Panasonic Corp said it is transferring its Sanyo television unit in the U.S., which supplies sets to Wal-Mart Stores, to Funai Electric Co. of Japan in return for annual royalty payments. The move allows Panasonic to exit an unprofitable business. The transfer of the unit will likely be completed before the end of March, a spokesman for Panasonic said on Sunday, after the Nihon Keizai newspaper reported it would sell the business to Funai Electric . Shedding the Sanyo business fits with Panasonic’s strategy of pulling back for consumer electronics in a bid to improve profitability.
