Asset Management Fund Objective

The Fund seeks long-term capital growth and income through an actively managed portfolio of stocks, bonds and money market instruments.

Equity Fund Objective

The Fund seeks long-term growth of capital through an actively managed portfolio of stocks.

Investment Concerns

Equity securities (stocks) are more volatile and carry more risk and return potential than other forms of investments, including investments in high-grade fixed income securities.

Foreign investing involves risks not typically associated with U.S. investments, including adverse political, social and economic developments and differing auditing and legal standards. These risks are magnified in emerging markets.

Small- to mid-capitalization companies typically have a higher risk of failure and historically have experienced a greater degree of volatility.

Bonds offer a relatively stable level of income, although bond prices will fluctuate, providing the potential for principal gain or loss. Intermediate-term, higher quality bonds generally offer less risk than longer-term bonds and a lower rate of return.

Cash equivalents offer low risk and low return potential.

Manager Commentary (Unaudited)

Management Discussion of Fund Performance

Stocks, as measured by the S&P 500 Index, rose by 18.40% in 2020, a remarkable outcome in its own right but more striking when considering the Index declined by one third during the first quarter of the year. Bond indices also advanced, with the Bloomberg Barclays U.S. Government/Credit Bond Index posting a total return of 8.93%. The rise in value of the Boston Trust Asset Management Fund and the Boston Trust Equity Fund was more muted compared to the rapid rise in many stock indices. For the 12-month period ended December 31, 2020, the Boston Trust Asset Management Fund posted a total return of 7.83%, while the Boston Trust Equity Fund had a total return of 14.53%.

Despite the prevailing turmoil associated with the Coronavirus (COVID-19) pandemic, we remained confident that the crisis would pass eventually. Yet the unknowable depth and duration of the pandemic, and the extent of the associated damage to overall business conditions, led us to assume a more conservative investment position in the Boston Trust Asset Management Fund. For the first time in nearly a decade, we decided to reduce the Fund’s equity allocation closer to the middle, rather than retain equities near the upper end of its specified policy range. We concluded that an equity allocation closer to 60% more prudently reflected the combination of clear near-term economic risks with our core confidence in a return to more normal conditions in time.

As time went on, economic reports suggested that the aggressive fiscal and monetary policy initiatives taken by the federal government had succeeded in removing the worst-case economic scenarios feared broadly in March, 2020. With the full benefit of hindsight, it became clear as well that the pandemic had aided rather than hurt operating conditions of many businesses, in particular those in the distribution and technology sectors that facilitated logistics and communication in our suddenly less mobile society. The cohort of stocks that led the market recovery included several of the giant technology-related companies but also a myriad of newer, less proven companies with, in some cases, astounding expectations for future growth. The Funds had sufficient exposure in the better-situated companies to participate in the market recovery. However, we remained disciplined in our approach and determined it was prudent to avoid what we judged to be more speculative securities, despite the fact that they were enjoying significant stock price momentum. Performance was aided by our decision to increase the Boston Trust Asset Management Fund’s equity allocation gradually through the summer and fall months closer to 70% of total asset value as our confidence in the resilience of the economy improved.*

Looking back, the Funds’ performance for 2020 may have been several percentage points higher had we taken more risk through the year—first by ignoring the pandemic related uncertainty in March, and later by including newer, less proven companies in the portfolio even though their stock valuations were at extreme levels. However, in each Fund’s long life, 2020 was not the first year when our lower risk approach was not rewarded. Nor is it likely to be the last. Yet we remain confident that the balanced, more prudent investment process we have followed since the Funds’ inception will continue to serve shareholders well over the longer term.

As we begin a new year, none of us know if another exogenous event may develop in 2021, or the actual business and political paths that lie ahead. With most stock indices at or near record highs, however, it is reasonable to assume that investors generally expect broad-based economic improvement through the year, with the adverse impact of the pandemic effectively behind us by next summer or fall. Strong gains in overall corporate profits, with continued low inflation and near-zero interest rates, also appear to be embedded in current aggregate stock values. Stocks generally are not undervalued at this time by virtually any traditional metric, but history suggests that overall equity values are likely to continue to trend higher in an environment of rising employment, corporate profits, and overall gross domestic product¹, which we expect through the year. Despite our general optimism about trends in overall equity values, we prefer to continue to avoid the stocks of companies with extreme valuations and overly optimistic estimates of future business performance. In our experience, most of these newer companies will fail to achieve the business success embedded in current stock prices, disappointing their shareholders. Within the equity segment, we have focused instead on companies with a long history of profitability and business models that are tested against the usual competitive forces that surface eventually in every industry.*

Hypothetical Growth of a $100,000 Investment

The above charts represent a 10-year hypothetical $100,000 investment in the Boston Trust Asset Management Fund and the Boston Trust Equity Fund, and includes the reinvestment of dividends and capital gains in the Funds. The returns shown on the table and the graphs do not reflect the deduction of taxes a shareholder would pay on Fund distributions or the redemption of Fund shares.

The Boston Trust Asset Management Fund is measured against a combination of equity and fixed income indices. The Boston Trust Equity Fund is measured against the Standard & Poor’s 500 Index (“S&P 500”), which is widely regarded as a gauge of the U.S. equities market, includes 500 leading companies in leading industries of the U.S. economy. Although the S&P 500 focuses on the large-cap segment of the market, with approximately 75% coverage of U.S. equities, it is also widely viewed as a proxy for the total market. The Bloomberg Barclays U.S. Government/Credit Index includes Treasuries (i.e., public obligations of the U.S. Treasury that have remaining maturities of more than one year), government-related issues (e.g., agency, sovereign, supranational, and local authority debt), and USD Corporates. The Bloomberg Barclays U.S. Government/Credit Bond Index is a component of the Bloomberg Barclays U.S. Aggregate Bond Index. The FTSE 3 Month US T-Bill Index reflects monthly return equivalents of yield averages that are not marked to the market. The index is an average of the last three-month treasury bill issues. The three-month treasury bills are the short-term debt obligations of the U.S. Government. The indexes are unmanaged and their performance does not reflect the deduction of expenses associated with a mutual fund, such as investment management and fund accounting fees. The Funds’ performance reflects the deduction of fees for these services. Investors cannot invest directly in an index.

Fund Objective

The Fund seeks long-term capital growth through an actively managed portfolio of stocks of middle capitalization (“mid cap”) companies.

Investment Concerns

Equity securities (stocks) are more volatile and carry more risk and return potential than other forms of investments, including investments in high-grade fixed income securities.

Mid cap funds typically carry additional risks since smaller companies generally have a higher risk of failure.

Manager Commentary (Unaudited)

Management Discussion of Fund Performance

The fourth quarter performance capped off a strong year for the Russell Midcap^® Index (“Index”), which finished the year 17% higher than where it started in 2020, even with the 27.07% decline in the first quarter. Indeed, from the market trough in late March, the Index advanced nearly 90%. Even though the Boston Trust Midcap Fund outperformed the Index return (-24.25% versus -27.07%) during the first quarter decline, the Fund’s total return of 8.81% for the 12-month period ended December 31, 2020 trailed the Index by a wide margin.

It should perhaps not be surprising that the Fund failed to keep up in the strong market rally of the second, third, and fourth quarters of 2020. In contrast to the fourth quarter where our emphasis on quality and value detracted from results, the Fund’s full year underperformance stemmed primarily from maintaining our valuation discipline. That said, despite the in-line performance of high-quality stocks in general, it is worth highlighting the relative outperformance of loss making entities over profitable peers, which was stunning: loss-makers¹ outperformed profitable companies by more than 60%. Loss-making entities also now comprise 10% of Index value. Given the Fund is entirely invested in stocks of profitable companies, avoiding the loss-making cohort explains much of the relative underperformance.

