Overissue refers to the issuance of shares of capital stock in excess of the number authorized by a corporation’s charter. Preventing overissue is the function of a corporation's registrar, usually a bank acting as an agent, which works closely with the transfer agent.
A registered security is a financial instrument whose ownership is documented with the issuer or the issuer's agent. This contrasts with bearer securities where physical possession implies ownership.
A registrar is an individual or official body responsible for keeping and maintaining the accurate records of an organization, institution, or legal entity. Their responsibilities vary depending on the field, such as education, real estate, and securities.
