Example

The following 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 redeem all of your shares at the end of those periods, that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The example also assumes that the contractual fee waiver and/or expense reimbursement is only in effect through October 31, 2027. 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
Class Z	$87	$2,116	$4,617	$9,017

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 period (since the Fund's commencement of operations on June 30,2025 through October 31, 2025), the Fund's portfolio turnover rate was 26.07% of the average value of its portfolio.

Principal Investment Strategy

The Fund is sub-advised by Redwood Investments, LLC ("Redwood"), an affiliate of the Manager (Redwood and the Manager are collectively referred to as the "Manager," where applicable). Subject to the general supervision by the Fund's Board of Trustees, the Manager oversees Redwood and evaluates its performance results. The Manager reviews portfolio performance, compliance with investment guidelines and federal securities laws, and changes in key personnel of Redwood. Redwood is primarily responsible for the day-to-day management of the Fund's portfolio, including purchases and sales of individual securities.

Redwood employs a fundamental investment process that seeks companies it believes are: (1) high quality, (2) attractively valued, and (3) where Redwood believes that future earnings and free cash flow growth will be meaningfully above market expectations. High quality companies are those companies that Redwood believes offer durable competitive advantages, capable management teams, and prudent financial management. Redwood focuses on understanding industry and company dynamics to assess company quality, and on identifying and forecasting critical drivers to reach a differentiated view of future growth.

The Fund invests primarily in equity securities of international small cap companies. Additionally, under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities, including common stocks, American Depositary Receipts and Global Depositary Receipts, of small cap companies. International companies are companies generally defined by a third party, or in certain circumstances by the Manager, (i) that are organized under the laws of a foreign country; (ii) whose securities are primarily listed in a foreign country; (iii) that have a majority of their assets, or derive more than 50% of their revenue or profits from businesses, investments, or sales, outside the United States; or (iv) that are included in the MSCI World ex-USA Small Cap Index. The Fund normally focuses its international investments in developed countries, but may also invest in emerging market countries. The Fund always invests in at least three non-U.S. countries. Small cap companies are companies that, at the time of purchase of the securities, have a total market capitalization in the range of (i) companies included in the MSCI World ex-USA Small Cap Index, or (ii) $500 million to $8 billion. Because small cap companies are defined, in part, by reference to an index, the range of market capitalization of companies in which the Fund invests may vary with market conditions. At December 31, 2025, the market capitalization of the companies in the MSCI World ex-USA Small Cap Index ranged from $348 million to $17.1 billion.

The Fund generally holds approximately 50 holdings. Fund holdings may differ from this number for a variety of reasons, including, among others, because of extreme market volatility, such as when the Fund has entered a temporary defensive position. Additionally, the Fund may exceed the stated number of holdings when it acquires a new holding and determines that it is in the best interests of shareholders to sell an existing holding over a period of time, instead of immediately selling the entire holding.

The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.

The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including, but not limited to, the industrials, financials, consumer discretionary, and information technology sectors. For the purpose of categorizing companies, sectors are a broader category than industries and industries comprise sectors.

The Fund may invest in cash (and cash equivalents) when the Fund is unable to find enough attractive long-term investments to meet its investment objective, to meet redemptions and/or when the Manager believes it is advisable to do so during times of short-term market volatility. During these times, cash (and cash equivalents) will not exceed 15% of the Fund's net assets.

Principal Risks

An investment in the Fund involves risks. The Fund's share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a summary description of principal risks involved in investing in the Fund.

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

Market Risk - Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any

point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, trade disputes and changes in trade regulations, civil unrest, recessions, or other events could have a significant impact on the Fund and its investments.

Equity Securities Risk - As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund's price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund's investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds.

Growth Securities Risk - Prices of growth stocks tend to be higher in relation to their companies' earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment's value.

Foreign Securities Risk - The Fund's performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards. Additionally, events and evolving conditions in certain markets or regions may alter the risk profile of investments tied to those markets or regions. This may cause investments tied to such markets or regions to become riskier or more volatile, even when investments in such markets or regions were perceived as comparatively stable historically. In addition, foreign companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which may decrease the liquidity and value of the securities.

Small Cap Securities Risk - There may be greater risk in investing in companies with small market capitalizations rather than larger, more established companies owing to such factors as more limited product lines or financial resources or lack of management depth. It may also be difficult or impossible to liquidate a security position at a time and price acceptable to the Fund because of the potentially less frequent trading of stocks of smaller market capitalization.

Small Number of Holdings Risk - Under normal circumstances, the Fund invests in a small number of issuers. Therefore, the Fund's performance may be more vulnerable to changes in the market value of a single issuer and more susceptible to risks associated with a single economic, political, or regulatory occurrence than a fund that has a higher number of holdings.

Sector Risk - The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector, as defined by third party sources. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility.

information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies' securities may fall or fail to rise. Many technology related companies' securities have historically been more volatile than other securities, especially over the short term.

Emerging Markets Risk - The Fund may invest in issuers located in emerging markets, and therefore may be exposed to the economies, industries, securities and currency markets of such countries, which may be adversely affected by protectionist trade policies, a slow U.S. economy, political and social instability, regional and global conflicts, terrorism and war, including actions that are contrary to the interests of the United States. Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets. The Fund, individually or in combination with other shareholders, may have limited rights and remedies against emerging market issuers.

ADR and GDR Risk - ADRs and GDRs may be subject to some of the same risks as direct investment in foreign companies, which includes international trade, currency, political, regulatory and diplomatic risks. In a sponsored ADR arrangement, the foreign issuer assumes the obligation to pay some or all of the depository's transaction fees. Unsponsored ADRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends. GDRs can involve additional currency risk since, unlike ADRs, they may not be U.S. Dollar-denominated.

Affiliate Ownership Risk - Certain shareholders, including other funds advised by the Manager or an affiliate of the Manager, may from time to time own a substantial amount of the shares of the Fund. In addition, a third party investor, the Manager or an affiliate of the Manager, or another entity may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund's achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment or that the size of the Fund would be maintained at such levels. Accordingly, the Fund can be subject to the potential for large scale inflows and outflows as a result of purchases and redemptions made by large shareholders. Redemptions by large shareholders could have a significant negative impact on the Fund. Inflows and outflows could be significant, could cause the Fund to sell securities at inopportune times in order to meet redemption requests, and could cause the Fund's portfolio turnover rate and transaction costs to rise, which may negatively affect the Fund's performance and have adverse tax consequences for Fund shareholders.

Cash Position Risk - At times, the Fund may hold up to 15% of its net assets in cash (and cash equivalents), which may underperform relative to equity securities.
