DEBT AND FINANCING ARRANGEMENTS | DEBT AND FINANCING ARRANGEMENTS
The carrying value of our outstanding debt obligations, as of December 31, 2023 and 2022 consists of the following (in millions):
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. As of December 31, 2023, we had $2.2 billion outstanding under our U.S. commercial paper program with an average interest rate of 5.45%. The entire balance was classified as a current liability in our consolidated balance sheet as of December 31, 2023. There was no commercial paper outstanding as of December 31, 2022. The amount of commercial paper outstanding under these programs in 2024 is expected to fluctuate.
Debt Classification
As of December 31, 2023, we continued to classify our 2.200% senior notes with a principal balance of $400 million that mature in September 2024 as long-term debt in our consolidated balance sheet based on our intent and ability to refinance the debt.
Debt Repayments
On April 1, 2023, our 2.500% senior notes with a principal balance of $1.0 billion and our floating-rate senior notes with a principal balance of $500 million matured and were repaid in full. On November 15, 2023, our 0.375% Euro senior notes with a principal balance of €700 million ($749 million) matured and were repaid in full. Additionally, during 2023, we repaid $23 million of debt assumed in the Bomi Group acquisition.
Debt Issuances
On February 23, 2023, we issued two series of notes in the principal amounts of $900 million and $1.1 billion. These notes bear interest at 4.875% and 5.050%, respectively, and mature on March 3, 2033, and March 3, 2053, respectively. Interest on the notes is payable semi-annually, beginning September 2023. 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.
On March 7, 2023, we issued floating rate senior notes with a principal balance of $529 million. These notes bear interest at a rate equal to the compounded Secured Overnight Financing Rate ("SOFR") less 0.350% per year and mature on March 15, 2073. Interest on the notes is payable quarterly, beginning June 2023. These notes are callable at various times after 30 years at a stated percentage of par value and are redeemable at the option of the note holders at various times after one year at a stated percentage of par value.
Fixed-Rate Senior Notes
All of our fixed-rate notes pay interest semi-annually and allow for redemption by us at any time by paying the greater of the principal amount or a "make-whole" amount, plus accrued interest. We subsequently entered into interest rate swaps on certain of these notes, which effectively converted the fixed interest rates on the notes to variable interest rates. The average interest rates payable on the notes where fixed interest rates were swapped to variable interest rates, including the impact of the interest rate swaps, for the years ended December 31, 2023 and 2022 were as follows:
There were no outstanding interest rate swaps as of December 31, 2023.
Reference Rate Reform
Our floating-rate senior notes that mature between 2049 and 2067 initially bore interest at rates that referenced the London Interbank Offer Rate ("LIBOR") for U.S. Dollars. As part of a broader program of reference rate reform, U.S. Dollar LIBOR rates ceased to be published after June 2023. Beginning July 1, 2023, we transitioned these notes to an alternative reference rate, SOFR, which was adopted in accordance with recommendations of the Alternative Reference Rates Committee.
Floating-Rate Senior Notes
We had floating-rate senior notes in the principal amounts of $500 and $400 million that matured in 2023 and 2022, and bore interest at three-month LIBOR plus spreads of 45 and 38 basis points, respectively. The average interest rate on these notes for 2023 and 2022 was 5.32% and 1.93%, respectively.
Our outstanding floating-rate senior notes with principal amounts totaling $1.6 billion bear interest at either thirty-day, ninety-day or compounded SOFR, less a spread ranging from 4 to 35 basis points. These notes have maturities ranging from 2049 through 2073. Interest is payable monthly for notes maturing through 2053 and quarterly for notes maturing from 2064 through 2073.
The average interest rate on the outstanding floating-rate senior notes for 2023 and 2022 was 4.75% and 1.44%, respectively. These notes are callable at various times after 30 years at a stated percentage of par value, and redeemable at the option of the note holders at various times after one year at a stated percentage of par value. We have classified these floating-rate senior notes as long-term liabilities in our consolidated balance sheets, due to our intent and ability to refinance the debt if the put option is exercised.
7.620% Debentures
The $276 million debentures have a maturity of April 1, 2030. These debentures are redeemable in whole or in part at any time at our option. The redemption price is equal to the greater of the principal amount plus accrued interest, or the present value of remaining scheduled payments of principal and interest thereon discounted to the date of redemption at a benchmark treasury yield plus five basis points, plus accrued interest. Interest is payable semi-annually in April and October, and the debentures are not subject to sinking fund requirements.
Pound Sterling Notes
The Pound Sterling notes consist of two separate tranches, as follows:
•Notes with a principal amount of £66 million accrue interest at a fixed rate of 5.50% and are due in February 2031. Interest is payable semi-annually and these notes are not callable.
•Notes with a principal amount of £455 million accrue interest at a fixed rate of 5.125% and are due in February 2050. Interest is payable semi-annually. These notes are callable at our option at a redemption price equal to the greater of the principal amount plus accrued interest, or the present value of the remaining scheduled payments of principal and interest thereon discounted to the date of redemption at a benchmark U.K. government bond yield plus 15 basis points, plus accrued interest.
