The Company will provide an update on its proposed financing plans related to the recently announced combination of AT&T Broadband with Comcast. In connection with this update, management will discuss the proposed legal and organizational structure for the combined company's balance sheet. In Cable, Comcast will provide examples of its successful integration of cable systems acquired over the past twelve months.
