstance may affect the reliability of the Tracking Basket as an arbitrage vehicle, that information, along with the identity and weighting of that security in the Semi-Transparent Fund’s portfolio, will be publicly disclosed on the Semi-Transparent Fund’s website and the Investment Manager will assess appropriate remedial measures. In these circumstances, market participants may use this information to engage in certain predatory trading practices that may have the potential to harm the Semi-Transparent Fund and its shareholders. If securities representing 10% or more of the Semi-Transparent Fund’s portfolio do not have readily available market quotations, the Investment Manager will promptly request the Exchange to halt trading on the Semi-Transparent Fund, meaning that investors would not be able to trade Semi-Transparent Fund shares.

Table of Contents

The Funds are not sponsored, endorsed, sold or promoted by the Exchange. The Exchange makes no representation or warranty, express or implied, to the owners of Shares of the Funds or any member of the public regarding the advisability of investing in securities generally or in the Funds particularly or the ability of the Funds to achieve their objectives. The Exchange has no obligation or liability in connection with the administration, marketing or trading of the Funds.

Section 12(d)(1) Information

The Trusts and the Funds are part of the Columbia Funds Complex and are related for purposes of investor and investment services, as defined in Section 12(d)(1)(G) of the 1940 Act.

For purposes of the 1940 Act, shares are issued by a registered investment company and purchases of such shares by registered investment companies and companies relying on Section 3(c)(1) or 3(c)(7) of the 1940 Act are subject to the restrictions set forth in Section 12(d)(1) of the 1940 Act, except as permitted by an exemptive rule or order of the Securities and Exchange Commission (SEC). In October 2020, the SEC adopted Rule 12d1-4 relating to investments in other investment companies, which is effective on January 19, 2021 with a transition period until January 19, 2022 (the "Fund of Funds Rule"). The Funds are considering the impact of these regulatory changes.

Continuous Offering

The method by which Creation Units of Shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Units of Shares are issued and sold by each Trust on an ongoing basis, a ‘‘distribution,’’ as such term is used in the 1933 Act, may occur at any point. 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 and liability provisions of the 1933 Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent Shares and sells some or all of the Shares comprising such Creation Units directly to its 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. These examples should not be considered a complete description of all the activities that could lead to a categorization as an underwriter. A determination of whether a person is an underwriter for the purposes of the 1933 Act depends upon all the facts and circumstances pertaining to that person’s activities.

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, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3) of the 1933 Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. In addition, firms that incur a prospectus delivery obligation with respect to Shares of a Fund are reminded that, pursuant to Rule 153 under the 1933 Act, a prospectus delivery obligation under Section 5(b)(2) of the 1933 Act owed to a national securities exchange member in connection with a sale on the national securities exchange is satisfied by the fact that the Funds’ Prospectus is filed with the SEC. The prospectus delivery mechanism provided in Rule 153 is only available with respect to transactions on a national securities exchange and not with respect to ‘‘upstairs’’ transactions (i.e., the trading of securities that occurs within a broker-dealer firm or between two broker-dealers in the over-the-counter market).

FUNDAMENTAL AND NON-FUNDAMENTAL INVESTMENT POLICIES

The following discussion of “fundamental” and “non-fundamental” investment policies and limitations for each Fund supplements the discussion of investment policies in the Funds' prospectuses. A fundamental policy may be changed only with Board and shareholder approval. A non-fundamental policy may be changed only with Board approval and does not require shareholder approval.

Unless otherwise noted in a Fund’s prospectus or this SAI, whenever an investment policy or limitation states a maximum percentage of a Fund’s assets that may be invested in any security or other asset, or sets forth a policy regarding an investment standard, compliance with such percentage limitation or standard will be determined solely at the time of the Fund’s acquisition of such security or asset (Time of Purchase Standard). Thus, a Fund may continue to hold a security, even though it causes the Fund to exceed a percentage limitation or not meet a standard, because of post-acquisition changes, including fluctuation in the value of the Fund’s assets.

Fundamental Policies

The table below shows Fund-specific policies that may be changed only with a “vote of a majority of the outstanding voting securities” of the Fund, which means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of the Fund, or (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The table indicates whether or not a fund has a policy on a particular topic. A dash indicates that the Fund does not have a Fundamental policy on a particular topic. The specific policy is stated in the paragraphs that follow the table.

The Fund is ‘‘non-diversified’’ which means that the proportion of the Fund’s assets that may be invested in the securities of a single issuer is not limited by the 1940 Act. The Fund, however, intends to seek to qualify as a ‘‘regulated investment company’’ (‘‘RIC’’) for purposes of the Internal Revenue Code of 1986 (the ‘‘Code’’), which imposes diversification requirements on these Funds that are less restrictive than the requirements applicable to the ‘‘diversified’’ investment companies under the 1940 Act.

*	For purposes of applying the limitation set forth in its issuer diversification policy above, a Fund does not consider futures or swaps central counterparties, where the Fund has exposure to such central counterparties in the course of making investments in futures and securities, to be issuers.

†	For purposes of applying the limitation set forth in its issuer diversification policy, under certain circumstances, a Fund may treat an investment, if any, in a municipal bond refunded with escrowed U.S. Government securities as an investment in U.S. Government securities.

D.	Concentration*

D1 –	Except that a Fund may concentrate to approximately the same extent that its index concentrates in such particular industry or industries, the Fund will not purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (i) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States or any of their agencies, instrumentalities or political subdivisions; and (ii) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more investment companies or subsidiaries to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief. For purposes of determining whether a Fund is concentrated in an industry or group of industries, the Fund may concentrate its investment in the securities of companies engaged in a single industry or group of industries to approximately the same extent as its Index.
D2 –	The Fund may not invest 25% or more of the Fund’s net assets in securities of issuers in any one industry or group of industries (other than securities issued or guaranteed by the U.S. government or any of its agencies or instrumentalities or securities of other investment companies), except that a Fund may invest 25% or more of its net assets in securities of issuers in the same industry to approximately the same extent that the Fund’s corresponding index concentrates in the securities of a particular industry or group of industries. Accordingly, if the Fund’s corresponding index stops concentrating in the securities of a particular industry or group of industries, the Fund will also discontinue concentrating in such securities.
D3 –	Except that a Fund will be concentrated to approximately the same extent that its index concentrates in such particular industry or industries, the Fund will not purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (i) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States or any of their agencies, instrumentalities or political subdivisions; and (ii) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more investment companies or subsidiaries to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief. For purposes of determining whether a Fund is concentrated in an industry or group of industries, the Fund will concentrate its investment in the securities of companies engaged in a single industry or group of industries to approximately the same extent as its Index.

Table of Contents

D4 –

The Fund may not purchase the securities of any issuer if, as a result, less than 25% of the Fund’s total assets would be invested in the securities of issuers principally engaged in the semiconductor and semiconductor equipment industry, provided that (i) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States or any of their agencies, instrumentalities or political subdivisions; and (ii) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more investment companies or subsidiaries to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

For purposes of applying the limitation set forth in its concentration policy above, a Fund will generally use the industry classifications provided by the Global Industry Classification Standard (GICS) for classification of issuers of equity securities and the classifications provided by the Bloomberg U.S. Aggregate Bond Index for classification of issues of fixed-income securities. A Fund considers the concentration policies of any underlying funds in which it invests, and will consider the portfolio positions applying the Time of Purchase Standard, which in the case of unaffiliated underlying funds is based on portfolio information made publicly available by them. A Fund does not consider futures or swaps clearinghouses or securities clearinghouses, where the Fund has exposure to such clearinghouses in the course of making investments in futures and securities, to be part of any industry.

E.	Act as an underwriter

E1 –

The Fund will not underwrite any issue of securities issued by other persons within the meaning of the 1933 Act except when it might be deemed to be an underwriter either: (i) in connection with the disposition of a portfolio security; or (ii) in connection with the purchase of securities directly from the issuer where the Fund later resells such securities. This restriction shall not limit the Fund’s ability to invest in securities issued by other registered investment companies.

E2 –

The Fund may not act as an underwriter, except to the extent the Fund may be deemed to be an underwriter when disposing of securities it owns or when selling its own Shares.

Lending

F1 –

The Fund will not make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

F2 –

The Fund may not make loans if, as a result, more than 33¹⁄3% of its total assets would be lent to other persons, including other investment companies to the extent permitted by the 1940 Act or any rules, exemptions or interpretations thereunder which may be adopted, granted or issued by the SEC. This limitation does not apply to (i) the lending of portfolio securities; (ii) the purchase of debt securities, other debt instruments, loan participations and/or engaging in direct corporate loans in accordance with its investment goals and policies; and (iii) repurchase agreements to the extent the entry into a repurchase agreement is deemed to be a loan.

Borrowing

G1 –	The Fund will not borrow money except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.
G2 –	The Fund may not borrow money, except to the extent permitted by the 1940 Act, or any rules, exemptions or interpretations thereunder that may be adopted, granted or issued by the SEC.

H.	Issue senior securities

H1 –	The Fund will not issue senior securities, except as permitted under the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.
H2 –	The Fund may not issue senior securities, except to the extent permitted by the 1940 Act or any rules, exemptions or interpretations thereunder that may be adopted, granted or issued by the SEC.

Non-fundamental Policies

The following non-fundamental policies may be changed by the Board at any time and may be in addition to those described in the Funds' prospectus.

Investment in Illiquid Investments

No Fund may acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid investments that are assets. For these purposes, an “illiquid investment” means any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment.

Statement of Additional Information – [_________, 2022]

Table of Contents

Investment in Other Investment Companies

The Funds may not purchase securities of other investment companies except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

Names Rule Policy

To the extent a Fund is subject to Rule 35d-1 under the 1940 Act (the Names Rule) and does not otherwise have a fundamental policy in place to comply with the Names Rule, such Fund has adopted the following non-fundamental policy: Shareholders will receive at least 60 days’ notice of any change to the Fund’s investment objective or principal investment strategies made in order to comply with the Names Rule. The notice will be provided in plain English in a separate written document, and will contain the following prominent statement or similar statement in bold-face type: “Important Notice Regarding Change in Investment Policy.” This statement will appear on both the notice and the envelope in which it is delivered, unless it is delivered separately from other communications to investors, in which case the statement will appear either on the notice or the envelope in which the notice is delivered. A Fund subject to a fundamental policy in place to comply with the Names Rule will disclose in the More Information About the Fund section of its prospectus that its 80% policy cannot be changed without shareholder approval.

To the extent that the Fund counts derivatives towards compliance with its 80% policy, such instruments will be valued based on their market value or fair value (determined in accordance with the Fund’s valuation procedures) or, when the adviser determines that the notional value of such instruments is a more appropriate measure of the Fund’s exposure to economic characteristics of investments that are consistent with the Fund’s 80% policy, at such notional value.

For each Index Fund:

Fund Index

Each Index Fund seeks investment results that, before fees and expenses, closely correspond to the performance of its Index as disclosed in the Index Fund’s prospectus. Several factors may affect a Fund’s ability to achieve this correlation, including, but not limited to: (1) a Fund’s expenses, including brokerage commissions (which may be increased by high portfolio turnover) and the cost of the investment techniques employed by that Fund; (2) a Fund’s holding of less than all of the securities in the Index, including as part of a ‘‘representative sampling’’ strategy, and holding securities not included in the Index; (3) an imperfect correlation between the performance of a Fund’s investments and those of its Index; (4) bid-ask spreads (the effect of which may be increased by portfolio turnover); (5) holding instruments traded in a market that has become illiquid or disrupted; (6) a Fund’s Share prices being rounded to the nearest cent; (7) changes to the Index that are not disseminated in advance; (8) the need to conform a Fund’s portfolio holdings to comply with investment restrictions or policies, or regulatory or tax law requirements; (9) early and unanticipated closings of the markets on which the holdings of a Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions; and (10) a Fund’s holdings of cash or cash equivalents, or otherwise not being fully invested in securities of its Index. While close tracking of any Fund to its Index may be achieved on any single trading day, over time the cumulative percentage increase or decrease in the NAV of the Shares of a Fund may diverge significantly from the cumulative percentage decrease or increase in the Index due to a compounding effect.

Each of the Index Funds may consider changing its current Index at any time, including if, for example: the Index becomes unavailable; the Board believes that the current Index no longer serves the shareholder investment needs or that another index may better serve their needs; or the financial or economic environment makes it difficult for the Fund’s investment results to correspond sufficiently to the current Index. If a Fund determines to change its Index, it will assess the appropriateness of the Fund's current name in light of the new index.

Fundamental securities analysis is not used by the Investment Manager in seeking to correlate an Index Fund’s investment returns with its Index. Rather, the Investment Manager uses a passive (or indexing) approach to determine the investments an Index Fund makes and techniques it employs. While the Investment Manager attempts to minimize any “tracking error,” certain factors tend to cause an Index Fund’s investment results to vary from a perfect correlation to its Index, as applicable. See About Fund Investments – Information Regarding Risks – Correlation/Tracking Error Risk below for additional details.

For Semi-Transparent Funds:

For Semi-Transparent Funds, the Investment Manager applies fundamental securities analysis in seeking to achieve the Semi-Transparent Fund’s investment objective. A Semi-Transparent Fund does not seek to correlate its investment returns with those of an index.

Additional Information About Concentration

Index rebalancings or other Index changes, or corporate actions relating to investments held by an Index Fund can subsequently cause the Fund to be concentrated when the Index is not, in which case the Fund will seek to exit the concentration as soon as reasonably practicable. The Fund may indirectly concentrate in a particular industry or group of industries through investments in underlying funds.

Table of Contents

For each of Sustainable International Equity Income ETF and Sustainable U.S. Equity Income ETF, the Fund may not:

1.	Borrow an amount exceeding 10% of the value of its net assets and may borrow only on a temporary basis.

Summary of 1940 Act Restrictions on Certain Activities

Certain of the Fund’s fundamental and, if any, non-fundamental policies set forth above prohibit transactions “except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.” The following discussion summarizes the flexibility that the Fund currently gains from these exceptions. To the extent the 1940 Act or the rules and regulations thereunder may, in the future, be amended to provide greater flexibility, or to the extent the SEC may in the future grant exemptive relief providing greater flexibility, the Fund will be able to use that flexibility without seeking shareholder approval of its fundamental policies.

Borrowing money – The 1940 Act permits a Fund to borrow up to 33¹⁄3% of its total assets (including the amounts borrowed) from banks, plus an additional 5% of its total assets for temporary purposes, which may be borrowed from banks or other sources. The exception in the fundamental policy allows the Funds to borrow money subject to these conditions. Compliance with this limitation is not measured under the Time of Purchase Standard (meaning, a Fund may not exceed these thresholds including if, after borrowing, the Fund’s net assets decrease due to market fluctuations).

Buy or sell physical commodities – The 1940 Act does not directly limit a Fund’s ability to invest directly in physical commodities. However, a Fund’s direct and indirect investments in physical commodities may be limited by the Fund’s intention to qualify as a RIC, and can limit the Fund’s ability to so qualify. One of the requirements for favorable tax treatment as a RIC under the Code is that a Fund derive at least 90 percent of its gross income from certain qualifying sources of income. Income and gains from direct commodities investments, and from certain indirect investments therein, do not constitute qualifying income for this purpose. A Fund that qualifies for an exclusion from the definition of a commodity pool under the CEA and has on file a notice of exclusion under CFTC Rule 4.5 is limited in its ability to use certain financial instruments regulated under the CEA (“commodity interests”).

Investing in other investment companies – The 1940 Act, in summary, provides that a fund generally may not: (i) purchase more than 3% of the outstanding voting stock of another investment company; (ii) purchase securities issued by another investment company in an amount representing more than 5% of the investing fund’s total assets; or (iii) purchase securities issued by investment companies that in the aggregate represent more than 10% of the acquiring fund’s total assets (the “Statutory Limits”). Affiliated funds-of-funds (i.e., those funds that invest in other funds within the same fund family), with respect to investments in such affiliated underlying funds, are not subject to the Statutory Limits and, therefore, may invest in affiliated underlying funds without restriction. Currently, a fund-of-funds may also invest its assets in unaffiliated funds, but generally may not purchase more than 3% of the outstanding voting stock of any one unaffiliated fund. Additionally, certain exceptions to these limitations apply to investments in money market open-end funds. If shares of the Fund are purchased by an affiliated fund beyond the Statutory Limits in reliance on Section 12(d)(1)(G) of the 1940 Act, for so long as shares of the Fund are held by such other affiliated fund beyond the Statutory Limits, the Fund will not purchase securities of a registered open-end investment company or registered unit investment trust in reliance on Section 12(d)(1)(F) or Section 12(d)(1)(G) of the 1940 Act. In October 2020, the SEC adopted certain regulatory changes and took other actions related to the ability of an investment company to invest in the securities of another investment company. These changes include, among other things, the rescission of certain SEC exemptive orders and rules permitting investments in excess of the Statutory Limits and the withdrawal of certain related SEC staff no-action letters, and the adoption of Rule 12d1-4 under the 1940 Act. Rule 12d1-4, which became effective on January 19, 2021, permits the Funds to invest in other investment companies beyond the Statutory Limits, subject to certain conditions. After January 19, 2022, if shares of the Fund are purchased by another fund beyond the Statutory Limits, and the Fund purchases shares of another investment company, the Fund will not be able to make new investments in other funds, including private funds exempt from the definition of “investment company” under the 1940 Act by Sections 3(c)(1) or 3(c)(7) thereof, if, as a result of such investment, more than 10% of the Fund’s assets would be invested in other funds. In addition, after January 19, 2022, an affiliated fund-of-funds’ investment in unaffiliated funds may be made only pursuant to Rule 12d1-4.

Issuing senior securities – A “senior security” is an obligation with respect to the earnings or assets of a company that takes precedence over the claims of that company’s common stock with respect to the same earnings or assets. The 1940 Act prohibits an open-end fund from issuing senior securities other than certain borrowings from a bank, but SEC staff interpretations allow a Fund to engage in certain types of transactions that otherwise might raise senior security concerns (such as short sales, buying and selling financial futures contracts and other derivative instruments and selling put and call options), provided that the Fund segregates or designates on the Fund’s books and records liquid assets, or, as permitted in accordance with SEC staff interpretations, otherwise covers the transaction with offsetting portfolio securities, in amounts sufficient to offset any liability associated with the transaction. The exception in the fundamental policy allows the Fund to operate in reliance upon these staff interpretations.

ABOUT FUND INVESTMENTS

Each Fund’s investment objective, principal investment strategies and related principal risks are discussed in each Fund’s prospectus. Each Fund’s prospectus identifies the types of securities in which the Fund invests principally and summarizes the principal risks to the Fund’s portfolio as a whole associated with such investments. Unless otherwise indicated in the prospectus or this SAI, the investment objective and policies of a Fund may be changed without shareholder approval.

To the extent that a type of security identified in the table below for a Fund is not described in the Fund’s prospectus (or as a sub-category of such security type in this SAI), the Fund may invest in such security type as part of its non-principal investment strategies.

Information about individual types of securities (including certain of their associated risks) in which the Funds may invest is set forth below. Each Fund may invest in securities listed below unless prohibited by its fundamental and non-fundamental investment policies or as otherwise noted in this SAI. The information in the table below does not describe every type of investment, technique or risk to which a Fund may be exposed.

Certain Investment Activity Limits. The overall investment and other activities of the Investment Manager and its affiliates may limit the investment opportunities for each Fund in certain markets, industries or transactions or in individual issuers where limitations are imposed upon the aggregate amount of investment by the Funds and other accounts managed by the Investment Manager and accounts of its affiliates (collectively, affiliated investors). From time to time, each Fund’s activities also may be restricted because of regulatory restrictions applicable to the Investment Manager and its affiliates and/or because of their internal policies. See Investment Management and Other Services – Other Roles and Relationships of Ameriprise Financial and its Affiliates – Certain Conflicts of Interest.

