    FINRA Rule 4512(c): what counts as an institutional account

    FINRA Rule 4512 sets the information a member firm must keep for each customer account. Paragraph (c) defines an "institutional account" — an account of a bank, savings and loan, insurance company, registered investment company, an investment adviser registered with the SEC or a state, or any other person with total assets of at least $50 million. Institutional accounts are exempt from some of the rule's requirements, such as asking for a trusted contact person.

    Common questions

    What is an institutional account under FINRA Rule 4512(c)?

    An account of a bank, savings and loan, insurance company, registered investment company, an SEC- or state-registered investment adviser, or any other person with total assets of at least $50 million.

    Do institutional accounts need a trusted contact person?

    No. The trusted contact request in Rule 4512(a)(1)(F) applies to non-institutional customer accounts.

    Is Rule 4512(c) the same as the institutional investor definition in Rule 2210?

    No. They are similar but not the same. Check the definition in each rule before you rely on it.
