Boston Trust Asset Management Fund Boston Trust Equity Fund December 31, 2023 Amy Crandall Kaser, CFP® Co-Portfolio Manager Jason T. O’Connell, CFA, CAIA, CFP® Co-Portfolio Manager Boston Trust Walden Inc. 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 closed a strikingly strong year with most of the primary indices registering gains well into the double-digits in 2023. The S&P 500 Index led the way with a more than 26% return for the calendar year. The Index’s impressive gains were driven, in large part, by just a small group of technology-oriented companies thought to have outsized growth prospects well into the future. Dubbed the Magnificent Seven by the financial media, the group consists of Alphabet (Google) Amazon, Apple, Meta (Facebook), Microsoft, Nvidia, and Tesla. At points during the year, those seven companies accounted for a near 30% weight in the S&P 500 and thoroughly dominated its performance to the extent that they were collectively responsible for 99% of the Index’s return through the month of October. Notably, the average stock in the Index had a far different experience, advancing a still healthy but comparatively mild 13.8% for the year. Gains became far more broad-based later in the year, with a larger, more diverse set of businesses taking part in the continued market rally. The bond market experienced volatility throughout the year, precipitated by the Federal Reserve’s aggressive policy maneuvers to curb inflation. However, the moves in US government bond yields largely amounted to a round trip by year-end, meaning that investors holding such bonds throughout the period earned a return approximately equal to the income. The broader bond markets, which include non-government securities, fared better as investors were compensated for taking on credit risk that began to appear less severe amidst stronger than anticipated economic data and an end to rate increases by the Federal Reserve. Boston Trust Asset Management Fund and Boston Trust Equity Fund Both delivered substantial but comparatively muted gains in 2023. For the full year, the Funds' values advanced 13.72% and 17.29%, respectively. During the year, the Boston Trust Asset Management Fund's performance was supported by its higher-than-average allocation to equities. However, while the equity holdings in both funds delivered strong absolute returns, on average, those securities trailed the S&P 500 benchmark given the team’s decision not to veer from its diversification and valuation disciplines. Similarly, the relatively conservative tack taken in the Boston Trust Asset Management Fund's fixed income segment led to a positive result but did not meet the return of the broader indices, which generally carry more credit risk and interest rate sensitivity. We begin 2024 with improved business conditions versus a year ago: inflation is down, a historic interest hiking cycle is behind us, and the labor market and consumer spending remain reasonably healthy. Furthermore, the Federal Reserve’s indications that it may be in a position to reverse course to a more accommodative interest rate policy increases our confidence that the US has sidestepped a deep or prolonged recession. With that economic backdrop and the select availability of sound businesses whose shares do not imply overly optimistic outcomes, the Boston Trust Asset Mangement Fund’s asset allocation remains tilted in favor of equities. Of course, plenty of macroeconomic and geopolitical uncertainty remains. Therefore, the Fund’s fixed income segment is designed to play the important role of providing ballast against not only the inherent volatility in stocks but also should the presently benign economic conditions deteriorate, or an exogenous event undermine investor confidence.*   * Portfolio composition is subject to change.

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 Total Return 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 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 (e.g., agency, sovereign, supranational, and local authority debt), and USD Corporates. The Bloomberg U.S. Government/Credit Bond Index is a component of the Bloomberg U.S. Aggregate Bond Index. The FTSE 3-Month U.S. 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.

Boston Trust Midcap Fund December 31, 2023 Stephen J. Amyouny, CFA Lead Portfolio Manager Richard Q. Williams, CFA Co-Portfolio Manager Mark Zagata, CFA Co-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 Boston Trust Midcap Fund returned 13.05% in the calendar year 2023, trailing the Russell Midcap®Index return of 17.23%. The Adviser's analysis of the year suggests the Fund’s valuation discipline (which seeks to identify the stocks of companies that are reasonably valued) detracted from performance results. Outlook The valuation of the mid cap market (as measured by the Russell Midcap®Index price-to-earnings ratio) as of the end of 2023 was approximately in line with historical averages. The Adviser believes that pockets of speculative valuation exist, however, and remain a risk. Further, index earnings may have reached a new record in 2023, and the increasingly supportive economic backdrop suggests this trajectory may continue in 2024. The Adviser believes that over the long-term, companies with stronger fundamentals generate superior returns. The Adviser believes that a well-diversified Fund comprised of reasonably valued stocks of higher quality companies will add value over full market cycles. A full market cycle includes one bear and one bull market.*   * Portfolio composition is subject to change.

