Rather than cooling off, the liability fires from the 2010 Gulf of Mexico oil spill are heating up and spreading, with a Marin County, Calif., financer providing $50 million to bankroll more legal claims against British petroleum company BP PLC, Bloomberg Businessweek reported. LawFinance Group, a 20-year-old provider of capital for litigation, announced the availability of the $50 million "funding facility" on Nov. 21. LawFinance CEO Alan Zimmerman said the firm closed $9 million in financings during Thanksgiving week alone. "There's so much demand in the Gulf region, I think we'll be going back and raising more money - probably up to $100 million," Zimmerman said. He said the financing would allow plaintiffs' attorneys to keep their small law firms afloat while they joust with BP over disputed claims. The British energy giant already has paid out more than $25 billion for cleanup and damage claims following the April 2010 blowout that killed 11 rig workers and spewed millions of barrels of oil off the coast of Louisiana.
