Writing on governance, risk, compliance and audit since 2020

Managers handle the corporation's day-to-day activities, while the board handles planning and oversight. The investment committee follows the same division responsibilities, overseeing investment decisions while management handles implementation.

The chief investment officer (CIO) and staff in the investment department handle day-to-day management of the corporation’s investment portfolio, while the investment committee handles planning and oversight.

Just as the board takes responsibility for poor decisions and negative results, the investment committee is responsible for poor investment decisions and outcomes.

The investment committee approves the fund’s investment objectives. The committee must develop an investment plan in line with the corporation’s financial needs and circumstances.

According to What Directors Think 2026 by Diligent Institute and Corporate Board Member, 42% of surveyed U.S. public company directors expect technology adoption and integration to receive the most capital investment in 2026. For investment committees, that concentration of capital increases the need to test proposals against corporate priorities, total cost, expected value and risk tolerance.

This guide explains how investment committees operate across corporate, nonprofit, endowment and retirement-plan settings:

  • What an investment committee is and its primary responsibilities
  • How the committee works with the board, chief investment officer and advisors
  • How the charter, investment policy statement and fiduciary duties shape governance
  • How technology and repeatable processes support committee decisions and records

What is an investment committee?

An investment committee is a formal governance body responsible for overseeing an organization’s investment policies, strategy and portfolio performance on behalf of the organization or its beneficiaries. The committee provides governance and oversight, while staff, advisors or external managers handle day-to-day portfolio management.

Committees of this kind oversee many asset types, including corporate funds, nonprofit reserves, university endowments, foundation assets, pension funds and 401(k) or 403(b) plans. A CFA Institute digest of Charles D. Ellis’s research on best-practice committees says an endowment committee defines and reviews investment policy and organizational governance, while staff or managers handle investment management.

Role of the chief investment officer

The CIO is the primary liaison between the investment committee and the investment staff regarding the corporation’s investment strategy. A qualified CIO builds a cohesive approach to investment strategy and can secure agreement between the committee and staff on direction and expectations.

The committee functions best when that relationship is one of trust. Operating policies should state plainly which decisions the CIO can make and which require committee approval, so neither side has to guess where authority sits.

Duties and responsibilities of the investment committee

Several factors may indicate the investment committee's success. These include the committee’s composition and its members’ skills and abilities. Its approach to developing objectives, policies and practices also matters. These factors will be spelled out in the committee’s charter.

Committee size and composition

The size of investment committees generally reflects the size of the investment plan. Smaller organizations with small investment plans may have as few as three people on the investment committee, whereas larger organizations with large investment plans may have five or more. It’s best for investment committees to have an odd number of members to avoid ties in voting.

A committee can include members with and without financial expertise. Every member needs enough time for committee work and the ability and willingness to support the statement of investment policies. Committee members should bring a diverse set of perspectives and a willingness to collaborate and be open. Boards typically rotate members into the investment committee to avoid burnout.

Core responsibilities of an investment committee

Whatever its size and makeup, the committee’s core work looks similar across corporate, nonprofit and retirement-plan settings. At a minimum, an investment committee should:

  • Set and periodically review investment objectives
  • Approve and review the investment policy statement
  • Establish risk tolerance, asset-allocation ranges and performance benchmarks
  • Select, monitor and, when necessary, terminate external investment managers and advisors
  • Monitor performance, fees, compliance and material exceptions
  • Document decisions, conflicts, votes and the rationale for significant actions

Fiduciary duties of committee members

How strictly the law holds members to that work depends on the context. Nonprofit and endowment committee members typically owe the same fiduciary duties as other board members. These duties include care and loyalty. Members also owe a duty of obedience. State law adds detail here; UPMIFA, the uniform act governing how charitable institutions manage donated funds, makes the duty of care mandatory for those overseeing institutional funds.

