The Boston Trust Midcap Fund seeks long-term capital growth through an actively managed portfolio of stocks of middle capitalization ("mid cap") companies.

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 Boston Trust Midcap 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.

Shareholder Fees (fees paid directly from your investment)
Maximum Sales Charge (load) Imposed on Purchases	None
Maximum Deferred Sales Charge (load)	None
Redemption Fee (as a percentage of amount redeemed, if applicable)	None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fee	0.75%
Distribution and/or Service (12b-1) Fees	None
Other Expenses	0.23%
Total Annual Fund Operating Expenses	0.98%

Example: The 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 a $10,000 investment, a 5% annual return, redemption at the end of each period, and that the Fund's operating expenses remain the same. The Example reflects the fee waiver and expense reimbursement for the duration of the waiver/ reimbursement period only. 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
	$	100			$	312			$	542			$	1,201

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, affect the Fund's performance. For the fiscal year ended December 31, 2025, the Fund's portfolio turnover rate was 29.70% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests, under normal circumstances, at least 80% of its assets in a diversified portfolio of domestic equity securities of mid cap companies. Equity securities include common stock and any rights to purchase common stock. "Assets" means net assets, plus the amount of borrowings for investment purposes. Shareholders will be given 60 days' advance notice of any change to this policy. For these purposes, the Boston Trust Walden Inc. (the "Adviser") defines mid cap companies as those with market capitalizations within the range encompassed by the Russell Midcap^® Index at the time of purchase. The size of companies in the Russell Midcap^® Index may change with market conditions. In addition, changes to the composition of the Russell Midcap^® Index can change the market capitalization range of the companies included in the index. As of December 31, 2025, the market capitalization range of the Russell Midcap^® Index was between $1.1 billion and $101 billion. However, the Fund generally excludes securities with market capitalization less than $2 billion at time of purchase.

ESG Integration: As part of the investment decision-making process for the Fund, the Adviser evaluates how financially material environmental, social, and governance (ESG) risks and opportunities may affect a company's revenues, expenses, assets, liabilities, and overall risk. The consideration of ESG risks and opportunities in investment decision-making is referred to as "ESG integration." The Adviser considers "financial materiality" as it is understood in Generally Accepted Accounting Principles - information that would influence the judgment of an informed investor. The integration of ESG risks and opportunities is often a subjective exercise and may differ depending upon the characteristics of the asset class. The Adviser focuses active ownership efforts in three areas: climate risk, equality, and governance, seeking to ensure companies held across investment strategies are appropriately managing material and significant risks and opportunities. Active ownership activities include proxy voting, company engagement, shareholder resolutions, and public policy advocacy. The Fund is not subject to ESG Screening.

Principal Investment Risks

All investments carry a certain amount of risk and the Fund cannot guarantee that it will achieve its investment objective. The value of the Fund's investments will fluctuate with market conditions and interest rates and the value of your investment in the Fund will also vary. You could lose money on your investment in the Fund, or the Fund could underperform other investments. Investments in the Fund are not deposits of the Adviser or Boston Trust Walden National Association and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Below are the main risks of investing in the Fund.

Market Risk: Market risk refers to the risk related to investments in securities in general and the daily fluctuations in the securities markets.

Equity Risk: The value of the equity securities held by the Fund, and thus the value of the Fund's shares, can fluctuate - at times dramatically.

Mid Cap Company Risk: These companies may be subject to greater market risks and fluctuations in value than large capitalization companies and may not correspond to changes in the stock market in general.

Management Risk: The Adviser's judgments about the attractiveness, value, and potential appreciation of a particular asset class or individual security in which the Fund invests may prove to be incorrect and there is no guarantee that the Adviser's judgment will produce the desired results.

ESG Integration Risk: The Adviser's integration of ESG risks and opportunities may cause the Fund to perform differently from a fund that uses a different methodology. ESG integration may cause the Fund to forego or differently evaluate investment opportunities than a fund that uses a different investment research methodology.

Active Ownership Risk: The Adviser votes proxies in a manner it believes is consistent with the Fund's long-term investment focus. Such votes may not always be consistent with maximizing short-term performance of the issuer.

Issuer Cybersecurity Risk: Issuers of securities in which the Fund invests, counterparties with which the Fund engages in transactions, exchange and other financial market operators, banks, brokers, dealers, and other financial institutions may experience cybersecurity breaches. These breaches may result in harmful disruptions to their operations and may negatively impact the financial condition of the issuer, counterparty, or other market participant.

Potential Conflicts of Interest - 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 Fund and its related companies may pay the intermediary an ongoing fee for providing administrative and related shareholder services.

Ask your salesperson or visit your financial intermediary's website for more information.
