Introduction—ALPS ETF Trust

ALPS ETF Trust (the “Trust”) is an investment company consisting of multiple separate exchange traded funds. This Prospectus relates to the RiverFront Dynamic US Dividend Advantage ETF and the RiverFront Dynamic US Flex-Cap ETF (each a “Fund” and together, the “Funds”). ALPS Advisors, Inc. (“ALPS Advisors” or the “Adviser”) is the Adviser to the Funds. RiverFront Investment Group, LLC (“RiverFront” or the “Sub-Adviser”) is the Sub-Adviser to the Funds.

Each Fund’s Shares are listed on the NYSE Arca, Inc. (the “NYSE Arca”). Each Fund’s Shares trade at market prices that may differ from the net asset value (“NAV”) of the Shares. Unlike conventional mutual funds, each Fund issues and redeems Shares on a continuous basis, at NAV, only in large specified blocks, each of which is called a “Creation Unit.” Creation Units are issued and redeemed principally in kind for portfolio securities, and each Fund reserves the right to effect redemptions wholly or partially in cash. Except when aggregated in Creation Units, Shares are not redeemable by the Funds.

Tax-Advantaged Product Structure 

Unlike interests in many conventional mutual funds, the Shares are traded throughout the day on a national securities exchange, whereas mutual fund interests are typically only bought and sold at closing NAVs. The Shares have been designed to be tradable in the secondary market on a national securities exchange on an intra-day basis, and to be created and redeemed principally in-kind in Creation Units at each day’s next calculated NAV. These arrangements are designed to protect ongoing shareholders from adverse effects on the Fund’s portfolio that could arise from frequent cash creation and redemption transactions. In a conventional mutual fund, redemptions can have an adverse tax impact on taxable shareholders because of the mutual fund’s need to sell portfolio securities to obtain cash to meet fund redemptions. These sales may generate taxable gains for the shareholders of the mutual fund, whereas the in-kind redemption mechanism utilized by most exchange-traded funds, including the Fund, generally will not lead to a tax event for the Fund or its ongoing shareholders.

Additional Information About the Funds’ Principal Investment Risks

Investors should consider the following additional information about the Fund’s principal investment risks.

Financial Services Sector Risk. The financial services sector is subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets in the aftermath of the 2007-2008 financial crisis generally caused the financial sector to experience an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector in late 2008 resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses.

Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. A principal risk of investing in each Fund is market risk, which is the risk that the value of the securities held by the Fund will fall due to general market, economic, political and social conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by a Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. Securities in a Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of a Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics.

For example, the outbreak of COVID-19, a novel coronavirus disease, has negatively affected economies, markets and individual companies throughout the world, including those in which the Fund invests. The effects of this pandemic to

public health and business and market conditions, including exchange trading suspensions and closures may continue to have a significant negative impact on the performance of the Fund’s investments, increase the Fund’s volatility, negatively impact the Fund’s arbitrage and pricing mechanisms, exacerbate pre-existing political, social and economic risks to the Fund, and negatively impact broad segments of businesses and populations. The Fund’s operations may be interrupted as a result, which may contribute to the negative impact on investment performance. In addition, governments, their regulatory agencies, or self-regulatory organizations may take actions in response to the pandemic that affect the instruments in which the Fund invests, or the issuers of such instruments, in ways that could have a significant negative impact on the Fund’s investment performance. The full impact of the COVID-19 pandemic, or other future epidemics or pandemics, is currently unknown.

In addition, common stock of an issuer in a Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. While broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Investment Risk. An investment in a Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.

Issuer-Specific Risk. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

Quantitative Methodology Risk. The Sub-Adviser uses certain quantitative methodologies to help assess the criteria of issuers to be included in a Fund’s portfolio, including information that may be based on assumptions and estimates. Neither the Funds, the Adviser nor the Sub-Adviser can offer assurances that the quantitative methodology will provide an accurate assessment of included issuers.

Small- and Mid-Capitalization Company Risk. Investments in securities of small- and mid-capitalization companies are subject to the risks of common stocks. Investments in smaller and mid-sized companies may involve greater risks because these companies generally have a limited track record. A small capitalization company is defined as a company with a market capitalization between $300 million and $2 billion. A medium capitalization company is defined as a company with a market capitalization between $2 billion and $10 billion. Smaller and mid-sized companies often have narrower markets, less liquidity, more limited managerial and financial resources and a less diversified product offering than larger, more established companies. As a result, their performance can be more volatile, which may increase the volatility of a Fund’s portfolio.

Management Risk. Each Fund is subject to management risk because it is an actively managed portfolio. In managing a Fund’s portfolio securities, the Sub-Adviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results.

Real Estate Investment Risk. Investing in real estate is subject to such risks as decreases in real estate values, overbuilding, increased competition and other risks related to local or general economic conditions, increases in operating costs and property taxes, changes in zoning laws, casualty or condemnation losses, possible environmental liabilities, regulatory limitations on rent, possible lack of availability of mortgage financing, market saturation, fluctuations in rental income and the value of underlying properties and extended vacancies of properties. Certain real estate securities have a relatively small market capitalization, which may tend to increase the volatility of the market price of these securities. Real estate securities have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants. The real estate sector is particularly sensitive to economic downturns and changes to interest rates.

REIT Investment Risk. In addition to risks related to investments in real estate generally, investing in REITs involves certain other risks related to their structure and focus, which include, but are not limited to, dependency upon management skills, limited diversification, the risks of locating and managing financing for projects, heavy cash flow dependency, possible default by borrowers, the costs and potential losses of self-liquidation of one or more holdings, the risk of a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages, changes in neighborhood values and appeal to purchases, the possibility of failing to maintain exemptions from registration under the 1940 Act and, in many cases, relatively small market capitalization, which may result in less market liquidity and greater price volatility. REITs are also subject to the risk that the real estate market may experience an economic downturn generally, which may have a material effect on the real estate in which the REITs invest and their underlying portfolio securities. In addition, like mutual funds and ETFs, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs.

