Infosys co-founder Nandan Nilekani

Returning to his home turf, Infosys after eight long years to take over as non-executive chairman, Nandan Nilekani attended an investor call -- his first task -- on Friday morning.

"I like to believe that I am here as more than just a founder. After resigning from Infosys eight years back, I have done fairly significant work. I was invited to the board by all parties and I assume people see me as a unifying and holistic person and I believe I am. This is about consensus building," Nilekani said.

Soon after Nilekani took charge on Friday morning, a rejig in the company board started with co-chairman R Seshasayee and former CEO Vishal Sikka stepping down from the Infosys board along with independent board members Jeffrey Lehman and John Etchemendy. Another co-founder Ravi Venkatesan also stepped down from the company board but will continue as an independent director.

Here are the some of the key highlights from Nandan Nilekani's investor call:
