Segment and Geographic Information |
Segment and Geographic Information | 13. Segment and Geographic Information As a result of the acquisition of GetSmarter on July 1, 2017, the Company's operations consist of two operating segments and two reportable segments: the Graduate Program Segment and the Short Course Segment. The Company's Graduate Program Segment provides services to well-recognized nonprofit colleges and universities primarily in the United States to enable the online delivery of graduate programs. The Company's Short Course Segment provides premium online short courses to working professionals. The reportable segments represent businesses for which separate financial information is utilized by the chief operating decision maker for the purpose of allocating resources and evaluating performance. During the year ended December 31, 2017, four university clients in the Graduate Program Segment each accounted for 10% or more of the Company's consolidated revenue, as follows: $77.6 million, $48.2 million, $30.1 million and $28.3 million, which equals 27%, 17%, 11% and 10% of the Company's consolidated revenue, respectively. During the year ended December 31, 2016, three university clients in the Graduate Program Segment each accounted for 10% or more of the Company's consolidated revenue, as follows: $71.0 million, $36.7 million and $22.1 million, which equals 35%, 18% and 11% of the Company's consolidated revenue, respectively. As of December 31, 2017, two university clients in the Graduate Program Segment each accounted for 10% or more of the Company's consolidated accounts receivable balance, as follows: $9.4 million and $2.0 million, which equals 67% and 14% of the Company's consolidated accounts receivable, respectively. As of December 31, 2016, two university clients in the Graduate Program Segment each accounted for 10% or more of the Company's consolidated accounts receivable balance, as follows: $5.8 million and $1.4 million, which equals 74% and 17% of the Company's consolidated accounts receivable, respectively. For the Company's Short Course Segment, revenue and accounts receivable are derived from individual students, rather than directly from university clients. For the year ended December 31, 2017, revenue associated with the Company's three largest university clients in this segment accounted for approximately 82% of the segment's revenue, which was less than 10% of the Company's consolidated revenue on a combined basis. As of December 31, 2017, none of the student accounts receivable balances within this segment accounted for more than 10% of the Company's consolidated accounts receivable.
