[1] | The decrease in operating income and net income for the United States Operations in fiscal year 2016 compared to fiscal year 2015 was primarily a result of the increase in operating expenses related to intercompany transactions with the Company's Colombia subsidiary of approximately $10.9 million. This activity results in reductions to taxable income in the U.S. that lowered the provision for income taxes by approximately $3.9 million.
[2] | The reconciling items reflect the amount eliminated on consolidation of intersegment transactions.
