I have been a shareholder of Tata Steel since 1984-85 as I received shares on conversion of 13.5 % Convertible Bonds.
Kindly advise what should be considered as cost of acquisition of these shares as I could not find any old records about face value of the bonds, conversion ratio, conversion price etc.
Inquiries with RTA has drawn a blank as the matter pertains to the era of physical holdings and nobody seems to have any clue. Google search did not help.
