NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

Republic Services, Inc., a Delaware corporation, and its consolidated subsidiaries (also referred to collectively as Republic, the Company, we, us, or our), is the second largest provider of non-hazardous solid waste collection, transfer, recycling, disposal and environmental services in the United States, as measured by revenue. We manage and evaluate our operations through two field groups, Group 1 and Group 2, which we have identified as our reportable segments.

The unaudited consolidated financial statements include the accounts of Republic Services, Inc. and its wholly owned and majority owned subsidiaries in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). We account for investments in entities in which we do not have a controlling financial interest under either the equity method or cost method of accounting, as appropriate. All material intercompany accounts and transactions have been eliminated in consolidation.

We have prepared these unaudited consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information related to our organization, significant accounting policies and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP has been condensed or omitted. In the opinion of management, these financial statements include all adjustments that, unless otherwise disclosed, are of a normal recurring nature and necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented. Operating results for interim periods are not necessarily indicative of the results you can expect for a full year. You should read these financial statements in conjunction with our audited consolidated financial statements and notes thereto appearing in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

For comparative purposes, certain prior year amounts have been reclassified to conform to the current year presentation. All dollar amounts in tabular presentations are in millions, except per share amounts and unless otherwise noted.

Management’s Estimates and Assumptions

In preparing our financial statements, we make numerous estimates and assumptions that affect the amounts reported in these financial statements and accompanying notes. We must make these estimates and assumptions because certain information we use is dependent on future events, cannot be calculated with a high degree of precision from data available or simply cannot be readily calculated based on generally accepted methodologies. In preparing our financial statements, the more critical and subjective areas that deal with the greatest amount of uncertainty relate to our accounting for our long-lived assets, including recoverability, development costs, and final capping, closure and post-closure costs; our valuation allowances for accounts receivable and deferred tax assets; our liabilities for potential litigation, claims and assessments; our liabilities for environmental remediation, multiemployer pension funds, employee benefit plans, deferred taxes, uncertain tax positions, and insurance reserves; and our estimates of the fair values of assets acquired and liabilities assumed in any acquisition. Each of these items is discussed in more detail in our description of our significant accounting policies in Note 2, Summary of Significant Accounting Policies, of the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018. Our actual results may differ significantly from our estimates.

New Accounting Pronouncements

Accounting Standards Adopted

Effective January 1, 2019, we adopted the following accounting standard updates (ASUs) as issued by the Financial Accounting Standards Board (FASB):

ASU		Effective Date
ASU 2016-02	Leases (Topic 842)	January 1, 2019
ASU 2017-12	Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities	January 1, 2019
ASU 2018-16	Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting	January 1, 2019
ASU 2018-02	Income Statement - Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income	January 1, 2019
ASU 2018-07	Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting	January 1, 2019
ASU 2018-15	Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract	January 1, 2019

Leases

Effective January 1, 2019, we adopted ASU 2016-02, Leases (Topic 842) (ASC 842 or the new leasing standard) using the optional transition method prescribed by ASU 2018-11, Leases (Topic 842): Targeted Improvements. Upon adoption of the new leasing standard, we recognized a right-of-use asset and a right-of-use liability for leases classified as operating leases in our consolidated balance sheet. We applied the package of practical expedients to leases that commenced before the effective date whereby we elected to not reassess the following: (i) whether any expired or existing contracts contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases.

To assist in quantifying the impact on our consolidated financial statements and supplementing our existing disclosures, we designed internal controls over the adoption and implemented a software solution to manage and account for our leases. As of January 1, 2019, we recognized a right-of-use liability for our operating leases of $256.3 million classified as other accrued liabilities and other long-term liabilities and a corresponding right-of-use asset of $236.2 million classified as other long-term assets in our consolidated balance sheet. The right-of-use asset reflects adjustments for certain favorable or unfavorable leases recognized through acquisitions, prepaid or accrued rent, asset impairments and lease incentives, including but not limited to cash incentives, rent abatement or leasehold improvements paid by the lessor. We did not recognize a cumulative effect adjustment to retained earnings as of January 1, 2019 as the standard did not have a material impact on our consolidated statement of income. In addition, the standard did not have a material impact on our accounting for finance (capital) leases.

We assessed the disclosure requirements under the new leasing standard as part of our adoption. Refer to Note 4, Other Assets, Note 5, Other Liabilities, and Note 8, Leases, included herein for our enhanced supplemental disclosures.

Derivatives and Hedging

Effective January 1, 2019, we adopted the FASB's ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (ASU 2017-12). We adopted the new guidance over income statement presentation and enhanced disclosures prospectively, and we adopted the guidance over the elimination of the separate measurement of ineffectiveness on a modified retrospective basis to existing hedging relationships as of the date of adoption. Prior to adoption, the net periodic earnings of our fair value hedges were presented within other income, net in our consolidated statement of income and are now presented within interest expense in our consolidated statement of income, i.e. the same line item as the effect of the hedged item. Our adoption of ASU 2017-12 did not have a material impact on our consolidated financial statements.

Effective January 1, 2019, in conjunction with ASU 2017-12, we adopted the FASB's ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting (ASU 2018-16) on a prospective basis. LIBOR is expected to no longer be published by 2021. Consequently, the FASB added the OIS rate based on SOFR as an eligible benchmark interest rate in order to facilitate the LIBOR to SOFR transition and provide sufficient lead time for entities to prepare for changes to interest rate risk hedging strategies for both risk management and hedge accounting purposes. We are developing a plan to transition our interest rate

swaps from LIBOR to SOFR. Our adoption of ASU 2018-16 did not have a material impact on our consolidated financial statements for the nine months ended September 30, 2019.

Reclassifications of Certain Tax Effects from Accumulated Other Comprehensive Income

Effective January 1, 2019, we adopted the FASB's ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (ASU 2018-02). The amendments eliminate the stranded tax effects resulting from the Tax Cuts and Jobs Act (the Tax Act). The amendments only relate to the reclassification of the income tax effects of the Tax Act, and the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. Consequently, we reclassified $5.4 million of stranded tax effects from accumulated other comprehensive income to retained earnings.

Improvements to Nonemployee Share-Based Payment Accounting

Effective January 1, 2019, we adopted the FASB's ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (ASU 2018-07). ASU 2018-07 simplifies several aspects of the accounting for nonemployee share-based payment transactions resulting from expanding the scope of Topic 718, Compensation - Stock Compensation, to include share-based payment transactions for acquiring goods and services from nonemployees. We will apply the guidance prescribed by this update on a prospective basis. Our adoption of ASU 2018-07 did not have a material impact on our consolidated financial statements for the nine months ended September 30, 2019.

Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract

Effective January 1, 2019, we early adopted the FASB's ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) No. 2018-15 Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (ASU 2018-15) using a prospective approach. In accordance with the standard, we present capitalized implementation costs incurred in a hosting arrangement that is a service contract as other assets on our consolidated balance sheet. This presentation is consistent with the presentation of the prepayment of fees for the hosting arrangement. Historically, implementation costs were presented as a component of property and equipment, net.

As of January 1, 2019, we reclassified $28.7 million of capitalized implementation costs incurred in a hosting arrangement that is a service contract from property and equipment, net to other assets on our consolidated balance sheet. During the three and nine months ended September 30, 2019, we recognized $9.0 million and $25.3 million, respectively, of amortization expense for the prepayment of fees and capitalized implementation costs incurred in a hosting arrangement as a component of depreciation, amortization and depletion in our consolidated statement of income. During the nine months ended September 30, 2019, we recognized $9.0 million of payments for capitalized implementation costs in the same manner as payments made for fees associated with the hosting arrangement as a component of cash provided by operating activities in our consolidated statement of cash flows.

Accounting Standards Issued but not yet Adopted

Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. ASU 2016-13 will replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 is effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. We are currently assessing the effect this guidance may have on our consolidated financial statements.

Changes to the Disclosure Requirements for Fair Value Measurement

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13). ASU 2018-13 modifies the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. ASU 2018-13 is effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. We are currently assessing the effect this guidance may have on our consolidated financial statements.

Changes to the Disclosure Requirements for Defined Benefit Plans

In August 2018, the FASB issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20) Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans (ASU 2018-14). ASU 2018-14 removes disclosures that no longer are considered cost beneficial, clarifies the specific requirements of disclosures, and adds disclosure requirements identified as relevant. Although narrow in scope, the amendments are considered an important part of the FASB’s efforts to improve the effectiveness of disclosures in the notes to financial statements. ASU 2018-14 is effective for public business entities for fiscal years beginning after December 15, 2020, including interim periods within that fiscal year. Early adoption is permitted for all entities. We are currently assessing the effect this guidance may have on our consolidated financial statements.

We are finalizing the valuation of tangible and intangible assets for certain acquisitions that closed during the three months ended September 30, 2019.

Substantially all of the goodwill and intangible assets recorded for these acquisitions are deductible for tax purposes. These acquisitions are not material to our results of operations, individually or in the aggregate. As a result, no pro forma financial information is provided.

Investments

In 2019 and 2018, we acquired non-controlling equity interests in certain limited liability companies that qualified for investment tax credits under Section 48 of the Internal Revenue Code. In exchange for our non-controlling interests, we made certain capital contributions of $14.1 million and $17.4 million, which were recorded to other assets in our September 30, 2019

and 2018 consolidated balance sheets, respectively. During the nine months ended September 30, 2019 and 2018, we also reduced the carrying value of these investments by $27.2 million and $5.7 million, respectively, as a result of tax credits allocated to us, cash distributions and our share of income and loss pursuant to the terms of the limited liability company agreements.

Restructuring Charges

In January 2018, we eliminated certain positions following the consolidation of select back-office functions, including but not limited to the integration of our National Accounts support functions into our existing corporate support functions. These changes include a reduction in administrative staffing and closing of certain office locations.

During the three and nine months ended September 30, 2019, we incurred restructuring charges of $8.5 million and $13.0 million, respectively, that primarily related to upgrades to our back-office software systems. During the three and nine months ended September 30, 2018, we incurred restructuring charges of $9.2 million and $22.5 million, respectively, that primarily consisted of severance and other employee termination benefits and the closure of offices with lease agreements with non-cancelable terms. We paid $7.9 million and $18.7 million during the nine months ended September 30, 2019 and 2018, respectively, related to these restructuring efforts.

In 2019, we expect to incur additional restructuring charges of approximately $3 million to $5 million primarily related to upgrades to our back-office software systems. Substantially all of these restructuring charges will be recorded in our corporate segment.

6. LANDFILL AND ENVIRONMENTAL COSTS

As of September 30, 2019, we owned or operated 190 active landfills with total available disposal capacity of approximately 5.0 billion in-place cubic yards. Additionally, we have post-closure responsibility for 129 closed landfills.

Final Capping, Closure and Post-Closure Costs

The following table summarizes the activity in our asset retirement obligation liabilities, which includes liabilities for final capping, closure and post-closure, for the nine months ended September 30, 2019 and 2018:

	2019		2018
Asset retirement obligation liabilities, beginning of year	$	1,292.0	$	1,257.7
Non-cash additions	32.9		33.0
Acquisitions, net of divestitures and other adjustments	0.3		(0.6)
Asset retirement obligation adjustments	0.7		(18.4)
Payments	(47.7)		(42.5)
Accretion expense	61.4		60.7
Asset retirement obligation liabilities, end of period	1,339.6		1,289.9
Less: current portion	(80.9)		(94.2)
Long-term portion	$	1,258.7	$	1,195.7

We review annually, in the fourth quarter, and update as necessary, our estimates of asset retirement obligation liabilities. However, if there are significant changes in the facts and circumstances related to a site during the year, we will update our assumptions prospectively in the period that we know all the relevant facts and circumstances and make adjustments as appropriate.

The fair value of assets that are legally restricted for purposes of settling final capping, closure and post-closure liabilities was $30.4 million and $29.5 million as of September 30, 2019 and December 31, 2018, respectively, and is included in restricted cash and marketable securities in our consolidated balance sheets.

