Fiduciary

Title: Fiduciaries — What They Are, Key Duties, Practical Steps for Acting (or Hiring One), and Regulatory Context

Introduction
A fiduciary is a person or organization legally and ethically required to act in the best interests of another party (the principal or beneficiary). Fiduciary relationships most often involve financial stewardship—managing another’s money, property, or decisions—but can also cover guardianship, executorship, and corporate governance. Fiduciaries owe heightened duties of care, loyalty, and good faith; failure to meet those duties can lead to civil liability for fiduciary negligence or breach.

Fast Fact
The “prudent person” standard for fiduciaries traces to Harvard College v. Amory (1830) and was modernized in many U.S. states by the Uniform Prudent Investor Act (1994), which emphasizes prudence, diversification, suitability, and risk/return considerations.

Key Takeaways
– A fiduciary must put the principal’s interests ahead of their own.
– Common fiduciaries: trustees, executors, guardians, attorneys, corporate directors, investment advisers.
– Core fiduciary duties: duty of care, duty of loyalty, duty to act in good faith.
– Investment fiduciaries follow additional guidelines and may face overlapping regulatory regimes (e.g., SEC Regulation Best Interest, suitability rules).
– Being a fiduciary carries legal exposure; fiduciary insurance and sound processes mitigate risk.

Who Can Be a Fiduciary? (Examples)
– Trustee and beneficiary (trust administration)
– Executor of an estate and legatee
– Guardian and ward (minor or incapacitated adult)
– Attorney and client (in many professional contexts)
– Agent and principal (when acting under a power of attorney)
– Corporate board members and shareholders (directors are trustees for shareholders in many respects)
– Investment advisers managing client assets

The Three Core Fiduciary Duties
1. Duty of Care
– Make informed, reasonable decisions after appropriate investigation.
– For boards: conduct due diligence, consider alternatives, and document deliberations.
– For investment fiduciaries: research investments, consider diversification, weigh risk vs. return.

2. Duty of Loyalty
– Put the principal’s interests first; avoid conflicts of interest.
– Disclose and, where appropriate, eliminate or obtain informed consent for conflicts.
– Do not profit from the relationship without explicit consent.

3. Duty to Act in Good Faith (and Duty of Obedience)
– Act honestly and within the scope of the authority given by the principal or governing documents (e.g., trust terms, corporate bylaws).
– Follow applicable laws and the intentions of the grantor/beneficiary.

Practical Steps for Fiduciaries — A Four-Step Framework
Step 1: Organize (Prepare and Know Your Role)
– Gather documents: trust/estate instruments, corporate bylaws, account statements, investment policy statements (IPS).
– Identify beneficiaries, heirs, stakeholders, and any time-sensitive obligations (tax filings, distributions, reporting).
– Assess asset mix, liquidity needs, legal constraints, and tax considerations.

Step 2: Formalize (Create Clear Policies & Agreements)
– Adopt or update an Investment Policy Statement (IPS) that documents objectives, risk tolerance, time horizon, constraints, and permitted investments.
– Create a conflict-of-interest policy and disclosure process.
– Document delegation: if you hire advisors, use written engagement letters that specify duties, compensation, and scope.
– For boards and trustees: maintain meeting minutes and written resolutions.

Step 3: Execute (Act Prudently and Document)
– Implement the IPS: select investments consistent with objectives and constraints.
– Use appropriate processes for hiring advisors/vendors (RFPs, references, background checks).
– Obtain informed consent for any transaction that raises potential conflicts.
– Keep clear, dated records of decisions, analyses, and communications with beneficiaries.

Step 4: Monitor (Ongoing Supervision & Reporting)
– Quarterly or semiannual reviews of portfolio performance vs. benchmarks and IPS objectives.
– Periodic rebalancing and reassessment of investment policy when circumstances change.
– Annual reporting to beneficiaries or shareholders that explains performance, fees, and material actions.
– For delegations, supervise delegates and review their work and compliance.

Investment Fiduciary Guidelines — Practical Items
– Diversify unless documented reasons not to.
– Match investments to the beneficiary’s objectives and liquidity needs.
– Consider total costs (management fees, transaction costs, tax impacts).
– Keep a contemporaneous rationale for major investment decisions.
– Avoid speculative or self-dealing transactions unless fully disclosed and authorized.

