FUND SUMMARY
 
 
Janus Henderson Sustainable Corporate Bond ETF
Ticker:    SCRD
 
INVESTMENT OBJECTIVE
Janus Henderson Sustainable Corporate Bond ETF seeks total return consisting of income and capital appreciation, while giving special consideration to certain environmental, social and governance (“ESG”) factors.
 
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. Investors may pay brokerage commissions and other fees to financial intermediaries on their purchases and sales of Fund shares, which are not reflected in the table or in the example below.
 
ANNUAL FUND OPERATING EXPENSES
(expenses that you pay each year as a percentage of the value of your investment)
       
Management Fees
     0.35%  
Other Expenses
     0.00%  
Total Annual Fund Operating Expenses
     0.35%  
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
 
      1 Year      3 Years      5 Years      10 Years  
   $   36      $   113      $   197      $   443  
Portfolio Turnover:  The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 92% of the average value of its portfolio.
 
PRINCIPAL INVESTMENT STRATEGY
The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. dollar denominated corporate bonds and commercial paper of various maturities. Under normal circumstances, no more than 15% of the Fund’s net assets will be invested in securities rated below investment grade (sometimes referred to as “junk” bonds); however, such bonds will have a minimum rating of B- by a Nationally Recognized Statistical Ratings Organization (“NRSRO”) or, if unrated, determined to be of comparable credit quality by the Adviser. The Fund seeks to invest in debt instruments issued by companies that the Adviser believes exhibit sustainable business practices. As discussed further below, the portfolio managers seek to select securities that align with certain positive social and environmental themes. In identifying investment opportunities for the Fund, the portfolio managers use a proprietary multi-factor sustainability framework, along with an analysis of fundamental business and credit quality factors, to guide both security selection and overall portfolio composition. The sustainability framework incorporates thematic investing, exclusions, positive tilting, sector- and issuer-level environmental, social and governance factor analysis and issuer engagement considerations as determined by the Adviser, as discussed further below. The Fund may, but is not required to, invest in so-called “labeled bonds”, which include debt where the proceeds have been specifically earmarked for ESG-themed purposes (“Use of Proceeds” bonds), or the returns are specifically tied to defined sustainable or environmental key performance indicators (“KPI-linked bonds”). 
 
2½Janus Henderson Sustainable Corporate Bond ETF

The Fund will invest principally in investment grade bonds. An investment grade corporate bond is a company-issued bond rated Baa3/BBB- or higher by a NRSRO or, if unrated, determined to be of comparable credit quality by the Adviser. An NRSRO is a credit rating agency that is registered with the Securities and Exchange Commission (“SEC”) that issues credit ratings that the SEC permits other financial firms to use for certain regulatory purposes. The Fund may invest up to 20% of its net assets in other domestic or foreign debt securities, including U.S. Treasuries, bank loans, and cash and cash alternatives. 
The Fund may concentrate its portfolio investments in any one industry or group of industries under certain circumstances. Generally, the Fund will not invest more than 25% of the value of its total assets in the securities of companies conducting their principal business activities in the same industry, except that, to the extent that an industry represents 20% or more of the Fund’s benchmark at the time of investment, the Fund may invest up to 35% of its total assets in that industry. The Fund’s primary benchmark index is the Bloomberg U.S. Corporate Bond Index. Under normal circumstances, the Fund will seek to maintain an average portfolio duration (price sensitivity to changes in interest rates) of plus or minus 3 years as compared to the Bloomberg U.S. Corporate Bond Index. As of October 31, 2022, the duration of the Bloomberg U.S. Corporate Bond Index was 7.37 years. Please refer to the Glossary of Investment Terms for additional information about duration. 
In selecting investments, the portfolio managers employ a combination of “bottom up” fundamental security selection with a “top down” thematic approach, focusing on positive social and environmental themes. To identify the universe of investible securities for the Fund, the portfolio managers first apply broad-based negative screens, which incorporate third-party inputs, to seek to avoid (i) securities of issuers that are non-compliant with the UN Global Compact, and/or (ii) securities of issuers that, in the determination of the Adviser, are significantly engaged in or derive more than de minimis revenue from (or securitized products the economic value of which is tied in more than de minimis fashion to) industries, activities or assets considered by the Adviser or the portfolio managers to have a negative impact on society or the environment. A current list of such activities, which may evolve over time, follows: 
 
 
alcohol; 
 
animal testing (cosmetics); 
 
chemicals of concern; 
 
contentious industries (limited to excluding companies that produce palm oil); 
 
controversial armaments; 
 
controversial fossil fuel extraction and refining; 
 
controversial fossil fuel power generation; 
 
fur; 
 
gambling; 
 
genetic engineering; 
 
pornography; 
 
tobacco production; and 
 
United Nations Global Compact violators. 
Thereafter, the portfolio managers assess each issuer’s approach to positive sustainable business practices and seek to select securities that align with certain positive social and environmental themes, which are informed by the United Nations Sustainable Development Goals (“UNSDGs”). These themes of focus, which may evolve over time and/or incorporate other themes aligned with the UNSDGs, include the following: 
 
 
Transition to a Green Economy, including the development of clean energy and sustainable transportation and cities; 
 
 
Economic and Community Development and Inclusion, which includes financial services and infrastructure that are integral in the development of a sustainable economy; 
 
 
Knowledge & Technology, and Innovation, which includes technological advancements that can enable a transition to more sustainable business practices for companies across industries, such as software and semiconductors and industry specific innovation; and 
 
 
Health & Well-Being, which includes increased access to healthcare, and innovation for medical treatment and health. 
The portfolio managers consider companies that are considered sustainability practice leaders in their respective industries, as well as companies looking to transition to more sustainable business practices or models. These selection criteria will be identified primarily through the Adviser’s fundamental research process, which incorporates third party data, analysis and 
 
3½Janus Henderson Sustainable Corporate Bond ETF

ratings. In constructing a portfolio that seeks to provide excess returns, the portfolio managers will consider other ESG factors, such as the overall carbon footprint of the portfolio based on available data on such factors. 
Under normal circumstances, the Fund will generally sell or dispose of portfolio investments when, in the opinion of the Adviser, they (i) no longer present attractive investment opportunity (e.g., they have reached their expected value, or where better relative value exists elsewhere, or as the result of changing market conditions); and/or (ii) no longer meet the Fund’s ESG and/or sustainable criteria. Decisions with respect to the timing of such dispositions shall be made by the Fund’s portfolio managers taking into account the best interests of Fund shareholders. 
The Fund may use derivatives, including, but not limited to, swaps (including interest-rate swaps, total rate of returns swaps and credit default swaps), swaptions, options, futures, and options on futures, which may be used for risk, duration and yield-curve management, or to enhance expected returns. Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, interest rates, currencies, or market indices. 
The Fund may enter into reverse-repurchase agreements and use the proceeds to invest in securities consistent with the Fund’s principal investment strategies. The Fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale (these are known as “restricted securities”), which may include Rule 144A securities. 
The Fund may invest its uninvested cash in affiliated or non-affiliated money market funds (or private funds operating as money market funds) and/or affiliated or unaffiliated exchange-traded funds (“ETFs”). 
The portfolio managers do not apply the ESG factors noted above in managing the Fund’s cash and exposure to U.S. Treasuries and certain derivatives, such as credit default swaps on indices or derivatives used to manage interest rate risk. 
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions on a short-term or long-term basis, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination. 
 
PRINCIPAL INVESTMENT RISKS
The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. The principal risks associated with investing in the Fund are set forth below.
Corporate Bond Risk.  The investment return of corporate bonds reflects interest earned on the security and changes in the market value of the security. The market value of a corporate bond may be affected by changes in interest rates, the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the marketplace. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates. The market value of intermediate and longer-term corporate bonds is generally more sensitive to changes in interest rates than is the market value of shorter-term corporate bonds. Corporate bonds are also subject to the credit risk of the issuer, as the issuer of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.
Fixed-Income Securities Risk. The Fund invests in a variety of debt and other fixed-income securities that are generally subject to the following risks:
  
 
Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. The United States is currently experiencing a rising interest rate environment, which may increase the Fund’s exposure to risks associated with rising interest rates. Rising interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. 
 
 
Credit risk is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default. 
 
 
Prepayment risk is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential. 
 
 
Valuation risk is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security. 
 
4½Janus Henderson Sustainable Corporate Bond ETF

 
Extension risk is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall. 
 
 
Liquidity risk is the risk that fixed-income securities may be difficult or impossible to sell at the time that the portfolio managers would like or at the price the portfolio managers believe the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). 
Market Risk.  The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value (“NAV”) may decrease. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as terrorism, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics, including COVID-19) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money. 
High-Yield/High-Risk Bond Risk.  High-yield/high-risk bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value. 
Sustainable Investment Risk.  The Fund follows a sustainable investment approach by investing in debt securities that the Adviser believes are aligned with certain positive environmental and social impact themes and/or the debt of companies with business practices that the Adviser believes to be sustainable and/or companies that demonstrate adherence to certain sustainable business and/or ESG-related practices. Accordingly, the Fund may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector, which may make the Fund more vulnerable to unfavorable developments in a particular sector than funds that invest more broadly. Additionally, due to its exclusionary criteria, the Fund may not be invested in certain industries or sectors, and therefore may have lower performance than portfolios that do not apply similar criteria. In addition, because sustainable and ESG investing takes into consideration factors beyond traditional financial analysis, the investment opportunities for the Fund may be limited at times. Sustainability and ESG-related information provided by issuers and third parties, upon which the portfolio managers may rely, continues to develop, and may be incomplete, inaccurate, use different methodologies or be applied differently across companies and industries. Further, the regulatory landscape for sustainable and ESG investing in the United States is still developing and future rules and regulations may require the Fund to modify or alter its investment process. Similarly, government policies incentivizing companies to engage in sustainable and ESG practices may fall out of favor, which could potentially limit the Fund’s investment universe. There is also a risk that the companies identified through the investment process may fail to adhere to sustainable and/or ESG-related business practices, which may result in the Fund selling a security when it might otherwise be disadvantageous to do so. 
Industry and Sector Risk.  The Fund may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector or that benefit from the same theme. Companies in the same industry or economic sector or that benefit from the same theme may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments than funds that invest more broadly. As the Fund’s portfolio becomes more concentrated, the Fund is less able to spread risk and potentially reduce the risk of loss and volatility. 
Portfolio Management Risk.  The Fund is an actively managed investment portfolio and is therefore subject to the risk that the portfolio managers may not be successful in identifying investment opportunities that are aligned with the sustainable investment approach that the Fund employs. The Fund may underperform its benchmark index or other funds with similar investment objectives. 
Derivatives Risk.  Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage because leverage can exaggerate the effect of any increase or decrease in the value of securities and other instruments held by the Fund. Derivatives also involve the risk that the counterparty to the derivative transaction will default on its payment obligations. Derivatives used 
 
5½Janus Henderson Sustainable Corporate Bond ETF

for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by the portfolio managers or if the cost of the derivative outweighs the benefit of the hedge. 
Restricted Securities Risk.  Investments in restricted securities, including securities issued under Regulation S and Rule 144A, could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Restricted securities may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available. 
Foreign Exposure Risk.  Foreign securities, including emerging markets, can be more volatile than the U.S. market. As a result, the Fund’s returns and NAV may be affected to a large degree by political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in foreign debt securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk and may be more sensitive to changes in interest rates than domestic securities. Additionally, investments in securities of foreign governments involve the risk that a foreign government may not be willing or able to pay interest or repay principal when due. The Fund’s investments in emerging market countries, if any, may involve risks greater than, or in addition to, the risks of investing in more developed countries. 
Concentration Risk.  The Fund will not invest more than 25% of the value of its total assets in the securities of companies within the same industry, except that, to the extent that an industry represents 20% or more of the Fund’s benchmark at the time of investment, the Fund may invest up to 35% of its assets in that industry. To the extent the Fund invests a substantial portion of its assets in an industry or group of industries, market or economic factors impacting that industry or group of industries could have significant effect on the value of the Fund’s investments. Companies in the same or similar industries may share common characteristics and are more likely to react similarly to industry-specific market or economic developments. Additionally, the Fund’s performance may be more volatile when its investments are less diversified across industries. 
Reverse Repurchase Agreement Risk.  Reverse repurchase agreements are transactions in which the Fund sells a security and simultaneously commits to repurchase that security from the buyer, such as a bank or broker-dealer, at an agreed upon price on an agreed upon future date. The repurchase price consists of the sale price plus an incremental amount reflecting the interest cost to the Fund on the proceeds it has received from the initial sale. Reverse repurchase agreements involve the risk that the value of securities that the Fund is obligated to repurchase under the agreement may decline below the repurchase price. Additionally, such transactions are only advantageous if the interest cost to the Fund of the reverse repurchase transaction is less than the cost of obtaining the cash otherwise. Interest costs on the proceeds received in a reverse repurchase agreement may exceed the return received on the investments made by the Fund with those proceeds, resulting in reduced returns to shareholders. When the Fund enters into a reverse repurchase agreement, it is subject to the risk that the buyer (counterparty) may default on its obligations to the Fund. In the event of such a default, the Fund may experience delays, costs, and losses, all of which may reduce returns to shareholders. Investing reverse repurchase proceeds may also have a leveraging effect on the Fund’s holdings. The Fund’s use of leverage can magnify the effect of any gains or losses, causing the Fund to be more volatile than if it had not been leveraged. There is no assurance that any leveraging strategy used by the Fund will be successful. 
Leverage Risk.  Leverage can magnify the effect of any gains or losses, causing the Fund to be more volatile than if it had not been leveraged. Certain commodity-linked derivatives may subject the Fund to leveraged market exposure to commodities. In addition, the Fund’s assets that are used as collateral to secure short sale transactions may decrease in value while the short positions are outstanding, which may force the Fund to use its other assets to increase collateral. There is no assurance that a leveraging strategy will be successful. 
LIBOR Replacement Risk.  Certain debt securities, derivatives, or other financial instruments utilize the London Inter-Bank Offered Rate (“LIBOR”) as a reference rate for various rate calculations. The U.K. Financial Conduct Authority has ceased to publish or maintain as representative many LIBOR settings, and will phase out certain other commonly-used U.S. dollar LIBOR settings as of June 30, 2023. The elimination of LIBOR or other reference rates and the transition process away from LIBOR could adversely impact (i) volatility and liquidity in markets that are tied to those reference rates, (ii) the market for, or value of, specific securities or payments linked to those reference rates, (iii) the availability or terms of borrowing or refinancing, or (iv) the effectiveness of hedging strategies. For these and other reasons, the elimination of LIBOR or other reference rates may 
 
6½Janus Henderson Sustainable Corporate Bond ETF

adversely affect the Fund’s performance and/or NAV. Alternatives to LIBOR are established or in development in most major currencies including the Secured Overnight Financing Rate (“SOFR”) that is intended to replace the U.S. dollar LIBOR. 
The effect of the discontinuation of LIBOR or other reference rates on the Fund will vary depending on, among other things (i) existing fallback or termination provisions in individual contracts and (ii) whether, how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new products and instruments. Accordingly, it is difficult to predict the full impact of the transition away from LIBOR or other reference rates on the Fund until new reference rates and fallbacks for both legacy and new products, instruments and contracts are commercially accepted. 
Smaller Sized Fund Risk.  Because the Fund has a small asset base, large inflows and outflows may have a disproportionate impact, negative or positive, on the Fund’s performance, which may be more volatile than that of a larger fund. If a smaller fund were to fail to attract sufficient assets to achieve or maintain economies of scale, performance may be negatively impacted, and any resulting liquidation could create negative transaction costs for the Fund and tax consequences for investors. 
Securities Lending Risk.  Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund lends its securities and is unable to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Any cash received as collateral for loaned securities will be invested in an affiliated cash management vehicle or time deposits. This investment is subject to market appreciation or depreciation and the Fund will bear any loss on the investment of its cash collateral. 
Exchange Listing and Trading Issues Risk.  Although Fund shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”), there can be no assurance that an active trading market for such shares will develop or be maintained. The lack of an active market for Fund shares, as well as periods of high volatility, disruptions in the creation/redemption process, or factors affecting the liquidity of the underlying securities held by the Fund, may result in the Fund’s shares trading at a premium or discount to its NAV. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund shares inadvisable. In addition, trading is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the Fund’s listing will continue to be met or will remain unchanged. 
Fluctuation of NAV and Market Price Risk.  The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s securities holdings. The market prices of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s NAV and supply and demand of shares on the Exchange. Volatile market conditions, an absence of trading in shares of the Fund, or a high volume of trading in the Fund, may result in trading prices in the Fund’s shares that differ significantly from the Fund’s NAV. Additionally, during a “flash crash,” the market prices of the Fund’s shares may decline suddenly and significantly, resulting in Fund shares trading at a substantial discount to NAV. Such a decline may not reflect the performance of the portfolio securities held by the Fund. Flash crashes may cause Authorized Participants and other market makers to limit or cease trading in the Fund’s shares for temporary or longer periods, which may result in an increase in the variance between market prices of the Fund’s shares and the Fund’s NAV. Shareholders could suffer significant losses to the extent that they sell shares at these temporarily low market prices. 
It cannot be predicted whether Fund shares will trade below, at or above the Fund’s NAV. Further, the securities held by the Fund may be traded in markets that close at a different time than the Exchange. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the Exchange is open but after the applicable market closing or fixing settlement times, bid-ask spreads and the resulting premium or discount to the Fund shares’ NAV is likely to widen. Similarly, the Exchange may be closed at times or days when markets for securities held by the Fund are open, which may increase bid-ask spreads and the resulting premium or discount to the Fund shares’ NAV when the Exchange re-opens. The Fund’s bid-ask spread and the resulting premium or discount to the Fund’s NAV may also be impacted by the liquidity of the underlying securities held by the Fund, particularly in instances of significant volatility of the underlying securities. 
Authorized Participant Risk.  The Fund may have a limited number of financial institutions that may act as Authorized Participants (“APs”). Only APs who have entered into agreements with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund. These APs have no obligation to submit creation or redemption orders and, as a result, there is no assurance that an active trading market for the Fund’s shares will be established or maintained. This risk may be heightened to the extent that the securities underlying the Fund are traded outside of a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be willing or able to do. Additionally, to the extent that those APs exit 
 
7½Janus Henderson Sustainable Corporate Bond ETF

the business or are unable to process creation and/or redemption orders, and no other AP is able to step forward to create and redeem in either of these cases, shares may trade like closed-end fund shares at a premium or a discount to NAV and possibly face delisting. 
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.