Landfill Operating Expenses

In the normal course of business, we incur various operating costs associated with environmental compliance. These costs include, among other things, leachate treatment and disposal, methane gas and groundwater monitoring, systems maintenance, interim cap maintenance, costs associated with the application of daily cover materials, and the legal and administrative costs of ongoing environmental compliance. These costs are expensed as cost of operations in the periods in which they are incurred.

Environmental Remediation Liabilities

We accrue for remediation costs when they become probable and can be reasonably estimated. There can sometimes be a range of reasonable estimates of the costs associated with remediation of a site. In these cases, we use the amount within the range that constitutes our best estimate. If no amount within the range appears to be a better estimate than any other, we use the amount that is at the low end of the range. It is reasonably possible that we will need to adjust the liabilities recorded for remediation to reflect the effects of new or additional information, to the extent such information impacts the costs, timing or duration of the required actions. If we used the reasonably possible high ends of our ranges, our aggregate potential remediation liability as of September 30, 2019 would be approximately $369 million higher than the amount recorded. Future changes in our estimates of the cost, timing or duration of the required actions could have a material adverse effect on our consolidated financial position, results of operations and cash flows.

The following table summarizes the activity in our environmental remediation liabilities for the nine months ended September 30, 2019 and 2018:

	2019		2018
Environmental remediation liabilities, beginning of year	$	540.2	$	564.0
Net adjustments charged to expense	(9.6)		3.3
Payments	(29.4)		(30.2)
Accretion expense (non-cash interest expense)	14.3		15.2
Acquisitions, net of divestitures and other adjustments	0.1		—
Environmental remediation liabilities, end of period	515.6		552.3

Bridgeton Landfill. During the nine months ended September 30, 2019, we paid $12.0 million related to management and monitoring of the remediation area for our closed Bridgeton Landfill in Missouri. We continue to work with state and federal regulatory agencies on our remediation efforts. From time to time, this may require us to modify our future operating timeline and procedures, which could result in changes to our expected liability. As of September 30, 2019, the remediation liability recorded for this site was $149.1 million, of which approximately $2 million is expected to be paid during the remainder of 2019. We believe the remaining reasonably possible high end of our range would be approximately $171 million higher than the amount recorded as of September 30, 2019.

West Lake Landfill Superfund Site. Our subsidiary Bridgeton Landfill, LLC is one of several currently designated Potentially Responsible Parties for the West Lake Landfill Superfund site (West Lake) in Missouri. On September 27, 2018, the U.S. Environmental Protection Agency (EPA) issued a Record of Decision Amendment for West Lake that includes a total undiscounted cost estimate of $229 million over a four- to five-year design and construction timeline. On March 11, 2019, the EPA issued special notice letters under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA) to Bridgeton Landfill, LLC and the other currently designated Potentially Responsible Parties to initiate negotiations to implement the remedy. At this time we are neither able to predict the final design of that remedy, nor estimate how much of the future response costs of the site our subsidiary may agree or be required to pay. During any subsequent administrative proceedings or litigation, our subsidiary will vigorously contest liability for the costs of remediating radiologically-impacted materials generated on behalf of the federal government during the Manhattan Project and delivered to the site by an Atomic Energy Commission licensee and its subcontractor. Currently, we believe we are adequately reserved for our expected remediation liability. However, subsequent events related to remedy design, divisibility, or allocation may require us to modify our expected remediation liability.

In June 2018, we entered into a $2.25 billion unsecured revolving credit facility (the Credit Facility), which replaced our $1.0 billion and $1.25 billion unsecured credit facilities that would have matured in May 2021 and June 2019, respectively. The Credit Facility matures in June 2023. We may request two one-year extensions of the maturity date but none of the lenders are committed to participate in such extension. The Credit Facility also includes a feature that allows us to increase availability, at our option, by an aggregate amount of up to $1.0 billion through increased commitments from existing lenders or the addition of new lenders. At our option, borrowings under the Credit Facility bear interest at a Base Rate, or a Eurodollar Rate, plus an applicable margin based on our Debt Ratings (all as defined in the Credit Facility agreement).

The Credit Facility is subject to facility fees based on applicable rates defined in the Credit Facility agreement and the aggregate commitment, regardless of usage. Availability under our Credit Facility totaled $1,710.6 million and $1,694.1 million

as of September 30, 2019 and December 31, 2018, respectively. The Credit Facility can be used for working capital, capital expenditures, acquisitions, letters of credit and other general corporate purposes. The Credit Facility agreement requires us to comply with financial and other covenants. We may pay dividends and repurchase common stock if we are in compliance with these covenants.

As of September 30, 2019 and December 31, 2018, we had $170.0 million and $159.0 million of borrowings under our Credit Facility, respectively. We had $352.0 million and $379.6 million of letters of credit outstanding under our Credit Facility as of September 30, 2019 and December 31, 2018, respectively.

We also have an Uncommitted Credit Facility, which bears interest at LIBOR, plus an applicable margin and is subject to facility fees defined in the agreement, regardless of usage. We can use borrowings under the Uncommitted Credit Facility for working capital and other general corporate purposes. The agreement governing our Uncommitted Credit Facility requires us to comply with certain covenants. The Uncommitted Credit Facility may be terminated by either party at any time. We had $12.2 million of borrowings and $33.4 million of borrowings outstanding under our Uncommitted Credit Facility as of September 30, 2019 and December 31, 2018, respectively.

Senior Notes and Debentures

In August 2019, we issued $900.0 million of 2.500% senior notes due 2024 (the 2.500% Notes). We used the net proceeds from the 2.500% Notes to repay $650.0 million of 5.500% senior notes that matured in September 2019. Any remaining proceeds were used to repay amounts outstanding under our unsecured credit facilities as well as for general corporate purposes. Contemporaneously with this offering, we amended interest rate lock agreements with a notional value of $375.0 million and dedesignated the hedging relationship. There was no ineffectiveness recognized in the termination of these cash flow hedges. In addition, we entered into an offsetting interest rate swap to manage exposure to fluctuations in interest rates associated with the amended agreements. For further detail regarding the effect of our derivative contracts on interest expense, refer to Note 12, Financial Instruments, to our unaudited consolidated financial statements in Item 1 of Part I of this Quarterly Report on Form 10-Q.

In 2018, we issued $800.0 million of 3.950% senior notes due 2028 (the 3.950% Notes). We used the net proceeds from the 3.950% Notes to repay $700.0 million of 3.800% senior notes that matured in May 2018, and any remaining proceeds were used for general corporate purposes. In connection with this offering, we terminated interest rate lock agreements with a notional value of $600.0 million, resulting in net proceeds of $31.1 million. There was no ineffectiveness recognized in the termination of these cash flow hedges.

Our senior notes and debentures are general unsecured obligations. Interest is payable semi-annually.

Tax-Exempt Financings

During the second quarter of 2019, we refinanced $35.0 million of tax-exempt financings and issued $30.0 million of new tax-exempt financings. As of September 30, 2019, we had $1,066.3 million of certain variable rate tax-exempt financings outstanding with maturities ranging from 2020 to 2049. As of December 31, 2018, we had $1,036.8 million of certain variable rate tax-exempt financings outstanding with maturities ranging from 2019 to 2044. Approximately 100% of our tax-exempt financings are remarketed quarterly by remarketing agents to effectively maintain a variable yield. The holders of the bonds can put them back to the remarketing agents at the end of each interest period. To date, the remarketing agents have been able to remarket all of our variable rate unsecured tax-exempt bonds.

Finance Leases

We had finance lease liabilities of $112.4 million and $109.5 million as of September 30, 2019 and December 31, 2018, respectively, with maturities ranging from 2019 to 2049 and 2019 to 2046, respectively.

Interest Rate Swap and Lock Agreements

Our ability to obtain financing through the capital markets is a key component of our financial strategy. Historically, we have managed risk associated with executing this strategy, particularly as it relates to fluctuations in interest rates, by using a combination of fixed and floating rate debt. From time to time, we also have entered into interest rate swap and lock agreements to manage risk associated with interest rates, either to effectively convert specific fixed rate debt to a floating rate (fair value hedges), or to lock interest rates in anticipation of future debt issuances (cash flow hedges).

Fair Value Hedges

During the second half of 2013, we entered into various interest rate swap agreements relative to our 4.750% fixed rate senior notes due in May 2023. The goal was to reduce overall borrowing costs and rebalance our debt portfolio's ratio of fixed to floating interest rates. As of September 30, 2019 and December 31, 2018, these swap agreements had a total notional value of $300.0 million and mature in May 2023, which is identical to the maturity of the hedged senior notes. We pay interest at floating rates based on changes in LIBOR and receive interest at a fixed rate of 4.750%. These transactions were designated as fair value hedges because the swaps hedge against the changes in fair value of the fixed rate senior notes resulting from changes in interest rates.

As of September 30, 2019 and December 31, 2018, the interest rate swap agreements are reflected at their fair value of $13.1 million and $2.5 million, respectively, and are included in other assets in our consolidated balance sheet. To the extent they are effective, these interest rate swap agreements are included as an adjustment to long-term debt in our consolidated balance sheets.

For the three months ended September 30, 2019 and 2018, we recognized a loss of $1.1 million and a gain of $1.9 million, respectively, on the change in fair value of the hedged senior notes attributable to changes in the benchmark interest rate, with an offsetting gain of $1.4 million and an offsetting loss of $2.0 million, respectively, on the related interest rate swaps. For the nine months ended September 30, 2019 and 2018, we recognized a loss of $10.0 million and a gain of $11.1 million, respectively, on the change in fair value of the hedged senior notes attributable to changes in the benchmark interest rate, with an offsetting gain of $10.5 million and an offsetting loss of $11.5 million, respectively, on the related interest rate swaps. The difference of these fair value changes for the nine months ended September 30, 2018 was recorded directly in earnings as other income, net. In accordance with our adoption of ASU 2017-12, the difference of these fair value changes for the nine months ended September 30, 2019 was recorded directly in earnings as an adjustment to interest expense in our consolidated statement of income.

For further detail regarding the effect of our fair value hedging on interest expense, refer to Note 12, Financial Instruments, to our unaudited consolidated financial statements in Item 1 of Part I of this Quarterly Report on Form 10-Q.

Cash Flow Hedges

As of September 30, 2019 and December 31, 2018, our interest rate lock agreements had an aggregate notional value of $575.0 million and $725.0 million, respectively, with fixed interest rates ranging from 1.330% to 3.000% and 1.900% to 3.250%, respectively. We entered into these transactions to manage exposure to fluctuations in interest rates in anticipation of planned future issuances of senior notes in 2019 through 2021. Upon the expected issuance of senior notes, we will terminate the interest rate locks and settle with our counterparties. These transactions were accounted for as cash flow hedges.

The fair value of our interest rate locks was determined using standard valuation models with assumptions about interest rates being based on those observed in underlying markets (Level 2 in the fair value hierarchy). The aggregate fair values of the outstanding interest rate locks as of September 30, 2019 were assets of $1.3 million, which were recorded in prepaid expenses and other current assets in our consolidated balance sheet and liabilities of $30.7 million, which were recorded in other accrued liabilities and other long-term liabilities in our consolidated balance sheet. As of December 31, 2018, the aggregate fair values of the outstanding interest rate locks were assets of $10.3 million and were recorded in other assets in our consolidated balance sheet.

Total unrealized (loss) gain recognized in other comprehensive income for interest rate locks was $(11.9) million and $4.2 million for the three months ended September 30, 2019 and 2018, respectively. Total unrealized (loss) gain recognized in other comprehensive income for interest rate locks was $(43.0) million and $33.1 million for the nine months ended September 30, 2019 and 2018, respectively.

As of September 30, 2019 and December 31, 2018, our previously terminated interest rate locks were recorded as components of accumulated other comprehensive income (loss), net of tax of $(3.5) million and $11.2 million, respectively. The amortization of the terminated interest rate locks is recorded as an adjustment to interest expense over the life of the issued debt using the effective interest method. We expect to amortize approximately $1.9 million of net interest expense, net of tax, over the next 12 months as a yield adjustment of our senior notes.

