RSA Group, in February, announced its plans to exit Royal Sundaram Alliance by offloading its 26 per cent stake to Sundaram Finance for Rs 450 crore.
Post stake sale, Royal Sundaram has become a 100 per cent subsidiary of Sundaram Finance and its associates.
Royal Sundaram Alliance was the first private general insurance company, which was granted licence in 2000, following opening up of the sector.
It offers motor, health, personal accident, home and travel insurance, among others.
Last month, Competition Commission of India (CCI) had approved the deal.
