Rediff, based on a story in Business World says the Ambani feud is close to a solution, brokered by Kamath of ICICI Bank.
I am not entirely certain.
There has been at least one high profile feud in the past - between Bajaj brothers - which was brokered by Auditor Gurumurthy. However the issue is yet to be resolved, after initial acceptance.
Another issue, between Kumarmangalam Birla controlled AV Birla group and L&T was resolved amicably (also brokered by Gurumurthy), primarily because it did not involve blood relations and egos. L&T is a professionally managed company, with no shareholder group controlling it. Kumarmangalam Birla obtained a controlling stake by buying the shares from Dhirubhai Ambani.
The advantages of vertical integration will be lost if Reliance is split along the lines of petrochemicals and oil & gas. In terms of growth though Mukesh will get the better ones oil & gas including the retail portion of the same, as well as the hot infocomm business.
Let us wait and see.
