Suzlon Energy Ltd., India's biggest convertible bond defaulter, will exit a corporate-debt restructuring program offered by its lenders before March 31 and plans to seek equity investments for its SE Forge Ltd unit, Chairman Tulsi Tanti said in an interview Thursday. Shares of the the Pune-based company, India's second-largest wind turbine maker, climbed the most intraday in about four months, ending four days of losses and paring the year's slump to 18 percent. Suzlon has been working under the nation's debt restructuring rules to repair its finances since it defaulted in 2012. It returned to profit for the full year for the first time since 2009.
