What is “Medallion Signature Guarantee?
Written confirmation by a financial institution such as a bank or brokerage firm that a customer’s signature is valid and pertinent documents have been presented and deemed to be authentic. Financial institutions belong to one of three Medallion Signature Programs. For your protection, TranShare requires a Medallion Signature Guarantee on negotiable documents such as a stock power to ensure that those endorsing negotiable documents are, in fact, the registered owners whose names appear on the face of the certificate.
