Institutional investment managers who exercise investment discretion over $100 million or more in Section 13(f) securities must report their holdings on Form 13F with the SEC.

In general, an institutional investment manager is: (1) an entity that invests in, or buys and sells, securities for its own account; or (2) a person or an entity that exercises investment discretion over the account of any other person or entity. Institutional investment managers can include investment advisers, banks, insurance companies, broker-dealers, pension funds, and corporations. Section 13(f) securities generally include equity securities that trade on an exchange or are quoted on the Nasdaq National Market, some equity options and warrants, shares of closed-end investment companies, and some convertible debt securities. The shares of open-end investment companies (i.e., mutual funds) are not Section 13(f) securities.

Form 13F requires disclosure of the names of institutional investment managers, the names of the securities they manage and the class of securities, the CUSIP number, the number of shares owned, and the total market value of each security.