Temporary Defensive Positions. A Semi-Transparent Fund may from time to time take temporary defensive investment positions that may be inconsistent with the Fund’s principal investment strategies in attempting to respond to adverse market, economic, political, social or other conditions, including, without limitation investing some or all of its assets in money market instruments or shares of affiliated or unaffiliated government money market funds or holding some or all of its assets in cash or cash equivalents. The Fund may take such defensive investment positions for as long a period as deemed necessary.

Other Strategic and Investment Measures. A Semi-Transparent Fund may also from time to time take temporary portfolio positions that may or may not be consistent with the Fund’s principal investment strategies in attempting to respond to adverse market, economic, political, social or other conditions, including, without limitation, investing in exchange-traded futures (a derivative) in seeking to reduce investment exposure, or in seeking to achieve indirect investment exposure, to a sector, country, region or currency where the Investment Manager (or Fund subadviser, if applicable) believes such defensive positioning is appropriate. A Semi-Transparent Fund may do so without limit and for as long a period as deemed necessary, when the Investment Manager or the Fund’s subadviser, if applicable: (i) believes that market conditions are not favorable for profitable investing or to avoid losses, (ii) is unable to locate favorable investment opportunities; or (iii) determines that a temporary defensive position is advisable or necessary in order to meet anticipated redemption requests, or for other reasons. While the Fund is so positioned, derivatives could comprise a substantial portion of the Fund’s investments and the Fund may not achieve its investment objective. Investing in this manner may adversely affect Fund performance. During these times, the portfolio managers may make frequent portfolio holding changes, which could result in increased trading expenses and decreased Fund performance.

Equity Funds and Fixed Income Funds that are Semi-Transparent Funds are permitted to invest only in other ETFs, exchange-traded notes, exchange-traded common stocks (other than “penny stocks,” as defined by Rule 3a51-1 under the Exchange Act), common stocks listed on a foreign exchange that trade on such exchange contemporaneously with the Shares, exchange-traded preferred stocks, exchange-traded American Depositary Receipts (ADRs), exchange-traded real estate investment trusts, exchange-traded commodity pools, exchange-traded metals trusts, exchange-traded currency trusts, and exchange-traded futures that trade contemporaneously with the Shares, as well as cash and cash equivalents (with cash equivalents being short-term U.S. Treasury securities, government money market funds, and repurchase agreements).

(a)	Each series of CET II may invest a portion of its assets, for cash management purposes, in liquid, high-quality, short-term debt securities (including repurchase agreements) of corporations, the U.S. government and its agencies and instrumentalities, and banks and finance companies.

(b)	The Funds may engage in short sales in accordance with their investment objective and subject to any Fundamental or Non-Fundamental Investment policy.

Asset-Backed Securities

Asset-backed securities represent interests in, or debt instruments that are backed by, pools of various types of assets that generate cash payments generally over fixed periods of time, such as, among others, motor vehicle installment sales, contracts, installment loan contracts, leases of various types of real and personal property, and receivables from revolving (credit card) agreements. Such securities entitle the security holders to receive distributions (i.e., principal and interest) that are tied to the payments made by the borrower on the underlying assets (less fees paid to the originator, servicer, or other parties, and fees paid for credit enhancement), so that the payments made on the underlying assets effectively pass through to such security holders. Asset-backed securities typically are created by an originator of loans or owner of accounts receivable that sells such underlying

Statement of Additional Information – [_________, 2022]

Table of Contents

assets to a special purpose entity in a process called a securitization. The special purpose entity issues securities that are backed by the payments on the underlying assets, and have a minimum denomination and specific term. Asset-backed securities may be structured as fixed-, variable- or floating-rate obligations or as zero-coupon, pay-in-kind and step-coupon securities and may be privately placed or publicly offered. Collateralized loan obligations (CLOs) and collateralized debt obligations (CDOs) are examples of asset-backed securities. See Types of Investments – Variable- and Floating-Rate Obligations, – Debt Obligations – Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and – Private Placement and Other Restricted Securities for more information.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with asset-backed securities include: Credit Risk, Interest Rate Risk, Liquidity Risk and Prepayment and Extension Risk.

Bank Obligations (Domestic and Foreign)

Bank obligations include certificates of deposit, bankers’ acceptances, time deposits and promissory notes that earn a specified rate of return and may be issued by (i) a domestic branch of a domestic bank, (ii) a foreign branch of a domestic bank, (iii) a domestic branch of a foreign bank or (iv) a foreign branch of a foreign bank. Bank obligations may be structured as fixed-, variable- or floating-rate obligations. See Types of Investments – Variable- and Floating-Rate Obligations for more information.

Certificates of deposit, or so-called CDs, typically are interest-bearing debt instruments issued by banks and have maturities ranging from a few weeks to several years. Yankee dollar certificates of deposit are negotiable CDs issued in the United States by branches and agencies of foreign banks. Eurodollar certificates of deposit are CDs issued by foreign banks with interest and principal paid in U.S. dollars. Eurodollar and Yankee Dollar CDs typically have maturities of less than two years and have interest rates that typically are pegged to a reference rate, such as LIBOR or SOFR. Bankers’ acceptances are time drafts drawn on and accepted by banks, are a customary means of effecting payment for merchandise sold in import-export transactions and are a general source of financing. A time deposit can be either a savings account or CD that is an obligation of a financial institution for a fixed term. Typically, there are penalties for early withdrawals of time deposits. Promissory notes are written commitments of the maker to pay the payee a specified sum of money either on demand or at a fixed or determinable future date, with or without interest.

Bank investment contracts are issued by banks. Pursuant to such contracts, a Fund may make cash contributions to a deposit fund of a bank. The bank then credits to the Fund payments at floating or fixed interest rates. A Fund also may hold funds on deposit with its custodian for temporary purposes.

Certain bank obligations, such as some CDs, are insured by the FDIC up to certain specified limits. Many other bank obligations, however, are neither guaranteed nor insured by the FDIC or the U.S. Government. These bank obligations are “backed” only by the creditworthiness of the issuing bank or parent financial institution. Domestic and foreign banks are subject to different governmental regulation. Accordingly, certain obligations of foreign banks, including Eurodollar and Yankee dollar obligations, involve different and/or heightened investment risks than those affecting obligations of domestic banks, including, among others, the possibilities that: (i) their liquidity could be impaired because of political or economic developments; (ii) the obligations may be less marketable than comparable obligations of domestic banks; (iii) a foreign jurisdiction might impose withholding and other taxes at high levels on interest income; (iv) foreign deposits may be seized or nationalized; (v) foreign governmental restrictions such as exchange controls may be imposed, which could adversely affect the payment of principal and/or interest on those obligations; (vi) there may be less publicly available information concerning foreign banks issuing the obligations; and (vii) the reserve requirements and accounting, auditing and financial reporting standards, practices and requirements applicable to foreign banks may differ (including, less stringent) from those applicable to domestic banks. Foreign banks generally are not subject to examination by any U.S. Government agency or instrumentality. See Types of Investments – Foreign Securities.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with bank obligations include: Counterparty Risk, Credit Risk, Interest Rate Risk, Issuer Risk, Liquidity Risk, and Prepayment and Extension Risk.

Collateralized Bond Obligations

Collateralized bond obligations (CBOs) are investment grade bonds backed by a pool of bonds, which may include junk bonds (which are considered speculative investments). CBOs are similar in concept to collateralized mortgage obligations (CMOs), but differ in that CBOs represent different degrees of credit quality rather than different maturities. (See Types of Investments – Mortgage-Backed Securities and – Asset-Backed Securities.) CBOs are often privately offered and sold, and thus not registered under the federal securities laws.

Underwriters of CBOs package a large and diversified pool of high-risk, high-yield junk bonds, which is then structured into “tranches.” Typically, the first tranche represents a senior claim on collateral and pays the lowest interest rate; the second tranche is junior to the first tranche and therefore subject to greater risk and pays a higher rate; the third tranche is junior to both the first

Statement of Additional Information – [_________, 2022]

Table of Contents

and second tranche, represents the lowest credit quality and instead of receiving a fixed interest rate receives the residual interest payments — money that is left over after the higher tranches have been paid. CBOs, like CMOs, are substantially overcollateralized and this, plus the diversification of the pool backing them, may earn certain of the tranches investment-grade bond ratings. Holders of third-tranche CBOs stand to earn higher or lower yields depending on the rate of defaults in the collateral pool. See Types of Investments – High-Yield Securities.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with CBOs include: Credit Risk, Interest Rate Risk, Liquidity Risk, High-Yield Securities Risk and Prepayment and Extension Risk.

Commercial Paper

Commercial paper is a short-term debt obligation, usually sold on a discount basis, with a maturity ranging from 2 to 270 days issued by banks, corporations and other borrowers. It is sold to investors with temporary idle cash as a way to increase returns on a short-term basis. These instruments are generally unsecured, which increases the credit risk associated with this type of investment. See Types of Investments — Debt Obligations and — Illiquid Investments. See Appendix A for a discussion of securities ratings.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with commercial paper include: Credit Risk and Liquidity Risk.

Common Stock

Common stock represents a unit of equity ownership of a corporation. Owners typically are entitled to vote on the selection of directors and other important corporate governance matters, and to receive dividend payments, if any, on their holdings. However, ownership of common stock does not entitle owners to participate in the day-to-day operations of the corporation. Common stocks of domestic and foreign public corporations can be listed, and their shares traded, on domestic stock exchanges, such as the NYSE or the NASDAQ Stock Market. Domestic and foreign corporations also may have their shares traded on foreign exchanges, such as the London Stock Exchange or Tokyo Stock Exchange. See Types of Investments – Foreign Securities. Common stock may be privately placed or publicly offered. The price of common stock is generally determined by corporate earnings, type of products or services offered, projected growth rates, experience of management, liquidity, and market conditions generally. In the event that a corporation declares bankruptcy or is liquidated, the claims of secured and unsecured creditors and owners of bonds and preferred stock take precedence over the claims of those who own common stock. See Types of Investments – Private Placement and Other Restricted Securities, – Preferred Stock and – Convertible Securities for more information.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with common stock include: Issuer Risk and Market Risk.

Convertible Securities

Convertible securities include bonds, debentures, notes, preferred stocks or other securities that may be converted or exchanged (by the holder or by the issuer) into shares of the underlying common stock (or cash or securities of equivalent value) at a stated exchange ratio or predetermined price (the conversion price). As such, convertible securities combine the investment characteristics of debt securities and equity securities. A holder of convertible securities is entitled to receive the income of a bond, debenture or note or the dividend of a preferred stock until the conversion privilege is exercised. The market value of convertible securities generally is a function of, among other factors, interest rates, the rates of return of similar nonconvertible securities and the financial strength of the issuer. The market value of convertible securities tends to decline as interest rates rise and, conversely, to rise as interest rates decline. However, a convertible security’s market value tends to reflect the market price of the common stock of the issuing company when that stock price approaches or is greater than its conversion price. As the market price of the underlying common stock declines, the price of the convertible security tends to be influenced more by the rate of return of the convertible security. Because both interest rate and common stock’s market movements can influence their value, convertible securities generally are not as sensitive to changes in interest rates as similar non-convertible debt securities nor generally as sensitive to changes in share price as the underlying common stock. Convertible securities may be structured as fixed-, variable- or floating-rate obligations or as zero-coupon, pay-in-kind and step-coupon securities and may be privately placed or publicly offered. See Types of Investments — Variable- and Floating-Rate Obligations, — Debt Obligations - Zero-Coupon, Pay-in-Kind and Step-Coupon Securities, — Common Stock, — Corporate Debt Securities and — Private Placement and Other Restricted Securities for more information.

Certain convertible securities may have a mandatory conversion feature, pursuant to which the securities convert automatically into common stock or other equity securities (of the same or a different issuer) at a specified date and at a specified exchange ratio. Certain convertible securities may be convertible at the option of the issuer, which may require a holder to convert the security into the underlying common stock, even at times when the value of the underlying common stock or other equity security has declined substantially. In addition, some convertible securities may be rated below investment grade or may not be

rated and, therefore, may be considered speculative investments. Companies that issue convertible securities frequently are small- and mid-capitalization companies and, accordingly, carry the risks associated with such companies. In addition, the credit rating of a company’s convertible securities generally is lower than that of its conventional debt securities. Convertible securities are senior to equity securities and have a claim to the assets of an issuer prior to the holders of the issuer’s common stock in the event of liquidation but generally are subordinate to similar non-convertible debt securities of the same issuer. Some convertible securities are particularly sensitive to changes in interest rates when their predetermined conversion price is much higher than the price for the issuing company’s common stock.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with convertible securities include: Convertible Securities Risk, Interest Rate Risk, Issuer Risk, Market Risk, Prepayment and Extension Risk, and Reinvestment Risk.

Corporate Debt Securities

Corporate debt securities are long and short term fixed income securities typically issued by businesses to finance their operations. Corporate debt securities are issued by public or private companies, as distinct from debt securities issued by a government or its agencies. The issuer of a corporate debt security often has a contractual obligation to pay interest at a stated rate on specific dates and to repay principal periodically or on a specified maturity date. Corporate debt securities typically have four distinguishing features: (1) they are taxable; (2) they have a par value of $1,000; (3) they have a term maturity, which means they come due at a specified time period; and (4) many are traded on major securities exchanges. Notes, bonds, debentures and commercial paper are the most common types of corporate debt securities, with the primary difference being their interest rates, maturity dates and secured or unsecured status. Commercial paper has the shortest term and usually is unsecured, as are debentures. The broad category of corporate debt securities includes debt issued by domestic or foreign companies of all kinds, including those with small-, mid- and large-capitalizations. The category also includes bank loans, as well as assignments, participations and other interests in bank loans. Corporate debt securities may be rated investment grade or below investment grade and may be structured as fixed-, variable or floating-rate obligations or as zero-coupon, pay-in-kind and step-coupon securities and may be privately placed or publicly offered. They may also be senior or subordinated obligations. See Appendix A for a discussion of securities ratings. See Types of Investments — Variable- and Floating-Rate Obligations, — Private Placement and Other Restricted Securities, — Debt Obligations, — Commercial Paper and — High-Yield Securities for more information.

Extendible commercial notes (ECNs) are very similar to commercial paper except that, with ECNs, the issuer has the option to extend the notes’ maturity. ECNs are issued at a discount rate, with an initial redemption of not more than 90 days from the date of issue. If ECNs are not redeemed by the issuer on the initial redemption date, the issuer will pay a premium (step-up) rate based on the ECN’s credit rating at the time.

Because of the wide range of types and maturities of corporate debt securities, as well as the range of creditworthiness of issuers, corporate debt securities can have widely varying risk/return profiles. For example, commercial paper issued by a large established domestic corporation that is rated by an NRSRO as investment grade may have a relatively modest return on principal but present relatively limited risk. On the other hand, a long-term corporate note issued, for example, by a small foreign corporation from an emerging market country that has not been rated by an NRSRO may have the potential for relatively large returns on principal but carries a relatively high degree of risk.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with corporate debt securities include: Credit Risk, Interest Rate Risk, Issuer Risk, High-Yield Securities Risk, Prepayment and Extension Risk and Reinvestment Risk.

Custody Receipts and Trust Certificates

Custody receipts and trust certificates are derivative products that evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing interests in those securities. The sponsor generally then will sell the custody receipts or trust certificates in negotiated transactions at varying prices. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with custody receipts and trust certificates include: Liquidity Risk and Counterparty Risk. In addition, custody receipts and trust certificates generally are subject to the same risks as the securities evidenced by the receipts or certificates.

Debt Obligations

Many different types of debt obligations exist (for example, bills, bonds, and notes). Issuers of debt obligations have a contractual obligation to pay interest at a fixed, variable or floating rate on specified dates and to repay principal by a specified maturity date. Certain debt obligations (usually intermediate and long-term bonds) have provisions that allow the issuer to redeem or “call” a bond before its maturity. Issuers are most likely to call these securities during periods of falling interest rates. When this happens, an investor may have to replace these securities with lower yielding securities, which could result in a lower return.

The market value of debt obligations is affected primarily by changes in prevailing interest rates and the issuer’s perceived ability to repay the debt. The market value of a debt obligation generally reacts inversely to interest rate changes. When prevailing interest rates decline, the market value of the bond usually rises, and when prevailing interest rates rise, the market value of the bond usually declines.

In general, the longer the maturity of a debt obligation, the higher its yield and the greater the sensitivity to changes in interest rates. Conversely, the shorter the maturity, the lower the yield and the lower the sensitivity to changes in interest rates.

As noted, the values of debt obligations also may be affected by changes in the credit rating or financial condition of their issuers. Generally, the lower the quality rating of a security, the higher the degree of risk as to the payment of interest and return of principal. To compensate investors for taking on such increased risk, those issuers deemed to be less creditworthy generally must offer their investors higher interest rates than do issuers with better credit ratings. See Types of Investments — Corporate Debt Securities, — High-Yield Securities and — Preferred Stock - Trust-Preferred Securities for information.

Event-Linked Instruments/Catastrophe Bonds. A Fund may obtain event-linked exposure by investing in “event-linked bonds” or “event-linked swaps” or by implementing “event-linked strategies.” Event-linked exposure results in gains or losses that typically are contingent on, or formulaically related to, defined trigger events. Examples of trigger events include hurricanes, earthquakes, weather-related phenomena or statistics relating to such events. Some event-linked bonds are commonly referred to as “catastrophe bonds.” If a trigger event occurs, the principal amount of the bond is reduced (potentially to zero), and a Fund may lose all or a portion of its entire principal invested in the bond or the entire notional amount on a swap.

Stripped Securities. Stripped securities are the separate income or principal payments of a debt security and evidence ownership in either the future interest or principal payments on an instrument. There are many different types and variations of stripped securities. For example, Separate Trading of Registered Interest and Principal Securities (STRIPS) can be component parts of a U.S. Treasury security where the principal and interest components are traded independently through DTC, a clearing agency registered pursuant to Section 17A of the 1934 Act and created to hold securities for its participants, and to facilitate the clearance and settlement of securities transactions between participants through electronic computerized book-entries, thereby eliminating the need for physical movement of certificates. Treasury Investor Growth Receipts (TIGERs) are U.S. Treasury securities stripped by brokers. Stripped mortgage-backed securities, (SMBS) also can be issued by the U.S. Government or its agencies. Stripped securities may be structured as fixed-, variable- or floating-rate obligations.

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 assets. Common types of SMBS will be structured so that one class receives some of the interest and most of the principal from the mortgage-backed assets, while another class receives most of the interest and the remainder of the principal.

See Types of Investments – Mortgage-Backed Securities, – Variable- and Floating-Rate Obligations and – U.S. Government and Related Obligations for more information.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with stripped securities include: Credit Risk, Interest Rate Risk, Liquidity Risk, Prepayment and Extension Risk and Stripped Securities Risk

When-Issued, Delayed Delivery and Forward Commitment Transactions. When-issued, delayed delivery and forward commitment transactions involve the purchase or sale of securities by a Fund, with payment and delivery taking place in the future after the customary settlement period for that type of security. Normally, the settlement date occurs within 45 days of the purchase although in some cases settlement may take longer. The investor does not pay for the securities or receive dividends or interest on them until the contractual settlement date. When engaging in when-issued, delayed delivery and forward commitment transactions, a Fund typically will designate liquid assets in an amount equal to or greater than the purchase price. The payment obligation and, if applicable, the interest rate that will be received on the securities, are fixed at the time that a Fund agrees to purchase the securities. A Fund generally will enter into when-issued, delayed delivery and forward commitment transactions only with the intention of completing such transactions.

However, a Fund’s portfolio manager may determine not to complete a transaction if he or she deems it appropriate to close out the transaction prior to its completion. In such cases, a Fund may realize short-term gains or losses. See Types of Investments — Asset-Backed Securities and — Mortgage-Backed Securities for more information.

Statement of Additional Information – [_________, 2022]

Table of Contents

To Be Announced Securities (“TBAs”). As with other delayed delivery transactions, a seller agrees to issue a TBA security at a future date. However, the seller does not specify the particular securities to be delivered. Instead, the Fund agrees to accept any security that meets specified terms. For example, in a TBA mortgage-backed security transaction, the Fund and the seller would agree upon the issuer, interest rate and terms of the underlying mortgages. The seller would not identify the specific underlying mortgages until it issues the security. TBA mortgage-backed securities increase market risks because the underlying mortgages may be less favorable than anticipated by the Fund. See Types of Investments — Asset-Backed Securities and — Mortgage-Backed Securities for more information. In order to better define contractual rights and to secure rights that will help a Fund mitigate their counterparty risk, TBA transactions may be entered into by a Fund under Master Securities Forward Transaction Agreements (each, an “MSFTA”). An MSFTA typically contains, among other things, collateral posting terms and netting provisions in the event of default and/or termination event. The collateral requirements are typically calculated by netting the mark-to-market amount for each transaction under such agreement and comparing that amount to the value of the collateral currently pledged by a fund and the counterparty. To the extent amounts due to a Fund are not fully collateralized, contractually or otherwise, a Fund bears the risk of loss from counterparty non-performance.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with when-issued, delayed delivery and forward commitment transactions include: Counterparty Risk, Credit Risk and Market Risk.

Zero-Coupon, Pay-in-Kind and Step-Coupon Securities. Zero-coupon, pay-in-kind and step-coupon securities are types of debt instruments that do not necessarily make payments of interest in fixed amounts or at fixed intervals. Asset-backed securities, convertible securities, corporate debt securities, foreign securities, high-yield securities, mortgage-backed securities, municipal securities, participation interests, stripped securities, U.S. Government and related obligations and other types of debt instruments may be structured as zero-coupon, pay-in-kind and step-coupon securities.

Zero-coupon securities do not pay interest on a current basis but instead accrue interest over the life of the security. These securities include, among others, zero-coupon bonds, which either may be issued at a discount by a corporation or government entity or may be created by a brokerage firm when it strips the coupons from a bond or note and then sells the bond or note and the coupon separately. This technique is used frequently with U.S. Treasury bonds, and zero-coupon securities are marketed under such names as CATS (Certificate of Accrual on Treasury Securities), TIGERs or STRIPS. Zero-coupon bonds also are issued by municipalities. Buying a municipal zero-coupon bond frees its purchaser of the obligation to pay regular federal income tax on imputed interest, since the interest is exempt for regular federal income tax purposes. Zero-coupon certificates of deposit and zero-coupon mortgages are generally structured in the same fashion as zero-coupon bonds; the certificate of deposit holder or mortgage holder receives face value at maturity and no payments until then.

Pay-in-kind securities normally give the issuer an option to pay cash at a coupon payment date or to give the holder of the security a similar security with the same coupon rate and a face value equal to the amount of the coupon payment that would have been made.

Step-coupon securities trade at a discount from their face value and pay coupon interest that gradually increases over time. The coupon rate is paid according to a schedule for a series of periods, typically lower for an initial period and then increasing to a higher coupon rate thereafter. The discount from the face amount or par value depends on the time remaining until cash payments begin, prevailing interest rates, liquidity of the security and the perceived credit quality of the issue.

Zero-coupon, pay-in-kind and step-coupon securities holders generally have substantially all the rights and privileges of holders of the underlying coupon obligations or principal obligations. Holders of these securities typically have the right upon default on the underlying coupon obligations or principal obligations to proceed directly and individually against the issuer and are not required to act in concert with other holders of such securities.

See Appendix A for a discussion of securities ratings. See Types of Investments — Asset-Backed Securities and — Mortgage-Backed Securities for more information.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with zero-coupon, step-coupon, and pay-in-kind securities include: Credit Risk, Interest Rate Risk and Zero-Coupon Bonds Risk.

Determining Investment Grade for Purposes of Investment Policies. Unless otherwise stated in the Fund’s prospectus, when determining, under a Fund’s investment policies, whether a debt instrument is investment grade or below investment grade for purposes of purchase by the Fund, the Fund will apply a particular credit quality rating methodology, as described within the Fund’s shareholder reports, when available. These methodologies typically make use of credit quality ratings assigned by a third-party rating agency or agencies, when available. Credit quality ratings assigned by a rating agency are subjective opinions, not statements of fact, and are subject to change, including daily. Credit quality ratings apply to the Fund’s debt instrument investments and not the Fund itself.

Ratings limitations under a Fund’s investment policies are applied at the time of purchase by a Fund. Subsequent to purchase, a debt instrument may cease to be rated by a rating agency or its rating may be reduced by a rating agency(ies) below the minimum required for purchase by a Fund. Neither event will require the sale of such debt instrument, but it may be a factor in

considering whether to continue to hold the instrument. Unless otherwise stated in a Fund’s prospectus or in this SAI, a Fund may invest in debt instruments that are not rated by a rating agency. When a debt instrument is not rated by a rating agency, the Investment Manager or, as applicable, a Fund subadviser determines, at the time of purchase, whether such debt instrument is of investment grade or below investment grade (e.g., junk bond) quality. A Fund’s debt instrument holdings that are not rated by a rating agency are typically referred to as “Not Rated” within the Fund’s shareholder reports.

See Appendix A for a discussion of securities ratings.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with debt obligations include: Confidential Information Access Risk, Credit Risk, Highly Leveraged Transactions Risk, Impairment of Collateral Risk, Interest Rate Risk, Issuer Risk, Liquidity Risk, Prepayment and Extension Risk and Reinvestment Risk.

Determining Average Maturity. When determining the average maturity of a Fund's portfolio, the Fund may use the effective maturity of a portfolio security by, among other things, adjusting for interest rate reset dates, call dates or “put” dates.

Depositary Receipts

See Types of Investments – Foreign Securities below.

Derivatives

General

Derivatives are financial instruments whose values are based on (or “derived” from) traditional securities (such as a stock or a bond), assets (such as a commodity, like gold), reference rates (such as LIBOR and SOFR), market indices (such as the S&P 500^® Index) or customized baskets of securities or instruments. Some forms of derivatives, such as exchange-traded futures and options on securities, commodities, or indices, are traded on regulated exchanges. These types of derivatives are standardized contracts that can easily be bought and sold, and whose market values are determined and published daily. Non-standardized derivatives, on the other hand, tend to be more specialized or complex, and may be harder to value. Many derivative instruments often require little or no initial payment and therefore often create inherent economic leverage. Derivatives, when used properly, can enhance returns and be useful in hedging portfolios and managing risk. Some common types of derivatives include futures; options; options on futures; forward foreign currency exchange contracts; forward contracts on securities and securities indices; linked securities and structured products; CMOs; swap agreements and swaptions.

A Fund may use derivatives for a variety of reasons, including, for example: (i) to enhance its return; (ii) to attempt to protect against possible unfavorable changes in the market value of securities held in or to be purchased for its portfolio resulting from securities markets or currency exchange rate fluctuations (i.e., to hedge); (iii) to protect its unrealized gains reflected in the value of its portfolio securities; (iv) to facilitate the sale of such securities for investment purposes; (v) to reduce transaction costs; (vi) to manage the effective maturity or duration of its portfolio; and/or (vii) to maintain cash reserves while remaining fully invested.

Certain Funds may employ portfolio margining with respect to derivatives investments, which creates leverage in a Fund’s portfolio (subjecting the Fund to Leverage Risk). Portfolio margining is a methodology that computes margin requirements for an account based on the greatest projected net loss of all positions in a product class or group, and uses computer modeling to perform risk analysis using multiple pricing scenarios. The pricing scenarios are designed to measure the theoretical loss of the positions, given changes in the underlying price and implied volatility inputs to the model. Accordingly, the margin required is based on the greatest loss that would be incurred in a portfolio if the value of its components move up or down by a predetermined amount.

A Fund may use any or all of the above investment techniques and may purchase different types of derivative instruments at any time and in any combination. The use of derivatives is a function of numerous variables, including market conditions. See also Types of Investments — Warrants and Rights and — Debt Obligations - When Issued, Delayed Delivery and Forward Commitment Transactions.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with transactions in derivatives (including the derivatives instruments discussed below) include: Counterparty Risk, Credit Risk, Interest Rate Risk, Leverage Risk, Liquidity Risk, Market Risk, Derivatives Risk, Derivatives Risk – Forward Contracts Risk, Derivatives Risk – Futures Contracts Risk, Derivatives Risk – Inverse Floaters Risk, Derivatives Risk – Options Risk, Derivatives Risk – Structured Investments Risk and/or Derivatives Risk – Swaps Risk.

Structured Investments (Indexed or Linked Securities)

General. Indexed or linked securities, also often referred to as “structured products,” are instruments that may have varying combinations of equity and debt characteristics. These instruments are structured to recast the investment characteristics of the underlying security or reference asset. If the issuer is a unit investment trust or other special purpose vehicle, the structuring will typically involve the deposit with or purchase by such issuer of specified instruments (such as commercial bank loans or

Statement of Additional Information – [_________, 2022]

Table of Contents

securities) and/or the execution of various derivative transactions, and the issuance by that entity of one or more classes of securities (structured securities) backed by, or representing interests in, the underlying instruments. The cash flow on the underlying instruments may be apportioned among the newly issued structured securities to create securities with different investment characteristics, such as varying maturities, payment priorities and interest rate provisions, and the extent of such payments made with respect to structured securities is dependent on the extent of the cash flow on the underlying instruments.

Indexed and Inverse Floating Rate Securities. A Fund may invest in securities that provide a potential return based on a particular index or interest rates. For example, a Fund may invest in debt securities that pay interest based on an index of interest rates. The principal amount payable upon maturity of certain securities also may be based on the value of the index. To the extent a Fund invests in these types of securities, a Fund’s return on such securities will rise and fall with the value of the particular index: that is, if the value of the index falls, the value of the indexed securities owned by a Fund will fall. Interest and principal payable on certain securities may also be based on relative changes among particular indices.

A Fund may also invest in so-called “inverse floaters” or “residual interest bonds” on which the interest rates vary inversely with a floating rate (which may be reset periodically by a dutch auction, a remarketing agent, or by reference to a short-term tax-exempt interest rate index). A Fund may purchase synthetically-created inverse floating rate bonds evidenced by custodial or trust receipts. A trust funds the purchase of a bond by issuing two classes of certificates: short-term floating rate notes (typically sold to third parties) and the inverse floaters (also known as residual certificates). No additional income beyond that provided by the trust’s underlying bond is created; rather, that income is merely divided-up between the two classes of certificates. Generally, income on inverse floating rate bonds will decrease when interest rates increase, and will increase when interest rates decrease. Such securities can have the effect of providing a degree of investment leverage, since they may increase or decrease in value in response to changes in market interest rates at a rate that is a multiple of the actual rate at which fixed-rate securities increase or decrease in response to such changes. As a result, the market values of such securities will generally be more volatile than the market values of fixed-rate securities. To seek to limit the volatility of these securities, a Fund may purchase inverse floating obligations that have shorter-term maturities or that contain limitations on the extent to which the interest rate may vary. Certain investments in such obligations may be illiquid. Furthermore, where such a security includes a contingent liability, in the event of an adverse movement in the underlying index or interest rate, a Fund may be required to pay substantial additional margin to maintain the position.

Credit-Linked Securities. Among the income-producing securities in which a Fund may invest are credit linked securities. The issuers of these securities frequently are limited purpose trusts or other special purpose vehicles that, in turn, invest in a derivative instrument or basket of derivative instruments, such as credit default swaps, interest rate swaps and other securities, in order to provide exposure to certain fixed income markets. For instance, a Fund may invest in credit-linked securities as a cash management tool in order to gain exposure to a certain market and/or to remain fully invested when more traditional income-producing securities are not available. Like an investment in a bond, investments in these credit linked securities represent the right to receive periodic income payments (in the form of distributions) and payment of principal at the end of the term of the security. However, these payments are conditioned on or linked to the issuer’s receipt of payments from, and the issuer’s potential obligations to, the counterparties to the derivative instruments and other securities in which the issuer invests. For instance, the issuer may sell one or more credit default swaps, under which the issuer would receive a stream of payments over the term of the swap agreements provided that no event of default has occurred with respect to the referenced debt obligation upon which the swap is based. If a default occurs, the stream of payments may stop and the issuer would be obligated to pay the counterparty the par (or other agreed upon value) of the referenced debt obligation. This, in turn, would reduce the amount of income and/or principal that a Fund would receive. A Fund’s investments in these securities are indirectly subject to the risks associated with derivative instruments. These securities generally are exempt from registration under the 1933 Act. Accordingly, there may be no established trading market for the securities and they may be illiquid.

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. 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 portfolio 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.

Statement of Additional Information – [_________, 2022]

Table of Contents

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 not 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.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with equity-linked notes include: Counterparty Risk, Credit Risk, Liquidity Risk and Market Risk.

Index-, Commodity- and Currency-Linked Securities. “Index-linked” or “commodity-linked” notes are debt securities of companies that call for interest payments and/or payment at maturity in different terms than the typical note where the borrower agrees to make fixed interest payments and to pay a fixed sum at maturity. Principal and/or interest payments on an index-linked or commodity-linked note depend on the performance of one or more market indices, such as the S&P 500^® Index, a weighted index of commodity futures such as crude oil, gasoline and natural gas or the market prices of a particular commodity or basket of commodities or securities. Currency-linked debt securities are short-term or intermediate-term instruments having a value at maturity, and/or an interest rate, determined by reference to one or more foreign currencies. Payment of principal or periodic interest may be calculated as a multiple of the movement of one currency against another currency, or against an index.

Index-, commodity- and currency-linked securities may entail substantial risks. Such instruments may be subject to significant price volatility. The company issuing the instrument may fail to pay the amount due on maturity. The underlying investment may not perform as expected by a Fund’s portfolio manager. Markets and underlying investments and indexes may move in a direction that was not anticipated by a Fund’s portfolio manager. Performance of the derivatives may be influenced by interest rate and other market changes in the United States and abroad, and certain derivative instruments may be illiquid.

Linked securities are often issued by unit investment trusts. Examples of this include such index-linked securities as S&P Depositary Receipts (SPDRs), which is an interest in a unit investment trust holding a portfolio of securities linked to the S&P 500^® Index, and a type of exchange-traded fund (ETF). Because a unit investment trust is an investment company under the 1940 Act, a Fund’s investments in SPDRs are subject to the limitations set forth in Section 12(d)(1)(A) of the 1940 Act, although the SEC has issued exemptive relief permitting investment companies such as the Funds to invest beyond the limits of Section 12(d)(1)(A) subject to certain conditions. SPDRs generally closely track the underlying portfolio of securities, trade like a share of common stock and pay periodic dividends proportionate to those paid by the portfolio of stocks that comprise the S&P 500^® Index. As a holder of interests in a unit investment trust, a Fund would indirectly bear its ratable share of that unit investment trust’s expenses. At the same time, a Fund would continue to pay its own management and advisory fees and other expenses, as a result of which a Fund and its shareholders in effect would be absorbing levels of fees with respect to investments in such unit investment trusts.

Because linked securities typically involve no credit enhancement, their credit risk generally will be equivalent to that of the underlying instruments. Investments in structured products may be structured as a class that is either subordinated or unsubordinated to the right of payment of another class. Subordinated linked securities typically have higher rates of return and present greater risks than unsubordinated structured products. Structured products sometimes are sold in private placement transactions and often have a limited trading market.

Investments in linked securities have the potential to lead to significant losses because of unexpected movements in the underlying financial asset, index, currency or other investment. The ability of a Fund to utilize linked securities successfully will depend on its ability correctly to predict pertinent market movements, which cannot be assured. Because currency-linked securities usually relate to foreign currencies, some of which may be currencies from emerging market countries, there are certain additional risks associated with such investments.

Futures Contracts and Options on Futures Contracts

Futures Contracts. A futures contract sale creates an obligation by the seller to deliver the type of security or other asset called for in the contract at a specified delivery time for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type of security or other asset called for in the contract at a specified delivery time for a stated price. The specific security or other asset delivered or taken at the settlement date is not determined until on or near that date. The determination is made in accordance with the rules of the exchange on which the futures contract was made. A Fund may enter into futures contracts which are traded on national or foreign futures exchanges and are standardized as to maturity date and underlying security or other asset. Futures exchanges and trading in the United States are regulated under the CEA by the CFTC, a U.S. Government agency. See CFTC Regulation below for information on CFTC regulation.

Statement of Additional Information – [_________, 2022]

Table of Contents

Traders in futures contracts may be broadly classified as either “hedgers” or “speculators.” Hedgers use the futures markets primarily to offset unfavorable changes (anticipated or potential) in the value of securities or other assets currently owned or expected to be acquired by them. Speculators less often own the securities or other assets underlying the futures contracts which they trade, and generally use futures contracts with the expectation of realizing profits from fluctuations in the value of the underlying securities or other assets.

Upon entering into futures contracts, in compliance with regulatory requirements, cash or liquid securities, at least equal in value to the amount of a Fund’s obligation under the contract (less any applicable margin deposits and any assets that constitute “cover” for such obligation), will be designated in a Fund’s books and records.

Unlike when a Fund purchases or sells a security, no price is paid or received by a Fund upon the purchase or sale of a futures contract, although a Fund is required to deposit with its custodian in a segregated account in the name of the futures broker an amount of cash and/or U.S. Government securities in order to initiate and maintain open positions in futures contracts. This amount is known as “initial margin.” The nature of initial margin in futures transactions is different from that of margin in security transactions, in that futures contract margin does not involve the borrowing of funds by a Fund to finance the transactions. Rather, initial margin is in the nature of a performance bond or good faith deposit intended to assure completion of the contract (delivery or acceptance of the underlying security or other asset) that is returned to a Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Minimum initial margin requirements are established by the relevant futures exchange and may be changed. Brokers may establish deposit requirements which are higher than the exchange minimums. Futures contracts are customarily purchased and sold on margin which may range upward from less than 5% of the value of the contract being traded. Subsequent payments, called “variation margin,” to and from the broker (or the custodian) are made on a daily basis as the price of the underlying security or other asset fluctuates, a process known as “marking to market.” If the futures contract price changes to the extent that the margin on deposit does not satisfy margin requirements, payment of additional variation margin will be required. Conversely, a change in the contract value may reduce the required margin, resulting in a repayment of excess margin to the contract holder. Variation margin payments are made for as long as the contract remains open. A Fund expects to earn interest income on its margin deposits.

Although futures contracts by their terms call for actual delivery or acceptance of securities or other assets (stock index futures contracts or futures contracts that reference other intangible assets do not permit delivery of the referenced assets), the contracts usually are closed out before the settlement date without the making or taking of delivery. A Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of taking such action would be to reduce or eliminate the position then currently held by a Fund. Closing out an open futures position is done by taking an opposite position (“buying” a contract which has previously been “sold,” “selling” a contract previously “purchased”) in an identical contract (i.e., the same aggregate amount of the specific type of security or other asset with the same delivery date) to terminate the position. Final determinations are made as to whether the price of the initial sale of the futures contract exceeds or is below the price of the offsetting purchase, or whether the purchase price exceeds or is below the offsetting sale price. Final determinations of variation margin are then made, additional cash is required to be paid by or released to a Fund, and a Fund realizes a loss or a gain. Brokerage commissions are incurred when a futures contract is bought or sold.

Successful use of futures contracts by a Fund is subject to its portfolio manager’s ability to predict correctly movements in the direction of interest rates and other factors affecting securities and commodities markets. This requires different skills and techniques than those required to predict changes in the prices of individual securities. A Fund, therefore, bears the risk that future market trends will be incorrectly predicted.

