Narayana Murthy speaks exclusively to NDTV

Dr. Roy: Thank you very much everyone, thank you Mr. Murthy. I would say that Infosys is for me & for may people in India more than just a multi billion dollar company. For many of the younger generation and many of the young people here about half my age actually it symbolizes hope; it symbolizes confidence; it symbolizes what new India is capable of doing. Taking on the world and beating the world in its own game - and they have done it by themselves. They weren’t handed down any money, they weren’t handed down any assets. and I would say Mr. Murthy you may not agree because you are a modest person. I think in my view Infosys has done single handedly more to change the mood of this country than any other institution I can think of post independence. And the one man who symbolizes Infosys, its hope, its confidence, its values, its ethics and its high PE ratio! Mr. Narayana Murthy.

Mr. Murthy: Thank you. Thanks Prannoy for those very kind words. You’ve always been very kind to me.
