By Soyoung Kim NEW YORK (Reuters) – Comcast Corp’s proposed $45.2 billion merger with Time Warner Cable Inc would generate as much as $143 million in investment banking fees, providing a rare boon to Wall Street banks grappling with a dearth of large corporate takeovers. JPMorgan Chase & Co, former top Morgan Stanley banker Paul Taubman and Barclays, which together advised Comcast, would split an estimated $51 million to $68 million in advisory fees if the proposed deal goes through, according to estimates by Freeman & Co LLC. Financial advisers to Time Warner Cable – Morgan Stanley, Allen & Company, Citigroup Inc and Centerview Partners – are set to share $57 million to $75 million in fees, the estimates show.