REITs are also subject to unique federal tax requirements. REITs that fail to comply with federal tax requirements affecting REITs may be subject to federal income taxation, which may affect the value of such REIT and the characterization of such REIT’s

distributions, and REITs that fail to comply with the federal tax requirement that REITs distribute substantially all of their net income to their respective shareholders may result in such REITs having insufficient capital for future expenditures. The failure of one or more companies to qualify as REITs could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such companies.

Individuals and certain other noncorporate entities are generally eligible for a 20% deduction with respect to taxable ordinary dividends from REITs. Internal Revenue Service regulations allow a regulated investment company such as a Fund to pass through to shareholders such taxable ordinary dividends from REITs. Accordingly, individual and certain other non-corporate shareholders of a regulated investment company that have received such taxable ordinary dividends from REITs may be able to take advantage of this 20% deduction with respect to any such amounts passed through through 2025.

REITs often do not provide complete tax information until after the calendar year-end. Consequently, because of the delay, it may be necessary for the Fund to request permission to extend the deadline for issuance of Forms 1099-DIV. Dividends received by the Fund from REITs generally will not constitute qualified dividend income.

Dividend-Paying Stock Risk. RiverFront Dynamic US Dividend Advantage ETF’s emphasis on dividend-paying stocks involves the risk that such stocks may fall out of favor with investors and underperform the market. Also, a company may reduce or eliminate its dividend. An issuer of a security may also be unable or unwilling to make dividend payments when due and the related risk that the value of a security may decline because of concerns about the issuer’s ability to make such payments.

Growth Investment Risk. Growth stock prices reflect projections of future earnings or revenues, and can therefore fall dramatically if the company fails to meet those projections. Growth stocks may be more expensive relative to their current earnings or assets compared to value or other stocks, and if earnings growth expectations moderate, their valuations may return to more typical levels, causing their stock prices to fall. Prices of these companies’ securities may be more volatile than other securities, particularly over the short term, because they are more sensitive to investor perceptions of the issuer’s growth of earnings potential. Disciplined adherence to a growth investment style during a period in which that style is out of favor can result in significant underperformance relative to overall market indices and other managed investment vehicles that pursue, for example, value style investments and/or flexible investment styles.

Momentum Investing Risk. The Funds may employ in part a “momentum” style methodology that emphasizes selecting securities that have had higher recent price performance compared to other securities. The Funds may be subject to more risk because securities in which a Fund invests based on momentum may be more volatile than a broad cross-section of securities or the returns on securities that have previously exhibited price momentum are less than returns on other styles of investing or the overall stock market.

Value Investing Risk. Value securities may present risks in addition to the general risks associated with investing in securities. These securities are selected on the basis of an issuer’s business and economic fundamentals or a security’s current credit profile, relative to current market practice. Disciplined adherence to a “value” investment style during a period in which that style is “out of favor” can result in significant underperformance relative to overall market indices and other managed investment vehicles that pursue growth style investments and/or flexible style mandates.

Asset Allocation Program Risk. The Sub-Adviser specializes in managing asset allocation portfolios, which invest in various investment vehicles, including the Funds and other ETFs, to obtain targeted amounts of exposure to different asset classes. The Funds were developed to serve as, and will serve as, investment vehicles for such asset allocation portfolios. As the manager of the Funds and the portfolios, the Sub-Adviser is likely to encounter conflicts of interest. For example, the Sub-Adviser may need to reduce its asset allocation portfolios’ exposure to an asset class to which the portfolios obtain exposure by investing in a Fund. Under such circumstances, the Sub-Adviser would liquidate some or all of the portfolios’ investments in the Fund, which could adversely affect the Fund.

Fluctuation of Net Asset Value. The NAV of a Fund’s Shares will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of the Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for the Shares on the NYSE Arca. The Sub-Adviser cannot predict whether the Shares will trade below, at or above their NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for the Shares will be closely related to, but not identical to, the same forces influencing the prices of the Fund’s holdings trading individually or in the aggregate at any point in time. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the NYSE Arca and may, therefore, have a material effect on the market price of the Fund’s Shares. In addition, unlike conventional ETFs, the Funds are not index funds. The Funds are actively managed and do not seek to replicate the performance of a specified index. Index based ETFs have generally traded at prices which closely correspond to NAV per Share. Actively managed ETFs have a more limited trading history and, therefore, there can be no assurance as to whether and/or the extent to which the Shares will trade at premiums or discounts to NAV.

Secondary Investment Strategies

As a non-principal investment strategy, each Fund may invest part of its remaining assets in preferred stocks, convertible stocks, depositary receipts, business development companies (“BDCs”), master limited partnerships (“MLPs”), money market instruments, including repurchase agreements or other funds which invest exclusively in money market instruments, and in swaps, options and futures and forward contracts. Each Fund may also invest in money market instruments, cash, or other short-term fixed income instruments as part of a temporary defensive strategy to protect against temporary market declines.

Each Fund may lend its portfolio securities to brokers, dealers and other financial institutions desiring to borrow securities to complete transactions and for other purposes. In connection with such loans, each Fund receives liquid collateral equal to at least 102% of the value of the portfolio securities being lent, and will be maintained in an amount equal to at least 100% of the value of the portfolio securities being lent.

The investment objective and policies described herein constitute non fundamental policies that may be changed by the Board of Trustees of the Trust without shareholder approval. Certain other fundamental policies of each Fund are set forth in the Statement of Additional Information under “Investment Restrictions.”

Additional Risk Considerations

In addition to the risks described previously, there are certain other risks related to investing in each Fund.