Outlook

Entering 2021, we can point to several reasons for the optimism that propelled the Index to new all-time highs in the fourth quarter. Among them included: the success in clinical trials and initial distribution of several Coronavirus (COVID-19) vaccines; continued economic recovery supported by significant monetary and fiscal stimuli; somewhat less political uncertainty following the presidential election; and historically low interest rates. However, we also continue to see risk in the current environment: a surge of COVID-19 case counts that is leading to new restrictions on economic activity; a fragile economic recovery still dependent on monetary and fiscal support; and continuing evidence of speculative activity among investors. We believe valuation risk in the market overall to be elevated.

While we do not seek to gain an edge through market timing, we continue to believe that over the long term stock prices ultimately reflect company fundamentals. We do not believe investors will perpetually favor as a group companies that cannot consistently generate profits or free cash flow and yet trade at elevated valuation multiples of sales. Of course, some of these individual companies will emerge as high-quality industry leaders. However, not all, or even a majority of them will succeed. As such, we continue to emphasize in our research and portfolio management activities those companies that have a demonstrated history of profitability, stability, and growth, have sustainable business models, high quality of earnings, and that are trading at reasonable valuations. As of December 31, 2020, the Fund exhibited strong financial characteristics and a more reasonable valuation profile than the Index. As a result, we continue to believe the Fund may provide favorable risk-adjusted returns over the long term.*

Fund Objective

The Fund seeks long-term capital growth through an actively managed portfolio of stocks of small to middle capitalization (“smid cap”) companies.

Investment Concerns

Equity securities (stocks) are more volatile and carry more risk and return potential than other forms of investments, including investments in high-grade fixed income securities.

Smid cap companies typically have a higher risk of failure and historically have experienced a greater degree of volatility.

Manager Commentary (Unaudited)

Management Discussion of Fund Performance

The fourth quarter performance capped off a year of superlatives for the Russell 2500™ Index (“Index”), which finished the year 20% higher than where it started in 2020, despite the 29.72% decline in the first quarter. Indeed, from the market trough in late March, the Index doubled in value. Even with the outperformance of the Fund during the first quarter drawdown (-25.42% versus -29.72%), the Fund’s total return of 8.26% for the 12-month period ended December 31, 2020 underperformed the Index by a wide margin.

It should perhaps not be surprising that the Fund failed to keep up in the strong market rally of the second, third, and fourth quarters of 2020. But to reiterate a theme consistent throughout the year, the underperformance was largely due to style: stocks of higher quality companies, particularly the more reasonably valued cohort, underperformed the overall index by a wide margin, and the Fund performed similarly. The performance gap between stocks of profitable and unprofitable companies was stunning: loss-makers¹outperformed by more than 65%. Loss-making entities also now comprise 18% of the index’s value. Given the Fund is entirely invested in stocks of profitable companies, the “allocation” effect of avoiding the loss-making cohort presented headwinds too strong to overcome, even with execution of our approach that was consistent with expectations.

Outlook

Entering 2021, we can point to several reasons for the optimism that has propelled the Index to new all-time highs in the fourth quarter. Among them included: the success in clinical trials and initial distribution of several Coronavirus (COVID-19) vaccines; continued economic recovery; somewhat less political uncertainty following the U.S. presidential election; and historically low interest rates. However, we also continue to see some risks in the current environment: a new surge of COVID-19 case counts that is leading to new restrictions on economic activity; a fragile economic recovery still dependent on monetary and fiscal support; and continuing evidence of speculative activity among investors.

Boston Trust Walden Balanced Fund

(formerly known as the Walden Balanced Fund)

Boston Trust Walden Equity Fund

(formerly known as the Walden Equity Fund)

December 31, 2020

William H. Apfel, CFA

Portfolio Manager

Boston Trust Walden Inc.

Balanced Fund Objective

The Fund seeks long-term capital growth and income through an actively managed portfolio of stocks, bonds and money market instruments.

Equity Fund Objective

The Fund seeks long-term growth of capital through an actively managed portfolio of stocks.

Investment Concerns

Equity securities (stocks) are more volatile and carry more risk and return potential than other forms of investments, including investments in high-grade fixed income securities. The net asset value per share of these Funds will fluctuate as the value of the securities in the portfolio changes.

Small- to mid-capitalization companies typically have a higher risk of failure and historically have experienced a greater degree of volatility.

Bonds offer a relatively stable level of income, although bond prices will fluctuate, providing the potential for principal gain or loss. Intermediate term, higher quality bonds generally offer less risk than longer-term bonds and a lower rate of return.

Cash equivalents offer low risk and low return potential.

Manager Commentary (Unaudited)

Management Discussion of Fund Performance

The Boston Trust Walden Balanced Fund and the Boston Trust Walden Equity Fund returned 8.26% and 13.28%, respectively for the 12-month period ended December 31, 2020. The relevant market indices, the S&P 500 Index and the Bloomberg Barclays Government/Credit Bond Index, returned 18.40% and 8.93%, respectively, for the year. Both Funds’ equity segments underperformed the S&P 500 Index benchmark, and the Balanced Fund’s fixed income segment underperformed the bond benchmark as well. The Balanced Fund’s relative returns were further negatively impacted by asset allocation. To begin the year, the Balanced Fund’s equity allocation was at the upper end of its range, a stance that had positively aided the Balanced Fund’s returns for much of the last decade. However, as the pandemic caused stocks to sell off sharply in February and March, this significantly detracted from the Balanced Fund’s performance. Though asset allocation decisions in the latter parts of the year were additive, asset allocation on balance was a detractor relative to a static blended benchmark.

That the S&P 500 Index rose more than 18% in 2020 is a remarkable outcome in its own right, but it is more striking when considering the Index declined by one third during the year’s first quarter. Investor confidence oscillated throughout the year, highlighting the tension between economic uncertainty, above average valuations, fiscal and monetary policy intervention, and already low interest rates. The Funds’ relative equity performance tended to follow the shifts in investors’ attitude toward risk, albeit with a more muted degree of protection compared to previous downturns given the unique nature of the pandemic.

According to our analysis of full year returns, the stocks of businesses that had, on average, track records of good fundamental performance regardless of economic conditions fared moderately better on average than their lower quality counterparts. Furthermore, for much of the year the market was especially focused on companies perceived to be capable of delivering improving growth rates, regardless of the challenges presented by the pandemic.

In contrast, our valuation discipline proved to be a substantial headwind for much of 2020, a challenge that was most pronounced in the earlier stages of the recovery from the March market lows. Through much of the spring, investor sentiment seemed to entail a near total suspension of the normal concern regarding extreme valuations. As 2020 neared its end, there was some evidence that valuation was again getting its due consideration. Whether that was exclusively related to optimism about more cyclical parts of the economy or a renewed sensitivity to risk management remains to be seen.

At the sector level, positions in technology and consumer discretionary detracted most from relative results, with a pronounced headwind due to our valuation discipline. Meanwhile, industrial sector holdings contributed positively, as did the absence of investments in the real estate sector.

Outlook

After gaining 55% in value over the last two years, stocks are no longer cheap. But current prices, in our view, still allow for further appreciation. With continued support from the Fed and Congress, and a vast pool of pent up consumer demand, prospects for the economy appear bright. We anticipate that corporate profits will rise substantially in 2021. This includes continued momentum for those companies who either benefited from or were unaffected by the stay-at-home policies, and a rebound for the more economically sensitive companies that saw sharp declines in earnings in 2020. Accordingly, we favor stocks. We remain steadfast in identifying financially strong companies with sustainable business models and reasonable valuations. These stocks should participate in the above tailwinds, but also provide a measure of protection relative to those with riskier businesses and/or shares that imply an unsustainable level of future growth.