Boston Trust SMID Cap Fund December 31, 2023 Kenneth P. Scott, CFA Lead Portfolio Manager Richard Q. Williams, CFA Co-Portfolio Manager Leanne Moore Co-Portfolio Manager Boston Trust Walden Inc. 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 Boston Trust SMID Cap Fund returned 13.14% in the calendar year 2023, trailing the Russell 2500™ Index return of 17.42%. Despite the strong absolute market return, analysis of the data suggests there was no evidence of a performance headwind due to the Fund’s investment style. Thus, the Adviser attributes the performance shortfall to unfavorable stock selection during the year, a contrast to the prior two years, when the Fund enjoyed style tailwinds and incrementally favorable performance of Fund holdings relative to the high quality opportunity set. Outlook The valuation of the small-mid cap market (as measured by the Russell 2500™ Index price-to-earnings ratio) as of the end of 2023 was approximately in line with historical averages. The Adviser believes that pockets of speculative valuation exist, however, and remain a risk. Further, index earnings may have reached a new record in 2023, and the increasingly supportive economic backdrop suggests this trajectory may continue in 2024.

Boston Trust Walden Balanced Fund Boston Trust Walden Equity Fund December 31, 2023 Balanced Fund Portfolio Management Stephen J. Amyouny, CFA Lead Portfolio Manager Tchintcia S. Barros, CFA Co-Portfolio Manager Sean A. Cameron, CFA Co-Portfolio Manager Equity Fund Portfolio Management Tchintcia S. Barros, CFA Lead Portfolio Manager Stephen J. Amyouny, CFA Co-Portfolio Manager Mark B. Zagata, CFA Co-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.   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 The Boston Trust Walden Balanced Fund and the Boston Trust Walden Equity Fund returned 12.18% and 16.29%, respectively for the 12-month period ended December 31, 2023. The relevant market indices, the S&P 500 Index and the Bloomberg U.S. Government/Credit Bond Index, returned 26.29% and 5.72%, respectively, for the year. The S&P 500 Index returned 26.29% in 2023, posting a strong return after delivering a -18.11% total return in the prior year. While the Funds’ valuation discipline provided downside protection in 2022, this valuation discipline weighed on relative performance in 2023 as more speculatively priced pockets of the equity market delivered outsized returns. Examining through an equity sector lens, information technology represented the sector exhibiting particular strength during the year. The market continued to favor information technology companies such as software-oriented businesses and semiconductor firms with strong growth prospects; in particular, companies with perceived leverage to the emerging artificial intelligence (AI) industry performed exceptionally well. For the full year, the three standout sectors were information technology, communication services, and consumer discretionary – three sectors that tend to exhibit attractive growth profiles. Conversely, energy and utilities – two of the more traditional value sectors — represented the two sectors that declined in total return terms in 2023. Overall, the Funds maintain broad diversification across several sectors and industries in the strategies’ holdings. The Balanced Fund’s high-quality focus within investment grade fixed income served as a detractor to relative performance in 2023 as lower quality credits generally outperformed higher quality fixed income securities. Nonetheless, as spreads on corporate bonds tightened, the Fund benefitted in absolute terms across its corporate bond holdings. Moreover, a primary determinant of fixed income returns is the interest rate sensitivity, or duration, of portfolio holding. The Balanced Fund maintained a below index duration relative to the Bloomberg U.S. Government/Credit Bond Index in the first half of the year and then increased the duration of the Fund to neutral in the second half of the year as it became clear the Federal Reserve was nearing the end of its hiking cycle. These moves have helped lock in more attractive fixed income yields priced at higher levels. Outlook The real US Gross Domestic Product increased by 2.5% in 2023, compared with an increase of 1.9% in 2022 and 6% in 2021. The probability of a recession within the next year still exists in response to the Fed’s commitment to getting inflation under control and pockets of stress in the banking sector weighing on consumer and business sentiment. Nonetheless, while we expect economic and corporate profit growth to moderate, we believe that present equity valuations largely reflect these expectations. We acknowledge, however, that the prospect of tighter financial conditions remains a powerful force and the unwinding of the US Federal Reserve's balance sheet may weigh on sentiment and near-term returns. Despite the modestly constructive outlook, we remain vigilant for risks. Among the most pressing are segments of the market that continue to exhibit elevated valuations, geopolitical and military risks that threaten global trade and stability, banking system stresses becoming more broad-based, and the potential for inflation to remain elevated longer term. This latter issue may hamper discretionary consumer spending as well as corporate profits for companies unable to pass along higher input prices. We remain focused on identifying and investing in a diversified portfolio of high-quality securities at reasonable valuations. We believe that this long-held discipline will allow the strategy to capitalize on our outlook for economic strength yet effectively navigate risks along the way, thereby achieving an attractive risk-adjusted return performance pattern over full market cycles.*   * Portfolio composition is subject to change.

