Legal, tax, information technology, human resources, certain finance and accounting and other administrative functions are included in our Corporate Entities segment.
The accompanying unaudited consolidated financial statements, which include the accounts of the Parent and our wholly-owned subsidiaries, have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). All significant intercompany accounts and transactions are eliminated in consolidation. Investments in entities in which we do not have a controlling financial interest are accounted for under either the equity method or the cost method of accounting, as appropriate. Our significant accounting policies are more fully discussed in Item 8, "Financial Statements and Supplementary Data" of our Annual Report on Form 10-K for the fiscal year ended December 31, 20202021 ("fiscal year 2020"2021"), which was filed with the SEC on February 19, 2021.18, 2022.
Preparation of our consolidated financial statements in accordance with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the accounting for and recognition and disclosure of assets, liabilities, equity, revenues and expenses. We must make these estimates and assumptions because certain information that we use is dependent on future events, cannot be calculated with a high degree of precision given the available data, or simply cannot be readily calculated. In the opinion of management, these consolidated financial statements include all adjustments, which include normal recurring and nonrecurring adjustments, necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented. The results for the three months ended March 31, 20212022 may not be indicative of the results for any other interim period or the entire fiscal year. The consolidated financial statements presented herein should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form 10-K for fiscal year 2020.
Recent Events
The global outbreak of the novel coronavirus ("COVID-19") pandemic has caused, and is expected to continue to cause, economic disruption across our geographic footprint and has adversely affected, and is expected to continue to adversely affect, our business. The COVID-19 pandemic negatively impacted our revenues starting at the end of the three months ended March 31, 2020, as many small business and construction collection customers required service level changes and volumes into our landfills declined due to lower economic activity. Although demand for services has improved as local economies begin to reopen as allowed by State Governments, our collection and disposal operations continued to be negatively impacted by lower volumes attributable to the COVID-19 pandemic in the three months ended March 31, 2021.
The COVID-19 pandemic has negatively impacted and is expected to continue to impact our business in other ways, as we have experienced and continue to experience increased costs as a result of the COVID-19 pandemic, including, but not limited to, higher costs associated with providing a safe working environment for our employees (such as increased costs associated with the protection of our employees, including costs for additional safety equipment, hygiene products and enhanced facility cleaning), employee impacts from illness, supporting a remote administrative workforce, community response measures, the inability of customers to continue to pay for services, and temporary facility closures of our customers. We have taken measures to reduce costs in other areas and preserve liquidity during this period of uncertainty. As of the date of this filing, we are unable to determine or predict the full extent of the continuing impact that the COVID-19 pandemic will have on our business, results of operations, liquidity and capital resources. Future developments, such as the possibility of continuing spread of COVID-19 across our geographic footprint, the rate of vaccinations, the severity and containment of certain COVID-19 variants along with the pace and extent to which the States in which we operate facilitate a return to normal economic and operation conditions are uncertain and cannot be predicted at this time.

3.    REVENUE RECOGNITION
Revenues associated with our solid waste operations are derived mainly from solid waste collection and disposal services, including landfill, transfer station and transportation services, landfill gas-to-energy services, and processing transfer and recycling services in the northeastern United States. Effective January 1, 2021, we reorganized the Resource Solutions operating segment, which includes our larger-scale recycling and commodity brokerage operations alongservices. Revenues associated with our organics services and large scale commercial and industrial services, from our historical lines-of-service of recycling, organics and customer solutions into two lines-of-service: processing and non-processing.
Processing services consist of the receipt of recycled, sludge or other organic materials at one of our materials recovery, processing or disposal facilities, where it is then sorted, mixed and/or processed, and then disposed of or sold. Revenues from processingresource-renewal services are derived from municipalitiesprocessing and customers in the form of processing fees, tipping fees, commodity sales, and organic material sales.non-processing services.
Revenues from non-processing services are derived from brokerage services; overall resource management services providing a wide range of environmental services and zero waste solutions to large and complex organizations; and traditional collection, disposal and recycling services provided to large account multi-site customers. In brokerage arrangements, we act as an agent that facilitates the sale of recyclable materials between an inbound customer and an outbound customer. Revenues from the brokerage of recycled materials are recognized on a net basis at the time of shipment. In general, these fees are variable in nature.

Accrued final capping, closure and post-closure costs include the current and non-current portion of costs associated with obligations for final capping, closure and post-closure of our landfills. We estimate our future final capping, closure and post-closure costs in order to determine the final capping, closure and post-closure expense per ton of waste placed into each landfill. The anticipated time frame for paying these costs varies based on the remaining useful life of each landfill as well as the duration of the post-closure monitoring period.

Credit Facility
As of March 31, 2021,2022, we are party to aan amended and restated credit agreement ("Credit Agreement"), which provides for a $350,000 aggregate principal amount Term Loan Facility and a $200,000$300,000 Revolving Credit Facility.Facility, with a $75,000 sublimit for letters of credit. We have the right to request, at our discretion, an increase in the amount of loans under the Credit Facility by an aggregate amount of $125,000, subject to the terms and conditions set forth in the Credit Agreement. The Credit Facility has a 5-year term that matures in May 2023December 2026 and bears interest at a rate of LIBOR plus 1.75%1.375% per annum, which will be reduced to a rate of LIBOR plus as low as 1.25%1.125% upon us reaching a consolidated net leverage ratio of less than 2.25x. The Credit Facility contains customary benchmark replacement provisions pursuant to which, upon certain triggering events, the LIBOR benchmark used to calculate the LIBOR rate will be replaced with a secured overnight financing rate, as adjusted, on the terms and conditions in the Credit Facility. The Credit Facility is guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries and secured by substantially all of our assets. As of March 31, 2021,2022, further advances were available under the Credit Facility in the amount of $173,575.$252,805. The available amount is net of outstanding irrevocable letters of credit totaling $26,425, at which date$28,195, and as of March 31, 2022 no amount had been drawn.
The Credit Agreement requires us to maintain a minimum interest coverage ratio and a maximum consolidated net leverage ratio, to be measured at the end of each fiscal quarter. As of March 31, 2021, we were in compliance with the covenants contained in the Credit Agreement. In addition to these financial covenants, the Credit Agreement also contains a number of important customary affirmative and negative covenants which restrict, among other things, our ability to sell assets, incur additional debt, create liens, make investments, and pay dividends. We do not believe that these restrictions impact our ability to meet future liquidity needs.
Cash Flow Hedges
Our strategy to reduce exposure to interest rate risk involves entering into interest rate derivative agreements to hedge against adverse movements in interest rates related to the variable rate portion of our long-term debt. We have designated these derivative instruments as highly effective cash flow hedges, and therefore the change in fair value is recorded in our stockholders’ equity as a component of accumulated other comprehensive lossincome (loss), net of tax and included in interest expense at the same time as interest expense is affected by the hedged transactions. Differences paid or received over the life of the agreements are recorded as additions to or reductions of interest expense on the underlying debt and included in cash flows from operating activities.
As of both March 31, 20212022 and December 31, 2020,2021, our active interest rate derivative agreements had total notional amounts of $195,000 and $190,000, respectively.$195,000. According to the terms of the agreements, we receive interest based on the 1-month LIBOR index, in some instances restricted by a 0.0% floor, and pay interest at a weighted average rate of approximately 2.51%2.48%. The agreements mature between June 2022 and February 2027.
Additionally, as of March 31, 2021. The agreements mature between February 2022 and December 2026. As of March 31, 2021, and December 31, 2020, we hadhave forward starting interest rate derivative agreements with total notional amounts of $60,000 and $85,000, and $125,000, respectively.respectively, after considering any forward starting interest rate derivative agreements that have become effective in the current period. According to the terms of the agreements, we will receive interest based on the 1-month LIBOR index, restricted by a 0.0% floor, and will pay interest at a weighted average rate of approximately 1.55%1.44%. The agreements mature between FebruaryJune 2027 and May 2028.