Retirement plans operate under a different regime. The U.S. Department of Labor’s fiduciary guidance explains that the test for fiduciary status is whether a person exercises discretion or control over the plan, and committee members who do must act prudently and solely in the interest of participants and beneficiaries. Which standard applies turns on the organization’s legal form and the assets involved, so committees should confirm their obligations for their specific structure.

Establishing objectives and policies

The investment committee is the primary authority for developing the corporation’s investment objectives and investment policies. Some organizations allow the committee to make decisions and others allow it to delegate them to consultants or other designated firms or individuals. The committee ultimately shoulders the responsibility for those decisions either way.

Operating policy and delegated authority

The investment committee first adopts a written operating policy. It defines the committee’s membership and meeting procedures, including attendance. Committee members also decide how they will get information from investment staff and how they’ll feed information up to the board. Operating policies clearly define the CIO's duties and powers and specify which actions require committee approval.

Charter versus investment policy statement

Two documents anchor this work, and they do different jobs. The investment committee charter defines the committee’s purpose, the authority the board has delegated to it, membership, meeting procedures, reporting lines and the thresholds at which a decision must return to the full board.

The statement of investment policies governs the money itself: return objectives, risk tolerance, permitted investments, asset-allocation ranges, liquidity needs and the benchmarks against which performance will be judged. Investment policy statements usually include one or more benchmark portfolios that serve as metrics for evaluating portfolio returns over several years.

Treating the two documents as interchangeable can leave gaps in both the committee’s authority and its investment discipline. The investment policy statement also requires periodic review. Commonfund advises annual board review to help the statement remain “an appropriate distillation of the institution’s investment philosophy and practice.”

Meeting minutes as evidence of due diligence

Meeting minutes are an important part of the investment committee’s responsibilities. Minutes prove that the committee conducted its duties with due diligence in decision-making. They also provide a historical reference that guides future discussions and forms a base for future decisions. Minutes should include a list of attendees, the topics discussed, actions, decisions and processes, as well as describe the committee’s rationale in forming decisions.

Formalize the mandate

Use Diligent’s sample investment committee charter to define authority, membership, meeting procedures and reporting responsibilities.

Assigning responsibility for investment strategies

Organizations have several options for assigning responsibility for implementing investment strategies. Size is a major factor in choosing a structure that meets the organization’s needs.

Organizations may hire and retain investment managers or delegate the responsibility to the CIO and staff. Investment committees usually rely on the CIO's recommendations when selecting specific investment management firms.

The committee retains accountability after delegating implementation. When the committee hands implementation to an outside manager or advisor, it should document the mandate in writing, monitor performance and fees against the agreed benchmarks regularly and retain clear authority to replace the advisor or manager when performance, compliance or service no longer meets policy.

For ERISA-covered retirement plans, the same Department of Labor guidance states that even after functions are handed off, the fiduciary “retains the responsibility for selecting and monitoring the investment alternatives that are made available under the plan.”

Working with the CIO and investment staff

Investment committees must recognize that the CIO and investment staff are the primary sources of the latest information on investment strategies. Their daily work in the field is the best resource for continuing education and perspective for committee members. The employees who work in the investing department are also best positioned to help the committee follow best practices and to set realistic expectations for returns and volatility.

Investment staff should be able to relate every recommendation back to the corporation’s investment policies. Staff should also be aware of attractive opportunities that don’t line up exactly with those policies.

When pursuing such opportunities, committee members need to conduct due diligence to prevent unnecessary or disastrous risks, and staff should temper enthusiasm for growth with careful explanations of their findings. Well-documented exceptions can add useful diversification to the overall portfolio.

Investment staff should also track how organizations of similar size and profitability invest their funds and how those funds perform relative to one another.

Balancing accountability across the board, committee and staff

The investment committee is responsible for the actions and decisions of the CIO and staff, while the board is responsible for the actions and decisions of the investment committee. Each group checks and balances the others. The success or failure of the corporation’s finances has a direct impact on many parts of the business, including competitive value, operational quality, growth potential, employment stability and shareholder value.

