Also Bar, I will add something to your statement if you do not mind.
C2K was not the reason for 1113 it just guaranteed it. With the business model in place putting that added cost in the form of a non-variable over four plus years (life of the contract) resulted in an heavily debt burdened company to plunge faster in to the abyss.
I can equate that to the oil run up last year an a rudimentary level. In effect 147 dollar a barrel oil did not cause the economic collapse, it just helped fuel it.
