What is the goal of the Fund?

The Fund seeks investment results that closely correspond, before fees and expenses, to the performance of the Bloomberg Barclays Short-Term U.S. Aggregate Bond Index.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund. Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

ANNUAL FUND OPERATING EXPENSES (Expenses that you pay each year as a percentage of the value of your investment)
Management Fees	0.05	%
Other Expenses	NONE
Total Annual Fund Operating Expenses1	0.05	%

1 The Fund’s management agreement provides that the adviser will pay substantially all expenses of the Fund, except for the management fees, payments under the Fund’s 12b-1 plan (if any), interest expenses, dividend and interest expenses related to short sales, taxes, acquired fund fees and expenses (other than fees for funds advised by the adviser and/or its affiliates), costs of holding shareholder meetings, and litigation and potential litigation and other extraordinary expenses not incurred in the ordinary course of the Fund’s business. The Fund shall be responsible for its non-operating expenses, including brokerage commissions and fees and expenses associated with the Fund’s securities lending program, if applicable.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE
	1 Year		3 Years
SHARES ($)		5		16

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 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. The Fund has not yet commenced operations as of the date of this prospectus. Therefore, there is no portfolio turnover rate for the Fund to report at this time.

What are the Fund’s main investment strategies?

The Fund seeks investment results that closely correspond, before fees and expenses, to the performance of the Bloomberg Barclays Short-Term U.S. Aggregate Bond Index (the “Underlying Index”), which measures the performance of U.S. dollar denominated investment grade taxable bonds with remaining effective maturities between one and five years. The Fund will invest at least 80% of its Assets in securities included in the Underlying Index. “Assets” means net assets, plus the amount of borrowing for investment purposes. Bloomberg Index Services Limited is the index provider for the Underlying Index (the “Index Provider”). The Underlying Index is a subset of the Bloomberg Barclays U.S. Aggregate Index and primarily includes U.S. Treasury bonds, government-related bonds (i.e., U.S. and non-U.S. agencies, sovereign, quasi-sovereign, supranational and local authority debt), investment-grade U.S. corporate bonds, mortgage-backed pass-through securities (MBS), commercial mortgage-backed securities, and asset-backed securities. The Underlying Index’s exposure to mortgages is limited to mortgages with maturities of up to 15 years. The dollar-weighted average maturity of the Underlying Index as of January 31, 2019 was 2.9 years.

Beta is a measure of the volatility of a security or a portfolio relative to a market benchmark. The term “BetaBuilders” in the Fund’s name conveys the intended outcome of providing investors with passive exposure and return that generally correspond to a market cap weighted benchmark. The Fund, along with other JPMorgan BetaBuilders Funds, can be used to help an investor build a portfolio of passive exposure to various markets.

The Fund, using a “passive” or indexing investment approach, attempts to closely correspond to the performance of the Underlying Index. J.P. Morgan Investment Management Inc. (JPMIM or the adviser) expects that, over time, the correlation between the Fund’s performance before fees and expenses and that of the Underlying Index will be 95% or better. A figure of 100% would indicate perfect correlation. Unlike many actively-managed funds, the Fund does not seek to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

2

The Fund intends to utilize a “representative sampling” strategy whereby securities are chosen in order to attempt to approximate the investment characteristics of the constituent securities. Targeted investment characteristics of the collective portfolio include asset class exposure, industry weightings, liquidity, and other fixed income specific attributes (such as yield, duration, credit quality, spread and maturity). Even when the Fund utilizes representative sampling, it must still invest at least 80% of its Assets in securities included in the Underlying Index. The Fund’s portfolio will be rebalanced monthly in accordance with the monthly rebalancing of the Underlying Index.

The Fund may invest in mortgage pass-through securities eligible to be sold in the “to-be-announced” or TBA market (Mortgage TBAs). Mortgage TBAs provide for the forward or delayed delivery of the underlying instrument with settlement up to 180 days. The term TBA comes from the fact that the actual mortgage-backed security that will be delivered to fulfill a TBA trade is not designated at the time the trade is made, but rather is announced 48 hours before the settlement date. The Fund may enter into such contracts on a regular basis. The Fund, pending settlement of such contracts, will invest its assets in high-quality, liquid short-term instruments, including shares of money market funds advised by JPMIM or its affiliates.

The Fund will not invest in asset classes that are not present in the Underlying Index. The Fund will not invest in debt securities that are rated below investment grade (i.e., high yield and junk bonds). The Fund may invest in privately placed, restricted and unregistered securities.

To the extent that the securities in the Underlying Index are concentrated in one or more industries or groups of industries, the Fund may concentrate in such industries or groups of industries.

The Fund may also invest in shares of affiliated money market funds.

The Fund’s Main Investment Risks

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s net asset value (NAV), market price, performance and ability to meet its investment objective.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Index Related Risk. The Fund’s return may not track the return of the Underlying Index for a number of reasons and therefore may not achieve its investment objective. For example, the Fund incurs a number of operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the Fund’s return may differ from the return of the Underlying Index as a result of, among other things, pricing differences between the valuation of securities in the Underlying Index and in the Fund’s NAV and the inability to purchase certain securities included in the Underlying Index due to regulatory or other restrictions.

In addition, because the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Underlying Index as when the Fund purchases all of the securities in the Underlying Index in the proportions in which they are represented in the Underlying Index.

Errors in the construction or calculation of the Underlying Index may occur from time to time. Any such errors may not be identified and corrected by the Index Provider for some period of time, which may have an adverse impact on the Fund and its shareholders.