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 Total Return 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 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 U.S. Government/Credit Bond Index is a component of the Bloomberg U.S. Aggregate Bond Index. The FTSE 3-Month U.S. 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.

The Adviser believes that pockets of speculative valuation exist, however, and remain a risk. Further, index earnings may have reached a new record in 2023, and the increasingly supportive economic backdrop suggests this trajectory may continue in 2024.   The Adviser believes that over the long-term, companies with stronger fundamentals generate superior returns.

Boston Trust Walden International Equity Fund December 31, 2023   Nathaniel J. Riley, CFA Co-Portfolio Manager   David A. Sandell, CFA Co-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, 2023, the Boston Trust Walden International Equity Fund posted a total return of 16.19%. The Fund’s return trailed its primary benchmark, the MSCI World ex-USA Index (net), which posted a return of 17.94% for the year.   International equity markets had a choppy year. After a strong start to 2023, the banking crisis, that began in the US with Silicon Valley Bank, quickly affected markets around the world. In addition to the concern around the health of banks and the banking system, investors also considered the broader effects of a possible financial crisis. But investors quickly regained confidence as central banks showed their willingness to protect against widespread contagion, and stocks rebounded. Later in the year, price inflation in many parts of the world, and the consequent monetary policy responses, weighed on equities. But this downturn also reversed when, in the final quarter of the year, inflation statistics showed a general deceleration and central banks indicated that they may soon begin to curtail their restrictive monetary policies. Such a move could benefit corporations and asset prices generally, and the market responded accordingly.   The rise in international markets was widespread. Of the 18 countries represented in the Fund, all but two had a positive return during 2023. Those two included Hong Kong, which suffered from China’s economic volatility through the year, and Norway, represented by a single Energy stock that was down slightly. Among sectors, all but one had a positive return during 2023 in the Fund, though there was a wide dispersion of returns across sectors. The Fund’s holdings within Real Estate sector fared the worst, with a decline of 4.5%, due to underperformance of Hong Kong real estate companies. Holdings in Information Technology performed best, with a rise of 34.0%, helped by strong performance of semiconductor equipment and software holdings.   Turning to other market dynamics, fundamental business quality, as measured by the Adviser’s proprietary metric, was a modest detractor to performance relative to the benchmark. Stocks with poor quality profiles outperformed those with average or high quality profiles during 2023. The quality factor is typically a driver of relative returns for the Fund since the Fund generally maintains a positive exposure on this factor relative to the benchmark.   Because the Fund is priced in US dollars, but its holdings are predominantly denominated in other currencies, the weakening US dollar during 2023 affected reported, USD-denominated, returns. While the MSCI World ex-USA Index (net) return in US dollars was 17.9% for the year, the same index’s return measured in local currency was 15.8%. The difference of 2.1% is due to the depreciation of the US dollar relative to the basket of currencies represented by the Index constituents. Because the Fund holdings represent roughly the same basket of currencies as the Index, the Adviser estimates that the Fund’s reported returns were affected by the dollar’s decline by a similar magnitude.*     * Portfolio composition is subject to change.

Notes to the Financial Statements December 31, 2023

1. 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	BTW Balanced Fund
Boston Trust Walden Equity Fund	BTW Equity Fund
Boston Trust Walden Midcap Fund	BTW Midcap Fund
Boston Trust Walden SMID Cap Fund	BTW SMID Cap Fund
Boston Trust Walden Small Cap Fund	BTW Small Cap Fund
Boston Trust Walden International Equity Fund	BTW International Equity Fund

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.

2. 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 current 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 Board has designated the Adviser as its fair valuation designee to perform fair value determinations for the Trust. The Trust may use one or more pricing services 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 net asset value (“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 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.

Notes to the Financial Statements December 31, 2023

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, 2023.

