Allows a financial institution that participates in the signature guarantee program to validate a medallion stamp signature

HB 3336 requires financial institutions participating in the signature guarantee program (such as banks, credit unions, and brokerage firms) to validate medallion stamp signatures used when transferring securities like stocks or bonds. This validation confirms the identity and legal authority of the person signing transfer documents, ensuring the signature is legitimate. Transfer agents and security issuers that rely on these validated signatures are protected from liability for losses resulting from their reliance. The bill aligns state requirements with federal standards for the signature guarantee program, ensuring consistent and secure security transfers.