PURCHASE AND SALE OF FUND SHARES
The Fund is an actively-managed Exchange-Traded Fund (“ETF”). Unlike shares of traditional mutual funds, shares of the Fund are not individually redeemable and may only be purchased or redeemed directly from the Fund at NAV in large increments called “Creation Units” through APs and the Adviser may modify the Creation Unit size with prior notification to the Fund’s APs. See the ETF portion of the Janus Henderson website for the Fund’s current Creation Unit size. Creation Unit transactions are conducted in exchange for the deposit or delivery of a designated portfolio of in-kind securities with a cash balancing amount and/or all cash. Except when aggregated in Creation Units, Fund shares are not redeemable securities of the Fund. Shares of the Fund are listed and trade on the Exchange, and individual investors can purchase or sell shares in much smaller increments for cash in the secondary market through a broker-dealer. These transactions, which do not involve the Fund, are made at market prices that may vary throughout the day and differ from the Fund’s NAV. As a result, you may pay more than NAV (at a premium) when you purchase shares, and receive less than NAV (at a discount) when you sell shares, in the secondary market.
Investors purchasing or selling shares in the secondary market may also incur additional costs, including brokerage commissions and an investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”). Historical information regarding the Fund’s bid/ask spread can be accessed on the Fund’s website at janushenderson.com/performance by selecting the Fund.
 
TAX INFORMATION
The Fund’s distributions are generally taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed at ordinary income tax rates upon withdrawal of your investment from such account). A sale of Fund shares may result in a capital gain or loss.
 
PAYMENTS TO BROKER‑DEALERS AND OTHER FINANCIAL INTERMEDIARIES
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Adviser and/or its affiliates may pay broker-dealers or intermediaries for the sale and/or maintenance of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

FUND SUMMARY
 
 
Janus Henderson Sustainable & Impact Core Bond ETF
Ticker: JIB
 
INVESTMENT OBJECTIVE
Janus Henderson Sustainable & Impact Core Bond ETF seeks total return consisting of income and capital appreciation, while giving special consideration to certain environmental, social and governance (“ESG”) factors.
 
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. Investors may pay brokerage commissions and other fees to financial intermediaries on their purchases and sales of Fund shares, which are not reflected in the table or in the example below.
 
ANNUAL FUND OPERATING EXPENSES
(expenses that you pay each year as a percentage of the value of your investment)
       
Management Fees
     0.39%  
Other Expenses
     0.00%  
Total Annual Fund Operating Expenses
     0.39%  
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
 
1 Year    3 Years      5 Years      10 Years  
40
   $   125      $   219      $   493  
Portfolio Turnover:  The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 138% of the average value of its portfolio.
 
PRINCIPAL INVESTMENT STRATEGY
The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds. For purposes of this 80% policy, the term bonds refers to a variety of fixed-income securities and instruments of all types and maturities, including, but not limited to, mortgage-backed securities, asset-backed securities, corporate bonds, U.S. Treasury obligations, U.S. government and agency securities, commercial paper, loan interests, and funds that invest in short-term debt (such as money market funds). The Fund seeks to provide risk-adjusted returns that will outperform the Fund’s benchmark while achieving certain positive social and environmental impact objectives, as discussed below.
In identifying investment opportunities for the Fund, the portfolio managers use a proprietary multi-factor sustainability framework, along with an analysis of fundamental business and credit quality factors, to guide both security selection and overall portfolio composition. The sustainability framework incorporates thematic investing, exclusions, positive tilting, sector- and issuer-level environmental, social and governance factor analysis and issuer engagement considerations as determined by the Adviser, as discussed further below. The Fund may, but is not required to, invest in so-called “labeled bonds”, which include 
 
10½Janus Henderson Sustainable & Impact Core Bond ETF

debt where the proceeds have been specifically earmarked for ESG-themed purposes (“Use of Proceeds” bonds), or the returns are specifically tied to defined sustainable or environmental key performance indicators (“KPI-linked bonds”). 
The Fund will invest principally in investment grade bonds. An investment grade bond is a fixed-income or other debt security rated Baa3/BBB- or higher by a Nationally Recognized Statistical Ratings Organization (“NRSRO”) or, if unrated, determined to be of comparable credit quality by the Adviser. An NRSRO is a credit rating agency that is registered with the Securities and Exchange Commission (“SEC”) that issues credit ratings that the SEC permits other financial firms to use for certain regulatory purposes. The Fund may also invest up to 5% of its assets in securities rated below investment grade (sometimes referred to as “junk” bonds), or, if unrated, determined to be of comparable credit quality by the Adviser. The Fund may invest up to 20% of its net assets in foreign securities. The Fund will only invest in U.S. dollar denominated securities. 
Under normal circumstances, the Fund will seek to maintain an average portfolio duration (price sensitivity to changes in interest rates) of plus or minus 2 years as compared to the Bloomberg U.S. Aggregate Bond Index. As of October 31, 2022, the duration of the Bloomberg U.S. Aggregate Bond Index was 6.09 years. Please refer to the Glossary of Investment Terms for additional information about duration. 
In selecting bond investments, the portfolio managers employ a combination of “bottom up” fundamental security selection with a “top down” thematic approach, focusing on positive social and environmental themes. To identify the universe of investible securities for the Fund, the portfolio managers first apply broad-based negative screens, which incorporate third-party inputs, to seek to avoid (i) securities of issuers that are non-compliant with the UN Global Compact, and/or (ii) securities of issuers that, in the determination of the Adviser, are significantly engaged in or derive more than de minimis revenue from (or securitized products the economic value of which is tied in more than de minimis fashion to), industries, activities or assets considered by the Adviser or the portfolio managers to have a negative impact on society or the environment. A current list of such activities, which may evolve over time, follows: 
 
 
alcohol; 
 
animal testing (cosmetics); 
 
chemicals of concern; 
 
contentious industries (limited to excluding companies that produce palm oil); 
 
controversial armaments; 
 
controversial fossil fuel extraction and refining; 
 
controversial fossil fuel power generation; 
 
fur; 
 
gambling; 
 
genetic engineering; 
 
pornography; 
 
tobacco production; and 
 
United Nations Global Compact violators. 
Thereafter, the portfolio managers seek to identify bonds that are aligned with positive environmental and social impact themes, which are informed by the United Nations Sustainable Development Goals (“UNSDGs”). The impact themes followed by the Fund, which may evolve over time, include the following: 
 
 
Transition to a Green Economy, including the development of clean energy and sustainable transportation and cities; 
 
Affordable Housing, including increased access to home ownership and benefiting low to moderate income borrowers; 
 
Economic and Community Development and Inclusion, which includes financial services and infrastructure that are integral in the development of a sustainable economy; 
 
Knowledge & Technology, and Innovation, which includes technological advancements that can enable a transition to more sustainable business practices for companies across industries, such as software and semiconductors and industry specific innovation; and 
 
Health & Well-Being, which includes increased access to healthcare, and innovation for medical treatment and health. 
Under normal circumstances, the Fund will generally sell or dispose of portfolio investments when, in the opinion of the Adviser, they (i) no longer present attractive investment opportunity (e.g., they have reached their expected value, or where better relative value exists elsewhere, or as the result of changing market conditions); and/or (ii) no longer meet the Fund’s ESG and/or sustainable criteria. Decisions with respect to the timing of such dispositions shall be made by the Fund’s portfolio managers taking into account the best interests of Fund shareholders. 
 
11½Janus Henderson Sustainable & Impact Core Bond ETF

The Fund may use derivatives, including, but not limited to, swaps (including interest-rate swaps, total rate of returns swaps and credit default swaps), swaptions, options, futures, and options on futures, which may be used for risk, duration and yield-curve management, or to enhance expected returns. Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, interest rates, currencies, or market indices. 
The Fund may invest in reverse-repurchase agreements and use the proceeds to invest in securities consistent with the Fund’s principal investment strategies. The Fund may enter into “to be announced” or “TBA” commitments when purchasing mortgage-backed securities or other securities. The Fund may also invest in floating rate obligations, such as collateralized loan obligations, floating rate senior secured syndicated bank loans, floating rate unsecured loans, and other floating rate bonds, loans and notes. The Fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale (these are known as “restricted securities”), which may include Rule 144A securities. 
The Fund may also invest in cash or cash equivalents such as commercial paper, repurchase agreements and other short-duration fixed-income securities. The Fund may invest its uninvested cash in affiliated or non-affiliated money market funds (or private funds operating as money market funds). Due to the nature of the securities in which the Fund may invest, as well as certain investment techniques utilized by the portfolio managers, it may have relatively high portfolio turnover compared to other funds. 
The portfolio managers do not apply the ESG factors noted above in managing the Fund’s cash and exposure to U.S. Treasuries and certain derivatives, such as credit default swaps on indices or derivatives used to manage interest rate risk. 
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, on a short-term or long-term basis, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination. 
 
PRINCIPAL INVESTMENT RISKS
The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. The principal risks associated with investing in the Fund are set forth below.
Fixed-Income Securities Risk.  The Fund invests in a variety of debt and other fixed-income securities that are generally subject to the following risks:
  
 
Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. The United States is currently experiencing a rising interest rate environment, which may increase the Fund’s exposure to risks associated with rising interest rates. Rising interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. 
 
 
Credit risk is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default. 
 
 
Prepayment risk is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential. 
 
 
Valuation risk is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security. 
 
 
Extension risk is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall. 
 
 
Liquidity risk is the risk that fixed-income securities may be difficult or impossible to sell at the time that the portfolio managers would like or at the price the portfolio managers believe the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). 
 
12½Janus Henderson Sustainable & Impact Core Bond ETF

Market Risk.  The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value (“NAV”) may decrease. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as terrorism, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics, including COVID-19) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money. 
Mortgage- and Asset-Backed Securities Risk.  Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Mortgage- and asset-backed securities tend to be more sensitive to changes in interest rates than other types of debt securities. These risks may reduce the Fund’s returns. In addition, investments in mortgage- and asset-backed securities, including those comprised of subprime mortgages, may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn. 
Corporate Bond Risk.  The investment return of corporate bonds reflects interest earned on the security and changes in the market value of the security. The market value of a corporate bond may be affected by changes in interest rates, the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the marketplace. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates. The market value of intermediate and longer-term corporate bonds is generally more sensitive to changes in interest rates than is the market value of shorter-term corporate bonds. Corporate bonds are also subject to the credit risk of the issuer, as the issuer of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument. 
U.S. Government Securities Risk.  Certain U.S. Government securities are not guaranteed or backed by the full faith and credit of the United States. For these securities, the Fund must look principally to the agency or instrumentality issuing or guaranteeing the securities for repayment and may not be able to assert a claim against the United States if the agency or instrumentality does not meet its commitment. Such securities may involve increased risk of loss of principal and interest compared to government debt securities that are backed by the full faith and credit of the United States. 
Sustainable Investment Risk.  The Fund follows a sustainable investment approach by investing in debt securities that are aligned with positive environmental and social impact themes and/or the debt of companies with business practices that the Adviser believes to be sustainable and/or demonstrate adherence to certain sustainable and/or ESG-related practices. Accordingly, the Fund may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector, which may make the Fund more vulnerable to unfavorable developments in a particular sector than funds that invest more broadly. Additionally, due to its exclusionary criteria, the Fund may not be invested in certain industries or sectors, and therefore may have lower performance than portfolios that do not apply similar criteria. In addition, because sustainable and ESG investing takes into consideration factors beyond traditional financial analysis, the investment opportunities for the Fund may be limited at times. Sustainability and ESG-related information provided by issuers and third parties, upon which the portfolio managers may rely, continues to develop, and may be incomplete, inaccurate, use different methodologies, or be applied differently across companies and industries. Further, the regulatory landscape for sustainable and ESG investing in the United States is still developing and future rules and regulations may require the Fund to modify or alter its investment process. Similarly, government policies incentivizing companies to engage in sustainable and ESG practices may fall out of favor, which could potentially limit the Fund’s investment universe. There is also a risk that the companies identified through the investment process may fail to adhere to sustainable and/or ESG-related business practices, which may result in the Fund selling a security when it might otherwise be disadvantageous to do so. 
Industry and Sector Risk.  Although the Fund does not concentrate its investments in specific industries or industry sectors, it emphasizes certain themes. As a result, at times, it may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector or that benefit from the same theme. Companies in the same industry or economic sector or that benefit from the same theme may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments than funds that invest more broadly. As the Fund’s portfolio becomes more concentrated, the Fund is less able to spread risk and potentially reduce the risk of loss and volatility. 
 
13½Janus Henderson Sustainable & Impact Core Bond ETF

High-Yield/High-Risk Bond Risk.  High-yield/high-risk bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value. 
Floating Rate Obligations Risk.  The Fund may invest in floating rate obligations that reset regularly, maintaining a fixed spread over a stated reference rate such as the London InterBank Offered Rate (“LIBOR”), the Secured Overnight Financing Rate (“SOFR”), or the Treasury bill rate. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Unexpected changes in the interest rates on floating rate obligations could result in lower income to the Fund. In addition, the secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations and that there may be restrictions on their transfer. As a result, the Fund may be unable to sell assignments or participations at the desired time or may be able to sell only at a price less than fair market value. 
Portfolio Management Risk.  The Fund is an actively managed investment portfolio and is therefore subject to the risk that the portfolio managers may not be successful in identifying investment opportunities that are aligned with the sustainable investment approach that the Fund employs. The Fund may underperform its benchmark index or other funds with similar investment objectives. 
Liquidity Risk. The Fund may invest in securities or instruments that do not trade actively or in large volumes and may make investments that are less liquid than other investments. Also, the Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions. Investments that are illiquid or that trade in lower volumes may be more difficult to value. When there is no willing buyer and investments cannot be readily sold at the desired time or price, the Fund may have to accept a lower price or may not be able to sell the security or instrument at all. Investments in foreign securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk than domestic securities. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). An inability to sell one or more portfolio positions can adversely affect the Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities. 
Derivatives Risk.  Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage because leverage can exaggerate the effect of any increase or decrease in the value of securities and other instruments held by the Fund. Derivatives also involve the risk that the counterparty to the derivative transaction will default on its payment obligations. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by the portfolio managers or if the cost of the derivative outweighs the benefit of the hedge. 
Restricted Securities Risk.  Investments in restricted securities, including securities issued under Regulation S and Rule 144A, could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Restricted securities may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available. 
Portfolio Turnover Risk.  Increased portfolio turnover may result in higher costs which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders. 
LIBOR Replacement Risk.  Certain debt securities, derivatives, or other financial instruments utilize the London InterBank Offered Rate (“LIBOR”) as a reference rate for various rate calculations. The U.K. Financial Conduct Authority has ceased to publish or maintain as representative many LIBOR settings, and will phase out certain other commonly-used U.S. dollar LIBOR settings as of June 30, 2023. The elimination of LIBOR or other reference rates and the transition process away from LIBOR could adversely impact (i) volatility and liquidity in markets that are tied to those reference rates, (ii) the market for, or value of, specific securities or payments linked to those reference rates, (iii) the availability or terms of borrowing or refinancing, or (iv) the effectiveness of hedging strategies. For these and other reasons, the elimination of LIBOR or other reference rates may adversely affect the Fund’s performance and/or NAV. Alternatives to LIBOR are established or in development in most major currencies including the Secured Overnight Financing Rate (“SOFR”) that is intended to replace the U.S. dollar LIBOR. 
 
14½Janus Henderson Sustainable & Impact Core Bond ETF

The effect of the discontinuation of LIBOR or other reference rates on the Fund will vary depending on, among other things (i) existing fallback or termination provisions in individual contracts and (ii) whether, how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new products and instruments. Accordingly, it is difficult to predict the full impact of the transition away from LIBOR or other reference rates on the Fund until new reference rates and fallbacks for both legacy and new products, instruments and contracts are commercially accepted. 
Leverage Risk.  Leverage can magnify the effect of any gains or losses, causing the Fund to be more volatile than if it had not been leveraged. In addition, the Fund’s assets that are used as collateral to secure short sale transactions may decrease in value while the short positions are outstanding, which may force the Fund to use its other assets to increase collateral. There is no assurance that a leveraging strategy will be successful. 
Foreign Exposure Risk.  Foreign markets, including emerging markets, can be more volatile than the U.S. market. As a result, the Fund’s returns and NAV may be affected by political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in foreign debt securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk and may be more sensitive to changes in interest rates than domestic securities. Additionally, investments in securities of foreign governments involve the risk that a foreign government may not be willing or able to pay interest or repay principal when due. The Fund’s investments in emerging market countries, if any, may involve risks greater than, or in addition to, the risks of investing in more developed countries. 
Reverse Repurchase Agreement Risk.  Reverse repurchase agreements are transactions in which the Fund sells a security and simultaneously commits to repurchase that security from the buyer, such as a bank or broker-dealer, at an agreed upon price on an agreed upon future date. The repurchase price consists of the sale price plus an incremental amount reflecting the interest cost to the Fund on the proceeds it has received from the initial sale. Reverse repurchase agreements involve the risk that the value of securities that the Fund is obligated to repurchase under the agreement may decline below the repurchase price. Additionally, such transactions are only advantageous if the interest cost to the Fund of the reverse repurchase transaction is less than the cost of obtaining the cash otherwise. Interest costs on the proceeds received in a reverse repurchase agreement may exceed the return received on the investments made by the Fund with those proceeds, resulting in reduced returns to shareholders. When the Fund enters into a reverse repurchase agreement, it is subject to the risk that the buyer (counterparty) may default on its obligations to the Fund. In the event of such a default, the Fund may experience delays, costs, and losses, all of which may reduce returns to shareholders. Investing reverse repurchase proceeds may also have a leveraging effect on the Fund’s holdings. The Fund’s use of leverage can magnify the effect of any gains or losses, causing the Fund to be more volatile than if it had not been leveraged. There is no assurance that any leveraging strategy used by the Fund will be successful. 
Smaller Sized Fund Risk.  Because the Fund has a small asset base, large inflows and outflows may have a disproportionate impact, negative or positive, on the Fund’s performance, which may be more volatile than that of a larger fund. If a smaller fund were to fail to attract sufficient assets to achieve or maintain economies of scale, performance may be negatively impacted, and any resulting liquidation could create negative transaction costs for the Fund and tax consequences for investors. 
TBA Commitments Risk.  Although TBA securities must meet industry-accepted “good delivery” standards, there can be no assurance that a security purchased on a forward commitment basis will ultimately be issued or delivered by the counterparty. If the counterparty to a transaction fails to deliver the securities, the Fund could suffer a loss. Because TBA commitments do not require the purchase and sale of identical securities, the characteristics of the security delivered to the Fund may be less favorable than the security delivered to the dealer. Accordingly, there is a risk that the security that the Fund buys will lose value between the purchase and settlement dates. 
Securities Lending Risk.  Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund lends its securities and is unable to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Any cash received as collateral for loaned securities will be invested in an affiliated cash management vehicle or time deposits. This investment is subject to market appreciation or depreciation and the Fund will bear any loss on the investment of its cash collateral. 
 
