Boston Common was founded in 2002 by Geeta B. Aiyer, CFA, who remains the largest employee shareholder. Boston Common is registered with the United States Securities and Exchange Commission as an investment adviser that provides discretionary investment management services in the areas of equity and balanced accounts to a variety of clients. Clients include charitable organizations, pension and profit-sharing plans, state entities, taxable and tax- exempt institutional clients, high net worth individuals, commingled investment vehicles and mutual funds. All client portfolios are constructed with the aim of being consistent with the client’s objectives and risk tolerances. Boston Common also provides investment advisory services through wrap accounts sponsored by other investment advisers or broker- dealers, and in the form of an ESG model portfolio that third-party, unaffiliated advisers license, and may use to make investment decisions on their clients’ behalf. Boston Common integrates Environmental, Social and Governance (“ESG”) criteria into its investment process (as described below). Over the years, Boston Common has developed an extensive global network of contacts, including non-governmental organizations, regional social investment organizations, corporate social responsibility practitioners, social justice organizations and industry associations, which assist the firm in obtaining primary information on corporate activities in a wide range of locations. The firm also uses third-party ESG research providers in its stock selection process and may rely on this research in determining whether a particular company is in accordance with its clients’ or firms’ ESG guidelines. Through company dialogue and the shareholder resolution process, Boston Common voices shareowner concerns to management of select portfolio companies as part of the firm’s efforts to encourage them towards greater transparency, accountability, and commitment to ESG issues. Clients with portfolios containing assets greater than certain thresholds established by Boston Common may customize the specific ESG guidelines that are applied to their portfolios. A.

D. Other Sponsored Advisory Accounts Boston Common offers investment advisory services on a discretionary basis to clients of sponsoring broker-dealers or financial consultants who offer comprehensive brokerage, custodial and advisory services for a comprehensive “wrap fee,” which is typically based on the amount of client assets under management. The sponsors of these wrap programs remit a portion of the fees to Boston Common. Boston Common’s fees for providing investment advisory services to the sponsored accounts range from 0.7% to 1.0% of the assets that have been allocated to it for management. This range is determined between Boston Common and the sponsoring broker-dealer or financial consultant. In these arrangements, Boston Common makes decisions regarding what securities should be bought and sold for the wrap client’s account; the wrap sponsor selects the brokers that will effectuate the transactions. Boston Common is required to direct all brokerage transactions to the sponsoring broker- dealer. Execution prices are often less favorable than execution prices achieved in non-wrap accounts. Generally, Boston Common may terminate its participation in a wrap program upon thirty days’ notice. Please refer to Item 12 for a more complete discussion of the effects of Directed Brokerage.