For detail regarding the effect of our cash flow hedging on interest expense, refer to Note 12, Financial Instruments, to our unaudited consolidated financial statements in Item 1 of Part I of this Quarterly Report on Form 10-Q.

8. LEASES

We lease property and equipment in the ordinary course of business under various lease agreements. The most significant lease obligations are for real property and equipment specific to our industry, including property operated as a landfill or transfer

20

REPUBLIC SERVICES, INC.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

station and operating equipment. Our leases have varying terms. Some may include renewal or purchase options, escalation clauses, restrictions, penalties or other obligations that we consider in determining minimum lease payments. Our lease terms include options to renew the lease when it is reasonably certain that we will exercise the option.

Certain leases require payments that are variable in nature based on volume measurements, e.g. a fixed rate per ton at our landfills. In addition, certain rental payments are adjusted annually based on changes in an underlying base index such as a consumer price index. Variable lease payments are recognized in our consolidated statement of income in the period incurred. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. We generally account for lease components separately from non-lease components.

Leases are classified as either operating leases or finance leases, as appropriate. Leases with an initial term of 12 months or less are not recorded on our consolidated balance sheet.

Operating Leases

Many of our leases are operating leases. Operating lease classification generally can be attributed to either (1) relatively low fixed minimum lease payments (including, for example, real property lease payments that are not fixed and vary based on the volume of waste we receive or process), or (2) minimum lease terms that are shorter than the asset's economic useful life. We expect that, in the ordinary course of business, our operating leases will be renewed, replaced by other leases, or replaced with capital expenditures. We recognize rent expense for these leases on a straight-line basis over the lease term.

We recognize a right-of-use liability and right-of-use asset for leases classified as operating leases in our consolidated balance sheet upon lease commencement. The right-of-use liability represents the present value of the remaining lease payments. An implicit rate is often not readily available for these leases. As such, we use our incremental borrowing rate at the commencement date to determine the present value of the lease payments. Our incremental borrowing rate represents the rate of interest that we would have to pay to borrow on a collateralized basis over a similar term in a similar economic environment. In addition, we recognize a corresponding right-of-use asset, which represents our right to use an underlying asset for the lease term. The right-of-use asset is adjusted for certain favorable or unfavorable leases recognized through acquisition, prepaid or accrued rent, asset impairments and lease incentives, including but not limited to cash incentives, rent abatement or leasehold improvements paid by the lessor.

Finance Leases

We capitalize assets acquired under finance leases at lease commencement and amortize them to depreciation expense over the lesser of the useful life of the asset or the lease term on either a straight-line or a units-of-consumption basis, depending on the asset leased. We record the present value of the related lease payments as a debt obligation. Our finance lease liability relates primarily to certain long-term landfill operating agreements that require minimum lease payments with offsetting finance lease assets recorded as part of the landfill development costs.

A summary of the lease classification on our consolidated balance sheet as of September 30, 2019 follows:

		2019
Assets
Operating right-of-use lease assets	Other assets	$	243.1

9. INCOME TAXES

Our effective tax rate, exclusive of non-controlling interests, for the three and nine months ended September 30, 2019 was 19.3% and 22.5%, respectively. Our effective tax rate, exclusive of non-controlling interests, for the three and nine months ended September 30, 2018 was 22.7% and 23.6%, respectively. Our effective tax rate, for the three and nine months ended September 30, 2019, was favorably affected by settlements of various state matters and the realization of additional federal and state benefits as well as adjustments to deferred taxes due to the completion of our 2018 tax returns.

Cash paid for income taxes was a net refund of $4.3 million and a net payment of $43.5 million for the nine months ended September 30, 2019 and 2018, respectively. Cash taxes have been favorably impacted from the receipt of funds from amended returns filed during 2018.

We have deferred tax assets related to state net operating loss carryforwards. We provide a partial valuation allowance due to uncertainty surrounding the future utilization of these carryforwards in the taxing jurisdictions where the loss carryforwards exist. When determining the need for a valuation allowance, we consider all positive and negative evidence, including recent financial results, scheduled reversals of deferred tax liabilities, projected future taxable income and tax planning strategies.

As a result of changes in U.S. tax law and our ongoing efforts to evaluate, streamline and maximize the efficiency of our tax footprint, we could adjust our valuation allowance in a future period if there is sufficient evidence to support a conclusion that it is more certain than not that a portion of the state net operating loss carryforwards, on which we currently provide a valuation allowance, would be realized. Future changes in our valuation allowance could have a material effect on our results of operations in the period recorded.

The realization of our deferred tax asset for state loss carryforwards ultimately depends upon the existence of sufficient taxable income in the appropriate state taxing jurisdictions in future periods. The weight given to the positive and negative evidence is commensurate with the extent such evidence can be objectively verified. We continue to regularly monitor both positive and negative evidence in determining the ongoing need for a valuation allowance. As of September 30, 2019, the valuation allowance associated with our state loss carryforwards was approximately $68 million.

We are subject to income tax in the United States and Puerto Rico, as well as in multiple state jurisdictions. Our compliance with income tax rules and regulations is periodically audited by taxing authorities. These authorities may challenge the positions taken in our tax filings. We are currently under examination or administrative review by the Internal Revenue Service, state and local taxing authorities and Puerto Rico for various tax years.

We believe that our recorded liabilities for uncertain tax positions are adequate. However, a significant assessment against us in excess of the liabilities recorded could have a material adverse effect on our consolidated financial position, results of operations and cash flows. As of September 30, 2019, we are unable to estimate the resolution of our gross unrecognized benefits over the next 12 months.

We recognize interest and penalties as incurred within the provision for income taxes in the consolidated statement of income. As of September 30, 2019, we accrued a liability for penalties of $0.3 million and a liability for interest (including interest on penalties) of $11.0 million related to our uncertain tax positions.

As of September 30, 2019, there were less than 0.1 million repurchased shares pending settlement, resulting in an associated $0.1 million of share repurchases unpaid and included within other accrued liabilities. As of September 30, 2018, there were no repurchased shares pending settlement.

In October 2017, our Board of Directors added $2.0 billion to the existing share repurchase authorization that now extends through December 31, 2020. Share repurchases under the program may be made through open market purchases or privately negotiated transactions in accordance with applicable federal securities laws. While the Board of Directors has approved the program, the timing of any purchases, the prices and the number of shares of common stock to be purchased will be determined by our management, at its discretion, and will depend upon market conditions and other factors. The share repurchase program may be extended, suspended or discontinued at any time. As of September 30, 2019, the remaining authorized purchase capacity under our October 2017 repurchase program was $750.3 million.

Dividends

In July 2019, our Board of Directors approved a quarterly dividend of $0.405 per share. Cash dividends declared were $370.2 million for the nine months ended September 30, 2019. As of September 30, 2019, we recorded a quarterly dividend payable of $129.3 million to shareholders of record at the close of business on October 1, 2019.

Earnings per Share

Basic earnings per share is computed by dividing net income attributable to Republic Services, Inc. by the weighted average number of common shares (including vested but unissued RSUs and PSUs) outstanding during the period. Diluted earnings per share is based on the combined weighted average number of common shares and common share equivalents outstanding, which include, where appropriate, the assumed exercise of employee stock options, unvested RSUs and unvested PSUs at the expected attainment levels. We use the treasury stock method in computing diluted earnings per share.

Earnings per share for the three and nine months ended September 30, 2019 and 2018 are calculated as follows (in thousands, except per share amounts):

Fair Value Measurements

In measuring fair values of assets and liabilities, we use valuation techniques that maximize the use of observable inputs (Level 1) and minimize the use of unobservable inputs (Level 3). We also use market data or assumptions that we believe market participants would use in pricing an asset or liability, including assumptions about risk when appropriate.

The carrying value for certain of our financial instruments, including cash, accounts receivable, accounts payable and certain other accrued liabilities, approximates fair value because of their short-term nature.

Total Debt

As of September 30, 2019 and December 31, 2018, the carrying value of our total debt was $8.6 billion and $8.3 billion, respectively and the fair value of our total debt was $9.4 billion and $8.7 billion, respectively. The estimated fair value of our fixed rate senior notes and debentures is based on quoted market prices. The fair value of our remaining notes payable, tax-exempt financings and borrowings under our credit facilities approximates the carrying value because the interest rates are variable. The fair value estimates are based on Level 2 inputs of the fair value hierarchy as of September 30, 2019 and December 31, 2018. See Note 7, Debt, for further information related to our debt.

Derivative Contracts

Contemporaneously with the issuance of our 2.500% Notes in August 2019, we amended interest rate lock agreements with a notional value of $375.0 million, extending the mandatory maturity date from 2019 to 2024 and dedesignated them as cash flow hedges (the Extended Interest Rate Swaps). In addition, we entered into an offsetting interest rate swap to offset future exposures to fair value fluctuations of the Extended Interest Rate Swaps (the Offsetting Interest Rate Swaps). The fair value of these free standing derivatives was determined using standard valuation models with assumptions about interest rates being based on those observed in underlying markets (Level 2 in the fair value hierarchy).

As of September 30, 2019, the fair value of the Extended Interest Rate Swaps was a liability of $24.2 million which was included in other long-term liabilities in our consolidated balance sheet, and the fair value of the Offsetting Interest Rate Swaps was an asset of $4.9 million and was included in other assets in our consolidated balance sheet. For the three and nine months ended September 30, 2019, we recognized a loss of $5.4 million on the change in fair value of the Extended Interest Rate Swaps, with an offsetting gain of $4.9 million on the Offsetting Interest Rate Swaps. The change in fair value was recorded directly in earnings as an adjustment to interest expense in our consolidated statement of income.

Contingent Consideration

In April 2015, we entered into a waste management contract with the County of Sonoma, California to operate the county's waste management facilities. As of September 30, 2019, the Sonoma contingent consideration represents the fair value of $65.9 million payable to the County of Sonoma based on the achievement of future annual tonnage targets through the expected remaining capacity of the landfill, which we estimate to be approximately 30 years. The potential undiscounted amount of all future contingent payments that we could be required to make under the waste management contract is estimated to be between approximately $79 million and $168 million. During the nine months ended September 30, 2019, the activity in the contingent consideration liability included accretion, which was offset by concession payments made in the ordinary course of business. There were no changes to the estimate of fair value. The contingent consideration liability is classified within Level 3 of the fair value hierarchy.

In 2017, we recognized additional contingent consideration associated with the acquisition of a landfill. As of September 30, 2019, the contingent consideration of $4.1 million represents the fair value of amounts payable to the seller based on annual volume of tons disposed at the landfill. During the nine months ended September 30, 2019, the activity in the contingent consideration liability included accretion, which was offset by concession payments made in the ordinary course of business. There were no changes to the estimate of fair value. The contingent consideration liabilities are classified within Level 3 of the fair value hierarchy.

In June 2019, we recognized additional contingent consideration associated with the acquisition of a collection business. As of September 30, 2019, the contingent consideration of $2.5 million represents the fair value of amounts payable to the seller based on annual volume of tons collected from certain customers of the business. The fair value of the contingent consideration was determined using probability assessments of the expected future payments over the estimated customer relationships, and applying a discount rate. The future payments are based on significant inputs that are not observable in the market. Key assumptions include annual collection volumes, which are subject to remeasurement at each reporting date. The contingent consideration liabilities are classified within Level 3 of the fair value hierarchy.

13. SEGMENT REPORTING

Our senior management evaluates, oversees and manages the financial performance of our operations through two field groups, referred to as Group 1 and Group 2. Group 1 primarily consists of geographic areas located in the western United States, and Group 2 primarily consists of geographic areas located in the southeastern and mid-western United States, and the eastern seaboard of the United States. These two groups are presented below as our reportable segments, which provide integrated waste management services consisting of non-hazardous solid waste collection, transfer, recycling, disposal and environmental services.

Intercompany revenue reflects transactions within and between segments that generally are made on a basis intended to reflect the market value of such services. Capital expenditures for corporate entities primarily include vehicle inventory acquired but not yet assigned to operating locations and facilities. Corporate functions include legal, tax, treasury, information technology, risk management, human resources, closed landfills and other administrative functions.

