A Rolling Close refers to an early disbursement of funds during a company's round and is requested by the company.
A Rolling Close close allows an issuer to receive funds before their official offering deadline. In conjunction with the rolling close, investors will be notified of this close and have a chance to withdraw before the closing. This means that shares will be issued to investors earlier than the deadline.
If an issuer intends on conducting rolling closes, this information and the terms will be disclosed in their offering statement.
