Public companies are required to report financial and descriptive information about their reportable operating segments as required by FASB ASC Topic No. 280, Segment Reporting. The Company has two primary business units based on how management internally evaluates separate financial information, business activities and management responsibility. Wireless includes our NetWise®, CommSuite®, SafePath®, and ViewSpot™ family of products. Graphics includes our consumer-based products: Poser®, Moho®, MotionArtist®, Rebelle, PhotoDonut and StuffIt®, and through April 2018 included third-party software products under the Clip Studio® brand, which we distributed under an agreement which expired in October 2017 and permitted certain post-termination distribution rights until April 2018.

The Company does not separately allocate operating expenses to these business units, nor does it allocate specific assets. Therefore, business unit information reported includes only revenues.