The risk of loss in trading futures contracts in some strategies can be substantial, due both to the relatively low margin deposits required and the potential for an extremely high degree of leverage involved in futures contracts. As a result, a relatively small price movement in a futures contract may result in an immediate and substantial loss to the investor. For example, if at the time of purchase, 10% of the value of the futures contract is deposited as margin, a subsequent 10% decrease in the value of the futures contract would result in a total loss of the margin deposit, before any deduction for the transaction costs, if the account were then closed out. A 15% decrease would result in a loss equal to 150% of the original margin deposit if the contract were closed out. Thus, a purchase or sale of a futures contract may result in losses in excess of the amount posted as initial margin for the contract.

In the event of adverse price movements, a Fund would continue to be required to make daily cash payments in order to maintain its required margin. In such a situation, if a Fund has insufficient cash, it may have to sell portfolio securities in order to meet daily margin requirements at a time when it may be disadvantageous to do so. The inability to close the futures position also could have an adverse impact on the ability to hedge effectively.

To reduce or eliminate a hedge position held by a Fund, a Fund may seek to close out a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract, which may limit a Fund’s ability to realize its profits or limit its losses. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be

insufficient trading interest in certain contracts; (ii) restrictions may be imposed by an exchange on opening transactions, closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts, or underlying securities; (iv) unusual or unforeseen circumstances, such as volume in excess of trading or clearing capability, may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts (or a particular class or series of contracts), in which event the secondary market on that exchange (or in the class or series of contracts) would cease to exist, although outstanding contracts on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

Interest Rate Futures Contracts. Bond prices are established in both the cash market and the futures market. In the cash market, bonds are purchased and sold with payment for the full purchase price of the bond being made in cash, generally within five business days after the trade. In the futures market, a contract is made to purchase or sell a bond in the future for a set price on a certain date. Historically, the prices for bonds established in the futures markets have tended to move generally in the aggregate in concert with the cash market prices and have maintained fairly predictable relationships. Accordingly, a Fund may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. A Fund presently could accomplish a similar result to that which it hopes to achieve through the use of interest rate futures contracts by selling bonds with long maturities and investing in bonds with short maturities when interest rates are expected to increase, or conversely, selling bonds with short maturities and investing in bonds with long maturities when interest rates are expected to decline. However, because of the liquidity that is often available in the futures market, the protection is more likely to be achieved, perhaps at a lower cost and without changing the rate of interest being earned by a Fund, through using futures contracts.

Interest rate futures contracts are exchange-traded in an auction environment. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership. A public market exists in futures contracts covering various financial instruments including long-term U.S. Treasury Bonds and Notes; GNMA modified pass-through mortgage backed securities; three-month U.S. Treasury Bills; and ninety-day commercial paper. A Fund may also invest in exchange-traded Eurodollar contracts, which are interest rate futures on the forward level of a reference rate. These contracts are generally considered liquid securities and trade on the Chicago Mercantile Exchange. Such Eurodollar contracts are generally used to “lock-in” or hedge the future level of short-term rates. A Fund may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

Index Futures Contracts. An index futures contract is a contract to buy or sell units of an index at a specified future date at a price agreed upon when the contract is made. Entering into a contract to buy units of an index is commonly referred to as buying or purchasing a contract or holding a long position in the index. Entering into a contract to sell units of an index is commonly referred to as selling a contract or holding a short position in the index. A unit is the current value of the index. A Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s).

Municipal Bond Index Futures Contracts. Municipal bond index futures contracts may act as a hedge against changes in market conditions. A municipal bond index assigns values daily to the municipal bonds included in the index based on the independent assessment of dealer-to-dealer municipal bond brokers. A municipal bond index futures contract represents a firm commitment by which two parties agree to take or make delivery of an amount equal to a specified dollar amount multiplied by the difference between the municipal bond index value on the last trading date of the contract and the price at which the futures contract is originally struck. No physical delivery of the underlying securities in the index is made.

Commodity-Linked Futures Contracts. Commodity-linked futures contracts are traded on futures exchanges. These futures exchanges offer a central marketplace in which to transact in futures contracts, a clearing corporation to process trades, and standardization of expiration dates and contract sizes. Futures markets also specify the terms and conditions of delivery as well as the maximum permissible price movement during a trading session. Additionally, the commodity futures exchanges may have position limit rules that limit the amount of futures contracts that any one party may hold in a particular commodity at any point in time. These position limit rules are designed to prevent any one participant from controlling a significant portion of the market.

Commodity-linked futures contracts are generally based upon commodities within six main commodity groups: (1) energy, which includes, among others, crude oil, brent crude oil, gas oil, natural gas, gasoline and heating oil; (2) livestock, which includes, among others, feeder cattle, live cattle and hogs; (3) agriculture, which includes, among others, wheat (Kansas wheat and Chicago wheat), corn and soybeans; (4) industrial metals, which includes, among others, aluminum, copper, lead, nickel and zinc; (5) precious metals, which includes, among others, gold and silver; and (6) softs, which includes cotton, coffee, sugar and cocoa. A Fund may purchase commodity futures contracts, swaps on commodity futures contracts, options on futures contracts and options and futures on commodity indices with respect to these six main commodity groups and the individual commodities within each group, as well as other types of commodities.

Statement of Additional Information – [_________, 2022]

The price of a commodity futures contract will reflect the storage costs of purchasing the physical commodity. These storage costs include the time value of money invested in the physical commodity plus the actual costs of storing the commodity less any benefits from ownership of the physical commodity that are not obtained by the holder of a futures contract (this is sometimes referred to as the “convenience yield”). To the extent that these storage costs change for an underlying commodity while a Fund is long futures contracts on that commodity, the value of the futures contract may change proportionately.

In the commodity futures markets, if producers of the underlying commodity wish to hedge the price risk of selling the commodity, they will sell futures contracts today to lock in the price of the commodity at delivery tomorrow. In order to induce speculators to take the corresponding long side of the same futures contract, the commodity producer must be willing to sell the futures contract at a price that is below the expected future spot price. Conversely, if the predominant hedgers in the futures market are the purchasers of the underlying commodity who purchase futures contracts to hedge against a rise in prices, then speculators will only take the short side of the futures contract if the futures price is greater than the expected future spot price of the commodity.

The changing nature of the hedgers and speculators in the commodity markets will influence whether futures contract prices are above or below the expected future spot price. This can have significant implications for a Fund when it is time to replace an existing contract with a new contract. If the nature of hedgers and speculators in futures markets has shifted such that commodity purchasers are the predominant hedgers in the market, a Fund might open the new futures position at a higher price or choose other related commodity-linked investments.

The values of commodities which underlie commodity futures contracts are subject to additional variables which may be less significant to the values of traditional securities such as stocks and bonds. Variables such as drought, floods, weather, livestock disease, embargoes and tariffs may have a larger impact on commodity prices and commodity-linked investments, including futures contracts, commodity-linked structured notes, commodity-linked options and commodity-linked swaps, than on traditional securities. These additional variables may create additional investment risks which subject a Fund’s commodity-linked investments to greater volatility than investments in traditional securities.

Options on Futures Contracts. A Fund may purchase and write call and put options on those futures contracts that it is permitted to buy or sell. A Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or other assets or purchasing and selling the underlying futures contracts. Such options generally operate in the same manner as options purchased or written directly on the underlying investments. A futures option gives the holder, in return for the premium paid, the right, but not the obligation, to buy from (call) or sell to (put) the writer of the option a futures contract at a specified price at any time during the period of the option. Upon exercise, the writer of the option is obligated to pay the difference between the cash value of the futures contract and the exercise price. Like the buyer or seller of a futures contract, the holder or writer of an option has the right to terminate its position prior to the scheduled expiration of the option by selling or purchasing an option of the same series, at which time the person entering into the closing purchase transaction will realize a gain or loss. There is no guarantee that such closing purchase transactions can be effected.

A Fund will enter into written options on futures contracts only when, in compliance with regulatory requirements, it has designated cash or liquid securities at least equal in value to the underlying security’s or other asset’s value (less any applicable margin deposits). A Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers’ requirements similar to those described above.

Options on Index Futures Contracts. A Fund may also purchase and sell options on index futures contracts. Options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if the option is a call and a short position if the option is a put), at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer’s futures margin account, which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

Use by Tax-Exempt Funds of Interest Rate and U.S. Treasury Security Futures Contracts and Options. If a Fund invests in tax-exempt securities, it may purchase and sell futures contracts and related options on interest rate and U.S. Treasury securities when, in the opinion of a Fund’s portfolio manager, price movements in these security futures and related options will correlate closely with price movements in the tax-exempt securities which are the subject of the hedge. Interest rate and U.S. Treasury securities futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of security called for in the contract at a specified date and price. Options on interest rate and U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a futures contract at the specified option exercise price at any time during the period of the option.

Eurodollar and Yankee Dollar Futures Contracts and Options Thereon. Eurodollar futures contracts enable purchasers to obtain a fixed rate for the lending of funds and sellers to obtain a fixed rate for borrowings. A Fund may use Eurodollar futures contracts and options thereon to hedge against changes in a reference rate, such as LIBOR or SOFR, to which many interest rate swaps and fixed income instruments are linked.

Options

Options on Stocks, Stock Indices and Other Indices. A Fund may purchase and write (i.e., sell) put and call options. Such options may relate to particular stocks or stock indices, and may or may not be listed on a domestic or foreign securities exchange and may or may not be issued by the Options Clearing Corporation (OCC). Stock index options are put options and call options on various stock indices. In most respects, they are identical to listed options on common stocks.

There is a key difference between stock options and index options in connection with their exercise. In the case of stock options, the underlying security, common stock, is delivered. However, upon the exercise of an index option, settlement does not occur by delivery of the securities comprising the index. The option holder who exercises the index option receives an amount of cash if the closing level of the stock index upon which the option is based is greater than (in the case of a call) or less than (in the case of a put) the exercise price of the option. This amount of cash is equal to the difference between the closing price of the stock index and the exercise price of the option expressed in dollars times a specified multiple. A stock index fluctuates with changes in the market value of the securities included in the index. For example, some stock index options are based on a broad market index, such as the S&P 500^® Index or a narrower market index, such as the S&P 100^® Index. Indices may also be based on an industry or market segment.

A Fund may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges.

As an alternative to purchasing call and put options on index futures, a Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the OCC. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

Writing Covered Options. A Fund may write covered call options and covered put options on securities held in its portfolio. Call options written by a Fund give the purchaser the right to buy the underlying securities from a Fund at the stated exercise price at any time prior to the expiration date of the option, regardless of the security’s market price; put options give the purchaser the right to sell the underlying securities to a Fund at the stated exercise price at any time prior to the expiration date of the option, regardless of the security’s market price.

A Fund may write covered options, which means that, so long as a Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option (or comparable securities satisfying the cover requirements of securities exchanges). In the case of put options, a Fund will hold liquid assets equal to the price to be paid if the option is exercised. In addition, a Fund will be considered to have covered a put or call option if and to the extent that it holds an option that offsets some or all of the risk of the option it has written. A Fund may write combinations of covered puts and calls (straddles) on the same underlying security.

A Fund will receive a premium from writing a put or call option, which increases a Fund’s return on the underlying security if the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security. By writing a call option, a Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option but continues to bear the risk of a decline in the value of the underlying security. By writing a put option, a Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than the security’s then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

A Fund’s obligation to sell an instrument subject to a call option written by it, or to purchase an instrument subject to a put option written by it, may be terminated prior to the expiration date of the option by a Fund’s execution of a closing purchase transaction, which is effected by purchasing on an exchange an offsetting option of the same series (i.e., same underlying instrument, exercise price and expiration date) as the option previously written. A closing purchase transaction will ordinarily be effected in order to realize a profit on an outstanding option, to prevent an underlying instrument from being called, to permit the sale of the underlying instrument or to permit the writing of a new option containing different terms on such underlying instrument. A Fund realizes a profit or loss from a closing purchase transaction if the cost of the transaction (option premium

Table of Contents

plus transaction costs) is less or more than the premium received from writing the option. Because increases in the market price of a call option generally reflect increases in the market price of the security underlying the option, any loss resulting from a closing purchase transaction may be offset in whole or in part by unrealized appreciation of the underlying security.

If a Fund writes a call option but does not own the underlying security, and when it writes a put option, a Fund may be required to deposit cash or securities with its broker as “margin” or collateral for its obligation to buy or sell the underlying security. As the value of the underlying security varies, a Fund may also have to deposit additional margin with the broker. Margin requirements are complex and are fixed by individual brokers, subject to minimum requirements currently imposed by the Federal Reserve Board and by stock exchanges and other self-regulatory organizations.

Purchasing Put Options. A Fund may purchase put options to protect its portfolio holdings in an underlying security against a decline in market value. Such hedge protection is provided during the life of the put option since a Fund, as holder of the put option, is able to sell the underlying security at the put exercise price regardless of any decline in the underlying security’s market price. For a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs. By using put options in this manner, a Fund will reduce any profit it might otherwise have realized from appreciation of the underlying security by the premium paid for the put option and by transaction costs.

Purchasing Call Options. A Fund may purchase call options, including call options to hedge against an increase in the price of securities that a Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since a Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security’s market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit a Fund might have realized had it bought the underlying security at the time it purchased the call option.

Over-the-Counter (OTC) Options. OTC options (options not traded on exchanges) are generally established through negotiation with the other party to the options contract. A Fund will enter into OTC options transactions only with primary dealers in U.S. Government securities and, in the case of OTC options written by a Fund, only pursuant to agreements that will assure that a Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price.

Swap Agreements

General. Swap agreements are derivative instruments that can be individually negotiated and structured to include exposure to a variety of different types of investments or market factors. Depending on their structure, swap agreements may increase or decrease a Fund’s exposure to long- or short-term interest rates, foreign currency values, mortgage securities, corporate borrowing rates, or other factors such as security prices or inflation rates. A Fund may enter into a variety of swap agreements, including interest rate, index, commodity, commodity futures, equity, equity index, credit default, bond futures, total return, currency exchange rate, and other types of swap agreements such as caps, collars and floors. A Fund also may enter into swaptions, which are options to enter into a swap agreement.

Swap agreements are usually entered into without an upfront payment because the value of each party’s position is the same. The market values of the underlying commitments will change over time, resulting in one of the commitments being worth more than the other and the net market value creating a risk exposure for one party or the other.

In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a “notional principal amount,” in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amounts as well. In a total return swap agreement, the non-floating rate side of the swap is based on the total return of an individual security, a basket of securities, an index or another reference asset. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed-upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed-upon level. Caps and floors have an effect similar to buying or writing options. A collar combines elements of buying a cap and selling a floor. In interest rate collar transactions, one party sells a cap and purchases a floor, or vice versa, in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels or collar amounts.

Swap agreements will tend to shift a Fund’s investment exposure from one type of investment to another. For example, if a Fund agreed to pay fixed rates in exchange for floating rates while holding fixed-rate bonds, the swap would tend to decrease a Fund’s exposure to long-term interest rates. Another example is if a Fund agreed to exchange payments in dollars for payments in foreign currency. In that case, the swap agreement would tend to decrease a Fund’s exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates.

Because swaps are two-party contracts that may be subject to contractual restrictions on transferability and termination and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid. If a swap is not liquid, 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.

Moreover, a 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 agreement counterparty. When a counterparty’s obligations are not fully secured by collateral, then the Fund is essentially an unsecured creditor of the counterparty. If the counterparty defaults, the Fund will have contractual remedies, but there is no assurance that a counterparty will be able to meet its obligations pursuant to such contracts or that, in the event of default, the Fund will succeed in enforcing contractual remedies. Counterparty risk still exists even if a counterparty’s obligations are secured by collateral because the Fund’s interest in collateral may not be perfected or additional collateral may not be promptly posted as required. Counterparty risk also may be more pronounced if a counterparty’s obligations exceed the amount of collateral held by the Fund (if any), the Fund is unable to exercise its interest in collateral upon default by the counterparty, or the termination value of the instrument varies significantly from the marked-to-market value of the instrument.

Counterparty risk with respect to derivatives will be affected by new rules and regulations affecting the derivatives market. Some derivatives transactions are required to be centrally cleared, and a party to a cleared derivatives transaction is subject to the credit risk of the clearing house and the clearing member through which it holds its cleared position, rather than the credit risk of its original counterparty to the derivative transaction. Credit risk of market participants with respect to derivatives that are centrally cleared is concentrated in a few clearing houses, and it is not clear how an insolvency proceeding of a clearing house would be conducted and what impact an insolvency of a clearing house would have on the financial system. A clearing member is obligated by contract and by applicable regulation to segregate all funds received from customers with respect to cleared derivatives transactions from the clearing member’s proprietary assets. However, all funds and other property received by a clearing broker from its customers are generally held by the clearing broker on a commingled basis in an omnibus account, and the clearing member may invest those funds in certain instruments permitted under the applicable regulations. The assets of a Fund might not be fully protected in the event of the bankruptcy of a Fund’s clearing member, because the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing broker’s customers for a relevant account class. Also, the clearing member is required to transfer to the clearing organization the amount of margin required by the clearing organization for cleared derivatives, which amounts are generally held in an omnibus account at the clearing organization for all customers of the clearing member. Regulations promulgated by the CFTC require that the clearing member notify the clearing house of the amount of initial margin provided by the clearing member to the clearing organization that is attributable to each customer. However, if the clearing member does not provide accurate reporting, the Funds are subject to the risk that a clearing organization will use a Fund’s assets held in an omnibus account at the clearing organization to satisfy payment obligations of a defaulting customer of the clearing member to the clearing organization. In addition, clearing members generally provide to the clearing organization the net amount of variation margin required for cleared swaps for all of its customers in the aggregate, rather than the gross amount of each customer. The Funds are therefore subject to the risk that a clearing organization will not make variation margin payments owed to a Fund if another customer of the clearing member has suffered a loss and is in default, and the risk that a Fund will be required to provide additional variation margin to the clearing house before the clearing house will move the Fund’s cleared derivatives transactions to another clearing member. In addition, if a clearing member does not comply with the applicable regulations or its agreement with the Funds, or in the event of fraud or misappropriation of customer assets by a clearing member, a Fund could have only an unsecured creditor claim in an insolvency of the clearing member with respect to the margin held by the clearing member.

Interest Rate Swaps. Interest rate swap agreements are often used to obtain or preserve a desired return or spread at a lower cost than through a direct investment in an instrument that yields the desired return or spread. They are financial instruments that involve the exchange of one type of interest rate cash flow for another type of interest rate cash flow on specified dates in the future. In a standard interest rate swap transaction, two parties agree to exchange their respective commitments to pay fixed or floating interest rates on a predetermined specified (notional) amount. The swap agreement’s notional amount is the predetermined basis for calculating the obligations that the swap counterparties have agreed to exchange. Under most swap agreements, the obligations of the parties are exchanged on a net basis. The two payment streams are netted out, with each party receiving or paying, as the case may be, only the net amount of the two payments. Interest rate swaps can be based on various measures of interest rates, including swap rates, Treasury rates, foreign interest rates and other reference rates.