15½Janus Henderson Sustainable & Impact Core Bond ETF

Exchange Listing and Trading Issues Risk.  Although Fund shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”), there can be no assurance that an active trading market for such shares will develop or be maintained. The lack of an active market for Fund shares, as well as periods of high volatility, disruptions in the creation/redemption process, or factors affecting the liquidity of the underlying securities held by the Fund, may result in the Fund’s shares trading at a premium or discount to its NAV. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund shares inadvisable. In addition, trading is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the Fund’s listing will continue to be met or will remain unchanged. 
Fluctuation of NAV and Market Price Risk.  The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s securities holdings. The market prices of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s NAV and supply and demand of shares on the Exchange. Volatile market conditions, an absence of trading in shares of the Fund, or a high volume of trading in the Fund, may result in trading prices in the Fund’s shares that differ significantly from the Fund’s NAV. Additionally, during a “flash crash,” the market prices of the Fund’s shares may decline suddenly and significantly resulting in Fund shares trading at a substantial discount to NAV. Such a decline may not reflect the performance of the portfolio securities held by the Fund. Flash crashes may cause Authorized Participants and other market makers to limit or cease trading in the Fund’s shares for temporary or longer periods, which may result in an increase in the variance between market prices of the Fund’s shares and the Fund’s NAV. Shareholders could suffer significant losses to the extent that they sell shares at these temporarily low market prices. 
It cannot be predicted whether Fund shares will trade below, at or above the Fund’s NAV. Further, the securities held by the Fund may be traded in markets that close at a different time than the Exchange. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the Exchange is open but after the applicable market closing or fixing settlement times, bid-ask spreads and the resulting premium or discount to the Fund shares’ NAV is likely to widen. Similarly, the Exchange may be closed at times or days when markets for securities held by the Fund are open, which may increase bid-ask spreads and the resulting premium or discount to the Fund shares’ NAV when the Exchange re-opens. The Fund’s bid-ask spread and the resulting premium or discount to the Fund’s NAV may also be impacted by the liquidity of the underlying securities held by the Fund, particularly in instances of significant volatility of the underlying securities. 
Authorized Participant Risk.  The Fund may have a limited number of financial institutions that may act as Authorized Participants (“APs”). Only APs who have entered into agreements with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund. These APs have no obligation to submit creation or redemption orders and, as a result, there is no assurance that an active trading market for the Fund’s shares will be established or maintained. This risk may be heightened to the extent that the securities underlying the Fund are traded outside of a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be willing or able to do. Additionally, to the extent that those APs exit the business or are unable to process creation and/or redemption orders, and no other AP is able to step forward to create and redeem in either of these cases, shares may trade like closed-end fund shares at a premium or a discount to NAV and possibly face delisting. 
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.

MANAGEMENT
Investment Adviser: Janus Henderson Investors US LLC
Portfolio Managers: Nick Childs, CFA, is Co-Portfolio Manager of the Fund, which he has co-managed since inception. Greg Wilensky, CFA, is Co-Portfolio Manager of the Fund, which he has co-managed since inception.
 
PURCHASE AND SALE OF FUND SHARES
The Fund is an actively-managed Exchange-Traded Fund (“ETF”). Unlike shares of traditional mutual funds, shares of the Fund are not individually redeemable and may only be purchased or redeemed directly from the Fund at NAV in large increments called “Creation Units” through APs and the Adviser may modify the Creation Unit size with prior notification to the Fund’s APs. See the ETF portion of the Janus Henderson website for the Fund’s current Creation Unit size. Creation Unit transactions are conducted in exchange for the deposit or delivery of a designated portfolio of in-kind securities with a cash balancing amount and/or all cash. Except when aggregated in Creation Units, Fund shares are not redeemable securities of the Fund. Shares of the Fund are listed and trade on the Exchange, and individual investors can purchase or sell shares in much smaller increments for cash in the secondary market through a broker-dealer. These transactions, which do not involve the Fund, are made at market prices that may vary throughout the day and differ from the Fund’s NAV. As a result, you may pay more than
 
17½Janus Henderson Sustainable & Impact Core Bond ETF

NAV (at a premium) when you purchase shares, and receive less than NAV (at a discount) when you sell shares, in the secondary market.
Investors purchasing or selling shares in the secondary market may also incur additional costs, including brokerage commissions and an investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”). Historical information regarding the Fund’s bid/ask spread can be accessed on the Fund’s website at janushenderson.com/performance by selecting the Fund.
 
TAX INFORMATION
The Fund’s distributions are generally taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed at ordinary income tax rates upon withdrawal of your investment from such account). A sale of Fund shares may result in a capital gain or loss.
 
PAYMENTS TO BROKER‑DEALERS AND OTHER FINANCIAL INTERMEDIARIES
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Adviser and/or its affiliates may pay broker-dealers or intermediaries for the sale and/or maintenance of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

ADDITIONAL INFORMATION ABOUT THE FUNDS
 
 
 
FEES AND EXPENSES
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended October 31, 2022.
 
 
“Annual Fund Operating Expenses” are paid out of a Fund’s assets. You do not pay these fees directly but, as the Example in each Fund Summary shows, these costs are borne indirectly by all shareholders.
 
 
The “Management Fee” is the rate paid by each Fund to the Adviser for providing certain services. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
 
 
“Other Expenses”
 
  °  
include acquired fund fees and expenses, which are indirect expenses a Fund may incur as a result of investing in shares of an underlying fund to the extent such expenses are less than 0.01%. “Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds (“ETFs”)) in which a fund invests or has invested during the period. Such amounts are less than 0.01%.
 
ADDITIONAL INVESTMENT STRATEGIES AND GENERAL PORTFOLIO POLICIES
The Funds are actively managed ETFs and, thus, do not seek to replicate the performance of a specified index. Accordingly, the portfolio managers have discretion on a daily basis to manage the Funds’ portfolios in accordance with each Fund’s investment objective.
The Funds’ Board of Trustees (“Trustees”) may change each Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. A Fund will notify you in writing at least 60 days or as soon as reasonably practicable before making any such change it considers material. If there is a material change to a Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that a Fund will achieve its investment objective.
On each business day before commencement of trading in shares on the Exchange, each Fund will disclose on janushenderson.com/info the identities and quantities of each portfolio position held by the Fund that will form the basis for the Fund’s next calculation of the NAV per share. A description of each Fund’s policies and procedures with respect to the disclosure of the Fund’s portfolio holdings is available in the Fund’s SAI. Information about the premiums and discounts at which each Fund’s shares have traded is available at janushenderson.com/performance by selecting the Fund for additional details.
Unless otherwise stated, the following additional investment strategies and general policies apply to each Fund and provide further information including, but not limited to, the types of securities the Fund may invest in when implementing its investment objective. Some of these strategies and policies may be part of a principal strategy. Other strategies and policies may be utilized to a lesser extent. Except for each Fund’s policies with respect to investments in illiquid investments, borrowing and derivatives use, the percentage limitations included in these policies and elsewhere in this Prospectus and/or the SAI normally apply only at the time of purchase of a security. So, for example, if a Fund exceeds a limit, other than illiquid investments, borrowing and derivatives use, as a result of market fluctuations or the sale of other securities, it will not be required to dispose of any securities. The “Glossary of Investment Terms” includes descriptions of investment terms used throughout the Prospectus.
Each Fund may borrow to the extent permitted by the Investment Company Act of 1940, as amended (the “1940 Act”). At times, a Fund may be required to segregate or earmark certain assets determined to be liquid by the Adviser to cover borrowings. For temporary liquidity and cash management purposes, the Funds may invest in other ETFs that provide exposure that is consistent with each Fund’s respective investment objective.
Security Selection
In selecting investments, Janus Henderson Sustainable Corporate Bond ETF’s and Janus Henderson Sustainable & Impact Core Bond ETF’s portfolio managers combine a “bottom up” fundamental security selection with a “top down” thematic approach. In addition to sustainable and ESG factors, the portfolio managers for each Fund will consider company, industry and sector fundamentals, such as free cash flow generation, profitability and cyclicality, as well as credit quality and capital structure
 
19½Janus Detroit Street Trust

factors, such as a company’s outstanding debt, stability of cash flows and balance sheet. Under normal circumstances, the Funds will generally sell or dispose of their portfolio investments when, in the opinion of the Adviser, they (i) no longer present attractive investment opportunity (e.g., they have reached their expected value, or where better relative value exists elsewhere, or as the result of changing market conditions); and/or (ii) no longer meet the Fund’s respective ESG and/or sustainable criteria. Decisions with respect to the timing of such dispositions shall be made by each Fund’s portfolio managers taking into account the best interests of Fund shareholders.
Asset-Backed Securities
The Funds may invest in asset-backed securities. Asset-backed securities are collateralized by pools of obligations or assets. Most asset-backed securities involve pools of consumer or commercial debts with maturities less than ten years. However, almost any type of asset may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes, or pass-through certificates and may be structured as floaters, inverse floaters, interest-only and principal-only obligations. Similar to mortgage-backed securities, payments on asset-backed securities include both interest and a partial payment of principal. The value of the Fund’s investments in asset-backed securities may be adversely affected by changes in interest rates, factors concerning the interests in and structure of the issuer or originator of the receivables, the creditworthiness of the entities that provide any supporting letters of credit, surety bonds, or other credit or liquidity enhancements, and/or the market’s assessment of the quality of the underlying assets. Generally, the originating bank or credit provider is neither the obligor nor the guarantor of the security, and interest and principal payments ultimately depend upon payment of the underlying loans by individuals. The Funds could incur a loss if the underlying loans are not paid. In addition, most asset-backed securities are subject to prepayment risk in a declining interest rate environment. Prepayment risk is the risk that during periods of falling interest rates, certain fixed-income securities with higher interest rates, such as mortgage- and asset-backed securities, may be prepaid by their issuers thereby reducing the amount of interest payments. The impact of prepayments on the value of asset-backed securities may be difficult to predict and may result in greater volatility. Rising interest rates tend to extend the duration of asset-backed securities, making them more volatile and sensitive to changing interest rates. Janus Henderson Sustainable Corporate Bond ETF may invest up to 5% of its assets in asset-backed securities.
Cash Position
The Funds may not always stay fully invested. For example, when the portfolio managers believe that market conditions are unfavorable for investing, or when they are otherwise unable to locate attractive investment opportunities, a Fund’s cash or similar investments, such as commercial paper, repurchase agreements and other short-duration fixed-income securities, and/or affiliated or non-affiliated money market funds (or unregistered cash management pooled investment vehicles that operate as money market funds), may increase. When a Fund’s investments in cash or similar investments increase, it may not participate in market advances or declines to the same extent that it would if the Fund remained more fully invested. To the extent a Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.
In addition, a Fund may temporarily increase its cash position under certain unusual circumstances, such as to protect its assets or maintain liquidity in certain circumstances to meet unusually large redemptions. A Fund’s cash position may also increase temporarily due to unusually large cash inflows. Under unusual circumstances such as these, a Fund may invest up to 100% of its assets in cash or similar investments. In this case, a Fund may take positions that are inconsistent with its investment policies. As a result, a Fund may not achieve its investment objective.
Credit Risk Transfer Securities
The Funds may invest in credit risk transfer securities (“CRTs”). CRTs are unguaranteed and unsecured debt securities that are commonly issued by a government sponsored entity. CRTs are not directly linked to or backed by the underlying mortgage loans, so investors have no direct recourse to the underlying mortgage loans. In addition, some or all of the mortgage default risk associated with the underlying mortgage loans is transferred to the noteholder. Therefore, a Fund could lose all or part of its investments in CRTs securities in the event of a default by the underlying mortgages.
Corporate Bonds
Corporate bonds are debt obligations issued by corporations, institutions and other business entities. Typically, the debt is issued for the purpose of borrowing money, often to help the corporation develop a new product or service, to expand into a new market, or to buy another company. Bondholders, as creditors, have a prior legal claim over common and preferred stockholders as to both income and assets of the corporation for the principal and interest due them and may have a prior claim
 
20½Janus Detroit Street Trust

over other creditors if liens or mortgages are involved. Interest on corporate bonds may be fixed or floating, or the bonds may be zero coupons. Interest on corporate bonds is typically paid semi-annually and is fully taxable to the bondholder.
Corporate bonds are subject to interest rate risk. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates and may also be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the marketplace. Corporate bonds usually yield more than government or agency bonds due to the presence of credit risk. Corporate bonds are also subject to credit risk. As with other types of bonds, the issuer promises to repay the principal on a specific date and to make interest payments in the meantime. The amount of interest offered depends both on market conditions and on the financial health of the corporation issuing the bonds; a company whose credit rating is not strong will have to offer a higher interest rate to obtain buyers for its bonds. There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument. The market value of a corporate bond may also be affected by factors directly related to the issuer, such as investors’ perceptions of the creditworthiness of the issuer, the issuer’s financial performance, perceptions of the issuer in the market place, performance of management of the issuer, the issuer’s capital structure and use of financial leverage and demand for the issuer’s goods and services. Corporate bonds of below investment grade quality are often high risk and have speculative characteristics and may be particularly susceptible to adverse issuer-specific developments.
Collateralized Loan Obligations
The Funds may invest in CLOs. A CLO is a type of structured credit, which is a sector of the fixed income market that also includes asset-backed and mortgage-backed securities. Typically organized as a trust or other special purpose vehicle, a CLO issues debt and equity interests and uses the proceeds from this issuance to acquire a portfolio of bank loans made primarily to businesses that are rated below investment grade. The underlying loans in which a CLO may invest may be issued or offered as “covenant lite” loans, which have few or no financial maintenance covenants. The underlying loans are generally senior-secured/first-priority loans; however, the CLO may also include an allowance for second-lien and/or unsecured debt. Additionally, the underlying loans may include domestic and foreign senior secured loans, senior unsecured loans and subordinate corporate loans, some of which may individually be below investment grade or the equivalent if unrated. The portfolio of underlying loans is actively managed by the CLO manager for a fixed period of time (“reinvestment period”). During the reinvestment period, the CLO manager may buy and sell individual loans to create trading gains or mitigate loses. The CLO portfolio will generally be required to adhere to certain diversification rules established by the CLO issuer to mitigate against the risk of concentrated defaults within a given industry or sector. After a specified period of time, the majority owner of equity interests in the CLO may seek to call the CLO’s outstanding debt or refinance its position. If not called or refinanced, when the reinvestment period ends, the CLO uses cash flows from the underlying loans to pay down the outstanding debt tranches and wind up the CLO’s operations.
Interests in the CLOs are divided into two or more separate debt and equity tranches, each with a different credit rating and risk/return profile based upon its priority of claim on the cash flows produced by the underlying loan pool. Tranches are categorized as senior, mezzanine and subordinated/equity, according to their degree of credit risk. If there are defaults or the CLO’s collateral otherwise underperforms, scheduled payments to senior tranches take precedence over those of mezzanine tranches, and scheduled payments to mezzanine tranches take precedence over those to subordinated/equity tranches. The riskiest portion is the “Equity” tranche, which bears the bulk of defaults from the loans in the trust and serves to protect the other, more senior tranches from default in all but the most severe circumstances. Senior and mezzanine tranches are typically rated, with the former receiving ratings of A to AAA/Aaa and the latter receiving ratings of B to BBB/Baa. The ratings reflect both the credit quality of underlying collateral as well as how much protection a given tranche is afforded by tranches that are subordinate to it. Normally, CLOs are privately offered and sold, and thus are not registered under the securities laws. CLOs are typically floating-rate debt instruments; however, in some cases, certain CLOs may pay a fixed-rate.
Emerging Markets
Within the parameters of its specific investment policies, each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries include, but are not limited to, countries included in the MSCI Emerging Markets IndexSM. Janus Henderson Sustainable Corporate Bond ETF may invest up to 10% of its assets in emerging market securities. Janus Henderson Sustainable & Impact Core Bond ETF may invest up to 5% of its assets in U.S. dollar denominated emerging market securities.
 
21½Janus Detroit Street Trust

Exchange-Traded Funds
Each Fund may invest in ETFs, including affiliated ETFs. ETFs are typically open-end investment companies that are traded on a national securities exchange. ETFs typically incur fees, such as investment advisory fees and other operating expenses that are separate from those of each Fund, which will be indirectly paid by each Fund. As a result, the cost of investing in a Fund may be higher than the cost of investing directly in underlying ETFs and may be higher than other ETFs or mutual funds that invest directly in stocks and bonds. Since ETFs are traded on an exchange at market prices that may vary from the NAV of their underlying investments, there may be times when ETFs trade at a premium or discount. In the case of affiliated ETFs, unless waived, the Adviser will earn fees both from such Fund and from the underlying ETF, with respect to assets of the Fund invested in the underlying ETF. Each Fund is also subject to the risks associated with the securities in which the ETF invests.
Foreign Securities
Foreign securities are generally selected on a security-by-security basis without regard to any predetermined allocation among countries or geographic regions. However, certain factors, such as expected levels of inflation, government policies influencing business conditions, the outlook for currency relationships, and prospects for economic growth among countries, regions, or geographic areas, may warrant greater consideration in selecting foreign securities. Janus Henderson Sustainable Corporate Bond ETF may invest a maximum of 10% in emerging market securities and a maximum of 5% in non-U.S. dollar denominated securities. Janus Henderson Sustainable & Impact Core Bond ETF may invest up to 20% of its net assets in U.S. dollar denominated foreign securities, including up to 5% in emerging markets.
High-Yield/High-Risk Bonds
Within the parameters of its specific investment policies, a Fund may invest in bonds that are rated below investment grade (also known as a “junk” bond), such as BB+ or lower by Standard & Poor’s Ratings Services (“Standard & Poor’s”) and Fitch, Inc. (“Fitch”), or Ba1 or lower by Moody’s Investors Service, Inc. (“Moody’s”), or is an unrated bond of similar quality. Lower rated bonds have a higher credit risk than higher quality bonds. A Fund may also invest in unrated bonds of foreign and domestic issuers. Janus Henderson Sustainable Corporate Bond ETF may invest up to a maximum of 15% of its net assets in high yield securities, with a minimum rating of B-. Janus Henderson Sustainable & Impact Core Bond ETF may invest up to a maximum of 5% of its net assets in high yield securities.
Illiquid Investments
A Fund will not 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. An illiquid investment is any investment that a 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.
Interest Rate Futures Contracts
Interest rate futures contracts, including futures contracts on U.S. Treasuries, Eurodollars and other futures contracts that provide interest rate exposure, are typically exchange-traded, are typically used to obtain interest rate exposure in order to manage duration and hedge interest rate risk. An interest rate futures contract is a bilateral agreement where one party agrees to accept and the other party agrees to make delivery of a specified security, as called for in the agreement at a specified date and at an agreed upon price. Generally, Treasury interest rate futures contracts are closed out or rolled over prior to their expiration date.
Loans
Janus Henderson Sustainable & Impact Core Bond ETF may invest in various commercial loans, including bank loans, bridge loans, mezzanine loans, and other fixed and floating rate loans. Janus Henderson Sustainable Corporate Bond ETF may invest in bank loans. These loans may be acquired through loan participations and assignments or on a when-issued basis.
Bank Loans. Bank loans are obligations of companies or other entities entered into in connection with recapitalizations, acquisitions, and refinancings. A Fund’s investments in bank loans are generally acquired as a participation interest in, or assignment of, loans originated by a lender or other financial institution. These investments may include institutionally-traded floating and fixed-rate debt securities.
Bridge Loans. Bridge loans are short-term loan arrangements typically made by a borrower in anticipation of receiving intermediate-term or long-term permanent financing. Most bridge loans are structured as floating-rate debt with step-up provisions under which the interest rate on the bridge loan increases the longer the loan remains outstanding. In addition, bridge loans commonly contain a conversion feature that allows the bridge loan investor to convert its loan interest to senior exchange notes if the loan has not been prepaid in full on or prior to its maturity date. Bridge loans typically are structured as senior loans, but may be structured as junior loans.
 