Subsequent Event

In October 2019, certain of our owned and operated facilities in our Group 1 segment were impacted by separate fire-related events. We are estimating the financial impact of any damage to the facilities, and we may experience higher operating expenses or asset impairments in the fourth quarter as a result of these events.

14. REVENUE

Our operations primarily consist of providing collection, transfer and disposal of non-hazardous solid waste, recovering and recycling of certain materials, and environmental services. The following table disaggregates our revenue by service line for the three and nine months ended September 30, 2019 and 2018 (in millions of dollars and as a percentage of revenue):

	Three Months Ended September 30,								Nine Months Ended September 30,

Other non-core revenue consists primarily of revenue from National Accounts, which represents the portion of revenue generated from nationwide or regional contracts in markets outside our operating areas where the associated waste handling services are subcontracted to local operators. Consequently, substantially all of this revenue is offset with related subcontract costs, which are recorded in cost of operations.

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, we recognize revenue at the time we perform a service. In the event that we bill for services in advance of performance, we recognize deferred revenue for the amount billed and subsequently recognize revenue at the time the service is provided. Substantially all of the deferred revenue recognized as of December 31, 2018 was recognized as revenue during the nine months ended September 30, 2019 when the service was performed.

See Note 13, Segment Reporting, for additional information regarding revenue by reportable segment.

Revenue Recognition

Our service obligations of a long-term nature, e.g., solid waste collection service contracts, are satisfied over time, and we recognize revenue based on the value provided to the customer during the period. The amount billed to the customer is based on variable elements such as the number of residential homes or businesses for which collection services are provided, the volume of waste collected, transported and disposed, and the nature of the waste accepted. We do not disclose the value of unsatisfied performance obligations for these contracts as our right to consideration corresponds directly to the value provided to the customer for services completed to date and all future variable consideration is allocated to wholly unsatisfied performance obligations.

Additionally, certain elements of our long-term customer contracts are unknown upon entering into the contract, including the amount that will be billed in accordance with annual price escalation clauses, our fuel recovery fee program and commodity prices. The amount to be billed is often tied to changes in an underlying base index such as a consumer price index or a fuel or commodity index, and revenue can be recognized once the index is established for the period.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

Deferred Contract Costs

We incur certain upfront payments to acquire customer contracts which are recognized as other assets in our consolidated balance sheet, and we amortize the asset over the respective contract life. In addition, we recognize sales commissions that represent an incremental cost of the contract as other assets in our consolidated balance sheets, and we amortize the asset over the average life of the customer relationship. As of September 30, 2019 and December 31, 2018, we recognized $82.4 million and $89.2 million, respectively, of deferred contract costs and capitalized sales commissions. During the three and nine months ended September 30, 2019, we amortized $2.9 million and $8.9 million of capitalized sales commissions to selling, general and administrative expenses and $1.6 million and $4.6 million of other deferred contract costs as a reduction of revenue, respectively. During the three and nine months ended September 30, 2018, we amortized $2.8 million and $8.3 million of capitalized sales commissions to selling, general and administrative expenses and $1.6 million and $4.4 million of other deferred contract costs as a reduction of revenue, respectively.

15. COMMITMENTS AND CONTINGENCIES

Legal Proceedings

We are subject to extensive and evolving laws and regulations and have implemented safeguards to respond to regulatory requirements. In the normal course of our business, we become involved in legal proceedings. Some may result in fines, penalties or judgments against us, or settlements, which may impact earnings and cash flows for a particular period. Although we cannot predict the ultimate outcome of any legal matter with certainty, we do not believe the outcome of any of our pending legal proceedings will have a material adverse impact on our consolidated financial position, results of operations or cash flows.

As used herein, the term legal proceedings refers to litigation and similar claims against us and our subsidiaries, excluding: (1) ordinary course accidents, general commercial liability and workers' compensation claims, which are covered by insurance programs, subject to customary deductibles, and which, together with insured employee health care costs, are discussed in Note 5, Other Liabilities; and (2) environmental remediation liabilities, which are discussed in Note 6, Landfill and Environmental Costs.

We accrue for legal proceedings when losses become probable and reasonably estimable. We have recorded an aggregate accrual of approximately $19 million relating to our outstanding legal proceedings as of September 30, 2019. As of the end of each applicable reporting period, we review each of our legal proceedings and, where it is probable that a liability has been incurred, we accrue for all probable and reasonably estimable losses. Where we can reasonably estimate a range of losses we may incur regarding such a matter, we record an accrual for the amount within the range that constitutes our best estimate. If we can reasonably estimate a range but no amount within the range appears to be a better estimate than any other, we use the amount that is the low end of such range. If we had used the high ends of such ranges, our aggregate potential liability would be approximately $15 million higher than the amount recorded as of September 30, 2019.

Multiemployer Pension Plans

We contribute to 26 multiemployer pension plans under collective bargaining agreements covering union-represented employees. These plans generally provide retirement benefits to participants based on their service to contributing employers. We do not administer these plans.

Under current law regarding multiemployer pension plans, a plan’s termination, our voluntary withdrawal (which we consider from time to time) or the mass withdrawal of all contributing employers from any under-funded multiemployer pension plan (each, a Withdrawal Event) would require us to make payments to the plan for our proportionate share of the plan’s unfunded vested liabilities. During the course of operating our business, we incur Withdrawal Events regarding certain of our multiemployer pension plans. We accrue for such events when losses become probable and reasonably estimable.

Restricted Cash and Marketable Securities

Our restricted cash and marketable securities include, among other things, restricted cash and marketable securities held for capital expenditures under certain debt facilities, restricted cash pursuant to a holdback arrangement, restricted cash and marketable securities pledged to regulatory agencies and governmental entities as financial guarantees of our performance under certain collection, landfill and transfer station contracts and permits, and relating to our final capping, closure and post-closure obligations at our landfills, and restricted cash and marketable securities related to our insurance obligations.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion in conjunction with the unaudited consolidated financial statements and notes thereto included under Item 1 of Part I of this Form 10-Q. In addition, you should refer to our audited consolidated financial statements and notes thereto and related Management’s Discussion and Analysis of Financial Condition and Results of Operations appearing in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

Disclosure Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains certain forward-looking information about us that is intended to be covered by the safe harbor for “forward-looking statements” provided by the Private Securities Litigation Reform Act of 1995. Forward-looking statements are statements that are not historical facts. Words such as “guidance,” “expect,” “will,” “may,” “anticipate,” “plan,” “estimate,” “project,” “intend,” “should,” “can,” “likely,” “could,” “outlook” and similar expressions are intended to identify forward-looking statements. In particular, information appearing under this “Management's Discussion and Analysis of Financial Condition and Results of Operations” includes forward-looking statements. These statements include information about our plans, strategies and prospects. Forward-looking statements are not guarantees of performance. These statements are based upon the current beliefs and expectations of our management and are subject to risk and uncertainties that could cause actual results to differ materially from those expressed in, or implied or projected by, the forward-looking information and statements. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot assure you that the expectations will prove to be correct. Among the factors that could cause actual results to differ materially from the expectations expressed in the forward-looking statements are acts of war, riots or terrorism, and the impact of these acts on economic, financial and social conditions in the United States as well as our dependence on large, long-term collection, transfer and disposal contracts. More information on factors that could cause actual results or events to differ materially from those anticipated is included from time to time in our reports filed with the Securities and Exchange Commission, including our Annual Report on Form 10-K for the year ended December 31, 2018, particularly under Part I, Item 1A - Risk Factors. Additionally, new risk factors emerge from time to time and it is not possible for us to predict all such risk factors, or to assess the impact such risk factors might have on our business. We undertake no obligation to update publicly any forward-looking statements whether as a result of new information, future events or otherwise, except as required by law.

Overview

Republic is the second largest provider of non-hazardous solid waste collection, transfer, disposal, recycling, and environmental services in the United States, as measured by revenue. As of September 30, 2019, we operated facilities in 41 states and Puerto Rico through 342 collection operations, 211 transfer stations, 190 active landfills, 88 recycling processing centers, 8 treatment, recovery and disposal facilities, 15 salt water disposal wells and 2 deep injection wells. We are engaged in 75 landfill gas to energy and renewable energy projects and had post-closure responsibility for 129 closed landfills.

Revenue for the nine months ended September 30, 2019 increased by 2.8% to $7,722.7 million compared to $7,510.9 million for the same period in 2018. This change in revenue is due to increases in average yield of 2.8%, fuel recovery fees of 0.1%, and acquisitions, net of divestitures of 0.7%, partially offset by the impact of decreased volumes of (0.4)%, environmental services of (0.3)%, and recycling processing and commodity sales of (0.1)%.

The following table summarizes our revenue, expenses and operating income for the three and nine months ended September 30, 2019 and 2018 (in millions of dollars and as a percentage of revenue):

We believe that presenting adjusted pre-tax income, adjusted net income – Republic, and adjusted diluted earnings per share, which are not measures determined in accordance with U.S. GAAP, provides an understanding of operational activities before the financial impact of certain items. We use these measures, and believe investors will find them helpful, in understanding the ongoing performance of our operations separate from items that have a disproportionate impact on our results for a particular period. We have incurred comparable charges and costs in prior periods, and similar types of adjustments can reasonably be expected to be recorded in future periods. Our definitions of adjusted pre-tax income, adjusted net income – Republic, and adjusted diluted earnings per share may not be comparable to similarly titled measures presented by other companies. Further information on each of these adjustments is included below.

Loss on extinguishment of debt and other related costs. During the nine months ended September 30, 2018, we incurred a $0.3 million loss on the extinguishment of certain financing arrangements.

Restructuring charges. In January 2018, we eliminated certain positions following the consolidation of select back-office functions, including but not limited to the integration of our National Accounts support functions into our existing corporate support functions. These changes include a reduction in administrative staffing and the closure of certain office locations.

35

During the three and nine months ended September 30, 2019, we incurred restructuring charges of $8.5 million and $13.0 million, respectively, that primarily related to upgrades to our back-office software systems. During the three and nine months ended September 30, 2018, we incurred restructuring charges of $9.2 million and $22.5 million, respectively, that primarily consisted of severance and other employee termination benefits and the closure of offices with lease agreements with non-cancelable terms. We paid $7.9 million and $18.7 million during the nine months ended September 30, 2019 and 2018, respectively, related to these restructuring efforts.

In 2019, we expect to incur additional restructuring charges of approximately $3 million to $5 million primarily related to upgrades to our back-office software systems. Substantially all of these restructuring charges will be recorded in our corporate segment.

Incremental contract startup costs - large municipal contract. Although our business regularly incurs startup costs under municipal contracts, we specifically identify in the tables above the startup costs with respect to an individual municipal contract (and do not adjust for other startup costs under other contracts in 2019 or 2018). We do this because of the magnitude of the costs involved with this particular municipal contract and the unusual nature for the time period in which they were incurred.

During the nine months ended September 30, 2019, we incurred costs of $0.7 million, and during the three and nine months ended September 30, 2018, we incurred costs of $0.1 million and $5.4 million, respectively, related to the implementation of a large municipal contract. These costs did not meet the capitalization criteria prescribed by the new revenue recognition standard.

Adoption of the Tax Act. The Tax Act was enacted on December 22, 2017. Among other things, the Tax Act reduced the U.S. federal corporate tax rate from 35% to 21%. For the year ended December 31, 2017, we recorded provisional amounts based on our estimates of the Tax Act's effect to our deferred taxes, uncertain tax positions, and one-time transition tax. During the three months ended September 30, 2018, we adjusted the provisional amounts recorded as of December 31, 2017 for the one-time transition tax, deferred taxes and uncertain tax positions. These adjustments increased our tax provision by $0.3 million.

Gain on disposition of assets and asset impairments, net. During the three and nine months ended September 30, 2019, we recorded a net gain on disposition of assets and asset impairments related to business divestitures of $24.0 million and $23.5 million, respectively. During the three and nine months ended September 30, 2018, we recorded a net gain on disposition of assets and asset impairments related to business divestitures of $4.6 million and $5.3 million, respectively.