Municipal Market Data (MMD) Rate Locks. An MMD Rate Lock permits a Fund to lock in a specific municipal interest rate for a portion of its portfolio to preserve a return on a particular investment or a portion of its portfolio, which in turn protects against any increase in the price of securities to be purchased at a later date. By using an MMD Rate Lock, the Fund can create a synthetic long or short duration position. A Fund will ordinarily use these transactions as a hedge or for duration or risk management, which may not be successful. An MMD Rate Lock is a contract between a Fund and an MMD Rate Lock provider pursuant to which the parties agree to make a net settlement payment to each other on a notional and duration amount,

Statement of Additional Information – [_________, 2022]

Table of Contents

contingent upon whether the Municipal Market Data AAA General Obligation Scale is above or below a specified level on the expiration date of the contract. For example, if a Fund buys an MMD Rate Lock and the Municipal Market Data AAA General Obligation Scale is below the specified level on the expiration date, the counterparty to the contract will make a payment to a Fund equal to the specified level minus the actual level, multiplied by the notional amount of the contract. If the Municipal Market Data AAA General Obligation Scale is above the specified level on the expiration date, a Fund will make a payment to the counterparty equal to the actual level minus the specified level, multiplied by the notional amount of the contract. In connection with investments in MMD Rate Locks, there is a risk that municipal yields will move in the opposite direction than anticipated by a Fund, which would cause the Fund to make payments to its counterparty in the transaction that could adversely affect the Fund’s performance.

Credit Default Swap Agreements. A Fund may enter into credit default swap agreements, which may have as reference obligations one or more securities or a basket of securities that are or are not currently held by a Fund. The protection “buyer” in a credit default contract is generally obligated to pay the protection “seller” an upfront or a periodic stream of payments over the term of the contract provided that no credit event, such as a default, on a reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the “par value” (full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be required to deliver the related net cash amount, if the swap is cash settled. A Fund may be either the buyer or seller in a credit default swap. If a Fund is a buyer and no credit event occurs, a Fund may recover nothing if the swap is held through its termination date. However, if a credit event occurs, the buyer generally may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value may have significantly decreased. As a seller, a Fund generally receives an upfront payment or a fixed rate of income throughout the term of the swap provided that there is no credit event. As the seller, a Fund would effectively add leverage to its portfolio because, in addition to its total net assets, a Fund would be subject to investment exposure on the notional amount of the swap.

Credit default swap agreements may involve greater risks than if a Fund had invested in the reference obligation directly since, in addition to risks relating to the reference obligation, credit default swaps are subject to liquidity risk, counterparty risk and credit risk. A Fund will enter into credit default swap agreements generally with counterparties that meet certain standards of creditworthiness. A buyer generally will lose its investment and recover nothing if no credit event occurs and the swap is held to its termination date. If a credit event were to occur, the value of any deliverable obligation received by the seller, coupled with the upfront or periodic payments previously received, may be less than the full notional value it pays to the buyer, resulting in a loss of value to the seller.

A Fund’s obligations under a credit default swap agreement will be accrued daily (offset against any amounts owing to the Fund). For bilateral credit default swaps (CDS) where the Fund is the seller of protection, the Fund will cover the full notional amount of the swap minus any collateral on deposit. In connection with credit default swaps in which a Fund is the buyer, the Fund will segregate or designate cash or other liquid assets in accordance with its policies and procedures. Such segregation or designation will ensure that a Fund has assets available to satisfy its obligations with respect to the transaction. Such segregation or designation will not limit a Fund’s exposure to loss.

Equity Swaps. A Fund may engage in equity swaps. Equity swaps allow the parties to the swap agreement to exchange components of return on one equity investment (e.g., a basket of equity securities or an index) for a component of return on another non-equity or equity investment, including an exchange of differential rates of return. Equity swaps may be used to invest in a market without owning or taking physical custody of securities in circumstances where direct investment may be restricted for legal reasons or is otherwise impractical. Equity swaps also may be used for other purposes, such as hedging or seeking to increase total return.

Total Return Swap Agreements. Total return swap agreements are contracts in which one party agrees to make periodic payments to another party based on the change in market value of the assets underlying the contract, which may include a specified security, basket of securities or securities indices during the specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. Total return swap agreements may be used to obtain exposure to a security or market without owning or taking physical custody of such security or investing directly in such market. Total return swap agreements may effectively add leverage to a Fund’s portfolio because, in addition to its total net assets, a Fund would be subject to investment exposure on the notional amount of the swap.

Total return swap agreements are subject to the risk that a counterparty will default on its payment obligations to a Fund thereunder, and conversely, that a Fund will not be able to meet its obligation to the counterparty. Generally, a Fund will enter into total return swaps on a net basis (i.e., the two payment streams are netted against one another with a Fund receiving or paying, as the case may be, only the net amount of the two payments). The net amount of the excess, if any, of a Fund’s obligations over its entitlements with respect to each total return swap will be accrued on a daily basis, and an amount of liquid assets having an aggregate net asset value at least equal to the accrued excess will be designated by a Fund in its books and records. If the total return swap transaction is entered into on other than a net basis, the full amount of a Fund’s obligations will

be accrued on a daily basis, and the full amount of a Fund’s obligations will be designated by a Fund in an amount equal to or greater than the market value of the liabilities under the total return swap agreement or the amount it would have cost a Fund initially to make an equivalent direct investment, plus or minus any amount a Fund is obligated to pay or is to receive under the total return swap agreement.

Variance, Volatility and Correlation Swap Agreements. Variance and volatility swaps are contracts that provide exposure to increases or decreases in the volatility of certain referenced assets. Correlation swaps are contracts that provide exposure to increases or decreases in the correlation between the prices of different assets or different market rates.

Commodity-Linked Swaps. Commodity-linked swaps are two-party contracts in which the parties agree to exchange the return or interest rate on one instrument for the return of a particular commodity, commodity index or commodities futures or options contract. The payment streams are calculated by reference to an agreed upon notional amount. A one-period swap contract operates in a manner similar to a forward or futures contract because there is an agreement to swap a commodity for cash at only one forward date. A Fund may engage in swap transactions that have more than one period and therefore more than one exchange of commodities.

A Fund may invest in total return commodity swaps to gain exposure to the overall commodity markets. In a total return commodity swap, a Fund will receive the price appreciation of a commodity index, a portion of the index, or a single commodity in exchange for paying an agreed-upon fee. If the commodity swap is for one period, the Fund will pay a fixed fee, established at the outset of the swap. However, if the term of the commodity swap is more than one period, with interim swap payments, the Fund will pay an adjustable or floating fee. With a “floating” rate, the fee is pegged to a reference rate such as LIBOR or SOFR, and is adjusted each period. Therefore, if interest rates increase over the term of the swap contract, a Fund may be required to pay a higher fee at each swap reset date.

Cross Currency Swaps. Cross currency swaps are similar to interest rate swaps, except that they involve multiple currencies. A Fund may enter into a cross currency swap when it has exposure to one currency and desires exposure to a different currency. Typically, the interest rates that determine the currency swap payments are fixed, although occasionally one or both parties may pay a floating rate of interest. Unlike an interest rate swap, however, the principal amounts are exchanged at the beginning of the contract and returned at the end of the contract. In addition to paying and receiving amounts at the beginning and termination of the agreements, both sides will have to pay in full periodically based upon the currency they have borrowed. Changes in foreign exchange currency rates and changes in interest rates, as described above, may negatively affect currency swaps.

Contracts for Differences. Contracts for differences are swap arrangements in which the parties agree that their return (or loss) will be based on the relative performance of two different groups or baskets of securities. Often, one or both baskets will be an established securities index. A Fund’s return will be based on changes in value of theoretical long futures positions in the securities comprising one basket (with an aggregate face value equal to the notional amount of the contract for differences) and theoretical short futures positions in the securities comprising the other basket. A Fund also may use actual long and short futures positions and achieve similar market exposure by netting the payment obligations of the two contracts. A Fund typically enters into contracts for differences (and analogous futures positions) when its portfolio manager believes that the basket of securities constituting the long position will outperform the basket constituting the short position. If the short basket outperforms the long basket, a Fund will realize a loss — even in circumstances when the securities in both the long and short baskets appreciate in value.

Swaptions. A swaption is an options contract on a swap agreement. These transactions give a party the right (but not the obligation) to enter into new swap agreements or to shorten, extend, cancel or otherwise modify an existing swap agreement (which are described herein) at some designated future time on specified terms, in return for payment of the purchase price (the “premium”) of the option. A Fund may write (sell) and purchase put and call swaptions to the same extent it may make use of standard options on securities or other instruments. The writer of the contract receives the premium and bears the risk of unfavorable changes in the market value on the underlying swap agreement. Swaptions can be bundled and sold as a package. These are commonly called interest rate caps, floors and collars (which are described herein).

Many swaps are complex and often valued subjectively. Many over-the-counter derivatives are complex and their valuation often requires modeling and judgment, which increases the risk of mispricing or incorrect valuation. The pricing models used may not produce valuations that are consistent with the values the Fund realizes when it closes or sells an over-the-counter derivative. Valuation risk is more pronounced when the Fund enters into over-the-counter derivatives with specialized terms because the market value of those derivatives in some cases is determined in part by reference to similar derivatives with more standardized terms. Incorrect valuations may result in increased cash payment requirements to counterparties, undercollateralization and/or errors in calculation of the Fund’s net asset value.

Title VII of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) established a framework for the regulation of OTC swap markets; the framework outlined the joint responsibility of the CFTC and the SEC in regulating swaps. The CFTC is responsible for the regulation of swaps, the SEC is responsible for the regulation of security-based swaps and they are both jointly responsible for the regulation of mixed swaps.

Risk of Potential Governmental Regulation of Derivatives

It is possible that government regulation of various types of derivative instruments, including futures and swap agreements, may limit or prevent the Funds from using such instruments as a part of their investment strategy, and could ultimately prevent the Funds from being able to achieve their investment objectives. The effects of present or future legislation and regulation in this area are not known, but the effects could be substantial and adverse.

The futures markets are subject to comprehensive statutes, regulations, and margin requirements. In addition, the SEC, CFTC and the exchanges are authorized to take extraordinary actions in the event of a market emergency, including, for example, the implementation or reduction of speculative position limits, the implementation of higher margin requirements, the establishment of daily price limits and the suspension of trading.

The regulation of swaps and futures transactions in the U.S. is a rapidly changing area of law and is subject to modification by government and judicial action. There is a possibility of future regulatory changes altering, perhaps to a material extent, the nature of an investment in a Fund or the ability of a Fund to continue to implement its investment strategies. In particular, the Dodd-Frank Act, which was signed into law in July 2010, has changed the way in which the U.S. financial system is supervised and regulated. Title VII of the Dodd-Frank Act sets forth a new legislative framework for OTC derivatives, such as swaps, in which the Funds may invest. Title VII of the Dodd-Frank Act makes broad changes to the OTC derivatives market, grants significant new authority to the SEC and the CFTC to regulate OTC derivatives and market participants, and will require clearing of many OTC derivatives transactions.

Recent U.S. and non-U.S. legislative and regulatory reforms, including those related to the Dodd-Frank Act, have resulted in, and may in the future result in, new regulation of derivative instruments and the Fund's use of such instruments. New regulations could, among other things, restrict the Fund's ability to engage in derivative transactions (for example, by making certain types of derivative instruments or transactions no longer available to the Fund) and/or increase the costs of such transactions, and the Fund may as a result be unable to execute its investment strategies in a manner the Investment Manager might otherwise choose.

Additional Risk Factors in Cleared Derivatives Transactions

Under recently adopted rules and regulations, transactions in some types of swaps (including interest rate swaps and credit default swaps on North American and European indices) are required to be centrally cleared. In a transaction involving those swaps (“cleared derivatives”), a Fund’s counterparty is a clearing house, rather than a bank or broker. Since the Funds are not members of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Funds will hold cleared derivatives through accounts at clearing members. In a cleared derivatives transaction, the Funds will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Clearing members guarantee performance of their clients’ obligations to the clearing house.

In many ways, centrally cleared derivative arrangements are less favorable to open-end funds than bilateral arrangements. For example, the Funds may be required to provide greater amounts of margin for cleared derivatives positions than for bilateral derivatives transactions. Also, in contrast to a bilateral derivatives position, following a period of notice to a Fund, a clearing member generally can require termination of an existing cleared derivatives position at any time or increases in margin requirements above the margin that the clearing member required at the beginning of a transaction. Clearing houses also have broad rights to increase margin requirements for existing positions or to terminate those positions at any time. Any increase in margin requirements or termination of existing cleared derivatives positions by the clearing member or the clearing house could interfere with the ability of a Fund to pursue its investment strategy. Further, any increase in margin requirements by a clearing member could also expose a Fund to greater credit risk to its clearing member, because margin for cleared derivatives transactions in excess of clearing house’s margin requirements typically is held by the clearing member. Also, a Fund is subject to risk if it enters into a derivatives transaction that is required to be cleared (or that the Investment Manager expects to be cleared), and no clearing member is willing or able to clear the transaction on the Fund’s behalf. While the documentation in place between the Funds and their clearing members generally provides that the clearing members will accept for clearing all transactions submitted for clearing that are within credit limits (specified in advance) for each Fund, the Funds are still subject to the risk that no clearing member will be willing or able to clear a transaction. In those cases, the position might have to be terminated, and the Fund could lose some or all of the benefit of the position, including loss of an increase in the value of the position and/or loss of hedging protection. In addition, the documentation governing the relationship between the Funds and clearing members is developed by the clearing members and generally is less favorable to the Funds than typical bilateral derivatives documentation. For example, documentation relating to cleared derivatives generally includes a one-way indemnity

Statement of Additional Information – [_________, 2022]

Table of Contents

by the Funds in favor of the clearing member for losses the clearing member incurs as the Funds’ clearing member and typically does not provide the Funds any remedies if the clearing member defaults or becomes insolvent. While futures contracts entail similar risks, the risks likely are more pronounced for cleared swaps due to their more limited liquidity and market history.

Some types of cleared derivatives are required to be executed on an exchange or on a swap execution facility. A swap execution facility is a trading platform where multiple market participants can execute derivatives by accepting bids and offers made by multiple other participants in the platform. While this execution requirement is designed to increase transparency and liquidity in the cleared derivatives market, trading on a swap execution facility can create additional costs and risks for the Funds. For example, swap execution facilities typically charge fees, and if a Fund executes derivatives on a swap execution facility through a broker intermediary, the intermediary may impose fees as well. Also, a Fund may indemnify a swap execution facility, or a broker intermediary who executes cleared derivatives on a swap execution facility on the Fund’s behalf, against any losses or costs that may be incurred as a result of the Fund’s transactions on the swap execution facility.

These and other new rules and regulations could, among other things, further restrict a Fund’s ability to engage in, or increase the cost to the Fund of, derivatives transactions, for example, by making some types of derivatives no longer available to the Fund, increasing margin or capital requirements, or otherwise limiting liquidity or increasing transaction costs. These regulations are new and evolving, so their potential impact on the Funds and the financial system are not yet known. While the new regulations and the central clearing of some derivatives transactions are designed to reduce systemic risk (i.e., the risk that the interdependence of large derivatives dealers could cause a number of those dealers to suffer liquidity, solvency or other challenges simultaneously), there is no assurance that the new clearing mechanisms will achieve that result, and in the meantime, as noted above, central clearing and related requirements expose the Funds to new kinds of risks and costs.

CFTC Regulation

Each of the Funds listed on the cover of this SAI qualifies for an exclusion from the definition of a commodity pool under the CEA and has on file a notice of exclusion under CFTC Rule 4.5. Accordingly, the Investment Manager is not subject to registration or regulation as a “commodity pool operator” under the CEA with respect to these Funds, although the Investment Manager is a registered “commodity pool operator” and “commodity trading advisor”. To remain eligible for the exclusion, each of these Funds is limited in its ability to use certain financial instruments regulated under the CEA (“commodity interests”), including futures and options on futures and certain swaps transactions. In the event that a Fund’s investments in commodity interests are not within the thresholds set forth in the exclusion, one or more Funds not currently registered as a “commodity pool” may be required to register as such, which could increase Fund expenses, adversely affecting the Fund’s total return.

Dollar Rolls

Dollar rolls involve selling securities (e.g., mortgage-backed securities or U.S. Treasury securities) and simultaneously entering into a commitment to purchase those or similar securities on a specified future date and price from the same party. Mortgage dollar rolls and U.S. Treasury rolls are types of dollar rolls. A Fund foregoes principal and interest paid on the securities during the “roll” period. A Fund is compensated by the difference between the current sales price and the lower forward price for the future purchase of the securities, as well as the interest earned on the cash proceeds of the initial sale. The investor also could be compensated through the receipt of fee income equivalent to a lower forward price. Dollar roll transactions may result in higher transaction costs for a Fund.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with mortgage dollar rolls include: Counterparty Risk, Credit Risk and Interest Rate Risk.

Exchange-traded notes (ETNs)

ETNs are instruments that combine aspects of bonds and exchange-traded funds (ETFs) and are designed to provide investors with access to the returns, less investor fees and expenses, of various market benchmarks or strategies to which they are usually linked. When an investor buys an ETN, the issuer, typically an underwriting bank, promises to pay upon maturity the amount reflected in the benchmark or strategy (minus fees and expenses). Some ETNs make periodic coupon payments. Like ETFs, ETNs are traded on an exchange, but ETNs have additional risks compared to ETFs, including the risk that if the credit of the ETN issuer becomes suspect, the investment might lose some or all of its value. Though linked to the performance, for example, of a market benchmark, ETNs are not equities or index funds, but they do share several characteristics. Similar to equities, ETNs are traded on an exchange and can be sold short. Similar to index funds, ETNs may be linked to the return of a benchmark or strategy, but ETNs do not have an ownership interest in the instruments underlying the benchmark or strategy the ETN is tracking.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with exchange-traded notes include: Counterparty Risk, Credit Risk and Market Risk.

Foreign Currency Transactions

The following is applicable to the extent that a fund invests in foreign securities. Because investments in foreign securities usually involve currencies of foreign countries and because a Fund may hold cash and cash equivalent investments in foreign currencies, the value of a Fund’s assets as measured in U.S. dollars may be affected favorably or unfavorably by changes in currency exchange rates and exchange control regulations. Also, a Fund may incur costs in connection with conversions between various currencies. Currency exchange rates may fluctuate significantly over short periods of time, causing a Fund’s NAV to fluctuate. Currency exchange rates are generally determined by the forces of supply and demand in the foreign exchange markets, actual or anticipated changes in interest rates, and other complex factors. Currency exchange rates also can be affected by the intervention of U.S. or foreign governments or central banks, or the failure to intervene, or by currency controls or political developments.

Spot Rates and Derivative Instruments. A Fund may conduct its foreign currency exchange transactions either at the spot (cash) rate prevailing in the foreign currency exchange market or by entering into forward foreign currency exchange contracts (forward contracts). (See Types of Investments – Derivatives.) These contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. Because foreign currency transactions occurring in the interbank market might involve substantially larger amounts than those involved in the use of such derivative instruments, a Fund could be disadvantaged by having to deal in the odd lot market for the underlying foreign currencies at prices that are less favorable than for round lots.

A Fund may enter into forward contracts for a variety of reasons, including for risk management (hedging) or for investment purposes.

When a Fund enters into a contract for the purchase or sale of a security denominated in a foreign currency or has been notified of a dividend or interest payment, it may desire to lock in the price of the security or the amount of the payment, usually in U.S. dollars, although it could desire to lock in the price of the security in another currency. By entering into a forward contract, a Fund would be able to protect itself against a possible loss resulting from an adverse change in the relationship between different currencies from the date the security is purchased or sold to the date on which payment is made or received or when the dividend or interest is actually received.

A Fund may enter into forward contracts when management of the Fund believes the currency of a particular foreign country may decline in value relative to another currency. When selling currencies forward in this fashion, a Fund may seek to hedge the value of foreign securities it holds against an adverse move in exchange rates. The precise matching of forward contract amounts and the value of securities involved generally will not be possible since the future value of securities in foreign currencies more than likely will change between the date the forward contract is entered into and the date it matures. The projection of short-term currency market movements is extremely difficult and successful execution of a short-term hedging strategy is highly uncertain.