22½Janus Detroit Street Trust

Mezzanine Loans. Mezzanine loans are a hybrid of debt and equity financing that is typically used to fund the expansion of existing companies. A mezzanine loan is composed of debt capital that gives the lender the right to convert to an ownership or equity interest in the company if the loan is not paid back in time and in full. Mezzanine loans typically are the most subordinated debt obligation in an issuer’s capital structure.
Mortgage-Backed Securities
Janus Henderson Sustainable & Impact Core Bond ETF may invest in mortgage-backed securities. Mortgage-backed securities represent an ownership interest in a pool of mortgage loans used to finance purchases of real estate. The mortgage loans that comprise a pool normally have similar interest rates (fixed or variable), maturities and other terms. Pools of mortgages financing residential home purchases are referred to as residential mortgage-backed securities (“RMBS”), while pools of mortgages financing commercial buildings, multi-family properties and other real estate are referred to as commercial mortgage-backed securities (“CMBS”). Mortgage-backed securities may be issued or guaranteed by the U.S. government, its agencies or instrumentalities (“agency mortgage-backed securities”), or may be issued or guaranteed by private entities such as commercial banks, savings and loan institutions or mortgage bankers (“privately issued mortgage-backed securities”).
The Fund may invest in fixed or variable rate agency mortgage-backed securities issued by the Government National Mortgage Association (“Ginnie Mae”), the Federal National Mortgage Association (“Fannie Mae”), the Federal Home Loan Mortgage Corporation (“Freddie Mac”), or other governmental or government-related entities. Ginnie Mae’s guarantees are backed by the full faith and credit of the U.S. Government. Fannie Maes and Freddie Macs are not backed by the full faith and credit of the U.S. Government. The U.S. Department of the Treasury, however, has the authority to support Fannie Mae and Freddie Mac by purchasing limited amounts of their respective obligations.
Unlike traditional debt instruments, payments on mortgage-backed securities include both interest and a partial payment of principal. Prepayment of the principal of underlying loans at a faster pace than expected is known as “prepayment risk,” and may shorten the effective maturities of these securities. This may result in the Fund having to reinvest proceeds at a lower interest rate. Mortgage-backed securities tend to be more sensitive to changes in interest rates than other types of debt securities. In addition to prepayment risk, investments in privately-issued mortgage-backed securities may be subject to a higher degree of credit risk, valuation risk, and liquidity risk than other mortgage-backed securities. Mortgage-backed securities are also subject to extension risk. Extension risk is the risk that borrowers may pay off their debt obligations more slowly in times of rising interest rates. The risks associated with CMBS reflect the risks of investing in the commercial real estate securing the underlying mortgage loans and are therefore different from the risks of other types of mortgage-backed securities.
Mortgage Dollar Rolls
Janus Henderson Sustainable & Impact Core Bond ETF utilizes “mortgage dollar rolls,” which are similar to reverse repurchase agreements in certain respects. In a “mortgage dollar roll” transaction, the Fund sells a mortgage-related security (such as a Ginnie Mae security) to a dealer and simultaneously agrees to repurchase a similar security (but not the same security) in the future at a predetermined price. A “dollar roll” can be viewed, like a reverse repurchase agreement, as a collateralized borrowing in which the Fund pledges a mortgage-related security to a dealer to obtain cash. Successful use of mortgage dollar rolls depends on the Fund’s ability to predict interest rates and mortgage payments. Dollar roll transactions involve the risk that the market value of the securities the Fund is required to purchase may decline below the agreed upon repurchase price. The use of mortgage dollar rolls often results in higher portfolio turnover.
Options on Futures Contracts
An option on a futures contract gives the buyer the right, but not the obligation, to buy or sell a futures contract at a specified price on or before a specified date. Futures contracts and options on futures are standardized and traded on designated exchanges.
Options on Securities Indices
The Funds may purchase and write put and call options on securities indices. A put option on an index gives the holder the right to receive, upon exercise of the option, an amount of cash if the closing level of the underlying index is less than the exercise price of the option. A call option on an index gives the holder the right to receive, upon exercise of the option, an amount of cash if the closing level of the underlying index is greater than the exercise price of the option. This amount of cash is equal to the difference between the closing price of the index and the exercise price of the option, expressed in dollars multiplied by a specified number. Thus, unlike options on individual securities, all settlements are in cash, and gain or loss depends on price movements in the particular market represented by the index generally, rather than the price movements in individual securities. The premium paid to the writer is consideration for undertaking the obligations under the option contract.
 
23½Janus Detroit Street Trust

Options on Swap Contracts
The Funds may enter into options on swap agreements, commonly referred to as “swaptions.” A swaption is a contract that gives a purchaser the right, but not the obligation, to enter into a new swap agreement or to shorten, extend, cancel, or otherwise modify an existing swap agreement, at some designated future time on specified terms. Swaptions can be used for a variety of purposes, including to manage a Fund’s overall exposure to changes in interest rates and credit quality; as an efficient means of adjusting a Fund’s exposure to certain markets; in an effort to enhance income or total return or protect the value of portfolio securities; to serve as a cash management tool; and to adjust portfolio duration or credit risk.
Pass-Through Securities
Pass-through securities (such as mortgage- and asset-backed securities) are debt securities that normally give the issuer an option to pay cash at a coupon payment date or give the holder of the security a similar bond with the same coupon rate and a face value equal to the amount of the coupon payment that would have been made. In the pass-through structure, principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis. These securities involve prepayment risk. In that case, the Funds may have to reinvest the proceeds from the securities at a lower rate. Potential market gains on a security subject to prepayment risk may be more limited than potential market gains on a comparable security that is not subject to prepayment risk.
Portfolio Turnover
Portfolio turnover rates are generally not a factor in making buy and sell decisions. Changes may be made to a Fund’s portfolio, consistent with the Fund’s investment objective and policies, when the portfolio managers believe such changes are in the best interests of the Fund and its shareholders. Short-term transactions may result from the purchase of a security in anticipation of relatively short-term gains, liquidity needs, securities having reached a price or yield objective, changes in interest rates or the credit standing of an issuer, or by reason of economic or other developments not foreseen at the time of the initial investment decision. A Fund may also sell one security and simultaneously purchase the same or a comparable security to take advantage of short-term differentials in bond yields or securities prices. Portfolio turnover is affected by market conditions, changes in the size of a Fund (including due to purchases and redemptions of Creation Units), the nature of a Fund’s investments, and the investment style of the portfolio managers.
Increased portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on a Fund’s performance. The “Financial Highlights” section of this Prospectus shows the Funds’ historical turnover rates.
Preferred Stock
A preferred stock (or preferred security) represents an ownership interest in a company, but pays dividends at a specific rate and has priority over common stock in payment of dividends and liquidation claims. Preferred stock dividends are generally cumulative, noncumulative, or participating. “Cumulative” dividend provisions require all or a portion of prior unpaid dividends to be paid before dividends can be paid to the issuer’s common stock. “Participating” preferred stock may be entitled to a dividend exceeding the stated dividend in certain cases. Like debt securities, the value of a preferred stock often fluctuates more in response to changes in interest rates and the creditworthiness of the issuer, rather than in response to changes in the issuer’s profitability and business prospects. Preferred stock is subject to similar risks as common stock and debt securities.
Securities Lending
A Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions on a short-term or long-term basis, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination. When a Fund lends its securities, it receives collateral (including cash collateral), at least equal to the value of securities loaned. A Fund may earn income by investing this collateral in one or more affiliated or non-affiliated cash management vehicles or in time deposits. It is also possible that, due to a decline in the value of a cash management vehicle in which collateral is invested, a Fund may lose money. Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If a Fund lends its securities and is unable to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to a Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Any cash received as collateral for loaned securities will be invested in an affiliated cash management vehicle or time deposits. This investment is subject to market appreciation or depreciation and a Fund will bear any loss on the investment of its cash collateral. In certain circumstances, individual loan transactions could yield negative returns. The Adviser intends to manage a portion of the cash collateral in an affiliated cash management vehicle and will receive an investment advisory fee for managing such assets.
 
24½Janus Detroit Street Trust

Short Positions
The Funds may invest in short positions using interest rate futures, swaps, forward contracts, options and also through the short sale of portfolio securities, including ETFs. A short sale is generally a transaction in which a Fund sells a security it does not own or have the right to acquire (or that it owns but does not wish to deliver) in anticipation that the market price of that security will decline. To complete the transaction, a Fund must borrow the security to make delivery to the buyer. A Fund is then obligated to replace the security borrowed by purchasing the security at the market price at the time of replacement. A short sale is subject to the risk that if the price of the security sold short increases in value, a Fund will incur a loss because it will have to replace the security sold short by purchasing it at a higher price. In addition, a Fund may not always be able to close out a short position at a particular time or at an acceptable price. A lender may request, or market conditions may dictate, that the securities sold short be returned to the lender on short notice, and a Fund may have to buy the securities sold short at an unfavorable price. If this occurs at a time that other short sellers of the same security also want to close out their positions, it is more likely that a Fund will have to cover its short sale at an unfavorable price and potentially reduce or eliminate any gain, or cause a loss, as a result of the short sale. Because there is no upper limit to the price a borrowed security may reach prior to closing a short position, a Fund’s losses are potentially unlimited in a short sale transaction. A Fund’s gains and losses will also be decreased or increased, as the case may be, by the amount of any dividends, interest, or expenses, including transaction costs and borrowing fees, the Fund may be required to pay in connection with a short sale. Such payments may result in a Fund having higher expenses than a fund that does not engage in short sales and may negatively affect the Fund’s performance.
A Fund may enter into a derivatives transaction to obtain short investment exposure to an underlying reference asset. If the value of the underlying reference asset on which a Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes a Fund to credit risk, counterparty risk, and leverage risk.
Special Situations
Janus Henderson Sustainable & Impact Core Bond ETF may invest in companies that demonstrate special situations or turnarounds, meaning companies that have experienced significant business problems but are believed to have favorable prospects for recovery. For example, a special situation or turnaround may arise when, in the opinion of the Fund’s portfolio managers, the securities of a particular issuer will be recognized as undervalued by the market and appreciate in value due to a specific development with respect to that issuer. Special situations may include significant changes in a company’s allocation of its existing capital, a restructuring of assets, or a redirection of free cash flow. For example, issuers undergoing significant capital changes may include companies involved in spin-offs, sales of divisions, mergers or acquisitions, companies involved in bankruptcy proceedings, or companies initiating large changes in their debt to equity ratio. Companies that are redirecting cash flows may be reducing debt, repurchasing shares, or paying dividends. Special situations may also result from: (i) significant changes in industry structure through regulatory developments or shifts in competition; (ii) a new or improved product, service, operation, or technological advance; (iii) changes in senior management or other extraordinary corporate event; (iv) differences in market supply of and demand for the security; or (v) significant changes in cost structure. Investments in “special situations” companies can present greater risks than investments in companies not experiencing special situations, and the Fund’s performance could be adversely impacted if the securities selected decline in value or fail to appreciate in value.
Sustainable and Impact Investments
For purposes of implementing the Funds’ respective investment strategies, sustainable and impact investments are those determined by the Adviser to be aligned with certain positive social and environmental and impact themes.
 
 
The Funds seek to avoid securities of issuers that are non-compliant with the UN Global Compact.
 
 
To identify the universe of investible securities for the Funds, the portfolio managers first apply broad-based negative screens, which incorporate third-party inputs, to seek to avoid securities of issuers that, in the determination of the Adviser, are significantly engaged in or derive more than de minimis revenue from (generally no more than 5-10%), or securitized products the economic value of which is tied in more than de minimis fashion to, industries, activities or assets considered by the portfolio managers to have a negative impact on society or the environment.
 
25½Janus Detroit Street Trust

In screening such investments, there may be instances where the de minimis limits cannot be expressed quantitatively, in which case the portfolio managers apply a qualitative assessment of an issuer. Among other things, the qualitative assessment looks at the extent to which an “avoided” activity is part of a company’s business, whether a company is taking action to address and improve upon such activity, and may consider certain issuers, industries or sectors that are in the process of transitioning to sustainable business practices, in which case a threshold of greater than 5-10% may initially be applied.
A current list of such activities, which may evolve over time follows:
 
 
alcohol;
 
animal testing (cosmetics);
 
chemicals of concern;
 
contentious industries (limited to excluding companies that produce palm oil);
 
controversial armaments;
 
controversial fossil fuel extraction and refining;
 
controversial fossil fuel power generation;
 
fur;
 
gambling;
 
genetic engineering;
 
pornography;
 
tobacco production; and
 
United Nations Global Compact violators.
From the universe of eligible securities, each Fund’s portfolio managers will identify sustainable investments through consideration of various environmental, social and/or governance factors, and in light of fundamental fixed income investment criteria.
Janus Henderson Sustainable Corporate Bond ETF will seek to invest in securities of issuers with sustainable business practices. The portfolio managers seek to select securities that align with certain positive social and environmental themes, which are informed by United Nations Sustainable Development Goals (“UNSDGs”). These themes of focus, which may evolve over time and/or incorporate other themes aligned with UNSDGs, include the following:
 
 
Transition to a Green Economy, including the development of clean energy and sustainable transportation and cities;
 
 
Economic and Community Development and Inclusion, which includes financial services and infrastructure that are integral in the development of a sustainable economy;
 
 
Knowledge & Technology, and Innovation, which includes technological advancements that can enable a transition to more sustainable business practices for companies across industries, such as software and semiconductors and industry specific innovation; and
 
 
Health & Well-Being, which includes increased access to healthcare, and innovation for medical treatment and health.
Janus Henderson Sustainable & Impact Core Bond ETF will seek to invest primarily in bonds that are aligned with positive environmental and social impact themes which are informed by UNSDGs. The impact themes followed by the Fund, which may evolve over time, include the following:
 
 
Transition to a Green Economy, including the development of clean energy and sustainable transportation and cities;
 
 
Affordable Housing, including increased access to home ownership and benefiting low to moderate income borrowers;
 
 
Economic and Community Development and Inclusion, which includes financial services and infrastructure that are integral in the development of a sustainable economy;
 
 
Knowledge & Technology, and Innovation, which includes technological advancements that can enable a transition to more sustainable business practices for companies across industries, such as software and semiconductors and industry specific innovation; and
 
 
Health & Well-Being, which includes increased access to healthcare, and innovation for medical treatment and health.
The Fund’s investments will first be analyzed and selected using an integrated ESG approach and will be subject to the negative ESG screens discussed above, with the exception of investments deemed “out-of-scope.” Next, certain of these investments will
 
26½Janus Detroit Street Trust

be further characterized by one of the following two categories: (i) impact investments, which will be aligned with one or more of the measurable impact themes; and (ii) sustainable investments, which will be aligned with one or more impact themes, and identified and assessed on a qualitative basis. “Out-of-scope” investments that are not part of this process include cash instruments, certain derivatives and U.S. Treasuries.
The Funds’ investments may, but are not required to, include called “labeled bonds”, which include debt where the proceeds have been specifically earmarked for ESG-themed purposes (“Use of Proceeds” bonds), or the returns are specifically tied to defined sustainable or environmental key performance indicators (“KPI-linked” bonds). As the labeled bond market is relatively new and continues to evolve, the type and structure of such investments, as well as the criteria used to define them, may change in the future. Labeled bonds may be structured in various ways including, but not limited to:
 
 
Use of Proceeds – Proceeds from the issuance of the bonds (or other revenue streams associated with the bonds) are earmarked for green, social or other sustainable projects.
 
 
Project Bond – Proceeds from the issuance of the bonds are ring-fenced for a specific underlying green, social or other sustainable projects.
 
 
Securitization Bond – Proceeds from the issuance of the bonds are used to refinance portfolios of green projects or proceeds are earmarked for green, social or other sustainable projects.
 
 
Covered Bond – Proceeds from the issuance of the bonds are earmarked for eligible green, social or other sustainable projects included in the covered pool.
 
 
Loan Interests – Proceeds from the loan are earmarked for eligible green, social or other sustainable projects or secured on eligible assets.
 
