Investment Objective

The GMO International Quality ETF (the "Fund") seeks total return.

Fees and Expenses

The table below describes the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.

Annual Fund Operating Expenses (Expenses that you pay each year as a percentage of the value of your investment)
Management fee			0.60	%
Distribution and service (12b-1) fees			0.00	%
Other expenses			0.00	%
Total annual Fund operating expenses			0.60	%

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 assumes that you invest $10,000 in the Fund for the time periods indicated and then sell or hold 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
$	61			$	192			$	335			$	750

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 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 above, affect the Fund's performance. For the fiscal period October 29, 2024 (commencement of operations) through June 30, 2025, the Fund's portfolio turnover rate was 9% of the average value of its portfolio.

Principal Investment Strategies

The Fund is an actively managed exchange-traded fund ("ETF") that seeks to achieve its investment objective by investing primarily in non-U.S. equities that the Fund's adviser, Grantham, Mayo, Van Otterloo & Co. LLC ("GMO" or the "Adviser"), believes to be of high quality. GMO believes a high quality company generally to be a company that has an established business that will deliver a high level of return on past investments and that will use cash flows to make investments with the potential for a high return on capital or to return cash to shareholders through dividends or share buybacks. Equity securities primarily include common and preferred stocks and, to a lesser extent, other stock-related securities, such as convertible securities, depositary receipts, equity real estate investment trusts ("REITs"), income trusts, and securities of other investment companies that investment primarily in equity securities.

In selecting securities for purchase and sale by the Fund, GMO uses a combination of investment methods, typically considering both (1) systematic factors, based on profitability, profit stability, leverage, and other publicly available financial information, and (2) judgmental factors, based on GMO's assessment of future profitability, capital allocation, growth opportunities, and sustainability against competitive forces. The weight that each systematic and judgmental factor is given for a particular security varies over time and depends on GMO's assessment of the factor's materiality and relevance to that security. GMO also may rely on valuation methodologies, such as discounted cash flow analysis and multiples of price to earnings, revenues, book values or other fundamental metrics with the objective of buying higher quality stocks at a discount to what GMO believes to be their fundamental fair (or intrinsic) value. The Fund is not subject to any limit on the frequency with which portfolio securities may be purchased or sold, and GMO makes investment decisions for the Fund without regard to portfolio turnover rates.

At times, the Fund may have substantial exposure to a single asset class, industry, sector, country, region, issuer, or currency or companies with similar market capitalizations. The Fund may invest in securities of companies of any market capitalization. The Fund may invest in both developed and emerging market securities. The factors GMO considers and investment methods GMO uses can change over time. GMO does not manage the Fund to, or control the Fund's risk relative to, any securities index or securities benchmark.

The Fund also may invest in the GMO U.S. Treasury Fund, a mutual fund advised by GMO, or in money market funds unaffiliated with GMO, and directly in the types of investments typically held by money market funds.

Principal Risks of Investing in the Fund

The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly. Many factors can affect this value, and you may lose money by investing in the Fund or your investment in the Fund could underperform other investments. The Fund is a non-diversified investment company under the Investment Company Act of 1940, as amended, and therefore a decline in the market price of a particular security held by the Fund may affect the Fund's performance more than if the Fund were a diversified investment company. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any government agency. The principal risks of investing in the Fund are summarized below and are all considered a "principal risk of investing in the Fund regardless of the order in which it appears. For a more complete discussion of these risks, see "Additional Principal Risk Information."

●

Market Risk - Equities - The market price of an equity in the Fund's portfolio may decline due to factors affecting the issuer or its industry or the economy and equity markets generally. If the Fund purchases an equity for less than its fundamental fair (or intrinsic) value as assessed by GMO, the Fund runs the risk that the market price of the equity will not appreciate or will decline (for example, if GMO's assessment proves to be incorrect or the market fails to recognize the equity's intrinsic value). The Fund also may purchase equities that typically trade at higher multiples of current earnings than other securities, and the market prices of these equities often are more sensitive to changes in future earnings expectations and interest rates than the market prices of equities trading at lower multiples. Declines in stock market prices generally are likely to reduce the net asset value of the Fund's shares.

