Calculation of Loss for GM Bonds and Cost Basis of New Issues
I will say in advance this is not a great answer, but I had a similar experience when I owned a CIT bond that defaulted. I ended up getting stock plus 5 newly issued bonds as a replacement for my defaulted bond. My broker had no clue on cost basis and didn't even try for the new securities, I called the "hotline" setup about CIT default and they knew nothing, and finally I read all the paperwork around the restructuring but it was less than transparent. So in the end I ended up claiming everything as a wash, no gain/no loss - which probably screwed me in the end as I believe I ended up down. It was a very small position for me and was not worth the headache :(