 
Other debt instruments (e.g., convertible bonds or notes or commercial paper) – where proceeds are earmarked for eligible green, social or other sustainable projects.
Green Bonds are bonds, notes and debentures the proceeds of which are used to finance projects which the Adviser believes will have a positive environmental impact. Green bonds may be issued by corporations, banks, supranational entities, development banks, agencies, regions and governments, among others. Certain green bonds may be dependent on government incentives and subsidies and lack of political support for the financing of projects with a positive environmental impact could negatively impact the performance of the bonds, and in turn, the performance of a Fund.
Social Bonds are bonds, notes and debentures the proceeds of which are used to finance projects which the Adviser believes will have a positive social impact. Social Bonds are usually issued to finance specific projects intended to assist with positive developments in education, health and social services, affordable housing, economic opportunity and community development, environment or energy-related products and services, and connectivity (e.g., proliferation or improvement of broadband internet or mass transit infrastructure). These bonds may also be geared towards development of opportunity for target populations, including immigrants, the unemployed, the food insecure, persons of color and/or women or sexual and gender minorities, and persons with disabilities.
Sustainability Bonds are bonds, notes and debentures the proceeds of which will be exclusively applied to finance or refinance a combination of both environmental and social projects, with recognition that certain social projects may also have environmental co-benefits, and vice versa.
Sustainability-linked Bonds are bonds, notes and debentures the performance of which is structurally tied to the achievement of predefined environmental or social objectives. The economic value of these bonds (typically through an increase or decrease to the bond’s coupon rate) will be impacted by the issuer’s progress (or lack of progress) towards achievement of these stated goals, through monitoring of selected KPIs relative to performance targets.
Swap Agreements
The Funds may utilize swap agreements such as credit default, interest rate, and total return swaps, as a means to hedge its portfolio against adverse movements in securities prices, the rate of inflation, or interest rates. Swap agreements are two-party contracts to exchange one set of cash flows for another. Swap agreements entail the risk that a party will default on its payment obligations to a Fund. If the other party to a swap defaults, a Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. If a Fund utilizes a swap at the wrong time or judges market conditions
 
27½Janus Detroit Street Trust

incorrectly, the swap may result in a loss to the Fund and reduce the Fund’s total return. Various types of swaps such as credit default, interest rate, and total return swaps are described in this Prospectus and/or in the “Glossary of Investment Terms.”
Index Credit Default Swaps. The Funds may invest in index credit default swaps (“CDX”). A CDX is a swap on an index of credit default swaps. CDXs allow an investor to manage credit risk or take a position on a basket of credit entities (such as credit default swaps or a commercial mortgage-backed index) in a more efficient manner than transacting in a single-name credit default swap. If a credit event occurs in one of the underlying companies, the protection is paid out via the delivery of the defaulted bond by the buyer of protection in return for a payment of notional value of the defaulted bond by the seller of protection or it may be settled through a cash settlement between the two parties. The underlying company is then removed from the index. New series of CDXs are issued on a regular basis.
Commercial mortgage-backed securities index swaps (“CMBX”) are a type of index credit default swap that are made up of tranches of commercial mortgage-backed securities rather than credit default swaps. CMBX involve a pay-as-you go settlement process designed to capture non-default events that affect the cash flow to the underlying mortgage-backed securities tranche.
Interest Rate Swaps. Interest rate swaps involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments). Interest rate swaps are generally entered into on a net basis. Interest rate swaps are centrally cleared and do not involve the delivery of securities, other underlying assets, or principal. Accordingly, the risk of loss with respect to interest rate swaps is limited to the net amount of interest payments that a Fund is contractually obligated to make.
Single-Name Credit Default Swaps. The Funds may invest in single-name credit default swaps (“CDS”) to buy or sell credit protection to hedge its credit exposure, gain issuer exposure without owning the underlying security, or increase a Fund’s total return. CDS are a specific kind of counterparty agreement that allow the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the CDS agrees to insure this risk in exchange for regular periodic payments.
TBA Commitments
Janus Henderson Sustainable & Impact Core Bond ETF may enter into “to be announced” or “TBA” commitments. TBA commitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities, for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet industry-accepted “good delivery” standards, which include specified terms, for issuer, rate, and mortgage terms. At the time the TBA commitment is made, the transaction is recorded and thereafter the value of such securities is reflected each day in determining the Fund’s NAV. Because the Fund is generally not required to pay for the security until the settlement date, if the Fund remains substantially fully invested at a time when TBA commitment purchases are outstanding, the purchases may result in a form of leverage.
U.S. Government Securities
The Funds may invest in U.S. Government securities. U.S. Government securities include those issued directly by the U.S. Treasury, including Treasury Inflation-Protected Securities (also known as TIPS), and those issued or guaranteed by various U.S. Government agencies and instrumentalities. Some government securities are backed by the full faith and credit of the United States. Other government securities are backed only by the rights of the issuer to borrow from the U.S. Treasury. Others are supported by the discretionary authority of the U.S. Government to purchase the obligations. Certain other government securities are supported only by the credit of the issuer. For securities not backed by the full faith and credit of the United States, a Fund must look principally to the agency or instrumentality issuing or guaranteeing the securities for repayment and may not be able to assert a claim against the United States if the agency or instrumentality does not meet its commitment. Such securities may involve increased risk of loss of principal and interest compared to government debt securities that are backed by the full faith and credit of the United States.
Because of the rising U.S. Government debt burden, it is possible that the U.S. Government may not be able to meet its financial obligations or that securities issued or backed by the U.S. Government may experience credit downgrades. Such a credit event may adversely affect the financial markets.
Variable- and Floating-Rate Obligations
The Funds may invest in securities with variable or floating rates of interest which, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate (the “underlying index”). The
 
28½Janus Detroit Street Trust

floating rate tends to decrease the security’s price sensitivity to changes in interest rates. These types of securities are relatively long-term instruments that often carry demand features permitting the holder to demand payment of principal at any time or at specified intervals prior to maturity. Inverse floating rate securities (“Inverse Floaters”) are debt instruments whose interest bears an inverse relationship to the interest rate on another security. A rise in the reference rate of an inverse floater will cause a drop in the interest rate paid by the inverse floater, while a drop in the reference rate of the inverse floater will cause an increase in the interest rate paid on the inverse floater. Inverse Floaters may exhibit greater price volatility than a fixed rate obligation with similar credit quality. Similar to variable and floating rate obligations, effective use of inverse floaters requires skills different from those needed to select most portfolio securities. If movements in interest rates are incorrectly anticipated, a Fund could lose money, or its NAV could decline by the use of inverse floaters.
Other Types of Investments
Unless otherwise stated within its specific investment policies, the Funds may also invest in other types of U.S. dollar denominated securities and use other investment strategies. These securities and strategies are not intended to be principal investment strategies of a Fund. If successful, they may benefit a Fund by earning a return on the Fund’s assets or reducing risk; however, they may not achieve the Fund’s investment objective. These securities and strategies may include fixed-income securities issued in private placement transactions.
 
RISKS OF THE FUNDS
The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Funds. The following information is intended to help you better understand some of the risks of investing in the Funds. The impact of the following risks on a Fund may vary depending on the Fund’s investments. The greater a Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in a Fund, you should consider carefully the risks that you assume when investing in the Fund.
Affiliated Underlying Fund Risk.  The Adviser may invest in certain affiliated ETFs as investments for each Fund. The Adviser will generally receive fees for managing such funds, in addition to the fees paid to the Adviser by each Fund. The payment of such fees by affiliated funds creates a conflict of interest when selecting affiliated funds for investment in a Fund. The Adviser, however, is a fiduciary to each Fund and its shareholders and is legally obligated to act in its best interest when selecting affiliated funds. In addition, the Adviser has contractually agreed to waive and/or reimburse a portion of such Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any of the affiliated ETFs with respect to such Fund’s investment in such ETF, less certain operating expenses.
Asset-Backed Securities Risk.  Asset-backed securities may be adversely affected by changes in interest rates, underperformance of the underlying assets, the creditworthiness of the entities that provide any supporting letters of credit, surety bonds, or other credit or liquidity enhancements. In addition, most asset-backed securities are subject to prepayment risk in a declining interest rate environment, and extension risk in an increasing rate environment.
Cash Transaction Risk.  The Funds may require all APs to purchase Creation Units in cash when the portfolio managers believe it is in the best interest of the Funds. Cash purchases may cause a Fund to incur portfolio transaction fees or charges or delays in investing the cash that it would otherwise not incur if a purchase was made on an in-kind basis. To the extent a Fund determines to effect a Creation Unit redemption on a cash basis, it may be less tax-efficient for the Fund compared to an in-kind redemption and may cause the Fund to incur portfolio transaction fees or charges it would not otherwise incur with an in-kind redemption, to the extent such fees or charges are not offset by the redemption transaction fee paid by APs. In addition, a Fund’s use of cash transactions may result in wider bid-ask spreads in Fund shares trading in the secondary market as compared to ETFs that transact exclusively on an in-kind basis.
Counterparty Risk.  Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to a Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to a Fund. A Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. A Fund may be exposed to counterparty risk to the extent it participates in lending its securities to third parties and/or cash sweep arrangements whereby the Fund’s cash balance is invested in one or more types of cash management vehicles or in time deposits. In addition, a Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements, debt securities, and derivatives (including various types of forwards, swaps, futures, and
 
29½Janus Detroit Street Trust

options). Each Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that a Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Credit Quality Risk.  Each Fund is subject to the risks associated with the credit quality of the issuers of fixed-income securities. Credit quality measures the likelihood that the issuer or borrower will meet its obligations on a bond. One of the fundamental risks is credit risk, which is the risk that an issuer will be unable to make principal and interest payments when due, or default on its obligations. Higher credit risk may negatively impact a Fund’s returns and yield.
Many fixed-income securities receive credit ratings from services such as Standard & Poor’s, Fitch, and Moody’s. These services assign ratings to securities by assessing the likelihood of issuer default. The lower a bond issue is rated by an agency, the more credit risk it is considered to represent. Lower rated instruments and securities generally pay interest at a higher rate to compensate for the associated greater risk. Interest rates can fluctuate in response to economic or market conditions, which can result in a fluctuation in the price of a security and impact a Fund’s return and yield. If a security has not received a rating, a Fund must rely upon the Adviser’s credit assessment, which if incorrect can also impact the Fund’s returns and yield. Please refer to the “Explanation of Rating Categories” section of this Prospectus for a description of bond rating categories.
Credit Risk Transfer Securities Risk.  CRT securities are unguaranteed and unsecured debt securities that are commonly issued by a government sponsored entity. CRTs are not directly linked to or backed by the underlying mortgage loans so investors such as the Fund have no direct recourse to the underlying mortgage loans in the event of a default. The risks associated with CRTs are different from the risks associated with investments in mortgage-backed securities issued by government sponsored entities or private issuers because some or all of the mortgage default or credit risk associated with the underlying mortgage loans is transferred to investors. Additional risks associated with investments in CRTs may include valuation risk, mortgage credit risk, liquidity risk, and prepayment risk.
Derivatives Risks. Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause a Fund to be more volatile than if it had not used leverage because leverage can exaggerate the effect of any increase or decrease in the value of securities and other instruments held by a Fund.
Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by a Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, a Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent a Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.
 
 
Index Credit Default Swaps Risk.  If a Fund holds a long position in a CDX, the Fund would indirectly bear its proportionate share of any expenses paid by a CDX. By investing in CDXs, a Fund could be exposed to illiquidity risk, counterparty risk, and credit risk of the issuers of the underlying loan obligations and of the CDX markets. If there is a default by the CDX counterparty, a Fund will have contractual remedies pursuant to the agreements related to the transaction. CDXs also bear the risk that a Fund will not be able to meet its obligation to the counterparty.
 
 
Interest Rate Swaps Risk.  A Fund’s use of interest rate swaps involves investment techniques and risks different from those associated with ordinary portfolio security transactions. Interest rate swaps may result in potential losses if interest rates do not move as expected or if the counterparties are unable to satisfy their obligations.
 
 
Single-Name Credit Default Swaps Risk.  When a Fund buys a single-name credit default swap (“CDS”), the Fund will receive a return on its investment only in the event of a credit event, such as default by the issuer of the underlying obligation (as opposed to a credit downgrade or other indication of financial difficulty). If a single-name CDS transaction is particularly large, or if the relevant market is illiquid, it may not be possible for a Fund to initiate a single-name CDS transaction or to liquidate its 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 single-name CDS in the event of the default or bankruptcy of the counterparty. The risks associated with cleared single-name CDS may be lower than that for uncleared single-name CDS
 
30½Janus Detroit Street Trust

 
because for cleared single-name CDS, the counterparty is a clearinghouse (to the extent such a trading market is available). However, there can be no assurance that a clearinghouse or its members will satisfy their obligations to a Fund. Unlike CDXs, single-name CDS do not have the benefit of diversification across many issuers.
Emerging Markets Risk.  Within the parameters of its specific investment policies, each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries include, but are not limited to, countries included in the MSCI Emerging Markets Index. To the extent that a Fund invests a significant amount of its assets in one or more of these countries, its returns and NAV may be affected to a large degree by events and economic conditions in such countries. The risks of foreign investing are heightened when investing in emerging markets, which may result in the price of investments in emerging markets experiencing sudden and sharp price swings. In many developing markets, there is less government supervision and regulation of stock exchanges, brokers, and listed companies than in more developed markets. Similarly, issuers in such markets may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which U.S. companies are subject. Information about emerging markets companies, including financial information, may be less available or reliable and the Fund’s ability to conduct due diligence with respect to such companies may be limited. In addition, certain emerging market jurisdictions materially restrict the Public Company Accounting Oversight Board’s (“PCAOB”) inspection, investigation, and enforcement capabilities which impairs the ability to conduct independent oversight or inspection of accounting firms located in, or operating in, certain emerging markets; therefore, there is no guarantee that the quality of financial reporting or the audits conducted by audit firms of emerging market issuers meet PCAOB standards. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on a Fund’s investments.
The securities markets of many of these emerging market countries may also be smaller, less liquid, and subject to greater price volatility than those in the United States. Moreover, the legal remedies for investors in emerging markets may be more limited than the remedies available in the United States and the ability of U.S. authorities (e.g., the SEC and the U.S. Department of Justice) to bring actions against bad actors may be limited. A shareholder’s ability to bring and enforce legal actions emerging market countries, or to obtain information needed to pursue or enforce such actions, may be limited and as a result such claims may be difficult or impossible to pursue. In the event of a default on any investments in foreign debt obligations, it may be more difficult for a Fund to obtain or to enforce a judgment against the issuers of such securities. In addition, a Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that a Fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. A Fund may be subject to emerging markets risk to the extent that it invests in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets.
Exchange-Traded Funds Risk.  Each Fund may invest in ETFs, including affiliated ETFs. ETFs are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the NAV of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its NAV. When a Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. As a result, the cost of investing in the Funds may be higher than the cost of investing directly in the underlying ETFs and may be higher than other ETFs or mutual funds that invest directly in stocks and bonds. ETFs also involve the risk that an active trading market for an ETF’s shares may not develop or be maintained. Similarly, because the value of ETF shares depends on the demand in the market, the Fund may not be able to purchase or sell an ETF at the most optimal time, which could adversely affect the Fund’s performance. In addition, ETFs that track particular indices may be unable to match the performance of such underlying indices due to the temporary unavailability of certain index securities in the secondary market or other factors, such as discrepancies with respect to the weighting of securities.
The ETFs in which a Fund invests are subject to specific risks, depending on the investment strategy of the ETF. In turn, a Fund will be subject to substantially the same risks as those associated with direct exposure to the securities or commodities held by the ETF. Because a Fund may invest in a broad range of ETFs, such risks may include, but are not limited to, leverage risk,
 
31½Janus Detroit Street Trust

foreign exposure risk, and commodity-linked investments risk. To the extent a Fund invests in fixed-income ETFs, it will be indirectly exposed to the same risks described under “Fixed-Income Securities Risk.”
Fixed-Income Securities Risk. Typically, the values of fixed-income securities change inversely with prevailing interest rates. Therefore, a fundamental risk of fixed-income securities is interest rate risk, which is the risk that the value of such securities will generally decline as prevailing interest rates rise, which may cause a Fund’s NAV to likewise decrease. How specific fixed-income securities may react to changes in interest rates will depend on the specific characteristics of each security. For example, while securities with longer maturities and durations tend to produce higher yields, they also tend to be more sensitive to changes in prevailing interest rates and are therefore more volatile than shorter-term securities and are subject to greater market fluctuations as a result of changes in interest rates. However, calculations of maturity and duration may be based on estimates and may not reliably predict a security’s price sensitivity to changes in interest rates. In addition, different interest rate measures (such as short- and long-term interest rates and U.S. and non-U.S. interest rates), or interest rates on different types of securities or securities of different issuers, may not necessarily change in the same amount or in the same direction. Investments in fixed-income securities with very low or negative interest rates may diminish a Fund’s yield and performance.
Fixed-income securities are also subject to credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default. In addition, there is prepayment risk, which is the risk that during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause a Fund to reinvest its assets in securities with lower yields, resulting in a decline in a Fund’s income or return potential. Fixed-income securities may also be subject to valuation risk and liquidity risk. Valuation risk is the risk that one or more of the fixed-income securities in which a Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer of the security. Liquidity risk is the risk that fixed-income securities may be difficult or impossible to sell at the time that the portfolio managers would like or at the price the portfolio managers believe the security is currently worth. Consequently, a Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk. To the extent a Fund invests in fixed-income securities in a particular industry or economic sector, its share values may fluctuate in response to events affecting that industry or sector. Securities underlying mortgage- and asset-backed securities, which may include subprime mortgages, also may be subject to a higher degree of credit risk, valuation risk, and liquidity risk. To the extent that a Fund invests in derivatives tied to fixed-income securities, the Fund may be more substantially exposed to these risks than a fund that does not invest in such derivatives. The market for certain fixed-income securities may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. Similarly, the amount of assets deemed illiquid remaining within a Fund may also increase, making it more difficult to meet shareholder redemptions and further adversely affecting the value of the Fund.
Foreign Exposure Risk.  The Funds may have exposure to foreign markets as a result of their investments in foreign securities, including investments in emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and NAV may be affected to a large degree by political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for a Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where a Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. A Fund’s investments in emerging market countries, if any, may involve risks greater than, or in addition to, the risks of investing in more developed countries.
High-Yield/High-Risk Bond Risk.  High-yield/high-risk bonds (or “junk” bonds) are bonds rated below investment grade by the primary rating agencies such as Standard & Poor’s, Fitch, and Moody’s or are unrated bonds of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield/high-risk bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings.
The secondary market on which high-yield securities are traded is less liquid than the market for investment grade securities. The lack of a liquid secondary market may have an adverse impact on the market price of the security. Additionally, it may be

