INVESTMENT OBJECTIVE

Janus Henderson AAA CLO ETF seeks capital preservation and current income by seeking to deliver floating-rate exposure to high quality AAA-rated collateralized loan obligations (“CLOs”).

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	0.25%
Other Expenses	0.00%
Acquired Fund Fees and Expenses(1)	0.01%
Total Annual Fund Operating Expenses	0.26%

(1) Acquired Fund Fees and Expenses are indirect fees and expenses that the Fund incurs from investing in other investment companies. Please note that the amount of Total Annual Fund Operating Expenses shown in the above table may differ from the ratio of gross expenses included in the “Financial Highlights” section of this prospectus, which reflects the operating expenses of the Fund and does not include indirect expenses such as Acquired Fund Fees and Expenses.

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
$	27	$	84	$	146	$	331

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 42% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGY

The Fund pursues its investment objective by investing, under normal circumstances, at least 90% of its net assets (plus any borrowings made for investment purposes) in CLOs of any maturity that are rated AAA (or equivalent by a nationally recognized statistical rating organization (“NRSRO”)) at the time of purchase, or if unrated, determined to be of comparable credit quality by the Adviser. For purposes of the Fund’s investment policies, CLOs are floating- or fixed-rate debt securities issued in different tranches, with varying degrees of risk, by a trust or other special purpose vehicle and backed by an underlying portfolio consisting primarily of below investment grade corporate loans. Such loans may include domestic and foreign senior secured loans, senior unsecured loans and subordinate corporate loans, which may individually be rated below investment grade or the equivalent if unrated. The underlying loans are selected by a CLO’s manager. Under normal market conditions, the Fund will

1_½Janus Henderson AAA CLO ETF

seek to maintain a minimum of 80% of its portfolio in AAA-rated CLOs. After purchase, a CLO may have its rating reduced below the minimum rating required by the Fund for purchase. In such cases, the Fund will consider whether to continue to hold the CLO. The Fund may temporarily deviate from the 80% policy while deploying new capital as the result of cash creation or redemption activity, or during unusual market conditions, or highly unusual market conditions such as a downgrade in the rating of one or more CLOs.

The Fund may invest its remaining assets in other high-quality CLOs with a minimum rating of A- at the time of purchase or if unrated, determined to be of comparable credit quality by the Adviser. No CLO, at the time of purchase by the Fund, will have a rating that is below A- (or equivalent by an NRSRO). 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 will only invest in CLOs with a minimum initial total offering size of $250 million and minimum initial senior AAA tranche size of $100 million.

The Fund will invest primarily in CLOs that are U.S. dollar denominated. However, the Fund may from time to time invest up to 30% of its net assets in CLOs that are denominated in foreign currencies. To the extent the Fund invests in non-U.S. dollar denominated securities, it will seek to hedge its exposure to foreign currency to U.S. dollars, as described more fully below.

The Fund may purchase CLOs both in the primary and secondary markets.

The Fund will not invest more than 5% of its portfolio in any single CLO, and will not invest more than 15% of its portfolio in CLOs managed by a single CLO manager.

The Fund will limit its investment in fixed-rate CLOs to a maximum of 10% of its net assets.

The Fund may invest in derivatives only to hedge or offset risks associated with the Fund’s existing portfolio of CLOs. 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’s use of derivatives will be limited to (i) currency forward contracts or futures contracts to hedge any foreign currency exposure back to the U.S. dollar, and (ii) interest rate swaps or interest rate futures to hedge exposure in fixed-rate CLOs to a floating-rate, in accordance with the Fund’s investment objective. Accordingly, the Fund’s use of derivatives associated with currency hedging will be limited by its maximum exposure of up to 30% of its net assets in CLOs that are denominated in foreign currencies. Derivatives will not be used for any other purposes.

The Fund may invest a portion of its assets in cash or other short-term instruments, such as money market instruments or money market funds, while deploying new capital, for liquidity management purposes, managing redemptions, or for defensive purposes, including navigating unusual market conditions.

The Fund is “actively-managed” and does not seek to replicate the composition or performance of any particular index. Accordingly, the portfolio managers have discretion on a daily basis to manage the Fund’s portfolio in accordance with the Fund’s investment objective. The portfolio managers apply a “bottom up” approach to selecting investments to purchase and sell. This means that the portfolio managers look at securities one at a time to determine if a security is an attractive investment opportunity and if it is consistent with the Fund’s investment policies.

PRINCIPAL INVESTMENT RISKS

Although the Fund may be less volatile than funds that invest most of their assets in common stocks, the Fund’s returns and yields will vary, and you could lose money. The principal risks and special considerations associated with investing in the Fund are set forth below.

