LIC stake buy will help the debt-ridden state-owned bank get a capital support of Rs 100-130 billion.
LIC has been looking to enter the banking space by acquiring a majority stake in IDBI Bank as the deal is expected to provide business synergies despite the lender's stressed balance sheet.
It will get about 2,000 branches through which it can sell its products, while the bank would get massive funds of LIC.
The bank would also get accounts of about 22 crore policyholders and subsequent flow of fund.
Once the deal goes through, IDBI Bank, which is grappling with mounting toxic loans with gross non-performing assets rising to a staggering Rs 556 billion at the end of the March quarter, will get much-needed capital support to revive its fortune.