This method of protecting the value of a Fund’s securities against a decline in the value of a currency does not eliminate fluctuations in the underlying prices of the securities. It simply establishes a rate of exchange that can be achieved at some point in time. Although forward contracts can be used to minimize the risk of loss due to a decline in value of hedged currency, they will also limit any potential gain that might result should the value of such currency increase.

A Fund may also enter into forward contracts when the Fund’s portfolio manager believes the currency of a particular country will increase in value relative to another currency. A Fund may buy currencies forward to gain exposure to a currency without incurring the additional costs of purchasing securities denominated in that currency.

For example, the combination of U.S. dollar-denominated instruments with long forward currency exchange contracts creates a position economically equivalent to a position in the foreign currency, in anticipation of an increase in the value of the foreign currency against the U.S. dollar. Conversely, the combination of U.S. dollar-denominated instruments with short forward currency exchange contracts is economically equivalent to borrowing the foreign currency for delivery at a specified date in the future, in anticipation of a decrease in the value of the foreign currency against the U.S. dollar.

Unanticipated changes in the currency exchange results could result in poorer performance for Funds that enter into these types of transactions.

A Fund may designate cash or securities in an amount equal to the value of the Fund’s total assets committed to consummating forward contracts entered into under the circumstance set forth above. If the value of the securities declines, additional cash or securities will be designated on a daily basis so that the value of the cash or securities will equal the amount of the Fund’s commitments on such contracts.

At maturity of a forward contract, a Fund may either deliver (if a contract to sell) or take delivery of (if a contract to buy) the foreign currency or terminate its contractual obligation by entering into an offsetting contract with the same currency trader, having the same maturity date, and covering the same amount of foreign currency.

Statement of Additional Information – [_________, 2022]

Table of Contents

If a Fund engages in an offsetting transaction, it will incur a gain or loss to the extent there has been movement in forward contract prices. If a Fund engages in an offsetting transaction, it may subsequently enter into a new forward contract to buy or sell the foreign currency.

Although a Fund values its assets each business day in terms of U.S. dollars, it may not intend to convert its foreign currencies into U.S. dollars on a daily basis. However, it will do so from time to time, and such conversions involve certain currency conversion costs. Although foreign exchange dealers do not charge a fee for conversion, they do realize a profit based on the difference (spread) between the prices at which they buy and sell various currencies. Thus, a dealer may offer to sell a foreign currency to a Fund at one rate, while offering a lesser rate of exchange should a Fund desire to resell that currency to the dealer.

It is possible, under certain circumstances, including entering into forward currency contracts for investment purposes, that a Fund will be required to limit or restructure its forward contract currency transactions to qualify as a “regulated investment company” under the Code.

Options on Foreign Currencies. A Fund may buy put and call options and write covered call and cash-secured put options on foreign currencies for hedging purposes and to gain exposure to foreign currencies. For example, a decline in the dollar value of a foreign currency in which securities are denominated will reduce the dollar value of such securities, even if their value in the foreign currency remains constant. In order to protect against the diminutions in the value of securities, a Fund may buy put options on the foreign currency. If the value of the currency does decline, a Fund would have the right to sell the currency for a fixed amount in dollars and would thereby offset, in whole or in part, the adverse effect on its portfolio that otherwise would have resulted.

Conversely, where a change in the dollar value of a currency would increase the cost of securities a Fund plans to buy, or where a Fund would benefit from increased exposure to the currency, a Fund may buy call options on the foreign currency, giving it the right to purchase the currency for a fixed amount in dollars. The purchase of the options could offset, at least partially, the changes in exchange rates.

As in the case of other types of options, however, the benefit to a Fund derived from purchases of foreign currency options would be reduced by the amount of the premium and related transaction costs. In addition, where currency exchange rates do not move in the direction or to the extent anticipated, a Fund could sustain losses on transactions in foreign currency options that would require it to forego a portion or all of the benefits of advantageous changes in rates.

A Fund may write options on foreign currencies for similar purposes. For example, when a Fund anticipates a decline in the dollar value of foreign-denominated securities due to adverse fluctuations in exchange rates, it could, instead of purchasing a put option, write a call option on the relevant currency, giving the option holder the right to purchase that currency from the Fund for a fixed amount in dollars. If the expected decline occurs, the option would most likely not be exercised and the diminution in value of securities would be offset, at least partially, by the amount of the premium received.

Similarly, instead of purchasing a call option when a foreign currency is expected to appreciate, a Fund could write a put option on the relevant currency, giving the option holder the right to that currency from the Fund for a fixed amount in dollars. If rates move in the manner projected, the put option would expire unexercised and allow the Fund to hedge increased cost up to the amount of the premium.

As in the case of other types of options, however, the writing of a foreign currency option will constitute only a partial hedge up to the amount of the premium, and only if rates move in the expected direction. If this does not occur, the option may be exercised and the Fund would be required to buy or sell the underlying currency at a loss that may not be offset by the amount of the premium. Through the writing of options on foreign currencies, the Fund also may be required to forego all or a portion of the benefits that might otherwise have been obtained from favorable movements on exchange rates.

An option written on foreign currencies is covered if a Fund holds currency sufficient to cover the option or has an absolute and immediate right to acquire that currency without additional cash consideration upon conversion of assets denominated in that currency or exchange of other currency held in its portfolio. An option writer could lose amounts substantially in excess of its initial investments, due to the margin and collateral requirements associated with such positions.

Options on foreign currencies are traded through financial institutions acting as market-makers, although foreign currency options also are traded on certain national securities exchanges, such as the Philadelphia Stock Exchange and the Chicago Board Options Exchange, subject to SEC regulation. In an over-the-counter trading environment, many of the protections afforded to exchange participants will not be available. For example, there are no daily price fluctuation limits, and adverse market movements could therefore continue to an unlimited extent over a period of time. Although the purchaser of an option cannot lose more than the amount of the premium plus related transaction costs, this entire amount could be lost.

Statement of Additional Information – [_________, 2022]

Table of Contents

Foreign currency option positions entered into on a national securities exchange are cleared and guaranteed by the OCC, thereby reducing the risk of counterparty default. Further, a liquid secondary market in options traded on a national securities exchange may be more readily available than in the over-the-counter market, potentially permitting a Fund to liquidate open positions at a profit prior to exercise or expiration, or to limit losses in the event of adverse market movements.

Foreign Currency Futures and Related Options. A Fund may enter into currency futures contracts to buy or sell currencies. It also may buy put and call options and write covered call and cash-secured put options on currency futures. Currency futures contracts are similar to currency forward contracts, except that they are traded on exchanges (and have margin requirements) and are standardized as to contract size and delivery date. Most currency futures call for payment of delivery in U.S. dollars. A Fund may use currency futures for the same purposes as currency forward contracts, subject to CFTC limitations.

Currency futures and options on futures values can be expected to correlate with exchange rates, but will not reflect other factors that may affect the value of the Fund’s investments. A currency hedge, for example, should protect a Yen-denominated bond against a decline in the Yen, but will not protect a Fund against price decline if the issuer’s creditworthiness deteriorates. Because the value of a Fund’s investments denominated in foreign currency will change in response to many factors other than exchange rates, it may not be possible to match the amount of a forward contract to the value of a Fund’s investments denominated in that currency over time.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with foreign currency transactions include: Foreign Currency Risk, Derivatives Risk, Interest Rate Risk, and Liquidity Risk.

Foreign Securities

The Funds may invest in foreign securities to the extent described in their prospectuses, and may obtain exposures to foreign securities through depository receipts, as described below. Foreign securities include debt, equity and derivative securities that a Fund’s portfolio manager(s), as the case may be, determines are “foreign” based on the consideration of an issuer’s country of organization, domicile, its principal place of business, its primary stock exchange listing, the source of its revenue or other factors. A Fund’s investments in foreign markets, may include issuers in emerging markets, as well as frontier markets, each of which carry heightened risks as compared with investments in other typical foreign markets. Unless otherwise stated in a Fund’s prospectus, emerging market countries are generally those either defined by World Bank-defined per capita income brackets or determined to be an emerging market based on the Fund portfolio manager’s qualitative judgments about a country’s level of economic and institutional development, among other factors. Frontier market countries generally have smaller economies and even less developed capital markets than typical emerging market countries (which themselves have increased investment risk relative to investing in more developed markets) and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries. Foreign securities may be structured as fixed-, variable- or floating-rate obligations or as zero-coupon, pay-in-kind and step-coupon securities and may be privately placed or publicly offered. See Types of Investments — Variable- and Floating-Rate Obligations, — Debt Obligations - Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and — Private Placement and Other Restricted Securities for more information.

Due to the potential for foreign withholding taxes, MSCI publishes two versions of its indices reflecting the reinvestment of dividends using two different methodologies: gross dividends and net dividends. While both versions reflect reinvested dividends, they differ with respect to the manner in which taxes associated with dividend payments are treated. In calculating the net dividends version, MSCI incorporates reinvested dividends applying the withholding tax rate applicable to foreign non-resident institutional investors that do not benefit from double taxation treaties. The Investment Manager believes that the net dividends version of MSCI indices better reflects the returns U.S. investors might expect were they to invest directly in the component securities of an MSCI index.

There is 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 such shares are voted. This is referred to as “share blocking.” The blocking period can last up to several weeks. Share blocking may prevent a 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. As a consequence of these restrictions, the Investment Manager, on behalf of a Fund, may abstain from voting proxies in markets that require share blocking.

Foreign securities may include depositary receipts, such as American Depositary Receipts (ADRs), European Depositary Receipts (EDRs) and Global Depositary Receipts (GDRs). ADRs are U.S. dollar-denominated receipts issued in registered form by a domestic bank or trust company that evidence ownership of underlying securities issued by a foreign issuer. EDRs are foreign currency-denominated receipts issued in Europe, typically by foreign banks or trust companies and foreign branches of domestic banks, that evidence ownership of foreign or domestic securities. GDRs are receipts structured similarly to ADRs and EDRs and are marketed globally. Depositary receipts will not necessarily be denominated in the same currency as their underlying securities. In general, ADRs, in registered form, are designed for use in the U.S. securities markets, and EDRs, in

Statement of Additional Information – [_________, 2022]

Table of Contents

bearer form, are designed for use in European securities markets. GDRs are tradable both in the United States and in Europe and are designed for use throughout the world. A Fund may invest in depositary receipts through “sponsored” or “unsponsored” facilities. A sponsored facility is established jointly by the issuer of the underlying security and a depositary, whereas a depositary may establish an unsponsored facility without participation by the issuer of the deposited security. Holders of unsponsored depositary receipts generally bear all the costs of such facilities and the depositary of an unsponsored facility frequently is under no obligation to distribute interest holder communications received from the issuer of the deposited security or to pass through voting rights to the holders of such receipts in respect of the deposited securities. The issuers of unsponsored depositary receipts are not obligated to disclose material information in the United States, and, therefore, there may be limited information available regarding such issuers and/or limited correlation between available information and the market value of the depositary receipts.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with foreign securities include: Emerging Markets Securities Risk, Foreign Currency Risk, Foreign Securities Risk, Frontier Market Risk, Geographic Focus Risk, Issuer Risk and Market Risk.

Guaranteed Investment Contracts (Funding Agreements)

Guaranteed investment contracts, or funding agreements, are short-term, privately placed debt instruments issued by insurance companies. Pursuant to such contracts, a Fund may make cash contributions to a deposit fund of the insurance company’s general account. The insurance company then credits to a Fund payments at negotiated, floating or fixed interest rates. A Fund will purchase guaranteed investment contracts only from issuers that, at the time of purchase, meet certain credit and quality standards. In general, guaranteed investment contracts are not assignable or transferable without the permission of the issuing insurance companies, and an active secondary market does not exist for these investments. In addition, the issuer may not be able to pay the principal amount to a Fund on seven days’ notice or less, at which time the investment may be considered illiquid. See Types of Investments – Illiquid Investments.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with guaranteed investment contracts (funding agreements) include: Credit Risk and Liquidity Risk.

High-yield, or low and below investment grade securities (below investment grade securities are also known as “junk bonds”) are debt securities with the lowest investment grade rating (e.g., BBB by S&P and Fitch or Baa by Moody’s), that are below investment grade (e.g., lower than BBB by S&P and Fitch or Baa by Moody’s) or that are unrated but determined by a Fund’s portfolio manager to be of comparable quality. These types of securities may be issued to fund corporate transactions or restructurings, such as leveraged buyouts, mergers, acquisitions, debt reclassifications or similar events, are more speculative in nature than securities with higher ratings and tend to be more sensitive to credit risk, particularly during a downturn in the economy. These types of securities generally are issued by unseasoned companies without long track records of sales and earnings, or by companies or municipalities that have questionable credit strength. High-yield securities and comparable unrated securities: (i) likely will have some quality and protective characteristics that, in the judgment of one or more NRSROs, are outweighed by large uncertainties or major risk exposures to adverse conditions; (ii) are speculative with respect to the issuer’s capacity to pay interest and repay principal in accordance with the terms of the obligation; and (iii) may have a less liquid secondary market, potentially making it difficult to value or sell such securities. Credit ratings issued by credit rating agencies are designed to evaluate the safety of principal and interest payments of rated securities. They do not, however, evaluate the market value risk of lower-quality securities and, therefore, may not fully reflect the true risks of an investment. In addition, credit rating agencies may or may not make timely changes in a rating to reflect changes in the economy or in the condition of the issuer that affect the market value of the securities. Consequently, credit ratings are used only as a preliminary indicator of investment quality. High-yield securities may be structured as fixed-, variable- or floating-rate obligations or as zero-coupon, pay-in-kind and step-coupon securities and may be privately placed or publicly offered. See Types of Investments – Variable- and Floating-Rate Obligations, – Debt Obligations – Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and – Private Placement and Other Restricted Securities for more information.

The rates of return on these types of securities generally are higher than the rates of return available on more highly rated securities, but generally involve greater volatility of price and risk of loss of principal and income, including the possibility of default by or insolvency of the issuers of such securities. Accordingly, a Fund may be more dependent on the Investment Manager’s (or, if applicable, a subadviser’s) credit analysis with respect to these types of securities than is the case for more highly rated securities.

Table of Contents

The market values of certain high-yield securities and comparable unrated securities tend to be more sensitive to individual corporate developments and changes in economic conditions than are the market values of more highly rated securities. In addition, issuers of high-yield and comparable unrated securities often are highly leveraged and may not have more traditional methods of financing available to them, so that their ability to service their debt obligations during an economic downturn or during sustained periods of rising interest rates may be impaired.

The risk of loss due to default is greater for high-yield and comparable unrated securities than it is for higher rated securities because high-yield securities and comparable unrated securities generally are unsecured and frequently are subordinated to more senior indebtedness. A Fund may incur additional expenses to the extent that it is required to seek recovery upon a default in the payment of principal or interest on its holdings of such securities. The existence of limited markets for lower-rated debt securities may diminish a Fund’s ability to: (i) obtain accurate market quotations for purposes of valuing such securities and calculating portfolio net asset value; and (ii) sell the securities at fair market value either to meet redemption requests or to respond to changes in the economy or in financial markets.

Many lower-rated securities are not registered for offer and sale to the public under the 1933 Act. Investments in these restricted securities may be determined to be liquid (able to be sold or disposed of in current market conditions in seven days or less without the sales or dispositions significantly changing the market value of the investment) pursuant to the Funds’ liquidity risk management program. A Fund may not purchase or otherwise acquire any illiquid investments if, immediately after the acquisition, the value of illiquid investments held by the Fund would exceed 15% of the Fund’s net assets. A Fund is not otherwise subject to any limitation on its ability to invest in restricted securities. Restricted securities may be less liquid than other lower-rated securities, potentially making it difficult to value or sell such securities.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with high-yield securities include: Credit Risk, Interest Rate Risk, High-Yield Securities Risk and Prepayment and Extension Risk.

Illiquid Investments

An illiquid investment is any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Some securities, such as those not registered under U.S. securities laws, cannot be sold in public transactions. Some securities are deemed to be illiquid because they are subject to contractual or legal restrictions on resale. Subject to its investment policies, a Fund may invest in illiquid investments and may invest in certain restricted securities that are deemed to be illiquid investments at the time of purchase.

Although one or more of the other risks described in this SAI may also apply, the risk typically associated with illiquid investments include: Liquidity Risk.

Inflation-Protected Securities

Inflation is a general rise in prices of goods and services. Inflation erodes the purchasing power of an investor’s assets. For example, if an investment provides a total return of 7% in a given year and inflation is 3% during that period, the inflation-adjusted, or real, return is 4%. Inflation-protected securities are debt securities whose principal and/or interest payments are adjusted for inflation, unlike debt securities that make fixed principal and interest payments. One type of inflation-protected debt security is issued by the U.S. Treasury. The principal of these securities is adjusted for inflation as indicated by the Consumer Price Index (CPI) for urban consumers and interest is paid on the adjusted amount. The CPI is a measurement of changes in the cost of living, made up of components such as housing, food, transportation and energy.

If the CPI falls, the principal value of inflation-protected securities will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Conversely, if the CPI rises, the principal value of inflation-protected securities will be adjusted upward, and consequently the interest payable on these securities will be increased. Repayment of the original bond principal upon maturity is guaranteed in the case of U.S. Treasury inflation-protected securities, even during a period of deflation. However, the current market value of the inflation-protected securities is not guaranteed and will fluctuate. Other inflation-indexed securities include inflation-related bonds, which may or may not provide a similar guarantee. If a guarantee of principal is not provided, the adjusted principal value of the bond repaid at maturity may be less than the original principal.

Other issuers of inflation-protected debt securities include other U.S. government agencies or instrumentalities, corporations and foreign governments. There can be no assurance that the CPI or any foreign inflation index will accurately measure the real rate of inflation in the prices of goods and services. Moreover, there can be no assurance that the rate of inflation in a foreign country will be correlated to the rate of inflation in the United States. If interest rates rise due to reasons other than inflation (for example, due to changes in currency exchange rates), investors in these securities may not be protected to the extent that the increase is not reflected in the bond’s inflation measure.

Statement of Additional Information – [_________, 2022]

Table of Contents

Any increase in principal for an inflation-protected security resulting from inflation adjustments is considered by IRS regulations to be taxable income in the year it occurs. For direct holders of an inflation-protected security, this means that taxes must be paid on principal adjustments even though these amounts are not received until the bond matures. Similarly, a Fund treated as a regulated investment company (RIC) under the Code that holds these securities distributes both interest income and the income attributable to principal adjustments in the form of cash or reinvested shares, which are taxable to shareholders.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with inflation-protected securities include: Inflation-Protected Securities Risk, Interest Rate Risk and Market Risk. In addition, inflation-protected securities issued by non-U.S. government agencies or instrumentalities are subject to Credit Risk.

Initial Public Offerings

A Fund may invest in initial public offerings (IPOs) of common stock or other primary or secondary syndicated offerings of equity or debt securities issued by a corporate issuer. Fixed income funds frequently invest in these types of offerings of debt securities. A purchase of IPO securities often involves higher transaction costs than those associated with the purchase of securities already traded on exchanges or markets. A Fund may hold IPO securities for a period of time, or may sell them soon after the purchase. Investments in IPOs could have a magnified impact — either positive or negative — on a Fund’s performance while the Fund’s assets are relatively small. The impact of an IPO on a Fund’s performance may tend to diminish as the Fund’s assets grow. In circumstances when investments in IPOs make a significant contribution to a Fund’s performance, there can be no assurance that similar contributions from IPOs will continue in the future.

Although one or more risks described in this SAI may also apply, the risks typically associated with IPOs include: IPO Risk, Issuer Risk, Liquidity Risk, Market Risk and Small Company Securities Risk.

