"This incident is a black-eye because we have been promoting Indian entrepreneurs, Indian corporate as the flagship of brand India and when one of the lot really has a deplorable behaviour then obviously its not a good thing.

"It's something that is a setback to what we have been trying to accomplish," Nilekani told in an interview to a private television channel.

Talking about the fallout of the incident, Nilekani said, "Investors who have been shocked by this episode will obviously look for company numbers. We believe that the more data you share with the investors the better it is."

"All of us who run companies must really put ethics, corporate governance and running a transparent company in the front. If results are bad we should declare that, if profits are low we should declare that but we should not do anything which impairs the trust of our stakeholders," he added.