8.    COMMITMENTS AND CONTINGENCIES
Legal Proceedings
In the ordinary course of our business and as a result of the extensive governmental regulation of the solid waste industry, we are subject to various judicial and administrative proceedings involving state and local agencies. In these proceedings, an agency may seek to impose fines or to revoke or deny renewal of an operating permit held by us. From time to time, we may also be subject to actions brought by special interest or other groups, adjacent landowners or residents in connection with the permitting and licensing of landfills and transfer stations, or allegations of environmental damage or violations of the permits and licenses pursuant to which we operate. In addition, we may be named defendants in various claims and suits pending for alleged damages to persons and property, alleged violations of certain laws and alleged liabilities arising out of matters occurring during the ordinary operation of a waste management business. The plaintiffs in some actions seek unspecified damages or injunctive relief, or both. These actions fall within various procedural stages at any point in time, and some are covered in part by insurance.
In accordance with FASB ASC 450 - Contingencies, we accrue for legal proceedings, inclusive of legal costs, when losses become probable and reasonably estimable. We have recorded an aggregate accrual of $1,241 relating to our outstanding legal proceedings as of March 31, 2022. As of the end of each applicable reporting period, we review each of our legal proceedings to determine whether it is probable, reasonably possible or remote that a liability has been incurred and, if it is at least reasonably possible, whether a range of loss can be reasonably estimated under the provisions of FASB ASC 450-20. In instances where we determine that a loss is probable and we can reasonably estimate a range of loss we may incur with respect to such a matter, we record an accrual for the amount within the range that constitutes our best estimate of the possible loss. 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 record an accrual in the amount that is the low end of such range. When a loss is reasonably possible, but not probable, we will not record an accrual, but we will disclose our estimate of the possible range of loss where such estimate can be made in accordance with FASB ASC 450-20. We disclose outstanding matters that we believe could have a material adverse effect on our financial condition, results of operations or cash flows.
North Country Environmental Services Expansion Permit
On October 9, 2020, our subsidiary, North Country Environmental Services, Inc. ("NCES"), received a Type I-A Permit Modification (the "Permit") for Expansion in the Stage VI area of the NCES landfill located in Bethlehem, New Hampshire. On

November 9, 2020, the Conservation Law Foundation ("CLF") filed an appeal of the Permit to the New Hampshire Waste Management Council (the “Council”) on the grounds it failed to meet the public benefit criteria. On January 19, 2021, CLF filed a Complaint for Injunctive Relief with the Grafton Superior Court to enjoin NCES from accepting waste pursuant to the new Permit until such a time as CLF has exhausted its appeal rights. A hearing on the Complaint for Injunctive Relief was held on March 10, 2021; the Grafton Superior Court denied the motion on May 14, 2021. CLF did not appeal this decision. The Council denied NCES’s Motion to Dismiss CLF’s appeal for lack of standing by Order dated March 17, 2021. NCES filed a Motion to Reconsider on March 26, 2021, which was denied by the Council on May 11, 2021. A prehearing conference was held and a schedule for the case was established on June 8, 2021. NCES filed a Motion to Dismiss on the merits of the appeal on June 30, 2021. On July 16, 2021, CLF filed its objection to the Motion to Dismiss, and NCES filed its reply on July 26, 2021. The Council issued an Order on September 3, 2021 granting NCES’s Motion to Dismiss, in part. CLF filed a Motion for Reconsideration on September 23, 2021, and NCES filed its objection on September 28, 2021 and CLF filed a reply on September 30, 2021. CLF’s Motion for Reconsideration was granted on November 19, 2021, and its dismissed claims reinstated. On January 14, 2022, NCES filed a Motion in Limine seeking to exclude from evidence four potential evidentiary items on the basis that those items were either not directly related, or were not included in CLF’s Notice of Appeal. On January 21, 2022, CLF filed an objection to NCES’s motion, and NCES filed a reply on January 26, 2022. On January 31, 2022, the Court issued an Order granting NCES’s Motion in Limine with respect to three of the four items it sought to exclude from evidence, and denying its motion with respect to the remaining item. The hearing on the appeal was held on February 18 and February 22, 2022. Council deliberations concluded on February 22, 2022, ruling in favor of NCES on all motions concerning questions of fact. The hearing officer’s decision with regard to questions of law remains pending. NCES will continue to vigorously defend against this litigation.
Environmental Remediation LiabilityLiabilities
We are subject to liability for environmental damage, including personal injury and property damage, that our solid waste, recycling and power generation facilities may cause to neighboring property owners, particularly as a result of the contamination of drinking water sources or soil, possibly including damage resulting from conditions that existed before we acquired the facilities. We may also be subject to liability for similar claims arising from off-site environmental contamination caused by pollutants or hazardous substances if we or our predecessors arrange or arranged to transport, treat or dispose of those materials. The following matters represent
We accrue for costs associated with environmental remediation obligations when such costs become both probable and reasonably estimable. Determining the method and ultimate cost of remediation requires that a number of assumptions be made. 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 material outstanding claims.

