The "Informed Investor Access Act" proposes to significantly broaden the definition of an accredited investor within the Securities Act of 1933. This legislation aims to allow more individuals to qualify for certain investment opportunities by recognizing their access to professional financial guidance. Specifically, the bill amends the definition to include any natural person who an issuer reasonably believes is receiving personalized investment advice or recommendations for a transaction. This advice must come from either an investment adviser registered with the Securities and Exchange Commission (SEC) or a supervised person thereof, or a broker or dealer registered with the SEC or an associated person acting on their behalf. The bill also mandates that the SEC revise its regulations to conform to this expanded definition, ensuring consistent application across all relevant rules.