●

Management and Operational Risk - The Fund runs the risk that GMO's investment techniques will fail to produce intended results. GMO uses quantitative models as part of its investment process. GMO's models may not accurately predict future market movements. In addition, GMO's models rely on assumptions and data that are subject to limitations (e.g., inaccuracies, staleness) that could adversely affect their predictive value. The Fund also runs the risk that GMO's assessment of an investment, including a security's fundamental fair (or intrinsic) value, is wrong or that deficiencies in GMO's or another service provider's internal systems or controls will cause losses for the Fund or impair Fund operations.

●

Non-U.S. Investment Risk - The market prices of many non-U.S. securities fluctuate more than those of U.S. securities. Many non-U.S. securities markets are less stable, smaller, less liquid, and less regulated than U.S. securities markets, and the cost of trading in those markets often is higher than in U.S. securities markets. In addition, non-U.S. securities issuers often are not subject to as much regulation as U.S. issuers, and the reporting, recordkeeping, accounting, custody, and auditing standards to which those issuers are subject often are not as rigorous as U.S. standards. In addition, the Fund is subject to taxation by countries other than the United States, including potentially on a retroactive basis, on (i) capital gains it realizes or dividends, interest, or other amounts it realizes or accrues in respect of non-U.S. investments; (ii) transactions in those investments; and (iii) repatriation of proceeds generated from the sale or other disposition of those investments. Also, the Fund needs a license to invest directly in securities traded in many non-U.S. securities markets, and the Fund is subject to the risk that its license is terminated or suspended. In some non-U.S. securities markets, prevailing custody and trade settlement practices (e.g., the requirement to pay for securities prior to receipt) expose the Fund to credit and other risks. Further, adverse changes in investment regulations, capital requirements or exchange controls could adversely affect the value of the Fund's investments. The risks above (such as substantial price fluctuations and market instability, illiquidity and lack of regulation) and other risks (e.g., nationalization, expropriation or other confiscation of assets of non-U.S. issuers, difficulties enforcing legal judgments or contractual rights and geopolitical risks) tend to be higher for investments in the securities of issuers tied economically to emerging countries. The economies of emerging countries often depend predominantly on only a few industries or commodities and often are more volatile than the economies of developed countries.

●

Focused Investment Risk - Investments in countries, regions, asset classes, sectors, industries, currencies, or issuers that are subject to the same or similar risk factors and investments whose market prices are closely correlated are subject to higher overall risk than investments that are more diversified or whose market prices are not as closely correlated.

●

ETF Risks - The Fund is an ETF and, as a result of this structure, is exposed to the following risks:

o

Costs of Buying or Selling Shares Risk. Due to the costs of buying or selling Fund shares, including brokerage commissions imposed by brokers and the variance in bid-ask spreads, frequent trading of Fund shares may significantly reduce investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

o

Limited Authorized Participants, Market Makers and Liquidity Providers Risk. Because the Fund is an ETF, typically only a limited number of institutional investors (known as "Authorized Participants") are authorized to purchase and redeem shares directly from the Fund. Retail investors cannot transact directly with the Fund. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace to transact in Fund shares, there may be demand for Fund shares thereby increasing the market price above NAV, or lack of demand, which may decrease the market price below NAV, or in stressed market conditions, the market for Fund shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings. As a result of these considerations, Fund shares may trade at a material premium or discount to net asset value ("NAV") or these factors may, in turn, lead to wider spreads between the bid and ask price of Fund shares. In addition, the Fund may face possible delisting if: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

o

Trading Risk. Shares of the Fund may trade on the NYSE Arca, Inc. (the "Exchange") above (premium) or below (discount) their NAV. In stressed market conditions, the market for Fund shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may increase the variance between the market price of the Fund shares and the value of its underlying holdings. This can be reflected as a spread between the bid and ask prices for the Fund shares quoted during the day or a premium or discount in the closing price from the Fund's NAV. In addition, although the Fund's shares are currently listed on the Exchange, there can be no assurance that an active trading market for Fund 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 of the Fund inadvisable.

