For 2013, management expects low- to mid-single digit organic revenue growth reflecting strong growth in Communications Systems sales and modest gains in the Battery & Energy Products business, despite continued constraints on U.S. government spending. Based on this outlook for revenue growth, ongoing productivity improvements and plans to continue prudently investing in new product development, management expects to increase operating profitability for the year and to generate a mid-single digit operating margin.Management cautions that the timing of orders and shipments may cause variability in quarterly results.
