We have four reportable business segments – Intermodal (JBI), Dedicated Contract Services (DCS), Integrated Capacity Solutions (ICS), and Truckload (JBT) – which are based primarily on the services each segment provides. The JBI segment includes freight that is transported by rail over at least some portion of the movement and also includes certain repositioning truck freight moved by JBI equipment or third-party carriers, when such highway movement is intended to direct JBI equipment back toward intermodal operations. DCS segment business includes company-owned and customer-owned, DCS-operated revenue equipment and employee drivers assigned to a specific customer, traffic lane, or service. DCS operations usually include formal, written longer-term agreements or contracts that govern services performed and applicable rates. ICS provides non-asset and asset-light transportation solutions to customers through relationships with third-party carriers and integration with JBHT-owned equipment. ICS services include flatbed, refrigerated, and LTL, as well as a variety of dry-van and intermodal solutions. JBT business includes full-load, dry-van freight that is typically transported utilizing company-owned or company-controlled revenue equipment. This freight is typically transported over roads and highways and does not move by rail. All transactions between reporting segments are eliminated in consolidation.
