The South Indian Bank (SIB) does not consider Megastar Mammootty as an ageing brand ambassador. SIB managing director and chief executive officer V.A. Joseph said Tuesday that the bank is more than 81 years old and hence for it Mammootty is quite young. We are the only bank in South India which has a brand ambassador. Through Mammootty we have received a huge boost. Every time I go to Middle East, there are numerous requests at our customer meetings, to bring Mammootty for one such meeting, said Joseph. On Tuesday, the SIB inked an agreement with Hatton National Bank (HNB), the largest private sector bank in Sri Lanka, for exchange of expertise and services. Rajendra Theagarajah, managing director of HNB who signed the MoU, said Mammootty is popular in Sri Lanka too. We are fortunate to have a new tie-up with the SIB, whose brand ambassador is none other than Mammootty, he said. Mammootty said, The initial contract with the SIB was for three years. It has now been extended for another five years.
