[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 six months ended June 30, 2018, pre-tax gains of $39 million were recognized in other comprehensive income ("OCI") for revaluation of these notes.