Borrowing and Leverage Risks. If a Fund borrows money, it must pay interest and other fees, which may reduce the Fund’s returns. As prescribed by the 1940 Act, each Fund will be required to maintain specified asset coverage of at least 300% with respect to any bank borrowing immediately following such borrowing. A Fund may be required to dispose of assets on unfavorable terms if market fluctuations or other factors reduce the Fund’s asset coverage to less than the prescribed amount.

Cash Transactions Risk. The Funds may, under certain circumstances, effect a portion of creations and redemptions for cash, rather than in-kind securities. As a result, an investment in the Funds may be less tax-efficient than an investment in an ETF that effects its creations and redemptions for in-kind securities. ETFs are able to make in-kind redemptions and avoid being taxed on gains on the distributed portfolio securities at the fund level. Because the Funds may effect a portion of redemptions for cash, they may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. Any recognized gain on these sales by the Funds will generally cause the Funds to recognize gain they might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if they were to distribute portfolio securities in-kind. The Funds generally intend 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 them. 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 Funds sold and redeemed their shares in-kind, will be passed on to purchasers and redeemers of Creation Units in the form of creation and redemption transaction fees. In addition, these factors may result in wider spreads between the bid and the offered prices of the Funds’ shares than for ETFs that distribute portfolio securities in-kind.

Convertible Securities Risk. A Fund’s investments in convertible securities subject the Fund to the risks associated with both fixed income securities and common stocks. To the extent that a convertible security’s investment value is greater than its conversion value, its price will be likely to increase when interest rates fall and decrease when interest rates rise, as with a fixed income security. If the conversion value exceeds the investment value, the price of the convertible security will tend to fluctuate directly with the price of the underlying equity security.

Derivatives Risk. Derivatives are financial instruments, such as futures, swaps and options, whose values are based on the value of one or more indicators, such as a security, asset, currency, interest rate, or index. Derivatives involve risks different from, and possibly greater than, the risks associated with investing directly in securities and other more traditional investments. For example, derivatives involve the risk of mispricing or improper valuation and the risk that changes in the value of a derivative may not correlate perfectly with the underlying indicator. Derivative transactions can create investment leverage, may be highly volatile and a Fund could lose more than the amount it invests. Many derivative transactions are entered into “over-the-counter” (not on an exchange or contract market); as a result, the value of such a derivative transaction will depend on the ability and the willingness of a Fund’s counterparty to perform its obligations under the transaction. If a counterparty were to default on its obligations, the Fund’s contractual remedies against such counterparty may be subject to bankruptcy and insolvency laws, which could affect the Fund’s rights as a creditor (e.g., the Fund may not receive the net amount of payments that it is contractually entitled to receive). A liquid secondary market may not always exist for a Fund’s derivative positions at any time.

Illiquid Securities Risk. Illiquid securities may be difficult to dispose of at the price at which a Fund has valued the securities and at the times when the Fund believes it is desirable to do so. The market price of illiquid securities generally is more volatile than that of more liquid securities, which may adversely affect the price that a Fund recovers upon the sale of such securities. Illiquid securities are also more difficult to value, especially in challenging markets. The Sub-Adviser’s judgment may play a greater role in the valuation process. Investment of a Fund’s assets in illiquid securities may restrict the Fund’s ability to take advantage of market opportunities. The risks associated with illiquid securities may be particularly acute in situations in which a Fund’s operations require cash and could result in the Fund incurring losses on the sale of illiquid or restricted securities.

Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Funds’ assets can decline as can the value of the Funds’

distributions. Certain securities in which the Funds invest may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of units of MLPs have more limited control rights and limited rights to vote on matters affecting the MLP as compared to holders of stock of a corporation. For example, MLP unit holders may not elect the general partner or the directors of the general partner and the MLP unit holders have limited ability to remove an MLP’s general partner. MLPs are controlled by their general partners, which generally have conflicts of interest and limited fiduciary duties to the MLP, which may permit the general partner to favor its own interests over the MLPs.

Individuals and certain other noncorporate entities are generally eligible for a 20% deduction with respect to taxable income from MLPs. Currently, there is not a regulatory mechanism for regulated investment companies such as the Fund to pass through the 20% deduction to shareholders. As a result, in comparison, investors investing directly in MLPs would generally be eligible for the 20% deduction for such taxable income from these investments while investors investing in MLPs held indirectly if any through the Funds would not be eligible for the 20% deduction for their share of such taxable income.

BDC Risk. Investments in BDCs may be subject to a high degree of risk. BDCs may carry risks similar to those of a private equity or venture capital fund. BDC securities are not redeemable at the option of the shareholder and they may trade in the market at a discount to their NAV. BDCs usually trade at a discount to their NAV because they invest in unlisted securities and have limited access to capital markets. BDCs are subject to management and other expenses, which will be indirectly paid by the Fund.

Risk of Investment in Other Investment Companies. Subject to the limitations set forth in the 1940 Act, or as otherwise permitted by the SEC, each Fund may acquire shares in other ETFs, closed-end funds and/or business development companies. The market value of the shares of other investment companies may differ from their NAVs. In addition, the shares of closed-end investment companies frequently trade at a discount to their NAV. As an investor in investment companies, each Fund would bear its ratable share of that entity’s expenses, including its investment advisory and administration fees, while continuing to pay its own advisory and administration fees and other expenses. As a result, shareholders will be absorbing duplicate levels of fees with respect to investments in other investment companies.

The securities of certain other closed-end funds in which each Fund may invest may be leveraged. As a result, each Fund may be indirectly exposed to leverage through an investment in such securities. An investment in securities of other investment companies that use leverage may expose each Fund to higher volatility in the market value of such securities and the possibility that each Funds’ long-term returns on such securities (and, indirectly, the long-term returns of the Shares) will be diminished.

