Effective January 1, 2019, the Company substantially completed its Organizational Consolidation changing from a holding company that previously owned a portfolio of companies to an operating company structure that provides NET services and has an investment in Matrix. As a result, beginning January 1, 2019, the Company’s chief operating decision maker reviews financial performance and allocates resources based on two segments as follows:

•NET Services - which operates primarily under the brands LogistiCare and Circulation, is the largest manager of NET programs for state governments and MCOs in the U.S and includes the Company’s activities for executive, accounting, finance, internal audit, tax, legal, certain strategic and development functions and the Company’s captive insurance company.

•Matrix Investment - which consists of a minority investment in Matrix, provides a broad array of assessment and care management services that improve health outcomes for individuals and financial performance for health plans. Matrix’s national network of community-based clinicians deliver in-home services while its fleet of mobile health clinics provide community-based care with advance diagnostic capabilities.

We have reclassified prior period segment amounts to conform to the current presentation, which are summarized as follows:
