The battle for Federated Department Stores showed signs of intensifying as the retailer and R. H. Macy & Co. said they were beginning talks on a possible sweetening of Macy’s $6.3-billion offer for Federated. Federated also said its board authorized company representatives to meet with Campeau Corp. to discuss the Toronto-based developer’s competing $6.53-billion tender offer. In a statement, Federated said its directors would meet again by Wednesday and that Macy Chairman Edward S. Finkelstein and his counterpart at Campeau, Robert Campeau, would both be allowed to address the board.
