1.BASIS OF PRESENTATION AND SUMMARY

The accompanying condensed consolidated financial statements relate to Waste Connections, Inc. and its subsidiaries (the “Company”) for the three and nine month periods ended September 30, 2022 and 2021. In the opinion of management, the accompanying balance sheets and related interim statements of net income, comprehensive income, cash flows and equity include all adjustments, consisting only of normal recurring items, necessary for their fair statement in conformity with U.S. generally accepted accounting principles (“GAAP”). Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Examples include accounting for landfills, self-insurance accruals, income taxes, allocation of acquisition purchase price, contingent consideration accruals and asset impairments. An additional area that involves estimation is when the Company estimates the amount of potential exposure it may have with respect to litigation, claims and assessments in accordance with the accounting guidance on contingencies. Actual results for all estimates could differ materially from the estimates and assumptions that the Company uses in the preparation of its condensed consolidated financial statements.

Interim results are not necessarily indicative of results for a full year. These interim financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

2.REPORTING CURRENCY

The functional currency of the Company, as the parent corporate entity, and its operating subsidiaries in the United States, is the U.S. dollar. The functional currency of the Company’s Canadian operations is the Canadian dollar. The reporting currency of the Company is the U.S. dollar. The Company’s consolidated Canadian dollar financial position is translated to U.S. dollars by applying the foreign currency exchange rate in effect at the consolidated balance sheet date. The Company’s consolidated Canadian dollar results of operations and cash flows are translated to U.S. dollars by applying the average foreign currency exchange rate in effect during the reporting period. The resulting translation adjustments are included in other comprehensive income or loss. Gains and losses from foreign currency transactions are included in earnings for the period.

3.NEW ACCOUNTING STANDARDS

Accounting Standards Pending Adoption

Reference Rate Reform – Facilitation of the Effects of Reference Rate Reform on Financial Reporting.  In March 2020, the Financial Accounting Standards Board (“FASB”) issued guidance to provide temporary optional expedients and exceptions to the guidance in GAAP on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (“SOFR”).  One-week and two-month U.S. dollar LIBOR settings as well as all non-U.S. dollar LIBOR settings stopped being published on December 31, 2021, while the remaining U.S. dollar LIBOR settings will be discontinued on June 30, 2023.  Under the new guidance, entities can elect not to apply certain modification accounting requirements to contracts affected by reference rate reform, if certain criteria are met.  An entity that makes this election would not have to remeasure the contracts at the modification date or reassess a previous accounting determination.  Under the guidance, entities can also elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met.

The guidance was effective upon issuance.  The guidance on contract modifications was applied prospectively from March 12, 2020.  The guidance on hedging is applied to eligible hedging relationships existing as of the beginning of the

7

(Unaudited)

(DOLLAR AMOUNTS IN THOUSANDS OF U.S. DOLLARS, EXCEPT PER SHARE, PER TON AND PER GALLON AMOUNTS)

interim period that includes the effective date and to new eligible hedging relationships entered into after the beginning of that interim period.  The relief is temporary and generally cannot be applied to contract modifications that occur after December 31, 2022 or hedging relationships entered into or evaluated after that date.  However, certain optional expedients can be applied to hedging relationships evaluated in periods after December 31, 2022.  

The Company determined that the new guidance will not have a material effect on its consolidated financial statements.  The Company had a combined $1,251,000 of U.S. LIBOR based loans as of September 30, 2022. The Company estimates that if the reference rate for these loans had transitioned from LIBOR to SOFR as of September 30, 2022, the impact to annual interest expense would have been immaterial.  

In October 2022, the Company adopted the applicable practical expedients of the standard when it converted the option of a LIBOR interest rate in its Credit Agreement to a SOFR interest rate and correspondingly amended its five interest rate swap agreements that are specifically designated to the amended Credit Agreement.  As permitted by the practical expedients in the standard, the Company maintained cash flow hedge accounting for its interest rate swap agreements as the conversion of the LIBOR interest rate to SOFR was the only modification to the interest rate swap agreements.  See Notes 10 and 19 for further details on the amendment to the Credit Agreement.

4.REVENUE

The Company’s operations primarily consist of providing non-hazardous waste collection, transfer, disposal and recycling services, non-hazardous oil and natural gas exploration and production (“E&P”) waste treatment, recovery and disposal services and intermodal services. The following table disaggregates the Company’s revenues by service line for the periods indicated:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2022		2021		2022		2021
Commercial	$	564,592	$	465,246	$	1,602,793	$	1,335,686

Total	$	1,879,868	$	1,597,168	$	5,342,558	$	4,527,042

The factors that impact the timing and amount of revenue recognized for each service line may vary based on the nature of the service performed. Generally, the Company recognizes revenue at the time it performs a service. In the event that the Company bills for services in advance of performance, it recognizes deferred revenue for the amount billed and subsequently recognizes revenue at the time the service is provided.  Substantially all of the deferred revenue recorded as of June 30, 2022 was recognized as revenue during the three months ended September 30, 2022 when the service was performed.

See Note 11 for additional information regarding revenue by reportable segment.

Contract Acquisition Costs

The incremental direct costs of obtaining a contract, which consist of sales incentives, are recognized as Other assets in the Company’s Condensed Consolidated Balance Sheet, and are amortized to Selling, general and administrative expense over the estimated life of the relevant customer relationship, which ranges from one to five years. The Company recognizes the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company would have recognized is one year or less.  The Company had $19,627 and $18,954 of deferred sales incentives at September 30, 2022 and December 31, 2021, respectively.

5.ACCOUNTS RECEIVABLE

Accounts receivable are recorded when billed or accrued and represent claims against third parties that will be settled in cash. The carrying value of the Company’s receivables, net of the allowance for credit losses, represents their estimated net realizable value.

The allowance for credit losses is based on management’s assessment of the collectability of assets pooled together with similar risk characteristics.  The Company monitors the collectability of its trade receivables as one overall pool due to all trade receivables having similar risk characteristics.  The Company estimates its allowance for credit losses based on historical collection trends, the age of outstanding receivables, geographical location of the customer, existing economic conditions and reasonable forecasts. If events or changes in circumstances indicate that specific receivable balances may be impaired, further consideration is given to the collectability of those balances and the allowance is adjusted accordingly. Past-due receivable balances are written off when the Company’s internal collection efforts have been unsuccessful in collecting the amount due.

The following is a rollforward of the Company’s allowance for credit losses for the periods indicated:

	Nine Months Ended September 30,
	2022		2021
Beginning balance	$	18,480	$	19,380

Ending balance	$	20,512	$	20,306

6.LANDFILL ACCOUNTING

At September 30, 2022, the Company’s landfills consisted of 86 owned landfills, five landfills operated under life-of-site operating agreements and five landfills operated under limited-term operating agreements. The Company’s landfills had site costs with a net book value of $2,949,498 at September 30, 2022. For the Company’s landfills operated under limited-term operating agreements and life-of-site operating agreements, the owner of the property (generally a municipality) usually owns the permit and the Company operates the landfill for a contracted term. Where the contracted term is not the life of the landfill, the property owner is generally responsible for final capping, closure and post-closure obligations. The Company is responsible for all final capping, closure and post-closure liabilities at the landfills it operates under life-of-site operating agreements.

The Company’s internal and third-party engineers perform surveys at least annually to estimate the remaining disposal capacity at its landfills. Many of the Company’s existing landfills have the potential for expanded disposal capacity beyond the amount currently permitted. The Company’s landfill depletion rates are based on the remaining disposal capacity, considering both permitted and probable expansion airspace, at the landfills it owns and landfills it operates, but does not own, under life-of-site agreements. The Company’s landfill depletion rate is based on the term of the operating agreement at its operated landfill that has capitalized expenditures. Expansion airspace consists of additional disposal capacity being pursued through means of an expansion that has not yet been permitted. Expansion airspace that meets certain criteria is included in the estimate of total landfill airspace.

Based on remaining permitted capacity as of September 30, 2022, and projected annual disposal volumes, the average remaining landfill life for the Company’s owned landfills and landfills operated under life-of-site operating agreements is estimated to be approximately 30 years. As of September 30, 2022, the Company is seeking to expand permitted capacity at eight of its owned landfills and two landfills that it operates under life-of-site operating agreements, and considers the achievement of these expansions to be probable. Although the Company cannot be certain that all future expansions will be permitted as designed, the average remaining life, when considering remaining permitted capacity, probable expansion capacity and projected annual disposal volume, of the Company’s owned landfills and landfills operated under life-of-site operating agreements is approximately 34 years.  The estimated remaining lives of the Company’s owned landfills and landfills operated under life-of-site operating agreements range from 1 to 330 years, with approximately 90% of the projected annual disposal volume from landfills with remaining lives of less than 70 years.

During the nine months ended September 30, 2022 and 2021, the Company expensed $172,118 and $160,470, respectively, or an average of $4.88 and $4.56 per ton consumed, respectively, related to landfill depletion at owned landfills and landfills operated under life-of-site agreements.

The Company reserves for estimated final capping, closure and post-closure maintenance obligations at the landfills it owns and landfills it operates under life-of-site operating agreements. The Company calculates the net present value of its final capping, closure and post-closure liabilities by estimating the total obligation in current dollars, inflating the obligation based upon the expected date of the expenditure and discounting the inflated total to its present value using a credit-adjusted risk-free rate. Any changes in expectations that result in an upward revision to the estimated undiscounted cash flows are treated as a new liability and are inflated and discounted at rates reflecting market conditions. Any changes in expectations that result in a downward revision (or no revision) to the estimated undiscounted cash flows result in a liability that is inflated and discounted at rates reflecting the market conditions at the time the cash flows were originally estimated. This policy results in the Company’s final capping, closure and post-closure liabilities being recorded in “layers.”  The Company’s discount rate assumption for purposes of computing 2022 and 2021 “layers” for final capping, closure and post-closure obligations was 3.25% for both years, which reflects the Company’s long-term credit adjusted risk free rate as of the end of 2021 and 2020. The Company’s long-term inflation rate assumption is 2.25% for the years ending December 31, 2022 and 2021. The resulting final capping, closure and post-closure obligations are recorded on the Condensed Consolidated Balance Sheet along with an offsetting addition to site costs which is amortized to depletion expense as the remaining landfill airspace is consumed. Interest is accreted on the recorded liability using the corresponding discount rate. During the nine months ended September 30, 2022 and 2021, the Company expensed $12,008 and $10,783, respectively, or an average of $0.34 and $0.31 per ton consumed, respectively, related to final capping, closure and post-closure accretion expense.

9.LEASES

The Company rents certain equipment and facilities under short-term agreements, non-cancelable operating lease agreements and finance leases.  The Company determines if an arrangement is or contains a lease at contract inception. The Company recognizes a right-of-use (“ROU”) asset and a lease liability at the lease commencement date.  The lease liability is initially measured at the present value of the unpaid lease payments at the lease commencement date.

Key estimates and judgments include how the Company determines (1) the discount rate it uses to discount the unpaid lease payments to present value, (2) lease term and (3) lease payments.

The lease guidance requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. Generally, the Company cannot determine the interest rate implicit in the lease because it does not have access to the lessor’s estimated residual value or the amount of the lessor’s deferred initial direct costs.  Therefore, the Company generally uses its incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms.

The lease term for the Company’s leases includes the noncancelable period of the lease, plus any additional periods covered by either a Company option to extend (or not to terminate) the lease that the Company is reasonably certain to exercise, or an option to extend (or not to terminate) the lease controlled by the lessor.

Lease payments included in the measurement of the lease liability comprise fixed payments or variable lease payments.  The variable lease payments take into account annual changes in the consumer price index and common area maintenance charges, if known.

ROU assets for operating and finance leases are periodically reviewed for impairment losses. The Company uses the long-lived asset impairment guidance in ASC Subtopic 360-10, Property, Plant, and Equipment – Overall, to determine whether an ROU asset is impaired, and if so, the amount of the impairment loss to recognize.  The Company did not recognize an impairment charge for any of its ROU assets during the nine months ended September 30, 2022 and 2021.

The Company monitors for events or changes in circumstances that require a reassessment of one of its leases. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the corresponding ROU asset.  The Company did not recognize any significant remeasurements during the nine months ended September 30, 2022 and 2021.

The Company has elected not to recognize ROU assets and lease liabilities for short-term leases that have a lease term of 12 months or less. The Company has elected to apply the short-term lease recognition and measurement exemption allowed for in the lease accounting standard.  The Company recognizes the lease payments associated with its short-term leases as an expense on a straight-line basis over the lease term.

In addition to the $42,708 of letters of credit at September 30, 2022 issued and outstanding under the Credit Agreement, the Company has issued and outstanding letters of credit totaling $84,742 under a facility other than the Credit Agreement.

Senior Notes

On March 9, 2022, the Company completed an underwritten public offering of $500,000 aggregate principal amount of 3.20% Senior Notes due 2032 (the “New 2032 Senior Notes”). The Company issued the New 2032 Senior Notes under the Indenture, dated as of November 16, 2018 (the “Base Indenture”), by and between the Company and U.S. Bank Trust Company, National Association, as successor in interest to U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by the Sixth Supplemental Indenture, dated as of March 9, 2022 (the “Sixth Supplemental Indenture”).  The New 2032 Senior Notes will mature on June 1, 2032.

The Company may, prior to March 1, 2032 (three months before the maturity date) (the “New 2032 Senior Notes Par Call Date”), redeem some or all of the New 2032 Senior Notes, at any time and from time to time, at a redemption price equal to the greater of 100% of the principal amount of the New 2032 Senior Notes redeemed, or the sum of the present values of the remaining scheduled payments of principal and interest on the New 2032 Senior Notes redeemed discounted to the redemption date (assuming the New 2032 Senior Notes matured on the New 2032 Senior Notes Par Call Date), plus, in either case, accrued and unpaid interest thereon to the redemption date. Commencing on March 1, 2032 (three months before the maturity date), the Company may redeem some or all of the New 2032 Senior Notes, at any time and from time to time, at a redemption price equal to the principal amount of the New 2032 Senior Notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

On August 18, 2022, the Company completed an underwritten public offering of $750,000 aggregate principal amount of 4.20% Senior Notes due 2033 (the “2033 Senior Notes” and, together with the New 2032 Senior Notes, the “Senior Notes”). The Company issued the 2033 Senior Notes under the Base Indenture, as supplemented by the Seventh Supplemental Indenture, dated as of August 18, 2022 (the “Seventh Supplemental Indenture” and the Base Indenture as supplemented by the Sixth Supplemental Indenture and the Seventh Supplemental Indenture, the “Indenture”).  The 2033 Senior Notes will mature on January 15, 2033.

The Company may, prior to October 15, 2032 (three months before the maturity date) (the “2033 Senior Notes Par Call Date”), redeem some or all of the 2033 Senior Notes, at any time and from time to time, at a redemption price equal to the greater of 100% of the principal amount of the 2033 Senior Notes redeemed, or the sum of the present values of the remaining scheduled payments of principal and interest on the 2033 Senior Notes redeemed discounted to the redemption date (assuming the 2033 Senior Notes matured on the 2033 Senior Notes Par Call Date), plus, in either case, accrued and unpaid interest thereon to the redemption date. Commencing on October 15, 2032 (three months before the maturity date), the Company may redeem some or all of the 2033 Senior Notes, at any time and from time to time, at a redemption price equal to the principal amount of the 2033 Senior Notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

The Company will pay interest on the Senior Notes semi-annually in arrears. The Senior Notes are the Company’s senior unsecured obligations, ranking equally in right of payment with its other existing and future unsubordinated debt and senior to any of its future subordinated debt. The Senior Notes are not guaranteed by any of the Company’s subsidiaries.

