Detroit's state-appointed emergency manager expects to file a roadmap in federal court on Friday detailing how the city will treat some $18 billion of debt and other obligations as it tries to exit bankruptcy, Reuters reported yesterday. "Friday is the present expected day to file," said Bill Nowling, a spokesman for Kevyn Orr, the city's emergency manager. Bankruptcy Judge Steven Rhodes, who is overseeing Detroit's bankruptcy case — the largest municipal bankruptcy in U.S. history — set a March 1 deadline for the plan. The city sent a proposed plan to adjust its debts to creditors on Jan. 29. The city said that the proposed plan reflected discussions with creditors and said it could be modified before being presented in court.
