1. What is a proxy?
It is your legal designation of another person to vote the stock you own. That other person is called a proxy. If you designate someone as your proxy in a written document, that document also is called a proxy or a proxy card. We have designated three of our officers as proxies for the 2009 Annual Meeting of Shareowners. These three officers are Gary P. Fayard, Geoffrey J. Kelly and Cynthia P. McCague.