Alternatives to stocks have limited appeal. Courtesy of the Fed’s actions, yields on cash and money market funds are effectively zero. Longer dated bonds aren’t much better with the 10-year US Treasury yielding roughly 1%. (Indeed, so-called “real” bond yields – the amount earned after subtracting anticipated inflation – are negative!) But even at these levels, bonds still have a place in the Balanced Fund. Even under the most optimistic forecasts, the path toward full economic recovery is unlikely to be smooth. Stock prices will be volatile, subject to changes in sentiment as well as economic conditions. In contrast, high quality bonds should provide some ballast to the Balanced Fund’s portfolio if equity market conditions worsen. As such, we continue to retain an allocation to bonds.*

Hypothetical Growth of a $100,000 Investment

The above charts represent a 10-year hypothetical $100,000 investment in the Boston Trust Walden Balanced Fund and Boston Trust Walden Equity Fund, and includes the reinvestment of dividends and capital gains in the Funds. The returns shown on the table and the graphs do not reflect the deduction of taxes a shareholder would pay on Fund distributions or the redemption of Fund shares.

The Boston Trust Walden Balanced Fund is measured against a combination of equity and fixed income indices. The Boston Trust Walden Equity Fund is measured against the Standard & Poor’s 500 Index (“S&P 500”), which is widely regarded as a gauge of the U.S. equities market. This index includes 500 leading companies in leading industries of the U.S. economy. Although the S&P 500 focuses on the large-cap segment of the market, with approximately 75% coverage of U.S. equities, it is also widely viewed as a proxy for the total market. The Bloomberg Barclays U.S. Government/Credit Bond Index includes Treasuries (i.e., public obligations of the U.S. Treasury that have remaining maturities of more than one year), government-related issues (i.e., agency, sovereign, supranational, and local authority debt), and USD Corporates. The Bloomberg Barclays U.S. Government/Credit Bond Index is a component of the Bloomberg Barclays U.S. Aggregate Bond Index. The FTSE 3 Month US T-Bill Index reflects monthly return equivalents of yield averages that are not marked to the market. The index is an average of the last three-month treasury bill issues. The three-month treasury bills are the short-term debt obligations of the U.S. Government. The indexes are unmanaged and their performance does not reflect the deduction of expenses associated with a mutual fund, such as investment management and fund accounting fees. The Funds’ performance reflects the deduction of fees for these services. Investors cannot invest directly in an index.

Stephen J. Amyouny, CFA

Lead Portfolio Manager

Richard Q. Williams, CFA

Portfolio Manager

Mark Zagata, CFA

Portfolio Manager

Boston Trust Walden Inc.

Fund Objective

The Fund seeks long-term capital growth through an actively managed portfolio of stocks of middle capitalization (“mid cap”) companies.

Investment Concerns

Equity securities (stocks) are more volatile and carry more risk and return potential than other forms of investments, including investments in high-grade fixed income securities.

Mid cap funds typically carry additional risks since smaller companies generally have a higher risk of failure.

Manager Commentary (Unaudited)

Management Discussion of Fund Performance

The fourth quarter performance capped off a strong year for the Russell Midcap^® Index (“Index”), which finished the year 17% higher than where it started in 2020, even with the 27.07% decline in the first quarter. Indeed, from the market trough in late March, the Index advanced nearly 90%. Even though the Boston Trust Walden Midcap Fund outperformed the Index return (-24.05% versus -27.07%) during the first quarter decline, the Fund’s total return of 8.76% for the 12-month period ended December 31, 2020 trailed the Index by a wide margin.

Outlook

Entering 2021, we can point to several reasons for the optimism that propelled Index to new all-time highs in the fourth quarter. Among them included: the success in clinical trials and initial distribution of several Coronavirus (COVID-19) vaccines; continued economic recovery supported by significant monetary and fiscal stimuli; somewhat less political uncertainty following the presidential election; and historically low interest rates. However, we also continue to see risk in the current environment: a surge of COVID-19 case counts that is leading to new restrictions on economic activity; a fragile economic recovery still dependent on monetary and fiscal support; and continuing evidence of speculative activity among investors. We believe valuation risk in the market overall to be elevated.

Manager Commentary (Unaudited)

Management Discussion of Fund Performance

The fourth quarter performance capped off a year of superlatives for the Russell 2500™ Index (“Index”), which finished the year 20% higher than where it started in 2020, despite the 29.72% decline in the first quarter. Indeed, from the market trough in late March, the Index doubled in value. Even with the outperformance of the Fund during the first quarter drawdown (-25.03% versus -29.72%), the Fund’s total return of 9.13% for the 12-month period ended December 31, 2020 underperformed the Index by a wide margin.

Fund Objective

The Fund seeks long-term capital growth through an actively managed portfolio of stocks of small capitalization (“small cap”) companies.

Investment Concerns

Equity securities (stocks) are more volatile and carry more risk and return potential than other forms of investments, including investments in high-grade fixed income securities.

Small cap funds typically carry additional risks since smaller companies generally have a higher risk of failure, and historically, their stocks have experienced a greater degree of market volatility than stocks on average.

Manager Commentary (Unaudited)

Management Discussion of Fund Performance

The fourth quarter performance capped off a year of superlatives for the Russell 2000^®Index (“Index”), which finished the year 20% higher than where it started in 2020, despite the 30.61% decline in the first quarter. Indeed, from the market trough in late March, the Index doubled in value. Even with the outperformance of the Fund during the first quarter drawdown (-26.16% versus -30.61%), the Fund’s total return of 8.17% for the 12-month period ended December 31, 2020 underperformed the Index by a wide margin.

It should perhaps not be surprising that the Fund failed to keep up in the strong market rally of the second, third, and fourth quarters. But to reiterate a theme consistent throughout the year, the underperformance was largely due to style: stocks of higher quality companies, particularly the more reasonably valued cohort, underperformed the overall index by a wide margin, and the Fund performed similarly. The performance divide between stocks of profitable and unprofitable companies was stunning: loss-makers¹ outperformed by more than 50%. Loss-making entities now comprise 23% of the Index’s value. Given the Fund is entirely invested in stocks of profitable companies, the “allocation” effect of avoiding the loss-making cohort presented headwinds too strong to overcome, even with execution of our approach that was consistent with expectations.

Outlook

Entering 2021, we can point to several reasons for the optimism that have propelled the Index to new all-time highs in the fourth quarter. Among them included: the success in clinical trials and initial distribution of several Coronavirus (COVID-19) vaccines; continued economic recovery; somewhat less political uncertainty following the presidential election; and historically low interest rates. However, we also continue to see risk in the current environment: a new surge of COVID-19 case counts that is leading to new restrictions on economic activity; a fragile economic recovery still dependent on monetary and fiscal support; and continuing evidence of speculative activity among investors. We believe valuation risk in the market overall to be elevated.

While we do not seek to gain an edge through market timing, we continue to believe that over the long term stock prices ultimately reflect company fundamentals. We do not believe investors will perpetually favor, as a group, companies that cannot consistently generate profits or free cash flow and yet trade at elevated valuation multiples of sales. Of course, some of these individual companies will emerge as high-quality industry leaders. However, not all, or even a majority of them will succeed. As such, we continue to emphasize in our research and portfolio management activities those companies that have a demonstrated history of profitability, stability, and growth, have sustainable business models, high quality of earnings, and that are trading at reasonable valuations. As of December 31, 2020, the Fund exhibits strong financial characteristics and a more reasonable valuation profile than the Index. As a result, we continue to believe the strategy may provide favorable risk-adjusted returns over the long term.^*

Portfolio Manager

Boston Trust Walden Inc.

Fund Objective

The Fund seeks long-term capital growth through an actively managed portfolio of equities of international companies.

Investment Concerns

Foreign investing involves risks not typically associated with U.S. investments, including adverse political, regulatory, social and economic developments and differing auditing and legal standards. These risks are magnified in emerging markets.

Equity securities (stocks) are more volatile and carry more risk and return potential than other forms of investments, including investments in high-grade fixed income securities.

Mid-capitalization funds typically carry additional risks since smaller companies generally have a higher risk of failure.

Manager Commentary (Unaudited)

Management Discussion of Fund Performance

For the 12-month period ended December 31, 2020, the Boston Trust Walden International Equity Fund posted a total return of 7.16%. The Fund’s return trailed that of its primary benchmark, the MSCI World ex-USA Index (net) (“Index”), which posted a return of 7.59% for the year.

Global equity markets declined sharply in the first quarter of 2020 as economies slowed when the Coronavirus (COVID-19) pandemic took hold and government policies, along with fear of contagion, compelled people to stay home as much as possible. This led to lower spending on the part of consumers and businesses, and corporate earnings estimates for the year declined. Deterioration in fundamentals and rising volatility in financial markets led many investors to sell stocks; at its trough on March 23, 2020, the Index was down 34.21% year-to-date.

Governments around the globe answered with fiscal and monetary policy moves that quickly reversed the rout in financial markets. As the pandemic waned in the summer, economic activity in many parts of the world increased to near-normal levels, and stocks rose commensurately. In the fall, COVID-19 cases increased in many developed markets, but promising vaccine results and their initial rollout, along with continued government support of economies around the globe, propelled the equity market ever-higher through the remainder of the year.

Certain market segments fared better than others did. Most geographies performed well; of the 22 countries represented in the Index, all but six achieved a positive return for 2020. Of the decliners, most were smaller and less diversified equity markets; the only one of significant size was the UK, which grappled with the effects of an impending Brexit and a worse pandemic than many other countries. Most sectors also posted positive returns for the year, though there was a notable gap between the best performers and the worst. Certain sectors, like Information Technology, benefited from the stay-at-home lifestyle, while others, like Energy, suffered from lower use of their products worldwide.

Turning to other market factors, quality was a slight tailwind for the year. Stocks that appear to be high quality, as measured by the Adviser’s proprietary quality metric, outperformed lower quality stocks for the year. All the outperformance came in the first quarter as more stable companies with lower levels of debt were rewarded during the economic and market downturn; during the following nine months of the year higher quality stocks underperformed slightly. The Fund was overweight higher quality stocks relative to its benchmark throughout 2020, so this provided a modest performance benefit.

Expensive stocks, as measured by the Adviser’s proprietary valuation metric, outperformed the broader market for the year. This negatively affected the Fund’s performance, as it was underweight that segment of the market. This was offset, however, by an underweight position in the cheapest stocks relative to its benchmark, which underperformed the market during the year.*

Notes to the Financial Statements

December 31, 2020

Organization:

The Boston Trust Walden Funds (the “Trust”) was organized on January 8, 1992 as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust contains the following funds (individually a “Fund”, collectively the “Funds”), each of which are registered as a diversified Fund under the 1940 Act:

Fund	Short Name
Boston Trust Asset Management Fund	Asset Management Fund
Boston Trust Equity Fund	Equity Fund
Boston Trust Midcap Fund	Midcap Fund
Boston Trust SMID Cap Fund	SMID Cap Fund
Boston Trust Walden Balanced Fund (formerly Walden Balanced Fund)*	BTW Balanced Fund
Boston Trust Walden Equity Fund (formerly Walden Equity Fund)*	BTW Equity Fund
Boston Trust Walden Midcap Fund (formerly Walden Midcap Fund)*	BTW Midcap Fund
Boston Trust Walden SMID Cap Fund (formerly Walden SMID Cap Fund)*	BTW SMID Cap Fund
Boston Trust Walden Small Cap Fund	BTW Small Cap Fund
Boston Trust Walden International Equity Fund (formerly Walden International Equity Fund)*	BTW International Equity Fund

* The Fund changed its name effective September 30, 2020.

The investment objective of the Asset Management Fund and BTW Balanced Fund is to seek long-term capital growth and income through an actively managed portfolio of stocks, bonds and money market instruments. The investment objective of the Equity Fund and BTW Equity Fund is to seek long-term capital growth through an actively managed portfolio of stocks. The investment objective of the Midcap Fund and BTW Midcap Fund is to seek long-term capital growth through an actively managed portfolio of stocks of middle capitalization companies. The investment objective of the SMID Cap Fund and BTW SMID Cap Fund is to seek long-term capital growth through an actively managed portfolio of stocks of small to middle capitalization companies. The investment objective of the BTW Small Cap Fund is to seek long-term capital growth through an actively managed portfolio of stocks of small capitalization companies. The investment objective of the BTW International Equity Fund is to seek long-term capital growth through an actively managed portfolio of equities of international companies.

Under the Trust’s organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust. In addition, in the normal course of business, the Trust may enter into contracts with its vendors and others that provide for general indemnifications. Each Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Funds. However, based on experience, the Funds expect risk of loss to be remote.

Significant Accounting Policies:

The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements. The policies are in conformity with accounting principles generally accepted in the United States of America (“GAAP”).

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results may differ from those estimates.

The Funds are investment companies and accordingly follow the investment company accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, “Financial Services - Investment Companies”.

Security Valuation:

The Funds record their investments at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The valuation techniques used to determine fair value are further described below.

The value of each equity security, including common stocks, is based either on the last sale price on a national securities exchange, or in the absence of recorded sales, at the closing bid price on such exchanges, or at the quoted bid price in the over-the-counter market. Equity securities traded on the NASDAQ stock market are valued at the NASDAQ official closing price. The prices for foreign securities are reported in local currency and converted to U.S dollars using currency exchange rates. Prices for most securities held in the Funds are provided daily by a recognized independent pricing service.

Bonds and other fixed income securities (other than short-term obligations but including listed issues) are provided by an independent pricing service, the use of which has been approved by the Board of Trustees (“Board”). In making such valuations, the pricing service utilizes both dealer-supplied valuations and electronic data processing techniques that take into account appropriate factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, and trading characteristics other than market data and without exclusive reliance upon quoted prices or exchanges or over-the-counter prices, since such valuations are believed to reflect more accurately the fair value of such securities. All debt portfolio securities with a remaining maturity of 60 days or less may be valued at amortized cost, which approximates fair value.

The Trust may use a pricing service to value certain portfolio securities where the prices provided are believed to reflect the fair value of such securities. If market prices are not readily available or, in the opinion of the Adviser, market prices do not reflect fair value, or if an event occurs after the close of trading on the exchange or market on which the security is principally traded (but prior to the time the NAV is calculated) that materially affects fair value, the Adviser will value the Funds’ assets at their fair value according to policies approved by the Board. The Adviser believes that foreign security values may be affected by volatility that occurs in global markets on a trading day after the close of any given foreign securities

Notes to the Financial Statements

December 31, 2020

markets. The fair valuation procedures, therefore, include a procedure whereby foreign security prices may be “fair valued” by an independent pricing service through the use of factors which take such volatility into account.

Investments in investment companies and money market funds are valued at NAV per share.

Fair Value Measurements:

The valuation techniques employed by the Funds, as described above in Security Valuation, maximize the use of observable inputs and minimize the use of unobservable inputs in determining fair value. The inputs used for valuing the Funds’ investments are summarized in the three broad levels listed below:

Level 1 — Quoted prices in active markets for identical assets

Level 2 — Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

Level 3 — Significant unobservable inputs (including the Funds’ own assumptions in determining the fair value of investments)

The inputs or methodology used to value investments are not necessarily an indication of the risk associated with investing in those investments.

Pursuant to the valuation techniques described above in Security Valuation, equity securities are generally categorized as Level 1 securities in the fair value hierarchy (unless there is a fair valuation event, in which case affected securities are generally categorized as Level 2 securities). Fixed income securities, including those with a remaining maturity of 60 days or less, are generally categorized as Level 2 securities in the fair value hierarchy.

Open-ended investment companies and money market funds are generally categorized as Level 1 securities in the fair value hierarchy.

Investments for which there are no quotations available, or for which quotations do not appear reliable, are valued at fair value as determined in good faith by the Adviser under the direction of the Board. These valuations are typically categorized as Level 2 or Level 3 in the fair value hierarchy.

The Funds did not hold any Level 3 investments during the year ended December 31, 2020

The following is a summary of the valuation inputs used as of December 31, 2020 in valuing the Funds’ investments based on the three levels defined above:

Investment Transactions and Related Income:

Investment transactions are accounted for no later than one business day after trade date. However, for financial reporting purposes, investment transactions are accounted for on trade date. Investment gains and losses are calculated on an identified cost basis. Interest income is recognized on an accrual basis and includes, where applicable, the amortization or accretion of premium or discount based on effective yield. Dividend income is recorded on the ex-dividend date except in the case of certain foreign securities, in which case dividends are recorded as soon as such information becomes available.

