Tell me please if you know. When the trading company let's say Main Trading LLC has two subsidiaries Sub Main A and Sub Main B. Suppose Sub Main A due to the poor risk management looses all the money. Is it possible that that Sub Main A goes chapter 11 and the Main Trading LLC is not liable for the losses ? What kind of structure is this when under the wing of Main LLC there are affiliates LLC under different names ? I do not understand why subsidiaries of the same company exist under different name? Thank you .