more difficult to value the securities because valuation may require more research, and elements of judgment may play a larger role in the valuation because there is less reliable, objective data available.
Please refer to the “Explanation of Rating Categories” section of this Prospectus for a description of bond rating categories.
Industry and Sector Risk.  The Funds emphasize certain sustainable and ESG themes. As a result, at times, it may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector or that benefit from the same sustainable or ESG theme. Companies in the same industry or economic sector or that benefit from the same theme may be similarly affected by economic or market events, making a Fund more vulnerable to unfavorable developments than funds that invest more broadly. As a Fund’s portfolio becomes more concentrated, the Fund is less able to spread risk and potentially reduce the risk of loss and volatility.
Inflation Risk.  Inflation creates uncertainty over the future real value of an investment (the value after adjusting for inflation). The real value of certain assets or real income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of a Fund’s assets and distributions may decline. This risk is more prevalent with respect to debt securities held by a Fund. Inflation rates may change frequently and drastically as a result of various factors, including unexpected shifts in the domestic or global economy. Moreover, a Fund’s investments may not keep pace with inflation, which may result in losses to Fund shareholders or adversely affect the real value of shareholders’ investment in a Fund. Fund shareholders’ expectation of future inflation can also impact the current value of a Fund’s portfolio, resulting in lower asset values and potential losses. This risk may be elevated compared to historical market conditions because of recent monetary policy measures and the current interest rate environment.
Interest Rate Risk.  Generally, a fixed-income security will increase in value when prevailing interest rates fall and decrease in value when prevailing interest rates rise. Longer-term securities are generally more sensitive to interest rate changes than shorter-term securities, but they generally offer higher yields to compensate investors for the associated risks. High-yield bond prices and floating rate debt security prices are generally less directly responsive to interest rate changes than investment grade issues or comparable fixed rate securities, and may not always follow this pattern. An increase in interest rates may cause the value of fixed-income securities held by a Fund to decline. A Fund may be subject to a greater risk of rising interest rates due to inflationary trends and the effect of government fiscal and monetary policy initiatives and resulting market reaction to those initiatives. A Fund may manage interest rate risk by varying the average-weighted effective maturity of the portfolio to reflect an analysis of interest rate trends and other factors. A Fund’s average-weighted effective maturity will tend to be shorter when the portfolio managers expect interest rates to rise and longer when the portfolio managers expect interest rates to fall. A Fund may also use futures, swaps, options, and other derivatives to manage interest rate risk.
Leverage Risk.  Engaging in transactions using leverage or those having a leveraging effect subjects a Fund to certain risks. These risks may be heightened if a Fund invests all, or a significant portion of its assets in futures, forwards, swaps, and other types of derivatives. Leverage can magnify the effect of any gains or losses, causing a Fund to be more volatile than if it had not been leveraged. Through the use of leverage, a Fund’s total investment exposure could exceed the value of its portfolio securities and its investment performance could be dependent on securities not directly owned by the Fund. In addition, a Fund’s assets that are used as collateral to secure short sale transactions may decrease in value while the short positions are outstanding, which may force the Fund to use its other, additional assets to meet its collateral requirements.
LIBOR Replacement Risk.  Certain debt securities, derivatives, or other financial instruments utilize the London InterBank Offered Rate (“LIBOR”) as a reference rate for various rate calculations. The U.K. Financial Conduct Authority has ceased to publish or maintain as representative many LIBOR settings and will phase out certain other commonly-used U.S. dollar LIBOR settings as of June 30, 2023. The elimination of LIBOR or other reference rates and the transition process away from LIBOR could adversely impact (i) volatility and liquidity in markets that are tied to these reference rates, (ii) the market for, or value of, specific securities or payments linked to those reference rates, (iii) the availability or terms of borrowing or refinancing, or (iv) the effectiveness of hedging strategies. For these and other reasons, the elimination of LIBOR or other reference rates may adversely affect each Fund’s performance and/or NAV. Alternatives to LIBOR are established or in development in most major currencies including the Secured Overnight Financing Rate (“SOFR”) that is intended to replace the U.S. dollar LIBOR.
The effect of the discontinuation of LIBOR or other reference rates on a Fund will vary depending on, among other things (i) existing fallback or termination provisions in individual contracts and (ii) whether, how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new products and instruments. Accordingly, it is difficult to predict the full impact of the transition away from LIBOR or other reference rates on a Fund until new reference rates and fallbacks for both legacy and new products, instruments, and contracts are commercially accepted.

Liquidity Risk. The Funds may invest in securities or instruments that do not trade actively or in large volumes, and may make investments that are less liquid than other investments. Also, the Funds may make investments that may become less liquid in response to market developments or adverse investor perceptions. Investments that are illiquid or that trade in lower volumes may be more difficult to value. When there is no willing buyer and investments cannot be readily sold at the desired time or price, a Fund may have to accept a lower price or may not be able to sell the security or instrument at all. Investments in foreign securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk than domestic securities. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). An inability to sell one or more portfolio positions can adversely affect a Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities. Liquidity risk may be increased to the extent that a Fund invests in restricted securities that are deemed to be illiquid investments.
Loan Risk. The Funds may invest in bank loans. Additionally, the Janus Henderson Sustainable & Impact Core Bond ETF may also invest in various commercial loans, including bank loans, bridge loans, and mezzanine loans, and other fixed and floating rate loans. Bank loans are obligations of companies or other entities entered into in connection with recapitalizations, acquisitions, and refinancings. A Fund’s investments in bank loans are generally acquired as a participation interest in, or assignment of, loans originated by a lender or other financial institution. These investments may include institutionally-traded floating and fixed-rate debt securities. The bank loans underlying these securities often involve borrowers with low credit ratings whose financial conditions are troubled or uncertain, including companies that are highly leveraged or in bankruptcy proceedings. Participation interests and assignments involve credit, interest rate, and liquidity risk. Some participation interests and assignments may not be considered “securities,” and purchasers, such as an underlying fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws. Additionally, because the Adviser, in the course of investing a Fund’s assets in loans, may have access to material non-public information regarding the borrower, the ability of an underlying fund to purchase or sell publicly-traded securities of such borrowers may be restricted. Most bridge loans are structured as floating-rate debt with step-up provisions under which the interest rate on the bridge loan increases the longer the loan remains outstanding. In addition to the risks associated with bank loans, an investment in bridge loans may subject a Fund to certain risks, including the risk that a borrower may be unable to locate permanent financing to replace the bridge loan, which may impair the borrower’s perceived creditworthiness. Mezzanine loans generally are rated below investment grade, and frequently are unrated. Because mezzanine loans typically are the most subordinated debt obligation in an issuer’s capital structure, they are subject to the additional risk that the cash flow of the related borrower and any property securing the loan may be insufficient to repay the loan after the related borrower pays off any senior obligations.
Market Risk. The value of a Fund’s portfolio may decrease if the value of one or more issuers in the Fund’s portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities prices, or if the market favors different types of securities than the types of securities in which a Fund invests. If the value of a Fund’s portfolio decreases, the Fund’s NAV will also decrease, which means if you sell your shares in the Fund you may lose money. Market risk may affect a single issuer, industry, economic sector, or the market as a whole.
The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, conflicts, including related sanctions, and social unrest, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
 
 
COVID-19 Pandemic. The effects of COVID-19 have contributed to increased volatility in global financial markets and have affected and may continue to affect certain countries, regions, issuers, industries and market sectors more dramatically than others. These conditions and events could have a significant impact on a Fund and its investments, a Fund’s ability to meet redemption requests, and the processes and operations of a Fund’s service providers, including the Adviser.
 
 
Russia/Ukraine Invasion. Russia launched a large-scale invasion of Ukraine on February 24, 2022. The extent and duration of the military action, resulting sanctions and resulting future market disruptions in the region are impossible to predict, but could be significant and have a severe adverse effect on the region, including significant negative impacts on the economy and the markets for certain securities and commodities, such as oil and natural gas, as well as other sectors.

Market Trading Risk. The Funds are subject to secondary market trading risks. Shares of a Fund are listed for trading on an exchange; however, there can be no guarantee that an active trading market for such shares will develop or continue. Shares of a Fund may be listed or traded on U.S. and foreign exchanges other than the Fund’s primary U.S. listing exchange. There can be no guarantee that a Fund’s shares will continue trading on any exchange or in any market or that the Fund’s shares will continue to meet the listing or trading requirements of any exchange or market. A Fund’s shares may experience higher trading volumes on one exchange as compared to another and investors are subject to the execution and settlement risks of the market where their broker directs trades.
Secondary market trading in a Fund’s shares may be halted by an exchange because of market conditions. Pursuant to exchange or market rules, trading in a Fund’s shares on an exchange or in any market may be subject to trading halts caused by extraordinary market volatility. There can be no guarantee that a Fund’s exchange listing or ability to trade its shares will continue or remain unchanged. In the event a Fund ceases to be listed on an exchange, the Fund may cease operating as an “exchange-traded” fund and operate as a mutual fund, provided that shareholders are given advance notice.
Shares of a Fund may trade on an exchange at prices at, above, or below their most recent NAV. The per share NAV of a Fund is calculated at the end of each business day, as described below, and fluctuates with changes in the market value of the Fund’s holdings. The trading prices of a Fund’s shares fluctuate continuously throughout the trading day based on market supply and demand, and may not closely track NAV. The trading prices of a Fund’s shares may differ significantly from NAV during periods of market volatility, which may, among other factors, lead to the Fund’s shares trading at a premium or discount to NAV.
Buying or selling a Fund’s shares on an exchange may require the payment of brokerage commissions. In addition, you may also incur the cost of the spread (the difference between the bid price and the ask price). The commission is frequently a fixed amount and may be a significant cost for investors seeking to buy or sell small amounts of shares. The spread varies over time for shares of a Fund based on its trading volume and market liquidity, and is generally less if the Fund has more trading volume and market liquidity and more if the Fund has less trading volume and market liquidity. Due to the costs inherent in buying or selling a Fund’s shares, frequent trading may detract significantly from investment returns. Investment in a Fund’s shares may not be advisable for investors who expect to engage in frequent trading.
Money Market Fund Investment Risk.  A Fund may have cash balances that have not been invested in portfolio securities, which may be used to purchase shares of affiliated or non-affiliated money market funds, or cash management pooled investment vehicles that operate as money market funds, as part of a cash sweep program. By investing in a money market fund, a Fund will be exposed to the investment risks of the money market fund in direct proportion to such investment. The money market fund may not achieve its investment objective and a Fund may lose money. To the extent a Fund transacts in instruments such as derivatives, such Fund may hold investments, which may be significant, in money market fund shares to cover its obligations resulting from such Fund’s investments in derivatives. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. There can be no assurance that a money market fund will maintain a $1.00 per share NAV at all times. Factors that could adversely affect the value of a money market fund’s shares include, among other things, a sharp rise in interest rates, an illiquid market for the securities held by the money market fund, a high volume of redemption activity in a fund’s shares, and a credit event or credit rating downgrade affecting one or more of the issuers of securities held by the money market fund. In addition, the failure of even an unrelated money market fund to maintain a stable NAV could create a widespread risk of increased redemption pressures on all money market funds, potentially jeopardizing the stability of their NAVs. Certain money market funds have in the past failed to maintain stable NAVs, and there can be no assurance that such failures and resulting redemption pressures will not impact money market funds in the future.
Rules adopted by the SEC require, among other things, certain money market funds to cause transactions in shares of these funds to be effected using a fund’s NAV per share calculated out to the fourth decimal point (e.g., $1.0000 instead of $1.00). “Government Money Market Funds” and “Retail Money Market Funds” as defined in Rule 2a-7 under the Investment Company Act of 1940, as amended, are not subject to the floating NAV requirements. In addition, certain money market funds may impose a fee upon sale of shares or may temporarily suspend the ability to sell shares of the money market fund if the money market fund’s liquidity falls below required minimums because of market conditions or other factors.
There can be no assurance that a Fund’s investments in money market funds are not adversely affected by reforms to money market regulation that may be adopted by the SEC or other regulatory authorities.
 
35½Janus Detroit Street Trust

In addition to the fees and expenses that a Fund directly bears, a Fund indirectly bears the fees and expenses of any money market fund in which it invests.
Mortgage-Backed Securities Risk.  Mortgage-backed securities are classified generally as either commercial mortgage-backed securities or residential mortgage-backed securities, each of which is subject to certain specific risks. Mortgage-backed securities tend to be more sensitive to changes in interest rates than other types of debt securities. Investments in mortgage-backed securities are subject to both extension risk and prepayment risk. These risks may reduce a Fund’s returns. In addition, investments in mortgage-backed securities, including those comprised of subprime mortgages, may be subject to a higher degree of credit risk, valuation risk, and liquidity risk than various other types of fixed-income securities.
Newly Issued Securities Risk.  The credit obligations in which a Fund invests may include newly issued securities, or “new issues,” such as initial debt offerings. New issues may have a magnified impact on the performance of a Fund during periods in which it has a small asset base. The impact of new issues on a Fund’s performance likely will decrease as the Fund’s asset size increases, which could reduce the Fund’s returns. New issues may not be consistently available to a Fund for investing, particularly as the Fund’s asset base grows. Certain new issues, such as initial debt offerings, may be volatile in price due to the absence of a prior trading market, limited quantities available for trading and limited information about the issuer. A Fund may hold new issues for a short period of time. This may increase a Fund’s portfolio turnover and may lead to increased expenses for the Fund, such as commissions and transaction costs. In addition, new issues can experience an immediate drop in value after issuance if the demand for the securities does not continue to support the offering price.
Operational Risk.  An investment in a Fund can involve operational risks arising from factors such as processing errors, human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in key personnel, technology and/or service providers, and errors caused by third party service providers. Among other things, these errors or failures, as well as other technological issues, may adversely affect a Fund’s ability to calculate its NAV, process fund orders, execute portfolio trades or perform other essential tasks in a timely manner, including over a potentially extended period of time. These errors or failures may also result in a loss or compromise of information, regulatory scrutiny, reputational damage or other events, any of which could have a material adverse effect on a Fund. Implementation of business continuity plans by a Fund, the Adviser or third-party service providers in response to disruptive events such as natural disasters, epidemics and pandemics, terrorism, conflicts and social unrest may increase these operational risks to the Fund. While a Fund seeks to minimize such events through internal controls and oversight of third-party service providers, there is no guarantee that the Fund will not suffer losses if such events occur.
Portfolio Management Risk.  The Funds are actively managed investment portfolios and are therefore subject to the risk that the portfolio managers may not be successful in identifying investment opportunities that are aligned with the sustainable and/or impact investment approaches that the Funds employ. A Fund may underperform its benchmark index or other funds with similar investment objectives.
Private Placements and Other Restricted Securities Risk.  Investments in private placements and other restricted securities could decrease a Fund’s liquidity profile or prevent a Fund from disposing of them promptly at advantageous prices. Private placements and restricted securities may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available. Transaction costs may be higher for these securities, and a Fund may get only limited information about the issuer of a private placement or other restricted security.
Reverse Repurchase Agreement Risk.  Reverse repurchase agreements are transactions in which a Fund sells a security and simultaneously commits to repurchase that security from the buyer, such as a bank or broker-dealer, at an agreed upon price on an agreed upon future date. The repurchase price consists of the sale price plus an incremental amount reflecting the interest cost to a Fund on the proceeds it has received from the initial sale. Reverse repurchase agreements involve the risk that the value of securities that a Fund is obligated to repurchase under the agreement may decline below the repurchase price. Additionally, such transactions are only advantageous if the interest cost to a Fund of the reverse repurchase transaction is less than the cost of obtaining the cash otherwise. Interest costs on the proceeds received in a reverse repurchase agreement may exceed the return received on the investments made by a Fund with those proceeds, resulting in reduced returns to shareholders. When a Fund enters into a reverse repurchase agreement, it is subject to the risk that the buyer (counterparty) may default on its obligations to the Fund. In the event of such a default, a Fund may experience delays, costs, and losses, all of which may reduce returns to shareholders. Investing reverse repurchase proceeds may also have a leveraging effect on a Fund’s portfolio. A Fund’s use of
 
36½Janus Detroit Street Trust

leverage can magnify the effect of any gains or losses, causing the Fund to be more volatile than if it had not been leveraged. There is no assurance that any leveraging strategy used by a Fund will be successful.
Sustainable Investment Risk.  The Funds follow a sustainable investment approach by investing in debt securities that are aligned with positive environmental and social impact themes and/or the debt of companies with business practices that the Adviser believes to be sustainable and/or demonstrate adherence to certain sustainable and/or ESG-related practices. Accordingly, a Fund may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector. Additionally, due to its exclusionary criteria, a Fund may not be invested in certain industries or sectors. As a result, the Fund may be overweight or underweight in certain industries or sectors relative to its benchmark index, which may cause the Fund’s performance to be more or less sensitive to developments affecting those sectors. In addition, because sustainable and ESG investing takes into consideration factors beyond traditional financial analysis, the investment opportunities for a Fund may be limited at times. Sustainability and ESG-related information provided by issuers and third parties, upon which the portfolio managers may rely, continues to develop, and may be incomplete, inaccurate, use different methodologies, or be applied differently across companies and industries. Further, the regulatory landscape for sustainable and ESG investing in the United States is still developing and future rules and regulations may require a Fund to modify or alter its investment process. Similarly, government policies incentivizing companies to engage in sustainable and ESG practices may fall out of favor, which could potentially limit a Fund’s investment universe. There is also a risk that the companies identified through the investment process may fail to adhere to sustainable and/or ESG-related business practices, which may result in a Fund selling a security when it might otherwise be disadvantageous to do so. There is no guarantee that sustainable investments will outperform the broader market on either an absolute or relative basis.
Trading Issues Risk.  Although Fund shares are listed for trading on the Exchange, there can be no assurance that an active trading market for such shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in shares is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of a Fund will continue to be met or will remain unchanged or that the shares will trade with any volume, or at all. In addition, during periods of significant volatility, the liquidity of the underlying securities held by a Fund may affect the Fund’s trading prices. During a “flash crash,” the market prices of a Fund’s shares may decline suddenly and significantly. Such a decline may not reflect the performance of the portfolio securities held by a Fund. Flash crashes may cause APs and other market makers to limit or cease trading in a Fund’s shares for temporary or longer periods. Shareholders could suffer significant losses to the extent that they sell shares at these temporarily low market prices.
Transaction and Spread Risk.  Investors buying or selling Fund shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions can be a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of shares. In addition, secondary market investors will also incur the cost of the difference between the price that an investor is willing to pay for shares (the “bid” price) and the price at which an investor is willing to sell shares (the “ask” price). This difference in bid and ask prices is often referred to as the “spread” or “bid/ask spread.” The bid/ask spread varies over time for shares based on trading volume and market liquidity, and is generally lower if a Fund’s shares have more trading volume and market liquidity and higher if the Fund’s shares have little trading volume and market liquidity. Further, increased market volatility and trading halts affecting any of a Fund’s portfolio securities may cause increased bid/ask spreads. Due to the costs of buying or selling shares, including bid/ask spreads, frequent trading of shares may significantly reduce investment results and an investment in shares may not be advisable for investors who anticipate regularly making small investments.

