On January 1, 2018, we adopted the Accounting Standards Codification (ASC) topic 606, Revenue from Contracts with Customers.

The Company capitalizes commissions incurred in connection with obtaining a contract. Capitalized commission fees are amortized based on the transfer of services to which the assets relate and are included in selling, general and administrative expenses. In 2019 and 2018, the amount of commissions that were capitalized and the amortization were both immaterial.

Costs incurred to obtain an intermodal, truck brokerage or logistics contract are expensed as incurred according to the practical expedient that allows contract acquisition costs to be recognized immediately if the deferral period is one year or less.

Hub offers comprehensive multimodal solutions including intermodal, truck brokerage, logistics and dedicated services. Hub has full time employees located throughout the United States, Canada and Mexico.

Intermodal. As an intermodal provider, we arrange for the movement of our customers’ freight in containers and trailers, typically over distances of 750 miles or more. We contract with railroads to provide transportation for the long-haul portion of the shipment between rail terminals. Local pickup and delivery services between origin or destination and rail terminals (referred to as “drayage”) are provided by our HGT subsidiary and third-party local trucking companies.

Truck Brokerage. We operate one of the largest truck brokerage operations in the U.S., providing customers with an over the road service option for their transportation needs. Our brokerage does not operate any trucks; instead we match customers’ needs with carriers’ capacity to provide the most effective service and price combination. We have contracts with a substantial base of carriers allowing us to meet the varied needs of our customers.

Logistics. Hub’s logistics business operates under the names Unyson Logistics (“Unyson”) and CaseStack. Unyson is comprised of a network of logistics professionals dedicated to developing, implementing and operating customized logistics solutions for customers. Unyson offers a wide range of transportation management services and technology solutions including shipment optimization, load consolidation, mode selection, carrier management, load planning and execution and web-based shipment visibility. Our multi-modal transportation capabilities include small parcel, heavyweight, expedited, less-than-truckload, truckload, intermodal, railcar and international shipping. Our CaseStack logistics business leverages proprietary technology along with collaborative relationships with retailers and logistics providers to deliver cost savings and performance-enhancing supply chain services to consumer-packaged goods clients. CaseStack contracts with third-party warehouse providers in seven markets across North America to which its customers ship their goods to be stored and eventually consolidated, along with goods from other CaseStack customers, into full truckload shipments destined to major North American retailers. CaseStack offers its customers shipment visibility, transportation cost savings, high service levels and compliance with retailers’ increasingly stringent supply chain requirements.

Dedicated Trucking. Our dedicated operation contracts with customers who seek to outsource a portion of their trucking transportation needs. We offer a dedicated fleet of equipment and drivers to each customer, as well as the management and infrastructure to operate according to the customer’s service expectations. Contracts with customers generally include fixed and variable pricing arrangements and may include charges for early termination which serves to reduce the financial risk we bear with respect to the utilization of our equipment.
