Oklahoma Form U-1 is a uniform application to register securities in the state of Oklahoma. It is used by any person or entity who wishes to register securities such as stocks, bonds, or other investments. The form requires information including the type of security, the issuer, the number of shares or other units, the offering price, and the type of offering. It also requires the signatures of all parties involved in the offering, including the issuer, an authorized representative, and the underwriter. There are two types of Oklahoma Form U-1: the Short Form U-1 and the Long Form U-1. The Short Form U-1 is for smaller issues of securities such as private placements, while the Long Form U-1 is for larger issues, such as public offerings. Both forms must be filed with the Oklahoma Department of Securities.
