J.C. Penney Co. has disclosed some private figures to shareholders after a senior executive at the company mentioned the figure in a private email to avoid any issues with Wall Street regulators. The executive accidentally told a Wall Street securities analyst the company’s sales results for its fiscal first quarter through mid-April, a number that has yet to be publicly reported, according to the retailer's filing with the SEC. The retailer forecasts that sales for the three months ending April will increase 3.5% to 4.5%.