The risk that the Fund may not track the performance of the Underlying Index may be heightened during times of increased market volatility or other unusual market conditions.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not generally sell a security because the security’s issuer was in financial trouble unless that security is removed from the Underlying Index. Therefore, the Fund’s performance could be lower than funds that may actively shift their portfolio assets to take advantage of market opportunities or lessen the impact of a market decline or a decline in the value of one or more issuers. The Fund will not take defensive positions under any market conditions, including in declining markets.

3

Sampling Risk. Because the Fund uses a representative sampling approach, it will hold a smaller number of securities than are in the Underlying Index. As a result, an adverse development respecting an issuer of securities held by the Fund could result in a greater decline in the Fund’s NAV than would be the case if the Fund held all of the securities in the Underlying Index. Conversely, a positive development relating to an issuer of securities in the Underlying Index that is not held by the Fund could cause the Fund to underperform the Underlying Index. To the extent the assets in the Fund are smaller, these risks may be greater.

Concentration Risk. To the extent that the securities in the Underlying Index are concentrated in one or more industries or groups of industries, the Fund may concentrate in such industries or groups of industries. This concentration increases the risk of loss to the Fund by increasing its exposure to economic, business, political or regulatory developments that may be adverse to a particular industry or group of industries.

Interest Rate Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Given that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. If an issuer’s or counterparty’s financial condition worsens, the credit quality of the issuer or counterparty may deteriorate, making it difficult for the Fund to sell such investments.

Geographic Focus Risk. The Fund focuses its investments in the United States. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.

Prepayment Risk. The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

Asset-Backed, Mortgage-Related and Mortgage-Backed Securities Risk. The Fund may invest in asset-backed, mortgage-related and mortgage-backed securities that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities

with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

Privately Placed Securities Risk. Privately placed securities generally are less liquid than publicly traded securities and the Fund may not always be able to sell such securities without experiencing delays in finding buyers or reducing the sale price for such securities. The disposition of some of the securities held by the Fund may be restricted under federal securities laws. As a result, the Fund may not be able to dispose of such investments at a time when, or at a price at which, it desires to do so and may have to bear expenses of registering these securities, if necessary. These securities may also be difficult to value.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other

4

events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the Fund’s Share values may fluctuate in response to events affecting that industry or sector.

ETF Shares Trading Risk. Shares are listed for trading on the Cboe BZX Exchange, Inc. (the “Exchange”) and are bought and sold in the secondary market at market prices. The market prices of Shares are expected to fluctuate, in some cases materially, in response to changes in the Fund’s NAV, the intraday value of the Fund’s holdings and supply and demand for Shares. The adviser cannot predict whether Shares will trade above, below or at their NAV. Disruptions to creations and redemptions, the existence of significant market volatility or potential lack of an active trading market for the Shares (including through a trading halt), as well as other factors, may result in the Shares trading significantly above (at a premium) or below (at a discount) to NAV or to the intraday value of the Fund’s holdings. During such periods, you may incur significant losses if you sell your Shares.

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, fixing or settlement times, bid-ask spreads on the Exchange and the corresponding premium or discount to the Shares’ NAV may widen.

Authorized Participant Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of intermediaries that act as authorized participants and none of these authorized participants is or will be obligated to engage in creation or redemption transactions. To the extent that these intermediaries exit the business or are unable to or choose not to proceed with creation and/or redemption orders with respect to the Fund and no other authorized participant creates or redeems, Shares may trade at a discount to NAV and possibly face trading halts and/or delisting.

Cash Transactions Risk. Unlike certain ETFs, the Fund may effect creations and redemptions in cash or partially in cash. Therefore, it may be required to sell portfolio securities and subsequently recognize gains on such sales that the Fund might not have recognized if it were to distribute portfolio securities in-kind. As such, investments in Shares may be less tax-efficient than an investment in an ETF that distributes portfolio securities entirely in-kind.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

The Fund’s Past Performance

The Fund has not commenced operations as of the date of this prospectus and therefore, has no reportable performance history. Once the Fund has operated for at least one calendar year, a bar chart and performance table will be included in the prospectus to show the performance of the Fund. When such information is included, this section will provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance history from year to year and showing how the Fund’s average annual total returns compare with those of a broad measure of market performance. Although past performance of the Fund is no guarantee of how it will perform in the future, historical performance may give you some indication of the risks of investing in the Fund.

Eric Isenberg	2019	Executive Director
Naveen Kumar	2019	Vice President
Charles Su	2019	Associate
Behnood Noei	2019	Vice President

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only in a large specified number of Shares called a “Creation Unit” or multiples thereof. A Creation Unit consists of 50,000 Shares. The Fund generally issues and redeems Creation Units in return for a designated portfolio of securities and an amount of cash. Except when aggregated in Creation Units, Shares are not redeemable securities of the Fund. Individual Shares of the Fund may only be purchased and sold in secondary market transactions through brokers or financial intermediaries. Shares of the Fund are listed for trading on the Exchange, and because Shares trade at market prices rather than NAV, Shares of the Fund may trade at a price greater than or less than NAV. Certain affiliates of the Fund and

5

the adviser may purchase and resell Shares pursuant to this prospectus.

Tax Information

To the extent the Fund makes distributions, those distributions will be taxed as ordinary income or capital gains, except when your investment is in an IRA, 401(k) plan or other tax-advantaged investment plan, in which case you may be subject to federal income tax upon withdrawal from the tax-advantaged investment plan.

Payments to Broker-Dealers and Other Financial Intermediaries

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