o

Cash Transactions Risk. The Fund may effect some of its creations and redemptions for cash, rather than in-kind securities. As a result, the Fund may have to sell portfolio securities at inopportune times in order to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. The use of cash creations and redemptions may also cause the Fund's shares to trade in the market at wider bid-ask spreads or greater premiums or discounts to the Fund's NAV. In effecting creations and redemptions in exchange for cash, the Fund may incur certain costs, including brokerage costs in connection with investing cash received and may recognize capital gains in connection with cash redemptions, unlike an ETF that effects creations and redemptions only in-kind. In addition, costs could be imposed on the Fund which would have the effect of decreasing the Fund's NAV to the extent the costs are not offset by a transaction fee payable by an Authorized Participant.

o

National Closed Market Trading Risk. To the extent that the underlying securities or other instruments held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund's shares trade is open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., the Fund's quote from the closed foreign market). The impact of a closed foreign market on the Fund is likely to be greater where a large portion of the Fund's underlying securities or other instruments trade on that closed foreign market or when the foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund's NAV that may be greater than those experienced by other ETFs.

●

Smaller Company Risk - Smaller companies may have limited product lines, markets, or financial resources, lack the competitive strength of larger companies, have less experienced managers or depend on a few key employees. The securities of companies with smaller market capitalizations often are less widely held and trade less frequently and in lesser quantities, and their market prices often fluctuate more, than the securities of companies with larger market capitalizations.

●

Market Disruption and Geopolitical Risk -  Geopolitical and other events (e.g., wars, pandemics, sanctions, terrorism) often disrupt securities markets and adversely affect the general economy or particular economies and markets. Those events, as well as other changes in non-U.S. and U.S. economic and political conditions, could exacerbate other risks or otherwise reduce the value of the Fund's investments.

●

Fund of Funds Risk -  The Fund is indirectly exposed to all of the risks of an investment in the underlying funds in which it invests, including the risk that those underlying funds will not perform as expected. In addition, the Fund indirectly bears its pro rata portion of an underlying fund's fees and expenses in addition to the fees and expenses borne by the Fund. As a result, shareholders will be subject to two layers of fees and expenses when the Fund invests in underlying funds.

●

Currency Risk - Fluctuations in exchange rates can adversely affect the market value of the Fund's foreign currency holdings and investments denominated in foreign currencies.

●

New/Smaller Fund Risk - A new or smaller fund is subject to the risk that its performance may not represent how the fund is expected to or may perform in the long term. In addition, new funds have limited operating histories for investors to evaluate and new and smaller funds may not attract sufficient assets to achieve investment and trading efficiencies. There can be no assurance that the Fund will achieve an economically viable size, in which case it could ultimately liquidate.

For important information about the purchase and sale of shares of the Fund, taxes, and financial intermediary compensation please turn to "Summary Information About Purchasing and Selling Shares, Taxes, and Financial Intermediary Compensation" on page 40 of the Prospectus.

Purchase and Sale of Fund Shares

The Fund issues shares to, and redeems shares from, certain institutional investors known as "Authorized Participants" (typically market makers or other broker-dealers) only in large blocks of Fund shares known as "Creation Units." Creation Unit transactions are generally conducted in exchange for the deposit or delivery of a portfolio of in-kind securities designated by the Fund, cash or a combination of securities and cash.

Individual Fund shares may only be purchased and sold in the secondary market through a broker or dealer at a market price. Because Fund shares trade at market prices rather than at NAV, Fund shares may trade at a price greater than NAV (premium) or less than NAV (discount). When buying or selling shares in the secondary market, you 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) (the "bid-ask spread"). When available, recent information regarding the Fund's NAV, market price, premiums and discounts, and bid-ask spreads will be available at https://www.gmo.com/americas/investment-capabilities/etfs.

U.S. Tax Information

The Fund intends to elect to be treated, and intends to qualify and be treated each year, as a regulated investment company (a "RIC") under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") for U.S. federal income tax purposes and to distribute net investment income and net realized capital gains, if any, to shareholders.

Distributions made by the Fund may be taxable as ordinary income, qualified dividend income (if applicable), or long-term capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or individual retirement account. In that case, you may be taxed when you take a distribution from such account, depending on the type of account, the circumstances of your distribution, and other factors.

Payments to Broker-Dealers and Other Financial Intermediaries

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