Debt Classification As of December 31, 2023, we had approximately $2.8 billion of debt maturing within the next 12 months, including (i) $1.6 billion of tax-exempt bonds with term interest rate periods that expire within the next 12 months, which is prior to their scheduled maturities; (ii) $859 million of short-term borrowings under our commercial paper program (net of related discount on issuance); (iii) $175 million of other debt with scheduled maturities within the next 12 months, including $60 million of tax-exempt bonds, and (iv) $156 million of 3.5% senior notes that mature in May 2024. As of December 31, 2023, we have classified $2.4 billion of debt maturing in the next 12 months as long-term because we have the intent and ability to refinance these borrowings on a long-term basis as supported by the forecasted available capacity under our $3.5 billion long-term U.S. and Canadian revolving credit facility (“$3.5 billion revolving credit facility”), as discussed below. The remaining $334 million of debt maturing in the next 12 months is classified as current obligations. Access to and Utilization of Credit Facilities, Commercial Paper Program and Term Loan $3.5 Billion Revolving Credit Facility — Our $3.5 billion revolving credit facility, maturing May 2027, provides us with credit capacity to be used for cash borrowings, to support letters of credit and to support our commercial paper program. The agreement includes a $1.0 billion accordion feature that may be used to increase total capacity in future periods, and we have the option to request up to two one-year extensions. Waste Management of Canada Corporation and WM Quebec Inc., each an indirect wholly-owned subsidiary of WMI, are borrowers under the $3.5 billion revolving credit facility, and the agreement permits borrowing in Canadian dollars up to the U.S. dollar equivalent of $375 million, with such borrowings to be repaid in Canadian dollars. WM Holdings, a wholly-owned subsidiary of WMI, guarantees all the obligations under the $3.5 billion revolving credit facility. The interest rates we pay on outstanding U.S. or Canadian loans are based on a secured overnight financing rate administered by the Federal Reserve Bank of New York (“SOFR”) or the Canadian Dollar Offered Rate (“CDOR”), respectively, plus a spread depending on WMI’s senior public debt rating assigned by Moody’s Investors Service, Inc. and Standard and Poor’s Global Ratings. The spread above SOFR or CDOR can range from 0.585% to 1.025% per annum, plus a credit adjustment spread of 0.10% per annum on SOFR-based rates (the “SOFR Credit Adjustment Spread”) to account for the transition from the use of LIBOR to SOFR in such rate calculations. We also pay certain other fees set forth in the $3.5 billion revolving credit facility agreement, including a facility fee based on the aggregate commitment, regardless of usage. As of December 31, 2023, we had no outstanding borrowings under this facility. We had $859 million of outstanding borrowings (net of related discount on issuance) under our commercial paper program and $180 million of letters of credit issued, both supported by the facility, leaving unused and available credit capacity of $2.5 billion as of December 31, 2023. Commercial Paper Program — We have a commercial paper program that enables us to borrow funds for up to 397 days at competitive interest rates. The rates we pay for outstanding borrowings are based on the term of the notes. The commercial paper program is fully supported by our $3.5 billion revolving credit facility. As of December 31, 2023, we had $859 million of outstanding borrowings (net of related discount on issuance) under our commercial paper program. Term Loan — In May 2022, we entered into a $1.0 billion, two-year, U.S. term credit agreement maturing May 2024 (“Term Loan”) to support general corporate purposes. WM Holdings guaranteed all obligations under our Term Loan. The interest rate we paid on our Term Loan was generally based on SOFR, plus a spread depending on WMI’s senior public debt rating assigned by Moody’s Investors Service, Inc. and Standard and Poor’s Global Ratings. Our Term Loan had a contractual maturity of May 2024, but we elected to repay all outstanding borrowings under our Term Loan in August 2023 with proceeds from our July 2023 senior notes issuance, which is discussed further below. Other Letter of Credit Lines — As of December 31, 2023, we had utilized $834 million of other uncommitted letter of credit lines with terms extending through December 2027. Debt Borrowings and Repayments Commercial Paper Program — During the year ended December 31, 2023 we made cash repayments of $18.7 billion, which were partially offset by $17.8 billion of cash borrowings (net of related discount on issuance). A portion of these borrowings were repaid with proceeds from our senior note issuances as discussed below. Senior Notes — In February 2023, WMI issued $750 million and $500 million of 4.625% senior notes due February 2030 and February 2033, respectively, the net proceeds of which were $1.24 billion. We used the net proceeds to reduce outstanding borrowings under our commercial paper program, repay $500 million of WMI’s 2.4% senior notes upon maturity in May 2023, and for general corporate purposes, including our planned and ongoing investments in our Recycling Processing and Sales and WM Renewable Energy segments. ​ In July 2023, WMI issued $750 million and $1.25 billion of 4.875% senior notes due February 2029 and February 2034, respectively, the net proceeds of which were $1.97 billion. We used the net proceeds to reduce outstanding borrowings under our commercial paper program, repay $1.0 billion of outstanding borrowings under our Term Loan and for general corporate purposes. ​ Term Loan — In August 2023, we repaid $1.0 billion of outstanding borrowings under our Term Loan with proceeds from our July 2023 senior notes issuance discussed above and contemporaneously terminated the facility. Tax-Exempt Bonds — We issued $300 million of tax-exempt bonds in 2023. The proceeds from the issuance of these bonds were deposited directly into a restricted trust fund to be used for the specific purpose for which the money was raised, which is generally to finance expenditures for solid waste disposal facility, recycling facility and renewable natural gas facility construction and development. In 2023, we also repaid $65 million of our tax-exempt bonds with available cash at their scheduled maturities. Financing Leases and Other — The increase in our financing leases and other debt obligations in 2023 is primarily related to a note payable associated with our low-income housing investment discussed in Note 8, which increased our debt obligations by $183 million, and $93 million primarily related to non-cash financing leases. The increase in our debt obligations was partially offset by $120 million of cash repayments of debt at maturity. Scheduled Debt Payments Principal payments of our debt for the next five years and thereafter, based on scheduled maturities are as follows: $1,192 million in 2024, $1,355 million in 2025, $713 million in 2026, $1,198 million in 2027, $892 million in 2028 and $11,002 million thereafter. Our recorded debt and financing lease obligations include non-cash adjustments associated with debt issuance costs, discounts and fair value adjustments attributable to terminated interest rate derivatives, which have been excluded from these amounts because they will not result in cash payments. As discussed above, we have the intent and ability to refinance certain 2024 scheduled maturities on a long-term basis, including portions of our commercial paper borrowings and our $156 million of 3.5% senior notes that mature in May 2024. See Note 7 below for further discussion of our financing lease arrangements. Secured Debt Our debt balances are generally unsecured, except for financing lease obligations and the notes payable associated with our investments in low-income housing properties. See Notes 8 and 18 for additional information related to these investments. Debt Covenants The terms of certain of our financing arrangements require that we comply with financial and other covenants. Our most restrictive financial covenant is the one contained in our $3.5 billion revolving credit facility, which sets forth a maximum total debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization ratio (the “Leverage Ratio”). This covenant requires that the Leverage Ratio for the preceding four fiscal quarters will not be more than 3.75 to 1, provided that if an acquisition permitted under the $3.5 billion revolving credit facility involving aggregate consideration in excess of $200 million occurs during the fiscal quarter, the Company shall have the right to increase the Leverage Ratio to 4.25 to 1 during such fiscal quarter and for the following three fiscal quarters (the “Elevated Leverage Ratio Period”). There shall be no more than two Elevated Leverage Ratio Periods during the term of the $3.5 billion revolving credit facility, and the Leverage Ratio must return to 3.75 to 1 for at least one fiscal quarter between Elevated Leverage Ratio Periods. The calculation of all components used in the Leverage Ratio covenant are as defined in the $3.5 billion revolving credit facility. As of December 31, 2023 and 2022, we were in compliance with our Leverage Ratio covenant. Our $3.5 billion revolving credit facility, senior notes and other financing arrangements also contain certain restrictions on the ability of the Company’s subsidiaries to incur additional indebtedness as well as restrictions on the ability of the Company and its subsidiaries to, among other things, incur liens, engage in sale-leaseback transactions and engage in mergers and consolidations. We monitor our compliance with these restrictions, but do not believe that they significantly impact our ability to enter into investing or financing arrangements typical for our business. As of December 31, 2023 and 2022, we were in compliance with all covenants and restrictions under our financing arrangements, in addition to our Leverage Ratio covenant, that may have a material effect on our Consolidated Financial Statements. ​ Interest Rate Derivatives During 2023, we entered into treasury rate locks with a total notional value of $800 million to secure underlying interest rates associated with our senior notes issuances discussed above. We designated our treasury rate locks as cash flow hedges. These treasury rate locks were terminated contemporaneously with the related issuances of senior notes in 2023, and we received cash of $19 million to settle the related assets. The deferred gains are being amortized as a decrease to interest expense over the ten-year life of the related senior notes issuances using the effective interest method.
