If this deal sees light of the day, TCS will become more than twice the size of Infosys!

Tata Consultancy Services has taken a U-turn and is yet again in talks with Dell to buy its Perot IT business.

Earlier, the deal could not see light of the day over price issues. But now TCS is not alone as US-based Cognizant and France-based Atos SE are also in the fray to buy Perot.

Reportedly, after the talks ended between TCS and Dell, the latter took up the matter again but the pricing is still a concern.

"They (TCS and Perot) are several hundred million dollars apart and there are questions about which contracts will be transferred. This is far from done," one the people with direct knowledge of the talks told ET.

Dell had bought Perot for $3.9 billion in 2009 but did not give much to the company as it failed due to underbid contracts.

ET reported that TCS had bid little less than $4 billion during its initial talks, Cognizant and Atos came up with $4.2 billion and $4.3 billion, respectively.