CLO Risk.  The risks of investing in CLOs include both the economic risks of the underlying loans combined with the risks associated with the CLO structure governing the priority of payments. The degree of such risk will generally correspond to the specific tranche in which the Fund is invested. The Fund intends to invest primarily in AAA-rated tranches; however, this rating does not constitute a guarantee, may be downgraded, and in stressed market environments it is possible that even senior CLO tranches could experience losses due to actual defaults, increased sensitivity to defaults due to collateral default and the disappearance of the subordinated/equity tranches, market anticipation of defaults, as well as negative market sentiment with respect to CLO securities as an asset class. The Fund’s portfolio managers may not be able to accurately predict how specific

2_½Janus Henderson AAA CLO ETF

CLOs or the portfolio of underlying loans for such CLOs will react to changes or stresses in the market, including changes in interest rates. The most common risks associated with investing in CLOs are liquidity risk, interest rate risk, credit risk, call risk, and the risk of default of the underlying asset, among others.

Debt Securities Risk.  Variable-and floating-rate debt obligations (including CLOs and the portfolio of loans underlying the CLOs), as well as fixed-income debt instruments are subject to the following risks.

• Liquidity Risk. Liquidity risk refers to the possibility that the Fund may not be able to sell or buy a security or close out an investment contract at a favorable price or time. 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. Infrequent trading of securities also may lead to an increase in their price volatility. CLOs, and their underlying loan obligations, are typically not registered for sale to the public and therefore are subject to certain restrictions on transfer and sale, potentially making them less liquid than other types of securities. Additionally, when the Fund purchases a newly issued CLO directly from the issuer (rather than from the secondary market), there often may be a delayed settlement period, during which time the liquidity of the CLO may be further reduced. During periods of limited liquidity and higher price volatility, the Fund’s ability to acquire or dispose of CLOs at a price and time the Fund deems advantageous may be impaired. CLOs are generally considered to be long-term investments and there is no guarantee that an active secondary market will exist or be maintained for any given CLO.

• Interest Rate Risk. As interest rates decrease, issuers of the underlying loan obligations may refinance any floating rate loans, which will result in a reduction in the principal value of the CLO’s portfolio and require the CLO to reinvest cash at an inopportune time. Conversely, as interest rates rise, borrowers with floating rate loans may experience difficulty in making payments, resulting in delinquencies and defaults, which will result in a reduction in cash flow to the CLO and the CLO investors, including the Fund. An increase in interest rates may cause the value of fixed-income securities held by the Fund to decline. The Fund may be subject to a greater risk of rising interest rates due to the current period of historically low rates and the effect of potential government fiscal and monetary policy initiatives and resulting market reaction to those initiatives.

• Floating Rate Obligations Risk. Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction of income received from floating rate securities held by the Fund and may adversely affect the value of the Fund’s shares. Generally, floating rate securities carry lower yields than fixed notes of the same maturity. The interest rate for a floating rate note resets or adjusts periodically by reference to a benchmark interest rate. The impact of interest rate changes on floating rate investments is typically mitigated by the periodic interest rate reset of the investments. Securities with longer durations tend to be more sensitive to interest rate changes, usually making them more volatile than securities with shorter durations. Benchmark interest rates, such as the London Interbank Offered Rate (“LIBOR”), may not accurately track market interest rates.

• Credit Risk. Debt issuers and other counterparties may not honor their obligations or may have their debt downgraded by ratings agencies. Ratings provided by NRSROs represent their opinions of the claims-paying ability of the entities rated by them. Such ratings are general and are not absolute standards of quality. For CLOs, the primary source of credit risk is the ability of the underlying portfolio of loans to generate sufficient cash flow to pay investors on a full and timely basis when principal and/or interest payments are due. Default in payment on the underlying loans will result in less cash flow from the underlying portfolio and, in turn, less funds available to pay investors in the CLO.

• Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security before its stated maturity. CLOs are typically structured such that, after a specified period of time, the majority investor in the equity tranche can call (i.e., redeem) the securities issued by the CLO in full. The Fund may not be able to accurately predict when or which of its CLO investments may be called, resulting in the Fund having to reinvest the proceeds in unfavorable circumstances, which in turn could cause in a decline in the Fund’s income.

• Extension Risk. During periods of rising interest rates, certain debt obligations potentially including the portfolio of loans underlying a CLO will be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in the Fund’s income and potentially in the value of the Fund’s investments.

• Income Risk. The Fund’s income may decline if interest rates fall. This decline in income can occur because most of the CLO debt instruments held by the Fund will have floating or variable interest rates.

3_½Janus Henderson AAA CLO ETF

• Valuation Risk. Valuation Risk is the risk that one or more of the debt 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. The tiered structure of certain CLOs may subject them to price volatility and enhanced liquidity and valuation risk in times of market stress.