Under certain circumstances, the Company may become obligated to pay additional amounts (the “Additional Amounts”) with respect to the Senior Notes to ensure that the net amounts received by each holder of the Senior Notes will not be less than the amount such holder would have received if withholding taxes or deductions were not incurred on

17

(Unaudited)

(DOLLAR AMOUNTS IN THOUSANDS OF U.S. DOLLARS, EXCEPT PER SHARE, PER TON AND PER GALLON AMOUNTS)

a payment under or with respect to the Senior Notes. If such payment of Additional Amounts are a result of a change in the laws or regulations, including a change in any official position, the introduction of an official position or a holding by a court of competent jurisdiction, of any jurisdiction from or through which payment is made by or on behalf of the Senior Notes having power to tax, and the Company cannot avoid such payments of Additional Amounts through reasonable measures, then the Company may redeem the Senior Notes then outstanding at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date).

If the Company experiences certain kinds of changes of control, each holder of the Senior Notes may require the Company to repurchase all or a portion of the Senior Notes for cash at a price equal to 101% of the aggregate principal amount of such Senior Notes, plus any accrued and unpaid interest, if any, to, but excluding the purchase date.

The covenants in the Indenture include limitations on liens, sale-leaseback transactions and mergers and sales of all or substantially all of the Company’s assets. The Indenture also includes customary events of default with respect to the Senior Notes. As of September 30, 2022, the Company was in compliance with all applicable covenants in the Indenture.

Upon an event of default, the principal of and accrued and unpaid interest on all the Senior Notes may be declared to be due and payable by the Trustee or the holders of not less than 25% in principal amount of the outstanding Senior Notes. Upon such a declaration, such principal and accrued interest on all of the Senior Notes will be due and payable immediately. In the case of an event of default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding Senior Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holder of the Senior Notes. Under certain circumstances, the holders of a majority in principal amount of the outstanding Senior Notes may rescind any such acceleration with respect to the Senior Notes and its consequences.

Term Loan Agreement

On October 31, 2022 (the “Effective Date”), the Company, as borrower, Bank of America, N.A., as administrative agent, and the other lenders from time to time party thereto (the “New TL Lenders”) entered into that certain Term Loan Agreement (as amended, restated, supplemented or otherwise modified from time to time, the “Term Loan Agreement”), pursuant to which the New TL Lenders made loans to the Company in an aggregate stated principal amount of $800,000.  The Term Loan Agreement permits the proceeds of borrowings thereunder to be used for (i) refinancing outstanding indebtedness, (ii) financing permitted acquisitions and financing dividends or other permitted equity distributions, (iii) capital expenditures, working capital, payment of certain transaction fees, costs and expenses and (iv) any other lawful corporate purposes.  The Company intends to use substantially all of the proceeds of borrowings under the Term Loan Agreement to repay revolving borrowings outstanding under its Credit Agreement (as defined below) following the implementation of the Term Loan Agreement

Pursuant to the terms and conditions of the Term Loan Agreement, the New TL Lenders committed to provide the term loan as set forth above, which term loan was fully drawn as of the Effective Date.  Amounts borrowed under the Term Loan Agreement and repaid or prepaid may not be reborrowed.  The Term Loan Agreement has a scheduled maturity date of July 30, 2026.

Interest accrues on the term loan by reference to SOFR for specified interest periods (“Term SOFR”) (including for all Term SOFR loans, a credit spread adjustment of 0.10% for all applicable interest periods) or a base rate, at the Company’s option, plus an applicable margin.  The applicable margin used in connection with calculating interest rates and fees is based on the debt rating of the Company’s public non-credit-enhanced, senior unsecured long-term debt.  The

18

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(DOLLAR AMOUNTS IN THOUSANDS OF U.S. DOLLARS, EXCEPT PER SHARE, PER TON AND PER GALLON AMOUNTS)

applicable margin for Term SOFR loans ranges from 0.750% to 1.250% per annum, and the applicable margin for base rate loans ranges from 0.00% to 0.250% per annum.

The Term Loan Agreement contains customary benchmark replacement mechanics in connection with certain benchmark transition events, as well as customary mechanics with respect to the unavailability of a tenor of a then-current benchmark rate. The borrowings under the Term Loan Agreement are unsecured and there are no subsidiary guarantors under the Term Loan Agreement.  

The Term Loan Agreement contains customary representations, warranties, covenants and events of default, including, among others, a change of control event of default and limitations on the incurrence of indebtedness and liens, new lines of business, mergers, transactions with affiliates and burdensome agreements. During the continuance of an event of default, the New TL Lenders may take a number of actions, including, among others, declaring the entire amount then outstanding under the Term Loan Agreement and related loan documents to be due and payable.

The Term Loan Agreement includes a financial covenant limiting, as of the last day of each fiscal quarter, the ratio of (i) Consolidated Total Funded Debt (as defined in the Term Loan Agreement) outstanding as of such date to (b) Consolidated EBITDA (as defined in the Term Loan Agreement), measured for the preceding 12 months, to not more than 3.75 to 1.00 (or 4.25 to 1.00 during material acquisition periods, subject to certain limitations).

Amendment No. 1 to Second Amended and Restated Revolving Credit and Term Loan Agreement

The Company is party to that certain Second Amended and Restated Revolving Credit and Term Loan Agreement, dated as of July 30, 2021 (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”), by and among the Company, as borrower, Bank of America, N.A., acting through its Canada Branch, as the global agent, the swing line lender and an l/c issuer, Bank of America, N.A., as the U.S. agent and an l/c issuer, and the lenders and any other financial institutions from time to time party thereto.

On the Effective Date, the Company entered into an amendment to the Credit Agreement (the “First Amendment”), which among other things, (i) amended certain definitions and other provisions to replace the LIBOR-based benchmark rates for certain U.S. dollar-denominated loans and other extensions of credit under the Credit Agreement with Term SOFR, and (ii) made certain changes conforming to the Term Loan Agreement.  The rates of interest payable by the Company per annum on its outstanding revolving loans immediately prior to the Effective Date did not materially change immediately after the Effective Date as a result of the replacement of LIBOR-based benchmark rates with Term SOFR.  In addition, because the replacement of LIBOR-based benchmark rates with Term SOFR was implemented through the First Amendment and not as a result of the hardwired benchmark replacement setting provisions of the Credit Agreement, the credit spread adjustment applicable to Term SOFR loans is a flat 0.10% per annum across all applicable interest periods instead of a varying credit spread adjustment across the same interest periods ranging from 0.11448% to 0.42826%.

11.SEGMENT REPORTING

The Company’s revenues are generated from the collection, transfer, recycling and disposal of non-hazardous solid waste and the treatment, recovery and disposal of non-hazardous E&P waste. No single contract or customer accounted for more than 10% of the Company’s total revenues at the consolidated or reportable segment level during the periods presented.

The Company manages its operations through the following five geographic solid waste operating segments: Eastern, Southern, Western, Central and Canada.  The Company’s five geographic solid waste operating segments comprise its

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(DOLLAR AMOUNTS IN THOUSANDS OF U.S. DOLLARS, EXCEPT PER SHARE, PER TON AND PER GALLON AMOUNTS)

reportable segments.  Each operating segment is responsible for managing several vertically integrated operations, which are comprised of districts.  

The Company’s Chief Operating Decision Maker evaluates operating segment profitability and determines resource allocations based on several factors, of which the primary financial measure is segment EBITDA. The Company defines segment EBITDA as earnings before interest, taxes, depreciation, amortization, impairments and other operating items, and other income (expense). Segment EBITDA is not a measure of operating income, operating performance or liquidity under GAAP and may not be comparable to similarly titled measures reported by other companies. The Company’s management uses segment EBITDA in the evaluation of segment operating performance as it is a profit measure that is generally within the control of the operating segments. A reconciliation of segment EBITDA to Income before income tax provision is included at the end of this Note 11.

Summarized financial information concerning the Company’s reportable segments for the three and nine months ended September 30, 2022 and 2021, is shown in the following tables:

(a) The majority of Corporate expenses are allocated to the five operating segments.  Direct acquisition expenses, expenses associated with common shares held in the deferred compensation plan exchanged for other investment options and share-based compensation expenses associated with Progressive Waste share-based grants outstanding at June 1, 2016 that were continued by the Company are not allocated to the five operating segments and comprise the net EBITDA of the Company’s Corporate segment for the periods presented.

(b) Intercompany revenues reflect each segment’s total intercompany sales, including intercompany sales within a segment and between segments. Transactions within and between segments are generally made on a basis intended to reflect the market value of the service.

All of the Company’s derivatives have been designated as cash flow hedges; therefore, the gain or loss on the derivatives will be recognized in accumulated other comprehensive income (loss) (“AOCIL”) and reclassified into earnings in the same period during which the hedged transaction affects earnings and is presented in the same income statement line item as the earnings effect of the hedged item.  The Company classifies cash inflows and outflows from derivatives within operating activities on the Condensed Consolidated Statements of Cash Flows.

One of the Company’s objectives for utilizing derivative instruments is to reduce its exposure to fluctuations in cash flows due to changes in the variable interest rates of certain borrowings under the Credit Agreement. The Company’s strategy to achieve that objective involves entering into interest rate swaps. The interest rate swaps outstanding at September 30, 2022 were specifically designated to the Credit Agreement and accounted for as cash flow hedges.

____________________

(a)In accordance with the derivatives and hedging guidance, the changes in fair values of interest rate swaps have been recorded in equity as a component of AOCIL. As the critical terms of the interest rate swaps match the underlying debt being hedged, all unrealized changes in fair value are recorded in AOCIL.

(b)Amounts reclassified from AOCIL into earnings related to realized gains and losses on interest rate swaps are recognized when interest payments or receipts occur related to the swap contracts, which correspond to when interest payments are made on the Company’s hedged debt.

See Note 16 for further discussion on the impact of the Company’s hedge accounting to its consolidated comprehensive income (loss) and AOCIL.  

13.FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company’s financial instruments consist primarily of cash and equivalents, trade receivables, restricted cash and investments, trade payables, debt instruments, contingent consideration obligations and interest rate swaps. As of September 30, 2022 and December 31, 2021, the carrying values of cash and equivalents, trade receivables, restricted cash and investments, trade payables and contingent consideration are considered to be representative of their respective fair values. The carrying values of the Company’s debt instruments, excluding certain notes as listed in the table below, approximate their fair values as of September 30, 2022 and December 31, 2021, based on current borrowing rates, current remaining average life to maturity and borrower credit quality for similar types of borrowing arrangements, and are classified as Level 2 within the fair value hierarchy. The carrying values and fair values of the Company’s debt instruments where the carrying values do not approximate their fair values as of September 30, 2022 and December 31, 2021, are as follows:

	Carrying Value at				Fair Value (a) at
	September 30,		December 31,		September 30,		December 31,
	2022		2021		2022		2021

15.FAIR VALUE MEASUREMENTS

The Company uses a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis in periods subsequent to their initial measurement. These tiers include:  Level 1, defined as quoted market prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, model-based valuation techniques for which all significant assumptions are observable in the market, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3, defined as unobservable inputs that are not corroborated by market data.

The Company’s financial assets and liabilities recorded at fair value on a recurring basis include derivative instruments and restricted cash and investments. At September 30, 2022 and December 31, 2021, the Company’s derivative instruments included pay-fixed, receive-variable interest rate swaps. The Company’s interest rate swaps are recorded at their estimated fair values based on quotes received from financial institutions that trade these contracts. The Company verifies the reasonableness of these quotes using similar quotes from another financial institution as of each date for which financial statements are prepared. For the Company’s interest rate swaps, the Company also considers the Company’s creditworthiness in its determination of the fair value measurement of these instruments in a net liability position and the counterparties’ creditworthiness in its determination of the fair value measurement of these instruments in a net asset position. The Company’s restricted cash is valued at quoted market prices in active markets for identical assets, which the Company receives from the financial institutions that hold such investments on its behalf. The Company’s restricted cash measured at fair value is invested primarily in money market accounts, bank time deposits and U.S. government and agency securities. The Company’s restricted investments are valued at quoted market prices in active markets for similar assets, which the Company receives from the financial institutions that hold such investments on its behalf. The Company’s restricted investments measured at fair value are invested primarily in money market accounts, bank time deposits, U.S. government and agency securities and Canadian bankers’ acceptance notes.

WASTE CONNECTIONS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(DOLLAR AMOUNTS IN THOUSANDS OF U.S. DOLLARS, EXCEPT PER SHARE, PER TON AND PER GALLON AMOUNTS)

each payroll date in amounts equal to or greater than one percent (1%) but not in excess of ten percent (10%) of eligible compensation in order to purchase the Company’s common shares under certain terms and subject to certain restrictions set forth in the ESPP. The exercise price is equal to 95% of the closing price of the Company’s common shares on the last day of the relevant offering period, provided, however, that such exercise price will not be less than 85% of the volume weighted average price of the Company’s common shares as reflected on the Toronto Stock Exchange (the “TSX”) over the final five trading days of such offering period. The maximum number of shares that may be issued under the ESPP is 1,000,000.  Under the ESPP, employees purchased 26,582 of the Company’s common shares for $3,271 during the nine months ended September 30, 2022.

Normal Course Issuer Bid

On July 26, 2022, the Board of Directors of the Company approved, subject to receipt of regulatory approvals, the annual renewal of the Company’s normal course issuer bid (the “NCIB”) to purchase up to 12,859,066 of the Company’s common shares during the period of August 10, 2022 to August 9, 2023 or until such earlier time as the NCIB is completed or terminated at the option of the Company. The renewal followed the conclusion of the Company’s NCIB that expired August 9, 2022. The Company received TSX approval for its annual renewal of the NCIB on August 8, 2022.  Under the NCIB, the Company may make share repurchases only in the open market, including on the New York Stock Exchange (the “NYSE”), the TSX, and/or alternative Canadian trading systems, at the prevailing market price at the time of the transaction.

In accordance with TSX rules, any daily repurchases made through the TSX and alternative Canadian trading systems is limited to a maximum of 85,956 common shares, which represents 25% of the average daily trading volume on the TSX of 343,825 common shares for the period from February 1, 2022 to July 31, 2022. The TSX rules also allow the Company to purchase, once a week, a block of common shares not owned by any insiders, which may exceed such daily limit. The maximum number of shares that can be purchased per day on the NYSE will be 25% of the average daily trading volume for the four calendar weeks preceding the date of purchase, subject to certain exceptions for block purchases.

The timing and amounts of any repurchases pursuant to the NCIB will depend on many factors, including the Company’s capital structure, the market price of the common shares and overall market conditions. All common shares purchased under the NCIB shall be immediately cancelled following their repurchase.

For the nine months ended September 30, 2022, the Company repurchased 3,388,155 common shares pursuant to the NCIB in effect during that period at an aggregate cost of $424,999.  During the nine months ended September 30, 2021, the Company repurchased 2,745,990 common shares pursuant to the NCIB in effect during that period at an aggregate cost of $305,640.  As of September 30, 2022, the remaining maximum number of shares available for repurchase under the current NCIB was 12,859,066.