MANAGEMENT OF THE FUNDS
 
 
 
INVESTMENT ADVISER
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to each Fund. The Adviser is responsible for the day-to-day management of each Fund’s investment portfolio and furnishes continuous advice and recommendations concerning each Fund’s investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of each Fund. The Adviser utilizes a personnel-sharing arrangement with its foreign (non-U.S.) affiliate, Janus Henderson Investors UK Limited (“JHIUKL”), pursuant to which certain Janus Henderson employees acting for JHIUKL may also serve as “associated persons” of the Adviser. In this capacity, such Janus Henderson employees, acting for JHIUKL, are subject to the oversight and supervision of the Adviser and may provide portfolio management, research, and related services to the Funds on behalf of the Adviser.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
Each Fund may rely on the SEC exemptive and no action relief that permits the Adviser, subject to the approval of the Trustees, to appoint or replace affiliated and unaffiliated subadvisers to manage all or a portion of each Fund’s assets and enter into, amend, or terminate such subadvisory agreements without obtaining shareholder approval (a “manager-of-managers structure”).
Pursuant to the relief, the Adviser, with the approval of the Trustees, has the ultimate responsibility, subject to oversight by the Board, to oversee subadvisers and recommend their hiring, termination and replacement. The Adviser, subject to the review and oversight of the Trustees, has responsibility to: set each Fund’s overall investment strategy; evaluate, select and recommend subadvisers to manage all or a portion of each Fund’s assets; and implement procedures reasonably designed to ensure that each subadviser complies with each Fund’s investment goal, policies and restrictions. Subject to review and oversight by the Trustees, under the manager-of-managers structure, the Adviser will allocate and, when appropriate, reallocate each Fund’s assets among subadvisers and monitor and evaluate the subadvisers’ performance. The relief also permits each Fund to disclose subadvisers’ fees only in the aggregate in the SAI. In the event that the Adviser hires a new subadviser pursuant to the manager-of-managers structure, the affected Fund would provide shareholders with information about the new subadviser and subadvisory agreement within 90 days.
The Trustees and the initial shareholder of each Fund have approved the use of a manager-of-managers structure for each Fund.
 
MANAGEMENT EXPENSES
Each Fund uses a unitary fee structure, under which each Fund pays the Adviser a “Management Fee” in return for providing certain investment advisory, supervisory, and administrative services to each Fund, including the costs of transfer agency, custody, fund administration, legal, audit, and other services. The Adviser’s fee structure is designed to pay substantially all of each Fund’s expenses. However, each Fund bears other expenses which are not covered under the Management Fee which may vary and affect the total level of expenses paid by shareholders, such as distribution fees (if any), brokerage expenses or commissions, interest and dividends (including those relating to short positions (if any)), taxes, litigation expenses, acquired fund fees and expenses (if any), and extraordinary expenses.
Each Fund’s Management Fee is calculated daily and paid monthly. Each Fund’s advisory agreement details the Management Fee and other expenses that such Fund must pay.

A discussion regarding the basis for the Trustees’ approval of each Fund’s investment advisory agreement is included in each Fund’s semiannual report (for the period ending April 30) to shareholders. You can request each Fund’s annual or semiannual reports (as they become available), free of charge, by contacting your broker-dealer, plan sponsor, or financial intermediary, or by contacting a representative at 1-800-668-0434. The reports are also available, free of charge, at janushenderson.com/info.
Expense Limitation
The Adviser has contractually agreed to waive and/or reimburse a portion of each Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any affiliated ETFs in which the Fund invests. Pursuant to this agreement, the waiver amount is equal to the amount of Fund assets invested in the affiliated ETF, multiplied by an amount equal to the current daily unitary management fee of the affiliated ETF less certain asset-based operating fees and expenses incurred on a per-fund basis and paid by the Adviser with respect to the affiliated ETF (including, but not limited to custody, sub-administration and transfer agency fees). The fee waiver agreement will remain in effect at least through February 29, 2024. The fee waiver agreement may be modified or terminated prior to this date only at the discretion of the Board of Trustees.

Mr. Wilensky holds a Bachelor of Science degree in Business Administration from Washington University and a Master’s degree in Business Administration from the University of Chicago. He holds the Chartered Financial Analyst designation.
Information about the portfolio managers’ compensation structure and other accounts managed, as well as the aggregate range of their individual ownership in the Fund(s) that they manage, is included in the SAI.
Conflicts of Interest
The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades.
In addition, from time to time, the Adviser or its affiliates may, subject to compliance with applicable law, purchase and hold shares of a Fund for their own accounts, or may purchase shares of a Fund for the benefit of their clients, including other Janus Henderson funds. Increasing each Fund’s assets may enhance the Fund’s profile with financial intermediaries and platforms, investment flexibility and trading volume. The Adviser and its affiliates reserve the right, subject to compliance with applicable law, to dispose of at any time some or all of the shares of a Fund acquired for their own accounts or for the benefit of their clients. A large sale of Fund shares by the Adviser or its affiliates could significantly reduce the asset size of each Fund, which might have an adverse effect on the Fund’s investment flexibility or trading volume. The Adviser considers the effect of redemptions on each Fund and other shareholders in deciding whether to dispose of its shares of the Fund.
The Adviser believes it has appropriately designed and implemented policies and procedures to mitigate these and other potential conflicts of interest. A further discussion of potential conflicts of interest and policies and procedures intended to mitigate them is contained in the Funds’ SAI.

OTHER INFORMATION
 
 
 
DISTRIBUTION OF THE FUNDS
Creation Units for the Funds are distributed by ALPS Distributors, Inc. (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

DIVIDENDS, DISTRIBUTIONS AND TAXES
 
 
 
DISTRIBUTIONS
To avoid taxation of each Fund, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires each Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually.
Distribution Schedule
Dividends from net investment income are generally declared and distributed to shareholders monthly. Distributions of net capital gains are declared and distributed at least annually. Dividends may be declared and paid more frequently to comply with the distribution requirements of the Internal Revenue Code. The date you receive your distribution may vary depending on how your intermediary processes trades. Dividend payments are made through Depository Trust Company (“DTC”) participants and indirect participants to beneficial owners then of record with proceeds received from each Fund. Please consult your financial intermediary for details.
How Distributions Affect each Fund’s NAV
Distributions are paid to shareholders as of the record date of a distribution of each Fund, regardless of how long the shares have been held. Undistributed income and net capital gains are included in each Fund’s daily NAV. A Fund’s NAV drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, a Fund declared a dividend in the amount of $0.25 per share. If a Fund’s NAV was $10.00 on December 30, the Fund’s NAV on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable fund do not increase the value of your investment and may create income tax obligations.
No dividend reinvestment service is provided by the Trust. Financial intermediaries may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of Fund shares for reinvestment of their dividend distributions. Beneficial owners should contact their financial intermediary to determine the availability and costs of the service and the details of participation therein. Financial intermediaries may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and net capital gains will be automatically reinvested in additional whole shares of a Fund purchased in the secondary market.
 
TAXES
As with any investment, you should consider the tax consequences of investing in each Fund. The following is a general discussion of certain federal income tax consequences of investing in a Fund. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in a Fund. You should consult your tax adviser regarding the effect that an investment in a Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by a Fund are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of the Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term capital gain rates, provided certain holding period and other requirements are satisfied.
Dividends received from real estate investment trusts (“REITs”), certain foreign corporations, and income received “in lieu of” dividends in a securities lending transaction generally will not constitute qualified dividend income. Because the income of a Fund is primarily derived from investments earning interest rather than dividend income, generally none or only a small portion of the income dividends paid by the Fund is anticipated to be qualified dividend income. Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment income includes dividends paid by a Fund and capital gains from any sale or exchange of Fund shares. A Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although a Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be
 
42½Janus Detroit Street Trust

treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (“IRS”).
Taxes on Sales
Any time you sell the shares of a Fund in a taxable account, it is considered a taxable event. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility.
U.S. federal income tax withholding may be required on all distributions payable to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS that they are subject to backup withholding. The current backup withholding rate is applied.
For shares purchased and sold from a taxable account, your intermediary will report cost basis information to you and to the IRS. Your financial intermediary will permit shareholders to elect their preferred cost basis method. In the absence of an election, your cost basis method will be your financial intermediary’s default method, which is often the average cost method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.
Taxation of the Funds
Dividends, interest, and some capital gains received by a Fund on foreign securities may be subject to foreign tax withholding or other foreign taxes.
Certain fund transactions may involve futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, and timing of distributions to shareholders, and utilization of capital loss carryforwards. A Fund will monitor its transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible.
A Fund does not expect to pay any federal income or excise taxes because it intends to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all its net investment income and net capital gains. It is important for a Fund to meet these requirements so that any earnings on your investment will not be subject to federal income tax twice. If a Fund invests in a partnership, however, it may be subject to state tax liabilities.
If a Fund redeems Creation Units in cash, it may recognize more capital gains than it will if it redeems Creation Units in-kind.
For additional information, see the “Income Dividends, Capital Gains Distributions, and Tax Status” section of the SAI.

SHAREHOLDERS GUIDE
 
 
 
Each Fund issues or redeems its shares at NAV per share only in Creation Units. Shares of each Fund are listed for trading on a national securities exchange and trade on the secondary market during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly traded companies. There is no minimum investment. When buying or selling Fund 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 offered price in the secondary market on each purchase and sale transaction. Fund shares are traded on the Exchange under the trading symbol SCRD for Janus Henderson Sustainable Corporate Bond ETF and JIB for Janus Henderson Sustainable & Impact Core Bond ETF. Share prices are reported in dollars and cents per share.
APs may acquire Fund shares directly from each Fund, and APs may tender their Fund shares for redemption directly to the Fund, at NAV per share, only in Creation Units and in accordance with the procedures described in the Funds’ SAI.
 
PRICING OF FUND SHARES
The per share NAV of each Fund is computed by dividing the total value of the Fund’s portfolio, less any liabilities, by the total number of outstanding shares of the Fund. Each Fund’s NAV is calculated as of the close of the trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“Business Day”). However, the NAV may still be calculated if trading on the NYSE is restricted, provided there is sufficient pricing information available for a Fund to value its securities, or as permitted by the SEC. Foreign securities held by a Fund, as applicable, may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of a Fund’s holdings may change on days that are not Business Days in the United States and on which you will not be able to purchase or sell the Fund’s shares.
Securities held by each Fund are valued in accordance with policies and procedures established by the Adviser pursuant to Rule 2a-5 under the Investment Company Act of 1940 (the “1940 Act”) and approved by and subject to the oversight of the Trustees (“Valuation Procedures”). To the extent available, equity securities (including shares of exchange-traded funds) are generally valued at readily available market quotations, which are (i) the official close prices or (ii) last sale prices on the primary market or exchange in which the securities trade. Most fixed-income securities are typically valued using an evaluated bid price supplied by an Adviser-approved pricing service that is intended to reflect market value. The evaluated bid price is an evaluation that may consider factors such as security prices, yields, maturities, and ratings. Certain short-term instruments maturing within 60 days or less may be valued at amortized cost, which approximates market value. If a market quotation or evaluated price for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is traded, and before the close of the NYSE, a fair value of the security will be determined in good faith by the Adviser pursuant to the Valuation Procedures. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. This type of fair valuation may be more commonly used with foreign equity securities, but it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. Special valuation considerations may apply with respect to “odd-lot” fixed-income transactions which, due to their small size, may receive evaluated prices by pricing services which reflect a large block trade and not what actually could be obtained for the odd-lot position. For valuation purposes, if applicable, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The methodologies employed when fair valuing securities may change from time to time. Because fair value pricing involves subjective judgments, it is possible that the fair value determination for a security may be different than the value that could be realized when selling that security.
The value of the securities of mutual funds held by each Fund, if any, will be calculated using the NAV of such mutual funds, and the prospectuses for such mutual funds explain the circumstances under which they use fair valuation and the effects of using fair valuation.
All purchases, sales, or other account activity must be processed through your financial intermediary or plan sponsor.
 
DISTRIBUTION AND SERVICING FEES
Distribution and Shareholder Servicing Plan
The Trust has adopted a Distribution and Servicing Plan for shares of each Fund pursuant to Rule 12b-1 under the 1940 Act (the “Plan”). The Plan permits compensation in connection with the distribution and marketing of Fund shares and/or the
 
44½Janus Detroit Street Trust

provision of certain shareholder services. The Plan permits each Fund to pay the Distributor, or its designee, a fee for the sale and distribution and/or shareholder servicing of the shares at an annual rate of up to 0.25% of average daily net assets of the shares of the Fund (“12b-1 fee”). However, payment of a 12b-1 fee has not been authorized at this time.
Under the terms of the Plan, the Trust is authorized to make payments to the Distributor or its designee for remittance to retirement plan service providers, broker-dealers, bank trust departments, financial advisors, and other financial intermediaries, as compensation for distribution and/or shareholder services performed by such entities for their customers who are investors in each Fund.
The 12b-1 fee may only be imposed or increased when the Trustees determine that it is in the best interests of shareholders to do so. Because these fees are paid out of each Fund’s assets on an ongoing basis, to the extent that a fee is authorized and payments are made, over time they will increase the cost of an investment in the Fund. The 12b-1 fee may cost an investor more than other types of sales charges.
 
PAYMENTS TO FINANCIAL INTERMEDIARIES BY ADVISER OR ITS AFFILIATES
From their own assets, the Adviser or its affiliates pay selected brokerage firms or other financial intermediaries for making certain funds available to their clients or otherwise distributing, promoting or marketing the funds. The Adviser or its affiliates also make payments to one or more intermediaries for information about transactions and holdings in the funds, such as the amount of fund shares purchased, sold or held through the intermediary and or its salespersons, the intermediary platform(s) on which shares are transacted and other information related to the funds. Payments made by the Adviser and its affiliates may eliminate or reduce trading commissions that the intermediary would otherwise charge its customers or its salespersons in connection with the purchase or sale of certain funds. Payment by the Adviser or its affiliates to eliminate or reduce a trading commission creates an incentive for salespersons of the intermediary to sell the Janus Henderson funds over other funds for which a commission would be charged. The amount of these payments is determined from time to time by the Adviser, may be substantial, and may differ for different intermediaries. The Adviser may determine to make payments based on any number of factors or metrics. For example, the Adviser may make payments at year-end and/or other intervals in a fixed amount, an amount based upon an intermediary’s services at defined levels, an amount based upon the total assets represented by funds subject to arrangements with the intermediary, or an amount based on the intermediary’s net sales of one or more funds in a year or other period, any of which arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. Payments based primarily on sales create an incentive to make new sales of shares, while payments based on assets create an incentive to retain previously sold shares. The Adviser currently maintains asset-based agreements with certain intermediaries on behalf of the Trust. The amount of compensation paid by the Adviser varies from intermediary to intermediary. More information regarding these payments is contained in the Funds’ SAI.
With respect to non-exchange-traded Janus Henderson funds not offered in this Prospectus, the Adviser or its affiliates pay fees, from their own assets, to selected brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries that sell the Janus Henderson funds for distribution, marketing, promotional, or related services, and/or for providing recordkeeping, subaccounting, transaction processing, and other shareholder or administrative services (including payments for processing transactions via National Securities Clearing Corporation (“NSCC”) or other means) in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services. Shareholders investing through an intermediary should consider whether such arrangements exist when evaluating any recommendations from an intermediary.
In addition, the Adviser or its affiliates may also share certain marketing expenses with intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, and support for marketing materials, sales reporting, or business building programs for such intermediaries to raise awareness of the Janus Henderson funds. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with
 
45½Janus Detroit Street Trust

educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments, reimbursements and other forms of compensation described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other funds (or non-mutual fund investments), with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell shares of the Funds. Please contact your financial intermediary or plan sponsor for details on such arrangements.
 
PURCHASING AND SELLING SHARES
Shares of each Fund are listed for trading on a national securities exchange during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly traded companies. However, there can be no guarantee that an active trading market will develop or be maintained, or that each Fund shares listing will continue or remain unchanged. Each Fund does not impose any minimum investment for shares of the Fund purchased on an exchange. Buying or selling each Fund’s shares involves certain costs that apply to all securities transactions. When buying or selling shares of each Fund through a financial intermediary, you may incur a brokerage commission or other charges determined by your financial intermediary. Due to these brokerage costs, if any, frequent trading may detract significantly from investment returns. In addition, you may also incur the cost of the spread (the difference between the bid price and the ask price). The commission is frequently a fixed amount and may be a significant cost for investors seeking to buy or sell small amounts of shares.
Shares of each Fund may be acquired through the Distributor or redeemed directly with the Fund only in Creation Units or multiples thereof, as discussed in the “Creation and Redemption of Creation Units” section of the Funds’ SAI. Once created, shares of each Fund generally trade in the secondary market in amounts less than a Creation Unit.
Each Fund’s primary listing exchange is NYSE Arca (the “Exchange”). The Exchange is open for trading Monday through Friday and is closed on the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.
A Business Day with respect to each Fund is each day the Exchange is open. Orders from APs to create or redeem Creation Units will only be accepted on a Business Day. On days when the Exchange or bond market closes earlier than normal (or on days the bond market is closed but the Exchange is open), each Fund may require orders to create or redeem Creation Units to be placed earlier in the day. In addition, to minimize brokerage and other related trading costs associated with securities that cannot be readily transferred in-kind, each Fund may establish early trade cut-off times for APs to submit orders for Creation Units, in accordance with the 1940 Act. See the Funds’ SAI for more information.
In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), your financial intermediary is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, social security number, and permanent street address to assist in verifying your identity. You may also be asked to provide additional documents that may help to establish your identity. Until verification of your identity is made, your financial intermediary may temporarily limit additional share purchases. In addition, your financial intermediary may close an account if it is unable to verify your identity. Please contact your financial intermediary if you need additional assistance when completing your application or additional information about your financial intermediary’s Anti-Money Laundering Program.
 
