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.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years
Boston Trust Midcap Fund | Boston Trust Midcap Fund | USD ($)	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, 2018, the Fund’s portfolio turnover rate was 19.34% 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 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, 2018, the market capitalization range of the Russell Midcap® Index was between $242 million and $37.5 billion. However, the Fund generally excludes securities with market capitalization less than $2 billion at time of purchase.

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 & Investment Management Company 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.

After-tax returns are calculated using the highest historical individual federal marginal income tax rate and do not reflect the impact of state and local taxes. Actual after-tax returns depend on a shareholder’s tax situation and may differ from those shown. The after-tax returns are not relevant if you hold your Fund shares in tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRA”).
