Well, reportedly the total write-downs to be announced tomorrow may be in excess of $5 billion CAD, equivalent to the entire value of the CSeries investment to date, and almost 20% of Bombardier's total assets.
That practically guarantees the CSeries will be a multi-billion dollar loss to Bombardier, regardless of what happens going forward.
And they're not "out of the woods" yet, even with investments from Quebec.
It will be difficult for Bombardier's founding family to retain control, after all of this mess.