Investments in Other Investment Companies (Including Other ETFs)

Investing in other investment companies may be a means by which a Fund seeks to achieve its investment objective. A Fund may invest in securities issued by other investment companies within the limits prescribed by the 1940 Act, the rules and regulations thereunder and any exemptive relief currently or in the future available to a Fund. These securities include shares of other affiliated or unaffiliated open-end investment companies (i.e., mutual funds), closed-end funds, exchange-traded funds (ETFs), UCITS funds (pooled investment vehicles established in accordance with the Undertaking for Collective Investment in Transferable Securities) and business development companies.

Except with respect to funds structured as funds-of-funds or so-called master/feeder funds or other funds whose strategies otherwise allow such investments, the 1940 Act generally requires that a fund limit its investments in another investment company or series thereof so that, as determined at the time a securities purchase is made: (i) no more than 5% of the value of its total assets will be invested in the securities of any one investment company; (ii) no more than 10% of the value of its total assets will be invested in the aggregate in securities of other investment companies; and (iii) no more than 3% of the outstanding voting stock of any one investment company or series thereof will be owned by a fund or by companies controlled by a fund. Such other investment companies may include ETFs, which are shares of publicly traded unit investment trusts, open-end funds or depositary receipts that may be passively managed (e.g., they seek to track the performance of specific indexes or companies in related industries) or they may be actively managed, such as the Funds. The SEC has granted orders for exemptive relief to certain ETFs (including the Funds) that permit investments in those ETFs by certain other registered investment companies in excess of these limits.

ETFs are listed on an exchange and trade in the secondary market on a per-share basis, which allows investors to purchase and sell ETF shares at their market price throughout the day. Certain ETFs, such as passively managed ETFs, hold portfolios of securities that are designed to replicate, as closely as possible before expenses, the price and yield of a specified market index. The performance results of these ETFs will not replicate exactly the performance of the pertinent index due to transaction and other expenses, including fees to service providers borne by ETFs. ETF shares are sold and redeemed at net asset value only in large blocks called creation units. The Funds’ ability to redeem creation units may be limited by the 1940 Act, which provides that the Funds will not be obligated to redeem shares in an amount exceeding one percent of their total outstanding securities during any period of less than 30 days.

Although a Fund may derive certain advantages from being able to invest in shares of other investment companies, such as to be fully invested, there may be potential disadvantages. Investing in other investment companies may result in higher fees and expenses for a Fund and its shareholders. A shareholder may be charged fees not only on Fund shares held directly but also on the investment company shares that a Fund purchases. Because these investment companies may invest in other securities, they are also subject to the risks associated with a variety of investment instruments as described in this SAI.

Statement of Additional Information – [_________, 2022]

Table of Contents

Under the 1940 Act and rules and regulations thereunder, a Fund may purchase shares of affiliated funds, subject to certain conditions. Investing in affiliated funds presents certain actual or potential conflicts of interest. For more information about such actual and potential conflicts of interest, see Investment Management and Other Services – Other Roles and Relationships of Ameriprise Financial and its Affiliates – Certain Conflicts of Interest.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with the securities of other investment companies include: Investing in Other Funds Risk, Issuer Risk and Market Risk.

Listed Private Equity Funds

A Fund may invest directly in listed private equity funds, which may include, among others, business development companies, investment holding companies, publicly traded limited partnership interests (common units), publicly traded venture capital funds, publicly traded venture capital trusts, publicly traded private equity funds, publicly traded private equity investment trusts, publicly traded closed-end funds, publicly traded financial institutions that lend to or invest in privately held companies and any other publicly traded vehicle whose purpose is to invest in privately held companies.

A Fund may invest in listed private equity funds that hold investments in a wide array of businesses and industries at various stages of development, from early stage to later stage to fully mature businesses. A Fund may invest in listed private equity funds that emphasize making equity and equity-like (preferred stock, convertible stock and warrants) investments in later stage to mature businesses, or may invest in listed private equity funds making debt investments or investments in companies at other stages of development. In addition, a Fund may invest in the common stock of closed-end management investment companies, including business development companies that invest in securities of listed private equity companies.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with investment in listed private equity funds include: Credit Risk, Liquidity Risk, Market Risk, Sector Risk, and Valuation Risk.

Money Market Instruments

Money market instruments include cash equivalents and short-term debt obligations which include: (i) bank obligations, including certificates of deposit (CDs), time deposits and bankers’ acceptances, and letters of credit of banks or savings and loan associations having capital surplus and undivided profits (as of the date of its most recently published annual financial statements) in excess of $100 million (or the equivalent in the instance of a foreign branch of a U.S. bank) at the date of investment; (ii) funding agreements; (iii) repurchase agreements; (iv) obligations of the United States, foreign countries and supranational entities, and each of their subdivisions, agencies and instrumentalities; (v) certain corporate debt securities, such as commercial paper, short-term corporate obligations and extendible commercial notes; (vi) participation interests; and (vii) municipal securities. Money market instruments may be structured as fixed-, variable- or floating-rate obligations and may be privately placed or publicly offered. A Fund may also invest in affiliated and unaffiliated money market mutual funds, which invest primarily in money market instruments. See Types of Investments — Variable- and Floating-Rate Obligations and — Private Placement and Other Restricted Securities for more information.

With respect to money market securities, certain U.S. Government obligations are backed or insured by the U.S. Government, its agencies or its instrumentalities. Other money market securities are backed only by the claims paying ability or creditworthiness of the issuer.

Bankers’ acceptances are marketable short-term credit instruments used to finance the import, export, transfer or storage of goods. They are termed “accepted” when a bank unconditionally guarantees their payment at maturity.

The Fund may invest cash in, or hold as collateral for certain investments, shares of registered or unregistered money market funds, including funds advised by the Investment Manager or its affiliates. These funds are not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. The Fund and its shareholders indirectly bear a portion of the expenses of any money market fund or other fund in which the Fund may invest.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with money market instruments include: Credit Risk, Inflation Risk, Interest Rate Risk, Issuer Risk and Money Market Fund Risk.

Mortgage-Backed Securities

Mortgage-backed securities are a type of asset-backed security that represent interests in, or debt instruments backed by, pools of underlying mortgages. In some cases, these underlying mortgages may be insured or guaranteed by the U.S. Government or its agencies. Mortgage-backed securities entitle the security holders to receive distributions that are tied to the payments made on the underlying mortgage collateral (less fees paid to the originator, servicer, or other parties, and fees paid for credit enhancement), so that the payments made on the underlying mortgage collateral effectively pass through to such security holders. Mortgage-backed securities are created when mortgage originators (or mortgage loan sellers who have purchased mortgage loans from mortgage loan originators) sell the underlying mortgages to a special purpose entity in a process called a securitization. The special purpose entity issues securities that are backed by the payments on the underlying mortgage loans,

and have a minimum denomination and specific term. A decline or flattening of housing values may cause delinquencies in mortgages (especially sub-prime or non-prime mortgages) underlying mortgage-backed securities and thereby adversely affect the ability of the mortgage-backed securities issuer to make principal and/or interest payments to mortgage-backed securities holders. Mortgage-backed securities may be structured as fixed-, variable- or floating-rate obligations or as zero-coupon, pay-in-kind and step-coupon securities and may be privately placed or publicly offered. See Types of Investments — Variable- and Floating-Rate Obligations, — Debt Obligations - Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and — Private Placement and Other Restricted Securities for more information.

Mortgage-backed securities may be issued or guaranteed by GNMA (also known as Ginnie Mae), FNMA (also known as Fannie Mae), or FHLMC (also known as Freddie Mac), but also may be issued or guaranteed by other issuers, including private companies. GNMA is a government-owned corporation that is an agency of the U.S. Department of Housing and Urban Development. It guarantees, with the full faith and credit of the United States, full and timely payment of all monthly principal and interest on its mortgage-backed securities. Until recently, FNMA and FHLMC were government-sponsored corporations owned entirely by private stockholders. Both issue mortgage-related securities that contain guarantees as to timely payment of interest and principal but that are not backed by the full faith and credit of the U.S. Government. The value of the companies’ securities fell sharply in 2008 due to concerns that the firms did not have sufficient capital to offset losses. The U.S. Treasury has historically had the authority to purchase obligations of Fannie Mae and Freddie Mac. In addition, in 2008, due to capitalization concerns, Congress provided the U.S. Treasury with additional authority to lend Fannie Mae and Freddie Mac emergency funds and to purchase the companies’ stock, as described below. In September 2008, the U.S. Treasury and the Federal Housing Finance Agency (FHFA) announced that Fannie Mae and Freddie Mac had been placed in conservatorship.

In the past Fannie Mae and Freddie Mac have received significant capital support through U.S. Treasury preferred stock purchases and Federal Reserve purchases of their mortgage-backed securities. There can be no assurance that these or other agencies of the government will provide such support in the future. The future status of Fannie Mae or Freddie Mac could be impacted by, among other things, the actions taken and restrictions placed on Fannie Mae or Freddie Mac by the FHFA in its role as conservator, the restrictions placed on Fannie Mae’s or Freddie Mac’s operations and activities under the senior stock purchase agreements, market responses to developments at Fannie Mae or Freddie Mac, and future legislative and regulatory action that alters the operations, ownership structure and/or mission of Fannie Mae or Freddie Mac, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Fannie Mae and Freddie Mac.

The FHFA recently announced plans to consider taking Fannie Mae and Freddie Mac out of conservatorship. Should Fannie Mae and Freddie Mac be taken out of conservatorship, it is unclear whether the U.S. Treasury would continue to enforce its rights or perform its obligations under the senior stock purchase agreements. It is also unclear how the capital structure of Fannie Mae and Freddie Mac would be constructed post-conservatorship, and what effects, if any, the privatization of the enterprises will have on their creditworthiness and guarantees of certain mortgage-backed securities. Accordingly, should the FHFA take the enterprises out of conservatorship, there could be an adverse impact on the value of securities guaranteed by Fannie Mae and Freddie Mac which could cause a Fund’s shares to lose value.

Stripped mortgage-backed securities are a type of mortgage-backed security that receives differing proportions of the interest and principal payments from the underlying assets. Generally, there are two classes of stripped mortgage-backed securities: Interest Only (IO) and Principal Only (PO). IOs entitle the holder to receive distributions consisting of all or a portion of the interest on the underlying pool of mortgage loans or mortgage-backed securities. POs entitle the holder to receive distributions consisting of all or a portion of the principal of the underlying pool of mortgage loans or mortgage-backed securities. See Types of Investments — Debt Obligations - Stripped Securities for more information.

Collateralized Mortgage Obligations (CMOs) are hybrid mortgage-related instruments issued by special purpose entities secured by pools of mortgage loans or other mortgage-related securities, such as mortgage pass-through securities or stripped mortgage-backed securities. CMOs may be structured into multiple classes, often referred to as “tranches,” with each class bearing a different stated maturity and entitled to a different schedule for payments of principal and interest, including prepayments. Principal prepayments on collateral underlying a CMO may cause it to be retired substantially earlier than its stated maturity or final distribution dates, resulting in a loss of all or part of the premium if any has been paid. The yield characteristics of mortgage-backed securities differ from those of other debt securities. Among the differences are that interest and principal payments are made more frequently on mortgage-backed securities, usually monthly, and principal may be repaid at any time. These factors may reduce the expected yield. Interest is paid or accrues on all classes of the CMOs on a periodic basis. The principal and interest payments on the underlying mortgage assets may be allocated among the various classes of CMOs in several ways. Typically, payments of principal, including any prepayments, on the underlying mortgage assets are applied to the classes in the order of their respective stated maturities or final distribution dates, so that no payment of principal is made on CMOs of a class until all CMOs of other classes having earlier stated maturities or final distribution dates have been paid in full.

Commercial mortgage-backed securities (CMBS) are a specific type of mortgage-backed security collateralized by a pool of mortgages on commercial real estate.

Table of Contents

CMO residuals are mortgage securities issued by agencies or instrumentalities of the U.S. Government or by private originators of, or investors in, mortgage loans, including savings and loan associations, homebuilders, mortgage banks, commercial banks, investment banks and special purpose entities of the foregoing. The cash flow generated by the mortgage assets underlying a series of CMOs is applied first to make required payments of principal and interest on the CMOs and second to pay the related administrative expenses and any management fee of the issuer. The residual in a CMO structure generally represents the interest in any excess cash flow remaining after making the foregoing payments. Each payment of such excess cash flow to a holder of the related CMO residual represents income and/or a return of capital. The amount of residual cash flow resulting from a CMO will depend on, among other things, the characteristics of the mortgage assets, the coupon rate of each class of CMO, prevailing interest rates, the amount of administrative expenses and the pre-payment experience on the mortgage assets. In particular, the yield to maturity on CMO residuals is extremely sensitive to pre-payments on the related underlying mortgage assets, in the same manner as an interest-only (“IO”) class of stripped mortgage-backed securities. In addition, if a series of a CMO includes a class that bears interest at an adjustable rate, the yield to maturity on the related CMO residual will also be extremely sensitive to changes in the level of the index upon which interest rate adjustments are based. As described below with respect to stripped mortgage-backed securities, in certain circumstances an ETF may fail to recoup fully its initial investment in a CMO residual. CMO residuals are generally purchased and sold by institutional investors through several investment banking firms acting as brokers or dealers. Transactions in CMO residuals are generally completed only after careful review of the characteristics of the securities in question. In addition, CMO residuals may or, pursuant to an exemption therefrom, may not have been registered under the 1933 Act. CMO residuals, whether or not registered under the 1933 Act, may be subject to certain restrictions on transferability, and may be deemed “illiquid” and subject to a Fund’s limitations on investment in illiquid investments.

Mortgage pass-through securities are interests in pools of mortgage-related securities that differ from other forms of debt securities, which normally provide for periodic payment of interest in fixed amounts with principal payments at maturity or specified call dates. Instead, these securities provide a monthly payment which consists of both interest and principal payments. In effect, these payments are a “pass-through” of the monthly payments made by the individual borrowers on their residential or commercial mortgage loans, net of any fees paid to the issuer or guarantor of such securities. Additional payments are caused by repayments of principal resulting from the sale of the underlying property, refinancing or foreclosure, net of fees or costs which may be incurred. Some mortgage-related securities (such as securities issued by the GNMA) are described as “modified pass-through.” These securities entitle the holder to receive all interest and principal payments owed on the mortgage pool, net of certain fees, at the scheduled payment dates regardless of whether or not the mortgagor actually makes the payment.

REMICs are entities that own mortgages and elect REMIC status under the Code and, like CMOs, issue debt obligations collateralized by underlying mortgage assets that have characteristics similar to those issued by CMOs.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with mortgage- and asset-backed securities include: Credit Risk, Interest Rate Risk, Issuer Risk, Liquidity Risk, Mortgage- and Other Asset-Backed Securities Risk, Prepayment and Extension Risk and Reinvestment Risk.

Municipal Securities

Municipal securities include debt obligations issued by governmental entities, including states, political subdivisions, agencies, instrumentalities, and authorities, as well as U.S. territories, commonwealths and possessions (such as Guam, Puerto Rico and the U.S. Virgin Islands) and their political subdivisions, agencies, instrumentalities, and authorities, to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities.

Municipal securities may include municipal bonds, municipal notes and municipal leases, which are described below. Municipal bonds are debt obligations of a governmental entity that obligate the municipality to pay the holder a specified sum of money at specified intervals and to repay the principal amount of the loan at maturity. Municipal securities can be classified into two principal categories, including “general obligation” bonds and other securities and “revenue” bonds and other securities. General obligation bonds are secured by the issuer’s full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source, such as the user of the facility being financed. Municipal securities also may include “moral obligation” securities, which normally are issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the governmental entity that created the special purpose public authority. Municipal securities may be structured as fixed-, variable- or floating-rate obligations or as zero-coupon, pay-in-kind and step-coupon securities and may be privately placed or publicly offered. See Types of Investments – Variable- and Floating-Rate Obligations, – Debt Obligations – Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and – Private Placement and Other Restricted Securities for more information.

Table of Contents

Municipal notes may be issued by governmental entities and other tax-exempt issuers in order to finance short-term cash needs or, occasionally, to finance construction. Most municipal notes are general obligations of the issuing entity payable from taxes or designated revenues expected to be received within the relevant fiscal period. Municipal notes generally have maturities of one year or less. Municipal notes can be subdivided into two sub-categories: (i) municipal commercial paper and (ii) municipal demand obligations.

Municipal commercial paper typically consists of very short-term unsecured negotiable promissory notes that are sold, for example, to meet seasonal working capital or interim construction financing needs of a governmental entity or agency. While these obligations are intended to be paid from general revenues or refinanced with long-term debt, they frequently are backed by letters of credit, lending agreements, note repurchase agreements or other credit facility agreements offered by banks or institutions. See Types of Investments – Commercial Paper for more information.

Municipal demand obligations can be subdivided into two general types: variable rate demand notes and master demand obligations. Variable rate demand notes are tax-exempt municipal obligations or participation interests that provide for a periodic adjustment in the interest rate paid on the notes. They permit the holder to demand payment of the notes, or to demand purchase of the notes at a purchase price equal to the unpaid principal balance, plus accrued interest either directly by the issuer or by drawing on a bank letter of credit or guaranty issued with respect to such note. The issuer of the municipal obligation may have a corresponding right to prepay at its discretion the outstanding principal of the note plus accrued interest upon notice comparable to that required for the holder to demand payment. The variable rate demand notes in which a Fund may invest are payable, or are subject to purchase, on demand, usually on notice of seven calendar days or less. The terms of the notes generally provide that interest rates are adjustable at intervals ranging from daily to six months.

Master demand obligations are tax-exempt municipal obligations that provide for a periodic adjustment in the interest rate paid and permit daily changes in the amount borrowed. The interest on such obligations is, in the opinion of counsel for the borrower, excluded from gross income for U.S. federal income tax purposes (but not necessarily for alternative minimum tax purposes). Although there is no secondary market for master demand obligations, such obligations are considered by a Fund to be liquid because they are payable upon demand.

Municipal lease obligations are participations in privately arranged loans to state or local government borrowers and may take the form of a lease, an installment purchase, or a conditional sales contract. They are issued by state and local governments and authorities to acquire land, equipment, and facilities. An investor may purchase these obligations directly, or it may purchase participation interests in such obligations. In general, municipal lease obligations are unrated, in which case they will be determined by a Fund’s portfolio manager to be of comparable quality at the time of purchase to rated instruments that may be acquired by a Fund. Frequently, privately arranged loans have variable interest rates and may be backed by a bank letter of credit. In other cases, they may be unsecured or may be secured by assets not easily liquidated.

Moreover, such loans in most cases are not backed by the taxing authority of the issuers and may have limited marketability or may be marketable only by virtue of a provision requiring repayment following demand by the lender.

Municipal leases may be subject to greater risks than general obligation or revenue bonds. State constitutions and statutes set forth requirements that states or municipalities must meet in order to issue municipal obligations. Municipal leases may contain a covenant by the state or municipality to budget for and make payments due under the obligation. Certain municipal leases may, however, provide that the issuer is not obligated to make payments on the obligation in future years unless funds have been appropriated for this purpose each year.

Although lease obligations do not constitute general obligations of the municipal issuer to which the government’s taxing power is pledged, a lease obligation ordinarily is backed by the government’s covenant to budget for, appropriate, and make the payments due under the lease obligation. However, certain lease obligations contain “non-appropriation” clauses that provide that the government has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a periodic basis. In the case of a “non-appropriation” lease, a Fund’s ability to recover under the lease in the event of non-appropriation or default likely will be limited to the repossession of the leased property in the event that foreclosure proves difficult.

Tender option bonds are municipal securities having relatively long maturities and bearing interest at a fixed interest rate substantially higher than prevailing short-term tax-exempt rates that is coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, to grant the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. The financial institution receives periodic fees equal to the difference between the municipal security’s coupon rate and the rate that would cause the security to trade at face value on the date of determination.

