Accounting Policies [Abstract]
Basis of Presentation	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, 2019. 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, landfill 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, 2019. Our actual results may differ significantly from our estimates. In March 2020, the World Health Organization declared the outbreak of a new strain of coronavirus (COVID-19) a pandemic. The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains and created significant volatility and disruption of financial markets. The full extent of the impact of the COVID-19 pandemic on our operations and financial performance will depend on future developments, including the duration and spread of the pandemic, all of which are uncertain and cannot be predicted at this time. An extended period of economic disruption associated with the COVID-19 pandemic could materially and adversely affect our business, results of operations, access to sources of liquidity and financial condition. Both national and local government agencies have implemented steps with the intent to slow the spread of the virus, including shelter-in-place orders and the mandatory shutdown of certain businesses. During this time, we continued to provide essential services to our customers. In mid-March 2020, certain customers in our small- and large-container businesses began adjusting their service levels, which included a decrease in the frequency of pickups or a temporary pause in service. In addition, we experienced a decline in volumes disposed at certain of our landfills and transfer stations. As service levels decreased, we also experienced a decrease in certain costs of our operations which are variable in nature. This decline in service activity peaked in the first half of April and gradually improved thereafter as local economies began to gradually reopen and customers began to resume service. Large outbreaks and resurgences of COVID-19 in various regions may result in a reinstitution of certain restrictions. The demand for our environmental services business depends on the continued demand for, and production of, oil and natural gas in certain shale basins located in the United States. During the nine months ended September 30, 2020, the value of crude oil and natural gas declined to historic lows, resulting in a decrease in rig counts and drilling activity that led to a year-over-year decrease in revenue from our environmental services business. Further and/or sustained declines in the level of production activity may result in an unfavorable change to the long-term strategic outlook for our environmental services business that could result in the recognition of impairment charges on intangible assets and property and equipment associated with this business. On at least a quarterly basis, we will continue to monitor the effect of the evolving COVID-19 pandemic on our business and review our estimates for recoverability of assets used in certain of our operations that are related to strategic investments. In April 2020, we launched our Committed to Serve initiative which was intended to help our employees, customers and communities across the United States. We committed $20 million to support frontline employees and their families, as well as small business customers in the local communities we serve. In addition to this initiative, we have experienced an increase in certain costs of doing business as a direct result of the COVID-19 pandemic, including costs for additional safety equipment and hygiene products and increased facility and equipment cleaning. These costs, which we refer to as business resumption costs, are intended to assist in protecting the safety of our frontline employees as we continue to provide an essential service to our customers. We also incurred incremental costs for expanding certain aspects of our existing healthcare programs and guaranteeing certain frontline employees a minimum hourly work week regardless of service decreases. We expect to incur similar costs throughout 2020, and potentially into future years. The magnitude of the costs we expect to incur throughout the remainder of the year cannot be predicted at this time due to the various uncertainties surrounding the pandemic (e.g., its duration and spread). New Accounting Pronouncements Accounting Standards Adopted Effective January 1, 2020, we adopted the following accounting standards updates (ASUs) as issued by the Financial Accounting Standards Board (FASB): ASU Effective Date ASU 2016-13 Credit Losses (Topic 326) January 1, 2020 ASU 2018-13 Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (Topic 820) January 1, 2020 Credit Losses Effective January 1, 2020, we adopted ASU 2016-13, Credit Losses Topic 326 (ASU 2016-13 or the new credit losses standard) using the modified retrospective approach. The comparative periods have not been restated and continue to be reported under the accounting standard in effect for those periods. The new credit losses standard amends the impairment model to use a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Our adoption of ASU 2016-13 did not have a material impact on our consolidated financial statements for the nine months ended September 30, 2020, and we did not recognize a cumulative effect adjustment to retained earnings as of January 1, 2020. To assist in quantifying the impact on our consolidated financial statements and supplementing our existing disclosures, we identified financial assets measured at an amortized cost basis in our consolidated balance sheet and evaluated the collectability considerations based on an expected credit loss assessment. We are