As Vijay Mallya and his son Siddharth sit with a Rs 21 crore purse and seven cricketers he can sell to make some money in the IPL auction, India's public sector banks are struggling to recover even a fraction of their Rs 7000-crore loans from Mallya's grounded Kingfisher Airlines. As Vijay Mallya and his son Siddharth sit with a Rs 21 crore purse and seven cricketers he can sell to make some money in the IPL auction, India's public sector banks are struggling to recover even a fraction of their Rs 7000-crore loans from Mallya's grounded Kingfisher Airlines. Documents, forensic reports and accounts of people from across the world studied by dna reveal that members of the 17-bank consortium of lenders led by SBI may never be able to recover the money loaned to Mallya's airline. The State Bank of India(SBI), the major lender to Mallya's airline, till now has managed to recover only Rs 155 crore out of the Rs 1,623 crore due from it. dna has learnt from official SBI sources that the value of Kingfisher Airlines pledged to the bank has now plummeted from Rs 4,000 crore to Rs 6 crore! SBI is unable to find a single buyer for the 'Kingfisher' trademarks. And Kingfisher Airlines has told Indian courts that it is not in a position to payback its debts. According to the hypothecation deed signed between SBI and Kingfisher Airlines on August 10, 2010, SBI was given ownership of all trademarks and goodwill if Kingfisher Airlines failed to repay its debts. These included Fly Kingfisher (label mark & word), Flying Models, Fly The Good Times, Funliner & Kingfisher (label mark). In 2009, global consultancy firm Grant & Thronton valued Kingfisher trademarks at Rs 4,111 crore or roughly $1 billion. In 2012, when the airline's licence was suspended by India's aviation regulator Director General of Civil Aviation (DGCA), Kingfisher Airlines valued itself at Rs 3,008 crore. The current value of the trademarks now stands at a mere Rs 6 crore! "We have put it up for sale. But have not received any satisfactory responses till now," according to official bank sources. Year Brand value of Kingfisher Airlines Money owed to banks (estimated) 2009: Rs 4,111 crore : Rs 4,000 crore 2012: Rs 3,008 crore : Rs 7,000 crore 2014: Rs 6 crore : Rs 7,000 crore The role of some banks is also quite suspicious. One of the banks under the radar of the CBIfor its loans to Kingfisher Airlines is IDBI. CBI sources reveal that IDBI had extended loans to Kingfisher despite being warned by some board members not to do so. The result is that the bank has ended up with bad debts of Rs 700 crore. Curiously, IDBI gave the loan to Kingfisher after being pledged the airline's now 'junk' trademarks worth a mere Rs 6 crore! Among the medium-sized banks, Bank of India is owed Rs 308 crore. The bank was mortgaged all the current assets of the airline. It included items like air conditioners, tractors and monetarily unsubstantial items like folding chairs. The bank has been struggling to recover even a fraction of its loan from the sale of Kingfisher's bag of random goodies. How could a bank give over Rs 300 crore after being pledged office stationary like boarding pass printers & folding chairs remains a mystery. BOI did not respond to dna's questions. Sumanto Bhattacharya, spokesperson of UB Group, denies manipulating the banks, "There is no question of any deliberate undervaluation by Kingfisher Airlines Ltd as the banks themselves had conducted their own due diligence including the security available and also satisfied themselves about the viability of Kingfisher Airlines Ltd before undertaking the debt restructuring." Documents accessed by dna show that Mallya had also given a personal guarantee of several other physical properties â€“ one of which was his 'Hollywood' style Kingfisher Villa located at Candolim, Goa. SBI is awaiting a reply from the District Magistrate who has to give permission for police personnel to step in and help the bank recover the property. The application is yet to be even listed for hearing. Even if SBI gets physical possession of the property, all it will manage is to dent Mallya's ego. The value of the villa, though higher than Kingfisher trademarks, is barely a fraction of the Rs 1,600 crore that Mallya owes SBI.
