On November 16, 2017, the Company entered into an Underwriting Agreement with BBVA Securities Inc., BNP Paribas Securities Corp., Citigroup Global Markets Inc., and Wells Fargo Securities, LLC, as representatives of the several underwriters listed therein (collectively, the “Underwriters”), for the issuance and sale by the Company of $600 million aggregate principal amount of its 3.150% notes due 2024 (the “Notes”). The closing of the offering occurred on November 21, 2017.

The Notes were issued pursuant to an indenture, dated as of November 21, 2017, between the Company and The Bank of New York Mellon, as trustee (the “Indenture”), as supplemented by the First Supplemental Indenture, dated as of November 21, 2017 (the “First Supplemental Indenture”).
