The auction for bankrupt electronic retailer RadioShack’s name and customer data will resume on Tuesday with bidding at $15 million, according to a lawyer tracking the sale. The high bidder is an affiliate of the Standard General hedge fund, which acquired 1,740 RadioShack stores in April, according to Adrienne Walker of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo. Walker represents a group of RadioShack’s U.S. independent dealers and franchisees.
