Jefferson County, Ala., leaders expect to file a bankruptcy exit plan to the court in early June that will show how much it intends to pay back bondholders who extended $3.6 billion to fix its leaky sewer system, a county official said, Dow Jones Daily Bankruptcy Review reported today. Jefferson County Commission President David Carrington said he does not know whether the 658,000-resident county's proposal will have support from bondholders, who have the power to vote to reject the plan.
