Why did I receive a one page notice in the mail regarding the Internet availability of proxy materials instead of a full set of printed proxy materials?
Pursuant to the notice and access rules adopted by the SEC, we have elected to provide shareholders access to our proxy materials over the Internet. Accordingly, on or about November 4, 2009, we are sending a Notice of Internet Availability of Proxy Materials a (Notice) to all of our shareholders as of the record date. The Notice includes instructions on how to access our proxy materials over the Internet, how to vote and how to request a printed copy of these materials. Proxy materials will be made available on the Internet on or about November 4, 2009.
