BANGALORE/MUMBAI: Arun Jain-spearheaded Polaris Financial Technology's move to divest the IT services unit FT Sourcing — valued at $300-350 million — has attracted bids from four bigger rivals, including Wipro, HCL Technologies and L&T Infotech, said banking sources familiar with the process. Axis Capital is running a process exploring a sale, with long-time financial investor Citigroup seeking an exit. The Wall Street bellwether Citigroup is also the top client for the IT services business, which has an estimated $340 million revenue. Bankers cited earlier in the report said the four bids filed before last week's deadline came mostly from Citigroup's large technology vendors, as the banking giant looks to consolidate its outsourced business. Tech Mahindra is possibly the fourth bidder in the fray besides Wipro, HCL and L&T, they added.