The following is a summary of the investments by valuation inputs used as of December 31, 2023 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 the trade date. However, for financial reporting purposes, investment transactions are accounted for on the 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:

In general, expenses uniquely attributable to a Fund are charged directly to that Fund. Expenses relating to the Trust, or on occasion certain minimum fees within Trust's fee structure, 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 relevant Fund. Dividends to shareholders from net realized gains, if any, are declared and distributed at least annually by the relevant Fund. 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.

68

Notes to the Financial Statements December 31, 2023

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, 2023. 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, 2023.

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:

i) 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.

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 (a portion of which may be reclaimable) 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. Withholding taxes and reclaims on foreign dividends have been provided for in accordance with the Funds’ understanding of the applicable country’s tax rules and rates.

3. 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 the year ended December 31, 2023. 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, one trustee of the Trust is an officer of the Trust and an officer of the Adviser. This person is not paid directly by the Funds.

Administration and Fund Accounting:

Effective October 2, 2023, the Northern Trust Company (“Northern Trust”) serves as the administrator and fund accounting agent for the Funds pursuant to a written agreement with the Trust on behalf of the Funds. The Funds have agreed to pay Northern Trust a tiered basis-point fee based on the Boston Walden Funds Trust’s complex level net assets, certain per account and transaction charges, other fees for additional service activities, and reimbursement of certain expenses.

Prior to October 2, 2023, Citi Fund Services Ohio, Inc. (“Citi”) served the Funds as administrator. Citi provided administrative and fund accounting services for a fee that was 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 Northern Trust or PINE Advisor Solutions (“PINE”). Such persons receive no compensation directly from the Funds for serving in their respective roles. PINE receives fees from the Funds for providing Chief Compliance Officer (“CCO”) services under a Services Agreement between the Funds and PINE (the “CCO Agreement”). Under the CCO Agreement, PINE provides infrastructure and support in implementing written policies and procedures comprising the Funds' compliance program, including support services to the CCO. For the services provided under the CCO Agreement, the Funds pay PINE $145,000 annually, plus certain out of pocket expenses. PINE pays the salary and other compensation earned by the CCO as an employee of PINE.

Shareholder Services:

Each Fund, other than the Boston Trust SMID Cap Fund, 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, 2023.

Custodian and Transfer Agency:

FIS Investor Services, LLC ("FIS") acts as the Funds' transfer agent. Under the transfer agency agreement, FIS receives $19,338 annually per fund, 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 are presented collectively as “Transfer Agency” expenses on the Statements of Operations.

Effective October 2, 2023, Northern Trust serves as the custodian for the Boston Trust Walden Funds pursuant to a written agreement with the Trust on behalf of the Funds. The Funds have agreed to pay Northern Trust a fee based on a percentage of assets held on behalf of the Funds, transaction fees and certain out of pocket expenses for its services. Such percentages vary by the jurisdiction in which the assets are held.

Prior to October 2, 2023, Boston Trust Walden Company acted as the custodian for all Funds except the BTW International Equity Fund. Under the custody agreement, Boston Trust Walden Company received an annual asset based fee of 0.014% of the value of securities held. Citibank, N.A. received sub-custodian fees from Boston Trust Walden Funds for each Fund except the BTW International Equity Fund. Under a separate custody agreement, Citibank, N.A., an affiliate of Citi, served as custodian for the BTW International Equity Fund and received 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. Any such 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, 2021 (expiring 12/31/24), December 31, 2022 (expiring 12/31/25) and December 31, 2023 (expiring 12/31/26):

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 Assets and Liabilities. As of December 31, 2023, the Funds had no outstanding loans to or from another fund under the Program. The Funds' activity in the Program during the year ended December 31, 2023 for which loans were outstanding was as follows:

Fund	Borrower or Lender	Weighted Average Loan Balance		Days Outstanding			Weighted Average Annualized Interest Rate			Interest Income (Expense)
Asset Management Fund	Lender	$	455,736		1			6.95	%	$	87

¹ Accumulated Capital and Other Losses consists primarily of capital loss carryforwards and losses on foreign currency. The differences between book-basis and tax-basis unrealized appreciation (depreciation) is attributable primarily to tax deferral of losses on wash sales.

For the period subsequent to October 31, 2023, through the fiscal year ended December 31, 2023, the Equity Fund, Midcap Fund, and BTW Midcap Fund incurred net capital losses in the amount of $59,871, $213,652 and $179,670, respectively, which the Funds intend to treat as having been incurred in the following fiscal year.

