Reported second quarter sales at HJ Heinz decreased to $2.30 billion (€2.6 billion) from $2.34 billion last year, as increased volume and acquisitions were offset by the impact of unfavourable foreign exchange translation rates, divestitures and lower pricing. On a constant currency basis, core operating income rose to 17 per cent, it said. Core operating for the second quarter rose 9.9 per cent to $459.5 million from $418 million last year.