Cash Dividend

In October 2021, the Company announced that its Board of Directors increased its regular quarterly cash dividend by $0.025, from $0.205 to $0.23 per Company common share. Cash dividends of $177,710 and $160,754 were paid during the nine months ended September 30, 2022 and 2021, respectively.

18.COMMITMENTS AND CONTINGENCIES

In the normal course of its business and as a result of the extensive governmental regulation of the solid waste and E&P waste industries, the Company is subject to various judicial and administrative proceedings involving Canadian regulatory authorities as well as U.S. federal, state and local agencies. In these proceedings, an agency may subpoena the

Company for records, or seek to impose fines on the Company or revoke or deny renewal of an authorization held by the Company, including an operating permit. From time to time, the Company may also be subject to actions brought by special interest or other groups, adjacent landowners or residents in connection with the permitting and licensing of landfills, transfer stations, and E&P waste treatment, recovery and disposal operations, or alleging environmental damage or violations of the permits and licenses pursuant to which the Company operates. The Company uses $1,000 as a threshold (up from the previously required threshold of $300) for disclosing environmental matters involving potential monetary sanctions.

In addition, the Company is a party to various claims and suits pending for alleged damages to persons and property, alleged violations of certain laws and alleged liabilities arising out of matters occurring during the normal operation of the Company’s business. Except as noted in the matters described below, as of September 30, 2022, there is no current proceeding or litigation involving the Company or its property that the Company believes could have a material adverse effect on its business, financial condition, results of operations or cash flows.

A. Chiquita Canyon, LLC Lawsuit Against Los Angeles County

In October 2004, the Company’s subsidiary, Chiquita Canyon, LLC (“CCL”), then under prior ownership, filed an application (the “Application”) with the County of Los Angeles (the “County”) Department of Regional Planning (“DRP”) for a conditional use permit (the “CUP”) to authorize the continued operation and expansion of the Chiquita Canyon Landfill (the “Landfill”). The Landfill has operated since 1972, and as a regional landfill, accepted approximately two and a half million tons of materials for disposal and beneficial use in 2021.  The Application requested expansion of the existing waste footprint on CCL’s contiguous property, an increase in maximum elevation, creation of a new entrance and new support facilities, construction of a facility for the County or another third-party operator to host household hazardous waste collection events, designation of an area for mixed organics/composting, and other modifications.

After many years of reviews and delays, upon the recommendation of County staff, the County’s Regional Planning Commission (the “Commission”) approved the Application on April 19, 2017, but imposed operating conditions, fees and exactions that substantially reduce the historical landfill operations and represent a large increase in aggregate taxes and fees. CCL objected to many of the requirements imposed by the Commission.  Current estimates for new costs imposed on CCL under the CUP are in excess of $300,000.

CCL appealed the Commission’s decision to the County Board of Supervisors, but the appeal was not successful.  At a subsequent hearing, on July 25, 2017, the Board of Supervisors approved the CUP.  On October 20, 2017, CCL filed in the Superior Court of California, County of Los Angeles a verified petition for writ of mandate and complaint against the County and the County Board of Supervisors captioned Chiquita Canyon, LLC v. County of Los Angeles, No. BS171262 (Los Angeles Co. Super Ct.) (the “Complaint”).  The Complaint challenges the terms of the CUP in 13 counts generally alleging that the County violated multiple California and federal statutes and California and federal constitutional protections. CCL seeks the following relief: (a) an injunction and writ of mandate against certain of the CUP’s operational restrictions, taxes and fees, (b) a declaration that the challenged conditions are unconstitutional and in violation of state and federal statutes, (c) reimbursement for any such illegal fees paid under protest, (d) damages, (e) an award of just compensation for a taking, (f) attorney fees, and (g) all other appropriate legal and equitable relief.

Following extensive litigation in 2018 and 2019 on the permissible scope of CCL’s challenge, full briefing occurred, and oral argument was held on June 22, 2020 on six of CCL’s causes of action. The Superior Court issued its decision on July 2, 2020, granting CCL’s petition for writ of mandate in part and denying it in part. CCL prevailed with respect to 12 of the challenged conditions, many of which imposed new fees and exactions on the Landfill.  On October 11, 2022, CCL

and the County entered into a settlement agreement that requires Chiquita to file a CUP modification application with the County embodying the terms of the settlement agreement.  If the CUP modification application is approved by the County and certain other contingencies are satisfied, Chiquita will dismiss this lawsuit.  However, at this point, the Company is not able to determine the likelihood of any outcome in this matter.

B. December 11, 2017 Notice of Violation Regarding Certain CUP Conditions.

The County, through its DRP, issued a Notice of Violation, dated December 11, 2017 (the “NOV”), alleging that CCL violated certain conditions of the CUP, including Condition 79(B)(6) of the CUP by failing to pay an $11,600 Bridge & Thoroughfare Fee (“B&T Fee”) that was purportedly due on July 25, 2017.  The alleged B&T fee was ostensibly to fund the construction of transportation infrastructure in the area of the Landfill.  At the time the NOV was issued, CCL had already contested the legality of the B&T fee in the October 20, 2017 Complaint filed against the County in Los Angeles County Superior Court, described above under paragraph A (the “CUP lawsuit”).

On January 12, 2018, CCL filed an appeal of the alleged violations in the NOV.  Subsequently, CCL filed additional legal arguments and exhibits contesting the NOV.  On March 6, 2018, a DRP employee designated as hearing officer sustained the NOV, including the $11,600 B&T fee, and imposed an administrative penalty in the amount of $83 and a noncompliance fee of $0.75. A written decision memorializing the hearing officer’s findings and order was issued on July 10, 2018.  On April 13, 2018, CCL filed in the Superior Court of California, County of Los Angeles a Petition for Writ of Administrative Mandamus against the County seeking to overturn the decision sustaining the NOV, contending that the NOV and decision are not supported by the facts or law.  On July 17, 2018, the Court granted CCL leave to pay the $11,600 B&T fee and to amend its Complaint in the CUP lawsuit to reflect the payment under protest, allowing the challenge to the B&T fee under the Mitigation Fee Act to proceed in the CUP lawsuit.  CCL paid the B&T fee under protest on August 10, 2018, and also paid on that date the administrative penalty of $83 and a noncompliance fee of $0.75. The Court indicated that the NOV case would be coordinated with the CUP lawsuit.  On October 11, 2022, CCL and the County entered into a settlement agreement, described above under paragraph A.  If the CUP modification application is approved by the County and certain other contingencies are satisfied, Chiquita will dismiss this lawsuit.  However, at this point, the Company is not able to determine the likelihood of any outcome in this matter.

OVERVIEW OF OUR BUSINESS

We are an integrated solid waste services company that provides non-hazardous waste collection, transfer and disposal services, along with resource recovery primarily through recycling and renewable fuels generation, in mostly exclusive and secondary markets across 43 states in the U.S. and six provinces in Canada. Waste Connections also provides non-hazardous oil and natural gas exploration and production (“E&P”) waste treatment, recovery and disposal services in several basins across the U.S., as well as intermodal services for the movement of cargo and solid waste containers in the Pacific Northwest.

Environmental, organizational and financial sustainability initiatives have been key components of our success since we were founded in 1997.  We remain committed to growing and expanding these efforts as our industry and technology continue to evolve. To that end, in 2020, we introduced long-term, aspirational ESG targets and committed over $500 million for investments to meet or exceed such sustainability targets. These investments primarily focus on reducing emissions, increasing resource recovery of both recyclable commodities and clean energy fuels, reducing reliance on off-site disposal for landfill leachate, further improving safety through reduced incidents and enhancing employee engagement through improved voluntary turnover and Servant Leadership scores.  Our 2022 Sustainability Report provides progress updates on its targets and investments towards their achievement. This report can be found at www.wasteconnections.com/sustainability but does not constitute a part of, and is not incorporated by reference into, this Quarterly Report on Form 10-Q.

We generally seek to avoid highly competitive, large urban markets and instead target markets where we can attain high market share either through exclusive contracts, vertical integration or asset positioning. In markets where waste collection services are provided under exclusive arrangements, or where waste disposal is municipally owned or funded or available at multiple municipal sources, we believe that controlling the waste stream by providing collection services under exclusive arrangements is often more important to our growth and profitability than owning or operating landfills. We also target niche markets, like non-hazardous E&P waste treatment, recovery and disposal services.

The solid waste industry is local and highly competitive in nature, requiring substantial labor and capital resources. We compete for collection accounts primarily on the basis of price and, to a lesser extent, the quality of service, and compete for landfill business on the basis of tipping fees, geographic location and quality of operations. The solid waste industry has been consolidating and continues to consolidate as a result of a number of factors, including the increasing costs and complexity associated with waste management operations and regulatory compliance. Many small independent operators and municipalities lack the capital resources, management, operating skills and technical expertise necessary to operate effectively in such an environment. The consolidation trend has caused solid waste companies to operate larger landfills that have complementary collection routes that can use company-owned disposal capacity. Controlling the point of transfer from haulers to landfills has become increasingly important as landfills continue to close and disposal capacity moves farther from the collection markets it serves.

Generally, the most profitable operators within the solid waste industry are those companies that are vertically integrated or enter into long-term collection contracts. A vertically integrated operator will benefit from:  (1) the internalization of waste, which is bringing waste to a company-owned landfill; (2) the ability to charge third-party haulers tipping fees either at landfills or at transfer stations; and (3) the efficiencies gained by being able to aggregate and process waste at a transfer station prior to landfilling.

The demand for our E&P waste services depends on the continued demand for, and production of, oil and natural gas. Crude oil and natural gas prices historically have been volatile. Subject to certain recent developments discussed below, macroeconomic and geopolitical conditions, including a significant decline in oil prices driven by both surplus production and supply, as well as the decrease in demand caused by factors including the COVID-19 pandemic, have resulted in decreased levels of E&P activity and a corresponding decrease in demand for our E&P waste services.  Additionally, across the industry there is uncertainty regarding future demand for oil and related services, as noted by several energy companies, many of whom are customers of our E&P operations.  These companies have written down the values of their oil and gas assets in anticipation of the potential for the decarbonization of their energy product mix given an increased global focus on reducing greenhouse gases and addressing climate change.  Such uncertainty regarding global demand has had a significant impact on the investment and operating plans of our E&P waste customers in the basins where we operate.   If the prices of crude oil and natural gas substantially decline, it could lead to declines in the level of production activity and demand for our E&P waste services, which could result in the recognition of impairment charges on our intangible assets and property and equipment associated with our E&P operations.  Conversely, sustained increases in prices of crude oil as a result of inflationary pressures, the uncertainty associated with the Ukrainian conflict and any related bans on oil sales from Russia or supply chain disruptions as recently experienced could result in increasing levels of production activity and demand for our E&P waste services.

THE COVID-19 PANDEMIC’S IMPACT ON OUR RESULTS OF OPERATIONS

March 11, 2022 marked the two-year anniversary of COVID-19 being declared a global pandemic by the World Health Organization. The related economic disruptions largely associated with closures or restrictions put into effect following the onset of the COVID-19 pandemic in the first quarter of 2020 resulted in declines in solid waste commercial collection, transfer station and landfill volumes, and roll off activity. Throughout the remaining fiscal year 2020 and during 2021, solid waste revenue and reported volumes largely reflected the pace and shape of the closures and subsequent reopening activity, with the timing and magnitude of recovery varying by market.  Most of the impacts to solid waste volumes associated with the pandemic have largely abated, with landfill volumes and roll off pulls returning to pre-pandemic levels.  In certain markets, commercial collection volumes have not returned to pre-pandemic levels.

The COVID-19 pandemic also contributed to a decline in demand for and the value of crude oil, which impacted E&P drilling activity and resulted in lower E&P waste revenue.  In recent quarters, E&P waste revenue has improved sequentially on increased drilling activity in several of the major basins.

Since the onset of the COVID-19 pandemic, protecting the health, welfare and safety of our employees has been our top priority. Recognizing the potential for financial hardship and other challenges, we have looked to provide a safety net for our employees on issues of income and family health. To that end, since the onset of the pandemic through year-end 2021, we incurred over $40 million in incremental COVID-19-related costs, primarily supplemental pay for frontline employees. Through the nine months ended September 30, 2022, we have continued to provide support for our employees and their families, including approximately $10 million in supplemental pay and benefits due to surges in cases related to certain variants of COVID-19.

As a result of the COVID-19 pandemic and subsequent reopening activity, we have also experienced an impact to our operating costs as a result of factors including supply chain disruptions and labor constraints, as demand has recovered and competition has increased.  As a result, we have incurred incremental costs associated with higher wages, increased overtime as a result of higher turnover, and increased reliance on third-party services.  

The impact of the COVID-19 pandemic on our business, results of operations, financial condition and cash flows in future periods will depend largely on future developments, including the duration and spread of the outbreak in the U.S. and Canada, the rate of vaccinations, the severity of COVID-19 variants, the actions to contain such coronavirus variants, and how quickly and to what extent normal economic and operating conditions can resume.

CRITICAL ACCOUNTING ESTIMATES AND ASSUMPTIONS

The preparation of financial statements in conformity with U.S. generally accepted accounting principles, or GAAP, requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses and related disclosures of contingent assets and liabilities in the condensed consolidated financial statements. As described by the SEC, critical accounting estimates and assumptions are those that may be material due to the levels of subjectivity and judgment necessary to account for highly uncertain matters or the susceptibility of such matters to change, and that have a material impact on the financial condition or operating performance of a company. Such critical accounting estimates and assumptions are applicable to our reportable segments. Refer to our most recent Annual Report on Form 10-K for a complete description of our critical accounting estimates and assumptions.

NEW ACCOUNTING PRONOUNCEMENTS

For a description of the new accounting standards that affect us, see Note 3 to our Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Revenues.  Total revenues increased $282.7 million, or 17.7%, to $1.880 billion for the three months ended September 30, 2022, from $1.597 billion for the three months ended September 30, 2021. Total revenues increased $815.5 million, or 18.0%, to $5.343 billion for the nine months ended September 30, 2022, from $4.527 billion for the nine months ended September 30, 2021.

Acquisitions closed during, or subsequent to, the comparable periods increased revenues for the three and nine months ended September 30, 2022 by $154.1 million and $410.6 million, respectively.

Operations that were divested subsequent to September 30, 2021 decreased revenues for the three and nine months ended September 30, 2022 by $3.4 million and $8.6 million, respectively.

During the three months ended September 30, 2022, the net increase in prices charged to our customers at our existing operations was $154.2 million, consisting of $126.3 million of core price increases and surcharges of $27.9 million.  During the nine months ended September 30, 2022, the net increase in prices charged to our customers at our existing operations was $376.9 million, consisting of $315.3 million of core price increases and surcharges of $61.6 million.

During the three months ended September 30, 2022, we recognized volume losses totaling $22.3 million, which were comprised of $14.5 million of declines primarily associated with the nonrenewal of two residential collection contracts subsequent to September 30, 2021 and $7.8 million of declines primarily attributable to decreases in landfill disposal volumes, partially offset by increases in roll off collection. During the nine months ended September 30, 2022, we recognized volume losses totaling $24.3 million, which was comprised of $39.2 million of declines associated with the aforementioned residential collection contracts, partially offset by $14.9 million of increases primarily attributable to commercial and roll off collection.

E&P waste revenues at facilities owned during the three and nine months ended September 30, 2022 and 2021 increased $19.3 million and $55.7 million, respectively, due to increases in overall demand for our E&P waste services resulting from higher demand for crude oil contributing to increases in drilling and production activity levels.

Revenues from sales of recyclable commodities at facilities owned during the three and nine months ended September 30, 2022 and 2021 decreased $19.5 million and $0.3 million, respectively.  Prices for old corrugated cardboard, aluminum, plastics and other paper products increased from the prior period during the six months ended June 30, 2022 before

36

declining during the three months ended September 30, 2022. The impact of lower prices on revenues from sales of recyclable commodities was partially offset by the impact of recognizing certain recyclable commodity sales gross of selling and processing expenses.

A decrease in the average Canadian dollar to U.S. dollar currency exchange rate resulted in a decrease in revenues for the three and nine months ended September 30, 2022 of $7.8 million and $16.2 million, respectively. The average Canadian dollar to U.S. dollar exchange rates on our Canadian revenues during the three months ended September 30, 2022 and 2021 were 0.7660 and 0.7936, respectively. The average Canadian dollar to U.S. dollar exchange rates on our Canadian revenues during the nine months ended September 30, 2022 and 2021 were 0.7792 and 0.7996, respectively.

Other revenues increased $8.1 million during the three months ended September 30, 2022, due primarily to a $3.6 million increase in intermodal revenues due primarily to reductions in shipping port logistical constraints which decreased intermodal cargo volumes in the prior year period, a $3.5 million increase in landfill gas revenue resulting from increased volumes generated and higher prices for renewable energy credits and a $1.0 million increase in other non-core revenue sources.  Other revenues increased $21.7 million during the nine months ended September 30, 2022, due primarily to a $9.6 million increase in landfill gas revenues and renewable energy credits, an $8.2 million increase in intermodal revenues and a $3.9 million increase in other non-core revenue sources.

Cost of Operations.  Total cost of operations increased $174.5 million, or 18.4%, to $1.121 billion for the three months ended September 30, 2022, from $946.1 million for the three months ended September 30, 2021. The increase was primarily the result of $101.8 million of additional operating costs from acquisitions closed during, or subsequent to, the three months ended September 30, 2021 and an increase in operating costs at our existing operations of $79.1 million, assuming foreign currency parity, partially offset by a decrease in operating costs of $4.0 million resulting from a lower average foreign currency exchange rate in effect during the current period and a decrease of $2.4 million from operations divested subsequent to the three months ended September 30, 2021.

The increase in operating costs of $79.1 million, assuming foreign currency parity, at our existing operations for the three months ended September 30, 2022 consisted of an increase in labor and recurring incentive compensation expenses of $24.0 million due primarily to employee pay increases, an increase in fuel expense of $16.8 million due to higher diesel and natural gas prices, an increase in third-party trucking and transportation expenses of $15.2 million due primarily to higher rates charged by third-party providers, an increase in truck, container, equipment and facility maintenance and repair expenses of $7.6 million due primarily to increased collection routes and equipment operating hours and parts and service rate increases, an increase in expenses for purchasing and processing recyclable commodities of $4.3 million due to processing expenses charged by third parties increasing as recyclable commodity values decline in certain of our regulated operating markets and the impact of recognizing certain recyclable commodity sales gross of selling and processing expenses, an increase in third-party disposal expenses of $4.0 million due primarily to disposal rate increases and higher roll off collection volumes, an increase in intermodal rail expenses of $2.0 million due to higher cargo volumes, an increase in subcontracted hauling services at our solid waste operations of $1.6 million due to higher costs charged by third-party providers, an increase in taxes on revenues of $1.2 million due primarily to increased revenues and $2.4 million of other net expense increases.

Total cost of operations increased $524.8 million, or 19.6%, to $3.198 billion for the nine months ended September 30, 2022, from $2.673 billion for the nine months ended September 30, 2021. The increase was primarily the result of $271.5 million of additional operating costs from acquisitions closed during, or subsequent to, the nine months ended September 30, 2021 and an increase in operating costs at our existing operations of $268.4 million, assuming foreign currency parity, partially offset by a decrease in operating costs of $8.4 million resulting from a lower average foreign currency exchange rate in effect during the current period and a decrease of $6.7 million from operations divested subsequent to the nine months ended September 30, 2021.

The increase in operating costs of $268.4 million, assuming foreign currency parity, at our existing operations for the nine months ended September 30, 2022 consisted of an increase in labor and recurring incentive compensation expenses of $71.0 million due primarily to employee pay increases, an increase in fuel expense of $57.4 million due to higher diesel and natural gas prices, an increase in third-party trucking and transportation expenses of $40.6 million due primarily to increased landfill special waste volumes requiring trucking and transportation services to our landfills and higher rates

We manage our operations through the following five geographic solid waste operating segments: Eastern, Southern, Western, Central and Canada. Our five geographic solid waste operating segments comprise our reportable segments.  Our Chief Operating Decision Maker evaluates operating segment profitability and determines resource allocations based on several factors, of which the primary financial measure is segment EBITDA. We define segment EBITDA as earnings before interest, taxes, depreciation, amortization, impairments and other operating items and other income (expense). Segment EBITDA is not a measure of operating income, operating performance or liquidity under GAAP and may not be comparable to similarly titled measures reported by other companies. Our management uses segment EBITDA in the evaluation of segment operating performance as it is a profit measure that is generally within the control of the operating segments.  Each operating segment is responsible for managing several vertically integrated operations, which are comprised of districts.

Summarized financial information for our reportable segments are shown in the following tables in thousands of U.S. dollars and as a percentage of total segment revenue for the periods indicated.

(a) The majority of Corporate expenses are allocated to the five operating segments.  Direct acquisition expenses, expenses associated with common shares held in the deferred compensation plan exchanged for other investment options and share-based compensation expenses associated with Progressive Waste share-based grants outstanding at June 1, 2016 that were continued by the Company are not allocated to the five operating segments and comprise the net EBITDA for our Corporate segment for the periods presented.

(b) For those items included in the determination of segment EBITDA, the accounting policies of the segments are the same as those described in our most recent Annual Report on Form 10-K.

A reconciliation of segment EBITDA to Income before income tax provision is included in Note 11 to our Condensed Consolidated Financial Statements included in Part 1, Item 1 of this report.

Significant changes in revenue, EBITDA and depreciation, depletion and amortization for our reportable segments for the three and nine month periods ended September 30, 2022, compared to the three and nine month periods ended September 30, 2021, are discussed below.

Eastern

Revenue increased $104.9 million to $501.1 million for the three months ended September 30, 2022, from $396.2 million for the three months ended September 30, 2021. Revenue increased $299.1 million to $1.401 billion for the nine months ended September 30, 2022, from $1.102 billion for the nine months ended September 30, 2021. The increase in revenues for the three and nine months ended September 30, 2022 was due to price increases, contributions from acquisitions and increased landfill gas sales attributable to higher volumes produced, partially offset by decreased residential collection volumes and lower prices for recyclable commodities.

EBITDA increased $26.5 million to $133.4 million for the three months ended September 30, 2022, from $106.9 million for the three months ended September 30, 2021. EBITDA margin was 26.6% and 27.0% for the three months ended September 30, 2022 and 2021, respectively. EBITDA increased $71.8 million to $367.2 million for the nine months ended September 30, 2022, from $295.4 million for the nine months ended September 30, 2021. EBITDA margin was 26.2% and 26.8% for the nine months ended September 30, 2022 and 2021, respectively. The decrease in our EBITDA margin for the three and nine months ended September 30, 2022 was due primarily to increased diesel fuel expenses, increased third-party trucking and transportation expenses, increased repair and maintenance expenses, increased corporate overhead allocations and increased travel, meetings, training and community activity expenses, partially offset by benefits from price-led revenue increases and the impact of acquisitions having higher EBITDA margins than our segment average.

44

Depreciation, depletion and amortization expense increased $11.3 million, to $72.3 million for the three months ended September 30, 2022, from $61.0 million for the three months ended September 30, 2021. Depreciation, depletion and amortization expense increased $34.3 million, to $207.8 million for the nine months ended September 30, 2022, from $173.5 million for the nine months ended September 30, 2021. The increase for the three and nine months ended September 30, 2022 was due to assets acquired in acquisitions, additions to our fleet and equipment and higher depletion expense due to higher landfill development costs increasing our per ton landfill depletion rates.

Southern

Revenue increased $57.4 million to $428.4 million for the three months ended September 30, 2022, from $371.0 million for the three months ended September 30, 2021. Revenue increased $159.4 million to $1.232 billion for the nine months ended September 30, 2022, from $1.072 billion for the nine months ended September 30, 2021. The increase in revenues for the three and nine months ended September 30, 2022 was due to solid waste price increases, increased E&P waste revenues attributable to increases in drilling and production activity levels resulting in increases in the demand for our E&P waste services and contributions from acquisitions, partially offset by lower residential collection volumes due to the loss of a collection contract subsequent to September 30, 2021, a decrease resulting from the divestiture of certain non-strategic operating locations and lower landfill special waste volumes.

EBITDA increased $31.1 million to $130.7 million for the three months ended September 30, 2022, from $99.6 million for the three months ended September 30, 2021.

The increase in our EBITDA margin for the three and nine months ended September 30, 2022 was due to increased earnings at our E&P operations and price-led increases in solid waste revenue, partially offset by increased diesel and natural gas fuel expenses, the impact of acquisitions having lower EBITDA margins than our segment average, increased cost of recyclable commodities expenses, increased travel, meetings, training and community activity expenses and increased legal expenses.

Depreciation, depletion and amortization expense increased $0.6 million, to $49.8 million for the three months ended September 30, 2022, from $49.2 million for the three months ended September 30, 2021. Depreciation, depletion and amortization expense increased $5.9 million, to $147.0 million for the nine months ended September 30, 2022, from $141.1 million for the nine months ended September 30, 2021. The increase for the three and nine months ended September 30, 2022 was due to assets acquired in acquisitions, additions to our fleet and equipment and higher depletion expense due to increased landfill volumes and higher landfill development costs increasing our per ton landfill depletion rates, partially offset by a decrease resulting from the divestiture of certain non-strategic operating locations, a reduction in amortization expense associated with the loss of a large residential collection contract and a decrease in depletion expense resulting  from non-recurring charges recorded in the prior year period to adjust landfill closure liabilities.

Canada

Revenue increased $18.0 million to $242.3 million for the three months ended September 30, 2022, from $224.3 million for the three months ended September 30, 2021, due to price increases, contributions from acquisitions, higher commercial and roll off collection volumes and higher prices for renewable energy credits associated with the generation of landfill gas, partially offset by a decrease in the average foreign currency exchange rate in effect during the comparable reporting periods, lower prices for recyclable commodities, lower residential collection volumes due to the loss of a collection contract subsequent to September 30, 2021, lower landfill volumes and the divestiture of a non-strategic operating location.

Operating Activities Cash Flows

For the nine months ended September 30, 2022, net cash provided by operating activities was $1.500 billion. For the nine months ended September 30, 2021, net cash provided by operating activities was $1.270 billion. The $230.2 million increase was due primarily to the following:

1) Increase in earnings — Our increase in net cash provided by operating activities was favorably impacted by $156.0 million from an increase in net income, excluding depreciation, amortization of intangibles, share-based compensation, adjustments to and payments of contingent consideration recorded in earnings and loss on disposal of assets and impairments, due primarily to price increases, earnings from acquisitions, earnings generated from an increase in landfill gas revenues and renewable energy credits and an increase in earnings at our E&P waste operations.

2) Deferred income taxes — Our increase in net cash provided by operating activities was favorably impacted by $115.4 million from deferred income taxes as changes in deferred income taxes resulted in an increase to operating cash flows of $91.1 million for the nine months ended September 30, 2022, compared to a decrease to operating cash flows of $24.3 million for the nine months ended September 30, 2021. The increase for the nine months ended September 30, 2022 was attributable to capital expenditures providing tax benefits resulting from accelerated depreciation and tax benefits resulting from the divestiture of certain non-strategic E&P disposal operating locations. The decrease in deferred taxes for the nine months ended September 30, 2021 was primarily due to the tax deduction timing of make-whole premium payments attributable to the early extinguishment of the outstanding senior notes under our master note purchase agreements.

3) Accounts payable and accrued liabilities — Our increase in net cash provided by operating activities was favorably impacted by $74.0 million from accounts payable and accrued liabilities as changes in accounts payable and accrued liabilities resulted in an increase to operating cash flows of $126.7 million for the nine months ended September 30, 2022, compared to an increase to operating cash flows of $52.7 million for the nine months ended September 30, 2021. The increase for the nine months ended September 30, 2022 was due primarily to increases in operating expenses during the period which remained as outstanding obligations at September 30, 2022,  increased accrued interest due to the timing of interest payments for our senior unsecured notes issued subsequent to September 30, 2021, increased property taxes attributable to payment timing and the timing of payroll cycles, partially offset by the payment of annual cash incentive compensation to our management, which was accrued as a liability at year end. The increase for the nine months ended September 30, 2021 was due primarily to increases in operating expenses during the period which remained as outstanding obligations at September 30, 2021, the settlement of an acquired compensation liability and the timing of payroll cycles.

4) Deferred revenue — Our increase in net cash provided by operating activities was favorably impacted by $10.7 million from deferred revenue as changes in deferred revenue resulted in an increase to operating cash flows of $26.5 million for the nine months ended September 30, 2022, compared to an increase to operating cash flows of $15.8 million for the nine months ended September 30, 2021. For both comparative periods, deferred revenue increased due to price increases on our advanced billed residential and commercial collection services.

48

5) Accounts receivable – Our increase in net cash provided by operating activities was unfavorably impacted by $39.0 million from accounts receivable as changes in accounts receivable resulted in a decrease to operating cash flows of $90.6 million for the nine months ended September 30, 2022, compared to a decrease to operating cash flows of $51.6 million for the nine months ended September 30, 2021. The decrease for the nine months ended September 30, 2022 was due to increases in revenues, which remained as outstanding receivables at September 30, 2022. The decrease for the nine months ended September 30, 2021 was due to increases in revenues, which remained as outstanding receivables at September 30, 2021.

6) Other long-term liabilities – Our increase in net cash provided by operating activities was unfavorably impacted by $24.9 million from other long-term liabilities as changes in other long-term liabilities resulted in a decrease to operating cash flows of $12.2 million for the nine months ended September 30, 2022, compared to an increase to operating cash flows of $12.7 million for the nine months ended September 30, 2021. The decrease for the nine months ended September 30, 2022 was due primarily to decreased employee deferred compensation liabilities. The increase for the nine months ended September 30, 2021 was primarily attributable to the receipt of funds associated with the eminent domain purchase of an operating facility that will be replaced with a newly constructed facility in a future period and an increase in employee deferred compensation liabilities.

7) Prepaid expenses – Our increase in net cash provided by operating activities was unfavorably impacted by $59.1 million from prepaid expenses as changes in prepaid expenses resulted in a decrease to operating cash flows of $22.9 million for the nine months ended September 30, 2022, compared to an increase to operating cash flows of $36.2 million for the nine months ended September 30, 2021. The decrease for the nine months ended September 30, 2022 was due primarily to increases from payments of annual insurance premiums and higher parts and fuel inventory. The increase for the nine months ended September 30, 2021 was due primarily to decreases in prepaid income tax payments and prepaid vendor payments.

As of September 30, 2022, we had a working capital deficit of $148.4 million, including cash and equivalents of $200.2 million.  Our working capital increased $51.6 million from a working capital deficit of $200.0 million at December 31, 2021 including cash and equivalents of $147.4 million, due primarily to an increase in cash balances, accounts receivable and prepaid expenses, partially offset by an increase in accounts payable and deferred revenue. To date, we have experienced no loss or lack of access to our cash and equivalents; however, we can provide no assurances that access to our cash and equivalents will not be impacted by adverse conditions in the financial markets.  Our strategy in managing our working capital is generally to apply the cash generated from our operations that remains after satisfying our working capital and capital expenditure requirements, along with share repurchase and dividend programs, to reduce the unhedged portion of our indebtedness under our Credit Agreement and to minimize our cash balances.

Investing Activities Cash Flows

Net cash used in investing activities increased $823.7 million to $1.859 billion for the nine months ended September 30, 2022, from $1.035 billion for the nine months ended September 30, 2021. The significant components of the increase included the following:

1) An increase in cash paid for acquisitions of $711.6 million;

2) An increase in capital expenditures at operations owned in the comparable periods of $87.3 million due to increases in land and buildings, landfill site costs, trucks, equipment and containers; and

3) An increase in capital expenditures at operations acquired during the comparative periods of $51.5 million due to additional trucks, equipment and containers; less

4) An increase in proceeds from disposal of assets of $13.2 million due to additional disposal of non-strategic assets to provide funding toward new capital expenditures.

49

Financing Activities Cash Flows

Net cash provided by financing activities increased $942.0 million to $450.4 million for the nine months ended September 30, 2022, from net cash used in financing activities of $491.6 million for the nine months ended September 30, 2021. The significant components of the increase included the following:

1) An increase from the net change in long-term borrowings of $966.1 million (long-term borrowings increased $1.098 billion during the nine months ended September 30, 2022 and increased $131.9.million during the nine months ended September 30, 2021); less

2) A decrease from higher payments to repurchase our common shares of $119.4 million due to an increased volume of shares repurchased; less

3) A decrease from higher cash dividends paid of $17.0 million due primarily to an increase in our quarterly dividend rate for the nine months ended September 30, 2022 to $0.23 per share, from $0.205 per share for the nine months ended September 30, 2021; less

4) A decrease from higher debt issuance costs of $6.5 million attributable to senior note offerings completed in 2022.

Our business is capital intensive. Our capital requirements include acquisitions and capital expenditures for landfill cell construction, landfill development, landfill closure activities and intermodal facility construction in the future.

On July 26, 2022, our Board of Directors approved, subject to receipt of regulatory approvals, the annual renewal of our normal course issuer bid, or the NCIB, to purchase up to 12,859,066 of our common shares during the period of August 10, 2022 to August 9, 2023 or until such earlier time as the NCIB is completed or terminated at our option. Shareholders may obtain a copy of our TSX Form 12 – Notice of Intention to Make a Normal Course Issuer Bid, without charge, by request directed to our Executive Vice President and Chief Financial Officer at (832) 442-2200.  The timing and amounts of any repurchases pursuant to the NCIB will depend on many factors, including our capital structure, the market price of our common shares and overall market conditions. All common shares purchased under the NCIB will be immediately cancelled following their repurchase.  Information regarding our NCIB can be found under the “Normal Course Issuer Bid” section in Note 17 to the Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q and is incorporated herein by reference.

Our Board of Directors authorized the initiation of a quarterly cash dividend in October 2010 and has increased it on an annual basis. In October 2021, our Board of Directors authorized an increase to our regular quarterly cash dividend of $0.025, from $0.205 to $0.230 per share.  In October 2022, our Board of Directors authorized an increase to our regular quarterly cash dividend of $0.025, from $0.230 to $0.255 per share.  Cash dividends of $177.7 million and $160.8 million were paid during the nine months ended September 30, 2022 and 2021, respectively. We cannot assure you as to the amounts or timing of future dividends.

We made $618.3 million in capital expenditures for property and equipment during the nine months ended September 30, 2022, and we expect to make total capital expenditures for property and equipment of approximately $850 million in 2022, net of asset sales.  We have funded and intend to fund the balance of our planned 2022 capital expenditures principally through cash on hand, internally generated funds and borrowings under our Credit Agreement. In addition, we may make substantial additional capital expenditures in acquiring land and solid waste businesses. If we acquire additional landfill disposal facilities, we may also have to make significant expenditures to bring them into compliance with applicable regulatory requirements, obtain permits or expand our available disposal capacity. We cannot currently determine the amount of these expenditures because they will depend on the number, nature, condition and permitted status of any acquired landfill disposal facilities. We believe that our cash and equivalents, Credit Agreement and the funds we expect to generate from operations will provide adequate cash to fund our working capital and other cash needs for the foreseeable future. However, disruptions in the capital and credit markets could adversely affect our ability to draw on our Credit Agreement or raise other capital. Our access to funds under the Credit Agreement is dependent on the ability of the banks that are parties to the agreement to meet their funding commitments. Those banks may not be able to meet their funding commitments if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests within a short period of time.

3) $500.0 million in principal payments due 2028 related to our 2028 Senior Notes. The 2028 Senior Notes bear interest at a rate of 4.25%.

4) $500.0 million in principal payments due 2029 related to our 2029 Senior Notes. The 2029 Senior Notes bear interest at a rate of 3.50%.

5) $600.0 million in principal payments due 2030 related to our 2030 Senior Notes. The 2030 Senior Notes bear interest at a rate of 2.60%.

6) $650.0 million in principal payments due 2032 related to our 2032 Senior Notes. The 2032 Senior Notes bear interest at a rate of 2.20%.

7) $500.0 million in principal payments due 2032 related to our New 2032 Senior Notes. The New 2032 Senior Notes bear interest at a rate of 3.20%.

8) $750.0 million in principal payments due 2033 related to our 2033 Senior Notes. The 2033 Senior Notes bear interest at a rate of 4.20%.

9) $500.0 million in principal payments due 2050 related to our 2050 Senior Notes. The 2050 Senior Notes bear interest at a rate of 3.05%.

10) $850.0 million in principal payments due 2052 related to our 2052 Senior Notes. The 2052 Senior Notes bear interest at a rate of 2.95%.

52

11) $34.4 million in principal payments related to our notes payable to sellers and other third parties. Our notes payable to sellers and other third parties bear interest at rates between 2.42% and 10.35% at September 30, 2022, and have maturity dates ranging from 2028 to 2036.

12) $12.1 million in principal payments related to our financing leases.  Our financing leases bear interest at rates between 1.89% and 2.16% at September 30, 2022, and have expiration dates ranging from 2026 to 2027.

The following assumptions were made in calculating cash interest payments:

1) We calculated cash interest payments on the Credit Agreement using the LIBOR rate plus the applicable LIBOR margin, the base rate plus the applicable base rate margin, the Canadian Dollar Offered Rate plus the applicable acceptance fee and the Canadian prime rate plus the applicable prime rate margin at September 30, 2022. We assumed the Credit Agreement is paid off when it matures in July 2026.

2) We calculated cash interest payments on our interest rate swaps using the stated interest rate in the swap agreement less the LIBOR rate through the earlier expiration of the term of the swaps or the term of the credit facility.

Contingent consideration payments include $85.8 million recorded as liabilities in our Condensed Consolidated Financial Statements at September 30, 2022, and $18.0 million of future interest accretion on the recorded obligations.

We are party to operating lease agreements and finance leases. These lease agreements are established in the ordinary course of our business and are designed to provide us with access to facilities and equipment at competitive, market-driven prices.

The estimated final capping, closure and post-closure expenditures presented above are in current dollars.

____________________

(1) We are party to unconditional purchase obligations. These purchase obligations are established in the ordinary course of our business and are designed to provide us with access to products at competitive, market-driven prices. At September 30, 2022, our unconditional purchase obligations consisted of multiple fixed-price fuel purchase contracts under which we have 35.5 million gallons remaining to be purchased for a total of $92.5 million. The current fuel purchase contracts expire on or before December 31, 2024. These arrangements have not materially affected our financial position, results of operations or liquidity during the nine months ended September 30, 2022, nor are they expected to have a material impact on our future financial position, results of operations or liquidity.

We have obtained financial surety bonds, primarily to support our financial assurance needs and landfill and E&P operations. We provided customers and various regulatory authorities with surety bonds in the aggregate amounts of approximately $1.425 billion and $1.301 billion at September 30, 2022 and December 31, 2021, respectively. These arrangements have not materially affected our financial position, results of operations or liquidity during the nine months ended September 30, 2022, nor are they expected to have a material impact on our future financial position, results of operations or liquidity.

From time to time, we evaluate our existing operations and their strategic importance to us. If we determine that a given operating unit does not have future strategic importance, we may sell or otherwise dispose of those operations. Although we believe our reporting units would not be impaired by such dispositions, we could incur losses on them.

NON-GAAP FINANCIAL MEASURES

Adjusted Free Cash Flow

We present adjusted free cash flow, a non-GAAP financial measure, supplementally because it is widely used by investors as a valuation and liquidity measure in the solid waste industry. Management uses adjusted free cash flow as one of the principal measures to evaluate and monitor the ongoing financial performance of our operations. We define adjusted free cash flow as net cash provided by operating activities, plus or minus change in book overdraft, plus proceeds from disposal of assets, less capital expenditures for property and equipment and distributions to noncontrolling interests. We further adjust this calculation to exclude the effects of items management believes impact the ability to assess the operating performance of our business. This measure is not a substitute for, and should be used in conjunction with, GAAP liquidity or financial measures. Other companies may calculate adjusted free cash flow differently. Our adjusted free cash flow for the nine month periods ended September 30, 2022 and 2021, are calculated as follows (amounts in thousands of U.S. dollars):

	Nine Months Ended
	September 30,
	2022		2021

55

Adjusted EBITDA

We present adjusted EBITDA, a non-GAAP financial measure, supplementally because it is widely used by investors as a performance and valuation measure in the solid waste industry. Management uses adjusted EBITDA as one of the principal measures to evaluate and monitor the ongoing financial performance of our operations. We define adjusted EBITDA as net income attributable to Waste Connections, plus or minus net income (loss) attributable to noncontrolling interests, plus income tax provision, plus interest expense, less interest income, plus depreciation and amortization expense, plus closure and post-closure accretion expense, plus or minus any loss or gain on impairments and other operating items, plus other expense, less other income. We further adjust this calculation to exclude the effects of other items management believes impact the ability to assess the operating performance of our business. This measure is not a substitute for, and should be used in conjunction with, GAAP financial measures. Other companies may calculate adjusted EBITDA differently. Our adjusted EBITDA for the three and nine month periods ended September 30, 2022 and 2021, are calculated as follows (amounts in thousands of U.S. dollars):

	Three Months Ended				Nine Months Ended

Adjusted Net Income Attributable to Waste Connections and Adjusted Net Income per Diluted Share Attributable to Waste Connections

We present adjusted net income attributable to Waste Connections and adjusted net income per diluted share attributable to Waste Connections, both non-GAAP financial measures, supplementally because they are widely used by investors as a valuation measure in the solid waste industry. Management uses adjusted net income attributable to Waste Connections and adjusted net income per diluted share attributable to Waste Connections as one of the principal measures to evaluate and monitor the ongoing financial performance of our operations. We provide adjusted net income attributable to Waste Connections to exclude the effects of items management believes impact the comparability of operating results between periods. Adjusted net income attributable to Waste Connections has limitations due to the fact that it excludes items that have an impact on our financial condition and results of operations. Adjusted net income attributable to Waste Connections and adjusted net income per diluted share attributable to Waste Connections are not a substitute for, and should be used in conjunction with, GAAP financial measures. Other companies may calculate these non-GAAP financial measures differently. Our adjusted net income attributable to Waste Connections and adjusted net income per diluted share attributable to Waste Connections for the three and nine month periods ended September 30, 2022 and 2021, are calculated as follows (amounts in thousands of U.S. dollars, except per share amounts):

INFLATION

In the current environment, we have seen inflationary pressures resulting from higher fuel, materials and labor costs in certain markets and higher resulting third-party costs in areas such as brokerage, repairs and construction.  Consistent with industry practice, many of our contracts allow us to pass through certain costs to our customers, including increases in landfill tipping fees and, in some cases, fuel costs.  To the extent that there are decreases in fuel costs, in some cases, a portion of these reductions are passed through to customers in the form of lower fuel and material surcharges. Therefore, we believe that we should be able to increase prices to offset many cost increases that result from inflation in the ordinary course of business. However, competitive pressures or delays in the timing of rate increases under certain of our contracts may require us to absorb at least part of these cost increases, especially if cost increases exceed the average rate of inflation. Management’s estimates associated with inflation have an impact on our accounting for landfill liabilities.

57

SEASONALITY

Based on historic trends, excluding any impact from the COVID-19 pandemic or an economic recession, we would expect our operating results to vary seasonally, with revenues typically lowest in the first quarter, higher in the second and third quarters and lower in the fourth quarter than in the second and third quarters. This seasonality reflects (a) the lower volume of solid waste generated during the late fall, winter and early spring because of decreased construction and demolition activities during winter months in Canada and the U.S. and (b) reduced E&P activity during harsh weather conditions, with expected fluctuation due to such seasonality between our highest and lowest quarters of approximately 10%. In addition, some of our operating costs may be higher in the winter months. Adverse winter weather conditions slow waste collection activities, resulting in higher labor and operational costs. Greater precipitation in the winter increases the weight of collected municipal solid waste, resulting in higher disposal costs, which are calculated on a per ton basis.

Item 3.Quantitative and Qualitative Disclosures About Market Risk

In the normal course of business, we are exposed to market risk, including changes in interest rates and prices of certain commodities, and to a lesser extent, foreign currency exchange rate risks. We use hedge agreements to manage a portion of our risks related to interest rates. While we are exposed to credit risk in the event of non-performance by counterparties to our hedge agreements, in all cases such counterparties are highly rated financial institutions and we do not anticipate non-performance under current market conditions. We do not hold or issue derivative financial instruments for trading purposes. We monitor our hedge positions by regularly evaluating the positions at market and by performing sensitivity analyses over the unhedged variable rate debt positions.

At September 30, 2022, our derivative instruments included five interest rate swap agreements that effectively fix the interest rate on the applicable notional amounts of our variable rate debt as follows (dollars in thousands of U.S. dollars):

			Fixed		Variable
	Notional		Interest		Interest Rate		Expiration
Date Entered	Amount		Rate Paid*		Received	Effective Date	Date
August 2017	$	200,000	2.200	%	1-month LIBOR	October 2020	October 2025
August 2017	$	150,000	1.950	%	1-month LIBOR	February 2020	February 2023
June 2018	$	200,000	2.925	%	1-month LIBOR	October 2020	October 2025
June 2018	$	200,000	2.925	%	1-month LIBOR	October 2020	October 2025
December 2018	$	200,000	2.850	%	1-month LIBOR	July 2022	July 2027

____________________

* Plus applicable margin.

