The buyback scheme - a first in the company's over three decade history commenced on November 30 and closed on December 14.

"(A total of) 11,30,43,478 equity shares were bought back under the Buyback at a price of Rs 1,150 per equity share. The total amount utilised in the Buyback is Rs 13,000 crore excluding transaction costs..." Infosys said in a regulatory filing.

The programme saw participation from Life Insurance Corporation of India, Singapore government, Sudha Gopalakrishnan (wife of co-founder S Gopalakrishnan) and Rohan Murty (son of co-founder NR Narayana Murthy's son) among others.

The filing showed that of all the equity shares tendered in the buyback, 5.41 per cent were by LIC and 2.18 per cent by Singapore government.

Similarly, 15 lakh shares of Sudha Gopalakrishnan and 13.92 lakh shares held by Murty were accepted under the buyback.

As of September this year, Sudha Gopalakrishnan held the largest share in individual capacity among promoters group members with 2.14 per cent shareholding.

The founders and families classified as promoters group held 29.28 crore shares, or 12.75 per cent, in Infosys at the end of September 2017.

After the buyback, the promoter group now holds 12.90 per cent share, as per the filing.

The buyback had been a long-standing demand by some of the founders and high-profile former executives, who have been pushing Infosys to return surplus capital to shareholders.

Share buybacks typically improve earnings per share and return surplus cash to shareholders, while supporting share price during period of sluggish market condition.

Earlier this year, its larger rival Tata Consultancy Services completed a Rs 16,000-crore mega buyback offer. Other competitors like Cognizant, Wipro and Mindtree had also made similar announcements.