Euro Senior Notes
The Euro notes consist of three separate issuances, as follows:
•Notes with a principal amount of €700 million accrue interest at a fixed rate of 1.625% and are due in November 2025. Interest is payable annually. These notes are callable at our option at a redemption price equal to the greater of the principal amount, or the present value of the remaining scheduled payments of principal and interest thereon discounted to the date of redemption at a benchmark German government bond yield plus 20 basis points, plus accrued interest.
•Notes with a principal amount of €500 million accrue interest at a fixed rate of 1.00% and are due in November 2028. Interest is payable annually. These notes are callable at our option at a redemption price equal to the greater of the principal amount, or the present value of the remaining scheduled payments of principal and interest thereon discounted to the date of redemption at a benchmark comparable German government bond yield plus 15 basis points, plus accrued interest.
•Notes with a principal amount of €500 million accrue interest at a fixed rate of 1.50% and are due in November 2032. Interest is payable annually. The notes are callable at our option at a redemption price equal to the greater of the principal amount, or the present value of the remaining scheduled payments of principal and interest thereon discounted to the date of redemption at a benchmark comparable government bond yield plus 20 basis points, plus accrued interest.
Canadian Dollar Senior Notes
The Canadian Dollar notes consist of a single series, as follows:
•Notes in the principal amount of C$750 million, which bear interest at a fixed rate of 2.125% and mature in May 2024. Interest is payable semi-annually. The notes are callable at our option, in whole or in part, at the Government of Canada yield plus 21.5 basis points, and on or after the par call date at par value.
Finance Lease Obligations
We have certain property, plant and equipment subject to finance leases. For additional information on finance lease obligations, see note 11.
Facility Notes and Bonds
We have entered into agreements with certain municipalities or related entities to finance the construction of, or improvements to, facilities that support our operations in the United States. These facilities are located around airport properties in Louisville, Kentucky; Dallas, Texas; and Philadelphia, Pennsylvania. Under these arrangements, we enter into a lease or loan agreement that covers the debt service obligations on the bonds issued by these entities, as follows:
•Bonds with a principal balance of $149 million issued by the Louisville Regional Airport Authority associated with our Worldport facility in Louisville, Kentucky. The bonds are due in January 2029 and bear interest at a variable rate that is payable monthly. The average interest rates for 2023 and 2022 were 3.31% and 0.16%, respectively.
•Bonds with a principal balance of $42 million issued by the Louisville Regional Airport Authority associated with our airfreight facility in Louisville, Kentucky. The bonds are due in November 2036 and bear interest at a variable rate that is payable monthly. The average interest rates for 2023 and 2022 were 3.29% and 1.08%, respectively.
•Bonds with a principal balance of $29 million issued by the Dallas/Fort Worth International Airport Facility Improvement Corporation associated with our Dallas, Texas airport facilities. The bonds are due in May 2032 and bear interest at a variable rate that is payable quarterly. The variable cash flows on this obligation were swapped to a fixed rate of 5.11% until July 2023, when the interest rate swap was terminated. The average interest rate for 2023 was 4.42%.
•Bonds with a principal balance of $100 million issued by the Delaware County, Pennsylvania Industrial Development Authority associated with our Philadelphia, Pennsylvania airport facilities. These bonds are due in September 2045 and bear interest at a variable rate that is payable monthly. The average interest rates for 2023 and 2022 were 3.26% and 1.03%, respectively.

Sources of Credit
Letters of Credit
As of December 31, 2023, we had outstanding letters of credit totaling approximately $1.9 billion issued in connection with our self-insurance reserves and other routine business requirements. We also issue surety bonds as an alternative to letters of credit in certain instances and, as of December 31, 2023, we had $1.6 billion of surety bonds written.
Revolving Credit Facilities
We maintain two credit agreements with a consortium of banks. The first of these agreements provides revolving credit facilities of $1.0 billion and expires on December 3, 2024. Amounts outstanding under this agreement bear interest at a periodic fixed rate equal to the term SOFR rate, plus 0.10% per annum and an applicable margin based on our then-current credit rating. The applicable margin from the credit pricing grid as of December 31, 2023 was 0.70%. 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%; or (3) the Adjusted Term SOFR Rate for a one month interest period plus 1.00%, may be used at our discretion.
The second agreement provides revolving credit facilities of $2.0 billion and expires on December 7, 2026. Amounts outstanding under this facility bear interest at a periodic fixed rate equal to the term SOFR rate plus 0.10% per annum and an applicable margin based on our then-current credit rating. The applicable margin from the credit pricing grid as of December 31, 2023 was 0.875%. 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) the Adjusted Term SOFR Rate for a one-month interest period plus 1.00%, plus an applicable margin, may be used at our discretion.
If the credit ratings established by Standard & Poor's and Moody’s differ, the higher rating will be used, except in cases where the lower rating is two or more levels lower. In these circumstances, the rating one step below the higher rating will be used. We are also able to request advances under these facilities based on competitive bids for the applicable interest rate. There were no amounts outstanding under our revolving credit facilities as of December 31, 2023.
Debt Covenants
Our existing debt instruments and credit facilities subject us to certain financial covenants. As of December 31, 2023 and for all prior 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 December 31, 2023, 10% of net tangible assets is equivalent to $4.5 billion; however, we have 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 long-term debt with similar terms and maturities, the fair value of long-term debt, including current maturities, was approximately $22.1 and $18.2 billion as of December 31, 2023 and 2022, 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.
