A New York Amendment to Prospectus is a legal document that must be filed with the New York State Attorney General’s Office when an issuer of securities wishes to amend the original prospectus. This amendment must include all material changes to the original prospectus and must be filed prior to the sale of the securities in the state of New York. Generally, the amendment must include any changes to the offering price, terms of the offering, or any other material changes to the original prospectus. There are two types of New York Amendment to Prospectus which include the Form U-1 and the Form U-2. Both forms must be filed with the New York State Attorney General's Office in order to be accepted. The Form U-1 requires the issuer to provide a copy of the amended prospectus to the attorney general and the Form U-2 requires the issuer to provide a copy of the original prospectus and the amendment to the attorney general.
