Duplicate Mailings

Shares owned by one person, but held in different forms of the same name (e.g., John Smith, John B. Smith, J.B. Smith), may result in duplicate mailings of shareholder information at added expense to the Company.

Please notify The Bank of New York by calling 800-524-4458 in order to eliminate such duplication.

Multiple shareholders who reside at one address and hold their shares through a bank or broker will receive only one Annual Report and Proxy Statement. This “householding” procedure reduces duplicate mailings and Company expenses. Shareholders who wish to opt out of householding should contact their bank or broker.