best estimate. In October 2015, our Southbridge Recycling and Disposal Park, Inc. (“SRD”) subsidiary reportedthe early stages of the remediation process, particular components of the overall liability may not be reasonably estimable; in this instance we use the components of the liability that can be reasonably estimated as a surrogate for the liability. 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 Massachusetts Departmentextent such information impacts the costs, timing or duration of Environmental Protection (“MADEP”)the required actions. 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 analysis of samples collected pursuant to our existing permit from private drinking water wells located near the Town of Southbridge, Massachusetts (“Town”) Landfill (“Southbridge Landfill”), which was operated by SRDoperations and later closed in November 2018 when Southbridge Landfill reached its final capacity. Those results indicated the presence of contaminants above the levels triggering notice and response obligations under MADEP regulations. In response to those results, we carried out an Immediate Response Action pursuant to Massachusetts General Law Chapter 21E (the "Charlton 21E Obligations"). Further, we implemented a plan to analyze and better understand the groundwater near the Southbridge Landfill and we investigated with the objective of identifying the sourcecash flows. We disclose outstanding environmental remediation matters that remain unsettled or sources of the elevated levels of contamination measuredare settled in the well samples.reporting period that we believe could have a material adverse effect on our financial condition, results of operations or cash flows.
We entered into an Administrative Consent Order on April 26, 2017 (the “ACO”), with MADEP, the Town, and the Town of Charlton, committing us to equally share the costs with MADEP, of up to $10,000 ($5,000 each) for the Town to install a municipal waterline in the Town of Charlton ("Waterline"). Upon satisfactory completion of that Waterline, and other matters covered by the ACO, we and the Town will be released by MADEP from any future responsibilities for the Charlton 21E Obligations. We also entered into an agreement with the Town on April 28, 2017 entitled the “21E Settlement and Water System Construction Funding Agreement” (the “Waterline Agreement”), wherein we and the Town released each other from claims arising from the Charlton 21E Obligations. Pursuant to the Waterline Agreement, the Town issued a twenty (20) year bond for our portion of the Waterline costs in the amount of $4,089. We have agreed to reimburse the Town for periodic payments under such bond. Construction of the Waterline is complete and homeowners are relying on municipal water supply. Bond reimbursement to the Town commenced in the quarter ended June 30, 2020.
We have recorded an environmental remediation liability related to our obligation associated with installation of the Waterline in other accrued liabilities and other long-term liabilities. We inflate the estimated costs in current dollars to the expected time of payment and discount the total cost to present value using a risk-free interest rate. The weighted average risk-free interest rate associated with our environmental remediation liabilities as of March 31, 2022 ranges between 1.5% and 2.6%. Our expenditures could be significantly higher if costs exceed estimates.

Potsdam Environmental Remediation Liability
On December 20, 2000, the State of New York Department of Environmental Conservation (“DEC”) issued an Order on Consent (“Order”) which named Waste-Stream, Inc. (“WSI”), our subsidiary, General Motors Corporation and Niagara Mohawk Power Corporation (“NiMo”) as Respondents. The Order required that the Respondents undertake certain work on a 25-acre scrap yard and solid waste transfer station owned by WSI in Potsdam, New York, including the preparation of a Remedial Investigation and Feasibility Study (“Study”). A draft of the Study was submitted to the DEC in January 2009 (followed by a final report in May 2009). The Study estimated that the undiscounted costs associated with implementing the preferred remedies would be approximately $10,219. On February 28, 2011, the DEC issued a Proposed Remedial Action Plan for the site and accepted public comments on the proposed remedy through March 29, 2011. We submitted comments to the DEC on this matter. In April 2011, the DEC issued the final Record of Decision (“ROD”) for the site. The ROD was subsequently rescinded by the DEC for failure to respond to all submitted comments. The preliminary ROD, however, estimated that the present cost associated with implementing the preferred remedies would be approximately $12,130. The DEC issued the final ROD in June 2011 with proposed remedies consistent with its earlier ROD. An Order on Consent and Administrative Settlement naming WSI and NiMo as Respondents was executed by the Respondents and DEC with an effective date of October 25, 2013. On January 29, 2016, a Cost-Sharing Agreement was executed between WSI, NiMo, Alcoa Inc. (“Alcoa”) and Reynolds Metal Company (“Reynolds”) whereby Alcoa and Reynolds elected to voluntarily participate in the onsite remediation activities at a combined 15% participant share. The majority of the remediation work has been completed as of March 31, 2021. WSI is jointly and severally liable with NiMo, Alcoa and Reynolds for the total cost to remediate.
We have recorded an environmental remediation liability associated with the Potsdam site based on incurred costs to date and estimated costs to complete the remediation in other accrued liabilities and other long-term liabilities. We inflate the estimated costs in current dollars to the expected time of payment and discount the total cost to present value using a risk-free interest rate of 1.9%. The environmental remediation liability associated with the Potsdam site was $939 as of both March 31, 2021 and December 31, 2020.
Legal Proceedings
North Country Environmental Services
On or about March 8, 2018, NELC and the Conservation Law Foundation ("CLF") (the "NH Citizen Groups") delivered correspondence to our subsidiary, North Country Environmental Services, Inc. ("NCES"), and us, providing notice of the NH Citizen Groups' intent to sue NCES and us for violations of the CWA in conjunction with NCES's operation of its landfill in Bethlehem, New Hampshire ("NCES Landfill"). On May 14, 2018, the NH Citizen Groups filed a lawsuit against NCES and us in the United States District Court for the District of New Hampshire (the “New Hampshire Court”) alleging violations of the CWA, arguing that ground water discharging into the Ammonoosuc River is a "point source" under the CWA (the "New Hampshire Litigation"). The New Hampshire Litigation seeks remediation and fines under the CWA and an order requiring NCES to seek a Federal National Pollutant Discharge Elimination System permit for the operation of the NCES Landfill. On June 15, 2018, we and NCES filed a Motion to Dismiss the New Hampshire Litigation. On July 13, 2018, the NH Citizen Groups filed objections to our Motion to Dismiss. On July 27, 2018, we filed a reply in support of our Motion to Dismiss. On September 25, 2018, the New Hampshire Court denied our Motion to Dismiss. In March of 2019, we filed a motion in the New Hampshire Litigation asking for a stay of this litigation until certain appeals from discordant federal circuit courts were heard by the Supreme Court of the United States (“SCOTUS”), in the case identified as “County of Maui v. Hawaii Wildlife Fund (“MAUI”)". Our motion for a stay was granted in the New Hampshire Litigation, and SCOTUS heard the case in 2019 and issued a ruling on April 23, 2020. SCOTUS remanded the case to the U.S. Court of Appeals for the Ninth Circuit in San Francisco (the “Circuit Court”) ruling that the Circuit Court’s standard as to whether ground water impacts to navigable waters is too broad. We do not believe that the MAUI decision resolves the issues presented in the New Hampshire Litigation, and until the Circuit Court rules in the remanded MAUI case, we intend to continue to vigorously defend against the New Hampshire Litigation, which we believe is without merit. The NH Citizens Groups filed a motion with the New Hampshire Court on July 15, 2020 to amend their complaint based on MAUI. The New Hampshire Court granted the NH Citizen Groups' motion on September 2, 2020 and encouraged the parties to file motions for summary judgment. We filed our Motion for Summary Judgment on November 20, 2020 and the NH Citizens Groups filed a Motion for Summary Judgment on February 19, 2021. A hearing on motions for summary judgment is scheduled for May 14, 2021.
On October 9, 2020, we received a Type I-A Permit Modification for Expansion in the Stage VI area of the NCES Landfill (the “Permit”). On November 9, 2020, CLF filed an appeal of the Permit to the New Hampshire Waste Management Council on the grounds it failed to meet the public benefit criteria. On January 19, 2021, CLF filed a Complaint for Injunctive Relief with the Grafton Superior Court to enjoin NCES from accepting waste pursuant to the new Permit until such a time as CLF has exhausted its appeal rights. A hearing on the Complaint for Injunctive Relief was held on March 10, 2021; the Grafton Superior Court has not yet issued a decision. The Grafton Superior Court denied our Motion to Dismiss by Order dated March 17, 2021. We filed a Motion to Reconsider on March 26, 2021. We will continue to vigorously defend against this litigation.