Regulatory Context and Important Distinctions
– Regulation Best Interest (Reg BI): Adopted by the SEC in 2019, Reg BI requires broker-dealers to act in a retail customer’s “best interest” when making recommendations, but it is not identical to the classic fiduciary standard that binds investment advisers under the Investment Advisers Act of 1940. Reg BI establishes four obligations (disclosure, care, conflict of interest, compliance) to raise broker conduct standards. (See SEC Reg BI release for details.)
– Investment advisers registered under the Investment Advisers Act are fiduciaries and owe an overarching duty of loyalty and care to clients.
– The DOL fiduciary rule aimed at retirement accounts was proposed and modified over time and faced legal challenges; it never became a lasting replacement for securities-law fiduciary duties but increased attention to retirement-account advice standards.
– The “short-lived fiduciary rule” often refers to Department of Labor proposals and regulatory changes that were adopted, challenged, and altered; check current DOL guidance for retirement-advice obligations.

Fast Fact
Under English common law (Keech v. Sandford, 1726), fiduciaries generally cannot profit from their position unless the principal gives informed consent.

Risks of Being a Fiduciary
– Legal liability for breach of fiduciary duty (lawsuits by beneficiaries, shareholders, or regulators).
– Reputation damage and professional discipline.
– Financial exposure to damages and defense costs.
– Potential personal liability for willful misconduct, gross negligence, or self-dealing.

Fiduciary Insurance and Risk Management
– Fiduciary Liability Insurance: covers claims arising from alleged breaches of fiduciary duty (commonly used by corporate directors, plan fiduciaries, trustees).
– Best practices to reduce claims: thorough documentation, written policies, independent valuations for related-party transactions, regular compliance audits, and timely disclosure of conflicts.

How Fiduciary Duties Influence Investment Strategies
– Prioritize capital preservation and appropriate risk-taking aligned with beneficiaries’ needs.
– Avoid high-cost or opaque investments that provide outsized compensation to the fiduciary or their affiliates.
– Place emphasis on diversification and liquidity management to meet foreseeable beneficiary needs.
– Use conservative assumptions for projections and be transparent about tradeoffs (e.g., growth vs. income).

Why Someone Needs a Fiduciary
– Lack of expertise or time to manage complex financial or legal matters.
– Incapacity, minority status, or absence (e.g., decedent’s estate).
– Desire to avoid conflicts of interest or political scrutiny (e.g., politicians using blind trusts).
– Need for impartial oversight for beneficiaries who are vulnerable or inexperienced.

Common Questions Answered
What are the three fiduciary duties owed to shareholders?
– Duty of Care: informed decision-making.
– Duty of Loyalty: prioritize shareholder interests, avoid conflicts.
– Duty to Act in Good Faith: honesty and compliance with governing purpose and law.

Can fiduciary duties require maximizing shareholder returns?
– Not necessarily. Courts generally require directors to act in the corporation’s best interests, which can include long-term value, stakeholder interests, or compliance with law—not a strict mandate to maximize short-term returns.

Tip
If you are appointing a fiduciary (trustee, executor, agent), insist on written terms that define scope, compensation, reporting frequency, and removal procedures. This reduces ambiguity and the potential for future disputes.

More Practical Checklist (For New or Prospective Fiduciaries)
– Confirm your legal authority (court appointment, trust document, corporate resolution).
– Obtain a copy of governing instruments and read them carefully.
– Establish an IPS or policy tailored to the mandate.
– Disclose all conflicts and seek written consent where appropriate.
– Set up accounting, reporting, and document-retention systems.
– Buy fiduciary liability insurance if exposure is material.
– Schedule periodic reviews and audits.

The Bottom Line
Fiduciaries carry a high legal and ethical responsibility to act in the best interests of those they serve. Whether you are a trustee, board member, investment adviser, or guardian, prudence, transparency, and documentation are the foundations of sound fiduciary practice. Proper processes—organizing, formalizing, executing, and monitoring—plus awareness of applicable regulatory regimes help manage risk and fulfill duty to beneficiaries.
