SAO PAULO (Reuters) -Creditors of Brazilian retailer Americanas approved a restructuring plan on Tuesday, which features a $2.5 billion capital injection by main shareholders and a divestment agenda aimed to cut its around 50 billion reais ($10.28 billion) debt. Americanas, a nearly century-old company backed by the trio of billionaires who founded 3G Capital, filed for bankruptcy earlier this year after uncovering $4 billion of accounting inconsistencies. The approval marks a key step for Americanas, but it still needs to be ratified by a Brazilian judge.
