Yes. It depends on where/when you bought. Your 20 bonds sounds like you may be PRE-BK??? There were other bonds, that got more, if I remember, but they were not of the actual holding company.
Over all, if my memory serves me, seniors of holding got about 10% to 12% face plus 2 sets of warrants. I had 2 different types of securities, but sold before the end.
I got in way low (I was post BK), so it was a profit for me.
imo
