As per the link below, the cost of acquisition of original company (Greenply) after the demerger is 29.7% of the original acquisition cost. Cost of acquisition of new entity (Greenpanel) will be 69.3% of the original acquisition cost.
Is my reading of above link correct? If so, is there a way to modify the acquisition cost of the original company (Greenply) in Zerodha Console to correctly reflect capital gains?