Acquisition integration and deal costs. Although our business regularly incurs costs related to acquisitions, we specifically identify in the tables above the integration and deal costs incurred during the three and nine months ended September 30, 2019. We do this because of the magnitude of the costs associated with the particular acquisition activity during these time periods. During the three and nine months ended September 30, 2019, we incurred acquisition related integration and deal costs of $1.9 million and $4.4 million, respectively.

Recent Developments

In October 2019, certain of our owned and operated facilities in our Group 1 segment were impacted by separate fire-related events. We are estimating the financial impact of any damage to the facilities, and we may experience higher operating expenses or asset impairments in the fourth quarter as a result of these events.

2020 Preliminary Financial Outlook

Adjusted Diluted Earnings per Share

We are providing our preliminary financial outlook for 2020. This does not represent full detailed guidance, but rather a point-in-time estimate based on current projections of 2019 performance, early indicators from the 2020 budget process and current economic conditions. Consistent with prior practice, we will provide formal guidance in February 2020 once the budget process is complete and full year 2019 results are reported. The following is a summary of anticipated adjusted diluted earnings per share preliminary outlook for the year ending December 31, 2020, which is not a measure determined in accordance with U.S GAAP:

	(Preliminary Outlook) Year Ending December 31, 2020
Diluted earnings per share	$ 3.44 - 3.49
Restructuring charges	0.02
Adjusted diluted earnings per share	$ 3.46 - 3.51

36

We believe that presenting adjusted diluted earnings per share preliminary outlook provides an understanding of operational activities before the financial impact of certain items. We use this measure, and believe investors will find it helpful, in understanding the ongoing performance of our operations separate from items that have a disproportionate impact on our results for a particular period. We have incurred comparable charges and costs in prior periods, and similar types of adjustments can reasonably be expected to be recorded in future periods. Our definition of adjusted diluted earnings per share may not be comparable to similarly titled measures presented by other companies.

Results of Operations

Revenue

We generate revenue primarily from our solid waste collection operations. Our remaining revenue is from other services, including transfer station, landfill disposal, recycling, and environmental services. Our residential, small-container and large-container collection operations in some markets are based on long-term contracts with municipalities. Certain of our municipal contracts have annual price escalation clauses that are tied to changes in an underlying base index such as a consumer price index. We generally provide small-container and large-container collection services to customers under contracts with terms up to three years. Our transfer stations and landfills generate revenue from disposal or tipping fees charged to third parties. Our recycling processing facilities generate revenue from tipping fees charged to third parties and the sale of recycled commodities. Our revenue from environmental services consists mainly of fees we charge for the treatment and disposal of liquid and solid waste derived from the production of oil and natural gas. Other revenue consists primarily of revenue from National Accounts, which represents the portion of revenue generated from nationwide or regional contracts in markets outside our operating areas where the associated waste handling services are subcontracted to local operators. Consequently, substantially all of this revenue is offset with related subcontract costs, which are recorded in cost of operations.

The following table reflects our revenue by service line for the three and nine months ended September 30, 2019 and 2018 (in millions of dollars and as a percentage of revenue):

	Three Months Ended September 30,								Nine Months Ended September 30,

The following table reflects changes in components of our revenue, as a percentage of total revenue, for the three and nine months ended September 30, 2019 and 2018:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2019		2018		2019		2018

Total	3.2	%	0.1	%	2.8	%	0.4	%
Core price	4.7	%	3.9	%	4.7	%	3.8	%

(1) The increase in volume of 0.1% during the three months ended September 30, 2019 includes an increase of 0.5% due to one additional work day as compared to the three months ended September 30, 2018.

Average yield is defined as revenue growth from the change in average price per unit of service, expressed as a percentage. Core price is defined as price increases to our customers and fees, excluding fuel recovery fees, net of price decreases to retain customers. We also measure changes in average yield and core price as a percentage of related-business revenue, defined as total revenue excluding recycled commodities and fuel recovery fees, to determine the effectiveness of our pricing strategies. Average yield as a percentage of related-business revenue was 2.9% and 3.0% for the three and nine months ended September 30, 2019, respectively, and 2.5% and 2.4% for the same respective periods in 2018. Core price as a percentage of related-business revenue was 5.0% for both the three and nine months ended September 30, 2019, and 4.2% and 4.0% for the same respective periods in 2018.

During the three and nine months ended September 30, 2019, we experienced the following changes in our revenue as compared to the same periods in 2018:

•Average yield increased revenue by 2.8% during both the three and nine months ended September 30, 2019, respectively, due to price increases in all lines of business.

•The fuel recovery fee program, which mitigates our exposure to increases in fuel prices, decreased revenue by (0.2)% during the three months ended September 30, 2019, primarily due to a decrease in fuel prices compared to the same period in 2018. The fuel recovery fee program increased revenue by 0.1% during the nine months ended September 30, 2019 primarily due to an increase in the total revenue subject to the fuel recovery fees. This increase was partially offset by a decrease in fuel prices during the nine months ended September 30, 2019, compared to the same period in 2018.

•Volume increased revenue by 0.1% during the three months ended September 30, 2019 primarily due to one additional workday, partially offset by lower residential and small-container collection volumes as compared to the three months ended September 30, 2018. Volume decreased revenue by (0.4)% during the nine months ended September 30, 2019, primarily due to volume declines in our residential and small-container collection lines of business. The volume declines in our collection lines of business were primarily due to certain non-regrettable losses during the nine months ended September 30, 2019 as compared to the same period in 2018. In addition, special waste landfill volumes decreased during the three and nine months ended September 30, 2019 as compared to the same periods in 2018.

•Recycling processing and commodity sales decreased revenue by (0.3)% and (0.1)% during the three and nine months ended September 30, 2019, respectively, primarily due to a decline in overall commodity prices as compared to the same periods in 2018. The average price for recycled commodities, excluding glass and organics, for the three and nine months ended September 30, 2019 was $72 and $81 per ton, respectively, compared to $106 and $103 per ton for the same periods in 2018.

38

Changing market demand for recycled commodities causes volatility in commodity prices. At current volumes and mix of materials, we believe a $10 per ton change in the price of recycled commodities will change both annual revenue and operating income by approximately $18 million.

•Acquisitions, net of divestitures, increased revenue by 1.2% and 0.7% during the three and nine months ended September 30, 2019, respectively, due to our continued growth strategy of acquiring privately held solid waste, recycling and environmental services companies that complement our existing business platform.

•Environmental services decreased revenue by (0.4)% and (0.3)% during the three and nine months ended September 30, 2019, respectively, primarily due to a decline in drilling activity and increased competition in the Permian Basin.

Cost of Operations

Cost of operations includes labor and related benefits, which consists of salaries and wages, health and welfare benefits, incentive compensation and payroll taxes. It also includes transfer and disposal costs representing tipping fees paid to third party disposal facilities and transfer stations; maintenance and repairs relating to our vehicles, equipment and containers, including related labor and benefit costs; transportation and subcontract costs, which include costs for independent haulers that transport our waste to disposal facilities and costs for local operators who provide waste handling services associated with our National Accounts in markets outside our standard operating areas; fuel, which includes the direct cost of fuel used by our vehicles, net of fuel tax credits; disposal fees and taxes, consisting of landfill taxes, host community fees and royalties; landfill operating costs, which include financial assurance, leachate disposal, remediation charges and other landfill maintenance costs; risk management costs, which include casualty insurance premiums and claims; cost of goods sold, which includes material costs paid to suppliers; and other, which includes expenses such as facility operating costs, equipment rent and gains or losses on sale of assets used in our operations.

The following table summarizes the major components of our cost of operations for the three and nine months ended September 30, 2019 and 2018 (in millions of dollars and as a percentage of revenue):

	Three Months Ended September 30,								Nine Months Ended September 30,
	2019				2018				2019				2018
Labor and related benefits	$	558.9	21.1	%	$	536.1	20.9	%	$	1,647.7	21.3	%	$	1,604.2	21.4	%
Transfer and disposal costs	216.5		8.2		214.9		8.4		634.8		8.2		617.8		8.2
Maintenance and repairs	265.0		10.0		250.8		9.8		757.8		9.8		742.3		9.9
Transportation and subcontract costs	179.1		6.8		166.5		6.5		504.7		6.6		482.3		6.4

Other	115.1		4.3		109.2		4.3		328.5		4.3		317.8		4.2
Total cost of operations	$	1,631.4	61.6	%	$	1,577.4	61.5	%	$	4,754.4	61.6	%	$	4,624.4	61.6	%

These cost categories may change from time to time and may not be comparable to similarly titled categories presented by other companies. As such, you should take care when comparing our cost of operations by component to that of other companies.

Our cost of operations increased in aggregate dollars for the three months ended September 30, 2019 partly due to one additional workday as compared to the same period in 2018. Our cost of operations further increased in aggregate dollars for the three and nine months ended September 30, 2019 compared to the same periods in 2018 as a result of the following:

•Labor and related benefits increased in aggregate dollars due to higher hourly and salaried wages as a result of annual merit increases along with increased headcount attributable to acquisition-related growth.

•Transfer and disposal costs increased in aggregate dollars primarily due to an increase in third party disposal rates. During the three and nine months ended September 30, 2019 and 2018, approximately 68% of the total waste volume we collected was disposed at landfill sites that we own or operate (internalization).

•Maintenance and repairs expense increased in aggregate dollars due to the complexity of trucks, including the cost of parts and internal labor.

•Transportation and subcontract costs increased in aggregate dollars due to increased third party transportation rates and acquisition related activity.

39

•Fuel costs decreased during the three and nine months ended September 30, 2019 due to a decline in both fuel prices and collection volumes. The decrease in fuel costs during the nine months ended September 30, 2019 was partially offset by favorable compressed natural gas (CNG) tax credits of approximately $15 million that were enacted in 2018, retroactively effective to 2017 and recognized during the same period in 2018, which did not recur in 2019. The national average diesel fuel cost per gallon for the three and nine months ended September 30, 2019 was $3.02 and $3.05, respectively, as compared to $3.24 and $3.15 for the same periods in 2018.

At current consumption levels, we believe a twenty-cent per gallon change in the price of diesel fuel would change our fuel costs by approximately $26 million per year. Offsetting these changes in fuel expense would be changes in our fuel recovery fee charged to our customers. At current participation rates, a twenty-cent per gallon change in the price of diesel fuel changes our fuel recovery fee by approximately $25 million per year.

•Landfill operating costs increased due to increased leachate treatment, transportation, and disposal costs, partially offset by certain favorable remediation adjustments.

Depreciation, Amortization and Depletion of Property and Equipment

The following table summarizes depreciation, amortization and depletion of property and equipment for the three and nine months ended September 30, 2019 and 2018 (in millions of dollars and as a percentage of revenue):

	Three Months Ended September 30,								Nine Months Ended September 30,
	2019				2018				2019				2018
Depreciation and amortization of property and equipment	$	164.0	6.2	%	$	160.9	6.3	%	$	484.4	6.3	%	$	482.9	6.4	%
Landfill depletion and amortization	89.5		3.4		84.5		3.3		259.0		3.3		247.3		3.3
Depreciation, amortization and depletion expense	$	253.5	9.6	%	$	245.4	9.6	%	$	743.4	9.6	%	$	730.2	9.7	%

Depreciation and amortization of property and equipment for the three and nine months ended September 30, 2019 increased in aggregate dollars due to additional assets acquired with our acquisitions, partially offset by the full depreciation of certain assets recognized in our 2008 acquisition of Allied Waste Industries, Inc.

During the three and nine months ended September 30, 2019, landfill depletion and amortization expense increased in aggregate dollars, primarily due to favorable one-time amortization adjustments recorded during the three and nine months ended September 30, 2018, which did not recur in 2019 and an increase in our overall average depletion rate.

Amortization of Other Intangible Assets

Expenses for amortization of other intangible assets were $4.8 million and $14.4 million, or 0.2% of revenue, for the three and nine months ended September 30, 2019, respectively, compared to $14.9 million and $45.0 million, or 0.6% of revenue, for each of the same periods in 2018. Our other intangible assets primarily relate to customer relationships and, to a lesser extent, non-compete agreements. Amortization expense decreased primarily due to the full amortization of certain intangible assets recognized in our 2008 acquisition of Allied Waste Industries, Inc.