Hakes Landfill Litigation
On or about December 19, 2019, the New York State Department of Environmental Conservation (“Department”) issued certain permits to us to expand the landfill owned and operated by Hakes C&D Disposal Inc. in the Town of Campbell, Steuben County, New York (“Hakes Landfill”). The permits authorize approximately five years of expansion capacity at the Hakes Landfill. The authorizations issued by the Department followed approvals issued by the Town of Campbell Planning Board (“Planning Board”) in January 2019, and the Town Board of the Town of Campbell (“Town Board”) in March 2019, granting site plan review and a zoning change for the project.
Litigation was commenced by the Sierra Club, several other non-governmental organizations, and several individuals (“the Petitioners”), challenging the approvals issued by the Department, the Planning Board and the Town Board in New York State Supreme Court, Steuben County (the “Hakes Litigation”). The challenge was based upon allegations that the agencies issuing these approvals did not follow the requirements of Article 8 of the Environmental Conservation Law of the State of New York, the State Environmental Quality Review Act (“SEQRA”), by failing to address certain radioactivity issues alleged by Petitioners to be associated with certain drilling wastes authorized for disposal at the Hakes Landfill. The Department opposed the Hakes Litigation on procedural grounds. We and the Town of Campbell opposed the Hakes Litigation on the merits, and on July 31, 2020, the Court dismissed the Hakes Litigation on the merits. The Petitioners filed a notice of appeal. The time to appeal expired on February 10, 2021, and the attorney for the Petitioners confirmed that they are not pursuing the appeal. Accordingly, all approvals issued for the expansion project are now final and binding.
Ontario County, New York Class Action Litigation
On or about September 17, 2019, Richard Vandemortel and Deb Vandemortel ("Named Plaintiffs") filed a class action complaint against us in Ontario County Supreme Court (the "New York Court") on behalf of similarly situated citizens ("Class Members") in Ontario County, New York (the "New York Litigation"). The New York Litigation alleges that over one thousand (1,000) citizens constitute the putative class in the New York Litigation, and it seeks damages for diminution of property values and infringement of the putative class’ rights to live without interference to their daily lives due to odors emanating from the Subtitle D landfill located in Seneca, New York , which is operated by us pursuant to a long-term Operation, Maintenance and Lease Agreement with Ontario County. The New York Litigation was served on us on October 14, 2019, and the parties commenced settlement negotiations in early 2020. On December 1, 2020, the parties entered into a settlement agreement (the "Settlement Agreement") and thereafter the Named Plaintiffs and Class Members' counsel ("Counsel") moved the New York Court for entry of the Order on Notice/Preliminary Approvals. The settlement includes a $750 payment to a Qualified Settlement Fund for the benefit of Counsel and one-time lump sum payments to the Named Plaintiffs and Class Members who opt into the Settlement Agreement. We will also commit $900 in expenses and capital improvements for remediation measures to be completed by December 31, 2022.
Conservation Law Foundation, Inc. v Robert R. Scott, Commissioner, New Hampshire Department of Environmental Services
On or about February 11, 2021, the CLF filed a complaint against Robert R. Scott, Commissioner of the New Hampshire Department of Environmental Services (“DES”), in the Merrimac County Superior Court. The complaint alleges that DES has failed to comply with the duty to establish and update a solid waste plan for the State of New Hampshire, and the duty to rely on that solid waste plan in determining whether to grant permits for proposed waste disposal facilities, and seeks a declaratory judgment that DES is violating statutory solid waste planning and regulatory requirements; a writ of mandamus ordering DES to achieve compliance with the statutory solid waste plan requirement; and an order enjoining DES from reviewing, and issuing decisions on, permit applications for new or expanded waste facilities, including a landfill under development by us in Dalton, New Hampshire ("Granite State Landfill"), as well as any further review and decision-making required for permits it has already granted, including our NCES Landfill, until it has a legally valid state solid waste plan. On or about February 16, 2021, our subsidiary, Granite State Landfill, LLC, filed a Motion to Intervene in the action, which was granted by the Merrimac County Superior Court on February 17, 2021. A hearing on CLF's request for preliminary injunctive relief and the parties' motions to dismiss was held April 9, 2021. Post-hearing filings were due April 23, 2021.

9.    STOCKHOLDERS' EQUITY
Stock Based Compensation
Shares Available For Issuance
In the fiscal year ended December 31, 2016, we adopted the 2016 Incentive Plan (“2016 Plan”). Under the 2016 Plan, we may grant awards up to an aggregate amount of shares equal to the sum of: (i) 2,250 shares of Class A common stock (subject to adjustment in the event of stock splits and other similar events), plus (ii) such additional number of shares of Class A common stock (up to 2,723 shares) as is equal to the sum of the number of shares of Class A common stock that remained available for grant under the 2006 Stock Incentive Plan (“2006 Plan”) immediately prior to the expiration of the 2006 Plan and the number of shares of Class A common stock subject to awards granted under the 2006 Plan that expire, terminate or are otherwise surrendered, canceled, forfeited or repurchased by us. As of March 31, 2021,2022, there were 950811 Class A common stock equivalents available for future grant under the 2016 Plan.
Stock Options
Stock options are granted at a price equal to the prevailing fair value of our Class A common stock at the date of grant. Generally, stock options granted have a term not to exceed ten years and vest over a one-year to four-year period from the date of grant.
The fair value of each stock option granted is estimated using a Black-Scholes option-pricing model, which requires extensive use of accounting judgment and financial estimation, including estimates of the expected term stock option holders will retain their vested stock options before exercising them and the estimated volatility of our Class A common stock price over the expected term.