exposed to credit losses primarily through customer receivables generated from the collection, transfer and disposal of non-hazardous solid waste and environmental services we provide our customers as well as the recovering and sale of certain recyclable materials. We perform ongoing credit evaluations of our customers, but generally do not require collateral to support customer receivables. We establish an allowance for doubtful accounts based on various factors including the age of receivables outstanding, historical trends, economic conditions and other information. We also review outstanding balances on an account-specific basis based on the credit risk of the customer. We determined that all of our accounts receivable share similar risk characteristics. We monitor our credit exposure on an ongoing basis and assess whether assets in the pool continue to display similar risk characteristics. The consolidated statement of income for the nine months ended September 30, 2020 reflects the measurement of credit losses for newly recognized financial assets as well as any changes to historical financial assets. The following table reflects the activity in our allowance for doubtful accounts during the nine months ended September 30, 2020. Allowance for Doubtful Accounts and Other Balance as of December 31, 2019 $ 34.0 Additions charged to expense 22.0 Accounts written-off (22.4) Balance as of September 30, 2020 $ 33.6 We continue to apply our historical loss rate assumptions and reserve against outstanding balances on an account-specific basis as we assess the collectability of our receivables. In certain situations, we may offer credit extensions to our customers as they navigate the uncertain economic environment brought about by the COVID-19 pandemic. In accordance with our accounting policy, we are actively monitoring the credit risk of our specific customers, age of receivables outstanding, recent collection trends and general economic conditions to evaluate the risk of credit loss. Fair Value Measurement Effective January 1, 2020, we adopted the FASB's 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 intends to increase the consistency and comparability of fair value measurements used in financial reporting through eliminating, modifying, and adding certain disclosure requirements within Topic 820. The adoption of ASU 2018-13 did not have a material impact on our consolidated financial statements for the nine months ended September 30, 2020. Accounting Standards Updates Issued but not yet Adopted 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. Simplifying the Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12). ASU 2019-12 attempts to simplify aspects of accounting for franchise taxes and enacted changes in tax laws or rates, and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The amended guidance contains a model under which an entity can consider a list of factors in determining whether the step-up in tax basis of goodwill is related to the business combination that caused the initial recognition of goodwill or to a separate transaction. ASU 2019-12 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. Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (ASU 2020-04). ASU 2020-04 provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in ASU 2020-04 provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. ASU 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. We are currently assessing the effect this guidance may have on our consolidated financial statements.

Accordingly, certain of the purchase price allocations are preliminary and subject to change. 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 2020, we continued to acquire 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 capital contributions of $56.7 million and $14.1 million, which were recorded to other assets in our September 30, 2020 and 2019 consolidated balance sheets, respectively. During the three and nine months ended September 30, 2020, we reduced the carrying value of these investments by $8.2 million and $30.8 million, respectively, and during the three and nine months ended September 30, 2019, we reduced the carrying value of these investments by $4.0 million and $27.2 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 2019, we incurred costs related to the redesign of certain back-office software systems, which continued into 2020. In addition, in July 2020, we eliminated certain positions, primarily related to our back-office support functions, in response to the COVID-19 pandemic. During the three and nine months ended September 30, 2020, we incurred restructuring charges of $9.8 million and $15.8 million, respectively, that primarily related to these restructuring efforts. 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 the redesign of certain back-office software systems. During the nine months ended September 30, 2020 and 2019, we paid $11.9 million and $7.9 million, respectively, related to these restructuring efforts. During the remainder of 2020, we expect to incur additional restructuring charges of approximately $3 million to $5 million primarily related to the redesign of certain of our back-office software systems. Substantially all of these restructuring charges will be recorded in our corporate segment.

Environmental Remediation Obligations [Abstract]