46½Janus Detroit Street Trust

In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.
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 Fund on an ongoing basis, a “distribution,” as such term is used in the Securities Act of 1933, as amended (the “Securities 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 requirements and liability provisions of the Securities Act. For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent shares and sells the shares directly to customers or if it chooses to couple the creation of a supply of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a characterization as an underwriter.
Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3)(C) 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 contrasted with engaging in ordinary secondary market transactions) and thus dealing with the shares that are part of an unsold allotment within the meaning of Section 4(a)(3)(C) of the Securities Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(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.
Book Entry
Shares of each Fund are held in book-entry form, which means that no stock certificates are issued. The DTC or its nominee is the record owner of all outstanding shares of each Fund and is recognized as the owner of all shares for all purposes.
Investors owning shares of each Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Funds. DTC participants 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 exchange-traded securities that you hold in book-entry or “street name” form.
Share Prices
The trading prices of each Fund’s shares in the secondary market generally differ from the Fund’s daily NAV per share and are affected by market forces such as supply and demand, economic conditions, and other factors. Information regarding the intra-day net asset value of each Fund is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are primarily listed or by market data vendors or other information providers. The intra-day net asset value calculations are estimates of the value of each Fund’s NAV per Fund share based on the current market value of the securities and/or cash included in the Fund’s intra-day net asset value basket. The intra-day net asset value does not necessarily reflect the precise composition of the current portfolio of securities and instruments held by each Fund at a particular point in time. Additionally, when current pricing is not available for certain portfolio securities the intra-day indicative value may not accurately reflect the current market value of each Fund’s shares or the best possible valuation of the current portfolio. For example, the intra-day net asset value is based on quotes and closing prices from the securities’ local market and may not reflect events that occur subsequent to the local market’s close. Therefore, the intra-day net asset value should not be viewed as a “real-time” update of the NAV, which is computed only once a day. The intra-day net asset value is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities and instruments included in each Fund’s intra-day net asset value basket. Each Fund is not
 
47½Janus Detroit Street Trust

involved in, or responsible for, the calculation or dissemination of the intra-day net asset value and makes no representation or warranty as to its accuracy. An inaccuracy in the intra-day net asset value could result from various factors, including the difficulty of pricing portfolio instruments on an intra-day basis.
Premiums and Discounts
There may be differences between the daily market prices on secondary markets for shares of each Fund and its NAV. NAV is the price per share at which a Fund issues and redeems shares. See “Pricing of Fund Shares” above. The price used to calculate market returns (“Market Price”) of a Fund generally is determined using the midpoint between the highest bid and the lowest offer on the national securities exchange on which shares of the Fund are primarily listed for trading, as of the time that the Fund’s NAV is calculated. A Fund’s Market Price may be at, above, or below its NAV. The NAV of a Fund will fluctuate with changes in the market value of its portfolio holdings. The Market Price of a Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.
Premiums or discounts are the differences (expressed as a percentage) between the NAV and the Market Price of a Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that a Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that a Fund is trading below the reported NAV, expressed as a percentage of the NAV. A discount or premium could be significant. Information regarding a Fund’s premium/discount to NAV for the most recently completed calendar year and the most recently completed calendar quarters since that calendar year end (or the life of the Fund, if shorter) is available at janushenderson.com/performance by selecting the Fund for additional details.
Bid/Ask Spread
Investors purchasing or selling shares of a Fund in the secondary market may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (the “bid”) and the lowest price a seller is willing to accept for shares of the Fund (the “ask”). The spread varies over time for shares of a Fund based on its trading volume and market liquidity, and is generally less if the Fund has more trading volume and market liquidity and more if the Fund has less trading volume and market liquidity. Historical information regarding a Fund’s spread over various periods of time can be accessed at janushenderson.com/performance by selecting the Fund for additional details.
Investments by Other Investment Companies
The Trust and Janus Investment Fund are part of the same “group of investment companies” for purposes of Section 12(d)(1)(G) of the 1940 Act.
Under the 1940 Act, purchases or acquisitions by each Fund of shares issued by registered investment companies (including other ETFs) and business development companies (“BDCs”) and the purchase or acquisition of Fund shares by registered investment companies, BDCs, and investment vehicles 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 where an exemption is available, including as provided in Sections 12(d)(1)(F) and (G) and Rule 12d1-4 thereunder. Rule 12d1-4 permits registered investment companies and BDCs to invest in Fund shares beyond the limits in Section 12(d)(1)(A), subject to certain terms and conditions, including that the registered investment company or BDC first enter into a written agreement with the Trust regarding the terms of the investment, among other conditions.
 
EXCESSIVE TRADING
Unlike traditional mutual funds, the frequent trading of Fund shares generally does not disrupt portfolio management, increase a Fund’s trading costs, lead to realization of capital gains by the Fund, or otherwise harm Fund shareholders. The vast majority of trading in Fund shares occurs on the secondary market. Because these trades do not involve a Fund, they do not harm the Fund or its shareholders. A few institutional investors, referred to as Authorized Participants, are authorized to purchase and redeem Fund shares directly with each Fund in Creation Units. Creation Unit transactions that are effected using securities (i.e., in-kind) do not cause any of the harmful effects to the issuing fund (as previously noted). However, Creation Unit transactions effected using cash can potentially subject the Fund and its shareholders to those harmful effects. As a result, each Fund requires Authorized Participants to pay transaction fees to cover brokerage and certain related costs when purchasing or redeeming Creation Units. Those fees are designed to protect each Fund and its shareholders from the dilutive costs associated with frequent creation and redemption activity. For these reasons, the Trustees of each Fund have determined that it is not necessary to adopt policies and procedures to detect and deter frequent trading and market timing of Fund shares. However, each Fund’s policies and procedures regarding frequent purchases and redemptions may be modified by the Trustees at any time.

FUND WEBSITE & AVAILABILITY OF PORTFOLIO HOLDINGS INFORMATION
Each Business Day, each Fund’s portfolio holdings information is provided by its custodian or other agent for dissemination through the facilities of the NSCC and/or other fee-based subscription services to NSCC members and/or subscribers to entities that publish and/or analyze such information in connection with the process of purchasing or redeeming Creation Units or trading shares of a Fund in the secondary market. In addition, on each Business Day before commencement of trading in shares on the Exchange, each Fund will disclose on janushenderson.com/info the identities and quantities of each portfolio position held by the Fund that will form the basis for the Fund’s next calculation of the NAV. Each Fund is also required to disclose its complete holdings as an exhibit to its reports on Form N-PORT within 60 days of the end of the first and third fiscal quarters, and in the annual report and semiannual report to Fund shareholders.
For additional information on these disclosures and the availability of portfolio holdings information, please refer to the Funds’ SAI.
 
SHAREHOLDER COMMUNICATIONS
Statements and Reports
Your financial intermediary or plan sponsor is responsible for sending you periodic statements of all transactions, along with trade confirmations and tax reporting, as required by applicable law.
Your financial intermediary or plan sponsor is responsible for providing annual and semiannual reports, including the financial statements of each Fund. These reports show each Fund’s investments and the market value of such investments, as well as other information about the Fund and its operations. Please contact your financial intermediary or plan sponsor to obtain these reports. Each Fund’s fiscal year ends October 31.
Lost (Unclaimed/Abandoned) Accounts
It is important to maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned as undeliverable. Based upon statutory requirements for returned mail, your financial intermediary or plan sponsor is required to attempt to locate the shareholder or rightful owner of the account. If the financial intermediary or plan sponsor is unable to locate the shareholder, then the financial intermediary or plan sponsor is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.

GLOSSARY OF INVESTMENT TERMS
 
 
 
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Funds may invest, as well as some general investment terms. The Funds may invest in these instruments to the extent permitted by its investment objective and policies. The Funds are not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
 
EQUITY AND DEBT SECURITIES
Average-Weighted Effective Maturity is a measure of a bond’s maturity. The stated maturity of a bond is the date when the issuer must repay the bond’s entire principal value to an investor. Some types of bonds may also have an “effective maturity” that is shorter than the stated date due to prepayment or call provisions. Securities without prepayment or call provisions generally have an effective maturity equal to their stated maturity. Average-weighted effective maturity is calculated by averaging the effective maturity of bonds held by a Fund with each effective maturity “weighted” according to the percentage of net assets that it represents.
Bank loans include institutionally-traded floating and fixed-rate debt securities generally acquired as a participation interest in or assignment of a loan originated by a lender or financial institution. Assignments and participations involve credit, interest rate, and liquidity risk. Interest rates on floating rate securities adjust with interest rate changes and/or issuer credit quality.
Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.
Commercial paper is a short-term debt obligation with a maturity ranging from 1 to 270 days issued by banks, corporations, and other borrowers to investors seeking to invest idle cash. A Fund may purchase commercial paper issued in private placements under Section 4(2) of the Securities Act of 1933, as amended.
Common stocks are equity securities representing shares of ownership in a company and usually carry voting rights and earn dividends. Unlike preferred stock, dividends on common stock are not fixed but are declared at the discretion of the issuer’s board of directors.
Convertible Bonds are hybrid securities that have characteristics of both bonds and common stocks and are therefore subject to both fixed income security risk and equity security risks. Convertible bonds are similar to other fixed-income securities because they usually pay a fixed interest rate and are obligated to repay principal on a specific future date.
Credit risk transfer securities are unguaranteed and unsecured mortgage related securities issued by a government-related organization or SPV, respectively, and therefore are not directly linked to or backed by the underlying mortgage loans. Unlike mortgage-backed securities, investors in CRT securities issued by a government-related organization have no recourse to the underlying mortgage loans. In addition, some or all of the mortgage default risk associated with the underlying mortgage loans is transferred to the noteholder. Therefore, a Fund could lose all or part of its investments in CRT securities in the event of a default by the underlying mortgages. Refer to “Mortgage and asset backed securities” above.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Duration is a measurement of price sensitivity to interest rate changes. Unlike average maturity, duration reflects both principal and interest payments. Generally, the higher the coupon rate on a bond, the lower its duration will be. The duration of a bond portfolio is calculated by averaging the duration of bonds held by an underlying fund with each duration “weighted” according to the percentage of net assets that it represents. Because duration accounts for interest payments, a Fund’s duration is usually shorter than its average maturity. Securities with longer durations tend to be more sensitive to changes in interest rates, and are usually more volatile than securities with shorter duration. For example, the price of a bond portfolio with an average duration of five years would be expected to fall approximately 5% if interest rates rose by one percentage point. A Fund with a longer portfolio duration is more likely to experience a decrease in its share price as interest rates rise.
Equity securities generally include domestic and foreign common stocks; preferred stocks; securities convertible into common stocks or preferred stocks; warrants to purchase common or preferred stocks; and other securities with equity characteristics.
 
52½Janus Detroit Street Trust

Exchange-traded funds (“ETFs”) are index-based investment companies which hold substantially all of their assets in securities with equity characteristics. As a shareholder of another investment company, a Fund would bear its pro rata portion of the other investment company’s expenses, including advisory fees, in addition to the expenses the Fund bears directly in connection with its own operations.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short- and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
High-yield/high-risk bonds are bonds that are rated below investment grade by the primary rating agencies (i.e., BB+ or lower by Standard & Poor’s and Fitch, or Ba or lower by Moody’s). Other terms commonly used to describe such bonds include “lower rated bonds,” “non-investment grade bonds,” and “junk bonds.”
Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis.
Mortgage dollar rolls are transactions in which a Fund’s sells a mortgage-related security, such as a security issued by Government National Mortgage Association, to a dealer and simultaneously agrees to purchase a similar security (but not the same security) in the future at a predetermined price. A “dollar roll” can be viewed as a collateralized borrowing in which a Fund’s pledges a mortgage-related security to a dealer to obtain cash.
Municipal securities are bonds or notes issued by a U.S. state or political subdivision. A municipal security may be a general obligation backed by the full faith and credit (i.e., the borrowing and taxing power) of a municipality or a revenue obligation paid out of the revenues of a designated project, facility, or revenue source.
Pass-through securities are shares or certificates of interest in a pool of debt obligations that have been repackaged by an intermediary, such as a bank or broker-dealer.
Preferred stocks are equity securities that generally pay dividends at a specified rate and have preference over common stock in the payment of dividends and liquidation. Preferred stock generally does not carry voting rights.
Private placements are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be listed on an exchange and may have no active trading market. As a result of the absence of a public trading market, the prices of these securities may be more volatile and more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies.
Real estate investment trust (“REIT”) is an investment trust that operates through the pooled capital of many investors who buy its shares. Investments are in direct ownership of either income property or mortgage loans. A REIT may be listed on an exchange or traded over-the-counter.
Restricted securities are securities acquired through nonpublic transactions that have limitations on their resale. Restricted securities are unregistered and may only be resold under certain circumstances as noted in Rule 144A of the Securities Act of 1933, as amended.
“To be announced” or “TBA” commitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities, for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate, and mortgage terms. At the time the TBA commitment is made, the transaction is recorded and thereafter the value of such securities is reflected each day in determining a Fund’s NAV. Because a Fund is generally not required to pay for the security until the settlement date, if the Fund remains substantially fully invested at a time when TBA commitment purchases are outstanding, the purchases may result in a form of leverage.
U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year, Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities.
 
53½Janus Detroit Street Trust

Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.
Variable and floating rate securities have variable or floating rates of interest and, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate. The floating rate tends to decrease the security’s price sensitivity to changes in interest rates.
Zero coupon bonds are debt obligations that do not pay regular cash interest payments at regular intervals, but are issued at a discount from face value. The discount approximates the total amount of interest the security will accrue from the date of issuance to maturity. The market value of these securities generally fluctuates more in response to changes in interest rates than interest-paying securities.
 
FUTURES, OPTIONS, AND OTHER DERIVATIVES
Credit default swaps are a specific kind of counterparty agreement that allows the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the credit default swap agrees to insure this risk in exchange for regular periodic payments.
Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset (stock, bond, commodity, currency, interest rate or market index). Types of derivatives can include, but are not limited to options, forward contracts, swaps, and futures contracts.
Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component may be based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or non-registered form. An investment in equity-linked structured notes creates exposure to the credit risk of the issuing financial institution, as well as to the market risk of the underlying securities. There is no guaranteed return of principal with these securities, and the appreciation potential of these securities may be limited by a maximum payment or call right. In certain cases, equity-linked structured notes may be more volatile and less liquid than less complex securities or other types of fixed-income securities. Such securities may exhibit price behavior that does not correlate with other fixed-income securities.
Equity swaps involve the exchange by two parties of future cash flow (e.g., one cash flow based on a referenced interest rate and the other based on the performance of stock or a stock index).
Forward contracts are contracts to purchase or sell a specified amount of a financial instrument for an agreed upon price at a specified time. Forward contracts are not currently exchange-traded and are typically negotiated on an individual basis. A Fund may enter into forward currency contracts for investment purposes or to hedge against declines in the value of securities denominated in, or whose value is tied to, a currency other than the U.S. dollar or to reduce the impact of currency appreciation on purchases of such securities. It may also enter into forward contracts to purchase or sell securities or other financial indices.
Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. A Fund may buy and sell futures contracts on foreign currencies, securities, and financial indices including indices of U.S. Government, foreign government, equity, or fixed-income securities. A Fund may also buy options on futures contracts. An option on a futures contract gives the buyer the right, but not the obligation, to buy or sell a futures contract at a specified price on or before a specified date. Futures contracts and options on futures are standardized and traded on designated exchanges.
Inflation-linked swaps involve the exchange by a Fund with another party of their respective commitments to pay or receive interest (e.g., an exchange of fixed rate payments for floating rate payments or an exchange of floating rate payments based on two different reference indices). By design, one of the reference indices is an inflation index, such as the Consumer Price Index.
 
54½Janus Detroit Street Trust

Interest rate swaps involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments).
Inverse floaters are debt instruments whose interest rate bears an inverse relationship to the interest rate on another instrument or index. For example, upon reset, the interest rate payable on the inverse floater may go down when the underlying index has risen. Certain inverse floaters may have an interest rate reset mechanism that multiplies the effects of change in the underlying index. Such mechanism may increase the volatility of the security’s market value.
Options are the right, but not the obligation, to buy or sell a specified amount of securities or other assets on or before a fixed date at a predetermined price. A Fund may purchase and write put and call options on securities, securities indices, and foreign currencies. A Fund may purchase or write such options individually or in combination.
Total return swaps involve an exchange by two parties in which one party makes payments based on a set rate, either fixed or variable, while the other party makes payments based on the return of an underlying asset, which includes both the income it generates and any capital gains over the payment period. A fixed-income total return swap may be written on many different kinds of underlying reference assets, and may include different indices for various kinds of debt securities (e.g., U.S. investment grade bonds, high-yield bonds, or emerging market bonds).
 
OTHER INVESTMENTS, STRATEGIES, AND/OR TECHNIQUES
Cash sweep program is an arrangement in which a Fund’s uninvested cash balance is used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles that operate pursuant to the provisions of the Investment Company Act of 1940, as amended (the “1940 Act”) that govern the operation of money market funds at the end of each day.
Diversification is a classification given to a fund under the Investment Company Act of 1940, as amended (the “1940 Act”). Funds are classified as either diversified or nondiversified. To be classified as diversified under the 1940 Act, a fund may not, with respect to 75% of its total assets, invest more than 5% of its total assets in any issuer and may not own more than 10% of the outstanding voting securities of an issuer. A fund that is classified as nondiversified under the 1940 Act, on the other hand, has the flexibility to take larger positions in securities than a fund that is classified as diversified. However, because the appreciation or depreciation of a single security may have a greater impact on the NAV of a fund which is classified as nondiversified, its share price can be expected to fluctuate more than a comparable fund which is classified as diversified.
Industry concentration for purposes under the 1940 Act is the investment of 25% or more of a Fund’s total assets in an industry or group of industries.
Leverage is investment exposure which exceeds the initial amount invested. Leverage occurs when a Fund increases its assets available for investment using reverse repurchase agreements, derivatives, or other similar transactions. In addition, other investment techniques, such as short sales, can create a leveraging effect.
Net long is a term used to describe when a Fund’s assets committed to long positions exceed those committed to short positions.
Repatriation is the ability to move liquid financial assets from a foreign country to an investor’s country of origin.
Repurchase agreements involve the purchase of a security by a Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.
Reverse repurchase agreements involve the sale of a security by a Fund to another party (generally a bank or dealer) in return for cash and an agreement by the Fund to buy the security back at a specified price and time. This technique will be used primarily to provide cash to satisfy unusually high redemption requests, or for other temporary or emergency purposes.
When-issued, delayed delivery, and forward commitment transactions generally involve the purchase of a security with payment and delivery at some time in the future – i.e., beyond normal settlement. New issues of stocks and bonds, private placements, and U.S. Government securities may be sold in this manner.
