Acropolis Investment Management, LLC is a fee-only wealth management firm and has been providing advisory services since 2002. Our advisory services are described below. Our Advisory Services. We provide financial advisory and investment management services to:
• Individuals (including trusts and estates);
• Institutional clients including corporations, banks, insurance companies, labor organizations, university endowments, charitable organizations and other business entities;
• Company sponsored retirement plans; and
• Multiemployer and other retirement plans for members of labor organizations. Individual Investment Management Services. We assist individual investors in formulating their investment objectives, policies and constraints in order to develop individual investment programs. To develop a client's investment program, we first conduct an initial client interview to obtain detailed financial information and other relevant data to determine the appropriate investment guidelines, risk tolerance and other factors pertinent to the client's current financial situation and objectives. Once we have an understanding of the client's investment objectives, investment time horizon and risk tolerance, we develop a recommended investment program to meet their stated goals. The investment program is detailed in an Investment Policy Statement, which we discuss and review with the client, and require the client to sign, prior to making the initial investments. We generally have full trading discretion for our individual investment management services. The primary investments we employ in the management of client portfolios include individual stocks, bonds, exchange-traded funds and products that are managed by third parties such as mutual funds and separately managed accounts. However, depending upon a client's preferences and our recommendations, other types of investments may be used if deemed suitable for the client and not otherwise restricted by the client as outlined in the client’s Investment Policy Statement. Sub-Advisor Selection. While not a core component of our investment advisor business, we may from time to time assist in selecting a sub-advisor if a client desires a specific strategy not offered by Acropolis. Sub-advisors will have the same authority in management, including fee deduction, as is provided to Acropolis. All fees paid by client to Acropolis are exclusive and in addition to the fees paid to the sub-advisor. Page 5 of 18 Institutional Advisory Services. We provide institutional clients with portfolio management services that include fixed income only securities, equity only securities and blended portfolios of equities and fixed income. These services are available for financial institutions, not-for-profit organizations, pension funds, insurance companies, corporate operating accounts,

family offices, operating accounts, health and welfare funds, trustee directed defined contribution plans and defined benefit plans and endowment accounts. The execution of these services may be provided on a fully discretionary or non-discretionary basis depending upon the objectives of the institution. Company Sponsored Retirement Plan Advisory Services. Through our Acropolis Retirement Plan Solutions and Ullico Retirement Solutions programs, we provide investment advice to various company and union sponsored retirement plans such as 401(k) plans. As a fiduciary adviser, we assist the plan sponsor with the selection of the investment line-up for plan participants and provide corresponding general information materials and educational sessions to plan participants to enable each participant to direct the investment selection for his or her own plan retirement account. Where we agree to act as a fiduciary solely under ERISA Section 3(21), we do not take discretionary control over the investment selections for the plan, and the plan sponsor makes all decisions regarding the selection of the investment line-up for the plan. Where we agree to act as a fiduciary under ERISA Section 3(38), we have the discretion to implement and/or change any selection for the investment line-up for the plan. In all cases, we have no authority to make investment decisions on behalf of plan participants. Upon request, we will also meet or speak with participants on an individual basis to provide investment education. Ullico Retirement Solutions. Defined contribution (DC) retirement plans are now complementing many traditional defined benefit (DB) plans in the union workforce. Ullico Retirement Solutions (URS), a dba of Acropolis Investment Management, was created to provide defined contribution solutions as well as individual investment management services to the union workplace. The description of services provided for each are the same as already described. The defined contribution service may be delivered as a sub-advisory or solicitor’s relationship with Ullico Investment Advisors (UIA), an SEC registered investment advisor. Individual investment services are delivered through a solicitor’s agreement with UIA. See Item 19 of this ADV for additional detail on the solicitor’s agreement with UIA. Assets under Management. As of December 31, 2023, Acropolis managed or supervised assets totaling $1,921,770,519 on a discretionary basis and $28,033,768 on a non-discretionary basis. In addition, Acropolis also provides investment advice to 29 company sponsored retirement plans with over $452 million in plan assets. Our Principal Owners. We are owned by six management employees, who we refer to as our "partners." Our two principal owners, each of whom owns between 25% and 50% of Acropolis, are Christopher B. Lissner and David B. Ott.