Landfill and Environmental Costs	LANDFILL AND ENVIRONMENTAL COSTS As of September 30, 2020, we owned or operated 188 active solid waste landfills with total available disposal capacity estimated to be 5.0 billion in-place cubic yards. Additionally, we had post-closure responsibility for 128 closed landfills. Accrued Landfill and Environmental Costs A summary of accrued landfill and environmental liabilities as of September 30, 2020 and December 31, 2019 follows: 2020 2019 Landfill final capping, closure and post-closure liabilities $ 1,362.7 $ 1,335.6 Environmental remediation 476.0 500.2 Total accrued landfill and environmental costs 1,838.7 1,835.8 Less: current portion (123.4) (132.6) Long-term portion $ 1,715.3 $ 1,703.2 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, 2020 and 2019: 2020 2019 Asset retirement obligation liabilities, beginning of year $ 1,335.6 $ 1,292.0 Non-cash additions 32.0 32.9 Acquisitions, net of divestitures and other adjustments (14.3) 0.3 Asset retirement obligation adjustments (13.5) 0.7 Payments (39.5) (47.7) Accretion expense 62.4 61.4 Asset retirement obligation liabilities, end of period 1,362.7 1,339.6 Less: current portion (65.2) (80.9) Long-term portion $ 1,297.5 $ 1,258.7 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. 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, 2020 would be approximately $365 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, 2020 and 2019: 2020 2019 Environmental remediation liabilities, beginning of year $ 500.2 $ 540.2 Net adjustments charged to expense (1.2) (9.6) Payments (39.8) (29.4) Accretion expense (non-cash interest expense) 13.9 14.3 Acquisitions, net of divestitures and other adjustments 2.9 0.1 Environmental remediation liabilities, end of period 476.0 515.6 Less: current portion (58.2) (72.3) Long-term portion $ 417.8 $ 443.3 Bridgeton Landfill. During the nine months ended September 30, 2020, we paid $19.8 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, 2020, the remediation liability recorded for this site was $124.7 million, of which approximately $4 million is expected to be paid during the remainder of 2020. We believe the remaining reasonably possible high end of our range would be approximately $163 million higher than the amount recorded as of September 30, 2020. During the nine months ended September 30, 2020, we recognized a favorable insurance recovery of $10.8 million related to our closed Bridgeton Landfill as a reduction of remediation expenses in our consolidated statement of income for the applicable period. 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-

We paid a cash premium of $34.0 million and incurred a non-cash charge related to the unamortized deferred issuance costs of $0.5 million. Credit Facilities The 364-Day Credit Facility In August 2020, we entered into a $1.0 billion 364-day unsecured revolving credit facility (the 364-Day Credit Facility), which matures in August 2021. At our option, borrowings under the 364-Day 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 364-Day Credit Facility agreement). The 364-Day Credit Facility is subject to facility fees based on applicable rates defined in the 364-Day Credit Facility agreement and the aggregate commitment, regardless of usage. Availability under our 364-Day Credit Facility totaled $1.0 billion as of September 30, 2020. The 364-Day Credit Facility can be used for working capital, capital expenditures, acquisitions, and other general corporate purposes. The 364-Day 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, 2020, we had no borrowings outstanding under our 364-Day Credit Facility. The Credit Facility In 2018, we entered into a $2.25 billion unsecured revolving credit facility (the Credit Facility), which 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 $1,857.8 million and $1,696.9 million as of September 30, 2020 and December 31, 2019, 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, 2020, we had no borrowings under our Credit Facility, and as of December 31, 2019, we had $184.4 million of borrowings under our Credit Facility. We had $376.5 million and $351.4 million of letters of credit outstanding under our Credit Facility as of September 30, 2020 and December 31, 2019, respectively. In July 2020, we executed an amendment to the Credit Facility agreement to increase flexibility and reduce restrictions, in particu lar, for future acquisitions. Effective June 30, 2020 , the amendment eliminated the consolidated interest coverage ratio and revised the sole remaining financial covenant, total debt to EBITDA ratio. Uncommitted Credit Facility We also have an Uncommitted Credit Facility, which bears interest at LIBOR, plus an applicable margin. 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. As of September 30, 2020, we had no borrowings outstanding under our Uncommitted Credit Facility, and as of December 31, 2019, we had $11.6 million of borrowings outstanding under our Uncommitted Credit Facility. Senior Notes and Debentures In August 2020, we issued $650.0 million of 1.450% senior notes due 2031 (the 1.450% Notes). We used the net proceeds to redeem all $600.0 million of the outstanding 5.250% senior notes due November 2021 plus a make-whole premium of $34.0 million. The remaining proceeds were used for general corporate purposes. In February 2020, we issued $600.0 million of 2.300% senior notes due 2030 (the 2.300% Notes) and $400.0 million of 3.050% senior notes due 2050 (the 3.050% Notes). We used the net proceeds from the 2.300% Notes and 3.050% Notes to repay $850.0 million of 5.000% senior notes that matured in March 2020. The remaining proceeds were used to repay amounts outstanding under our unsecured credit facilities as well as for general corporate purposes. Our senior notes and debentures are general unsecured obligations. Interest is payable semi-annually. 