[1] The impact on interest expense, net at June 30, 2015 related to derivative contracts entered into to offset fluctuations in the underlying non-functional currency cash balances and intercompany loans at June 30, 2015 is due to increased foreign exchange exposure and higher volatility in currencies during the year, which is more than offset by the revaluation of underlying non-functional currency cash balances.