Other Stock Awards
Restricted stock awards, restricted stock units and performance stock units, with the exception of market-based performance stock units, are granted at a price equal to the fair value of our Class A common stock at the date of grant. The fair value of each market-based performance stock unit is estimated using a Monte Carlo pricing model, which requires extensive use of accounting judgment and financial estimation, including the estimated share price appreciation plus, if applicable, the value of dividends of our Class A common stock as compared to the Russell 2000 Index over the requisite service period.
Generally, restricted stock awards granted to non-employee directors vest incrementally over a three year period beginning on the first anniversary of the date of grant. Restricted stock units granted to non-employee directors vest in full on the first anniversary of the grant date. Restricted stock units granted to employees vest incrementally over an identified service period beginning on the grant date based on continued employment. Performance stock units granted to employees, including market-based performance stock units, vest at a future date following the grant date and are based on the attainment of performance targets and market achievements, as applicable.

10.    EARNINGS PER SHARE
Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated based on the combined weighted average number of common shares and potentially dilutive shares, which include the assumed exercise of employee stock options, unvested restricted stock awards, unvested restricted stock units and unvested performance stock units, including market-based performance units based on the expected achievement of performance targets. In computing diluted earnings per share, we utilize the treasury stock method.

11.    OTHER ITEMS AND CHARGES
Expense from Acquisition Activities
In the three months ended March 31, 20212022 and 2020,2021, we recorded charges of $414$2,043 and $1,009,$414, respectively, comprised primarily of legal, consulting and other similar costs associated with the acquisition and integration of acquired businesses or select development projects.
Southbridge Landfill Closure Charge
In 2017, we initiated the plan to cease operations of the Southbridge Landfill and later closed it in November 2018 when Southbridge Landfill reached its final capacity. Accordingly, in the three months ended March 31, 2021 and 2020, we recorded charges of $157 and $613, respectively, associated with legal and other costs pertaining to various matters as part of the unplanned early closure of the Southbridge Landfill through completion of the closure process.
12.    FAIR VALUE OF FINANCIAL INSTRUMENTS
We use a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. These tiers include: Level 1, defined as quoted market prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; and Level 3, defined as unobservable inputs that are not corroborated by market data.
We use valuation techniques that maximize the use of market prices and observable inputs and minimize the use of unobservable inputs. In measuring the fair value of our financial assets and liabilities, we rely on market data or assumptions that we believe market participants would use in pricing an asset or a liability.
20


Assets and Liabilities Accounted for at Fair Value
Our financial instruments include cash and cash equivalents, accounts receivable, restricted investment securities held in trust on deposit with various banks as collateral for our obligations relative to our landfill final capping, closure and post-closure costs, interest rate swaps,derivatives, contingent consideration related to acquisitions, trade payables and long-term debt. The carrying values of cash and cash equivalents, accounts receivable and trade payables approximate their respective fair values due to their short-term nature. The fair value of restricted investment securities held in trust, which are valued using quoted market prices, are included as restricted assets in the Level 1 tier below. The fair value of the interest rate swapsderivatives included in the Level 2 tier below is calculated using discounted cash flow valuation methodologies based upon the one-month LIBOR yield curves that are observable at commonly quoted intervals for the full term of the swaps. We recognize all derivatives accounted for on the balance sheet at fair value.

Fair Value of Debt
As of March 31, 2021,2022, the fair value of our fixed rate debt, including our FAME Bonds 2005R-3, FAME Bonds 2015R-1, FAME Bonds 2015R-2, Vermont Bonds, New York Bonds 2014R-1, New York Bonds 2014R-2, New York Bonds 2020 and New Hampshire Bonds was approximately $173,090$165,864 and the carrying value was $162,000. The fair value of the FAME Bonds 2005R-3, the FAME Bonds 2015R-1, the FAME Bonds 2015R-2, the Vermont Bonds, the New York Bonds 2014R-1, the New York Bonds 2014R-2, New York Bonds 2020 and the New Hampshire Bonds is considered to be Level 2 within the fair value hierarchy as the fair value is determined using market approach pricing provided by a third-party that utilizes pricing models and pricing systems, mathematical tools and judgment to determine the evaluated price for the security based on the market information of each of the bonds or securities with similar characteristics.
As of March 31, 2021,2022, the carrying value of our Term Loan Facility was $349,125$350,000 and the carrying value of our Revolving Credit Facility was $0.$19,000. Their fair values are based on current borrowing rates for similar types of borrowing arrangements, or Level 2 inputs, and approximate their carrying values.
Although we have determined the estimated fair value amounts of FAME Bonds 2005R-3, FAME Bonds 2015R-1, FAME Bonds 2015R-2, Vermont Bonds, New York Bonds 2014R-1, New York Bonds 2014R-2, New York Bonds 2020 and New Hampshire Bonds using available market information and commonly accepted valuation methodologies, a change in available market information, and/or the use of different assumptions and/or estimation methodologies could have a material effect on the estimated fair values. These amounts have not been revalued, and current estimates of fair value could differ significantly from the amounts presented.

13.    SEGMENT REPORTING
We report selected information about our reportable operating segments in a manner consistent with that used for internal management reporting. We classify our solid waste operations on a geographic basis through regional operating segments, our Western and Eastern regions. Revenues associated with our solid waste operations are derived mainly from solid waste collection, transfer, transportation and disposal, landfill landfill gas-to-energy, processing, transfer and recycling services in the northeastern United States. Effective January 1, 2021, we reorganized theOur Resource Solutions operating segment which includesleverages our larger-scale recycling and commodity brokerage operations along with our organics services and large scale commercial andcore competencies in materials processing, industrial services, from our historical lines-of-service of recycling, organics and customer solutions intoresource management service offerings to deliver a comprehensive solution for our larger commercial, municipal, institutional and industrial customers that have more diverse waste and recycling needs. Revenues associated with our Resource Solutions operations are derived from two lines-of-service: processing and non-processing. Revenues from processing services are derived from municipalities and customers in the form of processing fees, tipping fees, commodity sales, and organic material sales. Revenues from non-processing services are derived from brokerage services;services and overall resource management services providing a wide range of environmental services and zero waste solutions to large and complex organizations; andorganizations, as well as traditional collection, disposal and recycling services provided to large account multi-site customers. Revenues classification by service line reported in the three months ended March 31, 2020 has been reclassified to conform with the presentation for the three months ended March 31, 2021. Legal, tax, information technology, human resources, certain finance and accounting and other administrative functions are included in our Corporate Entities segment, which is not a reportable operating segment. Corporate Entities results reflect those costs not allocated to our reportable operating segments.

