Additional Information

“Householding”—Stockholders Sharing the Same Last Name and Address

The SEC has adopted rules that permit companies and intermediaries (such as brokers) to implement a delivery procedure called “householding.” Under this procedure, multiple stockholders who reside at the same address may receive a single copy of our Annual Report and proxy materials, including the Notice of Internet Availability, unless the affected stockholder has provided contrary instructions. This procedure reduces printing costs and postage fees and helps protect the environment as well.

This year, a number of brokers with account holders who are our stockholders will be “householding” our Annual Report and proxy materials, including the Notice of Internet Availability. A single Notice of Internet Availability and, if applicable, a single set of Annual Report and other proxy materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. Stockholders may revoke their consent at any time by calling Broadridge at (866) 540-7095 or writing to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York, 11717.

Upon written or oral request, we will promptly deliver a separate copy of the Notice of Internet Availability and, if applicable, our Annual Report and other proxy materials to any stockholder at a shared address to which a single copy of any of those documents was delivered. To receive a separate copy of the Notice of Internet Availability and, if applicable, Annual Report and other proxy materials, you may write our Secretary at 420 Taylor Street, San Francisco, California 94102, Attn: Secretary, telephone number (415) 344-0333.

Any stockholders who share the same address and receive multiple copies of our Notice of Internet Availability or Annual Report and other proxy materials who wish to receive only one copy in the future can contact their bank, broker or other holder of record to request information about householding or our Secretary at the address or telephone number listed above.
