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 historically had two primary business units based on how management internally evaluates separate financial information, business activities and management responsibility: Wireless and Graphics. Wireless primarily includes our SafePath®, CommSuite®, and ViewSpot® family of products. Graphics includes our consumer-based products: Moho®, MotionArtist®, Rebelle, PhotoDonut and StuffIt®, Poser® (through June 2019), and Clip Studio® (through April 2018).

With the more recent divestitures of Poser and Clip Studio, the Graphics business has become insignificant in relation to total consolidated revenues and no longer qualifies as a reportable operating segment. Therefore, the Company will disclose only one reportable operating segment, Wireless, and the following disclosures reflect this change.

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.

Revenues generated from our sales to Sprint and their respective affiliates in the Wireless business segment accounted for 84% and 81% of the Company’s total revenues for fiscal years 2019 and 2018, respectively. This customer comprised 92% and 82% of our accounts receivable as of December 31, 2019 and 2018, respectively. This major customer could reduce their orders of our products in favor of a competitor's product or for any other reason. The loss of this major customer or decisions by a significant customer to substantially reduce purchases could have a material adverse effect on our business.

During the years ended December 31, 2019 and 2018, the Company operated in three geographic locations: the Americas, EMEA (Europe, the Middle East, and Africa), and Asia Pacific. Revenues attributed to the geographic location of the customer’s bill-to address were as follows (in thousands):