Trading Issues. Trading in Shares on the NYSE Arca may be halted due to market conditions or for reasons that, in the view of the NYSE Arca, make trading in Shares inadvisable. In addition, trading in Shares on the NYSE Arca is subject to trading halts caused by extraordinary market volatility pursuant to the NYSE Arca “Circuit breaker” rules. If a trading halt or unanticipated early closing of NYSE Arca occurs, a shareholder may be unable to purchase or sell Shares of a Fund. There can be no assurance that the requirements of the NYSE Arca necessary to maintain the listing of a Fund will continue to be met or will remain unchanged.

While the creation/redemption feature is designed to help the Shares trade close to each Fund’s NAV, market prices are not expected to correlate exactly to a Fund’s NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, adverse developments impacting market makers, authorized participants or other market participants, high market volatility or lack of an active trading market for the Shares (including through a trading halt) may result in market prices for Shares of a Fund that differ significantly from its NAV or to the intraday value of the Fund’s holdings. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses.

When you buy or sell Shares of a Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers. In addition, the market price of Shares, like the price of any exchange-traded security, includes a “bid/ask spread” charged by the market makers or other participants that trade the particular security. The spread of a Fund’s Shares varies over time based on the Fund’s trading volume and market liquidity and may increase if the Fund’s trading volume, the spread of the Fund’s underlying securities, or market liquidity decrease. In times of severe market disruption, including when trading of a Fund’s holdings may be halted, the bid/ask spread may increase significantly. This means that Shares may trade at a discount to a Fund’s NAV, and the discount is likely to be greatest during significant market volatility. During such periods, you may be unable to sell your Shares or may incur significant losses if you sell your Shares. There are various methods by which investors can purchase and sell shares of the Fund and various orders that may be placed. Investors should consult their financial intermediary before purchasing or selling shares of the Fund.

Shareholder Risk. Certain shareholders, including other funds advised by the Adviser, may from time to time own a substantial amount of a Fund’s Shares. In addition, a third party investor, the Adviser or an affiliate of the Adviser, an authorized participant, a market maker or another entity may invest in a Fund and hold its investment for a limited period of time. There can be no assurance that any large shareholder would not redeem its investment. Redemptions by shareholders could have a negative impact on a Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on a Fund’s listing exchange and may, therefore, have a material effect on the market price of the Shares.

Authorized Participant Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with a Fund. A Fund has a limited number of intermediaries that act as authorized participants, and none of these authorized participants are or will be obligated to engage in creation or redemption transactions. To the extent that these intermediaries exit the business or are unable to or choose not to proceed with creation and/or redemption orders (including in situations where authorized participants have limited or diminished access to capital required to post collateral), with respect to a Fund and no other authorized participant is able to step forward to create or redeem, Shares may trade at a discount to NAV and possibly face trading halts and/or delisting (that is, investors would no longer be able to trade shares in the secondary market). The authorized participant concentration risk may be heightened in scenarios where authorized participants have limited or diminished access to the capital required to post collateral.

No Guarantee of Active Trading Market Risk. While Shares are listed on NYSE Arca, there can be no assurance that active trading markets for the Shares will be maintained by market makers or authorized participants. Decisions by market makers or authorized participants to reduce their role or “step away” from these activities in times of market stress may inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying value of a Fund’s holdings and the Fund’s NAV. Such reduced effectiveness could result in a Fund’s Shares trading at a discount to its NAV and also in greater than normal intraday bid/ask spreads for the Fund’s Shares. Additionally, in stressed market conditions, the market for a Fund’s Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings. This adverse effect on liquidity for a Fund’s Shares in turn could lead to differences between the market price of the Fund’s Shares and the Fund’s NAV per Share.

Securities Lending. Although each Fund will receive collateral in connection with all loans of its securities holdings, a Fund would be exposed to a risk of loss should a borrower default on its obligation to return the borrowed securities (e.g., the loaned securities may have appreciated beyond the value of the collateral held by a Fund). In the event of a bankruptcy of the borrower, a Fund could experience losses or delays in recovering the loaned securities. Loans of securities also involve a risk that the borrower may fail to return the securities or deliver the proper amount of collateral, which may result in a loss to a Fund. In addition, each Fund will bear the risk of loss of any cash collateral that it invests.

Operational Risk. The Funds are exposed to operational risk arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Funds’ service providers, counterparties or other third-parties, failed or inadequate processes and technology or system failures. The Funds seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate for those risks that they are intended to address.

These risks are described further in the Statement of Additional Information.

Investment Advisory Services

Investment Adviser

ALPS Advisors, Inc. (“ALPS Advisors” or the “Adviser”) acts as the Fund’s investment adviser pursuant to an advisory agreement with the Trust on behalf of the Fund (the “Advisory Agreement”). The Adviser, located at 1290 Broadway, Suite 1000, Denver, Colorado 80203, is registered with the Securities and Exchange Commission as an investment adviser. As of December 31, 2021, the Adviser provided supervisory and management services on approximately $17.3 billion in assets through closed-end funds, mutual funds and exchange-traded funds. Pursuant to the Advisory Agreement, the Adviser manages the investment and reinvestment of the Fund’s assets and administers the affairs of the Fund subject to the supervision of the Board of Trustees.

Pursuant to the Advisory Agreement, each Fund pays the Adviser an annual management fee for the services and facilities it provides as a percentage of the relevant Fund’s average daily net assets as set out below:

With respect to each Fund, the unitary advisory fee as a percentage of net assets is subject to the following breakpoints: (i) 0.52% for average net assets up to $600 million, (ii) 0.49% for average net assets equal to or greater than $600 million.

Sub-Adviser

RiverFront Investment Group, LLC acts as each Fund’s Sub Adviser pursuant to a sub advisory agreement with the Trust and ALPS Advisors (the “Sub Advisory Agreement”). RiverFront is located at 1214 East Cary Street, Richmond, VA 23219.

