Adtalem Global Education Inc

18. Segment Information

We present three reportable segments as follows:

Chamberlain – This segment includes the operations of Chamberlain, which offers degree and certificate programs in the nursing and health professions postsecondary education industry.

Walden – This segment includes the operations of Walden, which offers degree and certificate programs, including those in nursing, education, counseling, business, psychology, public health, social work and human services, public administration and public policy, and criminal justice.

Medical and Veterinary – This segment includes the operations of AUC, RUSM, and RUSVM, collectively referred to as the “medical and veterinary schools,” which offers degree and certificate programs in the medical and veterinary postsecondary education industry.

These segments are consistent with the method by which the Chief Operating Decision Maker (Adtalem’s Chairman and Chief Executive Officer) evaluates performance and allocates resources. Performance evaluations are based on each segment’s adjusted operating income. Adjusted operating income excludes special items, which consists of restructuring expense, business integration expense, amortization of acquired intangible assets, litigation reserve, asset impairments, strategic advisory costs, loss on assets held for sale, and debt modification costs. Adtalem’s management excludes these items from its review of the results of the operating segments for purposes of measuring segment profitability and allocating resources. “Home Office” includes activities not allocated to a reportable segment and is included to reconcile segment results to the Consolidated Financial Statements. Total assets by segment is not presented as our CODM does not review or allocate resources based on segment assets. The accounting policies of the segments are the same as those described in Note 2 “Summary of Significant Accounting Policies.”