Under derivatives and hedging guidance, the interest rate swap agreements are considered cash flow hedges for a portion of our variable rate debt, and we apply hedge accounting to account for these instruments. The notional amounts and all other significant terms of the swap agreements are matched to the provisions and terms of the variable rate debt being hedged.

We have performed sensitivity analyses to determine how market rate changes will affect the fair value of our unhedged floating rate debt. Such an analysis is inherently limited in that it reflects a singular, hypothetical set of assumptions. Actual market movements may vary significantly from our assumptions. Fair value sensitivity is not necessarily indicative of the ultimate cash flow or earnings effect we would recognize from the assumed market rate movements. We are exposed to cash flow risk due to changes in interest rates with respect to the unhedged floating rate balances owed at September 30, 2022 and December 31, 2021, of $438.2 million and $603.9 million, respectively, including floating rate debt under our Credit Agreement. A one percentage point increase in interest rates on our variable-rate debt as of September 30, 2022 and December 31, 2021, would decrease our annual pre-tax income by approximately $4.4 million and $6.0 million, respectively. All of our remaining debt instruments are at fixed rates, or effectively fixed under the interest rate swap agreements described above; therefore, changes in market interest rates under these instruments would not significantly impact our cash flows or results of operations, subject to counterparty default risk.

58

The market price of diesel fuel is unpredictable and can fluctuate significantly.  Because of the volume of fuel we purchase each year, a significant increase in the price of fuel could adversely affect our business and reduce our operating margins.  To manage a portion of this risk, we periodically enter into fuel hedge agreements related to forecasted diesel fuel purchases, and we also enter into fixed price fuel purchase contracts.  At September 30, 2022, we had no fuel hedge agreements in place; however, we have entered into fixed price fuel purchase contracts for 2022 as described below.

For the year ending December 31, 2022, we expect to purchase approximately 88.0 million gallons of fuel, of which 43.9 million gallons will be purchased at market prices and 44.1 million gallons will be purchased under our fixed price fuel purchase contracts. We have performed sensitivity analyses to determine how market rate changes will affect the fair value of our unhedged, market rate diesel fuel purchases.  Such an analysis is inherently limited in that it reflects a singular, hypothetical set of assumptions.  Actual market movements may vary significantly from our assumptions.  Fair value sensitivity is not necessarily indicative of the ultimate cash flow or earnings effect we would recognize from the assumed market rate movements.  During the three month period of October 1, 2022 to December 31, 2022, we expect to purchase approximately 11.0 million gallons of fuel at market prices; therefore, a $0.10 per gallon increase in the price of fuel over the remaining three months in 2022 would decrease our pre-tax income during this period by approximately $1.1 million.

We market a variety of recyclable materials, including compost, cardboard, mixed paper, plastic containers, glass bottles and ferrous and aluminum metals. We own and operate recycling operations and market collected recyclable materials to third parties for processing before resale. Where possible, to reduce our exposure to commodity price risk with respect to recycled materials, we have adopted a pricing strategy of charging collection and processing fees for recycling volume collected from third parties. In the event of a decline in recycled commodity prices, a 10% decrease in average recycled commodity prices from the average prices that were in effect during the nine months ended September 30, 2022 and 2021, would have had a $17.1 million and $12.6 million impact on revenues for the nine months ended September 30, 2022 and 2021, respectively.

We have operations in Canada and, where significant, we have quantified and described the impact of foreign currency translation on components of income, including operating revenue and operating costs. However, the impact of foreign currency has not materially affected our results of operations in 2021 or 2022. A $0.01 change in the Canadian dollar to U.S. dollar exchange rate would impact our annual revenue and EBITDA by approximately $12.0 million and $4.5 million, respectively.

Item 4.Controls and Procedures

As required by Rule 13a-15(b) under the U.S. Securities Exchange Act of 1934, as amended, or the Exchange Act, we carried out an evaluation, under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Executive Vice President and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Exchange Act) as of the end of the fiscal quarter covered by this Quarterly Report on Form 10-Q. In designing and evaluating the disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Based on this evaluation, our President and Chief Executive Officer and our Executive Vice President and Chief Financial Officer concluded as of September 30, 2022, that our disclosure controls and procedures were effective at the reasonable assurance level such that information required to be disclosed in our Exchange Act reports:  (1) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms; and (2) is accumulated and communicated to our management, including our President and Chief Executive Officer and Executive Vice President and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

During the quarter ended September 30, 2022, there was no change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

1.BASIS OF PRESENTATION AND SUMMARY

The accompanying condensed consolidated financial statements relate to Waste Connections, Inc. and its subsidiaries (the “Company”) for the three and nine month periods ended September 30, 2022 and 2021. In the opinion of management, the accompanying balance sheets and related interim statements of net income, comprehensive income, cash flows and equity include all adjustments, consisting only of normal recurring items, necessary for their fair statement in conformity with U.S. generally accepted accounting principles (“GAAP”). Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Examples include accounting for landfills, self-insurance accruals, income taxes, allocation of acquisition purchase price, contingent consideration accruals and asset impairments. An additional area that involves estimation is when the Company estimates the amount of potential exposure it may have with respect to litigation, claims and assessments in accordance with the accounting guidance on contingencies. Actual results for all estimates could differ materially from the estimates and assumptions that the Company uses in the preparation of its condensed consolidated financial statements.

Interim results are not necessarily indicative of results for a full year. These interim financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

3.NEW ACCOUNTING STANDARDS

Accounting Standards Pending Adoption

Reference Rate Reform – Facilitation of the Effects of Reference Rate Reform on Financial Reporting.  In March 2020, the Financial Accounting Standards Board (“FASB”) issued guidance to provide temporary optional expedients and exceptions to the guidance in GAAP on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (“SOFR”).  One-week and two-month U.S. dollar LIBOR settings as well as all non-U.S. dollar LIBOR settings stopped being published on December 31, 2021, while the remaining U.S. dollar LIBOR settings will be discontinued on June 30, 2023.  Under the new guidance, entities can elect not to apply certain modification accounting requirements to contracts affected by reference rate reform, if certain criteria are met.  An entity that makes this election would not have to remeasure the contracts at the modification date or reassess a previous accounting determination.  Under the guidance, entities can also elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met.

The guidance was effective upon issuance.  The guidance on contract modifications was applied prospectively from March 12, 2020.  The guidance on hedging is applied to eligible hedging relationships existing as of the beginning of the

interim period that includes the effective date and to new eligible hedging relationships entered into after the beginning of that interim period.  The relief is temporary and generally cannot be applied to contract modifications that occur after December 31, 2022 or hedging relationships entered into or evaluated after that date.  However, certain optional expedients can be applied to hedging relationships evaluated in periods after December 31, 2022.  

The Company determined that the new guidance will not have a material effect on its consolidated financial statements.  The Company had a combined $1,251,000 of U.S. LIBOR based loans as of September 30, 2022. The Company estimates that if the reference rate for these loans had transitioned from LIBOR to SOFR as of September 30, 2022, the impact to annual interest expense would have been immaterial.  

In October 2022, the Company adopted the applicable practical expedients of the standard when it converted the option of a LIBOR interest rate in its Credit Agreement to a SOFR interest rate and correspondingly amended its five interest rate swap agreements that are specifically designated to the amended Credit Agreement.  As permitted by the practical expedients in the standard, the Company maintained cash flow hedge accounting for its interest rate swap agreements as the conversion of the LIBOR interest rate to SOFR was the only modification to the interest rate swap agreements.  See Notes 10 and 19 for further details on the amendment to the Credit Agreement.

The Company’s operations primarily consist of providing non-hazardous waste collection, transfer, disposal and recycling services, non-hazardous oil and natural gas exploration and production (“E&P”) waste treatment, recovery and disposal services and intermodal services. The following table disaggregates the Company’s revenues by service line for the periods indicated:

Total	$	1,879,868	$	1,597,168	$	5,342,558	$	4,527,042

The factors that impact the timing and amount of revenue recognized for each service line may vary based on the nature of the service performed. Generally, the Company recognizes revenue at the time it performs a service. In the event that the Company bills for services in advance of performance, it recognizes deferred revenue for the amount billed and subsequently recognizes revenue at the time the service is provided.  Substantially all of the deferred revenue recorded as of June 30, 2022 was recognized as revenue during the three months ended September 30, 2022 when the service was performed.

See Note 11 for additional information regarding revenue by reportable segment.

Contract Acquisition Costs

The incremental direct costs of obtaining a contract, which consist of sales incentives, are recognized as Other assets in the Company’s Condensed Consolidated Balance Sheet, and are amortized to Selling, general and administrative expense over the estimated life of the relevant customer relationship, which ranges from one to five years. The Company recognizes the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company would have recognized is one year or less.  The Company had $19,627 and $18,954 of deferred sales incentives at September 30, 2022 and December 31, 2021, respectively.

5.ACCOUNTS RECEIVABLE

Accounts receivable are recorded when billed or accrued and represent claims against third parties that will be settled in cash. The carrying value of the Company’s receivables, net of the allowance for credit losses, represents their estimated net realizable value.

The allowance for credit losses is based on management’s assessment of the collectability of assets pooled together with similar risk characteristics.  The Company monitors the collectability of its trade receivables as one overall pool due to all trade receivables having similar risk characteristics.  The Company estimates its allowance for credit losses based on historical collection trends, the age of outstanding receivables, geographical location of the customer, existing economic conditions and reasonable forecasts. If events or changes in circumstances indicate that specific receivable balances may be impaired, further consideration is given to the collectability of those balances and the allowance is adjusted accordingly. Past-due receivable balances are written off when the Company’s internal collection efforts have been unsuccessful in collecting the amount due.

The following is a rollforward of the Company’s allowance for credit losses for the periods indicated:

Landfill Accounting [Abstract]

Landfill Accounting

6.LANDFILL ACCOUNTING

At September 30, 2022, the Company’s landfills consisted of 86 owned landfills, five landfills operated under life-of-site operating agreements and five landfills operated under limited-term operating agreements. The Company’s landfills had site costs with a net book value of $2,949,498 at September 30, 2022. For the Company’s landfills operated under limited-term operating agreements and life-of-site operating agreements, the owner of the property (generally a municipality) usually owns the permit and the Company operates the landfill for a contracted term. Where the contracted term is not the life of the landfill, the property owner is generally responsible for final capping, closure and post-closure obligations. The Company is responsible for all final capping, closure and post-closure liabilities at the landfills it operates under life-of-site operating agreements.

The Company’s internal and third-party engineers perform surveys at least annually to estimate the remaining disposal capacity at its landfills. Many of the Company’s existing landfills have the potential for expanded disposal capacity beyond the amount currently permitted. The Company’s landfill depletion rates are based on the remaining disposal capacity, considering both permitted and probable expansion airspace, at the landfills it owns and landfills it operates, but does not own, under life-of-site agreements. The Company’s landfill depletion rate is based on the term of the operating agreement at its operated landfill that has capitalized expenditures. Expansion airspace consists of additional disposal capacity being pursued through means of an expansion that has not yet been permitted. Expansion airspace that meets certain criteria is included in the estimate of total landfill airspace.

Based on remaining permitted capacity as of September 30, 2022, and projected annual disposal volumes, the average remaining landfill life for the Company’s owned landfills and landfills operated under life-of-site operating agreements is estimated to be approximately 30 years. As of September 30, 2022, the Company is seeking to expand permitted capacity at eight of its owned landfills and two landfills that it operates under life-of-site operating agreements, and considers the achievement of these expansions to be probable. Although the Company cannot be certain that all future expansions will be permitted as designed, the average remaining life, when considering remaining permitted capacity, probable expansion capacity and projected annual disposal volume, of the Company’s owned landfills and landfills operated under life-of-site operating agreements is approximately 34 years.  The estimated remaining lives of the Company’s owned landfills and landfills operated under life-of-site operating agreements range from 1 to 330 years, with approximately 90% of the projected annual disposal volume from landfills with remaining lives of less than 70 years.

During the nine months ended September 30, 2022 and 2021, the Company expensed $172,118 and $160,470, respectively, or an average of $4.88 and $4.56 per ton consumed, respectively, related to landfill depletion at owned landfills and landfills operated under life-of-site agreements.

The Company reserves for estimated final capping, closure and post-closure maintenance obligations at the landfills it owns and landfills it operates under life-of-site operating agreements. The Company calculates the net present value of its final capping, closure and post-closure liabilities by estimating the total obligation in current dollars, inflating the obligation based upon the expected date of the expenditure and discounting the inflated total to its present value using a credit-adjusted risk-free rate. Any changes in expectations that result in an upward revision to the estimated undiscounted cash flows are treated as a new liability and are inflated and discounted at rates reflecting market conditions. Any changes in expectations that result in a downward revision (or no revision) to the estimated undiscounted cash flows result in a liability that is inflated and discounted at rates reflecting the market conditions at the time the cash flows were originally estimated. This policy results in the Company’s final capping, closure and post-closure liabilities being recorded in “layers.”  The Company’s discount rate assumption for purposes of computing 2022 and 2021 “layers” for final capping, closure and post-closure obligations was 3.25% for both years, which reflects the Company’s long-term credit adjusted risk free rate as of the end of 2021 and 2020. The Company’s long-term inflation rate assumption is 2.25% for the years ending December 31, 2022 and 2021. The resulting final capping, closure and post-closure obligations are recorded on the Condensed Consolidated Balance Sheet along with an offsetting addition to site costs which is amortized to depletion expense as the remaining landfill airspace is consumed. Interest is accreted on the recorded liability using the corresponding discount rate. During the nine months ended September 30, 2022 and 2021, the Company expensed $12,008 and $10,783, respectively, or an average of $0.34 and $0.31 per ton consumed, respectively, related to final capping, closure and post-closure accretion expense.

The following is a reconciliation of the Company’s final capping, closure and post-closure liability balance from December 31, 2021 to September 30, 2022:

Final capping, closure and post-closure liability at December 31, 2021	$	302,537
Liability adjustments		36,152
Accretion expense associated with landfill obligations		12,008
Closure payments		(11,867)
Assumption of closure liabilities from acquisitions		3,498
Disposition of closure liabilities from divested operations		(916)
Foreign currency translation adjustment		(2,518)
Final capping, closure and post-closure liability at September 30, 2022	$	338,894

Liability adjustments of $36,152 for the nine months ended September 30, 2022, represent non-cash changes to final capping, closure and post-closure liabilities and are recorded on the Condensed Consolidated Balance Sheets along with an offsetting addition to site costs, which is amortized to depletion expense as the remaining landfill airspace is consumed. The final capping, closure and post-closure liability is included in Other long-term liabilities in the Condensed Consolidated Balance Sheets.  The Company performs its annual review of its cost and capacity estimates in the first quarter of each year.

At September 30, 2022 and December 31, 2021, $10,632 and $12,609, respectively, of the Company’s restricted cash balance and $53,243 and $56,289, respectively, of the Company’s restricted investments balance was for purposes of securing its performance of future final capping, closure and post-closure obligations.

Goodwill acquired during the nine months ended September 30, 2022 and 2021, totaling $272,186 and $114,006, respectively, is expected to be deductible for tax purposes.

