TOKYO (Reuters) - The founding Ito family behind Japanese retailer Seven & i ( SVNDF ) aims to raise more than 8 trillion yen ($52 billion) to take it private by the end of this financial year, Japanese public broadcaster NHK reported on Tuesday.  

The family has established a special purpose company that is in talks with Japan's three largest lenders and major U.S. financial institutions to raise funds to take the 7-Eleven owner private.

A spokesperson for Seven & i ( SVNDF ) could not be reached for comment outside normal business hours in Tokyo.

Seven & i ( SVNDF ) has been under pressure to convince investors it can enhance value on its own and fend off a $47-billion takeover bid from Canada's Alimentation Couche-Tard ( ANCTF ).

It said last week it had received a buyout proposal from the founding Ito family.

Going private would allow it to continue under current management and remove pressure from shareholders to sell off more of its assets - as well as eliminate the threat from a bidder that it may see as hostile. A management buyout offer could also be a tactic to force Couche-Tard to bid more.

The company's shares ended little changed on Tuesday, but have climbed by more than 50% to record highs since August as takeover speculation swirled.
