Commercial Paper

We are authorized to borrow up to $10.0 billion under a U.S. commercial paper program and €5.0 billion (in a variety of currencies) under a European commercial paper program. We had the following amounts outstanding under these programs as of June 30, 2020: $1.7 billion with an average interest rate of 0.54% and €228 million ($256 million) with an average interest rate of -0.41%. As of June 30, 2020, we have classified the entire commercial paper balance as a current liability on our consolidated balance sheets.

Debt Classification

We have classified a portion of our debt instruments that mature within twelve months and certain floating-rate senior notes with put options as long-term due to our intent and ability to refinance the debt.

Debt Repayments

On April 1, 2020, our 8.375% senior notes with a principal balance of $424 million matured and were repaid in full.

Debt Issuances

On March 24, 2020 we issued four series of notes, in the following principal amounts: $1.0 billion, $750 million, $500 million and $1.25 billion. These notes bear interest at 3.90%, 4.45%, 5.20% and 5.30%, respectively, and will mature on April 1, 2025, April 1, 2030, April 1, 2040 and April 1, 2050, respectively. Interest on the notes is payable semi-annually, beginning October 2020. Each series of notes is callable at our option at a redemption price equal to the greater of 100% of the principal amount, or the sum of the present values of scheduled payments of principal and interest, plus accrued and unpaid interest.

In such event, the present values of scheduled principal and interest payments are discounted to the redemption date on a semi-annual basis at the discount rate of the Treasury Rate plus 50 basis points, and are determined as follows:

•On the 3.90% notes, payments from the redemption date until one month prior to maturity

•On the 4.45% notes, payments from the redemption date until three months prior to maturity

•On the 5.20% and 5.30% notes, payments from the redemption date until six months prior to maturity

Sources of Credit

We maintain two credit agreements with a consortium of banks. One of these agreements provides revolving credit facilities of $2.0 billion, and expires on December 8, 2020. Generally, amounts outstanding under this facility bear interest at a periodic fixed rate equal to LIBOR for the applicable interest period and currency denomination, plus an applicable margin. Alternatively, a fluctuating rate of interest equal to the highest of (1) the rate of interest last quoted by The Wall Street Journal as the prime rate in the United States; (2) the Federal Funds effective rate plus 0.50%; and (3) LIBOR for a one month interest period plus 1.00%, plus an applicable margin, may be used at our discretion. In each case, the applicable margin for advances bearing interest based on LIBOR is a percentage determined by quotations from Markit Group Ltd. for our one-year credit default swap spread, subject to a minimum rate of 0.25% and a maximum rate of 1.00%. The applicable margin for advances bearing interest based on the prime rate is 1.00% below the applicable margin for LIBOR advances (but not lower than 0%). We are also able to request advances under this facility based on competitive bids for the applicable interest rate. There were no amounts outstanding under this facility as of June 30, 2020.

The second agreement provides revolving credit facilities of $2.5 billion, and expires on December 11, 2023. Generally, amounts outstanding under this facility bear interest at a periodic fixed rate equal to LIBOR for the applicable interest period and currency denomination, plus an applicable margin. Alternatively, a fluctuating rate of interest equal to the highest of (1) the rate of interest last quoted by The Wall Street Journal as the prime rate in the United States; (2) the Federal Funds effective rate plus 0.50%; and (3) LIBOR for a one month interest period plus 1.00%, plus an applicable margin, may be used at our discretion. In each case, the applicable margin for advances bearing interest based on LIBOR is a percentage determined by quotations from Markit Group Ltd. for our one-year credit default swap spread, interpolated for a period from the date of determination of such credit default swap spread in connection with a new interest period until the latest maturity date of this facility then in effect (but not less than a period of one year). The minimum applicable margin rate is 0.10% and the maximum applicable margin rate is 0.75% per annum. The applicable margin for advances bearing interest based on the prime rate is 1.00% below the applicable margin for LIBOR advances (but not less than 0%). We are also able to request advances under this facility based on competitive bids. There were no amounts outstanding under this facility as of June 30, 2020.

Debt Covenants

Our existing debt instruments and credit facilities subject us to certain financial covenants. As of June 30, 2020, and for all periods presented, we have satisfied these financial covenants. These covenants limit the amount of secured indebtedness that we may incur, and limit the amount of attributable debt in sale-leaseback transactions, to 10% of net tangible assets. As of June 30, 2020, 10% of net tangible assets was equivalent to $4.0 billion; however, we had no covered sale-leaseback transactions or secured indebtedness outstanding. We do not expect these covenants to have a material impact on our financial condition or liquidity.

Fair Value of Debt

Based on the borrowing rates currently available to us for debt with similar terms and maturities, the fair value of long-term debt, including current maturities, was approximately $30.6 and $26.9 billion as of June 30, 2020 and December 31, 2019, respectively. We utilized Level 2 inputs in the fair value hierarchy of valuation techniques to determine the fair value of all of our debt instruments.
