The certification was attached. Chairman Atkinson directed the Numbering Oversight Working Group (NOWG) to consider this notification on behalf of the NANC the same day. The NOWG was tasked with providing feedback to the NANC during the March, 2006 NANC meeting of any issues or concerns regarding the contents of this notification. The NOWG has discussed this notice and has no known issues or concerns regarding the neutrality of the shareholder change.