RiverFront is majority-owned by its employees but is affiliated with Baird Financial Corporation (“Baird”) as a result of Baird’s minority equity interest and representation on RiverFront’s board of directors. RiverFront is an investment adviser registered with the Securities Exchange Commission under the Investment Advisers Act of 1940. The company manages a variety of portfolios utilizing stocks, bonds, and ETFs. RiverFront also serves as sub-advisor to a series of mutual funds and ETFs. As of December 31, 2021, RiverFront had approximately $9.8 billion in assets under advisement (discretionary and non-discretionary assets).

Pursuant to the Sub-Advisory Agreement with the Trust on behalf of each Fund, and ALPS Advisors, RiverFront furnishes an investment program for each Fund and manages the investment operations and composition of each Fund.

The Fund enters into contractual arrangements with various parties, including, among others, the Fund’s investment adviser, who provide services to the Fund. Shareholders are not parties to, or intended (or “third-party”) beneficiaries of those contractual arrangements.

This Prospectus and the Statement of Additional Information provide information concerning the Fund that you should consider in determining whether to purchase shares of the Fund. The Fund may make changes to this information from time to time. Neither this Prospectus nor the Statement of Additional Information is intended to give rise to any contract rights or other rights in any shareholder, other than any rights conferred by federal or state securities laws.

Approval of Advisory Agreement and Sub-Advisory Agreement

A discussion regarding the basis for the Board of Trustees’ approval of the Advisory Agreement and Sub-Advisory Agreement is available in the Funds’ annual report to shareholders for the period ended November 30, 2021, and will be available in the Funds’ annual report to shareholders for the period ending November 30, 2022.

Manager of Managers Structure

The Trust and the Adviser operate under a manager-of-managers structure under an order issued by the SEC (the “Order”). The Order permits the Adviser to enter into, terminate or materially amend sub-advisory agreements without shareholder approval. This means the Adviser has the ultimate responsibility, subject to oversight by the Board of Trustees, to oversee the Sub-Adviser and recommend the hiring, termination and replacement of a sub-adviser.

The Trust will furnish to shareholders of the Fund all information about a new sub-adviser or sub-advisory agreement that would be included in an information statement within 90 days after the addition of the new sub-adviser or the implementation of any material change in the sub-advisory agreement. The Order enables the Funds to operate with greater efficiency and without incurring the expense and delays associated with obtaining further shareholder approval of sub-advisory agreements. The Order does not permit investment advisory fees paid by a Fund to be increased or change the Adviser’s obligation under the Advisory Agreement, including the Adviser’s responsibility to monitor and oversee sub-advisory services furnished to a Fund, without further shareholder approval. Pursuant to the Order, the Adviser is not required to disclose its contractual fee arrangement with any sub-adviser.

The Adviser will not enter into a sub-advisory agreement with any sub-adviser that is an affiliated person, as defined in Section 2(a)(3) of the Investment Company Act of 1940, as amended, (the “1940 Act”), of the Trust or the Adviser other than by reason of serving as a sub-adviser to one or more funds without such agreement, including the compensation to be paid thereunder, being approved by the shareholders of the Fund. The Adviser compensates each sub-adviser out of its management fee.

Portfolio Management

The Sub-Adviser furnishes an investment program for each Fund, manages the investment portfolio of each Fund and directs the purchase and sale of each Fund’s investment securities.

The portfolio managers are primarily responsible for the day-to-day management of each Fund. The individuals listed below are members of the investment management team at RiverFront that manages each Fund’s investments and reinvestment of assets. As described below, each member has a different role on the team, and decisions as to the purchases and sales of securities are considered by the relevant members of the team as indicated below.

Mr. Konstantinos received his CFA designation in 2013 and holds FINRA Series 7 and 66 licenses.

The Statement of Additional Information provides additional information about the portfolio managers’ compensation structure, other accounts managed by the portfolio managers and the portfolio managers’ ownership of securities of each Fund.

Purchase and Redemption of Shares

General

The Shares are issued or redeemed by each Fund at NAV per Share only in Creation Units. See “How to Buy and Sell Shares.”

Most investors buy and sell Shares of each Fund in secondary market transactions through brokers. Shares of each Fund are listed for trading in the secondary market on the NYSE Arca. Shares can be bought and sold throughout the trading day like other publicly traded shares. There is no minimum investment. Although Shares are generally purchased and sold in “round lots” of 100 Shares, brokerage firms typically permit investors to purchase or sell Shares in smaller “odd lots,” at no per share price differential. When buying or selling Shares through a broker, you will incur customary brokerage commissions and charges, and you may pay some or all of the spread between the bid and the offered price in the secondary market on each leg of a round trip (purchase and sale) transaction. Each Fund trades on the NYSE Arca at prices that may differ to varying degrees from the daily NAV of the Shares. Given that each Fund’s Shares can be issued and redeemed in Creation Units, large discounts and premiums to NAV should not be sustained for long. The Funds trade under the NYSE Arca ticker symbols set forth below:

Share prices are reported in dollars and cents per Share.

Investors may acquire Shares directly from each Fund, and shareholders may tender their Shares for redemption directly to the Fund, only in Creation Units, as discussed in the “How to Buy and Sell Shares” section below.

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 record owner of all outstanding Shares of a Fund and is recognized as the owner of all Shares for all purposes (except for tax purposes).

Investors owning Shares are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for 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 stock 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 upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other stocks that you hold in book-entry or “street name” form.

How to Buy and Sell Shares

Pricing Fund Shares

The trading price of each Fund’s Shares on the NYSE Arca may differ from a Fund’s daily NAV and can be affected by market forces of supply and demand, economic conditions and other factors.

