The Burman Family Office is the private investment arm of the family that controls consumer goods company Dabur India Ltd. After the investment, Hero-Burman will together own just under 20 per cent of Fortis, including the 3 per cent they already own, Mr Munjal said at a televised news conference on Friday. The overnight decision saw Fortis shares gain in premarket trading, only to fall as much as 4.9 per cent in afternoon trade. "We believe the reasons for considering this offer could be no requirement of due diligence and lesser equity dilution as compared to other offers," ICICI Securities analyst Sriraam Rathi said in a research note. "Munjals/Burmans have built successful businesses in non-healthcare fields and are passionate about the Indian healthcare industry," he said, expecting the offer to receive shareholder approval.
