...Permit companies and intermediaries to satisfy the delivery requirements for proxy statements and information statements with respect to two or more security holders sharing the same address by delivering a single proxy statement or information statement to those security holders. This method of delivery, often referred to as "householding," will reduce the amount of duplicative information that security holders receive and lower printing and mailing costs for companies. These amendments also modify the rules for householding annual reports.
