Investment Advisers Act of 1940: Definition, Overview, and Key Responsibilities

A comprehensive guide to the Investment Advisers Act of 1940, detailing the role, responsibilities, and legal requirements for investment advisers in the United States.

The Investment Advisers Act of 1940 is a U.S. federal law that defines the role and responsibilities of an investment adviser. Enacted to regulate the practices and conduct of financial advisers, this legislation forms one of the cornerstones of U.S. securities law.

Definition of an Investment Adviser

Under the Act, an investment adviser is anyone who:

  1. Provides advice or analyses regarding securities,
  2. Engages in the business of advising others, either directly or through publications,
  3. Receives compensation for such services.

Registration Requirements

One of the primary requirements of the Act is that investment advisers must register with the Securities and Exchange Commission (SEC). This involves submitting a Form ADV that discloses:

  • Educational background
  • Business practices
  • Disciplinary history

Fiduciary Duty

Advisers must act in the best interests of their clients, a principle known as fiduciary duty. This includes:

  • Providing unbiased advice
  • Avoiding conflicts of interest
  • Disclosing all material facts

Types of Investment Advisers

  • Registered Investment Advisers (RIAs): Must register with the SEC and adhere to strict regulations.
  • Exempt Reporting Advisers (ERAs): Exempt from registration requirements but must still file reports with the SEC.
  • State-Registered Advisers: Advisers managing smaller amounts of assets, usually under $100 million, must register with state regulators instead of the SEC.

Considerations

Compliance with the Act requires thorough documentation and operational transparency. Advisers must:

  • Keep accurate records
  • Submit regular reports to the SEC
  • Undergo periodic audits

Applicability

The Act applies universally to anyone in the U.S. offering investment advice, with specific exemptions for certain professionals, including lawyers, accountants, and brokers if their advisory services are incidental to their main profession.
