Um,
As in any decision to buy stock in a particular company, the book value of the company plays a role in the purchase decision.
As long as the book value is such that a complete liquidation of company assets and auctioning off of proprietary property such as customer lists, contracts, and the like, exceeds the purchase price, one should be on firm ground.
Any thoughts of what CHC owns (contracts, customer lists, patents, STC's, etc) that would play a significant part in the buyer's decision to buy CHC? (Assuming they might be intent upon selling off parts of the company)
How would you split up the operating units to maximize the value of their purchase?
