Detroit announced on Thursday a last-minute settlement with its final major holdout creditor, Financial Guaranty Insurance Co., as it edged closer to exiting the biggest-ever municipal bankruptcy. Corinne Ball, an attorney at law firm Jones Day, told U.S. Bankruptcy Court Judge Steven Rhodes that the settlement includes an option for FGIC to develop the Joe Louis Arena and parking garage for a mixed-use project, primarily a hotel serving the nearby Cobo convention center.