The NYSE Arca disseminates the approximate value of Shares of each Fund every fifteen seconds. The approximate value calculations are based on local market prices and may not reflect events that occur subsequent to the local market’s close. As a result, premiums and discounts between the approximate value and the market price could be affected. This approximate value should not be viewed as a “real time” update of the NAV per Share of a Fund because the approximate value may not be calculated in the same manner as the NAV, which is computed once a day, generally at the end of the business day. The Funds are not involved in, or responsible for, the calculation or dissemination of the approximate value and the Funds do not make any warranty as to its accuracy.

The NAV per Share for each Fund is determined once daily as of the close of the New York Stock Exchange (“NYSE”), usually 4:00 p.m. Eastern time, each day the NYSE is open for trading, provided that (a) any assets or liabilities denominated in currencies other than the U.S. dollar shall be translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more major banks or dealers that makes a two-way market in such currencies (or a data service provider based on quotations received from such banks or dealers); and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments on any day that the Securities Industry and Financial Markets Association announces an early closing time. NAV per Share is determined by dividing the value of a Fund’s

portfolio securities, cash and other assets (including accrued interest), less all liabilities (including accrued expenses), by the total number of Shares outstanding.

Each Fund’s equity securities are valued at the last reported sale price on the principal exchange on which such securities are traded, as of the close of regular trading on the NYSE on the day the securities are being valued or, if there are no sales, at the mean of the most recent bid and asked prices. Equity securities that are traded in over the counter markets are valued at the last quoted sales price in the markets in which they trade or, if there are no sales, at the mean of the most recent bid and asked prices. For securities traded on NASDAQ, the NASDAQ Official Closing Price generally will be used. Mutual funds, such as government money market funds, are valued at their last closing net asset value. Short-term securities with a maturity of 60 days or less are valued on the basis of amortized cost provided such amount approximates market value. Securities for which market quotations (or other market valuations such as those obtained from a pricing service) are not readily available, including restricted securities, are valued by a method that the Trustees believe accurately reflects fair value. Securities will be valued at fair value when market quotations (or other market valuations such as those obtained from a pricing service) are not readily available or are deemed unreliable, such as when a security’s value or meaningful portion of a Fund’s portfolio is believed to have been materially affected by a significant event. Such events may include a natural disaster, an economic event like a bankruptcy filing, a trading halt in a security, an unscheduled early market close or a substantial fluctuation in domestic and foreign markets that has occurred between the close of the principal exchange and the NYSE. In such a case, the value for a security is likely to be different from the last quoted market price. This, in turn, could lead to differences between the market price of a Fund’s shares and the underlying value of those shares. In addition, due to the subjective and variable nature of fair market value pricing, it is possible that the value determined for a particular asset may be materially different from the value realized upon such asset’s sale.

Debt securities, if any, are valued at market value. Market value generally means a valuation (i) obtained from an exchange, a pricing service or a major market maker (or dealer), (ii) based on a price quotation or other equivalent indication of value supplied by an exchange, a pricing service or a major market maker (or dealer) or (iii) based on amortized cost. Each Fund’s debt securities, if any, are thus valued by reference to a combination of transactions and quotations for the same or other securities believed to be comparable in quality, coupon, maturity, type of issue, call provisions, trading characteristics and other features deemed to be relevant. To the extent a Fund’s debt securities are valued based on price quotations or other equivalent indications of value provided by a third-party pricing service, any such third-party pricing service may use a variety of methodologies to value some or all of a Fund’s debt securities to determine the market price. For example, the prices of securities with characteristics similar to those held by a Fund may be used to assist with the pricing process. In addition, the pricing service may use proprietary pricing models.

Trading in securities on many foreign securities exchanges and over the counter markets is normally completed before the close of business on each U.S. business day. In addition, securities trading in a particular country or countries may not take place on all U.S. business days or may take place on days that are not U.S. business days. Changes in valuations on certain securities may occur at times or on days on which a Fund’s net asset value is not calculated and on which a Fund does not effect sales, redemptions and exchanges of its Shares.

Creation Units

Investors such as market makers, large investors and institutions who wish to deal in Creation Units (large specified blocks of Shares) directly with a Fund must have entered into an authorized participant agreement (such investors being “Authorized Participants” or “APs”) with ALPS Portfolio Solutions Distributor, Inc. (the “Distributor”) and be accepted by the transfer agent, or purchase through a dealer that has entered into such an agreement. Set forth below is a brief description of the procedures applicable to purchase and redemption of Creation Units. For more detailed information, see “Creation and Redemption of Creation Unit Aggregations” in the Statement of Additional Information.

How to Buy Shares

In order to purchase Creation Units of a Fund, an AP must generally deposit a designated portfolio of securities (the “Deposit Securities”) and generally make a cash payment referred to as the “Cash Component.” To the extent permitted or specified, cash in lieu of some or all of the Deposit Securities, or substitution of securities, may be available. The list of the names and the amounts of the Deposit Securities is made available by the Fund’s custodian through the facilities of the National Securities Clearing Corporation (the “NSCC”) immediately prior to the opening of business each day of the NYSE Arca. The Cash Component represents the difference between the NAV of a Creation Unit and the market value of the Deposit Securities.

Orders must be placed in proper form by or through either (i) a “Participating Party,” i.e., a broker-dealer or other participant in the Clearing Process of the Continuous Net Settlement System of the NSCC (the “Clearing Process”) or (ii)  a participant of the DTC (“DTC Participant”) that has entered into an agreement with the Distributor, and accepted by the transfer agent, with respect to purchases and redemptions of Creation Units. All standard orders must be placed for one or more whole Creation Units of Shares of a Fund and must be received by the Distributor in proper form no later than the close of regular trading on the NYSE (ordinarily 4:00 p.m. Eastern time) (“Closing Time”) in order to receive that day’s closing NAV per Share. In the case of custom orders, as further described in the Statement of Additional Information, the order must be received by the Distributor no later than one hour prior to Closing Time in order to receive that day’s closing NAV per Share. A custom order may be placed by an Authorized Participant in the event that the Trust permits or requires the substitution of securities or the substitution of an amount of cash to be added to the Cash Component to replace any Deposit Security which may not be available in sufficient

quantity for delivery or which may not be eligible for trading by such AP or the investor for which it is acting or any other relevant reason.