As of the end of its tax year ended December 31, 2023, the following Funds have a net capital loss carry forwards (“CLCFs”) not subject to expiration as summarized in the table below. The Board does not intend to authorize a distribution of any realized gain for the Funds until any applicable CLCFs have been offset.

Fund	Short-Term Amount		Long-Term Amount		Total
SMID Cap Fund	$	774,957	$	—	$	774,957
BTW Small Cap Fund		1,193,497		7,120,433		8,313,930
BTW International Equity Fund		445,109		1,743,384		2,188,493

As of December 31, 2023, the following reclassifications have been made on the Statements of Assets and Liabilities to increase (decrease) such accounts with offsetting adjustments as indicated:

Fund	Total Distributable Earnings			Paid in Capital
Asset Management Fund	$	(4,521,290	)	$	4,521,290
Equity Fund		(101,500	)		101,500
Midcap Fund		(61,791	)		61,791
SMID Cap Fund		1			(1	)
BTW Balanced Fund		(1,169,650	)		1,169,650
BTW SMID Cap Fund		(2	)		2
BTW International Equity Fund		4,768			(4,768	)

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.

6. 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, 2023, 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	U.S. Bank, N.A.		88.24	%

In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds, as of December 31, 2023, the results of their operations for the year then ended, the changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

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, 2023, 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. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Funds’ auditor since 2008.

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, 2022 through December 31, 2023.

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.

	Beginning Account Value 7/1/23		Ending Account Value 12/31/23		Expenses Paid During Period 7/1/23 - 12/31/23*		Annualized Expense Ratio During Period 7/1/23 - 12/31/23

BTW International Equity Fund		1,000.00		1,064.00		4.73		0.91

* 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.

Other Information:

A description of the policies and guidelines that the Funds use to determine how to vote proxies related to portfolio securities is available: (i) without charge, upon request, by calling 1-800-282-8782 ext. 7050, and (ii) on the Securities and Exchange Commission’s (the “Commission”) website at http://www.sec.gov.

Proxy voting policies and guidelines as well as information regarding how the Funds voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available (i) without charge, upon request, by calling 1-800-282-8782 ext. 7050, (ii) online at https://www. bostontrustwalden.com/investment-services/mutual-funds/; and (iii) on the Commission’s website at http://www.sec.gov.

The Funds’ Schedules of Portfolio Investments will be available no later than 60 days after each period end, without charge, online at https://www. bostontrustwalden.com/investment-services/mutual-funds/.

Liquidity Risk Management Program:

The Funds have adopted and implemented a written liquidity risk management program as required by Rule 22e-4 (the “Liquidity Rule”) under the Investment Company Act. The program is reasonably designed to assess and manage each Fund’s liquidity risk, taking into consideration, among other factors, each respective Fund’s investment strategy and the liquidity of its portfolio investments during normal and reasonably foreseeable stressed conditions; its short and long-term cash flow projections; and its cash holdings and access to other funding sources.

During the fiscal year ended December 31, 2023, the Trust’s Liquidity Risk Management Program Administrator (the “Program Administrator”) reviewed the Funds’ investments and determined that the Funds held adequate levels of cash and highly liquid investments to meet shareholder redemption activities in accordance with applicable requirements. Accordingly, the Program Administrator concluded that (i) the Funds’ liquidity risk management program is reasonably designed to prevent violations of the Liquidity Rule and (ii) the Funds’ liquidity risk management program has been effectively implemented.

Section 15 of the Investment Company Act of 1940 (the “1940 Act”) requires that the Investment Advisory Agreement with the Adviser be renewed annually by the Board 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 29, 2023. The Board requested, and the Adviser provided, information and data relating to: (i) the investment performance of each Fund 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 29, 2023, 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, and performance peer group and expense peer group information constructed by ISS/Strategic Insight ("ISS"). 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, type of clients, ESG integration, portfolio construction process and equity and fixed income approach. The Board discussed the Adviser’s approach to sustainable, responsible and impact investing, including its ESG 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 it effects 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, 2023, comparing each Fund's performance to a performance peer group constructed by ISS and the performance of the relevant Morningstar Category. The Board noted that as of June 30, 2023, 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 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 28, 2023 meeting, the Board concluded that the advisory fees and expense ratios were reasonable.

Investment Adviser Contract Approval (Unaudited) December 31, 2023

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, 2022 and the six-months ended June 30, 2023, 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 Walden. 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. The Board discussed the custody and transfer agency fees earned by the Adviser for services provided to the Funds, which are reduced by amounts paid for sub-custodian services.
