I do not know how history will judge me, but let me say that I've spent a lot of time and energy trying to transform the Tatas from a patriarchal concern to an institutional enterprise. It would, therefore, be a mark of failure on my part if it were perceived that Ratan Tata epitomises the Group's success. What I have done is establish growth mechanisms, play down individuals and play up the team that has made the companies what they are. I, for one, am not the kind who loves dwelling on the 'I'. If history remembers me at all, I hope it will be for this transformation.

Companies the size of PepsiCo is like running a little republic, there is no question about it. The only difference is that I don't have to worry about the media hounding me every day, on every word that I say. I have a board of directors that runs the country in the interest of the stake holders.
