HOUSEHOLDING OF DISCLOSURE DOCUMENTS
The SEC has approved a rule allowing us to send a single proxy statement to any household at which two or more stockholders reside if we believe the stockholders are members of the same family. This rule benefits both you and us by reducing the volume of duplicate information received at your household and helping to reduce our expenses. The rule applies to our annual reports, proxy statements and information statements. Each stockholder will continue to receive a separate proxy card or voting instruction card.
If your household received a single proxy statement, but you would prefer to receive your own copy, please contact our transfer agent, Mellon Investor Services L.L.C., by calling their toll-free number, (800) 635-9270. If you would like to receive your own set of our disclosure documents in future years, follow
the instructions described below. Similarly, if you share an address with another stockholder and together both of you would like to receive only a single set of our disclosure documents, follow these instructions:
