Bankruptcy being expensive, personally I think any company going into bankruptcy is expensive. Anytime when a company's debt hits over $10 million then is it expensive. And sometimes your not even 100% sure if that company will even survive. When companies owe money they can either do it voluntary or the people they owe can file bankruptcy. In the article Corporate Bankruptcy: Costly and often worthless is detailing all the major corporate companies and how expensive the debt was.
In this article It uses the Lehman Brothers bankruptcy and how expensive it was. The Lehman Brothers debt total was around $2 billion and unfortunately they still went bankrupt. But there are always companies that come away debt-free, like UAL and Pacifice Gas & Electric's. UAL was in a three year bankruptcy slog, their bankruptcy total was at $330 million. All in total now we know that even the greatest companies sometimes aren't "the greatest companies."