Real Estate Investment Trusts:

The Funds may own shares of real estate investment trusts (“REITs”), which report information on the source of their distribution annually. Certain distributions received from REITs during the year, which are known to be return of capital, are recorded as a reduction to the cost of the individual REIT. These cost adjustments are typically based on estimates since actual return of capital amounts are not known at the time the annual report is prepared.

Expenses:

Expenses directly attributable to a Fund are charged directly to that Fund. Expenses relating to the Trust are allocated proportionately to each Fund within the Trust according to the relative net assets of each Fund or on another reasonable basis.

Distributions to Shareholders:

Distributions to shareholders are recorded on the ex-dividend date. Dividends to shareholders from net investment income, if any, are declared and paid annually by the Funds. Dividends to shareholders from net realized gains, if any, are declared and distributed at least annually by the Funds. The amounts of distributions to shareholders from net investment income and of distributions from net realized gains are determined in accordance with federal income tax regulations, which may differ from GAAP.

Federal Income Taxes:

Each Fund qualifies and intends to continue to qualify as a regulated investment company by complying with the provisions available to certain investment companies, as defined in Subchapter M of the Internal Revenue Code, and to make distributions from net investment income and from net realized capital gains sufficient to relieve it from all, or substantially all, federal income and excise taxes. Therefore, no federal income tax provision is required.

Management has reviewed tax positions taken in tax years that remain subject to examination by all major tax jurisdictions, including U.S. Federal (i.e., the last four tax year ends and the interim tax period since then, as applicable), and believes that there is no tax liability resulting from unrecognized tax benefits related to uncertain tax positions taken as of and during the year ended December 31, 2020. The Funds recognize interest and penalties, if any, related to unrecognized tax benefits, as income tax expense in the Statements of Operations as incurred. There is no income tax noted as due for the year ended December 31, 2020.

Foreign Currency Transactions:

The accounting records of the Funds are maintained in U.S. dollars. Non-U.S. dollar denominated amounts are translated into U.S. dollars as follows, with the resultant exchange gains and losses recorded in the Statements of Operations:

Value of investment securities and other assets and liabilities at the exchange rate on the valuation date; and

ii) Purchases and sales of Investment securities and income and expenses at the exchange rate prevailing on the respective date of such transactions.

Notes to the Financial Statements

December 31, 2020

The Funds do not isolate realized and unrealized gains and losses attributable to changes in the exchange rates from gains and losses that arise from changes in the value of investments. Such fluctuations are included with net realized and unrealized gain or loss from investments.

Investment income from non-U.S. sources received by a Fund is generally subject to non-U.S. withholding taxes at rates ranging up to 30%. Such withholding taxes may be reduced or eliminated under the terms of applicable U.S. income tax treaties. The Funds may be subject to foreign taxes on gains in investments or currency repatriation. The Funds accrue such taxes, as applicable, based on their current interpretation of tax rules in the foreign markets in which they invest.

Related Party Transactions and Other Service Arrangements:

Investment Adviser:

The Trust, with respect to the Funds, and the Adviser are parties to an Investment Advisory Agreement under which the Adviser is entitled to receive an annual fee, computed daily and paid monthly, equal to the average daily net assets of each Fund, at the following annual percentage rates before contractual waivers:

Fund	Fee Rate
Asset Management Fund		0.72	%*
Equity Fund		0.75	%
Midcap Fund		0.75	%
SMID Cap Fund		0.75	%

Fund	Fee Rate
BTW Balanced Fund		0.75	%
BTW Equity Fund		0.75	%
BTW Midcap Fund		0.75	%
BTW SMID Cap Fund		0.75	%
BTW Small Cap Fund		0.75	%
BTW International Equity Fund		0.75	%

Effective rate for year ended December 31, 2020. The Asset Management Fund has an Investment Management Agreement with the Adviser under which the Fund pays: (a) 0.75% of the first $500 million of average daily net assets; (b) 0.50% of average daily net assets in excess of $500 million.

Additionally, two trustees of the Trust are officers of the Adviser or its affiliate, and an officer of the Trust is an officer of the Adviser. These persons are not paid directly by the Funds.

Administration and Fund Accounting:

Citi Fund Services Ohio, Inc. (“Citi”) serves the Funds as administrator. Citi provides administrative and fund accounting services for a fee that is computed daily and paid monthly, based on the aggregate daily net assets of the Trust plus certain base fees.

Certain officers of the Trust are affiliated with Citi. Such persons were paid no fees directly by the Funds for serving as Officers of the Trust. Citi makes an employee available to serve as the Trust’s Chief Compliance Officer (“CCO”) under a Compliance Service Agreement between the Funds and Citi (the “CCO Agreement”). Under the CCO Agreement, Citi also provides infrastructure and support in implementing the written policies and procedures comprising the Trust’s compliance program, including support services to the CCO. For the services provided under the CCO Agreement, the Funds paid Citi $150,000 for the year ended December 31, 2020, plus certain out of pocket expenses. Citi pays the salary and other compensation earned by the CCO as an employee of Citi.

Distribution:

Foreside Financial Services, LLC (“Foreside”), which is not affiliated with Citi or the Adviser, serves as the Funds’ distribution agent. Fees for these services are paid monthly by the Adviser and not by the Funds.

Shareholder Services:

The Funds may enter into shareholder services agreements with investment advisers, banks, trust companies and other types of organizations (“Authorized Service Providers”), which may include affiliates of the Funds, for providing administrative services with respect to shares of the Funds attributable to or held in the name of the Authorized Service Provider for its clients or other parties with whom they have a servicing relationship. Fees paid by the Funds under shareholder services agreements may not exceed 0.25% of the average daily net assets of each Fund and are presented separately on the Statements of Operations. Affiliates of the Funds did not receive any fees during the year ended December 31, 2020.

Custodian and Transfer Agency:

Boston Trust Walden Company (“Boston Trust”), the parent company of the Adviser, acts as the Funds’ transfer agent. Under the transfer agency agreement, Boston Trust receives a fixed fee of $18,000 annually per fund, accrued daily and paid monthly for its services. Under a sub-transfer agency agreement, FIS Investor Services, LLC receives a fixed annual fee accrued daily and paid monthly, plus annual per account fees and certain out of pocket expenses for its services to the Trust. Expenses incurred under the transfer agency agreement and sub-transfer agency agreement are presented collectively as “Transfer Agency” expenses on the Statements of Operations.

Boston Trust acts as the custodian for all Funds except the BTW International Equity Fund. Under the custody agreement, Boston Trust receives an annual asset based fee of 0.014% of the value of securities held. Citibank, N.A. receives sub-custodian fees from Boston Trust for each Fund except the BTW International Equity Fund. Under a separate custody agreement, Citibank, N.A., an affiliate of Citi, serves as custodian for the BTW International Equity Fund and receives a fee based on a percentage of assets held on behalf of the BTW International Equity Fund, transaction fees and certain out of pocket expenses for its services. Such percentages vary by the jurisdiction in which the assets are held.

Fee Reductions:

The Adviser has agreed to reduce its fees payable by the Funds to the extent necessary, exclusive of brokerage costs, interest, taxes, dividends, litigation, indemnification, expenses associated with the investments in underlying investment companies and extraordinary expenses (as determined under GAAP) of each Fund, except the SMID Cap Fund , to 1.00% of the average daily net assets. The Adviser has agreed to reduce its fees payable by the SMID Cap Fund to the extent necessary, subject to certain exclusions, to limit the aggregate annual operating expenses to 0.75% of its average daily net assets. Prior to December 31, 2020, the contractual expense limitation for the BTW International Equity Fund was 1.10%. Any such

Notes to the Financial Statements

December 31, 2020

reductions made by the Adviser in its fees or in the payment or reimbursement of expenses that are a Fund’s obligation may be subject to repayment by the Fund within three years provided the Fund receiving the reduction, payment or reimbursement is able to effect such repayment and remain in compliance with applicable expense limitations. The expense limitation agreement shall automatically renew effective May 1 of every year until the Adviser provides written notice of non-renewal to the Trust.

