When a customer holds securities in street name, who is responsible for forwarding proxy materials to the beneficial owner?

Why B — The broker-dealer holding the securities

When securities are held in street name (registered in the name of the broker-dealer), the broker-dealer is responsible for forwarding proxy materials and other corporate communications to the beneficial owners (customers). The broker-dealer must make every effort to forward these materials in a timely manner so that customers can exercise their voting rights. Under NYSE and FINRA rules, broker-dealers must also inquire whether customers wish to receive proxy materials and must vote shares only as directed by the beneficial owner on non-routine matters.
