LONDON--U.K. retailer Marks & Spencer Group PLC (MAKSY) is being eyed as a potential 6 billion pound (9.4 billion dollar) bid target after a 50% slump in its shares since 2007, the Sunday Telegraph reports, citing banking sources. The paper says bankers including Bank of America Merrill Lynch (BAC) have in recent weeks assessed the possibility of providing debt finance for a speculative bid. One private equity firm is reported to be considering a public-to-private takeover of the retailer. A spokeswoman for Marks & Spencer declined to comment. A representative for Bank of America wasn't immediately available to comment.
