The Company’s debt issuances support its capital structure strategy objectives of funding its business and growth initiatives while minimizing its risk-adjusted cost of capital. During the fourth quarter of 2017, the Company issued $400 of five-year notes at a fixed rate of 2.25%. During the third quarter of 2017, the Company issued $500 of thirty-year notes at a fixed rate of 3.70%. The debt issuances in 2017 were under the Company’s shelf registration statement. Proceeds from the debt issuances in 2017 were used for general corporate purposes which included the retirement of commercial paper borrowings.

At December 31, 2018, the Company had access to unused domestic and foreign lines of credit of $3,023 (including under the facility discussed below) and could also issue medium-term notes pursuant to an effective shelf registration statement. In November 2018, the Company amended and restated its five-year revolving credit facility, on substantially similar terms, for a five-year term expiring November 2023 and increasing the facility’s capacity to $2,650. Commitment fees related to the credit facility are not material.

Certain agreements with respect to the Company’s bank borrowings contain financial and other covenants as well as cross-default provisions. Noncompliance with these requirements could ultimately result in the acceleration of amounts owed. The Company is in full compliance with all such requirements and believes the likelihood of noncompliance is remote.
