IoT Solutions

We have formed the IoT Solutions segment primarily through four acquisitions: the October 2015 acquisition of Bluenica, the November 2016 acquisition of FreshTemp, the January 2017 acquisition of SMART Temps and the October 2017 acquisition of TempAlert, LLC (TempAlert). Our IoT Solutions segment offers wireless temperature and other environmental condition monitoring services as well as employee task management services. These products and services are provided to food service, transportation, education, healthcare and pharma, and industrial markets and are marketed as Digi Smart Solutions™.

We measure our segment results primarily by reference to revenue and operating income (loss). IoT Solutions revenue includes both product and service revenue. Certain costs incurred at the corporate level are allocated to our segments. These costs include information technology, employee benefits and shared facility services. The information technology and shared facility costs are allocated based on headcount and the employee benefits costs are allocated based on compensation costs.