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, 2020, 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, 2020 and December 31, 2019, the interest rate swap agreements are reflected at their fair value of $19.9 million and $10.7 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. We recognized net interest income of $1.8 million and $0.3 million during the three months ended September 30, 2020 and 2019, respectively, and net interest income of $3.8 million and $0.5 million during the nine months ended September 30, 2020 and 2019, respectively, related to net settlements for these interest rate swap agreements, which is included as an offset to interest expense in our consolidated statements of income. For the three months ended September 30, 2020 and 2019, we recognized a gain of $2.1 million and a loss of $1.1 million, respectively, on the change in fair value of the hedged senior notes with an offsetting loss of $1.8 million and an offsetting gain of $1.4 million, respectively, on the related interest rate swaps, both attributable to changes in the benchmark interest rate. For the nine months ended September 30, 2020 and 2019, we recognized losses of $7.5 million and $10.0 million, respectively, on the change in fair value of the hedged senior notes, with offsetting gains of $9.3 million and $10.5 million, respectively, on the related interest rate swaps, both attributable to changes in the benchmark interest rate. The difference of these fair value changes for the three and nine months ended September 30, 2020 and 2019 was recorded directly in earnings as an adjustment to interest expense in our consolidated statements of income. For further detail regarding the effect of our fair value hedging on interest expense, refer to Note 11, Financial Instruments , of the notes to our unaudited consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q. Cash Flow Hedges We have historically entered into multiple swap agreements designated as cash flow hedges to manage exposure to fluctuations in interest rates in anticipation of planned future issuances of senior notes. Upon the expected issuance of senior notes, we terminate the interest rate locks and settle with our counterparties. These transactions were accounted for as cash flow hedges. All of our cash flow hedges settled on or before September 30, 2020, thus there is no related asset or liability as of September 30, 2020. As of December 31, 2019, our interest rate lock agreements had an aggregate notional value of $575.0 million, with fixed interest rates ranging from 1.330% to 3.000%. 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 December 31, 2019 were assets of $3.6 million, which were recorded in prepaid expenses and other current assets in our consolidated balance sheet and liabilities of $15.7 million, which were recorded in other accrued liabilities and other long-term liabilities in our consolidated balance sheet. Total unrealized loss recognized in other comprehensive income for interest rate locks was $0.2 million and $11.9 million, net of tax, for the three months ended September 30, 2020 and 2019, respectively. Total unrealized loss recognized in other comprehensive income for interest rate locks was $22.5 million and $43.0 million, net of tax, for the nine months ended September 30, 2020 and 2019, respectively. As of September 30, 2020 and December 31, 2019, our previously terminated interest rate locks were recorded as components of accumulated other comprehensive loss, net of tax of $33.0 million and $4.7 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. Over the next 12 months, we expect to amortize approximately $5.3 million, net of tax, from accumulated other comprehensive loss to interest expense as a yield adjustment of our senior notes. For further detail regarding the effect of our cash flow hedging on interest expense, refer to Note 11, Financial Instruments , of the notes to our unaudited consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q. Derivative Contracts Contemporaneously with the issuance of our 2.300% Notes in February 2020, we amended interest rate lock agreements with an aggregate notional value of $550.0 million, extending the mandatory maturity date from 2020 to 2030, and dedesignated them as cash flow hedges (the 2020 Extended Interest Rate Locks). Contemporaneously with the issuance of our 2.500% Notes in August 2019, we amended interest rate lock agreements with an aggregate notional value of $375.0 million, extending the mandatory maturity date from 2019 to 2024, and dedesignated them as cash flow hedges (collectively with the 2020 Extended Interest Rate Locks referred to as the Extended Interest Rate Locks). There was no ineffectiveness recognized in the dedesignation of these cash flow hedges. In addition, we entered into offsetting interest rate swaps to offset future exposures to fair value fluctuations of the Extended Interest Rate Locks (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, 2020 and December 31, 2019, the fair values of the Extended Interest Rate Locks were liabilities of $110.2 million and $22.2 million, respectively, which were included in other long-term liabilities in our consolidated balance sheets, and the fair values of the Offsetting Interest Rate Swaps were assets of $63.3 million and $2.9 million, respectively, and were included in other assets in our consolidated balance sheets. For the three and nine months ended September 30, 2020, we recognized gains of $8.6 million and losses of $(62.9) million, respectively, on the change in fair value of the Extended Interest Rate Locks, with offsetting losses of $(8.6) million and offsetting gains of $60.7 million, respectively, 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 statements