[1] | (1) The carrying value of the euro-denominated 1.50% notes due May 2023 and 1.875% notes due November 2026 will fluctuate with changes in the euro exchange rate. The carrying value of these euro-denominated borrowings have been designated as non-derivative net investment hedges of a portion of the Company's net investments in euro functional-currency denominated subsidiaries to offset foreign currency fluctuations. During the twelve months ended December 31, 2017, pre-tax losses of $180 million were recognized in "Other comprehensive income (loss)" for revaluation of these notes.
