Sounds like it. Take into account the impending fine, all the lawsuits in many countries, the family control of the firm... Takata at this point could well be worth nothing at all.
They have other product lines (the article mentions their seat belt business), but my guess would be that the airbag liabilities would vastly exceed the income & valuation of those.
Yeah, the uncertainties about their future must weigh heavily on their value. If they fail to meet commitments set by the US they're liable for another 130mm in fines. That doesn't address the possibility of future lawsuits either.
Does this mean they have $520m in cash, but the stock valve is less than their bank account?
