Aux Sable Revenue and Competitors

Aux Sable's vision is to be a market leader in the natural gas processing and NGL industry within selected regions of North America where Aux Sable can secure and expand competitive advantages to achieve predictable earnings growth. Aux Sable was established as part of the development of the Alliance Pipeline system that was constructed over 1998-2000 with start-up on December 1, 2000. Two companies were established, one in the U.S. (Aux Sable Liquid Products or "ASLP" located in Channahon, Illinois) and one in Canada (Aux Sable Canada or "ASC" located in Calgary, Alberta) to manage the natural gas liquids (NGLs) business associated with the Alliance Pipeline. Aux Sable has the exclusive right to extract NGLs from Alliance Pipeline gas. Alliance Shippers are kept whole on an energy basis as Aux Sable is required to provide any make-up energy to balance for NGLs it has extracted from Alliance gas.