Amortization of Other Assets

Expenses for amortization of other assets were $9.0 million and $25.3 million, or 0.3% of revenue, for the three and nine months ended September 30, 2019, respectively, compared to $2.1 million and $5.8 million, or 0.1% of revenue, for the same periods in 2018. Our other assets primarily relate to the prepayment of fees and capitalized implementation costs associated with cloud-based hosting arrangements. Effective January 1, 2019, we adopted ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) No. 2018-15 Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (ASU 2018-15) on a prospective basis. During the three and nine months ended September 30, 2018, we recognized $5.3 million and $14.7 million, respectively, of amortization related to the prepayment of fees as selling, general and administrative expenses. During the three and nine months ended September 30, 2019, we recognized $6.1 million and $17.9 million, respectively, of amortization related to the prepayment of similar fees in amortization of other assets.

Accretion Expense

Accretion expense was $20.5 million and $61.4 million, or 0.8% of revenue, for the three and nine months ended September 30, 2019, respectively, compared to $20.1 million and $60.7 million, or 0.8% of revenue, for each of the same periods in 2018. Accretion expense has remained relatively unchanged as our asset retirement obligations have remained relatively consistent period over period.

40

Selling, General and Administrative Expenses

Selling, general and administrative expenses include salaries, health and welfare benefits, and incentive compensation for corporate and field general management, field support functions, sales force, accounting and finance, legal, management information systems, and clerical and administrative departments. Other expenses include rent and office costs, fees for professional services provided by third parties, legal settlements, marketing, investor and community relations services, directors’ and officers’ insurance, general employee relocation, travel, entertainment and bank charges. Restructuring charges are excluded from selling, general and administrative expenses and are discussed separately.

The following table summarizes our selling, general and administrative expenses for the three and nine months ended September 30, 2019 and 2018 (in millions of dollars and as a percentage of revenue):

	Three Months Ended September 30,								Nine Months Ended September 30,
	2019				2018				2019				2018
Salaries and related benefits	$	186.0	7.0	%	$	173.9	6.8	%	$	552.7	7.2	%	$	520.8	6.9	%
Provision for doubtful accounts	7.5		0.3		10.8		0.4		23.4		0.3		24.4		0.3
Other	81.9		3.1		76.2		3.0		230.2		2.9		229.8		3.1
Total selling, general and administrative expenses	$	275.4	10.4	%	$	260.9	10.2	%	$	806.3	10.4	%	$	775.0	10.3	%

These cost categories may change from time to time and may not be comparable to similarly titled categories presented by other companies. As such, you should take care when comparing our selling, general and administrative expenses by cost component to those of other companies.

The most significant items affecting our selling, general and administrative expenses during the three and nine months ended September 30, 2019 and 2018 are summarized below:

•Salaries and related benefits increased primarily due to higher incentive pay and wages, benefits, and other payroll related items resulting from annual merit increases.

•Other selling, general and administrative expenses increased in aggregate dollars for the three and nine months ended September 30, 2019, primarily due to favorable legal settlements received during the three and nine months ended September 30, 2018, which did not recur in the same periods in 2019, as well as higher consulting and professional fees. The increase was partially offset by our adoption of ASU 2018-15. During the three and nine months ended September 30, 2018, we recognized $5.3 million and $14.7 million, respectively, of amortization related to the prepayment of certain fees as selling, general, and administrative expenses. The amortization for prepayments of similar fees was recognized as amortization of other assets during the three and nine months ended September 30, 2019.

Gain on Disposition of Assets and Asset Impairments, Net

We strive to have a number one or number two market position in each of the markets we serve, or have a clear path on how we will achieve a leading market position over time. Where we cannot establish a leading market position, or where operations are not generating acceptable returns, we may decide to divest certain assets and reallocate resources to other markets. Asset or

business divestitures could result in gains, losses or asset impairment charges that may be material to our results of operations

in a given period.

During the three and nine months ended September 30, 2019, we recorded a net gain on disposition of assets and asset impairments related to business divestitures of $24.0 million and $23.5 million, respectively. During the three and nine months ended September 30, 2018, we recorded a net gain on disposition of assets and asset impairments related to business divestitures of $4.6 million and $5.3 million, respectively.

Restructuring Charges

In January 2018, we eliminated certain positions following the consolidation of select back-office functions, including but not limited to the integration of our National Accounts support functions into our existing corporate support functions. These changes include a reduction in administrative staffing and closing of certain office locations.

During the three and nine months ended September 30, 2019, we incurred restructuring charges of $8.5 million and $13.0 million, respectively, that primarily related to upgrades to our back-office software systems. During the three and nine months ended September 30, 2018, we incurred restructuring charges of $9.2 million and $22.5 million, respectively, that primarily consisted of severance and other employee termination benefits and the closure of offices with lease agreements with non-cancelable terms. We paid $7.9 million and $18.7 million during the nine months ended September 30, 2019 and 2018, respectively, related to these restructuring efforts.

Interest Expense

The following table provides the components of interest expense, including accretion of debt discounts and accretion of discounts primarily associated with environmental and risk insurance liabilities assumed in acquisitions, for the three and nine months ended September 30, 2019 and 2018 (in millions of dollars):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2019		2018		2019		2018
Interest expense on debt	$	89.0	$	88.1	$	266.8	$	260.3
Non-cash interest	11.8		10.0		34.9		31.4
Less: capitalized interest	(2.8)		(2.1)		(4.8)		(4.4)
Total interest expense	$	98.0	$	96.0	$	296.9	$	287.3

Total interest expense for the three and nine months ended September 30, 2019 increased primarily due to the increase in debt outstanding during the period. Cash paid for interest, excluding net swap settlements for our interest rate swaps and locks, was $257.1 million for the nine months ended September 30, 2019 and $255.6 million for the nine months ended September 30, 2018.

Effective January 1, 2019, we adopted ASU 2016-02, Leases (Topic 842) (ASC 842 or the new leasing standard) using the optional transition method prescribed by ASU 2018-11, Leases (Topic 842): Targeted Improvements. Under the new leasing standard, we will present variable lease costs associated with our finance leases as a component of non-cash interest expense. Variable lease costs are recognized in our consolidated statement of income in the period incurred. As such, we expect non-cash interest expense to fluctuate each period as the variable elements of these arrangements become known and the cost is incurred.

Income Taxes

Our effective tax rate, exclusive of non-controlling interests, for the three and nine months ended September 30, 2019 was 19.3% and 22.5%, respectively. Our effective tax rate, exclusive of non-controlling interests, for the three and nine months ended September 30, 2018 was 22.7% and 23.6%, respectively. Our effective tax rate for the three and nine months ended September 30, 2019 was favorably affected by settlements of various state matters and the realization of additional federal and state benefits as well as adjustments to deferred taxes due to the completion of our 2018 tax returns.

Cash paid for income taxes was a net refund of $4.3 million and a net payment of $43.5 million for the nine months ended September 30, 2019 and 2018, respectively. Cash taxes have been favorably impacted from the receipt of funds from amended returns filed during 2018.

For additional discussion and detail regarding our income taxes, see Note 9, Income Taxes, to our unaudited consolidated financial statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q.

Reportable Segments

Our senior management evaluates, oversees and manages the financial performance of our operations through two field groups, referred to as Group 1 and Group 2. Group 1 primarily consists of geographic areas located in the western United States, and Group 2 primarily consists of geographic areas located in the southeastern and mid-western United States, and the eastern seaboard of the United States.

42

The two field groups, Group 1 and Group 2, are presented below as our reportable segments, which provide integrated waste management services consisting of non-hazardous solid waste collection, transfer, recycling, disposal and environmental services. Summarized financial information concerning our reportable segments for the three and nine months ended September 30, 2019 and 2018 is shown in the following tables (in millions of dollars and as a percentage of revenue in the case of operating margin):

	Net Revenue		Depreciation, Amortization, Depletion and Accretion Before Adjustments for Asset Retirement Obligations		Adjustments to Amortization Expense for Asset Retirement Obligations		Depreciation, Amortization, Depletion and Accretion		Gain on Disposition of Assets and Impairments, Net		Operating Income (Loss)		Operating Margin

Corporate entities include legal, tax, treasury, information technology, risk management, human resources, closed landfills and other administrative functions. National Accounts revenue included in corporate entities represents the portion of revenue generated from nationwide and regional contracts in markets outside our operating areas where the associated waste handling services are subcontracted to local operators. Consequently, substantially all of this revenue is offset with related subcontract costs, which are recorded in cost of operations.

Significant changes in the revenue and operating margins of our reportable segments comparing the three and nine months ended September 30, 2019 with the same period in 2018 are discussed below:

Group 1

Revenue for the three and nine months ended September 30, 2019 increased 4.5% and 3.9%, respectively, due to an increase in average yield in all lines of business and an increase in volume in our collection and transfer stations lines of business, which was partially offset by volume declines in our landfill line of business.

43

Operating income in Group 1 increased from $298.5 million for the three months ended September 30, 2018, or 24.3% operating income margin, to $316.0 million for the three months ended September 30, 2019, or a 24.6% operating income margin. Operating income in Group 1 increased from $851.6 million for the nine months ended September 30, 2018, or 23.6% operating income margin, to $913.1 million for the nine months ended September 30, 2019, or a 24.4% operating income margin. The following cost categories impacted operating income margin:

•Cost of operations unfavorably impacted operating income margin for the three months ended September 30, 2019, primarily due to an increase in maintenance and repairs expenses and transportation and subcontract costs, partially offset by a decrease in fuel costs. Cost of operations favorably impacted operating income margin for the nine months ended September 30, 2019, primarily due to a decrease in labor and related benefits and fuel costs as a percentage of revenue, partially offset by an increase in transportation and subcontract costs.

•Selling, general, and administrative expenses favorably impacted operating income margin for the three and nine months ended September 30, 2019, primarily due to a decrease in bad debt expense during the three and nine months ended September 30, 2019.

Group 2

Revenue for the three and nine months ended September 30, 2019 increased 2.0% and 1.9%, respectively, due primarily to increases in average yield in all lines of business, partially offset by volume declines in our collection and transfer stations lines of business.

Operating income in Group 2 increased from $231.4 million for the three months ended September 30, 2018, or a 17.8% operating income margin, to $242.8 million for the three months ended September 30, 2019, or an 18.4% operating income margin. Operating income in Group 2 increased from $666.3 million for the nine months ended September 30, 2018, or a 17.6% operating income margin, to $695.5 million for the nine months ended September 30, 2019, or an 18.0% operating income margin. The following cost categories impacted operating income margin:

•Cost of operations favorably impacted operating income margin for the three and nine months ended September 30, 2019, primarily due to a decrease in transfer and disposal costs, fuel costs, and risk management expenses as a percentage of revenue, partially offset by an increase in landfill operating costs as a percentage of revenue.

•Landfill depletion and amortization unfavorably impacted operating income margin as a result of favorable one-time amortization adjustments recorded during the three and nine months ended September 30, 2018, which did not recur in the same periods in 2019 as well as an increase in our overall average depletion rate. Depreciation favorably impacted operating income margin during the three and nine months ended September 30, 2019, primarily due to the full depreciation of certain assets recognized in our 2008 acquisition of Allied Waste Industries, Inc.

Corporate Entities

Operating loss in our Corporate Entities increased from $89.6 million for the three months ended September 30, 2018 to $91.0 million for the three months ended September 30, 2019. Operating loss in our Corporate Entities increased from $265.3 million for the nine months ended September 30, 2018 to $280.6 million for the nine months ended September 30, 2019. The operating loss for the three and nine months ended September 30, 2019 increased due to favorable CNG tax credits of approximately $15 million that were enacted in 2018, retroactively effective in 2017 and recognized during the three and nine months ended September 30, 2018, favorable legal settlements received during the three and nine months ended September 30, 2018, and higher consulting and professional fees, partially offset by the net gain on disposition of assets and asset impairments related to business divestitures.

