Google and Amazon are in talks with the Tata Group to buy the data centre business of the company. It is expected that the deal would be worth between Rs 42.61 billion and Rs 45.89 billion.

Apart from Google and Amazon, Blackstone Group, Carlyle, KKR, Bain Capital, Advent International and SembCorp Industries are also in talks with the Tata Group. The companies are looking to buy up to 74 per cent stake in the data centre unit and take control of the business that is spread across 44 locations in India and abroad.

The transaction, if successful, will help Tata Communications reduce the debt burden and concentrate on its core data carrier business. According to a July 2015 investor presentation, the company has a net debt of Rs 91.78 billion.
