A consortium led by Tokyo-based fund Japan Industrial Partners Inc., the preferred bidder for a potential buyout of Toshiba Corp., is unlikely to secure a bank loan needed to finance the takeover by the Nov. 7 deadline, sources familiar with the matter said Wednesday.

A group of banks, including Mitsui Sumitomo Banking Corp., have been in discussions with JIP on a loan of over 1 trillion yen ($6.8 billion) sought by the consortium as part of its Toshiba turnaround plan, but the banks did not give the nod due to the risks involved in the deal, the sources said.
