Chapter 11 is a get out of jail card for big business. WMI took advantage of it like thousands of others.
Shed those cement shoes, and reorganize around remaining assets. Dump retirement plans, dump enough shareholders, dump debts......
Chapter 11 only require that you claim enough assets to cancel liabilities. You don't have to reveal all the other assets you might own, as they aren't required to settle the liabilities stated.
Chapter 11 is a lather, rinse, repeat scam. I'll never be a common stockholder of most large companies ever again.
