Murthy, who had shed executive role seven years ago and finally retired as head of Infosys in August 2011, has been appointed Executive Chairman, replacing K V Kamath during whose tenure the company shares slumped 15 per cent.
The current executive co-chairman S Gopalakrishnan will be re-designated executive vice-chairman while S D Shibulal, who was one of the seven engineers to launch the company in 1981 by pooling together USD 250, will continue as Chief Executive Officer (CEO).
Describing his return as "very unusual", Murthy, who will turn 67 in August, said the company was facing challenging times and his job would be to add value to Shibulal's job with ideas.
"The board has taken this step keeping in mind the challenges that the technology industry and the company faces," Kamath said acknowledging calls from shareholders to strengthen executive leadership of the company.
Under Murthy's 19-year tenure as CEO until 2002, Infosys became the first Indian company to list on Nasdaq and grew to become a Rs 23,400 crore (USD 4.1 billion) enterprise.
In FY13, revenues lagged its own forecast and projected lower growth in earnings than industry during the current year.
