[1] (1) For the years ended December 31, 2017, 2016 and 2015, we paid US$ 17.4 million, US$ 33.3 million and US$ 3.5 million, respectively, of interest and Guarantee Fees associated with the 2018 Euro Term Loan, both as defined in Note 5, "Long-term Debt and Other Financing Arrangements". These payments were allocated to net cash (used in) / provided by discontinued operations - operating activities in our Consolidated Statements of Cash Flows as we are required to apply the expected proceeds from the sale of our Croatia and Slovenia operations towards the repayment of the remaining principal amounts owing in respect of the 2018 Euro Term Loan (see Note 5, "Long-term Debt and Other Financing Arrangements").