Pursuant to its agreement, the Adviser reimbursed, and has yet to recoup, fees in the following amounts for the years ended December 31, 2018 (expiring 12/31/2021), December 31, 2019 (expiring 12/31/2022) and December 31, 2020 (expiring 12/31/2023):

SMID Cap Fund	$	4,663,238		244,533	$	4,664

During the year ended December 31, 2019, the Asset Management Fund acquired securities and other assets from a common trust fund managed by an affiliate (Boston Trust Walden Company) of the Adviser, the Boston Trust Managed Growth Fund. The subscription proceeds were accomplished through an in-kind contribution of investments and other assets. The contribution was not a taxable event under the provisions of Section 584 of the Internal Revenue Code, and therefore the historical cost basis of those investments was carried forward. The Asset Management Fund issued 808,358 shares to the holders of Boston Trust Managed Growth Fund in exchange for investments and other assets valued at $43,771,772. The value and historical cost of the contributed investments was $43,613,987and $16,186,943, respectively, which was carried forward to align the ongoing reporting of realized and unrealized gains and losses for tax purposes.

During the year ended December 31, 2019, the Funds delivered securities in exchange for the redemption of shares (redemptions in-kind) as follows:

			Fund Shares		Realized
Fund	Fair Value		Redeemed		Gain/(Loss)

BTW Small Cap Fund		119,901,316		8,413,292		42,132,134

Interfund Lending:

Pursuant to an Exemptive Order issued by the Securities and Exchange Commission (“SEC”), the Funds may participate in an interfund lending program (the “Program”). The Program provides an alternative credit facility under which the Funds may lend to, or borrow from, one another, consistent with each Fund’s investment objectives, limitations and organization documents. The Program provides a borrowing Fund with a source of liquidity at a rate lower than the bank borrowing rate at times when the cash position of the Fund is insufficient to meet temporary cash requirements. In addition, Funds making short-term cash loans directly to other Funds would earn interest at a rate higher than they otherwise could obtain from investing their cash in repurchase agreements or certain other short-term money market instruments. Interfund loans have a maximum duration of seven days and may be called on one business day’s notice. Any open loans at period end are presented under the caption “Payable” for interfund lending in the Statements of

Notes to the Financial Statements

The differences between book-basis and tax-basis unrealized appreciation (depreciation) is attributable primarily to tax deferral of losses on wash sales and return of capital distributions from REIT securities and other investments.

As of the end of its tax year ended December 31, 2020, the following Funds have a net capital loss carry forwards (“CLCFs”) not subject to expiration as summarized in the tables below. The Board does not intend to authorize a distribution of any realized gain for the Fund until any applicable CLCF has been offset or expires.

	Short-Term		Long-Term
Fund	Amount		Amount		Total
SMID Cap Fund	$	–	$	219,383	$	219,383
BTW International Equity Fund		–		829,667		829,667

Notes to the Financial Statements

December 31, 2020

As of December 31, 2020, the following reclassifications have been made on the Statements of Assets and Liabilities to increase (decrease) such accounts with offsetting adjustments as indicated:

	Total Distributable
Fund	Earnings			Paid in Capital
SMID Cap Fund	$	83,041		$	(83,041	)
BTW Midcap Fund		(34,628	)		34,628
BTW SMID Cap Fund		(3,828	)		3,828
BTW Small Cap Fund		(1,271,029	)		1,271,029

These “book/tax” differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature (e.g. return of capital, distribution reclass, foreign currency reclass, and equalization), such amounts are reclassified within the composition of net assets based on their federal tax-basis treatment; temporary differences (e.g. wash sales and post October losses) do not require reclassification. To the extent dividends to shareholders exceed net investment income and net realized gains for tax purposes, they are reported as return of capital.

Control Ownership and Principal Holders:

The beneficial ownership, either directly or indirectly, of more than 25% of the voting securities of a Fund creates presumptions of control of the Fund under section 2 (a)(9) of the 1940 Act. As of December 31, 2020, the Funds had individual shareholder accounts and/or omnibus shareholder accounts (comprised of a group of individual shareholders), owning more than 25% of the total shares outstanding of the Fund as detailed below.

Fund	Control Ownership	Percentage of Ownership
Asset Management Fund	US Bank N.A.	88.82%
Equity Fund	US Bank N.A.	95.33
Midcap Fund	US Bank N.A.	45.82
SMID Fund	National Financial Services	40.97
BTW Balanced Fund	US Bank N.A.	52.58
BTW Equity Fund	US Bank N.A.	29.82

Business Combination:

In December 2019, the Board approved Boston Trust Walden’s proposal to merge Walden Small Cap Fund (the “Target Fund”) into Boston Trust Walden Small Cap Fund (the “Acquiring Fund”). The Agreement and Plan of Reorganization was approved by shareholders on March 26, 2020. The Target Fund and the Acquiring Fund shared identical investment goals, principal investment strategies, risks, and ESG screens. They also shared the same investment adviser. The transaction was effective after the close of business on April 3, 2020. The Acquiring Fund acquired all of the assets and assumed all of the liabilities of the Target Fund as shown in the table below. The transaction was structured to qualify as a tax-free reorganization under the Code. Pursuant to the Agreement and Plan of Reorganization, shareholders of the Target Fund received a number of shares of the corresponding class in the Acquiring Fund, with a value equal to their holdings in the Target Fund as of the close of business on April 3, 2020. The investment portfolio of the Target Fund, with a fair value of $103,000,783 and identified cost of $111,464,003 as of the date of the reorganization, was the principal asset acquired by the Acquiring Fund. For financial statement purposes, assets received and shares issued by the Acquiring Fund were recorded at fair value; however, the cost basis of the investments received from the Target Fund was carried forward to align ongoing reporting of the Acquiring Fund’s realized and unrealized gains and losses with amounts distributable to shareholders for tax purposes.

The following is a summary of Shares Outstanding, Net Assets, NAV and Net Unrealized Appreciation (Depreciation) immediately before and after the reorganization:

							Net Unrealized
	Shares				Net Asset Value		Appreciation
Target Fund	Outstanding		Net Assets		Per Share		(Depreciation)
Walden Small Cap Fund		7,088,420	$	103,030,710	$	14.54	$	(8,463,220	)

Acquiring Fund
Boston Trust Walden Walden Small Cap Fund		19,128,805	$	189,922,749	$	9.93	$	(23,454,940	)

Post Reorganization
Boston Trust Walden Walden Small Cap Fund		29,505,631	$	292,953,459	$	9.93	$	(31,918,160	)

Expenses related to reorganization were incurred by the Adviser. Expenses incurred by the Funds in the ordinary course during the reorganization continue to be treated as a Fund expense in accordance with the Funds’ advisory contracts.

Notes to the Financial Statements

December 31, 2020

Assuming the reorganization had been completed on January 1, 2020, the beginning of the annual reporting period, the pro forma results of operations of the Acquiring Fund, post reorganization for the year ended December 31, 2020, are as follows:

Net Investment income (loss)	$	3,155,490
Net realized/unrealized gains (losses)		72,763,265
Change in net assets resulting from operations	$	75,918,755

Because the combined investment portfolios have been managed as a single integrated portfolio since the reorganization was completed, it is not practicable to separate the amounts of revenue and earnings of the Target Fund that have been included in the Statements of Operations of the Acquiring Fund, post reorganization since April 4, 2020

Subsequent Events:

Management has evaluated events and transactions through the date these financial statements were issued and concluded no subsequent events required recognition or disclosure in these financial statements.

Basis for Opinion

These financial statements are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of December 31, 2020, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements.

