A back of the envelope kind of analysis by Robert Cyran shows that GM may not reach positive net present value even with all its efforts. The rescue package from the governmet required GM to come up with aplan to achieve positive net present value. Treasury wants GM to wipe out two thirds of its unsecured debt by swapping it for equity. Even if this succeeded it would leave GM with $12 billion of unsecured debt and $6 billion in secured debt. With the government money of $13.4 billion the debt goes up to $31.4 billion. GM has to pay $10 billion in cash into the independent fund for UAW members benefits. And net unfinanced health care liabilities for non UAW workers is $8 billion. Prof. Roth at the University of Chicago estimates GM's pension plan may be underfinanced by $23 billion after the market downturn. Cyran uses a conservative number of $10 billion Adding it to the rest gives $60 billion in liabilities. With analyst estimates of $135 billion in sales in 2008 and about 3% margin this implies $4 billion in operating earnings. This seen as a steady ten year income stream would make GM's car business worth $28 billion. These ballpark estimates by Cyran show that GM will have a tough time proving to the government that it can achieve positive net present value and that it should not be drastically reorganized under bankruptcy, which would be redefining the business from the ground up, and discarding old models and behaviours completely by bringing in new managers with no preconceived notions about the business. Actually Cyran's $4 billion in operating earnings based on a 3% margin and $135 billion in sales may be optimistic considering that its based on 2008 performance. 2009 and 2010 performance will likely turn out to be worse than 2008 as both unemployment and consumption spending deteriorate. ...
