The entity is named GX Technology Processamento de Dados Ltda. The Company owns a 70% interest, and Bratexco owns a 30% interest. Bratexco’s cash contributions were $0.3 million.

     The Company consolidates the assets, liabilities, revenues and expenses of all majority-owned subsidiaries over which the Company exercises control or for which the Company has a controlling financial interest. Bratexco’s interest in results of operations related to the entity is reflected in “Net income attributable to noncontrolling interest” in the condensed consolidated statements of operations and its interest in the assets and liabilities related to the entity is reflected in “Noncontrolling interest” in the condensed consolidated balance sheet.