The fair value of acquired working capital related to 11 individually immaterial acquisitions completed during the twelve months ended September 30, 2022, is provisional pending receipt of information from the acquirees to support the fair value of the assets acquired and liabilities assumed. Any adjustments recorded relating to finalizing the working capital for these 11 acquisitions are not expected to be material to the Company’s financial position.

The gross amount of trade receivables due under contracts acquired during the nine months ended September 30, 2022, was $37,486, of which $5,157 was expected to be uncollectible. The gross amount of trade receivables due under contracts acquired during the nine months ended September 30, 2021, was $21,673, of which $1,881 was expected to be uncollectible. The Company did not acquire any other class of receivable as a result of the acquisition of these businesses.

Lessee Disclosure [Abstract]

Leases

9.LEASES

The Company rents certain equipment and facilities under short-term agreements, non-cancelable operating lease agreements and finance leases.  The Company determines if an arrangement is or contains a lease at contract inception. The Company recognizes a right-of-use (“ROU”) asset and a lease liability at the lease commencement date.  The lease liability is initially measured at the present value of the unpaid lease payments at the lease commencement date.

Key estimates and judgments include how the Company determines (1) the discount rate it uses to discount the unpaid lease payments to present value, (2) lease term and (3) lease payments.

The lease guidance requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. Generally, the Company cannot determine the interest rate implicit in the lease because it does not have access to the lessor’s estimated residual value or the amount of the lessor’s deferred initial direct costs.  Therefore, the Company generally uses its incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms.

The lease term for the Company’s leases includes the noncancelable period of the lease, plus any additional periods covered by either a Company option to extend (or not to terminate) the lease that the Company is reasonably certain to exercise, or an option to extend (or not to terminate) the lease controlled by the lessor.

Lease payments included in the measurement of the lease liability comprise fixed payments or variable lease payments.  The variable lease payments take into account annual changes in the consumer price index and common area maintenance charges, if known.

ROU assets for operating and finance leases are periodically reviewed for impairment losses. The Company uses the long-lived asset impairment guidance in ASC Subtopic 360-10, Property, Plant, and Equipment – Overall, to determine whether an ROU asset is impaired, and if so, the amount of the impairment loss to recognize.  The Company did not recognize an impairment charge for any of its ROU assets during the nine months ended September 30, 2022 and 2021.

The Company monitors for events or changes in circumstances that require a reassessment of one of its leases. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the corresponding ROU asset.  The Company did not recognize any significant remeasurements during the nine months ended September 30, 2022 and 2021.

The Company has elected not to recognize ROU assets and lease liabilities for short-term leases that have a lease term of 12 months or less. The Company has elected to apply the short-term lease recognition and measurement exemption allowed for in the lease accounting standard.  The Company recognizes the lease payments associated with its short-term leases as an expense on a straight-line basis over the lease term.

Lease cost for operating and finance leases for the three and nine months ended September 30, 2022 and 2021 were as follows:

Senior Notes

On March 9, 2022, the Company completed an underwritten public offering of $500,000 aggregate principal amount of 3.20% Senior Notes due 2032 (the “New 2032 Senior Notes”). The Company issued the New 2032 Senior Notes under the Indenture, dated as of November 16, 2018 (the “Base Indenture”), by and between the Company and U.S. Bank Trust Company, National Association, as successor in interest to U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by the Sixth Supplemental Indenture, dated as of March 9, 2022 (the “Sixth Supplemental Indenture”).  The New 2032 Senior Notes will mature on June 1, 2032.

The Company may, prior to March 1, 2032 (three months before the maturity date) (the “New 2032 Senior Notes Par Call Date”), redeem some or all of the New 2032 Senior Notes, at any time and from time to time, at a redemption price equal to the greater of 100% of the principal amount of the New 2032 Senior Notes redeemed, or the sum of the present values of the remaining scheduled payments of principal and interest on the New 2032 Senior Notes redeemed discounted to the redemption date (assuming the New 2032 Senior Notes matured on the New 2032 Senior Notes Par Call Date), plus, in either case, accrued and unpaid interest thereon to the redemption date. Commencing on March 1, 2032 (three months before the maturity date), the Company may redeem some or all of the New 2032 Senior Notes, at any time and from time to time, at a redemption price equal to the principal amount of the New 2032 Senior Notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

On August 18, 2022, the Company completed an underwritten public offering of $750,000 aggregate principal amount of 4.20% Senior Notes due 2033 (the “2033 Senior Notes” and, together with the New 2032 Senior Notes, the “Senior Notes”). The Company issued the 2033 Senior Notes under the Base Indenture, as supplemented by the Seventh Supplemental Indenture, dated as of August 18, 2022 (the “Seventh Supplemental Indenture” and the Base Indenture as supplemented by the Sixth Supplemental Indenture and the Seventh Supplemental Indenture, the “Indenture”).  The 2033 Senior Notes will mature on January 15, 2033.

The Company may, prior to October 15, 2032 (three months before the maturity date) (the “2033 Senior Notes Par Call Date”), redeem some or all of the 2033 Senior Notes, at any time and from time to time, at a redemption price equal to the greater of 100% of the principal amount of the 2033 Senior Notes redeemed, or the sum of the present values of the remaining scheduled payments of principal and interest on the 2033 Senior Notes redeemed discounted to the redemption date (assuming the 2033 Senior Notes matured on the 2033 Senior Notes Par Call Date), plus, in either case, accrued and unpaid interest thereon to the redemption date. Commencing on October 15, 2032 (three months before the maturity date), the Company may redeem some or all of the 2033 Senior Notes, at any time and from time to time, at a redemption price equal to the principal amount of the 2033 Senior Notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

The Company will pay interest on the Senior Notes semi-annually in arrears. The Senior Notes are the Company’s senior unsecured obligations, ranking equally in right of payment with its other existing and future unsubordinated debt and senior to any of its future subordinated debt. The Senior Notes are not guaranteed by any of the Company’s subsidiaries.

Under certain circumstances, the Company may become obligated to pay additional amounts (the “Additional Amounts”) with respect to the Senior Notes to ensure that the net amounts received by each holder of the Senior Notes will not be less than the amount such holder would have received if withholding taxes or deductions were not incurred on

a payment under or with respect to the Senior Notes. If such payment of Additional Amounts are a result of a change in the laws or regulations, including a change in any official position, the introduction of an official position or a holding by a court of competent jurisdiction, of any jurisdiction from or through which payment is made by or on behalf of the Senior Notes having power to tax, and the Company cannot avoid such payments of Additional Amounts through reasonable measures, then the Company may redeem the Senior Notes then outstanding at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date).

If the Company experiences certain kinds of changes of control, each holder of the Senior Notes may require the Company to repurchase all or a portion of the Senior Notes for cash at a price equal to 101% of the aggregate principal amount of such Senior Notes, plus any accrued and unpaid interest, if any, to, but excluding the purchase date.

The covenants in the Indenture include limitations on liens, sale-leaseback transactions and mergers and sales of all or substantially all of the Company’s assets. The Indenture also includes customary events of default with respect to the Senior Notes. As of September 30, 2022, the Company was in compliance with all applicable covenants in the Indenture.

Upon an event of default, the principal of and accrued and unpaid interest on all the Senior Notes may be declared to be due and payable by the Trustee or the holders of not less than 25% in principal amount of the outstanding Senior Notes. Upon such a declaration, such principal and accrued interest on all of the Senior Notes will be due and payable immediately. In the case of an event of default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding Senior Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holder of the Senior Notes. Under certain circumstances, the holders of a majority in principal amount of the outstanding Senior Notes may rescind any such acceleration with respect to the Senior Notes and its consequences.

Term Loan Agreement

On October 31, 2022 (the “Effective Date”), the Company, as borrower, Bank of America, N.A., as administrative agent, and the other lenders from time to time party thereto (the “New TL Lenders”) entered into that certain Term Loan Agreement (as amended, restated, supplemented or otherwise modified from time to time, the “Term Loan Agreement”), pursuant to which the New TL Lenders made loans to the Company in an aggregate stated principal amount of $800,000.  The Term Loan Agreement permits the proceeds of borrowings thereunder to be used for (i) refinancing outstanding indebtedness, (ii) financing permitted acquisitions and financing dividends or other permitted equity distributions, (iii) capital expenditures, working capital, payment of certain transaction fees, costs and expenses and (iv) any other lawful corporate purposes.  The Company intends to use substantially all of the proceeds of borrowings under the Term Loan Agreement to repay revolving borrowings outstanding under its Credit Agreement (as defined below) following the implementation of the Term Loan Agreement

Pursuant to the terms and conditions of the Term Loan Agreement, the New TL Lenders committed to provide the term loan as set forth above, which term loan was fully drawn as of the Effective Date.  Amounts borrowed under the Term Loan Agreement and repaid or prepaid may not be reborrowed.  The Term Loan Agreement has a scheduled maturity date of July 30, 2026.

Interest accrues on the term loan by reference to SOFR for specified interest periods (“Term SOFR”) (including for all Term SOFR loans, a credit spread adjustment of 0.10% for all applicable interest periods) or a base rate, at the Company’s option, plus an applicable margin.  The applicable margin used in connection with calculating interest rates and fees is based on the debt rating of the Company’s public non-credit-enhanced, senior unsecured long-term debt.  The

applicable margin for Term SOFR loans ranges from 0.750% to 1.250% per annum, and the applicable margin for base rate loans ranges from 0.00% to 0.250% per annum.

The Term Loan Agreement contains customary benchmark replacement mechanics in connection with certain benchmark transition events, as well as customary mechanics with respect to the unavailability of a tenor of a then-current benchmark rate. The borrowings under the Term Loan Agreement are unsecured and there are no subsidiary guarantors under the Term Loan Agreement.  

The Term Loan Agreement contains customary representations, warranties, covenants and events of default, including, among others, a change of control event of default and limitations on the incurrence of indebtedness and liens, new lines of business, mergers, transactions with affiliates and burdensome agreements. During the continuance of an event of default, the New TL Lenders may take a number of actions, including, among others, declaring the entire amount then outstanding under the Term Loan Agreement and related loan documents to be due and payable.

The Term Loan Agreement includes a financial covenant limiting, as of the last day of each fiscal quarter, the ratio of (i) Consolidated Total Funded Debt (as defined in the Term Loan Agreement) outstanding as of such date to (b) Consolidated EBITDA (as defined in the Term Loan Agreement), measured for the preceding 12 months, to not more than 3.75 to 1.00 (or 4.25 to 1.00 during material acquisition periods, subject to certain limitations).

Amendment No. 1 to Second Amended and Restated Revolving Credit and Term Loan Agreement

The Company is party to that certain Second Amended and Restated Revolving Credit and Term Loan Agreement, dated as of July 30, 2021 (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”), by and among the Company, as borrower, Bank of America, N.A., acting through its Canada Branch, as the global agent, the swing line lender and an l/c issuer, Bank of America, N.A., as the U.S. agent and an l/c issuer, and the lenders and any other financial institutions from time to time party thereto.

On the Effective Date, the Company entered into an amendment to the Credit Agreement (the “First Amendment”), which among other things, (i) amended certain definitions and other provisions to replace the LIBOR-based benchmark rates for certain U.S. dollar-denominated loans and other extensions of credit under the Credit Agreement with Term SOFR, and (ii) made certain changes conforming to the Term Loan Agreement.  The rates of interest payable by the Company per annum on its outstanding revolving loans immediately prior to the Effective Date did not materially change immediately after the Effective Date as a result of the replacement of LIBOR-based benchmark rates with Term SOFR.  In addition, because the replacement of LIBOR-based benchmark rates with Term SOFR was implemented through the First Amendment and not as a result of the hardwired benchmark replacement setting provisions of the Credit Agreement, the credit spread adjustment applicable to Term SOFR loans is a flat 0.10% per annum across all applicable interest periods instead of a varying credit spread adjustment across the same interest periods ranging from 0.11448% to 0.42826%.

Segment Reporting

11.SEGMENT REPORTING

The Company’s revenues are generated from the collection, transfer, recycling and disposal of non-hazardous solid waste and the treatment, recovery and disposal of non-hazardous E&P waste. No single contract or customer accounted for more than 10% of the Company’s total revenues at the consolidated or reportable segment level during the periods presented.

The Company manages its operations through the following five geographic solid waste operating segments: Eastern, Southern, Western, Central and Canada.  The Company’s five geographic solid waste operating segments comprise its

reportable segments.  Each operating segment is responsible for managing several vertically integrated operations, which are comprised of districts.  

The Company’s Chief Operating Decision Maker evaluates operating segment profitability and determines resource allocations based on several factors, of which the primary financial measure is segment EBITDA. The Company defines segment EBITDA as earnings before interest, taxes, depreciation, amortization, impairments and other operating items, and other income (expense). Segment EBITDA is not a measure of operating income, operating performance or liquidity under GAAP and may not be comparable to similarly titled measures reported by other companies. The Company’s management uses segment EBITDA in the evaluation of segment operating performance as it is a profit measure that is generally within the control of the operating segments. A reconciliation of segment EBITDA to Income before income tax provision is included at the end of this Note 11.

Summarized financial information concerning the Company’s reportable segments for the three and nine months ended September 30, 2022 and 2021, is shown in the following tables:

Derivative Financial Instruments

12.DERIVATIVE FINANCIAL INSTRUMENTS

The Company recognizes all derivatives on the Condensed Consolidated Balance Sheets at fair value. All of the Company’s derivatives have been designated as cash flow hedges; therefore, the gain or loss on the derivatives will be recognized in accumulated other comprehensive income (loss) (“AOCIL”) and reclassified into earnings in the same period during which the hedged transaction affects earnings and is presented in the same income statement line item as the earnings effect of the hedged item.  The Company classifies cash inflows and outflows from derivatives within operating activities on the Condensed Consolidated Statements of Cash Flows.

One of the Company’s objectives for utilizing derivative instruments is to reduce its exposure to fluctuations in cash flows due to changes in the variable interest rates of certain borrowings under the Credit Agreement. The Company’s strategy to achieve that objective involves entering into interest rate swaps. The interest rate swaps outstanding at September 30, 2022 were specifically designated to the Credit Agreement and accounted for as cash flow hedges.

At September 30, 2022, the Company’s derivative instruments included five interest rate swap agreements as follows:

			Fixed		Variable
	Notional		Interest		Interest Rate
Date Entered	Amount		Rate Paid*		Received	Effective Date	Expiration Date
August 2017	$	200,000	2.200	%	1-month LIBOR	October 2020	October 2025
August 2017	$	150,000	1.950	%	1-month LIBOR	February 2020	February 2023
June 2018	$	200,000	2.925	%	1-month LIBOR	October 2020	October 2025
June 2018	$	200,000	2.925	%	1-month LIBOR	October 2020	October 2025
December 2018	$	200,000	2.850	%	1-month LIBOR	July 2022	July 2027

The fair values of derivative instruments designated as cash flow hedges as of September 30, 2022, were as follows:

Derivatives Designated as Cash	Asset Derivatives			Liability Derivatives
Flow Hedges	Balance Sheet Location	Fair Value		Balance Sheet Location	Fair Value
Interest rate swaps	Prepaid expenses and other current assets(a)	$	14,000	Accrued liabilities	$	—

The actual amounts reclassified into earnings are dependent on future movements in interest rates.