Table of Shareholder Expenses:

As a shareholder of the Trust, you incur ongoing costs, including management fees, and other Fund expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in the Boston Trust Walden Funds and to compare these costs with the ongoing costs of investing in other mutual funds.

These examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire period from July 1, 2020 through December 31, 2020.

Actual Expenses

The table below provides information about actual account values and actual expenses. You may use the information below together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the table under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect the costs incurred by the Funds for buying and selling securities. The Funds do not charge transaction fees, such as redemption fees, nor do the Funds charge a sales charge (load). Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

				Annualized
	Beginning	Ending	Expenses Paid	Expense Ratio
	Account Value	Account Value	During Period	During Period
	7/1/20	12/31/20	7/1/20 - 12/31/20*	7/1/20 - 12/31/20
Asset Management Fund	$1,000.00	$1,154.00	$4.66	0.86%
Equity Fund	1,000.00	1,237.50	4.95	0.88
Midcap Fund	1,000.00	1,222.60	5.59	1.00
SMID Cap Fund	1,000.00	1,233.50	4.21	0.75
BTW Balanced Fund	1,000.00	1,145.00	5.39	1.00
BTW Equity Fund	1,000.00	1,230.90	5.61	1.00
BTW Midcap Fund	1,000.00	1,220.70	5.58	1.00
BTW SMID Cap Fund	1,000.00	1,230.60	5.61	1.00
BTW Small Cap Fund	1,000.00	1,274.60	5.72	1.00
BTW International Equity Fund	1,000.00	1,170.50	5.40	0.99

Expenses are equal to the average account value multiplied by the Fund’s annualized expense ratio multiplied by 184/365 (the number of days in the most recent fiscal half-year divided by the number of days in the fiscal year).

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and hypothetical expenses based on each Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect the costs incurred by the Funds for buying and selling securities. The Funds do not charge transaction fees, such as redemption fees, nor do the Funds charge a sales charge (load). Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

Investment Adviser Contract Approval (Unaudited)

December 31, 2020

The annual consideration by the Board of Trustees (the “Board”) of the continuation of the investment advisory agreement between Boston Trust Walden Inc., (the “Adviser”) and Boston Trust Asset Management Fund, Boston Trust Equity Fund, Boston Trust Midcap Fund, Boston Trust SMID Cap Fund, Boston Trust Walden Small Cap Fund, Boston Trust Walden Balanced Fund, Boston Trust Walden Equity Fund, Boston Trust Walden Midcap Fund, Boston Trust Walden SMID Cap Fund, and Boston Trust Walden International Equity Fund (the “Funds”).

Section 15 of the Investment Company Act of 1940 (the “1940 Act”) requires that the Investment Advisory Agreement with Boston Trust Walden Inc. (the “Adviser”) be renewed annually by the Board of Trustees of Boston Trust Walden Funds (the “Trust”), including a majority of the Board who are not “interested persons” of the Trust or of the Adviser. It is the duty of the Board to request as much information as is reasonably necessary to evaluate the terms of the Investment Advisory Agreement and determine whether its continuance is fair to the Funds and their shareholders. The Board considered the continuation of the Investment Advisory Agreement at an in-person meeting held on August 18, 2020. The Board requested, and the Adviser provided, information and data relating to: (i) the investment performance of each series of the Trust (the “Funds”) and the Adviser; (ii) the nature, extent and quality of the services provided by the Adviser to the Funds; (iii) the cost of the services to be provided and the profits to be realized by the Adviser and its affiliates from the relationship with the Funds; (iv) the extent to which economies of scale will be realized as the Funds grow; (v) whether the fee levels reflect these economies of scale to the benefit of Funds’ shareholders; (vi) the advisory fees paid by other comparable funds advised by the Adviser or by a different investment adviser; (vii) the Funds’ expense ratios and the expense ratios of similar funds; and (viii) the effect of any fee waivers and expense reimbursements made by the Adviser.

At the meeting on August 18, 2020, the Board engaged in a thorough review process to determine whether to continue the Investment Advisory Agreement. The Board met directly with representatives of the Adviser and reviewed the information and data listed above, as supplemented by Citi Fund Services Ohio, Inc., the Trust’s administrator. As part of its deliberations, the Board also considered and relied upon the information about the Funds and the Adviser that it had received throughout the year as part of its ongoing oversight of the Funds and their operations.

The Board carefully considered the nature, extent and quality of the services provided by the Adviser. The Board discussed the organizational structure of Adviser and its investment philosophy, portfolio construction process and fixed income approach. The Board discussed the Adviser’s approach to sustainable, responsible and impact investing, including its environmental, social and governance research framework and its portfolio screening guidelines. The Board reviewed the Adviser’s experience and the capabilities of its personnel, as well as the quality of the reports and other materials received from the Adviser. The Board reviewed biographical information about the employees of the Adviser and its parent, Boston Trust Walden Company (“Boston Trust”). The Board addressed the Adviser’s brokerage allocation and execution strategy, noting that the Adviser does not take into consideration sales of Fund shares in selecting brokers through which its affects Fund portfolio transactions. The Board also discussed the Adviser’s compliance program, business continuity and disaster recovery plans, succession planning and employee ownership. Considering the personnel involved in servicing the Funds, as well as the materials and services described above, the Board expressed satisfaction with the quality of the services received from the Adviser.

Next, the Board reviewed the performance of the Funds from inception through June 30, 2020, comparing the performance to various indices and, in the case of the Boston Trust Asset Management Fund and the Walden Balanced Fund, to a bond index, equity index and Treasury bills. The Board noted that as of June 30, 2020, while each Fund outperformed the index and its peer group at various times for the Year-to-Date, 1-year, 3-year, 5-year and Since Inception periods, each Fund generally performed in line with its peer group during the same periods. The Board noted that while the Funds underperformed their benchmarks at various times, performance was consistent with the long-term performance pattern of each Fund’s investment style, as they participated in rising markets and outperformed in falling markets. The Board noted that this downside protection is consistent with the Adviser’s strategy and is routinely communicated to clients and investors. The Board also noted that during a rising market lasting over a decade, the Funds have consistently adhered to a lower risk, higher quality strategy.

The Board noted that the advisory fees for each Fund are within the range of their peer groups. The Board noted that the Adviser has been operating under an Expense Limitation Agreement that requires the Adviser to waive fees and/or reimburse expenses to the extent total operating expenses exceed 0.75% for the Boston Trust SMID Cap Fund, 1.10% for the Walden International Equity Fund and 1.00% for all the other Funds.

Turning to total operating expenses, the Board discussed the components of the Funds’ expense ratios and the services and value shareholders receive in exchange for the fees paid and expense borne by the Funds. The Board noted that the expense ratios for all the Funds were within the range of total operating expenses of the funds in the peer groups. After considering the comparative data as described above, and the Expense Limitation Agreement that was previously renewed by the Board at its February 26, 2020 meeting, the Board concluded that the advisory fees and expense ratios were reasonable.

In reviewing the costs of the services to be provided and the profits to be realized by the Adviser, the Board reviewed the Adviser’s income statement for the 12-months ended December 31, 2019 and the six-months ended June 30, 2020, as well as the gross and net profit

margins realized on each Fund. The Board noted that the Adviser is a wholly-owned subsidiary of Boston Trust and the payment of direct and indirect Trust expenses is governed by an Intercompany Services Agreement between the Adviser and Boston Trust. The Board noted that the Adviser’s relationship with the Funds was profitable even though the Adviser is operating under an Expense Limitation Agreement with the Trust.

Exhibit 99.CODEETH

BOSTON TRUST WALDEN FUNDS

CODE OF ETHICS FOR PRINCIPAL EXECUTIVE AND

PRINCIPAL FINANCIAL OFFICERS

Covered Officers/Purpose of the Code

The Boston Trust Walden Funds’ (the “Trust” or the “Funds”) code of ethics (this “Code”) applies to the Trust’s Principal Executive Officer (“President”) and Principal Financial Officer (“Treasurer”) (the “Covered Officers” each of whom are set forth in Exhibit A) for the purpose of promoting:

•

honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

•

full, fair, accurate, timely and understandable disclosure in reports and documents that a registrant files with, or submits to, the Securities and Exchange Commission (“SEC”) and in other public communications made by the Trust;

•

compliance with applicable laws and governmental rules and regulations;

•

the prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

•

accountability for adherence to the Code.