of income. Tax-Exempt Financings As of September 30, 2020, we had $1,119.6 million of certain variable rate tax-exempt financings outstanding with maturities ranging from 2020 to 2050. As of December 31, 2019, we had $1,116.2 million of certain variable rate tax-exempt financings outstanding with maturities ranging from 2020 to 2049. During the second quarter of 2020, we issued $60.0 million of 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. All of our tax-exempt financings are remarketed either quarterly or semiannually 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. If the remarketing agent is unable to remarket our bonds, the remarketing agent can put the bonds to us. In the event of a failed remarketing, we currently have availability under our $2.25 billion unsecured revolving credit facility to fund these bonds until they are remarketed successfully. Accordingly, we have classified these borrowings as long-term in our consolidated balance sheets as of September 30, 2020 and December 31, 2019. Finance Leases We had finance lease liabilities of $210.1 million as of September 30, 2020 with maturities ranging from 2020 to 2063 . We had finance lease liabilities of $119.3 million as of December 31, 2019 with maturities ranging from 2020 to 2049 . In September 2020, we entered into an agreement to extend the term of one of our landfill finance leases by approximately 43 years, or through the end of the landfill's site life. Accordingly, we recognized an incremental finance lease obligation of $90.4 million as of September 30, 2020.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Our effective tax rate, exclusive of non-controlling interests, for the nine months ended September 30, 2020 and 2019 was 22.1% and 22.5%, respectively. Our effective tax rates reflected benefits from investments in solar energy assets qualifying for tax credits under Section 48 of the Internal Revenue Code, excess tax benefits under ASU 2016-19 and the realization of additional federal and state benefits as well as adjustments to deferred taxes due to the completion of our tax returns. Cash paid for income taxes was $34.2 million for the nine months ended September 30, 2020 and a net refund of $4.3 million for the same period in 2019. The net refund received for the nine months ended September 30, 2019 was due to the receipt of funds from amended tax returns. 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 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. During the nine months ended September 30, 2020, we began analyzing the utilization of certain of our tax attributes given recent acquisitions, divestitures and a long-term strategic review of our operations. We expect to conclude our efforts in the fourth quarter of 2020 and may reduce our valuation allowance by approximately $0 million to $20 million at December 31, 2020. 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, 2020, the valuation allowance associated with our state loss carryforwards was approximately $69 million. We are subject to income tax in the United States, 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 by the Internal Revenue Service for tax years 2015 through 2017, as well as various state and local taxing authorities for tax years 2012 through 2019. We believe 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, 2020, 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, 2020, we accrued a liability for penalties of $0.3 million and a liability for interest (including interest on penalties) of $12.4 million related to our uncertain tax positions.

As of September 30, 2019, less than 0.1 million repurchased shares were pending settlement. In October 2017, our Board of Directors added $2.0 billion to the previous share repurchase authorization, which continues through December 31, 2020. In October 2020, our Board of Directors approved a $2.0 billion share repurchase authorization effective starting January 1, 2021 and extending through December 31, 2023. 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, 2020, the remaining authorized purchase capacity under our October 2017 repurchase program was $605.8 million. Dividends In July 2020, our Board of Directors approved a quarterly dividend of $0.425 per share. Cash dividends declared were $393.3 million for the nine months ended September 30, 2020. As of September 30, 2020, we recorded a quarterly dividend payable of $135.4 million to shareholders of record at the close of business on October 1, 2020. 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, 2020 and 2019 are calculated as follows (in thousands, except per share amounts): Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 Basic earnings per share: Net income attributable to Republic Services, Inc. $ 260,000 $ 298,300 $ 731,800 $ 784,000 Weighted average common shares outstanding 319,201 320,633 319,275 321,544 Basic earnings per share $ 0.81 $ 0.93 $ 2.29 $ 2.44 Diluted earnings per share: Net income attributable to Republic Services, Inc. $ 260,000 $ 298,300 $ 731,800 $ 784,000 Weighted average common shares outstanding 319,201 320,633 319,275 321,544 Effect of dilutive securities: Options to purchase common stock 41 368 68 437 Unvested RSU awards 169 276 168 248 Unvested PSU awards 323 433 313 415 Weighted average common and common equivalent shares outstanding 319,734 321,710 319,824 322,644 Diluted earnings per share $ 0.81 $ 0.93 $ 2.29 $ 2.43 During the three months ended September 30, 2020, there were less than 0.1 million antidilutive securities outstanding, and during the nine months ended September 30, 2020, there were 0.1 million antidilutive securities outstanding.