Landfill and Environmental Matters

Available Airspace

The following table reflects landfill airspace activity for active landfills we owned or operated during the nine months ended September 30, 2019:

	Balance as of December 31, 2018	New Expansions Undertaken	Landfills Acquired, Net of Divestitures	Permits Granted, Net of Closures	Airspace Consumed	Changes in Engineering Estimates	Balance as of September 30, 2019
Cubic yards (in millions):
Permitted airspace	4,736.8	—	—	35.1	(61.3)	(2.2)	4,708.4
Probable expansion airspace	341.2	6.7	—	(18.1)	—	—	329.8
Total cubic yards (in millions)	5,078.0	6.7	—	17.0	(61.3)	(2.2)	5,038.2
Number of sites:
Permitted airspace	190	—	—	—			190
Probable expansion airspace	12	2	—	(2)			12

As of September 30, 2019, we owned or operated 190 active solid waste landfills with total available disposal capacity estimated to be 5,038.2 million in-place cubic yards. Total available disposal capacity represents the sum of estimated permitted airspace plus an estimate of probable expansion airspace. Engineers develop these estimates at least annually using information provided by annual aerial surveys. As of September 30, 2019, total available disposal capacity is estimated to be 4,708.4 million in-place cubic yards of permitted airspace plus 329.8 million in-place cubic yards of probable expansion airspace. Before airspace included in an expansion area is determined to be probable expansion airspace and, therefore, included in our calculation of total available disposal capacity, it must meet all of our expansion criteria. The average estimated remaining life of all of our landfills is 62 years.

As of September 30, 2019, 12 of our landfills met all of our criteria for including their probable expansion airspace in their total available disposal capacity. At projected annual volumes, these landfills have an estimated remaining average site life of 57 years, including probable expansion airspace. We have other expansion opportunities that are not included in our total available airspace because they do not meet all of our criteria to be deemed probable expansion airspace.

Final Capping, Closure and Post-Closure Costs

As of September 30, 2019, accrued final capping, closure and post-closure costs were $1,339.6 million, of which $80.9 million were current, as reflected in our unaudited consolidated balance sheet in accrued landfill and environmental costs included in Item 1 of Part I of this Quarterly Report on Form 10-Q.

Remediation and Other Charges for Landfill Matters

Bridgeton Landfill. During the nine months ended September 30, 2019, we paid $12.0 million related to management and monitoring of the remediation area for our closed Bridgeton Landfill in Missouri. We continue to work with state and federal regulatory agencies on our remediation efforts. From time to time, this may require us to modify our future operating timeline and procedures, which could result in changes to our expected liability. As of September 30, 2019, the remediation liability recorded for this site was $149.1 million, of which approximately $2 million is expected to be paid during the remainder of 2019. We believe the remaining reasonably possible high-end of our range would be approximately $171 million higher than the amount recorded as of September 30, 2019.

West Lake Landfill Superfund Site. Our subsidiary Bridgeton Landfill, LLC is one of several currently designated Potentially Responsible Parties for the West Lake Landfill Superfund site (West Lake) in Missouri. On September 27, 2018, the U.S. Environmental Protection Agency (EPA) issued a Record of Decision Amendment for West Lake that includes a total undiscounted cost estimate of $229 million over a four- to five-year design and construction timeline. On March 11, 2019, the EPA issued special notice letters under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA) to Bridgeton Landfill, LLC and the other currently designated Potentially Responsible Parties to initiate negotiations to implement the remedy. At this time we are neither able to predict the final design of that remedy, nor estimate how much of the future response costs of the site our subsidiary may agree or be required to pay. During any subsequent administrative proceedings or litigation, our subsidiary will vigorously contest liability for the costs of remediating radiologically-impacted materials generated on behalf of the federal government during the Manhattan Project and delivered to the site by an Atomic Energy Commission licensee and its subcontractor. Currently, we believe we are adequately reserved for our expected remediation liability. However, subsequent events related to remedy design, divisibility, or allocation may require us to modify our expected remediation liability.

45

It is reasonably possible that we will need to adjust our accrued landfill and environmental liabilities to reflect the effects of new or additional information, to the extent that such information impacts the costs, timing or duration of the required actions. Future changes in our estimates of the costs, timing or duration of the required actions could have a material adverse effect on our consolidated financial position, results of operations and cash flows.

Cash Flows Provided by Operating Activities

The most significant items affecting the comparison of our operating cash flows for the nine months ended September 30, 2019 and 2018 are summarized below:

Changes in assets and liabilities, net of effects from business acquisitions and divestitures, decreased our cash flow from operations by $9.1 million during the nine months ended September 30, 2019, compared to a decrease of $92.0 million during the same period in 2018, primarily as a result of the following:

•Our accounts receivable, exclusive of the change in allowance for doubtful accounts and customer credits, increased $65.3 million during the nine months ended September 30, 2019 due to the timing of billings net of collections, compared to a $72.1 million increase in the same period in 2018. As of September 30, 2019, our days sales outstanding were 39.9, or 28.2 days net of deferred revenue, compared to 41.0, or 29.1 days net of deferred revenue, as of September 30, 2018.

47

•Our prepaid expenses and other assets decreased $98.3 million during the nine months ended September 30, 2019, compared to a $13.5 million increase in the same period in 2018, primarily due to timing of our estimated tax payments. Cash paid for income taxes was a net refund of $4.3 million and a net payment of $43.5 million for the nine months ended September 30, 2019 and 2018, respectively.

•Our accounts payable decreased $9.3 million during the nine months ended September 30, 2019, compared to a $58.6 million increase in the same period in 2018, due to the timing of payments.

•Cash paid for capping, closure and post-closure obligations was $47.7 million during the nine months ended September 30, 2019, compared to $42.5 million in the same period in 2018. The increase in cash paid for capping, closure, and post-closure obligations is primarily due to the timing of capping and post-closure payments at certain of our landfill sites.

•Cash paid for remediation obligations was $0.8 million lower during the nine months ended September 30, 2019, compared to the same period in 2018, primarily due to the timing of obligations.

Cash paid for interest, excluding net settlements for our interest rate swaps and locks, was $257.1 million and $255.6 million for the nine months ended September 30, 2019 and 2018, respectively.

We use cash flows from operations to fund capital expenditures, acquisitions, dividend payments, share repurchases and debt repayments.

Cash Flows Used in Investing Activities

The most significant items affecting the comparison of our cash flows used in investing activities for the nine months ended September 30, 2019 and 2018 are summarized below:

•Capital expenditures during the nine months ended September 30, 2019 were $908.3 million, compared with $820.5 million for the same period in 2018.

•During the nine months ended September 30, 2019 and 2018, we paid $455.9 million and $130.5 million, respectively, for acquisitions and investments.

We intend to finance capital expenditures and acquisitions through cash on hand, restricted cash held for capital expenditures, cash flows from operations, our revolving credit facilities, and tax-exempt bonds and other financings. We expect to primarily use cash and borrowings under our revolving credit facilities to pay for future business acquisitions.

Cash Flows Used in Financing Activities

The most significant items affecting the comparison of our cash flows used in financing activities for the nine months ended September 30, 2019 and 2018 are summarized below:

•Net proceeds from notes payable and long-term debt and senior notes were $250.8 million during the nine months ended September 30, 2019, compared to net proceeds of $46.1 million in the same period in 2018.

•During the nine months ended September 30, 2019, we repurchased 4.3 million shares of our stock for $353.8 million compared to repurchases of 8.5 million shares for $574.9 million during the same period in 2018.

•Dividends paid were $361.9 million and $340.0 million during the nine months ended September 30, 2019 and 2018, respectively.

Cash and Cash Equivalents

As of September 30, 2019, we had $55.6 million of cash and cash equivalents and $121.3 million of restricted cash deposits and restricted marketable securities, including $30.4 million of restricted cash and marketable securities pledged to regulatory agencies and governmental entities as financial guarantees of our performance related to our final capping, closure and post-closure obligations at our landfills, and $90.9 million of restricted cash and marketable securities related to our insurance obligations.

Credit Facilities

In 2018, we entered into a $2.25 billion unsecured revolving credit facility (the Credit Facility), which replaced our $1.0 billion and $1.25 billion unsecured credit facilities that would have matured in May 2021 and June 2019, respectively. The Credit Facility matures in June 2023. We may request two one-year extensions of the maturity date but none of the lenders are committed to participate in such extension. The Credit Facility also includes a feature that allows us to increase availability, at our option, by an aggregate amount of up to $1.0 billion through increased commitments from existing lenders or the addition of new lenders. At our option, borrowings under the Credit Facility bear interest at a Base Rate, or a Eurodollar Rate, plus an applicable margin based on our Debt Ratings (all as defined in the Credit Facility agreement).

The Credit Facility requires us to comply with financial and other covenants. To the extent we are not in compliance with these covenants, we cannot pay dividends or repurchase common stock. Compliance with covenants also is a condition for any incremental borrowings under our Credit Facility, and failure to meet these covenants would enable the lenders to require repayment of any outstanding loans (which would adversely affect our liquidity). As of September 30, 2019, our EBITDA to interest ratio was 7.53 compared to the 3.00 minimum required by the covenants, and our total debt to EBITDA ratio was 2.96 compared to the 3.50 maximum allowed by the covenants. As of September 30, 2019, we were in compliance with the covenants under our Credit Facility, and we expect to be in compliance throughout the remainder of 2019.

EBITDA, which is a non-U.S. GAAP measure, is calculated as defined in our Credit Facility agreement. In this context, EBITDA is used solely to provide information regarding the extent to which we are in compliance with debt covenants and is not comparable to EBITDA used by other companies or used by us for other purposes.

Availability under our Credit Facility totaled $1,710.6 million and $1,694.1 million as of September 30, 2019 and December 31, 2018, respectively. The Credit Facility can be used for working capital, capital expenditures, acquisitions, letters of credit and other general corporate purposes. As of September 30, 2019 and December 31, 2018, we had $170.0 million and $159.0 million of borrowings under our Credit Facility, respectively. We had $352.0 million and $379.6 million of letters of credit outstanding under our Credit Facility as of September 30, 2019 and December 31, 2018, respectively.

We also have an Uncommitted Credit Facility, which bears interest at LIBOR, plus an applicable margin and is subject to facility fees defined in the agreement, regardless of usage. We can use borrowings under the Uncommitted Credit Facility for working capital and other general corporate purposes. The agreement governing our Uncommitted Credit Facility requires us to comply with certain covenants. The Uncommitted Credit Facility may be terminated by either party at any time. We had $12.2 million of borrowings and $33.4 million of borrowings under our Uncommitted Credit Facility as of September 30, 2019 and December 31, 2018, respectively.

Senior Notes and Debentures

In August 2019, we issued $900.0 million of 2.500% senior notes due 2024 (the 2.500% Notes). We used the net proceeds from the 2.500% Notes to repay $650.0 million of 5.500% senior notes that matured in September 2019. Any remaining proceeds were used to repay amounts outstanding under our unsecured credit facilities as well as for general corporate purposes. Contemporaneously with this offering, we amended interest rate lock agreements with a notional value of $375.0 million and dedesignated the hedging relationship. There was no ineffectiveness recognized in the termination of these cash flow hedges. In addition, we entered into an offsetting interest rate swap to manage exposure to fluctuations in interest rates associated with the amended agreements. For further detail regarding the effect of our derivative contracts on interest expense, refer to Note 12, Financial Instruments, to our unaudited consolidated financial statements in Item 1 of Part I of this Quarterly Report on Form 10-Q.

In 2018, we issued $800.0 million of 3.950% senior notes due 2028 (the 3.950% Notes). We used the net proceeds from the 3.950% Notes to repay $700.0 million of 3.800% senior notes that matured in May 2018, and any remaining proceeds were used for general corporate purposes. In connection with this offering, we terminated interest rate lock agreements with a notional value of $600.0 million, resulting in net proceeds of $31.1 million. There was no ineffectiveness recognized in the termination of these cash flow hedges.

Our senior notes and debentures are general unsecured obligations. Interest is payable semi-annually.