Company Overview
Founded in 1975 with a single truck, Casella Waste Systems, Inc., a Delaware corporation, and its wholly-owned subsidiaries (collectively, “we”, “us” or “our”), is a regional, vertically-integratedvertically integrated solid waste services company. We provide resource management expertise and services to residential, commercial, municipal, institutional and industrial customers, primarily in the areas of solid waste collection and disposal, transfer, recycling and organics services. We provide integrated solid waste services in sixseven states: Vermont, New Hampshire, New York, Massachusetts, Connecticut, Maine and Pennsylvania, with our headquarters located in Rutland, Vermont. We manage our solid waste operations on a geographic basis through two regional operating segments, the Eastern and Western regions, each of which provides a full range of solid waste services. We manage our resource-renewal operations through the Resource Solutions operating segment, which includesleverages our larger-scalecore competencies in materials processing, industrial recycling, organics and commodityresource management service offerings to deliver a comprehensive solution for our larger commercial, municipal, institutional and industrial customers that have more diverse waste and recycling needs. Our Resources Solutions operations consist of two lines-of-service: processing and non-processing. Processing services consist of the receipt of recycled, sludge or other organic materials at one of our materials recovery, processing or disposal facilities, where it is then sorted, mixed and/or processed, and then disposed of or sold. Non-processing services consist of brokerage operations along with our organics services and overall resource management services, which provide a wide range of environmental services and zero waste solutions to large scale commercial and industrial services.complex organizations, as well as traditional collection, disposal and recycling services provided to large account multi-site customers.

Results of Operations
Recent Events
The global outbreak of the novel coronavirus ("COVID-19") pandemic has caused, and is expected to continue to cause, economic disruption across our geographic footprint and has adversely affected, and is expected to continue to adversely affect, our business. The COVID-19 pandemic negatively impacted our revenues starting at the end of the three months ended March 31, 2020, as many small business and construction collection customers required service level changes and volumes into our landfills declined due to lower economic activity. Although demand for services has improved as local economies begin to reopen as allowed by State Governments, our collection and disposal operations continued to be negatively impacted by lower volumes attributable to the COVID-19 pandemic in the three months ended March 31, 2021.
The COVID-19 pandemic has negatively impacted and is expected to continue to impact our business in other ways, as we have experienced and continue to experience increased costs as a result of the COVID-19 pandemic, including, but not limited to, higher costs associated with providing a safe working environment for our employees (such as increased costs associated with the protection of our employees, including costs for additional safety equipment, hygiene products and enhanced facility cleaning), employee impacts from illness, supporting a remote administration workforce, community response measures, the inability of customers to continue to pay for services, and temporary closures of the facilities of our customers. We have taken measures to reduce costs in other areas and preserve liquidity during this period of uncertainty. As of the date of this filing, we are unable to determine or predict the full extent of the continuing impact that the COVID-19 pandemic will have on our business, results of operations, liquidity and capital resources. Future developments, such as the possibility of continuing spread of COVID-19 across our geographic footprint, the rate of vaccinations, the severity and containment of certain COVID-19 variants along with the pace and extent to which the States in which we operate facilitate a return to normal economic and operation conditions are uncertain and cannot be predicted at this time.
Revenues
We manage our solid waste operations, which include a full range of solid waste services, on a geographic basis through two regional operating segments, which we designate as the Eastern and Western regions. Revenues in our Eastern and Western regions consist primarily of fees charged to customers for solid waste collection and disposal services, including landfill, transfer and transportation, landfill gas-to-energy, transfer and recyclingprocessing services. We derive a substantial portion of our collection revenues from commercial, industrial and municipal services that are generally performed under service agreements or pursuant to contracts with municipalities. The majority of our residential collection services are performed on a subscription basis with individual households. Landfill and transfer customers are charged a tipping fee on a per ton basis for disposing of their solid waste at our disposal facilities and transfer stations. We also generate and sell electricity at certain of our landfill facilities.

Cost of Operations
Cost of operations includes labor costs, tipping fees paid to third-party disposal facilities, fuel costs, maintenance and repair costs of vehicles and equipment, workers’ compensation and vehicle insurance costs, the cost of purchasing materials to be recycled, third-party transportation costs, district and state taxes, host community fees and royalties. Cost of operations also includes accretion expense related to final capping, closure and post-closure obligations, leachate treatment and disposal costs and depletion of landfill operating lease obligations.
As a percentage of revenues, cost of operations decreased 320increased 230 basis points during the three months ended March 31, 20212022 from the same period of the prior year. The period-to-period change in cost of operations can be primarily attributed to the following:
Third-party direct costs decreased $(2.2)increased $12.7 million quarterly, while decreasing 210increasing 70 basis points as a percentage of revenues, due to the following:
lower hauling andhigher third-party transportationdisposal costs associated with lowerincreased solid waste volumes on acquisition activity, and to a lesser extent, organic collection volumes, lower landfill volumesgrowth, and higher fuel surcharges from third-party transporters;

General and administration expense includesexpenses include management, clerical and administrative compensation bad debt expense, as well asand overhead, costs, professional service feesservices and costs associated with marketing, sales force and community relations efforts.
The period-to-period change in general and administration expense can be primarily attributed to higherincreased overhead costs associated with wage inflation and business growth, partially offset by lower equity compensation costs and higher accrued incentive compensation on improved performance; partially offset by lower bad debt expense attributed to the timing of the COVID-19 pandemic, which resulted in a large increase in the allowance for credit losses as of March 31, 2020.expense.
Depreciation and Amortization
Depreciation and amortization expense includes: (i) depreciation of property and equipment (including assets recorded for finance leases) on a straight-line basis over the estimated useful lives of the assets; (ii) amortization of landfill costs (including those costs incurred and all estimated future costs for landfill development and construction, along with asset retirement costs arising from closure and post-closure obligations) on a units-of-consumption method as landfill airspace is consumed over the total estimated remaining capacity of a site, which includes both permitted capacity and unpermitted expansion capacity that meets certain criteria for amortization purposes, and amortization of landfill asset retirement costs arising from final capping obligations on a units-of-consumption method as airspace is consumed over the estimated capacity associated with each final capping event; and (iii) amortization of intangible assets with a definite life, using either an economic benefit provided approach or on a straight-line basis over the definitive terms of the related agreements.