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, current investments, accounts payable and certain other accrued liabilities, approximates fair value because of their short-term nature. As of September 30, 2020 and December 31, 2019, our assets and liabilities that are measured at fair value on a recurring basis include the following: September 30, 2020 Fair Value Carrying Amount Total Quoted Significant Significant Assets: Money market mutual funds $ 46.2 $ 46.2 $ 46.2 $ — $ — Bonds - restricted cash and marketable securities and other assets 63.1 63.1 — 63.1 — Interest rate swaps - other assets 19.9 19.9 — 19.9 — Other derivative assets - other assets 63.3 63.3 — 63.3 — Total assets $ 192.5 $ 192.5 $ 46.2 $ 146.3 $ — Liabilities: Other derivative liabilities - other long-term liabilities $ 110.2 $ 110.2 $ — $ 110.2 $ — Contingent consideration - other accrued liabilities and other long-term liabilities 70.9 70.9 — — 70.9 Total liabilities $ 181.1 $ 181.1 $ — $ 110.2 $ 70.9 December 31, 2019 Fair Value Carrying Amount Total Quoted Significant Significant Assets: Money market mutual funds $ 43.0 $ 43.0 $ 43.0 $ — $ — Bonds - restricted cash and marketable securities and other assets 51.6 51.6 — 51.6 — Interest rate swaps - other assets 10.7 10.7 — 10.7 — Other derivative assets - other assets 2.9 2.9 — 2.9 — Interest rate locks - prepaid expenses and other current assets 3.6 3.6 — 3.6 — Total assets $ 111.8 $ 111.8 $ 43.0 $ 68.8 $ — Liabilities: Other derivative liabilities - other long-term liabilities $ 22.2 $ 22.2 $ — $ 22.2 $ — Interest rate locks - other accrued liabilities and other long-term liabilities 15.7 15.7 — 15.7 — Contingent consideration - other accrued liabilities and other long-term liabilities 72.0 72.0 — — 72.0 Total liabilities $ 109.9 $ 109.9 $ — $ 37.9 $ 72.0 Total Debt As of September 30, 2020 and December 31, 2019, the carrying value of our total debt was $8.8 billion and $8.7 billion, respectively, and the fair value of our total debt was $9.9 billion and $9.4 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, 2020 and December 31, 2019. See Note 7, Debt , for further information related to our debt. 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, 2020, the Sonoma contingent consideration represents the fair value of $64.5 million payable to the County of Sonoma based on the achievement of future annual tonnage targets through the expected remaining capacity of the landfill. 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 $75 million and $165 million. During the nine months ended September 30, 2020, 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. In 2017, we recognized additional contingent consideration associated with the acquisition of a landfill. As of September 30, 2020, the contingent consideration of $3.8 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, 2020, 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. In June 2019, we recognized additional contingent consideration associated with the acquisition of a collection business. As of September 30, 2020, the contingent consideration of $2.6 million represents the fair value of amounts payable to the seller based on annual volume of tons collected from certain customers of the business. During the nine months ended September 30, 2020, the activity in the contingent consideration liability included accretion. There were no changes to the estimate of fair value.

The following table disaggregates our revenue by service line for the three and nine months ended September 30, 2020 and 2019 (in millions of dollars and as a percentage of revenue): Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 Collection: Residential $ 581.2 22.6 % $ 574.4 21.7 % $ 1,723.3 22.8 % $ 1,701.8 22.0 % Small-container 773.7 30.1 799.1 30.2 2,321.8 30.6 2,369.0 30.7 Large-container 553.1 21.5 583.6 22.1 1,606.8 21.2 1,688.2 21.9 Other 13.1 0.5 11.7 0.4 38.0 0.5 34.2 0.4 Total collection 1,921.1 74.7 1,968.8 74.4 5,689.9 75.1 5,793.2 75.0 Transfer 352.4 348.0 1,004.8 987.6 Less: intercompany (190.9) (193.1) (556.9) (558.6) Transfer, net 161.5 6.3 154.9 5.8 447.9 5.9 429.0 5.6 Landfill 597.3 604.2 1,719.6 1,747.0 Less: intercompany (263.4) (264.4) (763.9) (773.0) Landfill, net 333.9 13.0 339.8 12.8 955.7 12.6 974.0 12.6 Environmental services 24.1 0.9 57.8 2.2 101.0 1.3 143.6 1.8 Other: Recycling processing and commodity sales 75.0 2.9 68.6 2.6 216.2 2.9 213.3 2.8 Other non-core 56.5 2.2 57.0 2.2 169.7 2.2 169.6 2.2 Total other 131.5 5.1 125.6 4.8 385.9 5.1 382.9 5.0 Total revenue $ 2,572.1 100.0 % $ 2,646.9 100.0 % $ 7,580.4 100.0 % $ 7,722.7 100.0 % 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, 2019 was recognized as revenue during the nine months ended September 30, 2020 when the service was performed. See Note 12, Segment Reporting , for additional information regarding revenue by reportable segment. Revenue Recognition Our service obligations of a long-term nature, e.g., certain 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 only be recognized once the index is established for the period. 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, 2020 and December 31, 2019, we recognized $80.8 million and $83.1 million, respectively, of deferred contract costs and capitalized sales commissions. During the three and nine months ended September 30, 2020, we amortized $2.9 million and $9.1 million, respectively, of capitalized sales commissions to selling, general and administrative expenses and we amortized $1.6 million and $4.9 million, respectively, of other deferred contract costs as a reduction of revenue. During the three and nine months ended September 30, 2019, we amortized $2.9 million and $8.9 million, respectively, of capitalized sales commissions to selling, general and administrative expenses and we amortized $1.6 million and $4.6 million, respectively, of other deferred contract costs as a reduction of revenue. Effective January 1, 2020, we adopted ASU 2016-13. In accordance with the standard, we evaluated the impairment considerations for our deferred contract cost assets based on an expected credit loss assessment. We considered the impact of the COVID-19 pandemic on our business, noting no significant changes to our expected credit loss assessment.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	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 $25 million relating to our outstanding legal proceedings as of September 30, 2020. 