• To mail a security certificate- If you are sending an actual security certificate, please write a letter to ERD giving us permission to transfer the ownership of certificates. Either you or your broker may write this letter. Before mailing the actual certificate(s), be sure to sign each one exactly how your name appears on the document. Make sure to have a Signature Guarantee to endorse the transfer by asking your bank to stamp a medallion signature certification ensuring the authenticity of your signature. Next, mail the certificate(s) to ERD. The certificate must be accompanied by a stock power letter (one for each certificate) giving ERD ownership of the certificate. Please mail a copy of the original letter which gives ERD permission to transfer the certificate, along with the certificate and stock power letter. Mail your certificate, stock power letter and original letter to the address below to the attention of Teresa Franco, Donor Associate.