Expense from Acquisition Activities
In the three months ended March 31, 20212022 and 2020,2021, we recorded charges of $0.4$2.0 million and $1.0$0.4 million, respectively, comprised primarily of legal, consulting and other similar costs associated with the acquisition and integration of acquired businesses or select development projects.
Southbridge Landfill Closure Charge
In 2017, we initiated the plan to cease operations of the Southbridge Landfill and later closed it in November 2018 when Southbridge Landfill reached its final capacity. Accordingly, in the three months ended March 31, 2021 and 2020, we recorded charges of $0.2 million and $0.6 million, respectively, associated with legal and other costs pertaining to various matters as part of the unplanned early closure of the Southbridge Landfill through completion of the closure process.
Other Expenses

Interest Expense, net
Our interest expense, net decreased $(0.5)$(0.2) million quarterly due primarily to lower average interest rates on our debt associated with changes in LIBOR.a lower interest rate spread associated with our amended and restated credit agreement ("Credit Agreement"), partially offset by higher average debt balances associated with borrowings against our amended and restated revolving credit facility ("Revolving Credit Facility").
Provision for Income Taxes
Our provision for income taxes increased $2.3decreased $(1.5) million quarterly as compared to the same period in the prior year.year, primarily due to the lower income from operations and the difference in the one-time adjustments for the tax benefit on equity compensation awards between the periods. The provision for income taxes in the three months ended March 31, 2021 includes $0.12022 included $0.5 million of current income taxes and $2.3$0.5 million of deferred income taxes. For the three months ended March 31, 2020,2021, the provision includesincluded a $(0.9)$(0.1) million current income tax benefit and $1.0$2.3 million of deferred income taxes. The effective rate for the three months ended March 31, 2021 is2022 was 31%, before adjustment for the one-time adjustments primarily related to tax effects of accumulated other comprehensive losses and equity compensation, and is computed based on the statutory rate of 21%, adjusted primarily for state taxes and nondeductible officer compensation.
An increase of $1.3 million in the deferred tax provision between the periods relates to the release of a significant portion of our valuation allowance in the fourth quarter ended December 31, 2020. On a periodic basis, we reassess the valuation allowance on our deferred income tax assets, weighing positive and negative evidence to assess the recoverability of the deferred tax assets. In the fourth quarter ended December 31, 2020, we assessed the valuation allowance and considered positive evidence, including significant cumulative consolidated income over the three years ended December 31, 2020, revenue growth and expectations of future profitability, and negative evidence, including the impact of a negative change in the economic climate, significant risks and uncertainties in the business and restrictions on tax loss utilization in certain state jurisdictions. After assessing both the positive evidence and the negative evidence, we determined it was more likely than not that the majority of our deferred tax assets would be realized in the future and released the valuation allowance on the majority of our net operating loss carryforwards and other deferred tax assets as of December 31, 2020, resulting in a benefit from income taxes of $61.3 million. We continues to maintain a valuation allowance related to deferred tax assets that would generate capital losses when realized and deferred tax assets related to certain state jurisdictions.
On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted which, among other things, allows the carryback of remaining minimum tax credit carryforwards to tax year 2018. Prior to the CARES Act, the minimum tax credit carryforwards were fully refunded through tax year 2021, if not otherwise used to offset tax liabilities. A current income tax benefit of $(1.0) million, offset by a $1.0 million deferred tax provision, was recognized in the three months ended March 31, 2020 for the remaining minimum tax credit carried back to tax year 2018.
On December 22, 2017, the Tax Cuts and Jobs Act (the “TCJ Act”) was enacted. The TCJ Act significantly changed U.S. corporate income tax laws by, among other things, changing carryforward rules for net operating losses. Our $92.5$52.4 million in federal net operating loss carryforwards generated as of the end of 2017 continue to be carried forward for 20 years and are expected to be available to fully offset taxable income earned in 2021the fiscal year ending December 31, 2022 ("fiscal year 2022") and future tax years. Federal net operating losses generated after 2017, totaling $46.5 million carried forward to 2021,fiscal year 2022, will be carried forward indefinitely, but generally may only offset up to 80% of taxable income earned in a tax year.

Outstanding Long-Term Debt
Credit Facility
As of March 31, 2021,2022, we had outstanding $349.1$350.0 million aggregate principal amount of borrowings under our term loan A facility ("Term Loan Facility") and $19.0 million in borrowings under our $300.0 million Revolving Credit Facility, with a $75.0 million sublimit for letters of credit.(the Term Loan Facility and $0.0 million aggregate principal amount of borrowings under our $200.0 millionthe Revolving Credit Facility.Facility together, the “Credit Facility”). The Credit Facility has a 5-year term that matures in May 2023December 2026 and bears interest at a rate of LIBOR plus 1.75%1.375% per annum, which will be reduced to a rate of LIBOR plus as low as 1.25%1.125% upon us reaching a consolidated net leverage ratio of less than 2.25x. OurThe Credit Facility contains customary benchmark replacement provisions pursuant to which, upon certain triggering events, the LIBOR benchmark used to calculate the LIBOR rate will be replaced with a secured overnight financing rate, as adjusted, on the terms and conditions in the Credit Facility. The Credit Facility is guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries and secured by substantially all of our assets. As of March 31, 2021,2022, further advances were available under the Revolving Credit Facility in the amount of $173.6$252.8 million. The available amount is net of outstanding irrevocable letters of credit totaling $26.4$28.2 million, at which dateand as of March 31, 2022 no amount had been drawn. We have the right to request, at our discretion, an increase in the amount of loans under the Credit Facility by an aggregate amount of $125.0 million, subject to the terms and conditions set forth in the credit agreement ("Credit Agreement").Agreement.
33


The Credit Agreement requires us to maintain a minimum interest coverage ratio and a maximum consolidated net leverage ratio, to be measured at the end of each fiscal quarter. As of March 31, 2021, financial covenant requirements included a minimum interest coverage ratio of 3.00 times and a maximum consolidated net leverage ratio of 4.00 times. In addition to thethese financial covenants, described above, the Credit Agreement also contains a number of important customary affirmative and negative covenants which restrict, among other things, our ability to sell assets, incur additional debt, create liens, make investments, and pay dividends. As of March 31, 2022, we were in compliance with the covenants contained in the Credit Agreement. We do not believe that these restrictions impact our ability to meet future liquidity needs. AsAn event of March 31, 2021,default under any of our debt agreements could permit some of our lenders, including the lenders under the Credit Facility, to declare all amounts borrowed from them to be immediately due and payable, together with accrued and unpaid interest, or, in the case of the Credit Facility, terminate the commitment to make further credit extensions thereunder, which could, in turn, trigger cross-defaults under other debt obligations. If we were unable to repay debt to our lenders or were otherwise in compliance with all covenants contained indefault under any provision governing our outstanding debt obligations, our secured lenders could proceed against us and against the Credit Agreement.collateral securing that debt.
Based on the seasonality of our business, operating results in the late fall, winter and early spring months are generally lower than the remainder of our fiscal year. Given the cash flow impact that this seasonality, the capital intensive nature of our business and the timing of debt payments has on our business, we typically incur higher debt borrowings in order to meet our liquidity needs during these times. Consequently, our availability and performance against our financial covenants may tighten during these times as well.
Tax-Exempt Financings and Other Debt
As of March 31, 2021,2022, we had outstanding $162.0 million aggregate principal amount of tax exempt bonds, $34.6$44.8 million aggregate principal amount of finance leases and $4.5$4.4 million aggregate principal amount of notes payable. See Note 7, Debt to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for further disclosure over debt.
Inflation
Although inflationaryInflationary increases in costs, including current inflationary pressures associated primarily with fuel, labor and certain capital items, have affected, and may continue to affect, our historical operating margins. While rapid inflation negatively impacted operating results and margins during the three months ended March 31, 2022, we believe that our flexible pricing structures and mature cost recovery fees will allow us to recover certain of the cost of inflation generally has not had a significant impact onfrom our operating results.customer base. Consistent with industry practice, most of our contracts provide for a pass-through of certain costs to our customers, including increases in landfill tipping fees and in some cases fuel costs, intended to mitigate the impact of inflation on our operating results. We have also implemented a number of operating efficiency programs that seek to improve productivity and reduce our service costs, and a fuel surcharge, which is designed to recover escalating fuel price fluctuations above an annually reset floor. Based onDespite these implementations, we believe we should be able to sufficiently offset most cost increases resulting from inflation. However,programs, competitive factors may require us to absorb at least a portion of these cost increases. Additionally, management’s estimates associated with inflation have had, and will continue to have, an impact on our accounting for landfill and environmental remediation liabilities.
Regional Economic Conditions
Our business is primarily located in the northeastern United States. Therefore, our business, financial condition and results of operations are susceptible to downturns in the general economy in this geographic region and other factors affecting the region, such as state regulations and severe weather conditions. There can be no assurance thatWe are unable to forecast or determine the economic conditions intiming and/or the northeastern United States will recover from thefuture impact of the COVID-19 pandemic at the same time as, or at the same rate as, other areas of the United States.a sustained economic slowdown.

