Debt and lines of credit Debt and lines of credit
Short-term borrowings
We maintain a line of credit to support commercial paper borrowings, if any, and to provide additional liquidity through bank loans. As of December 31, 2021, we had a variable-rate revolving credit facility from a consortium of investment-grade banks that allows us to borrow up to $2 billion until March 2024. As of December 31, 2021, our credit facility was undrawn, and we had no commercial paper outstanding.
Long-term debt
In February 2021, we retired $550 million of maturing debt.

In September 2021, we issued three series of senior unsecured notes for an aggregate principal amount of $1.5 billion, consisting of $500 million of 1.125% notes due in 2026, $500 million of 1.90% notes due in 2031 and $500 million of 2.70% notes due in 2051. We incurred $10 million of issuance costs. The proceeds of the offering were $1.5 billion, net of the original issuance discounts, which will be used for general corporate purposes.
In March 2020, we issued a principal amount of $750 million of fixed-rate, long-term debt due in 2025. We incurred $4 million of issuance costs. The proceeds of the offering were $749 million, net of the original issuance discount, and were used for general corporate purposes and the repayment of maturing debt.

In May 2020, we issued a principal amount of $750 million of fixed-rate, long-term debt due in 2030. We incurred $5 million of issuance costs. The proceeds of the offering were $749 million, net of the original issuance discount, and were used for general corporate purposes.
In March 2019, we issued a principal amount of $750 million of fixed-rate, long-term debt due in 2039. We incurred $7 million of issuance costs. The proceeds of the offering were $743 million, net of the original issuance discount, and were used for general corporate purposes.