The fair values of derivative instruments designated as cash flow hedges as of December 31, 2021, were as follows:

Derivatives Designated as Cash	Asset Derivatives			Liability Derivatives

____________________

(a)In accordance with the derivatives and hedging guidance, the changes in fair values of interest rate swaps have been recorded in equity as a component of AOCIL. As the critical terms of the interest rate swaps match the underlying debt being hedged, all unrealized changes in fair value are recorded in AOCIL.

(b)Amounts reclassified from AOCIL into earnings related to realized gains and losses on interest rate swaps are recognized when interest payments or receipts occur related to the swap contracts, which correspond to when interest payments are made on the Company’s hedged debt.

See Note 16 for further discussion on the impact of the Company’s hedge accounting to its consolidated comprehensive income (loss) and AOCIL.

Fair Value of Financial Instruments

13.FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company’s financial instruments consist primarily of cash and equivalents, trade receivables, restricted cash and investments, trade payables, debt instruments, contingent consideration obligations and interest rate swaps. As of September 30, 2022 and December 31, 2021, the carrying values of cash and equivalents, trade receivables, restricted cash and investments, trade payables and contingent consideration are considered to be representative of their respective fair values. The carrying values of the Company’s debt instruments, excluding certain notes as listed in the table below, approximate their fair values as of September 30, 2022 and December 31, 2021, based on current borrowing rates, current remaining average life to maturity and borrower credit quality for similar types of borrowing arrangements, and are classified as Level 2 within the fair value hierarchy. The carrying values and fair values of the Company’s debt instruments where the carrying values do not approximate their fair values as of September 30, 2022 and December 31, 2021, are as follows:

Fair Value Measurements

15.FAIR VALUE MEASUREMENTS

The Company uses a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis in periods subsequent to their initial measurement. These tiers include:  Level 1, defined as quoted market prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, model-based valuation techniques for which all significant assumptions are observable in the market, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3, defined as unobservable inputs that are not corroborated by market data.

The Company’s financial assets and liabilities recorded at fair value on a recurring basis include derivative instruments and restricted cash and investments. At September 30, 2022 and December 31, 2021, the Company’s derivative instruments included pay-fixed, receive-variable interest rate swaps. The Company’s interest rate swaps are recorded at their estimated fair values based on quotes received from financial institutions that trade these contracts. The Company verifies the reasonableness of these quotes using similar quotes from another financial institution as of each date for which financial statements are prepared. For the Company’s interest rate swaps, the Company also considers the Company’s creditworthiness in its determination of the fair value measurement of these instruments in a net liability position and the counterparties’ creditworthiness in its determination of the fair value measurement of these instruments in a net asset position. The Company’s restricted cash is valued at quoted market prices in active markets for identical assets, which the Company receives from the financial institutions that hold such investments on its behalf. The Company’s restricted cash measured at fair value is invested primarily in money market accounts, bank time deposits and U.S. government and agency securities. The Company’s restricted investments are valued at quoted market prices in active markets for similar assets, which the Company receives from the financial institutions that hold such investments on its behalf. The Company’s restricted investments measured at fair value are invested primarily in money market accounts, bank time deposits, U.S. government and agency securities and Canadian bankers’ acceptance notes.

The Company’s assets and liabilities measured at fair value on a recurring basis at September 30, 2022 and December 31, 2021, were as follows:

Employee Share Purchase Plan

On May 15, 2020, the Company’s shareholders approved the 2020 Employee Share Purchase Plan (the “ESPP”). Under the ESPP, qualified employees may elect to have payroll deductions withheld from their eligible compensation on

each payroll date in amounts equal to or greater than one percent (1%) but not in excess of ten percent (10%) of eligible compensation in order to purchase the Company’s common shares under certain terms and subject to certain restrictions set forth in the ESPP. The exercise price is equal to 95% of the closing price of the Company’s common shares on the last day of the relevant offering period, provided, however, that such exercise price will not be less than 85% of the volume weighted average price of the Company’s common shares as reflected on the Toronto Stock Exchange (the “TSX”) over the final five trading days of such offering period. The maximum number of shares that may be issued under the ESPP is 1,000,000.  Under the ESPP, employees purchased 26,582 of the Company’s common shares for $3,271 during the nine months ended September 30, 2022.

Normal Course Issuer Bid

On July 26, 2022, the Board of Directors of the Company approved, subject to receipt of regulatory approvals, the annual renewal of the Company’s normal course issuer bid (the “NCIB”) to purchase up to 12,859,066 of the Company’s common shares during the period of August 10, 2022 to August 9, 2023 or until such earlier time as the NCIB is completed or terminated at the option of the Company. The renewal followed the conclusion of the Company’s NCIB that expired August 9, 2022. The Company received TSX approval for its annual renewal of the NCIB on August 8, 2022.  Under the NCIB, the Company may make share repurchases only in the open market, including on the New York Stock Exchange (the “NYSE”), the TSX, and/or alternative Canadian trading systems, at the prevailing market price at the time of the transaction.

In accordance with TSX rules, any daily repurchases made through the TSX and alternative Canadian trading systems is limited to a maximum of 85,956 common shares, which represents 25% of the average daily trading volume on the TSX of 343,825 common shares for the period from February 1, 2022 to July 31, 2022. The TSX rules also allow the Company to purchase, once a week, a block of common shares not owned by any insiders, which may exceed such daily limit. The maximum number of shares that can be purchased per day on the NYSE will be 25% of the average daily trading volume for the four calendar weeks preceding the date of purchase, subject to certain exceptions for block purchases.

The timing and amounts of any repurchases pursuant to the NCIB will depend on many factors, including the Company’s capital structure, the market price of the common shares and overall market conditions. All common shares purchased under the NCIB shall be immediately cancelled following their repurchase.

For the nine months ended September 30, 2022, the Company repurchased 3,388,155 common shares pursuant to the NCIB in effect during that period at an aggregate cost of $424,999.  During the nine months ended September 30, 2021, the Company repurchased 2,745,990 common shares pursuant to the NCIB in effect during that period at an aggregate cost of $305,640.  As of September 30, 2022, the remaining maximum number of shares available for repurchase under the current NCIB was 12,859,066.

Cash Dividend

In October 2021, the Company announced that its Board of Directors increased its regular quarterly cash dividend by $0.025, from $0.205 to $0.23 per Company common share. Cash dividends of $177,710 and $160,754 were paid during the nine months ended September 30, 2022 and 2021, respectively.

18.COMMITMENTS AND CONTINGENCIES

In the normal course of its business and as a result of the extensive governmental regulation of the solid waste and E&P waste industries, the Company is subject to various judicial and administrative proceedings involving Canadian regulatory authorities as well as U.S. federal, state and local agencies. In these proceedings, an agency may subpoena the

Company for records, or seek to impose fines on the Company or revoke or deny renewal of an authorization held by the Company, including an operating permit. From time to time, the Company may also be subject to actions brought by special interest or other groups, adjacent landowners or residents in connection with the permitting and licensing of landfills, transfer stations, and E&P waste treatment, recovery and disposal operations, or alleging environmental damage or violations of the permits and licenses pursuant to which the Company operates. The Company uses $1,000 as a threshold (up from the previously required threshold of $300) for disclosing environmental matters involving potential monetary sanctions.

In addition, the Company is a party to various claims and suits pending for alleged damages to persons and property, alleged violations of certain laws and alleged liabilities arising out of matters occurring during the normal operation of the Company’s business. Except as noted in the matters described below, as of September 30, 2022, there is no current proceeding or litigation involving the Company or its property that the Company believes could have a material adverse effect on its business, financial condition, results of operations or cash flows.

Los Angeles County, California Landfill Expansion Litigation

A. Chiquita Canyon, LLC Lawsuit Against Los Angeles County

In October 2004, the Company’s subsidiary, Chiquita Canyon, LLC (“CCL”), then under prior ownership, filed an application (the “Application”) with the County of Los Angeles (the “County”) Department of Regional Planning (“DRP”) for a conditional use permit (the “CUP”) to authorize the continued operation and expansion of the Chiquita Canyon Landfill (the “Landfill”). The Landfill has operated since 1972, and as a regional landfill, accepted approximately two and a half million tons of materials for disposal and beneficial use in 2021.  The Application requested expansion of the existing waste footprint on CCL’s contiguous property, an increase in maximum elevation, creation of a new entrance and new support facilities, construction of a facility for the County or another third-party operator to host household hazardous waste collection events, designation of an area for mixed organics/composting, and other modifications.

After many years of reviews and delays, upon the recommendation of County staff, the County’s Regional Planning Commission (the “Commission”) approved the Application on April 19, 2017, but imposed operating conditions, fees and exactions that substantially reduce the historical landfill operations and represent a large increase in aggregate taxes and fees. CCL objected to many of the requirements imposed by the Commission.  Current estimates for new costs imposed on CCL under the CUP are in excess of $300,000.

CCL appealed the Commission’s decision to the County Board of Supervisors, but the appeal was not successful.  At a subsequent hearing, on July 25, 2017, the Board of Supervisors approved the CUP.  On October 20, 2017, CCL filed in the Superior Court of California, County of Los Angeles a verified petition for writ of mandate and complaint against the County and the County Board of Supervisors captioned Chiquita Canyon, LLC v. County of Los Angeles, No. BS171262 (Los Angeles Co. Super Ct.) (the “Complaint”).  The Complaint challenges the terms of the CUP in 13 counts generally alleging that the County violated multiple California and federal statutes and California and federal constitutional protections. CCL seeks the following relief: (a) an injunction and writ of mandate against certain of the CUP’s operational restrictions, taxes and fees, (b) a declaration that the challenged conditions are unconstitutional and in violation of state and federal statutes, (c) reimbursement for any such illegal fees paid under protest, (d) damages, (e) an award of just compensation for a taking, (f) attorney fees, and (g) all other appropriate legal and equitable relief.

Following extensive litigation in 2018 and 2019 on the permissible scope of CCL’s challenge, full briefing occurred, and oral argument was held on June 22, 2020 on six of CCL’s causes of action. The Superior Court issued its decision on July 2, 2020, granting CCL’s petition for writ of mandate in part and denying it in part. CCL prevailed with respect to 12 of the challenged conditions, many of which imposed new fees and exactions on the Landfill.  On October 11, 2022, CCL

and the County entered into a settlement agreement that requires Chiquita to file a CUP modification application with the County embodying the terms of the settlement agreement.  If the CUP modification application is approved by the County and certain other contingencies are satisfied, Chiquita will dismiss this lawsuit.  However, at this point, the Company is not able to determine the likelihood of any outcome in this matter.

B. December 11, 2017 Notice of Violation Regarding Certain CUP Conditions.

The County, through its DRP, issued a Notice of Violation, dated December 11, 2017 (the “NOV”), alleging that CCL violated certain conditions of the CUP, including Condition 79(B)(6) of the CUP by failing to pay an $11,600 Bridge & Thoroughfare Fee (“B&T Fee”) that was purportedly due on July 25, 2017.  The alleged B&T fee was ostensibly to fund the construction of transportation infrastructure in the area of the Landfill.  At the time the NOV was issued, CCL had already contested the legality of the B&T fee in the October 20, 2017 Complaint filed against the County in Los Angeles County Superior Court, described above under paragraph A (the “CUP lawsuit”).

On January 12, 2018, CCL filed an appeal of the alleged violations in the NOV.  Subsequently, CCL filed additional legal arguments and exhibits contesting the NOV.  On March 6, 2018, a DRP employee designated as hearing officer sustained the NOV, including the $11,600 B&T fee, and imposed an administrative penalty in the amount of $83 and a noncompliance fee of $0.75. A written decision memorializing the hearing officer’s findings and order was issued on July 10, 2018.  On April 13, 2018, CCL filed in the Superior Court of California, County of Los Angeles a Petition for Writ of Administrative Mandamus against the County seeking to overturn the decision sustaining the NOV, contending that the NOV and decision are not supported by the facts or law.  On July 17, 2018, the Court granted CCL leave to pay the $11,600 B&T fee and to amend its Complaint in the CUP lawsuit to reflect the payment under protest, allowing the challenge to the B&T fee under the Mitigation Fee Act to proceed in the CUP lawsuit.  CCL paid the B&T fee under protest on August 10, 2018, and also paid on that date the administrative penalty of $83 and a noncompliance fee of $0.75. The Court indicated that the NOV case would be coordinated with the CUP lawsuit.  On October 11, 2022, CCL and the County entered into a settlement agreement, described above under paragraph A.  If the CUP modification application is approved by the County and certain other contingencies are satisfied, Chiquita will dismiss this lawsuit.  However, at this point, the Company is not able to determine the likelihood of any outcome in this matter.

Leases (Policy)

9 Months Ended

Sep. 30, 2022

Lessee Disclosure [Abstract]

Leases

The Company rents certain equipment and facilities under short-term agreements, non-cancelable operating lease agreements and finance leases.  The Company determines if an arrangement is or contains a lease at contract inception. The Company recognizes a right-of-use (“ROU”) asset and a lease liability at the lease commencement date.  The lease liability is initially measured at the present value of the unpaid lease payments at the lease commencement date.

Key estimates and judgments include how the Company determines (1) the discount rate it uses to discount the unpaid lease payments to present value, (2) lease term and (3) lease payments.

The lease guidance requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. Generally, the Company cannot determine the interest rate implicit in the lease because it does not have access to the lessor’s estimated residual value or the amount of the lessor’s deferred initial direct costs.  Therefore, the Company generally uses its incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms.

The lease term for the Company’s leases includes the noncancelable period of the lease, plus any additional periods covered by either a Company option to extend (or not to terminate) the lease that the Company is reasonably certain to exercise, or an option to extend (or not to terminate) the lease controlled by the lessor.

Lease payments included in the measurement of the lease liability comprise fixed payments or variable lease payments.  The variable lease payments take into account annual changes in the consumer price index and common area maintenance charges, if known.

ROU assets for operating and finance leases are periodically reviewed for impairment losses. The Company uses the long-lived asset impairment guidance in ASC Subtopic 360-10, Property, Plant, and Equipment – Overall, to determine whether an ROU asset is impaired, and if so, the amount of the impairment loss to recognize.  The Company did not recognize an impairment charge for any of its ROU assets during the nine months ended September 30, 2022 and 2021.

The Company monitors for events or changes in circumstances that require a reassessment of one of its leases. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the corresponding ROU asset.  The Company did not recognize any significant remeasurements during the nine months ended September 30, 2022 and 2021.

The Company has elected not to recognize ROU assets and lease liabilities for short-term leases that have a lease term of 12 months or less. The Company has elected to apply the short-term lease recognition and measurement exemption allowed for in the lease accounting standard.  The Company recognizes the lease payments associated with its short-term leases as an expense on a straight-line basis over the lease term.

____________________

(a)In accordance with the derivatives and hedging guidance, the changes in fair values of interest rate swaps have been recorded in equity as a component of AOCIL. As the critical terms of the interest rate swaps match the underlying debt being hedged, all unrealized changes in fair value are recorded in AOCIL.

(b)Amounts reclassified from AOCIL into earnings related to realized gains and losses on interest rate swaps are recognized when interest payments or receipts occur related to the swap contracts, which correspond to when interest payments are made on the Company’s hedged debt.

As the critical terms of the interest rate swaps match the underlying debt being hedged, all unrealized changes in fair value are recorded in AOCIL.
