Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Retail Class shares of the Fund for the time periods indicated and then redeem 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 total annual operating expenses remain the same. This Example reflects the net operating expenses with expense waivers for the one-year contractual period and the total operating expenses without expense waivers for years two through ten.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:	One Year	Three Years	Five Years	Ten Years
Retail Class	$101	$373	$666	$1,499

Your expenses would be the same if you did not redeem your shares.

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. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund's performance. A higher turnover rate may also result in higher taxes when Fund shares are held in a taxable account. The Fund is the successor to the Barrett Opportunity Fund, Inc., (the "Predecessor Fund"), an unaffiliated registered investment company. Effective December 31, 2023, the Fund changed its fiscal year end from August 31^st to December 31 ^st. For the fiscal period ended December 31, 2023, the Fund's portfolio turnover rate was 0% of the average value of its portfolio.

Principal Investment Strategies of the Fund

●	The Fund invests primarily in common stocks.

●	While the Adviser evaluates companies of all sizes, the Fund intends to invest primarily in companies with medium market capitalizations ($2 billion to $15 billion) and large market capitalizations (greater than $15 billion).

●	The Fund is classified as "non-diversified," which means it may invest a larger percentage of its assets in a small number of issuers than a diversified fund.

●	The Adviser seeks to identify those companies whose securities are undervalued based on the Adviser's judgment of the company's sustainable earnings growth. The Adviser employs fundamental analysis to analyze each company in detail, ranking the management, strategy and competitive market position.

●	In selecting individual companies for investment, the Adviser considers how the following would affect a company's earnings, the market price of its shares and the market's evaluation of the company's future earnings:

○	Changes in management, policies, corporate control or capitalization;

○	Changes in technology, marketing or production, the development of new products or services or the demand for existing products or services;

○	The effect of recent and anticipated capital expenditures; and

○	The effect of social, economic, political, legal and international developments.

●	The Fund may invest without limit in securities of issuers located in the United States, as well as other securities that are publicly traded in the United States, including sponsored American Depositary Receipts.

●	The Adviser emphasizes individual security selection while varying the Fund's investments across industries, which may help to reduce risk.

●	Stocks may be sold when conditions have changed and the company's prospects are no longer attractive, its stock price has achieved the team's valuation target or better relative investment opportunities have been identified.

Principal Risks of Investing in the Fund

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Fund is set forth below. Before you decide whether to invest in the Fund, carefully consider these risk factors associated with investing in the Fund, which may cause investors to lose money. There can be no assurance that the Fund will achieve its investment objective.

●

Market Risk: As with any fund, the value of your investment will fluctuate over time in response to overall movements in the stock market. Further, investments in common stocks tend to be more volatile than many other investment choices. The value of a security or other asset may decline due to changes in general market conditions, economic trends or events that are not specifically related to the issuer of the security or other asset, or factors that affect a particular issuer or issuers, country, group of countries, region, market industry, group of industries, sector or asset class. Local, regional, or global events such as war, acts of terrorism, the spread of infections, illness or other public health issues, recessions, or other events could have a significant impact on the Fund and its investments. During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates generally do not have the same impact on all types of securities and instruments.

●

Equity Securities Risk: Investments in common stocks and other equity securities are particularly subject to the risk of changing economic, stock market, industry and company conditions and the risks inherent in the ability to anticipate such changes that can adversely affect the value of portfolio holdings. Preferred stock is subject to the risk that the dividend on the stock may be changed or omitted by the issuer and that participation in the growth of an issuer may be limited.

●

Issuer Risk: The value of a security can go up or down more than the market as a whole and can perform differently from the value of the market as a whole, often due to events such as (but not limited to) disappointing earnings reports by the issuer, unsuccessful products or services, loss of major customers, major litigation against the issuer or changes in government regulations affecting the issuer or the competitive environment. The Fund may experience a substantial or complete loss on an individual security. Historically, the prices of securities of small- and medium-capitalization companies have generally gone up or down more than those of large capitalization companies because, among other things, small- and medium-capitalization companies may be more sensitive to changing economic conditions and tend to be less established than large capitalization companies, although even large capitalization companies may fall out of favor with investors.

●

Medium-Sized Company Risk: The medium-sized companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, these medium-sized companies may pose additional risks, including liquidity risk, because these companies tend to have limited product lines, markets, and financial resources, and may depend upon a relatively small management group. Medium-sized companies may be more thinly traded than larger, more established companies. The Fund is subject to the risk that the securities held by the Fund will underperform other securities and/or may decline in value.

●

Large Capitalization Company Risk: Historically, the prices of securities of small- and medium-capitalization companies have generally fluctuated more than those of large capitalization companies because, among other things, small- and medium-capitalization companies may be more sensitive to changing economic conditions and tend to be less established, however, large capitalization companies may fall out of favor with investors.

●	Portfolio Management Risk: The Fund is subject to the risk that the securities held by the Fund will underperform other securities and/or may decline in value.

●

Value Investing Risk: The value approach carries the risk that the market will not recognize a security's intrinsic value for a long time, or that a stock considered to be undervalued may actually be appropriately priced. A portfolio may underperform other equity portfolios that use different investing styles. A portfolio may also underperform other equity portfolios using the value style. Value stocks as a group may be out of favor and underperform the overall equity market for a long period of time, for example, while the market favors "growth" stocks.

●

Net Unrealized Appreciation Risk: The Fund has a substantial amount of net unrealized appreciation. Subject to market conditions and Fund performance, the Adviser anticipates that, in managing the Fund's investment portfolio in pursuit of the Fund's investment objectives, a moderate portion of the Fund's current built-in long-term capital gains will be realized gradually in each of the next several years. If these long-term capital gains are realized as anticipated, this will result in an increase in the Fund's annual distributions of net capital gains and, accordingly, will generally result in taxable distributions to shareholders (other than certain shareholders that are exempt from tax on such income). Under normal market conditions, the Adviser currently expects, but does not guarantee, that no more than 15% of the total amount of the Fund's current built-in long-term capital gains will be realized in any one year. This expectation may change over the course of the year for a variety of reasons including, but not limited to, individual holdings, market events and changes in tax laws. See "Dividends, Distributions and Taxes."

BARRETT OPPORTUNITY FUND

●

Non-diversification Risk: The Fund is classified as "non-diversified," which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund. To the extent the Fund invests its assets in fewer issuers, the Fund will be more susceptible to negative events affecting those issuers.

●

Indirect Foreign Exposure Risk: Investments in U.S.-traded securities that are organized under the laws of a foreign country or have significant business operations abroad may be impacted by certain foreign exposure risks indirectly. This includes securities in the form of sponsored and unsponsored depositary receipts. Unsponsored depositary receipts may be created without the participation of the foreign issuer. Holders of these depositary receipts generally bear all of the costs of the depositary facility and the bank or trust company depositary of an unsponsored depositary receipt may be under no obligation to distribute shareholder communications from the foreign issuer or to pass through voting rights. These risks will vary from time to time and from country to country especially if the country is considered an emerging market or developing country.

●

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. Under an unsponsored ADR arrangement, the foreign issuer assumes no obligations and the Depository's transaction fees are paid directly by the ADR holders. Because unsponsored ADR arrangements are organized independently and without the cooperation of the issuer of the underlying securities, available information concerning the foreign issuer may not be as current as for sponsored ADRs and voting rights with respect to the deposited securities are not passed through. GDRs can involve additional currency risk since, unlike ADRs, they may not be U.S. Dollar-denominated.

●

Cybersecurity Risk: With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund's ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.