Seasonality and Severe Weather
Our transfer and disposal revenues historically have been higher in the late spring, summer and early fall months. This seasonality reflects lower volumes of waste in the late fall, winter and early spring months because:
because the volume of waste relating to C&D activities decreases substantially during the winter months in the northeastern United States; and
decreased tourism in Vermont, New Hampshire, Maine and eastern New York during the winter months tends to lower the volume of waste generated by commercial and restaurant customers, which is partially offset by increased volume from the ski industry.States.
Because certain of our operating and fixed costs remain constant throughout the fiscal year, operating income is therefore impacted by a similar seasonality. Our operations can be adversely affected by periods of inclement or severe weather, which could increase our operating costs associated with the collection and disposal of waste, delay the collection and disposal of waste, reduce the volume of waste delivered to our disposal sites, increase the volume of waste collected under our existing contracts (without corresponding compensation), decrease the throughput and operating efficiency of our materials recycling facilities, or delay construction or expansion of our landfill sites and other facilities. Our operations can also 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 provided.
Our processing line-of-business in the Resource Solutions operating segment experiences increased volumes of fiber in November and December due to increased retail activity during the holiday season.

Critical Accounting PoliciesEstimates and EstimatesAssumptions
The preparation of ourOur financial statements requires management to makehave been prepared in accordance with generally accepted accounting principles in the United States and necessarily include certain estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities, as applicable, at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.judgments made by management. On an on-going basis, management evaluates its estimates and judgments which are based on historical experience and on various other factors that are believed to be reasonable under the circumstances. The results of their evaluation form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions and circumstances. Except for the adoption of the newOur critical accounting standardsestimates are more fully discussed in Note 2, Item 7, "Accounting ChangesManagement's Discussion and Analysis of Financial Condition and Results of Operations to our consolidated financial statements included under Part I, Item 1 of this Quarterly Report on Form 10-Q, there were no material changes in the three months ended March 31, 2021 to the application of critical accounting policies and estimates as described in Item 8" of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.2021.
New Accounting Pronouncements
For a description of the new accounting standards that may affect us, see Note 2, Accounting Changes to our consolidated financial statements included under Part I, Item 1 of this Quarterly Report on Form 10-Q.
ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
In the normal course of business we are exposed to market risks, including changes in interest rates and certain commodity prices. We have a variety of strategies to mitigate these market risks, including at times using derivative instruments to hedge some portion of these risks.
Interest Rate Volatility
Our strategy to reduce exposure to interest rate risk involves entering into interest rate derivative agreements to hedge against adverse movements in interest rates related to the variable rate portion of our long-term debt. We have designated these derivative instruments as highly effective cash flow hedges, and therefore the change in fair value is recorded in our stockholders’ equity as a component of accumulated other comprehensive loss and included in interest expense at the same time as interest expense is affected by the hedged transactions. Differences paid or received over the life of the agreements are recorded as additions to or reductions of interest expense on the underlying debt and included in cash flows from operating activities.

According to the terms of the agreements, we receive interest based on the 1-month LIBOR index, in some instances restricted by a 0.0% floor, and pay interest at a weighted average rate of approximately 2.51%2.48% as of March 31, 2021.2022. The agreements mature between FebruaryJune 2022 and December 2026. AsFebruary 2027. Additionally, as of March 31, 2021 and December 31, 2020,2022, we hadhave forward starting interest rate derivative agreements with a total notional amountamounts of $85.0$60.0 million that mature between June 2027 and $125.0 million, respectively. According to the terms of the agreements, weMay 2028. We will receive interest based on the 1-month LIBOR index, restricted by a 0.0% floor, and will pay interest at a weighted average rate of approximately 1.55%1.44%. The agreements mature between February 2027 and May 2028.
As of March 31, 2021,2022, we had $201.1$211.2 million of fixed rate debt in addition to the $195.0 million fixed through our interest rate derivative agreements. We had interest rate risk relating to approximately $154.1$174.0 million of long-term debt as of March 31, 2021.2022. The weighted average interest rate on the variable rate portion of long-term debt was approximately 1.9%1.8% at March 31, 2021.2022. Should the average interest rate on the variable rate portion of long-term debt change by 100 basis points, we estimate that our annual interest expense would change by up to approximately $1.5$1.7 million.
Commodity Price Volatility
Information about commodity marketprice volatility market risk as of March 31, 20212022 does not differ materially from that discussed in Part II, Item 7A, "Quantitative and Qualitative Disclosures About Market Risk" of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.2021.

ITEM 4.    CONTROLS AND PROCEDURES
Evaluation of disclosure controls and procedures. Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2021.2022. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2021,2022, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.
Changes in internal controls over financial reporting. No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the three months ended March 31, 20212022 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

The information required by this Item is provided in Note 8, Commitments and Contingencies to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Legal Proceedings over Certain Environmental Matters Involving Governmental Authorities with Possible Sanctions of $1,000,000 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 a specified threshold which we determine is reasonably designed to result in disclosure of any such proceeding that is material to our business or financial condition. Pursuant to Item 103, we have determined such disclosure threshold to be $1,000,000. We have no matters to disclose in accordance with that requirement.
37


ITEM 1A.    RISK FACTORS
Our business is subject to a number of risks, including those identified in Item 1A, “Risk Factors”Risk Factors of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 ("2020 10-K"),2021, that could have a material effect on our business, results of operations, financial condition and/or liquidity and that could cause our operating results to vary significantly from period to period.