• Privately Issued Securities Risk. CLOs are generally privately-issued securities, and are normally purchased pursuant to Rule 144A or Regulation S under the Securities Act of 1933, as amended (the “Securities Act”). Privately-issued securities typically may be resold only to qualified institutional buyers, in a privately negotiated transaction, to a limited number of purchasers, or in limited quantities after they have been held for a specified period of time and other conditions are met for an exemption from registration. Because there may be relatively few potential purchasers for such securities, especially under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Fund may find it more difficult to sell such securities when it may be advisable to do so or it may be able to sell such securities only at prices lower than if such securities were more widely held and traded. At times, it also may be more difficult to determine the fair value of such securities for purposes of computing the Fund’s net asset value per share (“NAV”) due to the absence of an active trading market. There can be no assurance that a privately-issued security previously deemed to be liquid when purchased will continue to be liquid for as long as it is held by the Fund, and its value may decline as a result.

• Covenant Lite Loans Risk. Certain of 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 that would require a borrower to maintain certain financial metrics. A CLO may be delayed in enforcing its interests in covenant lite loans, which may result in losses.

CLO Manager Risk.  CLOs are managed by investment advisers independent of the Adviser. CLO managers are responsible for selecting, managing and replacing the underlying bank loans within a CLO. CLO managers may have limited operating histories, may be subject to conflicts of interests, including managing the assets of other clients or other investment vehicles, or receiving fees that incentivize maximizing the yield, and indirectly the risk, of a CLO. Adverse developments with respect to a CLO manager, such as personnel and resource constraints, regulatory issues or other developments that may impact the ability and/or performance of the CLO manager, may adversely impact the performance of the CLO securities in which the Fund invests.

LIBOR Replacement Risk.  The Fund may invest in certain debt securities, derivatives, or other financial instruments that utilize the London Inter-Bank Offered Rate (“LIBOR”) as a reference rate for various rate calculations. The U.K. Financial Conduct Authority has announced that it intends to stop compelling or inducing banks to submit rates for many LIBOR settings after December 31, 2021, and for certain other commonly-used U.S. dollar LIBOR settings after 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 net asset value. 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.

Foreign Exposure Risk.  The Fund may have exposure to foreign markets as a result of its investments in foreign securities and securities denominated in foreign currencies. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or 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. To the extent the Fund invests in foreign debt securities, such investments are sensitive to changes in interest rates. The 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.

4_½Janus Henderson AAA CLO ETF

Currency Risk.  As long as the Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When the Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency. Although the Fund will seek to hedge any exposure to foreign currency back to US dollars, there is no guarantee such hedging strategies will be effective or have the desired result.

Geographic Investment Risk.  To the extent that the Fund invests a significant portion of its assets in a particular country or geographic region, the Fund will generally have more exposure to certain risks due to possible political, economic, social, or regulatory events in that country or region. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on the Fund’s performance.

Investment Focus Risk.  Because the Fund invests primarily in CLOs it is susceptible to an increased risk of loss due to adverse occurrences in the CLO market, generally, and in the various markets impacting the portfolios of loans underling these CLOs. The Fund’s CLO investment focus may cause the Fund to perform differently than the overall financial market and the Fund’s performance may be more volatile than if the Fund’s investments were more diversified across financial instruments and or markets.

Newly Issued Securities Risk.  The credit obligations in which the 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 the Fund during periods in which it has a small asset base. The impact of new issues on the 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 the 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. The Fund may hold new issues for a short period of time. This may increase the Fund’s portfolio turnover and may lead to increased expenses for the Fund, such as 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.

Extended Settlement Risk.  Newly issued CLOs purchased in the primary market typically experience delayed or extended settlement periods. In the period following such a purchase and prior to settlement these CLOs may be considered less liquid than similar CLOs available in the secondary market. In such circumstances the Fund bears a risk of loss if the value of the CLO declines before the settlement date or if the Fund is required to sell the CLO prior to settlement. There is also the risk that the security will not be issued or that the counterparty will not meet its obligation, resulting in a loss of the investment opportunity.

Market Risk.  The value of the Fund’s portfolio may decrease if the value of an individual security, or multiple securities, in the portfolio decreases. Further, regardless of how well individual securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. 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. 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, social unrest, natural disasters, epidemics and pandemics, including the COVID-19 outbreak) adversely interrupt the global economy and financial markets.

Derivatives Risk.  Derivatives, such as swaps, forwards, and futures 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 and the potential for increased volatility. The Fund may be subject to increased liquidity risk to the extent its derivative positions become illiquid. Derivatives also involve the risk that the counterparty to the derivative transaction will default on its payment obligations. While use of derivatives to hedge can reduce or eliminate losses, it can also 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.

Management Risk.  The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies employed for the Fund may fail to produce the intended results. Although the Fund seeks to provide long-term positive returns, market conditions or implementation of the Fund’s investment process may result in losses, and the Fund may not meet its investment objective. As such, there can be no assurance of positive “absolute” returns.

5_½Janus Henderson AAA CLO 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 price 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:  John Kerschner, CFA, is Co-Portfolio Manager of the Fund, which he has co-managed since inception. Nick Childs, 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 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.

7_½Janus Henderson AAA CLO ETF

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.
