Income Statement Detail
Gross margin was 22.2 percent compared to 23.3 percent in the year ago quarter, primarily caused by a product mix shift within our Electrical and Electronic Wire and Cable and Enterprise Cabling and Security Solutions segments. Strong cost management resulted in flat operating expense year-over-year and a 50 basis point improvement in operating expense as a percent of sales, excluding the above mentioned charges.