Tax-Exempt Financings

During the second quarter of 2019, we refinanced $35.0 million of tax-exempt financings and issued $30.0 million of new tax-exempt financings. As of September 30, 2019, we had $1,066.3 million of certain variable rate tax-exempt financings outstanding with maturities ranging from 2020 to 2049. As of December 31, 2018, we had $1,036.8 million of certain variable rate tax-exempt financings outstanding with maturities ranging from 2019 to 2044. Approximately 100% of our tax-exempt financings are remarketed quarterly by remarketing agents to effectively maintain a variable yield. The holders of the bonds can put them back to the remarketing agents at the end of each interest period. To date, the remarketing agents have been able to remarket all of our variable rate unsecured tax-exempt bonds.

49

Finance Leases

We had finance lease liabilities of $112.4 million and $109.5 million as of September 30, 2019 and December 31, 2018, respectively, with maturities ranging from 2019 to 2049 and 2019 to 2046, respectively.

Credit Ratings

Our continued access to the debt capital markets and to new financing facilities, as well as our borrowing costs, depend on multiple factors, including market conditions, our operating performance and maintaining strong credit ratings. As of September 30, 2019, our credit ratings were BBB+, Baa2 and BBB by Standard & Poor’s Ratings Services, Moody’s Investors Service and Fitch Ratings, Inc., respectively. If our credit ratings were downgraded, especially any downgrade to below investment grade, our ability to access the debt markets with the same flexibility that we have experienced historically, our cost of funds and other terms for new debt issuances, could be adversely impacted.

Intended Uses of Cash

We intend to use excess cash on hand and cash from operating activities to fund capital expenditures, acquisitions, dividend payments, share repurchases and debt repayments. Debt repayments may include purchases of our outstanding indebtedness in the secondary market or otherwise. We believe our excess cash, cash from operating activities and our availability to draw from our Credit Facility provide us with sufficient financial resources to meet our anticipated capital requirements and maturing obligations as they come due.

We may choose to voluntarily retire certain portions of our outstanding debt before their maturity dates using cash from operations or additional borrowings. We also may explore opportunities in capital markets to fund redemptions should market conditions be favorable. Early extinguishment of debt will result in an impairment charge in the period in which the debt is repaid.

Off-Balance Sheet Arrangements

We have no off-balance sheet debt or similar obligations, other than short-term operating leases and financial assurances, which are not classified as debt. We have no transactions or obligations with related parties that are not disclosed, consolidated into or reflected in our reported financial position or results of operations. We have not guaranteed any third-party debt.

Seasonality and Severe Weather

Our operations can be adversely affected by periods of inclement or severe weather, which could increase the volume of waste collected under our existing contracts (without corresponding compensation), delay the collection and disposal of waste, reduce the volume of waste delivered to our disposal sites, or delay the construction or expansion of our landfills and other facilities. Our operations also can be favorably affected by severe weather, which could increase the volume of waste in situations where we are able to charge for our additional services.

Contingencies

For a description of our commitments and contingencies, see Note 6, Landfill and Environmental Costs, Note 9, Income Taxes, and Note 15, Commitments and Contingencies, to our unaudited consolidated financial statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q.

Critical Accounting Judgments and Estimates

We identified and discussed our critical accounting judgments and estimates in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018. Although we believe our estimates and judgments are reasonable, they are based upon information available at the time the judgment or estimate is made. Actual results may differ significantly from estimates under different assumptions or conditions.

New Accounting Pronouncements

For a description of new accounting standards that may affect us, see Note 1, Basis of Presentation, to our unaudited consolidated financial statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Fuel Price Risk

Fuel costs represent a significant operating expense. When economically practical, we may enter into new fuel hedges, renew contracts, or engage in other strategies to mitigate market risk. As of September 30, 2019, we had no fuel hedges in place. While we charge fuel recovery fees to a majority of our customers, we are unable to charge such fees to all customers.

At current consumption levels, we believe a twenty-cent per gallon change in the price of diesel fuel would change our fuel costs by approximately $26 million per year. Offsetting these changes in fuel expense would result in changes in our fuel recovery fee charged to our customers. At current participation rates, we believe a twenty-cent per gallon change in the price of diesel fuel would change our fuel recovery fee by approximately $25 million per year.

Our operations also require the use of certain petrochemical-based products (such as liners at our landfills) whose costs may vary with the price of petrochemicals. An increase in the price of petrochemicals could increase the cost of those products, which would increase our operating and capital costs. We also are susceptible to increases in indirect fuel recovery fees from our vendors.

Our fuel costs were $283.1 million during the nine months ended September 30, 2019, or 3.7% of revenue, compared to $289.7 million during the comparable period in 2018, or 3.9% of revenue.

Commodities Price Risk

We market recovered materials such as old corrugated containers and old newsprint from our recycling processing centers. Changes in market supply and demand for recycled commodities causes volatility in commodity prices. We have previously entered into derivative instruments such as swaps and costless collars designated as cash flow hedges to manage our exposure to changes in prices of these commodities. As of September 30, 2019, we had no recycling commodity hedges in place.

At current volumes and mix of materials, we believe a $10 per ton change in the price of recycled commodities would change both annual revenue and operating income by approximately $18 million.

Revenue from recycling processing and commodity sales during the nine months ended September 30, 2019 and 2018 was $213.2 million and $219.9 million, respectively.

Interest Rate Risk

We are subject to interest rate risk on our variable rate long-term debt. Additionally, we enter into various interest rate swap agreements with the goal of reducing overall borrowing costs and increasing our floating interest rate exposure, as well as interest rate locks to manage exposure to fluctuations in anticipation of future debt issuances. Our interest rate swap and lock contracts have been authorized pursuant to our policies and procedures. We do not use financial instruments for trading purposes and are not a party to any leveraged derivatives.

As of September 30, 2019, we had $1,254.6 million of floating rate debt and $300.0 million of floating interest rate swap contracts. If interest rates increased or decreased by 100 basis points on our variable rate debt, annualized interest expense and net cash payments for interest would increase or decrease by approximately $16 million. This analysis does not reflect the effect that interest rates would have on other items, such as new borrowings and the impact on the economy. See Note 7, Debt, of the notes to our unaudited consolidated financial statements in Item 1 of Part I of this Form 10-Q for further information regarding how we manage interest rate risk.

ITEM 4.    CONTROLS AND PROCEDURES.

Disclosure Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e), and 15d-15(e)) as of the end of the period covered by this Form 10-Q. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Form 10-Q.

Changes in Internal Control Over Financial Reporting

Based on an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, there has been no change in our internal control over financial reporting during the period covered by this Form 10-Q identified in connection with that evaluation, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

In July 2019, we acquired all of the issued and outstanding shares of Southern Tank Leasing, Inc., Tidal Tank, Inc. and Bealine Service Company, Inc. (collectively Sprint). As permitted by the SEC Staff interpretive guidance for newly acquired businesses, management's assessment of our internal control over financial reporting as of September 30, 2019 did not include an assessment of those disclosure controls and procedures that are subsumed by internal control over financial reporting as it relates to the Sprint acquisition. We will continue the process of implementing internal controls over financial reporting for Sprint. As of September 30, 2019, assets excluded from management's assessment totaled $141.8 million and contributed less than 1% of revenue to our unaudited consolidated financial statements for the three and nine months ended September 30, 2019.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

General Legal Proceedings

We are subject to extensive and evolving laws and regulations and have implemented safeguards to respond to regulatory requirements. In the normal course of our business, we become involved in legal proceedings. Some may result in fines, penalties or judgments against us, or settlements, which may impact earnings and cash flows for a particular period. Although we cannot predict the ultimate outcome of any legal matter with certainty, we do not believe the outcome of any of our pending legal proceedings will have a material adverse impact on our consolidated financial position, results of operations or cash flows.

As used herein, the term legal proceedings refers to litigation and similar claims against us and our subsidiaries, excluding: (1) ordinary course accidents, general commercial liability and workers' compensation claims, which are covered by insurance programs, subject to customary deductibles, and which, together with self-insured employee health care costs, are discussed in Note 5, Other Liabilities, to our unaudited consolidated financial statements in Item 1 of Part I of this Form 10-Q; and (2) environmental remediation liabilities, which are discussed in Note 6, Landfill and Environmental Costs, to our unaudited consolidated financial statements in Item 1 of Part I of this Form 10-Q.

We accrue for legal proceedings when losses become probable and reasonably estimable. We have recorded an aggregate accrual of approximately $19 million relating to our outstanding legal proceedings as of September 30, 2019. As of the end of each applicable reporting period, we review each of our legal proceedings and, where it is probable that a liability has been incurred, we accrue for all probable and reasonably estimable losses. Where we are able to reasonably estimate a range of losses we may incur with respect to such a matter, we record an accrual for the amount within the range that constitutes our best estimate. If we are able to reasonably estimate a range but no amount within the range appears to be a better estimate than any other, we use the amount that is the low end of such range. If we had used the high ends of such ranges, our aggregate potential liability would be approximately $15 million higher than the amount recorded as of September 30, 2019.

Legal Proceedings over Certain Environmental Matters Involving Governmental Authorities with Possible Sanctions of $100,000 or More

Item 103 of the SEC's Regulation S-K requires disclosure of certain environmental matters when a governmental authority is a party to the proceedings and the proceedings involve potential monetary sanctions unless we reasonably believe the monetary sanctions will not equal or exceed $100,000. We are disclosing the following matters in accordance with that requirement:

Pine Avenue Landfill Matter

On December 20, 2016, the EPA issued a Finding of Violation (FOV) to Allied Waste Niagara Falls Landfill, LLC (Allied-Niagara). The FOV alleges violations of the Clean Air Act and associated regulations relating to operation of Allied-Niagara’s Pine Avenue Landfill in Niagara County, New York. On October 16, 2017, Allied-Niagara received a civil penalty demand from the EPA. The demand proposes a penalty of $0.6 million or $2.5 million, depending on the results of requested sampling analysis at the site. Allied-Niagara is in discussions concerning a resolution to the FOV, including the amount of the penalty.

West Contra Costa Sanitary Landfill Matters

The West Contra Costa Sanitary Landfill is a closed landfill formerly operated by West Contra Costa Sanitary Landfill, Inc. (WCCSL). The top deck area of the closed landfill is being utilized for a composting operation. In 2017, the Contra Costa County Health Department and the Bay Area Air Quality Management District requested that the Contra Costa County District Attorney’s Office (DA) initiate a civil enforcement action against WCCSL with respect to Notices of Violation (NOVs) from 2016 and 2017 for issues including alleged offsite odors from the composting operation and fire events in compost curing piles (the DA matter). In 2017 and 2018, the California State Water Resources Control Board (Water Board) issued three NOVs alleging that operations at the closed landfill violated stormwater and waste discharge requirements permits (the Water Board matter). In September 2018, we received separate penalty demands from the DA and the Water Board, totaling approximately $1.2 million in civil penalties and enforcement costs. WCCSL has settled the DA matter and is in discussions concerning a resolution of the Water Board matter.

ITEM 1A. RISK FACTORS.

Our material risk factors are disclosed in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2018. There have been no material changes during the nine months ended September 30, 2019 from or updates to the risk factors discussed in Part I, Item 1A, Risk Factors, of our 2018 Annual Report on Form 10-K.

a.In October 2017, our Board of Directors added $2.0 billion to the existing share repurchase authorization that now extends through December 31, 2020. Share repurchases under the program may be made through open market purchases or privately negotiated transactions in accordance with applicable federal securities laws. While the Board of Directors has approved the program, the timing of any purchases, the prices and the number of shares of common stock to be purchased will be determined by our management, at its discretion, and will depend upon market conditions and other factors. The share repurchase program may be extended, suspended or discontinued at any time. As of September 30, 2019, there were less than 0.1 million repurchased shares pending settlement, resulting in an associated $0.1 million of share repurchases unpaid and included within other accrued liabilities.

a.The total number of shares purchased as part of the publicly announced program were all purchased pursuant to the October 2017 authorization.

b.Shares that may be purchased under the program exclude shares of common stock that may be surrendered to satisfy statutory minimum tax withholding obligations in connection with the vesting of restricted stock units and performance stock units issued to employees.
