7-Eleven¡¯s parent company is considering a massive management buyout that would take it private and end a takeover attempt by Alimentation Couche-Tard.

The effort, which brings together a member of the company¡¯s founding family, a giant trading company and some of Japan¡¯s largest banks, is the latest twist in the battle for control of one of Japan¡¯s most successful enterprises and one of the world¡¯s best-recognized brands.

In a statement released Wednesday, Seven & I Holdings said that it has received a nonbinding offer for the company from Junro Ito, a vice president and representative director of the company, and Ito Kogyo, a company connected to him.
