These institutions are multi million, some billion industries. Whilst they want to protect their interests they also want to protect their reputation which is worth far more than the few million they pumped into LGB. You might be right Sommet that at the outset they signed the SOA for that reason, although it is a moot point that hasn't been proven in law.
Whatever happens with LGB now, if DB feels that he has no option but to file for liquidation under the terms of the SOA, as a result of the writ then you can g'tee one thing that the institutions would right off their investment rather than join the RA who maybe the only horse in town then. For them, image in the city, the press etc is more important than the few million they would have to write off against tax.