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.¹

¹Item 2 of Form N-CSR requires a registered management investment company to disclose annually whether, as of the end of the period covered by the report, it has adopted a code of ethics that applies to the registrant’s principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, regardless of whether these officers are employed by the registrant or a third party. If the registrant has not adopted such a code of ethics, it must explain why it has not done so. The registrant must also: (1) file with the SEC a copy of the code as an exhibit to its annual report; (2) post the text of the code on its Internet website and disclose, in its most recent report on Form N-CSR, its Internet address and the fact that it has posted the code on its Internet website; or (3) undertake in its most recent report on Form N-CSR to provide to any person without charge, upon request, a copy of the code and explain the manner in which such request may be made. Disclosure is also required of amendments to, or waivers (including implicit waivers) from, a provision of the code in the registrant’s annual report on Form N-CSR or on its website. If the registrant intends to satisfy the requirement to disclose amendments and waivers by posting such information on its website, it will be required to disclose its Internet address and this intention.

II.

Covered Officers Should Handle Ethically Actual and Apparent Conflicts of Interest

Overview. A “conflict of interest” occurs when a Covered Officer’s private interest interferes with the interests of, or his service to, the Trust. For example, a conflict of interest would arise if a Covered Officer, or a member of his family, receives improper personal benefits as a result of his position in the Trust.

Certain conflicts of interest arise out of the relationships between Covered Officers and the Trust and already are subject to conflict of interest provisions in the Investment Company Act of 1940 and the Investment Advisers Act of 1940. For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Trust because of their status as “affiliated persons” of the Trust. The compliance policies and procedures of the Trust and the investment adviser (the “Adviser”) are designed to prevent, or identify and correct, violations of these provisions. This Code does not, and is not intended to, repeat or replace these programs and procedures, and such conflicts fall outside of the parameters of this Code.

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between the Trust and the investment adviser of which the Covered Officers are also officers or employees. As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the Trust or for the investment adviser, or for both), be involved in establishing policies and implementing decisions which will have different effects on the investment adviser and the Trust. The participation of the Covered Officers in such activities is inherent in the contractual relationship between the Trust and the investment adviser and is consistent with the performance by the Covered Officers of their duties as officers of the Trust. Thus, if performed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, such activities will be deemed to have been handled ethically. In addition, it is recognized by the Board of Trustees (the “Board”) that the Covered Officers may also be officers or employees of one or more other investment companies covered by this or other Codes.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act. The following list provides examples of conflicts of interest under the Code, but Covered Officers should keep in mind that these examples are not exhaustive. The overarching principle is that the personal interest of a Covered Officer should not be placed improperly before the interest of the Trust.

* * * *

Each Covered Officer must:

•

not use his personal influence or personal relationships improperly to influence investment decisions or financial reporting by the Trust whereby the Covered Officer would benefit personally to the detriment of the Trust;

•

not cause the Trust to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than for the benefit of the Trust;

•

not use material non-public knowledge of portfolio transactions made or contemplated for the Trust to trade personally or cause others to trade personally in contemplation of the market effect of such transactions;

There are some conflict of interest situations that may be discussed with the Funds’ Legal Counsel, if material. Examples of these include:²

•

service as a director on the board of any public or private company;

•

the receipt of any non-nominal gifts;

•

the receipt of any entertainment from any company with which the Trust has current or prospective business dealings unless such entertainment is business- related, reasonable in cost, appropriate as to time and place, and not so frequent as to raise any question of impropriety as consistent with the Funds’ Code of Ethics;

•

any ownership interest in, or any consulting or employment relationship with, any of the Trust’s service providers, other than its investment adviser, subadviser, principal underwriter, administrator or any affiliated person thereof;

•

a direct or indirect financial interest in commissions, transaction charges or spreads paid by the Trust for effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Covered Officer’s employment, such as compensation or equity ownership.

III.

Disclosure & Compliance

•

Each Covered Officer should familiarize himself with the disclosure requirements generally applicable to the Trust;

•

each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about the Trust to others, whether within or outside the Trust, including to the Trust’s directors and auditors, and to governmental regulators and self-regulatory organizations;

•

each Covered Officer should, to the extent appropriate within his area of responsibility, consult with other officers and employees of the Trust and the Trust’s adviser or subadviser with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Trust files with, or submit to, the SEC and in other public communications made by the Trust; and

Any activity or relationship that would present a conflict for a Covered Officer would likely also present a conflict for the Covered Officer if a member of the Covered Officer’s family engages in such an activity or has such a relationship.

•

it is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

IV.

Reporting and Accountability

Each Covered Officer must:

•

upon adoption of the Code (or thereafter as applicable, upon becoming a Covered Officer), affirm in writing to the Board that he has received, read, and understands the Code (Exhibit B – Initial Certification);

•

annually thereafter affirm to the Board that he has complied with the requirements of the Code (Exhibit C – Annual Certification);

•

not retaliate against any employee or Covered Officer or their affiliated persons for reports of potential violations that are made in good faith;

•

notify the Funds’ Legal Counsel promptly if he knows of any violation of this Code. Failure to do so is itself a violation of this Code; and

•

report at least annually any change in his affiliations from the prior year.

The Funds’ Legal Counsel is responsible for applying this Code to specific situations in which questions are presented under it and has the authority to interpret this Code in any particular situation. However, any approvals or waivers³ sought by the Principal Executive Officer will be considered by the Audit Committee (the “Committee”).

The Trust will follow these procedures in investigating and enforcing this Code:

•

the Funds’ Legal Counsel will take all appropriate action to investigate any potential violations reported to him;

•

if, after such investigation, the Funds’ Legal Counsel believes that no violation has occurred, the Funds’ Legal Counsel is not required to take any further action;

•

any matter that the Funds’ Legal Counsel believes is a violation will be reported to the Committee;

•

if the Committee concurs that a violation has occurred, it will inform and make a recommendation to the Board, which will consider appropriate action, which may include review of, and appropriate modifications to, applicable policies and procedures; notification to appropriate personnel of the investment adviser or its board; or a recommendation to dismiss the Covered Officer;

Item 2 of Form N-CSR defines “waiver” as “the approval by the registrant of a material departure from a provision of the code of ethics” and “implicit waiver,” which must also be disclosed, as “the registrant’s failure to take action within a reasonable period of time regarding a material departure from a provision of the code of ethics that has been made known to an executive officer” of the registrant.

•

the Committee will be responsible for granting waivers, as appropriate; and

•

any changes to or waivers of this Code will, to the extent required, be disclosed as provided by SEC rules.

V.	Other Policies and Procedures

This Code shall be the sole code of ethics adopted by the Funds for purposes of Section 406 of the Sarbanes- Oxley Act of 2002 and the rules and forms applicable to registered investment companies thereunder. Insofar as other policies or procedures of the Funds, the Funds’ adviser, principal underwriter, or other service providers govern or purport to govern the behavior or activities of the Covered Officers who are subject to this Code, they are superceded by this Code to the extent that they overlap or conflict with the provisions of this Code. The Funds’ and their investment adviser’s, principal underwriter’s and service providers’ codes of ethics under Rule 17j-1 under the Investment Company Act and the adviser’s more detailed policies and procedures are separate requirements applying to the Covered Officers and others, and are not part of this Code.

VI.

Amendments

Any amendments to this Code, other than amendments to Exhibit A, must be approved or ratified by a majority vote of the Trust’s board, including a majority of independent directors/trustees.

VII.

Confidentiality

All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the appropriate Board and its counsel, the investment adviser and the administrator.

VIII.

Internal Use

The Code is intended solely for the internal use by the Funds and does not constitute an admission, by or on behalf of any Company, as to any fact, circumstance, or legal conclusion.
