Massachusetts U-5 is the term used to refer to the uniform securities' registration form for Massachusetts. It is the form used by securities dealers and broker-dealers to register their securities with the Massachusetts Securities Division. The form is used to register securities offered in the state of Massachusetts, and must be completed and filed with the division prior to offering any securities in the state. There are two types of Massachusetts U-5 forms: the Uniform Application for Broker-Dealer Registration (Form U-5A) and the Uniform Application for Investment Adviser Registration (Form U-5B). Both forms require detailed information about the firm, its activities and the securities it intends to offer.
