Impact of Glencore Rail (NSW) Pty Limited (GRail) Acquisition on G&W Financial Presentation

In conjunction with the December 1, 2016 acquisition of GRail, G&W issued a 48.9% equity stake in G&W’s Australian subsidiary, G&W Australia Holdings LP (GWA), the holding company for all of G&W's Australian businesses, to Macquarie Infrastructure and Real Assets (MIRA). G&W retained a 51.1% interest in GWA and continues to consolidate 100% of GWA in its financial statements and reports a noncontrolling interest for MIRA’s 48.9% equity ownership. As a result, G&W’s second quarter 2017 operating income includes 100% of the Australian business, while net income attributable to G&W reflects its 51.1% ownership position in the Australian business.

Prior to the GRail acquisition, G&W's Australian Operations provided rail operator services to GRail, which were recorded as freight-related revenues. These freight-related services continued post acquisition, but are eliminated in consolidation. Revenues from the GRail acquisition are now included in G&W’s consolidated freight revenues from new operations.
