The Department of Disinvestment is planning to launch this month or early May the 9.33 per cent stake sale in MMTC, which could fetch about Rs 300 crore to the exchequer. The disinvestment department was waiting for the equity markets to stabilise before undertaking the stake sale of MMTC, a source in the finance ministry said. "The base price for stake sale would be in double digits," the official said.
