Three hedge funds that own defaulted Venezuelan bonds hired a Washington law firm to explore legal options for repayment. The group owns more than 15 percent of the $1.5 billion outstanding of Venezuela’s 2034 bonds, according to Mark Stancil, the attorney at Robbins, Russell, Englert, Orseck, Untereiner & Sauber LLP who’s representing the investors. Stancil declined to name the companies. He helped represent hedge funds Aurelius Capital Management and Davidson Kempner Capital Management in their lawsuit against Argentina.
