It depends on the subsidiary and how the bulkheads are constructed. I believe a subsidiary of BHE, like Pacificorp for instance, can be put into bankruptcy without the other assets of BHE being risked, much less the parent company holding company. But I'm sure there are exceptions for nefarious asset stripping or fraud. I mean, look at JNJ and the Talc stuff - you don't see all of JNJ at risk.
