Cost of acquisition price for Aditya Birla Capital (ABCL)

I have received Aditya Birla Capital shares due to demerger of Grasim in the ration of 7 for 5. Now for the purpose of capital gains what is the cost of acquisition ratio of the demerger for ABCL . I have not been able to find any ratio on the web…Without this I would not be able to calculate the P&L Thanks

You need to Divide the Total Cost of Old Shares / Sum of Total Value of Both the Shares * Price of Shares on Demerger Individually to apportion the cost between both the companies.

I think the cost of acquisition after demerger is calculated on the basis of the ratio of division of networth of the original company between the demerged companies . Read here for reference. Grasim must’ve shared this ratio.

Thanks…Grasim has not informed or responded to me .
