Executives at Bed Bath & Beyond say they reported concerns that their chief financial officer, Gustavo Arnal, was feeling’stressed’ with the current financial crisis at the company and his own share dealings coming under scrutiny. Board member Sue Gove, who began acting as interim chief executive officer in June, believed Arnal to be overwhelmed but feared replacing the CFO while the company was in the middle of raising money. A former CEO of Avon Products, Jan Zijderveld, who dined with Arnal and his wife in July, said it was clear the 52-year-old was under pressure and said as much to him. On August 31, Arnal revealed how the company had secured fresh financing and briefed investors on a major restructuring plan. . . .