A fixed creation transaction fee of $300 per transaction (the “Creation Transaction Fee”) is applicable to each transaction regardless of the number of Creation Units purchased in the transaction. An additional variable charge for transactions effected outside the Clearing Process or for cash creations or partial cash creations may also be imposed to compensate a Fund for the costs associated with buying the applicable securities. Each Fund may adjust these fees from time to time based on actual experience. The price for each Creation Unit will equal the daily NAV per Share times the number of Shares in a Creation Unit plus the fees described above and, if applicable, any transfer taxes.

Shares of a Fund may be issued in advance of receipt of all Deposit Securities subject to various conditions, including a requirement to maintain cash at least equal to 115% of the market value of the missing Deposit Securities on deposit with the Trust.

For more detailed information, see “Creation and Redemption of Creation Unit Aggregations” in the Statement of Additional Information.

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 a Fund’s discretion, be permitted to deposit an equivalent amount of cash in substitution for any security which would otherwise be included in the Deposit Securities applicable to the purchase of a Creation Unit. For more detailed information, see “Creation and Redemption of Creation Unit Aggregations” in the Statement of Additional Information.

Redemption of Shares

Shares may be redeemed only in Creation Units at their NAV and only on a day the NYSE Arca is open for business. The Funds’ custodian makes available immediately prior to the opening of business each day of the NYSE Arca, through the facilities of the NSCC, the list of the names and the amounts of the Fund’s portfolio securities that will be applicable that day to redemption requests in proper form (“Fund Securities”). Fund Securities received on redemption may not be identical to Deposit Securities, which are applicable to purchases of Creation Units. Unless cash redemptions or partial cash redemptions are available or specified for a Fund as set forth below, the redemption proceeds consist of the Fund Securities, plus cash in an amount equal to the difference between the NAV of Shares being redeemed as next determined after receipt by the transfer agent of a redemption request in proper form, and the value of the Fund Securities (the “Cash Redemption Amount”), less the applicable redemption fee and, if applicable, any transfer taxes. Should the Fund Securities have a value greater than the NAV of Shares being redeemed, a compensating cash payment to a Fund equal to the differential, plus the applicable redemption fee and, if applicable, any transfer taxes will be required to be arranged for, by or on behalf of the redeeming shareholder.

An order to redeem Creation Units of a Fund may only be effected by or through an Authorized Participant. An order to redeem must be placed for one or more whole Creation Units and must be received by the transfer agent in proper form no later than the close of regular trading on the NYSE (normally 4:00 p.m. Eastern time) in order to receive that day’s closing NAV per Share. In the case of custom orders, as further described in the Statement of Additional Information, the order must be received by the transfer agent no later than 3:00 p.m. Eastern time.

A fixed redemption transaction fee of $300 per transaction (the “Redemption Transaction Fee”) is applicable to each redemption transaction regardless of the number of Creation Units redeemed in the transaction. An additional variable charge for cash redemptions or partial cash redemptions may also be imposed to compensate a Fund for the costs associated with selling the applicable securities. Each Fund may adjust these fees from time to time based on actual experience. Each Fund reserves the right to effect redemptions wholly or partially in cash. A shareholder may request a cash redemption or partial cash redemption in lieu of securities, however, a Fund may, in its discretion, reject any such request.

For more detailed information, see “Creation and Redemption of Creation Unit Aggregations” in the Statement of Additional Information.

Payments to Broker-Dealers and Other Financial Intermediaries 

The Adviser, the Sub-Adviser, or their affiliates may make payments to broker-dealers or other financial intermediaries (each, an “Intermediary”) related to marketing activities and presentations, educational training programs, the support of technology platforms and/ or reporting systems, or their making shares of the Fund and certain other series of the Trust available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by the Adviser, the Sub-Adviser, or their affiliates from their own resources, which come directly or indirectly in part from fees paid by the Trust, including the Fund. Payments of this type are sometimes referred to as revenue-sharing payments. An Intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an Intermediary create conflicts of interest between the Intermediary and its customers and may cause the Intermediary to recommend the Fund or other series of the Trust over another investment. More information regarding these payments is contained in the SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from the Adviser, the Sub-Adviser, or their affiliates.

Distributions

Dividends and Capital Gains. Fund shareholders are entitled to their share of a Fund’s income and net realized gains on its investments. Each Fund pays out substantially all of its net earnings to its shareholders as “distributions.”

Each Fund typically earns interest from debt securities. These amounts, net of expenses, are passed along to Fund shareholders as “income dividend distributions.” Each Fund realizes capital gains or losses whenever it sells securities. Net long term capital gains are distributed to shareholders as “capital gain distributions.”

Income dividends, if any, are distributed to shareholders monthly. Net capital gains are distributed at least annually. Dividends may be declared and paid more frequently to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended. Some portion of each distribution may result in a return of capital (which is a return of the shareholder’s investment in the Fund). Fund shareholders will be notified regarding the portion of the distribution that represents a return of capital. Shareholders should read any written disclosure provided pursuant to Section 19(a) of and Rule 19a-1 under the 1940 Act carefully, and should not assume that the source of any distribution from a Fund is net profit.

Distributions in cash may be reinvested automatically in additional whole Shares only if the broker through which the Shares were purchased makes such option available.