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 $9 million higher than the amount recorded as of September 30, 2020. Multiemployer Pension Plans We participate in multiemployer pension plans that generally provide retirement benefits to participants of 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 the multiemployer pension plans in which we participate. We accrue for such events when losses become probable and reasonably estimable. In June 2020, we entered into an agreement with a certain multiemployer pension fund through which we transitioned from one plan into another plan managed by the same fund, thus creating a withdrawal event from the original plan. As a result of the withdrawal event, we recognized $31.6 million of withdrawal costs, which we paid in July 2020. The COVID-19 pandemic has created significant volatility and disruption of financial markets, which has negatively impacted companies across the globe. We will continue to monitor the Pension Protection Act zone status of the multiemployer pension plans in which we participate, noting that the current economic environment may impact certain contributing employers' ability to fulfill their obligations under the plans. We believe the largest risk is attributable to plans in the critical red zone, which are less than 65% funded. In the event other contributing employers default on their obligations under the plans, we could be required to adjust our estimates for these matters, which could have a material and adverse effect on our consolidated financial position, results of operations and cash flows. Restricted Cash and Marketable Securities Restricted cash and restricted cash equivalents are included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. Beginning-of-period and end-of-period cash, cash equivalents, restricted cash and restricted cash equivalents as presented in the statement of cash flows is reconciled as follows: September 30, 2020 December 31, 2019 September 30, 2019 December 31, 2018 Cash and cash equivalents $ 406.4 $ 47.1 $ 55.6 $ 70.5 Restricted cash and marketable securities 145.2 179.4 121.3 108.1 Less: restricted marketable securities (62.4) (49.1) (48.3) (45.3) Cash, cash equivalents, restricted cash and restricted cash equivalents $ 489.2 $ 177.4 $ 128.6 $ 133.3 Our restricted cash and marketable securities include, among other things, 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, restricted cash and marketable securities related to our insurance obligations, and restricted cash related to a payment for a certain maturing tax-exempt financing. The following table summarizes our restricted cash and marketable securities: September 30, 2020 December 31, 2019 Capping, closure and post-closure obligations $ 31.4 $ 30.6 Insurance 113.8 99.4 Payment for maturing tax-exempt financing — 49.4 Total restricted cash and marketable securities $ 145.2 $ 179.4 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.

Accounting Policies [Abstract]
Management's Estimates and Assumptions	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, landfill 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, 2019. Our actual results may differ significantly from our estimates. In March 2020, the World Health Organization declared the outbreak of a new strain of coronavirus (COVID-19) a pandemic. The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains and created significant volatility and disruption of financial markets. The full extent of the impact of the COVID-19 pandemic on our operations and financial performance will depend on future developments, including the duration and spread of the pandemic, all of which are uncertain and cannot be predicted at this time. An extended period of economic disruption associated with the COVID-19 pandemic could materially and adversely affect our business, results of operations, access to sources of liquidity and financial condition. Both national and local government agencies have implemented steps with the intent to slow the spread of the virus, including shelter-in-place orders and the mandatory shutdown of certain businesses. During this time, we continued to provide essential services to our customers. In mid-March 2020, certain customers in our small- and large-container businesses began adjusting their service levels, which included a decrease in the frequency of pickups or a temporary pause in service. In addition, we experienced a decline in volumes disposed at certain of our landfills and transfer stations. As service levels decreased, we also experienced a decrease in certain costs of our operations which are variable in nature. This decline in service activity peaked in the first half of April and gradually improved thereafter as local economies began to gradually reopen and customers began to resume service. Large outbreaks and resurgences of COVID-19 in various regions may result in a reinstitution of certain restrictions. The demand for our environmental services business depends on the continued demand for, and production of, oil and natural gas in certain shale basins located in the United States. During the nine months ended September 30, 2020, the value of crude oil and natural gas declined to historic lows, resulting in a decrease in rig counts and drilling activity that led to a year-over-year decrease in revenue from our environmental services business. Further and/or sustained declines in the level of production activity may result in an unfavorable change to the long-term strategic outlook for our environmental services business that could result in the recognition of impairment charges on intangible assets and property and equipment associated with this business. On at least a quarterly basis, we will continue to monitor the effect of the evolving COVID-19 pandemic on our business and review our estimates for recoverability of assets used in certain of our operations that are related to strategic investments. In April 2020, we launched our Committed to Serve initiative which was intended to help our employees, customers and communities across the United States. We committed $20 million to support frontline employees and their families, as well as small business customers in the local communities we serve. In addition to this initiative, we have experienced an increase in certain costs of doing business as a direct result of the COVID-19 pandemic, including costs for additional safety equipment and hygiene products and increased facility and equipment cleaning. These costs, which we refer to as business resumption costs, are intended to assist in protecting the safety of our frontline employees as we continue to provide an essential service to our customers. We also incurred incremental costs for expanding certain aspects of our existing healthcare programs and guaranteeing certain frontline employees a minimum hourly work week regardless of service decreases. We expect to incur similar costs throughout 2020, and potentially into future years. The magnitude of the costs we expect to incur throughout the remainder of the year cannot be predicted at this time due to the various uncertainties surrounding the pandemic (e.g., its duration and spread).
