Dangagan,
Oh ye of little faith!!!
ACN operated very well for years before CHC came into the picture, and I dare say will continue to operate very well long after CHC has left the building.
Don't get me wrong here, I do not mean to imply that CHC is the end of all ACN's problems, quite the contrary.
Remember that before CHC there was Schreiner to keep the ship pointing forward and if CHC does indeed leave the building, who will step up to the plate then?
