The Tata Power Company is planning to raise up to Rs 40 billion by selling corporate bonds with the aim of funding its proposed acquisition of renewable energy assets from the Welspun Group. Tata Power has reached out to some top fund houses and investment bankers in an attempt to assess investor appetite. The proposed bonds may offer a 9-9.25 per cent. The company is now considering different maturity options that suit investors best – it could be be a 10-year maturity with a one-year put-and-call option, which allows both investors and issuers to surrender or withdraw from the issue after the stipulated period but well before the scheduled maturity. The bonds could also be of multiple maturities ranging from one to four years.
