Congdon, President and Chief Executive Officer of Old Dominion. “During the second quarter, we continued to build significant momentum in efficiency and profitability, while continuing to win additional market share. We attribute our continued success to our highly efficient operating structure and our commitment to provide industry-leading service at a fair and equitable price. We are excited about the opportunity these fundamentals provide, which should allow us to further expand our market share and achieve our long-term growth objectives. “Our revenue growth for the second quarter of 2012 reflected a 9.0% increase in tonnage compared with the second quarter of 2011 that resulted from an 8.6% increase in shipments and a 0.4% increase in weight per shipment. Revenue per hundredweight rose 3.4% for the latest quarter from the comparable prior-year quarter, or 4.1% excluding fuel surcharges, despite the generally negative impact on revenue per hundredweight resulting from the increase in our weight per shipment and a 1.4% decline in our length of haul.
