Brazil might be the target of industrial espionage—thanks to the reported activities of the National Security Agency—but the South American nation is also attracting the interest of Am Law 100 firms drawn to the crumbling empire of Brazilian billionaire Eike Batista.

Bloomberg reported last week that Batista, once a symbol of Brazil’s growing economic prowess, had retained Quinn Emanuel Urquhart & Sullivan to represent him after his oil company OGX Petroleo e Gas Participacoes defaulted earlier this month on a $44.5 million interest payment, triggering a 30-day period to negotiate with bondholders.
