The following table summarizes the major components of debt as of each balance sheet date (in millions) and provides the maturities and interest rate ranges of each major category as of June 30, 2022:

(a)	Excluding our landfill financing leases, the maturities of our financing leases and other debt obligations extend through 2059.

Debt Classification

As of June 30, 2022, we had approximately $2.4 billion of debt maturing within the next 12 months, including (i) $1.0 billion of short-term borrowings under our commercial paper program (net of related discount on issuance); (ii) $625 million of tax-exempt bonds with term interest rate periods that expire within the next 12 months, which is prior to their scheduled maturities; (iii) $500 million of 2.4% senior notes that mature in May 2023 and (iv) $226 million of other debt with scheduled maturities within the next 12 months, including $111 million of tax-exempt bonds. As of June 30, 2022, we have classified $2.1 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 $231 million of debt maturing in the next 12 months is classified as current obligations.

Additionally, as of June 30, 2022, we also had $54 million of variable-rate tax-exempt bonds with long-term scheduled maturities which are supported by letters of credit under our $3.5 billion revolving credit facility. The interest rates on our variable-rate tax-exempt bonds reset on a weekly basis through a remarketing process. All recent tax-exempt bond remarketings have successfully placed Company bonds with investors at market-driven rates and we currently expect future remarketings to be successful. However, if the remarketing agent is unable to remarket our bonds, the remarketing agent can put the bonds to us. In the event of a failed remarketing, we have the availability under our $3.5 billion revolving credit facility to fund these bonds until they are remarketed successfully. Accordingly, we have classified the $54 million of variable-rate tax-exempt bonds with maturities of more than one year as long-term in our Condensed Consolidated Balance Sheet.

Access to and Utilization of Credit Facilities and Commercial Paper Program

$3.5 Billion Revolving Credit Facility — In May 2022, we amended and restated our $3.5 billion U.S. and Canadian revolving credit facility extending the term through May 2027. 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 $3.5 billion revolving credit facility provides us with credit capacity to be used for cash borrowings, to support letters of credit or to support our commercial paper program. The interest rates we pay on outstanding U.S. or Canadian loans are generally 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 June 30, 2022, we had no outstanding borrowings under this facility. We had $166 million of letters of credit issued and $1.0 billion of outstanding borrowings (net of related discount on issuance) under our commercial paper program, both supported by the facility, leaving unused and available credit capacity of $2.3 billion as of June 30, 2022.

Pursuant to the terms of the $3.5 billion revolving credit facility, and as a mechanism to align our environmental, social and governance (“ESG”) focus and strategy across external and internal stakeholders, the Company, in consultation with one or more banks selected by the Company to be the sustainability coordinator under the applicable credit agreement (the “Sustainability Coordinator”), has the ability to establish specified key performance indicators (“KPIs”) with respect to certain ESG targets of the Company and its subsidiaries. The Sustainability Coordinator, the Company and the administrative agent may amend the credit agreement, unless such amendment is objected to by banks holding more than 50% of the commitments under such credit agreement, solely for the purpose of incorporating the KPIs so that certain adjustments to the otherwise applicable fees or interest rates may be made based on our performance against the KPIs.

$1.0 Billion, Two-Year, Term Credit Agreement — In May 2022, we entered into a $1.0 billion, two-year, U.S. term credit agreement (“Term Loan”) to be used for general corporate purposes. The interest rate we pay on our outstanding balance is 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. The spread above SOFR can range from 0.50% to 0.90% per annum, plus the SOFR Credit Adjustment Spread. As discussed above with respect to our $3.5 billion revolving credit facility, the Term Loan also permits the Company to pursue an amendment of the credit agreement to incorporate certain ESG KPIs and related adjustments to applicable fees or interest rates based on performance against the KPIs. As of June 30, 2022, we had $1.0 billion of outstanding borrowings under our Term Loan. WM Holdings also guarantees all of the obligations under the Term Loan.

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 June 30, 2022, we had $1.0 billion of outstanding borrowings (net of related discount on issuance) under our commercial paper program.

Other Letter of Credit Lines — As of June 30, 2022, we had utilized $767 million of other uncommitted letter of credit lines with terms maturing through June 2023.

Debt Borrowings and Repayments

Commercial Paper Program — During the six months ended June 30, 2022, we made cash repayments of $4.1 billion, which were partially offset by $3.4 billion of cash borrowings (net of related discount on issuance).

Term Loan — In May 2022, we borrowed $1.0 billion under our Term Loan to be used for general corporate purposes.

Senior Notes — In May 2022, WMI issued $1.0 billion of 4.15% senior notes due April 15, 2032, the net proceeds of which were $992 million. We used the net proceeds to redeem our $500 million of 2.9% senior notes due September 2022 in advance of their scheduled maturity, to repay a portion of outstanding borrowings under our commercial paper program and for general corporate purposes.

Financing Leases and Other — The increase in our financing leases and other debt obligations during the six months ended June 30, 2022 is primarily related to our new federal low-income housing investment discussed in Note 4, which increased our debt obligations by $183 million. The increase in our debt obligations was partially offset by $42 million of cash repayments of debt at maturity.