New Accounting Pronouncements	New Accounting Pronouncements Accounting Standards Adopted Effective January 1, 2020, we adopted the following accounting standards updates (ASUs) as issued by the Financial Accounting Standards Board (FASB): ASU Effective Date ASU 2016-13 Credit Losses (Topic 326) January 1, 2020 ASU 2018-13 Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (Topic 820) January 1, 2020 Credit Losses Effective January 1, 2020, we adopted ASU 2016-13, Credit Losses Topic 326 (ASU 2016-13 or the new credit losses standard) using the modified retrospective approach. The comparative periods have not been restated and continue to be reported under the accounting standard in effect for those periods. The new credit losses standard amends the impairment model to use a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Our adoption of ASU 2016-13 did not have a material impact on our consolidated financial statements for the nine months ended September 30, 2020, and we did not recognize a cumulative effect adjustment to retained earnings as of January 1, 2020. To assist in quantifying the impact on our consolidated financial statements and supplementing our existing disclosures, we identified financial assets measured at an amortized cost basis in our consolidated balance sheet and evaluated the collectability considerations based on an expected credit loss assessment. We are exposed to credit losses primarily through customer receivables generated from the collection, transfer and disposal of non-hazardous solid waste and environmental services we provide our customers as well as the recovering and sale of certain recyclable materials. We perform ongoing credit evaluations of our customers, but generally do not require collateral to support customer receivables. We establish an allowance for doubtful accounts based on various factors including the age of receivables outstanding, historical trends, economic conditions and other information. We also review outstanding balances on an account-specific basis based on the credit risk of the customer. We determined that all of our accounts receivable share similar risk characteristics. We monitor our credit exposure on an ongoing basis and assess whether assets in the pool continue to display similar risk characteristics. The consolidated statement of income for the nine months ended September 30, 2020 reflects the measurement of credit losses for newly recognized financial assets as well as any changes to historical financial assets. The following table reflects the activity in our allowance for doubtful accounts during the nine months ended September 30, 2020. Allowance for Doubtful Accounts and Other Balance as of December 31, 2019 $ 34.0 Additions charged to expense 22.0 Accounts written-off (22.4) Balance as of September 30, 2020 $ 33.6 We continue to apply our historical loss rate assumptions and reserve against outstanding balances on an account-specific basis as we assess the collectability of our receivables. In certain situations, we may offer credit extensions to our customers as they navigate the uncertain economic environment brought about by the COVID-19 pandemic. In accordance with our accounting policy, we are actively monitoring the credit risk of our specific customers, age of receivables outstanding, recent collection trends and general economic conditions to evaluate the risk of credit loss. Fair Value Measurement Effective January 1, 2020, we adopted the FASB's 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 intends to increase the consistency and comparability of fair value measurements used in financial reporting through eliminating, modifying, and adding certain disclosure requirements within Topic 820. The adoption of ASU 2018-13 did not have a material impact on our consolidated financial statements for the nine months ended September 30, 2020. Accounting Standards Updates Issued but not yet Adopted 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. Simplifying the Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12). ASU 2019-12 attempts to simplify aspects of accounting for franchise taxes and enacted changes in tax laws or rates, and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The amended guidance contains a model under which an entity can consider a list of factors in determining whether the step-up in tax basis of goodwill is related to the business combination that caused the initial recognition of goodwill or to a separate transaction. ASU 2019-12 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. Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (ASU 2020-04). ASU 2020-04 provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in ASU 2020-04 provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. ASU 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. We are currently assessing the effect this guidance may have on our consolidated financial statements.
