SEGMENT INFORMATION

We have two reportable operating segments for purposes of ASC 280-10-50 "Segment Reporting": (1) IoT Products & Services (formerly M2M), and (2) IoT Solutions (formerly Solutions). Our segments are described below:

IoT Products & Services

Our IoT Products & Services segment is composed of the following communications products and development services and includes our recent acquisition of Accelerated:


•	Cellular routers and gateways;


•	Radio frequency (RF) which include our XBee^® modules as well as other RF solutions;


•	Embedded products include Digi Connect^® and Rabbit^® embedded systems on module and single board computers;

•	Support services which offers various levels of technical services for development assistance, consulting and training.

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. 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 SmartSense by Digi™, formerly 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.
