It was a steady performance highlighted by improving operational efficiency and consistent service execution for Con-way Freight. Our focus on safety continue to return encouraging results as the number of accidents and injuries year-to-date were down 13% and 25%, respectively compared to the first half of 2011. We remain diligent in managing our cost and our lean continuous improvement practices are helping our employees aim more opportunities to eliminate waste and increase efficiencies.
