Expressing his happiness with the outcome of the investigation, Nilekani said Parekh and Roy have emerged from this stronger.
"They (Parekh and Roy) are people who are thorough professionals. They came here to make a difference, they've already made a difference. The last two years since Salil has been here, the company has changed dramatically for the better," Nilekani said.