Investment risk also rarely sits in isolation from the rest of the risk register, which is why committees increasingly coordinate with finance, audit and risk functions rather than working alone. “Cross-functional coordination is key for operating in a world where top risks are interdependent and self-amplifying,” says Kira Ciccarelli, Senior Manager of Research, Diligent Institute.

Short-term losses do not necessarily indicate a flawed strategy, and short-term gains do not confirm a sound one. Boards and investment committees need to evaluate fund performance over long periods against multi-year benchmarks.

Sustaining that long-horizon discipline requires information to move reliably between staff and the committee, then from the committee to the board. That flow is not yet the norm: What Directors Think 2026 found that 47% of directors receive real-time data often or always.

“Looking ahead, high-performing boards will treat governance as a continuous discipline, built on real-time data flows rather than periodic reports,” says Dottie Schindlinger, Executive Director, Diligent Institute, in What Directors Think 2026, published with Corporate Board Member.

“And they will increasingly rely on integrated digital platforms — and, over time, AI-driven analytics — to surface patterns, flag emerging risks and point directors to where their judgment is needed most, while keeping human decision-making firmly at the center.”

How AI transforms investment committee governance

The documentation and information-flow challenges described above affect preparation, secure deliberation and defensible records. Diligent Boards is AI-powered board management software that addresses those administrative demands while leaving investment selection and fiduciary judgment with the committee.

For committees whose materials are still scattered across email and shared drives, Document Library centralizes charters, investment policy statements, meeting materials and minutes in one secure location, so members work from the current version of each document. SmartPrep generates source-cited questions from those materials, which helps members arrive ready to examine recommendations, assumptions and policy alignment rather than reading for the first time in the room.

For committees that need a formal record of how members acted, Board Messaging keeps sensitive communications in a protected channel rather than personal email, and e-signature and voting, with full audit trails, support approvals and dissents. Smart Minutes supports the meeting records used to demonstrate due diligence, while Action Tracker converts decisions into assigned follow-up between meetings.

AutoZone replaced printed board books and email attachments with a centralized portal using Diligent Boards, giving directors a single, secure place to work from.

Together, these capabilities connect preparation and deliberation to documented action, without positioning software as an investment manager or performance-measurement tool. A practical first step is to map the committee’s current workflow to identify fragmented documents, scattered communications and gaps in action records.

Frequently asked questions about investment committees

What does an investment committee advisor do?

An investment committee advisor provides market and asset-class research, portfolio analysis, manager due diligence and recommendations on strategy and allocation. The committee remains responsible for approving policy, monitoring performance and fees and deciding whether to continue the relationship, including when the advisor implements decisions through an outsourced CIO arrangement.

What steps belong in an investment committee process?

A repeatable process starts by defining objectives and translating them into an approved investment policy statement. The committee then reviews recommendations, records its decisions and rationale and monitors results, fees and policy exceptions. It revisits the policy on a set cycle as the organization’s circumstances change.

How often should an investment committee meet?

Quarterly meetings are a common baseline because they align with manager and custodian reporting cycles. Frequency should reflect asset complexity, delegated authority and market or organizational events. Committees overseeing a transition or volatile conditions may meet more often, while delegated arrangements may support fewer formal meetings when the charter and applicable duties permit.

How does a private equity investment committee differ?

A private equity investment committee typically approves proposed transactions by examining the investment thesis, assumptions, valuation, risk, conflicts and exit scenarios. Corporate, nonprofit and endowment committees generally focus on policy, asset allocation and manager oversight, so they should not adopt the deal-approval model unless their mandate specifically requires it.

How should an investment committee measure performance?

Measure performance against the benchmarks in the investment policy statement and consider risk-adjusted returns, fees and liquidity alongside headline results. Evaluation should cover appropriate multi-year periods, because short-term volatility can distort long-term performance and prompt a committee to abandon a sound strategy after one poor quarter.