Frequent Purchases and Redemptions

The Funds impose no restrictions on the frequency of purchases and redemptions. The Board of Trustees evaluated the risks of market timing activities by the Funds’ shareholders when they determined that no restriction or policy was necessary. The Board noted that the Funds’ Shares can only be purchased and redeemed directly from a Fund in Creation Units by APs and that the vast majority of trading in the Funds’ Shares occurs on the secondary market. Because the secondary market trades do not involve a Fund directly, it is unlikely those trades would cause many of the harmful effects of market timing, including dilution, disruption of portfolio management, increases in the Funds’ trading costs and the realization of capital gains. To the extent a Fund may effect the purchase or redemption of Creation Units in exchange wholly or partially for cash, the Board noted that such trades could result in dilution to a Fund and increased transaction costs, which could negatively impact a Fund’s ability to achieve its investment objective. However, the Board noted that direct trading by APs is critical to ensuring that the Fund’s Shares trade at or close to NAV. In addition, each Fund imposes fixed and variable transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by a Fund in effecting trades.

Fund Service Providers

ALPS Fund Services, Inc. is the administrator and fund accounting agent of the Funds.

State Street Bank and Trust Company is the custodian and transfer agent for the Funds.

Dechert LLP serves as counsel to the Funds.

Deloitte & Touche LLP served as the Funds’ independent registered public accounting firm. The independent registered public accounting firm is responsible for auditing the annual financial statements of the Funds.

Federal Income Taxation

As with any investment, you should consider how your investment in Shares will be taxed. The tax information in this Prospectus is provided as general information. You should consult your own tax professional about the tax consequences of an investment in Shares.

Unless your investment in the Shares is made through a tax exempt entity or tax deferred retirement account, such as an IRA plan, you need to be aware of the possible tax consequences when:

Taxes on Distributions

Dividends from net investment income, if any, are declared and paid monthly. Each Fund may also pay a special distribution at the end of the calendar year to comply with federal tax requirements. In general, your distributions are subject to federal income tax when they are paid, whether you take them in cash or reinvest them in a Fund. Dividends paid out of each Fund’s income and net short term capital gains, if any, are taxable as ordinary income. Distributions of net long term capital gains, if any, in excess of net short term capital losses are taxable as long term capital gains, regardless of how long you have held the Shares.

The maximum individual rate applicable to long term capital gains is either 15% or 20%, depending on whether the individual’s income exceeds certain threshold amounts. In addition, some ordinary dividends declared and paid by a Fund to non-corporate shareholders may qualify for taxation at the lower reduced tax rates applicable to long term capital gains, provided that holding period and other requirements are met by the relevant Fund and the shareholder. Dividends received by the Funds from a REIT generally will not constitute qualified dividend income.

An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from a Fund and net gains from redemptions or other taxable dispositions of Fund Shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds certain threshold amounts.

Distributions in excess of a Fund’s current and accumulated earnings and profits are treated as a tax free return of capital to the extent of your basis in the Shares, and as capital gain thereafter.

A distribution will reduce a Fund’s NAV per Share and may be taxable to you as ordinary income or capital gain even though, from an investment standpoint, the distribution may constitute a return of capital.

If you are not a citizen or permanent resident of the United States, or if you are a foreign entity, a Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies or unless such income is effectively connected with a U.S. trade or business. Prospective investors are urged to consult their tax advisors concerning the applicability of the U.S. withholding tax.

A Fund generally would be required to withhold a percentage of your distributions and proceeds if you have not provided a taxpayer identification number (generally your social security number) or otherwise provide proof of an applicable exemption from backup withholding. The backup withholding rate for an individual is 24%.

Taxes on Exchange-Listed Shares Sales

Currently, any capital gain or loss realized upon a sale of Shares is generally treated as long term capital gain or loss if the Shares have been held for more than one year and as short term capital gain or loss if the Shares have been held for one year or less. The ability to deduct capital losses may be limited.

Taxes on Purchase and Redemption of Creation Units

An Authorized Participant who exchanges equity securities for Creation Units generally will recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time of the exchange and the exchanger’s aggregate basis in the securities surrendered and the Cash Component paid. A person who exchanges Creation Units for equity securities will generally recognize a gain or loss equal to the difference between the exchanger’s basis in the Creation Units and the aggregate market value of the securities received and the Cash Redemption Amount. The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for Creation Units 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 advisor with respect to whether the wash sale rules apply and when a loss might be deductible.

If you purchase or redeem Creation Units, you will be sent a confirmation statement showing how many and at what price you purchased or sold Shares.

The foregoing discussion summarizes some of the possible consequences under current federal tax law of an investment in a Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions, and sales of Fund Shares. Consult your personal tax advisor about the potential tax consequences of an investment in Fund Shares under all applicable tax laws. Changes in applicable tax authority could materially affect the conclusions discussed above and could adversely affect the Fund, and such changes often occur.

Other Information

For purposes of the 1940 Act, a Fund is treated as a registered investment company. Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies, including Shares of each Fund. In reliance on an SEC exemptive order or rules under Section 12(d)(1) of the 1940 Act, registered investment companies may invest in exchange-traded funds offered by the Trust beyond the limits of Section 12(d)(1) subject to certain terms and conditions.

Disclosure of Portfolio Holdings

Each Fund’s portfolio holdings will be disclosed each day on its website at www.alpsfunds.com. A description of the Trust’s policies and procedures with respect to the disclosure of each Fund’s portfolio securities is available in the Funds’ Statement of Additional Information.

Premium/Discount Information

Information regarding how often the Shares of each Fund traded on the NYSE Arca at a price above (i.e., at a premium) or below (i.e., at a discount) the NAV of each Fund during the most recently completed calendar year and subsequent quarters, when available, will be available at www.alpsfunds.com.
