Information technology major Tata Consultancy Services' much-awaited initial public offer to mop up an estimated over Rs 5,000 crore (Rs 50 billion) is likely to hit the market on July 29 subject to all approvals from the Securities and Exchange Board of India.

The company was presented with two plans for opening the issue -- first beginning on July 23 and the second by the end of the month -- from the merchant bankers appointed for the IPO, the biggest in the private corporate sector, sources associated with the process said.

When contacted, Atul Takle, vice president, corporate communication, TCS, told PTI from Mumbai: "We have not yet received all Sebi approvals."

"Any date is speculative," he said when asked if the company could launch its IPO on July 29.

Spokesperson of Tata Sons, the holding company of the Tata Group, said, "No decision has been taken yet."

Sources, however, said it would require about ten days to launch the IPO after all the formalities, including filing with the Registrar of Companies, are completed.

Following the filing of draft red-herring prospectus by the company, Sebi had sought some clarifications from it in the first week of July.

Incidentally, July 29 coincides with the birthday of the group founder JRD Tata and the centenary celebrations of the group.

Meanwhile, Tatas today submitted response to all the clarifications sought by Sebi with regard to the draft red herring prospectus for the IPO of TCS.

Sebi had issued "certain observations" and "sought clarifications" on draft prospectus for TCS Ltd's initial public offering in the first week of July.

Tackle said: "We have given response to all the clarifications sought by Sebi".

The draft prospectus was filed on June 10 with Sebi.

Sebi in a statement had said on July 5 that it has issued observations on the book-built issue of TCS, lead managed by JM Morgan Stanley, DSP Merill Lynch and JP Morgan India Pvt Ltd.

After all the formalities are completed, TCS would be required to announce the price band and the company officials would undertake a global roadshow for the issue.

Tata Consultancy Services Ltd will offer 5.54 crore (55.4 million) equity shares of Re 1 each, including a fresh issue of 2.27 crore (22.7 million) shares, in its IPO through the book-building route.

The issue also comprises offer for sale of 3.26 crore (32.6 million) shares by Tata Sons Ltd and other shareholders of TCS, and a further greenshoe option by Tata Sons for 831,000 shares each.
