Board is looking for a suitable successor in his place. Joint President Corporate Controlling Sanjay Khajanchi will serve as Interim CFO, till such time a new CFO is appointed, it added.
Ambuja said the decline in net profit was "on account of lower operating earnings before interest, tax, depreciation and amortisation (EBITDA) and due to an additional depreciation charge of Rs 28 crore on implementation of Schedule II of the Companies Act, 2013."
Its cement sales grew by 3.2 per cent to 4.82 million tonnes (MT) in July-September 2015 from 4.67 MT in the year-ago period.

On outlook it said: "Post monsoon construction activities are likely to pick up."
The long term outlook for cement demand remains positive considering government's focus on housing, concrete roads, smart cities and infrastructure development, it added.
