By ANNE D'INNOCENZIONEW YORK (AP) â¿¿ There won't be an easy fix for J.C. Penney â¿¿ if it is even fixable. As Mike Ullman takes the reins again less than two years after his departure, he faces a Herculean task to undo the mess left by his predecessor, Ron Johnson, who was ousted Monday. With the department stores in the middle of a disastrous overhaul that has driven away shoppers, the 66-year-old Ullman has to quickly figure out what parts of Johnson's legacy to keep and what to trash. The overarching question is whether the century-old retailer can be saved at all. Very few retailers have recovered from sales declines of 25 percent in a single year that Penney suffered under Johnson's watch. In fact, the retailer's stock price dropped nearly 10 percent to $14.18 Tuesday as investors' worries escalate about Penney's future. "Ullman can't go back to the old ways, but he can't do what Ron Johnson did," said Ron Friedman, head of the retail and consumer products group at Marcum LLP, a national accounting and consulting firm. "I think there will be a combination of the two. But he has to make some quick moves." Apparently, the company's board of directors felt Ullman, who served as Penney's CEO for seven years and is known for strong relationships with suppliers and calm, steady execution, would be the best choice to secure the company's future right now. The board's firing of Johnson, the mastermind behind Apple Inc.'s successful retail stores who held the Penney job for 17 months, comes after a growing chorus of critics called for Johnson's resignation as they lost faith in his aggressive overhaul. The rapid-fire changes included getting rid of coupons and most discounts in favor of everyday low prices, bringing in new brands and remaking its outdated stores. Johnson's goal was to reinvent the stodgy retailer into a mini-mall of hip specialty shops.