There are variations in the quality of municipal securities, both within a particular classification and between classifications, and the rates of return on municipal securities can depend on a variety of factors, including general money market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity

Statement of Additional Information – [_________, 2022]

Table of Contents

of the obligation, and the rating of the issue. The ratings of NRSROs represent their opinions as to the quality of municipal securities. It should be emphasized, however, that these ratings are general and are not absolute standards of quality, and municipal securities with the same maturity, interest rate, and rating may have different rates of return while municipal securities of the same maturity and interest rate with different ratings may have the same rate of return. The municipal bond market is characterized by a large number of different issuers, many having smaller sized bond issues, and a wide choice of different maturities within each issue. For these reasons, most municipal bonds do not trade on a daily basis and many trade only rarely. Because many of these bonds trade infrequently, the spread between the bid and offer may be wider and the time needed to develop a bid or an offer may be longer than for other security markets. See Appendix A for a discussion of securities ratings. (See Types of Investments – Debt Obligations.)

Standby Commitments. Standby commitments are securities under which a purchaser, usually a bank or broker-dealer, agrees to purchase, for a fee, an amount of a Fund’s municipal obligations. The amount payable by a bank or broker-dealer to purchase securities subject to a standby commitment typically will be substantially the same as the value of the underlying municipal securities. A Fund may pay for standby commitments either separately in cash or by paying a higher price for portfolio securities that are acquired subject to such a commitment.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with standby commitments include: Counterparty Risk, Market Risk and Municipal Securities Risk.

Taxable Municipal Obligations. Interest or other investment return is subject to federal income tax for certain types of municipal obligations for a variety of reasons. These municipal obligations do not qualify for the federal income tax exemption because (a) they did not receive necessary authorization for tax-exempt treatment from state or local government authorities, (b) they exceed certain regulatory limitations on the cost of issuance for tax-exempt financing or (c) they finance public or private activities that do not qualify for the federal income tax exemption. These non-qualifying activities might include, for example, certain types of multi-family housing, certain professional and local sports facilities, refinancing of certain municipal debt, and borrowing to replenish a municipality’s underfunded pension plan.

See Appendix A for a discussion of securities ratings. (See Types of Investments – Debt Obligations.)

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with municipal securities include: Credit Risk, Inflation Risk, Interest Rate Risk, Market Risk and Municipal Securities Risk.

Participation Interests

Participation interests (also called pass-through certificates or securities) represent an interest in a pool of debt obligations, such as municipal bonds or notes that have been “packaged” by an intermediary, such as a bank or broker-dealer. Participation interests typically are issued by partnerships or trusts through which a Fund receives principal and interest payments that are passed through to the holder of the participation interest from the payments made on the underlying debt obligations. The purchaser of a participation interest receives an undivided interest in the underlying debt obligations. The issuers of the underlying debt obligations make interest and principal payments to the intermediary, as an initial purchaser, which are passed through to purchasers in the secondary market, such as a Fund. Mortgage-backed securities are a common type of participation interest. Participation interests may be structured as fixed-, variable- or floating-rate obligations or as zero-coupon, pay-in- kind and step-coupon securities and may be privately placed or publicly offered. See Types of Investments – Variable- and Floating-Rate Obligations, – Debt Obligations – Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and – Private Placement and Other Restricted Securities for more information.

Loan participations also are a type of participation interest. Loans, loan participations, and interests in securitized loan pools are interests in amounts owed by a corporate, governmental, or other borrower to a lender or consortium of lenders (typically banks, insurance companies, investment banks, government agencies, or international agencies).

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with loan participations include: Confidential Information Access Risk, Credit Risk and Interest Rate Risk.

Partnership Securities

The Fund may invest in securities issued by publicly traded partnerships or master limited partnerships or limited liability companies (together referred to as “PTPs/MLPs”). These entities are limited partnerships or limited liability companies that may be publicly traded on stock exchanges or markets such as the NYSE, the NYSE Alternext US LLC (formerly the American Stock Exchange) and NASDAQ. PTPs/MLPs often own businesses or properties relating to energy, natural resources or real estate, or may be involved in the film industry or research and development activities. Generally PTPs/MLPs are operated under the supervision of one or more managing partners or members. Limited partners, unit holders, or members (such as a fund that invests in a partnership) are not involved in the day-to-day management of the company. Limited partners, unit holders, or members are allocated income and capital gains associated with the partnership project in accordance with the terms of the partnership or limited liability company agreement.

Table of Contents

At times PTPs/MLPs may potentially offer relatively high yields compared to common stocks. Because PTPs/MLPs are generally treated as partnerships or similar limited liability “pass-through” entities for tax purposes, they do not ordinarily pay income taxes, but pass their earnings on to unit holders (except in the case of some publicly traded firms that may be taxed as corporations). For tax purposes, unit holders may initially be deemed to receive only a portion of the distributions attributed to them because certain other portions may be attributed to the repayment of initial investments and may thereby lower the cost basis of the units or shares owned by unit holders. As a result, unit holders may effectively defer taxation on the receipt of some distributions until they sell their units. These tax consequences may differ for different types of entities.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with partnership securities include: Interest Rate Risk, Issuer Risk, Liquidity Risk and Market Risk.

Preferred Stock

Preferred stock represents units of ownership of a corporation that frequently have dividends that are set at a specified rate. Preferred stock has preference over common stock in the payment of dividends and the liquidation of assets. Preferred stock shares some of the characteristics of both debt and equity. Preferred stock ordinarily does not carry voting rights. Most preferred stock is cumulative; if dividends are passed (i.e., not paid for any reason), they accumulate and must be paid before common stock dividends. Participating preferred stock entitles its holders to share in profits above and beyond the declared dividend, along with common shareholders, as distinguished from nonparticipating preferred stock, which is limited to the stipulated dividend. Convertible preferred stock is exchangeable for a given number of shares of common stock and thus tends to be more volatile than nonconvertible preferred stock, which generally behaves more like a fixed income bond. Preferred stock may be privately placed or publicly offered. The price of a preferred stock is generally determined by earnings, type of products or services, projected growth rates, experience of management, liquidity, and general market conditions of the markets on which the stock trades. See Types of Investments – Private Placement and Other Restricted Securities for more information.

Auction preferred stock (APS) is a type of adjustable-rate preferred stock with a dividend determined periodically in a Dutch auction process by corporate bidders. An APS is distinguished from standard preferred stock because its dividends change from time to time. Shares typically are bought and sold at face values generally ranging from $100,000 to $500,000 per share. Holders of APS may not be able to sell their shares if an auction fails, such as when there are more shares of APS for sale at an auction than there are purchase bids.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with preferred stock include: Convertible Securities Risk, Issuer Risk, Liquidity Risk and Market Risk.

Trust-Preferred Securities. Trust-preferred securities, also known as trust-issued securities, are securities that have characteristics of both debt and equity instruments and are typically treated by the Funds as debt investments.

Generally, trust-preferred securities are cumulative preferred stocks issued by a trust that is created by a financial institution, such as a bank holding company. The financial institution typically creates the trust with the objective of increasing its capital by issuing subordinated debt to the trust in return for cash proceeds that are reflected on the financial institutions balance sheet.

The primary asset owned by the trust is the subordinated debt issued to the trust by the financial institution. The financial institution makes periodic interest payments on the debt as discussed further below. The financial institution will subsequently own the trust’s common securities, which may typically represent a small percentage of the trust’s capital structure. The remainder of the trust’s capital structure typically consists of trust-preferred securities which are sold to investors. The trust uses the sales proceeds to purchase the subordinated debt issued by the financial institution. The financial institution uses the proceeds from the subordinated debt sale to increase its capital while the trust receives periodic interest payments from the financial institution for holding the subordinated debt.

The trust uses the interest received to make dividend payments to the holders of the trust-preferred securities. The dividends are generally paid on a quarterly basis and are often higher than other dividends potentially available on the financial institution’s common stocks. The interests of the holders of the trust-preferred securities are senior to those of common stockholders in the event that the financial institution is liquidated, although their interests are typically subordinated to those of other holders of other debt issued by the institution.

The primary benefit for the financial institution in using this particular structure is that the trust-preferred securities issued by the trust are treated by the financial institution as debt securities for tax purposes (as a consequence of which the expense of paying interest on the securities is tax deductible), but are treated as more desirable equity securities for purposes of the calculation of capital requirements.

In certain instances, the structure involves more than one financial institution and thus, more than one trust. In such a pooled offering, an additional separate trust may be created. This trust will issue securities to investors and use the proceeds to purchase the trust-preferred securities issued by other trust subsidiaries of the participating financial institutions. In such a structure, the trust-preferred securities held by the investors are backed by other trust-preferred securities issued by the trust subsidiaries.

Statement of Additional Information – [_________, 2022]

Table of Contents

If a financial institution is financially unsound and defaults on interest payments to the trust, the trust will not be able to make dividend payments to holders of the trust-preferred securities such as the Fund, as the trust typically has no business operations other than holding the subordinated debt issued by the financial institution(s) and issuing the trust-preferred securities and common stock backed by the subordinated debt.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with trust-preferred securities include: Credit Risk, Interest Rate Risk, Liquidity Risk and Prepayment and Extension Risk.

Private Placement and Other Restricted Securities

Private placement securities are securities that have been privately placed and are not registered under the 1933 Act. They are generally eligible for sale only to certain eligible investors. Private placements often may offer attractive opportunities for investment not otherwise available on the open market. Private placement and other “restricted” securities often cannot be sold to the public without registration under the 1933 Act or the availability of an exemption from registration (such as Rules 144 or 144A), or they are “not readily marketable” because they are subject to other legal or contractual delays in or restrictions on resale. Asset-backed securities, common stock, convertible securities, corporate debt securities, foreign securities, high-yield securities, money market instruments, mortgage-backed securities, municipal securities, participation interests, preferred stock and other types of equity and debt instruments may be privately placed or restricted securities.

Private placements typically may be sold only to qualified institutional buyers or, in the case of the initial sale of certain securities, such as those issued in collateralized debt obligations or collateralized loan obligations, to accredited investors (as defined in Rule 501(a) under the 1933 Act), or in a privately negotiated transaction or to a limited number of qualified purchasers, or in limited quantities after they have been held for a specified period of time and other conditions are met pursuant to an exemption from registration.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with private placement and other restricted securities include: Issuer Risk, Liquidity Risk, Market Risk and Confidential Information Access Risk.

Real Estate Investment Trusts

Real estate investment trusts (REITs) are pooled investment vehicles that manage a portfolio of real estate or real estate related loans to earn profits for their shareholders. 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, such as shopping centers, nursing homes, office buildings, apartment complexes, and hotels, and derive income primarily from the collection of rents. Equity REITs can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs invest the majority of their assets in real estate mortgages and derive income from the collection of interest payments. REITs can be subject to extreme volatility due to fluctuations in the demand for real estate, changes in interest rates, and adverse economic conditions.

Partnership units of real estate and other types of companies sometimes are organized as master limited partnerships in which ownership interests are publicly traded.

Similar to regulated investment companies, REITs are not taxed on income distributed to shareholders provided they comply with certain requirements under the Code. A Fund will indirectly bear its proportionate share of any expenses paid by a REIT in which it invests. REITs often do not provide complete tax information until after the calendar year-end. Consequently, because of the delay, it may be necessary for a Fund investing in REITs to request permission to extend the deadline for issuance of Forms 1099-DIV beyond January 31. In the alternative, amended Forms 1099-DIV may be sent.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with REITs include: Interest Rate Risk, Issuer Risk, Market Risk and Real Estate-Related Investment Risk.

Repurchase Agreements

Repurchase agreements are agreements under which a Fund acquires a security for a relatively short period of time (usually within seven days) subject to the obligation of a seller to repurchase and a Fund to resell such security at a fixed time and price (representing the Fund’s cost plus interest). The repurchase agreement specifies the yield during the purchaser’s holding period. Repurchase agreements also may be viewed as loans made by a Fund that are collateralized by the securities subject to repurchase, which may consist of a variety of security types. A Fund typically will enter into repurchase agreements only with commercial banks, registered broker-dealers and the Fixed Income Clearing Corporation. Such transactions are monitored to ensure that the value of the underlying securities will be at least equal at all times to the total amount of the repurchase obligation, including any accrued interest.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with repurchase agreements include: Counterparty Risk, Credit Risk, Issuer Risk, Market Risk and Repurchase Agreements Risk.

Reverse Repurchase Agreements

Reverse repurchase agreements are agreements under which a Fund temporarily transfers possession of a portfolio instrument to another party, such as a bank or broker-dealer, in return for cash. At the same time, the Fund agrees to repurchase the instrument at an agreed-upon time (normally within 7 days) and price which reflects an interest payment. A Fund generally retains the right to interest and principal payments on the security. Reverse repurchase agreements also may be viewed as borrowings made by a Fund.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with reverse repurchase agreements include: Credit Risk, Interest Rate Risk, Issuer Risk, Leverage Risk, Market Risk and Reverse Repurchase Agreements Risk.

Short Sales

A Fund may sometimes sell securities short when it owns an equal amount of the securities sold short. This is a technique known as selling short “against the box.” If a Fund makes a short sale “against the box,” it would not immediately deliver the securities sold and would not receive the proceeds from the sale. The seller is said to have a short position in the securities sold until it delivers the securities sold, at which time it receives the proceeds of the sale. To secure its obligation to deliver securities sold short, a Fund will deposit in escrow in a separate account with the custodian an equal amount of the securities sold short or securities convertible into or exchangeable for such securities. A Fund can close out its short position by purchasing and delivering an equal amount of the securities sold short, rather than by delivering securities already held by a Fund, because a Fund might want to continue to receive interest and dividend payments on securities in its portfolio that are convertible into the securities sold short.

Short sales “against the box” entail many of the same risks and considerations described below regarding short sales not “against the box.” However, when a Fund sells short “against the box” it typically limits the amount of its effective leverage. A Fund’s decision to make a short sale “against the box” may be a technique to hedge against market risks when a Fund’s portfolio manager believes that the price of a security may decline, causing a decline in the value of a security owned by a Fund or a security convertible into or exchangeable for such security. In such case, any future losses in a Fund’s long position would be reduced by a gain in the short position. The extent to which such gains or losses in the long position are reduced will depend upon the amount of securities sold short relative to the amount of the securities a Fund owns, either directly or indirectly, and, in the case where a Fund owns convertible securities, changes in the investment values or conversion premiums of such securities. Short sales may have adverse tax consequences to a Fund and its shareholders.

Subject to its fundamental and non-fundamental investment policies, a Fund may engage in short sales that are not “against the box,” which are sales by a Fund of securities, contracts or instruments that it does not own in hopes of purchasing the same security, contract or instrument at a later date at a lower price. The technique is also used to protect a profit in a long-term position in a security, commodity futures contract or other instrument. To make delivery to the buyer, a Fund must borrow or purchase the security. If borrowed, a Fund is then obligated to replace the security borrowed from the third party, so a Fund must purchase the security at the market price at a later time. If the price of the security has increased during this time, then a Fund will incur a loss equal to the increase in price of the security from the time of the short sale plus any premiums and interest paid to the third party. (Until the security is replaced, a Fund is required to pay to the lender amounts equal to any dividends or interest which accrue during the period of the loan. To borrow the security, a Fund also may be required to pay a premium, which would increase the cost of the security sold. The proceeds of the short sale will be retained by the broker, to the extent necessary to meet the margin requirements, until the short position is closed out.) Short sales of forward commitments and derivatives do not involve borrowing a security. These types of short sales may include futures, options, contracts for differences, forward contracts on financial instruments and options such as contracts, credit-linked instruments, and swap contracts.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with short sales include: Leverage Risk, Market Risk and Short Positions Risk.

Sovereign Debt

Sovereign debt obligations are issued or guaranteed by foreign governments or their agencies. It may be in the form of conventional securities or other types of debt instruments such as loans or loan participations. A sovereign debtor’s willingness or ability to repay principal and pay interest in a timely manner may be affected by a variety of factors, including its cash flow situation, the extent of its reserves, the availability of sufficient foreign 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 international lenders, and the political constraints to which a sovereign debtor may be subject. (See also Types of Investments – Foreign Securities.) In addition, there may be no legal recourse against a sovereign debtor in the event of a default.

Sovereign debt includes Brady Bonds, which are securities issued under the framework of the Brady Plan, an initiative announced by former U.S. Treasury Secretary Nicholas F. Brady in 1989 as a mechanism for debtor nations to restructure their outstanding external commercial bank indebtedness.

U.S. Government and Related Obligations

U.S. Government obligations include U.S. Treasury obligations and securities issued or guaranteed by various agencies of the U.S. Government or by various agencies or instrumentalities established or sponsored by the U.S. Government. U.S. Treasury obligations and securities issued or guaranteed by various agencies or instrumentalities of the U.S. Government differ in their interest rates, maturities and time of issuance, as well as with respect to whether they are guaranteed by the U.S. Government. U.S. Government and related obligations may be structured as fixed-, variable- or floating-rate obligations. See Types of Investments – Variable- and Floating-Rate Obligations for more information.

Investing in U.S. Government and related obligations is subject to certain risks. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies and U.S. Government-sponsored instrumentalities may or may not be backed by the full faith and credit of the U.S. Government. These securities may be supported by the ability to borrow from the U.S. Treasury or only by the credit of the issuing agency or instrumentality and, as a result, may be subject to greater credit risk than securities issued or guaranteed by the U.S. Treasury. Obligations of U.S. Government agencies, authorities, instrumentalities and sponsored enterprises historically have involved limited risk of loss of principal if held to maturity. However, no assurance can be given that the U.S. Government would provide financial support to any of these entities if it is not obligated to do so by law.

Government-sponsored entities issuing securities include privately owned, publicly chartered entities created to reduce borrowing costs for certain sectors of the economy, such as farmers, homeowners, and students. They include the Federal Farm Credit Bank System, Farm Credit Financial Assistance Corporation, Fannie Mae, Freddie Mac, and Student Loan Marketing Association (SLMA). Government-sponsored entities may issue discount notes (with maturities ranging from overnight to 360 days) and bonds. On September 7, 2008, the Federal Housing Finance Agency (FHFA), an agency of the U.S. Government, placed Fannie Mae and Freddie Mac into conservatorship, a statutory process with the objective of returning the entities to normal business operations. FHFA will act as the conservator to operate the enterprises until they are stabilized.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with U.S. Government and related obligations include: Credit Risk, Inflation Risk, Interest Rate Risk, Prepayment and Extension Risk, Reinvestment Risk and U.S. Government Obligations Risk.

Variable- and Floating-Rate Obligations

Variable- and floating-rate obligations are debt instruments that provide for periodic adjustments in the interest rate and, under certain circumstances, varying principal amounts. Unlike a fixed interest rate, a variable, or floating, rate is one that rises and declines based on the movement of an underlying index of interest rates and may pay interest at rates that are adjusted periodically according to a specified formula. Variable- or floating-rate securities frequently include a demand feature enabling the holder to sell the securities to the issuer at par. In many cases, the demand feature can be exercised at any time. Some securities that do not have variable or floating interest rates may be accompanied by puts producing similar results and price characteristics. Variable-rate demand notes include master demand notes that are obligations that permit the investor to invest fluctuating amounts, which may change daily without penalty, pursuant to direct arrangements between the investor (as lender), and the borrower. The interest rates on these notes fluctuate. The issuer of such obligations normally has a corresponding right, after a given period, to prepay in its discretion the outstanding principal amount of the obligations plus accrued interest upon a specified number of days’ notice to the holders of such obligations. Because these obligations are direct lending arrangements between the lender and borrower, it is not contemplated that such instruments generally will be traded. There generally is not an established secondary market for these obligations. Accordingly, where these obligations are not secured by letters of credit or other credit support arrangements, the lender’s right to redeem is dependent on the ability of the borrower to pay principal and interest on demand. Such obligations frequently are not rated by credit rating agencies and may involve heightened risk of default by the issuer.
